            2. Board of Directors.

            (a) To the extent permitted by law, each Stockholder shall vote all
voting securities of the Company over which such Stockholder has voting
control, and shall take all other reasonably necessary or desirable actions
within such Stockholder's control (whether in such Stockholder's capacity as a
stockholder, director, member of a board committee or officer of the Company or
otherwise, and including, without limitation, attendance at meetings in person
or by proxy for purposes of obtaining a quorum and execution of written consents
in lieu of meetings), and the Company shall take all necessary and desirable
actions within its control (including, without limitation, calling special board
and shareholder meetings), so that:

            (i) the authorized number of directors of the Board shall be seven;

            (ii) holders of record of a majority of the Cornerstone Shares
      entitled to vote for directors of the Board will designate three of the
      seven total directors of the Board (each a "Cornerstone Director") (the
      three Cornerstone Directors shall initially be John A. Downer, Michael E.
      Najjar and Mark Rossi);

            (iii) any director designated pursuant to clause (ii) above shall be
      removed from the Board or any committee thereof (with or without cause) at
      the written request of the Stockholder or Stockholders which have the
      right to designate such director hereunder, but only upon such written
      request and under no other circumstances (in each case, determined on the
      basis specified in clause (ii) above);

            (iv) in the event that any director designated hereunder for any
      reason ceases to serve as a member of the Board or any committee thereof
      during such director's term of office, the resulting vacancy on the Board
      or committee shall be filled by a director designated by the Stockholders
      referred to in clause (ii) above; and

            (v) at the Board's election, the composition of the board of
      directors (or any similar governing body) of any of the Company's
      Subsidiaries shall be the same as the Board; and

            (vi) the Stockholders will agree to expand the size of the Board to
      the extent necessary to fulfill the Company's obligations to any holder of
      its preferred stock under the Company's certificate of incorporation.

            (b) BT Observer. Prior to the consummation of a Qualified Public
Offering, so long as BT and its Affiliates (and not any of their respective
assigns) own at least 5% of the outstanding shares of Common Stock, BT and its
Affiliates who own Stockholder Shares (and not any of their respective assigns)
shall appoint a representative, which representative must be reasonably
acceptable to Cornerstone (the "BT Observer") (the initial BT Observer shall be
Cathy Madigan). BT and its Affiliates who own Stockholder Shares (and not any of
their respective assigns) may remove any such representative or appoint a new
representative if a vacancy in such position occurs for any reason by delivery
of a written notice to the Secretary of the Company; provided that any such new
representative must be reasonably acceptable to Cornerstone. The Company or the
applicable members of the Board will give the BT Observer oral or written notice


                                    - 5 -
   6

of each meeting of the Board (whether annual or special) at the same time and in
the same manner as oral or written notice is given to the applicable members of
the Board (which notice may be waived by the BT Observer). Notwithstanding the
foregoing, if the BT Observer attends (or, in the case of a telephonic meeting,
listens by telephone to) any such meeting of the Board, then the BT Observer
shall be deemed to have had proper notice of such meeting. Notwithstanding
anything contained herein to the contrary, the failure of the BT Observer to be
given notice of a meeting of the Board pursuant to the immediately preceding
sentence or to attend such meeting shall not in any way affect the authority of
the Board to have or to adopt resolutions at such meeting or the legitimacy of
any actions taken by the Board at such meeting. Subject to the foregoing, the
Company will permit the BT Observer to attend (or, in the case of a telephonic
meeting, to listen by telephone to) each meeting of the Board as a non-voting
observer. The Company shall provide the BT Observer all written materials and
other information (including copies of meeting minutes) given to the members of
the Board in connection with any such meeting at the same time as such
information is delivered to the members of the Board and, if the BT Observer
does not attend (or, in the case of a telephonic meeting, does not listen by
telephone to) a meeting of the Board, the BT Observer will be entitled, upon
request, to receive a written or oral summary of the meeting from the Secretary
of the Company. If the Company takes any action by written consent in lieu of a
meeting of the Board, then the Company shall give prompt written notice of such
action to the BT Observer.

            (c) The Company shall reimburse the directors of the Board for all
reasonable out-of-pocket expenses borne by such directors in connection with the
performance of their duties as directors of the Company and the BT Observer in
connection with attendance in any meeting of the Board.

            (d) If any party fails to designate in writing a representative to
fill a director position pursuant to the terms of this Section 2, the election
of a Person to such director position shall be accomplished in accordance with
the Company's Articles of Incorporation and by-laws and applicable law. In the
event that, at any time, any provision of the Company's Articles of
Incorporation or by-laws is inconsistent with the requirements of any provision
of this Section 2, the Stockholders shall take such action as may be necessary
to amend any such provision in the Company's Articles of Incorporation or
by-laws, as the case may be, to conform with such requirements.

            3. Conflicting Agreements. Each Stockholder represents that such
Stockholder has not granted and is not a party to any proxy, voting trust or
other agreement which is inconsistent with or conflicts with the provisions of
this Agreement, and no holder of Stockholder Shares shall grant any proxy or
become party to any voting trust or other agreement which is inconsistent with
or conflicts with the provisions of this Agreement.

