                             TECHNICLONE CORPORATION

     Techniclone Corporation was incorporated in the State of Delaware on
September 25, 1996. On March 24, 1997, Techniclone International Corporation, a
California corporation (a predecessor company incorporated in June 1981), was
merged with and into Techniclone. This merger was effected for the purpose of
effecting a change in our state of incorporation from California to Delaware and
making certain changes in our charter documents. Techniclone has one
wholly-owned subsidiary Peregrine Pharmaceuticals, Inc., a Delaware corporation.

     Techniclone is a biopharmaceutical company engaged in the research,
development and commercialization of targeted cancer therapeutics. We develop
product candidates based primarily on our proprietary collateral tumor targeting
technologies for the treatment of solid tumors and a direct tumor targeting
agent for the treatment of refractory malignant lymphoma.

     Collateral tumor targeting is the therapeutic strategy of targeting
peripheral structures and cell types, other than the viable cancer cells
directly, as a means to treat solid tumors. We are currently developing three
advanced collateral targeting agents for solid tumors: tumor necrosis therapy,
which is potentially capable of carrying a variety of therapeutic agents to the
interior of solid tumors and irradiating the tumor from the inside out;
vaseopermeation enhancement agents, which increase the permeability of the tumor
site and increase the concentration of killing agents at the core of the tumor;
and vascular targeting agents, which shut down the capillaries and blood vessels
that serve solid tumors and destroy the vascular structure of the tumor.
Clinical trials of our tumor necrosis therapy agent for the treatment of brain
cancer are currently being conducted at one medical center, with additional
sites underway, and an additional clinical trial for the treatment of
pancreatic, prostrate and liver cancers has been initiated at a clinical site in
Mexico City. Our scientists are doing preliminary studies on vaseopermeation
enhancement agents and on vascular targeting agents. Our direct tumor targeting
agent candidate, Oncolym(R), is currently being studied in advanced clinical
trials for the treatment of intermediate and high-grade relapsed or refractory
B-cell non-Hodgkins lymphoma at nine participating medical centers.

     To date, we have not received any significant revenues. However, on March
8, 1999 we entered into a license agreement with Schering A.G., Germany, a major
international pharmaceutical company, with respect to the development,
manufacture and marketing of our most advanced direct tumor targeting agent
candidate, Oncolym(R), and received an initial $3 million payment. The license
agreement with Schering A.G., Germany also provides for additional payments and
reimbursements of up to $17 million, subject to the achievement of certain
milestones, and royalties based on sales of Oncolym(R). In connection with our
agreement with Schering A.G., Germany for Oncolym(R), Schering A.G., Germany has
agreed to discuss with us the development and commercialization of vascular
targeting agents, one of our collateral tumor targeting technologies.

     Our principal executive offices are located at 14282 Franklin Avenue,
Tustin, California 92780-7017 and our telephone number is (714) 508-6000.

                                  RISK FACTORS

     INVESTMENT IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD
CONSIDER THE FOLLOWING DISCUSSION OF RISKS AS WELL AS OTHER INFORMATION IN THIS
PROSPECTUS BEFORE PURCHASING ANY OF OUR COMMON STOCK, TOGETHER WITH ALL OF THE
OTHER INFORMATION CONTAINED IN THIS PROSPECTUS OR INCORPORATED IN THIS
PROSPECTUS BY REFERENCE.

IF WE CANNOT OBTAIN ADDITIONAL FUNDING, OUR PRODUCT DEVELOPMENT AND
 COMMERCIALIZATION EFFORTS MAY BE REDUCED OR DISCONTINUED

     We have expended, and will continue to expend, substantial funds on the
development of our product candidates and for clinical trials. As a result, we
have had negative cash flows from operations since inception and expect the
negative cash flow from operations to continue for the foreseeable future. We
currently have commitments to expend additional funds for antibody and
radioactive isotope combination services, clinical trials, product development
contracts, license contracts, severance arrangements, employment agreements,
consulting agreements, and for the repurchase of marketing rights to certain
product technology. We expect operating expenditures related to clinical trials
to increase in the future as clinical trial activity increases and expansion for
clinical trial production continues. We also expect that the monthly negative
cash flow will continue. We will require additional funding to sustain our
research and development efforts, provide for future clinical trials, expand our
manufacturing and product commercialization capabilities, and continue our
operations until we are able to generate sufficient revenue from the sale and/or
licensing of our products. Our ability to access funds under our Regulation D
Common Stock Equity Line Subscription Agreement with two institutional investors
is subject to the satisfaction of certain conditions. The failure to satisfy
these conditions may limit or preclude our ability to access such funds, which
could negatively affect our financial position unless additional financing
sources are available. We cannot be certain whether we can obtain required
additional funding on terms satisfactory to us, if at all. If we do raise
additional funds through the issuance of equity or convertible debt securities,
your stock ownership will be diluted and these new securities may have rights,
preferences or privileges senior to yours. If we are unable to raise additional
funds when necessary, we may have to reduce or discontinue development,
commercialization or clinical testing of some or all of our product candidates
or enter into financing arrangements on terms which we would not otherwise
accept.

WE HAVE HAD SIGNIFICANT LOSSES AND ANTICIPATE FUTURE LOSSES

     We have experienced significant losses since inception. As of January 31,
1999, our accumulated deficit was approximately $84,429,000. We expect to incur
significant additional operating losses in the future and expect cumulative
losses to increase substantially due to expanded research and development
efforts, preclinical studies and clinical trials, and expansion of manufacturing
and product commercialization capabilities. We also expect losses to fluctuate
substantially from quarter to quarter. All of our products are currently in
development, preclinical studies or clinical trials, and no significant revenues
have been generated from product sales. To achieve and sustain profitable
operations, we must successfully develop and obtain regulatory approval for our
products, either alone or with others, and must also manufacture, introduce,
market and sell our products. The time frame necessary to achieve market success
for our products is long and uncertain. We do not expect to generate significant
product revenues for the next year. There can be no guarantee that we will ever
generate product revenues sufficient to become profitable or to sustain
profitability.

PROBLEMS IN PRODUCT DEVELOPMENT MAY CAUSE OUR CASH DEPLETION RATE TO INCREASE

     Our ability to obtain financing and to manage expenses and our cash
depletion rate is key to the continued development of product candidates and the
completion of ongoing clinical trials. Our cash depletion rate will vary


                                       4
<PAGE>


substantially from quarter to quarter as we fund non-recurring items associated
with clinical trials, product development, antibody manufacturing and facility
expansion and scale-up, patent legal fees and various consulting fees. We have
limited experience with clinical trials and if we encounter unexpected
difficulties with our operations or clinical trials, we may have to expend
additional funds, which would increase our cash depletion rate.

