Item 2. Acquisition or Disposition of Assets.

On February 8, 1999, Olin Corporation ("Olin") distributed to its common shareholders one share of Arch Chemicals, Inc. ("Arch Chemicals") Common Stock, par value $1 per share, for each two shares of Olin Common Stock held of record as of the close of business on February 1, 1999, (the "Distribution"). Olin also transferred to Arch Chemicals all of the specialty chemicals businesses formerly conducted by Olin. The Distribution was consummated pursuant to the terms of a Distribution Agreement dated as of February 1, 1999 by and between Olin and Arch Chemicals, a copy of which is filed as an exhibit hereto.

Item 7. Financial Statement and Exhibits.

(b) Pro Forma Financial Information

Spin-off of Arch Chemicals

As noted above, on February 8, 1999, Olin distributed its specialty chemicals businesses to its shareholders as a separate public company, Arch Chemicals. Holders of Olin Common Stock of record on February 1, 1999 received one share of Arch Chemicals Common Stock for every two shares of Olin Common Stock held.

Pro Forma

The following unaudited pro forma condensed consolidated information is based on the historical consolidated financial statements of Olin adjusted to give effect to the Distribution.

The unaudited pro forma condensed consolidated balance sheet as of September 30, 1998 gives effect to the elimination of the specialty chemicals businesses, as well as other adjustments, assuming the Distribution had taken place on September 30, 1998.

The unaudited pro forma condensed consolidated income statements for the year ended December 31, 1997 and the nine months ended September 30, 1998 give effect to the elimination of the specialty chemicals businesses as well as other adjustments, assuming the Distribution had taken place as of the beginning of each of those periods.

The pro forma adjustments are based upon available information and certain assumptions that management believes are reasonable.

The following unaudited pro forma condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission. Management does not believe that this pro forma presentation is indicative of the financial position and results which would have occurred had the transactions occurred on the dates indicated in the pro forma condensed consolidated financial statements because of the hypothetical nature of the pro forma information and because Olin may have operated its other remaining businesses differently during those periods.

Notes to Pro Forma Condensed Consolidated Income Statement For the Nine Months Ended September 30, 1998 and Year Ended December 31, 1997

(Unaudited)

The preceding pro forma income statements present the consolidated income of Olin for the nine months ended September 30, 1998 and the year ended December 31, 1997 after eliminating the specialty chemicals businesses and after giving effect to the adjustment described below.

The adjustment made to these pro forma income statements assumes that the Distribution occurred as of the beginning of each period.

It is management's opinion that these pro forma results are not necessarily indicative of the results which would have occurred had the Distribution been made at the beginning of each of those periods.

Historically Reported

The historically reported column represents the historical consolidated income of Olin for the nine months ended September 30, 1998 and year ended December 31, 1997, respectively.

Divestment

The divestments represent the historical results of the specialty chemicals businesses for the nine months ended September 30, 1998 and the year ended December 31, 1997, respectively.

Prior to the Distribution, Arch Chemicals succeeded to a $250 million credit facility ("Credit Facility") established by Olin. Prior to the Distribution, Olin borrowed $75 million under the Credit Facility, which liability was assumed by Arch Chemicals. Olin intends to use the proceeds for general corporate purposes, which may include share repurchases and future acquisitions. An assessment of corporate overhead is included in selling and administration expenses with the allocation based on either effort committed or number of employees. Management believes that the allocation methods used to allocate the costs and expenses are reasonable, however, such allocated amounts may or may not necessarily be indicative of what selling and administration expenses would have been if Arch Chemicals had operated independently of Olin. Income taxes have been calculated based on Arch Chemicals' allocated share of Olin's consolidated income tax provision and are calculated on a separate company basis pursuant to the requirements of Statement of Financial Accounting Standards No. 109 "Accounting for Income Taxes".

This transaction was a tax free spin-off, and accordingly, no gain or loss was recorded by Olin.

Pro Forma Adjustments

(a) This adjustment records the sales from Olin's Chlor-Alkali division to Arch Chemicals which had been eliminated in the historical consolidated income statements as they were considered inter-company sales. This adjustment reflects the pro forma impact of the chloric supply agreement between Olin and Arch Chemicals entered into at the time of the distribution. Proforma adjustments exclude spin-off costs of $21 million pretax which were recorded in the fourth quarter of 1998.

Each of Olin and its Subsidiaries and Arch and its Subsidiaries shall not use or permit the use of (without the prior written consent of the other) and shall hold, and shall cause its consultants and advisors to hold, in strict confidence, all information concerning the other parties in its possession, its custody or under its control (except to the extent that (A) such information has been in the public domain or becomes part of the public domain through no fault of such party, (B) such information has been later lawfully acquired from other sources by such party without an obligation of confidence, (C) this Agreement or any other Ancillary Agreement or any other agreement entered into pursuant hereto permits the use or disclosure of such information, (D) such information is requested by the Commission (i) to be provided supple mentally to the Commission or (ii) to be provided in any document filed with the Commission, provided, that in the case of this clause (ii), the party providing such informa tion to the Commission shall first consult with the other party prior to, but shall not be prohibited from making, such disclosure or (E) such information is independently developed by such party without reference to such informa tion) to the extent such information (x) relates to the period up to the Distribution Date, (y) relates to any Ancillary Agreement or (z) is obtained in the course of performing services for the other party pursuant to any Ancillary Agreement, and each party shall not (without the prior written consent of the other) otherwise release or disclose such information to any other person, except such party's auditors and attorneys, unless compelled to disclose such information by judicial or administrative process or unless such disclosure is required by law and such party has used commercially reasonable efforts to consult with the other affected party or parties prior to such disclosure. To the extent that a party hereto is compelled by judicial or administrative process to disclose such information under circumstances in which any evidentiary privilege would be available, such party agrees to assert such privilege in good faith prior to making such disclosure. Each party hereto agrees to consult with the other party in connection with any such judicial or administrative process, including in determining whether any privilege is available, and further agrees to allow such party and its counsel to participate in any hearing or other proceeding (including any appeal of an initial order to disclose) in respect of such disclosure and assertion of privilege. Each of Olin


and Arch intends that the transactions contemplated hereby and by the Ancillary Agreements and any transfer of information in connection therewith shall not operate as a waiver of any potentially applicable privilege.

ARTICLE V

Dispute Resolution

SECTION 5.01. Dispute Resolution. (a) In the event of a controversy, dispute or claim arising out of, in connection with, or in relation to the interpretation, performance, nonperformance, validity or breach of this Agreement or otherwise arising out of, or in any way related to this Agreement, including any claim based on contract, tort, statute or constitution (collectively, "Agreement Disputes"), the General Counsels (or their designees) of the relevant parties shall negotiate, commencing within 30 days of the occurrence of such Agreement Dispute, in good faith for a reasonable period of time to settle such Agreement Dispute.

(b) If after such reasonable period such General Counsels (or their designees) are unable to settle such Agreement Dispute (and in any event after 60 days have elapsed from the time the relevant parties began such negotiations), such Agreement Dispute shall be determined, at the request of any relevant party, by arbitration conducted in New York City, before and in accordance with the then-existing Rules for Commercial Arbitration of the American Arbitration Association (the "Rules"), and any judgment or award rendered by the arbitrator shall be final, binding and nonappealable (except upon grounds specified in 9 U.S.C. ss.10(a) as in effect on the date hereof), and judg ment may be entered by any state or Federal court having jurisdiction thereof in accordance with Section 8.21 hereof. Unless the arbitrator otherwise determines, the pre-trial discovery of the then-existing Federal Rules of Civil Procedure and the then-existing Rules 46 and 47 of the Civil Rules for the United States District Court for the Southern District of New York shall apply to any arbitration here under. Any controversy concerning whether an Agreement Dispute is an arbitrable Agreement Dispute, whether arbitra tion has been waived, whether an assignee of this Agreement is bound to arbitrate, or as to the interpretation of enforceability of this Article V shall be determined by the arbitrator. The arbitrator shall be a retired or former judge of any United States District Court or Court of Appeals or such other qualified person as the relevant parties may agree to designate, provided such individual has


had substantial professional experience with regard to settling commercial disputes. The parties intend that the provisions to arbitrate set forth herein be valid, enforceable and irrevocable. The designation of a situs or a governing law for this Agreement or the arbitration shall not be deemed an election to preclude application of the Federal Arbitration Act, if it would be applicable. In his award the arbitrator shall allocate, in his discretion, among the parties to the arbitration all costs of the arbitration, including the fees and expenses of the arbitrator and reasonable attorneys' fees, costs and expert witness expenses of the parties. The undersigned agree to comply with any award made in any such arbitration pro ceedings that has become final in accordance with the Rules and agree to the entry of a judgment in any jurisdiction upon any award rendered in such proceedings becoming final under the Rules. The arbitrator shall be entitled, if appropriate, to award any remedy in such proceedings, including monetary damages, specific performance and all other forms of legal and equitable relief; provided, however, the arbitrator shall not be entitled to award punitive damages.

