                       REGULATION D SUBSCRIPTION AGREEMENT

         THE SECURITIES OFFERED HEREBY HAVE NOT BEEN REGISTERED WITH THE
         SECURITIES AND EXCHANGE COMMISSION OR ANY STATE OR OTHER SECURITIES
         AUTHORITIES. THEY MAY NOT BE SOLD OR TRANSFERRED EXCEPT PURSUANT TO AN
         EFFECTIVE REGISTRATION STATEMENT OR AN EXEMPTION FROM THE REGISTRATION
         REQUIREMENTS OF THE FEDERAL AND STATE SECURITIES LAWS.

         THIS SUBSCRIPTION AGREEMENT DOES NOT CONSTITUTE AN OFFER TO SELL, OR A

         THIS REGULATION D SUBSCRIPTION AGREEMENT (this "Agreement") is made as
of the 6th day of January, 2000, by and between Techniclone Corporation, a
corporation duly incorporated and existing under the laws of the State of

Agreement ("Subscriber").

         THE PARTIES HEREBY AGREE AS FOLLOWS:

         This Agreement is executed by Subscriber in connection with the offer
(the "Offering") by the Company and the purchase by Subscriber of "Units," where
each "Unit" consists of one share of the Company's Common Stock (collectively
referred to as the "Unit Shares") and a warrant ("Warrants") to purchase Common
Stock upon the terms set forth herein and in the Warrants. The Units are being
offered at a purchase price per share that is equal to $0.25, with an initial
offering amount of up to $600,000. The solicitation of this subscription and, if
accepted by the Company, the offer and sale of the Units are being made in

reliance upon the provisions of Regulation D ("Regulation D") promulgated under
the Securities Act of 1933, as amended (the "Act"). The Unit Shares and the

collectively as the "Securities."

         Subscribers shall have an option (the "Option") to purchase, within
sixty (60) days from the Closing Date (defined in Section 4.12) of the Offering
(the "Option Exercise Date"), up to an additional $300,000 of Units (the
"Optional Tranche") with the amount to be divided equally between Subscribers
under the same terms (including but not limited to the same Unit Price and the
same Warrant Exercise Price) as this Offering. The Option may be exercised by
each Subscriber by paying to the Company the purchase price for such additional
Units on or before the Option Exercise Date. Concurrently with the Closing of
the Option, the Company and the Subscriber shall enter into an agreement
equivalent to this Agreement with respect to the Optional Tranche.

any thereof and each other person, if any, who controls any of the foregoing,
within the meaning of Section 15 of the Act for any tax or legal advice (other

                2.2.3 CAPABILITY TO EVALUATE. Subscriber has such knowledge and

Documents (as defined in Section 2.2.4 below).

                2.2.4 DISCLOSURE DOCUMENTS. Subscriber, in making Subscriber's
investment decision to subscribe for the Securities hereunder, represents that

                2.2.5 INVESTMENT EXPERIENCE; FEND FOR SELF. Subscriber has
substantial experience in investing in securities and he, she or it has made
investments in securities other than those of the Company. Subscriber
acknowledges that Subscriber is able to fend for Subscriber's self in the
transaction contemplated by this Agreement, that Subscriber has the ability to
bear the economic risk of Subscriber's investment pursuant to this Agreement and
that Subscriber is an "Accredited Investor" by virtue of the fact that
Subscriber meets the investor qualification standards set forth in Section 2.1
above. Subscriber has not been organized for the purpose of investing in
securities of the Company, although such investment is consistent with
Subscriber's purposes.

            2.3 EXEMPT OFFERING UNDER REGULATION D.

                2.3.1 INVESTMENT; NO DISTRIBUTION. Subscriber is acquiring the
Securities to be issued and sold hereunder for his, her or its own account (or a
trust account if such Subscriber is a trustee) for investment and not as a
nominee and not with a present view to the distribution thereof. Subscriber is
aware that there are legal limits on Subscriber's ability to sell or dispose of
the Securities and, therefore, that Subscriber may be required to bear the
economic risk of the investment for an indefinite period of time and has
adequate means of providing for Subscriber's current needs and possible personal
contingencies. Subscriber's commitment to illiquid investments is reasonable in
relation to Subscriber's net worth. By making the representations in this
Section 2.3.1, the Subscriber does not agree to hold the Securities for any
minimum or other specific term and reserves the right to dispose of the
Securities at any time in accordance with or pursuant to a registration
statement or an exemption from registration under the Act, except as otherwise
limited or required by the terms hereof.

