1.03  Business of the Partnership; Investment Objective and Policies.

      (a)   The Partnership is one of a series of Partnerships which have been
            organized under English law or the laws of Delaware, United States,
            or may in the future be organized under English law or under the
            laws of any other jurisdiction to invest in securities of issuers
            doing business primarily in Poland, as set forth in a Confidential
            Private Placement Memorandum dated March 21, 1994 as it has been and
            as it may be supplemented from time to time (the "Memorandum"), and
            which are being jointly managed pursuant to a Joint Management
            Agreement (the "Joint Management Agreement") of even date herewith
            by Pioneering Management (Jersey) Limited, as manager (the
            "Manager") (as so jointly managed, the Partnership and such other
            partnerships are hereafter collectively referred to as the "Fund",
            and the other partnerships comprising the Fund are hereinafter
            referred to as the "Other Fund Entities"). It is the intention of
            the Partners that the investment portfolio of the Partnership be
            identical (as a percentage of net asset value) with the investment
            portfolios of the Other Fund Entities. Notwithstanding the
            foregoing, the relationship created among the Partnership and the
            Other Fund Entities by the Joint Management Agreement is one of
            contract only, and not of a partnership or joint venture, and does
            not create an entity of any kind, and neither the Partnership nor
            any Other Fund Entity shall have the right to bind or act for the
            other in any way whatsoever. Further, notwithstanding that the
            Partnership and the Other Fund Entities are separate and distinct
            entities and that the rights and obligations of the Partners are
            governed by the terms of this Agreement and the Delaware Act, the
            Partners have agreed that certain matters relating to the investment
            decisions of the Manager pursuant to the Joint Management Agreement
            shall be subject to the approval of specified percentages of the
            Partners and the partners of the Other Fund Entities on an aggregate
            basis as specified in Article 4 hereof.

            Subject to the foregoing, the business of the Partnership (the
            "Investment Objective") shall principally be to buy, sell, hold and
            otherwise invest in and deal with unlisted equity and equity related
            securities primarily of non-state-owned


                                      -2-
<PAGE>   3

            companies whose principal operations, headquarters, assets, sources
            of revenue or profits are in the Republic of Poland or which, in the
            judgment of Pioneer Investment Poland, as advisor for the
            Partnership (the "Advisor"), may benefit significantly from their
            commercial activities in Poland, and to engage in any other
            activities incident to or related to any of the foregoing.

            The investment policies of the Partnership (the "Investment
            Policies") are as follows:

            (i)   The Partnership will invest only in equity and equity related
                  securities of issuers which are incorporated in or which have
                  their principal operations in Poland (which are not more than
                  49% directly or indirectly owned by a government), or those
                  issuers meeting the criteria set forth in paragraph (iii)
                  below, or Polish public sector enterprises which are
                  participating in the Polish Government's privatisation
                  program, including the Mass Privatisation Program, or
                  implementing a program to achieve private ownership and
                  control, or which will be privatised as a result of the
                  investment by the Partnership (collectively, "Polish
                  Issuers");

            (ii)  Investments will be used to acquire interests in portfolio
                  companies, to finance and implement restructuring programs or
                  to finance specific projects or investment programs for the
                  creation, modernization or working capital requirements of
                  portfolio companies;

            (iii) All portfolio companies must be based in Poland, or in another
                  member country of the European Bank for Reconstruction and
                  Development (the "EBRD") in which case the business objectives
                  (but not necessarily all business relations) of such companies
                  must be exclusively restricted to investments in Poland;

            (iv)  The Partnership will not invest in enterprises whose primary
                  business is (x) arms manufacturing or other military-related
                  activities, (y) manufacture of tobacco products or hard
                  spirits, or (z) operation of casinos or other gambling
                  facilities;


                                      -3-
<PAGE>   4

            (v)   The Partnership will not be involved in hostile bids;

            (vi)  Pending investment in portfolio companies or distribution of
                  proceeds to Partners, the Partnership may hold cash and
                  investment grade money market instruments denominated in
                  currencies free from internal or external mandatory conversion
                  requirements or in financial instruments of the EBRD or in
                  obligations backed by the full faith and credit of the United
                  States of America or of Poland; and

            (vii) the Partnership will invest only in enterprises whose legal
                  form of organization is designed to limit the liability of
                  investors to the amount of capital invested; however, each
                  Partner acknowledges that, under certain circumstances, the
                  Partnership could be liable for an amount greater than the
                  amount invested, because under Polish law, an investor in a
                  "limited liability company" is potentially liable for unpaid
                  taxes of the company in a proportion equal to such investor's
                  share in profits of the company.

      (b)   In addition to any consents which may be required pursuant to
            Section 4.02 hereof, the Partnership shall not, without the consent
            of (i) the EBRD so long as the EBRD owns any Interest in the
            Partnership or any Other Fund Entities (ii) DEG - Deutsche
            Investitions- und Entwicklungsgesellschaft mbH ("DEG") so long as
            DEG continues to own at least the lesser of (A) ten percent (10%) of
            the aggregate number of Interests in the Partnership and the Other
            Fund Entities or (B) 11.3 Interests, and (iii) Lyndhurst Associates,
            Carnegie Mellon University and Henry Gailliot (collectively, the
            "Pittsburgh Group") so long as the Pittsburgh Group continues to own
            at least 10.5 Interests (and the consent of the representative of
            the Pittsburgh Group (the "Pittsburgh Representative") on the
            Oversight Board (as defined in the Joint Management Agreement) shall
            constitute the consent of the Pittsburgh Group required hereby):

                  (w)   modify the Investment Objective, or any of the
                        Investment Policies or Investment Restrictions;


                                      -4-

                  (x)   make any investments other than in accordance with the
                        Environmental Procedures attached hereto as Exhibit A,
                        and no investments may be made in companies which are
                        engaged in activities listed on the Environmental
                        Exclusion List attached hereto as Exhibit B (provided
                        that in the event the EBRD no longer owns any Interest
                        in the Partnership or any Other Fund Entities, such
                        Environmental Procedures may be modified by a majority
                        of the members of the Oversight Board);

                  (y)   amend any of the Fund Documents (as defined below),
                        except amendments which, in the reasonable judgment of
                        the Manager, (A) are required by law, (B) are
                        administrative in nature, or (C) are required for tax
                        reasons; or

                  (z)   upon becoming aware of any material environmental issue
                        which arises in connection with any investment, fail to
                        notify the EBRD, DEG or the Pittsburgh Representative,
                        as the case may be, of such issue and provide such
                        person with such reasonable information as it may
                        request concerning any such issue.

      (c)   The Partnership will annually prepare and make available to each
            Limited Partner an environmental report on the implementation of the
            Environmental Procedures, which shall, in particular, provide
            information on the following:

            (i)   the integration of the Environmental Procedures into the
                  investment process;

            (ii)  the use of local environmental consultants in the
                  implementation of the Environmental Procedures;

            (iii) the on-going monitoring of the environmental aspects of
                  investments;

                  made to the Partnership concerning the environmental aspects
                  of particular investments, together with a description of how
                  these issues have been addressed; and

            (vi)  a report on problems or difficulties encountered in carrying
                  out the Environmental Procedures;

            provided, that the Partnership shall not be required to prepare or
            make available such report at any time that the EBRD does not own
            any Interest in the Partnership or any Other Fund Entities.

      (d)   The General Partner is not in default (nor has any event occurred

            default) in the performance of any obligation, agreement or
            condition contained in this Agreement, nor, to the best of its
            knowledge, is it in violation of any statute, regulation, law,
            order, writ, injunction, judgment or decree to which it is subject,

            contribute the remaining balance of the Subscribed Capital pursuant
            to the terms hereof.

            Subscribed Capital") equal to twenty-five percent (25%) of that
            Partner's Subscribed Capital to the capital of the Partnership;

            collected First Installment of Subscribed Capital, the collected
            Second Installment of Subscribed Capital and the collected Third
            Installment of Subscribed Capital of all Partners have been
            committed to investments in Polish Issuers, and (ii) 100% of any
            Total Drawndown Capital which had been returned to the Partnership
            following the disposition of an investment in Polish Issuers has
            been reinvested or committed to investments in Polish Issuers or
            distributed or otherwise paid to the Partners or their affiliates,
            each of the Partners shall contribute an additional amount (the
            "Fourth Installment of Subscribed Capital") equal to twenty-five per
            cent (25%) of that Partner's Subscribed Capital (being the balance
            of that Partner's Subscribed Capital) to the capital of the
            Partnership; provided, however, that no such Fourth Installment of
            Subscribed Capital shall be payable if the Fourth Installment Notice
            shall not have been delivered to the Limited Partners prior to the
            Commitment Termination Date. For purposes of this Section 2.01, the
            total amount, at any time, of Subscribed Capital actually
            contributed by a Partner to the Partnership shall be that Partner's
            "Drawndown Capital," and the aggregate Drawndown Capital of all of
            the Partners shall be the "Total Drawndown Capital" of the
            Partnership.

