                        AGREEMENT OF LIMITED PARTNERSHIP

      NOW, THEREFORE, the parties hereto agree as follows:

                                    ARTICLE 1
                               GENERAL PROVISIONS

      SECTION 1.04. Continuation of the Partnership. The parties hereto hereby
agree to continue the Partnership as a limited partnership under and pursuant to
the Delaware Act.

      SECTION 1.05. Purposes of the Partnership. The purposes of the Partnership
are (a) to identify potential Partnership Investments, (b) to acquire, hold and
dispose of Partnership Investments, and (c) pending utilization or disbursement
of funds of the Partnership, to invest such funds in accordance with the terms
of this Agreement, in each case consistent with the objectives described in the
Confidential Offering Memorandum. The Partnership shall have the power to do any
and all acts necessary, appropriate, desirable, incidental or convenient to or
for the furtherance of the purposes described in this Section 1.05, including,
without limitation, any and all of the powers that may be exercised on behalf of
the Partnership by the General Partner pursuant to this Agreement.

      SECTION 1.06. Liability of the Partners Generally. (a) Except as otherwise
provided in the Delaware Act, the General Partner shall have the liabilities of
a partner in a partnership without limited partners to any Person other than the
Partnership and the Limited Partners. Except as otherwise provided in this
Agreement or the Delaware Act, the General Partner shall have the liabilities of
a partner in a partnership without limited partners to the Partnership and each
Limited Partner.

      (b) Except as otherwise provided in this Agreement or the Delaware Act, no
Limited Partner (or former Limited Partner) shall be obligated to make any
contribution to the Partnership or have any liability for the debts and
obligations of the Partnership.

      SECTION 1.07. Admission of Limited Partners; Additional Limited Partners;
Increase of Capital Commitments. (a) On the first Closing Date, each Person
whose subscription for a limited partner interest in the Partnership has been
accepted by the General Partner shall become a Limited Partner (and shall be
shown as such on the books and records of the Partnership) upon (i) execution
and delivery by (or, pursuant to a power of attorney, on behalf of) such Person
and the General Partner of counterparts of this Agreement and (ii) making a
Capital Contribution in accordance with Section 5.01.

      (b) On the first Closing Date, following the admission of any Limited
Partner to the Partnership, the initial Limited Partner shall withdraw from the
Partnership and shall be entitled to receive the return of his contribution
without interest or deduction.

                                       2

      (c) At any time during the Commitment Period, the General Partner may
cause the Partnership to admit additional Limited Partners or to allow any
existing Limited Partner to increase its original Capital Commitment. A Person
shall become such an additional Limited Partner (and shall be shown as such on
the books and records of the Partnership) upon execution and delivery by (or,
pursuant to a power of attorney, on behalf of) such Person and the General
Partner of counterparts of this Agreement, subject to the terms of this Section
1.07. Neither the admission of any additional Limited Partner to the Partnership
nor the increase in the original Capital Commitment of any existing Limited
Partner pursuant to this Section 1.07 shall require the approval of any Limited
Partner existing immediately prior to such admission or increase.

      (d) Any additional Limited Partner admitted to the Partnership on any
Closing Date other than the first Closing Date (and, to the extent of any
increase in its Capital Commitment on any such subsequent Closing Date, any
Limited Partner so increasing its Capital Commitment) (each such Limited
Partner, a "New Commitment Partner", and each such Limited Partner's new or
increased Capital Commitment, a "New Commitment") shall pay to the Partnership
an amount equal to Capital Contributions requested in accordance with Section
5.01 with respect to such New Commitment (pro rated, if necessary, for the
remainder of the then-current semi- annual period).

      (e) On the first Closing Date, or during the 30 days immediately following
the first Closing Date (the "Initial Closing Period"), the General Partner will
cause the Partnership and the Related Funds to make an Investment in the
securities identified on Schedule 1 hereto (the "Pre-Closing Investments"), and
the General Partner will transfer the Pre-Closing Investments to the Partnership
and Related Funds. Each transfer of a Pre-Closing Investment shall be treated as
a contribution by the General Partner to the Partnership of such Pre-Closing
Investment and shall result in an increase in the capital account of the General
Partner in an amount (the "Designated Amount") equal to the sum of (i) the
original acquisition cost of the Pre-Closing Investment (the "Original
Acquisition Cost") and (ii) a notional interest charge in respect of the
Original Acquisition Cost equal to 6% per annum calculated from the date of
original acquisition of such Pre-Closing Investment by the General Partner until
the effective date of the transfer of such Pre-Closing Investment to the
Partnership and the Related Funds (the "Contribution Date"), net of any payments
received by the General Partner prior to the Contribution Date in respect of
such Pre-Closing Investment. Each Limited Partner admitted on or prior to the
Contribution Date shall, on or prior to the date on which such Limited Partner
is admitted, make Capital Contributions in accordance with Section 5.01 with
respect to such Pre-Closing Investments and any additional Capital Contributions
as may be requested by the General Partner for Temporary Cash Funds. As of the
Contribution Date, each Partner will be deemed to have made an investment in
each Pre-Closing Investment, and the Invested Capital of each Partner will be
equal to its Available Commitment Percentage of the Designated Amount for such
Pre- Closing Investment. The amounts contributed to the Partnership by the
Limited Partners in respect of any Pre-Closing

                                       3

Investment shall be distributed promptly to the General Partner until the
General Partner has received an amount equal to 99% of the Designated Amount.

      (f) No New Commitment Partner admitted after the Initial Closing Period
shall, with respect to its New Commitment, participate in any Investment made by
the Partnership prior to the Closing Date on which such New Commitment is made
to the Partnership.

      (g) Notwithstanding any other provision of this Agreement, the Partnership
and the General Partner, on its own behalf or on behalf of the Partnership,
shall enter into and carry out the terms of the Management Agreement,
subscription agreements with the Limited Partners, and any other agreements to
induce a Person to purchase a limited partner interest in the Partnership (each,
a "Side Letter"), without any further act, approval or vote of any Partner or
other Person.

                                    ARTICLE 2

                                       6

      SECTION 2.03. Other Authority. The General Partner agrees to use its
reasonable best efforts to operate the Partnership in such a way that (i) the

(B)(i) thereunder), (ii) none of the Partnership's assets would be deemed to be
"plan assets" for purposes of ERISA, (iii) the General Partner and the Manager

the General Partner, the Manager, Greenhill and any Affiliate of any such Person
would be in compliance with any other material law, regulation or guideline
applicable to the Partnership, the General Partner, the Manager, Greenhill or
such Affiliate. The General Partner is hereby authorized to take any action it
has determined in good faith to be necessary or desirable in order for (i) the
Partnership not to be in violation of the Investment Company Act, (ii) the
Partnership's assets not to be deemed to be "plan assets" for purposes of ERISA,
(iii) the General Partner and the Manager not to be in violation of the Advisers

require the approval of any Limited Partner.

      SECTION 2.04. Borrowings by the Partnership. The General Partner shall
have the right, in its sole discretion, to cause the Partnership to borrow money
from, or guarantee the indebtedness of, any Person (including the General
Partner or any Affiliate of the General Partner); (i) to finance investments in
advance of drawdowns pursuant to Article 5 (provided that such borrowings or
guarantees shall not be incurred in an amount in excess of the aggregate
Available Capital Commitments) or (ii) for short-term cash management purposes
in connection with the activities of the Partnership (provided that such
borrowings and guarantees shall not exceed $2 million in outstanding principal
amount borrowed or guaranteed at any time).

      SECTION 2.05. Other Activities. (a) Each Investor (i) represents and
warrants that such Investor has carefully reviewed and understood the
information contained in the Confidential Offering Memorandum, and (ii)
acknowledges and agrees that the General Partner, the Manager, Greenhill or any
of their respective Affiliates may engage, without liability to the Partnership
or the Limited Partners except as provided in Section 9.01(a), in any and all of
the activities of the type or character described or contemplated in this
Section 2.05 and in the Confidential Offering Memorandum under the caption "Risk
Factors--Other Fees", "--Other Activities" and "--Potential Conflicts of
Interest" or elsewhere therein, whether or not such activities have or could
have an effect on the Partnership's affairs (or, if

                                       7

applicable, on any Parallel Investor's affairs) or on any Investment, and that
no such activity will in and of itself constitute a breach of any duty owed by
any Indemnified Person to the Limited Partners or the Partnership. Without
limiting the generality of any of the foregoing, the General Partner and each
Investor acknowledge and agree that:

            (A) although the General Partner intends generally to identify
      appropriate investment opportunities for the Partnership (and, if
      applicable, for any Parallel Investor), none of the General Partner,
      Greenhill or any of their respective Affiliates shall have any obligation
      under this Agreement, except as (and only to the extent) provided in
      Section 3.05, to offer to the Partnership or any Investor any particular
      investment opportunity;

            (B) (1) the General Partner, the Manager, Greenhill and any of their
      respective Affiliates, and any officer or employee of any such Person
      shall be required to devote only such time to the affairs of the
      Partnership, any Partnership Investment Vehicle, any Parallel Investment
      Vehicle and any Parallel Investment as they shall determine in their
      reasonable discretion may be necessary or appropriate to manage and
      operate the Partnership, any Partnership Investment Vehicle, any Parallel
      Investment Vehicle and any Parallel Investment, and each such Person, to
      the extent not otherwise directed by the General Partner (but subject to
      Section 3.05(b) and the other provisions of this Agreement), shall be free
      to serve and may be compensated by any other Person or enterprise in any
      capacity (including serving the Partnership in any capacity other than as
      a general partner or as an investment advisor or otherwise) that it may
      deem appropriate in its discretion; and (2) the General Partner may enter
      into incentive arrangements with Persons not associated with the General
      Partner or Greenhill as it deems appropriate in consideration of their
      providing services in connection with sourcing of Investments; and

            (C) in addition to the transactions specifically contemplated by
      this Agreement, Greenhill and any of its Affiliates shall have the right
      to perform services for, and to receive compensation from, the
      Partnership, any Partner (including, if applicable, as a Parallel
      Investor), any Partnership Investment Vehicle, any Parallel Investment
      Vehicle, any Related Fund, any Portfolio Company or Related Person
      (whether before or after or in connection with the making of the
      applicable Investment). Subject to Section 2.05(a)(ii)(D), such
      compensation may include, without limitation, investment banking or
      advisory fees, fees in connection with restructurings and mergers and
      acquisitions, and underwriting or placement fees. In addition, Greenhill,
      each such Affiliate and any officer or employee of any such Person shall
      have the right to purchase property (including securities) from, to sell
      property (including securities) or lend funds to, or otherwise to deal
      with, the Partnership, any Partner (including, if applicable, as a
      Parallel Investor), any Partnership Investment Vehicle, any Parallel
      Investment Vehicle, any Related Fund, any Portfolio Company or any Related
      Person (whether before or after or in connection with the making of the
      applicable Investment); provided that any such dealing (other

                                       8

      than those specifically contemplated by this Agreement) shall not
      otherwise be in violation of this Agreement; and provided further that
      each Limited Partner hereby consents to the contribution of Pre-Closing
      Investments by the General Partner to the Partnership. Each Investor
      further acknowledges and agrees that the performance of such services, the
      purchase or sale of such property, the lending of such funds, other
      dealings, or the receipt of such compensation may give rise to conflicts
      of interest between the Partnership and the Investors (including, if
      applicable, as Parallel Investors), on the one hand, and Greenhill, such
      Affiliate, or such officer or employee, on the other hand, and that,
      except as specifically provided otherwise in this Agreement, any such
      compensation will not be shared with the Partnership or any Investor;

            (D) any fees or other compensation received by Greenhill or any of
      its Affiliates from the Partnership, any Partner (including, if
      applicable, as a Parallel Investor), any Partnership Investment Vehicle,
      any Parallel Investment Vehicle, any Related Fund, any Portfolio Company
      or Related Person at any time during the period the Partnership holds an
      Investment in the relevant Portfolio Company will be reasonable and will
      not exceed the amount that Greenhill or such Affiliates would customarily
      receive from third parties as fees or other compensation at such time for
      the performance of similar services in an arm's-length transaction;
      provided that the limitations set forth in this sentence shall be deemed
      to be satisfied with respect to the terms specifically contained in this
      Agreement; and

            (E) Greenhill, the General Partner and their respective Affiliates
      shall not lend money to the Partnership on other than arm's-length terms.

      (b) Nothing contained in this Agreement shall be deemed to limit in any
respect the ability of any Investor (or Affiliate thereof), in its individual
capacity, from making investments in, or otherwise engaging in business with,
any Portfolio Company or in any Person in which Investments are proposed to be
made or in any Affiliate of any such Person or from providing financing thereto,
in addition to such Investor's Capital Contributions, if any, pursuant to this
Agreement.

      SECTION 2.06. Books and Records; Accounting Method; Fiscal Year. (a) The

such books and records. Subject to Section 2.08(b), such books and records shall
be available, upon 10 Business Days' notice to the General Partner, for
inspection at the offices of the General Partner (or such other location
designated by the General Partner, in its discretion) at reasonable times during
business hours on any Business Day by each Limited Partner or its duly
authorized agents or representatives for a purpose reasonably related to such
Limited Partner's interest in the Partnership. Each Limited Partner agrees that
(i) such books and records contain confidential information relating to the
Partnership and its

                                       9

affairs, and (ii) the General Partner shall have the right to prohibit or
otherwise limit, in its reasonable discretion, the making of any copies of such
books and records.

books of account shall be kept on the same basis followed by the Partnership for
U.S. federal income tax purposes.

required to be filed for the Partnership. Subject to Section 13.14, the General
Partner may, in its discretion, make, or refrain from making, any income or
other tax elections for the Partnership that it deems necessary or advisable,
including an election pursuant to Section 754 of the Code; provided that neither
the General Partner nor any other Person shall make an election or take any
other action that would cause the Partnership to be treated as a corporation, an
association taxable as a corporation for U.S. income tax purposes or an
"electing large partnership" under Section 775 of the Code. Each Limited Partner
shall be responsible for preparing and filing all tax returns required to be
filed by such Limited Partner.

      (b) The General Partner is hereby designated as the Partnership's "Tax
Matters Partner" under Section 6231(a)(7) of the Code. The General Partner is

including filing any forms or documents with the Internal Revenue Service and
taking such other action as may from time to time be required under Treasury
regulations. Expenses of any administrative proceedings undertaken by the Tax
Matters Partner shall be Partnership Expenses. Each Limited Partner who elects
to participate in such proceedings shall be responsible for any expenses
incurred by such Limited Partner in connection with such participation. The cost
of any resulting audits or adjustments of a Limited Partner's tax return shall
be borne solely by the affected Limited Partner.

      (c) Each Limited Partner shall notify the General Partner in a timely
manner of its intention to: (i) file a notice of inconsistent treatment under
Section 6222(b) of the Code; (ii) file a request for administrative adjustment
of Partnership items; (iii) file a petition with respect to any Partnership item
or other tax matters involving the Partnership; or (iv) enter into a settlement
agreement with the Secretary of the Treasury with respect to any Partnership
items. Upon any such notification, the General Partner may, if it agrees with
such Limited Partner's position, elect (at its discretion) to make such filing
or enter into such agreement, as applicable and practicable, on behalf of the
Partnership. The cost of any resulting audits or adjustments of a Limited
Partner's tax return shall be borne solely by the affected Limited Partner.

