NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
FOR THE NINE MONTHS ENDED JANUARY 31, 2000 (UNAUDITED)
- --------------------------------------------------------------------------------

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         BASIS OF PRESENTATION. The accompanying unaudited financial statements
in this quarterly report have been prepared in accordance with the instructions
to Form 10-Q under section 13 or 15(d) of the Securities Act of 1934. The
consolidated financial statements included herein should be read in conjunction
with the consolidated financial statements of the Company, included in the
Company's Annual Report on Form 10-K for the year ended April 30, 1999, filed
with the Securities and Exchange Commission on July 28, 1999.

         The unaudited financial statements have been prepared on a going
concern basis, which contemplates the realization of assets and the satisfaction
of liabilities in the normal course of business. As shown in the financial
statements, the Company experienced losses in fiscal 1999 and during the first
nine months of fiscal 2000 and has an accumulated deficit of $104,130,000 at
January 31, 2000. These factors, among others, raise substantial doubt about the
Company's ability to continue as a going concern.

         The unaudited consolidated financial statements contain all adjustments
(consisting of only normal recurring adjustments) which, in the opinion of
management, are necessary to present fairly the consolidated financial position
of the Company at January 31, 2000 and 1999, and the consolidated results of its
operations and its consolidated cash flows for the nine month periods ended
January 31, 2000 and 1999. Results of operations for the interim periods covered
by this Report may not necessarily be indicative of results of operations for
the full fiscal year.

         The Company must raise additional funds to sustain research and
development, provide for future clinical trials and continue its operations
until it is able to generate sufficient additional revenue from the sale and/or
licensing of its products. The Company plans to obtain required financing
through one or more methods, including obtaining additional equity or debt
financing and negotiating additional licensing or collaboration agreements with
another company. There can be no assurances that the Company will be successful
in raising such funds on terms acceptable to it, or at all, or that sufficient
additional capital will be raised to complete the research, development, and
clinical testing of the Company's product candidates. The Company's continuation
as a going concern is dependent on its ability to generate sufficient cash flows
to meet its obligations on a timely basis, to obtain additional financing as may
be required and, ultimately, to attain successful operations.

         The Company believes it has sufficient cash on hand, and combined with
amounts available pursuant to the Equity Line Agreement (assuming aggregate
future draws of $5,413,000) and anticipated amounts to be received from signed
letters of intent to enter into collaboration agreements with SuperGen, Inc. and
Oxigene, Inc., to meet its obligations on a timely basis through the first
calendar quarter of 2001. The Company's ability to access funds under the Equity
Line Agreement is subject to the satisfaction of certain conditions as further
described in Note 3 to the accompanying financial statements. Each letter of
intent provides for an exclusive period for the completion of a definitive
agreement and will be subject to customary closing conditions. Although the
Company believes it will enter into definitive agreements and will receive the
related up-front payments under the terms as defined in the letters of intent,
there can be no assurance that definitive agreements will be executed.

         RECLASSIFICATION. Certain reclassifications were made to the prior
period balances to conform them to the current period presentation.

         INVENTORIES. Inventories consist of raw materials and supplies and are
stated at the lower of first-in, first-out cost or market.

         NOTE RECEIVABLE. During December 1998, the Company completed the sale
and subsequent leaseback of its two facilities and recorded an initial note
receivable from the buyer of $1,925,000. In accordance with the related lease
agreement, if the Company is in default under the lease agreement, the note
receivable shall be deemed to be immediately satisfied in full and the buyer
shall have no further obligation to the Company for such note receivable.
Although the Company had made all payments under the lease agreement and had not
defaulted under any terms of the lease agreement, the Company established a 100%
provision for the note receivable in the amount of $1,887,000, which was
recorded during the quarter ended October 31, 1999 due to the amount of cash on
hand during December 1999. The Company will continue to adjust the estimated
provision for the note receivable as payments are received. The Company has
received all payments through March 1, 2000.

         NET LOSS PER SHARE. Net loss per share is calculated by adding the net
loss for the three and nine month periods to the Preferred Stock dividends and
Preferred Stock issuance discount accretion on the Class C Preferred Stock
during the three and nine month periods divided by the weighted average number
of shares of Common Stock outstanding during the same period. Shares issuable
upon the exercise of common stock warrants and options have been excluded from
the per share calculation for the three and nine month periods ended January 31,
2000 and 1999 because their effect is antidilutive.

         RECENT ACCOUNTING PRONOUNCEMENTS. Effective May 1, 1998, the Company
adopted SFAS No. 130, Reporting Comprehensive Income, which establishes
standards for reporting and displaying comprehensive income and its components
in the consolidated financial statements. For the three and nine month periods
ended January 31, 2000 and 1999, the Company did not have any components of
comprehensive income as defined in SFAS No. 130.

         The Company adopted SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related Information" on May 1, 1998. SFAS No. 131 established
standards of reporting by publicly held businesses and disclosures of
information about operating segments in annual financial statements, and to a
lesser extent, in interim financial reports issued to stockholders. The adoption
of SFAS No. 131 had no impact on the Company's consolidated financial statements
as the Company operates in one industry segment engaged in the research,
development and commercialization of targeted cancer therapeutics.

         During June 1998, the Financial Accounting Standards Board issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities" which
will be effective for the Company beginning May 1, 2001. SFAS No. 133
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments imbedded in other contracts, and for
hedging activities. It requires an entity to recognize all derivatives as either
assets or liabilities in the statements of financial position and measure those
instruments at fair value. The Company has not determined the impact on the
consolidated financial statements, if any, upon adopting SFAS No. 133.

2.       NOTES PAYABLE

         On December 1, 1999, the Company defaulted on its monthly interest
payment of $27,500 to Biotechnology Development Ltd. on a $3,300,000 note
payable and did not file a registration statement with the Securities and
Exchange Commissions to register 1,523,809 shares of common stock and warrants
to purchase up to 4,825,000 shares of common stock by December 8, 1999 due to
the limited amount of cash on hand at that time. The note payable and shares of
common stock were issued to Biotechnology Development Ltd. upon the Company
re-acquiring certain Oncolym(R) distribution rights. The original note payable
bore simple interest at a rate of 10% per annum, payable monthly, and is due on
March 1, 2001. The note was collateralized by all tangible assets of the
Company, excluding tangible assets not located on the Company's Tustin,
California premises and those assets previously pledged and held as collateral
under separate agreements. On December 29, 1999, the Company obtained a waiver
from Biotechnology Development Ltd. for the deferral of interest payments for up
to nine months and an extension of time to register 1,523,809 shares of common
stock and warrants to purchase up to 4,825,000 shares of common stock until the
Company's next registration statement filing. In exchange for this waiver, the
Company agreed to (i) increase the rate of interest from 10% per annum to 12%
per annum on the note payable of $3,300,000 effective December 1, 1999, (ii)
replace the current collateral with the rights to the TNT technology (iii)
extend the expiration date of 5,325,000 warrants to December 1, 2005 and (iv)
only in the case of a merger, acquisition, or reverse stock split, re-price up
to 5,325,000 warrants to an exercise price of $0.34 per share. Biotechnology
Development Ltd. is a limited partnership controlled by Mr. Edward Legere, a
member of the Board of Directors since December 29, 1999.

3.       STOCKHOLDERS' EQUITY

         During June 1998, the Company secured access to $20,000,000 under a
Common Stock Equity Line ("Equity Line") with two institutional investors,
expiring in June 2001. Under the terms of the Equity Line, the Company may, in
its sole discretion, and subject to certain restrictions, periodically sell
("Put") shares of the Company's Common Stock for up to $20,000,000. Under the
Equity Line, $2,250,000 of Puts can be made every quarter, which amount may be
increased up to $5,000,000 by mutual agreement between the Company and the
institutional investors. If the Company's closing bid price falls below $1.00 on
any day during the ten trading days prior to the Put, the Company's ability to

- --------------------------------------------------------------------------------

access funds under the Equity Line in the Put is limited to 15% of what would
otherwise be available and if the closing bid price of the Company's Common
Stock falls below $0.50 or if the Company is delisted from The Nasdaq SmallCap
Market, the Company would have no access to funds under the Equity Line. As of
March 1, 2000, the Company had $5,413,000 available for future Puts under the
Equity Line.

         Future Puts under the Equity Line are priced at a discount equal to the
greater of $0.20 or 17.5% off the lowest closing per share bid price during the
ten trading days immediately preceding the date on which such shares are sold to
the institutional investors.

         At the time of each Put, the institutional investors are issued
warrants, exercisable only on a cashless basis and expiring on December 31,
2004, to purchase up to 10% of the amount of Common Stock issued to the investor
at the same price as the purchase of the shares sold in the Put.

         Placement agent fees under each draw of the Equity Line are issued to
Dunwoody Brokerage Services, Inc., which are equal to 10% of the common shares
and warrants issued to the institutional investors plus an overall cash
commission equal to 8% of the gross draw amount. Mr. Eric Swartz, a member of
the Board of Directors, maintains a contractual right to 50% of the shares and
warrants issued under the Equity Line in the name of Dunwoody Brokerage
Services, Inc.

         To maintain the Company operations during a period of time when the
Company's stock was trading around $0.50 per share, the Company issued 2,683,910
shares of common stock in exchange for gross proceeds of $675,000 under two
separate draws under the Equity Line, which occurred during the quarter ended
January 31, 2000. On one Equity Line draw, the Company obtained a limited,
one-time waiver from the institutional investors, whereby the investors reduced
the minimum bid price requirement under the Equity Line Agreement from $0.50 per
share during the ten trading days immediately prior to the closing date for such
funding to $0.40 per share during such ten-day period.

         On November 19, 1999, in consideration of a commitment by Swartz
Private Equity, LLC to fund a $35,000,000 equity line financing over a three
year term, the Company issued Swartz Private Equity, LLC a five-year warrant to
purchase up to 750,000 shares of the Company's Common Stock at an initial
exercise price of $0.46875 per share subject to reset provisions as defined in
the agreement. This agreement was entered into and approved by the previous
Board of Directors. Mr. Eric Swartz, a member of the Board of Directors,
maintains a 50% ownership in Swartz Private Equity, LLC.

         On December 29, 1999, Swartz Investments, LLC and Biotechnology
Development Ltd. agreed to provide interim funding to the Company for up to
$500,000 to continue the operations of the Company and to avoid the Company from
filing for protection from its creditors. During this period of time, the
closing stock price was $0.41 per share, the Company had minimal amount of cash

on hand, significant payables to vendors and patent attorneys, and the Company
was near a time of being delisted from The NASDAQ Stock Market. On January 6,
2000, the Company entered into the final agreement, a Regulation D Subscription
Agreement, whereby the Company received $500,000 in exchange for an aggregate of
2,000,000 shares of common stock and issued warrants to purchase up to 2,000,000
shares of common stock at $0.25 per share. Mr. Eric Swartz, a member of the
Board of Directors, maintains a 50% ownership in Swartz Investments, LLC.
Biotechnology Development Ltd. is controlled by Mr. Edward Legere. Mr. Legere
was appointed to the Board of Directors on December 29, 1999.

         During the quarter ended January 31, 2000, the Company issued 2,001,767
shares of common stock upon the exercise of outstanding options and warrants in
exchange for gross proceeds of $1,825,000. There are no further options or
warrants outstanding to previous officers, board members or other employees of
the Company.

         During the quarter ended January 31, 2000, the Company issued 203,165
shares of common stock to various service vendors of the Company as payment of
liabilities aggregating $311,000. The issuance of shares of common stock in
exchange for services were recorded based on the more readily determinable value
of the services received or the fair value of the common stock issued.

4.       STOCK OPTIONS

         During December 1999, the Company had a minimal amount of cash on hand
and certain employees of the Company were deferring a percentage of their
salary. In addition, the Company had significant payables to vendors and patent
attorneys and the Company was near a time of being delisted from The NASDAQ
Stock Market. Also, the Company was aware of numerous employees who had job
opportunities with companies who had stronger financial resources. In order for
the Company to continue, the Board of Directors felt it was imperative for the
Company to maintain certain key employees who were familiar with the Company's
technologies, clinical trials and business activities. Therefore, on December
22, 1999, the Board of Directors granted 4,170,000 options to various employees,
consultants and two Board members at exercise prices ranging from $0.34 to
$30.00 per share. The majority of the options granted will vest upon the
achievement of Company milestones as defined by the Board of Directors. Key
milestones as defined by the Board will be based on significant licensing
transactions, financing activities, meeting key clinical trial milestones, and
research and development activities. The options were granted to purchase shares
of the Company's common stock at prices not less than the fair market value of
the stock at the date of grant and generally expire ten years after the date of
grant.

5.       LICENSE, RESEARCH AND DEVELOPMENT AGREEMENTS

         On November 29, 1999, the Company entered into a 90-day option
agreement with a multinational pharmaceutical company to potentially license a
specific use of the TNT technology for a nonrefundable $50,000 option fee. The
Company is in continued negotiations with the multinational pharmaceutical
company. There can be no assurances that the Company will be successful in
entering into such licensing transaction on terms that are mutually acceptable.

         On January 12, 2000, the Company signed a letter of intent to license a
segment of its Vascular Targeting Agent (VTA) technology, specifically related
to Vascular Endothelial Growth Factor (VEGF), with SuperGen, Inc. in exchange
for an upfront payment and milestone payments aggregating approximately
$8,000,000 plus a royalty on net sales. The transaction is subject to further
medical, technical, business, financial and legal due diligence and will be
subject to customary closing conditions. There can be no assurance that the
Company will enter into a definitive agreement.

         On January 27, 2000, the Company executed its option agreement with the
University of Texas Southwestern Medical Center, Dallas (University) to obtain
an exclusive world-wide license for a novel anti-angiogenesis antibody named 2C3
and its derivatives. The antibody is an anti-VEGF (Vascular Endothelial Growth
Factor) antibody with the ability to block the binding of a growth factor to
receptors found on tumor vasculature, the effect is to inhibit tumor vessel
growth. The license agreement is currently being drafted by the University.

         During February 2000, the Company entered into an exclusive worldwide
licensing transaction with the University of Southern California for its
Permeability Enhancing Protein (PEP) in exchange for an up-front payment plus
milestone payments and a royalty on net sales. The PEP technology is a piece of
the Company's Vasopermeability Enhancing (VEA) technology, which is designed to
increase the uptake of chemotherapeutic agents into tumors. PEP is designed to
be used in conjunction the VEA technology platform.

6.       CONTINGENCY

         On March 18, 1999, the Company was served with notice of a lawsuit
filed in Orange County Superior Court for the State of California (Superior
Court) by a former employee alleging a single cause of action for wrongful
termination. The Company believes this lawsuit is barred by a severance
agreement and release signed by the former employee following his termination
and the Company is defending the action. On September 13, 1999, the Superior
Court granted Techniclone a Motion for Summary Judgement and the Company was not
obligated for any damages. On November 12, 1999, a Notice of Entry of Judgement
was filed by the Superior Court. Subsequently, the former employee appealed the
Summary Judgement. The Company will continue to defend the action.

7.       SUBSEQUENT EVENTS

         During February 2000, the Company received gross proceeds of $4,325,000
in exchange for 1,596,255 shares of common stock under the Equity Line. Dunwoody
Brokerage Services, Inc. was issued 145,114 shares of common stock and warrants
to purchase up to 14,510 shares of common stock as placement agent fees under
the Equity Line.

         In early March 2000, the Company signed a Letter of Intent to jointly
develop and commercialize the Company's Vascular Targeting Agent (VTA)
technology with Oxigene, Inc. Oxigene, Inc. will make available to the project
its next generation of tubulin-binding compounds for use in combination with the
VTA technology. The joint venture arrangement will include an upfront licensing
fee and milestone payments to the Company as well as substantial funding of
development expenses related to commercializing a VTA product by Oxigene, Inc.
The Company and Oxigene, Inc. will also share royalties and certain fees
generated by the joint venture. The letter of intent provides for an exclusive
period for the completion of a definitive agreement. The transaction is subject
to further medical, technical, business, financial and legal due diligence and
will be subject to customary closing conditions. There can be no assurance that
the Company will enter into a definitive agreement.

         Subsequent to January 31, 2000, the Company has made significant
payments and reduced the amounts owed for accounts payable and other current
liabilities. As of March 9, 2000, the Company reduced its accounts payable
balance by $1,419,000 from $1,587,000 as of January 31, 2000 to approximately
$168,000 as of March 9, 2000. In addition, accrued clinical trial site fees were
reduced by $268,000 from $919,000 as of January 31, 2000 to approximately
$651,000 as of March 9, 2000. The remaining clinical trial site fees will be
paid by the Company once the clinical trial sites have submitted all necessary
paperwork and supporting documentation. After the above payments were made, the
Company had approximately $4,724,000 in cash and cash equivalents as of March 9,
2000.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
- -------  -----------------------------------------------------------------------
         OF OPERATIONS
         -------------

         The following discussion contains, in addition to historical
information, forward-looking statements that involve risks and uncertainties.
Actual results may differ significantly from the results discussed in the
forward-looking statements. Factors that could cause or contribute to such
differences include, but are not limited to, those discussed below and included
in the Company's Annual Report on Form 10-K for the year ended April 30, 1999,
filed with the Securities and Exchange Commission on July 28, 1999 and Quarterly
Reports on Form 10-Q for the quarters ended July 31, 1999 and October 31, 1999,
filed with the Securities and Exchange Commission on September 10, 1999 and
December 15, 1999, respectively.

