         Subject to Section 6 hereof, the Executive hereby agrees that the

it is suffering irreparable injury, then the non-breaching party shall be
entitled to institute legal proceedings to enforce the specific performance of
this Agreement by the breaching party and to enjoin the breaching party from any
further violation of the Agreement and to exercise such remedies cumulatively or
in conjunction with all other rights and remedies provided by law and not
otherwise limited by this Agreement. The parties acknowledge, however, that the
remedies at law for any breach of the provisions of Sections 5, 6, 7 or 8 may be
inadequate. In addition, in the event the covenants set forth in Sections 5, 7
or 8 shall be determined by any court of competent jurisdiction to be
unenforceable by reason of extending for too great a period of time or over too
great a geographical area, by reason of being too restrictive or expansive, or
by constituting an unlawful restraint of trade in any other respect, each such
covenant shall be interpreted to extend over the maximum period of time and over
a maximum geographical area for which it may be enforceable, and to the maximum
extent in all other respects as to which it may be enforceable, and enforced as
so interpreted, all as determined by such court in such action.

                           including no trading from fifteen (15) days prior
                           the end of a fiscal quarter (December 31, March 31,
                           June 30 and September 30) through forty eight (48)
                           hours after the results of operations for the period
                           then ended are publicly released by the Company; and

                  c.       For twelve (12) months following the Effective Date,
                           in market transactions on any one trading day which
                           are reflected on NASDAQ (National Markets) and
                           constitute in the aggregate more than twelve (12%)
                           percent of that day's total trading volume
                           (including trades by Elfersy).

         (i)      Concurrently with the Effective Date, Mr. Elfersy will be
                  granted additional options to acquire One Hundred Thousand
                  (100,000) shares of common stock in eMD at a strike price of
                  $5.25 per share.

2.       All options to acquire shares of common stock of the Company,

         prior grants (the "Options"), will be delivered to Elfersy on or
         before the Effective Date and shall be made in accordance with all
         applicable laws, including but not limited to the requirement to

         options to purchase shares of the common stock of eMD shall be
         immediately exercisable through the fifth anniversary of the Effective
         Date; provided, however, that Elfersy's additional options to purchase

         Company at a strike price of $ 2.44 shall expire ninety (90) days from
         the Effective Date. The Options shall be converted to a successor
         company's stock in the event of a merger, change in control or
         transaction in which the Company is not the surviving entity, and

         Options) to reflect the effect of any stock dividend or split,
         recapitalization, reinvestments, extraordinary dividend and/or
         transfer with each such adjustment becoming effective upon the date of
         the related event. The Company will give Elfersy prior written notice
         of the record date of any such event (or if no record date is
         established, of the event) and of the prospective adjustment, which
         will result from such event.

3.       Concurrently with this Agreement, Elfersy agrees to execute such
         additional documents as may be reasonably requested by the Company to
         transition operational responsibilities, including assignment of
         patent and/or inventorship rights on patents and/or patentable
         technology developed for the Company

<PAGE>   4

         during the term and within the scope of his employment using company
         resources, up to and including the Effective Date; provided, however,
         that the Company expressly acknowledges that Elfersy may subsequently
         develop, during the term of this Agreement, patentable or potentially
         patentable technology in which the Company shall have no right of
         ownership, title or interest.

4.       For a period of forty two (42) months from the Effective Date, Elfersy
         agrees to make himself reasonably available at mutually acceptable
         times to advise and consult with the Company with respect to future
         developments and technical advances concerning anti-microbials and
         organo-silanos (which may or may not be related to current work or
         projects of the Company). Elfersy shall provide the Company Board of
         Directors with written quarterly reports, if requested to do so by the
         Board, concerning such future developments and technical advances in
         January, April and July 2001. Failure of Elfersy to satisfactorily
         perform under this paragraph 4 shall not be treated as a breach by
         Elfersy of this Agreement or provide grounds for the Company to
         terminate or diminish any payment to or benefit provided or to be
         provided to Elfersy or his family or heirs under this Agreement.

5.       Except for claims arising after the Effective Date as to the
         performance of this Agreement and its concomitant obligations, Elfersy
         hereby fully and finally releases, remises, acquits, forgives and
         forever discharges the Company and its affiliates, subsidiaries,
         officers, directors, shareholders, employees, agents, attorneys,
         representatives, successors and assigns, and any of their respective
         directors, officers, shareholders, agents, attorneys, employees or
         representatives from any and all actions, suits, prosecutions, claims,
         liabilities, damages or other legal or equitable remedies, whether
         known or unknown, foreseeable or unforeseeable, arising or claimed to

         or any agreements, undertakings, commitments, representations,
         disclosures, failures to disclose, occurrences, actions, failures to
         act, breaches or defaults directly or indirectly related thereto or

         unforeseeable, arising or claimed to arise from, or in connection
         with, Elfersy's employment by the Company or eMD or any agreements,
         undertakings, commitments, representations, disclosures, failures to
         disclose, occurrences, actions, failures to act, breaches or defaults
         directly or indirectly related thereto or arising therefrom.

7.       Company, eMD and Elfersy agree that they shall not engage in any
         communications, which shall disparage one another on interfere with
         their existing prospective business relationships. The Company and
         Elfersy shall issue a joint press release acceptable to other
         concerning the completion and terms of this Agreement.

8.       No failure or delay on the part of the Company or Elfersy in
         exercising any right, power or remedy hereunder shall operate as a
         waiver thereof, nor shall any single or partial exercise of any such
         right, power or remedy preclude any other or further exercise thereof
         or the exercise of any other right, power or remedy.

         conflicts of laws thereof.

12.      Any provision of this Agreement which is prohibited or unenforceable
         in any jurisdiction shall, as to such jurisdiction, be ineffective to
         the extent of such prohibition or unenforceability only without
         invalidating the remaining provisions hereof or affecting the validity
         or enforceability of such provision in any other jurisdiction.

13.      This Agreement constitutes the entire agreement between The Company
         and Elfersy with respect to the subject matter hereof and there are no
         promises or undertakings with respect thereto not expressly set forth
         herein.

14.      To the fullest extent permitted by law, the Company and eMD shall
         forever indemnify, protect and hold harmless Elfersy from and against
         any claim, suit, action or proceeding, whether civil, criminal,
         administrative or investigative, which is made or threatened to be
         made, against Elfersy by reason of the fact that he was a director or
         officer of the Company and/or eMD or any subsidiary thereof or was
         serving at the request of the Company and/or eMD as a director,
         officer or trustee of, or in any similar capacity with any other
         entity, which indemnification shall include without limitation payment
         of any expenses (including attorneys' fees), judgments, fines and
         amounts paid in settlement actually and reasonably incurred by him or
         on his behalf in connection with any such claim, action, suit
         proceeding, and any appeal therefrom or investigation thereof. Such
         payment by the Company and/or eMD of said expenses shall be made on
         behalf of Elfersy when incurred by or on behalf of Elfersy, whether or
         not in advance of the final disposition of the matter, subject only to
         Elfersy providing the Company and/or eMD with a written undertaking to
         repay such payment(s) and/or expense(s) if it is finally determined by
         a Court of competent jurisdiction that Elfersy is not entitled to
         indemnification as a matter of law with respect to such matter.
