5.2 Registration Rights.

(a) Piggyback Registration.

(i) If, at any time that any of the Registrable Securities (as defined below) are outstanding, the Company proposes to prepare and file with the Securities and Exchange Commission, or an equivalent foreign governmental authority (in the event that the Company proposes to register its securities on a foreign securities market) (in either event, the “Commission”) one or more registration statements or similar statements (except in connection with an initial public offering of its securities, subject to Section 5.2.(a)(iii) below) or post-effective amendments thereto covering equity securities of the Company, or any such securities of the Company held by its securityholders (in any such case, other than in connection with a merger, acquisition or pursuant to Form S-8 or successor form) (collectively, the “Registration Statement”) and such Registration Statement allows other securityholders of the Company to register their securities thereunder, the Company will give written notice of its intention to do so by registered mail (“Notice”), at least twenty (20) days prior to the initial filing of each such Registration Statement, to all holders of the Registrable Securities. Upon written request within ten (10) days after receipt of the Notice, a holder (a “Requesting Holder”) may request that the Company include any of the Requesting Holder’s Registrable Securities in the proposed Registration Statement, and the Company shall, as to each such Requesting Holder, use commercially reasonable best efforts to effect the registration under the Securities Act or any similar act, rule or regulation of any foreign governmental authority on which the Company’s securities are traded, of the Registrable Securities which it has been so requested to register (“Piggyback Registration”); provided, however, that if, in the written opinion of the Company’s managing underwriter, if any, for such offering, or the Company, the inclusion of all or a portion of the Registrable Securities requested to be registered, when added to the securities being registered by the Company or the selling securityholder(s), will exceed the maximum amount of the Company’s

securities which can be marketed (i) at a price reasonably related to their then current market value, or (ii) without otherwise materially adversely affecting the entire offering (an “Adverse Effect”), then the portion of the securities to be registered on behalf of all of the security holders of the Company who are entitled to participate in such registration (including holders of Registrable Securities), shall equal the number of shares which the Company is so advised can be sold in such offering without causing an Adverse Effect less the number of shares being sold by the Company and such shares included in such registration on behalf of the security holders of the Company shall be allocated pro rata among such holders requesting piggyback registration on the basis of the number of shares of Common Stock requested to be included in such registration by each such holder. The term “Registrable Securities” means (i) the Shares and (ii) any Common Stock of the Company issued as a dividend or other distribution with respect to, in exchange for or in replacement of the Shares; provided that any Shares or other shares of Common Stock shall not be considered Registrable Securities (y) at such time as all of the shares of Common Stock held by a holder may be freely traded (without limitation or restriction as to quantity or timing and without registration under the Securities Act or, if the Company’s securities are listed in a foreign jurisdiction, any act similar to the Securities Act) under Rule 144(k) promulgated under the Securities Act or otherwise under any foreign rule or regulation and (z) if such Shares or other shares of Common Sock have been previously sold pursuant to a registration under the Securities Act or a similar foreign rule or regulation.

(ii) If securities are proposed to be offered for sale pursuant to a Registration Statement by security holders of the Company (other than holders of Registrable Securities) and the total number of securities to be offered by such other selling security holders and the Requesting Holders is required to be reduced pursuant to a request from the managing underwriter or the Company (which request shall be made only for the reasons and in the manner set forth above) the aggregate number of Registrable Securities to be offered by Requesting Holders pursuant to such Registration Statement shall equal the number which bears the same ratio to the maximum number of securities that the underwriter or the Company believes may be included for all selling security holders as the number of Registrable Securities beneficially owned by the Requesting Holders bears to the total original number of securities proposed to be offered by the Requesting Holders and the other selling security holders.

(iii) Anything contained in this Section 5.2(a) to the contrary notwithstanding, the Company shall not be obligated to include any of the Requesting Holders’ Registrable Securities in a Registration Statement in connection with an initial public offering of its securities in the event that the Company does not include any securities of the Company held by any other security holder of the Company in such Registration Statement.

(b) Demand Registration.

