                   CAPITAL CONTRIBUTIONS; PARTNERS' ACCOUNTS
                   -----------------------------------------

     Section 3.1  Capital Commitments and Contributions.
                  -------------------------------------

     Subject to the provisions of Sections 3.3 and 3.5, each Partner intends to
make cash contributions to the capital of the Partnership in the amount set
forth opposite its name on Schedule 1 attached hereto.  The amount of such
                           ----------
commitment, reduced by any portion of the commitment which is released pursuant
to Section 3.5 and increased or decreased by any amount pursuant to Section 3.6,
is referred to herein as a "Capital Commitment."  With respect to each Partner,
the amount of capital contributed pursuant to such Capital Commitment and, after
the end of the Commitment Period, amounts proportional to the Partner's
Percentage of Contributed Capital that are reserved from Operating Receipts or
Investment Receipts and invested in Follow-on Investments or Committed
Investments, are referred to as "Capital Contributions."  On any date when a
Limited Partner makes a Capital Contribution to the Partnership, the General
Partner shall contribute to the capital of the Partnership cash in such amount
as is sufficient to cause the General Partner's Capital Contribution to equal
one percent (1%) of the aggregate Capital Contributions of all Partners.  The
General Partner shall call for payment of the balance of each Partner's Capital
Commitment as needed to fund the Partnership's investments in Portfolio
Companies and other permitted uses under this Agreement in accordance with this
Article III; provided, however, that no call may be made at any time subsequent
to the Commitment Period except to the extent necessary to (i) provide for the
expenses of the Partnership including the Management Fee, (ii) make Committed
Investments pursuant to Section 6.2.M or (iii) make Follow-on Investments
pursuant to Section 6.2.L; and provided further, however, that mandatory capital
contributions by the Limited Partners shall be required only for (x) funding the
payment of Partnership expenses in accordance with Section 6.5 (but not
including indemnification expenses pursuant to Section 9.3), and (y) the
Management Fee. All such calls shall be made in writing to all Partners pro rata
in proportion to their respective Capital Commitments and shall specify the
intended use of such called capital, including in the case of a capital call to
invest in a Portfolio Company the name of the Portfolio Company. Such calls
shall be made at least ten (10) Business Days before the date on which the
installment payable in response to that call is due. The Capital Contributions
of a Partner shall not in any case exceed the Capital Commitment of such Partner
except as such Partner may otherwise consent. No Capital Contribution returned
to a Partner, other than a Capital Contribution that is allocable to a Temporary
Bridge Financing which has been sold, refinanced or otherwise disposed of, shall
be callable by the General Partner pursuant to this Section 3.1 again, except as
such Partner may otherwise consent.

     Section 3.2  Initial Capital Contribution of the Limited Partners.
                  ----------------------------------------------------

     Upon formation of the Partnership, each Limited Partner shall pay a capital
contribution (such Limited Partner's "Initial Contribution" and such date of
payment being the "Initial Contribution Date") to the Partnership, by wire
transfer or check, in an amount equal to such

                                      -14-


Limited Partner's pro rata share (based upon Capital Commitments of the Limited
Partners) of the initial Management Fee, calculated from March 8, 2000 of the
Domestic Fund. In addition, each Limited Partner shall contribute capital to the
Partnership in an amount equal to (i) such Limited Partner's pro rata share
(based upon Capital Commitments of the Limited Partners) of the product of the
Aggregate Partnership Percentage (as defined below) as of the time of such
Initial Contribution multiplied by the aggregate original purchase price of the
securities held by the Domestic Fund in which the Partnership determines to
invest (as set forth below), plus (ii) interest calculated in the same manner as
in Section 8.2 of this Agreement (as to additional Limited Partners), plus (iii)
such Limited Partner's pro rata share (based upon Capital Commitments of the
Limited Partners) of the organizational fees and expenses payable in accordance
with Section 6.5. The General Partner and the Limited Partners shall follow the
procedures set forth in Section 3.3 with respect to the securities held by the
Domestic Fund on the date of formation of the Partnership in order to determine
the securities in which the Partnership will invest and for which Partners will
contribute capital. The Limited Partners shall fund the capital contribution
described in this Section 3.2 within ten (10) business days of the date that the
General Partner gives the Limited Partners written notice confirming the amount
of such capital contribution. The General Partner shall cause the Domestic Fund
to transfer the securities so acquired by the Partnership as soon as reasonably
practicable following such capital contribution, such transfer to be effected in
a manner reasonably satisfactory to the Limited Partners and their counsel. For
purposes of this Article III, "Aggregate Partnership Percentage" equals the
quotient, expressed as a percentage, of the aggregate Capital Commitments of all
of the Partners of the Partnership, divided by the sum of the aggregate Capital
Commitments of all of the Partners of the Partnership plus the aggregate capital
commitments of all of the partners of the Domestic Fund.

     Section 3.3  Other Capital Contributions by the Limited Partners.
                  ---------------------------------------------------

     Capital contributions by the Limited Partners to fund investments of the
Partnership shall be made from time to time in accordance with this Section 3.3.

     (a)  The General Partner shall offer to the Partnership the opportunity to
acquire its Aggregate Partnership Percentage of each investment opportunity
offered to the Domestic Fund, including any Follow-on Investments, on the same
terms and conditions as those offered to the Domestic Fund. In the event that a
Majority in Interest of the Limited Partners of the Partnership desires to fund
an investment, then each Limited Partner of the Partnership (including those who
have not so notified the General Partner) shall be required to contribute
capital to the Partnership in an amount equal to that portion of the investment
which equals the product of (x) the quotient obtained by dividing its Capital
Commitment by the Capital Commitments of all of the Partners times (y) the
Partnership's aggregate investment amount ("Pro Rata Share"). The Partnership
shall not make any investments in securities (other than Temporary Investments)
without the prior written approval of a Majority in Interest of the Limited
Partners of the Partnership as set forth in this Section 3.3. The General
Partner's obligations under this Section 3.3 shall commence on the date hereof
and shall continue throughout the term of the Partnership.

                                      -15-


     (b)  In connection with a proposed investment to be made by the
Partnership, the General Partner shall give each Limited Partner a written
investment memorandum (an "Investment Memo") summarizing such investment, and
indicating the date on which a definitive decision shall be required by a
Majority in Interest of the Limited Partners of the Partnership (the "Decision
Date"), which shall be no less than 30 days from the date of delivery of the
Investment Memo or Follow-On Investment Memo (as defined below), as the case may
be, except in unusual or exigent circumstances where the requirements of the
particular transaction dictate a shorter notice period, which circumstances
shall be described in writing in the Investment Memo. The Investment Memo shall
include (a) the name of the company in which such investment may be made, (b) a
description of the business engaged in by such company, (c) the background and
suitability of the portfolio company's senior management, (d) historical
financial data for such company, if available, (e) financial forecasts, (f) the
rationale for such investment, (g) the projected internal rate of return for
such investment based on forecasted revenue, operating margins and net income
and valuation multiples of revenue and net profit, (h) valuations, valuation
multiples and operating results of comparable companies selected by the General
Partner, (i) the proposed amount and terms of the proposed investment by the
Domestic Fund and the Partnership, (j) the proposed use of proceeds by such
company, (k) the projected future financing requirements of such company, (l) a
description of such company's products and technology including an assessment of
its advantages, (m) a description of such company's market, including estimates
of the size of the current and future market, (n) descriptions of current and
anticipated competitive companies and technologies, (o) risks and other issues
of the investment, (p) the General Partner's expected action plan or agenda
relating to the investment, (q) a capitalization table, reflecting the ownership
of management and other investors and stock option plan(s), (r) a description of
(A) any interest in such company that is held by the General Partner or its
Affiliates, and (B) any other affiliations known to the General Partner between
such company and the General Partner, any Affiliate of the General Partner or
any portfolio company in which one of the persons listed in the preceding clause
(A) has made an investment, and (s) any other information reasonably requested
by the Limited Partners.

     (c)  Prior to the closing of any investment to be made by the Domestic Fund
in a Follow-on Investment, the General Partner shall deliver to each Limited
Partner a written recommendation memorandum (a "Follow-On Investment Memo")
summarizing such Follow-on Investment, and indicating the Decision Date
therefor. Such Follow-on Investment Memo shall include (a) the name of the
portfolio company, (b) the most recent financial data for the company, (c) the
rationale for the Follow-on Investment, (d) the amount and terms of the proposed
Follow-on Investment, (e) an update to the other information provided pursuant
to subparagraph (ii), and (f) any other information reasonably requested by the
Limited Partners.

     (d)  Within three (3) business days of receipt of the Investment Memo or
Follow-on Investment Memo, each Limited Partner shall notify the General Partner
as to whether such Limited Partner will be able to reach a decision as to such
investment on or before the Decision Date.

