                    judgment:

                    (i)  if the General Partner reasonably determines an
                         adjustment is necessary or appropriate to reflect the

                         Partnership as of (1) the acquisition of an additional
                         interest in the Partnership by any new or existing

                         interest in the Partnership; and

                    (ii) as of the liquidation of the Partnership within the
                         meaning of Regulations Section 1.704-1(b)(2)(ii)(g);

               (c)  the Book Value of any Partnership asset distributed to any
                    Partner will be the gross fair market value of the asset on
                    the date of distribution; and

               (d)  the Book Values of Partnership assets will be increased or
                    decreased to reflect any adjustment to the adjusted basis of
                    the assets under Code Sections 734(b) or 743(b), but only to
                    the extent that the adjustment is taken into account in
                    determining Capital Accounts under Regulations Section
                    1.704-1(b)(2)(iv)(m), provided that Book Values will not be
                    adjusted hereunder to the extent that the General Partner
                    determines that an adjustment under clause (b) is necessary
                    or appropriate in connection with a transaction that would
                    otherwise result in an adjustment under this clause (d).

               (a), clause (b) or clause (d) above, Book Value will be adjusted
               by the Depreciation taken into account with respect to the asset

          Minimum Gain, then each Partner shall first be allocated items of
          Gross Income for such year (and, if necessary, subsequent years) in an
          amount equal to such Partner's share of the net decrease in such
          Minimum Gain during such year (as determined under Regulations Section
          1.704-2(g)(2)); provided, however, if there is insufficient Gross
          Income in a year to make the allocation specified above for all
          Partners for such year, the Gross Income shall be allocated among the
          Partners in proportion to the respective amounts they would have been
          allocated had there been an unlimited amount of Gross Income for such
          year.

          the Partner Nonrecourse Debt Minimum Gain, then each Partner shall
          first be allocated items of Gross Income for such year (and, if
          necessary, subsequent years) in an amount equal to such Partner's
          share of the net decrease in such Minimum Gain during such year (as
          determined under Regulations Section 1.7042(i)(4)); provided, however,
          if there is insufficient Gross Income in a year to make the allocation
          specified above for all Partners for such year, the Gross Income shall
          be allocated among the Partners in proportion to the respective
          amounts they would have been allocated had there been an unlimited
          amount of Gross Income for such year.

     4.9  Qualified Income Offset. Notwithstanding any other provision of this
          Agreement to the contrary (except Sections 4.7 and 4.8 which shall be

          unexpectedly receives an adjustment, allocation or distribution
          described in Regulations Section 1.7041(b)(2)(ii)(d)(4), (5) or (6),
          such Partner will be specially allocated items of Gross Income in an
          amount and manner sufficient to eliminate, to the extent required by

          Capital Account Deficit and shall be reallocated to the other
          Partners, subject to the limitations of this Section 4.10.

                                      -12-



     4.11 Net Loss from Partner Nonrecourse Debt. Any Net Loss or deductions
          attributable to Partner Nonrecourse Debt shall be allocated to the
          Partner who bears the economic risk of loss with respect to such debt.

     4.12 Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal Year or
          other period shall be allocated among the Partners in accordance with
          their Partnership Percentages.

     4.13 Code Section 754 Adjustments. To the extent an adjustment to the
          adjusted tax basis of any Partnership asset under Code Sections 734(b)
          or 743(b) is required to be taken into account in determining Capital
          Accounts under Regulations Section 1.704-1(b)(2)(iv)(m), the amount of
          the adjustment to the Capital Accounts will be treated as an item of
          gain (if the adjustment increases the basis of the asset) or loss (if
          the adjustment decreases the basis), and the gain or loss will be
          specially allocated to the Partners in a manner consistent with the
          manner in which their Capital Accounts are required to be adjusted
          under Regulations Section 1.704-1(b)(2)(iv)(m).

     4.14 Reversal of Mandatory Allocations. In the event that any Gross Income
          or Net Loss is allocated pursuant to Section 4.7 through 4.10,
          subsequent Gross Income, Net Profit or Net Loss (or items thereof)
          will first be allocated (subject to Sections 4.7 through 4.10) to the
          Partners in a manner which will result in each Partner having a
          Capital Account balance equal to that which would have resulted had
          the original allocation of Gross Income or Net Loss (or items thereof)
          pursuant to Sections 4.7 through 4.10 not occurred.

