provisions and the following allocations shall be made in the following order:

to such Partner's share of the net decrease in Partnership Minimum Gain,
determined in accordance with Treas. Reg. (S) 1.704-2(g). Allocations pursuant
to the previous sentence shall be made in proportion to the respective amounts
required to be allocated to each Partner pursuant thereto. The items to be so
allocated shall be determined in accordance with Treas. Reg. (S)(S)
1.704-2(f)(6) and 1.704-2(j)(2). This Section 5.2(a) is intended to comply with

who has a share of the Partner Nonrecourse Debt Minimum Gain attributable to

Reg. (S) 1.704-2(i)(5), shall be specially allocated items of Partnership income
and gain for such fiscal year (and, if necessary, subsequent fiscal years) in an
amount equal to such Partner's share of the net decrease in Partner Nonrecourse
Debt Minimum Gain, determined in accordance with Treas. Reg. (S) 1.704-2(i)(4).
Allocations pursuant to the previous sentence shall be made in proportion to the
respective amounts required to be allocated to each Partner pursuant thereto.
The items to be so allocated shall be determined in accordance with Treas.
Reg. (S)(S) 1.704-2(i)(4) and 1.704-2(j)(2). This Section 5.2(b) is intended to
comply with the minimum gain chargeback requirement in Treas.
Reg. (S) 1.704-2(i)(4) and shall be interpreted consistently therewith.

(c) Qualified Income Offset. In the event any Limited Partner
unexpectedly receives any adjustments, allocations, or distributions described
in Treas. Reg. (S)(S) 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or
1.704-1(b)(2)(ii)(d)(6), items of Partnership income and gain shall be specially
allocated to such Limited Partner in an amount and manner sufficient to
eliminate, to the extent required by the Treasury Regulations, the Adjusted
Capital Account Deficit of such Limited Partner as quickly as possible, provided
that an allocation pursuant to this Section 5.2(c) shall be made only if and to
the extent that such Limited Partner would have an Adjusted Capital Account
Deficit after all other allocations provided for in this Article V have been
tentatively made as if this Section 5.2(c) were not in the Agreement.

(d) Gross Income Allocation. In the event any Limited Partner has a
deficit Capital Account at the end of any fiscal year which is in excess of the
amount such Limited Partner is obligated to restore pursuant to any provision of
this Agreement or deemed obligated

to restore pursuant to the penultimate sentences of Treas. Reg. (S)(S)
1.704-2(g)(1) and 1.704-2(i)(5), each such amount of such excess as quickly as
possible, provided that an allocation pursuant to this Section 5.2(d) shall be
made only if and to the extent that such Limited Partner would have a deficit
Capital Account after all other allocations provided for in this Article V have
been made as if Section 5.2(c) hereof and this Section 5.2(d) were not in the
Agreement.

(e) Partner Nonrecourse Deductions. Any Partner Nonrecourse Deductions
for any fiscal year shall be allocated to the Partner who bears the economic
risk of loss with respect to the Partner Nonrecourse Debt to which such Partner
Nonrecourse Deductions are attributable in accordance with Treas.
Reg. (S) 1.704-2(i)(1).

(f) Nonrecourse Deductions. Nonrecourse Deductions for any fiscal year
shall be allocated to the Partners in accordance with their Partnership
Percentages.

(g) Section 754 Adjustments. To the extent an adjustment to the

(S) 743(b) is required pursuant to Treas. Reg. (S) 1.704-1(b)(2)(iv)(m)(2) or
Treas. Reg. (S) 1.704-1(b)(2)(iv)(m)(4) to be taken into account in determining
Capital Accounts as the result of a distribution to a Partner in complete
liquidation of its Partnership Interest, the amount of such adjustment to
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
accordance with their interests in the Partnership in the event Treas. Reg. (S)
1.704.1(b)(2)(iv)(m)(2) applies, or to the Partner to whom such distribution was
made in the event Treas. Reg. (S) 1.704-1(b)(2)(iv)(m)(4) applies.

(h) Curative Allocations. The allocations set forth above in Sections
5.2(a) through (g) (the "Regulatory Allocations") are intended to comply with
certain requirements of the Treasury Regulations. It is the intent of the
Partners that, to the extent possible, all Regulatory Allocations shall be
offset either with other Regulatory Allocations or with special allocations of
other items of Partnership income, gain, loss or deduction pursuant to this
Section 5.2(h). Therefore, notwithstanding any other provisions of this Article
V (other than the Regulatory Allocations), the General Partner shall make such
offsetting special allocations of Partnership income, gain, loss or deduction in
whatever manner it determines appropriate so that, after such offsetting
allocations are made, each Partner's Capital Account balance is, to the extent
possible, equal to the Capital Account balance such Partner would have had if
the Regulatory Allocations were not part of this Agreement and all Partnership
items were allocated pursuant to Article V without regard to the Regulatory
Allocations.

