assume, guarantee or otherwise become liable for any new Senior Debt after the
offering Date excepting that the Company may obtain a line of credit from a
commercial bank in the amount up to $2,000,000 which will be superior in right

thereof at the time together with accrued interest. If less than all the Notes

for the selection for redemptions of portions (equal to $1,000 or any integral
multiple thereof) of the principal amount of any Note. Any notice of redemption
shall state: (1) the date of redemption; (2) the redemption price; (3) if less
than all outstanding Notes are to be redeemed, the identification (and, in the
case of partial redemption, the principal amounts) of the particular Notes to be
redeemed; and (4) the place or places where Notes are to be surrendered for
payment of the redemption price. Notice of redemption having been given as

         6.       CONVERSION.

                  (a) VOLUNTARY CONVERSION. Any holder of this Note has the
right, at the Holder's option, prior to payment in full of the principal balance
of this Note, to convert this Note, in accordance with the provisions of Section
6 hereof, in whole or in part, into Common Stock, $.001 par value, of the
Company (the "Common Stock"). The number of shares of Common Stock into which
this Note may be converted ("Conversion Shares") shall be determined by dividing
the aggregate remaining principal balance together with all accrued interest to
the date of conversion by the Conversion Price (as defined below) in effect at
the time of such conversion. The initial Conversion Price shall be equal to two
dollars ($2.00) subject to adjustments as provided in Section 10 hereof.

                  (b) AUTOMATIC CONVERSION. The entire principal amount of this
Note shall be automatically converted into shares of Common Stock at the
Conversion Price at the time in effect immediately prior to (i) any
consolidation or merger of the Company with or into any other corporation or
other entity or person, or any other corporate reorganization in which the
Company shall not be the continuing or surviving entity of such consolidation,
merger or reorganization or any transaction or series of related transactions by
the Company in which in excess of fifty percent (50%) of the Company's voting
power is transferred, or a sale of all or substantially all of the assets of the
Company, in each case if the consideration to be received per share of Common
Stock shall be at

                                      -3-

<PAGE>

least Five Dollars ($5.00) per share or (ii) the consummation of a firmly
underwritten public offering pursuant to a registration statement filed by the
Company under the Securities Act of 1933, as amended (the "Act") generating
gross offering proceeds of at least $5,000,000.

                  (c) COMPLIANCE WITH SECURITIES LAWS. The Holder of this Note,
by acceptance hereof, acknowledges that the shares of Common Stock to be issued
upon conversion thereof are being acquired solely for the Holder's own account
and not as a nominee for any other part, and for investment, and that the Holder
will not offer, sell or otherwise dispose of any shares of Common Stock to be
issued upon conversion thereof except under circumstances that will not result
in a violation of the Act or any state securities laws. Upon conversion of this
Note, the Holder shall, if requested by the Company, confirm in writing, in a
form satisfactory to the Company, that the shares of Common Stock issued upon
conversion are being acquired solely for the Holder's own account and not as a
nominee for any other party, for investment, and not with a view toward
distribution or resale. All shares of Common Stock issued upon conversion
thereof shall be stamped or imprinted with a legend in substantially the
following form (in addition to any legend required by state securities laws):

THE SHARES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AS AMENDED. SUCH SHARES MAY NOT
BE SOLD, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE
OF SUCH REGISTRATION OR UNDER SAID ACT OR OPINION OF COUNSEL SATISFACTORY TO THE
COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED. COPIES OF THE
AGREEMENT RESTRICTING THE TRANSFER OR SALE OF THESE SHARES MAY BE OBTAINED AT NO
COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD HEREOF TO THE SECRETARY OF
THE COMPANY AT THE PRINCIPAL EXECUTIVE OFFICES OF THE COMPANY.

         7.       CONVERSION PROCEDURE.

                  (a) NOTICE OF CONVERSION PURSUANT TO SECTION 6(a). Before the
Holder shall be entitled to convert this Note into shares of Common Stock, it
shall surrender this Note at the office of the Company and shall give at least
ten (10) days' advance written notice by mail, postage prepaid, to the Company
at its principal corporate office, of the election to convert the same, if the
Holder is electing to convert pursuant to Section 6(a), and shall state therein
the name or names in which the certificate or certificates for shares of Common
Stock are to be issued. The Company shall, as soon as practicable thereafter,
issue and deliver at such office to the Holder of this Note a certificate or
certificates for the number of shares of Common Stock to which the Holder of
this Note shall be entitled as aforesaid.

