Issue Date:  March 10, 2005                                    Warrant No.  __


      THIS CERTIFIES that _______________________ or any subsequent holder
hereof (the "Holder"), has the right to purchase from DEEP WELL OIL & GAS, INC.,
a Nevada corporation (the "Company"), up to [________] fully paid and
nonassessable shares of the Company's common stock, par value $0.001 per share
(the "Common Stock"), subject to adjustment as provided herein, at a price per
share equal to the Exercise Price (as defined below), at any time and from time
to time beginning on the date on which this Warrant is originally issued (the
"Issue Date") and ending at 6:00 p.m., eastern time, on the date that is the
fifth (5th) anniversary of the Issue Date (or, if such date is not a Business
Day, on the Business Day immediately following such date) (the "Expiration
Date"). This Warrant is issued pursuant to a Securities Purchase Agreement,
dated as of March 10, 2005 (the "Securities Purchase Agreement"). Capitalized
terms used herein and not otherwise defined shall have the respective meanings
set forth in the Securities Purchase Agreement.

      1. Exercise.

      (a) Right to Exercise; Exercise Price. The Holder shall have the right to
exercise this Warrant at any time and from time to time during the period
beginning on the Issue Date and ending on the Expiration Date as to all or any
part of the shares of Common Stock covered hereby (the "Warrant Shares"). The


                                       12
<PAGE>

"Exercise Price" for each Warrant Share purchased by the Holder upon the
exercise of this Warrant shall be equal to fifty cent ($0.50), subject to
adjustment for the events specified in Section 6 below.

      (b) Exercise Notice. In order to exercise this Warrant, the Holder shall
send to the Company by facsimile transmission, at any time prior to 6:00 p.m.,
eastern time, on the Business Day on which the Holder wishes to effect such
exercise (the "Exercise Date"), (i) a notice of exercise in substantially the
form attached hereto as Exhibit A (the "Exercise Notice"), and (ii) a copy of
the original Warrant, and, in the case of a Cash Exercise (as defined below),
the Holder shall pay the Exercise Price to the Company by wire transfer of
immediately available funds. The Exercise Notice shall state the name or names
in which the shares of Common Stock that are issuable on such exercise shall be
issued. In the case of a dispute between the Company and the Holder as to the
calculation of the Exercise Price or the number of Warrant Shares issuable
hereunder (including, without limitation, the calculation of any adjustment
pursuant to Section 6 below), the Company shall issue to the Holder the number
of Warrant Shares that are not disputed within the time periods specified in
Section 2 below and shall submit the disputed calculations to a certified public
accounting firm of national reputation (other than the Company's regularly
retained accountants) within two (2) Business Days following the date on which
the Holder's Exercise Notice is delivered to the Company. The Company shall
cause such accountant to calculate the Exercise Price and/or the number of
Warrant Shares issuable hereunder and to notify the Company and the Holder of
the results in writing no later than three (3) Business Days following the day
on which such accountant received the disputed calculations (the "Dispute
Procedure"). Such accountant's calculation shall be deemed conclusive absent
manifest error. The fees of any such accountant shall be borne by the party
whose calculations were most at variance with those of such accountant.

      (c) Holder of Record. The Holder shall, for all purposes, be deemed to
have become the holder of record of the Warrant Shares specified in an Exercise
Notice on the Exercise Date specified therein, irrespective of the date of
delivery of such Warrant Shares. Except as specifically provided herein, nothing
in this Warrant shall be construed as conferring upon the Holder hereof any
rights as a stockholder of the Company prior to the Exercise Date.

      (d) Cancellation of Warrant. This Warrant shall be canceled upon its
exercise in full and, if this Warrant is exercised in part, the Company shall,
at the time that it delivers Warrant Shares to the Holder pursuant to such
exercise as provided herein, issue a new warrant, and deliver to the Holder a
certificate representing such new warrant, with terms identical in all respects
to this Warrant (except that such new warrant shall be exercisable into the
number of shares of Common Stock with respect to which this Warrant shall remain
unexercised); provided, however, that the Holder shall be entitled to exercise
all or any portion of such new warrant at any time following the time at which
this Warrant is exercised, regardless of whether the Company has actually issued
such new warrant or delivered to the Holder a certificate therefor.