            4. Restrictions on Transfer of Stockholder Shares.

            (a) General Restrictions.

            (i) Prior to the earlier of (x) the second anniversary of the date
      hereof and (y) the first day after the period commencing on the date
      hereof and ending on the day the Company's financial statements are filed
      with the SEC for the first full fiscal quarter after


                                    - 6 -
   7

      the Company consummates an initial Public Offering, subject to Section 7
      hereof, an MEIC Holder may Transfer Stockholder Shares only (A) if such
      MEIC Holder is exercising a tag-along right granted to such MEIC Holder
      pursuant to Section 4(c), then to any Person, provided, that such Person
      shall have complied with the requirements of Section 4(d)(ii), or (B)
      pursuant to the terms of Section 5.

            (ii) On or after the earlier of (x) the second anniversary of the
      date hereof and (y) the first day after the period commencing on the date
      hereof and ending on the day the Company's financial statements are filed
      with the SEC for the first full fiscal quarter after the Company
      consummates an initial Public Offering, subject to Section 7 hereof, an
      MEIC Holder may Transfer Stockholder Shares only (A) in Public Sales, (B)
      if such MEIC Holder has complied with the terms and requirements of
      Section 4(b) or if such MEIC Holder is exercising a tag-along right
      granted to such MEIC Holder pursuant to Section 4(c), then to any Person,
      provided, that such Person shall have complied with the requirements of
      Section 4(d)(ii), or (C) pursuant to the terms of Section 5.

            (iii) Subject to Section 7 hereof, an Investor may Transfer
      Stockholder Shares only (A) in Public Sales, (B) if such Investor has
      complied with the terms and requirements of Sections 4(b) and 4(c), to the
      extent applicable, or if such Investor is exercising a tag-along right
      granted to such Investor pursuant to Section 4(c), then to any Person,
      provided, that such Person shall have complied with the requirements of
      Section 4(d)(ii), or (C) pursuant to the terms of Section 5.

            (iv) Notwithstanding any other provision of this Agreement to the
      contrary, in the event that a Regulated Stockholder shall reasonably and
      in good faith determine that if such Regulated Stockholder shall continue
      to hold some or all of the Stockholder Shares held by such Regulated
      Stockholder, there is a material risk that such ownership will result in a
      Regulatory Problem and such Regulatory Problem cannot be remedied by
      converting such Stockholder Shares into another class of Stockholder
      Shares, then, subject to Section 7 hereof, such Regulated Stockholder, may
      Transfer all Stockholder Shares necessary to prevent such Regulatory
      Problem to any Person without complying with the terms and requirements of
      Sections 4(b) and 4(c); provided, that (w) such Regulated Stockholder
      shall have delivered a written notice to the Company describing in
      reasonable detail the nature of the Regulatory Problem, the amount, type
      and class of Stockholder Shares to be Transferred and the identity of such
      Person, (x) such Person is not a direct competitor of the Company or any
      of its Subsidiaries, (y) such Person is reasonably acceptable to
      Cornerstone and the Board, and (z) such Person shall have complied with
      the requirements of Section 4(d)(ii). Without limiting the foregoing, at
      the request of such Regulated Stockholder, the Company shall provide (and
      authorize such Regulated Stockholder, to provide) financial and other
      information concerning the Company to any prospective purchaser of such
      securities owned by such Regulated Stockholder. The Company shall not be
      required to provide any such information unless the recipient thereof
      signs a confidentiality agreement reasonably satisfactory to the Company.

            (b) Right of First Refusal granted to the Company and the
Cornerstone Investors. Subject to Section 4(d)(i) (all terms defined in this
Section 4(b) shall be for purposes of this Section 4(b) only):


                                    - 7 -
   8

            (i) If at any time any MEIC Holder, any Randolph Investor, any BT
      Investor or any Other Investors (a "Selling Holder") proposes to Transfer
      any Stockholder Shares (other than pursuant to a Public Sale, pursuant to
      the terms of Section 5, or if such Selling Holder is exercising a
      tag-along right granted to such Selling Holder pursuant to Section 4(c)),
      then such Selling Holder will, not fewer than twenty-five (25) business
      days prior to making such Transfer, give notice (the "Transfer Notice") to
      the Cornerstone Investors and to the Company specifying (x) the
      Stockholder Shares proposed to be Transferred (the "Offered Shares"), (y)
      the price (the "Offered Price") and the other terms and conditions upon
      which such Selling Holder proposes to Transfer such Offered Shares, and
      (z) the proposed Transferee(s). Notwithstanding the foregoing, each
      potential Selling Holder agrees to use its best efforts to notify the
      Cornerstone Investors and the Company within a reasonable time of the
      occurrence of any discussions with any potential proposed Transferee which
      have a reasonable likelihood of giving rise to such potential Selling
      Holder having an obligation to deliver a Transfer Notice pursuant to this
      Section 4(b).

