Item 2.01 Completion of Acquisition or Disposition of Assets.

On August 20, 2007, pursuant to the Agreement and Plan of Merger (the “ Merger Agreement ”), dated as of February 5, 2007, as amended, by and among Exterran Holdings, Inc. (formerly known as Iliad Holdings, Inc.) (the “ Company ”), Hanover Compressor Company, a Delaware corporation (“ Hanover ”), Universal Compression Holdings, Inc., a Delaware corporation (“ Universal ”), Hector Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Company (“ Hanover Merger Sub ”), and Ulysses Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Company (“ Universal Merger Sub ”), Universal Merger Sub merged with and into Universal (the “ Universal Merger ”) and Hanover Merger Sub merged with and into Hanover (the “ Hanover Merger ” and together with the Universal Mergers, the “ Mergers ”). As a result of the Mergers, each of Universal and Hanover became a wholly owned subsidiary of the Company. Immediately following the completion of the Mergers, Universal merged with and into the Company.

Pursuant to the Universal Merger, each share of common stock of Universal, par value $0.01 per share (the “ Universal Common Stock ”), was converted into the right to receive one share of the Company’s common stock, par value $0.01 per share. Pursuant to the Hanover Merger, each share of common stock of Hanover, par value $0.001 per share (the “ Hanover Common Stock ”), was converted into the right to receive 0.325 shares of the Company’s common stock. Pursuant to the merger of Universal with and into the Company, the capital stock of the surviving company of the Universal Merger was canceled.

The issuance of the Company’s common stock pursuant to the Mergers was registered under the Securities Act of 1933, as amended, pursuant to the Company’s registration statement on Form S-4 (File No. 333-141695) (the “ Registration Statement ”) filed with the Securities and Exchange Commission (the “ SEC ”) and declared effective on July 10, 2007. The definitive joint proxy statement/prospectus of Universal and Hanover, dated July 6, 2007, that forms a part of the Registration Statement (the “ Joint Proxy Statement/Prospectus ”) contains additional information about the Mergers and the other transactions contemplated by the Merger Agreement, including information concerning the interests of directors, executive officers and affiliates of Universal and Hanover in the Mergers.

Pursuant to Rule 12g-3(c) under the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), the Company’s common stock is deemed to be registered under Section 12(b) of the Exchange Act. The Company’s common stock has been approved for listing on the New York Stock Exchange and is expected to begin trading under the symbol “EXH” on August 21, 2007.

Each of the Universal Common Stock and the Hanover Common Stock was registered pursuant to Section 12(b) of the Exchange Act and listed on the New York Stock Exchange, and both the Universal Common Stock and the Hanover Common Stock are being delisted from the New York Stock Exchange. Each of Universal and Hanover expects to file a Form 15 with the SEC to terminate the registration under Section 12(g) and 15(d) of the Exchange Act of the Universal Common Stock and the Hanover Common Stock, respectively.

On August 20, 2007, the Company issued a press release announcing the completion of the Mergers and the other transactions contemplated by the Merger Agreement. The press release is attached hereto as Exhibit 99.1 and incorporated herein by reference.

Item 5.01 Changes in Control of Registrant.

Upon the completion of the Mergers on August 20, 2007, a change of control of the Company occurred. Immediately prior to the Universal Merger, Universal owned all of the issued and outstanding equity interests in the Company. Upon completion of the Mergers, pursuant to the terms and conditions of the Merger Agreement, Universal contributed its interest in the Company to the Company, and the former stockholders of Universal and Hanover became the stockholders of the Company in accordance with the share exchange provisions and ratios set forth in the Merger Agreement. As a result of the Mergers, each of Universal and Hanover became a wholly owned subsidiary of the Company. Immediately following the completion of the Mergers, Universal merged with and into the Company.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

In connection with and effective on the date of the Mergers, the Company amended and restated in their entirety its certificate of incorporation and by-laws substantially in the form attached as Exhibits 2.2.2 and 2.3.1 to the Merger Agreement and included in the Joint Proxy Statement/Prospectus (together with technical and conforming amendments thereto). The description of the certificate of incorporation and bylaws that was contained under the caption “Comparison of Stockholder Rights” in the Joint Proxy Statement/Prospectus is incorporated herein by reference. The Company’s restated certificate of incorporation and amended and restated bylaws are attached hereto as Exhibits 3.1 and 3.2, respectively, and incorporated herein by reference.

Item 7.01 Regulation FD Disclosure.

On August 16, 2007, Hanover and Universal issued a press release announcing that their stockholders had adopted the Merger Agreement and approved the adoption of the Exterran 2007 Stock Incentive Plan and the Exterran Employee Stock Purchase Plan. The press release is attached hereto as Exhibit 99.2 and incorporated herein by reference.

Item 8.01 Other Events.

Description of Capital Stock

The following summary of the Company’s capital stock is subject in all respects to the applicable provisions of the Delaware General Corporation Law (the “ DGCL ”), the Company’s restated certificate of incorporation and amended and restated bylaws. The following discussion is a summary of the Company’s restated certificate of incorporation and amended and restated bylaws and is qualified in its entirety by reference to those documents, which are attached as Exhibits 3.1 and 3.2, respectively, to this report.

General

The total number of authorized shares of capital stock of the Company consist of 250 million shares of common stock, par value one cent ($0.01) per share, and 50 million shares of preferred stock, par value one cent ($0.01) per share.

Preferred Stock

The board of directors of the Company is authorized, subject to any limitations prescribed by law, to provide by resolution for the issuance of authorized and unissued shares of preferred stock in one or more series, and by filing a certificate pursuant to the applicable law of the State of Delaware, which certificate is referred to as a “preferred stock designation,” to establish from time to time the number of shares to be included in each such series, and to fix the designation, powers, preferences, and rights, including voting rights and rights upon any liquidation of the Company, of the shares of each such series and any qualifications, limitations or restrictions thereof. The number of authorized shares of preferred stock may be increased or decreased (but not below the number of shares of preferred stock then outstanding) by the affirmative vote of the holders of a majority of the voting power of all of the then-outstanding shares of capital stock of the Company entitled to vote thereon, without a separate class vote of the holders of the preferred stock, or of any series thereof, unless a vote of any such holders is required pursuant to the terms of any preferred stock designation.

Common Stock

The shares of Company common stock to be issued in the mergers have been duly authorized and validly issued and will be fully paid and non-assessable. Except as otherwise required by applicable law and subject to the rights of the holders of any series of preferred stock, each registered holder of common stock will be entitled to one vote for each share of common stock held by such holder on each matter properly submitted to the stockholders of the Company for their vote; provided, however, that, except as otherwise required by applicable law, holders of common stock of the Company will not be entitled to vote on any amendment to the restated certificate of

incorporation of the Company (including any preferred stock designation) that relates solely to the terms of one or more outstanding series of preferred stock if the holders of that affected series of preferred stock are entitled, either separately or together as a class with the holders of one or more other series of preferred stock, to vote thereon by law or pursuant to the Company’s restated certificate of incorporation (including any preferred stock designation). The number of authorized shares of common stock may be increased or decreased (but not below the number of shares of common stock then outstanding) by the affirmative vote of the holders of a majority of the voting power of all of the then-outstanding shares of capital stock of the Company entitled to vote thereon, without a separate class vote of the holders of the common stock.

The Company does not have a classified board of directors nor does it permit cumulative voting. Holders of Company common stock are not entitled to any sinking fund provisions or preemptive rights to subscribe for additional shares of Company common stock, nor are they liable to further capital calls or to assessments by the Company.

Subject to any preferential rights with respect to any series of outstanding preferred stock and any restrictions that may be imposed by instruments governing any indebtedness of the Company or its subsidiaries, holders of Company common stock are entitled to receive dividends when and as declared by the board of directors of the Company at its discretion out of legally available funds. On liquidation, dissolution, sale or winding up of the Company, holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities and satisfaction of preferential rights.

Provisions that Have or May Have the Effect of Delaying or Prohibiting a Change in Control

Under the Company’s restated certificate of incorporation, the board of directors of the Company has the full authority permitted by Delaware law to determine the voting rights, if any, and designations, preferences, limitations and special rights of any series of the preferred stock. The issuance of preferred stock could adversely affect the voting power of holders of Company common stock and restrict their rights to receive payments upon liquidation of the Company. Further, the Company’s restated certificate of incorporation provides that a director may be removed from office with or without cause. Subject to applicable law, however, if the board of directors were to establish a series of preferred stock and provide that series with the right to elect a director in the preferred stock designation, that director could be removed without cause only by the holders of a majority of the shares of that series of preferred stock.

The Company’s restated certificate of incorporation provides that any action required or permitted to be taken by the stockholders must be effected at a duly called annual or special meeting and may not be taken by written consent.

The bylaws of the Company further provide that special meetings of the stockholders of the Company may be called only by the Chairman of the board of directors of the Company, the President of the Company or the board of directors of the Company acting pursuant to a resolution adopted by a majority of the total number of authorized directors on the board of directors of the Company (regardless of whether there exist any vacancies in the authorized directorships). Stockholders are not entitled to call special meetings of the stockholders of the Company.

