the requesting Member during normal business hours at the location at which such
information is normally maintained.

                           (iii) If the requested information is not in the
possession of the Company, but rather in the possession of one of the Members,
then that Member will make such information available to the requesting Member
during normal business hours at the location at which such information is
normally maintained.

                           (iv) The requesting Member shall be responsible for
the expenses relating to copies of such information, but will not be obligated
to pay for the time of employees or contractors of the producing Member.

                           (v) All information that is provided to the

sole option, (a) enforce the restriction set forth in this Section to the
maximum extent permitted under Law or in equity, or (b) may accept such

<PAGE>   14
liable to the Company and the other Member for all monetary damages (including

                                   ARTICLE IV

                        CAPITAL AND OTHER CONTRIBUTIONS

         4.1 Initial Contributions.

                  (a) Contemporaneously with the execution of this Agreement,
each Member shall:

                           (i) make the contributions to the capital of the
Company described in the Master Formation Agreement; and

                           (ii) execute and deliver, and cause its Affiliates to
execute and deliver, those Related Agreements to which it or such Affiliates are
intended to be parties.

                  (b) The Members agree that the value of the initial
contributions made by each Member is equal and that, for the purpose of any
calculation involving Cumulative Contributions in connection with a Conversion
under Section 4.5(d), the value of each Member's initial contributions shall be
deemed to be US $3,200,000.

                  (c) The initial Capital Contribution of Humko will be made in
cash in the amount of US $3,200,000.

                  (d) The initial Capital Contribution of InCon will be made (i)
by the assignment to the Company of certain assets owned by InCon and others,
the value of which has been agreed upon by InCon and Humko to be US $6,000,000,
and (ii) by the payment by InCon to the Company of US $200,000 cash. On the date
hereof, the Company has paid to InCon US $3,000,000 in payment for a one-half
(1/2) undivided interest in the non-cash assets conveyed by InCon to the
Company. The other one-half (1/2) undivided interest in the non-cash assets
conveyed by InCon to the Company shall constitute a Capital Contribution by
InCon to the Company equal to US $3,000,000. InCon has additionally paid to the
Company a sum of money to cover payment of certain accounts payable that have
been assigned by InCon to the Company (which shall constitute a reimbursement to
the Company and not a contribution), but that were required to be paid by the
Company from funds provided by InCon to the Company under the terms of the
Master Formation Agreement.

                  (e) After the distribution of US $3,000,000 to InCon on the
date hereof, the remaining US $400,000 of cash of the Company shall be used as
directed by the Management Committee; provided, however, that none of such funds
may be expended by the Company (except for normal operations not exceeding in
the aggregate $300,000) until [*].

                                       9
<PAGE>   15
         4.2 Subsequent Capital Contributions

                  (a) Except as otherwise provided in this Agreement, no
subsequent contributions by the Members shall be made without the prior written
consent of both Members. Except as provided in Section 4.2(b) and Section 4.5,
neither Member is required to make any contributions to the Company other than
pursuant to Section 4.1.

                  (b) Without creating any rights in favor of any third party,
to the extent that the Members mutually agree to make any Capital Contributions
to the Company, each Member shall be obligated to contribute such amounts to the
Company in accordance with such agreement.

                  (c) Except as set forth above and as elsewhere expressly
provided in this Agreement, (i) in no event shall the payment of any amount by
any Member to the Company or the other Member pursuant to a requirement of
indemnification under this Agreement or any of the Related Agreements be
considered a contribution of capital to the Company, and (ii) no Member shall be
required to make any additional contributions to the Company.

         4.3 Failure to Contribute. If a Member (the "Delinquent Member") does
not pay to the Company all or any portion of a Capital Contribution that is
required to be paid pursuant to Sections 4.1 or 4.2, the Company, upon written
request by the other Member, shall exercise one or more of the following
remedies, as specified by the other Member, and shall provide notice thereof to
the Delinquent Member:

                           (i) charging interest on the unpaid portion of such
required payment at an annual rate equal to the lesser of (i) the Agreed
Interest Rate plus three percent (3%) or (ii) the maximum rate permitted by
applicable Law, from the date that such payment was due until the date that it
is made;

                           (ii) taking such action as the other Member may deem
appropriate to obtain payment by the Delinquent Member of the required payment,
including withholding any distributions otherwise payable to the Delinquent
Member;

                           (iii) permitting (but not requiring) the other Member
(the "Lending Member") to deliver to the Company all or any portion of the
Delinquent Member's unpaid required payment, with the following results:

                                    (A) the sum delivered shall constitute a
loan from the Lending Member to the Delinquent Member pursuant to the applicable
provisions of this Agreement;

                                    (B) the principal balance of such loan and
all accrued unpaid interest thereon shall be due and payable in whole by the
Lending Member to the Delinquent Member on or before one (1) year from the date
of such loan;

                                       10
<PAGE>   16
                                    (C) the unpaid principal balance of such
loan shall bear interest at an annual rate equal to the lesser of (i) the Agreed
Interest Rate plus three percent (3%), or (ii) the maximum rate permitted by
applicable Law, from the date that such loan is made until the date that the
principal balance, together with all interest accrued thereon, is repaid to the
Lending Member;