                2.3.2 [Intentionally Left Blank]

                2.3.3 RESTRICTED SECURITIES. Subscriber understands that the
Unit Shares and Warrants issued at Closing are, and the Warrant Shares will be,
characterized as "restricted securities" under the federal securities laws
inasmuch as they are being acquired from the Company in a transaction exempt
from the registration requirements of the federal securities laws and that under
such laws and applicable regulations such securities may not be transferred or
resold without registration under the Act or pursuant to an exemption therefrom.
In this connection, Subscriber represents that Subscriber is familiar with Rule
144 under the Act, as presently in effect, and understands the resale
limitations imposed thereby and by the Act.

                                       5
<PAGE>

                2.3.4 DISPOSITION. Without in any way limiting the
representations set forth above, Subscriber further agrees not to sell,
transfer, assign, pledge (except for any limited pledge in connection with a
margin account of Subscriber to the extent that such pledge does not require
registration under the Act or unless an exemption from such registration is
available and provided further that if such pledge is realized upon, any
transfer to the pledgee shall comply with the requirements set forth herein), or
otherwise dispose of all or any portion of the Securities unless and until:

                (a)     There is then in effect a registration statement under
                        the Act and any applicable state securities laws
                        covering such proposed disposition and such disposition
                        is made in accordance with such registration statement;
                        or

                (b)     (i) Subscriber shall have notified the Company of the
                        proposed disposition and shall have furnished the
                        Company with a detailed statement of the circumstances
                        surrounding the proposed disposition, and (ii) if
                        reasonably requested by the Company, Subscriber shall
                        have furnished the Company with an opinion of counsel,
                        reasonably satisfactory to the Company, that such
                        disposition will not require registration of the
                        Securities under the Act or state securities laws. It is
                        agreed that the Company will not require the Subscriber
                        to provide opinions of counsel for transactions made
                        pursuant to Rule 144 provided that Subscriber and
                        Subscriber's broker, if necessary, provide the Company
                        with the necessary representations for counsel to the
                        Company to issue an opinion with respect to such
                        transaction.

Subscriber is duly and validly organized, validly existing and in good corporate
standing as a corporation under the laws of the jurisdiction of its

            3.8 [INTENTIONALLY LEFT BLANK].

         4. REPRESENTATIONS AND WARRANTIES OF THE COMPANY . The Company hereby
makes the following representations and warranties to Subscriber (which shall be
true at the signing of this Agreement and as of Closing) and agrees with
Subscriber that:

            4.1 ORGANIZATION, GOOD STANDING, AND QUALIFICATION. The Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of the State of Delaware, USA and has all requisite corporate power and
authority to carry on its business as now conducted and as proposed to be
conducted. The Company is duly qualified to transact business and is in good
standing in each jurisdiction in which the failure to so qualify would have a
material adverse effect on the business or properties of the Company and its
subsidiaries taken as a whole. The Company is not the subject of any pending,
threatened or, to its knowledge, contemplated investigation or administrative or
legal proceeding by the Internal Revenue Service, the taxing authorities of any
state or local jurisdiction, the Securities and Exchange Commission ("SEC"), The
National Association of Securities Dealers, Inc., The Nasdaq Stock Market, Inc.
or any state securities commission, or any other governmental entity, which have
not been disclosed in the Disclosure Documents. The Company does not have any
subsidiaries, other than Peregrine Pharmaceuticals, Inc.

