PROSPECTUS SUMMARY

IN THIS PROSPECTUS, "TRANSDIGM" REFERS TO TRANSDIGM INC., THE ISSUER OF THE NOTES, AND ITS SUBSIDIARIES. THE TERM "HOLDINGS" REFERS TO THE PARENT HOLDING COMPANY OF TRANSDIGM, WHICH HAS NO ASSETS OTHER THAN TRANSDIGM CAPITAL STOCK. THE FOLLOWING SUMMARY CONTAINS BASIC INFORMATION ABOUT TRANSDIGM AND THIS EXCHANGE OFFER. IT DOES NOT CONTAIN ALL THE INFORMATION THAT IS IMPORTANT TO YOU. FOR A MORE COMPLETE UNDERSTANDING OF THIS EXCHANGE OFFER, WE ENCOURAGE YOU TO READ THIS ENTIRE DOCUMENT AND THE DOCUMENTS WE HAVE REFERRED YOU TO.

TRANSDIGM INC.
8233 Imperial Drive
Waco, Texas 76712
(254) 776-0650

We are a leading supplier of highly engineered aircraft components for use on nearly all commercial and military aircraft. We sell our products to commercial airlines, such as United Airlines and Continental Airlines, large commercial transport and regional and business aircraft original equipment manufacturers, such as Boeing, Bombardier and Cessna, and various agencies of the United States government. We compete in niche individual aircraft component markets that we estimate range in size from $10 million to $100 million in annual revenues. For fiscal 1998 on a pro forma basis after giving effect to the offering of the Old Notes, the recapitalization of Holdings, Odyssey's equity investment in Holdings, the issuance of Holdings' pay-in-kind notes, the acquisition of ZMP, Inc. and the related borrowings under the new credit facility as if they had occurred on October 1, 1997, we would have generated net sales, operating income and EBITDA, As Defined, of $145.0 million, $39.3 million and $49.0 million, respectively. For the thirteen weeks ended January 1, 1999 on a pro forma basis as if those transactions had occurred on October 1, 1998, we would have generated net sales, operating income and EBITDA, As Defined, of $37.9 million, $10.3 million and $12.8 million, respectively.

Our business is comprised of four business units: (1) AdelWiggins Group, (2) AeroControlex Group, (3) Marathon Power Technologies Company, and (4) Adams Rite Aerospace, Inc., each of which has a long history in the aircraft components industry. AdelWiggins manufactures an extensive line of fuel and hydraulic system connectors and specialized clamps, heaters and refueling systems. AeroControlex manufactures customized fuel pumps, compressors, valves, couplings and mechanical and electromechanical controls. Marathon manufactures nickel cadmium batteries and static inverters. Adams Rite Aerospace manufactures mechanical hardware, fluid controls, lavatory hardware, electromechanical controls and oxygen systems related products. TransDigm Inc. was formed in 1993 through a management-led buyout of the Aerospace Components Group of IMO Industries Inc. In addition, Marathon and ZMP, Inc., the corporate parent of Adams Rite Aerospace, were acquired in August 1997 and April 1999, respectively, as a strategic complement to the Adelwiggins and AeroControlex businesses.

BUSINESS STRATEGY

Key elements of our strategy are:

- PROVIDE VALUE ADDED PRODUCTS TO CUSTOMERS. We will continue to focus on marketing and manufacturing highly engineered products to customers that place a premium on our capabilities.

- GENERATE NEW BUSINESS INITIATIVES. We intend to continue to aggressively pursue growth opportunities through our new business initiatives, particularly in the aftermarket.

- REALIZE PRODUCTIVITY SAVINGS. We will continue to focus on improving our operating margins through manufacturing improvements and increases in employee productivity.

- PURSUE STRATEGIC ACQUISITIONS. We intend to aggressively pursue acquisitions that we believe will allow us to enhance value, reduce costs and develop new business.

RECENT DEVELOPMENTS

At the same time as the offering of the Old Notes by TransDigm, Holdings consummated a recapitalization. The former equity holders of Holdings received a payment in the recapitalization of $330.0 million of which $279.7 million was paid in cash, $20.0 million was paid in the form of Holdings' pay-in-kind notes and Holdings' common stock and approximately $30.3 million was retained by such equity holders in the form of equity interest in Holdings.

As part of the recapitalization, Odyssey Investment Partners Fund, LLC and its co-investors invested $100.2 million of cash equity in Holdings. As a result of the recapitalization, Odyssey and its co-investors own approximately 73.7%, and certain continuing equity holders of Holdings own approximately 26.3%, in each case, of the outstanding shares of Holdings common stock on a fully diluted basis.

On April 23, 1999, TransDigm acquired ZMP, Inc., the corporate parent of Adams Rite Aerospace, through a merger. The purchase price for the acquisition was $41 million, subject to post-closing purchase price adjustments. The acquisition was funded entirely through additional borrowings under the new credit facility. As a result of the acquisition, ZMP and Adams Rite Aerospace became wholly-owned subsidiaries of TransDigm.

ODYSSEY INVESTMENT PARTNERS FUND, LLC

As a result of the recapitalization, TransDigm is controlled by Odyssey, a private equity fund engaged in making investments in established, middle market companies. Although Odyssey was formed in 1997, its principals collectively have over 70 years of private equity experience.

SUMMARY OF THE TERMS OF THE EXCHANGE OFFER

The Exchange Offer..................  $1,000 principal amount of New Notes in exchange for
                                      each $1,000 principal amount of Old Notes. As of the
                                      date hereof, Old Notes representing $125.0 million
                                      aggregate principal amount are outstanding.

                                      Based on interpretations by the staff of the
                                      Commission, as set forth in no-action letters issued
                                      to certain third parties unrelated to us, we,
                                      together with Holdings, Marathon, ZMP and Adams Rite
                                      Aerospace (together, the "Guarantors"), believe that
                                      New Notes issued pursuant to the exchange offer in
                                      exchange for Old Notes may be offered for resale,
                                      resold or otherwise transferred by you without
                                      compliance with the registration and prospectus
                                      delivery requirements of the Securities Act, unless
                                      you:

                                      - are an "affiliate" of ours or the Guarantors within
                                      the meaning of Rule 405 under the Securities Act;

                                      - are a broker-dealer who purchased Old Notes
                                      directly from us for resale under Rule 144A or any
                                        other available exemption under the Securities Act;

                                      - acquired the New Notes other than in the ordinary
                                        course of your business; or

                                      - have an arrangement with any person to engage in
                                      the distribution of New Notes.

                                      However, the Commission has not considered the
                                      exchange offer in the context of a no-action letter
                                      and we cannot be sure that the staff of the
                                      Commission would make a similar determination with
                                      respect to the exchange offer as in such other
                                      circumstances. Furthermore, you must make the
                                      appropriate representations in the letter of
                                      transmittal that we are sending you with this
                                      prospectus.

Registration Rights Agreement.......  We sold the Old Notes on December 3, 1998, in a
                                      private placement in reliance on Section 4(2) of the
                                      Securities Act. The Old Notes were immediately resold
                                      by the initial purchasers in reliance on Rule 144A
                                      and Regulation S under the Securities Act. At the
                                      same time, we entered into a registration rights
                                      agreement with the initial purchasers requiring us to
                                      make the exchange offer. The registration rights
                                      agreement also requires us and the Guarantors to:

                                      - cause the registration statement filed with respect
                                      to the exchange offer to be declared effective by May
                                        2, 1999; and

                                      - consummate the exchange offer by June 6, 1999.

                                      See "The Exchange Offer--Purpose and Effect." If we
                                      do not do so, the interest rate on the Old Notes will
                                      increase initially by 0.50%.

Expiration Date.....................  The exchange offer will expire at 5:00 p.m., New York
                                      City time,       , 1999 or a later date and time if
                                      we extend it (the "Expiration Date").

Withdrawal..........................  The tender of the Old Notes pursuant to the exchange
                                      offer may be withdrawn at any time prior to the
                                      Expiration Date. Any Old Notes not accepted for
                                      exchange for any reason will be returned without
                                      expense as soon as practicable after the expiration
                                      or termination of the exchange offer.

Interest on the New Notes and the
  Old Notes.........................  Interest on the New Notes will accrue from the date
                                      of the original issuance of the Old Notes or from the
                                      date of the last payment of interest on the Old
                                      Notes, whichever is later. No additional interest
                                      will be paid on the Old Notes tendered and accepted

                                      Offer Program, by which you will agree to be bound by
                                      the letter of transmittal. By executing or agreeing
                                      to be bound by the letter of transmittal, you will be

                                      under "The Exchange Offer--Purpose and Effect."

                                      Under certain circumstances specified in the
                                      registration rights agreement, we may be required to
                                      file a "shelf" registration statement for the Old
                                      Notes for a continuous offering under Rule 415 under
                                      the Securities Act. See "Registration Rights."

                                      We will accept for exchange any and all Old Notes
                                      which are properly tendered in the exchange offer
                                      prior to the Expiration Date. The New Notes issued in
                                      the exchange offer will be delivered promptly
                                      following the Expiration

                                      Date. See "The Exchange Offer--Terms of the Exchange
                                      Offer."

Exchange Agent......................  State Street Bank and Trust Company is serving as
                                      exchange agent (the "Exchange Agent") in connection
                                      with the exchange offer.

Federal Income Tax Considerations...  We believe the exchange of Old Notes for New Notes in
                                      the exchange offer will not constitute a sale or an
                                      exchange for federal income tax purposes. See
                                      "Certain United States Federal Income Tax
                                      Considerations."

Effect of Not Tendering.............  Old Notes that are not tendered or that are tendered
                                      but not accepted will, following the completion of
                                      the exchange offer, continue to be subject to their
                                      existing transfer restrictions. We will have no
                                      further obligation to provide for registration under
                                      the Securities Act of such Old Notes.

SUMMARY OF THE TERMS OF THE NEW NOTES

Securities Offered...........................  $125,000,000 in aggregate principal amount of
                                               senior subordinated notes.

Guarantees...................................  Holdings, the parent holding company of
                                               TransDigm, will fully and unconditionally
                                               guarantee the New Notes. However, you should
                                               not rely upon the guarantee by Holdings
                                               because Holdings has no assets other than its
                                               equity interest in TransDigm. In addition,
                                               our domestic subsidiaries will fully and
                                               unconditionally guarantee the New Notes on a
                                               joint and several basis with Holdings.

                                               If we create or acquire a new domestic
                                               subsidiary, it will guarantee the New Notes
                                               unless we designate the subsidiary as an
                                               "unrestricted subsidiary" under the indenture
                                               or the subsidiary does not have significant
                                               assets.

Ranking......................................  The New Notes will be our unsecured senior
                                               subordinated obligations and will rank junior
                                               to our existing and future senior debt. The
                                               guarantees by Holdings and our subsidiaries
                                               will be subordinated to existing and future
                                               senior debt of Holdings and our subsidiaries,
                                               respectively. As of January 1, 1999 on a pro
                                               forma basis after giving effect to the
                                               acquisition of ZMP and the related borrowings
                                               under the new credit facility as if they had
                                               occurred on January 1, 1999, we and our
                                               subsidiaries would have had $133.0 million of
                                               senior debt, excluding approximately $21.0
                                               million that we would have had available to
                                               borrow under our New Credit Facility, and
                                               Holdings would have had $153.2 million of
                                               senior debt.

Optional Redemption..........................  We cannot redeem the New Notes until December
                                               1, 2003. Thereafter we may redeem some or all
                                               of the New Notes at the redemption prices
                                               listed in the "Description of the New Notes"
                                               section under the heading "Optional
                                               Redemption," plus accrued interest.

Optional Redemption after Public Equity        At any time and from time to time before
  Offerings..................................  December 1, 2001, we can choose to buy back
                                               up to 35% of the outstanding Notes with money
                                               that we raise in certain types of equity
                                               offerings, as long as:

                                               -  we pay 110.375% of the face amount of the
                                                  Notes, plus accrued interest;

                                               -  we buy the Notes back within 120 days of
                                                  completing such equity offering; and

                                               -  at least 65% of the aggregate principal
                                               amount of Notes issued remains outstanding
                                                  afterwards.

Change of Control Offer......................  If a change in control of TransDigm or
                                               Holdings occurs, we may be required to give
                                               holders of the New Notes the opportunity to
                                               sell us their New Notes at 101% of their face
                                               amount, plus accrued interest.

                                               We might not be able to pay you the required
                                               price for New Notes you present to us at the
                                               time of a change of control, because:

                                               -  we might not have enough funds at that
                                                  time; or

                                               -  the terms of our senior debt may prevent
                                               us from paying.

Asset Sale Proceeds..........................  If we engage in asset sales, we generally
                                               must either invest the net cash proceeds from
                                               such sales in our business within a period of
                                               time, repay senior debt or make an offer to
                                               purchase a principal amount of the New Notes
                                               equal to the excess net cash proceeds. The
                                               purchase price of the New Notes will be 100%
                                               of their principal amount, plus accrued
                                               interest.

Certain Indenture Provisions.................  The indenture governing the New Notes will
                                               contain covenants limiting our and most or
                                               all of our subsidiaries' ability to:

                                               These covenants are subject to a number of
                                               important limitations and exceptions.

SUMMARY CONSOLIDATED HISTORICAL AND PRO FORMA FINANCIAL DATA

The following table sets forth summary historical and pro forma consolidated financial information of Holdings. The summary historical consolidated financial data for the fiscal years ended September 30, 1998, 1997, and 1996 have been derived from Holdings' consolidated financial statements, which have been audited by Deloitte & Touche LLP, independent auditors. The summary historical consolidated financial data as of and for the thirteen weeks ended January 1, 1999 and December 26, 1997 has been derived from Holdings' unaudited consolidated financial statements for those periods, which, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results of operations, financial position, and cash flows. The results for the thirteen weeks ended January 1, 1999 are not necessarily indicative of results that may be expected for the entire year. Separate financial information for TransDigm is not presented since the New Notes will be guaranteed by Holdings and all direct and indirect subsidiaries of TransDigm, and since Holdings has no operations or assets separate from its investment in TransDigm.

The pro forma statement of operations data and the pro forma other financial data set forth below give effect to the offering of the Old Notes, the recapitalization of Holdings, Odyssey's equity investment in Holdings, the issuance of Holdings' pay-in-kind notes, the acquisition of ZMP and the related borrowings under the new credit facility as if they had occurred at the beginning of the period. The pro forma balance sheet data set forth below give effect to the acquisition of ZMP and the related borrowings under the new credit facility as if they had occurred as of the balance sheet date. ZMP's fiscal year 1998 ended on June 26, 1998. The pro forma financial information is not necessarily indicative of either future results of operations or the results that might have occurred if the applicable transactions had been consummated on such date. There can be no assurance that assumptions used in the preparation of the pro forma financial data will prove to be correct.

The Marathon Acquisition was completed on August 8, 1997. The acquisition was accounted for as a purchase. The results of operations of Marathon are included in Holdings' consolidated historical financial statements from the date of such acquisition. The acquisition of ZMP will also be accounted for as a purchase.

You should read the following table together with the "Unaudited Pro Forma Consolidated Financial Information" and the "Management's Discussion and Analysis of Financial Condition and Results of Operations" sections and the Consolidated Historical Financial Statements and the notes thereto included elsewhere in this prospectus.

(1) Operating income (loss) includes the effect of a non-cash charge of $666 in fiscal 1997 and $242 in fiscal 1998 due to, in each case, a purchase accounting adjustment to inventory associated with the acquisition of Marathon.

(2) The interest expense reported for fiscal 1996 through 1998 represents interest expense of TransDigm. Holdings had no interest expense prior to the Recapitalization. After the Recapitalization, Holdings has incurred interest expense relating to the Holdings PIK Notes and Holdings has no other interest expense. TransDigm is not an obligor or a guarantor under the Holdings PIK Notes. Pro forma interest expense and historical interest expense for the Holdings PIK Notes for the thirteen weeks ended January 1, 1999 were $600 and $200, respectively. Pro forma EBITDA, As Defined to interest expense of TransDigm, which excludes the Holdings PIK Notes, for fiscal 1998 and the thirteen weeks ended January 1, 1999 was 1.9x and 2.0x, respectively.

(3) EBITDA represents earnings before interest, taxes, depreciation, amortization, warrant put value adjustments and extraordinary items. EBITDA is presented because management believes it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in Holdings' industry. However, other companies in Holdings' industry may calculate EBITDA differently than Holdings does. EBITDA is not a measurement of financial performance under generally accepted accounting principles and should not be considered as an alternative to cash flow from operating activities, as a measure of liquidity or an alternative to net income as indicators of Holdings' operating performance or any other measures of performance derived in accordance with generally accepted accounting principles. See Holdings' Consolidated Statements of Cash Flows included in Holdings consolidated financial statements.

(4) EBITDA, As Defined, is calculated as follows:

                                                                                             THIRTEEN WEEKS ENDED

EBITDA, As Defined, is presented herein to provide additional information with respect to the ability of Holdings to satisfy its debt service, capital expenditure and working capital requirements and because certain types of covenants in TransDigm's and Holdings' borrowing arrangements are tied to similar measures. While EBITDA-based measures are frequently used as measures of operations and the ability to meet debt service requirements, they are not necessarily comparable to other similarly titled captions of other companies due to differences in methods of calculation.

(5) For purposes of computing the ratio of earnings to fixed charges, earnings consist of earnings before income taxes plus fixed charges. Fixed charges consist of interest expense, amortization of debt expense and the portion (approximately 33%) of rental expense that management believes is representative of the interest component of rental expense. Earnings were insufficient to cover fixed charges by $32,390 for the thirteen weeks ended January 1, 1999.

SUBSTANTIAL LEVERAGE--OUR SUBSTANTIAL INDEBTEDNESS COULD ADVERSELY AFFECT OUR FINANCIAL HEALTH AND PREVENT US FROM FULFILLING OUR OBLIGATIONS UNDER THE NEW NOTES.

We have a significant amount of indebtedness. The following chart shows some of our important credit statistics and is presented as at January 1, 1999 on a pro forma basis assuming we had completed the acquisition of ZMP and the related borrowings under the new credit facility as of the date specified below:

Total indebtedness............................................................................      $    258.0

In addition, Holdings has an additional $20.2 million of indebtedness represented by the value of the Holdings' pay-in-kind notes, all of which will be senior to Holdings' guarantee of these New Notes. As at January 1, 1999 on a pro forma basis assuming we had completed the acquisition of ZMP and the related borrowings under the new credit facility on January 1, 1999, Holdings would have had a stockholders' deficit of approximately $136.2 million. See "Unaudited Pro Forma Consolidated Financial Information." Holdings' ratio of earnings to fixed charges for the fiscal year ended September 30, 1998 and the thirteen weeks ended January 1, 1999, in each case, on a pro forma basis assuming we had completed (1) the offering of the Old Notes, (2) the recapitalization of Holdings, (3) Odyssey's equity investment in Holdings, (4) the issuance of Holdings' pay-in-kind notes, (5) the acquisition of ZMP and (6) the related borrowings under the new credit facility at the beginning of the period specified below would have been as follows:

                                                                       HOLDINGS                    HOLDINGS

Ratio of earnings to fixed charges.............................             1.4x                        1.5x

Our substantial indebtedness could have important consequences to you. For example, it could:

- make it more difficult for us to satisfy our obligations with respect to the New Notes;

- increase our vulnerability to general adverse economic and industry conditions;

- limit our ability to fund future working capital, capital expenditures, research and development costs and other general corporate requirements;

11

- require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, research and development efforts and other general corporate purposes;

- limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;

- place us at a competitive disadvantage compared to our competitors that have less debt; and

- limit, along with the financial and other restrictive covenants in our indebtedness, among other things, our ability to borrow additional funds. And, failing to comply with those covenants could result in an event of default which, if not cured or waived, could have a material adverse effect on us.

See "Description of the New Notes" and "Description of Other Indebtedness."

ADDITIONAL BORROWINGS AVAILABLE--DESPITE OUR CURRENT INDEBTEDNESS LEVELS, WE AND OUR SUBSIDIARIES MAY STILL BE ABLE TO INCUR SUBSTANTIALLY MORE DEBT. THIS COULD FURTHER EXACERBATE THE RISKS DESCRIBED ABOVE.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. The terms of the indenture do not fully prohibit us or our subsidiaries from doing so. As at January 1, 1999 on a pro forma basis assuming we had completed the acquisition of ZMP and the related borrowings under the new credit facility on January 1, 1999, our new credit facility would have permitted additional borrowings of up to $21.0 million and all of those borrowings would have been senior to the New Notes and the guarantees of the New Notes. If new debt is added to our and the guarantors' current debt levels, the related risks that we and they now face could intensify.

See "Capitalization," "Selected Historical Consolidated Financial Data" and "Description of the New Notes" and "Description of Other Indebtedness."

ABILITY TO SERVICE DEBT--TO SERVICE OUR INDEBTEDNESS, WE WILL REQUIRE A SIGNIFICANT AMOUNT OF CASH. OUR ABILITY TO GENERATE CASH DEPENDS ON MANY FACTORS BEYOND OUR CONTROL.

Our ability to make payments on and to refinance our indebtedness, including the New Notes, and to fund planned capital expenditures and research and development efforts will depend on our ability to generate cash in the future. This is subject not only to our performance within our industry, but also to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

Based on our current level of operations and anticipated cost savings and revenue growth, we believe our cash flow from operations, available cash and available borrowings under our new credit facility, will be adequate to meet our future liquidity needs for at least the next several years.

We cannot assure you, however, that our business will generate sufficient cash flow from operations, that currently anticipated cost savings and revenue growth will be realized on schedule or at all or that future borrowings will be available to us under our new credit facility in amounts sufficient to enable us to pay our indebtedness, including the New Notes, or to fund our other liquidity needs. We may need to refinance all or a portion of our indebtedness, including the New Notes, on or before maturity. We cannot assure you that we will be able to refinance any of our indebtedness, including our new credit facility and the New Notes, on commercially reasonable terms or at all.

SUBORDINATION--YOUR RIGHT TO RECEIVE PAYMENTS ON THE NEW NOTES IS JUNIOR TO OUR EXISTING INDEBTEDNESS AND POSSIBLY ALL OF OUR FUTURE BORROWINGS. FURTHER, THE GUARANTEES OF THE NEW NOTES WILL BE JUNIOR TO ALL THE GUARANTORS' EXISTING INDEBTEDNESS AND POSSIBLY TO ALL THEIR FUTURE BORROWINGS.

12

The New Notes and the guarantees rank behind all of our and the guarantors' existing indebtedness, other than trade payables, and all of our and all the guarantors' future borrowings, other than trade payables, except any future indebtedness that expressly provides that it ranks equal with, or junior in right of payment to, the New Notes and the guarantees. As a result, upon any distribution to our creditors or the creditors of the guarantors in a bankruptcy, liquidation or reorganization or similar proceeding relating to us or the guarantors or our or their property, the holders of our senior debt and the senior debt of the guarantors will be entitled to be paid in full in cash before any payment may be made with respect to the New Notes or the guarantees.

In addition, all payments on the New Notes and the guarantees will be blocked in the event of a payment default on senior debt and may be blocked for up to 179 of 360 consecutive days in the event of certain non-payment defaults on senior debt.

In the event of a bankruptcy, liquidation or reorganization or similar proceeding relating to us or the guarantors, holders of the New Notes will participate with trade creditors and all other holders of our subordinated indebtedness and the subordinated indebtedness of the guarantors in the assets remaining after we and the guarantors have paid all of the senior debt. However, because the indenture requires that amounts otherwise payable to holders of the New Notes in a bankruptcy or similar proceeding be paid to holders of senior debt instead, holders of the New Notes may receive less, ratably than holders of trade payables in any such proceeding. In any of these cases, we and the guarantors may not have sufficient funds to pay all of our creditors and holders of New Notes may receive less, ratably than the holders of senior debt.

Assuming we had completed the exchange offer, the acquisition of ZMP and the related borrowings under the new credit facility on January 1, 1999, the New Notes and the guarantees by our domestic subsidiary would have been subordinated to $133.0 million of senior debt under our new credit facility. In addition, the new credit facility would have provided for up to approximately $21.0 million of additional borrowings. Holdings' guarantee of the New Notes would have been subordinated to $153.2 million of senior debt consisting of the guarantee of the new credit facility and the value of the Holdings' pay-in-kind notes. We are permitted to borrow substantial additional indebtedness, including senior debt, in the future under the terms of the indenture.

LIMITED VALUE OF HOLDINGS GUARANTEE--YOU SHOULD NOT RELY ON THE GUARANTEE BY

HOLDINGS IN THE EVENT WE CANNOT MAKE PAYMENTS UPON THE NEW NOTES.

The New Notes will be guaranteed by Holdings, our parent holding company, on a senior subordinated basis. You should not rely on this guarantee because Holdings has no assets other than our capital stock. If we cannot make payments under the New Notes, Holdings probably cannot make payments either. In addition, this guarantee will be subordinated to all senior debt of Holdings, which consists of Holdings' guarantee of the borrowings under the new credit facility and the borrowings consisting of the face value of the Holdings' pay-in-kind notes, in each case, whose holders would be paid before you in the event of a liquidation.

DEPENDENCE ON MAJOR CUSTOMERS--WE RELY HEAVILY ON CERTAIN CUSTOMERS FOR MUCH

OF OUR SALES.

Our three largest customers for the fiscal year ended September 30, 1998 were Aviall, a distributor of aftermarket parts to airlines throughout the world, Boeing, which includes McDonnell Douglas and various agencies of the United States government. These customers accounted for approximately 20%, 14% and 9%, respectively, of our consolidated net sales in fiscal 1998.

Our top ten customers accounted for approximately 61% of our consolidated net sales for fiscal 1998.

13

The loss of any one or more of these key customers could have a material adverse effect on our business. See "Business--Customers" and "Management's Discussion and Analysis of Financial Condition and Results of Operations."

CUSTOMER CONTRACTS--WE GENERALLY DO NOT HAVE GUARANTEED FUTURE SALES OF OUR PRODUCTS. FURTHER, WE ARE OBLIGATED UNDER FIXED PRICE CONTRACTS WITH SOME OF OUR CUSTOMERS, SO WE TAKE THE RISK FOR COST OVERRUNS.

Since we do not have long-term contracts with most of our customers, future sales of our products are not guaranteed. Even in those cases where we do, such as with Boeing and the United States government, our customers may terminate these contracts on short notice.

We also have entered into fixed-price contracts with some of our customers, where we agree to perform the work for a fixed price and, accordingly, realize all the benefit or detriment resulting from any decreased or increased costs for making these products. Sometimes we accept a fixed-price contract for a product which we have not yet produced, which increases the risks of delays or cost overruns.

We also have some contracts with customers which establish prices for certain of our components based upon the volume the customer purchases. A number of these contracts do not permit us to recover for increases in input prices, taxes or labor costs. Any such increases without increases in our prices are likely to have an adverse effect on our business and may affect our ability to make payments to you under the New Notes.

AIRCRAFT COMPONENTS INDUSTRY RISKS--OUR BUSINESS IS SENSITIVE TO THE NUMBER OF FLIGHT HOURS THAT OUR CUSTOMERS' PLANES SPEND ALOFT AND TO OUR CUSTOMERS' PROFITABILITY. THESE ITEMS ARE, IN TURN, AFFECTED BY GENERAL ECONOMIC CONDITIONS. IN ADDITION, OUR SALES TO MANUFACTURERS OF NEW LARGE AIRCRAFT ARE CYCLICAL.

We compete in the aircraft component segment of the aerospace industry. This segment is sensitive to changes in the number of miles flown by paying customers of commercial airlines ("revenue passenger miles") and, to a lesser extent, to changes in the profitability of the commercial airline industry and the size and age of the worldwide aircraft fleet.

Revenue passenger miles and airline profitability have historically been correlated with the general economic environment, although international events can also play a key role. For example, in 1991 revenue passenger miles declined as a result of increased security concerns among airline customers following the Gulf War. Although 1991 was the only year in the last ten years in which revenue passenger miles declined, any future reduction would reduce the use of commercial aircraft and, consequently, the need for spare parts and new aircraft. During periods of reduced airline profitability, some airlines may elect to delay purchases of spare parts, preferring instead to deplete existing inventories.

If demand for new aircraft and spare parts decreases, there may be a decrease in demand for certain of our products. Therefore, any future decline in revenue passenger miles, airline profitability or the size of the worldwide aircraft fleet, for any reason, could have a material adverse effect on our business. See "Business--Industry Overview."

In addition, sales to manufacturers of large commercial aircraft, which accounted for less than 20% of our annual net sales in fiscal 1998, have historically experienced periodic downturns. In the past, these sales have been affected by airline profitability, which is impacted by fuel and labor costs and price competition, and other things. Due in part to these factors, the number of large commercial aircraft delivered dropped from a peak of approximately 756 aircraft in 1991 to approximately 370 aircraft in 1995, according to a trade report.

14

We believe that by concentrating on products with strong aftermarket demand and on smaller regional planes, we have reduced our exposure to downturns in this sector. Prior downturns have adversely effected our net sales, gross margin and net income. These and certain other factors may cause a downturn in sales to manufacturers of large commercial aircraft in the future which may have a material adverse effect on our business.

REDUCTION IN DEFENSE SPENDING--A DECLINE IN THE U.S. DEFENSE BUDGET MAY

ADVERSELY AFFECT OUR SALES OF PARTS USED IN MILITARY AIRCRAFT.

In fiscal 1998, approximately 27.0% of our sales were related to products used in military aircraft, in each case, over half of which were spare parts provided to various governmental agencies.

In general, the United States' defense budget has been declining or stable in recent years, resulting in reduced or stable demand for new aircraft and, to a lessor extent, spare parts. The United States' defense budget may continue to decline and sales of defense related items to foreign governments may decrease. If there is a decline which reduces demand for our components, our business may be adversely affected.

GOVERNMENT REGULATION--OUR BUSINESS WOULD BE ADVERSELY AFFECTED IF WE LOST OUR GOVERNMENT PERMITS OR IF FUTURE, MORE ONEROUS GOVERNMENT REGULATIONS WERE ENACTED.

In order to sell our components, our company and the components we manufacture must be certified by the FAA, the United States Department of Defense and similar agencies in foreign countries and by individual manufacturers.

If material authorizations or approvals were revoked or suspended, our business would be adversely affected. In the future, if new and more stringent government regulations are adopted or if industry oversight increases, our business may be adversely affected. See "Business--Governmental Regulation."

RISKS ASSOCIATED WITH OUR WORKFORCE--WE ARE DEPENDENT ON OUR HIGHLY TRAINED EMPLOYEES AND ANY WORK STOPPAGE OR DIFFICULTY HIRING SIMILAR EMPLOYEES WOULD ADVERSELY AFFECT OUR BUSINESS.

Because our products are complicated and very detailed, we are highly dependent on an educated and trained workforce. There is substantial competition for these kinds of personnel in the aircraft component industry. We may not be able to (1) retain our existing senior management or engineering staff, (2) fill new positions or vacancies created by expansion or turnover, or (3) attract additional qualified personnel. Although we have entered into employment agreements with certain executive officers, these agreements may not be renewed. See "Management--Employment Agreements."

At September 30, 1998, approximately 30% of our employees were unionized. Our collective bargaining agreements expire in April 2002 and November 2000. Although we believe that our relations with our employees are good, we cannot assure you that we will be able to negotiate a satisfactory renewal of these collective bargaining agreements or that our employee relations will remain stable.

Because we maintain a relatively small inventory of finished goods and operate on relatively short lead times for our products, any work shortage or shortage in skilled employees could have a material adverse effect on our business. "See Business--Employees."

RISKS ASSOCIATED WITH SUPPLIERS--OUR BUSINESS IS DEPENDENT ON THE

AVAILABILITY OF CERTAIN COMPONENTS AND RAW MATERIALS THAT WE BUY FROM SUPPLIERS.

Our business is affected by the price and availability of the raw materials and unique component parts that we use to manufacture our components. Because we maintain a relatively small inventory of raw materials and component parts, our business could be adversely affected by factors affecting our

15

suppliers, or by increased costs of such raw materials or components if we are unable to pass along such price increases to our customers. See "Business--Raw Materials and Patents."

POTENTIAL EXPOSURE TO ENVIRONMENTAL LIABILITIES--WE MAY BE LIABLE FOR PENALTIES UNDER A VARIETY OF ENVIRONMENTAL LAWS, EVEN IF WE DID NOT CAUSE ANY ENVIRONMENTAL PROBLEMS. CHANGES IN ENVIRONMENTAL LAWS OR UNEXPECTED INVESTIGATIONS COULD ADVERSELY AFFECT OUR BUSINESS.

Our business and our facilities are subject to a number of federal, state and local laws and regulations, which govern, among other things, the discharge of hazardous materials into the air and water as well as the handling, storage and disposal of such materials.

Pursuant to certain environmental laws, a current or previous owner or operator of land or persons who arrange (as defined under these statutes) for the disposal or treatment of hazardous materials may be liable for the costs of investigation, removal or remediation of hazardous materials at such property. These laws typically impose liability whether or not the owner or operator knew of, or was responsible for, the presence of any hazardous materials. See "Business--Environmental Matters."

Because we own and operate a number of facilities, and because we arrange for the disposal of hazardous materials at many disposal sites, we may incur costs for investigation, removal and remediation, as well as capital costs associated with compliance with these laws. Although such environmental costs have not been material in the past and are not expected to be material in the future, changes in environmental laws or unexpected investigations and clean-up costs could have a material adverse effect on our business.

RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS AND ASIAN FINANCIAL MARKETS--OUR INTERNATIONAL BUSINESS EXPOSES US TO RISKS RELATING TO INCREASED REGULATION AND POLITICAL OR ECONOMIC INSTABILITY, GLOBALLY OR WITHIN CERTAIN FOREIGN COUNTRIES.

Approximately 16%, 20% and 20% of our sales in fiscal 1998, fiscal 1997 and fiscal 1996, respectively, were made directly to foreign end-users. In addition, a portion of the products we sell to domestic distributors are resold to foreign end-users. These sales are subject to numerous additional risks, including the impact of foreign government regulations, currency fluctuations, political uncertainties and differences in business practices.

Foreign governments could adopt regulations or take other actions that would have an adverse impact on our business or market opportunities abroad. Furthermore, the political, cultural and economic climate outside the United States may not be favorable to our business and growth strategy.

The Asian markets are important markets for airlines and the large commercial aircraft manufacturers. For example, Boeing has developed a large backlog of aircraft sales to customers in Asia, and the current crisis in the Asian financial markets has resulted in some deferrals and cancellations of deliveries. This may result in significant cancellation of orders or additional deferral of deliveries for new aircraft or negatively impact these manufacturers. The resulting decreased demand in the aftermarket could adversely affect our business.

RISKS RELATED TO CURRENT AND POTENTIAL FUTURE ACQUISITIONS--WE INTEND TO PURSUE FUTURE ACQUISITIONS AND ARE CONSIDERING A SPECIFIC ACQUISITION WHICH, IF CONSUMMATED, WOULD SUBSTANTIALLY INCREASE THE LEVEL OF OUR INDEBTEDNESS AND MAY ADVERSELY AFFECT OUR BUSINESS IF WE CANNOT EFFECTIVELY INTEGRATE THESE NEW OPERATIONS.

On April 23, 1999, we acquired ZMP, Inc., the corporate parent of Adams Rite Aerospace, through a merger. The purchase price for the acquisition was $41 million, subject to post-closing purchase price adjustments. The acquisition was funded entirely through additional borrowings under the new credit facility. We intend to pursue additional acquisitions that we believe will present

16

opportunities to realize significant synergies, operating expense reductions or overhead cost savings and increase our market position. This acquisition strategy may require substantial capital, and we may not be able to raise the necessary funds on satisfactory terms or at all. Although we currently have no binding agreements with respect to any additional acquisitions and we cannot assure you that we will be able to reach agreement with respect to any additional acquisition, such acquisitions would likely result in the incurrence of debt and contingent liabilities and an increase in interest expense and amortization expenses related to goodwill and other intangible assets, which could have a material adverse effect upon our business.

Acquisitions involve numerous risks, including difficulties in the assimilation of the operations, technologies, services and products of the acquired companies and the diversion of management's attention from other business concerns. For all of these reasons, if any such acquisitions occur, our business could be adversely affected. In addition, if we are unable to successfully assimilate the operations, technologies, services and products of Adams Rite Aerospace with that of our other three divisions or if the assimilation of Adams Rite Aerospace materially diverts the management's attention from other business concerns, our business could be adversely affected.

COMPETITION--WE MAY BE UNABLE TO REPAY THE NEW NOTES IF WE DO NOT

SUCCESSFULLY COMPETE WITHIN OUR INDUSTRY.

We compete against a number of companies, including divisions of larger companies, some of which have significantly greater financial, technological and marketing resources than us. We also compete for a limited number of customers. We believe that our ability to compete depends on product performance, short lead-time and timely delivery, competitive pricing, responsiveness to our customers and continued certification under customer quality requirements and assurance programs. If we do not retain an advantage vis a vis our competitors in these areas, our business may be adversely affected. See "Business--Competition."

CONTROL BY ODYSSEY--WE ARE CONTROLLED BY ODYSSEY, WHOSE INTERESTS MAY NOT BE

ALIGNED WITH YOURS.

Odyssey and its co-investors indirectly own approximately 73.7% of the equity interests in our parent company, Holdings, on a fully diluted basis and, therefore, have the power, subject to certain exceptions, to control Holdings. They also control the appointment of management and the entering into of mergers, sales of substantially all assets and other extraordinary transactions. The interests of Odyssey may not in all cases be aligned with yours. See "The Transactions" and "Certain Relationships and Related Transactions."

IMPACT OF YEAR 2000 ISSUE--THE YEAR 2000 PROBLEM MAY RESULT IN DECREASED SALES FOR US IF CERTIFICATIONS WE RECEIVED FROM OUR VENDORS ARE INACCURATE OR IF OUR CUSTOMERS AND SUPPLIERS DO NOT ADEQUATELY ADDRESS THEIR YEAR 2000 CONCERNS.

We are completing a review of our information technology systems and embedded systems in order to assess our exposure to Year 2000 issues. For details of this review see "Management's Discussion and Analysis of Financial Condition and Results of Operation--Impact of Year 2000 Issue."

In the event that Year 2000 problems arise for us, or that our significant suppliers or customers, including various agencies of the United States government, do not successfully and timely achieve Year 2000 compliance, we may have to bear Year 2000 costs and expenses which could have a material adverse effect on our business.

PRODUCT LIABILITY; CLAIMS EXPOSURE--WE COULD BE ADVERSELY AFFECTED AS A RESULT OF A LAWSUIT IF ONE OF OUR COMPONENTS CAUSES AN AIRCRAFT TO CRASH AND WE ARE NOT COVERED BY OUR INSURANCE POLICIES.

17

Our operations expose us to potential liabilities for personal injury or death as a result of the failure of an aircraft component that has been designed, manufactured or serviced by us. While management believes that our liability insurance is adequate to protect us from future products liability claims, if claims were to arise, such insurance coverage may not be adequate.

Additionally insurance coverage may not be able to be maintained in the future at an acceptable cost. Any such liability not covered by insurance or for which third party indemnification is not available could have a material adverse effect on our business.

FINANCING CHANGE OF CONTROL OFFER--WE MAY NOT HAVE THE ABILITY TO RAISE THE FUNDS NECESSARY TO FINANCE THE CHANGE OF CONTROL OFFER REQUIRED BY THE INDENTURE.

Upon the occurrence of certain specific kinds of change of control events, we will be required to offer to repurchase all outstanding Notes. However, it is possible that we will not have sufficient funds at the time of the change of control to make the required repurchase of Notes or that restrictions in our new credit facility will not allow such repurchases. In addition, certain important corporate events, such as leveraged recapitalizations that would increase the level of our indebtedness, would not constitute a "Change of Control" under the indenture. See "Description of the New Notes-Change of Control."

FAILURE TO EXCHANGE OLD NOTES--IF YOU DO NOT PROPERLY TENDER YOUR OLD NOTES, YOU WILL CONTINUE TO HOLD UNREGISTERED OLD NOTES AND YOUR ABILITY TO TRANSFER OLD NOTES WILL BE ADVERSELY AFFECTED.

We will only issue New Notes in exchange for Old Notes that are timely received by the Exchange Agent together with all required documents, including a properly completed and signed letter of transmittal. Therefore, you should allow sufficient time to ensure timely delivery of the Old Notes and you should carefully follow the instructions on how to tender your Old Notes. Neither we nor the Exchange Agent are required to tell you of any defects or irregularities with respect to your tender of the Old Notes. If you do not tender your Old Notes or if we do not accept your Old Notes because you did not tender your Old Notes properly, then, after we consummate the exchange offer, you may continue to hold Old Notes that are subject to the existing transfer restrictions. In addition, if you tender your Old Notes for the purpose of participating in a distribution of the New Notes, you will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale of the New Notes. If you are a broker-dealer that receives New Notes for your own account in exchange for Old Notes that you acquired as a result of market-making activities or any other trading activities, you will be required to acknowledge that you will deliver a prospectus in connection with any resale of such New Notes. After the exchange offer is consummated, if you continue to hold any Old Notes, you may have difficulty selling them because there will be less Old Notes outstanding. In addition, if a large amount of Old Notes are not tendered or are tendered improperly, the limited amount of New Notes that would be issued and outstanding after we consummate the exchange offer could lower the market price of such New Notes.

FRAUDULENT CONVEYANCE MATTERS--FEDERAL AND STATE STATUTES ALLOW COURTS, UNDER SPECIFIC CIRCUMSTANCES, TO VOID THE NEW NOTES AND THE GUARANTEES AND REQUIRE NOTEHOLDERS TO RETURN PAYMENTS RECEIVED FROM US OR THE GUARANTORS.

Under the federal bankruptcy law and comparable provisions of state fraudulent transfer laws, the New Notes and the guarantees could be voided, or claims in respect of the New Notes or the guarantees could be subordinated to all of our other debts or debts of any guarantor if, among other things, we or that guarantor, at the time it incurred the indebtedness evidenced by the New Notes or its guarantee:

- received less than reasonably equivalent value or fair consideration for the incurrence of such indebtedness; or

18

- was insolvent or rendered insolvent by reason of such incurrence; or

- was engaged in a business or transaction for which our or that guarantor's remaining assets constituted unreasonably small capital; or

- intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature.

In addition, any payment by us or that guarantor pursuant to the New Notes or a guarantee could be voided and required to be returned to us or that guarantor, or to a fund for the benefit of the creditors of us or that guarantor.

The measures of insolvency for purposes of these fraudulent transfer laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. Generally, however, we or a guarantor would be considered insolvent if:

- the sum of its debts, including contingent liabilities, were greater than the fair saleable value of all of its assets,

- if the present fair saleable value of its assets were less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature, or

- it could not pay its debts as they become due.

Based upon information currently available to us, we believe that the New Notes and the guarantees are being incurred for proper purposes and in good faith and that we, and each of the guarantors:

- are solvent and will continue to be solvent after giving effect to the issuance of the New Notes and the guarantees, as the case may be;

- will have enough capital for carrying on our business and the business of each of the guarantors after the issuance of the New Notes and the guarantees, as the case may be; and

- will be able to pay our debts.