                                    (D) all distributions from the Company that
otherwise would be made to the Delinquent Member (whether before or after
dissolution of the Company) instead shall be paid to the Lending Member, for
credit against: first, all costs incurred by the Lending Member in enforcing
payment of its loan by the Delinquent Member (including, without limitation,
attorneys' fees and court costs); second, the unpaid and accrued interest on
such loan; and third, the unpaid principal balance of such loan, until all such
costs, such principal balance and all such interest shall have been paid in full
to the Lending Member, but all such payments to the Lending Member shall be
treated for all other purposes of this Agreement as a distribution to the
Delinquent Member;

                                    (E) the repayment of the principal balance
and interest accrued thereon shall be secured by a security interest in the
Delinquent Member's Membership Interest, as more fully set forth in Section 4.4;
and

                                    (F) the Lending Member shall have the right
(in addition to the other rights and remedies granted to it pursuant to this
Agreement or available to it at Law or in equity) to take, after five Business
Days' advance written notice to the Delinquent Member, such action (including
court proceedings) as the Lending Member may deem appropriate to obtain payment
by the Delinquent Member of the principal balance of such loan and all interest
accrued thereon, at the cost and expense of the Delinquent Member;

                           (iv) exercising the rights of a secured party under
the Uniform Commercial Code of the State of Delaware, as more fully set forth in
Section 4.4; or

                           (v) exercising any other rights and remedies
available at Law or in equity.

         4.4 Security Agreement. Each Member (as a Delinquent Member) hereby
grants to the other Member (as a Lending Member) a security interest in, and a
first lien on, its Membership Interest and the proceeds thereof, under the
Uniform Commercial Code of the State of Delaware to secure any and all loans
made by the Lending Member to the Delinquent Member pursuant to Section
4.3(iii), together with interest thereon as provided in Section 4.3(iii)(C). In
addition, InCon hereby grants to Humko a security interest in, and a first lien
on, its Membership Interest and the proceeds thereof, under the Uniform
Commercial Code of the State of Delaware to secure its obligations under the
terms and provisions of Section 4.7 of this Agreement and under Section 7.6 of
the Master Formation Agreement, and upon failure by, or refusal of, InCon to pay
any of the amounts required to be paid under the terms of Section 4.7 of this
Agreement or to perform any of its obligations under Section 7.6 of the Master
Formation Agreement, Humko is entitled to all the rights and remedies of a
secured party under the Uniform Commercial Code of the State of Delaware with
respect to the security interest granted in this Section 4.4. On any

                                       11
<PAGE>   17
default by a Member in making a required payment to the Lending Member pursuant
to Section 4.3(iii)(B), the Lending Member is entitled to all the rights and
remedies of a secured party under the Uniform Commercial Code of the State of
Delaware with respect to the security interest granted in this Section 4.4.
Contemporaneously with the execution and delivery of this Agreement and from
time- to-time thereafter, each Member shall execute and deliver to the other
Member (and hereby appoints the other Member as its attorney-in-fact for the
purpose of such execution and delivery) all financing statements and other
instruments as the Lending Member may reasonably request to effectuate and carry
out the preceding provisions of this Section 4.4.

         4.5 Special Cash Calls. If the Company is unable to meet its
obligations as and when they come due and has exhausted all other sources of
funds reasonably available to it including, without limitation, additional
Member loans pursuant to Section 7.4 hereof, then either Member may make a
request (a "Special Cash Call") that both Members provide a specified amount of
additional funds to the Company in proportion to their respective Sharing Ratios
sufficient to meet the Company's immediate cash needs.

                  (a) If both Members agree to provide such additional funds
within 10 days of the date of a Special Cash Call, the Members shall make
additional Capital Contributions as provided in Section 4.2, or loans to the
Company as provided in Section 7.4, as they may agree. Any amounts contributed
or loaned pursuant to this Section 4.5(a) must be in proportion to the Members'
respective Sharing Ratios.

                  (b) If one Member (the "Declining Member") does not agree,
within 10 days of its receipt of a Special Cash Call, to provide its share of
funds requested pursuant to the Special Cash Call, then the other Member may, at
its option, advance to the Company the entire amount of both its share of the
Special Cash Call and the Declining Member's share of the Special Cash Call, on
the following basis:

                           (i) The sum advanced will constitute a loan (a "Cash
Call Loan") from the Lending Member to the Company.

                           (ii) The principal balance of a Cash Call Loan and
all accrued unpaid interest thereon will be due and payable in whole on or
before eighteen months from the date of such loan.

                           (iii) The amount of a Cash Call Loan will bear
interest at an annual rate equal to the lesser of (i) the Agreed Interest Rate
plus three percent (3%) or (ii) the maximum rate permitted by applicable Law,
such interest to be calculated from the date that a Cash Call Loan is made until
the date that such Cash Call Loan is repaid to the Lending Member.

                           (iv) The Company shall pay the interest on such Cash
Call Loan monthly, provided that it has funds available to do so.

                           (v) Notwithstanding the provisions of Article VI,
until such Cash Call Loan is repaid in full or converted into equity pursuant to
Section 4.5(d):

                                    (A) No distributions shall be made to either
Member,

                                       12
<PAGE>   18
                                    (B) All Net Available Cash shall be paid to
the Lending Member to repay a Cash Call Loan (applied first to accrued and
unpaid interest, and second to principal),

                                    (C) no payments shall be made by the Company
with respect to any other loan to the Company by either Member, and

                                    (D) No further capital expenditures may be
made except for amounts required (i) by contract, (ii) to comply with
environmental, health or safety requirements, (iii) for routine maintenance,
(iv) for emergency repairs, (v) to preserve and protect partially completed
capital projects; or (vi) as otherwise approved by the Management Committee.

