            (b) The Warrant Rights of each Initial Member (x) shall be exercised
      by an Initial Member (through a binding commitment to purchase equity
      securities in the Company IPO) prior to distribution of the preliminary

      Initial Member if not exercised shall expire and (y) subject to clause

      Section 3.6 Reorganization of Company to Corporate Form. The Members
acknowledge that the Company in its current form is unlikely to be the entity in
which equity interests will be offered to the public in a Company IPO. If, the
Board determines


                                       12

that it is necessary or appropriate to reorganize the Company, the parties
hereto agree to take such actions as may be determined by the Board to be
necessary to cause the Company to be reorganized (the "Reorganization") as a
Delaware corporation ("Newco") with equity ownership interests in Newco
consistent with the percentage interests set forth on Schedule 1 of the
Operating Agreement. The parties covenant and agree to enter into a
stockholders' agreement which embodies the terms and conditions of this
Agreement and the rights and obligations of the parties hereto with all
references to the Company being references to Newco, as appropriate, mutatis
mutandis.

disclosure, be held in confidence by the Recipient and, except with the prior
written consent of the disclosing party, shall not be disclosed by the Recipient

      Recipient or its Affiliates substantially consistent with this Section
      4.4; and

      (b) shall not be used by the Recipient or its Affiliates for any purposes

known to the Recipient; (b) is obtained by the Recipient on a non-confidential
basis from a third party, provided that the third party, to the knowledge of the
Recipient, is not or was not bound by a


                                       14

afford the disclosing party a reasonable opportunity to obtain a protective
order as to the Confidential Information, and further shall use reasonable
efforts to obtain reliable assurance that the Confidential Information actually
disclosed will be treated confidentially. Each of the Company and the Members
acknowledges that the terms of this Agreement and the Business Plan, as revised
from time to time, shall be considered Confidential Information. A Recipient
shall be responsible for any breach of this Section 4.4 by it or any of its
Representatives.

      Section 4.5 Public Statements. Except as required by applicable laws or

material nature regarding the Company or the Business without first having
consulted with the Company. The Members shall cooperate in good faith with
respect to the review of all such press releases and other public
communications distributed by either of them relating to the Company or the
Business. The Company may issue such press releases and public statements in
the normal course of its business as its senior officers shall determine to
be necessary or appropriate; provided, however, that if any such release or
statement may reasonably be expected to be adverse to any Member Group of any
Initial Member (so long as such Initial Member is a Qualifying Member), the
Company shall consult and coordinate with the designated public relations
officers of such Member Group at the earliest reasonably practicable time
prior to publishing such release or statement.

<PAGE>

                        (ii)  a Member may effect a Disposition to any Affiliate

                        (iii) a Member may pledge or otherwise encumber its
            Membership Interests under its debt arrangements; provided, that any
            pledgee or security holder which realizes on such pledge or

            a passive equity holder only, subject to the obligations of this
            Agreement (including under Section 5.1), but with no governance,
            voting or Board representation rights and no rights under Section
            8.1(d) and 8.2;

                        (iv)  at any time after the date that is two (2) years

            all applicable securities laws and regulations;

                        (ii) such Transfer will not result in the imposition of

            Code section 708(b) (or any comparable provision of state, local,
            foreign or provincial

                        of such tax termination are indemnified against by the
                        transferring Member (the "Transferor") or its transferee
                        (the "Transferee") in a manner reasonably acceptable to
                        the non-transferring Members; provided that the Members
                        shall cooperate in good faith, at the request of the
                        Member proposing the Transfer, to structure such
                        Transfer in a manner that does not give rise to any such
                        transfer tax or tax termination;

                                    (iii) such Transfer will not result in or
                        cause any material defaults under, any material breaches
                        of any material obligations contained in, or any
                        material failures of material conditions contained in,
                        any agreements to which the Company is a party, which
                        agreements, individually or in the aggregate, are
                        material to the Business;

                                    (iv)  other than in connection with a
                        Transfer to another Member pursuant to Section 8.2(d),
                        the Transferor effecting any such Transfer holds the
                        non-transferring Members harmless from all reasonable
                        out-of-pocket costs and expenses (including reasonable
                        attorneys' fees) incurred by the non-transferring
                        Members in order to complete the Transfer; and

                                    (v)   the Transferee in connection with a
                        Disposition shall have entered into a legally binding
                        commitment in form and substance reasonably satisfactory
                        to the non-transferring Members to be bound by this
                        Agreement and the Operating Agreement from and after the
                        date such Transferee becomes a Member.

