Warrant No. 64          STOCK PURCHASE WARRANT             No. of Shares 200,000

                  To Subscribe for and Purchase Common Stock of
                                 CONSYGEN, INC.

         THIS CERTIFIES that, for value received,  Howard R. Baer (together with
any subsequent transferees of all or any portion of this Warrant, the "Holder"),
is entitled, upon the terms and subject to the conditions hereinafter set forth,
to  subscribe  for  and  purchase  from  CONSYGEN,  INC.,  a  Texas  corporation
(hereinafter  called  the  "Company"),  at the  price  hereinafter  set forth in
Section 2, up to two hundred  thousand  (200,000) fully paid and  non-assessable
shares (the "Shares") of the Company's  Common Stock,  $.003 par value per share
(the "Common Stock").

        1.  Definitions.  As used  herein  the  following  term  shall  have the
following meaning:

        "Act"  means the  Securities  Act of 1933,  as  amended,  or a successor
statute  thereto and the rules and  regulations  of the  Securities and Exchange
Commission  issued  under that Act, as they each may,  from time to time,  be in
effect.

         2.  Purchase  Rights.  Subject to this Section 2, the  purchase  rights
represented  by this Warrant shall be  exercisable  by the Holder in whole or in
part commencing on the date hereof.

         Subject to the terms hereof,  the purchase  rights  represented by this
Warrant shall expire two (2) years from the date hereof.

        Subject to this Section 2, this Warrant may be exercised for Shares at a
price of five dollars  ($5.00) per share,  subject to  adjustment as provided in
Section 6 (the "Warrant Purchase Price").

        This Warrant may be redeemed by the Company upon 60 days written  notice
to the  Holder  hereof at a price  equal to the  product of the number of Shares
issuable  hereunder  and the par value of the Shares  ($.003).  The  Company may
exercise its  redemption  right by delivering  or mailing to the Holder  written
notice of redemption to the address according to the Company's  records.  Within
60 days after the date of the  Company's  notice of  redemption  hereunder,  the
Holder shall tender to the Company at its principal  offices the  certificate or
certificates  representing  this  Warrant,  all in form suitable for transfer of
this Warrant to the  Company,  together  with such  documents as the Company may
reasonably  require  to  effectuate  such  transfer.  Upon its  receipt  of such
certificate(s),  the Company  shall deliver or mail to the






Holder a check in the amount of the  redemption  price  determined in accordance
herewith. After the time at which the certificate(s) is required to be delivered
to the Company for transfer to the Company  hereunder,  the Holder shall have no
rights  hereunder,  including  without  limitation  the  right to  exercise  the
purchase rights evidenced by this Warrant.  In the event that the Company elects
to exercise  its  redemption  right  hereunder,  it may do so by  canceling  the
certificate(s)  evidencing  this Warrant and  depositing  the  redemption  price
determined hereunder in a bank account for the benefit of the Holder,  whereupon
this Warrant shall be, for all purposes, canceled and neither the Holder nor any
transferee  shall have any rights  hereunder.  In addition to any other legal or
equitable  remedies  which it may have,  the  Company  may enforce its rights by
actions for specific performance (to the extent permitted by law).

         3. Exercise of Warrant. Subject to Section 2 above, the purchase rights
represented by this Warrant may be exercised,  in whole or in part and from time
to time,  by the  surrender  of this  Warrant  and the duly  executed  Notice of
Exercise (the form of which is attached as Exhibit A) at the principal office of
the Company and by the payment to the Company,  by check,  of an amount equal to
the then applicable Warrant Purchase Price per share multiplied by the number of
Shares then being  purchased.  Upon  exercise,  the Holder  shall be entitled to
receive, within a reasonable time, a certificate or certificates,  issued in the
Holder's name or in such name or names as the Holder may direct,  for the number
of Shares so purchased.  The Shares so purchased shall be deemed to be issued as
of the close of  business  on the date on which  this  Warrant  shall  have been
exercised.

         4. Shares to be Issued;  Reservation of Shares.  The Company  covenants
that the Shares that may be issued  upon the  exercise  of the  purchase  rights
represented by this Warrant will, upon issuance in accordance herewith, be fully
paid and non-assessable, and free from all liens and charges with respect to the
issue thereof. During the period within which the purchase rights represented by
the Warrant may be exercised,  the Company will at all times have authorized and
reserved,  for the purpose of issuance  upon  exercise  of the  purchase  rights
represented by this Warrant,  a sufficient  number of shares of its Common Stock
to provide for the exercise of the right represented by this Warrant.