                  (b) NOTICE OF CONVERSION PURSUANT TO SECTION 6(b). If this
Note is automatically converted, written notice shall be delivered to the Holder
of this Note at the address last shown on the records of the Company for the

<PAGE>

principal executive office of the Company is located, notifying the Holder of
the conversion to be effected, specifying the Conversion Price, the principal
amount of the Note to be converted, the amount of accrued interest to be
converted, the date on which such conversion will occur and calling upon such
Holder to surrender to the Company, in the manner at the place designated, the

         8. DELIVERY OF STOCK CERTIFICATES. As promptly as practicable after the
conversion of this Note, the Company at its expense will issue and deliver to
the Holder of this Note a certificate or certificates for the number of full
shares of Common Stock issuable upon such conversion.

         9. MECHANICS AND EFFECT OF CONVERSION. No fractional shares of Common
Stock shall be issued upon conversion of this Note. In lieu of the Company
issuing any fractional shares to the Holder upon the conversion of this Note,
the Company shall pay to the Holder the amount of outstanding principal and
accrued interest that is not so converted, such payment to be in the form as
provided below. Upon the conversion of this Note pursuant to Section 6(a) above,
the Holder shall surrender this Note, duly endorsed, at the principal office of
the Company. At its expense, the Company shall, as soon as practicable
thereafter, issue and deliver to such Holder at such principal office a
certificate or certificates for the number of shares of such Common Stock to
which the Holder shall be entitled upon such conversion (bearing such legends as
are required by the Subscription Agreement and applicable state and federal
securities laws in the opinion of counsel to the Company), together with any
other securities and property to which the Holder is entitled upon such
conversion under the terms of this Note, including a check payable to the Holder
for any cash prior to the close of business on the date of such surrender of
this Note, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock as of such date. Upon
conversion of this Note, the Company shall be forever released from all its
obligations and liabilities under this Note, except ten (10) days after the date
of such conversion, any interest accrued and unpaid or unconverted to and
including the date of such conversion, and no more.

         10.      ADJUSTMENTS TO CONVERSION PRICE.

                  (a) In the event the Company should at any time or from time
to time after the date of issuance hereof fix a record date for the effectuation
of a split or subdivision of the outstanding shares of Common Stock or the
determination of holders of Common Stock entitled to receive a dividend or other
distribution payable in additional shares of Common Stock or other securities or
rights convertible into, or entitling the holder thereof to receive, directly or
indirectly, additional shares of Common Stock (hereinafter referred to as
"Common Stock Equivalents") without payment of any consideration by such holder
for the additional shares of Common Stock Equivalents (including the additional
shares of Common Stock issuable upon conversion or exercise thereof), then, as
of such record date (or the date of such dividend distribution, split or
subdivision if no record date is fixed), the Conversion Price of this Note shall
be appropriately decreased so that the number of shares of Common Stock issuable
upon conversion of this Note shall be increased in proportion to such increase
of outstanding shares.

                                      -5-

<PAGE>

                  (b) If the number of shares of Common Stock outstanding at any
time after the date hereof is decreased by a combination of the outstanding
shares of Common Stock, then, following the record date of such combination, the
Conversion Price for this Note shall be appropriately increased so that the
number of shares of Common Stock issuable on conversion hereof shall be
decreased in proportion to such decrease in outstanding shares.

                  (c) Upon the occurrence of each adjustment of the Conversion
Price pursuant to this Section 6 the Company shall promptly compute such
adjustment in accordance with the terms hereof and prepare and furnish to the
Holder a certificate setting forth the facts upon which such adjustment is
based. In the case of an adjustment pursuant to Section 10(c), the Company shall
furnish to Holder a copy of its audited financial statements for such fiscal
year.

