      4. REPURCHASE OF SHARES

      (a) Repurchase Option. In the event of the Executive's termination of
employment with the Company for any reason (the date on which such termination
occurs, the "Termination Date"), the Company and the Investors shall have an
option (a "Repurchase Option"), exercisable within 90 days following the
Termination Date (the "Expiration Date"), to purchase from the Executive and his
or her Permitted Transferees, if any, any of the Executive Shares held by the
Executive at a price per share as determined pursuant to Section 4(e) below;
provided, any such repurchase of Executive Shares shall be allocated ratably
between the Common Executive Shares and Preferred Executive Shares such that for
each Common Executive Share so repurchased, a number of Preferred Executive
Shares equal to the total number of Preferred Shares held by the Executive
divided by the total number of Common Executive Shares held by the Executive
shall be purchased, in each case determined as of the Termination Date. In
connection with such Repurchase Option, the Company shall provide written notice
to the Investors promptly after the Termination Date of (i) such Executive's
termination, (ii) the number of Executive Shares subject to the Repurchase
Option, and (iii) the purchase price for each such Executive Share. Any Investor
may transfer its rights under this Section 4 to any of its Permitted
Transferees. Any Unvested Shares not repurchased hereunder prior to the
Expiration Date shall immediately become Vested Shares (provided Executive
complies with all provisions of this Section 4).

      (b) Repurchase by the Company. Within 45 days after the Termination Date,
the Company may exercise its Repurchase Option by delivery of written notice
(each, a "Repurchase Notice") to the holder or holders of Executive Shares. The
Repurchase Notice shall set forth the number of Executive Shares to be acquired
from such holder or holders of Executive Shares, and the aggregate consideration
to be paid for such Executive Shares. The number of Executive Shares to be
repurchased by the Company shall first be satisfied to the extent possible from
the Executive Shares held by the Executive at the time of delivery of the
Repurchase Notice. If the number of Executive Shares held by the Executive is
less than the total number of Executive Shares the Company has elected to
purchase, the Company shall purchase the remaining Executive Shares elected to
be purchased from the Permitted Transferee(s) of the

                                       7
<PAGE>

Executive Shares, pro rata according to the number of Executive Shares held by
such Permitted Transferee(s) on the Termination Date (determined as nearly as
practicable to the nearest share).

      (c) Repurchase by the Investor. If for any reason the Company does not
elect to purchase all of the Executive Shares pursuant to the Repurchase Option,
then the Investors shall be entitled to exercise the Repurchase Option for all
or any portion of the number of Executive Shares the Company has not elected to
purchase (the "Available Shares"). Each of the Investors shall have a right to
purchase a pro rata portion of the Available Shares based on the total number of
shares of Common Stock then held by each Investor; provided, that if any
Investor elects not to purchase its pro rata portion of the Available Shares,
the other Investor shall have the right to purchase any such remaining Available
Shares. As soon as practicable after the Company has determined that there will
be Available Shares, but in any event within 45 days after the Termination Date,
the Company shall deliver a written notice to each holder of Executive Shares
and the Investors as to the number of Executive Shares being purchased from each
such holder by the Company and each Investor and the time and place of the
closing of the transaction (which in no event shall be after the 90th day
following the Termination Date) (the "Supplemental Repurchase Notice"). At the
time the Company delivers the Supplemental Repurchase Notice to each such holder
of Executive Shares, each Investor shall also receive written notice from the
Company setting forth the number of Available Shares it has elected to purchase,
the aggregate purchase price and the time and place of the closing of the
transaction. The Repurchase Option with respect to any Executive Shares not
repurchased on or prior to the Expiration Date shall terminate (provided
Executive complies with the provisions of this Section 4).

      (d) Closing of Repurchase of Executive Shares. The purchase of Executive
Shares pursuant to this Section 4 will be closed at the Company's executive
offices at the time specified in the Supplemental Repurchase Notice. At the
closing, the purchaser or purchasers shall pay the purchase price in the manner
specified in Section 4(c) and the holder or holders of the Executive Shares
being so purchased shall deliver the certificate or certificates (or duly
executed affidavits of lost certificates in accordance with the Certificate of
Incorporation) representing any such Executive Shares to the purchaser or
purchasers or their nominees, accompanied by duly executed stock powers. Any
purchaser of Executive Shares under this Section 4 shall be entitled to receive
customary representations and warranties from such holder or holders of the
Executive Shares being so purchased regarding good title to such Executive
Shares, free and clear of any liens or encumbrances.

      (e) Repurchase Option Purchase Price. In the event of the Executive's
termination of employment with the Company for any reason other than for Cause,
the purchase price per share of the Executive Shares repurchased pursuant to
this Section 4 shall be the Fair Market Value thereof, except that the purchase
price per share of Common Executive Shares which are Unvested Shares shall be
the Original Cost thereof. In the event of the Executive's termination of
employment with the Company for Cause, the purchase price per share of (i) the
Common Executive Shares repurchased pursuant to this Section 4 shall be the
lower of the Fair Market Value thereof and Original Cost thereof and (ii) the
Preferred Executive Shares shall be the Fair Market Value thereof. For purposes
of this Section 4(e), Fair Market Value shall be determined as of the
Termination Date. The purchase price for the Executive Shares repurchased

                                       8
<PAGE>

pursuant to the Repurchase Option shall be paid by a transfer of immediately
available funds or certified check which shall be delivered to the Executive at
the closing of such purchase.

      (f) Termination of Repurchase Option. All rights and obligations created
pursuant to this Section 4 shall be extinguished upon the earlier of (i) a Sale
of the Company or (ii) the consummation of an Initial Public Offering.

(y) the Company shall have notified the Executive of its agreement to provide
such severance compensation (1) in the event of resignation, within five days

the Company or any of its Subsidiaries, on the other hand.

      9. MISCELLANEOUS.

      (a) 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,

                                       12
<PAGE>

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

      (b) Entire Agreement. Except as otherwise expressly set forth herein, this
Agreement, the Shareholders Agreement, the Common Option Agreement, the
Preferred Option Agreement and the Registration Rights Agreement embody the
complete agreement and understanding among the parties hereto with respect to
the subject matter hereof and supersede and preempt 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.

      (c) Successors and Assigns. This Agreement shall bind and inure to the
benefit of and be enforceable by the parties hereto and their respective

      (e) Remedies. The Company and the Executive each acknowledges that the
Executive Shares are unique and recognizes and affirms that in the event of a
breach of this Agreement by the Company or the Executive, money damages may be
inadequate and the Executive, or the Company, as the case may be, may have no
adequate remedy at law. Accordingly, the Company and the Executive each agrees
that the Executive, or the Company, as the case may be, shall have the right, in
addition to any other rights and remedies existing in its favor at law or in
equity, to enforce its rights and the obligations of the Company or the
Executive (as the case may be) hereunder not only by an action or actions for
damages but also by an action or actions for specific performance, injunctive