                                       10

      (d) The General Partner may, in its discretion, take appropriate steps on
behalf of the Partnership that it deems necessary or advisable to comply with
the tax laws of non-U.S. jurisdictions.

      (e) The General Partner shall use reasonable efforts to operate the
Partnership in a manner that it believes, based on the advice of qualified
counsel, does not cause any Limited Partner, by reason of its investment in the
Partnership, to become subject to net income tax in any foreign jurisdiction
with respect to income from sources other than the Partnership within that
jurisdiction.

      SECTION 2.08. Confidentiality. (a) Each Investor agrees to keep

Investor and its Authorized Representatives may make such disclosure to the
extent that (i) the information being disclosed is publicly known at the time of
proposed disclosure by such Investor or Authorized Representative, (ii) the
information otherwise is or becomes legally known to such Investor other than

Greenhill or any of their respective Affiliates, (iii) such disclosure, in the
written opinion of legal counsel (including internal counsel) reasonably
acceptable to the General Partner, is required by law or regulation, (iv) such
disclosure is required to be made to any regulatory authority or self-regulatory

may not be amended without the consent of the General Partner, (vi) such
disclosure is required in connection with the enforcement of any legal rights

                  (A) in part as a Partnership Investment, and

                  (B) subject to Section 3.03(d) and in accordance with and
            subject to the provisions of Article 7, in part as a Parallel
            Investment by structuring the investment to be made by the General
            Partner and/or any Investor (other than any ERISA Partner),
            individually or together with other Parallel Investors, as an
            investment outside the Partnership (directly by such Investor and/or
            indirectly by the General Partner and such Investor through one or
            more Parallel Investment Vehicles); and

            (ii) if such Investment is structured in whole or in part as a
      Partnership Investment, such Partnership Investment may be made in whole
      or in any part as an investment directly by the Partnership and/or through
      one or more Partnership Investment Vehicles.

      If investments in such class or series pursuant to such investment
opportunity are made pursuant to the foregoing provisions of this Section
3.03(b) as separate Investment Portions, each Investment Portion shall be funded
by Capital Contributions made by, and gains, losses, certain Investment Expenses
and other items with respect to such Investment Portion shall be distributed and
allocated to, the Participating Investors in such Investment Portion in
accordance with the provisions of this Agreement. The Investors acknowledge and
agree that (x) the General Partner shall make all determinations with respect to
structuring Investments pursuant to the foregoing provisions of this

                                       16

Section 3.03(b) in its discretion, (y) the General Partner shall in no event be
obligated to structure any Investment in order to address or give effect to the
individual objectives or considerations of any Investor or group of Investors,
and (z) the General Partner shall have no liability to the Partnership or any
Investor arising from any such determination or from structuring any Investment
in any particular manner except for any liability resulting from the General
Partner's gross negligence or willful misconduct; provided that the General
Partner shall have no liability to any Investor arising solely from its
determination to structure an Investment pursuant to Section 3.03(a) rather than
pursuant to this Section 3.03(b).

      (c) Investment Size of Each Investor in Different Investment Portions.
With respect to each class or series of securities of a Portfolio Company in
which an Investment is made pursuant to Section 3.03(b),

            (i) it is understood that each Investor shall be required to make a
      Capital Contribution in respect of such Investment in such class or series
      in an amount determined in accordance with Section 5.02;

            (ii) if such Investment in such class or series is structured to
      consist of separate Investment Portions and the General Partner causes
      different groups of Investors to be Participating Investors in different
      Investment Portions, (A) no Investor shall be a Participating Investor in
      more than one Investment Portion with respect to the same Investment, and
      (B) any Investor that makes an aggregate Capital Contribution in
      accordance with clause (i) of this Section 3.03(c) with respect to one
      Investment Portion shall be deemed to have an Available Capital Commitment
      equal to zero for purposes of all other Investment Portions (if any)
      comprising such Investment; and

            (iii) the General Partner shall be permitted (but shall not be
      required) to make Capital Contributions in respect of one or more
      Investment Portions with respect to such Investment; provided that if the
      General Partner makes an aggregate Capital Contribution in accordance with
      clause (i) of this Section 3.03(c) with respect to such Investment Portion
      or Investment Portions, the General Partner shall be deemed to have an
      Available Capital Commitment equal to zero for purposes of all other
      Investment Portions (if any) comprising such Investment.

      (d) Structuring of Parallel Investments. Notwithstanding any provision in
this Agreement to the contrary:

            (i) no Investment shall be structured in any part as a Parallel
      Investment pursuant to Section 3.03(b) at any time if (A) the structuring
      or making of such Parallel Investment would have a material adverse effect
      at such time on any Limited Partner (including the loss of limited
      liability) or on any Limited Partner's interest in the applicable
      Investment and (B) such effect

                                       17

      would be avoided at such time were the applicable Investment to consist
      entirely of a Partnership Investment;

            (ii) no ERISA Partner shall be permitted or required to make a
      Capital Contribution in respect of, or to participate in, any Parallel
      Investment;

            (iii) no Investor shall be permitted or required to make a Capital
      Contribution in respect of, or to participate in, any Parallel Investment
      if participation by such Investor in such Parallel Investment would result
      in a violation of law by such Investor;

            (iv) in connection with a single investment opportunity, no Investor
      shall be permitted or required to make a Capital Contribution with respect
      to, or to participate in, both a Partnership Investment and a Parallel
      Investment in respect of the same class or series of securities of a
      Portfolio Company (provided that the General Partner shall be permitted
      (but shall not be required) to make a Capital Contribution with respect
      to, and to participate in, both a Partnership Investment and a Parallel
      Investment with respect to the same Investment); and

            (v) no Investor shall be permitted or required to make a Capital
      Contribution with respect to, or to participate in, any proposed Parallel
      Investment pursuant to a single investment opportunity unless a
      Partnership Investment also has been, or concurrently will be, made
      pursuant to such investment opportunity in securities of the same class or
      series as those comprising such proposed Parallel Investment.

      (e) Certain Rules Regarding Investments and Investment Portions. For
purposes of this Agreement:

            (i) whenever an Investment is structured as described in Section
      3.03(b), each of the following components of such Investment shall
      constitute a separate "Investment Portion":

                  (A) a direct investment by the Partnership;

                  (B) each investment by the Partnership through a separate
            Partnership Investment Vehicle;

                  (C) each direct investment by a Parallel Investor; and

                  (D) each investment (by one or more Parallel Investors)
            through a separate Parallel Investment Vehicle;

                                       18

            (ii) all securities of a Portfolio Company of the same class or
      series that are acquired at the same price pursuant to a single investment
      opportunity under this Agreement shall be treated as a single
      "Investment," regardless of whether such securities are acquired (A) in a
      single transaction or a series of related transactions, (B) in part as a
      Partnership Investment and in part as a Parallel Investment, or (C)
      through one or more Investment Portions (provided that (x) the securities
      issued upon exercise, exchange or conversion of any Convertible Securities
      shall constitute the same Investment as the Investment in such Convertible
      Securities and (y) a Follow-On Investment shall be treated as a separate
      Investment from the Investment (the "Original Investment") to which such
      Follow-On Investment relates);

            (iii) all securities of a Portfolio Company of the same class or
      series acquired pursuant to a single investment opportunity (A) if
      acquired by the Partnership (directly and/or indirectly through one or
      more Partnership Investment Vehicles), shall be treated as a single
      Partnership Investment, and (B) if acquired by one or more Parallel
      Investors (directly or indirectly through one or more Parallel Investment
      Vehicles), shall be treated as a single Parallel Investment of such
      Participating Parallel Investors;

            (iv) different classes or series of securities of a Portfolio
      Company shall be treated as separate Investments, regardless of whether
      such securities are acquired pursuant to a single investment opportunity;
      and

            (v) different classes or series of securities of a Portfolio Company
      (A) if acquired by the Partnership, shall be treated as separate
      Partnership Investments, and (B) if acquired by one or more Parallel
      Investors, shall be treated as separate Parallel Investments.

      SECTION 3.04. Investment Committee. The Limited Partners (including, if
applicable, as Parallel Investors) acknowledge, approve and agree that (i) the
General Partner may delegate the authority to approve all Investments and/or all
dispositions thereof to a committee which is comprised of officers or employees
of the General Partner, Greenhill or their respective Affiliates, which officers
or employees shall be selected by the General Partner in its sole discretion and
(ii) any such approval of an Investment or disposition thereof by such committee
shall be conclusive and no further action or determination by the General
Partner shall be required with respect to such approval. The General Partner
may, in its discretion, at any time change the composition of or the number of
persons serving on such committee and any appointments made by the General
Partner shall be conclusive upon the Partnership and all of the Limited Partners
(including as Parallel Investors). Notwithstanding anything to the contrary
contained in this Agreement, in no event shall a member of any such committee be
considered a general partner of the Partnership by agreement, estoppel, as a
result of the performance of its duties, or otherwise.

                                       19

      SECTION 3.05. Restriction on Activities by Greenhill Entities; Obligation
to Offer. (a) Until the termination of the Commitment Period, Greenhill, the
General Partner and their respective Affiliates may not participate in the
management of any new limited partnership (or other pooled investment vehicle or
entity) which has investment objectives that are substantially the same as the
objectives of the Partnership (a "Competing Fund"); provided that this Section
3.05(a) shall not apply to (i) any Related Fund, including those organized after
the first Closing Date or (ii) the Barrow Street Fund (or related or successor
funds).

      (b) Until the termination of the Commitment Period, Greenhill, the General
Partner and their respective Affiliates will offer to the Partnership and the
Related Funds the exclusive opportunity to invest in Private Equity Securities
in the United States, Canada and Europe that are made available to Greenhill,
the General Partner or any such Affiliate for investment as principal for its
own account and that fit the investment criteria of the Partnership; provided
that this Section 3.05(b) shall not apply to (i) any investment or acquisition
made by Greenhill, the General Partner or any of their respective Affiliates for
strategic purposes or otherwise in connection with or incidental to the
operating business of any such Person; (ii) any investment opportunity developed
or originated by an unaffiliated third party co-investor or joint venture
partner and made available only specifically to Greenhill, the General Partner
or one of their respective Affiliates pursuant to a contractual obligation or a
fiduciary duty of such third party; (iii) any investment related to any existing
investment of Greenhill, the General Partner or one of their respective
Affiliates; (iv) any investment received by Greenhill, the General Partner or
one of their respective Affiliates as compensation for investment banking or
advisory services; (v) any investment made in real estate or real estate related
companies, any investment by the Barrow Street Fund (or related or successor
funds) or other funds having the investment objective of investing primarily in
real estate or real estate related companies; and (vi) any investment of $3
million or less (determined in the aggregate for Greenhill, the General Partner
and their respective Affiliates). Greenhill, the General Partner or any of their
respective Affiliates may make any investment that the General Partner elects
not to make on behalf of the Partnership, and the General Partner will disclose
any such investment at the next succeeding meeting of the LP Advisory Committee.

      SECTION 3.06. Related Funds. (a) The Limited Partners acknowledge and
agree that the General Partner may establish an investment vehicle or vehicles
to co-invest with the Partnership in investment opportunities on a side-by side
basis (each, a "Related Fund").

      (b) In connection with each investment opportunity pursuant to which any
Investment is made under this Agreement at any time, each Related Fund shall, to
the extent such Related Fund has funds available for investment, co-invest with
the Partnership with respect to each Investment made pursuant to such investment
opportunity on terms substantially the same as those applicable to the
corresponding Investment in such investment opportunity, except to the extent
necessary to address regulatory or other legal considerations (it being
understood that the terms applicable to the investors of such Related Fund may
differ from the terms applicable to the Limited Partners, including whether such
investors will

                                       20

be subject to a management fee or a carried interest). Each co-investment by a
Related Fund in the securities of a Portfolio Company shall be made in the same
class or series of securities as the Investment by the Partnership in an amount
that is in the same proportion to the aggregate Investment by the Partnership as
the proportion that the aggregate capital commitments of such Related Fund bears
to the Overall Commitment of the Partnership, except, in either case, to the
extent necessary to address regulatory or other legal considerations.

      (c) A Related Fund shall not at any time sell, exchange, transfer or
otherwise dispose of any securities that were acquired as a co-investment with
the Partnership in the same investment opportunity as contemplated by Section
3.06(b) unless (i) the Partnership also sells, exchanges, transfers or otherwise
disposes of, at substantially the same time, securities that were acquired by
the Partnership in such investment opportunity (it being understood that the
Disposition of securities comprising all or part of an Investment shall be
effected in accordance with Section 3.08), and the aggregate amount of such
securities sold, exchanged, transferred or otherwise disposed of by the
Partnership (and Parallel Investors, if any) and such Related Fund is pro rata
in proportion to the aggregate amount respectively invested by the Partnership
(and Parallel Investors, if any) and such Related Fund in such securities, and
(ii) on terms that, except to the extent necessary to address regulatory or
other legal considerations, are substantially the same as those applicable to
such sale, exchange, transfer or other disposition by the Partnership at such
time (it being understood that in connection with any sale or other disposition
of securities for cash by the Partnership, such Related Fund shall be permitted
to sell or otherwise dispose of securities for cash and/or distribute securities
in kind).

      SECTION 3.07. Additional Investment Situations. If, in connection with an
investment opportunity in respect of Private Equity Securities of a Portfolio
Company, the Partnership (and the Parallel Investors, if any) and each Related
Fund commit to invest in an amount of such Private Equity Securities, and the
amount of Private Equity Securities offered to all such Persons with respect to
such investment opportunity (which amount, in the case of the Partnership and
the Parallel Investors (if any), shall be determined, for purposes of this
Section 3.07, without reference to Section 3.02) exceeds the amount so committed
to be invested, the General Partner may, in its discretion, present to any other
Person or Persons (who may include any Partner, in which case any investment by
such Partner pursuant to this Section 3.07 shall be in addition to its Capital
Contributions, if any, required under this Agreement) the opportunity to make an
investment outside the Partnership (which shall not constitute an Investment
under this Agreement) in all or any portion of the amount of such Private Equity
Securities remaining after taking into account the Investment, if any, by the
Partnership and Parallel Investors, if any, and the investments, if any, by the
Related Funds. Any such investment by any other Person shall be in an amount of
securities and on terms determined by the General Partner in its discretion and
accepted by such Person desiring to make such investment.

                                       21

      Any amount invested by any Investor pursuant to this Section 3.07 shall in
no way affect the Available Capital Commitment of such Investor and any amount
so invested shall not constitute a Capital Contribution for purposes of this
Agreement.

      SECTION 3.08. General Principles on the Disposition of Investments.

