                                    --------

Secured Party.

      1. Certain Definitions. UNLESS OTHERWISE DEFINED IN THIS PLEDGE AGREEMENT,
ANY  CAPITALIZED  TERM USED IN THIS PLEDGE  AGREEMENT HAS THE MEANING GIVEN THAT
TERM  IN THE  UCC.  If the  definition  given  a term  in  Chapter  9 of the UCC
conflicts with the  definition  given that term in any other chapter of the UCC,
the Chapter 9 definition shall control. As used in this Pledge Agreement:

for banking business.

            "Collateral" means all of Pledgors' right, title and interest in and
to the Pledged Membership  Interests,  including  after-acquired  Collateral and
proceeds of the Collateral.

            "Default" means an "Event of Default" hereunder or under the Note.

            "Obligation" means all obligations of Pledgors and Debtor under this
Pledge Agreement and Debtor under the Note,  including without limitation,  full

receivable or otherwise  distributed in respect of or in exchange of any Pledged
Membership Interests.

<PAGE>

            "Pledgors" includes,  without limitation,  each of the Pledgors as a
debtor-in-possession,   and  any  receiver,  trustee,  liquidator,  conservator,
custodian,  or similar party  hereafter  appointed for either  Pledgor or all or
substantially  all  of  such  Pledgor's  assets  pursuant  to  any  liquidation,
conservatorship,    bankruptcy,   moratorium,    rearrangement,    receivership,
insolvency, reorganization, or similar law from time to time in effect affecting
the rights of creditors generally.

            "Security  Interest"  means the security  interests  granted and the
transfers,  pledges  and  collateral  assignments  made under  Section 3 of this
Pledge Agreement.

            "UCC"  means (a)  generally,  and with  respect  to the  definitions
above, the Uniform Commercial Code, as adopted in Nebraska, as amended from time
to time,  and (b) with  respect  to rights in states  other than  Nebraska,  the
Uniform Commercial Code as enacted in the applicable state, as amended from time
to time.

      2. Promissory  Note. This Pledge Agreement is being executed and delivered
to secure the full payment of all of Debtor's obligations under the Note.

      3. Security Interest. In order to secure the full and complete payment and
performance  of the  Obligation  when due,  each of the Pledgors has delivered a
power signed in blank in the form attached hereto as Exhibit A and hereby grants
to Secured Party a first priority  security interest in, and pledges and assigns
to Secured Party:  (a) the Collateral,  and (b) all present and future accounts,
contract rights,  general intangibles,  chattel paper,  documents,  instruments,
cash and noncash proceeds and other rights arising from or by virtue of, or from
the voluntary or involuntary  sale or other  disposition of, or collections with
respect to, or claims against any other person with respect to, the  Collateral.
Such security  interest is granted,  and such pledge and assignment are made, as
security only.

      4. No Assumption or Modification. The Security Interest is given to secure
the prompt, unconditional and complete payment and performance of the Obligation
when due, and is given as security only. Secured Party does not assume and shall
not be liable for any of Pledgors' liabilities,  duties, or obligations under or
in connection  with the Collateral.  Secured  Party's  acceptance of this Pledge
Agreement, or its taking any action in carrying out this Pledge Agreement,  does
not constitute  Secured  Party's  approval of the Collateral or Secured  Party's
assumption of any obligation  under or in connection with the  Collateral.  This
Pledge Agreement does not affect or modify Pledgors' obligations with respect to
the Collateral.

      5.  Representations and Warranties.  Debtor hereby represents and warrants
to Secured Party as follows:

            (a) The Pledged  Membership  Interests are duly authorized,  validly
issued, fully paid and non-assessable, and their transfer thereof is not subject
to any restrictions other than restrictions imposed by applicable securities and
limited liability company laws.

            (b) Pledgors own the Collateral free and clear of all liens.

            (c) The information  contained in Schedule 1 attached to this Pledge
Agreement  is true and accurate and  sufficiently  describes  all of the Pledged
Membership Interests.

      6. Covenants. Debtor covenants that it will:

                                       2
<PAGE>

            (a)  Promptly  notify  Secured  Party of any  change  in any fact or
circumstances  represented  or warranted by Debtor herein with respect to any of
the Collateral.

            (b) Promptly notify Secured Party of any claim, action or proceeding
affecting  the  Security  Interest  and the  pledge  and  assignment  made under
Paragraph  3 or title to all or any of the  Collateral  and,  at the  request of
Secured Party,  appear in and defend,  at Debtor's  expense,  any such action or
proceeding.

            (c) Not permit Pledgors to sell, assign or otherwise dispose of any
Collateral.

            (d) Not  permit  Pledgors  to  create,  incur or suffer to exist any
other lien upon any of the Collateral except in favor of Secured Party.

            (e) At Debtors expense and at Secured Party's request, file or cause
to be filed such  applications  and take such other actions as Secured Party may
request to obtain the  consent or approval  of any  tribunal to Secured  Party's
rights  hereunder,  including,  without  limitation,  the  right to sell all the
Collateral  upon a Default  without  additional  consent or  approval  from such
tribunal (and,  because Debtor and Pledgors agree that Secured Party's  remedies
at law  for  failure  of  Pledgors  to  comply  with  this  provision  would  be
inadequate,  Debtor and Pledgors  agree that the covenants in this provision may
be specifically enforced).

            (f) From time to time  promptly  obtain from Pledgors and deliver to
Secured Party all such other  powers,  assignments,  certificates,  supplemental
documents,  and financing statements (if appropriate),  and do all other acts or
things as Secured  Party may  reasonably  request in order to more fully create,
evidence, perfect, continue and preserve the priority of the Security Interest.

      7.  Default;  Remedies.  Upon a breach by  Debtor  of any  representation,
warranty or covenant in the Note or in this Pledge Agreement (each such event, a
"Default") beyond any applicable grace period, if any, Secured Party may, at its
election,  exercise any and all rights  available  to a secured  party under the
UCC, in addition to any and all other  rights  afforded by the Note,  at law, in
equity,  or  otherwise,  including,  without  limitation,  exercising  the Power
executed in blank by Pledgors in respect of the Pledged Membership Interests,  a
form of which is attached as Annex "A" to this Pledge Agreement,  or applying by
appropriate  judicial  proceedings for appointment of a receiver for all or part
of the  Collateral  (and  Pledgors  hereby  consent  to any  such  appointment).
Notwithstanding  any provision of the Note, this Pledge  Agreement or otherwise,
the  pledge  of the  Collateral  under  this  Pledge  Agreement  is  made  as an
accommodation  to Debtor and is without  recourse  to either  Pledgor  under any
circumstance,  and  there  shall be no  personal  liability  on  Pledgors  or on
Debtor's  successors in title or assigns of the properties of Debtor, to pay the
indebtedness  evidenced by the Note, or for the observance or performance of any
of the covenants,  conditions or agreements  contained therein or in this Pledge
Agreement,  or in any other  instrument  evidencing or securing the indebtedness
evidenced by the Note,  or executed in connection  therewith,  and Secured Party
and any  subsequent  holder of the Note will look solely to the  Collateral  and
will not seek any money judgment,  deficiency or otherwise,  against Pledgors or
Debtor's  successors  in title or assigns of the  properties  of Debtor,  in the
event of default in the payment of the indebtedness  evidenced by the Note or in
the event of any default  under the terms of this Pledge  Agreement or any other
instrument  evidencing or securing the indebtedness  represented by the Note, or
executed in connection therewith.

                                       3
<PAGE>

            (a)  Notice.  Reasonable  notification  of the time and place of any
public sale of the  Collateral,  or  reasonable  notification  of the time after
which any private sale or other intended  disposition of the Collateral is to be
made,  shall be sent to Debtor and each of the  Pledgors and to any other person
entitled  to  notice  under  the  UCC;  provided  that if any of the  Collateral
threatens to decline  speedily in value or is of the type  customarily sold on a
recognized market, Secured Party may sell or otherwise dispose of the Collateral
without notification,  advertisement,  or other notice of any kind. It is agreed
that notice sent or given not less than five  Business  Days prior to the taking
of the action to which the notice relates is reasonable for the purposes of this
subparagraph.

            (b)  Sales  of  Securities.  In  connection  with  the  sale  of the
Collateral, Secured Party is authorized, but not obligated, to limit prospective
purchasers  to the extent  deemed  necessary or  desirable  by Secured  Party to
render such sale exempt from the registration requirements of the Securities Act
of 1933, as amended,  and any applicable  state  securities laws, and no sale so
made in good faith by  Secured  Party  shall be deemed  not to be  "commercially
reasonable" because so made.

            (c) Application of Proceeds.  Secured Party shall apply the proceeds
of any sale or other disposition of the Collateral under this Paragraph 7 in the
following  order:  First,  to the  payment of all of its  expenses  incurred  in
retaking,  holding  and  preparing  any of the  Collateral  for sale(s) or other
disposition, in arranging for such sale(s) or other disposition, and in actually
selling  or  disposing  of the same (all of which  are part of the  Obligation);
second, toward repayment of amounts expended by Secured Party under Paragraph 8;
third,  toward payment of the balance of the  Obligation in accordance  with the
Note.  Any surplus  remaining  shall be  delivered  to Pledgors or as a court of
competent jurisdiction may direct.

      8. Other Rights of Secured Party.

            (a) Performance.  In the event Pledgors shall fail to perform any of
their obligations  hereunder with respect to the Collateral,  then Secured Party
may, at its option,  but without being required to do so, take such action which
Pledgors is required,  but has failed or refused,  to take. Any sum which may be
expended or paid by Secured Party under this  subparagraph  (including,  without
limitation,  court costs and attorneys' fees) shall bear interest from the dates
of  expenditure  or payment at the Default Rate (as specified in the Note) until
paid and, together with such interest, shall be a part of the Obligation secured
by the Collateral.

            (b)  Collection.  Upon notice  from  Secured  Party,  each person or
entity  obligated with respect to any of the  Collateral,  whether as an issuer,
account debtor or otherwise (an "Obligor") is hereby  authorized and directed by
Pledgors  to  make  payments  on  any  of  the  Collateral  (including,  without
limitation,  dividends and other  ownership  distributions)  directly to Secured
Party,  regardless  of  whether  Pledgors  were  previously  making  collections
thereon.  Secured  Party  shall have the right in its own name or in the name of
Pledgors  to  compromise  or extend time of payment  with  respect to all or any
portion of the  Collateral for such amounts and upon such terms as Secured Party
may determine; to demand, collect,  receive,  receipt for, sue for, compound and
give  acquittances  for any and all amounts due or to become due with respect to
Collateral;  to take control of cash and other  proceeds of any  Collateral;  to
endorse the name of Pledgors on any notes,  acceptances,  checks,  drafts, money
orders  or other  evidences  of  payment  on  Collateral  that may come into the
possession of Secured Party; to send requests for verification of obligations to
any  Obligor;  and to do all other  acts and things  necessary  to carry out the
intent of this Pledge Agreement. If any Obligor fails or refuses to make payment
on any Collateral when due, Secured Party is authorized, in its sole discretion,
either  in its own name or in the  name of  Pledgors,  to take  such  action  as
Secured  Party shall deem  appropriate  for the  collection of any such amounts.
Regardless of any other provision hereof, however,  Secured Party shall never be
liable for its failure to collect,  or for its failure to exercise  diligence in
the collection of, any amounts owed with respect to Collateral,  nor shall it be
under any duty whatever to anyone  except  Pledgors to account for funds that it
shall  actually  receive  hereunder.  Without  limiting  the  generality  of the
foregoing,  Secured  Party shall have no  responsibility  for  ascertaining  any
maturities,  calls, conversions,  exchanges,  offers, tenders or similar matters
relating to any  Collateral,  or for  informing  Pledgors with respect to any of
such matters  (irrespective  of whether  Secured  Party  actually has, or may be
deemed to have, knowledge thereof).  The receipt of Secured Party to any Obligor
shall be a full and complete release, discharge and acquittance to such Obligor,
to the extent of any amount so paid to Secured Party. The rights granted Secured
Party under this  subparagraph  may be exercised at any time while a Default has
occurred and is continuing.

                                       4
<PAGE>

            (c) Record Ownership of Securities. If a Default has occurred and is
continuing,  Secured Party at any time may have the Collateral registered in its
name, or in the name of its nominee or nominees, as pledgee.

            (d)  Voting  of  Securities.  So long as no  Default  has  occurred,
Pledgors  shall be entitled  to exercise  all voting  rights  pertaining  to the
Collateral.  After the occurrence and during the  continuance of a Default,  the
right to vote the Collateral  shall be vested  exclusively in Secured Party.  To
this end, Pledgors and each of them irrevocably  appoint Secured Party the proxy
and attorney-in-fact of Pledgors,  with full power of substitution,  to vote and
to act with respect to the Collateral,  subject to the  understanding  that such
proxy may not be exercised unless a Default has occurred and is continuing.  The
proxy  herein  granted is coupled with an interest,  is  irrevocable,  and shall
continue until the Obligation has been paid and performed in full.

            (e) Certain Proceeds.  Any and all cash dividends,  equity dividends
or distributions in respect to ownership,  whether in cash or property,  made on
or in respect of the  Collateral,  and any proceeds of the  Collateral,  whether
such   dividends,   distributions,   or  proceeds  result  from  a  subdivision,
combination  or  reclassification  of the  outstanding  membership  interests of
Debtor or which may be  distributable to Pledgors in their capacity as owners of
the Pledged Membership Interests, shall be part of the Collateral hereunder, and
shall be, if  received  by  Pledgors,  held in trust for the  benefit of Secured
Party, and shall forthwith be delivered to Secured Party  (accompanied by proper
instruments of assignment  and/or stock and/or bond powers  executed by Pledgors
in accordance with Secured Party's instructions) to be held subject to the terms
hereof.  Any cash  proceeds  of  Collateral  which come into the  possession  of
Secured Party may, at Secured Party's option,  be applied in whole or in part to
the  Obligation  (to the extent then due), be released in whole or in part to or
on the written  instructions of Pledgors for any general or specific purpose, or
be retained in whole or in part by Secured Party as additional Collateral.

      9. Miscellaneous.

            (a) Term.  Upon full and final payment of the Obligation and without
Secured  Party having  exercised  its rights under this Pledge  Agreement,  this
Pledge  Agreement  shall  terminate;  provided  that  no  Obligor  on any of the
Collateral  shall be obligated to inquire as to the  termination  of this Pledge
Agreement,  but shall be fully  protected in making payment  directly to Secured
Party,  which payment shall be promptly paid over to Pledgors after  termination
of this Pledge Agreement.

