the other party's  Confidential Information that it exercises in protecting
its own Confidential Information and shall in any event take all reasonable
precautions to prevent the disclosure of Confidential Information to any
third party.  Except as otherwise provided herein, before disclosing
Confidential Information to a third party ("Recipient"), the disclosing
party shall obtain a written commitment from the Recipient to observe the
confidentiality provisions of this Section 5.  Each party acknowledges and
agrees that, in addition to any other available rights or remedies, a
disclosing party shall be entitled to specific performance, injunctive
relief and any other equitable remedy for the breach or default or
threatened breach or default of this Section 5 and waives any defense that
a remedy at law or damages is adequate.  In addition to the confidentiality
provisions described above, Inventor agrees to be bound by the
confidentiality provisions contained in Exhibit G attached hereto.  Neither
party shall publicize the terms of this Agreement without the prior written
consent of the other party (except as required in connection with any legal
proceeding or arbitration, as required by law, or to the extent reasonably
required in connection with any merger, acquisition, reorganization,
capital or financing transaction), but each party shall have the right to
publicize the existence of this Agreement.  Inventor shall have the right
to publish the results of any studies and/or trials in connection with the
Technology that confirms (as opposed to that contradicts) information or
study results already in the public domain.

9.   INFRINGEMENT

     9.1  THIRD PARTY INFRINGEMENT.  If Inventor learns of facts that it
concludes may constitute an infringement of any of the Technology or the
Marks by any third party, Inventor shall promptly notify Amerimmune in
writing, setting forth such facts and the basis for its conclusion, and
shall include with such notice any other reasonably available evidence in
support thereof.

          (a) SUBSTANTIAL INFRINGEMENTS.  Amerimmune shall take appropriate
action at Amerimmune's expense against "Substantial Infringements" of the
Technology or the Marks (including without limitation filing a lawsuit or
arbitration against such third party infringer, if necessary).  For
purposes hereof, a "Substantial Infringement" shall be an infringement of
Technology or Marks (i) where failure by Amerimmune to take appropriate
action against such infringement would result in partial or total loss or
abandonment of rights to the infringed Technology and/or Marks, or (ii) if
the infringement has resulted in more than a 25% reduction in sales of
Licenced Products in any country after introduction into the market in such
country of the infringing product.  Unless Inventor agrees otherwise in
writing, Amerimmune's failure to commence appropriate action against a
Substantial Infringement within thirty (30) days after learning or
receiving written notice of such infringement shall result in the
termination of the License in such country with respect to the Marks (if
one of the Marks is the subject of such Substantial Infringement) or the
infringed Technology.

          (b) OTHER INFRINGEMENTS.  Amerimmune shall have the right, but
not the obligation, at Amerimmune's expense to take such action against
infringements other than Substantial Infringements as Amerimmune deems
appropriate.  If Amerimmune declines to take action (i.e., send demand
letter, file lawsuit) against an infringer within thirty (30) days of
receipt of notice thereof from Inventor, Inventor shall have the right to
take action against such infringer upon giving Amerimmune at least fifteen
(15) days prior written notice.  Amerimmune shall have the right to
participate in such

                                    7
<PAGE>
action, at Amerimmune's expense.  Inventor shall not settle any action
against a third party infringer of the Technology or the Marks without
Amerimmune's prior written consent, which consent shall not be unreasonably
withheld.

          (c) RECOVERY.  Amerimmune shall be entitled to any monetary
award, judgment or settlement resulting from action brought or taken by
Amerimmune against a third party infringer.  Inventor shall be entitled to
any monetary award, judgment or settlement resulting from action brought or
taken by Inventor against a third party infringer.  Any monetary award,
judgment or settlement resulting from action brought or taken jointly by
Amerimmune and Inventor shall be divided between Amerimmune and Inventor
PARI PASSU based on each party's financial contribution towards such result.

     9.2  NOMINAL PLAINTIFF.  If any infringement action, suit or
proceeding is brought hereunder by Amerimmune to enforce any rights in the
Technology or the Marks, Inventor shall upon the request and at the expense
of Amerimmune, cooperate with Amerimmune and be named, joined and
participate therein as a nominal plaintiff.

10.  INDEMNIFICATION

     10.1 INVENTOR INDEMNIFICATION.  Inventor shall indemnify, hold
harmless and defend Amerimmune and its officers, directors, employees,
representatives and agents, from and against any and all claims, demands,
lawsuits, actions, proceedings, liabilities, losses, damages, fees, costs
and expenses (including without limitation attorneys' fees and costs of
investigation and experts) resulting from or arising out of (i) any breach
by Inventor of this Agreement, including without limitation any breach of
the representations, warranties and covenants of Inventor hereunder, (ii)
any claim by 3R or any other party that this Agreement represents an
interference with a contractual relationship or otherwise violates such
party's rights, or (iii) any claim that Amerimmune's exploitation of any
rights in the Technology and the Marks herein licensed infringes or
violates any patent, copyright, trademark or other right of any third party
unless any such infringement or violation is due to actions or inactions by
Amerimmune other than by reason of Amerimmune's exercise of its rights
licensed pursuant to this Agreement; but Amerimmune shall not be entitled
to indemnification hereunder for infringement exclusively resulting from
Amerimmune's improvements to the Technology.

