                             STOCK PURCHASE WARRANT


                To Purchase ___________ Shares of Common Stock of

                        GENEREX BIOTECHNOLOGY CORPORATION

     THIS CERTIFIES that, for value received, ___________________________ (the
"Holder"), is entitled, upon the terms and subject to the conditions hereinafter
set forth, at any time on or after August 12, 2000 (the "Issuance Date") and on
or prior to the close of business on August 12, 2003 (the "Termination Date")
but not thereafter, to subscribe for and purchase from Generex Biotechnology
Corporation, a Delaware corporation (the "Company"), up to ________ shares (the
"Warrant Shares") of Common Stock, $.001 par value, of the Company (the "Common
Stock"). The purchase price of one share of Common Stock (the "Exercise Price")
under this Warrant shall be $12.1469 (115% of the closing bid price of the
Company's Common Stock on the date immediately preceding the execution of the
that certain Common Stock Purchase Agreement, dated August 14, 2000 between the
Company and the Traders Bloom Limited (the "Purchase Agreement")). The Exercise
Price and the number of shares for which the Warrant is exercisable shall be
subject to adjustment as provided herein. In the event of any conflict between
this Warrant and the Purchase Agreement, the Purchase Agreement shall control.
Capitalized terms used and not otherwise defined herein shall have the meanings
set forth for such terms in the Purchase Agreement.

     1. Title to Warrant. Prior to the Termination Date hereof and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
holder hereof in person or by duly authorized attorney, upon surrender of this
Warrant together with the Assignment Form annexed hereto properly endorsed.

     2. Authorization of Shares. The Company covenants that all shares of Common
Stock which may be issued upon the exercise of rights represented by this
Warrant will, upon exercise of the rights represented by this Warrant, be duly
authorized, validly issued,

                                        1


fully paid and nonassessable and free from all taxes, liens and charges in
respect of the issue thereof (other than taxes in respect of any transfer
occurring contemporaneously with such issue).

     3. Exercise of Warrant. Except as provided in Section 4 herein, exercise of
the purchase rights represented by this Warrant may be made at any time or times
on or after the Issuance Date hereof and before the close of business on the
Termination Date hereof. Exercise of this Warrant or any part hereof shall be
effected by the surrender of this Warrant and the Notice of Exercise Form
annexed hereto duly executed, at the office of the Company (or such other office
or agency of the Company as it may designate by notice in writing to the
registered holder hereof at the address of such holder appearing on the books of
the Company) and upon payment of the Exercise Price of the shares thereby
purchased by wire transfer or cashier's check drawn on a United States bank, the
holder of this Warrant shall be entitled to receive a certificate for the number
of shares of Common Stock so purchased. Certificates for shares purchased
hereunder shall be delivered to the holder hereof within three (3) Trading Days
after the date on which this Warrant shall have been exercised as aforesaid.
This Warrant shall be deemed to have been exercised and such certificate or
certificates shall be deemed to have been issued, and Holder or any other person
so designated to be named therein shall be deemed to have become a holder of
record of such shares for all purposes, as of the date the Warrant has been
exercised by payment to the Company of the Exercise Price and all taxes required
to be paid by Holder, if any, pursuant to Section 5 prior to the issuance of
such shares, have been paid. If this Warrant shall have been exercised in part,
the Company shall, at the time of delivery of the certificate or certificates
representing Warrant Shares, deliver to Holder a new Warrant evidencing the
rights of Holder to purchase the unpurchased shares of Common Stock called for
by this Warrant, which new Warrant shall in all other respects be identical with
this Warrant. This Warrant may also be exercised by means of a "cashless
exercise" in which the holder shall be entitled to receive a certificate for the
number of shares equal to the quotient obtained by dividing [(A-B) (X)] by (A),
where:

(A) = the average of the high and low trading prices per share of Common Stock
on the Trading Day preceding the date of such election;

(B) =  the Exercise Price of the Warrants; and

(X) = the number of shares issuable upon exercise of the Warrants in accordance
with the terms of this Warrant.

     4. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to the Exercise Price.

     5. Charges, Taxes and Expenses. Issuance of certificates for shares of
Common Stock upon the exercise of this Warrant shall be made without charge to
the holder hereof for any issue or transfer tax or other incidental expense in
respect of the issuance of such certificate, all of which taxes and expenses
shall be paid by the Company, and such certificates shall be issued in the name
of the holder of this Warrant or in such name or names as may be

                                        2


directed by the holder of this Warrant; provided, however, that in the event
certificates for shares of Common Stock are to be issued in a name other than
the name of the holder of this Warrant, this Warrant when surrendered for
exercise shall be accompanied by the Assignment Form attached hereto duly
executed by the holder hereof; and the Company may require, as a condition
thereto, the payment of a sum sufficient to reimburse it for any transfer tax
incidental thereto.

