Notwithstanding the foregoing and anything to the contrary contained in this Consent or in the Transaction Documents (as defined in the Merger Agreement), if any “lock-ups” applicable to GSC Secondary Interest Fund, LLC, any CEH Holder, any other holder of CEH Units (as defined in the Merger Agreement), any holder of equity interests in Holdco Sub or any holder of Equity Securities issued pursuant to a GSCAC Equity Raise shall be amended or waived to reduce the term of the lock-up period to a date that is earlier than 180 days after the Closing Date, then the lock-up period applicable to the Note Holders and Option Holders (or their respective Designees pursuant to Section 7(j) below) pursuant to this Section 4(e) shall be similarly reduced or waived, as the case may be. For the avoidance of doubt, none of Xxxxxx Xxxxxxx & Co. Incorporated, its Designees pursuant to

Section 7(j) below or its Permitted Transferees shall be bound by the provisions of this Section 4(e).

(f) Regulatory Filings. Each Note Holder and Option Holder (other than Xxxxxx Xxxxxxx & Co. Incorporated) agrees (i) to prepare and file, as soon as is practical following the execution of this Consent, all filings under the Xxxx-Xxxxx-Xxxxxx Antitrust Improvements Act of 1976 as amended (the “HSR Act”) applicable to it in connection with the transactions contemplated by this Consent or any other Transaction Document (as defined in the Merger Agreement) to which such Person is a party and (ii) reasonably to cooperate in the preparation and filing, as soon as practical following the execution of this Consent, of all filings by CEH (or any of its Subsidiaries) and/or GSCAC under the FPA applicable to such Note Holder or Option Holder, as the case may be, in connection with the transactions contemplated by this Consent or any other Transaction Document (as defined in the Merger Agreement) to which such Note Holder or Option Holder, as the case may be, is a party. No TCW/MS Party or any of their respective Affiliates will be required to (x) enter into any settlement, undertaking, consent decree, stipulation or agreement with any Governmental Authority in connection with the transactions contemplated by this Consent or any Transaction Document (as defined in the Merger Agreement) to which such TCW/MS Party is a party or (y) divest or hold separate any business or assets in connection with the consummation of the transactions contemplated by this Consent or any Transaction Document (as defined in the Merger Agreement) to which such TCW/MS Party is a party. Each Party agrees to cooperate, and to furnish non-confidential information in such Party’s possession that is necessary, in connection with the preparation of filings or submissions by any other Party or any Subsidiary of CEH under any federal, state or local Laws in connection with the transactions contemplated by this Consent or any Transaction Document (as defined in the Merger Agreement).

(g) Confidentiality. From the date hereof through the Closing, but subject to Section 7(k)(ii), each TCW/MS Party agrees not to disclose or permit the disclosure of any confidential, non-public or proprietary information relating to the assets or the business of the GSCAC Parties and/or CEH and its Subsidiaries provided to it pursuant to or in connection with this Consent (collectively, “Confidential Information”); provided that such disclosure may be made (i) to any Person who is an Affiliate or a Representative (as defined below) of such TCW/MS Party, to any Representative of the GSCAC Parties or the CEH Parties, or to any rating agency or valuation firm engaged by such TCW/MS Party, in each case, solely for their use and on a need-to-know basis; provided, further, that such Persons are notified of such TCW/MS Party’s confidentiality obligations hereunder, (ii) to a proposed transferee of the Existing Notes and the Cash Settled Options, provided that such proposed transferee enters into a confidentiality agreement containing comparable terms and conditions as set forth in this Section 4(g) prior to disclosure of such Confidential Information, (iii) pursuant to a subpoena, order or regulation issued by a court, arbitrator or governmental body, agency or official (a “Requesting Authority”) or pursuant to a formal request issued under the rules and regulations of, or applicable to, a Requesting Authority, or as required to obtain an approval from a Governmental Authority, provided that, to the extent permitted by applicable Law, the disclosing TCW/MS Party formally requests confidential treatment of the Confidential Information pursuant to the rules and regulations applicable to the Requesting Authority or Governmental Authority to which Confidential Information is being provided if and to the extent confidential treatment is available pursuant to such rules and regulations, (iv) to representatives of any bank regulatory authority in