ARTICLE VI

Insurance

SECTION 6.01. Coverage. (a) As of the Distribution Date, coverage of Arch and its Subsidiaries shall cease under current Company Policies, except as provided in this Article VI. From and after the Distribution Date, Arch and its Subsidiaries will be responsible for obtaining and maintaining insurance coverages for their own account. To the extent that Arch bears or incurs Arch Liabilities arising from the activities of Olin or its Subsidiaries prior to the Distribution Date, and which Arch Liabilities are covered by Company Policies, it is the intention of the parties that, without increasing or expanding the risks assumed by the insurer, Arch will have the benefit of such insurance coverage after the Distribution Date. No assignment pursuant to Section 6.02 is intended to increase the liability of any insurer under a Company Policy, and Olin shall be deemed to assign only such coverage as would have been available to Olin in respect of the Arch Business if the Distribution had not occurred.

(b) To the extent that Olin bears or incurs Olin Liabilities arising from the activities of Hunt prior to the Distribution Date, and which Olin Liabilities are covered by Hunt Policies, it is the intention of the parties that,


without increasing or expanding the risks assumed by the insurer, Olin will have the benefit of such insurance coverage after the Distribution Date. No assignment pursuant to Section 6.02 is intended to increase the liability of any insurer under a Hunt Policy, and Arch shall be deemed to assign only such coverage as would have been available in respect of the activities of Hunt if the Distribution had not occurred.

SECTION 6.02. Claims Based Upon Pre-Distribution Date Injury; Waiver. (a) If (i) prior to the Distribution Date, any person has asserted a claim or instituted a suit, action or proceeding against Olin or Arch, or
(ii) subse quent to the Distribution Date, any person shall assert a claim or institute a suit, action or proceeding against Arch or any of its Subsidiaries, in either case, with respect to any injury, loss, liability, damage or expense incurred or claimed to have been incurred prior to the Distribution Date in the course of or in connection with the conduct of the Arch Business and which injury, loss, liability, damage or expense may constitute an insured or insurable occurrence under one or more Company Policies, Olin shall be deemed, without need of further documentation, to assign to Arch or any of its Subsidiaries an interest in the relevant Company Policies (unless such assignment would render Olin's coverage for such occurrence thereunder void), subject to any limitations or obligations of Arch contemplated by this Article VI, if necessary, and then only to the extent necessary, to convey to Arch or any of its Subsidiaries rights of indemnity and the right to be defended by or at the expense of the insurer, with respect to any such claim, suit, action, proceeding, injury, loss, liability, damage or expense; provided, however, that, with respect to Company Policies for which Arch has payment obligations pursuant to Section 6.05 or otherwise, Arch and its Subsidiaries shall only have the rights set forth under this Section 6.02(a) with respect to such Company Policies if such payment obli gations have been satisfied by Arch.

(b) If (i) prior to the Distribution Date, any person has asserted a claim or instituted a suit, action or proceeding against Olin, or (ii) subsequent to the Distri bution Date, any person shall assert a claim or institute a suit, action or proceeding against Olin, in either case, with respect to any injury, loss, liability, damage or expense incurred or claimed to have been incurred prior to the Distribution Date in the course of or in connection with the activities of Hunt and which injury, loss, liability, damage or expense may constitute an insured or insurable occurrence under one or more Hunt Policies, Arch shall be deemed, without need or further documentation, to assign to


Olin an interest in the relevant Hunt Policies (unless such assignment would render Arch's coverage for such occurrence thereunder void), subject to any limitations or obligations of Olin contemplated by this Article VI, if necessary, and then only to the extent necessary, to convey to Olin rights of indemnity and the right to be defended by or at the expense of the insurer, with respect to any such claim, suit, action, proceeding, injury, loss, liability, damage or expense; provided, however, that, with respect to Hunt Policies for which Olin has payment obligations pursuant to
Section 6.05 or otherwise, Olin shall only have the rights set forth under this Section 6.02(b) with respect to such Hunt Policies if such payment obligations have been satis fied by Olin.

(c) Olin shall at all times retain the Company Policies, together with the rights, benefits and privileges thereunder, including the right to invade or exhaust any Company Policy by submission of claims, settlement or otherwise; provided, that the retention of the Company Policies by Olin is not intended to limit, inhibit or preclude any right granted pursuant to
Section 6.02(a), and provided further that Section 6.02(a) is not intended to limit, inhibit or preclude any rights, benefits or privi leges Olin may have under Company Policies. Arch hereby specifically agrees that Olin, in its sole discretion, may at any time and without the consent of Arch or any of its Subsidiaries, grant a release, given in good faith, to any insurance carrier absolving such carrier from further liability to Arch pursuant to any Company Policy, only in respect of Litigated Arch Liabilities (as defined below). Olin shall notify Arch of the terms and conditions of any such release prior to its execution. Any release by Olin of coverage obligations under any Company Policy in respect of Arch Liabilities other than or in addition to those in respect of Litigated Arch Liabilities shall require the written consent of Arch, which consent shall not be unreasonably withheld.

(d) Arch shall at all times retain the Hunt Policies, together with the rights, benefits and privileges thereunder, including the right to invade or exhaust any Hunt Policy by submission of claims, settlement or other wise; provided, that the retention of the Hunt Policies by Arch is not intended to limit, inhibit or preclude any right granted pursuant to
Section 6.02(b), and provided further that Section 6.02(b) is not intended to limit, inhibit or preclude any rights, benefits or privileges that Arch may have under the Hunt Policies. Arch hereby agrees that Olin, in its sole discretion, may at any time and without the consent of Arch grant a release, given in good faith, to any


insurance carrier absolving such carrier from further liability to Arch pursuant to any Hunt Policy only in respect of Litigated Arch Liabilities. Olin shall notify Arch of the terms and conditions of any such release prior to its execution. Any release by Arch of coverage obliga tions under any Hunt Policy in respect of Olin Liabilities shall require the written consent of Olin, which consent shall not be unreasonably withheld.

SECTION 6.03. Administration. Except as provided in the third sentence of this Section 6.03, from and after the Distribution Date, Olin shall be responsible for Claims Administration with respect to Olin Liabilities and Arch or a Subsidiary of Arch, as appropriate, shall be responsible for Claims Administration with respect to Arch Liabilities. Except as provided in the third sentence of this Section 6.03, Olin hereby appoints Arch as its agent and attorney in fact to perform Claims Administration under Company Policies with respect to claims against Olin which are or may give rise to Arch Liabilities, and Arch hereby appoints Olin as its agent and attorney in fact to perform Claims Administration under Hunt Policies with respect to claims against Arch or Hunt which are or may give rise to Olin Liabilities. Notwithstanding the foregoing, Olin shall be responsible for Claims Administration with respect to Arch Liabilities with respect to which Olin is engaged in coverage litigation, as of the Distribution Date, related to environmental remediation, and with respect to Arch Liabilities related to environmental remediation which become known after the Distribution Date, and which Olin shall add to said coverage litigation, if then still pending ("Litigated Arch Liabilities").

SECTION 6.04. Insurance Proceeds. Proceeds received with respect to claims made under Company Policies or Hunt Policies shall be paid to Olin with respect to Olin Liabilities and to Arch with respect to Arch Liabilities; provided, that proceeds received with respect to Litigated Arch Liabilities shall be allocated between Olin and Arch pro rata based on the remediation related amounts actually expended by the parties in connection therewith.

SECTION 6.05. Retrospectively Rated Policies. From and after the Distribution Date, any additional premiums payable or rebates of premiums previously paid in respect of any retrospectively rated Company Policy shall be paid or collected by Olin. Olin shall be reimbursed by Arch, or shall distribute to Arch, amounts equal to the portion of any such additional premium or rebate, as applicable, which relates to the Arch Business. From and after the Distribution Date, any additional premiums payable


or rebates of premiums previously paid in respect of any retrospectively rated Hunt Policy shall be paid or collected by Arch. Arch shall be reimbursed by Olin, or shall distri bute to Olin, amounts equal to the portion of any such additional premium or rebate, as applicable, which do not relate to the Arch Business.

