            3.2.1 Each Partner shall make contributions to the capital of the

as "Committed Capital." Each Partner shall make its contribution in cash. The
General Partner will commit to contribute an amount equal to at least 1% of the

Partner in all respects with respect to such commitment. The General Partner may
commit to contribute additional amounts as a Limited Partner in its discretion.

            3.2.2 Notwithstanding Section 3.2.1 above, if, at any time before
any contribution to the capital of the Partnership required by Section 3.3 below
is due, a Limited Partner shall obtain and deliver to the General Partner an
opinion of counsel reasonably satisfactory to the General Partner that (a) there
is a material likelihood that the payment by such Limited Partner of such
additional contribution will be unlawful, or (b) such Limited Partner is subject
to ERISA and either (i) such additional contribution could be found to violate
any ERISA provision, (ii) the assets of the Partnership may be deemed to
constitute the assets of such Limited Partner under ERISA, or (iii) the trustees
or other fiduciaries of such Limited Partner may be deemed under ERISA to have
delegated investment discretion over plan assets (as defined by ERISA) to any
Person which is not an "investment manager" (as defined by ERISA), then such

                                      -5-
<PAGE>

Limited Partner shall have no further obligation to make such additional
contribution, the Committed Capital of such Limited Partner shall be reduced to
an amount equal to its Capital Contribution, and such Limited Partner shall not,
by reason of its failure to make such additional contribution, be deemed a
Defaulting Limited Partner pursuant to Section 3.7 hereof; provided, that the
General Partner subsequently may (but shall not be obligated to) accept
additional Capital Contributions from such Limited Partner upon receipt of an
opinion of counsel reasonably satisfactory to the General Partner that the legal
conditions described in this Section 3.2.2 no longer exist.

     3.3    Timing of Capital Contributions. Each Partner shall contribute one-
third of its Committed Capital to the Partnership concurrently with the First
Closing or the appropriate Subsequent Closing, as the case may be. An additional
one-third of each Partner's Committed Capital shall be contributed to the
Partnership on the first anniversary of the First Closing and the final one-
third of each Partner's Committed Capital shall be contributed to the
Partnership on the second anniversary of the First Closing.

     3.4    Interest and Return of Capital Contributions. No Partner shall be
entitled to interest on any Capital Contribution and no Partner shall have the
right to withdraw or to demand the return of all or any part of its Capital
Contribution, except as specifically provided in this Agreement.

     3.5    Additional Capital Contributions. No Limited Partner shall be
required to make total contributions to the capital of the Partnership in excess
of its Committed Capital, except as set forth in Section 3.7.3 hereof.

     3.6    Deficit Funding. Notwithstanding any other provision of this
Agreement, if, upon dissolution and liquidation of the Partnership, the General
Partner has received distributions over the life of the Partnership (other than
in respect of its interest as a Limited Partner) in excess of (i) 5% of the
Realized Investment Gains less Realized Investment Losses of the Partnership
multiplied by a fraction equal to the aggregate Capital Contributions of all
Class A Limited Partners divided by the total Capital Contributions of all of
the Limited Partners, plus (ii) 20% of the Realized Investment Gains less
Realized Investment Losses of the Partnership multiplied by a fraction equal to
the aggregate Capital Contributions of all Class B Limited Partners divided by
the total Capital Contributions of all of the Limited Partners, then the General
Partner shall contribute such excess to the Partnership. Such amounts shall be
divided among the Class A and Class B Limited Partners. The amount payable to
each class of Limited Partner shall be equal to the amount received by the
General Partner in excess of the amounts determined in (i) and (ii) above,
respectively.

     3.7    Default by Limited Partners. In the event any Limited Partner fails
for any reason to make a contribution of Committed Capital pursuant to Section
3.3 hereof when due, and fails to make such contribution within thirty (30) days
after receiving written notice that such payment is overdue, such Limited
Partner shall be a "Defaulting Limited Partner," the overdue payment shall be a
"Delinquent Payment" and the rights of the Partners and the Partnership shall be
as follows:

            3.7.1 Within ten (10) days after the designation of Defaulting

such contribution of Committed Capital (a "Nondefaulting Limited Partner"). The
Default Notice shall specify:

                  (d) the Nondefaulting Limited Partner's pro rata share of (a),
     (b) and (c) above.

            3.7.2 Each Nondefaulting Limited Partner shall have the right to
acquire its pro rata share (based on the proportion of its Committed Capital to
the total Committed Capital of all Nondefaulting Limited Partners) of the
Defaulting Limited Partner's interest in the Partnership by giving written
notice to the General Partner of such election within thirty (30) days after
receipt of the Default Notice and such Nondefaulting Limited Partner shall do
the following to acquire such interest:

                  (a) within sixty (60) days after such election, pay to the
     Partnership for transfer to the Defaulting Limited Partner the
     Nondefaulting Limited Partner's pro rata share of the lesser of:

                        (i) fifty percent (50%) of the Defaulting Limited
            Partner's Capital Account as of the date of default, or

                        (ii) fifty percent (50%) of the Defaulting Limited
            Partner's share of the Estimated Value of the Fund determined most
            recently pursuant to Section 11.4 hereof;

                  (b) pay to the Partnership the Nondefaulting Limited Partner's
     pro rata share of the Delinquent Payment; and

                  (c) agree to pay the Nondefaulting Limited Partner's pro rata
     share of any remainder of the Defaulting Limited Partner's Committed

            Upon compliance by a Nondefaulting Limited Partner with this Section
3.7.2 and expiration of the sixty (60) day period specified in Section 3.7.2(a),
the Defaulting Limited Partner shall have no further interest in the portion of
its interest in the Partnership acquired by such Nondefaulting Limited Partner.

            3.7.3 If all of the Defaulting Limited Partner's interest is not
acquired by the Nondefaulting Limited Partners pursuant to Section 3.7.2 above,
the General Partner may elect, in its sole discretion, one or more of the
following remedies in addition to any other rights or remedies of the
Partnership:

<PAGE>

                  (a) to commence legal proceedings against the Defaulting

     expenses of collection, including attorneys' fees;

                  (b) to take such action as necessary to require the withdrawal
     of the Defaulting Limited Partner as a Limited Partner in the Partnership
     pursuant to Section 8.6 hereof, except that the amount to be paid to the
     Defaulting Limited Partner shall be the lesser of the amounts determined
     under Section 3.7.2(a)(i) or (ii) above less all amounts previously paid to
     such Defaulting Limited Partner under Section 3.7.2(a) above; or

                  (c) to permit and authorize any Limited Partner or Limited
     Partners or any other party desiring to do so, on a pro rata or any other
     basis, to acquire the remainder of the Defaulting Limited Partner's entire
     interest in the Partnership by: paying to the Partnership for transfer to
     the Defaulting Limited Partner within sixty (60) days after such
     authorization an amount equal to the lesser of fifty percent (50%) of the
     Defaulting Limited Partner's Capital Account as of the date such Limited
     Partner became a Defaulting Limited Partner or fifty percent (50%) of the
     Defaulting Limited Partner's share of the Estimated Value of the Fund as

continue to share in any Net Losses. Allocations of Net Income or Net Losses to
a Defaulting Limited Partner shall be made in accordance with Section 4.5
hereof. Notwithstanding the provisions of Section 3.7, the General Partner may
permit a default to be cured by a Defaulting Limited Partner on such terms and
conditions as it deems appropriate in its sole discretion.

