(1)      These options were granted under the Company's 1993 Stock Option Plan
         and have a term of ten years, subject to earlier termination in certain
         events. See "Employment Agreements." The options are fully vested.

(2)      The potential realizable values are based on an assumption that the
         stock price of the Common Stock starts equal to the exercise price
         shown for the particular option grant and appreciates at the annual
         rate shown (compounded annually) from the date of grant until the end
         of the term of the option. These amounts are reported net of the option
         exercise price, but before any taxes associated with exercise or
         subsequent sale of the underlying stock. The actual value, if any, an
         option holder may realize will be a function of the extent to which the
         stock price exceeds the exercise price on the date the option is
         exercised and also will depend on the option holder's continued
         employment through the vesting period. The actual value to be realized
         by the option holder may be greater or less than the values estimated
         in this table.

EMPLOYMENT AGREEMENTS

         On June 4 , 1997, the Company entered into an employment agreement with
Richard J. DePiano as the Chairman and Chief Executive Officer of the Company.
The term of the employment agreement commenced on March 1, 1997 and shall
continue through February 28, 1998 subject to any extensions that may be entered
upon the written agreement of the Company and Mr. DePiano. The agreement
provides for a base salary of $240,000 per year plus incentive compensation in
the form of a cash bonus to be paid by the Company to Mr. DePiano in the event
the Company has entered into a sale, license or other transfer of all or a
substantial portion of the assets of the Company, a merger or consolidation of
the Company or a sale of all or a substantial portion of the Company's capital
stock. The bonus to be paid to Mr. DePiano shall be equal to 10% of the increase
in the market capitalization of the Company as a result of any of the
aforementioned transactions from March 1, 1997 to the close of business on the
date on which Mr. DePiano's employment with the Company terminates; provided,
however, that the minimum bonus to be paid to Mr. DePiano as the result of the
Company entering into any of the aforementioned transactions shall be $250,000.
The agreement also provides that the amount of the bonus is to be reduced by an
amount equal to the appreciation value of the stock options granted to Mr.
DePiano that have theretofore been exercised or that are exercisable. Under the
terms of the employment agreement, Mr. DePiano received options to purchase
450,000 shares of the Company's Common Stock. The options granted to Mr. DePiano
are fully vested but terminate upon the payment of his aforementioned incentive
compensation. The agreement also provides for health and long term disability
insurance and other fringe benefits as well as an automobile allowance of $800
per month.

         John T. Rich entered into an employment agreement with EOI in January
1990 that, as amended in January 1990 and September 1995, provides, among other
things, for annual salary at a rate established by the Company's Board of
Directors which is currently set as $119,000 per annum. Mr. Rich's employment
agreement was assumed by the Company in connection with the Assets Sale and
Purchase Agreement dated February 12, 1996 (the "Asset Sale and Purchase"),
pursuant to which EOI transferred substantially all of its assets and certain
liabilities to the Company in consideration of the issuance to EOI of 4,770,772
shares of the Common Stock of the Company. The agreement also provides for
health, life and long-term disability insurance and other fringe benefits. If
Mr. Rich is terminated without cause, the agreement provides for the
continuation of Mr. Rich's salary and fringe benefits for one year after
termination. Under the agreement, Mr. Rich was also granted options to purchase
up to 50,000 shares of the EOI's Common Stock at an exercise price per share of
$.25. The options are fully vested and currently exercisable. The employment
agreement expires in January 1998.

         Ronald L. Hueneke entered into an employment agreement with EOI in
October of 1991 that provides for annual salary at a rate established by the
Company's Board of Directors which is currently set as $105,000 per annum. Mr.
Hueneke's employment agreement was assumed by the Company in connection with the
Asset Sale and Purchase. The agreement also provides for health, life and
long-term disability insurance and other fringe benefits. In addition, the
agreement provided for incentive compensation equal to 3 1/3% of the gross sales
derived from the sale by Mr. Hueneke of certain products during the initial term
of the employment agreement. Under the agreement, Mr. Hueneke was also granted
options to purchase up to 75,000 shares of the EOI's Common Stock at an exercise
price per share of $1.00. The options are fully vested and currently
exercisable. The employment agreement, which had an initial term of five years,
renews automatically from year to year unless either party notifies the other in
writing at least 90 days prior to the expiration of the then current term of its
determination not to renew the agreement.