connection with their examination of the records of the TCW/MS Party or any Affiliate thereof, (v) to any lender providing financing to such TCW/MS Party or any Affiliate thereof, provided that such lender enters into a confidentiality agreement containing comparable terms and conditions as set forth in this Section 4(g) prior to disclosure of such Confidential Information, or (vi) to the extent already public through no fault of such TCW/MS Party under this Consent. For purposes of this Consent, “Representative” shall mean, as to any Person, holders of individual accounts managed by such Person and such Person’s officers, directors, employees, managers, members, partners, shareholders, owners, beneficiaries, counsel, accountants, advisors, trustees, consultants and agents.

(h) Public Disclosure. From the date hereof through the Closing, but subject to Section 4(g) and Section 7(k)(ii), each TCW/MS Party agrees that no public release or announcement concerning this Consent, the transactions contemplated by this Consent or any Transaction Document (as defined in the Merger Agreement) shall be issued by such TCW/MS Party without the prior consent of GSCAC and CEH, unless such TCW/MS Party determines that it is required by any Laws or by the rules and regulations of, or pursuant to any agreement with, a stock exchange or trading system. If any TCW/MS Party determines that it is required by any Laws or by the rules and regulations of, or pursuant to any agreement with, a stock exchange or trading system, to make this Consent and the terms of the transactions contemplated by this Consent or any other Transaction Documents public or otherwise issue a press release or make public disclosure with respect thereto, it shall, to the extent permitted by Law, at a reasonable time before making any public disclosure, consult with the GSCAC and CEH regarding such disclosure and give GSCAC and CEH reasonable time to comment on such release or announcement in advance of such issuance.

(i) Accounts. CEH covenants and agrees to, and to cause its Subsidiaries to, operate their respective bank accounts (including, without limitation, the Designated Accounts) and to make all deposits of cash and cash equivalents thereinto and all payments therefrom, in each case, in accordance with the provisions of the Project Financing Documents, the Trust Indenture, the Existing Note Purchase Agreement and the Existing Holdco Credit Agreement and in the ordinary course of business consistent with past practice.

Section 5. Preemptive Rights.

(a) Subject to Section 5(f) below, prior to the issuance by GSCAC of any Applicable Securities (as defined below), which issuance would result in an adjustment in the number of Warrant Shares issuable upon the exercise of the Initial GSCAC Warrants pursuant to Section 11(d) or Section 11(e) of the Initial Warrant Agreement, GSCAC shall give each TCW/MS Party notice (an “Issuance Notice”) of any such proposed issuance at least 20 Business Days prior to the proposed issuance date. The Issuance Notice shall specify the price at which such Applicable Securities are to be issued and the other material terms of the issuance. Each TCW/MS Party shall be entitled to purchase up to such TCW/MS Party’s Pro Rata Share of the Applicable Securities proposed to be issued, at the price and on the terms specified in the Issuance Notice. “Applicable Securities” means shares of Class A common stock, par value $0.001 per share, of GSCAC now or hereafter authorized or any other class of stock of GSCAC, however designated, that has the right (subject to any prior rights of any class or series of preferred stock) to participate in any distribution of the assets or earnings of GSCAC without limit as to per share

amount. “Pro Rata Share” means, for any TCW/MS Party, the fraction that results from dividing (i) the number of shares of GSCAC Class A Common Stock and GSCAC Class B Common Stock owned by such TCW/MS Party (immediately before giving effect to such issuance) by (ii) the total number of shares of GSCAC Class A Common Stock and GSCAC Class B Common Stock then outstanding (immediately before giving effect to such issuance).