     4.15 Compliance with Code. The foregoing provisions of this Agreement
          relating to the allocation of Net Profit and Net Loss are intended to
          comply with Regulations under Section 704(b) of the Code and shall be
          interpreted and applied in a manner consistent with such Regulations.

     4.16 Tax Allocations -- Code Section 704(c). In accordance with Code
          Section 704(c) and the related Regulations, income, gain, loss and
          deduction with respect to any property contributed to the capital of
          the Partnership, solely for tax purposes, will be allocated among the
          Partners so as to take account of any variation between the adjusted
          basis to the Partnership of the property for federal income tax
          purposes and the initial Book Value of the property. If the Book Value
          of any Partnership asset is adjusted under Section 1.1.7, subsequent
          allocations of income, gain, loss and deduction with respect to that
          asset will take account of any variation between the adjusted basis of
          the asset for federal income tax purposes and its Book Value in the
          same manner as under Code Section 704(c) and the related Regulations.
          Any elections or other decisions relating to allocations under this
          Section 4.16 will be made in any manner that the General Partner
          determines reasonably reflects the purpose and intention of this
          Agreement. Allocations under this Section 4.16 are solely for purposes
          of federal, state and local taxes and will not affect, or in any way
          be taken into account in computing, any Partner's

                                      -13-



          Capital Account or share of Net Profit, Net Loss, or other items or
          distributions under any provision of this Agreement.

     4.17 Allocation on Transfer. If any interest in the Partnership is
          transferred, or is increased or decreased by reason of the admission
          of a new Partner or otherwise, during any Fiscal Year, the Partnership
          shall make an interim closing of its books as of the effective date of
          such date of transfer or admission and shall allocate Net Income or
          Net Loss or items thereof based on such interim closing. All transfers
          of interests or admissions or exclusions of Partners occurring at any
          time during a month shall be deemed effective as of the opening of
          business on the first day of the subsequent month.

     4.18 Minimum Interest of General Partner. Notwithstanding any indication to
          the contrary, the General Partner's interest in each item of
          Partnership income, gain, loss, deduction and credit shall be not less
          than 1%, except as otherwise required pursuant to Section 704(b) or
          Section 704(c) of the Code.

          contributed pursuant to Regulations Section 1.704-1(b)(2)(iv)(c)), the
          Book Value of any property contributed by such Partner to the capital
          of the Partnership (net of any liabilities secured by such property

          or secured by any Partnership property distributed to the Partner.
          There shall be charged against each Partner's Capital Account the
          amount of all cash distributed to such Partner by the Partnership (or

          1.704-1(b)(2)(iv)(c)), the Book Value of any property distributed to

          Partnership.

     5.2  Adjustment for In-Kind Distributions. If the Partnership at any time
          distributes any of its assets in-kind to any Partner, the Capital
          Account of each

                                      -14-



          Partner shall be adjusted as contemplated by Section 4.5, as
          applicable, to account for that Partner's allocable share (as
          determined under Article 4 above) of the Net Profit or Net Loss that
          would have been realized by the Partnership had it sold the assets
          distributed for their respective fair market values immediately prior
          to their distribution.

     5.3  Property Revaluation. The Capital Accounts shall be adjusted to
          reflect a revaluation of Partnership property to its fair market value
          on the date of adjustment upon the occurrence of any of the following
          events:

          5.3.1 an increase in any new or existing Partner's Partnership
               Percentage resulting from the contribution of money or property
               by such Partner to the Partnership including a conversion of debt
               into Partnership interests,

          5.3.2 any reduction in a Partner's Partnership Percentage resulting
               from a distribution to such Partner in consideration of all or
               part of his Partnership interest, unless such distribution is pro
               rata to all Partners in accordance with their respective
               Partnership Percentages, and

          5.3.3 whenever else allowed under Regulations Section
               1.704-1(b)(2)(iv)(f).

