Each Limited Partner represents and warrants that such Limited Partner understands that the Interests have not been registered under the Securities Act of 1933 and therefore such Interests may not be resold without registration under the Securities Act of 1933 or exemption from such registration, and that accordingly such Limited Partner must bear the economic risk of an investment in the Partnership for an indefinite period of time.

Each Limited Partner represents that to the full satisfaction of the Limited Partner, the Limited Partner has been furnished any materials that such Limited Partner has requested relating to the Partnership, any investment and the offering of Interests and has been afforded the opportunity to ask questions of representatives of the Partnership concerning the terms and conditions of the offering of Interests and any matters pertaining to each investment and to obtain any other additional information relating thereto. Each Limited Partner represents that the Limited Partner has consulted to the extent deemed appropriate by the Limited Partner with the Limited Partner’s own advisers as to the financial, tax, legal and related matters concerning an investment in Interests and on that basis believes that an investment in the Interests is suitable and appropriate for the Limited Partner.

(b) To the extent the Partnership receives distributions from any Issuer which are intended to allow holders of securities of the Issuer to pay tax liabilities associated with income allocable to such holders of securities (a “Tax Distribution”), the Partnership shall make a corresponding Tax Distribution to each Partner pro rata based on such Partner’s share of allocable taxable income.

12. Allocations of Profits and Losses.

(a) Profits and losses of the Partnership for each fiscal year to be allocated to the Capital Accounts of the Partners shall be calculated and determined by the General Partner in respect of the Partners’ Interests with respect to a particular Investment separately from the calculation and determination of any such allocation to be made in respect of the Partners’ Interests with respect to any other Investment.

(b) Notwithstanding any other provision of this Agreement, (i) “partner nonrecourse deductions” (as defined in Treasury Regulations Section 1.704-2(i)), if any, of the Partnership shall be allocated for each fiscal year to the Partner that bears the economic risk of loss within the meaning of Treasury Regulations Section 1.704-2(i), and (ii) “nonrecourse deductions” (as defined in Treasury Regulations Section 1.704-2(b)) and “excess nonrecourse liabilities” (as defined in Treasury Regulations Section 1.752-3(a)), if any, shall be allocated to and among the Partners in accordance with their relative Profit Sharing Percentages.

(c) This Agreement shall be deemed to include “qualified income offset,” “minimum gain chargeback” and “partner nonrecourse debt minimum gain chargeback” provisions within the meaning of Treasury Regulations under Section 704(b) of the Internal Revenue Code of 1986, as amended (the “Code”).

(d) Any allocations required to be made pursuant to Sections 12(b) or (c) (the “Regulatory Allocations”) (other than allocations, the effect of which are likely to be offset in the future by other special allocations) shall be taken into account, to the extent permitted by the Treasury Regulations, in computing subsequent allocations of income, gain, loss or deduction pursuant to Section 12 so that the net amount of any items so allocated and all other items allocated to each Partner shall, to the extent possible, be equal to the amount that would have been allocated to each Partner pursuant to Section 12 had such Regulatory Allocations not occurred.

8

(e) Tax Allocations. All items of income, gain, loss, deduction and credit of the Partnership shall be allocated among the Partners for federal, state and local income tax purposes consistent with the manner that the corresponding constituent items shall be allocated among the Partners pursuant to this section, except as may otherwise be provided herein or by the Code.