         11.      NOTICES OF RECORD DATE, ETC.  In the event of

                  (a) any taking by the Company of a record of the holders of
any class of securities of the Company for the purpose of determining the
holders thereof who are entitled to receive any dividend (other than a cash
dividend payable out of earned surplus at the same rate as that of the last such
cash dividend theretofore paid) or other distribution, or any right to subscribe
for, purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right;

                  (b) any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company or any
transfer of all or substantially all of the assets of the Company to any other
person or any consolidation or merger involving the Company; or

                  (c) any voluntary or involuntary dissolution, liquidation or
winding-up of the Company, the Company will mail to the holder of this Note at
least fifteen (15) days prior to the earliest date specified therein, a notice
specifying:

                           i.       The date of which any such record is to be
taken for the purpose of such dividend, distribution or right, and the amount
and character of such dividend, distribution or right; and

                           ii.      The approximate date on which any such
reorganization, reclassification, transfer, consolidation, merger, dissolution,
liquidation or winding-up is expected to become effective and the record date
for determining stockholders entitled to vote thereon.

         12. RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The Company shall at
all times reserve and keep available, out of its authorized but unissued shares
of Common Stock solely for the purpose of effecting the conversion of the Notes,
such number of its shares of Common Stock as shall from time to time be
sufficient to effect the conversion of the Notes; and if at any time the number
of authorized but unissued shares of Common Stock (and shares of its Common
Stock for

                                      -6-

<PAGE>

issuance on conversion of such Common Stock) shall not be sufficient to effect
the conversion of the entire outstanding principal amount of this Note, in
addition to such other remedies as shall be available to the Holder of this
Note, the Company will use its best efforts to take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but
unissued shares of Common Stock to such number of shares as shall be sufficient
for such purposes.

         13. ASSIGNMENT. Subject to the restrictions on transfer described in
Section 15 below, the rights and obligations of the Company and the Holder of
this Note shall be binding upon and benefit the successors, assigns, heirs,
administrators and transferees of the parties.

         14. WAIVER AND AMENDMENT. Any provision of this Note may be amended,
waived or modified upon the approval of the Company and the Holders of a
majority of the outstanding principal amount of all then outstanding Notes
issued pursuant to the Subscription Agreement.

         15. TRANSFER OF THIS NOTE OR SECURITIES ISSUABLE ON CONVERSION HEREOF.
With respect to any offer, sale or other disposition of this Note or securities
into which such Note may be converted, the Holder will give written notice to
the Company prior thereto, describing briefly the manner thereof, together with
a written opinion of such Holder's counsel reasonably satisfactory to Company
and its counsel, to the effect that such offer, sale or other disposition may be
effected without registration or qualification (under any federal or state law
then in effect). Promptly upon receiving such written notice and opinion, the
Company, as promptly as practicable, shall notify such Holder that such Holder
may sell or otherwise dispose of this Note or such securities, all in accordance
with the terms of the notice delivered to the Company. If a determination has
been made pursuant to this Section 15 that the opinion of counsel for the Holder
is not reasonably satisfactory to the Company, the Company shall so notify the
Holder promptly after such determination has been made. The Company may issue
stop transfer instructions to its transfer agent in connection with such
restrictions.

         16. NOTICES. Any notice, request or other communication required or
permitted hereunder shall be in writing and shall be deemed to have been duly
given if personally delivered or if telegraphed or mailed by registered or
certified mail, or overnight air courier, postage prepaid, at the respective

be deemed to have been given when personally delivered or when deposited in the
mail or with an air courier or telegraphed in the manner set forth above and

construed as conferring upon the Holder or any other person the right to vote or
to consent or to receive notice as a shareholder in respect of meetings of
shareholders for the election of directors of the Company or any other matters
or any rights whatsoever as a shareholder of the Company; and no dividends or
interest shall be payable or accrued in respect of this Note or the interest
represented hereby or the Conversion Shares obtainable hereunder until, and only
to the extent that, this Note shall have been converted.

                               PARTSBASE.COM, INC.

                       AMENDED RESTRICTED STOCK BONUS PLAN

1.   PURPOSE

     This plan's purpose is to keep Recipients and consultants of experience and

     For purposes of this Plan, the following terms will have the definitions
     set forth below:

     1.   "AGREEMENT." An agreement between the Company and the Recipient as to
          vesting and other conditions restrictions as to the bonus stock award

          the ordinary voting power for the election of directors.

     4.   "BOARD." The Company's Board of Directors.

     5.   "DATE OF ISSUANCE." This term shall have the meaning supplied by
          Section 6(c), below.

     6.   "PLAN." The PartsBase.com, Inc. Amended Restricted Stock Bonus Plan.