The provisions of the Company’s restated certificate of incorporation and bylaws (1) conferring on the Company’s board of directors the full authority to issue preferred stock, (2) limiting the right to remove a director elected by the holders of any series of preferred stock, (3) requiring that stockholders act at a duly called meeting and (4) prohibiting stockholders from calling a special meeting, in certain instances could have the effect of delaying, deferring or preventing a change in control of the Company or the removal of existing management.

Limitation on Directors’ and Officers’ Liability

The restated certificate of incorporation of the Company provides that a director of the Company will not be personally liable to the Company or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for any of the following:

	•		any breach of the director’s duty of loyalty to the Company or its stockholders,

	•		acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law,

	•		payments of unlawful dividends or unlawful stock repurchases or redemptions, or

	•		any transaction from which the director derived an improper personal benefit.

The Company’s restated certificate of incorporation further provides that if the Delaware General Corporation Law (the “DGCL”) is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Company will be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. Any repeal or modification of the limitation of the directors’ liability to the Company by the stockholders of the Company will not adversely affect any right or protection of a director of the Company existing at the time of such repeal or modification. The Company’s restated certificate of incorporation and bylaws also provide that the Company will indemnify and advance expenses to its officers and directors to the fullest extent permitted by applicable law. The inclusion of these provisions in the Company’s restated certificate of incorporation and amended and restated bylaws may have the effect of reducing the likelihood of derivative litigation against directors and may discourage or deter shareholders or management from bringing a lawsuit against directors for breach of their fiduciary duty as a director, even though such an action, if successful, might otherwise have benefited the Company and the holders of Company common stock.

AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”) dated as of February 5, 2007, is by and among Hanover Compressor Company, a Delaware corporation (“Hanover”), Universal Compression Holdings, Inc., a Delaware corporation (“Universal”), Iliad Holdings, Inc., a Delaware corporation (“Holdco”), Hector Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Holdco (“Hanover Merger Sub”), and Ulysses Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Holdco (“Universal Merger Sub” and, together with Hanover Merger Sub, the “Merger Subs”).

RECITALS

A. The Mergers. The parties intend to effect the merger transactions described in Sections 1.1 and 1.2 so that thereafter each of Hanover and Universal will be wholly owned by Holdco.

B. Intended U.S. Federal Income Tax Consequences. The parties to this Agreement intend that pursuant to the applicable provisions of the Internal Revenue Code of 1986, as amended (the “Code”), neither gain nor loss shall be recognized for U. S. federal income tax purposes by a holder of Hanover Common Stock upon its transfer of Hanover Common Stock to Holdco in exchange for Holdco Common Stock pursuant to the Hanover Merger or by a holder of Universal Common Stock upon its transfer of Universal Common Stock to Holdco in exchange for Holdco Common Stock pursuant to the Universal Merger, except for gain that is recognized with respect to cash received in lieu of a fractional share of Holdco Common Stock.

NOW, THEREFORE, in consideration of the foregoing, and of the representations, warranties, covenants and agreements contained herein, the parties hereto hereby agree as follows:

ARTICLE 1

THE MERGERS

Section 1.1 The Universal Merger .

(a) Upon the terms and subject to the conditions set forth in this Agreement, at the Initial Effective Time, Universal Merger Sub shall be merged with and into Universal (the “Universal Merger”) in accordance with this Agreement, and the separate corporate existence of Universal Merger Sub shall thereupon cease. Universal shall be the surviving entity in the Universal Merger (sometimes referred to herein as the “Universal Surviving Entity”). The Universal Merger shall have the effects specified herein and in the General Corporation Law of the State of Delaware (the “DGCL”). As a result of the Universal Merger, the Universal Surviving Entity shall become a wholly owned Subsidiary of Holdco.

Prior to the Initial Effective Time, Holdco and Universal shall take all actions (if any) as may be required to permit the assumption of such Universal Options by Holdco pursuant to this Section 4.1(d) so that at the Initial Effective Time, the Universal Stock Plans (other than the Universal ESPP) shall be assumed by Holdco (with such adjustments thereto as may be required to reflect the Universal Merger, including the substitution of Holdco Common Stock for Universal Common Stock thereunder) and the Universal Options (other than the Universal Options granted under the Universal ESPP) shall be assumed and adjusted by Holdco, subject to the same terms and conditions as under the applicable Universal Stock Plan and the applicable option agreement entered into pursuant thereto, except that immediately following the Initial Effective Time (A) each such Universal Option shall be exercisable only for that whole number of shares of Holdco Common Stock equal to the product (rounded to the nearest whole share) of the number of shares of Universal Common Stock subject to such Universal Option immediately prior to the Initial Effective Time multiplied by the Universal Exchange Ratio, and (B) the exercise price per share of Holdco Common Stock shall be an amount equal to the exercise price per share of Universal Common Stock subject to such Universal Option in effect immediately prior to the Initial Effective Time divided by the Universal Exchange Ratio (the price per share, as so determined, being rounded down to the

nearest whole cent); provided, that in no event shall the exercise price be less than the par value of Holdco Common Stock. The adjustments provided in this paragraph with respect to any Universal Options that are “incentive stock options” as defined in Section 422 of the Code shall be and are intended to be effected in a manner which is consistent with Section 424(a) of the Code. Prior to the Initial Effective Time, Universal shall take all actions as may be required to terminate the Universal ESPP and all outstanding Universal Options thereunder effective immediately prior to the Initial Effective Time in accordance with the terms of Section 8.01 of the Universal ESPP. From and after the date of this Agreement, Universal and its Subsidiaries shall take no action to provide for the acceleration of the exercisability of any Universal Options in connection with the Universal Merger (except to the extent such acceleration is required under the terms of such Universal Options or change in control agreement as of the date of this Agreement). To the extent such acceleration is required under the terms of such Universal Options or other awards made under the Universal Stock Plans upon the occurrence of a change of control (as such term is defined in the applicable Universal Stock Plan or change in control agreement), Universal shall, prior to the Initial Effective Time, take all actions (if any) as may be required to cause such acceleration to occur at the Initial Effective Time and immediately prior to the assumption of the Universal Stock Plan by Holdco (to the extent permitted under the terms of such Universal Stock Plan as of the date of this Agreement). Prior to the Closing, Holdco shall file with the Securities and Exchange Commission (the “SEC”) a Registration Statement on Form S-8 (or any successor form) covering the shares of Holdco Common Stock issuable upon exercise of the Universal Options and other awards made under the Universal Stock Plans prior to the Initial Effective Time to be assumed pursuant to this paragraph and shall cause such registration statement to remain effective for as long as there are outstanding any such Universal Options. Except as otherwise specifically provided by this Section 4.1(d), the terms of the Universal Options and the relevant Universal Stock Plans, as in effect at the Initial Effective Time, shall remain in full force and effect with respect to the Universal Options after giving effect to the Universal Merger and the assumptions by Holdco as set forth above. As soon as practicable following the Initial Effective Time, Holdco shall deliver to the holders of Universal Options to be assumed pursuant to this paragraph appropriate notices setting forth such holders’ rights pursuant to the respective Universal Stock Plans and the agreements evidencing the grants of such Universal Options and stating that such Universal Options and such agreements shall be assumed by Holdco and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 4.1(d)).

(e) All options to acquire shares of Hanover Common Stock outstanding at the Effective Time identified in Section 4.1(e) of the Hanover Disclosure Letter and all options to acquire shares of Hanover Common Stock issued hereafter under Hanover’s equity plans (collectively, the “Hanover Stock Plans”) pursuant to Section 7.1(f) (individually, a “Hanover Option” and collectively, the “Hanover Options”) shall remain outstanding following the Effective Time, subject to the modifications described in this Section 4.1(e). Prior to the Effective Time, Holdco, Hanover and Universal shall take all actions (if any) as may be required to permit the assumption of such Hanover Options by Holdco pursuant to this Section 4.1(e) so that at the Effective Time, the Hanover Stock Plans shall be assumed by Holdco (with such adjustments thereto as may be required to reflect the Hanover Merger, including the substitution of Holdco Common Stock for Hanover Common Stock thereunder) and the Hanover Options shall be assumed and adjusted by Holdco, subject to the same terms and conditions as under the applicable Hanover Stock Plan and the applicable option agreement entered into pursuant