      (c)   If any Limited Partner fails to contribute the Second Installment of
            Subscribed Capital, the Third Installment of Subscribed Capital or
            the Fourth Installment of Subscribed Capital on or before the date
            when such amount is due and payable, such Limited Partner (a
            "Defaulting Partner") shall be deemed to be in default hereunder,
            and the General Partner shall have all rights and remedies, on
            behalf


                                      -10-
<PAGE>   11

            of the Partnership, available at law or in equity to collect such
            amount from the Defaulting Partner. In addition, the General Partner
            shall have the option, exercisable as hereinafter provided, (i) to
            initiate the bid process described in Section 2.01(d), or (ii) to
            terminate the obligation of the Defaulting Partner to make further
            installments of Subscribed Capital and to cancel such Defaulting
            Partner's Interests. Notwithstanding whether either such option is
            exercised, so long as a Defaulting Partner remains in default, it
            (x) shall have no right to receive any cash distributions, and all
            such distributions in respect of the Interests held by such
            Defaulting Partner may be applied against such unpaid obligations,
            (y) shall not be entitled to exercise any voting rights, and (z)
            shall not have the right to inspect the books of account specified
            in Section 5.01 hereof. For purposes hereof, any partial payment by
            a Limited Partner on account of its obligation to make the Second
            Installment of Subscribed Capital, Third Installment of Subscribed
            Capital or Fourth Installment of Subscribed Capital shall be
            allocated pro rata to all of the Interests owned by such Limited
            Partner. In the event the General Partner exercises the option set
            forth in clause (ii) above, the amount then contained in the
            Defaulting Partner's Capital Account shall be allocated among the
            Non-Defaulting Partners (defined below) in proportion to their
            respective number of Interests in the Partnership.

      (d)   The option granted in paragraph (c) (i) above may be exercised by
            the General Partner, by giving notice to that effect to the
            Defaulting Partner, at any time within one hundred and eighty (180)
            days after the due date for payment of the installment that the
            Defaulting Partner failed to pay. After the expiration of ten
            business days following the date on which the General Partner has
            given such notice, the Defaulting Partner may not cure his default
            without the consent of the General Partner. Following the expiration
            of such 10-day period, the General Partner shall use all reasonable
            efforts to notify each other Partner who is not in default hereunder
            (a "Non-Defaulting Partner") that they may, within 30 days after the
            date of the aforesaid notice to the Defaulting Partner, submit to
            the General Partner a written bid to purchase all or any portion of
            the Interests of the Defaulting Partner (but not less


                                      -11-
<PAGE>   12

            than one Interest unless the Defaulting Partner holds less than one
            Interest, in which case any bid shall be for not less than the
            entire amount of the portion of an Interest held by the Defaulting
            Partner). Within 10 business days after the expiration of such
            period for submitting bids, the General Partner shall determine the
            highest bids received from the Non-Defaulting Partners (the "LP
            Purchasers"); provided, that if no bids are submitted during such
            period or if no bid is submitted which provides for payment to the
            Defaulting Partner of an amount in excess of 75% of the Drawndown
            Capital actually paid to the Partnership by the Defaulting Partner
            with respect to the Interests of the Defaulting Partner, then the
            General Partner shall be entitled to purchase such Interests by
            paying to the Defaulting Partner an amount equal to 75% of the
            Drawndown Capital actually paid to the Partnership by the Defaulting
            Partner with respect to such Interests. The purchaser(s) of such
            Interests, whether the General Partner or one or more LP Purchasers,
            shall also undertake to make to the Partnership the additional
            capital contributions, if any, required to be made by the Defaulting
            Partner on account of such Interests (including the installment of
            Subscribed Capital that the Defaulting Partner failed to pay) to the
            extent that such additional amounts have not been paid by the
            Defaulting Partner. In the event one or more Non-Defaulting Partners
            submit identical bids which would have been sufficient to purchase
            Interests pursuant to the terms hereof but for the fact that
            multiple bids were received, each at the same offer price and for
            the same number of Interests, the Interests of the Defaulting
            Partner which would otherwise have been purchased by them shall be
            allocated among them in proportion to their respective number of
            Interests in the Partnership. In the event one or more
            Non-Defaulting Partners submit bids which would have been sufficient
            to purchase Interests pursuant to the terms hereof but for the fact
            that multiple bids were received, each for a different number of
            Interests but at the same per-Interest offer price, then, the
            Interests of the Defaulting Partner available for purchase hereunder
            shall be allocated among such bids so that the bid for the largest
            number of Interests is satisfied before any other such bid and the
            remaining bids are satisfied so that the larger bids are satisfied
            before the smaller bids.

      (e)   The closing of the acquisition of the Interests of the Defaulting
            Partner by the General Partner or the LP Purchasers, as the case may
            be, shall occur on the 15th day after the expiration of the 30-day
            period for submitting bids or on the first business day after such
            15th day. The closing shall occur at the offices of the Partnership
            or at such other place as shall be agreed upon by the General
            Partner or the LP Purchaser, as the case may be, and the Defaulting
            Partner. At such closing, the General Partner or the LP Purchaser,
            as the case may be, shall pay to the Defaulting Partner the purchase
            price for the Interests of the Defaulting Partner as described in
            paragraph (d) above, and the Defaulting Partner (or the General
            Partner acting as attorney-in-fact for the Defaulting Partner
            pursuant to the power of attorney granted by each Limited Partner in
            paragraph (f) below) shall execute and deliver such agreements,
            instruments and other documents as are necessary to transfer to the
            General Partner or the LP Purchaser, as the case may be, all of the
            Defaulting Partner's right, title and interest in and to the
            Defaulting Partner's Interests in the Partnership, free and clear of
            all liens, encumbrances and restrictions, other than liens,
            encumbrances and restrictions imposed under the terms of this
            Agreement. In the event the General Partner purchases the Interests
            of a Defaulting Partner, the General Partner shall assume the status
            of a Limited Partner in respect thereof in addition to its status as
            General Partner.

      (f)   Each Limited Partner, by its acquisition of Interests, constitutes
            and appoints the General Partner, and its duly authorized
            representatives acting alone, and any person or entity which becomes
            a substitute or additional General Partner of the Partnership, its
            agent and attorney-in-fact for the purpose of executing and
            delivering any and all agreements, instruments and other documents
            necessary to convey such Limited Partner's Interests in the
            Partnership to the Partnership pursuant to Section 2.01(c) above or
            to the purchaser thereof pursuant to Section 2.01(d), which power of
            attorney, being coupled with an interest, is irrevocable and shall
            survive the death, dissolution or incapacity of any Limited Partner.

      (g)   Notwithstanding anything in this Section 2.01 to the contrary, the
            obligations of the Defaulting Partner to the Partnership to make
            additional capital contributions shall not be extinguished by the
            existence of the option to purchase its Interest described in
            Section 2.01(d) above or by the exercise of such option, but only
            by, and to the extent of, the payments made in the Defaulting
            Partner's place by any purchaser or purchasers of such Interest, and
            the Partnership may proceed to collect any amount due from the
            Defaulting Partner as and when due, together with interest thereon
            from the date for payment stated herein at an annual rate equal to
            the three-month LIBOR rate plus 5%, but not exceeding the maximum
            rate permitted by law, and all costs and expenses of collection
            incurred by the Partnership (including reasonable fees and
            disbursements of counsel). The obligations of the Defaulting Partner
            to the Partnership to make additional capital contributions shall be
            extinguished by the exercise of the option described in Section
            2.01(c)(ii) above.

      (h)   The rights granted to the Partners in this Section 2.01 are in
            addition to, and not in lieu of, the rights held by the Partnership
            by virtue of the security interest referred to in Section 2.01(a).

      (i)   Until the first anniversary of the date of this Partnership
            Agreement, the General Partner is authorized to accept subscriptions
            for the sale of additional Interests and to admit, at any time or
            from time to time, such subscribers as additional Partners; provided
            that (i) the aggregate number of Interests in the Partnership and in
            the Other Fund Entities shall not exceed 200; (ii) each Interest
            (other than an Interest for which an investor has committed to
            subscribe prior to the date of this Agreement) shall be sold for a
            capital commitment equal to such amount as shall be determined by a
            majority of the Oversight Board (provided, however, that the minimum
            capital commitment shall not be less than $500,000 (except for
            Interests purchased by investors with agreements to pay either a
            reduced or no placement fee, in which cases the minimum capital
            commitment shall be $485,000 plus the placement fee, if any, to be
            paid)); provided, that the General Partner may accept subscriptions
            for fractional Interests as long as the minimum capital commitment


                                      -14-
<PAGE>   15

            of any subscriber is no less than $100,000; and (iii) in no event
            shall:

            (A)   offers or sales of Interests be made to persons in the United
                  States other than to accredited investors (as such term is
                  defined in Rule 501(a) of Regulation D, promulgated under the
                  Securities Act of 1933, as amended (the "Securities Act")), or
                  to persons elsewhere except where offers and sales are
                  permitted under such circumstances;

            (B)   more than 99 investors be beneficial owners of the Interests
                  at any time; or

            (C)   any Partner be permitted to acquire 10% or more of the issued
                  and outstanding Interests if the number of beneficial owners
                  of such Partner, when added to the number of beneficial owners
                  of the then-admitted Partners, would result in more than 99
                  persons being beneficial owners of the Interests at any time.

            For purposes of clauses (B) and (C) of this Section 2.01(i), the
            number of Partners and the number of beneficial owners shall be
            determined by reference to Section 3(c)(1) of the Investment Company
            Act of 1940, as amended (the "Investment Company Act"), or to any
            successor provisions, laws or announcements.

      (j)   Each additional Partner shall become a party to this Agreement by
            signing (or by authorizing his duly appointed attorney-in-fact to
            sign) such number of counterpart signature pages to this Agreement
            and such other instrument or instruments, and in such manner and at
            such time, as the General Partner shall determine. Upon admission to
            the Partnership, each additional Partner shall contribute such
            Partner's First Installment of Subscribed Capital (and any other
            Installment of Subscribed Capital as shall then have been required
            of the other Partners).

      (k)   The General Partner (or its affiliates) has advanced certain
            organizational and offering expenses amounting in value to $_______,
            which expenses shall be considered, pursuant to Section 4.02(a)(vii)
            below, to be a cash contribution in satisfaction of the General
            Partner's obligation to contribute such


                                      -15-
<PAGE>   16

            amount to the capital of the Partnership under this Agreement
            (provided that any such organizational and offering expenses which
            exceed the foregoing amount shall be payable in cash to the General
            Partner pursuant to Section 4.02(a)(vii) below). Upon the admission
            of additional Partners pursuant to Section 2.01(i) above, the
            General Partner shall contribute such additional amounts of cash so
            that, following the admission of such Partners, the Capital Account
            of the General Partner is equal to at least 1% of the Capital
            Accounts of all of the Partners.

