                      ------------------------------------------
opposite the name of each Limited Partner listed on Exhibit A attached hereto is
such Limited Partner's capital commitment to the Partnership. (The capital
commitment of each Partner (as it may be subsequently adjusted pursuant to the
terms hereof) is referred to herein as the Partner's "Capital Commitment" and
                                                      ------------------
the total Capital Commitments of the Partners shall be referred to herein as the
"Total Committed Capital.") Each Limited Partner's Capital Commitment represents
 -----------------------
the aggregate amount of capital that such Limited Partner has agreed to
contribute to the Partnership in accordance with the terms hereof. No Limited
Partner shall be obligated to contribute capital to the Partnership an amount in
excess of its Capital Commitment. E*Trade's Capital Commit-

ment set forth in Exhibit A reflects the agreed fair market value of the
Securities being contributed by E*Trade to the Partnership and shall be the sole
Capital Commitment of E*Trade.

               3.2.   Capital Contributions by the Limited Partners
                      ---------------------------------------------

                      (a)  As its sole Capital Contribution, E*Trade has
contributed the Securities listed in Exhibit B, which Securities had the agreed
values when contributed set forth thereon. The Limited Partners (other than
E*Trade) shall make their Capital Contributions to the Partnership, payable by
wire transfer or check, in installments (each such payment being referred to as
a "Drawdown"). Such Capital Contributions shall be made upon no less than
   --------
fourteen (14) days' prior written notice from the General Partner (a "Drawdown
                                                                      --------
Notice"), in such amounts as may be determined in the sole discretion of the
------
General Partner and at such time, subject to the fourteen (14) day notice
period, as the General Partner shall specify in the Drawdown Notice (the
"Drawdown Date"). All Drawdowns shall be in U.S. dollars. No Limited Partner
 -------------
shall have the right to make partial payments of a required Capital
Contribution. Each Drawdown Notice shall be given to each Limited Partner of the
Partnership. The additional capital required of the respective Limited Partners
upon any Drawdown shall be based on the relative amounts of the unpaid balances
of their respective Capital Commitments.

                      (b)  After the expiration of the Investment Period, the
General Partner shall not be authorized to call (and the Partners shall not be
obligated to make) any Capital Contributions to fund investments which the
Partnership is not contractually obligated to make at such time other than for:

                           (1)   Investments reasonably expected to close within
         ninety (90) days after the expiration of the Investment Period;

                           (2)   Investments as to which, prior to the
         expiration of the Investment Period, the Partnership and the
         prospective company or entity in which such investment is to be made
         have a letter of intent or a definitive agreement setting forth the
         material terms and conditions of such investment;

                           (3)   Investments in partnerships, limited liability
         companies and other pass-through entities pursuant to capital
         commitments made during the Investment Period; or

                           (4)   Follow-On Investments (including Follow-On
         Investments with respect to investments in which the initial investment
         by the Partnership is made pursuant to clause (1), (2) or (3) of this
         Paragraph 3.2(b)).

               3.3.   Capital Commitment of the General Partner.  The General
                      -----------------------------------------
Partner's Capital Commitment shall be an aggregate amount of $350,000.

               3.4.   Capital Contributions of the General Partner. On any date
                      --------------------------------------------
on which a Limited Partner makes a contribution to the capital of the
Partnership, the General Partner shall contribute to the Partnership in such
amount as may be necessary to cause the percentage of the General Partner's
Capital Commitment actually contributed to the Partnership to be the same as the
percentage of the Capital Commitments of the Limited Partners (other than
E*Trade) actually

                                      11.
<PAGE>

contributed to the Partnership as of such date. Such contribution may be made,
at the General Partner's discretion, in the form of a promissory note.

               3.5.   Defaulting Partners
                      -------------------

                      (a)  If a Partner fails to pay any amount which it is
required to pay to the Partnership on or before the date when such amount is due
and payable, such Partner shall be deemed to be in default hereunder (a
"Defaulting Partner"), and written notice of default shall be given to such
 ------------------
Limited Partner by the General Partner by certified or registered mail. The
Partnership shall be entitled to enforce the obligations of each Partner to make
the contributions to capital required in this Agreement and shall have all
remedies available at law or in equity in the event any such contribution is not
so made. In the event of any legal proceedings relating to a default by a
Defaulting Partner, such Defaulting Partner shall pay all costs and expenses
incurred by the Partnership, including attorneys' fees, if the Partnership shall
prevail. Further, such Defaulting Partner shall be obligated to pay the
Partnership interest with respect to the amount of any Capital Contribution not
made when required by this Article, with such interest commencing on the
Drawdown Date for such contribution and ending on the date such contribution is
made to the Partnership. Such interest shall be calculated on the basis of the
then current reference rate announced by Wells Fargo Bank, N.A., or by any other
U.S. commercial bank with capital in excess of Five Hundred Million Dollars
($500,000,000) selected by the General Partner, plus five percent (5%) per
annum, but not in excess of the amount allowable by law.

                      (b)  In addition to the remedies provided under Paragraph
3.5(a), if the Defaulting Partner does not cure a default in the payment of a
required contribution within ten (10) business days of the receipt of the notice
specified in Paragraph 3.5(a), the General Partner (in its sole discretion) may,
as liquidated and agreed current damages to the non-defaulting Partners for such
default (it being agreed that it would be difficult to fix the actual damages to
such Partners), cause and treat the Defaulting Partner's Capital Account to be
reduced by an amount equal to fifty percent (50%), which amount shall thereupon
become unrestricted assets of the Partnership and shall be allocated pro rata to
and among the respective Capital Accounts of the non-defaulting Partners in such
proportion as the Capital Account of each such non-defaulting Partner then bears
to the sum of the Capital Accounts of all non-defaulting Partners. The
Defaulting Partner's remaining fifty percent (50%) interest in its Capital
Account shall automatically be converted into a general unsecured obligation of
the Partnership, which obligation shall not bear any interest and shall be due
six (6) months after the Termination Date of the Partnership. Upon the
expiration of the ten (10) day period after the mailing of the notice of default
and the election by the General Partner to exercise its remedy under this
subparagraph (b), a Defaulting Partner shall automatically cease to be a Partner
under this Agreement and shall have no further interest, right or claim in or
against the Partnership, including any right or obligation to make subsequent
Capital Contributions when called.

                      (c)  Notwithstanding the foregoing, if, at any time before
a Capital Contribution required by Paragraph 3.2 becomes due, a Partner obtains
and delivers to the Partnership an opinion of counsel (which opinion shall be
reasonably acceptable to the General Partner) to the effect that the payment by
such Partner of any portion of any remaining Capital Contributions required by
this Agreement will be unlawful or that there is a material likelihood that such
payment will be unlawful, then (A) such Partner shall have no further right or
obliga-

                                      12.
<PAGE>

tion to pay the pertinent portion of such Capital Contribution (depending on
whether the Partner is withdrawing from or simply reducing its interest in the
Partnership), (B) such Partner's Capital Commitment specified on Exhibit A shall
be reduced by an amount equal to such Capital Contribution, and (C) such Partner
shall not, by reason of his or her failure to make such Capital Contribution, be
deemed or treated as a Defaulting Partner for purposes of this Paragraph 3.5.

                      (d)  The General Partner may seek to fund the amount of
any Capital Contribution that a Defaulting Partner has failed to contribute or
that is not contributed pursuant to Paragraph 3.5(c) (the "Shortfall Amount") as
                                                           ----------------
follows:

                           (1)   The General Partner may in its discretion
         determine to increase the amount of the Capital Contributions required
         from each Partner to fund such Shortfall Amount ratably in accordance
         with the Partners' relative unpaid Capital Commitments (not to exceed
         any Partner's remaining Capital Commitment).

                           (2)   Alternatively, the General Partner may offer
         the Partners who have made Capital Contributions the opportunity to
         make additional Capital Contributions to fund such Shortfall Amount. If
         any such Partner declines to invest in all or any portion of its share
         of the Shortfall Amount, such uncommitted amount will be offered to any
         other Partner who has invested its share of the Shortfall Amount and
         concurrently advised the General Partner of its willingness to make a
         Capital Contribution in excess of such share, and the General Partner
         shall allocate such uncommitted amount among all such other Partner on
         a basis the General Partner determines in its discretion is, under the
         circumstances, equitable and practicable.

                           (3)   To the extent any Shortfall Amount has not been
         fully funded by the Partners, the General Partner may seek to fund the
         remaining Shortfall Amount by offering Limited Partner interests to any
         other person on substantially the same economic terms and conditions as
         are provided to the Partners.

                       CAPITAL ACCOUNTS AND ALLOCATIONS

               4.1.   Capital Accounts.  A Capital Account shall be maintained
                      ----------------
on the Partnership's books for each Partner. In the event any interest in the
Partnership is transferred in accordance with the terms of this Agreement, the
transferee shall succeed to the Capital Account of the transferor to the extent
it relates to the transferred interest.

