Item 5.   Other Events.

On January 20, 2000, the Company reached a settlement on its pending arbitration
with Patrick T. Prendergast ("Prendergast"), Colthurst Limited ("Colthurst") and
Edenland, Inc ("Edenland"). The Settlement and Mutual Release Agreement
completely disposes of all of the matters that were at issue in the pending
arbitration. In addition, the parties entered into two new technology
agreements, the Technology Assignment Agreement and the Sponsored Research and
License Agreement.

The Technology Assignment Agreement replaces the License Agreement dated May 18,
1994 among the Company, Prendergast and Colthurst (the "Colthurst Agreement").
Pursuant to the Technology Assignment Agreement, Prendergast and Colthurst
assigned to the Company ownership of all patents, patent applications and
current or future improvements of the technology under the Colthurst Agreement,
including HE2000, the Company's lead clinical compound. The annual license fee
of $500,000 and the royalty obligations under the Colthurst Agreement have been
eliminated. In consideration for the foregoing, Hollis-Eden agreed to issue to
Colthurst 660,000 shares of Common Stock and a warrant to purchase an aggregate
of 400,000 shares of Common Stock at $25 per share. Only 132,000 of such shares
of Common Stock will be issued now, with the remaining 528,000 shares to be
issued over the next four years conditioned on continued compliance with the
agreement. In addition, all of the shares under the warrant will vest over the
next four years conditioned on continued compliance with the agreement.

The Sponsored Research and License Agreement replaces both the License Agreement
and the Research, Development and Option Agreement, each dated August 25, 1994
among the Company, Prendergast and Edenland. Pursuant to the Sponsored Research
and License Agreement, Edenland exclusively licensed to the Company a number of
compounds, together with all related patents and patent applications, and the
Company agreed to fund additional pre-clinical research projects conducted by
Edenland. The Company will also have exclusive license rights to all results of
such research and will have royalty obligations to Edenland on sales of new
products, if any, resulting from such research.

As a result of the above settlement, the Company will take a one-time charge to
research and development expenses of approximately $12.7 million during the
first quarter of 2000.

FOR IMMEDIATE RELEASE
- ---------------------


                HOLLIS-EDEN PHARMACEUTICALS AND EDENLAND, INC.
                  ANNOUNCE SETTLEMENT OF ARBITRATION MATTERS


SAN DIEGO, CA - January 21, 2000 - Hollis-Eden Pharmaceuticals, Inc. (NASDAQ:
HEPH) today announced that it has reached a settlement on pending arbitration
issues between the Company and Patrick T. Prendergast, Chairman of Colthurst
Ltd. and Edenland, Inc. The settlement includes the transfer of technology to
Hollis-Eden for equity in the Company, and the funding by Hollis Eden of
additional pre-clinical research to be conducted by Edenland.

The parties have replaced the original Colthurst license agreement with a new
agreement in which all patents, patent applications, and current or future
improvements of the Colthurst technology, including HE2000, Hollis-Eden's lead
clinical compound, will be irrevocably assigned to Hollis-Eden on a royalty-free
basis in exchange for equity in Hollis-Eden that will vest over time.

Additionally, the parties have entered into a sponsored research agreement,
replacing both the pre-existing Edenland license agreement and research and
development agreement. Pursuant to the new agreement, Edenland will immediately
license to Hollis-Eden a number of compounds, together with related patents and
patent applications, and Hollis-Eden will fund additional pre-clinical research
projects conducted by Edenland, Inc. Hollis-Eden will also have the license
rights to all results of this research and the agreement provides for a royalty
interest back to Edenland on sales of new products resulting from this
agreement.

Commenting on the settlement, Richard Hollis, Chairman and CEO of Hollis-Eden
stated, "We are very pleased to have quickly settled this matter in an amicable
fashion. We believe the restructured agreements will benefit both parties and
align our interests toward one common vision of commercializing drugs to benefit
patients. We are committed to rewarding our shareholders for their investment in
Hollis-Eden as well as their belief in our scientific endeavors and ultimately
in our ability to build an enterprise that adds value to healthcare around the
world. We look forward to working with Edenland and Patrick T. Prendergast on
new discovery programs."

"We are pleased to have arrived at today's settlement," said Patrick
Prendergast. "Under our new research arrangement I am confident we at Edenland
can bring valuable new drug candidates to the Hollis-Eden pipeline and add to
shareholder value. Richard Hollis has always shared my vision of developing
novel medicines for unmet worldwide medical needs. His commitment and loyalty to
our drug discoveries and his incredible drive to build a worldclass
pharmaceutical company is now beginning to unfold. Hollis-Eden continues to
bring together an expert team of scientists and healthcare executives that share
our mutual vision. On behalf of Colthurst, I'm impressed with the extent of the
analytical testing and the valuable results Hollis-Eden reported from their
clinical trials with HE2000. We feel these new agreements absolutely align our
goals, and we will do everything we can to reward Hollis-Eden shareholders for
the confidence they have placed in us."

Hollis-Eden Pharmaceuticals, Inc. is a development-stage pharmaceutical company
engaged in the development of products for the treatment of infectious diseases
and immune system disorders. The company is currently testing its lead drug
candidate, HE2000, in HIV/AIDS patients both in South Africa and the United
States. HE2000 appears to operate through a novel mechanism that targets the
host cell and may alter the immune system in HIV-positive patients rather than
interfacing directly with the virus. For more information regarding Hollis-Eden,

of any nature whatsoever, arising from or regarding the interpretation,
performance, enforcement or breach of this Agreement, the Technology Assignment
Agreement, the Sponsored Research and License Agreement or the Common Stock and

Association ("AAA") in San Diego, under the then existing AAA commercial
arbitration rules.  All costs of arbitration, including reasonable attorneys'

this provision had never been contained herein, consistent with the general
intent of the Parties insofar as possible.

  7.1     Notices.  Notices, approvals, and consents required or permitted under
this Agreement shall be in writing and shall be sent by hand or by certified
mail, postage prepaid, to such addresses as the parties may hereafter specify;
or by facsimile with electronic confirmation of receipt.

  7.2     No Waiver.  No waiver of any right under this Agreement shall be
deemed effective unless contained in a writing signed by the party charged with
such waiver. Failure by either party to exercise any of its rights hereunder
shall not constitute or be deemed a waiver or forfeiture of such rights.

  7.3     Entire Agreement.  This Agreement, including Attachments A and B
hereto, sets forth the entire understanding of the parties with respect to the
subject matter herein and supersedes all prior agreements, whether oral or
written, between them.  This Agreement may not be modified after its execution
except by a writing signed by authorized representatives of the parties hereto.

  7.4     Draftsmanship.  This Agreement and the wording contained herein have
been arrived at by mutual negotiations of the parties, and no provision hereof
shall be interpreted or construed against one party in favor of another party
merely by reason of draftsmanship.

<PAGE>

without materially altering the intention of the parties, it shall be stricken
and the remainder of this Agreement shall remain in full force and effect.

  7.7     Governing Law.  This Agreement shall be governed by and construed in
accordance with the laws of the State of California, without reference to its
conflicts of law provisions, as though it were written, executed and fully

Agreement, the parties shall refer such dispute to the Chief Executive Officer
of Hollis-Eden and Prendergast for attempted resolution by good faith
negotiations within thirty (30) days after such referral is made.  In the event
such officers are unable to resolve such dispute within such thirty (30) day
period, the parties may invoke the provisions of Sections 7.9 and 7.10 below.

