                  (iii) Any income, gain or loss attributable to the taxable
         disposition of any Partnership property shall be determined as if the
         adjusted basis of such property as of such date of disposition were
         equal in amount to the Partnership's Carrying Value with respect to
         such property as of such date.

                  (iv) In accordance with the requirements of Section 704(b) of
         the Code, any deductions for depreciation, cost recovery or
         amortization attributable to any Contributed Property shall be
         determined as if the adjusted basis of such property on the date it was
         acquired by the Partnership were equal to the Agreed Value of such
         property. Upon an adjustment pursuant to Section 4.4(d) to the Carrying
         Value of any Partnership property subject to depreciation, cost
         recovery or amortization, any further deductions for such depreciation,
         cost recovery or amortization attributable to such property shall be
         determined (A) as if the adjusted basis of such property were equal to
         the Carrying Value of such property immediately following such
         adjustment and (B) using a rate of depreciation, cost recovery or
         amortization derived from the same method and useful life (or, if
         applicable, the remaining useful life) as is applied for federal income
         tax purposes; provided, however, that, if the asset has a zero adjusted
         basis for federal income tax purposes, depreciation, cost recovery or
         amortization deductions shall be determined using any reasonable method
         that the General Partner may adopt.

                  (v) If the Partnership's adjusted basis in depreciable or cost
         recovery property is reduced for federal income tax purposes pursuant
         to Section 48(q) (1) or 48(q)(3) of the Code, the amount of such
         reduction shall, solely for purposes hereof, be deemed to be an
         additional depreciation or cost recovery deduction in the year such
         property is placed in service and shall be allocated among the Partners
         pursuant to Section 5.1. Any restoration of such basis pursuant to
         Section 48(q) (2) of the Code shall, to the extent possible, be
         allocated in the same manner to the Partners to whom such deemed
         deduction was allocated.

         (c) A transferee of a Partnership Interest shall succeed to a pro rata
portion of the Capital Account of the transferor relating to the Partnership
Interest so transferred.

         (d) (i) Consistent with the provisions of Treasury Regulation Section
1.704-1(b)(2)iv)(f), on an issuance of additional Partnership Interests for cash
or Contributed Property, the Capital Accounts of all Partners and the Carrying
Value of each Partnership property immediately prior to such issuance shall be
adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss
attributable to such Partnership Property, as if such Unrealized Gain or
Unrealized Loss had been recognized on an actual sale of each such Property
immediately prior to such issuance and had been allocated to the Partners at
such time pursuant to Section 5.1. In determining such Unrealized Gain or
Unrealized Loss, the aggregate cash amount and fair market value of all
Partnership assets (including, without limitation, cash or cash equivalents)
immediately prior to the issuance of Partnership interests shall be determined
by the General Partner using such reasonable method of valuation as it may
adopt; provided however, the General Partner, in arriving at such valuation must
take into account the Limited Partner


                                      -12-
<PAGE>


Equity Value and the General Partner Equity Value, at such time. The General
Partner shall allocate such aggregate value among the assets of the Partnership
(in such manner as it determines in its sole discretion to be reasonable) to
arrive at a fair market value for individual properties.

         (ii) In accordance with Treasury Regulation Section 1.704-1(b) (2) (iv)
(f), immediately prior to any actual or deemed distribution to a Partner of any
Partnership property (other than a distribution of cash that is not in
redemption or retirement of a Partnership Interest), the Capital Accounts of all
Partners and the Carrying Value of each Partnership property shall be adjusted
upward or downward to reflect any Unrealized Gain or Unrealized Loss
attributable to such Partnership property, as if such Unrealized Gain or
Unrealized Loss had been recognized in a sale of such property immediately prior
to such distribution for an amount equal to its fair market value, and had been
allocated to the Partners, at such time, pursuant to Section 5.1. Any Unrealized
Gain or Unrealized Loss attributable to such property shall be allocated in the
same manner as Net Termination Gain or Net Termination Loss pursuant to Section
5.1(c); provided, however, that, in making any such allocation, Net Termination
Gain or Net Termination Loss actually realized shall be allocated first. In
determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount
and fair market value of all Partnership assets (including, without limitation,
cash or cash equivalents) immediately prior to a distribution shall be
determined and allocated by the Liquidator using such reasonable methods of
valuation as it may adopt.

         4.5 Interest. No interest shall be paid by the Partnership on Capital
Contributions or on balances in Partners' Capital Accounts.

         4.6 No Withdrawal. No Partner shall be entitled to withdraw any part of
its Capital Contributions or its Capital Account or to receive any distribution
from the Partnership, except as provided herein.

         4.7 Loans from Partners. Loans by a Partner to the Partnership shall
not constitute Capital Contributions. If any Partner shall advance funds to the
Partnership in excess of the amounts required hereunder to be contributed by it
to the capital of the Partnership, the making of such excess advances shall not
result in any increase in the amount of the Capital Account of such Partner. The
amount of any such excess advances shall be a debt obligation of the Partnership
to such Partner and shall be payable or collectible only out of the Partnership
assets in accordance with the terms and conditions upon which such advances are
made.

                           (B) Second, 100% to the General Partner and the

         Partnership Minimum Gain during any Partnership taxable period, each
         Partner shall be allocated items of Partnership income and gain for
         such period (and, if necessary, subsequent periods) in proportion to,
         and to the extent of, an amount equal to the greater of (A) the portion
         of such Partner's share of the net decrease in Partnership Minimum Gain

         5.1(d)(i) is intended to comply with the Partnership Minimum Gain
         chargeback requirement in Treasury Regulation Section 1.704-2(f) and
         shall be interpreted consistently therewith.

                  (ii) Chargeback of Minimum Gain Attributable to Partner
         Nonrecourse Debt. Notwithstanding the other provisions of this Section
         5.1 (other than Section 5.1(d)(i)), if there is a net decrease in
         Minimum Gain Attributable to Partner Nonrecourse Debt during any
         Partnership taxable period, any Partner with a share of Minimum Gain
         Attributable to Partner Nonrecourse Debt at the beginning of such
         taxable period shall be allocated items of Partnership income and gain
         for such period (and, if necessary, subsequent periods) in proportion
         to, and to the extent of, an amount equal to the greater of (A) the
         portion of such Partner's share of the net decrease in the Minimum Gain
         Attributable to Partner Nonrecourse Debt that is allocable (in
         accordance with the principles set forth in Treasury Regulation Section
         1.704-2(i)) to the disposition of Partnership property subject to such
         Partner Nonrecourse Debt or (B) the deficit balance in such Partner's
         Adjusted Capital Account at the end of such taxable period (modified,
         as appropriate, by Treasury Regulation Section 1.704-2(i)). The items
         to be so allocated shall be determined in a manner consistent with the
         principles of Treasury Regulation Sections 1.704-2(i)(4) and
         1.704-2(j)(2) and, for purposes of this Section 5.1(d), each Partner's
         Adjusted Capital


                                      -15-
<PAGE>


         Account balance shall be determined, and the allocation of income or
         gain required hereunder shall be effected, prior to the application of
         any other allocations pursuant to this Section 5.1(d), other than
         Section 5.1(d)(i), with respect to such taxable period. This Section
         5.1(d) (ii) is intended to comply with the chargeback of items of
         income and gain requirement in Treasury Regulation Section 1.704-2(i)
         and shall be interpreted consistently therewith.

                  (iii) Qualified Income Offset. Except as provided in Sections
         5.1(d)(i) and 5.1(d) (ii), in the event any Partner unexpectedly
         receives any adjustments, allocation or distributions described in
         Treasury Regulation Section 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 specifically allocated to such Partner in an
         amount and manner sufficient to eliminate, to the extent required by
         the Treasury Regulations, the deficit balance, if any, in its Adjusted
         Capital Account created by such adjustments, allocations or
         distributions as quickly as possible; provided, that an allocation
         pursuant to this Section 5.1(d) (iii) shall be made only if and to the
         extent that such partner would have a deficit balance in its Adjusted
         Capital Account after all other allocations provided in this Section
         5.1 have been tentatively made as if this Section 5.1(d) (iii) were not
         in this Agreement.

