(a)                                 net profits shall be allocated, (i) first, to the Partners, until the cumulative net profit allocated pursuant to this Clause (a)(i) for the current fiscal period and all prior periods equals the cumulative net loss allocated pursuant to Clauses (b)(n) and (b)(iii) hereof for all prior periods, such net profit to be allocated under this Clause (a)(i) in the reverse order net loss was allocated under said Clauses and which allocations have not previously been eliminated under this Clause (a)(i), and, (ii) thereafter, the balance of net profit, if any, shall be allocated to the Partners in accordance with their respective Profit Ratios; and

3

(b)                                 net loss shall be allocated, (i) first, to the Partners, until the cumulative net loss allocated pursuant to this Clause (b)(i) for the current fiscal period and all prior periods equals the cumulative net profit allocated pursuant to Clause (a)(ii) hereof for all prior periods, allocated among the Partners in the proportion that such cumulative net profit was allocated thereunder, and, (ii) next, to the Partners in accordance with their respective Loss Ratios, provided, no allocation shall be made to a Partner with an Adjusted Capital Account equal to or less than zero (“Adjusted Capital Account Deficit”); and (iii) thereafter, to the Partners without an Adjusted Capital Account Deficit, pro rata among such Partners in accordance with such Partners’ relative Loss Ratios; provided, however, all allocations under this Clause (b)(iii) to be made, at all times, subject to the proviso contained in Clause (b)(ii).

The following special allocations shall be made prior to application of the foregoing provision: (i) deductions arising from taxes and other items incurred by the Partnership which items are attributable to certain Partners (rather than the Partnership or the Partners generally), shall, in the reasonable discretion of the General Partner, be specially allocated to such Partners and (ii) deductions relating to charitable contributions shall be specially allocated to the General Partner.

11.2                        Special Allocations.

Notwithstanding any provisions of Section 11.1 hereof, the following special allocations of Partnership loss, deductions, Section 705(a)(2)(B) expenditures, gain and income shall be made in the following order (and in all instances in accordance with Regulation Section 1.704-2(j)):

(a)                                 Minimum Gain Chargeback (Nonrecourse Liabilities). Except as otherwise provided in Regulation Section 1.704-2(c), if there is a net decrease in Partnership Minimum Gain for any fiscal year, each Partner shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to that Partner’s share of the net decrease in Partnership Minimum Gain. The items to be so allocated shall be determined in accordance with Regulation Section 1.704-2(f). This Section 11.2(a) is intended to comply with the minimum gain chargeback requirement in said section of the regulations and shall be interpreted consistently therewith. Allocations pursuant to this paragraph shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant hereto.

(b)                                 Minimum Gain Attributable to Partner Nonrecourse Debt. Except as otherwise provided in Regulation Section 1.704-2(i)(4), if there is a net decrease in Minimum Gain Attributable to Partner Nonrecourse Debt during any fiscal year, each Partner shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to that Partner’s share of the net decrease in the Minimum Gain Attributable to Partner Nonrecourse Debt. The items to be so allocated shall be determined in accordance with Regulation Section 1.704-2(i)(4) and (j)(2). This Section 11.2(b) is intended to comply with the minimum gain chargeback requirement with respect to Partner

Nonrecourse Debt contained in said section of the Regulations and shall be interpreted consistently therewith. Allocations pursuant to this paragraph shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant hereto.

(c)                                  Qualified Income Offset. In the event a Partner unexpectedly receives any adjustments, allocations or distributions described in Regulation Section 1.704-l(b)(2)(ii)(d)(4), (5), or (6), and such Partner, thereafter, has an Adjusted Capital Account Deficit, items of Partnership income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate the Adjusted Capital Account Deficit as quickly as possible. This Section 11.2(c) is intended to constitute a “qualified income offset” under Regulation Section 1.704-l(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(d)                                 Nonrecourse Deductions. Nonrecourse Deductions for any fiscal year or other applicable period shall be specially allocated to the Partners, pro rata in accordance with their relative Loss Ratios. For purposes of determining the Partners’ shares of Nonrecourse Liabilities of the Partnership as provided under Section 1.752-3 of the Regulations, the Partners’ interests in Company profits shall be deemed to be in accordance with their relative Loss Ratios.

(e)                                  Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any fiscal year or other applicable period shall be specially allocated to the Partner that bears the economic risk of loss for the debt (i.e., the partner nonrecourse debt) in respect of which such Partner Nonrecourse Deductions are attributable (as determined under Regulation Section 1.704-2(b)(4) and (i)(l)).

(f)                                   Section 754 Basis Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Sections 732, 734 or 743 of the Code is required, pursuant to Regulation Section 1.704-l(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to said section of the Regulations.

11.3                        Curative Allocations. Notwithstanding any other provisions of this Section 11 to the contrary (other than the Regulatory Allocations, as defined below), the allocations .(the “Regulatory Allocations”) set forth in Section 11.2 (save subparagraphs (d) and (f)) shall be taken into account in allocating other items of income, gain, loss, and deduction among the Partners so that, to the extent possible, the cumulative net amount of allocations of Company items under this Section 11 (excepting Section 11.4) shall be equal to the net amount that would have been allocated to each Partner if the Regulatory Allocations had not occurred. This Section 11.3 is intended to minimize to the extent possible and to the extent necessary any economic distortions which may result from application of Section 1.704-l(b) of the Regulations and shall be interpreted in a manner consistent therewith.

11.4                        Tax Allocations.

(a)                                 Generally. Subject to paragraphs (b) and (c) hereof, items of income, gain, loss, deduction and credit to be allocated for income tax purposes (collectively, “Tax Items”) shall be allocated among the Partners on the same basis as their respective book items.

(b)                                 Sections 1245/1250 Recapture.  If any portion of gain from the sale of property is treated as gain which is ordinary income by virtue of the application of Code Sections 1245 or 1250 (“Affected Gain”), then (A) such Affected Gain shall be allocated among the Partners in the same proportion that the depreciation and amortization deductions giving rise to the Affected Gain were allocated and (B) other Tax Items of gain of the same character that would have been recognized, but for the application of Code Sections 1245 and/or 1250, shall be allocated away from those Partners who are allocated Affected Gain pursuant to Clause (A) so that, to the extent possible, the other Partners are allocated the same amount, and type, of capital gain that would have been allocated to them had Code Sections 1245 and/or 1250 not applied. For purposes hereof, in order to determine the proportionate allocations of depreciation and amortization deductions for each fiscal year or other applicable period, such deductions shall be deemed allocated on the same basis as net profit and net loss for such respective period.

(c)                                  Allocations Respecting Section 704(c) and Revaluations: Curative Allocations Resulting from the Ceiling Rule. Notwithstanding paragraph (b) hereof, Tax Items with respect to Partnership property that is subject to Code Section 704(c) and/or Regulation Section 1.704-l(b)(2)(iv)(f) (collectively “Section 704(c) Tax Items”) shall, to the extent so required, be allocated in accordance with said Code section and/or Regulation Section 1.704-3, as the case may be.
