                                        9


of the Company, except any indebtedness, liabilities and obligations to Members
on account of their Capital Contributions, have been paid or there remains
property of the Company sufficient to pay them. A Member, irrespective of the
nature of the Capital Contribution of such Member, has only the right to demand
and receive cash in return for such Capital Contribution.

                  6.8      No Rights of Redemption or Return of Contribution. 
Except in accordance with the provisions of this Agreement, no Member has a
right to have its Membership Interests or its Capital Contributions returned
prior to the dissolution of the Company.

                                   ARTICLE VII
                          Allocations and Distributions

                  7.1      Allocation of Profits and Losses.

                           (a) Profits for each Accounting Period shall be
                  allocated among the Members as follows:

                                    (1) First, to the Members with deficit 
Capital Account balances at the end of such Accounting Period (but prior to any
allocation of Profits pursuant to this Section 7.1(a)), in proportion to such
deficits, until such deficits are reduced to zero;

                                    (2) Second, to the Members if Members' 
Capital Accounts do not correspond to their Percentage Interests at the end of
such Accounting Period (after the allocation of Profits provided for in Section
7.1(a)(1), but prior to any other allocations of Profits pursuant to this
Section 7.1(a)) so as to make Members' Capital Accounts correspond to their
Percentage Interests; and

                                    (3) The balance, to the Members in 
proportion to their Percentage Interests.

                           (b) Losses for each Accounting Period shall be
allocated as follows:

                                    (1) First, to the Members if Members' 
Capital Accounts do not correspond to their Percentage Interests at the end of
such Accounting Period, so as to make Members' Capital Accounts correspond to
their Percentage Interests; and

                                    (2) The balance, to the Members in 
proportion to the Percentage Interests.

                  7.2      Distributions. All Distributions other than 
Distributions pursuant to Section 7.4 hereof shall be made to the Members in
proportion to the amounts by which their Capital Contributions exceed all
Distributions previously made to such Members until each has received amounts in
the aggregate equal to its Capital Contribution, and then in proportion to their
Percentage Interests.

                                       10


                  7.3      No Right to Distributions Except
                           Upon Dissolution of the Company.

                  The occurrence of a Dissolution Event with respect to the
Company shall entitle each Member to receive the Distributions set forth in
Section 7.4. In the absence of a Dissolution Event, no Member shall have any
right to receive Distributions.

                  7.4      Distributions Upon Dissolution of the Company. Upon
dissolution of the Company, the Company shall satisfy (or provide for the
satisfaction of) all the Company's debts and other obligations (including any
debts to Members and former Members). Thereafter, all Distributions shall be
made to the Members in proportion to the positive balances of such Members'
Capital Accounts (after such Capital Accounts have been adjusted to take into
account all events related to such dissolution).

                  7.5      Offset. The Company may offset all amounts owing to 
the Company by a Member against any Distribution to be made to such Member.

                  7.6      Limitation Upon Distributions. No Distribution shall 
be declared and paid unless, after such Distribution is made, the assets of the
Company are in excess of all liabilities of the Company.

                  7.7      Interest on and Return of Capital Contributions. No 
Member shall be entitled to interest on its Capital Contribution or to a return
of its Capital Contribution, except as specifically set forth in this Agreement.

                                  ARTICLE VIII
                                   Tax Matters

                  8.1      Tax Characterization and Returns.

                           (a) The Members acknowledge that for federal, state 
and local tax purposes the Company will be disregarded as an entity separate
from its Member at all times at which it has only one Member and treated as a
"partnership" at all other times. All provisions of this Agreement and the
Certificate of Formation are to be construed so as to preserve that tax status.
Without limiting the foregoing, to the extent the Tax Matters Partner determines
that provisions of this Agreement are inconsistent with the Company's tax status
at any time at which the Company has only one Member, those provisions shall not
apply at such time.

                           (b) To the extent applicable, within ninety (90) days
after the end of each Fiscal Year, the Tax Matters Partner will cause to be
delivered to each Person who was a Member at any time during such Fiscal Year a
Form K-1 and such other information, if any, with respect to the Company as may
be necessary for the preparation of each Member's federal, state or local income
tax (or information) returns, including a statement showing each Member's share
of income, gain or loss, and credits for the Fiscal Year.

