The General Partner may take any action on behalf of the Company without the vote or approval of any Limited Partner, including an action to create under the provisions of this Agreement a class or group of partnership interests that was not previously outstanding.

(b) The General Partner may, from time to time, delegate to one or more Persons such authority and duties as the General Partner may deem advisable. In addition, the General Partner may assign titles (including, without limitation, chairman, chief executive officer, president, vice president, secretary, assistant secretary, treasurer and assistant treasurer) to any such Persons and delegate to such other individuals certain authority and duties. Any number of titles may be held by the same individual. Any delegation pursuant to this Section 4.2(b) may be revoked at any time by the General Partner.

4.3 Limited Partner Rights; Meetings.

(a) No Limited Partner shall have any right, power or duty, including, without limitation, the right to approve or vote on any matter, except as expressly required by the Partnership Act or other applicable law or as expressly provided hereunder.

(c) Meetings of the Partners may be held at such place or places as shall be determined from time to time by resolution of the General Partner. At all meetings of the Company, business shall be transacted in such order as shall from time to time be determined by

resolution of the General Partner. Regular meetings of the Company shall be held at such times and places as may be designated from time to time by resolution of the General Partner, in its sole discretion. Notice of such meetings shall not be required. Special meetings of the Company may be called by the General Partner, and notice of such meeting need not state the purpose or purposes of, nor the business to be transacted at, such meeting, except as may otherwise be required by law.

(d) Each Limited Partner shall have the right to receive upon request from the Company a copy of the Certificate and of this Agreement, as amended from time to time, and such other information regarding the Company as is required by the Partnership Act, subject to reasonable conditions and standards established by the General Partner, which may include, without limitation, restrictions on the use of confidential information.

4.4 Action by Written Consent or Telephone Conference. Any action permitted or required by the Partnership Act, the Certificate or this Agreement to be taken at a meeting of the Company may be taken without a meeting if a consent in writing, setting forth the action to be taken, is signed by the General Partner. Such consent shall have the same force and effect as a unanimous vote at a meeting and may be stated as such in any document or instrument filed with the Secretary of State of Delaware, and the execution of such consent shall constitute attendance or presence in person at a meeting of the Partners. Subject to the requirements of the Partnership Act, the Certificate or this Agreement for notice of meetings, unless otherwise restricted by the Certificate, the Partners may participate in and hold a meeting by means of a telephone conference or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation in such meeting shall constitute attendance and presence in person at such meeting.

The General Partner may assign titles to particular officers. Unless the General Partner otherwise decides, if the title is one commonly used for officers of a corporation, the assignment of such title shall constitute the delegation to such officer of the authority and duties that are normally associated with that office of a corporation.

Such resignation shall be made in writing and shall take effect at the time specified therein, or if no time be specified, at the time of its receipt by the General Partner. Any officer may be removed as such, either with or without cause, by the General Partner. Designation of an officer shall not of itself create contract rights. Any vacancy occurring in any office of the Company may be filled by the General Partner.

5.1 Exculpation, Notwithstanding any other provisions of this Agreement, whether express or implied, or any obligation or duty at law or in equity, none of the Partners or any other officers, directors, stockholders, partners, employees, affiliates, representatives, or agents of any of the Partners, nor any officer, employee, representative or agent of the Company (individually, a “Covered Person” and collectively, the “Covered Persons”) shall be liable to the Company or any other person bound by this Agreement for any act or omission (in relation to the Company, its property or the conduct of its business or affairs, this Agreement, any related document or any transaction or investment contemplated hereby or thereby) taken or omitted by a Covered Person in the reasonable belief that such act or omission is in or is not contrary to the best interests of the Company and is within the scope of authority granted to such Covered Person by the Agreement, provided such act or omission does not constitute fraud, willful misconduct, bad faith, or gross negligence.

