amended, to which Indenture and all indentures supplemental thereto reference is
hereby made for a statement of the respective rights thereunder of the Company,
the Trustee and the Holders of the Securities, and the terms upon which the
Securities are, and are to be, authenticated and delivered. All terms used in

            After the completion of the issuance for which this Note is a part,

Securities with the same terms (including maturity and interest payment terms)
as this Note. After such additional Securities are issued, they will be fungible

percentages in aggregate principal amount of the Securities of each series at

to waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Note shall be conclusive and binding
upon such Holder and upon all future Holders of this Note and of any Note issued

                  AMENDMENT NO. 3, dated as of August 8, 2002 (the "Amendment")
to the EMPLOYMENT AGREEMENT dated as of August 16, 2001 (as previously amended,
the "Agreement"), between OPTIMARK HOLDINGS, INC., a Delaware corporation (the
"Company"), and ROBERT J. WARSHAW, an individual (the "Executive"). Capitalized
terms used herein without definition shall have the meanings ascribed to them in
the Agreement. All references below to "Sections" are to the corresponding
Sections of the Agreement.

         Whereas the Executive  has been serving as the interim Chief  Executive
Officer of The Ashton Technology  Group,  Inc.  ("Ashton") at the request of the
Company; and

         Whereas, the Company and the Executive desire to amend the Agreement in
accordance with the terms hereof to reflect their understanding concerning the
Executive's service at Ashton.

         Accordingly, in consideration of the premises and mutual covenants
contained herein and for other good and valuable consideration, the receipt and
adequacy of which are mutually acknowledged, the Company and the Executive agree
to amend the Agreement as follows:

                  SECTION 1.01. Amendment to Section 2. Section 2 of the
Agreement is hereby amended by adding the following sentences at the end
thereof:

                  "The Company and the Executive agree that the Term of
         Employment is hereby extended for an additional one-year period ending
         on August 13, 2003. The Executive's Base Salary shall remain at
         $250,000, and the annual incentive award described in Section 5(a)
         shall continue, during such period."

                  SECTION 1.02. Amendment to Section 3. The following new

Agreement:

                  "(c) The Executive shall continue to serve as interim Chief
         Executive Officer of Ashton until December 31, 2002, or if earlier,
         until Ashton employs a permanent Chief Executive Officer. The Executive
         shall also continue to serve as a member of the board of directors of
         Ashton and such other companies as the Company and the Executive
         mutually agree upon. The Executive may be compensated for his duties as
         a member of the board of directors of Ashton (after he ceases to serve
         as Chief Executive Officer) and of any other companies at which he is
         not employed.

                  (d) A portion of the Executive's compensation, including,
         without limitation, the Base Salary and any incentive awards, may be
         paid by Ashton. The amount payable by the Company as Base Salary and
         annual incentive awards hereunder shall be reduced by the amount of any
         cash payments received by the Executive from Ashton on or before
         December 31, 2002;

                                                                               2

                  provided, however, that the Company shall continue to be
         liable for all amounts due under this Agreement to the extent they are
         not so paid by Ashton. In no event shall the total compensation paid to
         the Executive by the Company and Ashton be less than the amounts due to
         the Executive under this Agreement."

                  SECTION 1.03. Amendment to Section 5. The following paragraphs
(c) and (d) are hereby added to the end of Section 5 of the Agreement:

                  "(c) The Company shall pay the Executive a cash bonus of
         $45,000 promptly following the execution of this Agreement.

                  (d) The Company shall pay the Executive a cash bonus of
         $80,000 upon the employment of a full time Chief Executive Officer by

                  terminated within six months after the date the Executive
                  receives the bonus described in Section 5(d), he shall instead

                  delivered notice not to renew this Agreement in accordance
                  with Section 2 or because the Executive has delivered notice
                  not to renew this Agreement under the circumstances set forth
                  in the proviso at the end of Section 4, then the Executive

                  consideration, but in no event less than 90 days from the
                  Termination Date; or (iii) the maximum stated term of the
                  option; and

                           (iii) a severance payment equal to the sum of one
                  year's Base Salary, which is payable in installments in