  7.9     Remedies of the Company.  Colthurst and Prendergast acknowledge that
irreparable damage would result to Hollis-Eden if they breach any provision of
this Agreement, and the Company would not have an adequate remedy at law for
such a breach or threatened breach.  In the event of such a breach or threatened
breach, Colthurst and Prendergast agree that Hollis-Eden may, notwithstanding
anything to the contrary herein contained, and in addition to the other remedies
which may be available to it, seek to enjoin them, together with all those
persons associated with them, from the breach or threatened breach of such
covenants, in a court of competent jurisdiction.  Colthurst, Prendergast and
Hollis-Eden agree to the jurisdiction and venue in the federal and state courts
located in San Diego, California.

  7.10    Arbitration.  To ensure rapid and economical resolution of any
disputes which may arise under this Agreement, the parties agree that any and
all disputes or controversies of any nature whatsoever, arising from or
regarding the interpretation, performance, enforcement or breach of this
Agreement shall be resolved by confidential, final and binding arbitration
(rather than trial by jury or court or resolution in some other forum) to the
fullest extent permitted by law. Any arbitration proceeding pursuant to this
Agreement shall be conducted by the American Arbitration Association ("AAA") in
San Diego, under the then existing AAA commercial arbitration rules. If for any
reason all or part of this arbitration provision is held to be invalid, illegal,
or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not effect
any other portion of this arbitration provision or any other jurisdiction, but
this provision will be reformed, construed and enforced in such jurisdiction as
if such invalid, illegal or unenforceable part or parts of this provision had
never been contained herein, consistent with the general intent of the Parties
insofar as possible.

instrument (evidencing a Purchaser debt or otherwise) to which the Purchaser is
a party or by which any property or asset of the Purchaser is bound or affected,
or (iii) result in a violation of any law, rule, regulation, order, judgment,
injunction, decree or other restriction of any court or government authority to
which the Purchaser is subject (including federal and state securities laws and
regulations), or by which any property or asset of the Purchaser is bound or
affected, except in the case of each clauses (ii)  and (iii), as could not,
individually or in the aggregate, have or result in a material adverse effect on
the Purchaser.

  6.3     Rule 144.  Purchaser acknowledges and agrees that the Securities
acquired by Purchaser hereunder must be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such
registration is available.  Purchaser has been advised or is aware of the
provisions of Rule 144 promulgated under the Securities Act, which permits
limited resale of securities subject to the satisfaction of certain conditions,
including, among other things:  the availability of certain current public
information about the Company, the resale occurring not less than one year after
a party has purchased and paid for the security to be sold, the sale being made
through an unsolicited "broker's transaction" or in transactions directly with a
market maker (as said term is defined under the Securities Exchange Act of 1934,
as amended

                                       5.
<PAGE>

(the "Exchange Act")) and the number of shares being sold during any three-month
period not exceeding specified limitations.

  6.4     Covenants.  The Purchaser hereby covenants with the Company as
follows:  (i) prior to the effective date of the Registration Statement
referenced in Section 8.1(a) below (the "Effective Date"), the Purchaser shall
not transfer any Securities except in compliance with the Securities Act and the
rules and regulations promulgated thereunder, and any transferee of Securities
prior to the Effective Date shall agree in advance in a writing acceptable to
the Company to be subject to all of the provisions of this Agreement with
respect to the Securities; and (ii) commencing as of the Effective Date, the
Purchaser shall not make any sale of the Securities, if any, without effectively
causing the prospectus delivery requirement under the Securities Act to be
satisfied, and the Purchaser acknowledges and agrees that on and after the
Effective Date, such Securities are not transferable on the books of the Company
unless the certificate submitted to the transfer agent evidencing the Securities
is accompanied by a separate purchaser's certificate:  (1) in the form of
Exhibit C hereto, (2) executed by the Purchaser or by an officer of, or other
authorized person designated by, the Purchaser, and (3) to the effect that (A)
the Securities have been sold in accordance with the Registration Statement and
(B) the requirement of delivering a current prospectus has been satisfied.  The
Purchaser further covenants to promptly notify the Company of the sale or
transfer of any of its Securities.

7.   SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.  Notwithstanding
any investigation made by any party to this Agreement, all covenants,
agreements, representations and warranties made by the Company and the Purchaser
herein and in the certificates for the Securities delivered pursuant hereto
shall survive the execution of this Agreement and the delivery to the Purchaser
of the Securities being purchased.

8.   REGISTRATION OF THE COMMON STOCK; COMPLIANCE WITH THE SECURITIES ACT.

  8.1     Registration Procedures and Expenses.  The Company shall:

     (a) within 90 days following each Closing, prepare and file with the
Commission a registration statement on Form S-3 (each a "Registration
Statement") in order to register with the Commission the sale of the Warrant
Shares and the Shares issued in such Closing, as applicable (collectively, the
"Registrable Securities"), by the Purchaser from time to time through
underwriters, agents or otherwise, in negotiated or market transactions or
through the automated quotation system of Nasdaq or the facilities of any
national securities exchange on which the Company's Common Stock is then traded
or in privately negotiated transactions or pursuant to such other method or
methods of distribution as Purchaser may require.  It shall be a condition
precedent to the obligations of the Company to take any action pursuant to this
Section 8.1 that the Purchaser shall furnish to the Company such information
regarding itself, the Registrable Securities to be sold by Purchaser, and the
intended method of disposition of such securities as shall be required to effect
the registration of the Registrable Securities.  Notwithstanding the foregoing,
the Company shall not be required to file or effect a registration pursuant to
this Section 8.1 if and for so long as any condition specified in Section 8.1(c)
shall exist and the Company shall have notified the Purchaser's thereof in
accordance with such section;

                                       6.
<PAGE>

     (b) use reasonable efforts, subject to the receipt of necessary information
from the Purchaser, to cause each Registration Statement to become effective as
soon as commercially practicable following the filing thereof with the
Commission;

     (c) prepare and file with the Commission such amendments and supplements to
each Registration Statement and the prospectus used in connection therewith and
take such other actions as may be necessary to keep such Registration Statement
continually effective and not misleading until the earliest of (A) the first
anniversary date of the applicable Closing, or (B) such date as all of the
Registrable Securities registered under such Registration Statement held by the
Purchaser have been resold.  Notwithstanding the foregoing, Purchaser
acknowledges that there may occasionally be times when the Company, in the good
faith judgment of its Chief Executive Officer or its Board of Directors,
determines it must suspend Purchaser's ability to sell Shares or Warrant Shares
pursuant to a Registration Statement until such time as an amendment to such
Registration Statement has been filed by the Company and declared effective by
the Commission, or until such time as the Company has filed an appropriate
report with the Commission pursuant to the Securities Exchange Act of 1934, as
amended (a "Suspension").  The Purchaser agrees that, upon receipt of any notice
from the Company of a Suspension, the Purchaser will not sell any Shares or
Warrant Shares pursuant to the Registration Statement until the Purchaser is
advised in writing by the Company that the use of the applicable prospectus may
be resumed; provided, that such limitation on selling shares of Common Stock
also applies to the executive officers and directors of the Company;

     (d) furnish to the Purchaser with respect to the Registrable Securities
registered under a Registration Statement such number of copies of prospectuses
and preliminary prospectuses in conformity with the requirements of the
Securities Act, in order to facilitate the public sale or other disposition of
all or any of the Registrable Securities by the Purchaser; provided, however,
that the obligation of the Company to deliver copies of prospectuses or
preliminary prospectuses to the Purchaser shall be subject to the receipt by the
Company of reasonable assurances from the Purchaser that the Purchaser will
comply with the applicable provisions of the Securities Act and of such other
securities or blue sky laws as may be applicable in connection with any use of
such prospectuses or preliminary prospectuses;

     (e) file documents required of the Company for normal blue sky clearance in
states specified in writing by the Purchaser; provided, however, that the
Company shall not be required to qualify to do business or consent to service of
process in any jurisdiction in which it is not now so qualified or has not so
consented; and

     (f) bear all expenses incurred by the Company in connection with the
procedures in paragraphs (a) through (e) of this Section 8.1 and the
registration of the Registrable Securities pursuant to each Registration
Statement.