(i) At any time six (6) months after the Company’s initial public offering pursuant to a firm commitment underwriting and prior to the fifth anniversary of the Company’s initial public offering, any “Majority Holder” (as defined below) of the

Registrable Securities shall have the right (which right is in addition to the piggyback registration rights provided for under Section 5.2(a) hereof), exercisable by written notice to the Company (the “Demand Registration Request”), to have the Company prepare and file with the Commission on three occasions, in the aggregate for all Majority Holders, a Registration Statement and such other documents, including a prospectus, as may be necessary (in the opinion of both counsel for the Company and counsel for such holder) in order to comply with the provisions of the Securities Act, so as to permit a public offering and sale of the Registrable Securities by the holder thereof; provided that the aggregate proceeds of such public offering are reasonably expected to exceed $10,000,000. The term “Majority Holder” as used in this Section 5.2(b) shall mean any holder or any combination of holders of Registrable Securities who hold a majority of the Registrable Securities not covered by a then-current Registration Statement.

(ii) The Company covenants and agrees to give written notice of any Demand Registration Request to all holders of Common Stock (including holders of Registrable Securities) and securities convertible into, or exchangeable for, Common Stock, within ten (10) days from the date of the Company’s receipt of any such Demand Registration Request. After receiving notice from the Company as provided in this Section 5.2(b), such holders may request the Company to include their shares of Common Stock in the Registration Statement to be filed pursuant to this Section 5.2(b) by notifying the Company of their decision to have such securities included within ten (10) days of their receipt of the Company’s notice; provided that a holder shall not be entitled to register shares of Common Stock if (y) all of the shares of Common Stock then held by such holder may be freely traded (without limitation or restriction as to quantity or timing and without registration under the Securities Act or, if the Company’s securities are listed in a foreign jurisdiction, any act similar to the Securities Act) under Rule 144(k) promulgated under the Securities Act or otherwise under any foreign rule or regulation and (z) if such shares of Common Sock have been previously sold pursuant to a registration statement under the Securities Act or a similar foreign rule or regulation.

(iii) If, in the written opinion of the Company’s managing underwriter, if any, or the Company, including in any registration pursuant to Section 5.2(b) the total number of shares of Common Stock requested to be registered by the Majority Holder and any other holder of Common Stock requesting registration of his or its shares of Common Stock will cause an Adverse Effect, then the shares of Common Stock to be included in such demand registration shall equal the number of shares which the Company is so advised or so determines can be sold in such offering without causing an Adverse Effect and such shares included in such registration shall be allocated pro rata among the holders (including the holders of Registrable Securities) requesting registration on the basis of the number of shares of Common Stock requested to be included in such registration by each such holder.

(iv) Notwithstanding the foregoing, if at any time of any request to register Registrable Shares pursuant to this Section 5.2(b), the Company (x) is engaged or has substantially developed plans to engage within 90 days of the time of the request, in a registered public offering as to which holders may include Registrable Shares pursuant to Section 5.2(a), (y) is engaged in any other activity which, in the good faith determination

of the Company’s Board of Directors, would be adversely affected by the requested registration to the material detriment of the Company or (z) the Company’s Board of Directors determines, in its good faith, that it is in the best interests of the Company not to disclose the existence of or facts surrounding a significant corporate development or transaction then pending or in progress, then the Company may at its option direct that such request be delayed for a period not in excess of the earlier of (i) 90 days from the date of such request in the event that such offering or such other material activity, as the case may be, has not commenced during such 90 day period, (ii) 180 days from the effective date of such offering, if applicable, (iii) 120 days from the date of commencement of such other material activity, if applicable, or (iv) such time that the Company is no longer in good faith actively and diligently pursuing such offering or such activity; provided that such right to delay a request may be exercised by the Company not more than twice in any 15 month period.

(c) The rights to cause the Company to register Registrable Securities pursuant to Section 5.2 may be assigned by holders thereof to any transferee of the Shares provided that (a) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to such registration rights are being assigned, (b) such assignment shall be effective only if immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Securities Act and (c) such rights may not be assigned to any person or entity which, in the Company’s reasonable judgment, is a competitor of the Company.

(d) Company Covenants in Connection with Registration.