                  (iv) Gross Income Allocations. In the event any Partner has a
         deficit balance in its Capital Account at the end of any Partnership
         taxable Period that is in excess of the sum of (A) the amount such
         Partner is obligated to restore pursuant to any provision of this
         Agreement and (B) the amount such Partner is deemed to be obligated to
         restore pursuant to the penultimate sentences of Treasury Regulation
         Sections 1.704-2(g)(i) and 1.704-2(i)(5), such Partner shall be
         specially allocated items of Partnership gross income and gain in the
         amount of such excess as quickly as possible; provided, that an
         allocation pursuant to this Section 5.1(d) (iv) shall be made only if
         and to the extent that such Partner would have a deficit Capital
         Account in excess of such sum after all other allocations provided for
         in this Section 5.1 have been tentatively made as if Section 5.1(d)
         (iii) and this Section 5.1(d)(iv) were not in this Agreement.

                  (v) Nonrecourse Deductions. Nonrecourse Deductions for any
         taxable period shall be allocated to the Partners in the same ratios
         that Net Income or Net Losses, as the case may be, is allocated for the
         taxable year. If the General Partner determines in its good faith
         discretion that the Partnership's Nonrecourse Deductions must be
         allocated in a different ratio to satisfy the safe harbor requirements
         of the Treasury Regulations promulgated under Section 704(b) of the
         Code, the General Partner is authorized, upon notice to the Limited
         Partners, to revise the prescribed ratio to the numerically closest
         ratio that does satisfy such requirements.

                  (vi) Partner Nonrecourse Deductions. Partner Nonrecourse
         Deductions for any taxable period shall be allocated 100% to the
         Partner that bears the Economic Risk of Loss with respect to the
         Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions
         are attributable in accordance with Treasury Regulation Section
         1.704-1T(b)(4)(iv)(h). If more than one Partner bears the Economic Risk
         of Loss with respect to a Partner Nonrecourse Debt, such Partner
         Nonrecourse Deductions attributable thereto shall be allocated between
         or among such Partners in accordance with the ratios in which they
         share such Economic Risk of Loss.


                                      -16-
<PAGE>


                  (vii) Nonrecourse Liabilities. The Partners agree that
         Nonrecourse Liabilities of the Partnership in excess of the sum of (A)
         the amount of Partnership Minimum Gain and (B) the total amount of
         Nonrecourse Built-in Gain shall be allocated among the Partners in
         accordance with their respective Percentage Interests.

                  (viii) Code Section 754 Adjustments. To the extent an
         adjustment to the adjusted tax basis of any Partnership asset pursuant
         to Section 734(b) or 743(b) of the Code is required, pursuant to
         Treasury Regulation Section 1.704-1(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 item of 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
         such Section of the Treasury Regulations.

                  (ix) Curative Allocation. (A) Notwithstanding any other
         provision of this Section 5.1, other than the Required Allocation
         provisions, the Required Allocations shall be taken into account in
         making the Agreed Allocations so that, to the extent possible, the net
         amount of items of income, gain, loss and deduction allocated to each
         Partner pursuant to the Required Allocations and the Agreed
         Allocations, together, shall be equal to the net amount of such items
         that would have been allocated to each such Partner under the Agreed
         Allocations had the Required Allocations and this Curative Allocation
         not otherwise been provided in this Section 5.1. Notwithstanding the
         preceding sentence, Required Allocations relating to (l) Nonrecourse
         Deductions shall not be taken into account except to the extent that
         there has been a decrease in Partnership Minimum Gain and (2) Partner
         Nonrecourse Deductions shall not be taken into account except to the
         extent that there has been a decrease in Minimum Gain Attributable to
         Partner Nonrecourse Debt. Allocations pursuant to this Section 5.1(d)
         (ix) (A) shall only be made with respect to Required Allocations to the
         extent the General Partner reasonably determines that such allocations
         will otherwise be inconsistent with the economic agreement among the
         Partners. Further, allocations pursuant to this Section 5.1(d) (ix) (A)
         shall be deferred with respect to allocations pursuant to clauses (l)
         and (2) hereof to the extent the General Partner reasonably determines
         that such allocations are likely to be offset by subsequent Required
         Allocations.

                  (B) The General Partner shall have reasonable discretion, with
         respect to each taxable period, to (1) apply the provisions of Section
         5.1(d) (ix) (A) in whatever order is most likely to minimize the
         economic distortions that might otherwise result from the Required
         Allocations, and (2) divide all allocations pursuant to Section 5 1(d)
         (ix) (A) among the Partners in a manner that is likely to minimize such
         economic distortions.

         5.2 Allocations for Tax Purposes.

         (a) Except as otherwise provided herein, for federal income tax
purposes, each item of income, gain, loss and deduction shall be allocated among
the Partners in the same manner as its correlative item of "book" income, gain,
loss or deduction is allocated pursuant to Section 5.1.

         (b) In an attempt to eliminate Book-Tax Disparities attributable to a
Contributed Property or Adjusted Property, items of income, gain, loss,
depreciation, amortization and cost recovery deductions shall be allocated for
federal income tax purposes among the Partners as follows:

                  (i) (A) In the case of a Contributed Property, such items
         attributable thereto shall be allocated among the Partners in the
         manner provided under Section 704(c) of the Code that takes into
         account the variation between the Agreed Value of such property and its
         adjusted basis at the time of contribution; and (B) except as otherwise
         provided in Section 5.2(b) (iv), any item of Residual Gain or Residual
         Loss attributable to a Contributed Property shall be allocated among
         the Partners in the same manners as its correlative items of "book"
         gain or loss is allocated pursuant to Section 5.1.

                  (ii) (A) In the case of an Adjusted Property, such items shall
         (1) first, be allocated among the Partners in a manner consistent with
         the principles of Section 704(c) of the Code to take into account the
         Unrealized Gain or Unrealized Loss attributable to such property and
         the allocators thereof pursuant to Section 4.4(d)(i) or (ii), and (2)
         second, in the event such property was originally a Contributed
         Property, be allocated among the Partners in a manner consistent with
         Section 5.2(b) (i) (A); and (B) except as otherwise provided in Section
         5.2(b) (iv), any item of Residual Gain or Residual Loss attributable to
         an Adjusted Property shall be allocated among the Partners in the same
         manner as its correlative item of "book" gain or loss is allocated
         pursuant to Section 5.1.

                  (iii) Except as otherwise provided in Section 5.2(b) (iv), all
         other items of income, gain, loss and deduction shall be allocated
         among the Partners in the same manner as their correlative item of
         "book" gain or loss is allocated pursuant to Section 5.1.

                  (iv) Any items of income, gain, loss or deduction otherwise
         allocable under Section 5.2(b)(i)(B), 5.2(b) (ii) (B) or 5.2(b) (iii)
         shall be subject to allocation by the General Partner in a manner
         designed to eliminate, to the maximum extent possible, Book-Tax
         Disparities in a Contributed Property or Adjusted Property otherwise
         resulting from the application of the "ceiling" limitation (under
         Section 704(c) of the Code or Section 704(c) principles) to the
         allocations provided under Section 5.2(b) (i) (A) or 5.2(b) (ii) (A)

         (c) For the proper administration of the Partnership and for the
preservation of uniformity of the Units of the Investor Partnership (or any
class or classes thereof), the General Partner shall have sole discretion to (i)
adopt such conventions as it deems appropriate in determining the amount of
depreciation, amortization and cost recovery deductions; (ii) make special
allocations for federal income tax purposes of income (including, without
limitation, gross income) or deductions; and (iii) amend the provisions of this
Agreement as appropriate (x) to reflect the proposal or promulgation of Treasury
Regulations under Section 704(b) or Section


                                      -18-
<PAGE>


704(c) of the Code or (y) otherwise to preserve or achieve uniformity of the
Units of the Investor Partnership (or any class or classes thereof). The General
Partner may adopt such conventions, make such allocations and make such
amendments to this Agreement as provided in this Section 5.2(c) only if such
conventions, allocations or amendments would not have a material adverse effect
on the Partners, the holders of any class or classes of Units of the Investor
Partnership issued and outstanding or the Partnership, and if such allocations
are consistent with the principles of Section 704 of the Code.

