registered agent named in the Certificate or such other office (which need not
be a place of business of the Company) as the Management Committee may designate
in the manner provided by Law. The registered agent shall be as stated in the

principal office of the Company shall be at such place as the Management
Committee may designate, and the Company shall maintain records there or such

order to carry out the intent of this Agreement.

      2.5   Term.  The period of existence of the Company (the "Term") commenced

      4.1   Business Plan. At such times as shall be specified by the Management
Committee, a business plan (the "Business Plan") of the Company will be prepared
annually by the Operations Committee of the Company and presented to the
Management Committee. The Business Plan will set out, among other things, the
projected operating and capital spending or investment budgets of the Company
and its subsidiaries for the calendar year and shall set forth income and
expense projections, Capital Contributions, planned distributions (including
distributions for taxes of the Members attributable to the income received by
the Members from the Company) and the projected activities of the Company and
its subsidiaries for such year.

      4.3   Technology; Research and Development.  The Company and United Solar
shall grant each other certain intellectual property rights pursuant to the
terms and conditions of a United Solar Systems Corp.- Bekaert ECD Solar Systems
LLC License Agreement. United Solar shall perform research and development for

Agreement.

      4.4   Services.  United Solar shall provide services to the Company
pursuant to terms and conditions of a Services Agreement.

      4.7   Accounting; Fiscal Year.  The accounting methods and systems

accounting principles, applied on a consistent basis, and those customarily

the independent public accountant for the Company. The Fiscal Year of the
Company shall be the calendar year.

      4.8   Insurance.  The Management Committee shall cause the Company to
maintain adequate amounts of insurance to cover the operations and insurable

effective to do so, procured and maintained by each individual Member or its
Affiliate in equal amounts of coverage. Each Member or its Affiliate shall also
procure and maintain professional liability insurance for its Representatives.

      4.9   Financing.  The financing of the Company shall be the responsibility
of the Company. If external borrowing with banks is not available on
commercially reasonable terms, Bekaert will arrange for additional financing on
an as needed basis up to Ten Million US Dollars (US$10,000,000) (reduced by
amounts guaranteed by Bekaert to Canon, Inc. under the Guaranty Agreement,
executed concurrently herewith, relating to FujiLease (whether paid or
contingent) (herein, the "FujiLease Guarantee")). If Bekaert's additional
financing of up to a maximum of Ten Million US Dollars (US$10,000,000) less the
FujiLease Guarantee is insufficient, the Management Committee will decide upon
alternative financing, and such decision will be considered a Material Action
under Section 6.2.5. Except as provided in Section 3.2, no Member shall have any
obligation to the Company or to the other Member to make additional Capital
Contributions or to guarantee the repayment of loans to the Company made by
third parties. Any required guarantee of a third-party loan shall be borne by
each Member in proportion to its respective Percentage Interest or as the
Management Committee otherwise decides, and such decision will be considered a
Material Action under Section 6.2.5.

thereafter that Member shall be an Assignee only unless such Membership Interest
shall be purchased by the Company and/or remaining Member. Each Member
acknowledges and agrees that such termination or purchase of a Membership
Interest upon the occurrence of any of the foregoing events is not unreasonable
under the circumstances existing as of the date hereof.

      5.5   Transactions With the Company.  Subject to any limitations set forth
in this Agreement and with the prior approval of the Management Committee, a
Member may lend money to and transact other business with the Company. Subject

all or any part of the Membership Interest; (ii) it is an "accredited investor"
as defined in Rule 501(a) of Regulation D promulgated by the Securities and
Exchange Commission; (iii) it understands that the Membership Interest has not

circumstances and that otherwise the Membership Interest must be held

                                   ARTICLE VI
                      MANAGEMENT AND CONTROL OF THE COMPANY
                      -------------------------------------

      6.1   Management by the Members.  The management of the Company is fully
vested in the Members, acting exclusively in their membership capacities. The
Company will not have "managers," as that term is used in the Act, it being
understood that the Representatives and Officers do not constitute "managers."

      6.2   Management Committee.  The Members shall act collectively through
meetings as a "committee of the whole," which is hereby named the "Management
Committee."  The Management

                                      6
<PAGE>


Committee shall consist of eight persons (each, a "Representative", and
collectively, the "Representatives"). 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:

            6.2.1  Representatives.
                   ---------------

                   (i)   Designation.  Prior to Unification, four of the
            Representatives shall be appointed by United Solar and four of the
            Representatives shall be appointed by Bekaert at each annual meeting
            of Members, or at any special meeting held for the purpose of
            appointing Representatives.  After Unification, the Representatives
            shall be appointed in proportion to the Member's Percentage
            Interest, which shall mean that the minority Member shall be
            entitled to appoint the number of Representatives equal to such
            Member's Percentage Interest multiplied by the total number of
            Representatives to be appointed (with fractions disregarded), and
            the majority Member shall be entitled to appoint the remaining
            Representatives.  Each Representative shall serve until the earlier
            of his resignation, removal by the Member who appointed him, death
            or disability, or until his successor is appointed.

                   (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 Member
            shall be entitled to rely upon such action without further inquiry
            or investigation as to the actual authority (or lack thereof) 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 OR ORGANIZATIONAL AFFAIR OF SUCH
            MEMBER), AND NOT TO THE COMPANY, ANY OTHER MEMBER OR REPRESENTATIVE,
            OR ANY OFFICER OF EMPLOYEE OF THE COMPANY.  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 OF INDIRECTLY, SUCH PERSON'S
            SERVICE ON THE MANAGEMENT COMMITTEE.

                   (iv)  Remuneration; Expenses.  No fee or other remuneration
            shall be payable by the Company to any Representative for his or her
            services as a

                                      7
<PAGE>

            Representative. Each Member shall bear all expenses incurred by its
            appointed Representatives in connection with attendance at
            Management Committee meetings, including, without limitation,
            transportation and lodging.

