      --------------------------------------------------------------------

                                  INTRODUCTION

            Certain  of the  Stockholders  are  party  to a Share  Exchange  and
Reorganization Agreement, dated as of August 25, 2004 (the "Share Exchange"), by
and among the Company, Advaxis and such Stockholders,  pursuant to which (a) the
Company will acquire all of the issued and  outstanding  shares of capital stock
of Advaxis in exchange for shares of the Company's common stock, and (b) Advaxis
will become as a wholly-owned subsidiary of Company (the "Acquisition");

            The  Company  has  entered  into that  certain  Securities  Purchase
Agreement,  dated as of September 14, 2004 (the  "Purchase  Agreement"),  by and
between the Company  and the  investors  signatory  thereto  (collectively,  the
"Investors"), pursuant to which the Company is offering to sell to the Investors
a minimum of  $1,500,000  of its  securities  and a maximum of $7,000,000 of its
securities  (subject  to an  increase  to  $10,000,000  at the  election  of the
Company) (the "Offering");

            Pursuant  to  Section  5.1(k)  of the  Purchase  Agreement,  it is a
condition  precedent  to  the  Initial  Closing  (as  defined  in  the  Purchase
Agreement)  of the Offering that the  Stockholders  agree in writing not to sell
any of their  interests in the Company  until such time as there shall have been
filed  with  and  declared  effective  by  the  Securities  and  Commission,   a
registration  statement  in respect of the  Shares (as  defined in the  Purchase
Agreement) purchased by the Investors thereunder.

            The  Stockholders  acknowledge and agree that they will benefit from
the  consummation  of the  Offering  and, in order to induce the Company and the
Investors to consummate the Offering contemplated by the Purchase Agreement, and
for other good and valuable consideration,  the receipt and sufficiency of which
are acknowledged, the parties hereto agree as follows:

                                    AGREEMENT

            SECTION  1.  Definitions.  Capitalized  terms  used  herein  and not
otherwise defined herein shall have the meaning given such terms in the Purchase
Agreement to the extent the same are defined therein.

            SECTION 2.  Standstill.  Each  Stockholder  agrees not to effect any

such securities, during the period from the closing of the Acquisition until the
earlier of (i) the date that a registration statement with respect to the Shares
purchased by the  Investors  pursuant to the Purchase  Agreement  has been filed
with and declared  effective by the Securities and Exchange  Commission and (ii)
the first year anniversary of the date hereof, unless (a) such sale, transfer or
distribution is approved in writing by a Majority of the Investors,  and (b) the
transferee of such sold, transferred or distributed securities agrees in writing
to be bound by the  terms of this  Agreement  to the same  extent as if they had
originally been a party hereto.


            SECTION 3.  Further  Assurances.  Each party  agrees to execute such

            (b)  Assignment.  This  Agreement  may not be assigned or  otherwise
transferred,  nor,  except as  expressly  provided  hereunder,  may any right or
obligations  hereunder be assigned or  transferred  by either party  without the
prior written  consent of the other party.  Any permitted  assignee shall assume

            (d) Severability.  If one or more provisions of this Agreement be or
become invalid,  the parties hereto shall substitute,  by mutual consent,  valid
provisions for such invalid  provisions which valid provisions in their economic

reasonably  assumed that the parties would have entered into this Agreement with
such provisions.  In case such provisions  cannot be agreed upon, the invalidity
of one or several  provisions of this Agreement shall not affect the validity of
this Agreement as a whole,  unless the invalid  provisions are of such essential
importance  to this  Agreement  that it is to be  reasonably  assumed  that  the
parties  would  not  have  entered  into  this  Agreement  without  the  invalid
provisions.

            (e) Waiver. The waiver by either party hereto of any right hereunder
or the  failure to perform or of a breach by the other party shall not be deemed
a waiver of any other right  hereunder or of any other breach or failure by said
other party whether of a similar nature or otherwise.

            (f) Entire Agreement. This Agreement is the agreement referred to in
Section  5.1(k)  of the  Purchase  Agreement  and,  together  with the  Purchase
Agreement,  contains the entire understanding of the parties with respect to the
subject matter  hereof.  All express or implied  agreements and  understandings,
either  oral or  written,  heretofore  made  are  expressly  superseded  by this
Agreement. This Agreement may be amended, or any term hereof modified, only by a
written  instrument duly executed by both parties hereto and the written consent
of a Majority of Investors. No prior drafts of this Agreement may be used in the
construction or interpretation of this Agreement.

            (g) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK (WITHOUT  GIVING EFFECT TO
ANY CHOICE OR CONFLICT OF LAWS PROVISIONS).

            (h) CONSENT TO JURISDICTION.  EACH OF THE PARTIES HEREBY IRREVOCABLY
AND UNCONDITIONALLY SUBMITS TO THE JURISDICTION OF ANY FEDERAL OR STATE COURT OF
NEW YORK  SITTING IN NEW YORK CITY AND  IRREVOCABLY  AGREES  THAT ALL ACTIONS OR
PROCEEDINGS  ARISING OUT OF OR RELATING TO THIS  AGREEMENT  OR THE  TRANSACTIONS
CONTEMPLATED  HEREBY SHALL BE LITIGATED  EXCLUSIVELY IN SUCH COURTS. EACH OF THE
PARTIES  AGREES NOT TO COMMENCE ANY LEGAL  PROCEEDING  RELATED  HERETO EXCEPT IN
SUCH COURT.  EACH OF THE PARTIES  IRREVOCABLY  WAIVES ANY OBJECTION WHICH IT MAY
NOW OR HEREAFTER  HAVE TO THE LAYING OF THE VENUE OF ANY SUCH  PROCEEDING IN ANY
SUCH COURT AND HEREBY FURTHER IRREVOCABLY AND UNCONDITIONALLY  WAIVES AND AGREES
NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY SUCH ACTION, SUIT OR PROCEEDING
BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.


            (i) WAIVER OF JURY TRIAL.  EACH PARTY HERETO HEREBY  WAIVES,  TO THE
FULLEST EXTENT  PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