(i) In connection with any registration under Section 5.2 hereof, the Company shall file the Registration Statement as expeditiously as possible, but in any event no later than sixty (60) days following receipt of any demand therefor, shall use its commercially reasonable best efforts to cause any such Registration Statement to be declared effective at the earliest possible time, and shall furnish each holder of Registrable Securities such number of prospectuses as shall reasonably be requested. Once effective, the Company shall maintain the effectiveness of the Registration Statement until the earlier of (i) the date that all of the Registrable Securities included in such offering have been sold, or (ii) one hundred and eighty days after the effectiveness of such Registration Statement.

(ii) The Company shall pay all costs, fees and expenses (other than underwriting fees, discounts and nonaccountable expense allowance applicable to the Registrable Securities) in connection with all Registration Statements filed pursuant to Sections 5.2(a) and 5.2(b) hereof including, without limitation, the Company’s legal and accounting fees, printing expenses, and blue sky fees and expenses and the fees and expenses of one counsel retained by the holders of Registrable Securities up to a maximum of $10,000.

(iii) The Company shall take all necessary action which may be required to (i) qualify or register the Registrable Securities included in the Registration Statement, for offering and sale under the securities or blue sky laws of such states as are

reasonably requested by the holders of such securities and (ii) list the Registrable Securities on the principal securities exchange (or the Nasdaq Stock Market) on which the Common Stock is so listed.

(iv) The Company shall indemnify and hold harmless the holders of the Registrable Securities, and each officer, director, employee and agent of the holders of the Registrable Securities, from and against any and all losses, claims, damages and liabilities, including attorney fees caused by any untrue statement of a material fact contained in any Registration Statement, any post-effective amendment to such Registration Statement, or any prospectus included therein required to be filed or furnished by reason of this Section 5.2 or caused by any omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission based upon information furnished or required to be furnished in writing to the Company by the holders of the Registrable Securities or underwriter within the meaning of the Securities Act and each officer, director, employee and agent of the holders of the Registrable Securities and underwriter.

(v) In connection with any Registration Statement in which a seller of Registrable Securities is participating, each such seller will furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the fullest extent permitted by law, each such seller will indemnify the Company and its directors and officers and each person who controls the Company (within the meaning of the Securities Act or the Exchange Act) against any and all losses, claims, damages, liabilities and expenses (including, without limitation, reasonable attorneys’ fees and disbursements) resulting from any untrue statement or alleged untrue statement of a material fact contained in the registration statement, prospectus or any preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission is contained in any information or affidavit so furnished in writing by such seller or any of its affiliates specifically for inclusion in the registration statement; provided that the obligation to indemnify will be several, not joint and several, among such sellers of Registrable Securities, and, provided, further, that such liability will be limited to, the net amount received by such seller from the sale of Registrable Securities pursuant to such registration statement.

(vi) If for any reason the indemnification provided for in this Section 5.2 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, claim, damage, liability or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect not only the relative benefits received by the indemnified party and the indemnifying party, but also the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations.

(vii) The Company shall promptly deliver copies of all correspondence between the Commission and the Company, its counsel or auditors and all memoranda relating to discussions with the Commission or its staff with respect to the Registration Statement to each holder of Registrable Securities included for such registration in such Registration Statement pursuant to Sections 5.2 hereof requesting such correspondence and memoranda and to the managing underwriter, if any, of the offering in connection with which such holder’s Registrable Securities are being registered and shall permit each holder of Registrable Securities and such underwriter to do such reasonable investigation, upon reasonable advance notice, with respect to information contained in or omitted from the Registration Statement as it deems reasonably necessary to comply with applicable securities laws or rules of NASD Regulation, Inc. Such investigation shall include access to books, records and properties and opportunities to discuss the business of the Company with its officers and independent auditors, all to such reasonable extent and at such reasonable times and as often as any such holder of Registrable Securities or underwriter shall reasonably request.

(viii) The Company shall use its reasonable best efforts to make available its employees and personnel for participation in “road shows” and other marketing efforts and otherwise provide reasonable assistance to the underwriters (taking into account the needs of the Company’s businesses and the requirements of the marketing process) in the marketing of Registrable Securities in any underwritten offering;

(e) It is expressly acknowledged and agreed that the holders of Common Stock of the Company are intended third party beneficiaries of Sections 5.2(b) and (c); provided, that in no event shall such third parties be entitled to consent to any amendment to this Section 5.2 (including amendments to Section 5.2(b) and (c)).

