Mr. Neil G. Cohen
3 Whittier Way
Livingston, NJ 07039

Dear Neil:

I am pleased to set forth the terms of your employment as Executive Vice
President and General Counsel of Optimark, Inc. (the "Company"). The terms of
your employment agreement dated June 9, 1999, as amended, shall remain in full
force and effect. The terms set forth in this letter will be deemed effective as
of May 18, 2001.

You will serve as Executive Vice President and General Counsel of the Company
and will report to me. You will be responsible for such duties as are normally
associated with such position or as otherwise determined by the Board of
Directors, except that the Company agrees that you will not at any time be given
a lesser title than the one stated above.

As compensation for the services you provide the Company, you will be paid a
base salary of two hundred thousand dollars ($200,000.00) per annum, which will
be payable in accordance with the Company's regular payroll practices. Also, you
will (i) be eligible to participate in all employee benefits provided by the
Company to its employees, including the Company's bonus program; (ii) receive
three weeks vacation per year, which is earned pro-rata over the year; and (iii)
receive 5 paid-time-off days (personal/sick) per year.

You will be eligible to participate in the "OptiMark Holdings, Inc. 1999 Stock
Plan" (the "Stock Plan"), as amended. Subject to the appropriate approvals,
including approval of the Board of Directors, and amendment of the Stock Plan,

if necessary, to increase the number of shares allocated to the Stock Plan, you
will be granted an Incentive Stock Option to purchase an aggregate number of
shares equal to one-half of a percent (0.5%) of the outstanding shares of par
value $0.01 common stock of the Company's parent, OptiMark Holdings, Inc., (the
"Stock"), calculated on a fully diluted basis as of May 18, 2001. The exercise
price to purchase the Stock will be the fair market value of the Stock as of May
18, 2001.

In the event that the Company's parent, OptiMark Holdings, Inc., undergoes a
change in capitalization and creates a new stock plan for a new class of stock,
you will participate in the same manner as other members of the senior
management team, except that the initial percentages of common stock to which
you and they are entitled will differ.

In the event that the Company terminates your employment for a reason other than
for "cause", as defined in your employee agreement, you will receive severance
pay in the amount of four (4) months base salary. In addition, the Company
agrees that it will continue making employment level contributions for all
employee benefit plans provided to you by the Company during your employment,
for a period of four (4) months following the termination of your employment.

The relationship between you and the Company will be for an unspecified term and
will be considered at will. No employment contract is created by the existence
of any policy, rule or procedure in the Company's handbook, any document of the
Company, or any verbal statements made to you by representatives of the Company.
Consequently, the employment relationship between you and the Company can be
terminated at will, either by you or the Company, with or without cause or
advance notice.

Your employment with the Company is considered exclusive to the Company and, as
a condition of your employment, we do not expect, nor will we allow, you to
perform services for compensation for any third party.

The employment terms in this letter and the employee agreement supersede any
other agreements or promises made to you by anyone, whether oral or written, and
comprise the final, complete and exclusive agreement between you and the
Company.

                                             Very truly yours,

                                             Optimark, Inc.

Neil G. Cohen

Date: June 22, 2001Exhibit 10.33
                              EMPLOYEE AGREEMENT
                                 (Version II)

         In consideration of my employment or continued employment by
OptiMark, Inc.(the "Company"), I agree to the terms and conditions of
employment set forth below.

         1. CONFLICT OF INTEREST. At the time of signing this Agreement, I
have no obligation to any prior employer or other person or organization which
would interfere with my performance of my work for the Company or which would
result in any conflict of interest for the Company or its customers or
clients, except as I have noted in attachment A hereto. Further, I have made
no commitment and have no restriction on my service which is a result of any
past or present consulting agreement, directorship, ownership interest or
other affiliation or connection with any other organization, except as I have
noted in attachment A hereto, and will not enter into such commitments or be
encumbered by such restrictions without receiving prior written approval from
the Company. During the period of my employment by the Company, I will not
engage in any other employment or other activity which may be inconsistent
with my obligations to the Company and its investors, business partners,
customers and clients.

         2. CONFIDENTIAL INFORMATION. In the course of my employment by the
Company, I may become aware of confidential information including, without
limitation, computer system and software designs, plans for new product and
service offerings, dealings with regulators, customer lists, market research,
strategic plans or other similar information that relates to the business of
the Company, its investors, business partners, customers or clients. I will
not use or disclose any such confidential information of the Company or its
investors, business partners customers or clients except in fulfillment of my
obligations to the Company or unless ordered to do so by a court of competent
jurisdiction (in which latter case I will promptly inform the Company of such
order). I will comply with the Company's policies and procedures for the
protection of confidential information. Further, my obligation not to disclose
or use such confidential information will continue for a period of two years
after the termination of my employment for whatever reason.

         3. INTELLECTUAL PROPERTY. I fully and promptly will disclose and
describe to the Company, and hereby agree to assign to the Company, all of my
full right, title, and interest in all intellectual property, including,
without limitation, all inventions, discoveries, concepts, ideas, systems,
methods, processes, works, computer programs and computer software (whether or
not patentable or copyrightable or constituting trade secrets), which I make,
conceive, reduce to practice, or create as an employee of or in connection
with my employment by the Company. I also will disclose and assign to the
Company all of my interest, if any, in any such intellectual property
conceived of or created by other employees or by clients of the Company during
the period of my employment by the Company. I understand that I will have no
rights to any royalties or other compensation for the use of any intellectual
property covered by this Agreement, unless expressly agreed to in writing by
the Company. This paragraph 3, however, shall not apply to intellectual
property that meets all of the following requirements: (i) it does not relate
to the actual business or research and development of the Company, or to
business or research and development under consideration by the Company that
is known to me, (ii) it is made or conceived of by me during times not working
as an employee of the Company (whether or not during normal business hours or
on Company premises), and (iii) it is not

<PAGE>

derived from, and is made without the use of, any intellectual property or
confidential information of the Company. I own the discoveries, improvements
or inventions identified in attachment A hereto, which discoveries,
improvements or inventions are expressly reserved and excepted from the
provisions of this Agreement.

