                        Georgetown's Right Of Publication

8.1      Samaritan recognizes that consistent with Georgetown's status as an
         educational institution and the principles of academic freedom,
         Georgetown requires that its researchers be free to publish the results
         of their research activities. Samaritan agrees that researchers engaged
         in the Sponsored Research shall be permitted to publish in journals,
         theses, dissertations, or other format of their own choosing, and to
         present at symposia and national or regional professional meetings, the
         methods and results of the Sponsored Research, provided, however, that
         Samaritan shall have been furnished copies of any proposed publication
         or presentation at least thirty (30) days in advance of the submission
         of such proposed publication or presentation to a journal, editor, or
         other third party. Any such proposed publication or presentation shall
         state the name of the Principal Investigator and state that the
         research giving rise to such proposed publication or presentation was
         supported by Samaritan under this Agreement. The right of publication
         by Georgetown or its faculty, staff, employees or students, as
         indicated in this Article, shall not be affected by any license granted
         to Samaritan under Article 5 hereof.

8.2      Samaritan shall have thirty (30) days after receipt of the copies of
         any proposed publication or presentation to object to the proposed
         presentation or publication because there is patentable or proprietary
         information which is Samaritan's Confidential Information or
         information which related to or arises out of the Sponsored Research
         contained in such proposed publication or presentation that Samaritan
         has a reasonable business interest in keeping confidential. In the
         event Samaritan makes such an objection, Georgetown and its researchers
         shall refrain from making such publication or presentation until the
         parties can agree on a reasonable limitation on such disclosure, until
         a patent application directed to the patentable subject matter
         contained in the proposed publication or presentation can be filed with
         the United States Patent and Trademark Office and/or foreign patent
         offices, or until Dr. Papadopoulos gives his written approval therefore
         after consultation with and notice to Samaritan.


                                    ARTICLE 9
                                   Use Of Name

9.1      Georgetown and Samaritan shall obtain the prior written permission from
         each other before using the name, symbols and/or marks of the other in
         any form of publicity in connection with this Agreement, the Sponsored
         Research or any license grant hereunder. This shall not include legally
         required disclosure by Georgetown or Samaritan that identifies the
         existence of the Agreement, reports generated in the normal course of
         business by Georgetown or Samaritan, or where acknowledgment of the
         Agreement or the Sponsored Research is required by the guidelines of a
         scientific publication or organization. Samaritan may use the name of
         Dr. Papadopoulos in connection with his status as a director, officer
         or scientific advisor to Samaritan. Georgetown acknowledges that
         Samaritan is a publicly traded company and shall be required by law and
         applicable regulations to make disclosures relating to this Agreement
         and the Sponsored Research.

9.2      Samaritan shall not use, nor authorize others to use, the name,
         symbols, or marks of Georgetown in any advertising or publicity
         material or make any form of representation or statement in relation to
         this Agreement or the Sponsored Research that would constitute an
         express or implied endorsement by Georgetown of any commercial product
         or service, without prior written approval from Georgetown.

         amount required by the laws of the state or commonwealth in which
         Georgetown's workers are located.

10.2     Upon request, Georgetown shall provide evidence of its insurance or
         self-insurance coverage and unless self-insured, will provide to

         its coverage.

         days prior written notice if Samaritan fails to pay to Georgetown such
         amount within such 60-day period.

11.4     Samaritan shall notify Georgetown immediately upon the occurrence or
         expected occurrence of any of the following events: (i) a petition in
         bankruptcy is filed by or against Samaritan; or (ii) Samaritan makes an
         assignment for the benefit of creditors. Regardless of whether such
         notice is given, Georgetown shall have a right to terminate the
         Sponsored Research under this Agreement immediately by written notice
         to Samaritan upon the occurrence of any of the foregoing events.