                                      -16-


     (e)  On or before the Decision Date, each Limited Partner shall notify the
General Partner as to whether or not such Limited Partner will participate in
such investment. If a Majority in Interest of the Limited Partners of the
Partnership fails to provide to the General Partner an affirmative notice
pursuant to this clause on or before the Decision Date, such failure shall be
regarded as a waiver by all Limited Partners of their right to participate in
such investment.

     (f)  Any capital contribution agreed to be made by the Limited Partners
pursuant to this Section 3.3 shall be made by check or wire transfer upon no
less than ten (10) business days' prior written notice given by the General
Partner.

     (g)  Notwithstanding the above, with respect to the following Follow-on
Investments, if (i) the initial Investment Memo provides the Limited Partners
with the same type of information for any proposed Follow-On Investments as
required in Investment Memos and Follow-On Investment Memos, plus information
indicating the milestones and other goals for such portfolio company and a price
range for the subsequent securities and market capitalization range for such
portfolio company at the time of the Follow-On Investment, and (ii) the Limited
Partners agree to fund the initial investment in such portfolio company based
upon the comprehensive initial Investment Memo, and (iii) the General Partner
provides the Limited Partners with a memorandum stating that such portfolio
company has met such milestones and goals (or other equivalent progress) and the
price of the securities in the Follow-On Investment and market capitalization of
the portfolio company meet the ranges specified in the initial Investment Memo,
then the Limited Partners Partners shall be required to fund such Follow-On
Investment up to the amount specified in the initial Investment Memo.

     Section 3.4  Capital Accounts.
                  ----------------

     The Partnership shall establish and maintain a Capital Account for each
Partner. A Partner's Capital Account shall be (i) increased by (a) the amount of
such Partner's Capital Contributions, (b) such Partner's allocations of
Operating Income and Investment Gain pursuant to Sections 5.7.A and 5.7.B, and
(c) items of income or gain specially allocated to such Partner pursuant to
Section 5.8 or 5.9, (ii) decreased by (x) the amount of money and the fair
market value of any property distributed to such Partner by the Partnership, (y)
such Partner's allocations of Operating Loss and Investment Loss pursuant to
Sections 5.7.A and 5.7.C and (z) items of loss, deduction or expenditure
specially allocated to such Partner pursuant to Section 5.8 or 5.9, and (iii)
adjusted to reflect any liabilities that are assumed by such Partner or the
Partnership or that are secured by property contributed by or distributed to
such Partner, all in accordance with Sections 1.704-1(b)(2)(iv) and 1.704-2 of
the Treasury Regulations. Except as otherwise provided in the Treasury
Regulations, a transferee of an interest in the Partnership shall succeed to the
Capital Account of its transferor to the extent allocable to the transferred
interest. Notwithstanding any provision of this Agreement other than Section
5.4, the General Partner shall revalue Partnership properties, and make
corresponding adjustments to the Partners' Capital Accounts, as prescribed by
Section 1.704-1(b)(2)(iv)(f) of the Treasury Regulations in connection

                                      -17-


with any contribution to or distribution by the Partnership of more than a de
                                                                           --
minimis amount of money or other property in exchange for an interest in the
- - -------
Partnership unless the General Partner reasonably determines that such
revaluations and adjustments are not necessary to reflect the economic interests
of the Partners in the Partnership. In addition, the book values of Partnership
properties shall be increased or decreased, as the case may be, to reflect any
adjustments to the adjusted tax bases of such properties pursuant to Section
734(b) or Section 743(b) of the Code to the extent that such basis adjustments
are taken into account in determining Capital Account balances pursuant to
Treasury Regulations Section 1.704-1(b)(2)(iv)(m) and have not been reflected in
adjustments to the book values of such properties pursuant to the preceding
sentence of this Section 3.4.

     Section 3.5  Review or Modification of Capital Commitments.
                  ---------------------------------------------

     Each Partner acknowledges that it is currently lawful for it to invest in
the Partnership.  Notwithstanding this acknowledgment and the provisions of this
Article III, no Partner shall be obligated to make any contribution of its
Capital Commitment if at the time such contribution is due (i) such Partner is
substantially likely to be prohibited from making investments in the Partnership
under any applicable federal or state law or regulations thereunder then in
effect, or (ii) if such Partner is a bank holding company, it has a significant,
pre-existing and continuing relationship with a Portfolio Company in which the
Partnership has proposed to invest (in each case, a "Modification Event"). In
the case of a Modification Event, the affected Partner shall advise the General
Partner of the specific terms of the Modification Event within five (5) Business
Days of receiving the call notice pursuant to Article III. The General Partner
shall promptly notify all other Partners of the alleged Modification Event.
Unless (x) in the case of a Modification Event set forth in clauses (i) or (ii)
above, the Partner asserting such Modification Event shall, at the request of
the General Partner, have delivered to the General Partner an opinion from
counsel reasonably satisfactory to the General Partner confirming the existence
of such Modification Event or (y) in the case of a Modification Event set forth
in clause (ii) above, the affected Partner shall have provided the General
Partner with such information and material, including, at the request of the
General Partner an opinion of counsel reasonably satisfactory to the General
Partner confirming, in the sole discretion of the General Partner, the existence
of this Modification Event, the General Partner may, as of the date on which the
contribution at issue was due and upon fifteen (15) days notice to the affected
Partner, reduce the Capital Account and percentage of Contributed Capital of
such Partner by one fourth and correspondingly increase the Capital Account and
Percentage of Contributed Capital of each other Partner in a manner similar to
that provided in Section 3.6.B; provided, that the Partner asserting the
prohibition shall not be deemed a Defaulting Partner, as defined in Section 3.6,
for purposes of the provisions thereof.

     Notwithstanding the provisions of this Agreement, the General Partner may
refuse to permit a Limited Partner to participate in an investment in a
Portfolio Company if, in the sole discretion of the General Partner, such
Limited Partner's participation would impair the ability of the Partnership or
the General Partner or make it impractical or inadvisable as a result of
regulatory or competitive considerations or otherwise to consummate or to
maintain the

                                      -18-


investment in the Portfolio Company. In this event, at the time of providing
call notices to the Limited Partners, the General Partner shall notify the
affected Limited Partner of its non-participation in the proposed investment and
give such Partner such information and material as the General Partner
determines is sufficient to warrant the non-participation of such Partner in the
investment. The decision of the General Partner to refuse a Limited Partner the
opportunity to participate in an investment shall be in the sole discretion of
the General Partner.

     Section 3.6  Default in Capital Commitment.
                  -----------------------------

     Except as provided in Section 3.5, in the event a Partner fails to fund its
Capital Commitment as required under Sections 3.1 to 3.3 in a timely manner, and
such failure continues for ten (10) Business Days after written notice of such
failure from the General Partner (or for such longer period (not to exceed
twenty (20) business days) as the General Partner may in its sole discretion
permit under extraordinary circumstances), then such Partner which failed to
make payment shall be a Defaulting Partner, and the following provisions of this
Section 3.6 shall apply:

     A.  Whenever the vote, consent or decision of the Partners is required or
permitted pursuant to this Agreement, any Defaulting Partner shall not be
entitled to participate in such vote or consent, or to make such decision, and
such vote, consent or decision shall be made as if such Defaulting Partner were
not a Partner.  Notwithstanding this prohibition, any such vote, consent or
decision shall be binding upon such Defaulting Partner.

     B.  The Defaulting Partner shall not be required to make any further
Capital Contributions to the Partnership and shall be released from that portion
of a Defaulting Partner's unfunded Capital Commitment (provided that such
Defaulting Partner shall remain fully liable to the creditors of the Partnership
to the extent of the installment of the Capital Commitment with respect to which
the default occurred).  Thereafter, the Defaulting Partner's Percentage of
Contributed Capital in all investments made by the Partnership in Portfolio
Companies after the date of default shall be zero, and the Percentages of
Contributed Capital of the remaining Partners shall be adjusted accordingly.

     C.  Except as set forth in this Section 3.6.C, the Defaulting Partner shall
not be entitled to receive any distribution of Operating Receipts or Investment
Receipts until the termination of the Partnership.  The General Partner shall
establish a separate escrow account with a Financial Institution into which will
be deposited all of the distributions of Operating Receipts and Investment
Receipts that the Defaulting Partner would otherwise be entitled to receive.
Upon the liquidation of the Partnership, the Defaulting Partner will be entitled
to receive from the separate escrow account, an amount equal to the lesser of
(i) seventy-five percent (75%) of the distributions it was otherwise entitled to
receive with respect to investments in Portfolio Companies that were consummated
prior to the date of the Defaulting Partner's default (without the addition of
interest that accrued on the amounts held in the separate escrow account) and
(ii) its aggregate Capital Contributions to the Partnership reduced by all
distributions made to the Defaulting Partner prior to the date of default.  Any
amounts remaining in the

                                      -19-


separate escrow account, including all interest earned on such amounts, shall
thereafter be distributed to the General Partner to compensate the General
Partner for any damages incurred as a result of the default and then to the non-
defaulting Limited Partners in proportion to their respective Percentages of
Contributed Capital recalculated as if the Defaulting Partner were not a Partner
of the Partnership. The Defaulting Partner shall be allocated Operating Income
and Loss and Investment Gain and Loss only with respect to investments in
Portfolio Companies that were consummated prior to the date of the Defaulting
Partner's default.

