Term and thereafter subject to such increases, if any, as may be approved by and
in the discretion of the Board of Directors of Employer provided, however, that
                                                        --------  -------
in any event on each anniversary of the date of this Agreement, the Base Salary
shall be adjusted and increased as against the Base Salary prior to such
adjustment by the same percentage as the rise in the Consumer Price Index for
the New York region maintained by the Bureau of Labor Statistics for the
preceding calendar year. The 

 
Base Salary shall be payable twice monthly.

          4.   Employer may pay to Executive bonuses (in cash or stock options)

programs which are currently afforded or during the term of this Agreement are

insurance, health, hospital, dental, major medical, life and disability
insurance and stock option plans or other similar fringe benefits on the same
terms as such benefits are available to executives of Employer generally.
Executive, at his option, may elect to receive from the Company, as an
alternative to health and insurance benefits as defined in this paragraph, an
amount equal to the amount that the Company would have paid to provide such
benefits for Executive. Such amount will be paid and will be adjusted quarterly
for any changes in the cost of such coverage.

          7.   Executive will be entitled to four weeks vacation during the
Initial Term and any renewal term of this Agreement. Executive, at his option,
shall be entitled to receive payment for any unused vacation or accrue such
vacation time.

          8.   During the Initial Term and any renewal term, Employer will pay
Executive a travel allowance equal to the then-current maximum allowable rate

actually driven by Executive in performance of Executive's services under this
Agreement.

          9.   (a)  Employer will obtain life insurance coverage, (assuming
Executive is insurable) on the life of and for the benefit of Executive in an

          10.  In the event of Executive's death during the term of this
Agreement, this Agreement shall terminate immediately, provided, however, that
Executive's legal representatives shall be entitled to receive within 60 days

Agreement, in addition to any other amounts payable to Executive hereunder, the
Base Salary which would otherwise be due Executive until the expiration of the
month of employment during which the termination occurred plus six additional
months of the Base Salary in effect on the date of such termination. If, prior
to the date specified on such notice, Executive's illness or incapacity shall
have terminated and Executive shall have taken up the performance of Executive's
duties hereunder, Executive shall be entitled to resume Executive's employment
hereunder as though such notice had not been given. Employer's Board of
Directors shall determine in good faith, upon consideration of medical evidence
satisfactory to it, whether Executive by reason of physical or mental disability
shall be unable to perform the services required of Executive hereunder.

          12.  If Employer shall terminate Executive's employment hereunder for
Cause, as hereinafter defined, Employer will pay to Executive within ten days
after the termination of this Agreement an amount equal to the amount which
Executive would have earned as the Base Salary hereunder through the end of the
then current month in which such termination or departure occurred plus three
additional months of the Base Salary in effect on the date of such termination.
Cause shall mean a conviction of a felony directly and materially affecting
Employer.

          13.  If Executive's employment shall terminate for any reason other

amounts payable to Executive hereunder, the base salary due Executive through
the termination date plus an amount equal to six months of the 

                                      -3-

 
Executives base salary then in effect. This provision of the agreement shall be
operative regardless of who terminates the agreement or how long the agreement
has been in effect.

          14.  Executive covenants and agrees with Employer that Executive has
not and will not, during Executive's employment with Employer and thereafter,
directly or indirectly, use, communicate, disclose or disseminate to anyone
(except to the extent reasonably necessary for Executive to perform his duties
hereunder, except as required by law or except if generally available to the
public otherwise than through use, communication, disclosure or dissemination by
the Executive) any materials, documents or records containing confidential
information concerning the businesses or affairs of Employer or of any of its
affiliates or subsidiaries which Executive may have acquired in the course of or
as incident to Executive's employment or prior dealings with Employer or with
any of its affiliates or subsidiaries, including, without limitation, customer
lists, business or trade secrets of, or methods or techniques used by Employer
of any of its affiliates or subsidiaries in or about their respective
businesses, or any information whatsoever concerning the customers or suppliers
of any of them.

          15.  Executive covenants and agrees with Employer that Executive has
not, and will not during Executive's employment with Employer and for a period
of six months after the termination of Executive's employment with Employer, in
any manner, directly or indirectly, (i) induce or attempt to influence any
present or future officer, employee, lessor, lessee, licensor, licensee or agent
of Employers or its subsidiaries or its affiliates to leave its respective
employ or solicit or divert or service any customers or clients of Employer or
its subsidiaries or its affiliates or (ii) alone or as a partner, officer,
director, employee, consultant or stockholder (except for ownership of no more
than 1% of the capital stock) of any corporation, partnership or other entity be
competitive with the business of Employer or its subsidiaries or affiliates. For
purposes of subdivision (ii) above of this paragraph 16, a business shall be
presumed to be competitive if it conducts in whole or in part anywhere in the
United States any business in which Employer, its subsidiaries or affiliates has
engaged in or engages in during the term of Executive's employment with Employer
or which Employer, its subsidiaries or affiliates contemplated engaging in
during the term of this Agreement and began engaging in within six months
subsequent to the termination of this Agreement.

          16.  Employer acknowledges that Executive has substantial interest and
activities in the medical field. Nothing herein shall restrict or otherwise
limit Executive from managing Executive's private investments or conducting
activities which are not competitive with the businesses of Employer. Executive
shall be permitted to serve as a director of companies which are not competitive
with the businesses of Employer, so long as such services do not interfere with
the performance of Executive's duties under this Agreement.

          17.  Executive acknowledges that the remedy at law for any breach or
threatened breach by the Executive of the covenants contained in paragraphs 15
and 16, would be wholly inadequate, and therefore the Employer or its
subsidiaries or its affiliates shall be entitled to preliminary and permanent
injunctive relief and specific performance thereof. Paragraphs 15 and 16,
constitute independent and separable covenants that shall be enforceable

                                      -4-

 
notwithstanding rights or remedies that the Employer or its subsidiaries or its
affiliates may have under any other provision of this Agreement, or otherwise.
If any or all of the provisions of paragraph 15 and 16 are held to be
unenforceable for any reason whatsoever, it shall not in any way invalidate or
affect the remainder or this Agreement which shall remain in full force and
effect. If the period of time or geographical areas specified in paragraphs 15
and 16 are determined to be unreasonable in any judicial proceeding, the period
of time or areas of restriction shall be reduced so that this Agreement may be
enforced in such areas and during such period of time as shall be determined to
be reasonable.

          18.  The waiver by either party of a breach of any provision of this
Agreement shall not operate as or be construed as a waiver of any subsequent
breach thereof.

          19.  Any and all notices referred to herein shall be sufficient if
furnished in writing and sent by certified mail, return receipt requested, to
the respective parties at the addresses set forth below, or such other address
as either party may from time to time designate in writing.

each of which shall be an original, but all of which together shall constitute
one and the same Agreement.

held for any reason to be unenforceable, the remainder of this Agreement shall
nevertheless remain in full force and effect.