(b) Each TCW/MS Party who desires to purchase any or all of its Pro Rata Share of the Applicable Securities specified in the Issuance Notice must deliver notice to GSCAC (each an “Exercise Notice”) of its election to purchase such Applicable Securities within 10 Business Days after its receipt of the Issuance Notice. The Exercise Notice must specify the number (or amount) of Applicable Securities to be purchased by such TCW/MS Party and shall constitute exercise by such TCW/MS Party of its rights under this Section 5 and a binding agreement of such TCW/MS Party to purchase, at the price and on the terms specified in the Issuance Notice, the number of shares (or amount) of Applicable Securities specified in the Exercise Notice. If, at the termination of such 10-Business-Day period, any TCW/MS Party shall not have delivered an Exercise Notice to GSCAC, such TCW/MS Party shall be deemed to have waived all of its rights under this Section 5 with respect to the purchase of such Applicable Securities.

(c) GSCAC shall have a period of 90 days after the date of the Issuance Notice to consummate the proposed issuance of any or all of such Applicable Securities that the TCW/MS Parties have not elected to purchase at the price and upon terms that are not materially less favorable to GSCAC than those specified in the Issuance Notice, provided that, if such issuance is subject to regulatory approval, such 90-day period shall be extended until the expiration of five Business Days after all such approvals have been received, but in no event later than 180 days from the date of the Issuance Notice. If GSCAC proposes to issue any such Applicable Securities after such 90-day (or 180-day) period, it shall again comply with the procedures set forth in this Section 5.

(d) The closing of the purchase and sale of Applicable Securities to the TCW/MS Parties that have delivered Exercise Notices to GSCAC shall take place at substantially the same time as the issuance to other Persons. At such closing, GSCAC shall issue to each such TCW/MS Party the Applicable Securities to be purchased by such TCW/MS Party, registered in the name of such TCW/MS Party, against payment by such TCW/MS Party of the purchase price for such Applicable Securities in accordance with the terms and conditions as specified in the Issuance Notice.

(e) For the avoidance of doubt, all references to “TCW/MS Party” in this Section 5 shall be to each such TCW/MS Party, together with its Permitted Transferees and its Designee pursuant to Section 7(j) below.

(f) The provisions of this Section 5 become effective after the Closing and shall terminate on June 25, 2011.

Section 6. Waiver of Claims Against Trust Account.

(a) Each TCW/MS Party understands that GSCAC is a recently organized “blank check company” formed for the purpose of acquiring one or more businesses or assets (an

“Initial Business Combination”). Each of the TCW/MS Parties further acknowledges that GSCAC’s sole assets consist of the cash proceeds of the recent initial public offering (the “IPO”) and private placement of its securities, and that substantially all of those proceeds have been deposited in a trust account with a third party (the “Trust Account”) for the benefit of GSCAC, its public stockholders (as defined in the agreement governing the Trust Account) and the underwriters of its IPO. The monies in the Trust Account may be disbursed only (1) to GSCAC in limited amounts from time to time (and in no event more than $2,400,000 in total) in order to permit GSCAC to pay its operating expenses; (2) if GSCAC completes an Initial Business Combination, to certain dissenting public stockholders, to the underwriters in the amount of underwriting discounts and commissions they earned in the IPO but whose payment they have deferred, and then to GSCAC; and (3) if GSCAC fails to complete an Initial Business Combination within the allotted time period and liquidates subject to the terms of the agreement governing the Trust Account, to GSCAC in limited amounts to permit GSCAC to pay the costs and expenses of its liquidation and dissolution and then to GSCAC’s public stockholders.

(b) Each of the TCW/MS Parties hereby waives any right, title, interest or claim of any kind (each, a “Claim”) that it has or may have in the future in or to any monies in the Trust Account and not to seek recourse against the Trust Account or any funds distributed therefrom (except amounts released to GSCAC as described in clause (1) of the preceding paragraph or amounts distributed to GSCAC (excluding amounts described in clause (2) of the preceding paragraph) at or after the consummation of its Initial Business Combination) as a result of, or arising out of, any Claims against GSCAC in connection with this Consent or any related transactions.

(b) Amendment. No provision, term or condition of this Consent may be amended except by a writing signed by each Party hereto.

(c) Governing Law. This Consent shall be governed by and construed in accordance with the laws of the State of New York (including Section 5-1401 of the General Obligations Law of the State of New York) without giving effect to any conflict or choice of law provision that would result in the imposition of another state’s law.