5.3 Restrictions on Transfer. Goldman agrees that it will not, sell, assign or transfer the Shares in violation of the Securities Act, or any other applicable state or foreign securities laws (“Other Securities Laws”) and understands that it cannot sell, assign or transfer the Shares unless the Shares are registered under the Securities Act and Other Securities Laws or an exemption from such registration is applicable to such transfer.

5.4 Holdback. In the event of any registration of shares of Common Stock in connection with an underwritten public offering, Goldman agrees not to effect any sale of any shares of Common Stock or any common stock equivalents (in each case, other than as part of such public offering) during the 14 days prior to the effective date of such registration statement (except as part of such registration statement) or during the period after such effective date as reasonably required by the managing underwriter of an underwritten offering, but in no event longer than the earlier of (i) the shortest period applicable to the officers, directors and stockholders (other than the holders of the Shares) holding 5% or more of the capital stock of the Company or (ii) 180 days.

5.5 Goldman Relationship.

(a) Between the date hereof and the date of the Company’s first public offering of equity securities, Goldman will have the exclusive right to act as financial advisor to the Company and its Subsidiaries.

(b) In the event that the Company or its Subsidiaries determines to undertake any public or private financing transactions prior to and including its initial public offering of equity securities, the Company agrees to offer Goldman the right of first offer and last refusal (as detailed in Section 5.5(c) below) to act in each such transaction as (i) lead underwriter, sole book-running lead manager or sole agent in the case of any offering or placement of securities and (ii) sole lead arranger and book-runner, sole syndication agent and administrative agent in the case of a senior syndicated bank loan or bridge loan. In the event that the Company or its Subsidiaries determines to seek third party project debt financing, the Company agrees to offer Goldman the right of first offer and last refusal (as detailed in Section 5.5(c) below) to provide any such debt. If Goldman agrees to act in such capacity, the Company and Goldman will enter into an appropriate form of agreement relating to the type of transaction involved and containing customary terms and conditions, including customary fee provisions and provisions relating to Xxxxxxx’x indemnity. In addition, the Company shall offer Goldman the right of first offer and last refusal (as detailed in Section 5.5(c) below) to act as sole principal or sole counterparty in the case of any foreign exchange or commodities transaction, currency or interest rate swap or other hedging transaction undertaken by the Company or its Subsidiaries prior to or in connection with its initial public offering of equity securities. Where Goldman agrees to act as the principal or counterparty in a swap, hedging or other transaction with the Company or its Subsidiaries, such transactions will be based on customary documentation for such transactions. The Company acknowledges that nothing herein is an express or an implied commitment by Goldman to act in any capacity in any such transaction, to provide financing or to purchase or place any securities, which commitment shall only be set forth in a separate agreement.

(c) In the event the Company or its Subsidiaries intends to undertake any of the transactions described in Section 5.5(b), the Company shall give Goldman written notice of such intention, describing the type of transaction and the general terms upon which the Company or its Subsidiaries proposes to effect such transaction. Goldman shall have twenty (20) days (unless a shorter period of time is agreed upon by Goldman) (the “Exclusive Negotiation Period”) after the giving of the notice by the Company to negotiate exclusively with the Company and its Subsidiaries to reach a written agreement setting forth the terms and conditions of Xxxxxxx’x participation in such transaction. If the Company and Goldman do not conclude the negotiation and execution of a written agreement regarding the transaction within the Exclusive Negotiation Period, then the Company and its Subsidiaries shall for the first 30-day period that follows the conclusion of the Exclusive Negotiation Period have the right to negotiate with one or more third parties regarding the transaction but only on terms and conditions which are more favorable to the Company and its Subsidiaries, taken as a whole, than those last offered to or by Goldman. The Company and its Subsidiaries shall not enter into any agreements with any such third parties unless it has first provided Goldman with all of the proposed terms and conditions thereof and at least five business days to accept such terms and conditions.