         COMPANY OVERVIEW. Techniclone Corporation is a biopharmaceutical
company engaged in the research, development and commercialization of targeted
cancer therapeutics. We are developing product candidates based primarily on
collateral (indirect) tumor targeting for the treatment of solid tumors. In
addition, we are in collaboration with Schering A.G. to develop a direct
tumor-targeting agent (Oncolym(R)) for the treatment of Non-Hodgkins Lymphoma
(NHL).

         Collateral targeting is a strategy that has been developed to take
advantage of characteristics common to all solid tumors. These common tumor
characteristics include all solid tumors in excess of 2mm in size which must
develop a blood supply in order to continue growing. While all solid tumors in
excess of 2mm in size do develop a blood supply, they do not develop an adequate
blood supply. The lack of an adequate blood supply results in starvation and
eventually death of tumor cells farthest from the tumor blood vessels. These
dying and dead tumor cells are known as the necrotic core of the tumor. The
inadequate formation of blood vessels to carry blood into and out of the tumor
results in the build-up of pressure inside the tumor. This pressure build-up
makes it difficult to deliver adequate amounts of cancer chemotherapeutics into
the tumor and to the living tumor cells that are the target.

         The most clinically advanced of the Collateral Targeting Agents is
known as Tumor Necrosis Therapy (TNT), which utilizes monoclonal antibodies
(targeting molecules that bind to specific structures) that recognize markers
found in the necrotic core of solid tumors. TNT antibodies are potentially
capable of carrying a variety of agents including radiation, chemotherapeutic
agents and cytokines to the interior of solid tumors. A Phase II clinical trial
for a Tumor Necrosis Therapy agent (called Cotara(TM)) for the treatment of
malignant glioma (brain cancer) is currently being conducted at The Medical
University of South Carolina, Temple University, University of Utah-Salt Lake
City and Carolina Neurosurgery & Spine Association. In addition, our Tumor
Necrosis Therapy agent is being used in a Phase I equivalent clinical trial for
the treatment of pancreatic, prostrate and liver cancers at a clinical trial
site in Mexico City.

         The second type of Collateral Targeting Agents that we are developing
are Vascular Targeting Agents (VTAs). VTAs utilize monoclonal antibodies that
recognize markers found on tumor blood vessels. The monoclonal antibody carries
an effector molecule that creates a blockage within the blood vessels that
supply oxygen and nutrients to the tumor cells. Cutting off the blood supply to
the tumor results in tumor cell death, potentially destroying the tumor. VTAs
are currently in pre-clinical development in collaboration with researchers at
the University of Texas Southwestern Medical Center at Dallas.

                                       16
<PAGE>

         The third type of Collateral Targeting Agents that Techniclone is
currently developing are known as Vasopermeation Enhancement Agents (VEA). VEAs
currently use the same targeting agent as TNT to deliver an agent that makes the
blood vessels inside the tumor more leaky (permeable). The increased
permeability of the tumor blood vessels makes it possible to deliver an
increased concentration of killing agents into the tumor where it can
potentially kill the living tumor cells. VTAs are currently in pre-clinical
development in collaboration with researchers at the University of Southern
California Medical Center.

         Techniclone has taken steps to protect its position in the field of
Collateral Targeting Agents. Techniclone currently has exclusive rights to over
30 issued US and Foreign patents protecting various aspects of Collateral
Targeting. In addition, Techniclone still has outstanding U.S. and foreign
patent applications that will potentially provide further protection for its
Collateral Targeting Agents. Techniclone is currently in pre-clinical or
clinical development of three Collateral Targeting Agents for the treatment of
solid tumors.

         On March 8, 1999, Techniclone entered into a license agreement with
Schering A.G., a major multinational pharmaceutical company, with respect to the
development, manufacture and marketing of its direct tumor targeting agent
candidate, Oncolym(R). Under the agreement, Schering A.G. controls the clinical
development program and funds 80% of the clinical trial costs. The current Phase
II/III clinical trial has been stopped by Schering A.G. Schering A.G. has
advised the Company that they currently anticipate starting a Phase I/II dosing
trial for 18 patients under a new dosing regiment during the second calendar
quarter of 2000.

         RECENT DEVELOPMENTS. The management team and the Board of Directors of
Techniclone Corporation has changed dramatically since November 3, 1999. During
November 1999, four of the Company's five Board members, Larry O. Bymaster,
Rockell Hankin, William C. Shepherd and Thomas R. Testman, resigned. Mr. Eric
Swartz and Mr. Carlton Johnson were appointed as new members of the Board. On
December 29, 1999, the Board appointed Mr. Edward Legere to serve on the Board
of Directors. Currently, the Board is comprised of the following four members:
Mr. Carlton Johnson, Mr. Edward Legere, Mr. Eric Swartz, and Mr. Clive Tayor,
M.D. Also in November 1999, Mr. Bymaster resigned as President Chief Executive
Officer and Mr. Steven C. Burke resigned as Chief Financial Officer and
Corporate Secretary. The Board appointed Dr. John N. Bonfiglio, the Company's
Vice President of Technology and Business Development, as Interim President. The
Company is currently operating with approximately 15 employees compared to
approximately 50 employees who were employed by the Company in October 1999.

         With the recent changes in management and the Board of Directors, the
Company has adopted a new strategic business plan. During the quarter ended
January 31, 2000, the Company's new management and Board of Directors conducted
a thorough evaluation of the Company's business plans, operations and funding
requirements. In the past five years, significant financial resources of the
Company have been spent on GMP (Good Manufacturing Practices) manufacturing
infrastructure, corporate facility improvements, staffing and other support
activities. Based on our evaluation of the Company, management and the Board of
Directors have implemented the following plan for the Company:

                                       17
<PAGE>

         CORPORATE STRUCTURE. The objective of the new management and Board of
Directors is to focus the Company's resources almost exclusively on clinical
trials, licensing and early product development. The Company's new plan started
with the elimination of the in-house manufacturing activities, which reduced the
level of support staff and fixed overhead costs that it had incurred in the
past. The Company will also outsource various clinical trial activities, which
will allow the Company to better predict and manage its costs on a project
specific basis. The Company will continue to outsource its research efforts
through its agreements with the University of Southern California and the
University of Texas Southwestern Medical Center at Dallas. The Company has
maintained a core group of employees that will plan, coordinate and monitor all
product development and clinical trial activities being conducted by outside
parties. In addition, the core group of employees will also maintain the product
development activities and technology transfer activities associated with
outsourcing manufacturing.

         MANUFACTURING. Operating a GMP manufacturing facility requires highly
specialized personnel and equipment which must be maintained on a continual
basis. Although the Company believes it has derived substantial benefits from
its manufacturing operations, management and the Board of Directors believe that
maintaining a GMP manufacturing facility is not an efficient use of Company
resources at this time. The Company plans on utilizing contract manufacturers
with excess capacity to provide cost effective GMP manufacturing of its Oncolym,
Cotara(TM) and future products under development. The Company has manufactured a
sufficient antibody supply to meet its current clinical trial needs for its
Oncolym(R) and Cotara(TM) technologies. The Company has maintained key
development personnel who will be responsible for developing analytical methods
and processes that will facilitate the transfer of technology to contract
manufactures. The Company has prepared for the smooth transfer of manufacturing
technology to contract manufacturers and it does not anticipate any delays in
its ongoing projects.

         As part of this new manufacturing strategy, the Company has arranged to
have the owner list the manufacturing facility and related equipment for sale.
As the building and related manufacturing improvements are owned by TNCA, LLC,
only the proceeds from the sale of manufacturing equipment will be paid directly
to the Company. In addition, if the manufacturing facility is sold by TNCA, LLC,
the Company would receive approximately $936,000 as payment on a note receivable
from TNCA, LLC. The note receivable was received upon to the sale and subsequent
leaseback of the Company's facilities in December 1998. To date, the Company has
realized a significant reduction of monthly fixed overhead expenses from the
discontinuation of the manufacturing operations. The Company anticipates
additional reductions in fixed overhead costs related to the cessation of
manufacturing activities and the disposal or subleasing of the manufacturing
facility.

         LICENSING. The Company has considered licensing an important part of
its strategic plan. On March 8,1999, the Company entered into a licensing
agreement (the License Agreement) for the worldwide exclusive license for
Oncolym(R) with Schering A.G. Germany (Schering). As part of the Licensing
Agreement, Schering requested a term sheet for the exclusive license to the
Vascular Targeting Agent (VTA) technology, which was attached as Exhibit D (the
"Exhibit") to the License Agreement. The term sheet was designed to give
Schering a 30-day exclusive right of first refusal. Following the initial 30-day
period, an additional 30-day period was agreed to during both Schering and
Techniclone continued to be bound by the terms in the Exhibit. Schering also
maintained the right for one year to match any offer put forth by another
company as long as the terms offered were less favorable or equal to the terms
in the letter of intent. The Company felt that the Schering terms were favorable
enough that when Schering asked for an extension on the term sheet because of
internal corporate delays in completing their due diligence, extensions were
granted. This extended the exclusive period by several months. In August 1999,
Schering informed the Company that they wanted to revise the terms of the term
sheet, making the terms less favorable to the Company. While the Board of
Directors were reviewing the new terms, Schering informed the Company that it
was retracting its latest offer. No official reason was given for the change.

                                       18
<PAGE>

         Since the term sheet for the VTA technology never reached a final
agreement, the Company decided to review its strategy for the licensing of the
VTA technology. The Company felt that a single corporate partner would most
likely develop only one product candidate. It was apparent from the breadth of
the technology and the continued issuance of patents in this field that simply
having one corporate partner to develop this technology was not going to fully
exploit the high potential of the technology. Therefore, the Company decided to
seek out exclusive licenses for pieces of the technology while simultaneously
looking for a corporate partnership that would allow the Company to maintain
some control over the development of the most likely commercial entities from
this technology. The pending agreements with Supergen, Inc. and Scotia Holdings
are examples of this strategy. Both of these companies have entered into letters
of intent to license very specific aspects of the VTA technology that the
Company, in collaboration with Dr. Phil Thorpe, the inventor of the technology,
has decided not to pursue. This decision will put these aspects of the
technology into the hands of companies dedicated to these very specialized
areas, thus increasing the chance of a commercial product from these areas.
Simultaneously, the Company decided to enter into a joint venture with Oxigene,
Inc., which was announced on Wednesday, May 17, 2000. The Company believes that
this joint venture offers several advantages for the Company in terms of
exploiting the VTA technology, including, but not limited to the following:

     1.   Oxigene, with its compound Combretastatin, is a recognized leader in
          the field of vascular targeting for the treatment of cancer. Oxigene's
          development experience to the VTA area will be extremely valuable to
          the joint venture.

     2.   Oxigene will contribute its next generation tubulin-binding technology
          to the joint venture for use in combination with the VTA technology,
          which is an excellent fit with the VTA technology.

     3.   Oxigene's committed funding of the joint venture will insure that the
          VTA technology is fully developed and also allows the Company to focus
          its funds on our other platform technologies.

     4.   The Company, as part of this joint venture, will be highly involved in
          all decisions related to the continued development of the VTA
          technology. Unlike a straight licensing arrangement, the Company will
          be able to continue to develop the VTA area as a full partner.

     5.   The Oxigene deal also allows the Company to continue to enter into
          additional licensing transactions similar to the pending Supergen,
          Inc. and Scotia Holdings transactions, which will insure the full
          exploitation of the VTA technology.

     6.   The Oxigene deal will split profits equally between the Company and
          Oxigene, Inc. While most licensing agreements would have resulted in a
          royalty from a licensee, this strategy will potentially give the
          Company a larger share of profits and it also allows the joint venture
          flexibility in deciding whether to license a product to a larger
          company or to take it to the market without help from outside
          companies.

         Based on the above, the Company believes that the decision to not
license the technology to one single partner and to adopt a strategy of
consummating multiple licensing transactions or strategic partnerships for
specific uses of the technology, such as the joint venture with Oxigene, Inc.,
is in the best interest of the technology, the Company and ultimately the
Company's shareholders. The Company believes this strategy may increase the
chances that one or several anti-cancer products will be commercialized
utilizing its technologies. The Company believes there are numerous
opportunities for non-exclusive licensing of its TNT and VTA platform
technologies. In addition, by granting non-exclusive licensing to other
companies, the Company maintains the ability to develop its own products for
commercialization, such as Cotara(TM). This approach should increase the revenue
potential of these two promising platform technologies as well as permit the
Company to commercialize its own proprietary anti-cancer product.

                                       19
<PAGE>

         CLINICAL TRIALS. Moving forward, the most critical aspect of the
Company's business plan will be centered around clinical trials with the
Company's various technologies. The Company plans to expand its clinical studies
for its Cotara(TM) monoclonal antibody. Cotara(TM) is currently in a U.S.
multi-center clinical trial for the treatment of brain cancer. Because of
Cotara's(TM) ability to selectively target multiple cancer types, the Company
intends to expand its clinical studies to additional cancer types. The
additional clinical studies will be initiated as the Company obtains the
financial resources to support such activities.

         In addition, Schering A.G. has advised the Company that they currently
anticipate starting a dosing trial for 18 patients under a new dosing regiment
during the second calendar quarter of 2000 to the treatment of Non-Hodgkins
Lymphoma (NHL) using the Company's Ocolym(R) technology.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JANUARY 31, 2000 AND 1999

         The following is a historical summary of the Company's operational burn
rate for the quarter ended January 31, 2000 compared to the same period in the
prior year. As shown in the schedule below, the Company's operational burn rate
has decreased $1,090,000 or approximately 42% in the current quarter ended
January 31, 2000 compared to the same period in the prior year. As further shown
in the below schedule, the average monthly operational burn rate has decreased
$363,000 per month for each month in the quarter ended January 31, 2000 compared
to the same average monthly periods in the prior year. In addition, the
Company's recurring monthly fixed expenses for salaries, facilities and related
overhead charges and general and administrative expenses (monthly fixed burn
rate) were approximately $316,000 per month for the quarter ended January 31,
2000 compared to approximately $435,000 per month for the same period in the
prior year or a savings of $119,000 per month. The Company has listed its excess
space for sublease and upon the Company subleasing such space, the Company
expects the monthly fixed burn rate to continue to decrease in comparison to the
same periods in the prior year. However, our total operational burn rate will
vary substantially from quarter to quarter based on patient enrollment rates of
our clinical trial programs, and the funding of non-recurring items, which may
include but are not limited to, items associated with product development,
contract manufacturing and contract radiolabeling and the related commercial
scale-up efforts of contract manufacturing and contract radiolabeling.

         Net Loss. The Company's net loss, before preferred stock discount
accretion and dividends, for the current quarter ended January 31, 2000
decreased $1,636,000 in comparison to the same period in the prior year. This
current quarter decrease in net loss is due to a $1,611,000 decrease in total
costs and expenses combined with an increase in interest and other income of
$25,000.

                                       20
<PAGE>

         Total Costs and Expenses. The decrease in total costs and expenses of
$1,611,000 during the current quarter compared to the same period in the prior
quarter resulted primarily from the one-time prior-year quarter non-cash charge
of $1,171,000 recorded in December 1998 in connection with the sale and
subsequent leaseback of the Company's two facilities. This decrease was combined
with a current quarter decrease in research and development expenses of $437,000
and a decrease in general and administrative expenses of $73,000, which were
offset by an increase in interest expense of $70,000.

         Research and Development Expenses. The decrease in research and
development expenses of $437,000 during the current quarter ended January 31,
2000 primarily relates to a decrease in personnel, manufacturing, consulting,
radiolabeling and travel expenses offset by an increase in clinical trial,
sponsored research and building lease expenses. The decrease in the above
expense resulted primarily from the Company's direct efforts to reduce its cash
expenses related to internal research and development and manufacturing while
continuing its clinical trial programs and university research and development.
On October 18, 1999, the Company decreased the number of employees from
approximately 50 employees to 25 employees in an effort to reduce the Company's
burn rate or cash consumption rate and to preserve its then cash on hand. The
majority of the personnel reductions came from the Manufacturing Department and
ancillary departments to support the clinical manufacturing of its antibodies
under development. The Company believes it can contract out certain
manufacturing and research services previously performed in-house at a reduced
cost compared to the internal personnel and overhead costs to run such programs.

