                       PREEMPTIVE RIGHT ON COMPANY ISSUES

         SECTION 2.1. The Company will give each Investor written notice (the
"COMPANY OFFER"), of the Company's intention to sell or issue any Equity
Securities (the "COMPANY OFFERED SECURITIES"), other than an Exempt Issuance,
stating the material proposed terms of such sale or issuance and each Investor's
pro rata portion, as described below. Each Investor's pro rata portion will be
that number of Company Offered Securities equal to the product of the number of
Company Offered Securities multiplied by a fraction, the numerator of which is
the number of Shares held by such Investor (on an as converted basis) and the
denominator of which is the total number of outstanding Shares (on an as
converted basis). Such notice will include a representation to each Investor
that, to the Company's knowledge, a Person has made a bona fide offer to
consummate such Company Offer and the Company has a good faith intention to sell
such Equity Securities to such Person on the terms specified.

         SECTION 2.2. Within fifteen (15) Business Days after receipt of a
Company Offer, each Investor will give an irrevocable written notice to the
Company (an "ACCEPTANCE NOTICE") that (i) such Investor has elected to purchase
all or a specified portion of the Company Offered Securities without regard to
the other Investors' elections at the price and upon the terms specified in the
notice, or (ii) such Investor does not wish to purchase any of the Company
Offered Securities. If any Investor fails to give an Acceptance Notice by the
end of such fifteen (15) Business Day period, such Investor will be deemed to
have elected not to purchase any of the Company Offered Securities.

         SECTION 2.3. If the Investors elect to purchase, in the aggregate,
either the total or more than the total amount of Company Offered Securities,
the Company Offered Securities will be allocated as follows:

                  (a)      If any Investor elects to purchase less than its pro
         rata portion (calculated in accordance with Section 2.1) of the Company
         Offered Securities, then such Investor will be allocated the amount of
         Company Offered Securities it elected to purchase and the other
         Investors will be allocated pro rata based on their respective pro rata
         portions of the Company Offered Securities (calculated in accordance
         with Section 2.1) and will be notified of this allocation and deemed to
         have elected to purchase the balance of the Company Offered Securities
         unless any such Investor notifies the Company that it does not wish to
         purchase any Company Offered Securities allocated to it pursuant to
         this Section 2.3(a); provided, however, that no Investor will be
         obligated to purchase an amount of Company Offered Securities in excess
         of the amount set forth in its Acceptance Notice; and

                  (b)      if no Investor elects to purchase less than its pro
         rata portion (calculated in accordance with Section 2.1) of the Company
         Offered Securities, each Investor will be allocated and be deemed to
         have elected to purchase its respective portion (calculated in
         accordance with Section 2.1) of the Company Offered Securities.

         SECTION 2.4. If the Investors do not elect to purchase all of the
Company Offered Securities, the Company will have the right, exercisable not
later than ninety (90) days after expiration of the notice period set forth in
Section 2.2, to issue the Company Offered Securities not purchased by the
Investors on terms and conditions no more favorable than those set forth in the
Company Offer; provided, however, that the purchaser of the Company Offered
Securities must agree in writing to be bound by the terms of this Agreement. Any
Company Offered Securities not sold within the 90-day period must be reoffered
to the Investors pursuant to this Article II.

         SECTION 2.5. The closing of any sale or issue of Company Offered
Securities to an Investor pursuant to this Article II will take place on such
date, within a reasonable time after the date of the Acceptance Notice (subject
to extension to comply with any applicable law), as will be agreed by the
Company and such Investor. At any such closing, the Company will deliver to each
purchasing Investor certificates representing the Company Offered Securities
being issued, registered in the name of such purchasing Investor or its nominee,
against payment of the applicable purchase price.

                                   ARTICLE III

                       DRAG-ALONG RIGHT & TAG-ALONG RIGHT

         SECTION 3.1. DRAG-ALONG PROCEDURE. If the Board and the Majority
Shareholder approve a Qualified Change of Control Transaction, then the Company
or the Majority Shareholder will have the right, upon delivering written notice
describing the transaction and the material terms and conditions thereof in
reasonable detail (the "DRAG-ALONG NOTICE") to the holders of the Series G
Preferred ("SERIES G SHAREHOLDERS") to require each Series G Shareholder to
approve the Qualified Change of Control Transaction in that Series G
Shareholder's capacity as a shareholder of the Company and, if applicable, to
include in the Qualified Change of Control Transaction up to the same percentage
of that Series G Shareholder's holdings of each class of capital stock of the
Company as the percentage of the Majority Shareholder's total holdings being
sold. Any such participation by the Series G Shareholders will be on the same
terms and subject to the same conditions as are applicable to the Majority
Shareholder. As of the date that the Drag-Along Notice is delivered to each
Series G Shareholder, the Majority Shareholder's election to require that Series
G Shareholder to participate in the Qualified Change of Control Transaction will
be irrevocable and will be deemed to constitute a binding agreement of the
Majority Shareholder to include in the Qualified Change of Control Transaction
the capital stock owned by the Series G Shareholders specified in the Drag-Along
Notice. A "QUALIFIED CHANGE OF CONTROL TRANSACTION" is a transaction in which a
proposed transferee would acquire (i) Equity Securities of the Company
possessing ordinary voting power to elect a majority of the Company's Board
pursuant to merger or consolidation or recapitalization involving the Company,
or (ii) all or substantially all of the assets of the Company, either of which
in an arm's-length transaction in which the consideration per share of Series G
Preferred is at least $8.07 (as equitably adjusted to reflect stock splits,
stock dividends and similar occurrences).