            (ii) The Transfer Notice will constitute an irrevocable offer (for
      the time periods set forth in items (iii) and (iv) below) to Transfer any
      of the Offered Shares to the Company and the Cornerstone Investors at the
      Offered Price and on the terms specified in the Transfer Notice (the
      "Offer to Sell"), except that if the proposed Transfer is to be wholly or
      partly for consideration other than cash, then the Offer to Sell will
      constitute an offer to Transfer the Offered Shares to the Company and the
      Cornerstone Investors for a cash purchase price equal to the amount of
      cash (if any) specified in the Transfer Notice, plus the fair market value
      determined in the good faith judgement of the Board, at the date of the
      Transfer Notice, of such non-cash consideration.

            (iii) The Company will have fifteen (15) business days after its
      receipt of the Transfer Notice (the "Company Exercise Period") during
      which to notify the Selling Holder and the Cornerstone Investors in
      writing of its election to purchase all or any portion of the Offered
      Shares (an "Acceptance Notice").

            (iv) If the Company has not elected to purchase all of the Offered
      Shares, each Cornerstone Investor will have twenty (20) business days
      after its receipt of the Transfer Notice (the "Cornerstone Exercise
      Period") during which to notify the Selling Holder and the Company in
      writing of its election to purchase all but not less than all of the
      Offered Shares which the Company has not elected to purchase (such shares,
      the "Cornerstone Offered Shares") (such written notice, also an
      "Acceptance Notice"). Any Cornerstone Investor who delivers an Acceptance
      Notice shall be referred to herein as a "Purchasing Cornerstone Investor".
      If the Purchasing Cornerstone Investors elect to purchase in the aggregate
      more than the Cornerstone Offered Shares, then the Cornerstone Offered
      Shares shall be sold among the Purchasing Cornerstone Investors pro rata
      based upon the number of Stockholder Shares then owned by such Purchasing
      Cornerstone Investors or in such other manner as the Purchasing
      Cornerstone Investors may agree.

            (v) Upon the delivery of the Acceptance Notice(s), the Company
      and/or the Purchasing Cornerstone Investor(s), as the case may be, and the
      Selling Holder shall be firmly bound to consummate the purchase and sale
      of the applicable Offered Shares in accordance with the Transfer Notice,
      the Acceptance Notice(s) and the terms hereof. Subject


                                    - 8 -
   9

      to the provisions hereof, within ninety (90) days after the Selling
      Holder's receipt of the last Acceptance Notice, the Company and/or the
      Purchasing Cornerstone Investor(s), as the case may be, shall purchase and
      the Selling Holder shall sell the applicable Offered Shares at a mutually
      agreeable time and place (the "Offered Shares Closing").

            (vi) At the Offered Shares Closing, the Selling Holder shall deliver
      to the Company and/or the Purchasing Cornerstone Investor(s), as the case
      may be, certificates representing the Offered Shares (which Offered Shares
      shall be free and clear of any liens or encumbrances) to be purchased by
      the Company and/or the Purchasing Cornerstone Investor(s), as the case may
      be, and the Company and/or the Purchasing Cornerstone Investor(s), as the
      case may be, shall deliver to the Selling Holder the applicable purchase
      price for such Offered Shares by wire transfer of immediately available
      funds to an account(s) designated by such Selling Holder.

            (vii) If the Company and the Cornerstone Investors collectively do
      not elect to purchase any or all of the Offered Shares in accordance with
      Section 4(b)(iii) and 4(b)(iv), then, provided the Selling Holder has also
      complied with the provisions of Section 4(c), if applicable, and no
      Transferee is an Affiliate of the Selling Holder, the Selling Holder may
      Transfer any or all of such Offered Shares (unless reduced pursuant to the
      exercise of rights granted to other Stockholders in Section 4(c)), at a
      price which is not less than the price specified in the Transfer Notice
      and on other terms and conditions which are not materially more favorable
      in the aggregate to any Transferee thereof than those specified in the
      Transfer Notice, to any Person(s), but only to the extent that a binding
      purchase and sale agreement has been executed between such Selling Holder
      and such Transferee within 120 days after expiration of the Cornerstone
      Exercise Period. Any Stockholder Shares not Transferred pursuant to such
      an agreement within such 120-day period will be subject to the provisions
      of this Section 4(b) upon subsequent Transfer.

            (viii) The provisions of this Section 4(b) shall terminate upon the
      consummation of a Qualified Public Offering; provided, that with respect
      to any MEIC Holder, the provisions of this Section 4(b) shall terminate

