                          CYTOCLONAL PHARMACEUTICS INC.

                                         
                                          


   
                        6,523,073 SHARES OF COMMON STOCK
                      2,006,073 REDEEMABLE CLASS D WARRANTS

         We are hereby registering (the "Offering") a total of 6,523,073 shares
("Shares") of our common stock, par value $.01 per share ("Common Stock"), and
2,006,073 Redeemable Class D Warrants ( "Class D Warrants," and together with
the Shares, "Securities"). The Securities were initially included in units ("IPO
Units") which we sold in our initial public offering in November 1995 ("IPO").
Each IPO Unit consisted of one share of Common Stock, one Redeemable Class C
Warrant ("Class C Warrant") and one Class D Warrant. Each Class C Warrant is
exercisable until November 2, 2000 ("Expiration Date") for one share of Common
Stock at an exercise price of $6.50 per share, subject to adjustment in certain
circumstances, and one Class D Warrant. Each Class D Warrant is exercisable
until the Expiration Date for one share of Common Stock at an exercise price of
$8.75 per share, subject to adjustment in certain circumstances. Included in the
Securities sold in this Offering are (i) 2,006,073 shares of Common Stock
issuable upon the exercise of the Class C Warrants, (ii) 2,006,073 Class D
Warrants issuable upon the exercise of the Class C Warrants (iii) 2,006,073
shares of Common Stock issuable upon the exercise of such Class D Warrants and
(iv) 2,510,927 shares of Common Stock issuable upon the exercise of the Class D
Warrants. Since November 2, 1996, we have had the right to redeem the Class C
Warrants and the Class D Warrants (collectively, the "Warrants") at a redemption
price of $.05 per Warrant, upon at least 30 days' prior written notice if the
average closing bid price of our Common Stock, as reported by the National
Association of Securities Dealers Automated Quotation System ("Nasdaq") (or the
last sale prices if listed on the Nasdaq National Market or a securities
exchange), exceeds $9.10 per share for the Class C Warrants, subject to
adjustment, or $12.25 per share for the Class D Warrants, subject to adjustment,
for 30 consecutive business days ending within 15 business days of the date on
which notice of redemption is given. See "Description of Securities-Class C
Warrants and Class D Warrants."

         We have agreed to pay a solicitation fee (the "Solicitation Fee") to
Janssen-Meyers Associates, L.P. ("JMA") equal to 5% of the aggregate exercise
price of the Warrants. The exercise prices and other terms of the Warrants were
arbitrarily determined by negotiation between us and the underwriters of the
IPO, of which JMA was one of the syndicate managers (collectively, the
"Underwriters"), and are not necessarily related to our assets, book value or
financial condition, or to any other recognized criteria of value. See "Risk
Factors -- Arbitrary Determination of Offering Price." Our Common Stock is
quoted on the Nasdaq SmallCap Market System ("Nasdaq-SCM") under the symbol,
"CYPH". Our Class C Warrants are quoted on Nasdaq-SCM under the symbol, "CYPHW."
Our Class D Warrants are quoted on Nasdaq-SCM under the symbol, "CYPHZ."

                               PROSPECTUS SUMMARY

   
         This summary highlights information contained elsewhere in this
prospectus. This summary is not complete and may not contain all of the
information that you should consider before investing in the Securities. You
should read the entire prospectus carefully. Unless we otherwise say so, when we
discuss outstanding securities of the Company, we exclude all of the shares of
Common Stock issuable upon the exercise of the Company's currently outstanding
warrants and options and the conversion of the Company's convertible securities.
    

                          CYTOCLONAL PHARMACEUTICS INC.

   
         We are a biopharmaceutical company located in Dallas, Texas. Our goal
is to develop products to identify, treat and prevent cancer and other diseases.
We were formed in September 1991 and since that date, we have devoted our
resources solely to research and development activities relating to several
products which are at various developmental stages. We have several license
agreements with various biopharmaceutical companies and research institutions
which own approved and pending patents covering certain drugs and therapeutic
technologies.
    

   
                                    STRATEGY
    

   
         Through our research and development efforts and agreements with other
research institutions and biotechnology companies, we have acquired and
developed rights to certain technology. At the present time, we are focusing our
attention and resources on our collaboration agreement with Bristol-Myers Squibb
Company, Inc. ("Bristol-Myers Squibb") for Paclitaxel production (the "BMS
License Agreement"). Paclitaxel is a drug which has proven to be effective in
treating refractory ovarian, breast and non-small cell lung cancer and Kaposi's
Sarcoma. In addition, Paclitaxel has shown potential in treating other cancer
indications in preliminary clinical trials. Presently, Paclitaxel is made from
the inner bark and needles of the slow-growing Pacific yew tree. Our scientists
are working in cooperation with Bristol-Myers Squibb and the inventors of the
fungal Paclitaxel technology to develop a system for manufacturing Paclitaxel in
commercial quantities and at lower costs compared to currently available
production methods (the Company's "Paclitaxel Fermentation Production System").
We are also focusing on possible Paclitaxel treatment of Polycystic Kidney
Disease, Quantum Core Technology-for mechanism-based drug design, our gene
discovery program for the early diagnosis and treatment of lung cancer, vaccine
program, and antiestrogen peptide for breast cancer. Other programs, which
involve potential anti-leukemia drugs and drugs called "anti-sense
therapeutics," are being pursued at modest levels, and may help us develop
future products or alternatives to our main programs if unforeseen problems
develop. "Anti-sense therapeutics" are drugs designed to essentially "turn off"
genes involved in different diseases and to prevent such genes from growing or
duplicating. See "Risk Factors-Our Dependence Upon Agreements and Licenses with
Other Companies and Institutions; -Our Obligations to Pay Royalty Fees and the
Possibility of Losing Our Patents or Other Rights; -No Assurance of FDA
Approval; Government Regulation; and -Our Dependence upon Bristol-Myers Squibb."

         To date, our strategy has been to license technologies in their early
development stages from research and educational institutions and further
develop such technologies to the point where we can then sublicense them to
commercial entities, as we have done with our Paclitaxel production system to
Bristol-Myers Squibb. In the event we decide to expand our strategy to include
developing acquired technologies to commercial stages, which we have not done to
date, we would require significant additional money to complete development of
and obtain regulatory approvals for our proposed products which, if ever
received, may take several years. See "Risk Factors-Our Need for Substantial
Additional Funds; and -No Assurance of FDA Approval; Government Regulation."

                                 KEY AGREEMENTS

         Effective January 4, 1999, we acquired proprietary technology for
rational based drug design (the "Quantum Core Technology(TM)") developed by
Dorit Arad, Ph. D. and employed Dr. Arad as Vice President of Drug Design.

         In December 1998, we obtained an exclusive license to technology for
the fungal production of Telomerase, the so-called "immortality enzyme," from
the Research & Development Institute at Montana State University ("RDI").

         In August 1998, we entered into an exclusive world-wide license
agreement with the University of California, Los Angeles for domestic and
foreign patents and patents pending based upon and including any subject matter
claimed in or covered by a U.S. patent pending entitled, "Peptide Antiestrogen
Compositions and Methods for Treating Breast Cancer." The agreement grants us
the right to (i) make, use, sell, offer for sale, import certain products and
practice any process or method involving the patents and (ii) sublicense these
rights to third parties. Under this agreement, we have to pay up-front fees,
maintenance fees, royalties and milestone payments. See "Risk Factors-Our
Obligations to Pay Royalty Fees and the Possibility of Losing our Patent and
Other Rights."

         In June 1998, we entered into the BMS License Agreement where we
sublicensed to Bristol-Myers Squibb the technologies we had licensed from RDI
and WSURF (see the next two paragraphs for a further description of these two
agreements) relating to the production of Paclitaxel, the active ingredient in
Bristol-Myers Squibb's largest-selling cancer product, Taxol(R). Under this
agreement, Bristol-Myers Squibb has to pay us fees, milestone payments, research
and development support and minimum and sales-based royalties. See "Risk
Factors-Our Obligations to Pay Royalty Fees and the Possibility of Losing our
Patent and Other Rights; and -Our Dependence upon Bristol-Myers Squibb."

         In June 1993, we entered into an exclusive world-wide license agreement
with RDI to use patented fungal technology to manufacture Paclitaxel. In May
1998, we amended this agreement to require us to pay a percentage of royalties
received with respect to the manufacture, use or sale of the inventions by
sublicensees and all up-front, milestone and royalty payments we may receive
under the BMS License Agreement. See "Risk Factors-Our Obligations to Pay
Royalty Fees and the Possibility of Losing our Patent and Other Rights"

         In July 1996, we entered into an exclusive, world-wide license
agreement with the Washington State University Research Foundation ("WSURF") to
use and sublicense patented technology or prospective patented technology
related to genes and associated products for the manufacturing of Paclitaxel
from the yew tree. In June 1998, we amended this agreement to cover additional
patents, patent applications and genes for enzymes which are expected to be the
subject of future patent filings and allow us to license any of the technology
as it is developed until July 2006. See "Risk Factors-Our Obligations to Pay
Royalty Fees and the Possibility of Losing our Patent and Other Rights."

         In June 1996, we entered into an exclusive license agreement with the
University of Texas System to allow us to manufacture, have manufactured, use,
sell and sublicense products related to a U.S. Patent Application entitled, "A
Method for Ranking Sequences to Select Target Sequence Zones of Nucleus Acids."
The technology has identified specific areas within genes which would be
receptive to anti-sense products. A patent issued in 1999. This discovery has
potentially broad applications to many human and viral genes involved in human
disease. See "Risk Factors-Our Obligations to Pay Royalty Fees and the
Possibility of Losing Our Patent and Other Rights."

         In February 1996, we obtained exclusive rights to a technology and then
pending patent developed at the University of California, Los Angeles for the
Paclitaxel treatment of Polycystic Kidney Disease. The Patent and Trademark
Office ("PTO") issued a patent in 1998. See "Risk Factors-Our Obligations to Pay
Royalty Fees and the Possibility of Losing our Patent and Other Rights."

                                FINANCIAL HISTORY

         Until the fiscal year ended December 31, 1997, we had not generated any
sales revenues. In fiscal year ended

<PAGE>   6

   
December 31, 1998, however, we, for the first time, generated $1,183,000 in
revenues from Bristol-Myers Squibb pursuant to the BMS License Agreement. We,
however, have experienced operating losses of $3,106,000 for the fiscal year
ended December 31, 1996; $3,357,000 for the fiscal year ended December 31, 1997
and $3,009,000 for the fiscal year ended December 31, 1998. Since our formation
in 1991, we have incurred significant net operating losses, and we cannot
predict when, if ever, this trend will end. See "Risk Factors-Our Accumulated
Deficit and Loss per Share of Common Stock; Our History of Significant Losses
and Expected Future of Significant Losses."


                             ORGANIZATIONAL HISTORY

                                  RISK FACTORS

         You should carefully consider the following factors and other
information in this prospectus before deciding to invest in the Company's
Securities being offered hereby.

OUR ACCUMULATED DEFICIT AND LOSS PER SHARE OF COMMON STOCK.

         We had an accumulated deficit of $15,104,000 as of the fiscal year
ended December 31, 1997 and $17,832,000 as of the fiscal year ended December 31,
1998. Our statement of operations for the fiscal year ended December 31, 1997
shows net losses of $3,252,000, which means a loss of $.42 per share of Common
Stock. Our statement of operations for the fiscal year ended December 31, 1998
shows net losses of $2,728,000, which means a loss of $.30 per share of Common
Stock. See "-Our History of Significant Losses and Expected Future of
Significant Losses."

OUR HISTORY OF SIGNIFICANT LOSSES AND EXPECTED FUTURE OF SIGNIFICANT LOSSES.

         Until June 30, 1998, we were a "development stage" company. However,
because we had revenues of $1,183,000 in the fiscal year period ended December
31, 1998 pursuant to the BMS License Agreement, we are no longer considered to
be a "developmental stage" company. However, from our formation in 1991 to the
date of this prospectus, we have had substantial operating losses and expect to
have them for the next several years, if not more, due to our research and
development activities and general and administrative expenditures. Although we
had revenue in 1998, we cannot say with any certainty that we will any have
future revenue, or that even if we do have revenue, that we will be profitable.
See "-Our Accumulated Deficit and Loss per Share of Common Stock."

OUR NEED FOR SUBSTANTIAL ADDITIONAL FUNDS.

         Since our formation in 1991, we have experienced negative cash flows
from our operations which means we are spending more money than we are
receiving. We also expect to experience negative cash flows in the foreseeable
future. Since our formation in 1991, we have relied on loans, private
financings, and our IPO completed in November 1995 to allow us to continue our
operations. Our cash requirements in the future may be significantly different
from our current estimates because of changes in our research and development
programs, increased competition, advances in technology and other factors.

         We do not have any commitments or arrangements to obtain any additional
funding besides the BMS License Agreement. We cannot say with any certainty that
required financing will be available to us on favorable terms, if at all.
Although we plan to seek funding for some of our product development efforts by
entering into research and development partnerships and obtaining government
grants and research contracts, we cannot say with any amount of certainty that
we will be able to enter into any additional agreements on favorable terms, if
at all. If we decide to raise additional money by issuing more of our
securities, stockholders at the time of the issuance will experience a dilution
to the value of their securities.

OUR DEPENDENCE UPON AGREEMENTS AND LICENSES WITH OTHER COMPANIES AND
INSTITUTIONS.

         Our strategy is to develop, test, manufacture and eventually
commercialize our products. This will require us to enter into agreements with
other companies and institutions. As of the date of this Prospectus, we have
entered into key license and collaborative agreements with Bristol-Myers Squibb,
Enzon, RDI, UCLA, Enzon, WadTech, WSURF and the University of Texas and entered
into a joint venture agreement with Pestka Biomedical Laboratories, Inc. In
general, our collaborative agreements with other companies and research
institutions provide that the agreements may be terminated under certain
circumstances. We cannot give any assurance that we will be able to extend any
of our collaborative agreements upon their termination or expiration, or that we
will be able to enter into new collaborative agreements with existing or new
partners in the future. To the extent we decline or are unable to enter into any
additional collaborative arrangements, we would require substantially greater
funding to continue our current activities.
    

                                        7

<PAGE>   10

   
In addition, if we are unable to enter into additional collaborative agreements,
we might be significantly delayed in introducing our proposed products into
certain commercial markets, or we may even find that our development,
manufacture or sale of our proposed products is greatly hurt. If we enter into
additional agreements, we will rely upon the other parties to honor their
responsibilities and perform their obligations under the agreements. We cannot
say with any certainty that our current agreements or any future agreements will
allow us to develop products with commercial potential or to obtain proprietary
rights or licenses for proprietary rights with respect to any technology
developed in connection with these arrangements or that we will be able to
guarantee the confidentiality of any proprietary rights and information
developed under such collaborative arrangements or prevent their public
disclosure. See "-Our Obligations to Pay Royalty Fees and the Possibility of
Losing our Patents and Other Rights; -Our Competition; -Our Uncertain Ability to
Protect Our Technology; and -Our Dependence upon Bristol-Myers Squibb" and
"Business."

WE MIGHT EXPERIENCE PROBLEMS IN DEVELOPING OUR PRODUCTS.

         We cannot say with any certainty that our research and development
activities will enable us to produce any products able to withstand competition.
Our development of each product is subject to the risks of failure commonly
experienced in the development of products based upon innovative technologies
and the expense and difficulty of obtaining approvals from regulatory agencies.
All of our potential products currently under development will require
significant additional funding and development and pre-clinical and clinical
testing before we are able to submit them to any of the regulatory agencies for
approval for commercial use. We cannot say with any certainty that we will be
able to license any technologies or proposed products or to complete
successfully any of our research and development activities. Even if we do
complete them, we cannot say with any certainty that we will be able to market
successfully any of the products or that we will be able to obtain the necessary
regulatory approval or that customers will like our products. We also face the
risk that any or all of our products will not work as intended or that they will
be toxic, or that, even if they do work and are safe, that our products will be
difficult to manufacture or market on a large scale. We also face the risk that
the rights of other persons or entities will stop us from marketing any of our
products or that other persons or entities might market their products as well
as we market our products or even better. See "-Our Competition; -No Assurance
of FDA Approval; Government Regulation; -Our Dependence upon Others for
Manufacturing; Our Lack of Manufacturing Experience; and -Our Dependence upon
Others for Marketing; Our Lack of Marketing Experience."

OUR OBLIGATIONS TO PAY ROYALTY FEES AND THE POSSIBILITY OF LOSING OUR PATENTS
OR OTHER RIGHTS.

         RDI.

         Under our license agreement with RDI (the "RDI Agreement") relating to
the production of Paclitaxel, we have to pay RDI a minimum royalty fee of
$100,000 no later than June 10th of every year as long as the RDI Agreement is
in effect. We have paid RDI royalty payments of $100,000 on June 10, 1997 and
$100,000 on June 10, 1998. Also, under the RDI Agreement, we have to pay RDI
royalties on sales of products which use the technology we have licensed under
the RDI Agreement. The royalty percentage is higher if a patent for the
technology has been issued by the PTO. In May 1998, we amended the RDI Agreement
to require us to pay RDI (i) a percentage of royalties received by us from
sublicensees who manufacture, use or sell products using the technology licensed
to us under the RDI Agreement, which royalty rate will be reduced if we are
required to pay royalties to other parties, and (ii) payments we might receive
under the BMS License Agreement. Our business would be significantly hurt if we
lost the RDI Agreement. See "-Our Dependence upon Bristol-Myers Squibb."

         WadTech.

         Under our agreement with WadTech where we purchased certain of their
technology (the "Wadley Technology"), we are required to pay WadTech a royalty
fee of 6.25% of the gross selling prices of products which use any of the Wadley
Technology until we have paid to WadTech a total of $1,250,000. After that, the
royalty rate will drop to 3.75%. We have paid WadTech royalty fees of $31,250
for the year beginning October 1, 1996 and $62,500
    

                                        8

<PAGE>   11

   
for the year beginning October 1, 1997. We have to pay WadTech $125,000 for
each year after that. WadTech has a perfected security interest in the Wadley
Technology to secure the payment of the first $1,250,000 of royalties. WadTech
still has the right to license the WadTech Technology to other parties or sell
it if we do not satisfy obligations. We have to pay a royalty fee of 3% on
sales of products produced through a system involving technology concerning
yeast which was assigned to us when we purchased the Wadley Technology. Our
business would be significantly hurt if we lost the WadTech Technology.

         WSURF.

         Under our license agreement with WSURF, we are required to pay WSURF an
annual license fee every year, beginning July 1, 1997, as well as royalty and
sublicensing fees. We have paid last year's annual license fee. Our business
would be significantly hurt if we lost the technology under this license
agreement with WSURF. See "-Our Dependence upon Bristol-Myers Squibb."

         Enzon.

         Under the Enzon Agreement, if we and Enzon decide to develop any
products together, the costs and profits of the development will be split
equally. The agreement also says that if we are unable to pay our share of the
costs, we will lose our rights to any of the products which are developed and we
will not have the right to split the profits from any of the products which are
developed. We will only be entitled to a royalty fee. Our business would be
significantly hurt if we lost the Enzon Agreement. See "-Our Dependence upon
Agreements and Licenses with Other Companies and Institutions."

         University of Texas.

         Under our agreement with the University of Texas, we have paid the
University $273,213 of the $285,240 which we owe them as of December 31, 1998
when we and the university amended the agreement to grant us the right to
develop and commercialize any intellectual property under the original agreement
and which requires that we and the University negotiate a royalty fee which is
less than 8% of the net sales of any commercialized products. We also entered
into a Patent License Agreement with the Board of Regents of the University of
Texas which requires us to pay Regents licensing and sublicensing fees. Our
business would be significantly hurt if we lost any of our agreements with the
University of Texas.

         University of California, Los Angeles.

         We have three separate license agreements with the University of
California, Los Angeles ("UCLA"). Under our first license agreement with UCLA,
we have paid them $5,000, and have agreed to pay an additional $10,000 upon
issuance of a patent. Under our second license agreement with UCLA, we have paid
them a $5,000 license issuance fee, and we have agreed to pay an additional
$5,000 upon the issuance of a patent. Under our third license agreement with
UCLA, we have agreed to pay them a $20,000 license issuance fee, an additional
$25,000 fee upon the issuance of a patent, annual maintenance fees which
increase every year and minimum annual royalty payments. Our business would be
substantially hurt if we lose any of our agreements with UCLA.

OUR COMPETITION.