11.6     Termination of the Sponsored Research under this Agreement by either
         party shall mean that all rights and obligations of either party under
         Articles 2 and 3 (except Samaritan's obligations under Section 3.2
         shall survive) hereof shall be terminated in full on the effective
         date. Termination of the Sponsored Research under this Agreement by
         either party shall not affect any rights or obligations of the parties
         accrued prior to the effective date of any termination of the Sponsored

         Agreement other than the rights and obligations under Articles 2 and 3
         hereof, shall survive the termination of the Sponsored Research under
         this Agreement. Each license granted or to be granted under Article 5
         hereof shall not be terminated or in any way effected if the Sponsored
         Research is terminated or this Agreement is terminated. Each such
         license shall have its own termination provisions as set forth in the
         respective license.

Georgetown at the time the Sponsored Research is terminated or completed.
Georgetown shall be permitted to keep the originals of any such records and

                         SAMARITAN PHARMACEUTICALS, INC.

                          COMMON STOCK PURCHASE WARRANT


500,000 Shares                                Original Issue Date: June 8, 2001

         This Common Stock Purchase Warrant ("Warrant") is issued in connection
with and pursuant to that certain Research Collaboration and Licensing Agreement
(the "Research Agreement") dated as of June 8, 2001, by and between SAMARITAN
PHARMACEUTICALS, INC., a Nevada corporation (the "Company") and GEORGETOWN
UNIVERSITY (the "Holder").

         FOR VALUE RECEIVED, the Holder, is entitled to purchase from the
Company, during the period specified in this Warrant, 500,000 fully paid and
non-assessable shares ("Warrant Shares") (subject to adjustment as hereinafter
provided) of common stock, par value $.001 per share, of the Company ("Common
Stock") at the purchase price per share provided in Section 1.2 of this Warrant
(the "Warrant Exercise Price"), all subject to the terms and conditions set
forth in this Warrant. All terms not otherwise defined herein shall have the
meaning ascribed to them in the Research Agreement.

Section 1.        Period for Exercise and Exercise Price.

     1.1 Period for Exercise. The right to purchase shares of Warrant Shares
represented by this Warrant shall be immediately exercisable, and shall expire
at 5:00 p.m., Eastern Time, May 31, 2011 (the "Expiration Date"). From and after
the Expiration Date this Warrant shall be null and void and of no further force
or effect whatsoever.

     1.2 Warrant Exercise Price. The Warrant Exercise Price per share of Warrant
Shares shall be $1.50 per share (subject to adjustment as hereinafter provided).


<PAGE>

Section 2.        Exercise of Warrant.

     2.1 Manner of Exercise. The Holder may exercise this Warrant, in whole or
in part, immediately, but not after the Expiration Date, during normal business
hours on any business day by surrendering this Warrant to the Company at the
principal office of the Company, accompanied by a Warrant Exercise Form in
substantially the form annexed hereto duly executed by the Buyer and by payment
of the Warrant Exercise Price for the number of shares of Warrant Shares for
which this Warrant is then exercisable, in immediately available funds,.

     2.2 When Exercise Effective. Each exercise of this Warrant shall be deemed
to have been effected on the day on which all requirements of Section 2.1 shall
have been met with respect to such exercise. At such time the person in whose
name any certificate for shares of Warrant Shares shall be issuable upon such
exercise shall be deemed for all corporate purposes to have become the Holder of
record of such shares, regardless of the actual delivery of certificates
evidencing such shares.

     2.3 Delivery of Stock Certificates. As soon as practicable after each
exercise of this Warrant, and in any event no later than 3 days after such
exercise, the Company at its expense will issue upon the Holder's submission of
the applicable Warrant Exercise Form, a certificate, registered in the name of
the Holder for the number of shares of common stock of the Company to which the
Buyer shall be entitled to upon such exercise.

Section 3. Adjustment of Purchase Price and Number of Shares. The Warrant
Exercise Price and the kind of securities issuable upon exercise of the Warrant
shall be adjusted from time to time as follows:

     3.1 Subdivision or Combination of Shares (Stock Splits). If the Company at
any time effects a subdivision or combination of the outstanding Common Stock
(through a stock split or otherwise), the number of shares of Warrant Shares
shall be increased, in the case of a subdivision, or the number of shares of
Warrant Shares shall be decreased, in the case of a combination, in the same
proportions as the Common Stock is subdivided or combined, in each case
effective automatically upon, and simultaneously with, the effectiveness of the
subdivision or combination which gives rise to the adjustment.