Notwithstanding the foregoing, while a Cash Call Loan is outstanding, the
Company shall pay all amounts due to Members and their Affiliates for goods or
services provided to the Company, to the extent that funds are available to make
such payments.

                  (c) At any time at which a Cash Call Loan is outstanding, the
Declining Member may pay to the Lending Member its share of the outstanding
balance of a Cash Call Loan (including any accrued and unpaid interest), in
exchange for a proportionate share of such Cash Call Loan.

                  (d) At any time after a Cash Call Loan is due and payable in
full, the Lending Member shall have the option, exercisable in its sole
discretion upon 180 days' prior written notice to the Declining Member, to
convert all or any portion of its Cash Call Loan (excluding any accrued and
unpaid interest thereon) to a Capital Contribution (the "Conversion"). If the
Declining Member does not pay its share of the outstanding balance of a Cash
Call Loan (including any accrued and unpaid interest) within 180 days after the
Lending Member's notice, the Conversion shall become effective, with the
following results:

                           (i) The Lending Member's Sharing Ratio shall be
adjusted to equal the percentage determined by a fraction, the numerator of
which is the sum of (A) the Lending Member's Cumulative Contributions
immediately preceding the Conversion plus (B) the outstanding principal and
accrued but unpaid interest of a Cash Call Loan converted hereunder, and the
denominator of which is the sum of (X) both Members' Cumulative Contributions
immediately preceding the Conversion plus (Y) the outstanding principal and
accrued but unpaid interest of a Cash Call Loan converted hereunder.

                           (ii) The Declining Member's Sharing Ratio shall be
adjusted to equal the percentage determined by a fraction, the numerator of
which is the Declining Member's Cumulative Contributions immediately preceding
the Conversion and the denominator of which is the sum of (X) both Members'
Cumulative Contributions immediately preceding the Conversion plus (Y) the
outstanding principal and accrued but unpaid interest of a Cash Call Loan
converted hereunder.

<PAGE>   19
         4.6 Return of Contributions. A Member is not entitled to the return of
any part of its Capital Contributions or to be paid interest in respect of
either its capital account or its Capital Contributions. An unrepaid Capital
Contribution is not a liability of the Company or of any Member. A Member is not
required to contribute or to lend any cash or property to the Company to enable
the Company to return any Member's Capital Contributions. The foregoing
provisions of this Section 4.6 do not limit the Members from agreeing to
distribute capital of the Company or from receiving distributions of capital
upon the liquidation of the Company in accordance with Section 12.1. All of the
provisions of this Section are subject to the terms and provisions of Section
4.7.

         4.7 Special Humko Provisions. Notwithstanding anything to the contrary
contained in this Agreement, if EBITDA is less than US $1,500,000 for the period
commencing one (1) calendar year after the date hereof and ending on the date
which is two (2) calendar years after the date hereof, InCon is obligated under
the terms and provisions of the Master Formation Agreement to pay to Humko two
hundred percent (200%) of the difference between US $1,500,000 and the actual
amount of EBITDA for such period, but in no event shall InCon be required to pay
Humko more than US $600,000 plus accrued and unpaid interest from the date due
until paid in accordance with the terms of the Master Formation Agreement. The
obligation to pay such amount to Humko shall be secured in the same manner as a
loan under the terms and provisions of Section 4.4, and Humko shall be deemed to
be a Lending Member and InCon a Delinquent Member under Sections 4.3 and 4.4 for
purposes of this Section 4.7 only, but such amount shall be payable upon demand
by Humko and shall not be subject to the term or interest rate applicable to a
loan under Section 4.3. In addition, if InCon fails to pay Humko such amount
when and if due in accordance with the provisions of the Master Formation
Agreement, then (i) all distributions to be made to InCon under the terms of
this Agreement shall be paid to Humko until the entire sum owed to Humko has
been paid in full, (ii) Humko shall be entitled to exercise any of the remedies
provided to the Lending Member under the terms and provisions of Section 4.5(b),
and (iii) the entire US $600,000 together with all accrued and unpaid interest
thereon or such portion thereof that InCon is obligated to pay to Humko but
fails to pay shall be deemed to be a Cash Call Loan for purposes of Conversion
only under Section 4.5(d) and shall be deemed to be due and payable upon failure
of InCon to pay all or any part of such amount when due under the Master
Formation Agreement. Without limiting the generality of the foregoing, (i) Humko
shall be entitled to the Conversion referred to in Section 4.5(d) immediately
upon failure of InCon to pay all or any portion of such amounts notwithstanding
anything to the contrary contained in Section 4.5(d), and (ii) all of the terms
and provisions of Section 4.5(b)(v) shall be applicable to the portion of the
foregoing amounts that remain unpaid in the same manner as if such amounts
constituted a Cash Call Loan.

authority to the Chief Executive Officer pursuant to Section 5.3. The Company
will not have "managers," as that term is used in the Act, it being understood
that the Representatives, the Chief Executive Officer and the other Officers do
not constitute "managers."

         5.2 Management Committee. The Members shall act collectively through
meetings as a "committee of the whole," which is hereby named the "Management
Committee". Decisions or actions taken by the Management Committee in accordance
with the provisions of this Agreement shall constitute decisions or actions by
the Company and shall be binding on each Member, Representative, Officer and
employee of the Company. The Management Committee shall conduct its affairs in
accordance with the following provisions and the other provisions of this
Agreement:

                  (a)      Representatives.