5.2 Indemnification. To the fullest extent permitted by law, the Company shall indemnify and hold harmless each Covered Person from and against any and all losses, claims, demands, liabilities, expenses, judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative (“Claims”), in which the Covered Person may be involved, or threatened to be involved, as a party or otherwise, by reason of its management of the affairs of the Company or which relates to or arises out of the Company or its property, business or affairs. A Covered Person shall not be entitled to indemnification under this Section 5.2 with respect to (i) any Claim with respect to which such Covered Person has engaged in fraud, willful misconduct, bad faith or gross negligence or (ii) any Claim initiated by such Covered Person unless such Claim (or part thereof) (A) was brought to enforce such Covered Person’s rights to indemnification hereunder or (B) was authorized or consented to by the General Partner. Expenses incurred by a Covered Person in defending any Claim shall be paid by the Company in advance of the final disposition of such Claim upon receipt by the Company of an undertaking by or on behalf of such Covered Person to repay such amount if it shall be ultimately determined that such Covered Person is not entitled to be indemnified by the Company as authorized by this Section 5.2.

5.3 Amendments. Any repeal or modification of this Article V by the Partners shall not adversely affect any rights of such Covered Person pursuant to this Article V, including the right to indemnification and to the advancement of expenses of a Covered Person existing at the

ARTICLE VI

TAXES AND BOOKS

6.1 Tax Returns. The General Partner shall cause to be prepared and filed all necessary federal and state income tax returns for the Company, including making any elections the General Partner may deem appropriate and in the best interests of the Company.

6.2 Books. The Company shall keep books and records of accounts and shall keep minutes of the proceedings of its Partners. The calendar year shall be the accounting year of the Company.

6.3 Tax Matters Partner. The Company and each Partner hereby designate the General Partner as the “tax matters partner” for purposes of Section 6231(a)(7) of the Code (the “Tax Matters Partner”); provided that, if the designation of the General Partner as the Tax Matters Partner is deemed invalid for any reason, then the Partners agree to designate a substitute Tax Matters Partner from among the Partners and the Tax Matters Partner so designated shall automatically and irrevocably appoint the General Partner to act as its agent in carrying out all rights and duties of the Tax Matters Partner. In respect of an income tax audit of any tax return of the Company, 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 Company, 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, (i) the Tax Matters Partner shall be authorized to act for, and its decision shall be final and binding upon, the Company and all Partners except to the extent a Partner shall properly elect to be excluded from such proceeding pursuant to the Code, (ii) all expenses incurred by the Tax Matters Partner in connection therewith (including, without limitation, reasonable attorneys’, accountants’ and other experts’ fees and disbursements) shall be expenses of, and payable by, the Company, (iii) no Limited Partner shall have the right to (A) participate in the audit of any tax return of the Company, (B) file any amended return or claim for refund in connection with any item of income, gain, loss, deduction or credit (other than items which are not partnership items within the meaning of Section 6231(a)(4) of the Code or which cease to be partnership items under Section 6231(b) of the Code) reflected on any tax return of the Company, (C) participate in any administrative or judicial proceedings conducted by the Company 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 (D) appeal, challenge or otherwise protest any adverse findings in any such audit conducted by the Company or the Tax Matters Partner or with respect to any such amended return or claim for refund filed by the Company or the Tax Matters Partner or in any such administrative or judicial proceedings conducted by the Partnership or the Tax Matters Partner, and (iv) the Tax Matters Partner shall keep the Limited Partners reasonably apprised of the status of any such proceeding. Notwithstanding the previous sentence, if a petition for a readjustment to any partnership item included in a final partnership administrative adjustment is filed with a United States District Court or the United States Court of Claims and the United States Internal Revenue Service has elected to assess income tax against a Partner with respect to that final partnership

administrative adjustments (rather than suspending assessments until the District Court or Court of Claims proceedings become final), such Partner shall be permitted to file a claim for refund within such period of time to avoid application of any statute of limitation provisions which would otherwise prevent the Partner from having any claim based on the final outcome of that review.

ARTICLE VII

TRANSFERS

7.1 Assignment by Partners. Any Partner may freely sell, assign or transfer all or any part of such Partner’s Units or other interests in the Company, and the creation of any pledge, security interest, mortgage, encumbrance or other restriction on the Partnership Units is expressly permitted.

7.2 Substituted Partner.

(a) An assignee of any Units or other interests in the Company of a Partner, or any portion thereof, shall become a substituted Partner entitled to all the rights of a Partner if and only if the assignor gives the assignee such right.

(b) Upon the admission of a substituted Partner, Schedule A attached hereto shall be amended to reflect the name, address and Units and other interests in the Company of such substituted Partner and to eliminate the name and address of and other information relating to the assigning Partner with regard to the assigned Units and other interests in the Company.