      2. Delivery of Warrant Shares Upon Exercise. Upon receipt of a fax copy of
an Exercise Notice pursuant to Section 1 above, the Company shall, (A) in the
case of a Cash Exercise, no later than the close of business on the later to
occur of (i) the third (3rd) Business Day following the Exercise Date specified
in such Exercise Notice and (ii) such later date on which the Company shall have
received payment of the Exercise Price, (B) in the case of a Cashless Exercise
(as defined below), no later than the close of business on the third (3rd)


                                      -2-
<PAGE>

Business Day following the Exercise Date specified in such Exercise Notice, and
(C) with respect to Warrant Shares that are the subject of a Dispute Procedure,
the close of business on the third (3rd) Business Day following the
determination made pursuant to Section 1(b) (each of the dates specified in (A),
(B) or (C) being referred to as a "Delivery Date"), issue and deliver or caused
to be delivered to the Holder the number of Warrant Shares as shall be
determined as provided herein. The Company shall effect delivery of Warrant
Shares to the Holder, as long as the Company's designated transfer agent (the
"Transfer Agent") participates in the Depository Trust Company ("DTC") Fast
Automated Securities Transfer program ("FAST") and no restrictive legend is
required pursuant to the terms of this Warrant or the Securities Purchase
Agreement, by crediting the account of the Holder or its nominee at DTC (as
specified in the applicable Exercise Notice) with the number of Warrant Shares
required to be delivered, no later than the close of business on such Delivery
Date. In the event that the Transfer Agent is not a participant in FAST or if
the Holder so specifies in a Exercise Notice or otherwise in writing on or
before the Exercise Date, the Company shall effect delivery of Warrant Shares by
delivering to the Holder or its nominee physical certificates representing such
Warrant Shares, no later than the close of business on such Delivery Date.
Warrant Shares delivered to the Holder shall not contain any restrictive legend
unless such legend is required pursuant to the terms of the Securities Purchase
Agreement.

      3. Failure to Deliver Warrant Shares.

      (a) In the event that the Company fails for any reason to deliver to the
Holder the number of Warrant Shares specified in the applicable Exercise Notice
on or before the Delivery Date therefor (an "Exercise Default"), the Company
shall pay to the Holder payments ("Exercise Default Payments") in the amount of
(i) (N/365) multiplied by (ii) the aggregate Exercise Price of the Warrant
Shares which are the subject of such Exercise Default multiplied by (iii) the
lower of twelve percent (12%) per annum and the maximum rate permitted by
applicable law (the "Default Interest Rate"), where "N" equals the number of
days elapsed between the original Delivery Date of such Warrant Shares and the
date on which all of such Warrant Shares are issued and delivered to the Holder.
Cash amounts payable hereunder shall be paid on or before the fifth (5th)
Business Day of each calendar month following the calendar month in which such
amount has accrued.

      (b) In the event of an Exercise Default, the Holder may, upon written
notice to the Company (an "Exercise Default Notice"), regain on the date of such
notice the rights of the Holder under the exercised portion of this Warrant that
is the subject of such Exercise Default. In the event of such Exercise Default
and delivery of an Exercise Default Notice, the Holder shall retain all of the
Holder's rights and remedies with respect to the Company's failure to deliver
such Warrant Shares (including without limitation the right to receive the cash
payments specified in Section 3(a) above).

      (c) The Holder's rights and remedies hereunder are cumulative, and no
right or remedy is exclusive of any other. In addition to the amounts specified
herein, the Holder shall have the right to pursue all other remedies available
to it at law or in equity (including, without limitation, a decree of specific
performance and/or injunctive relief). Nothing herein shall limit the Holder's
right to pursue actual damages for the Company's failure to issue and deliver
Warrant Shares on the applicable Delivery Date (including, without limitation,


                                      -3-
<PAGE>

damages relating to any purchase of Common Stock by the Holder to make delivery
on a sale effected in anticipation of receiving Warrant Shares upon exercise,
such damages to be in an amount equal to (A) the aggregate amount paid by the
Holder for the Common Stock so purchased minus (B) the aggregate amount of net
proceeds, if any, received by the Holder from the sale of the Warrant Shares
issued by the Company pursuant to such exercise).

