         directors of any Subsidiary of the Company shall consist of the same
         number of directors and shall have the same composition as the Board of
         Directors as set forth in clauses (a) and (b) above. The provisions of
         this Section 2.1 in respect of election of designees, removal,
         vacancies, and costs and expenses shall apply equally to the board of
         directors of any Subsidiary of the Company.

                  (g)      Additional Representatives at Board Meetings.
         Notwithstanding the preceding provisions of this Section 2.1, so long
         as MacKay Shields has the Minimum MacKay Shields Ownership, CM-III has
         the Minimum CM-III Ownership or TCW has the Minimum TCW Ownership, each
         of MacKay Shields, CM-III and TCW shall have the right to designate one
         representative to attend all meetings of the Board of Directors of the
         Company as an observer. For avoidance of doubt, such representative
         shall not be deemed to be a member of the Board of Directors, shall not
         have any voting rights and shall not be entitled to any compensation or
         reimbursement of costs and expenses by the Company in connection with
         attending meetings of the Board of Directors of the Company.

         2.2      Director Compensation.

         the Board of the Directors of the Company or committee meetings of the
         Board of the Directors of the Company.

                  (b)      Stock Compensation. On the date hereof, the Company
         shall, pursuant to the Plan, issue to each member of the Board of
         Directors of the Company that is not an officer of the Company 200,000
         shares of Common Stock representing 0.25% of the Company's Common Stock

         2.4      Special Stockholder Actions.  Except as set forth below, all
matters to be determined by the stockholders of the Company and any of its

                                       8

                                   ARTICLE III
                             TRANSFERS OF SECURITIES

         3.1      Preemptive Rights.

                  (a)      Applicability; Offer Notice. Prior to a Qualified
         Public Offering, if the Company proposes to issue or sell to any person
         (the "Proposed Purchaser") any Common Stock or any Common Stock
         Equivalents (collectively, the "Offered Securities"), the Company
         shall, no later than 30 days prior to the consummation of such
         transaction (a "Preemptive Rights Transaction"), give written notice
         (the "Offer Notice") to each Management Stockholder and each 5%
         Stockholder of the proposed Preemptive Rights Transaction. The Offer
         Notice shall (i) describe the proposed Preemptive Rights Transaction,
         (ii) identify the Proposed Purchaser, and (iii) contain an offer (the
         "Preemptive Rights Offer") to sell to each such Management Stockholder
         or 5% Stockholder who certifies (to the reasonable satisfaction of the
         Company) that such holder is an Accredited Investor (an "Accredited
         Offeree"), at the same price and for the same consideration to be paid
         by the Proposed Purchaser, all or part of such Accredited Offeree's pro
         rata portion of the Offered Securities (which shall be the percentage
         ownership of the Common Stock on a fully diluted basis Beneficially
         Owned by such holder, excluding, for the purposes of such calculation,
         any shares of Common Stock issuable upon exercise of any Common Stock
         Equivalents granted pursuant to any employee, officer, or director
         benefit plan or arrangement). In the event of any sale or sales of
         Offered Securities to one or more Accredited Investors, the number of
         Offered Shares which may be sold to the Proposed Purchaser shall be
         such number as was set forth in the Offer Notice minus the aggregate
         number of Offered Shares so sold to Accredited Investors. If any
         Management Stockholder or 5% Stockholder fails to accept such offer by
         written notice to the Company 15 days after its receipt of the Offer
         Notice, then the Company may proceed with the issue or sale of the
         Offered Securities described in the Offer Notice (but subject to the
         provisions of the preceding sentence hereof) free of any right on the
         part of such Management Stockholder or 5% Stockholder under this
         Section 3.1(a) in respect thereof.