     7.   "BONUS SHARE." The shares of common stock of the Company reserved

<PAGE>

     8.   "RECIPIENT." A Recipient or consultant of the Company or a Subsidiary
          to whom shares are allocated under this Plan, or such individual's
          designated beneficiary, surviving spouse, estate, or legal

          person with the Recipient.

     9.   "RESTRICTED PERIOD." This phrase shall have the meaning supplied by

3.   BONUS SHARE RESERVE

     1.   BONUS SHARE RESERVE. The Company will establish a Bonus Share reserve
          to which will be credited 1,000,000 shares of the common stock of the
          Company, no par value. Should the shares of the Company's common
          stock, due to a stock split or stock dividend or combination of shares
          or any other change, or exchange for other securities, by
          reclassification, reorganization, merger, consolidation,

     2.   ADJUSTMENTS TO RESERVE. Upon the allocation of shares hereunder, the
          reserve will be reduced by the number of shares so allocated and, upon

          shall be fully paid and non-assessable shares and free from preemptive
          rights.

4.   ELIGIBILITY AND MAKING OF ALLOCATIONS

     1.   ELIGIBLE PARTICIPANTS. Any salaried executive Recipient or consultant
          of the Company or any Subsidiary (including officers and directors,
          except for

<PAGE>

          persons serving as directors only) shall be eligible to receive an
          allocation of Bonus Shares pursuant to the Plan.

     2.   SELECTION BY BOARD. The Board will, in its discretion, allocate to the
          Recipients or consultants the Board selects a number of Bonus Shares.
          The date of such action by the Board shall be the "date of
          allocation," as that term is used in this Plan.

     3.   PARTICIPATION IN OTHER STOCK OPTION PLANS. A person who has received
          options to purchase stock under any stock option plan of the Company
          or a Subsidiary may exercise the same in accordance with their terms,
          and will not by reason thereof be ineligible to receive Bonus Shares
          under this Plan. A person who has received Bonus Shares shall be
          eligible to, and may, be granted any option or other rights to
          purchase Common Stock pursuant to any stock option plan or stock
          purchase plan of the Company presently in effect of hereafter adopted.

     4.   LIMIT ON NUMBER OF ALLOCABLE SHARES. The total number of Bonus Shares
          which may be allocated pursuant to this Plan will not exceed the
          amount available therefor in the Bonus Share reserve.

5.   FORM OF ALLOCATIONS

     1.   NUMBER SPECIFIED. Each allocation shall specify the number of Bonus
          Shares subject thereto, subject to the provisions of SECTION 4.

     2.   NOTICE. When an allocation is made, the Board shall advise the
          Recipient and the Company thereof by delivery of written notice in the
          form of Exhibit A hereto annexed.

6.   AGREEMENT REQUIRED OF RECIPIENTS

     1.   ACCEPTANCE OF ALLOCATION. Within 15 days from the date of allocation,
          the Recipient shall, if he desires to accept the allocation, execute
          the Agreement applicable to the award.

     2.   INVESTMENT PURPOSE. The Company may require that, in acquiring any
          Bonus Shares, the Recipient agree with, and represent to, the Company
          that the Recipient is acquiring such Bonus Shares for the purpose of
          investment and with no present intent to transfer, sell, or otherwise
          dispose of such shares except for such distribution by a legal
          representative as shall be required by will or the laws of any
          jurisdiction in winding up the estate of any Recipient.

<PAGE>

          Such shares shall be transferable thereafter only if the proposed
          transfer is permitted under the Plan and if, in the opinion of counsel
          (who shall be satisfactory to the Company), such transfer at such time
          complies with applicable securities laws.

     3.   WRITTEN AGREEMENT/DATE OF ISSUANCE. On delivery of the Agreement to
          the Company, the Company will promptly acknowledge its receipt
          thereof. The date of such delivery and receipt shall be deemed the
          "Date of Issuance," as that phrase is used in this Plan, of the Bonus
          Shares to which the shares relate. The failure to make such payment
          and delivery within 15 days from the date of allocation shall
          terminate the allocation of such shares to the Recipient.