      4. Exercise Limitations. In no event shall a Holder be permitted to
exercise this Warrant, or part hereof, if, upon such exercise, the number of
shares of Common Stock beneficially owned by the Holder (other than shares which
would otherwise be deemed beneficially owned except for being subject to a
limitation on conversion or exercise analogous to the limitation contained in
this Section 4), would exceed 4.99% of the number of shares of Common Stock then
issued and outstanding. As used herein, beneficial ownership shall be determined
in accordance with Section 13(d) of the Securities Exchange Act of 1934, as
amended, and the rules thereunder. To the extent that the limitation contained
in this Section 4 applies, the submission of an Exercise Notice by the Holder
shall be deemed to be the Holder's representation that this Warrant is
exercisable pursuant to the terms hereof and the Company shall be entitled to
rely on such representation without making any further inquiry as to whether
this Section 4 applies. Nothing contained herein shall be deemed to restrict the
right of a Holder to exercise this Warrant, or part thereof, at such time as
such exercise will not violate the provisions of this Section 4. This Section 4
may not be amended unless such amendment is approved by the holders of a
majority of the Common Stock then outstanding; provided, however, that the
limitations contained in this Section 4 shall cease to apply (x) upon sixty (60)
days' prior written notice from the Holder to the Company, or (y) immediately
upon written notice from the Holder to the Company at any time after the public
announcement or other disclosure of a Major Transaction (as defined below) or a
Change of Control. For purposes hereof, "Change of Control" means the existence
or occurrence of any of the following: (a) the sale, conveyance or disposition
of all or substantially all of the assets of the Company; (b) the effectuation
of a transaction or series of transactions in which more than fifty percent
(50%) of the voting power of the Company is disposed of; (c) the consolidation,
merger or other business combination of the Company with or into any other
entity, immediately following which the prior stockholders of the Company fail
to own, directly or indirectly, at least fifty percent (50%) of the surviving
entity; (d) a transaction or series of transactions in which any Person or group
acquires more than fifty percent (50%) of the voting equity of the Company; and
(e) the individuals serving on the Board of Directors as of the Closing Date do
not at any time constitute at least a majority of the Board of Directors of the
Company.

      5. Payment of the Exercise Price; Cashless Exercise. The Holder may pay
the Exercise Price in either of the following forms or, at the election of
Holder, a combination thereof:

      (a) through a cash exercise (a "Cash Exercise") by delivering immediately
available funds, or


                                      -4-
<PAGE>

      (b) if, for any reason, an effective Registration Statement is not
available for the resale of all of the Warrant Shares issuable hereunder at the
time an Exercise Notice is delivered to the Company, through a cashless exercise
(a "Cashless Exercise"), as hereinafter provided. The Holder may effect a
Cashless Exercise by surrendering this Warrant to the Company and noting on the
Exercise Notice that the Holder wishes to effect a Cashless Exercise, upon which
the Company shall issue to the Holder the number of Warrant Shares determined as
follows:

            X = Y x (A-B)/A

where:      X = the  number  of  Warrant  Shares  to be issued to the Holder;

            Y = the number of Warrant Shares with respect to which this
            Warrant is being exercised;

            A = the Market Price as of the Exercise Date; and

            B = the Exercise Price.

For purposes of Rule 144, it is intended and acknowledged that the Warrant
Shares issued in a Cashless Exercise transaction shall be deemed to have been
acquired by the Holder, and the holding period for the Warrant Shares required
by Rule 144 shall be deemed to have been commenced, on the Issue Date.

      6. Anti-Dilution Adjustments; Distributions; Other Events. The Exercise
Price and the number of Warrant Shares issuable hereunder shall be subject to
adjustment from time to time as provided in this Section 6. In the event that
any adjustment of the Exercise Price required herein results in a fraction of a
cent, the Exercise Price shall be rounded up or down to the nearest one
hundredth of a cent.

      (a) Subdivision or Combination of Common Stock. If the Company, at any
time after the Issue Date, subdivides (by any stock split, stock dividend,
recapitalization, reorganization, reclassification or otherwise) the outstanding
shares of Common Stock into a greater number of shares, then effective upon the
close of business on the record date for effecting such subdivision, the
Exercise Price in effect immediately prior to such subdivision will be
proportionately reduced. If the Company, at any time after the Issue Date,
combines (by reverse stock split, recapitalization, reorganization,
reclassification or otherwise) the outstanding shares of Common Stock into a
smaller number of shares, then, effective upon the close of business on the
record date for effecting such combination, the Exercise Price in effect
immediately prior to such combination will be proportionally increased.