            3.7.5 Each Limited Partner acknowledges by its execution hereof that
it has been admitted to the Partnership in reliance upon its agreements and
covenants in this Agreement, that the General Partner and the Partnership may
have no adequate remedy at law for a breach hereof and that any reduction in a
Limited Partner's interest in the Partnership as a result of such Limited
Partner's breach hereof is intended as liquidated damages and not as a penalty
by reason of the fact that the damages resulting from a breach hereof may be
impossible to ascertain at the time hereof or of such breach. Each Limited
Partner agrees that if it becomes a Defaulting Limited Partner it hereby
appoints the General Partner its attorney-in-fact to execute such documents and
enter into such agreements as determined by the General Partner to be necessary
in order to effect the withdrawal of such Limited Partner or the sale of such
Limited Partner's interest in the Partnership pursuant to this Section 3.7.

          the Capital Contributions of all Class B Limited Partners in the
          aggregate (on such date) and 20% to the Capital Account of the General
          Partner.

               (e) Notwithstanding paragraph (d) above, Excess Losses (as
     hereinafter defined) will be debited against the Capital Accounts of the
     Class A Limited Partners or Class B Limited Partners pro rata (i) so that
     the ratio of the aggregate Capital Accounts of all of the Class A Limited
     Partners to the Capital Accounts of all Limited Partners and the ratio of
     the aggregate Capital Accounts of all of the Class B Limited Partners to
     the Capital Accounts of all Limited Partners equal the ratios of the
     Capital Contributions of the Class A Limited Partners and Class B Limited
     Partners to the total Capital Contributions of all Limited Partners,
     respectively, and then (ii) between the Class A Limited Partners and Class
     B Limited Partners based on their classes' respective percentage shares of
     the total Capital Contributions of such classes of Partners. With respect
     to each Accounting Period thereafter, 100% of net income described in (d)
     above will be credited to the Capital Accounts of the Limited Partners in
     the reverse order as Excess Losses were allocated in the prior sentence,
     until the Excess Losses have been recouped from allocations of income
     pursuant to (c) and (d), at which time the allocations for income set forth
     in (d) above will be reinstated. "Excess Losses" shall mean those losses
     which, when allocated, will reduce the General Partner's Capital Account to
     a negative amount which is less than an amount equal to zero minus all
     prior distributions to the General Partner.

               (f) If Limited Partners are admitted subsequent to the First
     Closing, the Capital Accounts of the Limited Partners shall be adjusted to
     reflect the allocation of the Management Fee and the organizational
     expenses of the Partnership as provided in Section 4.4.

               (g) Any amounts distributed (including the fair market value of
     any Securities distributed in-kind as determined pursuant to Section 11.4
     as of the date of such distribution) to the Partners will be debited
     against their Capital Accounts.

               (h) The General Partner will adjust the Partnership's Capital
     Accounts at the end of each Accounting Period and may adjust them more
     often if circumstances make it advisable in the General Partner's sole
     discretion. Any Unrealized Investment Gain or Unrealized Investment Loss
     with respect to Securities being distributed in kind to all Partners as of
     the date of such distribution shall be credited or debited to the Capital
     Accounts of the Partners in accordance with Sections 4.2(d) and (e).

     4.3    No Interest on Capital Accounts.  No Partner shall receive interest
on the amount credited to such Partner's Capital Account.

     4.4    Allocation of Net Income and Net Losses.  The Net Income and Net
Losses of the Partnership will be allocated, for federal, state and local income
tax purposes, among the Partners in accordance with the allocation of items of
income and loss among the Partners for purposes of computing their Capital
Accounts, except as otherwise provided in the Code or other applicable law. If
Limited Partners are admitted subsequent to the First Closing pursuant to one or
more Subsequent Closings, the books of the Partnership shall be closed
immediately before each Subsequent Closing.  Those expenses of

                                      -10-
<PAGE>

the Partnership attributable to the Limited Partners admitted at each Subsequent
Closing, including such Partners' shares of the Management Fee, organizational
expenses and any other expenses incurred by the Partnership, shall be allocated
pro rata to such Limited Partners in accordance with their Capital
Contributions. The General Partner will cause the Partnership's tax returns to
be prepared within 120 days after the end of each of its fiscal years, and will
furnish appropriate tax forms and schedules (for example, Schedule K-1) to all
Partners.

     4.5    Allocations Among Limited Partners During Year in Which Transfer of
Partnership Interest Occurs.  If a Limited Partner transfers all or part of its
interest in the Partnership during any year or withdraws or is removed from the
Partnership pursuant to the terms of this Agreement, Net Income or Net Losses
and items thereof shall be allocated between the transferor and the transferee
(or among all of the other Partners in the event of withdrawal or removal) based
upon the respective portions of the year that the transferor or transferee held
such interest without regard to the result of Partnership operations during
particular portions of such year.

                                 Distributions

     5.1    Targeted Distributions During Term of Partnership.  Prior to
dissolution of the Partnership and no later than ninety (90) days after the
close of each year, the General Partner shall, after setting aside appropriate
reserves for anticipated obligations and commitments of the Partnership that are
determined to be advisable in its sole discretion, attempt to cause the
Partnership to distribute cash in an amount which, at the time of such
distribution, when added to all prior distributions, is equal to forty percent
(40%) of the Net Income, if any, of the Partnership from inception.  The General
Partner may, in its sole discretion, adjust the rate of such targeted
distribution provided for in this Section 5.1 from time to time in light of any
changes made to the tax rates applicable to individuals and corporations under
the Code.  Distributions pursuant to this Section 5.1 shall be made among the
Partners pro rata in the same proportions that Net Income is or has been
allocated among the Partners.  All other cash of the Partnership not distributed
pursuant to this Section 5.1 may be retained in the Partnership and invested or
applied to pay Partnership expenses pursuant to this Agreement; provided,
however, that after the fifth anniversary of the First Closing the Partnership
shall not invest cash generated from the sale of Securities (excluding Liquid
Investments as defined by Section 9.1 hereof).

     5.2    Other Distributions During Term of Partnership.

          5.2.1  In addition, prior to dissolution of the Partnership, subject
to the distributions pursuant to Section 5.1 hereof, the General Partner in its
sole discretion, may, but shall not be obligated to, distribute such assets of
the Partnership, whether in cash or in kind, as it may from time to time deem
advisable. If any assets are to be distributed in kind, such assets shall be
distributed on the basis of their fair market value as determined pursuant to
Section 11.4 hereof; provided, however, that if a Limited Partner notifies the
Partnership in writing that the receipt by such Limited Partner of a
distribution of assets would result in a material violation of ERISA by such
Limited Partner, then the General Partner shall use reasonable efforts to
arrange for the sale of such assets on behalf of and for the account of such
Limited Partner and shall follow such procedures described in Section 8.6.3
hereof as it deems necessary or appropriate under the circumstances including,
without limitation, treatment of such assets as

                                      -11-
<PAGE>

"Designated Securities," as defined in Section 8.6.3 hereof.