         (d) The General Partner in its sole discretion may determine to
depreciate the portion of an adjustment under Section 743(b) of the Code
attributable to unrealized appreciation in any Adjusted Property (to the extent
of the unamortized Book-Tax Disparity) using a predetermined rate derived from
the depreciation method and useful life applied to the Partnership's common
basis of such property, despite the inconsistency of such approach with Treasury
Regulation Section 1.167(c)-1(a) (6). If the General Partner determines that
such reporting position cannot reasonably be taken, the General Partner may
adopt a depreciation convention under which all purchasers acquiring Units of
the Investor Partnership in the same month would receive depreciation, based
upon the same applicable rate as if they had purchased a direct interest in the
Partnership's property. If the General Partner chooses not to utilize such
aggregate method, the General Partner may use any other reasonable depreciation
convention to preserve the uniformity of the intrinsic tax characteristics of
any Units of the Investor Partnership that would not have a material adverse
effect on the Limited Partners or the Record Holders of any class or classes of
Units of the Investor Partnership.

         (e) Any gain allocated to the Partners upon the sale or other taxable
disposition of any Partnership asset shall, to the extent possible, after taking
into account other required allocations of gain pursuant to this Section 5.2 be
characterized as Recapture Income in the same proportions and to the same extent
as such Partners (or their predecessors in interest) have been allocated any
deductions directly or indirectly giving rise to the treatment of such gains as
Recapture Income.

         (f) All items of income, gain, loss, deduction and credit recognized by
the Partnership for federal income tax purposes and allocated to the Partners in
accordance with the provisions hereof shall be determined without regard to any
election under Section 754 of the Code which may be made by the Partnership;
provided, however, that such allocations, once made, shall be adjusted as
necessary or appropriate to take into account those adjustments permitted or
required by Sections 734 and 743 of the Code.

         (g) The General Partner may adopt such methods of allocation of income,
gain, loss or deduction between a transferor and a transferee of a Partnership
Interest as it determines necessary, to the extent permitted or required by
Section 706 of the Code and the regulations or rulings promulgated thereunder.

         5.3 Requirement of Distributions. Within fifty days following the end
of each calendar quarter, an amount equal to 100% of Available Cash with respect
to such quarter (or period) shall be distributed by the Partnership to the
Partners in accordance with their respective Percentage Interests. The
immediately preceding sentence shall not require any distribution of cash if and
to the extent such distribution would be prohibited by applicable law or by any
loan


                                      -19-

agreement, security agreement, mortgage, debt instrument or other agreement or
obligation to which the Partnership is a party or by which it is bound or its
assets are subject.



               ARTICLE VI - MANAGEMENT AND OPERATION OF BUSINESS

         6.1 Management. The General Partner shall conduct, direct and exercise
full control over all activities of the Partnership. Except as otherwise
expressly provided in this Agreement, all management powers over the business

Partner, and the Limited Partner shall have no right of control or management
power over the business and affairs of the Partnership. In addition to the
powers now or hereafter granted a general partner of a limited partnership under
applicable law or which are granted to the General Partner under any other
provision of this Agreement, the General Partner, subject to Section 6.3, shall
have full power and authority to do all things and on such terms as it, in its
sole discretion, may deem necessary or desirable (i) to conduct the business of
the Partnership, to exercise all powers set forth in Section 3.2 and to
effectuate the purposes set forth in Section 3.1, including, without limitation,
(A) the making of any expenditures, the lending or borrowing of money, the
assumption or guarantee of, or other contracting for, indebtedness and other
liabilities, the issuance of evidences of indebtedness and the incurring of any
other obligations and the securing of same by mortgage, deed of trust or other
lien or encumbrance; (B) the making of tax, regulatory and other filings, or
rendering of periodic or other reports to governmental or other agencies having
jurisdiction over the business or assets of the Partnership, (C) the
acquisition, disposition, mortgage, pledge, encumbrance, hypothecation or
exchange of any or all of the assets of the Partnership or the merger or other
combination of the Partnership with or into another Person (the matters
described in this clause (C) being subject, however, to any prior approval that
may be required by Section 6.3); (D) the use of the assets of the Partnership
(including, without limitation, cash on hand) for any purpose consistent with
the terms of this Agreement, including, without limitation, the financing of the
conduct of the operations of the Partnership, the lending of funds to other
Persons and the repayment of obligations of the Partnership; (E) the
negotiation, execution and performance of any contracts, conveyances or other
instruments (including, without limitation, instruments that limit the liability
of the Partnership under contractual arrangements to all or particular assets of
the Partnership, with the other party to the contract to have no recourse
against the General Partner or its assets other than its interest in the
Partnership, even if same results in the terms of the transaction being less
favorable to the Partnership than would otherwise be the case); (F) the
distribution of Partnership cash; (G) the selection and dismissal of employees
and agents (including without limitation, employees having titles such as
"president," "vice president," "secretary" and "treasurer") and agents, outside
attorneys, accountants, consultants and contractors and the determination of
their compensation and other terms of employment or hiring; (H) the maintenance
of such insurance for the benefit of the Partnership and the Partners as it
deems necessary or appropriate; (I) the formation of, or acquisition of an
interest in, and the contribution of property to, any further limited or general
partnerships, joint ventures or other relationships; (J) the control of any
matters affecting the rights and obligations of the Partnership, including,
without limitation, the bringing and defending of actions at law or in equity
and otherwise engaging in the conduct of litigation and the incurring of legal
expense and the settlement of claims and litigation; (K) the indemnification of
any person against liabilities


                                      -20-
<PAGE>


and contingencies to the extent permitted by law; and (L) the undertaking of any
action in connection with the Partnership's participation in the business
activities that may be made available to it (including, without limitation,
contributions or loans of funds by the Partnership in connection with its
participation in such business activities).

         6.2 Certificate of Limited Partnership. The General Partner has caused
the Certificate of Limited Partnership to be filed with the Secretary of State
of the State of Delaware as required by the Delaware Act and shall use all
reasonable efforts to cause to be filed such other certificates or documents as
may be determined by the General Partner in its sole discretion to be reasonable
and necessary or appropriate for the formation, continuation, qualification and
operation of a limited partnership (or a partnership in which the Limited
Partner has limited liability) in the State of Delaware or any other state in
which the Partnership may elect to do business or own property. To the extent
that such action is determined by the General Partner in its sole discretion to
be reasonable and necessary or appropriate, the General Partner shall file
amendments to and restatements of the Certificate of Limited Partnership and do
all things to maintain the Partnership as a limited partnership (or a
partnership in which the Limited Partner has limited liability) under the laws
of the State of Delaware or of any other state in which the Partnership may
elect to do business or own property. Subject to the terms of Section 7.4(a),
the General Partner shall not be required, before or after filing, to deliver or
mail a copy of the Certificate of Limited Partnership, any qualification
document or any amendment thereto to the Limited Partner.

         6.3 Restrictions on General Partner's Authority.

         (a) The General Partner may not, without written approval of the
specific act by the Limited Partner or by other written instrument executed and
delivered by the Limited Partner subsequent to the date of this Agreement, take
any action in contravention of this Agreement, including, without limitation,
(i) any act that would make it impossible to carry on the ordinary business of
the Partnership, except as otherwise provided in this Agreement; (ii) possess
Partnership property, or assign any rights in specific Partnership property, for
other than a Partnership purpose; (iii) admit a Person as a Partner, except as
otherwise provided in this Agreement; (iv) amend this Agreement in any manner,
except as otherwise provided in this Agreement; or (v) transfer its interest as
general partner of the Partnership, except as otherwise provided in this
Agreement.

         (b) Except as provided in Article XIII, the General Partner may not
sell, exchange or otherwise dispose of all or substantially all of the
Partnership's assets in a single transaction or a series of related transactions
(including by way of merger, consolidation or other combination with any other
Person) without the approval of the Limited Partner; provided, however, that
this provision shall not preclude or limit the General Partner's ability to
mortgage, pledge, hypothecate or grant a security interest in all or
substantially all of the Partnership's assets and shall not apply to any forced
sale of any or all of the Partnership's assets pursuant to the foreclosure of,
or other realization upon, any such encumbrance.

         (c) At all times while serving as the general partner of the
Partnership, the General Partner shall not make any dividend or distribution on,
or repurchase any shares of, its stock or take any other action within its
control if the effect of such dividend, distribution, repurchase or


                                      -21-
<PAGE>


other action would be to reduce its net worth below an amount necessary to
receive an Opinion of Counsel that the Partnership will be treated as a
partnership for federal income tax purposes.