                  (b)      Exceptions to Preemptive Rights. Section 3.1(a) shall
         not apply to issuances or sales of Common Stock or Common Stock
         Equivalents (i) pursuant to the Management Compensation Plans, (ii)
         upon exercise of any Common Stock Equivalent that, when issued, was
         subject to or exempt from the preemptive rights under Section 3.1(a),
         (iii) to providers of financing to the Company or any of its
         Subsidiaries where such issuance or sale is, in whole or in part, made
         as consideration for such financing (e.g., as an "equity kicker" in
         such financing) and (iv) to third-party sellers (who are not Affiliates
         of the Company) in connection with acquisitions made by the Company or
         any of its Subsidiaries.

                                       9



                  (c)      Units. If any issuances or sales of any class of
         Common Stock or Common Stock Equivalents are made as a unit with any
         other security of the Company or its Subsidiaries, the preemptive
         rights under Section 3.1(a) shall be applicable to the entire unit
         rather than only the Common Stock or Common Stock Equivalent included
         in the unit.

         3.2      Right of First Offer.

                  (a)      Applicability; Transferor's Notice. Prior to a
         Qualified Public Offering and so long as MacKay Shields has the Minimum
         MacKay Shields Ownership, CM-III has the Minimum CM-III Ownership or
         TCW has the Minimum TCW Ownership (unless waived by each of MacKay
         Shields, CM-III and TCW, as hereinafter provided), if a Right of First
         Offer Selling Stockholder (each, a "Transferor") desires to Transfer (a
         "Right of First Offer Proposed Transfer") for value any shares of
         Common Stock or New Warrants (for purposes of this Article III, and
         individually or collectively, "Shares") to any person (other than by
         Registered Sale or Permitted Transfer), the Transferor shall give
         written notice (the "Transfer Notice") to the Company and the 5%
         Stockholders (the "Option Holders") of such Right of First Offer
         Proposed Transfer. The Transfer Notice shall (i) specify the number of
         shares of Common Stock and New Warrants to be transferred, the
         consideration to be received therefor, and the other material terms on
         which the Transferor proposes to Transfer the shares of Common Stock
         and New Warrants and (ii) contain the offer described in Section
         3.2(b).

                  (b)      Option Offers.

                           (i)      The Transferor shall offer to sell (the
                  "First Option") all such shares to the Company for the same
                  consideration as specified in the Transfer Notice, consisting
                  of (A) cash equal to the amount of cash and (B) if applicable,
                  non-cash consideration (other than consideration having a fair
                  market value equal to the fair market value of such non-cash
                  consideration) specified in the Transfer Notice. The decision
                  whether or not the Company will accept the First Option shall
                  be made by the Board of Directors and the Company shall give
                  the Transferor written notice of such determination on or
                  prior to the tenth Business Day (the "Election Period") after
                  receipt of the Transfer Notice. If the Company (A) fails to
                  notify the Transferor in writing on or prior to the tenth
                  Business Day after receipt of the Transfer Notice that it
                  elects to accept the First Option or (B) by written notice
                  within such ten-day period rejects the First Option in whole
                  or part, then the Transferor shall offer to sell (the "Second
                  Option") the Shares not so purchased to the other Option
                  Holders for the same consideration; provided, however, that
                  the Transferor shall not be obligated to offer such Shares to
                  any Holder who is not an Accredited Investor.

                           (ii)     The other Option Holders may purchase the
                  Shares so offered in proportion to the number of shares of
                  Common Stock on a fully-diluted basis Beneficially Owned by
                  each such Option Holder who desires to participate in the
                  purchase of such Shares pursuant to the Second Option bears to
                  the aggregate number of shares of Common Stock on a
                  fully-diluted basis Beneficially Owned by all such Option
                  Holders who desire to participate in the purchase of such
                  Shares pursuant to the Second Option.

                           (iii)    If the First Option and/or the Second
                  Option, as the case may be, is accepted in a manner such that
                  all Shares covered by the Transfer Notice are to be purchased,
                  the Transferor shall Transfer all such shares (free of all
                  liens and encumbrances except this Agreement, all as
                  reasonably determined by the Company) to

                                       10



                  the respective purchasers thereof within 15 Business Days
                  following the receipt by the Option Holders of the Transfer
                  Notice against delivery by the purchaser(s) of the
                  consideration payable to the Transferor as set forth in the
                  Transfer Notice; provided, however, that if the HSR Act is
                  applicable to the First Option or the Second Option, such date
                  shall be extended to the date that is five Business Days after
                  the date the applicable HSR Act waiting period expires or is
                  terminated.