          The adjustments to Capital Accounts shall reflect the manner in which
          the unrealized Net Profit or Net Loss inherent in the property would
          be allocated if there were a disposition of the Partnership's property
          at its fair market value on the date of adjustment.

     5.4  Interpretation. It is the intention of the Partners that the Capital
          Accounts be maintained strictly in accordance with the capital account
          maintenance requirements of Regulations under Code Section 704(b). The
          foregoing provisions and the other provisions of this Agreement
          relating to the maintenance of the Capital Accounts are intended to
          comply with such Regulations and shall be interpreted and applied in a
          manner consistent with such Regulations and any amendment or successor
          provision thereto. The General Partner also shall make any appropriate
          modifications if unanticipated events might otherwise cause this
          Agreement not to comply with the Regulations, so long as such changes
          would not cause a material change in the relative economic benefits of
          the Partners under this Agreement.

     5.5  Obligation to Repay or Restore. If the Limited Partner has received
          distributions of Net Cash Flow or Net Proceeds of a Capital
          Transaction, it may be obligated under the Act to repay or restore to
          the Partnership all or a portion of the amount received if such
          distributions cause the fair market value of the Partnership's assets
          to be less than the Partnership's liabilities. Subject to the
          foregoing requirement, the Limited Partner shall not be required to
          pay to the Partnership or to any other Partner any deficit or negative
          balance which may exist from time to time in its Capital Account;

                                      -15-



          provided, however, in the event the Limited Partner erroneously
          receives distributions in excess of his interest in such distributions
          as specified in Sections 4.1, 4.2 and 4.3 hereof ("Excess
          Distributions"), then, as between the Partners but not for the benefit
          of other Persons. such Partner shall be indebted to the Partnership
          for such Excess Distributions, and such indebtedness shall be payable
          on terms or on demand as may be prescribed by the General Partner. The
          General Partner shall contribute, prior to the dissolution and
          liquidation of the Partnership, an amount equal to the lesser of (a)
          an amount which will cause the total Capital Contributions made by the
          General Partner during the Partnership Term to equal one percent (1%)
          of the total Capital Contributions made to the Partnership (including
          the Capital Contribution to be made by the General Partner pursuant to
          this Section 5.5), or (b) the deficit balance in its Capital Account
          as of the date of such dissolution and liquidation.

     5.6  Tax Elections. The General Partner is authorized, in its reasonable
          discretion, to make all elections permitted or required of the
          Partnership under Regulations Section 1.704-1, Code Section 754 and
          any other provisions of the Code.

                                   ARTICLE 6.

                               OPERATING EXPENSES

     6.1  Operating Expenses and Reimbursements. The Partnership shall bear (or
          reimburse the General Partner for its payment of) all costs and
          expenses of every kind and description incurred in connection with the
          organization, operation, liquidation and dissolution of the
          Partnership including, but not limited to, travel expenses, fees of
          consultants, accountants, and attorneys, fees and expenses of the
          preparation of quarterly unaudited financial statements, the annual
          audit, if any, and tax returns of the Partnership, interest on
          indebtedness of the Partnership, and fees and expenses incurred in any
          litigation by or against the Partnership.

                                   ARTICLE 7.

                 ADMISSION OF PARTNERS; ASSIGNMENT OF INTERESTS

     7.1  Admission of Additional Partners. Other than TXI Operating Trust, a

          Industries Holdings, Inc., a Delaware corporation and Texas Industries
          Trust, a Delaware business trust, which shall be admitted to the
          Partnership pursuant to the provisions of Section 7.2.3 hereof, no
          additional partners shall be admitted to the Partnership.

          7.2.1 Except as provided in Section 7.2.2 and 7.2.3, no Partner shall
               sell, assign, pledge, mortgage, or otherwise dispose of or
               Transfer, in whole or in part, its Partnership interest or its
               share of the Partnership's capital, assets or property or enter
               into any agreement, the result of which would be for another
               Person to become directly or indirectly interested in the
               Partnership.