            (b) Notices.  Any notice,  demand or document  which either party is
required or may desire to give hereunder  shall be in writing and, except to the
extent  provided  in the other  provisions  of this Pledge  Agreement,  given by
messenger,   telecopy  or  other  electronic  transmission,   or  United  States
registered  or  certified  mail,  postage  prepaid,  return  receipt  requested,
addressed  to such party at its address and telecopy  number shown below,  or at
such other  address as either party shall have  furnished to the other by notice

of the following  events:  (i) the taking or accepting of any other  security or
assurance  for  any or  all of the  Obligation;  (ii)  any  release,  surrender,
exchange,  subordination  or loss  of any  security  or  assurance  at any  time
existing in connection with any or all of the Obligation; (iii) the modification
of,  amendment to, or waiver of compliance  with,  any terms of the Note without
the  consent of  Pledgors,  except as  required  therein;  (iv) the  insolvency,
bankruptcy  or lack of  corporate or trust power of any party at any time liable
for  the  payment  of any or all of the  Obligation,  whether  now  existing  or
hereafter occurring; (v) any renewal,  extension or rearrangement of the payment

Pledgors, or any adjustment,  indulgence,  forbearance or compromise that may be
granted or given by Secured Party to Debtor; (vi) any neglect,  delay, omission,
failure  or  refusal  of  Secured  Party  to take or  prosecute  any  action  in
connection with the Note;  (vii) any failure of Secured Party to notify Pledgors
(A) of any  assignment of the  Obligation or any part thereof,  (B) of any other
action taken or refrained  from being taken by Secured Party  against  Debtor or
(C) any new  agreement  between  Secured Party and Debtor,  it being  understood
that,  except as  expressly  required  by the Note,  Secured  Party shall not be
required  to give  Pledgors  any  notice  of any kind  under  any  circumstances
whatsoever  with respect to or in  connection  with the  Obligation,  including,
without  limitation,  notice  of  acceptance  of this  Pledge  Agreement  or any
Collateral  ever  delivered  to or for the  account of Secured  Party under this
Pledge Agreement;  (viii) the illegality,  invalidity or unenforceability of all
or any part of the  Obligation  against  Debtor  by  reason of the fact that the
Obligation,  or the interest paid or payable with respect  thereto,  exceeds the
amount  permitted  by law;  or (ix) if any payment by any party  obligated  with
respect thereto is held to constitute a preference  under applicable laws or for
any other  reason  Secured  Party is required to refund such  payment or pay the
amount thereof to someone else.

                                       6
<PAGE>

            (f)  Waivers.  Debtor  and  Pledgors  waive (i) any Right to require
Secured Party to proceed  against any other person,  to exhaust  Secured Party's
rights in the  Collateral,  or to pursue any other right which Secured Party may
have; (ii) with respect to the  Obligation,  presentment and demand for payment,
protest, notice of protest and nonpayment, notice of acceleration, and notice of
the  intention to  accelerate;  and (iii) all rights of marshaling in respect of
any and all of the Collateral.

            (g) Financing Statement. Secured Party shall be entitled at any time
to file this Pledge Agreement,  or a carbon,  photographic or other reproduction
of this Pledge Agreement,  as a financing statement,  but the failure of Secured
Party  to do so  shall  not  impair  the  validity  or  enforceability  of  this
Agreement.

            (h)  Amendments.  This  Pledge  Agreement  may only be  amended by a
writing executed by Pledgors, Debtor and Secured Party.

            (i) Multiple Counterparts.  This Pledge Agreement may be executed in
any number of identical  counterparts with the same effect as if all signatories
had signed the same document. In making proof of this Pledge Agreement, it shall
not be  necessary  to produce or  account  for more than one set of  counterpart
signatures.  Delivery of the executed signature pages by facsimile  transmission
shall  constitute  effective  and binding  execution and delivery of this Pledge
Agreement.

            (j) Parties  Bound.  This Pledge  Agreement  shall be binding on and
inure  to  the  benefit  of the  parties  hereto  and  their  respective  heirs,
successors, permitted assigns and other legal representatives. Delivery or other
accounting of the  Collateral to Pledgors shall  discharge  Secured Party of all
liability therefor.

            (k)  Assignment.  Pledgors  may not assign any  rights,  duties,  or
obligations  under this Pledge  Agreement  without Secured Party's prior written
consent,  which consent shall not be unreasonably  withheld.  In the event of an
assignment  of all or part of the  Obligation,  the Security  Interest and other
rights and benefits under this Pledge Agreement, to the extent applicable to the
part of the Obligation so assigned,  may be transferred with the Obligation,  as
the case may be.

            (l) Severability.  If any provision of this Pledge Agreement is held
to be  illegal,  invalid or  unenforceable  under  present or future  laws,  the
legality, validity and enforceability of the remaining provisions of this Pledge
Agreement  shall not be affected  thereby,  and this Pledge  Agreement  shall be
liberally  construed  so as to carry out the  intent of the  parties  to it. Any
waiver  contained  in this Pledge  Agreement  is subject to the  overriding  and
controlling  rule that it shall be effective  only if and to the extent that (a)
it is not prohibited by applicable  law and (b) applicable law neither  provides
for nor allows any material  sanctions to be imposed  against  Secured Party for
having bargained for and obtained it.

      SHARE EXCHANGE AND REORGANIZATION  AGREEMENT,  dated as of August 25, 2004
(the "Agreement"),  between GREAT EXPECTATIONS AND ASSOCIATES,  INC., a Colorado
corporation ("GXPT"); and ADVAXIS, INC., a Delaware corporation ("Advaxis"), and
the SHAREHOLDERS OF ADVAXIS set forth on Schedule A hereto,  which  shareholders
constitute  all of the holders of capital stock of Advaxis as of the date hereof
and as of the Closing (as defined below) (the "Advaxis Shareholders").

                                  INTRODUCTION

      GXPT  desires to acquire (i) all of the issued and  outstanding  shares of
Common Stock of Advaxis (the  "Advaxis  Common  Stock"),  and Series A Preferred
Stock of Advaxis (the  "Advaxis  Series A Preferred  Stock;'  together  with the
Advaxis Common Stock,  the "Advaxis Capital Stock") in exchange for an aggregate
of 15,597,723  shares (the  "Purchase  Shares") of authorized,  but  theretofore
unissued,  shares of common  stock,  no par  value,  of GXPT (the  "GXPT  Common
Stock"),  (ii) all of the issued and  outstanding  warrants to purchase  Advaxis
Capital  Stock (the  "Advaxis  Warrants"),  in exchange for Warrants to purchase
584,885 shares of GXPT Common Stock (the "GXPT Warrants"),  and (iii) all of the
issued and outstanding  options to purchase  Advaxis Capital Stock (the "Advaxis
Options") in exchange for an  aggregate  of 2,381,525  options to purchase  GXPT
Common  Stock (the "GXPT  Options");  representing  96.25% of the fully  diluted
outstanding  GXPT Common Stock after  giving  effect to such  issuances  and the
issuance of shares of GXPT Common Stock  referred to in Section  3.01(p)  below,
all as more  fully set forth on  Schedule  B hereto.  The  Advaxis  Shareholders
desire to exchange  their  beneficially  owned shares of Advaxis  Capital  Stock
solely for shares of GXPT Common Stock at a ratio of  352.1823361  as more fully
set forth on Schedule B hereto.

      Prior to the date hereof,  the  respective  boards of directors of each of
GXPT and Advaxis have, and the Advaxis Shareholders and the shareholders of GXPT
have,  approved and adopted this  Agreement  and it is the intent of the parties
hereto that the transactions  contemplated hereby be structured so as to qualify
as a tax-free  exchange under Subchapter C of the Internal Revenue Code of 1986,
as  amended  (the  "Code"),  and  the  provisions  of  this  Agreement  will  be
interpreted in a manner consistent with this intent.

      There  shall be an offering  to sell up to 280 units (the  "Units"),  each
Unit  consisting  of 87,108 shares of GXPT Common Stock and Warrants to purchase
87,108  shares of GXPT Common  Stock for an  aggregate  purchase  price of up to
$7,000,000 (the  "Offering").  In connection with the Offering all of the issued
and outstanding promissory notes of Advaxis which are convertible into shares of
Advaxis capital stock (the "Advaxis  Notes") shall be exchanged for Units on the
same terms as in the  Offering.  As of the date hereof the  aggregate  principal
amount of the Advaxis Notes is $494,729.
<PAGE>

      After giving effect to (a) the acquisition of the Advaxis Capital Stock in
exchange  for the  Purchase  Shares,  (b) the  issuance of shares of GXPT Common
Stock referred to in Section 3.01(p) below, and (c) the exchanges of the Advaxis
Warrants and Advaxis  Options for GXPT Warrants and GXPT Options (but not giving
effect to the issuance  and/or  conversion  of the Advaxis  Notes,  the Units or
shares of GXPT Common  Stock or  Warrants  issuable  to  placement  agents or to
consultants  in  connection  with  the  Offering)  there  shall  be  outstanding
20,069,333  shares of common stock of GXPT, on a fully diluted basis. Such fully
diluted capitalization table is set forth on Schedule B hereto.

      Upon the  signing of this  Agreement  by all  parties  to this  Agreement,
Advaxis shall advance to GXPT a nonrefundable payment of $7,500 by wire transfer
or by  certified  check.  The closing of the  transaction  contemplated  by this
Agreement (the "Closing")  shall occur when $1,500,000 has been placed in escrow
in connection with the Offering;  it being  understood  however that the date of
the Closing must occur on or prior to forty-five  (45) days from the date hereof
(the  "Initial  Closing  Date").  If Advaxis  advances  to GXPT a  nonrefundable
payment of $15,000 on or prior to the Initial Closing Date, then the date of the
Closing shall be extended for an  additional  forty-five  (45) day period.  Such
advances shall be offset against the amount Advaxis shall pay to GXPT at Closing
as set forth in Section 1.03(e).

      NOW,   THEREFORE,   in   consideration   of  the   premises   and   mutual
representations,  warranties and covenants herein contained,  the parties hereby
agree as follows:

                                    ARTICLE I

            FOR SALE, SOLD, OR OTHERWISE  DISPOSED OF, EXCEPT IN COMPLIANCE WITH
            THE REGISTRATION  PROVISIONS OF SUCH ACT OR PURSUANT TO AN EXEMPTION
            FROM SUCH REGISTRATION  PROVISIONS,  THE AVAILABILITY OF WHICH IS TO
            BE ESTABLISHED TO THE SATISFACTION OF THE COMPANY.

Reitler Brown & Rosenblatt LLC ("Reitler Brown") on the date that $1,500,000 has

other time and place to be mutually agreed upon by the parties hereto;  provided
that such date will occur by the Initial Closing Date unless extended by Advaxis
in the  manner  set  forth  in the  Introduction,  and  will be  subject  to the

                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

      SECTION  2.01   REPRESENTATIONS   AND  WARRANTIES  OF  GXPT.  GXPT  hereby
represents   and  warrants  to,  and  agrees  with,   Advaxis  and  the  Advaxis
Shareholders as follows:

      (a) Organization and  Qualification.  Other than as set forth in Section A
of the disclosure  letter,  of even date herewith,  from GXPT to Advaxis and the
Advaxis  Shareholders  (the "GXPT  Disclosure  Letter"),  GXPT does not have any
subsidiaries  or  affiliated  corporations  and does not own any interest in any
other  enterprise  (whether or not such enterprise is a corporation).  GXPT is a
corporation  duly organized,  validly  existing,  and in good standing under the
laws of the State of Colorado,  with all requisite power and authority,  and all
necessary consents,  authorizations,  approvals, orders, licenses, certificates,
and permits of and from, and declarations and filings with, all federal,  state,
local, and other governmental authorities and all courts and other tribunals, to
own,  lease,  license,  and use its  properties  and  assets and to carry on the
businesses  in  which  it  is  now  engaged  and  the  businesses  in  which  it
contemplates  engaging.  Other  than  as set  forth  in  Section  A of the  GXPT
Disclosure Letter, GXPT is duly qualified to transact the businesses in which it
is  engaged  and  is  in  good  standing  as  a  foreign  corporation  in  every
jurisdiction in which its ownership,  leasing,  licensing, or use of property or
assets or the conduct of its businesses makes such qualification necessary.

                                       4
<PAGE>

      (b)  Capitalization.  Immediately  prior to the  Closing,  the  authorized
capital stock of GXPT consists of  500,000,000  shares of GXPT Common Stock,  of
which 150,520,000  shares are outstanding.  Prior to Closing,  a majority of the
GXPT  shareholders  shall  approve  and caused to become  effective  the charter
amendments  contemplated by Section 3.01 hereof. Each of such outstanding shares
of GXPT Common Stock is validly  authorized,  validly  issued,  fully paid,  and
nonassessable,  has not been issued and is not owned or held in violation of any
preemptive or similar right of  stockholders.  There is no commitment,  plan, or
arrangement to issue, and no outstanding option, warrant, or other right calling
for the issuance of, any share of capital stock of GXPT or any security or other
instrument  convertible into, exercisable for, or exchangeable for capital stock
of GXPT other than the  Offering.  There is  outstanding  no  security  or other
instrument  convertible  into, or exchangeable or exercisable for, capital stock
of GXPT.