               4.2.   Adjustments to Capital Accounts
                      -------------------------------

                      (a)  The Capital Account of each Partner shall be
increased by:
---------

                           (1)   the amount of money and the fair market value
         of any property other than money contributed to the Partnership by such
         Partner (in the case of a contribution of property, net of any
         liabilities secured by such property that the Partnership is considered
         to assume or hold subject to for purposes of Section 752 of the Code),

                                      13.
<PAGE>

                           (2)   such Partner's share of Capital Transaction
         Gain and Net Income (or items thereof) allocated to its Capital Account
         pursuant to this Agreement, and

                           (3)   any other amounts required by Treasury
         Regulation Section 1.704-1(b), provided the General Partner determines
         that such increase is consistent with the economic arrangement among
         the Partners as expressed in this Agreement.

                      (b)  The Capital Account of each Partner shall be
decreased by:
---------

                           (1)   the amount of money and the fair market value
         of any property other than money distributed by the Partnership
         (determined pursuant to Paragraph 9.2 hereof as of the date of
         distribution) to such Partner pursuant to the provisions of this
         Agreement (net of any liabilities secured by such property that such
         Partner is considered to assume or hold subject to for purposes of
         Section 752 of the Code),

                           (2)   such Partner's share of Capital Transaction
         Loss and Net Loss (or items thereof) allocated to its Capital Account
         pursuant to this Agreement, and

                           (3)   any other amounts required by Treasury
         Regulation Section 1.704-1(b), provided the General Partner determines
         that such decrease is consistent with the economic arrangement among
         the Partners as expressed in this Agreement.

               4.3.   Allocation of Capital Transaction Gain or Loss
                      ----------------------------------------------

                      (a)  Allocation of Capital Transaction Gain. Capital
                           --------------------------------------
Transaction Gain of the Partnership for each Fiscal Year or Interim Period shall
be allocated as follows:

                           (1)   Twenty percent (20%) of the Partnership's
         Capital Transaction Gain shall be allocated to the General Partner.

                           (2)   The remaining eighty percent (80%) of the
         Partnership's Capital Transaction Gain shall be allocated to all
         Partners as a group.

                           (3)   Notwithstanding the foregoing, if one or more
         Limited Partners have been allocated a Reallocated Loss pursuant to
         Paragraph 4.5, then Partnership Capital Transaction Gain that would
         otherwise be allocated entirely to the General Partner pursuant to
         Paragraph 4.3(a)(1) shall instead be allocated first to the Limited
         Partners (in proportion to the amount of Reallocated Loss previously
         allocated to them) until the Limited Partners have been allocated an
         aggregate amount of Capital Transaction Gain equal to the previously
         allocated Reallocated Loss that has not been restored by prior
         allocations pursuant to this subparagraph and then any such remaining
         Capital Transaction Gain shall be allocated to the General Partner.

                      (b)  Allocation of Capital Transaction Loss. Capital
                           --------------------------------------
Transaction Loss of the Partnership for each Fiscal Year or Interim Period shall
be allocated as follows:

                                      14.
<PAGE>

                           (1)   Twenty percent (20%) of the Partnership's
         Capital Transaction Loss shall be allocated to the General Partner.

                           (2)   The remaining eighty percent (80%) of such
         Capital Transaction Loss shall be allocated to all Partners as a group.

               4.4.   Allocation of Net Income or Loss. Net Income or Loss of
                      --------------------------------
the Partnership for each Fiscal Year or Interim Period shall be allocated to all
Partners as a group.

               4.5.   Reallocation of Losses. If for any Fiscal Year or Interim
                      ----------------------
Period after the Partnership's Capital Transaction Gain or Loss and Net Income
or Loss has been allocated pursuant to Paragraphs 4.3 and 4.4 the closing
Adjusted Capital Balance of the General Partner has been reduced to less than
zero by more than the amount necessary to properly reflect the General Partner's
obligation to recontribute amounts to the Partnership pursuant to Paragraph 8.2
upon termination of the Partnership, then an amount of Capital Transaction Loss
and, to the extent necessary, Net Loss (the "Reallocated Loss") for such Fiscal
                                             ----------------
Year or Interim Period shall be reallocated from the General Partner to the
Limited Partners as a group so that the General Partner's closing Adjusted
Capital Balance is not reduced below zero by more than the amount necessary to
properly reflect the General Partner's obligation to recontribute amounts to the
Partnership pursuant to Paragraph 8.2 upon termination of the Partnership. A
Reallocated Loss may be restored only from future Capital Transaction Gain.

               4.6.   Allocation Among Partners as a Group. Except as otherwise
                      ------------------------------------
specifically provided in this Agreement, all Capital Transaction Gain or Loss
and Net Income and Loss (and items thereof) allocated to the Partners (or a
group of Partners) as a group for any period shall be allocated among such
Partners in proportion to their respective Partnership Percentages as of the end
of such period. In making such allocations, any changes in Partnership
Percentages as a result of changes in the Capital Commitments of the Partners,
any exclusion of any Partners from particular investments, any contributions of
Partners to fund any Shortfall Amount and similar matters shall be taken into
account.

               4.7.   Special Allocation Among Late-Entering Limited Partners of
                      ----------------------------------------------------------
Organization and Operating Expenses. The following items of Net Income or Loss
-----------------------------------
are collectively referred to herein as "Operating Expenses":

                      (a)  The Management Fee and other payments and
reimbursements of expenses paid pursuant to Article V other than amounts
capitalized as part of the cost of Securities or other assets for federal income
tax purposes; and

                      (b)  All expenditures of the Partnership classified for
federal income tax purposes as organization or syndication expenses.

               Notwithstanding Paragraph 4.6, if additional Limited Partners are
admitted to the Partnership pursuant to Paragraph 7.6(b) hereof during a
particular period, the Operating Expenses for such period allocable to the
Limited Partners shall be allocated among the Original Partners and the Limited
Partners admitted pursuant to Paragraph 7.6(b) hereof so that, to the extent
possible, the cumulative amount of Operating Expenses allocated to each Limited
Partner is proportionate to such Limited Partner's Partnership Percentage as
compared to the Partnership

                                      15.
<PAGE>

Percentages of the Limited Partners as a group (taking into account the
additional Limited Partners admitted pursuant to Paragraph 7.6(b)).

               4.8.   Allocations and Distributions Attributable to Removed
General Partner. Notwithstanding the foregoing sections of this Article IV, if
the initial General Partner ceases to be the General Partner and a successor
General Partner is appointed pursuant to Paragraph 2.2, such initial General
Partner shall continue to receive the allocations and distributions otherwise
attributable to the General Partner pursuant to this Article IV, Article VI and
Article VIII both in its capacity as a General Partner and in its capacity as a
Limited Partner; provided, however, that on or after the date a successor
General Partner is appointed pursuant to Paragraph 2.2, such allocations and
distributions attributable to the initial General Partner in its capacity as a
General Partner shall be calculated only with respect to investments that were
made or as to which the Partnership was committed to invest or had reserved
capital to invest at such time. Notwithstanding the foregoing if the General
Partner is removed as a result of committing an act of fraud or willful
misconduct against the interest of the Limited Partners, the General Partner's
rights to further allocations pursuant to Paragraphs 4.3(a)(1) and 4.3(b)(1)
shall cease upon such removal. The General Partner shall nevertheless continue
to be subject to any obligations to the Partnership pursuant to Paragraph 8.2.

                                   ARTICLE V

                           MANAGEMENT FEE; EXPENSES

               5.1.   Entitlement to Management Fee. As compensation for its
                      -----------------------------
services rendered in managing the Partnership, the General Partner shall be
entitled to recover a fee calculated as prescribed in this Article V (the
"Management Fee"). The Management Fee shall not be considered a distribution of
profits or a return of capital for the purpose of any provision of this
Agreement, but shall be considered an expense of the Partnership, and shall be
deducted from Partnership Net Income or added to Partnership Net Loss in
determining the Net Income or Net Loss of the Partnership pursuant to Article IV
hereof.

               5.2.   Payment of Management Fee. The Management Fee shall be at
                      -------------------------
an annual rate of 1.75% of the Total Committed Capital of the Partnership
through the end of the Investment Period. After the end of the Investment
Period, the Management Fee shall be at an annual rate of 1.75% of the total cost
of the Portfolio Securities held by the Partnership, with the cost of the
Portfolio Securities being redetermined for this purpose on January 1 and July 1
of each Fiscal Year after the end of the Investment Period. The Management Fee
shall commence to accrue on the date of this Agreement. Payment of the
Management Fee shall be made (i) with respect to the first Fiscal Quarter of the
Partnership (ending September 30, 1999), at any time on or prior to September
30, 1999, in an amount equal to the percentage of the annual Management Fee as
reflects the number of days from the date of this Agreement through September
30, 1999, divided by 365 days, and (ii) thereafter quarterly in advance on the
first day of each Fiscal Quarter of the Partnership in an amount equal to 25% of
the annualized Management Fee. Additional Management Fees resulting from an
increase in the Total Committed Capital shall be payable promptly after the
acceptance of additional Capital Commitments (with such payment being prorated
to reflect the remaining term of the then current fiscal period). The Management
Fee shall be reduced by the amount of any transaction fees (but not including
director options or

                                      16.
<PAGE>

director fees) received by the General Partner or its members or Affiliates (net
of associated expenses) from Portfolio Companies. Such reduction shall be made
in each installment of the Management Fee until the entire net amount of the
transaction fees have offset the Management Fees.