     6. Closing of Books. The Company will not close its shareholder books or
records in any manner which prevents the timely exercise of this Warrant.

     7. Transfer, Division and Combination. (a) Subject to compliance with any
applicable securities laws, transfer of this Warrant and all rights hereunder,
in whole or in part, shall be registered on the books of the Company to be
maintained for such purpose, upon surrender of this Warrant at the principal
office of the Company, together with a written assignment of this Warrant
substantially in the form attached hereto duly executed by Holder or its agent
or attorney and funds sufficient to pay any transfer taxes payable upon the
making of such transfer. Upon such surrender and, if required, such payment, the
Company shall execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees and in the denomination or denominations specified in such
instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall
promptly be cancelled. A Warrant, if properly assigned, may be exercised by a
new holder for the purchase of shares of Common Stock without having a new
Warrant issued.

          (b) This Warrant may be divided or combined with other Warrants upon
     presentation hereof at the aforesaid office of the Company, together with a
     written notice specifying the names and denominations in which new Warrants
     are to be issued, signed by Holder or its agent or attorney. Subject to
     compliance with Section 7(a), as to any transfer which may be involved in
     such division or combination, the Company shall execute and deliver a new
     Warrant or Warrants in exchange for the Warrant or Warrants to be divided
     or combined in accordance with such notice.

          (c) The Company shall prepare, issue and deliver at its own expense
     (other than transfer taxes) the new Warrant or Warrants under this
     Section 7.

          (d) The Company agrees to maintain, at its aforesaid office, books for
     the registration and the registration of transfer of the Warrants.

     8. No Rights as Shareholder until Exercise. This Warrant does not entitle
the holder hereof to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the
payment of the aggregate Exercise Price, the Warrant Shares so purchased shall
be and be deemed to be issued to such holder as the record owner of such shares
as of the close of business on the later of the date of such surrender or
payment.

     9. Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants
that upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant certificate or any
stock certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably

                                        3


satisfactory to it (which shall not include the posting of any bond), and upon
surrender and cancellation of such Warrant or stock certificate, if mutilated,
the Company will make and deliver a new Warrant or stock certificate of like
tenor and dated as of such cancellation, in lieu of such Warrant or stock
certificate.

     10. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the
taking of any action or the expiration of any right required or granted herein
shall be a Saturday, Sunday or a legal holiday, then such action may be taken or
such right may be exercised on the next succeeding day not a Saturday, Sunday or
legal holiday.

     11. Adjustments of Exercise Price and Number of Warrant Shares. (a) Stock
Splits, etc. The number and kind of securities purchasable upon the exercise of
this Warrant and the Exercise Price shall be subject to adjustment from time to
time upon the happening of any of the following. In case the Company shall (i)
pay a dividend in shares of Common Stock or make a distribution in shares of
Common Stock to holders of its outstanding Common Stock, (ii) subdivide its
outstanding shares of Common Stock into a greater number of shares of Common
Stock, (iii) combine its outstanding shares of Common Stock into a smaller
number of shares of Common Stock or (iv) issue any shares of its capital stock
in a reclassification of the Common Stock, then the number of Warrant Shares
purchasable upon exercise of this Warrant immediately prior thereto shall be
adjusted so that the holder of this Warrant shall be entitled to receive the
kind and number of Warrant Shares or other securities of the Company which he
would have owned or have been entitled to receive had such Warrant been
exercised in advance thereof. Upon each such adjustment of the kind and number
of Warrant Shares or other securities of the Company which are purchasable
hereunder, the holder of this Warrant shall thereafter be entitled to purchase
the number of Warrant Shares or other securities resulting from such adjustment
at an Exercise Price per Warrant Share or other security obtained by multiplying
the Exercise Price in effect immediately prior to such adjustment by the number
of Warrant Shares purchasable pursuant hereto immediately prior to such
adjustment and dividing by the number of Warrant Shares or other securities of
the Company resulting from such adjustment. An adjustment made pursuant to this
paragraph shall become effective immediately after the effective date of such
event retroactive to the record date, if any, for such event. (b)
Reorganization, Reclassification, Merger, Consolidation or Disposition of
Assets. In case the Company shall reorganize its capital, reclassify its capital
stock, consolidate or merge with or into another corporation (where the Company
is not the surviving corporation or where there is a change in or distribution
with respect to the Common Stock of the Company), or sell, transfer or otherwise
dispose of all or substantially all its property, assets or business to another
corporation and, pursuant to the terms of such reorganization, reclassification,
merger, consolidation or disposition of assets, shares of common stock of the
successor or acquiring corporation, or any cash, shares of stock or other
securities or property of any nature whatsoever (including warrants or other
subscription or purchase rights) in addition to or in lieu of common stock of
the successor or acquiring corporation ("Other Property"), are to be received by
or distributed to the holders of Common Stock of the Company, then Holder shall
have the right thereafter to receive, upon exercise of this Warrant, the number
of shares of common stock of the successor or acquiring corporation or of the
Company, if it is the surviving corporation, and Other Property receivable upon
or as a result of such reorganization, reclassification, merger, consolidation
or disposition of assets by a holder of the number of shares of Common Stock for
which this Warrant is exercisable immediately prior to such event. In case of
any such reorganization,