                                       11


                  8.2      Capital Accounts.

                           (a) The Capital Account of each Member shall be 
increased by

                               (1)  the amount of all Capital Contributions 
made by such Member (which amount, in the case of contributed property other
than cash, shall be the Net Agreed Value thereof) and

                                (2)  all Profit and each item of income and gain
which is allocated to the Member pursuant to Section 7.1, 8.3(b), and 8.3(c)
hereof (computed in each instance with the adjustments detailed in Section
8.2(b) below) 

and decreased by

                                (x)  all Loss and each item of loss and 
deduction which is allocated to the Member pursuant to Section 7.1, 8.3(b), and
8.3(c) (computed in each instance with the adjustments detailed in Section
8.2(b) below) and

                                (y)  all cash and the Net Agreed Value of any 
property distributed by the Company to such Member pursuant to this Agreement.

                           (b)  Solely for the purposes of maintaining the 
Members' Capital Accounts, the Profit or Loss of the Company and each item of
income, gain, loss, or deduction which is specially allocated pursuant to
Section 8.3(b) and 8.3(c) shall be adjusted as follows:

                                (1)  Any income of the Company that is exempt 
from federal income tax shall be added to such Profit or Loss;

                                (2)  all deductions for depreciation, cost 
recovery, amortization, or similar items attributable to any property (other
than cash) contributed by a Member to the Company (including adjustments under
Section 48(q) of the Code) shall be determined as if the Adjusted Basis of such
property on the date of contribution was equal to the Carrying Value of such
property on such date, in accordance with Treasury Regulation Section
1.704-1(b)(2)(iv)(g);

                                (3)  Any income, gain or loss attributable to 
the taxable disposition of any asset shall be determined by the Company as if
the Adjusted Basis of such asset as of the date of disposition were equal to the
Carrying Value of such asset as of such date;

                                (4)  All fees and other expenses incurred by the
Company to promote the sale of (or to sell) an interest that can neither be
deducted nor amortized under Section 709 of the Code shall be treated as an item
of deduction.

                                (5)  The computation of all items of income, 
gain, loss, and deduction shall be made without regard to any adjustment in the
basis of Company asset as a result of an election under Section 754 of the Code
which may be made by the Company (except to the extent required by Treasury
Regulation Section 1.704-1(b)(2)(iv)(m)) and, as to those items

                                       12


described in Section 705(a)(2)(B) of the Code, without regard to the fact that
such items are neither currently deductible nor capitalizable for federal income
tax purposes; and

                                (6)  In the event that any Distribution is made
to a Member other than in cash (including liquidating Distributions), the
Capital Accounts of the Members, immediately prior to such distribution, shall
be appropriately adjusted upward or downward to reflect any Unrealized Gain or
Unrealized Loss attributable to the distributed property (determined on the
basis of the fair market value of the property at the time of distribution).

                           (c)  A transferee will succeed to the Capital Account
(or such portion thereof) relating to the interest transferred, and there shall
be no adjustment to the Capital Accounts as a result of such transfer except as
otherwise required under Treasury Regulation Section 1.704-1. If, however, the
transfer causes a termination of the Company under Section 708(b)(1)(B) of the
Code, then, to the extent required by regulations or otherwise deemed advisable
by the Tax Matters Partner, the Company's assets shall be deemed to have been
distributed in liquidation of the Company to the remaining Members (including
such transferee) and recontributed by such Members and such transferee in
reconstitution of the Company, and the Capital Accounts of the Members in such
reconstituted Company shall at such time be determined, and shall thereafter be
maintained, in accordance with the rules set forth in this Agreement.

                  Section 8.3   Special Tax Rules

                           (a)  Special Rules Relating to Contributed Property.
Solely for tax purposes (and not for Capital Account purposes), in the case of
any property (other than cash) included in a Capital Contribution, items of
income, gain, loss, deduction, and credit attributable to such contributed
property shall be allocated as follows:

                                (1)  first, among the Members in a manner that 
takes into account the variation between the fair market value of such property
and its Adjusted Basis at the time of contribution (in accordance with Section
704(c) of the Code and applicable Regulations), and

                                (2)  thereafter, in accordance with Section 7.1
and the other provisions of this Article.