thereto, except that immediately following the Effective Time (A) each such Hanover Option shall be exercisable only for that whole number of shares of Holdco Common Stock equal to the product (rounded to the nearest whole share) of the number of shares of Hanover Common Stock subject to such Hanover Option immediately prior to the Effective Time multiplied by the Hanover Exchange Ratio, and (B) the exercise price per share of Holdco Common Stock shall be an amount equal to the exercise price per share of Hanover Common Stock subject to such Hanover Option in effect immediately prior to the Effective Time divided by the Hanover Exchange Ratio (the price per share, as so determined, being rounded down to the nearest whole cent); provided, that in no event shall the exercise price be less than the par value of Holdco Common Stock. The adjustments provided in this paragraph with respect to any Hanover Options that are “incentive stock options” as defined in Section 422 of the Code shall be and are intended to be effected in a manner which is consistent with Section 424(a) of the Code. From and after the date of this Agreement, Hanover and its Subsidiaries shall take no action to provide for the acceleration of the exercisability of any Hanover Options in connection with the Hanover Merger (except to the extent such acceleration is required under the terms of such Hanover Options as of the date of this Agreement). To the extent such acceleration is required under the terms of such Hanover Options or other awards made under the Hanover Stock Plans upon the occurrence of a change of control (as such term is defined in the applicable Hanover Stock Plan), prior to the Effective Time, Hanover shall take all actions (if any) as may be required to cause such acceleration to occur at the Effective Time and immediately prior to the assumption of the Hanover Stock Plan by Holdco (to the extent permitted under the terms of such Hanover Stock Plan as of the date of this Agreement). Prior to the Closing, Holdco shall file with the SEC a Registration Statement on Form S-8 (or any successor form) covering the shares of Holdco Common Stock issuable upon exercise of Hanover Options and other awards made under the Hanover Stock Plans prior to the Effective Time to be assumed pursuant to this paragraph and shall cause such registration statement to remain effective for as long as there are outstanding any such Hanover Options. Except as otherwise specifically provided by this Section 4.1(e), the terms of the Hanover Options and the relevant Hanover Stock Plans, as in effect at the Effective Time, shall remain in full force and effect with respect to Hanover Options after giving effect to the Hanover Merger and the assumptions by Holdco as set forth above. As soon as practicable following the Effective Time, Holdco shall deliver to the holders of Hanover Options appropriate notices setting forth such holders’ rights pursuant to the respective Hanover Stock Plans and the agreements evidencing the grants of such Hanover Options and stating that such Hanover Options and such agreements shall be assumed by Holdco and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 4.1(e)).

At or

prior to the Effective Time, Hanover and Holdco shall comply with all the provisions of the indentures governing the Convertible Notes relating to the assumption of the obligations under such indentures arising from the Hanover Merger.

Section 4.2 Exchange of Certificates Representing Hanover Common Stock and Universal Common Stock .

(a) Prior to the Initial Effective Time, Holdco shall appoint a bank or trust company reasonably satisfactory to Hanover to act as exchange agent (the “Exchange Agent”). Holdco shall, when and as needed, deposit, or cause to be deposited with the Exchange Agent, for the benefit of the holders of shares of Hanover Common Stock and Universal Common Stock for exchange in accordance with this Article 4, certificates representing the shares of Holdco Common Stock to be issued pursuant to Section 4.1 and delivered pursuant to this Section 4.2 in exchange for outstanding shares of Hanover Common Stock and Universal Common Stock, respectively. When and as needed, Holdco shall provide the Exchange Agent immediately following the Effective Time cash sufficient to pay cash in lieu of fractional shares of Holdco Common Stock in accordance with Section 4.2(e) (such cash and certificates for shares of Holdco Common Stock, together with any dividends or distributions with respect thereto, being hereinafter referred to as the “Exchange Fund”).

(b) Promptly after the Effective Time, Holdco shall cause the Exchange Agent to mail to each holder of record of one or more certificates (“Certificates”) that immediately prior to the Initial Effective Time or the Effective Time, as applicable, represented shares of Hanover Common Stock or Universal Common Stock: (A) a letter of transmittal (the “Letter of Transmittal”), which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Holdco may reasonably specify and (B) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of Holdco Common Stock, any unpaid dividends and distributions on shares of Holdco Common Stock in accordance with Section 4.2(c) and cash in lieu of fractional shares in accordance with Section 4.2(e). Upon surrender of a Certificate for cancellation to the Exchange Agent together with such Letter of Transmittal, duly executed and completed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefor (x) a certificate representing that number of whole shares of Holdco Common Stock and (y) a check representing the amount of cash in lieu of fractional shares, if any, and unpaid dividends and distributions, if any, which such holder has the right to receive pursuant to the provisions of this Article 4, after giving effect to any required withholding tax, and the Certificate so surrendered shall forthwith be canceled. No interest will be paid or accrued on the cash in lieu of fractional shares and unpaid dividends and distributions, if any, payable to holders of Certificates. In the event of a transfer of ownership of Hanover Common Stock that is not registered in the transfer records of Hanover or a transfer of ownership of Universal Common Stock that is not registered in the transfer records of Universal, a certificate representing the proper number of shares of Holdco Common Stock, together with a check for the cash to be paid in lieu of fractional shares, may be issued to such a transferee if the Certificate representing such Hanover Common Stock or Universal Common Stock, as the case may be, is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid.

(c) Notwithstanding any other provisions of this Agreement, no dividends or other distributions declared or made after the Effective Time with respect to shares of Holdco Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Holdco Common Stock issuable upon surrender of such Certificate as a result of the conversion provided in this Article 4 until such Certificate is surrendered as provided herein. Subject to the effect of Applicable Laws, following surrender of any such Certificate, there shall be paid to the holder of the Certificate so surrendered, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date prior to surrender payable with respect to the number of whole shares of Holdco Common Stock issued pursuant to Section 4.1, less the amount of any withholding taxes, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Holdco Common Stock, less the amount of any withholding taxes.

(d) (i) At or after the Effective Time, the Hanover Surviving Entity shall pay from funds on hand at the Effective Time any dividends or make other distributions with a record date prior to the Effective Time that may have been declared or made by Hanover on shares of Hanover Common Stock which remain unpaid at the Effective Time, and after the Effective Time, there shall be no transfers on the stock transfer books of the Hanover Surviving Entity of the shares of Hanover Common Stock which were outstanding immediately prior to the Effective Time and (ii) at or after the Initial Effective Time, the Universal Surviving Entity shall pay from funds on hand at the Initial Effective Time any dividends or make other distributions with a record date prior to the Initial Effective Time that may have been declared or made by Universal on shares of Universal Common Stock which remain unpaid at the Initial Effective Time, and after the Initial Effective Time, there shall be no transfers on the stock transfer books of the Universal Surviving Entity of the shares of Universal Common Stock which were outstanding immediately prior to the Initial Effective Time. If, after the Effective Time, Certificates are presented to Holdco, the presented Certificates shall be canceled and exchanged for certificates representing shares of Holdco Common Stock and cash in lieu of fractional shares, if any, deliverable in respect thereof pursuant to this Agreement in accordance with the procedures set forth in this Article 4. Certificates surrendered for exchange by any person constituting an “affiliate” of Hanover or Universal for purposes of Rule 145(c) under the Securities Act of 1933 (the “Securities Act”), shall not be exchanged until Hanover or Universal, as applicable, has received a written agreement from such person as provided in Section 7.11.

(e) No fractional shares of Holdco Common Stock shall be issued pursuant hereto. In lieu of the issuance of any fractional shares of Holdco Common Stock pursuant to Section 4.1(b), cash adjustments will be paid to holders in respect of any fractional shares of Holdco Common Stock that would otherwise be issuable, and the amount of such cash adjustment shall be equal to such fractional proportion of the Average Price of Universal Common Stock multiplied by the Hanover Exchange Ratio. “Average Price” means the average closing price of the Universal Common Stock, as such price is reported on the New York Stock Exchange as reported by Bloomberg Financial Markets or such other source as the parties shall agree in writing, for the 15 trading days ending on the third trading day immediately preceding the Initial Effective Time.

(f) Any portion of the Exchange Fund (including the proceeds of any investments thereof and any certificates for shares of Holdco Common Stock) that remains undistributed to the former stockholders of Hanover or Universal one year after the Effective Time shall be delivered to Holdco. Any former stockholders of Hanover or Universal who have not theretofore complied with this Article 4 shall thereafter look only to Holdco for delivery of certificates representing their shares of Holdco Common Stock and cash in lieu of fractional shares and for any unpaid dividends and distributions on the shares of Holdco Common Stock deliverable to such former stockholder pursuant to this Agreement.

(g) None of Holdco, Universal, Hanover, either Surviving Entity, the Exchange Agent or any other person shall be liable to any person for any portion of the Exchange Fund properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(h) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Holdco, the posting by such person of a bond in such reasonable amount as Holdco may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate certificates representing the shares of Holdco Common Stock, cash in lieu of fractional shares and unpaid dividends and distributions on shares of Holdco Common Stock, as provided in Section 4.2(c), deliverable in respect thereof pursuant to this Agreement.

Section 4.3 Adjustment of Exchange Ratios . If, between the date of this Agreement and the Initial Effective Time (in the case of the Universal Common Stock) or the Effective Time (in the case of the Hanover Common Stock) (and in each case, and as permitted by Section 7.l), the outstanding shares of Universal Common Stock or the outstanding shares of Hanover Common Stock shall have been increased, decreased, changed into or exchanged for a different number of shares or different class, in each case, by reason of any reclassification, recapitalization, stock split, split-up, combination or exchange of shares or a stock dividend or dividend payable in other securities shall be declared with a record date within such period, or any similar event shall have occurred, the applicable Universal Exchange Ratio or Hanover Exchange Ratio shall be appropriately adjusted to provide to the holders of Universal Common Stock or Hanover Common Stock, as the case may be, the same economic effect as contemplated by this Agreement prior to such event.