               5.3.   Payment of Expenses.
                      -------------------

                      (a)  Except as set forth in Paragraph 5.3(b) hereof, the
General Partner agrees to incur on behalf of the Partnership and to otherwise
assume all expenses attributable to the management and administration of the
investment activities of the Partnership. Such expenses include (but are not
limited to) consulting fees, compensation and expenses of the employees of the
General Partner, including any salaries of members of the General Partner in
their capacity as employees of the General Partner, expenses for administrative,
bookkeeping, clerical and related support services, insurance, office space and
facilities, utilities, telephone and travel insofar as they relate to the
investment activities of the Partnership.

                      (b)  The Partnership shall pay, or reimburse the General
Partner (or E*Trade if and to the extent it incurs expenses on behalf of the
Partnership) for all expenses of the Partnership (or incurred by the General
Partner or E*Trade for or on behalf of the Partnership) which (i) relate to the
management and administration of the Partnership itself as a going concern (as
opposed to operating expenses incurred in connection with the Partnership's
investment activities), or (ii) are incurred in the purchase, holding, sale,
exchange or other disposition of investments. Such expenses include (without
limitation) organizational and offering expenses of the Partnership up to an
aggregate of two hundred thousand dollars ($200,000); any taxes which may be
assessed against the Partnership; commissions or brokerage fees or similar
charges incurred in connection with the purchase and sale of securities
(including any merger or transaction fees payable to third parties); interest
expense and financing charges for borrowed money; all expenses relating to
litigation and threatened litigation involving the Partnership; normal
investment banking, legal, custodial, registration, auditing and accounting
services provided to the Partnership; and any other expenses associated with the
acquisition, holding or disposition of investments. The Partnership also shall
pay or reimburse the General Partner (or E*Trade) for all payments to third
parties related to the investment activities of the Partnership in developing,
negotiating and structuring prospective or potential investments with respect to
which the Partnership enters into a purchase agreement, letter of intent or
memorandum of understanding, but that are not ultimately made.

               5.4.   No Salaries to General Partner. The General Partner and
                      ------------------------------
its members shall receive no salaries from the Partnership. This paragraph shall
not restrict the payment of salaries by the General Partner.

               WITHDRAWALS BY AND DISTRIBUTIONS TO THE PARTNERS

               6.1.   Interest. No interest shall be paid to any Partner on
                      --------
account of its interest in the capital of, or on account of its investment in,
the Partnership.

               6.2.   Withdrawals by the Partners. No Partner may withdraw any
                      ---------------------------
amount from its Capital Account except as specifically provided in this
Agreement.

               6.3.   Mandatory Cash Distributions. Within ninety (90) days
                      ----------------------------
after the end of each Fiscal Year, the Partnership shall distribute to each
Partner cash in an amount equal to the aggregate federal and state income tax
liability such Partner would have incurred as a result of such Partner's
ownership of an interest in the Partnership, calculated: (i) as if allocations
from the Partnership of any Net Capital Gain and any Net Loss were, for such
Fiscal Year, the sole source of taxable income and loss for such Partner; (ii)
as if such Partner were an individual taxable at the combined maximum marginal
rate provided with respect to such Net Capital Gain and Net Loss (taking into
account the character of the items of Net Capital Gain and Net Loss for tax
purposes) under applicable federal and state income tax laws applicable to
individuals residing in California; and (iii) taking into account the
deductibility of state taxes in the calculation of federal income taxes (a "Tax
                                                                            ---
Distribution"). Any Tax Distributions to a Partner shall reduce the amounts
------------
otherwise distributable to the Partner pursuant to Paragraph 6.4.

               6.4.   Additional Distributions. The General Partner (i) shall
                      ------------------------
distribute any proceeds from the Sale or Exchange of Securities of Portfolio
Companies as soon as practicable following such Sale or Exchange, subject to the
retention of such amounts as are necessary to pay Partnership expenses and
obligations (including the Management Fee) and/or for permitted reinvestments
and (ii) may in its discretion make distributions of Securities of Portfolio
Companies. All distributions under this Paragraph 6.4 shall be made as follows:

                      (a)  At any time prior to achievement of Payout if the
Fair Value Test is not satisfied, all such distributions will be made to the
Partners as a group in proportion to their respective Partnership Percentages.

                      (b)  At any time prior to achievement of Payout if the
Fair Value Test is satisfied, all such distributions will be made, in the
General Partner's sole discretion, either (1) to the Partners as a group in
proportion to their respective Partnership Percentages, or (2)(i) first, to the
General Partner until the General Partner has received distributions pursuant to
this Paragraph 6.4(b)(2)(i) and Tax Distributions pursuant to Paragraph 6.3
equal to a maximum of twenty percent (20%) of the total amount distributed and
being distributed to all Partners pursuant to Paragraphs 6.3 and 6.4(a) and this
Paragraph 6.4(b), and (ii) the remainder of such distributions will be made to
the Partners as a group in proportion to their respective Partnership
Percentages; provided, however, that the amount distributable to the General
             -----------------
Partner pursuant to Paragraph 6.4(b)(2)(i) will in no event exceed either (x)
the cumulative amount of the Capital Transaction Gain net of Capital Transaction
Loss allocated to the General Partner under Paragraphs 4.3(a)(1) and 4.3(b)(1)
or (y) an amount which would cause the General Partner's Fair Value Capital
Account to be reduced below the amount of the General Partner's Capital
Contributions or would further reduce an existing balance of such Fair Value
Capital Account that is already less than the General Partner's Capital
Contributions; provided, further that the General Partner will not cause or
               -----------------
permit the Partnership to make any distribution to the General Partner pursuant
to Paragraph 6.4(b)(2)(i) unless the Partnership has made (and/or provided
through reserves for) distributions to each Partner, with respect to the Fiscal
Year in which any proposed distribution under Paragraph 6.4(b)(2)(i) otherwise
would occur, in aggregate amounts equal to

                                      18.
<PAGE>

the Tax Distribution to which each Partner would be entitled pursuant to
Paragraph 6.3 with respect to such Fiscal Year if such Fiscal Year ended on the
date of the proposed distribution.

                      (c)  After Payout has been achieved, all such
distributions will be made to the Partners in proportion to the positive
balances in their respective Capital Accounts after such Capital Accounts have
been adjusted to reflect all Capital Transaction Gain or Loss (including Capital
Transaction Gain or Loss arising in connection with the distribution and Sale or
Exchange of Securities) through the date of the distribution.

                      (d)  Each class of Securities to be distributed in kind
shall be distributed to the Partners in proportion to their respective shares of
the proposed distribution, except to the extent that a disproportionate
distribution of Securities is necessary in order to avoid distributing
fractional shares. For purposes of the preceding sentence, each lot of stock or
other Securities having a separately identifiable tax basis or holding period
will be treated as a separate class of Securities. Notwithstanding anything
contained in this Agreement: (i) no distribution (other than a Tax Distribution)
will be made to any Partner if, and to the extent that, such distribution would
(x) cause such Partner's Capital Account to be negative by an amount which
exceeds such Partner's Zero Balance Amount or (y) further reduce a balance in
such Partner's Capital Account that is already negative by an amount which
exceeds such Partner's Zero Balance Amount; and (ii) no distribution will be
made unless all liabilities of the Partnership to persons other than Partners
have been satisfied or, in the good faith judgment of the General Partner, there
remains property of the Partnership sufficient to satisfy such liabilities.

                      (e)  Except upon liquidation of the Partnership or with
the approval of the General Partner and a Majority in Interest of the Limited
Partners, no distribution shall be made other than in cash or Marketable
Securities.

                      (f)  Immediately prior to any distribution in kind of
Securities (or other Partnership assets) pursuant to any provision of this
Agreement (including pursuant to Article VIII), the difference between the fair
market value and the Book Value of any Securities (or other Partnership assets)
distributed shall be allocated to the Partners as Capital Transaction Gain or
Loss pursuant to Article IV.

                      (g)  Securities distributed in kind pursuant to this
Paragraph 6.4 shall be subject to such conditions and restrictions as the
General Partner determines are legally required.

                      (h)  For purposes of this Agreement, all distributions of
Securities shall be deemed to have been made on the date on which the
Partnership commences the distribution of the Securities to the Limited
Partners, provided that the delivery of the Securities is promptly completed.

                                  ARTICLE VII

                      MANAGEMENT, DUTIES AND RESTRICTIONS

               7.1.   Management by General Partner. The General Partner shall

have the sole and exclusive right and power to manage, control, and conduct the
affairs of the Partnership and

                                      19.
<PAGE>

to perform any and all acts on behalf of the Partnership that the General
Partner deems necessary, advisable or incidental to carry out any or all of the
objects and purposes of the Partnership.