      (l)   No interest shall accrue on any contributions to the capital of the
            Partnership, and no Partner shall have the right to withdraw or to
            be repaid any capital contributed by such Partner or to receive any
            other payment in respect of such Partner's Interest in the
            Partnership, except as otherwise specifically provided in this
            Agreement.

      (m)   Each Limited Partner hereby constitutes and appoints the General
            Partner, as such Limited Partner's agent and attorney-in-fact for
            the purpose of (i) executing, delivering and filing such agreements,
            certificates and other instruments as any of said attorneys-in-fact
            shall deem necessary or appropriate in order to offer and sell
            Interests in the Partnership and to admit subscribers therefor into
            the Partnership as Partners and (ii) preparing a Schedule A to this
            Agreement, and such amendments to such Schedule A as may be
            necessary or appropriate from time to time, to reflect the admission
            of the Partners to the Partnership and the agreed upon amounts of
            their respective capital contributions. Such Schedule A, or any
            amendments thereto as aforesaid, when prepared by any of said
            attorneys-in-fact, shall be deemed a part of this Agreement and
            incorporated herein by reference, as of the effective date of such
            Schedule A or amendment thereto, to the same extent as if attached
            hereto and incorporated herein by this reference on the date hereof.
            The General Partner shall provide each Partner with a copy of each
            amendment to Schedule A, but only if such Partner is a Partner
            immediately before and after the time of such amendment, and, upon
            request, shall provide to any Partner a copy of each instrument
            executed by the General Partner pursuant to clause (i) above. The
            power of attorney contained in this Section 2.01(m) is coupled with
            an


                                      -16-
<PAGE>   17

            interest and, therefore, is irrevocable. This power of attorney
            shall survive the death, dissolution or incapacity of any Partner.

2.02  Certain Definitions.

      For purposes of this Agreement, unless the context otherwise requires, the
      following terms shall have the following respective meanings:

      (a)   "Carrying Value" means, with respect to any asset, the asset's
            adjusted basis for federal income tax purposes, except as follows:

            (i)   The initial Carrying Value of any asset contributed to the
                  Partnership shall be such asset's gross fair market value at
                  the time of such contribution;

            (ii)  The Carrying Values of all Partnership assets shall be
                  adjusted to equal their respective gross fair market values
                  upon an adjustment to the Partners' Capital Accounts as
                  provided in Section 2.03(c) hereof; and

            (iii) If the Carrying Value of an asset has been determined pursuant
                  to clause (i) or (ii) of this subsection (a), such Carrying
                  Value shall thereafter be adjusted in the same manner as would
                  the asset's adjusted basis for federal income tax purposes
                  except that depreciation deductions shall be computed in
                  accordance with Section 2.02(b)(i) hereof.

      (b)   "Net Profits" and "Net Losses" mean the taxable income or loss, as
            the case may be, for a period (or from a transaction) as determined
            in accordance with Section 703(a) of the Internal Revenue Code of
            1986, as amended (the "Code"), computed with the following
            adjustments:

            (i)   Items of gain, loss, and deduction shall be computed based
                  upon the Carrying Values of the Partnership's assets rather
                  than upon the assets' adjusted bases for federal income tax
                  purposes, and, in particular, the amount of any deductions for
                  depreciation or amortization with respect to an asset for a
                  period shall equal such asset's Carrying Value multiplied by a


                                      -17-
<PAGE>   18

                  fraction the numerator of which shall be the amount of
                  depreciation or amortization with respect to such asset
                  allowable for federal income tax purposes for such period and
                  the denominator of which shall be such asset's adjusted basis;

            (ii)  Any tax-exempt income received by the Partnership shall be
                  included as an item of gross income;

            (iii) The amount of any adjustments to the Carrying Values of any
                  assets of the Partnership pursuant to Code Section 743 shall
                  not be taken into account; and

            (iv)  Any expenditure of the Partnership described in Code Section
                  705(a)(2)(B) (including any expenditures treated as being
                  described in Section 705(a)(2)(B) pursuant to Treasury
                  Regulations under Code Section 704(b)) shall be treated as a
                  deductible expense.

      (c)   "Excess Negative Balance" for a Partner means the excess, if any, of
            (i) the negative balance in a Partner's Capital Account after
            reducing such balance by the net adjustments, allocations and
            distributions described in Treasury Regulation Section
            1.704-1(b)(2)(ii)(d)(4), (5) and (6) which, as of the end of the
            Partnership's taxable year, are reasonably expected to be made to
            such Partner, over (ii) the sum of (A) the amount, if any, which the
            Partner is required to restore to the Partnership upon liquidation
            of such Partner's Interest in the Partnership (or which is so
            treated pursuant to Treasury Regulations Section
            1.704-1(b)(2)(ii)(c)), and (B) that portion of any indebtedness of
            the Partnership with respect to which the Partner bears the economic
            risk of loss that such indebtedness would not be repaid out of the
            Partnership's assets if all of the Partnership's assets were sold at
            their respective Carrying Values as of the end of the fiscal year or
            other period and the proceeds from the sales together with any
            amounts described in clause (A), above, were used to pay the
            Partnership's liabilities.

      (d)   "Fiscal Period" means each twelve-month period (or portion thereof,
            with respect to any partial year) ending on December 31 of any year
            of the Partnership's existence.

2.03  Capital Accounts.

      A separate account (a "Capital Account") shall be maintained for each
      Partner and adjusted in accordance with regulations under Code Section
      704. To the extent consistent with such regulations, the following
      adjustments to such accounts shall be made:

      (a)   There shall be credited to each Partner's Capital Account the amount
            of any cash actually contributed by such Partner (not including the
            placement fee, if any, paid by such Partner) to the capital of the
            Partnership, the fair market value of any property contributed by
            such Partner to the capital of the Partnership and such Partner's
            share of the Net Profits of the Partnership and of any items in the
            nature of income or gain separately allocated to the Partners; and
            there shall be charged against each Partner's Capital Account the
            amount of all cash distributions to such Partner, the fair market
            value (without regard to Code Section 7701(g)) of any property
            distributed to such Partner by the Partnership (net of any liability
            secured by such property that the Partner is considered to assume or
            take subject to or under Code Section 752) and such Partner's share
            of the Net Losses of the Partnership and of any items in the nature
            of losses or deductions separately allocated to the Partners.

      (b)   If the Partnership at any time distributes any of its assets in-kind
            to any Partner, the Capital Account of each Partner shall be
            adjusted to account for that Partner's allocable share (as
            determined under Sections 2.04, 2.05 and 2.06 below) of the Net
            Profits or Net Losses that would have been realized by the
            Partnership had it sold the assets that were distributed at their
            respective fair market values (taking Code Section 7701(g) into
            account) immediately prior to their distribution.

      (c)   If elected by the General Partner, upon (i) any increase in a
            Partner's interest in the Partnership resulting from any non de
            minimis contribution of cash or property by such Partner to the
            Partnership


                                      -19-
<PAGE>   20

            or (ii) any reduction in a Partner's interest in the Partnership
            resulting from any non de minimis distribution to such Partner in
            redemption of all or a portion of such Partner's interest in the
            Partnership, and (iii) whenever else allowed under applicable
            Treasury Regulations, the Capital Account balance of each Partner
            shall be adjusted to reflect the Partner's allocable share (as
            determined pursuant to Sections 2.04, 2.05 and 2.06 below) of the
            Net Profits or Net Losses that would be realized by the Partnership
            if it sold all of its property at its fair market value (taking Code
            Section 7701(g) into account) on the date of the adjustment.

      (d)   In the event any Interest in the Partnership is transferred in
            accordance with the terms of this Agreement, the transferee shall
            succeed to the Capital Account of the transferor to the extent it
            relates to the transferred Interest.

2.04  General Allocations of Net Profits and Net Losses.

      (a)   Except as provided in Section 2.05 below, for any Fiscal Period the
            Net Profits of the Partnership from any source, including the
            receipt of interest and dividends or from a sale or other
            disposition of all or any portion of the Partnership's property
            (including Net Profits deemed realized from distributions of
            property in kind and including positive adjustments to Capital
            Accounts resulting from an election pursuant to Section 2.03(c)
            hereof) or upon liquidation of the Partnership shall be allocated to
            and among the Partners in accordance with their respective number of
            Interests in the Partnership.

      (b)   Except as provided in Section 2.05 below, for any Fiscal Period the
            Net Losses of the Partnership from any source, including operations
            or from a sale or other disposition of all or any portion of the
            Partnership's property (including Net Losses deemed realized from
            distributions of property in kind and including negative adjustments
            to Capital Accounts specified in Section 2.03(c) hereof) or upon
            liquidation of the Partnership shall be allocated to and among the
            Partners in accordance with their respective number of Interests in
            the Partnership.

2.05  Overriding Allocations of Net Profits and Net Losses.

      Notwithstanding the provisions of Section 2.04 above, the following
      allocations of Net Profits and Net Losses and items thereof shall be made:

            (a)   If at the end of any Partnership taxable year a Partner's
                  Capital Account has an Excess Negative Balance, then items of
                  gross income (computed with the adjustments set forth in
                  clauses (i), (ii) and (iii) of Section 2.02(b) hereof for such
                  period (and, if necessary, subsequent periods) shall first be
                  allocated to such Partner in an amount equal to such Partner's
                  Excess Negative Balance.

            (b)   In no event shall Net Losses of the Partnership be allocated
                  to a Partner if such allocation would cause or increase an
                  Excess Negative Balance in such Partner's Capital Account and
                  such Net Losses shall be allocated among the other Partners in
                  accordance with Section 2.04 hereof (subject to the provisions
                  of this Section 2.05(b)).

