                                  ORGANIZATION

         SECTION 2.01. FORMATION OF LIMITED LIABILITY COMPANY. The Members agree
to carry on a limited liability company (the "COMPANY") subject to the terms of
this Agreement pursuant to and in accordance with the Delaware Limited Liability
Company Act, as amended (the "DELAWARE ACT").

         SECTION 2.02. FIRM NAME; REGISTERED AND PRINCIPAL OFFICE. The name of

         SECTION 2.03. PURPOSES. The principal purpose of the Company is to
locate, analyze and invest in equity and equity-oriented securities, including
securities convertible into or exercisable or exchangeable for equity securities
and, in furtherance thereof, (a) to hold, and to sell, distribute or otherwise
dispose of its Portfolio Securities in accordance with this Agreement over such
period as the Advisory Committee, after soliciting the recommendation of the
Managing Member, determines to be in the best interest of the Members, and (b)
subject to the terms and provisions of this Agreement, otherwise to engage in
any lawful activity for which limited liability companies may be organized under
the laws of the State of Delaware.

         SECTION 2.04. POWERS. Subject to all of the terms and provisions
hereof, and consistent with the purposes of the Company, the Company shall have
the following powers:

         (a) to purchase, invest in and sell securities and interests in
securities of every kind, including, without limitation, capital stock,
partnership interests, limited liability company membership interests, bonds,
notes, debentures, trust receipts, and other obligations, as well as rights and
options to purchase and sell securities;

         (b) to make and perform all contracts and engage in all activities and
transactions necessary or advisable to carry out the purposes of the Company,
including, without limitation, the purchase, sale, transfer, pledge and exercise
of all rights, privileges and incidents of ownership or possession with respect

and the Class A Member shall be treated as partners in a partnership for such
purposes within the meaning of Section 761(b) of the Code. The Members agree

Agreement appropriately reflects the contributions and the activities of the
Members on behalf of the Company in their respective capacities as "partners" in
a partnership within the meaning of Subchapter K of the Code. Further, the
Members intend, and the Managing Member shall use its best efforts to ensure,
that the Company will be treated as an "investment partnership" as such term is

promulgated thereunder.

required to preserve the limited liability of the Members in any jurisdiction in

Committee, any transaction between the Managing Member, the Principals or their
Affiliates and the Company or any Portfolio Company shall be on terms no less
favorable to the Company or the Portfolio Company, as the case may be, than are
generally afforded to unrelated third parties in comparable transactions.

         SECTION 3.07.  DUTY OF CARE.

         (a) It is recognized that decisions concerning investments or potential
investments involve the exercise of judgment and the risk of loss. The Managing
Member and the Principals shall exercise their best judgment in making
investments on behalf of the Company and in carrying out their other obligations
hereunder, and the Managing Member, its members, employees, agents and

<PAGE>   9


out of any investment or any other action or omission of the Managing Member,
any member, employee, agent or Affiliate of the Managing Member or any
Principal, provided that (1) the Managing Member, member, employee, agent or
Affiliate of the Managing Member, or such Principal acted in good faith and in a
manner such Person reasonably believed to be in, or not opposed to, the best
interest of the Company and, with respect to any criminal action or proceeding,
had no reasonable cause to believe such Person's conduct was unlawful, and (2)
such course of conduct did not constitute gross negligence or willful misconduct
of the Managing Member, member, employee, agent or Affiliate of the Managing
Member or such Principal; nor shall the Managing Member, any member, employee,
agent of the Managing Member or any Affiliate of the Managing Member or any
Principal be liable for the negligence, whether of omission or commission,
dishonesty or bad faith of any employee, broker or other agent of the Company
selected and supervised by the Managing Member (or any member, employee or agent
of the Managing Member or any Affiliate of the Managing Member or any Principal)
with reasonable care. The Managing Member, the members, employees and agents and
the Affiliates of the Managing Member and the Principals shall be fully
protected and justified with respect to any action or omission taken or suffered
by any of them in good faith if such action or omission is taken or suffered in
reliance upon and in accordance with the opinion or advice as to matters of law
of legal counsel, or as to matters of accounting of accountants, selected by any
of them with reasonable care.

         SECTION 3.08. INVESTMENT AND OTHER LIMITATIONS. The Company shall not,
without the prior approval of the Advisory Committee, invest in the securities
issued by any entity. The Managing Member shall sell, transfer or otherwise
dispose of a Portfolio Security as directed by the Advisory Committee; provided

modified, terminated or amended without the written consent of the Advisory
Committee. If a "Cause Event", as defined in the GPLLC Agreement, occurs with
respect to a member of the Managing Member, the Managing Member shall cause such
member's interest in the Managing Member to be converted into a "Retired
Member's interest", as defined in the GPLLC Agreement, if, as and when directed
by the Advisory Committee.

         SECTION 3.09. BORROWING; GUARANTEES. Without the prior approval of the
Advisory Committee, the Managing Member may not cause the Company to borrow
money, pledge any assets of the Company, grant a lien on such assets, or
otherwise incur indebtedness or guaranty the indebtedness of Portfolio
Companies.

         SECTION 3.10. CLASSIFICATION AS PARTNERSHIP. The Managing Member agrees
that it (a) will not cause or permit the Company to elect (1) to be excluded
from the provisions of Subchapter K of the Code or (2) to be treated as a
corporation for federal income tax purposes; (b) will cause the Company to make
any election reasonably determined to be necessary or appropriate in order to
ensure the treatment of the Company as a partnership for federal income tax
purposes; (c) will cause the Company to file any required tax returns in a
manner consistent with its treatment as a partnership for federal income tax
purposes; and (d) has not taken, and

                                      -5-

<PAGE>   10


will not take, any action that would be inconsistent with the treatment of the
Company as a partnership for such purposes.


                                   ARTICLE IV

                                 CLASS A MEMBER

the Company shall be limited to any unpaid capital contributions which it agreed
to make to the Company, except as otherwise provided under the Delaware Act or
as expressly provided in this Agreement.

         SECTION 4.03. NO CONTROL OF COMPANY. The Class A Member, in its
capacity as such, shall not take any part in the control of the affairs of the
Company, shall not undertake any transactions on behalf of the Company, and
shall not have any power to sign for or to bind the Company.

         SECTION 4.04. DISSOLUTION OR BANKRUPTCY. The bankruptcy, liquidation or
dissolution of the Class A Member shall not result in the termination of the
Company, but the rights and obligations of the Class A Member under this
Agreement shall accrue to the Class A Member's successor or legal
representative. Except as expressly provided in this Agreement, no other event
affecting the Class A Member (including but not limited to insolvency) shall
affect this Agreement.

SCHEDULE C, with the Managing Member (as amended from time to time, the
"Management Agreement).

         SECTION 5.02. FEES AND COMMISSIONS FROM PORTFOLIO COMPANIES. The
Managing Member and its Affiliates (including the Principals) shall be permitted
to receive fees, commissions and other compensation from Portfolio Companies,
provided, however, that any director's, consulting, monitoring, investment
banking, transaction or break-up fees or other remuneration (including, without
limitation, proceeds from the disposition of any stock option received in
connection with service as a director, consultant or investment banker) paid to
the Managing Member, a Principal, or any Affiliate of the Managing Member or
Principal by or with respect to a Portfolio Company for services rendered shall
be received by the Managing Member or any such Affiliate as an agent of the
Company and remitted to the Company immediately or at such other time or times
as determined by the Managing Member with the approval of the Advisory
Committee. Any Person receiving such Portfolio Company remuneration hereby
agrees to use its or his best efforts to ensure that the Company, rather than
such Person, is treated for tax purposes as earning such remuneration.