                           (b)  Guaranteed Payments. Notwithstanding the 
foregoing, in the event that any fees, interest, or other amounts paid or
payable to any Member are deducted by the Company in reliance on Sections 707(a)
or 707(c) of the Code, and such fees, interest, or other amounts are disallowed
as deductions to the Company and are recharacterized as Company distributions,
there shall be allocated to such Member, prior to the allocations provided in
Section 7.1, an amount of Company gross income for the year in which such fees,
interest, or other amounts are treated as Company distributions equal to such
fees, interest, or other amounts so treated as distributions.

                           (c)  Special Overrides.

                  (1) Solely for purposes of determining a Member's Capital
Account in applying the provisions of this clause (c), the anticipated
adjustments, allocations, and distributions described in

                                       13


Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(4)-(6) shall be taken into
account, and each Member shall be deemed obligated to restore any deficit in its
Capital Account to the extent of the sum of its share of the Minimum Gain, as
determined pursuant to Treasury Regulation Section 1.704-2(g)(i), and its share
of the Partner Nonrecourse Debt Minimum Gain, as determined pursuant to Treasury
Regulation Section 1.704-2(i)(5).

                  (2) Notwithstanding any other provision of this Agreement, no
allocation of Loss, or other allocation of loss or deduction, shall be made to
any Member if such allocation would result in such Member having a negative
balance in its Capital Account at the close of any Fiscal Year in excess of the
amount it would be required to restore on a liquidation of the Company at the
close of such Fiscal Year (or a liquidation of such Member's interest in the
Company).

                  (3) Notwithstanding any other provision of this Agreement, in
the event any Member unexpectedly receives an adjustment, allocation, or
distribution described in clause (4), (5), or (6) of Treasury Regulation Section
1.704-1(b)(2)(ii)(d) that results in such Member having a negative balance in
its Capital Account at the close of any Fiscal Year in excess of the amount that
it is required to restore on a liquidation of the Company at the close of such
Fiscal Year (or of the Member's interest in the Company), or for any other
reason has a deficit Capital Account balance in excess of such amount, such
Member shall, prior to the allocations otherwise provided in this Section, be
allocated Profit (and other income and gain) in an amount and manner sufficient
to eliminate such excess as promptly as possible.

                  (4) In accordance with and pursuant to Treasury Regulation
1.704-2(i)(1), all partner nonrecourse deductions (as defined in that
Regulation) shall be allocated to the Member that bears the economic risk of
loss on the debt giving rise to such deductions as determined under that
Regulation. Further, in accordance with and pursuant to Treasury Regulation
1.704-2(f) and -2(i)(4) (and subject to the exceptions set forth therein), if
there is a net decrease in either the Company's Minimum Gain or Partner
Nonrecourse Debt Minimum Gain or both during any Fiscal Year, all Members shall
be allocated, before any other allocation is made of Profit (and other income
and gain) or Loss (or other loss or deduction) for such Fiscal Year, items of
income and gain for such Fiscal Year (and, if necessary, subsequent years) in an
amount equal to the Member's share in the decrease in Minimum Gain or Partner
Nonrecourse Debt Minimum Gain, as determined pursuant to Treasury Regulation
Sections 1.704-2(g)(2) and 1.704-2(i)(4).

                  (5) It is the intent of the parties to this Agreement that the
chargeback provisions and the limitation on loss allocations provided in this
Section satisfy the "allocation of nonrecourse liability" rules provided in
Treasury Regulation 1.704-2 and the requirements of Treasury Regulation
1.704-1(b)(2)(ii)(d) (relating to the alternate test for economic effect and
"qualified income offset"). It is further intended that the allocations under
this Section shall effect an allocation for federal income tax purposes in a
manner consistent with Section 704(b) and (c) of the Code and comply with any
limitations or restrictions therein. If for any reason the allocations contained
in this Agreement shall conflict with the Regulations promulgated under Section
704 of the Code, the Members acknowledge that such Regulations shall control.