     10.2 AMERIMMUNE INDEMNIFICATION.  Amerimmune shall indemnify, hold
harmless and defend Inventor and its officers, directors, employees,
representatives and agents, from and against any and all claims, demands,
lawsuits, actions, proceedings, liabilities, losses, damages, fees, costs
and expenses (including without limitation attorneys' fees and costs of
investigation and experts) resulting from or arising out of (i) any breach
by Amerimmune of this Agreement, including without limitation any breach of
the representations, warranties and covenants of Amerimmune hereunder, and
(ii) the use of the Licensed Products (including without limitations any
product liability claims) and/or the development, manufacture, marketing,
distribution and/or sale by Amerimmune of the Licensed Products (except for
infringement claims covered by Section 10.1(iii) above).  In addition,
Amerimmune shall require any sublicensee to agree to indemnify Inventor
from and against all product liability claims by persons purchasing
Licensed Products from such sublicensee and/or its agents or distributors.

13.  DISPUTE RESOLUTION BY REFEREE

     Amerimmune and Inventor agree to waive the right to a jury trial and
to submit any disagreement or controversy arising under or relating to this
Agreement or the subject matter hereof for resolution by a trial on Order
of Reference.  Such trial shall be conducted by a retired judge or justice
having expertise in commercial disputes and who is acceptable to both
parties.  The retired judge or justice shall be appointed pursuant to the
provisions of California Code of Civil Procedure Section 638(1) or any
amendment, addition or successor section thereto.  If the parties are unable
to agree upon a retired judge or justice panel to act as referee, then upon
petition by either party to the presiding judge of the Superior Court of the
State of California for the County of Los Angeles, Central District (or such
other judge as the presiding judge may designate for such purpose), such
judge shall in his or her sole discretion select one retired judge or
justice who shall serve as the referee.  Such referee shall hear the
dispute or controversy until the final determination thereof pursuant to
Article VI, Section 21 of the California Constitution, Section 638 ET SEQ.
of the California Code of Civil Procedure, and Rule 244.1(a) of the
California Rules of Court.  The referee shall conduct such reference
proceeding, including making orders relating to discovery to take place in
connection therewith, so that the period of time from such referee's
appointment until the reference proceeding is concluded is not longer than
six (6) months (such period is directory only, and a failure to conclude
such proceeding within such period shall not result in a loss of
jurisdiction by the referee).  The referee's award shall be in writing, and
shall include a statement of decision, in accordance with Section 632 of
the California Code of Civil Procedure.  The parties shall pay in advance,
to the referee, the estimated reasonable fees and costs of the reference as
may be specified in advance by the referee.  The parties shall share
equally, by paying their proportionate amount, the fees and costs of the
reference.  The parties intend this general reference agreement to be
specifically enforceable.

14.  GOVERNING LAW

     This Agreement and the legal relations between the parties shall be
governed by and construed in accordance with the laws of the State of
California, except where such are governed exclusively by federal law.

15.  RELATIONSHIP OF PARTIES

     Each party shall conduct all business in its own name as an

                                EXHIBIT D

                   ADDITIONAL COVENANTS OF AMERIMMUNE


1.  As promptly as reasonably possible following satisfaction of the
License Condition, Amerimmune shall: (i) pay to Inventor any payments owed
to Inventor by Amerimmune under the terms of any Agreements existing as of
the Effective Date between (A) Amerimmune and Inventor or (B) Amerimmune
and 3R, that have been refused by Inventor, but in no event shall the
foregoing be interpreted to require Amerimmune to make any double payment
of any amount owed by Amerimmune; and (ii) use commercially reasonable
efforts (which shall include, without limitation, filing either an
arbitration or a lawsuit to the extent that a claim can be made in good
faith) to cancel the shares of stock of Amerimmune and/or API owned by 3R,
its shareholders, principals, officers, directors or affiliates.

2.  If Inventor acquires shares of stock of Amerimmune and/or API from 3R
or its shareholders, principals, officers, directors or affiliates, and
delivers such shares to Amerimmune pursuant to Section 4 of the Agreement,
Amerimmune shall pay to Inventor the amount of the incremental cost and
expense incurred in acquiring such shares from 3R promptly after Inventor
delivers to Amerimmune evidence reasonably satisfactory to Amerimmune of
the amount of Inventor's incremental cost and expense.  If, in an action or
arbitration brought by Inventor to satisfy the License Condition, shares of
stock of API owned by Inventor are ordered to be and are canceled, then, as
additional consideration for the License, API shall issue to Inventor a
number of shares of the same class of stock of API equal to the number of
shares so canceled.

3.  If the License Condition is satisfied, Amerimmune agrees not to file an
action or arbitration against Inventor seeking return or cancellation of
the shares of stock of Amerimmune and/or API owned by Inventor as of the
Effective Date based on a claim of failure or lack of consideration for
such shares.