7.   RESTRICTIONS

     1.   TRANSFER/ISSUANCE. Bonus Shares after the execution of the Agreement
          required by SECTION 6, will be promptly issued or transferred and a
          certificate or certificates for such shares shall be issued in the
          Recipient's name. The Recipient shall thereupon be a shareholder of
          all the shares represented by the certificate or certificates. As
          such, the Recipient will have all the rights of a shareholder with
          respect to such shares, including the right to vote them and to
          receive all dividends and other distributions (subject to SECTION
          7(b)) paid with respect to them, provided, however, that the shares
          shall be subject to the restrictions in SECTION 7(d) and the
          Agreement. Stock certificates representing Bonus Shares will be
          imprinted with a legend stating that the shares represented thereby
          may not be sold, exchanged, transferred, pledged, hypothecated, or
          otherwise disposed of except in accordance with this Plan's terms and
          the terms of the Agreement between the Company and the Recipient.

     2.   STOCK SPLITS, DIVIDENDS, ETC. If, due to a stock split, stock
          dividend, combination of shares, or any other change or exchange for
          other securities by reclassification, reorganization, merger,
          consolidation, recapitalization or otherwise, the Recipient, as the
          owner of Bonus Shares subject to restrictions hereunder, shall be
          entitled to new, additional, or different shares of stock or
          securities, the certificate or certificates for, or other evidences
          of, such new, additional, or different shares or securities also shall
          be imprinted with a legend as provided in SECTION 7(a). When the
          event(s) described in the preceding sentence occur, all Plan
          provisions relating to restrictions and lapse of restrictions will
          apply to such new, additional, or different shares or securities to
          the extent applicable to the shares with respect to which they were
          distributed.

<PAGE>

     3.   RESTRICTED PERIOD. Subject to SECTION 10, the restrictions contained
          in SECTION 7(d) hereof shall lapse as provided in the Agreement
          between the Company and the Recipient.

     4.   RESTRICTIONS ON BONUS SHARES. The restrictions to which restricted
          Bonus Shares shall be subjected are as provided in the Agreement
          between the Company and the Recipient.

          During the Restricted Period applicable to such shares and except as
          otherwise specifically provided in the Plan or the Agreement, none of
          such shares shall be sold, exchanged, transferred, pledged,
          hypothecated, or otherwise disposed of.

8.   FINALITY OF DETERMINATION

     The Committee will administer this Plan and construe its provisions. Any
     determination by the Committee carrying out, administering, or construing
     this Plan will be final and binding for all purposes and upon all
     interested persons and their heirs, successors, and personal
     representatives.

9. LIMITATIONS

     1.   NO RIGHT TO ALLOCATION. No person will at any time have any right to
          receive an allocation of Bonus Shares hereunder and no person will
          have authority to enter into an agreement for the making of an
          allocation or to make any representation or warranty with respect
          thereto.

     2.   RIGHTS OF RECIPIENTS. Recipients of allocations will have no rights in
          respect thereof other than those set forth in the Plan. Such rights
          may not be assigned or transferred except by will or by the laws of
          descent and distribution and if permitted under SECTION 6(b). If any
          attempt is made to sell, exchange, transfer, pledge, hypothecate, or
          otherwise dispose of any Bonus Shares held by the Recipient under
          restrictions which have not yet lapsed, the shares that are the
          subject of such attempted disposition will be deemed offered to the
          Company for repurchase and the Company may, at its option, repurchase
          the shares at the lower of the sale price to the third part or fair
          market value as determined by an independent appraiser mutually
          acceptable to the parties. If the Company and Recipient cannot agree
          on a third party appraiser, each party shall appoint an appraiser and
          the two appraisers shall appoint a third appraiser whose appraisal
          shall be binding on all parties. Before issuance of Bonus Shares, no
          such shares will be

<PAGE>

          earmarked for the Recipients' accounts nor will such Recipients have
          any rights as stockholders with respect to such shares.

     3.   NO RIGHT TO CONTINUED EMPLOYMENT. Neither the Company's action in
          establishing the Plan, nor any action taken by it or by the Board or
          the Committee under the Plan, nor any provision of the Plan, will be
          construed as giving to any person the right to be retained in the
          employ of the Company or any Subsidiary.

     4.   LIMITATION ON ACTIONS. Every right of action by or on behalf of the
          Company or by any shareholder against any past, present, or future
          member of the Board, the Committee, or any officer or Recipient of the
          Company arising out of or in connection with this Plan shall,
          regardless of the place where the action may be brought and regardless
          of the place of residence of any such director, committee member,
          officer or Recipient, cease and be barred by the expiration of three
          years from the later of:

          (i)  the date of the act or omission in respect of which such right of
               action arises or

          (ii) the first date upon which there has been made generally available
               to shareholders an annual report of the Company and a proxy
               statement for the annual meeting of shareholders following the
               issuance of such annual report, which annual report and proxy
               statement alone or together set forth, for the related period,
               the amount of the allocations.