            (c)   In the event that Net Profits, Net Losses or items thereof are
                  allocated to one or more Partners pursuant to subsections (a)
                  or (b) above, subsequent Net Profits and Losses will first be
                  allocated (subject to the provisions of subsections (a) and
                  (b)) to the Partners having a Capital Account balance equal to
                  what it would have been had the original allocation of Net
                  Profits, Net Losses or items thereof pursuant to subsections
                  (a) or (b) not occurred.

            (d)   Except as otherwise provided herein or as required by Code
                  Section 704, for tax purposes, all items of income, gain,
                  loss, deduction or credit shall be allocated to the Partners
                  in the same manner as are Net Profits and Net Losses;
                  provided, however, that if the Carrying Value of any property
                  of the Partnership differs from its adjusted basis for tax
                  purposes, then items of income, gain, loss, deduction or
                  credit related to such property for tax purposes shall be
                  allocated among the Partners so as to take account of the
                  variation between the adjusted basis of the property for tax
                  purposes and its Carrying


                                      -21-
<PAGE>   22

                  Value in the manner provided for under Code Section 704(c).

            (e)   Except as provided in subsection (a) above, the interest of
                  the General Partner in each item of Partnership income, gain,
                  loss, deduction, or credit will be equal to at least one
                  percent (1%) of each of those items at all times during the
                  existence of the Partnership.

            (f)   In the event that the Partnership incurs any nonrecourse
                  indebtedness or partner nonrecourse indebtedness, allocations
                  of deductions attributable to such indebtedness and
                  allocations of minimum gain shall be made in accordance with
                  the provisions of the applicable Treasury Regulations
                  promulgated under Code Section 704(b).

            (g)   Each Limited Partner shall be allocated the expense associated
                  with any placement fee (together with any expense
                  reimbursements) or other costs payable by the Partnership in
                  connection with the acquisition of Interests by such Limited
                  Partner.

2.06  Allocations Upon Transfer or Admission.

      In the event that a Partner acquires an Interest in the Partnership either
      by transfer from another Partner or by acquisition from the Partnership,
      all Net Profits and Net Losses of the Partnership arising prior to or in
      connection with such acquisition or transfer (including adjustments to
      Capital Accounts pursuant to Section 2.03(c) hereof) shall be allocated
      among the Partners without giving effect to such acquisition or transfer.
      All other Net Profits and Net Losses of the Partnership shall be allocated
      among the Partners after giving effect to such acquisition or transfer.

2.07  Special Allocations.

      The General Partner may amend the provisions of this Agreement relating to
      the allocations of Net Profits, Net Losses and items thereof among the
      Partners if the Partnership is advised at any time by the Partnership's
      certified public accountants or legal counsel that in their opinion it is
      likely that such allocations would not be respected for Federal income tax
      purposes, but only to the extent necessary to give such provisions a basis
      on which such allocations would likely be


                                      -22-
<PAGE>   23

      respected in accordance with the advice of such accountants or legal
      counsel, so that any such amendment will have the least possible effect on
      such provisions set forth in this Agreement. Such amendment may include
      retroactive revaluation of the Partnership's assets as of the date of this
      Agreement if necessary to have the allocations set forth in this Article
      II have substantial economic effect pursuant to Treasury Regulation
      Section 1.704-1(b)(2)(iv)(f) and (g). Any such amendment shall be
      deemed to be made in compliance with the fiduciary obligation of the
      General Partner to the Partnership and the Limited Partners, and no such
      amendment shall give rise to any claim or cause of action by any Limited
      Partner. A copy of any such amendment shall be provided promptly to the
      Limited Partners.

2.08  Guaranteed Payments.

      Notwithstanding anything to the contrary provided in this Agreement, in
      the event that any fees, interest or other amounts paid to any one or more
      of the Partners and deducted by the Partnership, are disallowed as
      deductions to the Partnership on its federal income tax return and are
      treated as Partnership distributions, then (i) the Net Profits of the
      Partnership shall be decreased and the Net Losses of the Partnership shall
      be increased, as the case may be, for the years in which such fees,
      interest or other amounts were paid, by the amount of such fees, interest
      or other amounts that are treated as Partnership distributions; (ii) there
      shall be allocated to such Partners prior to the allocations pursuant to
      this Agreement, an amount of gross income for the year in which such fees,
      interest or other amounts were paid equal to the amount of such fees,
      interest or other amounts that are treated as Partnership distributions;
      and (iii) the amounts of such fees, interest or other amounts shall be
      deemed to have been distributed by the Partnership to such Partners and
      shall be appropriately reflected in the Capital Accounts of such Partners.
      In such event, an amount of expense equal to that portion of any cash
      distribution that is recharacterized as a guaranteed payment shall be
      specially allocated to the Partner receiving such guaranteed payment.

                  Partnership;

            (2)   payments of interest, principal and premium under any
                  indebtedness of the Partnership;

            (3)   amounts set aside as reserves by the General Partner as
                  necessary to meet the current or anticipated future needs of
                  the Partnership (including follow-on investments);

            (4)   at the election of the General Partner, proceeds from the sale
                  of investments in Polish Issuers prior to the Commitment
                  Termination Date representing a return to the Partnership of

            (5)   prior to the fifth anniversary of the date hereof, amounts
                  representing Drawndown Capital which has not yet been invested
                  in Polish Issuers; and

3.02  Certain Payments to the Internal Revenue Service Treated as Distributions.

      (a)   For purposes of this Section 3.02, the General Partner may assume
            that any Limited Partner who fails to provide to the General Partner
            satisfactory evidence of its tax status for United States federal
            income tax purposes is a foreign person taxable as a corporation.

      (b)   Notwithstanding anything to the contrary herein, to the extent that
            the Partnership is required, or elects, pursuant to applicable law,
            either (i) to pay tax (including estimated tax) on a Limited
            Partner's allocable share of the Partnership's items of income or
            gain, whether or not distributed, or (ii) to withhold and pay over
            to the tax authorities any portion of a distribution otherwise
            distributable to a Limited Partner, the General Partner may pay over
            such tax or such withheld amount to the tax authorities, and such
            amount shall be treated as a distribution to such Limited Partner at
            the time it is paid to the tax authorities.

4.    MANAGEMENT

4.01  Authority of the General Partner.

      Except as otherwise expressly provided in this Agreement or by law, all
      decisions respecting any matter set forth herein or otherwise affecting or
      arising out of the conduct of the business of the Partnership shall be
      made by the General Partner. The General Partner shall have the exclusive
      right and full authority to manage, conduct and operate the Partnership
      business on the terms and conditions described herein. Notwithstanding the
      foregoing, the General Partner shall not take any actions on behalf of the
      Partnership, or cause the Partnership to take any actions (other than with
      respect to matters which are applicable to the Partnership and the
      Partners hereof because of laws, rules and regulations applicable to the
      Partnership and its Partners which are not so applicable to the Other Fund
      Entities or the partners thereof (including the Delaware Act and the Code,
      or any portions thereof)), unless the same actions shall have been duly
      authorized and taken by, or on behalf of, the Other Fund Entities and are
      reasonably necessary or advisable to carry out the purposes of the
      Partnership.

            Partner;

      (j)   To take any action of any nature whatsoever necessary to offer and

      losses of and distributions from the Partnership and such interests
      therein as may be held by affiliates of the General Partner by virtue of
      their being Limited Partners hereunder, neither the General Partner nor
      any of its affiliates shall receive any compensation for services rendered
      in connection with the management or operation of the Partnership or its
      business. For purposes of this Agreement, "affiliate" of any individual or
      entity means any individual or entity that, directly or indirectly through
      one or more intermediaries, controls, is controlled by or is under common
      control with such individual or entity. The term "control" means the
      possession, directly or indirectly, of the power to direct or cause the
      direction of the management and policies of an individual or entity,
      whether through the ownership of voting securities, by contract or
      otherwise.

4.06  Liability of the General Partner; Indemnification.

      (a)   Neither the General Partner, nor any of its affiliates (an
            "Indemnified Party") shall have any liability to the Partnership or
            to any Partner for any loss suffered by the Partnership which arises
            out of any action or inaction of any Indemnified Party if such
            Indemnified Party determined reasonably and in good faith that the
            action or inaction was in or not opposed to the best interests of
            the Partnership and the action or inaction did not constitute
            Negligence or intentional misconduct of the Indemnified Party. Each
            Indemnified Party shall be indemnified by the Partnership against
            any losses, judgments, liabilities, expenses and amounts paid in
            settlement of any claims sustained by them which arise out of any
            action or inaction of such Indemnified Party if such Indemnified
            Party determined reasonably and in good faith that such action or
            inaction was in or not opposed to the best interests of the
            Partnership and such action or inaction did not constitute
            Negligence or intentional misconduct of the Indemnified Party. The
            Partnership shall not indemnify any Indemnified


                                      -33-
<PAGE>   34

            Party in connection with a proceeding (or part thereof) initiated by
            such Indemnified Party unless the initiation thereof was approved by
            a majority of the Independent Board Members (as defined in the Joint
            Management Agreement). The indemnification rights provided in this
            Section 4.06 (i) shall not be deemed exclusive of any other rights
            to which an Indemnified Party may be entitled under any law,
            agreement or vote of the Partners of the Partnership and the
            partners of the Other Fund Entities, and (ii) shall inure to the
            benefit of the heirs, executors and administrators of such persons.
            For purposes of this Agreement, "Negligence" by any person or entity
            means the failure of such person, other than in the exercise of such
            person's good faith business judgment, to perform a manifest duty in
            disregard of the consequences of the action or omission constituting
            such failure, taking into account in determining whether such person
            has been Negligent, the facts available to such person at the time
            of such failure and the circumstances then existing.