      (a) Disposition of Securities Attributable to a Single Investment. Upon
the Disposition of any single class or series of securities, where such
securities are attributable to a single Investment (as determined pursuant to
Section 3.03(e)(ii)) and such securities were acquired in a series of related
transactions, the General Partner shall select the securities for such
Disposition pro rata from each such transaction in proportion to the amount of
Invested Capital at such time with respect to each such transaction. If any
single Investment is structured as more than one Investment Portion, the General
Partner shall select securities for Disposition from each such Investment
Portion, pro rata in proportion to the aggregate amount of Invested Capital at
such time in each such Investment Portion, and if the securities comprising such
Investment were acquired in a series of related transactions, within each
Investment Portion the General Partner shall select the securities for such
Disposition pro rata from each such transaction in proportion to the amount of
Invested Capital in such Investment Portion at such time with respect to each
such transaction.

      (b) Disposition of Securities Attributable to More than One Investment.
Upon the Disposition of any single class or series of securities at any time,
where such securities are attributable to more than one Investment, the General
Partner shall select the securities subject to such Disposition pro rata from
each such Investment, in proportion to the aggregate amount of Invested Capital
at such time in each such Investment. Within each such Investment, the General
Partner shall select the securities subject to such Disposition in accordance
with Section 3.08(a).

      (c) Actions by the General Partner. The General Partner shall take all
actions necessary or desirable, as determined by the General Partner in its
discretion, in order to give effect for United States federal income tax
purposes to the attribution of any cash or other property to particular shares
(or principal amount) of securities as contemplated by this Section 3.08,
including giving instructions to and receiving confirmations from appropriate
Persons evidencing such attribution.

      SECTION 3.09. Non-U.S. Currency Considerations. (a) At the time any cash
is received in a currency other than U.S. dollars for payment (as distributions
or otherwise) to the Investors in connection with any Investment,

            (i) subject to clause (ii) below, if such cash is to be paid to
      Investors (as a distribution or otherwise) in U.S. dollars, the General
      Partner shall effect the conversion of such cash into U.S. dollars, at the
      applicable exchange rate then in effect, as soon as practicable after such
      cash is received; and

                                       22

            (ii) if, pursuant to the last sentence of Section 6.05(a), such cash
      is to be paid to Investors in the currency in which it is received, the
      General Partner shall determine the U.S. dollar equivalent of such cash,
      based upon the applicable exchange rate in effect on the date such cash is
      received, for purposes of Article 6.

      (b) Currency translations in connection with the valuation of non-cash
property that is to be distributed in kind shall be made in the manner set forth
in Section 6.05(b) for purposes of Article 6.

                                    ARTICLE 4
                                    EXPENSES

      SECTION 4.01. Definition and Payment of General Partner Expenses. As
between the General Partner and the Partnership, the General Partner shall be
solely responsible for and shall pay all General Partner Expenses. As used
herein, the term "General Partner Expenses" means all compensation and employee
benefit expenses of employees of the General Partner and the Manager and related
overhead (including rent, utilities, travel, entertainment and other similar
items) resulting from the activities of such employees on behalf of the
Partnership or in connection with this Agreement and Organizational Expenses in
excess of Partnership Organizational Expenses.

      SECTION 4.02. Definition and Payment of Partnership Expenses. (a) The
Partnership shall be responsible for and shall pay all Partnership Expenses. As
used herein, the term "Partnership Expenses" means all expenses or obligations
of the Partnership or otherwise incurred by the General Partner or the Manager
in connection with this Agreement (other than General Partner Expenses, any
Parallel Investment Expenses and the obligation of the Partnership to pay the
purchase price for any Partnership Investment), including:

            (i) all Partnership Organizational Expenses payable by the
      Partnership or the General Partner or any other Person in connection with
      the offering of limited partner interests in the Partnership;

            (ii) all expenses directly attributable to any Partnership
      Investment or proposed Partnership Investment that is ultimately not made
      by the Partnership, including all unreimbursed expenses incurred in
      connection with the making, holding, refinancing, pledging, sale or other
      disposition or proposed refinancing, pledging, sale or other disposition
      of all or any portion of such Partnership Investment, any Partnership
      Investment Vehicle Expenses with respect to such Partnership Investment,
      and any Indemnification Obligation arising with respect to such
      Partnership Investment (collectively, "Partnership Investment Expenses");
      and

                                       23

            (iii) all other expenses of the Partnership incurred in connection
      with the ongoing operation and administration of the Partnership that are
      not reimbursed by a Portfolio Company (collectively, "Partnership
      Administrative Expenses"), including (A) the maintenance of the
      Partnership's books and records, (B) the preparation and delivery to the
      Limited Partners of checks, financial reports, and other information
      pursuant to this Agreement, (C) the holding of annual meetings of the
      Partnership, (D) expenses incurred in connection with the dissolution and
      liquidation of the Partnership, (E) any Indemnification Obligation arising
      other than with respect to any Investment, (F) the Borrowing Costs and (G)
      out-of-pocket expenses incurred by the LP Advisory Committee.

      (b) The parties agree that all of the following (to the extent not
constituting General Partner Expenses) constitute Partnership Expenses, and are
some, but not necessarily all, of the types of expenses that may constitute
Partnership Investment Expenses, Partnership Administrative Expenses or
Organizational Expenses, depending upon the context in which such expenses are
incurred:

            (i) expenses incurred in connection with obtaining legal, tax, and
      accounting advice and the advice of other consultants and experts on
      behalf of the Partnership;

            (ii) expenses incurred in connection with the registration,
      qualification, or exemption of the Partnership under any applicable laws;

            (iii) out-of-pocket expenses incurred in connection with the
      collection of amounts due to the Partnership from any Person;

            (iv) expenses incurred in connection with the preparation of
      amendments to this Agreement;

            (v) any taxes imposed on the Partnership, including any taxes
      imposed on the Partnership or the General Partner in the capacity of
      withholding agent with respect to a Limited Partner (and any interest,
      penalties or expenses relating to any such taxes), and any expenses
      incurred in connection with tax proceedings that are characterized as
      Partnership Expenses pursuant to Section 2.07;

            (vi) expenses incurred in connection with any Proceeding involving
      the Partnership (including the cost of any investigation and preparation)
      and the amount of any judgment or settlement paid in connection therewith;
      provided that (i) any such expenses which, if incurred by any Indemnified
      Person, would not be indemnifiable under Article 9, shall not constitute
      Partnership Expenses and (ii) expenses incurred by an Indemnified Person
      in connection with any litigation brought by or on behalf of one or more
      Limited Partners having at least 20% of

                                       24

      the Overall Capital shall not constitute Partnership Expenses and such
      Indemnified Person shall not be entitled to be indemnified for such
      expenses pursuant to Article 9 until such litigation is resolved, in which
      event such expenses shall become Partnership Expenses and such Indemnified
      Person shall be indemnified as (but only to the extent) provided in
      Article 9; and

            (vii) any Indemnification Obligation and any other indemnity,
      contribution, or reimbursement obligations of the Partnership with respect
      to any Person, whether payable in connection with a Proceeding involving
      the Partnership or otherwise.

      SECTION 4.03. Responsibility for Partnership Expenses Among the Partners.
The Partners agree that, as among the Partners, responsibility for Partnership
Expenses shall be determined as set forth in this Section 4.03 and shall be paid
out of the funds set forth in Section 4.04 at such time after such Partnership
Expenses arise as the General Partner determines in its discretion:

      (a) General Rule for Funding of Partnership Expenses. Except as set forth
in Section 4.03(b), any Partnership Expense shall be funded by the Partners pro
rata in accordance with their respective Commitment Percentages.

      (b) Exceptions to the General Rule for Funding of Partnership Expenses.
Notwithstanding Section 4.03(a):

            (i) subject to clauses (ii) and (vi) below, any Partnership
      Investment Expenses directly attributable to any Partnership Investment
      shall be funded by only those Partners who are Participating Partners with
      respect to such Partnership Investment (but not by any other Partner), pro
      rata in accordance with their respective Partnership Investment
      Percentages with respect to such Partnership Investment; provided that any
      Indemnification Obligation directly attributable to any Investment shall
      be funded by those Investors who are Participating Investors (including,
      if applicable, as Parallel Investors) with respect to the applicable
      Investment (but not by any other Investor), pro rata in accordance with
      their respective Investment Percentages with respect to such Investment;

            (ii) subject to clause (vi) below, with respect to a Partnership
      Investment for which any Partnership Investment Vehicle is formed, the
      Partnership Investment Vehicle Expenses attributable to such Partnership
      Investment Vehicle shall be funded by only those Participating Investors
      who participated in such Partnership Investment through such Partnership
      Investment Vehicle (calculated on the basis of such Participating
      Partners' respective Investment Percentages without giving effect to the
      Invested Capital of any Participating Investor who did not participate
      through such Partnership Investment Vehicle);

                                       25

            (iii) any Partnership Investment Expense with respect to any
      proposed Partnership Investment that is ultimately not made by the
      Partnership shall be funded by the Partners, pro rata in accordance with
      their respective Available Commitment Percentages;

            (iv) in the event that any Limited Partner initiates any Proceeding
      against the Partnership or the LP Advisory Committee and a judgment or
      order not subject to further appeal or discretionary review is rendered in
      respect of such Proceeding in favor of the Partnership or the LP Advisory
      Committee, as the case may be, such Limited Partner shall be solely liable
      for all costs and expenses of the Partnership or the LP Advisory
      Committee, as the case may be, attributable thereto;

            (v) the Partners' respective shares of Partnership Expenses may be
      adjusted to reflect the share of Partnership Expenses of any New
      Commitment Partner pursuant to Section 1.07(d); and

            (vi) the General Partner may determine that any Partnership Expense
      shall be funded by the Partners on a basis other than Commitment
      Percentages, Available Commitment Percentages, Partnership Investment
      Percentages or Investment Percentages, as the case may be, and/or by
      certain (but not all) Partners if the General Partner reasonably
      determines that such other basis is clearly more equitable.

      SECTION 4.04. Sources of Funds for Funding by the Partners of Partnership
Expenses. The Partners acknowledge that Partnership Expenses shall be funded by
or for the account of the Partners, to the extent provided in Section 4.03,
through any one or more of the following sources of funds of the Partnership,
determined by the General Partner in its discretion:

            (i) Capital Contributions by the Partners in accordance with Article
      5;

            (ii) the withholding, pursuant to Section 6.05, of amounts (whether
      realized through the sale of Partnership assets or otherwise)
      distributable to the Partners;

            (iii) reserves set aside pursuant to Section 6.05; or

            (iv) amounts required to be contributed by the Limited Partners
      pursuant to Section 9.03 in the case of Partnership Expenses arising from
      any Indemnification Obligation.

                                       26

      SECTION 4.05. Non-Applicability of Article 4 to Parallel Investment
Expenses. The provisions of Sections 4.03 and 4.04 shall not apply, and the
provisions of Section 7.02 shall apply, with respect to any Parallel Investment
Expenses.

                                    ARTICLE 5
                  CAPITAL COMMITMENTS AND CAPITAL CONTRIBUTIONS

      SECTION 5.01. Capital Commitments. (a) Each Partner hereby agrees:

            (i) to make Capital Contributions in respect of Temporary Cash Funds
      and Investments (other than Follow-On Investments) from time to time as
      hereinafter set forth in this Article 5; provided that the applicable
      Drawdown Notice with respect to any Capital Contribution by a Partner in
      respect of Temporary Cash Funds or an Investment (other than a Follow-On
      Investment) is delivered to such Partner prior to the termination of the
      Commitment Period (except that such Drawdown Notice may be delivered to
      such Partner after the termination of the Commitment Period if such
      Drawdown Notice relates (A) to an Investment (other than a Follow-On
      Investment) that the Partnership committed to make prior to the
      termination of the Commitment Period or (B) to an Investment in
      Convertible Securities in connection with the exercise, exchange or
      conversion of such Convertible Securities); and

            (ii) to make Capital Contributions in respect of Expenses and
      Follow-On Investments from time to time (whether before or after
      termination of the Commitment Period) as hereinafter set forth in this
      Article 5; provided that (A) the aggregate amount of Follow-On Investments
      made at any time after the termination of the Commitment Period shall not
      exceed the lesser of (x) 15% of the aggregate Capital Commitments of all
      the Partners at such time and (y) the aggregate Available Capital
      Commitments of the Investors and (B) any such Follow-On Investment must be
      made on or prior to the second anniversary of the termination of the
      Commitment Period.

      Notwithstanding anything contained in this Agreement (except as otherwise
provided in Sections 5.04(f)(ii), 5.05 and 10.05), no Partner shall be required
to make any Capital Contribution if, at the time such Capital Contribution is to
be made, such Capital Contribution exceeds such Partner's then Available Capital
Commitment.

      (b) The General Partner may, in its discretion, terminate the Commitment
Period at any time if:

                                       27

            (i) at such time, at least 70% of the Overall Capital has
      theretofore been drawn down for Investments or expenses (or committed for
      such purposes) at such time; or

            (ii) the General Partner determines in its discretion that any
      applicable law or regulation makes it necessary to terminate the
      Commitment Period.

      (c) The Capital Commitment of the General Partner at any time shall be
equal to 1% of the aggregate Capital Commitments of all the Partners at such
time.

      (d) Notwithstanding anything else in this Agreement, on or shortly after
the first Closing Date, each Partner shall pay to the Partnership, as its
initial Capital Contribution, an amount as determined by the General Partner in
its sole discretion (with at least three Business Days' prior notice).

      (e) In the event of (i) the incapacity of, or termination of employment
with Greenhill (whether due to death, resignation or otherwise) of both Robert
Niehaus and Robert Greenhill (the "Key Men") or (ii) the continued failure by
both Key Men to be actively involved in the affairs of the Partnership and the
Related Funds followed by a written demand by a Limited Partner or a limited
partner of a Related Fund to the General Partner for substantial performance
where the Key Men have unreasonably failed during the 30-day period following
receipt of such written demand to have cured such failure, then the Limited
Partners and limited partners of the Related Funds may elect to terminate the
Commitment Period at any time thereafter upon the affirmative vote of Limited
Partners (other than Defaulting Investors and any limited partner who is a
managing director, senior advisor, officer, employee or Affiliate of Greenhill
or the General Partner) and limited partners of the Related Funds (other than
defaulting partners and any limited partner who is a managing director, senior
advisor, officer or employee of Greenhill or the General Partner or any
Affiliate of such persons) having capital commitments representing in the
aggregate at least 66 2/3% of the Overall Capital. The General Partner will
promptly notify the Limited Partners of the incapacity of, or termination of
employment with Greenhill of, either of the Key Men.