                           (iv)     Unless, through exercise of the First Option
                  and/or Second Option, all the Shares proposed to be
                  Transferred in the Transfer Notice are to be acquired by the
                  Company and/or one or more other Option Holders, the
                  Transferor shall be permitted to transfer the Shares on the
                  terms set forth in the Transfer Notice (with no additional
                  terms more favorable to the transferee than those offered to
                  the Option Holders, including, without limitation, at a price
                  no less than the price offered to the Option Holders);
                  provided, however, that such Transfer shall occur no later
                  than 180 days following the Election Period or five days after
                  the expiration or termination of any waiting period applicable
                  to the transfer pursuant to the HSR Act, whichever is later,
                  on the terms set forth in the Transfer Notice. If such
                  Transfer does not occur within such 180-day period, or such
                  five-day period after the expiration or termination of any HSR
                  Act waiting period, then the Shares shall be re-offered
                  (without obligation to purchase) to the Company and the other
                  Option Holders under this Section 3.2 prior to any subsequent
                  Transfer pursuant to the terms of this Section 3.2.

                  (c)      The provisions of this Section 3.2 shall be subject
         to the terms and conditions of the second paragraph of Section 3.4(a).

         3.3      Drag Along Rights.

                  (a)      Applicability. The Board of Directors of the Company
         by a Special Director Vote shall have the right, prior to the
         occurrence of a Qualified Public Offering, to cause a sale of the
         Company or any of its Subsidiaries through a sale of shares of Common
         Stock and/or Common Stock Equivalents, merger, recapitalization, sale
         of substantially all of the assets of the Company and its Subsidiaries,
         taken as a whole, or other similar transaction (a "Sale of the
         Company"), and to cause all Stockholders to consent to, approve and
         participate in a Sale of the Company; provided, however, that (i) all
         Stockholders receive the same consideration on a per share basis, (ii)
         the identity of such purchaser is approved (which approval shall not be
         unreasonably withheld) by MacKay Shields, CM-III and TCW; provided that
         MacKay Shields has the Minimum MacKay Shields Ownership, CM-III has the
         Minimum CM-III Ownership and TCW has the Minimum TCW Ownership, as the
         case may be, and (iii) such purchaser is not MacKay Shields, CM-III or
         TCW or any 5% Stockholder or any Affiliate of the foregoing.

                  (b)      Notice of Sale of the Company. The Board of
         Directors, on behalf of the Company, shall give the Stockholder at
         least 30 days' prior written notice of any such proposed Sale of the
         Company. If the Board of Directors elects to cause a Sale of the
         Company under this Section 3.3, the Stockholders shall take such
         actions as may be reasonably required and otherwise cooperate in good
         faith with the Board of Directors in connection with consummating the
         Sale of the Company (including, without limitation, the voting of any
         Common Stock, Common Stock Equivalents or other voting capital stock of
         the Company to approve such Sale of the Company). At the closing of
         such Sale of the Company, each Stockholder shall deliver certificates
         for all shares of Common Stock and all Common Stock Equivalents to be
         sold by such Stockholder, duly endorsed for transfer, with the
         signature guaranteed, to the purchaser against payment of the
         appropriate purchase price.