                  (6) The allocations set forth in this Section (the "Regulatory
Allocations") are intended to comply with certain requirements of Treasury
Regulations Section 1.704-1(b). The Regulatory Allocations may not be consistent
with the manner in which the Members intend to

                                       14


divide Company Distributions. Accordingly, the Tax Matters Partner (or any
successor thereto) is hereby authorized, with the advice of the company's tax
advisers, to devise other allocations of income, gains and losses and other
items among the Members as may be necessary so as to prevent the Regulatory
Allocations from distorting the manner in which Company Distributions will be
divided among the Members; provided, however, that any change in the manner of
maintaining Capital Accounts shall not materially alter the economic agreement
between or among the Members as expressed in this Agreement without the consent
of each Member. In general, the Members anticipate that this will be
accomplished by specially allocating items of income, gain, loss and deduction
among the Members so that the net amount of the Regulatory Allocations and such
special allocations to such Member is zero. However, the Tax Matters Partner
shall have discretion to accomplish this result in any reasonable manner.

                  8.4      Accounting Decisions

                           (a)  Subject to the provisions of this Agreement, the
Tax Matters Partner will make all decisions as to accounting matters.

                           (b)  Subject to the provisions of this Agreement, the
Tax Matters Partner may cause the Company to make whatever elections the Company
may make under the Code, including the election referred to in Section 754 of
the Code to adjust the basis of Company assets.

                           (c)  The Company shall make the following elections 
on the appropriate tax returns:

                                (1)  To adopt the calendar year as the Fiscal 
Year;

                                (2)  To adopt the accrual method of accounting 
for income tax purposes and keep the Company's books and records in accordance
with GAAP;

                                (3)  If a Distribution as described in Section 
734 of the Code occurs or if a transfer of a Membership Interest described in
Section 743 of the Code occurs, upon the written request of any Member, to elect
to adjust the basis of the property of the Company pursuant to Section 754 of
the Code;

                                (4)  To elect to amortize the organizational 
expenses of the Company and the start up expenditures of the Company under
Section 195 of the Code ratably over a period of sixty months as permitted by
Section 709(b) of the Code; and

                                (5)  Any other election that the Tax Matters
Partner may deem appropriate and in the best interests of the Members. Neither
the Company nor any Member may make an election for the Company to be excluded
from the application of Subchapter K of Chapter I of Subtitle A of the Code or
any similar provisions of applicable state law, and no provisions of this
Agreement shall be interpreted to authorize any such election.

                  8.5      Tax Matters Partner. Insight shall be the "tax 
matters partner" of the Company pursuant to Section 6231(a)(7) of the Code. Any
Member who is designated as successor Tax Matters Partner shall take any action
as may be necessary to cause each other Member to

                                       15


become a "notice partner" within the meaning of Section 6223 of the Code. The
Tax Matters Partner shall not extend the statute of limitations, compromise any
tax controversy or take any other material action except after consultation with
the Members.

                  8.6      Tax Returns. The Tax Matters Partner shall cause to 
be prepared and filed all necessary federal, state and local income tax returns
for the Company. Each Member shall furnish to the Tax Matters Partner all
pertinent information in its possession relating to Company operations that is
necessary to enable the Company's income tax returns to be prepared and filed.

                  8.7      Tax Withholdings. The Company shall at all time be
entitled to make payments with respect to any Member in amounts required to
discharge any legal obligation of the Company pursuant to any provision of the
Code or any other tax provision or any provision enacted in the future imposing
a similar obligation on the Company to withhold or make payments to any
governmental authority with respect to any United States federal, state or local
tax liability of such Member arising as a result of such Member's interest in
the Company. Each such payment made to any governmental authority shall be
deemed to be a loan by the Company to such Member and shall not be deemed to be
a distribution. The amount of such payments made with respect to any Member,
plus interest at an annual rate equal to two percent plus the Company's highest
borrowing rate on each such amount from the date of each such payment until such
amount is repaid to the Company, shall be repaid to the Company by (i) deduction
from the current or next succeeding distribution or distributions otherwise
payable to such Member pursuant to this Agreement or (ii) earlier payment of
such amounts and interest by such Member to the Company.