NO PRIOR MARKET FOR THE NEW NOTES--YOU CANNOT BE SURE THAT AN ACTIVE TRADING

MARKET WILL DEVELOP FOR THE NEW NOTES.

The New Notes are a new issue of securities with no established trading market and will not be listed on any securities exchange. The liquidity of the trading market in the New Notes, and the market price quoted for the New Notes, may be adversely affected by changes in the overall market for high yield securities and by changes in our financial performance or prospects or in the prospects for companies in our industry generally. As a result, you cannot be sure that an active trading market will develop for the New Notes.

TRANSACTIONS

On April 23, 1999, TransDigm acquired ZMP, Inc., the corporate parent of Adams Rite Aerospace, Inc., under the terms of an agreement and plan of reorganization, dated March 31, 1999. The purchase price for the acquisition of ZMP was $41 million, subject to post-closing purchase price adjustments. The acquisition of ZMP and the related expenses were funded entirely through additional borrowings under the New Credit Facility.

On December 3, 1998, together with the completion of the offering of the Old Notes by TransDigm, Holdings consummated a recapitalization of Holdings (the "Recapitalization") under the terms of an agreement and plan of merger, dated August 3, 1998, as amended, between Phase II Acquisition Corp. and Holdings (the "Merger Agreement"). Concurrently with the offering of the Old Notes, TransDigm entered into a credit agreement (as amended, the "New Credit Facility") providing for a six-year $30.0 million revolving credit facility (the "Revolving Credit Facility"), $2.6 million of which was funded to consummate the Recapitalization and $8.0 million of which was funded to consummate the acquisition of ZMP, and a 6-year $62.0 million Tranche A Term Loan Facility (the "Tranche A Facility") and a 7 1/2-year $62.0 million Tranche B Term Loan Facility (the "Tranche B Facility"), in each case, $45.0 million of which was funded to consummate the Recapitalization and $17.0 million of which was funded to consummate the acquisition of ZMP. Additional borrowings under the Revolving Credit Facility are available for certain permitted acquisitions and for general corporate purposes, including working capital requirements. See "Description of Other Indebtedness--The Company--The New Credit Facility."

As part of the Recapitalization, Odyssey and its co-investors invested approximately $100.2 million of cash equity in Holdings (the "Odyssey Investment"). The equity holders of Holdings received a payment in the Recapitalization of $330.0 million of which $279.7 million was paid in cash, $20.0 million was paid in the form of Holdings' pay-in-kind notes due 2009 of Holdings (the "Holdings PIK Notes") and Holdings' common stock and $30.3 million was paid in the form of common stock and options of Holdings that was retained by the shareholders of Holdings (the "Rollover Investment"). As a result of the consummation of the Recapitalization, Odyssey and its co-investors own approximately 73.7%, and certain continuing equity holders of Holdings own approximately 26.3%, in each case, of the outstanding shares of Holdings common stock on a fully diluted basis.

The offering of the Old Notes, the Recapitalization, the Odyssey Investment, the issuance of the Holdings PIK Notes, the acquisition of ZMP and the related borrowings under the New Credit Facility are collectively referred to herein as the "Transactions."

THE EXCHANGE OFFER

PURPOSE AND EFFECT

Together with the sale by TransDigm of the Old Notes on December 3, 1998, TransDigm, Holdings and Marathon (together with Holdings, the "Initial Guarantors") entered into a registration rights agreement (the "Registration Rights Agreement"), dated December 3, 1998, with the initial purchasers, which requires that TransDigm and the Initial Guarantors file a registration statement under the Securities Act with respect to the New Notes (the "Registration Statement") and, upon the effectiveness of that Registration Statement, offer to the holders of the Old Notes the opportunity to exchange their Old Notes for a like principal amount of New Notes. The New Notes will be issued without a restrictive legend and generally may be reoffered and resold by the holder without registration under the Securities Act. The Registration Rights Agreement further provides that TransDigm must cause the Registration Statement with respect to the exchange offer to be declared effective by May 2, 1999 and consummate the exchange offer by June 6, 1999.

Except for exceptions listed below, upon the completion of the exchange offer, TransDigm's obligations with respect to the registration of the Old Notes and the New Notes will terminate. A copy of the Registration Rights Agreement has been filed as an exhibit to the Registration Statement, of which this prospectus is a part, and this summary of the material provisions of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the complete Registration Rights Agreement. As a result of the timely filing and the effectiveness of the Registration Statement, TransDigm will not have to pay certain additional interest on the Old Notes provided in the Registration Rights Agreement. Following the completion of the exchange offer, holders of Old Notes not tendered will not have any further registration rights other than as set forth in the paragraphs below, and those Old Notes will continue to be subject to certain restrictions on transfer. Accordingly, the liquidity of the market for the Old Notes could be adversely affected upon consummation of the exchange offer.

In order to participate in the exchange offer, a holder must represent to TransDigm, among other things, that:

- the New Notes acquired pursuant to the exchange offer are being obtained in the ordinary course of business of the holder;

- the holder is not engaging in and does not intend to engage in a distribution of the New Notes;

- the holder does not have an arrangement or understanding with any person to participate in the distribution of the New Notes; and

- the holder is not an "affiliate," as defined under Rule 405 under the Securities Act, of TransDigm or the Guarantors.

Under certain circumstances specified in the Registration Rights Agreement, TransDigm may be required to file a "shelf" registration statement for a continuous offering pursuant to Rule 415 under the Securities Act in respect of the Old Notes. See "--Procedure for Tendering" and "Registration Rights."

Based on an interpretation by the Commission's staff set forth in no-action letters issued to third parties unrelated to TransDigm, TransDigm believes that, with the exceptions set forth below, New Notes issued in the exchange offer may be offered for resale, resold and otherwise transferred by the holder of New Note without compliance with the registration and prospectus delivery requirements of the Securities Act, unless the holder:

- is an "affiliate" of TransDigm or the Guarantors within the meaning of Rule 405 under the Securities Act;

21

- is a broker-dealer who purchased Old Notes directly from TransDigm for resale under Rule 144A or any other available exemption under the Securities Act;

- acquired the New Notes other than in the ordinary course of the holder's business; or

- the holder has an arrangement with any person to engage in the distribution of New Notes.

Any holder who tenders in the exchange offer for the purpose of participating in a distribution of the New Notes cannot rely on this interpretation by the Commission's staff and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction. Each broker-dealer that receives New Notes for its own account in exchange for Old Notes, where such Old Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such New Notes. See "Plan of Distribution." Broker-dealers who acquired Old Notes directly from us and not as a result of market-making activities or other trading activities may not rely on the staff's interpretations discussed above or participate in the exchange offer and must comply with the prospectus delivery requirements of the Securities Act in order to sell the Old Notes.

TERMS OF THE EXCHANGE OFFER

Upon the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal, TransDigm will accept any and all Old Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on , 1999, or such date and time to which we extend the offer. TransDigm will issue $1,000 principal amount of New Notes in exchange for each $1,000 principal amount of outstanding Old Notes accepted in the exchange offer. Holders may tender some or all of their Old Notes pursuant to the exchange offer. However, Old Notes may be tendered only in integral multiples of $1,000 in principal amount.

The New Notes will evidence the same debt as the Old Notes and will be issued under the terms of, and entitled to the benefits of, the Indenture relating to the Old Notes.

As of the date of this prospectus, Old Notes representing $125.0 million aggregate principal amount were outstanding and there was one registered holder, a nominee of DTC. This prospectus, together with the letter of transmittal, is being sent to such registered holder and to others believed to have beneficial interests in the Old Notes. TransDigm intends to conduct the exchange offer in accordance with the applicable requirements of the Exchange Act and the rules and regulations of the Commission promulgated under the Exchange Act.

TransDigm shall be deemed to have accepted validly tendered Old Notes when, as, and if TransDigm has given oral or written notice thereof to the Exchange Agent. The Exchange Agent will act as agent for the tendering holders for the purpose of receiving the New Notes from TransDigm. If any tendered Old Notes are not accepted for exchange because of an invalid tender, the occurrence of certain other events set forth under the heading "--Conditions to the Exchange Offer" or otherwise, certificates for any such unaccepted Old Notes will be returned, without expense, to the tendering holder of those Old Notes as promptly as practicable after , 1999, unless the exchange offer is extended.

Holders who tender Old Notes in the exchange offer will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes with respect to the exchange of Old Notes in the exchange offer. TransDigm will pay all charges and expenses, other than certain applicable taxes, applicable to the exchange offer. See "--Fees and Expenses."

EXPIRATION DATE; EXTENSIONS; AMENDMENTS

The expiration date shall be 5:00 p.m., New York City time, on , 1999, unless TransDigm, in its sole discretion, extends the exchange offer, in which case the expiration date shall mean the latest

22

date and time to which the exchange offer is extended. In order to extend the exchange offer, TransDigm will notify the Exchange Agent and each registered holder of any extension by oral or written notice prior to 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date. TransDigm reserves the right, in its sole discretion, (A) to delay accepting any Old Notes, to extend the exchange offer or, if any of the conditions set forth under "--Conditions to Exchange Offer" shall not have been satisfied, to terminate the exchange offer, by giving oral or written notice of that delay, extension or termination to the Exchange Agent, or (B) to amend the terms of the exchange offer in any manner. In the event that TransDigm makes a material or fundamental change to the terms of the exchange offer, TransDigm will file a post-effective amendment to the Registration Statement.

PROCEDURES FOR TENDERING

Only a holder of Old Notes may tender the Old Notes in the exchange offer. Except as set forth under "--Book Entry Transfer," to tender in the exchange offer a holder must complete, sign, and date the letter of transmittal, or a copy of the letter of transmittal, have the signatures on the letter of transmittal guaranteed if required by the letter of transmittal, and mail or otherwise deliver the letter of transmittal or copy to the Exchange Agent prior to the expiration date. In addition:

- certificates for the Old Notes must be received by the Exchange Agent along with the letter of transmittal prior to the expiration date;

- a timely confirmation of a book-entry transfer (a "Book-Entry Confirmation") of the Old Notes, if that procedure is available, into the Exchange Agent's account at DTC (the "Book-Entry Transfer Facility") following the procedure for book-entry transfer described below, must be received by the Exchange Agent prior to the expiration date; or

- you must comply with the guaranteed delivery procedures described below.

To be tendered effectively, the letter of transmittal and other required documents must be received by the Exchange Agent at the address set forth under "--Exchange Agent" prior to the expiration date.

Your tender, if not withdrawn before the expiration date will constitute an agreement between you and TransDigm in accordance with the terms and subject to the conditions set forth herein and in the letter of transmittal.

THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF TRANSMITTAL AND ALL

OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT YOUR ELECTION AND RISK. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT YOU USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO TRANSDIGM. YOU MAY REQUEST YOUR BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THESE TRANSACTIONS FOR YOU.

Any beneficial owner whose Old Notes are registered in the name of a broker, dealer, commercial bank, trust company, or other nominee and who wishes to tender should contact the registered holder promptly and instruct the registered holder to tender on the beneficial owner's behalf. If the beneficial owner wishes to tender on the owner's own behalf, the owner must, prior to completing and executing the letter of transmittal and delivering the owner's Old Notes, either make appropriate arrangements to register ownership of the Old Notes in the beneficial owner's name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time.

Signatures on a letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed by an "eligible guarantor institution" within the meaning of Rule 17Ad-15 under the Exchange Act (an "Eligible Institution") unless Old Notes tendered pursuant thereto are tendered (A) by a registered holder who has not completed the box entitled "Special Registration Instruction" or "Special Delivery Instructions" on the letter of transmittal or (B) for the account of an Eligible Institution. If signatures on a letter of transmittal or a notice of withdrawal, as the case may be, are

23

required to be guaranteed, the guarantee must be by any eligible guarantor institution that is a member of or participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program or an Eligible Institution.

If the letter of transmittal is signed by a person other than the registered holder of any Old Notes listed in the letter of transmittal, the Old Notes must be endorsed or accompanied by a properly completed bond power, signed by the registered holder as that registered holder's name appears on the Old Notes.

If the letter of transmittal or any Old Notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations, or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and evidence satisfactory to TransDigm of their authority to so act must be submitted with the letter of transmittal unless waived by TransDigm.

All questions as to the validity, form, eligibility, including time of receipt, acceptance, and withdrawal of tendered Old Notes will be determined by TransDigm in its sole discretion, which determination will be final and binding. TransDigm reserves the absolute right to reject any and all Old Notes not properly tendered or any Old Notes TransDigm's acceptance of which would, in the opinion of counsel for TransDigm, be unlawful. TransDigm also reserves the right to waive any defects, irregularities or conditions of tender as to particular Old Notes. TransDigm's interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Old Notes must be cured within such time as TransDigm shall determine. Although TransDigm intends to notify holders of defects or irregularities with respect to tenders of Old Notes, neither TransDigm, the Exchange Agent, nor any other person shall incur any liability for failure to give that notification. Tenders of Old Notes will not be deemed to have been made until such defects or irregularities have been cured or waived. Any Old Notes received by the Exchange Agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned by the Exchange Agent to the tendering holders, unless otherwise provided in the letter of transmittal, as soon as practicable following , 1999, unless the exchange offer is extended.

In addition, TransDigm reserves the right in its sole discretion to purchase or make offers for any Old Notes that remain outstanding after the expiration date or, as set forth under "--Conditions to the exchange offer," to terminate the exchange offer and, to the extent permitted by applicable law, purchase Old Notes in the open market, in privately negotiated transactions, or otherwise. The terms of any such purchases or offers could differ from the terms of the exchange offer.

By tendering, you will represent to TransDigm that, among other things:

- the New Notes acquired in the exchange offer are being obtained in the ordinary course of business of the person receiving such New Notes, whether or not such person is the registered holder;

- you are not engaging in and do not intend to engage in a distribution of the New Notes;

- you do not have an arrangement or understanding with any person to participate in the distribution of such New Notes; and

- you are not an "affiliate," as defined under Rule 405 of the Securities Act, of TransDigm or any of the Guarantors.

In all cases, issuance of New Notes for Old Notes that are accepted for exchange in the exchange offer will be made only after timely receipt by the Exchange Agent of certificates for such Old Notes or a timely Book-Entry Confirmation of such Old Notes into the Exchange Agent's account at the Book-Entry Transfer Facility, a properly completed and duly executed letter of transmittal or, with respect to the DTC and its participants, electronic instructions in which the tendering holder acknowledges its receipt of and agreement to be bound by the letter of transmittal, and all other

24

required documents. If any tendered Old Notes are not accepted for any reason set forth in the terms and conditions of the exchange offer or if Old Notes are submitted for a greater principal amount than the holder desires to exchange, such unaccepted or non-exchanged Old Notes will be returned without expense to the tendering holder or, in the case of Old Notes tendered by book-entry transfer into the Exchange Agent's account at the Book-Entry Transfer Facility according to the book-entry transfer procedures described below, those nonexchanged Old Notes will be credited to an account maintained with that Book-Entry Transfer Facility, in each case, as promptly as practicable after the expiration or termination of the exchange offer.

Each broker-dealer that receives New Notes for its own account in exchange for Old Notes, where those Old Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of those New Notes. See "Plan of Distribution."

BOOK-ENTRY TRANSFER

The Exchange Agent will make a request to establish an account with respect to the Old Notes at the Book-Entry Transfer Facility for purposes of the exchange offer within two business days after the date of this Prospectus, and any financial institution that is a participant in the Book-Entry Transfer Facility's systems may make book-entry delivery of Old Notes being tendered by causing the Book-Entry Transfer Facility to transfer such Old Notes into the Exchange Agent's account at the Book-Entry Transfer Facility in accordance with that Book-Entry Transfer Facility's procedures for transfer. However, although delivery of Old Notes may be effected through book-entry transfer at the Book-Entry Transfer Facility, the letter of transmittal or copy of the letter of transmittal, with any required signature guarantees and any other required documents, must, in any case other than as set forth in the following paragraph, be transmitted to and received by the Exchange Agent at the address set forth under "--Exchange Agent" on or prior to the expiration date or the guaranteed delivery procedures described below must be complied with.

DTC's Automated Tender Offer Program ("ATOP") is the only method of processing exchange offers through DTC. To accept the exchange offer through ATOP, participants in DTC must send electronic instructions to DTC through DTC's communication system instead of sending a signed, hard copy letter of transmittal. DTC is obligated to communicate those electronic instructions to the Exchange Agent. To tender Old Notes through ATOP, the electronic instructions sent to DTC and transmitted by DTC to the Exchange Agent must contain the character by which the participant acknowledges its receipt of and agrees to be bound by the letter of transmittal.

GUARANTEED DELIVERY PROCEDURES

If a registered holder of the Old Notes desires to tender Old Notes and the Old Notes are not immediately available, or time will not permit that holder's Old Notes or other required documents to reach the Exchange Agent before the expiration date, or the procedure for book-entry transfer cannot be completed on a timely basis, a tender may be effected if:

- the tender is made through an Eligible Institution;

- prior to the expiration date, the Exchange Agent receives from that Eligible Institution a properly completed and duly executed letter of transmittal or a facsimile of duly executed letter of transmittal and notice of guaranteed delivery, substantially in the form provided by TransDigm, by telegram, telex, fax transmission, mail or hand delivery, setting forth the name and address of the holder of Old Notes and the amount of Old Notes tendered and stating that the tender is being made by guaranteed delivery and guaranteeing that within three New York Stock Exchange, Inc. ("NYSE") trading days after the date of execution of the notice of guaranteed delivery, the certificates for all physically tendered Old Notes, in proper form for transfer, or a Book-Entry Confirmation, as the case may be, will be deposited by the Eligible Institution with the Exchange Agent; and

25

- the certificates for all physically tendered Old Notes, in proper form for transfer, or a Book-Entry Confirmation, as the case may be, are received by the Exchange Agent within three NYSE trading days after the date of execution of the notice of guaranteed delivery.

WITHDRAWAL RIGHTS

Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on the expiration date.

For a withdrawal of a tender of Old Notes to be effective, a written or, for DTC participants, electronic ATOP transmission notice of withdrawal, must be received by the Exchange Agent at its address set forth under "--Exchange Agent" prior to 5:00 p.m., New York City time, on the expiration date. Any such notice of withdrawal must:

- specify the name of the person having deposited the Old Notes to be withdrawn (the "Depositor");

- identify the Old Notes to be withdrawn, including the certificate number or numbers and principal amount of such Old Notes;

- be signed by the holder in the same manner as the original signature on the letter of transmittal by which such Old Notes were tendered, including any required signature guarantees, or be accompanied by documents of transfer sufficient to have the Trustee register the transfer of such Old Notes into the name of the person withdrawing the tender; and

- specify the name in which any such Old Notes are to be registered, if different from that of the Depositor.

All questions as to the validity, form, eligibility and time of receipt of such notices will be determined by TransDigm, whose determination shall be final and binding on all parties. Any Old Notes so withdrawn will be deemed not to have been validly tendered for exchange for purposes of the exchange offer. Any Old Notes which have been tendered for exchange but which are not exchanged for any reason will be returned to the holder of those Old Notes without cost to that holder as soon as practicable after withdrawal, rejection of tender, or termination of the exchange offer. Properly withdrawn Old Notes may be retendered by following one of the procedures under "--Procedures for Tendering" at any time on or prior to the expiration date.

CONDITIONS TO THE EXCHANGE OFFER

Notwithstanding any other provision of the exchange offer, TransDigm shall not be required to accept for exchange, or to issue New Notes in exchange for, any Old Notes and may terminate or amend the exchange offer if at any time before the acceptance of those Old Notes for exchange or the exchange of the New Notes for those Old Notes, TransDigm determines that the exchange offer violates applicable law, any applicable interpretation of the staff of the Commission or any order of any governmental agency or court of competent jurisdiction.

The foregoing conditions are for the sole benefit of TransDigm and may be asserted by TransDigm regardless of the circumstances giving rise to any such condition or may be waived by TransDigm in whole or in part at any time and from time to time in its sole discretion. The failure by TransDigm at any time to exercise any of the foregoing rights shall not be deemed a waiver of any of those rights and each of those rights shall be deemed an ongoing right which may be asserted at any time and from time to time.

In addition, TransDigm will not accept for exchange any Old Notes tendered, and no New Notes will be issued in exchange for those Old Notes, if at such time any stop order shall be threatened or in effect with respect to the Registration Statement of which this Prospectus constitutes a part or the qualification of the Indenture under the Trust Indenture Act of 1939. In any of those events TransDigm

26

is required to use every reasonable effort to obtain the withdrawal of any stop order at the earliest possible time.

FEES AND EXPENSES

TransDigm will not make any payments to brokers, dealers or others soliciting acceptances of the exchange offer. The principal solicitation is being made by mail; however, additional solicitations may be made in person or by telephone by officers and employees of TransDigm. The estimated cash expenses to be incurred in connection with the exchange offer will be paid by TransDigm and will include fees and expenses of the Exchange Agent, accounting, legal, printing, and related fees and expenses.

TRANSFER TAXES

Holders who tender their Old Notes for exchange will not be obligated to pay any transfer taxes in connection with that tender or exchange, except that holders who instruct TransDigm to register New Notes in the name of, or request that Old Notes not tendered or not accepted in the exchange offer be returned to, a person other than the registered tendering holder will be responsible for the payment of any applicable transfer tax on those Old Notes.

27

USE OF PROCEEDS

TransDigm will not receive any cash proceeds from the issuance of the New Notes. In consideration for issuing the New Notes as contemplated in this prospectus, TransDigm will receive in exchange Old Notes in like principal amount, which will be canceled and as such will not result in any increase in our indebtedness.

CAPITALIZATION

The following table sets forth the consolidated capitalization of TransDigm and Holdings as of January 1, 1999, on a historical basis and of Holdings as of January 1, 1999 on a pro forma basis after giving effect to the acquisition of ZMP and the related borrowings under the New Credit Facility as if they had occurred on January 1, 1999. This table should be read in conjunction with the information contained in "Unaudited Pro Forma Financial Information" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" as well as the Consolidated Historical Financial Statements and the notes thereto included elsewhere in this prospectus.

UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

The following pro forma consolidated financial information of TransDigm and Holdings has been derived by the application of pro forma adjustments to Holdings' historical consolidated financial statements for the year ended September 30, 1998 and the thirteen weeks ended January 1, 1999 and as at January 1, 1999. The pro forma consolidated statements of operations give effect to each of the Transactions as if they had been consummated at the beginning of each respective period. The pro forma consolidated balance sheet gives effect to the acquisition of ZMP and the related borrowings under the New Credit Facility as if they had occurred as of the balance sheet date. The adjustments necessary to fairly present this pro forma consolidated financial information have been made based on available information and in the opinion of management are reasonable and are described in the accompanying notes. The pro forma consolidated financial information should not be considered indicative of actual results that would have been achieved had the Transactions been consummated on the respective dates indicated and do not purport to indicate results of operations for any future period. You should read the pro forma consolidated financial statements together with the "The Transactions" and the "Management's Discussion and Analysis of Financial Condition and Results of Operations" sections and the Consolidated Historical Financial Statements and the notes thereto, and other financial information included elsewhere in this prospectus.

As a result of the consummation of the Recapitalization, Odyssey and its co-investors acquired 73.7% of Holdings common stock on a fully diluted basis and certain continuing equity holders of Holdings retained approximately 26.3% of the common stock. Accordingly, the Recapitalization was accounted for as a recapitalization and had no impact on the historical basis of TransDigm's and Holdings' assets and liabilities. The pro forma adjustments were applied to the respective historical consolidated financial statements to reflect and account for the Recapitalization as a recapitalization.

The acquisition of ZMP has been accounted for as a purchase. The purchase price consideration of $41 million in cash and $1 million of costs associated with the acquisition was funded entirely through additional borrowings under the New Credit Facility. The purchase price has been allocated to the assets acquired and liabilities assumed of ZMP and its wholly-owned subsidiary, Adams Rite Aerospace, based on a preliminary analysis of their fair values.

One-time merger charges of approximately $39.6 million and $0.2 million ($28.8 million and $0.1 million after tax), incurred in connection with, or due to, the Recapitalization and the acquisition of ZMP, respectively, were recorded, in each case, in the first quarter of fiscal 1999, as follows:

                                                                                 IN THOUSANDS

SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA

The following table sets forth selected historical consolidated financial information of Holdings. The selected historical consolidated financial data for the fiscal years ended September 30, 1998, 1997, and 1996 have been derived from Holdings' consolidated financial statements, which have been audited by Deloitte & Touche LLP, independent auditors. The selected historical consolidated audited financial data for the fiscal years ended September 30, 1995 and 1994, which have also been derived from Holdings' consolidated financial statements, have been adjusted to give retroactive effect to the change in accounting for put warrants as described in Note 17 to the Consolidated Historical Financial Statements of Holdings included elsewhere in this Prospectus. The selected historical consolidated financial data as of and for the thirteen weeks ended January 1, 1999 and December 26, 1997 has been derived from Holdings' unaudited consolidated financial statements for those periods, which, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results of operations, financial position, and cash flows. The results for the thirteen weeks ended January 1, 1999 are not necessarily indicative of results that may be expected for the entire year. Separate financial information for TransDigm is not presented since the New Notes will be guaranteed by Holdings and all direct and indirect domestic subsidiaries of TransDigm, and since Holdings has no operations or assets separate from its investment in TransDigm.

The Marathon Acquisition was completed on August 8, 1997. The acquisition was accounted for as a purchase. The results of operations of Marathon are included in Holdings' consolidated financial statements from the date of such acquisition.

You should read the following table together with the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section and the Consolidated Historical Financial Statements and the notes thereto included elsewhere in this prospectus.

(1) Operating income (loss) includes the effect of a non-cash charge of $4,473 in fiscal 1994 due to a purchase accounting adjustment to inventory associated with the acquisition of the Aerospace Components Group of IMO and a non-cash charge of $666 in fiscal 1997 and $242 in fiscal 1998 due to a purchase accounting adjustment to inventory associated with the acquisition of Marathon.

(2) All of the interest expense reported for fiscal 1994 through 1998 represents interest expense of TransDigm. Holdings had no interest expense prior to the Recapitalization. After the Recapitalization, Holdings has incurred interest expense relating to the Holdings PIK Notes and Holdings has no other interest expense. TransDigm is not an obligor or a guarantor under the Holdings PIK Notes. Interest expense for the Holdings PIK Notes for the thirteen weeks ended January 1, 1999 was $200.

(3) EBITDA represents earnings before interest, taxes, depreciation, amortization, warrant put value adjustment and extraordinary items. EBITDA is presented because management believes it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in Holdings' industry. However, other companies in Holdings' industry may calculate EBITDA differently than Holdings does. EBITDA is not a measurement of financial performance under generally accepted accounting principles and should not be considered as an alternative to cash flow from operating activities, as a measure of liquidity or an alternative to net income as indicators of Holdings' operating performance or any other measures of performance derived in accordance with generally accepted accounting principles. See Holdings' consolidated Statements of Cash Flows included in Holdings' consolidated financial statements.

(4) EBITDA, As Defined, is calculated as follows:

                                                                                                           THIRTEEN WEEKS ENDED

EBITDA, As Defined, is presented herein to provide additional information with respect to the ability of Holdings to satisfy its debt service, capital expenditure and working capital requirements and because certain types of covenants in TransDigm's and Holdings' borrowing arrangements are tied to similar measures. While EBITDA-based measures are frequently used as measures of operations and the ability to meet debt service requirements, they are not necessarily comparable to other similarly titled captions of other companies due to differences in methods of calculation.

(5) For purposes of computing the ratio of earnings to fixed charges, earnings consist of earnings before income taxes plus fixed charges. Fixed charges consist of interest expense, amortization of debt expense and the portion (approximately 33%) of rental expense that management believes is representative of the interest component of rental expense. Earnings were insufficient to cover fixed charges by $7,630, $127 and $32,390 for fiscal 1994, fiscal 1995 and the thirteen weeks ended January 1, 1999, respectively.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

THE STATEMENTS IN THIS DISCUSSION REGARDING THE INDUSTRY OUTLOOK, TRANSDIGM'S EXPECTATIONS REGARDING THE FUTURE PERFORMANCE OF ITS BUSINESSES, AND THE OTHER NONHISTORICAL STATEMENTS IN THIS DISCUSSION ARE FORWARD-LOOKING STATEMENTS. THESE FORWARD-LOOKING STATEMENTS ARE SUBJECT TO NUMEROUS RISKS AND UNCERTAINTIES, INCLUDING BUT NOT LIMITED TO THE RISKS AND UNCERTAINTIES DESCRIBED IN THE "RISK FACTORS" SECTION. YOU SHOULD READ THE FOLLOWING DISCUSSION OF THE RESULTS OF OPERATIONS AND FINANCIAL CONDITION OF TRANSDIGM TOGETHER WITH THE SECTIONS ENTITLED "RISK FACTORS" AND "SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA" AND WITH THE CONSOLIDATED HISTORICAL FINANCIAL STATEMENTS AND NOTES THERETO INCLUDED ELSEWHERE IN THIS PROSPECTUS. TRANSDIGM'S FISCAL YEAR ENDS ON SEPTEMBER 30 OF THE YEARS INDICATED.

OVERVIEW

TransDigm is a leading supplier of highly engineered aircraft components for use on nearly all commercial and military aircraft. TransDigm sells its products to commercial airlines and aircraft maintenance facilities in the aftermarket, to most original equipment manufacturers ("OEMs") of aircraft and to various agencies of the United States government. Sales of TransDigm's products are made directly to these organizations as well as through U.S. and international distributors who maintain inventories throughout the world of products purchased from TransDigm and others. TransDigm generates most of its EBITDA, As Defined from sales of replacement parts in the aftermarket, including to the airlines. This is because most of TransDigm's OEM sales are on an exclusive sole source basis; therefore, in most cases, TransDigm is the only certified provider of these parts in the aftermarket. Because aftermarket parts sales are driven by the size of the worldwide aircraft fleet, they are relatively stable and generate recurring revenues over the life of an aircraft that are many times the size of the original OEM purchases.

TransDigm provides its products to commercial airlines, such as United Airlines and Continental Airlines, large commercial transport and regional and business aircraft OEMs such as Boeing, Bombardier and Cessna and various agencies of the United States government. While aftermarket and OEM sales have historically each accounted for approximately half of TransDigm's net sales, aftermarket sales typically carry a substantially higher gross margin than sales to OEMs.

Management believes that the aircraft components industry has historically been sensitive to changes in revenue passenger miles and, to a lesser extent, to airline profitability, each of which has historically been correlated with changes in general economic conditions, and the size and age of the worldwide aircraft fleet. On a worldwide basis, revenue passenger miles have increased from approximately 978 billion in 1985 to approximately 1,719 billion in 1996 at a compound annual growth rate of approximately 6%. See "Business--Industry." In addition, management believes less than 20% of TransDigm's net sales during fiscal 1998 and the thirteen weeks ended January 1, 1999 were attributable to sales to manufacturers of large commercial transports such as Boeing and Airbus. As a result, increases and decreases in the manufacture of large commercial transports only affect a portion of TransDigm's net sales.

Management has, since 1993, implemented a number of programs that have had a positive impact on the profitability and strategic positioning of TransDigm. To ensure a competitive cost structure, TransDigm consolidated the Adel Fasteners and Wiggins Connectors divisions into AdelWiggins and the AeroProducts and Controlex divisions into AeroControlex and, in fiscal 1994, consolidated TransDigm's four manufacturing facilities into two locations. Beginning in fiscal 1994, management reorganized the business along 11 major product lines in order to streamline new business initiatives, increase accountability and facilitate greater responsiveness to customer needs. As a result of the acquisition of ZMP, TransDigm acquired four additional major product lines of Adams Rite Aerospace. Management

42

intends to reorganize the business along 15 major product lines to incorporate the four major product lines of Adams Rite Aerospace.

TransDigm's historical financial results are also affected by the acquisition of Marathon on August 8, 1997. Marathon's operations were consolidated with those of TransDigm as of the acquisition date.

The Recapitalization was recorded as a recapitalization for accounting purposes. As a result of the Recapitalization, including the financing and the application of the proceeds thereof, TransDigm incurred certain nonrecurring costs and charges, consisting primarily of compensation costs for management bonuses and stock options which were canceled in conjunction with the Recapitalization, the cost of terminating a financial advisory services agreement with an affiliate of one of TransDigm's stockholders, the write-off of deferred financing costs, and professional, advisory and financing fees. A one-time charge of approximately $39.6 million ($28.8 million after tax) was recorded for the thirteen weeks ended January 1, 1999. Because the cash costs included in this charge were funded principally through the proceeds of the offering of the Old Notes and borrowings under the New Credit Facility, this cost did not materially impact TransDigm's liquidity, ongoing operations or market position. For a discussion of the consequences of the incurrence of indebtedness as a result of the Transactions, see the heading "--Liquidity and Capital Resources" in this section.

On April 23, 1999, TransDigm acquired ZMP, the corporate parent of Adams Rite Aerospace. Adams Rite Aerospace is a well established supplier of highly engineered aircraft components that will complement the businesses of AdelWiggins, AeroControlex and Marathon. Through the acquisition of ZMP, TransDigm acquired four additional major product lines of Adams Rite Aerospace consisting of mechanical hardware, fluid control products, electromechanical control products and oxygen systems related products. For its fiscal 1998, Adams Rite Aerospace generated net sales, operating income and EBITDA, As Defined, of $34.2 million, $3.6 million and $5.4 million, respectively.

(1) Together with the formation of TransDigm on September 30, 1993, TransDigm issued subordinated notes which included detachable warrants to purchase approximately 16,000 shares of non-voting common stock of Holdings at a price of $0.10 per share, exercisable upon certain change of control events, including the Recapitalization. If no transaction constituting a triggering event was consummated prior to July 31, 1999, warrant holders had the right to exercise a put option requiring TransDigm to repurchase all of the warrants at their then appraised fair market value. The warrant put value adjustment for each period indicated reflects the increase in the estimated put value of these warrants that occurred during that period.

CHANGES IN RESULTS OF OPERATIONS

THIRTEEN WEEKS ENDED JANUARY 1, 1999 COMPARED WITH THIRTEEN WEEKS ENDED DECEMBER
26, 1997

- NET SALES. Net sales increased by $2.1 million, or 8.0%, to $28.2 million for the thirteen weeks ended January 1, 1999 from $26.1 million for the thirteen weeks ended December 26, 1997. Substantially all of the increase was due to higher aftermarket sales, principally for large commercial transport aircraft, reflecting TransDigm's continued efforts to increase sales in this area because of the larger gross margins that are generally realized from such sales.

- GROSS PROFIT. Gross profit (net sales less cost of sales) increased by $1.9 million, or 16.7%, to $13.3 million for the thirteen weeks ended January 1, 1999 from $11.4 million for the thirteen weeks ended December 26, 1997. This improvement in gross profits was principally the result of the higher aftermarket sales discussed above and the larger gross margins that are associated with such sales. Gross profit for the thirteen weeks ended December 26, 1997 includes the effect of a non-cash charge of $0.3 million due to a purchase accounting adjustment to inventory associated with the acquisition of Marathon. Gross profit also increased as a percentage of net sales from 43.7% for the thirteen weeks ended December 26, 1997 to 47.0% for the thirteen weeks ended January 1, 1999 due to the non-cash charge from the Marathon inventory purchase accounting adjustment and the increase in aftermarket sales.

- SELLING AND ADMINISTRATIVE. Selling and administrative expense was unchanged at $2.7 million for the thirteen weeks ended January 1, 1999 and December 26, 1997. Selling and administrative expenses as a percentage of net sales decreased from 10.2% for the thirteen weeks ended December 26, 1997 to 9.5% for the thirteen weeks ended January 1, 1999 due to the increase in sales referred to above and continued programs to manage expenses.

- AMORTIZATION OF INTANGIBLES. Amortization of intangibles was unchanged at $0.6 million for the thirteen weeks ended January 1, 1999 and December 26, 1997.

- RESEARCH AND DEVELOPMENT. Research and development expense increased $.1 million, or 33.3%, to $.4 million for the quarter ended January 1, 1999 from $.3 million for the comparable quarter last year. This increase was primarily attributable to continued new product development at each of AdelWiggins, AeroControlex and Marathon. Research and development expense as a percentage of net sales remained relatively constant at 1.6% for the thirteen weeks ended January 1, 1999 and 1.3% for the thirteen weeks ended December 26, 1997.

- MERGER EXPENSES. Merger costs totaling $39.6 million were incurred during the thirteen weeks ended January 1, 1999 in connection with the Merger and Recapitalization. The nature of the merger-related charges is detailed below:

                                                                                (IN THOUSANDS)
Compensation expense on stock options.........................................    $   19,437
Management bonuses............................................................         6,450
Termination of financial advisory service agreement...........................         5,850
Professional fees and expenses................................................         6,673
Write-off of deferred financing costs.........................................           552
Other.........................................................................           631
                                                                                     -------
                                                                                  $   39,593
                                                                                     -------
                                                                                     -------

- OPERATING INCOME (LOSS). Operating income decreased from $7.8 million for the thirteen weeks ended December 26, 1997 to a loss of $30.1 million for the thirteen weeks ended January 1, 1999 due to the merger expenses discussed above. Operating income, excluding merger-related expenses, increased by $1.7 million, or 21.8%. As a percentage of net sales, operating income before merger-related

44

expenses increased to 33.6% for the thirteen weeks ended January 1, 1999 from 29.7% for the thirteen weeks ended December 26, 1997. This increase was primarily attributable to the increase in sales volume and gross profits referred to above.

- INTEREST EXPENSE. Interest expense increased by $1.2 million, or 109%, to $2.3 million for the thirteen weeks ended January 1, 1999 from $1.1 million for the thirteen weeks ended December 26, 1997 as a result of the increase in the average level of outstanding borrowings in connection with the Recapitalization.

- INCOME TAXES. Income tax expense (benefit) as a percentage of income (loss) before income taxes was (23.3)% for the thirteen weeks ended January 1, 1999 compared to 38.6% thirteen weeks ended December 26, 1997. The tax benefit recorded for the thirteen weeks ended January 1, 1999 was significantly impacted by the non-deductible expenses incurred in connection with the Recapitalization.

- NET INCOME (LOSS). TransDigm incurred a net loss of $24.8 million for the thirteen weeks ended January 1, 1999 compared to net income of $4.1 million for the thirteen weeks ended December 26, 1997 primarily as a result of the factors referred to above.

FISCAL YEAR ENDED SEPTEMBER 30, 1998 COMPARED WITH FISCAL YEAR ENDED SEPTEMBER
30, 1997

- NET SALES. Net sales increased by $32.8 million, or 42%, to $110.9 million for fiscal 1998 from $78.1 million for fiscal 1997. Approximately $19.5 million of this increase was attributable to the acquisition of Marathon on August 8, 1997. New business initiatives along with continued strength in airline traffic and airline capital spending resulted in a $7.4 million increase in aftermarket sales, principally for large commercial transport aircraft, and a $5.9 million increase in sales to OEMs.

- GROSS PROFIT. Gross profit (net sales less cost of sales) increased by $22.6 million, or 78.2%, to $51.5 million for fiscal 1998 from $28.8 million for fiscal 1997. Approximately $9.5 million of this increase was attributable to the acquisition of Marathon, including a $0.4 million reduction in the charge to Marathon's cost of sales resulting from the write-up of Marathon's inventory in place at the time of the acquisition. In addition, the higher sales discussed above resulted in $7.8 million of additional gross profit from aftermarket sales, principally for large commercial transport aircraft, and $5.3 million from sales to OEMs. Gross profit increased as a percentage of net sales from 36.9% in the 1997 period to 46.4% in fiscal 1998. Approximately, 3.8% of this increase was attributable to the acquisition of Marathon and the remainder due to the higher sales discussed above.

- SELLING AND ADMINISTRATIVE. Selling and administrative expense increased by $2.9 million, or 38.2%, to $10.5 million for fiscal 1998 from $7.6 million for fiscal 1997. This increase was primarily attributable to the Marathon acquisition partially offset by reduction in bad debt and environmental expenses of $0.3 million each. Selling and administrative expenses as a percentage of net sales remained relatively constant at 9.7% in fiscal 1997 and 9.4% in fiscal 1998.

- AMORTIZATION OF INTANGIBLES. Amortization of intangibles increased by $0.3 million, or 14.3%, to $2.4 million for fiscal 1998 from $2.1 million for fiscal 1997. The increase in the amortization of intangibles resulted from $0.5 million of additional goodwill amortization relating to the acquisition of Marathon offset by a $0.2 million reduction in the amortization of other intangible assets which became fully amortized in fiscal 1997.

- RESEARCH AND DEVELOPMENT. Research and development expense increased by $0.6 million, or 54.5%, to $1.7 million for fiscal 1998 from $1.1 million for fiscal 1997. This increase was primarily attributable to the acquisition of Marathon. Research and development expense as a percentage of net sales remained relatively constant at 1.4% in fiscal 1997 and 1.6% in fiscal 1998.

45

- OPERATING INCOME. Operating income increased by $18.7 million, or 103.3%, to $36.8 million for fiscal 1998 from $18.1 million for fiscal 1997. Approximately $4.6 million of this increase was attributable to the acquisition of Marathon and the remainder to the other increases in gross profit discussed above. As a percentage of revenues, operating income increased to 33.2% in fiscal 1998 from 23.1% in fiscal 1997.

- INTEREST EXPENSE. Interest expense for fiscal 1998 approximated the amount for fiscal 1997 at $3.2 million and $3.5 million, respectively. The $2.1 increase in interest expense resulting from the additional borrowings made in connection with acquisition of Marathon was more than offset by a $2.4 decrease in interest expense caused by the refinancing of TransDigm's subordinated notes and a general decline in interest rates.

- INCOME TAXES. Income tax expense as a percentage of income before income taxes and the non-deductible warrant put value adjustment increased to 38.6% in fiscal 1998 from 35.5% in fiscal 1997. The increase in the effective rate resulted from higher non-deductible expenses, including the amortization of goodwill recognized in connection with the Marathon acquisition.

- NET INCOME. Net income increased by $10.9 million, or 340.6%, to $14.1 million for fiscal 1998 from $3.2 million for fiscal 1997 primarily as a result of the factors referred to above and an extraordinary loss in 1997 of $1.5 million partially offset by a $1.7 million increase in the warrant put value adjustment during fiscal 1998.

FISCAL YEAR ENDED SEPTEMBER 30, 1997 COMPARED WITH FISCAL YEAR ENDED SEPTEMBER
30, 1996

- NET SALES. Net sales increased by $15.3 million, or 24.3%, to $78.2 million for fiscal 1997 from $62.9 million for fiscal 1996. Approximately $3.0 million of this increase was attributable to the acquisition of Marathon. New business initiatives along with an industry-wide increase in demand resulted in a $7.2 million increase in aftermarket sales, principally for large commercial transport aircraft, and a $5.1 million increase in sales to OEMs.