OUR PRODUCT DEVELOPMENT AND COMMERCIALIZATION EFFORTS MAY NOT BE SUCCESSFUL

     Since inception, we have been engaged in the development of drugs and
related therapies for the treatment of people with cancer. Our product
candidates, which have not received regulatory approval, are generally in the
early stages of development. If the initial results from any of the clinical
trials are poor, those results will adversely effect our ability to raise
additional capital, which will affect our ability to continue full-scale
research and development for our antibody technologies. In addition, product
candidates resulting from our research and development efforts, if any, are not
expected to be available commercially for at least the next year. Our products
currently in clinical trials represent a departure from more commonly used
methods for cancer treatment. These products, if approved, may experience
under-utilization by doctors who are unfamiliar with their application in the
treatment of cancer. As with any new drug, doctors may be inclined to continue
to treat patients with conventional therapies, in most cases chemotherapy,
rather than new alternative therapies. We or our marketing partner may be
required to implement an aggressive education and promotion plan with doctors in
order to gain market recognition, understanding and acceptance of our products.
Market acceptance could also be affected by the availability of third-party
reimbursement. Accordingly, we cannot guarantee that our product development
efforts, including clinical trials, or commercialization efforts will be
successful or that any of our products, if approved, can be successfully
marketed.

WE MAY NOT BE ABLE TO EXPAND OUR FACILITIES TO IMPLEMENT COMMERCIAL PRODUCTION
 OF OUR PRODUCTS

     In order to conduct clinical trials on a timely basis, obtain regulatory
approval and be commercially successful, we must expand our manufacturing and
product commercialization processes so that our product candidates, if approved,
can be manufactured and produced in commercial quantities. To date, we have
expended significant funds for the expansion of our antibody manufacturing
capabilities for clinical trial requirements for two of our product candidates
and for refinement of the production processes. We intend to use existing
antibody manufacturing capacity to meet the clinical trial requirements for
these two product candidates and to support the initial commercialization of
these product candidates, if approved. In order to provide additional capacity,
we must successfully negotiate agreements with contract antibody manufacturers
to have these products produced, the cost of which is estimated to be several
million dollars in start-up costs and additional production costs on a "per run
basis". Such contracts would also require an additional investment estimated at
five to nine million dollars over the next two years for required equipment and
related production area enhancements, and for vendor services associated with
technology transfer assistance, expansion and production start-up and for
regulatory assistance. We have limited manufacturing experience, and cannot make
any guarantee as to our ability to expand our manufacturing operations, the
suitability of our present facility for clinical trial production or commercial
production, our ability to make a successful transition to commercial production
or our ability to reach an acceptable agreement with one or more contract
manufacturers to produce any of our other product candidates, if approved, in
clinical or commercial quantities.

OUR TECHNOLOGY AND PRODUCTS MAY PROVE INEFFECTIVE OR BE TOO EXPENSIVE TO MARKET
 SUCCESSFULLY

     Our future success is significantly dependent on our ability to develop and
test workable products for which we will seek approval from the United States
Food and Drug Administration to market to certain defined patient groups. There
is a significant risk as to the performance and commercial success of our
technology and products. The products we are currently developing will require
significant additional laboratory and clinical testing and investment over the
foreseeable future. Our proposed products may not prove to be effective in
clinical trials or they may cause harmful side effects during clinical trials.
In addition, our product candidates, if approved, may prove impracticable to
manufacture in commercial quantities at a reasonable cost and/or with acceptable
quality. Any of these factors could negatively affect our financial position and
results of operations.

OUR DEPENDENCY ON A LIMITED NUMBER OF SUPPLIERS MAY NEGATIVELY IMPACT OUR
 ABILITY TO COMPLETE CLINICAL TRIALS AND MARKET OUR PRODUCTS

     We currently procure, and intend in the future to procure, our antibody and
radioactive isotope combination services under negotiated contracts with two
domestic entities, one Canadian entity and one European entity. We cannot
guarantee that these suppliers will be able to qualify their facilities or label
and supply antibody in a timely manner, if at all. Prior to commercial
distribution of any of our products, if approved, we will be required to
identify and contract with a commercial company for commercial antibody and
radioactive isotope combination services. We are presently in discussions with a
few companies to provide commercial antibody and radioactive isotope combination
services. We also currently rely on, and expect in the future to rely on, our
current suppliers for all or a significant portion of our requirements for our
antibody products. Antibody that has been combined with a radioactive isotope
cannot be stockpiled against future shortages. Accordingly, any change in our
existing or future contractual relationships with, or an interruption in supply
from, any such third-party service provider or antibody supplier could
negatively impact our ability to complete ongoing clinical trials and to market
our products, if approved.

TERMINATION OF OUR RELATIONSHIP WITH SCHERING A.G., GERMANY COULD ADVERSELY
 AFFECT OUR BUSINESS

     In March 1999, we entered into a worldwide license agreement with Schering
A.G., Germany for the worldwide development, marketing and distribution of our
advanced direct tumor targeting agent product candidate, Oncolym(R). Under the
agreement, Schering A.G., Germany has assumed control of the development of this
product candidate and is responsible for obtaining regulatory approvals in the
United States and all foreign countries and handling sales and marketing of this
product candidate. Schering A.G., Germany may terminate the agreement under
certain circumstances, including if (i) there are issues of safety or patient
tolerability, (ii) Schering A.G., Germany determines in its reasonable
scientific or business discretion prior to receiving regulatory approval that
this product candidate is not acceptable for reasons of efficacy or risk/benefit
therapeutic ratio, (iii) the United States Food and Drug Administration does not
permit the extension or conversion of the current clinical trials by June 30,
1999, or (iv) at any time after receiving regulatory approval upon twelve months
notice to us. Schering A.G., Germany may also terminate the agreement upon
thirty days' written notice given at any time prior to receiving regulatory
approval. We are relying on Schering A.G., Germany to apply its expertise and
know-how through the development, launch and sale of this product candidate. If
Schering A.G., Germany 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. In
connection with our agreement with Schering A.G., Germany for our advanced
direct tumor targeting agent product candidate, Schering A.G., Germany has also
agreed to discuss the development and commercialization of our vascular


                                       6
<PAGE>


targeting agent technology. If we enter into an agreement with Schering A.G.,
Germany with respect to our vascular targeting agent technology, we will also
rely on Schering A.G., Germany to apply its expertise and know-how through the
development, launch and sale of our vascular targeting agent product candidates.
We cannot guarantee that Schering A.G., Germany will devote the resources
necessary to successfully develop and/or market any product candidate.

WE DO NOT HAVE A SALES FORCE TO MARKET OUR PRODUCTS

     At the present time, we do not have a sales force to market any of our
products, if and when they are approved. We intend to sell our products in the
United States and internationally in collaboration with one or more marketing
partners. If and when we receive approval from the United States Food and Drug
Administration for our initial product candidates, the marketing of these
products will be contingent upon our ability to either license or enter into a
marketing agreement with a large company or our ability to recruit, develop,
train and deploy our own sales force. We do not presently possess the resources
or experience necessary to market any of our product candidates. Other than an
agreement with Schering A.G., Germany with respect to the marketing of our
direct tumor targeting agent product candidate, we presently have no agreements
for the licensing or marketing of our product candidates, and we cannot assure
you that we will be able to enter into any such agreements in a timely manner or
on commercially favorable terms, if at all. Development of an effective sales
force requires significant financial resources, time and expertise. We cannot
assure you that we will be able to obtain the financing necessary to establish
such a sales force in a timely or cost effective manner, if at all, or that such
a sales force will be capable of generating demand for our product candidates,
if and when they are approved.

