(b) The sale, disposition or termination of all of the property then owned by the Partnership. (c) The occurrence of an event of withdrawal from the Partnership by the General Partner as provided for in the Partnership. (d) The consent in writing of the General Partner and all of the Limited Partners. (e) The occurrence of any event which, under the Act, causes the dissolution of a limited partnership. Section 8.2. Liquidation and Termination. Upon dissolution of the Partnership, the General Partner or, if the withdrawal of the General Partner caused the dissolution of the Partnership, a person selected by all of the Limited Partners, shall act as liquidator or shall appoint one or more liquidators who shall have full authority to wind up the affairs of the Partnership and make final distribution as provided herein. The liquidator shall continue to operate the Partnership properties with all of the power and authority of the General Partner. The steps to be accomplished by the liquidator are as follows: (a) As promptly as possible after dissolution and again after final liquidation, the liquidator, if requested by any Partner, shall cause a proper accounting to be made by the Partnership's independent accountants of the Partnership's assets, liabilities and operations through -13- 17 the last day of the month in which the dissolution occurs or the final liquidation is completed, as appropriate. (b) The liquidator shall pay all of the debts and liabilities of the Partnership (including all expenses incurred in liquidation) or otherwise make adequate provision therefor (including without limitation the establishment of a cash escrow fund for contingent liabilities in such amount and for such term as the liquidator may reasonably determine). After making payment or provision for all debts and liabilities of the Partnership, the Partners' Capital Accounts shall then be adjusted by (i) assuming the sale of all remaining assets of the Partnership for cash at their respective fair market values (as determined by an appraiser selected by the liquidator) as of the date of termination of the Partnership and (ii) debiting or crediting each Partner's Capital Account with its respective share of the hypothetical gains or losses resulting from such assumed sales in the same manner as each such Capital Account would be debited or credited for gains or losses on actual sales of such assets. The liquidator shall then by payment of cash or property (valued as of the date of termination of the Partnership at its fair market value by the appraiser selected in the manner provided above) distribute to the Partners such amounts as are required to pay the positive balances of their respective Capital Accounts. Such a distribution shall be in cash or in kind as determined by the liquidator. Any distribution to the Partners in liquidation of the Partnership shall be made by the latter of either the end of the taxable year in which the liquidation occurs or on a date which is not more than ninety (90) days after the date of such liquidation. For purposes of the preceding sentence, the term "liquidation" shall have the same meaning as set forth in Treasury Regulation Section 1.704-1(b)(2)(ii) as in effect at such time. Each Partner shall have the right to designate another person to receive any property which otherwise would be distributed in kind to that Partner pursuant to this Section 8.2. (c) Except as expressly provided herein, the liquidator shall comply with any applicable requirements of the Act and all other applicable laws pertaining to the winding up of the affairs of the Partnership and the final distribution of its assets. (d) Notwithstanding any provision in this Agreement to the contrary, no Partner shall be obligated to restore a deficit balance in its Capital Account at any time. The distribution of cash and/or property to the Partners in accordance with the provisions of this Section 8.2 shall constitute a complete return to the Partners of their Capital Contributions and a complete distribution to the Partners of their interest in the Partnership and all Partnership property. Section 8.3. Reconstitution. Notwithstanding the foregoing or any other provision of this Agreement, upon the occurrence of an event of dissolution described in Section 8.1, the Partners may unanimously consent to the reconstitution of the Partnership, and the business of the Partnership shall be continued without being wound up as provided for in the Act. -14- 18 ARTICLE IX Assignments of Interests Section 9.1. Assignment by Partners. (a) No Partner's interest in the Partnership shall be assigned, mortgaged, pledged, subjected to a security interest or otherwise encumbered, in whole or in part, without the prior written consent of all of the other Partners, and any attempt by a Partner to assign its interest without such consent shall be void ab initio. (b) Unless an assignee becomes a substituted Partner in accordance with the provisions set forth below, such assignee shall not be entitled to any of the rights granted to a Partner hereunder, other than the right to receive allocations of income, gain, loss, deduction, credit and similar items and distributions to which the assignor would otherwise be entitled, to the extent such items are assigned. (c) An assignee of the interest of a Partner, or any portion thereof, shall become a substituted Partner entitled to all of the rights of a Partner if, and only if (i) the assignor gives the assignee such right, (ii) the Partners consent to such substitution, the granting or denying of which shall be in each Partner's sole discretion, and (iii) the assignee executes and delivers such instruments, in form and substance satisfactory to the General Partner, as the General Partner may deem necessary or desirable to effect such substitution and to confirm the agreement of the assignee to be bound by all of the terms and provisions of this Agreement. Upon the satisfaction of such requirements, the General Partner shall concurrently (or as of such later date as shall be provided for in any applicable written instruments furnished to the General Partner) admit any such assignee as a substituted Partner of the Partnership and reflect such admission and the date thereof in the records of the Partnership. (d) The Partnership and the General Partner shall be entitled to treat the record owner of any Partnership interest as the absolute owner thereof in all respects and shall incur no liability for distributions of cash or other property made in good faith to such owner until such time as a written assignment of such interest that complies with the terms of this Agreement has been received by the General Partner. -15- 19 ARTICLE X Miscellaneous Section 10.1. Notices. All notices, elections, demands or other communications required or permitted to be made or given pursuant to this Agreement shall be in writing and shall be considered as properly given or made if given by (a) personal delivery, (b) prepaid telegram, telex or facsimile (provided that such telegram, telex or facsimile is confirmed by expedited delivery service), or (c) expedited delivery service with proof of delivery, addressed to the respective addressee(s) specified in Section 1.5.

Every provision in this Agreement is intended to be severable. If any term or provision hereof is illegal or invalid for any reason whatsoever, such illegality or invalidity shall not affect the validity of the remainder of this Agreement. Section 10.6. No Waiver. The failure of any Partner to insist upon strict performance of a covenant hereunder or of any obligation hereunder, irrespective of the length of time for which such failure continues, shall not be a waiver of such Partner's right to demand strict compliance in the future. No consent or waiver, express or implied, to or of any breach or default in the performance of any obligation hereunder shall constitute a consent or waiver to or of any other breach or default in the performance of the same or any other obligation hereunder. Section 10.7. Applicable Law. This Agreement and the rights and obligations of the parties hereunder shall be governed by and interpreted, construed and enforced in accordance with the laws of the State of Delaware. Section 10.8. Meetings of the Partners.

Such meetings may be held by conference telephone and shall be held at such times and places, as often and in such manner as shall be determined by the General Partner.

Section 10.9. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns; provided, however, that no Partner may sell, assign, transfer or otherwise dispose of all or any part of its rights or interest in the Partnership or under this Agreement except in accordance with Article IX. Section 10.10. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be an original and all of which shall constitute but one and the same document. -17- 21 IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the day and year first above written.