(d) Submission to Jurisdiction. Any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Consent or the transactions contemplated hereby may be brought in any State or Federal court of competent jurisdiction in the State, County and City of New York. Each of the Parties hereby irrevocably consents to the nonexclusive jurisdiction and venue of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. Each Party agrees that service of process on such Party made by registered or certified mail, return receipt requested, postage prepaid as provided in Section 7(a) shall be effective service of process on such Party. Notwithstanding the foregoing, each Party agrees that each other Party retains the right to serve process in any other manner permitted by law or to bring proceedings against it in the courts of any other jurisdiction.

(e) WAIVER OF JURY TRIAL. WITH RESPECT TO ANY LEGAL ACTION OR PROCEEDING RELATING TO, ARISING OUT OF OR BASED UPON THIS CONSENT OR THE TRANSACTIONS CONTEMPLATED, EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY. THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS CONSENT. In the event of litigation, this Consent may be filed as a written consent to a trial by the court. The scope of this waiver is intended to be all-

encompassing of any and all disputes that may be filed in any court and that relate to the subject matter of this transaction, including contract claims, tort claims, breach of duty claims and all other common law and statutory claims. Each Party hereby warrant and represent that each has reviewed this waiver with its legal counsel, and that each knowingly and voluntarily waives its jury trial rights following consultation with legal counsel.

(f) Fees and Expenses. Each of the CEH Parties acknowledges and agrees that, upon the earlier to occur of the Closing and the termination of this Consent (but subject to the proviso below), all costs, fees and expenses incurred by Agent, Note Holders, Option Holders and their counsel arising under, relating to or in connection with this Consent, the Existing Note Purchase Agreement, the Cash Settled Options, the other Transaction Documents, the New TCW/MS Financing Documents, the Merger, the Transaction Documents (as defined in the Merger Agreement) and the transactions contemplated hereby and thereby, including, without limitation, all regulatory filing fees, shall be for the account of CEH and shall be paid by CEH to Agent, Note Holders and/or Option Holders, as applicable; provided, however, that CEH shall promptly (and in any event within five Business Days following demand therefor) reimburse the applicable TCW/MS Party for any and all costs in respect of regulatory filing fees.

(g) Counterparts. This Consent may be executed in counterparts, each of which when so executed and delivered shall be deemed an original, and when taken together shall constitute but one and the same instrument.

(h) Effect on Transaction Documents.

(i) Except as specifically modified by this Consent, the Existing Note Purchase Agreement and the other Transaction Documents shall remain in full force and effect.

(ii) This Consent shall be deemed an Additional Transaction Document (as defined in the Existing Note Purchase Agreement); provided, however, that no breach of this Consent (other than the failure at Closing to deliver the Payoff Consideration to the TCW/MS Parties in accordance with the provisions of this Consent) in and of itself shall constitute a breach or default under the Existing Note Purchase Agreement or any other Transaction Document.

(i) Entire Agreement. This Consent, the Transaction Documents and the Transaction Documents (as defined in the Merger Agreement) constitute the entire agreement among the Parties concerning the subject matter hereof.

(j) Successors and Assigns. The provisions of this Consent shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns; provided that (i) except as permitted by, and in accordance with, Section 1(a)(i) or Section 1(l), no Party may assign, delegate or otherwise transfer any of its rights or obligations under this Consent without the consent of each other Party and (ii) each TCW/MS Party shall be permitted to designate a Designee to receive any Payoff Consideration to which such TCW/MS Party is entitled hereunder but such TCW/MS Party must deliver written notice of such designation to CEH and GSCAC not later than 30 days after the date hereof and the Designee must provide to

CEH and GSCAC a written agreement to be bound by the provisions of this Consent to the extent applicable, which agreement shall include representations by such Designee with respect to the matters set forth in Section 2(e). For purposes of this Consent, “Designee” shall mean, with respect to any Note Holder or Option Holder, any Person (1) that is administrated or managed by such Note Holder or Option Holder, as the case may be, (2) that is an Affiliate of such Note Holder or Option Holder, as the case may be, (3) that is an entity or an Affiliate of an entity that administers or manages such Note Holder or an Option Holder, as the case may be, or (4) that is a shareholder, partner, member, account holder or trust beneficiary of such Note Holder or Option Holder, as the case may be.

