5.1 BBWI shall be responsible for the preparation, filing, prosecution and
maintenance of U.S. patent applications and U.S. patents included in the
LICENSED INTELLECTUAL PROPERTY, that are incurred prior to the execution of the
Agreement. BBWI will continue to prepare, file, prosecute and maintain these

provided to BBWI. Documents received from any patent office or counsel's
analysis thereof shall be provided to BBWI promptly after receipt. If TETRIDYN
elects not to pay or continue to pay the out of pocket costs associated for such
LICENSED INTELLECTUAL PROPERTY, TETRIDYN shall notify BBWI within thirty (30)
days of TETRIDYN's decision and TETRIDYN shall thereafter be relieved of the
obligation to pay any additional costs regarding such LICENSED INTELLECTUAL
PROPERTY incurred after the receipt of such notice by BBWI. Such foreign patent
application or patent will thereupon cease to be LICENSED INTELLECTUAL PROPERTY
and BBWI will be free to license its rights to that particular foreign patent
application or patent to any other party on any terms.

                              Payments and Reports

6.1 TETRIDYN shall keep, and will cause each of its SUBLICENSEES, if any, to
keep detailed and accurate accounting records containing all information and
data necessary for determining performance and calculating all fees, royalties,
and royalty based payments payable to BBWI. Such accounting records, with all
necessary supporting information and data will, during all reasonable times for
the three (3) years following the end of the calendar year to which each

reasonable times by BWWI or its designee, and at BBWl's expense, for verifying
royalty reports or verifying TETRIDYN's compliance with this Agreement.

6.2 The amount of royalty due will be calculated semi-annually as of the end of
each ACCOUNTING PERIOD and will be paid in U.S. currency within sixty (60) days
from these dates. Conversion from any foreign currency will be at the rate of
exchange published in the Wall Street Journal for the business day closest to
the end of the applicable ACCOUNTING PERIOD. If no amount is accrued during any
ACCOUNTING PERIOD, TETRIDYN shall provide a written statement indicating such to
BBWI.

6.3 With each royalty payment, TETRIDYN shall deliver to BBWI a full and
accurate report to include the following information:

         (a)      Quantity (by country) of the LICENSED PRODUCTS sold, leased,

         (e)      Total royalties payable to BBWI.

6.4 Payments provided for in this Agreement, if overdue, will bear an annual
interest of three percent (3%) in excess of the "Prime Rate" published by "The
Wall Street Journal" at the time the payment is due, and for the time period
until payment is received by BBWI. Payments that become more than ninety (90)
days overdue will place TETRIDYN in default of this Agreement.

6.5 If this Agreement is terminated before all payments required up to the
termination date under this Agreement have been made, TETRIDYN shall submit a
termination report and pay to BBWI any remaining unpaid balance within, sixty
(60) days of the termination date even though the due date has not been reached.

6.6 No royalty shall be owed on any LICENSED PRODUCTS produced for, or under any
U.S. government agency contract pursuant to the government retained
non-exclusive license, but only to the extent that TETRIDYN can show that the U.
S. Government received a discount on LICENSED PRODUCTS sales, which discount is
equivalent or greater than the amount of any such royalty that would otherwise
be due. All sales for U.S. Government purposes must be reported under this
Article 6 and such reports will include (a) U.S. Government contract-number, (b)
identification of the U.S. Government Agency, and ( c) a description as to how
the benefits of the royalty free sale was passed on to the U.S. Government.

                            Performance Requirements

7.1 TETRIDYN shall itself, and through its SUBLICENSEES, use its best efforts to
develop and make LICENSED PRODUCTS commercially available by selling and
distributing LICENSED PRODUCTS and LICENSED MATERIALS throughout the LICENSED
TERRITORY.

7.2 TETRIDYN shall achieve the performance milestones indicated in Appendix B.
TETRIDYN shall notify BBWI in writing of completion of each specified
performance milestone within thirty (30) days of the completion date. If
TETRIDYN fails to achieve a performance milestone by the due date, a written
statement to that effect must be furnished. If TETRIDYN fails to achieve a
performance milestone BBWI has, at its sole discretion, the option thereafter,
to convert the exclusive license to a non-exclusive license or to terminate the
license by giving written notice to that effect.

                                    Article 8
                  Disclaimer of Warranties and Indemnification

supersedes all other agreements, express or implied, between the Parties
concerning the LICENSED INTELLECTUAL PROPERTY and LICENSED MATERIALS.

INTELLECTUAL PROPERTY will be substantially manufactured in the U.S. All
sublicense agreements will contain terms incorporating this requirement.

decisions.

         (a)      whether the proposed sublicensee has a business unit located

                  benefits will flow to the U.S. as a result of the sublicense;
                  and

         (b)      whether in sublicensing any entity subject to the control of a
                  foreign company or government, the foreign government permits
                  U.S. agencies, organizations or other persons to enter into
                  licensing agreements, and have policies to protect U.S.
                  intellectual property rights.

15.3 lf TETRIDYN determines that either of the above conditions in this Article
may possibly not be fulfilled, TETRIDYN, before entering into the sublicensing
agreement, must specifically inform BBWI of such, as well as comply with Article
4.1. BBWI shall use reasonable efforts to act on a request for approval within
thirty (30) days of receipt of the request for approval.

thereof, by negotiation between members of the management of each Party having
authority to settle any controversy or claim arising out of or relating to this
Agreement and/or by way of working through the Technology Transfer Ombudsman
Office of BBWI. If such efforts are not successful, the Parties shall then try
in good faith to settle such controversy or claim by mediation administered by
the American Arbitration Association under its then current Commercial Mediation

MODIFICATION TO LICENSE AGREEMENT NUMBER 02-LA-02

Dear Dave:

As a result of our review meeting held on April 10, 2002, our License Agreement,
number 02-LA-02, dated October 16, 2001, will be modified as described below.

Appendix B, paragraph B1 is deleted and replaced with the following paragraph.

         B1. TETRIDYN represents and warrants that it will meet the established
         financial objective of receiving financial or equivalent capital
         commitments recommended for a BBWI spinout company of One Million Five
         Hundred Thousand dollars (US $1,500,000). If BBWI determines that
         during the first twelve months period after the EFFECTIVE DATE,
         TETRIDYN does not have such amount of capitalization (using generally
         accepted accounting practices), then BBWI may, at its sole discretion,
         terminate this agreement by providing written notice to TETRIDYN.
         TETRIDYN agrees further that said capital would be used exclusively for
         normal business of a business entity engaged in commercialization of
         the Licensed Technology (as defined in Appendix A).

This will extend the financial review period to October 16, 2002. Based on
information presented by TetriDyn yesterday, we intend to review the funding
status again during mid- to late-July. At that midpoint review, BBWI will expect
to see substantial progress on the equity (capital) investment in TetriDyn as
discussed in our meeting.

Please indicate your agreement with this action by signing below and returning
one signed original to me.

Sincerely,

/s/ Lyman J. Frost                             Agreed: /s/ David Hempstead
