                             TECHNICLONE CORPORATION

         THIS CERTIFIES that ____________________ or any subsequent holder
hereof ("Holder"), has the right to purchase from TECHNICLONE CORPORATION a
Delaware corporation (the "Company"), up to _____________ fully paid and
nonassessable shares of the Company's common stock, $.001 par value per share
("Common Stock"), subject to adjustment as provided herein, at a price equal to
the Exercise Price as defined in Section 3 below, at any time beginning on the
Date of Issuance (defined below) and ending at 5:00 p.m., New York, New York
time, on January 6, 2005 (the "Exercise Period").

         Holder agrees with the Company that this Warrant to Purchase Common
Stock of Techniclone Corporation (this "Warrant") is issued and all rights
hereunder shall be held subject to all of the conditions, limitations and
provisions set forth herein.

         1. DATE OF ISSUANCE.

         This Warrant shall be deemed to be issued on _________, 2000 ("Date of
Issuance").

         2. EXERCISE.

<PAGE>

            (a) MANNER OF EXERCISE. During the Exercise Period, this Warrant may
be exercised as to all or any lesser number of full shares of Common Stock
covered hereby upon surrender of this Warrant, with the Exercise Form attached
hereto as EXHIBIT A (the "Exercise Form") duly completed and executed, together
with the full Exercise Price (as defined below) for each share of Common Stock
as to which this Warrant is exercised, at the office of the Company, at the
address, telephone number and fax number set forth on the signature page hereof,
or at such other office or agency as the Company may designate in writing, by
overnight mail, with an advance copy of the Exercise Form sent to the Company
and its Transfer Agent by facsimile (such surrender and payment of the Exercise
Price hereinafter called the "Exercise of this Warrant").

            (b) DATE OF EXERCISE. The "Date of Exercise" of the Warrant shall be
defined as the date that the advance copy of the completed and executed Exercise
Form is sent by facsimile to the Company, provided that the original Warrant and
Exercise Form are received by the Company as soon as practicable thereafter.
Alternatively, the Date of Exercise shall be defined as the date the original
Exercise Form is received by the Company, if Holder has not sent advance notice
by facsimile.

            (c) CANCELLATION OF WARRANT. This Warrant shall be canceled upon the
Exercise of this Warrant, and, as soon as practical after the Date of Exercise,
Holder shall be entitled to receive Common Stock for the number of shares
purchased upon such Exercise of this Warrant, and if this Warrant is not
exercised in full, Holder shall be entitled to receive a new Warrant (containing
terms identical to this Warrant) representing any unexercised portion of this
Warrant in addition to such Common Stock.

            (d) HOLDER OF RECORD. Each person in whose name any Warrant for
shares of Common Stock is issued shall, for all purposes, be deemed to be the
Holder of record of such shares on the Date of Exercise of this Warrant,
irrespective of the date of delivery of the Common Stock purchased upon the
Exercise of this Warrant. Nothing in this Warrant shall be construed as
conferring upon Holder any rights as a stockholder of the Company.

         3. PAYMENT OF WARRANT EXERCISE PRICE.

         The Exercise Price shall equal $.25 per share ("Exercise Price").

         Payment of the Exercise Price may be made by either of the following,
or a combination thereof, at the election of Holder:

            (i) CASH EXERCISE: cash, bank or cashiers check or wire transfer; or

            (ii) CASHLESS EXERCISE: The Holder, at its option, may exercise this
Warrant in a cashless exercise transaction under this subsection (ii) if and
only if, on the Date of Exercise, there is not then in effect a current
registration statement that covers the resale of the shares of Common Stock to
be issued upon exercise of this Warrant. In order to effect a Cashless Exercise,
the Holder shall, surrender this Warrant at the principal office of the Company
together with notice of cashless election, in which event the Company shall
issue Holder a number of shares of Common Stock computed using the following
formula:

                                       2
<PAGE>

                           X = Y (A-B)/A

where:   X = the number of shares of Common Stock to be issued to Holder.

         Y = the number of shares of Common Stock for which this Warrant
             is being exercised.