                           (i) Designation. To facilitate the orderly and
                  efficient conduct of Management Committee meetings, each
                  Member shall notify the other Members, from time to time, of
                  the identity of (A) one of its Officers, employees or agents
                  who will represent it at such meetings (a "Representative"),
                  and (B) one of its Officers, employees or agents who will
                  represent it at any meeting that the Member's Representative
                  is unable to attend (an "Alternate Representative") (the term
                  "Representative" shall also refer to any Alternate
                  Representative that is actually performing the duties of the
                  applicable Representative.). The initial Representative of
                  Humko shall be Daniel S. Antonelli and the initial
                  Representative of InCon shall be Ronald H. Lane. A Member may
                  designate a different Representative or Alternate
                  Representative for any meeting of the Management Committee by
                  notifying each of the other Members at least three Business
                  Days prior to the scheduled date for such meeting; provided,
                  however, that if giving such advance notice is not feasible,
                  then such new Representative or Alternate Representative shall
                  present written evidence of his or her authority at the
                  commencement of such meeting.

                           (ii) Authority. Each Representative shall have the
                  full authority to act on behalf of the Member that designated
                  such Representative; the action of a Representative at a
                  meeting (or through a written consent) of the Management
                  Committee shall bind the Member that designated such
                  Representative; and the other Members shall be entitled to
                  rely upon such action without further inquiry or investigation
                  as to the actual authority (or lack thereof) of such
                  Representative. In addition, the act of an Alternate
                  Representative shall be deemed the act of the Representative
                  for which such Alternate Representative is acting, without the
                  need to produce evidence of the absence or unavailability of
                  such Representative.

                           (iii) Disclaimer of Duties; Indemnification. EACH
                  REPRESENTATIVE SHALL REPRESENT, AND OWE DUTIES TO, ONLY THE
                  MEMBER THAT DESIGNATED SUCH REPRESENTATIVE (THE NATURE AND
                  EXTENT OF SUCH DUTIES BEING AN INTERNAL CORPORATE AFFAIR OF
                  SUCH MEMBER), AND NOT TO THE

                                       15
<PAGE>   21
                  COMPANY, ANY OTHER MEMBER OR REPRESENTATIVE, OR ANY OFFICER OR
                  EMPLOYEE OF THE COMPANY. THE PROVISIONS OF SECTION 5.2(f)(ii)
                  SHALL ALSO INURE TO THE BENEFIT OF EACH MEMBER'S
                  REPRESENTATIVE. THE COMPANY SHALL INDEMNIFY, PROTECT, DEFEND,
                  RELEASE AND HOLD HARMLESS EACH REPRESENTATIVE FROM AND AGAINST
                  ANY CLAIMS ASSERTED BY OR ON BEHALF OF ANY PERSON (INCLUDING
                  ANOTHER MEMBER), OTHER THAN THE MEMBER THAT DESIGNATED SUCH
                  REPRESENTATIVE, THAT ARISE OUT OF, RELATE TO OR ARE OTHERWISE
                  ATTRIBUTABLE TO, DIRECTLY OR INDIRECTLY, SUCH REPRESENTATIVE'S
                  SERVICE ON THE MANAGEMENT COMMITTEE.

                           (iv) Attendance. Each Member shall use all reasonable
                  efforts to cause its Representative or Alternate
                  Representative to attend each meeting of the Management
                  Committee, unless its Representative is unable to do so
                  because of a "force majeure" event or other event beyond his
                  or her reasonable control, in which event such Member shall
                  use all reasonable efforts to cause its Representative or
                  Alternate Representative to participate in the meeting by
                  telephone pursuant to Section 5.2(h).

                  (b) Chairman and Secretary. One of the Representatives will be
         designated as Chairman of the Management Committee, in accordance with
         this Section 5.2(b), to preside over meetings of the Management
         Committee. The Chairman shall be the Representative of Humko in
         odd-numbered calendar years and of InCon in even-numbered calendar
         years. The Representative of Humko designated as Chairman initially
         shall be Daniel S. Antonelli. The Management Committee shall also
         designate a Secretary of the Management Committee, who need not be a
         Representative.

                  (c) Procedures. The Secretary of the Management Committee
         shall maintain written minutes of each of its meetings, which shall be
         submitted for approval no later than the next regularly-scheduled
         meeting. The Management Committee may adopt whatever rules and
         procedures relating to its activities as it may deem appropriate,
         provided that such rules and procedures shall not be inconsistent with
         or violate the provisions of this Agreement.

                  (d) Time and Place of Meetings. The Management Committee shall
         meet quarterly subject to more or less frequent meetings upon approval
         of the Management Committee. Notice of, and an agenda for, all
         Management Committee meetings shall be provided by the Chairman to all
         Members at least ten days prior to the date of each meeting, together
         with proposed minutes of the previous Management Committee meeting (if
         such minutes have not been previously ratified). Special meetings of
         the Management Committee may be called at such times, and in such
         manner, as any Member deems necessary. Any Member calling for any such
         special meeting shall notify the Chairman, who in turn shall notify all
         Members of the date and agenda for such meeting at least ten days prior
         to the date of such meeting. Such ten-day period may be shortened by
         the Management Committee, acting through a Unanimous Interest. All

                                       16
<PAGE>   22
         meetings of the Management Committee shall be held at a location
         designated by the Chairman. Attendance of a Member at a meeting of the
         Management Committee shall constitute a waiver of notice of such
         meeting, except where such Member attends the meeting for the express
         purpose of objecting to the transaction of any business on the ground
         that the meeting is not lawfully called or convened.