         We are in the rapidly changing, competitive and heavily regulated
biotechnology industry which makes it difficult for us to predict our risks and
expenses with any amount of certainty. Many of our competitors have more
financial, technical, human and other resources than us. Also, many of our
competitors have significantly more experience than us in performing
pre-clinical testing and human clinical trials of new products and obtaining
approvals from the United States Food and Drug Administration ("FDA"), PTO and
other regulatory agencies. It is a possibility that our competitors may receive
FDA or PTO approval before us and at less cost. Also, our employees and
management
    

                                       9

<PAGE>   12

   
have little or no experience producing and selling any pharmaceutical or
biological products. Investors should be aware that in June 1991, the National
Cancer Institute ("NCI") entered into a Collaborative Research and Development
Agreement ("CRADA") with Bristol-Myers Squibb to develop Paclitaxel and granted
Bristol-Myers Squibb the exclusive use of NCI's clinical data relating to
Paclitaxel in seeking approval from the FDA until December 1997, which
significantly shortened the approval process and prevented any other party from
obtaining FDA approval using the NCI data. Although Bristol-Myers Squibb has
since lost its right of exclusivity under the CRADA, it has patented its method
of delivering Paclitaxel intravenously to a patient. Such patent has in fact
kept Bristol-Myers Squibb's use of the NCI data exclusive. Other companies are
currently contesting the exclusivity in the courts. Bristol-Myers Squibb also
received FDA approval for commercial sale of its Paclitaxel for refractory
ovarian cancer in December 1992, refractory breast cancer in August 1994,
Kaposi's Sarcoma in August 1997 and lung cancer in 1998. Since December 1992,
Bristol-Myers Squibb has been the sole source of Paclitaxel for commercial
purposes. We think that Bristol-Myers Squibb is currently conducting clinical
trials in order to get FDA approval for treating other types of cancer. See "-No
Assurance of FDA Approval, Government Regulation; -Our Dependence upon
Bristol-Myers Squibb; -Our Dependence upon Others for Manufacturing; Our Lack of
Manufacturing Experience; -Our Dependence upon Other for Marketing; Our Lack of
Marketing Experience; and -Our Dependence upon Key Personnel and Collaborators;
Our Limited Management Team."

OUR UNCERTAIN ABILITY TO PROTECT OUR TECHNOLOGY.

         Our success will depend, in part, on our ability to get patent
protection for our products and processes in the United States and elsewhere. We
have filed and intend to continue to file patent applications as we need them.
We cannot say with any certainty, however, that any additional patents will
issue from any of these applications or, if patents do issue, that the claims
allowed will be sufficiently broad to protect our technology. Also, we cannot
say with any certainty that any patents issued to us or licensed by us can
withstand challenges made by others or that we will able to protect our rights.
See "-Our Competition; and -Our Dependence upon Key Personnel and Collaborators;
Our Limited Management Team."

         We are aware of patent applications and issued patents belonging to our
competitors, and we are uncertain whether any of these, or of any patent
applications which we do not know about, will require us to alter or cease our
potential products or processes. We cannot say with any certainty that we will
be able to obtain any licenses to technology that we will require or, if
obtainable, that the cost of them will be reasonable. Our failure to obtain any
necessary licenses to any technology could substantially hurt our business.
Expensive and drawn-out litigation may also be necessary for us to assert any of
our rights or to determine the scope and validity of rights claimed by other
parties. Litigation could be too expensive for us to pursue without great cost
and uncertainty as to the outcome. Our failure to pursue litigation could result
in the loss of our rights which could substantially hurt our business. See "-Our
Competition; and -Our Dependence upon Key Personnel and Collaborators; Our
Limited Management Team."

         We also rely on trade secrets and confidential information which we try
to protect by entering into confidentiality agreements with other parties. We
cannot say with any certainty that any of the confidentiality agreements will
honored, or, if breached, we would have enough remedies to protect the
confidential information, or that our competitors will not independently learn
our trade secrets. The loss of our trade secrets would substantially hurt our
business. See "-Our Competition; and -Our Dependence upon Key Personnel and
Collaborators; Our Limited Management Team."

NO ASSURANCE OF FDA APPROVAL; GOVERNMENT REGULATION.

         The FDA and other similar agencies in foreign countries have
substantial requirements for therapeutic and diagnostic pharmaceutical and
biological products. Such requirements often involve lengthy and detailed
laboratory and clinical testing procedures, sampling activities and other costly
and time-consuming procedures. It often takes companies several years to satisfy
these requirements, depending on the complexity and novelty of the product. The
review process is also extensive which may delay the approval process even more.
These regulatory requirements could
    

                                       10

<PAGE>   13

   
substantially hurt our ability to clinically test and manufacture our potential
products. Government regulation could also delay our marketing of new products
for a considerable period of time, impose costly procedures upon our activities
and give our competitors an advantage. We cannot say with any certainty that the
FDA or other regulatory agency will grant us approval for any of our products on
a timely basis, if at all. Any delay in obtaining, or failure to obtain, such
approvals could substantially hurt our marketing of any proposed products and
our ability to earn product revenue. Further, regulation is subject to change.
Any additional regulation could limit or restrict our ability to use any of our
technologies which could substantially hurt our operations. See "-Our
Competition."

         We also have to comply with the Occupational Safety and Health
Administration ("OSHA"), Environmental Protection Agency ("EPA"), Toxic
Substances Control Act, Resource Conservation and Recovery Act and other
regulatory laws. In the future, we could also be subject to other federal, state
or local regulations. OSHA or the EPA may establish regulations which could
affect our research and development programs. We are unable to predict whether
any agency will adopt any rule which could substantially hurt our business. See
"-Our Competition."

UNCERTAINTY RELATED TO HEALTH CARE REIMBURSEMENT AND REFORM MEASURES.

         Our success in developing our products may depend, in part, on whether
we will be reimbursed by government health administration authorities, private
health insurers and other organizations. There is significant uncertainty if
costs associated with newly-approved health care products will be reimbursed. We
cannot say with any certainty whether sufficient insurance coverage will be
available for us to establish and maintain price levels sufficient to realize an
appropriate return on developing new products. Government and other third-party
payers are attempting to contain health care costs more every day by limiting
both coverage and the level of reimbursement of new therapeutic and diagnostic
products approved for marketing by the FDA and by refusing, in some cases, to
provide any coverage of uses of approved products for disease indications for
which the FDA has not granted marketing approval. If adequate coverage and
reimbursement levels are not provided by government and third-party payers for
uses of our products, it will make it very difficult for us to market our
products to doctors and hospitals because their patients might not be able to
pay for the products without any insurance coverage or reimbursement. See "-Our
Competition; and -No Assurance of FDA Approval, Government Regulation."

OUR DEPENDENCE UPON BRISTOL-MYERS SQUIBB.

         In June 1998, we entered into the BMS License Agreement and a Sponsored
Research Agreement (the "R&D Agreement") with Bristol-Myers Squibb. Under the
BMS License Agreement, we granted Bristol-Myers Squibb an exclusive sublicense
under the RDI Agreement (the "BMS License Agreement-RDI Sublicense Agreement")
and the WSURF Agreement. Under the RDI Agreement, we acquired a license to
certain patents and technology relating to the use of microorganisms to produce
Paclitaxel and other taxanes and components. Under the WSURF Agreement, we
acquired a license to certain patents and technology relating to genes related
to enzymes involved in the production of Paclitaxel and other taxanes. The BMS
License Agreement requires Bristol-Myers Squibb to pay royalties based on the
amount of sales and lump sum payments when certain events occur. Under the BMS
License Agreement, Bristol-Myers Squibb has the right to negotiate with us
before anyone else does, an exclusive, world-wide right to license or sublicense
any of the technology licensed to us under the RDI Agreement and WSURF Agreement
and potentially new anti-cancer drugs from microorganisms supplied by us. The
term of the BMS License Agreement shall end until the occurrence of later of (i)
ten (10) years from the first commercial sale of the licensed products or (ii)
such time as neither the making, use nor sale at the time by Bristol-Myers
Squibb, its affiliates or sublicensees in such country of the licensed product
does not infringe (a) any U.S. or foreign patents or patent applications,
including reissues, renewals, extensions, continuations or
continuations-in-part, copyrights or trademarks owned and licensed by RDI to us
under the RDI Agreement, (b) certain U.S. and foreign patents or patent
applications owned by WSURF and licensed by WSURF to us under the WSURF
Agreement and (c) other licensed property together with all patent rights
pertaining thereto, to the extent that such patent rights are not already part
of the RDI Agreement and WSURF Agreement. Bristol-Myers Squibb can terminate the
BMS License Agreement after December 12, 1998, after they have given us ninety
(90) days notice, in which event the Bristol-Myers Squibb sublicense under the
RDI Agreement and WSURF Agreement will
    

                                       11

<PAGE>   14

   
terminate, although any payment obligations would survive termination. We cannot
say with any certainty that Bristol-Myers Squibb will successfully manufacture
or market the licensed property, if it does at all, or that we will be able to
maintain the RDI Agreement or the WSURF Agreement. See "-Our Dependence upon
Agreements and Licenses with Other Companies and Institutions."

         Bristol-Myers Squibb can renew the R&D Agreement for continuous
one-year periods only if the BMS License Agreement is still in effect. The R&D
Agreement contemplates, without assurance, a program to develop microbial
fermentation and genetic engineering technologies for the production of
Paclitaxel and other taxanes. See "-Our Dependence upon Agreements and Licenses
with Other Companies and Institutions."

OUR DEPENDENCE UPON OTHERS FOR MANUFACTURING; OUR LACK OF MANUFACTURING
EXPERIENCE.

         We currently do not have facilities or personnel capable of
manufacturing any products in commercial quantities. Pursuant to the BMS License
Agreement and a sub-license between us and Bristol-Myers Squibb, Bristol-Myers
Squibb has the world-wide exclusive right to utilize the technology licensed to
us by RDI pursuant to the RDI Agreement to produce, have made and/or sell
Paclitaxel (to be commercialized as Taxol(R)) and other taxanes and compounds,
although no assurances can be given. Also pursuant to the BMS License Agreement
and a sublicense between us and Bristol-Myers Squibb, Bristol-Myers Squibb has
the world-wide exclusive right to practice the technology licensed to us by
WSURF pursuant to the WSURF Agreement to make, have made, use, lease and sell
the products covered in the WSURF Agreement, although no assurances can be
given. Notwithstanding, we cannot say with any certainty whether we will be able
to enter into any future arrangements with additional outside manufacturers on
terms favorable to us, if at all. In the future, we may, if it becomes
economically attractive to do so, establish our own manufacturing facilities to
produce other products that we may develop. Building and operating production
facilities would require substantial additional funds and other resources. We
cannot say with any certainty, however, whether such funds would be available on
favorable terms to us, if at all. Also, we cannot say with any certainty whether
we will be able to shift successfully our operations to commercial development.
See "-Our Dependence upon Agreements and Licenses with Other Companies and
Institutions; and -Our Dependence upon Bristol-Myers Squibb" and
"Business-Collaborative Agreements-Bristol Myers Squibb; -RDI and -WSURF."

OUR DEPENDENCE UPON OTHERS FOR MARKETING; OUR LACK OF MARKETING EXPERIENCE.

         We currently have no marketing and sales personnel and no experience in
marketing pharmaceutical products. We would have to spend significant funds and
dedicate a significant amount of management resources to develop our own sales
force. We cannot say with any certainty that any funds or resources to develop
our own sales force will be available. Further, we cannot say with any certainty
that, with a sales force, we would successfully penetrate the markets for any of
our products. For certain products under development, we may seek to enter into
marketing agreements with other entities which would grant them exclusive
marketing rights in return for royalties based on sales, if any. Under some of
these agreements, the other entity may have the responsibility for all or a
significant part of the development and obtaining regulatory approval. In the
event that the marketing and development partner fails to develop a marketable
product or fails to successfully market a product, our business could be
substantially hurt. The sale of certain products outside the United States will
also be dependent upon the successful completion of arrangements with future
partners, licensees or distributors in each territory. We cannot give any
assurance, however, that we will successfully establish any additional
collaborative arrangements, or that, if established, such future partners will
successfully commercialize any products, if at all.

OUR DEPENDENCE UPON KEY PERSONNEL AND COLLABORATORS; OUR LIMITED MANAGEMENT
TEAM.

         Much of our success depends upon the continued contributions of our
executive officers, scientific and technical personnel and consultants. We are
particularly dependent upon Arthur P. Bollon, Ph.D., our Chairman of our Board
of Directors, Chief Executive Officer and President, and Daniel Shusterman, our
Vice President of Operations, Treasurer and Chief Financial Officer, Dorit Arad,
Ph.D., our Vice President of Drug Design, as well as our senior
    

                                       12

<PAGE>   15

   
scientists, Susan L. Berent, Ph.D., Hakim Labidi, Ph.D., Rajinder S. Sidhu,
Ph.D. and Richard M. Torczynski, Ph.D. As of April 5, 1999, we had 19 full-time
employees, 15 of whom are engaged directly in research and development
activities, including 8 Ph.D.s, and 4 of whom are in executive and
administrative positions. Our employees are not governed by any collective
bargaining agreement, and we believe that our relationship with our employees is
good. We currently have an employment agreement with Dr. Bollon which expires on
November 6, 2003. Although we maintain "key person" life insurance which
provides that upon the death or incapacity of Dr. Bollon, we will receive $2
million, Dr. Bollon's death or incapacity could substantially hurt our business.
During our limited operating history, many important responsibilities within the
Company have been assigned to a relatively small number of individuals. The
competition for qualified personnel is intense, and the loss of services of
certain key personnel could substantially hurt the Company. See "Business-Human
Resources" and "Management."

         Our scientific collaborators and advisors are employed by companies and
institutions other than us, and some of them have consulting or other advisory
arrangements with other entities and institutions which could conflict or
compete with their obligations to us. Inventions or processes discovered by such
persons will not necessarily become the property of us but may remain the
property of such persons or of such persons' full-time employers. See
"Management."

PRODUCT LIABILITY INSURANCE.

         Our products, either when using them in clinical trials or when
marketing them, could expose us to product liability claims. Although we intend
to obtain product liability insurance for our ongoing clinical trials, we cannot
say with any certainty that we will be able to obtain, maintain or increase our
insurance coverage in the future on terms favorable to us, if at all, or that
any claims against us will not be greater than the amount of such coverage.
Furthermore, certain distributors of pharmaceutical and biological products
require minimum product liability insurance coverage as a condition before they
start purchasing or accepting products for distribution. Our failure to satisfy
such insurance requirements could decrease our ability to achieve broad
distribution of our proposed products, which could substantially hurt our
business.

CONTROL OF THE COMPANY; ABILITY TO DIRECT MANAGEMENT.

         Our current officers, directors and stockholders who own more than 5%
of our securities beneficially own or control approximately 50.8% of our
outstanding shares of Common Stock, which represents approximately 48.2% of our
total outstanding voting securities. Such officers, directors and principal
stockholders may, therefore, be able to elect all of our directors, to determine
the outcome of most corporate actions requiring stockholder approval, and
otherwise to control the direction of our business. Such control could prevent
another party from trying to acquire a majority position in our business which
could potentially otherwise cause the price of our securities to increase. In
addition, our Board of Directors is authorized to issue from time to time shares
of preferred stock, without stockholder authorization, in one or more designated
series or classes. See "-Possible Restriction on 'Market Making' Activities in
the Company's Securities; Illiquidity; -Description of Securities; and "Selling
Stockholders."

OUR DIVIDEND POLICY.

         Since our formation in 1991, we have not paid any dividends on our
Common Stock. We intend to retain future earnings, if any, to provide funds for
the operation of our business and, accordingly, do not anticipate paying any
cash dividends on our Common Stock in the future. Furthermore, the terms of our
outstanding Series A Preferred Stock do not allow for the payment of cash
dividends on the Common Stock unless and until all accrued and unpaid dividends
on the Series A Preferred Stock shall have been paid or set apart for payment.

INDEMNIFICATION OF OFFICERS AND DIRECTORS.

         We are currently a Delaware corporation. Our Certificate of
Incorporation includes certain provisions permitted
    

                                       13

<PAGE>   16

   
under the Delaware General Corporation Law ("DGCL") whereby our officers and
directors are indemnified against certain liabilities. Our Certificate of
Incorporation also limits, to the fullest extent permitted by the DGCL, a
director's liability for monetary damages for breach of fiduciary duty,
including gross negligence, except liability for (i) breach of the director's
duty of loyalty, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of the law, (iii) the unlawful
payment of a dividend or unlawful stock purchase or redemption and (iv) any
transaction from which the director derives an improper personal benefit. The
DGCL does not eliminate a director's duty of care and this provision has no
effect on the availability of equitable remedies such as injunction or
rescission based upon a director's breach of the duty of care. In addition, an
insurance policy, which provides for coverage for certain liabilities of its
officers and Directors has been issued to us.

POSSIBLE RESTRICTION ON "MARKET MAKING" ACTIVITIES IN THE COMPANY'S SECURITIES;
ILLIQUIDITY.

         Upon the completion of this offering, Bruce Meyers and Peter Janssen
will beneficially own approximately 11.6% and 8.0%, respectively, of the
outstanding shares of Common Stock, which represents approximately 11.2% and
7.7%, respectively, of the total outstanding voting securities. Messrs. Meyers
and Janssen are the principals of the corporate general partner of JMA. If JMA
or its affiliates are deemed to have control of our business, regulatory
requirements of the SEC, Nasdaq and the New York Stock Exchange, Inc. could
prevent JMA from engaging in market-making activities relating to our
securities. If JMA is unable to make a market in our securities because it is
deemed to have effective voting control or if, for any other reason, it chooses
not to or is unable to make a market in our securities, there can be no
assurance that any other broker-dealers would make a market in our securities.
Without market-makers, it would be very difficult for holders of our securities
to sell their securities in the secondary market, and the market prices for such
securities would be substantially harmed. Also, we cannot give any assurances
that an active trading market for our securities be maintained whether or not
JMA makes a market in our securities. In the absence of such a market, investors
may be unable to liquidate their investment. See "-Absence of Public Market;
Possible Volatility of Common Stock and Warrant Prices; and -Selling
Stockholders."

POSSIBLE DELISTING OF OUR SECURITIES FROM THE NASDAQ SMALLCAP MARKET SYSTEM.

         Our Common Stock, Class C Warrants and Class D Warrants are currently
quoted on the Nasdaq SmallCap Market System. Our Common Stock is quoted under
the symbol, "CYPH." Our Class C Warrants are quoted under the symbol, "CYPHW."
Our Class D Warrants are quoted under the symbol, "CYPHZ." Nasdaq has certain
requirements that every company must meet in order to have their securities
first quoted on the Nasdaq SmallCap Market System, and has another set of
requirements that a company must meet to continue to have their securities
quoted on the Nasdaq SmallCap System. Although we currently meet Nasdaq's
criteria for continued listing, we cannot say with any certainty that we will
continue to meet such criteria. For continued inclusion on the Nasdaq SmallCap
Market System, a company has to maintain (i) either (A) net tangible assets of
$2 million, (B) market capitalization of $35 million or (C) net income of
$500,000 in the most recently completed fiscal year or in two of the last three
most recently completed fiscal years; (ii) a minimum bid price of $1.00 per
share; (iii) in the case of a convertible debt security, a principal amount
outstanding of at least $5 million; (iv) in the case of common stock, at least
300 round lot holders and (v) 500,000 publicly held shares having a market value
of at least $1 million. If we are unable to meet the continued listing criteria
of the Nasdaq SmallCap Market System any time in the future due to our continued
operating losses or otherwise, and our securities are delisted, trading, if at
all, of our securities, if any, would be conducted in the over-the-counter
market in the so-called "pink sheets" or, if available, the NASD's "Electronic
Bulletin Board." As a result, investors could find it more difficult to dispose
of, or to obtain accurate quotations as to the value of, our securities. See
"-Our Accumulated Deficit and Loss per Share of Common Stock; Our History of
Significant Losses and Expected Future of Significant Losses; and -Our Need for
Substantial Additional Funds."

RISK OF LOW-PRICED STOCKS; "PENNY STOCK" REGULATIONS.

         If our securities are delisted from the Nasdaq SmallCap Market System,
they may become subject to Rule 15g-9 under the Exchange Act of 1934, which
imposes additional sales practice requirements on broker-dealers that sell such
    

                                       14

<PAGE>   17

   
securities. There are exceptions to Rule 15g-9 and they include transactions
meeting the safe-harbor requirements of Rules 505 or 506 under Regulation D of
the Securities Act, and transactions in which the purchaser is an institutional
accredited investor (as defined in the Securities Act) or an established
customer (as defined in the Securities Act) of the broker-dealer. For
transactions which have to comply with the requirements of Rule 15g-9 under the
Exchange Act of 1934, a broker-dealer must determine whether or not the
purchaser meets a special suitability standard, and the broker-dealer must
receive the purchaser's written consent to the transaction before the sale.
These requirements could make broker-dealers unwilling or even unable to sell
our securities which could make it more difficult for our investors to resell
their securities to other parties. See "-Possible Delisting of Our Securities
from the Nasdaq SmallCap Market System."