         General and Administrative Expenses. The decrease in general and
administrative expenses of $73,000 during the quarter ended January 31, 2000
compared to the quarter ended January 31, 1999 resulted primarily from a
decrease in consulting fees, severance expenses, personnel costs and other
reductions in general expenses of $468,000. On November 3, 1999, the Company's
former Chief Executive Officer and Chief Financial Officer resigned with a
quarterly aggregate base salary of $109,000 and such positions were replaced
with internal positions, thus decreasing the quarterly general and
administrative personnel costs. The current quarter decrease in the above
expenses was offset by an increase in stock-based compensation expense (a
non-cash expense) of $395,000. The Company expects general and administrative
expenses (excluding stock-based compensation) to decrease in future quarters
compared to the same period in prior quarters as all severance agreements have
been completed and as the Company has decreased its overall headcount and
aggregate gross salaries in the Administration Department.

         Interest Expense. The increase in interest expense of approximately
$70,000 for the quarter ended January 31, 2000 compared to the same period in
the prior year is primarily due to an increase in interest charges on a
$3,300,000 note payable to Biotechnology Development Ltd. related to the buyback
of the Oncolym(R) rights on March 8, 1999 as such amounts were not incurred in
the same quarter of the previous year.

         Interest and Other Income. The increase in interest and other income of
$25,000 during the three month period ended January 31, 2000 compared to the
same period in the prior year is primarily due a $50,000 nonrefundable option
fee received in November 1999 for a 90-day option agreement with a multinational
pharmaceutical company to potentially license a specific use of the TNT
technology primarily offset by a decrease in rental income. The Company's excess
space is currently being listed for sale by the owner of the buildings and is
also being listed for sublease by the Company. If the Company is able to
sublease the excess space, rental income will increase in future months which
will reduce the Company's overall burn rate. The Company does not expect to
generate product sales for at least the next year.

NINE MONTHS ENDED JANUARY 31, 2000 AND 1999

         Net Loss. The Company's net loss for the nine months ended January 31,
2000 increased $205,000 compared to the nine months ended January 31, 1999. The
increased loss for the current nine-month period was due to a $193,000 increase
in total costs and expenses combined with a $12,000 decrease in interest and
other income.

         Total Costs and Expenses. The Company's total costs and expenses
increased $193,000 for the nine months ended January 31, 2000 compared to the
same period in the prior year. This nine month increase in expenses resulted
primarily from recording a non-cash expense for the estimated provision of an
uncollectable note receivable of $1,887,000 in October 1999 combined with an
increase in research and development expenses of $148,000. These amounts were
offset by a current nine month period decrease in general and administrative
expenses of $575,000 and a decrease in interest expense of $90,000. In addition,
during the prior quarter ended January 31, 1999, the Company recorded a loss on
the sale and subsequent lease-back of the Company's two facilities and other
property of $1,177,000, which was not incurred during the current nine month
period.

         Research and Development Expenses. The increase in research and
development expenses of $148,000 during the nine months ended January 31, 2000
primarily relates to increased research fees from MDS Nordion associated with
the development of a commercial radiolabeling facility combined with an increase
in sponsored research for the development of the Vascular Targeting Agent
technology. Also, the Company incurred increased costs to reengineer the
Company's TNT clone, which will significantly increase the manufacturing
production yields and will significantly reduce future antibody costs. In
addition, during the nine months ended January 31, 2000, the Company incurred
increased building lease expense related to the sale and subsequent leaseback of
the Company's facilities in December 1998 partially offset by a corresponding
decrease in depreciation expense on the related building. The above increase in
costs were partially off-set by a decrease in research and development costs for
the quarter ended January 31, 2000 as described above.

         General and Administrative Expenses. General and administrative
expenses decreased approximately $575,000 for the nine months ended January 31,
2000 compared to the same period in the prior year primarily due to decreases in
shareholder meeting costs, consulting fees, legal fees, travel expenses,
severance and personnel expenses, and others expenses aggregating $1,096,000,
which was offset by an increase in stock-based compensation (a non-cash
expenses) of $521,000.

         Interest Expense. Interest expense decreased $90,000 during the
nine-month period ended January 31, 2000 compared to the same period in the
prior year primarily due to interest charges on construction costs incurred in
the prior year nine month period related to manufacturing facility enhancements
combined with mortgage interest on the Company's facilities, both of which were
not incurred in the current nine-month period. Such decrease was partially
offset by an increase in interest charges on a $3,300,000 note payable to
Biotechnology Development Ltd. related to the buyback of the Oncolym(R) rights
on March 8, 1999.

         Interest and Other Income. The decrease in interest and other income of
$12,000 during the nine months ended January 31, 2000 is primarily due to a
decrease in rental income offset by a $50,000 nonrefundable option fee received
in November 1999 for a 90-day option agreement with a multinational
pharmaceutical company to potentially license a specific use of the TNT
technology.

         LIQUIDITY AND CAPITAL RESOURCES. The Company experienced losses in
fiscal 1999 and during the first nine months of fiscal 2000 and has an
accumulated deficit of $104,130,000 at January 31, 2000. These factors, among
others, raise substantial doubt about the Company's ability to continue as a
going concern.

         The Company must raise additional funds to sustain research and
development, provide for future clinical trials and continue its operations
until it is able to generate sufficient additional revenue from the sale and/or
licensing of its products. The Company plans to obtain required financing
through one or more methods including, obtaining additional equity or debt
financing and negotiating additional licensing or collaboration agreements with
another company. There can be no assurances that the Company will be successful
in raising such funds on terms acceptable to it, or at all, or that sufficient
additional capital will be raised to complete the research, development, and
clinical testing of the Company's product candidates. The Company's continuation
as a going concern is dependent on its ability to generate sufficient cash flows
to meet its obligations on a timely basis, to obtain additional financing as may
be required and, ultimately, to attain successful operations. Management knows
that additional capital must be raised in the near term to support the Company's
continued operations and other short-term cash needs.

         The Company believes it has sufficient cash on hand and combined with
amounts available pursuant to the Equity Line Agreement (assuming aggregate
future draws of $5,413,000) and anticipated amounts to be received from signed
letters of intent to enter into collaboration agreements with SuperGen, Inc. and
Oxigene, Inc. to meet its obligations on a timely basis through the first
calendar quarter of 2001. The Company's ability to access funds under the Equity
Line Agreement is subject to the satisfaction of certain conditions as further
described in Note 3 to the accompanying financial statements. The letters of
intent provides for an exclusive period for the completion of a definitive
agreement and will be subject to customary closing conditions. Although the
Company believes it will enter into definitive agreements and will receive the
related up-front payments under the terms as defined in the letters of intent,
there can be no assurance that definitive agreements will be reached.

         We have significant commitments to expend additional funds for
preclinical development, clinical trials, radiolabeling contracts, license
contracts and consulting. If we obtain the necessary funding, we expect
operating expenditures related to clinical trials to increase in the future as
our clinical trial activity increases and scale-up for clinical trial production
continues. We have experienced negative cash flows from operations since our
inception, and we expect the negative cash flows from operations to continue for
the foreseeable future. We expect that the monthly negative cash flow will
continue for at least the next year as a result of activities in connection with
the Phase II clinical trials of Cotara(TM) and the equivalent Phase I clinical
trials of Cotara(TM) in Mexico and the development costs associated with
Vasopermeation Enhancement Agents ("VEAs") and Vascular Targeting Agents
("VTAs").

         There can be no assurance that we will be successful in raising such
funds on terms acceptable to us, or at all, or that sufficient capital will be
raised to complete the research and development of our product candidates.

                                       23
<PAGE>

         COMMITMENTS. At January 31, 2000, we had no capital commitments,
although we have significant obligations, most of which are contingent, for
payments to licensors for technologies and in connection with the acquisition of
the Oncolym(R) rights previously owned by Alpha Therapeutic Corporation
("Alpha").

         OTHER RISK FACTORS OF OUR COMPANY. The biotechnology industry includes
many risks and challenges. Our challenges may include, but are not limited to:
uncertainties associated with completing pre-clinical and clinical trials for
our technologies; the significant costs to develop our products as all of our
products are currently in development, preclinical studies or clinical trials
and no revenue has been generated from commercial product sales; obtaining
additional financing to support our operations and the development of our
products; obtaining regulatory approval for our technologies; complying with
other governmental regulations applicable to our business; obtaining the raw
materials necessary in the development of such compounds; consummating
collaborative arrangements with corporate partners for product development;
achieving milestones under collaborative arrangements with corporate partners;
developing the capacity to manufacture, market and sell our products, either
directly or indirectly with collaborative partners; developing market demand for
and acceptance of such products; competing effectively with other pharmaceutical
and biotechnological products; attracting and retaining key personnel;
protecting proprietary rights; accurately forecasting operating and capital
expenditures, other capital commitments, or clinical trial costs and general
economic conditions. For additional information regarding the industry and
Company challenges are discussed in the Company's Annual Report on Form 10-K for
the year ended April 30, 1999, filed with the Securities and Exchange Commission
on July 28, 1999 and Quarterly Reports on Form 10-Q for the quarters ended July
31, 1999 and October 31, 1999, filed with the Securities and Exchange Commission
on September 10, 1999 and December 15, 1999, respectively.

         Other risks to consider may include, but are not limited to, the
following:

IF OUR RELATIONSHIP WITH SCHERING A.G. TERMINATES, IT COULD ADVERSELY AFFECT OUR
BUSINESS.

         In March 1999, we entered into a license agreement with Schering A.G.,
for the worldwide development, marketing and distribution of our direct tumor
targeting agent product candidate, Oncolym(R). Under the agreement, Schering
A.G. has assumed control of the clinical development program, regulatory
approvals in the United States and all foreign countries and sales and marketing
of this product candidate. Schering A.G. may terminate the agreement under a
number of circumstances as defined in the agreement, including thirty days'
written notice given at any time prior to receiving regulatory approval. We are
relying on Schering A.G. to apply its expertise and know-how to the development,
launch and sale of this product candidate. If Schering A.G. decides to
discontinue the development of this product candidate and terminates our license
agreement, we may have to discontinue development, commercialization and
clinical testing of this product candidate, which could negatively affect our
operations and financial performance. We cannot guarantee that Schering A.G.
will devote the resources necessary to successfully develop and/or market any
product candidate.

THE LIQUIDITY OF OUR COMMON STOCK WILL BE ADVERSELY AFFECTED IF OUR COMMON STOCK
IS DELISTED FROM THE NASDAQ SMALLCAP MARKET.

         The Common Stock of the Company is presently traded on The Nasdaq
SmallCap Market. To maintain inclusion on The Nasdaq SmallCap Market, we must
continue to have either net tangible assets of at least $2,000,000, market
capitalization of at least $35,000,000, or net income (in either our latest
fiscal year or in two of our last three fiscal years) of at least $500,000. In
addition, we must meet other requirements, including, but not limited to, having
a public float of at least 500,000 shares and $1,000,000, a minimum closing bid
price of $1.00 per share of Common Stock (without falling below this minimum bid
price for a period of 30 consecutive trading days), at least two market makers
and at least 300 stockholders, each holding at least 100 shares of Common Stock.
At various times from October 19, 1999 through January 6, 2000, we had failed to
meet the $35,000,000 market capitalization requirement. In addition, from
September 9, 1999 through January 6, 2000, the closing bid price of our Common
Stock was less than $1.00 per share. Since January 7, 2000, the Company has been
in compliance with the market capitalization and minimum bid price requirements.
If we are delisted by the The Nasdaq SmallCap Market, the market value of the
Common Stock could fall and holders of Common Stock would likely find it more
difficult to dispose of the Common Stock.

THE SALE OF SUBSTANTIAL SHARES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE.

         As of March 1, 2000, we had approximately 89,677,000 shares of Common
Stock outstanding. All shares under the Class C Preferred Stock Agreement had
been converted as of January 31, 2000. We could issue approximately an
additional 17,078,000 shares of Common Stock upon the exercise of outstanding
options and warrants at an average exercise price of $1.73 for proceeds of up to
approximately $29,545,000.

         During June 1998, we secured access to $20,000,000 under a Common Stock
Equity Line ("Equity Line") with two institutional investors, expiring in June
2001. Under the terms of the Equity Line, the Company may, in its sole
discretion, and subject to certain restrictions, periodically sell ("Put")
shares of the Company's Common Stock for up to $20,000,000. Unless an increase
is otherwise agreed to, $2,250,000 of Puts can be made every quarter, subject to
share issuance volume limitations identical to the share resale limitations set
forth in Rule 144(e). If the Company is able to access funds under the Equity
Line, the Company had $5,413,000 available for future Puts. Future Puts under
the Equity Line are priced at a discount equal to the greater of $0.20 or 17.5%
off the lowest closing per share bid price during the ten trading days
immediately preceding the date on which such shares are sold to the
institutional investors. At the time of each Put, the investors will be issued
warrants, exercisable only on a cashless basis and expiring on December 31,
2004, to purchase up to 10% of the amount of Common Stock issued to the investor
at the same price as the purchase of the shares sold in the Put. If we are able
to draw upon the Equity Line, we may issue up to approximately an additional
794,000 shares of Common Stock (assuming a market price of our Common Stock of
$10.00 per share) at our sole option, from time to time, in exchange for an
aggregate purchase price of $5,413,000, which includes commission shares and
warrants equal to 10% of the shares of Common Stock issued under such agreement,
which must be exercised on a cashless basis only.

         The exercise price of outstanding options and warrants and the purchase
price for the shares of Common Stock and warrants to be issued under the
Regulation D Common Stock Equity Line Subscription Agreement are at a
significant discount to the market price. The sale and issuance of these shares
of Common Stock, as well as subsequent sales of shares of Common Stock in the
open market, may cause the market price of the Common Stock to fall and might
impair our ability to raise additional capital through sales of equity or
equity-related securities, whether under the Regulation D Common Stock Equity
Line Subscription Agreement or otherwise.

OUR HIGHLY VOLATILE STOCK PRICE AND TRADING VOLUME MAY ADVERSELY AFFECT THE
LIQUIDITY OF THE COMMON STOCK.

         The market price of the Common Stock, and the market prices of
securities of companies in the biotechnology industry generally, has been highly
volatile and is likely to continue to be highly volatile. Also, the trading
volume in the Common Stock has been highly volatile, ranging from as few as
76,000 shares per day to as many as 29 million shares per day over the past
year, and is likely to continue to be highly volatile. The market price of the
Common Stock may be significantly impacted by many factors, including
announcements of technological innovations or new commercial products by us or
our competitors, disputes concerning patent or proprietary rights, publicity
regarding actual or potential medical results relating to products under
development by us or our competitors and regulatory developments and product
safety concerns in both the United States and foreign countries. These and other
external factors have caused and may continue to cause the market price and
demand for the Common Stock to fluctuate substantially, which may limit or
prevent investors from readily selling their shares of Common Stock and may
otherwise negatively affect the liquidity of the Common Stock.

OUR BUSINESS MAY BE ADVERSELY AFFECTED IF OUR COMPUTER SYSTEMS AND THE COMPUTER
SYSTEMS OF OUR SUPPLIERS ARE NOT YEAR 2000 COMPLIANT.

         In prior years, the Company discussed the nature and progress of its
plans to become Year 2000 ready. In late 1999, the Company completed its
remediation and testing of systems. As a result of those planning and
implementation efforts, the Company experienced no significant disruptions in
mission critical information technology and non-information technology systems
and believes those systems successfully responded to the Year 2000 date change.
The Company expensed less than $50,000 in connection with remediating its
systems. The Company is not aware of any material problems resulting from Year
2000 issues, its internal systems, or the products and services of third
parties. The Company will continue to monitor its mission critical computer
applications and those of its suppliers and vendors throughout the year 2000 to
ensure that any latent Year 2000 matters that may arise are addressed promptly.


ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
- -------  ----------------------------------------------------------

         A significant change in interest rates would not have a material
adverse affect on the Company's financial position or results of operations due
to the amount of cash on hand at January 31, 2000, which consists of highly
liquid investments, and as the Company's debt instruments have fixed interest
rates and terms. In addition, the Company does not invest in derivative
instruments.


                           PART II OTHER INFORMATION


ITEM 1.  LEGAL PROCEEDINGS.
- -------  ------------------

         On March 18, 1999, the Company was served with notice of a lawsuit
filed in Orange County Superior Court for the State of California (Superior
Court) by a former employee alleging a single cause of action for wrongful
termination. The Company believes this lawsuit is barred by a severance
agreement and release signed by the former employee following his termination
and the Company is defending the action. On September 13, 1999, the Superior
Court granted Techniclone a Motion for Summary Judgement and the Company was not
obligated for any damages. On November 12, 1999, a Notice of Entry of Judgement
was filed by the Superior Court. Subsequently, the former employee appealed the
Summary Judgement. The Company will continue to defending the action.


ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS.
- -------  ------------------------------------------

         The following is a summary of transactions by the Company during the
quarterly period commencing on November 1, 1999 and ending on January 31, 2000
involving issuance and sales of the Company's securities that were not
registered under the Securities Act of 1933, as amended (the "Securities Act").

         On various dates during the quarter ended January 31, 2000, the Company
issued an aggregate of 2,683,910 shares of the Company's Common Stock to the two
institutional investors and the placement agent under the Equity Line, for an
aggregate purchase price of $675,000, pursuant to an Equity Line draw and also
issued warrants to the two institutional investors and placement agent to
purchase up to 268,389 shares of Common Stock, which warrants are immediately
exercisable on a cashless basis only and expire on December 31, 2004.

                                       27
<PAGE>

         On various dates during the quarter ended January 31, 2000, the Company
issued an aggregate of 276,552 shares of the Company's Common Stock to two
institutional investors upon the cashless exercise of 360,630 warrants issued
under the Equity Line.

         On various dates during the quarter ended January 31, 2000, the Company
issued to three unaffiliated investors an aggregate of 261,934 shares of the
Company's Common Stock upon conversion of 91 outstanding shares of the Company's
5% Adjustable Convertible Class C Preferred Stock (the "Class C Stock"). Upon
conversion of the 91 shares of Class C Stock, the Company issued warrants to
such investor to purchase up to an aggregate of 65,483 shares of the Company's
Common Stock at an exercise price of $0.6554 per share.

         On various dates during January 2000, the Company issued 2,000,000
shares of common stock and warrants to purchase up to 2,000,000 shares of common
stock at an exercise price of $0.25 per share to two affiliated investors under
an Investment Agreement dated January 6, 2000 in exchange for $500,000.

         On various dates during the quarter ended January 31, 2000, the Company
issued to 120,455 shares of common stock to five private placement investors
upon the exercise of 120,455 warrants at an exercise price of $1.00 per share.
The warrants were issued in conjunction with a private placement entered into in
April 1998.

         The issuances of the securities of the Company in the above
transactions were deemed to be exempt from registration under the Securities Act
by virtue of Section 4(2) thereof or Regulation D promulgated thereunder, as a
transaction by an issuer not involving a public offering. The recipient of such
securities either received adequate information about the Company or had access,
through employment or other relationships with the Company, to such information.

                  (b) ASSIGNMENT. With the exception of the Existing Licenses
described in Section 2.02 below, Techniclone assigns to Schering all its right,
title and interest under all agreements (the "Third Party Agreements") with
Third Parties relating in any way to this Agreement and existing as of the date
hereof. Such agreements are listed on Exhibit A-2 hereto. Notwithstanding the
foregoing, Techniclone shall retain the right to conduct Development and related
activities and to manufacture and have manufactured the Product to the extent
specifically provided for in this Agreement. Techniclone agrees to use
commercially reasonable efforts to cause the applicable Third Parties to assign
the Third Party Agreements to Schering.

     Section 2.02 EXISTING LICENSES. The licenses granted under Section 2.01
include sublicenses of Third Party technology existing on the Effective Date and
licensed to Techniclone. A list of all such agreements as of the Effective Date
is attached hereto as Exhibit C, true, correct and complete copies of which have
been provided to Schering prior to the Effective Date. Any royalties payable to
Third Parties pertaining to technology discussed in the previous sentence shall
be paid by Techniclone, and, if not so paid, may be paid by Schering and offset
or deducted from royalty payments under Section 6.01. From time to time at
Schering's request, Techniclone will use its commercially reasonable efforts to
obtain a consent (a "CONSENT") from existing licensors and other contractual
counterparties with Techniclone. Such Consent shall contain the agreement of
such licensor or counterparty to (i) give reasonable written notice to Schering
prior to terminating the underlying license or contract, (ii) provide Schering a
reasonable period to cure any default under such license or contract, and (iii)
permit Schering or one or more of its Affiliates to assume Techniclone's
obligations thereunder as assignee of Techniclone's rights thereunder, in each
case at Schering's option.

     Section 2.03 VTA TECHNOLOGY. Techniclone has confirmed to Schering its
willingness to enter into a License and Development Agreement in respect of the
VTA Technology in accordance with the terms set out in Exhibit D (the "Proposed
Offer"). Techniclone hereby undertakes, at Schering's request, to enter into
good faith negotiations and to use all reasonable efforts to negotiate and
conclude a License and Development Agreement in respect of the VTA Technology in
accordance with such terms within thirty (30) days of the Effective Date. During
such thirty (30) day period, Techniclone will not license or dispose of any
rights to the VTA Technology to any Third Party, and will permit Schering to
conduct such reasonable due diligence as Schering believes to be appropriate. In
the event that during the thirty (30) day period Schering believes that
additional time is necessary to conclude a License and Development Agreement in
respect of the VTA Technology, then Schering shall so notify Techniclone
pursuant to Section 14.05, in which case the time period shall be extended by
thirty (30) days, and following Techniclone's receipt of the notice from
Schering, Schering and Techniclone shall be bound by the terms set out on
Exhibit D.

         If the thirty (30) day (or sixty (60) day if extended by Schering)
period expires without the Parties having concluded a License and Development
Agreement in respect of the VTA Technology, they shall observe the following
procedure:

                (i) Techniclone shall have the right to conclude a definitive
       agreement for the rights to the VTA Technology with a Third Party on
       terms on the whole materially more favorable to Techniclone than the
       Proposed Offer.



                                       12


<PAGE>

                (ii) In the event that within one (1) year of the Effective Date
       Techniclone desires to conclude a definitive agreement with a Third Party
       for the VTA Technology on terms equivalent to or materially less
       favorable to Techniclone than the Proposed Offer, then Techniclone shall
       submit such terms to Schering in writing pursuant to Section 14.05 (the
       "New Proposed Offer"). Techniclone need not disclose to Schering the
       identity of the Third Party. Schering shall then respond in writing to
       Techniclone within ten (10) days after receipt of such New Proposed Offer
       notice indicating whether Schering desires to commence negotiations with
       respect to same, and if Schering so indicates its desire to commence such
       negotiations, Schering shall have the right to cause Techniclone to enter
       into negotiations for thirty (30) days (or such longer period as the
       Parties may agree), and Techniclone's rights shall be determined
       accordingly.

                (iii) Provided Techniclone has complied with its obligations set
       forth in this Section 2.03, then following the first anniversary of the
       Effective Date Techniclone shall thereafter be relieved of its
       obligations set forth in this Section 2.03.

     Section 2.04 CREDIT FOR ONCOLYM PAYMENTS. In the event that Schering and
Techniclone conclude a definitive agreement concerning Techniclone's VTA
Technology pursuant to the first paragraph of Section 2.03 pursuant to
negotiations commenced prior to the expiration of the sixty day period referred
to therein, and the Development of Oncolym ceases pursuant to Article XII
without Oncolym being marketed in the United States or Europe, then Schering
shall be entitled to a credit under the definitive agreement concerning the VTA
Technology (i) for the initial payment of [...***...] paid by Schering to
Techniclone pursuant to Section 4.01 of this Agreement, and (ii) for any
Milestone Payments paid by Schering to Techniclone pursuant to Section 4.02 of
this Agreement.

     Section 2.05 ORPHAN DRUG ACT.

                  To the fullest extent permitted by law:

                  (a) Promptly following the Effective Date, Techniclone shall
transfer to Schering legal title to and possession of any and all Orphan Drug
Act petitions and other requests for designation by FDA of the Product as an
orphan drug, and/or any and all Orphan Drug Act designations by FDA of the
Product as an orphan drug. The Parties confirm that Schering will have the right
to claim and use any taxation credits, deductions or other benefits available as
a result of Orphan Drug Act designation by FDA of the Product, or a grant of
marketing exclusivity by FDA for the Product pursuant to the Orphan Drug Act.

Techniclone representatives in meetings with governmental authorities as
reasonably requested by Schering, and subject to the availability of Techniclone
personnel. Schering shall keep Techniclone apprised of its progress in obtaining
Orphan Drug Act exclusivity and any other marketing exclusivity that becomes
available in the United States and any other country of the Territory. Schering
shall be the legal and beneficial owner of Orphan Drug Act exclusivity or any
other marketing exclusivity obtained in regard to any Product in the United
States or any other country of the Territory.

                      (vi) subject to Section 3.06, evaluate any proposal to
                      contract with any Third Party to perform any Development
                      activities.

                  (c) LIMITATION ON JDC AUTHORITY. Notwithstanding the creation
of the JDC, each Party to this Agreement shall retain the rights, powers and
discretion granted to it hereunder, and the JDC shall not be delegated or vested
with any such rights, powers or discretion unless such delegation or vesting is
expressly provided for herein or the Parties expressly so agree in writing. The
JDC shall not have the power to amend or modify this Agreement, which may be
amended or modified only as provided in Section 14.12.

                  (d) RESOLUTION OF DISPUTES. If the JDC cannot reach a
unanimous decision with respect to the Development matters delegated to it
within ten (10) days then the disputed matter shall be promptly referred to a
senior manager of each Party designated by such Party for resolutions. If the
senior managers are unable to resolve such matter within ten (10) days after one
Party notifies the other of its desire to have the matter referred to such
senior managers, the decision of Schering's senior manager shall control.
Schering's initial senior manager designee is the head of Strategic Unit
Therapeutics for Schering's U.S. Affiliate, and Techniclone's Chief Executive
Officer.

                  (b) The Development of the Product shall be governed by a
development plan and budget ("DEVELOPMENT PLAN AND BUDGET"), which shall provide
for Development of the Product in the Territory and, together with updates,
shall be updated, amended, supplemented and otherwise modified from time to time
by the JDC. The Parties have agreed upon and approved the Initial Development
Plan and Budget which is attached hereto as Exhibit B.

                  (c) With respect to the Development of additional indications
for the Product, the Development Plan and Budget for each such additional
indication shall be proposed by the JDC and agreed between the Parties, and each
subsequent Development Plan and Budget for each such additional indication shall
be proposed by the JDC and submitted to the Parties for review and approval.
Anything in the previous sentence notwithstanding, Schering shall have the right

     Section 3.03 Clinical Development Applications and Drug Approval
                  Applications.

                  (a) CLINICAL STUDIES. Except in the case of Existing Trials
Schering shall be responsible for preparing, filing and prosecuting applications
for permission to conduct Clinical Development in such countries of the
Territory which require such applications to be filed and wherein Schering, in
good faith and in the exercise of reasonable business judgment, determines it is
commercially reasonable to do so. With respect to the United States and any
other country where Techniclone has such an application on file with appropriate
regulatory authorities, Techniclone shall transfer such application to Schering
promptly following the request of Schering PROVIDED that, from and after the
Effective Date, Schering shall have authority and control with respect to any
such applications (and prior to the transfer to Schering, all communications and
interactions with regulatory authorities by Techniclone with respect to such
applications shall be reviewed and approved in advance by Schering).

                  (b) DRUG APPROVAL APPLICATIONS. Techniclone will use its
reasonable best efforts to schedule as soon as is practical, a meeting with the
FDA (the "Conversion Meeting") for the purpose, INTER ALIA, of extending the
Existing Trial into a Phase III Clinical Trial. Schering shall be responsible
for preparing, filing, and prosecuting Drug Approval Applications and seeking
Regulatory Approvals for the Product in all countries in the Territory wherein
Schering, in good faith and in the exercise of reasonable business judgment,
determines it is commercially reasonable to do so, including preparing all
reports necessary as part of a Drug Approval Application. All such Drug Approval
Applications shall be filed in the name of Schering, and a copy of each such
Drug Approval Application shall be promptly provided to Techniclone. In
connection with all Drug Approval Applications being prosecuted by Schering
under this Section 3.03, Schering agrees to provide Techniclone with a copy
(which may be wholly or partly in electronic form) of all filings to regulatory
agencies that it makes hereunder within thirty (30) days after written request
by Techniclone, at no cost to Techniclone.

                  (c) COOPERATION. The Parties shall consult and cooperate
(including in the case of Techniclone providing such commercially reasonable
assistance as Schering shall reasonably request) in the preparation of each
regulatory submission and in obtaining and maintaining Regulatory Approvals
within the Territory, PROVIDED, HOWEVER, that except with regard to Existing
Trials, prior to and following approval of a Drug Approval Application, Schering
shall be solely responsible for interactions with regulatory authorities
throughout the Territory. Subject to the foregoing, Schering shall provide
Techniclone and Techniclone shall provide Schering (until transfer of
applications for permission to conduct Clinical Development, and thereafter
solely in regard to the Existing Trials) with reasonable advance notice of any
scheduled meeting with the FDA, EMEA or any other regulatory authority in a
major regulatory jurisdiction, relating to any Drug Approval Application, and
Techniclone or Schering, as applicable, shall have the right to participate in
any such meeting. In the event that any regulatory agency threatens or initiates
any action to remove a Product from the market in any country in the Territory,
Schering shall notify Techniclone of such communication within two business days
of receipt by Schering. As between Parties, Schering shall be the legal and
beneficial owner of all Drug Approval Applications and related approvals in the
Territory.

Territory pursuant to an approved Development Plan and Budget for the Product
shall be shared by the Parties in the Territory in the manner as set forth in
this Section 3.04. Each Party shall calculate and maintain records of
Development Expenses incurred by it in accordance with procedures to be agreed
upon between the Parties, which shall include an appropriate procedure for
classifying Development Expenses as Existing Trial Expenses, Preclinical
Development Expenses, Clinical Development Expenses and CMC/Manufacturing
Expenses. Accounting by Schering for Development Expenses shall be consistent
with International Accounting Standards, consistently applied. Accounting by
Techniclone for Development Expenses shall be consistent with Generally Accepted
Accounting Principles, consistently applied. Each Party shall report quarterly
to the other Party on its Development Expenses, with such reports to be
submitted within thirty (30) days after the end of each calendar quarter. At the
end of each calendar year the Parties shall assess the Development Expenses
incurred and documented by each Party. In the event that either Party disagrees
with the assessment, then the Chief Financial Officers of Techniclone and
Schering's U.S. Affiliate shall meet and attempt to resolve the disagreement. If
the Chief Financial Officers are unable to resolve the disagreement, then it
shall be resolved in the same manner as an Audit Disagreement pursuant to
Section 11.03(b). Each Party shall also have the right to audit the Development
Expenses reported by the other Party pursuant to Section 11.03.

                  (b) SHARING OF DEVELOPMENT EXPENSES.

                      (i) PRECLINICAL DEVELOPMENT EXPENSES. All Preclinical
                      Development Expenses incurred after the Effective Date up
                      to $500,000 shall be borne by Techniclone; Preclinical
                      Development Expenses incurred after the Effective Date in
                      excess of $500,000 shall be borne fifty percent (50%) by
                      Schering and fifty percent (50%) by Techniclone.

                      (ii) CLINICAL DEVELOPMENT EXPENSES. Schering shall be
                      responsible for eighty percent (80%) of all Clinical
                      Development Expenses incurred after the Effective Date for
                      Products in the Territory, and Techniclone shall be solely
                      responsible for the remaining twenty percent (20%) of such
                      Clinical Development Expenses.

                      (iii) EXISTING TRIAL EXPENSES. Existing Trial Expenses
                      incurred after the Effective Date shall be borne twenty
                      percent (20%) by Techniclone and eighty percent (80%) by
                      Schering. Each Party shall bear one hundred percent (100%)
                      of its Internal Costs relating to an Existing Trial.
                      Techniclone shall complete all Existing Trials and
                      promptly provide Schering with all data and results from
                      the Existing Trials.

                      If the FDA confirms that an Existing Trial may be extended
                      to constitute a Phase III Clinical Trial, all Clinical
                      Development Expenses incurred in respect of that Phase III
                      Clinical Trial after both of the following events have
                      occurred shall be shared between the Parties in accordance
                      with (ii) above: (A) the decision of the FDA is confirmed
                      in writing; and (B) the dosing of the first patient under
                      the amended protocol converting the trial to a Phase III
                      Clinical Trial.

<PAGE>


                      (iv) CMC/MANUFACTURING EXPENSES. Techniclone shall be
                      responsible for all CMC/Manufacturing Expenses, except for
                      certain capital costs as described in Section 7.11.
                      Without limiting in any manner Techniclone's obligations
                      hereunder, if so requested by Techniclone, and subject to
                      availability of Schering personnel, Schering agrees to
                      provide reasonable advisory/consultancy input to
                      Techniclone with respect to CMC/Manufacturing at no cost
                      to Techniclone.

                  (c) PAYMENT. Each Party shall pay to the other Party its share
of Development Expenses within forty-five (45) days of its receipt of each
report referred to in Section 3.04(a) to the extent required pursuant to the
terms of Section 3.04(b).