                        (c) Dispositions to Affiliates. Any Disposition to an
            Affiliate shall be permitted only if (i) the Transferor has given
            ten (10) Business Days' prior written notice to the other Members
            identifying and providing relevant information about such Affiliate
            and (ii) the Transferor has complied with the applicable provisions
            of Section 8.1(b).

                        (d) Duty of First Offer.

                              (i) If any Member intends to offer (an "Offer") to
                        any Person other than an Affiliate of such Member all or
                        part of such Member's Membership Interest (which part
                        shall be at least twenty percent (20%) of such Member's
                        initial Membership Interest), such Member (the
                        "Prospective Seller") shall provide the other Members
                        written notice of


                                       28
<PAGE>

            such Offer (an "Offer Notice"). The Offer Notice shall set forth the
            portion of the Prospective Seller's Membership Interests with
            respect to which the Prospective Seller intends to make such Offer
            (the "Offered Interests") and the price and other material terms
            upon which the Prospective Seller intends to sell the Offered
            Interests (the "Offer Price").

                        (ii)  The receipt of an Offer Notice by the other
            Members from a Prospective Seller shall constitute an offer by such
            Prospective Seller to sell to each other Member the Offered
            Interests at the Offer Price. Such offer shall be open for 20 days
            after receipt of such Offer Notice by the other Members. During such
            20-day period, each other Member shall have the right to accept such
            offer as to all but not less than all of its pro-rata portion of the
            Offered Interests (with such other Members having the option to
            purchase at the Offer Price all Membership Interests not purchased
            by the other Members) by giving a written notice of acceptance (the
            "Notice of Acceptance") to the Prospective Seller and a copy of the
            Notice of Acceptance to each other Member prior to the expiration of
            such 20day period (any other Member so accepting such offer being an
            "Accepting Party"). Any other Member's rejection of the Prospective
            Seller's offer shall only be binding if such other Member has
            written notice of each of the other Members' final decision to
            accept or reject the Prospective Seller's offer.

                        (iii) If the Accepting Parties have agreed, in the
            aggregate, to purchase all, but not less than all, of the Offered
            Interests, the consummation of any such purchase by and sale to each
            such Accepting Party shall take place on such date, not later than
            30 days after receipt of the Notice of Acceptance received by the
            Prospective Seller, as such Accepting Party and the Prospective
            Seller shall select. Upon the consummation of such purchase and
            sale, the Prospective Seller shall (A) deliver to the Accepting
            Party written instruments of transfer with respect to the Offered
            Interest in form satisfactory to such Accepting Party duly executed
            by the Prospective Seller, and (B) shall assign all its rights under
            this Agreement and the Operating Agreement with respect to the
            Offered Interest purchased and sold pursuant to an instrument of
            assignment reasonably satisfactory to such Accepting Party.

                        (iv)  If the other Members do not elect to purchase all
            of the Membership Interests offered by the Prospective Seller during
            the 20-day offer period, then the Prospective Seller shall have a
            120-day period (the "Sale Period") following the 20-


                                       29
<PAGE>

            day offer period to enter into a binding agreement to sell all such
            Membership Interests to a third party (a "Third Party Purchaser") at
            a price at or higher than the Offer Price. If the Prospective Seller
            enters into a binding agreement to sell such Membership Interests to
            a Third Party Purchaser during the Sale Period, the Prospective
            Seller thereafter shall have an additional 60-day period following
            the execution of such binding agreement to close such sale.