(k) Survival of Representations, Warranties and Agreements.

(i) It is expressly agreed by the Parties that the representations, warranties, pre-Closing covenants and pre-Closing agreements set forth in this Consent shall terminate and be of no further force or effect upon the Closing; provided that the representations and warranties set forth in each of Section 2(a) (other than Section 2(a)(iv)), Section 2(b)(i), Section 2(b)(ii), Section 2(b)(iii), Section 2(b)(vi), Section 2(c), Section 2(d) and Section 2(e) shall survive the Closing. This Section 7(k) shall not limit in any way the survival and enforceability of any covenant or agreement of the Parties hereto which by its terms contemplates performance on or after the Closing, which shall survive the Closing.

(ii) Notwithstanding anything to contrary contained in this Consent, the agreements of the Parties contained in Section 4(g), Section 4(h) and this Section 7 (other than Section 7(m)) shall survive the termination of this Consent.

(l) Exculpation; Limitation on Liability.

(i) If the Merger Agreement or this Consent is terminated in accordance with its terms, no CEH Party or GSCAC Party shall have any liability to the TCW/MS Parties for any breach of any representation, warranty, covenant or agreement contained in the Merger Agreement and incorporated herein by reference.

(ii) None of Agent, any Note Holder, any Option Holder or any of their respective Affiliates shall have any liability for any breach by any party to the Merger Agreement of any representation, warranty, covenant or agreement contained in the Merger Agreement.

(iii) No Party nor any of its Affiliates shall have any liability for any breach of any representation, warranty, covenant or agreement contained in this Consent (or incorporated herein by reference) and made or to be performed prior to the Closing, except each Party shall be liable to the other Parties for all Losses (as defined in the Merger Agreement) incurred or suffered by the other Parties as a result of (i) the willful and knowing failure of such Party (or any of its Affiliates) to perform any covenant required by this Consent to be performed or complied with by such Party at or before the Closing or (ii) any willful and knowing breach by such Party (or any of its Affiliates) of

any representation or warranty of such Party contained in this Consent (or incorporated herein by reference).

(iv) No Affiliate of any Party, nor any of their respective partners, beneficiaries, trustees, investment managers or advisers, or any investor or participant in the partners of any Party, nor any of their respective officers, directors, employees, partners, members, shareholders, owners, counsel, accountants, financial advisers or consultants shall have any liability to any Party or any other Person as a result of the breach of any representation, warranty, covenant, agreement or obligation of such Party in this Consent or any instrument or document delivered pursuant to this Consent, the Merger Agreement or any other Transaction Document (as defined in the Merger Agreement).

(v) No Note Holder or Option Holder shall have any liability for (i) the breach by any other Note Holder or Option Holder of any representation, warranty, covenant or agreement of such other Note Holder or Option Holder contained in this Consent or (ii) the failure of any other Note Holder or Option Holder to execute the TCW/MS Closing Acknowledgment.

(vi) Without limiting the foregoing or the generality of the provisions of the Existing Note Purchase Agreement, Agent shall be entitled to rely on certifications from any Party in making any determination in respect of any matter under this Consent and shall have no liability for relying on any such certifications. Each Party acknowledges and agrees that (1) if Agent shall have requested instructions from the Note Holders and Option Holders, Agent shall be entitled to refrain from taking any action hereunder unless Agent shall have received instructions from the Note Holders and Option Holders, (2) no Party or its Affiliates shall have any right of action against Agent as a result of Agent acting or refraining from acting hereunder in accordance with the instructions of the Note Holders and Option Holders, (3) Agent shall be fully justified in failing or refusing to take any action hereunder if such action would, in the opinion of Agent, be contrary to law or the terms of this Consent and (4) Agent shall have no obligation to deliver the TCW/MS Closing Acknowledgment unless Agent shall have been instructed to deliver the TCW/MS Closing Acknowledgment by each Note Holder and each Option Holder. Each Party further acknowledges and agrees that neither Agent nor any of its Affiliates nor any of their respective officers, directors, employees, agents or representatives shall be liable for any action taken or omitted to be taken by it under this Consent or in connection herewith, except for damages determined by a final order of a court of competent jurisdiction to have been caused by Agent’s or their own willful misconduct or fraud.