                                       4

         SECTION 3.2. COOPERATION. In furtherance of the covenants in Section
3.1, each Series G Shareholder will cooperate fully with the Majority
Shareholder and the proposed transferee in any transfer of capital stock
pursuant to this Article III and will execute and deliver all documents and
instruments as the Majority Shareholder and the proposed transferee reasonably
request to effect such transfer, including appropriate and customary
representations, warranties, and indemnification provisions; provided, however,
that nothing in this Section 3.2 will operate to suspend, interfere with or
otherwise limit any rights to which such Series G Shareholders will be entitled
to pursuant to this Agreement. Each Series G Shareholder will deliver to the
proposed transferee one or more certificates, properly endorsed for transfer,
that represent the number of shares such Series G Shareholder must sell pursuant
to this Article III. The stock certificate or certificates that each Series G
Shareholder delivers will be timely delivered free and clear of any and all
liens and encumbrances; and the Majority Shareholder will instruct the proposed
transferee to remit to the Series G Shareholders that portion of the sale
proceeds to which each Series G Shareholder is entitled by reason of its
transfer of capital stock.

         SECTION 3.3. TAG-ALONG RIGHT. The Majority Shareholder may not Transfer
any of its Shares to a Bona Fide Third Party unless each other Series G
Shareholder is offered a pro rata right to participate in any such Transfer on
terms and conditions not less favorable than those applicable to the Majority
Shareholder. Each Series G Shareholder's pro rata right to participate in any
such Transfer is that Series G Shareholder's right to include in such Transfer
the same percentage of that Series G Shareholder's Shares as the percentage of
the Majority Shareholder's total holdings that the Majority Shareholder proposes
to Transfer. The provisions of this Section 3.3 will not apply to any Transfer
by the Majority Shareholder (or an Affiliate of the Majority Shareholder) to an
Affiliate of the Majority Shareholder or to any bona fide gift.

         SECTION 3.4. TAG-ALONG PROCEDURE. The Majority Shareholder will give
each Series G Shareholder written notice of the Majority Shareholder's intention
to Transfer any of its Shares to a Bona Fide Third Party stating the material
proposed terms of such Transfer. Within fifteen (15) Business Days after receipt
of the written notice described in this Section 3.4, each Series G Shareholder
will give an irrevocable written notice to the Majority Shareholder whether such
Series G Shareholder elects to participate in such Transfer at the price and
upon the terms specified in the notice. If any Series G Shareholder fails to
give written notice of its election by the end of such fifteen (15) Business Day
period, such Series G Shareholder will be deemed to have elected not to
participate.

         SECTION 3.5. COOPERATION. Each Series G Shareholder electing to
participate in a proposed Transfer by the Majority Shareholder as described in
Section 3.4 will cooperate fully with the Majority Shareholder and the proposed
transferee and will execute and deliver all documents and instruments as the
Majority Shareholder and the proposed transferee reasonably request to effect
such transfer, including appropriate and customary representations, warranties,
and indemnification provisions. Each Series G Shareholder will deliver to the
proposed transferee one or more certificates, properly endorsed for transfer,
that represent the number of shares such Series G Shareholder will Transfer
pursuant to this Article III. The stock certificate or certificates that each
Series G Shareholder delivers will be timely delivered free and clear of


                                       5
<PAGE>   6

any and all liens and encumbrances; and the Majority Shareholder will instruct
the proposed transferee to remit to the Series G Shareholders that portion of
the sale proceeds to which each Series G Shareholder is entitled by reason of
its Transfer.

                                   ARTICLE IV

                              ADDITIONAL PROVISIONS

         SECTION 4.1. TERMINATION. Unless a specific Section or Article provides
otherwise for that Section or Article, this Agreement will terminate as to each
Series G Shareholder, when that Series G Shareholder no longer holds shares of
Series G Preferred or shares of Common Stock acquired upon conversion of Series
G Preferred and, as to all Series G Shareholders, upon the closing of the
initial public offering of shares of Common Stock to the public.

         SECTION 4.2. LEGENDS. Each certificate representing any Series G
Preferred or Common Stock acquired upon conversion of Series G Preferred will be
endorsed with a legend in substantially the following form:

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
                  BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO,
                  OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION
                  THEREOF. NO SUCH SALE OR DISPOSITION MAY BE EFFECTED
                  WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED
                  THERETO OR AN OPINION OF COUNSEL SATISFACTORY TO THE
                  CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED
                  UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

         SECTION 4.3. PROHIBITED TRANSFERS. Any attempt by an Investor to

holder of such shares.