      (c) Financial  Condition.  GXPT has filed with the Securities and Exchange

the following:  audited  balance sheets of GXPT as of October 31, 2002 and 2003;
unaudited  balance  sheets  of GXPT as of  April  30,  2003  and  2004;  audited
statements of income, statements of stockholders' equity, and statements of cash
flows of GXPT for the years ended  October 31, 2002 and 2003;  and the unaudited
statements of income, statements of stockholders' equity, and statements of cash
flows of GXPT for the six  months  ended  April  30,  2003 and  2004.  Each such
balance sheet shall present fairly the financial condition, assets, liabilities,
and stockholders'  equity of GXPT as of its respective date; each such statement
of income and statement of stockholders' equity shall present fairly the results
of operations of GXPT for the period indicated;  and each such statement of cash
flows shall present fairly the  information  purported to be shown therein.  The
financial statements referred to in this Section 2.01(c) will have been prepared
in accordance with generally accepted accounting principles in the United States
("GAAP")  consistently  applied  throughout the periods involved and shall be in
accordance with the books and records of GXPT. The financial statements referred
to in this Section 2.01(c) contain all certifications and statements required by
the SEC's  Order,  dated June 27,  2002,  pursuant  to Section  21(a)(1)  of the
Exchange Act (File No. 4-460),  Rule 13a-14 or 15d-14 under the Exchange Act, or
18 U.S.C.  Section 1350 (Sections 302 and 906 of the Sarbanes-Oxley Act of 2002)
with respect to the report relating thereto.  The financial  statements referred
to in this  Section  2.01(c)  comply as to form in all  material  respects  with
applicable accounting  requirements and with the published rules and regulations
of the SEC with respect  thereto,  have been prepared in  accordance  with GAAP,
applied on a  consistent  basis  during the periods  involved  (except as may be
indicated  in  the  notes  thereto  or,  in  the  case  of  unaudited  financial
statements,  as  permitted by the rules and  regulations  of the SEC) and fairly
present, subject in the case of the unaudited financial statements, to customary
year end  audit  adjustments,  the  financial  position  of GXPT as at the dates
thereof and the results of its operations and cash flows. Since April 30, 2004:

                  (i) There has at no time been a material adverse change in the
            financial condition, results of operations,  businesses, properties,
            assets, liabilities, or future prospects of GXPT.

                                       5
<PAGE>

                  (ii) GXPT has not authorized,  declared, paid, or effected any
            dividend  or  liquidating  or other  distribution  in respect of its
            capital  stock or any direct or indirect  redemption,  purchase,  or
            other acquisition of any stock of GXPT.

                  (iii)  The   operations  and  businesses  of  GXPT  have  been
            conducted in all respects  only in the  ordinary  course,  except as
            described in filings made and to be made by GXPT to the SEC..

There is no fact  known to GXPT  which  materially  adversely  affects or in the
future (as far as GXPT can reasonably  foresee) may materially  adversely affect
the financial condition, results of operations,  businesses, properties, assets,
liabilities, or future prospects of GXPT; provided, however, that GXPT expresses
no opinion as to political or economic  matters of general  applicability.  GXPT
has made known,  or caused to be made known,  to the accountants or auditors who
have prepared,  reviewed, or audited the aforementioned  consolidated  financial
statements  all  material  facts  and  circumstances   which  could  affect  the
preparation, presentation, accuracy, or completeness thereof.

      (d) Tax and Other  Liabilities.  GXPT does not have any material liability
of any nature, accrued or contingent, including, without limitation, liabilities
for  federal,  state,  local,  or foreign  taxes and  penalties,  interest,  and
additions to tax ("Taxes"),  and  liabilities  to customers or suppliers,  other
than the following:

                  (i)  Liabilities for which full provision has been made on the
            balance sheet and the notes thereto (the "Last GXPT Balance  Sheet")
            as of April 30, 2004,  (the "Last GXPT Balance Sheet Date") referred
            to in Section 2.01(c); and

                  (ii) Other  liabilities  arising  since the Last GXPT  Balance
            Sheet Date and prior to Closing in the  ordinary  course of business
            (which  shall not include  liabilities  to  customers  on account of
            defective  products or services) which are not inconsistent with the
            representations  and  warranties  of GXPT or any other  provision of
            this Agreement.

Without  limiting  the  generality  of  the  foregoing,  the  amounts  set up as
provisions  for Taxes on the Last GXPT  Balance  Sheet  are  sufficient  for all
accrued and unpaid Taxes of GXPT,  whether or not due and payable and whether or
not  disputed,  under tax laws, as in effect on the Last GXPT Balance Sheet Date
or now in effect,  for the period ended on such date and for all fiscal  periods
prior thereto.  The execution,  delivery,  and  performance of this Agreement by
GXPT will not cause any Taxes to be payable  (other than those that may possibly
be payable by the Advaxis  Shareholders as a result of the contribution of their
shares  of  Advaxis  Capital  Stock  to  GXPT) or cause  any  lien,  charge,  or
encumbrance  to secure any Taxes to be created  either  immediately  or upon the
nonpayment  of any Taxes other than on the  properties  or assets of the Advaxis
Shareholders.  GXPT has filed all federal, state, local, and foreign tax returns
required to be filed by it; has delivered to the Advaxis Shareholders a true and
correct copy of each such return which was filed since  incorporation;  has paid
(or has  established  on the Last GXPT  Balance  Sheet a reserve for) all Taxes,
assessments,  and other  governmental  charges  payable or  remittable  by it or
levied upon it or its properties,  assets,  income,  or franchises which are due
and payable;  and has delivered to the Advaxis  Shareholders  a true and correct
copy of any report as to  adjustments  received by it from any taxing  authority
since incorporation and a statement as to any litigation,  governmental or other
proceeding (formal or informal),  or investigation  pending,  threatened,  or in
prospect with respect to any such report or the subject matter of such report.

                                       6

      (e)  Litigation  and Claims.  Except as described in Section E of the GXPT
Disclosure Letter, there is no litigation,  arbitration,  claim, governmental or
other proceeding (formal or informal),  or investigation pending or, to the best
of GXPT's knowledge,  threatened, or in prospect (or any basis therefor known to
GXPT) with respect to GXPT or any of its businesses, properties, or assets. GXPT
is not a "union shop" and is not a party to any collective  bargaining agreement
or similar labor arrangement.  GXPT is not affected by any present or threatened
strike or other labor  disturbance  nor to the  knowledge of GXPT,  is any union
attempting  to represent any employee of GXPT as  collective  bargaining  agent.
GXPT is not in  violation  of, or in default  with  respect  to, any law,  rule,
regulation,  order,  judgment, or decree which violation or default would have a
material  adverse  effect on GXPT;  nor is GXPT  required  to take any action in
order to avoid such violation or default.

      (f) Properties.

            (i) GXPT owns no real property.  GXPT has good title to all personal
properties  and  assets  used in its  businesses  or owned  by it and has  valid
leasehold  interests  and  licenses  in and with  respect  to all real and other
properties  and assets as are held  pursuant to leases or licenses  described in
Section B or C of the GXPT Disclosure Letter and used in its business,  free and
clear  of all  liens,  mortgages,  security  interests,  pledges,  charges,  and
encumbrances  (except  such as are  listed in  Section F of the GXPT  Disclosure
Letter).

            (ii) Set forth in Section F of the GXPT Disclosure  Letter is a true
and complete list of all tangible  properties and assets owned by GXPT or leased
or  licensed  by GXPT  from or to a third  party  (including  inventory  but not
including  Intangibles  (as  hereinafter  defined)),  and with  respect  to such
properties  and assets  leased or licensed by GXPT from or to a third  party,  a
description  of such lease or license,  including  the term interest and amounts
paid GXPT under such lease or license. All such properties and assets (including
Intangibles)  owned by GXPT are reflected on the Last GXPT Balance Sheet (except
for acquisitions subsequent to the Last GXPT Balance Sheet Date and prior to the
Closing Date, which are set forth in Section F of the GXPT Disclosure  Letter or
are approved in writing by Advaxis). All tangible properties and assets owned by
GXPT or leased  or  licensed  by GXPT  from or to a third  party are in good and
usable  condition  (reasonable  wear  and tear  which  is not such as to  affect
adversely the operation of the businesses of GXPT excepted). All such leases and
licenses to which GXPT is a party are in full force and effect.

            (iii) To the best of GXPT's  knowledge,  no real property  leased or
licensed  by GXPT from or to a third party lies in an area which is, or will be,
subject to zoning, use, or building code restrictions which would prohibit, and,
to the best of GXPT's  knowledge,  no state of facts  relating to the actions or
inaction  of  another  person  or entity or his or its  ownership,  leasing,  or
licensing  of any real or  personal  property  exists or will exist  which would
prevent, the continued effective  ownership,  leasing, or licensing of such real
property in the  businesses  in which GXPT is now engaged or the  businesses  in
which it contemplates engaging.

                                       7
<PAGE>

            (iv)  The  properties   and  assets   (including   Intangibles   (as
hereinafter defined)) owned by GXPT (other than those leased or licensed by GXPT
to a third  party) or leased or licensed  by GXPT from a third party  constitute
all such  properties and assets which are necessary to the businesses of GXPT as
presently conducted.

            (v) GXPT has not caused or permitted its businesses  properties,  or
assets to be used to generate,  manufacture,  refine,  transport,  treat, store,
handle,  dispose of, transfer,  produce,  or process any Hazardous Substance (as
such term is defined in this Section  2.01(f)(v))  except in compliance with all
applicable laws, rules, regulations, orders, judgments, and decrees, and has not
caused or  permitted  the  Release  (as such  term is  defined  in this  Section
2.01(f)(v))  of any  Hazardous  Substance  on or off the site of any property of
GXPT. The term "Hazardous  Substance" shall mean any hazardous waste, as defined
by 42 U.S.C.  ss.6903(5),  any  hazardous  substance,  as  defined  by 42 U.S.C.
ss.9601(14),  any pollutant or contaminant, as defined by 42 U.S.C. ss.9601(33),
and all toxic  substances,  hazardous  materials,  or other chemical  substances
regulated by any other law, rule, or regulation.  The term "Release"  shall have
the meaning set forth in 42 U.S.C. ss.9601(22).

      (g)  Contracts  and Other  Instruments.  Section G of the GXPT  Disclosure
Letter contains a true and correct  statement of the information  required to be
contained therein regarding material contracts, agreements, instruments, leases,
licenses,  arrangements,  or  understandings  with  respect  to  GXPT.  GXPT has
furnished to the Advaxis  Shareholders (i) the certificate of incorporation  (or
other  charter  document)  and by-laws of GXPT and all  amendments  thereto,  as
presently in effect, and (ii) the following:  (A) true and correct copies of all
material contracts,  agreements, and instruments referred to in Section G of the
GXPT Disclosure  Letter;  (B) true and correct copies of all material leases and
licenses referred to in Section G of the GXPT Disclosure Letter hereto;  and (C)
true and correct  written  descriptions  of all material  supply,  distribution,
agency,  financing,  or other  arrangements  or  understandings  referred  to in
Section  G of the  GXPT  Disclosure  Letter.  To the best of  GXPT's  knowledge,
neither GXPT nor (to the knowledge of GXPT) any other party to any such material
contract,  agreement,  instrument,  lease,  or  license is now or expects in the
future to be in  violation or breach of, or in default with respect to complying
with, any term thereof, and each such material contract, agreement,  instrument,
lease,  or license is in full force and is (to the best of GXPT's  knowledge  in
the case of third  parties)  the legal,  valid,  and binding  obligation  of the
parties  thereto and (subject to applicable  bankruptcy,  insolvency,  and other
laws affecting the enforceability of creditors' rights generally) is enforceable
as to them in accordance with its respective  terms.  Each such material supply,
distribution,  agency,  financing,  or other  arrangement or  understanding is a
valid and continuing  arrangement or  understanding;  neither GXPT nor any other
party to any such arrangement or  understanding  has given notice of termination
or taken any action  inconsistent  with the  continuance of such  arrangement or
understanding;  and the execution,  delivery,  and performance of this Agreement
will not prejudice any such arrangement or understanding in any way. GXPT enjoys
peaceful and undisturbed possession under all material leases and licenses under
which it is  operating.  GXPT is not  party  to,  or  bound  by,  any  contract,
agreement, instrument, lease, license, arrangement, or understanding, or subject
to any charter or other restriction, which has had or (to the knowledge of GXPT)

                                       8
<PAGE>

may in the future have a material  adverse  effect on the  financial  condition,
results of operations,  businesses,  properties,  assets, liabilities, or future
prospects  of GXPT.  GXPT has not engaged  within the last five years in, is not
engaging in, and does not intend to engage in any transaction  with, and has not
had within the last five years,  does not now have,  and does not intend to have
any material contract,  agreement,  instrument,  lease, license, arrangement, or
understanding with, any stockholder of GXPT, any director,  officer, or employee
of GXPT  (except  for  employment  agreements  listed  in  Section G of the GXPT
Disclosure  Letter and employment  and  compensation  arrangements  described in
Section H of the GXPT  Disclosure  Letter),  any  relative or  affiliate  of any
stockholder of GXPT or of any such director,  officer, or employee, or any other
corporation  or enterprise in which any  stockholder of GXPT, any such director,
officer, or employee, or any such relative or affiliate then had or now has a 5%
or  greater  equity or voting or other  substantial  interest,  other than those
listed and so specified in Section G of the GXPT  Disclosure  Letter.  The stock
ledgers and stock  transfer  books  relating to all  issuances  and transfers of
stock by GXPT and the minute  book  records of GXPT and all  proceedings  of the
stockholders  and the Board of Directors  and  committees  thereof of GXPT since
their  respective  incorporations  made  available to counsel to Advaxis and the
Advaxis Shareholders are the original stock ledgers and stock transfer books and
minute book records of GXPT or exact copies thereof. GXPT is not in violation or
breach  of, or in  default  with  respect  to,  any term of its  certificate  of
incorporation (or other charter document) or by-laws.

      (h) Employees.

            (i)  GXPT  does  not  have,   or   contribute   to,   any   pension,
profit-sharing,  option,  other  incentive  plan,  or any other type of Employee
Benefit  Plan (as  defined in Section  3(3) of the  Employee  Retirement  Income
Security Act of 1974, as amended  ("ERISA")),  nor does GXPT have any obligation
to or customary arrangement with employees for bonuses,  incentive compensation,
vacations,  severance  pay,  sick pay,  sick leave,  insurance,  service  award,
relocation,  disability,  tuition  refund,  or other  benefits,  whether oral or
written,  except as set forth in Section H of the GXPT Disclosure  Letter.  GXPT
has  furnished  to Advaxis  and the Advaxis  Shareholders:  (A) true and correct
copies of all documents evidencing plans, obligations,  or arrangements referred
to in  Section H of the GXPT  Disclosure  Letter  (or true and  correct  written
summaries,  so initialed,  of such plans,  obligations,  or  arrangements to the
extent not evidenced by documents) and true and correct copies, so initialed, of
all  documents  evidencing  trusts,  summary  plan  descriptions,  and any other
summaries or  descriptions  relating to any such plans;  (B) the two most recent
annual reports (Form 5500's),  if any,  including all schedules  thereto and the
most recent  annual and periodic  accounting of related plan assets with respect
to each Employee Benefit Plan; (C) the two most recent actuarial valuations with
respect to each Pension  Plan (as defined in Section  3(2) of ERISA)  subject to
Title IV of ERISA;  and (D) the most recent  determination  letter issued by the
Internal Revenue Service with respect to each Pension Plan.