                                       11



                  3.4      Tag Along Rights.

                  (a)      Applicability. Prior to a Qualified Public Offering,
         but other than with respect to a Registered Sale, and so long as MacKay
         Shields has the Minimum MacKay Shields Ownership, CM-III has the
         Minimum CM-III Ownership or TCW has the Minimum TCW Ownership, if any
         5% Stockholder (a "Tag-Along Selling Stockholder") desires to effect a
         sale of Shares (other than a Permitted Transfer) (a "Tag-Along
         Transaction"), then at least 30 days prior to the closing of such
         Tag-Along Transaction, the Tag-Along Selling Stockholder shall make an
         offer (the "Participation Offer") to each other 5% Stockholder
         (together with the Permitted Transferees of such stockholder, the
         "Tag-Along Participating Stockholders") to include in the proposed
         Tag-Along Transaction a number of Shares equal to the product of (i)
         the quotient determined by dividing the percentage of Shares (as
         determined on a fully-diluted basis) owned by the Tag-Along
         Participating Stockholder, by the aggregate percentage of Shares (as
         determined on a fully-diluted basis) owned by all Tag-Along
         Participating Stockholders and all Tag-Along Selling Stockholders in
         such sale, times (iii) the number of Shares proposed to be sold by the
         Tag-Along Selling Stockholder; provided, however, that if the
         consideration to be received by the Tag-Along Participating
         Stockholders includes any securities, only Tag-Along Participating
         Stockholders who have certified to the reasonable satisfaction of the
         Company that they are Accredited Investors shall be entitled to
         participate in such Transfer, unless the transferee consents otherwise.
         The Tag-Along Participating Stockholders shall give the Tag-Along
         Selling Stockholder written notice of their intent to participate in
         such Tag-Along Transaction on or prior to the tenth Business Day after
         receipt of the Participation Offer.

                  Solely for purposes of determining whether Metropolitan Life
         Insurance Company ("MetLife") may be treated as a Tag-Along
         Participating Stockholder, MetLife shall be deemed to be the Beneficial
         Owner also of the Shares Beneficially Owned by TCW; provided, however,
         that any pro rata participation of MetLife in any Tag-Along Transaction
         or in any Right of First Offer Proposed Transfer shall be based solely
         on the amount of shares of Common Stock of which MetLife shall be the
         Beneficial Owner (and shall not include, and shall not be duplicative
         with, any shares of Common Stock of which TCW is the Beneficial Owner);
         provided, further, however, that for purposes of determining any pro
         rata participation of any other Stockholder in any Tag-Along
         Transaction or Right of First Offer Proposed Transfer where Shares are
         Beneficially Owned by more than one person or entity, such pro rata
         participation shall be determined without duplication of Beneficial
         Ownership.

                  (b)      Participation Offer. The Participation Offer shall
         describe the terms and conditions of the proposed Tag-Along Transaction
         and shall be conditioned upon (i) the consummation of the transactions
         contemplated in the Participation Offer with the transferee named
         therein, and (ii) each Tag-Along Participating Stockholders' execution
         and delivery of all agreements and other documents as the Tag-Along
         Selling Stockholders are required to execute and deliver in connection
         with such Tag-Along Transaction; provided, however, that the Tag-Along
         Participating Stockholders shall not be required to make any
         representations or warranties with respect to other Tag-Along
         Participating Stockholders as to (A) such other Tag-Along Participating
         Stockholders' ownership of their Shares to be sold or transferred, (B)
         such other Tag-Along Participating Stockholders' power and authority to
         effect such transfer, and (C) matters pertaining to compliance with
         securities laws by other Tag-Along Participating Stockholders. If any
         Tag-Along Participating Stockholder accepts the Participation Offer,
         the Tag-Along Selling Stockholder shall reduce, to the extent
         necessary, the number of Shares it otherwise would have sold in the
         proposed transfer so as to permit those Tag-Along Participating
         Stockholders who have accepted the Participation Offer to sell the
         number of Shares that they are entitled to sell under this Section 3.4,
         and the Tag-Along Selling Stockholder and such Tag-Along

                                       12



         Participating Stockholders shall transfer the number of Shares
         specified in the Participation Offer to the proposed transferee in
         accordance with the terms of such transfer set forth in the
         Participation Offer.

         3.5      Certain Events Not Deemed Transfers. Sections 3.2, 3.3 and 3.4
shall not apply with respect to any Permitted Transfers.