                  (e) Quorum. The presence of a Majority Interest shall
         constitute a quorum for the transaction of business at any meeting of
         the Management Committee.

                  (f) Voting.

                           (i) Voting by Voting Ratios; Voting Thresholds.
                  Except as provided otherwise in this Agreement, voting shall
                  be according to the Members' respective Voting Ratios. Set
                  forth below are definitions of the principal voting thresholds
                  that are required to approve certain actions:

                                    (A) "Unanimous Interest" means all of the
                           Members; and

                                    (B) "Majority Interest" means Members
                           holding among them at least a majority of the Voting
                           Ratios.

                  Except for matters that require the approval of a Unanimous
                  Interest, the vote of a Majority Interest shall constitute the
                  action of the Management Committee.

                           (ii) DISCLAIMER OF DUTIES. WITH RESPECT TO ANY VOTE,
                  CONSENT OR APPROVAL AT ANY MEETING OF THE MANAGEMENT COMMITTEE
                  OR OTHERWISE UNDER THIS AGREEMENT, EACH MEMBER MAY GRANT OR
                  WITHHOLD SUCH VOTE, CONSENT OR APPROVAL (A) IN ITS SOLE AND
                  ABSOLUTE DISCRETION, (B) WITH OR WITHOUT CAUSE, (C) SUBJECT TO
                  SUCH CONDITIONS AS IT SHALL DEEM APPROPRIATE, AND (D) WITHOUT
                  TAKING INTO ACCOUNT THE INTERESTS OF, AND WITHOUT INCURRING
                  LIABILITY TO, THE COMPANY, ANY OTHER MEMBER OR REPRESENTATIVE,
                  OR ANY OFFICER OR EMPLOYEE OF THE COMPANY (COLLECTIVELY, "SOLE
                  DISCRETION"). THE PROVISIONS OF THIS SECTION 5.2(f)(ii) SHALL
                  APPLY NOTWITHSTANDING THE NEGLIGENCE, GROSS NEGLIGENCE,
                  WILLFUL MISCONDUCT, STRICT LIABILITY OR OTHER FAULT OR
                  RESPONSIBILITY OF A MEMBER OR ITS REPRESENTATIVE.

                  (g) Action by Written Consent. Any action required or
         permitted to be taken at a meeting of the Management Committee may be
         taken without a meeting, without prior notice, and without a vote if a
         consent or consents in writing, setting forth the action so taken, is
         signed by Members that could have taken the action at a meeting of the
         Management Committee at which all Members entitled to vote on the
         action were represented and voted.

                  (h) Meetings by Telephone. Members may participate in and hold
         such meeting by means of conference telephone, video conference or
         similar communications equipment by means of which all persons
         participating in the meeting can hear each other. Participation in such
         a meeting shall constitute presence in person at such meeting, except
         where a Member participates in the meeting for the express purpose of
         objecting to the transaction of any business on the ground that the
         meeting is not lawfully called or convened.

                  (i) Matters Requiring Management Committee Approval.
         Notwithstanding any other provision of this Agreement, no actions may
         be taken by, or on behalf of, the Company (including by the Chief
         Executive Officer or Chief Operating Officer) without first obtaining
         the vote of a Majority Interest of the Management Committee. Included,
         without limitation, in those actions that require the vote of a

                           (vi) approving the annual Budget for the Company
                  (with it being understood that the last approved Budget shall
                  be used, and deemed approved, for any subsequent period until
                  the new Budget for that period is so approved), including the
                  parameters within which the Chief Executive Officer or Chief
                  Operating Officer is authorized to expend Company funds

                  US $100,000 over the term of such contract or agreement
                  (taking into account any permitted renewals or extensions
                  thereof) or (3) which is not being entered into the Ordinary
                  Course of Business.

                           (viii) causing or permitting the Company to cancel,

                  an Affiliate of any of the foregoing, or a Person related by
                  blood or marriage to any of the foregoing;

                           (x) causing or permitting the Company to enter into
                  or engage in any transaction, contract, agreement or
                  arrangement that (i) is unrelated to the Company's purpose (as
                  set forth in Section 2.4), (ii) otherwise contravenes the
                  Certificate or this Agreement, (iii) would make it impossible
                  to carry on the Ordinary Course of Business of the Company, or

                           (xiii) causing or permitting the Company to become
                  Bankrupt under the United States Bankruptcy Code (but this
                  provision shall not be construed to require any Member to
                  ensure the profitability or solvency of the Company).

                  (j) Subcommittees. The Management Committee may create such
         subcommittees, delegate to such subcommittees such authority and
         responsibility, and rescind any such delegations, as it may deem
         appropriate.

                  (k) Officers. The Management Committee may designate one or
         more persons to be Officers of the Company (the "Officers"). Any
         Officers so designated shall have such titles and, subject to the other
         provisions of this Agreement, have such authority and perform such
         duties as the Management Committee may delegate to them and shall serve
         at the pleasure of the Management Committee.

         to all Members (which resignation shall become effective 90 days after
         delivery of such notice, unless an earlier or later effectiveness is
         agreed to by such Officer and the Management Committee); (v) any such
         Officer shall commit gross negligence or willful misconduct in the
         management of the Company and, as a consequence, shall be removed as
         Chief Executive Officer, Chief Operating Officer, Chief Financial
         Officer or Chief Technology Officer by the Management Committee, acting
         by a vote of a Majority Interest at a meeting called for such purpose

         Management Committee, unless an earlier or later effectiveness is
         agreed to by the Management Committee); or (vi) the respective
         employment agreement of any such Officer with the Company has been

         Majority Interest, shall designate another person (that consents to
         serve as such) as a successor to any such Officer so removed.
         Notwithstanding anything to the contrary contained in this Agreement,

         Company.