          7.2.2 The general Partnership interest of TXI Texas, Inc. may be
               transferred to TXI Operating Trust. Upon the effective time of
               the above transfer, TXI Texas, Inc. shall withdraw from the
               Partnership and TXI Operating Trust shall be admitted as a
               Partner with the same Partnership and TXI Operating Trust shall
               be admitted as a Partner with the same Partnership interest as
               TXI Texas, Inc.

          7.2.3 The limited Partnership interest of TXI Industries, Inc. may be
               transferred to Texas Industries Holdings, Inc. (the "Initial
               Transfer") and the same Partnership interest may be transferred
               by Texas Industries Holdings, Inc. to Texas Industries Trust (the
               "Subsequent Transfer"). Upon the effective time of the Initial
               Transfer, TXI Industries, Inc. shall withdraw from the
               Partnership and Texas Industries Holdings, Inc. shall be admitted
               as a Partner with the same Partnership interest as TXI
               Industries, Inc. and upon the effective time of the Subsequent
               Transfer Texas Industries Holdings, Inc. shall withdraw and Texas
               Industries Trust shall be admitted as a Partner with the same
               Partnership interest as Texas Industries Holdings, Inc..

                                   ARTICLE 8.

          8.1.3 Actions Requiring Limited Partner Approval. Notwithstanding

               (a)  Transfer all or substantially all of the Partnership's
                    assets, whether in one transaction or a series of related
                    transactions;

               (b)  Effect the reorganization, merger or consolidation of the

               (c)  Any act in contravention of this Agreement;

               (d)  Any act which would make it impossible to carry on the
                    ordinary business of the Partnership, other than a Transfer
                    of all or substantially all of the assets of the Partnership
                    authorized under Section 8.1.3(a) or a reorganization,
                    merger or consolidation authorized under Sections 8.1.3(b);

               (f)  Incur any debt, on behalf of the Partnership or otherwise,
                    for which the Limited Partner shall be directly or
                    personally liable to any extent.

     8.2  Authority as to Third Persons. Notwithstanding Section 8.1.3, the
          signed statement of the General Partner reciting that it has the
          authority or necessary approval of the Limited Partner for any action,
          as to any third Person, will be conclusive evidence of the authority
          of the General Partner to take that action and of compliance with
          Section 8.1.3, if applicable. The Limited Partner will promptly
          execute instruments determined by the General Partner to be
          appropriate to evidence the authority of the General Partner to
          consummate any transaction permitted by this Agreement.

     8.3  Compensation and Expenses of the General Partner. Except as provided
          below, the General Partner will not receive any compensation from the
          Partnership for serving as General Partner, but all expenses incurred
          by the General Partner in connection with its service as General
          Partner (including

                                      -20-



          without limitation charges for legal, accounting, data processing,
          administrative, executive, tax and other services rendered) will be
          paid or promptly reimbursed by the Partnership. The Partnership shall
          also reimburse the General Partner for all payroll expenses of the
          General Partner incurred by the General Partner in connection with the
          Partnership's operations including but not limited to the following:
          compensation; employee benefits including medical, health and deferred
          compensation benefits; and payroll taxes. After the end of each Fiscal
          Year of the Partnership, the General Partner shall be paid a
          guaranteed payment for the preceding Fiscal Year in an amount equal to
          the excess of (i) an amount sufficient to generate a ten percent (10%)
          internal rate of return on its unreturned invested capital in the
          Partnership determined for financial reporting purposes over (ii) the
          amount of allocations of Net Profit to the General Partner pursuant to
          Section 4.6 for such Fiscal Year. Nothing contained in this Section
          8.3 is intended to affect the distributions to the General Partner or
          the amounts that may be payable to the General Partner by reason of
          its interest in the Partnership.

     8.4  Covenants of the General Partner. The General Partner shall devote
          such time, effort, and attention as may be reasonably necessary,
          advisable, or appropriate to manage and direct the operations,
          business and affairs of the Partnership.

     8.5  Limitations on Authority. The authority of the General Partner over
          the conduct of the operations, business, and affairs of the
          Partnership shall be subject only to the Act and such further
          limitations as are expressly stated in this Agreement.

     8.6  No Withdrawal From Partnership. Except as contemplated by this
          Agreement, no Partner may withdraw from the Partnership at any time.