     Section 3.05 USE OF FUNDS. As of the Effective Date, Techniclone intends to
utilize the initial payment specified in Section 4.01 and the Milestone Payments
payable pursuant to Section 4.02 for Development Expenses and to fulfill any
manufacturing obligations it may have hereunder.

     Section 3.06 Right to Engage Third Parties.

                  (a) Subject to the advance written approval of Schering,
Techniclone shall be entitled to contract with Third Parties to perform any
Development activities. Techniclone shall notify Schering in writing thirty (30)
days prior to entering into any contract with a Third Party to perform any
Development activities where such Third Party contract has not been unanimously
approved by the JDC. During the thirty (30) day period following such notice
from Techniclone, Schering shall have the right to (i) offer to perform itself
such Development activities or (ii) propose an alternative Third Party to
perform such Development activities. If Schering decides to offer to perform
itself such Development activities or to propose an alternative Third Party to
perform such Development activities, it shall notify Techniclone in writing
during such thirty (30) day period and shall include with such notice the terms
of its offer to perform such Development activities or the identification of
such alternative Third Party or the terms of the proposal for such alternative
Third Party to perform such Development activities, as the case may be.
Techniclone shall have no obligation to accept such offer or proposal, but shall
consider such offer or proposal in good faith and negotiate towards entering
into an agreement with Schering or the alternative Third Party proposed by
Schering if Schering's offer or proposal and the capabilities of Schering or
such alternative Third Party, as the case may be, are equivalent to those of the
Third Party proposed by Techniclone. All other things being equal, Schering or
its alternative Third Party shall be the preferred provider of such Development
activities, and Techniclone shall accept Schering's offer or proposal if it is
not materially more expensive or otherwise materially less beneficial than the
offer of the Third Party proposed by Techniclone.

                  (b) In the event that Schering shall not exercise its right
pursuant to Section 3.06(a) to offer to perform itself such Development
activities or to propose an alternative Third Party to perform such Development
activities, or if Techniclone shall have failed to accept any such offer or
proposal by Schering and such offer or proposal is not materially more expensive
or otherwise materially less beneficial than the offer of the Third Party
proposed by Techniclone, Techniclone shall not use any Third Party to perform
any Development without the prior written approval of Schering (which will not
be unreasonably withheld).

<PAGE>


                  (c) Each contract related to the Development or
Commercialization of any Product entered into by Techniclone shall expressly
provide for the automatic assignment of such contract to Schering at Schering's
option upon written notice to such Third Party not more than one hundred eighty
(180) days following the termination of this Agreement for any reason, other
than a termination by Schering pursuant to Section 12.02(a).

     Section 3.07 SCHERING STEP-IN RIGHTS. Without prejudice to any other
remedies available to Schering under this Agreement or at law, if Techniclone
materially fails to carry out the reasonable Development tasks allocated to it
under this Agreement in accordance with the time lines and other conditions
allocated to it under the Development Plan and Budget and this Agreement
generally, Schering may, after forty-five (45) days prior written notice to
Techniclone, undertake that particular task ("Work") and complete it at its own
expense if Techniclone has not at such time begun to carry out such Work in a
manner reasonably likely to cure its default. Schering shall be entitled to
commercially reasonable cooperation and assistance from Techniclone to
accommodate its efforts, including assignment to Schering of sponsorship of

     SECTION 4.03 ADDITIONAL INDICATIONS. In the event that Techniclone wishes
to develop the Product for indications other than those described in the
Existing Trials or agreed upon by the Parties in the JDC, and Schering does not
object to such development, Techniclone may carry out such development at its
own risk and expense. Prior to any proposal of the Product for any such
additional indications, the Parties agree to negotiate, in good faith (without
any obligation to conclude) an agreement regarding separate initial payments,
royalties and milestone payments for such additional indications, as have been
funded, or will be funded, by Techniclone pursuant to this Section 4.03. For the
avoidance of doubt, the Parties expressly agree that for any additional
indications, with respect to which any portion of the development is funded by
Schering, Techniclone shall not be entitled to any milestone or initial payments
(but only to the royalties specified in Article VI), nor shall there be any
requirement to so negotiate. Techniclone may not develop, commercialize, sell,
license or dispose of any right, title or interest in and to such additional
indications without Schering's written consent, which may be withheld by
Schering in its discretion.

                                -----------------

     Section 5.01 SCHERING AS SOLE MARKETING PARTY. Schering shall have the
exclusive right to Commercialize the Product (either by itself or through its
Affiliates or sublicensees) in the Territory.

     Section 5.02 COMMERCIALIZATION EFFORTS. Schering agrees to use commercially
reasonable efforts with respect to the Commercialization of the Product
throughout the Territory as provided hereunder. Such commercially reasonable
efforts shall be consistent with the efforts used by Schering in preparing
commercialization plans and budgets and commercializing its own pharmaceutical
products. Without limiting the generality of the foregoing, Schering shall
determine the pricing and marketing strategy for the Product in its sole
discretion. Within 180 days after the execution hereof, Schering will present to
Techniclone a preliminary Commercialization plan outlining pre-launch
strategies, activities and plans related to the proposed Commercialization of
Oncolym, in the United States and Europe, together with projected five year
sales forecasts. Any such plans and forecasts provided to Techniclone by
Schering shall not be binding on Schering. Schering shall not be obligated to
Commercialize the Product in any country where Schering does not believe it
would be commercially reasonable to do so.

     Section 5.03 COMPETING PRODUCTS. On a country-by-country basis, in the
event that after the Regulatory Approval of the Product Schering desires to
continue the sale or commence the sale, as the case may be, of a Competing
Product then at Schering's option one of the following conditions shall apply:

                      (i) Schering shall return to Techniclone marketing rights
                      to the Product in the applicable country; or

                      (ii) Schering shall pay Techniclone a royalty of
                      [...***...] on Schering's Net Sales of the Competing
                      Product in the country in question for as long as Schering
                      continues to sell both the Product and the Competing
                      Product and to pay royalties on sales of the Product in
                      the country in question in accordance with the terms
                      hereof.

The foregoing conditions shall not be applicable to the sale by Schering of a
Competing Product if in the applicable country Schering has sublicensed
marketing rights to Oncolym to a party that is not an Affiliate of Schering; and
such sub-licensee is not selling a Competing Product. The restrictions set forth
in this Section 5.03 shall apply in Europe only to the extent permitted by the
Treaty of Rome.

     Section 5.04 TECHNICLONE RESTRICTIONS.

                  Outside of Europe Techniclone shall not make, use, sell or
permit, or cooperate with any Third Party in the manufacture use or sale of a
therapeutically capable radioisotope attached to any monoclonal antibody which
recognizes any antigen on the surface of B-cells. Within Europe, Techniclone's
reservation of diagnostic rights to the Antibody and/or the Product shall not
permit Techniclone to use, make or sell, or to permit or cooperate in the use,
manufacture or sale of the Antibody and/or the Product, in whole or in part, for
purposes falling within the Field.

                                    ROYALTIES
                                    ---------

     Section 6.01 ROYALTIES. GENERAL. In further consideration of the rights and
licenses granted to Schering under Article II of this Agreement, Schering shall
pay to Techniclone a royalty equal to [...***...] of Net Sales of the Product in
the Territory (the "ROYALTY PERCENTAGE").

                  (b) ROYALTY TERM. Except where expressly provided otherwise in
this Agreement, and subject to Section 6.01(c) below, all royalties to a Party
shall be paid, on a country-by-country basis, from the date of the First
Commercial Sale of the Product in a particular country until the later (the
"Royalty Expiration Date") of (i) [...***...] from the First Commercial Sale in
such country and (ii) the last to expire of any Techniclone Patent which
includes a Valid Claim in such country; PROVIDED, HOWEVER, that if the Product
is sold in any country in which Techniclone does not have a Valid Claim which
would prevent the sale of a generic form of such Product, the royalty obligation
set forth in Section 6.01(a) with respect to Net Sales attributable to the sale
of the Product in such country shall be reduced by [...***...] of the royalty
that would otherwise be payable with respect to Net Sales attributable to the
sale of the Product in such country, until Techniclone is granted a Valid Claim
in such country.

                  (c) GENERIC. The royalty reduction of [...***...] described in
Section 6.01(b) above shall only apply in any country of the Territory if a
generic form of the Product is actually sold in such country.

                  (d) DISCONTINUANCE. Subject to the provisions of Article XII,
Schering may discontinue Commercialization of the Product at any time, in any
country, and on a country-by-country basis.

                  (e) LICENSE FOLLOWING EXPIRATION. After the Royalty Expiration
Date, Schering shall thereafter have an exclusive (even as to Techniclone),
paid-up license to Techniclone Know-How to make, have made, use, sell, offer for
sale, have sold and import the Antibody and/or Product in that country,
PROVIDED, HOWEVER, that if Schering elects not to continue paying royalties as
provided herein in subsection (g) below at any time after the Royalty Expiration
Date, such license shall be non-exclusive.

                  (f) NON-EXTENSION OF EXISTING TRIALS. If the FDA does not
consent to an extension of the Existing Trials as a Phase III Clinical Trial by
[...***...], then the royalty specified in Section 6.01(a) shall be reduced by
[...***...] (e.g., from [...***...]).

                  (g) ROYALTY EXTENSION. Schering, at its sole discretion, may
elect to continue paying royalties under Section 6.01(a)-(f) after the Royalty
Expiration Date PROVIDED Schering gives Techniclone at least [...***...] months
notice prior to the then scheduled Royalty Expiration Date, and further PROVIDED
, that the applicable royalty will be [...***...] (subject to reduction under
subsections (b) and (f)). In the event that Schering thereafter elects to
terminate paying royalties to Techniclone, Schering shall provide [...***...]
months advance notice to Techniclone, in which case Techniclone shall have the
right to terminate its manufacturing obligations under Article VII on
[...***...] months advance notice to Schering. Notwithstanding anything to the
contrary contained herein, Techniclone shall not be obligated to continue to
perform its manufacturing obligations hereunder beyond the Royalty Expiration
Date PROVIDED that Techniclone uses its reasonable best efforts to have its
manufacturing contracts with Third Parties related to this Agreement (and its
rights and obligations thereunder) assigned and transferred to Schering or a
Third Party designated by Schering, in which case, the provisions of Section
7.12 hereof shall apply; and PROVIDED further, that, if Schering or its Third
Party designee does not duly assume such contracts (and the rights and
obligations thereunder) and Techniclone is not otherwise able to so assign and
transfer same to Schering or its Third Party designee, Techniclone shall have
the right to terminate its manufacturing obligations as of or at any time
following the Royalty Expiration Date on [...***...] months prior notice to
Schering.

     Section 6.02 ROYALTY REPORTS AND PAYMENTS. Schering shall make royalty
payments to Techniclone quarterly within sixty (60) days after the end of each
calendar quarter in which Net Sales occurred. A report summarizing the Net Sales
of the Products during the relevant quarter on a country-by-country basis shall
be delivered to Techniclone within sixty (60) days following the end of each
calendar quarter for which royalties are due.

     Section 6.03 PAYMENTS; INTEREST. Any payments due under this Agreement
shall be due on such date as specified in this Agreement and, in the event such
date is a day on which commercial banks are not authorized to conduct business
in either Tustin, California, New York, New York or Berlin, Germany, then the
next succeeding business day, and shall be made by wire transfer to a designated
bank account of the receiving Party.

                  Any failure by a Party to make a payment within five days
after the date when due shall obligate such Party to pay interest to the
receiving Party at a rate per annum equal to the prime rate as quoted in the
Eastern edition of the WALL STREET JOURNAL as of the date such payment is due
and, in the event such a rate is not quoted on such date then on the immediately
preceding date such rate is quoted, such interest due and payable upon tender of
the payment otherwise due and payable.

     Section 6.04 TAXES. The Party receiving royalties shall pay any and all
taxes levied on account of royalties it receives under this Agreement. If laws
or regulations require that taxes be withheld, the selling Party will (i) deduct
those taxes from the remittable royalty, (ii) timely pay the taxes to the proper
taxing authority, and (iii) send proof of payment to the other Party within
thirty (30) days of receipt of confirmation of payment from the relevant taxing
authority. The selling Party agrees to make all lawful and reasonable efforts to
minimize such taxes to the other Party.

     Section 6.05 PAYMENTS TO OR REPORTS BY AFFILIATES. Any payment required
under any provision of this Agreement to be made to either Party or any report
required to be made by any Party shall be made to or by an Affiliate of that

entity without relieving such party from responsibility for such payment or
report.

     Section 6.06 PAYMENT CURRENCY. Payments by Schering under this Agreement
shall be paid to Techniclone in U.S. dollars by wire transfer of immediately
available funds to an account at a commercial bank designated by Techniclone
pursuant to this Article VI. Where payments are based on Net Sales in countries
other than the United States, the amount of such Net Sales expressed in the
currency of each country shall be converted first into Deutsche Marks, or if the
Deutsche Mark shall have been replaced by the Euro, into Euros, and then into
U.S. dollars at the average exchange rate (calculated at the average of the
"bid" and "asked" exchange rate) for the applicable quarter; PROVIDED, HOWEVER,
that the conversion of the currency in question into Deutsche Marks or Euros
prior to conversion into U.S. dollars shall be for calculation purposes only,
and no additional fee or commission will be incurred as a consequence of the
multiple currency conversions. In determining the average exchange rate for any
quarter, the standard shall be the exchange rate quoted by the Frankfurt Fixing
or any appropriate successor rate fixing procedure then in effect between
European First Class Banks for the applicable currency at 1:00 p.m. on the last
business day of the applicable quarter. If there is no Frankfurt Fixing or
appropriate successor rate fixing procedure in effect as of any date of
determination, the Parties shall agree on another reference rate.

year. If following the close of a calendar year, Techniclone determines that
actual Treatments shipped in such calendar year failed to achieve the threshold
required for the Price charged to Schering, then Techniclone will recalculate
the amount owed by Schering to Techniclone and invoice Schering for such amount.
If Schering agrees with the Techniclone calculation, then Schering shall pay the
Techniclone invoice promptly following receipt. If Schering disagrees with the
Techniclone calculation, then the disagreement shall be resolved as if it was an
Audit Disagreement pursuant to Section 11.03(b).

                  (b) In the event that Techniclone's Price is below the
applicable maximum set forth in Section 7.10(a)(i), (ii), or (iii), then
Schering, in addition to paying Techniclone the Price, shall pay Techniclone a
sum equal to [...***...] of the difference between the Price and the applicable
maximum set forth in Section 7.10(a).

                  (c) Schering shall make payments for Packaged Products shipped
to Schering's customers which comply with the Techniclone warranty set forth in
Section 7.09 within [...***...] days of receipt by Schering of Techniclone's
invoice. In the event that it is later determined that Packaged Product paid for
by Schering does not comply with the specifications and the Techniclone warranty
set forth in Section 7.09, Techniclone shall replace such Packaged Product free
of charge upon Schering's demonstration of such non-compliance to the reasonable
satisfaction of Techniclone.

     Section 7.11 CONSTRUCTION OF COMMERCIAL RADIOLABELING SITES.(a) If the
Parties agree that it is necessary or desirable to construct one or more
commercial radiolabeling sites for Oncolym, then Techniclone shall be
responsible for the construction of such site or sites, subject to prior review
and approval of plans and budgets by Schering. Schering shall be responsible,
upon payment of an equal amount by Techniclone, for (i) [...***...] of the total
capitalized cost up to $[...***...] (i.e., the Schering contribution will not
exceed [...***...]) of developing the first commercial radiolabeling site for
Oncolym in the United States, Canada, Japan or Europe and Techniclone shall be
responsible for the remaining [...***...] or more of such capitalized cost; and
(ii) [...***...] of the total capitalized cost up to $[...***...] (i.e., the
Schering contribution will not exceed $[...***...]) of developing the second
commercial radiolabeling site for Oncolym in the United States, Canada, Japan or
Europe and Techniclone shall be responsible for the remaining [...***...] or
more of such capitalized cost. Neither Party will unreasonably withhold its
agreement as set forth in the first sentence of this Section 7.11. Neither Party
will withhold its agreement as set forth in the first sentence of this Section
7.11 if an additional radiolabeling site is reasonably necessary for Schering to
distribute packaged Product in the United States, Canada, Japan or Europe.

                  (b) In the event that Schering determines in its sole
discretion that one or more commercial radiolabeling sites for Oncolym are
necessary or desirable, and Techniclone reasonably withholds its agreement
pursuant to Section 7.11 (a) (for example, because the radiolabeling site
proposed by Schering is not necessary for Schering to distribute Packaged
Product in the United States, Canada, Japan or Europe), then Schering shall have
the right to arrange for the construction or use of such site or sites at its
sole expense. Techniclone shall cooperate with Schering in the establishment of
such site or sites and, subject to the availability of Techniclone personnel,
shall provide such commercially reasonable assistance as Schering
shall request. In the event that Schering establishes one or more radiolabeling
sites pursuant to this Section 7.11(b), then at the request of Schering
Techniclone agrees to enter into a supply agreement with Schering for the supply
of Schering's requirements of Antibody at a price not to exceed Techniclone's
Cost of Goods plus [...***...].