                                   ARTICLE VI

         (f) to approve the selection of the Company's independent public
accountants;

         (g) to resolve any questions relating to potential conflicts of
interest between the Managing Member, a Principal or an Affiliate of either such
Person on the one hand, and the Company on the other hand;

         (h) to resolve any other issues brought to the Advisory Committee by
the Managing Member and to perform such other functions as are provided for
under this Agreement; and

         (i) to hire and replace such attorneys, accountants or other advisors
on behalf of the Company as the Advisory Committee may determine.

         SECTION 6.04. VALUATION PROCEDURES. Whenever valuation of Company
assets or net assets is required by this Agreement, the Managing Member shall
submit to the Advisory Committee for approval its proposed valuation of Company
assets, including therewith a statement setting forth the basis of valuation of
each such asset. If the Advisory Committee fails to approve the valuations
proposed by the Managing Member within fifteen (15) business days following
submission by the Managing Member, then the managers of the Managing Member will
meet with the Advisory Committee, either in person or by telephone conference,
to review the proposed valuations and to consider changes therein proposed by
the Advisory Committee. If the Managing Member and the Advisory Committee cannot
agree on the valuation of Company assets within thirty (30) business days after
the original submission by the Managing Member, then the alternative valuations
proposed by the Advisory Committee shall be deemed accepted as the valuation of
the Company assets.

         SECTION 6.05. VOTING; RULES AND PROCEDURES. All approvals,
disapprovals, vetoes and other actions taken by the Advisory Committee shall be
authorized by a majority of the Committee members then holding office, including
the Chairman. The Advisory Committee shall have the authority to adopt rules and
procedures, not inconsistent with this Agreement, relating to the conduct of its
affairs.

         SECTION 6.06. DUTY OF CARE. The members of the Advisory Committee shall
exercise their best judgment in carrying out their functions for the Company. No
member of the Advisory Committee shall be liable to the Company or to any Member
for any loss suffered by the Company or any Member which arises out of any
action or omission of such member, provided that (1) such member acted in good
faith and in a manner such Person reasonably believed to be in, or not opposed
to, the best interest of the Company and, with respect to any criminal action or
proceeding, had no reasonable cause to believe such Person's conduct was

                                      -8-

<PAGE>   13


unlawful, and (2) such course of conduct did not constitute gross negligence or
willful misconduct of such member. The Advisory Committee and each member
thereof shall be fully protected and justified with respect to any action or
omission taken or suffered by any of them in good faith if such action or
omission is taken or suffered in reliance upon and in accordance with the
opinion or advice as to matters of law of legal counsel, or as to matters of
accounting of accountants, selected by any of them with reasonable care. In
addition, each member of the Advisory Committee shall be entitled to
indemnification by the Company to the extent provided in Article XVI hereof.

                             CAPITAL OF THE COMPANY

         SECTION 7.01.  CAPITAL CONTRIBUTIONS.

         (a) Each Member's initial capital contribution shall be due on the date
determined by the Advisory Committee. The amount of the Members' initial capital
contributions shall be determined by the Managing Member with the consent of the
Advisory Committee. Each Member's initial capital contribution shall be made,
with the approval of the Advisory Committee, (i) in cash, (ii) in securities of
entities that would be treated as Portfolio Companies hereunder if the Company,
rather than the Member, had acquired such securities directly from the issuer,
or (iii) in a combination of the foregoing. The Managing Member's initial
capital contribution shall be made in an amount equal to 1% of the aggregate
capital contribution due from all Members (including the Managing Member).

         (b) Each Member shall make additional contributions to the capital of
the Company ("ADDITIONAL CAPITAL CONTRIBUTIONS"), upon no less than three (3)
business days' prior written notice from the Managing Member, solely for the
purpose of allowing the Company to make investments in Portfolio Securities
approved by the Advisory Committee pursuant to Section 3.08. Each contribution
notice shall set forth the date on which the related Additional Capital
Contribution is due. The amount of capital required to be contributed by each
Member on each occasion of a capital contribution shall be computed by the
Managing Member so that the Class A Member contributes 99% of the aggregate
capital contribution to be made by all Members at such time and the Managing
Member contributes 1% of the aggregate capital contribution to be made by all
Members at such time. A Member may not make less than the full amount of an
Additional Capital Contribution and all Additional Capital Contributions shall
be made in cash in United States dollars, unless otherwise approved by the
Advisory Committee.

         (c) In the event that a Member makes all or a portion of its initial
capital contribution to the Company by contributing securities (the "CONTRIBUTED
SECURITIES"), such securities shall be credited to the Member's Capital Account,
as such term is defined in Article VIII hereof, at their respective Gross Asset
Values. The books and records of the Company, including for this purpose the
Capital Account of the Member, shall reflect such Gross Asset Value. SCHEDULE D
shall set forth the Gross Asset Values of any Contributed Securities and any
Contributed Securities Interest applicable to such Contributed Securities.

<PAGE>   14


         SECTION 7.02. NO INTEREST OR WITHDRAWALS. No interest shall accrue on
any capital contribution made by a Member, and no Member shall have the right to
withdraw or to be repaid any of its capital contributions so made, except as
specifically provided in this Agreement.

         SECTION 7.03. MINIMUM CAPITAL CONTRIBUTION OF MANAGING MEMBER.
Notwithstanding any other provision of this Agreement, the Managing Member shall
contribute cash (unless otherwise agreed to by the Advisory Committee) to the
Company at such times and in such amounts as necessary to ensure that the
paid-in capital contributions of the Managing Member are at all times equal to
1% of the aggregate paid-in capital contributions of all Members at such time.


                                  ARTICLE VIII

                                    ACCOUNTS

         SECTION 8.01. CAPITAL ACCOUNTS. There shall be established on the books
of the Company a capital account (the "CAPITAL ACCOUNT") for each Member that
shall consist of such Member's initial capital contribution to the Company and
that shall be:

         (a) Increased by (1) any Additional Capital Contributions made to the
Company by such Member pursuant to this Agreement and (2) any amounts from time
to time in the nature of income or gain added to the Capital Account of such
Member pursuant to Article IX or APPENDIX B; and

         (b) Decreased by (1) any distributions made to such Member and (2) any
amounts in the nature of loss, deduction or expense subtracted from the Capital
Account of such Member pursuant to Article IX or Appendix B.

         SECTION 8.02. ACCOUNTING FOR DISTRIBUTIONS IN KIND. For purposes of
maintaining Capital Accounts when Company property is distributed in kind:

         (a) The Company shall treat such property as if it had been sold for
its Gross Asset Value on the date of distribution;

         (b) Any difference between the Gross Asset Value as so determined and
the Cost of such property shall constitute Net Gain or Loss and shall be
allocated to the Capital Accounts of the Members pursuant to Article IX; and

         (c) The Capital Account of any Member receiving a distribution in kind
shall be reduced by an amount equal to the fair market value of such property on
the date of distribution (net of any liabilities secured by such distributed
property that such Member is considered to assume or take subject to under
Section 752 of the Code).