In respect of an income tax audit of any tax return of the Partnership, the filing of any amended return or claim for refund in connection with any item of income, gain, loss, deduction or credit reflected on any tax return of the Partnership, or any administrative or judicial proceedings arising out of or in connection with any such audit, amended return, claim for refund or denial of such claim, (A) the Tax Matters Partner (as defined below) shall be authorized to act for, and his decision shall be final and binding upon, the Partnership and all Partners except to the extent a Partner shall properly elect to be excluded from such proceeding pursuant to the Code, (B) all expenses incurred by the Tax Matters Partner in connection therewith (including, without limitation, attorneys’, accountants’ and other experts’ fees and disbursements) shall be expenses of the Partnership and (C) no Partner shall have the right to (1) participate in the audit of any Partnership tax return, (2) file any amended return or claim for refund in connection with any item of income, gain, loss, deduction or credit reflected on any tax return of the Partnership (unless he provides prior notice of such action to the Partnership as provided above), (3) participate in any administrative or judicial proceedings conducted by the Partnership or the Tax Matters Partner arising out of or in connection with any such audit, amended return, claim for refund or denial of such claim, or (4) appeal, challenge or otherwise protest any adverse findings in any such audit conducted by the Partnership or the Tax Matters Partner or with respect to any such amended return or claim for refund filed by the Partnership or the Tax Matters Partner or in any such administrative or judicial proceedings conducted by the Partnership or the Tax Matters Partner. The Partnership and each Partner hereby designate any Partner selected by the General Partner as the “tax matters partner” for purposes of Section 6231(a)(7) of the Code (the “Tax Matters Partner”). To the fullest extent permitted by applicable law, each Partner agrees to indemnify and hold harmless the Partnership and all other Partners from and against any and all liabilities, obligations, damages, deficiencies and expenses resulting from any breach or violation by such Partner of the provisions of this Section 19 and from all actions, suits, proceedings, demands, assessments, judgments, costs and expenses, including reasonable attorneys’ fees and disbursements, incident to any such breach or violation. The Partners intend for the Partnership to be treated as a partnership for U.S. federal income tax purposes, and no election to the contrary shall be made.

(b) To the extent the Partnership reasonably believes that it is required by law to withhold or to make tax payments on behalf of or with respect to any Partner or the Partnership is subjected to tax itself by reason of the status of any Partner (“Tax Advances”), the Partnership may withhold such amounts and make such tax payments as so required, shall promptly pay the Tax Advances so withheld to the applicable taxing authority and shall promptly deliver to such Partner a certified copy of an original official receipt received by the Partnership, or other reasonable evidence, showing such payment. All Tax Advances made on behalf of a Partner (other than Tax Advances in respect of amounts previously withheld from distributions to such Partner) shall be repaid by reducing the amount of the current or next succeeding distribution or distributions which would otherwise have been made to such Partner or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation otherwise payable to such Partner. For all purposes of this Agreement such Partner shall be treated as having received the amount of the distribution that is equal to the Tax Advance. If the Partnership shall distribute an amount to a Partner and subsequently determine that it was

13

required to, but did not, withhold taxes on such amount, the applicable Partner shall promptly, after notification by the Partnership, reimburse the Partnership for such withholding tax (but not for any associated penalties, interests or additions to tax). The Partnership shall promptly pay the applicable tax authority the amount required to be withheld and shall furnish the applicable Partner with a copy of an official receipt for such withholding.

(c) To the fullest extent permitted by law, each Partner hereby agrees to indemnify and hold harmless the Partnership and the other Partners from and against any liability (including, without limitation, any liability for taxes, penalties, additions to tax or interest) with respect to income attributable to or distributions or other payments to such Partner.

20. Ownership and Use of Names. The Partnership acknowledges that Blackstone TM L.L.C. (“TM”), a Delaware limited liability company with a principal place of business at 345 Park Avenue, New York, New York 10154, (or its successors or assigns) is the sole and exclusive owner of the mark and name BLACKSTONE and that the ownership of, and the right to use, sell or otherwise dispose of, the firm name or any abbreviation or modification thereof which consists of or includes BLACKSTONE, shall belong exclusively to TM, which company (or its predecessors, successors or assigns) has licensed the Partnership to use BLACKSTONE in its name. The Partnership acknowledges that TM owns the service mark BLACKSTONE for various services and that the Partnership is using the BLACKSTONE mark and name on a non-exclusive, non-sublicensable and non-assignable basis in connection with its business and authorized activities with the permission of TM. All services rendered by the Partnership under the BLACKSTONE mark and name will be rendered in a manner and with quality levels that are consistent with the high reputation heretofore developed for the BLACKSTONE mark by TM and its affiliates and licensees. The Partnership understands that TM may terminate its right to use BLACKSTONE at any time in TM’s sole discretion by giving the Partnership written notice of termination. Promptly following any such termination, the Partnership will take all steps necessary to change its company name to one which does not include BLACKSTONE or any confusingly similar term and cease all use of BLACKSTONE or any term confusingly similar thereto as a service mark or otherwise.