          5.2.2(a) Distributions of cash or Securities will initially be made
     pro rata to the Partners in an amount equal to the income from Liquid
     Investments that has been credited to their Capital Accounts pursuant to
     4.2(c) from the inception of the Partnership less any prior distributions
     pursuant to this Section 5.2.2(a).

               (b) Except as provided in paragraph (c) or (d) below, all other
     distributions of cash or Securities will be made as follows:  (i) a
     fraction of each distribution equal to the fraction derived by dividing the
     aggregate Capital Contributions of the Class A Limited Partners by the
     aggregate Capital Contributions of all Limited Partners shall be made 95%
     to the Class A Limited Partners pro rata according to the ratio that each
     such Class A Limited Partner's respective Capital Contribution bears to all
     the Capital Contributions of all Class A Limited Partners and 5% to the
     General Partner; and (ii) a fraction of each distribution equal to the
     fraction derived by dividing the aggregate Capital Contributions of the
     Class B Limited Partners by the aggregate Capital Contributions of all
     Limited Partners shall be made 80% to the Class B Limited Partners pro rata
     according to the ratio that each such Class B Limited Partner's respective
     Capital Contributions bears to all the Capital Contributions of all Class B
     Limited Partners and 20% to the General Partner.

               (c) In no event may the amount distributed to the General Partner
     pursuant to Section 5.2.2(b)(i) or (ii) exceed the General Partner's
     Capital Account resulting from Section 4.2(d)(i) or 4.2(d)(ii) as adjusted
     by Sections 4.2(e) and (g), respectively. Any remaining amount
     distributable pursuant to either Section 5.2.2(b)(i) or (ii) shall be
     distributable only among the Limited Partners otherwise entitled to
     distributions pursuant to either (i) or (ii).

               (d) Notwithstanding the aforementioned distributions, the General
     Partner, in its sole discretion, may elect to distribute cash or Securities
     to the Limited Partners in excess of the amount otherwise required pursuant
     to Sections 5.2.2(b) and (c).

     5.3    Intent of Distribution Provisions.  The intent of the distribution
provisions is to distribute over the life of the Partnership (i) income from
Liquid Investments to the Partners based on their Capital Accounts as of the
beginning of the Accounting Period during which such income is earned, (ii)
original Partnership capital contributed by the Limited Partners back to the
Limited Partners to the extent of their contributions, (iii) net Partnership
profits attributable to the Class A Limited Partners' capital 95% to the Class A
Limited Partners and 5% to the General Partner, and (iv) net Partnership profits
attributable to Class B Limited Partners' capital 80% to the Class B Limited
Partners and 20% to the General Partner.  The distribution provisions shall be
interpreted by the General Partner, in its sole discretion, to achieve these
objectives.  Notwithstanding any other provision of this Agreement, the General
Partner may amend or modify the provisions of Articles IV or V hereof without
the consent of the Limited Partners to the extent that the General Partner, in
its sole discretion, deems such amendment or modification reasonably necessary
to cause all distributions or allocations to be made according to the foregoing
intent.

     5.4    Distributions Upon Liquidation.

          5.4.1  To effect the dissolution and liquidation of the Partnership
pursuant to Section

                                      -12-
<PAGE>

10.1 hereof, the General Partner, in accordance with the provisions of Section
5.4.2 below, shall distribute all assets of the Partnership to the Partners in
cash or ratably in kind. Distribution of assets in kind shall be made in
accordance with their fair market value as determined pursuant to Section 11.4
hereof.

          5.4.2  The net proceeds resulting from the liquidation of the
Partnership pursuant to a dissolution of the Partnership shall be distributed
and applied in the following order of priority:

               (a) to the payment of the expenses of liquidation and the debts
     and liabilities of the Partnership, including the Management Fee;

               (b) to the setting up of any reserves that the General Partner
     determines are reasonably necessary for any contingent or unforeseen
     liabilities or obligations of the Partnership (which shall be distributed
     in accordance with (c) below if and when the General Partner determines in
     its sole discretion that such reserves are no longer required); and

               (c) to and among the Partners in proportion to their respective
     positive Capital Account balances (after making the adjustments required by
     Section 4.2 hereof with respect to any assets to be distributed in kind).


                                   ARTICLE VI
                                   Management

     6.1    Management of Partnership.

          6.1.1  The management and control of the business and affairs of the
Partnership shall be vested solely in the General Partner; provided that the
General Partner shall make investment decisions for the Partnership only after
obtaining the approval of the Advisory Board, as provided in Section 9.4 below.

          6.1.2  The General Partner shall manage the business and affairs of
the Partnership so that the assets of the Partnership, in the General Partner's
reasonable determination, will not be considered plan assets within the meaning
of ERISA; provided, however, if the General Partner determines in the reasonable
exercise of its judgment that continuing to manage the business and affairs of
the Partnership in such a manner is not in the best interests of the Partners as
a whole, it may cease managing the business and affairs of the Partnership in
such a manner, so long as it notifies each Limited Partner at least sixty (60)
days in advance of its intent to cease managing the Partnership in such a
manner, and each Limited Partner which provides the General Partner with an
opinion of counsel reasonably satisfactory to the General Partner consistent
with Section 8.6.2 shall be allowed to withdraw from the Partnership pursuant to
Sections 8.6.2 and 8.6.3 hereof.

     6.2    Authority of General Partner.

          6.2.1  Subject to the terms and provisions of this Agreement, the

     expenses of the members of the Advisory Board in attending Advisory Board
     meetings as provided in Section 9.4 hereof;

               (c) to engage such agents, attorneys, accountants, custodians and
     financial advisors and consultants as are necessary or advisable for the

     instruments and evidences of indebtedness, and to secure the payment
     thereof by mortgage, pledge or assignment of or security interest in all or
     any part of the

                                      -14-

     property then owned or thereafter acquired by the Partnership, including
     from any Partner or any of their affiliates;

               (k) to enter into, make and perform such contracts, agreements
     and other undertakings, and to do such other acts as are necessary or
     advisable for, or as may be incidental to, the conduct of the business of
     the Partnership, including, without in any manner limiting the generality

     Partnership; provided, that no compensation shall be paid by the
     Partnership to any party for services rendered in connection with the
     placement of Limited Partner interests in the Partnership.

     6.3    Limitation on Authority of General Partner.  The General Partner,
without the prior written consent or ratification of all Partners, shall have no
authority to:

               (a) do any act which would contravene this Agreement; or

               (b) admit a Person as a General Partner of the Partnership.

     6.4    Partnership Contracts.  All contracts undertaken by the Partnership
shall be executed by the General Partner and in such contracts the Partnership
shall be identified as a limited partnership.  The Partners shall promptly
execute (with acknowledgment, if required) at the request of the General
Partner, any and all instruments necessary or appropriate to ratify or confirm
the authority of the General Partner hereunder.

     6.5    Obligations of General Partner.

          6.5.1  The General Partner and the officers and employees thereof
shall devote such time and effort to the Partnership business as may be
necessary or appropriate to manage the affairs of the Partnership but shall not
be required to devote full time to the affairs of the Partnership.  For its
services to the Partnership, the General Partner shall be entitled to receive
the Management Fee provided for in Section 6.7 hereof and to be reimbursed for
any expenses enumerated in Section 6.2.2 hereof which it may have paid on behalf
of the Partnership.