               7.2.   Indebtedness; Restrictions; Reinvestments
                      -----------------------------------------

                      (a)  The Partnership may borrow money and guarantee the
obligations of, and supply letters of credit on behalf of, Portfolio Companies;
provided that at no time shall the Partnership guarantee, directly or
indirectly, obligations of a General Partner or a Limited Partner; and further
provided that the Partnership shall provide a guaranty to a Portfolio Company
only if each member of the General Partner with an interest in that Portfolio
Company provides a guaranty on the same terms and in amount proportional to the
investment of such member as compared to the Partnership. While outstanding, any
guarantee of the obligations of any Portfolio Company shall be considered an
investment in such Portfolio Company for purposes of Paragraph 7.2(b).
Additionally, except with the approval of a Majority in Interest of the Limited
Partners, the Partnership shall not at any point in time be the guarantor (or
the obligor on any letter of credit) of then-current liabilities that, in the
aggregate, amount to more than thirty percent (30%) of the Total Committed
Capital of the Partnership.

                      (b)  Except with the approval of a Majority in Interest of
the Limited Partners and except with respect to the Securities contributed by
E*Trade as described in Exhibit B, the Partnership shall not invest more than
twenty-five percent (25%) of the aggregate amount of the Total Committed Capital
(i) in the Securities of any one issuer or its affiliates, (ii) in any other
investment pool or partnership, or (iii) in Securities purchased by the
Partnership in the over-the-counter market or that are listed on a securities
exchange (with the twenty-five percent (25%) test being applied separately with
respect to each of the foregoing three categories of investments). The
limitations set forth in this Paragraph 7.2(b) shall not apply to any funds of
the Partnership which are invested in investments described in Paragraph 7.2(e).

                      (c)  The Partnership shall not reinvest any proceeds
realized on the Sale or Exchange of Securities of Portfolio Companies in
Securities of other Portfolio Companies except for Follow-On Investments. In no
event shall the Partnership make cumulative investments in Securities of
Portfolio Companies in excess of the Total Committed Capital.

                      (d)  No Partner shall be permitted to borrow money from
the Partnership.

                      (e)  Pending use of funds to make investments in
Securities of Portfolio Companies, to make distributions or to pay expenses or
obligations of the Partnership in accordance with the terms hereof, the funds of
the Partnership shall be invested by the General Partner only in (i) securities
issued by, or backed by the full faith and credit of, the United States
government, (ii) certificates of deposit issued by commercial banks with capital
in excess of Five Hundred Million Dollars ($500,000,000), (iii) commercial paper
rated A-1 or P-1, or (iv) shares in investment companies generally known as
"money market funds" which have assets in excess of Two Hundred Fifty Million
 ------------------
Dollars ($250,000,000).

                      (f)  The Partnership shall not invest in (i) any
Securities the purchase of which is opposed by the issuer's board of directors;
or (ii) options contracts or futures con-

tracts, or any other security, the value of which is based upon, or derived
from, any underlying index, reference rate, other security, commodity or other
asset; provided, however, that this restriction shall not be deemed to prohibit
the General Partner from (A) hedging Portfolio Company investments so long as
such transactions are reasonably related to the amount and type of Securities
being hedged and are not undertaken for independent investment purposes, (B)
hedging the currency risk of foreign Portfolio Company investments, (C)
investing in any Security the value of which is based upon, or derived from, any
Security already held by the Partnership, and (D) investing in traditional
options, warrants and other rights to acquire Securities that would otherwise be
permitted Portfolio Company investments under the terms of this Agreement.

                      (g)  The Partnership shall not invest in real estate, oil
or gas investments, commodities or in securities bearing unlimited liability.

                      (h)  The Partnership shall not engage in uncovered short
sales.

                      (i)  The Partnership shall not make any investment in an
issuer which is organized in any jurisdiction outside the United States and
Canada (each such issuer being a "Foreign Entity"), unless the Partnership has
                                  --------------
received, prior to or at the closing of any such investment, a Limited Liability
Entity Opinion with respect to the issuer's form of entity. A "Limited Liability
                                                               -----------------
Entity Opinion" shall be an opinion of counsel, licensed or otherwise authorized
--------------
to practice in the jurisdiction in which a particular Foreign Entity is
organized, which opinion may be relied upon by the Partnership and does not
contain more than reasonable carve-outs by opining counsel, stating (i) that the
Partnership shall not be obligated beyond its committed investment in such
Foreign Entity for any debt, obligation or liability of an entity of the form of
the particular issuer, solely by reason of the Partnership being an investor in
such an entity; and (ii) that no Limited Partner of the Partnership shall be
obligated for any debt, obligation or liability of an entity of the form of the
particular issuer, solely by reason of the Partnership being an investor in such
an entity. Once the Partnership has received such an opinion for investments in
a particular form of entity in a particular jurisdiction, such opinion shall
satisfy the requirements of this paragraph for all investments in other Foreign
Entities of the same form as that which is the subject of the opinion. The
Partnership shall not invest an aggregate of more than thirty percent (30%) of
the Total Committed Capital in Securities of Foreign Entities.

                      (j)  The Partnership shall not make any investment in any
other investment pool or partnership if a management fee and/or "carried
interest" is payable with respect to such investment unless the General Partner
waives its Management Fee and/or "carry" with respect to such investment.

               7.3.   Investment Representation of the Limited Partners. This
                      -------------------------------------------------
Agreement is made with each Limited Partner in reliance upon such Limited
Partner's representation to the Partnership, which by executing this Agreement
the Limited Partner hereby confirms, that such Partner's interest in the
Partnership is being acquired for investment, and not with a view to the sale or
distribution of any part thereof, and that such Partner has no present intention
of selling, granting participation in, or otherwise distributing the same. Each
Limited Partner further represents that such Limited Partner does not have any
contract, undertaking, agreement, or arrange-

                                      21.
<PAGE>

ment with any person to sell or transfer to any third person such Limited
Partner's interest in the Partnership.

               7.4.   Accredited Investor Representation. Each Limited Partner
                      ----------------------------------
represents that such Partner has such knowledge and experience in financial and
business matters as to be capable of evaluating the merits and risks of an
investment in the Partnership and that such Partner is an accredited investor,
as that term is defined in Regulation D promulgated by the Securities and
Exchange Commission.

               7.5.   No Control by the Limited Partners; Rights of the Limited
                      ---------------------------------------------------------
Partners.
--------

                      (a)  The Limited Partners shall take no part in the
control or management of the affairs of the Partnership nor shall a Limited
Partner have any authority to act for or on behalf of the Partnership except as
is specifically permitted by this Agreement and as is specifically required by
the Delaware Act.

                      (b)  In addition to any other restrictions applicable to
Limited Partners set forth in this Agreement and notwithstanding any other
provisions thereof, for so long as the Partnership has an investment in a Media
Company, any Limited Partner that elects in writing to be insulated from the
"multiple ownership attribution" rules and policies of the FCC (an "Insulated
Limited Partner") shall not (and if such Limited Partner is not an individual,
each officer, director, partner or equivalent non-corporate official of such
Limited Partner acting on behalf of or as a representative of such Limited
Partner in its capacity as a Limited Partner of the Partnership shall not):

                           (1)   act as an employee of the Partnership if his or
         her functions, directly or indirectly, relate to the media business of
         the Partnership or any Media Company in which the Partnership has an
         investment;

                           (2)   serve, in any material capacity, as an
         independent contractor or agent with respect to the media business of
         the Partnership or any Media Company in which the Partnership has an
         investment;

                           (3)   communicate on matters pertaining to the
         day-to-day media operations of the Partnership or a Media Company with
         (i) an officer, director, partner, agent, representative or employee of
         such Media Company, or (ii) the General Partner;

                           (4)   perform any services for the Partnership
         materially relating to the media activities of the Partnership or any
         Media Company in which the Partnership has an investment, except that
         any Limited Partner may make loans to, or act as a surety for, the
         Partnership or any such Media Company;

                           (5)   vote on the admission of any new General
         Partner to the Partnership unless such admission is approved by the
         General Partner;

                           (6)   become actively involved in the management or
         operation of the Partnership's media businesses; or

                                      22.
<PAGE>

                           (7)   vote for the removal of the General Partner
         except where the General Partner is subject to Bankruptcy proceedings,
         is adjudicated incompetent by a court of competent jurisdiction, or is
         removed for any cause which is determined by an independent party to
         constitute criminal conduct other such extraordinary conduct with
         respect to which a prudent investor would require the right to remove
         the General Partner.

               7.6.   Admission of Additional Partners.
                      --------------------------------

                      (a)  Subject to Paragraph 7.7 and subparagraph (b) below,
no additional person may be admitted to the Partnership, either as a limited or
general partner, without the prior written consent of both the General Partner
and Two-Thirds in Interest of the Limited Partners.

                      (b)  For a period ending on October 31, 1999 (the "Final
                                                                         -----
Closing Date"), the General Partner may admit persons as additional Limited
------------
Partners without the consent of any of the then Limited Partners, provided that
the Total Committed Capital of the Partnership shall not exceed one hundred
million dollars ($100,000,000). Following the admission of any such subsequently
admitted Limited Partners pursuant to this Paragraph 7.6(b), such Limited
Partners shall be deemed for all purposes of this Agreement (unless expressly
provided to the contrary herein) to have been admitted as of the original date
of this Agreement. Any Limited Partner admitted pursuant to this Paragraph
7.6(b) shall, upon admission, contribute to the Partnership the same portion of
such Limited Partner's Capital Commitment as the previously admitted Limited
Partners have contributed with respect to their Capital Commitments. Upon the
admission of any additional Limited Partners to the Partnership pursuant to this
Paragraph 7.6(b), the assets of the Partnership shall not be revalued except in
the discretion of the General Partner.