  8.2     Notification of Changes.  The Purchaser agrees that it will promptly
notify the Company of any changes in the material information set forth in each
Registration Statement regarding the Purchaser or its plan of distribution with
respect to the Registrable Securities, as applicable.

                                       7.

  8.3     Indemnification.

     (a) the term "Selling Stockholder" shall mean the Purchaser and, if the
Purchaser is an institution, the Purchaser's directors or trustees, officers and
employees and each person who controls the Purchaser within the meaning of the
Securities Act;

     (b) the term "Registration Statement" shall include any final prospectus,
exhibit, supplement or amendment included in or relating to the Registration
Statements referred to in Section 8.1; and

     (c) the term "untrue statement" shall include any untrue statement or
alleged untrue statement, or any omission or alleged omission, to state in the
Registration Statement a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

     The Company agrees to indemnify and hold harmless each Selling Stockholder
from and against any losses, claims, damages or liabilities to which such
Selling Stockholder may become subject (under the Securities Act or otherwise)
insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon, any untrue
statement contained in a Registration Statement on the Effective Date thereof,
or arise out of any failure by the Company to fulfill any undertaking herein or
included in a Registration Statement, and the Company will reimburse such
Selling Stockholder for any reasonable legal or other expenses reasonably
incurred in investigating, defending or preparing to defend any such action,
proceeding or claim; provided, however, that the Company shall not be liable in
any such case to the extent that such loss, claim, damage or liability arises
out of, or is based upon, an untrue statement made in such Registration
Statement in reliance upon and in conformity with written information furnished
to the Company by or on behalf of such Selling Stockholder specifically for use
in preparation of a Registration Statement, or the failure of such Selling
Stockholder to comply with the covenants and agreements contained in Section 5
or 8.2 hereof respecting sale of the Registrable Securities or any statement or
omission in any prospectus that is corrected in any subsequent prospectus that
was delivered to the Purchaser prior to the pertinent sale or sales by the
Purchaser.

     The Purchaser agrees to indemnify and hold harmless the Company (and each
person, if any, who controls the Company within the meaning of Section 15 of the
Securities Act, each officer of the Company who signs a Registration Statement
and each director of the Company) from and against any losses, claims, damages
or liabilities to which the Company (or any such officer, director or
controlling person) may become subject (under the Securities Act or otherwise),
insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon, any failure to
comply with the covenants and agreements contained in Section 6 or 8.2 hereof
respecting sale of the Registrable Securities, or any untrue statement contained
in a Registration Statement on the Effective Date if such untrue statement was
made in reliance upon and in conformity with written information furnished by or
on behalf of the Purchaser specifically for use in preparation of a Registration
Statement, and the Purchaser will reimburse the Company (or such officer,
director or controlling person, as the case may be) for any legal or other
expenses reasonably incurred in investigating, defending or preparing to defend
any such action, proceeding or claim.  In no event shall the liability of the

                                       8.
<PAGE>

Purchaser hereunder be greater in amount than the dollar amount of the gross
proceeds received by the Purchaser upon the sale of Registrable Securities
giving rise to such indemnification obligation.

     Promptly after receipt by any indemnified person of a notice of a claim or
the beginning of any action in respect of which indemnity is to be sought
against an indemnifying person pursuant to this Section 8.3, such indemnified
person shall notify the indemnifying person in writing of such claim or of the
commencement of such action, and, subject to the provisions hereinafter stated,
in case any such action shall be brought against an indemnified person and such
indemnifying person shall have been notified thereof, such indemnifying person
shall be entitled to participate therein, and, to the extent it shall wish, to
assume the defense thereof, with counsel reasonably satisfactory to such
indemnified person.  After notice from the indemnifying person to such
indemnified person of its election to assume the defense thereof, such
indemnifying person shall not be liable to such indemnified person for any legal
expenses subsequently incurred by such indemnified person in connection with the
defense thereof; provided, however, that if there exists or shall exist a
conflict of interest that would make it inappropriate, in the opinion of counsel
to the indemnified person, for the same counsel to represent both the
indemnified person and such indemnifying person or any affiliate or associate
thereof, the indemnified person shall be entitled to retain its own counsel at
the expense of such indemnifying person; provided, however, that no indemnifying
person shall be responsible for the fees and expenses of more than one separate
counsel for all indemnified parties.

     If the indemnification provided for in this Section 8.3 is held by a court
of competent jurisdiction to be unavailable to an indemnified party with respect
to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the extent permitted by applicable law contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the act or omission that resulted in such loss, claim, damage
or liability, as well as any other relevant equitable considerations.  The
relative fault of the indemnifying party and of the indemnified party shall be
determined by a court of law by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the indemnifying party or by
the indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission;
provided, however, that (i) no person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any party who was not guilty of such fraudulent
misrepresentation, and (ii) contribution (together with any indemnification or
other obligations under this Agreement) by any seller of Shares or the Warrant
Shares shall be limited in amount to the amount of gross proceeds received by
such seller from the sale of such Shares or the Warrant Shares.

     The obligations of the Company and Purchaser under this Section 8.3 shall
survive completion of any offering of Registrable Securities in a Registration
Statement and the termination of this Agreement.  No indemnifying party, in the
defense of any such claim or litigation, shall, except with the consent of each
indemnified party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof

                                       9.
<PAGE>

the giving by the claimant or plaintiff to such indemnified party of a release
from all liability in respect to such claim or litigation.

  8.4     Termination of Conditions and Obligations.  Notwithstanding anything
stated herein to the contrary, the conditions precedent imposed by Section 6 or
this Section 8 upon the transferability of the Shares or the Warrant Shares
shall cease and terminate as to any particular number of the Shares or Warrant
Shares, when such Shares or Warrant Shares shall have been effectively
registered under the Securities Act and sold or otherwise disposed of in
accordance with the intended method of disposition set forth in the Registration
Statement covering such or at such time as an opinion of counsel satisfactory to
the Company shall have been rendered to the effect that such conditions are not
necessary in order to comply with the Securities Act.

     Purchaser's right to have the Company register the Registrable Securities
pursuant to this Agreement shall not be assignable by Purchaser to any
transferee of all or any portion of the Registrable Securities, unless such
transferee (i) is an affiliate of the Purchaser and (ii) prior to such transfer
taking place, agrees with the Company in writing to be bound by the terms of
this Agreement.

  8.5     Adjustments to Stock.  If, from time to time, before the fourth and
final Subsequent Closing, there is any change affecting the Company's
outstanding Common Stock as a class that is effected without the receipt of
consideration by the Company (through merger, consolidation, reorganization,
reincorporation, stock dividend, dividend in property other than cash, stock
split, liquidating, dividend, combination of shares, change in corporation
structure or other transaction not involving the receipt of consideration by the
Company), then in addition to the Shares not yet issued in a Subsequent Closing
(the "Unissued Shares"), the Purchaser shall be entitled to receive (when such
Unissued Shares are issued at the corresponding Subsequent Closing) any and all
new, substituted or additional securities or other property to which Purchaser
would have been entitled to receive by reason of Purchaser's ownership of the
Unissued Shares.  Such additional securities shall be included in the word
"Shares" for purposes of the registration rights contained in Section 8 of this
Agreement.  Conversely, if, from time to time, before the fourth and final
Subsequent Closing, the outstanding shares of Common Stock of the Company are
combined into a smaller number of shares (for example, through a reverse stock
split), the number of Unissued Shares shall be proportionately reduced.

9.   LEGEND.  Each certificate representing Shares or Warrant Shares shall
(unless otherwise permitted by the provisions of the Agreement) be stamped or
otherwise imprinted with a legend substantially similar to the following (in
addition to any legend required under applicable state securities laws or as
provided elsewhere in this Agreement):

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD
     OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL
     REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL OR BASED ON OTHER
     WRITTEN EVIDENCE IN THE FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF
     THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS
     IN COMPLIANCE THEREWITH."