      SECTION 5.02. Drawdown Procedures. (a) Generally. Each Investor shall make
Capital Contributions in such amounts and at such times as the General Partner
shall specify in notices ("Drawdown Notices") delivered from time to time to
such Investor. All Partnership Capital Contributions shall be paid to the
Partnership in immediately available funds in U.S. dollars by 11:00 A.M. (New
York time) on the date specified in the applicable Drawdown Notice. All Parallel
Capital Contributions shall be paid to the Person and the account and at the
time specified in the applicable Drawdown Notice (it being understood that
payment of Parallel Capital Contributions shall not constitute cash
contributions to the Partnership and shall not be paid to any account of the
Partnership). Partnership Capital Contributions may include amounts that the
General Partner determines, in its discretion, are necessary or desirable for
Temporary Cash Funds or to establish reserves in respect of Partnership
Investments or Partnership Expenses. Parallel Capital Contributions may include
amounts

                                       28

that the General Partner determines, in its discretion, are necessary or
desirable to establish reserves in respect of Parallel Investments or Parallel
Investment Expenses.

      The General Partner shall make Capital Contributions in such amounts as
hereinafter set forth in this Article 5 and at the same times and in the same
manner as the Investors who are required to make related Capital Contributions.

      (b) Regular Drawdowns.

            (i) Drawdown Notices. Except as otherwise provided in Section
      5.02(c), each Drawdown Notice for a Drawdown shall specify:

                  (A) the manner in which, and the expected date on which, such
            Drawdown is to be applied;

                  (B) if all or any portion of such Drawdown is to be applied to
            make one or more Investments, with respect to each proposed
            Investment, (w) a general description of the business of the Person
            that is, directly or indirectly, the subject of such proposed
            Investment, (x) the Investment Drawdown Amount in respect of such
            Investment, (y) whether such proposed Investment is in equity
            securities or equity-related securities (including preferred equity,
            convertible debt or similar securities) or debt securities, and (z)
            whether the Capital Contribution of such Investor in respect of such
            Investment is to be applied in respect of a Partnership Investment
            (and if so, whether directly or through a Partnership Investment
            Vehicle) or a Parallel Investment (and if so, whether directly or
            through a Parallel Investment Vehicle) or if all or any portion of
            such Drawdown is to be held as Temporary Cash Funds, the Investment
            Drawdown Amount related thereto;

                  (C) if all or any portion of such Drawdown is to be applied in
            respect of any Expenses, the Expenses Drawdown Amount;

                  (D) the required Capital Contribution to be made by such
            Investor (which shall be equal to the sum of such Investor's share
            (determined pursuant to Section 5.02(b)(ii)) of each Investment
            Drawdown Amount or Temporary Cash Funds and such Investor's share
            (determined pursuant to Section 5.02(b)(iii)) of the Expenses
            Drawdown Amount;

                  (E) the date (the "Drawdown Date") on which such Capital
            Contribution is due, which will be at least 10 calendar days from
            and including the date of delivery of the Drawdown Notice; and

                                       29

                  (F) the Person and the account to which such Capital
            Contribution shall be paid.

            (ii) Amount of Required Capital Contribution in Respect of
      Investments. (A) Subject to Sections 3.03(c) and 5.04, with respect to
      each Investment covered by any Drawdown and with respect to any Temporary
      Cash Funds, the General Partner and each Investor shall be required to
      make a Capital Contribution equal to the product of (x) such Person's
      Available Commitment Percentage multiplied by (y) the Investment Drawdown
      Amount in respect of such Investment or Temporary Cash Funds. The General
      Partner may in its discretion utilize each Partner's previous Capital
      Contributions in respect of Temporary Cash Funds to satisfy all or a
      portion of the Investment Drawdown Amount payable in connection with an
      Investment (or Partnership Expenses related thereto); provided that, if a
      Limited Partner is determined to be an Excused Investor with respect to
      such Investment, the Partners' Temporary Cash Funds shall be adjusted and
      reallocated to reflect the non-participation of the Excused Investor with
      respect to such Investment.

                  (B) With respect to any amount to be paid in connection with
            the exercise, conversion or exchange of any Convertible Securities,
            each Participating Investor in the Investment represented by such
            Convertible Securities shall be required to make a Capital
            Contribution equal to the product of (x) such amount required to be
            paid multiplied by (y) such Participating Investor's Investment
            Percentage in respect of such Investment.

                  (C) Subject to Sections 3.03(c) and 5.03, with respect to each
            Follow-On Investment covered by any Drawdown, each Participating
            Investor in the Original Investment to which such Follow-On
            Investment relates shall be required to make a Capital Contribution
            equal to the product of (x) such Participating Investor's Investment
            Percentage in respect of such Original Investment multiplied by (y)
            the Investment Drawdown Amount in respect of such Follow-On
            Investment.

                  (D) To the extent that any required Capital Contribution of
            any Participating Investor (calculated pursuant to Section
            5.02(b)(ii)(B) or 5.02(b)(ii)(C) without giving effect to the last
            sentence of Section 5.01(a)) exceeds such Participating Investor's
            then Available Capital Commitment, such Participating Investor may
            elect (but shall not be required) to increase its Capital Commitment
            by the amount of such excess. In the event that such Participating
            Investor elects not to or may not so increase its Capital
            Commitment, each of the other Participating Investors in such
            Investment shall be required to make a Capital Contribution equal to
            the product of (x) the amount of such excess multiplied by (y) such
            other Participating Investor's Available Commitment

                                       30

            Percentage (calculated without giving effect to the Available
            Capital Commitment of such Participating Investor who elects not to
            or may not so increase its Capital Commitment).

            (iii) Amount of Required Capital Contribution in Respect of
      Expenses. (A) With respect to the portion of the Expenses Drawdown Amount
      to be applied to pay Partnership Expenses, each Partner (including the
      General Partner) shall be required to make a Capital Contribution equal to
      the amount of such Partnership Expenses payable by such Partner as
      determined pursuant to Section 4.03.

                  (B) Subject to Section 7.02, with respect to any portion of
            the Expenses Drawdown Amount that is to be applied to pay Parallel
            Investment Expenses attributable to any Parallel Investment, each
            Participating Parallel Investor participating in such Parallel
            Investment shall be required to make a Capital Contribution equal to
            the amount of such Parallel Investment Expenses payable by such
            Parallel Investor as determined pursuant to Section 7.02(b).

      (c) Special Drawdowns. If, in connection with the making of any Investment
or the payment of any Investment Expense in respect of which a Drawdown Notice
has been delivered, the General Partner shall determine, in its discretion, that
it is necessary or desirable to increase the required Capital Contribution to be
made by any Investor in connection therewith, the General Partner shall deliver
an additional Drawdown Notice to such Investor amending the original Drawdown
Notice and specifying:

            (i) the amount of any increase in any Investment Drawdown Amount or
      in the Expenses Drawdown Amount, as the case may be;

            (ii) the amount of the increase in the required Capital Contribution
      to be made by such Investor;

            (iii) the Drawdown Date with respect to the amount of the increase
      in the required Capital Contribution if different from the Drawdown Date
      specified in the original Drawdown Notice; provided that the Drawdown Date
      with respect to the amount of such increase shall be at least two Business
      Days after delivery of such additional Drawdown Notice; and

            (iv) the reason for such increase.

      Any increase in the required Capital Contribution of any Investor pursuant
to Section 5.03 or 5.04 shall be calculated in the manner set forth therein. Any
increase in the required Capital Contribution of the General Partner and each
Investor due to an increase in any Investment Drawdown Amount or the Expenses
Drawdown Amount, as the case may be, specified in the original Drawdown

                                       31

Notice shall be calculated in accordance with Section 5.02(b) (after giving
effect to Sections 5.03 and 5.04, as appropriate) with respect to the amount of
such increase.

      SECTION 5.03. Excuse Procedure. (a) Any Investor may be excused from
making all or a portion of any required Capital Contribution in respect of any
Investment if: (i) not later than two Business Days after the date of delivery
of the applicable Drawdown Notice (or such later time as the General Partner
shall in its discretion determine), the General Partner shall have received a
notice from such Investor stating that it seeks to be excused from making such
Investment pursuant to this Section 5.03(a) and (ii) not later than five
Business Days after the date of delivery of the applicable Drawdown Notice (or
such later time as the General Partner shall in its discretion determine), the
General Partner shall have received a written opinion (in form and substance
reasonably satisfactory to the General Partner) of Investor's counsel
(reasonably satisfactory to the General Partner, which counsel may be in-house
counsel so long as such in- house counsel is reasonably satisfactory to the
General Partner) to the effect that it is highly probable that the making of
such Capital Contribution by such Investor in respect of such Investment would
result in a violation of any law or regulation of the United States of America
or any State thereof or of any non-U.S. jurisdiction (other than any such
non-U.S. law or material regulation that violates, or the compliance with which
by Persons subject to the jurisdiction of the United States of America would
violate, any law or material regulation of the United States of America)
(including any "prohibited transaction" as defined in ERISA or the Code), in any
such case applicable to such Investor or to the Partnership. Such opinion shall
also indicate whether (and, if so, at what reduced amount) such Investor could
make a smaller Capital Contribution in respect of such Investment that would not
result in such a violation. For purposes of ascertaining whether an Investor may
be excused from making a Capital Contribution pursuant to this Section 5.03(a),
the General Partner shall, as promptly as reasonably practicable, provide such
information about the proposed Investment as such Investor may reasonably
request.

      (b) An Investor shall be excused from making and shall not be permitted to
make all or a portion of any required Capital Contribution in respect of any
Investment if the General Partner delivers a written notice to such Investor
that the making of such Capital Contribution or portion thereof might have a
Material Adverse Effect. Any Capital Contribution by such Investor might have a
"Material Adverse Effect" if:

            (i) the General Partner, in its discretion, determines that (A) such
      Capital Contribution or portion thereof is likely, when taken by itself or
      together with other Capital Contributions of such Investor or of the
      General Partner and any other Investors:

                  (x) to result in a violation of any law or regulation of the
            United States of America or any State thereof or of any non-U.S.
            jurisdiction (other than any such non-U.S. law or regulation that
            violates, or the compliance with which by Persons subject to the
            jurisdiction of the United States of America would violate, any law
            or regulation of

                                       32

            the United States of America) (and the General Partner shall have
            received a written opinion of counsel to such effect); or

                  (y) to subject the Person that is, directly or indirectly, the
            subject of such proposed Investment, the Partnership, any
            Partnership Investment Vehicle, any Parallel Investment Vehicle, any
            Parallel Investor or any Related Fund to any regulatory or other
            legal requirements to which it would not otherwise have been subject
            and compliance with which is materially burdensome, or to increase
            materially the burden of complying with applicable regulatory or
            other legal requirements beyond the burden that would otherwise have
            existed (and the General Partner shall have received a written
            opinion of counsel as to the applicability of such regulatory or
            other legal requirements);

      and (B) in either case, such result should be avoided; or

                  (ii) the General Partner determines, in its reasonable
            discretion, that such Investor should not participate in such
            Investment because either (A) such Investor has, after being
            admitted to the Partnership, been convicted in a criminal proceeding
            (excluding misdemeanors), or was or is subject to a judgment, decree
            or final order enjoining future violations of, or prohibiting
            activities subject to, securities laws of the United States of
            America or any State thereof or of any non-U.S. jurisdiction or was
            or is subject to a finding as to any violation of such laws, in each
            case in a proceeding before a judicial or administrative body, or
            (B) participation by such Investor in such Investment would
            otherwise have a material adverse effect on the Person that is,
            directly or indirectly, the subject of the proposed Investment, the
            Partnership, any Partnership Investment Vehicle, any Parallel
            Investment Vehicle, any Parallel Investor, the General Partner, any
            Related Fund, the Manager, Greenhill or any of their respective
            Affiliates.

            The General Partner shall not be liable to any Investor or the
      Partnership for any failure to permit or require an Investor to be excused
      from making all or a portion of any required Capital Contribution pursuant
      to this Section 5.03(b), except for liability primarily attributable to
      the General Partner's gross negligence or bad faith.

            (c) Any Capital Contribution as to which an Investor is excused
      shall in no way affect such Investor's Available Capital Commitment, and
      any such excuse shall not affect such Investor's obligation to make other
      Capital Contributions.

            (d) If any Investor is excused from making all or a portion of any
      required Capital Contribution in respect of any Investment pursuant to
      this Section 5.03, the General Partner may,

                                       33

      in its discretion, take any or all of the following actions with respect
      to the amount that is excused and remains to be funded:

            (i) increase the required Capital Contributions of other Investors;

            (ii) obtain the agreement of one or more Investors to increase their
      respective Capital Contributions or of any third party or parties to cover
      such amount; or

            (iii) increase its own Capital Contribution.

      If the General Partner elects to take the action specified in Section
5.03(d)(i) with respect to any portion of the amount that is excused, the
General Partner shall deliver an additional Drawdown Notice in accordance with
Section 5.02(c) to each Investor who is not an Excused Investor in respect of
the applicable Investment, and the required Capital Contribution of each such
Investor shall be increased by an amount equal to the product of (A) such
Investor's Available Commitment Percentage (calculated (x) after giving effect
to the Capital Contributions specified in any prior Drawdown Notice and (y)
without giving effect to the Available Capital Commitment of the General Partner
and each Investor who is an Excused Investor in respect of such Investment)
multiplied by (B) the applicable portion of the Capital Contribution that
remains to be funded; provided that (I) if (but only to the extent) necessary to
address tax or regulatory considerations applicable to, or arising in connection
with, the applicable Investment, the General Partner may, in its discretion,
require that such applicable portion of the Capital Contribution be funded by
Capital Contributions made only by the Investors in one or more Investment
Portions with respect to such Investment that are not affected by such
accounting, tax or regulatory considerations, pro rata in proportion to their
Available Commitment Percentages (calculated (1) after giving effect to the
Capital Contributions specified in any prior Drawdown Notice and (2) without
giving effect to the Available Capital Commitment of the General Partner, each
Investor who is an Excused Investor in respect of such Investment, and the
Investors in any Investment Portion that are affected by such accounting, tax or
regulatory considerations) and (II) in the event that an Investor is excused
pursuant to this Section 5.03, no other Investor shall be required to make a
Capital Contribution in excess of 130% of the Capital Contribution that would
otherwise have been required from such Investor but for the provisions of this
Section 5.03(d) and Section 5.04(e).

      SECTION 5.04. Default by Investors. (a) Each of the General Partner and
each Investor agree that payment of its required Capital Contributions when due
is of the essence, that any Default by any Investor would cause injury to the
Partnership and to the General Partner and the other Investors and that the
amount of damages caused by any such injury would be extremely difficult to
calculate. Accordingly, if at any time an Investor shall Default, the amount of
such Default (the "Default Amount") shall accrue interest commencing on the
Drawdown Date

                                       34

at the lesser of (i) a rate per annum equal to the LIBOR plus 7% and (ii) the
maximum rate permitted by applicable law. Interest paid or otherwise recovered
on the Default Amount shall be allocated and distributed to the non- Defaulting
Investors.

      Upon the occurrence of any Default, the General Partner shall promptly
notify the Investor who has committed such Default of the occurrence of such
Default. Upon the occurrence of any Event of Default, the General Partner shall
promptly notify all Investors of the occurrence of such Event of Default.