                                   ARTICLE IX
                                    Transfers

                           No Member may transfer, sell, gift, or otherwise 
dispose of all, or any portion of, or any interest or rights in, the interest in
the Company owned by the Member without the consent of all of the Members. Each
Member hereby acknowledges the reasonableness of this prohibition in view of the
purposes of the Company and the relationship among the Members. The transfer of
any interest in the Company in violation of the prohibition contained in this
Article IX shall be deemed invalid, null and void, and of no force and effect.
Any Person to whom interests in the Company are attempted to be transferred in
violation of this Article IX shall not be entitled to vote on matters coming
before the Members, participate in the management of the Company, act as an
agent of the Company, receive Distributions or have any other rights in or with
respect to the interest in the Company. Notwithstanding the foregoing, each of
the Members hereby consents to the pledge of the interests in the Company
pursuant to the Amended and Restated Security Agreement, dated as of March 4,
1993, by and among Insight, the Lenders party thereto, Canadian Imperial Bank of
Commerce, as Documentation Agent for the Lenders, and the Bank of New York, as
Administrative Agent for the Lenders, as amended, restated, modified or
supplemented from time to time, including as a result of any increase, deferral,
renewal, extension or refinancing of the Credit Agreement, and consents to any
transfer of such interests upon any foreclosure or other exercise of remedies in
respect of such pledge.

                                       16


                                    ARTICLE X
                             Dissolution; Winding Up

                  10.1 Dissolution. The Company shall be dissolved upon the
happening of any of the following events (each, a "Dissolution Event"):

                           (a)  when the period fixed for its duration in 
                  Section 3.5 has expired;

                           (b)  upon the vote of all the Members;

                           (c)  the occurrence of an event described in Section
                  18-304 of the Delaware Act regarding bankruptcy or insolvency
                  of any Member; or

                           (d)  the entry of a decree of judicial dissolution
                  under the Delaware Act.

                  10.2     Voluntary Withdrawal. Except as expressly permitted 
in this Agreement, a Member shall not voluntarily withdraw or take any other
voluntary action which, directly or indirectly, causes a Dissolution Event.

                  10.3     Effect of Dissolution. Except as permitted by the
Delaware Act, upon dissolution the Company shall cease to carry on its business
and shall file a Certificate of Cancellation as provided in Section 18-203 of
the Delaware Act.

                  10.4     Winding Up, Liquidation and Distribution of Assets.

                           10.4.1  Upon dissolution, an accounting shall be made
by the Company's independent accountants of the accounts of the Company and of
the Company's assets, liabilities and operations, from the date of the previous
accounting until the date of the Dissolution Event. The Member appointed by the
other Member as the liquidator (the "Liquidator") shall immediately proceed to
wind up the affairs of the Company.

                           10.4.2  If the Company is dissolved and its affairs 
are to be wound up, the Liquidator shall:

                           (i)   Sell or otherwise liquidate all of the 
                                 Company's assets as promptly as practicable,

                           (ii)  Discharge all liabilities of the Company,
                                 including liabilities to Members who are
                                 creditors to the extent otherwise permitted
                                 by law, other than any liabilities to
                                 Members for distributions declared but not
                                 yet paid by the Company, and establish such
                                 reserves as may be reasonably necessary to
                                 provide for contingent liabilities of the
                                 Company,

                           (iii) Allocate any profit or loss resulting from
                                 the sales of Company assets to the Members
                                 in accordance with this Agreement, and

                                       17


                           (iv)  Distribute the remaining assets in the 
                                 following order:

                                    (1)     If any assets of the Company are to
                                            be distributed in-kind, the net fair
                                            market value of such assets as of
                                            the date of the Dissolution Event
                                            shall be determined by an
                                            independent appraisal or the Tax
                                            Matters Partner. Such assets shall
                                            be deemed to have been sold as of
                                            the date of dissolution for their
                                            fair market value, and the Capital
                                            Accounts of the Members shall be
                                            adjusted pursuant to the provisions
                                            of this Agreement to reflect such
                                            deemed sale.

                                    (2)     In accordance with Section 7.4
                                            hereof, either in cash or in-kind,
                                            as determined by the Liquidator,
                                            with any assets distributed in-kind
                                            being valued for this purpose at
                                            their fair market value in
                                            accordance with the requirements set
                                            forth in Treasury Regulation Section
                                            1.704-1(b)(2)(ii)(b)(2).