                                      10.
<PAGE>

10.  CHANGE IN CONTROL.  In the event of (a) a sale of substantially all of the
assets of the Company; (b) a merger or consolidation in which the Company is not
the surviving corporation (other than a merger or consolidation in which
shareholders immediately before the merger or consolidation have, immediately
after the merger or consolidation, greater stock voting power); (c) a reverse
merger in which the Company is the surviving corporation but the shares of the
Company's common stock outstanding immediately preceding the merger are
converted by virtue of the merger into other property, whether in the form of
securities, cash or otherwise (other than a reverse merger in which stockholders
immediately before the merger have, immediately after the merger, greater stock
voting power); or (d) any transaction or series of related transactions in which
in excess of 50% of the Company's voting power is transferred, then, so long as
a Triggering Breach has not occurred, immediately prior to the closing or
consummation of any such event, the Company shall issue to the Purchaser any
Shares that have not already been issued to the Purchaser under this Agreement.

11.  NOTICES.  All notices, requests, consents and other communications
hereunder shall be in writing, shall be sent by facsimile or mailed by first
class registered or certified airmail, or nationally recognized overnight

12.  CHANGES.  Neither this Agreement nor any provision hereof may be changed,
waived, discharged, terminated, modified or amended except pursuant to an
instrument in writing signed by the Company and the Purchaser.

13.  HEADINGS.  The headings of the various sections of this Agreement have been
inserted for convenience of reference only and shall not be deemed to be part of
this Agreement.

14.  SEVERABILITY.  In case any provision contained in this Agreement should be
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein shall not in any way
be affected or impaired thereby.

accordance with the laws of the State of California as applied to contracts
entered into and performed entirely in California by California residents,
without regard to conflicts of law principles.

16.  COUNTERPARTS.  This Agreement may be executed in two or more counterparts,
each of which shall constitute an original, but all of which, when taken
together, shall constitute but one instrument.

17.  SUCCESSORS AND ASSIGNS.  Except as otherwise expressly provided herein,
this Agreement and the provisions hereof shall inure to the benefit of, and be
binding upon, the successors, assigns, heirs, executors and administrators of
each of the parties hereto.

18.  FURTHER ACTIONS.  Each party shall do and perform, or cause to be done and
performed, all such further acts and things, and shall execute and deliver all
such other agreements, certificates, instruments and documents, as the other
party may reasonably request in transactions of this nature in order to carry
out the intent and accomplish the purposes of this Agreement and the
consummation of the transactions contemplated hereby.

19.  ENTIRE AGREEMENT.  This Agreement and other documents delivered pursuant
hereto, including the exhibits, constitute the full and entire understanding and
agreement between the parties with regard to the subjects hereof and thereof.

20.  PAYMENT OF FEES AND EXPENSES.  Except as expressly set forth herein, each
of the Company and the Purchaser shall bear its own expenses and legal fees
incurred on its behalf with respect to this Agreement and the transactions

21.  ARBITRATION.  To ensure rapid and economical resolution of any disputes
which may arise under this Agreement, the Purchaser and the Company agree that
any and all disputes or controversies of any nature whatsoever, arising from or
regarding the interpretation, performance, enforcement or breach of this
Agreement, shall be resolved by confidential, final and binding arbitration
(rather than trial by jury or court or resolution in some other forum) to the
fullest extent permitted by law. Any arbitration proceeding pursuant to this
Agreement shall be conducted by the American Arbitration Association ("AAA") in
San Diego, under the then existing AAA commercial arbitration rules. If for any
reason all or part of this arbitration provision is held to be invalid, illegal,
or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not effect
any other portion of this arbitration provision or any other jurisdiction, but
this provision will be reformed, construed and enforced in such jurisdiction as
if such invalid, illegal or unenforceable part or parts of this provision had
never been contained herein, consistent with the general intent of the parties
to this Agreement insofar as possible.  In no event shall the remedy for any
breach hereunder result in the ownership by Prendergast, Colthurst or any of
their affiliates in the Technology or the Patents and Applications (as such
terms are defined in the Assignment Agreement).

value received, is entitled to purchase from Hollis-Eden Pharmaceuticals, Inc.,
a Delaware corporation (the "Company"), having a place of business at 9333
Genesee Avenue, Suite 200, San Diego, California 92121, a maximum of 400,000
fully paid and nonassessable shares of the Company's Common Stock ("Common
Stock") for cash at a price of $25.00 per share (the "Stock Purchase Price") at
any time or from time to time up to and including 5:00 p.m. (Pacific time) on
January 19, 2005 (the "Expiration Date"), upon surrender to the Company at its
principal office (or at such other location as the Company may advise the Holder
in writing) of this Warrant properly endorsed with the Notice of Exercise
attached hereto as Exhibit A (the "Notice of Exercise") duly completed and
signed and, if applicable, upon payment in cash or by check of the aggregate
Stock Purchase Price for the number of shares for which this Warrant is being
exercised determined in accordance with the provisions hereof. The Stock
Purchase Price and the number of shares purchasable hereunder are subject to
adjustment as provided in Section 4 of this Warrant.

     This Warrant is subject to the following terms and conditions:

     1.   EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES.  This Warrant
is exercisable at the option of the holder of record hereof, at any time or from
time to time, up to the Expiration Date for all or any part of the shares of
Common Stock (but not for a fraction of a share) which may be purchased
hereunder that have Vested according to the vesting schedule described in
Section 12 of this Warrant.  The Company agrees that the shares of Common Stock
purchased under this Warrant shall be and are deemed to be issued to the Holder
hereof as the record owner of such shares as of the close of business on the
date on which this Warrant shall have been surrendered, properly endorsed,
together with a completed Notice of Exercise, and payment made for such shares.
Certificates for the shares of Common Stock so purchased, together with any
other securities or property to which the Holder hereof is entitled upon such
exercise, shall be delivered to the Holder hereof by the Company at the
Company's expense within a reasonable time after the rights represented by this
Warrant have been so exercised.  In case of a purchase of less than all the
shares which may be purchased under this Warrant, the Company shall cancel this
Warrant and execute and deliver a new Warrant or Warrants of like tenor for the
balance of the shares purchasable under the Warrant surrendered upon such
purchase to the Holder hereof within a reasonable time.  Each stock certificate
so delivered shall

                                      1.
<PAGE>

be in such denominations of Common Stock as may be requested by the Holder
hereof and shall be registered in the name or names as nominated by such Holder.

     2.   NET EXERCISE.  Notwithstanding any provisions herein to the contrary,
if the fair market value of one share of the Company's common stock is greater
than the Stock Purchase Price (at the date of calculation as set forth below),
in lieu of exercising this Warrant by payment of cash, the Holder may elect to
receive shares equal to the value (as determined below) of this Warrant (or the
portion thereof being canceled) by surrender of this Warrant at the principal
office of the Company together with the properly endorsed Notice of Exercise in
which event the Company shall issue to the Holder a number of shares of Common
Stock computed using the following formula:

     X =  Y (A-B)
          -------
            A

Where   X =     the number of shares of Common Stock to be issued to the Holder

        Y =     the number of shares of Common Stock purchasable under this
                Warrant or, if only a portion of the Warrant is being exercised,
                the portion of this Warrant being canceled (at the date of such
                calculation)

        A =     the fair market value of one share of the Company's common stock
                (at the date of such calculation)

        B =     Stock Purchase Price (as adjusted to the date of such
                calculation)

     For purposes of the above calculation, the fair market value of one share
of common stock shall be determined by the closing price of the Company's common
stock on the Nasdaq National Market (or other exchange on which the Company's
common stock may be trading) on the business day prior to the date of the
exercise of this Warrant.