     D.   The provisions of Sections 3.6.B and C shall not apply more than once
to any Defaulting Partner.

     E.   No Defaulting Partner shall be entitled to assign its interest in the
Partnership in accordance with Section 8.3 without the consent of the General
Partner, which it may withhold in its sole discretion.

     F.   No right, power or remedy available to the General Partner in this
Section 3.6 shall be exclusive, and each such right, power or remedy shall be
cumulative and in addition to any other right, power or remedy available at law
or in equity. No course of dealing between the General Partner and any
Defaulting Partner, and no delay in exercising any right, power or remedy shall
operate as a waiver or otherwise prejudice the exercise of such right, power or
remedy.

     G.   Notwithstanding the remaining provisions of Section 3.6, this Section
3.6 shall only apply to a Partner's default relating to a mandatory capital
contribution and not a discretionary capital contribution under Section 3.3 and
the other provisions relating thereto.

                               BRIDGE FINANCING
                               ----------------

     Section 4.1  Extension of Bridge Financing.
                  -----------------------------

     Solely in order to facilitate the making of investments in Portfolio
Securities as expeditiously as practicable with the most favorable pricing
reasonably available, the Partnership may from time to time provide interim
financing ("Bridge Financing") to one or more Portfolio Companies until
permanent financing is arranged. All such Bridge Financing shall be designated
as such by the General Partner at the time it is first provided. All Bridge
Financing will be senior to the permanent investment of the Partnership in such
Portfolio Company, and bear interest or carry other compensation at rates not
less favorable to the Partnership than those available from an unaffiliated
Financial Institution. The General Partner will use its best efforts to cause
Bridge Financing to be converted into Portfolio Securities, and if not so
converted, to be sold or refinanced as promptly as practicable, and in any event
will use its best efforts to cause such conversion, sale or refinancing to occur
within one year after such Bridge Financing is first provided by the
Partnership. Bridge Financing may be provided to any single Portfolio Company
only to the extent that the sum of the Partnership's investment in such
Portfolio Company, including Portfolio Securities, Bridge Financings and the
amount of any guarantees, shall not exceed the lesser of (i) fifteen percent
(15%) of the Partnership's aggregate Capital Commitments, or (ii) the remaining
unfunded Commitments as of the date of such Bridge Financing.

     Section 4.2  Funding of Bridge Financing.
                  ---------------------------

     The Partnership may fund Bridge Financing by borrowing pursuant to Section
6.2.P from one or more Financial Institutions, by calling upon the Partners'
Capital Commitments in accordance with Section 3.2, or by guarantying
indebtedness incurred by the Portfolio Company with the written consent of Two-
Thirds in Interest of the Limited Partners of this Partnership, in each case
solely in order to facilitate the making of investments in Portfolio Securities
as expeditiously as practicable with the most favorable pricing reasonably
available.  The proceeds of the sale, refinancing or other disposition of
Temporary Bridge Financing which has been funded by the call of Capital
Commitments shall, to the extent of the Partners' Capital Contributions
allocable thereto, be returned to the Partners in proportion to such Partners'
Capital Contributions allocable to such investment within five (5) days after
the receipt thereof by the Partnership.  The Partners' Capital Commitments
remaining to be called shall thereafter include that portion of such allocable
Capital Contributions returned.

                                      -21-


     Section 4.3  Permanent Bridge Financing.
                  --------------------------

     If and to the extent that Temporary Bridge Financing is not converted into
Portfolio Securities or sold or refinanced within one year after it is provided,
it promptly shall be converted as of the end of such one year period into
financing ("Permanent Bridge Financing") on terms and in proportions not less
favorable to the Partnership, than those most recently offered by the
Partnership to prospective investors during the period that the financing
remained outstanding pursuant to Temporary Bridge Financing.  If the Temporary
Bridge Financing was funded through borrowings by a Portfolio Company guaranteed
by the Partnership, the Partnership, shall purchase its portion of the Permanent
Bridge Financing as if it were a permanent investment in a Portfolio Company.

                                      V.

              DISTRIBUTIONS; WITHHOLDING; VALUATION; ALLOCATIONS
              --------------------------------------------------

     Section 5.1  Withdrawal of Capital.
                  ---------------------

     No Partner shall have the right to withdraw capital from the Partnership
or, except as otherwise set forth in this Agreement and the Act, to receive any
distribution or return of its Capital Contribution.

     Section 5.2  Distributions Prior to Liquidation.
                  ----------------------------------

     A.   Subject to Sections 5.3 and 5.4, and except to the extent deemed
necessary by the General Partner to reserve for Committed Investments pursuant
to 6.2.M, Operating Receipts for each fiscal year (or fractional portion
thereof) shall be distributed to the Partners in proportion to their respective
Percentages of Contributed Capital.  Such distributions shall be made by the
General Partner within ninety (90) days after the close of each fiscal year and
at such other time or times as the General Partner shall determine.

     B.   Subject to Sections 5.3 and 5.4, and except to the extent deemed
necessary by the General Partner to reserve for Committed Investments pursuant
to 6.2.M, the General Partner shall, each calendar quarter on or before the
fifteenth day after the end of such quarter, make distributions of all
Investment Receipts and shall distribute such Investment Receipts as follows:

          (1) First, to the Partners in proportion to their Percentages of
              -----
     Contributed Capital, until such Partners have received from all
     distributions then or theretofore made pursuant to this Section 5.2.B(1),
     on a cumulative basis, an amount of distributions equal to the sum of (i)
     their Capital Contributions Allocable to Liquidated Portfolio Securities
     and (ii) all Management Fees that have been paid out of the Capital
     Contributions of the Limited Partners to the Management Company as of any
     date on which a distribution pursuant to this Section 5.2 will be made;

                                      -22-


          (2)  Second, twenty percent (20%) to the Partners in proportion to
               ------
     their Percentages of Contributed Capital and eighty percent (80%) to the
     General Partner until the General Partner has received pursuant to this
     Section 5.2.B(2) an amount of distributions equal to twenty percent (20%)
     of the amounts distributed to the Partners in proportion to their
     Percentages of Contributed Capital pursuant to (A) clause (i) of Section
     5.2.B(1), but only to the extent of the amount of Capital Contributions
     Allocable to Portfolio Securities attributable to expenses set forth in
     Sections 6.5.A(1) and (4) that have been allocated to a particular
     Portfolio Security and (B) clause (ii) of Section 5.2.B(1); and

          (3)  Third, thereafter, eighty percent (80%) to the Partners in
               -----
     proportion to their Percentages of Contributed Capital and twenty percent
     (20%) to the General Partner.

     For purposes of this Agreement, all amounts distributed to the General
Partner pursuant to Sections 5.2.B(2) and 5.2.B(3) (other than in proportion to
its Percentage of Contributed Capital) shall be referred to herein as "Incentive
Distributions."

     C.   In addition to any other obligations hereunder, the General Partner
shall endeavor (if practical and reasonable to do so in light of the
circumstances of the Partnership) to distribute, if available, sufficient
amounts of Operating Receipts and/or Investment Receipts to the Partners in
accordance with this Article V to enable them to make timely payment of any
Federal, state, local and foreign income tax liabilities incurred by them or
their principals as a result of their participation in the Partnership.

     D.   As of any date on which the General Partner determines to make a
distribution of Investment Receipts, the General Partner shall determine,
pursuant to Section 5.6, the fair market value of each investment in a Portfolio
Company which has not been sold or disposed of. The extent to which the
aggregate fair market values of all such investments are less than the aggregate
cost bases of all such investments for book purposes shall constitute a "Deemed
Portfolio Loss". That portion of each Liquidated Portfolio Security equal to the
amount of Deemed Portfolio Loss allocated with respect thereto shall, upon the
deemed or actual sale of that Liquidated Portfolio Security, be deemed to have
been sold for an amount equal to the amount of Deemed Portfolio Loss and shall
be deemed to have a tax basis of zero, and the tax basis of the remaining
portion of the Liquidated Portfolio Security shall include the amount of such
Deemed Portfolio Loss.