            (ii) If any Employee  Benefit Plan of GXPT were to be  terminated on
the day prior to Closing Date, (A) no liability under Title IV of ERISA would be
incurred  by GXPT or Advaxis and (B) all  Accrued  Benefits  (as defined in this
Section  2.01(h)(ii))  to such day prior to the  Closing  Date  (whether  or not
vested) would be fully funded in accordance  with the  assumptions  contained in
the  regulations  of the Pension  Benefit  Guaranty  Corporation  governing  the
funding of terminated  defined  benefit  plans.  For purposes  hereof,  "Accrued
Benefits" shall include the value of disability, pre-retirement, death benefits,

                                       9
<PAGE>

and all supplements,  subsidized, ancillary, and optional forms of benefits. All
Accrued Liabilities (for contributions or otherwise) (as defined in this Section
2.01(h)(ii))  of GXPT as of the Closing Date to each  Employee  Benefit Plan and
with respect to each obligation to, or customary arrangement with, employees for
bonuses, incentive compensation, vacations, severance pay, sick pay, sick leave,
insurance,  service award,  relocation,  disability,  tuition  refund,  or other
benefits,  whether  oral or  written,  have been paid or accrued for all periods
ending prior to the Closing Date and no payment to any Employee  Benefit Plan or
with respect to any such  obligation or arrangement  since the Last GXPT Balance
Sheet Date has been  disproportionately  large compared to prior  payments.  For
purposes hereof,  "Accrued Liabilities" shall include a pro rata contribution to
each  Employee  Benefit  Plan  or  with  respect  to  each  such  obligation  or
arrangement  for that  portion of a plan year or other  applicable  period which
commences  prior to, and ends after,  the Closing Date, and Accrued  Liabilities
for any portion of a plan year or other applicable period shall be determined by
multiplying the liability for the entire such year or period by a fraction,  the
numerator of which is the number of days preceding the Closing Date in such year
or period  and the  denominator  of which is the  number of days in such year or
period, as the case may be.

            (iii) There has been no violation of the  reporting  and  disclosure
requirements imposed either under ERISA or the Code for which a penalty has been
or may be imposed with respect to any Employee  Benefit Plan of GXPT.  There has
been no breach of fiduciary duty or responsibility  with respect to any Employee
Benefit Plan of GXPT. No Employee  Benefit Plan of GXPT or related trust has any
liability of any nature,  accrued or contingent,  including  without  limitation
liabilities for Taxes,  other than for routine payments to be made in due course
to participants and beneficiaries,  except as set forth in Section H of the GXPT
Disclosure Letter. GXPT does not have any formal plan or commitment,  whether or
not legally  binding,  to create any additional or modify any existing  Employee
Benefit  Plan  or  benefit  obligation  or  arrangement   described  in  Section
2.01(h)(i)).  Each  Employee  Benefit  Plan of GXPT which is a group health plan
within the meaning of Section  5000(b)(1) of the Code is and has been maintained
in full  compliance  with the  applicable  requirements  of Section 4980B of the
Code. Other than the health care  continuation  requirements of Section 4980B of
the Code, GXPT does not have any obligation to provide  post-retirement  medical
benefits or life insurance coverage or any deferred compensation benefits to any
present  or  former  employees.  There  is no  litigation,  arbitration,  claim,
governmental or other proceeding (formal or informal), or investigation pending,
threatened,  or (to the best of  GXPT's  knowledge)  in  prospect  (or any basis
therefor  known to GXPT) with  respect to any  Employee  Benefit Plan of GXPT or
related trust or with respect to any  fiduciary,  administrator,  or sponsor (in
its capacity as such) of any Employee  Benefit Plan. No Employee Benefit Plan of
GXPT or related trust and no such  obligation or arrangement is in violation of,
or in default with respect to, any law, rule, regulation, order, judgment, which
violation or default would have a material  adverse effect thereon or decree nor
is GXPT,  any Employee  Benefit Plan of GXPT, or any related  trust  required to
take any action in order to avoid any such  violation  or default.  No event has
occurred,  or is (to the best of GXPT's knowledge) threatened or about to occur,
which would constitute a prohibited transaction under Section 406 of ERISA.

            (iv) Each Pension Plan maintained for the employees of GXPT has been
qualified, from its inception,  under Section 401(a) of the Code and any related
trust has been an exempt  trust for such period  under  Section 501 of the Code.

                                       10
<PAGE>

Each Pension Plan has been  operated in  accordance  with its terms.  No Pension
Plan which is subject to Title IV of ERISA has an  accumulated or waived funding
deficiency  within the meaning of Section 412 of the Code. No  investigation  or
review by the Internal Revenue Service is currently pending or (to the knowledge
of GXPT) is contemplated  in which the Internal  Revenue Service has asserted or
may assert that any Pension Plan is not qualified  under  Section  401(a) of the
Code or that any  related  trust is not exempt  under  Section  501 of the Code.
Neither  GXPT,  nor any  organization  to which  GXPT is a  successor  or parent
corporation, within the meaning of Section 4069(b) of ERISA, has divested itself
of any entity  maintaining  or with an  obligation  to contribute to any Pension
Plan  which had an  "amount  of  unfunded  benefit  liabilities,"  as defined in
Section 4001(a)(18) of ERISA, at the time of such divestiture.  No assessment of
any federal  taxes with  respect to any  Employee  Benefit Plan of GXPT has been
made or (to the knowledge of GXPT) is contemplated  against GXPT, or any related
trust of any Pension Plan of GXPT,  and nothing has occurred  which would result
in the  assessment  of  unrelated  business  taxable  income under the Code with
respect to any Employee Benefit Plan of GXPT. Form 5500's have been timely filed
with  respect to all  Pension  Plans of GXPT.  No event has  occurred or (to the
knowledge  of GXPT) is  threatened  or about to occur which would  constitute  a
reportable  event within the meaning of Section  4043(b) of ERISA.  No notice of
termination has been filed by the plan administrator pursuant to Section 4041 of
ERISA or issued by the Pension Benefit Guaranty  Corporation pursuant to Section
4042 of ERISA with respect to any Pension Plan of GXPT.

            (v) GXPT does not currently  contribute to, and has not  effectuated
either a complete or partial  withdrawal  from, any  multiemployer  Pension Plan
within the meaning of Section 3(37) of ERISA.

            (vi)  Section H of the GXPT  Disclosure  Letter  contains a true and
correct  statement  of the  names,  relationship  with  GXPT,  present  rates of
compensation  (whether  in the form of salary,  bonuses,  commissions,  or other
supplemental  compensation now or hereafter payable), and aggregate compensation
for the fiscal  years ended  December  31,  2002 and 2003 of (A) each  director,
officer,  or other employee of GXPT whose aggregate  compensation for the fiscal
years ended  December 31, 2002 and 2003  exceeded  US$25,000 or whose  aggregate
compensation presently exceeds the rate of US$25,000 per annum and (B) all sales
agents,  dealers, or distributors of GXPT. Since December 31, 2003, GXPT has not
changed the rate of compensation of any of its directors,  officers,  employees,
agents,  dealers, or distributors,  nor has any Employee Benefit Plan or program
of GXPT been instituted or amended to increase benefits thereunder.  There is no
contract,  agreement,  plan,  arrangement,  or understanding covering any person
that, individually or collectively, could give rise to the payment of any amount
that would not be deductible by GXPT by reason of Section 280G of the Code.

            (vii) GXPT has not extended or maintained  credit,  arranged for the
extension  of  credit,  or  renewed an  extension  of  credit,  in the form of a
personal  loan  to or for any  director  or  executive  officer  (or  equivalent
thereof) thereof.

      (i) Patents, Trademarks, Et Cetera. GXPT does not own or have pending, and
is not licensed or otherwise  permitted  to use,  any  material  patent,  patent
application,   trademark,   trademark  application,   service  mark,  copyright,
copyright application,  franchise,  trade secret, computer program (in object or
source code or otherwise),  or other intangible property or asset (collectively,
"Intangibles"),  other than as  described  in  Section I of the GXPT  Disclosure
Letter.  Each  Intangible  set forth in such  Section  I of the GXPT  Disclosure
Letter is  validly  issued  and is  currently  in force and  uncontested  in all
jurisdictions  in which it is used or in which such use is  contemplated by GXPT
and may  reasonably be  contemplated  by GXPT after the  effective  date of this
Agreement  and the  closing of the  Offering.  Section I of the GXPT  Disclosure
Letter  contains a true and correct  listing of: (i) all  Intangibles  which are
owned  (either  in whole or in  part),  used by,  or  licensed  to GXPT or which
otherwise  relate to the  businesses  of GXPT,  and a  description  of each such
Intangible  which  identifies  its owner,  registrant,  or  applicant;  (ii) all
contracts,  agreements,  instruments, leases, and licenses and identification of
all parties thereto under which GXPT owns or uses any Intangible (whether or not
under  license from third  parties),  together  with the  identification  of the
owner,  registrant,  or applicant of each such Intangible;  (iii) all contracts,
agreements,  instruments, leases, and licenses and identification of all parties
thereto  under  which  GXPT  grants  the right to use any  Intangible;  (iv) all
validity,  infringement,  right-to-use,  or other  opinions of counsel  (whether
in-house or outside) which concern the validity, infringement, or enforceability
of any  Intangible  owned or controlled by a party other than GXPT which relates
to the businesses, properties, or assets of GXPT. Except as specified in Section
I of the GXPT Disclosure  Letter, to the knowledge of GXPT: (v) GXPT is the sole
and exclusive owner or licensee of, and (other than those  exclusively  licensed
by  GXPT to a third  party)  has the  right  to use,  all  Intangibles;  (vi) no
Intangible  is subject  to any order,  judgment,  decree,  contract,  agreement,
instrument,  lease, or license  restricting the scope of the use thereof;  (vii)
during the last five years,  GXPT has not been charged with, and has not charged
others with, unfair  competition or infringement of any Intangible,  or wrongful
use of confidential information,  trade secrets, or secret processes; and (viii)
GXPT is not using any  patentable  invention,  confidential  information,  trade
secret,  or secret  process of others.  There is no right  under any  Intangible
necessary to the businesses of GXPT as presently conducted or as it contemplates
conducting, except such as are so designated in Section I of the GXPT Disclosure
Letter. Except as described in Section I of the GXPT Disclosure Letter, GXPT has
not infringed, is not infringing, and has not received notice of infringement in
respect of the Intangibles or asserted  Intangibles of others, nor has GXPT been
advised  by  counsel  or  others  that  it is  infringing  or may  infringe  the
Intangibles  or asserted  Intangibles  of others if any  currently  contemplated
business  activity  is  effectuated.  To the  knowledge  of  GXPT,  there  is no
infringement  by others of  Intangibles  of GXPT. As far as GXPT can  reasonably
foresee,  there is no  Intangible  or  asserted  Intangible  of others  that may
materially  adversely  affect the financial  condition,  results of  operations,
businesses,  properties,  assets,  liabilities, or future prospects of GXPT. All
material contracts, agreements,  instruments, leases, and licenses pertaining to
Intangibles  to  which  GXPT is a  party,  or to  which  any of its  businesses,
properties,  or assets are subject,  are in compliance in all material  respects
with all laws, rules,  regulations,  orders,  judgments,  and decrees binding on
GXPT or to which any of its businesses,  properties, or assets are subject. GXPT
did not register any trademark,  tradename or service mark, design, or name used
by  GXPT  to  identify  its  products,  businesses,  or  services.  Neither  any
stockholder of GXPT, any director, officer, or employee of GXPT, any relative or
affiliate of any stockholder of GXPT, any such director,  officer,  or employee,
nor any other  corporation  or enterprise in which any  stockholder of GXPT, any
such director,  officer,  or employee,  or any such relative or affiliate had or
now  has a 5% or  greater  equity  or  voting  or  other  substantial  interest,
possesses any Intangible which relates to the businesses of GXPT.

                                       12
<PAGE>

      (j) Questionable Payments. Neither GXPT, nor any director, officer, agent,
employee, or other person associated with, or acting on behalf of, GXPT, nor any
stockholder of GXPT has,  directly or indirectly:  used any corporate  funds for
unlawful  contributions,   gifts,  entertainment,  or  other  unlawful  expenses
relating to political activity; made any unlawful payment to foreign or domestic
government officials or employees or to foreign or domestic political parties or
campaigns from corporate  funds;  violated any provision of the Foreign  Corrupt
Practices Act of 1977, as amended; or made any bribe, rebate, payoff,  influence
payment, kickback, or other unlawful payment.

      (k)  Authority.  GXPT has all  requisite  power and  authority to execute,
deliver, and perform this Agreement. All necessary corporate proceedings of GXPT
have been duly taken to authorize the execution,  delivery,  and  performance of
this Agreement thereby. This Agreement has been duly authorized,  executed,  and
delivered by GXPT, constitutes the legal, valid, and binding obligation of GXPT,
and is enforceable as to GXPT in accordance with its terms.  Except as otherwise
set  forth  in this  Agreement,  no  consent,  authorization,  approval,  order,
license,  certificate,  or permit of or from, or declaration or filing with, any
federal,  state,  local, or other  governmental  authority or any court or other
tribunal is required by GXPT for the execution, delivery, or performance of this
Agreement by GXPT. No consent of any party to any material contract,  agreement,
instrument,  lease,  license,  arrangement,  or understanding to which GXPT is a
party,  or to which  it or any of its  businesses,  properties,  or  assets  are
subject,  is  required  for the  execution,  delivery,  or  performance  of this
Agreement  (except such consents referred to in Section K of the GXPT Disclosure
Letter); and the execution, delivery, and performance of this Agreement will not
(if the  consents  referred  to in Section K of the GXPT  Disclosure  Letter are
obtained prior to the Closing) violate, result in a breach of, conflict with, or
(with or without  the giving of notice or the  passage of time or both)  entitle
any party to  terminate  or call a default  under,  entitle any party to receive
rights or  privileges  that such party was not  entitled to receive  before this
Agreement was executed  under,  or create any  obligation on the part of GXPT to
which it was not subject  immediately  before this Agreement was executed under,
any term of any such material contract,  agreement,  instrument, lease, license,
arrangement,  or understanding,  or violate or result in a breach of any term of
the certificate of incorporation (or other charter document) or by-laws of GXPT,
or (if the  provisions of this  Agreement are  satisfied)  violate,  result in a
breach of, or conflict  with any law,  rule,  regulation,  order,  judgment,  or
decree binding on GXPT or to which any of its businesses,  properties, or assets
are subject,  which violation or breach would have a material  adverse effect on
GXPT. Neither GXPT, nor any of its officers, directors, employees, or agents has
employed any broker or finder or incurred any liability for any fee, commission,
or other compensation  payable by any person on account of alleged employment as
a broker or finder, or alleged performance of services as a broker or finder, in
connection  with  or  as  a  result  of  this  Agreement  or  the   transactions
contemplated hereby and in connection herewith.

