stock,  no  par  value  ("Common  Stock"),  of  Epitope,  Inc.  (the  "Company")
originally  issued by the  Company on July 23,  1993,  and the  related  Warrant
Agreements ("Warrant Agreements") dated as of the same date containing the terms

                             [name of warrantholder]

or registered assigns, is the registered holder of the number of Warrants (each,
a  "Warrant,"  and  collectively,  "Warrants")  set forth  above.  Each  Warrant
represented by this certificate for Warrants ("Warrant  Agreement") entitles the
registered holder thereof (the "Warrantholder") to purchase from Epitope,  Inc.,
a corporation  incorporated  under the laws of the state of Oregon  ("Company"),
United States of America  ("U.S."),  one fully paid and  nonassessable  share of
common stock, no par value, of the Company  ("Common  Stock") upon  presentation
and  surrender  of this  Warrant  Agreement  with the  accompanying  Election to
Exercise  Warrants duly  completed,  at any time after the Common Stock issuable
upon  exercise of this  Warrant has been  approved  for  quotation on The Nasdaq
Stock Market, and prior to 5 P.M., U.S. Pacific time, on the Expiration Date (as
defined  in Section  2), at the  corporate  offices of the  Company at 8505 S.W.
Creekside  Place,  Beaverton,  Oregon 97008,  or at such other address as may be
specified by the Company  pursuant to Section 9,  accompanied  by payment of the
Exercise Price (as defined herein) and any applicable  taxes,  either in cash in
U.S.  funds or by certified or official bank check in U.S.  funds payable to the
order of the  Company.  These  Warrants  are issued  pursuant to a 1993  Warrant
Purchase  Agreement  ("Purchase  Agreement") among the Company and the Investors
described therein dated as of July 6, 1993.

      Section 1. Exercise  Price.  Each Warrant  entitles the  Warrantholder  to
purchase  one share of Common  Stock for U.S.  $_____  (the  "Exercise  Price"),
subject to adjustment as provided herein.

      Section 2. Expiration. All Warrants not theretofore exercised shall expire
at 5 p.m.,  U.S.  Pacific  time,  on the  earlier  of the  following  dates (the
"Expiration Date"): (a) September 30, 2000, and (b) the expiration of 120



                                      - 1 -





days after the first period of 20  consecutive  trading days during which period
the average of the high and low sales  prices of the Common  Stock on The Nasdaq
Stock  Market,  or any other  exchange  or national  market  system on which the
Common Stock is then traded, is at least $30.00.

      Section  3.  Adjustments  of  Number  and Kind of Shares  Purchasable  and
Exercise Price. The number and kind of securities or other property  purchasable
upon exercise of a Warrant shall be subject to adjustment from time to time upon
the occurrence, after the date hereof, of the following events:

            3.1 If the  outstanding  shares of the  Company's  Common  Stock are
      divided  into a greater  number of shares or a dividend in Common Stock is
      paid on the Common Stock, the number of shares of Common Stock issuable on
      exercise  of the  Warrants  shall  be  proportionately  increased  and the
      Exercise Price in effect  immediately  prior to such subdivision or at the
      record date of such dividend shall,  simultaneously with the effectiveness
      of such subdivision or immediately after the record date of such dividend,
      be proportionately reduced; and, conversely,  if the outstanding shares of
      Common Stock are combined into a smaller number of shares of Common Stock,
      the  number of  shares  of Common  Stock  issuable  upon  exercise  of the
      Warrants shall be proportionately reduced and the Exercise Price in effect
      immediately  prior  to such  combination  shall,  simultaneously  with the
      effectiveness  of such  combination,  be  proportionately  increased.  The
      increases and reductions provided for in this subsection 3.1 shall be made
      with the intent and, as nearly as practicable, the effect that neither the
      percentage of the total equity of the Company  issuable on exercise of the
      Warrants  nor the price  payable for such  percentage  upon such  exercise
      shall be affected by any event described in this subsection 3.1.

            3.2 No adjustment  of the Exercise  Price will be made if the amount
      of the  adjustment is less than U.S. $.01 per share,  but in that case any
      adjustment  that would  otherwise  be  required to be made will be carried
      forward  and  will be  made at the  time of and  together  with  the  next
      adjustment  of the Exercise  Price  which,  together  with any  adjustment
      carried forward, amounts to U.S. $.01 per share or more.

            3.3 In case of any change in the Common Stock of the Company through
      merger,  consolidation,   reclassification,   reorganization,  partial  or
      complete  liquidation,  or other  change in the capital  structure  of the
      Company  (not  including  a  combination  of  shares  or the  issuance  of
      additional  shares of Common  Stock by the Company by stock split or stock
      dividend),  then, as a condition of the change in the capital structure of
      the  Company,  provision  shall be made so that the holder of this Warrant
      Agreement  will have the right  thereafter to receive upon the exercise of
      the Warrants the kind and amount of shares of stock or other securities or
      property to which such holder  would have been  entitled  if,  immediately
      prior to such  merger,  consolidation,  reclassification,  reorganization,
      recapitalization,  or other change in the capital  structure,  such holder
      had held the number of shares of Common Stock  issuable  upon the exercise
      of the Warrants. In any such case, appropriate adjustment shall be made in
      the  application  of the  provisions  set forth herein with respect to the
      rights and interest  thereafter of the Warrantholder,  to the end that the
      provisions set forth herein shall  thereafter be applicable,  as nearly as
      reasonably  may be, in relation  to any shares of stock or other  property
      thereafter deliverable upon the exercise of the Warrants. The Company will
      not permit any change in its capital  structure to occur unless the issuer
      of the shares of stock or other securities to be received by the holder of
      this  Warrant  Agreement,  if not the  Company,  agrees to be bound by and
      comply with the provisions of this Warrant Agreement.