5.6 Expenses. Each party shall pay all of its own costs in connection with the preparation, negotiation and execution of this Agreement and the consummation of the transactions contemplated hereby; provided, however, the Company will pay all expenses (other than Xxxxxxx’x legal expenses and other than underwriting commissions and discounts) with respect to registration of securities under Section 5.2 hereof.

5.7 Anti-Dilution.

(a) In the event that the Company shall at any time or from time to time after the date hereof, issue, grant or sell any Additional Stock (as defined in Section 5.8(b), but for the purposes of this Section 5.7, such definition shall not include the items set forth in clause (i) of Section 5.8(b)) for a consideration, exercise or conversion price per share (as the case may be, the “Anti-Dilution Price”) less than the then current Effective Price (as defined below), then, in connection with such issuance, the Company shall issue to Goldman, without any additional consideration paid by Goldman, additional shares of Common Stock (such shares, the “Anti-Dilution Shares”) such that after the issuance of the Anti-Dilution Shares, the Effective Price of the shares of Common Stock owned by Goldman shall equal such Anti-Dilution Price.

“Effective Price” means the Purchase Price divided by the number of shares of Common Stock acquired at the Closing and/or pursuant to this Section 5.7. The initial Effective Price shall be $53.39 per share.

(b) The Company (and any successor corporation) shall take all action necessary so that a number of shares of the authorized but unissued Common Stock (or common stock in the case of any successor corporation) sufficient to provide for issuance of additional shares of Common Stock to Goldman in accordance with the provisions of Section 5.7(a) above are at all times reserved by the Company (or any successor corporation), free from preemptive rights, for such issuance.

(c) Whenever the Company shall take any of the actions specified in this Section 5.7 which would result in any adjustment in the Effective Price, the Company shall give notice to Goldman, which notice shall be made within 10 days after the effective date of such adjustment and shall state the adjustment and the Effective Price. Notwithstanding the foregoing notice provisions, failure by the Company to give such notice or a defect in such notice shall not affect the binding nature of such corporate action of the Company.

(d) For the purpose of any computation to be made in accordance with Section 5.7(a), the following provisions shall apply:

(i) In case of the issuance or sale of shares of Common Stock for a consideration part or all of which shall be cash, the amount of the cash consideration therefor shall be deemed to be the amount of cash received by the Company for such shares (or, if shares of Common Stock are offered by the Company for subscription, the subscription price, or, if such securities shall be sold to underwriters or dealers for public offering without a subscription offering, the initial public offering price) before deducting therefrom any compensation paid or discount allowed in the sale, underwriting or

purchase thereof by underwriters or dealers or others performing similar services, or any expenses incurred in connection therewith.

(ii) In the case of the issuance or sale (otherwise than as a dividend or other distribution on any stock of the Company) of shares of Common Stock for a consideration part or all of which shall be other than cash, the amount of the consideration therefor other than cash shall be deemed to be the fair market value of the consideration as determined in good faith by the Board of Directors of the Company plus the amount of cash, if any.

(iii) In the case of the issuance of options, rights, or warrants to purchase or subscribe for shares of Common Stock, securities convertible into or exchangeable for shares of Common Stock, or options, rights or warrants to purchase or subscribe for any such convertible or exchangeable securities, the following provisions shall apply:

(A) The effective price for the issuance, grant or sale of any options, rights or warrants shall be deemed to be the minimum purchase price per share provided for in such options, rights or warrants at the time of issuance plus the consideration, if any, received by the Company in connection with the sale or issuance of such options, rights or warrants; provided, however, that upon the termination of such options, rights or warrants, if any thereof shall not have been exercised, the Effective Price then in effect shall forthwith be readjusted and thereafter be the price which it would have been had such adjustment been made on the basis of the issuance only of shares of Common Stock actually issued or issuable upon the exercise of those options, rights or warrants as to which the exercise of rights shall not have expired or terminated unexercised.

(B) The effective price for the issuance, grant or sale of any convertible or exchangeable securities shall be deemed to be the consideration received by the Company in connection with the sale of such securities plus the consideration, if any, receivable by the Company upon the conversion or exchange thereof; provided, however, that upon the termination of the right to convert or exchange such convertible or exchangeable securities (whether by reason of redemption or otherwise), the Effective Price then in effect shall forthwith be readjusted and thereafter be the price which it would have been had such adjustment been made on the basis of the issuance only of shares actually issued or issuable upon the conversion or exchange of those convertible or exchangeable securities as to which the conversion or exchange rights shall not have expired or terminated unexercised.