          6.5.2  Without limiting the generality of the General Partner's
duties and obligations hereunder, and so long as the General Partner retains
control and responsibility for the management and

                                      -15-
<PAGE>

investment decisions of the Partnership, and subject to the limitations set
forth in Section 6.3, the General Partner, either itself or through contracts
with other parties, shall:

               (a) provide office space for the Partnership;

               (b) provide staff for the analysis of, investment in, and
     divestment from investment opportunities;

               (c) maintain the books and records of the Partnership, make
     annual progress and portfolio reports to the Limited Partners, upon request
     of a Limited Partner, furnish such Limited Partner with copies of the

     amendments to Schedule 1 hereto; and

               (d) generally provide all overhead and required support for the
     Partnership not identified in this Agreement as an obligation and expense
     of the Partnership.

          Except to the extent specifically provided for in Section 6.2.2
hereof, the General Partner shall cause payment to be made for all normal
operating expenses of the Partnership related to personnel, including salaries,
rent, communication and entertainment, out of the Management Fee provided for in
Section 6.7 hereof.

          6.5.3  In the event that both Andrew J. Filipowski and Steven D.
Devick are no longer providing services to the Partnership (in their capacities
as directors, officers, employees or agents of the General Partner), the General
Partner shall convene a meeting of the Advisory Board.  The General Partner,
with the assistance of the Advisory Board, shall develop within ninety (90) days
a business plan with respect to the future management of the Partnership for
approval by Limited Partners which have a majority of the total Limited Partner
Interests.  If a business plan is not approved within six (6) months, then
Limited Partners holding a majority of the total Limited Partner Interests may
vote to dissolve the Partnership.  Once such plan is approved, the General
Partner shall operate the Partnership's business in accordance with the approved
plan.  Until the plan is approved, the General Partner shall continue to operate
the Partnership in accordance with past practice to the extent reasonably
possible.

     6.6    Liability of General Partner.  The General Partner will not be
liable to any Limited Partner or the Partnership for any act or omission taken
or omitted as General Partner with respect to the Partnership which is not in
violation of the provisions of this Agreement, or for any act or omission taken
or omitted by any shareholder, director, officer, affiliate, employee or agent
of the General Partner, except in the case of the General Partner's (or such
other person's) own willful, wanton or intentional misconduct, malfeasance or
gross negligence.

     6.7    Management Fee.

          6.7.1  The Partnership shall pay to the General Partner in cash
during the period from the First Closing through the sixth anniversary thereof,
as payment for services rendered as General Partner, for facilities supplied
hereunder and as full reimbursement for all expenses set forth in Section 6.5.2
hereof, compensation (the "Management Fee") at an annual rate equal to two and
one-half percent (2.5%) (adjusted as described in Section 6.7.6) of the total
Committed Capital of all Partners, as set forth

                                      -16-
<PAGE>

in Schedule 1 hereto, as of the first day of the calendar year for which the
Management Fee is due. The Management Fee shall be paid on the first day of each
calendar quarter in advance for such quarter.

          6.7.2  For the period beginning on the day after the sixth
anniversary of the First Closing and ending with the termination of the
Partnership,  the Management Fee shall equal two and one-half percent (2.5%)
(adjusted as described in Section 6.7.6) of the Estimated Value of the Fund as
of the first day of the calendar year for which the Management Fee is due.

          6.7.3  Notwithstanding Section 6.7.1 above, for the first twelve
calendar months after the First Closing, including the month in which the First
Closing occurs (the "First Year"), the Management Fee shall be payable as
follows:

               (a) A portion of such Management Fee shall be paid to the General
     Partner at the First Closing, which portion shall be determined based upon
     total Committed Capital of all Partners as of the First Closing and shall
     be prorated according to the number of days remaining in the calendar
     quarter in which the First Closing occurs, including the day of the First
     Closing.

               (b) The next portion shall be payable at the earlier of the date
     of the next Subsequent Closing or the first day of the calendar quarter in
     the First Year succeeding the quarter in which the First Closing occurs.
     The amount payable on the first day of such succeeding calendar quarter and
     any calendar quarters remaining in the First Year shall be based upon total
     Committed Capital as set forth on Schedule 1 as of such date. At each
     Subsequent Closing, the Management Fee for the First Year shall be
     recalculated to take into account additional amounts of Committed Capital
     stated on Schedule 1 hereto as of such Subsequent Closing as if such amount
     of total Committed Capital existed on the date of the First Closing. The
     additional amount which would have been paid if such additional amount of
     Committed Capital had been included on Schedule 1 hereto as of the First
     Closing and on the first day of any calendar quarter preceding the
     Subsequent Closing on which a portion of the Management Fee was paid shall
     be paid to the General Partner at the Subsequent Closing.

          6.7.4  The Management Fee payable to the General Partner shall not be
considered a distribution of profits or return of capital to the General
Partner for the purpose of any provision of this Agreement, but shall be
considered a deduction from Partnership income or increase in Partnership losses
in determining Net Income or Net Losses, or items of income or expense, pursuant
to Article IV hereof.  If there is a final determination that any fee payable to
the General Partner under this Section 6.7 is not deductible by the Partnership
for federal income tax purposes, the gross income for such year or subsequent
years, as necessary, shall be specially allocated to the General Partner until
the gross income so allocated equals the total amount of such Management Fee
determined not to be deductible.  If such special allocation to the General
Partner affects the allocations to the Limited Partners otherwise determined
under Article IV hereof, the allocations to all Partners shall be adjusted
proportionately.

          6.7.5  The Management Fee payable for any quarter shall be increased
(or decreased) by the percentage increase (or decrease) in the Consumer Price
Index for All Urban Consumers, U.S. City Average, for all items, during the
immediately preceding calendar year, or if the U.S. government ceases to publish
such index, then by such index published by the U.S. government as is in the
General Partner's judgment most similar to such index; provided that in no event
shall any decreases in such index

                                      -17-
<PAGE>

result in the amount of the Management Fee being less than its initial level;
and provided further that in no event shall the Management Fee be increased by
more than 10% in any calendar year pursuant to this Section 6.7.5.

     6.8    Other Services.  In addition to the items provided by the General
Partner or its affiliates and described in Section 6.5.2, and subject to the
limitations of Section 6.3, the General Partner or its affiliates may also
provide to the Partnership certain of the services (e.g., accounting) identified
in Section 6.2.2 and may charge the Partnership therefor, provided that the
General Partner in its sole discretion believes that it or its affiliates can
provide such services at no greater cost than would be the case if unaffiliated
third parties were to provide such services.  The General Partner or its
affiliates may receive consulting and investment banking fees from portfolio
companies, including, without limitation, underwriting fees, merger and
acquisition advisory fees, and placement fees.  The General Partner and its
affiliates or employees may also receive fees for serving as directors or other
officials of portfolio companies.  The Management Fee shall be reduced by the
amount of any director's fees or consulting fees paid by any portfolio company
to the General Partner or any employee or affiliate of the General Partner other
than any Managing Directors who are not also shareholders of the General
Partner.  The Management Fee shall not be reduced by the amount of any
investment banking fees received by the General Partner or any employee or
affiliate of the General Partner from a portfolio company so long as such
investment banking fees were determined through arms'-length negotiation with an
independent representative(s) of the portfolio company.