                                   ARTICLE 9.

                         DISSOLUTION OF THE PARTNERSHIP

     9.1  Dissolution. The Partnership shall be dissolved upon the happening of
          any of the following events:

               Partner;

               disposes of or encumbers, directly or indirectly, all or any part
               of its interest, except as permitted in this Agreement, or allows
               such sale, assignment, transfer, pledge, disposition or
               encumbrance to occur.

          9.1.6 the occurrence of any other event causing the dissolution of a
               limited partnership under the laws of the State of Delaware.

     9.2  Continuation. Upon the Bankruptcy, dissolution or removal of the
          General Partner, the business of the Partnership will be continued if
          within 90 calendar days the Limited Partner elects by written action
          to continue the business of the Partnership and designate one or more
          Persons to be a General Partner of the Partnership. If the business of
          the Partnership is continued, the interest of the General Partner will
          be converted to that of a limited partner. If the Limited Partner
          fails to continue the Partnership's business as provided in this
          Section 9.2, the Partnership will be liquidated under Section 9.4.

     9.3  Events Affecting a Limited Partner. The Bankruptcy, liquidation,
          dissolution, reorganization, merger, sale of substantially all the
          stock or assets of, or other change in the ownership or nature of the
          Limited Partner shall not dissolve the Partnership.

     9.4  Liquidation Procedures.

          9.4.1 Upon dissolution of the Partnership the General Partner or, if
               there is no General Partner, such Person or Persons as the
               Limited Partner shall designate as liquidating trustees shall
               commence immediately to wind up the affairs of the Partnership.
               The General Partner or such liquidating trustees shall use their
               best judgment as to when to dispose of the Partnership's assets
               or to make distributions in-kind in order to maximize the return
               to the Partners from such assets.

          9.4.2 The assets of the Partnership remaining after payment of the
               costs and expenses of winding up shall be applied in the
               following priority:

               (a)  To payment of the costs and expenses of the winding up.
                    liquidation and termination of the Partnership;

               (b)  to the creditors of the Partnership, other than Partners,
                    all amounts due them from the Partnership in the order of
                    priority established by law;

               (c)  to the Partners, all amounts due them in repayment of any
                    loans to the Partnership pursuant to Section 3.3;

               (d)  To the establishment of any reserves deemed appropriate by
                    the General Partner or liquidating trustees for any
                    liabilities or obliga-

                                      -22-



                    tions of the Partnership, which reserves will be held for
                    the purpose of paying liabilities or obligations and, at the
                    expiration of a period the General Partner or liquidating
                    trustees deems appropriate, will be distributed in the
                    manner provided in Section 9.4.2(e); and,

               (e)  To the payment to the Partners of the positive balances in
                    their respective Capital Accounts, pro rata, in proportion
                    to the positive balances in those Capital Accounts after
                    giving effect to all allocations and distributions under
                    Article 4 for all prior periods, including the period during
                    which the process of liquidation occurs.

               If the General Partner or the liquidating trustees, in their sole
               discretion, deem it not feasible or desirable to liquidate to
               each Partner its allocable share of each asset to be distributed
               in-kind, the General Partner or the liquidating trustees may
               allocate and distribute specific assets to one or more Partners
               as the General Partner or the liquidating trustees shall
               reasonably determine to be fair and equitable, taking into
               consideration, among other things, the value of the assets, the
               indebtedness secured by the assets and the tax consequences of
               the proposed distribution upon each of the Partners. Any
               distributions in-kind shall be subject to such conditions
               relating to the disposition and management thereof as the General
               Partner or the liquidating trustees deem reasonable and
               equitable.

     9.5  Termination. The Partnership shall terminate when all property owned
          by the Partnership has been disposed of, and any proceeds from the
          sale or other disposition of all of the Partnership property, after
          payment of or provision for all liabilities to creditors of the
          Partnership, has been distributed to the Partners.