(C) If any change shall occur in the price per share provided for in any of the options, rights or warrants referred to in Section 5.7(d)(iii)(A), or in the price per share at which the securities referred to in Section 5.7(d)(iii)(B) are convertible or exchangeable, such options, rights

or warrants or conversion or exchange rights, as the case may be, shall be deemed to have expired or terminated on the date when such price change became effective in respect of shares not theretofore issued pursuant to the exercise or conversion or exchange thereof, and the Company shall be deemed to have issued upon such date new options, rights or warrants or convertible or exchangeable securities at the new price in respect of the number of shares issuable upon the exercise of such options, rights or warrants or the conversion or exchange of such convertible or exchangeable securities.

(e) In case the Company shall pay or make a dividend or other distribution to all holders of its Common Stock in shares of Common Stock, the Effective Price in effect at the opening of business on the day following the date fixed for the determination of shareholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Effective Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination, and the denominator of which shall be the sum of the numerator and the total number of shares constituting such dividend or other distribution, such reduction to become effective immediately after the opening of business on the day next following the date fixed for such determination. For the purposes of this Section 5.7(e), the number of shares of Common Stock at any time outstanding shall not include shares of Common Stock held in the treasury of the Company.

(f) In case the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Effective Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and, conversely, in case the outstanding shares of Common Stock shall each be combined into a smaller number of shares of Common Stock, the Effective Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

(g) Anything contained in this Section 5.7 to the contrary notwithstanding, the rights granted under this Section 5.7 shall terminate and be of no further force or effect upon earlier of (i) the closing of a firm commitment underwritten public offering pursuant to an effective registration statement filed under the Securities Act covering the offer and sale of Common Stock for the account of the Company in which the per share price is based on a pre-offering valuation of the Company of not less than $60,000,000 or (ii) upon any merger, or consolidation of the Company with or into another entity where the stockholders of the Company immediately prior to such event hold less than a majority of the outstanding voting power of the surviving or consolidated entity, other than a merger for the sole purpose of effecting a reorganization or change in domicile of the Company.

5.8 Right of First Offer.

(a) Subject to the terms and conditions set forth below, from the date hereof until such time as the Company effectuates an offering of its Common Stock to the public,

Goldman shall have the right of first offer to purchase, on a pro rata basis, any Additional Stock which the Company may, from time to time, propose to issue and sell. Xxxxxxx’x pro rata share, for purposes of this right of first offer, shall be determined by dividing (x) the total number of shares of Common Stock which are owned by Goldman, by (y) the total number of shares of outstanding Common Stock on a fully-diluted basis. The failure by Goldman to exercise its right of first offer with respect to any particular issuance shall not affect in any way such right with respect to any subsequent issuance.

(b) The term “Additional Stock” shall mean Common Stock or options, warrants or other rights to acquire or securities convertible into or exchangeable for shares of Common Stock, including shares held in the Company’s treasury, but shall not include (i) securities offered to the public pursuant to a registration statement approved by the Board of Directors of the Company and filed with the Commission for a public offering and sale of securities of the Company, (ii) securities issued for the acquisition of another corporation or other entity by merger, purchase of all or substantially all of the assets of such other corporation or other entity or other reorganization resulting in the ownership by the Company of not less than 51% of the voting power of such other corporation or entity; provided that such transaction is approved by a majority of the disinterested directors of the Company, (iii) options to purchase up to 75,000 shares (as equitably adjusted for stock split, stock dividend, conversion or reclassification) of Common Stock pursuant to the Company’s 2002 Stock Option Plan and any options to purchase shares of Common Stock issued pursuant to the Company’s future stock option plans or similar plans approved by the Board of Directors and the stockholders of the Company, but only to the extent that not more than 15% of the options to purchase Common Stock subject to any one such plan are issued to any one person or entity (including his or its respective affiliates, as the case may be), (iv) securities issued as a result of any stock split, stock dividend, conversion or reclassification of Common Stock, distributable on a pro rata basis to all holders of Common Stock, (v) securities issued as a result of any stock split, stock dividend or reclassification of Series A Preferred Stock, (vi) securities issued to any unaffiliated and independent third party lenders pursuant to any bank financing arrangement approved by the Board of Directors (including any securities issued upon exercise of such securities), (vii) securities sold to stockholders of the Company pursuant to a general rights offering to all stockholders, offered on a pro rata basis, (viii) securities issuable upon exercise of options, warrants or other rights to acquire or securities convertible into or exchangeable for shares of Common Stock that are currently outstanding, (ix) securities issued to directors of the Company solely as compensation for service to the Company as a director up to a maximum of 10,000 shares of Common Stock (as equitably adjusted for stock split, stock dividend, conversion or reclassification) provided that Goldman or its designee on the Board of Directors, if any, shall receive an equivalent grant of securities, (x) securities issued upon exercise or conversion of any Additional Stock or (xi) securities issued in connection with any anti-dilution rights of any other stockholder of the Company.