     3.   SHARES TO BE FULLY PAID; RESERVATION OF SHARES.  The Company covenants
and agrees that all shares of Common Stock which may be issued upon the exercise
of the rights represented by this Warrant will, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable and free from all
preemptive rights of any stockholder and free of all taxes, liens and charges
with respect to the issue thereof.  The Company further covenants and agrees
that, during the period within which the rights represented by this Warrant may
be exercised, the Company will at all times have authorized and reserved, for
the purpose of issue or transfer upon exercise of the subscription rights
evidenced by this Warrant, a sufficient number of shares of authorized but
unissued Common Stock, or other securities and property, when and as required to
provide for the exercise of the rights represented by this Warrant.  The Company
will take all such action as may be necessary to assure that such shares of
Common Stock may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of any domestic securities
exchange upon which the Common Stock may be listed. The Company will not take
any action which would result in any adjustment of the Stock Purchase Price (as
set forth in Section 5 hereof) if the total number of shares of Common Stock
issuable after such action upon exercise of all outstanding options, warrants
and convertible

                                      2.
<PAGE>

securities, together with all shares of Common Stock then outstanding, would
exceed the total number of shares of Common Stock then authorized by the
Company's Certificate of Incorporation.

     4.   ADJUSTMENT OF STOCK PURCHASE PRICE AND NUMBER OF SHARES.  The Stock
Purchase Price and the number of shares purchasable upon the exercise of this
Warrant shall be subject to adjustment from time to time upon the occurrence of
certain events described in this Section 4.  Upon each adjustment of the Stock
Purchase Price, the Holder of this Warrant shall thereafter be entitled to
purchase, at the Stock Purchase Price resulting from such adjustment, the number
of shares obtained by multiplying the Stock Purchase Price in effect immediately
prior to such adjustment by the number of shares purchasable pursuant hereto
immediately prior to such adjustment, and dividing the product thereof by the
Stock Purchase Price resulting from such adjustment.

          4.1  Subdivision or Combination of Stock.  In case the Company shall
at any time subdivide its outstanding shares of Common Stock into a greater
number of shares, the Stock Purchase Price in effect immediately prior to such
subdivision shall be proportionately reduced, and conversely, in case the
outstanding shares of Common Stock of the Company shall be combined into a
smaller number of shares, the Stock Purchase Price in effect immediately prior
to such combination shall be proportionately increased.

          4.2  Dividends in Common Stock, Other Stock, Property,
Reclassification.  If at any time or from time to time the Holders of Common
Stock (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or become entitled to receive,
without payment therefore:

               (a) Common Stock or any shares of stock or other securities which
are at any time directly or indirectly convertible into or exchangeable for
Common Stock, or any rights or options to subscribe for, purchase or otherwise
acquire any of the foregoing by way of dividend or other distribution, or

               (b) Common Stock or additional stock or other securities or
property (including cash) by way of spinoff, split-up, reclassification,
combination of shares or similar corporate rearrangement (other than shares of
Common Stock issued as a stock split or adjustments in respect of which shall be
covered by the terms of Section 4.1 above), then and in each such case, the
Holder hereof shall, upon the exercise of this Warrant, be entitled to receive,
in addition to the number of shares of Common Stock receivable thereupon, and
without payment of any additional consideration therefor, the amount of stock
and other securities and property (including cash in the case referred to in
this clause (b)) which such Holder would hold on the date of such exercise had
he been the holder of record of such Common Stock as of the date on which
holders of Common Stock received or became entitled to receive such shares or
all other additional stock and other securities and property.

          4.3  Reorganization, Reclassification, Consolidation, Merger or Sale.
If any recapitalization, reclassification or reorganization of the capital stock
of the Company, or any consolidation or merger of the Company with another
corporation, or the sale of all or substantially all of its assets or other
transaction shall be effected in such a way that holders of

                                      3.
<PAGE>

Common Stock shall be entitled to receive stock, securities, or other assets or
property (a "Transaction"), then, as a condition of such Transaction, lawful and
adequate provisions shall be made by the Company whereby the Holder hereof shall
thereafter have the right to purchase and receive (in lieu of the shares of the
Common Stock of the Company immediately theretofore purchasable and receivable
upon the exercise of the rights represented hereby) such shares of stock,
securities or other assets or property as may be issued or payable with respect
to or in exchange for a number of outstanding shares of such Common Stock equal
to the number of shares of such stock immediately theretofore purchasable and
receivable upon the exercise of the rights represented hereby; provided,
however, that in the event the fair market value of the stock, securities or
other assets or property (determined in good faith by the Board of Directors of
the Company) issuable or payable with respect to one share of the Common Stock
of the Company immediately theretofore purchasable and receivable upon the
exercise of the rights represented hereby is in excess of the Stock Purchase
Price hereof effective at the time of a merger and securities received in such
reorganization, if any, are publicly traded, then this Warrant shall expire
unless exercised prior to such Transaction. In the event of any Transaction,
appropriate provision shall be made by the Company with respect to the rights
and interests of the Holder of this Warrant to the end that the provisions
hereof (including, without limitation, provisions for adjustments of the Stock
Purchase Price and of the number of shares purchasable and receivable upon the
exercise of this Warrant) shall thereafter be applicable, in relation to any
shares of stock, securities or assets thereafter deliverable upon the exercise
hereof. The Company will not effect any such consolidation, merger or sale
unless, prior to the consummation thereof, the successor corporation (if other
than the Company) resulting from such consolidation or the corporation
purchasing such assets shall assume by written instrument reasonably
satisfactory in form and substance to the Holders of a majority of the warrants
to purchase Common Stock then outstanding, executed and mailed or delivered to
the registered Holder hereof at the last address of such Holder appearing on the
books of the Company, the obligation to deliver to such Holder such shares of
stock, securities or assets as, in accordance with the foregoing provisions,
such Holder may be entitled to purchase.

          4.4  Certain Events.  If any change in the outstanding Common Stock of
the Company or any other event occurs as to which the other provisions of this
Section 4 are not strictly applicable or if strictly applicable would not fairly
protect the purchase rights of the Holder of the Warrant in accordance with such
provisions, then the Board of Directors of the Company shall make an adjustment
in the number and class of shares available under the Warrant, the Stock
Purchase Price or the application of such provisions, so as to protect such
purchase rights as aforesaid.  The adjustment shall be such as will give the
Holder of the Warrant upon exercise for the same aggregate Stock Purchase Price
the total number, class and kind of shares as he would have owned had the
Warrant been exercised prior to the event and had he continued to hold such
shares until after the event requiring adjustment.

          4.5  Notices of Change.

               (a) Within 60 days after any adjustment in the number or class of
shares subject to this Warrant and of the Stock Purchase Price, the Company
shall give written notice thereof to the Holder, setting forth in reasonable
detail and certifying the calculation of such adjustment.

                                      4.
<PAGE>

               (b) The Company shall also give written notice to the Holder at
least 5 business days prior to the date on which a Transaction shall take place.

     5.   ISSUE TAX. The issuance of certificates for shares of Common
Stock upon the exercise of the Warrant shall be made without charge to the
Holder of the Warrant for any issue tax (other than any applicable income taxes
for which the Company may make requisite withholdings) in respect thereof;
provided, however, that the Company shall not be required to pay any tax which
may be payable in respect of any transfer involved in the issuance and delivery
of any certificate in a name other than that of the then Holder of the Warrant
being exercised.

     6.   CLOSING OF BOOKS.  The Company will at no time close its transfer
books against the transfer of any warrant or of any shares of Common Stock
issued or issuable upon the exercise of any warrant in any manner which
interferes with the timely exercise of this Warrant.