                                        4


reclassification, merger, consolidation or disposition of assets, the successor
or acquiring corporation (if other than the Company) shall expressly assume the
due and punctual observance and performance of each and every covenant and
condition of this Warrant to be performed and observed by the Company and all
the obligations and liabilities hereunder, subject to such modifications as may
be deemed appropriate (as determined in good faith by resolution of the Board of
Directors of the Company) in order to provide for adjustments of shares of
Common Stock for which this Warrant is exercisable which shall be as nearly
equivalent as practicable to the adjustments provided for in this Section 11.
For purposes of this Section 11, "common stock of the successor or acquiring
corporation" shall include stock of such corporation of any class which is not
preferred as to dividends or assets over any other class of stock of such
corporation and which is not subject to redemption and shall also include any
evidences of indebtedness, shares of stock or other securities which are
convertible into or exchangeable for any such stock, either immediately or upon
the arrival of a specified date or the happening of a specified event and any
warrants or other rights to subscribe for or purchase any such stock. The
foregoing provisions of this Section 11 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or disposition of
assets.

     12. Voluntary Adjustment by the Company. The Company may at any time during
the term of this Warrant, reduce the then current Exercise Price to any amount
and for any period of time deemed appropriate by the Board of Directors of the
Company.

     13. Notice of Adjustment. Whenever the number of Warrant Shares or number
or kind of securities or other property purchasable upon the exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Company shall
promptly mail by registered or certified mail, return receipt requested, to the
holder of this Warrant notice of such adjustment or adjustments setting forth
the number of Warrant Shares (and other securities or property) purchasable upon
the exercise of this Warrant and the Exercise Price of such Warrant Shares (and
other securities or property) after such adjustment, setting forth a brief
statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made. Such notice, in the absence of
manifest error, shall be conclusive evidence of the correctness of such
adjustment.

     14. Notice of Corporate Action. If at any time:

          (a) the Company shall take a record of the holders of its Common Stock
     for the purpose of entitling them to receive a dividend or other
     distribution, or any right to subscribe for or purchase any evidences of
     its indebtedness, any shares of stock of any class or any other securities
     or property, or to receive any other right, or

          (b) there shall be any capital reorganization of the Company, any
     reclassification or recapitalization of the capital stock of the Company or
     any consolidation or merger of the Company with, or any sale, transfer or
     other disposition of all or substantially all the property, assets or
     business of the Company to, another corporation or,

          (c) there shall be a voluntary or involuntary dissolution, liquidation
     or winding up of the Company;

                                        5


then, in any one or more of such cases, the Company shall give to Holder (i) at
least 30 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 30
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their shares of Common Stock for securities or other
property deliverable upon such disposition, dissolution, liquidation or winding
up. Each such written notice shall be sufficiently given if addressed to Holder
at the last address of Holder appearing on the books of the Company and
delivered in accordance with Section 16(d).

     15. Authorized Shares. The Company covenants that during the period the
Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any purchase rights under this Warrant. The Company
further covenants that its issuance of this Warrant shall constitute full
authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the Principal Market
upon which the Common Stock may be listed.

     The Company shall not by any action, including, without limitation,
amending its certificate of incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate to protect the rights of Holder
against impairment. Without limiting the generality of the foregoing, the
Company will (a) not increase the par value of any shares of Common Stock
receivable upon the exercise of this Warrant above the amount payable therefor
upon such exercise immediately prior to such increase in par value, (b) take all
such action as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and nonassessable shares of Common Stock
upon the exercise of this Warrant, and (c) use all commercially reasonable
efforts to obtain all such authorizations, exemptions or consents from any
public regulatory body having jurisdiction thereof as may be necessary to enable
the Company to perform its obligations under this Warrant.

     Upon the request of Holder, the Company will at any time during the period
this Warrant is outstanding acknowledge in writing, in form reasonably
satisfactory to Holder, the continuing validity of this Warrant and the
obligations of the Company hereunder.