(c) In the event the Company intends to issue any Additional Stock, it shall give Goldman written notice (“First Offer Notice”) of such intention, describing the type of Additional Stock to be issued, the price thereof and the general terms upon which the Company proposes to effect such issuance. Goldman shall have twenty (20) days (unless a shorter period of time is agreed upon by Goldman) from the date of any such First Offer Notice (the “Initial Exercise Period”) to agree to purchase its pro rata share of such Additional Stock for the

purchase price and upon the terms and conditions specified in the Company’s First Offer Notice by giving written notice to the Company stating the quantity of Additional Stock to be so purchased. In the event there is a material change in the terms upon which Additional Stock is offered by the Company following delivery of the First Offer Notice, the Company will issue a new First Offer Notice and Goldman will have the longer of (i) the remainder of the Initial Exercise Period or (ii) ten (10) days from the date of issuance of the new First Offer Notice to deliver a new notice of irrevocable acceptance to purchase the Additional Stock on the new terms specified in such new First Offer Notice.

(d) If Goldman does not elect to purchase all of the Additional Stock so offered, the Company shall have the right to sell the unsold Additional Stock to any third party within ninety (90) days after the date of the First Offer Notice at a purchase price not less than, and upon terms and conditions not more favorable than, the purchase price and terms and conditions set forth in the First Offer Notice. If the Company shall not sell all of the Additional Stock within such ninety (90) day period, such Additional Stock shall again be subject to the terms, conditions and restrictions set forth in this Section 5.8.

(e) For convenience in administration, the Company may offer and sell Additional Stock covered by the right provided in Section 5.8 without first offering such securities to Goldman, so long as Goldman is given prior notice of such sale and the opportunity to purchase its pro rata amount (which shall be calculated after giving effect to such issuance to Goldman of its pro rata amount) within twenty (20) days after the close of the sale of the Additional Stock.

5.9 Disclosure of Investment; Press Releases. The Company, on the one hand, and Goldman, on the other hand, agree that they will not, (a) except as may be necessary or desirable in connection with a request by a governmental agency, regulatory or supervisory authority, stock exchange or court or as required by law, and in the case of Goldman only, other than to affiliates of Goldman and employees of Goldman or its affiliates, publicly disclose the transactions contemplated by the Agreement or any of the terms hereof without the prior consent of Goldman, on the one hand, and the Company, on the other hand, or (b) use in advertising or publicity the name of any party hereto, or any partner or employee of such party hereto or any of its respective affiliates, or any trade name, trademark, trade device, service xxxx, symbol or any abbreviation, contraction or simulation thereof owned by the other party hereto or any of its respective affiliates, in either case without the prior written consent of such party; provided, however, that Goldman may describe the transactions contemplated hereby in any promotional literature prepared by or on behalf of Goldman. From and after the date hereof, neither the Company nor any of its Subsidiaries will represent, directly or indirectly, that any product or any service provided by the Company has been approved or endorsed by Goldman or any of its affiliates without the prior written consent of Goldman.