     7.   NO VOTING OR DIVIDEND RIGHTS; LIMITATION OF LIABILITY.  Nothing
contained in this Warrant shall be construed as conferring upon the Holder
hereof the right to vote or to consent or to receive notice as a stockholder of
the Company or any other matters or any rights whatsoever as a stockholder of
the Company.  No dividends or interest shall be payable or accrued in respect of
this Warrant or the interest represented hereby or the shares purchasable
hereunder until, and only to the extent that, this Warrant shall have been
exercised.  No provisions hereof, in the absence of affirmative action by the
holder to purchase shares of Common Stock, and no mere enumeration herein of the
rights or privileges of the holder hereof, shall give rise to any liability of
such Holder for the Stock Purchase Price or as a stockholder of the Company,
whether such liability is asserted by the Company or by its creditors.

     8.   WARRANTS NON-TRANSFERABLE.  Neither this Warrant nor any of Holder's
rights hereunder are transferable, in whole or in part, to any third party,
unless such transfer is made to an affiliate or shareholder of Holder with the
Company's prior written consent.  Any attempted assignment or transfer in
violation of the foregoing will be void.

     9.   RIGHTS AND OBLIGATIONS SURVIVE EXERCISE OF WARRANT.  The rights and
obligations of the Company, of the holder of this Warrant and of the holder of
shares of Common Stock issued upon exercise of this Warrant shall survive the
exercise of this Warrant.

     10.  MODIFICATION AND WAIVER.  This Warrant and any provision hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

     11.  REGISTRATION RIGHTS.  The Holder shall have such registration rights
with respect to the Common Stock issuable upon exercise of the Warrant as are
set forth in that certain Common Stock and Warrant Agreement between the Holder
and the Company dated the date hereof, to which a form of this Warrant is
attached.

     12.  VESTING OF WARRANT.  The Warrant shall be considered "Vested"
according to the following schedule:

                                      5.
<PAGE>

          12.1 So long as a Triggering Event (as defined in Section 12.2) has
not occurred, the Warrant shall vest with respect to 25% of the shares of Common
Stock on the first anniversary of the effective date of this Warrant and the
remaining 75% shall vest monthly thereafter ratably over the next 36 months;
provided however, that in the event of a Change in Control (as defined below)
then, so long as a Triggering Event has not occurred, all of the shares of
Common Stock shall immediately vest.

          12.2 For purposes of this Warrant a "Triggering Event" shall mean the
occurrence of any of the following events:  (A) the Purchaser, Patrick T.
Prendergast or Edenland Inc. or any of their employees, agents, directors,
subsidiaries, representatives, affiliates or family members who are stockholders
of the Company (i) fail to support, and vote all of his, her or its shares of
the common stock of the Company in favor of, any management or board of
directors proposals subject to a stockholder vote of the Company; (ii) encourage
any of the Company's stockholders or potential stockholders to (a) vote against
any management or board of directors proposal subject to stockholder vote of the
Company, (b) submit a proposal for stockholder approval not previously approved
in writing by the Company's board of directors, or (c) vote in favor of any
proposal subject to stockholder vote of the Company not supported by the
Company's board of directors; (iii) conduct any further research or development
of any kind relating to the Technology (as defined in the that certain
Technology Assignment Agreement dated the date hereof among Colthurst Limited,
Patrick T. Prendergast and the Company (the "Assignment Agreement"); or (iv)
make any short sale or maintain any short position, or establish or maintain a
"put equivalent position" (within the meaning of Rule 16a-1(h) under the
Securities Exchange Act of 1934, as amended) with respect to the Company's
common stock; or (B) the inaccuracy of any of the representations and warranties
made by Patrick T. Prendergast or Colthurst Limited under Article V of the
Assignment Agreement as of the date of the Assignment Agreement.  The actions
described in clause (A)(ii) of the foregoing sentence shall not constitute a
Triggering Event unless the Company demonstrates to the Purchaser the occurrence
of such actions by a preponderance of the evidence.  The actions described in
clauses (A)(i) and (ii) above shall constitute a Triggering Event only during
such time as Richard B. Hollis is either the Chairman or the Chief Executive
Officer of the Company, unless the reason for the his failure to be either the
Chairman or the Chief Executive Officer is due to his death or disability.  In
the event that a Triggering Event occurs, the Holder acknowledges and agrees
that it will have no further claim to (i) any additional Warrant Shares or (ii)
the Technology or the Patents and Applications (as such terms are defined in the
Assignment Agreement).

          12.3 For purposes of this Warrant a "Change in Control" shall mean (a)
a sale of substantially all of the assets of the Company; (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation in which shareholders immediately before the merger or
consolidation have, immediately after the merger or consolidation, greater stock
voting power); (c) a reverse merger in which the Company is the surviving
corporation but the shares of the Company's common stock outstanding immediately
preceding the merger are converted by virtue of the merger into other property,
whether in the form of securities, cash or otherwise (other than a reverse
merger in which stockholders immediately before the merger have, immediately
after the merger, greater stock voting power); or (d) any transaction or series
of related transactions in which in excess of 50% of the Company's voting power
is transferred.

                                      6.
<PAGE>

     13.  NOTICES.  Any notice, request or other document required or permitted
to be given or delivered to the holder hereof or the Company shall be delivered
or shall be sent by certified mail, postage prepaid, to each such holder at its
address as shown on the books of the Company or to the Company at the address
indicated therefor in the first paragraph of this Warrant or such other address
as either may from time to time provide to the other.

     14.  BINDING EFFECT ON SUCCESSORS.  This Warrant shall be binding upon any
corporation succeeding the Company by merger, consolidation or acquisition of
all or substantially all of the Company's assets.  All of the obligations of the
Company relating to the Common Stock issuable upon the exercise of this Warrant
shall survive the exercise and termination of this Warrant.

     15.  DESCRIPTIVE HEADINGS AND GOVERNING LAW.  The description headings of
the several sections and paragraphs of this Warrant are inserted for convenience
only and do not constitute a part of this Warrant.  This Warrant shall be
construed and enforced in accordance with, and the rights of the parties shall
be governed by, the laws of the State of Delaware.

     16.  LOST WARRANTS.  The Company represents and warrants to the Holder
hereof that upon receipt of evidence reasonably satisfactory to the Company of
the loss, theft, destruction, or mutilation of this Warrant and, in the case of
any such loss, theft or destruction, upon receipt of an indemnity reasonably
satisfactory to the Company, or in the case of any such mutilation upon
surrender and cancellation of such Warrant, the Company, at its expense, will
make and deliver a new Warrant, of like tenor, in lieu of the lost, stolen,
destroyed or mutilated Warrant.

     17.  FRACTIONAL SHARES.  No fractional shares shall be issued upon exercise
of this Warrant.  The Company shall, in lieu of issuing any fractional share,
pay the holder entitled to such fraction a sum in cash equal to such fraction
multiplied by the then effective Stock Purchase Price.

     2.1 CONDUCT OF RESEARCH.

          (a) In consideration of the Research funding provided by Hollis-Eden
under Section 6.1, Prendergast agrees to undertake and perform the Research. The
Research will be conducted and supervised by Prendergast. Prendergast agrees to
use diligent efforts to perform the Research, and all of Prendergast's research
efforts within the fields of medical, biochemical, biological and/or
pharmaceutical research during the Research Term (as that term is defined in
Section 2.2) shall be devoted to the Research. Prendergast agrees that all work
done on the Research and all Research Results will be duly recorded and
evidenced in laboratory notebooks maintained by the persons working on the
Research, which notebooks shall be available for inspection by Hollis-Eden
pursuant to Section 2.3.