         Also, the SEC defines a "penny stock" to be any equity security that
has a market price (as therein defined) under $5.00 per share or has an exercise
price under $5.00 per share, subject to certain exceptions. Unless exempt, the
rules require the delivery, prior to any transaction in a penny stock, of SEC
material telling the purchaser certain information about the penny stock.
Purchasers must also be told about the commissions that the broker-dealers and
the registered representatives will get and they must be told about the
securities current prices. Finally, purchasers must also be given statements
every month which have to tell the purchaser about his or her securities' recent
prices and about the limitations of the penny stock market. These penny stock
restrictions will not apply to our securities if they stay quoted on the Nasdaq
SmallCap Market System, and if they have certain price and volume information
provided on a current and continuing basis or if they meet certain minimum net
tangible assets or average revenue criteria. We cannot say with any certainty,
however, that our securities will continue to meet the Nasdaq SmallCap Market
requirements in the future and if we do not, the prices of our securities could
decrease and investors could find it difficult to sell their securities. Anyway,
even if we remain exempt from the penny-stock restrictions, we still have to
comply with Section 15(b)(6) under the Exchange Act of 1934, which gives the SEC
the authority to stop any person who breaks the law when selling penny stock
from selling any more penny stock or from working with any broker-dealer. See
"-Possible Delisting of Our Securities from the Nasdaq SmallCap Market System;
and -Risk of Low-Priced Stocks; 'Penny Stock' Regulations."

SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS AND DILUTION.

         The market price of our Common Stock, Class C Warrants and Class D
Warrants could drop as a result of a large number of shares of Common Stock in
the market after the offering, or the perceptions that such sales could occur.
These factors also could make it more difficult for us to raise funds through
future offerings of our securities. See "-Possible Delisting of Our Securities
from the Nasdaq SmallCap Market System; and -Risk of Low-Priced Stocks; 'Penny
Stock' Regulations."

         There will be 16,813,453 registered shares of our Common Stock
outstanding upon the completion of this offering. All of these shares will be
freely transferrable without restriction if we continue to comply with the SEC
and certain states' registration requirements. Certain of our other outstanding
securities are not registered with the SEC, and are considered to be,
"restricted securities" as that term is defined in Rule 144 under the Securities
Act and may only be sold in certain circumstances. See "-Possible Delisting of
Our Securities from the Nasdaq SmallCap Market System; and -Risk of Low-Priced
Stocks; 'Penny Stock' Regulations."

         We have also granted certain of our investors who are holding
restricted stock, certain rights to have their Common Stock registered with the
SEC which would lift the selling restrictions of Rule 144 under the Securities
Act. The rights are known as either "demand registration rights" and "piggy-back
registration rights." "Demand registration rights" are rights given to investors
to require us to register their Common Stock at our expense. We have usually
limited how many times investors can exercise these demand registration rights
and have asked for a minimum number of shares of Common Stock before we incur
the expense of registration. "Piggy-back registration rights" are rights given
to investors to ask that we include their Common Stock in any registration
statement we are preparing to file with the SEC. These piggy-back registration
rights can be exercised only if the registration statement is on an appropriate
form; and if it is an underwritten offering, the underwriter of the offering
does not object. The holders of the option granted
    

                                       15

<PAGE>   18


   
during our initial public offering have certain demand registration rights
beginning November 2, 1998 for the shares of Common Stock issuable upon the
exercise of such option Holders of (i) 2,000,000 shares of Common Stock
outstanding, (ii) options to purchase 200,000 shares of Common Stock, (iii)
757,673 shares of Series A Preferred Stock convertible into the same number of
shares of Common Stock and (iv) options to purchase 100,000 shares of Series A
Preferred Stock convertible into the same number of shares of Common Stock (we
will refer to the Common Stock mentioned in (i) through (iv) as the "Registrable
Securities") have demand registration rights and piggy-back registration rights
for Registrable Securities from now until November 7, 2000. The holders of more
than 50% of the Registrable Securities may request that we file a registration
statement under the Securities Act, and, subject to certain conditions, we
generally will be required to use our best efforts to have the SEC declare the
registration statement to be effective. In addition, if we propose to register
any of our securities, either for sale by us or by other investors, we are
required, with certain exceptions, to notify the holders described above and,
subject to certain limitations, to include in the first two such registration
statements filed after December 7, 1996 and before November 7, 2000, all of the
Registrable Securities requested to be included by such holders. In addition, we
have (i) registered our Class A Warrants, Class B Warrants and the 313,088
remaining shares of Common Stock issuable upon the exercise of such warrants
which are outstanding as of April 5, 1999; (ii) registered 150,000 shares of
Common Stock issuable upon the exercise of warrants we had issued to the
placement agent for its services rendered to the us during our private placement
completed in 1992; (iii) registered 1,796,000 shares of Common Stock issuable
upon the exercise of options granted and which we have the right to grant under
our 1992 Stock Option Plan and 1996 Stock Option Plan; (iv) registered 671,026
shares of Common Stock and 335,540 shares of Common Stock issuable upon the
exercise of Class E Warrants we issued in our April 1998 Private Placement,; (v)
134,199 shares of Common Stock and 67,101 shares of Common Stock issuable upon
the exercise of Class E Warrants underlying a unit purchase option granted to
JMA in consideration for its placement agent services in connection with our
April 1998 Private Placement; (vi) granted certain "piggy-back" registration
rights to the holders of 20,000 shares of Common Stock issued by us in
connection with our formation of a joint venture with Pestka Biomedical
Laboratories, Inc.; and (vii) granted the holders of options and warrants to
purchase a total of 175,000 shares of Common Stock certain "piggy-back"
registration rights for providing us with financial advisory and public
relations services rendered to us and pursuant to a license agreement. We will
have to pay for the expense of registration if one or more of these groups
exercise their demand registration rights or "piggy-back" registration rights.
The expense could be high. Also, because there would be a high number of shares
outstanding, we could find it more difficult to obtain future financing. See
"-Possible Delisting of Our Securities from the Nasdaq SmallCap Market System;
- -Risk of Low-Priced Stocks; 'Penny Stock' Regulations; and Description of
Securities."

         The sale, or availability for sale, of substantial amounts of Common
Stock in the public market pursuant to Rule 144 or registration could cause the
market price of the Common Stock and our other securities to decrease which
could hurt our ability to raise additional money through the sale of our
securities or through debt financing. Also, to the extent that outstanding
options and warrants are exercised, investors' ownership interest will drop.
Also, if, and to the extent, that we reduce the exercise price of outstanding
warrants or options, our stockholders could experience additional dilution. See
"-Possible Delisting of Our Securities from the Nasdaq SmallCap Market System;
and -Risk of Low-Priced Stocks; 'Penny Stock' Regulations."

ABSENCE OF PUBLIC MARKET; POSSIBLE VOLATILITY OF COMMON STOCK AND WARRANT
PRICES.

         Our Common Stock, Class C Warrants and Class D Warrants are currently
quoted on the Nasdaq SmallCap Market System. We cannot say with any certainty
that the market for our securities will continue to be active. We are in the
biopharmaceutical industry and the market prices of securities of newly-formed
health care companies have been very unpredictable. Announcements of biological
or medical discoveries or technological innovations by us or our competitors,
developments concerning proprietary rights, including patents and litigation
matters, regulatory developments in both the United States and foreign
countries, public concern as to the safety of new technologies, general market
conditions, quarterly fluctuations in our financial condition and other factors
could cause the market price of our securities to drop.

POTENTIAL ANTI-TAKEOVER EFFECTS.

         Certain provisions of our Certificate of Incorporation could make it
more difficult for a third party to acquire control of our business, even if
such change in control would be beneficial to stockholders. Our Certificate of
Incorporation allows our Board of Directors to issue preferred stock without
stockholder approval. Such issuance could make it more difficult for a third
party to acquire our business. In addition, certain provisions contained in each
of the employment agreements with each of Dr. Arthur P. Bollon, our Chairman,
President and Chief Executive Officer, and Mr. Daniel Shusterman, our Vice
President of Operations, Treasurer and Chief Financial Officer, obligate us to
make certain salary payments if their employment is terminated without just
cause or due to a Disability (as defined therein). See "-Possible Adverse and
Anti-Takeover Effect of Preferred Stock; and Description of Securities."

POSSIBLE ADVERSE AND ANTI-TAKEOVER EFFECTS OF PREFERRED STOCK.

         Our Certificate of Incorporation authorizes our Board of Directors to
issue a maximum of 10,000,000 shares of preferred stock on terms which may be
determined by them without getting stockholder approval. Of these 10,000,000
shares, 4,000,000 shares have already been designated as Series A Preferred
Stock of which 757,673 remain outstanding as of April 5, 1999. The Series A
Preferred Stock are not registered with the SEC or quoted on the Nasdaq SmallCap
Market System or any other exchange. They can, however, be converted by the
holder into an equal number of shares of Common Stock. Also, the terms of the
Series A Preferred Stock include dividend and liquidation preferences which
could also hurt the rights of holders of the Common Stock being offered hereby.
In addition, each share of Series A Preferred Stock is entitled to one vote on
all matters on which the Common Stock has the right to vote. Holders of Series A
Preferred Stock are also entitled to vote as a separate class on any proposed
adverse change in their rights, preferences or privileges and any increase in
the number of authorized shares of Series A Preferred Stock. Further, the terms
of any additional series of preferred stock, which may also include priority
claims to assets and dividends, as well as special voting rights, could hurt the
rights of the holders of the Common Stock being offered hereby. Other than
1,737,791 shares of Series A Preferred Stock, of which 980,118 have been
converted into Common Stock as of April 5, 1999, we have not issued any other
preferred stock, and we do not plan to issue any additional preferred stock
other than payment-in-kind dividends. Since we want to use all of our funds to
continue our various projects but have to pay the holders of the Series A
Preferred Stock a dividend at the end of every fiscal year, we typically choose
to pay them by giving them more shares of Series A Preferred Stock instead of
money.

         Investors should also know that if too much preferred stock is
outstanding, it could make it more difficult for a third party to take control
of our business or to remove our Board of Directors and executive officers.
Hostile bids for control of a company usually result in the market prices for a
company's securities to increase. It would also dilute or subordinate the rights
of holders of Common Stock and cause the market price of the Common Stock to
drop. See "Description of Securities."

CURRENT PROSPECTUS AND STATE REGISTRATION REQUIRED TO RESELL COMMON STOCK.

         The Common Stock in this offering can be resold by the Selling
Stockholders only if a current registration statement relating to them in effect
under the Securities Act and if the Common Stock is qualified for resale or
exempt from qualification under the applicable securities or "blue sky" laws of
the states in which the Selling Stockholders reside. We cannot say with any
certainty that we will be able to meet the SEC and states' registration
requirements. If we cannot meet the requirements, the Selling Stockholders will
be unable to resell their Common Stock. See "Selling Stockholders; Description
of Securities; and Plan of Distribution."

         In addition, the Warrants are subject to redemption by the Company at
$.05 per Warrant, commencing on November 2, 1996, on at least 30 days' prior
written notice if the average closing bid price (or last sales price) of the
Common Stock for 30 consecutive business days ending within 15 business days of
the date on which the notice of redemption is given exceeds $9.10 per share with
respect to the Class C Warrants and $12.25 per share with respect to the Class D
Warrants. If the Warrants are redeemed, holders of Warrants will lose their
right to exercise the Warrants,
    

                                       17

<PAGE>   20

   
except during such 30-day notice of redemption period. Upon the receipt of a
notice of redemption of the Warrants, the holders thereof would be required to:
exercise the Warrants and pay the exercise price at a time when it may be
disadvantageous for them to do so; sell the Warrants at the then market price
(if any) when they might otherwise wish to hold the Warrants; or accept the
redemption price, which is likely to be substantially less than the market value
of the Warrants at the time of redemption. See "Description of Securities --
Class C Warrants and Class D Warrants."


            MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

         The Company's Common Stock, Class C Warrants and Class D Warrants are

                                 DIVIDEND POLICY

   
         The Company has never declared or paid any cash dividends on the Common
Stock. The Company intends for the foreseeable future to reinvest earnings, if
any, to fund the development and expansion of its business. The declaration of
dividends in the future will be at the discretion of the Board of Directors and
will depend upon the earnings, capital requirements and financial position of
the Company, general economic conditions and other pertinent factors. The terms
of the Company's outstanding Series A Preferred Stock do not allow for the
payment of cash dividends on the Common Stock unless and until all accrued and
unpaid dividends on the Series A Preferred Stock shall have been paid or set
apart for payment. The Company paid dividends in cash of $121,491 and in-kind of
shares of Series A Preferred Stock in payment of its 1992 dividend on the Series
A Preferred Stock. For years the fiscal years ended December 31, 1993, 1994,
1995, 1996, 1997 and 1998, the Company also paid in-kind dividends of 104,869,
115,307, 126,888, 122,788, 94,680 and 74,648 shares of Series A Preferred Stock,
respectively, in payment of dividends on the Series A Preferred Stock. The
Company currently intends to retain all earnings, if any, to finance the growth
and development of its business and anticipates that, for the foreseeable
future, that it will continue to pay dividends in-kind on its outstanding Series
A Preferred Stock. See "Plan of Operation" and "Description of Securities."
    

                                    DILUTION

   
         At December 31, 1998, the Company's Common Stock had a net tangible
book value of $5,352,000, or $.52 per share, which represents the amount of the
Company's total tangible assets less liabilities, based on 10,209,844 shares of
Common Stock outstanding. Giving effect to the exercise of outstanding Class C
Warrants, the pro forma net tangible book value of the shares of Common Stock at
December 31, 1998 would have been $1.45 per share, representing an immediate
dilution per share of $5.05 to individuals exercising Class C Warrants. Giving
additional effect to the exercise of the 2,510,927 outstanding Class D Warrants
and the 2,006,073 Class D Warrants issuable upon exercise of the outstanding
Class C Warrants, the pro forma net tangible book value of the shares of Common
Stock at December 31, 1998 would have been $3.30 per share, representing an
immediate dilution per share of $5.45 to individuals exercising Class D Warrants
assuming the prior exercise of all Class C Warrants. Dilution per share
represents the difference between the exercise price and the pro forma net
tangible book value per share after the exercise of the Warrants.

(1)      Assumes the entire exercise price, less expenses of the Offering, is
         allocated to the Common Stock obtained upon exercise.

(2)      Assumes prior exercise of all of the Class C Warrants.



                                 USE OF PROCEEDS

   
         Holders of Warrants are not obligated to exercise their Warrants and
there can be no assurance that such holders will choose to exercise all or any
of their Warrants. Furthermore, the Company is unable to predict the timing, if
ever, of the exercise of any of the above securities, although they are likely
to be exercised at such time as the market price of the Common Stock is
substantially above the exercise price of the Warrants. In the event that all of
the 2,006,073 outstanding Class C Warrants are exercised, the net proceeds to
the Company would be approximately $12,303,000 after deducting the expenses of
the offering and assuming payment of the Solicitation Fee. In the event that all
of the 2,510,927 outstanding Class D Warrants and 2,006,073 Class D Warrants
issuable upon exercise of the outstanding Class C Warrants are exercised, the
Company would receive additional net proceeds of approximately $49,850,000 after
deducting the expenses of the offering and assuming payment of the Solicitation
Fee. The net proceeds received upon the exercise of the Warrants will be used
for research and development and general corporate purposes.

         The foregoing represents the Company's best estimate of the allocation
of the net proceeds received upon exercise of the Class C Warrants and the Class
D Warrants based upon the current status of its business operations, its current
plans and current economic conditions. Future events, including the problems,
delays, expenses and complications frequently encountered by early stage
companies as well as changes in competitive conditions affecting the Company's
business and the success or lack thereof of the Company's marketing efforts, may
make shifts in the allocation of funds necessary or desirable.
    

         Prior to expenditure, the net proceeds will be invested in
high-liquidity, United States government and corporate obligations,
interest-bearing money market funds and other financial instruments.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS



         The Company was organized and commenced operations in September 1991,
and until July 1998, was in the development stage. To this day, the Company's
efforts have been principally devoted to research and development activities and
organizational efforts, including the development of products for the treatment
of cancer and infectious diseases, recruiting its scientific and management
personnel and advisors and raising capital.



         The Company's plan of operation for the next 12 months will consist of
research and development and related activities aimed at:

o        Continued collaboration with Bristol-Myers Squibb on the development of
         Paclitaxel production from Fermentation and Paclitaxel-specific genes.
         See "Business--Research and Development Programs--Paclitaxel
         Fermentation Production System Program."

o        Further development of the Paclitaxel treatment of polycystic kidney
         disease, a potential new Paclitaxel indication, and establishing a
         strategic partnership. See "Business - Research and Development
         Programs - Polycystic Kidney Disease."

o        Development of its rational drug design program using Quantum Core
         Technology(TM). See "Business - Research And Development Programs -
         Quantum Core Technology(TM)."

o        Evaluation of potential new proprietary microbial anticancer drugs with
         Bristol-Meyers Squibb. See "Collaborative Agreements - Bristol-Myers
         Squibb."

o        Further development of a diagnostic test using the patented LCG gene
         and related MAb to test in vitro serum, tissue or respiratory aspirant
         material for the presence of cells which may indicate a predisposition
         to, or early sign of, lung or other cancers. See "Business--Human Gene
         Discovery Program/Lung Cancer Program."

o        Further testing of peptide from UCLA for inhibition of breast cancer
         via steroid receptors. See "Collaborative Agreements - UCLA License
         Agreements."

o        Further analysis of the TNF-PEG technology as an anti-cancer agent in
         animal studies. See "Business--Research and Development Programs--Other
         Programs--TNF-PEG: Broad Range Anticancer Drug Program."

o        Testing proprietary vectors which have been constructed for the
         expression of specific proteins that may be utilizable for vaccines for
         different diseases using Mycobacteria. See "Business -Research and
         Development Programs--Other Programs Vaccine Program."

o        Further development and potential marketing of the anti-sense
         technology currently being conducted at the University of Texas at
         Dallas. See "Business--Research and Development Programs--Other
         Programs--Anti-sense Therapeutics Program."

o        Developing a humanized antibody specific or peptide specific for the

         The actual research and development and related activities of the
Company may vary significantly from current plans depending on numerous factors,
including changes in the costs of such activities from current estimates, the
results of the Company's research and development programs, the results of
clinical studies, the timing of regulatory submissions, technological advances,
determinations as to commercial potential and the status of competitive
products. The focus and direction of the Company's operations will also be
dependent upon the establishment of collaborative arrangements with other
companies, the availability of financing and other factors.

   
         The Company incurred net losses of $2,890,000, $3,252,000 and
$2,728,000 for the twelve months ended December 1996, 1997 and 1998,
respectively. The increase in net losses from 1996 to 1997 was attributable to
decrease in interest income and an increase in general and administrative
expenses. The decrease from 1997 to 1998 was attributable to revenue received
from the Bristol-Myers Squibb License and R&D Agreements and an increase in
interest income, partially offset by an increase in research and development
expenses and general and administrative expenses. The Company expects to incur
additional losses in the foreseeable future.

         The Company incurred general and administrative expenses of $1,530,000,
$1,888,000 and $2,500,000 for the twelve months ended December 1996, 1997 and
1998, respectively. The increase from 1996 to 1997 was attributable to increased
legal and professional fees, as well as, increased consulting fees and travel
expenses. Included in general and administrative expenses for 1997 was a
non-cash charge of $133,000 related to the valuation of stock options issued to
consultants of the Company. The increase from 1997 to 1998 was attributable to
increased legal and professional fees, including increased patent expenses, as
well as, increased insurance costs, increased public relations and financial
relations expenses, partially offset by a decrease in consulting fees and a
decrease in travel and lodging expenses. Included in general and administrative
expenses for 1998 was a non-cash charge of $197,000 related to the valuation of
stock options issued to consultants of the Company.

         The Company incurred research and development expenses of $1,576,000,
$1,469,000 and $1,692,000 for the twelve months ended December 1996, 1997 and
1998, respectively. The decrease from 1996 to 1997 was attributable to the
completion of the Company's funding obligation to RDI partially offset by
increased expenses for contract research and development at Washington State
University and increased rent expenses. The increase from 1997 to 1998 was
attributable to increased funding for the research programs at Washington State
University and Research & Development Institute, Inc., an increase in contract
labor costs and an increase in license fees, partially offset by a decrease in
laboratory supply expenses.

         In April 1998, the Company received net proceeds of approximately
$4,837,000 from the sale of 56 Units consisting of 671,026 shares of Common
Stock and Class E Warrants to purchase 335,540 shares of Common Stock at
exercise prices per share from $9.82 to $11.35, subject to adjustment upon the
occurrence of certain events. During the year ended December 31, 1998, the
Company also received proceeds of approximately $2,630,000 from the exercise of
options and warrants. The Company believes that it has sufficient capital to
finance the Company's plan of operation in excess of 12 months. However, there
can be no assurance that the Company will generate sufficient revenues, if any,
to fund its operations after such period or that any required financings will be
available, through bank borrowings, debt or equity offerings, or otherwise, on
acceptable terms or at all.

GENERAL

   
         Cytoclonal Pharmaceutics Inc., a Delaware corporation ("CPI" or the
"Company"), is a biopharmaceutical company focusing on the development of
diagnostic and therapeutic products for the identification, treatment and
prevention of cancer and infectious diseases. To date, the Company has been
involved solely in research and development activities relating to several
products that are at various stages of development. The Company's research and
development activities relate principally to its proprietary Paclitaxel
Fermentation Production System, its diagnostic and imaging lung cancer products,
Human Gene Discovery Program, Quantum Core Technology(TM) - the Company's
rational drug discovery program and its Vaccine program. Taxol(R) (the brand
name for Paclitaxel) has been designated by the National Cancer Institute as the
most important cancer drug introduced in the past decade.