      (b) Upon the occurrence of an Event of Default, the General Partner, in
its sole discretion, may:

            (i) cause the Defaulting Investor to forfeit all or any portion of
      distributions from the Partnership made or to be made after such Event of
      Default that relate to any Investments in respect of which such Investor
      made Capital Contributions prior to such Event of Default;

            (ii) if applicable, with respect to any distributions made or to be
      made after such Event of Default that relates to any Parallel Investment
      in respect of which the Defaulting Investor made a Capital Contribution
      prior to such Event of Default, cause the agreement governing such
      Parallel Investment to contain provisions substantially to the effect of
      clause (i) above;

            (iii) cause distributions that would otherwise be made to the
      Defaulting Investor to be credited against the Default Amount pursuant to
      Section 6.05;

            (iv) cause the Defaulting Investor to forfeit its representation, if
      any, on the LP Advisory Committee;

            (v) cause the Defaulting Investor to forfeit its right to
      participate in any Investments made after such Event of Default;

            (vi) cause a forced sale of the Defaulting Investor's interest in
      the Partnership to:

                  (A) any Investors who may wish to purchase such an interest,
            pro rata based on their respective Commitment Percentages at such
            time at the lesser of (x) an amount equal to 75% of the aggregate
            Capital Contributions made by the Defaulting Investor to the
            Partnership (net of any Capital Contributions previously returned to
            such Defaulting

                                       35

            Investor and distributions made to such Defaulting Investor pursuant
            to this Agreement) and (y) such other price as the General Partner,
            in its sole discretion, shall determine to be fair and reasonable
            under the circumstances; or

                  (B) in the event no Investor is willing to purchase such an
            interest, to any Person, at such price as the General Partner, in
            its sole discretion, shall determine to be fair and reasonable under
            the circumstances;

            (vii) cause a forced sale of the Defaulting Investor's interest in a
      Parallel Investment Vehicle to:

                  (A) any Investors who may wish to purchase such an interest,
            pro rata based on their respective Commitment Percentages at such
            time at the lesser of (x) an amount equal to 75% of the aggregate
            Capital Contributions made by the Defaulting Investor to such
            Parallel Investment Vehicle (net of any Capital Contributions
            previously returned to such Defaulting Investor and distributions
            made to such Defaulting Investor pursuant to the agreement governing
            the Parallel Investment Vehicle) and (y) such other price as the
            General Partner, in its sole discretion, shall determined to be fair
            and reasonable under the circumstances; or

                  (B) in the event no Investor is willing to purchase such an
            interest, to any Person, at such price as the General Partner, in
            its sole discretion, shall determined to be fair and reasonable
            under the circumstances; and

            (viii) institute proceedings to recover the Default Amount.

      (c) Upon the occurrence of any Event of Default in connection with any
Drawdown to be applied to make an Investment, the General Partner may, in its
discretion, take any or all of the following actions with respect to the amount
in default that remains to be funded:

            (i) increase the required Capital Contributions of other Investors;

            (ii) obtain the agreement of one or more Investors to increase their
      respective Capital Contributions or of a third party or parties to cover
      such amount;

            (iii) increase its own Capital Contribution; or

            (iv) borrow funds in accordance with Section 2.04.

                                       36

      (d) Upon the occurrence of any Event of Default in connection with a
Drawdown to be applied to pay Partnership Expenses, the General Partner may, in
its discretion, increase the required Capital Contributions of the other Limited
Partners with respect to the amount in default that remains to be funded.

      Upon the occurrence of any Event of Default in connection with a Drawdown
to be applied to pay Parallel Investment Expenses with respect to a Parallel
Investment, the General Partner may, in its discretion, increase the required
Capital Contributions of other Participating Parallel Investors with respect to
the amount in default that remains to be funded.

      (e) If the General Partner elects to take the action specified in Section
5.04(c)(i) or Section 5.04(d) with respect to any portion of the amount that is
in default in respect of the applicable Investment or Expense, as the case may
be, the General Partner shall deliver an additional Drawdown Notice in
accordance with Section 5.02(c) to the Investors who are required to make
Capital Contributions in respect of such Investment or Expense (other than any
Defaulting Investor with respect to the Investment or Expense, as the case may
be, in respect of which the Event of Default arose and any Excused Investor with
respect to such Investment, if applicable), and the required Capital
Contribution of each such Investor shall be increased by an amount calculated
(without giving effect to any Investor who is not such an Investor) with respect
to the amount that remains to be funded in accordance with Section 5.02(b);
provided that (i) with respect to a Default in connection with a Capital
Contribution required in respect of a proposed Investment, if (but only to the
extent) necessary to address accounting, tax or regulatory considerations
applicable to, or arising in connection with, such proposed Investment, the
General Partner may, in its discretion, require that such applicable portion of
the Capital Contribution be funded by Capital Contributions made only by the
Investors in one or more Investment Portions with respect to such Investment
that are not affected by such accounting, tax or regulatory considerations, pro
rata in proportion to their Available Commitment Percentages (calculated (i)
after giving effect to the Capital Contributions specified in any prior Drawdown
Notice and (ii) without giving effect to the Available Capital Commitment of the
General Partner, each Investor who is an Excused Investor in respect of such
Investment, and the Investors in any Investment Portion that are affected by
such accounting, tax or regulatory considerations) and (ii) no other Investor
shall be required to make a Capital Contribution in excess of 130% of the
Capital Contribution that would otherwise have been required from such Investor
but for the provisions of Section 5.03(d) and this Section 5.04(e).

      (f) Subject to Sections 5.04(c) and 5.04(d), the General Partner may take
either or both of the following actions in respect of the Available Capital
Commitment of any Defaulting Investor:

                                       37

            (i) seek commitments of capital from additional investors (which may
      in the discretion of the General Partner include existing Limited
      Partners) up to the amount of the Defaulting Investor's Available Capital
      Commitment. If any such commitment is received from any existing Limited
      Partner, such Limited Partner's Capital Commitment and Available Capital
      Commitment shall be increased accordingly. If any such commitment is
      received from an investor that is not an existing Limited Partner, such
      investor shall, after executing such instruments and delivering such
      opinions and other documents as are in form and substance satisfactory to
      the General Partner, be admitted to the Partnership as a Substituted
      Limited Partner and shown as such on the books and records of the
      Partnership and shall be deemed to have a Capital Commitment and an
      Available Capital Commitment equal to the commitment for which such
      investor has subscribed. After the appropriate adjustment of the Capital
      Commitment and the Available Capital Commitment of the Limited Partner or
      admission of the Substituted Limited Partner, the Capital Commitment and
      Available Capital Commitment of the Defaulting Investor shall be decreased
      accordingly; and

            (ii) reduce or cancel the Available Capital Commitment of the
      Defaulting Investor on such terms as the General Partner determines in its
      discretion (which may include leaving such Defaulting Investor obligated
      to make Capital Contributions with respect to Partnership Expenses and/or,
      if applicable, Parallel Investment Expenses up to the amount of such
      Partner's Available Capital Commitment immediately prior to the time such
      Available Capital Commitment is so reduced or canceled).

      (g) The rights and remedies referred to in this Section 5.04 shall be in
addition to, and not in limitation of, any other rights available to the General
Partner or the Partnership under this Agreement or at law or in equity. An Event
of Default by any Investor in respect of any Capital Contribution shall not
relieve any other Investor of its obligation to make Capital Contributions under
this Agreement. In addition, unless the Available Capital Commitment of any
Defaulting Investor is decreased to zero pursuant to Section 5.04(f), an Event
of Default by such Defaulting Investor shall not relieve such Investor of its
obligation to make Capital Contributions subsequent to such Event of Default.

      SECTION 5.05. Certain Exclusion Circumstances. (a) If, at any time during
the term of the Partnership, the General Partner reasonably determines that any
further participation by a Limited Partner in the Partnership's affairs would be
materially detrimental to the business or commercial reputation of any Portfolio
Company, the Partnership, the other Limited Partners, the General Partner,
Greenhill or any of their respective Affiliates, the General Partner may, in its
discretion, (i) cancel the Available Capital Commitment of such Limited Partner
on such terms as the General Partner determines in its discretion (which may
include leaving such Limited Partner obligated to make Capital Contributions
with respect to Partnership Expenses or, if applicable,

                                       38

Parallel Investment Expenses up to the amount of such Partner's Available
Capital Commitment immediately prior to the time such Available Capital
Commitment is so canceled) or (ii) exclude such Limited Partner (including, if
applicable, as a Parallel Investor) from participation in one or more future
Investments.

      (b) In the circumstances described in Section 5.05(a), to the extent
determined appropriate by the General Partner in its discretion, (i) such
Limited Partner shall cease to have the right, pursuant to this Agreement and
the Delaware Act, to obtain information regarding the Partnership and its
affairs other than such information as the General Partner in its reasonable
discretion deems necessary for such Limited Partner to monitor its existing
interest in the Partnership (which shall include and may be limited to the
information furnished to such Limited Partner pursuant to Article 8), (ii) such
Limited Partner shall not be entitled to vote, and such Limited Partner's
Capital Commitment or Invested Capital, as the case may be, shall be disregarded
(in the same manner as with respect to the General Partner or any Defaulting
Investor pursuant to Section 13.02(b)), in connection with any vote or approval
of the Limited Partners sought pursuant to Section 10.02, 11.01(a), 13.01
(except Section 13.01(a)(ii)), 13.02 or any other provision of this Agreement,
except as required by applicable law and unless any such vote or approval has a
material adverse effect on such Limited Partner's interests in Investments
existing at the time of such action by the General Partner pursuant to clause
(a) or (b) above, and (iii) such Limited Partner shall cease to have the right
to attend meetings of the LP Advisory Committee called by the General Partner
pursuant to Section 2.10. Any action pursuant to clause (a) or (b) above shall
have no effect on (x) such Limited Partner's interests in, and, except as
otherwise specifically provided in the immediately preceding sentence, rights
and obligations with respect to, Investments existing at the time of such
action, or (y) except as otherwise specifically provided in the immediately
preceding sentence, such Limited Partner's rights and obligations under this
Agreement, including its rights under Section 13.01 and its obligations under
Section 2.08. Any such action shall not constitute a withdrawal of such Limited
Partner from the Partnership within the meaning of the Delaware Act.

                                    ARTICLE 6
                  DISTRIBUTIONS; ALLOCATIONS; CAPITAL ACCOUNTS

      SECTION 6.01. Distributions Generally. Subject to the provisions of
Section 5.04 and Section 10.04, distributions shall be made in accordance with
this Article 6. Except as expressly set forth below, all calculations with
respect to distributions shall be made on a Partnership Investment by
Partnership Investment, and Participating Investor by Participating Investor,
basis. It is understood that the provisions set forth in this Article 6 shall
apply to all Partnership Investments made by the Partnership (other than
Parallel Investments, the terms of which are

                                       39

generally described in Article 7) and that, in making any determinations with
respect to any Investor pursuant to this Article 6 or Section 10.04 in
connection with such Partnership Investments, the performance of all Parallel
Investments shall be taken into account as if such Parallel Investments were
Partnership Investments made by the Partnership. Without limiting the generality
of the foregoing, such determinations shall, if appropriate, take into account
(i) the amount of such Investor's Invested Capital in each Parallel Investment,
and (ii) any amount paid or payable to the General Partner based upon the
performance of each Parallel Investment.

      SECTION 6.02. Distributions of Proceeds of Partnership Investments.
Subject to Section 6.03 and Section 6.05, each Participating Investor's
Investment Portion Percentage of any Proceeds from any Investment Portion of a
Partnership Investment made pursuant to this Agreement shall be distributed to
such Participating Investor.

      SECTION 6.03. Other Income. (a) Notwithstanding the provisions set forth
in Section 6.02, if the Partnership realizes any Transaction Fees, such
Transaction Fees shall be allocated and distributed to the Partners pro rata in
accordance with their Capital Commitments.

      (b) Subject to Section 10.04, all other items of income of the Partnership
that are not distributed pursuant to any other provision of this Article 6 shall
be distributed to the Partners pro rata in accordance with their Capital
Commitments (or such other allocation as the General Partner determines is
appropriate in its discretion); provided that income earned pursuant to Section
2.13 shall be distributed to the Partners in proportion to the amounts of cash
attributable to such Partners that gave rise to such income.

      SECTION 6.04. Tax Distributions. Notwithstanding the foregoing provisions
of this Article 6, the General Partner may, in its discretion, cause the
Partnership to make distributions in cash to each Partner equal to the Tax
Percentage of the net taxable income and gain allocated to such Partner in
respect of the prior year. For purposes of calculating net taxable income and
gain under this Section 6.04, each item of income, gain, loss, deduction and
credit of the Partnership shall be allocated among the Partners as nearly as
possible in the same manner as the corresponding item of income, expense, gain
or loss is allocated pursuant to the other provisions of this Article 6,
provided that no deduction shall be permitted in respect of any item whose
deductibility may, in the reasonable opinion of the General Partner, be subject
to limitations under Section 67 of the Code.

      SECTION 6.05. Other General Principles of Distribution.

      (a) Distributions of Cash. Subject to Section 10.04 and the remaining
provisions of this Section 6.05, (i) distributions of net cash Proceeds from the
Disposition of Investments shall be made as soon as reasonably practicable after
their receipt by the Partnership, and (ii)

                                       40

distributions of net cash Proceeds received by the Partnership, other than from
Dispositions of Investments, and distributions of income earned pursuant to
Section 2.13 shall be distributed as deemed appropriate by the General Partner
to Partners, but in no event less than annually. All distributions pursuant to
this Section 6.05(a) shall be made in immediately available funds in U.S.
dollars, except to the extent that distributions in U.S. dollars would be
illegal or impracticable under applicable law, in which case, to such extent,
distributions shall be made in the currency in which cash is received by the
Partnership.

      (b) Distributions in Kind. The General Partner generally intends to make
distributions in cash; provided that the General Partner may distribute
securities or other property if the General Partner reasonably believes that
such distribution in kind is in the best interest of the Partnership. Prior to
the dissolution of the Partnership, the Partnership shall not, without the
approval of the LP Advisory Committee, make any distributions in kind of
securities unless such securities are Marketable Securities. In connection with
the dissolution of the Partnership, subject to Section 10.04, the Partnership
may distribute in kind any securities (whether or not Marketable Securities) or
other property constituting all or any portion of a Partnership Investment in
such amounts as the General Partner shall in its discretion determine. Subject
to Article 7, in any distribution of property in kind, the General Partner shall
not discriminate among the Limited Partners in respect of such Partnership
Investment but shall in any such distribution (i) distribute to the applicable
Limited Partners property of the same type and tax basis and (ii) if cash and
property in kind are to be distributed simultaneously in respect of any
Partnership Investment, distribute cash and property in kind in the same
proportion to each such Limited Partner; provided that, to the extent necessary
to address regulatory or other similar considerations, the General Partner may
distribute such cash and property in kind in different proportions; and provided
further that the General Partner may make distributions to itself of property in
kind in lieu of cash. For purposes of allocations pursuant to Section 6.08, (i)
Marketable Securities shall be valued at their trading price on the principal
securities exchange on which such securities were traded at the close of the
trading day immediately prior to such distribution, or if such securities are
not primarily traded on a securities exchange, their closing bid prices as shown
by the National Association of Securities Dealers Automated Quotation System or
comparable established over-the-counter trading system on the trading day
immediately prior to such distribution, and adjusted, if appropriate, taking
into account any factors which are customarily taken into account in determining
whether the fair value of the securities is greater or less than the market
price and (ii) all other property to be distributed in kind shall be valued at
the fair market value thereof by the General Partner on a date as near as
reasonably practicable to the date of notice of such distribution. The General
Partner and the LP Advisory Committee will consult each other with a view to
agreeing upon the valuation of any property to be distributed in kind that is
not Marketable Securities but, in any event, the LP Advisory Committee shall
have the right, exercisable within 7 days of receipt of the General Partner's
proposed valuation, to

                                       41

require the General Partner to appoint an independent party to determine the
valuation of such securities.