         3.6      Transfer and Exchange. When Securities are presented to the
Company with a request to register the transfer of such Securities or to
exchange such Securities for Securities of other authorized denominations, the
Company shall register the transfer or make the exchange as requested if the
requirements of this Agreement for such transaction are met; provided, however,
that the Securities surrendered for transfer or exchange shall be duly endorsed
or accompanied by a written instrument of transfer in form reasonably
satisfactory to the Company, duly executed by the holder thereof or its attorney
and duly authorized in writing. No service charge shall be made for any
registration of transfer or exchange, but the Company, may require payment of a
sum sufficient to cover any transfer tax or similar governmental charge payable
in connection therewith.

         3.7      Replacement Securities. If a mutilated Security is surrendered
to the Company or if the holder of a Security claims and submits an affidavit or
other evidence, reasonably satisfactory to the Company, to the effect that the
Security has been lost, destroyed, or wrongfully taken, the Company shall issue
a replacement Security if the Company's requirements are met. If required by the
Company, such holder must provide an indemnity bond, or other form of indemnity,
sufficient in the judgment of the Company to protect the Company against any
loss that may be suffered. The Company may charge such holder for its reasonable
out-of-pocket expenses in replacing a Security that has been mutilated, lost,
destroyed, or wrongfully taken.

                                   ARTICLE IV
                             LIMITATION ON TRANSFERS

         4.1      Restrictions on Transfer. No Securities shall be Transferred
before satisfaction of (i) the conditions specified in Sections 4.1, 4.2, and
4.3, which conditions are intended to ensure compliance with the provisions of
the Securities Act in respect of the Transfer of any Security and (ii) if
applicable, Article III. No such Transfer shall result in the Company being
subject to registration pursuant to the Investment Company Act of 1940, as
amended.

         Any purported Transfer in violation of this Article IV and/or, if
applicable, Article III shall be void ab initio and of no force or effect other
than Transfers subject to and in compliance with Sections 3.2, 3.3, and 3.4 and
other than Transfers to the public pursuant to an effective registration
statement or Transfers to the public pursuant to Rule 144 under the Securities
Act otherwise permitted hereunder. Each Stockholder will cause any proposed
transferee (including Permitted Transferees) of any Security or any interest
therein held by it to agree to take and hold such securities subject to the
provisions and upon the conditions specified in this Agreement.

         4.2      Restrictive Legends.

                  (a)      Securities Act Legend. Except as otherwise provided
         in Section 4.4, each Security held by a Stockholder, and each Security
         issued to any subsequent transferee of such Security, shall bear a
         legend in substantially the following form:

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933,

                                       13



                  AS AMENDED, NOR PURSUANT TO THE SECURITIES OR "BLUE SKY" LAWS
                  OF ANY STATE. SUCH SECURITIES MAY NOT BE OFFERED, SOLD,
                  TRANSFERRED, PLEDGED, HYPOTHECATED, OR OTHERWISE ASSIGNED,
                  EXCEPT PURSUANT TO (i) A REGISTRATION STATEMENT IN RESPECT OF
                  SUCH SECURITIES THAT IS EFFECTIVE UNDER SUCH ACT, (ii) RULE
                  144 UNDER SUCH ACT, OR (iii) ANY OTHER EXEMPTION FROM
                  REGISTRATION UNDER SUCH ACT.

                  (b)      Other Legends. Each Security held by a Stockholder,
         and each Security issued to any subsequent transferee of such Security,
         shall bear a legend in substantially the following form:

                  THIS SECURITY IS SUBJECT TO RESTRICTIONS ON TRANSFER, VOTING,
                  AND OTHER TERMS AND CONDITIONS SET FORTH IN THE STOCKHOLDERS
                  AGREEMENT DATED AS OF OCTOBER [ ], 2003, A COPY OF WHICH MAY
                  BE OBTAINED FROM THE COMPANY AT ITS PRINCIPAL EXECUTIVE
                  OFFICES.