         The Company's strategy is to focus on its (i) collaboration with
Bristol-Myers Squibb Company, Inc. ("Bristol-Myers Squibb") on the development
of Paclitaxel production from Fermentation and Paclitaxel-specific genes; (ii)
Paclitaxel Fermentation Production System program since Paclitaxel has been
approved by the FDA as a treatment for refractory (treatment resistant) breast
cancer, ovarian cancer, Kaposi's Sarcoma and lung cancer; (iii) Treatment for
Polycystic Kidney Disease using Paclitaxel; (iv) Quantum Core Technology(TM) for
mechanism-based drug design; (v) Human Gene Discovery Program, including a
proprietary cancer related gene ("LCG gene") and related monoclonal antibody
("MAb"), addressing the need for diagnosis and treatment of lung cancer, the
second most common form of cancer; (vi) Vaccine program and (vii) antiestrogen
peptide for breast cancer. Other programs which involve anti-sense therapeutics,
tumor necrosis factor - polyethylene glycol ("TNF-PEG"), fusion protein ("IL-T")
and potential anti-leukemia drug ("IL-P") are being pursued at modest levels.
These other programs may serve as platforms for future products or alternatives
to the primary programs if unforeseen problems develop. In addition, several of
the technologies under development are complementary and could possibly
potentiate each other.

         The Company was created in 1991 to acquire rights to certain
proprietary cancer and viral therapeutic technology ("Wadley Technology")
developed at the Wadley Institutes in Dallas, Texas ("Wadley"). Through its own
research and development efforts and agreements with other research institutions
and biotechnology companies, the Company has acquired and developed additional
proprietary technology and rights. However, to date, the Company has not
developed any commercial products and will require significant additional
financing to complete development and obtain regulatory approvals for its
proposed products which, if ever received, can take several years. See
"-Collaborative Agreements-WadTech."

         In June 1993, the Company received an exclusive worldwide license (the
"RDI Agreement") to use patented fungal technology to synthesize Paclitaxel, the
active ingredient in Taxol(R) (the "Microbial Paclitaxel Technology"), from the
Research & Development Institute, Inc. at Montana State University ("RDI") .
Paclitaxel has proven to be effective in treating refractory ovarian and breast
cancers and, in preliminary clinical trials, has shown potential in treating
refractory non-small cell lung cancer ("NSCLC") and certain other cancer
indications. Presently, Paclitaxel is made from the inner bark and needles of
the slow-growing Pacific yew tree. Scientists at the Company, in cooperation
with the inventors of the microbial paclitaxel technology, are using this
technology and fermentation technology to develop a system for manufacturing
Paclitaxel in commercial quantities and at lower costs than currently available
production methods. In 1994, a patent covering the original fungal strain that
produces Paclitaxel issued. In March 1999, a broad patent issued for the
production of Paclitaxel by utilizing the technology licensed to the Company
pursuant to the RDI Agreement to isolate microorganisms from the slow growing
Pacific yew tree. See "-Research and Development Programs-Paclitaxel
Fermentation Production System Program."

         In February 1996, the Company obtained exclusive rights to a technology
and pending patent developed at the University of California at Los Angeles
("UCLA") for the Paclitaxel treatment of Polycystic Kidney Disease. The patent
issued in 1998. See "-Research and Development Programs-Polycystic Kidney
Disease" and "-Collaborative Agreements-UCLA Agreements."

         In June 1996, the Company entered into a Patent License Agreement (the
"Regents Agreement") with the Board of Regents of the University of Texas System
("Regents") whereby the Company received an exclusive royalty-bearing license to
manufacture, have manufactured, use, sell and sublicense products related to a
U.S. Patent Application entitled "A Method for Ranking Sequences to Select
Target Sequence Zones of Nucleus Acids." The technology has identified optimum
regions within genes to bind anti-sense products. Anti-sense products are under
development to control genes involved in human diseases such as cancer,
diabetes, or AIDS. A patent
    

                                       25

<PAGE>   28

   
application had been filed on this technology and patent was issued in 1999.
This discovery potentially has broad applications to many human and viral genes
involved in human disease. See "-Collaborative Agreements-University of Texas."

         In July 1996, the Company entered into an agreement (the "WSURF
Agreement") with the Washington State University Research Foundation ("WSURF")
whereby the Company received an exclusive, world-wide license to use and/or
sublicense patented technology or prospective patented technology (the "WSURF
Technology") related to genes and the associated gene products, including the
enzymes, in the biosynthetic pathway for Paclitaxel from the yew tree. The genes
will be used to further optimize the Paclitaxel Production System. See
"-Collaborative Agreement-WSURF."

         In June 1998, the Company entered into a Master License Agreement (the
"BMS License Agreement") and a Sponsored Research Agreement (the "R&D
Agreement") with Bristol-Myers Squibb. Pursuant to the BMS License Agreement,
the Company granted to Bristol-Myers Squibb an exclusive sublicense under each
of the (i) the RDI Agreement (the "BMS-RDI Sublicense Agreement") and (ii) the
WSURF Agreement. The R&D Agreement contemplates a program directed toward
developing microbial fermentation and genetic engineering technologies for the
production of Paclitaxel and other taxanes. See "-Collaborative
Agreement-Bristol-Myers Squibb."

         In August 1998, the Company obtained exclusive world-wide rights to a
technology and pending patent developed at UCLA for a peptide antiestrogen
breast cancer therapy for a term of the life of the patent, subject to
termination in certain circumstances.

         In December 1998, the Company obtained an exclusive license to
technology for the fungal production of Telomerase, the so-called "immortality
enzyme," from RDI.

         Effective January 4, 1999, the Company acquired proprietary technology
for rational based drug design developed by Dorit Arad, Ph.D. and employed Dr.
Arad as Vice President of Drug Design.
    

         The Company was originally incorporated in the state of Texas in
September 1991 as Bio Pharmaceutics, Inc. In November 1991, the Company changed
its name to Cytoclonal Pharmaceutics Inc. The Company was reincorporated in
Delaware by merger into a wholly-owned Delaware subsidiary in January 1992.



RESEARCH AND DEVELOPMENT PROGRAMS

   
         MICROBIAL PACLITAXEL PRODUCTION SYSTEM PROGRAM

         Scientists at the Company in collaboration with the inventors of the
microbial Paclitaxel technology (the "Microbial Paclitaxel Technology"), have
developed a system for the production of Paclitaxel (the "Paclitaxel
Fermentation Production System") utilizing microbial fermentation. Microbial
fermentation is considered one of the most cost effective systems for drug
production. The Company has established agreements with Bristol-Myers Squibb to
develop microbial fermentation for the commercial production of Paclitaxel.

         Presently, Paclitaxel is made from the inner bark and needles of the
slow-growing Pacific yew tree. Supplies of Paclitaxel are limited and expensive.
The Microbial Paclitaxel Technology licensed by RDI to the Company pursuant to
the RDI Agreement utilizes Paclitaxel producing micro-organisms, such as the
fungus Taxomyces andreanae. This fungus was initially isolated from a Pacific
yew tree and has been adapted to grow independently from the yew tree utilizing
fermentation processes. Detailed chemical analysis of the Paclitaxel produced by
the fungus indicates chemical equivalency to Taxol(R) produced from the Pacific
yew tree; Science, 260, 214-216 (1993). Additional micro-organisms have been
isolated and are under development.

         The Paclitaxel producing fungus was discovered by Dr. Gary Strobel from
Montana State University ("MSU"), Dr. Andrea Stierle from MSU and Montana
College of Mineral Science and Technology ("MCMST") and Dr. Donald Stierle of
MCMST. Dr. Stierle and Dr. Strobel assigned their rights to the Microbial
Paclitaxel Technology to RDI, a non-profit corporation which manages
intellectual property for MSU and MCMST. RDI was issued a U.S. patent on the
Microbial Paclitaxel Technology on June 21, 1994 covering the method of
isolating the fungus which produces Paclitaxel, the use of the fungus to make
Paclitaxel, and the method of producing Paclitaxel from the fungus. In June
1993, RDI and the Company entered into the RDI Agreement whereby RDI granted the
Company worldwide exclusive rights to the Microbial Paclitaxel Technology and
technologies related thereto. It has been reported that over ten companies,
including several major pharmaceutical companies, were competing to license this
technology. In March 1999, a broad patent issued for the production of
Paclitaxel by microorganisms isolated from the slow growing Pacific yew tree
utilizing the technology licensed to the
    

                                       26

<PAGE>   29

   
Company pursuant to the RDI Agreement. The Company believes that the experience
of Dr. Arthur P. Bollon, the Company's Chairman, President and Chief Executive
Officer, in the area of fungi, which originated from his Post-Doctoral
Fellowship at Yale University, combined with the research and development
activities of the Company in anti-cancer products, contributed to the Company
obtaining the Microbial Paclitaxel Technology. See "-Collaborative
Agreements-RDI" and "Management."

         The Paclitaxel Fermentation Production System also produces certain
compounds called Taxanes which can be precursors to Paclitaxel or related
compounds like Taxotere. These compounds are under investigation by several
entities, including Rhone-Poulenc Rorer Pharmaceuticals, Inc., which is using
Taxotere as a therapeutic for use in the treatment of lung cancer.

         Development efforts are continuing with respect to the Paclitaxel
Fermentation Production System with the goal of generating commercial quantities
of Paclitaxel at reduced costs. Scientists at the Company, in conjunction with
the inventors of the Microbial Paclitaxel Technology, have increased the level
of Paclitaxel production over 3,000 fold from the initial levels of production
under the Paclitaxel Fermentation Production System. Media, growth conditions
and strain improvements continue to be used to improve the Paclitaxel
Fermentation Production System. The Company's participation in this development
program is under the direction of Dr. Rajinder Sidhu, Director of the Company's
Fungal Paclitaxel Program, and Dr. Bollon.

         Furthermore, in July 1996, the Company and WSURF entered into the WSURF
Agreement therein WSURF granted the Company the exclusive rights to a gene
isolated from the Yew tree by Dr. Rodney Croteau. The gene codes for the enzyme
Taxadiene Synthase which is involved in a critical step for Paclitaxel
production and the gene and other paclitaxel genes isolated by Dr. Croteau are
expected to be utilized to further increase the efficiency of Paclitaxel
synthesis by fermentation. Manipulation of genes by genetic engineering have
greatly improved production of pharmaceutical products such as antibiotics and
human interferon and insulin.

         The NCI has recognized Taxol(R) as one of the most important cancer
drugs discovered in the past decade. Paclitaxel, although not a cure for cancer,
promotes the assembly of cellular microtubules to render fast growing cells,
such as cancer cells, unable to divide and proliferate. This mode of action is
in contrast to most cancer drugs which target the cell nucleus or DNA.
Paclitaxel has proven to be effective in treating refractory
(treatment-resistant) ovarian and breast cancers, and forms of lung cancer and
certain other cancers. Due to its different mode of action, Paclitaxel is being
tested in combination therapy with other cancer therapeutic drugs.

         Evidence to date has shown that Paclitaxel is generally well tolerated
by patients with reduced side effects compared to other chemotherapy treatments.
Considering that no currently available anti-cancer agents are free from
toxicity, Paclitaxel's comparatively safety profile suggests substantial
improvements in quality of life for patients who must undergo chemotherapy.
Nevertheless, hypersensitivity reactions and other side effects have been noted
during Paclitaxel administration. Reactions are characterized by transient
hypotension and an allergic type response, which appear to cease upon stopping
drug administration. Premedication effectively minimizes or eliminates this
problem, although side effects may nevertheless limit some patients' use of
Paclitaxel. In addition, Paclitaxel has been shown to produce peripheral
neuropathy (loss of sensation or pain and tingling in the extremities) and
neutropenia (low white blood cell counts), which also may, in certain cases,
limit some patients' use of Paclitaxel.

         In June 1991, the NCI formalized a Collaborative Research and
Development Agreement ("CRADA") for development of Taxol(R) with Bristol-Myers
Squibb as its pharmaceutical manufacturing and marketing partner. This CRADA had
granted Bristol-Myers Squibb the exclusive use, until December 1997, of NCI's
clinical data relating to Paclitaxel in seeking approval from the FDA, which
significantly shortened the approval process and prevented any other party from
obtaining FDA approval using the NCI data. Although Bristol-Myers Squibb has
since lost its right of exclusivity under the CRADA, effective Paclitaxel
exclusivity is still being maintained by Bristol-Myers Squibb due to a patent on
its Taxol(R) infusion method, that exclusivity currently being contested by
other competitors in the courts. Bristol-Myers Squibb received FDA approval for
the commercial sale of its Taxol(R) as a treatment for refractory ovarian cancer
in December 1992, refractory breast cancer in April 1994 and Kaposi's Sarcoma in
August 1997. In 1998, Bristol-Myers Squibb received approval for Taxol(R)
treatment of lung cancer. Since December 1992, Bristol-Myers Squibb has been the
sole source of Taxol(R) for commercial purposes. It is the Company's
understanding that Bristol-Myers Squibb is currently conducting clinical trials
required for FDA approval of Taxol(R) for treating other cancers. See
"-Competition."
    

         Alternative production systems for Paclitaxel, such as plant cell
culture, complete synthesis and improved processing of yew tree material, are
under investigation by others and there can be no assurance that such
alternative methods will not be developed prior to the Company's proposed method
or that they will not prove more efficient and cost effective than the method
being developed by the Company.

         POLYCYSTIC KIDNEY DISEASE

         In February 1996, the Company entered into two license agreements with
the Regents of UCLA therein granting the Company exclusive rights to: (i) a
pending patent, entitled "Inhibition of Cyst Formation By Cytoskeletal Specific
Drugs" that makes use of various drugs, one of which is Paclitaxel and (ii)
technology in the field of Pharmacological Treatment for Polycystic Kidney
Disease. See "-Collaborative Agreements-UCLA."

         Approximately 500,000 individuals in the U.S. and 5 million individuals
world-wide are afflicted with Polycystic Kidney Disease ("PKD"). There is no
treatment except management by dialysis or transplantations. Dr. David Woo of
UCLA has shown in an animal model system that Taxol(R) inhibits cyst
enlargement, resulting in increased survival of treated animals. The Company, in
collaboration with Dr. Woo, is attempting to develop, although there can be no
assurance of successful completion, if any, this potential new use of Taxol(R).
There can be no assurance that the Company will be able to perform human
clinical studies for Taxol(R) treatment or, if performed, such studies will be
successful. Also, a patent for treatment of PKD by Taxanes, such as Paclitaxel,
issued in 1998. The Company is currently in negotiations with potential
strategic partners for Paclitaxel treatment of PKD. However, there can be no
assurances that such negotiations will be successful. See "-Collaborative
Agreements-UCLA."



         QUANTUM CORE TECHNOLOGY(TM)

         In connection with the Company's employment of Dorit Arad, Ph.D. as
Vice President of Drug Design in January 1999, the Company acquired rights to
certain proprietary molecular scaffolds and technology for the mechanism-based
design of novel protease inhibitors as well as certain anti-cancer and
anti-viral agents developed by Dr. Arad at Tel Aviv University in Tel Aviv,
Israel. The design of mechanism-based protease regulators is built upon an
understanding of the target structure and chemical mechanism. Unlike
structure-based rational drug design and combinatorial chemistry where large
numbers of molecules based upon known substrate structure, with non-selective
chemistry, may be screened for high affinity binding and/or activity, the
Company begins with an "active" core or scaffold of low molecular weight known
to be mechanism specific. Affinity maturation to optimize enzyme binding
(selectivity) is then achieved by standard combinatorial chemistry approaches.
Through its own proposed research and development efforts as well as through
potential future collaborative agreements with research institutions and other
pharmaceutical companies, the Company anticipates, although there can be no
assurance, developing additional proprietary technology to serve as the basis
for the eventual introduction of commercial products. Commercial development of
these products will require significant additional financing for completion of
development, clinical studies and obtainment of regulatory approvals. See
"Management."
    


         HUMAN GENE DISCOVERY PROGRAM/LUNG CANCER PROGRAM

         The Company's Human Gene Discovery Program focuses on identifying and
isolating human genes by utilizing biological markers employing MAbs and
analyzing cellular activities associated with the cause or treatment of various
diseases. Genes play an important role in the development of a variety of
therapeutics, diagnostics and other products and services. Proteins expressed by
genes are the targets of many drugs. As a result, the identification of proteins
can play an important role in the development of drugs and drug screens. The
identification of genes that code for proteins that may be missing or defective
can enable the development of therapeutics for genetic diseases. In addition,
identification of genes that may predispose a person to a particular disease may
enable the development of diagnostic tests for the disease.

   
         One of the central features of the Company's Human Gene Discovery
Program is its proprietary human gene expression libraries and its
RetroselectionTM approach to isolating human genes with a defined function.
Currently, these libraries consist of over 50,000 human gene clones isolated by
the Company through extracting expressed messenger RNA from human tissue and
cells in different development stages and in normal and diseased states. By
comparing the genes expressed from tissue in different physiological states
(e.g., diseased and normal), the Company hopes to identify genes that are
expressed during different stages of a disease and that could serve as
components of diagnostic tests or as targets for therapeutic drugs. Thus, the
Company's Human Gene Discovery Program concentrates on gene products with
associated biological or medical use as opposed to only DNA sequences. At
present, the Company is focusing on creating MAb and DNA probes products for
diagnostic and imaging applications.
    

                                       28

<PAGE>   31

   
         The Company is developing a proprietary MAb (the "LCG MAb") which
recognizes a specific protein (the "LCG protein") on the surface of some lung
cancer cells, such as NSCLC, which is believed to represent approximately 65% of
lung cancers. In addition, the cancer related human gene ("LCG gene") that makes
this surface protein, has been isolated by the Company's scientists by a process
the Company calls "Retroselection." The specificity of the LCG protein to some
lung cancers is based on studies on biopsy material, biodistribution studies on
animal model systems and Phase I clinical trials. A U.S. patent for the LCG
gene, filed by the Company in July 1994, was issued on December 31, 1996. A
patent for the lung cancer gene marker issued in June 1998.

         The LCG gene and LCG MAb are being developed by the Company as a
potential diagnostic product to test in vitro serum, tissue or respiratory
aspirant material for presence of cells which may indicate a predisposition or
early sign of lung cancer. The LCG MAb is also being developed as an in vivo
imaging agent for lung cancer. An imaging agent may assist physicians in
establishing the location of a cancer and determine whether the cancer has
spread to other sites in the body. In Phase I human clinical trials performed at
Wadley, the LCG MAb made from mouse cells and labeled with a radioactive marker
showed strong specificity in 5 of 6 patients. In these trials, the LCG MAb bound
to the lung cancer but was not detectable for normal lung cells. These clinical
studies will be expanded with a human-related form of the LCG MAb which is
presently under development by the Company. Working with cells in culture, the
Company is studying whether the LCG gene itself may be potentially useful as a
genetic probe to test for the presence of the LCG gene expression where the LCG
protein has not been made or has been made at low levels.

         Additional potential products under development using the LCG gene and
LCG MAb are products for the delivery of therapeutic drugs, such as Paclitaxel
and TNF-PEG, to the cancer. The involvement of the LCG gene in the formation and
metabolism of the lung cancer is also under investigation. In addition, the LCG
protein could possibly be used as an antigen for a vaccine against NSCLC. The
Company has deferred plans to initiate testing in animal model systems and
conducting clinical trials since successful development of vaccine applications
will take significant additional research and development efforts and
expenditures.

         The Human Gene Discovery Program is also being used to isolate
additional novel cancer related genes utilizing specific MAbs for breast and
ovarian cancer and melanoma which are proprietary to the Company. A U.S. patent
for the melanoma MAb was issued to WadTech and assigned to the Company. A U.S.
patent for a melanoma antigen issued to the Company in August, 1997. See
"-Collaborative Agreements-WadTech."

         The Human Gene Discovery Program is conducted under the direction of
Dr. Richard Torczynski, along with Dr. Bollon. Dr. Torczynski and Dr. Bollon
have extensive experience isolating human genes including IFN-WA, a novel
interferon, and the LCG gene. The human-related form of the LCG MAb is under the
direction of Dr. Susan Berent.



         OTHER PROGRAMS

         In addition to its Paclitaxel Fermentation Production System Program,
Paclitaxel treatment of Polycystic Kidney Disease and Human Gene Discovery
Program/Lung Cancer Program, the Company is pursuing other programs at modest
levels which may serve as platforms for the development of future products or
alternatives to such primary programs. These include the (i) Vaccine Program,
(ii) Anti-sense Therapeutics Program, (iii) TNF-PEG: Broad Range Anti-cancer
Drug Program, (iv) IL-T: Prevention of Radiation and Chemotherapy Damage Program
and (v) IL-P Anti-leukemic Product Program.

         Vaccine Program. The main objective of the Company's vaccine program is
to develop genetically engineered live vaccines for diseases that are life
threatening. The Company's current strategy consists of (i) identifying
bacterial host strains that are best suited for delivering recombinant
immunogens and cancer markers; (ii) developing proprietary cloning and
expression vectors that can transfer, maintain and express recombinant
immunogens and cancer markers in the delivery system; and (iii) cloning genes
for specific immunogens or cancer markers into the vectors and testing the
vaccine system in appropriate animal models and, if successful, commencing
clinical trials.

