               any shares of its Common Stock (including any such
               reclassification in connection with a consolidation or merger in

         then the Option Shares immediately prior to such action shall be
         adjusted to apply to the aggregate number and kind of shares of Common
         Stock (or such shares of capital stock other than Common Stock) of the
         Company that the Company would have owned immediately following such
         action if the Company had exercised the Option immediately prior to
         such action.

               (b) The adjustment shall become effective on the record date in

delivered by the Stockholder and constitutes a valid and binding agreement of
the Stockholder, enforceable against the Stockholder in accordance with its
terms, except (i) as limited by applicable bankruptcy, insolvency,

the terms of any contract, agreement, obligation, commitment, license,
indenture, mortgage, deed of trust, loan or credit agreement or any other
agreement or instrument to which the Stockholder is a party or (ii) any
judgment, decree, order, statute, rule or regulation of any federal, state or
local government or agency applicable to the Stockholder.

         10. Representations and Warranties of the Company; Transfers. The
Company hereby represents and warrants to the Stockholder, as of the date hereof

(i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium,
and other laws of general application affecting enforcement of creditors' rights
generally, and (ii) as limited by laws relating to the availability of specific
performance, injunctive relief, or other equitable remedies. The Company will

warranty or any material omission made by the Stockholder in or pursuant to this
Agreement, and (ii) any breach or default in the performance by the Stockholder
of any of the obligations to be performed by the Stockholder hereunder. For

other damages, including without limitation, reasonable attorneys' fees and
other costs and expenses reasonably incurred in investigating or attempting to
avoid same, in opposing the imposition of the same, and/or in enforcing this
indemnity. The Stockholder shall obtain the prior written consent of the
Company, which shall not be unreasonably withheld, before ceasing to defend
against such claim or entering into any settlement, adjustment, or compromise of
such claim unless such settlement, adjustment, or compromise involves only the
payment of monetary consideration by the Stockholder and does not involve any
admission of fact that might have a material adverse effect on the future
business or operations of the Company or that might reasonably prejudice the
Company in subsequent or other litigation. The Stockholder shall reimburse the
Company on demand for any payment made or damages sustained by the Company at
any time after a Closing, whether based upon the judgment of any court of
competent jurisdiction, pursuant to a bona fide compromise or settlement of
claims, demands or actions, or otherwise in respect of any Indemnified Damages.

hereby represents and warrants to the Company as follows, as of the date hereof

charges, pledges or restrictions on transfer of any nature whatsoever
(collectively, "Encumbrances"), with the exception of restrictions of transfer
set forth in the Registration Rights Agreement, dated September 22, 1999,
between the Company and certain stockholders of the Company, including the
Stockholder. Other than this Agreement, there is no subscription, option,
warrant, call, right, agreement or commitment relating to the sale, delivery or
transfer by either of them of the Option Shares. Upon the sale of the Option
Shares to the Company at a Closing, the Stockholder will transfer to the Company
the entire legal and beneficial interest in all Option Shares being delivered at
such Closing, free and clear of any Encumbrances. The Stockholder is not a party
to any agreement or understanding with respect to the voting, control or
beneficial ownership of the Option Shares, nor is a proxy in effect for any of
the Option Shares.

               (b) This Agreement has been duly and validly executed and
delivered by the Stockholder and constitutes a valid and binding agreement of
the Stockholder, enforceable against the Stockholder in accordance with its
terms, except (i) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium, and other laws of general application affecting
enforcement of creditors' rights generally, and (ii) as limited by laws relating
to the availability of specific performance, injunctive relief, or other
equitable remedies.

               (c) No consent, approval, order or authorization of, or
registration, qualification, designation, declaration or filing with, any
federal, state or local governmental authority on the part of the Stockholder is
required in connection with the consummation of the transactions contemplated by
this Agreement.

               (d) The execution, delivery and performance of this Agreement
does not and will not violate (i) with or without notice or the lapse of time,
the terms of any contract, agreement, obligation, commitment, license,
indenture, mortgage, deed of trust, loan or credit agreement or any other
agreement or instrument to which the Stockholder is a party or (ii) any
judgment, decree, order, statute, rule or regulation of any federal, state or
local government or agency applicable to the Stockholder.

         10. Representations and Warranties of the Company; Transfers. The
Company hereby represents and warrants to the Stockholder, as of the date hereof
and each Closing, that this Agreement has been duly and validly executed and
delivered by the Company and constitutes a valid and binding agreement of the
Company, enforceable against the Company in accordance with its terms, except
(i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium,
and other laws of general application affecting enforcement of creditors' rights
generally, and (ii) as limited by laws relating to the availability of specific
performance, injunctive relief, or other equitable remedies. The Company will
not transfer, assign or pledge this Agreement in a manner which violates the
Securities Act of 1933 or any other applicable laws.

         11. Indemnification. The Stockholder hereby agrees to indemnify, defend
and hold harmless the Company against and in respect of any and all Indemnified
Damages (as defined below) that result to the Company from (i) any breach or
inaccuracy of any representation or

                                       4
<PAGE>   5

warranty or any material omission made by the Stockholder in or pursuant to this
Agreement, and (ii) any breach or default in the performance by the Stockholder
of any of the obligations to be performed by the Stockholder hereunder. For
purposes of this Section 11, the term "Indemnified Damages" means any and all
claims, actions, demands, losses, costs, expenses, liabilities, penalties, and
other damages, including without limitation, reasonable attorneys' fees and
other costs and expenses reasonably incurred in investigating or attempting to
avoid same, in opposing the imposition of the same, and/or in enforcing this
indemnity. The Stockholder shall obtain the prior written consent of the
Company, which shall not be unreasonably withheld, before ceasing to defend
against such claim or entering into any settlement, adjustment, or compromise of
such claim unless such settlement, adjustment, or compromise involves only the
payment of monetary consideration by the Stockholder and does not involve any
admission of fact that might have a material adverse effect on the future
business or operations of the Company or that might reasonably prejudice the
Company in subsequent or other litigation. The Stockholder shall reimburse the
Company on demand for any payment made or damages sustained by the Company at
any time after a Closing, whether based upon the judgment of any court of
competent jurisdiction, pursuant to a bona fide compromise or settlement of
claims, demands or actions, or otherwise in respect of any Indemnified Damages.