Section 4.4 Rule 16b-3 Approval . Prior to the Closing, Holdco, Hanover and Universal, and their respective Boards of Directors or committees thereof, shall use their reasonable best efforts to take all actions to cause any dispositions of Hanover Common Stock or Universal Common Stock (including derivative securities with respect to Hanover Common Stock or Universal Common Stock) or acquisitions of Holdco Common Stock (including derivative securities with respect to Holdco Common Stock) resulting from the transactions contemplated hereby by each individual who is subject to the reporting requirements of Section 16(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) to be exempt from Section 16(b) of the Exchange Act under Rule 16b-3 promulgated under the Exchange Act in accordance with the terms and conditions set forth in no-action letters issued by the SEC in similar transactions.

Hanover is duly qualified to do business and, to the extent such concept or a similar concept exists in the relevant jurisdiction, is in good standing under the laws of any jurisdiction in which the character of the properties owned or leased by it therein or in which the transaction of its business requires such qualification, except where the failure to be so qualified or in good standing, individually or in the aggregate, has not had and is not reasonably likely to have a Hanover Material Adverse Effect. Hanover has all requisite corporate power and authority to own, operate and lease its properties and to carry on its business as now conducted. The copies of Hanover’s certificate of incorporation and bylaws previously made available to Universal are true and correct and contain all amendments as of the date of this Agreement.

Hanover has duly executed and delivered this Agreement. Assuming this Agreement constitutes the valid and legally binding obligation of the other parties hereto, this Agreement constitutes the valid and legally binding obligation of Hanover, enforceable against Hanover in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to creditors’ rights and general principles of equity. Assuming the accuracy of the representations and warranties set forth in Section 6.19, Hanover has taken all action necessary to render the restrictions set forth in Section 203 of the DGCL, and any other applicable takeover law restricting or purporting to restrict business combinations, inapplicable to this Agreement and the transactions contemplated hereby.

As of the date of this Agreement, except as set forth in this Section 5.3, there are no outstanding shares of capital stock and there are no options, warrants, calls, subscriptions, convertible securities or other rights, agreements or commitments which obligate Hanover or any of its Subsidiaries to issue, transfer, sell or register any shares of capital stock or other voting securities of Hanover or any of its Subsidiaries.

(c) This Agreement, the Mergers and the transactions contemplated hereby do not, and will not, upon consummation of such transactions in accordance with their terms, result in any “change of control” or similar event or circumstance under (i) the terms of any Hanover Material Contract or (ii) any contract or plan under which any employees, officers or directors of Hanover or any of its Subsidiaries are entitled to payments or benefits, which, in the case of either clause (i) or (ii), gives rise to rights or benefits not otherwise available absent such change of control or similar event and requires either a cash payment or an accounting charge in accordance with U.S. generally accepted accounting principles, or (iii) any material Hanover Permit.

Section 5.7 SEC Documents .

(a) Hanover and its Subsidiaries have filed with the SEC all documents (including exhibits and any amendments thereto) required to be so filed by them since September 30, 2003 pursuant to Sections 13(a), 14(a) and 15(d) of the Exchange Act, and have made available to Universal each registration statement, report, proxy statement or information statement (other than preliminary materials) they have so filed, each in the form (including exhibits and any amendments thereto) filed with the SEC (collectively, the “Hanover Reports”). As of its respective date, each Hanover Report (i) complied in all material respects with the applicable requirements of the Exchange Act and the rules and regulations thereunder and (ii) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading, except for any statements in any Hanover Report that have been modified by an amendment to such report filed with the SEC prior to the date hereof. Each of the consolidated balance sheets included in or incorporated by reference into the Hanover Reports (including related notes and schedules) complied as to form in all material respects with the applicable accounting requirements and the published rules and regulations of the SEC with respect thereto and fairly presents in all material respects the consolidated financial position of Hanover and its Subsidiaries (or such entities as indicated in such balance sheet) as of its date, and each of the consolidated statements of operations, cash flows and changes in stockholders’ equity included in or incorporated by reference into the Hanover Reports (including any related notes and schedules) fairly presents in all material respects the results of operations, cash flows or changes in stockholders’ equity, as the case may be, of Hanover and its

Subsidiaries (or such entities as indicated in such balance sheet) for the periods set forth therein (subject, in the case of unaudited statements, to (x) such exceptions as may be permitted by Form 10-Q of the SEC and (y) normal, recurring year-end audit adjustments which are not material in the aggregate), in each case in accordance with generally accepted accounting principles consistently applied during the periods involved, except as may be noted therein. Except as and to the extent set forth on the consolidated balance sheet of Hanover and its Subsidiaries included in the most recent Hanover Report filed prior to the date of this Agreement that includes such a balance sheet, including all notes thereto, as of the date of such balance sheet, neither Hanover nor any of its Subsidiaries has any liabilities or obligations of any nature (whether accrued, absolute, contingent or otherwise) that would be required to be reflected on, or reserved against in, a consolidated balance sheet of Hanover or in the notes thereto prepared in accordance with generally accepted accounting principles consistently applied, other than liabilities or obligations which, individually or in the aggregate, have not had and are not reasonably likely to have a Hanover Material Adverse Effect.

(b) Since September 30, 2003, the chief executive officer and chief financial officer of Hanover have made all certifications (without qualification or exceptions to the matters certified) required by the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), and the statements contained in any such certifications are complete and correct; neither Hanover nor its officers have received notice from any governmental authority questioning or challenging the accuracy, completeness, form or manner of filing or submission of such certification. Hanover maintains “disclosure controls and procedures” (as defined in Rule 13a-15(e) under the Exchange Act); such disclosure controls and procedures are effective to ensure that all material information concerning Hanover and its Subsidiaries is made known on a timely basis to the individuals responsible for preparing the Hanover Reports and other public disclosure and Hanover is otherwise in substantial compliance with all applicable effective provisions of the Sarbanes-Oxley Act and the applicable listing standards of the New York Stock Exchange. As of the date hereof, Hanover has no knowledge of any material weaknesses in the design or operation of its internal controls over financial reporting. There is no reason to believe that Hanover’s auditors and its Chief Executive Officer and Chief Financial Officer will not be able to give the certifications and attestations required pursuant to the rules and regulations adopted pursuant to Section 404 of the Sarbanes-Oxley Act in connection with the filing of Hanover’s Annual Report on Form 10-K for the fiscal year ended December 31, 2006.

No loan or extension of credit is maintained by Hanover or its Subsidiaries to which the second sentence of Section 13(k)(1) of the Exchange Act applies.

Section 5.8 Litigation . Except as described in the Hanover Reports filed prior to the date of this Agreement, there are no actions, suits or proceedings pending against Hanover or any of its Subsidiaries or, to Hanover’s knowledge, threatened against

Hanover or any of its Subsidiaries, at law or in equity or in any arbitration or similar proceedings, before or by any U.S. federal, state or non-U.S. court, commission, board, bureau, agency or instrumentality or any U.S. or non-U.S. arbitral or other dispute resolution body, that, individually or in the aggregate, have had or are reasonably likely to have a Hanover Material Adverse Effect.

Hanover has not engaged in any “listed transaction” within the meaning of Treasury Regulation Section 1.6011-4.

REPRESENTATIONS AND WARRANTIES
OF UNIVERSAL, HOLDCO AND MERGER SUBS

Except as set forth in the disclosure letter delivered to Hanover by Universal at or prior to the execution of this Agreement (the “Universal Disclosure Letter”) and making reference to the particular subsection of this Agreement to which exception is being taken (provided that any information set forth in one section or subsection of the Universal Disclosure Letter shall be deemed to apply to each other section or subsection thereof to which its relevance is reasonably apparent), Universal, Holdco and each Merger Sub, jointly and severally, represent and warrant to Hanover that:

Section 6.1 Existence; Good Standing; Corporate Authority .

Universal is duly qualified to do business and, to the extent such concept or a similar concept exists in the relevant jurisdiction, is in good standing under the laws of any jurisdiction in which the character of the properties owned or leased by it therein or in which the transaction of its business requires such qualification, except where the failure to be so qualified or in good standing, individually or in the aggregate, has not had and is not reasonably likely to have a Universal Material Adverse Effect. Each of Universal, Holdco and each Merger Sub has all requisite corporate power and authority to own, operate and lease its properties and to carry on its business as now conducted. The copies of the certificates of incorporation and bylaws of Universal, Holdco and each Merger Sub previously made available to Hanover are true and correct and contain all amendments as of the date of this Agreement.

Assuming the accuracy of the representations and warranties set forth in Section 5.19, Universal has taken all action necessary to render the restrictions set forth in Section 203 of the DGCL, and any other applicable takeover law restricting or purporting to restrict business combinations, inapplicable to this Agreement and the transactions contemplated hereby.

Section 6.3 Capitalization .

Section 6.7 SEC Documents .