     E.   If upon the liquidation of the Partnership the General Partner shall
have received as Incentive Distributions under Section 5.2B(3) (that have not
been recontributed to the Partnership pursuant to Section 5.3) an aggregate
amount in excess of the amount the General Partner would have received as
Incentive Distributions pursuant to Section 5.2B(3), including liquidating
distributions, had the entire amount of Investment Receipts actually received by
the Partnership been received by the Partnership on the date of liquidation of
the Partnership, then the General

                                      -23-


Partner shall, to the extent of all distributions received as Incentive
Distributions pursuant to Section 5.2B(3) (that have not been recontributed to
the Partnership pursuant to Section 5.3), pay to the Partners in proportion to
their Percentages of Contributed Capital such excess.

     F.   The General Partner shall establish in its name, but for the benefit
of the Partners, a separate bank account at a Financial Institution (the "Escrow
Account"), in which it will maintain an amount equal to the lesser of (i)
twenty-five percent (25%) of all Incentive Distributions paid to the General
Partner, and (ii) the amount required to be added to the fair market value of
the existing Portfolio Securities of the Partnership, determined pursuant to
Section 5.6, so that the resulting total exceeds the total amount of Capital
Contributions allocable to such investments by twenty-five percent (25%). Upon
the liquidation of the Partnership, the General Partner shall distribute to the
Partners from the Escrow Account, in proportion to their Percentages of
Contributed Capital, that portion of the escrowed funds equal to the General
Partner's required payment under Section 5.2.E, or if such required payment is
in excess of such escrowed funds, the total amount held in such Escrow Account
plus an amount, paid directly by the General Partner, that when added to the
escrowed funds equals the General Partner's required payment pursuant to Section
5.2.E. Any funds held in the Escrow Account upon liquidation of the Partnership
and after the required payment pursuant to this Section and Section 5.2.E shall
be distributed immediately to the General Partner. The General Partner will
direct the investment of amounts held in the Escrow Account, which shall in any
event be made solely in investments qualifying as Temporary Investments. All
income earned on the amounts retained in the Escrow Account shall be distributed
at the end of each calendar quarter immediately to the General Partner.

     Section 5.3  Distributions Upon Liquidation.
                  ------------------------------

     Upon the liquidation of the Partnership, the assets of the Partnership
shall first be applied to the payment of, or the establishment of adequate
reserves or other provision for the payment of, the debts and obligations of the
Partnership. Thereafter, there shall be made a final allocation of Operating
Income or Loss and Investment Gain or Loss, as the case may be, and other items
to the Partners' Capital Accounts in accordance with Section 5.7. If the General
Partner has a negative balance in its Capital Account after such final
allocation, it shall contribute to the Partnership an amount of cash equal to
the excess of such negative balance over the amount that it is required to pay
to the Partners pursuant to Section 5.2.E. Notwithstanding the foregoing, the
General Partner's obligation to pay such excess pursuant to this Section 5.3
shall not inure to the benefit of, or be invoked or enforced by or for the
benefit of, any creditor who has otherwise contractually obligated itself to
look solely to all or a part of the assets of the Partnership and not to the
assets of any Partner for satisfaction of any debt owed or owing to that
creditor by the Partnership. The assets of the Partnership, including any
Portfolio Securities, whether or not such securities are Marketable Securities
(or the proceeds of sales or other dispositions in liquidation of assets of the
Partnership) remaining after the payment or other provision for the
Partnership's debts and obligations shall then be distributed to the Partners in
proportion to the positive balances in their Capital Accounts, determined after
the final allocation of Operating Income or Loss and Investment Gain or Loss,
and of other items to Capital Accounts has been made;

                                      -24-


provided that the name of the Partnership shall be transferred with a value of
$1.00 ascribed thereto, to the General Partner. For purposes of making this
distribution, such assets shall be valued pursuant to Section 5.6. Amounts
reserved or set aside, in connection with the Partnership's liquidation, for the
payment of Partnership debts and obligations, which are not utilized for such
payment, shall be distributed to the Partners in the same proportions that such
amounts would have been distributed hereunder if distributed upon the
Partnership's liquidation, as soon as practicable.

     Section 5.4  Distributions of Securities in Kind.
                  -----------------------------------

     A.   The General Partner shall distribute to the Partners as an Investment
Receipt any Portfolio Securities that become Marketable Securities promptly upon
their becoming Marketable Securities, when such a distribution would serve the
best interests of the Partnership. Factors to be considered by the General
Partner in making such a determination shall include (i) the fiduciary
obligations owed to the stockholders of the issuer of such Marketable Securities
by any Affiliate of the General Partner who may serve as a director of such
issuer, and (ii) whether retention of such Marketable Securities shall serve the
best interests of the Partnership by maintaining control of or influence over
the issuer of the securities, stabilizing the market for such securities until
such time as the securities are either distributed to the Partners pursuant to
this Section 5.4 or are sold or otherwise disposed of or facilitating subsequent
offerings by the issuer which shall include such Marketable Securities. The
General Partner shall notify the Limited Partners each time a Portfolio Security
becomes a Marketable Security. The General Partner shall not distribute
Portfolio Securities that are not Marketable Securities at any time other than
upon the liquidation of the Partnership.

     B.   With respect to securities distributed in kind to the Partners in
liquidation or otherwise, (i) any unrealized appreciation or unrealized
depreciation in the values of such securities shall be deemed to be realized by
the Partnership immediately prior to the liquidation or other distribution
event; and (ii) such appreciation or depreciation shall be allocated to the
Partners as part of the allocation of Investment Gain or Loss, as the case may
be, for the year of the distribution in accordance with Section 5.7 hereof, and
treating any property so distributed as a distribution of an amount in cash
equal to the fair market value of the property determined pursuant to Section
5.6. For the purposes of this Section 5.4.B, "unrealized appreciation" or
"unrealized depreciation" shall mean the difference between the fair market
value of such assets and the adjusted basis of such assets for federal income
tax purposes (or, in the case of any asset that is reflected on the books of the
Partnership at a value that is different from the Partnership's federal tax
basis in such asset in compliance with the Treasury Regulations, the value of
such asset as shown on the Partnership's books). This Section 5.4.B is merely
intended to provide a rule for allocating unrealized gains and losses upon
liquidation or other distribution event, and nothing contained in this Section
5.4.B or elsewhere in this Agreement is intended to treat or cause such
distributions to be treated as sales for value.

                                      -25-


     C.   If any Partner would otherwise receive a distribution of an amount of
any securities that would cause such Partner to own or control in excess of the
amount of such securities that it may lawfully own or control or which, by
reason of any legal or contractual restriction, the General Partner may not
distribute to such Partner, the Partner shall, solely for purposes of this
Agreement, be treated as if it had received such securities as a distribution in
kind pursuant to Section 5.4.B. The General Partner shall, at the written
request of such Partner and to the extent it is practicable to do so, dispose of
all or any portion of such securities on behalf of and as the agent for such
Partner and distribute the proceeds of such disposition to such Partner;
provided that such Partner shall bear all of the reasonable expenses (including,
without limitation, underwriting costs) of such disposition. In the alternative,
at the request of such Partner, the General Partner shall use reasonable efforts
to recapitalize the Portfolio Company so as to distribute to such Partner non-
voting securities. In either event, any discrepancy between the actual gain or
loss recognized upon the sale or other disposition of Portfolio Securities
(including Marketable Securities) and the unrealized appreciation or unrealized
depreciation in the values thereof as determined under Section 5.4.B, shall
constitute gain or loss of the Partner to whom the securities were
constructively distributed, and shall in no event constitute gain or loss to the
Partnership.

     D.   The General Partner may cause certificates evidencing any securities
to be distributed to be imprinted with legends as to such restrictions on
transfers that it may deem necessary, including legends as to applicable federal
or state securities laws or other legal or contractual restrictions, and may
require any Partner to which securities are to be distributed to agree in
writing that such securities will not be transferred except in compliance with
such restrictions and applicable law.