WE MAINTAIN ONLY LIMITED PRODUCT LIABILITY INSURANCE AND MAY BE EXPOSED TO
 CLAIMS IF OUR INSURANCE COVERAGE IS INSUFFICIENT

     The manufacture and sale of human therapeutic products involves an inherent
risk of product liability claims. We maintain only limited product liability
insurance. We cannot assure you that we will be able to maintain existing
insurance or obtain additional product liability insurance on acceptable terms
or with adequate coverage against potential liabilities. Product liability
insurance is expensive, difficult to obtain and may not be available in the
future on acceptable terms, if at all. Our inability to obtain sufficient
insurance coverage on reasonable terms or to otherwise protect against potential
product liability claims in excess of our insurance coverage, if any, or a
product recall could negatively impact our financial position and results of
operations.

EARTHQUAKES MAY DAMAGE OUR FACILITIES

     Our corporate and research facilities, where the majority of our research
and development activities are conducted, are located near major earthquake
faults which have experienced earthquakes in the past. Although we carry limited
earthquake insurance, in the event of a major earthquake or other disaster in or
near the greater Southern California area, our facilities may sustain
significant damage and our operations could be negatively affected.

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

     The Common Stock 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


                                       7
<PAGE>


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, we have failed to maintain a $1.00 minimum closing bid price for extended
periods of time and expect the closing bid price of the Common Stock to fall
below the $1.00 minimum bid requirement from time to time in the future. As of
April 28, 1999, we have failed to maintain a $1.00 minimum closing bid price for
17 consecutive trading days. If we fail to meet the minimum closing bid price of
$1.00 for a period of 30 consecutive trading days, we will be notified by The
Nasdaq Stock Market and will then have a period of 90 calendar days from such
notification to achieve compliance with the applicable standard by meeting the
minimum closing bid price requirement for at least 10 consecutive trading days
during such 90 day period. We cannot guarantee that we will be able to maintain
these requirements in the future. If we fail to meet any of The Nasdaq SmallCap
Market listing requirements, 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. In addition, if the minimum closing bid price of the Common Stock
is not at least $1.00 per share for 10 consecutive trading days before we make a
call for proceeds under our Regulation D Common Stock Equity Line Subscription
Agreement with two institutional investors or if the Common Stock ceases to be
included on The Nasdaq SmallCap Market, we would have limited or no access to
funds under the Regulation D Common Stock Equity Line Subscription Agreement.
Moreover, should the market price of the Common Stock fall significantly, we
would be required to issue to the two institutional investors a much greater
number of shares than we would otherwise if the market price were stable or
rising, which could cause the market price of the Common Stock to fall further
and faster. In addition, we and broker-dealers effecting transactions in the
Common Stock may become subject to additional disclosure and reporting
requirements applicable to low-priced securities, which may reduce the level of
trading activity in the secondary market for the Common Stock and limit or
prevent investors from readily selling their shares of Common Stock.

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

     As of June 2, 1999, we had approximately 74,536,000 shares of Common Stock
outstanding. We are also obligated to issue up to an additional approximately
254,000 shares of Common Stock upon conversion of outstanding shares of our 5%
Adjustable Convertible Class C Preferred Stock and exercise of related warrants,
and may issue up to an additional approximately 18,666,000 shares of Common
Stock from time to time under our Regulation D Common Stock Equity Line
Subscription Agreement with two institutional investors in exchange for an
aggregate purchase price of $13,575,000. In addition, we are obligated to issue
warrants equal to 10% of the shares of Common Stock issued under such agreement,
wich must be exercised on a cashless basis only, and an additional approximately
15,538,000 shares of Common Stock issuable upon exercise of other outstanding
options and other warrants. The conversion rate applicable to our Class C
Preferred Stock and the purchase price for the shares of Common Stock to be
issued under the Regulation D Common Stock Equity Line Subscription Agreement,
and the exercise price of related warrants, are at a significant discount to the
market price of the Common Stock. 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. See "The Equity Line Agreement."

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, have 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 89,000 shares per
day to as many as 19 million shares per day over the past eighteen months, and


                                       8
<PAGE>


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.

WE MAY NOT BE ABLE TO COMPETE WITH OUR COMPETITORS IN THE BIOTECHNOLOGY INDUSTRY

     The biotechnology industry is intensely competitive. It is also subject to
rapid change and sensitive to new product introductions or enhancements. We
expect to continue to experience significant and increasing levels of
competition in the future. Virtually all of our existing competitors have
greater financial resources, larger technical staffs, and larger research
budgets than we have, as ell as greater experience in developing products and
running clinical trials. Two of our competitors, IDEC Pharmaceuticals
Corporation and Coulter Pharmaceuticals, Inc., each has a lymphoma antibody that
may compete with our direct tumor targeting agent product, Oncolym(R). IDEC
Pharmaceuticals Corporation is currently marketing its lymphoma product for low
grade non-Hodgkins lymphoma and we believe that Coulter Pharmaceuticals, Inc.
will be marketing its respective lymphoma product prior to the time our
Oncolym(R) product will be submitted to the United States Food and Drug
Administration for marketing approval. Coulter Pharmaceuticals, Inc. has also
announced that it intends to seek to conduct clinical trials of its antibody
treatment for intermediate and/or high-grade non-Hodgkins lymphomas. In
addition, there may be other companies which are currently developing
competitive technologies and products or which may in the future develop
technologies and products which are comparable or superior to our technologies
and products. Some or all of these companies may also have greater financial and
technical resources than we have. Accordingly, we cannot assure you that we will
be able to compete successfully with our existing and future competitors or that
competition will not negatively affect our financial position or results of
operations in the future.

WE MAY NOT BE SUCCESSFUL IF WE ARE UNABLE TO OBTAIN AND MAINTAIN PATENTS AND
 LICENSES TO PATENTS

     Our success depends, in large part, on our ability to obtain or maintain a
proprietary position in our products through patents, trade secrets and orphan
drug designations. We have been granted several United States patents and have
submitted several United States patent applications and numerous corresponding
foreign patent applications, and have also obtained licenses to patents or
patent applications owned by other entities. However, we cannot assure you that
any of these patent applications will be granted or that our patent licensors
will not terminate any of our patent licenses. We also cannot guarantee that any
issued patents will provide competitive advantages for our products or that any
issued patents will not be successfully challenged or circumvented by our
competitors. Although we believe that our patents and our licensors' patents do
not infringe on any third party's patents, we cannot be certain that we can
avoid litigation involving such patents or other proprietary rights. Patent and
proprietary rights litigation entails substantial legal and other costs, and we
may not have the necessary financial resources to defend or prosecute our rights
in connection with any litigation. Responding to, defending or bringing claims
related to patents and other intellectual property rights may require our
management to redirect our human and monetary resources to address these claims
and may take years to resolve.