                        (v) In the event that each other Member shall have
            received an Offer Notice from a Prospective Seller but the
            Prospective Seller shall have received a Notice of Acceptance from
            only one Accepting Party, the other Member which has elected not to
            purchase its pro rata share of the Offered Interests from the
            Prospective Seller may elect within 20 days after its receipt of a
            copy of the Notice of Acceptance to sell a pro rata portion of its
            Membership Interests at the Offer Price to the Accepting Party. Such
            sale by such other Member shall ratably reduce the Offered Interests
            to be sold to the Accepting Party by the Prospective Seller.

                        (vi) Anything in this Section 8.1(d) to the contrary
            notwithstanding, the provisions of this Section 8.1(d) will not be
            applicable to Transfers of Membership Interests made pursuant to and
            in compliance with Section 8.1(e).

                (e) Drag-Along Rights.

                        (i) Following the fifth anniversary of the Effective
            Date, if Members holding greater than fifty percent (50%) of the
            outstanding Membership Interests (the "Controlling Members") shall
            propose to sell, directly or indirectly, all of their Membership
            Interests in the Company (the "Controlling Interest"), in any
            transaction or series of related transactions, to any Person or
            Persons (a "Drag-Along Offer"), the Controlling Members may, at
            their option, require each of the other Members (the
            "Non-Controlling Members") to sell all of the Membership Interests
            owned or held by the Non-Controlling Members to such Person or
            Persons for the same pro-rata consideration (based on such Member's
            Membership Interests in the Company, assuming the conversion or
            exercise of all outstanding options, warrants or other convertible
            securities) and otherwise on the same terms and conditions upon
            which the Controlling Mem-

            bers sell their Membership Interests (a "Drag-Along Sale"). In the
            Drag-Along Sale, all Members holding securities convertible into
            Membership Interests shall either (A) exercise such securities prior
            to the consummation of the Drag-Along Sale and participate in such
            sale as Members holding such Membership Interests or (B) upon the
            consummation of the Drag-Along Sale, receive in exchange for such
            securities consideration equal to the amount determined by
            multiplying (1) the same pro-rata consideration (based on such
            Member's Membership Interests in the Company) received by the
            Members in connection with the Drag-Along Sale less the exercise
            price per percentage of the outstanding Membership Interests by (2)
            the percentage of Membership Interests represented by such rights.

                        (ii) The Controlling Members shall provide a written
            notice (the "Sale Notice") of the Drag-Along Sale to each of the
            Non-Controlling Members not later than the twentieth Business Day
            prior to the proposed consummation of the sale contemplated by the
            Drag-Along Offer. The Sale Notice shall contain written notice of
            the exercise of the Controlling Members' rights pursuant to this
            Section 8.1(e), setting forth the consideration to be paid by such
            Person or Persons and the other material terms and conditions of the
            Drag-Along Offer. Within fifteen (15) Business Days following the
            date the Sale Notice is given, each of the Non-Controlling Members
            shall deliver to the Controlling Members (A) written instruments of
            transfer in form reasonably satisfactory to the Controlling Members
            executed by the Non-Controlling Member, and (B) such other
            documents, certificates, resolutions, or other instruments as may be
            reasonably necessary to sell or otherwise dispose of such Membership
            Interest pursuant to the terms of the Drag-Along Offer. Each
            Non-Controlling Member shall consent to and raise no objections to
            the Drag-Along Sale and, upon request by the Controlling Members,
            shall waive any appraisal or dissenters' rights in respect of such
            Drag-Along Sale, and take all other actions reasonably necessary or
            desirable to cause the consummation of such Drag-Along Sale on the
            terms proposed by the Controlling Members, including, without
            limitation, (i) if the Drag-Along Sale is structured as a sale of
            Membership Interests, each Non-Controlling Member will sell all of
            its Membership Interests and rights to acquire Membership Interests
            on the terms and conditions approved by the Controlling Members,
            (ii) if the Drag-Along Sale is structured as a merger or
            consolidation, each Non-Controlling Member will vote in favor
            thereof and will not exercise any dissenters' rights of appraisal it
            may have under


                                       31
<PAGE>

            any applicable law and (iii) if the Drag-Along Sale is structured as
            a sale of all or substantially all of the assets of the Company,
            each Non-Controlling Member will vote in favor thereof and, if
            applicable, will vote in favor of the subsequent dissolution and
            liquidation of the Company.