      (b) Distributions. If, at any time after the Issue Date, the Company
declares or makes any distribution of cash or any other assets (or rights to
acquire such assets) to holders of Common Stock, as a partial liquidating
dividend or otherwise, including without limitation any dividend or distribution
to the Company's stockholders in shares (or rights to acquire shares) of capital
stock of a subsidiary) (a "Distribution"), the Company shall deliver written
notice of such Distribution (a "Distribution Notice") to the Holder at least
thirty (30) days prior to the earlier to occur of (i) the record date for
determining stockholders entitled to such Distribution (the "Record Date") and
(ii) the date on which such Distribution is made (the "Distribution Date") (the
earlier of such dates being referred to as the "Determination Date"). Within ten
(10) days following receipt of a Distribution Notice, the Holder shall notify
the Company whether the Holder has elected (A) to receive, upon any exercise of


                                      -5-
<PAGE>

this Warrant after the Determination Date, the same amount and type of assets
being distributed in such Distribution as though the Holder were, on the
Determination Date, a holder of a number of shares of Common Stock into which
this Warrant is exercisable as of such Determination Date (such number of shares
to be determined at the Exercise Price then in effect and without giving effect
to any limitations on such exercise) or (B) upon any exercise of this Warrant on
or after the Determination Date, to reduce the Exercise Price applicable to such
exercise by reducing the Exercise Price in effect on the Business Day
immediately preceding the Determination Date by an amount equal to the fair
market value of the assets to be distributed divided by the number of shares of
Common Stock as to which such Distribution is to be made, such fair market value
to be reasonably determined in good faith by the Company's Board of Directors.
If the Holder does not notify the Company of its election pursuant to the
preceding sentence on or before the tenth (10th) day following receipt of a
Distribution Notice delivered in accordance with this paragraph (b), the Holder
shall be deemed to have elected clause (A) of the preceding sentence; and if the
Company does not deliver a Distribution Notice within the time frames specified
above, the Holder shall have the right to choose either clause (A) or clause (B)
of the preceding sentence at any time following the date on which Holder's
receives notice or otherwise becomes aware of the Distribution.

      (c) Dilutive Issuances. If, at any time after the Issue Date, the Company
issues or sells, or in accordance with paragraph (d) below, is deemed to have
issued or sold, any shares of Common Stock for a price per share less than the
Exercise Price on the date of such issuance or sale (a "Dilutive Issuance"),
then the Exercise Price shall be adjusted to equal such lower price. No
adjustment shall be made pursuant hereto if such adjustment would result in an
increase in the Exercise Price.

      (d) Effect On Exercise Price Of Certain Events. For purposes of
determining the adjusted Exercise Price under paragraph (c) above, the following
will be applicable:

                  (A) Issuance Of Purchase Rights. If the Company issues or
      sells any Purchase Rights, whether or not immediately exercisable, and the
      price per share for which Common Stock is issuable upon the exercise of
      such Purchase Rights (and the price of any conversion of Convertible
      Securities, if applicable) is less than the Exercise Price in effect on
      the date of issuance or sale of such Purchase Rights, then the maximum
      total number of shares of Common Stock issuable upon the exercise of all
      such Purchase Rights (assuming full conversion, exercise or exchange of
      Convertible Securities, if applicable) shall, as of the date of the
      issuance or sale of such Purchase Rights, be deemed to be outstanding and
      to have been issued and sold by the Company for such price per share. For
      purposes of the preceding sentence, the "price per share for which Common
      Stock is issuable upon the exercise of such Purchase Rights" shall be
      determined by dividing (x) the total amount, if any, received or
      receivable by the Company as consideration for the issuance or sale of all
      such Purchase Rights, plus the minimum aggregate amount of additional
      consideration, if any, payable to the Company upon the exercise of all
      such Purchase Rights, plus, in the case of Convertible Securities issuable
      upon the exercise of such Purchase Rights, the minimum aggregate amount of
      additional consideration payable upon the conversion, exercise or exchange
      thereof (determined in accordance with the calculation method set forth in
      subparagraph (B) below) at the time such Convertible Securities first
      become convertible, exercisable or exchangeable, by (y) the maximum total


                                      -6-
<PAGE>

      number of shares of Common Stock issuable upon the exercise of all such
      Purchase Rights (assuming full conversion, exercise or exchange of
      Convertible Securities, if applicable). No further adjustment to the
      Exercise Price shall be made upon the actual issuance of such Common Stock
      upon the exercise of such Purchase Rights or upon the conversion, exercise
      or exchange of Convertible Securities issuable upon exercise of such
      Purchase Rights.