         The Company has identified three host strains of mycobacteria that
appear well suited for expressing and delivering protein and lipid antigens.
Furthermore, the Company has constructed plasmid and phage-based cloning vectors
and developed reproducible transformation techniques for the host strains. These
vectors have large cloning capacities and are highly efficient in
transformation. Potential antigens for cancer markers are the proprietary LCG
gene and other cancer genes for breast cancer and melanoma which are under
development by the Company. The Company's goal is to license, as licensor and
licensee, new cancer specific marker genes and
    

                                       29

to enter into strategic partnerships to develop vaccines for infectious
diseases, such as tuberculosis.

         These vaccine studies are under the direction of Dr. Labidi, who is
director of the Company's vaccine program. Dr. Labidi, who received his Ph.D. in
Microbiology from the Pasteur Institute, in Paris, France, was one of the early
investigators to establish the plasmid profile of several mycobacterium species
and was the first to isolate, characterize and sequence the mycobacterium
plasmid pAL5000 which has contributed to mycobacterium cloning and expression
vectors. Working with the Company and Dr. Labidi is Dr. Hugo David, a consultant
to the Company and a member of its Scientific Advisory Board. Dr. David was
formerly the head of the tuberculosis program at the Center for Disease Control
(CDC) in the U..S. and at the Pasteur Institute.

         Anti-sense Therapeutics Program. Anti-sense has the potential of
regulating genes involved in various disease states. The Company is sponsoring
anti-sense research and development under the direction of Dr. Gray, Professor
of Molecular and Cell Biology at University of Texas at Dallas. The Company had
a right of first refusal for an exclusive worldwide license for the technology
developed in connection with these research activities, which rights the Company
exercised in June 1996 and has obtained an exclusive world-wide license for
certain anti-sense technology developed by Dr. Gray. Pursuant to this program,
Dr. Gray has developed, and a patent application had been submitted and a patent
issued in 1999 therein covering proprietary technology which may improve the
efficiency of anti-sense reagents potentially applicable to a broad spectrum of
diseases. The capability has recently been computerized, which will be contained
in a related patent continuation-in-part. See "-Collaborative
Agreements-University of Texas."

         TNF-PEG: Broad Range Anti-cancer Drug Program. TNF is a natural immune
protein (cytokine) made by human cells. It has been found to kill in vitro a
high percentage of different cancer cells compared to normal cells and is one of
the most potent anti-cancer agents tested in animals. The Company has TNF
technology, including TNF analogs, which the Company believes are proprietary
and which were developed at Wadley utilizing a genetically engineered bacteria
and developed further by Lymphokine Partners Limited, a partnership set up by an
affiliate of Wadley and Phillips Petroleum Company (the "Wadley/Phillips
Partnership"). The Company acquired this technology from Wadley Technologies,
Inc. ("WadTech"). Phase I and II human clinical trials were performed at Wadley
using 23 patients with different kinds of cancer. These studies, as well as
studies on TNF technology developed by others, showed no therapeutic benefit
from TNF in humans because of the high toxicity of TNF at therapeutic doses and
its relatively short half life (approximately 30 minutes) at lower doses. See
"-Collaborative Agreements-WadTech."

         Pursuant to a research collaboration (the "Enzon Agreement") with
Enzon, Inc. ("Enzon"), the Company and Enzon are developing an anti-cancer agent
combining the Company's TNF technology with Enzon's patented polyethylene glycol
("PEG") technology. The PEG process involves chemically attaching PEG, a
relatively non-reactive and non-toxic polymer, to proteins and certain other
biopharmaceuticals for the purpose of enhancing their therapeutic value.
Attachment of PEG helps to disguise the proteins and to reduce their recognition
by the immune system, thereby generally lowering potential immunogenicity. Both
the increased molecular size and lower immunogenicity result in extended
circulating blood life, in some cases from minutes to days. The PEG technology
is a proven technology covered by patents held by Enzon. To the Company's
knowledge, Enzon has two products on the market using PEG, PEG-adenosine
deaminase, for treatment of the immune deficiency disease know as the "bubble
boy" syndrome, and PEG-Asparaginase, a cancer chemotherapeutic drug. In
preliminary animal studies at Sloan-Kettering Institute for Cancer Research
("Sloan-Kettering"), a TNF-PEG construct has been tested in an animal cancer
model system and was shown to kill tumors with possibly reduced toxicity. The
results of these studies will be confirmed and expanded and, if the TNF-PEG does
result in longer half life and reduced toxicity, an investigational new drug
("IND") application for clinical trials is expected to be submitted by the
Company or Enzon. There can, however, be no assurance that similar results will
be found in humans. The Enzon Agreement also involves directing TNF-PEG to human
cancers using Enzon's proprietary single chain antibodies. See "-Collaborative
Agreements-Enzon" and "Collaborative Agreements-Sloan Kettering."

         The Enzon Agreement involves equal sharing of revenue from sales of
TNF-PEG if both parties contribute equally to its development, which is the
Company's intention. There can, however, be no assurance that the Company will
have the financial resources to meet such obligations. The Enzon Agreement also
specifies that Enzon will work with only the Company on the construction of
TNF-PEG, unless the Company consents to Enzon working with a third party. See
"-Collaborative Agreements-Enzon."

         IL-T: Prevention of Radiation and Chemotherapy Damage Program. This
program involves a novel protein called IL-T. The Company and the
Wadley/Phillips Partnership constructed IL-T through genetic engineering by
fusing together parts of two human immune proteins ("cytokines"), Interleukin
and TNF. The Company is testing various combinations of cytokines for improved
protection against radiation and chemotherapy damage. The IL-T protein has been
tested in animal studies for protection against radiation damage at
Sloan-Kettering and these studies are expected to continue. Following animal
studies confirmation of protection against radiation
    

                                       30

damage could potentially lead to filing an IND application with the FDA followed
by Phase I clinical trials. Products proprietary to others have shown protection
against radiation damage and to potentiate weakened immune cells. The Company
has filed a patent application for IL-T. See "-Collaborative Agreements-WadTech"
and "-Collaborative Agreements-Sloan-Kettering."

         IL-P Anti-Leukemic Product Program. Through its joint venture with
Pestka Biomedical Laboratories, Inc. ("Pestka"), the Company is participating in
the development of a novel anti-leukemic drug known as ("IL-P"). This research
and development involves the application of certain phosphorylation technology
developed at Pestka and licensed to the joint venture to Interleukin-2. Various
constructs of IL-P have been tested at Pestka and the Company expects to provide
additional funding to the joint venture for the continuation of such tests. See
"-Collaborative Agreements-Cytomune."

         For the fiscal years ended December 31, 1998 and 1997, the Company
incurred $1,692,000 and $1,469,000 of research and development expenses,
respectively. See "Management's Discussion and Analysis of Financial Condition"
and "Financial Statements."



COLLABORATIVE AGREEMENTS

         BRISTOL-MYERS SQUIBB

         In June 1998, the Company entered into the BMS License Agreement and

         WADTECH

   
         In October 1991, the Company entered into a purchase agreement with
WadTech (the "WadTech Agreement"), whereby the Company acquired certain of
WadTech's right, title and interest in and to the Wadley Technology, including
technology developed by Wadley, and acquired by WadTech upon dissolution of the
Wadley/Phillips Partnership and licensed to WadTech by Phillips Petroleum
Company ("Phillips"). The Wadley Technology includes, but is not limited to,
technology related to TNF, IL-T, a novel interferon designated IFN-WA, and
select melanoma, ovarian, breast, colon and lung cancer MAbs. See "-Research and
Development Programs-Human Gene Discovery Program/Lung Cancer Program" and
"-Other Programs-TNF/PEG: Broad Anti-cancer Drug Program."

         Pursuant to the WadTech Agreement, the Company has agreed to (i) pay
WadTech the sum of $1,250,000 (the "Fixed Sum"), (ii) pay WadTech royalties on
sales of products incorporating the Wadley Technology and a percentage of all
royalties and other consideration paid to the Company by any licensees of the
Wadley Technology, all of which are to be applied toward the Fixed Sum, (iii)
assume WadTech's obligations under a license agreement entered into in March
1989 between the Wadley/Phillips Partnership and Phillips (the "Phillips
Agreement"), namely the obligation to pay royalties of up to 3.75% on sales
products produced using Phillips recombinant yeast expression system, and (iv)
pay to WadTech minimum annual royalties of $31,250 for the year beginning
October 1, 1996, $62,500 for the year beginning October 1, 1997 and $125,000 for
each year thereafter. The WadTech Agreement provides that the royalties and
other sums payable by the Company to WadTech are at a higher rate until the
Fixed Sum has been paid in full. The term of the WadTech Agreement is for 99
years but may be terminated earlier by WadTech if the Company fails to cure a
default in its payment obligations or breaches any material term or condition of
the agreement. See "-Research and Development Programs-Human Gene Discovery
Program/Lung Cancer Program" and "-Other Programs-TNF/PEG: Broad Anti-cancer
Drug Program."
    

         In order to secure the Company's obligation to pay the Fixed Sum to
WadTech, the Company and WadTech entered into a Security Agreement (the
"Security Agreement"), pursuant to which WadTech retains a security interest in
all of the Wadley Technology until the Fixed Sum is paid in full to WadTech. The
Security Agreement also provides that in the event of a default (which includes
failure of the Company to perform any material obligation under the WadTech
Agreement), WadTech would have the right to license the Wadley Technology to a
third party or sell the Wadley Technology through a foreclosure sale.



         RDI

   
         In June 1993, the Company entered the RDI Agreement with RDI, a
non-profit entity which manages the intellectual property of MSU and MCMST,
therein granting to the Company worldwide exclusive rights to the Microbial
Paclitaxel Technology. Pursuant to the RDI Agreement, the Company made an
initial payment of $150,000 to RDI and has agreed to pay RDI royalties on sales
of products using the Microbial Paclitaxel Technology and a percentage of
royalties paid to the Company by sublicensees of the Microbial Paclitaxel
Technology, and has paid RDI $25,000 in June 1994, $50,000 in June 1995, $75,000
in June 1996, $100,000 in June 1997 and $100,000 in June 1998, and has agreed to
pay RDI $100,000 each year thereafter that the license is retained. The Company
in 1994 also granted to RDI stock options to purchase up to 20,000 shares of the
Company's Common Stock at $2.50 per share exercisable over four years, all of
which are currently exercisable. The Company and RDI also entered into a
Research and Development Agreement (the "Paclitaxel R&D Agreement") effective
the date of the RDI Agreement. The Paclitaxel R&D Agreement provides for RDI to
perform research and development at MSU relating to the Paclitaxel Fermentation
Production System. Pursuant to the Paclitaxel R&D Agreement, the Company has
agreed to make payments of $250,000 per year for four years. In 1998, the
Company and RDI agreed to a one year renewable extension of the Paclitaxel R&D
Agreement. The Company has, to date, paid a total of $1,637,000 under both RDI
agreements. In February 1995, the Company and RDI amended the RDI Agreement and
Paclitaxel R&D Agreement to include technology applicable to commercial
products, in addition to Paclitaxel and Paclitaxel related technology,
identified and developed from organisms/products supplied to RDI by Dr. Gary
Strobel, Dr. Andrea Stierle and/or Dr. Donald Stierle pursuant to the RDI
Agreement and Paclitaxel R&D Agreement. These additional technologies could
include, but are not limited to, anti-cancer, anti-viral, anti-fungal or any
other activities which could result in any commercial products. In May 1998, the
Company and RDI amended the RDI Agreement therein requiring the Company to pay
to RDI (i) a percentage of royalties received with respect to the manufacture,
use or sale of the inventions by sublicensees, which royalty rate shall be
reduced in the event the Company is required to pay royalties to others and (ii)
all up-front, milestone and royalty payments it may receive pursuant to certain
provisions of the BMS-RDI Sublicense Agreement. See "General" and
"-Collaborative Agreements-Bristol Myers Squibb."

<PAGE>   35


   
         In February 1995, the Company entered into a license agreement (the
"FTS-2 License Agreement") with RDI, therein granting the Company worldwide
exclusive rights to exercise all intellectual property rights relating to a
fungal strain identified as "FTS-2" (the "FTS-2 Rights") which contains a
cytotoxic activity for a breast cancer line and related activities. In October
1995, the Company entered into a license agreement (the "Tbp-5 License
Agreement") with RDI, granting to the Company worldwide exclusive rights to
exercise all intellectual property rights relating to a fungal strain identified
as "Tbp-5" (the "Tbp-5 Rights" and together with the FTS-2 Rights, the
"Intellectual Property Rights") which contains a cytotoxic activity for a breast
cancer cell line. Pursuant to the FTS-2 License Agreement and the Tbp-5 License
Agreement, the Company has agreed to pay RDI royalties on sales of products or
services using the Intellectual Property Rights and a percentage of royalties
paid to the Company by sublicensees using the Intellectual Property Rights. See
"-Collaborative Agreements-Bristol Myers Squibb."

         In December 1998, the Company obtained an exclusive license to
technology for the fungal production of Telomerase, the so-called "immortality
enzyme," from RDI.

         In March 1999, a broad patent issued for the production of Paclitaxel
by microorganisms isolated from the slow growing Pacific yew tree utilizing the
technology licensed to the Company pursuant to the RDI Agreement.
    


         UCLA LICENSE AGREEMENTS

   
         In February 1996, the Company entered into two license agreements with
the Regents of UCLA, therein granting the Company exclusive rights to: (1) a
pending patent, entitled, "Inhibition of Cyst Formation By Cytoskeletal Specific
Drugs" ("UCLA License Agreement I") that makes use of various drugs, one of
which is Paclitaxel and (2) technology in the field of Pharmacological Treatment
for PKD ("UCLA License Agreement II"). Pursuant to UCLA License Agreement I, the
Company paid a license issue fee of $5,000 and has agreed to pay UCLA $10,000
upon issuance of a patent. Pursuant to the UCLA License Agreement II, the
Company paid a license issue fee of $5,000 and has agreed to pay UCLA $5,000
upon issuance of a patent. The Company must pay a yearly license maintenance fee
on both licenses until the Company is commercially selling a product based on
the technology derived from UCLA License Agreement I and UCLA License Agreement
II, at which time a royalty based on net sales will be due.


         In August 1998, the Company entered into an exclusive world-wide
license agreement with UCLA ("UCLA Agreement III") for any domestic and foreign
patents and patents pending based upon and including any subject matter claimed
in or covered by a U.S. patent pending entitled, "Peptide Antiestrogen
Compositions and Methods for Treating Breast Cancer," (collectively, the "Patent
Rights"). The UCLA Agreement III grants the Company the right to make, use,
sell, offer for sale and import certain products involving the Patent Rights
(collectively, the "Patent Products") and to conduct any process or method
covered by the Patent Rights (the "Patent Methods"). Also, the Company may grant
sublicenses to third parties to make, use, sell, offer for sale and import
Patent Products and to practice Patent Methods where Patent Rights exist,
provided the Company retains exclusive rights thereto under the UCLA Agreement
III. The UCLA Agreement III requires the Company to pay up-front fees, fees upon
the issuance of a patent application under the Patent Rights, maintenance fees,
annual and quarterly royalty payments, and milestone payments. The term of the
UCLA Agreement III commenced August 1998 and ends upon the termination or
cancellation of the last patent covered by the Patent Rights, subject to earlier
termination by the Regents if the Company's fails to perform certain studies and
clinical trials by certain dates or cure any breaches within 60 days notice from
the Regents.
    


         ENZON

   
         In July 1992, the Company and Enzon entered into the Enzon Agreement
providing for the conduct of a collaborative research and development program to
develop an anti-cancer agent by combining the Company's TNF technology with
Enzon's PEG technology. Pursuant to this agreement, each party agreed to fund
its own development costs associated with the initial stage, roughly the first
year, of the program. The agreement provides that if both parties agree to
continue the TNF-PEG program jointly, each party shall share equally in the cost
of such research and development and the profits therefrom. If one party decides
not to proceed or is unable to share jointly, the continuing party will receive
exclusive (even as to the other party) worldwide licenses in the applicable
technology of the other party and will pay the other party royalties. The term
of the Enzon Agreement is 15 years for each product developed under the program
from the date of FDA approval to market such product. The Company and Enzon also
entered into a similar agreement in March 1992 relating
    

                                       33
<PAGE>   36

   
to combining various target proteins to be developed by the Company with Enzon's
PEG-technology pursuant to which Enzon funded certain of the Company's initial
research and development activities thereunder. To the extent this earlier
agreement applied to TNF, it was superseded by the Enzon Agreement. Currently,
the primary focus of the parties is on the Enzon Agreement and the TNF-PEG
technology.
    


         SLOAN-KETTERING

   
         Pursuant to a Research Agreement, effective April 8, 1994, between the
Company and the Sloan-Kettering, Sloan-Kettering has agreed to continue
evaluating the IL-T fusion protein to determine whether such protein protects
mice against radiation and chemotherapy. In connection with such activities,
Sloan-Kettering has agreed to provide all necessary personnel, equipment
supplies and facilities in completion of the protocol set forth in the agreement
for a budget not to exceed $35,000. Inventions resulting from Sloan-Kettering's
research which were not contemplated by the parties, if any, will be the
property of Sloan-Kettering. However, Sloan-Kettering must grant the Company the
right of first refusal to acquire a world-wide exclusive license to develop and
commercialize any such invention upon mutually agreeable terms. The term of the
agreement is through completion of the protocol.
    



         CYTOMUNE

   
         Cytomune, Inc. ("Cytomune") is a joint venture (50:50) between the
Company and Pestka. A novel anti-leukemic drug, IL-P, is in development
utilizing proprietary technology developed by Dr. Sidney Pestka. Dr. Pestka
developed interferon for commercial use for Hoffmann-La Roche, Inc. The
objective of the joint venture is to develop IL-P for the diagnosis and
treatment of leukemia. For their respective interests in the joint venture the
Company contributed $233,000 and certain technology and Pestka contributed
exclusive rights to phosphorylation technology as applied to Interleukin-2.
Pestka has performed research and development for Cytomune relating to IL-P
using this technology. Additional funding is not required but, if provided, will
permit such research and development to continue. See "Management-Scientific
Advisors/Consultants."
    



         UNIVERSITY OF TEXAS

   
         In June 1992, the Company and the University of Texas at Dallas ("UTD")
entered into an agreement, which has been amended, pursuant to which UTD
performs certain research and development activities relating to anti-sense
compounds and related technology for use in humans as therapeutic and diagnostic
products. Pursuant to the agreement, UTD provides all necessary personnel,
equipment supplies and facilities in consideration for an amended budget not to
exceed $240,240. Inventions under the agreement, if any, will be the property of
UTD. However, UTD must grant the Company the right of first refusal to acquire a
license to develop and commercialize any intellectual property resulting from
the agreement for a royalty to be negotiated, not to exceed 8% of the net sales
(as defined in the agreement) of commercialized products. The Company is not
required to pay any up-front fee or any minimum royalty. The agreement has been
extended through August 1999 in consideration for the Company's agreement to
increase the original funding commitment from $150,240 to $285,240 of which
amount the Company has paid $273,213 as of December 31, 1998.

         In June 1996, the Company entered into a Patent License Agreement (the
"Regents Agreement") with the Board of Regents of the University of Texas System
("Regents") whereby the Company received an exclusive royalty-bearing license to
manufacture, have manufactured, use, sell and sublicense products related to a
U.S. Patent Application entitled, "A Method for Ranking Sequences to Select
Target Sequence Zones of Nucleus Acids." The technology has identified optimum
regions within genes to bind anti-sense products. Anti-sense products are under
development to control genes involved in human diseases such as cancer,
diabetes, or AIDS. This discovery potentially has broad applications to many
human and viral genes involved in human disease. The Company is required to pay
Regents certain royalties and sublicensing fees. The Regents Agreement shall be
in full force and effect until the later of 20 years or the expiration of patent
rights. However, the Regents Agreement will terminate (i) automatically if the
Company's obligations to pay royalties and sublicensing fees are not satisfied
within 30 days after the Company receives written notice of its failure to make
such payment; (ii) upon 90 days' written notice if the Company or Regents shall
breach or default on any obligation under the Regents Agreement; and (iii) upon
60 days' written notice by the Company. In addition, Regents may terminate the
exclusivity of the Regents Agreement at any time after
    

                                       34

<PAGE>   37

   
June 1999 and may terminate the license completely at any time after June 2001
if the Company fails to provide Regents with written evidence that it has
commercialized or is actively attempting to commercialize the licensed product.
There can be no assurance that any revenues will be derived by the Company as a
result of the agreement or that the Regents will not be in a position to
exercise its termination rights.
    


         HELM AG

         The Company entered into a marketing agreement, effective in November
1994, with Helm AG, a world-wide distributor of pharmaceutical and related
products, granting Helm AG the right, in certain parts of Europe, to market the
technology and/or products of, and arrange business introductions for, the
Company on a commission basis. The agreement is terminable by either party on
six months' notice. To date, the Company has no products available for
distribution and thus no revenues have been derived from such agreement. There
can be no assurance that any revenues will be derived by the Company from this
agreement in the future.