         6.4 Reimbursement of the General Partner.

         (a) Except as provided in this Section 6.4 and elsewhere in this
Agreement, the General Partner shall not be compensated for its services as
general partner of the Partnership

         (b) The General Partner shall be reimbursed on a monthly basis, or such
other basis as the General Partner may determine in its sole discretion, for (i)
all direct and indirect expenses it incurs or payments it makes on behalf of the
Partnership (including, without limitation, amounts paid to any Person to
perform services for the Partnership) and (ii) that portion of the General
Partner's or its Affiliates' legal, accounting, investor communications,
utilities, telephone, secretarial, travel, entertainment, bookkeeping,
reporting, data processing, office rent and other office expenses (including,
without limitation, overhead charges), salaries, fees and other compensation and
benefit expenses of employees, officers and directors, other administrative or
overhead expenses and all other expenses, in each such case, necessary or
appropriate to the conduct of the Partnership's business and allocable to the
Partnership or otherwise incurred by the General Partner in connection with
operating the Partnership's business (including, without limitation, expenses
allocated to the General Partner by its Affiliates). The General Partner shall
determine the fees and expenses that are allocable to the Partnership in any
reasonable manner determined by the General Partner in its sole discretion. Such
reimbursements shall be in addition to any reimbursement to the General Partner
as a result of indemnification pursuant to Section 6.7. Notwithstanding the
foregoing grant of authority, expenses for administrative services and overhead
allocated pursuant to this Section 6.4(b) to the Partnership, the Investor
Partnership and the General Partner, considered together, by Duke or its
Affiliates (excluding the General Partner) shall not exceed $25,000 in each
month, unless expressly agreed otherwise.

         (c) The General Partner in its sole discretion and without the approval
of the Limited Partner may propose and adopt on behalf of the Partnership
employee benefit plans (including, without limitation, plans involving the
issuance of Units), for the benefit of employees of the General Partner, the
Partnership or any Affiliate of any of them in respect of services performed,
directly or indirectly, for the benefit of the Partnership.

         6.5 Outside Activities.

         (a) After the Closing Date, the General Partner shall limit its
activities to those required or authorized by this Agreement.

         (b) Except as provided in Section 6.5(a), each Indemnitee is free to
engage in any business, including any business that is in competition with the
business of the Partnership. The General Partner and any other Persons
affiliated with the General Partner may acquire Units or other partnership
securities of the Investor Partnership and shall be entitled to exercise all
rights of an Assignee or limited partner, as applicable, relating to such Units
or partnership securities, as the case may be.

         (c) Without limiting Sections 6.5(a) and 6.5(b), but notwithstanding
anything to the contrary in this Agreement, the competitive activities of
Indemnitees described in the Registration Statement are hereby approved by all
Partners, and it shall not be deemed to be a breach of the General Partner's
fiduciary duty for the General Partner to permit an Indemnitee to engage in a
business opportunity in preference to or to the exclusion of the Partnership.

         6.6 Loans to and from the General Partner; Contracts with Affiliates.

         (a) The General Partner, the Limited Partner or any Affiliates thereof
may lend to the Partnership, and the Partnership may borrow, funds needed or
desired by the Partnership for such periods of time as the General Partner may
determine; provided, however, that neither the General Partner, the Limited
Partner or any of their Affiliates may charge the Partnership interest at a rate
greater than the rate that would be charged the Partnership (without reference
to the General Partner's financial abilities or guarantees) by unrelated lenders
on comparable loans. The Partnership shall reimburse the General Partner, the
Limited Partner or any of their Affiliates, as the case may be, for any costs
(other than any additional interest costs) incurred by it in connection with the
borrowing of funds obtained by the General Partner, the Limited Partner or any
of their Affiliates and loaned to the Partnership.

         (b) The Investor Partnership may lend or contribute to the Partnership,
and the Partnership may borrow, funds on terms and conditions established in the
sole discretion of the General Partner. The foregoing authority shall be
exercised by the General Partner in its sole discretion and shall not create any
right or benefit in favor of the Investor Partnership or any other Person. The
Partnership may not lend funds to the General Partner or any of its Affiliates,
otherwise than for short-term funds management purposes.

         (c) The General Partner may itself, or may enter into an agreement with
any of its Affiliates to, render services to the Partnership. Any service
rendered to the Partnership by the General Partner or any of its Affiliates
shall be on terms that are fair and reasonable to the Partnership; provided,
however, that the requirements of this Section 6.6(c) shall be deemed satisfied
as to any transaction the terms of which are no less favorable to the
Partnership than those generally being provided to or available from unrelated
third parties. The provisions of Section 6.4 shall apply to the rendering of
services described in this Section 6.6(c).

         (d) The Partnership may transfer assets to joint ventures, other
Partnerships, corporations, limited liability companies or other business
entities in which it is or thereby becomes a participant upon such terms and
subject to such conditions as are consistent with this Agreement and applicable
law.

         (e) Neither the General Partner nor any of its Affiliates shall sell,
transfer or convey any property to, or purchase any property from the
Partnership, directly or indirectly, except pursuant to transactions that are
fair and reasonable to the Partnership; provided, however, that the requirements
of this Section 6.6(e) shall be deemed to be satisfied as to any transaction the
terms of which are no less favorable to the Partnership than those generally
being provided to or available from unrelated third parties.


                                      -23-

         (f) The General Partner and its Affiliates will have no obligation to
permit the Partnership or the Investor Partnership to use any facilities of the
General Partner and its Affiliates, except as may be provided in contracts
entered into from time to time specifically dealing with such use, nor shall
there be any obligation on the General Partner or its Affiliates to enter into
such contracts.

         (g) Without limitation of Sections 6.6(a) through 6.6(f), and
notwithstanding anything to the contrary in this Agreement, the existence of the
conflicts of interest described in the Registration Statement under the caption
"Conflicts of Interest and Fiduciary Responsibility" are hereby approved by all
Partners.

         6.7 Indemnification.

         (a) To the fullest extent permitted by law but subject to the
limitations expressly provided in this Agreement, each Indemnitee shall be
indemnified and held harmless by the Partnership from and against any and all
losses, claims, damages, liabilities (joint or several), expenses (including,
without limitation, legal fees and expenses), judgments, fines, settlements and
other amounts arising from any and all claims, demands, actions, suits or
proceedings, whether civil, criminal, administrative or investigative, in which
any Indemnitee may be involved, or is threatened to be involved, as a party or
otherwise, by reason of its status as (i) the General Partner, a Departing
Partner or any of their Affiliates, (ii) an officer, director, employee,
partner, agent or trustee of the General Partner, any Departing Partner or any
of their Affiliates or (iii) a Person serving at the request of the Partnership
in another entity in a similar capacity, provided, that in each case the
Indemnitee acted in good faith, in a manner which such Indemnitee believed to be
in, or not opposed to, the best interests of the Partnership and, with respect
to any criminal proceeding, had no reasonable cause to believe its conduct was
unlawful. The termination of any action, suit or proceeding by judgment, order,
settlement, conviction or upon a plea of nolo contendere, or its equivalent,
shall not create a Presumption that the Indemnitee acted in a manner contrary to
that specified above. Any indemnification pursuant to this Section 6.7 shall be
made only out of the assets of the Partnership.

         (b) To the fullest extent permitted by law, expenses (including,
without limitation, legal fees and expenses) incurred by an Indemnitee in
defending any claim, demand, action, suit or proceeding shall, from time to
time, be advanced by the Partnership prior to the final disposition of such
claim, demand, action, suit or proceeding upon receipt by the Partnership of an
undertaking by or on behalf of the Indemnitee to repay such amount if it shall
be determined that the Indemnitee is not entitled to be indemnified as
authorized in this Section 6.7.

         (c) The indemnification provided by this Section 6.7 shall be in
addition to any other rights to which an Indemnitee may be entitled under any
agreement, pursuant to any vote of the Partners, as a matter of law or
otherwise, both as to actions in the Indemnitees' capacity as (i) the General
Partner, a Departing Partner or an Affiliate thereof, (ii) an officer, director,
employee, partner, agent or Departing Partner or an Affiliate thereof or (iii) a
Person serving at the request of the Partnership in another entity in a similar
capacity, and shall continue as to an Indemnitee who has ceased to serve in such
capacity and as to actions in any other capacity.