SECTION 6.06. Agreement for Waiver of Conflict and Shared Defense. In the event that Insured Claims of more than one of the parties hereto exist relating to the same occurrence, the parties shall jointly defend and waive any conflict of interest necessary to the conduct of the joint defense. Nothing in this Section 6.06 shall be construed to limit or otherwise alter in any way the obliga tions of the parties to this Agreement, including those created by this Agreement, by operation of law or otherwise.

SECTION 6.07. Cooperation. The parties hereto agree to use their commercially reasonable efforts to cooperate with respect to the various insurance matters contemplated by this Agreement. If the product aggregates in the Company Policies or the Hunt Policies become exhausted, the parties agree to share the losses which otherwise would have been reimbursed by such Policies, but for the exhaustion of such product aggregates, on terms and in proportions that are equitable under the circumstances.

ARTICLE VII

Indemnification

SECTION 7.01. Indemnification. (a) Arch shall indemnify, defend and hold harmless Olin, each Affiliate of Olin and each of their respective directors, officers, employees and agents, and each of the heirs, successors and assigns of any of the foregoing (the "Olin Indemnitees") from and against all claims, damages, losses, liabilities, fines, penalties, costs and expenses (including without limitation reasonable attorneys' fees and disbursements) (collectively, "Indemnifiable Losses") of the Olin Indemnitees arising out of, associated with, or resulting from the Arch Liabilities (including without limitation the failure or alleged failure by Arch to pay, perform or otherwise discharge such Arch Liabilities in accordance with their terms), whether such Indemnifiable Losses relate to or arise from events, occurrences, actions, omissions, facts or circumstances occurring or existing, or whether such Indemnifiable Losses are asserted, before, on or after the Distribution Date.


(b) Olin shall indemnify, defend and hold harmless Arch, each Affiliate of Arch and each of their respective directors, officers, employees and agents, and each of the heirs, successors and assigns of any of the foregoing (the "Arch Indemnitees") from and against all Indemnifiable Losses of the Arch Indemnitees arising out of, associated with, or resulting from the Olin Liabilities (including without limitation the failure or alleged failure by Olin to pay, perform or otherwise discharge such Olin Liabilities in accordance with their terms), whether such Indemnifiable Losses relate to or arise from events, occurrences, actions, omissions, facts or circumstances occurring or existing, or whether such Indemnifiable Losses are asserted, before, on or after the Distribution Date.

SECTION 7.02. Insurance Matters. The amount which any indemnifying party (an "Indemnifying Party") is or may be required to pay to any indemnified party (an "Indemnified Party") under this Article VII shall be reduced (including without limitation retroactively) by any proceeds of insurance policies or other amounts actually recovered by or on behalf of such Indemnified Party in reduction of the related Indemnifiable Loss. If an Indemnified Party shall have received the payment (an "Indemnity Payment") required by this Agreement from an Indemnifying Party in respect of any Indemnifiable Loss and shall subsequently actually receive proceeds of insurance policies or other amounts in respect of such Indemnifiable Loss, then such Indemnified Party shall pay to such Indemnifying Party a sum equal to the amount actually received (up to but not in excess of the amount of any Indemnity Payment made hereunder). An insurer who would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto, or, solely by virtue of the indemnification provisions of this Article VII, or have any subrogation rights with respect thereto, it being expressly understood and agreed that no insurer or any other third party shall be entitled to a benefit they would not otherwise be entitled to receive in the absence of the indemnification provisions hereof by virtue of the indemnification provisions hereof.

SECTION 7.03. Procedures for Indemnification. (a) Pending Claims.
(i) On the Distribution Date, Arch shall assume (or shall cause one of its wholly owned Subsidiaries to assume) (A) the prosecution of all claims of Arch and (B) the defense against all Pending Litigation Matters, in each case, that are listed on Schedule 1.01(f).

(ii) Arch shall be responsible for attorneys' fees, disbursements and other costs related to the claims set forth in Section 7.03(a)(i) only as and to the extent


that such costs are accrued or incurred subsequent to the Distribution Date, and shall not be responsible for any of such costs to the extent accrued or incurred on or prior to the Distribution Date.

(b) Third Party Claims. (i) If a claim or demand is made against an Indemnified Party by any person who is not a party to this Agreement (a "Third Party Claim") as to which such Indemnified Party is entitled to indemnification pursuant to this Agreement, such Indemnified Party shall notify the Indemnifying Party in writing, and in reasonable detail, of the Third Party Claim promptly (and in any event within 15 business days) after receipt by such Indemnified Party of written notice of the Third Party Claim; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party shall have been actually prejudiced as a result of such failure (except that the Indemnifying Party shall not be liable for any expenses incurred during the period in which the Indemnified Party failed to give such notice). Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, promptly (and in any event within 15 business days) after the Indemnified Party's receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third Party Claim.

(ii) If a Third Party Claim is made against an Indemnified Party, the Indemnifying Party shall be entitled to participate in the defense thereof and, if it so chooses and acknowledges in writing its obligation to indemnify the Indemnified Party therefor, to assume the defense thereof with counsel selected by the Indemnifying Party; provided, however, that such counsel is not reasonably objected to by the Indemnified Party. Should the Indemnifying Party so elect to assume the defense of a Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof. If the Indemnifying Party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indem nifying Party, it being understood that the Indemnifying Party shall control such defense. The Indemnifying Party shall be liable for the fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party has failed to assume the defense thereof (other than during the period prior to the time the Indemnified Party shall have given notice of the Third Party Claim as provided above). If the Indemnifying


Party so elects to assume the defense of any Third Party Claim, the Indemnified Party shall cooperate with the Indemnifying Party in the defense or prosecution thereof.

(iii) If the Indemnifying Party acknowledges in writing its obligation to indemnify the Indemnified Party for a Third Party Claim, then in no event will the Indemnified Party admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without the Indemnifying Party's prior written consent; provided, however, that the Indemnified Party shall have the right to settle, compromise or discharge such Third Party Claim without the consent of the Indemnifying Party if the Indemnified Party releases the Indemnifying Party from its indemnification obligation hereunder with respect to such Third Party Claim and such settlement, compromise or discharge would not otherwise adversely affect the Indem nifying Party. If the Indemnifying Party acknowledges in writing its obligation to indemnify the Indemnified Party for a Third Party Claim, the Indemnified Party will agree to any settlement, compromise or discharge of a Third Party Claim that the Indemnifying Party may recommend and that by its terms obligates the Indemnifying Party to pay the full amount of the liability in connection with such Third Party Claim and releases the Indemnified Party completely in connection with such Third Party Claim and that would not otherwise adversely affect the Indemnified Party; provided, however, that the Indemnified Party may refuse to agree to any such settlement, compromise or discharge if the Indemnified Party agrees that the Indemnifying Party's indemnification obligation with respect to such Third Party Claim shall not exceed the amount that would be required to be paid by or on behalf of the Indemnifying Party in connection with such settlement, compromise or discharge.

(iv) Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to assume the defense of any Third Party Claim (and shall be liable for the fees and expenses of counsel incurred by the Indemnified Party in defending such Third Party Claim) if the Third Party Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the Indemnified Party which the Indemnified Party reasonably determines, after conferring with its counsel, cannot be separated from any related claim for money damages. If such equitable relief or other relief portion of the Third Party Claim can be so separated from that for money damages, the Indem nifying Party shall be entitled to assume the defense of the portion relating to money damages.


SECTION 7.04 Indemnification Payments. Indemnification required by this Agreement, shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnifiable Loss is incurred.

SECTION 7.05 Other Adjustments. (a) The amount of any indemnification obligation with respect to any Third Party Claim ("Indemnity Obligation") shall be (x) increased to take into account any net tax cost actually incurred by the Indemnified Party arising from any payments received from the Indemnifying Party (grossed up for such increase) and (y) reduced to take into account any net tax benefit actually realized by the Indemnified Party arising from the incurrence or payment of any such Indemnity Obligation. In computing the amount of such tax cost or tax benefit, the Indemnified Party shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt of any payment with respect to an Indemnity Obligation or the incurrence or payment of any Indemnity Obligation.

(b) In addition to any adjustments required pursuant to Section 7.02 hereof or clause (a) of this Section 7.05, and subject to such clause
(a), if the amount of any Indemnity Obligation shall, at any time subsequent to the payment required by this Agreement, be reduced by recovery, settlement or otherwise, the amount of such reduction, less any expenses incurred in connection therewith, shall promptly be repaid by the Indemnified Party to the Indemnifying Party up to the aggregate amount of any payments received from such Indemnifying Party pursuant to this Agreement in respect of such Indemnity Obligation.