      (b)   Except as provided in Section 4.08, the reimbursement and indemnity
            obligations of the Partnership under this Agreement shall:

            (i)   be paid from, and only to the extent of, Partnership assets,
                  and no Partner shall have any personal liability on account
                  thereof;

            (ii)  be in addition to any liability which the Partnership may
                  otherwise have;

            (iii) extend upon the same terms and conditions to the directors,
                  officers, employees and affiliates of each Indemnified Party;
                  and

            (iv)  be binding upon and inure to the benefit of any successors,
                  assigns, heirs and personal representatives of each
                  Indemnified Party.

      (c)   An Indemnified Party shall ensure that all reasonable steps are
            taken to avoid or mitigate any loss or liability which might give
            rise to an indemnification under this Section 4.06. An Indemnified
            Party shall exercise reasonable care in the selection, instruction,
            engagement, retention and supervision of agents. If an Indemnified
            Party becomes aware of a


                                      -34-
<PAGE>   35

            matter that may give rise to its ability to be indemnified under
            this Section 4.06 it shall use all reasonable efforts to give notice
            of such matter as soon as practicable thereafter to the Limited
            Partners.

4.07  Limitations on Limited Partners.

      (a)   None of the Limited Partners shall:

            (i)   be permitted to take part in the management or control of the
                  business or affairs of the Partnership;

            (ii)  have any voice in the management or operation of any
                  Partnership property; or

            (iii) have the authority or power in his or her capacity as a
                  Limited Partner to act as agent for or on behalf of the
                  Partnership or any other Partner, to do any act which would be
                  binding on the Partnership or any other Partner, or to incur
                  any expenditures on behalf of or with respect to the
                  Partnership.

      (b)   Each Limited Partner may himself or through his agent or through any
            one or more of the members of the Oversight Board inspect the
            accounts of the Partnership and examine into the state and prospects
            of the Partnership business and advise with the Partners thereon.

4.08  Liability of Limited Partners.

      So long as each Limited Partner complies with the provisions of Section
      4.07, the liability of such Limited Partner for the losses, debts and
      obligations of the Partnership shall be limited to such Limited Partner's
      respective capital contribution and the Limited Partner's share of any
      undistributed net profits; provided, however, that under applicable
      partnership, fraudulent conveyance, or similar laws, a Limited Partner may
      be liable to the Partnership to the extent of previous distributions made
      to such Limited Partner, with interest, in the event that the Partnership
      does not have sufficient assets to discharge its liabilities.

      (a)   Except in connection with the admission to the Partnership of a
            general partner which is an assignee of the Interest of a General
            Partner as provided in Section 6.02, or in connection with the
            removal of the Manager pursuant to the Joint Management Agreement,
            no General Partner shall voluntarily retire or withdraw from the
            Partnership.

      (b)   The owners of a majority of the aggregate number of Interests in the
            Partnership (a "Majority-in-Interest of the Partnership's Partners")
            may expel the General Partner from the Partnership in the event any
            of the following has occurred:

            (i)   any action by the General Partner has been determined by a
                  court of competent jurisdiction to constitute fraud against
                  the Partnership;

            (ii)  the General Partner or any affiliate of the General Partner
                  has been convicted of any felony (but only if such conviction
                  has had a material adverse effect on the reputation of the
                  Partnership);

            (iii) a court of competent jurisdiction has determined that the
                  General Partner has committed a material breach of its
                  fiduciary obligations to the Partnership;

            (iv)  a court of competent jurisdiction has determined that the
                  General Partner has recklessly or wilfully committed a
                  material breach of the provisions of this Agreement or has
                  been Negligent in carrying out or failing to carry out its
                  duties hereunder;

            provided that, in any of such cases, the judgment of the court of
            competent jurisdiction is a final judgment with no right of appeal
            and further provided that no such decision to expel the General
            Partner shall be effective until the appointment of one or more
            General Partners to replace the General Partner, such appointment to
            be made by a Majority-in-Interest of the Partnership's Partners
            (provided that any such successor General Partner shall be an

4.10  Withdrawal of a General Partner.

      After a General Partner's bankruptcy, death, expulsion, dissolution (other
      than the dissolution of a General Partner which itself is a general or
      limited partnership and which does not wind up its business following the
      dissolution, but instead reconstitutes itself and continues its business),
      adjudication of incompetence or withdrawal (other than a withdrawal
      resulting from an assignment of all of the General Partner's Interest in
      the Partnership pursuant to Section 6.02 below), such General Partner's
      Interest shall (a) immediately, if there is then another general partner,
      or (b) immediately upon the election of a new general partner in
      accordance with Section 7.01(b), if no other general partner then existed,
      become that of a Limited Partner (without the necessity of receiving the
      consent of any other Partner). In such event, such General Partner shall
      cease to have any right to participate in any manner in the management or
      control of the business of the Partnership, but such General Partner's
      interest in the Net Profits and Net Losses and distributions of the
      Partnership shall remain unchanged. Any Limited Partner may obtain from
      the Partnership a list of all the Limited Partners and their addresses
      and, as provided in Section 7.01(b) hereof, a meeting may be called for
      the purpose of appointing one or more General Partners pursuant hereto.

4.11  Meetings of the Limited Partners.

      (a)   Meetings of the Limited Partners for any purpose (including the
            designation of representatives to the Oversight Board pursuant to
            the Joint Management Agreement or the other matters set forth in
            Section 4.02 above) may be called by the General Partner at any time
            and shall be called by the General Partner (i) before June 30, 1996
            and thereafter before June 30 in each calendar year; and (ii) within
            ten days after written request for such a meeting signed by (A) a
            majority of the Oversight Board constituted in the Joint Management
            Agreement or (B) 10% in interest of the Partnership's Limited
            Partners (as defined below); provided, that no more than one meeting
            may be called by Limited Partners during any twelve-month period,
            except that meetings called to appoint a new General Partner
            pursuant to Section 4.09 or 4.10 hereof shall not be subject to this
            limitation and, notwithstanding the foregoing, meetings may be
            called at any time by that number of Limited Partners who own more
            than 50% of the aggregate number of Interests in the Partnership.
            Any such request shall


                                      -37-
<PAGE>   38

            state the purpose of the proposed meeting and the matters proposed
            to be acted upon thereat. Meetings shall be held at the principal
            office of the General Partner or at such other place outside the
            United States as may be designated by the General Partner, or, if
            the meeting is called upon the request of the Oversight Board or
            Limited Partners, such place outside the United States and at such
            time as is designated by the Oversight Board or such Limited
            Partners. At each meeting, the Limited Partners shall be given the
            opportunity to review and discuss the Partnership's investment
            activities with the General Partner and a representative of the
            Manager and the Advisor. In addition, the General Partner may, and
            upon receipt of a written request signed by that number of Limited
            Partners who own more than 10% of the aggregate number of Interests
            in the Partnership (such number of Limited Partners being referred
            to as "10% in interest of the Partnership's Limited Partners"), the
            General Partner shall, submit any matter upon which the Limited
            Partners are entitled to act to the Limited Partners for a vote by
            written consent without a meeting (in which case the vote shall only
            be passed if approved by such number of Partners as would have been
            required had such vote been taken at a meeting).

      (b)   Notice of any meeting to be held pursuant to paragraph (a) above or
            Section 4.10 hereof shall be given not less than 10 days nor more
            than 60 days before the date of the meeting, to each Limited Partner
            at his record address on the books of the Partnership, or at such
            other address which he may have furnished in writing to the General
            Partner of the Partnership. Such notice shall be in writing, and
            shall state the place, date and hour of the meeting and shall
            indicate (if so) that the notice is being issued at or by the
            direction of the Limited Partner or Limited Partners calling the
            meeting. If a meeting is adjourned to another time or place, and if
            an announcement of the adjournment or time or place is made at the
            meeting, it shall not be necessary to give notice of the adjourned
            meeting.

      (c)   For the purpose of determining the Partners entitled to vote at any
            meeting of the Partners, or any adjournment thereof, or to vote by
            written consent without a meeting, the General Partner (or, in the
            case of votes to be taken at meetings called pursuant to Section
            4.10 hereof, the Limited Partner or Partners calling the meeting)
            may fix, in advance, a date as the record date


                                      -38-
<PAGE>   39


          for any such determination of Partners. Such date shall not be more
          than 50 days nor less than ten days before any such meeting or
          submission of a matter to the Partners for a vote by written consent.

     (d)  Each Partner may authorize any person or persons to act for him by
          proxy with respect to any matter in which such Partner is entitled to
          participate, whether by waiving notice of any meeting, or voting or
          participating at a meeting. Every proxy must be signed by the Partner
          or his attorney-in-fact. No proxy shall be valid after the expiration
          of 12 months from the date thereof unless otherwise provided in the
          proxy. Every proxy shall be revocable at the pleasure of the Partner
          executing it.

     (e)  At each meeting of Partners, the Partners present or represented by
          proxy shall elect such officers and adopt such rules for the conduct
          of such meeting as they shall deem appropriate. For purposes of
          determining whether a matter has been approved by a
          Majority-in-Interest of the Fund's Partners or the applicable
          Super-Majority-in-Interest of the Fund's Partners, the vote on such
          matter taken by the partners of any or all of the Other Fund Entities
          may, but need not be, taken simultaneously and at the same meeting as
          the vote on such matter taken by the Partners, and the votes of
          partners of the Other Fund Entities shall be aggregated with the votes
          of the Partners to determine whether a matter has been approved by a
          Majority-In-Interest of the Fund's Partners or the applicable
          Super-Majority-In-Interest of the Fund's Partners so long as such
          votes are taken not more than 30 days apart.