     Section 5.5  Withholding.
                  -----------

     Each Partner hereby authorizes the Partnership to withhold and to pay over
any withholding taxes payable by the Partnership, to the extent required by
applicable law, as a result of such Partner's status as a Partner hereunder. If
and to the extent that the Partnership shall be required under applicable law to
withhold any such taxes, such Partner shall be deemed for all purposes of this
Agreement to have received a payment from the Partnership as of the time such
withholding is required to be paid, which payment shall be deemed to be a
distribution to the extent that the Partner is then entitled to receive a
distribution. The amount of any distribution to which such Partner would
otherwise be entitled shall be reduced by the amount of such deemed
distribution. To the extent that the aggregate of such payments to a Partner for
any period exceeds the distributions to which such Partner is entitled for such
period, the amount of such excess shall be considered a loan from the
Partnership to such Partner, with interest at the Treasury Rate, until
discharged by such Partner by repayment, which may be made out of distributions
to which such Partner would otherwise be subsequently entitled. The withholdings
referred to in this Section 5.5 shall be made at the maximum statutory rate
applicable to such Partner under the applicable tax law unless the General
Partner shall have received either (i) an opinion of counsel, satisfactory to
the General Partner, to the effect that a lower rate is applicable,

                                      -26-


or that no withholding is applicable or (ii) any form authorized by the relevant
taxing authority signed by a Partner that establishes that no withholding is
required for such Partner. Notwithstanding the foregoing, the Partnership shall
not withhold any amount from distributions in any taxable year of the
Partnership with respect to a Limited Partner, provided that (i) such Limited
Partner delivers to the Partnership a properly executed withholding tax
exemption certificate in the form provided by the General Partner (or such form
as the Internal Revenue Service may require) for such year and (ii) there is no
charge in law regarding withholding obligations with respect to foreign persons
which, in the opinion of counsel to the Partnership, would require withholding
with respect to such Partner.

     Section 5.6  Valuation.
                  ---------

     For purposes of this Agreement except as specifically provided in Section
8.5, securities and other property of the Partnership shall be valued as
follows:

     A.   The Portfolio Securities of the Partnership shall be valued by the
General Partner pursuant to subparagraphs B, C, D and E hereof (i) at the time
of any distribution pursuant to Section 5.2 in order to determine the amount of
any Deemed Portfolio Loss, (ii) at the time of any distribution pursuant to
Section 5.4, (iii) upon the distribution of Partnership assets in liquidation
pursuant to Section 5.3 and (iv) annually pursuant to Section 10.3.

     B.   Marketable Securities shall (i) if traded on a national securities
exchange, be valued at the average of their last sales prices on such exchange
on which such Marketable Securities shall have traded on the last ten (10)
trading days on which such Marketable Securities were traded immediately
preceding the date of determination, or (ii) if the trading of such Marketable
Securities is reported through the National Association of Securities Dealers
Automated Quotation System, such Marketable Securities shall be valued at the
average of the last closing "bid" prices as shown by the National Association of
Securities Dealers Automated Quotation System on the last ten (10) trading days
on which such Marketable Securities were traded immediately preceding the date
of determination.

     C.   Except as provided in subparagraph E below, all property other than
Marketable Securities shall be valued by the General Partner in such manner as
it may determine in good faith.  Factors considered in valuing individual
securities will include purchase price, prices received in recent significant
private placements of securities of the same issuer, transfer restrictions on
the securities, prices of securities of comparable public and private companies
engaged in similar businesses and changes in the financial condition and
prospects of the issuer.

     D.   If, within thirty (30) days after receipt of notice of any valuation
made pursuant to subparagraph C above, Two-Thirds in Interest of the Limited
Partners shall so request, the General Partner shall obtain at the expense of
the Partnership a valuation of any securities or other property from an
independent firm of investment bankers of nationally recognized standing
selected by the General Partner and approved by Two-Thirds in Interest of the
Limited Partners,

                                      -27-


such approval not to be unreasonably withheld. The decision of such firm shall
be binding on all Partners. Each distribution in kind of securities other than
Marketable Securities subject to valuation under subparagraph B shall be
accompanied by a notice from the General Partner reminding the Limited Partners
of their right to require an independent valuation under this subparagraph D.

     E.   Upon liquidation of the Partnership, all assets which will be
distributed to the Partners in liquidation, other than Marketable Securities
subject to valuation under subparagraph B above, shall, upon request by Two-
Thirds in Interest of the Limited Partners, be valued by an independent firm of
investment bankers of nationally recognized standing selected by the General
Partner.  The decision of such firm as to the liquidation value of all such
assets shall be binding on all Partners.

     Section 5.7  Allocations of Operating Income and Loss and Investment Gain
                  ------------------------------------------------------------
and Loss.
- - --------

     A.   Subject to Sections 5.8 and 5.9, all Operating Income and Operating
Loss of the Partnership shall be allocated to the Partners in proportion to
their Percentages of Contributed Capital.

     B.   Subject to Sections 5.8 and 5.9, an Investment Gain for any fiscal
year or other accounting period of the Partnership shall be allocated as follows
and in the following order of priority as of the close of such fiscal year or
other accounting period:

          (1)  First, to the General Partner until there has been allocated on a
               -----
     cumulative basis pursuant to this Section 5.7.B(1) for all fiscal years and
     other accounting periods of the Partnership an amount of Investment Gain
     equal to the amount of Investment Loss that has been allocated pursuant to
     Section 5.7.C(3) for all fiscal years and other accounting periods of the
     Partnership;

          (2)  Second, to the Partners, in proportion to their Percentages of
               ------
     Contributed Capital, until there has been allocated on a cumulative basis
     pursuant to this Section 5.7.B(2) for all fiscal years and other accounting
     periods of the Partnership an amount of Investment Gain equal to the amount
     of Investment Loss that has been allocated pursuant to Section 5.7.C(2) for
     all fiscal years and other accounting periods of the Partnership;

          (3)  Third, to the Partners, in proportion to their Percentages of
               -----
     Contributed Capital, until there has been allocated on a cumulative basis
     for all fiscal years and other accounting periods of the Partnership
     pursuant to this Section 5.7.B(3), an amount of Net Investment Gain equal
     to the sum of (i) the amount of Deemed Portfolio Loss that has been
     included in the determination of Capital Contributions Allocable to
     Liquidated Portfolio Securities for purposes of making distributions
     pursuant to Section 5.2.B, and

                                      -28-


     (ii) the amount of distributions made with respect to Management Fees
     pursuant to clause (ii) of Section 5.2.B(1);

          (4)  Fourth, eighty percent (80%) to the General Partner and twenty
               ------
     percent (20%) to the Partners in proportion to their Percentages of
     Contributed Capital until the General Partner has been allocated on a
     cumulative basis for all fiscal years and other accounting periods of the
     Partnership pursuant to this Section 5.7.B(4), in addition to allocations
     made to the General Partner pursuant to this Section 5.7 in proportion to
     its Percentage of Contributed Capital, an amount of Net Investment Gain of
     the Partnership equal to the amount distributed to the General Partner
     pursuant to Section 5.2.B(2);

          (5)  Fifth, thereafter with respect to the remaining Net Investment

     Partner.

     C.   Subject to Sections 5.8 and 5.9, an Investment Loss for any fiscal
year or other accounting period of the Partnership shall be allocated as follows
and in the following order of priority as of the close of such fiscal year or
other accounting period:

          (1)  First, to the extent of the Net Investment Gain, if any, that has
               -----
     been allocated hereunder for all prior fiscal years and other accounting
     periods, to the Partners in proportion to the respective amounts, if any,
     by which (i) their allocations of Net Investment Gain for all such prior
     years and other periods exceed (ii) their Target Allocations as of the
     close of the fiscal year or other period for which an Investment Loss is
     then being allocated;

          (2)  Second, to the Partners, in proportion to their Percentages of
               ------
     Contributed Capital, until the Limited Partners' Capital Accounts have been
     reduced to zero; and

          (3)  Third, thereafter, to the General Partner.
               -----

     Section 5.8  Special Provisions.
                  ------------------

     The following provisions shall be complied with notwithstanding any
provision of this Agreement other than Section 5.9:

     A.   If any Partner unexpectedly receives any adjustment, allocation or
distribution described in Sections 1.704-1(b)(2) (ii)(d)(4), 1.704-
1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6) of the Treasury Regulations which
causes it to have an, or increases the amount of its, Adjusted Capital Account
Deficit, items of Partnership income and gain shall be specially allocated to
such Partner in an amount and manner sufficient to eliminate, to the extent
required by the Treasury Regulations, such Partner's Adjusted Capital Account
Deficit as quickly as possible, provided that an allocation pursuant to this
Section 5.8.A shall be made to a Partner only if and to the extent

                                      -29-


that such Partner would have an Adjusted Capital Account Deficit after all other
allocations provided for in this Article V have been tentatively made as if this
Section 5.8.A were not in this Agreement. This Section 5.8.A is intended to
constitute a "qualified income offset" as defined in Section 1.704-
1(b)(2)(ii)(d) of the Treasury Regulations.

     B.   Notwithstanding Section 5.7.C, an allocation of Operating Loss or
Investment Loss shall not be made to a Partner to the extent that such
allocation would cause such Partner to have an Adjusted Capital Account Deficit.
An allocation that would be made to a Partner but for this Section 5.8.B shall
instead be made to the other Partners to the extent, and in the proportions,
that they could then be made such allocation without causing them to have
Adjusted Capital Account Deficits. Any excess allocation of Operating Loss or
Investment Loss shall be made to the General Partner.