     Section 7.12 SCHERING OPTION TO TAKE OVER MANUFACTURING. Notwithstanding
anything to the contrary herein, Schering may, at any time, by delivery of
written notice to Techniclone elect to become the Manufacturing Party hereunder
either in respect of Antibody or in respect of Product. Subject to the terms of
all relevant Third Party contracts related to manufacture of the Product, such
election shall become effective on the date specified in such notice, whereupon
Techniclone will be deemed to have transferred and assigned to Schering (and
will promptly transfer to Schering) all Information regarding Techniclone
Know-How and all Third Party contracts related to manufacture of the Product. In
the event that Schering shall so elect, it shall indemnify and hold Techniclone
harmless against any non-cancelable costs, expenses or fees payable to Third
Parties that Techniclone may become subject to as a result of such termination
of manufacturing obligations. In connection with any such election Schering
shall offer to purchase from Techniclone the property, plant and equipment
dedicated by Techniclone for the manufacture of Product, as the case may be, at
a purchase price equal to the book value of such property, plant and equipment.

     SECTION 7.13 SCHERING MANUFACTURING STEP-IN RIGHTS. Without prejudice to
any other remedies available to Schering under this Agreement or at law, if
Techniclone materially fails to carry out its responsibilities regarding
CMC/Manufacturing allocated to it under this Agreement, Schering may, after
forty-five (45) days prior written notice to Techniclone, undertake the
particular task and complete it at Schering's own expense if Techniclone has not
at such time begun to carry out such task in a manner reasonably likely to cure
its default. Schering shall be entitled to commercially reasonable cooperation
and assistance from Techniclone to accommodate its efforts. All costs reasonably
incurred by Schering in carrying out such tasks will be reimbursed by
Techniclone on a quarterly basis as invoiced by Schering or may, at Schering's
option, be set off against any payments otherwise due to Techniclone under this
Agreement.

patent applications, will use its reasonable efforts to secure confidential
treatment of such Confidential Information required to be disclosed. In
addition, and with prior written notice to the other Party of each Third Party
with whom a confidential disclosure agreement is being entered into, each Party
shall be entitled to disclose, under a binder of confidentiality, Confidential

functions as is customary in the pharmaceutical industry. Where materiality of
disclosure requires a press release or other disclosure pertaining to this
agreement by one Party, the disclosing Party shall give at least two (2)
business days' advance notice to the other Party.

consent shall not be unreasonably withheld or delayed; PROVIDED, HOWEVER, that

                      interest in and to all rights to Oncolym and the
                      Techniclone Patents and Techniclone Know-How, free and
                      clear of any liens, encumbrances or rights to repurchase;
                      and

                      (x) During the term hereof, Techniclone will not grant a
                      lien on this Agreement or on any of Techniclone's rights
                      or obligations hereunder or on the Techniclone Patents or
                      Techniclone Know-How related to the Product.

WARRANTIES. Each Party hereby agrees to save, defend and hold the other Party
and its directors, officers, agents and employees harmless from and against any
and all Losses resulting directly or indirectly from the breach of any

                             INFORMATION AND REPORTS
                             -----------------------

     Section 11.01 INFORMATION AND REPORTS DURING DEVELOPMENT AND
COMMERCIALIZATION. Schering and Techniclone will disclose and make available
(subject to any confidentiality agreements or requirements of law) to each other
without charge all preclinical, clinical, regulatory, and other Information,
including copies of all preclinical and clinical reports, known by Schering or
Techniclone directly concerning the Product within the Field at any time during
the term of this Agreement. Each Party shall own and maintain its own database
of clinical trial data accumulated from all clinical trials of the Product for
which it was responsible and of adverse drug event information for the Product.
At the option of the requesting Party, such data shall be provided in a computer
readable or other electronic format by the providing Party, to the extent
available, which shall also assist in the transfer and validation of such data
to the receiving Party. Without limitation of the foregoing, each Party shall
supply to the other the Information required by the other Party and requested by
it (either as a routine practice or as a specific request) for purposes of
compliance with regulatory requirements. With respect to information concerning
Commercialization, Schering agrees to keep Techniclone regularly informed on all
post marketing activities, but shall have no obligation, except as specifically
set forth in this Agreement, to share pricing, marketing or sales information
with Techniclone.

     Section 11.02 ADVERSE DRUG EXPERIENCES; COMPLAINTS. The Parties agree to
enter into a standard operating procedure by and between the Parties to govern
the exchange of Information relating to adverse drug experiences, Product
quality, and Product complaints.

     Section 11.03 RECORDS OF REVENUES AND EXPENSES. Each Party will maintain
complete and accurate records which are relevant to revenues, costs, expenses
and payments on a country-by-country basis in the Territory under this Agreement
and such records shall be open during reasonable business hours for a period of
two (2) years from creation of individual records for examination at the other
Party's expense and not more often than once each year by a certified public
accountant selected by the other Party, or the other Party's internal
accountants unless the first Party objects to the use of such internal
accountants, for the sole purpose of verifying for the inspecting Party the
correctness of calculations and classifications of such revenues, costs,
expenses or payments made under this Agreement. Each Party shall bear its own
costs related to such audit; PROVIDED that, for any underpayments greater than
five (5) percent by Schering, Schering shall pay Techniclone the amount of
underpayment, interest as provided for in Section 6.03 from the time the amount
was due and Techniclone's out-of-pocket expenses. For any underpayments less
than five (5) percent by Schering found under this Section, Schering shall pay
Techniclone the amount of underpayment. Any overpayments by Schering will be
refunded to Schering or credited to future royalties, at Schering's election.
Any records or accounting information received from the other Party shall be
Confidential Information for purposes of Article VIII. Results of any such audit
shall be provided to both Parties, subject to Article VIII.

                  (b) If there is a dispute between the Parties following any
audit performed pursuant to Section 11.03(a), either Party may refer the issue
(an "AUDIT DISAGREEMENT") to an independent certified public accountant for
resolution. In the event an Audit Disagreement is submitted for resolution by
either Party, the Parties shall comply with the following procedures:

                      (i) The Party submitting the Audit Disagreement for
                      resolution shall provide written notice to the other Party
                      that it is invoking the procedures of this Section
                      11.03(b).

                      (ii) Within thirty (30) business days of the giving of
                      such notice, the Parties shall jointly select a recognized
                      international accounting firm to act as an independent
                      expert to resolve such Audit Disagreement.

                      (iii) The Audit Disagreement submitted for resolution
                      shall be described by the Parties to the independent
                      expert, which description may be in written or oral form,
                      within ten (10) business days of the selection of such
                      independent expert.

                      (iv) The independent expert shall render a decision on the
                      matter as soon as practicable.

                      (v) The decision of the independent expert shall be final
                      and binding unless such Audit Disagreement involves
                      alleged fraud, breach of this Agreement or construction or
                      interpretation of any of the terms and conditions hereof.

                      (vi) All fees and expenses of the independent expert,
                      including any Third Party support staff or other costs
                      incurred with respect to carrying out the procedures
                      specified at the direction of the independent expert in
                      connection with such Audit Disagreement, shall be borne by
                      each Party in inverse proportion to the disputed amounts
                      awarded to the Party by the independent expert through
                      such decision (e.g. Techniclone disputes $100, the
                      independent expert awards Techniclone $50, then each Party
                      pays 1/2 of the independent expert's costs) in all other
                      cases.

                              TERM AND TERMINATION
                              --------------------

     Section 12.01 TERM. This Agreement shall commence as of the Effective Date
and, unless sooner terminated as provided herein shall continue in effect until
such time as (i) no royalties are payable under Article VI hereunder to
Techniclone; and (ii) Techniclone's manufacturing obligations described in
Article VII shall have terminated, provided that the license granted pursuant to
Section 6.01(e) shall survive such termination.

     Section 12.02 TERMINATION AT WILL.

                  (a) Notwithstanding any other term or provision hereof
expressly or impliedly to the contrary, Schering may terminate this Agreement in
its entirety or on a country-by-country basis, and be fully released of any
obligations hereunder (except as is expressly provided for herein) as follows:

                      (i) immediately at any time if Schering determines, in its
                      reasonable judgment, that there are issues of Safety or
                      Tolerability;

<PAGE>


                      (ii) immediately if (A) the FDA requires that the Existing
                      Trials be repeated before a Phase III Clinical Trial can
                      begin; (B) the FDA requires that a new Phase II Clinical
                      Trial be conducted before a Phase III Clinical Trial can
                      begin; (C) the FDA has not allowed the commencement of a
                      Phase III Clinical Trial by [...***...]; (D) the FDA
                      Conversion Meeting does not occur by [...***...]; or (E)
                      Techniclone fails to deliver or it becomes reasonably
                      clear that Techniclone will fail to deliver in time
                      appropriate quantities of clinical supplies of Antibody,
                      Product and Packaged Product such that Clinical
                      Development is or will be delayed by a period of
                      [...***...] or more beyond the date anticipated in the
                      Development Plan.

                      (iii) upon ten days' written notice to Techniclone, if,
                      based upon data from, or the results of, the first Phase
                      III Clinical Trial of the Product, Schering determines,
                      using its reasonable judgment, that such results do not
                      support the submission of the Product for Regulatory
                      Approval based upon the criteria for Regulatory Approval
                      established at the Conversion Meeting or subsequently by
                      the FDA (the "Approval Criteria");

                      (iv) upon [...***...] written notice, given at any time
                      prior to the receipt of Regulatory Approval, if Schering
                      determines that for reasons of efficacy or risk/benefit
                      therapeutic ratio, that the Product, in Schering's
                      reasonable scientific or business discretion, is not
                      considered acceptable, applying the standard of medical
                      care and/or business judgment of major international
                      pharmaceutical companies engaged in the oncology business,
                      and taking into account the standard of medical care then
                      applicable at major international oncology treatment
                      centers;

                      (v) upon [...***...] written notice given at any time
                      prior to Regulatory Approval, for any reason;

                      (vi) at any time after Regulatory Approval, upon
                      [...***...] notice to Techniclone, for any reason; and

                      (vii) immediately if Techniclone has not concluded a
                      definitive agreement (in compliance with Section 7.01)
                      providing for a radiolabeling site for the production of
                      Product and Packaged Product [...***...].

                  (b) TERMINATION FOR MATERIAL BREACH. Failure by Schering or
Techniclone to comply with any of the respective material (which, for the
purposes hereof, shall not include Section 3.05) obligations and conditions
contained in this Agreement shall entitle the other Party to give the Party in
default notice requiring it to cure such default. If such default is not cured
within ninety (90) days after receipt of such notice, the notifying Party shall
be entitled (without prejudice to any of its other rights conferred on it by
this Agreement) to terminate this Agreement or in the event of an uncured
material breach by Techniclone, effect the rights of Schering set forth in
Section 12.02(e) by giving a notice to take effect immediately. Notwithstanding
the foregoing, in the event of a non-monetary default, if the default is not
reasonably capable of being cured within the ninety (90) day cure period by the
defaulting Party and such defaulting Party is making a good faith effort to cure
such default, the notifying Party may not terminate this Agreement, provided,
however, that the notifying Party may terminate this Agreement if such default
is not cured within one hundred eighty (180) days of such original notice of
default. The right of either Party to terminate this Agreement as hereinabove
provided shall not be affected in any way by its waiver of, or failure to take
action with respect to any previous default.

                  (c) TERMINATION FOR INSOLVENCY. In the event that one of the
Parties hereto shall go into liquidation, a receiver or a trustee be appointed
for the property or estate of that Party and said receiver or trustee is not
removed within sixty (60) days, or the Party makes an assignment for the benefit
of creditors (collectively, a "BANKRUPTCY EVENT"), and whether any of the
aforesaid Bankruptcy Events be the outcome of the voluntary act of that Party,
or otherwise, the other Party shall be entitled to terminate this Agreement (or
in the event Techniclone suffers such a Bankruptcy Event, Schering may effect
its rights described in Section 12.02(e) forthwith by giving a written notice to
Techniclone). Each Party agrees (to the extent it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim to
take the benefit or advantage of, any stay or extension law or any other law
wherever enacted, now or at any time hereafter in force, which would prohibit
the termination of this Agreement or in any way modify the effects thereof as
provided herein; and each Party (to the extent it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the other Party, but will suffer and permit the execution of every power as
though no such law had been enacted.

                  (d) EFFECT OF TERMINATION. (A) In the event that this
Agreement is terminated by Schering in one or more countries or in its entirety
in accordance with Section 12.02(a), or commercialization of the Product is
discontinued by Schering in one or more countries pursuant to Section 6.01(d),
or this Agreement is terminated by Techniclone pursuant to Section 12.02(b) in
one or more countries if Schering either fails to use commercially reasonable
efforts to enable the Product to obtain Regulatory Approval in those countries
where Schering is obligated to do so pursuant to Section 3.03(b), or fails to
Commercialize the Product in the countries where Schering is obligated to do so
pursuant to Section 5.02, and in the event that the Agreement is terminated by
either Party in its entirety in accordance with Sections 12.02(a),(b) or (c)
hereof, as applicable, subject to Section 12.02(e), Schering will with respect
to each country, as a whole, for which the termination applies:

<PAGE>

                      (i) deliver to Techniclone the Techniclone Know-How and
                      assign to Techniclone its rights in said Techniclone
                      Know-How and Techniclone Patents if any, in either case
                      relating solely to the country that is the subject of the
                      termination;

                      (ii) not use the Techniclone Know-How as long as it has to
                      be kept confidential pursuant to Article VIII hereof in
                      such country;

                      (iii) not infringe any of the Techniclone Patents in such
                      country;

                      (iv) make all payments incurred under this Agreement with
                      respect to such country prior to the effective termination
                      date;

                      (v) transfer all regulatory filings and approvals related
                      to the Product in such country to Techniclone upon
                      Techniclone's written request for same;

                      (vi) transfer to Techniclone responsibility for and
                      control of ongoing work of Schering related to the
                      Product, Affiliates and Third Parties in an expeditious
                      and orderly manner with the costs for such work assumed by
                      Techniclone as of the date of notice;

                      (vii) reconvey to Techniclone all rights to the trademark
                      for "Oncolym" granted pursuant to Section 2.01; and

                      (viii) sell to Techniclone, at any time within ninety (90)
                      days of such termination, at Techniclone's election, all
                      or any portion of the inventory of the Product owned by
                      Schering or its Affiliates which are intended for sale in
                      such country at a price equal to Schering's or its
                      Affiliate's cost for such inventory; such election shall
                      be made by Techniclone in writing and within thirty (30)
                      days of such election, Schering shall ship at
                      Techniclone's cost and direction such inventory to
                      Techniclone. Techniclone shall pay for such inventory
                      within forty-five (45) days of receipt of such inventory.

         (B) If as a result of the operation of Section 12.02(d)(A) Techniclone
has the right to Commercialize the Product in one or more countries while
Schering is Commercializing the Product in the United States or Europe, then
upon written notice from Schering, Techniclone agrees to refrain from
Commercializing the Product in any country in which such Commercialization, in
the reasonable opinion of Schering, would have a material negative impact on
Schering's Commercialization in the United States or Europe.

                  (e) EFFECT OF TERMINATION BY SCHERING PURSUANT TO SECTIONS
12.02(b) AND (c). In the event of a Bankruptcy Event or a material default
described in Sections 12.02(b) and (c) by Techniclone (which default is not
cured as provided therein), Schering may elect in lieu of terminating this
Agreement to declare the license granted pursuant to this Agreement to be
irrevocable. From the date of receipt of notice of such election, Techniclone
shall have no further rights or obligations under this Agreement, except that
Techniclone may enforce any financial obligations of Schering, including those
arising under Section 3.04, Articles IV and VI herein before or after such
election, and Schering may enforce any manufacturing and supply obligations of
Techniclone, including those arising under Section 12.02(g); PROVIDED that if
such election occurs prior to the First Commercial Sale of the Product, any
additional Development Expenses and reasonable costs incurred by Schering to
Commercialize the Product as a result of such election shall be credited against
amounts payable by Schering to Techniclone.

to:

                      A. Section 12.02(a)(i), (iii), or (iv), THEN Schering
                      shall reimburse Techniclone for [...***...] of the
                      non-cancellable Third Party Costs ("Non-cancellable
                      Costs") that Techniclone may incur after the effective
                      time of termination with respect only to clinical trials
                      underway at such effective time; PROVIDED, HOWEVER, that
                      Schering's [...***...] share of Non-cancellable Costs
                      shall not exceed $[...***...]; or

                      B. Section 12.02(a)(v), THEN Schering shall, if a Phase
                      III Clinical Trial is then underway for the Product, be
                      obligated to fund [...***...] of the costs of completing
                      all then ongoing Phase III Clinical Trials for the Product

                      payable under this subsection (B) shall not exceed
                      $[...***...].