     3.2 Stock Dividends. If the Company at any time pays a dividend, or makes
any other distribution, to holders of Common Stock payable in shares of Common
Stock, or fixes a record date for the determination of holders of Common Stock
entitled to receive a dividend or other distribution payable in shares of Common
Stock, then the number of shares of Warrant Shares in effect immediately prior
to such action shall be proportionately increased so that the Holder hereof may
receive upon exercise of the Warrant the aggregate number of shares of Common
Stock which he or it would have owned immediately following such action if the
Warrant had been exercised immediately prior to such action. The adjustment
shall become effective immediately as of the date the Company shall take a
record of the holders of its Common Stock for the purpose of receiving such
dividend or distribution (or if no such record is taken, as of the effectiveness
of such dividend or distribution).

     3.3 Reclassification,  Consolidation or Merger. If at any time, as a result
of:

(a)  a capital  reorganization  or  reclassification  (other than a subdivision,
     combination or dividend provided for elsewhere in this Section 3), or

(b)  a merger or consolidation of the Company with another corporation  (whether
     or not the Company is the surviving corporation),

<PAGE>

the Common Stock issuable upon exercise of the Warrants shall be changed into or
exchanged for the same or a different number of shares of any class or classes
of stock of the Company or any other corporation, or other securities
convertible into such shares, then, as a part of such reorganization,
reclassification, merger or consolidation, appropriate adjustments shall be made
in the terms of the Warrants (or of any securities into which the Warrants are
exercised or for which the Warrants are exchanged), so that:

(y)  the Holders of Warrants or of such substitute securities shall thereafter
     be entitled to receive, upon exercise of the Warrants or of such substitute
     securities, the kind and amount of shares of stock, other securities, money
     and property which such Holders would have received at the time of such
     capital reorganization, reclassification, merger, or consolidation, if such
     Holders had exercised their Warrants immediately prior to such capital
     reorganization, reclassification, merger, or consolidation, and

(z)  the Warrants or such substitute securities shall thereafter be adjusted on
     terms as nearly equivalent as may be practicable to the adjustments
     theretofore provided in this Section 3.3.

     3.4 Other Action Affecting Common Stock. If at any time the Company takes
any action affecting its Common Stock, other than an action described in any of
Sections 3.1 - 3.3 which, in the opinion of the Board of Directors of the
Company (the "Board"), would have an adverse effect upon the exercise rights of
the Warrants, the Warrant Exercise Price or the kind of securities issuable upon
exercise of the Warrants, or both, shall be adjusted in such manner and at such
time as the Board may in good faith determine to be equitable in the
circumstances.

     3.5 Notice of Adjustments. Whenever the kind or number of securities
issuable upon exercise of the Warrants, or both, shall be adjusted pursuant to
Section 3, the Company shall deliver a certificate signed by its Chief Executive
Officer and by its Chief Financial Officer, setting forth, in reasonable detail,
the event requiring the adjustment, the amount of the adjustment, the method by
which such adjustment was calculated (including a description of the basis on
which the Board made any determination hereunder), and the Warrant Exercise
Price and the kind of securities issuable upon exercise of the Warrants after
giving effect to such adjustment, and shall cause copies of such certificate to
be mailed (by first class mail postage prepaid) to each Warrant Holder promptly
after each adjustment.

Section 4. Reservation of Stock, etc. The Company covenants and agrees that it
will at all times have authorized, reserve and keep available, solely for
issuance and delivery upon the exercise of this Warrant, the number of shares of
Warrant Shares from time to time issuable upon the exercise of this Warrant. The
Company further covenants and agrees that this Warrant is, and any Warrants
issued in substitution for or replacement of this Warrant and all Warrant
Shares, will upon issuance be duly authorized and validly issued and, in the
case of Warrant Shares, upon issuance will be fully paid and non-assessable and
free from all preemptive rights of any stockholder, and from all taxes, liens
and charges with respect to the issue thereof (other than transfer taxes).

Section 5.        Ownership, Transfer and Substitution of Warrants.