     C.   The allocations set forth in Sections 5.8.A, 5.8.B, and 5.9 hereof
(the "Regulatory Allocations") are intended to comply with certain provisions of
the Treasury Regulations. Notwithstanding any other provision of this Article V,
the Regulatory Allocations shall be taken into account in making allocations of
other items of income, gain, loss, deduction and expenditure among the Partners
so that, to the extent possible consistent with the Code and the Treasury
Regulations, and on a cumulative basis, the respective net amounts of such
allocations of other items and the Regulatory Allocations to the Partners are
equal to the respective net amounts that would have been allocated to the
Partners had no Regulatory Allocations been made. The General Partner shall
apply this Section 5.8.C at such times, in such order and in such manner as it
determines, in its sole discretion, is likely to minimize any economic
distortions caused by the Regulatory Allocations.

     D.   If contributions that would otherwise be required pursuant to Article
III with respect to the interest in the Partnership of a particular Limited
Partner are excused hereunder or by law, such interest shall be treated for
purposes of this Article V as an interest in a separate portfolio of assets in
which, subject to all other provisions of this Agreement, only such Limited
Partner (or his assignees or legatees) and the General Partner shall be entitled
to participate (as provided in this Article V). Such separate portfolio shall
consist of such Limited Partner's pro rata share (by allocable Capital
Contribution) of each Portfolio Security the Partnership's interest in which
was, or the assets of which were, acquired in part with capital contributions of
such Limited Partner. Such Limited Partner (and his assignees and legatees)
shall have no interest in the Partnership or its assets to the extent not
included in, and shall have no right to participate in the results of the
Partnership to the extent not attributable to, such separate portfolio. A
separate portfolio shall be charged with portions of the Partnership's expenses,
liabilities, costs and reserves in such manner as the General Partner reasonably
determines to be fair and equitable.

     E.   Income, gain, loss and deduction with respect to property contributed
to the Partnership by a Partner shall be shared among the Partners so as to take
account of the variation between the basis of the property to the Partnership
and its fair market value at the time of contribution in accordance with the
principles of Section 704(c) of the Code.

Regulations, it may have twenty percent (20%) to the General Partner and eighty
percent (80%) to the Partners in proportion to their Percentages of Contributed
Capital, (ii) shall allocate any "partner non-recourse deductions," computed and
determined in accordance with Sections 1.704-2(i)(1), 1.704-2(i)(2) and 1.704-
2(j) of the Treasury Regulations, it may have so as to comply with Section
1.704-2(i) of the Treasury Regulations and (iii) shall make such allocations as
are necessary to comply with the "minimum gain chargeback" provisions of
Sections 1.704-2(f), 1.704-2(i) and 1.704-2(j) of the Treasury Regulations,
taking into account all exceptions provided by such provisions to the
applicability of this clause (iii).

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

                                      VI.

Management Fee payable by Expansion LLC and the balance shall be credited

against the Management Fee payable by the Partnership, the Domestic Fund and
Expansion LLC in subsequent periods (in the same proportions). To the extent
such amounts exceed total future installments of the Management Fee, they shall
be paid to the Partnership, the Domestic Fund and Expansion LLC in the same
proportions and included in their respective Operating Receipts.

necessary to comply with applicable regulations or laws, or to address other
legal considerations, the General Partner shall not permit the Domestic Fund at

to the Partnership only with the written consent of, and on the terms approved
by, all Partners. Until such time, the General Partner may admit one or more
additional Limited Partners with the consent of a Majority in Interest of
Limited Partners of the Partnership, subject only to satisfaction of the
following conditions: (i) each such additional Limited Partner shall execute and
deliver a Subscription Agreement and an appropriate amendment to this Agreement
pursuant to which such additional Limited Partner agrees to be bound by the
terms and provisions hereof, (ii) such admission would not result in a violation
of any applicable law, including the federal or state securities laws, or any
term or condition of this Agreement and, as a result of such admission, the
Partnership would not be required to register as an investment company under the
Investment Company Act, and (iii) such additional Limited Partner shall pay to
the Partnership, on the date of its admission to the Partnership, an amount
equal to the sum of (x) the percentage of its Capital Commitment which is equal
to the percentage of the other Limited Partners' Capital Commitments that shall
have been payable at or prior to the admission of the additional Limited Partner
and (y) an amount equal to interest on that portion of the Capital Commitment
payable upon admission at the Treasury Rate from the date such portion would
have been payable if such additional Limited Partner had been admitted on the
date of formation of the Partnership to the date of actual payment, which amount
shall be treated as Operating Receipts. The Partnership shall pay, from such
initial Capital Contribution of such additional Limited Partner, its allocable
portion of the Management Fee computed as if such

                                      -40-


additional Limited Partner had been a Partner of the Partnership since the
Initial Closing Date. The name and business address of each Limited Partner
admitted to the Partnership under this Section 8.2 and the amount of its Capital
Commitment shall be added to Schedule 1 hereto. Each additional Limited Partner
                             ----------
admitted pursuant to this Section 8.2 during the 270 day period commencing with
the formation of the Partnership shall be deemed for purposes of all allocations
of Operating Income or Loss and Investment Gain or Loss to have been admitted on
the date of formation of the Partnership. Admission of an additional Limited
Partner shall not be a cause of dissolution of the Partnership.

     Section 8.3  Assignment of Partnership Interest.
                  ----------------------------------

     The General Partner shall not assign or otherwise transfer its interest as
the general partner of the Partnership. A Limited Partner may assign or
otherwise transfer all or any part of its interest in the Partnership (provided
that such part shall include a Capital Commitment, whether funded or unfunded,
of at least $1 million), subject to the limitations set forth in Section 8.4.
The assignee or transferee of a Limited Partner's interest in the Partnership
(an "Assignee") shall have the right to become a Substitute Limited Partner only
if the following conditions are satisfied:

     A.   A duly executed and acknowledged written instrument of assignment
shall have been filed with the Partnership.

     B.   The Limited Partner and the Assignee shall have executed and
acknowledged such other instruments and taken such other action as the General
Partner shall reasonably deem necessary or desirable to effect such
substitution, including, without limitation, the execution by the Assignee of a
Subscription Agreement, an appropriate amendment to this Agreement and a Power
of Attorney substantially similar to that referred to in Section 12.8 hereof.

     C.   The restrictions on transfer contained in Section 8.4 shall be
inapplicable, and, if requested by the General Partner, the Limited Partner or
the Assignee shall have obtained an opinion of counsel reasonably satisfactory
to the General Partner as to the legal matters set forth in that Section.   The
Limited Partner may request that the General Partner seek to obtain the required
opinion from counsel recommended by such Limited Partner which is reasonably
satisfactory to the General Partner, provided that the expense of such counsel
shall be an expense of the Partnership that is paid out of the Capital
Commitment of such Partner.

     D.   The Limited Partner or the Assignee shall have paid to the Partnership
such amount of money as is sufficient to cover all expenses incurred by or on
behalf of the Partnership in connection with such substitution.

     E.   The General Partner shall have consented, in its sole and absolute
discretion, to such substitution, except in the case of a transfer to an
Affiliate.

                                      -41-


     The pledge or hypothecation of a Partner's interest in the Partnership
shall not be deemed an assignment or transfer; provided, that such pledge or
hypothecation shall nonetheless be subject to the restrictions set forth in
Section 8.4.  An Assignee who is not admitted to the Partnership as a Substitute
Limited Partner shall have none of the rights of a Partner and the assignor in
such case shall remain fully liable for the unpaid portion of its Capital
Commitment.

     Section 8.4  Restrictions on Transfer.
                  ------------------------

     Notwithstanding any other provision of this Agreement, no Limited Partner
may assign or otherwise transfer all or any part of its interest in the
Partnership, and no attempted or purported assignment or transfer of such
interest shall be effective, unless (i) after giving effect thereto, such
assignment or transfer would not terminate the Partnership for the purposes of
Section 708 of the Code, (ii) such assignment or transfer would not result in a
violation of applicable law, including the federal and state securities laws, or
any term or condition of this Agreement and, as a result of such assignment or
transfer, the Partnership would not be required to register as an investment
company under the Investment Company Act, (iii) if requested by the General
Partner, such Limited Partner shall deliver a favorable opinion of counsel
satisfactory to the General Partner that such transfer would not result in (x) a
violation of the Securities Act or any blue sky laws or other securities laws of
any state of the United States applicable to the Partnership or the interest to
be transferred, (y) the Partnership being required to register, or seek an
exemption from registration, under the Investment Company Act, and (z) the
Partnership being deemed to be a "publicly traded partnership" within the
meaning of Section 7704 of the Code, (iv) except for an assignment to an
Affiliate of a Limited Partner, the General Partner shall have consented
thereto, which consent may be granted or withheld in its sole discretion, and
(v) such assignment or transfer is to an entity which is an Accredited Investor.