      Investors elects to participate in such Transfer, each of the Tagging
      Investors shall be entitled to sell in such contemplated Transfer, at the
      same price and on the same terms, up to a number of each class of
      Stockholder Shares to be Transferred equal to the product of (I) a
      fraction, the numerator of which is the number of Stockholder Shares to be
      sold by the Cornerstone Transferring Stockholder (after giving effect to
      any reduction in the number of Stockholder Shares to be sold by such
      Cornerstone Transferring Stockholder as a result of the inclusion of such
      Stockholder Shares owned by such Other Investors) and the denominator of
      which is the aggregate number of Stockholder Shares owned by the
      Cornerstone Transferring Stockholder immediately prior to such Transfer,
      multiplied by (II) the total number of Stockholder Shares owned by such
      Other Investor immediately prior to such Transfer. Each Stockholder
      Transferring Stockholder Shares pursuant to this Section 4(c)(i) shall pay
      its pro rata share (based on the number of Stockholder Shares to be sold)
      of the expenses incurred by the Stockholders in connection with such
      Transfer and shall take all necessary and desirable actions as reasonably
      directed by the Cornerstone Transferring Stockholder in connection with
      the consummation of such Transfer, including without limitation executing
      the applicable purchase agreement. The Cornerstone Transferring
      Stockholder shall cause all applicable transferee(s) to execute a joinder
      to this Agreement with respect to all Stockholder Shares Transferred
      pursuant to this Section 4(c)(i). Any Transfer made by a Cornerstone
      Transferring Stockholder pursuant to this Section 4(c)(i) or pursuant to
      Section 4(c)(ii) shall satisfy the following conditions, (i) upon the
      consummation of such Transfer, each Stockholder participating in such
      Transfer will be entitled to receive (x) the same form and amount (on a
      share-for-share basis) of consideration, with respect to each share of
      Common Stock sold in such Transfer and (y) the same form and amount (on a
      share-for share basis) of consideration, with respect to each shares of
      Convertible Preferred Stock in such Transfer and (ii) if any holder of a
      Common Stock or Convertible Preferred Stock is given the option as to the
      form and amount of consideration to be received in connection with such
      Transfer (other than to remedy a Regulatory Problem for such holder), then
      each holder of Common Stock or Convertible Preferred Stock, as the case
      may be, shall have given the same option. In connection with any Transfer
      made pursuant to this Section 4(c) each Other Investor shall be entitled
      to receive, and the Company and/or the Cornerstone Transferring
      Stockholder shall deliver all information relating to the Company and its
      Subsidiaries as such Other Investor shall reasonably request. The
      Cornerstone Transferring Stockholder shall deliver to each Other Investor
      a copy of the acquisition agreement (and related documents) relating to
      any Transfer subject to this Section 4(c) in a reasonably timely manner to
      allow for adequate review by each of the Other Investors and shall include
      in the disclosure schedules attached thereto any information reasonably
      requested to be included therein by such Other Investor. The right of the
      BT Investors to participate in a Transfer pursuant to this Section 4(c)
      shall not be contingent upon such BT Investor providing any indemnity in
      connection with any such Transfer, unless the Cornerstone Transferring
      Stockholder and all other sellers provide such an indemnity, and in the
      event that all sellers are required to provide an indemnity in connection
      with such Transfer, all parties hereto agree to enter into a contribution
      agreement among themselves which provides that no Investor shall be liable
      for more than the lesser of (A) its pro rata shares of any such
      indemnification payments (based upon the total consideration received by
      such Investor divided by the total consideration received by all sellers
      in such Transfer) and (B) the net


                                    - 10 -
   11

      proceeds actually received by such Investor as consideration for its
      shares of Common Stock in such Transfer.

            (ii) Tag Along Rights granted to MEIC. Subject to Section 4(d)(i),
      at least 10 business days prior to any Transfer after the date six months
      after the date hereof by any of the Investors (the "Transferring
      Stockholder") of any voting Stockholder Shares to a Person that is not an
      Affiliate of any Transferring Stockholder, and is not a Stockholder or the
      Company (other than pursuant to a Public Sale, pursuant to the terms of
      Section 5, a Transfer to the Company or any Cornerstone Investor pursuant
      to the terms of Section 4(b), or if such Transferring Stockholder is
      exercising a tag-along right granted to such Transferring Stockholder
      pursuant to this Section 4(c)), the Transferring Stockholder shall deliver
      a written notice (the "Sale Notice") to MEIC or any of its Affiliates (and
      not any of their respective assigns) and to the Company, specifying in
      reasonable detail the identity of the prospective transferee(s), the class
      and the number of the voting Stockholder Shares to be Transferred, and the
      other material terms and conditions of such contemplated Transfer. MEIC or
      any of its Affiliates (and not any of their respective assigns) may elect
      to participate in such contemplated Transfer by delivering written notice
      to the Transferring Stockholder within 7 business days after its receipt
      of the Sale Notice. If MEIC or any of its Affiliates (and not any of their
      respective assigns) elects to participate in such Transfer, MEIC or any of
      its Affiliates (and not any of their respective assigns) shall be entitled
      to sell in such contemplated Transfer, at the same price and on the same
      terms, a number of each class of voting Stockholder Shares to be
      Transferred equal to the product of (x) the quotient determined by
      dividing the percentage of such class of Stockholder Shares owned by MEIC
      or any of its Affiliates (and not any of their respective assigns)
      (calculated on a fully diluted basis) by the aggregate percentage of such
      class of Stockholder Shares owned collectively by the Stockholders
      (calculated on a fully diluted basis) and (y) the aggregate number of
      voting Stockholder Shares of such class to be sold in such contemplated
      Transfer. If MEIC or any of its Affiliates (and not any of their
      respective assigns) does not elect to participate in such Transfer, then
      the Transferring Stockholder may Transfer any or all of the voting
      Stockholder Shares described in the applicable Sale Notice, at a price
      which is not more than the price specified in the applicable Sale Notice
      and on other terms and conditions which are not materially more favorable
      in the aggregate to the Transferring Stockholder than those specified in
      the applicable Sale Notice, to the prospective transferee(s) specified in
      the applicable Sale Notice, but only to the extent that a binding purchase
      and sale agreement has been executed between such Transferring Stockholder
      and any such prospective transferee(s) within 130 days after the
      Transferring Stockholder delivered the applicable Sale Notice to MEIC. Any
      Stockholder Shares not Transferred pursuant to such an agreement within
      such 130-day period will be subject to the provisions of this Section
      4(c)(ii) upon subsequent Transfer. Each Stockholder Transferring voting
      Stockholder Shares pursuant to this Section 4(c)(ii) shall pay its pro
      rata share (based on the number of voting Stockholder Shares to be sold)
      of the expenses incurred by the Stockholders in connection with such
      Transfer and shall take all necessary and desirable actions as reasonably
      directed by the Transferring Stockholder in connection with the
      consummation of such Transfer, including without limitation executing any
      applicable purchase agreement. The Transferring Stockholder shall cause
      all applicable transferee(s) to execute a joinder to this Agreement with
      respect to all Stockholder Shares Transferred pursuant to this Section
      4(c)(ii).