     5.1 Ownership of Warrants. The Company may treat the person in whose name
any Warrant is registered on the register kept at the principal office of the
Company as the owner and Holder thereof for all purposes, notwithstanding any
notice to the contrary, but in all events recognizing any transfers made in
accordance with the terms of this Warrant.

<PAGE>

     5.2 Transfer and Exchange of Warrants. Upon the surrender of any Warrant,
properly endorsed, for registration of transfer or for exchange at the principal
office of the Company, the Company at its expense will execute and deliver to
the Holder thereof, upon the order of such Holder, a new Warrant or Warrants of
like tenor, in the name of such Holder or as such Holder may direct, for such
number of shares with respect to each such Warrant, the aggregate number of
shares in any event not to exceed the number of shares for which the Warrant so
surrendered had not been exercised.

Section 6. No Rights or Liabilities as Shareholder. Nothing contained in this
Warrant shall be construed as conferring upon the Holder hereof any rights as a
shareholder of the Company or as imposing any liabilities on such holder to
purchase any securities or as a shareholder of the Company, whether such
liabilities are asserted by the Company or by creditors of the Company.

Section 7.        Miscellaneous.

     7.1 Amendment and Waiver. This Warrant may be amended with, and only with,
the written consent of the Company and the Holder. Any waiver of any term,
covenant, agreement or condition contained in this Warrant shall not be deemed a
waiver of any other term, covenant, agreement or condition, and any waiver of
any default in any such term, covenant, agreement or condition shall not be
deemed a waiver of any later default thereof or of any default of any other
term, covenant, agreement or condition.

     7.2 Representations and Warranties to Survive Closing. All representations,
warranties and covenants contained herein shall survive the execution and
delivery of this Warrant and the issuance of any Warrant Shares upon the
exercise hereof.

     7.3 Severability. In the event that any court or any governmental authority
or agency declares all or any part of any Section of this Warrant to be unlawful
or invalid, such unlawfulness or invalidity shall not serve to invalidate any
other Section of this Warrant, and in the event that only a portion of any
Section is so declared to be unlawful or invalid, such unlawfulness or
invalidity shall not serve to invalidate the balance of such Section.

     7.4 Binding Effect; No Third Party Beneficiaries. All provisions of this
Warrant shall be binding upon and inure to the benefit of the parties and their
respective heirs, legatees, executors, administrators, legal representatives,
successors, and permitted transferees and assigns. No person other than the
holder of this Warrant and the Company shall have any legal or equitable right,
remedy or claim under or in respect of, this Warrant.

required or permitted to be given under the terms of this Warrant must be in
writing and will be deemed to have been delivered: (i) upon receipt, when
delivered personally; (ii) upon receipt, when sent by facsimile (provided
confirmation of transmission is mechanically or electronically generated and

the recipient party has specified by written notice given to each other party
three (3) Trading Days prior to the effectiveness of such change. Written
confirmation of receipt (A) given by the recipient of such notice, consent,
waiver or other communication, (B) mechanically or electronically generated by
the sender's facsimile machine containing the time, date, and recipient
facsimile number or (C) provided by a nationally recognized overnight delivery
service, shall be rebuttable evidence of personal service, receipt by facsimile

with clause (i), (ii) or (iii) above, respectively.

<PAGE>

     7.6 Taxes, Costs and Expenses. The Company covenants and agrees that it
will pay when due and payable any and all federal, state and local taxes (other
than income taxes) and any other costs and expenses which may be payable in
respect of the preparation, issuance, delivery, exercise, surrender or transfer
of this Warrant pursuant to the terms of this Warrant or the issuance of any
shares of Warrant Shares as a result thereof. If any suit or action is
instituted or attorneys employed to enforce this Warrant or any part thereof,
the Company promises and agrees to pay all costs and expenses associated
therewith, including reasonable attorneys' fees and court costs.

     7.7 Loss of Warrant. Upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this
Warrant, and (in the case of loss, theft or destruction) of indemnification in
form and substance acceptable to the Company in its reasonable discretion, and
upon surrender and cancellation of this Warrant, if mutilated, the Company shall

     7.8 Headings. The headings used herein are used for convenience only and