OUR PRODUCT DEVELOPMENT AND COMMERCIALIZATION EFFORTS MAY BE REDUCED OR
 DISCONTINUED DUE TO DIFFICULTIES OR DELAYS IN CLINICAL TRIALS

     We may encounter unanticipated problems, including development,
manufacturing, distribution, financing and marketing difficulties, during the
product development, approval and commercialization process. Our product
candidates may take longer than anticipated to progress through clinical trials
or patient enrollment in the clinical trials may be delayed or prolonged
significantly, thus delaying the clinical trials. Delays in patient enrollment
will result in increased costs and further delays. If we experience any such
difficulties or delays, we may have to reduce or discontinue development,
commercialization or clinical testing of some or all of our product candidates.
Schering A.G., Germany has recently advised us that it is reviewing the clinical
development program for our direct tumor targeting agent product candidate and
has stopped enrolling new patients in ongoing clinical trials for this product
candidate under the current protocol. Schering A.G., Germany has further
informed us that it presently intends to submit a revised protocol to the United
States Food and Drug Administration which will contemplate additional clinical
trials in the current phase. If Schering A.G., Germany decides to discontinue
the development of this product candidate and terminates our license agreement
for the worldwide development, distribution and marketing of this product
candidate, we may have to discontinue development, commercialization and
clinical testing of this product candidate.

OUR PRODUCT DEVELOPMENT AND COMMERCIALIZATION EFFORTS MAY BE REDUCED OR
 DISCONTINUED DUE TO DELAYS OR FAILURE IN OBTAINING REGULATORY APPROVALS

     We will need to do substantial additional development and clinical testing
prior to seeking any regulatory approval for commercialization of our product
candidates. Testing, manufacturing, commercialization, advertising, promotion,
export and marketing, among other things, of our proposed products are subject
to extensive regulation by governmental authorities in the United States and
other countries. The testing and approval process requires substantial time,
effort and financial resources and we cannot guarantee that any approval will be
granted on a timely basis, if at all. Companies in the pharmaceutical and
biotechnology industries have suffered significant setbacks in conducting
advanced human clinical trials, even after obtaining promising results in
earlier trials. Furthermore, the United States Food and Drug Administration may
suspend clinical trials at any time on various grounds, including a finding that
the subjects or patients are being exposed to an unacceptable health risk. Even
if regulatory approval of a product is granted, such approval may entail
limitations on the indicated uses for which it may be marketed. Accordingly, we
may experience difficulties and delays in obtaining necessary governmental
clearances and approvals to market our products, and we may not be able to
obtain all necessary governmental clearances and approvals to market our
products. At least initially, we intend, to the extent possible, to rely on
licensees to obtain regulatory approval for marketing our products. The failure
by us or our licensees to adequately demonstrate the safety and efficacy of any
of our product candidates under development could delay, limit or prevent
regulatory approval of the product, which may require us to reduce or
discontinue development, commercialization or clinical testing of some or all of
our product candidates.

OUR PRODUCTS, IF APPROVED, MAY NOT BE COMMERCIALLY VIABLE DUE TO HEALTH CARE
 REFORM AND THIRD-PARTY REIMBURSEMENT LIMITATIONS

     Recent initiatives to reduce the federal deficit and to reform health care
delivery are increasing cost-containment efforts. We anticipate that Congress,
state legislatures and the private sector will continue to review and assess
alternative benefits, controls on health care spending through limitations on
the growth of private health insurance premiums and Medicare and Medicaid
spending, price controls on pharmaceuticals and other fundamental changes to the
health care delivery system. Legislative debate is expected to continue in the
future, and market forces are expected to drive reductions of health care costs.
Any such changes could negatively impact the commercial viability of our


                                       10
<PAGE>


products, if approved. Our ability to successfully commercialize our product
candidates, if and when they are approved, will depend in part on the extent to
which appropriate reimbursement codes and authorized cost reimbursement levels
of such products and related treatment are obtained from governmental
authorities, private health insurers and other organizations, such as health
maintenance organizations. In the absence of national Medicare coverage
determination, local contractors that administer the Medicare program, within
certain guidelines, can make their own coverage decisions. Accordingly, there
can be no assurance that any of our product candidates, if approved and when
commercially available, will be included within the then current Medicare
coverage determination or the coverage determination of state Medicaid programs,
private insurance companies and other health care providers. In addition,
third-party payors are increasingly challenging the prices charged for medical
products and services. Also, the trend toward managed health care and the growth
of health maintenance organizations in the United States may all result in lower
prices for our products, if approved and when commercially available, than we
currently expect. The cost containment measures that health care payors and
providers are instituting and the effect of any health care reform could
negatively affect our financial performance, if and when one or more of our
products are approved and available for commercial use.

OUR MANUFACTURING AND USE OF HAZARDOUS AND RADIOACTIVE MATERIALS MAY RESULT IN
 OUR LIABILITY FOR DAMAGES, INCREASED COSTS AND INTERRUPTION OF ANTIBODY
  SUPPLIES

     The manufacturing and use of our products require the handling and disposal
of the radioactive isotope I131. We currently rely on, and intend in the future
to rely on, our current contract manufacturers to combine antibodies with
radioactive I131 isotope in our products and to comply with various local, state
and or national and international regulations regarding the handling and use of
radioactive materials. Violation of these local, state, national or
international regulations by these companies or a clinical trial site could
significantly delay completion of the trials. Violations of safety regulations
could occur with these manufacturers, so there is also a risk of accidental
contamination or injury. Accordingly, we could be held liable for any damages
that result from an accident, contamination or injury caused by the handling and
disposal of these materials, as well as for unexpected remedial costs and
penalties that may result from any violation of applicable regulations. In
addition, we may incur substantial costs to comply with environmental
regulations. In the event of any noncompliance or accident, the supply of
antibodies for use in clinical trials or commercial products could also be
interrupted.

OUR OPERATIONS AND FINANCIAL PERFORMANCE COULD BE NEGATIVELY AFFECTED IF WE
 CANNOT ATTRACT AND RETAIN KEY PERSONNEL

     Our success is dependent, in part, upon a limited number of key executive
officers and technical personnel remaining employed with us, including Larry O.
Bymaster, our President and Chief Executive Officer, Steven C. Burke, our Chief
Financial Officer, and Dr. John N. Bonfiglio, our Vice President of Technology
and Business Development and interim Vice President of Clinical and Regulatory
Affairs. We also believe that our future success will depend largely upon our
ability to attract and retain highly-skilled research and development and
technical personnel. We face intense competition in our recruiting activities,
including larger companies with greater resources. We do not know if we will be
successful in attracting or retaining skilled personnel. The loss of certain key
employees or our inability to attract and retain other qualified employees could
negatively affect our operations and financial performance.

