OPTION PLANS AND GRANTS

    An aggregate of 250,000 shares of Common Stock are reserved for issuance or
available for grant under the Company's 1991 Employee Stock Option Plan (the
"1991 Employee Plan").  Options granted under the 1991 Employee Plan are
intended to qualify as incentive stock options within the meaning of Section 422
of the Internal Revenue Code of 1986, as amended (the "Code").  The 1991
Employee Plan is administered in all respects by a committee composed of at
least two non-employee members of the Company's Board of Directors who are
designated by the Board (the "Stock Option Committee").  The Stock Option
Committee may determine the employees to whom options are to be granted and the
number of shares subject to each option.  Under the terms of the 1991 Employee
Plan, all employees of the Company or subsidiaries of the Company are eligible
for option grants.  The option exercise 

                                           -7-


price of options granted under the 1991 Employee Plan is fixed by the Stock
Option Committee but must be no less than 100% of the fair market value of the
shares of Common Stock subject to the option at the time of grant, except that
in the case of an employee who possesses more than 10% of the total combined
voting power of all classes of stock of the Company (a "10% Holder"), the
exercise price must be no less than 110% of said fair market value.  Options may
be exercised by the payment in full in cash or by the tendering or cashless
exchange of shares of Common Stock or of options to acquire shares of Common
Stock having a fair market value, as determined by the Stock Option Committee,
equal to the option exercise price.  Options granted under the 1991 Employee
Plan may not be exercised more than ten years after the date of grant, five
years in the case of an incentive stock option granted to a 10% Holder.  All
currently outstanding options have a term of five years, as of July 31, 1997. 
At July 31, 1997, options to purchase 139,750 shares of Common Stock at prices
between $3.50 and $8.75 per share were outstanding under the 1991 Employee Plan,
and 70,625 shares were available for grant under the 1991 Employee Plan.

    An aggregate of 200,000 shares of Common Stock are reserved for issuance or
available for grant under the Company's 1991 Directors' Stock Option Plan (the
"Directors' Plan").  Options granted under the Directors' Plan do not qualify as
incentive stock options within the meaning of Section 422 of the Code.  The
Directors' Plan provides for the automatic grant to each of the Company's
directors of options to purchase 1,000 shares of Common Stock on the last
business day of the Company's fiscal year.  In addition, an option to purchase
500 shares of Common Stock is granted automatically on the last business day of
each fiscal quarter to each director (exclusive of Messrs. Diker, Reilly and
Dornbush and any other director who serves as an officer or employee of the
Company) provided that the director attended any regularly scheduled meeting of
the Board, if any, held during such quarter.  Each such option grant is at an
exercise price equal to the fair market value of the Common Stock on the date of
grant and has a ten year term (but in no event more than three months following
the optionee's ceasing to serve as a director of the Company).  The fiscal year
options are exercisable in two equal annual installments commencing on the first
anniversary of the grant thereof and the quarterly options are exercisable in
full immediately.  At July 31, 1997, options to purchase 126,000 shares of
Common Stock at prices between $2.00 and $10.25 per share were outstanding under
the Directors' Plan, and 24,000 shares were available for grant under the
Directors' Plan.

    An aggregate of 200,000 shares of Common Stock are reserved for issuance or
available for grant under the Company's 1997 Employee Stock Option Plan approved
by the Company's Board of 

                                           -8-


Directors on October 16, 1997 (the "1997 Employee Plan").  Options granted under
the 1997 Employee Plan are generally intended to qualify as incentive stock
options within the meaning of Section 422 of the Code.  The 1997 Employee Plan
is administered in all respects by the Stock Option Committee.  The Stock Option
Committee may determine the employees to whom options are to be granted and the
number of shares subject to each option.  Under the terms of the 1997 Employee
Plan, all employees of the Company or subsidiaries of the Company are eligible
for option grants.  The option exercise price of options granted under the 1997
Employee Plan is fixed by the Stock Option Committee but must be no less than
100% of the fair market value of the shares of Common Stock subject to the
option at the time of grant, except that in the case of a 10% Holder, the
exercise price for incentive stock options must be no less than 110% of said
fair market value.  Options may be exercised by the payment in full in cash or
by tendering or cashless exchange of shares of Common Stock or of options to
acquire shares of Common Stock having a fair market value, as determined by the
Stock Option Committee, equal to the option exercise price.  Options granted
under the 1997 Employee Plan may not be exercised more than ten years after the
date of grant, five years in the case of an incentive stock option granted to a
10% Holder.  To date, no options have been granted under the 1997 Employee Plan.
The 1997 Employee Plan has been adopted by the Board of Directors and is subject
to shareholder approval.

    The Company also has outstanding options granted by MediVators prior to the
Merger under the MediVators 1991 Stock Option Plan (the "MediVators Plan") which
became fully exercisable as a result of the Merger.  At July 31, 1997, options
to purchase 61,131 shares of Common Stock at prices between $6.08 and $8.27 per
share were outstanding under the MediVators Plan.  No future options will be
granted under the MediVators Plan. 

    In June 1990, Mr. Reilly was granted a ten-year non-plan option to purchase
139,815 shares of Common Stock at an exercise price of $1.75 per share.  This
option is exercisable in full.  In addition, in July 1990, Mr. Reilly was
granted a ten-year non-plan option to purchase 50,000 shares at an exercise
price of $1.875 per share.  This option is exercisable in full.

    In December 1994, Mr. Barbanell was granted a five-year non-plan option to
purchase 25,000 shares of Common Stock at an exercise price of $3.75 per share. 
This option is currently exercisable in full and expires in December 1999.

    In October 1996, Mr. Diker was granted a ten-year non-plan option to
purchase 50,000 shares of Common Stock at an exercise price of $7.375 per share.
This option is exercisable in three equal annual installments beginning October
1996.  In addition, in October 1997, Mr. Diker was granted a ten-year non-plan
option to purchase 50,000 shares of Common Stock at an exercise price of $7.00
per share.  This option is exercisable in three 

                                           -9-


equal annual installments beginning October 1997.

DIRECTOR COMPENSATION

    Directors who are not officers of the Company were paid director's fees of
$500 per meeting attended, plus expenses.  Under the 1991 Directors' Stock
Option Plan, directors who are not officers of the Company are automatically
granted quarterly options to purchase 500 shares of Common Stock, provided that
the director attended any regularly scheduled meeting of the Board, if any, held
during such fiscal year quarter.  Mr. Dornbush, who is both an officer and
director of the Company (and who thereby does not receive said quarterly option
grant) is granted a non-plan option to purchase 500 shares of Common Stock for
each such meeting attended by Mr. Dornbush.  In addition, under the 1991
Directors' Stock Option Plan, all directors are automatically granted annual
options to purchase 1,000 shares of Common Stock at the fiscal year end.

COMPENSATION COMMITTEE INTERLOCKS
AND INSIDER PARTICIPATION

    No officer of the Company served on the Company's compensation committee
during its last fiscal year. James P. Reilly, the President and Chief Executive
Officer of the Company, however, participated in deliberations concerning
executive compensation, except with respect to his own compensation.
