                    To Purchase [      ] Shares of Common Stock of

                                 PURE Bioscience

THIS COMMON STOCK PURCHASE WARRANT CERTIFIES that, for value received,
_____________________ (the "Holder"), is entitled, upon the terms and subject to
the limitations on exercise and the conditions hereinafter set forth, at any
time on or before the close of business on the Termination Date (as defined
below) but not thereafter, to subscribe for and purchase from PURE Bioscience a

Stock"). The purchase price of each full share of Common Stock (the "Exercise
Price") under this Warrant shall be $6.00, subject to adjustment hereunder. The
Exercise Price and the number of Warrant Shares for which the Warrant is
exercisable shall be subject to adjustment as provided herein. As used herein

Purchase Agreement (the "Purchase Agreement"), dated October [ ], 2007, between
the Company and the purchasers signatory thereto.


<PAGE>





     1. Title to Warrant. Prior to the Termination Date and subject to
compliance with applicable laws and Section 7 of this Warrant, this Warrant and
all rights hereunder are transferable, in whole or in part, at the office or
agency of the Company by the Holder in person or by duly authorized attorney,
upon surrender of this Warrant together with the Assignment Form annexed hereto
properly endorsed. The transferee shall sign an investment letter in form and
substance reasonably satisfactory to the Company.

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

          (a) 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
     before the Termination Date by surrendering 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 at the address of such Holder
     appearing on the books of the Company) and paying the Exercise Price of the
     shares thereby purchased by wire transfer or cashier's check drawn on a
     United States bank or electing a cashless exercise pursuant to Section
     3(d), and the Holder shall be entitled to receive a certificate for the
     number of Warrant Shares so purchased. Certificates for shares purchased
     hereunder shall be delivered to the Holder within five (5) 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 the
     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 the Holder, if any,
     pursuant to Section 5 prior to the issuance of such shares, have been paid.
     "Trading Day" means a day on which the NASDAQ Stock Market is open for the
     transaction of business.

          (b) 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 Warrant Shares called for by
     this Warrant, which new Warrant shall in all other respects be identical
     with this Warrant.

          (c) If the Company fails to deliver to the Holder a certificate or
     certificates representing the Warrant Shares pursuant to Section 3(a) of
     this Warrant by the close of business on the fifth Trading Day after the
     date of exercise, then the Holder will have the right to rescind such
     exercise.


<PAGE>

          (d) If, but only if, at any time after one year from the date of
     issuance of this Warrant there is no effective Registration Statement
     registering the resale of the Warrant Shares by the Holder, 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 Warrant Shares
     equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

                  (A)     = the Closing Price on the Trading Day immediately
                          preceding the date of such election;

                  (B)     = the Exercise Price of this Warrant, as adjusted; and

                  (X)     = the number of Warrant Shares issuable upon exercise
                          of this Warrant in accordance with the terms of this
                          Warrant by means of a cash exercise rather than a
                          cashless exercise.

     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 such fraction multiplied by
the Exercise Price.

     5. Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares
shall be made without charge to the Holder 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 or in such name or names as may be
directed by the Holder; provided, however, that in the event certificates for
Warrant Shares are to be issued in a name other than the name of the Holder,
this Warrant when surrendered for exercise shall be accompanied by the
Assignment Form attached hereto duly executed by the Holder; 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 stockholder books or
records in any manner that prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

     7. Transfer, Division and Combination.

          (a) Subject to compliance with any applicable securities laws and the
     conditions set forth herein and in the Purchase Agreement, this Warrant and
     all rights hereunder are transferable, in whole or in part, 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 the 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 Warrant Shares without
     having a new Warrant issued.


<PAGE>

          (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 the 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.

          (e) If, at the time of the surrender of this Warrant in connection
     with any transfer of this Warrant, the transfer of this Warrant shall not
     be registered pursuant to an effective registration statement under the
     Securities Act and under applicable state securities or blue sky laws, the
     Company may require, as a condition of allowing such transfer (i) that the
     Holder or transferee of this Warrant, as the case may be, furnish to the
     Company a written opinion of counsel (which opinion shall be in form,
     substance and scope customary for opinions of counsel in comparable
     transactions) to the effect that such transfer may be made without
     registration under the Securities Act and under applicable state securities
     or blue sky laws, (ii) that the holder or transferee execute and deliver to
     the Company an investment letter in form and substance acceptable to the
     Company and (iii) that the transferee be an "accredited investor" as
     defined in Rule 501(a) promulgated under the Securities Act.

     8. No Rights as Shareholder until Exercise. This Warrant does not entitle
the Holder 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 (or election of a cashless exercise), 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.


<PAGE>

     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 or any stock
certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which, in
the case of the Warrant, 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. 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) declare a
dividend or other distribution in shares of Common Stock or other securities or
property of the Company to holders of its outstanding Common Stock, (ii)
subdivide its outstanding shares of Common Stock into a greater number of
shares, (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 shall be entitled to receive the kind and number of
Warrant Shares or other securities of the Company which it 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
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 that are purchasable
pursuant hereto immediately after 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.

     12. 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 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 the 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, 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 Warrant Shares for which this Warrant is exercisable which shall
be as nearly equivalent as practicable to the adjustments provided for in this
Section 12. For purposes of this Section 12, "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 12 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or disposition of
assets.


<PAGE>
     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
give notice thereof to the Holder, which notice shall state 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.

     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;


<PAGE>
then, in any one or more of such cases, the Company shall give to Holder (i) at
least 10 calendar 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
calendar 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 Warrant Shares 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 17(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 Trading Market upon
which the Common Stock may be listed.

     Except and to the extent as waived or consented to by the Holder, 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 as set forth in this
Warrant against impairment. Without limiting the generality of the foregoing,
the Company will (a) not increase the par value of any Warrant Shares 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
Warrant Shares upon the exercise of this Warrant, and (c) use 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.

     Before taking any action which would result in an adjustment in the number
of Warrant Shares 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.


<PAGE>

     16. Registration Rights. The Warrant Shares shall be entitled to the
registration rights as set forth in the Purchase Agreement. Such registration
rights are incorporated herein by this reference as if such provisions had been
set forth herein full.

     17. Miscellaneous.

          (a) Jurisdiction. All questions concerning the construction, validity,
     enforcement and interpretation of this Warrant shall be determined in
     accordance with the provisions of the Purchase Agreement.

          (b) Restrictions. The Holder 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. If the Company willfully and knowingly fails to comply with any
     provision of this Warrant, which results in any material damages to the
     Holder, 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 by the Company shall be
     delivered in accordance with the notice provisions of the Purchase
     Agreement; provided upon any permitted assignment of this Warrant, the
     assignee shall promptly provide the Company with its contact information.

          (e) Limitation of Liability. No provision hereof, in the absence of
     any affirmative action by Holder to exercise this Warrant or purchase
     Warrant Shares, and no enumeration herein of the rights or privileges of
     Holder, 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 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.


<PAGE>

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

          (i) 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.

          (j) 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.