                   Rights and Obligations of Limited Partners

     7.1    Limitations on Limited Partners.  The Limited Partners shall take no
part in the management or control of the Partnership business, and have no right

matters set forth in this Agreement or in the Act.

     7.2    Removal of General Partner.

          7.2.1  The General Partner may be removed as General Partner for
cause upon the written request of those Limited Partners which have at least
two-thirds (2/3) of the total Limited Partner Interests.  Such written request
shall be delivered to the General Partner and shall state the cause for removal
and the effective date of such action, which effective date may be immediately
upon delivery of the notice or thereafter.  "Cause" for the removal of the
General Partner shall mean the commission of more than one act of gross
negligence, material deviation from the stated investment strategy of the
Partnership (as provided in Section 2.7 hereof) without the consent of Limited
Partners which have at least two-thirds (2/3) of the total Limited Partner
Interests, fraud, willful, wanton or intentional misconduct or malfeasance
which, in each case, materially and adversely affects the Partnership.

          7.2.2  If the General Partner is removed pursuant to this Section 7.2,
and the Partnership is continued, the General Partner shall become a Limited
Partner in all respects under the Act as of the date of its removal, and its
interest in the Net Income and Net Losses, and items of income and expense of
the Partnership, shall convert, as of the date of its removal, into a Limited
Partner interest and the General Partner's share of the most recent Estimated
Value of the Fund shall be treated as Committed

                                      -18-
<PAGE>

Capital for purposes of determining the Limited Partner Interest attributable to
the converted interest. The General Partner shall be entitled to all of the
rights of the other Limited Partners with respect to its converted interest,
including the right to receive allocations and distributions on the basis of the
Committed Capital that results from the conversion of its interest.

          7.2.3  Except as otherwise required by law, if the General Partner is
removed pursuant to this Section 7.2, it shall not be liable for any obligations
of the Partnership arising after the effective date of its removal. The
Partnership shall, within fifteen (15) days after the removal of the General
Partner, file an amendment to the Certificate to reflect the removal of the
General Partner as general partner.

          7.2.4  In the event of the removal of the General Partner, the
Limited Partners may elect a new General Partner to continue the business of the
Partnership in accordance with the requirements of the Act.  If a new General
Partner is not elected within ninety (90) days after removal of the previous
General Partner, the Partnership shall be dissolved, wound up and terminated.

     7.3    Restructuring of General Partner.  Any change in the ownership of a
majority or more of the outstanding voting equity interests in the General
Partner shall require the written consent of Limited Partners which have at
least two-thirds (2/3) of the Limited Partner Interests.

     7.4    Deficit Capital Accounts at Liquidation.  No Limited Partner shall
have any obligation upon termination of the Partnership to restore a negative
Capital Account balance other than to contribute any amounts required to be
contributed pursuant to Section 3.3 hereof.


                                  ARTICLE VIII
                     Assignability of Interest; Withdrawal

     8.1    Assignment of General Partner's Interest.  The General Partner shall
not transfer its interest in the Partnership as General Partner or voluntarily
withdraw as General Partner without the written consent of Limited Partners
which have at least two- thirds (2/3) of the Limited Partner Interests.
Notwithstanding the foregoing, the General Partner or the partners thereof may
assign a portion of the right to receive Partnership distributions to other
Persons.

     8.2    Assignment of Limited Partner's Interest.  A Limited Partner may not
sell, transfer, assign, pledge, subdivide for resale or otherwise dispose of all
or any part of its interest in the Partnership (whether voluntarily,
involuntarily or by operation of law) without the prior written consent of the
General Partner, the granting or denying of which shall be in the General
Partner's absolute discretion.  No assignee of a Limited Partner shall become a
Substitute Limited Partner in the place of its assignor except as provided in
Section 8.3 hereof.  The Partnership shall have no obligation to recognize,
furnish information or make distributions to any assignee of a Limited Partner
which does not become a Substitute Limited Partner, and such assignee's rights
shall be only against its assignor.

     8.3    Substitute Limited Partner.  No assignee of the whole or any part of
a Limited Partner Interest shall be substituted as a Limited Partner without the
prior written consent of the General Partner, the granting or denying of which
consent shall be in the General Partner's absolute discretion.  As a

                                      -19-
<PAGE>

condition to the approval or consent of the General Partner to the admission of
an assignee of a Limited Partner as a Substitute Limited Partner, the General
Partner:

          8.3.1  shall require such assignee to accept and assume, in form
satisfactory to the General Partner, all the terms and provisions of this
Agreement, and

          8.3.2  may require such assignee to:

               (a) provide an opinion of counsel, in form and substance
     reasonably satisfactory to counsel for the Partnership, that assignment of
     the Limited Partner Interest and substitution of the assignee as a Limited
     Partner does not result in termination of the Partnership for purposes of
     Section 708 or any successor or similar provision of the Code;

               (b) provide an opinion of counsel, in form and substance
     reasonably satisfactory to counsel for the Partnership, that neither the
     offering nor the assignment of the Limited Partner Interest violates any
     registration provision of any federal or state securities or comparable
     laws, subjects the Partnership to registration as an investment company
     under the Investment Company Act of 1940, as amended, or requires that the
     General Partner or the Partnership register as an investment adviser under
     the Investment Advisers Act of 1940, as amended;

               (c) provide an opinion of counsel, in form and substance
     reasonably satisfactory to counsel for the Partnership, that assignment of
     the Limited Partner Interest and substitution of the assignee as a Limited
     Partner will not cause the Partnership to be classified as an association
     taxable as a corporation or to be treated as a publicly traded partnership
     as defined in Sections 7704(b) and 469(k)(2) of the Code;

               (d) execute such other documents or instruments as the General
     Partner may reasonably require to effect the admission of such assignee as
     a Limited Partner; and

               (e) pay such reasonable expenses as the Partnership may incur in
     connection with such substitution.

     8.4    Effective Date.  The effective date of a substitution shall be the
date designated by the General Partner in writing to the Substitute Limited
Partner, which shall not be later than the first day of the calendar quarter of
the Partnership next following the date upon which the General Partner has given
its written consent to such substitution.

     8.5    Amendment of Agreement.  This Agreement shall be amended, if and
when appropriate, to reflect the substitution or addition of Limited Partners.

     8.6    Withdrawal by Limited Partner.

          8.6.1  A Limited Partner may not withdraw from the Partnership
unless the General Partner shall have previously consented in writing to such
withdrawal, the granting or denying of which consent shall be in the General
Partner's absolute discretion.  A Limited Partner shall be allowed to

                                      -20-
<PAGE>

withdraw as herein provided only upon written notice requesting such withdrawal.