                  (b) Duties and Authority.

                           (i) Except for decisions and actions that are to be
                           made by the Management Committee pursuant to Section
                           5.2(i) or another express provision of this

                           by the Management Committee. Without limiting the
                           generality of the foregoing, all such Officers shall
                           comply at all time with all Laws.

indemnify, defend and hold harmless each Member from and against any Claims and
Expenses incurred by such Member (i) as a result of its status as a Member or
owner of the Company, or (ii) by reason of any acts, omissions or alleged acts
or omissions arising out of or purportedly arising out of its activities as a
Member on behalf of the Company or activities of the Company; provided, however,
that in the case of (ii), the acts, omissions or alleged acts and omissions upon
which such Claims and Expenses are based were undertaken by such Member in good
faith and consistent with any applicable standard of care set forth in any
Related Agreement, were not outside of the scope of authority conferred upon
such Member by this Agreement or a Related Agreement, and were not performed or
omitted fraudulently or in bad faith or as a result of gross negligence or
willful misconduct by such Member. The foregoing indemnification specifically
includes all Claims and Expenses caused or alleged to be caused by the sole,

disposition of such Claim or Expense in connection with the investigation or
defense of a Claim or Expense (including civil or criminal action, suit,
proceeding or claim) to which it is entitled to indemnification, shall be paid
by the Company no less frequently than quarterly, provided (i) such Claim or
Expense relates to the performance of duties or services by the Member on behalf
of the Company or asserts liability against the Member as a result of its status
as a member or owner of the Company, and (ii) the Company receives an
undertaking by or on behalf of such Member to repay such amount unless it shall
ultimately be determined that such Member is entitled to be indemnified by the
Company as authorized by this Section, together with the undertaking of the
ultimate corporate parent of such Member of its obligations under such
undertaking.

                  (c) Any amounts payable to a Member pursuant to this Section
10.1 are recoverable only out of the assets of the Company and not from the
Members.

                  (d) Notwithstanding the provisions of this Section 10.1, no
Member shall be indemnified for any liability imposed by judgment, or a cost
associated therewith, including attorneys' fees, arising from or out of a
violation of any applicable Law, including any state or federal securities Laws
or rules, to the extent such indemnification is prohibited thereby.

                  (e) For purposes of this Section 10.1, the term "Member" shall
be deemed to include any Affiliate or Associate of such Member, and any owner,

Associates.

MATTER ARISING FROM OR RELATED TO SUCH EMPLOYEE'S EMPLOYMENT WITH INCON WHILE

directors, officers, agents, partners and employees, subject to the terms and
provisions of Section 5.3(d) relating to gross negligence or willful misconduct
of Officers.

                                   ARTICLE XI

                      DISPOSITIONS OF MEMBERSHIP INTERESTS

         11.1 Dispositions of Membership Interests.

                  (a) Except as expressly permitted under this Article and
elsewhere in this Agreement including, without limitation, Section 4.5(d), a
Member may not Dispose of all or any portion of its Membership Interest in the
Company, except with the prior written consent of the other Member, which
consent may be granted or withheld in the Member's sole and absolute discretion,
with or without cause, and subject to such conditions as it shall deem
appropriate. Any attempted Disposition of all or any portion of a Membership
Interest, other than in strict accordance with this Article, shall be null and
void ab initio.

                  (b) For purposes of this Article XI only and subject to
Section 11.2, the terms "Disposition" or "Dispose" shall not include any sale,
assignment, transfer, conveyance or other disposition of any Membership Interest
to any Affiliates of a Member or any corporate reorganization involving only an
Affiliate or Affiliates of a Member.

         11.2 Change of Control of InCon. For purposes of this Article XI, a
Disposition of shares or other ownership interest in InCon or the sole
shareholder of the capital stock of InCon, which results in a change of control
of InCon shall be deemed to constitute an assignment of InCon's Membership
Interest in the Company.

         11.3 Preferential Right on Sales of Membership Interests. Subject to
the other provisions of this Article XI, either Member may Dispose of all of its
Membership Interest in accordance with this Section 11.3. Should either Member
at any time desire to Dispose of all (but no Member may Dispose of part of its
Membership Interest) of its Membership Interest, such Member (the "First
Member") shall promptly give notice thereof (the "Preferential Notice") to the
other Member (the "Second Member"). The Preferential Notice shall set forth all
relevant information in respect of the proposed Disposition, including without
limitation the name and address of the prospective transferee, the purchase
price, the terms of payment, and the proposed closing date. The Second Member
shall have the following rights (which shall be exercised by written notice to
the First Member given no later than thirty (30) days after the Second Member's
receipt of the Preferential Notice): (i) the preferential right to acquire, at
the same purchase price and upon the same terms and conditions as set forth in
the Preferential Notice, the Membership

                                       30
<PAGE>   36
Interest of the First Member, or (ii) the right to consent to the proposed
Disposition to the party identified in the Preferential Notice upon the exact
terms and conditions set out in the Preferential Notice. If the optional right
described in the immediately preceding clause (i) is not exercised within such
thirty (30) day period, then the First Member may Dispose of its Membership
Interest to the prospective transferee named in the Preferential Notice for the
same purchase price and upon the same terms and conditions as therein set forth,
provided such transaction is consummated within sixty (60) days after the Second
Member's receipt of the Preferential Notice. Thereafter the First Member may not
consummate such transaction without again complying with the provisions of this
Section 11.3. As a condition to the validity of any sale of an interest in the
Company to a third party pursuant to this Section 11.3, prior to or concurrently
with the closing of such sale such third party shall execute such documents as
the Second Member may reasonably require pursuant to which the third party
becomes bound by all terms and provisions of this Agreement. Following any such
sale, the First Member shall be relieved of future liability hereunder, but
shall not be relieved of any liabilities arising prior to such sale. Any closing
of a sale of an interest from one Member to another pursuant to this Section
11.3 shall be held in accordance with the terms and provisions relative thereto
set forth in the Preferential Notice.