                        (iii) Promptly after the consummation of the sale of the
            Membership Interests of the Controlling Members and the
            Non-Controlling Members to such Person or Persons pursuant to the
            Drag-Along Offer, the Controlling Members shall remit to each of the
            Non-Controlling Members the pro rata portion of the total sales
            price attributable to the Membership Interests of such
            Non-Controlling Members sold pursuant thereto less a pro-rata
            portion of the reasonable out-of-pocket costs and expenses
            (including reasonable attorneys= fees) incurred by the Controlling
            Members in connection with such sale.

                        (iv)  If, at the end of the 75day period following the
            giving of the Sale Notice, the Controlling Members shall not have
            completed the sale of all the Controlling Interest and the
            Membership Interests transferred to the Controlling Members pursuant
            to Section 8.1(e)(ii), the Controlling Members shall return to the
            Non-Controlling Members the documents delivered to the Controlling
            Members pursuant to Section 8.1(e)(ii)(A) and 8.1(e)(ii)(B).

                        (v)   Except as expressly provided in this Section
            8.1(e), the Controlling Members shall have no obligation to any
            Non-Controlling Member with respect to the sale or other disposition
            of any Membership Interests owned by such Non-Controlling Member in
            connection with this Section 8.1(e). Anything herein to the contrary
            notwithstanding, the Controlling Members shall have no obligation to
            any Non-Controlling Member to sell or otherwise dispose of any
            Controlling Interest pursuant to this Section 8.1(e) or as a result
            of any decision by the Controlling Members not to accept or
            consummate any Drag-Along Offer or sale with respect to the
            Controlling Interest (it being understood that any and all such
            decisions shall be made by each of the Controlling Members in its
            sole discretion). No Non-Controlling Member shall be entitled to
            make any Transfer of Membership Interests directly to any Person
            pursuant to an Offer (it being understood that all such Transfers
            shall be made only on the terms and pursuant to the procedures set
            forth in this Section 8.1(e)).

                                       32
<PAGE>


            Nothing in this Section 8.1(e) shall affect any of the obligations
            of any of the Members under any other provision of this Agreement.

                        (vi)  No Non-Controlling Member shall be required to
            make any representations and warranties to any Person or Persons in
            connection with the sale made pursuant to the Drag-Along Offer
            except as to (A) good title and the absence of liens with respect to
            such Non-Controlling Member's Membership Interests, (B) the
            corporate or other existence of such Non-Controlling Member and (C)
            the authority for and the validity and binding effect of, and
            absence of any conflicts under the charter documents and materials
            agreements of, such Non-Controlling Member as to, any agreements
            entered into by such Non-Controlling Member in connection with such
            sale. Each Member shall be obligated to agree to join in any
            indemnification to which the Controlling Members agree on the same
            terms as agreed to by the Controlling Members; provided, that the
            liability of any Non-Controlling Member with respect to such
            indemnification shall not exceed the amount of the net proceeds from
            such Drag-Along Sale.

                        (vii) Anything in this Section 8.1(e) to the contrary
            notwithstanding, the provisions of this Section 8.1(e) shall not be
            applicable (A) to any sale of Membership Interests pursuant to a
            Company IPO or (B) at any time after a Company IPO.

            Section 8.2 Preemptive Rights.