                                      -24-
<PAGE>


         (d) The Partnership may purchase and maintain (or reimburse the General
Partner or its Affiliates for the cost of) insurance, on behalf of the General
Partner and such other Person as the General Partner shall determine, against
any liability that may be asserted against or expense that may be incurred by
such Person in connection with the Partnership's activities, whether or not the
Partnership would have the power to indemnify such Person against such
liabilities under the provisions of this Agreement.

         (e) For purposes of this Section 6.7, the Partnership shall be deemed
to have requested an Indemnitee to serve as fiduciary of an employee benefit
plan whenever the performance by it of its duties to the Partnership also
imposes duties on, or otherwise involves services by, it to the plan or
participants or beneficiaries of the plan; excise taxes assessed on an
Indemnitee with respect to an employee benefit plan pursuant to applicable law
shall constitute "fines" within the meaning of Section 6.7(a); and action taken
or omitted by it with respect to an employee benefit plan in the performance of
its duties for a purpose reasonably believed by it to be in the interest of the
participants and beneficiaries of the plan shall be deemed to be for a purpose
which is in, or not opposed to, the best interests of the Partnership.

         (f) In no event may an Indemnitee subject the Limited Partner to
personal liability by reason of the indemnification provisions set forth in this
Agreement.

         (g) An Indemnitee shall not be denied indemnification in whole or in
Part under this Section 6.7 because the Indemnitee had an interest in the
transaction with respect to which the indemnification applies if the transaction
was otherwise permitted by the terms of this Agreement.

         (h) The provisions of this Section 6.7 are for the benefit of the
Indemnitees, their heirs, successors, assigns and administrators and shall not
be deemed to create any rights for the benefit of any other Persons.

         (i) No amendment, modification or repeal of this Section 6.7 or any
provision hereof shall in any manner terminate, reduce or impair the right of
any past, present or future Indemnitee to be indemnified by the Partnership, nor
the obligation of the Partnership to indemnify any such Indemnitee under and in
accordance with the provisions of this Section 6.7 as in effect immediately
prior to such amendment, modification or repeal with respect to claims arising
from or relating to matters occurring, in whole or in part, prior to such
amendment, modification or repeal, regardless of when such claims may arise or
be asserted.

         6.8 Liability of Indemnitees.

         (a) Notwithstanding anything to the contrary set forth in this
Agreement, no Indemnitee shall be liable for monetary damages to the
Partnership, the Limited Partner, or any other Persons who have acquired
interests in the Partnerships, for losses sustained or liabilities incurred as a
result of any act or omission if such Indemnitee acted in good faith.

         (b) Subject to its obligations and duties as General Partner set forth
in Section 6.1(a), the General Partner may exercise any of the powers granted to
it by this Agreement and perform any of the duties imposed upon it hereunder
either directly or by or through its agents, and the


                                      -25-
<PAGE>



General Partner shall not be responsible for any misconduct or negligence on the
part of any such agent appointed by the General Partner in good faith.

         (c) Any amendment, modification or repeal of this Section 6.8 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the liability to the Partnership and the Limited Partner of the
General Partner, its directors, officers and employees under this Section 6.8 as
in effect immediately prior to such amendment, modification or repeal with
respect to claims arising from or relating to matters occurring, in whole or in
part, prior to such amendment, modification or repeal, regardless of when such
claims may arise or be asserted.

         6.9 Resolution of Conflicts of Interest.

         (a) Unless otherwise expressly provided in this Agreement or the
Investor Partnership Agreement, whenever a potential conflict of interest exists
or arises between the General Partner or any of its Affiliates, on the one hand,
and the Partnership, or the Investor Partnership, on the other hand, any
resolution or course of action in respect of such conflict of interest shall be
permitted and deemed approved by the Limited Partner, and shall not constitute a
breach of this Agreement, of the Investor Partnership Agreement, of any
agreement contemplated herein or therein, or of any duty stated or implied by
law or equity, if the resolution or course of action is or, by operation of this
Agreement is deemed to be, fair and reasonable to the Partnership. The General
Partner shall be authorized in connection with its resolution of any conflict of
interest to consider (i) the relative interests of any party to such conflict,
agreement, transaction or situation and the benefits and burdens relating to
such interests (ii) any customary or accepted industry practices and any
customary or historical dealings with a Particular Person; (iii) any applicable
generally accepted accounting or engineering practices or principles; and (iv)
such additional factors as the General Partner determines in its sole discretion
to be relevant, reasonable or appropriate under the circumstances. Nothing
contained in this Agreement, however, is intended to nor shall it be construed
to require the General Partner to consider the interests of any Person other
than the Partnership. In the absence of bad faith by the General Partner, the
resolution, action or terms so made, taken or provided by the General Partner
with respect to such matter shall not constitute a breach of this Agreement or
any other agreement contemplated herein or a breach of any standard of care or
duty imposed herein or therein or under the Delaware Act or any other law, rule
or regulation.

         (b) Whenever this Agreement or any other agreement contemplated hereby
provides that the General Partner or any of its Affiliates is permitted or
required to make a decision (i) in its "sole discretion" or "discretion", that
it deems "necessary or appropriate" or under a grant of similar authority or
latitude, the General Partner or such Affiliate shall be entitled to consider
only such interests and factors as it desires and shall have no duty or
obligation to give any consideration to any interest of, or factors affecting,
the Partnership, the Investor Partnership, the Limited Partner or any holder of
Units, or (ii) in "good faith" or under another express standard, the General
Partner or such Affiliate shall act under such express standard and shall not be
subject to any other or different standards imposed by this Agreement, the
Investor Partnership Agreement, any other agreement contemplated hereby or under
the Delaware Act or any other law, rule or regulation. In addition, any actions
taken by the General Partner consistent with the standards of "reasonable
discretion" set forth in the definition of Available Cash shall not


                                      -26-
<PAGE>


constitute a breach of any duty of the General Partner to the Partnership or the
Limited Partner. The General Partner shall have no duty, express or implied, to
sell or otherwise dispose of any asset of the Partnership, other than in the
ordinary course of business. No borrowing by the Partnership or the approval
thereof by the General Partner shall be deemed to constitute a breach of any
duty of the General Partner to the Partnership or the Limited Partner by reason
of the fact that the purpose or effect of such borrowing is directly or
indirectly to enable the General Partner to receive incentive distributions
pursuant to the Investor Partnership Agreement.

         (c) Whenever a particular transaction, arrangement or resolution of a
conflict of interest is required under this Agreement to be "fair and
reasonable" to any Person, the fair and reasonable nature of such transaction,
arrangement or resolution shall be considered in the context of all similar or
related transactions.

         6.10 Other Matters Concerning the General Partner.

         (a) The General Partner may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, bond, debenture, or other
paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties.

         (b) The General Partner may consult with legal counsel, accountants,
appraisers, management consultants, investment bankers and other consultants and
advisers selected by it, and any act taken or omitted in reliance upon the
opinion (including, without limitation, an Opinion of Counsel) of such Persons
as to matters that such General Partner reasonably believes to be within such
Person's professional or expert competence shall be conclusively presumed to
have been done or committed in good faith and in accordance with such opinion.

         (c) The General Partner shall have the right, in respect of any of its
powers or obligations hereunder, to act through any of its duly authorized
officers and a duly appointed attorney or attorneys-in-fact. Each such attorney
shall, to the extent provided by the General Partner in the power of attorney,
have full power and authority to do and perform each and every act and duty that
is permitted or required to be done by the General Partner hereunder.

         (d) Any standard of care and duty imposed by this Agreement or under
the Delaware Act or any applicable law, rule or regulation shall be modified,
waived or limited as required to permit the General Partner to act under this
Agreement or any other agreement contemplated by this Agreement and to make any
decision pursuant to the authority prescribed in this Agreement so long as such
action is reasonably believed by the General Partner to be in the best interests
of the Partnership.