          8.6.2  Notwithstanding Section 8.6.1 above and in addition to the
right of a Limited Partner not to pay a portion of such Limited Partner's
Committed Capital under certain circumstances pursuant to Section 3.2.2 above,
if any Limited Partner provides the General Partner with an opinion of counsel
satisfactory to the General Partner that in such counsel's reasonable opinion,
(a) ERISA, the Bank Holding Company Act of 1956, as amended, or any similar
legislation, or any federal or state legislation applicable to governmental
pension plans, or regulations thereunder, shall require such Limited Partner
(hereinafter sometimes referred to as a "Regulated Limited Partner") to divest
its interest in the Partnership prior to dissolution of the Partnership, (b)
such Limited Partner's continued investment in the Partnership is contrary to
such laws or regulations, (c) the assets of the Partnership may be deemed to
constitute the assets of such Limited Partner under ERISA, or (d) the trustees
or other fiduciaries of such Limited Partner may be deemed under ERISA to have
delegated investment discretion over plan assets (as defined by ERISA) to any
Person that is not an investment manager (as defined by ERISA), the General
Partner shall use reasonable efforts to seek a buyer or buyers (which may be
other Limited Partners) for the remainder of the interest held by such Limited
Partner or shall seek to make such changes in the Partnership or its operation
so as to comply with such laws or regulations; provided, however, the General
Partner shall not make any changes which it determines not to be in the best
interests of the Partnership or a majority in interest of the Limited Partners,
or if the General Partner determines that changes are not necessary in order to
comply with such laws or regulations.  If no buyer is found for all of such
Limited Partner's interest in the Partnership and changes, if any, made by the
General Partner are not reasonably satisfactory to such Limited Partner, upon
request of such Limited Partner, the General Partner shall consent to the
withdrawal of such Limited Partner from the Partnership pursuant to this Section
8.6.

          8.6.3  In the event a Limited Partner withdraws from the Partnership
pursuant to this Section 8.6, the Partnership shall pay such withdrawing Limited
Partner an amount equal to such Limited Partner's share of the Estimated Value
of the Fund most recently determined pursuant to Section 11.4 hereof. Such
amount shall be paid without interest within a reasonable period of time, and in
the case of a withdrawal pursuant to Section 8.6.2 hereof, within 120 days of
the Partnership's receipt of the opinion of counsel described therein; provided,
however, it shall not be paid during a time that such payment would impair the
Partnership's ability to make the distributions targeted pursuant to Section 5.1
hereof or would cause hardship to the Partnership. The General Partner shall
have absolute discretion to make the distribution in respect of the interest of
a withdrawing Limited Partner in cash or in kind; provided, however, that if the
withdrawing Limited Partner notifies the Partnership in writing that the receipt
by such Limited Partner of a distribution of Securities in kind would result in
a material violation of ERISA by such Limited Partner, then the General Partner
shall use reasonable efforts to arrange for the sale of such Securities on
behalf of and for the account of such Limited Partner. At the discretion of the
General Partner, a Partner withdrawing from the Partnership pursuant to this
Section 8.6 may be charged an amount, not exceeding 2% of the amount payable to
the Partner for such withdrawal, as the General Partner determines is reasonable
to defray the expenses of the Partnership in connection with such withdrawal.
Any portion of distributions made to a withdrawing Limited Partner in kind
pursuant to this Section 8.6 shall be made in proportion to such Limited
Partner's percentage interest in each Security then held by the Partnership;
provided, however, that the General Partner may withhold from distribution any
Securities the distribution of which would, in the General Partner's sole
discretion, cause hardship to the issuer or to the Partnership. If distribution
is to be made in kind and if such distribution cannot be made

                                      -21-
<PAGE>

in full because of restrictions on the transfer of Securities or for any other
reason, such distribution may be delayed until an effective transfer and
distribution may be made, and Securities for transfer in respect of the
withdrawing Limited Partner's interest shall be designated by the General
Partner (the "Designated Securities"). Such Designated Securities may
nevertheless be sold by the General Partner, provided that the General Partner
remit the cash proceeds therefrom to the withdrawing Limited Partner. The
withdrawing Limited Partner shall not share in the income and losses of the
Partnership from the date of its withdrawal and shall have no further interest
in the Partnership or its assets, except that it shall receive income and
dividends paid by the issuer with respect to any Designated Securities and shall
be entitled to the appreciation of or suffer the depreciation of such Designated
Securities and shall be specially allocated an appropriate amount of the Net
Income or Net Losses resulting from the sale by the Partnership of Designated
Securities on its behalf. Schedule 1 hereto shall be revised to reflect such
withdrawal and the withdrawing Limited Partner shall no longer be considered a
Limited Partner for purposes of this Agreement.

          8.6.4  No distribution shall be made to a withdrawing Limited
Partner unless all liabilities of the Partnership have been paid or unless the
Partnership has assets sufficient to pay such liabilities.  No Limited Partner
shall have the right to demand or receive property other than cash in return for
its Partnership interest, and no Limited Partner, upon withdrawal, shall have
priority over any other Limited Partner as to either a return of its Capital
Contribution or distribution of its share of Partnership profits.

     8.7    Required Withdrawal.  Notwithstanding anything contained herein to
the contrary, the General Partner may, at any time and without prior notice,
require any Limited Partner which in its sole determination it deems to be a
Regulated Limited Partner, to withdraw entirely from the Partnership, or to
withdraw a portion of its Capital Account as necessary in order for the assets
of the Partnership not to be treated as Plan Assets under ERISA.  The Limited
Partner thus designated shall be deemed to have withdrawn from the Partnership
or to have made a partial withdrawal from its Capital Account, as the case may
be, without further action on the part of the Limited Partner.

     8.8    Partners Meetings.  Once each year, upon at least thirty (30) days'
prior written notice, the General Partner shall conduct a meeting open to all
Partners.  At the meeting, the General Partner will discuss the status of any
prospects for the Partnership and its portfolio companies.  The Partners
understand and acknowledge that such meeting may occur in conjunction with an
investment conference sponsored by one or more of the principals of the General
Partner, but will be conducted separately from the main investment conference.


                                   ARTICLE IX
                                  Investments

     9.1    Liquid Investments.  To the extent that the Partnership from time to
time has funds which are not invested in private debt or  equity investments
pursuant to this Agreement, the Partnership shall invest in highly liquid
investments ("Liquid Investments") providing for appropriate safety of
principal, such as commercial paper bearing the highest rating of a nationally
recognized rating agency, money market mutual funds, securities issued by the
United States Government, any instrumentality thereof, or one of the states of
the United States, or a domestic bank with total assets in excess of
$5,000,000,000, to

                                      -22-
<PAGE>

provide liquid investments from which to meet obligations of the Partnership and
to hold funds pending investment or distribution.

     9.2    Policy With Respect to Investment Opportunities.

          9.2.1  Each Partner agrees that any other Partner and its respective
partners, officers, directors and affiliates may acquire an interest in any
business or investment venture in which the Partnership has an interest and may
engage in or possess an interest in other business or investment ventures of
every kind and description, independently or with others, and provide services
to such ventures, including but not limited to serving as their officers,
directors, partners, trustees, advisers, employees or agents. Neither the
Partnership nor the Partners shall have any rights in or to such permitted
activities of any Partner or any compensation or profits derived therefrom.