- GROSS PROFIT. Gross profit (net sales less cost of sales) increased by $7.9 million, or 37.6%, to $28.9 million for fiscal 1997 from $21.0 million for fiscal 1996. Approximately $0.5 million of this increase was attributable to the acquisition of Marathon. The higher sales discussed above resulted in $5.2 million of additional gross profit from aftermarket sales, principally for large commercial transport aircraft, and $2.2 million from sales to OEMs. Gross profit also increased as a percentage of net sales from 33.4% in the 1996 period to 36.9% in fiscal 1997. This increase was primarily attributable to the higher sales discussed above offset by an approximate 1% decline in gross margins due to higher cost of sales resulting from the write-up of Marathon's inventory in place at the time of the acquisition.

- SELLING AND ADMINISTRATIVE. Selling and administrative expense increased by $1.1 million, or 16.9%, to $7.6 million for fiscal 1997 from $6.5 million for fiscal 1996. Approximately $0.4 million of this increase was due to the acquisition of Marathon, $0.3 million resulted from the relocation of TransDigm's corporate headquarters and the remainder was caused by the increase in sales volume which generated larger commission expenses. Selling and administrative expenses declined as a percentage of net sales from 10.3% in fiscal 1996 to 9.7% in fiscal 1997 due to the increase in net sales referred to above coupled with an effort to control expenses.

- AMORTIZATION OF INTANGIBLES. Amortization of intangibles decreased by $1.7 million, or 44.7%, to $2.1 million for fiscal 1997 from $3.8 million for fiscal 1996. Amortization of intangibles decreased by $2.0 million as a result of the termination of an agreement not to compete at the end of fiscal 1996, partially offset by higher amortization of goodwill relating to the acquisition of Marathon.

- RESEARCH AND DEVELOPMENT. Research and development expense increased by $0.3 million, or 37.5%, to $1.1 million for fiscal 1997 from $0.8 million for fiscal 1996. This increase was primarily

46

attributable to continued new product development. Research and development expense as a percentage of net sales remained relatively constant at 1.3% in fiscal 1996 and 1.4% in fiscal 1997.

- OPERATING INCOME. Operating income increased by $8.2 million, or 82.8%, to $18.1 million for fiscal 1997 from $9.9 million for fiscal 1996. As a percentage of revenues, operating income increased to 23.1% in fiscal 1997 from 15.7% in fiscal 1996. This increase was primarily attributable to the increase in sales volume and gross profits referred to above.

- INTEREST EXPENSE. Interest expense decreased by $1.0 million, or 22.2%, to $3.5 million for fiscal 1997 from $4.5 million for fiscal 1996 as a result of a decrease in the average level of outstanding borrowings during fiscal 1997.

- INCOME TAXES. Income tax expense as a percentage of income before income taxes and the non-deductible warrant put value adjustment decreased to 35.5% in fiscal 1997 from 38.0% in fiscal 1996. Foreign sales corporation earnings in fiscal 1997 decreased the effective rate by 2.7%; however, higher non-deductible expenses, including the amortization of goodwill recognized in connection with the Marathon acquisition, increased the effective rate by 0.2%.

- NET INCOME. Net income increased by $2.0 million, or 166.7%, to $3.2 million for fiscal 1997 from $1.2 million for fiscal 1996 primarily as a result of the factors referred to above partially offset by a $2.6 million increase in the warrant put value adjustment during fiscal 1997.

- EXTRAORDINARY LOSS. The extraordinary loss in fiscal 1997 of $1.5 million represents prepayment costs and the write-off of unamortized debt issuance costs, net of income tax benefits, related to the redemption of the subordinated notes which were refinanced with a new $70.0 million credit facility in September 1997.

LIQUIDITY AND CAPITAL RESOURCES

TransDigm generated $23.5 million of cash from operating activities in fiscal 1998 compared to $17.5 million in fiscal 1997 and $18.7 million in 1996. Such increase in operating cash flows is due to improved operating results partially offset by higher working capital. TransDigm used approximately $32.7 million of cash in operating activities during the thirteen weeks ended January 1, 1999 compared to approximately $6.5 million generated during the thirteen weeks ended December 26, 1997. Such decrease in operating cash flows is due to the one-time merger expenses of $39.6 million partially offset by improved operating results.

Cash used in investing activities was approximately $4.3 million in fiscal 1998 compared with $43.2 million in fiscal 1997 and $2.5 million in fiscal 1996. Cash used in investing activities in fiscal 1997 includes $40.9 million related to the acquisition of Marathon, net of cash acquired of $0.7 million. TransDigm's expenditures for property, plant and equipment were $2.5 million in fiscal 1996, $2.3 million in fiscal 1997 and $5.1 million in fiscal 1998. Cash used in investing activities was approximately $0.7 million during the thirteen weeks ended January 1, 1999 compared to approximately $0.1 million generated during the thirteen weeks ended December 26, 1997. The change in investing cash flows is primarily due to post-closing purchase price adjustment of approximately $0.7 million received during the thirteen weeks ended December 26, 1997 as a result of the Marathon acquisition.

Cash used in financing activities for fiscal 1998 was $5.1 million compared to cash provided by financing activities of $28.2 million for fiscal 1997 and cash used in financing activities of $13.5 million for fiscal 1996. During fiscal 1997, the Company obtained a $70.0 million credit facility, the outstanding balance under which has been repaid in connection with the Transactions. Borrowings under this facility of $50.0 million in fiscal 1997 were used to help finance the Marathon acquisition and redeem the Company's outstanding subordinated notes. Cash provided by financing activities during the thirteen weeks ended January 1, 1999 was approximately $16.1 million compared to approximately $20 thousand used during the thirteen weeks ended December 26, 1997. This change in financing cash flows was due

47

to incurrence and refinancing of substantial indebtedness as a result of the Recapitalization and Merger.

As a result of the Recapitalization and the acquisition of ZMP, the Company incurred substantial indebtedness and refinanced certain other indebtedness including all borrowings under the prior credit facility. See the "Capitalization" section. As of January 1, 1999 on a pro forma basis after giving effect to the acquisition of ZMP and the related borrowings under New Credit Facility as if they had occurred on January 1, 1999, Holdings would have had indebtedness consisting of $20.2 million in Holdings PIK Notes and TransDigm would have had indebtedness consisting of (1) $125.0 million in principal amount of the Old Notes and (2) $133.0 million of borrowings under the New Credit Facility, which would have consisted of $9.0 million under a $30.0 million Revolving Credit Facility, a $62.0 million term loan under the Tranche A Facility and a $62.0 million term loan under the Tranche B Facility.

The interest rate for the New Credit Facility is, at TransDigm's option, either (A) a floating rate equal to the Base Rate (as defined in this Prospectus under the heading "Description of Other Indebtedness--The Company's New Credit Facility") plus the Applicable Margin (as defined in this paragraph), or (B) the Eurodollar Rate (as defined in this Prospectus under the heading "Description of Other Indebtedness--The Company's New Credit Facility") for fixed periods of one, two, three, or six months, plus the Applicable Margin. The "Applicable Margin" means the percentage per year equal to (1) in the case of Tranche A Facility and Revolving Credit Facility, (A) bearing an interest rate determined by the Base Rate, 2.50% through February 16, 1999 and 2.25%, 2.00%, 1.75% or 1.50% thereafter depending on Holdings' ability to achieve the respective debt coverage ratio specified in the New Credit Facility, as amended, and (B) bearing an interest rate determined by the Eurodollar Rate, 3.50% through February 16, 1999 and 3.25%, 3.00%, 2.75% or 2.50% thereafter depending on Holdings' ability to achieve the respective debt coverage ratio specified in the New Credit Facility, as amended, and (2) in the case of Tranche B Facility (A) bearing an interest rate determined by the Base Rate, 2.50% and (B) bearing an interest rate determined by the Eurodollar Rate, 3.50%. The New Credit Facility is subject to mandatory prepayment with a defined percentage of net proceeds from certain asset sales, insurance proceeds or other awards that are payable in connection with the loss, destruction or condemnation of any assets, certain new debt and equity offerings and 50% of excess cash flow (as defined in the New Credit Facility) in excess of a predetermined amount under the New Credit Facility.

The Old Notes bear, and the New Notes will bear, interest at 10 3/8%. The New Notes and the Old Notes will not require principal payments prior to maturity. The Revolving Credit Facility and the Tranche A Facility will each mature on the six year anniversary of the initial borrowing date and the Tranche B Facility will mature on the seven and a half year anniversary of the initial borrowing date. The New Credit Facility requires TransDigm to amortize the outstanding indebtedness under each of the Tranche A Facility and the Tranche B Facility, commencing in year 1999, and contains restrictive covenants that will, among other things, limit the incurrence of additional indebtedness, the payment of dividends, transactions with affiliates, asset sales, acquisitions, mergers and consolidations, liens and encumbrances, and prepayments of other indebtedness. See the "Description of the New Notes" and "Description of Other Indebtedness--The Company--The New Credit Facility" section.

TransDigm's primary cash needs will consist of capital expenditures and debt service. TransDigm incurs capital expenditures for the purpose of maintaining and replacing existing equipment and facilities and, from time to time, for facility expansion. Capital expenditures totaled approximately $2.5 million, $2.3 million, $5.1 million, $0.6 million and $0.7 million in fiscal 1996, fiscal 1997, fiscal 1998, the thirteen weeks ended December 26, 1997 and the thirteen weeks ended January 1, 1999, respectively. TransDigm estimates that capital expenditures, excluding those of Adams Rite Aerospace, will total approximately $5.6 million in fiscal 1999.

48

TransDigm intends to pursue additional acquisitions that present opportunities to realize significant synergies, operating expense economies or overhead cost savings or to increase TransDigm's market position. TransDigm regularly engages in discussions with respect to potential acquisitions and investments. However, there are no binding agreements with respect to any material acquisitions at this time, and we cannot assure you that we will be able to reach an agreement with respect to any future acquisition. TransDigm's acquisition strategy may require substantial capital, and no assurance can be given that TransDigm will be able to raise any necessary funds on terms acceptable to TransDigm or at all. If TransDigm incurs additional debt to finance acquisitions, its total interest expense will increase. See "Risk Factors--Risks Related to Potential Future Acquisitions."

TransDigm's ability to make scheduled payments of principal of, or to pay the interest on, or to refinance, its indebtedness, including the New Notes and the Old Notes, or to fund planned capital expenditures and research and development will depend on their future performance, which, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond their control. Based upon the current level of operations and anticipated cost savings and revenue growth, management believes that cash flow from operations and available cash, together with available borrowings under the New Credit Facility, will be adequate to meet TransDigm's future liquidity needs for at least the next few years. TransDigm may, however, need to refinance all or a portion of the principal of the New Notes and the Old Notes on or prior to maturity. There can be no assurance that TransDigm's business will generate sufficient cash flow from operations, that anticipated revenue growth and operating improvements will be realized or that future borrowings will be available under the New Credit Facility in an amount sufficient to enable TransDigm to service its indebtedness, including the New Notes and the Old Notes, or to fund its other liquidity needs. In addition, there can be no assurance that TransDigm will be able to effect any such refinancing on commercially reasonable terms or at all. See the "Risk Factors" section.

BACKLOG

Management believes that sales order backlog (i.e. orders for products that have not yet been shipped) is a useful indicator of sales to OEMs. As of January 1, 1999, TransDigm estimated its sales order backlog at $45.9 million compared to an estimated $43.7 million as of December 26, 1997. The majority of the purchase orders outstanding as of January 1, 1999 are scheduled for delivery within the next twelve months. Purchase orders are generally subject to cancellation by the customer prior to shipment. The level of unfilled purchase orders at any given date during the year will be materially affected by the timing of TransDigm's receipt of purchase orders and the speed with which those orders are filled. Accordingly TransDigm's backlog as of January 1, 1999 is not necessarily indicative of actual shipments or sales for any future period, and period-to-period comparisons may not be meaningful.

FOREIGN OPERATIONS

TransDigm manufactures virtually all of its products in the United States. However, a significant portion of TransDigm's current sales are conducted abroad. Approximately 16%, 20%, and 20% of TransDigm's net sales in fiscal 1998, fiscal 1997, and fiscal 1996, respectively, were made directly to foreign end-users. These sales are subject to numerous additional risks, including the impact of foreign government regulations, currency fluctuations, political uncertainties and differences in business practices. There can be no assurance that foreign governments will not adopt regulations or take other action that would have a direct or indirect adverse impact on the business or market opportunities of TransDigm within such governments' countries. Furthermore, there can be no assurance that the political, cultural and economic climate outside the United States will be favorable to TransDigm's operations and growth strategy.

49

INFLATION

Many of TransDigm's raw materials and operating expenses are sensitive to the effects of inflation, which could result in higher operating costs. The effects of inflation on TransDigm's businesses during fiscal 1998, 1997 and 1996 were not significant.

NEW ACCOUNTING STANDARDS

In June 1997, the Financial Accounting Standards Board issued SFAS No. 130, "Reporting Comprehensive Income." The statement requires that an enterprise classify items of other comprehensive income by their nature in a financial statement and display the accumulated balance of other comprehensive income separately from retained earnings and additional paid-in capital in the equity section of a statement of financial position. TransDigm adopted this standard during the first quarter of fiscal 1999.

In June 1997, the Financial Accounting Standards Board issued SFAS No. 131, "Disclosures About Segments of an Enterprise and Related Information." The statement requires that a public business enterprise report financial and descriptive information about its reportable operating segments such as a measure of segment profit or loss, certain specific revenue and expense items, and segment assets. TransDigm will adopt this standard for its fiscal 1999 year-end financial statements.

In February 1998, the Financial Accounting Standards Board issued SFAS No. 132, "Employer's Disclosures about Pensions and Other Postretirement Benefits." The statement requires an enterprise to disclose certain information in its year-end financial statements about its pension and postretirement benefits, including a reconciliation of beginning and ending balances of the benefit obligation, the funded status of the plans, and the amount of net periodic benefit cost recognized. TransDigm will adopt this standard in fiscal 1999.

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." This statement establishes accounting and reporting standards for derivative instruments embedded in other contracts, (collectively referred to as derivatives) and for hedging activities. It requires that an entity recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value. If certain conditions are met, a derivative may be specifically designated as (a) a hedge of the exposure to changes in the fair value of a recognized asset or liability or an unrecognized firm commitment, (b) a hedge of the exposure to variable cash flows of a forecasted transaction, or
(c) a hedge of the foreign currency exposure of a net investment in a foreign operation, an unrecognized firm commitment, an available-for-sale security, or a foreign-currency-denominated forecasted transaction. TransDigm will adopt this standard during fiscal 2000.

While management has not completed its analysis of these new accounting standards contained in SFAS No. 131, SFAS No. 132 and SFAS No. 133, the adoption of these standards is not expected to have a material effect on TransDigm's financial statements.

IMPACT OF YEAR 2000 ISSUE

TransDigm has completed a review of its information technology systems in the Waco, Texas site and is completing a review of its information technology systems in the Los Angeles, California site and the Cleveland, Ohio site. TransDigm is also completing a review of its embedded systems at each of the three sites, in order to assess its exposure to Year 2000 issues. These reviews, including testing and verification, will be completed internally. Management anticipates that these reviews, including testing and verification will be completed by June 1999. Prior to the acquisition of ZMP, ZMP represented to TransDigm that the review of Adams Rite Aerospace's information technology systems and embedded systems have been completed and that it believes the plan to make those systems Year 2000 compliant can be fully implemented by December 1999. However, TransDigm has not initiated its independent review of Adams Rite Aerospace's information technology systems or embedded systems. Although management believes that any repairs necessary to make their embedded systems Year 2000 compliant

50

can be completed internally, until TransDigm has completed its review, testing and verification of its embedded systems, TransDigm will not be in a position to assess the extent of repairs that will be required or the parts that will need to be replaced in order to make its embedded systems Year 2000 compliant. TransDigm purchased all of its computer software from third party vendors and is relying on those vendors to make their software Year 2000 compliant. Except for the vendor of its e-mail system, those vendors have provided TransDigm with third party certifications that their systems are Year 2000 compliant.

TransDigm has distributed questionnaires to assess the Year 2000 compliance of its suppliers and customers; including various agencies of the United States government. However, TransDigm has not currently gathered sufficient data to determine to what extent those suppliers and customers are Year 2000 compliant. Prior to the acquisition of ZMP, ZMP represented to TransDigm that it has received confirmation from the material suppliers and customers of Adams Rite Aerospace of their respective Year 2000 compliance.

In the event that Year 2000 problems arise within TransDigm or that its significant suppliers or customers, including various agencies of the United States government, do not successfully and timely achieve Year 2000 compliance, the result may be a delay in its receiving orders and collecting payments, leading to a temporary loss of revenue. TransDigm has incurred $180,000 in costs associated with Year 2000 compliance and, excluding Adams Rite Aerospace, anticipates incurring $150,000 of additional costs in the future. Because TransDigm has not independently reviewed the information technology systems and the embedded systems of Adams Rite Aerospace, management does not currently have adequate data to estimate the additional cost that may have to be incurred by TransDigm in order to make Adams Rite Aerospace's systems Year 2000 compliant. However, since the anticipated additional cost reflects the cost of the review, testing, verification and repair to be completed internally, TransDigm has not allocated such cost between its embedded systems and its information technology systems. TransDigm may, however, have to bear further Year 2000 costs and expenses which could have a material adverse effect on its business.

TransDigm has no formal contingency plan in the event Year 2000 problems arise with respect to its information technology systems; however, TransDigm's accounting and business information systems are not complex and manual procedures could be performed for a period of time to provide the information necessary to continue to operate the business. In the event that Year 2000 problems arise within our embedded systems, TransDigm intends to employ their existing subcontractor machinists to manufacture the affected components.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

All of TransDigm's outstanding indebtedness at September 30, 1998 was repaid in connection with the Merger and Recapitalization. At January 1, 1999, TransDigm is subject to interest rate risk with respect to borrowings under its New Credit Facility as the interest rates on such borrowings vary with market conditions and, thus, the amount of outstanding borrowings approximates the fair value of the indebtedness. On a historical basis, the weighted average interest rate on the $91.0 million of borrowings outstanding under the New Credit Facility at January 1, 1999 was 8.75%. Also outstanding at January 1, 1999 was $125.0 million of TransDigm indebtedness in the form of the Old Notes and $20.0 million of Holdings PIK Notes. The interest rates on both of these borrowings are fixed at 10 3/8% and 12% per year, respectively. Although management believes that the fair value of these debt obligations approximates their outstanding balance at January 1, 1999, the effect of a hypothetical one percentage point decrease in interest rates would increase the estimated fair value of the borrowings by $13.2 million and $2.4 million, respectively.

The acquisition of ZMP, including all of its outstanding common stock, on April 23, 1999 and the related expenses were funded entirely through $42 million of additional borrowings under the New Credit Facility. The weighted average interest rate on all borrowings outstanding under the New Credit Facility on April 23, 1999 was 8.50%. The effect of a hypothetical one percentage point decrease in interest rates would increase the estimated fair value of the borrowings outstanding under the New Credit Facility on April 23, 1999 by approximately $6 million.

BUSINESS

THE COMPANY

TransDigm is a leading supplier of highly engineered aircraft components for use on nearly all commercial and military aircraft. TransDigm sells its products to commercial airlines, aircraft maintenance facilities, aircraft OEMs and to various agencies of the United States government. TransDigm generates most of its EBITDA, As Defined, from sales of replacement parts in the aftermarket including sales to airlines. This is because most of TransDigm's OEM sales are on an exclusive sole source basis; therefore, in most cases, TransDigm is the only certified provider of these parts in the aftermarket. Because aftermarket parts sales are driven by the size of the worldwide aircraft fleet, they are relatively stable and generate recurring revenues over the life of an aircraft that are many times the size of the original OEM purchases. In addition, because TransDigm has over 40 years of experience in most of its product lines, it benefits from a large and growing installed base of aircraft. For fiscal 1998 on a pro forma basis as if the Transactions had occurred on October 1, 1997, TransDigm would have generated net sales, operating income and EBITDA, As Defined, of $145.0 million, $39.3 million and $49.0 million, respectively. For the thirteen weeks ended January 1, 1999 on a pro forma basis as if the Transactions had occurred on October 1, 1998, TransDigm would have generated net sales, operating income and EBITDA, As Defined, of $37.9 million, $10.3 million and $12.8 million, respectively.

TransDigm differentiates itself based on its engineering and manufacturing capabilities, and typically will not bid on non-proprietary "build to print" business. TransDigm has developed strong product brand names within the airline industry and a reputation for high quality, reliability and customer service. TransDigm focuses on developing highly customized products to solve specific problems of aircraft operators and manufacturers. Management estimates that over 80% of the TransDigm's products are of proprietary design. TransDigm provides its products to commercial airlines, such as United Airlines and Continental Airlines, large commercial transport and regional and business aircraft OEMs such as Boeing, Bombardier and Cessna and various agencies of the United States government. While aftermarket and OEM sales each typically account for approximately half of Transdigm's revenues, aftermarket sales typically carry a substantially higher gross margin than sales to OEMs.

TransDigm is comprised of four business units: (1) AdelWiggins, (2) AeroControlex, (3) Marathon, and (4) Adams Rite Aerospace, each of which has a long history in the aircraft components industry. AdelWiggins manufactures an extensive line of fuel and hydraulic system connectors and specialized clamps, heaters and refueling systems. AeroControlex manufactures customized fuel pumps, compressors, valves, couplings and mechanical and electromechanical controls. Adams Rite Aerospace manufactures mechanical hardware, fluid controls, lavatory hardware, electromechanical controls and oxygen systems related products. Marathon manufactures nickel cadmium batteries and static inverters. Marathon and ZMP, the corporate parent of Adams Rite Aerospace, were acquired in August 1997 and April 1999, respectively as a strategic complement to the AdelWiggins and AeroControlex businesses.

TransDigm was formed in 1993 through a management-led buyout of IMO. Since its formation, TransDigm has successfully established leadership positions in well-defined, profitable niches of the aircraft components market that it believes offer sustainable growth opportunities.

INDUSTRY OVERVIEW

The aircraft components industry is highly fragmented, consisting of a large number of small, specialized companies and a limited number of well-capitalized companies. TransDigm competes in niche individual aircraft component markets that it estimates range in size from $10 million to $100 million in annual revenues. TransDigm believes that the small size of its markets, combined with the industry's stringent regulatory approvals and the need to make significant investments in research

52

and development reduces the risk of new entrants. Management believes TransDigm's markets are too small to attract large aerospace companies. In addition, management believes the financial resources and technical expertise required to compete in these markets are beyond the reach of most small companies. Finally all potential competitors must meet the certification requirements and qualification approvals required by the FAA and aircraft OEMs.

AFTERMARKET

Aircraft components need to be serviced regularly to meet FAA standards and aircraft reliability requirements. Demand for aftermarket parts depends on revenue passenger miles and, to a lesser extent, on airline profitability, each of which has historically been correlated with changes in general economic conditions, and the size and age of the worldwide aircraft fleet. Since certain modern aircraft can have useful lives of 30 years or more, spare parts and repair and overhaul services can often generate more sales than the OEM program at significantly higher margins. Management further believes that aftermarket sales help to offset declines in OEM demand as historically airlines and air cargo operators have increased repair and overhaul spending to prolong the life of older aircraft when they delay purchasing new aircraft. Customers in the aftermarket segment include airlines, air cargo operators, aircraft leasing companies, corporate and individual owners of aircraft as well as maintenance, repair and overhaul facilities and various agencies of the United States government, including the military. Management believes that aftermarket sales will continue to be an attractive market as a result of the following factors:

- Air travel traffic continues to increase. In the United States, large commercial transport revenue passenger miles have increased from approximately 431 billion in 1987 to approximately 604 billion in 1997, with 1991 representing the only year in the last ten years in which annual revenue passenger miles decreased. On a worldwide basis, revenue passenger miles have increased from approximately 978 billion in 1985 to 1,719 billion in 1996.

- Total aircraft fleet size has continued to increase despite the volatility of orders and deliveries. At the end of 1997 the large commercial aircraft fleet consisted of approximately 11,900 aircraft, a 4.5% compound annual increase from approximately 7,700 aircraft in 1987. Similarly, the regional aircraft fleet, which consists of turbo-prop and jet aircraft, has increased from approximately 4,900 units in 1987 to approximately 7,500 units in 1997 and the business aircraft fleet has increased from approximately 6,100 units in 1987 to approximately 8,700 units in 1997.

- Aircraft capacity utilization remains at high levels. Passenger load factors, measured as the percentage of occupied seats per flight, for U.S. carriers have increased from 62% in 1987 to 68% in 1996, a record for the industry. During 1997, carriers achieved 69% load factors on a worldwide basis.

OEM

Demand for OEM components depends on new aircraft deliveries. Demand for new aircraft is a function of (1) demand for air travel, (2) aircraft operator profitability, (3) fleet age, (4) regulatory mandates such as noise reduction, and (5) the lag time between order and delivery, which causes airlines to order aircraft according to perceived future need.

- In the early 1990's, many airlines significantly reduced spending on new aircraft and extended the average age of their fleets due to weakened financial performance. With the return of airline profitability, commercial OEMs have experienced a surge in aircraft orders and deliveries which resulted in large commercial transport deliveries growing from a low of 370 aircraft in 1995 to estimated 774 aircraft by the end of 1998.

53

- The regional jet aircraft market has grown significantly in recent years as turbo-jet powered aircraft have made substantial inroads in a market traditionally served by the turboprop powered aircraft and some smaller commercial transports. Regional jets have greater range, faster speed and lower noise levels and are perceived as safer and more comfortable by passengers. U.S. regional revenue passenger miles have increased from approximately 4.0 billion miles in 1987 to approximately 7.7 billion miles in 1996. Regional aircraft deliveries have increased significantly to 115 in 1997 since their introduction in 1988. Industry forecasts by the U.S. Regional Airline Association concluded that approximately 1,280 regional and commuter aircraft will be delivered between 1998 and 2008.

- The business jet market is driven by, among other factors, the increasing popularity of fractional ownership and the increasing demand for more expedient and convenient travel. Deliveries of executive jets have increased significantly since 1987.

- The FAA has mandated that aircraft flying in U.S. airspace comply with Stage 3 noise standards by December 31, 1999. Other countries, particularly in Western Europe, have instituted similar restrictions. As a result, it is expected that there will be an increased demand for aircraft during the next several years as the aircraft which are not retrofitted with "hush kits" are replaced.

- While military spending for new aircraft has significantly declined with the end of the cold war, military parts and repair spending has been relatively stable for the last several years as existing platforms require parts to remain operational.

COMPETITIVE STRENGTHS

TransDigm believes that its key competitive strengths are:

- LARGE INSTALLED PRODUCT BASE AND RECURRING REVENUE STREAM. Management believes that approximately 70% of TransDigm's sales are derived from parts for which it has achieved sole source designation and approximately 80% of TransDigm's products are of proprietary design. As a result, TransDigm has a large and growing installed base of products on large commercial transport and regional, business and military platforms. This installed base affords TransDigm the opportunity to capture a long-term stream of highly profitable aftermarket revenues. Over the life of an aircraft, sales of replacement parts can generate revenues many times the size of the original OEM purchases. Aftermarket sales generate most of TransDigm's EBITDA, As Defined, because they typically carry gross margins that are significantly higher than those generated from OEM sales.

- PROVEN ABILITY TO DEVELOP NEW PRODUCTS. TransDigm has a successful record of introducing solutions-oriented products. TransDigm works closely with aircraft operators and OEMs to identify their unmet needs, such as a component that fails to meet performance expectations or that requires excessive maintenance. TransDigm then utilizes its engineering and design capabilities to develop a prototype for a component that increases the value of the product to the customer. After rigorous testing requirements have been fulfilled and TransDigm has obtained necessary regulatory approvals, the product is made available for sale in the aftermarket and to OEMs. Management believes that its ability to successfully develop new products has contributed to its significant growth.

- DIVERSIFIED BUSINESS MIX. TransDigm's business is fairly evenly distributed between sales in the aftermarket and sales to OEMs. Each of these segments are further distributed among the large commercial transport and regional, business and military aircraft markets. As a result, TransDigm is not overly dependent on any one segment, with the large commercial transport OEM market accounting for less than 20% of sales in fiscal 1998 and the thirteen weeks ended January 1, 1999.

- LEADING POSITIONS IN NICHE MARKETS. With over 40 years of experience in most of its product lines, TransDigm has well-established and highly regarded products and trade names, such as "Adel," "Wiggins," "Controlex," "Marathon" and "SuperPower," and is a leader in many of its product lines.

54

For example, TransDigm believes that it is the leading supplier of tube connectors for use in the flexible fluid systems found on most aircraft platforms.

- EXPERIENCED AND INCENTIVIZED MANAGEMENT TEAM. TransDigm's management team collectively has over 125 years of industry experience and brings a disciplined approach to the business. Management has a proven track record of consolidating operations, reducing overhead and rationalizing costs. Since TransDigm was created in 1993, management has successfully integrated four distinct operating divisions and formed AdelWiggins and AeroControlex. Most recently management has successfully integrated Marathon into TransDigm. The management team has dramatically improved the operating performance and strategic position of TransDigm. EBITDA, As Defined, margins have improved from 19.0% in fiscal 1994 to 39.3% in fiscal 1998. In addition, management owns approximately 12.5% of the capital stock of Holdings on a fully diluted basis, which amount is subject to an increase to approximately 21.3% if certain performance targets are met.

BUSINESS STRATEGY

Key elements of TransDigm's strategy are:

- PROVIDE VALUE ADDED PRODUCTS TO CUSTOMERS. TransDigm will continue to focus on marketing and manufacturing highly engineered products to customers that place a premium on TransDigm capabilities. TransDigm has been effective in communicating to aircraft operators the value of TransDigm's products in terms of cost savings generated by their greater reliability and performance and reduced maintenance requirements. TransDigm's reputation for quality and sole supplier status for many parts has allowed it to achieve substantial gross margins on its aftermarket products. TransDigm intends to continue to develop and market high value added products that carry higher gross margins by emphasizing their benefits to the customer.

- GENERATE NEW BUSINESS INITIATIVES. TransDigm has been successful in identifying and commercializing new business opportunities to drive revenue growth. TransDigm has been particularly effective in creating aftermarket opportunities by developing superior products to retrofit aircraft already in service. New business has contributed significantly to TransDigm's 14% compound annual net sales growth rate, excluding Marathon's net sales growth, since fiscal 1994, which TransDigm believes is well in excess of the industry average growth rate during the same period. TransDigm intends to continue to aggressively pursue growth opportunities through its new business initiatives.

- REALIZE PRODUCTIVITY SAVINGS. Management will continue to focus on improving operating margins through manufacturing improvements and increases in employee productivity. Management has achieved significant increases in productivity since fiscal 1994. Manufacturing facilities have been rationalized and manufacturing and other business practices have been redesigned to maximize efficiency. For example, TransDigm encourages its employees through performance incentives to learn to operate multiple manufacturing stations in order to minimize overall labor costs. This initiative and others like it have enabled TransDigm to significantly increase sales without material increases in headcount.

- PURSUE STRATEGIC ACQUISITIONS. TransDigm intends to aggressively pursue acquisitions where it believes that it can enhance value, reduce costs and develop new business. The aircraft component industry is highly fragmented, with many of the companies in the industry being owned by small operators. TransDigm believes the industry is experiencing consolidation due to customer requirements, inherent economies of scale and technological advancements that favor more sophisticated competitors. TransDigm completed the Marathon acquisition and the acquisition of ZMP in August 1997 and April 1999, respectively. TransDigm regularly engages in discussions with respect to other acquisition and investment opportunities. See the section "Risk Factors" under the heading "Risk Related to Potential Future Acquisitions."

OPERATING GROUPS

TransDigm was formed in 1993 through a management-led buyout of IMO. TransDigm operates four business units: Adelwiggins, AeroControlex, Marathon and Adams Rite Aerospace. AdelWiggins, which is located in Los Angeles, CA and had 177 full time employees at September 30, 1998, manufactures an extensive line of proprietary fuel and hydraulic system connectors and specialized clamps, heaters and refueling systems. AdelWiggins was formed in 1994 from the consolidation of the Adel Fasteners and Wiggins Connectors divisions acquired from IMO. Founded in 1938 and 1925, respectively, both Adel Fasteners and Wiggins Connectors have had a long history in the aircraft components industry and enjoy strong brand name recognition.

AeroControlex, which is located in Cleveland, OH and had 183 full-time employees at September 30, 1998, manufactures proprietary pumps, compressors, valves, couplings and mechanical controls for commercial and military aircraft and marine applications. AeroControlex was formed in 1994 from the consolidation of the Aeroproducts and Controlex divisions acquired from IMO.

Marathon, which is located in Waco, TX and had 178 full-time employees at September 30, 1998, was acquired by TransDigm in August 1997 as a strategic addition to its AdelWiggins and AeroControlex business lines. Marathon has been a leading manufacturer of nickel-cadmium batteries and static inverters to the aerospace industry since its founding in 1923. Management has successfully integrated the Marathon business unit into the TransDigm culture and believes that, over the next several years, Marathon offers upside potential similar to that achieved with the integration of AdelWiggins and AeroControlex.

Adams Rite Aerospace, which is located in Fullerton, CA and had 253 employees at April 24, 1998, was acquired in April 1999 as a strategic addition to TransDigm's other three business lines. Adams Rite Aerospace is a leading manufacturer of mechanical hardware, fluid controls, lavatory hardware, electromechanical controls and oxygen systems related products and sells its products to substantially the same customer base, primarily on a sole source basis, as that of TransDigm's other three business lines.

PRODUCTS

TransDigm's products are found on virtually all types of aircraft, and TransDigm supplies components to all major domestic and international airlines. Management estimates that over 80% of TransDigm's products are of proprietary design and approximately 70% of TransDigm's sales are derived from parts for which it has achieved sole source designation. TransDigm's products are grouped into fifteen major product lines, each of which is profitable and is operated as a semiautonomous business unit.

Much of TransDigm's recent success has been due to its identification and development of new products for sale in the commercial aftermarket. TransDigm works closely with customers to identify their unmet needs, such as a component that fails to meet performance expectations or that requires excessive maintenance. TransDigm then utilizes its engineering and design capabilities to develop a prototype for a component that increases value of the product to the customer. After rigorous testing requirements have been fulfilled and TransDigm has obtained necessary regulatory approvals, the product is made available for sale in the aftermarket and to OEMs.

ADELWIGGINS. Adelwiggins manufactures over 8,000 SKUs, representing 40% of TransDigm's sales for fiscal 1998, which constitute five of TransDigm's fifteen major product lines: (A) flexible tube connectors, (B) special connectors, (C) Adel clamps, (D) Wiggins service systems and (E) heaters and hoses. Tube connectors are fluid line connectors that provide leak tight joints and are found in flexible fluid systems on most aircraft platforms including fuel, water, waste and environmental systems. Special connectors are connectors designed to allow breaking and reconnecting of fluid lines under pressure

56

and are found in quick disconnect applications including refueling and other fluid management systems for military, space and rocket launch applications and in frangible connectors for large commercial transports. Adel clamps include cushioned clamps, engineered elastomers, bare metal clamps, clampshells, block clamps and quick release clamps used to support fuel, hydraulic, fluid and electric lines and are found in a broad variety of clamps located throughout the airplane, including in engines to address high temperature and high vibration requirements. Wiggins service systems include proprietary refueling nozzles and systems, vents, receivers and quick disconnects and are found in mine refueling equipment and military applications such as tanks and armored vehicles that require high flow capabilities and universal compatibility. Heaters and hoses consists of specialized hoses and heaters, including blanket and ribbon heaters, heater cuffs, heated nipples and gaskets and heated tanks throughout the aircraft and are designed to prevent freezing of fluids such as potable water and waste and to provide heat for hot water service applications.

AdelWiggins designs its products specifically to meet the engineering requirements of its customers, focusing on aspects such as: reduced-profile or low-profile geometry, broad ranges of high-temperature service, ease of installation and, where possible, utilization of advanced materials to maximize the strength-to-weight ratios of its components. These factors are critical to both OEMs and commercial airlines given their emphasis on reducing both acquisition and operating costs. In addition, TransDigm believes AdelWiggins' products have a reputation for long service lives and extremely high reliability in stressful operating environments.

Approximately 60% of AdelWiggins' products are proprietary products designed to meet specific customer needs. The remaining 40% are industry standard designs. Roughly 55% of AdelWiggins' products are sole sourced, which is advantageous to TransDigm because it creates significant switching costs associated with the development and qualification of alternative engineered solutions. This sole sourced status has contributed to AdelWiggins achieving aftermarket sales of 30% of its net sales in fiscal 1998. See "Business--Customers."

AEROCONTROLEX. AeroControlex manufactures over 13,000 SKUs, representing 39% of TransDigm's sales for fiscal 1998, which constitute three of TransDigm's fifteen major product lines: (A) mechanical controls, (B) pumps and (C) valves and quick disconnects. Mechanical controls include electromechanical control systems, sliding and ball bearing control cables and gearboxes which are found in the lavatory drain, throttle control, engine feedback, landing gear release and in ejection seats and fuel and air systems. Pumps primarily include gear pumps which are found in hydraulic and fuel systems applications. Valves and quick disconnects include fuel and air system valves, compressors and quick disconnects which are found in air conditioning packages and fuel, radar and potable water systems.

AeroControlex designs, manufactures and sells pumps, compressors, valves, couplings and mechanical controls primarily for the commercial and military aircraft markets. AeroControlex has developed a reputation for providing high-quality, reliable products consistently delivered on time. AeroControlex works closely with customers to leverage its engineering expertise to create technical solutions to customer-specific problems. About 95% of AeroControlex products are proprietary and over 90% are sold on a sole-source basis, which is advantageous to TransDigm because its creates significant switching costs associated with the development and qualification of alternative engineered solutions. This sole sourced status has contributed to AeroControlex achieving aftermarket sales of 68% of its net sales in fiscal 1998. See "Business--Customers."

MARATHON. Marathon manufactures over 5,000 SKUs, representing 21% of TransDigm's sales for fiscal 1998, which constitute three of TransDigm's fifteen major product lines: (A) vented cell nickel-cadmium batteries, (B) static inverters and (C) sealed cell nickel-cadmium batteries. Vented cell nickel- cadmium batteries and sealed cell batteries are used for engine starting and emergency power aboard various aircraft while static inverters convert direct current to alternating current for use in applications

57

such as flight instrumentation and communication. Marathon products are used for numerous military applications, such as the F-16, F-18, Blackhawk, Apache and Cobra programs. Approximately 50% of Marathon's products have achieved sole sourcing status with its customers.

Marathon is one of the worlds leading manufacturers of vented cell nickel-cadmium batteries, which require frequent maintenance, as individual cells within a battery are replaced throughout the life of the battery. Marathon, which manufactures and sells both entire batteries and individual cells, realizes replacement revenue in the aftermarket throughout the life of the battery as a result of its position as a sole source supplier of products that accounted for over 50% of its sales. Over 95% of Marathon's sales are proprietary, the status of which has contributed to Marathon achieving aftermarket sales of 69% of its net sales in fiscal 1998. Vented cell batteries are marketed under the Marathon-TM- and SuperPower-TM- brand names.

ADAMS RITE AEROSPACE. Adams Rite Aerospace manufactures over 6,000 SKUs, which constitute four of TransDigm's fifteen major product lines: (A) mechanical hardware, (B) fluid control products, (C) electromechanical control products and (D) oxygen systems related products. Mechanical hardware include hardware installed inside the aircraft, such as overhead stowage bin latches, lavatory indicator and door latches, seat control cables and decompression latches, and hardware installed outside of the aircraft, such as door bolting systems. Fluid control products include various aircraft water system components, such as spigots, soap dispensers and water shut-off valves as well as entire self-contained water systems. Electromechanical control products include throttle quadrants, control wheels, electric strikes, speed brake controls and a variety of handle grips. Oxygen systems related products include oxygen cylinders, masks, reducers and control panels.

SALES AND MARKETING

Consistent with TransDigm's overall strategy, TransDigm's sales and marketing organization is structured to understand and anticipate the needs of customers in order to continually develop a stream of technical solutions that generate significant value. Particular focus is on the high-margin, repeatable aftermarket segment.

TransDigm has structured AdelWiggins', AeroControlex's and Marathon's sales efforts along their collective eleven major product lines, assigning a Product Line Manager to each line. Management anticipates that Adams Rite Aerospace's sales efforts will be structured in a similar fashion. The Product Line Managers are expected to grow the sales and profitability of their product line faster than the served market and to achieve the targeted annual level of booking, sales, new business and profitability for each product. Assisting the Product Line Managers are Account Managers and Sales Engineers who are responsible for covering both major OEM and airline accounts. They are expected to be familiar with the personnel, organization and needs of specific customers, for achieving total bookings and new business goals at each account, and, in conjunction with the Product Line Managers, for determining when additional resources are required at customer locations. All of TransDigm's sales personnel are compensated in part on their bookings and sales and ability to identify and convert new business opportunities.

Though the majority are employees, the Account Manager function may be performed by independent representatives depending on the specific customer, product and geographic location. TransDigm also uses a limited number of distributors to provide logistical support as well as primary customer contact with certain smaller accounts. TransDigm's largest distributor is Aviall, which provides logistic services to the commercial airlines.

MANUFACTURING AND ENGINEERING

TransDigm maintains four manufacturing facilities. Each facility serves its respective operating group, and comprises manufacturing, distribution and engineering as well as corporate functions,

58

including management, sales and finance. The AdelWiggins, AeroControlex, Marathon and Adams Rite Aerospace facilities encompass approximately 105,000, 44,000, 150,000 and 100,000 square feet of manufacturing space in Los Angeles, California, Cleveland, Ohio, Waco, Texas and Fullerton, California, respectively. In the last several years, management has taken a number of steps to improve productivity and reduce costs, including consolidating operations, developing improved control systems that allow for accurate product line profit and loss accounting, investing in equipment and tooling, installing modern information systems and implementing a broad-based employee training program. Management believes that TransDigm's manufacturing systems and equipment are critical competitive factors that permit it to meet the rigorous tolerances and cost sensitive price structure of aircraft customers. TransDigm concentrates in manufacturing by product line, alternating its equipment among designs as demand requires. TransDigm is in the process of applying its proven manufacturing strategy to the Marathon facility, where its expects to be able to substantially improve Marathon's performance.

Each of TransDigm's operating groups attempts to differentiate itself from its competitors by producing highly engineered products at a low cost. TransDigm's proprietary products are designed by its engineering staff and intended to serve an unmet need in the aircraft component industry, particularly through its new product initiatives. See "--Products." These proprietary designs must withstand the extraordinary conditions and stresses that will be endured by products during use and meet the rigorous demands of TransDigm's customers tolerance and quality requirements.

TransDigm uses sophisticated equipment and procedures to ensure the quality of its products and to comply with military specifications and FAA and OEM certification requirements. TransDigm performs a variety of testing procedures, including testing under different temperature, humidity and altitude levels, shock and vibration testing and X-ray fluorescent measurement. These procedures, together with other customer approved techniques for document, process and quality control, are used throughout TransDigm's manufacturing facilities.

