3

(b) On the date Aveon Holdings Partnership Units are surrendered for exchange, all rights of the exchanging Aveon Holdings Limited Partner as holder of such Aveon Holdings Partnership Units shall cease, and such exchanging Aveon Holdings Limited Partner or its designee shall be treated for all purposes as having become the Record Holder (as defined in the Issuer Partnership Agreement) of such Common Units and shall be admitted as a Limited Partner (as defined in the Issuer Partnership Agreement) of the Issuer in accordance and upon compliance with Section 10.2 of the Issuer Partnership Agreement.

(c) For the avoidance of doubt, any exchange of Aveon Holdings Partnership Units shall be subject to the provisions of the Aveon Holdings Partnership Agreements, including without limitation the provisions of Sections 8.1 and 8.3.

Section 2.2 Exchange Procedures. (a) An Aveon Holdings Limited Partner may exercise the right to exchange Aveon Holdings Partnership Units set forth in Section 2.1(a) above by providing a written notice of exchange at least thirty (30) days prior to the applicable Quarterly Exchange Date, or within such shorter period of time as may be agreed by the parties hereto, to each of the Aveon Holdings General Partners substantially in the form of Exhibit A hereto, duly executed by such holder or such holder’s duly authorized attorney in respect of the Aveon Holdings Partnership Units to be exchanged, delivered during normal business hours at the principal executive offices of the Aveon Holdings General Partners.

(c) The Aveon Holdings Partnerships may adopt reasonable procedures for the implementation of the exchange provisions set forth in this Article II, including, without limitation, procedures for the giving of notice of an election for exchange.

Section 2.3 Blackout Periods and Ownership Restrictions. Notwithstanding anything to the contrary, an Aveon Holdings Limited Partner shall not be entitled to exchange Aveon Holdings Partnership Units, and the Issuer and the Aveon Holdings Partnerships shall have the right to refuse to honor any request for exchange of Aveon Holdings Partnership Units, at any time or during any period (i) if the Issuer or the Aveon Holdings Partnerships shall determine, based on the advice of counsel (which may be inside counsel), that there may be material non-public information relating to the Issuer and/or one or more of the Aveon Holdings Partnerships that may affect the trading price per Common Unit at such time or during such period, (ii) if such exchange would be prohibited under applicable law or regulation, (iii) to the extent such Aveon Holdings Limited Partner would be prohibited from holding Common Units under the Issuer Partnership Agreement or (iv) to the extent such exchange would not be permitted under the policies and procedures established by the general partners of the Aveon Holdings Partnerships.

Except as may be required in the immediately preceding sentence, no adjustments in respect of distributions shall be made upon the exchange of any Aveon Holdings Partnership Unit.

Section 2.5 Common Units to be Issued. The Issuer covenants that if any Common Units require registration with or approval of any governmental authority under any U.S. federal or state law before such Common Units may be issued upon exchange pursuant to this Article II, the Issuer shall use commercially reasonable efforts to cause such Common Units to be duly registered or approved, as the case may be. The Issuer shall use commercially reasonable efforts to list the Common Units required to be delivered upon exchange prior to such delivery upon each national securities exchange or inter-dealer quotation system upon which the outstanding Common Units may be listed or traded at the time of such delivery.

Section 3.5 Severability. If any term or other provision of this Agreement is held to be invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions is not affected in any manner materially adverse to any party. Upon a determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 3.7 Waiver. No failure by any party to insist upon the strict performance of any covenant, duty, agreement or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof shall constitute waiver of any such breach of any other covenant, duty, agreement or condition.

Section 3.8 Submission to Jurisdiction; Waiver of Jury Trial.

(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 in accordance with the then-existing Rules of Arbitration of the International Chamber of 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.

7

Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings.

(b) Notwithstanding the provisions of paragraph (a), the Aveon Holdings Partnerships may cause any Aveon Holdings Partnership to bring, on behalf of the Issuer or such Aveon Holdings Partnership or on behalf of one or more Aveon Holdings Limited 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 Aveon Holdings Limited Partner (i) expressly consents to the application of paragraph (c) of this Section 3.8 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 Aveon Holdings Partnerships as such Aveon Holdings Limited Partner’s agents for service of process in connection with any such action or proceeding and agrees that service of process upon such agent, who shall promptly advise such Aveon Holdings Limited Partner of any such service of process, shall be deemed in every respect effective service of process upon the Aveon Holdings Limited Partner in any such action or proceeding.

(c) (i) Each Aveon Holdings Limited 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 this Section 3.8, or any judicial proceeding ancillary to an arbitration or contemplated arbitration arising out of or relating to or concerning this agreement.

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 3.8, 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 3.8. In that case, this Section 3.8 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 3.8 shall be construed to omit such invalid or unenforceable provision.

Copies of executed counterparts transmitted by telecopy or other electronic transmission service shall be considered original executed counterparts for purposes of this Section 3.9.

Section 3.10 Fulfillment of Partnership Obligations.