                   (v)   Attendance.  Each Member shall use all reasonable
            efforts to cause each of its Representatives to attend each meeting
            (including the means set forth in Section 6.2.8) of the Management
            Committee or appoint a proxy for such meetings.

            6.2.2  Chairman.  The Management Committee shall have a Chairman,
            who shall serve for a one-year term. Prior to Unification, one
            Representative representing Bekaert shall serve as Chairman. After
            Unification, the Chairman shall be elected by the Management
            Committee. Except as otherwise authorized by the Certificate, the
            duties of the Chairman shall be as set forth on Exhibit 6.3.

            6.2.3  Time and Place of Meetings.  The Management Committee shall
            meet quarterly, subject to more or less frequent meetings upon
            approval of a majority of the Representatives on the Management
            Committee. Notice of all such Management Committee meetings shall be
            provided by the Chairman to all Members at least ten (10) days prior
            to the date of the meeting, together with the 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 of
            the Members of the date and agenda for such meeting at least twenty
            (20) days prior to the date of the meeting. The notice periods for
            meetings (including special meetings) may be shortened by the
            Management Committee; provided, however, that in the event of an
            emergency or other circumstance reasonably requiring a meeting on
            less than five (5) business days' notice, the Chairman shall provide
            each Member with as much notice as practical prior to such meeting.
            All 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.

            6.2.4  Quorum.  Until January 1, 2010, in order for there to be a
            quorum for the transaction of any business at a meeting of the
            Management Committee there must be at least two (2) Representatives
            of each Member present. On and after January 1, 2010, in order for
            there to be a quorum for the transaction of any business at a
            meeting of the Management Committee there must be at least two
            Representatives present.  If at any meeting a quorum is not present
            at the commencement of business, the meeting shall stand adjourned
            until such time as a quorum is present, no later than the thirtieth
            (30th) business day thereafter, on which day the meeting shall
            reconvene at the same time and place with the same agenda.

            6.2.5  Voting.  Until January 1, 2010, any action of the Company
            shall be deemed approved if it is unanimously approved by the
            Management Committee, and otherwise shall be deemed not to be
            approved and will not be undertaken.  On and after January 1, 2010,
            any action of the Company shall be deemed approved if a majority of
            the Representatives voting on such matter vote in favor of such
            action, except with respect to any Material Action (as defined in
            Exhibit 6.2.5 hereto or as specifically provided for in Section 4.9
            of this Agreement) taken by the Management Committee, the unanimous
            approval of the Representatives voting on such matter shall be
            required; provided, however, that any matter considered a Material
            Action under this Section 6.2.5 shall be considered a general action
            governed by the approval of a majority of the Representatives if a
            Member's Percentage Interest in the Company is less than
            thirty-three percent (33%), but, however, if such Member's
            Percentage Interest in the Company is less than thirty-three percent
            (33%) but greater than nineteen percent (19%) the matters identified
            as (b)(ii) and (b)(vi)(excluding issuance of debt securities) of
            Exhibit 6.2.5 shall still be considered a Material Action under this
            Section 6.2.5.

            6.2.6  Deadlock of the Management Committee.  If the Management
            Committee is unable to act upon any proposal submitted to it for
            action at a meeting of the Management Committee, because of lack of
            quorum or the required vote (as provided in this Agreement), and
            either Member gives notice in writing to the other Member and to the
            Company of its decision to cause the commencement of the procedure
            set forth below, the Management Committee will be deemed to be in
            "Deadlock." The Company shall continue to operate during any period
            of Deadlock of the Management Committee, and in no event shall the
            Deadlock interfere with the rights of the Representatives and
            Officers of the Company to operate the Company. Deadlock shall be
            resolved in the following manner:

               (a)   Upon the occurrence of Deadlock, each Member shall
                     designate one (1) of its Representatives on the Management
                     Committee (the "Designated Representative") to meet and
                     discuss the Deadlock in good faith. The Designated
                     Representatives shall have thirty (30) days from the
                     occurrence of Deadlock to reach resolution of the proposal
                     in Deadlock.

               (b)   If the Designated Representatives are unable to resolve
                     the Deadlock within the thirty (30) day period referred to
                     in subsection (a) above, then each Member shall cause the
                     Deadlock to be referred to a director or senior officer of
                     such Member not involved in the business of the Company
                     ("Disinterested Officer") to meet and discuss the Deadlock
                     in good faith. The Disinterested Officers shall have
                     thirty (30) days from the end of the period referred to in
                     subsection (a) above to reach resolution of the proposal
                     in Deadlock.

               (c)   If the Disinterested Officers are unable to resolve the
                     Deadlock within the thirty (30) day period referred to in
                     subsection (b) above, either Member may elect to submit the
                     Deadlock proposal for settlement by mediation ("Demanding
                     Member").  The demand for mediation must be submitted by


                                      9
<PAGE>

                     the Demanding Member within thirty (30) days of the end of
                     the period referred to in subsection (b) above (the
                     "Demand").  The Members may mutually agree upon a mediator
                     (who must be experienced in the area of the proposal that
                     is in Deadlock) and the rules which will apply to the
                     mediation. If the Members are unable to agree upon a
                     mediator or the rules to apply to the mediation, then the
                     parties will use the then current applicable mediation
                     rules of the CPR Institute for Dispute Resolution to
                     choose the mediator or set rules of the mediation.  Any and
                     all necessary relevant mediation will be held in Chicago,
                     Illinois.  The Demand will identify the proposal that is
                     in Deadlock and will state the issue proposed to be
                     resolved in mediation and the resolution sought.  If after
                     five (5) days of mediation the Deadlock is not resolved,
                     or if the mediator declares an impasse prior to the end of
                     the five (5) day period, then if the Members do not
                     mutually agree to continue mediation, mediation shall
                     terminate.  The resolution of the Deadlock by mediation
                     shall not be binding on either Member unless the Members
                     mutually agree to accept the resolution of the Deadlock
                     achieved through the mediation.