SECTION 7.06. Consolidation, Merger, Transfer, or Lease. Neither Party shall consolidate with or merge into any other person, or convey, transfer or lease its properties and assets substantially as an entirety to any other person unless:

(a) The person formed by such consolidation or into which said Party is merged or the person which acquires by conveyance or transfer, or which leases the properties and assets of said Party substantially as an entirely shall (i) be a corporation, (ii) be organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia and (iii) expressly assume, by an instrument satisfactory to the other Party, each and every obligation of said Party to be performed or observed hereunder; and


(b) Said Party shall have delivered to the other Party a Certificate executed by its Chief Executive Officer and Chief Financial Officer stating that such consolidation, merger, conveyance, transfer or lease complies with this Section 7.06 and that all conditions precedent herein relating to such transaction have been complied with.

SECTION 7.07. Survival. All the indemnity obligations under this Article VII shall survive indefinitely.

SECTION 8.22. Severability. In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions, the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

4

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender's share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at

(b) To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Revolving Borrowing of the Type resulting from such election to be made on the effective date of such election.

28

such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Revolving Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Revolving Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

(e) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and, in the case of Revolving Loans, upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (d) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the end of the Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Revolving Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(f) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

32

SECTION 2.12 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(b) the Administrative Agent is advised by the Required Lenders (or, in the case of a Eurodollar Competitive Loan, the Lender that is required to make such Loan) that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Revolving Borrowing to, or continuation of any Revolving Borrowing as, a Eurodollar Borrowing shall be ineffective, (ii) if any Borrowing Request requests a Eurodollar Revolving Borrowing, such Borrowing shall be made as an ABR Borrowing and (iii) any request by the Borrower for a Eurodollar Competitive Borrowing shall be ineffective; provided that (A) if the circumstances giving rise to such notice do not affect all the Lenders, then requests by the Borrower for Eurodollar Competitive Borrowings may be made to Lenders that are not affected thereby and (B) if the circumstances giving rise to such notice affect only one Type of Borrowings, then the other Type of Borrowings shall be permitted.

SECTION 2.13 Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or

(ii) impose on any Lender or the London interbank market any other condition affecting this Agreement, Eurodollar Loans or Fixed Rate Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan or Fixed Rate Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or to reduce the amount of any

33

sum received or receivable by such Lender hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender, for such additional costs incurred or reduction suffered.

(b) If any Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender's capital or on the capital of such Lender's holding company, if any, as a consequence of this Agreement or the Loans made by, such Lender, to a level below that which such Lender or such Lender's holding company could have achieved but for such Change in Law (taking into consideration such Lender's policies and the policies of such Lender's holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender's holding company for any such reduction suffered.

(c) A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender's right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender's intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

(e) Notwithstanding the foregoing provisions of this Section, a Lender shall not be entitled to compensation pursuant to this Section in respect of any Competitive Loan if the Change in Law that would otherwise entitle it to such compensation shall have been publicly announced prior to submission of the Competitive Bid pursuant to which such Loan was made.

SECTION 2.14 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan or Fixed Rate Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Revolving Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.09(b) and is revoked in accordance therewith), (d) the failure to borrow any Competitive Loan after accepting the Competitive Bid to make

34

such Loan, or (e) the assignment of any Eurodollar Loan or Fixed Rate Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.17, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.15 Taxes.

(a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Borrower shall indemnify the Administrative Agent, each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. The Administrative Agent, each Lender and the Issuing Bank will, at the Borrower's expense, cooperate in

35

good faith with the Borrower in any contest as to whether or not such Indemnified Taxes, Other Taxes, penalties, interest or expenses were correctly or legally imposed or asserted in the event such Indemnified Taxes, Other Taxes, penalties, interest or expenses were in the good faith judgment of the Administrative Agent, such Lender or the Issuing Bank, as the case may be, not legal or not correctly asserted. If in connection with such contest such Indemnified Taxes, Other Taxes, penalties, interest or expenses are refunded to the Administrative Agent, such Lender or the Issuing Bank, the Administrative Agent, such Lender or the Issuing Bank will pay such refund to the Borrower to the extent the Administrative Agent, such Lender or the Issuing Bank, determines in its sole discretion that such refund is attributable to any Indemnified Taxes, Other Taxes, penalties, interest or expenses paid by the Borrower and to the extent the Borrower has previously indemnified the Administrative Agent, such Lender or the Issuing Bank therefor pursuant to this
Section 2.17, net of expenses and without interest except any interest (net of taxes) included in such refund. The Borrower shall return such refund (together with any taxes, penalties or other charges) in the event the Administrative Agent, such Lender or the Issuing Bank is required to repay such refund. Notwithstanding the foregoing, nothing in this Section 2.17 shall be construed to (i) entitle the Borrower or any other Persons to any information determined by the Administrative Agent, any Lender or the Issuing Bank, in each case, in its sole discretion, to be confidential or proprietary information of the Administrative Agent, any Lender or the Issuing Bank, to any tax or financial information of the Administrative Agent, any Lender or the Issuing Bank or to inspect or review any books and records of the Administrative Agent, any Lender or the Issuing Bank, or (ii) interfere with the rights of the Administrative Agent, any Lender or the Issuing Bank to conduct its fiscal or tax affairs in such matter as it deems fit.
A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate.

36

SECTION 2.16 Payments Generally; Pro Rata Treatment; Sharing of Set- offs.

(a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees, or of amounts payable under
Section 2.13, 2.14 or 2.15, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 270 Park Avenue, New York, New York, except that payments pursuant to Sections 2.13, 2.14, 2.15 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Revolving Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Revolving Loans then due and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Revolving Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Revolving Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and
(ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and

37

agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(b) or 2.16(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender's obligations under such Sections until all such unsatisfied obligations are fully paid.

SECTION 2.17 Mitigation Obligations; Replacement of Lenders.

(a) If any Lender requests compensation under Section 2.13, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.13 or 2.15, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If any Lender requests compensation under Section 2.13, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions

38

contained in Section 9.04), all its interests, rights and obligations under this Agreement (other than any outstanding Competitive Loans held by it) to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans (other than Competitive Loans), accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.13 or payments required to be made pursuant to Section 2.15, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

SECTION 2.18 Extension of Commitments. The Commitments may be extended in the manner set forth in, and subject to the conditions contained in, this Section 2.18. If the Borrower wishes to request an extension of the Commitments, it shall give notice to that effect to the Administrative Agent not less than 30 nor more than 60 days prior to the Maturity Date, whereupon the Administrative Agent shall promptly notify each of the Lenders of such request. Each such extension of Commitments shall be effective only with respect to each Lender which, by written notice (a "Continuation Notice") to the Borrower and the Administrative Agent given no earlier than 30 days prior to the Maturity Date, consents to such extension (each Lender which has given a Continuation Notice being a "Continuing Lender", and each Lender other than a Continuing Lender being a "Non-Continuing Lender"). The Commitments of each Continuing Lender shall be extended for a period of 364 days from the effective date set forth in an Extension Agreement, in substantially the form of Exhibit C hereto, which has been duly completed and signed by the Borrower, the Administrative Agent and the Continuing Lenders parties thereto. Such Extension Agreement shall be executed and delivered no earlier than 30 days prior to the Maturity Date then in effect and the effective date set forth therein shall be no earlier than 29 days prior to the Maturity Date then in effect. No extension of the Commitments pursuant to this Section 2.18 shall be legally binding on any party hereto unless and until such party executes and delivers a counterpart of such Extension Agreement. The Commitment of each Non-Continuing Lender (to the extent such Lender has not assigned its Commitment to a Continuing Lender) shall terminate on the Maturity Date prior to giving effect to the Borrower's extension hereunder; and the Borrower shall pay, for the account of each such Non-Continuing Lender on such Maturity Date, the amounts then due and payable to such Non-Continuing Lender pursuant to this Agreement. No Lender shall have any obligation to extend its Commitment in the event of such a request by the Borrower hereunder.

39

No part of the proceeds of any Loans will be used for "buying" or "carrying" any "margin stock" within the respective meanings of each of the quoted terms under Regulation U as now and from time to time hereafter in effect that would cause the Loans to be in violation of the provisions of the Regulations of the Board.

(ii) declare the Loans then outstanding to be due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall become due and payable immediately, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower; and in case of any event with respect to the Borrower described in clause (h) or (i) of this Article, the Commitments shall automatically terminate and the principal of the Loans then outstanding, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower.

ARTICLE VIII

The Administrative Agent, Syndication Agent and Documentation Agent

In order to expedite the transactions contemplated by this Agreement, each of the Lenders hereby irrevocably appoints the Administrative Agent, the Syndication Agent and the Documentation Agent (collectively, the "Agents") as its agent and authorizes each Agent to take such actions on its behalf and to exercise such powers as are delegated to each Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto.