            3.4 When any  adjustment  is  required  to be made in the  number of
      shares of Common Stock,  other  securities,  or property  purchasable upon
      exercise of the  Warrants,  the Company shall  promptly  determine the new
      number of shares or other securities or property purchasable upon exercise
      of the Warrants and (a) prepare and retain on file a statement  describing
      in  reasonable  detail the method  used in  arriving  at the new number of
      shares or other securities or property



                                      - 2 -





      purchasable  upon  exercise of the  Warrants  and (b) cause a copy of such
      statement to be mailed to the Warrantholder  within thirty (30) days after
      the date when the event giving rise to the adjustment occurred.

            3.5 No fractional  shares of Common Stock or other  securities shall
      be issued in connection with the exercise of any Warrants, but the Company
      shall pay, in lieu of fractional  shares,  a cash payment  therefor on the
      basis of the closing  price on a national  securities  exchange on the day
      immediately  prior to exercise or, if the Common Stock or other securities
      are not traded on a national securities exchange on such day, on the basis
      of the fair market value  thereof as  determined by the board of directors
      of the Company, which determination shall be conclusive.

            3.6 Notwithstanding  anything herein to the contrary, there shall be
      no  adjustment  made  hereunder on account of the sale and issuance of the
      shares of Common Stock or other  securities  purchasable  upon exercise of
      the Warrants.

      Section  4.  Rights of  Warrantholder  as  Shareholder.  No holder of this
Warrant Agreement shall, as such, be entitled to vote, receive dividends,  or be
deemed the holder of Common  Stock or any other  securities  of the Company that
may at any time be issuable on the exercise hereof for any purpose whatever, nor
shall anything  contained  herein be construed to confer upon the holder of this
Warrant Agreement, as such, any of the rights of a shareholder of the Company or
any right to vote for the election of directors or upon any matter  submitted to
shareholders at any meeting thereof or give or withhold consent to any corporate
action (whether upon any matter submitted to shareholders at any meeting thereof
or otherwise)  including,  without limitation,  giving or withholding consent to
any  merger,  recapitalization,  issuance of stock,  reclassification  of stock,
exchange of stock, change of stock to par value, consolidation or conveyance, or
to receive  notice of meetings or other  actions  affecting  shareholders  or to
receive dividends or subscription rights or other distributions.

      Section 5. Payment of Certain Taxes and Charges.  The Company shall not be
required to issue or deliver any certificate for shares of Common Stock or other
securities upon the exercise of Warrants  evidenced by this Warrant Agreement or
to register the transfer of the Warrants  evidenced  hereby until any applicable
transfer tax and any other taxes or governmental charges that the Company may be
required by law to collect in respect of such  exercise  or transfer  shall have
been paid, such tax being payable by the holder of this Warrant Agreement at the
time of surrender for exercise or transfer.

      Section 6. Registration. The Company has prepared a registration statement
on Form S-3 (the  "Registration  Statement")  under the 1933 Act with respect to
the  resale  by the  Warrantholder  of the  Warrants  covered  by  this  Warrant
Agreement  and of the shares of Common Stock issued or issuable upon exercise of
this Warrant Agreement (the "Warrant Shares").  As soon as practicable after the
original issue date of this Warrant  Agreement (the "Original Issue Date"),  the
Company  shall file the  Registration  Statement  with the U.S.  Securities  and
Exchange  Commission  and shall use its best  efforts to cause the  Registration
Statement  to become  effective  under the 1933 Act as promptly  as  practicable
after the Original  Issue Date as provided for in, and in accordance  with,  the
terms and conditions of the Purchase Agreement.

      Company shall not be affected by any notice to the contrary.

            7.2  Exchange.  Subject to the  provisions  of  Section  7.4 and the
      restrictions  on  the  first  page  hereof,   this  Warrant  Agreement  is

                                      - 3 -





      for Warrant  Agreements to purchase the same aggregate number of shares of
      Common Stock as are purchasable  hereunder,  each new Warrant Agreement to

            7.3 Securities Act of 1933. The Warrantholder, by acceptance hereof,
      agrees that this Warrant  Agreement  and the shares of Common Stock issued
      or issuable upon exercise of this Warrant  Agreement may not be offered or

      the Company's making a notation on its records and on the certificates for

      implement such restriction on transferability.

            7.4 Minimum Warrant Agreement Amount. Notwithstanding the provisions
      of Section 7.1 and Section 7.2, the Company shall not be required to issue
      a Warrant Agreement for Warrants covering less than 1,000 shares of Common
      Stock,  except in the case of a partial  exercise by the  Warrantholder of
      this Warrant  Agreement that leaves Warrants  exercisable to purchase less
      than  1,000  shares  that  are to  remain  registered  in the  name of the
      exercising Warrantholder,  and any subsequent partial exercise,  transfer,
      or exchange of such Warrant Agreement.

            7.5 No Transfer of Common Stock for 60 Days.  Common Stock purchased
      pursuant to the  exercise of these  Warrants  may not be sold or otherwise
      transferred  or  disposed  of for a period  of 60 days  after  the date of
      purchase of such Common Stock.