            (iii) For purposes of this Section 4(c), (a) Class A Common, Class B
      Common and Class C Common shall be deemed to be the same class of
      Stockholders Shares, (b) Series A Convertible Preferred, Series B
      Convertible Preferred and Series C Convertible Preferred shall be deemed
      to be the same class of Stockholder Shares, and (c) Convertible Preferred
      and Common Stock shall be deemed to be different classes of Stockholder
      Shares; provided, however, that, notwithstanding the foregoing, Class B
      Common and Series B Convertible Preferred shall not be deemed voting
      Stockholder Shares for purposes of subparagraph (ii) above.

            (iv) The provisions of Sections 4(c)(i) shall terminate upon the
      consummation of a Qualified Public Offering. The provisions of Section
      4(c)(ii) shall terminate upon the earlier of (x) the consummation of an
      initial Public Offering and (y) the date MEIC or any of its Affiliates
      (and not any of their respective assigns) cease to own any Stockholder
      Shares.

            (d) Permitted Transfers.

            (i) The restrictions contained in Sections 4(a), 4(b) and 4(c) shall
      not apply with respect to any Transfer of Stockholder Shares by any
      Stockholder (A) in the case of an individual Stockholder, pursuant to
      applicable laws of descent and distribution or to any member of such
      Stockholder's Family Group, (B) in the case of a non-individual
      Stockholder, to its employees or Affiliates, (C) in the case of
      Cornerstone, to its partners in connection with a distribution by
      Cornerstone of Stockholder Shares held by Cornerstone; provided, in each
      case, that any such transferee shall have complied with the requirements
      of Section 4(d)(ii).

            (ii) Prior to any proposed transferee's acquisition of Stockholder
      Shares pursuant to a Transfer permitted by Section 4(a)(i)(A), 4(a)(ii)(B)
      or 4(a)(iii)(B) or Section 4(d)(i), such proposed transferee must agree to
      take such Stockholder Shares subject to and to be fully bound by the terms
      of this Agreement applicable to such Stockholder Shares by executing a
      joinder to this Agreement substantially in the form attached hereto as
      Exhibit A and delivering such executed joinder to the Secretary of the
      Company prior to the effectiveness of such Transfer (unless such Transfer
      is pursuant to applicable laws of descent and distribution, in which case,
      such executed joinder shall be delivered to the Secretary of the Company
      as soon as reasonably possible after such Transfer). All transferees
      acquiring Stockholder Shares and executing a joinder in compliance with
      this Section 4(d)(ii) are collectively referred to herein as "Permitted
      Transferees".

            (e) If (i) any event occurs pursuant to which Micron Electronics,
Inc. ceases to directly or indirectly own the MEIC Shares, (ii) any Transfer of
a majority interest in the residual equity securities of a Stockholder owning
Stockholder Shares occurs other than a Transfer to an Affiliate of Micron
Electronics, Inc., or (iii) any Stockholder Transfers Stockholder Shares to an
Affiliate and an event occurs which causes such Affiliate to cease to be an
Affiliate of such Stockholder, such event or Transfer shall be deemed a Transfer
of Stockholder Shares subject to all of the restrictions on Transfers of
Stockholder Shares set forth in this Agreement, including without limitation,
this Section 4.

            5. Approved Sale.

                  (a) If the holders of a majority of the shares of voting
Stockholder Shares then outstanding, voting together as if a single class, (the
"Approving Stockholders") approve a sale of all or substantially all of the
Company's assets determined on a consolidated basis or a sale of all (or, for
accounting, tax or other reasons, substantially all) of the Company's
outstanding capital stock (other than capital stock which is not Common Stock or
convertible into Common Stock) (whether by merger, recapitalization,
consolidation, reorganization, combination or otherwise) to an Unaffiliated
Third Party or group of Unaffiliated Third Parties (each such sale, an "Approved
Sale"), then each holder of Stockholder Shares will vote for, consent to and
raise no objections against such Approved Sale subject to the terms set forth
below. In connection with any Stockholders exercising their rights under this
Section 5(a), such Stockholders shall send a written notice at least ten (10)
business days prior to any Approved Sale to all other Stockholders setting forth
the principal terms of the proposed Approved Sale. If the Approved Sale is
structured as (i) a merger or consolidation, each holder of Stockholder Shares
will waive any dissenters' rights, appraisal rights or similar rights in
connection with such merger or consolidation or (ii) a sale of stock, each
holder of Stockholder Shares will agree to sell all of its Stockholder Shares
and rights to acquire Stockholder Shares on the same terms and conditions as
applicable to all of the Stockholder Shares held by the Approving Stockholders.
Each holder of Stockholder Shares will take all reasonably necessary or
desirable actions in connection with the consummation of the Approved Sale as
reasonably requested by the Investors approving such Approved Sale including
without limitation (but subject to Section 5(c)) executing any applicable
purchase agreement.