Each bank serving as an Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and each such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

The Syndication Agent and the Documentation Agent, in their capacities as such, shall have no duties, obligations or liabilities of any kind hereunder. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing,
(a) no Agent shall be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in
Section 9.02), (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity and (d) the Administrative Agent will upon becoming aware of the occurrence of a Default give notice of such Default to each Lender. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or wilful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition

58

set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent's resignation hereunder, the provisions of this Article and
Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.

59

Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

SECTION 9.02 Waivers; Amendments.

(a) No failure or delay by the Administrative Agent or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the

61

generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.16(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, or (v) change any of the provisions of this Section or the definition of "Required Lenders" or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent without the prior written consent of the Administrative Agent.

SECTION 9.03 Expenses; Indemnity; Damage Waiver.

(a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated) and (ii) all out-of-pocket expenses incurred by the Administrative Agent or any Lender, including the fees, charges and disbursements of counsel for the Administrative Agent or such Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with the Loans made hereunder, including all such out- of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans.

(b) The Borrower shall indemnify the Administrative Agent and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an "Indemnitee") against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee

62

arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or the use of the proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or wilful misconduct of such Indemnitee.

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent, such Lender's Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such.

(d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable promptly after written demand therefor.

SECTION 9.04 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that, other than as part of the Company Closing, the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

63

(b) Any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that (i) except in the case of an assignment to a Lender or an Affiliate of a Lender, each of the Borrower and the Administrative Agent must give their prior written consent to such assignment (which consent shall in any case not be unreasonably withheld; it being understood that it is not unreasonable to withhold consent with respect to any proposed assignment to any financial institution having net capital and surplus of less than $1,000,000,000 or senior, unsecured, long-term indebtedness for borrowed money with a credit rating of less than A-), (ii) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender's Commitment, the amount of the Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than $10,000,000 and after giving effect thereto, the assigning Lender must have Commitments and Loans aggregating at least $5,000,000, unless each of the Borrower and the Administrative Agent otherwise consent, (iii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender's rights and obligations under this Agreement, except that this clause (iii) shall not apply to rights in respect of outstanding Competitive Loans, (iv) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500, and (v) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire; and provided further that any consent of the Borrower otherwise required under this paragraph shall not be required if an Event of Default under clause (h) or (i) of Article VII has occurred and is continuing. Subject to acceptance and recording thereof pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Acceptance the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.13, 2.14, 2.15 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (e) of this Section. By executing and delivering an Assignment and Acceptance, the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (1) such assigning Lender warrants that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim and that its Commitment, and the outstanding balances of its Loans, in each case without giving effect to assignments thereof which have not become effective, are as set forth in such Assignment and Acceptance, (2) except as set forth in (1) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements,

64

warranties or representations made in or in connection with this Agreement, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto, or the financial condition of the Borrower or any of its Subsidiaries or the performance or observance by the Borrower or any of its Subsidiaries of any of its obligations under this Agreement, any Loan Document or any other instrument or document furnished pursuant hereto, (3) such assignee represents and warrants that it is legally authorized to enter into such Assignment and Acceptance; (4) such assignee confirms that it has received a copy of this Agreement, together with copies of the most recent financial statements referred to in Section 3.04 or delivered pursuant to Section 5.01 and such other documents and information as it has been deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (5) such assignee will independently and without reliance upon any Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (6) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto, and (7) such assignee agrees that it will perform in accordance with their terms all the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

(c) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in The City of New York a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee's completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph
(b) of this Section, the Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(e) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (a "Participant") in all or a portion of such Lender's rights and obligations under this Agreement (including all or a

65

portion of its Commitment and the Loans owing to it); provided that (i) such Lender's obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to
Section 9.02(b) that affects such Participant. Subject to paragraph (f) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.13, 2.14 and 2.15 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.16(c) as though it were a Lender.

(f) A Participant shall not be entitled to receive any greater payment under Section 2.13 or 2.15 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower's prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.15 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.15(e) as though it were a Lender.

(g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION 9.05 Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid and so long as the Commitments have not

66

expired or terminated. The provisions of Sections 2.13, 2.14, 2.15 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans and the Commitments or the termination of this Agreement or any provision hereof.

SECTION 9.06 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 9.07 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 9.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 9.09 Governing Law; Jurisdiction; Consent to Service of Process.

(a) This Agreement shall be construed in accordance with and governed by the law of the State of New York.

67

(b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against the Borrower or its properties in the courts of any jurisdiction.

(c) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 9.10 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

68

SECTION 9.11 Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

SECTION 9.12 Confidentiality. Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates' directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section, "Information" means all information received from the Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by the Borrower; provided that, in the case of information received from the Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 9.13 Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the "Charges"), shall exceed the maximum lawful rate (the "Maximum Rate") which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

69

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.

OPINION OF COUNSEL FOR THE BORROWER

[Closing Date]

To the Lenders and the Administrative
Agent Referred to Below
c/o The Chase Manhattan Bank, as
Administrative Agent
270 Park Avenue
New York, New York 10017

Dear Sirs:

We have acted as counsel for Arch Chemicals, Inc., a Virginia corporation ("Arch"), and Olin Corporation, a Virginia corporation ("Olin"; and

together with Arch, the "Loan Parties"), in connection with the (a) Five Year Credit Agreement dated as of the date hereof (as the same may be amended, supplemented or otherwise modified from time to time, the "Five Year Credit Agreement") among the Loan Parties, the lenders and agents party thereto and The Chase Manhattan Bank, as administrative agent for the lenders and (b) 364-Day Credit Agreement dated as of the date hereof (as the same may be amended, supplemented or otherwise modified from time to time, the "364-Day Credit Agreement"; and together with the Five Year Credit Agreement, the "Credit
Agreements") among the Loan Parties, the lenders and agents party thereto and The Chase Manhattan Bank, as administrative agent for the lenders. Terms defined in the Credit Agreements are used herein with the same meanings.

We have examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as we have deemed necessary or advisable for purposes of this opinion.

Upon the basis of the foregoing, we are of the opinion that:

1. Each of the Loan Parties (a) is a corporation duly organized, validly existing and in good standing under the laws of Virginia/1/, (b) has all requisite power and authority to carry on its business as now conducted and
(c) except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required.


/1/ Virginia counsel opinion


2. The Transactions are within each Loan Party's corporate powers and have been duly authorized by all necessary corporate and, if required, stockholder action. The Credit Agreements and promissory notes issued pursuant thereto have been duly executed and delivered by each Loan Party which is a party thereto and each constitutes a legal, valid and binding obligation of each Loan Party which is a party thereto, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors' rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

3. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect, (b) will not violate any applicable law or regulation or the charter, by-laws or other organizational documents of either Loan Party or any of their respective Subsidiaries or any order of any Governmental Authority, (c) will not violate or result in a default under any indenture, agreement or other instrument binding upon either Loan Party or any of their respective Subsidiaries or their assets, or give rise to a right thereunder to require any payment to be made by either Loan Party or any of their respective Subsidiaries, and (d) will not result in the creation or imposition of any Lien on any asset of either Loan Party or any of their respective Subsidiaries.

4. There are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to our knowledge, threatened against or affecting either Loan Party or any of their respective Subsidiaries (a) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined, could reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect (other than the Disclosed Matters) or (b) that involve the Credit Agreements or the Transactions.

5. No Loan Party nor any of their respective Subsidiaries is (a) an "investment company" as defined in, or subject to regulation under, the Investment Company Act of 1940 or (b) a "holding company" as defined in, or subject to regulation under, the Public Utility Holding Company Act of 1935.

We are members of the bar of the State of New York and the foregoing opinion is limited to the laws of the State of New York and the Federal laws of the United States of America. This opinion is rendered solely to you in connection with the above matter. This opinion may not be relied upon by you for any other purpose or relied upon by any other Person (other than your successors and assigns as Lenders) without our prior written consent.