(a) Universal and its Subsidiaries have filed with the SEC all documents (including exhibits and any amendments thereto) required to be so filed by them since September 30, 2003 pursuant to Sections 13(a), 14(a) and 15(d) of the Exchange Act, and have made available to Hanover each registration statement, report, proxy statement or information statement (other than preliminary materials) they have so filed, each in the form (including exhibits and any amendments thereto) filed with the SEC (collectively, the “Universal Reports”). As of its respective date, each Universal Report (i) complied in all material respects with the applicable requirements of the Exchange Act and the rules and regulations thereunder and (ii) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading, except for any statements in any Universal Report that have been modified by an amendment to such report filed with the SEC prior to the date hereof. Each of the consolidated balance sheets included in or incorporated by reference into the Universal Reports (including related notes and schedules) complied as to form in all material respects with the applicable accounting requirements and the published rules and regulations of the SEC with respect thereto and fairly presents in all material respects the consolidated financial position of Universal and its Subsidiaries (or such entities as indicated in such balance sheet) as of its date, and each of the consolidated statements of operations, cash flows and changes in stockholders’ equity included in or incorporated by reference into the Universal Reports (including any related notes and schedules) fairly presents in all material respects the results of operations, cash flows or changes in stockholders’ equity, as the case may be, of Universal and its Subsidiaries (or such entities as indicated in such balance sheet) for the periods set forth therein (subject, in the case of unaudited statements, to (x) such exceptions as may be permitted by Form 10-Q of the SEC and (y) normal, recurring year-end audit adjustments which are not material in the aggregate), in each case in accordance with generally accepted accounting principles consistently applied during the periods involved, except as may be noted therein. Except as and to the extent set forth on the consolidated balance sheet of Universal and its Subsidiaries included in the most recent Universal Report filed prior to the date of this Agreement that includes such a balance sheet, including all notes thereto, as of the date of such balance sheet, neither Universal nor any of its Subsidiaries has any liabilities or obligations of any nature (whether accrued, absolute, contingent or otherwise) that would be required to be reflected on, or reserved against in, a consolidated balance sheet of Universal or in the notes thereto prepared in accordance with generally accepted accounting principles consistently applied, other than liabilities or obligations which, individually or in the aggregate, have not had and are not reasonably likely to have a Universal Material Adverse Effect.

(b) Since September 30, 2003, the chief executive officer and chief financial officer of Universal have made all certifications (without qualification or exceptions to the matters certified) required by the Sarbanes-Oxley Act, and the statements contained in any such certifications are complete and correct; neither Universal nor its officers have received notice from any governmental authority questioning or challenging the accuracy, completeness, form or manner of filing or submission of such certification. Universal maintains “disclosure controls and procedures” (as defined in Rule 13a-15(e) under the Exchange Act); such disclosure controls and procedures are effective to ensure that all material information concerning Universal and its Subsidiaries is made known on a timely basis to the individuals responsible for preparing the

Universal Reports and other public disclosure and Universal is otherwise in substantial compliance with all applicable effective provisions of the Sarbanes-Oxley Act and the applicable listing standards of the New York Stock Exchange. As of the date hereof, Universal has no knowledge of any material weaknesses in the design or operation of its internal controls over financial reporting.

There are no past or present facts, conditions or circumstances that interfere with the conduct of any of their respective businesses in the manner now conducted or which interfere with continued compliance with any Environmental Law, except for any non-compliance or interference that, individually or in the aggregate, has not had and is not reasonably likely to have a Universal Material Adverse Effect.

(b) Except for such matters as, individually or in the aggregate, have not had and are not reasonably likely to have a Universal Material Adverse Effect, no judicial or administrative proceedings or governmental investigations are pending or, to the knowledge of Universal, threatened against Universal or its Subsidiaries that allege the violation of or seek to impose liability pursuant to any Environmental Law, and there are no past or present facts, conditions or circumstances at, on or arising out of, or otherwise associated with, any current (or, to the knowledge of Universal or its Subsidiaries, former) businesses, assets or properties of Universal or any Subsidiary of Universal, including but not limited to on-site or off-site disposal, release or spill of any Hazardous Materials which violate Environmental Law or are reasonably likely to give rise to (i) costs, expenses, liabilities or obligations for any cleanup, remediation, disposal or corrective action under any Environmental Law, (ii) claims arising for personal injury, property damage or damage to natural resources, or (iii) fines, penalties or injunctive relief.

Section 6.14 Intellectual Property . Universal and its Subsidiaries own or possess adequate licenses or other valid rights to use all patents, patent rights, know-how, trade secrets, trademarks, trademark rights and other proprietary information and other proprietary intellectual property rights used or held for use in connection with their respective businesses as currently being conducted, except where the failure to own or possess such licenses and other rights, individually or in the aggregate, has not had and is not reasonably likely to have a Universal Material Adverse Effect, and there are no assertions or claims challenging the validity of any of the foregoing that, individually or in the aggregate, have not had and are not reasonably likely to have a Universal Material Adverse Effect. The conduct of Universal’s and its Subsidiaries’ respective businesses as currently conducted does not conflict with any patents, patent rights, licenses, trademarks, trademark rights, trade names, trade name rights or copyrights of others, except for such conflicts that, individually or in the aggregate, have not had and are not reasonably likely to have a Universal Material Adverse Effect. There is no material infringement of any proprietary right owned by or licensed by or to Universal or any of its Subsidiaries, except for such infringements that, individually or in the aggregate, have not had and are not reasonably likely to have a Universal Material Adverse Effect.

(b) Except for such matters as, individually or in the aggregate, have not had and are not reasonably likely to have a Universal Material Adverse Effect, no event relating specifically to Universal or its Subsidiaries has occurred that could reasonably be expected, after the date of this Agreement, to result in an upward adjustment in premiums under any insurance policies they maintain. Excluding insurance policies that have expired and been replaced in the

Prior to the date of this Agreement, no event has occurred, including the failure by Universal or any Subsidiary of Universal to give any notice or information or by giving any inaccurate or erroneous notice or information, which materially limits or impairs the rights of Universal or any Subsidiary of Universal under any such excess liability or protection and indemnity insurance policies.

Section 6.17 No Brokers .

Section 6.18 Opinion of Financial Advisor and Board Approvals . The Board of Directors of Universal has received the opinion of Goldman, Sachs & Co. to the effect that, subject to the assumptions, qualifications and limitations relating to such opinion, the Universal Exchange Ratio is fair, from a financial point of view, to the holders of Universal Common Stock, it being agreed that none of Holdco, Hanover or Hanover Merger Sub has any rights with respect to such opinion. Universal’s Board of Directors, at a meeting duly called and held, (i) determined that this Agreement and the transactions contemplated hereby are advisable and in the best interests of the stockholders of Universal, (ii) approved this Agreement and the transactions contemplated hereby and (iii) recommended adoption of this Agreement by the stockholders of Universal.

Section 6.19 Hanover Stock Ownership . Neither Universal nor any of its Subsidiaries owns any shares of capital stock of Hanover or any other securities convertible into or otherwise exercisable to acquire shares of capital stock of Hanover. Universal is not an “interested stockholder” with respect to Hanover and Universal has not, within the last three years, been an “interested stockholder” with respect to Hanover.

Section 6.21 Certain Contracts .

(b) As of the date of this Agreement, each Universal Material Contract is in full force and effect, and Universal and each of its Subsidiaries have in all material respects performed all obligations required to be performed by them to date under each Universal Material Contract to which they are party, except where such failure to be in full force and effect or such failure to perform, individually or in the aggregate, has not had and is not reasonably likely to have a Universal Material Adverse Effect. Except for such matters as, individually or in the aggregate, have not had and are not reasonably likely to have a Universal Material Adverse Effect, neither Universal nor any of its Subsidiaries (x) knows of, or has received written notice of, any breach of or violation or default under (nor, to the knowledge of Universal, does there exist any condition which with the passage of time or the giving of notice or both would result in such a violation or default under) any Universal Material Contract or (y) has received written notice of the desire of the other party or parties to any such Universal Material Contract to exercise any rights such party has to cancel, terminate or repudiate such contract or exercise remedies thereunder. Each Universal Material Contract is enforceable by Universal or a Subsidiary of Universal in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to creditors’ rights and general principles of equity, except where such unenforceability does not constitute, individually or in the aggregate, a Universal Material Adverse Effect.

Section 6.24 Takeover Statutes; Rights Plans . Assuming the accuracy of the representations of Hanover in Section 5.19 hereof, the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby will not cause to be applicable to the Universal Merger any Takeover Statute. Each of Universal, Holdco and the Merger Subs does not have any preferred share purchase rights plan or similar rights plan in effect.

Section 6.25 Title, Ownership and Related Matters.

(a) Universal and its Subsidiaries have, free and clear of all Liens except for Permitted Liens and Liens, if any, created or permitted to be imposed by Hanover, defensible title to their respective inventory, equipment and other tangible and intangible property, including the natural gas compression and oil and natural gas production and processing equipment owned and/or operated by Universal or its Subsidiaries and related spare parts as may

be reduced by the consumption thereof, or increased through the replacement thereof or addition thereto, in the ordinary course of maintenance and operation of their respective businesses, in each case as necessary to permit Universal and its Subsidiaries to conduct their respective businesses as currently conducted.

(b) Each of Universal and its Subsidiaries has complied in all material respects with the terms of all material leases to which it is a party and under which it is in occupancy, and all leases to which Universal or any of its Subsidiaries is a party or under which it is in occupancy are in full force and effect. Each of Universal and its Subsidiaries enjoys peaceful and undisturbed possession of the properties or assets purported to be leased under its material leases.

Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in the preceding sentence by any Representative of Hanover or any of its Subsidiaries, whether or not such person is purporting to act on behalf of Hanover or any of its Subsidiaries or otherwise, shall be a breach of this Section 7.2 by Hanover. Hanover shall, and shall cause its Subsidiaries to, immediately cease and cause to be terminated all existing discussions or negotiations with any person conducted heretofore with respect to any Hanover

Takeover Proposal and request the prompt return or destruction of all confidential information previously furnished. Notwithstanding the foregoing, at any time prior to obtaining Hanover Stockholder Approval, in response to a bona fide written Hanover Takeover Proposal that the Board of Directors of Hanover determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) constitutes or is reasonably likely to lead to a Hanover Superior Proposal, and which Hanover Takeover Proposal was made after the date of this Agreement and did not otherwise result from a breach of this Section 7.2, Hanover may, if its Board of Directors determines in good faith (after consultation with outside counsel) that the failure to do so would be inconsistent with its fiduciary duties to the stockholders of Hanover under Applicable Laws, and subject to compliance with Section 7.2(c) and after giving Universal written notice of such determination, (x) furnish information with respect to Hanover and its Subsidiaries to the person making such Hanover Takeover Proposal (and its Representatives) pursuant to a customary confidentiality agreement not less restrictive of such person than the Confidentiality Agreement, provided that all such information has previously been provided to Universal or is provided to Universal prior to or substantially concurrently with the time it is provided to such person, and (y) participate in discussions or negotiations with the person making such Hanover Takeover Proposal (and its Representatives) regarding such Hanover Takeover Proposal.

The term “Hanover Takeover Proposal” means any inquiry, proposal or offer from any person relating to, or that could reasonably be expected to lead to, any direct or indirect acquisition or purchase, in one transaction or a series of transactions, of assets or businesses that constitute 20% or more of the revenues, net income or the assets of Hanover and its Subsidiaries, taken as a whole, or 20% or more of any class of equity securities of Hanover or any of its “significant subsidiaries” (as that term is defined in Item 1.02(w) of Regulation S-X), any tender offer or exchange offer that if consummated would result in any person beneficially owning 20% or more of any class of equity securities of Hanover or any of its significant subsidiaries, or any merger, consolidation, business combination, recapitalization, liquidation, dissolution, joint venture, binding share exchange or similar transaction involving Hanover or any of its Subsidiaries pursuant to which any person or the stockholders of any person would own 20% or more of any class of equity securities of Hanover or any of its significant subsidiaries or of any resulting parent company of Hanover, other than the transactions contemplated by this Agreement.

The term “Hanover Superior Proposal” means any bona fide proposal or offer made by a third party that if consummated would result in such person’s (or its stockholders’) owning, directly or indirectly, more than 50% of the shares of Hanover Common Stock then outstanding (or of the surviving entity in a merger or the direct or indirect parent of the surviving entity in a merger) or all or substantially all the assets of Hanover, which the Board of Directors of Hanover determines in good faith (after consultation with a financial advisor of nationally recognized reputation) to be (i) more favorable to the stockholders of Hanover from a financial point of view than the Hanover Merger (taking into account all the terms and conditions of such proposal and this Agreement (including any changes to the financial terms of this Agreement proposed by Universal in response to such offer or otherwise)) and (ii) reasonably capable of being

financed and completed, taking into account all financial, legal, regulatory, timing and other aspects of such proposal.

For purposes of the definitions of “Hanover Takeover Proposal” and “Hanover Superior Proposal,” the term “person” shall include any group within the meaning of Section 13(d) of the Exchange Act.

(b) Neither the Board of Directors of Hanover nor any committee thereof shall (i) (A) withdraw (or modify in a manner adverse to Universal), or propose to withdraw (or modify in a manner adverse to Universal), the approval, recommendation or declaration of advisability by such Board of Directors or any such committee thereof of this Agreement, the Hanover Merger or the other transactions contemplated by this Agreement, (B) recommend, adopt or approve, or propose to recommend, adopt or approve, any Hanover Takeover Proposal or (C) fail to reaffirm within a reasonable period of time upon request by Universal (publicly if so requested) its recommendation of this Agreement, the Hanover Merger and the other transactions contemplated by this Agreement (any such action or failure described in this clause (i) being referred to as a “Hanover Adverse Recommendation Change”) or (ii) approve or recommend, or propose to approve or recommend, or allow Hanover or any of its Subsidiaries to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement constituting or related to, or that is intended to or could reasonably be expected to lead to, any Hanover Takeover Proposal (other than a confidentiality agreement referred to in Section 7.2(a)). Notwithstanding the foregoing, at any time prior to obtaining Hanover Stockholder Approval, the Board of Directors of Hanover may make a Hanover Adverse Recommendation Change if such Board of Directors determines in good faith (after consultation with outside counsel) that the failure to do so would be inconsistent with its fiduciary duties to the stockholders of Hanover under Applicable Laws; provided, however, that no Hanover Adverse Recommendation Change may be made until after the fifth business day following Universal’s receipt of written notice (a “Hanover Notice of Adverse Recommendation”) from Hanover advising Universal that the Board of Directors of Hanover intends to make a Hanover Adverse Recommendation Change and specifying the terms and conditions of the Hanover Superior Proposal, if any, that is related to such Hanover Adverse Recommendation Change (it being understood and agreed that any amendment to the financial terms or any other material term of such Hanover Superior Proposal shall require a new Hanover Notice of Adverse Recommendation and a new five business day period). In determining whether to make a Hanover Adverse Recommendation Change, the Board of Directors of Hanover shall take into account any changes to the financial terms of this Agreement proposed by Universal in response to a Hanover Notice of Adverse Recommendation or otherwise.

(c) In addition to the obligations of Hanover set forth in paragraphs (a) and (b) of this Section 7.2, Hanover shall promptly (and in any event within one business day after receipt thereof) advise Universal orally and in writing of any Hanover Takeover Proposal or any inquiry with respect to or that could reasonably be expected to lead to any Hanover Takeover Proposal, the material terms and conditions of any such Hanover Takeover Proposal or inquiry (including any changes thereto) and the identity of the person making any such Hanover Takeover Proposal or inquiry. Hanover shall (i) keep Universal fully informed of the status and

material terms and conditions (including any change therein) of any such Hanover Takeover Proposal or inquiry and (ii) provide to Universal as soon as practicable after receipt or delivery thereof with copies of all correspondence and other written material sent or provided to Hanover or any of its Subsidiaries from any person that describes any of the material terms and conditions of any Hanover Takeover Proposal.

(d) Nothing contained in this Section 7.2 shall prohibit Hanover from (x) taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act or (y) making any required disclosure to the stockholders of Hanover if, in the good faith judgment of the Board of Directors of Hanover (after consultation with outside counsel) failure to so disclose would constitute a violation of Applicable Law or fiduciary duty; provided, however, that in no event shall Hanover or its Board of Directors or any committee thereof take, or agree or resolve to take, any action prohibited by Section 7.2(b).

Section 7.3 No Solicitation by Universal .

(a) Universal shall not, nor shall it authorize or permit any of its Subsidiaries or any of their respective directors, officers or employees or any Representative retained by it or any of its Subsidiaries to, directly or indirectly through another person, (i) solicit, initiate or knowingly encourage, or take any other action designed to, or which could reasonably be expected to, facilitate, any inquiry or the making of any proposal or offer that constitutes, or that could reasonably be expected to lead to, a Universal Takeover Proposal or (ii) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any person any confidential information in connection with, any Universal Takeover Proposal. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in the preceding sentence by any Representative of Universal or any of its Subsidiaries, whether or not such person is purporting to act on behalf of Universal or any of its Subsidiaries or otherwise, shall be a breach of this Section 7.3 by Universal. Universal shall, and shall cause its Subsidiaries to, immediately cease and cause to be terminated all existing discussions or negotiations with any person conducted heretofore with respect to any Universal Takeover Proposal and request the prompt return or destruction of all confidential information previously furnished. Notwithstanding the foregoing, at any time prior to obtaining Universal Stockholder Approval, in response to a bona fide written Universal Takeover Proposal that the Board of Directors of Universal determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) constitutes or is reasonably likely to lead to a Universal Superior Proposal, and which Universal Takeover Proposal was made after the date of this Agreement and did not otherwise result from a breach of this Section 7.3, Universal may, if its Board of Directors determines in good faith (after consultation with outside counsel) that the failure to do so would be inconsistent with its fiduciary duties to the stockholders of Universal under Applicable Laws, and subject to compliance with Section 7.3(c) and after giving Hanover written notice of such determination, (x) furnish information with respect to Universal and its Subsidiaries to the person making such Universal Takeover Proposal (and its Representatives) pursuant to a customary confidentiality agreement not less restrictive of such person than the Confidentiality Agreement, provided that all such information has previously been provided to Hanover or is provided to Hanover prior to or substantially concurrently with the time it is provided to such person, and (y) participate in discussions or negotiations with the

person making such Universal Takeover Proposal (and its Representatives) regarding such Universal Takeover Proposal.

