COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934

requires the Company's directors and executive officers, and persons who own
more than 10% of a registered class of the Company's equity securities, to file
with the SEC initial reports of ownership and reports of changes in ownership
of Common Stock and other equity securities of the Company.  Officers,
directors and greater than 10% stockholders are required by SEC regulation to
furnish the Company with copies of all Section 16(a) forms they file.

         To the Company's knowledge, based solely on a review of the copies of
such reports furnished to the Company and written representations that no other
reports were required, during the fiscal year ended December 31, 1995, all
Section 16(a) filing requirements applicable to its officers, directors and
greater than 10% beneficial owners were complied with, except that the initial
transaction report of Niquette Hunt was inadvertently filed late.

ITEM 11 - EXECUTIVE COMPENSATION.

COMPENSATION OF DIRECTORS

         Each non-employee director of the Company receives a per-meeting fee of
$750.  In the fiscal year ended December 31, 1996, the total compensation paid
to non-employee directors was $26,000.  The members of the Board of Directors
are also eligible for reimbursement for their expenses incurred in connection
with attendance at Board meetings in accordance with Company policy.

         Each non-employee director of the Company receives stock options
granted under the 1992 Non-Employee Directors' Stock Option Plan (the
"Directors' Plan").  Only non-employee directors of the Company or an affiliate
of such directors (as defined in the Internal Revenue Code of 1986, as amended
(the "Code")) are eligible to receive options under the Directors' Plan.
Options granted under the Directors' Plan are intended by the Company not to
qualify as incentive stock options under the Code.

         Option grants under the Directors' Plan are non-discretionary.  On
January 2 of each year (or the next business day should such date be a legal
holiday), each non-employee director is automatically granted under the
Directors' Plan, without any further action by the Company, the Board of
Directors or the stockholders of the Company, an option to purchase 2,000 shares
of Common Stock of the Company.  In addition, each person who first becomes a
non-employee director is granted an option to purchase 5,000 shares of Common
Stock of the Company upon the date of election to the Board.  No other options
may be granted at any time under the Directors' Plan.  The exercise price of the
options granted under the Directors' Plan is 100% of the fair market value of
the Common Stock subject to the option on the date of the option grant.  Options
granted under the Directors' Plan become exercisable in four equal installments
beginning on the first anniversary of the grant of the option.  Such vesting is
conditioned upon continued service as a director of the Company.  The term of
options granted under the Directors' Plan is 10 years.





                                       5.
<PAGE>   6
         During the last fiscal year, options covering 2,000 shares were granted
to each of Messrs. Gin, Jozoff, Rubinfien, Russell, and Stroy at an exercise
price per share of $1.44, the fair market value of such Common Stock on the date
of the grant, and 5,000 shares to Mr. Kiley, at an exercise price per share of
$2.47, the fair market value of such Common Stock on the date of the grant.  As
of March 31, 1997, no options had been exercised under the Directors' Plan.
Directors are also eligible to receive certain stock awards, such as stock
bonuses, stock appreciation rights, and rights to purchase restricted stock,
under the Company's 1993 Equity Incentive Plan (the "1993 Plan").  As of March
31, 1997, no stock awards had been granted to directors under the 1993 Plan.

         In October 1995, Mr. Jozoff entered into a consulting agreement with
the Company and was granted a non-statutory stock option under the Company's
1993 Equity Incentive Plan to purchase 30,000 shares of Common Stock at a
price of $1.62 per share, equal to the fair market value of the Common Stock
on the date of the grant.  These options become exercisable in six equal monthly
installments beginning one month from the date of the grant.  In September 1996,
Mr. Kiley entered into a consulting agreement with the Company and was granted a
non-statutory stock option under the Company's 1993 Equity Incentive Plan to
purchase 5,000 shares of Common Stock at a price of $2.47 per share, equal to
the fair market value of the Common Stock of the date of the grant. These
options became exercisable in eight equal quarterly installments beginning three
months from the date of the grant.

         Directors who are employees of the Company are not separately
compensated for their service as directors.

(1)     Based on an aggregate of options to purchase 456,916 shares of the
        Company's Common Stock granted to employees of the Company in fiscal
        1996, including the Named Executive Officers.

(2)     The options in this table have exercise prices equal to the fair market
        value of the Common Stock on the date of grant.  Options vest 25% on the
        first anniversary of the date of grant, and 2.0833% per month thereafter
        for the next 36 months. In the event of a decline in value of the
        Company's Common Stock, the Board has the authority to offer employees
        the opportunity to replace outstanding higher priced options, whether
        incentive or non-statutory, with new lower priced options.

(3)     The potential realizable value is based on the term of the option at
        the time of grant (10 years).  The potential realizable value is
        calculated by assuming the stock price on the date of grant appreciates
        at the individual rate for the entire term of the option, and that the
        option is exercised and sold on the last day of its term at the
        appreciated price.  These amounts represent certain assumed rates of
        appreciation, in accordance with the rules of the SEC, and do not
        reflect the Company's estimate or projection of future stock price
        performance.  Actual gains, if any, are dependent on the actual future
        performance of the Company's Common Stock and no gain to the optionee
        is possible unless the stock price increases over the option term,
        which will benefit all stockholders.

EMPLOYMENT AGREEMENTS

    In February 1996, the Company and Dr. Singh entered into an employment
agreement providing that Dr. Singh's salary be set at $15,333 per month.  The
agreement provides that if Dr. Singh's employment is terminated without cause,
he will receive up to 12 months salary continuation.  In addition, in the event
of such termination, all of the Company's Common Stock held by Dr. Singh will
be free of any repurchase options in favor of the Company, and all of Dr.
Singh's options will become fully vested and exercisable.  For a period of one
year following such termination, the Company has also agreed to reimburse Dr.
Singh for any medical or other employee insurance coverage that he elects to
continue.