Very truly yours,

(ii) Funded or Current Debt of any Domestic Subsidiary secured by Liens permitted by the provisions of clause (v) of Section 5.02(a) or unsecured and either issued or assumed by such Subsidiary in connection with payment to sellers of properties or businesses acquired by such Subsidiary or payable by such Subsidiary and outstanding at the time it became a Subsidiary, provided that no such Subsidiary may create, incur, assume, guarantee or in any way become liable for any additional Funded or Current Debt permitted by this clause (ii) unless, immediately after giving effect thereto and to the concurrent repayment of any other Debt (A) the Debt limitations of clause (i) above will not thereby be violated, and (B) the aggregate principal amount of all Funded and Current Debt permitted by this clause (ii) plus, without duplication, the aggregate principal amount of all Funded and Current Debt of all Subsidiaries secured by Liens permitted by clauses (v) and (vi) of Section 5.02(a) shall not exceed an amount equal to 10% of Consolidated Net Tangible Assets, and further provided that no Funded or Current Debt permitted by this clause (ii) shall be extended or renewed or remain outstanding after its stated maturity,

Each such telephonic Competitive Bid Request shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Competitive Bid Request in a form approved by the Administrative Agent and signed by the Borrower. Each such telephonic and written Competitive Bid Request shall specify the following information in compliance with Section 2.02:

26

(i) the aggregate amount of the requested Borrowing;

(ii) the date of such Borrowing, which shall be a Business Day;

(iii) whether such Borrowing is to be a Eurodollar Borrowing or a Fixed Rate Borrowing;

(iv) the Interest Period to be applicable to such Borrowing, which shall be a period contemplated by the definition of the term "Interest Period"; and

(v) the location and number of the Borrower's account to which funds are to be disbursed, which shall comply with the requirements of
Section 2.07.

Promptly following receipt of a Competitive Bid Request in accordance with this Section, the Administrative Agent shall notify the Lenders of the details thereof by telecopy, inviting the Lenders to submit Competitive Bids.

(b) Each Lender may (but shall not have any obligation to) make one or more Competitive Bids to the Borrower in response to a Competitive Bid Request. Each Competitive Bid by a Lender must be in a form approved by the Administrative Agent and must be received by the Administrative Agent by telecopy, in the case of a Eurodollar Competitive Borrowing, not later than 9:30
a.m., New York City time, three Business Days before the proposed date of such Competitive Borrowing, and in the case of a Fixed Rate Borrowing, not later than 9:30 a.m., New York City time, on the proposed date of such Competitive Borrowing. Competitive Bids that do not conform substantially to the form approved by the Administrative Agent may be rejected by the Administrative Agent, and the Administrative Agent shall notify the applicable Lender as promptly as practicable. Each Competitive Bid shall specify (i) the principal amount (which shall be a minimum of $5,000,000 and an integral multiple of $1,000,000 and which may equal the entire principal amount of the Competitive Borrowing requested by the Borrower) of the Competitive Loan or Loans that the Lender is willing to make, (ii) the Competitive Bid Rate or Rates at which the Lender is prepared to make such Loan or Loans (expressed as a percentage rate per annum in the form of a decimal to no more than four decimal places) and
(iii) the Interest Period applicable to each such Loan and the last day thereof.

(c) The Administrative Agent shall promptly notify the Borrower by telecopy of the Competitive Bid Rate and the principal amount specified in each Competi tive Bid and the identity of the Lender that shall have made such Competitive Bid.

(d) Subject only to the provisions of this paragraph, the Borrower may accept or reject any Competitive Bid. The Borrower shall notify the Administrative Agent

27

by telephone, confirmed by telecopy in a form approved by the Administrative Agent, whether and to what extent it has decided to accept or reject each Competitive Bid, in the case of a Eurodollar Competitive Borrowing, not later than 10:30 a.m., New York City time, three Business Days before the date of the proposed Competitive Borrowing, and in the case of a Fixed Rate Borrowing, not later than 10:30 a.m., New York City time, on the proposed date of the Competitive Borrowing; provided that (i) the failure of the Borrower to give such notice shall be deemed to be a rejection of each Competitive Bid, (ii) the Borrower shall not accept a Competitive Bid made at a particular Competitive Bid Rate if the Borrower rejects a Competitive Bid made at a lower Competitive Bid Rate, (iii) the aggregate amount of the Competitive Bids accepted by the Borrower shall not exceed the aggregate amount of the requested Competitive Borrowing specified in the related Competitive Bid Request, (iv) to the extent necessary to comply with clause (iii) above, the Borrower may accept Competitive Bids at the same Competitive Bid Rate in part, which acceptance, in the case of multiple Competitive Bids at such Competitive Bid Rate, shall be made pro rata in accordance with the amount of each such Competitive Bid, and (v) except pursuant to clause (iv) above, no Competitive Bid shall be accepted for a Competitive Loan unless such Competitive Loan is in a minimum principal amount of $5,000,000 and an integral multiple of $1,000,000; provided further that if a Competitive Loan must be in an amount less than $5,000,000 because of the provisions of clause (iv) above, such Competitive Loan may be for a minimum of $1,000,000 or any integral multiple thereof, and in calculating the pro rata allocation of acceptances of portions of multiple Competitive Bids at a particular Competitive Bid Rate pursuant to clause (iv) the amounts shall be rounded to integral multiples of $1,000,000 in a manner determined by the Borrower. A notice given by the Borrower pursuant to this paragraph shall be irrevocable.

(e) The Administrative Agent shall promptly notify each bidding Lender by telecopy whether or not its Competitive Bid has been accepted (and, if so, the amount and Competitive Bid Rate so accepted), and each successful bidder will thereupon become bound, subject to the terms and conditions hereof, to make the Competitive Loan in respect of which its Competitive Bid has been accepted.

(f) If the Administrative Agent shall elect to submit a Competitive Bid in its capacity as a Lender, it shall submit such Competitive Bid directly to the Borrower at least one quarter of an hour earlier than the time by which the other Lenders are required to submit their Competitive Bids to the Administrative Agent pursuant to paragraph (b) of this Section.

SECTION 2.05 Swingline Loans.

(a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to the Borrower from time to time during the Availability Period, in an aggregate principal amount at any time outstanding that will not

28

result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding $10,000,000 or (ii) the sum of the total Revolving Credit Exposures plus the aggregate principal amount of outstanding Competitive Loans exceeding the total Commitments; provided that the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan and provided further that the Swingline Lender shall not be permitted to make a Swingline Loan upon the occurrence and during the continuance of a Default. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Swingline Loans.

(b) To request a Swingline Loan, the Borrower shall notify the Administrative Agent of such request by telephone (confirmed by telecopy), not later than 12:00 noon, New York City time, on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested date (which shall be a Business Day) and amount of the requested Swingline Loan. The Administrative Agent will promptly advise the Swingline Lender of any such notice received from the Borrower. The Swingline Lender shall make each Swingline Loan available to the Borrower by means of a credit to the general deposit account of the Borrower with the Swingline Lender (or, in the case of a Swingline Loan made to finance the reimbursement of an LC Disbursement as provided in Section 2.06(e), by remittance to the Issuing Bank) by 3:00 p.m., New York City time, on the requested date of such Swingline Loan.

(c) The Swingline Lender may by written notice given to the Administrative Agent not later than 10:00 a.m., New York City time, on any Business Day require the Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which Lenders will participate. Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each Lender, specifying in such notice such Lender's Applicable Percentage of such Swingline Loan or Loans. Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such Lender's Applicable Percentage of such Swingline Loan or Loans. Each Lender acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.07 with respect to Loans made by such Lender (and Section 2.07 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Lenders. The Administrative Agent shall notify the Borrower of any participations in any Swingline Loan acquired pursuant to this paragraph, and

29

thereafter payments in respect of such Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.

SECTION 2.06 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of Letters of Credit for its own account, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the Availability Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain
Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the Issuing Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank's standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension (i) the LC Exposure shall not exceed $25,000,000 and (ii) the sum of the total Revolving Credit Exposures plus the aggregate principal amount of outstanding Competitive Loans shall not exceed the total Commitments.

30

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date; provided, that any Letter of Credit with a one-year term may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (ii) above).

(d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender's Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Lender's Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon, New York City time, on (i) the Business Day that the Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that the Borrower may, subject to the conditions to borrowing set forth herein, request in accor dance with Section 2.03 or 2.05 that such payment be financed with an ABR Revolving Borrowing or Swingline Loan in an equivalent amount and, to the extent so financed, the Borrower's obligation to make such payment shall be discharged and replaced by the resulting ABR Revolving Borrowing or Swingline Loan; provided further that if such payment is not financed with an ABR Revolving Borrowing or Swingline Loan, the

31

Administrative Agent will extend an ABR Revolving Borrowing in the amount of such LC Disbursement. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender's Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.07 with respect to Loans made by such Lender (and Section 2.07 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing Bank for any LC Disbursement (other than the funding of ABR Revolving Loans or a Swingline Loan as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

(f) Obligations Absolute. The Borrower's obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower's obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the

32

Borrower that are caused by the Issuing Bank's failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or wilful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Revolving Loans; provided that, if the Borrower fails to reimburse such LC Dis bursement when due pursuant to paragraph (e) of this Section, then Section 2.13(d) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to
Section 2.12(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term "Issuing Bank" shall be

33

deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(j) Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing greater than 51% of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (h) or (i) of Article VII. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower's risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank and pro-rata to any Lender that has funded participations therein for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing greater than 51% of the total LC Exposure), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

SECTION 2.07 Funding of Borrowings.