(b) Any Person who acquires in any manner whatsoever any Units or other interest in the Company, irrespective of whether such Person has accepted and adopted in writing the terms and provisions of this Agreement, shall be deemed by the acceptance of the benefits of the acquisition thereof to have agreed to be subject to and bound by all the terms and conditions of this Agreement that any predecessor in such Units or other interest in the Company of such Person was subject to or by which such predecessor was bound.

7.4 Effect of Incapacity. Except as otherwise provided herein, the Incapacity of a Partner shall not dissolve or terminate the Company. In the event of such Incapacity, the executor, administrator, guardian, trustee or other personal representative of the Incapacitated Partner shall be deemed to be the assignee of such Partner’s Units or other interests in the Company and may, subject to Section 7.1, become a substituted Partner upon the terms and conditions set forth in Section 7.3.

DISSOLUTION, LIQUIDATION AND TERMINATION

8.1 Dissolution. The Company shall dissolve, and its affairs shall be wound up, at such time as (a) all of the Partners of the Company approve in writing, (b) an event of withdrawal of the General Partner has occurred under the Partnership Act, (c) there are no Limited Partners of the Company unless the business of the Company is continued in accordance with the Partnership Act, or (d) an entry of a decree of judicial dissolution has occurred under §17-802 of the Partnership Act; provided, however, the Company shall not be dissolved or required to be wound up upon an event of withdrawal of a general partner described in Section 8.1(b) if (i) at the time of such event of withdrawal, there is at least one (1) other general partner of the Company who carries on the business of the Company (any remaining general partner being hereby authorized to carry on the business of the Company), or (ii) within ninety (90) days after the occurrence of such event of withdrawal, all remaining Partners agree in writing to continue the business of the Company and to the appointment, effective as of the date of the event of withdrawal, of one (1) or more additional general partners of the Company.

The costs of winding up shall be borne as an expense of the Company. The steps to be accomplished by the liquidating trustee are as follows:

(a) first, the liquidating trustee shall satisfy all of the Company’s debts and liabilities to creditors other than Partners (whether by payment or the making of reasonable provision for payment thereof);

(b) second, the liquidating trustee shall satisfy all of the Company’s debts and liabilities to Partners (whether by payment or the making of reasonable provision for payment thereof); and

GENERAL PROVISIONS

9.1 Notices. Except as expressly set forth to the contrary in this Agreement, all notices, requests, or consents provided for or permitted to be given under this Agreement must be in writing and must be given either by depositing that writing in the United States mail, addressed to the recipient, postage paid, and registered or certified with return receipt requested or by delivering that writing to the recipient in person, by courier, or by facsimile transmission; and a notice, request, or consent given under this Agreement is effective on receipt by the Person to receive it. All notices, requests, and consents to be sent to a Partner must be sent to or made at the address given for that Partner on Schedule A, or such other address as that Partner may specify by notice to the other Partners. Whenever any notice is required to be given by law, the Certificate or this Agreement, a written waiver thereof, signed by the Person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice.

9.2 Entire Agreement. This Agreement constitutes the entire agreement of the Partners and their affiliates relating to the Company and supersedes all prior contracts or agreements among the Partners with respect to the Company, whether oral or written.

9.3 Effect of Waiver or Consent. A waiver or consent, express or implied, to or of any breach or default by any Person in the performance by that Person of its obligations with respect to the Company is not a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person with respect to the Company. Failure on the part of a Person to complain of any act of any Person or to declare any Person in default with respect to the Company, irrespective of how long that failure continues, does not constitute a waiver by that Person of its rights with respect to that default until the applicable statute-of-limitations period has run.

TO THE LAW OF ANOTHER JURISDICTION. In the event of a direct conflict between the provisions of this Agreement and any provision of the Certificate or any mandatory provision of the Partnership Act, the applicable provision of the Certificate or the Partnership Act shall control. If any provision of this Agreement or the application thereof to any Person or circumstance is held invalid or unenforceable to any extent, the remainder of this Agreement and the application of that provision to other Persons or circumstances is not affected thereby and that provision shall be enforced to the greatest extent permitted by law.

9.7 Counterparts. This Agreement may be executed in multiple counterparts with the same effect as if all signing parties had signed the same document. All counterparts shall be construed together and constitute the same instrument.

9.8 No Third Party Beneficiaries. No person or entity which is not a party hereto shall have any rights or obligations pursuant to this Agreement.