         SECTION 8.03. COMPLIANCE WITH TREASURY REGULATIONS. To the extent
consistent with Section 9.06, the foregoing provisions and the other provisions
of this Agreement relating to the maintenance of Capital Accounts are intended
to comply with Section 704(b) of the Code and Treasury Regulations Section
1.704-1(b), and shall be interpreted and applied in a manner consistent with
such regulations. In the event that the Advisory Committee shall determine that
it is prudent to modify the manner in which the Capital Accounts, or any debits
or credits thereto, are computed in order to comply with such regulations, the
Advisory Committee may make such modification.

                                   ARTICLE IX

                                   ALLOCATIONS

         SECTION 9.01. ALLOCATIONS OF NET GAIN. Except as provided in Section
9.05, as of the end of each fiscal year of the Company and after giving effect
to the special allocations set forth in Sections 9.03 and 9.04 and APPENDIX B,
the Net Gain (if any) of the Company for such fiscal year shall be allocated to
the Capital Accounts of the Members as follows (provided, however, that the
Class A Member shall be entitled at such times and in the manner determined by
the Advisory Committee, to a priority allocation of Net Gain, in an amount equal
to the aggregate amount of Contributed Securities Interest, so as to ensure that
the balance in its Capital Account reflects the Contributed Securities
Interest):

         (a) First, to all Members, in proportion to the respective amounts of
Net Loss (if any) previously allocated to each such Member pursuant to Section
9.02(d) and not offset by prior allocations of Net Gain made pursuant to this
Section 9.01(a), an amount of Net Gain equal to the aggregate amount of such Net
Loss;

         (b) Second, to all Members, in proportion to their respective
Preferential Return Allocations, an amount of Net Gain equal to the aggregate
amount of all such Preferential Return Allocations;

         (c) Third, to the Class A Member, an amount of Net Gain equal to the
Class A Member's Make-Whole Amount; and

         (d) Fourth, 80% to all Members in proportion to their respective
Contributions and 20% to the Managing Member.

         SECTION 9.02. ALLOCATIONS OF NET LOSS. Except as provided in Section
9.05, as of the end of each fiscal year of the Company and after giving effect
to the special allocations set forth in Sections 9.03 and 9.04 and APPENDIX B,
the Net Loss (if any) of the Company for such fiscal year shall be allocated to
the Capital Accounts of the Members as follows (provided, however, that the
Advisory Committee may in its discretion adjust the allocations of Net Loss
hereunder in a manner consistent with the economic agreement between the Members
with respect to Contributed Securities Interest):

                                      -11-

<PAGE>   16


         (a) First, to all Members, in proportion to the respective amounts of
Net Gain (if any) previously allocated to each such Member pursuant to Section
9.01(d) and not offset by prior allocations of Net Loss made pursuant to this
Section 9.02(a), an amount of Net Loss equal to the aggregate amount of such Net
Gain (if any);

         (b) Second, to the Class A Member, an amount of Net Loss equal to the
aggregate amount of Net Gain (if any) previously allocated to the Class A Member
pursuant to Section 9.01(c) and not previously offset by prior allocations if
Net Loss pursuant to this Section 9.02(b);

         (c) Third, to all Members, in proportion to the respective amounts of
Net Gain (if any) previously allocated to each such Member pursuant to Section
9.01(b) and not offset by prior allocations of Net Loss made pursuant to this
Section 9.02(c), an amount of Net Loss equal to the aggregate amount of such Net
Gain (if any); and

         (d) Fourth, to all Members in proportion to their respective
Contributions.

         SECTION 9.03.  OTHER SPECIALLY ALLOCATED ITEMS.

         (a) As of the end of each fiscal year of the Company and after giving
effect to the special allocations set forth in Section 9.04 and APPENDIX B, the
Return Interest of the Company for such fiscal year shall be allocated to the
Managing Member.

         (b) From time to time, in its sole discretion, the Advisory Committee
may set off against the Excess Costs the unallocated pool amounts described in
Sections 4 and 5 of the GCC Investments, Inc. Incentive Pool Plan as adopted
effective November 1, 1996, as amended from time to time, and the Advisory
Committee in its sole discretion may make such adjustments to the allocations
made or to be made under this Article IX as it may determine to be necessary or
appropriate.

         SECTION 9.04.  LIMITATION ON LOSS ALLOCATIONS.

         (a) If and to the extent that any allocation of Company items in the
nature of loss or expense to any Member would cause such Member's Capital
Account to be negative, then such item(s) shall be allocated first to the
Capital Accounts of the other Members in proportion to the positive balances in
their respective Capital Accounts until all such Capital Accounts are reduced to
zero, and then to the Capital Accounts of the Members in such proportions as the
Advisory Committee may determine. An allocation pursuant to this Section 9.04
shall be made only if and to the extent that such Member's Capital Account would
be negative after all allocations required by this Article IX have been made
tentatively as if this Section 9.04 and APPENDIX B were not included in this
Agreement.

         (b) In the event that any special allocations of losses or expenses are
made pursuant to Section 9.04(a), items of gross Company income and gain from
subsequent periods shall be specially allocated to offset, to the extent
feasible and as promptly as possible, such special allocations of loss or
expense.

                                      -12-

<PAGE>   17


         SECTION 9.05.  TIMING OF ALLOCATIONS.

         (a) The Advisory Committee shall cause the allocations required by this
Agreement to be made no less frequently than as of the end of each fiscal year.

         (b) With respect to gains and losses on distributions in kind, (i) any
Net Gain or Loss deemed to have been realized pursuant to Section 8.02 on a
distribution of property in kind shall be allocated, immediately prior to the
time such distribution is made, to and among the Members' Capital Accounts on
the same basis as an equivalent amount of Net Gain or Loss would be allocated
for a hypothetical fiscal year ending immediately prior to such distribution;
and (ii) for this purpose, there shall be taken into account any Net Gain or
Loss attributable to distributions in kind previously made during the fiscal
year but, for administrative convenience, there shall not be taken into account
other items of Company income, gain, loss or deduction realized or incurred
since the end of the prior fiscal year, except as provided in Section 9.05(c).

         (c) The Advisory Committee may cause the Company to make the
allocations described in this Article IX (other than allocations for tax
purposes pursuant to Part 4 of APPENDIX B) at a time other than as of the end of
a fiscal year on the basis of an interim closing of the Company's books at such
time. In that event, each short fiscal period attributable to any such interim
closing shall constitute a fiscal year for purposes of this Article IX. In the
event that the Company sells, transfers or otherwise exchanges a Portfolio
Security during a fiscal quarter, and such sale, transfer or exchange would
cause such Portfolio Security to be treated as a Disposed Investment for
purposes of this Agreement, then the Managing Member shall make the allocations
described in Article IX (other than allocations for tax purposes pursuant to
Part 4 of APPENDIX B) as of the end of such fiscal quarter on the basis of an
interim closing of the Company's books at such time.