(b) a Hanover Adverse Recommendation Change shall have occurred.

Section 9.5 Effect of Termination.

(a) In the event that this Agreement is terminated by Universal pursuant to Section 9.4(b) and no Universal Material Adverse Effect shall have occurred after the date of this Agreement and be continuing at the time of the Hanover Adverse Recommendation Change giving rise to the termination by Universal, then Hanover shall pay Universal a fee equal to $70.0 million on the first business day following the date of termination of this Agreement.

(c) Each party acknowledges and agrees that the agreements contained in this Section 9.5 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other parties hereto would not enter into this Agreement; accordingly, if Hanover or Universal fails promptly to pay the amount due pursuant to this Section 9.5, and, in order to obtain such payment, the other party commences a suit that results in a judgment for a fee payable pursuant to this Section 9.5, such party shall also reimburse the other party’s costs and expenses (including attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of such fee from the date such payment was required to be made until the date of payment at the prime rate of Citibank, N.A. in effect on the date such payment was required to be made.

under this Agreement, at law or in equity, shall be preserved. The Confidentiality Agreement shall survive any termination of this Agreement, and the provisions of such Confidentiality Agreement shall apply to all information and material delivered by any party hereunder.

(e) For purposes of Sections 9.3, 9.4 and 9.5, the terms “Hanover Takeover Proposal” and “Universal Takeover Proposal” shall have the meanings assigned to such terms in Sections 7.2(a) and 7.3(a), respectively, except that all references to “20%” therein shall be deemed to be references to “40%.”

The shares of stock of the Company shall be represented by certificates of stock, signed in the name of the Company (a) by the President or a Vice President and (b) by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary, of the Company, certifying the number of shares of stock in the Company owned by the holder named in the certificate. Any or all of the signatures of such officers on the certificate may be facsimiles.

The Board of Directors of the Company (the “Board of Directors”) may direct a new certificate to be issued in place of any certificate theretofore issued by the Company alleged to have been lost, stolen or destroyed, upon the receipt of an affidavit of the fact by the person claiming the certificate of stock to be lost, stolen or destroyed. When authorizing such issuance of a new certificate, the Board of Directors may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate, or his legal representative, to give the Company a bond sufficient to indemnify it against any claim that may be made against the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate.

Section 1.4. Beneficial Owners . The Company shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends, and to vote as such owner, and to hold liable for calls and assessments a person registered on its books as the owner of shares, and shall not be bound to recognize any equitable or other claim to

or interest in such share or shares on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise provided by law.

Before payment of any dividend, there may be set aside out of any funds of the Company available for dividends such sum or sums as the Board of Directors from time to time, in its absolute discretion, deems proper as a reserve or reserves to meet contingencies, or for equalizing dividends, or for repairing or maintaining any property of the Company, or for any proper purpose, and the Board of Directors may modify or abolish any such reserve.

Such request shall state the purpose or purposes of the proposed meeting.

Whenever stockholders are required or permitted to take any action at a meeting, a written notice of the meeting shall be given which shall state the place, date and hour of the meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called.

A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A stockholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with the Secretary. Voting at meetings of stockholders need not be by written ballot and need not be conducted by inspectors of election unless so determined by the holders of shares of stock having a majority of the votes which could be cast by the holders of all outstanding shares of stock entitled to vote thereon which are present in person or by proxy at such meeting. At all meetings of stockholders for the election of directors, a plurality of the votes cast shall be sufficient to elect. All other elections and questions shall, unless otherwise provided by law, the Certificate of Incorporation or these Bylaws, be decided by the vote of the holders of shares of stock having a majority of the votes which could be cast by the holders of all shares of stock entitled to vote thereon which are present in person or represented by proxy at the meeting.

Section 2.9. Adjournments . Any meeting of stockholders, annual or special, may adjourn from time to time to reconvene at the same or some other place, and notice need not be given of any such adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken.

The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder of the Company who is present.

Section 2.11. Stock Ledger . The stock ledger of the Company shall be the only evidence as to which stockholders are entitled (a) to vote in person or by proxy at any meeting of stockholders, or (b) to examine either the stock ledger, the list required by Section 2.10 or the books of the Company.

Section 3.6. Quorum; Vote Required for Action . Except as may be otherwise specifically provided by law, the Certificate of Incorporation or these Bylaws, at all meetings of the Board of Directors a majority of the whole Board of Directors shall constitute a quorum for the transaction of business. The vote of a majority of the directors present at any meeting of the Board of Directors at which there is a quorum present shall be the act of the Board of Directors. If a quorum shall not be present at any meeting of the Board of Directors, the directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

Section 3.7. Organization . Meetings of the Board of Directors shall be presided over by the President, or in the President’s absence, by a chairman chosen at the meeting.

Section 3.8. Actions of the Board by Consent in Lieu of Meeting . Unless otherwise restricted by law, the Certificate of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may

Section 3.9. Committees . The Board of Directors may, by resolution passed by a majority of the whole Board of Directors, designate one or more committees, each committee to consist of one or more of the directors of the Company. The Board of Directors may designate one or more of the directors of the Company to sit on any such committee. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or disqualification of a member of the committee, and in the absence of a designation by the Board of Directors of an alternate member to replace the absent or disqualified member, the member or members thereof present at any meeting and not disqualified from voting, whether or not he or they constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in place of any absent or disqualified member. Any committee, to the extent permitted by law and to the extent provided in the resolution of the Board of Directors establishing such committee, shall have and may exercise all the powers and authority of the Board of Directors in the management of the business and affairs of the Company, and may authorize the seal of the Company to be affixed to all papers which may require it. Each committee shall keep regular minutes and report to the Board of Directors when required.

The designation of any such committee and the delegation thereto of authority shall not operate to relieve the Board of Directors, or any member thereof, of any responsibility imposed upon it or him by law, nor shall such committee function where action of the Board of Directors is required under applicable law. The Board of Directors shall have the power at any time to change the membership of any such committee and to fill vacancies in it. A majority of the members of any such committee shall constitute a quorum. Each such committee may elect a chairman and appoint such subcommittees and assistants as it may deem necessary.

Any member of any such committee elected or appointed by the Board of Directors may be removed by the Board of Directors whenever in its judgment the best interests of the Company will be served thereby, but such removal shall be without prejudice to the contract rights, if any, of the person so removed. Election or appointment of a member of a committee shall not of itself create contract rights.

Section 3.10. Compensation and Reimbursement of Expenses . The directors shall receive such compensation for their services as shall be determined by the Board of Directors and may be paid their expenses, if any, of attendance at each meeting of the Board of Directors. No such reimbursement shall preclude any director from serving the Company in any other capacity and receiving compensation therefor.

INDEMNIFICATION

Section 5.1 Right to Indemnification . The Company shall indemnify and hold harmless each Indemnitee (as this and all other capitalized words not heretofore defined are defined in Section 5.13 hereof) to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended. The rights of an Indemnitee provided under the preceding sentence shall include, but not be limited to, the right to be indemnified to the fullest extent permitted by Section 145(b) of the DGCL in Proceedings by or in the right of the Company and to the fullest extent permitted by Section 145(a) of the DGCL in all other Proceedings.

-7-

Section 5.2 Expenses . If an Indemnitee is, by reason of his Corporate Status, a witness in or is a party to any Proceeding, and is successful on the merits or otherwise, he shall be indemnified against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. If the Indemnitee is a party to and is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to any Matter in such Proceeding, the Company shall indemnify the Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf relating to each such Matter. The termination of any Matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such Matter.

Section 5.3 Request for Indemnification . To obtain indemnification, an Indemnitee shall submit to the Secretary of the Company a written request with such information as is reasonably available to the Indemnitee regarding the basis for such claim for indemnification. The Secretary of the Company shall promptly advise the Board of Directors of such request. An Indemnitee shall be advanced Expenses, within 10 days after requesting them, to the fullest extent permitted by Section 145(e) of the DGCL.

Section 5.4 Determination of Indemnification . The Indemnitee’s entitlement to indemnification shall be determined in accordance with Section 145(d) of the DGCL. If entitlement to indemnification is to be determined by Independent Counsel, the Company shall furnish notice to the Indemnitee within 10 days after receipt of the request for indemnification, specifying the identity and address of the Independent Counsel. The Indemnitee may, within fourteen days after receipt of such written notice of selection, deliver to the Company a written objection to such selection. Such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of Independent Counsel and the objection shall set forth with particularity the factual basis of such assertion. If there is an objection to the selection of Independent Counsel, either the Company or the Indemnitee may petition the Court of Chancery of the State of Delaware or any other court of competent jurisdiction for a determination that the objection is without a reasonable basis and/or for the appointment of Independent Counsel selected by the Court.

Except in the event that the determination of entitlement to indemnification is to be made by Independent Counsel, if the person or persons empowered under this Section 5.4 to determine entitlement to indemnification shall not have made and furnished to the Indemnitee in writing a determination of whether the Indemnitee is entitled to indemnification within 30 days after receipt by the Company of the Indemnitee’s request therefor, a determination of entitlement to indemnification shall be deemed to have been made, and the Indemnitee shall be entitled to such indemnification unless the Indemnitee knowingly misrepresented a material fact in connection with the request for indemnification or such indemnification is prohibited by law. The termination of any Proceeding or of any Matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Article) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company, or with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his conduct was unlawful.