4.  If the License Condition is satisfied, Amerimmune agrees not to employ
or enter into any consulting contract with 3R and/or any persons or
entities who as of the Effective Date are shareholders, principals,
officers, directors or affiliates of 3R.

                     EXCEPTIONS TO SECTION 8.2(viii)

Known to us as of February 13, 2000:

Abbott Laboratories of Abbott Park, Ill., a major pharmaceutical company,
has registered the Internet domain name CYTOLIN.COM, according to
information we received from Dr. Strickland the evening of 2/13/00.  It is
not clear why they did so since our trademark would presumably preclude
them from using that trade name on a product.  It is not clear whether this
registration would be an infringement as opposed to an unfair business
practice since the Marks are protected as a description of products.  Of
course, if they don't use the domain name actively, then there is no damage
being as how we have both agreed not to use it.

A company in Florida incorporated under the name Cytodyne Technologies and
has been advertising a nutraceutical weight loss product.  This has caused
confusion in that doctors have asked us if we have entered that field.  Mr.
McCann sent a cease and desist letter on behalf of Amerimmune with no
apparent effect.  Mr. Judson had gone so far as to prepare a complaint but
that was sabotaged by Roy Azarnoff.

                                EXHIBIT F


1.   SPECIAL QUALIFICATIONS FOR A PATENT ATTORNEY USED TO PROSECUTE OR
     DEFEND ALLEN'S PATENTS.

     (a)  Should have successfully prosecuted at least one patent on a
treatment method, preferably more.

     (b)  Should have successfully prosecuted at least one patent,
preferably more, where novelty is a challenge due to the fact that the
invention arises from a better understanding of information in the prior
art and not from new information.

     (c)  After conferring with Mr. Allen should understand the distinction
between an infection, an infectious disease in the sense of Koch, and a
noninfectious disease with an infectious agent, as may be necessary to
argue for novelty.

     (d)  After conferring with Mr. Allen should understand how the laws of
nature can be used predictively by scientists, as may be necessary to argue
for utility.

     (e)  Should be able and willing to advise Amerimmune of how public or
discoverable statements made by Amerimmune, or unchallenged public
statements made by others, that incorrectly characterize the Technology
could lay a foundation for a challenge to any patent licensed under this
Agreement, including but without limitation, by estoppel.

2.   SPECIAL QUALIFICATIONS FOR A PATENT ATTORNEY USED TO ENFORCE AND
     PREVENT INFRINGEMENTS AGAINST ALLEN'S PATENTS.

     Should have extensive knowledge of the statutory and case law on
contributory infringement, the staple exception, and the reasons why a
pharmaceutical product cannot be a staple.

3.   ACKNOWLEDGMENT.

     Inventor acknowledges and agrees that Rod S. Berman, Esq. and David J.
Meyer, Esq., of Jeffer Mangels Butler & Marmaro LLP satisfy all of the
qualifications set forth in this Exhibit F.

                     PRIOR CONFIDENTIAL INFORMATION


     The term "Prior Confidential Information" refers to all data, reports,
drawings, tapes, formulae, interpretations, records, trade secrets,
documents, information regarding products, processes, research and
development, apparatus and application methods that are not and have not

Amerimmune has a nondisclosure obligation, and including all Consultant
Innovations (as defined below).  Additionally, Prior Confidential
Information shall include any and all reports to 3R made by Allen in the
course of performance of that certain Consulting Agreement dated August 1,

reports, models and samples), in any manner pertinent or related to,
resulting from or useful in or to the Technology and all products that
embody or make use of all or any part of the Technology that were or are
conceived (whether or not reduced to practice) or first reduced to practice
by Inventor whether solely or jointly with others, during the term of the
3R Consulting Agreement or as a result of knowledge acquired while

     Inventor:

*    shall hold the Prior Confidential Information in confidence;

*    shall take or cause to be taken all reasonable precautions to prevent
     the disclosure or communication of Prior Confidential Information to
     third parties;

<PAGE>
*    agrees that each reproduction, duplication, or copy of any portion of
     Prior Confidential Information shall be deemed Prior Confidential
     Information for all purposes hereunder.

     Amerimmune agrees Inventor may publish papers in peer review,
scientific and technical journals; provided that Inventor agrees (i) no
such paper will include Prior Confidential Information, (ii) Inventor will
deliver a final copy of the proposed paper to Amerimmune for its approval
no less than 30 days prior to the date he plans to deliver the paper to the
journal publisher, (iii) if Amerimmune advises Inventor that in its
reasonable judgment the paper contains, or could lead to the discovery of,
Prior Confidential Information, Inventor will delete such Confidential
Information or the means of discovering such Information, (iv) if Inventor
or the journal publisher propose to make any change to the paper previously
submitted to Amerimmune, such proposed change will be submitted to
Amerimmune for its approval before it is made and not less than 5 business
days prior to the paper being released to the printer for final printing,
and (v) Inventor will only permit a paper approved by Amerimmune to be
published.  Amerimmune agrees that should it publish any articles
describing the contributions of Allen under this Agreement, it will
acknowledge Allen's contribution to such results.