                  (B) Issuance Of Convertible Securities. If the Company issues
      or sells any Convertible Securities, whether or not immediately
      convertible, exercisable or exchangeable, and the price per share for
      which Common Stock is issuable upon such conversion, exercise or exchange
      is less than the Exercise Price in effect on the date of issuance or sale
      of such Convertible Securities, then the maximum total number of shares of
      Common Stock issuable upon the conversion, exercise or exchange of all
      such Convertible Securities shall, as of the date of the issuance or sale
      of such Convertible Securities, be deemed to be outstanding and to have
      been issued and sold by the Company for such price per share. If the
      Convertible Securities so issued or sold do not have a fluctuating
      conversion or exercise price or exchange ratio, then for the purposes of
      the immediately preceding sentence, the "price per share for which Common
      Stock is issuable upon such conversion, exercise or exchange" shall be
      determined by dividing (x) the total amount, if any, received or
      receivable by the Company as consideration for the issuance or sale of all
      such Convertible Securities, plus the minimum aggregate amount of
      additional consideration, if any, payable to the Company upon the
      conversion, exercise or exchange thereof (determined in accordance with
      the calculation method set forth in this subparagraph (B)), by (y) the
      maximum total number of shares of Common Stock issuable upon the exercise,
      conversion or exchange of all such Convertible Securities. If the
      Convertible Securities so issued or sold have a fluctuating conversion or
      exercise price or exchange ratio (a "Variable Rate Convertible Security"),
      then for purposes of the first sentence of this subparagraph (B), the
      "price per share for which Common Stock is issuable upon such conversion,
      exercise or exchange" shall be deemed to be the lowest price per share
      which would be applicable (assuming all holding period and other
      conditions to any discounts contained in such Variable Rate Convertible
      Security have been satisfied) if the conversion price of such Variable
      Rate Convertible Security on the date of issuance or sale thereof were
      seventy-five percent (75%) of the actual conversion price on such date
      (the "Assumed Variable Market Price"), and, further, if the conversion
      price of such Variable Rate Convertible Security at any time or times
      thereafter is less than or equal to the Assumed Variable Market Price last
      used for making any adjustment under this paragraph (c) with respect to
      any Variable Rate Convertible Security, the Exercise Price in effect at
      such time shall be readjusted to equal the Exercise Price which would have
      resulted if the Assumed Variable Market Price at the time of issuance of
      the Variable Rate Convertible Security had been seventy-five percent (75%)
      of the actual conversion price of such Variable Rate Convertible Security
      existing at the time of the adjustment required by this sentence;
      provided, however, that if the conversion or exercise price or exchange
      ratio of a Convertible Security may fluctuate solely as a result of
      provisions designed to protect against dilution, such Convertible Security
      shall not be deemed to be a Variable Rate Convertible Security. No further
      adjustment to the Exercise Price shall be made upon the actual issuance of
      such Common Stock upon conversion, exercise or exchange of such
      Convertible Securities.


                                      -7-
<PAGE>

                  (C) Change In Option Price Or Conversion Rate. If, following
      an adjustment to the Exercise Price upon the issuance of Purchase Rights
      or Convertible Securities pursuant to a Dilutive Issuance, there is a
      change at any time in (x) the amount of additional consideration payable
      to the Company upon the exercise of any Purchase Rights; (y) the amount of
      additional consideration, if any, payable to the Company upon the
      conversion, exercise or exchange of any Convertible Securities; or (z) the
      rate at which any Convertible Securities are convertible into or
      exercisable or exchangeable for Common Stock (in each such case, other
      than under or by reason of provisions designed to protect against
      dilution), then in any such case, the Exercise Price in effect at the time
      of such change shall be readjusted to the Exercise Price which would have
      been in effect at such time had such Purchase Rights or Convertible
      Securities still outstanding provided for such changed additional
      consideration or changed conversion, exercise or exchange rate, as the
      case may be, at the time initially issued or sold.