         SECTION 9.06. ADVISORY NATURE OF ALLOCATIONS. The allocation provisions
contained in this Article IX and in APPENDIX B are advisory allocations only,
and shall have no effect on the amounts to be distributed to the Members
pursuant to the Agreement, whether in liquidation or otherwise. Accordingly, if
the Advisory Committee determines that in any fiscal year the allocations set
forth in this Article IX and in APPENDIX B do not satisfy the "economic effect
equivalence" test or the "partners' interest in the partnership" test and would
not otherwise be respected under the provisions of Section 704(b) of the Code,
then all items of Net Gain, Net Loss and other items of income, gain, loss,
deduction and credit shall be allocated to and among the Members so as to ensure
to the maximum extent possible (i) that such allocations satisfy the economic
effect equivalence test of Treasury Regulations Section 1.704-1(b)(2)(ii)(i) or
the partners interest in the partnership test of Treasury Regulations Section
1.704-(b)(3) and (ii) that all allocations of items that cannot have economic
effect are allocated to the Members in accordance with their interests in the
Company. Without limiting the foregoing, the economic effect equivalence test
may generally be satisfied by allocating items that can have economic effect so
that the balance of each Member's Capital Account at the end of any taxable year
would be equal to the amount of cash that the Member would receive (or would be
negative by the amount of cash that such Member would be required to contribute
to the Company) if the Company sold all of its property for an amount of cash
equal to the book value (as determined pursuant to Treasury Regulations Section
1.704-1(b)(2)(iv)) of such property, and all of the cash

                                      -13-

<PAGE>   18


of the Company remaining after payment of all liabilities of the Company were
distributed in liquidation immediately following the end of such taxable year
pursuant to the Agreement. In the event that the Company incurs any liability,
claim or indebtedness that would constitute a "nonrecourse liability" within the
meaning of Section 704(b) of the Code and the Treasury Regulations promulgated
thereunder, the Advisory Committee may make such adjustments to the foregoing
allocation provisions as it may determine to be necessary or appropriate.


                                    ARTICLE X

                                  DISTRIBUTIONS

         SECTION 10.01.  AMOUNT, TIMING AND FORM.

         (a) The Advisory Committee, after soliciting the recommendation of the
Managing Member, shall determine the amount, timing and form (including whether
such distribution shall be made in cash or in securities) of all distributions
made by the Company and the decision of the Advisory Committee shall be binding
upon the Members. Notwithstanding the foregoing, the Advisory Committee shall
cause the Company to distribute the net proceeds from the disposition of
Portfolio Securities within ten (10) days after the end of the fiscal quarter in
which such disposition occurs.

         (b) Unless otherwise determined by the Advisory Committee, each class
of securities to be distributed in kind shall be distributed to the Members in
proportion to their respective shares of the proposed distribution as provided
in Section 10.02, except to the extent that a disproportionate distribution of
such 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 shall be treated as
a separate class of securities.

         (c) Notwithstanding anything to the contrary set forth herein, in the
event that the distribution of securities to any Member would result in the
recognition of gain by any Member under federal, state or local income tax laws,
the Advisory Committee, in its sole discretion, shall have the authority to make
such adjustments to the amounts distributable to the Members under this Article
X as it may deem to be necessary or appropriate, including but not limited to
causing the Company to refrain from making any distribution of securities to any
Member.

         SECTION 10.02.  DISTRIBUTIONS.

         (a) Except as otherwise explicitly provided in this Agreement, all
distributions prior to the commencement of the liquidation of the Company's
assets pursuant to Article XII shall be made in accordance with this Section
10.02. All distributions made pursuant to, or referred to in, this Section 10.02
are referred to herein as "DISTRIBUTIONS."

                                      -14-

<PAGE>   19


         (b) First, Distributions shall be made to all Members in proportion to
their respective Priority Return Amounts until each Member has received
aggregate Distributions pursuant to this Section 10.02(b) equal to such Member's
Priority Return Amount;

         (c) Second, Distributions shall be made to and among the Members until
each Member has received aggregate Distributions pursuant to this Section
10.02(c) and the proviso in the first sentence of Section 10.03(f) equal to such
Member's Distribution Preference;

         (d) Third, Distributions shall be made to the Class A Member until the
Class A Member has received aggregate Distributions pursuant to this Section
10.02(d) and Section 10.03(f)(i) equal to the Class A Member's Make-Whole
Amount; and

         (e) Thereafter, Distributions shall be made 80% to all Members in
proportion to their respective Contributions and 20% to the Managing Member.

         (f) For purposes of Sections 10.02(b), (c), (d) and (e) hereof:

                  (i) If at any time the Managing Member is entitled to a larger
         distribution than it would otherwise be entitled in order to achieve
         the result required by clause (2) of the proviso in Section 14.2(c) of
         the GPLLC Agreement, then the distribution to the Class A Member shall
         be reduced proportionately and the aggregate amount of such reductions
         from time to time is referred to herein as the "Distribution
         Deficiency."

                  (ii) All Distributions made to any Member's predecessors in
         interest shall be treated as having been made to such Member;

                  (iii) In calculating the amount of any Distribution to be made
         pursuant to Section 10.02(b), (c), (d) or (e), amounts to be
         distributed contemporaneously pursuant to an earlier clause (e.g.,
         Section 10.02(b)) shall be taken into account in determining the
         amounts distributable with respect to each later clause (e.g., Section
         10.02(c)) as if such amounts had actually been distributed pursuant to
         the earlier clause before the amounts distributable pursuant to the
         later clause are determined;

                  (iv) As of the date that any Distribution is to be made "20%
         to the Managing Member" pursuant to Section 10.02(e), the "Applicable
         Percentage" of the aggregate amount of such Distribution shall be
         retained by the Company and later distributed to the Managing Member
         pursuant to the terms of Section 10.03(a) hereof (the aggregate amounts
         so retained are referred to herein as the "UNALLOCATED AMOUNT");

                  (v) As of the date that any Distribution is to be made "20% to
         the Managing Member" pursuant to Section 10.02(e), seventy percent of
         the aggregate amount of such Distribution that is not part of the
         Unallocated Amount (the "CASH COMPONENT") shall be retained by the
         Company and distributed to the Managing Member pursuant to the terms of
         Section 10.03(b) hereof; and

                  (vi) As of the date that any Distribution is to be made "20%
         to the Managing Member" pursuant to Section 10.02(e), thirty percent of
         the aggregate amount of such

                                      -15-

<PAGE>   20


         Distribution that is not part of the Unallocated Amount (the "STOCK
         COMPONENT") shall be retained by the Company and distributed to the
         Managing Member pursuant to the terms of Section 10.03(c) hereof.

         SECTION 10.03. DISTRIBUTION LIMITATIONS. Notwithstanding anything to
the contrary contained in Section 10.02(e) or in any other provision of this
Agreement, as of the date that any Distribution is to be made "20% to the
Managing Member" pursuant to Section 10.02(e) (the "DISTRIBUTION DATE"), the
Company shall retain to the extent required by Section 10.02(f)(iv), (v) and
(vi), a portion of such Distribution and shall distribute the amount retained in
the manner set forth in this Section 10.03.

         (a) From time to time, the Advisory Committee may apply against the
Unallocated Amount (i) any Distribution Deficiency to the extent not previously
applied against the Unallocated Amount, plus (ii) 20% of the sum of the
following: (A) Excess Management Fee Payments; plus (B) the portion of the
Members' Contributions that is reflected in the Company's books as having been
used by the Company to acquire Portfolio Securities that are Disposed
Investments and which were disposed of by the Company for a value which was less
than the Cost of such Portfolio Securities, but only to the extent that the
amounts in clauses (A) and (B) have not been applied previously against the
Unallocated Amount, recovered pursuant to Distributions under Sections 10.02(b)
and (d), or set off by the Advisory Committee pursuant to Section 9.03(b) (the
foregoing amounts in clauses (i) and (ii) being referred to as the "Excess
Cost"). The amount so applied shall reduce the Unallocated Amount as follows:
First, against any amount credited to the Unallocated Amount pursuant to Section
10.03(f) plus interest accrued thereon; and Second, against the remainder of the
Unallocated Amount plus interest accrued thereon on a first-in, first-out basis,
and the amount applied against the remainder of the Unallocated Amount shall be
distributed to the Class A Member. Any funds plus interest accrued thereon
retained by the Company in the Unallocated Amount for more than five years,
other than funds credited to the Unallocated Amount pursuant to Section
10.03(f), shall be released from the Unallocated Amount and distributed to the
Managing Member within thirty days after the end of the fiscal quarter in which
such anniversary date occurs. Interest shall accrue on the Unallocated Amount at
the Class A Member's investment rate, as designated from time to time by the
Class A Member, and shall constitute Return Interest.