          9.2.2  Each Partner recognizes that decisions concerning investments
and potential investments involve the exercise of judgment and the risk of loss
and the General Partner may elect to refer investment opportunities which come
to its attention to one or more Partners, any partner, employee, officer,
director or affiliate of a Partner, or any other Person. The General Partner, in
the reasonable exercise of its judgment, may cause the Partnership to exercise
an investment opportunity only in part based on factors such as diversification
among companies and/or types of investments and the amount of Partnership funds
available for investment. Each Partner further understands and acknowledges that
the General Partner and its affiliates do or may serve as general partners or
otherwise make investment decisions on behalf of other businesses, ventures and
investment partnerships, that such businesses, ventures and partnerships do and
will have uninvested funds, and that the General Partner or such affiliates will
refer investment opportunities to such businesses, ventures and partnerships
that might otherwise be referred to the Partnership. If the General Partner
determines, in the reasonable exercise of its judgment, that it is not in the
best interests of the Partnership to invest in a particular private equity
investment, the General Partner shall not be required to cause the Partnership
or allow any Partner to invest in any such investment, and may refer the
investment opportunity to investors other than the Partnership; provided,
however, that if the General Partner or any of its principals elects to invest
in such private equity investment, the General Partner shall give notice thereof
to the Advisory Board. The General Partner also reserves the right, in its sole
and absolute discretion, to permit another investment entity for which the
General Partner or affiliate thereof acts as investment manager to invest in an
investment opportunity along with the Partnership, or to refer an investment
opportunity to such other entity. Any participation allocated to the Partnership
in any investment in which the General Partner or any one or more of the General
Partner's respective shareholders, officers, directors, employees or affiliates
participates shall be on terms no less favorable to the Partnership than the
terms of investment by any of such persons, provided that such investments occur
at substantially the same time. The General Partner, its directors, officers,
employees and Persons related to or affiliated with the General Partner shall
not accept any finder's fee or similar payment in connection with any investment
made by the Partnership.

     9.3    Investment Intent of Limited Partners.  Each Limited Partner by
execution of this Agreement warrants to every other Partner and to the
Partnership that such Limited Partner is acquiring its interest in the
Partnership for purposes of investment only, for its own account (or where
applicable in its fiduciary capacity) and not with the view to resell or to
distribute the same or any part thereof, and that no other person has any
interest in such Partnership interest or in the rights of such Limited Partner
hereunder other than as a shareholder in such Limited Partner in the case of a
corporate Limited Partner,

                                      -23-
<PAGE>

partner in a partnership Limited Partner, in which case the names of and all
requested information concerning all such partners have been disclosed to the
General Partner, or as a participant or beneficiary of an employee benefit plan,
trust or other entity with respect to which such Limited Partner is acting in a
fiduciary capacity.

     9.4    Advisory Board.

          9.4.1  The Advisory Board shall consist of at least five (5) but no
more than fifteen (15) representatives selected from among the Class A Limited
Partners by the General Partner for one-year terms. The Advisory Board shall
meet no less frequently than once every year as scheduled by the General
Partner.

          9.4.2  As soon as reasonably practicable after the General Partner has
completed its due diligence investigation regarding a potential investment in a
portfolio company and has preliminarily decided to make such investment on
behalf of the Partnership, the General Partner shall review the material terms
and conditions of such contemplated investment with the Advisory Board. The
Advisory Board shall then have no less than seven (7) days to make its
recommendations to the General Partner regarding the contemplated investment. If
the General Partner and the Advisory Board are unable to agree on the terms of
the Partnership's investment in the portfolio company, then the General Partner
shall be prohibited from making such investment on behalf of the Partnership.

          9.4.3  The Advisory Board also shall review the valuation of the
Partnership's assets as determined by the General Partner pursuant to Section
11.4 hereof, and consult with and advise the General Partner upon such matters
and at such times as requested by the General Partner; provided, however, the
General Partner shall not be bound by the advice of the Advisory Board (except
as specified in Section 9.4.2).

          9.4.4  A majority of the entire Advisory Board shall constitute a
quorum for purposes of meetings of the Advisory Board.  Any recommendation,
determination or action authorized at a meeting of a quorum by at least a
majority of all members then present shall constitute action by the Advisory
Board.  Any recommendation, determination or action authorized by action in
writing by a majority of all members of the Advisory Board also shall constitute
action by the Advisory Board.

          9.4.5  Members of the Advisory Board shall not be compensated for
serving as members of the Advisory Board but shall be reimbursed for the
reasonable expenses of attending Advisory Board meetings.

     periods upon the prior written approval of Limited Partners which have more
     than two-thirds (2/3) of all Limited Partner Interests.

          10.1.2  Dissolution of the Partnership shall be effective on the date
on which the event occurs giving rise to the dissolution, but the Partnership
shall not terminate until the Certificate shall have been canceled 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

the Partnership shall be made pursuant to Section 5.4 hereof.

     10.3   Election to Carry on Business.  Upon the occurrence of an event
described in Section 10.1(b) hereof, the Limited Partners may, within ninety
(90) days of such event, elect to carry on the business of the Partnership with
one or more substitute General Partners by the affirmative vote of Limited
Partners required by the Act.  If such an election is made, the General Partner
shall receive in cash within ninety (90) days after such election the value of
its interest in the Partnership as of the date of such election.


                                   ARTICLE XI
                        Books, Records and Bank Accounts

     11.1   Books and Records.  The General Partner shall keep accurate books of
account with respect to the operations of the Partnership.  Such books shall be
maintained at the principal place of business of the Partnership, or at such
other place as the General Partner shall determine, and all Partners, and their
duly authorized representatives, shall at all reasonable times have access to
such books and the right to make copies thereof.

                                      -25-
<PAGE>

     11.2   Accounting Basis and Accounting Year.  Such books shall be kept on
an accrual basis in accordance with the accounting methods followed by the
Partnership for federal income tax purposes and otherwise in accordance with
generally accepted accounting principles applied in a consistent manner, reflect
all Partnership transactions, be appropriate and adequate for the Partnership's
business and for the carrying out of all provisions of this Agreement, and be
closed and balanced at the end of each calendar year.

     11.3   Reports.  As promptly as possible after the close of each calendar
year, the General Partner shall cause an examination of the financial statements
of the Partnership as of the end of such year to be made in accordance with
generally accepted auditing standards as in effect on the date thereof by a firm
of certified public accountants of national standing that the General Partner
shall employ at the Partnership's expense.  As soon as is practicable
thereafter, a copy of such financial statements prepared in accordance with
generally accepted accounting principles, including the report of such certified
public accountants, shall be furnished to each Partner and shall include, as of
the end such year:  a statement of the assets and liabilities of the
Partnership; a statement of operations setting forth the net losses or net
income of the Partnership; and a statement of changes in the Partnership's net
assets.  The General Partner shall cause such certified public accountants to
supply in a timely manner all other information necessary to enable each Partner
to prepare its income tax return, and the General Partner shall supply such
other information as each Partner may reasonably request for the purpose of
enabling it to comply with any reporting requirements imposed by any
governmental agency or authority.

     11.4   Valuation of Partnership Assets.

          11.4.1  The General Partner shall value the Partnership assets as of
the last day of each calendar quarter of each year and shall, within ninety (90)
days thereafter, furnish to each Limited Partner a statement showing the cost
and estimated value of each asset, the net worth of the Partnership (the
"Estimated Value of the Fund") and the balance of such Partner's Capital Account
and such Partner's share of the Estimated Value of the Fund as determined
pursuant to Section 11.4.3 below. In addition, the General Partner shall value
any Securities which are to be distributed in kind pursuant to Article V or
Section 8.6.3 hereof as of the date of such distribution and shall provide
Limited Partners with a summary statement showing the cost and estimated value
of such Securities.