                  (g) OBLIGATIONS OF MANUFACTURING PARTY. In the event of
termination of this Agreement pursuant to this Section 12.02 where the Party
terminating this Agreement is the Manufacturing Party, the Manufacturing Party
shall continue to provide for manufacture of the Antibody, Product and/or
Packaged Product, as applicable, to the extent provided prior to notice of such
termination, from the effective date of such termination until such reasonable
time as the Non-Manufacturing Party is able to secure an equivalent alternative
commercial manufacturing source, as requested by the Non-Manufacturing Party.

                  (h) GENERAL. Except where expressly provided for otherwise in
this Agreement, termination of this Agreement shall not relieve the Parties
hereto of any liability, including any obligation to make payments hereunder,
which accrued hereunder prior to the effective date of such termination, nor
preclude any Party from pursuing all rights and remedies it may have hereunder
or at law or in equity with respect to any breach of this Agreement nor
prejudice any Party's right to obtain performance of any obligation.

                  (c) Each indemnified Party agrees to give the indemnifying
Party prompt written notice of any Loss or discovery of fact upon which such
indemnified Party intends to base a request for indemnification under Sections
13.01(a) or (b). Each Party shall furnish promptly to the other copies of all
papers and official documents received in respect of any Loss. With respect to
any Loss relating solely to the payment of money damages and which will not
result in the indemnified Party becoming subject to injunctive or other relief
or otherwise adversely affecting the business of the indemnified Party in any
manner, and as to which the indemnifying Party shall have acknowledged in
writing the obligation to indemnify the indemnified Party hereunder, the
indemnifying Party shall have the sole right to defend, settle or otherwise
dispose of such Loss, on such terms as the indemnifying Party, in its sole
discretion, shall deem appropriate. The indemnifying Party shall obtain the
written consent of the indemnified Party, which shall not be unreasonably
withheld or delayed, prior to ceasing to defend, settling or otherwise disposing
of any Loss if as a result thereof the indemnified Party would become subject to
injunctive or other equitable relief, or any remedy other than the payment of
money which is the responsibility of the indemnifying Party. The indemnifying
Party shall not be liable for any settlement or other disposition of a Loss by
the indemnified Party which is reached without the written consent of the
indemnifying Party. The reasonable costs and expenses, including reasonable fees
and disbursements of counsel incurred by any indemnified Party in connection
with any Loss, shall be reimbursed on a quarterly basis by the indemnifying
Party, without prejudice to the indemnifying Party's right to contest the
indemnified Party's right to indemnification and subject to refund in the event
the indemnifying Party is ultimately held not to be obligated to indemnify the
indemnified Party.

                           DEVELOPMENT PLAN AND BUDGET


The following information reflect estimates only, which are not binding. The
following information is based upon current assumptions by Techniclone and is
subject to change by the Joint Development Committee (JDC) and if the
assumptions made in this document are not realized.


CLINICAL PLAN

Phase III Study Design:

The plan is for an open-label, non-randomized, multi-center, single 1311Lym-1
dose-level study in subjects with intermediate- or high-grade B-cell
Non-Hodgkin's lymphoma who have relapsed following [...***...] courses of
intensive multi-drug chemotherapy. Tumor tissue from the subjects must be
positive for Lym-1 by histology and/or localization of radioactivity with an
imaging study. Ninety subjects will be treated at up to 16 study sites. (A
subject is considered to be evaluable if he/she has received at least one course
of treatment and has had their indicator lesions measured on an x-ray CT scan
performed 4 weeks after this treatment). An imaging analysis will be performed
prior to initiation of therapy to quantitatively assess the uptake of the
radiolabeled Lym-1 antibody. All subjects who qualify for the treatment phase of
the protocol after imaging will receive therapeutic treatment with two (2) doses
of [...***...], unless: 1) the tumor progresses or 2) toxicity precludes
completion of dosing. Treatment doses will be administered at 6-week intervals
or when hematologic indices are acceptable per the protocol. The primary
endpoint in this trial will be the incidence of overall response (CR + PR), as
determined by an independent reviewer assessed across all measurable lesions. An
overall response rate of >35% will be considered evidence of efficacy. Duration
of response and survival will be the secondary endpoints.

The Parties envisage commencement of the Phase III Clinical Trial no later than
[...***...], by which date sufficient quantities of Antibody, Product and
Packaged Product of appropriate quality will be available to begin and proceed
with all reasonable diligence with and complete the Phase III Clinical Trial.

CMC MANUFACTURING

Techniclone plans to manufacture antibody at the Techniclone facility in Tustin
CA. Transition to a commercial contract facility (e.g. Schering, Lonza or
Covance) will commence at least [...***...] prior to exceeding maximum capacity
at the Techniclone facility (based upon Schering forecasts). The plan calls for
the commercial scale antibody to be available no later than [...***...] with the
following timetable/assumptions:

1. Process issues and yield optimization complete - [...***...]
2. Begin conformance lot runs - [...***...]
3. End conformance lot runs - [...***...]
4. Short term stability (last lot) - [...***...]
5. BLA submission - [...***...]

TOTAL CMC SCALEUP COSTS INCLUDING ADDITIONAL CAPITAL EQUIPMENT AND MANPOWER
(ESTIMATED) - $[...***...]

Techniclone's projections for product assume the in-house antibody production
will accommodate from [...***...] to [...***...] treatments per year depending
upon the final yield optimization. This projection does not include building
antibody inventory based on the known 2-year stability of the LYM-1 drug
substance.


RADIOLABELING

Techniclone plans on contracting with MDS Nordion (Ottawa) for manufacture and
distribution of the final Iodine-131 labeled drug product (Oncolym(R)).

The following milestones assume BLA submission in the United States in
[...***...].

1. Finalize commercial process including scale up - [...***...]
2. Finalize facility design at Nordion - [...***...]
3. Begin facility construction - [...***...]
4. Complete facility and commission - [...***...]

2.       Nordion will radiolabel [...***...] vials per batch run.

3.       The amount of unused radiolabeled vials per batch (scrap) will decrease
         as sales volume increases to the level necessary to utilize the batch
         yield.

4.       The radiolabeling facility has associated fixed costs; as volume
         increases the cost per batch is reduced thus lowering cost per dose.

         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
Delaware (the "Company"), and the undersigned subscriber executing this
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

the Securities Act of 1933, as amended (the "Act"). The Unit Shares and the

collectively as the "Securities."

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

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.

                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

                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.

capacity, has full power and authority to execute and deliver this Agreement and
each other document included herein for which a signature is required in such
capacity and on behalf of the subscribing individual, partnership, trust,
estate, corporation or other entity for whom or which Subscriber is executing

according to the laws of the state in which he or she resides.

                2.4.2 DUE AUTHORIZATION. If Subscriber is a corporation,
Subscriber is duly and validly organized, validly existing and in good corporate
standing as a corporation under the laws of the jurisdiction of its
incorporation with full power and authority to purchase the Securities to be

                2.4.4 REPRESENTATIVES. If Subscriber is purchasing in a

         3. ACKNOWLEDGMENTS Subscriber is aware that:

            3.1 RISKS OF INVESTMENT. Subscriber recognizes that an investment in
the Company involves substantial risks, including the potential loss of
Subscriber's entire investment herein. Subscriber recognizes that the Disclosure
Documents, this Agreement and the exhibits hereto do not purport to contain all
the information which would be contained in a registration statement under the
Act;

            3.2 NO GOVERNMENT APPROVAL. No federal or state agency has passed
upon the Securities, recommended or endorsed the Offering, or made any finding
or determination as to the fairness of this transaction;

            3.3 NO REGISTRATION. The Securities and any component thereof have
not been registered under the Act or any applicable state securities laws by
reason of exemptions from the registration requirements of the Act and such
laws, and may not be sold, pledged (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)
assigned or otherwise disposed of in the absence of an effective registration of
the Securities and any component thereof under the Act or unless an exemption

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.

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.

January 6th, 2000, by and among Techniclone Corporation. a corporation duly
incorporated and existing under the laws of the State of Delaware ("Company"),
and the Subscribers (hereinafter referred to as "Subscribers") to the Company's
Offering ("Offering") of up to Six Hundred Thousand Dollars ($600,000) of Units,
with an Option to purchase an additional Three Hundred Thousand Dollars of Units
as stated in the Subscription Agreement, (the "Units"), each Unit consisting of
one share of Common Stock (the "Unit Shares") and a Warrant ("Unit Warrant") to
purchase one share of Common Stock, all pursuant to the Regulation D
Subscription Agreement between the Company and the Subscribers ("Subscription
Agreement").

                  1. DEFINITIONS. For purposes of this Agreement:

                  (a) The terms "register," "registered," and "registration"
refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with the Securities Act of 1933 (the
"Act"), and pursuant to Rule 415 under the Act or any successor rule, and the
declaration or ordering of effectiveness of such registration statement or
document;

                  (b) For purposes hereof, the term "Registrable Securities"
means the shares of the Company's Common Stock together with any capital stock
issued in replacement of, in exchange for or otherwise in respect of such Common
Stock, issuable or issued (i) as Unit Shares, and (ii) upon exercise of the Unit
Warrants.

                  Notwithstanding the above:

                  1. Common Stock which would otherwise be deemed to be
                  Registrable Securities shall not constitute Registrable
                  Securities if and to the extent that those shares of Common
                  Stock may be resold in a public transaction pursuant to Rule
                  144(k) under the Act; and

                  2. any Registrable Securities resold in a public transaction
                  shall cease to constitute Registrable Securities.

                  (c) [Intentionally Left Blank].

                  (d) The term "Holder" means any person owning or having the
right to acquire Registrable Securities;

                                       1
<PAGE>

                  (e) The term "Filing Date" means the date which is sixty (60)
days after the Closing Date (as defined in the Subscription Agreement) and the
term "Due Date" means either (i) the date which is one hundred fifty (150) days
after such Closing Date, if the Registration Statement is not filed by the
Filing Date, or (ii) the date which is one hundred twenty (120) days after such
Closing Date, if the Registration Statement is filed by the Filing Date, or.

                  2. REQUIRED REGISTRATION.

                  (a) The Company shall use its best efforts to file, by the
Filing Date, a registration statement ("Registration Statement") on Form S-3 (or
other suitable form, at the Company's discretion, but subject to the reasonable
approval of the Holders), covering no more than 7,200,000 shares for holders of
piggyback rights at the time of this Agreement, plus covering the resale of all
of the Registrable Securities, which Registration Statement, to the extent
allowable under the Securities Act and the Rules promulgated thereunder
(including Rule 416), shall state that such Registration Statement also covers
such indeterminate number of additional shares of Common Stock as may become
issuable upon the exercise of the Warrants to prevent dilution resulting from
stock splits, stock dividends or similar transactions. The Company shall use its
best efforts to have the Registration Statement declared effective as soon as
possible. In the event that the Company is notified by a Holder of Registrable
Securities relating to the Units that the Registration Statement does not cover
a sufficient number of shares of Common Stock to effect the resales of a number
of shares of Common Stock equal to at least (i) one hundred fifty percent (150%)
of the number of shares of Common Stock that would be issuable to such Holder (a
"Registration Shortfall"), the Company shall, within seven (7) business days,
amend the Registration Statement or file a new Registration Statement (an
"Amended" or "New" Registration Statement, respectively), as appropriate, to add
such number of additional shares as would be necessary to effect the resales of
a number of shares of Common Stock equal to at least two hundred percent (200%)
of the number of shares of Common Stock that would be issuable to such Holder.
If for any reason or for no reason, the Registration Statement is not declared
effective under the Securities Act on or prior to the Due Date or is not
available for resales of all Registrable Securities at anytime thereafter
("Registration Failure Period"), the Company shall make payments to each Holder
("Registration Failure Payments") which shall accrue at the rate of 2% per
month, accruing daily, on the principal amount of $600,000, or the actual amount
invested, until the later of (a) the end of such Registration Failure Period ,
payable, at the option of the Holder (i) in shares of Common Stock ("Additional
Shares"), valued at the closing bid price of the Common Stock on the business
day immediately prior to the delivery of the Additional Shares or (ii) in cash,
in each case payable within 5 business days of the last day of the calendar
month in which they accrue


         Notwithstanding the above, no Registration Failure Payments shall
accrue prior to the Due Date.

         Such Additional Shares shall also be deemed "Registrable Securities" as
defined herein. The Company covenants to use its best efforts to use Form S-3
for the registration required by this Section during all applicable times
contemplated by this Agreement.

                                       2
<PAGE>

                  (b) The Registration Statement shall be prepared as a "shelf"
registration statement under Rule 415, and shall be maintained effective until
all Registrable Securities cease to exist.

                  (c) The Company represents that it is presently eligible to
effect the registration contemplated hereby on Form S-3 and will use its best
efforts to continue to take such actions as are necessary to maintain such
eligibility.

                  (d) Notwithstanding anything contained herein to the contrary,
the Company shall not be required to register additional shares hereunder if
such shares are not available for issuance as a result of the unavailability of
authorized but unreserved shares of Common Stock.

                  (e) [Intentionally Left Blank].

                  3. PIGGYBACK REGISTRATION. If the Registration Statement
described in Section 2 is not effective and if (but without any obligation to do
so) the Company proposes to register (including for this purpose a registration
effected by the Company for shareholders other than the Holders) any of its
Common Stock under the Act in connection with the public offering of such
securities solely for cash (other than a registration relating solely for the
sale of securities to participants in a Company stock plan or a registration on
Form S-4 promulgated under the Act or any successor or similar form registering
stock issuable upon a reclassification, upon a business combination involving an
exchange of securities or upon an exchange offer for securities of the issuer or
another entity), the Company shall, at such time, promptly give each Holder
written notice of such registration (a "Piggyback Registration Statement"). Upon
the written request of each Holder given by fax within ten (10) days after
mailing of such notice by the Company, the Company shall cause to be included in
such registration statement under the Act all of the Registrable Securities that
each such Holder has requested to be registered ("Piggyback Registration") to
the extent such inclusion does not violate the registration rights of any other
security holder of the Company granted prior to the date hereof; nothing herein
shall prevent the Company from withdrawing or abandoning the registration
statement prior to its effectiveness. The election of initiating Holders to
participate in a Piggyback Registration Statement shall not impact the amount
payable to investors pursuant to Section 2(a) herein except that the
Registration Failure Payment shall cease to accrue as of the date of
effectiveness of the Piggyback Registration Statement.

                  4. LIMITATION ON OBLIGATIONS TO REGISTER.

                  (a) In the case of a Piggyback Registration involving an
underwritten public offering by the Company, if the managing underwriter
determines and advises in writing that the inclusion in the registration
statement of all Registrable Securities proposed to be included would interfere
with the successful marketing of the securities proposed to be registered by the
Company, then the number of such Registrable Securities to be included in the
registration statement, to the extent such Registrable Securities may be
included in such Piggyback Registration Statement, shall be allocated among all
Holders who had requested Piggyback Registration pursuant to the terms hereof,

                                       3
<PAGE>

in the proportion that the number of Registrable Securities which each such
Holder seeks to register bears to the total number of Registrable Securities
sought to be included by all Holders. If required by the managing underwriter of
such an underwritten public offering, the Holders shall enter into a reasonable
agreement limiting the number of Registrable Securities to be included in such
Piggyback Registration Statement and the terms, if any, regarding the future
sale of such Registrable Securities.

                  (b) In the event the Company believes that shares sought to be
registered under Section 2 or Section 3 by Holders do not constitute
"Registrable Securities" by virtue of Section 1(b) of this Agreement, and the
status of those shares as Registrable Securities is disputed, the Company shall
provide, at its expense, an Opinion of Counsel, reasonably acceptable to the
Holders of the Securities at issue (and satisfactory to the Company's transfer
agent to permit the sale and transfer) that those securities may be sold
immediately, without volume limitation without registration under the Act, by
virtue of Rule 144 or similar provisions.

                  5. OBLIGATIONS OF THE COMPANY. Whenever required under this
Agreement to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                  (a) Prepare and file with the Securities and Exchange
Commission ("SEC") a registration statement with respect to such Registrable
Securities and use its best efforts to cause such registration statement to
become effective and to remain effective for the applicable period.

                  (b) Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Act with respect to the disposition of all securities covered
by such registration statement.

                  (c) Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                  (d) Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders of the Registrable Securities covered by such registration statement,
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

                  (e) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                                       4
<PAGE>

                  (f) As promptly as practicable after becoming aware of such
event, notify each Holder of Registrable Securities of the happening of any
event of which the Company has knowledge, as a result of which the prospectus
included in the registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, and promptly prepare
and file a supplement or amendment to the registration statement to correct such
untrue statement or omission, and deliver a number of copies of such supplement
or amendment to each Holder as such Holder may reasonably request.