                  A = the Market Price of one (1) share of Common Stock (for
                  purposes of this Section 3(ii), the "Market Price" shall be
                  defined as the average closing price of the Common Stock for
                  the five (5) trading days prior to the Date of Exercise of
                  this Warrant (the "Average Closing Price"), as reported by the
                  National Association of Securities Dealers Automated Quotation
                  System ("Nasdaq") Small Cap Market, or if the Common Stock is
                  not traded on the Nasdaq Small Cap Market, the Average Closing
                  Price in any other over-the-counter market; provided, however,
                  that if the Common Stock is listed on a stock exchange, the
                  Market Price shall be the Average Closing Price on such
                  exchange for the five (5) trading days prior to the date of
                  exercise of the Warrants. If the Common Stock is/was not
                  traded during the five (5) trading days prior to the Date of
                  Exercise, then the closing price for the last publicly traded
                  day shall be deemed to be the closing price for any and all
                  (if applicable) days during such five (5) trading day period.

                  B = the Exercise Price.

For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is intended,
understood and acknowledged that the Common Stock issuable upon exercise of this
Warrant in a cashless exercise transaction shall be deemed to have been acquired
at the time this Warrant was issued. Moreover, it is intended, understood and
acknowledged that the holding period for the Common Stock issuable upon exercise
of this Warrant in a cashless exercise transaction shall be deemed to have
commenced on the date this Warrant was issued.

         4. TRANSFER AND REGISTRATION.

            (a) TRANSFER RIGHTS. Subject to the provisions of Section 8 of this
Warrant, this Warrant may be transferred on the books of the Company, in whole
or in part, in person or by attorney, upon surrender of this Warrant properly
completed and endorsed. This Warrant shall be canceled upon such surrender and,
as soon as practicable thereafter, the person to whom such transfer is made
shall be entitled to receive a new Warrant or Warrants as to the portion of this
Warrant transferred, and Holder shall be entitled to receive a new Warrant as to
the portion hereof retained.

            (b) REGISTRABLE SECURITIES. The Common Stock issuable upon the
exercise of this Warrant constitutes "Registrable Securities" under that certain
Registration Rights Agreement dated on or about January 6, 2000 between the
Company and certain investors and, accordingly, has the benefit of the
registration rights pursuant to that agreement.

         5. ANTI-DILUTION ADJUSTMENTS.

                                       3
<PAGE>

            (a) STOCK DIVIDEND. If the Company shall at any time declare a
dividend payable in shares of Common Stock, then Holder, upon Exercise of this
Warrant after the record date for the determination of holders of Common Stock
entitled to receive such dividend, shall be entitled to receive upon Exercise of
this Warrant, in addition to the number of shares of Common Stock as to which
this Warrant is exercised, such additional shares of Common Stock as such Holder
would have received had this Warrant been exercised immediately prior to such
record date and the Exercise Price will be proportionately adjusted.

            (b) RECAPITALIZATION OR RECLASSIFICATION. If the Company shall at
any time effect a recapitalization, reclassification or other similar
transaction of such character that the shares of Common Stock shall be changed
into or become exchangeable for a larger or smaller number of shares, then upon
the effective date thereof, the number of shares of Common Stock which Holder
shall be entitled to purchase upon Exercise of this Warrant shall be increased
or decreased, as the case may be, in direct proportion to the increase or
decrease in the number of shares of Common Stock by reason of such
recapitalization, reclassification or similar transaction, and the Exercise
Price shall be, in the case of an increase in the number of shares,
proportionally decreased and, in the case of decrease in the number of shares,
proportionally increased. The Company shall give Holder the same notice it
provides to holders of Common Stock of any transaction described in this Section
5(b).

            (c) DISTRIBUTIONS. If the Company shall at any time distribute for
no consideration to holders of Common Stock cash, evidences of indebtedness or
other securities or assets (other than cash dividends or distributions payable
out of earned surplus or net profits for the current or preceding year) then, in
any such case, Holder shall be entitled to receive, upon Exercise of this
Warrant, with respect to each share of Common Stock issuable upon such exercise,
the amount of cash or evidences of indebtedness or other securities or assets
which Holder would have been entitled to receive with respect to each such share
of Common Stock as a result of the happening of such event had this Warrant been
exercised immediately prior to the record date or other date fixing shareholders
to be affected by such event (the "Determination Date") or, in lieu thereof, if
the Board of Directors of the Company should so determine at the time of such
distribution, a reduced Exercise Price determined by multiplying the Exercise
Price on the Determination Date by a fraction, the numerator of which is the
result of such Exercise Price reduced by the value of such distribution
applicable to one share of Common Stock (such value to be determined by the
Board of Directors of the Company in its discretion) and the denominator of
which is such Exercise Price.