(a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 12:00 noon, New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders; provided that Swingline Loans shall be

34

made as provided in Section 2.05. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in New York City and designated by the Borrower in the applicable Borrowing Request or Competitive Bid Request.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender's share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at
(i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender's Loan included in such Borrowing.

SECTION 2.08 Interest Elections.

(a) Each Revolving Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Revolving Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Revolving Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section shall not apply to Competitive Borrowings or Swingline Borrowings, which may not be converted or continued.

(b) To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Revolving Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a

35

written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be speci fied for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term "Interest Period".

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month's duration.

(d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender's portion of each resulting Borrowing.

(e) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Revolving Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Revolving Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Revolving Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

36

SECTION 2.09 Termination and Reduction of Commitments.

(a) Unless previously terminated, the Commitments shall terminate on the Maturity Date.

(b) The Borrower may at any time terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $5,000,000 and not less than $10,000,000 and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.11, the sum of the Revolving Credit Exposures plus the aggregate principal amount of outstanding Competitive Loans would exceed the total Commitments.

(c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments.

SECTION 2.10 Repayment of Loans; Evidence of Debt.

(a) The Borrower hereby unconditionally promises to pay (i) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan on the Maturity Date, (ii) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Competitive Loan on the last day of the Interest Period applicable to such Loan and (iii) to the Swingline Lender or, subject to Section 2.05(c), the Administrative Agent, the then unpaid principal amount of each Swingline Loan on the earlier of the Maturity Date and the first date after such Swingline Loan is made that is the 15th or last day of a calendar month and is at least two Business Days after such Swingline Loan is made.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

37

(c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Class and Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender's share thereof.

(d) The entries made in the accounts maintained pursuant to paragraph
(b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

SECTION 2.11 Prepayment of Loans.

(a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (b) of this Section; provided that the Borrower shall not have the right to prepay any Competitive Loan without the prior consent of the Lender thereof.

contemplated by Section 2.09, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.09. Promptly following receipt of any such notice relating to a Revolving Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Revolving Borrowing shall be in an amount that would be permitted in the case of an advance of a Revolving Borrowing of the same Type as provided in Section 2.02.

Accrued facility fees shall be payable in arrears on the last day of March, June, September and December of each year and on the date on which the Commitments terminate, commencing on the first such date to occur after the date hereof; provided that any facility fees accruing after the date on which the Commitments terminate shall be payable on demand.

(c) The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent.

(d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of facility fees and participation fees, to the Lenders. Fees paid shall not be refundable under any circumstances.

SECTION 2.13 Interest.

(a) The Loans comprising each ABR Borrowing (including each Swingline Loan) shall bear interest at the Alternate Base Rate plus the Applicable Rate.

(b) The Loans comprising each Eurodollar Borrowing shall bear interest
(i) in the case of a Eurodollar Revolving Loan, at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate, or
(ii) in the case of a Eurodollar Competitive Loan, at the LIBO Rate for the Interest Period in effect for such Borrowing plus (or minus, as applicable) the Margin applicable to such Loan.

(c) Each Fixed Rate Loan shall bear interest at the Fixed Rate applicable to such Loan.

(d) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any

40

other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph
(a) of this Section.

(e) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and, in the case of Revolving Loans, upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (d) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the end of the Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Revolving Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(f) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

SECTION 2.14 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(b) the Administrative Agent is advised by the Required Lenders (or, in the case of a Eurodollar Competitive Loan, the Lender that is required to make such Loan) that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Revolving Borrowing to, or continuation of any Revolving Borrowing as, a Eurodollar

41

Borrowing shall be ineffective, (ii) if any Borrowing Request requests a Eurodollar Revolving Borrowing, such Borrowing shall be made as an ABR Borrowing and (iii) any request by the Borrower for a Eurodollar Competitive Borrowing shall be ineffective; provided that (A) if the circumstances giving rise to such notice do not affect all the Lenders, then requests by the Borrower for Eurodollar Competitive Borrowings may be made to Lenders that are not affected thereby and (B) if the circumstances giving rise to such notice affect only one Type of Borrowings, then the other Type of Borrowings shall be permitted.

SECTION 2.15 Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the Issuing Bank; or

(ii) impose on any Lender or the Issuing Bank or the London interbank market any other condition affecting this Agreement, Eurodollar Loans or Fixed Rate Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan or Fixed Rate Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or the Issuing Bank hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compen sate such Lender or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

(b) If any Lender or the Issuing Bank determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender's or the Issuing Bank's capital or on the capital of such Lender's or the Issuing Bank's holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender's or the Issuing Bank's holding company could have achieved but for such Change in Law (taking into consideration such Lender's or the Issuing Bank's policies and the policies of such Lender's or the Issuing Bank's holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender

42

or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender's or the Issuing Bank's holding company for any such reduction suffered.

(c) A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender's or the Issuing Bank's right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender's or the Issuing Bank's intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

(e) Notwithstanding the foregoing provisions of this Section, a Lender shall not be entitled to compensation pursuant to this Section in respect of any Competitive Loan if the Change in Law that would otherwise entitle it to such compensation shall have been publicly announced prior to submission of the Competitive Bid pursuant to which such Loan was made.

SECTION 2.16 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan or Fixed Rate Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Revolving Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(b) and is revoked in accordance there with), (d) the failure to borrow any Competitive Loan after accepting the Competitive Bid to make such Loan, or (e) the assignment of any Eurodollar Loan or Fixed Rate Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.19, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of

43

interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.17 Taxes.

(a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. The Administrative Agent, each Lender and the Issuing Bank will, at the Borrower's expense, cooperate in good faith with the Borrower in any contest as to whether or not such Indemnified Taxes, Other Taxes, penalties, interest or expenses were correctly or legally imposed or asserted in the event such Indemnified Taxes, Other Taxes, penalties, interest or expenses were in the good faith judgment of the Administrative Agent, such Lender or the Issuing Bank, as the

44

case may be, not legal or not correctly asserted. If in connection with such contest such Indemnified Taxes, Other Taxes, penalties, interest or expenses are refunded to the Administrative Agent, such Lender or the Issuing Bank, the Administrative Agent, such Lender or the Issuing Bank will pay such refund to the Borrower to the extent the Administrative Agent, such Lender or the Issuing Bank, determines in its sole discretion that such refund is attributable to any Indemnified Taxes, Other Taxes, penalties, interest or expenses paid by the Borrower and to the extent the Borrower has previously indemnified the Administrative Agent, such Lender or the Issuing Bank therefor pursuant to this
Section 2.17, net of expenses and without interest except any interest (net of taxes) included in such refund. The Borrower shall return such refund (together with any taxes, penalties or other charges) in the event the Administrative Agent, such Lender or the Issuing Bank is required to repay such refund. Notwithstanding the foregoing, nothing in this Section 2.17 shall be construed to (i) entitle the Borrower or any other Persons to any information determined by the Administrative Agent, any Lender or the Issuing Bank, in each case, in its sole discretion, to be confidential or proprietary information of the Administrative Agent, any Lender or the Issuing Bank, to any tax or financial information of the Administrative Agent, any Lender or the Issuing Bank or to inspect or review any books and records of the Administrative Agent, any Lender or the Issuing Bank, or (ii) interfere with the rights of the Administrative Agent, any Lender or the Issuing Bank to conduct its fiscal or tax affairs in such matter as it deems fit. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate.

45

SECTION 2.18 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15, 2.16 or 2.17, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 270 Park Avenue, New York, New York, except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided herein and except that payments pursuant to Sections 2.15, 2.16, 2.17 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, letter of credit cash collateral obligations pursuant to
Section 2.06(j), interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties and (iii) third, to fund letter of credit cash collateral obligations pursuant to Section 2.06(j).

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Revolving Loans or participations in LC Disbursements or Swingline Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Revolving Loans then due and participations in LC Disbursements and Swingline Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Revolving Loans and participations in LC Disbursements and Swingline Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Revolving Loans and participations

46

in LC Disbursements and Swingline Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(c), 2.06(d) or (e), 2.07(b) or 2.18(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender's obligations under such Sections until all such unsatisfied obligations are fully paid.

SECTION 2.19 Mitigation Obligations; Replacement of Lenders.