                  (b) Each Stockholder will bear their pro-rata share (based
upon the number of shares sold) of the costs of any sale of Stockholder Shares
pursuant to an Approved Sale to the extent such costs are incurred for the
benefit of all holders of Stockholder Shares and are not otherwise paid by the
Company or the acquiring party. Costs incurred by any Stockholder on their own
behalf will not be considered costs of the transaction hereunder.

                  (c) The obligations of the Stockholders with respect to any
Approved Sale are subject to the satisfaction of the following conditions: (i)
in connection with the consummation of such Approved Sale, each Stockholder will
be entitled to receive (x) the same form and amount (on a share-for-share basis)
of consideration, with respect to each share of Common Stock sold in such
Approved Sale and (y) the same form and amount (on a share-for-share basis) of
consideration, with respect to each share of Convertible Preferred Stock sold in
such Approved Sale, (ii) if any holder of Common Stock or Convertible Preferred
Stock is given the option as to the form and amount of consideration to be
received in connection with such Approved Sale (other than to remedy a
Regulatory Problem for such holder), then each holder of Common Stock or
Convertible Preferred Stock, as the case may be, shall be given the same option,
(iii) if Cornerstone or any Affiliate of Cornerstone owns directly or indirectly
more than 5% of any class of capital stock of any of the Unaffiliated Third
Parties, then such Approved Sale shall have been approved by at least five of
the seven members of the Board (each such number to be reduced by any member of
the Board who is not eligible to vote on such Approved Sale) and the Board shall
have received a fairness opinion from a nationally recognized investment banking
firm with respect to the terms of such Approved Sale. No holder of BT Shares
shall be required to participate in an Approved Sale unless such holder receives
consideration that does not cause a Regulatory Problem for such holder or any of
its Affiliates, and (iv) no Investor shall be required to provide an indemnity
in connection with any



                                    - 13 -
   14

Approved Sale, unless all sellers in such Approved Sale provide such an
indemnity, and in the event that all sellers are required to provide an
indemnity in connection with the Approved Sale, all parties hereto agree to
enter into a contribution agreement among themselves which provides that no
Investor shall be liable for more than the less of (A) its pro rata share of
such indemnification payments (based upon the total consideration received by
such holder divided by the total consideration received by all seller sin such
Approved Sale) and (B) the net proceeds actually received by such holder as
consideration for its shares of proceeds actually received by such holder as a
consideration for its shares of capital stock of the Company in such Approved
Sale. In connection with any Approved Sale, each Investor shall be entitled to
receive, and the Company shall deliver all information relating to the Company
and its Subsidiaries as such Investor shall reasonably request. The Company
shall deliver to each Investor a copy of the acquisition agreement (and related
documents) relating to any Approved Sale in a reasonably timely manner to allow
for adequate review by the Investors and shall include in the disclosure
schedules attached thereto any information reasonably requested to be included
therein by such Investor. Notwithstanding anything contained herein to the
contrary, the term "consideration" as used in this subsection (c) shall not
include any management, advisory, closing, legal or similar fees received by any
Stockholder or any Affiliate of any Stockholder in connection with an Approved
Sale.

                  (d) The provisions of this Section 5 will terminate upon the
occurrence of the earlier of (i) the consummation of a Qualified Public Offering
and (ii) the date on which Cornerstone and its Affiliates no longer own at least
25% of the then outstanding shares of Common Stock.

            6. Financial Statements and Access to Information.

                  (a) Financial Statements. The Company shall deliver to each
Stockholder who holds more than 5% of the then outstanding shares of Common
Stock:

                        (i) within 60 days after the end of each quarterly
accounting period in each fiscal year of the Company, unaudited consolidated
statements of income and cash flows of the Company and its Subsidiaries for such
quarterly period and unaudited consolidated balance sheets of the Company and
its Subsidiaries as of the end of such quarterly period. Such financial
statements shall be prepared in accordance with generally accepted accounting
principles, consistently applied, subject to the absence of footnote disclosures
and to normal year-end adjustments; and

                        (ii) within 120 days after the end of each fiscal year
of the Company, audited consolidated statements of income and cash flows of the
Company and its Subsidiaries for such fiscal year, and audited consolidated
balance sheets of the Company and its Subsidiaries as of the end of such fiscal
year. Such financial statement shall be prepared in accordance with generally
accepted accounting principles, consistently applied.