          (b) Prendergast shall have the right to employ, at his sole
discretion, other persons and subcontractors to carry out the Research under
Prendergast's supervision, provided that such persons are under an obligation to
assign and transfer to Prendergast any inventions, discoveries, or other
Know-How they may make or develop in the course of performing the Research which
obligation to assign must be sufficient in scope to effectively result in
ownership by Prendergast of all Research Results produced or contributed to by
such other person or subcontractor. Such inventions, discoveries or other
Know-How shall be exclusively licensed to Hollis-Eden pursuant to Article 3.
Hollis-Eden shall provide Prendergast with a form of assignment to be used with
respect to any such assignments from third parties. Prendergast promptly will
provide to Hollis-Eden a copy of any such agreement with such persons.

          (c) The Research shall be limited to discovery and preclinical
research on the Compounds and Know-How set forth in Exhibit C attached hereto
and, with the prior written consent of Hollis-Eden, any other compounds and
Know-How, including such research in any animal or other model or system up to,
and including, primate models, and specifically excluding clinical research in
humans. In addition, the Research shall not involve, and Prendergast covenants
that he shall not conduct, any research or other work on any subject matter
relating to the "Patents and Applications" or the "Technology" as such terms are
defined in the Technology Assignment Agreement.

stage shall be Hollis-Eden's sole right and responsibility and at Hollis-Eden's
sole discretion, subject to the provisions of Article 5. Development
responsibility for each Compound shall shift from Prendergast to Hollis-Eden on
the earlier of (i) the date Hollis-Eden receives copies of all preclinical data
regarding the Compound that Prendergast has generated and intends to generate
under the Research; or (ii) the date Hollis-Eden, at its sole discretion, elects
to begin conducting its own development activities with respect to that
Compound. No later than ninety (90) days after the foregoing shift of
development responsibility for a particular Compound (the "Development Transfer
Date" for such Compound), Prendergast shall discontinue and conduct no further
Research or other work with respect to such Compound or any Related Compound of
such Compound unless such work is expressly requested by Hollis-Eden in writing
to be conducted under the Research.

Product.

          (b) No royalties shall be payable under Section 6.2 on Net Sales
generated from a Product sold after the tenth (10th) anniversary of the
regulatory approval for a particular Product in a particular country, in each
country where the Product is not then covered in whole or in part by any issued
claim in a patent contained in the Research Patents or Patents and Applications.

          (c) In each country where the Product was covered in whole or in part
by any issued patent contained in the Research Patents or Patents and
Applications in such country, no royalties shall be payable under Section 6.2 on
Net Sales generated from a Product sold in such country after the date that all
such issued patents in such country have expired or been held invalid or
unenforceable by a final decision of a court that is no longer appealed or
appealable.

     6.6 PAYMENTS AND REPORTS. All amounts payable to Edenland under this
Agreement shall be paid in U.S. dollars to a bank account specified by Edenland.
The royalty obligation under Section 6.2 shall accrue at the time of sale of the

shall accrue at the time that Hollis-Eden receives payments from its
sublicensees that are subject to such a payment obligation, and such payment
obligations that accrue during a semi-annual period shall be paid within sixty
(60) days after the end of each semi-annual period. Royalty obligations that
accrue during a particular semi-annual period shall be paid within sixty (60)
days after the end of each semi-annual period. Each payment of royalties due
Edenland under Sections 6.2 and 6.3 shall be accompanied by a statement of the
amount of Net Sales during such period, the amount of payments by Hollis-Eden's
sublicensees, and such other information as is necessary to determine the
appropriate amount of such payments by Hollis-Eden.

     6.7 EXCHANGE RATE. The rate of exchange to be used in computing the amount
of currency equivalent in United States dollars due Edenland shall be made at
the period end rate of exchange quoted on the last business day of the royalty
period in the Wall Street Journal.

     6.8 RECORDS AND AUDIT.

          (a) PRENDERGAST AND EDENLAND. During the Research Term and for two (2)
years thereafter, Prendergast and Edenland shall maintain complete and accurate
records pertaining to the Research and expenditures of funds to support the
Research, in sufficient detail to permit Hollis-Eden to confirm that the
payments made pursuant to Section 6.1 are being used solely to support the
Research and that the limitation of Section 6.1(c) has been respected.
Hollis-Eden shall have the right to cause an independent, certified public
accountant reasonably acceptable to Prendergast to audit such records to confirm
the use of the funds to support the Research and that the limitation of Section
6.1(c) has been respected. Such audits may be exercised twice per year, within
two (2) years after the period to which such records relate, upon reasonable
notice to Prendergast and during normal business hours. Hollis-Eden shall have
the right to itself inspect and copy, at any time during normal business hours,
such records described in this Section 6.8(a).

          (b) HOLLIS-EDEN. During the term of this Agreement and for a period of
two (2) years thereafter, Hollis-Eden shall keep complete and accurate records
pertaining to the sale or other disposition of the Products commercialized by
it, in sufficient detail to permit Edenland to confirm the accuracy of all
payments due hereunder. Edenland shall have the right to cause an independent,
certified public accountant reasonably acceptable to Hollis-Eden to audit such
records to confirm Hollis-Eden's Net Sales and royalty payments owed hereunder;
provided, however, that such auditor shall not disclose any confidential
information of Hollis-Eden to Prendergast or Edenland, except to the extent such
disclosure is necessary to verify the amount of royalty payments due under this
Agreement. Hollis-Eden will ensure that any agreement entered into between
Hollis-Eden and a licensee or sublicensee of Hollis-Eden shall include a
provision giving Hollis-Eden similar inspection rights with respect to such
licensee's or sublicensee's applicable records. Such records subject to
inspection by Hollis-Eden shall also be subject to audit by the accountant
referred to in the first sentence of this Section 6.8(b). Such audits may be
exercised once a year, within two (2) years after the period to which such
records relate, upon reasonable notice to Hollis-Eden and during normal business
hours. Any amounts correctly shown to be owing by such audits shall be paid
immediately with interest in the amount of [***] per month (or the maximum
amount permitted by law, if less) from the date first owed until paid.
Prendergast shall bear the full cost of such audit

                                      15.
<PAGE>

unless such audit discloses a variance in the amounts paid by Hollis-Eden of
more than [*****************] from the amount of royalties actually owed. In
such case, Hollis-Eden shall bear the reasonable cost of such audit.

     6.9 WITHHOLDING OF TAXES. Any withholding of taxes levied by tax
authorities on the payments hereunder shall be borne by Prendergast and deducted
by Hollis-Eden from the sums otherwise payable by it hereunder for payment to
the proper tax authorities on behalf of Prendergast. Hollis-Eden agrees to
cooperate with Prendergast in the event Prendergast claims exemption from such
withholding or seeks deductions under any double taxation or other similar
treaty or agreement from time to time in force, such cooperation to consist of
providing receipts of payment of such withheld tax or other documents reasonably
available to Hollis-Eden.

     6.10 BLOCKED CURRENCY. In each country where the local currency is
blocked and cannot be removed from the country, royalties accrued in that
country may be paid to Prendergast in the country in local currency by deposit
in a local bank designated by Prendergast.

7. PATENT MATTERS

     7.1 DRAFT PROVISIONAL APPLICATION. Prendergast shall have the right to
draft and submit to Hollis-Eden initial provisional patent applications covering
any Compound within the Research Results. Such initial draft provisional patent
application shall describe the invention and any data available at that time to
demonstrate, support, or enable disclosure of such invention. Hollis-Eden shall
reasonably consider such provisional patent applications in Hollis-Eden's own
drafting of any provisional or non-provisional patent applications claiming such
inventions within the Research and, to the extent permitted by applicable law,
Patrick T. Prendergast shall be acknowledged as inventor on all such
applications utilizing any data or information or concepts or content of the
provisional provided to Hollis-Eden by Prendergast. Notwithstanding the
foregoing, if (i) Hollis-Eden sends a written notice to Prendergast requesting
that he draft an initial provisional patent application covering a Compound and
(ii) Hollis-Eden does not receive such initial draft from Prendergast within
thirty (30) days of Hollis-Eden's notice, then Hollis-Eden shall have the right
to draft the initial provisional patent application for such Compound.