         WSURF

   
         In July 1996, the Company entered into the WSURF Agreement with WSURF
whereby the Company received an exclusive, world-wide license to use and/or
sublicense WSURF Technology. The Company is required to pay WSURF license fees
of $7,500 per year, commencing July 1, 1997, as well as certain royalties and
sublicensing fees. The WSURF Agreement shall be in full force and effect until
the last to expire of the patents licensed under the WSURF Technology. However,
the Company may terminate the WSURF Agreement on 90 days' notice provided that
all amounts due to WSURF are paid. WSURF may terminate the WSURF Agreement
immediately if the Company ceases to carry on its business or on 90 days' notice
if the Company is in default in payment of fees or royalties, is in breach of
any provisions of the WSURF Agreement, provides materially false reports or
institutes bankruptcy, insolvency, liquidation or receivership proceedings. In
connection with this agreement, the Company granted WSURF warrants to purchase
36,000 shares of Common Stock at $4.25 per share. Such Warrants vest annually in
12,000 increments commencing July 1999 and expire July 2002. In June 1998, the
Company and WSURF amended the WSURF Agreement therein (i) covering additional
patents, patent applications and genes for enzymes which are expected to be the
subject of future patent filings and (ii) granting to the Company an option,
expiring July 2006, to license any prospective WSURF Technology as it is
developed. There can be no assurance that any revenues will be derived by the
Company as a result of the agreement. See "-Collaborative
Agreements-Bristol-Myers Squibb."
    





PATENTS, LICENSES AND PROPRIETARY RIGHTS

   
         The Company owns and has rights to a number of patents and patent
applications. In 1991, the Company entered into the WadTech Agreement, whereby
it was assigned (i) two issued United States patents (expiring, under current
law, in 2006 and 2007, respectively), (ii) three pending United States patent
applications and (iii) six pending foreign patent applications held by WadTech.
A. U.S. patent for the LCG gene, filed by the Company in July 1994, was issued
on December 31, 1996. A patent for the lung cancer gene market issued in June
1998. Pursuant to the RDI Agreement, the Company has been granted an exclusive
license to the technology contained in the Paclitaxel Fermentation Production
System, including one issued United States patent, one United States patent
application with allowed claims and foreign patent applications. In addition,
UTD had filed a patent application, on which a patent was issued in 1999,
relating to certain anti-sense technology with respect to which, pursuant to the
agreement between the Company and UTD, the Company has a right of first refusal
to acquire a license to develop and commercialize products using such
technology. Pursuant to the UCLA License Agreement I, the Company has been
granted an exclusive license to technology involving the "Inhibition of Cyst
Formation By Cytoskeletal Specific Drugs" and related patent of which the claims
have been allowed by the U.S. Patent and Trademark Office in August 1997.
Pursuant to the UCLA License Agreement III, the Company has been granted an
exclusive world-wide license to technology involving a U.S. patent pending
entitled, "Peptide Antiestrogen Compositions and Methods for Treating Breast
Cancer." In connection with the employment of Dr. Dorit Arad in January 1999,
the Company was assigned patent applications for technology including
"Pharmaceutical Preparation Which Compromises Inhibitors of Cysteine Protease,"
"Modulators of Cysteine Protease," "Novel Antiviral
    

                                       35

<PAGE>   38

   
Compounds," and "Cysteine Protease Inhibitors." In March 1999, a broad patent
issued for the production of Paclitaxel by microorganisms isolated from the
slow growing Pacific yew tree utilizing the technology licensed to the Company
pursuant to the RDI Agreement. See "-Collaborative Agreement; Bristol-Myers
Squibb, -WadTech; -RDI; -UCLA License Agreements and -University of Texas."
    

         The Company's policy is to protect its technology by, among other
things, filing patent applications for technology it considers important in the
development of its business. In addition to filing patent applications in the
United States, the Company has filed, and intends to file, patent applications
in foreign countries on a selective basis. The Company has filed patent
applications relating to its IL-T and Lung Cancer Gene technologies and is
preparing to file additional patent applications, relating primarily to
technologies for vaccines and Paclitaxel production. Although a patent has a
statutory presumption of validity in the United States, the issuance of a patent
is not conclusive as to such validity or as to the enforceable scope of the
claims of the patent. There can be no assurance that the Company's issued
patents or any patents subsequently issued to or licensed by the Company will
not be successfully challenged in the future. The validity or enforceability of
a patent after its issuance by the patent office can be challenged in
litigation. If the outcome of the litigation is adverse to the owner of the
patent, third parties may then be able to use the invention covered by the
patent, in some cases without payment. There can be no assurance that patents in
which the Company has rights will not be infringed or successfully avoided
through design innovation.

         There can be no assurance that patent applications owned by or licensed
to the Company will result in patents being issued or that the patents will
afford protection against competitors with similar technology. It is also
possible that third parties may obtain patent or other proprietary rights that
may be necessary or useful to the Company. In cases where third parties are
first to invent a particular product or technology, it is possible that those
parties will obtain patents that will be sufficiently broad so as to prevent the
Company from using certain technology or from further developing or
commercializing certain products. If licenses from third parties are necessary
but cannot be obtained, commercialization of the related products would be
delayed or prevented. The Company is aware of patent applications and issued
patents belonging to competitors and it is uncertain whether any of these, or
patent applications filed of which the Company may not have any knowledge, will
require the Company to alter its potential products or processes, pay licensing
fees or cease certain activities.

         The Company also relies on unpatented technology, trade secrets and
information and no assurance can be given that others will not independently
develop substantially equivalent information and techniques or otherwise gain
access to the Company's technology or disclose such technology, or that the
Company can meaningfully protect its rights in such unpatented technology, trade
secrets and information. The Company requires each of its employees to execute a
confidentiality agreement at the commencement of an employment relationship with
the Company. The agreements generally provide that all inventions conceived by
the individual in the course of employment or in the providing of services to
the Company and all confidential information developed by, or made known to, the
individual during the term of the relationship shall be the exclusive property
of the Company and shall be kept confidential and not disclosed to third parties
except in limited specified circumstances. There can be no assurance, however,
that these agreements will provide meaningful protection for the Company in the
event of unauthorized use or disclosure of such confidential information.



COMPETITION

   
         All of the Company's proposed products will face competition from
existing therapies. The development by others of novel treatment methods for
those indications for which the Company is developing compounds could render the
Company's compounds noncompetitive or obsolete. This competition potentially
includes all of the pharmaceutical concerns in the world that are developing
pharmaceuticals for the diagnosis and treatment of cancer. Competition in
pharmaceuticals is generally based on performance characteristics, price and
timing of market introduction of competitive products. Acceptance by hospitals,
physicians and patients is crucial to the success of a product. Price
competition may become increasingly important as a result of an increased focus
by insurers and regulators on the containment of health care costs. In addition,
the various federal and state agencies have enacted regulations requiring
rebates of a portion of the purchase price of many pharmaceutical products. See
"Risk Factors-Our Competition."

         Most of the Company's existing or potential competitors have
substantially greater financial, technical and human resources than the Company
and may be better equipped to develop, manufacture and market products. In
addition, many of these companies have extensive experience in pre-clinical
testing, human clinical trials and the regulatory approval process. These
companies may develop and
    


                                       36

<PAGE>   39

   
introduce products and processes competitive with or superior to those of the
Company. See "Risk Factors-Our Competition."

         The Company's competition also will be determined in part by the
potential indications for which the Company's compounds are developed. For
certain of the Company's potential products, an important factor in competition
may be the timing of market introduction of its own or competitive products.
Accordingly, the relative speed with which the Company can develop products,
complete the clinical trials and regulatory approval processes and supply
commercial quantities of the products to the market are expected to be important
competitive factors. The Company expects that competition among products
approved for sale will be based on, among other things, product efficacy,
safety, reliability, availability, price and patent position. See "Risk
Factors-Our Competition; and -- No Assurance of FDA Approval; Government
Regulation."

         The Company's competitive position also depends upon its ability to
attract and retain qualified personnel, obtain patent protection or otherwise
develop proprietary products or processes and secure sufficient capital
resources for the often lengthy period between technological conception and
commercial sales. See "Management."
    



         GOVERNMENT REGULATION

         The production and marketing of the Company's products and its research
and development activities are subject to regulation for safety and efficacy by
numerous governmental authorities in the United States and other countries. In
the United States, drugs and pharmaceutical products are subject to rigorous FDA
review. The Federal Food, Drug, and Cosmetic Act, the Public Health Service Act
and other federal statutes and regulations govern or influence the testing,
manufacture, safety, labeling, storage, record keeping, approval, advertising
and promotion of such products. Non-compliance with applicable requirements can
result in fines, recall or seizure of products, total or partial suspension of
production, refusal of the government to approve product license applications or
allow the Company to enter into supply contracts and criminal prosecution. The
FDA also has the authority to revoke product licenses and establishment licenses
previously granted.

   
         In order to obtain FDA approval of a new product, the Company must
submit proof of safety, purity, potency and efficacy. In most cases, such proof
entails extensive pre-clinical, clinical and laboratory tests. The testing,
preparation of necessary applications and processing of those applications by
the FDA is expensive and may take several years to complete. There is no
assurance that the FDA will act favorably or quickly in making such reviews, and
significant difficulties or costs may be encountered by the Company in its
efforts to obtain FDA approvals that could delay or preclude the Company from
marketing any products it may develop. The FDA may also require post-marketing
testing and surveillance to monitor the effects of approved products or place
conditions on any approvals that could restrict the commercial applications of
such products. Product approvals may be withdrawn if compliance with regulatory
standards is not maintained or if problems occur following initial marketing.
With respect to patented products or technologies, delays imposed by the
governmental approval process may materially reduce the period during which the
Company will have the exclusive right to exploit them.

         The time period between when a promising new compound is identified and
when human testing is initiated is generally referred to as the pre-clinical
development period. During this time, a manufacturing process is identified and
developed to be capable of producing the compound in an adequately pure and well
characterized form for human use. Production of compounds for use in humans is
governed by a series of FDA regulations known as Good Manufacturing Practices,
which govern all aspects of the manufacturing process. The FDA has published a
"Points to Consider" guidance document with respect to the manufacture of MAbs
for human use.

         The FDA approval process for a new and unfamiliar term or drug involves
completion of pre-clinical studies and the submission of the results of these
studies to the FDA in an IND application. Pre-clinical studies involve
laboratory evaluation of product characteristics and animal studies to assess
the efficacy and safety of the product. Pre-clinical studies are regulated by
the FDA under a series of regulations called the Good Laboratory Practices
("GLP") regulations. Violations of these regulations can, in some cases, lead to
invalidation of the studies, requiring those studies to be replicated.
    

         Once the IND is approved, human clinical trials may be conducted. Human
clinical trials are typically conducted in three sequential phases, but the
phases may overlap. Phase I trials consist of testing the product in a small -
number of volunteers, primarily for safety at one or more doses. In Phase II, in
addition to safety, the efficacy of the product is evaluated in a patient
population somewhat larger than Phase I trials. Phase III trials typically
involve additional testing for safety and clinical efficacy in an expanded
population


                                       37

<PAGE>   40

at geographically dispersed test sites. A clinical plan, or "protocol,"
accompanied by the approval of the institution participating in the trials, must
be submitted to the FDA prior to commencement of each clinical trial. The FDA
may order the temporary or permanent discontinuation of a clinical trial at any
time.

         To date an IND was submitted for the LCG-MAb clinical trials at Wadley.
The Company intends to file an IND for a humanized form of the LCG-MAb followed
by clinical trials. The results of the pre-clinical and clinical testing are
submitted to the FDA in the form of a New Drug Application ("NDA") or, in the
case of a biologic, such as LCG-MAb and other MAbs, as part of a product license
application ("PLA"). In a process which generally takes several years, the FDA
reviews this application and once, and if, it decides that adequate data is
available to show that the new compound is both safe and effective, approves the
drug or biologic product for marketing. The amount of time taken for this
approval process is a function of a number of variables including the quality of
the submission and studies presented, the potential contribution that the
compound will make in improving the treatment of the disease in question and the
workload at the FDA. There can be no assurance that any new drug will
successfully proceed through this approval process or that it will be approved
in any specific period of time.

         The FDA may, during its review of an NDA or PLA, ask for the production
of additional test data. If the FDA does ultimately approve the product, it may
require post-marketing testing, including potentially expensive Phase IV
studies, and surveillance to monitor the safety and effectiveness of the drug.
In addition, the FDA may in some circumstances impose restrictions on the use of
the drug that may be difficult and expensive to administer and may seek to
require prior approval of promotional materials.

         Manufacture of a biologic product must be in a facility covered by an
FDA-approved Establishment License Application. Manufacture, holding, and
distribution of both biologic and non-biologic drugs must be in compliance with
GMPs. Manufacturers must continue to expend time, money, and effort in the area
of production and quality control and record keeping and reporting to ensure
full compliance with those requirements. The labeling, advertising, and
promotion of a drug or biologic product must be in compliance with FDA
regulatory requirements. Failures to comply with applicable requirements
relating to manufacture, distribution, or promotion can lead to FDA demands that
production and shipment cease, and, in some cases, that products be recalled, or
to enforcement actions that can include seizures, injunctions, and criminal
prosecution. Such failures can also lead to FDA withdrawal of approval to market
the product.

         The FDA may designate a biologic or drug as an Orphan Drug for a
particular use, in which event the developer of the biologic or drug may request
grants from the government to defray the costs of certain expenses related to
the clinical testing of such drug and be entitled to a seven year marketing
exclusivity period.

   
         The Company's ability to commercialize its products successfully may
also depend in part on the extent to which reimbursement for the cost of such
products and related treatment will be available from government health
administration authorities, private health insurers and other organizations.
Such third-party payers are increasingly challenging the price of medical
products and services. Several proposals have been made that may lead to a
government-directed national health care system. Adoption of such a system could
further limit reimbursement for medical products and services. Significant
uncertainty exists as to the reimbursement status of newly approved health care
products, and there can be no assurance that adequate third-party coverage will
be available to enable the Company to maintain price levels sufficient to
realize an appropriate return on this investment in product development.

         The Company is also subject to regulation by the Occupational Safety
and Health Administration ("OSHA") and the Environmental Protection Agency
("EPA") and to regulation under the Toxic Substances Control Act, the Resource
Conservation and Recovery Act and other regulatory statutes, and may in the
future be subject to other federal, state or local regulations. Either or both
of OSHA or the EPA may promulgate regulations that may affect the Company's
research and development programs. The Company is unable to predict whether any
agency will adopt any regulation which could have a material adverse effect on
the Company's operations.

         Sales of pharmaceutical products outside the United States are subject
to foreign regulatory requirements that vary widely from country to country.
Whether or not FDA approval has been obtained, approval of a product by
comparable regulatory authorities of foreign countries must be obtained prior to
the commencement of marketing the product in those countries. The time required
to obtain such approval may be longer or shorter than that required for FDA
approval. See "Risk Factors-No Assurance of FDA Approval; Government
Regulation."

MANUFACTURING AND MARKETING

   
         Neither the Company nor any of its officers or employees has
pharmaceutical marketing experience. Furthermore, the Company has never
manufactured or marketed any products and the Company does not have the
resources to manufacture or market on a commercial scale any products that it
may develop. The Company's long-term objective is to manufacture and market
certain of its products and to rely on independent third parties for the
manufacture of certain of its other products. For the foreseeable future, the
Company will be required to rely on corporate partners or others to manufacture
or market products it develops, although no specific arrangements have been
made. No assurance can be given that the Company will enter into any such
arrangements on acceptable terms. See "Collaborative Agreement-Helm AG."
    

         Manufacturing. While the Company intends to select manufacturers that
comply with GMP and other regulatory standards, there can be no assurance that
these manufacturers will comply with such standards, that they will give the
Company's orders the highest priority or that the Company would be able to find
substitute manufacturers, if necessary. In order for the Company to establish a
manufacturing facility, the Company will require substantial additional funds
and will be required to hire and retain significant additional personnel and
comply with the extensive GMP regulations of the FDA applicable to such a
facility. No assurance can be given that the Company will be able to make the
transition successfully to commercial production, should it choose to do so.

   
         Marketing. Despite the Company's strategy to develop products for sale
to concentrated markets, significant additional expenditures and management
resources will be required to develop an internal sales force, and there can be
no assurance that the Company will be successful in penetrating the markets for
any products developed. For certain products under development, the Company may
seek to enter into development and marketing agreements which grant exclusive
marketing rights to its corporate partners in return for royalties to be
received on sales, if any. Under certain of these agreements, the Company's
marketing partner may have the responsibility for all or a significant portion
of the development and regulatory approval. In the event that the marketing and
development partner fails to develop a marketable product or fails to market a
product successfully, the Company's business may be adversely affected. The sale
of certain products outside the United States will also be dependent on the
successful completion of arrangements with future partners, licensees or
distributors in each territory. There can be no assurance that the Company will
be successful in establishing any additional collaborative arrangements, or
that, if established, such future partners will be successful in commercializing
products. See "Collaborative Agreement-Helm AG."
    



PRODUCT LIABILITY INSURANCE

         The testing, marketing and sale of human health care products entail an
inherent risk of allegations of product liability, and there can be no assurance
that product liability claims will not be asserted against the Company. The
Company intends to obtain product liability insurance for its ongoing clinical
trials. Such coverage may not be adequate as and when the Company further
develops products. There can be no assurance that the Company will be able to
obtain, maintain or increase its insurance coverage in the future on acceptable
terms or that any claims against the Company will not exceed the amount of such
coverage.



HUMAN RESOURCES

   
         As of April 5, 1999, the Company had 19 full-time employees, 15 of whom
were engaged directly in research and development activities, including 8
Ph.D.s, and 4 of whom were in executive and administrative positions. The
Company's employees are not governed by any collective bargaining agreement and
the Company believes that its relationship with its employees is good. See
"Management."



PROPERTY

         The Company occupies an aggregate of approximately 21,400 square feet
of both office and laboratory space in Dallas, Texas at two separate facilities.
The Company leases approximately 4,800 square feet of office and laboratory
space pursuant to a lease agreement expiring in August 1999. In addition, the
Company occupies an additional approximate 16,600 square feet of office and
laboratory space, including approximately 11,000 square feet added in 1999,

         The Board of Directors currently consists of four members. All
directors hold office until the next annual meeting of stockholders and until
their successors are duly elected and qualified. Officers are elected to serve,
subject to the discretion of the Board of Directors, until their successors are
appointed.

   
         Directors receive fees of $1,000 per month, or an annual fee of
$12,000. Dr. Gelb has, to date, also received options to purchase 129,000
shares of Common Stock with exercise prices ranging from $2.69 to $5.00 per
share. Mr. Gerson has, to date, received options to purchase 125,000 shares of
Common Stock with exercise prices ranging from $2.69 to $5.00 per share. Dr.

connection with their attendance at meetings of the Board of Directors.
    

         The Company's Certificate of Incorporation includes certain provisions
permitted pursuant to Delaware law whereby officers and directors of the
Company are to be indemnified against certain liabilities. The Company's
Certificate of Incorporation also limits, to the fullest extent permitted by
Delaware law, a director's liability for monetary damages for breach of
fiduciary duty, including gross negligence, except liability for (i) breach of
the director's duty of loyalty, (ii) acts or omissions not in good faith or
which involve


                                       42

<PAGE>   45


intentional misconduct or a knowing violation of the law, (iii) the unlawful
payment of a dividend or unlawful stock purchase or redemption and (iv) any
transaction from which the director derives an improper personal benefit.
Delaware law does not eliminate a director's duty of care and this provision has
no effect on the availability of equitable remedies such as injunction or
rescission based upon a director's breach of the duty of care. In addition, the
Company has obtained an insurance policy providing coverage for certain
liabilities of its officers and directors.

   
         The Company has been advised that it is the position of the Commission
that insofar as the foregoing provision may be invoked to disclaim liability for
damages arising under the Securities Act, such provision is against public
policy as expressed in the Securities Act and is therefore unenforceable.

have consulting agreements with entities other than the Company, some of which
entities may in the future compete with the Company. Four of the current
scientific advisors receive $1,000 per month from the Company. The scientific
advisors are expected to devote only a small portion of their time to the
Company and are not expected to participate actively in the day-to-day affairs
of the Company. Certain of the institutions with which the scientific advisors
are affiliated may adopt new regulations or policies that limit the ability of
the scientific advisors to consult with the Company. It is possible that any
inventions or processes discovered by the scientific advisors will remain the
property of such persons or of such persons' employers. In addition, the
institutions with which the scientific advisors are affiliated may make
available the research services of their personnel, including the scientific
advisors, to competitors of the Company pursuant to sponsored research
agreements.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS

   
         Arthur P. Bollon, Ph.D. is employed under an extension effective
October 8, 1998 to his 1992 employment agreement with the Company, which
agreement has been extended until November 6, 2003. As extended, the agreement
provides for the payment to Dr. Bollon of a base salary of $200,000 per year
with annual increases of not less that 5% per year. In addition, in the event
Dr. Bollon is terminated without just cause or due to a Disability (as defined
in the employment agreement), the employment agreement provides that Dr. Bollon
shall receive severance payments of equal monthly installments at the base rate
until the earlier of the expiration of the term or the expiration of 36 months.
Dr. Bollon also receives a car expense allowance of $500 per month under the
employment agreement. In November 1992, the Company granted Dr. Bollon options
to purchase 200,000 shares of Common Stock, at an exercise price of $1.65

per share. In April 1996, the Company granted Dr. Bollon options to purchase
50,000 shares of Common Stock at an exercise price of $4.125 per share. In
December 1996, the Company granted Dr. Bollon options to purchase 100,000 shares

exercisable to the extent of 40% after six months of continuous employment from
the date of grant and to the extent of an additional 20% on and after each of
the first three anniversaries of the date of grant. In October 1998, the
Company's Board of Directors approved an amendment to Dr. Bollon's employment
agreement, to extend the term until November 6, 2003 and to increase his base
salary to $200,000 per annum. See "-Stock Options."
    