     Section 8.5  Removal of General Partner.
                  --------------------------

     A.   The General Partner may be removed by the Limited Partners only upon
the approval of at least Two-Thirds in Interest of the Limited Partners, (i) if
any act or omission of the General Partner in connection with the Partnership
constitutes bad faith, breach of fiduciary duty, willful misconduct or fraud,
(ii) if the General Partner is in material violation of its obligations
hereunder, or (iii) if a Triggering Event occurs; provided, however, that the
Limited Partners may remove the General Partner pursuant to clauses (i) and (ii)
above only if a court of competent jurisdiction or, at the election of Two-
Thirds in Interest of the Limited Partners, an arbitration committee (which
shall conduct its proceedings in accordance with the commercial rules of the
American Arbitration Committee and shall consist of three individuals, of whom
one shall be selected by the General Partner, one shall be selected by Two-
Thirds in Interest of the Limited Partners and one shall be selected by written
agreement of the other two) has previously determined that any act or omission
of the General Partner in connection with the Partnership constitutes bad faith,
willful misconduct or fraud or that the General Partner is in material violation
of its obligations hereunder.

                                      -42-


     B.   In the event of any such removal of the General Partner, the
Partnership shall, within sixty (60) days of the date of such removal, obtain an
appraisal of the Portfolio Securities of the Partnership, including Portfolio
Securities the purchase of which the Partnership has committed to as of such
removal date (together "Removal Date Securities") from an independent firm of
investment bankers of nationally recognized standing selected by the removed
General Partner and approved by Two-Thirds in Interest of the Limited Partners,
which approval shall not unreasonably be withheld. As of the removal date, the
removed General Partner shall become a Special Limited Partner. The Special
Limited Partner shall be entitled to receive as distributions pursuant to
Section 5.2 that portion of all distributions made with reference to its
Percentage of Contributed Capital, and that portion of all Incentive
Distributions it would have received pursuant to Section 5.2 with respect to the
Removal Date Securities, provided that all such distributions received in
connection with such Removal Date Securities do not in the aggregate exceed the
aggregate fair market value determinations for such securities made pursuant to
this Section 8.5.B. Notwithstanding the foregoing, if after the removal of the
General Partner the Partnership then terminates under Article XI without there
having been elected a successor General Partner, the General Partner shall be
entitled to the same allocations and distributions arising out of the
Dissolution Sale as if it had not been removed. The Special Limited Partner
shall not have the limited approval rights accorded to Limited Partners in this
Agreement, and as a Special Limited Partner, the General Partner and its
Affiliates shall be released from all commitments and obligations under Article
VII effective upon the date of such removal.

     Section 8.6  Withdrawals.
                  -----------

     No Partner shall have the right to withdraw from the Partnership, except in
connection with a transfer under Section 8.3.

                    LIABILITY OF PARTNERS; INDEMNIFICATION
                    --------------------------------------

     Section 9.1  Liability of General Partner.
                  ----------------------------

     A.   The General Partner shall be subject to the liabilities of a partner
in a partnership without limited partners, and nothing herein shall be deemed to
relieve the General Partner of liabilities to third parties which it otherwise
has under applicable law. The General Partner shall not be liable to the
Partnership or any other Partner for any act or omission taken or suffered by
the General Partner in good faith and in the belief that such act or omission is
in the best interests of the Partnership; provided that such act or omission is
not in violation of this Agreement and does not constitute willful misconduct,
fraud, recklessness, breach of fiduciary duty, gross negligence or a willful
violation of law by the General Partner.  The General Partner shall not be
liable to the Partnership or any other Partner for any action taken by any other
Partner, nor shall the General Partner (in the absence of willful misconduct,
fraud, recklessness, breach of fiduciary duty, gross negligence or a willful
violation of law by the General Partner) be liable to the

                                      -43-


Partnership or any other Partner for any action of any employee or agent of the
Partnership provided that the General Partner shall have exercised appropriate
care in the selection and supervision of such employee or agent.

     B.   Whenever in this Agreement the General Partner is permitted or
required to make a decision (i) in its "discretion" or "sole discretion" or
under a grant of similar authority or latitude, the General Partner shall be
entitled to consider only such interests and factors as it desires, including
its own interests, and shall have no duty or obligation to give any
consideration to any interests of or factors affecting any person other than the
Partnership, or (ii) in its "good faith" or under another express standard, the
General Partner shall act under such express standard and shall not be subject
to any other or different standard imposed by this Agreement or other applicable
law; provided that all judgments and determinations shall comply with the
fiduciary duty of the General Partner to the Limited Partners.

     C.   Notwithstanding Section 9.3 below, the General Partner shall not be
indemnified for any losses, liabilities or expenses arising from or out of an
alleged violation of federal or state securities laws unless (i) there has been
a successful adjudication on the merits of each count involving alleged
securities law violations as to the particular indemnitee, or (ii) such claims
have been dismissed with prejudice on the merits by a court of competent
jurisdiction as to the particular indemnitee, or (iii) a court of competent
jurisdiction approves a settlement of the claims against a particular
indemnitee. In any claim for indemnification for federal or state securities law
violations, the party seeking indemnification shall place before the court the
position of the Securities and Exchange Commission and the Massachusetts
Securities Division with respect to the issue of indemnification for securities
law violations. The Partnership shall not incur the cost of that portion of any
insurance, other than public liability insurance, which insures any party
against any liability the indemnification of which is herein prohibited.

     Section 9.2  Liability of Limited Partners.
                  -----------------------------

     Except as required by law, no Limited Partner shall be bound by, nor be
personally liable for, the expenses, liabilities, or obligations of the General
Partner or the Partnership.  Each Limited Partner shall be liable for the return
of any part of a distribution in respect of its Capital Contribution to the
extent required by law.

     Section 9.3  Indemnification of the General Partner and Limited Partners.
                  -----------------------------------------------------------

     The General Partner and its partners, agents, employees and Affiliates and
the Limited Partners (the "Indemnitees") shall be and hereby are (i) indemnified
and held harmless by the Partnership and (ii) released by the other Partners
from and against any and all claims, demands, liabilities, costs, expenses,
damages, losses, suits, proceedings and actions for which such Indemnitee has
not otherwise been reimbursed (collectively, "Liabilities"), whether judicial,
administrative, investigative or otherwise, of any nature whatsoever, known or
unknown, liquidated or unliquidated, that may accrue to the Partnership or any
other Partner or in which any

                                      -44-


of the Indemnitees may become involved, as a party or otherwise, arising out of
the conduct of the business or affairs of the Partnership by the respective
Indemnitee or otherwise relating to this Agreement, provided that an Indemnitee
shall not be entitled to indemnification or release hereunder if it shall have
been determined by a court of competent jurisdiction that (x) such person did
not act in good faith and in a manner such person reasonably believed to be in
the best interests of the Partnership and, in the case of a criminal proceeding,
did not have reasonable cause to believe that his conduct was lawful, or (y)
such Liabilities shall have arisen from a violation of this Agreement or the
gross negligence, willful misconduct, breach of fiduciary duty, fraud or willful
violation of law by such Indemnitee, or actions of such Indemnitee outside the
scope of and unauthorized by this Agreement. The termination of any proceeding
by settlement shall not, of itself, create a presumption that the Indemnitee did
not act in good faith and in a manner that such person reasonably believed to be
in the best interests of the Partnership or that the Indemnitee did not have
reasonable cause to believe that its conduct was lawful. Any indemnification
right provided for in this Section 9.3 shall be retained by any removed General
Partner and its partners, agents, employees and Affiliates. The indemnification
rights provided for in this Section 9.3 shall survive the termination of the
Partnership or this Agreement.