               (d)   If the Deadlock is not resolved through mediation as set
                     forth in subsection (c) above, either Member may within
                     thirty (30) days of the termination of mediation submit the
                     Deadlock proposal to arbitration in accordance with the
                     then-current rules of the American Arbitration Association
                     ("AAA").  The arbitration, including the rendering of the
                     the award, shall take place in Chicago, Illinois.  The
                     governing procedural and substantive law of the arbitration
                     shall be the internal laws of the State of Delaware,
                     without regard to conflicts of law principles.  The
                     arbitration shall be conducted by one (1) arbitrator
                     appointed by the AAA and who shall be experienced in the
                     area of the proposal that is in Deadlock.  Each Member
                     shall submit to the arbitrator a proposal to resolve the
                     matter in Deadlock (the "Substantive Proposal").  In
                     addition to the Substantive Proposal, each Member may
                     submit to the arbitrator a proposal of an exit method for
                     such Member if the arbitrator does not find in favor of
                     that Member's Substantive Proposal (the "Exit Proposal").
                     With regard to the Substantive Proposals, the arbitrator
                     shall rule only upon the Substantive Proposals submitted by
                     the Members, and must choose between the positions taken
                     on the matter by each Member (as opposed to adopting a
                     compromise position) and report his conclusion to the
                     Members as promptly as possible after submission of the
                     Substantive Proposals.  The decision of the arbitrator
                     as to the Substantive Proposals shall be nonbinding on the
                     Members.  With regard to the Exit Proposals, the arbitrator
                     may choose either the Exit Proposal submitted by the Member
                     whose Substantive Proposal is rejected by the arbitrator or
                     an amended version of such Exit Proposal (such Exit
                     Proposal, as possibly amended, the "Exit Solution").  In
                     determining the Exit Solution of a Member the Members agree
                     that the arbitrator must consider the fair market value of
                     the Company and the reasonableness of the Member's
                     Substantive and Exit Proposals.  The

                                      10
<PAGE>


                     Members further agree that the arbitrator may consider the
                     respective financial condition of the Members in
                     determining whether the consideration for the sale of such
                     Member's Membership Interest shall be paid in cash and/or
                     in kind, and whether such payment shall be effected at the
                     closing of the sale and/or shall be deferred.  The
                     arbitrator shall report his decision regarding the Exit
                     Solution at the same time as he reports his conclusion
                     regarding the Substantive Proposals.  Within thirty (30)
                     days of the date of written notice from the arbitrator
                     to the Members and to the Company, the Member whose
                     Substantive Proposal was rejected by the arbitrator must
                     elect to accept the Exit Solution.  If such Member does not
                     accept the Exit Solution such Member will remain a member
                     of the Company.  The decision of the arbitrator as to the
                     Exit Solution shall be final and binding on both Members if
                     the Member whose Substantive Proposal is rejected chooses
                     to accept the Exit Solution.

            6.2.7  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 the Representatives that could have taken the action
            at a meeting of the Management Committee at which all of the
            Representatives entitled to vote on the action were represented
            and voted.

            6.2.8  Meeting by Telephone. The Representatives 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 Representative 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.

            6.2.9  Advisors.  The Representatives may be accompanied by a
            reasonable number of advisors, who may participate in the meetings,
            but who shall not vote.

            6.2.10  Proxy.  Any Representative may, by instrument in writing
            signed by such Representative, which may be by letter, or telefax,
            appoint a person, who may or may not be a Representative, to act as
            his proxy at any meeting or for any stated duration of time. Any
            person so appointed shall, for the duration of his appointment,
            unless otherwise provided in such proxy, have all the rights of the
            appointer (including the right to one vote) and shall be counted in
            determining whether a quorum has been constituted.

      6.3   Officers. The individuals holding the offices of Chairman, Chief
Executive Officer and President of the Company shall be as set forth in Exhibit
6.3. The Management Committee may also appoint any other officers that the
Management Committee deems necessary to carry on the day-to-day operations of
the Company. All such officers shall be appointed by and serve at the

            6.4.1  Operations Committee. The Management Committee shall
            appoint an Operations Committee consisting of officers of the
            Company (the "Operations Committee"). The Operations Committee

            of the Company, together with such other duties as the Management
            Committee may determine. Prior to Unification, one-half of the
            members of the Operations Committee shall be appointed by United
            Solar and one-half by Bekaert. After Unification, the members of
            the Operations Committee shall be appointed in proportion to the
            Member's Percentage Interest.

            6.4.2  Subcommittees.  The Management Committee may create such

            responsibility, and rescind any such delegations, as it may deem
            appropriate.

            described in Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5), or
            (6), items of Company income and gain shall be specially allocated
            to each such Member in an amount and manner sufficient to eliminate,
            to the extent required by the Regulations, the Adjusted Capital
            Account Deficit of such Member as quickly as possible, provided that
            an allocation pursuant to this Section 7.2.1 shall be made if and
            only to the extent that such Member would have an Adjusted Capital
            Account Deficit after all other allocations provided for in this
            Article VII have been tentatively made as if this Section 7.2.1
            were not in the Agreement.

            deficit Capital Account at the end of any Company fiscal year that
            is in excess of the sum of (i) the amount such Member is obligated

<PAGE>

            2(g)(1) and 1.704-2(i)(5), each such Member shall be specially
            allocated items of Company income and gain in the amount of such
            excess as quickly as possible, provided that an allocation pursuant
            to this Section 7.2.2 shall be made only if and to the extent that
            such Member would have a deficit Capital Account in excess of such
            sum after all other allocations provided for in this Article VII
            have been tentatively made as if Section 7.2.1 and this Section
            7.2.2 were not in the Agreement.