5.3 Other Allocation Rules.

(a) For purposes of determining the Profits, Losses, or any other
items allocable to any period, Profits, Losses, and any such other items shall
be determined on a daily, monthly or other basis, as determined by the General
Partner using any permissible method under Code (S) 706 and the Treasury
Regulations thereunder.

(b) Except as otherwise provided in this Agreement, all items of
Partnership income, gain, loss, deduction and other allocations not otherwise
provided for shall be divided among the Partners in the same proportions as they
share Profits or Losses, as the case may be, for such year.

(c) The Partners are aware of the income tax consequences of the
allocations made by this Article V and hereby agree to be bound by the
provisions of this Article V in reporting their shares of Partnership income and
loss for income tax purposes.

The costs of liquidation shall be borne as a Partnership expense. Until final
distribution, the liquidator shall continue to operate the Partnership Assets
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 shall cause a proper accounting to be made by

liabilities, and operations through the last day of the calendar month in which
the dissolution shall occur or the final liquidation shall be completed, as

limitation, the establishment of a cash escrow fund for contingent liabilities
in such amount and for such term as the liquidator may reasonably determine);
and

(i) the liquidator may sell any or all Partnership Assets, and
any resulting gain or loss from each sale shall be computed and
allocated to the Capital Accounts of the Partners in accordance with
Article V and Section 4.3 hereof:

(ii) with respect to all Partnership Assets that have not been
sold, the fair market value of such property shall be determined and
the Capital Accounts of the Partners shall be adjusted in accordance
with Section 4.3 to reflect the manner in which the unrealized income,
gain, loss and deduction inherent in such property (that has not been
reflected in the Capital Accounts previously) would be allocated under
Article V and Section 4.3 among the Partners if there were a taxable
disposition of such property for the fair market value of such
property on the date of their distribution; and

(iii) Partnership Assets shall be distributed among the Partners
in accordance with the positive Capital Account balances of the

of the taxable year of the Partnership during which the liquidation of
the Partnership occurs (or, if later, on or before the 90th day after
the date of such liquidation).

All distributions in kind to the Partners shall be made subject to the liability
of each distributee for costs, expenses, and liabilities theretofore incurred or
for which the Partnership shall have committed prior to the date of termination
and such costs, expenses, and liabilities shall be allocated to such distributee
pursuant to this Section 12.1. Subject to the provisions of Section 12.2, the
distribution of cash and/or property to a Partner in accordance with the
provisions of

this Section 12.1 shall constitute a complete return to the Partner of its
Capital Contributions and a complete distribution to the Partner of its interest
in the Partnership and all the Partnership Assets and shall constitute a
compromise to which all Partners have consented within the meaning of Section
5.02(d) of the Act. To the extent that a Partner shall return funds to the
Partnership, it shall have no claim against any other Partner for the same.

12.2 Compliance with Timing Requirements of Regulations. In the event the
Partnership is "liquidated" within the meaning of Treas. Reg. (S)
1.704-1(b)(2)(ii)(g), (i) distributions shall be made pursuant to the Article
XII to the Partners who have positive Capital Accounts in compliance with Treas.
Reg. (S) 1.704-(b)(2)(ii)(b)(2), and (ii) if any General Partner's Capital
Account has a deficit balance (after giving effect to all contributions,
distributions and allocations for all fiscal years, including the fiscal year
during which liquidation occurs), such General Partner shall contribute to the
capital of the Partnership the amount necessary to restore such deficit balance
to zero incompliance with Treas. Reg. (S) 1.704-1(b)(2)(ii)(b)(3). If any
Limited Partner has a deficit balance in its Capital Account (after giving
effect to all contributions, distributions, and allocations for all fiscal
years, including the fiscal year during which such liquidation occurs), such
Limited Partner shall have no obligation to make any contribution to the capital
of the Partnership with respect to such deficit, and such deficit shall not be
considered a debt owed to the Partnership or to any other Person for any purpose
whatsoever.

Partnership Assets as provided herein, the Partnership shall be terminated, and

as may be necessary to terminate the Partnership.