         6.11 Title to Partnership Assets. Title to Partnership Assets, whether
real, personal or mixed and whether tangible or intangible, shall be deemed to
be owned by the Partnership as an entity, and no Partner, individually or
collectively, shall have any Ownership interest in such Partnership Assets or
any portion thereof. Title to any or all of the Partnership Assets may be held
in the name of the Partnership, the General Partner or one or more nominees, as
the General Partner may determine. The General Partner hereby declares and
warrants that any Partnership Assets for which record title is held in the name
of the General Partner shall be held by the


                                      -27-
<PAGE>


General Partner for the use and benefit of the Partnership in accordance with
the provisions of this Agreement; provided, however, that the General Partner
shall use its reasonable efforts to cause record title to such assets (other
than those assets in respect of which the General Partner determines that the
expense and difficulty of conveyancing makes transfer of record title to the
Partnership impracticable) to be vested in the Partnership as soon as reasonably
practicable. All Partnership Assets shall be recorded as the property of the
Partnership in its books and records, irrespective of the name in which record
title to such Partnership Assets are held.

         6.12 Reliance by Third Parties. Notwithstanding anything to the
contrary in this Agreement, any Person dealing with the Partnership shall be
entitled to assume that the General Partner has full power and authority to
encumber, sell or otherwise use in any manner any and all assets of the
Partnership and to enter into any contracts on behalf of the Partnership, and
such Person shall be entitled to deal with the General Partner as if it were the
Partnership's sole party in interest, both legally and beneficially. The Limited
Partner hereby waives any and all defenses or other remedies that may be
available against such Person to contest, negate or disaffirm any action of the
General Partner in connection with any such dealing. In no event shall any
Person dealing with the General Partner or its representatives be obligated to
ascertain that the terms of this Agreement have been complied with or to inquire
into the necessity or expedience of any act or action of the General Partner or
its representatives. Each and every certificate, document or other instrument
executed on behalf of the Partnership by the General Partner or its
representatives shall be conclusive evidence in favor of any and every Person
relying thereon or claiming thereunder that (a) at the time of the execution and
delivery of such certificate, document or instrument, this Agreement was in full
force and effect, (b) the Person executing and delivering such certificate,
document or instrument was duly authorized and empowered to do so for and on
behalf of the Partnership and (c) such certificate, document or instrument was
duly executed and delivered in accordance with the terms and provisions of this
Agreement and is binding upon the Partnership.



          ARTICLE VII - RIGHTS AND OBLIGATIONS OF THE LIMITED PARTNER

         7.1 Limitation of Liability. The Limited Partner shall have no
liability under this Agreement except as expressly provided in this Agreement or
the Delaware Act.

         7.2 Management of Business. The Limited Partner shall not take part in
the operation, management or control (within the meaning of the Delaware Act) of
the Partnership's business, transact any business in the Partnership's name or
have the power to sign documents for or otherwise bind the Partnership. The
transaction of any such business by the General Partner, any of its Affiliates
or any officer, director, employee, partner, agent or trustee of the General
Partner or any of its Affiliates, in its capacity as such, shall not affect,
impair or eliminate the limitations on the liability of the Limited Partner
under this Agreement.

         7.3 Return of Capital. The Limited Partner shall not be entitled to the
withdrawal or return of his Capital Contribution, except to the extent, if any,
that distributions made pursuant to this Agreement or upon termination of the
Partnership may be considered as such by law and then only to the extent
provided for in this Agreement.

shall have the right, for a purpose reasonably related to the Limited Partner's
interest as a limited partner to the Partnership, upon reasonable demand and at
the Limited Partner's own expense:

                  (i) to obtain true and full information regarding the status

         General Partner, a current list of the name and last known business,
         residence or mailing address of each Partner;

                  (iv) to have furnished to him, upon notification to the
         General Partner, a copy of this Agreement and the Certificate of
         Limited Partnership and all amendments thereto;

                  (v) to obtain true and full information regarding the amount
         of cash and description and statement of the Agreed Value of any other
         Capital Contribution by each Partner and which each Partner has agreed
         to contribute in the future, and the date on which each became a
         Partner; and

                  (vi) to obtain such other information regarding the affairs of
         the Partnership as is just and reasonable.

         (b) Notwithstanding any other provision of this Agreement, the General
Partner may keep confidential from the Limited Partner for such period of time
as the General Partner deems reasonable, any information that the General
Partner reasonably believes to be in the nature of trade secrets or other
information the disclosure of which the General Partner in good faith believes
is not in the best interests of the Partnership or could damage the partnership
or the Investor Partnership or that the Partnership or the Investor Partnership
is required by law or by agreements with third parties to keep confidential.



             ARTICLE VIII - BOOKS, RECORDS, ACCOUNTING AND REPORTS

         8.1 Records and Accounting. The General Partner shall keep or cause to
be kept at the principal office of the Partnership appropriate books and records
with respect to the Partnership business including, without limitation, all
books and records necessary to provide to the Limited Partner any information,
lists and copies of documents required to be provided pursuant to Section
7.4(a). Any books and records maintained by or on behalf of the Partnership in
the regular course of its business, including, without limitation, books of
account and records of Partnership proceedings, may be kept on, or be in the
form of, computer disks, hard disks, punch cards, magnetic tape, photographs,
micrographics or any other information storage device,


                                      -29-
<PAGE>


provided, that the books and records so maintained are convertible into clearly
legible written form within a reasonable period of time. The books of the
Partnership shall be maintained, for financial reporting purposes, on an accrual
basis in accordance with generally accepted accounting principles.

         8.2 Fiscal Year. The fiscal year of the Partnership shall be the
calendar year.



                            ARTICLE IX - TAX MATTERS

         9.1 Preparation of Tax Returns. The General Partner shall arrange for
the preparation and timely filing of all returns of Partnership income, gains,
deductions, losses and other items required of the Partnership for federal and
state income tax purposes and shall use all reasonable efforts to furnish,
within ninety days of the close of each taxable year of the Partnership, the tax
information reasonably required by the Limited Partner for federal and state
income tax reporting purposes. The classification, realization and recognition
of income, gain, losses and deductions and other items shall be on the accrual
method of accounting for federal income tax purposes. The taxable year of the
Partnership shall be the calendar year.

         9.2 Tax Elections. Except as otherwise provided herein, the General
Partner shall in its sole discretion, determine whether to make any available
election pursuant to the Code; provided, however, that the General Partner shall
make the election under Section 754 of the Code in accordance with applicable
regulations thereunder. The General Partner shall have the right to seek to
revoke any such election (including, without limitation, the election under
Section 754 of the Code) upon the General Partner's determination in its sole
discretion that such revocation is in the best interests of the Limited Partner.

         9.3 Tax Controversies. Subject to the provisions hereof, the General
Partner is designated the Tax Matters Partner (as defined in Section 6231 of the
Code), and is authorized and required to represent the Partnership (at the
Partnership's expense) in connection with all examinations of the Partnership's
affairs by tax authorities, including, without limitation, resulting
administrative and judicial proceedings, and to expend Partnership funds for
professional services and costs associated therewith. The Limited Partner agrees
to cooperate with the General Partner and to do or refrain from doing any or all
things reasonably required by the General Partner to conduct such proceedings.

         9.4 Organizational Expenses. The Partnership shall elect to deduct
expenses, if any, incurred by it in organizing the Partnership ratably over a
sixty-month period as provided in Section 709 of the Code.

         9.5 Withholding. Notwithstanding any other provision of this Agreement,
the General Partner is authorized to take any action that it determines in its
sole discretion to be necessary or appropriate to cause the Partnership to
comply with any withholding requirements established under the Code or any other
federal, state or local law including, without limitation, pursuant to Sections
1441, 1442, 1445 and 1446 of


                                      -30-
<PAGE>


the Code. To the extent that the Partnership is required to withhold and pay
over to any taxing authority any amount resulting from the allocation or
distribution of income to any Partner (including, without limitation, by reason
of Section 1446 of the Code), the amount withheld shall be treated as a
distribution of cash pursuant to Section 5.3 in the amount of such withholding
from such Partner.

         9.6 Opinions of Counsel. Notwithstanding any other provision of this
Agreement, if the Partnership is taxable for federal income tax purposes as a
corporation or otherwise taxed for federal income tax purposes as an entity at
any time and, pursuant to the provisions of this Agreement, an Opinion of
Counsel could otherwise be required to the effect that an action will not cause
the Partnership to become so taxable as a corporation or other entity or to be
treated as an association taxable as a corporation, such requirement for an
Opinion of Counsel shall be deemed automatically waived.