            7.2.3  Company Minimum Gain Chargeback.  Except as otherwise
            provided in Section 1.704-2(f) of the Regulations, and
            notwithstanding any other provision of this Section 7.2, if there
            is a net decrease in Company Minimum Gain during any fiscal year,
            each Member shall be specially allocated items of Company income
            and gain for such fiscal year (and, if necessary, subsequent fiscal
            years) in an amount equal to such Member's share of the net decrease
            in Company Minimum Gain, determined in accordance with Regulations
            Section 1.704-2(g).  Allocations pursuant to the previous sentence
            shall be made in proportion to the respective amounts required to
            be allocated to each Member pursuant thereto. The items to be so
            allocated shall be determined in accordance with Sections 1.704-2(f)
            (6) and 1.704-2(j)(2) of the Regulations. This Section 7.2.3 is
            intended to comply with the minimum gain chargeback requirement in
            Section 1.704-2(f) of the Regulations and shall be interpreted

            is a net decrease in Member Minimum Gain attributable to a Member
            Nonrecourse Debt during any fiscal year, each Member who has a
            share of the Member Minimum Gain attributable to such Member
            Nonrecourse Debt, determined in accordance with Section 1.704-2(i)
            (5) of the Regulations, shall be specially allocated items of
            Company income and gain for such fiscal year (and, if necessary,
            subsequent fiscal years) in an amount equal to such Member's share
            of the net decrease in Member Minimum Gain attributable to such
            Member Nonrecourse Debt, determined in accordance with Regulations
            Section 1.704-2(i)(4). Allocations pursuant to the previous sentence
            shall be made in proportion to the respective amounts required to be
            allocated to each Member pursuant thereto. The items to be so
            allocated shall be determined in accordance with Sections 1.704-2(i)
            (4) and 1.704-2(j)(2) of the Regulations. This Section 7.2.4 is
            intended to comply with the minimum gain chargeback requirement in
            Section 1.704-2(i)(4) of the Regulations and shall be interpreted

            Deductions for any fiscal year shall be specially allocated to the
            Member who bears the economic risk of loss with respect to the
            Member Nonrecourse Debt to which such Member Nonrecourse Deductions
            are attributable, in accordance with Regulations Section 1.704.

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

            7.2.8  Curative Allocations.  The "Regulatory Allocations" consist
            of the allocations pursuant to Sections 7.2.1 through 7.2.6 hereof.
            Notwithstanding any other provision of this Agreement, the
            Regulatory Allocations shall be taken into account in allocating
            items of income, gain loss and deduction among the Members so that,
            to the extent possible, the net amount of such allocations of other
            items and the Regulatory Allocations to the Members shall be equal
            to the net amount that would have been allocated to the Members if
            the Regulatory Allocations had not occurred.

      7.3   Tax Allocations:  Code Section 704(c).
            -------------------------------------

            7.3.1  In accordance with Code Section 704(c) and the Regulations
            thereunder, income, gain, loss, and deduction with respect to any
            property contributed to the capital of the Company shall, solely for
            tax purposes, be allocated among the Members so as to take account
            of any difference (the "Section 704(c) Amount") between the adjusted
            basis of such property to the Company for federal income tax
            purposes and its initial Gross Asset Value. Schedule 7.3.1 attached
            to this Agreement sets forth the Section 704(c) Amount with respect
            to the United Solar Contributed Assets as of the date of their
            contribution to the Company by the Members.

            7.3.2  In the event the Gross Asset Value of any Company asset is
            adjusted pursuant to Member Nonrecourse Debt hereof, subsequent
            allocations of income, gain, loss and deduction with respect to such
            asset shall take account of any variation between the adjusted basis
            of such asset for federal income tax purposes and its Gross Asset
            Value in the same manner as under Code Section 704(c) and the
            Regulations thereunder.

            7.3.3  The Company shall elect the traditional method as set forth
            in Regulations Section 1.704-3(b) for purposes of making allocations
            under Code Section 704(c).

            7.3.4 Any other elections or other decisions relating to such
            allocations shall be made by the Management Committee in any manner
            that reasonably reflects the purpose and intention of this
            Agreement.  Allocations pursuant to this Section 7.3 are solely for
            purposes of federal, state, and local taxes and shall not affect,
            or in any way be taken into account in computing, any Member's
            Capital Account or share of Net Profits, Net Losses, other items,
            or distributions pursuant to any provision of this Agreement.

      7.4   Net Profits and Losses and Distributions in Respect of a Transferred
Interest. If any Economic Interest is transferred, or is increased or decreased
by reason of the admission of a new Member or otherwise, during any Fiscal Year
of the Company, Net Profit or Net Loss for such Fiscal Year shall be assigned
pro rata to each day in the particular period of such Fiscal Year to which such
item is attributable (i.e., the day on or during which it is accrued or
otherwise incurred) and the amount of each such item so assigned to any such
day shall be allocated to the Member or Assignee based upon his or her
respective Economic Interest at the close of such day.

      7.5   Distribution of Assets by the Company. Subject to applicable law and
any limitations contained elsewhere in this Agreement, the Management Committee
may elect from time to time to distribute Distributable Cash to the Members
(provided, however, except for the tax distributions described below, that no
distributions will be made prior to Unification), which distributions shall be
in the following order of priority:

      (a)   To the Members in proportion to their unreturned Capital
      Contributions until each Member has recovered his or her Capital
      Contributions; and

      (b)   To the Members in proportion to their Percentage Interests.