                           10.4.3  Notwithstanding anything to the contrary in 
this Agreement, upon a liquidation within the meaning of Treasury Regulation
Section 1.704-1(b)(2)(ii)(g), if any Member has a deficit Capital Account (after
giving effect to all contributions, Distributions, allocations and other Capital
Account adjustments for all Fiscal Years, including the year in which the
liquidation occurs), such Member shall have no obligation to make any
contribution to capital, and the negative balance of such Member's Capital
Account shall not be considered a debt owed by such Member to the Company or to
any other Person for any purpose whatsoever.

                           10.4.4  Upon completion of the winding up, 
liquidation and distribution of assets, the Company shall be deemed terminated.

                  10.5     Return of Contributions to Capital Nonrecourse to 
Other Members. Except as provided by law or as expressly provided in this
Agreement, upon dissolution each Member shall look solely to the assets of the
Company for the return of its Capital Contribution. If the Company property
remaining after the payment or discharge of the debts and liabilities of the
Company is insufficient to return the Capital Contributions of one or more
Members, such Member or Members shall have no recourse against any other Member.

                                   ARTICLE XI
                                 INDEMNIFICATION

                  11.1     Exculpatory Provisions. None of the Members nor any 
of their respective shareholders, members, partners, officers, directors,
employees or control persons (as such term is defined in the Securities Act of
1933, as amended, and the rules and regulations thereunder) of such Members
(collectively, the "Indemnified Persons") shall be liable directly or
indirectly, to the Company or to any other Member for any act or omission (in
relation to the Company or this Agreement) taken or omitted by such Indemnified
Person in good faith, provided that such act or omission did not constitute
gross negligence, fraud or willful violation of the law or this Agreement.

                                       18


                  11.2     Indemnification of Members. The Company shall, to the
fullest extent permitted by the Delaware Act, indemnify and hold harmless each
Indemnified Person against all claims, liabilities and expenses of whatever
nature ("Claims") relating to activities undertaken in connection with the
Company, including but not limited to amounts paid in satisfaction of judgments,
in compromise or as fines and penalties, and counsel, accountants' and experts'
and other fees, costs and expenses reasonably incurred in connection with the
investigation, defense or disposition (including by settlement) of any action,
suit or other proceeding, whether civil or criminal, before any court or
administrative body in which such Indemnified Person may be or may have been
involved, as a party or otherwise, or with which such Indemnified Person may be
or may have been threatened, while acting as such Indemnified Person, provided
that no indemnity shall be payable hereunder against any liability incurred by
such Indemnified Person by reason of such Indemnified Person's gross negligence,
fraud or willful violation of the law or this Agreement or with respect to any
matter as to which such Indemnified Person shall have been adjudicated not to
have acted in good faith.

                  11.3     Advance of Expenses. Expenses incurred by an 
Indemnified Person in defense or settlement of any Claim that may be subject to
a right of indemnification hereunder may be advanced by the Company prior to the
final disposition thereof upon receipt of an undertaking by or on behalf of the
Indemnified Person to repay such amount if it shall ultimately be determined
that the Indemnified Person is not entitled to be indemnified by the Company.

                  11.4     Control of Claim. The Company shall have the right to
select counsel (provided such counsel is reasonably satisfactory to the
Indemnified Person) and to control the defense of any action giving rise to a
Claim, provided that an Indemnified Person may nevertheless employ counsel to
represent and defend it, but the Company will not be required to pay the fees
and disbursements of more than one counsel in any jurisdiction in any proceeding
(unless by reason of potential conflicts of interest, representation by more
than one counsel is necessary). The right to control the defense of any action
shall not include the right to enter into a settlement with respect to such
action, unless such settlement is for money damages only (and the Company first
posts a bond or other security satisfactory to the Indemnified Person
sufficient, without regard to the provisions of Section 11.6, to cover the full
amount of the proposed settlement).

                  11.5     Non-Exclusivity. The right of any Indemnified Person 
to the indemnification provided herein shall be cumulative of, and in addition
to, any and all rights to which such Indemnified Person may otherwise be
entitled by contract or as a matter of law or equity and shall extend to such
Indemnified Person's successors, assigns and legal representatives.