                       ARTICLE X - TRANSFER OF INTERESTS

         10.1 Transfer.

         (a) The term "transfer," when used in this Article X with respect to a
Partnership Interest, shall be deemed to refer to an appropriate transaction by
which a Partner disposes of its Partnership Interest to another Person and
includes a sale, assignment, gift, pledge, encumbrance, hypothecation, mortgage,
exchange or any other disposition by law or otherwise.

         (b) No Partnership Interest shall be transferred, in whole or in part,
except in accordance with the terms and conditions set forth in this Article X.
Any transfer or purported transfer of a Partnership Interest not made in
accordance with this Article X shall be null and void.

         10.2 Transfer of General Partner's Partnership Interest.

         (a) Except as set forth in Section 10.2(b), the General Partner may not
transfer all or any part of its Partnership Interest.

         (b) Neither Section 10.2(a) nor any other provision of this Agreement
shall be construed to prevent (and the Limited Partner does hereby expressly
consent to) (i) the transfer by the General Partner of all or a portion of its
Partnership Interest to one or more Affiliates, which Partnership Interest to
the extent not transferred to a successor General Partner, shall be a Limited
Partner's Partnership Interest or (ii) the transfer by the General Partner of
all its Partnership Interest upon its merger, consolidation or other combination
into any other Person or the transfer by it of all or substantially all of its
assets to another Person if, in the case of a transfer described in either
clause (i) or (ii) of this sentence, the rights and duties of the General
Partner with respect to the Partnership Interest so transferred as a General
Partner's Partnership Interest (or the rights and duties of a Limited Partner
with respect to the Partnership Interest so transferred as a Limited Partner's
Partnership Interest) are assumed by the transferee and the transferee agrees to
be bound by the provisions of this Agreement and the Investor Partnership
Agreement; provided, that in either such case, such transferee furnishes to the
Partnership an Opinion of Counsel that such merger, consolidation, combination,
transfer or assumption will not result in a loss of limited liability of the
Limited Partner or cause the Partnership to be taxable as a corporation or
otherwise taxed as an entity for federal income tax purposes. In the case of a


                                      -31-
<PAGE>


transfer of a Partnership Interest pursuant to this Section 10.2(b) to a Person
proposed as a successor general partner of the Partnership, the transferee or
successor (as the case may be) shall be admitted to the Partnership as the
General Partner immediately prior to the transfer of the Partnership Interest,
and the business of the Partnership shall continue without dissolution.

         10.3 Transfer of the Limited Partner's Partnership Interest. If the
Limited Partner merges, consolidates or otherwise combines into any other Person
or transfers all or substantially all of its assets to another Person, such
Person may become a substituted Limited Partner pursuant to Article XI. Except
as set forth in the immediately preceding sentence, the Limited Partner may not
transfer all or any part of its Partnership Interest or withdraw from the
Partnership.



                       ARTICLE XI - ADMISSION OF PARTNERS

         11.1 Admission of Substituted Limited Partner. Any Person that is the
successor in interest to the Limited Partner as described in Section 10.3 shall
be admitted to the Partnership as a limited partner upon (a) furnishing to the
General Partner (i) acceptance in form satisfactory to the General Partner of
all of the terms and conditions of this Agreement and (ii) such other documents
or instruments as may be required to effect its admission as a limited partner
in the Partnership and (b) obtaining the consent of the General Partner, which
consent may be withheld or granted in the sole discretion of the General
Partner. Such Person shall be admitted to the Partnership as a Limited Partner
immediately prior to the transfer of the Partnership Interest, and the business
of the Partnership shall continue without dissolution.

         11.2 Admission of Successor or General Partner. A successor General
Partner approved pursuant to Section 12.1 or the transferee of or successor to
all of the General Partner's Partnership Interest Pursuant to Section 10.2 who

the Partnership as the General Partner, effective immediately prior to the
withdrawal or removal of the General Partner pursuant to Section 12.1 or the
transfer of the General Partner's Partnership Interest pursuant to Section 10.2;
provided, however, that no such successor shall be admitted to the Partnership
until the terms of Section 10.2 have been complied with. Any such successor

case, the admission shall be subject to the successor General Partner executing

conditions of this Agreement and such other documents or instruments as may be
required to effect the admission.

         (a) The General Partner shall be deemed to have withdrawn from the
Partnership upon the occurrence of any one of the following events (each such
event herein referred to as an "Event of Withdrawal");

                  (i) the General Partner voluntarily withdraws from the
         Partnership by giving written notice to the Limited Partner;

                  (ii) the General Partner transfers all of its rights as
         General Partner pursuant to Section 10.2;

                  (iii) the General Partner is removed pursuant to Section 12.2;

                  (iv) the general partner of the Investor Partnership withdraws
         from, or is removed as the general partner of, the Investor Partnership
         and a successor general partner is not appointed in accordance with the
         Investor Partnership Agreement;

                  (v) the General Partner (A) makes a general assignment for the
         benefit of creditors; (B) files a voluntary bankruptcy petition; (C)
         files a petition or answer seeking for itself a reorganization,
         arrangement, composition, readjustment, liquidation, dissolution or
         similar relief under any law; (D) files an answer or other pleading
         admitting or failing to contest the material allegations of a petition
         filed against the General Partner in a proceeding of the type described
         in clauses (A)-(C) of this sentence; or (E) seeks, consents to or
         acquiesces in the appointment of a trustee receiver or liquidator of
         the General Partner or of all or any substantial part of its
         properties;

                  (vi) a final and non-appealable judgment is entered by a court
         with appropriate jurisdiction ruling that the General Partner is
         bankrupt or insolvent, or a final and non-appealable order for relief
         is entered by a court with appropriate jurisdiction against the General
         Partner, in each case under any federal or state bankruptcy or
         insolvency laws as now or hereafter in effect; or

                  (vii) a certificate of dissolution or its equivalent is filed
         for the General Partner, or ninety days expire after the date of notice
         to the General Partner of revocation of its charter without a
         reinstatement of its charter, under the laws of its state of
         incorporation.

If an Event of Withdrawal specified in this Section 12.1(a)(v), (vi) or (vii)
occurs, the withdrawing General Partner shall give written notice to the Limited
Partner within thirty days after such occurrence. The Partners hereby agree that
only the Events of Withdrawal described in this Section 12.1 shall result in the
withdrawal of the General Partner from the Partnership.

         (b) Withdrawal of the General Partner from the Partnership upon the
occurrence of an Event of Withdrawal will not constitute a breach of this
Agreement under the following circumstances: (i) at any time that the General
Partner ceases to be a General Partner pursuant to Section 12.1(a) (ii) or is
removed pursuant to Section 12.2; or (ii) at any time that the General


                                      -33-
<PAGE>


Partner is removed as provided in Section 12.1(a) (iii). If the General Partner
gives a notice of withdrawal pursuant to Section 12.1(a) (i) or if the General
Partner is removed pursuant to Section 12.2 or withdraws pursuant to Section
12.1(a) (ii), the Limited Partner may, prior to the effective date of such
withdrawal, elect a successor General Partner. If, prior to the effective date
of the General Partner's withdrawal or removal, a successor is not selected by
the Limited Partner as provided herein or the Partnership does not receive an
Opinion of Counsel that such withdrawal (following the selection of the
successor General Partner) would not result in the loss of the limited liability
of the Limited Partner or cause the Partnership to be taxable as a corporation
or otherwise taxed as an entity for federal income tax purposes, the Partnership
shall be dissolved in accordance with Section 13.1. If a successor General
Partner is elected and the Opinion of Counsel is rendered as provided in the
immediately preceding sentence, such successor shall be admitted (subject to
Section 11.2) immediately prior to the effective time of the withdrawal or
removal of the Departing Partner and shall continue the business of the
Partnership without dissolution.