      If any Investor notifies the General Partner (or other liquidator
described in Section 10.03) that such Investor is prohibited by applicable law
or regulation from holding directly the property to be distributed in kind or
the holding of such property by such Investor would have a material adverse
effect on such Investor, subject to compliance with applicable law, such
Investor may designate any other Person to receive such distribution or the
General Partner (or such liquidator) shall, in lieu of making such distribution
in kind to such Investor and to the extent permitted by applicable law, use its
reasonable efforts to sell such property on such Investor's behalf on terms
acceptable to such Investor and, upon such sale, the General Partner shall
promptly distribute to such Investor the net proceeds of such sale. The amount
of such net proceeds received in any such sale shall not affect the value of
such property for purposes of any calculation under Article 6 or Article 10,
which value for purposes of Article 6 or Article 10 shall be determined pursuant
to Section 6.05(b) or Section 10.04.

      (c) Withholding of Certain Amounts. Notwithstanding anything else
contained in this Agreement, the General Partner may, in its discretion,
withhold from any distribution of cash or property in kind to any Investor
pursuant to this Agreement, the following amounts:

            (i) any amounts due from such Investor to the Partnership or to the
      General Partner pursuant to this Agreement to the extent not otherwise
      paid (including, without limitation, Default Amounts); and

            (ii) any amounts required to pay, or to reimburse (on a net
      after-tax basis) any Indemnified Person for the payment of, any taxes and
      related expenses that the General Partner in good faith determines to be
      properly attributable to such Investor (including, without limitation,
      withholding taxes and interest, penalties, additions to tax and expenses
      described in the second paragraph of Section 9.01(b) incurred in respect
      thereof).

      Any amounts so withheld pursuant to this Section 6.05(c) shall be applied
by the General Partner to discharge the obligation in respect of which such
amounts were withheld.

      (d) Treatment of Certain Amounts Withheld. Notwithstanding anything else
in this Agreement, all amounts withheld by the General Partner pursuant to
Section 6.05(c) and all amounts that the General Partner determines in good
faith to be properly withheld or otherwise paid by any Person on behalf of any
Investor pursuant to the Code or any provision of any state, local or non-U.S.
tax law, shall be treated as if such amounts were realized and recognized by the
Partnership and distributed to such Investor pursuant to Section 6.02.

                                       42

      (e) Amounts Held in Reserve. In addition to the rights set forth in
Section 6.05(c), the General Partner shall have the right, in its discretion, to
withhold amounts otherwise distributable by the Partnership to the Investors in
order to maintain the Partnership in a sound financial and cash position and to
make such provision as the General Partner in its discretion deems necessary or
advisable for any and all liabilities and obligations, contingent or otherwise,
of the Partnership (other than the obligation of the Partnership to pay for the
purchase price of Partnership Investments) or if, following such distribution,
the aggregate of the balances on any Partner's Capital Account would be less
than zero.

      (f) Reinvestment of Dividends and Interest. Notwithstanding the foregoing
provisions of this Article 6, the General Partner, in its sole discretion, may
cause the Partnership to retain (and not to distribute to Investors) all or any
portion of any cash dividends or cash interest payments received by the
Partnership in connection with any Investment and to reinvest such Proceeds in
the Person or group of Affiliated Persons in which such Investment was made.

      (g) Delaware Act. Notwithstanding anything in this Agreement to the
contrary, the Partnership shall not make any distributions except to the extent
permitted under the Delaware Act.

      SECTION 6.06. Loans and Withdrawal of Capital. No Partner shall be
permitted to borrow, or to make an early withdrawal of, any portion of its
Capital Account.

      SECTION 6.07. Capital Accounts; Allocations.

      (a) Capital Accounts. There shall be established for each Partner on the
books and records of the Partnership a capital account (a "Capital Account"),
which shall initially be zero. The Capital Account of each Partner shall be:

            (i) credited with any Partnership Capital Contributions made by such
      Partner;

            (ii) credited with any allocations of income, profit or gain of the
      Partnership to such Partner;

            (iii) debited by the amount of cash (or the fair market value of
      other property as determined by the General Partner pursuant to Section
      6.05(b)) distributed by the Partnership to such Partner; and

            (iv) debited by any allocations of expense (other than any expense
      that should properly be included in the basis of any asset of the
      Partnership), deduction or loss of the Partnership to such Partner.

                                       43

      (b) Partnership Expenses. Partnership Expenses funded by or for the
account of any Partner in accordance with Section 4.03 shall be debited against
the Capital Account of such Partner. Amounts applied by the Partnership to fund
any Partner's share of any Partnership Investment Expense as contemplated by
Section 4.04(iv) shall be credited to the Capital Account of such Partner.

      (c) Interest Expenses. Interest expense and other expenses in respect of a
borrowing made pursuant to Section 2.04 shall be allocated to each Partner in
respect of whom such borrowing was made, pro rata in accordance with such
Partner's share of such borrowing, as determined by the General Partner.

      (d) Residual Allocations. Prior to dissolution of the Partnership, the
Partnership's remaining net income or net loss (after giving effect to
subparagraphs (a), (b) and (c) above) and each item of income, gain, loss,
deduction or expense included in the determination of such net income or net
loss shall be allocated among the Partners in a manner consistent with the
corresponding distributions made or to be made pursuant to this Article 6.

      (e) Allocations upon Dissolution. Upon the dissolution of the Partnership,
the realized gains and losses of the Partnership attributable to sales of assets
pursuant to Section 10.04 and the unrealized gains and losses of the assets to
be distributed pursuant to Section 10.04 shall be allocated among the Partners
in a manner consistent with the distribution provisions of this Article 6.

      (f) Timing of Allocations on Dispositions of Partnership Investments. In
connection with the disposition of Partnership Investments, allocations of
profit and loss shall be made from time to time within any fiscal year to the
extent necessary to effect the intent of the distribution provisions of this
Article 6 and Article 10.

      (g) Qualified Income Offset. Notwithstanding anything else contained in
this Article 6, if any Partner has a deficit Capital Account for any fiscal
period as a result of any adjustment of the type described in Treasury
Regulation Section 1.704-1(b)(2)(ii)(d)(4) through (6), then the Partnership's
income and gain will be specially allocated to such Partner in an amount and
manner sufficient to eliminate such deficit as quickly as possible. Any special
allocation of items of income or gain pursuant to this paragraph shall be taken
into account in computing subsequent allocations pursuant to this Article 6 so
that the cumulative net amount of all items allocated to each Partner shall, to
the extent possible, be equal to the amount that would have been allocated to
such Partner if there had never been any allocation pursuant to this paragraph.

                                       44

      (h) Compliance with Applicable Regulations. It is intended that the
Capital Accounts will be maintained at all times in accordance with Section 704
of the Code and applicable Treasury regulations thereunder, and that the
provisions hereof relating to the Capital Accounts be interpreted in a manner
consistent therewith. The General Partner shall be authorized in its discretion
to make appropriate adjustments to the allocations of items to comply with
Section 704 of the Code or applicable Treasury regulations thereunder; provided
that no such change shall have an adverse effect upon the amount distributable
to any Partner hereunder.

      SECTION 6.08. Tax Allocations. For federal, state and local income tax
purposes, each item of income, gain, loss, deduction and credit of the
Partnership shall be allocated among the Partners as nearly as possible in the
same manner as the corresponding item of income, expense, gain or loss is
allocated pursuant to the other provisions of this Article 6.

                                    ARTICLE 7
                              PARALLEL INVESTMENTS

      SECTION 7.01. Parallel Investments Generally. (a) Pursuant to, and subject
to the limitations contained in, Section 3.03, the General Partner may structure
all or part of a Partnership Investment by any Investor (or group of Investors)
as a Parallel Investment outside the Partnership directly by such Investor (or
group of Investors) or indirectly through any Parallel Investment Vehicle. The
specific terms applicable to each Parallel Investment shall be set forth in an
agreement or agreements between the General Partner and the Parallel Investors
participating in such Parallel Investment, and shall be substantially similar to
those contained in this Agreement with respect to Partnership Investments made
by the Partnership including, mutatis mutandis, the provisions of Section
1.06(b), Article 6 and Section 10.04 with respect to the determination of the
distributions that the Investors are entitled to receive in respect of such
Parallel Investment based upon the performance of such Parallel Investment and
other Partnership Investments made pursuant to this Agreement. The terms of the
agreement or agreements referred to in the immediately preceding sentence shall
apply only to the particular Parallel Investment or Parallel Investments covered
by such agreement or agreements.

      (b) Notwithstanding anything in this Agreement to the contrary, including
the provisions of Section 7.01(a), the General Partner and the Investors
acknowledge and agree that (i) each Parallel Investment shall be made for the
sole benefit of the Participating Parallel Investors in respect of such Parallel
Investment (and not made for the benefit of the Partnership), (ii) no Parallel
Investment shall constitute or be deemed to be an asset of the Partnership for
any purpose and (iii) no creditor of the Partnership shall have any recourse or
claim against any Parallel Investment or be entitled reasonably to rely on the
existence of any

                                       45

Parallel Investment in extending credit to the Partnership. Without limiting the
generality of the foregoing, (A) no Parallel Investment shall be set forth on
the books and records of the Partnership or, except as otherwise required by
law, listed on the tax returns to be filed by the Partnership, and (B) the
Partnership shall not use any of its funds to acquire or otherwise make any
Parallel Investment.

      SECTION 7.02. Parallel Investment Expenses. (a) General Principle.
Notwithstanding any provision in this Agreement to the contrary, the General
Partner and the Investors acknowledge and agree that (i) no Parallel Investment
Expenses shall be incurred for the benefit of, or borne by, the Partnership,
(ii) Parallel Investment Expenses shall not constitute or be deemed to be
Partnership Expenses for any purpose and (iii) no creditor whose claims arise in
connection with any Parallel Investment shall have any recourse or claim against
the Partnership or any Partnership Investment by the Partnership or be entitled
reasonably to rely on the existence of the Partnership or any Partnership
Investment by the Partnership in extending credit to any Parallel Investor or
with respect to such Parallel Investment. Without limiting the generality of the
foregoing, (A) no Parallel Investment Expenses shall be set forth on the books
and records of the Partnership or, except as otherwise required by law, listed
on the tax returns to be filed by the Partnership and (B) the Partnership shall
not use any of its funds to pay or otherwise satisfy any Parallel Investment
Expenses.

      (b) Responsibility for Parallel Investment Expenses Among Parallel
Investors. The Partners agree that, as among the Parallel Investors,
responsibility for Parallel Investment Expenses will be determined as set forth
in this Section 7.02(b) and shall be paid out of the funds set forth in Section
7.02(c) at such time after such Parallel Investment Expenses arise as the
General Partner determines in its discretion:

            (i) subject to Section 7.02(b)(ii), any Parallel Investment Expenses
      attributable to any Parallel Investment shall be paid by the Participating
      Parallel Investors pro rata in accordance with their respective Investment
      Percentages in such Parallel Investment; and

            (ii) notwithstanding clause (i) above, the General Partner may
      calculate the contribution to be made by Participating Parallel Investors
      with respect to any Parallel Investment Expense on any other basis
      (including requiring certain, but not all, such Parallel Investors or
      other Investors to fund such Expense) if the General Partner reasonably
      determines that such other basis is clearly more equitable.

      (c) Sources of Funds for Payment by Parallel Investors of Parallel
Investment Expenses. Parallel Investment Expenses shall be paid by or on behalf
of the Parallel Investors to the extent provided in Section 7.02(b) through any
one or more of the following sources of funds, determined by the General Partner
in its discretion:

                                       46

            (i) Capital Contributions by the Parallel Investors in accordance
      with Article 5;

            (ii) the withholding, pursuant to the provisions of the agreement
      governing any Parallel Investment or Parallel Investment Vehicle, of
      amounts (whether realized through the sale of securities comprising
      Parallel Investments or otherwise) payable or distributable to the
      Parallel Investors;

            (iii) reserves set aside for the payment of such expenses pursuant
      to the provisions of the agreement governing any Parallel Investment or
      Parallel Investment Vehicle;

            (iv) amounts required to be contributed by the Parallel Investors
      pursuant to the provisions of the agreement governing any Parallel
      Investment or Parallel Investment Vehicle that correspond to Section 9.03,
      as contemplated by Section 9.04; or

            (v) in accordance with the last sentence of Section 7.02(a).

      SECTION 7.03. Parallel Investor Borrowings. The General Partner shall not
on behalf of any Parallel Investor, except in connection with the payment of any
Parallel Investment Expenses and subject to Section 2.04, (i) incur any
indebtedness for borrowed money, (ii) guarantee the indebtedness for borrowed
money of any Person or (iii) otherwise become contingently liable with respect
to any indebtedness for borrowed money of any Person.

      SECTION 7.04. Consequences upon Default. Upon any Event of Default by an
Investor, with respect to any Parallel Investment in which such Defaulting
Partner is a Participating Parallel Investor, the General Partner shall be
entitled to pursue any and all of the remedies set forth in Section 5.04. Each
Investor hereby agrees to do and to take any and all such further things and
actions, and to execute and deliver any and all such further agreements,
instruments and documents, as may be necessary or desirable to give effect to
this Section 7.04. Notwithstanding any such Event of Default, the General
Partner may, in its discretion, release such Partner from its obligations under
this Section 7.04 to the extent and on such terms as the General Partner
determines in its discretion.

                                       47

                                    ARTICLE 8
                           REPORTS TO LIMITED PARTNERS

      SECTION 8.01. Reports. (a) The books of account and records of the
Partnership shall be audited as of the end of each fiscal year by the
Partnership's independent public accountants. All reports provided to the
Limited Partners pursuant to this Section 8.01 shall be prepared in accordance
with U.S. generally accepted accounting principles, consistently applied,
including presentation of the fair value of Partnership Investments.

      The Partnership's independent public accountants shall initially be Ernst
& Young LLP. The General Partner may, in its discretion, for any fiscal year of
the Partnership after December 31, 2000, change the Partnership's independent
public accountants; provided that the Partnership's independent public
accountants selected by the General Partner after consultation with the LP
Advisory Committee shall be a nationally recognized independent certified public
accounting firm.