            Notwithstanding any other provision of this Agreement to the
contrary, the Company shall make pro-rata distributions to the Members for the
payment of taxes in accordance with the following:

      (y)   the amount distributable with respect to any year shall be equal to
      the aggregate amount of Federal, state and local income taxes payable by
      the Members with respect to the income items of the Company allocated to
      the Members, assuming, for purposes of determining the amount of such
      distribution, that each Member will be taxed on the amounts set forth in
      its respective K-1 at the highest marginal Federal income tax rate
      applicable to corporations in effect for each taxable year, and at the
      highest marginal corporate state and local franchise/income tax rates
      applicable to any Member for each such taxable year; and

      (z)   such distributions shall be payable at such time or times and
      in such amounts as will enable the Members, or any one of them, to avoid
      penalties and interest otherwise payable on account of the failure to
      pay a sufficient amount of estimated taxes as required by law.

All such distributions shall be made only to the Persons who, according to the
books and records of the Company, are the holders of record of the Economic
Interests in respect of which such distributions are made on the actual date of
distribution. Neither the Company nor any Representative shall incur any
liability for making distributions in accordance with this Section 7.5.

      7.6   Form of Distribution.  A Member, regardless of the nature of the
Member's Capital Contribution, has no right to demand and receive any
distribution from the Company in any form

                                      15

<PAGE>

other than money. No Member may be compelled to accept from the Company a
distribution of any asset in kind in lieu of a proportionate distribution of
money being made to other Members. Except upon a dissolution and winding up of
the Company, no Member may be compelled to accept a distribution of any asset
in kind.

      7.7   Restriction on Distributions
            ----------------------------

            7.7.1   No distribution shall be made if, after giving effect to
            the distribution:

               (a)  The Company would not be able to pay its debts as they
                    become due in the usual course of business; or

               (b)  The Company's total assets would be less than the sum
                    of its total liabilities plus, unless this Agreement
                    provides otherwise, the amount that would be needed, if
                    the Company were to be dissolved at the time of the
                    distribution, to satisfy the preferential rights of other
                    Members, if any, upon dissolution that are superior to the
                    rights of the Member receiving the distribution.

            7.7.2   The Management Committee may base a determination that a
            distribution is not prohibited on any of the following:

               (a)  Financial statements prepared in accordance with United
                    States generally accepted accounting principles;

               (b)  A fair valuation;

               (c)  Any other method that is reasonable in the circumstances.

            Except as provided in Section 18-607(b) of the Act, the effect of a
            distribution is measured as of the date the distribution is
            authorized if the payment occurs within one hundred twenty (120)
            days after the date of authorization, or the date payment is made
            if it occurs more than one hundred twenty (120) days after the date
            of authorization.

            7.7.3   A Member or Representative who votes for a distribution in
            violation of this Agreement or the Act is personally liable to the
            Company for the amount of the distribution that exceeds what could
            have been distributed without violating this Agreement or the Act
            if it is established that the Member or Representative did not act
            in compliance with Section 7.7.2. Any Member or Representative who
            is so liable shall be entitled to compel contribution from (i) each
            other Member or Representative who also is so liable and (ii) each
            Member for the amount the Member received with knowledge of facts
            indicating that the distribution was made in violation of this
            Agreement or the Act.

      7.8   Return of Distributions. Members and Assignees who receive
distributions made in violation of the Act or this Agreement shall return such
distributions to the Company. Except for

                                      16
<PAGE>

those distributions made in violation of the Act or this Agreement, no Member
or Assignee shall be obligated to return any distribution to the Company or pay
the amount of any distribution for the account of the Company or to any creditor
of the Company. The amount of any distribution returned to the Company by a
Member or Assignee or paid by a Member or Assignee for the account of the
Company or to a creditor of the Company shall be added to the account or
accounts from which it was subtracted when it was distributed to the Member or
Assignee.

      7.9   Obligations of Members to Report Allocations. The Members are aware
of the income tax consequences of the allocations made by this Article VII and
hereby agree to be bound by the provisions of this Article VII in reporting
their shares of Company income and loss for income tax purposes.

                                  ARTICLE VIII
                 TRANSFER AND ASSIGNMENT OF MEMBERSHIP INTERESTS
                 -----------------------------------------------

      8.1   Transfer and Assignment of Membership Interests.  Except with the
prior written consent of the other Member, which consent may be given or
withheld, conditioned or delayed (as allowed by this Agreement or the Act), as
the other Member may determine in its sole and absolute discretion, or as
provided in Section 8.3 or Section 8.5, no Member shall be entitled to transfer,
assign, convey, sell, encumber or in any way alienate all or any part of its
Membership Interest (collectively, "transfer"). After the consummation of any
transfer of a Membership Interest, the Membership Interest so transferred shall
continue to be subject to the terms and provisions of this Agreement and any
further transfers shall be required to comply with all the terms and provisions
of this Agreement. No Member may transfer less than all of its Membership
Interest or Economic Interest.

      8.2   Further Restrictions on Transfer of Interests.  In addition to other
restrictions found in this Agreement, no Member shall transfer its Membership
Interest (i) without compliance with all federal and state securities laws; (ii)
if such transfer would cause an acceleration of or be deemed a default under any
financing obligation of the Company; or (iii) except as provided in Section 8.3,
if the Membership Interest to be transferred, when added to the total of all
other Membership Interests transferred in the preceding twelve (12) consecutive
months prior thereto, would cause the termination of the Company under the Code,
as determined by the Management Committee.