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

     We are aware of the issues associated with the programming code in existing
computer systems as the year 2000 approaches. The year 2000 problem is pervasive
and complex. The issue is whether computer systems will properly recognize
date-sensitive information in the year 2000 due to the fact that the programming
in most computer systems use a two digit year value, which value will rollover


                                       11
<PAGE>


to "00" as of January 1, 2000. Systems that do not properly recognize such
information could generate erroneous data or cause a system to fail. We have
identified substantially all of our major hardware and software platforms in use
and have modified and upgraded our hardware, software and information technology
and other systems to be year 2000 compliant. We do not presently believe that
the year 2000 problem will pose significant operational problems for our
internal computer systems or have a negative affect on our operations. However,
we cannot assure you that any year 2000 compliance problems of our suppliers
will not negatively affect our operations. Because uncertainty exists concerning
the potential costs and effects associated with any year 2000 compliance, we
intend to continue to make efforts to ensure that third parties with whom we
have relationships are year 2000 compliant. We have not incurred significant
costs to date associated with year 2000 compliance and presently believe
estimated future costs will not be material. However, actual results could
differ materially from our expectations due to unanticipated technological
difficulties or project delays. If we or any third parties upon which we rely
are unable to address the year 2000 issue in a timely manner, it could have an
adverse impact on our operations. In order to assure that this does not occur,
we have developed a contingency plan and intend to devote all resources required
to attempt to resolve any significant year 2000 problems in a timely manner.

                           FORWARD-LOOKING STATEMENTS

     Except for historical information, the information contained in this
prospectus and in our reports filed with the SEC are "forward looking"
statements about our expected future business and financial performance. These
statements involve known and unknown risks, including, among others, risks
resulting from economic and market conditions, the regulatory environment in
which we operate, pricing pressures, accurately forecasting operating and
capital expenditures and clinical trial costs, competitive activities,
uncertainties of litigation and other business conditions, and are subject to
uncertainties and assumptions contained elsewhere in this prospectus. We base
our forward-looking statements on information currently available to us, and we
assume no obligation to update these statements. Our actual operating results
and financial performance may prove to be very different from what we might have
predicted as of the date of this prospectus due to certain risks and
uncertainties. The risks described above in the section entitled "Risk Factors"
specifically address some of the factors that may affect our future operating
results and financial performance.

                 INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

     The SEC allows us to "incorporate by reference" into this prospectus the
documents we file with them, which means that we can disclose important
information to you by referring you to these documents. The information that we
incorporate by reference into this prospectus is considered to be part of this
prospectus, and information that we file later with the SEC automatically
updates and supersedes any information in this prospectus. We incorporate by
reference into this prospectus the documents listed below:

                            THE EQUITY LINE AGREEMENT

     On June 16, 1998, Techniclone entered into a Regulation D Common Stock
Equity Line Subscription Agreement with two institutional investors. Under this
agreement, Techniclone may issue and sell, from time to time, shares of its
Common Stock for cash consideration up to an aggregate of $20 million.
Techniclone also entered into a Placement Agent Agreement and engaged the
services of Swartz Investments, LLC, a Georgia limited liability company doing
business as Swartz Institutional Finance, as placement agent in connection with
the placement of securities of Techniclone with the two institutional investors
under the Regulation D Common Stock Equity Line Subscription Agreement. Swartz
Investments, LLC subsequently assigned and conveyed all of its rights under the
Placement Agent Agreement and a related Registration Rights Agreement to
Dunwoody Brokerage Services, Inc. and also transferred to Dunwoody Brokerage
Services, Inc. all of the shares of Common Stock and warrants to purchase shares
of Common Stock previously issued to Swartz Investments, LLC. Dunwoody Brokerage
Services, Inc. is a broker-dealer registered with the SEC and the National
Association of Securities Dealers, Inc. with respect to which Swartz
Investments, LLC is an Office of Supervisory Jurisdiction.

     The following table provides certain information as of June 2, 1999, with

         preceding July 15, 1999 is less than $1.375 per share, which will
         obligate Techniclone to issue a number of additional shares of Common
         Stock equal to the difference between the amount of shares which would
         have been issued for half the purchase price paid in June 1998, if the
         purchase price per share had been the 10-day low closing bid price
         immediately preceding July 15, 1999, and one-half of the amount of
         shares actually issued on June 1998.

     Under the Regulation D Common Stock Equity Line Subscription Agreement,
until June 16, 2001 Techniclone may from time to time, in its discretion and
subject to certain restrictions and limitations, sell to the two institutional
investors a number of shares of Common Stock equal to up to $2,250,000, less the
aggregate dollar amount of any shares sold to the two institutional investors
during the immediately preceding three month period. The purchase price for the
shares to be sold to the institutional investors is equal to 82.5% of the 10-day
low closing bid price immediately preceding the date of sale. However, if 82.5%
of such 10-day low closing bid price results in a discount of less than twenty
cents per share from such price, the purchase price for the shares will be equal
to such 10-day low closing bid price minus twenty cents. The number of shares
which may be sold to the two institutional investors at any one time is limited
to the same number of shares of restricted securities that the institutional
investors would otherwise be able to sell in compliance with Rule 144(e)
promulgated under the Securities Act of 1933, and is also subject to a maximum
dollar amount of $13,575,000 as of the date of this prospectus. In addition, at
the time of each sale of shares, the two institutional investors will be issued
warrants, expiring on December 31, 2004, to purchase a number of shares of
Common Stock equal to 10% of the number of shares of Common Stock sold in such
sale at an exercise price equal to the price per share at which such shares were
sold to the institutional investors. If Techniclone has not fully utilized the
relevant commitment amount under the Regulation D Common Stock Equity Line
Subscription Agreement, Techniclone may also be obligated to issue to the two
institutional investors on June 23, 1999, June 23, 2000 and June 23, 2001,
warrants to purchase a number of shares of Common Stock equal to 10% of the
difference between the relevant minimum commitment amount ($6,666,667 for 1999,
$13,333,333 for 2000 and $20,000,000 for 2001) minus the aggregate amount of
Common Stock sold to the institutional investors during all years preceding such
date.

     Under the Placement Agent Agreement, Dunwoody Brokerage Services, Inc. is
entitled to receive the following compensation as a placement agent fee in
connection with the placement and sale of securities of Techniclone to the two
institutional investors:

     o   a cash placement fee equal to 7% of the purchase price of any and all
         securities placed under the Regulation D Common Stock Equity Line
         Subscription Agreement;
     o   a non-accountable expense allowance equal to 1% of the purchase price
         of any and all securities placed up to the aggregate purchase price of
         the first $10 million of securities placed under the Regulation D
         Common Stock Equity Line Subscription Agreement;


                                       15
<PAGE>


     o   a one time non-accountable expenses allowance equal to one hundred
         thousand dollars for any and all securities placed in excess of the
         aggregate purchase price of the first $10 million of securities placed
         under the Regulation D Common Stock Equity Line Subscription Agreement;
         and
     o   an amount of securities equal to 10% of all Common Stock issued under
         the Regulation D Common Stock Equity Line Subscription Agreement and an
         amount of securities equal to 10% of all warrants issued under the
         Regulation D Common Stock Equity Line Subscription Agreement.