      (b) Not later than 60 days after the end of each fiscal quarter (other
than the fourth quarter), the General Partner shall prepare and mail to each
Person who was a Partner during such fiscal quarter an unaudited report setting
forth as of the end of such fiscal quarter:

            (i) a balance sheet of the Partnership as of the end of such fiscal
      quarter; and

            (ii) an income statement of the Partnership for such fiscal quarter.

      (c) Not later than 90 days after the end of each fiscal year, the General
Partner shall prepare, and shall mail to each Partner, a report audited by the
independent public accountants setting forth as of the end of such fiscal year:

            (i) a balance sheet of the Partnership as of the end of such fiscal
      year;

            (ii) an income statement of the Partnership for such fiscal year;

            (iii) a statement of the Partnership's capital for such year; and

            (iv) a statement in reasonable detail of adjustments to such
      Partner's Capital Account for such fiscal year, and a statement of such
      Partner's closing Capital Account balance for such fiscal year.

                                       48

      (d) In addition, not later than 60 days after the end of each fiscal
quarter, the General Partner shall prepare and mail to each Partner a report
setting forth as of the end of such fiscal quarter:

            (i) a list of the Partnership's current Partnership Investments and
      all current Parallel Investments;

            (ii) a summary description of new Partnership Investments made by
      the Partnership and new Parallel Investments made during such fiscal
      quarter; and

            (iii) a summary description of Partnership Investments and Parallel
      Investments disposed of during such fiscal quarter.

      (e) After the end of each fiscal year, the General Partner shall prepare
and send, or cause to be prepared and sent, as promptly as possible, and in any
event within 90 days of the close of the fiscal year (except to the extent that
delay is incurred on account of failure of any Portfolio Company to supply
necessary information in a timely manner), a federal income tax form K-1 for
each Partner, a copy of the Partnership's return filed for federal income tax
purposes and a report setting forth in sufficient detail such transactions
effected by the Partnership (and, if applicable, by such Partner as a Parallel
Investor) during such fiscal year as shall enable each Partner to prepare its
United States federal and state income tax returns, if any, and, if appropriate,
comparable materials to enable each Partner to prepare any necessary non-U.S.
income tax returns. The General Partner shall mail such materials to (i) each
Partner and (ii) each former Partner (or its successors, assigns, heirs or
personal representatives) who may require such information in preparing its
United States federal and state or non-U.S. income tax returns.

                                    ARTICLE 9
                         EXCULPATION AND INDEMNIFICATION

      SECTION 9.01. Exculpation and Indemnification. (a) No Indemnified Person
shall be liable to the Partnership or to the Partners for any losses, claims,
damages or liabilities arising from, related to, or in connection with this
Agreement or the Partnership's business or affairs (including any act or
omission by any Indemnified Person and any activity of the type or character
disclosed or contemplated in Section 2.05), except for any losses, claims,
damages or liabilities resulting from such Indemnified Person's gross negligence
or willful misconduct. The foregoing provision shall not affect the General
Partner's obligation to correct any allocations to the Capital Accounts of the
Partners pursuant to Section 6.07 or distributions to the Partners pursuant to
Section 6.02 or 6.03 if such allocations or distributions were not made in
accordance with this

                                       49

Agreement. In addition, no Indemnified Person shall be liable to the Partnership
or to the Partners with respect to the accuracy or completeness of any
information furnished by such Indemnified Person or any other Indemnified Person
regarding any Portfolio Company where such information is obtained from a third
party (including, without limitation, a Portfolio Company) and not prepared by
an Indemnified Person. Notwithstanding the foregoing provisions of this Section
9.01(a), no provision of this Agreement shall constitute a waiver or limitation
of any Limited Partner's rights under the U.S. federal securities laws.

      (b) The Partnership shall, to the fullest extent permitted by applicable
law, indemnify and hold harmless each Indemnified Person against any losses,
claims, damages or liabilities (other than Parallel Investment Expenses) arising
out of, related to or in connection with this Agreement or the Partnership's
business or affairs, except for any such losses, claims, damages or liabilities
resulting from such Indemnified Person's gross negligence or willful misconduct.
Subject to the immediately succeeding sentence, the Partnership will
periodically reimburse each Indemnified Person for all expenses (including fees
and expenses of counsel) as such expenses are incurred in connection with
investigating, preparing, pursuing or defending any Proceeding related to,
arising out of or in connection with this Agreement or the Partnership's
business or affairs whether or not pending or threatened and whether or not any
Indemnified Person is a party thereto; provided that such Indemnified Person
shall promptly repay to the Partnership the amount of any such reimbursed
expenses paid to it if it shall be judicially determined by judgment or order
not subject to further appeal or discretionary review that such Indemnified
Person is not entitled to be indemnified by the Partnership in connection with
such matter as provided in the exception contained in the immediately preceding
sentence. If for any reason (other than the gross negligence or willful
misconduct of such Indemnified Person) the foregoing indemnification is
unavailable to any Indemnified Person, or insufficient to hold it harmless, then
the Partnership shall contribute to the amount paid or payable by such
Indemnified Person as a result of such loss, claim, damage or liability in such
proportion as is appropriate to reflect the relative benefits received by the
Partnership, on the one hand, and such Indemnified Person, on the other hand,
or, if such allocation is not permitted by applicable law, to reflect not only
the relative benefits referred to above but also any other relevant equitable
considerations.

      Each Partner covenants for itself and its successors, assigns, heirs and
personal representatives that such Person will, at any time prior to or after
dissolution of the Partnership, whether before or after such Person's withdrawal
from the Partnership, pay to the Partnership or the General Partner on demand
any amount which the Partnership or the General Partner, as the case may be,
properly pays in respect of taxes (including withholding taxes) imposed upon
income of, or distributions in respect of Partnership Investments made to, such
Partner.

                                       50

      (c) Notwithstanding anything else contained in this Agreement, the
exculpation provisions under Section 9.01(a) and the reimbursement, indemnity
and contribution obligations of the Partnership under Section 9.01(b) (the
"Indemnification Obligations") shall:

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

            (ii) extend upon the same terms and conditions to the officers,
      directors, members, employees, Affiliates, stockholders, agents and
      representatives of each Indemnified Person;

            (iii) be binding upon and inure to the benefit of any successors,
      assigns, heirs and personal representatives of each Indemnified Person;
      and

            (iv) be limited to the sum of (x) the assets of the Partnership,
      plus (y) the amount of all Partners' aggregate Available Capital
      Commitments, plus (z) subject to Section 9.03, the aggregate amount of all
      distributions previously made by the Partnership to the Partners; provided
      that if such sum is insufficient to fulfill the Partnership's obligations
      under this Article 9, the General Partner may, in its discretion, seek to
      satisfy such obligation out of the assets of a Parallel Investment made
      pursuant to this Agreement.

      (d) To the extent that, at law or in equity, any Indemnified Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Partnership or to any Partner, the General Partner and any other Indemnified
Person acting in connection with the Partnership's affairs shall not be liable
to the Partnership or to any Partner for its good faith reliance on the
provisions of this Agreement. The provisions of this Agreement, to the extent
that they restrict the duties and liabilities or rights and powers of any
Indemnified Person otherwise existing at law or in equity, are agreed by the
Partners to replace such other duties, liabilities, rights and powers of such
Indemnified Person.

      (e) The General Partner and the Investors acknowledge and agree that the
terms of each Parallel Investment or Parallel Investment Vehicle shall include
provisions applicable to such Parallel Investment or Parallel Investment Vehicle
substantially identical to the provisions of this Section 9.01 and Section 9.02.

      (f) The General Partner may cause the Partnership to purchase and maintain
insurance coverage reasonably satisfactory to the General Partner that provides
the Partnership with coverage with respect to losses, claims, damages,
liabilities and expenses that would otherwise be Indemnification Obligations.
The fees and expenses incurred in connection with obtaining and

                                       51

maintaining any such insurance policy or policies, including any commissions and
premiums, shall be Partnership Administrative Expenses.

      (g) With respect to any Indemnification Obligation that is also an
obligation of any Related Fund (a "Shared Obligation"), the General Partner and
the general partner of each Related Fund that is liable under such Shared
Obligation shall allocate any amounts due to any Person under such Shared
Obligation pro rata among the Partnership and such Related Funds in accordance
with the aggregate Capital Commitments of the Limited Partners and the limited
partners in the Related Funds.

      SECTION 9.02. Forum Selection. (a) To the fullest extent permitted by
applicable law, the General Partner and each Investor hereby agree that any
claim, action or proceeding by any Investor seeking any relief whatsoever
against any Indemnified Person based on, arising out of or in connection with
this Agreement or the Partnership's affairs shall be brought only in the federal
courts, or if federal court jurisdiction is unavailable in the state courts,
located in the State of Delaware or the State of New York, Borough of Manhattan,
and not in any other State or Federal court in the United States of America or
any court in any other country. The General Partner and each Investor
acknowledge that, in the event of any breach of this provision, the Indemnified
Persons have no adequate remedy at law and shall be entitled to injunctive
relief to enforce the terms of this Section 9.02.

      (b) EACH PARTNER HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO A TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

      SECTION 9.03. Return of Distributions. (a) Notwithstanding anything else
contained in this Agreement, if the Partnership incurs an Indemnification
Obligation and the amount of reserves, if any, specifically identified by the
Partnership with respect to such Indemnification Obligation is less than the
amount of such Indemnification Obligation, the General Partner may require each
Limited Partner to repay to the Partnership, at any time or from time to time,
whether before or after dissolution of the Partnership or before or after such
Person's withdrawal from the Partnership, in satisfaction of such Limited
Partner's share of such Indemnification Obligation, all or any portion of the
amount of the distributions previously made by the Partnership to such Limited
Partner to the extent of such Limited Partner's share of such Indemnification
Obligation; provided that no Partner shall be required to make a repayment of
any distributions pursuant to this Section 9.03(a) at any time after the third
anniversary of the date on which such distributions were made by the
Partnership, or to repay any amount which, together with all such amounts
previously repaid pursuant to this Section 9.03(a), would exceed the lesser of
(i) the total amount of distributions previously received by such Partner (or
the

                                       52

predecessor-in-interest to such Partner) from the Partnership and (ii) an amount
equal to 25% of such Partner's Capital Commitment.

      (b) To the extent that the remedies provided in Section 9.03(a) are
insufficient to hold any Indemnified Person harmless in connection with an
Indemnification Obligation of the Partnership, each Investor shall pay, in
satisfaction of such Investor's remaining share of such Indemnification
Obligation, to the Indemnified Persons, in such Investor's individual capacity,
at any time or from time to time, whether before or after the dissolution of the
Partnership or before or after such Investor's withdrawal from the Partnership,
all or any portion of the amount of distributions previously made to such
Investor in respect of Parallel Investments to the extent of such Investor's
remaining share of such Indemnification Obligation; provided that no Investor
shall be required to make a contribution pursuant to this Section 9.03(b) with
respect to any distributions at any time after the third anniversary of the date
on which such distributions were made by the Partnership, or to contribute any
amount which, together with all such amounts previously contributed pursuant to
this Section 9.03(b), would exceed the lesser of (i) the total amount of
distributions previously received by such Investor (or the
predecessor-in-interest to such Investor) with respect to Parallel Investments
and (ii) an amount equal to 25% of such Partner's Capital Commitment.

      (c) The provisions of this Section 9.03 shall be in addition to and not
affect the obligations of the Limited Partners under the Delaware Act or any
other provision of applicable law. Nothing in this Section 9.03 is intended to
expand the rights of Indemnified Parties to indemnification, contribution or
reimbursement under Section 9.01.

      SECTION 9.04. Parallel Investments. The Partners agree that the terms of
each Parallel Investment shall include provisions applicable to such Parallel
Investment substantially identical to the provisions of Section 9.01, Section
9.02 and Section 9.03.

                                   ARTICLE 10
                   DURATION AND DISSOLUTION OF THE PARTNERSHIP

      SECTION 10.01. Duration. The term of the Partnership shall continue until
June 30, 2010, unless the Partnership is sooner dissolved pursuant to Section
10.02; provided that, subject to Section 10.02, the General Partner may extend
the term of the Partnership for up to two additional successive one-year terms
following the expiration of such initial term, and provided further that the
General Partner may extend the term of the Partnership for the second of such
one-year terms only upon the approval of the Advisory Committee.

                                       53

      SECTION 10.02. Dissolution. Subject to the Delaware Act, the Partnership
shall be dissolved and its affairs shall be wound up upon the earliest of:

      (a) the expiration of the term of the Partnership provided in Section
10.01;

      (b) the written consent of the General Partner and the Required Limited
Partners to dissolve the Partnership, which consent shall not be effective
unless each Related Fund is also being concurrently dissolved;

      (c) a decision made by the General Partner, in its discretion after
consultation with counsel, to dissolve the Partnership because it has determined
in good faith that (i) changes in any applicable law or regulation would have a
material adverse effect on the continuation of the Partnership or (ii) such
action is necessary or desirable as provided in Section 2.03;

      (d) an event of withdrawal of the General Partner (within the meaning of
the Delaware Act) unless, (i) at the time there is at least one remaining
general partner of the Partnership and all remaining general partners shall
agree to continue the business of the Partnership without dissolution, or (ii)
if there is no remaining general partner of the Partnership, the Required
Limited Partners agree in writing or vote within 90 days of such event of
withdrawal to continue the business of the Partnership and to the appointment of
a successor general partner of the Partnership, effective as of the date of such
event;

      (e) the entry of a decree of judicial dissolution under Section 17-802 of
the Delaware Act;

      (f) at any time there are no limited partners of the Partnership, unless
the Partnership is continued in accordance with the Delaware Act.

      SECTION 10.03. Liquidation of Partnership. Upon dissolution, the
Partnership's business shall be liquidated in an orderly manner. Except as
provided in the immediately succeeding sentence, the General Partner shall be
the liquidator to wind up the affairs of the Partnership pursuant to this
Agreement. If there shall be no General Partner or if the Partnership shall be
dissolved pursuant to Section 10.02(d), the Limited Partners, upon the approval
of the Required Limited Partners, may approve one or more liquidators to act as
the liquidator in carrying out such liquidation. In performing its duties,
subject to the Delaware Act, the liquidator is authorized to sell, distribute,
exchange or otherwise dispose of the assets of the Partnership in any reasonable
manner that the liquidator shall determine to be in the best interest of the
Partners.

                                       54

      SECTION 10.04. Distribution Upon Dissolution of the Partnership. Upon
dissolution of the Partnership, the liquidator winding up the affairs of the
Partnership shall determine in its discretion which assets of the Partnership
shall be sold and which assets of the Partnership shall be retained for
distribution in kind to the Partners. Subject to Section 6.05(b), assets to be
distributed in kind shall be valued by the liquidator in its discretion. Subject
to the Delaware Act, after all liabilities of the Partnership have been
satisfied or duly provided for, the remaining assets of the Partnership shall be
distributed to the Partners pro rata in accordance with their positive Capital
Account balances, as adjusted in accordance with Article 6 (including, without
limitation, adjustments attributable to sales of assets pursuant to this Section
10.04 and adjustments to reflect unrealized gain or loss in the assets to be
distributed).