     9.6  No Petition for Dissolution. The Partners agree that irreparable
          damage would be done to the goodwill and reputation of the Partnership
          if any Partner should bring an action in any court to dissolve the
          Partnership and to have a liquidator or receiver for the Partnership
          appointed. Care has been taken in this Agreement to provide what the
          parties feel is fair and just payment in liquidation of the interest
          of all Partners. Accordingly, each Partner hereby waives and renounces
          its right to file or pursue any such petition for dissolution of the
          Partnership or the partition of any Partnership property, or to seek
          the appointment by any court of a liquidator or receiver for the
          Partnership.

     9.7  Compliance with Timing Requirements of Treasury Regulations.
          Notwithstanding anything in this Article 9 to the contrary, in the
          event the Partnership is "liquidated" within the meaning of
          Regulations Section 1.704-l(b)(2)(ii)(g), distributions will be made
          to the Partners who have positive

                                      -23-



          Capital Account balances pursuant to Section 9.4 in a manner that
          complies with Regulations Section 1.704-1(b)(2)(ii)(b)(2). However, a
          liquidation occurring as a result of a Partnership termination, as
          defined in Section 708(b)(1)(B) of the Code, will not require an
          actual distribution of Partnership assets, but will instead be treated
          as a constructive liquidation and reformation in the manner described
          in Regulations Section 1.708-1(b)(1)(iv).

                                   ARTICLE 10.

          timely manner to each of the Partners. In the event of an income tax
          audit of the Partnership or any judicial or administrative proceeding
          in connection with the income tax returns of the Partnership, the Tax
          Matters Partner shall be authorized to act for and, to the extent
          provided by the Code, its decision shall be binding upon the
          Partnership and the Partners. The books and records of the Partnership
          shall be kept in accordance with generally accepted accounting
          principles.

          faith, and such determination will be binding on the Partners.

     10.3 Supervision: Inspection of Books. Proper and complete books of account
          of the business of the Partnership shall be kept under the supervision
          of the General Partner at the principal place of business of the
          Partnership. Such books shall be open to inspection by the Limited
          Partner, or its accredited representatives, at any reasonable time
          during normal business hours.

     10.4 Quarterly Reports. The General Partner shall transmit to the Limited
          Partner within thirty (30) days after the close of each quarter, or as

          accounting from its books without audit and subject to year-end
          adjustments.

     10.5 Annual Report: Financial Statements. The General Partner shall
          transmit to the Limited Partners within one hundred twenty (120) days

          thereafter, financial statements of the Partnership prepared in
          accordance with the accrual method of accounting, including an income
          statement for the year then ended, a balance sheet as of the end of
          such year, and a statement of changes in the Partners'

                                      -24-



          Capital Accounts. If the General Partner, in its sole discretion,
          determines that audited financial reports are appropriate, then the
          financial statements shall be audited by an independent public
          accounting firm selected by the General Partner.

     10.6 Consent in Lieu of Meeting. Any action which may be taken by the
          Partners at a meeting may be effected through the execution of written
          consents by the requisite Partnership Percentage of the Partners.

     10.7 Withholding. Notwithstanding any provision in this Agreement to the
          contrary, the General Partner may withhold from any distribution or
          amount due to the Limited Partner any amounts required to be withheld
          pursuant to any applicable federal, state, or local tax requirements,
          with such withheld amount treated as if it was distributed to the
          Limited Partner. The determination of the General Partner as to the
          necessity of such withholding shall be binding upon the Limited
          Partner.

                                   ARTICLE 11.

          General Partner shall cause the Partnership to be qualified, formed,
          reformed or registered under the limited partnership laws, assumed or
          fictitious name statutes or similar laws in any jurisdiction in which
          the Partnership owns property or transacts business if such
          qualification, formation, reformation or registration is necessary in
          order to protect the limited liability of the Limited Partner or to
          permit the Partnership lawfully to own property or transact business
          as a limited partnership. The General Partner shall execute, file and
          publish all such certificates, notices, statements or other
          instruments appropriate to conduct the business of the Partnership and
          to maintain the limited liability of the Limited Partner.

     11.2 Other Instruments and Acts. The Partners agree to execute any other

     11.4 Governing Law. This Agreement shall be governed by and construed under
          the laws of the State of Delaware, without giving effect to the
          principles of conflict of laws.

          notice to the other Partners and, in the case of the Partnership, to
          its principal office designated in Section 2.4.

