          WHEREAS, on April 12, 2001 (the "Date of Grant"), the Board of
Directors (the "Board") of the Company awarded the Grantee 200,000 shares of the
Company's Common Stock, par value $0.01 ("Common Stock"), pursuant to, and
subject to the terms and provisions of the Plan.

          NOW, THEREFORE, in consideration of the Grantee's services to the
Company and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Parties hereto agree as

     1.   Grant of Restricted Stock and Escrow of Restricted Stock.
          --------------------------------------------------------

          a.   Grant of Restricted Stock. The Grantee is entitled to 200,000
               -------------------------
shares of Common Stock pursuant to the terms and conditions of this Agreement
(the "Restricted Stock").

          b.   Escrow of Restricted Stock.  To insure the availability for
               --------------------------
delivery of the Grantee's Restricted Stock, the Grantee hereby appoints the
Secretary of the Company, or any other person designated by the Company as
escrow agent, as its attorney-in-fact to assign and transfer unto the Company
such Restricted Stock, if any, forfeited by the Grantee pursuant to Section 4
below and shall, upon execution of this Agreement, deliver and deposit with the
Secretary of the Company, or such other person designated by the Company, the
share certificates representing the Restricted Stock, together with the stock
assignment duly endorsed in blank, attached hereto as Exhibit A.  The Restricted
Stock and stock assignment shall be held by the Secretary in escrow until the
Restricted Period (as defined below) has lapsed with respect to the shares of
Restricted Stock, or until such time as this Agreement no longer is in effect.

     2.   Restrictions and Restricted Period.
          ----------------------------------

          a.   Restrictions. Shares of Restricted Stock granted hereunder may
               ------------
not be sold, assigned, transferred, pledged, hypothecated or otherwise disposed
of and shall be subject to a risk of forfeiture as described in Section 4 below
until the lapse of the Restricted Period (as defined below).


<PAGE>

          b.   Restricted Period.  Unless the Restricted Period is previously
               -----------------
terminated pursuant to Section 4 of this Agreement, the restrictions set forth
above shall lapse and the shares of Restricted Stock shall become fully and
freely transferable (provided, that such transfer is otherwise in accordance
with federal and state securities laws) and non-forfeitable as to 7/48 of the
shares of Restricted Stock (rounded down to the nearest whole share) on May 12,
2001 and as to an additional 1/48 (rounded down to the nearest whole share) on
the 12th day of each month, beginning June 12, 2001 (the "Restricted Period").
Notwithstanding anything to the contrary, the release of the shares of
Restricted Stock hereunder shall be conditioned upon Grantee making adequate
provision for federal, state or other tax withholding obligations, if any, which
arise upon the release of the shares from the Restricted Period (unless a
Section 83(b) election has been filed), whether by withholding, direct payment
to the Company, or otherwise.

     3.   Rights of a Stockholder.  From and after the Date of Grant and for so
          -----------------------
long as the Restricted Stock is held by or for the benefit of the Grantee, the
Grantee shall have all the rights of a stockholder of the Company with respect
to the Restricted Stock, including, but not limited to, the right to receive
dividends and the right to vote such shares.

     4.   Cessation of Employment.
          -----------------------

          a.   Termination of Employment Unrelated to a Change in Control.  In
               ----------------------------------------------------------
the event of the Grantee's termination of employment which termination does not
constitute a Qualifying Termination (as such term is defined in Grantee's
employment agreement with the Company dated as of September 18, 2000 (the
"Employment Agreement"), the shares of Restricted Stock and any and all accrued
but unpaid dividends that are at that time subject to restrictions set forth
herein, shall be forfeited to the Company without payment of any consideration
by the Company, and neither the Grantee nor any of his successors, heirs,
assigns, or personal representatives shall thereafter have any further rights or
interests in such shares of Restricted Stock or certificates.  In the event of a
Qualifying Termination of Grantee's employment with the Company, the Restricted
Period shall lapse with respect to 50% of the shares of Restricted Stock that
are at that time subject to restrictions set forth herein, and the remaining 50%
of the shares of Restricted Stock that are at that time subject to restrictions
set forth herein shall be forfeited to the Company without payment of any
consideration by the Company, and neither the Grantee nor any of his successors,
heirs, assigns, or personal representatives shall thereafter have any further
rights or interests in such shares of Restricted Stock or certificates.  In the
event Grantee becomes a Consultant or non-Employee Director, such change in
status shall be deemed a termination of employment or service with the Company
at the time of such change in status whereupon, the provisions of this Section 4
shall apply.

          b.    Change of Control; Termination of Employment in Connection with
                ---------------------------------------------------------------
a Change in Control. In the event Grantee is employed by the Company and there
-------------------
is a Change in Control (as such term is defined in the Employment Agreement),
the Restricted Period shall lapse with respect to 50% of the shares of
Restricted Stock that is

                                       2
<PAGE>

at that time subject to restrictions set forth herein, and the remaining shares
of Restricted Stock that are subject to the Restricted Period shall continue to
be released from the Restricted Period in accordance with Section 2(b). In the
event a Qualifying Termination occurs in connection with a Change in Control or
within eighteen months following a Change in Control, the Restricted Period
shall lapse with respect to all of the Restricted Stock that are at that time
subject to restrictions set forth herein. In the event Grantee becomes a
Consultant or non-Employee Director, such change in status shall be deemed a
termination of employment or service with the Company at the time of such change
in status whereupon, the provisions of this Section 4 shall apply.

     5.   Certificates.  Restricted Stock granted herein may be evidence in
          ------------
such manner as the Board shall determine.  If certificates representing
Restricted Stock are registered in the name of the Grantee, then the Company
shall retain physical possession of the certificate.

     6.   Legends. All certificates representing any of the shares of Restricted
          -------
Stock subject to the provisions of this Agreement shall have endorsed thereon
the following legend:

          RESTRICTIONS UPON TRANSFER AS SET FORTH IN AN AGREEMENT BETWEEN THE
          COMPANY AND THE HOLDER OF THE SHARES, A COPY OF WHICH IS ON FILE AT
          THE PRINCIPAL OFFICE OF THE COMPANY."

     7.   Tax Consequences. Set forth below is a brief summary as of the Date of
          ----------------
grant of certain United States federal tax consequences of the award of the
Restricted Stock. THIS SUMMARY DOES NOT ADDRESS SPECIFIC STATE, LOCAL OR FOREIGN
TAX CONSEQUENCES THAT MAY BE APPLICABLE TO GRANTEE. GRANTEE UNDERSTANDS THAT
THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE

may be filed by the Grantee with the Internal Revenue Service, within 30 days of
the Date of Grant, electing pursuant to Section 83(b) of the Internal Revenue
