ALLOCATIONS AND DISTRIBUTIONS

1. Allocations

(a) Net Profits. Except as otherwise provided in this Article 7, Net Profits of the Company shall be allocated to the Members in accordance with their Percentage Interests.

(b) Net Losses. Except as otherwise provided in this Article 7, Net Losses of the Company shall be allocated to the Members in accordance with their Percentage Interests.

(i) Section 794(c) Allocation. Any income, gain, loss and deduction with respect to any property (other than cash) that has been contributed by a Member to the capital of the Company, that is deemed to have been contributed to the capital of the Company under Section 708 of the Code and the regulations promulgated thereunder, or that has been revalued in accordance with Treas. Reg. § 1.704-1(b)(2)(iv)(f) and which is required to be allocated to the Members for income tax purposes under Section 704(c) of the Code or Treas. Reg. § 1.704-1(b)(2)(iv)(f) so as to take into account the variation between the tax basis of such property and its agreed upon fair market value at the time of its contribution or revaluation, as the case may be, shall be allocated to the Members solely for income tax purposes in the manner so required.

(ii) Qualified Income Offset. In the event any Member, in such capacity, unexpectedly receives any adjustments, allocations or distributions described in Treas. Reg. §§ 1.704- 1 (b)(2)(ii)(d)(4), (5) or (6), that cause or increase an Adjusted Capital Account Deficit of such Member, items of Company income and gain shall be specially allocated to such Member in an amount and manner sufficient to eliminate to the extent required by the Treas. Rep., the Adjusted Capital Account Deficit of such Member as quickly as possible. This Article 7.1(c)(ii) is intended to comply with the qualified income offset provision of Treas. Reg. § 1.7041(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(iii) Minimum Gain and Member Nonrecourse Debt Minimum Chargeback. Notwithstanding any provision hereof to the contrary, any item of Company income or gain for any Fiscal Year (or any portion of any such item) that is required to be allocated to the Members under Treas. Regs. §§ 1.704-2(f) or 1.7042(i)(4) shall be allocated to the Members for such Fiscal Year in the manner so required by such regulations.

(iv) Limitation of Deduction and Loss Allocation. To the extent that any Member has or would have as a result of an allocation of Net Loss, an Adjusted Capital Account Deficit, such amount of Net Loss shall be allocated to the other Members in accordance with Article 7.1(b), but in a manner which will not produce an Adjusted Capital Account Deficit as to such Members. To the extent such allocation would result in all Members having Adjusted Capital Account Deficits, such Net Loss shall be allocated in accordance with Article 7.1(b). Any allocations of Net Loss pursuant to this Article 7.1(c)(iv) shall be reversed with a corresponding amount of Net Profit in subsequent years.

(d) Tax Allocations.

(i) Except as otherwise provided for in this Article 7.1(d), for federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Members in the same manner as its correlative item' of "book" income, gain, loss or deduction is allocated pursuant to Articles 7.1(a), 7.1(b) and 7.1(c) above.

(ii) In accordance with Code §§ 704(b) and 704(c) and the Treas. Rep. thereunder, income, gain, loss and deduction with respect to any property contributed to the Company, shall solely for federal income tax purposes be allocated among the Members so as to take into account any variation between the adjusted basis of such property to the Company for federal income tax purposes and the initial Gross Asset Value. If the Gross Asset Value of any Company asset is adjusted as described in the definition of Gross Asset Value, subsequent allocations of income, gain, loss and deduction with respect to such Company asset shall take into account any variation between the adjusted basis of such Company asset for federal income tax purposes and its Gross Asset Value in the same manner as under Code § 704(c) and the Treas. Regs. thereunder. In furtherance of the foregoing, with respect to all Company

assets, the Manager shall choose any permissible method under Treas. Reg. § 1.704-3. Allocations pursuant to this Article 7.1(d)(ii) are solely for purposes of federal, state and local taxes and shall not affect, or in any way be taken into account in computing any Member's Capital Account or share of Net Profits, Net Losses, other items or distributions pursuant to any provision of this Agreement.

(iii) Tax Credits. All tax credits shall be allocated among the Members in accordance with applicable law.

2. Distributions.

(a) To the extent that the Company has adequate Distributable Cash and may do so in accordance with all applicable law, the Company shall distribute to the Members, in respect of each Fiscal Year, by the sixtieth (60^th) day of the following Fiscal Year, such Distributable Cash, to the Members in accordance with their Percentage Interests.

(b) For purposes of distributions of the Company's property in kind, such property shall be valued at its Gross Asset Value as of the date of distribution and the amount of any gain or loss that would be realized by the Company if it were to sell such property at such Gross Asset Value shall be allocated to the Members in accordance with the requirements of the Code and, to the extent such allocation does not violate the Code, this Agreement.

(c) Limitations on Distributions. No distribution pursuant to Article 7.2 or otherwise shall be paid if, after the distribution is made, (a) the Company would be unable to pay its debts as they become due, or (b) liabilities of the Company (other than liabilities to Members on account of their Capital Contributions and liabilities for which creditors' recourse is limited to specific assets of the Company) would exceed the fair value of the Company's assets (net of any liabilities to which such property may be subject).

3. Withholding. The Company may withhold from any distribution made pursuant to this Agreement, and may pay over to the appropriate federal, state or local governmental authority, any amounts required to be withheld pursuant to the Code or provisions of applicable state or local law. All amounts withheld pursuant to the preceding sentence in connection with a distribution to any Member to satisfy a tax imposed upon such Member shall be treated as an amount distributed to such Member for all purposes of this Agreement.