            (d) NOTICE OF CONSOLIDATION OR MERGER. In the event of a merger,
consolidation, exchange of shares, recapitalization, reorganization, 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 there
is a sale of all or substantially all the Company's assets (a "Corporate
Change"), then this Warrant shall be exerciseable into such class and type of
securities or other assets as Holder would have received had Holder exercised
this Warrant immediately prior to such Corporate Change; provided, however, that
Company may not affect any Corporate Change unless it first shall have given
thirty (30) days notice to Holder hereof of any Corporate Change.

                                       4
<PAGE>

            (e) EXERCISE PRICE ADJUSTED. As used in this Warrant, the term
"Exercise Price" shall mean the purchase price per share specified in Section 3
of this Warrant, until the occurrence of an event stated in subsection (a), (b)
or (c) of this Section 5, and thereafter shall mean said price as adjusted from
time to time in accordance with the provisions of said subsection. No such
adjustment under this Section 5 shall be made unless such adjustment would
change the Exercise Price at the time by $.01 or more; provided, however, that
all adjustments not so made shall be deferred and made when the aggregate
thereof would change the Exercise Price at the time by $.01 or more. No
adjustment made pursuant to any provision of this Section 5 shall have the net
effect of increasing the Exercise Price. The number of shares of Common Stock
subject hereto shall increase proportionately with each decrease in the Exercise
Price.

            (f) ADJUSTMENTS: ADDITIONAL SHARES, SECURITIES OR ASSETS. In the
event that at any time, as a result of an adjustment made pursuant to this
Section 5, Holder shall, upon Exercise of this Warrant, become entitled to
receive shares and/or other 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 5.

                                       5
<PAGE>

         6. 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,
Holder may purchase only a whole number of shares of Common Stock. If, on
Exercise of this Warrant, Holder would be entitled to a fractional share of
Common Stock or a right to acquire a fractional share of Common Stock, such
fractional share shall be disregarded and the number of shares of Common Stock
issuable upon exercise shall be the next higher number of shares.

         7. RESERVATION OF SHARES.

            The Company shall at all times reserve for issuance such number of
authorized and unissued shares of Common Stock (or other securities substituted
therefor as herein above provided) as shall be sufficient for the Exercise of
this Warrant and payment of the Exercise Price. The Company covenants and agrees
that upon the Exercise of this Warrant, all shares of Common Stock issuable upon
such exercise shall be duly and validly issued, fully paid, nonassessable and
not subject to preemptive rights, rights of first refusal or similar rights of
any person or entity.

         8. RESTRICTIONS ON TRANSFER.

            (a) REGISTRATION OR EXEMPTION REQUIRED. This Warrant has been issued
in a transaction exempt from the registration requirements of the Act by virtue
of Regulation D and exempt from state registration under applicable state laws.
The Warrant and the Common Stock issuable upon the Exercise of this Warrant may
not be pledged, transferred, sold or assigned except pursuant to an effective
registration statement or an exemption to the registration requirements of the
Act and applicable state laws.

            (b) ASSIGNMENT. If Holder can provide the Company with reasonably
satisfactory evidence that the conditions of (a) above regarding registration or
exemption have been satisfied, Holder may sell, transfer, assign, pledge or
otherwise dispose of this Warrant, in whole or in part. Holder shall deliver a
written notice to Company, substantially in the form of the Assignment attached
hereto as EXHIBIT B, indicating the person or persons to whom the Warrant shall
be assigned and the respective number of warrants to be assigned to each
assignee. The Company shall effect the assignment within ten (10) days, and
shall deliver to the assignee(s) designated by Holder a Warrant or Warrants of
like tenor and terms for the appropriate number of shares.

         9. BENEFITS OF THIS WARRANT.

            Nothing in this Warrant shall be construed to confer upon any person
other than the Company and Holder any legal or equitable right, remedy or claim
under this Warrant and this Warrant shall be for the sole and exclusive benefit
of the Company and Holder.

                                       6

         10. APPLICABLE LAW.

            This Warrant is issued under and shall for all purposes be governed
by and construed in accordance with the laws of the state of Delaware, without
giving effect to conflict of law provisions thereof.

         11. LOSS 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 or security reasonably satisfactory to the Company,

shall execute and deliver a new Warrant of like tenor and date.