         4. PATENTS. I will cooperate with the Company in doing whatever is
appropriate, including executing assignments, to apply for, obtain and enforce
patent rights (U.S. and/or foreign) for the Company or its clients on any
invention which is made by me (either alone or jointly with others) during my
employment, provided that (a) all expenses required to apply for, obtain and
enforce any patent rights will be paid by the Company, and (b) if I am
required to spend a substantial amount of time to carry out my obligations
under this paragraph 4, I will be entitled to reasonable compensation from the
Company for that time. I understand that the Company will have no obligation
to me to apply for or obtain any such patent rights.

         5. WRITINGS. Any written materials or software that I prepare, in
whole or in part, during the course of my employment with the Company, will be
the property of the Company. I hereby assign to the Company all of my full
right, title and interest in any such written materials or software. I also
will do whatever is appropriate to obtain copyright protection of any such
written materials or software relating to my work for the Company or its
clients, should the Company so request.

         6. FINANCIAL OBLIGATIONS. If I am provided with travel advances or
other advances of expenses in connection with my employment with the Company,
I will make a prompt settlement of all such advances after completion of the
travel or other employment-related activities. If I owe any money to the
Company at the time of termination of my employment, such amount owed to the
Company may be deducted from any money otherwise owed to me by the Company.

         7. REASONABLE NOTICE OF TERMINATION I understand that, unless
expressly provided otherwise in any other written agreement signed by me and
an authorized officer of the Company, my employment with the Company is "at
will", and my employment may be terminated by the Company at any time, with or
without cause or prior notice. I understand that termination of my employment
will be deemed to be with cause only if I am terminated for gross negligence
(but not ordinary negligence), intentional misconduct, breach of this or any
other written employment agreement with the Company, or repeated failure to
comply with reasonable directives of the Company's Chief Executive Officer or
Board of Directors, all as determined by a unanimous vote of said Board, or if
I am convicted of or plead guilty or novo contender to a felony or crime of
moral turpitude.

         8. COMPANY PROPERTY. Upon the termination of my employment with the
Company, or during my employment if so requested by the Company, I will deliver
to an authorized representative of the Company (a) all credit cards,
identification cards, badges, keys, and other items which have been provided to
me by the Company, (b) all tools, equipment, and software provided to me by the
Company, and (c) all written materials, records, tapes, disks and other media
which relate to the business of the Company. I will not retain any copies or
duplicates of the items described above, except that I may retain copies of my
own records relating to my compensation from the Company, a copy of this
Agreement, and my personal copies of any papers which have been written by me
and have been published without restriction.

<PAGE>

        9. SOLICITING EMPLOYEES AND CLIENTS. I agree that for a period of 12
months following the termination of my employment with the Company for any
reason, I will not, and will not assist any one else to, directly or
indirectly solicit or induce any of the Company's employees to terminate their
employment with the Company or divert, interfere with or take away from the
Company any person, company or entity which, within the six month period
immediately preceding my termination of employment, was an investor, customer,
client, supplier, business partner, prime contractor, subcontractor or
independent contractor of the Company.

        10. ACKNOWLEDGMENT. I acknowledge that the Company shall not have an
adequate remedy at law in the event I breach this Agreement and that the
Company will suffer irreparable damage and injury in such event. I agree that
the Company, in addition to any other available rights and remedies, shall be
entitled to a preliminary and permanent injunction, without having to post a
bond, restricting me from committing or continuing any violation of this
Agreement.

        11. ENFORCEABILITY. If any provision of this Agreement shall, to any
extent, be found to be invalid or unenforceable, the remainder of this
Agreement shall not be affected thereby, and any such invalid or unenforceable
provision shall be reformed so as to be valid and enforceable to the full
extent permitted by law.

        12. OBLIGATIONS TO THE COMPANY. I understand that I may have
obligations to the Company that are not expressly set forth in this Agreement,
including obligations to perform the duties of my employment with loyalty,
honesty and integrity and in good faith. I understand that I will be required
to comply with all rules, regulations and policies of the Company.

        13. CONTINUING OBLIGATIONS. My obligations under this Agreement will
continue in effect after termination of my employment with the Company. The
provisions of this Agreement will be binding upon my executors,
administrators, or other legal representatives in the event of my death or
disability.

        14. GOVERNING LAW. This Agreement (except for paragraph 7) shall
continue in effect after my employment with the Company terminates, and shall
be governed by and construed in accordance with the laws of the State of New
Jersey.

         15. NO ORAL AGREEMENTS. I understand that (a) this Agreement and any
other written employment agreement include every agreement between the Company
and me with respect to my employment, (b) any and all prior oral agreements
between me and the Company with respect to my employment are terminated and
superseded by this Agreement, (c) no oral agreements between me and the
Company with respect to my employment are or will be enforceable against me or
the Company, and (d) I will not rely on any oral promises from the Company
with respect to my employment, on the understanding that any such promises
must be included in a writing, signed by an officer of the Company, in order
to be enforceable.

                                      3

        16. RECOMMENDATION OF LEGAL ADVICE. I acknowledge the Company's
encouragement for me to have obtained independent legal advice with respect to
this Agreement. I either have obtained or affirmatively waive such advice.