            4.2 CORPORATE CONDITION. The Company's condition is, in all material
respects, as described in the Disclosure Documents, except for changes in the
ordinary course of business and normal year-end adjustments that are not, in the
aggregate, materially adverse to the Company. There have been no material
adverse changes in the Company's business, prospects or financial condition
since January 6, 2000 including but not limited to incurring material
liabilities, of which any officer of the Company is aware of or should be aware
of after due inquiry. The financial statements contained in the Disclosure
Documents have been prepared in accordance with generally accepted accounting
principles, consistently applied (except as otherwise permitted by Regulation
S-X of the Exchange Act and except as otherwise disclosed in the footnotes to
the Company's financial statements), and fairly present the financial condition
of the Company as of the dates of the balance sheets included therein and the
consolidated results of its operations and cash flows for the periods then
ended. Without limiting the foregoing, there are no material liabilities,
contingent or actual, that are not disclosed in the Disclosure Documents (other
than liabilities incurred by the Company in the ordinary course of its business,
consistent with its past practice, after the period covered by the Disclosure
Documents). The Company has paid all material taxes which are due, except for
taxes which it reasonably disputes. There is no material claim, litigation, or
administrative proceeding pending, or, to the best of the Company's knowledge,
threatened against the Company or its officers and directors in their capacity
as such, except as disclosed in the Disclosure Documents. The Disclosure
Documents do not contain any untrue statement of a material fact and do not omit
to state any material fact required to be stated therein necessary to make the
statements contained therein not misleading in the light of the circumstances
under which they were made. No event or circumstance exists relating to the
Company which under applicable law, would require disclosure in a registration
statement for the primary issuance by the Company of its Common Stock but which
has not been so publicly announced or disclosed.

         8. INDEMNIFICATION.

         In consideration of each Buyer's execution and delivery of the
Subscription Agreement, Registration Rights Agreement, Irrevocable Instructions
to Transfer Agent (the "Transaction Documents") and acquiring the Securities
thereunder and in addition to all of the Company's other obligations under the
Transaction Documents, the company shall defend, protect, indemnify and hold
harmless Subscriber and all of its stockholders, officers, directors, employees
and direct or indirect investors and any of the foregoing person's agents,
members, partners or other representatives (including, without limitation, those
retained in connection with the transactions contemplated by this Agreement)
(collectively, the "Indemnitees") from and against any and all actions, causes
of action, suits, claims, losses, costs, penalties, fees, liabilities and
damages, and expenses in connection therewith (irrespective of whether any such
Indemnitee is a party to the action for which indemnification hereunder is
sought), and including reasonable attorney's fees and disbursements (the
"Indemnified Liabilities"), incurred by any Indemnitee as a result of, or
arising out of, or relating to (a) any misrepresentation or breach of any
representation or warranty made by the Company in the Transaction Documents or
any other certificate, instrument or documents contemplated hereby or thereby,
or (b) any breach of any covenant, agreement or obligation of the Company
contained in the Transaction Documents or any other certificate, instrument or
document contemplated hereby or thereby.

         To the extent that the foregoing undertaking by the Company may be
unenforceable for any reason, the Company shall make the maximum contribution to
the payment and satisfaction of each of the Indemnified Liabilities which it
would be required to make if such foregoing undertaking was enforceable which is
permissible under applicable law.

                                       16
<PAGE>

         Promptly after receipt by an Indemnified Party of notice of the
commencement of any action pursuant to which indemnification may be sought, such
Indemnified Party will, if a claim in respect thereof is to be made against the
other party (hereinafter "Indemnitor") under this Section 8, deliver to the
Indemnitor a written notice of the commencement thereof and the Indemnitor shall
have the right to participate in and to assume the defense thereof with counsel
reasonably selected by the Indemnitor, provided, however, that an Indemnified
Party shall have the right to retain its own counsel, with the reasonably
incurred fees and expenses of such counsel to be paid by the Indemnitor, if
representation of such Indemnified Party by the counsel retained by the
Indemnitor would be inappropriate due to actual or potential conflicts of
interest between such Indemnified Party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
Indemnitor within a reasonable time of the commencement of any such action, if
prejudicial to the Indemnitor's ability to defend such action, shall relieve the
Indemnitor of any liability to the Indemnified Party under this Section 8, but
the omission to so deliver written notice to the Indemnitor will not relieve it
of any liability that it may have to any Indemnified Party other than under this
Section 8 to the extent it is prejudicial.