         (b) The Cash Component of any Distribution shall be distributed to the
Managing Member in three annual installments beginning on the Distribution Date.
The first installment distributable to the Managing Member shall constitute 45%
of the total amount of the Cash Component. The second and third installments of
the Cash Component shall each constitute 27.5% of the total amount of the Cash
Component. The second and third annual installment of the Cash Component shall
include interest on the amount of such installment calculated at the Prime Rate
per annum from the Distribution Date, which interest shall constitute Return
Interest. Notwithstanding the foregoing, the Advisory Committee may reduce (but
not below 33.3%) or increase the amount of the first installments distributable
to the Managing Member if the Advisory Committee determines, after consulting
with the Company's tax advisors, that the federal, state and local income tax
liability of the members of the Managing Member on account of Net Gain allocated
to the Managing Member pursuant to Article IX with respect to such Distribution
(i) may be offset by previously allocated Net Loss which is carried forward from

                                      -16-

<PAGE>   21


prior fiscal years or (ii) may be greater or lesser due to changes in federal,
state or local tax rates. One-half of the amount of any such reduction or
increase shall be reflected in the second installment of the Cash Component and
the other one-half shall be reflected in the third installment of the Cash
Component.

         (c) The Stock Component of any Distribution shall be distributed to the
Managing Member in five equal annual installments beginning on the Distribution
Date. Upon the distribution of each such installment, GCX shall have the right
to require the Managing Member to use the entire amount of such installment to
purchase on that date common stock of GCX, as provided in the Put Agreement
attached as SCHEDULE B.

         (d) Any amounts retained by the Company pursuant to Section 10.03(a),
(b) and (c) which have not been distributed after the liquidation of the Company
pursuant to this Agreement shall be immediately released to the Managing Member;
provided, however, that the Managing Member has not been required to withdraw as
the Managing Member for Cause pursuant to Article XIV.

         (e) At the election of the Class A Member, the Company shall make
available an advance to a designated Affiliate of the Class A Member that
portion of the Unallocated Amount, the Cash Component and the Stock Component
not distributed to the Managing Member as the Class A Member may specify. Any
such advance shall be repaid to the Company, with interest (i) on the Cash
Component calculated at the Prime Rate per annum, and (ii) on any Unallocated
Amount, calculated at the Class A Member's investment rate, as designated from
time to time by the Class A Member, and the amount of such interest shall be
applied against and reduce interest accruing pursuant to Section 10.03(a) and
(b). No interest shall be payable by the designated Affiliate of the Class A
Member on the portion of an advance that corresponds to the Stock Component of
any Distribution.

         (f) If the interest of a member of the Managing Member is converted
into a "retired member" interest under the GPLLC Agreement resulting in the
forfeiture of certain distributions to which such member would otherwise have
been entitled under the provisions of the GPLLC Agreement but for the provisions
of Section 10.02(f)(iv), (v) and (vi) hereof, then the amount of such forfeited
distributions shall be distributed as follows: (i) First, to the Class A Member
in the event that, at such time, the Class A Member has not received
distributions pursuant to Section 10.02(d) hereof equal to its Make-Whole
Amount, in an amount equal to such shortfall; and (ii) Second, the remainder
shall be distributed to the Class A Member, and any amount so distributed
pursuant to this clause Second shall be credited to the Unallocated Amount;
provided, however, that if the interest of a member of the Managing Member is
converted into a "retired member" interest pursuant to Section 14.2(c)(i) of the
GPLLC Agreement due to the voluntary retirement of such member after the date
which is five years but prior to the date which is twelve years after such
member's admission as a member of the Managing Member, then the amount of such
forfeited distributions shall be distributed to all Members pursuant to Section
10.02(c) and in accordance with the provisions of Section 10.01 until each
Member has received aggregate Distributions pursuant to Section 10.02(c) and
this proviso equal such Member's Distribution Preference and, thereafter, to all
Members in proportion to their respective Contributions, and the amount
distributed to each Member in proportion to its Contribution shall be credited
to, and

                                      -17-

<PAGE>   22


shall reduce the amount of, such Member's Distribution Preference which accrues
from time to time thereafter. Notwithstanding the foregoing, upon the
recommendation of the Managing Member, the Advisory Committee may determine to
distribute any such forfeited distributions to the Managing Member. The Managing
Member, at the direction of the Advisory Committee, shall make such adjustments
to the allocation of Net Gain, Net Loss and gross items of income, gain, loss,
deduction and credit as the Advisory Committee may determine to be necessary to
reflect the economic agreement of the Members set forth in this Section
10.03(f).

         (g) If a Distribution relates to a Portfolio Company which had an
initial public offering of its securities after the Company's initial investment
in such Portfolio Company, then the date of each installment under Sections
10.03(b) and 10.03(c) with respect to such Distribution, other than the initial
installment of such Distribution, shall be an anniversary date of such initial
public offering commencing with the anniversary date following the date on which
the securities of such Portfolio Company are disposed of or distributed in kind
by the Company.

         SECTION 10.04.  TAX WITHHOLDING.

         (a) If the Company incurs any obligation to pay any amount in respect
of taxes (including withholding taxes and any interest, penalties or additions
to tax) imposed on income of or distributions made to any Member or former
Member, any amount so required to be paid by the Company with respect to such
Person shall be treated for all purposes of this Agreement as if it had been
loaned to such Person, and the Managing Member shall cause the Company to give
prompt written notice to such Person of the date and amount of such loan.

         (b) Each Member covenants, for itself, its successors, assigns, heirs
and personal representatives, that such Person shall pay to the Company at any
time after notice of the loan has been given, but not later than thirty (30)
days after the Company delivers a written demand to such Person for such
repayment (which demand may be made at any time prior to or after the
dissolution of the Company or the Managing Member or the withdrawal of such
Person or its predecessors from the Company); provided, however, that if any
such repayment is not made within such thirty (30) day period:

                  (i) Such Person shall pay interest to the Company at the
         Short-Term T-Bill Rate for the entire period commencing on the date on
         which the Company paid such amount and ending on the date on which such
         Person repays such amount to the Company together with all accrued but
         previously unpaid interest; and

                  (ii) The Company, at the discretion of the Managing Member,
         shall (1) collect such unpaid amounts (including interest) from any
         Company distributions that otherwise would be made to such Person
         and/or (2) subtract from the Capital Account of such Person, no later
         than the day prior to the Company's initial liquidating distribution,
         any such unpaid amounts (plus unpaid interest) not so collected, in
         each case treating the amount so collected or subtracted as having been
         distributed to such Person at the time of such collection or
         subtraction.