          In addition, any and all right of action by any Recipient (past,
          present or future) against the Company or any member of the Committee
          arising out of or in connection with this Plan will, regardless of the
          place where action may be brought and regardless of the place of
          residence of any Committee member, cease and be barred by the
          expiration of three years from the date of the act or omission in
          respect of which such right of action arises.

10.  AMENDMENT, SUSPENSION OR TERMINATION OF PLAN

     The Board may amend, suspend or terminate the Plan in whole or in part at
     any time; provided that such amendment will not affect adversely rights or
     obligations with respect to allocations previously made; and provided
     further, that no modification of the Plan by the Board without approval of
     the stockholders will (i) increase the maximum number of Bonus Shares
     reserved pursuant to SECTION 3; or (ii) change the provisions of SECTION 4
     with respect to the total number of Bonus Shares that may be allocated
     under the Plan.

To:  1.   _________, Recipient, and

thousand (6,000) Bonus Shares under and pursuant to the Amended Restricted Stock
Bonus Plan.

                                                           For the Board

Date:  August 3, 1999

<PAGE>

                                   EXHIBIT "B"

             PARTSBASE.COM, INC. AMENDED RESTRICTED STOCK BONUS PLAN

To:  Treasurer, PartsBase.com, Inc.

     I represent and agree that I am acquiring these Bonus Shares for investment
and that I have no present intention to transfer, sell or otherwise dispose of
such shares, except as permitted pursuant to the Plan and in compliance with
applicable securities laws. I agree further that I am acquiring these shares in
accordance with, and subject to, the terms, provisions and conditions of said
Plan, which I have read and to which I hereby expressly assent. These agreements
will bind and inure to the benefit of my heirs, legal representatives,
successors and assigns.

     I agree to the following restriction as to the Bonus Shares: I shall not
sell, exchange, transfer, pledge, hypothecate or dispose of shares during the
Restricted Period. In the event of termination of my employment for any reason,
including death or disability, all shares subject to restrictions shall be
returned to or canceled by the Company and shall be deemed to have been
forfeited by the Recipient, unless and then only to the extent that the Board of
Directors shall, in its sole discretion, elect in writing to waive said return
and forfeiture.

     The restrictions will lapse as to such shares in accordance with the
following times and number of shares. This period of time during which the
restrictions apply to a specific share of stock is the Restricted Period as to
that share of stock.

     (i)  Restrictions shall lapse with respect to one-twenty fourth (1/24) of
          the restricted Bonus Shares awarded pursuant to a Restricted Stock
          Award, on the first day of each month following the calendar month of
          the Date of Issuance, but as to employees, only if on the date the
          restrictions are to lapse the Recipient has been an employee of the
          Company continuously from the Date of Issuance of the Restricted Stock
          Award to such date of lapse. Temporary leaves of absence which are
          approved by the Company shall not be considered a break in that
          employee's continuous employment with the Company. The purpose of the
          restriction is to provide an incentive to each employee who is a
          Recipient to remain with the Company or one of its Subsidiaries and to
          perform assigned tasks and responsibilities in a manner consistent
          with the best interest of the Company and its stockholders. If
          calculation of the lapse amount for any month would result

<PAGE>

          in a fractional share interest, the number of shares shall be rounded
          down to the next lowest number of full shares for each of the lapse
          dates, with the balance on the last lapse date.

     (ii) The Compensation Committee may at any time in its sole discretion
          accelerate or waive all or any portion of the restrictions remaining
          in respect to the Bonus Shares. This right may be exercised for any or
          all of the Recipients.

    (iii) Notwithstanding any other provisions of this Agreement, the Recipient
          agrees to execute an agreement not to sell his shares even though
          otherwise vested for a period of up to twenty-four months if an
          underwriter of an initial public offering of the Company's stock
          requests such a restriction. This provision shall lapse as to the
          Restricted Stock Award to a Recipient two years after the restrictions
          as to all of the shares of a Restricted Stock Award have lapsed.

My address of record is:

My Social Security Number is:

                                                    ___________________________

acknowledged.