(vii) Notwithstanding anything in this Consent to the contrary, no Party nor any of its Affiliates shall be liable for special, punitive, exemplary, incidental, consequential or indirect damages, or lost profits, whether based on contract, tort, strict liability, other law or otherwise and whether or not arising from any other Party’s or such Party’s Affiliates’ sole, joint or concurrent negligence, strict liability or other fault.

(m) Specific Performance. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Consent were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Consent and to enforce specifically the terms and provisions hereof in any court of the United States or any State having jurisdiction.

IN WITNESS WHEREOF, this Consent, Exchange and Preemptive Rights Agreement has been duly executed and delivered by the duly authorized officer of each Party as of the date first above written.

Xxxxxxx, Xxxxx X. Xxxxxx, GSC Acquisition Company, GSCAC Holdings I LLC, GSCAC Holdings II LLC, GSCAC Merger Sub LLC, TCW Asset Management Company in its capacity as administrative agent for the Note Holders (as defined in that certain Note Purchase Agreement dated as of August 16, 2005 among CEH/La Paloma Holding Company, LLC, TCW Asset Management Company in its capacity as administrative agent for the Note Holders (as defined therein), and each Person identified as a Note Purchaser on the signature pages thereto, as amended by that certain Consent, Waiver and Amendment No. 1 to Note Purchase Agreement, dated as of November 30, 2007, and as may be further amended, supplemented, restated or otherwise modified) and each Note Holder and each Option Holder identified on the signature pages thereto, including [_______________] (the “Fund”).

This letter will confirm the agreement between the Company1, [Parent]2 and the Fund to provide the Fund with the contractual rights set forth below during the period of time that the Fund is a holder of [shares of GSCAC Class A Common Stock / GSCAC Class B Common Stock/ Holdco Class B Common Units / Holdco Class C Common Units / Holdco Class D Common Units / TCW/MS Contingent Warrants], or any other equity securities of the Company [or Parent] resulting from the reclassification, conversion, exchange or exercise of any of the foregoing (the “Fund Equity Securities”).

1. With respect to financial statements and other information, upon and to the extent so requested by the Fund, the Company shall deliver to the Fund:

(a) as soon as available, but in any event within 45 days after the end of each of the first three quarterly periods of each Fiscal Year of the Company, the unaudited consolidated balance sheet of the Company and its consolidated Subsidiaries as at the end of such quarter

(c) to the extent the Company is required by law or pursuant to the terms of any outstanding indebtedness of the Company to prepare such reports, any annual reports, quarterly reports and other periodic reports pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 actually prepared by the Company as soon as available.

2. (a) With respect to inspection and access, the Company and its Subsidiaries shall provide to the Fund, true and correct copies of all documents, reports, financial data and other information as the Fund may reasonably request. Additionally, the Company shall permit any authorized representatives designated by the Fund to visit and inspect any of the properties of the Company and its Subsidiaries or any of its Subsidiaries, including its and their books of account, and to discuss its and their affairs, finances and accounts with its and their officers, all at such times as the Fund may reasonably request; provided, however, that the Company and its Subsidiaries reserve the right to withhold any information if access to such information could reasonably be expected to adversely affect the attorney-client privilege between the Company and its Subsidiaries and their respective counsel.

(b) The Fund agrees not to disclose or permit the disclosure of any confidential, non-public or proprietary information relating to the assets or the business of the Company and its Subsidiaries provided to it and marked “Confidential” by the Company or any of its Subsidiaries pursuant to or in connection with this letter agreement that is designated by the provider thereof as confidential (collectively, “Confidential Information”); provided that such disclosure may be made (i) to any Person who is an Affiliate or a Representative (as defined below) of such Fund, to any Representative of the Company and its Subsidiaries, or to any rating agency or valuation firm engaged by the Fund, in each case, solely for their use and on a need-to-know basis;

