        Part A. Employment.

             1. Duties. Subject to the terms and conditions of this Agreement,
the Company shall employ the Employee and the Employee shall render services to
the Corporations in the capacities and with the titles of Senior Vice President,
Chief Financial and Administrative Officer, Secretary and General Counsel of the
Company and each of its Subsidiaries. Employee shall report to the Chairman of
the Board of the Company. Subject always to the direction of the Chairman of the

             2. Full-Time Employment. Throughout the period of his employment
hereunder, the Employee shall devote his full and entire professional and
business time, attention, knowledge and skills to faithfully, diligently and to
the best of his abilities perform his duties hereunder. It is expected that the
Employee will render his services primarily from the Company's New York, New

reasonably required in connection with the performance of his duties hereunder.

             3. Ability to Perform. The Employee hereby represents and warrants
to the Company that he is under no legal disability and has entered into no
agreements which in any way limit or render the Employee incapable of performing
his obligations under this Agreement

                                       2
<PAGE>   3
or his fiduciary duties as the Senior Vice President, Chief Financial and
Administrative Officer, Secretary and General Counsel of the Company. The
Employee further covenants that he will not impair his ability to carry out his
obligations under this Agreement or his fiduciary duties as the Senior Vice
President, Chief Financial and Administrative Officer, Secretary and General
Counsel of the Company by entering into any agreement or in any way assisting
others, directly or indirectly, to enter into any agreement which will violate
the confidentiality and non-competition provisions of Part D of this Agreement.

        Part B. Term of Employment: Termination of Agreement.

             1. Term. Subject to prior termination in accordance with the
provisions hereof, the term of this Agreement shall commence on May 1, 1997 and
shall continue through and including April 30, 1999 (the "Term").
Notwithstanding the foregoing, the Board of Directors of the Company shall have
the right to extend this Agreement on the same terms and conditions, upon
written notice from the Company to the Employee given at any time on or before
March 31, 1999 and March 31, 2000, respectively, for up to two (2) additional
periods of one year each. As used herein, the "Term" of this Agreement shall
include the initial two (2) year Term through April 30, 1999 and either or both
of the additional one (1) year extensions provided for herein.

             2. Termination For Cause. Anything contained in Section 1 of this
Part B to the contrary notwithstanding, this Agreement may be terminated at the
option of the Board of Directors of the Company (the "Board") for "Cause" (as
hereinafter defined), effective upon the giving of written notice of termination
to the Employee. As used herein, the term "Cause" shall mean and be limited to:

                                       3
<PAGE>   4
             (a) any act committed by the Employee against the Company, or any
of its Subsidiaries or divisions, constituting: (i) fraud, (ii) misappropriation
of corporate opportunity, breach of fiduciary duty or non-disclosure of a
conflict of interest, (iii) self-dealing, (iv) embezzlement of funds, (v) felony
conviction for conduct involving moral turpitude or other criminal conduct, or
(vi) the disregard by the Employee of the reasonable directions of the Board or
of the Chief Executive Officer of the Company; provided, that Employee has been
given written notice of such disregard and a reasonable opportunity to cure the
same; or

             (b) the breach or default by the Employee in the performance of any
material provision of this Agreement (including but not limited to Part D
below); provided, that Employee has been given written notice of such breach or
default, and a reasonable opportunity to cure the same; or

             (c) alcoholism or any other form of addiction which impairs the
Employee's ability to perform his duties hereunder.

        3. Death or Disability. Anything contained in Section 1 of this Part B
to the contrary notwithstanding, this Agreement may be terminated by the
Company; (i) upon the death of the Employee, or (ii) on thirty (30) days' prior
written notice to the Employee, in the event that the Employee shall be
physically or mentally disabled or impaired so as to prevent him from continuing
the normal and proper performance of his duties and responsibilities hereunder
for a period of three (3) consecutive months. The initial determination as to
whether the Employee is disabled or impaired shall be made by the physician
regularly treating the condition causing the disability. The Company shall have
the right to require the Employee to be examined by a physician duly licensed to
practice medicine in the State in which the


                                       4
<PAGE>   5
Employee has his primary residence to determine such physician's opinion as to
the Employee's disability. If such physician's opinion differs from that of the
physician treating the Employee, or a physician thereafter retained by the
Employee, they shall forthwith select a third physician so licensed whose
opinion, after examination and review of available information, shall be
conclusive and binding upon all parties hereto. All costs of the physician
regularly treating or thereafter retained by the Employee shall be paid by the
Employee. All costs of the physician retained by the Company shall be paid by
the Company. If a third physician is required, then the costs of that physician
shall be paid by the Company.

        4. No Further Obligations. Upon any termination of this Agreement by the
Company for "Cause" pursuant to Section 2 of this Part B, or by reason of the
Employee's death or disability pursuant to Section 3 of this Part B, neither the
Company nor any Subsidiary or division thereof shall be liable for or be
required to pay to the Employee any further remuneration, compensation or other
benefits hereunder; provided, however, that in the event of termination due to
disability, the Company shall pay the Employee the benefits described in Section
8 of Part C.

        5. Breach of Agreement by Company. In the event the Company or the
Corporations materially breach this Agreement or are in default hereunder,
Employee may resign by written notice to the Company, provided that Employee
shall have given written notice to the Company of the alleged breach or default
and given the Company a reasonable opportunity to cure the alleged breach or
default. In the event that the Employee resigns pursuant to this Section 5 of
this Part B, he shall be entitled to the benefits described in Section 8 of
Part C.

$25,000 per year. Sums set forth in this Section 4 of Part C shall be increased
by not less than 5% per year during the Term of this Agreement. For performance
significantly beyond the agreed-upon goals in the sole discretion and judgment
of the Chairman of the Board, the Company shall consider paying the Employee

to the Company and the Employee, and so as not to unduly interfere with the
business of the Company. The Employee may carry over, to the next annual period

year of the term of this Agreement.

        7. Expenses. In addition to the compensation set forth above, throughout
the period of the Employee's employment hereunder, the Company shall also
reimburse the Employee or cause the Employee to be reimbursed, upon presentment
by the Employee to the Company of appropriate receipts and vouchers therefor,
for any reasonable business expenses incurred by the Employee in connection

the Company shall appoint Employee as a consultant (the "Consultant") to the

Agreement, and which have vested as of the date of Employee's termination as an
employee of the Company, will be deemed vested and will remain exercisable by
the Consultant and not subject to forfeiture as a result of the termination of
this Agreement. Notwithstanding the foregoing, any options to purchase stock of
the Company and the Subsidiaries which have been granted to Employee pursuant

or the subject Subsidiary, and shall be delivered to the Company or the subject
Subsidiary (without the Employee retaining any copies, components or records

D be fully severable, and in the event that any of the foregoing restrictions,
or any portion of the foregoing restrictions, shall be deemed contrary to law,

reduced form, such

                                       12

provisions shall then be enforceable), and any other of the foregoing
restrictions shall be unaffected and shall remain in full force and effect.

in the event of any breach or threatened breach by the Employee of the
provisions of this Part D, the Company will suffer irreparable harm and will not
have an adequate remedy at law. Accordingly, in the event of any such breach or
threatened breach, the Company may seek and obtain appropriate equitable relief
to restrain or enjoin such breach or threatened breach and/or to compel
compliance herewith.

Company of its duties and obligations to the Employee hereunder, without the