Common Stock to be issued pursuant to Section 1.02(a) hereof,  and, in any case,
the shares of GXPT Common Stock issuable pursuant to Section 3.01(p) hereof, are
validly authorized and, when the such shares of GXPT Common Stock have been duly
delivered  pursuant to the terms of this  Agreement,  such shares of GXPT Common
Stock will be validly issued,  fully paid, and  nonassessable  and will not have
been issued,  owned or held in violation of any  preemptive  or similar right of
stockholder.

      (m) Insurance.  All policies of fire and other insurance  against casualty
and other losses and public liability insurance carried by GXPT are described in
Section M of the GXPT Disclosure  Letter (including the risks covered and limits
of such  policies) and are in full force and effect.  All premiums in respect of
such  policies for which  premium  notices have been  received have been paid in
full as the same become due and payable.  GXPT has not failed to give any notice
or present any claim under any insurance policy in due and timely fashion. There
are no actual claims or claims  threatened  in writing  against GXPT which could
come  within  the scope of such  coverage  nor are any such  policies  currently
threatened  with  cancellation.   There  are  no  outstanding   requirements  or
recommendations  by any  insurance  company that issued a policy with respect to
any of the respective  assets,  the businesses,  or operations of GXPT or by any
Board of Fire Underwriters or other body exercising  similar functions or by any
governmental authority requiring or recommending any repairs or other work to be
done  on,  or with  respect  to,  any of the  assets  of GXPT  or  requiring  or
recommending  any  equipment or  facilities to be installed on any premises from
which the  businesses  of GXPT is  conducted  or in  connection  with any of the
respective  assets  thereof.  GXPT does not have any  knowledge  of any material
proposed  increase  in  applicable  insurance  rates  or of  any  conditions  or
circumstances  applicable  to the  businesses  thereof that might result in such
increases.   No  such  policy  is  terminable  by  virtue  of  the  transactions
contemplated by this Agreement.

      (o) Trading Matters. At the date hereof and at the Closing Date:

            (i) the GXPT Common Stock is not  actively  traded and quoted in the
pink sheet market; and

            (ii) GXPT has not,  and shall not have taken any  action  that would
preclude,  or otherwise  jeopardize,  the inclusion of the GXPT Common Stock for
quotation on the OTC Bulletin Board.

      (p) Reorganization.

            (i) GXPT has not taken, has not agreed to take and will not take any
action (other than actions contemplated by this Agreement) that could reasonably
be expected to prevent the  transactions  contemplated  by this  Agreement  from
constituting  a  "reorganization"  under  section  368(b)  of the  Code or as an
acquisition  of in excess of 80% of the stock of a  corporation  in exchange for
property under Section 351 of the Code. GXPT is not aware of any agreement, plan
or  other  circumstance  that  could  reasonably  be  expected  to  prevent  the
transactions contemplated by this Agreement from so qualifying.

            (ii) GXPT has no plan or  intention  to  reacquire,  and,  to GXPT's
knowledge,  no person related to GXPT within the meaning of Treasury Regulations
Section 1.368-1 has a plan or intention to acquire, any of the GXPT Common Stock
pursuant to Section 1.02(a) hereof.

      (q) Completeness of Disclosure.  No  representation or warranty by GXPT in
this Agreement,  any of the financial  statement or other instruments or written
statements  provided  to the Advaxis  Shareholders  hereunder  or in  connection
herewith,  the GXPT  Disclosure  Letter or any  Schedules  or Exhibits  attached
hereto are made a part hereof contains or, and at the Closing Date will contain,
an untrue statement of material fact or omits or, at the Closing Date, will omit
to state a material fact required to be stated  therein or necessary to make the
statements made not misleading.

amended  since the time of the filing  thereof (the "GXPT SEC  Documents").  The
GXPT SEC Documents,  including, without limitation, any financial statements and

            (ii) Except as set forth in Section R of the GXPT Disclosure Letter,
the Company maintains disclosure controls and procedures required by Rule 13a-15
or 15d-15 under the Exchange Act; such controls and  procedures are effective to
ensure that all material information concerning the Company and its subsidiaries

preparation  of the Company's  filings with the SEC and other public  disclosure
documents.  To the extent any exist,  GXPT has  delivered  or made  available to
Advaxis copies of, all written  descriptions  of, and all policies,  manuals and
other documents promulgating, such disclosure controls and procedures. Except as
set forth in Section R of the GXPT Disclosure Letter, to GXPT's knowledge,  each
director and executive  officer thereof has filed with the SEC on a timely basis
all  statements  required by Section 16(a) of the Exchange Act and the rules and
regulations  thereunder since January 1, 2002. As used in Section  2.01(r),  the
term "file" shall be broadly construed to include any manner in which a document
or  information  is furnished,  supplied or otherwise made available to the SEC.

has received notice from any governmental  entity questioning or challenging the
accuracy,  completeness,  form  or  manner  of  filing  or  submission  of  such
certifications.

represents  and  warrants to Advaxis the  matters  and  statements  made in such
certificates.

      (s) Compliance with Law and Government Regulations.

            (i)  GXPT  is in  compliance  with,  and  is not  in  violation  of,
applicable  federal,  state,  local or foreign  statutes,  laws and  regulations
(including without  limitation,  any applicable  building,  zoning or other law,
ordinance  or  regulation)  affecting  its  properties  or the  operation of its
business.  GXPT is not subject to any order, decree,  judgment or other sanction
of any court, administrative agency or other tribunal.

            (ii) Each of GXPT, its directors and its senior  financial  officers

GXPT is in compliance with the provisions of such act applicable to it as of the

upon  the  advice  of  GXPT's   independent   auditors   and  outside   counsel,

statutory and regulatory  deadlines  therefore)  with all provisions of such act
which shall become applicable thereto after the date hereof.

      (t) Legal  Proceedings and History.  GXPT hereby  represents that,  unless
otherwise  disclosed  herein or in Section T of the GXPT Disclosure  Letter,  no
officer,  director or affiliate of GXPT, has been,  within the five years ending
on the Closing Date, a party to any bankruptcy  petition  against such person or
against  any  business  of which such  person  was  affiliated;  convicted  in a
criminal  proceeding  or subject  to a pending  criminal  proceeding  (excluding

has not been reversed, suspended or vacated.

      SECTION 2.02  REPRESENTATIONS  AND  WARRANTIES OF ADVAXIS.  Advaxis hereby
represents and warrants to, and agrees with, GXPT:

      (a) Organization and  Qualification.  Other than as set forth in Section A
of the  disclosure  letter,  of even date  herewith,  from  Advaxis to GXPT (the
"Advaxis  Disclosure  Letter"),   Advaxis  has  no  subsidiaries  or  affiliated
corporation  or owns any interest in any other  enterprise  (whether or not such
enterprise is a corporation).  Advaxis is a corporation duly organized,  validly
existing,  and in good standing under the laws of the State of Delaware with all
requisite  power and  authority,  and all  necessary  consents,  authorizations,
approvals,  orders,  licenses,  certificates,  and  permits  of  and  from,  and
declarations and filings with, all federal, state, local, and other governmental
authorities and all courts and other tribunals,  to own, lease, license, and use
its  properties  and  assets and to carry on the  businesses  in which it is now
engaged and the businesses in which it  contemplates.  Advaxis is duly qualified
to transact the  businesses  in which it is engaged and is in good standing as a
foreign  corporation  in every  jurisdiction  in which its  ownership,  leasing,
licensing,  or use of property or assets or the conduct of its businesses  makes
such qualification necessary.

                                       16
<PAGE>

      (b)  Capitalization.  Immediately  prior to the  Closing,  the  authorized
capital stock of Advaxis consists of 100,000 shares of Advaxis Common Stock, par
value $0.001 per share,  40,000 of which shares are issued and  outstanding  and
50,000 shares of preferred  stock,  par value $0.001 per share,  6,000 shares of
preferred  stock have been  designated  as Series A Preferred  Stock,  par value
$0.001 per share of which 3650.46 shares are issued and outstanding. Each of the
outstanding  shares of  Advaxis  Capital  Stock is validly  authorized,  validly
issued,  fully paid, and nonassessable,  has not been issued and is not owned or
held in violation of any preemptive  right of stockholders and by the owners set
forth in Section A of the Advaxis Disclosure Letter, in each case free and clear
of all liens, security interests, pledges, charges, encumbrances,  stockholders'
agreements, and voting trusts (other than the existing stockholders agreement to
be terminated prior to the Closing). Other than as set forth in Section A of the
Advaxis  Disclosure  Letter,  there is no  commitment,  plan, or  arrangement to
issue,  and no  outstanding  option,  warrant,  or other  right  calling for the
issuance  of,  any  share of  Advaxis  Capital  Stock or any  security  or other
instrument  convertible  into,  exercisable  for,  or  exchangeable  for Advaxis
Capital  Stock.  Other than as set forth in Section A of the Advaxis  Disclosure
Letter, there is outstanding no security or other instrument convertible into or
exercisable or exchangeable for Advaxis Capital Stock.

      (c)  Financial  Condition.  Advaxis has delivered to GXPT true and correct
copies of the  following:  audited  balance sheets of Advaxis as of December 31,
2002 and December 31, 2003 and  unaudited  balance  sheets of Advaxis as of June
30, 2003 and June 30, 2004; and audited statements of operations,  statements of
stockholders'  equity, and statements of cash flows of Advaxis for the two years
ended  December  31, 2002 and  December  31, 2003 and  unaudited  statements  of
operations,  statements of stockholders' equity, and statements of cash flows of
Advaxis for the periods ended June 30, 2003 and June 30, 2004. Each such balance
sheet  presents  fairly  the  financial  condition,   assets,  liabilities,  and
stockholders'  equity of Advaxis as of its date;  each such  statement of income
and consolidated  statement of stockholders'  equity presents fairly the results
of operations of Advaxis for the period  indicated;  and each such  statement of
cash flows presents  fairly the information  purported to be shown therein.  The
audited  financial  statements  referred to in this  Section  2.02(c)  have been
prepared  in  accordance  with GAAP in the United  States  consistently  applied
throughout the periods involved and are in accordance with the books and records
of Advaxis.  Except as set forth in Section C of the Advaxis  Disclosure Letter,
since June 30, 2004:

            (i)  There  has at no time  been a  material  adverse  change in the
      financial condition, results of operations,  business, properties, assets,
      liabilities, or future prospects of Advaxis.

            (ii) Advaxis has not  authorized,  declared,  paid,  or effected any
      dividend or  liquidating or other  distribution  in respect of its capital
      stock or any direct or indirect redemption,  puchase, or other acquisition
      of any stock of Advaxis (other than the pay-in-kind dividend to holders of
      Series A Preferred Stock as of August 15, 2004).

                                       17
<PAGE>

            (iii) The  operations  and businesses of Advaxis have been conducted
      in all respects only in the ordinary  course,  except for the transactions
      contemplated hereby and in connection herewith.

            (iv)  There  has  been no  accepted  purchase  order  or  quotation,
      arrangement,  or understanding for future sale of the products or services
      of Advaxis that Advaxis expects will not be profitable.

            (v) Advaxis has not suffered an  extraordinary  loss (whether or not
      covered by insurance) or waived any right of substantial value.

There is no fact known to Advaxis which materially  adversely  affects or in the
future (as far as Advaxis  can  reasonably  foresee)  may  materially  adversely
affect the financial  condition,  results of operations,  business,  properties,
assets,  liabilities,  or future prospects of Advaxis;  provided,  however, that
Advaxis  expresses  no opinion as to  political  or economic  matters of general
applicability.  Advaxis  has made  known,  or  caused to be made  known,  to the
accountants   or  auditors  who  have   prepared,   reviewed,   or  audited  the
aforementioned   consolidated   financial  statements  all  material  facts  and
circumstances  which could  affect the  preparation,  presentation,  accuracy or
completeness  thereof. The statement of operations of Advaxis for the year ended
December 31, 2003 shall be audited in accordance  with GAAP in the United States
consistently applied throughout the periods involved.

      (d)  Tax and  Other  Liabilities.  Advaxis  does  not  have  any  material
liability of any nature, accrued or contingent,  including,  without limitation,
liabilities for Taxes, and liabilities to customers or suppliers, other than the
following:

            (i)  Liabilities  for  which  full  provision  has been  made on the
      balance sheet and the notes  thereto,  if any (the "Last  Advaxis  Balance
      Sheet")  as of June 30,  2004 (the  "Last  Advaxis  Balance  Sheet  Date")
      referred to in Section 2.02(c); and

            (ii) Other liabilities  arising since the Last Advaxis Balance Sheet
      Date and prior to the  Closing  Date in the  ordinary  course of  business
      (which shall not include  liabilities to customers on account of defective
      products or services) or in connection with the transactions  contemplated
      hereby  or in  connection  herewith  which are not  inconsistent  with the
      representations  and warranties of Advaxis or any other  provision of this
      Agreement.

Without  limiting  the  generality  of  the  foregoing,  the  amounts  set up as
provisions  for Taxes on the Last Advaxis  Balance Sheet are  sufficient for all
accrued and unpaid Taxes of Advaxis,  whether or not due and payable and whether
or not disputed,  under tax laws, as in effect on the Last Advaxis Balance Sheet
Date or now in  effect,  for the  period  ended on such date and for all  fiscal
periods  prior  thereto.  The  execution,  delivery,  and  performance  of  this
Agreement  by Advaxis  will not cause any Taxes to be payable  other than by the
stockholders of Advaxis or cause any lien,  charge, or encumbrance to secure any
Taxes to be created either immediately or upon the nonpayment of any Taxes other

                                       18
<PAGE>

than on the  properties or assets of the  stockholders  of Advaxis.  Advaxis has
filed all federal, state, local, and foreign tax returns required to be filed by
it; has  delivered to the GXPT a true and correct copy of each such return which
was filed since incorporation;  has paid (or has established on the Last Advaxis
Balance  Sheet a reserve  for) all Taxes,  assessments,  and other  governmental
charges payable or remittable by it or levied upon it or its properties, assets,
income, or franchises which are due and payable; and has delivered to the GXPT a
true and correct  copy of any report as to  adjustments  received by it from any
taxing  authority  since  incorporation  and a statement  as to any  litigation,
governmental or other proceeding (formal or informal), or investigation pending,
threatened, or in prospect with respect to any such report or the subject matter
of such report.