provided, further, that such Persons are notified of the Fund’s confidentiality obligations hereunder, (ii) to a proposed transferee of the Fund Equity Securities, provided that such proposed transferee enters into a confidentiality agreement containing comparable terms and conditions as set forth in this paragraph 2 prior to disclosure of such Confidential Information, (iii) pursuant to a subpoena, order or regulation issued by a court, arbitrator or governmental body, agency or official (a “Requesting Authority”) or pursuant to a formal request issued under the rules and regulations of, or applicable to, a Requesting Authority, or as required to obtain an approval from a Governmental Authority, provided that, to the extent permitted by applicable Law, the Fund formally requests confidential treatment of the Confidential Information pursuant to the rules and regulations applicable to the Requesting Authority or Governmental Authority to which Confidential Information is being provided if and to the extent confidential treatment is available pursuant to such rules and regulations, (iv) to representatives of any bank regulatory authority in connection with their examination of the records of the Fund or any Affiliate thereof, (v) to any lender providing financing to the Fund or any Affiliate thereof, provided that such lender enters into a confidentiality agreement containing comparable terms and conditions as set forth in this paragraph 2 prior to disclosure of such Confidential Information, or (vi) to the extent already public through no fault of the Fund under this letter agreement.

3. The Fund shall have the right to consult with and advise the management of the Company and its Subsidiaries, upon reasonable notice at reasonable times from time to time, on all matters relating to the operation of the Company and its Subsidiaries.

4. In connection with the foregoing contractual rights, the Company will take such action as is necessary in order to cause any Subsidiary of the Company to comply with the obligations of this letter.

[Upon the exchange or conversion of any Holdco Class B Common Units and GSCAC Class B Common Stock held by the Fund for shares of GSCAC Class A Common Stock pursuant to the Exchange Rights or otherwise in accordance with the terms of the Holdco Sub LLC Agreement, all references to the Company in paragraphs 1 through 4 above shall also be deemed to be references to Parent.]

The rights granted to the Fund by the Company [or Parent, as the case may be,] in this letter agreement are intended to satisfy the requirement of management rights for purposes of qualifying the Fund’s investments in the Company as “venture capital investments” for purposes of the Department of Labor “plan assets” regulation, 29 C.F.R. § 2510.3-101. In the event the aforementioned rights are not satisfactory for such purpose, the Company[, Parent] and the Fund shall reasonably cooperate in good faith to agree upon mutually satisfactory management rights that satisfy such regulations. Furthermore, the rights granted to the Fund by the Company [or Parent, as the case may be,] in this letter agreement are not in substitution for, and shall not be deemed to be in limitation of, any rights otherwise available to the Fund as a holder of any securities of the Company [or Parent, as the case may be]. In addition, the Company [or Parent, as the case may be,] shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company [or Parent, as the case may be,] to expressly assume and agree to perform this agreement in the same manner and to the same extent that the Company [or Parent, as the case may be,] would have been required to perform if no such succession had taken place.

In the event the Fund transfers, sells, assigns or otherwise disposes of all or substantially all of the Fund Equity Securities to a person or group of persons acting together (the “Transferee”), the Company [and Parent] hereby agree[s] to enter into a substantially similar letter agreement with such Transferee.

The agreements of the Fund set forth in paragraph 2(b) above shall survive the termination of this letter agreement.

No provision of this letter agreement may be modified or waived or discharged unless agreed to in writing by the Fund, the Company [and Parent]. No waiver by the Fund at any time of any breach by the Company [or Parent] of, or compliance with, any condition or provision of this letter agreement to be performed by the Company [or Parent] shall be deemed a waiver of any similar or dissimilar provision or condition at the same or at any prior or subsequent time.

This letter agreement and the rights and the obligations of the parties hereto shall be governed by, and construed, enforced and interpreted in accordance with, the internal laws of the State of New York (including Section 5-1401 of the General Obligations Law of the State of New York) without regard to conflict of laws principles, and may be executed in counterparts, This letter agreement may be executed by one or more of the parties hereto on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

IN WITNESS WHEREOF, the parties have executed this VCOC Management Rights Letter as of the date first appearing above.