6.    ASSIGNABILITY OF INTERESTS

6.01  Substitution and Assignment of a Limited Partner's Interests.

      (a)   A Limited Partner may not sell, transfer, assign, pledge or
            otherwise dispose of (collectively, "transfer") all or any part of
            such Limited Partner's Interests (whether voluntarily, involuntarily
            or by operation of law), except in accordance with the following to
            the reasonable satisfaction of the General Partner:

            (i)   no such transfer shall be made unless, in the opinion of
                  counsel to the Partnership, (x) such transfer would not
                  require registration under the Securities Act, or otherwise
                  result in the violation of any other applicable securities
                  law, (y) such transfer would not require registration


                                      -42-
<PAGE>   43

                  under the Investment Company Act, and (z) such transfer would
                  not result in adverse tax consequences to the Partnership or
                  the Partners thereof (including the Partnership being treated
                  as an association taxable as a corporation);

            (ii)  the transferee shall have paid to the Partnership all costs
                  and expenses incurred by the Partnership in connection with
                  such transfer;

            (iii) the Partnership shall not be required to recognize any such
                  transfer until the instrument conveying such Interest has been
                  delivered to the General Partner for recordation on the books
                  of the Partnership; and

            (iv)  unless a transferee becomes a substituted limited partner in
                  accordance with the provisions set forth below, such
                  transferee shall not be entitled to any of the rights granted
                  to a Limited Partner hereunder, other than the right (unless
                  prohibited by Section 6.01(a)(i) hereof) to receive all or
                  part of the share of the net profits, net losses,
                  distributions or returns of capital to which the transferor
                  would otherwise be entitled.

      (b)   A transferee of the Interest of a Limited Partner, or any portion
            thereof, shall become a substituted limited partner having the
            rights and powers of, and become subject to the restrictions and
            liabilities of, a Limited Partner, as the case may be, if, and only
            if:

            (i)   the transferor gives the transferee such right;

            (ii)  the transferee pays to the Partnership all costs and expenses
                  incurred in connection with such substitution, including
                  specifically, without limitation, costs incurred in amending
                  the Partnership's then current Certificate of Limited
                  Partnership, if necessary; and

            (iii) the transferee executes and delivers such instruments, in form
                  and substance satisfactory to the General Partner, as the
                  General Partner may deem necessary or desirable to effect such
                  substitution and to confirm the agreement of the transferee to
                  be bound by all of the terms and provisions of this Agreement.


                                      -43-
<PAGE>   44

      (c)   Notwithstanding anything to the contrary contained herein, the
            General Partner may impose such additional restrictions on the
            transfer of Partnership Interests as may be reasonably required, in
            the opinion of counsel to the Partnership, to prevent the taxation
            of the Partnership for federal income tax purposes as a corporation
            or as an association taxable as a corporation, including without
            limitation, preventing Partnership Interests from being traded on an
            established securities market or readily tradeable on a secondary
            market (or the substantial equivalent thereof), and making any
            amendment to this Agreement as the General Partner in its reasonable
            discretion may determine to be necessary or appropriate in order to
            impose such restrictions.

      (d)   The Partnership and the General Partner shall be entitled to treat
            the record owner of any Interest as the absolute owner thereof in
            all respects, and shall incur no liability for distributions of cash
            or other property made in good faith to such owner until such time
            as a written instrument conveying such Interest has been received
            and accepted by the General Partner and recorded on the books of the
            Partnership and the other conditions for transfer set forth herein
            have been satisfied. The General Partner may refuse to accept a
            transfer until the end of the next successive quarterly accounting
            period. In no event shall any Interest, or any portion thereof, be
            transferred to a minor or incompetent, and any such attempted
            transfer shall be void and ineffectual and shall not bind the
            Partnership or the General Partner.

      (e)   The death or incompetency of a Limited Partner shall not dissolve
            the Partnership. A transferee of an Interest, whether or not it
            becomes a substitute limited partner, which desires to make a
            further transfer of such Interest shall be subject to all of the
            provisions of this Section 6.01 to the same extent and in the same
            manner as a Limited Partner desiring to make a transfer of its
            Interest.

6.02  Assignment of a General Partner's Interest.

      The Interest of a General Partner in the Partnership shall be assignable,
      in whole or in part, at any time and from time to time, to any person or
      entity so long as such transfer will not, in the opinion of the lawyer to
      the Partnership, result in any adverse consequences to the Partnership,
      including


                                      -44-
<PAGE>   45

      without limitation the withdrawal of Jersey regulatory supervision or the
      Partnership's listing on the securities exchange, if any, on which it is
      then listed; provided, that in no event shall an assignee of all or a
      portion of a General Partner's Interest in the Partnership become a
      General Partner or have the authority to participate in the management of
      the Partnership or to incur any obligations on behalf of the Partnership,
      unless:

            (a)   the assigning General Partner gives the assignee such right;

            (b)   the assignee pays to the Partnership all costs and expenses
                  incurred in connection with such assignment, including
                  specifically, without limitation, costs incurred in amending
                  the Partnership's Certificate of Limited Partnership;

            (c)   the assignee executes and delivers such instruments, in form
                  and substance satisfactory to the General Partner, as the
                  General Partner may deem necessary or desirable to effect the
                  admission of the assignee into the Partnership and to confirm
                  the agreement of the assignee to be bound by all of the terms
                  and provisions of this Agreement;

            (d)   The Partnership receives an opinion of counsel to the
                  Partnership that the Partnership will continue to be
                  classified as a partnership for federal income tax purposes
                  notwithstanding the admission of the new general partner and,
                  if applicable, the withdrawal of the assignor General Partner;
                  and

            (e)   except for assignments to an affiliate of the General Partner,

                  business), adjudication of incompetence or any other event of
                  withdrawal (as defined in the Delaware Act), unless there is

                  business of the Partnership);

            percentage in interest of the Partners as may be required by the
            Delaware Act) of the Partnership's Partners (which for this purpose
            shall include (A) the EBRD so long as the EBRD owns any Interest in

            former General Partner which will become a Limited Partner by
            operation of Section 4.09 if a new General Partner is appointed),
            elect to continue the Partnership and the Partnership business and
            consent to the appointment, effective as of the date of the event
            specified in Section 7.01(a)(ii) hereof, of one or more additional
            general partners of the Partnership, if necessary or desired.

      (c)   Dissolution of the Partnership shall be effective on the day on
            which the event occurs giving rise to the dissolution, but the
            Partnership shall not terminate until the Partnership's Certificate
            of Limited Partnership shall have been cancelled and the assets of
            the Partnership shall have been distributed as provided herein.
            Notwithstanding the dissolution of the Partnership, prior to the
            termination of the Partnership, as aforesaid, the business of the
            Partnership and the affairs of the Partners, as such, shall continue
            to be governed by this Agreement. Upon dissolution, the General
            Partner or a liquidator appointed by a Majority-in-Interest of the
            Partnership's Partners, shall liquidate and distribute the assets of
            the Partnership, apply and distribute the proceeds of any sale
            thereof as contemplated by this Agreement and cause the cancellation
            of the Partnership's Certificate of Limited Partnership.

7.02  Distributions Upon Liquidation.

      (a)   After payment of liabilities owing to creditors, the General Partner
            or liquidator shall set up such reserves as it deems reasonably
            necessary for any contingent or unforeseen liabilities or
            obligations of the Partnership, including the expenses of
            liquidation. Such reserves may be paid over by the General Partner
            or liquidator to a bank, to be held in escrow for the purpose of
            paying any such contingent or unforeseen


                                      -47-
<PAGE>   48

            liabilities or obligations and, at the expiration of such period as
            the General Partner or liquidator may deem advisable, such reserves
            shall be distributed to the Partners or their assigns in the manner
            set forth below in Section 7.02(b). After paying such liabilities
            and providing for such reserves, the General Partner or liquidator
            shall cause the remaining net assets of the Partnership to be
            distributed to and among the Partners in the manner set forth below
            in Section 7.02(b). In the event that any part of such net assets
            consists of securities or other non-cash assets, the General Partner
            or liquidator shall, unless a distribution of such assets is
            approved as set forth in Section 4.02(c)(ii) above, take such steps
            as it deems appropriate to convert such assets into cash.

      (b)   After payment or provision for all liabilities of the Partnership
            pursuant to Section 7.02(a), and the allocation of Net Profits and
            Net Losses pursuant to Sections 2.03 through 2.06 (including any
            deemed Net Profits or Net Losses attributable to assets to be
            distributed to the Partners in-kind in accordance with Section
            2.03(b) or otherwise pursuant to Sections 2.04 and 2.05), the
            General Partner shall distribute the remaining Partnership assets to
            the Partners in accordance with their respective positive Capital
            Account balances. For the purposes of this Section 7.02 (subject to
            paragraph (a) above), an asset distributed to a Partner in kind
            shall be considered as a distribution in the amount of the asset's
            fair market value (net of liabilities secured by such asset that the
            Partner is considered to assume or take subject to or under Code
            Section 752).

      (c)   The General Partner shall be obligated to make the following
            contributions to the capital of the Partnership in addition to the
            contributions referred to under Section 2.01(k) hereof:

            (i)   Upon dissolution of the Partnership, after any allocation of
                  Net Profits or Net Losses pursuant to Sections 2.04 and 2.05
                  hereof and the initial distributions to the Partners pursuant
                  to Section 7.02(b) hereof, the General Partner shall
                  contribute to the capital of the Partnership an amount equal
                  to the lesser of (x) its negative Capital Account balance, if
                  any, and (y) the excess of (A) 1.01% of the total capital
                  contributions of the Limited Partners over (B) the aggregate
                  amount


                                      -48-
<PAGE>   49

                  of capital previously contributed to the Partnership by the
                  General Partner. Such amount shall be treated as additional
                  liquidation proceeds subject to Section 7.02 hereof.