                      (c)  In addition to the Capital Contribution required
under Paragraph 7.6(b), each Limited Partner admitted as an additional Limited
Partner pursuant to Paragraph 7.6(b) shall be required to pay to the Partnership
interest at the Wells Fargo Bank, N.A. "prime rate" (in effect at the time the
additional Limited Partner interest was acquired) based on the amount of the
Capital Contribution payable under Paragraph 7.6(b) and the time period(s) from
the existing Limited Partners' prior Capital Contributions to the Partnership to
the date that the Capital Contribution under Paragraph 7.6(b) is made. Such
interest shall accompany the Capital Contribution payable under Paragraph 7.6(b)
and shall be immediately distributed pro rata to and among all existing Partners
(based on their respective Partnership Percentages immediately prior to the
issuance of such additional Limited Partner interests). The payment of such
interest to the Partnership shall not be considered a Capital Contribution and
shall not be considered an item of Capital Transaction Gain or Loss or Net
Income or Loss allocable pursuant to Article IV; furthermore, the distribution
to the existing Partners shall not result in a reduction in their Capital
Accounts.

                                      23.

               7.7.   Assignment or Transfer of Partnership Interests
                      -----------------------------------------------

                      (a)  The General Partner shall not sell, assign, pledge,
mortgage or otherwise dispose of or transfer its interest in the Partnership
without the prior written consent of Two-Thirds in Interest of the Limited
Partners.

                      (b)  No Limited Partner shall sell, assign, pledge,
mortgage, or otherwise dispose of or transfer its interest in the Partnership
without the prior written consent of the General Partner. Notwithstanding the
foregoing, a Limited Partner may sell, assign, pledge, mortgage, or otherwise
dispose of or transfer its interest in the Partnership without such consent (i)
to any affiliate of the Limited Partner; or (ii) as may be required by any law
or regulation; provided, however, that in the case of any permitted transfer,
the General Partner receives at least ten (10) days' prior written notice of
such transfer; and provided further that no transferee of a Limited Partner's
interest may be admitted to the Partnership as a substitute Limited Partner
without the consent of the General Partner.

                      (c)  Notwithstanding any other provision of this
Agreement, no transfer or other disposition of the interest of a Limited Partner
shall be permitted until the General Partner shall have received, or waived
receipt of, an opinion of counsel to the Partnership reasonably satisfactory to
it that the effect of such transfer or disposition would not:

                           (1)   result in a violation of the Securities Act;

                           (2)   require the Partnership to register as an
         investment company under the Investment Company Act of 1940, as
         amended;

                           (3)   require the Partnership, the General Partner or
         any partner of the General Partner to register as an investment adviser
         under the Investment Advisers Act of 1940, as amended;

                           (4)   result in a termination of the Partnership for
         tax purposes if the General Partner determines that such termination
         would result in a material adverse tax consequence to any of the
         Partners;

                           (5)   result in a violation of any law, rule, or
         regulation by the Limited Partner, the Partnership, the General Partner
         or any partner of the General Partner;

                           (6)   increase the number of Limited Partners;

                           (7)   cause the Partnership to be characterized as a
         "publicly traded partnership" taxable as a corporation (within the
         meaning set forth in Sections 512 and 7704(b) of the Code) or
         materially increase the risk that the Partnership will be so
         characterized.

               All costs associated with such opinion shall be borne by the
transferring Limited Partner.

               7.8.   Investment Opportunities; Conflicts of Interest
                      -----------------------------------------------

                      (a)  Christos M. Cotsakos and Thomas A. Bevilacqua (the
"Principals") are the current principal members of the General Partner. Subject
 ----------
to Paragraph 7.8(b), the Principals may serve as the general partners, sponsors,
principals of the general partners or investment advisers of other venture
funds. The Principals are employed by E*Trade and shall devote significant and
substantial time and effort to E*Trade. The Principals shall be free to conduct
any and all such activities.

                      (b)  So long as the Partnership is less than Two-Thirds
Invested, neither of the Principals may, directly or indirectly, organize or act
as a general partner or managing member of any other entity that is a private
equity fund. For purposes of this Agreement, the Partnership shall be deemed to
be "Two-Thirds Invested" when at least sixty-six and two-thirds percent (66-
    -------------------
2/3%) of the Partners' Capital Commitments (other than any Capital Commitments
that have been terminated) have been invested by the Partnership in Portfolio
Companies (with E*Trade's Capital Contribution made in Securities being deemed
to have been so invested), reserved for investments in such Portfolio Companies
based upon the General Partner's good faith estimate of the anticipated capital
requirements of each Portfolio Company, or paid or reserved for the payment of
reasonably anticipated partnership liabilities and obligations, including
payment of the Management Fee.

                      (c)  The General Partner and the members of the General
Partner shall be permitted to receive fees (director's, consulting, break-up,
financial advisory or other), commissions and other compensation (in whatever
form, including stock and options) from entities other than the Partnership,
including Portfolio Companies.

                      (d)  Except as expressly provided otherwise in this
Agreement, the Partners and the members and affiliates of the General Partner
may engage in, invest in or possess an interest in, business activities of every
kind and description, independently or with others.

                      (e)  The Limited Partners hereby agree that E*Trade may
have investment opportunities that are not made available to the Partnership. In
addition, the General Partner may offer the right to participate in investment
opportunities of the Partnership to other private investors, groups,
partnerships, or corporations. No Limited Partner shall be required to make any
investment opportunity available to the Partnership.

                      (f)  The General Partner may enter, on behalf of the
Partnership, into contracts, agreements, undertakings and transactions with any
Partners, or with any person, firm or corporation having any business, financial
or other relationship with any Partner, provided that such transactions with
such persons and entities are on terms no less favorable to the Partnership than
are generally afforded to unrelated third parties in comparable transactions.

                                 ARTICLE VIII

                DISSOLUTION AND LIQUIDATION OF THE PARTNERSHIP

               8.1.   Liquidation Procedures.  Upon termination of the
                      ----------------------
Partnership in accordance with Article II:

                      (a)  The affairs of the Partnership shall be wound up and
the Partnership shall be dissolved. The General Partner shall serve as the
liquidator; provided that in the event of a termination of the Partnership
pursuant to Paragraph 2.2(a),(b), or (c) another person or entity may be
designated by Two-Thirds in Interest of the Limited Partners to serve as
liquidator.

                      (b)  Distributions in dissolution may be made in cash or
in kind or partly in cash and partly in kind. Each Security (and each class of
Securities, or portion of a class of Securities having a tax basis per share or
unit different from other portions of such class) distributed in kind shall be
distributed ratably in accordance with the General Partner's and the Limited
Partners' Capital Accounts unless such distribution would result or there is a
material likelihood that such distribution would result (i) in a violation of a
law or regulation applicable to a Limited Partner or a tax penalty to a Limited
Partner, in which event, upon receipt by the General Partner of notice to such
effect, such Limited Partner may designate a different entity to receive the
distribution, or designate, subject to the approval of the General Partner, an
alternative distribution procedure or (ii) in a distribution of fractional
shares. Each such Security shall be valued at fair market value in accordance
with Paragraph 9.2 as of the date of distribution and shall be subject to
reasonable conditions and restrictions necessary or advisable in order to
preserve the value of the assets distributed, or for legal reasons.

                      (c)  The General Partner (or other liquidator) shall in
its sole discretion determine the most advantageous time for the Partnership to
sell investments or to make distributions in kind provided that any such sales
shall be made as promptly as is consistent with obtaining the fair value
thereof.

                      (d)  The proceeds of dissolution shall be applied to
payment of liabilities of the Partnership and distributed to the Partners in the
following order:

                           (1)   to the creditors of the Partnership in the
         order of priority established by law; and

                           (2)   to the Partners, in respect of the positive
         balances in their Capital Accounts, after all Capital Transaction Gain
         or Loss and Net Income or Loss (including amounts arising in connection
         with a distribution of Securities) has been allocated among the
         Partners.

               In the discretion of the General Partner, a pro rata portion of
the distributions that would otherwise be made to the Partners pursuant to this
Paragraph 8.1 may be withheld to provide a reasonable reserve for Partnership
liabilities (contingent or otherwise) and to reflect the unrealized portion of
any installment obligations owed to the Partnership, provided that such withheld
amounts (to the extent not used to pay partnership liabilities) shall be
distributed to the Partners as soon as practicable.

                                      26.
<PAGE>

               (e)  If the General Partner's Capital Account has a deficit
balance (after giving effect to all contributions, distributions and allocations
for all taxable years, including the year during which such liquidation occurs),
then except as otherwise required pursuant to Paragraph 8.2, the General Partner
shall have no obligation at any time to repay or restore to the Partnership all
or any part of any distribution made to it from the Partnership or make any
contribution to the capital of the Partnership with respect to such deficit. If
any Limited Partner has a deficit balance in his Capital Account (after giving
effect to all contributions, distributions and allocations for all taxable
years, including the year during which such liquidation occurs), then other than
required by law or Paragraph 10.14, such Limited Partner shall have no
obligation to repay or restore to the Partnership any distribution made to it
from the Partnership or make any contribution to the capital of the Partnership
with respect to such deficit, and such deficit shall not be considered a debt
owed to the Partnership or to any other person for any purpose whatsoever.