                  11.6     Satisfaction from Company Assets. All judgments 
against the Company or an Indemnified Person, in respect of which such
Indemnified Person is entitled to indemnification, shall first be satisfied from
Company assets before the Indemnified Person is responsible therefor.

                  11.7     Notices of Claims. Promptly after receipt by an
Indemnified Person of notice of the commencement of any action or proceeding or
threatened action or proceeding involving a Claim, such Indemnified Person will,
if a claim for indemnification in respect thereof is to be made against the
Company, give written notice to the Company and each other Member of the
commencement of such action, provided that the failure of any Indemnified Person
to give notice as provided herein shall not relieve the Company of its
obligations under this Article XI, except to

                                       19


the extent that the Company is actually prejudiced by such failure to give
notice. Each such Indemnified Person shall keep the Company and each other
Member apprised of the progress of any such proceeding.

                                   ARTICLE XII
                               General Provisions

                  12.1     Notices. Any notice, demand or other communication
required or permitted to be given pursuant to this Agreement shall have been
sufficiently given for all purposes if (a) delivered personally to the party or
to an executive officer of the party to whom such notice, demand or other
communication is directed or (b) sent by registered or certified mail, postage
prepaid, addressed to the Member or the Company at its address set forth in this
Agreement. Except as otherwise provided in this Agreement, any such notice shall
be deemed to be given three business days after the date on which it was
deposited in a regularly maintained receptacle for the deposit of United States
mail, addressed and sent as set forth in this Section.

                  12.2     Amendments. This Agreement contains the entire 
agreement between the Members with respect to the subject matter of this
Agreement, and supersedes each course of conduct previously pursued or
acquiesced in, and each oral agreement and representation previously made, by
the Members with respect thereto, whether or not relied or acted upon. No course
of performance or other conduct subsequently pursued or acquiesced in, and no
oral agreement or representation subsequently made, by the Members, whether or
not relied or acted upon, and no usage of trade, whether or not relied or acted
upon, shall amend this Agreement or impair or otherwise affect any Member's
obligations pursuant to this Agreement or any rights and remedies of a Member
pursuant to this Agreement. No amendment to this Agreement shall be effective
unless made in a writing duly executed by all Members and specifically referring
to each provision of this Agreement being amended.

                  12.3     Headings. The headings in this Agreement are for
convenience only and shall not be used to interpret or construe any provision of
this Agreement.

                  12.4     Waiver. No failure of a Member to exercise, and no 
delay by a Member in exercising, any right or remedy under this Agreement shall
constitute a waiver of such right or remedy. No waiver by a Member of any such
right or remedy under this Agreement shall be effective unless made in a writing
duly executed by all Members and specifically referring to each such right or
remedy being waived.

                  12.5     Sole Member. Upon formation, there shall be only one
Member of the Company. Unless and until there is more than one Member, all
references in this Agreement to Members shall be deemed to be references to the
sole Member.

                  12.6     Severability. Whenever possible, each provision of 
this Agreement shall be interpreted in such a manner as to be effective and
valid under applicable law. However, if any provision of this Agreement shall be
prohibited by or invalid under such law, it shall be deemed modified to conform
to the minimum requirements of such law or, if for any reason it is not deemed

                                       20


so modified, it shall be prohibited or invalid only to the extent of such
prohibition or invalidity without the remainder thereof or any other such
provision being prohibited or invalid.

                  12.7     Binding. This Agreement shall be binding upon and 
inure to the benefit of all Members, and to the extent permitted by this
Agreement, their respective legal successors and assignees.

                  12.8     Counterparts. This Agreement may be executed in
counterparts, each of which shall be deemed an original and all of which shall
constitute one and the same instrument.

                  12.9     Governing Law. This Agreement shall be governed by, 
and interpreted and construed in accordance with, the laws of the State of
Delaware without regard to principles of conflict of laws.

                  12.10    Further Assurances. The Members each agree to 
cooperate, and to execute and deliver in a timely fashion any and all additional
documents and do such further acts as may be necessary to effectuate the
purposes of the Company and this Agreement.


                  IN WITNESS WHEREOF, the parties have executed this Operating
Agreement as of the date first written above.