            (ii)  In addition, upon the liquidation of the Interest of a General
                  Partner other than pursuant to a dissolution of the
                  Partnership, the General Partner whose Interest is liquidated
                  shall contribute to the Partnership the amount such General
                  Partner would have been obligated to contribute pursuant to
                  clause (i) above, had the Partnership dissolved at the time of
                  the liquidation of the General Partner's Interest.

      In addition to any amendments otherwise authorized herein, amendments may
      be made to this Agreement from time to time in any of the following
      manners:

      (a)   By a writing executed by a Majority-in-Interest of the Partners;
            provided, however, that (i) any amendment which would increase the
            liability of a Limited Partner to the Partnership, amend Section
            2.01, 2.03, 2.04 (except as provided in clause (b) below), 2.05,
            3.01, 6.01, 7.01, 7.02 or this Section 8.04(a) may be made only by a
            writing executed by all of the Partners affected thereby; (ii)
            Section 4.02(c) may only be


                                      -50-
<PAGE>   51

            amended with the consent of the applicable
            Super-Majority-in-Interest of the Fund's Partners; (iii) Sections
            1.03(b) and 4.12 may only be amended with the consent of the EBRD
            (if the EBRD then has special approval rights pursuant thereto);
            (iv) Sections 1.03(b) and 4.13 may only be amended with the consent
            of DEG (if DEG then has special approval rights pursuant thereto);
            (v) Sections 1.03(b) and 4.14 may only be amended with the consent
            of the Pittsburgh Representative (if the Pittsburgh Representative
            then has special approval rights pursuant thereto); and (vi) no
            amendment may be made to this Agreement (other than amendments with
            respect to matters which are applicable to the Partnership and the
            Partners hereof because of laws, rules and regulations applicable to
            the Partnership and its Partners which are not so applicable to the
            Other Fund Entities or the partners thereof (including the Delaware
            Act and the Code, or any portions thereof) (any such amendment being
            hereinafter referred to as a "U.S. - Specific Amendment")) unless a
            similar amendment has been made to the partnership agreements of the
            Other Fund Entities. Further, the Partners agree to amend this
            Agreement as directed by a Majority-in-Interest of the Fund's
            Partners; provided, that similar amendments have been made to the
            partnership agreements of the Other Fund Entities and that the
            required amendment does not contravene Delaware law.

      (b)   By the General Partner, without the consent or approval of the
            Limited Partners, to amend appropriate provisions of this Agreement
            if the Partnership is advised at any time by its legal counsel that
            the allocations of Net Profits and Losses provided in Section 2.04
            hereof are unlikely to be respected for federal income tax purposes,
            either because of the promulgation and adoption of Treasury
            regulations under Code Section 704 or other developments in
            applicable law. In making any such amendment, the General Partner
            shall use its best efforts to effect as little change in the
            economic and tax arrangements among the Partners as it shall
            determine in its sole discretion to be necessary to provide for
            allocations of profits and losses to the Limited Partners which it
            believes will be respected for federal income tax purposes. Any
            amendments made by the General Partner pursuant to this subsection
            8.04(b) shall be deemed to be made pursuant to the fiduciary
            obligations of the General Partner to the Partnership and to the
            Limited Partners, and no such amendment shall


                                      -51-
<PAGE>   52

            give rise to any claim or cause of action by any Limited Partner.

8.05  No Waiver.

      The failure of any Partner to insist upon strict performance of a covenant
      hereunder or of any obligation hereunder, irrespective of the length of
      time for which such failure continues, shall not be a waiver of such
      Partner's right to demand strict compliance in the future. No consent or
      waiver, express or implied, to or of any breach or default in the
      performance of any obligation hereunder, shall constitute a consent or
      waiver to or of any other breach or default in the performance of the same
      or any other obligation hereunder.

8.06  Creditors.

      None of the provisions of this Agreement shall be for the benefit of or
      enforceable by any creditor of any Partner or of the Partnership other
      than a Partner who is a creditor of the Partnership pursuant to the terms
      of this Agreement.

8.07  Entire Agreement.

      This Agreement constitutes the full and complete agreement of the parties
      hereto with respect to the subject matter hereof and supersedes any prior
      written or oral agreements among the parties with respect to such subject
      matter.

8.08  Captions.

      Titles or captions of Articles or Sections contained in this Agreement are
      inserted only as a matter of convenience and for reference, and in no way
      define, limit, extend or describe the scope of this Agreement or the
      intent of any provision hereof.

8.09  Counterparts.

      This Agreement may be executed in a number of counterparts, all of which
      together shall for all purposes constitute one Agreement, binding on all
      the Partners, notwithstanding that all Partners have not signed the same
      counterpart.

      The invalidity or unenforceability of any provision of this Agreement
      shall not affect the validity or enforceability of any other provision.

8.11  Applicable Law.

      This Agreement and the rights and obligations of the parties hereunder
      shall be governed by, and interpreted, construed and enforced in
      accordance with, the laws of the State of Delaware.

8.12  Arbitration.

      (a)   Any dispute, controversy or claim arising out of or relating to this
            Agreement, or the breach, termination or invalidity thereof, shall
            be referred to and finally resolved by arbitration administered by
            the London Court of International Arbitration in accordance with the
            UNCITRAL Arbitration Rules as in force and effect on the date of
            this Agreement. Any dispute shall be submitted to an arbitral
            tribunal of one arbitrator appointed by the London Court of
            International Arbitration which shall, regardless of the number of
            parties to such dispute, be empowered to act as the appointing
            authority for such purposes. The place of arbitration shall be
            London, England, and the English language shall be used throughout
            the arbitral proceedings. Without prejudice to the rights of the
            EBRD set out in paragraph (c) of this Section, the General Partner
            and the Limited Partners agree that the jurisdiction of any court or
            other judicial authority to rule on a question of law affecting the
            arbitration or to hear any appeal from or entertain any judicial
            review of the arbitral award is hereby ousted. The General Partner
            and the Limited Partners agree that any award of the arbitrator may
            be enforced in the courts of England.

      (b)   The arbitral tribunal shall have authority to consider and include
            in any proceeding, decision or award, any dispute properly brought
            before it by any party to this Agreement insofar as such dispute
            arises out of this Agreement, but subject to the foregoing no other
            parties or other disputes shall be included in, or consolidated
            with, the arbitral proceedings.

      (c)   Nothing in this Section shall be construed as a waiver, renunciation
            or other modification of the privileges, immunities and exemptions
            of the EBRD accorded under the Agreement Establishing the European
            Bank for Reconstruction and Development dated May 29, 1990,
            international convention or any applicable laws.

8.13  Partition.

      to have the property of the Partnership partitioned, or to file a
      complaint or institute any proceeding at law or in equity to have the
      property of the Partnership partitioned, and each Partner, on such
      Partner's own behalf, and on behalf of such Partner's successors,
      representatives, heirs, and assigns, hereby waives any such right. It is
      the intention of the Partners that during the term of this Agreement, the
      rights of the Partners and their successors-in-interest, as among
      themselves, shall be governed by the terms of this Agreement, and that the
      right of any Partner or successor-in-interest to assign, transfer, sell or
      otherwise dispose of such Partner's interest in the property of the
      Partnership shall be subject to the limitations and restrictions of this
      Agreement.

                            PIONEER POLAND U.S., L.P.

                                  AMENDMENT TO
                              AMENDED AND RESTATED
                          LIMITED PARTNERSHIP AGREEMENT

      THE AMENDED AND RESTATED LIMITED PARTNERSHIP AGREEMENT, dated as of
December 14, 1994 (as amended to date, the "Agreement") of Pioneer Poland U.S.,
L.P., a Delaware limited partnership (the "Partnership"), is hereby amended
effective as of the 3rd day of August, 1999. Capitalized terms used herein, and
not otherwise defined herein, shall have the respective meanings ascribed to
them in the Agreement.

      WHEREAS, on the date hereof, Pioneer Poland U.S. (Jersey) Limited (the
"Old General Partner") is the sole general partner of the Partnership; and

      WHEREAS, the Old General Partner desires to cease to serve as a general
partner of the Partnership, but desires to retain its economic interest in the
Partnership as a limited partnership interest; and

      WHEREAS, the Old General Partner will retain all of its obligations under
the Agreement to contribute capital to the Partnership at the times and on the
terms specified in the Agreement, including without limitation, Section 2.01(a)
and (k) of the Agreement; and

      WHEREAS, Pioneer Poland GP Limited Partnership, a Delaware Limited
Partnership (the new General Partner"), desires to be admitted to the
Partnership as a general partner, and to assume the obligations and
responsibilities of the General Partner under the Agreement (other than the
obligations of the Old General Partner to contribute capital to the Partnership,
which will be retained by the Old General Partner); and

      WHEREAS, on the date hereof, the Partnership and the Manager have modified
the terms of the Joint Management Agreement to eliminate the Partnership's
obligation to pay Incentive Management Fees thereunder, in consideration for,
among other things, the agreement of the Partners in the Partnership to grant a
partnership interest to the New General Partner which is generally economically
equivalent to the Incentive Management Fee; and

      WHEREAS, on or before the date hereof, all persons currently owning
limited partnership interests in the Partnership and general partnership
interests in the Partnership have approved the foregoing matters.
<PAGE>   84

      NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:

      1. Assignment and Assumption of Interest Currently Held by Old General
Partner. Effective as of the date hereof, the Old General Partner shall cease to
serve as a general partner of the Partnership. The Old General Partner shall
retain its economic interest in the Partnership as a Limited Partner, with all
of the rights and obligations of a Limited Partner, and its right to
indemnification under Section 4.06 of the Agreement in respect of all periods of
time during which it served as a General Partner. The Old General Partner agrees
to be bound by and subject to the terms of the Agreement as a Limited Partner.
Without limiting the foregoing, the Old General Partner shall retain, and
continue to be responsible for, all of its obligations contribute capital to the
Partnership, in the amounts, on the terms and at the times specified in the
Agreement.