          8.2. Liability of General Partner to Return Excess Distributions. If
               -----------------------------------------------------------
after effecting the distributions provided for in this Article VIII the Excess
Distribution Amount is greater than zero, then the General Partner shall
forthwith contribute to the capital of the Partnership cash or Marketable
Securities (with any such contributed Marketable Securities being valued
pursuant to Paragraph 9.2 on the date of contribution) in an amount equal to the
lesser of (i) the Excess Distribution Amount, or (ii) the After-Tax Distribution
Amount. Such contribution shall be distributed to the Partners to the extent of
and in proportion to their positive Capital Account balances.

          For purposes of this Paragraph 8.2:

               (a)  The "After-Tax Distribution Amount" shall be equal to the
                         -----------------------------
General Partner Distributions less all federal, state and other jurisdictional
(including non-United States taxes) actual marginal tax liabilities that the
members of the General Partner have incurred by reason of having been members of
the General Partner, but only to the extent attributable to (i) items of taxable
income, gain, loss, deduction and credit allocated to the General Partner by the
Partnership and (ii) net capital gains realized by the General Partner or by
such members (offset by any capital losses realized by the General partner or by
such members) upon the sale or exchange of Securities distributed by the
Partnership to the General Partner (with such net capital gains being limited to
an amount based on the value as of the distribution date of the Securities
distributed). The After-Tax Distribution amount shall be increased by all
federal, state or other jurisdictional tax benefits actually realized by the
General Partner's members in the year of a contribution required by this
Paragraph 8.2 as a result of such contribution.

               (b)  The "Excess Distribution Amount" shall equal the lesser of
                         --------------------------
(i) the amount by which the General Partner Distributions exceed the sum of the
Total General Partner Net Gain or Loss plus the aggregate contributions made to
the Partnership by the General Partner or (ii) the amount of the General Partner
Distributions.

                                      27.
<PAGE>

               (c)  "Total General Partner Net Gain or Loss" shall be calculated
                     --------------------------------------
as follows:

                    (1)  First, the Partnership's aggregate Capital Transaction
     Gain for all accounting periods shall be netted against the Partnership's
     aggregate Capital Transaction Loss for all accounting periods and the
     result shall be multiplied by the sum of (x) twenty percent (20%) plus (y)
     eighty percent (80%) of the General Partner's Partnership Percentage. The
     resulting product shall be considered a positive number if such aggregate
     Capital Transaction Gain exceeded aggregate Capital Transaction Loss and a
     negative number if such aggregate Capital Transaction Loss exceeded
     aggregate Capital Transaction Gain;

                    (2)  Second, the Partnership's aggregate Net Income for all
     accounting periods shall be netted against the Partnership's aggregate Net
     Loss for all accounting periods and the result shall be multiplied by the
     General Partner's Partnership Percentage. The result shall be considered a
     positive number if such aggregate Net Income exceeded such aggregate Net
     Loss and a negative number if such aggregate Net Loss exceeded such
     aggregate Net Income;

                    (3)  Third, the amount computed in clause (2) shall be added
     to the amount computed in clause (1). If the result of such computation is
     a positive number it shall be considered Total General Partner Net Gain and
     if the result of such computation is a negative number it shall be
     considered Total General Partner Net Loss.

               (d)  "General Partner Distributions" shall equal the sum of all
                     -----------------------------
distributions received by the General Partner pursuant to Article VI and this
Article VIII.

               (e)  All in-kind distributions shall be valued as provided in
Paragraph 9.2 as of the date of the distribution.

               (f)  Only allocations and distributions made to the General
Partner in its capacity as general partner of the Partnership (including
allocations and distributions resulting from the General Partner's Capital
Contributions made in such capacity) shall be considered for purposes of the
foregoing computations (such distributions shall, however, in no way be
construed so as to include amounts paid or otherwise received by the General
Partner pursuant to Article V hereof).

               (g)  Each of the members of the General Partner shall be
severally, but not jointly, liable to the Partnership for any unpaid liability
of the General Partner determined pursuant to this Paragraph 8.2, based on their
relative distributions received from the General Partner. The Principals hereby
agree to obtain the written agreement of each member of the General Partner as
to the liability to the Partnership described in the preceding sentence.

          8.3. Liquidating Trust. In the discretion of the General Partner, any
               -----------------
Nonmarketable Securities and other assets that would otherwise be distributed to
the Partners pursuant to this Article VIII may be distributed to a trust
established for the benefit of the Partners for the purposes of holding and
liquidating such Nonmarketable Securities (and any other Partnership assets),
collecting amounts owed to the Partnership, and paying any contingent

                                      28.
<PAGE>

or unforeseen liabilities or obligations of the Partnership. The trustee of such
trust shall be the General Partner or other person appointed by a Two-Thirds in
Interest of the Limited Partners. During the term of the trust, any
Nonmarketable Securities held in the trust shall continue to be held until they
become Marketable Securities except to the extent otherwise determined by the
General Partner. Subject to the foregoing, the net assets of the trust shall be
distributed to the Partners from time to time, in the discretion of the General
Partner (or other trustee), in the same proportions as such assets would have
been distributed if they had continued to be held (and disposed of) by the
Partnership. The term of the trust shall be for no more than two years, subject
to two one-year extensions with the approval of Two-Thirds in Interest of the
Limited Partners.

                       FINANCIAL ACCOUNTING AND REPORTS

          9.1. Financial and Tax Accounting and Reports. The General Partner
               ----------------------------------------
shall cause the Partnership's tax returns and IRS Form 1065, Schedule K-1's, to
be prepared and delivered in a timely manner to the Limited Partners. The
General Partner shall use its best efforts to cause the Schedule K-1's for each
Fiscal Year to be delivered to the Limited Partners within ninety (90) days
after the end of the Fiscal Year. The books and records of the Partnership and
the General Partner shall be kept in accordance with the provisions of this
Agreement and otherwise in accordance with generally accepted accounting
principles consistently applied. The Partnership's financial statements for each
Fiscal Year shall be prepared in accordance with such principles consistently
applied and shall be audited at the end of each Fiscal Year by an independent
certified public accounting firm of recognized national standing selected by the
General Partner. The General Partner shall transmit to each Limited Partner as
soon as practicable after the close of each of the Partnership's Fiscal Years
(but in no event later than ninety (90) days after the end of each Fiscal Year),
beginning with the Fiscal Year ending December 31, 1999, the audited financial
statements of the Partnership accompanied by a report from the General Partner
to the Limited Partners, which shall include a status report on investments then
held, a valuation of each such investment, and a brief statement on the affairs
of the Partnership during the Fiscal Year then ended. In addition, the General
Partner shall, within a reasonable time following the completion of the report
referred to above and following reasonable notice to each Partner, hold an
annual meeting of the Partners at which the General Partner shall present the
affairs of the partnership and provide the Limited Partners with the opportunity
to ask questions and discuss the Partnership's affairs.

          9.2. Valuation of Securities and Other Assets Owned by the
               -----------------------------------------------------
Partnership.
-----------

               (a)  Subject to the specific standards set forth below, the
valuation of Securities and other assets and liabilities under this Agreement
shall be at fair market value, as determined by the General Partner in its
discretion. In determining the value of the interest of any Partner or in any
accounting between the Partners, no value shall be placed on the goodwill or the
name of the Partnership.

                                      29.
<PAGE>

               (b)  The following criteria shall be used for determining the
fair market value of Securities.

                    (1)  Securities not subject to legal or contractual
     restrictions on free marketability:

                         (A)  If traded on one (1) or more securities exchanges
          or on NASDAQ, the value of each Security shall be deemed to be the
          average closing price of such Security for the five (5) trading days
          immediately preceding the valuation date as reported in the Wall
          Street Journal or another nationally recognized publication or service
          that reports such data for the valuation date.

                         (B)  If actively traded over-the-counter (but not on
          NASDAQ), the value shall be deemed to be the closing bid price of such
          Security for the five (5) trading days immediately preceding the
          valuation date.

                         (C)  If there is no active public market, the General
          Partner shall make a determination of the fair market value on the
          valuation date, taking into consideration the tax basis of the
          Securities, developments concerning the issuing company subsequent to
          the acquisition of the Securities, the pricing of other private
          placements of Securities by the issuer, the price of the Securities of
          other companies comparable to the issuer, any financial data and
          projections of the issuing company provided to the General Partner and
          such other factor or factors as the General Partner may deem relevant.

                    (2)  In the case of Securities subject to legal or
     contractual restrictions on free marketability, appropriate adjustments to
     the value determined under Paragraph 9.2(b)(1) above shall be made to
     reflect the effect of the restrictions on transfer.

                    (3)  If the General Partner in good faith determines that,
     because of special circumstances, the valuation methods set forth in this
     paragraph do not fairly determine the value of a Security, the General
     Partner shall make such adjustments or use such alternative valuation
     method as it deems appropriate.

