3.       Covenants of SELLER.

         3.1      SELLER  will not use or disclose  to  third-parties  any trade
                  secrets  or  other  proprietary  or  confidential  information
                  pertaining to any aspect of the Business.

         3.2      SELLER acknowledges that violation of any of the provisions of
                  this  Section 3 will cause  irreparable  loss and harm to both
                  the Company and BUYER which cannot be reasonably or adequately
                  compensated  by damages in an action at law.  Accordingly,  in
                  the event of a breach or threatened breach by SELLER of any of
                  the  provisions  of this  Section 3, each of the  Company  and
                  BUYER  shall be  entitled to  injunctive  and other  equitable
                  relief to  prevent  or cure any  breach or  threatened  breach
                  thereof,  and SELLER  agrees  that it will not be a defense to
                  any  request  for such relief that the Company or BUYER has an
                  adequate  remedy at law.  Notwithstanding  the foregoing,  the
                  Company and BUYER  shall have other  legal  remedies as may be
                  appropriate  under the  circumstance  including,  inter  alia,
                  recovery of damages occasioned by such breach. For purposes of
                  any  proceeding  under  or with  respect  to this  Section  3,
                  SELLER,  the Company and BUYER submit to the  jurisdiction  of
                  the  courts  of the  State of New York and of New York  County
                  located in the State of New York; and each agrees not to raise
                  and waives any  objection to or defense  based on the venue of
                  any such court or forum non conveniens.



         3.3      A court of competent jurisdiction, if it determines any of the
                  provisions of this Section 3 to be unreasonable in scope, time
                  or geography,  is hereby authorized by SELLER, the Company and
                  BUYER to enforce the same in such narrower scope, shorter time
                  or lesser  geography as such court determines to be reasonable
                  under all the circumstances.

                           condition  of the Company at said  dates.  As at said

                           (contingent  or otherwise)  or assets,  which are not
                           disclosed in the Financial Statements or, in the case
                           of  liabilities,   reserved  against   therein.   The

                           practices  in United  States]  consistently  applied.
                           Since the  dates of the  Financial  Statements  there
                           have  been no  adverse  changes  in the  business  or
                           financial  condition  of the  Company and the Company
                           has  not  incurred  any  additional   obligations  or
                           liabilities except trade debts in the ordinary course
                           of business.  The BUYER  acknowledges  that it is not
                           acquiring any intellectual property of the Company as
                           such  property  has  been  sold   subsequent  to  the
                           preparation   of   the    aforementioned    Financial

                           license to use the intellectual property as described
                           in schedule 5.1(e) such license being an asset of the

                           sufficient  to allow  the  Company  to carry  out its
                           business as if the  intellectual  property were owned
                           by the Company.

                           required  to pay.  The  Company  has  made  provision
                           sufficient   to  satisfy  any  and  all  accrued  tax
                           liabilities.

                  (f)      Apart from the  Company  Assets and other  assets set

                           producing and selling the product.

                  of confidentiality contained herein.

         20.3     The BUYER  agrees that it may not  commence  or  continue  any

                  herein to complete any part of the contemplated  transactions,

21.      Time of the Essence; Computation of Time.

         Time is of the essence of each and every  provision of this  Agreement.
         Whenever the last day for the exercise of any right or the discharge of
         any duty under this  Agreement  shall fall upon  Saturday,  Sunday or a
         federal,  public or legal holiday,  the party having such right or duty
         shall have until 5:00 p.m. on the next succeeding  regular business day
         to exercise such right or to discharge such duty.

22.      Severability.

         If any term or other provision of this Agreement is invalid, illegal or
         incapable of being  enforced by any rule of law or public  policy,  all
         other terms and provisions of this Agreement will  nevertheless  remain
         in full force and effect so long as the economic or legal  substance of
         the  transactions  contemplated  hereby is not  affected  in any manner
         adverse to any party hereto.  Upon any such determination that any term
         or other provision is invalid,  illegal or incapable of being enforced,
         the  parties  hereto  will  negotiate  in good  faith  to  modify  this
         Agreement so as to effect the original intent of the parties as closely
         as possible in an  acceptable  manner to the end that the  transactions
         contemplated by this Agreement are consummated to the extent possible.

         in such case one  counterpart of this Agreement shall consist of enough
         of such copies to reflect the  signatures  of all of the parties.  This
         Agreement  may be executed in two or more  counterparts,  each of which
         shall be an original,  and each of which shall  constitute  one and the
         same  agreement.  Any  party  may  deliver  an  executed  copy  of this




         Agreement  and  of  any  documents  contemplated  hereby  by  facsimile
         transmission  to another  party and such  delivery  shall have the same
         force and effect as any other  delivery  of a manually  signed  copy of
         this Agreement or of such other documents.



                            INTENTIONALLY LEFT BLANK

Purchase  Agreement among the  shareholders of BioSource  Therapeutics,  Inc., a
Delaware corporation  ("SELLER") and Innovative Technology  Acquisition Corp., a
Delaware corporation ("BUYER").

Whereas,  from the time of execution of the Share Purchase  Agreement  until the
date hereof there have been certain  changes in the  shareholdings  of BioSource
Therapeutics, such changes necessitating certain changes to said agreement;

NOW THEREFORE, the parties hereby agree as follows:

         1.       The parties ratify and reaffirm the Share  Purchase  Agreement
                  dated July 30,  2002  except as it is  modified  herein,  such
                  modifications  taking  precedence  over  any  clauses  to  the
                  contrary of earlier date.

         2.       Sections 1.1 and 1.2 shall be modified to reflect a closing on
                  or before October 25, 2002.

         3.       The total number of shares issued and outstanding of BioSource
                  Therapeutics shall be amended in all sections to indicate that
                  there are 1,175 shares issued and outstanding.  Shares of ITAQ
                  to be  distributed  shall  be  distributed  according  to  the
                  attached schedule.

         4.       Section  19.2 shall be modified to remove  Paul  Zuromski  and

                  Stephen  Leibtag  as  President/Director  and Rona  Taylor  as
                  Director/Treasurer.

         5.       If a minimum of $500,000 in capital is not raised to implement
                  the  business of BioSource as  contemplated  in the  agreement
                  then the  each  party  individually  may  seek to  unwind  the
                  transaction by returning the stock of each respective company.
                  It is the responsibility of the officers and directors of both
                  ITAQ and BioSource to actively  participate  in the raising of
                  such funds.

         6.       All other  provisions  of the  agreement  shall remain in full