     Techniclone's ability to require the two institutional investors to
purchase shares of its Common Stock under the Regulation D Common Stock Equity
Line Subscription Agreement is subject to certain conditions and limitations,
including:

     o   the representations and warranties of Techniclone in the Regulation D
         Common Stock Equity Line Subscription Agreement must be true and
         correct in all material respects as of the date of each sale;
     o   Techniclone shall have performed and complied with all obligations
         under the Regulation D Common Stock Equity Line Subscription Agreement,
         the Registration Rights Agreement and the warrants issued to the two
         institutional investors required to be performed as of the date of each
         sale;
     o   no statute, rule, regulation, executive order, decree, ruling or
         injunction shall be in effect which prohibits or directly and adversely
         affects any of the transactions contemplated by the Regulation D Common
         Stock Equity Line Subscription Agreement;
     o   at the time of a sale, there shall have been no material adverse change
         in Techniclone's business prospects or financial condition, except as
         disclosed in Techniclone's most recent periodic reports filed since
         June 16, 1998 with the SEC under the Securities Exchange Act of 1934;
     o   Techniclone's Common Stock shall not have been delisted from The Nasdaq
         SmallCap Market nor suspended from trading;
     o   the closing bid price of the Common Stock on any trading during the ten
         days preceding the date of the sale cannot be less than or equal to
         $0.50; and
     o   if the closing bid price of the Common Stock on any trading day during
         the ten trading days preceding the date of the sale is less than $1.00
         but greater than $0.50, Techniclone may only require the purchase by
         the two institutional investors of an amount of shares not greater than
         15% of the amount that would otherwise be available to Techniclone
         under the Regulation D Common Stock Equity Line Subscription Agreement.

     Under the Placement Agent Agreement and a related Registration Rights
Agreement between Techniclone, the two institutional investors and Dunwoody
Brokerage Services, Inc., as successor in interest to Swartz Investments, LLC,
Techniclone has filed a registration statement, of which this prospectus forms a
part, in order to permit Dunwoody Brokerage Services, Inc. to resell to the
public the shares of Common Stock issued to Dunwoody Brokerage Services, Inc.
(including shares issuable to Dunwoody Brokerage Services, Inc. upon exercise of
outstanding warrants ) under the Placement Agent Agreement.

     The two institutional investors and Dunwoody Brokerage Services, Inc. have
agreed that they will not create or increase a net short position with respect
to the Common Stock during the ten trading days prior to any sale of shares of
Common Stock to the institutional investors or during the thirty calendar days
prior to July 15, 1999. The two institutional investors and Dunwoody Brokerage
Services, Inc. have further agreed that they will not engage in any trading
practice or activity for the purpose of manipulating the price of the Common
Stock or otherwise engage in any trading practice or activity that violates the
rules and regulations of the SEC.

                              PLAN OF DISTRIBUTION

     Techniclone has been advised by Dunwoody Brokerage Services, Inc. that all
or a portion of the shares of Common Stock offered by this prospectus may be
offered for sale, from time to time, by Dunwoody Brokerage Services, Inc. in one
or more private or negotiated transactions, in open market transactions on the
Nasdaq SmallCap Market, in settlement of short sale transactions, in settlement
of option transactions, or otherwise, or a combination of these methods, at
prices and terms then obtainable, at fixed prices, at prices then prevailing at
the time of sale, at prices related to such prevailing prices, or at negotiated
prices or otherwise. Dunwoody Brokerage Services, Inc. may effect these
transactions by selling the shares of Common Stock offered by this prospectus
directly to one or more purchasers or to or through other broker-dealers or
agents including: (a) in a block trade in which the broker or dealer so engaged
will attempt to sell the shares as agent, but may position and resell a portion
of the block as principal to facilitate the transaction; (b) in purchases by
another broker or dealer and resale by such broker or dealer as a principal for
its account; (c) in ordinary brokerage transactions and (d) in transactions in
which the broker solicits purchasers. The compensation to a particular
underwriter, broker-dealer or agent may be in excess of customary commissions.

     To Techniclone's knowledge, Dunwoody Brokerage Services, Inc. has made no
arrangement with any brokerage firm (other than itself) for the sale of the
shares of Common Stock offered by this prospectus. Techniclone has been advised
by Dunwoody Brokerage Services, Inc. that it presently intends to dispose of the
shares of Common Stock offered by this prospectus through itself or through
other broker-dealers in ordinary brokerage transactions at market prices
prevailing at the time of the sale. However, depending on market conditions and
other factors, Dunwoody Brokerage Services, Inc. may also dispose of the shares
through one or more of the other methods described above. Concurrently with
sales under this prospectus, Dunwoody Brokerage Services, Inc. may effect other
sales of the shares of Common Stock offered by this prospectus under Rule 144 or
other exempt resale transactions. There can be no assurance that Dunwoody
Brokerage Services, Inc. will sell any or all of the shares of Common Stock
offered by this prospectus.

     Dunwoody Brokerage Services, Inc. is an "underwriter" within the meaning of
the Securities Act of 1933 in connection with the sale of the shares of Common
Stock offered by this prospectus. Any other broker-dealers or agents who act in
connection with the sale of the shares of Common Stock offered by this
prospectus may also be deemed to be underwriters. Profits on any resale by
Dunwoody Brokerage Services, Inc. of the shares of Common Stock offered by this
prospectus and any discounts, commissions or concessions received by any such
broker-dealers or agents may be deemed to be underwriting discounts and
commissions under the Securities Act of 1933.

     Any broker-dealer participating in such transactions as agent may receive
commissions from Dunwoody Brokerage Services, Inc. (and, if they act as agent
for the purchaser of such shares, from such purchaser). Broker-dealers may agree
with Dunwoody Brokerage Services, Inc. to sell a specified number of shares of
Common Stock offered by this prospectus at a stipulated price per share and, to
the extent such a broker-dealer is unable to do so acting as agent for Dunwoody
Brokerage Services, Inc., to purchase as principal any unsold shares of Common
Stock at the price required to fulfill the broker-dealer commitment to Dunwoody
Brokerage Services, Inc. Broker-dealers who acquire shares of Common Stock
offered by this prospectus as principal may thereafter resell such shares from
time to time in transactions (which may involve crosses and block transactions
and which may involve sales to and through other broker-dealers, including
transactions of the nature described above) in the over-the-counter market, in
negotiated transactions or otherwise at market prices prevailing at the time of
sale or at negotiated prices, and in connection with such resales may pay to or
receive from the purchasers of such shares commissions computed as described
above. To the extent required under the Securities Act of 1933, a supplemental
prospectus will be filed, disclosing (a) the name of any such broker-dealers;

                            DESCRIPTION OF SECURITIES

     As of the date of this prospectus, the authorized capital stock of
Techniclone consists of 120,000,000 shares of Common Stock, par value $.001 per
share, and 5,000,000 shares of Preferred Stock, par value $.001 per share, of
which 10,000 shares are designated as Series B Convertible Preferred Stock
("Class B Stock") and 17,200 shares are designated as 5% Adjustable Convertible
Class C Preferred Stock ("Class C Stock"). As of June 2, 1999, there were
74,535,767 shares of Common Stock outstanding held by 5,832 stockholders of
record, 121 shares of Class C Stock outstanding held by 3 holders of record and
no shares of Class B Stock outstanding.