          9.3. Supervision; Inspection of Books. Proper and complete books of
               --------------------------------
account of the affairs of the Partnership shall be kept under the supervision of
the General Partner at the principal office of the Partnership. Such books shall
be open to inspection by a Limited Partner, at any reasonable time, upon
reasonable notice, during normal business hours. A copy of a current list of
Partners, with telephone numbers, shall be provided to any Partner upon request.
The General Partner shall provide any Limited Partner with information
reasonably requested by such Limited Partner for any purpose reasonably related
to such Limited Partner's interest as a partner in the Partnership.

          9.4. Quarterly Reports. Beginning with the first Fiscal Quarter
               -----------------
commencing after the date of this Agreement, the General Partner shall transmit
to each Limited Partner within forty-five (45) days after the close of each of
the first three (3) Fiscal Quarters of each Fiscal Year, financial statements of
the Partnership prepared in accordance with the terms of this

                                      30.
<PAGE>

Agreement and otherwise in accordance with generally accepted accounting
principles from its books without audit and subject to year-end adjustments, a
valuation of each of the Partnership's investments, a valuation of the
Partnership interest of the Limited Partner (based upon the interest of the
Limited Partner in the Partnership's assets), the amount of each Partner's
Capital Account and a list of investments then held with a brief description of
each Portfolio Company.

          9.5.  Confidentiality. Each Limited Partner agrees to maintain the
                ---------------
confidentiality of the Partnership's records and affairs, agrees not to provide
to any other person copies of any financial statements, tax returns or other
records or reports provided or made available to such Limited Partner, and
agrees not to disclose to any other person any information contained therein
(including, without limitation, information respecting Portfolio Companies),
without the express prior written consent of the General Partner; provided, that
any Limited Partner may make disclosure and may provide financial statements,
tax returns and other records (i) to its accountants, internal and external
auditors, legal counsel, financial advisors and other fiduciaries and
representatives as long as it instructs such persons to maintain the
confidentiality thereof and not to disclose to any other person any information
contained therein, (ii) to potential transferees of such Limited Partner's
Partnership interest who agree in writing, for the benefit of the Partnership,
to maintain the confidentiality thereof, but only after reasonable advance
notice to the Partnership, (iii) if, and to the extent, required by law,
including judicial or administrative order (provided, that, to the extent
possible, the Partnership is given prior notice to enable it to seek a
protective order or similar relief), (iv) in order to enforce rights under this
Agreement, (v) to any regulatory body having jurisdiction over the Limited
Partner and such of its advisors as need to or customarily have access to such
information, and (vi) to any of its equity holders, provided that it shall use
all commercially reasonable efforts to cause such persons to observe the
provisions of this Paragraph 9.5.

          10.4. Governing Law.  This Agreement shall be governed by and
                -------------
construed under the laws of the State of Delaware as applied to agreements among
Delaware residents made and to be performed entirely within Delaware.

          10.5. Notices. Any notice or other communication that a Partner
                -------
desires to give to another Partner shall be in writing, and shall be deemed
effectively given upon personal

<PAGE>

delivery or upon deposit in any United States mail box, by registered or
certified mail, postage prepaid, or upon transmission by telegram or telecopy,
addressed to the other Partner at the address shown on Exhibit A or at such
other address as a Partner may designate by fifteen (15) days' advance written
notice to the other Partners.

          10.6.  Power of Attorney. By signing this Agreement, each Limited
                 -----------------
Partner designates and appoints the General Partner its true and lawful
attorney, in its name, place and stead to make, execute, sign, and file such
instruments, documents, or certificates that may from time to time be required
of the Partnership by the laws of the United States of America, the laws of the
State of Delaware, or any other state in which the Partnership shall conduct its
investment activities in order to qualify or otherwise enable the Partnership to
conduct its affairs in such jurisdictions; provided, however, that in no event
shall the General Partner be deemed to have the authority under this Paragraph
10.6 to take any action that would result in any Limited Partner losing the
limitation on liability afforded hereunder. Such attorney is not hereby granted
any authority on behalf of the Limited Partner to amend this Agreement except
that as attorney for each Limited Partner, the General Partner shall have the
authority to amend this Agreement and the Certificate of Limited Partnership as
may be required to effect:

                 (a) Admissions of additional partners pursuant to Paragraph 7.6
or 7.7 above; or

                 (b) Transfers of Limited Partnership interests pursuant to
Paragraph 7.7 above.

          10.7.  Amendment. This Agreement (and any exhibits to this Agreement)
                 ---------
may be amended only with the written consent of the General Partner and Majority
in Interest of the Limited Partners. No amendment shall, however, (i) increase
the Capital Commitment of a Limited Partner or modify the allocation of Capital
Transaction Gain or Loss or Net Income or Loss or the distributions allocable to
any Limited Partner without the written consent of such Limited Partner, (ii)
increase the Management Fee or alter or waive the terms of Paragraph 8.2 without
the unanimous consent of the Limited Partners, (iii) alter or waive the terms of
this Paragraph 10.7(a), or (iv) alter or waive the terms of Paragraphs 7.6,
10.14, or 10.17 without the written consent of each affected Limited Partner.
Any proposed amendment that would change the requisite percentage of Limited
Partner interests required to take any action shall require the approval of such
existing requisite percentage. The General Partner shall promptly furnish copies
of all amendments to this Agreement and the Partnership's Certificate of Limited
Partnership to all Partners.

          10.8.  Effective Date. The Limited Partnership Agreement shall be
                 --------------
effective on the date set forth in the first paragraph of this Agreement.

          10.9.  Entire Agreement.  This Agreement constitutes the entire
                 ----------------
agreement of the Partners and supersedes all prior agreements between the
Partners with respect to the Partnership.

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

                                      32.
<PAGE>

               10.11. Partnership Name. The Partnership shall have the exclusive
                      ----------------
right to use the Partnership name (and any name under which the Partnership
shall elect to conduct its affairs) as long as the Partnership continues.

               10.12. Exculpation. Neither the General Partner, nor its members,
                      -----------
employees or affiliates shall be liable to a Limited Partner or the Partnership
for honest mistakes of judgment, or for action or inaction, taken reasonably and
in good faith for a purpose that was reasonably believed to be in the best
interests of the Partnership, or for losses due to such mistakes, action, or
inaction, or to the negligence or dishonesty of any employee, broker, or other
agent of the Partnership or the General Partner, provided that such employee,
broker, or agent was selected, engaged or retained and supervised with
reasonable care. This Paragraph 10.12 shall not extend to any action which
constitutes fraud, willful misconduct or gross negligence. The General Partner
may consult with counsel and accountants in respect of Partnership affairs and
be fully protected and justified in any action or inaction that is taken in
accordance with the advice or opinion of such counsel or accountants, provided
that they shall have been selected with reasonable care. Notwithstanding any of
the foregoing to the contrary, the provisions of this Paragraph 10.12 and of
Paragraph 10.13 hereof shall not be construed so as to relieve (or attempt to
relieve) any person of any liability by reason of recklessness or intentional
wrongdoing or to the extent (but only to the extent) that such liability may not
be waived, modified or limited under applicable law, but shall be construed so
as to effectuate the provisions of this Paragraph 10.12 and of Paragraph 10.13
to the fullest extent permitted by law.

               10.13. Indemnification. The Partnership agrees to indemnify, out
                      ---------------
of the assets of the Partnership only, the General Partner, the members of the
General Partner and their agents, employees and affiliates (and each such
person's heirs and legal and personal representatives) to the fullest extent
permitted by law and to save and hold them harmless from and in respect of all
(a) reasonable fees, costs, and expenses paid in connection with or resulting
from any claims, actions, or demands against the General Partner, the members of
the General Partner, the Partnership, or their agents or affiliates to the
extent that they arise out of or in any way relate to the Partnership, its
properties, business, or affairs and (b) such claims, actions, and demands and
any losses or damages resulting from such claims, actions, and demands,
including amounts paid in settlement or compromise (if recommended by attorneys
for the Partnership) of any such claim, action or demand; provided, however,
that this indemnity shall not extend to any action which constitutes fraud,
willful misconduct or gross negligence. Any person receiving an advance with
respect to expenses shall be required to agree to return such advance to the
Partnership in the event it is subsequently determined that such person was not
entitled to indemnification hereunder. Any indemnified party shall promptly seek
recovery under any other indemnity or any insurance policies by which such
indemnified party may be indemnified or covered or from any Portfolio Company in
which the Partnership has an investment, as the case may be. No payment or
advance may be made to any person under this Paragraph 10.13 to any person who
may have a right to any other indemnity (by insurance or otherwise) unless such
person shall have agreed, to the extent of any other recovery, to return such
payments or advances to the Partnership.

               10.14. Limitation of Liability of the Limited Partners. No
                      -----------------------------------------------
Limited Partner shall be bound by, nor be personally liable for, the expenses,
liabilities, or obligations of the Partnership in excess of the balance of such
Partner's Capital Commitment to the Partnership.