         11.4 Buy-Sell Options. All the terms and provisions of this Article XI
are subject to the rights of the Members under Article XIV. Without limiting the
generality of the foregoing, any Member may exercise the rights set forth in
Article XIV notwithstanding the existence of a Preferential Notice.

                                   ARTICLE XII

                           DISSOLUTION OF THE COMPANY

         12.1 Dissolution. The affairs of the Company shall be wound-up (and
the Company dissolved and liquidated upon completion of such winding up) on the
first to occur of the following events:

                  (a) the unanimous consent of the Members;

                  (b) entry of a decree of judicial dissolution of the Company
under Section 18-802 of the Act;

                  (c) subject to Article XIV (and to the extent permitted by
applicable Law), the bankruptcy (as defined in Section 18-304 of the Act) or
dissolution of either Member (upon the occurrence of such a bankruptcy and prior
to the winding-up of the Company, the non-bankrupt Member shall have the right
to exercise the option described in Section 12.5);

                  (d) subject to Article XIV, at the written election of either
Member delivered to the other Member in accordance with the provisions of
Article XIII, following the Members' failure to resolve a Deadlock Event; or

                                       31
<PAGE>   37
                  (e) subject to Article XIV, at the written election of a
non-defaulting Member if the other Member defaults in the performance of any
material obligation under this Agreement or the Master Formation Agreement and
such defaulting Member has not cured such default within 30 days, with respect
to defaults under this Agreement, and 30 days, with respect to defaults under
the Master Formation Agreement, of its receipt of a notice specifying such
default.

         12.2 Deficit Capital Accounts. No Member shall be required to pay to
the Company, to any other Member or to any third party, any deficit balance that
may exist from time to time in such Member's capital account.

         12.3 Winding-Up.

                  (a) On the occurrence of an event described in Section 12.1,
the Management Committee shall appoint a liquidator by vote of Majority
Interest. The liquidator shall proceed diligently to wind up the affairs of the
Company and make final distributions as provided herein and in the Act. The
costs of winding up shall be borne as a Company expense. Until final
distribution, the liquidator shall continue to operate the Company properties
with all of the power and authority of the Members. The steps to be accomplished
by the liquidator are as follows:

                  (i) as promptly as possible after dissolution and again after
         final winding up, the liquidator shall cause a proper accounting to be
         made by a recognized firm of certified public accountants of the
         Company's assets, liabilities, and operations through the last calendar
         day of the month in which the dissolution occurs or the final winding
         up is completed, as applicable;

                  (ii) the liquidator shall discharge from Company funds all of
         the indebtedness and other debts, liabilities and obligations of the
         Company (including all expenses incurred in winding up and any loans
         described in Sections 4.3 and 4.5) or otherwise make adequate
         provision for payment and discharge thereof (including the
         establishment of a cash escrow fund for contingent liabilities in such
         amount and for such term as the liquidator may reasonably determine);
         and

                  (iii) all remaining assets of the Company shall be distributed
         to the Members in accordance with their Sharing Ratios.

                  (b) All assets of the Company shall be sold by the liquidator
and may be sold to Members, and the net proceeds derived from any such sale
shall be applied and distributed in the following order of priority:

                  (i) First, to the payment of any debts and liabilities of the
         Company; and

                  (ii) Second, in the order and in the proportions set forth in
         Section 6.2.

                  (c) The distribution of cash or property to a Member in
accordance with the provisions of this Section 12.3 constitutes a complete
return to the Member of its Capital

                                       32
<PAGE>   38
Contributions and a complete distribution to the Member of its Membership
Interest and all the Company's property and constitutes a compromise to which
all Members have consented pursuant to Section 18-502(b) of the Act. To the
extent that a Member returns funds to the Company, it has no claim against any
other Member for those funds.

                  (d) On completion of such final distribution, the Members
shall file a Certificate of Cancellation with the Secretary of State of
Delaware, cancel any other filings made pursuant to Section 2.5, and take such
other actions as may be necessary to terminate the existence of the Company.

         12.4 Effect of Dissolution on the Transition Services Agreement. Upon
the occurrence of any dissolution of the Company pursuant to Section 12.1, the
Transition Services Agreement shall be terminated.

         12.5 Bankruptcy Remedies. Upon the bankruptcy (as defined in Section
18-304 of the Act) or dissolution of a Member, prior to the winding up of the
Company, the other Member shall have the sole and exclusive authority to manage
the Company and shall, further, have the right to elect to have the Company
continue its business, rather than be dissolved and liquidated.

         12.6 No Consequential Damages. Except as expressly set forth in this
Agreement or the Related Agreements, no Member shall be responsible for any lost
profits or other consequential damages arising as a result of the breach of this
Agreement or any of the Related Agreements. In addition, no termination of the
Company shall relieve any Member from its indemnification obligations under this
Agreement or the Related Agreements.