                  (b) Access to Information. The Company shall permit any
Stockholder who holds more than 10% of the then outstanding shares of Common
Stock and its representatives (including, without limitation, its legal counsel,
accountants and governmental authorities to which it is subject), during normal
business hours and such other times as any such holder may reasonably request,
to (i) visit and inspect any of the properties of the Company and its
Subsidiaries, (ii) examine the corporate and financial records of the Company
and its Subsidiaries and make


                                    - 14 -
   15

copies thereof or extracts therefrom and (iii) discuss the affairs, finances and
accounts of any such entities with any of the executive officers of the Company.

                  (c) Other Information. Prior to the consummation of a
Qualified Public Offering, so long as any BT Investor owns at least 5% of the
outstanding shares of Common Stock, the Company shall, with reasonable
promptness, deliver to such BT Investor who own Stockholder Shares (and not any
of their respective assigns) copies of any previously prepared financial data or
other previously prepared written information concerning the Company and its
Subsidiaries that such BT Investor (and not any of its assigns) may reasonably
request.

            7. Legend; Additional Restriction on Transfer.

                  (a) Each certificate or instrument evidencing Stockholder
Shares and each certificate or instrument issued in exchange for or upon the
Transfer of any Stockholder Shares (if such securities remain Stockholder Shares
(as defined herein) after such Transfer) shall be stamped or otherwise imprinted
with a legend in substantially the following form:

            "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
            REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"),
            AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE
            REGISTRATION STATEMENT UNDER THE ACT OR AN EXEMPTION FROM
            REGISTRATION THEREUNDER. THE TRANSFER OF THE SECURITIES REPRESENTED
            BY THIS CERTIFICATE IS SUBJECT TO A SHAREHOLDERS AGREEMENT DATED AS
            OF FEBRUARY 26, 1998, AS MAY BE AMENDED FROM TIME TO TIME, BY AND
            AMONG THE ISSUER AND CERTAIN OF THE ISSUER'S STOCKHOLDERS. A COPY OF
            SUCH SHAREHOLDERS AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE
            ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST."

The legend set forth above regarding the Shareholders Agreement shall be removed
from the certificates evidencing any securities which cease to be Stockholder
Shares. Upon the request of any holder of Stockholder Shares, the Company shall
remove the Securities Act legend set forth above from the certificate or
certificates for such Stockholder Shares; provided, that such Stockholder Shares
are eligible for sale pursuant to Rule 144(k) (or any similar rule or rules then
in effect) under the Securities Act.

                  (b) Unless waived by the Company, no Stockholder may Transfer
any Stockholder Shares (except pursuant to an effective registration statement
under the Securities Act) without first delivering to the Company an opinion of
counsel reasonably acceptable in form and substance to the Company (which
counsel will be reasonably acceptable to the Company) that registration under
the Securities Act is not required in connection with such Transfer. If such


                                    - 15 -
   16

opinion of counsel reasonably acceptable in form and substance to the Company
further states that no subsequent Transfer of such Stockholder Shares will
require registration under the Securities Act, the Company will promptly upon
such Transfer deliver new certificates for such securities which do not bear the
Securities Act legend set forth in Section 7(a).

            8. Transfers in Violation of Agreement. Any Transfer or attempted
Transfer of any Stockholder Shares in violation of any provision of this
Agreement shall be null and void, and the Company shall not record such Transfer
on its books or treat any purported transferee of such Stockholder Shares as the
owner of such securities for any purpose.

            9. Preemptive Rights.

                  (a) If at any time prior to the consummation of a Qualified
Public Offering the Company wishes to issue any Common Stock or any options,
warrants or other rights to acquire Common Stock or any notes or other
securities convertible or exchangeable into Common Stock (all such Common Stock
and other rights and securities, collectively, the "Equity Equivalents") to any
Person or Persons, the Company shall promptly deliver a notice of intention to
sell (the "Company's Notice of Intention to Sell") to each Investor setting
forth a description and the number of the Equity Equivalents proposed to be
issued and the proposed purchase price and terms of sale. Upon receipt of the
Company's Notice of Intention to Sell, each Investor shall have the right to
elect to purchase, at the price and on the terms stated in the Company's Notice
of Intention to Sell, a number of the Equity Equivalents equal to the product of
(i) such Investor's proportionate ownership of the outstanding shares of Common
Stock (calculated on a fully-diluted basis assuming all holders of then
outstanding warrants, options and convertible securities of the Company which
are in the money had converted such convertible securities or exercised such
warrants or options immediately prior to the taking of the record of the holders
of Common Stock for the purpose of determining whether they are entitled to
receive such offer) held by all Persons multiplied by (ii) the number of Equity
Equivalents proposed to be issued (as described in the applicable Company's
Notice of Intention to Sell). Such election shall be made by the electing
Investor by written notice to the Company within fifteen (15) business days
after receipt by such Investor of the Company's Notice of Intention to Sell (the
"Acceptance Period"). In the event that any Equity Equivalents proposed to be
issued at any time as contemplated by this Section 9 are either voting
securities or securities which are convertible, exercisable or exchangeable for
voting securities and for any reason one or more of the Investors determines in
its sole discretion that it would be detrimental to such Investor or its
Affiliates to purchase such Equity Equivalents as provided hereby, then the
Company shall make available to any such Investor an amount of alternative
securities equal to the amount of such Equity Equivalents as such Investor has
elected to purchase pursuant to the terms hereof which are identical to such
Equity Equivalents in all respects except for the fact that such alternate
securities shall be non-voting securities or convertible, exercisable or
otherwise exchangeable for non-voting securities (the "Alternative Securities")
upon such terms and conditions as such Investor may request.