         5. No Fractional  Shares. No fractional shares shall be issued upon the
exercise of this Warrant. In lieu thereof, a cash payment shall be made equal to
such  fraction  multiplied  by the fair  market  value of such  shares of Common
Stock, as determined in good faith by the Company's Board of Directors.

         6. Adjustments of Warrant Purchase Price and Number of Shares. If there
shall  be any  change  in  the  Common  Stock  of the  Company  through  merger,
consolidation, reorganization,  recapitalization, stock dividend, stock split or
other change in the corporate structure of the Company,  appropriate adjustments
shall be made by the Board of Directors of the Company (or if the Company is not
the surviving corporation in any such transaction, the Board of Directors of the
surviving  corporation)  in the aggregate  number and kind of shares  subject to
this  Warrant,  and the  number  and kind of shares and the price per share then
applicable to shares covered by the unexercised portion of this Warrant.

         7. No Rights as Shareholders.  This Warrant does not entitle the Holder
to any voting  rights or other rights as a  shareholder  of the Company prior to
exercise  of  this  Warrant  and  the  payment  for  the  Shares  so  purchased.
Notwithstanding the foregoing, the Company agrees to transmit to the Holder such
information,  documents and reports as are generally






distributed to holders of the capital stock of the Company concurrently with the
distribution  thereof to the  shareholders.  Upon valid exercise of this Warrant
and  payment for the Shares so  purchased  in  accordance  with the terms of the
Warrant,  the  Holder or the  Holder's  designee,  as the case may be,  shall be
deemed a shareholder of the Company.

         8. Sale or Transfer of the Warrant and the Shares;  Legend. The Warrant
and the Shares  shall not be sold or  transferred  unless  either (i) they first
shall have been registered  under applicable State Securities laws, or (ii) such
sale or transfer is exempt from the registration requirements of such laws. Each
certificate  representing  any  Warrant  shall bear the legend set out on page 1
hereof.   Each   certificate   representing  any  Shares  shall  bear  a  legend
substantially in the following form, as appropriate:

         9. THE SHARES  EVIDENCED  HEREBY HAVE BEEN ACQUIRED FOR  INVESTMENT AND
NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION  THEREOF. NO
SUCH SALE OR  DISTRIBUTION  MAY BE EFFECTED  WITHOUT AN  EFFECTIVE  REGISTRATION
STATEMENT  RELATED THERETO UNDER APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO
AN EXEMPTION UNDER APPLICABLE STATE SECURITIES LAWS.

         10. Such Warrant and Shares may be subject to  additional  restrictions
on transfer imposed under applicable state and federal securities law.

         11. Modifications and Waivers. This Warrant may not be changed, waived,
discharged or terminated  except by an instrument in writing signed by the party
against which enforcement of the same is sought.

         12.  Notices.  Any  notice,  request  or  other  document  required  or
permitted  to be  given or  delivered  to the  Holder  or the  Company  shall be
delivered, or shall be sent by certified or registered mail, postage prepaid, to
the Holder at its  address  shown on the books of the  Company or in the case of
the Company,  at the address  indicated  therefor on the signature  page of this
Warrant, or, if different, at the principal office of the Company.

         13. Loss,  Theft,  Destruction  or Mutilation  of Warrant.  The Company
covenants  with  the  Holder  that  upon  its  receipt  of  evidence  reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this Warrant or any stock  certificate  and, in the case of any such loss, theft
or destruction,  of an indemnity or security reasonably  satisfactory to it, and
upon reimbursement to the Company of all reasonable expenses incidental thereto,
and upon surrender and  cancellation  of this Warrant or stock  certificate,  if
mutilated, the Company will make and deliver a new Warrant or stock certificate,
of like tenor, in lieu of the lost,  stolen,  destroyed or mutilated  Warrant or
stock certificate.

         14.  Representations  and  Warranties  of  Holder.  By  accepting  this
Warrant, the Holder represents and warrants that he, she or it is acquiring this