                                  ARTICLE XIII

                         DEADLOCK RESOLUTION PROCEDURES

         13.1 Notice of Deadlock Issue. If the Members are in disagreement over
an issue that falls within the definition of Deadlock Issue, either Member may
initiate the procedures provided in this Article XIII by giving written notice
to the other Member and calling a special meeting in accordance with Section
13.2.

         13.2 Special Meeting of Members. A special meeting of the Members to
consider the Deadlock Issue shall be convened not less than 30 days, nor more

         13.3 Post-Meeting Time Period to Resolve Deadlock Issue. If the
Deadlock Issue remains unresolved after the date established by the notifying
Member in its notice delivered pursuant to Section 13.1, the Members shall
attempt to resolve the Deadlock Issue to their mutual satisfaction during the
120-day period immediately following such date.

         13.4 Declaration of Deadlock Event.

                  (a) Under the circumstances described in Section 13.4(b), if a
Deadlock Issue is not resolved during the 120-day period described in Section
13.3 either Member may, within

                                       33
<PAGE>   39
30 days after the expiration of such 120-day period, give written notice to the
other Member declaring a Deadlock Event with respect to the Deadlock Issue.

                  (b) A Deadlock Event under Section 13.4(a) may be declared a
Deadlock Event only if the notice required by Section 13.4(a) is properly given.
Otherwise, no Deadlock Event may be declared, and the Members shall be subject
to Section 13.5.

         13.5 Failure to Declare Deadlock Event. If no Deadlock Event is, or
can be, declared under Section 13.4(a), the Deadlock Issue shall lapse, and
neither Member may thereafter give notice under Section 13.1 with respect to the
same issue until thirty (30) days has elapsed from the end of the 120-day period
specified in Section 13.3.

         13.6 Post-Declaration Time Period to Resolve Deadlock Event. The
Members shall attempt to resolve the Deadlock Event to their mutual satisfaction

resolved during the 30-day period described in Section 13.6, either Member may,
within 30 days immediately following that 30-day period give written notice to
the other Member exercising its right under Section 12.1(d) to dissolve the
Company.

         13.8 Buy-Sell Option. All of the terms and provisions of this Article
XIII are subject to the rights of the Members under Article XIV. Without
limiting the generality of the foregoing, any Member may exercise the rights set
forth in Article XIV notwithstanding the existence of a Deadlock Issue or a
Deadlock Event.

                                   ARTICLE XIV

                                BUY-SELL OPTION

         14.1 Buy-Sell Notice. At any time, either Member (the "Triggering
Member") may send a notice (the "Buy-Sell Notice") to the other Member (the
"Receiving Member"). The Buy-Sell Notice shall constitute a binding offer by the
Triggering Member to take either of the following actions, pursuant to this
Article XIV: (a) sell all of its Membership Interest to the Receiving Member, or
(b) purchase all of the Membership Interest of the Receiving Member, in either
case for the cash price per Sharing Ratio percentage (the "Purchase Price") set
forth in the Buy-Sell Notice.

         14.2 Actions by Receiving Member. No later than 60 days after the
giving of the Buy-Sell Notice to the Receiving Member, the Receiving Member
shall notify (the "Response Notice") the Triggering Member whether the Receiving
Member elects (a) to sell or (b) to purchase, in either case at the Purchase
Price. Failure to give the Response Notice within such 60-day period shall be
deemed to be an election to sell by the Receiving Member.

         14.3 Closing. The closing of the sale and purchase in accordance with
this Article XIV shall occur at the principal place of business of the Company
on the 60th day after (a) the

                                       34
<PAGE>   40
giving of the Response Notice or (b) after the date that the Receiving Member is
deemed to make an election to sell as set forth in Section 14.2 above, as the
case may be (or, if later, the fifth day after the receipt of all applicable
regulatory and governmental approvals to the purchase), unless the parties to
such closing agree upon a different place or date. At the closing, the following
shall occur:

                  (i) The Member purchasing the applicable Membership Interest
         (the "Purchaser") shall pay to the Member selling such Membership
         Interest (the "Seller") the Purchase Price.

                  (ii) The Seller shall transfer its Membership Interest to the
         Purchaser by instrument of assignment, bill of sale and such other
         instruments as shall be reasonably requested by the Purchaser, shall
         warrant to the Purchaser that the Membership Interest sold is free and
         clear of all legal and equitable claims of third parties and, if
         requested to do so by the Purchaser, shall provide an opinion of
         Seller's regular counsel stating that, in the opinion of such counsel,
         the instruments and agreements delivered to the Purchaser by Seller
         with respect to such sale are binding on the Seller.

         14.4 Failure to Close. If the Purchaser shall fail to complete its
acquisition of the Seller's Membership Interest pursuant to Section 14.3 for
reasons other than the breach by the Seller of any of its obligations imposed on
it thereunder, the Seller may elect (a) to purchase the Purchaser's Membership
Interest for a price equal to 90% of the Purchase Price that the Purchaser would
have received if, instead of being the Purchaser, it had been the Seller there
under, with the closing of the purchase and sale of such Membership Interest
pursuant to this Section 14.4 to take place within 90 days after notice is given
by the Seller to the Purchaser of its election to apply this Section 14.4, which
notice must be given within 60 days of such failure by Purchaser, or (b) to
cancel the Buy-Sell Notice or the Response Notice, as the case may be.