     Holders of Common Stock are entitled to one vote per share on all matters
to be voted upon by the stockholders. Subject to preferences that may be
applicable to the holders of outstanding shares of Preferred Stock, if any, the
holders of Common Stock are entitled to receive such lawful dividends as may be
declared by the Board of Directors. In the event of liquidation, dissolution or
winding up of Techniclone, and subject to the rights of the holders of
outstanding shares of Preferred Stock, if any, the holders of shares of Common
Stock shall be entitled to receive pro rata all of the remaining assets of
Techniclone available for distribution to its stockholders. There are no
redemption or sinking fund provisions applicable to the Common Stock. All
outstanding shares of Common Stock are fully paid and nonassessable, and shares
of Common Stock to be issued in this offering shall be fully paid and
nonassessable.

     Warrants which are currently held by Dunwoody Brokerage Services, Inc. or
which may be issued in the future to Dunwoody Brokerage Services, Inc. under the
Placement Agent Agreement are exercisable at any time beginning on the date of
issuance of such warrants and ending on December 31, 2004. The shares of Common
Stock underlying the warrants, when issued upon exercise in whole or in part,
will be fully paid and nonassessable, and Techniclone will pay any transfer tax
incurred as a result of the issuance of the Common Stock to the holder upon its
exercise.

     Each of the warrants contain provisions that protect the holder against
dilution by adjustment of the exercise price. Such adjustments will occur in the
event, among others, of a merger, stock split or reverse stock split, stock
dividend or recapitalization. Techniclone is not required to issue fractional
shares upon the exercise of any of the warrants. The holder of the warrants will
not possess any rights as a stockholder until such holder exercises the
warrants. The warrants may be exercised upon surrender on or before the
expiration date of the relevant warrant at the offices of Techniclone, with an
exercise form completed and executed as indicated, accompanied by payment of the
exercise price for the number of shares with respect to which the warrant is
being exercised. The exercise price is payable only by way of a "cashless
exercise," in which that number of shares of Common Stock underlying the warrant
having a fair market value equal to the aggregate exercise price are canceled as
payment of the exercise price.

     For the life of each of the warrants, the holder has the opportunity to
profit from a rise in the market price of the Common Stock without assuming the
risk of ownership of the shares of Common Stock issuable upon the exercise of
the warrant. The holder of the warrant may be expected to exercise the warrant
at a time when Techniclone would, in all likelihood, be able to obtain any
needed capital by an offering of Common Stock on terms more favorable than those
provided for by the warrants. Furthermore, the terms on which Techniclone could
obtain additional capital during the life of the warrants may be adversely
affected.

     This prospectus does not cover any shares of Common Stock issued or
issuable to the two institutional investors under the Regulation D Common Stock
Equity Line Subscription Agreement or shares of Common Stock issuable upon
exercise of warrants issued or issuable to the two institutional investors under
the Regulation D Common Stock Equity Line Subscription Agreement, which shares
have been separately registered for resale under the Securities Act of 1933, and
are the subject of a separate prospectus.

                                  LEGAL MATTERS

     The validity of the shares of Common Stock offered by this prospectus will
be passed upon for Techniclone by Rutan & Tucker, LLP, Costa Mesa, California.

                                     EXPERTS

     The consolidated financial statements and related consolidated financial
statement schedule, incorporated in this prospectus by reference from
Techniclone Corporation's Annual Report on Form 10-K for the year ended April
30, 1998, have been audited by Deloitte & Touche LLP, independent auditors, as
stated in their report (which expresses an unqualified opinion and includes an
explanatory paragraph regarding substantial doubt about Techniclone's ability to
continue as a going concern), which is incorporated in this prospectus by
reference, and have been so incorporated in reliance upon the report of such
firm given upon their authority as experts in accounting and auditing.

                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Techniclone's Bylaws provide that Techniclone will indemnify its directors
and officers and may indemnify its employees and other agents to the fullest
extent permitted by law. Techniclone believes that indemnification under its
Bylaws covers at least negligence and gross negligence by indemnified parties,
and permits Techniclone to advance litigation expenses in the case of
stockholder derivative actions or other actions, against an undertaking by the
indemnified party to repay such advances if it is ultimately determined that the
indemnified party is not entitled to indemnification. Techniclone has liability
insurance for its officers and directors.

     In addition, Techniclone's Certificate of Incorporation provides that,
under Delaware law, its directors shall not be liable for monetary damages for
breach of the directors' fiduciary duty as a director to Techniclone and its
stockholders. This provision in the Certificate of Incorporation does not
eliminate the directors' fiduciary duty, and in appropriate circumstances
equitable remedies such as injunctive or other forms of non-monetary relief will
remain available under Delaware law. In addition, each director will continue to
be subject to liability for breach of the director's duty of loyalty to
Techniclone for acts or omissions not in good faith or involving intentional
misconduct, for knowing violations of law, for actions leading to improper
personal benefit to the director, and for payment of dividends or approval of
stock repurchases or redemptions that are unlawful under Delaware law. The
provision also does not affect a director's responsibilities under any other
law, such as the federal securities laws or state or federal environmental laws.

     Provisions of Techniclone's Bylaws require Techniclone, among other things,
to indemnify them against certain liabilities that may arise by reason of their
status or service as directors or officers (other than liabilities arising from
actions not taken in good faith or in a manner the indemnitee believed to be
opposed to the best interests of Techniclone) to advance their expenses incurred
as a result of any proceeding against them as to which they could be indemnified
and to obtain directors' insurance if available on reasonable terms. To the
extent that indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers or persons controlling Techniclone
as discussed in the foregoing provisions, Techniclone has been informed that in
the opinion of the SEC, such indemnification is against public policy as
expressed in the Securities Act of 1933, and is therefore unenforceable.
Techniclone believes that its Certificate of Incorporation and Bylaw provisions
are necessary to attract and retain qualified persons as directors and officers.


                                       22
<PAGE>


     Techniclone has in place a directors' and officers' liability insurance
policy that, subject to the terms and conditions of the policy, insures the
directors and officers of Techniclone against losses arising from any wrongful
act (as defined by the policy) in his or her capacity as a director of officer.
The policy reimburses Techniclone for amounts which Techniclone lawfully
indemnifies or is required or permitted by law to indemnify its directors and
officers.

     ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Techniclone Corporation's Certificate of Incorporation (the "Certificate")
and Bylaws include provisions that eliminate the directors' personal liability
for monetary damages to the fullest extend possible under Delaware Law or other
applicable law (the "Director Liability Provision"). The Director Liability
Provision eliminates the liability of directors to Techniclone and its
stockholders for monetary damages arising out of any violation by a director of
his fiduciary duty of due care. However, the Director Liability Provision does
not eliminate the personal liability of a director for (i) breach of the
director's duty of loyalty, (ii) acts or omissions not in good faith or
involving intentional misconduct or knowing violation of law, (iii) payment of
dividends or repurchases or redemption of stock other than from lawfully
available funds, or (iv) any transactions from which the director derived an
improper benefit. The Director Liability Provision also does not affect a
director's liability under the federal securities laws or the recovery of
damages by third parties. Furthermore, under Delaware Law, the limitation
liability afforded by the Director Liability Provision does not eliminate a
director's personal liability for breach of the director's duty of due care.
Although the directors would not be liable for monetary damages to Techniclone
or its stockholders for negligent acts or commissions in exercising their duty
of due care, the directors remain subject to equitable remedies, such as actions
for injunction or rescission, although these remedies, whether as a result of
timeliness or otherwise, may not be effective in all situations. With regard to
directors who also are officers of Techniclone, these persons would be insulated
from liability only with respect to their conduct as directors and would not be
insulated from liability for acts or omissions in their capacity as officers.
These provisions may cover actions undertaken by the Board of Directors, which
may serve as the basis for a claim against Techniclone under the federal and
state securities laws. Techniclone has been advised that it is the position of
the SEC that insofar as the foregoing provisions may be involved to disclaim
liability for damages arising under the Securities Act of 1933, as amended (the
"Securities Act"), such provisions are against public policy as expressed in the
Securities Act and are therefore unenforceable.