(a) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices,

47

branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.15 or 2.17, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in
Section 9.04), all its interests, rights and obligations under this Agreement (other than any outstanding Competitive Loans held by it) to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent (and, if a Commitment is being assigned, the Issuing Bank and Swingline Lender), which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans (other than Competitive Loans) and participations in LC Disbursements and Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under
Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

ARTICLE VIII
The Administrative Agent, Syndication Agent and Documentation Agent

In order to expedite the transactions contemplated by this Agreement, each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent, the Syndication Agent and the Documentation Agent (collectively, the "Agents") as its agent and authorizes each Agent to take such actions on its behalf and to exercise such powers as

67

are delegated to each Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto.

Each bank serving as an Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and each such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

The Syndication Agent and the Documentation Agent, in their capacities as such, shall have no duties, obligations or liabilities of any kind hereunder. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing,
(a) no Agent shall be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in
Section 9.02), (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity and (d) the Administrative Agent will upon becoming aware of the occurrence of a Default give notice of such Default to each Lender. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or wilful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it

68

orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent's resignation hereunder, the provisions of this Article and
Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

SECTION 9.02 Waivers; Amendments.

(a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby,
(iii) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.18(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, or (v) change any of the provisions of this
Section or the definition of "Required Lenders" or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, the Issuing Bank or the Swingline Lender hereunder without the prior written consent of the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be.

72

SECTION 9.03 Expenses; Indemnity; Damage Waiver.

(a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of counsel for the Administrative Agent, the Issuing Bank or such Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

(b) The Borrower shall indemnify the Administrative Agent, the Issuing Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an "Indemnitee") against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or wilful misconduct of such Indemnitee.

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent, the Issuing Bank or the Swingline Lender under

73

paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be, such Lender's Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent, the Issuing Bank or the Swingline Lender in its capacity as such.

(d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable promptly after written demand therefor.

SECTION 9.04 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that, other than as part of the Company Closing, the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that (i) except in the case of an assignment to a Lender or an Affiliate of a Lender, each of the Borrower and the Administrative Agent (and, in the case of an assignment of all or a portion of a Commitment or any Lender's obligations in respect of its LC Exposure or Swingline Exposure, the Issuing Bank and the Swingline Lender) must give their prior written consent to such assignment (which consent shall in any case not be unreasonably withheld; it being understood that it is not unreasonable to withhold consent with respect to any proposed assignment to any financial institution having net capital and surplus of less than $1,000,000,000 or senior, unsecured, long-term

74

indebtedness for borrowed money with a credit rating of less than A-), (ii) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender's Commitment, the amount of the Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than $10,000,000 and after giving effect thereto, the assigning Lender must have Commitments and Loans aggregating at least $5,000,000, unless each of the Borrower and the Administrative Agent otherwise consent, (iii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender's rights and obligations under this Agreement, except that this clause (iii) shall not apply to rights in respect of outstanding Competitive Loans, (iv) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500, and (v) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire; and provided further that any consent of the Borrower otherwise required under this paragraph shall not be required if an Event of Default under clause (h) or (i) of Article VII has occurred and is continuing. Subject to acceptance and recording thereof pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Acceptance the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.15, 2.16, 2.17 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (e) of this Section. By executing and delivering an Assignment and Acceptance, the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (1) such assigning Lender warrants that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim and that its Commitment, and the outstanding balances of its Loans, in each case without giving effect to assignments thereof which have not become effective, are as set forth in such Assignment and Acceptance, (2) except as set forth in (1) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto, or the financial condition of the Borrower or any of its Subsidiaries or the performance or observance by the Borrower or any of its Subsidiaries of any of its obligations under this Agreement, any Loan Document or any other instrument or document furnished pursuant hereto, (3) such assignee represents and warrants that it is

75

legally authorized to enter into such Assignment and Acceptance; (4) such assignee confirms that it has received a copy of this Agreement, together with copies of the most recent financial statements referred to in Section 3.04 or delivered pursuant to Section 5.01 and such other documents and information as it has been deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (5) such assignee will independently and without reliance upon any Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (6) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto, and (7) such assignee agrees that it will perform in accordance with their terms all the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

(c) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in The City of New York a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Bank and any Lender, at any reason able time and from time to time upon reasonable prior notice.

(d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee's completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph
(b) of this Section, the Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(e) Any Lender may, without the consent of the Borrower, the Administrative Agent, the Issuing Bank or the Swingline Lender, sell participations to one or more banks or other entities (a "Participant") in all or a portion of such Lender's rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (i) such Lender's obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative

76

Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (f) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be subject to
Section 2.18(c) as though it were a Lender.

(f) A Participant shall not be entitled to receive any greater payment under Section 2.15 or 2.17 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower's prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.17(e) as though it were a Lender.

(g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION 9.05 Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.15, 2.16, 2.17 and 9.03

77

and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

SECTION 9.06 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in
Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 9.07 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 9.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 9.09 Governing Law; Jurisdiction; Consent to Service of Process.

(a) This Agreement shall be construed in accordance with and governed by the law of the State of New York.

78

(b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Administrative Agent, the Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against the Borrower or its properties in the courts of any jurisdiction.

(c) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 9.10 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

79

SECTION 9.11 Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

SECTION 9.12 Confidentiality. Each of the Administrative Agent, the Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates' directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder,
(f) subject to an agreement containing provisions substantially the same as those of this Section, to any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section, "Information" means all information received from the Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Borrower; provided that, in the case of information received from the Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 9.13 Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the "Charges"), shall exceed the maximum lawful rate (the "Maximum Rate") which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until

80

such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

OPINION OF COUNSEL FOR THE BORROWER

[Closing Date]

To the Lenders and the Administrative
Agent Referred to Below
c/o The Chase Manhattan Bank, as
Administrative Agent
270 Park Avenue
New York, New York 10017

Dear Sirs:

We have acted as counsel for Arch Chemicals, Inc., a Virginia corporation ("Arch"), and Olin Corporation, a Virginia corporation ("Olin"; and

together with Arch, the "Loan Parties"), in connection with the (a) Five Year Credit Agreement dated as of the date hereof (as the same may be amended, supplemented or otherwise modified from time to time, the "Five Year Credit Agreement") among the Loan Parties, the lenders and agents party thereto and The Chase Manhattan Bank, as administrative agent for the lenders and (b) 364-Day Credit Agreement dated as of the date hereof (as the same may be amended, supplemented or otherwise modified from time to time, the "364-Day Credit Agreement"; and together with the Five Year Credit Agreement, the "Credit
Agreements") among the Loan Parties, the lenders and agents party thereto and The Chase Manhattan Bank, as administrative agent for the lenders. Terms defined in the Credit Agreements are used herein with the same meanings.

We have examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as we have deemed necessary or advisable for purposes of this opinion.

Upon the basis of the foregoing, we are of the opinion that:

1. Each of the Loan Parties (a) is a corporation duly organized, validly existing and in good standing under the laws of Virginia/1/, (b) has all requisite power and authority to carry on its business as now conducted and
(c) except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required.


/1/ Virginia counsel opinion


2. The Transactions are within each Loan Party's corporate powers and have been duly authorized by all necessary corporate and, if required, stockholder action. The Credit Agreements and promissory notes issued pursuant thereto have been duly executed and delivered by each Loan Party which is a party thereto and each constitutes a legal, valid and binding obligation of each Loan Party which is a party thereto, enforce able in accordance with its terms, subject to applicable bankruptcy, insolvency, reorgani zation, moratorium or other laws affecting creditors' rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

3. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect, (b) will not violate any applicable law or regulation or the charter, by-laws or other organizational documents of either Loan Party or any of their respective Subsidiaries or any order of any Govern mental Authority, (c) will not violate or result in a default under any indenture, agreement or other instrument binding upon either Loan Party or any of their respective Subsidiaries or their assets, or give rise to a right thereunder to require any payment to be made by either Loan Party or any of their respective Subsidiaries, and (d) will not result in the creation or imposition of any Lien on any asset of either Loan Party or any of their respective Subsidiaries.

4. There are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to our knowledge, threatened against or affecting either Loan Party or any of their respective Subsidiaries (a) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined, could reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect (other than the Disclosed Matters) or (b) that involve the Credit Agreements or the Transactions.

5. No Loan Party nor any of their respective Subsidiaries is (a) an "investment company" as defined in, or subject to regulation under, the Investment Company Act of 1940 or (b) a "holding company" as defined in, or subject to regulation under, the Public Utility Holding Company Act of 1935.

We are members of the bar of the State of New York and the foregoing opinion is limited to the laws of the State of New York and the Federal laws of the United States of America. This opinion is rendered solely to you in connection with the above matter. This opinion may not be relied upon by you for any other purpose or relied upon by any other Person (other than your successors and assigns as Lenders) without our prior written consent.

Very truly yours,