21. Exculpation and Indemnification.

(a) Notwithstanding any other provision of this Agreement, whether express or implied, to the fullest extent permitted by law, no Partner nor any of such Partner’s representatives, agents or advisors nor any partner, member, officer, employee, representative, agent or advisor of the Partnership or any of its affiliates (individually, a “Covered Person” and collectively, the “Covered Persons”) shall be liable to the Partnership or any other Partner for any act or omission (in relation to the Partnership, this Agreement, any related document or any transaction or investment contemplated hereby or thereby) taken or omitted by a Covered Person (other than any act or omission constituting Cause (as defined above, and as applied to any Covered Person mutatis mutandis)), unless there is a final and non-appealable judicial determination and/or determination of an arbitrator that such Covered Person did not act in good faith and in what such Covered Person reasonably believed to be in, or not opposed to, the best interests of the Partnership and within the authority granted to such Covered Person by this Agreement, and, with respect to any criminal act or proceeding, had reasonable cause to believe

14

that such Covered Person’s conduct was unlawful. Each Covered Person shall be entitled to rely in good faith on the advice of legal counsel to the Partnership, accountants and other experts or professional advisors, and no action taken by any Covered Person in reliance on such advice shall in any event subject such person to any liability to any Partner or the Partnership. To the extent that, at law or in equity, a Partner has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to another Partner, to the fullest extent permitted by law, such Partner acting under this Agreement shall not be liable to the Partnership or to any such other Partner for its good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they expand or restrict the duties and liabilities of a Partner otherwise existing at law or in equity, are agreed by the Partner, to the fullest extent permitted by law, to modify to that extent such other duties and liabilities of such Partner.

(b) (i) To the fullest extent permitted by law, the Partnership shall indemnify and hold harmless (but only to the extent of the Partnership’s assets (including, without limitation, the remaining commitments of the Partner to make capital contributions to the Partnership) each Covered Person from and against any and all claims, damages, losses, costs, expenses and liabilities (including, without limitation, amounts paid in satisfaction of judgments, in compromises and settlements, as fines and penalties and legal or other costs and reasonable expenses of investigating or defending against any claim or alleged claim), joint and several, of any nature whatsoever, known or unknown, liquidated or unliquidated (collectively, “Losses”), arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, in which the Covered Person may be involved, or threatened to be involved, as a party or otherwise, by reason of such Covered Person’s management of the affairs of the Partnership or which relate to or arise out of or in connection with the Partnership, its property, its business or affairs (other than claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, arising out of any act or omission of such Covered Person constituting “Cause” (as defined above)); provided, that a Covered Person shall not be entitled to indemnification under this Section with respect to any claim, issue or matter if there is a final and non-appealable judicial determination and/or determination of an arbitrator that such Covered Person did not act in good faith and in what such Covered Person reasonably believed to be in, or not opposed to, the best interest of the Partnership and within the authority granted to such Covered Person by this Agreement, and, with respect to any criminal act or proceeding, had reasonable cause to believe that such Covered Person’s conduct was unlawful; provided further, that if such Covered Person is a Partner or a withdrawn Partner, such Covered Person shall bear its share of such Losses in accordance with such Covered Person’s Profit Sharing Percentage in the Partnership as of the time of the actions or omissions that gave rise to such Losses. To the fullest extent permitted by law, expenses (including legal fees) incurred by a Covered Person (including, without limitation, a Partner) in defending any claim, demand, action, suit or proceeding may, with the approval of a majority-in-interest of the Partners, from time to time, be advanced by the Partnership prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Partnership of a written undertaking by or on behalf of the Covered Person to repay such amount to the extent that it shall be subsequently determined that the Covered Person is not entitled to be indemnified as authorized in this Section, and the Partnership and its affiliates shall have a continuing right of offset against such Covered Person’s interests/investments in the Partnership and such affiliates and shall have the right to withhold amounts otherwise distributable to such Covered Person to satisfy such repayment obligation. If

15

a Partner institutes litigation against a Covered Person which gives rise to an indemnity obligation hereunder, such Partner shall be responsible, up to the amount of such Partner’s interests and remaining capital contribution commitment, for such Partner’s pro rata share of the Partnership’s expenses related to such indemnity obligation, as determined by a majority-in-interest of the Partners. The Partnership may purchase insurance, to the extent available at reasonable cost, to cover losses, claims, damages or liabilities covered by the foregoing indemnification provisions. Partners shall not be personally obligated with respect to indemnification pursuant to this Section 22.