      By its execution of this Amendment, the Old General Partner hereby agrees
to be bound by each and every provision of the Agreement which is applicable to
a Limited Partner, including without limitation, the powers of attorney set
forth in Sections 2.01(f) and 8.03 of the Agreement. The Old General Partner
hereby agrees that its limited partnership interest in the Partnership is
subject to restrictions on transfer contained in the Partnership Agreement, and
under applicable state and federal securities laws relating to unregistered
securities, and the Old General Partner agrees to abide by such restrictions.

      From and after the date hereof, the Old General Partner shall have no
further responsibility for performing any of the obligations or duties of the
General Partner under the Agreement (except for the capital contribution
obligations described above).

      2. Admission of New General Partner. The New General Partner is hereby
admitted to the Partnership as a General Partner, and all of the Partners hereby
consent to such admission. The New General Partner shall have all of the rights
and obligations of the General Partner under the Agreement other than the
obligation to make capital contributions to the Partnership, which obligation
has been retained by the Old General Partner. Subject to the foregoing, the New
General Partner agrees to be bound by the Agreement and perform the duties of
the General Partner thereunder. The New General Partner agrees and acknowledges
that the economic interest in the Partnership owned by the Old General Partner
has been retained by the Old General Partner as described in Section 1 of this
Amendment, and that the economic interest of the New General Partner shall be as
specified in Section 3.01(b)(iii), described below. Subject to the foregoing,
all references in the Agreement to the General Partner shall be deemed to refer
to the New General Partner.


                                      -2-

      The New General Partner and the Old General Partner shall prepare, execute
and file an amendment to the Partnership's Certificate of Limited Partnership
and such other instruments as may be necessary, appropriate or convenient to
reflect the withdrawal as a general partner of the Old General Partner from the
Partnership, the admission of the New General Partner to the Partnership and the
other matters described in this Amendment.

      3. Amendment to Schedule A. The Agreement, including Schedule A thereto,
is hereby deemed to be amended to reflect the conversion of the interest of the
Old General Partner into a Limited Partner, and the admission of the New General
Partner to the Partnership.

      4. Amendment to Section 2.02. Section 2.02 of the Agreement is hereby
amended as follows:

      (a) Section 2.02(b) is hereby deleted, and the following is substituted
therefor:

            "Net Profits" and "Net Losses" mean the taxable income or loss, as
      the case may be, for a period as determined in accordance with Code
      Section 703(a) computed with the following adjustments:

                  (i) Items of gain, loss, and deduction shall be computed based
      upon the Carrying Values of the Partnership's assets (in accordance with
      Treasury Regulation Sections 1.704(b)(2)(iv)(g) and/or 1.704-3(d)) rather
      than upon the assets' adjusted bases for federal income tax purposes;

                  (ii) Any tax-exempt income received by the Partnership shall
      be included as an item of gross income;

                  (iii) The amount of any adjustments to the Carrying Values of
      any assets of the Partnership pursuant to Code Section 743 shall not be
      taken into account;

                  (iv) Any expenditure of the Partnership described in Code
      Section 705(a)(2)(B) (including any expenditures treated as being
      described in Section 705(a)(2)(B) pursuant to Treasury Regulations under
      Code Section 704(b)) shall be treated as a deductible expense;

                  (v) The amount of items of income, gain, loss or deduction
      specially allocated to any Partners pursuant to Section 2.05 shall not be
      included in the computation; and


                                      -3-
<PAGE>   86

                  (vi) The amount of any items of Net Profits or Net Losses
      deemed realized pursuant to Sections 2.03(b) and (c) shall be included in
      the computation.

            (b) The following definitions are hereby added at the end of Section
      2.02 of the Agreement:

                  (e) "Adjusted Capital Account" means, for each Partner, such
            Partner's Capital Account balance increased by such Partner's share
            of "minimum gain" and of "partner nonrecourse debt minimum gain" (as
            determined pursuant to Treasury Regulation Sections 1.704-2(g) and
            1.704-2(i)(5), respectively).

                  (f) "Partnership Capital" means an amount equal to the sum of
            all of the Partners' Adjusted Capital Account balances determined
            immediately prior to the allocation to the Partners pursuant to
            Sections 2.04(a)(ii) or 2.04(b)(i) of any Net Profits or Net Losses,
            increased by the aggregate amount of Net Profits then to be
            allocated to the Partners pursuant to Section 2.04(a)(ii) or
            decreased by the aggregate amount of Net Losses then to be allocated
            to the Partners pursuant to Section 2.04(b)(i).

            5. Amendment to Section 2.04. Section 2.04 of the Agreement is
      hereby amended to read in its entirety as follows:

                  2.04 Basic Allocations.

                        (a) Except as provided in Section 2.05 below (which
            shall be applied first), Net Profits of the Partnership for any
            relevant period shall be allocated as follows:

                              (i) First, to any Partners having negative
                  Adjusted Capital Account balances, in proportion to and to the
                  extent of such negative balances; and

                              (ii) The balance, if any, to the Partners in such
                  proportions and in such amounts as would result in the
                  Adjusted Capital Account balance of each Partner equaling, as
                  nearly as possible, such Partner's share of the then
                  Partnership Capital determined by calculating the amount the
                  Partner would receive if an amount equal to the Partnership
                  Capital were distributed to the Partners in accordance with
                  the provisions of Section 3.01(b) hereof.

                        (b) Except as provided in Section 2.05 below (which
            shall be applied first), Net Losses of the Partnership for any
            relevant period shall be allocated among the Partners as follows:

                              (i) First, to each Partner with a positive
                        Adjusted Capital Account balance, in the amount of such
                        positive balance; provided, however, that if the amount
                        of Net Losses to be allocated is less than the sum of
                        the Adjusted Capital Account balances of all Partners
                        having positive Adjusted Capital Account balances, then
                        the Net Losses shall be allocated to the Partners in
                        such proportions and in such amounts as would result in
                        the Adjusted Capital Account balance of each Partner
                        equaling, as nearly as possible, such Partner's share of
                        the then Partnership Capital determined as set forth in
                        Section 2.04(a) above; and

                              (ii) The balance, if any, 100% to the New General
                        Partner.

                        (c) If the amount of Net Profits allocable to the
            Partners pursuant to Section 2.04(a)(ii) or the amount of Net Losses
            allocable to them pursuant to Section 2.04(b)(i) is insufficient to
            allow the Adjusted Capital Account balance of each Partner to equal
            such Partner's share of the Partnership Capital, such Net Profits or
            Net Losses shall be allocated among the Partners in such a manner as
            to decrease the differences between the Partners' respective
            Adjusted Capital Account balances and their respective shares of the
            Partnership Capital in proportion to such differences.

                        (d) Allocations of Net Profits and Net Losses provided
            for in this Section 2.04 shall generally be made as of the end of
            the fiscal year of the Partnership; provided, however, that
            allocations of items of Net Profits and Net Losses described in
            clause (vi) of the definition of "Net Profits" and "Net Losses"
            shall be made at the time deemed realized as described in Section
            2.03.

            6. Amendment to Section 2.05. Section 2.05(e) of the Agreement is
      hereby deleted.

            7. Amendment to Section 3.01. Section 3.01 of the Agreement is
      hereby amended as follows:

            (a) Section 3.01(a) is hereby amended by adding thereto the
      following additional definitions:

                  "Net Invested Capital. "Net Invested Capital" means the
            excess, if any, of (i) the aggregate amount of the Subscribed
            Capital actually contributed by a


                                      -5-
<PAGE>   88

      Partner to the Partnership over (ii) the aggregate amount distributed to
      such Partner pursuant to Section 3.01(b)(i) below from time to time.

            Priority Return. "Priority Return" means, at any point in time, for
      any Partner, that amount which, when considered together with all amounts
      previously distributed to such Partner pursuant to Section 3.01(b)(ii),
      will result in such Partner having received distributions pursuant to such
      Section equal to an 8% cumulative return, compounded annually, on such
      Partner's weighted average Net Invested Capital."

      (b) Section 3.01(b) is hereby amended to read in its entirety as follows:

             "(b)  From and after December 14, 1995, Distributable Cash shall be
                   distributed to and among the Partners, at such times and in
                   such amounts as shall be determined by the General Partner
                   (but not less frequently than annually) as follows:

                   (i)   First, to the Partners in proportion to their
                         respective amounts of Net Invested Capital until the
                         Net Invested Capital of each Partner has been reduced
                         to zero;

                   (ii)  Second, to the Partners in proportion to their
                         respective amounts of Priority Return until the
                         Priority Return of each Partner has been reduced to
                         zero; and

                   (iii) The balance, if any, 75% to all Partners other than the
                         General Partner (which amount shall be allocated among
                         such Partners in proportion to their respective number
                         of Interests in the Partnership), and 25% to the
                         General Partner in its capacity as General Partner;
                         provided, however, that if at any time the Joint
                         Management Agreement has been terminated in accordance
                         with the terms thereof, from and after the date of such
                         termination, 100% of all amounts distributed pursuant
                         to this clause (iii) shall be distributed to the
                         Partners other than the General Partner (which amount
                         shall be allocated among such Partners in proportion to
                         their respective number of Interests in the
                         Partnership)."

      8. Sections 7.02(c) and 8.16 of the Agreement are hereby deleted in their
entirety.

      9. To the extent that any of the provisions of the Agreement is
inconsistent with the matters described herein or the transactions contemplated
hereby, the


                                       -6-
<PAGE>   89

Agreement is hereby amended to the extent reasonably necessary to effectuate
such matters and consummate such transactions.

      10. In all other respects, the Agreement is hereby ratified and confirmed.

      IN WITNESS WHEREOF, the undersigned, constituting all of the Partners of
the Partnership, have executed this Amendment as of the date set forth above.