     Section 9.4  Payment of Expenses.
                  -------------------

     Expenses incurred by an Indemnitee in defense or settlement of any claim
that may be subject to a right of indemnification hereunder may be advanced by
the Partnership prior to the final disposition thereof provided that the
following conditions are satisfied: (i) the claim relates to the performance of
duties or services by the Indemnitee on behalf of the Partnership and (ii) the
Indemnitee undertakes to repay the advanced funds to the Partnership if it is
ultimately determined that the Indemnitee is not entitled to be indemnified
hereunder or under applicable law. The right of any Indemnitee to the
indemnification provided herein shall be cumulative of, and in addition to, any
and all rights to which such Indemnitee may otherwise be entitled by contract or
as a matter of law or equity and shall extend to such Indemnitee's successors,
assigns and legal representatives. All judgments against the Partnership and the
General Partner, in respect of which such General Partner is entitled to
indemnification, must first be satisfied from Partnership assets before the
General Partner is responsible therefor. The obligations of the Partnership
under this Article IX shall be satisfied only after any applicable insurance
proceeds have been exhausted and then only out of Partnership assets and, to the
extent required by law, distributions made by the Partnership to its Partners,
and Limited Partners shall have no personal liability to fund indemnification
payments hereunder.

distributed to a trust established for the benefit of the Partners for the sole
purposes of liquidating Partnership assets, collecting amounts owed to the
Partnership and paying any contingent or unforeseen liabilities or obligations
of the Partnership.  The distribution to the trust will constitute a final,
liquidating distribution of assets pursuant to Section 5.3.  The Partners'
beneficial interests in the trust will be equal to their respective interests in
the assets of the Partnership upon liquidation.  The trustee of the trust shall
be the General Partner or the liquidator.

assignments signed or purporting to be signed by the General Partner without
inquiry as to the authority of the person signing or purporting to sign such
instructions or assignments or as to the validity of any transfer to or from the
name of the Partnership. At the time of transfer, the corporation or transfer
agent is entitled to assume (i) that the Partnership is still in existence and

unless the corporation or transfer agent has received written notice to the
contrary.

     Section 12.3  Voting; Amendments.
                   ------------------

     On any occasion on which the General Partner submits to the Limited
Partners for their approval a proposed amendment, waiver or other action (a
"Vote") with respect to a provision of this Agreement (except as to Sections
3.1, 3.2, 4.2, 6.2C, 6.2D, 6.2K, 6.2N, 6.2P, and Sections 12.14 through 12.17,
and all provisions relating thereto, in which case the vote, consent or approval
of the Limited Partners of only this Partnership shall be obtained), and the
General Partner also submits to the Limited Partners of the Domestic Fund for
their approval a proposed Vote with respect to a provision with a substantially
similar impact of the partnership agreement for the Domestic Fund, then for
purposes of determining whether such Vote was approved by the Limited Partners,
(x) the Partnership will be deemed to have Capital Commitments equal to the
Capital Commitments of the Domestic Fund and the Capital Commitments of the
Partnership ("Deemed Total Capital Commitments"); (y) the portion of the Deemed
Total Capital Commitments attributable to the Domestic Fund shall be deemed
voted as actually voted by the Limited Partners of the Domestic Fund and (z) the
portion of the Deemed Total Capital Commitments attributable to the Partnership
shall be deemed voted as the Limited Partners actually vote. Subject to the
foregoing, this Agreement may be modified from time to time by the General
Partner and a Majority in Interest of the Limited Partners; provided that the

12.3; or (viii) amend, waive or remove any other right granted to the Limited
Partners of this Partnership not granted to the limited partners of the Domestic
Fund. No amendment may be made to any provision of this Agreement which
contemplates action by a vote or consent of greater than a Majority in Interest
of the Limited Partners without a vote or consent of such greater majority as
therein specified.

     Section 12.4  Severability.
                   ------------

     If any provision of this Agreement, or the application of such provision to
any person or circumstance, shall be held invalid, the remainder of this

     Section 12.14  Avoidance of Trade or Business Status; Service-Related
                    ------------------------------------------------------
Income.
- - ------

Notwithstanding anything to the contrary in this Agreement or otherwise:

     (a)   The General Partner will use its best efforts to conduct the affairs
of the Partnership so as to (i) avoid having the Partnership treated as engaged
in a trade or business within the United States for purposes of Sections 864,
875, 882, and 1446 of the Code, (ii) conduct the affairs of the Partnership so
that the Partnership does not invest in United States real property interests as
that term is defined in Section 897 of the Code, and (iii) avoid investing or
entering into contracts for the purchase or sale of commodities or in options or
futures, including currency futures, other than options or other contracts for
the acquisition or disposition of securities of a portfolio company.

     (b)   Neither the General Partner, the Partnership, the principals of the
General Partner nor any agents of the foregoing (in each case in their
capacities as such, including actions relating to the Domestic Fund and the
Prior Funds) shall:

     (i)   engage in investments for the purpose of realizing a quick, immediate
           and profitable sale rather than holding the investment for long-term
           capital appreciation;

     (ii)  invest in portfolio companies for relatively short holding periods,
           (e.g., engaging in quick sales in response to market fluctuations),
           or engage in frequent, short-term turnover of investments in
           portfolio companies (including leveraged financings, short sales,
           puts, calls, hedging transactions and purchases on margin) or a large
           number of such transactions;

     (iii) acquire an interest in a partnership, limited liability company,
           trust or other non-corporate entity that is engaged in a U.S. trade
           or business within the meaning of the Code;

     (iv)  receive a fee for any management-, consulting- or promotion-type
           services provided to Portfolio Companies; or

                                      -52-


     (v)  engage in the management of the day-to-day operations of Portfolio
          Companies or perform any sustained or ongoing services; provided that
          no such persons shall be prohibited from serving as a member of the
          board of directors of Portfolio Companies.

          Accordingly, the General Partner agrees, to the extent legally
permissible, to file all federal, state and local tax returns and reports of the
Partnership in a manner consistent with such limitations.  The General Partner
shall not cause the Partnership to invest in any other partnership unless such
other partnership agrees to use its best efforts to conduct its activities in a
manner such that those activities will not cause the Partnership to be engaged
in a trade or business within the United States for purposes of Sections 875,
882, 897 and 1446 of the Code.

     Section 12.15  Confidentiality.
                    ---------------

     The General Partner and the Partnership on behalf of themselves and their
respective Affiliates, members, managers, employees and other agents (i)
acknowledge, that, during the term of the Partnership, they may become aware of
information relating to the Limited Partners and their respective principals,
clients, Affiliates, partners, members, managers, employees, consultants and
other agents, and (ii) agree, except as otherwise may be required by applicable
law, to keep such information in strict confidence. In the event that the
General Partner or the Partnership or any of their Affiliates or such other
related persons is requested by any governmental body or in any legal proceeding
to disclose information concerning any of the above persons or entities, such
person will provide, to the extent not prohibited by applicable law, prompt
notice to any such person so that such person may seek an appropriate protective
order. This provision shall survive the termination of the Partnership and the
Partnership Agreement.

     Section 12.16  Favorable Arrangements.
                    ----------------------

     The General Partner shall promptly disclose in writing to the Limited
Partners of this Partnership any arrangement, agreement or provision relating to
the Domestic Fund which provides a limited partner of the Domestic Fund with a
material benefit which the Limited Partners of the Partnership do not have. The
Limited Partners shall have thirty (30) days after receipt of such notice to
inform the General Partner that such Limited Partner desires to have such
favorable arrangement, agreement or provision apply to it in relation to the
Partnership and/or this Agreement. Promptly upon receipt of such writing from
the Limited Partner, the General Partner (on behalf of the Partnership) and such
Limited Partner shall legally implement and document such favorable arrangement,
agreement or provision.

                                      -53-


     Section 12.17  Additional Co-Investments.
                    -------------------------

     Subject to the provisions of this Agreement and the Domestic Fund's Limited
Partnership Agreement, the General Partner may, in its discretion, request that
any Portfolio Company or other company offer each Limited Partner the
opportunity to acquire the securities of such company (the "Additional
Securities"). Any such offer shall be made pro rata to each Limited Partner
based on its Capital Commitment and the capital commitment of the partners of
the Domestic Fund, provided that strategic partners of the CMGI Funds or the
Domestic Fund may be offered in excess of their pro rata shares if and to the
extent such an investment would benefit the Portfolio Company. In the event that
one or more of such Limited Partners desires to acquire such Additional
Securities, such investment shall be made outside of the Partnership (either
directly or in an entity to be designated by any such Limited Partner), and each
Limited Partner that so invests shall agree to pay the General Partner an amount
in cash or in-kind (in the discretion of the Limited Partner) equal to ten
percent (10%) of the appreciation in value, if any, of the Additional
Securities, such amount to be determined and payable upon the earlier of (i) the
disposition of such Additional Securities by such Limited Partner (or its
designee), (ii) in the case of Additional Securities issued by Portfolio
Companies of the Partnership, the distribution or liquidation by the Partnership
of the securities of such company, or (iii) in the case of Additional Securities
issued by companies which are not Portfolio Companies of the Partnership, the
termination of the Partnership. In the event that Additional Securities have
been issued by Portfolio Companies of the Partnership or the Domestic Fund, the
General Partner shall sell or otherwise dispose of the Additional Securities at
the same time and based upon the same terms and conditions (including but not
limited to price) as the Partnership's or Fund's sale or disposal of securities
of such portfolio company.

                                      -54-


     IN WITNESS WHEREOF, the parties to this Agreement have executed the same as
of the date first above set forth.