(ii) (A) Notwithstanding anything to the contrary herein, for greater certainty, it is understood and/or agreed that the Partnership’s obligations hereunder are not intended to render the Partnership as a primary indemnitor for purposes of the indemnification, advancement of expenses and related provisions under applicable law governing a particular Portfolio Entity (as defined below) through which an investment is directly or indirectly held. It is further understood and/or agreed that a Covered Person shall first seek to be so indemnified and have such expenses advanced in the following order of priority: first out of proceeds available in respect of applicable insurance policies maintained by any Issuer or any other entity in which the Partnership may invest, directly or indirectly (each, a “Portfolio Entity”), and second by the applicable Portfolio Entity through which such investment is directly or indirectly held (only to the extent the foregoing sources are exhausted).

(B) The Partnership’s obligation, if any, to indemnify or advance expenses to any Covered Person shall be reduced by any amount that such Covered Person may collect as indemnification or advancement from the applicable Portfolio Entity (including by virtue of any applicable insurance policies maintained thereby), and to the extent the Partnership (or any affiliate thereof) pays or causes to be paid any amounts that should have been paid by the applicable Portfolio Entity (including by virtue of any applicable insurance policies maintained thereby), it is agreed among the Partners that the Partnership shall have a subrogation claim against such Portfolio Entity in respect of such advancement or payments. The General Partner and the Partnership shall be specifically empowered to structure any such advancement or payment as a loan or other arrangement (except for a loan to an executive officer of The Blackstone Group L.P. or any of its affiliates, which shall not be permitted) as the General Partner may determine necessary or advisable to give effect to or otherwise implement the foregoing.

22. Confidentiality. By executing this Agreement, each Partner expressly agrees, at all times during the term of the Partnership and thereafter and whether or not at the time a Partner of the Partnership, to maintain the confidentiality of, and not to disclose to any person other than the Partnership, another Partner or a person designated by the Partnership, any information relating to the business, financial structure, financial position or financial results, clients or affairs of the Partnership that shall not be generally known to the public or the securities industry, except as otherwise required by law or by any regulatory or self-regulatory organization having jurisdiction; provided, that any corporate Partner may disclose any such information it is required by law, rule, regulation or custom to disclose. Notwithstanding anything in this Agreement to the contrary, to comply with Treasury Regulation Section 1.6011-4(b)(3)(i), each Partner (and any employee, representative or other agent of such Partner) may

16

disclose to any and all persons, without limitation of any kind, the U.S. federal income tax treatment and tax structure of the Partnership, it being understood and agreed, for this purpose, (1) the name of, or any other identifying information regarding (a) the Partners or any existing or future investor (or any affiliate thereof) in any of the Partners, or (b) any investment or transaction entered into by the Partners; (2) any performance information relating to any of the Partners or their investments; and (3) any performance or other information relating to previous funds or investments sponsored by any of the Partners, does not constitute such tax treatment or tax structure information.

23. Power of Attorney. To the extent permitted by applicable law, each Limited Partner hereby irrevocably makes, constitutes and appoints the General Partner as its true and lawful agent and attorney in fact, with full power of substitution and full power and authority in its name, place and stead, to make, execute, sign, acknowledge, swear to, record and file (i) this Agreement and any amendment to this Agreement which has been adopted as herein provided; (ii) the original certificate of exempted limited partnership of the Partnership and all amendments thereto required or permitted by law and the provisions of this Agreement; (iii) all certificates and other instruments deemed advisable by the General Partner to carry out the provisions of this Agreement and applicable law or to permit the Partnership to become or to continue as an exempted limited partnership or partnership wherein the Limited Partners have limited liability in each jurisdiction where the Partnership may be doing business; (iv) all instruments that the General Partner or the Liquidator deems appropriate to reflect a change or modification of this Agreement or the Partnership in accordance with this Agreement, including, without limitation, the admission of additional Limited Partners or substituted Limited Partners pursuant to the provisions of this Agreement; (v) all conveyances and other instruments or papers deemed advisable by the General Partner or a liquidator of the Partnership to effect the dissolution and termination of the Partnership; (vi) all fictitious or assumed name certificates required (in light of the Partnership’s activities) to be filed on behalf of the Partnership; (vii) all agreements and instruments necessary or advisable to consummate any Investment; (viii) any agreement pursuant to the ELP Law to continue the business of the Partnership and to appoint a successor General Partner upon the withdrawal of the sole remaining General Partner; and (ix) all other instruments or papers which may be required or permitted by law to be filed on behalf of the Partnership which are not legally binding on the Limited Partners in their individual capacity and are necessary to carry out the provisions of this Agreement, and to take all action necessary to continue the business of the Partnership and to appoint a successor General Partner upon the Withdrawal of the sole remaining General Partner pursuant to the ELP Law. This power of attorney is intended to secure an interest in property, and, in addition, the obligations of each relevant Limited Partner under this Agreement.