     Delaware law provides a detailed statutory framework covering
indemnification of directors, officers, employees or agents of Techniclone
against liabilities and expenses arising out of legal proceedings brought
against them by reason of their status or service as directors, officers,
employees or agents. Section 145 of the Delaware General Corporation Law
("Section 145") provides that a director, officer, employee or agent of a
corporation (i) shall be indemnified by the corporation for expenses actually
and reasonably incurred in defense of any action or proceeding if such person is
sued by reason of his service to the corporation, to the extent that such person
has been successful in defense of such action or proceeding, or in defense of
any claim, issue or matter raised in such litigation, (ii) may, in actions other


                                      II-1
<PAGE>


than actions by or in the right of the corporation (such as derivative actions),
be indemnified for expenses actually and reasonably incurred, judgments, fines
and amounts paid in settlement of such litigation, even if he is not successful
on the merits, if he acted in good faith and in a manner he reasonably believed
to be in or not opposed to the best interests of the corporation (and in a
criminal proceeding, if he did not have reasonable cause to believe his conduct
was unlawful), and (iii) may be indemnified by the corporation for expenses
actually and reasonably incurred (but not judgments or settlements) of any
action by the corporation or of a derivative action (such as a suit by a
stockholder alleging a breach by the director or officer of a duty owed to the
corporation), even if he is not successful, provided that he acted in good faith
and in a manner reasonably believed to be in or not opposed to the best
interests of the corporation, provided that no indemnification is permitted
without court approval if the director has been adjudged liable to the
corporation.

     Delaware Law also permits a corporation to elect to indemnify its officers,
directors, employees and agents under a broader range of circumstances than that
provided under Section 145. The Certificate contains a provision that takes full
advantage of the permissive Delaware indemnification laws (the "Indemnification
Provision") and provides that Techniclone is required to indemnify its officers,
directors, employees and agents to the fullest extent permitted by law,
including those circumstances in which indemnification would otherwise be
discretionary, provided, however, that prior to making such discretionary
indemnification, Techniclone must determine that the person acted in good faith
and in a manner he or she believed to be in the best interests of the
corporation and, in the case of any criminal action or proceeding, the person
had no reason to believe his or her conduct was unlawful.

     In furtherance of the objectives of the Indemnification Provision,
Techniclone has also entered into agreements to indemnify its directors and
executive officers, in addition to the indemnification provided for in
Techniclone's Certificate and Bylaws (the "Indemnification Agreements").
Techniclone believes that the Indemnification Agreements are necessary to
attract and retain qualified directors and executive officers. Pursuant to the
Indemnification Agreements, an indemnitee will be entitled to indemnification to
the extent permitted by Section 145 or other applicable law. In addition, to the
maximum extent permitted by applicable law, an indemnitee will be entitled to
indemnification for any amount or expense which the indemnitee actually and
reasonably incurs as a result of or in connection with prosecuting, defending,
preparing to prosecute or defend, investigating, preparing to be a witness, or
otherwise participating in any threatened, pending or completed claim, suit,
arbitration, inquiry or other proceeding (a "Proceeding") in which the
indemnitee is threatened to be made or is made a party or participant as a
result of his or her position with Techniclone, provided that the indemnitee
acted in good faith and in a manner he or she reasonably believed to be in or
not opposed to the best interests of Techniclone and had no reasonable cause to
believe his or her conduct was unlawful. If the Proceeding is brought by or in
the right of Techniclone and applicable law so provides, the Indemnification
Agreement provides that no indemnification against expenses shall be made in
respect of any claim, issue or matter in the Proceeding as to which the
indemnitee shall have been adjudged liable to Techniclone.

     Insofar as indemnification for liabilities arising under the Securities
Act, may be permitted to directors, officers or persons controlling Techniclone
pursuant to the foregoing provisions, Techniclone has been advised that in the
opinion of the Securities and Exchange Commission, such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.

     ITEM 17. UNDERTAKINGS

     (a) The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

             (i) To include any prospectus required by Section 10(a)(3) of the
Securities Act;


                                      II-7
<PAGE>


                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the Registration
Statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total value of securities offered would not exceed
that which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in
volume and price present no more than a 20% change in the maximum aggregate
offering price set forth in the "Calculation of Registration Fee" table in the
effective Registration Statement;

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the Registration Statement or
any material change to such information in the Registration Statement;

PROVIDED, HOWEVER, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the Registration Statement.

         (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial BONA
FIDE offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at the time shall be deemed to be
the initial BONA FIDE offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 15 above, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

Brokerage Services, Inc. (the "Shares").

     In our capacity as your counsel in connection with this transaction, we
have examined the proceedings taken and are familiar with the proceedings
proposed to be taken by you in connection with the authorization and issuance of
the securities in the manner set forth in the Amended Registration Statement. We
have examined such documents as we consider necessary to render this opinion. In
such examination, we have assumed the authenticity of all documents submitted to
us as originals, the conformity with originals of all documents submitted to us
as copies and the genuineness of all signatures. We have also assumed the legal
capacity of all natural persons and that, with respect to all parties to
agreements or instruments relevant hereto other than the Company, such parties
had the requisite power and authority to execute, deliver and perform such
agreements or instruments, that such agreements or instruments have been duly
authorized by all requisite action and have been executed and delivered by such
parties and that such agreements or instruments are valid, binding and
enforceable obligations of such parties.

     Based upon the foregoing and the compliance with applicable state
securities laws by the Company and the additional proceedings to be taken by the
Company as referred to above, we are of the opinion that the Shares have been
duly authorized, and when issued by the Company upon receipt of payment therefor
(to the extent required), the Shares will be validly issued, fully paid and
nonassessable.

     Our opinions herein are limited to the effect on the subject transaction of
United States Federal law and the General Corporation Law of the State of
Delaware. We assume no responsibility regarding the applicability to or the
effect on our opinion of the laws of any other jurisdiction.

     We hereby consent to the filing of this opinion as an exhibit to the
Amended Registration Statement and to the reference to our firm contained under
the caption "Legal Matters" in the prospectus which is a part of the Amended
Registration Statement.

                                                 Respectfully submitted,

                                                 /s/ Rutan & Tucker, LLP