                  (b) To the extent an effective election to purchase has not
been received from an Investor pursuant to subsection (a) above in respect of
the Equity Equivalents proposed to be issued pursuant to the applicable
Company's Notice of Intention to Sell, the Company may, at its election, during
a period of one hundred and twenty (120) days following the expiration of the
applicable Acceptance Period, issue and sell the remaining Equity Equivalents to
be issued and sold


                                    - 16 -
   17

to any Person at a price and upon terms not more favorable to such Person than
those stated in the applicable Company's Notice of Intention to Sell; provided,
however, that failure by an Investor to exercise its option to purchase with
respect to one issuance and sale of Equity Equivalents shall not affect its
option to purchase Equity Equivalents in any subsequent offering, sale and
purchase. In the event the Company has not sold any Equity Equivalents covered
by a Company's Notice of Intention to Sell, or entered into a binding agreement
to sell such Equity Equivalents, within such one hundred and twenty (120) day
period, the Company shall not thereafter issue or sell such Equity Equivalents,
without first offering such Equity Equivalents to each Investor in the manner
provided in this Section 9.

                  (c) If an Investor gives the Company notice, pursuant to the
provisions of this Section 9, that such Investor desires to purchase any Equity
Equivalents or Alternative Securities, payment therefor shall be by check or
wire transfer of immediately available funds, against delivery of the securities
(which securities shall be issued free and clear of any liens or encumbrances)
at the executive offices of the Company at the closing dated fixed by the
Company for the sale of all such Equity Equivalents. In the event that any
proposed sale is for a consideration other than cash, such Investors may pay
cash in lieu of all (but not part) of such other consideration, in the amount
determined reasonably and in good faith by the Board to represent the fair value
of such consideration other than cash.

                  (d) The preemptive rights contained in this Section 9 shall
not apply to (i) the issuance of shares or units of Equity Equivalents as a
stock dividend or upon any subdivision, split or combination of the outstanding
shares of Common Stock; (ii) the issuance of Equity Equivalents upon conversion,
exchange or redemption of any outstanding convertible or exchangeable
securities; (iii) the issuance of Equity Equivalents upon exercise of any
outstanding options or warrants; or (iv) the issuance of Equity Equivalents to
any employee or director of the Company or any of its subsidiaries.

                  (e) The provisions of this Section 9 shall terminate upon the
consummation of a Qualified Public Offering.

            10. Amendment and Waiver. No modification, amendment or waiver of
any provision of this Agreement shall be effective against the Company or the
Stockholders unless such modification, amendment or waiver is approved in
writing by, respectively, the Company or the holders of 75% of the Stockholder
Shares; provided, that no amendment shall be effective without the consent of a
Stockholder to the extent that such amendment would adversely affect the rights
or obligations of such Stockholder hereunder in any material respect. The
failure of any party to enforce any of the provisions of this Agreement shall in
no way be construed as a waiver of such provisions and shall not affect the
right of such party thereafter to enforce each and every provision of this
Agreement in accordance with its terms. Each Stockholder shall remain a party to
this Agreement only so long as such person is the holder of record of
Stockholder Shares.

            11. Severability. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Agreement shall be
reformed, construed and enforced


                                    - 17 -

in such jurisdiction as if such invalid, illegal or unenforceable provision had
never been contained herein.

            12. Entire Agreement. Except as otherwise expressly set forth
herein, this document embodies the complete agreement and understanding among
the parties hereto with respect to the subject matter hereof and supersedes and
preempts any prior understandings, agreements or representations by or among the
parties, written or oral, which may have related to the subject matter hereof in
any way.

            13. Termination. This Agreement will automatically terminate and be
of no further force or effect immediately after the consummation of an Approved
Sale.

            14. Successors and Assigns. Except as otherwise provided herein,
this Agreement shall bind and inure to the benefit of and be enforceable by the
Company and its successors and assigns and the Stockholders and any subsequent
holders of Stockholder Shares and the respective successors, heirs and assigns
of each of them, so long as they hold Stockholder Shares.

            15. Counterparts. This Agreement may be executed in separate
counterparts each of which shall be an original and all of which taken together
shall constitute one and the same agreement.

            16. Remedies. The parties hereto shall be entitled to enforce their
rights under this Agreement specifically to recover damages by reason of any
breach of any provision of this Agreement and to exercise all other rights
existing in their favor. The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this
Agreement and that the Company and any Stockholder may in his, hers, or its sole
discretion apply to any court of law or equity of competent jurisdiction for
specific performance and/or injunctive relief (without posting a bond or other
security) in order to enforce or prevent any violation of the provisions of this
Agreement.

            17. Notices. All notices, demands or other communications to be
given or delivered under or by reason of the provisions of this Agreement will