      (a) In the discretion of the liquidator, and subject to the Delaware Act,
a portion of the distributions that would otherwise be made to the General
Partner and the Limited Partners pursuant to this Section 10.04 may be:

            (i) distributed to a trust established for the benefit of the
      Partners for purposes of liquidating Partnership assets, collecting
      amounts owed to the Partnership, and paying any liabilities or obligations
      of the Partnership or the General Partner arising out of, or in connection
      with, this Agreement or the Partnership's affairs; or

            (ii) withheld, with respect to any Partner, to provide a reserve for
      the payment of such Partner's share of future Partnership Expenses;
      provided that such withheld amounts shall be distributed to the Partners
      as soon as the liquidator determines, in its discretion, that it is no
      longer necessary to retain such amounts.

      The assets of any trust established in connection with clause (i) above
shall be distributed to the Partners from time to time, in the discretion of the
liquidator, in the same proportions as the amount distributed to such trust by
the Partnership would otherwise have been distributed to the Partners pursuant
to this Agreement.

      (b) Each Partner shall look solely to the assets of the Partnership for
the return of such Partner's aggregate Invested Capital in Partnership
Investments, and no Partner shall have priority over any other Partner as to the
return of such Invested Capital.

      SECTION 10.05. Withdrawal, Death or Incompetency of a Limited Partner.
Except as otherwise provided in Article 12, a Limited Partner may not withdraw
from the Partnership prior to its dissolution and winding up. Upon the death or
incompetency of an individual Limited Partner, such Limited Partner shall not be
entitled to receive the fair value or his or her interest in the Partnership
under Section 17-604 of the Delaware Act. Upon the death or incompetency of an
individual Limited Partner, such Limited Partner's executor, administrator,
guardian,

                                       55

conservator or other legal representative may exercise all of such Limited
Partner's rights for the purpose of settling such Limited Partner's estate or
administering such Limited Partner's property, except that the General Partner
may reduce or cancel the Available Capital Commitment of such Limited Partner
(on such terms as the General Partner determines in its discretion (which may
include leaving such Limited Partner obligated to make Capital Contributions
with respect to Partnership Expenses and, if applicable, Parallel Investment
Expenses up to the amount of such Limited Partner's Available Capital Commitment
immediately prior to the time such Available Capital Commitment is so reduced or
canceled)); provided that following the death of a managing director, senior
advisor or employee of Greenhill who owns an investment vehicle which is a
Limited Partner, the General Partner may reduce or cancel the Available Capital
Commitment of such Limited Partner (on such terms as the General Partner
determines in its discretion (which may include leaving such Limited Partner
obligated to make Capital Contributions with respect to Partnership Expenses
and, if applicable, Parallel Investment Expenses up to the amount of such
Limited Partner's Available Capital Commitment immediately prior to the time
such Available Capital Commitment is so reduced or canceled)). Except as
expressly provided in this Agreement, no other event affecting a Limited Partner
(including bankruptcy or insolvency) shall affect its obligations under this
Agreement or affect the Partnership.

                                   ARTICLE 11
                  TRANSFERABILITY OF GENERAL PARTNER'S INTEREST

      SECTION 11.01. Transferability of General Partner's Interest. (a) Except
as otherwise provided herein, the General Partner may not, directly or
indirectly, sell, exchange, transfer, assign, pledge, hypothecate or otherwise
dispose of all or any portion of its interest in the Partnership (any such
direct or indirect sale, exchange, transfer, assignment, pledge, hypothecation,
swap or other disposition being herein collectively called "Transfers") to any
Person (other than to a successor-in-interest (by merger or otherwise) or
assignee that is an Affiliate of Greenhill, which Transfer may be made without
the approval of any other Partner) without the prior approval of Limited
Partners (other than Defaulting Investors) and limited partners of the Related
Funds (other than defaulting partners) representing at least 75% of the
aggregate Capital Commitments of all Limited Partners (other than Defaulting
Investors) and limited partners of the Related Funds (other than defaulting
partners) at such time. If the General Partner so determines in its discretion,
and any such prior approval of the Limited Partners (if required) so provides,
the General Partner may admit any Person to whom the General Partner proposes to
make such a Transfer as an additional general partner of the Partnership, and
such transferee shall be deemed admitted to the Partnership as a general partner
of the Partnership

                                       56

immediately prior to such Transfer and shall continue the business of the
Partnership without dissolution.

      (b) Except as otherwise provided in this Article 11, the General Partner
may not withdraw from the Partnership (within the meaning of the Delaware Act)
or be removed as general partner of the Partnership.

                                   ARTICLE 12
                 TRANSFERABILITY OF A LIMITED PARTNER'S INTEREST

      SECTION 12.01. Restrictions on Transfer. (a) Subject to Section 10.05, no
Transfer of all or any part of a Limited Partner's interest in the Partnership
may be made without the prior approval of the General Partner, which approval
may be granted or withheld by the General Partner in its discretion.

      (b) The foregoing provisions of this Section 12.01 shall not apply to any
Transfer by a Limited Partner of all or any part of such Limited Partner's
interest in the Partnership to an Affiliate of such Limited Partner.

      (c) Notwithstanding the provisions of Section 12.01(b), in no event may a
Limited Partner Transfer any portion of its interest in the Partnership nor may
a Substituted Limited Partner be admitted to the Partnership if such Transfer or
such admission would, in the judgment of the General Partner, cause a

market as defined in Treas. Reg. Section 1.7701-1(b), or recognize any Transfers

or otherwise recognizing the rights of such transferee.

and shown as such on the books and records of the Partnership, being hereinafter
called a "Substituted Limited Partner"). In addition, the transferring Limited

                                       57

Partner or such transferee shall indemnify the Partnership and the General
Partner in a manner satisfactory to the General Partner against any losses,
claims, damages or liabilities to which the Partnership or the General Partner
may become subject arising out of, related to or in connection with any false
representation or warranty made by, or breach or failure to comply with any
covenant or agreement of, such transferring Limited Partner or such transferee.

      SECTION 12.03. Recognition of Transfer; Substituted Limited Partners. (a)
No purchaser, assignee, or other recipient of all or any portion of a Limited
Partner's interest in the Partnership may be admitted to the Partnership as a
Substituted Limited Partner without the prior approval of the General Partner
(which may, in the General Partner's discretion, be withheld). If the General
Partner approves the admission of any Person to the Partnership as a Substituted
Limited Partner, such Person, as a condition to its admission as a Limited
Partner, shall execute and acknowledge such instruments (including a counterpart
of this Agreement), in form and substance satisfactory to the General Partner,
as the General Partner reasonably deems necessary or desirable to effectuate
such admission and to confirm the agreement of such Person to be bound by all
the terms and provisions of this Agreement with respect to the interest in the
Partnership acquired by such Person.

      (b) The Partnership shall not (subject to Section 10.05) recognize for any
purpose any purported Transfer of all or any part of a Limited Partner's
interest in the Partnership and no purchaser, assignee, transferee or other
recipient of all or any part of such interest shall become a Substituted Limited
Partner hereunder unless:

            (i) the provisions of Sections 12.01, 12.02 and 12.03(a) shall have
      been complied with;

            (ii) the General Partner shall have been furnished with the
      documents effecting such Transfer, in form reasonably satisfactory to the
      General Partner, executed and acknowledged by both the seller, assignor or
      transferor and the purchaser, assignee, transferee or other recipient;

            (iii) such purchaser, assignee, transferee or other recipient shall
      have represented that such Transfer was made in accordance with all
      applicable laws and regulations;

            (iv) all necessary governmental consents shall have been obtained in
      respect of such Transfer;

                                       58

            (v) the books and records of the Partnership shall have been changed
      (which change shall be made as promptly as practicable) to reflect the
      admission of such Substituted Limited Partner; and

            (vi) all necessary instruments reflecting such admission shall have
      been filed in each jurisdiction in which such filing is necessary in order
      to qualify the Partnership to conduct business or to preserve the limited
      liability of the Limited Partners.

      Upon the satisfaction of the conditions set forth in this Section 12.03,
any such purchaser, assignee, or other recipient shall become a Substituted
Limited Partner.

      SECTION 12.04. Transfers During a Fiscal Year. If any Transfer (other than
a pledge or hypothecation) of a Partner's interest in the Partnership shall
occur at any time other than the end of the Partnership's fiscal year, the
distributive shares of the various items of Partnership income, gain, loss, and
expense as computed for tax purposes and the related cash distributions shall be
allocated between the transferor and the transferee on such proper basis as the
transferor and the transferee shall agree consistent with applicable
requirements under Section 706 of the Code; provided that no such allocation
shall be effective unless (i) the transferor and the transferee shall have given
the Partnership written notice, prior to the effective date of such Transfer,
stating their agreement that such allocation shall be made on such proper basis,
(ii) the General Partner shall have consented to such allocation, and (iii) the
transferor and the transferee shall have agreed to reimburse the General Partner
for any incremental accounting fees and other expenses incurred by the General
Partner in making such allocation. If the transferor and transferee fail to give
notice to the Partnership in accordance with the proviso to the immediately
preceding sentence, all allocations shall be made in accordance with the
applicable requirements of Section 706 of the Code.

      SECTION 12.05. Securities Laws; Legends. (a) The limited partner interests
have been issued pursuant to a claim of exemption from the registration or
qualification provisions of U.S. federal and state and non-U.S. securities laws
and may not be sold or transferred without compliance with the registration or
qualification provisions of applicable U.S. federal and state and non-U.S.
securities laws or applicable exemptions therefrom.

      (b) Certificates for any limited partner interest or interests may be
issued evidencing a Limited Partner's limited partner interest. Each such
certificate shall bear such legends as may be required by applicable federal or
state laws, or as may be deemed necessary or appropriate by the General Partner
to reflect restrictions upon transfer contemplated herein.

      thereby.

      (b) The provisions of Section 3.03(d)(ii) may be waived with respect to
any Limited Partner affected by Section 3.03(d)(ii) in connection with any
Investment with the approval of the General Partner and such Limited Partner
affected by Section 3.03(d)(ii) as to such Investment.

      (c) Notwithstanding any other provision of this Agreement (except clauses
(i)-(iv) of Section 13.01(a)), the General Partner may, without the approval of

Partnership, the General Partner or any of its Affiliates and, if applicable,
any Parallel Investors, any of the following shall bind the Partnership, the

requiring the approval of Investors having a specified percentage of Invested
Capital or Capital Commitments, as the case may be, (i) for purposes of
calculating the arithmetic fraction represented by such percentage, there shall

invalid or unenforceable under the Delaware Act or other applicable law, such
invalidity or unenforceability shall not invalidate the entire Agreement, in
which case this Agreement shall be construed so as to limit any term or
provision so as to make it enforceable or valid within the requirements of
applicable law, and, in the event such term or provision cannot be so limited,
this Agreement shall be construed to omit such invalid or unenforceable

      such admission, each of the General Partners shall be removed as general
      partner; provided that upon such removal:

                  (i) the interest of each removed General Partner shall be
            converted into a special limited partner interest in the Partnership
            with a Capital Commitment equal to the amount of the Capital
            Contributions made by it prior to such date (and an Available
            Capital Commitment equal to $0.00) and each removed General Partner
            may not be removed as a Limited Partner without its written consent;

                  (ii) GCP, as a special Limited Partner following any removal
            (the "GCP Limited Partner"), shall retain its interest in its
            Investment Portion Percentage of all capital invested in, and
            profits related to, each Pre-2004

                                       3

            Investment and shall be entitled to receive its Investment Portion
            Percentage of all distributions of capital and profits in respect of
            such Pre-2004 Investments (including any temporary investment income
            related thereto) pursuant to the terms of this Agreement in effect
            immediately prior to the delivery of notice of removal hereunder as
            if it had remained the general partner of the Partnership, and the
            successor general partner shall not have any interest in (or
            otherwise any rights to receive distributions directly or indirectly
            in respect of) such Pre-2004 Investments;

                  (iii) The removed Managing General Partner, as a special
            Limited Partner following any removal (the "GCPMP Limited Partner"),
            shall retain its interest in its Investment Portion Percentage of
            all capital invested in, and profits related to, each Investment
            that was consummated by the Partnership after January 1, 2004 and
            prior to the effective date of its removal as General Partner under
            this Section 11.02 (the "GCPMP Investments") and shall be entitled
            to receive its Investment Portion Percentage of all distributions of
            capital and profits in respect of such GCPMP Investments (including
            any temporary investment income related thereto) pursuant to the
            terms of this Agreement in effect immediately prior to the delivery
            of notice of removal hereunder as if it had remained the general
            partner of the Partnership, and the successor general partner shall
            not have any interest in (or otherwise any rights to receive
            distributions directly or indirectly in respect of) such GCPMP
            Investments;

                  (iv) all allocations and distributions (including in
            connection with the Partnership's liquidating distributions), and
            any temporary investment income related thereto, with respect to any
            Investment otherwise allocable or payable to the successor General
            Partner, or to which the successor general partner is otherwise
            entitled, shall instead be made as a special allocation or
            distribution, as applicable, to the GCP Limited Partner and the
            GCPMP Limited Partner (the "Removed GP Limited Partners"), until the
            Removed GP Limited Partners have received cumulative allocations and
            distributions equal to the amount of allocations and distributions
            that the Removed GP Limited Partners otherwise would have been
            entitled to receive pursuant to the terms of this Agreement in
            effect immediately prior to the delivery of notice of removal
            hereunder calculated as if (x) the Removed GP Limited Partners had
            not been removed as General Partner pursuant to this Section 11.02
            and (y) no Investments had been made by the Partnership other than
            the Pre-2004 Investments and the GCPMP Investments;

                  (v) Greenhill and its Affiliates (including the Removed GP
            Limited Partners) shall no longer be bound by the covenants under
            Sections 2.06, 2.13 or 3.05 of this Agreement upon the effective
            date of removal; and

                                       4

                  (vi) the successor general partner shall assume and fund in
            cash any unpaid portion of the Capital Commitment of the Managing
            General Partner, as general partner.

      Any direct or indirect amendment on or after the effective date of the
      removal of the General Partners to the provisions of this Section 11.02 or
      any other provision of this Agreement that adversely affects the Removed
      GP Limited Partners' rights under this Section 11.02 (including, without
      limitation, any amendment to this Agreement that would adversely affect
      the Removed GP Limited Partners' allocations or distributions hereunder or
      require it to make any further capital contributions or payments on or
      after such removal) shall require the written consent of the Removed GP
      Limited Partners. A removal of the General Partners pursuant to this
      Section 11.02 shall be deemed a notice by the Partnership to terminate the
      Management Agreement pursuant to the terms thereof. The provisions of this
      Section 11.02 shall apply notwithstanding anything else to the contrary
      contained in this Agreement or the Investment Advisory Agreement."

      8. Ratification and Confirmation of Partnership Agreement. Except as so
modified pursuant to this Amendment, the Partnership Agreement is hereby
ratified and confirmed in all respects.

      9. Governing Law. This Amendment shall be governed by the laws of the
State of Delaware.