CUSTOMERS

TransDigm's customers include (A) commercial airlines, including national and regional airlines, particularly for aftermarket MRO components, (B) large commercial transport and regional and business aircraft OEMs, (C) various agencies of the United States' government, including the United States military, and (D) various other industrial customers. TransDigm's three largest customers for fiscal 1998, were Aviall, a distributor of aftermarket parts to airlines throughout the world, Boeing which includes, McDonnell Douglas, and various agencies of the United States' government, which accounted for approximately 20%, 14% and 9%, respectively, of TransDigm's net sales in fiscal 1998. TransDigm's top ten customers accounted for approximately 61% of TransDigm's net sales for fiscal 1998.

TransDigm has strong customer relationships with virtually all important large commercial transport, general aviation and military OEMs. The demand for TransDigm's aftermarket parts and services is related to TransDigm's extensive installed base and to revenue passenger miles and, to a lesser extent, to airline profitability and the size and age of the worldwide aircraft fleet. See "Business--Industry Overview." Some of TransDigm's business is executed under long-term agreements with customers which encompass many products under a common agreement. See "Risk Factors-- Customer Contracts." TransDigm is also a leading supplier of components used on United States' designed military aircraft. TransDigm's products are used on a variety of fighter aircraft, and helicopters. Military aircraft using TransDigm's products include the Lockheed F-15 and F-16, the E2C (Hawkeye) and Blackhawk and Apache helicopters.

59

COMPETITION

TransDigm competes with a number of established companies, including divisions of larger companies, that have significantly greater financial, technological and marketing resources than TransDigm. The niche markets within the aerospace industry served by TransDigm are relatively fragmented with several competitors for each of the products and services provided by each of AdelWiggins, AeroControlex and Marathon. Due to the global nature of the commercial aircraft industry, competition in these categories comes from both U.S. and foreign companies. However, TransDigm knows of no single competitor that provides the same range of products and services as those provided by TransDigm. Competitors in TransDigm's product lines range in size from divisions of large corporations to small privately held entitles, with only one or two components in their entire product line. Some of TransDigm's competitors have significantly greater financial, technological and marketing resources than TransDigm. TransDigm believes that its ability to compete depends on high product performance, short lead-time and timely delivery, competitive price, and superior customer service and support. There can be no assurance that TransDigm will be able to compete successfully with respect to these or other factors. See "Risk Factors--Competition."

GOVERNMENTAL REGULATION

The commercial aircraft component industry is highly regulated by both the FAA in the United States and by the Joint Aviation Authorities in Europe, while the military aircraft component industry is governed by military quality specifications. TransDigm, and the components it manufacturers, are required to be certified by one or more of these entities, and, in some cases, by individual OEMs in order to engineer and service parts and components used in specific aircraft models. If material authorizations or approvals were revoked or suspended, the operations of TransDigm would be adversely affected. In the future, new and more stringent government regulations may be adopted, or industry oversight may be heightened, which may have an adverse impact on TransDigm.

TransDigm must also satisfy the requirements of its customers, including OEMs and airlines, that are subject to FAA regulations, and provide these customers with products and services that comply with the government regulations applicable to commercial flight operations. In addition, the FAA requires that various maintenance routines be performed on aircraft components, and TransDigm currently satisfies or exceeds these maintenance standards in its repair and overhaul services. Several of TransDigm's operating divisions include FAA-approved repair stations.

TransDigm's operations are also subject to a variety of worker and community safety laws. OSHA mandates general requirements for safe workplaces for all employees. In addition, OSHA provides special procedures and measures for the handling of certain hazardous and toxic substances. TransDigm believes that its operations are in material compliance with OSHA's health and safety requirement.

RAW MATERIALS AND PATENTS

The components that TransDigm manufactures require the use of various raw materials including titanium, aluminum, nickel powder, nickel screen, stainless steel and cadmium, the availability and prices of which may fluctuate. The price of raw materials and outside processing represented approximately 20% of the sales price of the Company's products for fiscal 1998. Price increases in these supplies may not be able to be recovered. TransDigm also purchases a variety of manufactured component parts from various suppliers although TransDigm is concentrating its orders among fewer suppliers to strengthen its supplier relationships. Raw materials and component parts are generally available from multiple suppliers at competitive prices. However, any delay in TransDigm's ability to obtain necessary raw materials and component parts may affect its ability to meet customer production needs.

60

TransDigm has various trade secrets, proprietary information, trademarks, trade names, patents, copyrights and other intellectual property rights which TransDigm believes, in the aggregate but not individually, are important to its business.

ENVIRONMENTAL MATTERS

TransDigm's operations and current and/or former facilities are subject to federal, state and local environmental laws and to regulation by government agencies, including the Environmental Protection Agency. Among other matters, these regulatory authorities impose requirements that regulate the emission, discharge, generation, management, transportation and disposal of hazardous materials and pollutants, govern response actions to hazardous materials which may be or have been released to the environment, and require TransDigm to obtain and maintain permits in connection with its operations. The extensive regulatory framework imposes significant compliance burdens and risks on TransDigm. Although management believes that TransDigm's operations and its facilities are in compliance in all material respects with applicable environmental laws, there can be no assurance that future changes in such laws, regulations or interpretations thereof or the nature of TransDigm's operations will not require TransDigm to make significant additional expenditures to ensure compliance in the future. According to some environmental laws, a current or previous owner or operator of real property may be liable for the costs of investigations, removal or remediation of hazardous materials at such property. Those laws typically impose liability whether or not the owner or operator knew of, or was responsible for, the presence of such hazardous materials. Persons who arrange, or are deemed to have arranged, for disposal or treatment of hazardous materials also may be liable for the costs of investigation, removal or remediation of those substances at the disposal or treatment site, regardless of whether the affected site is owned or operated by that person. Because TransDigm owns and/or operates a number of facilities, and because TransDigm arranges for the disposal of hazardous materials at many disposal sites, TransDigm may incur costs for investigation, removal and remediation, as well as, capital costs associated with compliance. Although those environmental costs have not been material in the past and are not expected to be material in the future, there can be assurance that changes in environmental laws or unexpected investigations and clean-up costs will not be material. See "Risk Factors--Potential Exposure to Environmental Liabilities." TransDigm does not currently contemplate material capital expenditures for environmental compliance remediation for fiscal 1999 or fiscal 2000.

The soil and groundwater beneath TransDigm's facility in Waco, Texas, have been impacted by releases of hazardous materials. Because the majority of the contaminants identified to date are presently below action levels prescribed by the Texas Natural Resources Conservation Commission, TransDigm does not believe the condition of the soil and groundwater at the Waco facility will require incurrence of material capital expenditures; however, there can be no assurance that additional contamination will not be discovered or that the remediation required by the Texas Natural Resources Conservation Commission will not be material to the financial condition, results of operations or cash flows of TransDigm.

PROPERTIES AND FACILITIES

TransDigm owns and operates a 130,000 square foot facility in Los Angeles, California, a 63,000 square foot facility in Cleveland, Ohio and a 219,000 square foot facility in Waco, Texas which is also TransDigm's headquarters. In addition, TransDigm leases and operates a 100,000 square foot facility in Fullerton, California. TransDigm also leases certain of its other facilities. Management believes that its machinery, plants and offices are in satisfactory operating condition, and, upon completion of its planned 10,000-20,000 square foot expansion of the AeroControlex manufacturing facility, will have sufficient capacity to meet foreseeable future needs without incurring significant additional capital expenditures.

61

EMPLOYEES

As of September 30, 1998, TransDigm had approximately 540 full-time employees and 45 temporary employees. Approximately 11% of TransDigm employees were represented by the United Steelworkers Union, and approximately 19% were represented by the United Automobile, Aerospace and Agricultural Implement Workers of America. Collective bargaining agreements between TransDigm and these labor unions expire on April 2002 and November 2000, respectively. TransDigm considers its relationship with its employees generally to be satisfactory and does not expect any difficulty in reaching new collective bargaining agreements.

LEGAL PROCEEDINGS

During the ordinary course of business, TransDigm is from time to time threatened with, or may become a party to, legal actions and other proceedings. While TransDigm is currently involved in some legal proceedings, management believes the results of these proceedings will not have a material effect of the results of operations of TransDigm, in part due to indemnification arrangements. TransDigm believes that its potential exposure to those legal actions is adequately covered by its aviation product and general liability insurance.

MANAGEMENT STOCKHOLDERS AGREEMENT

Together with the consummation of the Recapitalization, Holdings, Odyssey and the employee stockholders of Holdings, including the Named Executive Officers (the "Management Stockholders")

66

entered into a Management Stockholders' Agreement (the "Management Stockholders' Agreement") which governs the shares of common stock of Holdings (the "Common Stock") and options to purchase Common Stock, in each case, held by such persons and including the Rollover Investment and new options and shares obtained in connection with the Recapitalization, and shares acquired thereafter, including upon exercise of options. See "--Stock Option Plan."

The Management Stockholders' Agreement provides that, except for certain transfers to family members and family trusts, no Management Stockholder may transfer Common Stock until the fifth anniversary of the Recapitalization, and thereafter, any proposed transfer will be subject to Holdings' right of first refusal.

The Management Stockholders' Agreement also provides that upon termination of the employment of a Management Stockholder, that Management Stockholder will have certain put rights and Holdings will have certain call rights regarding any Common Stock or any options to purchase Common Stock, in each case, owned by him at that time.

Upon Mr. Peacock's cessation of active service as Chief Executive Officer on or after the third anniversary of the Recapitalization, if TransDigm has achieved specified financial targets, he may require Holdings to repurchase up to 80% of his Common Stock during the period, if any, for which he is serving as non-executive Chairman of the Board. See "--Employment Agreements." Mr. Peacock may thereafter require repurchase of the remaining 20% of his Common Stock on or after the fifth anniversary of the Recapitalization or his later termination of services to Holdings. Holdings will be permitted to honor its obligation to Mr. Peacock by issuing notes under certain circumstances.

If the provisions of any law, the terms of credit and financing arrangements or Holdings' financial circumstances would prevent Holdings from making a repurchase of shares pursuant to the Management Stockholders' Agreement, Holdings will not make such purchase until all such prohibitions lapse, and will then also pay the Management Stockholder a specified rate of interest on the repurchase price.

The Management Stockholders' Agreement further provides that in the event of certain types of transfers of Common Stock by Odyssey the Management Stockholders may participate in those transfers and/or Odyssey may require the Management Stockholders to transfer their shares in those transactions, in each case, on a pro rata basis.

Pursuant to the Management Stockholders' Agreement, the Management Stockholders are entitled to participate on a pro rata basis with, and on the same terms as, Odyssey in any future offering of Common Stock. Those participation rights will lapse following a public offering of Common Stock if the Common Stock so offered is then listed on a national exchange or if the public offering includes 50% or more of the outstanding Common Stock that will have been issued following the offering.

EMPLOYMENT AGREEMENTS

In connection with the Recapitalization, Holdings will enter into an employment agreement with each of Messrs. Peacock and Howley. Pursuant to the agreement with Mr. Peacock, Mr. Peacock will continue to serve as Chairman of the Board and Chief Executive Officer for a period of at least five years, provided that after three years, Mr. Peacock may elect to continue his service either as Chief Executive Officer or as a non-executive Chairman. It is intended that Mr. Howley will be Mr. Peacock's successor. Pursuant to the agreement with Mr. Howley, Mr. Howley will continue to serve as President and Chief Operating Officer of Holdings for a period of at least five years. Those employment agreements also will provide specified severance benefits in the event of termination of employment under certain circumstances.

Each of those employment agreements will provide that in the event the respective executive's employment terminates by reason of death, disability, termination without "cause" or resignation with

67

"good reason" (all as defined in those employment agreements), Holdings will continue payment of base salary, bonus and other perquisites and benefits, in the case of Mr. Howley, for 15 months thereafter and, in the case of Mr. Peacock, for 18 months thereafter or, if terminated prior to the third anniversary of the Recapitalization, until such third anniversary, whichever is longer.

Pursuant to those employment agreements, Messrs. Peacock and Howley will receive annual base salaries no less than $330,000 and $225,000, respectively, in each case, subject to annual increases as determined by the Compensation Committee, and annual cash bonuses based on achievement of performance criteria established by the Board of Directors.

STOCK OPTION PLAN

Holdings intends to adopt the 1998 Stock Option Plan (the "Option Plan"), pursuant to which stock options may be granted to Independent Directors (as defined in the Option Plan), employees and consultants of Holdings, TransDigm and any subsidiary of Holdings or TransDigm (the "Plan Participants"). In addition, the Option Plan will govern those options retained pursuant to the Rollover Investment (the "Rollover Options"). A total of 12.5% of the fully diluted shares of Common Stock of Holdings as of the Recapitalization was reserved for issuance under the Option Plan exclusive of the Rollover Investment. The Chief Executive Officer will have discretion to select the Plan Participants and to specify the terms of such options, including the number of shares, the exercise price and the vesting and expiration of options, subject to approval by the Compensation Committee.

The Compensation Committee will have discretion under the Option Plan to adjust options to reflect certain specified events such as stock dividends, stock splits, recapitalizations, mergers or reorganizations of, or by Holdings. In addition, the Board of Directors will have the right to amend, suspend or terminate the Option Plan, subject to stockholder approval for certain amendments.

The Rollover Options are fully vested and nonforfeitable. In connection with the Recapitalization, Holdings will grant options to certain employees of TransDigm including the Named Executive Officers for the purchase of shares of Common Stock of Holdings (the "New Options"). Such New Options are intended to qualify as "incentive stock options" to the extent permitted under the Internal Revenue Code, and will have an exercise price equal to the price per share paid by Odyssey in connection with the Recapitalization. Twenty percent of each of Messrs. Peacock's and Howley's New Options will become vested as of the date of grant. Subject to the executive's continued employment with and, in the case of Mr. Peacock, continued service as non-executive Chairman of the Board of the Company, the remaining 80% of his New Options will become exercisable upon the earlier of (1) the Company's achievement of specified financial targets or (2) certain specified dates in the Option Agreement. Furthermore, in the event of a "change of control" (as defined in the Option Agreement), a specified percentage of the New Options may become exercisable based upon the terms of such transaction. The New Options generally will expire 10 years after grant and may expire earlier in the event of the executive's earlier termination of employment.

Under the terms of the Tax Allocation Agreement, TransDigm is obligated to make payments to Holdings equal to the amount of income taxes that TransDigm would have owed in respect of federal and state income taxes on behalf of TransDigm and its subsidiaries if TransDigm and its subsidiaries were, for tax purposes, a separate consolidated group.

DESCRIPTION OF OTHER INDEBTEDNESS

TRANSDIGM

THE NEW CREDIT FACILITY

The New Credit Facility, as amended, consists of (1) a $30.0 million Revolving Credit Facility maturing six years from the date of the execution of the New Credit Facility (the "Execution Date") and (2) a term loan facility in an aggregate principal amount of $124.0 million, consisting of the $62.0 million Tranche A Facility maturing six years from the Execution Date and the $62.0 million Tranche B Facility maturing seven and a half years from the Execution Date.

The New Credit Facility provides that TransDigm shall repay, to the extent then outstanding, (1) with respect to the Tranche A Facility, the specified amount set forth in the New Credit Facility for each quarter beginning on August 15, 1999 and (2) with respect to the Tranche B Facility, (A) $310,000 each of the first two quarters beginning on August 15, 1999, (B) $155,000 each of the remaining quarters during the first six years after the Execution Date and (C) $9,713,333 each of the following six quarters. In addition, subject to some exceptions, the New Credit Facility requires mandatory repayment of the outstanding indebtedness under the New Credit Facility and concurrent reduction to the commitments under the New Credit Facility with the proceeds from (1) assets sales, (2) issuance of debt, (3) issuance of equity interests and capital contributions, (4) insurance and condemnation claims, (5) 50% of annual excess cash flow (as defined in the New Credit Facility) from operations in excess of a predetermined amount and (6) 100% of any purchase price adjustment in favor of TransDigm with respect to the acquisition of ZMP, in each case, by or of Holdings, TransDigm or their subsidiaries. TransDigm will have the option at any time and from time to time to prepay the outstanding indebtedness under the New Credit Facility without penalty or premium.

Indebtedness under the New Credit Facility bears interest at the sum of the
(1) Applicable Margin and (2) at the option of TransDigm either the Base Rate or the Eurodollar Rate (as defined in the New Credit Facility). The "Base Rate" means the higher of (i) the rate that Bankers Trust Company ("BTCo") announces from time to time as its prime lending rate, as in effect from time to time, and
(ii) 1/2 of 1% in excess of the overnight federal funds rate. The "Applicable Margin" means the percentage per year equal to (1) in the case of Tranche A Facility and Revolving Credit Facility, (A) bearing an interest rate determined by the Base Rate, 2.50% through February 16, 1999 and 2.25%, 2.00%, 1.75% or 1.50% thereafter depending on Holdings' ability to achieve the respective debt coverage ratio specified in the New Credit Facility and (B) bearing an interest rate determined by the Eurodollar Rate, 3.50% through February 16, 1999 and 3.25%, 3.00%, 2.75% or 2.50% thereafter depending on Holdings' ability to achieve the respective debt coverage ratio specified in the New Credit Facility and (2) in the case of Tranche B Facility (A) bearing an interest rate determined by the Base Rate, 2.50% and (B) bearing an interest rate determined by the Eurodollar Rate, 3.50%.

The New Credit Facility contains various covenants, customary for similar credit facilities or otherwise appropriate under the circumstances, that (1) restrict Holdings, TransDigm and their subsidiaries from various actions, including, among others, mergers and sales of assets, use of proceeds, granting of liens, incurrence of indebtedness, voluntary prepayment of indebtedness, including the Old Notes and the New Notes, capital expenditures, paying dividends, business activities, investments and acquisitions, transactions with affiliates, certain types of restrictions affecting subsidiaries, voluntary prepayment of other Indebtedness and amendments or modifications to instruments governing such other Indebtedness and (2) require TransDigm to achieve and maintain certain financial covenants.

The New Credit Facility includes events of default provisions that are typical for senior credit facilities or otherwise appropriate under the circumstances. All obligations under the New Credit Facility are guaranteed by Holdings and each of the subsidiaries, direct and indirect, of TransDigm. The indebtedness under the New Credit Facility are secured by a pledge of the stock of TransDigm and all

72

of its domestic subsidiaries and a perfected lien and security interest in assets other than real estate (tangible and intangible) of TransDigm, its direct and indirect subsidiaries and Holdings.

HOLDINGS

HOLDINGS PIK NOTES

Concurrently with the issuance of the Old Notes by TransDigm, Holdings issued $20.0 million in aggregate face value of its pay-in-kind notes due 2009 (the "Holdings PIK Notes") to KIA IV-TD and KEP II as part of the Recapitalization. The Holdings PIK Notes were issued to KIA IV-TD and KEP II together with shares of Common Stock of Holdings. The Holdings PIK Notes are unsecured obligations of Holdings, subordinated to the guarantee of the New Credit Facility by Holdings, but senior to the guarantee of each of the Old Notes and the New Notes by Holdings.

Interest on the Holdings PIK Notes accrues at an annual fixed rate of 12% and is payable semiannually in the form of additional Holdings PIK Notes for five years after their issuance. Thereafter, cash interest is payable semi-annually commencing in the year 2004. The Holdings PIK Notes are redeemable at the option of Holdings, in whole or in part, at a price equal to 100% of the principal amount of the Holdings PIK Notes for five years after their issuance and thereafter at the prices set forth in the indenture under the terms of which the Holdings PIK Notes were issued (the "Holdings Indenture"). If Holdings experiences specific kinds of changes in control, it must offer to repurchase the Holdings PIK Notes at a price equal to 101% of the principal amount of the Holdings PIK Notes.

The Holdings PIK Notes contain some covenants on a consolidated basis, including covenants that limit (i) indebtedness, (ii) restricted payments, (iii) distributions by subsidiaries, (iv) transactions with affiliates, (v) sales of assets and subsidiary stock, (vi) dividend and other payment restrictions, and
(vii) mergers or consolidations. The Holdings PIK Notes contain customary events of default and the holders of the Holdings PIK Notes have customary registration rights commencing on the third anniversary of the closing date. The covenants and default provisions in the Holdings Indenture are substantially similar to those contained in the Indenture governing the Old Notes and the New Notes, but are less restrictive in some respects.

73

DESCRIPTION OF THE NEW NOTES

TransDigm will issue the New Notes under an indenture (the "Indenture") among itself, the Guarantors and State Street Bank and Trust Company, as Trustee (the "Trustee"). The following is a summary of the material provisions of the Indenture. It does not include all of the provisions of the Indenture. We urge you to read the Indenture because it defines your rights. The form and terms of the New Notes will be the same as the form and terms of the Old Notes except that the New Notes will be freely transferable by you except as otherwise provided in this Prospectus. See "The Exchange Offer--Purpose and Effect". The terms of the New Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act as in effect on the date of the Indenture. A copy of the Indenture may be obtained from TransDigm. You can find definitions of certain capitalized terms used in the following summary under "--Certain Definitions." For purposes of this section, references to (1) "TransDigm" means TransDigm Inc. and not its Subsidiaries or Holdings and
(2) the "Notes" mean the New Notes and the Old Notes, in each case, outstanding at any given time and issued under the Indenture.

These New Notes will be unsecured obligations of TransDigm, ranking subordinate in right of payment to all Senior Debt of the Company.

TransDigm will issue the New Notes in fully registered form in denominations of $1,000 and integral multiples of $1,000. The Trustee will initially act as Paying Agent and Registrar. The New Notes may be presented for registration of transfer and exchange at the offices of the Registrar. TransDigm may change any Paying Agent and Registrar without notice to holders of the New Notes (the "Holders"). TransDigm will pay principal, and premium, if any, on the New Notes at the Trustee's corporate office in New York, New York. At TransDigm's option, interest also may be paid by mailing a check to the Holders registered address. Any Old Notes that remain outstanding after the completion of the Exchange Offer, together with the New Notes issued as part of the Exchange Offer, will be treated as a single class of securities under the Indenture.

PRINCIPAL, MATURITY AND INTEREST

The Notes are limited in aggregate principal amount to $200.0 million, of which up to $125.0 million in aggregate principal amount of the Notes will be outstanding immediately following the Exchange Offer. The Notes will mature on December 1, 2008. Additional Notes may be issued from time to time, subject to the limitations set forth under "--Certain Covenants--Limitation on Incurrence of Additional Indebtedness." Interest on the Notes will accrue at the rate of 10 3/8% per annum and will be payable semiannually in cash on each June 1 and December 1, commencing on June 1, 1999. TransDigm will make interest payments to the persons who are registered Holders at the close of business on the May 15 and November 15 immediately preceding the applicable interest payment date. Interest on the New Notes will accrue from December 3, 1998 or from the date of the last payment of interest on the Old Notes, whichever is later. No additional interest will be paid on Old Notes tendered and accepted for exchange.

The Notes do not contain any mandatory sinking fund.

REDEMPTION

OPTIONAL REDEMPTION. Except as described below, these New Notes are not redeemable before December 1, 2003. Thereafter, TransDigm may redeem the New Notes at its option, in whole or in part, upon not less than 30 nor more than 60 days' notice, at the following redemption prices, in each

74

case, expressed as percentages of the principal amount of the Notes, if redeemed during the twelve month period commencing on December 1 of the year set forth below.

YEAR                                                                                PERCENTAGE
----------------------------------------------------------------------------------  -----------
2003..............................................................................     105.188%
2004..............................................................................     103.458%
2005..............................................................................     101.729%
2006 and thereafter...............................................................     100.000%

In addition, TransDigm must pay all accrued and unpaid interest on the Notes redeemed.

OPTIONAL REDEMPTION UPON EQUITY OFFERINGS. On one or more occasions prior to December 1, 2001, TransDigm may use the net cash proceeds of one or more Equity Offerings to redeem up to 35% of the principal amount of the Notes, including the New Notes, issued under the Indenture at a redemption price of 110.375% of the principal amount of the Notes, plus accrued and unpaid interest on the notes, if any, to the date of redemption; PROVIDED that:

(1) at least 65% of the aggregate principal amount of Notes issued under the Indenture remains outstanding immediately after any such redemption; and

(2) TransDigm makes such redemption not more than 120 days after the consummation of such Equity Offering.

SELECTION AND NOTICE OF REDEMPTION

In the event that TransDigm chooses to redeem less than all of the Notes, selection of the Notes for redemption will be made by the Trustee either:

(1) in compliance with the requirements of the principal national securities exchange, if any, on which such Notes are listed; or

(2) on a PRO RATA basis, by lot or by such method as the Trustee shall deem fair and appropriate. No Notes of a principal amount of $1,000 or less shall be redeemed in part.

If a partial redemption is made with the proceeds of an Equity Offering, the Trustee will select the Notes only on a PRO RATA basis or on as nearly a PRO RATA basis as is practicable. Notice of redemption will be mailed by first-class mail at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. On and after the redemption date, interest will cease to accrue on Notes or portions thereof called for redemption as long as TransDigm has deposited with the Paying Agent funds in satisfaction of the applicable redemption price.

SUBORDINATION

The payment of all Obligations on the Notes is subordinated in right of payment to the prior payment in full in cash or Cash Equivalents of all Obligations on Senior Debt of TransDigm including its obligations under the New Credit Facility.

The holders of Senior Debt will be entitled to receive payment in full in cash of all Obligations due in respect of Senior Debt, including interest after the commencement of any bankruptcy or other like proceeding at the rate specified in the applicable Senior Debt whether or not such interest is an allowed claim in any such proceeding, before the Holders of Notes will be entitled to receive any payment with respect to the Notes in the event of any distribution to creditors of TransDigm:

(1) in a liquidation or dissolution of TransDigm;

(2) in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to TransDigm or its property;

75

(3) in an assignment for the benefit of creditors; or

(4) in any marshalling of TransDigm's assets and liabilities.

TransDigm also may not make any payment in respect of the Notes if:

(1) a payment default on Designated Senior Debt occurs and is continuing; or

(2) any other default occurs and is continuing on Designated Senior Debt that permits holders of the Designated Senior Debt to accelerate its maturity and the Trustee receives a notice of such default (a "Payment Blockage Notice") from the Representative of any Designated Senior Debt.

Payments on the Notes may and shall be resumed:

(1) in the case of a payment default, upon the date on which such default is cured or waived; and

(2) in case of a nonpayment default, the earlier of the date on which such nonpayment default is cured or waived (so long as no other event of default exists) or 180 days after the date on which the applicable Payment Blockage Notice is received, unless the maturity of any Designated Senior Debt has been accelerated.

No new Payment Blockage Notice may be delivered unless and until 360 days have elapsed since the effectiveness of the immediately prior Payment Blockage Notice.

No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice unless such default shall have been cured or waived for a period of not less than 90 days.

TransDigm must promptly notify holders of Senior Debt if payment of the Notes is accelerated because of an Event of Default.

As a result of the subordination provisions described above, in the event of a bankruptcy, liquidation or reorganization of TransDigm, Holders of these Notes may recover less ratably than creditors of TransDigm who are holders of Senior Debt. See "Risk Factors--Subordination."

At January 1, 1999 on a pro forma basis as if the aquisition of ZMP and the related borrowings under the New Credit Facility had occurred on January 1, 1999, the aggregate principal amount of Senior Debt outstanding of TransDigm and Holdings would have been $133.0 million and $153.2 million, respectively.

GUARANTEE

The obligations of the Company under the Notes and the Indenture will be fully and unconditionally guaranteed (the "Guarantees") on a senior subordinated basis and on a joint and several basis by Holdings and all of the direct and indirect Domestic Restricted Subsidiaries of TransDigm. The Guarantees will be subordinated in right of payment to all Senior Debt of Holdings and the Domestic Restricted Subsidiaries, respectively, to the same extent that the Notes are subordinated to Senior Debt of TransDigm. Since Holdings is a holding company with no significant operations, the Guarantee by Holdings provides little, if any, additional credit support for the Notes, and investors should not rely on the Guarantee by Holdings in evaluating an investment in the Notes.

CHANGE OF CONTROL

If a Change of Control occurs, each Holder will have the right to require that TransDigm purchase all or a portion of such Holder's Notes pursuant to the offer described below (the "Change of Control Offer"), at a purchase price equal to 101% of the principal amount of the Notes plus accrued interest to the date of purchase. Within 30 days following the date upon which the Change of Control occurred, TransDigm must send, by first class mail, a notice to each Holder, which notice shall govern the terms

76

of the Change of Control Offer. Such notice shall state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is mailed, other than as may be required by law (the "Change of Control Payment Date"). Holders electing to have a Note purchased pursuant to a Change of Control Offer will be required to surrender the Note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third business day prior to the Change of Control Payment Date.

Prior to the mailing of the notice referred to above, but in any event within 30 days following any Change of Control, TransDigm covenants to:

(1) repay in full all Indebtedness under the New Credit Facility and all other Senior Debt the terms of which require repayment upon a Change of Control; or

(2) obtain the requisite consents under the New Credit Facility and all such other Senior Debt to permit the repurchase of the Notes as provided below. TransDigm's failure to comply with the covenant described in the immediately preceding sentence shall constitute an Event of Default described in clause
(3) and not in clause (2) under "Events of Default" below.

TransDigm will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner in compliance with the Indenture.

If a Change of Control Offer is made, there can be no assurance that TransDigm will have available funds sufficient to pay the Change of Control purchase price for all the Notes that might be delivered by Holders seeking to accept the Change of Control Offer. In the event TransDigm is required to purchase outstanding Notes pursuant to a Change of Control Offer, TransDigm expects that it would seek third party financing to the extent it does not have available funds to meet its purchase obligations. However, there can be no assurance that TransDigm would be able to obtain such financing.

You should note that this provision will not protect you from the adverse aspects of a highly leveraged transaction, reorganization, restructuring, merger or similar transaction.

TransDigm will comply with the requirements of Rule 14e-1 under the Exchange Act to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that TransDigm complies with the provisions of any such securities laws or regulations, TransDigm shall not be deemed to have breached its obligations under the "Change of Control" provisions of the Indenture.

CERTAIN COVENANTS

The Indenture contains, among others, the following covenants:

LIMITATION ON INCURRENCE OF ADDITIONAL INDEBTEDNESS. TransDigm will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively "incur") any Indebtedness, other than Permitted Indebtedness; PROVIDED, HOWEVER, that if no Default or Event of Default shall have occurred and be continuing at the time of or as a consequence of the incurrence of any such Indebtedness, TransDigm and the Guarantors may incur Indebtedness, including, without limitation, Acquired Indebtedness, and Restricted Subsidiaries of TransDigm that are not Guarantors may incur Acquired Indebtedness, in each case if on the date of the incurrence of such Indebtedness, after giving effect to the incurrence thereof, the Consolidated Fixed Charge Coverage Ratio of TransDigm would have been greater than 2.0 to 1.0.

77

LIMITATION ON RESTRICTED PAYMENTS. TransDigm will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly:

(1) declare or pay any dividend or make any distribution (other than dividends or distributions payable in Qualified Capital Stock of TransDigm) on or in respect of shares of TransDigm's Capital Stock to holders of such Capital Stock;

(2) purchase, redeem or otherwise acquire or retire for value any Capital Stock of TransDigm or any direct or indirect parent of TransDigm or any warrants, rights or options to purchase or acquire shares of any class of such Capital Stock;

(4) make any Investment, other than Permitted Investments (each of the foregoing actions set forth in clauses (1), (2), (3) and (4) being referred to as a "Restricted Payment");

if at the time of such Restricted Payment or immediately after giving effect thereto:

(i) a Default or an Event of Default shall have occurred and be continuing; or

(ii) TransDigm is not able to incur at least $1.00 of additional Indebtedness, other than Permitted Indebtedness, in compliance with the "Limitation on Incurrence of Additional Indebtedness" covenant; or

(iii) the aggregate amount of Restricted Payments, including such proposed Restricted Payment, made subsequent to the Issue Date, other than Restricted Payments made pursuant to clauses (2)(i), (3), (4), (5), (6),
(7), (8), (9) and (10) of the following paragraph, shall exceed the sum, without duplication, of:

(w) 50% of the cumulative Consolidated Net Income, or if cumulative Consolidated Net Income shall be a loss, minus 100% of such loss, of TransDigm earned subsequent to the beginning of the first fiscal quarter commencing after the Issue Date and on or prior to the date the Restricted Payment occurs (the "Reference Date") (treating such period as a single accounting period); plus

(x) 100% of the aggregate net cash proceeds, including the fair market value of property other than cash that would constitute Marketable Securities or a Permitted Business, received by TransDigm from any Person, other than a Subsidiary of TransDigm, from the issuance and sale subsequent to the Issue Date and on or prior to the Reference Date of Qualified Capital Stock of TransDigm; plus

(y) without duplication of any amounts included in clause (iii)(x) above, 100% of the aggregate net cash proceeds of any equity contribution received by TransDigm from a holder of TransDigm's Capital Stock and excluding, in the case of clauses (iii)(x) and (y), any net cash proceeds from an Equity Offering to the extent used to redeem the Notes in compliance with the provisions set forth under "--Redemption--Optional Redemption Upon Equity Offerings"; plus

(z) 100% of the aggregate net proceeds, including the fair market value of property other than cash that would constitute Marketable Securities or a Permitted Business, of any (A) sale or other disposition of any Investment, other than a Permitted Investment, made by TransDigm and its Restricted Subsidiaries or (B) dividend from, or the sale of the stock of, an Unrestricted Subsidiary.

78

Notwithstanding the foregoing, the provisions set forth in the immediately preceding paragraph do not prohibit:

(1) the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of declaration of such dividend or notice of such redemption if the dividend or payment of the redemption price, as the case may be, would have been permitted on the date of declaration or notice;

(2) if no Default or Event of Default shall have occurred and be continuing or shall occur as a consequence thereof, the acquisition of any shares of Capital Stock of TransDigm (the "Retired Capital Stock") either (A) solely in exchange for shares of Qualified Capital Stock of TransDigm (the "Refunding Capital Stock") or (B) through the application of net proceeds of a substantially concurrent sale for cash, other than to a Subsidiary of TransDigm, of shares of Qualified Capital Stock of TransDigm and, in the case of subclause (A) of this clause (2), if immediately prior to the retirement of the Retired Capital Stock the declaration and payment of dividends thereon was permitted under clause (5) of this paragraph, the declaration and payment of dividends on the Refunding Capital Stock in an aggregate amount per year no greater than the aggregate amount of dividends per annum that was declarable and payable on such Retired Capital Stock immediately prior to such retirement; PROVIDED that at the time of the declaration of any such dividends on the Refunding Capital Stock, no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof;

(3) if no Default or Event of Default shall have occurred and be continuing, the acquisition of any Indebtedness of TransDigm that is subordinate or junior in right of payment to the Notes either (A) solely in exchange for shares of Qualified Capital Stock of TransDigm, or (B) through the application of net proceeds of a substantially concurrent sale for cash, other than to a Subsidiary of TransDigm, of (a) shares of Qualified Capital Stock of TransDigm or (b) Refinancing Indebtedness;

(5) payments to Holdings for the purpose of permitting, and in an amount equal to the amount required to permit, Holdings to redeem or repurchase Holdings' common equity or options in respect thereof, in each case in connection with the repurchase provisions of employee stock option or stock purchase agreements or other agreements to compensate management employees; PROVIDED that all such redemptions or repurchases pursuant to this clause (5) shall not exceed $2.0 million in any fiscal year, which amount shall be increased by the amount of any net cash proceeds received from the sale since the Issue Date of Capital Stock, other than Disqualified Capital Stock, to members of TransDigm's management team that have not otherwise been applied to the payment of Restricted Payments pursuant to the terms of clause (iii) of the immediately preceding paragraph and by the cash proceeds of any "key-man" life insurance policies which are used to make such redemptions or repurchases) since the Issue Date; PROVIDED, FURTHER, that the cancellation of Indebtedness owing to TransDigm from members of management of TransDigm or any of its Restricted Subsidiaries in connection with any repurchase of Capital Stock of Holdings, or warrants or options or rights to acquire such Capital Stock, will not be deemed to constitute a Restricted Payment under the Indenture;

79

(6) the making of distributions, loans or advances to Holdings in an amount not to exceed $1.0 million PER ANNUM in order to permit Holdings to pay the ordinary operating expenses of Holdings, including, without limitation, directors' fees, indemnification obligations, professional fees and expenses;

(7) payments to Holdings in respect of taxes pursuant to the terms of the Tax Allocation Agreement as in effect on the Issue Date and as amended from time to time pursuant to amendments that do not increase the amounts payable by TransDigm or any of its Restricted Subsidiaries thereunder;

(8) repurchases of Capital Stock deemed to occur upon the exercise of stock options if such Capital Stock represents a portion of the exercise price thereof;

(9) other Restricted Payments in an aggregate amount not to exceed $7.5 million; and

In determining the aggregate amount of Restricted Payments made subsequent to the Issue Date in accordance with clause (iii) of the immediately preceding paragraph, (a) amounts expended pursuant to clauses (1) and (2)(ii) shall be included in such calculation, PROVIDED such expenditures pursuant to clause (5) shall not be included to the extent of the cash proceeds received by TransDigm from any "key-man" life insurance policies and (b) amounts expended pursuant to clauses (2)(i), (3), (4), (5), (6), (7), (8), (9) and (10) shall be excluded from such calculation.

LIMITATION ON ASSET SALES. TransDigm will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) TransDigm or the applicable Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value of the assets sold or otherwise disposed of, as determined in good faith by TransDigm's Board of Directors;

(2) at least 75% of the consideration received by TransDigm or the Restricted Subsidiary, as the case may be, from such Asset Sale shall be in the form of cash or Cash Equivalents and is received at the time of such disposition; PROVIDED that the amount of:

(a) any liabilities, as shown on TransDigm's or such Restricted Subsidiary's most recent balance sheet, of TransDigm or any such Restricted Subsidiary, other than liabilities that are by their terms subordinated to the Notes, that are assumed by the transferee of any such assets;

(b) any notes or other obligations received by TransDigm or any such Restricted Subsidiary from such transferee that are converted by TransDigm or such Restricted Subsidiary into cash within 90 days of the receipt thereof, to the extent of the cash received; and

(c) any Designated Noncash Consideration received by TransDigm or any of its Restricted Subsidiaries in such Asset Sale having an aggregate fair market value, taken together with all other Designated Noncash Consideration received pursuant to this clause (c) that is at that time outstanding, not to exceed 5% of Total Assets at the time of the receipt of such Designated Noncash Consideration, with the fair market value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value, shall be deemed to be cash for the purposes of this provision or for purposes of the second paragraph of this covenant; and

(3) upon the consummation of an Asset Sale, TransDigm shall apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within 365 days of receipt thereof either (A) to prepay any Senior Debt, or Indebtedness of a Restricted Subsidiary that is not a Guarantor and, in the case of any such Indebtedness under any revolving credit facility, effect a corresponding reduction in the availability under such revolving credit facility, or effect a

80

permanent reduction in the availability under such revolving credit facility regardless of the fact that no prepayment is required in order to do so, in which case no prepayment should be required, (B) to reinvest in Productive Assets, or (C) a combination of prepayment and investment permitted by the foregoing clauses (3)(A) and (3)(B). Pending the final application of any such Net Cash Proceeds, TransDigm or such Restricted Subsidiary may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Cash Proceeds in Cash Equivalents. On the 366th day after an Asset Sale or such earlier date, if any, as the Board of Directors of TransDigm or of such Restricted Subsidiary determines not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses (3)(A), (3)(B) and (3)(C) of the preceding sentence (each, a "Net Proceeds Offer Trigger Date"), such aggregate amount of Net Cash Proceeds which have not been applied on or before such Net Proceeds Offer Trigger Date as permitted in clauses (3)(A), (3)(B) and (3)(C) of the next preceding sentence (each a "Net Proceeds Offer Amount") shall be applied by TransDigm or such Restricted Subsidiary to make an offer to purchase (the "Net Proceeds Offer") on a date (the "Net Proceeds Offer Payment Date") not less than 30 nor more than 60 days following the applicable Net Proceeds Offer Trigger Date, from all Holders on a PRO RATA basis, the maximum amount of Notes that may be purchased with the Net Proceeds Offer Amount at a price equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon, if any, to the date of purchase; PROVIDED, HOWEVER, that if at any time any non-cash consideration (including any Designated Noncash Consideration) received by TransDigm or any Restricted Subsidiary of TransDigm, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall be applied in accordance with this covenant. Notwithstanding the foregoing, if a Net Proceeds Offer Amount is less than $10.0 million, the application of the Net Cash Proceeds constituting such Net Proceeds Offer Amount to a Net Proceeds Offer may be deferred until such time as such Net Proceeds Offer Amount plus the aggregate amount of all Net Proceeds Offer Amounts arising subsequent to the Net Proceeds Offer Trigger Date relating to such initial Net Proceeds Offer Amount from all Asset Sales by TransDigm and its Restricted Subsidiaries aggregates at least $10.0 million, at which time TransDigm or such Restricted Subsidiary shall apply all Net Cash Proceeds constituting all Net Proceeds Offer Amounts that have been so deferred to make a Net Proceeds Offer (the first date the aggregate of all such deferred Net Proceeds Offer Amounts is equal to $10.0 million or more shall be deemed to be a Net Proceeds Offer Trigger Date).

Notwithstanding the immediately preceding paragraph, TransDigm and its Restricted Subsidiaries will be permitted to consummate an Asset Sale without complying with such paragraph to the extent that:

(1) at least 75% of the consideration for such Asset Sale constitutes Productive Assets, cash, Cash Equivalents and/or Marketable Securities; and

(2) such Asset Sale is for fair market value; PROVIDED that any consideration consisting of cash, Cash Equivalents and/or Marketable Securities received by TransDigm or any of its Restricted Subsidiaries in connection with any Asset Sale permitted to be consummated under this paragraph shall constitute Net Cash Proceeds subject to the provisions of the preceding paragraph.

Each Net Proceeds Offer will be mailed to the record Holders as shown on the register of Holders within 30 days following the Net Proceeds Offer Trigger Date, with a copy to the Trustee, and shall comply with the procedures set forth in the Indenture. Upon receiving notice of the Net Proceeds Offer, Holders may elect to tender their Notes in whole or in part in integral multiples of $1,000 in exchange for cash. To the extent Holders properly tender Notes in an amount exceeding the Net Proceeds Offer Amount, Notes of tendering Holders will be purchased on a PRO RATA basis, based on

81

amounts tendered. A Net Proceeds Offer shall remain open for a period of 20 business days or such longer period as may be required by law. To the extent that the aggregate amount of Notes tendered pursuant to a Net Proceeds Offer is less than the Net Proceeds Offer Amount, TransDigm may use any remaining Net Proceeds Offer Amount for general corporate purposes or for any other purpose not prohibited by the Indenture. Upon completion of any such Net Proceeds Offer, the Net Proceeds Offer Amount shall be reset at zero.

TransDigm will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the "Asset Sale" provisions of the Indenture, TransDigm shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the "Asset Sale" provisions of the Indenture by virtue of its compliance with the applicable securities laws and regulations.

LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES. TransDigm will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary of TransDigm to:

(1) pay dividends or make any other distributions on or in respect of its Capital Stock;

(2) make loans or advances or pay any Indebtedness or other obligation owed to TransDigm or any other Restricted Subsidiary of TransDigm; or

(3) transfer any of its property or assets to TransDigm or any other Restricted Subsidiary of TransDigm, except for such encumbrances or restrictions existing under or by reason of:

(a) applicable law;

(b) the Indenture;

(c) non-assignment provisions of any contract or any lease of any Restricted Subsidiary of TransDigm entered into in the ordinary course of business;

(d) any instrument governing Acquired Indebtedness, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired;

(e) the New Credit Facility;

(f) agreements existing on the Issue Date to the extent and in the manner such agreements are in effect on the Issue Date;

(g) restrictions on the transfer of assets subject to any Lien permitted under the Indenture imposed by the holder of such Lien;

(h) restrictions imposed by any agreement to sell assets or Capital Stock permitted under the Indenture to any Person pending the closing of such sale;

(i) any agreement or instrument governing Capital Stock of any Person that is acquired;

(j) any Purchase Money Note or other Indebtedness or other contractual requirements of a Securitization Entity in connection with a Qualified Securitization Transaction; provided that such restrictions apply only to such Securitization Entity;

(k) other Indebtedness or Permitted Subsidiary Preferred Stock outstanding on the Issue Date or permitted to be issued or incurred under the Indenture; PROVIDED that any such restrictions are

82

ordinary and customary with respect to the type of Indebtedness being incurred or Preferred Stock being issued (under the relevant circumstances);

(l) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business; and

(m) any encumbrances or restrictions imposed by any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (a) through (l) above; PROVIDED that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of TransDigm's Board of Directors (evidenced by a Board Resolution) whose judgment shall be conclusively binding, not materially more restrictive with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing.

LIMITATION ON PREFERRED STOCK OF RESTRICTED SUBSIDIARIES. TransDigm will not permit any of its Restricted Subsidiaries to issue any Preferred Stock, other than to TransDigm or to a Restricted Subsidiary of TransDigm, or permit any Person, other than TransDigm or a Restricted Subsidiary of TransDigm, to own any Preferred Stock of any Restricted Subsidiary of TransDigm, other than Permitted Subsidiary Preferred Stock. The provisions of this covenant will not apply to any of the Guarantors.

LIMITATION ON LIENS. TransDigm will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly create, incur, assume or permit or suffer to exist any Liens of any kind against or upon any property or assets or any proceeds therefrom, of TransDigm or any of its Restricted Subsidiaries whether owned on the Issue Date or acquired after the Issue Date, in each case to secure Indebtedness or trade payables, unless:

(1) in the case of Liens securing Indebtedness that is expressly subordinate or junior in right of payment to the Notes, the Notes are secured by a Lien on such property, assets or proceeds that is senior in priority to such Liens; and

(2) in all other cases, the Notes are equally and ratably secured, except for:

(a) Liens existing as of the Issue Date to the extent and in the manner such Liens are in effect on the Issue Date;

(b) Liens securing Senior Debt;

(c) Liens securing the Notes;

(d) Liens of TransDigm or a Wholly Owned Restricted Subsidiary of TransDigm on assets of any Restricted Subsidiary of TransDigm;

(e) Liens securing Refinancing Indebtedness which is incurred to Refinance any Indebtedness that was secured by a Lien permitted under the Indenture and which has been incurred in accordance with the provisions of the Indenture; PROVIDED, HOWEVER, that such Liens do not extend to or cover any categories of property or assets of TransDigm or any of its Restricted Subsidiaries not securing the Indebtedness so Refinanced; and

(f) Permitted Liens.

PROHIBITION ON INCURRENCE OF SENIOR SUBORDINATED DEBT. TransDigm will not, and will not permit any Restricted Subsidiary that is a Guarantor to, incur or suffer to exist Indebtedness that is senior in right of payment to the Notes or such Guarantor's Guarantee, as the case may be, and subordinate in right of payment to any other Indebtedness of TransDigm or such Guarantor, as the case may be.

83

MERGER CONSOLIDATION AND SALE OF ASSETS. TransDigm will not, in a single transaction or series of related transactions, consolidate or merge with or into any Person, or sell, assign, transfer, lease, convey or otherwise dispose of or cause or permit any Restricted Subsidiary of TransDigm to sell, assign, transfer, lease, convey or otherwise dispose of, all or substantially all of TransDigm's assets, in each case, determined on a consolidated basis for TransDigm and TransDigm's Restricted Subsidiaries, whether as an entirety or substantially as an entirety to any Person unless:

(1) either:

(a) TransDigm shall be the surviving or continuing corporation; or

(b) the Person, if other than TransDigm, formed by such consolidation or into which TransDigm is merged or the Person which acquires by sale, assignment, transfer, lease, conveyance or other disposition the properties and assets of TransDigm and of TransDigm's Restricted Subsidiaries substantially as an entirety (the "Surviving Entity"):

(x) shall be a corporation organized and validly existing under the laws of the United States or any State thereof or the District of Columbia; and

(y) shall expressly assume, by supplemental indenture in form and substance satisfactory to the Trustee, executed and delivered to the Trustee, the due and punctual payment of the principal of, and premium, if any, and interest on all of the Notes and the performance of every covenant of the Notes, the Indenture and the Registration Rights Agreement on the part of TransDigm to be performed or observed;

(2) except in the case of a merger of TransDigm with or into a Wholly Owned Restricted Subsidiary of TransDigm and except in the case of a merger entered into solely for the purpose of reincorporating TransDigm in another jurisdiction, immediately after giving effect to such transaction and the assumption contemplated by clause (1)(b)(y) above (including giving effect to any Indebtedness and Acquired Indebtedness incurred in connection with or in respect of such transaction), TransDigm or such Surviving Entity, as the case may be, shall be able to incur at least $1.00 of additional Indebtedness pursuant to the "Limitation on Incurrence of Additional Indebtedness" covenant;

(3) except in the case of a merger of TransDigm with or into a Wholly Owned Restricted Subsidiary of TransDigm and except in the case of a merger entered into solely for the purpose of reincorporating TransDigm in another jurisdiction, immediately after giving effect to such transaction and the assumption contemplated by clause (1)(b)(y) above, including, without limitation, giving effect to any Indebtedness and Acquired Indebtedness incurred and any Lien granted in connection with or in respect of the transaction, no Default or Event of Default shall have occurred or be continuing; and

(4) TransDigm or the Surviving Entity shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture comply with the applicable provisions of the Indenture and that all conditions precedent in the Indenture relating to such transaction have been satisfied.

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries of TransDigm the Capital Stock of which constitutes all or substantially all of the properties and assets of TransDigm, shall be deemed to be the transfer of all or substantially all of the properties and assets of TransDigm. However, transfer of assets between or among TransDigm and its Restricted Subsidiaries will not be subject to the foregoing covenant.

84

The Indenture provides that upon any consolidation, combination or merger or any transfer of all or substantially all of the assets of TransDigm in accordance with the foregoing, in which TransDigm is not the continuing corporation, the successor Person formed by such consolidation or into which TransDigm is merged or to which such conveyance, lease or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, TransDigm under the Indenture and the Notes with the same effect as if such surviving entity had been named as such and that, in the event of a conveyance, lease or transfer, the conveyor, lessor or transferor will be released from the provisions of the Indenture.

LIMITATIONS ON TRANSACTIONS WITH AFFILIATES. TransDigm will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to occur any transaction or series of related transactions, including, without limitation, the purchase, sale, lease or exchange of any property or the rendering of any service, with, or for the benefit of, any of its Affiliates (an "Affiliate Transaction"), other than Affiliate Transactions on terms that are not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm's-length basis from a Person that is not an Affiliate of TransDigm; PROVIDED, HOWEVER, that for a transaction or series of related transactions with an aggregate value of $2.5 million or more, at TransDigm's option, either:

(1) a majority of the disinterested members of the Board of Directors of TransDigm shall determine in good faith that such Affiliate Transaction is on terms that are not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm's-length basis from a Person that is not an Affiliate of TransDigm or

(2) the Board of Directors of TransDigm or any such Restricted Subsidiary party to such Affiliate Transaction shall have received an opinion from a nationally recognized investment banking, appraisal or accounting firm that such Affiliate Transaction is on terms not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm's-length basis from a Person that is not an Affiliate of TransDigm;

and PROVIDED, FURTHER, that for an Affiliate Transaction with an aggregate value of $10.0 million or more the Board of Directors of TransDigm or any such Restricted Subsidiary party to such Affiliate Transaction shall have received an opinion from a nationally recognized investment banking, appraisal or accounting firm that such Affiliate Transaction is on terms not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm's-length basis from a Person that is not an Affiliate of TransDigm.

The restrictions set forth in the first paragraph of this covenant shall not apply to:

(1) reasonable fees and compensation paid to, and indemnity provided on behalf of, officers, directors, employees or consultants of TransDigm or any Restricted Subsidiary of TransDigm as determined in good faith by TransDigm's Board of Directors or senior management;

(2) transactions exclusively between or among TransDigm and any of its Restricted Subsidiaries or exclusively between or among such Restricted Subsidiaries, provided such transactions are not otherwise prohibited by the Indenture;

(3) any agreement as in effect as of the Issue Date or any amendment thereto or any transaction contemplated thereby, including pursuant to any amendment thereto, in any replacement agreement thereto so long as any such amendment or replacement agreement is not more disadvantageous to the Holders in any material respect than the original agreement as in effect on the Issue Date;

(4) Restricted Payments or Permitted Investments permitted by the Indenture;

(5) transactions effected as part of a Qualified Securitization Transaction;

85

(6) the payment of customary annual management, consulting and advisory fees and related expenses to the Permitted Holders and their Affiliates made pursuant to any financial advisory, financing, underwriting or placement agreement or in respect of other investment banking activities, including, without limitation, in connection with acquisitions or divestitures which are approved by the Board of Directors of TransDigm or such Restricted Subsidiary in good faith;

(7) payments or loans to employees or consultants that are approved by the Board of Directors of TransDigm in good faith;

(8) sales of Qualified Capital Stock;

(9) the existence of, or the performance by TransDigm or any of its Restricted Subsidiaries of its obligations under the terms of, any stockholders agreement, including any registration rights agreement or purchase agreement related thereto, to which it is a party as of the Issue Date and any similar agreements which it may enter into thereafter; PROVIDED, HOWEVER, that the existence of, or the performance by TransDigm or any of its Restricted Subsidiaries of obligations under, any future amendment to any such existing agreement or under any similar agreement entered into after the Issue Date shall only be permitted by this clause (9) to the extent that the terms of any such amendment or new agreement are not disadvantageous to the Holders of the Notes in any material respect; and

(10) transactions permitted by and complying with, the provisions of the "Merger, Consolidation and Sale of Assets" covenant.

FUTURE GUARANTEES BY RESTRICTED SUBSIDIARIES. TransDigm will not create or acquire another Domestic Restricted Subsidiary unless such Domestic Restricted Subsidiary executes and delivers a supplemental indenture to the Indenture, providing for a senior subordinated guarantee of payment of the Notes by such Restricted Subsidiary (the "Guarantee").

Notwithstanding the foregoing, any such Guarantee by a Domestic Restricted Subsidiary of the Notes shall provide by its terms that it shall be automatically and unconditionally released and discharged, without any further action required on the part of the Trustee or any Holder, upon any sale or other disposition, by merger or otherwise, to any Person which is not a Restricted Subsidiary of TransDigm of all of TransDigm's Capital Stock in, or all or substantially all of the assets of, such Domestic Restricted Subsidiary; PROVIDED that such sale or disposition of such Capital Stock or assets is otherwise in compliance with the terms of the Indenture. A form of such Guarantee will be attached as an exhibit to the Indenture.

CONDUCT OF BUSINESS. The Indenture provides that TransDigm will not, and will not permit any of its Restricted Subsidiaries to, engage in any businesses a majority of whose revenues are not derived from businesses that are the same or reasonably similar, ancillary or related to, or a reasonable extension, development or expansion of, the businesses in which TransDigm and its Restricted Subsidiaries are engaged on the Issue Date.

REPORTS TO HOLDERS. The Indenture provides that, whether or not required by the rules and regulations of the Commission, so long as any Notes are outstanding, TransDigm will furnish to the Holders of Notes:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if TransDigm were required to file those Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" that describes the financial condition and results of operations of TransDigm and its consolidated Subsidiaries, showing in reasonable detail, either on the face of the financial statements or in the footnotes thereto and in Management's Discussion and Analysis of Financial Condition and Results of Operations, the financial condition and results of operations of

86

TransDigm and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of TransDigm, and, with respect to the annual information only, a report thereon by TransDigm's certified independent accountants and

(2) all current reports that would be required to be filed with the Commission on Form 8-K if TransDigm were required to file such reports, in each case, within the time periods specified in the Commission's rules and regulations. For so long as Holdings is a guarantor of the Notes, the Indenture permits TransDigm to satisfy its obligations under this covenant by furnishing financial information relating to Holdings; PROVIDED that the same is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to Holdings, on the one hand, and the information relating to TransDigm and its Restricted Subsidiaries on a stand-alone basis, on the other hand.

In addition, following the consummation of this exchange offer, whether or not required by the rules and regulations of the Commission, TransDigm will file a copy of all those information and reports with the Commission for public availability within the time periods specified in the Commission's rules and regulations, unless the Commission will not accept such a filing, and make such information available to securities analysts and prospective investors upon request. In addition, TransDigm has agreed that, for so long as any Old Notes remain outstanding, it will furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d) (4) under the Securities Act.

EVENTS OF DEFAULT

The following events are defined in the Indenture as "Events of Default":

(1) the failure to pay interest on any Notes when the same becomes due and payable and the default continues for a period of 30 days, whether or not such payment shall be prohibited by the subordination provisions of the Indenture;

(2) the failure to pay the principal on any Notes, when such principal becomes due and payable, at maturity, upon redemption or otherwise, including the failure to make a payment to purchase Notes tendered pursuant to a Change of Control Offer or a Net Proceeds Offer on the date specified for such payment in the applicable offer to purchase and whether or not such payment shall be prohibited by the subordination provisions of the Indenture;

(3) a default in the observance or performance of any other covenant or agreement contained in the Indenture which default continues for a period of 30 days after TransDigm receives written notice specifying the default and demanding that such default be remedied from the Trustee or the Holders of at least 25% of the outstanding principal amount of the Notes, except in the case of a default with respect to the "Merger, Consolidation and Sale of Assets" covenant, which will constitute an Event of Default with such notice requirement but without such passage of time requirement;

(4) the failure to pay at final stated maturity, after giving effect to any applicable grace periods and any extensions of the grace periods, the principal amount of any Indebtedness of TransDigm or any Restricted Subsidiary of TransDigm other than a Securitization Entity, which failure continues for at least 20 days, or the acceleration of the final stated maturity of any such Indebtedness, which acceleration remains uncured or unrescinded for at least 20 days, if the aggregate principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final maturity or which has been accelerated, in each case, with respect to which the 20-day period described above has passed, aggregates $5.0 million or more at any time;

87

(5) one or more judgments in an aggregate amount in excess of $5.0 million shall have been rendered against TransDigm or any of its Significant Subsidiaries and such judgments remain undischarged, unpaid or unstayed for a period of 60 days after such judgment or judgments become final and non-appealable; or

(6) certain events of bankruptcy affecting TransDigm or any of its Significant Subsidiaries.

If an Event of Default, other than an Event of Default specified in clause
(6) above with respect to TransDigm, shall occur and be continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding Notes may declare the principal of and accrued interest on all the Notes to be due and payable by notice in writing to TransDigm and the Trustee specifying the respective Event of Default and that it is a "notice of acceleration" (the "Acceleration Notice"), and the same:

(1) shall become immediately due and payable or

(2) if there are any amounts outstanding under the New Credit Facility, shall become immediately due and payable upon the first to occur of an acceleration under the New Credit Facility or 5 business days after receipt by TransDigm and the Representative under the New Credit Facility of such Acceleration Notice but only if such Event of Default is then continuing. If an Event of Default specified in clause (6) above with respect to TransDigm occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest on all of the outstanding Notes shall IPSO FACTO become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

The Indenture provides that, at any time after a declaration of acceleration with respect to the Notes as described in the preceding paragraph, the Holders of a majority in principal amount of the Notes may rescind and cancel such declaration and its consequences:

(1) if the rescission would not conflict with any judgment or decree;

(2) if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration;

(3) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid;

(4) if TransDigm has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances; and

(5) in the event of the cure or waiver of an Event of Default of the type described in clause (6) of the description above of Events of Default, the Trustee shall have received an officers' certificate and an opinion of counsel that such Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

The Holders of a majority in principal amount of the Notes may waive any existing Default or Event of Default under the Indenture, and its consequences, except a default in the payment of the principal of or interest on any Notes.

Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture and under the TIA. Subject to the provisions of the Indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the Holders, unless such Holders have offered to the Trustee reasonable indemnity. Subject to all provisions of the Indenture and applicable law, the Holders of a majority in aggregate principal amount of the then outstanding Notes have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee.

88

Under the Indenture, TransDigm is required to provide an officers' certificate to the Trustee promptly upon any such officer obtaining knowledge of any Default or Event of Default (provided that such officers shall provide such certification at least annually whether or not they know of any Default or Event of Default) that has occurred and, if applicable, describe such Default or Event of Default and the status thereof.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

TransDigm may, at its option and at any time, elect to have its obligations discharged with respect to the outstanding Notes ("Legal Defeasance"). Such Legal Defeasance means that TransDigm shall be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes, except for:

(1) the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments are due;

(2) TransDigm's obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payments;

(3) the rights, powers, trust, duties and immunities of the Trustee and TransDigm's obligations in connection therewith; and

(4) the Legal Defeasance provisions of the Indenture.

In addition, TransDigm may, at its option and at any time, elect to have the obligations of the Company released with respect to certain covenants that are described in the Indenture ("Covenant Defeasance") and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the Notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, reorganization and insolvency events) described under "Events of Default" will no longer constitute an Event of Default with respect to the Notes.

In order to exercise either Legal Defeasance or Covenant Defeasance:

(1) TransDigm must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders cash in U.S. dollars, non-callable U.S. government obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on the Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be;

(2) in the case of Legal Defeasance, TransDigm shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that

(a) TransDigm has received from, or there has been published by the Internal Revenue Service a ruling or

(b) since the date of the Indenture, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance, TransDigm shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that the

89

Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit, other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing, or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under the Indenture, other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing, or any other material agreement or instrument to which TransDigm or any of its Subsidiaries is a party or by which TransDigm or any of its Subsidiaries is bound;

(6) TransDigm shall have delivered to the Trustee an officers' certificate stating that the deposit was not made by TransDigm with the intent of preferring the Holders over any other creditors of TransDigm or with the intent of defeating, hindering, delaying or defrauding any other creditors of TransDigm or others;

(7) TransDigm shall have delivered to the Trustee an officers' certificate and an opinion of counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with;

(8) TransDigm shall have delivered to the Trustee an opinion of counsel to the effect that:

(a) the trust funds will not be subject to any rights of holders of Senior Debt, including, without limitation, those arising under the Indenture; and

(b) after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally; and

(9) certain other customary conditions precedent are satisfied.

Notwithstanding the foregoing, the opinion of counsel required by clause (2) above with respect to a Legal Defeasance need not be delivered if all Notes not therefore delivered to the Trustee for cancellation (1) have become due and payable, or (2) will become due and payable on the maturity date within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of TransDigm.

SATISFACTION AND DISCHARGE

The Indenture will be discharged and will cease to be of further effect, except as to surviving rights or registration of transfer or exchange of the Notes, as expressly provided for in the Indenture, as to all outstanding Notes when

(1) either:

(a) all the Notes theretofore authenticated and delivered, except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by TransDigm and thereafter repaid to TransDigm or discharged from such trust, have been delivered to the Trustee for cancellation or

90

(b) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable, pursuant to an optional redemption notice or otherwise, and TransDigm has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the Notes to the date of deposit together with irrevocable instructions from TransDigm directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be; and

(2) TransDigm has paid all other sums payable under the Indenture by TransDigm,

The Trustee will acknowledge the satisfaction and discharge of the Indenture if TransDigm has delivered to the Trustee an officers' certificate and an opinion of counsel stating that all conditions precedent under the Indenture relating to the satisfaction and discharge of the Indenture have been complied with.

MODIFICATION OF THE INDENTURE

From time to time, TransDigm and the Trustee, without the consent of the Holders, may amend the Indenture for certain specified purposes, including curing ambiguities, defects or inconsistencies, so long as such change does not, in the opinion of the Trustee, adversely affect the rights of any of the Holders in any material respect. In formulating its opinion on such matters, the Trustee will be entitled to rely on such evidence as it deems appropriate, including, without limitation, solely on an opinion of counsel. Other modifications and amendments of the Indenture may be made with the consent of the Holders of a majority in principal amount of the then outstanding Notes issued under the Indenture, except that, without the consent of each Holder affected thereby, no amendment may:

(1) reduce the amount of Notes whose Holders must consent to an amendment;

(2) reduce the rate of or change or have the effect of changing the time for payment of interest, including defaulted interest, on any Notes;

(3) reduce the principal of or change or have the effect of changing the fixed maturity of any Notes, or change the date on which any Notes may be subject to redemption or reduce the redemption price therefor;

(4) make any Notes payable in money other than that stated in the Notes;

(5) make any change in the provisions of the Indenture protecting the right of each Holder to receive payment of principal of and interest on such Note on or after the due date thereof or to bring suit to enforce such payment, or permitting Holders of a majority in principal amount of Notes to waive Defaults or Events of Default;

(6) after the Company's obligation to purchase Notes arises thereunder, amend, change or modify in any material respect the obligation of TransDigm to make and consummate a Change of Control Offer in the event of a Change of Control or modify any of the provisions or definitions with respect thereto after a Change of Control has occurred; or

(7) modify or change any provision of the Indenture or the related definitions affecting the subordination or ranking of the Notes in a manner which adversely affects the Holders.

GOVERNING LAW

The Indenture provides that it and the Notes will be governed by, and construed in accordance with, the laws of the State of New York but without giving effect to applicable principles of conflicts of law to the extent that the application of the law of another jurisdiction would be required thereby.

91

THE TRUSTEE

The Indenture provides that, except during the continuance of an Event of Default, the Trustee will perform only such duties as are specifically set forth in the Indenture. During the existence of an Event of Default, the Trustee will exercise such rights and powers vested in it by the Indenture, and use the same degree of care and skill in its exercise as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

The Indenture and the provisions of the TIA contain certain limitations on the rights of the Trustee, should it become a creditor of TransDigm, to obtain payments of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. Subject to the TIA, the Trustee will be permitted to engage in other transactions; provided that if the Trustee acquires any conflicting interest as described in the TIA, it must eliminate such conflict or resign.

CERTAIN DEFINITIONS

Set forth below is a summary of certain of the defined terms used in the Indenture. Reference is made to the Indenture for the full definition of all such terms, as well as any other terms used herein for which no definition is provided.

"ACQUIRED INDEBTEDNESS" means Indebtedness of a Person or any of its Subsidiaries existing at the time such Person becomes a Restricted Subsidiary of TransDigm or at the time it merges or consolidates with or into TransDigm or any of its Subsidiaries or that is assumed in connection with the acquisition of assets from such Person and in each case not incurred by such Person in connection with, or in anticipation or contemplation of, such Person becoming a Restricted Subsidiary of TransDigm or such acquisition, merger or consolidation.

"AFFILIATE" means, with respect to any specified Person, any other Person who directly or indirectly through one or more intermediaries controls, or is controlled by, or is under common control with, such specified Person. The term "control" means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a Person, whether through the ownership of voting securities, by contract or otherwise; and the terms "controlling" and "controlled" have meanings correlative of the foregoing. Notwithstanding the foregoing, no Person, other than TransDigm or any Subsidiary of TransDigm, in whom a Securitization Entity makes an Investment in connection with a Qualified Securitization Transaction shall be deemed to be an Affiliate of TransDigm or any of its Subsidiaries solely by reason of such Investment.

"ASSET ACQUISITION" means (a) an Investment by TransDigm or any Restricted Subsidiary of TransDigm in any other Person pursuant to which such Person shall become a Restricted Subsidiary of TransDigm, or shall be merged with or into TransDigm or any Restricted Subsidiary of TransDigm, or (b) the acquisition by TransDigm or any Restricted Subsidiary of TransDigm of the assets of any Person, other than a Restricted Subsidiary of TransDigm, other than in the ordinary course of business.

"ASSET SALE" means any direct or indirect sale, issuance, conveyance, transfer, lease, other than operating leases entered into in the ordinary course of business, assignment or other transfer for value by TransDigm or any of its Restricted Subsidiaries in each case, including any Sale and Leaseback Transaction to any Person other than TransDigm or a Restricted Subsidiary of TransDigm of:

(1) any Capital Stock of any Restricted Subsidiary of TransDigm, or

(2) any other property or assets of TransDigm or any Restricted Subsidiary of TransDigm other than in the ordinary course of business; PROVIDED, HOWEVER, that Asset Sales or other dispositions shall not include:

(a) a transaction or series of related transactions for which TransDigm or its Restricted Subsidiaries receive aggregate consideration of less than $1.0 million;

REGISTRATION RIGHTS

THE SUMMARY SET FORTH BELOW OF CERTAIN PROVISIONS OF THE REGISTRATION RIGHTS AGREEMENT DOES NOT PURPORT TO BE COMPLETE AND IS SUBJECT TO, AND IS QUALIFIED IN ITS ENTIRETY BY, ALL THE PROVISIONS OF THE REGISTRATION RIGHTS AGREEMENT, A COPY OF WHICH HAS BEEN FILED AS AN EXHIBIT TO THE REGISTRATION STATEMENT.

TransDigm, the Initial Guarantors and the initial purchasers entered into the Registration Rights Agreement on December 3, 1998 (the "Issue Date") under the terms of which each of TransDigm and the Initial Guarantors agreed that they will, at their expense, for the benefit of holders of the Old Notes (the "Holders");

- within 60 days after the Issue Date (the "Filing Date"), file a registration statement on an appropriate registration form (the "Exchange Offer Registration Statement") with respect to a registered offer (the "Exchange Offer") to exchange the Old Notes for these New Notes, guaranteed on a senior subordinated basis by the Guarantors, which New Notes will have terms substantially identical in all material respects to the Old Notes; and

- cause the Exchange Offer Registration Statement to be declared effective under the Securities Act within 150 days after the Issue Date. Upon the Exchange Offer Registration Statement being declared effective, TransDigm will offer these New Notes in exchange for surrender of the Old Notes. TransDigm will keep the Exchange Offer open for not less than 30 days after the date notice of the Exchange Offer is mailed to the Holders. For each of the Old Notes surrendered to TransDigm in to the Exchange Offer, the Holder who surrendered that Old Note will receive a New Note having a principal amount equal to that of the surrendered Old Note. Interest on each New Note will accrue (1) from the later of (A) the last interest payment date on which interest was paid on the Old Note surrendered in exchange for the New Note, or (B) if the Old Note is surrendered for exchange on a date in a period which includes the record date for an interest payment date to occur on or after the date of that exchange and as to which interest will be paid, the date of that interest payment date or (2) if no interest has been paid on that Old Note, from the Issue Date.

If, (1) because of any change in law or in currently prevailing interpretations of the Staff of the Commission, TransDigm is not permitted to effect an exchange offer, (2) the Exchange Offer is not consummated by June 6, 1999 or (3) in certain circumstances, certain holders of unregistered Old Notes so request, or (4) in the case of any Holder that participates in the exchange offer, that Holder does not receive New Notes on the date of the exchange that may be sold without restriction under state and federal securities laws, other than due solely to the status of such Holder as an affiliate of the Company within the meaning of the Securities Act, then in each case, TransDigm will (A) promptly deliver to the Holders and the Trustee written notice of that event and (B) at its sole expense, (a) as promptly as practicable, file a shelf registration statement covering resales of the Old Notes (the "Shelf Registration Statement"); and (b) use its best efforts to keep effective the Shelf Registration Statement until the earlier of two years after its effective date or such time as all of the applicable Old Notes have been sold under the Shelf Registration Statement. TransDigm will, in the event that a Shelf Registration Statement is filed, provide to each Holder copies of the prospectus that is a part of the Shelf Registration Statement, notify each such Holder when the Shelf Registration Statement for the Old Notes has become effective and take other actions as are required to permit unrestricted resales of the Old Notes. A Holder that sells Old Notes relying on the Shelf Registration Statement will be required to be named as a selling security holder in the related prospectus and to deliver a prospectus to purchasers, will be subject to some of the civil liability provisions under the Securities Act in connection with those sales and will be bound by the provisions of the Registration Rights Agreement that are applicable to that Holder.

If TransDigm fails to comply with the above provisions or if the Exchange Offer Registration Statement or the Shelf Registration Statement fails to become effective, then, as liquidated damages,

111

additional interest (the "Additional Interest") shall become payable in respect of the Old Notes as follows:

- if (A) neither the Exchange Offer Registration Statement or Shelf Registration Statement is filed with the Commission on or prior to the applicable filing date or (B) notwithstanding that TransDigm has consummated or will consummate an exchange offer, TransDigm is required to file a Shelf Registration Statement and that Shelf Registration Statement is not filed on or prior to the date required by the Registration Rights Agreement, then commencing on the day after either such required filing dates, Additional Interest shall accrue on the principal amount of the Old Notes at a rate of 0.50% per year for the first 90 days immediately following each such filing date, such Additional Interest rate increasing by an additional 0.50% per year at the beginning of each subsequent 90-day period; or

- if (A) neither the Exchange Offer Registration Statement nor a Shelf Registration Statement is declared effective by the Commission on or prior to 90 days after the applicable filing deadline set for that filing in the Registration Rights Agreement or (B) notwithstanding that TransDigm has consummated or will consummate an exchange offer, TransDigm is required to file a Shelf Registration Statement and such Shelf Registration Statement is not declared effective by the Commission on or prior to the 90th day following the filing date deadline set for such filing in the Registration Rights Agreement, then, commencing on the day after such 90th day following the filing deadline set for such filing in the Registration Rights Agreement, Additional Interest shall accrue on the principal amount of the Old Notes at a rate of 0.50% per year for the first 90 days immediately following such date, that Additional Interest rate increasing by an additional 0.50% per year at the beginning of each subsequent 90-day period; or

- if (A) TransDigm has not exchanged New Notes for all Old Notes validly tendered in accordance with the terms of the exchange offer on or prior to the 185th day after the Issue Date or (B) if applicable, the Shelf Registration Statement ceases to be effective at any time prior to the second anniversary of the Issue Date, unless at that time all Old Notes have been disposed of under the Shelf Registration Statement, then Additional Interest shall accrue on the principal amount of the Old Notes at a rate of 0.50% per year for the first 90 days commencing on (x) the 185th day after the Issue Date, in the case of (A) above, or (y) the day such Shelf Registration Statement ceases to be effective in the case of (B) above, that Additional Interest rate increasing by an additional 0.50% per year at the beginning of each subsequent 90-day period;

However, the Additional Interest rate on the Old Notes may not accrue under more than one of the foregoing clauses at any one time and at no time shall the aggregate amount of Additional Interest accruing exceed in the aggregate 1.0% per year; and (1) upon the filing of the Exchange Offer Registration Statement or a Shelf Registration Statement, (2) upon the effectiveness of the Exchange Offer Registration Statement or a Shelf Registration Statement, or (3) upon the exchange of New Notes for all Old Notes tendered, or upon the effectiveness of the Shelf Registration Statement which had ceased to remain effective. Additional Interest on the Old Notes as a result of that clause, as the case may be, shall cease to accrue.

Any amounts of Additional Interest will be payable in cash on the original interest payment dates for the Old Notes.

112

BOOK-ENTRY; DELIVERY AND FORM

The certificates representing the New Notes will be issued in fully registered form without interest coupons.

Except as described herein under the heading "-Certificated Securities," New Notes will initially be represented by a permanent global New Note in fully registered form without interest coupons (the "Global Note") and will be deposited with the Trustee as custodian for DTC and registered in the name of a nominee of such depositary.

THE GLOBAL NOTE

TransDigm expects that according to procedures established by DTC (A) upon the issuance of the Global Note, DTC or its custodian will credit, on its internal system, the principal amount of the individual beneficial interests represented by the Global Note to the respective accounts of persons who have accounts with that depositary and (B) ownership of beneficial interests in the Global Note will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee and the records of participants. Ownership of beneficial interests in the Global Notes will be limited to persons who have accounts with DTC ("participants") or persons who hold interests through participants.

So long as DTC, or its nominee, is the registered owner or holder of the New Notes, DTC or that nominee, as the case may be, will be considered the sole owner or holder of the New Notes represented by the Global Note for all purposes under the Indenture. No beneficial owner of an interest in the Global Note will be able to transfer that interest except in accordance with DTC's procedures, in addition to those provided for under the Indenture.

Payments of the principal of, premium, if any, and interest on, the Global Note will be made to DTC or its nominee, as the case may be, as the registered owner of that Global Note. None of TransDigm, the Trustee or any paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Global Note or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

TransDigm expects that DTC or its nominee, upon receipt of any payment of principal, premium, if any, or interest on the Global Note, will credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the Global Note as shown on the records of DTC or its nominee. TransDigm also expects that payments by participants to owners of beneficial interests in the Global Note held through those participants will be governed by standing instructions and customary practice, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Those payments will be the responsibility of those participants.

Transfers between participants in DTC will be effected in the ordinary way through DTC's same-day funds system in accordance with DTC rules and will be settled in same-day funds. If a holder requires physical delivery of a Certificated Security for any reason, including to sell New Notes to persons in states that require physical delivery of the New Notes, or to pledge such securities, that holder must transfer its interest in the Global Note, in accordance with the normal procedures of DTC and with the procedures set forth in the Indenture.

DTC has advised TransDigm that it will take any action permitted to be taken by a holder of New Notes, including the presentation of New Notes for exchange as described below, only at the direction of one or more participants to whose accounts the DTC interests in the Global Note are credited and only in respect of that portion of the aggregate principal amount of New Notes as to which that participant or those participants has or have given that direction. However, if there is an Event of

Default under the Indenture applicable to the Global Note, DTC will exchange the Global Note for Certificated Securities, which it will distribute to its participants.

Although DTC has agreed to the foregoing procedures in order to facilitate transfers of interests in the Global Note among participants of DTC, it is under no obligation to perform those procedures and those procedures may be discontinued at any time. Neither TransDigm nor the Trustee will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

CERTIFICATED SECURITIES

Certificated securities shall be issued in exchange for the Old Notes in the Exchange Offer or for beneficial interest in the Global Note, in each case, if requested by a Holder of such Old Note or such beneficial interests, respectively. In addition, certificated securities shall be issued in exchange for beneficial interests in the Global Note if DTC is at any time unwilling or unable to continue as a depositary for the Global Note and a successor depositary is not appointed by TransDigm within 90 days.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following general discussion summarizes the material U.S. federal income tax aspects of the exchange offer to holders of the Old Notes. This discussion is summary for general information only and does not consider all aspects of the Old Notes in light of such holder's personal circumstances. This discussion also does not address the U.S. federal income tax consequences to holders subject to special treatment under the U.S. federal income tax laws, such as dealers in securities, or foreign currency, tax-exempt entities, banks, thrifts, insurance companies, persons that hold the Old Notes as part of a "straddle", a "hedge" against currency risk or a "conversion transaction"; persons that have a "functional currency" other than the U.S. dollar, and investors in pass-through entities. In addition, this discussion does not prescribe any tax consequences arising out of the tax laws of any state, local or foreign jurisdiction.

This discussion is based upon the Code, existing and presupposed regulations thereunder, Internal Revenue Service ("IRS") rulings and pronouncements and judicial decision now in effect, all of which are subject to change, possibly on a retroactive basis. TransDigm has not and will not seek any rulings or opinions from the IRS or counsel with respect to the matters discussed below. There can be no assurance that the IRS will not take positions concerning the tax consequences of the exchange offer which are difference from those discussed herein.

HOLDERS OF THE OLD NOTES SHOULD CONSULT THEIR OWN ADVISORS CONCERNING THE APPLICATION OF U.S. FEDERAL INCOME TAX LAWS, AS WELL AS THE LAWS OF ANY STATE, LOCAL OR FOREIGN JURISDICTION, TO THE EXCHANGE OFFER IN LIGHT OF THEIR PARTICULAR SITUATIONS.

The exchange of Old Notes for New Notes under the terms of the exchange offer should not constitute a taxable exchange. As a result, a holder (A) should not recognize taxable gains of loss as a result of exchanging Old Notes for New Notes under the terms of the exchange offer, (B) the holding period of the New Notes should include the holding period of the Old Notes exchanged for the New Notes and (C) the adjusted tax basis of the New Notes should be the same as the adjusted tax basis, immediately before the exchange of the Old Notes exchange for the New Notes.

115

PLAN OF DISTRIBUTION

Each broker-dealer that receives New Notes for its own account in the exchange offer must acknowledge that it will deliver a prospectus together with any resale of those New Notes. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in the resales of New Notes received in exchange for Old Notes where those Old Notes were acquired as a result of market-making activities or other trading activities. TransDigm has agreed that for a period of up to 180 days after the Expiration Date, it will make this Prospectus, as amended or supplemented, available to any broker-dealer that requests it in the letter of transmittal for use in any such resale.

TransDigm and the Guarantors will not receive any proceeds from any sale of New Notes by broker-dealers or any other persons. New Notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the New Notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such New Notes. Any broker-dealer that resells New Notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of those New Notes may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any such resale of New Notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

TransDigm has agreed to pay all expenses incident to TransDigm's performance of, or compliance with, the Registration Rights Agreement and will indemnify the holders of Old Notes including any broker-dealers, and certain parties related to such holders, against certain types of liabilities, including liabilities under the Securities Act.

INDEPENDENT AUDITORS' REPORT

To the Shareholders and Board of Directors of TransDigm Holding Company

We have audited the accompanying consolidated balance sheets of TransDigm Holding Company and its subsidiaries (the "Company") as of September 30, 1998 and 1997, and the related consolidated statements of income and retained earnings (deficit) and of cash flows for each of the three years in the period ended September 30, 1998. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of TransDigm Holding Company and its subsidiaries as of September 30, 1998 and 1997, and the results of their operations and their cash flows for each of the three years in the period ended September 30, 1998 in conformity with generally accepted accounting principles.

As discussed in Note 17 to the consolidated financial statements, in 1998, the Company retroactively changed its method of accounting for put warrants.

TRANSDIGM HOLDING COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

YEARS ENDED SEPTEMBER 30, 1998, 1997 AND 1996

1. DESCRIPTION OF THE BUSINESS AND MERGER

TransDigm Holding Company ("Holding") through its wholly-owned operating subsidiary, TransDigm Inc. ("TransDigm"), is a premier supplier of proprietary mechanical components servicing the aircraft, mining, marine and other manufacturing industries. TransDigm along with its wholly-owned subsidiary, Marathon Power Technologies Company ("Marathon"), offers a broad line of component products including tube connectors, valves, batteries, static inverters, pumps, quick disconnects, clamps and ball bearing and sliding controls. Holding has no operations, liabilities or assets except for its investment in TransDigm.

On August 3, 1998, Phase II Acquisition Corp. ("Acquiror"), an entity formed by affiliates of Odyssey Investment Partners, LP ("Odyssey") and Holding entered into a definitive agreement and plan of merger which agreement was amended on November 9, 1998 (the "Merger Agreement" or the "Merger"). Pursuant to the terms of the Merger, Acquiror will be merged with and into Holding, with Holding being the surviving corporation in the Merger (the "Surviving Corporation"). In the Merger, holders of Holding's outstanding common stock will be entitled to receive, in exchange for each outstanding share of common stock (except for shares held directly or indirectly by Holding or the Rolled Shares, as defined below) the "Per Share Merger Consideration" as defined in the Merger Agreement. The aggregate consideration payable pursuant to the Merger, including amounts payable to holders of options and warrants, is expected to be approximately $299.7 million.

In connection with the Merger, Kelso Investment Associates IV, LP and Kelso Equity Partners II, LP (collectively "Kelso") will retain approximately 15.4% of the Surviving Corporation's outstanding common stock (the "Rolled Shares") subject to adjustment for certain transactions prior to closing. In addition, certain members of management of Holding agreed, in connection with and as a condition to entering into the Merger Agreement, to rollover stock options with an estimated gross and net value of approximately $17.2 million and $13.7 million, respectively.

The Merger is intended to be treated as a recapitalization for financial reporting purposes which will have no impact on the historical basis of Holding's consolidated assets and liabilities. The Merger is subject to customary closing conditions, including the termination or expiration of the relevant waiting period under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended, Holding having a minimum consolidated net worth, as defined, at closing of not less than $52 million and funding of committed financing. Odyssey has received financing commitments for the transactions from Bankers Trust Corporation, whose commitments are subject to certain conditions.

Simultaneously with the Merger, Holding and TransDigm will refinance all of its existing debt (Note 9). The Merger, the refinancing, and payment of fees and expenses are expected to be funded by (i) existing cash balances, (ii) investments by Odyssey of $100.2 million, (iii) funds from a new $120 million Senior Credit Facility, (iv) funds from $125 million senior subordinated notes and (v) Holding PIK notes and additional common stock of $20 million issued to certain stockholders. After consummation of the Merger, Holding anticipates that it will have approximately $27.0 million available for working capital, certain permitted acquisitions and for general corporate purposes under the new Senior Credit Facility.

Upon consummation of the Merger, Odyssey and its co-investors will own approximately 73.7% of the Surviving Corporation's common stock and Kelso and other continuing stockholders will own approximately 26.3% of the outstanding shares of Holdings' common stock on a fully diluted basis.

TRANSDIGM HOLDING COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

YEARS ENDED SEPTEMBER 30, 1998, 1997 AND 1996

1. DESCRIPTION OF THE BUSINESS AND MERGER (CONTINUED) During each of the years ended September 30, 1998, 1997 and 1996, TransDigm paid Kelso a management fee of approximately $0.1 million.

2. ACQUISITION

On August 8, 1997, TransDigm acquired all of the outstanding common stock of Marathon for approximately $41.6 million in cash (including acquisition expenses), $4 million of which was placed into two $2 million escrow accounts (an environmental escrow and an indemnity escrow) to indemnify TransDigm in the event certain defined environmental and other costs were incurred by Marathon or TransDigm subsequent to the acquisition. At September 30, 1997, a post-closing purchase price adjustment of approximately $.8 million was due from the seller (see Note 4), which was received during November 1997 from the indemnity escrow. The remainder of the indemnity escrow was released to the seller during the year ended September 30, 1998. The environmental escrow account expires after the occurrence of certain defined events in the Stock Purchase Agreement. During September 1998, the seller filed a lawsuit against the Company to release the environmental escrow alleging that the Company had violated the requirements of the Stock Purchase Agreement relating to the investigation of the presence of certain contaminants at the Marathon facility in Texas (Note 15). The Company has filed counter claims against the seller and the ultimate outcome of this matter cannot presently be determined.

The acquisition has been accounted for as a purchase. Accordingly, the purchase price has been allocated to the assets acquired and liabilities assumed based upon their estimated fair value at the date of acquisition, as follows:

Current assets.....................................................  $   8,176
Property and equipment.............................................      9,519
Intangible and other assets........................................     28,859
Current liabilities................................................     (4,308)
Other liabilities..................................................     (1,389)
                                                                     ---------
    Net............................................................  $  40,857
                                                                     ---------
                                                                     ---------

The acquisition was financed with available cash of approximately $10.9 million and the proceeds of senior term debt of approximately $30 million. The excess of the aggregate purchase price over the fair market value of net assets acquired of approximately $28.9 million was recognized as goodwill.