                  (D) Calculation Of Consideration Received. If any Common
      Stock, Purchase Rights or Convertible Securities are issued or sold for
      cash, the consideration received therefor will be the amount received by
      the Company therefore. In case any Common Stock, Purchase Rights or
      Convertible Securities are issued or sold for a consideration part or all
      of which shall be other than cash, including in the case of a strategic or
      similar arrangement in which the other entity will provide services to the
      Company, purchase services from the Company or otherwise provide
      intangible consideration to the Company, the amount of the consideration
      other than cash received by the Company (including the net present value
      of the consideration expected by the Company for the provided or purchased
      services) shall be the fair market value of such consideration, except
      where such consideration consists of publicly traded securities, in which
      case the amount of consideration received by the Company will be the
      Market Price thereof on the date of receipt. In case any Common Stock,
      Purchase Rights or Convertible Securities are issued in connection with
      any merger or consolidation in which the Company is the surviving
      corporation, the amount of consideration therefor will be deemed to be the
      fair market value of such portion of the net assets and business of the
      non-surviving corporation as is attributable to such Common Stock,
      Purchase Rights or Convertible Securities, as the case may be. The
      independent members of the Company's Board of Directors shall calculate
      reasonably and in good faith, using standard commercial valuation methods
      appropriate for valuing such assets, the fair market value of any
      consideration other than cash or securities.

                  (E) Issuances Without Consideration Pursuant to Existing
      Securities. If the Company issues (or becomes obligated to issue) shares
      of Common Stock pursuant to any anti-dilution or similar adjustments
      (other than as a result of stock splits, stock dividends and the like)
      contained in any Convertible Securities or Purchase Rights outstanding as
      of the date hereof, then all shares of Common Stock so issued shall be
      deemed to have been issued for no consideration.

      (e) Exceptions To Adjustment Of Exercise Price. Notwithstanding the
foregoing, no adjustment to the Exercise Price shall be made pursuant to
paragraph (c) above upon the issuance of any Excluded Securities. For purposes
hereof, "Excluded Securities" means (I) securities purchased under the
Securities Purchase Agreement; (II) securities issued upon exercise of the


                                      -8-
<PAGE>

Warrants; (III) shares of Common Stock issuable or issued to (x) employees,
consultants or directors from time to time upon the exercise of options, in such
case granted or to be granted in the discretion of the Board of Directors
pursuant to one or more stock option plans or restricted stock plans in effect
as of the Issue Date or adopted after the Issue Date by the independent members
of the Board of Directors with substantially the same terms as such plans in
effect as of the Issue Date, or (y) vendors pursuant to warrants to purchase
Common Stock that are outstanding on the date hereof or issued hereafter,
provided such issuances are approved by the Board of Directors; (IV) shares of
Common Stock issued in connection with a commercial lending transaction with a
federally-insured financial institution that is approved by the independent
members of the Board of Directors, provided that the fair market value of such
shares does not exceed ten percent (10%) of the amount borrowed; (V) shares of
Common Stock issued in connection with any stock split, stock dividend or
recapitalization of the Company; (VI) shares of Common Stock issued in
connection with the acquisition by the Company of any corporation or other
entity occurring after the Effective Date, provided that a fairness opinion with
respect to such acquisition is rendered by an investment bank of national
recognition; (VII) shares of Common Stock issued in connection with any
Convertible Securities or Purchase Rights outstanding on the date hereof and
disclosed in a schedule to the Securities Purchase Agreement; and (VIII) shares
issued to Persons with whom the Company is entering into a joint venture,
strategic alliance or other commercial relationship in connection with the
operation of the Company's business and not in connection with a transaction the
purpose of which is to raise equity capital.

      (f) Notice Of Adjustments. Upon the occurrence of one or more adjustments
or readjustments of the Exercise Price pursuant to paragraph (c) above or any
change in the number or type of stock, securities and/or other property issuable
upon exercise of this Warrant, the Company, at its expense, shall promptly
compute such adjustment or readjustment or change and prepare and furnish to the
Holder a notice (an "Adjustment Notice") setting forth such adjustment or
readjustment or change and showing in detail the facts upon which such
adjustment or readjustment or change is based, and, on or before the time that
it delivers an Adjustment Notice, publicly disclose the contents thereof. The
failure of the Company to deliver an Adjustment Notice shall not affect the
validity of any such adjustment.