5.10 Stockholders Agreement. Notwithstanding the terms of the Stockholders Agreement, the Company agrees not to exercise its right of first refusal (and Goldman shall not have to comply with Article III of the Stockholders Agreement) with respect to the Shares to the extent that Goldman Transfers (as defined in the Stockholders Agreement) the Shares to (a) any of its Affiliates (as defined in the Stockholders Agreement) and (b) from and after the third anniversary hereof, any existing shareholders of the Company. For avoidance of doubt, if the

Company does not exercise its option to purchase the Shares for any proposed Transfer by Goldman pursuant to which Article III of the Stockholders Agreement applies, such Transfer will be deemed a permissible Transfer under Section 2.3 thereof.

6.2 This Agreement shall be deemed to have been made and delivered in New York City and shall be governed as to validity, interpretation, construction, effect and in all other respects by the internal laws of the State of New York. Each of Goldman and the Company (1) agree that any legal suit, action or proceeding arising out of or relating to this Agreement, shall be instituted exclusively in New York State Supreme Court, County of New York, or in the United States District Court for the Southern District of New York, unless such court shall have refused such jurisdiction, (2) waives any objection which Goldman or the Company may have now or hereafter to the venue of any such suit, action or proceeding, and (3) irrevocably consents to the jurisdiction of the New York State Supreme Court, County of New York, and the United States District Court for the Southern District of New York in any such suit, action or

proceeding. Each of Goldman and the Company further agrees to accept and acknowledge service of any and all process which may be served in any such suit, action or proceeding in the New York State Supreme Court, County of New York, or in the United States District Court for the Southern District of New York and agrees that service of process upon Goldman or the Company, as the case may be, mailed by certified mail to Xxxxxxx’x address or the Company’s address, as the case may be, set forth in Section 6.1 above shall be deemed in every respect effective service of process upon Goldman or the Company, as the case may be, in any such suit, action or proceeding.

6.3 Each party hereto agrees to use its reasonable best efforts to take any action which may be necessary or appropriate or reasonably requested by the other party hereto in order to effectuate or implement the provisions of this Agreement.

6.4 Except as provided in Section 5.2, this Agreement is not assignable without the consent of the other parties hereto. In the event of an assignment, the rights and obligations of the parties under this Agreement shall bind and inure to the benefit of the parties and their respective successors and assigns.

6.5 Each of the parties hereto hereby agrees that representations and warranties made by or on behalf of it in this Agreement or in any document or instrument delivered pursuant hereto shall survive the Closing Date and continue in effect until the second anniversary of the Closing Date (expect to the extent written notice of claim with respect thereto has been delivered prior to the second anniversary of the closing date, in which case, such representations and warranties shall survive until the final resolution of such claim). The covenants and agreements contained in this Agreement or in any document or instrument delivered pursuant hereto shall survive the Closing Date and shall continue in effect in accordance with their respective terms. Subject to the terms of this Section 6.5, each party shall indemnify, defend and hold harmless the other, its affiliates, and each of their respective officers, directors, partners (and the partners of such partners), managing directors, employees, agents, advisors, consultants, and representatives, and the successors and assigns of any of the foregoing (including any transferee of Shares to the extent they are affiliates of Goldman) from and against all losses, liabilities, costs or expenses (including reasonable attorney’s fees and expenses) (collectively, “Losses”) incurred or suffered by any of the foregoing (whether incurred or suffered directly or indirectly through ownership of the Shares or otherwise) arising out of, relating to, or resulting from (i) the breach of any representation or warranty made by it in this Agreement or (ii) the breach of, or the failure to perform, any covenant or agreement of it made in this Agreement. Neither party shall have any obligation to indemnify the other party for any Losses pursuant to clause (i) until the aggregate of all Losses suffered by the party seeking indemnification equals or exceeds $120,000, and then the obligation of the indemnifying party shall be only the extent of such excess. The aggregate amount that either party shall have to pay in respect of its indemnification obligations pursuant to clause (i) shall not exceed $12,000,000. Except in the event of fraud, the sole and exclusive remedy for any breach or failure to be true and correct, or alleged breach or failure to be true and correct, of any representation or warranty in this Agreement, shall be indemnification in accordance with this Section 6.5.

6.6 This Agreement may be executed in separate counterparts, all of which shall constitute one agreement.