The following table summarizes the unaudited consolidated pro forma results of operations, as if the acquisition had occurred at the beginning of the following periods:

                                                                            1997       1996

                                                                               THOUSANDS)

Income before income taxes and extraordinary items......................     11,220      9,190
Net income..............................................................      3,894      1,522

Pro forma net income for the year ended September 30, 1997 includes an extraordinary loss from extinguishment of debt (net of income taxes of $975) of $1,462. Pro forma net income for the year ended September 30, 1996 includes an extraordinary gain from Marathon's extinguishment of debt (net of income taxes of $135) of $230.

This pro forma information does not purport to be indicative of the results that actually would have been obtained if the operations had been combined during the periods presented and is not intended to be a projection of future results.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CONSOLIDATION--The accompanying consolidated financial statements include the accounts of TransDigm Holding Company and subsidiaries (collectively the "Company"). All significant intercompany balances and transactions have been eliminated. Because TransDigm Holding Company has no operations of its own and, prior to the Recapitalization, had no assets or liabilities other than its equity interest in TransDigm, the consolidated financial statements of TransDigm Holding Company for the three year period ended September 30, 1998 are identical to the historical consolidated financial statements of TransDigm.

REVENUE RECOGNITION--Revenue is recognized when products are shipped to the customer. Any anticipated losses on contracts are charged to earnings when identified.

CASH EQUIVALENTS--The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

ALLOWANCE FOR UNCOLLECTIBLE ACCOUNTS--The Company reserves for amounts determined to be uncollectible based on specific identification and historical experience.

INVENTORIES--Inventories are stated at the lower of cost or market. Cost of inventories is determined by the average cost and the first-in, first-out (FIFO) methods. In accordance with industry practice, all inventories are classified as current assets even though a portion of the inventories is not expected to be realized within one year.

PROPERTY, PLANT AND EQUIPMENT--Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method at rates based on the estimated useful lives of the assets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

YEARS ENDED SEPTEMBER 30, 1998, 1997 AND 1996

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) DEBT ISSUE COSTS AND DISCOUNTS--The cost of obtaining financing for the acquisition as well as debt discounts are amortized using the interest method over the respective terms of the related debt issues.

INTANGIBLE ASSETS--Intangible assets are amortized on a straight-line basis over their respective estimated useful lives ranging from 2 to 40 years. The Company assesses the recoverability of intangibles by determining whether the amortization over the remaining life can be recovered through projected undiscounted cash flows from future operations.

INCOME TAXES--The Company accounts for income taxes using an asset and liability approach. Deferred taxes are recorded for the difference between the book and tax basis of various assets and liabilities.

PRODUCT WARRANTY COSTS--The Company provides a one year warranty on certain products beginning on the date the product is installed on an aircraft. A provision for estimated sales returns and the cost of repairs is recorded at the time of sale and periodically adjusted to reflect actual experience.

ESTIMATES--The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

4. ACCOUNTS RECEIVABLE, MAJOR CUSTOMERS AND EXPORT SALES

                                                                          ---------  ---------

REVOLVING CREDIT, SWING LINE, AND TERM LOANS--During the year ended September 30, 1997, the Company obtained a new $70 million credit facility with a group of financial institutions which consist of a $20 million revolving credit line (including $1 million of available swing line loans) and $50 million of term loans. At September 30, 1998, the Company had $20 million of borrowings (the entire revolving credit line) available under the credit facility. Any amounts borrowed under the revolving credit and swing line loans mature in the year 2003 and amounts borrowed under the term loans mature on various dates through the year 2003.

Borrowings under the credit facility bear interest at the Company's option of (1) the Alternate Base Rate plus .25% or (2) the LIBO rate for Eurodollar loans plus 1.25%, payable quarterly. The Alternate Base Rate is equal to the highest of (a) the Prime Rate, (b) the Base CD Rate plus 1% or (c) the Federal Funds Effective Rate plus .5%. The interest rate on outstanding borrowings at September 30, 1998 was approximately 6.9%.

Any amounts borrowed under the credit facility are collateralized by substantially all of the tangible assets of the Company. The agreement also contains a number of restrictive covenants that, among other things, limit the ability of the Company to incur indebtedness, pay dividends, engage in mergers and consolidations, engage in transactions with affiliates, make capital expenditures, engage in sales of assets or the stock of a subsidiary company and make certain investments. The agreement also requires the maintenance of a minimum net worth as well as debt to adjusted earnings, interest coverage, and other ratios. The Company is in compliance with all financial covenants of the credit facility as of September 30, 1998.

9. DEBT (CONTINUED) The maturities of the Company's term loans are as follows: 1999--$5 million; 2000 through 2003-- $10 million each year.

SUBORDINATED NOTES--During the year ended September 30, 1997, the Company redeemed, in advance of their scheduled maturity, outstanding subordinated notes which had a carrying value at the time of the redemption of approximately $19.3 million ($20 million principal balance net of an unamortized discount of approximately $.7 million). As a result of the redemption, the Company recognized an extraordinary loss of approximately $1.5 million (net of a current income tax benefit of approximately $1 million) on the early extinguishment of debt which included prepayment costs of approximately $.8 million and the write-off of the remaining unamortized debt issue costs of approximately $1 million. The subordinated notes bore interest at an annual rate of 13%, payable semi-annually.

The subordinated notes included detachable warrants to purchase approximately 16,000 shares of non-voting common stock of TransDigm Holding Company at a price of $.10 per share which were not affected by the redemption of the subordinated notes. The warrants are not exercisable except in connection with the following triggering events: public offering of TransDigm Holding Company's common stock, a business combination in which the Company is not the surviving entity, and a change of control (see Note 1). If no transaction constituting a triggering event is consummated prior to July 31, 1999, warrant holders have the right to exercise a put option requiring the Company to repurchase all of the warrants at their then appraised fair market value. If the warrant holders have not exercised their put option prior to September 30, 2001, then TransDigm Holding Company will have the right to call the warrants at their then appraised fair market value.

10. RETIREMENT PLANS

The Company has two non-contributory, defined benefit pension plans which together cover all of its union employees. The plans provide benefits of stated amounts for each year of service. The Company's funding policy is to contribute actuarially determined amounts allowable under Internal Revenue Service regulations. The plans' assets consist primarily of guaranteed investment contracts with an insurance company.

Net periodic pension cost of the defined benefit plans consists of the following for the years ended September 30 (dollars in thousands):

                                                                        1998       1997       1996

The assumptions used to determine net periodic pension cost as well as the funded status are:

                                                                                     1998         1997
                                                                                     -----        -----
Discount rate...................................................................         6.5%         7.5%
Long-term rate of return on plan assets.........................................         7.5%         7.5%

The provisions of Financial Accounting Standards Board Statement No. 87, "Employers' Accounting for Pensions" require recognition in the balance sheet of an additional minimum liability and related intangible asset (limited by the amount of unamortized prior service cost) for pension plans with accumulated benefits in excess of plan assets. At September 30, 1998 and 1997, an additional liability of $1.4 million and $.9 million, respectively, is reflected in the consolidated balance sheets. At September 30, 1998 and 1997, the liability exceeded the unrecognized prior service cost resulting in a charge to stockholders' equity, net of taxes, of $.8 million and $.5 million, respectively.

The Company also sponsors a defined contribution employee savings plan which covers substantially all of the Company's non-union employees. Under the plan, the Company contributes a percentage of employee compensation and matches a portion of employee contributions to the plan. The cost recognized for such contributions under this plan for the years ended September 30, 1998, 1997 and 1996 was approximately $.6 million in all years.

The Company applies Accounting Principles Board Opinion No. 25 and related interpretations in accounting for its stock option plans. No compensation cost has been recognized for its stock option plans. Had compensation cost for the Company's stock option plans been determined based on the fair value at the grant dates for awards under those plans consistent with the method specified in Statement of Financial Accounting Standards No. 123, the Company's net income for the years ended September 30, 1998 and 1997 would have been reduced by approximately $115,000 in both years.

The weighted average fair value of options granted during fiscal 1997 and 1996 was $950,000 and $340,000, respectively. The fair value of the options granted was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions for grants in both fiscal 1997 and 1996: risk-free interest rates ranging from 6.25% to 6.85%, expected life of seven years, expected volatility and dividend yield of 0%.

13. LEASES

TransDigm leases office space for its corporate headquarters and one of its divisions. The lease requires rental payments of approximately $200,000 per year through the initial term of the lease, which expires in 1999. TransDigm may also be required to share in the operating costs of the facility under certain conditions. TransDigm has the option to renew the lease for an additional five years beyond the expiration of the initial lease term. TransDigm also has commitments under operating leases for vehicles and equipment. Rental expense was $599,000 in 1998, $540,000 in 1997, and $570,000 in 1996. Future, minimum rental commitments at September 30, 1998 under operating leases having initial or remaining non-cancelable lease terms exceeding one year are $383,000 in 1999, $166,000 in 2000, $79,000 in 2001, and $29,000 in 2002.

14. FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying value of the Company's cash and cash equivalents, accounts receivable and payable, and accrued liabilities approximate their fair value due to the short-term maturities of these assets and liabilities. The Company also believes that the aggregate fair value of its term loans approximates its carrying amount because the interest rates on the debt are reset on a frequent basis to reflect current market rates.

15. CONTINGENCIES

ENVIRONMENTAL--The soil and groundwater beneath the Company's facility in Waco, Texas have been impacted by releases of hazardous materials. The resulting contaminants of concern have been delineated and characterized. Because the majority of these contaminants are presently below action levels prescribed by the Texas Natural Resources Conservation Commission ("TNRCC"), and because an escrow (Note 2) was previously funded to cover the cost of remediation that TNRCC might require for those contaminants currently in excess of action limits, management does not believe the condition of the soil and groundwater at the Waco facility will require incurrence of material expenditures.

OTHER--While the Company is currently involved in certain legal proceedings, management believes the results of these proceedings will not have a material effect on the financial condition, results of operations or cash flows of the Company. During the ordinary course of business, the Company is from time to time threatened with, or may become a party to, legal actions and other proceedings. The Company believes that its potential exposure to such legal actions is adequately covered by its aviation product and general liability insurance.

16. NEW ACCOUNTING STANDARDS

In June 1997, the Financial Accounting Standards Board issued SFAS No. 130, "Reporting Comprehensive Income." The statement requires that an enterprise classify items of other comprehensive income by their nature in a financial statement and display the accumulated balance of other comprehensive income separately from retained earnings and additional paid-in capital in the equity section of a statement of financial position. The Company's other comprehensive income consists of the minimum pension liability adjustment. If the Company had adopted SFAS No. 130, comprehensive income would have been reduced by $252,000, $122,000, and $177,000 in 1998, 1997, and 1996, respectively. The Company will adopt this standard during fiscal 1999.

In June 1997, the Financial Accounting Standards Board issued SFAS No. 131, "Disclosures About Segments of an Enterprise and Related Information." The statement requires that a public business enterprise report financial and descriptive information about its reportable operating segments such as a measure of segment profit or loss, certain specific revenue and expense items, and segment assets. The Company will adopt this standard during fiscal 1999.

In February 1998, the Financial Accounting Standards Board issued SFAS No. 132, "Employer's Disclosures about Pensions and Other Postretirement Benefits." The statement requires an enterprise to disclose certain information about its pension and postretirement benefits, including a reconciliation of beginning and ending balances of the benefit obligation, the funded status of the plans, and the amount of net periodic benefit cost recognized. The Company will adopt this standard during fiscal 1999.

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." This statement establishes accounting and reporting standards for derivative instruments embedded in other contracts (collectively referred to as derivatives), and for hedging activities. It requires that an entity recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value. If certain conditions are met, a derivative may be specifically designated as (a) a hedge of the exposure to changes in the fair value of a recognized asset or liability or an unrecognized firm commitment, (b) a

16. NEW ACCOUNTING STANDARDS (CONTINUED) hedge of the exposure to variable cash flows of a forecasted transaction, or (c) a hedge of the foreign currency exposure of a net investment in a foreign operation, an unrecognized firm commitment, an available-for-sale security, or a foreign-currency-denominated forecasted transaction. The Company will adopt this standard during fiscal 2000.

While management has not completed its analysis of these new accounting standards, the adoption of these standards is not expected to have a material effect on the Company's financial statements.

17. ACCOUNTING CHANGE

In connection with the planned registration of the Senior Subordinated Notes described in Note 1 with the Securities and Exchange Commission ("Commission"), the Company has retroactively adopted a new method of accounting for the put warrants issued in 1993 (see Note 9). The Company adopted the new method to comply with the requirements of the Commission for put warrants. Under the new method of accounting, the Company has recorded a liability for the estimated put value of the warrants and is recognizing changes in the estimated put value in earnings. Previously, the Company recognized the warrants as a component of stockholders' equity and adjusted the carrying value of the warrants on a straight-line basis for the difference between their original recorded amount of $1.6 million and their estimated put value in July 1999, with an offsetting charge to the Company's retained earnings (deficit). The Company has restated its 1997 and 1996 consolidated financial statements for this change in accordance with the provisions of Accounting Principles Board Opinion No. 20, "Accounting Changes." The significant effects of the change in accounting on the Company's consolidated statements of income and retained earnings (deficit) are as follows (dollars in thousands):

                                                                               1997       1996
                                                                             ---------  ---------
As previously reported:
  Income before extraordinary loss.........................................  $   9,434  $   3,335
  Net income...............................................................      7,972      3,335
As restated:
  Income before extraordinary loss.........................................      4,634      1,175
  Net income...............................................................      3,172      1,175

Because the Merger described in Note 1 constitutes a "triggering event" pursuant to the terms of the warrants, the warrant holders will be permitted to exercise their put option in connection with the closing of the transaction. Accordingly, the Company has adjusted the carrying value of the warrants in the accompanying September 30, 1998 consolidated balance sheet to their estimated fair value.

18. SUBSEQUENT EVENT

The Merger described in Note 1 was completed on December 3, 1998.

TRANSDIGM HOLDING COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

THIRTEEN WEEKS ENDED JANUARY 1, 1999 AND DECEMBER 26, 1997

1. DESCRIPTION OF THE BUSINESS AND MERGER

TransDigm Holdings Company ("Holdings") through its wholly owned operating subsidiary, TransDigm Inc. ("TransDigm"), is a premier supplier of proprietary mechanical components servicing the aircraft, mining, marine and other manufacturing industries. TransDigm along with its wholly-owned subsidiary, Marathon Power Technologies Company ("Marathon"), offers a broad line of component products including tube connectors, valves, batteries, static inverters, pumps, quick disconnects, clamps and ball bearings and sliding controls.

On December 3, 1998, Phase II Acquisition Corp. ("Acquiror"), an entity formed by affiliates of Odyssey Investment Partners, LP ("Odyssey") and Holdings consummated a definitive agreement and plan of merger (the "Merger Agreement" or the "Merger"). Pursuant to the terms of the Merger, Acquiror was merged with and into Holdings, with Holdings being the surviving corporation in the Merger (the "Surviving Corporation"). In the Merger, owners of Holdings' outstanding common stock received, in exchange for each outstanding share of common stock (except for shares held directly or indirectly by Holdings or the Rolled Shares, as defined below), the "Per Share Merger Consideration" as defined in the Merger Agreement. The aggregate consideration payable pursuant to the Merger, including amounts payable to holders of options and warrants, was approximately $299.7 million.

In connection with the Merger, Kelso Investment Associates IV, LP and Kelso Equity Partners II, LP (collectively "Kelso") retained approximately 15.4% of the Surviving Corporation's outstanding common stock (the "Rolled Shares"). In addition, certain members of management of Holdings agreed, in connection with and as a condition to entering into the Merger Agreement, to rollover stock options with an estimated gross and net value of approximately $17.2 million and $13.7 million, respectively. The Merger was treated as a recapitalization (the "Recapitalization") for financial reporting purposes, which had no impact on the historical basis of Holdings' consolidated assets and liabilities.

Simultaneously with the Merger, Holdings and TransDigm (collectively with Marathon, the "Company") refinanced all of its existing debt. The Merger, the refinancing, and payment of fees and expenses were funded by (i) existing cash balances, (ii) investments by Odyssey of $100.2 million, (iii) funds from a new $120 million Senior Credit Facility, (iv) funds from $125 million Senior Subordinated Notes and (v) Holdings PIK Notes of $20 million issued to certain stockholders. At January 1, 1999, Holdings had $29.0 million available for working capital, certain permitted acquisitions and general corporate purposes under the new Senior Credit Facility.

Separate financial statements of TransDigm are not presented since the Senior Subordinated Notes are guaranteed by Holdings and all direct and indirect subsidiaries of TransDigm, and since Holdings has no operations or assets separate from its investment in TransDigm.

2. UNAUDITED FINANCIAL INFORMATION

The financial information included herein is unaudited; however, the information reflects all adjustments (consisting solely of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company's financial position and results of operations and cash flows for the interim periods presented. The results of operations for the thirteen weeks ended January 1, 1999 are not necessarily indicative of the results to be expected for the full year.

4. INCOME TAXES

Income tax expense (benefit) as a percentage of income (loss) before income taxes was (23.3)% for the first quarter of fiscal 1999 compared to 38.6% for the first quarter of fiscal 1998. The tax benefit recorded for the first quarter of fiscal 1999 was significantly impacted by the non-deductible expenses incurred in connection with the Recapitalization.

5. REDEEMABLE COMMON STOCK

The redeemable common stock represents the estimated value of common stock held by management shareholders which have certain put rights.

6. CONTINGENCIES

ENVIRONMENTAL--The soil and goundwater beneath the Company's facility in Waco, Texas have been impacted by releases of hazardous materials. The resulting contaminants of concern have been delineated and characterized. Because the majority of these contaminants are presently below action levels prescribed by the Texas Natural Resources Conservation Commission ("TNRCC"), and because an escrow was previously funded to cover the cost of remediation that TNRCC might require for those contaminants currently in excess of action limits, management does not believe the condition of the soil and groundwater at the Waco facility will require incurrence of material expenditures.

OTHER--While the Company is currently involved in certain legal proceedings, management believes the results of these proceedings will not have a material effect on the financial condition, results of operations or cash flows of the Company. During the ordinary course of business, the Company is from time to time threatened with, or may become a party to, legal actions and other proceedings. The Company believes that its potential exposure to such legal actions is adequately covered by its aviation product and general liability insurance.

MARATHON POWER TECHNOLOGIES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS AND FORMATION

Marathon Power Technologies Company ("Company") was organized in March 1994 and purchased substantially all of the net assets of Marathon Power Technologies, a wholly-owned subsidiary of American Premier Underwriters, Inc., on May 19, 1994. The Company, located in Waco, Texas, manufactures vented and sealed nickel cadmium rechargeable batteries which are used in aviation and consumer electrical equipment. The Company also manufactures static inverters, used largely in the aviation industry, which convert DC power into AC power, as well as other items, such as battery chargers. The Company maintains a subsidiary in the United Kingdom used primarily for distribution of vented products.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company's significant accounting policies are as follows:

PRINCIPLES OF CONSOLIDATION--The financial statements include the accounts of the Company and its wholly-owned subsidiary after elimination of intercompany transactions and balances. Certain reclassifications were made to conform prior year amounts to the current year presentation.

USE OF ESTIMATES--Financial statements prepared in conformity with generally accepted accounting principles require management to make estimates and assumptions about reported amounts of assets and liabilities; disclosure of contingent assets and liabilities and reported amounts of revenues and expenses. Management must also make estimates and judgments about future results of operations related to specific elements of the business in assessing recoverability of assets and recorded values of liabilities. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS--Cash and cash equivalents include cash on hand and short-term investments with original maturities of three months or less.

CREDIT CONCENTRATIONS--The Company sells products chiefly to aviation companies and/or suppliers to aviation companies, generally on an unsecured basis. The Company provides estimated reserves against accounts receivable for collection losses.

INVENTORIES--Inventories are stated at the lower of cost or market, cost being determined on a first-in first-out basis.

PROPERTY PLANT AND EQUIPMENT--Property, plant and equipment, including assets under capital lease, are carried at acquisition cost. Depreciation and amortization are computed on the straight-line basis over the estimated remaining useful lives of the assets (ranging from 2 to 30 years) and the remaining term of capital leases, respectively. Repair and maintenance expenditures are charged to operations as incurred, and expenditures for major renewals and betterments are capitalized. When units of property are disposed, the cost and related accumulated depreciation are removed from the accounts, and the resulting gains or losses are included in operations.

REVENUE RECOGNITION--Sales revenue and related cost of sales are recognized as products are shipped to customers. In the normal course of business, the Company provides for product defects through the issuance of one to two year warranties covering its products. The costs associated with these warranties are accrued at the time of sale which totaled $130,000 and $232,000 in 1996 and 1995, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) INCOME TAXES--Deferred income taxes are provided for differences between tax laws and financial accounting standards regarding the recognition and measurement of assets, liabilities, revenues and expenses. Such differences result principally from different methods of purchase price allocation for tax and financial accounting purposes and depreciation.

FAIR VALUE OF FINANCIAL INSTRUMENTS--Management believes the recorded values of financial instruments approximate their current fair values as such items are current in nature and/or generally bear variable interest rates which adjust yield to derive current market value.

STOCK-BASED COMPENSATION--In October 1995, Statement of Financial Accounting Standards No. 123, "Accounting for Stock-based Compensation" ("SFAS 123") was issued. This statement requires the fair value of stock options and other stock-based compensation issued to employees to either be included as compensation in the statement of operations, or the pro forma effect on net income of such compensation expense to be disclosed in the footnotes to the Company's financial statements commencing with the Company's year ending December 31, 1996. The Company has adopted SFAS 123 on a disclosure basis only. As such, implementation of SFAS 123 is not expected to impact the Company's consolidated balance sheet or consolidated statement of operations.

6. LONG-TERM DEBT (CONTINUED) In 1996, the Company extinguished its $2,500,000 subordinated note payable for a cash payment of $2,125,000, obtained from a combination of operating cash flows and an increase in borrowings under the line of credit. The difference between the carrying amount of the note and the cash paid to the holder of such borrowings (and related expenses of $10,000) was recorded as an extraordinary gain on the early extinguishment of debt of $365,000 ($230,000 net of income taxes). The effective tax rate for the extraordinary gain was 37.0%.

10. RELATED PARTY TRANSACTIONS

The Company paid management fees of $200,000 and $181,000 during 1996 and 1995, respectively, which are included in general and administrative expenses, to its principal shareholder under an agreement which calls for quarterly installments equal to 1.0% of quarterly net sales. Included in accrued liabilities other (Note 5) are management fees payable of $51,000 and $46,000 as of December 31, 1996 and 1995, respectively.

Included in treasury stock at December 31, 1996 and 1995 are 75 shares of the Company's common stock which were repurchased from a former employee during 1995 for approximately $8,000.

11. STOCK OPTIONS

The Company established an incentive stock option plan in 1994 under which options to acquire an aggregate of 3,000 shares of the Company's common stock may be granted to employees and consultants of the Company. The plan requires that the exercise price for each stock option be not less than 100% of the fair market value of common stock at the time the option is granted. Both nonqualified stock options and incentive stock options, as defined by the Internal Revenue Code of 1986, as amended, may be granted under the plan. The options are nontransferable and are cancelable if the optionee's employment or other association with the Company is terminated for any reason. The plan and all underlying options terminate on January 1, 2005 or earlier. As of December 31, 1996 and 1995, options of 2,681 and 2,531, respectively, had been granted under the plan.

                                                                           NUMBER OF    EXERCISE

As of December 31, 1996 and 1995, options for 1,609 and 1,012 shares, respectively, were exercisable under the Company's stock option plan.

The fair market values of options as of their grant dates were approximately $49 and $42 per option in December 1996 and 1995, respectively, based on comparison of the fair market value of the underlying shares and the net present value of the exercise price over the period of exercisability at a risk free market rate of 7.9% and 5.7%, respectively. No dividend payments or volatility in stock prices were assumed in the fair market value calculations.

No compensation expense was recorded during 1996 or 1995 for options issued under the plan since the Company accounts for such transactions in accordance with APB Opinion No. 25, "Accounting for Stock Issued to Employees." Had the Company included the stock-based compensation in the consolidated statement of operations, $17,000 and $28,000 in additional employee compensation expenses, net of the effect of income taxes, would have been recorded in 1996 and 1995, respectively. This would result in pro forma net income of $2,413,000 and $1,378,000, respectively.

Under the terms of the May 19, 1994 asset purchase agreement, the Company is indemnified for any preacquisition legal costs. The Company accrues for claims that are both probable and for which expected loss can be reasonably estimated.

ZMP, INC. AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEAR ENDED JUNE 26, 1998

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND NATURE OF BUSINESS--ZMP, Inc. (the "Company" or "ZMP"), through its wholly-owned subsidiary, Adams Rite Aerospace (ARA), designs and manufactures specialized parts and systems for the aerospace industry. The Company operates only in this industry segment and does not have significant foreign operations.

Effective June 29, 1996, the Company adopted a plan to recapitalize the Company and restructure the senior subordinated notes payable. Under this plan, the Company exchanged 9,308 shares of common stock for all of the previously outstanding Series AA, Series A and Series B preferred stock. The Company also issued 90,692 shares of common stock as payment of $9,766,000 of senior subordinated notes payable and accrued interest to the majority stockholder. Additionally, the terms of the remaining senior subordinated notes payable were amended to accrue interest at 12%, payable semiannually on December 31 and June 30, with the principal due on December 31, 1998. On June 8, 1998, ZMP signed an agreement to extend the maturity date of the senior subordinated notes payable to December 31, 1999. The Company accounted for the recapitalization as a deficit reclassification quasi-reorganization and eliminated the prior accumulated deficit against additional paid-in capital. The fair value of the Company's net assets exceeded the book value and, therefore, no adjustment to carrying values was recorded.

On February 23, 1998, the Company relocated its primary operating facility from Glendale, California to a 100,000-square-foot facility located in Fullerton, California.

CONSOLIDATION POLICY--The accompanying consolidated financial statements include the accounts of ZMP and ARA. All significant intercompany accounts and transactions have been eliminated in consolidation.

REPORTING PERIOD--The Company's fiscal year is the 52 or 53 week period ending on the Friday nearest June 30. Fiscal 1998 contained 52 weeks.

REVENUE RECOGNITION, CONCENTRATION OF CREDIT RISK AND EXPORT SALES--The Company recognizes revenue from product sales upon shipment. Substantially all of the Company's accounts receivable are due from companies in the aerospace industry located throughout the United States and internationally. The Company performs periodic credit evaluations of its customers' financial condition and generally does not require collateral. Receivables are generally due within 30 days; however, some European customers have payment terms ranging from 60 to 90 days. Export sales to customers, primarily in western Europe, were $6.5 million for the year ended June 26, 1998.

CASH AND CASH EQUIVALENTS--The Company considers all highly liquid financial instruments with an original maturity of three months or less to be cash equivalents.

EQUIPMENT AND IMPROVEMENTS--Equipment and improvements are stated at cost. Depreciation of equipment is provided for using the straight-line and accelerated methods over the estimated useful lives of the equipment, which range from three to ten years. Amortization of leasehold improvements is provided for using the straight-line method over the shorter of the lease term or the useful life of the improvement.

IMPAIRMENT--The Company reviews the recoverability of long-term and intangible assets to determine if there has been any impairment. This assessment is performed based on the estimated undiscounted future cash flows from operating activities compared with the carrying value of the related assets. If the future cash flows (undiscounted and without interest charges) were less than the carrying value, a writedown would be recorded to reduce the related asset to its estimated fair value.

MAJOR CUSTOMERS--During fiscal 1998, the Company had sales to one customer representing 20% of net sales. Accounts receivable from such customer represent 14% of total receivables at June 26, 1998.

INCOME TAXES--Deferred income taxes represent the tax consequences of differences between the income tax bases of assets and liabilities and their bases for financial reporting purposes. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred income tax assets will not be realized.

USE OF ESTIMATES--The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

LITIGATION--The Company does not anticipate that adverse outcomes in currently pending litigation would have a material adverse effect on its business, results of operations or financial condition.

remaining portion of the warrant vests over three years, with immediate vesting of all warrants upon a change of control, as defined.

8. RETIREMENT AND DEFERRED COMPENSATION PLANS

The Company sponsors a defined contribution retirement plan that covers substantially all of its employees. Contributions to the plan are at the discretion of management and may be discontinued at any time. There are no other postretirement benefits. Included in the consolidated statement of income and retained earnings are expenses for the retirement plan of $127,000 for the year ended June 26, 1998.

The Company also has a deferred compensation agreement with a key employee that provides for payment from a trust upon retirement or other termination of employment. The Company may at any time make additional deposits of cash or other property in trust to the plan.

As of June 26, 1998, the plan assets are invested primarily in mutual funds and are subject to reinvestment as determined by the key employee. Based on the nature of the investments and the ability of the key employee to alter the investment strategy, such plan assets have been classified as trading securities as defined in Statement of Financial Accounting Standards No. 115, ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES. Additionally, the plan assets are classified as noncurrent based on the key employee's intent of maintaining the assets within the plan for a minimum of one year.

On April 23, 1999, TransDigm Inc. acquired ZMP, Inc., including all of its outstanding common stock, for $41 million. The purchase price is subject to adjustment for changes in working capital and other matters as defined in the merger agreement.

grant. Additionally, in December 1998, the Company provided the Executive with a second $214,000 loan evidenced by a demand note, bearing interest at the Internal Revenue Service's permitted minimum interest rate (4.28% at December 25, 1998), and collateralized by the Company's common stock held by the Executive.

Both loans are included in accounts receivable in the accompanying balance sheet.

5. LINE OF CREDIT

In September 1998, ARA renewed a revolving line of credit through July 2000 which provides for maximum borrowings of $2,000,000, limited to 80% of eligible accounts receivable, as defined, and includes a sub-limit feature for the issuance of commercial letters of credit in an amount not to exceed $1,000,000. Borrowings under the revolving credit facility bear interest at the bank's prime rate plus .25% (7.75% at December 25, 1998). The revolving credit facility was not utilized by ARA during the two 26 week periods ended December 25, 1998 and December 26, 1997. The availability of funds under the revolving credit facility terminates upon a change of control of the Company.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the General Corporation Law of the State of Delaware ("DGCL") provides that a corporation has the power to indemnify any director or officer, or former director or officer, who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) against the expenses (including attorney's fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with the defense of any action by reason of being or having been directors or officers, if such person shall have acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, provided that such person had no reasonable cause to believe his conduct was unlawful, except that, if such action shall be in the right of the corporation, no such indemnification shall be provided as to any claim, issue or matter as to which such person shall have been judged to have been liable to the corporation unless and only to the extent that the Court of Chancery of the State of Delaware (the "Court of Chancery"), or any court in such suit or action was brought, shall determine upon application that, despite the liability judgment, but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the Court of Chancery or such other court shall deem proper.

Accordingly, each of (i) the Restated Certificate of Incorporation (dated September 28, 1993) and the amendments thereto (dated December 21, 1993) of TransDigm Holding Company (filed herewith as Exhibits 3.1 and 3.2, respectively), (ii) the Certificate of Incorporation (dated July 2, 1993) and the amendments thereto (dated July 22, 1993) of TransDigm Inc.

(filed herewith as Exhibit 3.10) and (v) the Articles of Incorporation (dated July 30, 1986) and the amendments thereto (dated September 12, 1986, January 27, 1992, December 31, 1992 and August 11, 1997) of Adams Rite Aerospace, Inc. (filed herewith as Exhibits 3.12, 3.13, 3.14, 3.15 and 3.16, respectively), provide that subject to certain exceptions, TransDigm Holding Company, TransDigm Inc., Marathon Power Technologies Company, ZMP, Inc. and Adams Rite Aerospace, Inc. (collectively, the "Co-Registrants" and, individually, the "Co-Registrant") shall indemnify each of its respective director or officer against any and all expenses (including attorneys' fees), judgments, fines, excise taxes assessed with respect to any employee benefit plan, or penalties and amounts paid in settlement actually and reasonably incurred by such director or officer in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including an action by or in the right of such Co-Registrant), to which such director or officer is, was or at any time becomes a party, or is threatened to be made a party, by reason of the fact that such director or officer is, was or at any time becomes a director or officer of such Co-Registrant, or is, or was serving, or at any time serves at the request of such Co-Registrant as a director or officer of another corporation, partnership, joint venture, trust or other enterprise. The Restated Certificate of Incorporation or the Certificate of Incorporation, as applicable, and the amendments thereto also provide that the respective Co-Registrant shall advance expenses (including attorneys' fees) actually and reasonably incurred by its director or officer in defending any proceeding and any judgments, fines or amounts to be paid in settlement thereof. The Restated Certificate of Incorporation or the Certificate of Incorporation, as applicable, and the amendments thereto provide, however, that the foregoing provisions shall not require the respective Co-Registrant to pay any indemnity (i) for which payment is actually made to such director or officer under a valid and collectible insurance policy, except in respect of any excess beyond the amount of payment under such

II-1


insurance; (ii) for which such director or officer is indemnified by the respective Co-Registrant pursuant to applicable law or otherwise than pursuant to the Restated Certificate of Incorporation or the Certificate of Incorporation, as applicable, of the respective Co-Registrant; (iii) for an accounting of profits made from the purchase or sale by such director or officer of securities of the respective Co-Registrant within the meaning of Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto or similar provisions of any state statutory law or common law; (iv) on account of such director's or officer's conduct which is finally adjudged by a court to have been knowingly fraudulent, deliberately dishonest or willful misconduct; or (v) if a final decision by a court having jurisdiction in the matter shall determine that such indemnity is not lawful. Such indemnification shall not be deemed exclusive of any other rights to which a director or officer seeking indemnification may be entitled under any statute, the Bylaws, other provisions of the Restated Certificate of Incorporation or the Certificate of Incorporation, as applicable, of the respective Co-Registrant, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such director's or officer's official capacity and as to action in any other capacity while holding such office.

Furthermore, a director of a Co-Registrant shall not be liable to the respective Co-Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (a) for any breach of the director's duty of loyalty to the respective Co-Registrant or its stockholders,
(b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) for the unlawful payment of a dividend, unlawful stock purchase or unlawful redemption, (d) for any transaction from which the director derived an improper personal benefit, or such exemption from liability or limitation thereof is not permitted under the DGCL as currently in effect or as the same may hereafter be amended.

ITEM 22. UNDERTAKINGS.

Each of the undersigned Co-Registrants hereby undertakes that insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the respective Co-Registrant pursuant to the foregoing provisions described under Item 20 above, or otherwise, the respective Co-Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim of indemnification against such liabilities (other than the payment by the respective Co-Registrant of expenses incurred or paid by a director, officer or controlling person of such Co-Registrant in the successful defense of any action, suit paid by a director, officer or controlling person of such Co-Registrant in the successful defense of any action, suit or proceeding) is asserted against such Co-Registrant by such director, officer or controlling person in connection with the securities being registered, such Co-Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

II-5


Each of the undersigned Co-Registrants hereby undertakes (i) to respond to requests for information that is incorporated by reference into this Prospectus pursuant to Items 4, 10(b), 11, or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This undertaking also includes documents filed subsequent to the effective date of the Registration Statement through the date of responding to the request.

Each of the undersigned Co-Registrants hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the Registration Statement when it became effective.

Each of the undersigned Co-Registrants hereby undertakes to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement (notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement); and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

Each of the undersigned Co-Registrants hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this Registration Statement, by any person or party who is deemed to be an underwriter within the meaning of Rule
145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the application form.

Each of the undersigned Co-Registrants hereby undertakes that every prospectus: (i) that is filed pursuant to the immediately preceding paragraph or
(ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933, as amended, and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Each of the undersigned Co-Registrants hereby undertakes to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the exchange offer.

(b) The Base Equity Price shall be paid or applied as follows:
(i) Buyer shall cause the Surviving Corporation to retain (for ultimate payment to the holders of Dissenting Shares if and to the extent required to be so paid) an amount equal to the Base Equity Price multiplied by a fraction, the numerator of which is the number of Dissenting Shares, and the denominator of which is the number of ZMP Shares plus the number of Dissenting Shares (the "Dissenting Shares Amount"); (ii) Buyer shall deliver to the Escrow Agent (I) an amount equal to the sum of (x) $3,000,000 and (y) if, and only if, there are any Dissenting Shares, an additional $200,000 for deposit in one escrow account (the "Escrow Account") and (II) an amount equal to the sum of $750,000 for deposit in a separate escrow account (the "Glendale Escrow Account"); and (iii) Buyer shall cause the Surviving Corporation to pay to each holder of ZMP Shares or options or warrants to acquire ZMP Shares an amount equal to such holder's Applicable Percentage of the Base Equity Price remaining after the retention and payment described in clauses (i) and (ii) above.

Following the Closing, the Merger Consideration shall be adjusted as provided herein to reflect changes in Net Working Capital as determined based on the Closing Date Statement of Net Working Capital compared to the Target Net Working Capital.

(a) Within 60 days following Closing, Buyer and the Surviving Corporation shall cause to be prepared and delivered to the Shareholders' Representative a statement of the current assets (the "Current Assets") and the current liabilities (the "Current Liabilities") of the Company and ARA as of the close of business on the Friday immediately preceding the Closing (the "Closing Date Statement of Net Working Capital") along with supporting materials and calculations and a calculation of the amount, if any, due to the Selling Shareholders or Buyer as a result of the adjustments set forth in this Section
2.10. The Current Assets and Current Liabilities set forth on the Closing Date Statement of Net Working Capital shall be determined in accordance with GAAP applied in the manner, and according to the principles, applied in the preparation of the Audited Financial Statements as of and for the period ended June 26, 1998; provided, however, that in determining Current Assets and Current Liabilities, the exclusions and adjustments described on Schedule 2.10 shall be given effect. Upon the request of Shareholders' Representative, Buyer and the Company shall take such steps as may be reasonably necessary to permit a representative of the Shareholders' Representative to observe all procedures undertaken in the preparation of the Closing Date Statement of Net Working Capital and to provide the

12

Shareholders' Representative access at all reasonable times to the personnel, properties, books and records of the Company and ARA for the purpose of reviewing and ascertaining the accuracy of the Closing Date Statement of Net Working Capital.

(b) Within 30 days after receipt of the Closing Date Statement of Net Working Capital, the Shareholders' Representative shall, in a written notice to Buyer, either accept the Closing Date Statement of Net Working Capital or describe in reasonable detail, in writing, any proposed adjustments and the reasons therefor. No such written notice shall be delivered to Buyer if the net proposed adjustments in the aggregate amount to an increase in Net Working Capital of less than $25,000. If the Buyer has not received such notice of proposed adjustments within such 30 day period, the Shareholders' Representative will be deemed irrevocably to have accepted the Closing Date Statement of Net Working Capital. In the event that Shareholders' Representative and Buyer are not able to agree on the Net Working Capital within 30 days from and after the receipt by Buyer of any adjustments proposed by the Shareholders' Representative, such dispute shall be submitted to Arthur Andersen LLP for computation or verification in accordance with the provisions of this Agreement. Such firm shall determine as promptly as practicable, but in any event within 30 days of the date on which such dispute is referred to such firm, whether the Closing Date Statement of Net Working Capital was prepared in accordance with the standards set forth in this Agreement on the basis solely of the written submissions of the parties, and whether and to what extent (if any) Net Working Capital as shown thereon requires adjustment. The results of such accounting firm's report shall be binding, conclusive and non-appealable upon Shareholders' Representative, the Selling Shareholders and Buyer, and such accounting firm's fees and expenses shall be borne equally by Buyer, on one hand, and the Selling Shareholders (through a reduction in any amount owed to them under this Section 2.10 or, if no such amount is owed to them, through a payment out of the Escrow Account) on the other. Buyer and the Shareholders' Representative will jointly instruct the Escrow Agent, in writing, to make any such payment.

(c) Upon acceptance of the Closing Date Statement of Net Working Capital by Buyer or the resolution of any disputes, (i) if Net Working Capital on the Closing Date as so determined is greater than the Target Net Working Capital by more than $25,000, the Merger Consideration shall be increased by such amount and Buyer shall promptly, but no later than 5 days after final determination, pay or cause the Surviving Corporation to pay to each Selling Shareholder such Selling Shareholder's Applicable Percentage of the amount of such excess, together with interest thereon from the Closing Date to the date of payment thereof as determined below, and (ii) if Net Working Capital on the Closing Date as so determined is less than the Target Net Working Capital by more than $25,000, the Shareholders' Representative and the Buyer shall promptly, but no later than 5 days after such final determination, instruct the Escrow Agent in writing to pay to Buyer from the Escrow Account the amount of such difference, together with interest thereon from the Closing Date to the date of payment thereof as determined below.

(d) For the purposes of this Section 2.10, interest will be payable at the applicable federal rate (as defined in Section 1274 of the Code), or, if that rate is no longer established or published, a comparable interest rate. For purposes of this Section 2.10, interest shall be calculated based on a 365 day year and the actual number of days elapsed.

13

Section 2.11 DISSENTING SHARES. Notwithstanding anything in this Agreement to the contrary, shares of ZMP Common Stock that are issued and outstanding immediately prior to the Effective Time and that are held by a stockholder who has the right (to the extent such right is available by law) to demand and receive payment of the fair value of such holder's stock pursuant to California law shall not be converted into the right to receive the Merger Consideration (unless and until such holder shall have failed to perfect or shall have effectively withdrawn or lost such right under California law, as the case may be) (such shares, the "Dissenting Shares"), but the holder thereof shall only be entitled to such rights as are granted by California law. If such holder shall have so failed to perfect or shall have effectively withdrawn or lost such right, such holder's shares of ZMP Common Stock shall thereupon no longer be Dissenting Shares, but shall be deemed to have been converted at the Effective Time into the right to receive the Merger Consideration (without any interest thereon), and the Merger Consideration payable in respect thereof and in respect of all other ZMP Shares shall be adjusted to yield the results that would have obtained if such shares had been treated as ZMP Shares rather than Dissenting Shares at the Closing. If the holder of any shares of ZMP Common Stock shall become entitled to receive payment for such shares pursuant to
Section 1300 of the California Corporations Code ("Section 1300 Payment") then such payment shall be made by the Surviving Corporation with no cost or other liability to any of the Selling Shareholders or the Shareholders' Representative, except as provided or referred to in the next sentence. Pursuant to Section 7.1(4), the Buyer Indemnitees shall be indemnified against all Losses incurred by them (including Section 1300 Payments and payments required hereunder out of the Dissenting Share Amount) in connection with or as a result of the existence of Dissenting Shares at the Closing if and to the extent that such Losses or payments exceeds the Dissenting Share Amount.