-8-

Section 5.5 Payments to Independent Counsel . The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred acting pursuant to this Article and in any proceeding to which it is a party or witness in respect of its investigation and written report and shall pay all reasonable fees and expenses incident to the procedures in which such Independent Counsel was selected or appointed. No Independent Counsel may serve if a timely objection has been made to his selection until a court has determined that such objection is without a reasonable basis.

Section 5.6 Right to Bring Suit . In the event that (i) a determination is made pursuant to Section 5.4 hereof that the Indemnitee is not entitled to indemnification under this Article, (ii) advancement of Expenses is not timely made pursuant to Section 5.3 hereof, (iii) Independent Counsel has not made and delivered a written opinion determining the request for indemnification (a) within 90 days after being appointed by the court, or (b) within 90 days after objections to his selection have been overruled by the court, or (c) within 90 days after the time for the Company or the Indemnitee to object to his selection, or (iv) payment of indemnification is not made within five days after a determination of entitlement to indemnification, the Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other court of competent jurisdiction, of his entitlement to such indemnification or advancement of Expenses. In the event that a determination shall have been made that the Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 5.6 shall be conducted in all respects as a de novo trial on the merits and the Indemnitee shall not be prejudiced by reason of that adverse determination. If a determination shall have been made or deemed to have been made that the Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this Section 5.6, or otherwise, unless the Indemnitee knowingly misrepresented a material fact in connection with the request for indemnification, or such indemnification is prohibited by law.

The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to this Section 5.6 that the procedures and presumptions of this Article are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all provisions of this Article. In the event that the Indemnitee, pursuant to this Section 5.6, seeks a judicial adjudication to enforce his rights under, or to recover damages for breach of, this Article, the Indemnitee shall be entitled to recover from the Company, and shall be indemnified by the Company against, any and all Expenses actually and reasonably incurred by him in such judicial adjudication, but only if he prevails therein. If it shall be determined in such judicial adjudication that the Indemnitee is entitled to receive part but not all of the indemnification or advancement of Expenses sought, the Expenses incurred by the Indemnitee in connection with such judicial adjudication or arbitration shall be appropriately prorated.

Section 5.7 Non-Exclusivity of Rights . The rights to receive indemnification and advancement of Expenses as provided by this Article shall not be deemed exclusive of any other rights to which an Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of the stockholders or disinterested directors, or otherwise.

Section 5.8 Other Indemnification . The Company’s obligation, if any, to indemnify any Indemnitee who was or is serving at its request as a director, officer, employee, agent or fiduciary of another Company, partnership, joint venture, trust, employee benefit plan or other enterprise or nonprofit entity shall be reduced by any amount such Indemnitee may collect as indemnification from such other Company, partnership, joint venture, trust, employee benefit plan or other enterprise or nonprofit entity.

-2-

Corporation’s voting shares required under applicable law or these Bylaws to carry any such proposal, or, in the case of a nomination or nominations, have delivered a proxy statement and form of proxy to holders of a percentage of the Corporation’s voting shares reasonably believed by such stockholder or beneficial holder to be sufficient to elect the nominee or nominees proposed to be nominated by such stockholder, and must, in either case, have included in such materials the Solicitation Notice and (4) if no Solicitation Notice relating thereto has been timely provided pursuant to this Section, the stockholder or beneficial owner proposing such business or nomination must not have solicited a number of proxies sufficient to have required the delivery of such a Solicitation Notice under this Section.

Such stockholder’s notice shall set forth: (a) as to each person whom the stockholder proposes to nominate for election or reelection as a Director all information relating to such person that is required to be disclosed in solicitations of proxies for election of Directors, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), including such person’s written consent to being named in the proxy statement as a nominee and to serving as a Director if elected; (b) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; and (c) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (i) the name and address of such stockholder, as they appear on the Corporation’s books, and of such beneficial owner, (ii) the class and number of shares of the Corporation which are owned beneficially and of record by such stockholder and such beneficial owner, (iii) a representation that the stockholder is a holder of record of stock of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business and nomination and (iv) whether either such stockholder or beneficial owner intends to deliver a proxy statement and form of proxy to holders of, in the case of a proposal, at least the percentage of the Corporation’s voting shares required under applicable law to carry the proposal or, in the case of a nomination or nominations, a sufficient number of holders of the Corporation’s voting shares to elect such nominee or nominees (an affirmative statement of such intent, a “ Solicitation Notice ”).

(B) Special Meeting of Stockholders .

INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 8.1 Mandatory Indemnification of Directors and Officers . The Corporation shall indemnify and hold harmless to the full extent permitted by the laws of the State of Delaware as from time to time in effect any person who was or is a party or is threatened to be made a party to, or is otherwise involved in, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (whether or not an action by or in the right of the Corporation) (hereinafter a “ proceeding ”), by reason of the fact that he or she is or was a director or officer of the Corporation, or, while serving as a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (hereinafter an “ indemnitee ”), or by reason of any action alleged to have been taken or omitted in such capacity against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith; provided, however, that, except as provided in Section 8.2 with respect to proceedings to enforce rights to indemnification, the Corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board of Directors of the Corporation. The right to indemnification conferred by this Section 8.1 also shall include the right of such persons described in this Section 8.1 to be paid in advance by the Corporation for their expenses (including attorneys’ fees) incurred in defending any such proceeding in advance of its final disposition (hereinafter an “ advancement of expenses ”) to the full extent permitted by the laws of the State of Delaware, as from time to time in effect; provided, however , that, if the GCL requires, an advancement of expenses incurred by an indemnitee in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such indemnitee) shall be made only upon delivery to the Corporation of an undertaking (hereinafter an ‘‘ undertaking ”), by or on behalf of such indemnitee, to repay all amounts so

-9-

advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (hereinafter a “ final adjudication ”) that such indemnitee is not entitled to be indemnified for such expenses under this Section 8.1 or otherwise. The right to indemnification conferred on such persons by this Section 8.1 shall be a contract right.

Section 8.2 Right of Indemnitee to Bring Suit . If a claim under Section 8.1 of these Bylaws is not paid in full by the Corporation within sixty (60) days after a written claim has been received by the Corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be twenty (20) days, the indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the indemnitee shall be entitled to be paid also the expense of prosecuting or defending such suit. In (i) any suit brought by the indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (ii) in any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that, the indemnitee has not met any applicable standard for indemnification set forth in the GCL. Neither the failure of the Corporation (including its directors who are not parties to such action, a committee of such directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the indemnitee is proper in the circumstances because the indemnitee has met the applicable standard of conduct set forth in the GCL, nor an actual determination by the Corporation (including its directors who are not parties to such action, a committee of such directors, independent legal counsel, or its stockholders) that the indemnitee has not met such applicable standard of conduct, shall create a presumption that the indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the indemnitee, be a defense to such suit. In any suit brought by the indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Article VIII or otherwise shall be on the Corporation.

Section 8.3 Permissive Indemnification of Non-Officer Employees and Agents . The Corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (whether or not an action by or in the right of the Corporation) by reason of the fact that the person is or was an employee (other than an officer) or agent of the Corporation, or, while serving as an employee (other than an officer) or agent of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, to the extent (i) permitted by the laws of the State of Delaware as from time to time in effect, and (ii) authorized in the sole discretion of the Chief Executive Officer and at least one other of the following officers: the President, the Chief Financial Officer, or the General Counsel of the Corporation (the Chief Executive Officer and any of such other officers so authorizing such indemnification, the “ Authorizing Officers ”). The Corporation may, to the extent permitted by Delaware law and authorized in the sole discretion of the Authorizing Officers, pay expenses (including attorneys’ fees) reasonably incurred by any such employee or agent in defending any civil, criminal, administrative or investigative action, suit or proceeding in advance of the final disposition of such action, suit or proceeding, upon such terms and conditions as the Authorizing Officers authorizing such expense advancement determine in their sole discretion. The provisions of this Section 8.3 shall not constitute a contract right for any such employee or agent.

Section 8.4 General Provisions . The rights and authority conferred in any of the Sections of this Article VIII shall not be exclusive of any other right which any person seeking indemnification or advancement of expenses may have or hereafter acquire under any statute, provision of the Restated Certificate of Incorporation or these Bylaws, agreement, vote of stockholders or disinterested Directors or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office and shall continue as to a person who has ceased to be a Director, officer, employee or agent and shall inure to the

-10-

benefit of the heirs, executors and administrators of such a person. Neither the amendment or repeal of this Article VIII or any of the Sections thereof nor the adoption of any provision of the Restated Certificate of Incorporation or these Bylaws or of any statute inconsistent with this Article VIII or any of the Sections thereof shall eliminate or reduce the effect of this Article VIII or any of the Sections thereof in respect of any acts or omissions occurring prior to such amendment, repeal or adoption or an inconsistent provision.

ARTICLE IX