      (g) Major Transactions. In the event of a merger, consolidation, business
combination, tender offer, exchange of shares, recapitalization, reorganization,
redemption or other similar event, as a result of which shares of Common Stock
shall be changed into the same or a different number of shares of the same or
another class or classes of stock or securities or other assets of the Company
or another entity or the Company shall sell all or substantially all of its
assets (each of the foregoing being a "Major Transaction"), the Company will
give the Holder at least twenty (20) Trading Days written notice prior to the
earlier of (x) the closing or effectiveness of such Major Transaction and (y)
the record date for the receipt of such shares of stock or securities or other
assets. In the event of a Major Transaction, the Holder shall be permitted to
either (i) require the Company to repurchase this Warrant for an amount to the
value of this Warrant calculated pursuant to the Black-Scholes pricing model or
(ii) exercise this Warrant in whole or in part at any time prior to the record
date for the receipt of such consideration and shall be entitled to receive, for
each share of Common Stock issuable to Holder upon such exercise, the same per
share consideration payable to the other holders of Common Stock in connection
with such Major Transaction. If and to the extent that the Holder retains any


                                      -9-
<PAGE>

portion of this Warrant following such record date, the Company will cause the
surviving or, in the event of a sale of assets, purchasing entity, as a
condition precedent to such Major Transaction, to assume the obligations of the
Company under this Warrant, with such adjustments to the Exercise Price and the
securities covered hereby as may be necessary in order to preserve the economic
benefits of this Warrant to the Holder.

      (h) Adjustments; Additional Shares, Securities or Assets. In the event
that at any time, as a result of an adjustment made pursuant to this Section 6,
the Holder of this Warrant shall, upon exercise of this Warrant, become entitled
to receive securities or assets (other than Common Stock) then, wherever
appropriate, all references herein to shares of Common Stock shall be deemed to
refer to and include such shares and/or other securities or assets; and
thereafter the number of such shares and/or other securities or assets shall be
subject to adjustment from time to time in a manner and upon terms as nearly
equivalent as practicable to the provisions of this Section 6. Any adjustment
made herein that results in a decrease in the Exercise Price shall also effect a
proportional increase in the number of shares of Common Stock into which this
Warrant is exercisable.

      7. Fractional Interests.

            No fractional shares or scrip representing fractional shares shall
be issuable upon the exercise of this Warrant, but on exercise of this Warrant,
the Holder hereof may purchase only a whole number of shares of Common Stock.
If, on exercise of this Warrant, the Holder hereof would be entitled to a
fractional share of Common Stock or a right to acquire a fractional share of
Common Stock, the Company shall, in lieu of issuing any such fractional share,
pay to the Holder an amount in cash equal to the product resulting from
multiplying such fraction by the Market Price as of the Exercise Date.

      8. Transfer of this Warrant.

            The Holder may sell, transfer, assign, pledge or otherwise dispose
of this Warrant, in whole or in part, as long as such sale or other disposition
is made pursuant to an effective registration statement or an exemption from the
registration requirements of the Securities Act. Upon such transfer or other
disposition (other than a pledge), the Holder shall deliver this Warrant to the
Company together with a written notice to the Company, substantially in the form
of the Transfer Notice attached hereto as Exhibit B (the "Transfer Notice"),
indicating the person or persons to whom this Warrant shall be transferred and,
if less than all of this Warrant is transferred, the number of Warrant Shares to
be covered by the part of this Warrant to be transferred to each such person.
Within three (3) Business Days of receiving a Transfer Notice and the original
of this Warrant, the Company shall deliver to the each transferee designated by
the Holder a Warrant or Warrants of like tenor and terms for the appropriate
number of Warrant Shares and, if less than all this Warrant is transferred,
shall deliver to the Holder a Warrant for the remaining number of Warrant
Shares.

Holder of this Warrant and nothing in this Warrant shall be construed to confer
upon any person other than the Holder of this Warrant any legal or equitable
right, remedy or claim hereunder.

      10. Loss, theft, destruction or mutilation of Warrant.

            Upon receipt by the Company of evidence of the loss, theft,
destruction or mutilation of this Warrant, and (in the case of loss, theft or
destruction) of indemnity reasonably satisfactory to the Company, and upon
surrender of this Warrant, if mutilated, the Company shall execute and deliver a