<PAGE>   23


                  (iii) For purposes of this Agreement, any interest paid by a
         Member to the Company pursuant to Section 10.04(b)(i) shall not be
         included in "NET GAIN OR LOSS" as defined hereunder, and shall instead
         be allocated to and among the other Members in proportion to their
         respective Contributions. No such interest shall increase the Capital
         Account or the Contributions of the paying Member for any purpose.

         (c) For purposes of this Section 10.04, any tax withholding obligation
incurred by the Managing Member with respect to any Member shall constitute a
Company obligation.

         SECTION 10.05. CERTAIN DISTRIBUTIONS PROHIBITED. Anything in this
Article X to the contrary notwithstanding, no distribution shall be made to any
Member if, and to the extent that such distribution would not be permitted under
Section 18-607(a) of the Delaware Act.

         SECTION 11.02.  DISSOLUTION.  The Company shall be dissolved:

         (a) in the event of the bankruptcy, dissolution or withdrawal of the
Managing Member, unless the Class A Member agrees to continue the Company and
elect a replacement for the Managing Member within ninety (90) days after such
event; or

         (b) upon the written notice of the Class A Member.


                                   ARTICLE XII

                           LIQUIDATION OF THE COMPANY

         SECTION 12.01. GENERAL PROVISIONS. At dissolution, the Company's assets
shall be liquidated in an orderly manner. The Managing Member shall be the
liquidator to wind up the affairs of the Company pursuant to this Agreement;
provided that the Class A Member may designate one or more other Persons to act
as the liquidator(s) instead of the Managing Member. Any such liquidator(s),
other than the Managing Member, shall be a "liquidating trustee" within the
meaning of Section 18-101(9) of the Delaware Act.

         SECTION 12.02. LIQUIDATING DISTRIBUTIONS. The liquidator(s) shall pay

creditors. Any Net Gain or Loss, and other items in the nature of income, gain,
loss, deduction and credit realized in connection with the liquidation of the
Company shall be allocated among the Members pursuant to

                                      -19-

Article IX, and the remaining assets of the Company shall then be distributed to
the Members in cash (to the extent feasible) or in kind in the manner described
in Article X, subject to any adjustments to the amounts distributable to the
Managing Member pursuant to Article XIV. In performing their duties, the
liquidator(s) shall be authorized to sell, exchange or otherwise dispose of the
assets of the Company in such reasonable manner as the liquidator(s) shall
determine to be in the best interest of the Members. During the liquidation of
the Company, the liquidator(s) shall furnish to the Members the financial
statements and other information specified in Article XVII.

         SECTION 12.03. EXPENSES OF LIQUIDATOR(S). The expenses incurred by the
liquidator(s) in connection with winding up the Company, all other losses or
liabilities of the Company incurred in accordance with the terms of this
Agreement, and reasonable compensation for the services of the liquidator(s)
(which, with respect to any liquidator who is a Managing Member, shall be paid
only if the Managing Member is not also receiving the management fee pursuant to
the terms of the Management Agreement) shall be borne by the Company.

         SECTION 12.04. DURATION OF LIQUIDATION. A reasonable time shall be
allowed for the winding up of the affairs of the Company in order to minimize
any losses otherwise attendant upon such a winding up. The liquidator(s) shall
use its best efforts to dispose of or distribute all Company assets within one
year of dissolution, but shall not be bound to do so or liable in any way to any
Member for failure to do so. The liquidator(s) shall then make final liquidating
distributions from the Company on or before the later of (a) the end of the
taxable year in which the date of liquidation of the Company occurs, or (b)
ninety (90) days after the date of the liquidation of the Company. For this
purpose, (1) the date of the liquidation of the Company shall be the date on
which the Company has ceased to be a going concern, and (2) the Company shall
not be deemed to have ceased to be a going concern until it has sold,
distributed or otherwise disposed of its Portfolio Securities.

         SECTION 12.05. DUTY OF CARE. The liquidator(s) shall not be liable to
the Company or any Member for any loss attributable to any act or omission of
the liquidator(s) taken in good faith in connection with the liquidation of the
Company and distribution of its assets in the belief that such course of conduct
was in the best interest of the Company. The liquidator(s) may consult with
counsel and accountants with respect to liquidating the Company and distributing
its assets and shall be justified in acting or omitting to act in accordance
with the advice or opinion of such counsel or accountants, provided they shall
have been selected with reasonable care.

         SECTION 12.06. NO LIABILITY FOR RETURN OF CAPITAL. The liquidator(s),
the Managing Member and their respective officers, directors, agents, partners,
members and Affiliates shall not be personally liable for the return of the
capital contributions of any Member to the Company. Neither the Managing Member
nor the Class A Member shall be obligated to restore to the Company any amount
with respect to a negative Capital Account; PROVIDED, HOWEVER, that the
foregoing shall not affect the obligation of any Member to make such Member's
agreed upon capital contributions to the Company.

Treasury Regulations.

         SECTION 13.03. OTHER PROHIBITED LEGAL CONSEQUENCES. No Transfer shall

extent of the membership interest transferred.

         SECTION 13.05. COVENANTS OF CLASS A MEMBER. The Class A Member agrees
that it will not make any Transfer of all or any part of its membership interest

loss, deduction and credit in its discretion as it determines to be necessary to
reflect the economic agreement among the Members concerning the consequences of
such removal;

                  (ii) the holder of a Retired Member interest shall continue to
be treated as a Member for purposes of this Agreement, but shall take no part in
the management, policy or control of the Company and shall have no power or

interest as described in clause (iv)(A) above, resulting in the forfeiture of
certain distributions to which such member would otherwise have been entitled

         SECTION 16.01. GENERAL PROVISIONS. The Managing Member, its members
(including but not limited to each Principal), officers, employees and agents,
each member of the Advisory Committee, and the Class A Member (each such Person
being referred to herein as an "INDEMNITEE") shall be indemnified by the Company
(only out of Company assets, including the proceeds of liability insurance)
against any claim, demand, controversy, dispute, cost, loss, damage, expense
(including attorneys' fees), judgment and/or liability incurred by or imposed
upon the Indemnitee in connection with any action, suit or proceeding (including
any proceeding before any administrative or legislative body or agency) to which
the Indemnitee may be a party or otherwise involved, or with which the
Indemnitee may be threatened, by reason of the Indemnitee's being at the time
the cause of action arose or thereafter, the Managing Member, a member,
director, officer, employee, consultant or other agent of the Managing Member, a
member of the Advisory Committee, or the Class A Member, or an Affiliate of any
of the foregoing, or a director, officer, partner, employee, consultant or other
agent of any other organization in which the Company owns or has owned an
interest or of which the Company is or has been a creditor, which other
organization the Indemnitee serves or has served as director, officer, partner,
employee, consultant or other agent at the request of the Company (whether or
not the Indemnitee continues to serve in such capacity at the time such action,
suit or proceeding is brought or threatened), except with respect to matters
which result in the Indemnitee being enjoined from future violations of federal
or state securities laws or as to which the Indemnitee shall have been finally
adjudicated in any such action, suit or proceeding (a) not to have acted in good
faith or to have acted with gross negligence or a willful disregard of his
duties, or in breach of his fiduciary obligations, or (b) with respect to any
criminal action or proceeding, not to have had reasonable cause to believe that
the Indemnitee's conduct was lawful. In the event of a settlement in connection
with any action, suit or proceeding, such indemnification shall apply to all
matters covered by the settlement except for matters as to which the Company is
advised by independent counsel (chosen by the Managing Member and approved by
the Advisory

                                      -24-

<PAGE>   29


Committee), that in the opinion of such counsel the person seeking
indemnification did not act in good faith or acted with gross negligence or
willful disregard of his duties. Each Indemnitee shall be entitled to
indemnification pursuant to this Article XVI notwithstanding that the Company
has sold, assigned, distributed or otherwise transferred its entire interest in
such other organization prior to the time that such action, suit or proceeding
is brought or threatened. The foregoing right of indemnification shall be in
addition to any rights to which any Indemnitee may otherwise be entitled. The
foregoing right of indemnification shall inure to the benefit of the executors,
administrators, personal representatives, successors or assigns of each such
Indemnitee.