         Each of the Company's executive officers and the Company's principal
scientists have entered into confidentiality and patent assignment agreements
with the Company.

STOCK OPTIONS

   
         In October 1992, the Board of Directors of the Company adopted the
Cytoclonal Pharmaceutics Inc. 1992 Stock Option Plan (the "1992 Plan"). The 1992
Plan provides for the grant of incentive stock options intended to qualify as
such under Section 422 of the Internal Revenue Code of 1986, as amended, and
nonstatutory stock options which do not so qualify. Under the 1992 Plan, as
amended, 520,000 shares of Common Stock were reserved for issuance to officers,
employees, consultants and advisors of the Company. As of December 31, 1998,
options to purchase 218,500 shares of Common Stock had been exercised, no shares
are available for future grant and options to purchase 301,500 shares of Common
Stock remain outstanding under the 1992 Plan. The exercise prices of such
options range from $1.65 to $5.00 per share. In April 1996, the Board of
Directors of the Company adopted the Cytoclonal Pharmaceutics Inc. 1996 Stock
Option Plan (the "1996 Plan"). Under the 1996 Plan, 750,000 shares of Common
Stock had been reserved for issuance to officers, employees, consultants and
advisors of the Company. The 1996 Plan provides for the grant of incentive stock
options intended to qualify as such under Section 422 of the Internal Revenue
Code of 1986, as amended, and nonstatutory stock options which do not so
qualify. On August 22, 1998 and October 2, 1998, Amendment No. 1 to the 1996
Plan was approved by the Company's Board of Directors and stockholders,
respectively, thereby increasing the number of stock options available for grant
pursuant to the 1996 Plan and shares of Common Stock issuable thereunder from
750,000 to 1,500,000. As of December 31, 1998, options to purchase 4,200 shares
of Common Stock have been exercised, options to purchase 487,000 shares of
Common Stock are available for future grant and options to purchase 1,008,800
shares of Common Stock remain outstanding under the 1996 Plan. The exercise
prices of such options range from $2.25 to $8.375 per share. All such options
are exercisable to the extent of 40% after six months of continuous employment
from the date of grant and to the extent of an additional 20% on and after each
of the first three anniversaries of the date of grant. See "Item 4. Submission
of Matters to a Vote of Security Holders."

         The 1992 Plan and the 1996 Plan are administered by the Compensation
Committee of the Board of Directors (the "Compensation Committee"). Subject to
the limitations set forth in the 1992 Plan and the 1996 Plan, the Compensation
Committee has the authority to determine to whom options will be granted, the
term during which options granted under the 1992 and the 1996 Plan may be
exercised, the exercise price of options and the rate at which options may be
exercised. The maximum term of each incentive stock option granted under the
1992 and the 1996 Plan is ten years. The exercise price of shares of Common
Stock subject to options qualifying as incentive stock options may not be less
than the fair market value of the Common Stock on the date of the grant. The
exercise price of incentive options granted under the 1992 and the 1996 Plan to
any participant who owns stock possessing more than 10% of the total combined
voting power of all classes of outstanding stock of the Company must be equal to
no less than 110% of the fair market value on the date of grant, and incentive
stock options granted to such participants must also expire within five years
from the date of grant. Under the 1992 Plan, the exercise price of both
incentive stock options and nonstatutory stock options is payable in cash or, at
the discretion of the Board, in Common Stock or a combination of cash and Common
Stock. Under the 1996 Plan, the exercise price of options is payable in cash or
such other means which the Board determines are consistent with such Plan and
with applicable laws and regulations.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

   
         JMA acted as placement agent for the 1995 Bridge Financing and as
underwriter of the IPO and in consideration thereof, received fees of $203,750
and $1,092,500, respectively, plus non-accountable expense allowances of $61,125
and $345,000, respectively. In addition, JMA was granted, in connection with its
services as placement agent for the 1995 Bridge Financing, a (i) five-year right
of first refusal to act as agent for offerings of securities by the Company and
certain of its shareholders and (ii) the right to receive certain fees in
connection with any merger and acquisition pursuant to an agreement with the
Company. In connection with its services as underwriter of the IPO, JMA was
granted options to purchase 200,000 units ("Units") at a price equal to $8.25
per Unit, each Unit consisting of one share of Common Stock, one redeemable
Class C Warrant and one redeemable Class D Warrant.

         JMA acted as placement agent for the Company's 1998 Private Placement
and, in consideration for its services as such, received a sales commission
equal to 10% of the $5,633,675 gross proceeds, or $563,368, a non-accountable
expense allowance equal to 3%, or $169,010, accountable out-of-pocket expenses
equal to $13,658, plus legal and blue sky fees of $48,610. JMA also received a
warrant, exercisable for a five-year period commencing April 2, 1998, to
purchase 20% of the number of Units sold in the 1998 Private Placement for
134,199 shares of Common Stock and Common Stock Purchase Class E Warrants to
purchase 67,101 shares of Common Stock (the "Private Placement Unit Purchase
Option").

         Bruce Meyers is a principal of JMA and was Vice Chairman of the Board
of Directors and Vice President in charge of Business Development for the
Company until his resignation from the Company in April 1995. In December 1996,
the Company and JMA executed a one year nonexclusive investment banking
agreement with the Company providing for a monthly fee of $5,000 payable by the
Company to JMA. During each of 1997 and 1998, the Company paid $60,000 under
this agreement. This agreement was extended through January 1999. See
"Management-Security Ownership of Certain Beneficial Owners and Management."
    


                            DESCRIPTION OF SECURITIES

and one Class D Warrant at an exercise price of $6.50, subject to adjustment.
Each Class D Warrant entitles the holder thereof to purchase one share of Common

AUTHORIZED STOCK

         The authorized capital stock of the Company consists of 30,000,000
shares of Common Stock, par value $.01 per share, and 10,000,000 shares of
Preferred Stock, par value $.01 per share.



COMMON STOCK

   
         Of the authorized Common Stock, 10,290,380 shares were outstanding as
of April 5, 1999 and were held by more than approximately 300 record holders.
Subject to the prior rights of the holders of any shares of Preferred Stock
currently outstanding or which may be issued in the future, the holders of the
Common Stock are entitled to receive dividends from funds of the Company legally
available therefor when, as and if declared by the Board of Directors of the
Company, and are entitled to share ratably in all of the assets of the Company
available for distribution to holders of Common Stock upon the liquidation,
dissolution or winding-up of the affairs of the Company subject to the
liquidation preference, if any, of any then outstanding shares of Preferred
Stock of the Company. Holders of the Common Stock do not have any preemptive,
subscription, redemption or conversion rights. Holders of the Common Stock are
entitled to one vote per share on all matters which they are entitled to vote
upon at meetings of stockholders or upon actions taken by written consent
pursuant to Delaware corporate law. The holders of Common Stock do not have
cumulative voting rights, which means that the holders of a plurality of the
outstanding shares can elect all of the directors of the Company. All of the
shares of the Common Stock currently issued and outstanding are, and the shares
of the Common Stock to be issued upon exercise of the Warrants, when paid for in
accordance with the terms will be, fully-paid and nonassessable. No dividends
have been paid to holders of the Common Stock since the incorporation of the
Company, and no dividends are anticipated to be declared or paid in the
reasonably foreseeable future. See "Dividend Policy." The Common Stock, Class C
Warrants and Class D Warrants are quoted on the Nasdaq SmallCap Market under the
symbols "CYPH," "CYPHW" and "CYPHZ," respectively. There can be no assurance,
however, that the securities will not be delisted from the Nasdaq SmallCap
Market. See "Risk Factors - Possible Delisting of Securities from the Nasdaq
Stock Market."
    



PREFERRED STOCK

         The Board of Directors of the Company has the authority, without
further action by the holders of the outstanding Common Stock, to issue
Preferred Stock from time to time in one or more classes or series, to fix the
number of shares constituting any class or series and the stated value thereof,
if different from the par value, and to fix the terms of any such series or
class, including dividend rights, dividend rates, conversion or exchange rights,
voting rights, rights and terms of redemption (including sinking fund
provisions), the redemption price and the liquidation preference of such class
or series. The Company presently has one series of Preferred Stock outstanding,
designated as the Company's Series A Convertible Preferred Stock (the "Series A
Preferred Stock"). The Company has no present plans to issue any other series or
class of Preferred Stock. The designations, rights and preferences of the Series
A Preferred Stock is set forth in the Certificate of Designations of Series A
Convertible Preferred Stock, which has been filed with the Secretary of State of
the State of Delaware.

   
         Series A Preferred Stock. Of the authorized Preferred Stock, 4,000,000
shares have been designated Series A Preferred Stock, of which 757,673 shares
were issued and outstanding as of April 5, 1999. Dividends are payable on the
Series A Preferred Stock in the amount of $.25 per share, payable annually in
arrears. At the option of the Board of Directors of the Company, dividends will
be paid either (i) wholly or partially in cash or (ii) in newly issued shares of
Series A Preferred Stock valued at $2.50 per share to the extent a cash dividend
is not paid. Shares of Series A Preferred Stock were issued in January 1993 as
partial payment of the dividend due on the Series A Preferred Stock for the year
ended December 31, 1992 (the remaining dividend was paid in cash). 104,869
shares of Series A Preferred Stock were issued in January 1994 as full payment
of the dividend due on the Series A Preferred Stock for the year ended December
31, 1993. 115,307 shares of Series A Preferred Stock were issued in January 1995
as full payment of the dividend due on Series A Preferred Stock for the year
ended December 31, 1994. 126,888 shares of Series A Preferred Stock were issued
in January 1996 as full payment of the dividend due on the Series A Preferred
Stock for the year ended December 31, 1995. 122,788 shares of the Series A
Preferred Stock
    


                                       48

<PAGE>   51

   
were issued in January 1997 as full payment of the dividend due on the Series A
Preferred Stock for the year ended December 31, 1996. 94,680 shares of the
Series A Preferred Stock were issued in January 1998 as full payment of the
dividend due on the Series A Preferred Stock for the year ended December 31,
1997. 74,648 shares of the Series A Preferred Stock were issued in January 1999
as full payment of the dividends due the Series A Preferred Stock for the year
ended December 31, 1998. See "Dividend Policy." Holders of Series A Preferred
Stock have the right to convert their shares, at their option exercisable at any
time, into shares of Common Stock of the Company on a one-for-one basis subject
to anti-dilution adjustments. These anti-dilution adjustments are triggered in
the event of any subdivision or combination of the Company's outstanding Common
Stock, any payment by the Company of a stock dividend to holders of the
Company's Common Stock or other occurrences specified in the Certificate of
Designations relating to the Series A Preferred Stock. The Company may elect to
convert the Series A Preferred Stock into Common Stock or a substantially
equivalent preferred stock in case of a merger or consolidation of the Company
in which the Company does not survive, a sale of all or substantially all of the
Company's assets or a substantial reorganization of the Company. Each share of
Series A Preferred Stock is entitled to one vote on all matters on which the
Common Stock has the right to vote. Holders of Series A Preferred Stock are also
entitled to vote as a separate class on any proposed adverse change in the
rights, preferences or privileges of the Series A Preferred Stock and any
increase in the number of authorized shares of Series A Preferred Stock. The
Company, at its sole option, has the right to redeem all or any portion of the
Series A Preferred Stock at $2.50 per share plus accrued and unpaid dividends.
In the event of any liquidation or winding-up of the Company, the holders of the
Series A Preferred Stock will be entitled to receive $2.50 per share plus any
accrued and unpaid dividends before any distribution to the holders of the
Common Stock.
    


         The Series A Preferred Stock was originally sold by the Company as part
of a private placement of Units consisting of 10,000 shares of Series A
Preferred Stock and 20,000 shares of Common Stock (the "Private Placement
Units") in January and February 1992 (the "1992 Private Placement"). A total of
100 Private Placement Units were sold in the 1992 Private Placement at a
purchase price of $50,000 per unit. In addition, the placement agent for the
1992 Private Placement, D.H. Blair Investment Banking Corp. ("Blair"), received
options to purchase ten Private Placement Units, or an aggregate of 100,000
shares of Series A Preferred Stock and 200,000 shares of Common Stock, at a
purchase price of $50,000. Blair transferred to Peter Janssen options to
purchase three Private Placement Units and to Bruce Meyers options to purchase
two Private Placement Units. These options were exercised in February 1997. The
Company has filed a Registration Statement on Form S-3 registering 150,000 of
such shares.



   
CLASS A WARRANTS AND CLASS B WARRANTS ("BRIDGE WARRANTS")

         There were 782,720 outstanding Bridge Warrants ("Bridge Warrants") as
of April 5, 1999 to purchase an aggregate of 313,088 shares of Common Stock.
Each warrant entitles the holder to purchase four-tenths of a share of Common
Stock. The Bridge Warrants consist of 300,000 Class A Warrants to purchase
120,000 shares of Common Stock and 482,720 Class B Warrants to purchase 193,088
shares of Common Stock. The Class A Warrants are exercisable at $3.75 per share
of Common Stock and the Class B Warrants are exercisable at $4.375 per share of
Common Stock. The Bridge Warrants are all currently exercisable and expire in
November 2000. The Bridge Warrants contain provisions that protect holders
thereof from dilution by adjustment of the exercise price and rate in the event
of a merger, acquisition, recapitalization or split-up of shares of the Company,
the issuance by the Company of a stock dividend, sales of stock below current
market price and other unusual events. In addition, Blair was granted options to
acquire up to 506,250 Bridge Warrants to purchase 202,500 shares of Common Stock
at an exercise price of $3.75 per share (the "Blair Warrants"). These options
were granted to Blair as part of its compensation for services as placement
agent in the Company's Bridge Financing which was completed in August 1994 and
in connection with the waiver of certain rights. 150,000 shares of Common Stock
issuable upon exercise of the Bridge Warrants have been registered by the
Company on an effective Registration Statement with the Commission. See "Bridge
Financings."

CLASS C WARRANTS AND CLASS D WARRANTS
    

         The following discussion of the terms and provisions of the Class C and
Class D Warrants is qualified in its entirety by reference to the warrant
agreement (the "Warrant Agreement") between the Company, JMA and American Stock
Transfer and Trust Company, the warrant agent (the "Warrant Agent"). The
Warrants will be evidenced by warrant certificates in registered form.

   
         As of April 5, 1999, the Company has 2,006,073 Class C Warrants and
2,510,927 Class D Warrants (other than the Bridge Warrants) outstanding.
    

         Class C Warrants. The holder of each Class C Warrant is entitled to
purchase one share of Common Stock and one Class D Warrant at an aggregate
exercise price of $6.50. The Class C Warrants are exercisable at any time until
November 2, 2000, provided that at such time a current prospectus under the
Securities Act relating to the Common Stock and the Class D Warrants is then in
effect and the Common Stock and the Class D Warrants are qualified for sale or
exempt from qualification under applicable state securities laws. The Class C
Warrants are subject to redemption, as described below.

         Class D Warrants. The holder of each Class D Warrant is entitled to
purchase one share of Common Stock at an exercise price of $8.75. The Class D
Warrants are exercisable at any time after issuance until November 2, 2000,
provided that at such time a current prospectus under the Securities Act
relating to the Common Stock is then in effect and the Common Stock is qualified
for sale or exempt from qualification under applicable state securities laws.
The Class D Warrants issuable upon exercise of the Class C Warrants are, upon
issuance, transferable separately from the Common Stock and Class C Warrants.
The Class D Warrants are subject to redemption, as described below.

   
         Redemption. Since November 2, 1996, the Warrants have been subject to
redemption at the option of the Company, on not less than 30 days' prior written
notice, at a price of $.05 per Warrant, if the average closing bid price of the
Common Stock for any 30 consecutive business day period ending within 15
business days of the date on which the notice of redemption is given exceeds
$9.10 per share, subject to adjustment, with respect to the Class C Warrants and
$12.25 per share, subject to adjustment, with respect to the Class D Warrants.
For these purposes, the closing bid price of the Common Stock shall be
determined by the closing bid price, as reported by Nasdaq, so long as the
Common Stock is quoted on the Nasdaq SmallCap Market or if the Common Stock is a
Nasdaq National Market security or listed on a securities exchange, shall be
determined by the last reported sales price. The Company's redemption rights
will be in effect only if the Common Stock is either quoted on Nasdaq or listed
on a securities exchange. Holders of Warrants will automatically forfeit their
rights to purchase the shares of Common Stock issuable upon exercise of such
Warrants unless the Warrants are exercised before they are redeemed. All of the
outstanding Warrants of a class, except for those underlying the IPO Unit
Purchase Option, must be redeemed if any portion of that class are to be
redeemed. The Warrants underlying the IPO Unit Purchase Option are subject to
redemption if, at the time of a call for redemption, the IPO Unit Purchase
Option has been exercised and such Warrants are then outstanding. A notice of
redemption will be mailed to each of the registered holders of the Warrants no
later than 30 days before the date fixed for redemption. The notice of
redemption shall specify the redemption price, the date fixed for redemption,
the place where the Warrant certificates shall be delivered and the date of
expiration of the right to exercise the Warrants.
    

         IPO Unit Purchase Option. Pursuant to an agreement by and between the
Company and the Underwriters in the IPO, the Company sold to the Underwriters,
or their designee(s), for nominal consideration, a unit purchase option (the
"IPO Unit Purchase Option") to purchase up to an aggregate of 200,000 Units at
$8.25 per Unit, subject to certain anti-dilution adjustments. The Units
purchasable upon exercise of the IPO Unit Purchase Option are identical to the
Units offered in the IPO, except that the Warrants issuable in connection
therewith are subject to redemption, if at the time of a call for redemption the
IPO Unit Purchase Option has been exercised and such Warrants are then
outstanding, and have certain different anti-dilution provisions. The IPO Unit
Purchase Option will be exercisable during the two-year period commencing on
November 2, 1998. The IPO Unit Purchase Option is not transferable for the
three-year period commencing on the date of issuance, except that it may be
assigned in whole or in part to any officer of the underwriters or member of the
selling group. During the term of the IPO Unit Purchase Option, the holder
thereof is given, at nominal cost, the opportunity to profit from a rise in the
market price of the Common Stock by exercising such Option, with a resulting
dilution in the interests of other Company stockholders. As a result, the
Company may find it more difficult to raise additional equity capital if it
should be needed for the operation of the Company while the IPO Unit Purchase
Option is outstanding. Moreover, at any time when the holder(s) of the IPO Unit
Purchase Option might be expected to exercise it, the Company would probably be
able to obtain additional equity capital


                                       50

<PAGE>   53


on terms more favorable than those provided by the IPO Unit Purchase Option. The
Company has agreed to register under the Securities Act on two separate
occasions, the first at its own expense, the IPO Unit Purchase Option and/or the
securities underlying it at the request of the holder thereof. The Company has
also agreed to provide certain "piggy-back" registration rights for the
holder(s) of the IPO Unit Purchase Option and/or the securities underlying it.

         General. The Warrants may be exercised upon surrender of the
certificate therefor on or prior to the expiration or redemption date (as
explained above) at the offices of the Company's Warrant Agent with the form of
"Election to Purchase" on the reverse side of the certificate filled out and
executed as indicated, accompanied by payment (in the form of a certified or
cashier's check payable to the order of the Company) of the full exercise price
for the number of Warrants being exercised. The Company, in its discretion, has
the right to reduce the exercise price of either or both classes of Warrants
subject to compliance with Rule 13e-4 promulgated under the Exchange Act, if
applicable.

         The Warrants contain provisions that protect the holders thereof
against dilution by adjustment of the exercise price and rate in certain events,
such as stock dividends, stock splits or combinations, mergers, sales of all or
substantially all of the Company's assets at less than market value, sales of
stock at below market price and other unusual events.

   
         The Company is not required to issue fractional shares and in lieu
thereof will make a cash payment based upon the current market value of such
fractional shares (determined as the mean between the last reported bid and
asked prices reported or, if the Common Stock is quoted on the Nasdaq National
Market System or traded on a securities exchange, the last reported sales price,
in each case as of the last business day prior to the date of exercise). The
holder of a Warrant will not have any rights as a stockholder of the Company
unless and until the Warrant is exercised.