      8.3   Permitted Transfers.  A Member or its Affiliate may transfer all,
but not less than all, of its Membership Interest or Economic Interest to its
Affiliate, subject to compliance with Section 8.2(ii), without the prior written
consent of the Members or the Management Committee; provided, however, the
transferee of such Membership Interest shall (i) become a Member under this
Agreement, (ii) assume all rights and obligations of the transferring Member,
(iii) execute an instrument satisfactory to the Management Committee accepting
and adopting the terms and provisions of this Agreement, and (iv) pay any
reasonable expenses in connection with its admission as a new Member. If after
a transfer to an Affiliate pursuant to this Section 8.3, an Affiliate will no
longer be an Affiliate of the original Member, such Affiliate must sell, assign
and transfer all the Membership Interest back to the original Member and the
original Member must purchase and accept such Membership Interest at least
fifteen (15) days prior to its change in Affiliate status.

                                      17
<PAGE>

      8.4   No Effect to Transfers in Violation of Agreement.  No purported
transfer of Membership Interest in violation of the provisions of this Agreement
shall be valid and the Company shall not transfer any of such Membership
Interest on its books, nor shall the purported transferee of such Membership
Interest be entitled to vote, nor shall any distributions be paid thereon,
during the period of any such violation. The provisions of this Section 8.4
shall be in addition to and not in lieu of any other remedies, legal or
equitable, available to enforce this Agreement. Except as set forth in Section
8.3, each Member hereby undertakes not to make any transfer of its Membership
Interest (i) unless the Company has received an opinion of counsel in form and
substance satisfactory to the Company, to the effect that such transfer will not
be in violation of the Securities Act, and any applicable state securities laws
and (ii) except to a person who has executed a counterpart hereof.

      8.5   Right of First Refusal.  Except as provided in Section 8.3 with
respect to permitted transfers to an Affiliate, neither Member may transfer its
Membership Interest without the prior written consent of the other Member, which
consent may be given or withheld, conditioned or delayed (as allowed by this
Agreement or the Act) as such other Member may determine in its sole and
absolute discretion. From and after two (2) years from the effective date of
this Agreement, a Member may transfer its Membership Interest provided that each
time a Member proposes to transfer its Membership Interest (or is required by
operation of law or other involuntary transfer to do so) other than pursuant to
Section 8.3, such Member shall first offer such Membership Interest to the
non-transferring Member, and then to the Company, in accordance with the
following provisions:

            8.5.1  Such Member shall deliver a written notice to the other
            Member and the Company stating (i) such Member's bona fide intention
            to transfer its Membership Interest, (ii) the name and address of
            the proposed transferee, and (iii) the purchase price and terms of
            payment for which the Member proposes to transfer its Membership
            Interest.

            8.5.2  The non-transferring Member shall have the first right to
            purchase such Membership Interest upon the price and terms of
            payment designated in the notice provided in Section 8.5.1, by
            notifying the transferring Member and the Company in writing, within
            thirty (30) days after receipt of the notice provided in Section
            8.5.1, of its desire to purchase such Membership Interest. Upon
            receipt of such written notice, the transferring Member shall sell
            its Membership Interest to the other Member upon such price and
            terms. If the notice provided in Section 8.5.1 provides for the
            payment of non-cash consideration, the non-transferring Member may
            elect to pay the consideration in cash equal to the fair market
            value of the non-cash consideration offered, as determined in
            accordance with Section 9.3.

            8.5.3 The failure of the non-transferring Member to submit a
            notice within the period set forth in Section 8.5.2 shall constitute
            an election on the part of the non-transferring Member not to
            purchase such Membership Interest, in which case, the Management
            Committee shall make the determination, within sixty (60) days of
            the notice provided in Section 8.5.1, whether the Company will
            purchase such Membership Interest, by notice in writing to the
            transferring Member; provided, however the Representatives of the
            transferring Member shall not participate in or have a vote in the
            decision of the Management Committee to purchase such Membership
            Interest, and the decision of the Representatives of

                                      18
<PAGE>

            the non-transferring Member shall be deemed the decision of the
            Management Committee with respect to such purchase. The Management
            Committee shall notify the transferring Member of its intention to
            so purchase, and the transferring Member shall sell its Membership
            Interest to the Company upon the price and terms of payment
            designated in the notice provided in Section 8.5.1. If the notice
            provided in Section 8.5.1 provides for the payment of non-cash
            consideration, the Company may elect to pay the consideration in
            cash equal to the fair market value of the non-cash consideration
            offered, as determined in accordance with Section 9.3.

            8.5.4   If neither the non-transferring Member nor the Company
            elects to purchase the transferring Member's Membership Interest,
            then the transferring Member may transfer its Membership Interest
            to the proposed transferee, provided such transfer (a) is completed
            within thirty (30) days after the expiration of the non-transferring
            Member's or the Company's right to purchase such Membership
            Interest, as the case may be, (b) is made on terms no less favorable
            to the transferring Member than as designated in the notice, and
            (c) complies with the requirements of Section 8.2. If such
            Membership Interest is transferred, the transferee of such
            Membership Interest shall (i) become a Member under this Agreement,
            (ii) assume all rights and obligations of the transferring Member,
            (iii) execute an instrument satisfactory to the Management Committee
            accepting and adopting the terms and provisions of this Agreement,
            and (iv) pay any reasonable expenses in connection with its
            admission as a new Member. If such Membership Interest is not so
            transferred, the transferring Member must give notice in accordance
            with this Section prior to any other or subsequent transfer of such
            Membership Interest.