Section 2.12 SPECIAL PURCHASE PRICE ADJUSTMENT

Following the Closing, the Merger Consideration shall be adjusted as follows:

(a)(i) If a Boeing Contract is executed and delivered by Boeing and ARA on or prior to the Boeing Determination Date, within 10 business days of such execution and delivery Buyer shall cause to be prepared and delivered to the Shareholders' Representative (x) a statement, along with a copy of a Boeing Contract, and if requested by Shareholders' Representative, and calculations, setting forth the amount due to the Buyer, if any, as a result of the calculations set forth in Section 2.12(a)(iii) or (y) a statement that no amount is due to Buyer as a result of the calculations set forth in Section 2.12(a)(iii).

(ii) Within 10 business days after receipt of a statement delivered pursuant to Section 2.12(a)(i)(x), the Shareholders' Representative shall, in a written notice to the Buyer, either accept such statement or describe in reasonable detail any proposed adjustments and the reasons therefor. If Buyer has not received such notice of proposed adjustments within such 10 business day period, the Shareholders' Representative will be deemed to irrevocably to have accepted such statement. In the event that the Shareholders' Representative and the Buyer are not able to agree on such statement within 10 business days of receipt by Buyer of any adjustments proposed by Shareholders' Representative, such dispute shall be submitted to Arthur Andersen LLP for computation or verification in accordance with this Agreement.

14

(iii) Upon acceptance by the Shareholders' Representative of the statement delivered pursuant to Section 2.12(a)(i)(x) or the resolution of any disputes, if the Proposed Boeing Revenue is less than the Boeing Target Amount, the Merger Consideration will be decreased by an amount equal to the product of (x) the Boeing Target Amount minus the Proposed Boeing Revenue and
(y) the Fixed Multiplier. If the Merger Consideration is so decreased, the Shareholders' Representative and the Buyer shall promptly, but in no event later than five days after such final determination, instruct the Escrow Agent in writing to pay Buyer from the Escrow Account the amount of such decrease.

(b) If no Boeing Contract has been executed and delivered by Boeing and ARA on or prior to the Boeing Determination Date, the Buyer shall cause to be prepared and delivered to Shareholders' Representative a statement pursuant to Section 2.12(a)(i)(x) setting forth the amount due to the Buyer as a result of the calculations set forth in Section 2.12(a)(iii) assuming for purposes of such calculation that Proposed Boeing Revenue equals zero.

(c) Notwithstanding anything to the contrary herein, the parties hereto agree that any amounts payable to the Buyer under or pursuant to this Section 2.12 will be paid solely out of the Escrow Account, in accordance with this Agreement, and none of the Selling Shareholders will have any obligation to make (or otherwise with respect to) any such payments other than from the Escrow Account. Buyer acknowledges that the payments contemplated hereunder may exceed the amount on deposit in the Escrow Account and that such payments may exhaust the Escrow Account and that Buyer shall not be entitled to payment from any other source, including the Glendale Escrow Account.

(d) Notwithstanding anything to the contrary herein, if a part or parts set forth on Schedule A is not set forth in the Boeing Contract as executed and delivered by the parties and, in the Shareholders' Representative's reasonable and good faith judgement, such part or parts may be contained in a subsequent Boeing Contract to be executed and delivered prior to the Boeing Determination Date the Boeing Target Amount shall be recomputed for purposes of the calculation set forth in Section 2.12(iii) to exclude such part or parts. If a subsequent Boeing Contract containing the part or parts so excluded is executed and delivered prior to the Boeing Determination Date, a separate calculation shall be made pursuant to Section 2.12(iii) with respect to such part or parts, utilizing a target amount based solely on such part or parts. If such subsequent Boeing Contract containing the part or parts so excluded is not executed and delivered prior to the Boeing Determination Date, a separate calculation shall be made pursuant to Section 2.12(b) with respect to such part or parts, utilizing a target amount based solely on such part or parts.

(e) Buyer, the Company and ARA agree to use their commercially reasonable efforts to execute and deliver the Boeing Contract and to negotiate its terms and conditions in good faith.

18

copies of the unaudited consolidated balance sheet (the "Interim Balance Sheet") for the Company and ARA at February 20, 1999 and the related statement of operations, cash flow and changes in stockholders' equity for the period then ended (collectively with the Interim Balance Sheet, the "Unaudited Financial Statement" and, together with the Audited Financial Statements, the "Financial Statements"). The Audited Financial Statements have been examined by the Company's Auditors, whose reports thereon are included with such financial statements. The Audited Financial Statements have been prepared in conformity with GAAP, except for changes, if any, required by GAAP and disclosed therein, consistently applied throughout the periods covered thereby. Each statement of operations, cash flow and changes in stockholders' equity in the Audited Financial Statements (i) was prepared in accordance with the books of account and other financial records of the Company and ARA and (ii) presents fairly the results of operations, cash flow and changes in stockholders' equity of the Company and ARA for the periods covered, and each balance sheet (i) was prepared in accordance with the books of account and other financial records of the Company and ARA and (ii) presents fairly the financial condition of the Company and ARA as of its respective date. Such Audited Financial Statements reflect all adjustments necessary for a fair presentation. At the date of the most recent such balance sheet, neither the Company nor ARA had any Liabilities (actual, contingent or accrued) that, in accordance with GAAP, should have been shown or reflected therein but were not.

(ii) The Unaudited Financial Statements have been prepared in conformity with GAAP as used in preparing the Audited Financial Statements, provided that such Unaudited Financial Statements do not include footnotes, and
(i) were prepared in accordance with the books of account and other financial records of the Company and ARA and (ii) present fairly the consolidated financial position of the Company and ARA as of such date and the consolidated results of operations, cash flow and changes in stockholders' equity of the Company and ARA for such period. At February 20, 1999, neither the Company nor ARA had any Liabilities (actual, contingent or accrued) that, in accordance with GAAP as used in preparing the Audited Financial Statements, should have been shown or reflected in such Unaudited Financial Statements but were not except as otherwise described in Section 2.8(a)(iii). Accruals for expenses relating to the transactions contemplated by this Agreement and the other Transaction Documents and for the Success Bonuses reflected on the Interim Balance sheet were $194,000 and $380,000, respectively.

(iii) Since June 26, 1998 neither the Company nor ARA has incurred any Liabilities (whether accrued, absolute, contingent or otherwise) that would be required to be reflected or reserved against in a balance sheet of the Company and ARA prepared in accordance with GAAP as used in preparing the Audited Financial Statements, except Liabilities that are reflected or disclosed in the financial statements referred to in this Section 3.2(c) or were incurred after February 20, 1999 in the ordinary course of business, consistent with past practice. Neither the Company nor ARA has any Liabilities (whether accrued, absolute, contingent or otherwise) that do not relate primarily to the ownership of its assets, the conduct of its Business or its existence as a corporation. Other than the TCW Notes or as set forth on Section 3.2B of the Disclosure Schedule, neither the Company nor ARA has any Liability to any Shareholder of the Company.

The books of account and other financial records of the Company and ARA: (i) reflect all items of income and expense and all assets and Liabilities required to be reflected

19

therein in accordance with GAAP and (ii) are in all material respects complete and correct, and do not contain or reflect any material inaccuracies or discrepancies. Since June 26, 1998, the Company and ARA have maintained systems of internal accounting controls sufficient to provide reasonable assurance that material transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability.

Except to the extent, if any, reserved for on the Unaudited Financial Statements, all Receivables reflected therein arose from the sale of Inventory or services to Persons not affiliated with ARA or the Company and in the ordinary course of the Business consistent with past practice other than (i) notes payable from Collins in the aggregate amount of approximately $512,000 and
(ii) a note payable from a former employee in the approximate amount of $16,000 and except as reserved against on the Unaudited Financial Statements, constitute or will constitute, as the case may be, only valid and, to the best knowledge of the Company and ARA, undisputed claims of the Company or ARA and, to the best knowledge of the Company and ARA, are not subject to valid claims of set off or other defenses or counterclaims other than normal cash discounts accrued in the ordinary course of the Business consistent with past practice.

Subject to amounts reserved therefor on the Unaudited Financial Statements, the values at which all Inventories are carried therein reflect the historical inventory valuation policy of the Company and ARA of stating such Inventories at the lower of cost (determined on the first in, first out method) or market value. Except as set forth in Section 3.2C of the Disclosure Schedule, the Company or ARA, as the case may be, has good and marketable title to the Inventories free and clear of all Encumbrances other than Permitted Encumbrances. The Inventories do not consist of any items held on consignment. Except as set forth on Section 3.2C of the Disclosure Schedule, neither the Company nor ARA is under any obligation or liability with respect to accepting returns of items of Inventory or merchandise in the possession of their customers.

Except as reserved against on the Unaudited Financial Statements, the Inventories do not consist of, in any material amount, items that are obsolete, damaged or slowmoving. The Inventories are in good and merchantable condition, are suitable and usable for the purposes for which they are intended and are in a condition such that they can be sold in the ordinary course of the Business consistent with past practice.

SECTION 4.8 PREPARATION OF TAX RETURNS FOR STRADDLE PERIODS.

(a) Buyer shall prepare and timely file, or cause to be prepared and timely filed, all Tax Returns required to be filed by the Company and ARA for any Straddle Period.

36

With respect to each Tax Return filed with respect to a Straddle Period, Buyer will provide the Shareholders' Representative with a statement (each, a "Straddle Period Statement") setting forth (i) Buyer's calculation of the Tax liability of the Company and ARA allocable to the Deemed Pre-Closing Period (the "Straddle Period Liability"), and (ii) a copy of the Tax Return to be filed with respect to such Straddle Period. Buyer shall deliver such Straddle Period Statement to the Shareholders' Representative no later than 30 days before the due date (including extensions) for filing such Tax Return. The term "Straddle Period" means any taxable period of the Company or ARA that begins before the Closing Date and ends after the Closing Date. Items of income, gain, loss, deduction, and credit for any Straddle Period attributable to the period of time on or before the Closing Date shall be allocated to a deemed Pre-Closing Period that ends on the Closing Date (the "Deemed Pre-Closing Period") using an interim closing-of-the-books method, assuming that the Deemed Pre-Closing Period ended as of the close of business on the Closing Date. In the case of any Taxes that are imposed on a periodic basis (other than Taxes based upon or related to income or receipts), and are payable for a Straddle Period, the portion of such Tax which relates to the Deemed Pre-Closing period shall be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction the numerator of which is the number of days in the Deemed Pre-Closing Period and the denominator of which is the number of days in the entire taxable period.

(b) Within 20 days of receipt of such Straddle Period Statement, the Shareholders' Representative shall, in a written notice to the Buyer, either accept the Straddle Period Statement or describe in reasonable detail any proposed adjustment to any item of income, gain, loss, deduction, or credit on the Straddle Period Statement. Buyer and the Shareholders' Representative shall negotiate in good faith to resolve any disputes over any proposed adjustments to the Straddle Period Statement, provided that if any such dispute is not resolved within 10 days after the Buyer's receipt of the proposed adjustments, Buyer and the Shareholders' Representative shall jointly engage Arthur Andersen LLP or such other mutually acceptable national independent public accounting firm ("Tax Arbitrator") to resolve such dispute, which resolution shall be final and binding upon the parties, and not subject to review or challenge of any kind. The amount of the Straddle Period Liability shall be determined based on (i) the Straddle Period Statement prepared by the Buyer, if the Shareholders' Representative proposes no adjustment or proposes an adjustment but no resolution of the issue is reached between the Shareholders' Representative and the Buyer before the due date (including extensions) for filing the relevant Tax Return, or (ii) the Straddle Period Statement as finally resolved between Shareholders' Representative and the Buyer, if the Shareholders' Representative proposes an adjustment and the Shareholders' Representative and the Buyer reach a resolution, or the Tax Arbitrator reaches a resolution, of the proposed adjustment before the due date (including extensions) for filing such relevant Tax Return. If any final resolution of the proposed adjustment reached after the filing of the relevant Tax Return differs from the Straddle Period Statement filed, then Buyer shall file an amended Tax Return for such Straddle Period in accordance with the determination of the Tax Arbitrator. Any fees and expenses related to the engagement of the Tax Arbitrator shall be borne equally by Buyer, on one hand, and the Selling Shareholders through a payment out of the Escrow Account on the other. Buyer and the Shareholders' Representative will jointly instruct the Escrow Agent, in writing, to make any such payment.

ARTICLE VII

INDEMNITY

SECTION 7.1 INDEMNIFICATION OF BUYER. From and after the Closing, Buyer, Surviving Corporation and their respective directors, officers, employees, Affiliates, agents, advisors, representatives and assigns ("Buyer Indemnitees") shall be indemnified and held harmless by the holders of ZMP Common Stock on the date hereof out of funds in the Escrow Account and/or the Glendale Escrow Account, as the case may be, available therefor, from and against any and all Losses of any such Person, directly or indirectly, as a result of, or based upon or arising from (1) any untruth or inaccuracy of any of the representations or warranties (except to the extent related to Taxes) made by the Company in Section 3.2 of this Agreement or any of the agreements or covenants (except to the extent related to Taxes) made by the Company in Article IV of this Agreement, (2) without duplication, (x) any breach of the covenant to pay any Declared Pre-Closing Income Tax Liability, (y) all Taxes of the Company or ARA relating to Pre-Closing Periods and (z) any Straddle Period Liability

SECTION 7.3 PROCEDURE.

(a) Any party seeking indemnification with respect to any Loss or potential Loss arising from a claim (an "Indemnifiable Claim") asserted by a third party (including a notice of Tax audit or request to waive or extend a statute of limitations applicable to any Tax) shall give written notice to the party required to provide indemnity hereunder (the "Indemnifying Party"). Written notice to the Indemnifying Party of the existence of a third-party Indemnifiable Claim shall be given by the Indemnified Party within 30 days after its receipt of a written assertion of liability from the third party, including in the case of tax matters, written notice of any tax audit that might result in such a claim. The failure of any Indemnified Party to give

44

timely notice hereunder shall not affect rights to indemnification hereunder, except and only to the extent that the Indemnifying Party demonstrates actual damage caused by such failure.

(b) If any claim, demand or liability is asserted by any third party against any Person entitled to indemnification hereunder (the "Indemnified Party"), the Indemnifying Party shall defend any actions or proceedings brought against the Indemnified Party in respect of matters embraced by the indemnity. If, after 10 business days following a written request by the Indemnified Party to defend any action or proceeding, the Indemnifying Party neglects to defend the Indemnified Party, the Indemnified Party may defend, compromise or settle the claim on behalf of and for the account and risk of the Indemnifying Party, who shall be bound by the result. In all cases, the party without the right to control the defense of the Indemnifiable Claim may participate in the defense at its own expense.

(c) Notwithstanding anything in this Section 7.3 to the contrary except as set forth in Section 7.3(b), neither the Indemnifying Party nor the Indemnified Party shall, without the written consent of the other Party, settle or compromise any Indemnifiable Claim or permit a default or consent to entry of any judgment unless the claimant and such party provide to such other Party an unqualified release from all liability in respect of the Indemnifiable Claim. Notwithstanding the foregoing, if a settlement offer solely for money damages is made by the applicable third party claimant, and the Indemnifying Party notifies the Indemnified Party in writing of the Indemnifying Party's willingness to accept the settlement offer and, subject to the limitations of Sections 7.5 and 7.6, pay the amount called for by such offer, and the Indemnified Party declines to accept such offer, the Indemnified Party may continue to contest such Indemnifiable Claim, free of any participation by the Indemnifying Party, and the amount of any ultimate liability with respect to such Indemnifiable Claim that the Indemnifying Party has an obligation to pay hereunder shall be limited to the lesser of (A) the amount of the settlement offer that the Indemnified Party declined to accept plus the Losses of the Indemnified Party relating to such Indemnifiable Claim through the date of its rejection of the settlement offer or (B) the aggregate Losses of the Indemnified Party with respect to such Indemnifiable Claim. If the Indemnifying Party makes any payment on any Indemnifiable Claim, the Indemnifying Party shall be subrogated, to the extent of such payment, to all rights and remedies of the Indemnified Party to any insurance benefits or other claims of the Indemnified Party with respect to such Indemnifiable Claim.

SECTION 7.4 SURVIVAL.

(a) Each of the representations, warranties, covenants and agreements contained in or made pursuant to this Agreement or any other Transaction Document shall expire on the first anniversary of the Closing, except that the representations contained in Section 3.2(q) and the covenants and agreements contained in clauses (2), (3), (4) and (5) of Section 7.1 shall survive the Closing and shall terminate on the third anniversary of the Closing (the period from the date hereof until the date of the termination of the related representation, warranty, covenant or agreement is referred to herein as the "Survival Period"). Except with respect to any matter as to which a claim has been asserted by notice to the other party that is pending or unresolved at the end of the pertinent Survival Period, the parties intend to shorten the statute of limitations and agree that no claims or causes of action may be brought against any of the Selling Shareholders, the Company, Acquisition or Buyer based upon, directly or indirectly, any of the

45

representations, warranties, covenants or agreements (including covenants and agreements to indemnify) contained in or made pursuant to this Agreement or any other Transaction Document after the expiration of the pertinent Survival Period or any termination of this Agreement.

(b) The indemnifications provided for hereunder shall take effect upon Closing and shall remain in effect during the relevant Survival Period. Any matter as to which a claim has been asserted by notice to the other party that is pending or unresolved at the end of the pertinent Survival Period shall continue to be covered by this Article VII notwithstanding the expiration of the Survival Period with respect to such claim or the expiration of any applicable statute of limitations (which the parties hereby waive) until such matter is finally terminated or otherwise formally resolved by the parties under this Agreement or by a court of competent jurisdiction and any amounts payable hereunder are finally determined and paid. Any written notice delivered by a party with respect to a claim for indemnification shall set forth with specificity the basis of the claim and a reasonable estimate of the amount thereof.

SECTION 7.5 LIMITATIONS ON INDEMNIFICATION OF BUYER. In addition to the other limitations set forth herein, including the limitations set forth in Sections 7.1 and 7.4, Buyer's right to indemnification pursuant to this Article VII is subject to the following limitations:

(a) No indemnification shall be made unless the aggregate amount of Losses sustained by Buyer Indemnitees under Sections 7.1(1) and (5) (such amount, "Buyer Losses") exceeds $250,000 and, in such event, indemnification shall be made only to the extent Buyer Losses exceed $250,000 (it being understood that any Buyer Losses sustained prior to the expiration of a Survival Period shall continue to be counted for purposes of this Section 7.5(a) in determining whether Buyer is entitled to indemnification). The limitation under the first sentence of this Section 7.5(a) shall not apply to Buyer's right to indemnification pursuant to Section 7.1(2), (3) and (4) (it being understood that in all such cases, Buyer shall be entitled to seek indemnity immediately) and any Losses for which the Buyer is indemnified under such sections shall not count towards determining whether Buyer Losses exceed $250,000.

(b) Notwithstanding anything to the contrary herein, the parties hereto agree that any amounts payable under or pursuant to this Article VII (other than pursuant to Section 7.1(5)) to any Buyer Indemnitee or in respect of any Buyer Losses (including any settlement of any Indemnifiable Claims in accordance with Section 7.3(c)) will be paid solely out of the Escrow Account, in accordance with this Agreement and the Escrow Agreement, and none of the Selling Shareholders will have any obligation to make (or otherwise with respect to) any such payments other than from the Escrow Account. In addition, notwithstanding anything to the contrary herein, the parties hereto agree that any amounts payable or pursuant to Section 7.1(5) to any Buyer Indemnitee or in respect of Buyer Losses (including any settlement of any Indemnifiable Claims in accordance with Section 7.3(c)) will be solely out of the Escrow Account and the Glendale Escrow Account in accordance with this Agreement and the Escrow Agreement, and none of the Selling Shareholders will have any obligation to make or otherwise with respect to any such payments other than from the Escrow Account and the Glendale Escrow Account.

46

(c) The amount of any Buyer Losses shall be reduced by any amount received by Buyer Indemnitees with respect thereto under any insurance coverage or for any other party alleged to be responsible therefor. Buyer Indemnitees shall use commercially reasonable efforts to collect any amounts available under such insurance coverage and from such other party alleged to have responsibility. If a Buyer Indemnitee receives an amount under insurance coverage or from such other party with respect to Buyer Losses at any time subsequent to any indemnification pursuant to this Section 7.5, then such Buyer Indemnitee shall promptly reimburse the Escrow Account for any payment made, including expenses incurred, from the Escrow Account in connection with providing such indemnification up to such amount received by the Buyer Indemnitee.

SECTION 7.6 LIMITATIONS ON INDEMNIFICATION BY BUYER. In addition to the other limitations set forth herein, including the limitations set forth in Sections 7.2 and 7.4, Buyer's obligation to indemnify pursuant to this Article VII is subject to the following limitations:

(a) No indemnification shall be made by Buyer unless the aggregate amount of Losses claimed by Seller Indemnitees under Section 7.2 (such amount, "Seller Losses") exceeds $250,000 and, in such event, indemnification shall be made by the Buyer only to the extent Seller Losses exceed $250,000.

(b) The amount of any Seller Losses shall be reduced by any amount received by Seller Indemnitees with respect thereto under any insurance coverage or for any other party alleged to be responsible therefor. Seller Indemnitees shall use best efforts to collect any amounts available under such insurance coverage and from such other party alleged to have responsibility. If a Seller Indemnitee receives an amount under insurance coverage or from such other party with respect to Seller Losses at any time subsequent to any indemnification provided by Buyer pursuant to this Section 7.6, then such Seller Indemnitee shall promptly reimburse Buyer for any payment made or expense incurred by Buyer in connection with providing such indemnification up to such amount received by the Seller Indemnitee.

SECTION 7.7 NO SPECULATIVE DAMAGES. Notwithstanding anything to the contrary elsewhere in this Agreement, no party (or any of its Affiliates) shall, in any event, be liable to the other party (or any of its Affiliates) for any speculative damages or remote consequential damages of such other party (or any of its Affiliates), including loss of speculative future revenue or income, or loss of business reputation or opportunity relating to the breach or alleged breach hereof.

SECTION 7.8 EXCLUSIVE REMEDY. The remedies provided for in this Article VII, as limited by the provisions of this Article VII, shall constitute the sole and exclusive remedy for any post-Closing claims made for breach of this Agreement or otherwise in connection with the transactions contemplated hereby; provided that nothing herein shall extinguish or limit any claim based on fraud.

SECTION 7.9 ADJUSTMENT TO MERGER CONSIDERATION. Any payment pursuant to this Article VII shall be treated for Tax purposes as an adjustment to the Merger Consideration.

47

SECTION 7.10 TAX ADJUSTMENTS. Any amounts payable by the Indemnifying Party to or on behalf of an Indemnified Party in respect of a Loss shall be adjusted as follows. The Indemnified Party shall reimburse the Indemnifying Party an amount equal to the present value amount of the net reduction in any year in the liability for Taxes of the Indemnified Party or any member of a consolidated or combined tax group of which the Indemnified Party is, or was at any time, part, which reduction will be realized (either through the reduction of a Tax liability or the increase of a Tax loss or credit) with respect to any period after the Closing Date and which reduction would not have been realized but for the amounts paid (or any audit adjustment or deficiency with respect thereto, if applicable) in respect of a Loss for which the Indemnified Party is indemnified by the Indemnifying Party pursuant to this Agreement, or amounts paid by the Indemnified Party pursuant to this paragraph (a "Net Tax Benefit"). The present value amount of the Net Tax Benefit shall be determined by: (i) using a discount rate equal to the mid-term applicable federal rate (under Section 1274(d) of the Code) in effect on the date by which the payment subject to the Net Tax Benefit adjustment is due, (ii) discounting back to the date by which the payment subject to the Net Tax Benefit adjustment is due and (iii) using reasonable assumptions regarding the date (or dates) on which such Net Tax Benefit will be realized, which assumptions must be verified by an independent certified public accountant chosen by the Indemnifying Party if requested by the Indemnifying Party. Each party agrees to provide the other party or their designated representatives with assistance and such documents and records reasonably requested by them that are relevant to their ability to determine when a Net Tax Benefit will be realized, including but not limited to copies of Tax Returns, estimated tax payments, schedules, and related supporting documents. In the event the parties are unable to agree on the amount, the parties shall engage the Tax Arbitrator to resolve the matter, whose decision shall be final and binding upon the parties and not subject to review or challenge of any kind.

ARTICLE VIII

ESCROW

SECTION 8.1 ASSERTION OF INDEMNIFIABLE CLAIMS. From time to time during the pertinent Survival Period, Buyer (on its own behalf or on behalf of the Company) or its successors or assigns may assert a claim that it or a Buyer Indemnitee is entitled to indemnification pursuant to Section 7.1 (any such claim for indemnification under Section 7.1(1), (2), (3) or (4), a "Claim" and any such claim for indemnification under Section 7.1(5), a "Glendale Claim") and demand satisfaction thereof out of the Escrow Account and/or the Glendale Escrow Account by sending a written notice to the Shareholders' Representative. If the Shareholders' Representative shall receive such notice from Buyer before any termination of the pertinent Survival Period, the notice shall be deemed to represent a pending Claim (or Claims) or Glendale Claim (or Claims), as the case may be. Any such notice of a Claim or a Glendale Claim shall be effective only if the Shareholders' Representative receives a certificate from an executive officer of Buyer to the effect that the Buyer Indemnitees are entitled to indemnification therefor pursuant to Article VII, along with a reasonable description of the Claim or Glendale Claim, the relevant representations, warranties, covenants or agreements for the breach of which indemnification is being sought, the dollar amount thereof, copies of any documentation related thereto and any other information reasonably requested by Shareholders' Representative to support such Claim or Glendale Claim.

(b) Upon the final resolution of any Glendale Claim, Buyer and Shareholders' Representative shall jointly instruct Escrow Agent, in writing, to make the pertinent payment to Buyer from the Glendale Escrow Account and/or the Escrow Account, as applicable.

SECTION 8.3 PERIODIC PAYMENTS FROM THE ESCROW ACCOUNTS.

49

(c) If on or at anytime after the date that is 18 months after the Closing, the amount on deposit in the Glendale Escrow Account exceeds the amount of all then pending Glendale Claims to be paid from the Glendale Escrow Account, Buyer and Shareholders' Representative shall jointly instruct the Escrow Agent, in writing, to pay to the Selling Shareholders in proportion to their Applicable Percentages, the amount of such excess.

(d) No less frequently than quarterly, Buyer and the Shareholders' Representative shall jointly instruct the Escrow Agent, in writing, to pay to the Selling Shareholders in proportion to their respective Applicable Percentages, 50% of the earnings on amounts on deposit in the Escrow Account, provided that prior to any such payments all expenses due and owing to the Escrow Agent shall be paid in full.

(e) If the Shareholders' Representative so requests, any instruction to the Escrow Agent to pay any amount to the Selling Shareholders may state that a portion thereof should instead be paid to the Shareholders' Representative to defray the Shareholders' Representative's past or future out-of-pocket expenses in carrying out its responsibilities hereunder.

(f) Whenever the Shareholders Representative and/or the Selling Shareholders shall be entitled to receive a distribution from the Escrow Account or the Glendale Escrow Account (other than a distribution of current earnings) the Escrow Agent shall first pay out of such distribution the amount of the incremental Success Bonuses due to the persons entitled to receive Success Bonuses as a result of any such proposed distribution and no amount shall be paid to any Selling Shareholder unless and until all such incremental Success Bonuses are so paid.

SECTION 9.18 SEVERABILITY. If any provision of this Agreement is determined to be invalid, illegal or unenforceable by any Governmental Entity, the remaining provisions of this Agreement to the extent permitted by Law shall remain in full force and effect, unless doing so would result in an interpretation of this Agreement which is manifestly unjust.

Any action or decision taken by the Shareholders' Representative shall be binding and conclusive on such holders of the ZMP Shares, and may be relied upon by Buyer. By accepting the Merger Consideration, each Selling Shareholder will agree to indemnify and hold harmless the Shareholders' Representative for any act or failure to act of Shareholders' Representative taken on behalf of such Person, except for the Shareholders' Representative's gross negligence or willful misconduct. In the event that the Shareholders' Representative becomes no longer able to carry out its functions, a replacement Shareholders' Representative will be appointed if prior to the Effective Time, by the Board of Directors of the Company, and, if at or after the Effective Time, by majority vote of the Selling Shareholders based upon the number of the ZMP Shares held immediately prior to the Effective Time by each such Person. From time to time the Shareholders' Representative shall be entitled to withhold from any amounts payable to the Selling Shareholders such amounts (or estimated amounts) as it deems appropriate to cover any expenses incurred by or on behalf of any of the Company, the Selling Shareholders and the Shareholders' Representative related to this Agreement, the Escrow Agreement or any other Transaction Document.

SECTION 9.20 ENTIRE AGREEMENT. This Agreement, the Voting Agreement and the Escrow Agreement constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, other than the Confidentiality Agreement, which shall survive the execution and delivery of this Agreement.

The Escrow Agent shall hold $__________ of such funds in one account (the "Escrow Account") and

B-1

$__________ of such funds in a separate account (the "Glendale Escrow Account") in accordance with the terms of this Escrow Agreement.

SECTION 3. INVESTMENT. Unless jointly instructed otherwise in writing by Buyer and Shareholders' Representative, Escrow Agent shall invest the Escrow Funds subject to the following limitations:

(a) DEBT INVESTMENTS. Escrow Agent shall invest the Escrow Funds pursuant to joint written instructions from Buyer and the Shareholders' Representative.

(b) INCOME. All income on the Escrow Account and the Glendale Escrow Account actually earned and not distributed pursuant to

(1) Written instructions from each of the Shareholders' Representative and Buyer; or

(2) A certified order or ruling from a court ordering or instructing it to do so.

B-2

Distributions shall be made as promptly as practicable and in any event within 5 days after receipt of any such instruction, order or ruling even if Escrow Agent has been advised that an appeal or other relief is being sought, so long as it has not received actual service of a stay of such order or ruling pending appeal.

SECTION 5. NO TRANSFER OF INTEREST IN ESCROW ACCOUNTS. The Selling Shareholders may assign or transfer, such Person's interest in the Escrow Account and the Glendale Escrow Account in whole or in part. Except as set forth in the immediately preceding sentence, no party hereto may transfer or assign any of its interest herein of obligations hereunder.

SECTION 7. EXPENSES. Escrow Agent shall be compensated for services hereunder from the income on the Escrow Funds in accordance with a fee letter heretofore delivered to Buyer and Selling Shareholders and shall be reimbursed for its ordinary out-of-pocket expenses including, but not by way of limitation, the fees and costs of attorneys or agents that it may find necessary to engage in performance of its duties hereunder and costs arising from the defense of any suits in which Escrow Agent is named as a defendant in its capacity as Escrow Agent. If it shall become necessary that Escrow Agent shall perform extraordinary services, it shall be entitled to reasonable extra compensation therefor and to reimbursement for reasonable and necessary extraordinary out-of-pocket expenses unless such extraordinary service or expense is occasioned by the neglect or breach of this Escrow Agreement by Escrow Agent.

SECTION 8. NOTICES. Any notice or other communication related hereto must be given in writing and (a) delivered in person, (b) transmitted by facsimile, (c) mailed by certified or registered mail, postage prepaid, receipt requested or (d) overnight delivery service, given to the party at its address stated on the signature pages of this Agreement or at any other address as the party may specify for this purpose by notice to the other party.

(c) Buyer and Selling Shareholders jointly and severally agree to indemnify and hold harmless Escrow Agent from all losses, costs and expenses that may be incurred as a result of its involvement in any litigation arising from the performance of its duties hereunder, provided that such losses costs and expenses shall not have resulted from any action taken or omitted by Escrow Agent and for which it shall have been adjudged negligent or engaged in misconduct or have acted in bad faith or willful disregard of its duties.

As adopted on April 23, 1999

ARTICLE I

SHAREHOLDERS

Section 1.01. ANNUAL MEETINGS. The annual meeting of the shareholders of the Corporation for the election of directors and for the transaction of such other business as properly may come before such meeting shall be held at such place, either within or without the State of California, and at such date and hour, as may be fixed from time to time by resolution of the Board of Directors and set forth in the notice or waiver of notice of the meeting.

Section 1.02. SPECIAL MEETINGS. Special meetings of the shareholders may be called at any time by the President (or, in the event of his absence or disability, by any Vice President), or by the Board of Directors. A special meeting shall be called by the President (or, in the event of his absence or disability, by any Vice President), or by the Secretary, immediately upon receipt of a written request therefor by shareholders holding in the aggregate not less than 10% of the outstanding shares of the Corporation at the time entitled to vote at any meeting of the shareholders. If such officers or the Board of Directors shall fail to call such meeting within 20 days after receipt of such request, any shareholder executing such request may call such meeting to be held at a time requested by the person or persons calling the meeting, not less than 35 nor more than 60 days after the receipt of the request. Such special meetings of the shareholders shall be held at such places, within or without the State of California, as shall be specified in the respective notices or waivers of notice thereof.

Section 1.03. NOTICE OF MEETINGS; WAIVER. The Secretary or any Assistant Secretary shall cause written notice of the place, date and hour of each meeting of the shareholders, and, (i) in the case of a special meeting, the general nature of the business to be transacted, or (ii) in the case of the annual meeting those matters which the Board of Directors, at the time of giving the notice, intends to present for action by the shareholders, to be given personally or by first-class mail, not less than ten nor more than sixty days prior to the meeting, to each shareholder of record entitled to vote at such meeting. The notice of any meeting at which directors are to be elected shall include the name of any nominee or nominees which, at the time of the notice, management intends to present for election.

If action is proposed to be taken at any meeting for approval of (i) a contract or transaction in which a director has a direct or indirect financial interest, pursuant to Section 310 of the Corporations Code of California, (ii) an amendment of the articles of incorporation, pursuant to Section 902 of such Code, (iii) a reorganization of the corporation, pursuant to Section 1201 of such Code, (iv) a voluntary dissolution of the corporation, pursuant to Section


1900 of such Code, or (v) a distribution in dissolution other than in accordance with the rights of outstanding preferred shares pursuant to Section 2007 of such Code, the notice shall also state the general nature of such proposal.

If such notice is mailed, it shall be deemed to have been given to a shareholder when deposited in the United States mail, postage prepaid, directed to the shareholder at his address as it appears on the record of shareholders of the Corporation, or, if he shall have filed with the Secretary of the Corporation a written request that notices to him be mailed to some other address, then directed to him at such other address. If no such address appears on the corporation's books or has been so given, notice shall be deemed to have been given if sent by first-class mail or telegraphic or other written communication to the corporation's principal executive office, or if published at least once in a newspaper of general circulation in the county where such office is located.

If any notice addressed to a shareholder at the address of such shareholder appearing on the books of the corporation is returned to the corporation by the United States Postal Service marked to indicate that the United States Postal Service is unable to deliver the notice to the shareholder at such address, all future notices or reports shall be deemed to have been duly given without further mailing if the same shall be available to the shareholder upon written demand of the shareholder at the principal executive office of the corporation for a period of one year from the date of the giving of such notice. Such further notice shall be given as may be required by law.

No notice of any meeting of shareholders need be given to any shareholder who submits a signed waiver of notice, whether before or after the meeting. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the shareholders need be specified in a written waiver of notice. The attendance of any shareholder at a meeting of shareholders shall constitute a waiver of notice of such meeting, except when the shareholder attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business on the ground that the meeting is not lawfully called or convened.

An affidavit of the mailing or other means of giving any notice of any shareholders' meeting shall be executed by the Secretary, Assistant Secretary or any transfer agent of the corporation giving such notice, and shall be filed and maintained in the minute book of the corporation.

Section 1.04. QUORUM. Except as otherwise required by law or by the Certificate of Incorporation, the presence in person or by proxy of the holders of record of a majority of the shares entitled to vote at a meeting of shareholders shall constitute a quorum for the transaction of business at such meeting.

Section 1.05. VOTING. If, pursuant to Section 5.05 of these By-Laws, a record date has been fixed, every holder of record of shares entitled to vote at a meeting of shareholders

2

shall be entitled to one vote for each share outstanding in his name on the books of the Corporation at the close of business on such record date. If no record date has been fixed, then every holder of record of shares entitled to vote at a meeting of shareholders shall be entitled to one vote for each share of stock standing in his name on the books of the Corporation at the close of business on the day next preceding the day on which notice of the meeting is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held.

Any shareholder entitled to vote on any matter (other than the election of directors) may vote part of the shares in favor of the proposal and refrain from voting the remaining shares or vote them against the proposal, but, if the shareholder fails to specify the number of shares such shareholder is voting affirmatively, it will be conclusively presumed that the shareholder's approving vote is with respect to all shares such shareholder is entitled to vote. If a quorum is present, the affirmative vote of the majority of the shares represented at the meeting and voting on any matter (other than the election of directors), provided that the shares voting affirmatively must also constitute at least a majority of the required quorum, shall be the act of the shareholders, unless the vote of a greater number or voting by classes is required by the California General Corporation Law or the articles of incorporation.

At a shareholders' meeting involving the election of directors, no shareholder shall be entitled to cumulate votes (i.e., cast for any candidate a number of votes greater than the number of the shareholder's shares) unless such candidate or candidates' names have been placed in nomination prior to commencement of the voting and a shareholder has given notice prior to commencement of the voting of the shareholder's intention to cumulate votes. If any shareholder has given such notice, then every shareholder entitled to vote may cumulate such shareholder's votes for candidates in nomination and give one candidate a number of votes equal to the number of directors to be elected multiplied by the number of votes to which such shareholder's shares are entitled, or distribute the shareholder's votes on the same principle among any or all of the candidates, as the shareholder thinks fit. The candidates receiving the highest number of votes, up to the number of directors to be elected, shall be elected.

Section 1.06. VOTING BY BALLOT.

Section 1.07. ADJOURNMENT.

Notice of any adjourned meeting of the shareholders of the Corporation need not be given if the place, date and hour thereof are announced at the meeting at which the adjournment is taken, provided, however, that if the adjournment is for more than thirty days, or if after the adjournment a new record date for the adjourned meeting is fixed pursuant to Section 5.05 of these By-Laws, a notice of the adjourned

3

meeting, conforming to the requirements of Section 1.03 hereof, shall be given to each shareholder of record entitled to vote at such meeting. At any adjourned meeting at which a quorum is present, any business may be transacted that might have been transacted on the original date of the meeting.

Section 1.08. PROXIES.

A proxy must be filed with the Secretary of the corporation. No such proxy shall be voted or acted upon after the expiration of eleven months from the date of such proxy, unless such proxy provides for a longer period. Every proxy shall be revocable at the pleasure of the shareholder executing it, except in those cases where applicable law provides that a proxy shall be irrevocable. A shareholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by filing an instrument in writing revoking the proxy or by filing another duly executed proxy bearing a later date with the Secretary. Proxies by telegram, cablegram or other electronic transmission must either set forth or be submitted with information from which it can be determined that the telegram, cablegram or other electronic transmission was authorized by the shareholder. Any copy, facsimile telecommunication or other reliable reproduction of a writing or transmission created pursuant to this section may be substituted or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission.

The order of business and all other matters of procedure at every meeting of shareholders may be determined by such presiding officer.

Section 1.10. CONSENT OF SHAREHOLDERS IN LIEU OF MEETING. To the fullest extent permitted by law, whenever the vote of shareholders at a meeting thereof is required or permitted to be taken for or in connection with any corporate action,

4

such action may be taken without a meeting, without prior notice and without a vote of shareholders, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be filed with the Secretary of the corporation and shall be maintained in the corporate records. In the case of election of directors, such consent shall be effective only if signed by the holders of all outstanding shares entitled to vote for the election of directors; provided, however, that a director may be elected at any time to fill a vacancy not created by removal and not filled by the directors by the written consent of the holders of a majority of the outstanding shares entitled to vote for the election of directors.

Every written consent shall bear the date of signature of each shareholder or member who signs the consent and no written consent shall be effective to take the corporate action referred to therein unless, within sixty days of the earliest dated consent delivered in the manner required by law to the Corporation, written consents signed by a sufficient number of holders or members to take action are delivered to the Corporation. Any shareholder giving a written consent, or the shareholder's proxy holders, or a transferee of the shares or a personal representative of the shareholder or their respective proxy holder, may revoke the consent by a writing received by the Secretary of the corporation prior to the time that written consents of the number of shares required to authorize the proposed action have been filed with the Secretary.

The shares of the Corporation shall be represented by certificates, provided that the Board of Directors may provide by resolution or resolutions that some or all of any or all classes or series of the stock of the Corporation shall be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until each certificate is surrendered to the Corporation. Notwithstanding the adoption of such a resolution by the Board of Directors, every holder of stock in the Corporation represented by certificates and upon request every holder of uncertificated shares shall be entitled to have a certificate signed by, or in the name of the Corporation, by the President or a Vice President, and by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary, representing the number of shares registered in certificate form.

The Board of Directors may require the owner of such lost, stolen or destroyed certificate, or his legal representative, to give the Corporation a bond sufficient to indemnify it against any claim that may be made against it on account of the alleged loss, theft or destruction of any such certificate or the issuance of any such new certificate.

Section 5.04. TRANSFER OF STOCK. Upon surrender to the Corporation or the transfer agent of the Corporation of a certificate for shares, duly endorsed or accompanied by appropriate evidence of succession, assignment or authority to transfer, the Corporation shall issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books.

Subject to the provisions of the Certificate of Incorporation and these By-Laws, the Board of Directors may prescribe such additional rules and regulations as it may deem appropriate relating to the issue, transfer and registration of shares of the Corporation.

Section 5.05. RECORD DATE. In order to determine the shareholders entitled to notice of or to vote at any meeting of shareholders or any adjournment thereof or entitled to give consent to corporate action without a meeting, the Board of Directors may fix, in advance, a record date, which record date shall not precede the date on which the resolution fixing the record date is adopted by the Board of Directors, and which shall not be more than sixty nor less than ten days before the date of such meeting nor more than sixty days prior to such action without a meeting. A determination of shareholders of record entitled to notice of or to vote at a meeting of shareholders shall apply to any adjournment of the meeting, provided, however, that the Board of Directors may fix a new record date for the adjourned meeting. If no record date has been fixed by the Board of Directors, the record date for determining shareholders entitled to notice of or to vote at a meeting of shareholders shall be at the close of business on the business day next preceding the day on which notice if given or, if notice is waived, at the close of business on the business day next preceding the day on which the meeting is held.

In order that the Corporation may determine the shareholders entitled to consent to corporate action in writing without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than ten days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. If no record date has been fixed by the Board of Directors, the record date for determining shareholders entitled to consent to corporate action in writing without a meeting, (i) when no prior action by the Board has been taken, shall be the day on which the first written consent is given, or (ii) when prior action of the

15

Board has been taken, shall be at the close of business on the day on which the Board adopts the resolution relating thereto, or the sixtieth (60th) day prior to the date of such other action, whichever is later.

In order that the Corporation may determine the shareholders entitled to receive payment of any dividend or other distribution or allotment of any rights of the shareholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purpose of any other lawful action (other than action by shareholders by written consent without a meeting), the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than sixty days prior to such action. If no record date is fixed, the record date for determining shareholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto, (i) when no prior action by the Board has been taken, shall be the day on which the first written consent is given, or (ii) when prior action of the Board has been taken, shall be at the close of business on the day on which the Board adopts the resolution relating thereto, or the sixtieth (60th) day prior to the date of such other action, whichever is later.