7.2 FILING AND PROSECUTION.

          (a) GENERAL. Hollis-Eden shall have the sole and exclusive right, but
not the obligation, to conduct and control, at its expense, the filing,
prosecution and maintenance of any patents filed on, or other applications or
registrations with respect to,

                                      16.
<PAGE>

the Research Results, including the Research Patents. During the term of this
Agreement, Hollis-Eden shall reasonably consider any recommendations provided by
Prendergast regarding patent filing and/or prosecution of the Research Patents,
but sole discretion as to filing and/or prosecution matters shall rest with
Hollis-Eden. Hollis-Eden shall use reasonable efforts to provide Prendergast
with copies of documents, correspondence and materials reasonably relating to
the prosecution by Hollis-Eden of the Research Patents to allow Prendergast a
reasonable time to review such materials and comment thereon. Prendergast shall
provide Hollis-Eden all reasonable assistance, at Hollis-Eden's expense, in
prosecuting such patents, including without limitation executing all documents
and instruments reasonably required for such prosecution.

          (b) CERTAIN PATENTS. If Hollis-Eden, in its sole discretion, decides
that it no longer desires to prosecute or maintain any patent or application
within the Research Patents or the Patents and Applications, Hollis-Eden shall
so notify Prendergast. Prendergast shall then have the right to assume
prosecution and maintenance of such specific patent or application. Hollis-Eden
shall, upon Prendergast's request, take all actions and execute all documents
and instruments reasonably necessary to transfer such right to prosecute and
maintain, on Hollis-Eden's behalf, such specific patents and applications to
Prendergast. For any such patent application for which Prendergast has
undertaken under this subsection (b) to continue prosecution efforts,
Prendergast shall provide to Hollis-Eden copies of all documents, correspondence
and materials reasonably relating to the prosecution by Prendergast of such
patent applications in sufficient time to allow Hollis-Eden to review such
materials and comment thereon. Prendergast shall reasonably consider and
accommodate any recommendations provided by Hollis-Eden regarding patent filing
and/or prosecution of such patent applications. In addition, if Hollis-Eden has
a reasonable justification for any changes to such prosecution based on
Hollis-Eden's own patent prosecution and enforcement strategy, then Prendergast
will modify or change any such prosecution efforts as requested by Hollis-Eden,
including without limitation deleting or amending particular claims in such
applications and/or modifying any arguments made in communications with relevant
patent authorities. For clarity, it is understood and agreed that the foregoing
right in this subsection (b) of Prendergast to undertake to continue the
prosecution and maintenance, on Hollis-Eden's behalf, of specific patents and
patent applications does not affect the licenses granted to Hollis-Eden under
this Agreement.

     7.3 INFRINGEMENT OF PATENTS BY THIRD PARTIES. Prendergast shall promptly
notify Hollis-Eden in writing of any alleged or threatened infringement of the
Research Patents of which he becomes aware. Prendergast hereby agrees to
cooperate reasonably in any litigation or other legal action related to
enforcing the Research Patents as reasonably requested by Hollis-Eden,
including, if required, himself bringing a legal

                                      17.
<PAGE>

action or furnishing a power of attorney at the expense of Hollis-Eden. Any
recovery from such infringer obtained by settlement or otherwise shall belong to
Hollis-Eden. Notwithstanding the foregoing sentence, to the extent that it can
be demonstrated with a preponderance of the evidence that any portion of such
recovery is based upon the loss of revenues of Hollis-Eden, then Edenland shall
be entitled to an amount of such recovery that is equal to the royalties that
would have been due under this Agreement with respect to the amount of such
recovery allocated to lost revenues, provided that Edenland must first reimburse
Hollis-Eden for Edenland's proportionate share (based on the proportion of the
recovery claimed by Edenland) of all litigation fees and costs incurred by
Hollis-Eden related to the infringement dispute.

     7.4 SUBLICENSES. Hollis-Eden shall have the sole and exclusive right, but
not the duty, to grant licenses under the Research Patents exclusively licensed
under this Agreement and to collect royalty payments therefor.

     7.5 RIGHT TO SUE. Prendergast and Edenland hereby grant to Hollis-Eden the
sole and exclusive right, but not the duty, to sue on the patents in the
Research Patents, and to collect all damages and profits for any past, present
and/or future infringements thereof.

     7.6 DEFENSE. Hollis-Eden shall have the sole and exclusive right, but not
the duty, to bring and maintain any action necessary to defend its rights to the
Research Patents, and/or the Know-How, including but not limited to actions in
copyright and trade secret.

     7.7 SOLE DISCRETION. Any such licenses or suits of Sections 7.4, 7.5,
and/or 7.6, respectively, shall be undertaken at Hollis-Eden's sole discretion.

     7.8 EDENLAND AND PRENDERGAST RIGHTS TO SUE AND DEFEND. Notwithstanding
Sections 7.5 and 7.6, if (i) any infringement or threatened infringement on the
Research Patents or the Know-How relating to the Research, which infringement
could reduce the amount of royalties due to Edenland under this Agreement, is
caused by anyone who is currently or was previously associated, affiliated or
employed with Hollis-Eden or its Affiliates ("Hollis-Eden Affiliate"), (ii)
Edenland or Prendergast notify Hollis-Eden in writing of its or his intent to
exercise their rights under this Section 7.8 and (iii) Hollis-Eden elects not to
exercise its rights under Sections 7.5 and 7.6 within 180 days after receipt of
the notice described in clause (ii) above, then Edenland and Prendergast shall
have the right to sue or defend against such Hollis-Eden Affiliate, at their
expense, as described in Sections 7.5 and 7.6.

12. MISCELLANEOUS

     12.1 PUBLICATION. Prendergast covenants and agrees that he and his
employees will not publish or disclose any Research or portion of the Research
Results unless Hollis-Eden has given Prendergast the prior written permission to
do so, which permission may be withheld at Hollis-Eden's sole discretion. To the
extent that Prendergast is an inventor of a Compound, Hollis-Eden shall give
Prendergast credit as inventor of such Compound in any publication by
Hollis-Eden regarding such Compound or a Product incorporating such Compound.

Agreement, the parties shall refer such dispute to the Chief Executive Officer
of Hollis-Eden and Prendergast for attempted resolution by good faith

dispute under the Agreement pursuant to good faith negotiation under Section

enforced in such jurisdiction as if such invalid, illegal or unenforceable part
or parts of this provision had never been contained herein, consistent with the
general intent of the Parties insofar as possible.

party.

     12.10 NON WAIVER. The failure of a party in any one or more instances to
insist upon strict performance of any of the terms and conditions of this

right to assert or rely upon any such terms or conditions on any future
occasion.

     12.11 DISCLAIMER OF AGENCY. Neither party is, nor will be deemed to be, the
legal representative or agent of the other, nor shall either party have the
right or authority to assume, create, or incur any third party liability or
obligation of any kind, express or implied, against or in the name of or on
behalf of another except as expressly set forth in this Agreement.

     12.12 SEVERABILITY. If a court of competent jurisdiction declares any
provision of this Agreement invalid or unenforceable, or if any government or
other agency having jurisdiction over either Hollis-Eden or Hollis-Eden deems
any provision to be contrary to any laws, then that provision shall be severed
and the remainder of the Agreement shall continue in full force and effect. To
the extent possible, the parties shall revise such invalidated provision in a
manner that will render such provision valid without impairing the parties'
original intent.

     12.13 AFFILIATES; ASSIGNMENT. Prendergast may not assign his rights or
delegate his duties under this Agreement without the prior written consent of
Hollis-Eden. Hollis-Eden may assign this Agreement to any of its Affiliates or