24. Jurisdiction.

(a) Any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) shall be finally settled by arbitration conducted by a single arbitrator in New York, New York U.S.A. in accordance with the then-existing Rules of Arbitration of the International Chamber of

17

Commerce. If the parties to the dispute fail to agree on the selection of an arbitrator within thirty (30) days of the receipt of the request for arbitration, the International Chamber of Commerce shall make the appointment. The arbitrator shall be a lawyer and shall conduct the proceedings in the English language. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings.

(b) Notwithstanding the provisions of paragraph (a), the General Partner may bring, or may cause the Partnership to bring, on behalf of the General Partner or the Partnership or on behalf of one or more Partners, an action or special proceeding in any court of competent jurisdiction for the purpose of compelling a party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration hereunder, and/or enforcing an arbitration award and, for the purposes of this paragraph (b), each Partner (i) expressly consents to the application of paragraph (c) of this Section 25 to any such action or proceeding, (ii) agrees that proof shall not be required that monetary damages for breach of the provisions of this Agreement would be difficult to calculate and that remedies at law would be inadequate, and (iii) irrevocably appoints the General Partner as such Partner’s agent for service of process in connection with any such action or proceeding and agrees that service of process upon any such agent, who shall promptly advise such Partner of any such service of process, shall be deemed in every respect effective service of process upon the Partner in any such action or proceeding.

(c) (i) EACH PARTNER HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF COURTS LOCATED IN NEW YORK, NEW YORK FOR THE PURPOSE OF ANY JUDICIAL PROCEEDING BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF PARAGRAPH (b) OF THIS SECTION 25, OR ANY JUDICIAL PROCEEDING ANCILLARY TO AN ARBITRATION OR CONTEMPLATED ARBITRATION ARISING OUT OF OR RELATING TO OR CONCERNING THIS AGREEMENT. Such ancillary judicial proceedings include any suit, action or proceeding to compel arbitration, to obtain temporary or preliminary judicial relief in aid of arbitration, or to confirm an arbitration award. The parties acknowledge that the forum(s) designated by this paragraph (c) have a reasonable relation to this Agreement, and to the parties’ relationship with one another.

(ii) The parties hereby waive, to the fullest extent permitted by applicable law, any objection which they now or hereafter may have to personal jurisdiction or to the laying of venue of any such ancillary suit, action or proceeding brought in any court referred to in paragraph (c)(i) of this Section 25 and such parties agree not to plead or claim the same.

(d) Notwithstanding any provision of this Agreement to the contrary, this Section 25 shall be construed to the maximum extent possible to comply with the laws of the State of Delaware, USA, including the Delaware Uniform Arbitration Act (10 Del. C. § 5701 et seq.) (the “Delaware Arbitration Act”). If, nevertheless, it shall be determined by a court of competent jurisdiction that any provision or wording of this Section 25, including any rules of the International Chamber of Commerce, shall be invalid or unenforceable under the Delaware Arbitration Act, or other applicable law, such invalidity shall not invalidate all of this Section 25. In that case, this Section 25 shall be construed so as to limit any term or provision so as to make it valid or enforceable within the requirements of the Delaware Arbitration Act or other applicable law, and, in the event such term or provision cannot be so limited, this Section 25 shall be construed to omit such invalid or unenforceable provision.

25. Counterparts. This Agreement may be executed in several counterparts, all of which will together constitute a single agreement among the parties.