          11.4.2  In determining the value of Partnership assets, no value shall
be placed on the goodwill or the name of the Partnership, or the office records,
files, statistical data or any similar intangible assets of the Partnership not
normally reflected in the Partnership's accounting records, but there shall be
taken into consideration any related items of income earned but not received,
expenses incurred but not yet paid, liabilities fixed or contingent, prepaid
expenses to the extent not otherwise reflected in the books of account, and the
value of options or commitments to purchase Securities pursuant to agreements
entered into on or prior to such date of valuation. Determinations of value of
Securities made pursuant to this Section 11.4 shall be based on all relevant
factors, including, without limitation, type, marketability, restrictions on
disposition, subsequent purchases of the same or similar Securities by other
investors, pending mergers or acquisitions, and current financial position and
operating results; provided, however, the value of a Security which is listed on
a recognized securities exchange or traded pursuant to the National Association
of Securities Dealers Automated Quotation System shall be valued at its most
recent sale price and the value of a Security which is otherwise traded in the
over-the-counter

                                      -26-
<PAGE>

market shall be valued at its most recent bid price discounted, in both
instances, to reflect any restrictions on transfer. The value of each
Partnership asset and the Estimated Value of the Fund determined by the General
Partner pursuant to this Section 11.4 and reviewed by the Advisory Board shall
be conclusive and binding on all of the Partners and all parties claiming
through or under them.

          11.4.3  Each Partner's share of the Estimated Value of the Fund shall
be the amount such Partner would receive on liquidation of the Partnership
under Section 5.4.2.

     11.5   Depository Accounts.  The General Partner shall be responsible for
causing one or more accounts to be maintained in one or more banks or other
depositories, which accounts shall be used for the payment of expenditures
incurred by the General Partner in connection with the business of the
Partnership, and in which shall be deposited any and all cash receipts.  All
such amounts shall be and remain the property of the Partnership, and shall be
received, held and disbursed by the General Partner for the purposes specified
in this Agreement.  There shall not be deposited in any of such accounts any
funds other than funds belonging to the Partnership, and no other funds shall in
any way be commingled with such funds.

     11.6   Tax Elections.

          11.6.1  The General Partner, in its sole discretion, may make or
revoke an election to adjust the basis of the assets of the Partnership for
federal income tax purposes in accordance with Section 754 of the Code, in the
event of a distribution of Partnership property as described in Section 734 of

     12.3   Partner Duties.  Pursuant to Section 1101(d) of the Act, the duties
of the Partners to the other Partners and to the Partnership are hereby limited
to those provided expressly herein.

     12.4   Indemnification of General Partner.  The General Partner, its
directors, officers, shareholders, employees, affiliates and agents, shall be
indemnified to the fullest extent permitted by law by the Partnership against
any cost, expense (including attorneys' fees), judgment and/or liability
reasonably incurred by or imposed upon the General Partner or such other persons
in connection with any action, suit or proceeding (including any proceeding
before any administrative or legislative body or agency) to which the General
Partner or such other persons may be made a party or otherwise involved or with
which the General Partner or such other persons shall be threatened by reason of
being or having been, or acting on behalf of, the General Partner; provided,
however, that the General Partner or such other persons shall not be so
indemnified with respect to any matter as to which the General Partner or such
other persons shall not have acted in good faith in what the General Partner or
such other persons reasonably believed was in, or not opposed to, the best
interests of the Partnership.  The General Partner or such other persons shall
be entitled to indemnification pursuant to this Section 12.4, only to the extent
that the General Partner or such other persons does not have the right to and in
fact does not recover amounts with respect to the claim upon which the demand
for indemnification is based from third parties whether due to indemnification
by such third parties, insurance or otherwise, provided, that the amount the
General Partner or such other persons is entitled to recover from the
Partnership pursuant to indemnification hereunder shall include all expenses,
including reasonable attorneys' fees, of collecting such amounts from such third
parties.  The right of indemnification granted by this Section 12.4 shall be in
addition to any rights to which the General Partner or such other persons may
otherwise be entitled and shall inure to the benefit of the successors, assigns,
executors or administrators of the General Partner or such other persons.  The
Partnership shall pay the expenses incurred by the General Partner or such other
persons in defending an action, suit or proceeding in advance of the final
disposition of such action, suit or proceeding, upon receipt of an undertaking
by or on behalf of the General Partner or such other persons to repay such
amount if there shall be an adjudication or determination that it is not
entitled to indemnification as provided herein.  The right of indemnity or
reimbursement granted in this Section 12.4 may not be satisfied except out of
the assets of the Partnership, and no Partner shall be personally liable with
respect to any such claim for indemnity or reimbursement.

     12.5   Partition.  The Partners hereby agree that no Partner or any
successor-in-interest to any Partner shall have the right while this Agreement
remains in effect 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 behalf of itself, and its
successors, representatives 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 its
interest in the Partnership or any of its assets shall be subject to the
limitations and restrictions of this Agreement.

     12.6   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

                                      -28-

the same or any other obligation.

     12.7   Amendment of Agreement.  This Agreement shall be amended only upon
the written agreement of the General Partner and Limited Partners which hold at
least two-thirds (2/3) of total Limited Partner Interests; provided, however,
that no amendment shall be made to Sections 3.2.2, 6.1.2, 8.6.2 or 8.6.3 of this
Agreement without the prior written agreement of Limited Partners holding not
less than two-thirds (2/3) of the Limited Partner Interests held by Limited
Partners that are subject to ERISA.  The General Partner may, in its discretion,
require an opinion of counsel reasonably satisfactory to the General Partner
that a Limited Partner which so represents in fact is subject to ERISA.
Notwithstanding anything contained herein to the contrary, the General Partner
may amend this Agreement without the consent of the Limited Partners to the
extent necessary to satisfy any regulatory requirements of any Regulated Limited
Partners or prospective Regulated Limited Partners.

     12.8   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 provisions hereof.

     12.9   Counterparts.  This Agreement may be executed in any number of
counterparts, all of which together shall for all purposes constitute one
Agreement, binding on all Partners, notwithstanding that all Partners have not
signed the same counterpart.  A Limited Partner may evidence his agreement to be
bound hereby by execution of a subscription agreement for Limited Partner
Interests or another appropriate writing without the necessity of executing a
counterpart hereof.

     12.10   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 Delaware (regardless of the choice of
law principles of Delaware or of any other jurisdiction).

     12.11   Gender and Number.  Wherever from the context it appears
appropriate, each term stated in either the singular or the plural shall include
the singular and the plural, and pronouns stated in either the masculine, the
feminine or the neuter gender shall include the masculine, feminine and neuter.

     12.12   No Third Party Beneficiaries.  This Agreement is for the sole
benefit of the parties hereto, and no third party shall be a beneficiary of the
Partners' obligations hereunder including, without limitation, their obligations
to contribute capital to the Partnership.

     12.13   Severability.  If it is determined by a court of competent
jurisdiction that any provision of this Agreement is invalid under applicable
law, the remainder of this Agreement, or the application of such provision to
persons or circumstances other than those to which it is held invalid, shall not
be affected thereby.

     12.14   Entire Agreement.  This document, together with each Limited
Partner's subscription agreement for Limited Partner Interests, contains the
entire Agreement among the parties and supersedes all prior arrangements or
understandings with respect thereto.