                  (g) Provide Holders with written notice within one (1)
business day of the date that a registration statement and any amendment thereto
registering the resale of the Registrable Securities is declared effective by
the SEC, and the date or dates when the Registration Statement is no longer
effective.

                  (h) Provide Holders and their representatives the opportunity
to conduct a reasonable due diligence inquiry of Company's pertinent financial
and other records and make available its officers, directors and employees for
questions regarding such information as it relates to information contained in
the registration statement.

                  (i) Provide Holders and their representatives the opportunity
to review the registration statement and all amendments thereto a reasonable
period of time prior to their filing with the SEC if so requested by Holder in
writing.

                  (j) Provide each Holder with prompt notice of the issuance by
the SEC or any state securities commission or agency of any stop order
suspending the effectiveness of the registration statement or the initiation of
any proceeding for such purpose. The Company shall use its best efforts to
prevent the issuance of any stop order, and, if any is issued, to obtain the
removal thereof at the earliest possible dates.

                  (k) Use its best efforts to list the Registrable Securities
covered by the registration statement with all securities exchanges or markets
on which the Common Stock is then listed and prepare and file any required
filing with the NASD or any such exchange or market.

                  6. BLACK OUT. In the event that, during the time that the
Registration Statement is effective, the Company reasonably determines, based
upon advice of counsel, that due to the existence of material non-public
information, disclosure of such material non-public information would be
required to make the statements contained in the Registration Statement not
misleading, and the Company has a bona fide business purpose for preserving as
confidential such material non-public information, the Company shall have the
right to suspend the use of the Registration Statement (a "Registration Black
Out"), and no Holder shall be permitted to sell any Registrable Securities
pursuant thereto, until such time as such suspension is no longer required
hereunder; provided, however, that such time shall not exceed a period of sixty
(60) days. As soon as such suspension is no longer required hereunder, the
Company shall, if required, promptly, but in no event later than the date the
Company files any documents with the Securities and Exchange Commission ("SEC")
referencing such material information, file with the SEC an amendment to the
Registration Statement disclosing such information and use its best efforts to
have such amendment declared effective as soon as possible.

                                       5
<PAGE>

                     In the event that the use of the Registration Statement is
suspended by the Company, the Company shall promptly notify all Holders whose
securities are covered by the Registration Statement of such suspension, and
shall promptly notify each such Holder as soon as use of the Registration
Statement may be resumed. Notwithstanding anything to the contrary, the Company
shall cause the Transfer Agent to deliver unlegended shares of Common Stock to a
transferee of a Holder in accordance with the terms of the Subscription
Agreement in connection with any sale of Registrable Securities with respect to
which such Holder has entered into a contract for sale prior to receipt of
notice of such Registration Black Out and for which such Holder has not yet
settled. The Company shall be entitled to effect no more than one Registration
Black Out during any twelve- (12) month period.

                  7. FURNISH INFORMATION. It shall be a condition precedent to
the obligations of the Company to take any action pursuant to this Agreement
with regard to each selling Holder that such selling Holder shall timely furnish
to the Company such information regarding Holder, the Registrable Securities
held by it, and the intended method of disposition of such securities as shall
be required to effect the registration of its Registrable Securities or to
determine that registration is not required pursuant to Rule 144 or other
applicable provision of the Act.

                  8. EXPENSES. All expenses other than underwriting discounts
and commissions and fees and expenses of counsel to the selling Holders incurred
in connection with registrations, filings or qualifications pursuant hereto,
including (without limitation) all registration, filing and qualification fees,
printers' and accounting fees, fees and disbursements of counsel for the
Company, shall be borne by the Company.

                  9. INDEMNIFICATION. In the event any Registrable Securities
are included in a Registration Statement or a Piggyback Registration Statement
under this Agreement:

                  (a) To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, the officers, directors and agents of each
Holder, any underwriter (as defined in the Act) for such Holder and each person,
if any, who controls such Holder or underwriter within the meaning of the Act or
the Securities Exchange Act of 1934, as amended (the "1934 Act"), against any
losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Act, the 1934 Act or other federal or state law,
insofar as such losses, claims, damages, or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements or
omissions: (i) any untrue statement or alleged untrue statement of a material
fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, or (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, and the Company will reimburse each such Holder, officer
or director, underwriter or controlling person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the
indemnity agreement contained in this subsection 9(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case

                                       6
<PAGE>

for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon a statement which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by any such Holder, officer, director, underwriter or
controlling person.

                  (b) To the extent permitted by law, each selling Holder,
severally and not jointly, will indemnify and hold harmless the Company, each of
its directors, each of its officers who have signed the registration statement,
each person, if any, who controls the Company within the meaning of the Act, any
underwriter and any other Holder selling securities in such registration
statement or any of its directors or officers or any person who controls such
Holder, against any losses, claims, damages, or liabilities (joint or several)
to which the Company or any such director, officer, controlling person, or
underwriter or controlling person, or other such Holder or director, officer or
controlling person may become subject, under the Act, the 1934 Act or other
federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereto) arise out of or are based upon any statement or
omission in each case to the extent (and only to the extent) that such statement
or omission is made in reliance upon and in conformity with written information
furnished by such Holder expressly for use in connection with such registration
statement; and each such Holder will reimburse any legal or other expenses
reasonably incurred by the Company and any such director, officer, controlling
person, underwriter or controlling person, other Holder, officer, director, or
controlling person in connection with investigating or defending any such loss,
claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this subsection 9(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Holder, which consent shall
not be unreasonably withheld.

                  (c) Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 9, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonably incurred fees and
expenses of one such counsel to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential conflicting
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
9, but the omission so to deliver written notice to the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 9.

                                       7
<PAGE>

                  (d) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 9 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and each Holder agree to
contribute to the aggregate claims, losses, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Holder may be subject in such proportion as is appropriate to reflect the
relative fault of the Company and the Holders in connection with the statements
or omissions which resulted in such Losses. Relative fault shall be determined
by reference to whether any alleged untrue statement or omission relates to
information provided by the Company or by the Holders. The Company and the
Holders agree that it would not be just and equitable if contribution were
determined by pro rata allocation or any other method of allocation which does
not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 10(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section 9,
each person who controls a Holder of Registrable Securities within the meaning
of either the Securities Act or the Exchange Act and each director, officer,
partner, employee and agent of a Holder shall have the same rights to
contribution as such holder, and each person who controls the Company within the
meaning of either the Act or the Exchange Act and each director of the Company,
and each officer of the Company who has signed the registration statement, shall
have the same rights to contribution as the Company, subject in each case to the
applicable terms and conditions of this paragraph (d).

                  (e) The obligations of the Company and Holders under this
Section 9 shall survive the completion of any offering of Registrable Securities
in a Registration Statement under this Agreement, and otherwise.

                  10. REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934. With a view
to making available to the Holders the benefits of Rule 144 promulgated under
the Act and any other rule or regulation of the SEC that may at any time permit
a Holder to sell securities of the Company to the public without registration,
the Company agrees to:

                  (a) make and keep public information available, as those terms
are understood and defined in Rule 144;

                  (b) use its best efforts to file with the SEC in a timely
manner all reports and other documents required of the Company under the Act and
the 1934 Act; and

                  11. AMENDMENT OF REGISTRATION RIGHTS. Any provision of this
Agreement may be amended and the observance thereof may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and the Holders of
a majority of the Registrable Securities provided that the amendment treats all
Holders equally. Any amendment or waiver effected in accordance with this
paragraph shall be binding upon each Holder, each future Holder, and the
Company.

                  12. NOTICES. All notices required or permitted under this
Agreement shall be made in writing signed by the party making the same, shall
specify the section under this Agreement pursuant to which it is given, and
shall be addressed if to (i) the Company at the address, telephone number and
facsimile number set forth on the signature pages of this Agreement and (ii) the
Holders at their respective last address and facsimile number of the party as
shown on the records of the Company. Any notice, except as otherwise provided in
this Agreement, shall be made by fax and shall be deemed given at the time of
transmission of the fax.

                                       8
<PAGE>

                  13. TERMINATION. This Agreement shall terminate on the date
all Registrable Securities cease to exist; but without prejudice to (i) the
parties' rights and obligations arising from breaches of this Agreement
occurring prior to such termination (ii) other indemnification obligations under
this Agreement.

                  14. ASSIGNMENT. The rights of a Holder may be transferred to a
subsequent holder of the Holder's Registrable Securities (provided such
transferee shall provide to the Company, together with or prior to such
transferee's request to have such Registrable Securities included in a Piggyback
Registration, a writing executed by such transferee agreeing to be bound as a
Holder by the terms of this Agreement), and the Company hereby agrees to file a
new registration statement or an amended registration statement including such
transferee or a selling security holder thereunder.

                  15. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware applicable to
agreements made in and wholly to be performed in that jurisdiction, except for
matters arising under the Act or the Securities Exchange Act of 1934, which
matters shall be construed and interpreted in accordance with such laws.

                  16. EXECUTION IN COUNTERPARTS PERMITTED. This Agreement may be
executed in any number of counterparts, each of which shall be enforceable
against the parties actually executing such counterparts, and all of which
together shall constitute one (1) instrument.

                  17. SPECIFIC PERFORMANCE. The Holder shall be entitled to the
remedy of specific performance in the event of the Company's breach of this
Agreement, the parties agreeing that a remedy at law would be inadequate.

                  18. ENTIRE AGREEMENT. This Agreement, including the Exhibits
attached hereto, the Subscription Agreement, , the Irrevocable Instructions to
Transfer Agent, and the other documents delivered pursuant hereto constitute the
full and entire understanding and agreement between the parties with regard to
the subjects hereof and thereof.

                                       9

         IN WITNESS WHEREOF, the undersigned have executed this Agreement as of
this 6th day of January, 2000.

                                       OF
                             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

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

         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.

by facsimile.

            (c) CANCELLATION OF WARRANT. This Warrant shall be canceled upon the

         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.

         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,
and upon surrender and cancellation of this Warrant, if mutilated, the Company
shall execute and deliver a new Warrant of like tenor and date.

         12. NOTICE OR DEMANDS.

             Notices or demands pursuant to this Warrant to be given or made by
Holder to or on the Company shall be sufficiently given or made if sent by

                        WARRANT TO PURCHASE COMMON STOCK
                                       OF
                             TECHNICLONE CORPORATION

         THIS CERTIFIES that SWARTZ PRIVATE EQUITY, LLC or any subsequent holder
hereof pursuant to Section 8 hereof ("Holder"), has the right to purchase from
TECHNICLONE CORPORATION, a Delaware corporation (the "Company"), up to 750,000
fully paid and nonassessable shares of the Company's common stock, $.01 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 the date that is five (5) years after the Date of Issuance
(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 AND TERM.

         This Warrant shall be deemed to be issued on November 19, 1999 ("Date
of Issuance"). The term of this Warrant is five (5) years from the Date of
Issuance.

         2. EXERCISE.

            (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 (the "Warrant Shares") 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, 14282 Franklin Avenue, Tustin, CA, 92780, Attention: John N.

<PAGE>

Bonfiglio, Interim President, Telephone No. (714) 508-6000, Telecopy No. (714)
838-4094, 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 per share ("Exercise Price") shall initially equal
$0.46875 (the "Initial Exercise Price"). If the average Closing Bid Price of the
Company's Common Stock for the five (5) trading days immediately preceding the
date, if any, that the Company and Swartz Private Equity, LLC enter into an
Investment Agreement ("Investment Agreement") pursuant to the Letter of
Agreement between the Company and Swartz Private Equity, LLC dated on or about
November 5, 1999 (the "Closing Market Price") is less than the Initial Exercise
Price, the Exercise Price shall be reset to equal the Closing Market Price, or,
if the Date of Exercise is more than six (6) months after the Date of Issuance,
the Exercise Price shall be reset to equal the lesser of (i) the Exercise Price
then in effect, or (ii) the "Lowest Reset Price," as that term is defined below.
The Company shall calculate a "Reset Price" on each six-month anniversary date
of the Date of Issuance which shall equal one hundred percent (100%) of the
average Closing Bid Price of the Company's Common Stock for the five (5) trading
days ending on such six-month anniversary date of the Date of Issuance. The
"Lowest Reset Price" shall equal the lowest Reset Price determined on any
six-month anniversary date of the Date of Issuance preceding the Date of
Exercise, taking into account, as appropriate, any adjustments made pursuant to
Section 5 hereof.

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

                                       2
<PAGE>

            (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:

                                  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 Bid 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
                  O.T.C. Bulletin Board, 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 hereof, the term "Closing Bid Price" shall mean the
closing bid price of the Company's common stock on the O.T.C. Bulletin Board,
the National Market System ("NMS"), the New York Stock Exchange, the Nasdaq
Small Cap Market, or if no longer traded on the O.T.C. Bulletin Board, the NMS,
the New York Stock Exchange, the Nasdaq Small Cap Market, the "Closing Bid
Price" shall equal the closing price on the principal national securities
exchange or the over-the-counter system on which the Common Stock is so traded
and, if not available, the mean of the high and low prices on the principal
national securities exchange on which the Common Stock is so traded.

         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. In addition to any other registration
rights of the Holder, if the Common Stock issuable upon exercise of this Warrant
is not registered for resale at the time the Company proposes to register
(including for this purpose a registration effected by the Company for
stockholders other than the Holders) any of its Common Stock under the Act
(other than a registration relating solely for the sale of securities to
participants in a Company stock plan or a registration on Form S-4 promulgated
under the Act or any successor or similar form registering stock issuable upon a
reclassification, upon a business combination involving an exchange of
securities or upon an exchange offer for securities of the issuer or another
entity)(a "Piggyback Registration Statement"), the Company shall cause to be
included in such Piggyback Registration Statement ("Piggyback Registration") all
of the Common Stock issuable upon the exercise of this Warrant ("Registrable
Securities") to the extent such inclusion does not violate the registration
rights of any other securityholder of the Company granted prior to the date
hereof. Nothing herein shall prevent the Company from withdrawing or abandoning
the Piggyback Registration Statement prior to its effectiveness.

            (c) LIMITATION ON OBLIGATIONS TO REGISTER UNDER A PIGGYBACK
REGISTRATION. In the case of a Piggyback Registration pursuant to an
underwritten public offering by the Company, if the managing underwriter
determines and advises in writing that the inclusion in the registration
statement of all Registrable Securities proposed to be included would interfere
with the successful marketing of the securities proposed to be registered by the
Company, then the number of such Registrable Securities to be included in the
Piggyback Registration Statement, to the extent such Registrable Securities may
be included in such Piggyback Registration Statement, shall be allocated among
all Holders who had requested Piggyback Registration pursuant to the terms
hereof, in the proportion that the number of Registrable Securities which each
such Holder seeks to register bears to the total number of Registrable
Securities sought to be included by all Holders. If required by the managing
underwriter of such an underwritten public offering, the Holders shall enter
into a reasonable agreement limiting the number of Registrable Securities to be
included in such Piggyback Registration Statement and the terms, if any,
regarding the future sale of such Registrable Securities.

         5. ANTI-DILUTION ADJUSTMENTS.

            (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.

                                       4
<PAGE>

            (b) RECAPITALIZATION OR RECLASSIFICATION.

                  (i) STOCK SPLIT. 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 number of shares (a "Stock Split"), 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 in
direct proportion to the increase in the number of shares of Common Stock by
reason of such recapitalization, reclassification or similar transaction, and
the Exercise Price shall be proportionally decreased.

                  (ii) REVERSE STOCK SPLIT. 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 SMALLER number of shares (a "Reverse Stock Split"), 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 decreased
by reason of such recapitalization, reclassification or similar transaction,
provided, however that the Exercise Price shall be 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 years) 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.

                                       5
<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.

            (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.

         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 unless the Company has received an opinion from the
Company's counsel to the effect that such registration is not required, or the
Holder has furnished to the Company an opinion of the Holder's counsel, which
counsel shall be reasonably satisfactory to the Company, to the effect that such
registration is not required; the transfer complies with any applicable state
securities laws; and, if no registration covering the resale of the Warrant
Shares is effective at the time the Warrant Shares are issued, the Holder
consents to a legend being placed on certificates for the Warrant Shares stating
that the securities have not been registered under the Securities Act and
referring to such restrictions on transferability and sale.

            (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.

                                       6
<PAGE>

         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.

         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,
and upon surrender and cancellation of this Warrant, if mutilated, the Company
shall execute and deliver a new Warrant of like tenor and date.

         12. NOTICE OR DEMANDS.

             Notices or demands pursuant to this Warrant to be given or made by
Holder to or on the Company shall be sufficiently given or made if sent by
certified or registered mail, return receipt requested, postage prepaid, and