      (e) Litigation and Claims.  There is no  litigation,  arbitration,  claim,
governmental or other proceeding (formal or informal), or investigation pending,
threatened,  or, to the best of Advaxis's  knowledge,  in prospect (or any basis
therefor  known to Advaxis),  with respect to Advaxis or any of its  businesses,
properties,  or assets.  Advaxis is not  affected by any  present or  threatened
strike or other labor  disturbance  nor to the knowledge of Advaxis is any union
attempting to represent any employee of Advaxis as collective  bargaining agent.
Advaxis is not in violation  of, or in default  with respect to, any law,  rule,
regulation,  order,  judgment, or decree which violation or default would have a
material adverse effect upon Advaxis; nor is Advaxis required to take any action
in order to avoid such violation or default.

      (f) Properties.

            (i) Advaxis does not own any legal or equitable interest in any real
      property.  Advaxis  has good  title to all  other  properties  and  assets
      material to Advaxis,  used in its business or owned by it (except real and
      other  properties  and assets as are held  pursuant  to leases or licenses
      described in Section F of the Advaxis Disclosure  Letter),  free and clear
      of  all  liens,  mortgages,  security  interests,  pledges,  charges,  and
      encumbrances  (except  such as are  listed  in  Section  F of the  Advaxis
      Disclosure Letter).

            (ii) All accounts and notes receivable reflected on the Last Advaxis
      Balance Sheet,  or arising since the Last Advaxis Balance Sheet Date, have
      been collected,  or are and will be good and collectible,  in each case at
      the aggregate recorded amounts thereof without right of recourse, defense,
      deduction,  return of goods, counterclaim,  offset, or set off on the part
      of the obligor, and, if not collected, can reasonably be anticipated to be
      paid within 180 days of the date incurred.

            (iii) All  production  in progress of Advaxis is usable,  in current
      production and marketable,  on a normal basis in the existing  business of
      Advaxis.

            (iv)  Attached  as Section F of the Advaxis  Disclosure  Letter is a
      true and  complete  list of the  classes of all  tangible  properties  and
      assets  owned by Advaxis  or leased or  licensed  by Advaxis  from or to a
      third party (including inventory but not including Intangibles, as defined
      in Section 2.02(i)), and with respect to such properties and assets leased
      or licensed by Advaxis from or to a third  party,  a  description  of such
      lease or license.  All such properties and assets (including  Intangibles)
      owned by Advaxis are  reflected on the Last Advaxis  Balance Sheet (except
      for  acquisitions  subsequent  to the Last Advaxis  Balance Sheet Date and
      prior to the Closing  Date which are set forth in Section F of the Advaxis
      Disclosure  Letter or are approved in writing by GXPT). All real and other
      tangible  properties  and assets owned by Advaxis or leased or licensed by
      Advaxis  from  or to a  third  party  are in  good  and  usable  condition
      (reasonable  wear and tear  which is not such as to affect  adversely  the
      operation of the business of Advaxis excepted).

                                       19
<PAGE>

            (v) To the best of Advaxis's  knowledge,  no real property  owned by
      Advaxis or leased or licensed by Advaxis  from or to a third party lies in
      an area which is, or will be,  subject to zoning,  use, or  building  code
      restrictions  which  would  prohibit,   and,  to  the  best  of  Advaxis's
      knowledge,  no state of facts  relating  to the  actions  or  inaction  of
      another person or entity or his or its ownership, leasing, or licensing of
      any real or personal  property  exists or will exist which would  prevent,
      the  continued  effective  ownership,  leasing,  or licensing of such real
      property  in  the  businesses  in  which  Advaxis  is now  engaged  or the
      businesses in which it contemplates engaging.

            (vi) The  properties  and assets  (including  Intangibles)  owned by
      Advaxis  (other than those leased or licensed by Advaxis to a third party)
      or leased or licensed by Advaxis  from a third party  constitute  all such
      properties  and assets  which are  necessary to the business of Advaxis as
      presently conducted or as it contemplates conducting.

            (vii) Advaxis has not caused or permitted its businesses properties,
      or assets to be used to generate,  manufacture,  refine, transport, treat,
      store,  handle,  dispose of, transfer,  produce,  or process any Hazardous
      Substance  (as such  term is  defined  in  Section  2.01(f)(v))  except in
      compliance  with  all  applicable  laws,   rules,   regulations,   orders,
      judgments,  and decrees,  and has not caused or permitted  the Release (as
      such term is defined in Section  2.01(f)(v)) of any Hazardous Substance on
      or off the site of any property of Advaxis.

      (g) Contracts and Other  Instruments.  Section G of the Advaxis Disclosure
Letter contains a true and correct  statement of the information  required to be
contained therein regarding material contracts, agreements, instruments, leases,
licenses,  arrangements,  or understandings with respect to Advaxis. Advaxis has
furnished to GXPT: (i) the certificate of  incorporation  and by-laws of Advaxis
(or, in each case, the comparable  charter  documents,  if any, under applicable

applicable bankruptcy,  insolvency,  and other laws affecting the enforceability
of creditors' rights generally) is enforceable as to them in accordance with its

understanding;  none of Advaxis or any other  party to any such  arrangement  or
understanding  has given notice of termination or taken any action  inconsistent

Advaxis  Disclosure Letter,  Advaxis enjoys peaceful and undisturbed  possession
under all leases and licenses under which it is operating.  Advaxis is not party
to or bound by any contract, agreement, instrument, lease, license, arrangement,

      (i) Patents,  Trademarks, Et Cetera. Advaxis does not own or have pending,
and is not  licensed or otherwise  permitted  to use,  any material  Intangible,
other than as described in Section I of the Advaxis Disclosure Letter. Except as
set forth in Section I of the Advaxis  Disclosure  Letter,  each  Intangible  is
validly issued and is currently in force and uncontested in all jurisdictions in
which it is used or in which such use is contemplated.  Section I of the Advaxis
Disclosure  Letter  contains a true and correct  listing of: (i) all Intangibles
which are owned (either in whole or in part), used by, or licensed to Advaxis or
which otherwise  relate to the businesses of Advaxis,  and a description of each
such Intangible which identifies its owner, registrant,  or applicant;  (ii) all
contracts,  agreements,  instruments, leases, and licenses and identification of
all parties thereto under which Advaxis owns or uses any Intangible  (whether or
not under license from third parties),  together with the  identification of the
owner,  registrant,  or applicant of each such Intangible;  (iii) all contracts,
agreements,  instruments, leases, and licenses and identification of all parties
thereto under which Advaxis grants the right to use any Intangible; and (iv) all
validity,  infringement,  right-to-use,  or other  opinions of counsel  (whether
in-house or outside) which concern the validity, infringement, or enforceability
of any  Intangible  owned or  controlled  by a party  other than  Advaxis  which
relates to the businesses, properties, or assets of Advaxis. Except as specified
in  Section I of the  Advaxis  Disclosure  Letter:  (i)  Advaxis is the sole and
exclusive  owner or licensee of, and (other than those  licensed by Advaxis to a
third  party)  has the right to use,  all  Intangibles;  (ii) no  Intangible  is
subject to any order, judgment, decree, contract, agreement,  instrument, lease,
or license restricting the scope of the use thereof;  (iii) during the last five
years,  Advaxis has not been  charged  with,  and has not charged  others  with,
unfair  competition,   infringement  of  any  Intangible,  or  wrongful  use  of
confidential  information,  trade secrets, or secret processes; and (iv) Advaxis
is not using any patentable invention,  confidential information,  trade secret,
or secret process of others. There is no right under any Intangible necessary to
the  businesses  of  Advaxis  as  presently  conducted  or  as  it  contemplates
conducting,  except  such  as are so  designated  in  Section  I of the  Advaxis
Disclosure  Letter.  Except as set forth in Section I of the Advaxis  Disclosure
Letter,  Advaxis has not  infringed,  is not  infringing,  and has not  received
notice of infringement in respect of the Intangibles or asserted  Intangibles of
others,  nor has Advaxis been advised by counsel or others that it is infringing
or may  infringe  the  Intangibles  or  asserted  Intangibles  of  others if any
currently  contemplated  business  activity is effectuated.  To the knowledge of
Advaxis,  there is no infringement  by others of Intangibles of Advaxis.  To the
knowledge of Advaxis,  there is no Intangible  or asserted  Intangible of others
that may  materially  adversely  affect  the  financial  condition,  results  of
operations,  businesses, properties, assets, liabilities, or future prospects of

                                       22

Advaxis. All contracts, agreements, instruments, leases, and licenses pertaining
to Intangibles to which Advaxis is a party,  or to which any of its  businesses,
properties,  or assets are  subject,  are in  compliance  with all laws,  rules,
regulations,  orders,  judgments, and decrees binding on Advaxis or to which any
of its  businesses,  properties,  or assets are subject.  Except as set forth in
Section I of the Advaxis Disclosure Letter, there is no trademark,  tradename or
service  mark  used  by  Advaxis  to  identify,   respectively,   its  products,
businesses,  or  services.  Except  as set  forth in  Section  I of the  Advaxis
Disclosure Letter, none of the Advaxis Shareholders,  any director,  officer, or
employee of Advaxis, any relative or affiliate of any Advaxis Shareholder or any
such director,  officer, or employee, nor any other corporation or enterprise in
which the Advaxis Shareholder,  any such director,  officer, or employee, or any
such  relative or affiliate  had or now has a 5% or greater  equity or voting or
other  substantial  interest,  possesses  any  Intangible  which  relates to the
businesses of Advaxis.

      (j) Questionable  Payments.  Neither Advaxis,  nor any director,  officer,
agent,  employee,  or other  person  associated  with,  or acting on behalf  of,

corporate  funds for  unlawful  contributions,  gifts,  entertainment,  or other
unlawful expenses relating to political  activity;  made any unlawful payment to
foreign or domestic government  officials or employees or to foreign or domestic
political  parties or campaigns from corporate funds;  violated any provision of

deliver,  and perform this  Agreement.  All necessary  corporate  proceedings of
Advaxis  have  been  duly  taken  to  authorize  the  execution,  delivery,  and
performance  of  this  Agreement  by  Advaxis.  This  Agreement  has  been  duly
authorized,  executed,  and delivered by Advaxis,  constitutes the legal, valid,
and  binding  obligation  of  Advaxis,  and  is  enforceable  as to  Advaxis  in
accordance with its terms.  Except as otherwise set forth in this Agreement,  no

from,  or  declaration  or filing with,  any  federal,  state,  local,  or other
governmental authority or any court or other tribunal is required by Advaxis for
the execution, delivery, or performance of this Agreement by Advaxis. No consent
of any party to any material contract,  agreement,  instrument,  lease, license,
arrangement,  or  understanding  to which Advaxis is a party, or to which its or
any of its businesses,  properties,  or assets are subject,  is required for the
execution,  delivery,  or performance  of this  Agreement  (except such consents
referred to in Section K of the Advaxis Disclosure  Letter);  and the execution,
delivery,  and performance of this Agreement will not (if the consents  referred
to in  Section K of the  Advaxis  Disclosure  Letter are  obtained  prior to the
Closing) violate,  result in a breach of, conflict with, or (with or without the
giving of notice or the passage of time or both)  entitle any party to terminate
or call a default under,  entitle any party to receive rights or privileges that
such party was not entitled to receive  immediately  before this  Agreement  was
executed under, or create any obligation on the part of Advaxis or GXPT to which
it was not subject  immediately  before this Agreement was executed  under,  any
term of any such  material  contract,  agreement,  instrument,  lease,  license,
arrangement,  or understanding,  or violate or result in a breach of any term of
the  certificate  of  incorporation  or by-laws of  Advaxis  (or the  comparable
charter documents,  if any, under applicable law), or (if the provisions of this
Agreement are  satisfied)  violate,  result in a breach of, or conflict with any
law, rule, regulation, order, judgment, or decree binding on Advaxis or to which
any of its businesses, properties, or assets are subject. Except as set forth in
Section K of the  Advaxis  Disclosure  Letter,  neither  Advaxis  nor any of its
officers,  directors,  employees, or agents has employed any broker or finder or
incurred any liability for any fee, commission, or other compensation payable by
any person on account of alleged  employment  as a broker or finder,  or alleged
performance of services as a broker or finder, in connection with or as a result
of  this  Agreement  or  the  other  transactions  contemplated  hereby  and  in
connection herewith.

and other losses and public liability insurance carried by Advaxis are described

limits of such  policies) and are in full force and effect.  A full and complete
copy of each such insurance  policy has been provided to GXPT, and such policies
are summarized in Section L of the Advaxis  Disclosure  Letter.  All premiums in

policies  currently  threatened  with  cancellation.  There  are no  outstanding
requirements or  recommendations  by any insurance  company that issued a policy
with respect to any of the respective assets,  the businesses,  or operations of
Advaxis or by any Board of Fire  Underwriters or other body  exercising  similar

or other work to be done on, or with respect to, any of the respective assets of
Advaxis or requiring or recommending any equipment or facilities to be installed
on any premises from which the respective  businesses of Advaxis is conducted or
in connection with any of the respective  assets thereof.  Advaxis does not have
any knowledge of any material proposed increase in applicable insurance rates or

thereof that might result in such  increases.  No such policy is  terminable  by
virtue of the transactions contemplated by this Agreement.

or group of customers which, individually or in the aggregate,  represented more
than five (5%) percent of the gross  revenues of Advaxis taken as a whole during
the year ended  December 31,  2003,  nor is there any reason to believe that any
such terminations or cancellations of such magnitudes are pending or threatened.

      (o) Completeness of Disclosure.  No  representation or warranty by Advaxis
in this  Agreement  contains,  or at the Closing  Date will  contain,  an untrue

<PAGE>

            (iii) Each Advaxis Shareholder  acknowledges being informed that the

unregistered,  shall be  "restricted  securities" as defined in paragraph (a) of
Rule 144 under the Securities Act, and must be held indefinitely unless (a) they
are  subsequently  registered under the Securities Act, or (b) an exemption from
such registration is available.