                                   ARTICLE IX
                                 BUY OUT OPTION
                                 --------------

      9.1   Buyout Events.   This Article 9 shall apply to any of the following
events (each a "Buyout Event"):

      (a)   a Member shall dissolve or (i) makes a general assignment for
      the benefit of creditors; (ii) files a voluntary bankruptcy petition;
      (iii) becomes the subject of an order for relief or is declared
      insolvent in any federal or state bankruptcy or insolvency proceedings;
      (iv) files a petition or answer seeking for such Member a
      reorganization, arrangement, composition, readjustment, liquidation,
      dissolution or similar relief under any law; (v) files an answer or
      other pleading admitting or failing to contest the material allegations
      of a petition filed against such person in a proceeding of the type
      described in subclauses (i) through (iv) of this clause (a); or (vi)
      seeks, consents to or acquiesces in the appointment of a trustee,
      receiver or liquidator of such Member or of all or any substantial part
      of such Member's properties;

      (b)   there shall occur a Change In Control; or

      (c)   a Member shall commit a Buyout Default.

                                      19
<PAGE>

It is understood and agreed by the Members that the application of the
provisions of this Article IX in the event of a Buyout Event shall be in
addition to, and not in lieu of, any other remedies (whether at law or in
equity) which a Member may have against the other Member (or a party related to
such Member) upon the occurrence of a Buyout Event. In each case, the Member
with respect to whom a Buyout Event has occurred is referred to herein as the
"Affected Member."

      9.2   Procedure.  Following the occurrence of a Buyout Event, the Affected
Member shall promptly give notice thereof to the Company and the other Member
(the "Purchasing Member"). The Affected Member shall have sixty (60) days from
the date of the occurrence of the Buyout Event to cure such Buyout Event (the
"Cure Period"). If the Affected Member has not cured the Buyout Event within the
Cure Period, the Purchasing Member shall have the option to acquire the
Membership Interest of the Affected Member by notifying the Affected Member and
the Company in writing, within thirty (30) days after the Cure Period of the
Buyout Event of its desire to purchase the Affected Member's Membership Interest
(either from the Affected Member or otherwise).

      9.3   Purchase Price.  The purchase price for a Membership Interest being
purchased pursuant to Section 9.2 (the "Purchase Price") shall be determined in
the following manner. The Affected Member and the Purchasing Member shall
attempt to agree upon the fair market value of the applicable Membership
Interest. If those Members do not reach such agreement on or before the
thirtieth (30th) day following the exercise of the option, any such Member, by
notice to the others, may require the determination of fair market value (such
fair market value shall be measured at the time the Buyout Event occurred) to be
made by the Arbitrator pursuant to Article 1 of Appendix C. Following the
determination of fair market value by agreement or arbitration (the "Fair Market
Value"), the Purchase Price shall be determined and paid in accordance with the
following chart and procedures:

Buyout                       Closing     Interest                    Payment
Event                        Percent     Rate            Term        Frequency
-------------------          -------     -----------     -------     ---------
Set forth in 9.1(a)            20%       Buyout Rate     4 years     quarterly
Set forth in 9.1(b)            20%       Buyout Rate     4 years     quarterly
Set forth in 9.1(c)            20%       Buyout Rate     4 years     quarterly

The following provisions shall apply to the determination and payment of the
Purchase Price:

      (a)   the Purchase Price shall be the Fair Market Value less the
      amount of all monetary damages suffered by the Company and the
      Purchasing Member as a result of such Buyout Event;

      (b)   at the closing of the purchase of the Affected Member's
      Membership Interest (the "Buyout Closing"), the Purchasing Member shall
      pay the Affected Member a portion of the Purchase Price equal to the
      Purchase Price multiplied by the percentage shown for such Buyout Event
      in the "Closing Percent" column;

      (c)   if the applicable Closing Percent is less than 100%, then the
      remainder of the Purchase Price (the "Deferred Amount"), shall accrue
      interest from the date of the Buyout

                                      20
<PAGE>

      Closing at the rate per annum shown for such Buyout Event in the
      "Interest Rate" column (not to exceed the maximum rate permitted by
      Law); and

      (d)   the Deferred Amount, together with accrued interest (at the
      interest rate shown for such Buyout Event in the "Interest Rate" column)
      thereon, shall be paid by the Purchasing Member in equal cash
      installments over a four (4) year term in quarterly payments, with the
      amount of the cash installments being calculated to amortize fully the
      Deferred Amount (and accrued interest thereon) over the applicable term.
      The installments shall be paid on the first day of January, April, July
      and October during the four year term, with appropriate adjustments to
      the first or last payments to reflect a closing that does not occur on
      the first day of a quarter. The payment to be made to the Affected
      Member pursuant to this Section shall be in complete liquidation and
      satisfaction of all the rights and interest of the Affected Member in
      and in respect of the Company, including any Membership Interest, any
      rights in specific Company property, and any rights against the Company
      and (insofar as the affairs of the Company are concerned) against the
      Purchasing Member, and constitutes a compromise to which all Members
      have agreed pursuant to Section 18-502(b) of the Act.

      9.4   Buyout Closing.  If an option to purchase is exercised in accordance
with Section 9.2, the Buyout Closing shall occur on the thirtieth (30th) day
after the determination of the Fair Market Value pursuant to Section 9.3 (or, if
later, the fifth business day after the receipt of all applicable consents and
approvals of all Governmental Authorities to the purchase); provided, however,
that the Purchasing Member shall deliver to the Affected Member (a) the portion
of the Purchase Price required by Section 9.3 to be paid at the closing, in
immediately available funds, and (b) one or more unsecured promissory notes
reflecting the payment terms established in Section 9.3 for the Deferred Amount.

      9.5   Terminated Member.  Upon the occurrence of a closing under Section
9.4, the following provisions shall apply to the Affected Member (now a
"Terminated Member"):

      (a)   The Terminated Member ceases to be a Member immediately upon the
      occurrence of the closing.

      (b)   As the Terminated Member is no longer a Member, it will no
      longer be entitled to receive any distributions (including liquidating
      distributions) or allocations from the Company, and neither it nor its
      Representatives shall be entitled to exercise any voting or consent
      rights or to receive any further information (or access to information)
      from the Company.