            (a) Except as otherwise provided in Section 8.2(c), if the Company
authorizes the offer or sale to any Person of membership interests or other
equity securities in the Company ("New Interests") or of options or rights to
acquire New Interests ("New Rights"), then the Company will first offer to each
Initial Member a fraction (equal to such Initial Member's Membership Interest in
the Company) of such New Interests or New Rights. Each Initial Member shall be
entitled to purchase all or a portion of the New Interests or New Rights offered
to it at the same price and on the same terms and conditions as such New
Interests or New Rights are to be offered to any other Persons. Each Initial
Member must exercise its purchase rights hereunder within 20 days after written
notice from the Company describing in reasonable detail the New Interests or New
Rights being offered, the purchase price thereof, the payment terms thereof and
such Initial Member's percentage allotment.


                                       33
<PAGE>

            (b) During the 120 days following the expiration of the offering
period described above, the Company shall be free to sell any New Interests or
New Rights that the Initial Members have not elected to purchase on terms and
conditions no more favorable to the purchasers thereof than those offered to the
Initial Members. If any New Interests or New Rights are not sold during such
120-day period in accordance with this Section 8.2(b), then the provisions of
this Section 8.2 shall automatically and immediately be reinstated, and shall
automatically and immediately reapply to the offer or sale of such New Interests
or New Rights.

            (c) The provisions of this Section 8.2 shall not apply to (i) the
issuance and sale, in accordance with Section 5.4, to employees, officers or
managers of the Company of New Interests or New Rights representing up to
fifteen percent (15%) of the outstanding Membership Interests in the Company as
of the Effective Date, (ii) the issuance and sale of New Interests in an initial
public offering of equity interests in the Company (or any successor to the
Company) registered under the Securities Act, (iii) the issuance and sale of New
Interests to one or more Investors in financings prior to a Company IPO in an
aggregate amount equal to up to ten percent (10%) of the fully diluted
outstanding membership interests in the Company (or any successor to the
Company) or (iv) the issuance or sale of any New Interests or New Rights in an
equity-for-equity acquisition. The provisions of this Section 8.2 shall
terminate upon a Company IPO.

            (d) The rights of a Member under this Section 8.2 may be waived in
writing in any specific instance by any Member.

      Section 8.3 Other Transfer Matters.

            (a) Member Consent to Transfers. Upon request of any Member
effecting a Transfer permitted by and in compliance with the provisions of
Section 8.1, the other Members shall execute a written consent in form and
substance reasonably satisfactory to such other Members, admitting the
Transferee as a member of the Company, entitled to all the privileges and
subject to all the obligations of this Agreement and the Operating Agreement
approving such permitted Transfer. The Members acknowledge that an award of
damages for failure to comply with the foregoing covenant would not be an
adequate remedy for the Member attempting to effect a permitted Transfer, and
accordingly expressly authorize such Member to bring an action against the
non-transferring Members to compel the specific performance by such
non-transferring Members of their obligations to execute a written consent as to
such permitted Transfer.

            (b) Prohibited Transfers. Any purported Transfer that is not made in
accordance with this Article VIII shall be null and void ab initio.

      Section 9.1 No Termination of Company. Except as expressly provided in
this Agreement, no Member shall or shall seek to dissolve, terminate or
liquidate the Company, and no Member shall petition a court for the partition,
dissolution, termination or liquidation of the Company or its property. Each of
the Members hereby irrevocably waives any and all rights that it may have to
maintain an action to partition Company property or to compel any sale or
transfer thereof.

      Section 9.2 Term and Termination of Agreement. This Agreement shall
continue in full force and effect until the earliest to occur of (a) termination
by unanimous written consent of the Members, (b) the date on which all
Membership Interests are held by a single Person, (c) the final dissolution and
completion of winding up of the Company in accordance with this Agreement and
the Operating Agreement, or (d) a Company IPO; provided that this Agreement
shall continue in force thereafter solely with respect to 4.4, 10.1, 10.4 and
10.6. The Company shall dissolve and commence winding up upon the earliest to
occur of (a) the unanimous written consent of the Members and (b) the happening
of any event that makes it unlawful or impossible to carry on the Business.