         SECTION 16.02. ADVANCE PAYMENT OF EXPENSES. The Company shall pay the
expenses incurred by an Indemnitee in defending a civil or criminal action, suit
or proceeding, or in opposing any claim arising in connection with any potential
or threatened civil or criminal action, suit or proceeding, in advance of the
final disposition of such action, suit or proceeding, upon receipt of an
enforceable undertaking by such Indemnitee to repay such payment if he shall be
determined to be not entitled to indemnification therefor as provided herein;
PROVIDED, HOWEVER, that in such instance the Indemnitee is not defending an
action, suit or proceeding commenced against him by the Company or opposing a
claim by the Company arising in connection with any such potential or threatened
action, suit or proceeding.

         SECTION 16.03. LIMITATION BY LAW. If the Managing Member or the Company
is subject to any federal or state law, rule or regulation which restricts the
extent to which any person may be exonerated or indemnified by the Company, then
the indemnification provisions set forth in this Article XVI and the exoneration
provisions set forth in Sections 3.07, 6.06 and 12.05 shall be deemed to be
amended, automatically and without further action by the Managing Member or the
Class A Member, to conform to such restrictions on exoneration or
indemnification as set forth in such applicable federal or state law, rule or
regulation. The rights to indemnification and advancement of expenses conferred
in this Article XVI shall not be exclusive of any other right which any
Indemnitee may have or hereafter acquire under any law, statute, rule,
regulation, charter document, by-law, contract or agreement.

Member in order to obtain any available exemption from, or any available refund
of, any withholding or similar taxes imposed by any taxing authority with
respect to amounts distributable to the Members or items of income allocable to

         SECTION 19.01. NOTICES. Except where otherwise specifically provided in
this Agreement, all notices, requests, consents, approvals and statements shall
be in writing and shall be deemed to have been properly given by personal
delivery or if mailed from within the country of the sender by air mail, postage
prepaid, or if sent by prepaid telegram, electronic facsimile transmission or
telex, or if sent by courier service, addressed in each case, if to the Company
or to any Member, at its address set forth in SCHEDULE A, or, in each case, to
such other address or addresses as the addressee may have specified by written
notice as aforesaid to the other parties.

         SECTION 19.02. ADDITIONAL DOCUMENTS. Each Member hereby agrees to
execute all certificates, counterparts, amendments, instruments or documents
that may be required by the laws of the various jurisdictions in which the
Company conducts its activities, to conform with the laws of such jurisdictions
governing limited liability companies.

         SECTION 19.03. BINDING ON SUCCESSORS. This Agreement shall be binding
upon and it shall inure to the benefit of the respective heirs, successors,
assigns and legal representatives of the parties hereto.

         SECTION 19.04. COUNTERPARTS. This Agreement or any amendment hereto may

construed in accordance with the laws of the State of Delaware.

         SECTION 19.06. SECURITIES ACT MATTERS. Each Member understands that in
addition to the restrictions on transfer contained in this Agreement, it must
bear the economic risks of its investment for an indefinite period because the
Company interests have not been registered under the Securities Act and,
therefore, may not be sold or otherwise transferred unless they are registered
under the Securities Act or an exemption from such registration is available.
Each Member agrees with all other Members that it will not sell or otherwise
transfer its interest in the Company unless such interest has been so registered
or in the opinion of counsel for the Company, or of other counsel reasonably
satisfactory to the Company, such an exemption is available.

         SECTION 19.07. RIGHT TO RELY ON AUTHORITY OF MANAGING MEMBER. No Person
that is not a Member, in dealing with the Managing Member, shall be required to
determine such Managing Member's authority to make any commitment or engage in
any undertaking on behalf of the Company, or to determine any fact or
circumstance bearing upon the existence of the authority of the Managing Member.

         SECTION 19.08. TAX MATTERS PARTNER. The "tax matters partner," as
defined in Section 6231 of the Code, of the Company shall be the Class A Member
(the "TAX MATTERS

                                      -27-

<PAGE>   32


PARTNER"). The Tax Matters Partner shall not resign as tax matters partner of
the Company unless, on the effective date of such resignation, the Company has
designated another Member as Tax Matters Partner and that Member has given its
consent in writing to its appointment as Tax Matters Partner. The Tax Matters
Partner shall receive no additional compensation from the Company for its
services in that capacity, but all reasonable expenses incurred by the Tax
Matters Partner in its capacity as such shall be borne by the Company. The Tax
Matters Partner is authorized to employ such accountants, attorneys and agents
as it, in its sole discretion, determines are necessary to or useful in the
performance of its duties. If the Class A Member is not eligible to serve as the
Tax Matters Partner under applicable law, then the Managing Member shall be the
Tax Matters Partner, but in that event the Managing Member shall consult with
the Class A Member, and shall obtain the Class A Member's advance consent, in
connection with any action the Managing Member proposes to take as Tax Matters
Partner. Any Person who serves as Tax Matters Partner shall not be liable to the
Company or to any Member for any action it takes or fails to take as Tax Matters
Partner with respect to any administrative or judicial proceeding involving
"Partnership items" (as defined in Section 6231 of the Code) of the Company,
unless such action or failure to act constitutes a violation of the duty of care
standards set forth in Section 3.07.

         SECTION 19.09. CONTRACT CONSTRUCTION. Whenever the content of this
Agreement permits, the masculine gender shall include the feminine and neuter
genders, and reference to singular or plural shall be interchangeable with the

provisions as they may be amended after the date of this Agreement.

         SECTION 19.10. SECTION HEADINGS. Captions in this Agreement are for
convenience only and do not define or limit any term of this Agreement.

original or any such follow-on investment in

records maintained in accordance with federal income tax principles) represented
by the portion of such security that was repurchased, lapsed or terminated; and

                         REGULATORY AND TAX ALLOCATIONS

1.       REGULATORY ALLOCATIONS.
The following provisions are included in order to comply with tax rules set
forth in the Code and in the Treasury Regulations.

1.1      QUALIFIED INCOME OFFSET.
If any Member unexpectedly receives an adjustment, allocation or distribution
described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6),
and such adjustment, allocation or distribution causes such Member to have a
deficit balance in such Member's Capital Account or further reduces a balance in
such Member's Capital Account that already has a deficit balance, there shall be
allocated to such Member items of income and gain (consisting of a pro rata
portion of each item of Company income, including gross income, and gain for
such fiscal period) in an amount and manner sufficient to eliminate such
Member's deficit Capital Account balance, to the extent required by Treasury
Regulations Section 1.704-1(b)(2)(ii)(d), as quickly as possible, provided that
an allocation pursuant to this 1.1 shall be made only if and to the extent that
there would be a deficit in such Member's Capital Account after all allocations
provided for in Article IX of the Agreement and in this APPENDIX B have been
made tentatively as if this 1.1 were not included in this Agreement. The
foregoing sentence is intended to constitute a "qualified income offset"
provision as described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d), and
shall be interpreted and applied in all respects in accordance with that
Section.