            (iv)  Each  Advaxis  Shareholder   acknowledges  that  such  Advaxis
Shareholder  has been  afforded  access to all material  information  which such
Advaxis  Shareholder  has  requested  relevant  to  such  Advaxis  Shareholder's
decision  to  acquire  the  Purchase  Shares  and to  ask  questions  of  GXPT's
management and that, except as set forth herein,  neither GXPT nor anyone acting
on behalf of GXPT has made any  representations  or  warranties  to such Advaxis
Shareholder   which  have  induced,   persuaded,   or  stimulated  such  Advaxis
Shareholder  to acquire such Purchase  Shares.  Each Advaxis  Shareholder  shall
deliver to GXPT a completed investor  representation letter in the form attached

financial and business  matters to be capable of evaluating the merits and risks
of  the  prospective  investment  in  the  Purchase  Shares,  and  each  Advaxis
Shareholder  is and will be able to bear the economic risk of the  investment in
such Purchase Shares.

                                   ARTICLE III

                                    COVENANTS

      SECTION 3.01 COVENANTS OF GXPT. GXPT covenants and agrees that,  after the
date  hereof  and  through  the  earlier  of  the  Closing  or the  date  of the
termination of this Agreement pursuant to Article IV hereof (the earlier of such
times,  the "Release Time"),  unless Advaxis will otherwise  approve in writing,
which approval will not be unreasonably withheld:

            (a) (i) Until the Release Time, no dividend or  liquidating or other
distribution or stock split shall be authorized,  declared, paid, or effected by
GXPT in respect of the outstanding  shares of GXPT Common Stock other than the 1
for 200 reverse stock split referenced in 3.01(l) below.

                  (ii) Until the Release Time, no share of capital stock of GXPT
or warrant for any such share, right to subscribe to or purchase any such share,
or security  convertible  into, or  exchangeable  or  exercisable  for, any such
share, shall be issued or sold by GXPT other than the Offering.

            (b)  Until  the  Release  Time,   GXPT  will  afford  the  officers,
directors,  employees,  counsel, agents,  investment bankers,  accountants,  and
other  representatives  of Advaxis  and the Advaxis  Shareholders  free and full
access to the plants,  properties,  books, and records of GXPT. GXPT will permit
them to make extracts  from and copies of such books and records,  and will from
time to time furnish Advaxis and the Advaxis  Shareholders  with such additional
financial  and  operating  data  and  other  information  as  to  the  financial
condition, results of operations,  businesses,  properties, assets, liabilities,
or future prospects of GXPT as Advaxis or the Advaxis  Shareholders from time to
time may  request.  Until the  Release  Time,  GXPT will  cause the  independent
certified  public  accountants  of  GXPT  to  make  available  to  Advaxis,  its
independent certified public accountants, and the Advaxis Shareholders, the work
papers  relating to the audits of GXPT  referred  to in Section  2.01(c) of this

                                       26
<PAGE>

            (c) Until the Release Time, GXPT will conduct its affairs so that on
the Closing Date no  representation  or warranty of GXPT will be inaccurate,  no
covenant  or  agreement  of GXPT  will be  breached,  and no  condition  in this
Agreement will remain unfulfilled by reason of the actions or omissions of GXPT.
Except as otherwise consented to by Advaxis in writing,  until the Release Time,
GXPT will conduct its affairs in all respects only in the ordinary course.

            (d) Until the Release Time, GXPT will immediately advise Advaxis and
the Advaxis  Shareholders  in a detailed  written notice of any material fact or
occurrence or any pending or threatened  material occurrence of which it obtains
knowledge  and which (if existing and known at the date of the execution of this
Agreement)  would have been required to be set forth or disclosed in or pursuant
to this Agreement or in the GXPT Disclosure Letter, which (if existing and known
at any time prior to or at the Closing) would make the  performance by any party
of a covenant  contained in this Agreement  impossible or make such  performance
materially  more difficult  than in the absence of such fact or  occurrence,  or
which (if existing and known at the time of the Closing) would cause a condition
to any party's obligations under this Agreement not to be fully satisfied.

            (e) GXPT shall insure that all confidential  information  which GXPT
or  any of its  officers,  directors,  employees,  counsel,  agents,  investment
bankers,  or  accountants  may now  possess  or may  hereafter  create or obtain
relating  to  the  financial  condition,  results  of  operations,   businesses,
properties,  assets,  liabilities, or future prospects of Advaxis, any affiliate
of Advaxis,  or any customer or supplier of Advaxis or any such affiliate  shall
not be  published,  disclosed,  or made  accessible  by any of them to any other
person or entity  without  the  prior  written  consent  of  Advaxis;  provided,
however,  that the  restrictions  of this  sentence  shall  not apply (i) as may
otherwise  be  required  by law,  (ii) as may be  necessary  or  appropriate  in
connection with the  enforcement of this  Agreement,  or (iii) to the extent the
information  shall have otherwise  become publicly  available.  GXPT shall,  and
shall  cause all other such  persons  and  entities  to,  deliver to Advaxis all
tangible  evidence of the  confidential  information  relating  to Advaxis,  any
affiliate of Advaxis, or (insofar as such confidential  information was provided
by, or on behalf of, Advaxis,  or any such affiliate of Advaxis) any customer or
supplier of any of them or any such affiliate to which the  restrictions  of the
foregoing  sentence apply  immediately  after the  termination of this Agreement
pursuant to Article IV or V hereof.

            (f) Before GXPT releases any  information  concerning this Agreement
or any of the other transactions  contemplated  hereby or in connection herewith
which is intended for or may result in public dissemination  thereof, GXPT shall
cooperate  with Advaxis,  shall furnish drafts of all documents or proposed oral
statements  to Advaxis for comment,  and shall not release any such  information
without the written consent of Advaxis.  Nothing  contained herein shall prevent
GXPT from releasing any information if required to do so by law.

            (g) GXPT shall not make any agreement or reach any understanding not
approved  in writing  by  Advaxis as a  condition  for  obtaining  any  consent,
authorization, approval, order, license, certificate, or permit required for the
consummation of the transactions contemplated by this Agreement.

            (h) GXPT  shall  promptly  prepare  all  required  by law or, in the
reasonable  opinion of the parties hereto,  appropriate  public  disclosures and
regulatory filings, if any are legally required,  relating to this Agreement and
the  transactions  contemplated  hereby and in connection  herewith.  GXPT shall
furnish or cause to be furnished,  for inclusion in such public  disclosures and
regulatory filings,  such information about GXPT, and GXPT's security holders as
may be required or as may be reasonably requested by Advaxis, and shall continue
to furnish or cause to be  furnished  such  information  as is necessary to keep
such information correct and complete in all material respects until the Release
Time. GXPT represents and warrants that the information that it has furnished to
date,  taken as a whole,  does  not now,  and will not at any time  prior to the
Release Time, (i) contain an untrue statement of a material fact or (ii) omit to
state a material  fact  required to be stated  therein or  necessary to make the
statements therein not false or misleading.  GXPT shall take any action required
to be taken by it under  state  "blue-sky,"  securities,  or  take-over  laws in
connection  with the issuance of GXPT Common Stock pursuant to the  transactions
contemplated hereby and in connection herewith.  The filings made by GXPT within
the past five years with the SEC were, if filed under the Exchange Act, prepared
in accordance  with the then existing  requirements  of the Exchange Act and the
rules  and  regulations  thereunder  and,  if filed  under the  Securities  Act,
prepared in accordance with the then existing requirements of the Securities Act
and the rules and regulations thereunder. Such filings when filed, and the press
releases and other public  statements  GXPT has made subsequent to the last such
filing when considered together with such filings, did not at the time of filing
or issuance of the press  releases or other public  statements,  as the case may
be, and (with respect to the press  releases and other public  statements,  when
considered  together  with  such  filings)  do not now  (i)  contain  an  untrue
statement of a material  fact or (ii) omit to state a material  fact required to
be stated  therein or  necessary  to make the  statements  therein  not false or
misleading.

            (i) If,  prior to the  Release  Time,  GXPT  Common  Stock  shall be
recapitalized  or reclassified  or GXPT shall effect any stock  dividend,  stock
split, or reverse stock split of GXPT Common Stock,  other than the contemplated
1 for 200  reverse  stock  split,  then the  shares of GXPT  Common  Stock to be
delivered under this Agreement or upon exercise,  conversion, or exchange of any
security to be delivered under this Agreement or assumed by GXPT as contemplated
by this Agreement shall be appropriately and equitably  adjusted to the kind and
amount of shares of stock and other securities and property to which the holders
of such  shares of GXPT  Common  Stock or such  other  security  would have been
entitled  to  receive  had such  stock or such other  security  been  issued and
outstanding  as of the record  date for  determining  stockholders  entitled  to
participate in such corporate event.

            (j) GXPT shall  timely  prepare and file any  declaration  or filing
necessary to comply with any transfer tax statutes  that require any such filing
before the Closing.

            (k) Until the Release Time,  GXPT shall not, and shall not authorize
or permit any officer,  director,  employee,  counsel, agent, investment banker,
accountant,  or  other  representative  of  GXPT,  directly  or  indirectly,  to
contemplate  or enter  into  any  transaction  the  effect  of  which  may be to
prohibit,  restrict, or delay the consummation of the transactions  contemplated
by this Agreement or impair the contemplated  benefits to GXPT's stockholders of
the transactions contemplated by this Agreement.

            (l) Effective at the Closing,  GXPT shall cause its  certificate  of
incorporation  to be  amended  to (i) cause the  corporate  name  thereof  to be
changed to "Advaxis  Inc.",  (ii) have a 1 for 200 reverse stock split and (iii)
authorize  the number of shares of GXPT Common  Stock to be at least  50,000,000
shares.

            (m) Effective at the Closing,  each officer of GXPT shall tender his
or her respective  resignation and each member of the Board of Directors of GXPT
shall tender his or her respective  resignation therefrom and GXPT shall appoint
the following  individuals  as the sole directors of GXPT:  Roni Appel,  J. Todd
Derbin, Scott Flamm, Thomas McKearn and Steve Roth.

            (n) On or prior to the Closing  Date,  GXPT shall deliver to Advaxis
and the Advaxis  Shareholders the completed GXPT Disclosure Letter, which letter
shall be correct and complete in all material respects.

            (o) On or prior to the  Closing  Date,  the Board of  Directors  and
shareholders  of GXPT shall (i) adopt the 2004 Stock  Option Plan (the  "Plan"),
substantially  in the  form  attached  hereto  as  Exhibit  C and  (ii)  reserve
2,381,525  shares of GXPT  Common  Stock  for  issuance  under  the Plan,  to be
effective upon Closing.

            (p) On the Closing  Date,  752,600  new shares of GXPT Common  Stock
shall be  issued  and  delivered  in  certificated  form to, or to the order of,
Sunrise Securities Corp. and/or their respective designees.

            (q)  Prior  to  the  Closing  Date,   the  Board  of  Directors  and
shareholders  of GXPT shall have  authorized  and  approved  the  execution  and
delivery of this Agreement and all transactions  contemplated hereby,  including
without limitation the 1 for 200 reverse stock split.

      SECTION 3.02  COVENANTS  OF ADVAXIS.  Advaxis  covenants  and agrees that,
after the date hereof and through the Release Time,  unless GXPT will  otherwise
approve in writing, which approval will not be unreasonably withheld:

            (a)  Until  the  Release  Time,  no  amendment  will  be made in the
certificate  of  incorporation  or by-laws  (or,  in each case,  the  comparable
charter documents, if any, under applicable law) of Advaxis.

            (b) Until the  Release  Time,  no share of  Advaxis  Capital  Stock,
option or warrant for any such share, right to subscribe to or purchase any such
share, or security  convertible  into, or  exchangeable or exercisable  for, any
such  share,  shall be issued or sold by  Advaxis,  other than the  issuance  of
convertible promissory notes and the issuance of warrants related thereto (which
convertible  promissory  notes and warrants  shall be exchanged for Units on the
same terms as the Advaxis Notes),  or otherwise than as  contemplated  by, or in
connection with, this Agreement. Such subscribers or purchasers will be required
to comply with all of the securities  transaction exemption requirements imposed
on the Advaxis Shareholders under this Agreement.

                                       29
<PAGE>

            (c) Until the Release  Time,  no dividend  or  liquidating  or other
distribution or stock split shall be authorized,  declared, paid, or effected by
Advaxis in respect of the outstanding shares of Advaxis Capital Stock other than
in-kind  dividends  payable to holders of Advaxis  Series A  Preferred  Stock of
Advaxis,  as more fully described in Section C of the Advaxis Disclosure Letter.
Until the Release Time,  no direct or indirect  redemption,  purchase,  or other
acquisition shall be made by Advaxis of shares of Advaxis Capital Stock.

            (d) Until the Release  Time,  except in the  ordinary  course of its
business,  Advaxis  shall not borrow  money,  guarantee  the borrowing of money,
engage in any  transaction,  or enter into any material  agreement other than in
connection with the transactions  contemplated  hereby or in connection herewith
or otherwise pursuant to any currently  outstanding  credit line of Advaxis,  or
with  respect  to  any  agreements  or  modifications  to  agreements  with  the
University of  Pennsylvania,  or with respect to the incurrence of  indebtedness
pursuant to the  issuance of  convertible  promissory  notes and the issuance of
warrants related thereto (which convertible  promissory notes and warrants shall
be exchanged for Units on the same terms as the Advaxis Notes).  For purposes of
this Agreement,  references to "material",  as well as correlative  terms (e.g.,
materially, materiality, etc.), shall be deemed to refer to amounts of US$50,000
or more or effects or consequences of US$50,000 or more.

            (e) Until the  Release  Time,  Advaxis  will  afford  the  officers,
directors,  employees,  counsel, agents,  investment bankers,  accountants,  and
other  representatives of GXPT and lenders,  investors,  and prospective lenders
and investors free and full access to the plants, properties, books, and records
of Advaxis,  will permit them to make extracts from and copies of such books and
records,  and will from time to time furnish GXPT with such additional financial
and operating data and other information as to the financial condition,  results
of operations,  businesses, properties, assets, liabilities, or future prospects
of  Advaxis  as GXPT from time to time may  request.  Until  the  Release  Time,
Advaxis will cause the independent  certified  public  accountants of Advaxis to
make available to GXPT and its independent certified public accountants the work
papers relating to the audits of Advaxis  referred to in Section 2.02(c) of this
Agreement.