     11.6 Power of Attorney. The Limited Partner appoints the General Partner
          its attorney-in-fact, with full power of substitution and

               (b)  Any instrument that the General Partner deems appropriate in
                    order to qualify the Partnership to do business in any
                    jurisdiction and any other instrument relating to the

               (c)  All certificates and other instruments that may be

                                      -26-



          The power of attorney granted under this Section 11.6 is coupled with

          Partner or the Transfer of its Partnership interest.

     11.7 Amendment.

          11.7.1 Except for such amendments as result from the operation of the
               various provisions of this Agreement, this Agreement may be
               amended only with the written consent of the Limited Partners and
               the General Partner.

          11.7.2 The General Partner, acting alone, may make ministerial changes
               in the Partnership Agreement for the purpose of correcting errors
               and inconsistencies and to comply with federal, state and local
               rules, regulations and laws, provided that the liability of the
               Limited Partner for Partnership debts shall not be increased by
               such amendment nor shall the right of the Limited Partner to
               Partnership allocations or distributions be adversely affected
               thereby.

     11.8 Entire Agreement. This Agreement shall constitute the entire agreement
          of the Partners and supersede all prior agreements between the
          Partners with respect to the Partnership.

     11.9 Titles; Subtitles. The titles and subtitles used in this Agreement are
          used for convenience only and shall not be considered in the
          interpretation of this Agreement.

     11.10 Exculpation. Neither the General Partner, nor any of its officers,
          directors, employees, agents, or Affiliates, shall be liable to the
          Limited Partner or the Partnership for any action taken or failure to
          act on behalf of the Partnership within the scope of authority
          conferred on the General Partner by this Agreement, or by law, or done
          in reliance in good faith on the opinion of legal counsel, except in
          the case of (i) its willful breach of a material provision of the Act
          or this Agreement; (ii) the breach of its fiduciary responsibilities
          to the Partnership or the Limited Partner; or, (iii) its gross
          negligence in connection with the business and affairs of the
          Partnership.

     11.11 Indemnification of the General Partner. The Partnership, to the
          extent of its assets legally available for that purpose, will
          indemnify and hold harmless the General Partner and any partner,
          shareholder, director, officer, agent, affiliate and professional or
          other advisor of the General Partner (collectively, the "Indemnified
          Persons"), from and against any and all loss, damage, expense
          (including without limitation reasonable fees and expenses of
          attorneys and other advisors and any court costs incurred by any
          Indemnified Person) or liability by reason of anything any Indemnified
          Person does or refrains from doing for, or in connection with the
          business or affairs of, the Partnership,

                                      -27-



          except to the extent that the loss, damage, expense or liability
          results from (a) the Indemnified Person's gross negligence, willful
          misconduct or knowing violation of law, or (b) the Indemnified
          Person's breach of any fiduciary responsibilities to the Partnership
          or the Limited Partner. These indemnification rights are in addition
          to any rights the Indemnified Persons may have against third parties.

          Notwithstanding anything in this Agreement to the contrary, no Partner
          shall be obligated to contribute any amount to the Partnership in
          order to satisfy the Partnership's indemnification obligations under
          this Section 11.11, such obligations being limited at all times to the
          assets of the Partnership.

     11.12 Limitation of Liability of the Limited Partners. No Limited Partner
          shall be bound by, or by personally liable for, the expense,
          liabilities, obligations of the Partnership in excess of its Capital
          Contributions to the Partnership plus such additional amounts
          determined pursuant to Section 5.5.

     11.13 Ambiguities. The General Partner shall have full power and authority
          to resolve questions of interpretation and construction arising under
          this Agreement, and its resolution of such ambiguities or questions
          shall be final and binding on the Partnership and all of its Partners
          and their permitted transferees, successors, assigns and legal
          representatives.

     11.14 No Right to Partition. Each Partner hereby irrevocably waives any and
          all rights that it may have to maintain or institute an action for
          partition of the Partnership assets.

     IN WITNESS WHEREOF, the Partners have executed this Agreement as of the
date first above written.