                                      33.
<PAGE>

               10.15. Arbitration. Any controversy or claim arising out of or
                      -----------
relating to this Agreement, or the breach hereof, shall be settled by
arbitration in San Francisco, California, in accordance with the rules, then
obtaining, of the American Arbitration Association. Any award shall be final,
binding and conclusive upon the parties. A judgment upon the award rendered may
be entered in any court having jurisdiction thereof.

               10.16. Tax Matters Partner. The General Partner shall be the
                      -------------------
Partnership's Tax Matters Partner ("TMP"). The TMP may be removed by Two-Thirds
                                    ---
in Interest of the Limited Partners. Upon the removal, dissolution or Bankruptcy
of the TMP, a successor TMP shall be elected by Two-Thirds in Interest of the
Limited Partners. The TMP shall employ experienced tax counsel to represent the
Partnership in connection with any audit or investigation of the Partnership by
the Internal Revenue Service ("IRS") and in connection with all subsequent
                               ---
administrative and judicial proceedings arising out of such audit. The fees and
expenses incurred by the TMP in serving as the TMP shall be Partnership expenses
pursuant to Paragraph 5.2 and shall be paid by the Partnership. Notwithstanding
the foregoing, it shall be the responsibility of the General Partner and of each
Limited Partner, at their expense, to employ tax counsel to represent their
respective separate interests. If the TMP is required by law or regulation to
incur fees and expenses in connection with tax matters not affecting each of the
Partners, then the TMP may, in its sole discretion, seek reimbursement from or
charge such fees and expenses to the Capital Accounts of those Partners on whose
behalf such fees and expenses were incurred. The TMP shall keep the Limited
Partners informed of all administrative and judicial proceedings, as required by
Section 6223(g) of the Code, and shall furnish a copy of each notice or other
communication received by the TMP from the IRS to each Limited Partner, except
such notices or communications as are sent directly to such Partner by the IRS.
The relationship of the TMP to the Limited Partners is that of a fiduciary, and
the TMP has a fiduciary obligation to perform its duties as TMP in such manner
as will serve the best interests of the Partnership and all of the Partnership's
partners. To the fullest extent permitted by law, the Partnership agrees to
indemnify the TMP and its agents and save and hold them harmless, from and in
respect to all (i) reasonable fees, costs and expenses in connection with or
resulting from any claim, action, or demand against the TMP, the General Partner
or the Partnership that arise out of or in any way relate to the TMP's status as
TMP for the Partnership, and (ii) all such claims, actions, and demands and any
losses or damages therefrom, including amounts paid in settlement or compromise
of any such claim, action, or demand; provided that this indemnity shall not
extend to conduct by the TMP determined (i) not to have been undertaken in good
faith to promote the best interests of the Partnership or (ii) to have
constituted recklessness, fraud, gross negligence or intentional wrongdoing by
the TMP.

               10.17. Taxation as Partnership. The General Partner, while
                      -----------------------
serving as such, agrees to use its best efforts to avoid taking any action that
would cause the Partnership to be classified as other than a partnership or to
be taxable as a corporation for federal income tax purposes. In the event the
Partnership should ever be taxable as a corporation, any resulting tax imposed
on the Partnership shall be treated as a reduction in Net Income or an increase
in Net Loss.

               10.18. Deliveries of Opinions. In the event that any opinion is
                      ----------------------
required hereunder from a Limited Partner, the General Partner will reasonably
cooperate with such Limited Partner's counsel to provide factual information in
the possession of the General Partner which

                                      34.
<PAGE>

information is necessary to allow such counsel to provide the opinion. Any
expense related thereto shall be borne by such Limited Partner.

                                  ARTICLE XI

                    MISCELLANEOUS TAX COMPLIANCE PROVISIONS

               11.1.  Substantial Economic Effect. The provisions of Article IV
                      ---------------------------
and the other provisions of this Agreement relating to the maintenance of
Capital Accounts and procedures upon liquidation of the Partnership are intended
to comply generally with the provisions of Treasury Regulation Section 1.704-1,
and shall be interpreted and applied in a manner consistent with such
Regulations and, to the extent the subject matter thereof is otherwise not
addressed by this Agreement, the provisions of Treasury Regulations Section
1.704-1 are hereby incorporated by reference unless the General Partner shall
determine that such incorporation will result in economic consequences
inconsistent with the economic arrangement among the Partners as expressed in
this Agreement. In the event the General Partner shall determine that it is
prudent to modify the manner in which the Capital Accounts, or any debits or
credits thereto, are computed or allocated or the manner in which distributions
and contributions upon liquidation (or otherwise) of the Partnership (or any
Partner's interest therein) are effected in order to comply with such
Regulations and other applicable tax laws, or to assure that the Partnership is
treated as a partnership for tax purposes, or to achieve the economic
arrangement of the Partners as expressed in this Agreement, then notwithstanding
Paragraph 10.7 hereof, the General Partner may make such modification, provided
that it is not likely to have more than an insignificant detrimental effect on
the tax consequences and total amounts distributable to any Limited Partner
pursuant to Articles VI and VIII as applied without giving effect to such
modification. The General Partner shall also (i) make any adjustments that are
necessary or appropriate to maintain equality between the Capital Accounts of
the Partners and the amount of Partnership capital reflected on the
Partnership's balance sheet, as computed for book purposes pursuant to this
Agreement, in accordance with Regulations Section 1.704-1(b)(2)(iv)(g), and (ii)
make any appropriate modifications in the event unanticipated events (such as
the incurrence of nonrecourse indebtedness) might otherwise cause the
allocations under this Agreement not to comply with Treasury Regulations Section
1.704, provided in each case that the General Partner determines that such
adjustments or modifications shall not result in economic consequences
inconsistent with the economic arrangement among the Partners as expressed in
this Agreement.

               11.2.  Other Allocations. Notwithstanding the provisions of
                      -----------------
Article IV, the allocations provided therein shall be subject to the following
exceptions:

                      (a)  In the event any Partner's Capital Account has an
Unadjusted Excess Negative Balance (as defined in subparagraph (f)) at the end
of any Fiscal Year, such Partner will be reallocated items of Capital
Transaction Gain and Net Income for such Fiscal Year (and, if necessary, future
Fiscal Years) in the amount necessary to eliminate such Unadjusted Excess
Negative Balance as quickly as possible.

                      (b)  In the event any Partner unexpectedly receives any
adjustments, allocations or distributions described in Treasury Regulations
Sections 1.704-1(b)(2)(ii)(d)(4) through (d)(6), items of Capital Transaction
Gain and Net Income shall be specially allocated to

                                      35.
<PAGE>

such Partner's Capital Account in an amount and manner sufficient to eliminate,
to the extent required by Treasury Regulations Section 1.704-1(b)(2)(ii)(d), the
Excess Negative Balance (as defined in subparagraph (e)) in such Partner's
Capital Account created by such adjustments, allocations or distributions as
quickly as possible. This subparagraph (b) is intended to and shall in all
events be interpreted so as to constitute a "qualified income offset" within the
                                             -----------------------
meaning of Treasury Regulations Section 1.704-1(b)(2)(ii)(d).

                      (c)  A Partner's Capital Account shall not be allocated
any item of Capital Transaction Loss or Net Loss to the extent such allocation
would cause such Capital Account to have an Excess Negative Balance (as defined
in subparagraph (e)).

                      (d)  Any special allocations pursuant to this Paragraph
11.2 shall be taken into account as soon as possible in computing subsequent
allocations, so that over the term of the Partnership the net amount of any
items so allocated and the profit, gain, loss, income and expense and all other
items allocated to each Partner shall, to the extent possible, be equal to the
net amount that would have been allocated to each such Partner if such original
allocations pursuant to this Paragraph 11.2 had not occurred.

                      (e)  For purposes of this Paragraph 11.2, "Excess Negative
                                                                 ---------------
Balance" shall mean the excess of the negative balance in a Partner's Capital
-------
Account (computed with any adjustments which are required for purposes of
Treasury Regulations Section 1.704-1(b)(2)(ii)(d)) over the amount such Partner
is obligated to restore to the Partnership (computed under the principles of
Treasury Regulations Section 1.704-1(b)(2)(ii)(c)) inclusive of any addition to
such restoration obligation pursuant to application of the provisions of
Treasury Regulations Sections 1.704-2), or any successor provisions thereto.

                      (f)  For purposes of this Paragraph 11.2 "Unadjusted
                                                                ----------
Excess Negative Balance" shall have the same meaning as Excess Negative Balance,
-----------------------
except that the Unadjusted Excess Negative Balance of a Partner shall be
computed without effecting the reductions to such Partner's Capital Account
which are described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d).

               11.3.  Income Tax Allocations.
                      ----------------------

                      (a)  Except as otherwise provided in this Paragraph 11.3
or as otherwise required by the Code and the rules and Treasury Regulations
promulgated thereunder, Partnership income, gain, loss, deduction, or credit for
income tax purposes shall be allocated in the same manner the corresponding book
items are allocated pursuant to this Agreement.

                      (b)  In accordance with Code Section 704(c) and the
Treasury Regulations thereunder, income, gain, loss and deduction with respect
to any asset contributed to the capital of the Partnership shall, solely for tax
purposes, be allocated between the Partners so as to take account of any