1.2      GROSS INCOME ALLOCATION.
In the event that any Member has a negative Capital Account at the end of any
Company fiscal year, there shall be allocated to such Member items of Company
income (including gross income) and gain in the amount of such excess as quickly
as possible, provided that an allocation pursuant to this 1.2 shall be made only
if and to the extent that there would be a deficit in such Member's Capital
Account after all allocations provided for in Article IX of the Agreement and in
this APPENDIX B have been made tentatively as if 1.1 and this 1.2 were not
included in this APPENDIX B.

1.3      ADJUSTMENTS TO REFLECT SECTION 754 ELECTION.
To the extent that an adjustment to the adjusted tax basis of any Company asset
pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to
Treasury Regulations Section 1.704-1(b)(2)(iv)(m), to be taken into account in
determining Capital Accounts, the amount of such adjustment to the Capital
Accounts shall be treated as an item of gain (if the adjustment increases the
basis of the asset) or loss (if the adjustment decreases such basis) and such
gain or loss shall be specially allocated to the Members in a manner consistent
with the manner in which their Capital Accounts are required to be adjusted
pursuant to such Section of the Treasury Regulations.

1.4      OFFSETTING ALLOCATIONS.
The allocations set forth in 1.1, 1.2 and 1.3 of this APPENDIX B (the
"REGULATORY ALLOCATIONS") are intended to comply with certain requirements of
Treasury Regulations Section 1.704-1(b).


<PAGE>   43


Notwithstanding any other provisions of Article IX of the Agreement and of this
APPENDIX B (other than the Regulatory Allocations), the Regulatory Allocations
shall be taken into account in allocating subsequent items of income, gain, loss
and expense among the Members so that, to the extent possible, the net amount of
such allocations of subsequent items of income, gain, loss and expense and the
Regulatory Allocations to each Member shall be equal to the net amount that
would have been allocated to each such Member pursuant to the provisions of
Article IX of the Agreement and this APPENDIX B if the Regulatory Allocations
had not occurred.

For purposes of applying the foregoing sentence, allocations pursuant to this
1.4 shall be made with respect to allocations pursuant to 1.3 of this APPENDIX B
only to the extent the Advisory Committee reasonably determines that such
allocations will otherwise be inconsistent with the economic agreement among the
Members. Further, if allocations to the Managing Member include or are affected
by Regulatory Allocations or allocations pursuant to this 1.4 that are intended
to offset such Regulatory Allocations, the Advisory Committee, after consulting
with the Company's accountants and other advisors, shall have discretion to make
such adjustments to subsequent allocations that the Advisory Committee deems
reasonably necessary or appropriate to effectuate the economic arrangements of
the Members.

2.       ADJUSTMENTS TO REFLECT CHANGES IN INTERESTS.
With respect to any fiscal period during which any Member's interest in the
Company changes, whether by reason of the admission of a Member, the withdrawal
of a Member, a non-pro rata contribution of capital to the Company or any other
event described in Section 706(d)(1) of the Code and the regulations issued
thereunder, allocations of Net Gain, Net Loss and other items of Company income,
gain, loss and expense shall be adjusted appropriately to take into account the
varying interests of the Members during such period. The Advisory Committee
shall consult with the Company's accountants and other advisors and shall select
the method of making such adjustments, which method shall be used consistently
thereafter.

3.       SPECIAL ALLOCATIONS OF GROSS GAINS AND LOSSES.
In making allocations of Net Gain or Net Loss pursuant to Article IX of the
Agreement, the Advisory Committee, after consulting with the Company's tax
advisors, is authorized to separate these aggregate amounts into their
components and to allocate the components separately in order to further the
intent of such provisions of the Agreement. For example, if with respect to a
particular fiscal period the Company realizes a gross loss of $100 on a sale of
Portfolio Securities and a gross gain of $200 on a sale of other securities
resulting in a Net Gain of $100 ($200 gross gain minus $100 gross loss = $100
Net Gain), the Advisory Committee may allocate the $100 gross loss as a $100 Net
Loss in the manner required by Section 9.02, and then allocate the $200 gross
gain as a $200 Net Gain in the manner required by Section 9.01, if advised by
the Company's tax advisors that such special allocations will cause the Capital
Accounts of the Members to reflect more closely the Members' relative economic
interests in the Company.

4.       TAX ALLOCATIONS.

4.1      GENERAL.
For federal, state and local income tax purposes, Company income, gain, loss,
deduction or credit (or any item thereof) for each fiscal year shall be
allocated to and among the Members in


<PAGE>   44


order to reflect the allocations made pursuant to the provisions of Article IX
of the Agreement and the provisions of this APPENDIX B for such fiscal year
(other than allocations of items which are not deductible or are excluded from
taxable income), taking into account any variation between the adjusted tax
basis and book value of Company property in accordance with the principles of
Section 704(c) of the Code.

4.2      SECTION 704(c) ALLOCATIONS; SECTION 704(c)(1)(B) AND SECTION 737 ITEMS.
In the event that the value of an item of property contributed to the Company
differs from its adjusted tax basis, allocations of depreciation, depletion,
amortization, gain, and loss with respect to such property will be made for
federal income tax purposes in a manner that takes account of the variation
between the adjusted tax basis and value of such property in accordance with
Section 704(c) of the Code using, as determined by the Advisory Committee,
either (i) the traditional method specified in Treasury Regulations Section
1.704-3(b), (ii) the traditional method with curative allocations specified in
Treasury Regulations Section 1.704-3(c), or (iii) the remedial allocation method
specified in Treasury Regulations Section 1.704-3(d).

If (i) any property is contributed to the Company by any Member, (ii) such
property is subsequently distributed to any Member, and (iii) pursuant to
Sections 704 (c)(1)(B) and 737 of the Code, any gain is required to be
recognized on such distribution by a contributing Member, the Advisory
Committee, in its sole discretion, may make such amendments to this Agreement as
it may deem necessary or appropriate, including but not limited to making a
special distribution from the Company to such contributing Member in an amount
determined by the Advisory Committee.

4.3      ALLOCATION OF NON-RECOURSE DEDUCTIONS.
Neither the Managing Member nor the Class A Member anticipate that the Company
will incur or realize any "nonrecourse deductions" (as defined in applicable
Treasury Regulations) or similar items but, if the Members anticipate at any
time that the Company may incur or realize any such items, the Managing Member
and the Class A Member may cause this Agreement to be amended to ensure to the
extent feasible that any such items are allocated in a manner that is both
consistent with the intent of the Members and likely to be respected for tax
purposes.

4.4      ISSUANCE ITEMS.
Notwithstanding any provision of this Agreement other than this APPENDIX B, any
income, gain, loss or deduction realized as a direct or indirect result of the
compensatory issuance of a Company interest by the Company to a Member (the
"ISSUANCE ITEMS") and, if necessary, all other items allocable to the Members
under this Agreement, shall be allocated among the Members so that, to the
extent possible, the net amount of such Issuance Items and other items allocated
to each Member shall be equal to the net amount that would have been allocated
to such Member if the Issuance Items had not been realized.