            (f) Until the Release Time, Advaxis will conduct its affairs so that
at the Closing,  no  representation or warranty of Advaxis will be inaccurate in
any material respect, no covenant or agreement of Advaxis will be breached,  and
no condition in this Agreement will remain  unfulfilled by reason of the actions
or  omissions of Advaxis.  Except as otherwise  consented to by GXPT in writing,
until the  Release  Time,  Advaxis  will use its best  efforts to  preserve  the
business  operations of Advaxis  intact,  to keep  available the services of its
present  personnel,  to  preserve  in  full  force  and  effect  the  contracts,
agreements,  instruments,  leases, licenses, arrangements, and understandings of
Advaxis, and to preserve the good will of its suppliers,  customers,  and others
having business relations with any of them. Until the Release Time, Advaxis will
conduct its affairs in all respects only in the ordinary  course,  other than in
connection with the matters referenced herein.

                                       30
<PAGE>

            (g) Until the Release Time, Advaxis will immediately advise GXPT and
the Advaxis  Shareholders  in a detailed  written notice of any material fact or
occurrence or any pending or threatened  material occurrence of which it obtains
knowledge  and which (if existing and known at the date of the execution of this
Agreement)  would have been required to be set forth or disclosed in or pursuant
to this Agreement or the Advaxis Disclosure Letter, which (if existing and known
at any time prior to or at the Closing) would make the  performance by any party
of a covenant  contained in this Agreement  impossible or make such  performance
materially  more difficult  than in the absence of such fact or  occurrence,  or
which (if existing and known at the time of the Closing) would cause a condition
to any party's obligations under this Agreement not to be fully satisfied.

            (h) Advaxis shall use its commercially  reasonable efforts to insure
that  all  confidential  information  which  Advaxis  or any  of its  respective
officers,   directors,   employees,  counsel,  agents,  investment  bankers,  or
accountants  may now possess or may hereafter  create or obtain  relating to the
financial  condition,  results of operations,  businesses,  properties,  assets,
liabilities, or future prospects of GXPT, any affiliate thereof, or any customer
or supplier thereof or of any such affiliate shall not be published,  disclosed,
or made  accessible  by any of them to any other person or entity at any time or
used by any of them  except  in the  ordinary  course  of  business  and for the
benefit of Advaxis;  provided,  however,  that the restrictions of this sentence
shall not apply (A) after this Agreement is terminated pursuant to Article IV or
V hereof or  otherwise,  (B) as may  otherwise be required by law, (C) as may be
necessary or appropriate in connection  with the  enforcement of this Agreement,
or (D) to the  extent  the  information  shall have  otherwise  become  publicly
available.

            (i)  Before  Advaxis   releases  any  information   concerning  this
Agreement or any of the  transactions  contemplated  by this Agreement  which is
intended  for, or may result in,  public  dissemination  thereof,  Advaxis shall
cooperate  with GXPT,  shall  furnish  drafts of all  documents or proposed oral
statements  to GXPT for  comment,  and shall not  release  any such  information
without the written  consent of GXPT,  which consent  shall not be  unreasonably
withheld.  Nothing  contained  herein shall prevent  Advaxis from  releasing any
information if required to do so by law or in connection with the Offering.

            (j) Advaxis shall not make any agreement or reach any  understanding
not  approved  in writing by GXPT as a  condition  for  obtaining  any  consent,
authorization, approval, order, license, certificate, or permit required for the
consummation of the transactions contemplated by this Agreement.

            (k) Advaxis shall furnish,  or cause to be furnished,  for inclusion
in the public  disclosures  or  regulatory  filings of GXPT or  otherwise or for
inclusion in GXPT's  filings under state  "blue-sky,"  securities,  or take-over
laws,  such  information  about  Advaxis or the  Advaxis  Shareholder  as may be
required  or as may be  reasonably  requested  by GXPT,  and shall  continue  to
furnish or cause to be furnished  such  information as is necessary to keep such
information correct and complete in all material respect until the Release Time.
Advaxis  represents and warrants that the  information  that it has furnished to
date,  taken as a whole,  does  not now,  and will not at any time  prior to the
Release Time, (i) contain an untrue statement of a material fact or (ii) omit to
state a material  fact  required to be stated  therein or  necessary to make the
statements therein not false or misleading.

                                       31

            (l) Advaxis shall timely prepare and file any  declaration or filing
necessary to comply with any transfer tax statutes  that require any such filing
before the Closing.

            (m) On or prior to the Closing  Date,  Advaxis shall deliver to GXPT
the  completed  Advaxis  Disclosure  Letter,  which  letter shall be correct and
complete in all material respects.

            (n)  Prior  to  the  Closing  Date,   the  Board  of  Directors  and
shareholders  of Advaxis  shall have  authorized  and approved the execution and
delivery of this Agreement and all transactions contemplated hereby.

      SECTION  3.03   COVENANTS  OF  THE  ADVAXIS   SHAREHOLDERS.   The  Advaxis
Shareholders covenant and agree, severally and not jointly, that, after the date
hereof and through  the Release  Time,  unless  GXPT will  otherwise  approve in
writing, which approval will not be unreasonably withheld, as follows:

            (a) Those Advaxis  Shareholders who are employees and members of the
management  of Advaxis  will use best  efforts to cause  Advaxis to perform each
covenant thereof set forth herein on a timely basis.

            (b) Until the earlier of the Release  Time,  no Advaxis  Shareholder
shall take any action the result of which shall be to cause  Advaxis to make any
amendment in the certificate of  incorporation or by-laws (or, in each case, the
comparable charter documents, if any, under applicable law) thereof.

            (c) Before any of the Advaxis Shareholders  releases any information
concerning  this  Agreement  or any of the  transactions  contemplated  by  this
Agreement which is intended for, or may result in, public dissemination thereof,
such Advaxis  Shareholder shall cooperate with GXPT, shall furnish drafts of all
documents or proposed oral statements to GXPT for comment, and shall not release
any such  information  without the written consent of GXPT,  which consent shall
not be unreasonably withheld. Nothing contained herein shall prevent the Advaxis
Shareholders  from  releasing any  information if required to do so by law or in
connection with the Offering.

            (d)  Each  Advaxis   Shareholder  shall  furnish,  or  cause  to  be
furnished,  for  inclusion  in the  public  disclosure  in  connection  with the
transactions  contemplated by this Agreement, or for inclusion in GXPT's filings
under state  "blue-sky,"  securities,  or take-over laws, such information about
the Advaxis  Shareholder  as may be required  under  applicable  law,  and shall
continue to furnish or cause to be furnished such information as is necessary to
keep such  information  correct and complete in all material  respect  until the
Release Time.  Each Advaxis  Shareholder  represents  and warrants,  solely with
respect to himself,  herself or itself, that the information in writing that he,
she or it has  furnished  to date  regarding  himself,  herself  or  itself  for
inclusion in any registration statement or other related public filings with the
SEC or in any of GXPT's filings under state  securities  laws, taken as a whole,
does not now, and will not at any time prior to the Release Time, (i) contain an
untrue  statement  of a  material  fact or (ii)  omit to state a  material  fact
required to be stated  therein or necessary to make the  statements  therein not
false or misleading.

addition,   shall  be  accurate   as  of  the   Closing   Date  as  though  such
representations  and  warranties  were then made in exactly the same language by

or  lack  thereof  on the  part  of  Advaxis  or the  Advaxis  Shareholders  (as
applicable) or changes beyond its control;  as of the Closing Date,  Advaxis and
the Advaxis  Shareholders  shall have  performed and complied with all covenants

warranties  made by Advaxis herein,  as well as the documents  delivered to GXPT
pursuant  hereto,  and,  to the  best  of  their  knowledge,  (i)  neither  such
representations and warranties,  nor any such document so delivered (A) contains
an untrue  statement  of a material  fact or (B) omits to state a material  fact

enforced,  or  deemed  applicable  to  the  transactions  contemplated  by  this
Agreement by any federal,  state,  local, or other governmental  authority or by
any court or other  tribunal,  including the entry of a preliminary or permanent
injunction,  which, in the reasonable judgment of GXPT, (i) makes this Agreement

delay  in the  ability  of  Advaxis  or  GXPT  to  consummate  the  transactions
contemplated  by this  Agreement,  (iii)  requires the  divestiture by GXPT of a
material  portion of the  business of either GXPT or of  Advaxis,  (iv)  imposes

reasonably  request in order to enable Advaxis and the Advaxis  Shareholders  to
determine whether the conditions to GXPT's obligations under this Agreement have
been met and otherwise to carry out the provisions of this Agreement.

            (d) All actions, proceedings, instruments, and documents required by

Shareholders,  (i) makes this Agreement or any of the transactions  contemplated
by this Agreement illegal,  or (ii) results in a delay in the ability of GXPT or
Advaxis to consummate any of the transactions  contemplated by this Agreement or
(iii)  otherwise  prohibits,  restricts  or  delays  consummation  of the  other
transactions contemplated by this Agreement or impairs the contemplated benefits
to the  Advaxis  Shareholders  of  this  Agreement  or  any of the  transactions
contemplated by this Agreement.

            (g) The parties to this Agreement shall have obtained at or prior to
the Closing Date all unconditional written approval to this Agreement and to the
execution,  delivery,  and  performance  of  this  Agreement  by each of them of
relevant  governmental  authorities,  if any, having  jurisdiction  over GXPT or
Advaxis or the subject matter of this Agreement.

            (h) At or  prior to the  Closing  Date,  GXPT  shall  have  made all
filings,  and  taken  all  actions,  necessary  to  comply  with  all  reporting
requirements   under  federal  and  state  securities  laws  (including  without
limitation,  applicable  "blue-sky"  laws with  regard to the  issuance  of GXPT
Common Stock as contemplated by this Agreement)  other than the filing of Form D
up to 15 days  following  the Closing.  Without  limiting the  generality of the
foregoing,  any  prescribed  periods within which a "blue sky" or securities law
administrator  may disallow  GXPT's notice of reliance on an exemption from such
state's requirements, shall have elapsed at or prior to the Closing Date.

            (i) The parties to this Agreement shall have obtained at or prior to
the Closing Date all consents  required for the consummation of the transactions
contemplated  by this Agreement from any unrelated  third party to any contract,
agreement,  instrument,  lease, license,  arrangement, or understanding to which
any of them is a  party,  or to  which  any of them or any of  their  respective
businesses, properties, or assets are subject.

            (j) Advaxis shall conduct a due diligence review of GXPT, including,
without  limitation,  a review of the GXPT  Disclosure  Letter and the documents
referenced  therein  delivered  prior to the  Closing  Date,  and same  shall be
satisfactory in the reasonable opinion of Advaxis.

            (k)  At  the  Closing  Date,  GXPT  shall  have  no  assets  and  no
liabilites,  determined in  accordance  with GAAP in effect in the United States
applied on a basis  consistent  with that of the  financial  statements  of GXPT
hereinabove referenced.

            (l) At or prior to the  Closing  Date,  a minimum  investment  of at
least $1,500,000  shall be placed in escrow with Continental  Transfer and Trust
Company, the escrow agent, in connection with the Offering.

            (m) At or prior to the Closing Date,  the officers,  directors,  and
holders of 5% or more of the outstanding GXPT Common Stock  immediately prior to
such date shall have  executed and  delivered  to Advaxis an agreement  mutually
acceptable  in form and  substance to each of such person or entity,  on the one
hand, and Advaxis, on the other hand, providing for restrictions on resale and a
"leak-out" of securities for a 90 day period following the Closing Date.

      SECTION  4.03  OPTIONAL  ABANDONMENT.  In  addition to the  provisions  of
Section  4.01 and Section  4.02 above,  the  transactions  contemplated  by this
Agreement   may  be   abandoned   or   terminated   at  or  before  the  Closing
notwithstanding  adoption and approval of this  Agreement  and the  transactions
contemplated hereby by the stockholders of the parties hereto:

            (a) by  mutual  agreement  of the  Boards of  Directors  of GXPT and
Advaxis;

                                       36
<PAGE>

            (b) at the option of GXPT's Board of Directors, if facts exist which
render  impossible  compliance  with one or more of the  conditions set forth in
Section 4.01 and such are not waived by GXPT;

            (c) at the option of Advaxis's Board of Directors or by the election
of the Advaxis  Shareholders if facts exist which render  impossible  compliance
with one or more of the  conditions  set forth in Section  4.02 and such are not
waived by Advaxis; and

            (d) at the option of Advaxis's  Board of Directors  and GXPT's Board
of  Directors,  if the  Closing  Date shall not have  occurred  on or before the
Initial Closing Date;  provided,  that if Advaxis pays GXPT $15,000 (such amount
is  non-refundable)  prior to the Initial  Closing  Date,  then the Closing Date
shall be extended for an additional forty-five (45) day period.

      SECTION 4.04 EFFECT OF ABANDONMENT.  If the  transactions  contemplated by
this  Agreement  are abandoned or terminated as provided for in this Article IV,
except for Sections 3.01(e),  3.02(h), 4.01, 4.02 and 4.03, this Agreement shall
forthwith become wholly void and of no further force or effect without liability
on the part of either  party to this  Agreement  or on the part of any  officer,
director,  controlling person (if any), employee, counsel, agent, or stockholder
thereof; provided, however, that nothing in this Section 4.04 shall release GXPT
or Advaxis or any  officer,  director,  controlling  person (if any),  employee,
counsel,  agent, or stockholder  thereof from liability for a willful failure to
carry out its respective obligations under this Agreement.

                                    ARTICLE V

this Agreement are  consummated,  all costs and expenses  incurred in connection
with this Agreement and the transactions  contemplated  hereby,  will be paid by
the party incurring such expense or as otherwise agreed to herein.

      SECTION  5.02 BROKERS AND  FINDERS.  Except as set forth on Schedule  5.2,
each of the parties  hereto  represents,  as to itself,  that no agent,  broker,
investment  banker or firm or person is or will be entitled  to any  broker's or
finder's fee or any other  commission or similar fee in  connection  with any of
the transactions contemplated by this Agreement,  except as may be otherwise set
forth herein or by separate document.

      SECTION 5.03 NECESSARY ACTIONS. Subject to the terms and conditions herein
provided,  each of the parties  hereto agrees to use all  reasonable  efforts to
take,  or cause to be taken,  all  action  and to do,  or cause to be done,  all
things  necessary,  proper or advisable under applicable laws and regulations to
consummate and make effective the  transactions  contemplated by this Agreement.
In the event at any time after the Closing,  any further  action is necessary or
desirable  to carry out the  purposes of this  Agreement,  the proper  executive
officers  and/or  directors  of GXPT or  Advaxis,  as the  case  may be,  or the
relevant  Advaxis  Shareholders  or  Advaxis  Shareholders  will  take  all such
necessary action.