      (c)   The Terminated Member must pay in full to the Company all
      amounts owed to the Company by such Member.

      (d)   The Terminated Member shall remain obligated for all liabilities it
      may have under this Agreement or otherwise with respect to the Company
      that accrue prior to the closing.

                                      21
<PAGE>

      (e)   The Percentage Interest of the Terminated Member shall be allocated
      to the Purchasing Member.

      10.1  Dissolution
            -----------

            10.1.1  Subject to Section 10.1.2, the Company shall dissolve and
            its affairs shall be wound up on the first to occur of the following
            events (each a "Dissolution Event"):

               (a)  the unanimous consent of the Members;

               (b)  the dissolution or Bankruptcy of a Member; or

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

               (d)  dissolution under Section 11.1(b)(iii) of the Foundation
                    Agreement.

            10.1.2  If a Dissolution Event described in Section 10.1.1(b)
            shall occur, the Company shall not be dissolved, and the business
            of the Company shall be continued if the remaining Member elects
            within ninety (90) days of the occurrence of such Dissolution Event
            to continue (such agreement is referred to herein as a "Continuation
            Election").

      10.2  Winding-Up and Termination.
            --------------------------

            10.2.1  Liquidation.  On the occurrence of a Dissolution Event,
            unless a Continuation Election is made, the Management Committee
            shall act as liquidator; provided, however, that if a Dissolution
            Event described in Section 10.1.1(b) has occurred to a Member, then
            the liquidator shall be selected by the majority of the Members
            that have not suffered a Dissolution Event. The liquidator may sell
            any or all Company property and 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:

               (a)  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;

                                      22
<PAGE>

               (b)  the liquidator shall pay, satisfy or discharge from
               Company funds all of the debts, liabilities and obligations of
               the Company 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

               (c)  all remaining assets of the Company shall be distributed
               to the Members, in accordance with their positive Capital Account
               balances; provided, however, the Capital Accounts of the Members
               shall first be adjusted to reflect the manner in which any
               unrealized income, gain, loss and deduction inherent in the
               Company's property, which has not previously been reflected in
               the Members' Capital Accounts, would be allocated among the
               Members if there were a taxable disposition of such property at
               fair market value on the date of distribution.

            10.2.2  Complete Distribution.  The distribution of cash or property
            to a Member in accordance with the provisions of this Section 10.2
            constitutes a complete return to the Member of its Capital
            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.

      10.3   Deficit Capital Accounts. No Member will 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 the Member's Capital Account.

      10.4   Certificate of Cancellation. On completion of the distribution of
Company assets as provided herein, the Members (or such other Person or Persons
as the Act may require or permit) shall file a certificate of cancellation with
the Secretary of State of Delaware, cancel any other filings made pursuant to
Section 2.7, and take such other actions as may be necessary to terminate the
existence of the Company. Upon the filing of such certificate of cancellation,
the existence of the Company shall terminate (and the Term shall end), except as
may be otherwise provided by the Act or other applicable Law.

         of the Person as Member, Representative or Assignee, to:

         Member.

cause the income tax returns for the Company to be finally prepared and timely

of the Company in one or more separate accounts in the name of the Company, and
shall not permit the funds of the Company to be commingled in any fashion with

Committee.

      11.5   Accounting Decisions and Reliance on Others. All decisions as to
accounting matters, except as otherwise specifically set forth herein, shall be

advice of its accountants as to whether such decisions are in accordance with

      11.6   Tax Matters for the Company. The Management Committee shall from
time to time cause the Company to make such tax elections as it deems to be in

who was or is a party or is threatened to be made a party to any threatened,

such liability under the provisions of Section 12.1 or under applicable law.

                                  -------------

      13.1   Nondisclosure. Except as provided in separate written agreements
between a Member and the Company, each Member agrees that it shall not, during
the time it is a member of the Company and for a period of three (3) years
thereafter, disclose, divulge, discuss, copy or otherwise use or suffer to be
used in any manner, the contents of the Foundation Agreement and the Transaction
Agreements, the customer lists, marketing plans and strategies, pricing and
other methods used by the Company or any subsidiary of the Company in its
business, or trade secrets or proprietary information of the entities, it being
acknowledged by each Member that all such information regarding such businesses
of such entities compiled or obtained by, or furnished to, such Member while it
shall have been a member of the Company is confidential information and the
Company's exclusive property. The foregoing obligations shall not apply to any
date, know-how, or information which (i) is or becomes available from another
source such as, without limitation, a public source, other than as a consequence
of breach of the obligations herein set forth, (ii) has been or is independently
developed by the Member without reliance on the confidential information, or
(iii) is required to be disclosed under Law.

      13.2   Modifications; Equitable Relief. Each of the Member's expressly
agrees that if any claim is made that if the covenants set forth in Section 13.1
above is invalid or unenforceable, due to the duration or geographic area
thereof, and/or otherwise, the covenant shall not thereby be rendered invalid or
unenforceable, but it shall instead be modified to the maximum duration, maximum
geographic area, and/or otherwise as a court of competent jurisdiction examining
the covenant shall find to be reasonable and legally enforceable. Each Member
expressly agrees and understands that the remedy at law for any breach by it of
any of the provisions of Section 13.1 will be inadequate and that the damages
flowing from such breach are not readily susceptible to being measured in
monetary terms. Accordingly, it is acknowledged that upon adequate proof of a
parties' violation of any legally enforceable provision of Section 13.1 above,
the Company or either Member shall be entitled to immediate injunctive relief
and may obtain a temporary order restraining any threatened or further breach.
Nothing contained herein shall be deemed to limit the Members' or the Company's
remedies at law or in equity which may be pursued or availed of by them for any
breach by a party of the provisions of Section 13.1.

                                   ARTICLE XIV