                                        6


     Before taking any action which would cause an adjustment reducing the
current Exercise Price below the then par value, if any, of the shares of Common
Stock issuable upon exercise of the Warrants, the Company shall take any
corporate action which may be necessary in order that the Company may validly
and legally issue fully paid and non-assessable shares of such Common Stock at
such adjusted Exercise Price.

     Before taking any action which would result in an adjustment in the number
of shares of Common Stock for which this Warrant is exercisable or in the
Exercise Price, the Company shall obtain all such authorizations or exemptions
thereof, or consents thereto, as may be necessary from any public regulatory
body or bodies having jurisdiction thereof.

     16. Miscellaneous.

          (a) Jurisdiction. This Warrant shall be binding upon any successors or
     assigns of the Company. This Warrant shall constitute a contract under the
     laws of New York without regard to its conflict of law principles or rules,
     and be subject to arbitration pursuant to the terms set forth in the
     Purchase Agreement.

          (b) Restrictions. The holder hereof acknowledges that the Warrant
     Shares acquired upon the exercise of this Warrant, if not registered, will
     have restrictions upon resale imposed by state and federal securities laws.

          (c) Nonwaiver and Expenses. No course of dealing or any delay or
     failure to exercise any right hereunder on the part of Holder shall operate
     as a waiver of such right or otherwise prejudice Holder's rights, powers or
     remedies, notwithstanding all rights hereunder terminate on the Termination
     Date hereof. If the Company willfully fails to comply with any material
     provision of this Warrant, the Company shall pay to Holder such amounts as
     shall be sufficient to cover any costs and expenses including, but not
     limited to, reasonable attorneys' fees, including those of appellate
     proceedings, incurred by Holder in collecting any amounts due pursuant
     hereto or in otherwise enforcing any of its rights, powers or remedies
     hereunder.

          (d) Notices. Any notice, request or other document required or
     permitted to be given or delivered to the holder hereof by the Company
     shall be delivered in accordance with the notice provisions of the Purchase
     Agreement.

          (e) Limitation of Liability. No provision hereof, in the absence of
     affirmative action by Holder to purchase shares of Common Stock, and no
     enumeration herein of the rights or privileges of Holder hereof, shall give
     rise to any liability of Holder for the purchase price of any Common Stock
     or as a stockholder of the Company, whether such liability is asserted by
     the Company or by creditors of the Company.

          (f) Remedies. Holder, in addition to being entitled to exercise all
     rights granted by law, including recovery of damages, will be entitled to
     specific performance of its rights under this Warrant. The Company agrees
     that monetary damages would not be

                                        7


     adequate compensation for any loss incurred by reason of a breach by it of
     the provisions of this Warrant and hereby agrees to waive the defense in
     any action for specific performance that a remedy at law would be adequate.

          (g) Successors and Assigns. Subject to applicable securities laws,
     this Warrant and the rights and obligations evidenced hereby shall inure to
     the benefit of and be binding upon the successors of the Company and the
     successors and permitted assigns of Holder. The provisions of this Warrant
     are intended to be for the benefit of all Holders from time to time of this
     Warrant and shall be enforceable by any such Holder or holder of Warrant
     Shares.

          (h) Indemnification. The Company agrees to indemnify and hold harmless
     Holder from and against any liabilities, obligations, losses, damages,
     penalties, actions, judgments, suits, claims, costs, attorneys' fees,
     expenses and disbursements of any kind which may be imposed upon, incurred
     by or asserted against Holder in any manner relating to or arising out of
     any failure by the Company to perform or observe in any material respect
     any of its covenants, agreements, undertakings or obligations set forth in
     this Warrant; provided, however, that the Company will not be liable
     hereunder to the extent that any liabilities, obligations, losses, damages,
     penalties, actions, judgments, suits, claims, costs, attorneys' fees,
     expenses or disbursements are found in a final non-appealable judgment by a
     court to have resulted from Holder's negligence, bad faith or willful
     misconduct in its capacity as a stockholder or warrantholder of the
     Company.

          (i) Amendment. This Warrant may be modified or amended or the
     provisions hereof waived with the written consent of the Company and the
     Holder.

          (j) Severability. Wherever possible, each provision of this Warrant
     shall be interpreted in such manner as to be effective and valid under
     applicable law, but if any provision of this Warrant shall be prohibited by
     or invalid under applicable law, such provision shall be ineffective to the
     extent of such prohibition or invalidity, without invalidating the
     remainder of such provisions or the remaining provisions of this Warrant.

          (k) Headings. The headings used in this Warrant are for the
     convenience of reference only and shall not, for any purpose, be deemed a
     part of this Warrant.

                                       8


     IN WITNESS WHEREOF, the Company has caused this Warrant to be executed by
its officer thereunto duly authorized.