         12.2 Removal of the General Partner. The General Partner may be removed
if such removal is approved by the Limited Partner. Any such action by the
Limited Partner for removal of the General Partner must also provide for the
election and succession of a new General Partner. Such removal shall be
effective immediately following the admission of the successor General Partner
pursuant to Article XI. The right of the Limited Partner to remove the General
Partner shall not exist or be exercised unless the Partnership has received an
Opinion of Counsel that the removal of the General Partner and the selection of
a successor General Partner will not result in the loss of limited liability of
the Limited Partner or the taxation of the Partnership as a corporation or
otherwise result in the Partnership being taxed as an entity for federal income
tax purposes.

         12.3 Interest of Departing Partner and Successor General Partner. The
Partnership Interest of a Departing Partner departing as a result of withdrawal
or removal pursuant to Section 12.1 or 12.2 shall (unless it is otherwise
required to be converted into Units pursuant to Section 13.2(b) of the Investor
Partnership Agreement) be purchased by the successor to the Departing Partner
for cash in amount equal to the fair market value of the Departing Partner's
Partnership Interest, determined as of the effective date of its departure in
the manner specified in the Investor Partnership Agreement for the purchase of a
Departing Interest (as defined in the Investor Partnership Agreement). Such
purchase (or conversion into Units, as applicable) shall be a condition to the
admission to the Partnership of the successor as the General Partner.
Notwithstanding the foregoing, an assignment of all or any portion of a General
Partner's (or Departing General Partner's) Partnership Interest to the Investor
Limited Partnership as Limited Partner, or to any other Person (other than an
individual) the ownership interest of which is then transferred to the Investor
Limited Partnership, can be made in exchange for an increased interest in the
Investor Limited Partnership and in lieu of a cash purchase.

         12.4 Reimbursement of Departing Partner. The Departing Partner shall be
entitled to receive all reimbursements due such Departing Partner pursuant to
Section 6.4, including, without limitation, any employee-related liabilities
(including, without limitation, severance liabilities), incurred in connection
with the termination of any employees employed by the General Partner for the
benefit of the Partnership.

         12.5 Withdrawal of the Limited Partner. The Limited Partner shall not
have any right to withdraw from the Partnership without the prior consent of the
General Partner.



                   ARTICLE XIII - DISSOLUTION AND LIQUIDATION

         13.1 Dissolution. The Partnership shall not be dissolved by the
admission of a Substituted Limited Partner or by the admission of a successor
General Partner in accordance with the terms of this Agreement. Upon the removal
or withdrawal of the General Partner any successor General Partner shall
continue the business of the Partnership. The Partnership shall dissolve, and
its affairs should be wound up, upon:

         (a) the expiration of its term as provided in Section 1.5;

         (b) an Event of Withdrawal of the General Partner as provided in
Section 12.1(a), unless a successor is named as provided in Section 12.1(b) and
the continuation of the business of the Partnership is approved by the Limited
Partner;

         (c) an election to dissolve the Partnership by the General Partner that
is approved by the Limited Partner hereby;

         (d) entry of a decree of judicial dissolution of the Partnership
pursuant to the provisions of the Delaware Act;

         (e) the sale of all or substantially all of the assets and properties
of the Partnership; or

         (f) the dissolution of the Investor Partnership.

         13.2 Liquidation. Upon dissolution of the Partnership, the General
Partner, or in the event the General Partner has been dissolved or removed,
become bankrupt as set forth in Section 12.1 or withdrawn from the Partnership,
a liquidator or liquidating committee approved by the Limited Partner, shall be
the Liquidator. The Liquidator (if other than the General Partner) shall be
entitled to receive such compensation for its services as may be approved by the
Limited Partner. The Liquidator shall agree not to resign at any time without
fifteen days' prior written notice and (if other than the General Partner) may
be removed at any time, with or without cause by notice of removal approved by
the Limited Partner. Upon dissolution, removal or resignation of the Liquidator,
a successor and substitute Liquidator (who shall have and succeed to all rights,
powers and duties of the original Liquidator) shall within thirty days
thereafter be approved by the Limited Partner. The right to approve a successor
or substitute Liquidator in the manner provided herein shall be deemed to refer
also to any such successor or substitute Liquidator approved in the manner
herein provided. Except as expressly provided in this Article XIII, the
Liquidator approved in the manner Provided herein shall have and may exercise,
without further authorization or consent of any of the parties hereto, all of
the powers conferred upon the General Partner under the terms of this Agreement
(but subject to all of the applicable limitations, contractual and otherwise,
upon the exercise of such powers, other than the limitation on sale set forth in
Section 6.3(b)) to the extent necessary or desirable in the good faith judgment
of the Liquidator to carry out the duties and functions of the Liquidator
hereunder for and during


                                      -35-
<PAGE>


such period of time as shall be reasonably required in the good faith judgment
of the Liquidator to complete the winding up and liquidation of the Partnership
as provided for herein. The Liquidator shall liquidate the assets of the
Partnership, and apply and distribute the proceeds of such liquidation in the
following order of priority, unless otherwise required by mandatory provisions
of applicable law:

         (a) the payment to creditors of the Partnership, including, without
limitation, Partners who are creditors, in the order of priority provided by
law; and the creation of a reserve of cash or other assets of the Partnership
for contingent liabilities in an amount, if any, determined by the Liquidator to
be appropriate for such purposes; and

         (b) to all Partners in accordance with the positive balances in their
respective Capital Accounts after taking into account adjustments to such
Capital Accounts pursuant to Section 5.1(c).

         13.3 Distributions in Kind. Notwithstanding the provisions of Section
13.2, which require the liquidation of the assets of the Partnership, but
subject to the order of priorities set forth therein, if prior to or upon
dissolution of the Partnership the Liquidator determines that an immediate sale
of part or all of the Partnership's assets would be impractical or would cause
undue loss to the Partners, the Liquidator may, in its absolute discretion,
defer for a reasonable time the liquidation of any assets except those necessary
to satisfy liabilities of the Partnership (including, without limitation, those
to Partners as creditors) and/or distribute to the Partners, in lieu of cash, as
tenants in common and in accordance with the provisions of Section 13.2,
undivided interests in such Partnership assets as the Liquidator deems not
suitable for liquidation. Any such distributions in kind shall be made only if,
in the good faith judgment of the Liquidator, such distributions in kind are in
the best interest of the Limited Partner, and shall be subject to such
conditions relating to the disposition and management of such properties as the
Liquidator deems reasonable and equitable and to any agreement governing the
operation of such properties at such time. The Liquidator shall determine the
fair market value of any property distributed in kind using such reasonable
method of valuation as it may adopt.

         13.4 Cancellation of Certificate of Limited Partnership. Upon the
completion of the distribution of Partnership cash and property as provided in
Sections 13.2 and 13.3, the Partnership shall be terminated and the Certificate
of Limited Partnership and all qualifications of the Partnership as a foreign
limited partnership in jurisdictions other than the State of Delaware shall be
canceled and such other actions as may be necessary to terminate the Partnership
shall be taken.

         13.5 Reasonable Time for Winding Up. A reasonable time shall be allowed
for the orderly winding up of business and affairs of the Partnership and the
liquidation of its assets pursuant to Section 13.2 in order to minimize any
losses otherwise attendant upon such winding up, and the provisions of this
Agreement shall remain in effect between the Partners during the period of
liquidation.

         13.6 Return of Capital. The General Partner shall not be personally
liable for the return of the Capital Contributions of the Limited Partners, or
any portion thereof, it being expressly understood that any such return shall be
made solely from Partnership assets.


                                      -36-
<PAGE>


         13.7 No Capital Account Restoration. No Partner shall have any
obligation to restore any negative balance in its Capital Account upon
liquidation of the Partnership.

         13.8 Waiver of Partition. Each Partner hereby waives any right to
partition of the Partnership property.



                ARTICLE XIV - AMENDMENT OF PARTNERSHIP AGREEMENT

         14.1 Amendment to be Adopted Solely by General Partner. The Limited
Partner agrees that the General Partner (pursuant to its powers of attorney from

facilitate uniformity of tax consequences within such classes of Units) or
comply with any rule, regulation, guideline or requirement of any National
Securities Exchange on which the Units are or will be listed for trading,
compliance with any of which the General Partner determines in its sole
discretion to be in the best interests of the Partnership and the Limited
Partner or (iii) that is required to effect the intent of the provisions of this
Agreement or is otherwise contemplated by this Agreement;