         Sterling C. Johnson entered into an employment agreement with EOI in
1989 that, as amended in January 1991 and January 1995, provided for annual
compensation in the amount of $154,000. In connection with the Assets Sale and
Purchase, Mr. Johnson's employment agreement was assumed by the Company,
including EOI's obligation to pay $60,000 in earned but unpaid compensation to
Mr. Johnson. Mr. Johnson's agreement was for a


                                       5
<PAGE>   6
three-year term ending in December 1997 and renewed automatically for successive
one-year periods unless either party notified the other in writing at least 90
days prior to the expiration date. The agreement provided for health, life and
long term disability insurance and other fringe benefits as well as
reimbursement of the costs associated with the lease of an automobile not in
excess of $500 per month. The agreement provided for severance payments, in the
event of termination without cause, equal to Mr. Johnson's salary and fringe
benefits for one year. Mr. Johnson was granted options to purchase up to 300,000
shares of EOI common stock at an exercise price per share of $.01. The options
were exercised. Under the terms of his employment agreement, the Company was
obligated to reimburse Mr. Johnson for any withholding tax obligation and the
tax on such reimbursement in the event Mr. Johnson exercised the options.
Effective April 30, 1997, Mr. Johnson stepped down from the office of President
and Chief Operating Officer. In connection therewith, the Company made payments
to Mr. Johnson in fiscal year 1997 of $23,697 in severance payments and $13,920
in accrued vacation. The Company will have paid to Mr. Johnson the balance of
all outstanding severance-related expenses, or approximately $150,000, by the
end of April 1998.

COMPENSATION OF DIRECTORS
Messrs. Johnson, Dodick and Federman are paid directors' fees of $2,000 for
each board meeting attended in person and $500 for each Committee meeting or
meeting attended telephonically. Mr. Kunze is paid a monthly directors' fee of
$4,000 per month. In addition, directors are reimbursed for expenses incurred
in connection with attending meetings. See "Executive Officers--Executive

Additionally, certain of the reporting persons share beneficial ownership of
certain securities of the Company. Any securities as to which beneficial
ownership is shared are set forth on the table below as beneficially owned by
each person to whom beneficial ownership may be attributed. See the footnotes to

         EOI. Additionally, Messrs. Johnson and Rich (the Company's current Vice
         President of Finance and Administration and the Secretary) serve as the

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         On February 12, 1996, the Company acquired substantially all of the
assets and certain of the liabilities of EOI, pursuant to an Assets Sale and
Purchase Agreement, in exchange for 4,770,772 shares of the Company's Common
Stock. The total estimated cost of the acquisition was $8,900,000, including
liabilities assumed (which includes the assumption of costs associated with
certain litigation involving EOI) of $1,016,340 and estimated transaction costs
of approximately $928,000. The acquisition was accounted for using the purchase
method of accounting and included the acquisition of accounts receivable,
inventories, equipment and various other tangible and intangible assets. The
total purchase price over the fair value of net assets acquired approximates
$4,100,000 and is being amortized over a ten-year period. Another $1,000,000 of
the purchase price was assigned to in-process technology and was charged to
operations immediately following the acquisition. As disclosed elsewhere herein,
Messrs. Johnson, DePiano, Dodick and Federman were at the time of the
acquisition, and continue to be, members of the Board of Directors of EOI.
Messrs. Johnson and Rich, the Company's former President/Chief Executive
Officer, Chief Operating Officer and Vice President, Finance and
Administration/Secretary, respectively, serve in similar executive level
management positions with EOI. Ronald L. Hueneke, a Vice President of the
Company and General Manager of its Trek Division, served in the same position
with EOI prior to the consummation of the Asset Acquisition. EOI is the
beneficial owner of 42.2% of the outstanding Common Stock of the Company and
each individual named in this paragraph is a shareholder of EOI.