Section 5.06. REGISTERED SHAREHOLDERS. Prior to due surrender of a certificate for registration of transfer, the Corporation may treat the registered owner as the person exclusively entitled to receive dividends and other distributions, to vote, to receive notice and otherwise to exercise all the rights and powers of the owner of the shares represented by such certificate, and the Corporation shall not be bound to recognize any equitable or legal claim to or interest in such shares on the part of any other person, whether or not the Corporation shall have notice of such claim or interests. Whenever any transfer of shares shall be made for collateral security, and not absolutely, it shall be so expressed in the entry of the transfer if, when the certificates are presented to the Corporation for transfer or uncertificated shares are requested to be transferred, both the transferor and transferee request the Corporation to do so.

Section 5.07. TRANSFER AGENT AND REGISTRAR. The Board of Directors may appoint one or more transfer agents and one or more registrars, and may require all certificates representing shares to bear the signature of any such transfer agents or registrars.

ARTICLE VI

INDEMNIFICATION

Section 6.01. NATURE OF INDEMNITY. The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was or has agreed to become a director or officer of the Corporation, or is or was serving or has agreed to serve at the request of the Corporation as a director or officer, of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any

16

action alleged to have been taken or omitted in such capacity, and may indemnify any person who was or is a party or is threatened to be made a party to such an action, suit or proceeding by reason of the fact that he is or was or has agreed to become an employee or agent of the Corporation, or is or was serving or has agreed to serve at the request of the Corporation as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees) , judgments, fines and amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with such action, suit or proceeding and any appeal therefrom, if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding had no reasonable cause to believe his conduct was unlawful; except that in the case of an action or suit by or in the right of the Corporation to procure a judgment in its favor (1) such indemnification shall be limited to expenses (including attorneys' fees) actually and reasonably incurred by such person in the defense or settlement of such action or suit, and (2) no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

The termination of any action, suit or proceeding by judgment, order settlement, conviction, or upon a plea of NOLO CONTENDERE or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

Section 6.02. SUCCESSFUL DEFENSE. To the extent that a director, officer, employee or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section 6.01 hereof or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith.

Section 6.03. DETERMINATION THAT INDEMNIFICATION IS PROPER. Any indemnification of a director or officer of the Corporation under Section 6.01 hereof (unless ordered by a court) shall be made by the Corporation unless a determination is made that indemnification of the director or officer is not proper in the circumstances because he has not met the applicable standard of conduct set forth in Section 6.01 hereof. Any indemnification of an employee or agent of the Corporation under Section 6.01 hereof (unless ordered by a court) may be made by the Corporation upon a determination that indemnification of the employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Section 6.01 hereof. Any such determination shall be made:

(1) by the Board of Directors by a majority vote of a quorum consisting of

17

directors who were not parties to such action, suit or proceeding, or

(2) if such a quorum is not obtainable, or, even if obtainable a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or

(3) by the shareholders, with the shares owned by the person to be indemnified not being entitled to vote thereon, or

(4) by the court in which the proceeding is or was pending upon application made by the corporation or the agent or the attorney or other person rendering services in connection with the defense, whether or not the application by the agent, attorney or other person is opposed by the corporation.

Section 6.04. ADVANCE PAYMENT OF EXPENSES. Expenses (including attorneys' fees) incurred by a director or officer in defending any civil, criminal, administrative or investigative action, suit or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation as authorized in this Article. Such expenses (including attorneys' fees) incurred by other employees and agents may be so paid upon such terms and conditions, if any, as the Board of Directors deems appropriate. The Board of Directors may authorize the Corporation's counsel to represent such director, officer, employee or agent in any action, suit or proceeding, whether or not the Corporation is a party to such action, suit or proceeding.

No indemnification or advance shall be made under this section, except as provided in Section 6.02 or paragraph (4) of Section 6.03, in any circumstance where it appears: (1) that it would be inconsistent with a provision of the articles, bylaws, a resolution of the shareholders, or an agreement in effect at the time of the accrual of the alleged cause of action asserted in the proceeding in which the expenses were incurred or other amounts were paid, which prohibits or otherwise limits indemnification or (2) that it would be inconsistent with any condition expressly imposed by a court in approving a settlement.

Section 6.05. PROCEDURE FOR INDEMNIFICATION OF DIRECTORS AND OFFICERS. Any indemnification of a director or officer of the Corporation under Sections 6.01 and 6.02, or advance of costs, charges and expenses to a director or officer under Section 6.04 of this Article, shall be made promptly, and in any event within 30 days, upon the written request of the director or officer. If a determination by the Corporation that the director or officer is entitled to indemnification pursuant to this Article is required, and the Corporation fails to respond within sixty days to a written request for indemnity, the Corporation shall be deemed to have approved such request. If the Corporation denies a written request for indemnity or advancement of expenses, in whole or in part, or if payment in full pursuant to such request is not made within 30 days, the right to indemnification or advances as granted by this Article shall be enforceable by

18

the director or officer in any court of competent jurisdiction. Such person's costs and expenses incurred in connection with successfully establishing his right to indemnification, in whole or in part, in any such action shall also be indemnified by the Corporation. It shall be a defense to any such action (other than an action brought to enforce a claim for the advance of costs, charges and expenses under Section 6.04 of this Article where the required undertaking, if any, has been received by the Corporation) that the claimant has not met the standard of conduct set forth in Section 6.01 of this Article, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, its independent legal counsel, and its shareholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he has met the applicable standard of conduct set forth in Section 6.01 of this Article, nor the fact that there has been an actual determination by the Corporation (including its Board of Directors, its independent legal counsel, and its shareholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

Section 6.06. SURVIVAL; PRESERVATION OF OTHER RIGHTS. The foregoing indemnification provisions shall be deemed to be a contract between the Corporation and each director, officer, employee and agent who serves in any such capacity at any time while these provisions as well as the relevant provisions of the California Corporation Law are in effect and any repeal or modification thereof shall not affect any right or obligation then existing with respect to any state of facts then or previously existing or any action, suit or proceeding previously or thereafter brought or threatened based in whole or in part upon any such state of facts. Such a "contract right" may not be modified retroactively without the consent of such director, officer, employee or agent.

The indemnification provided by this Article VI shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any by-law, agreement, vote of shareholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

Section 6.07. INSURANCE. The Corporation shall purchase and maintain insurance on behalf of any person who is or was or has agreed to become a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him or on his behalf in any such capacity, or arising out of his status as such, whether or not the Corporation would have the power to indemnify him against such liability under the provisions of this Article, PROVIDED that such insurance is available on acceptable terms, which determination shall be made by a vote of a majority of the entire Board of Directors.

19

Section 6.08. SEVERABILITY. If this Article or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each director or officer and may indemnify each employee or agent of the Corporation as to costs, charges and expenses (including attorneys' fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative, including an action by or in the right of the Corporation, to the fullest extent permitted by any applicable portion of this Article that shall not have been invalidated and to the fullest extent permitted by applicable law.

ARTICLE VII

OFFICES

Section 7.01. PRINCIPAL OFFICES. The Board of Directors shall fix the location of the principal executive office of the corporation at any place within or outside the State of California. If the principal executive office is located outside this state, and the corporation has one or more business offices in this state, the Board of Directors shall likewise fix and designate a principal business office in the State of California.

Section 7.02. OTHER OFFICES. The Corporation may maintain offices or places of business at such other locations within or without the State of California as the Board of Directors may from time to time determine or as the business of the Corporation may require.

A member of the Board of Directors, or a member of any Committee designated by the Board of Directors shall be fully protected in relying in good faith upon the records of the Corporation and upon such information, opinions, reports or statements presented to the Corporation by any of its officers or employees, or Committees of the Board of Directors, or by any other person as to matters the Director reasonably believes are within such other person's professional or expert competence and who has been selected with reasonable care by or on behalf of the Corporation, as to the value and amount of the assets, liabilities and/or net profits of the Corporation, or any other facts pertinent to the existence and amount of surplus or other funds from which dividends might properly be declared and paid.

20

Such authorization may be general or confined to specific instances. Loans so authorized may be effected at any time for the Corporation from any bank, trust company or other institution, or from any firm, corporation or individual. All bonds, debentures, notes and other obligations or evidences of indebtedness of the Corporation issued for such loans shall be made, executed and delivered as the Board of Directors or the President shall authorize.

Section 8.05. DEPOSITS. Any funds of the Corporation may be deposited from time to time in such banks, trust companies or other depositaries as may be determined by the Board of Directors or the President, or by such officers or agents as may be authorized by the Board of Directors or the President to make such determination.

Section 8.06. CHECKS. All checks or demands for money and notes of the Corporation shall be signed by such officer or officers or such agent or agents of the Corporation, and in such manner, as the Board of Directors or the President from time to time may determine.

21

corporate seal, any instruments that may be appropriate to effect any such sale, transfer, endorsement or assignment.

Such officers acting on behalf of the Corporation shall have full power and authority to execute any instrument expressing consent to or dissent from any action of any such corporation without a meeting. The Board of Directors may by resolution from time to time confer such power and authority upon any other person or persons.

Section 8.09. FISCAL YEAR. The fiscal year of the Corporation shall commence on the first day of January of each year (except for the Corporation's first fiscal year which shall commence on the date of incorporation) and shall terminate in each case on December 31.

As adopted on April 23, 1999

ARTICLE I

SHAREHOLDERS

Section 1.01. ANNUAL MEETINGS. The annual meeting of the shareholders of the Corporation for the election of directors and for the transaction of such other business as properly may come before such meeting shall be held at such place, either within or without the State of California, and at such date and hour, as may be fixed from time to time by resolution of the Board of Directors and set forth in the notice or waiver of notice of the meeting.

Section 1.02. SPECIAL MEETINGS. Special meetings of the shareholders may be called at any time by the President (or, in the event of his absence or disability, by any Vice President), or by the Board of Directors. A special meeting shall be called by the President (or, in the event of his absence or disability, by any Vice President), or by the Secretary, immediately upon receipt of a written request therefor by shareholders holding in the aggregate not less than 10% of the outstanding shares of the Corporation at the time entitled to vote at any meeting of the shareholders. If such officers or the Board of Directors shall fail to call such meeting within 20 days after receipt of such request, any shareholder executing such request may call such meeting to be held at a time requested by the person or persons calling the meeting, not less than 35 nor more than 60 days after the receipt of the request. Such special meetings of the shareholders shall be held at such places, within or without the State of California, as shall be specified in the respective notices or waivers of notice thereof.

Section 1.03. NOTICE OF MEETINGS; WAIVER. The Secretary or any Assistant Secretary shall cause written notice of the place, date and hour of each meeting of the shareholders, and, (i) in the case of a special meeting, the general nature of the business to be transacted, or (ii) in the case of the annual meeting those matters which the Board of Directors, at the time of giving the notice, intends to present for action by the shareholders, to be given personally or by first-class mail, not less than ten nor more than sixty days prior to the meeting, to each shareholder of record entitled to vote at such meeting. The notice of any meeting at which directors are to be elected shall include the name of any nominee or nominees which, at the time of the notice, management intends to present for election.

If action is proposed to be taken at any meeting for approval of (i) a contract or transaction in which a director has a direct or indirect financial interest, pursuant to Section 310 of the Corporations Code of California, (ii) an amendment of the articles of incorporation, pursuant to Section 902 of such Code, (iii) a reorganization of the corporation, pursuant to Section 1201 of such Code, (iv) a voluntary dissolution of the corporation, pursuant to Section


1900 of such Code, or (v) a distribution in dissolution other than in accordance with the rights of outstanding preferred shares pursuant to Section 2007 of such Code, the notice shall also state the general nature of such proposal.

If such notice is mailed, it shall be deemed to have been given to a shareholder when deposited in the United States mail, postage prepaid, directed to the shareholder at his address as it appears on the record of shareholders of the Corporation, or, if he shall have filed with the Secretary of the Corporation a written request that notices to him be mailed to some other address, then directed to him at such other address. If no such address appears on the corporation's books or has been so given, notice shall be deemed to have been given if sent by first-class mail or telegraphic or other written communication to the corporation's principal executive office, or if published at least once in a newspaper of general circulation in the county where such office is located.

If any notice addressed to a shareholder at the address of such shareholder appearing on the books of the corporation is returned to the corporation by the United States Postal Service marked to indicate that the United States Postal Service is unable to deliver the notice to the shareholder at such address, all future notices or reports shall be deemed to have been duly given without further mailing if the same shall be available to the shareholder upon written demand of the shareholder at the principal executive office of the corporation for a period of one year from the date of the giving of such notice. Such further notice shall be given as may be required by law.

No notice of any meeting of shareholders need be given to any shareholder who submits a signed waiver of notice, whether before or after the meeting. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the shareholders need be specified in a written waiver of notice. The attendance of any shareholder at a meeting of shareholders shall constitute a waiver of notice of such meeting, except when the shareholder attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business on the ground that the meeting is not lawfully called or convened.

An affidavit of the mailing or other means of giving any notice of any shareholders' meeting shall be executed by the Secretary, Assistant Secretary or any transfer agent of the corporation giving such notice, and shall be filed and maintained in the minute book of the corporation.

Section 1.04. QUORUM. Except as otherwise required by law or by the Certificate of Incorporation, the presence in person or by proxy of the holders of record of a majority of the shares entitled to vote at a meeting of shareholders shall constitute a quorum for the transaction of business at such meeting.

Section 1.05. VOTING. If, pursuant to Section 5.05 of these By-Laws, a record date has been fixed, every holder of record of shares entitled to vote at a meeting of shareholders

2

shall be entitled to one vote for each share outstanding in his name on the books of the Corporation at the close of business on such record date. If no record date has been fixed, then every holder of record of shares entitled to vote at a meeting of shareholders shall be entitled to one vote for each share of stock standing in his name on the books of the Corporation at the close of business on the day next preceding the day on which notice of the meeting is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held.

Any shareholder entitled to vote on any matter (other than the election of directors) may vote part of the shares in favor of the proposal and refrain from voting the remaining shares or vote them against the proposal, but, if the shareholder fails to specify the number of shares such shareholder is voting affirmatively, it will be conclusively presumed that the shareholder's approving vote is with respect to all shares such shareholder is entitled to vote. If a quorum is present, the affirmative vote of the majority of the shares represented at the meeting and voting on any matter (other than the election of directors), provided that the shares voting affirmatively must also constitute at least a majority of the required quorum, shall be the act of the shareholders, unless the vote of a greater number or voting by classes is required by the California General Corporation Law or the articles of incorporation.

At a shareholders' meeting involving the election of directors, no shareholder shall be entitled to cumulate votes (i.e., cast for any candidate a number of votes greater than the number of the shareholder's shares) unless such candidate or candidates' names have been placed in nomination prior to commencement of the voting and a shareholder has given notice prior to commencement of the voting of the shareholder's intention to cumulate votes. If any shareholder has given such notice, then every shareholder entitled to vote may cumulate such shareholder's votes for candidates in nomination and give one candidate a number of votes equal to the number of directors to be elected multiplied by the number of votes to which such shareholder's shares are entitled, or distribute the shareholder's votes on the same principle among any or all of the candidates, as the shareholder thinks fit. The candidates receiving the highest number of votes, up to the number of directors to be elected, shall be elected.

Section 1.06. VOTING BY BALLOT. No vote of the shareholders need be taken by ballot unless required by law (except that all elections for directors must be by ballot upon demand by a shareholder at the meeting and before the voting begins). Any vote which need not be taken by ballot may be conducted by voice vote or in any manner approved by the meeting.

Section 1.07. ADJOURNMENT. If a quorum is not present at any meeting of the shareholders, the shareholders present in person or by proxy shall have the power to adjourn any such meeting from time to time until a quorum is present. Notice of any adjourned meeting of the shareholders of the Corporation need not be given if the place, date and hour thereof are announced at the meeting at which the adjournment is taken, provided, however, that if the adjournment is for more than thirty days, or if after the adjournment a new record date for the adjourned meeting is fixed pursuant to Section 5.05 of these By-Laws, a notice of the adjourned

3

meeting, conforming to the requirements of Section 1.03 hereof, shall be given to each shareholder of record entitled to vote at such meeting. At any adjourned meeting at which a quorum is present, any business may be transacted that might have been transacted on the original date of the meeting.

Section 1.08. PROXIES. Any shareholder entitled to vote at any meeting of the shareholders or to express consent to or dissent from corporate action without a meeting may authorize another person or persons to vote at any such meeting and express such consent or dissent for him by proxy. A shareholder may authorize a valid proxy by executing a written instrument signed by such shareholder, or by causing his or her signature to be affixed to such writing by any reasonable means including, but not limited to, by facsimile signature, or by transmitting or authorizing the transmission of a telegram, cablegram or other means of electronic transmission to the person designated as the holder of the proxy, a proxy solicitation firm or a like authorized agent. A proxy must be filed with the Secretary of the corporation. No such proxy shall be voted or acted upon after the expiration of eleven months from the date of such proxy, unless such proxy provides for a longer period. Every proxy shall be revocable at the pleasure of the shareholder executing it, except in those cases where applicable law provides that a proxy shall be irrevocable. A shareholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by filing an instrument in writing revoking the proxy or by filing another duly executed proxy bearing a later date with the Secretary. Proxies by telegram, cablegram or other electronic transmission must either set forth or be submitted with information from which it can be determined that the telegram, cablegram or other electronic transmission was authorized by the shareholder. Any copy, facsimile telecommunication or other reliable reproduction of a writing or transmission created pursuant to this section may be substituted or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission.

Section 1.09. ORGANIZATION; PROCEDURE. At every meeting of shareholders the presiding officer shall be the President or, in the event of his absence or disability, a presiding officer chosen by a majority of the shareholders present in person or by proxy. The Secretary, or in the event of his absence or disability, the Assistant Secretary, if any, or if there be no Assistant Secretary, in the absence of the Secretary, an appointee of the presiding officer, shall act as Secretary of the meeting. The order of business and all other matters of procedure at every meeting of shareholders may be determined by such presiding officer.

Section 1.10. CONSENT OF SHAREHOLDERS IN LIEU OF MEETING. To the fullest extent permitted by law, whenever the vote of shareholders at a meeting thereof is required or permitted to be taken for or in connection with any corporate action, such action may be taken without a meeting, without prior notice and without a vote of shareholders, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take

4

such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be filed with the Secretary of the corporation and shall be maintained in the corporate records. In the case of election of directors, such consent shall be effective only if signed by the holders of all outstanding shares entitled to vote for the election of directors; provided, however, that a director may be elected at any time to fill a vacancy not created by removal and not filled by the directors by the written consent of the holders of a majority of the outstanding shares entitled to vote for the election of directors.

Every written consent shall bear the date of signature of each shareholder or member who signs the consent and no written consent shall be effective to take the corporate action referred to therein unless, within sixty days of the earliest dated consent delivered in the manner required by law to the Corporation, written consents signed by a sufficient number of holders or members to take action are delivered to the Corporation. Any shareholder giving a written consent, or the shareholder's proxy holders, or a transferee of the shares or a personal representative of the shareholder or their respective proxy holder, may revoke the consent by a writing received by the Secretary of the corporation prior to the time that written consents of the number of shares required to authorize the proposed action have been filed with the Secretary.

The Board of Directors may require the owner of such lost, stolen or destroyed certificate, or his legal representative, to give the Corporation a bond sufficient to indemnify it against any claim that may be made against it on account of the alleged loss, theft or destruction of any such certificate or the issuance of any such new certificate.

A determination of shareholders of record entitled to notice of or to vote at a meeting of shareholders shall apply to any adjournment of the meeting, provided, however, that the Board of Directors may fix a new record date for the adjourned meeting. If no record date has been fixed by the Board of Directors, the record date for determining shareholders entitled to notice of or to vote at a meeting of shareholders shall be at the close of business on the business day next preceding the day on which notice if given or, if notice is waived, at the close of business on the business day next preceding the day on which the meeting is held.

In order that the Corporation may determine the shareholders entitled to consent to corporate action in writing without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than ten days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. If no record date has been fixed by the Board of Directors, the record date for determining shareholders entitled to consent to corporate action in writing without a meeting, (i) when no prior action by the Board has been taken, shall be the day on which the first written consent is given, or (ii) when prior action of the

15

Board has been taken, shall be at the close of business on the day on which the Board adopts the resolution relating thereto, or the sixtieth
(60th) day prior to the date of such other action, whichever is later.

In order that the Corporation may determine the shareholders entitled to receive payment of any dividend or other distribution or allotment of any rights of the shareholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purpose of any other lawful action (other than action by shareholders by written consent without a meeting), the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than sixty days prior to such action. If no record date is fixed, the record date for determining shareholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto, (i) when no prior action by the Board has been taken, shall be the day on which the first written consent is given, or
(ii) when prior action of the Board has been taken, shall be at the close of business on the day on which the Board adopts the resolution relating thereto, or the sixtieth (60th) day prior to the date of such other action, whichever is later.

Section 5.06. REGISTERED SHAREHOLDERS. Prior to due surrender of a certificate for registration of transfer, the Corporation may treat the registered owner as the person exclusively entitled to receive dividends and other distributions, to vote, to receive notice and otherwise to exercise all the rights and powers of the owner of the shares represented by such certificate, and the Corporation shall not be bound to recognize any equitable or legal claim to or interest in such shares on the part of any other person, whether or not the Corporation shall have notice of such claim or interests. Whenever any transfer of shares shall be made for collateral security, and not absolutely, it shall be so expressed in the entry of the transfer if, when the certificates are presented to the Corporation for transfer or uncertificated shares are requested to be transferred, both the transferor and transferee request the Corporation to do so.

Section 5.07. TRANSFER AGENT AND REGISTRAR. The Board of Directors may appoint one or more transfer agents and one or more registrars, and may require all certificates representing shares to bear the signature of any such transfer agents or registrars.

ARTICLE VI

INDEMNIFICATION

Section 6.01. NATURE OF INDEMNITY. The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was or has agreed to become a director or officer of the Corporation, or is or was serving or has agreed to serve at the request of the Corporation as a director or officer, of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any

16

action alleged to have been taken or omitted in such capacity, and may indemnify any person who was or is a party or is threatened to be made a party to such an action, suit or proceeding by reason of the fact that he is or was or has agreed to become an employee or agent of the Corporation, or is or was serving or has agreed to serve at the request of the Corporation as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees) , judgments, fines and amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with such action, suit or proceeding and any appeal therefrom, if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding had no reasonable cause to believe his conduct was unlawful; except that in the case of an action or suit by or in the right of the Corporation to procure a judgment in its favor (1) such indemnification shall be limited to expenses (including attorneys' fees) actually and reasonably incurred by such person in the defense or settlement of such action or suit, and (2) no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

The termination of any action, suit or proceeding by judgment, order settlement, conviction, or upon a plea of NOLO CONTENDERE or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

Section 6.02. SUCCESSFUL DEFENSE. To the extent that a director, officer, employee or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section 6.01 hereof or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith.

Section 6.03. DETERMINATION THAT INDEMNIFICATION IS PROPER. Any indemnification of a director or officer of the Corporation under Section 6.01 hereof (unless ordered by a court) shall be made by the Corporation unless a determination is made that indemnification of the director or officer is not proper in the circumstances because he has not met the applicable standard of conduct set forth in Section 6.01 hereof. Any indemnification of an employee or agent of the Corporation under Section 6.01 hereof (unless ordered by a court) may be made by the Corporation upon a determination that indemnification of the employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Section 6.01 hereof. Any such determination shall be made:

(1) by the Board of Directors by a majority vote of a quorum consisting of

17

directors who were not parties to such action, suit or proceeding, or

(2) if such a quorum is not obtainable, or, even if obtainable a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or

(3) by the shareholders, with the shares owned by the person to be indemnified not being entitled to vote thereon, or

(4) by the court in which the proceeding is or was pending upon application made by the corporation or the agent or the attorney or other person rendering services in connection with the defense, whether or not the application by the agent, attorney or other person is opposed by the corporation.

Section 6.04. ADVANCE PAYMENT OF EXPENSES. Expenses (including attorneys' fees) incurred by a director or officer in defending any civil, criminal, administrative or investigative action, suit or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation as authorized in this Article. Such expenses (including attorneys' fees) incurred by other employees and agents may be so paid upon such terms and conditions, if any, as the Board of Directors deems appropriate. The Board of Directors may authorize the Corporation's counsel to represent such director, officer, employee or agent in any action, suit or proceeding, whether or not the Corporation is a party to such action, suit or proceeding.

No indemnification or advance shall be made under this section, except as provided in Section 6.02 or paragraph (4) of Section 6.03, in any circumstance where it appears: (1) that it would be inconsistent with a provision of the articles, bylaws, a resolution of the shareholders, or an agreement in effect at the time of the accrual of the alleged cause of action asserted in the proceeding in which the expenses were incurred or other amounts were paid, which prohibits or otherwise limits indemnification or (2) that it would be inconsistent with any condition expressly imposed by a court in approving a settlement.

Section 6.05. PROCEDURE FOR INDEMNIFICATION OF DIRECTORS AND OFFICERS. Any indemnification of a director or officer of the Corporation under Sections 6.01 and 6.02, or advance of costs, charges and expenses to a director or officer under Section 6.04 of this Article, shall be made promptly, and in any event within 30 days, upon the written request of the director or officer. If a determination by the Corporation that the director or officer is entitled to indemnification pursuant to this Article is required, and the Corporation fails to respond within sixty days to a written request for indemnity, the Corporation shall be deemed to have approved such request. If the Corporation denies a written request for indemnity or advancement of expenses, in whole or in part, or if payment in full pursuant to such request is not made within 30 days, the right to indemnification or advances as granted by this Article shall be enforceable by

18

the director or officer in any court of competent jurisdiction. Such person's costs and expenses incurred in connection with successfully establishing his right to indemnification, in whole or in part, in any such action shall also be indemnified by the Corporation. It shall be a defense to any such action (other than an action brought to enforce a claim for the advance of costs, charges and expenses under Section 6.04 of this Article where the required undertaking, if any, has been received by the Corporation) that the claimant has not met the standard of conduct set forth in Section 6.01 of this Article, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, its independent legal counsel, and its shareholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he has met the applicable standard of conduct set forth in Section 6.01 of this Article, nor the fact that there has been an actual determination by the Corporation (including its Board of Directors, its independent legal counsel, and its shareholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

Section 6.06. SURVIVAL; PRESERVATION OF OTHER RIGHTS. The foregoing indemnification provisions shall be deemed to be a contract between the Corporation and each director, officer, employee and agent who serves in any such capacity at any time while these provisions as well as the relevant provisions of the California Corporation Law are in effect and any repeal or modification thereof shall not affect any right or obligation then existing with respect to any state of facts then or previously existing or any action, suit or proceeding previously or thereafter brought or threatened based in whole or in part upon any such state of facts. Such a "contract right" may not be modified retroactively without the consent of such director, officer, employee or agent.

The indemnification provided by this Article VI shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any by-law, agreement, vote of shareholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

Section 6.07. INSURANCE. The Corporation shall purchase and maintain insurance on behalf of any person who is or was or has agreed to become a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him or on his behalf in any such capacity, or arising out of his status as such, whether or not the Corporation would have the power to indemnify him against such liability under the provisions of this Article, PROVIDED that such insurance is available on acceptable terms, which determination shall be made by a vote of a majority of the entire Board of Directors.

19

Section 6.08. SEVERABILITY. If this Article or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each director or officer and may indemnify each employee or agent of the Corporation as to costs, charges and expenses (including attorneys' fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative, including an action by or in the right of the Corporation, to the fullest extent permitted by any applicable portion of this Article that shall not have been invalidated and to the fullest extent permitted by applicable law.

ARTICLE VII

OFFICES

Section 7.01. PRINCIPAL OFFICES. The Board of Directors shall fix the location of the principal executive office of the corporation at any place within or outside the State of California. If the principal executive office is located outside this state, and the corporation has one or more business offices in this state, the Board of Directors shall likewise fix and designate a principal business office in the State of California.

Exhibit 4.2

SUPPLEMENTAL INDENTURE

SUPPLEMENTAL INDENTURE (this "SUPPLEMENTAL INDENTURE"), dated as of April 23, 1999 among Adams Rite Aerospace, Inc. a California corporation, ZMP, Inc. a California corporation (collectively, the "GUARANTEEING SUBSIDIARIES," and, each a "GUARANTEEING SUBSIDIARY"), each a subsidiary of TransDigm Inc., a Delaware corporation (the "COMPANY"), the Company, TransDigm Holding Company, a Delaware corporation ("HOLDINGS") and Marathon Power Technologies Company, a Delaware corporation ("MARATHON" and together with Holdings and the Guaranteeing Subsidiaries, the "GUARANTORS") and State Street Bank and Trust Company, as trustee under the indenture referred to below (the "TRUSTEE").

W I T N E S S E T H

WHEREAS, the Company, Holdings and Marathon have heretofore executed and delivered to the Trustee an indenture (the "INDENTURE"), dated as of December 3, 1998 providing for the issuance of an aggregate principal amount of up to $200.0 million of 10 3/8% Senior Subordinated Notes due 2008 (the "Notes") and the guarantees thereof by Holdings and Marathon;

WHEREAS, the Indenture provides that under certain circumstances newly acquired Subsidiaries of the Company shall execute and deliver to the Trustee a supplemental indenture pursuant to which such Subsidiaries shall unconditionally guarantee all of the Company's Obligations under the Notes and the Indenture on the terms and conditions set forth therein (the "GUARANTEE"); and

WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, each Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the indenture.

2. AGREEMENT TO GUARANTEE. Each Guaranteeing Subsidiary hereby agrees as follows:

(a) Along with all Guarantors named in the Indenture, to jointly and severally Guarantee to each Holder of a Note authenticated and delivered by the

1

Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

(i) the principal of and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately.

(b) The obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

(c) The following is hereby waived: diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever.

(d) This Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and the Indenture or pursuant to Section 6 hereof.

(e) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, or any custodian, Trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

2

(f) Each Guaranteeing Subsidiary shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby.

(g) As between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 of the Indenture for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 6 of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Guarantee.

(h) The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Guarantee.

(i) Pursuant to Section 11.03 of the Indenture, after giving effect to any maximum amount and any other contingent and fixed liabilities that are relevant under any applicable Bankruptcy or fraudulent conveyance laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under Article 11 of the Indenture, the obligations of each Guaranteeing Subsidiary shall be limited to the maximum amount as will result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent transfer or conveyance.

3. SUBORDINATION. The obligations of each Guaranteeing Subsidiary under its guarantee pursuant to this Supplemental Indenture shall be junior and subordinated to the Senior Debt of each such Guaranteeing Subsidiary on the same basis as the Notes are junior and subordinated to the Senior Debt of the Company. For the purposes of the foregoing sentence, the Trustee and the Holders shall have the right to receive and/or retain payments by each Guaranteeing Subsidiary only at such time as they may receive and/or retain payments in respect of the notes pursuant to the indenture, including article 10 thereof.

4. EXECUTION AND DELIVERY. Each guaranteeing subsidiary agrees that the guarantees shall remain in full force and effect notwithstanding any failure to endorse on each note a notation of such guarantee.

5. GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS. Each Guaranteeing Subsidiary will be subject to Section 11.05 of the Indenture.

6. RELEASES. In the event of a sale or other disposition of all of the assets of any guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all to the

3

capital stock of any Guarantor, then such guarantor (in the event of a sale or other disposition, by way of merger, consolidation or otherwise, of all of the capital stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor) will be released and relieved of any obligations under its Guarantee; PROVIDED that the net proceeds of such sale or other disposition are applied in accordance with the applicable provisions of the Indenture, including without limitation section 4.10 of the Indenture. Upon delivery by the Company to the Trustee of an Officers' Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in accordance with the provisions of the indenture, including without limitation
Section 4.10 of the Indenture, the Trustee shall execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Guarantee.

(a) Any Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of and interest on the and for the other obligations of any guarantor under the indenture as provided in Article 10 of the indenture.

7. NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, employee, incorporator, stockholder or agent of either Guaranteeing Subsidiary, as such, shall have any liability for any obligations of the Company or any Guaranteeing Subsidiary under the Notes, any Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Commission that such a waiver is against public policy.

8. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

9. COUNTERPARTS The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

10. EFFECT OF HEADINGS. The Section headings herein are for convenience only and shall not affect the construction hereof.

11. THE TRUSTEE. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiaries and the Company.

4

IN WITNESS WHEREOF, the parties hereto have caused this Supplemental Indenture to be duly executed and attested, all as of the date first above written.

SECOND AMENDMENT TO CREDIT AGREEMENT (this "Amendment"), dated as of April 23, 1999, among TRANSDIGM HOLDING COMPANY, a Delaware corporation ("Holdings"), TRANSDIGM INC., a Delaware corporation (the "Borrower"), the various lending institutions party to the Credit Agreement referred to below (each, a "Lender" and, collectively, the "Lenders"), and BANKERS TRUST COMPANY, as Administrative Agent for the Lenders (the "Administrative Agent"). All capitalized terms used herein and not otherwise defined herein shall have the meanings provided such terms in the Credit Agreement.

W I T N E S S E T H :

WHEREAS, Holdings, the Borrower, the Lenders and the Administrative Agent are parties to a Credit Agreement, dated as of December 3, 1998 (as amended through, but not including, the date hereof, the "Credit Agreement"); and

WHEREAS, the parties hereto wish to amend the Credit Agreement as herein provided;

NOW, THEREFORE, it is agreed:

I. AMENDMENTS TO CREDIT AGREEMENT.

1. Section 1.01 of the Credit Agreement is hereby amended by deleting clause (a) thereof in its entirety and inserting the following new clause (a) in lieu thereof:

"(a) Subject to and upon the terms and conditions set forth herein, (A) each Lender with an A Term Loan Commitment on the Initial Borrowing Date severally agrees to make on such date, and (B) each Lender with an A Term Loan Commitment on the AR Acquisition Date severally agrees to make on such date, in each case, a term loan (each, an "A Term Loan" and, collectively, the "A Term Loans") to the Borrower, which A Term Loans: (i) shall be incurred pursuant to two single drawings, the first of which shall be on the Initial Borrowing Date and the second of which shall be on the AR Acquisition Date; (ii) shall be denominated in U.S. Dollars; (iii) except as hereafter provided, shall, at the option of the Borrower, be incurred and maintained as, and/or converted into, Base Rate Loans or Eurodollar Loans, provided that (x) all A Term Loans made as part of the same Borrowing shall, unless otherwise specifically provided herein, consist of A Term Loans of the same Type and (y) unless the Administrative Agent has determined that the Syndication Date has occurred (at which time this clause (y) shall no longer be applicable), no more than four Borrowings of A Term Loans to be maintained as Eurodollar Loans may be incurred prior to the 60th day after the Initial Borrowing Date (each of which Borrowings of Eurodollar Loans may only have an Interest Period of (A) in the case of the first two such Borrowings, seven days, and (B) in the case of the remaining two Borrowings, one month, and the first of which Borrowings may only be made on the Initial Borrowing Date or on or prior to the sixth Business Day after the


Initial Borrowing Date and with each such Borrowing made thereafter to be made only on the last day of the Interest Period of the immediately preceding Borrowing); and (iv) shall not exceed for any such Lender at the time of incurrence thereof on the Initial Borrowing Date or the AR Acquisition Date, as the case may be, that aggregate principal amount as is equal to the A Term Loan Commitment of such Lender as in effect on the Initial Borrowing Date or the AR Acquisition Date, as the case may be (before giving effect to any reductions thereto on such respective date pursuant to Section 3.03(b)).

(ii) (x) there shall have been delivered to the Administrative Agent and the Lenders true and correct copies of all AR Transaction Documents, certified as such by an Authorized Officer of Holdings or the Borrower, and all terms and conditions of the AR Transaction Documents shall be in form and substance reasonably satisfactory to the Administrative Agent, and (y) the AR Transaction shall have been consummated in accordance with the AR Transaction Documents (without giving effect to any amendment or modification thereof or waiver with respect thereto unless consented to by the Administrative Agent) and the relevant requirements of the Credit Agreement (as amended hereby);

Notwithstanding anything to the contrary contained above or elsewhere in this Second Amendment, unless both the Second Amendment Effective Date and the AR Acquisition Date occur on or prior to March 31, 1999, the Second Amendment Effective Date shall not thereafter occur and this Amendment shall be of no further force or effect. Unless the Administrative Agent has received actual notice from any Lender that the conditions contained above have not been met, upon the satisfaction of the condition described in clause (i) of the immediately preceding sentence and upon the Administrative Agent's good faith determination that the other conditions described above have been met, the Second Amendment Effective Date shall be deemed to have occurred, regardless of any subsequent determination that one or more of the conditions thereto had not been met (although the occurrence of the Second Amendment Effective Date shall not release the Borrower from any liability for failure to satisfy one or more of the applicable conditions specified above). The Administrative Agent will give the Borrower and each Lender prompt notice of the occurrence of the Second Amendment Effective Date. The acceptance by the Borrower of the proceeds of the Loans on the AR Acquisition Date shall be deemed to constitute a representation and warranty by the Borrower (including, without limitation, for purposes of
Section 10.02 of the Credit Agreement) to the effect that all conditions contained above in this Paragraph 6 have been satisfied as of the Second Amendment Effective Date.

7. From and after the Second Amendment Effective Date, all references in the Credit Agreement and each of the other Credit Documents to the Credit Agreement shall be deemed to be references to the Credit Agreement as amended hereby.

(D) 2.50% if, but only if, as of the Test Date for such Start Date the Total Leverage Ratio for the Test Period ended on such Test Date shall be less than 2.50:1.00.

Notwithstanding anything to the contrary contained above in this clause
(a), (x) each of the percentages set forth above in this definition which would otherwise be in effect for any Applicable Margin Period shall be reduced by .25% from and after the respective Start Date to and including the corresponding End Date for such Applicable Margin Period if, but only if, as of the Test Date for such Start Date both the Senior Leverage Ratio for the Test Period ended on such Test Date shall be less than 2.75:1.00 and the Consolidated Interest Coverage Ratio for such Test Period shall be greater than 1.80:1.00 and (y) the Applicable Eurodollar Rate Margin for A Term Loans and Revolving Loans maintained as Eurodollar Loans shall be 3.25% at all times when a Default or an Event of Default shall exist; and

(b) in the case of B Term Loans maintained as Eurodollar Loans, 3.50%.

II. MISCELLANEOUS PROVISIONS.

1. In order to induce the Lenders to enter into this Amendment, each of Holdings and the Borrower hereby represents and warrants that:

(a) no Default or Event of Default exists as of the Third Amendment Effective Date (as defined below), both before and after giving effect to this Amendment; and

(b) all of the representations and warranties contained in the Credit Agreement and the other Credit Documents are true and correct in all material respects on the Third Amendment Effective Date, both before and after giving effect to this Amendment, with the same effect as though such representations and warranties had been made on and as of the Third Amendment Effective Date (it being understood that any representation or warranty made as of a specific date shall be true and correct in all material respects as of such specific date).

2. This Amendment is limited as specified and shall not constitute a modification, acceptance or waiver of any other provision of the Credit Agreement or any other Credit Document.

3. This Amendment may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which counterparts when executed and delivered shall be an original, but all of which shall together constitute one and the same instrument. A complete set of counterparts shall be lodged with the Borrower and the Administrative Agent.

4. THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HERETO SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK.

5. This Amendment shall become effective on the date (the "Third Amendment Effective Date") when each of Holdings, the Borrower and each Lender shall have signed a counterpart hereof (whether the same or different counterparts) and shall have delivered (including by way of facsimile transmission) the same to the Administrative Agent at the Notice Office.

6. From and after the Third Amendment Effective Date, all references in the Credit Agreement and each of the other Credit Documents to the Credit Agreement shall be deemed to be references to the Credit Agreement as amended hereby.

In our capacity as your special counsel, we are familiar with the proceedings taken and proposed to be taken by the Company and the Guarantors in connection with the authorization and issuance of the New Notes and the New Guarantees, respectively, and for the purposes of this opinion, have assumed such proceedings will be timely completed in the manner currently proposed. In addition, we have made such legal and factual examinations and inquiries, including an examination of originals or copies certified or otherwise identified to our satisfaction of such documents, corporate records and instruments, as we have deemed necessary or appropriate for purposes of this opinion.

In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all documents submitted to us as copies. As to facts material to the opinions, statements and assumptions expressed herein, we have, with your consent, relied upon oral or written statements and representations of officers and other representatives of the Company, the Guarantors and others.

We are opining herein as to the effect on the subject transaction only of the federal laws of the United States, the internal laws of the States of New York and California and the General Corporation Law of the State of Delaware, and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or, in the case of

Delaware, any other laws, or as to any matters of municipal law or the laws of any other local agencies within any state.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof:

(1) The New Notes to be exchanged for the Old Notes pursuant to the Exchange Offer have been duly authorized by all necessary corporate action on the part of the Company, and, when duly executed, issued and authenticated in accordance with the terms of the Exchange Offer and the Indenture and exchanged for the Old Notes in accordance with the terms of the Exchange Offer, will be the legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

(2) Each of the New Guarantees has been duly authorized by all necessary corporate action on the part of the Guarantors, and, when duly executed and endorsed on the New Notes in accordance with the terms of the Indenture and upon the due execution, issuance and authentication of the New Notes in accordance with the terms of the Exchange Offer and the Indenture and exchange of the New Notes for the Old Notes in accordance with the terms of the Exchange Offer, will be the legally valid and binding obligation of each of the Guarantors, enforceable against each of the Guarantors in accordance with its terms.

The opinions rendered in paragraphs 1 and 2 relating to the enforceability of the New Notes and the New Guarantees are subject to the following exceptions, limitations and qualifications: (i) the effect of bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights and remedies of creditors; (ii) the effect of general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought and (iii) we express no opinion concerning the enforceability of the waiver of rights or defenses contained in Section 4.06 of the Indenture.

To the extent that the obligations of the Company or any of the Guarantors under the Indenture, the New Notes or the New Guarantees may be dependent upon such matters, we have assumed for purposes of this opinion that
(i) the Trustee (a) is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization; (b) has the requisite organizational and legal power and authority to perform its obligations under the Indenture; (c) is duly qualified to engage in the activities contemplated by the Indenture; (d) has duly authorized, executed and delivered the Indenture and
(e) has complied with any applicable requirement to file returns and pay taxes under the Franchise Tax Law of the State of California; (ii) the Indenture is the legally valid and binding agreement of the Trustee, enforceable against

the Trustee in accordance with its terms; and (iii) that the Trustee is in compliance, generally and with respect to acting as Trustee under the Indenture, with all applicable laws and regulations. We have also assumed, with your consent, that the choice of law provisions in the Indenture would be enforced by any court in which enforcement thereof might be sought.

We have not been requested to express and, with your knowledge and consent, do not render any opinion as to the applicability to the obligations of the Company and the Guarantors under the Indenture, the New Notes and the New Guarantees, as applicable, of Sections 547 and 548 of the Bankruptcy Code or applicable state law (including, without limitation, Article 10 of the New York Debtor & Creditor Law) relating to preferences and fraudulent transfers and obligations.

We consent to your filing this opinion as an exhibit to the Registration Statement and to the reference to our firm contained under the heading "Legal Matters."

Very truly yours,