         4.3      Notice of Proposed Transfers. Prior to any Transfer or
attempted Transfer of any Security by any 5% Stockholder (other than Transfers
subject to Sections 3.2, 3.3, or 3.4 or Transfers described in Section 3.5 or
Transfers pursuant to a Registered Sale), such 5% Stockholder shall (i) give ten
days' prior written notice to the Company of such holder's intention to effect
such Transfer, describing the manner and circumstances of the proposed Transfer,
and (ii) either (A) provide to the Company an opinion reasonably satisfactory to
the Company from counsel who shall be reasonably satisfactory to the Company (or
supply such other evidence reasonably satisfactory to the Company) that the
proposed Transfer of such Security may be effected without registration under
the Securities Act, or (B) certify to the Company that the holder reasonably
believes the proposed transferee is a "qualified institutional buyer" and that
such holder has taken reasonable steps to make the proposed transferee aware
that such holder may rely on Rule 144A under the Securities Act in effecting
such Transfer. After receipt of the notice of Transfer and opinion (if
required), the Company shall, within five days thereafter, so notify the holder
of such Security and such holder shall thereupon be entitled to Transfer such
Security in accordance with the terms of the notice. Each Security issued upon
such Transfer shall bear the restrictive legend set forth in Section 4.2(a),
unless in the opinion of such counsel such legend is not required in order to
ensure compliance with the Securities Act. The holder of the Security giving the
notice of Transfer shall not be entitled to Transfer such Security until receipt
of the notice from the Company under this Section 4.3.

         4.4      Termination of Certain Restrictions. Notwithstanding the
foregoing provisions of this Article IV, the restrictions imposed by Section
4.2(a) upon the transferability of the Securities and the legend requirements of
Section 4.2(a) shall terminate as to any Security (i) when and so long as such
Security shall have been effectively registered under the Securities Act and
disposed of pursuant thereto or (ii) when the Company shall have received an
opinion of counsel reasonably satisfactory to it that such Security may be
transferred without registration thereof under the Securities Act and that such
legend may be removed. Whenever the restrictions imposed by Section 4.2(a) shall
terminate as to any Security, the holder thereof shall be entitled to receive
from the Company, at the Company's expense, a new Security not bearing the
restrictive legend set forth in Section 4.2(a).

                                       14



                                    ARTICLE V

CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT
REGARD TO ANY CHOICE OF LAW OR THE CONFLICT OF LAW PRINCIPLES THAT WOULD CAUSE
THE APPLICATION OF THE INTERNAL LAWS OF ANY STATE OTHER THAN THE STATE OF NEW
YORK.

                                       15



of the date such attempt was first made. Notwithstanding any other provision of

validity, legality, and enforceability of any such provision in every other
respect and the remaining provisions shall not in any way be affected or
impaired thereby.

has been made pursuant to the provisions of this Agreement, provisions of this
Agreement that are for the Holders' benefit as the holders of any Securities are
also for the benefit of, and enforceable by, all subsequent holders of
Securities, except as otherwise expressly provided herein. This Agreement shall
be binding upon the Company, each Stockholder, and their respective successors
and assigns.

         5.6      Termination. The provisions of this Agreement shall terminate
on the date that no Standby Purchaser owns any shares of Common Stock or any New
Warrants; provided, however, that Sections 3.1, 3.2, 3.3 and 3.4 shall terminate
upon the consummation of a Qualified Public Offering.

         5.7      No Waivers; Amendments.

                  (a)      No failure or delay on the part of the Company or any
         Stockholder in exercising any right, power, or remedy hereunder shall
         operate as a waiver thereof, nor shall any single or partial exercise
         of any such right, power, or remedy preclude any other or further
         exercise thereof or the exercise of any other right, power, or remedy.
         The remedies provided for herein are cumulative and are not exclusive
         of any remedies that may be available to the Company or any Stockholder
         at law, in equity, or otherwise.

                  (b)      Any provision of this Agreement may be amended or

         owned by the Stockholders who are parties to this Agreement and (iii)

         Minimum MacKay Shields Ownership, the Minimum CM-III Ownership or the
         Minimum TCW Ownership, as the case may be; provided, however, that no
         such amendment or waiver shall, unless signed by all of the

         number of Stockholders that shall be required for the Stockholders or