         Jay L. Federman, M.D., a Director, together with two individuals
unaffiliated with the Company, entered into a Development, Assignment and
License Agreement with the Company dated September 11, 1992. Under this
agreement, the Company has agreed to pay royalties to Dr. Federman and the two
unaffiliated individuals on sales of the Company's Iris Expander and related
products. Generally, the agreement provides for quarterly royalty payments of
10% of net sales, for sales by the Company, and the greater of 5% of net sales
or 50% of royalty payments received by the Company, for sales by sublicensees of
the Company, in countries where a valid patent for the product has issued. For
sales in countries where a valid patent has not issued, royalty payments equal
to one-half of the foregoing rates are required. As of the date hereof, the Iris
Expander is still under development. Therefore, no royalty payments have been
made to Dr. Federman or the other individuals that are parties to the
Development, Assignment and License Agreement.

         Commencing November 17, 1994, upon the exercise of any Class A
Redeemable Common Stock Purchase Warrant or Class B Redeemable Common Stock
Purchase Warrant (a "Warrant"), to the extent not inconsistent with the
guidelines of the NASD and the rules and regulations of the Securities and
Exchange Commission (the "Commission"), the Company has agreed to pay D. Blech &
Company, Incorporated ("Blech"), except in certain limited circumstances, a fee
of 5% of the exercise price of such Warrant if (i) the market price of the
Common Stock is greater than the exercise price of such Warrant on the date of
exercise; (ii) on the date of exercise Blech is a registered broker-dealer and
its registration has not been suspended; (iii) such Warrant is not held in a
discretionary account; and (iv) the solicitation of such Warrant was not in
violation of Rule 10b-6 promulgated under the Securities Exchange Act of 1934,
as amended. The Company has agreed not to solicit the exercise of any Warrant
other than through Blech unless Blech is legally unable to solicit such exercise
or is prohibited from doing so by the rules of the NASD or otherwise, in which
event the Company may solicit such exercise, either itself or with the
assistance of a third party.

         In November 1993, the Company sold to Blech a transferable option (the
"Unit Purchase Option") to purchase up to 300,000 Units. The Unit Purchase
Option is exercisable for a period of four years, commencing November 17, 1994,
at an initial exercise price equal to $8.00 per Unit. The Units are identical in
all respects to Units issued in an underwritten public offering of Units made in
November and December of 1993, except that (i)


                                       8
<PAGE>   9
while the Warrants comprising such Units are held by Blech or certain
transferees of Blech, they are not redeemable by the Company and (ii) Warrants
comprising such Units are exercisable for the period commencing on November 17,
1993, and terminating at the close of business on November 24, 1994. The Unit
Purchase Option cannot be transferred, assigned or hypothecated prior to
November 24, 1994, except that it may be assigned, in whole or in part, to any
successor, officer or partner of Blech. The Unit Purchase Option contains
antidilution provisions providing for appropriate adjustment of the exercise
price and the number of Units which may be purchased upon exercise upon the
occurrence of certain events.

         The Company has agreed that it will, at its expense on any one occasion
during the four-year period commencing November 17, 1994, and on any one
additional occasion at the expense of the holders thereof during such period,
register the securities underlying, or issuable upon the exercise of the
securities underlying, the Unit Purchase Option at the request of holders of a
majority of the Units issued or issuable upon exercise of the Unit Purchase
Option (including shares of Common Stock issuable upon exercise of the Warrants
included in those Units). The Company has also agreed, during the seven-year
period commencing November 17, 1994, to register on a "piggyback" basis, on an
unlimited number of occasions, such securities whenever the Company files a
registration statement.

         For the life of Unit Purchase Option, the holders are given, at nominal
cost, the opportunity to profit from a rise in the market price for the
securities of the Company without assuming the risk of ownership, with a
resulting dilution in the interest of other security holders. As long as the
Unit Purchase Option remains unexercised, the terms under which the Company
could obtain additional capital may be adversely affected. Moreover, the holders
of the Unit Purchase Option may be expected to exercise such option at a time
when the Company would, in all likelihood, be able to obtain needed capital by
an offering of its securities on terms more favorable than those provided by the
Unit Purchase Option.