CLASS E WARRANTS

         In April 1998, the Company completed a private placement of 56.3 Units
under Rule 506 of Regulation D and Section 4(2) of the Securities Act (the "1998
Private Placement"). Each Unit consisted of Common Stock and Class E Warrants.
The number of shares of Common Stock each investor purchased was determined by
dividing the price of a Unit, $100,000, by the 30-day average closing bid price
of the Common Stock as reported by the Nasdaq SmallCap Market. The average
closing bid price ranged from $8.18 to $9.46 during the eight separate closings
of the 1998 Private Placement. The number of Class E Warrants each investor
purchased was equal to one-half the number of shares of Common Stock each such
investor purchased in the same closing having an exercise price equal to 120% of
the purchase price of the Common Stock. Each Class E Warrant entitles the holder
to purchase one share of Common Stock at any time until April 2, 2003, 5:00 p.m.
(EST). The Company also granted a unit purchase option to Jansen-Meyers
Associates, L.P. ("JMA") for its services as placement agent in the 1998 Private
Placement. JMA has the right to purchase 20% of the Units sold in the 1998
Private Placement until April 2, 2003, 5:00 p.m. (EST) at a purchase price equal
to purchase price of the Units. The unit purchase option is exercisable for
134,199 shares of Common Stock at prices ranging from $8.18 to $9.46 per share
and Class E Warrants to purchase 67,101 shares of Common Stock at exercise
prices ranging from $9.82 to $11.35 per share.
    

TRANSFER AGENT AND WARRANT AGENT

         American Stock Transfer and Trust Company will serve as the Transfer
Agent for the Common Stock and Warrants and as Warrant Agent for the Warrants.

REGISTRATION RIGHTS

   
         As of April 5, 1999, holders of (i) 2,000,000 shares of Common Stock
outstanding, (ii) options to purchase 200,000 shares of Common Stock, (iii)
757,673 shares of Series A Preferred Stock convertible into an equal number of
shares of Common Stock and (iv) options to purchase 100,000 shares of Series A
Preferred Stock convertible into an equal number of shares of Common Stock (the
Common Stock referred to in (i) through (iv) above, collectively, the
"Registrable Securities") are entitled to demand and "piggy-back" registration
rights with respect to such Registrable Securities through November 2, 2000. The
holders of more than 50% of the Registrable Securities may request that the
Company file a registration statement under the Securities Act, and, subject to
certain conditions, the Company generally will be required to use its best
efforts to effect any such registration. In addition, if the Company proposes to
register
    


                                       51

<PAGE>   54

   
any of its securities, either for its own account or for the account of other
stockholders, the Company is required, with certain exceptions, to notify the
holders described above and, subject to certain limitations, to include in the
first two such registration statements filed by November 2, 2000, all of the
shares of the Registrable Securities requested to be included by such holders.
In addition, the Company has (i) registered the 810,000 shares of Common Stock
issuable upon the exercise of the Bridge Warrants (including the warrants
underlying the option granted to the placement agent of the 1994 Bridge
Financing); (ii) registered 150,000 shares of Common Stock issuable upon
exercise of the Blair Warrants; (iii) granted certain "piggy-back" registration
rights to the holders of 20,000 shares of Common Stock issued by the Company in
connection with the formation of the joint venture with Pestka Biomedical
Laboratories, Inc.; (iv) registered 750,000 shares of Common Stock issuable upon
exercise of options authorized for grant under the 1996 Plan, as amended; (v)
granted certain "piggy-back" registration rights to the holders of options and
warrants to acquire an aggregate of 170,000 shares of Common Stock granted and
issued in connection with financial advisory and public relations services
rendered to the Company and pursuant to a license agreement. The exercise of one
or more of these registration rights may involve substantial expense to the
Company and may adversely affect the terms upon which the Company may obtain
additional financing.
    


BUSINESS COMBINATION PROVISIONS

         The Company is subject to a Delaware statute regulating "business
combinations," defined to include a broad range of transactions, between
Delaware corporations and "interested stockholders," defined as persons who have
acquired at least 15% of a corporation's stock. Under the law, a corporation may
not engage in any business combination with any interested stockholder for a
period of three years from the date such person became an interested stockholder
unless certain conditions are satisfied. The statute contains provisions
enabling a corporation to avoid the statute's restrictions.

         At this time, the Company will not seek to "elect out" of the statute
and, therefore, upon closing of this offering and the registration of its
securities under the Exchange Act, the restrictions imposed by such statute will
apply to the Company.

                                BRIDGE FINANCINGS

   
         In order to fund its continuing operations, the Company completed two
Bridge Financings, one in August 1994 ("1994 Bridge Financing") and one in April
1995 ("1995 Bridge Financing"). In connection with the 1994 Bridge Financing,
the Company issued (i) an aggregate of $1,000,000 in principal amount of 9%,
Subordinated Notes ("1994 Notes") and (ii) an aggregate of 500,000 Class A
Warrants to purchase an aggregate of 200,000 shares of the Company's Common
Stock exercisable at $3.75 until November 2, 2000 (the "Class A Warrants," of
which 300,000 Class A Warrants are outstanding as of April 5, 1999 to purchase
120,000 shares of Common Stock). In connection with the 1995 Bridge Financing,
the Company issued (i) an aggregate of $2,037,500 in principal amount of 9%
Subordinated Notes ("1995 Notes," and together with the 1994 Notes, the "Bridge
Notes") and (ii) an aggregate of 1,018,750 Class B Warrants to purchase an
aggregate of 407,500 shares of the Company's Common Stock exercisable at $4.375
until November 2, 2000 (the "Class B Warrants," of which 482,720 are outstanding
as of April 5, 1999 to purchase 193,088 shares of Common Stock, and together
with the Class A Warrants, the " Bridge Warrants"). The Company repaid the 1994
Notes and 1995 Notes in 1995, including $400,000 of the Notes which were past
due, from the net proceeds of the IPO. In addition, warrants were issued to the
placement agent of the 1994 Bridge Financing, as described below.
    

         In connection with the 1994 Bridge Financing, Blair acted as placement
agent. In consideration of these services, the Company paid to Blair a fee equal
to $120,000, a non-accountable expense allowance of $10,000 and an option to
acquire warrants to purchase up to an aggregate of 66,667 shares of the
Company's Common Stock at an exercise price of $3.75 per share. In addition, in
connection with the 1994 Bridge Financing, the Company executed a merger and
acquisition agreement ("M/A Agreement") with Blair and granted Blair a right of
first refusal with respect to offerings of securities of the Company. In
anticipation of the 1995 Bridge Financing, all such rights of Blair with respect
to the M/A Agreement and right of first refusal were canceled in consideration
of the payment by the Company to Blair of $50,000. In addition, pursuant to a
consulting agreement with the Company, Blair rendered investment banking advice
and assistance in structuring the 1995 Bridge Financing. In consideration of
these services, the Company granted Blair an option to acquire warrants equaling
33-1/3% of all warrants issued in connection with the 1995 Bridge Financing.
Such warrants to purchase an aggregate of 135,833 shares of Common Stock provide
for an exercise price of $3.75 per share. The holders of these warrants issued
to the placement agent of the 1994 Bridge Financing have certain demand and
"piggy-back" registration rights.

         JMA acted as placement agent for the 1995 Bridge Financing and in
consideration thereof received a fee of $203,750 plus a non-accountable expense
allowance of $61,125. In addition, JMA was granted, in connection with its
services as Placement Agent for the 1995 Bridge Financing, a (i) five-year right
of first refusal to act as agent for offerings of securities by the Company and
certain of its shareholders and (ii) merger and acquisition agreement.

         The aggregate net proceeds to the Company from the issuance of its
Bridge Notes and Bridge Warrants were approximately $2,500,000. The Company used
the proceeds from the 1994 Bridge Financing to fund its operations (including
paying for research and development activities, operating expenses and accrued
liabilities, and for officers compensation) and a portion of the expenses of the
1994 Bridge Financing and the 1995 Bridge Financing.


                             1998 PRIVATE PLACEMENT

   
         In April 1998, the Company completed a private placement of 56.3 Units
consisting of an aggregate of 671,026 shares of Common Stock and Class E
Warrants to purchase 335,540 shares of Common Stock (the "Private Placement
Warrants") for a purchase price of $100,000 per Unit pursuant to Section 4(2)
and the provisions of Regulation D promulgated under the Securities Act (the
"1998 Private Placement"). Each Unit consisted of (i) a number of shares
determined by dividing $100,000 by the average closing bid price for the Common
Stock for the 30 consecutive trading days immediately preceding the date of the
respective closing (the "Average Closing Bid Price") and (ii) a number of
Private Placement Warrants to purchase one-half of such number of shares of
Common Stock. Each Private Placement Warrant entitles the holder thereof to
purchase one share of Common Stock of the Company at any time after the closing
until 5:00 p.m. EST on April 2, 2003 at an exercise price equal to 120% of the
Average Closing Bid Price, subject to anti-dilution adjustment in certain
circumstances. The Company filed a registration statement under the Securities
Act, therein registering the shares of Common Stock and the shares issuable upon
the exercise of the Private Placement Warrants in October 1998. Also, the
Company has undertaken to maintain the effectiveness of such registration
statement until the expiration of the Private Placement Warrants, April 2, 2003.
JMA acted as placement agent for the 1998 Private Placement pursuant to a
Placement Agency Agreement, dated March 31, 1998, and in consideration for its
services as such, received a commission equal to 10% of the gross proceeds from
the sale of the Units, a 3% nonaccountable expense allowance and reimbursement
for other costs, including legal expenses relating to the offering. JMA also
received warrants to purchase 20% of the number of Units sold in the 1998
Private Placement, for 134,199 shares of Common Stock at exercise prices ranging
from $8.18 to $9.46, and warrants for 67,101 shares of Common Stock at exercise
prices ranging from $9.816 to $11.352, per share exercisable for a five-year
period, commencing April 2, 1998 until April 2, 2003. The Company used the
proceeds of the 1998 Private Placement for working capital, including research
and development. See "-Description of Securities-Class E Warrants."
    


                         SHARES ELIGIBLE FOR FUTURE SALE

   
         The Company has 10,290,380 shares of Common Stock outstanding. Holders
of the Class C and Class D Warrants will be entitled to purchase an aggregate of
6,523,073 additional shares of Common Stock upon the exercise of such Warrants
until November 2, 2000, provided that the Company satisfies certain securities
registration and qualification requirements with respect to the securities
underlying such Warrants. All shares of Common Stock purchased upon exercise of
the Warrants will be freely tradeable without restriction under the Securities
Act (provided that such registration and qualification requirements are met),
except for any shares purchased by any person who is or thereby becomes an
"affiliate" of the Company, which shares may be subject to the resale
limitations contained in Rule 144 promulgated under the Securities Act.
    

         Up to 800,000 additional shares of Common Stock, may be purchased by
the Underwriters in connection with the IPO through the exercise of the IPO Unit
Purchase Option and the warrants included therein (including the Class D
Warrants issuable upon exercise of the Class C Warrants included therein)
(collectively, the "Option Warrants"). Any and all shares of Common Stock
purchased upon exercise of the Option Warrants may be freely tradeable, provided
that the Company satisfies certain securities registration and qualification
requirements in accordance with the terms of the IPO Unit Purchase Option.

         A significant number of shares of Common Stock and shares of Common
Stock issuable upon the conversation of the Series A Preferred Stock, none of
which are being offered hereby, are "restricted securities" within the meaning
of Rule 144 promulgated under




                                       53

<PAGE>   56

the Securities Act and, if held for at least one year (which a substantial
portion, if not all, of the shares are), may be eligible for sale in the public
market in reliance upon Rule 144 following the expiration of such period.

         In general, under Rule 144, a person (or persons whose shares are
aggregated), including a person who may be deemed to be an "affiliate" of the
Company as that term is defined under the Securities Act, will be entitled to
sell within any three-month period a number of shares beneficially owned for at
least one year that does not exceed the greater of (i) one (1%) percent of the
then outstanding shares of Common Stock, or (ii) the average weekly trading
volume in the Common Stock during the four calendar weeks preceding such sale.
Sales under Rule 144 are also subject to certain requirements as to the manner
of sale, notice and the availability of current public information about the
Company. Moreover, a person who is not deemed to have been an affiliate of the
Company during the 90 days preceding a sale by such person, and who has
beneficially owned shares of Common Stock for at least two years, may sell such
shares without regard to the volume, manner of sale or notice requirements of
Rule 144.

         The Company cannot predict the effect, if any, that sales of Common
Stock pursuant to Rule 144 or otherwise, or the availability of such shares for
sale, will have on the market price prevailing from time to time. Nevertheless,
sales by the existing stockholders of substantial amounts of Common Stock in
the public market could adversely affect prevailing market prices for the
Common Stock. In addition, the availability for sale of a substantial amount of
Common Stock acquired through the exercise of the Warrants and the IPO Unit
Purchase Option could adversely affect prevailing market prices for the Common
Stock.




                              PLAN OF DISTRIBUTION

         The securities offered hereby are being offered directly by the Company
pursuant to the terms of the Warrants. No underwriter is being utilized in
connection with this offering.

         The Company has agreed to pay JMA a fee (the "Solicitation Fee") equal
to 5% of the aggregate exercise price of all Warrants exercised, provided that
(i) the market price of the Common Stock on the date that the Warrants are
exercised is greater than the Warrant exercise price; (ii) the exercise of the
Warrants was solicited by JMA or its representative or agent and the
warrantholder designates in writing that the exercise was solicited thereby;
(iii) the Warrants are not held in a discretionary account; (iv) disclosure of
this compensation arrangement is made by JMA at the time of the exercise of the
Warrants; and (v) the solicitation of the exercise of the Warrants was not in
violation of Rule 10b-6 promulgated under the Exchange Act. JMA will generally
be prohibited, pursuant to Rule 10b-6, from engaging in market-making activities
with regard to the Company's securities for a period specified by Rule 10b-6
promulgated under the Exchange Act prior to any solicitation of the exercise of
Warrants until the termination of such solicitation. Accordingly, JMA may be
unable to provide a market for the Company's securities during certain periods
while the Warrants are exercisable.


                                  LEGAL MATTERS

   
         The validity of the securities offered hereby will be passed upon for
the Company by Morrison Cohen Singer & Weinstein, LLP, New York, New York. A

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Stockholders
Cytoclonal Pharmaceutics Inc.
Dallas, Texas
 
     We have audited the accompanying balance sheets of Cytoclonal Pharmaceutics
Inc. as of December 31, 1998 and 1997, and the related statements of operations,
changes in stockholders' equity and cash flows for each of the years in the
three-year period ended December 31, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements enumerated above present fairly,
in all material respects, the financial position of Cytoclonal Pharmaceutics
Inc. as of December 31, 1998 and 1997, and results of its operations and its
cash flows for each of the years in the three-year period ended December 31,
1998, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1998 AND 1997
 
NOTE A -- THE COMPANY
 
     Cytoclonal Pharmaceutics Inc. (the "Company") is involved in the research
and development of various therapeutic and diagnostic pharmaceutical products
for the prevention of cancer, viral and immune diseases. Through June 1998, the
Company was in the development stage and its efforts had been principally
devoted to research and development, capital formation and organizational
development.
 
NOTE B -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
[1]  EQUIPMENT:
 
     Equipment is stated at cost. Depreciation is provided using the
straight-line method over the estimated useful lives of the assets which range
from five to seven years. Leasehold improvements are amortized over the lesser
of the economic useful life of the improvement or term of the lease whichever is
shorter.
 
[2]  PATENT RIGHTS AND COSTS:
 
     Purchased patents, which were acquired in October 1991, are stated at cost
and are being amortized using the straight-line method over the 17 year life of
the patents.
 
[3]  RESEARCH AND DEVELOPMENT:
 
     Research and development costs are charged to expense as incurred.
 
[4]  LOSS PER COMMON SHARE:
 
     Basic and diluted loss per common share is based on the net loss increased
by dividends on preferred stock ($187,000 in 1998, $234,000 in 1997 and $307,000
in 1996) divided by the weighted average number of common shares outstanding
during the year. No effect has been given to outstanding options, warrants or
convertible preferred stock in the diluted computation as their effect would be
antidilutive.
 
[5]  CASH AND CASH EQUIVALENTS AND CONCENTRATION OF CREDIT RISK:
 
     Financial instruments which potentially subject the Company to
concentration of credit risk consist of cash equivalents which amount to
$6,826,000 at December 31, 1998. Cash equivalents consist of interest bearing
cash deposits placed with a single financial institution. The Company considers
all highly liquid short-term investments purchased with a maturity of three
months or less to be cash equivalents.
 
[6]  STOCK-BASED COMPENSATION:
 
     The Company has elected to continue to account for its stock-based
compensation plans using the intrinsic value method prescribed by Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees"
("APB No. 25"). Under the provisions of APB No. 25, compensation cost for stock
options is measured as the excess, if any, of the quoted market price of the
Company's common stock at the date of the grant over the amount an employee must
pay to acquire the stock.
 
[7]  FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     The carrying value of cash equivalents, accounts payable and accrued
expenses approximates their fair value due to the short period to maturity of
these instruments. It is not practicable to estimate the fair value of royalties
payable due to repayment terms varying based on sales of products by the Company
and the lack of such sales at December 31, 1998.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                           DECEMBER 31, 1998 AND 1997
 
[8]  USE OF ESTIMATES:
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
[9]  REVENUE RECOGNITION:
 
     Revenue from research support agreements is recognized as the expenses for
research and development activities performed under the terms of the agreements
are incurred. Revenue from nonrefundable license fees is recognized upon signing
the agreement. Revenue resulting from the achievement of milestones is
recognized when the milestone is achieved. Amounts received in advance of
services to be performed are recorded as deferred revenue.
 
NOTE C -- ROYALTIES PAYABLE
 
     On October 10, 1991, the Company entered into an agreement to acquire
certain patent rights, technology and know-how (the "Technology") from Wadley
Technologies, Inc. ("Wadtech") for the fixed sum of $1,250,000 and ongoing
royalties.
 
     The agreement provides for the payment of royalties of up to 6.25% of gross
selling price of products incorporating the Technology and up to 50% of all
compensation received by the Company for sales by sublicensees of any products
covered by the Technology, which will be applied to reducing the fixed sum of
$1,250,000, until the fixed sum is paid. Thereafter, the agreement provides for
the payment of royalties of up to 3.75% of gross selling price of products
incorporating the Technology and up to 50% of all compensation received by the
Company for sales by sublicensees of any products covered by the Technology. The
agreement also provides for minimum annual royalty payments of $31,250, $62,500
and $125,000 payable quarterly during each twelve-month period beginning October
1, 1996, 1997 and 1998, respectively. Thereafter, during each twelve-month
period beginning October 1, 1999, the agreement provides for minimum annual
royalty payments of $125,000 payable quarterly. As of December 31, 1998, the
Company has made payments of $93,750.
 
     The Company granted Wadtech a security interest in the Technology until the
fixed sum is paid. The agreement continues for 99 years from October 10, 1991
and the Company has the option to terminate the agreement without cause on three
months notice to Wadtech.
 
NOTE D -- LICENSE AND RESEARCH AGREEMENT
 
     In June 1998, the Company entered into a license and research agreement
with Bristol Myers Squibb ("BMS") applicable to two technologies, which are
being sublicensed by the Company to BMS, related to production of Paclitaxel,
the active ingredient in BMS's largest selling cancer product. The agreement,
which is for a term of ten years, subject to earlier termination at the option
of BMS, includes fees, milestone payments, research and development support and
minimum and sales-based royalties to be paid to the Company. During the year
ended December 31, 1998, revenues of $1,183,000 were earned under the agreement.

(a) See Notes I[3] and I[4]
 
     The Class C and Class D warrants are subject to redemption at $.05 per
warrant on 30 days prior written notice provided the average of the closing bid
prices of the common stock for any period of 30 consecutive business days ending
within 15 business days of the date on which the notice of redemption is given
shall have exceeded $9.10 per share for redemption of the Class C warrants and
$12.25 per share for redemption of the Class D warrants.
 
     Each Class C warrant entitles the holder to purchase a unit consisting of
one share of common stock and one redeemable Class D detachable warrant. Each
Class D warrant entitles the holder to purchase one share of common stock. The 
Class D Warrants reflected in the above table include 2,006,073 warrants which 
are issuable upon the exercise of the outstanding Class C Warrants.
 
     In addition to the above, options are outstanding to purchase 506,250
warrants at $.10 per warrant. These warrants are exerciseable into an aggregate
of 202,500 shares of common stock through November 2000 at a price of $3.75 per
share.
 
     In connection with its initial public offering, the Company sold to the
underwriter, at a nominal amount, a unit purchase option to purchase up to an
aggregate of 200,000 additional units at $8.25 per unit. The units purchasable
upon exercise of the unit purchase option are comprised of one share of common
stock, one Class C warrant and one Class D warrant. The warrants included
therein are not subject to redemption by the Company. These units became
exerciseable November 1998 for a two-year period.
 
     See Note I[5] for unit purchase option issued in connection with private
placement in 1998.
 
[4]  STOCK OPTIONS:

     The weighted average fair value at date of grant for options granted during
1998, 1997 and 1996 was $3.27, $2.34 and $2.16 per option, respectively. The
fair value of options at date of grant was estimated using the Black-Scholes
option pricing model utilizing the following assumptions:

     Had the Company elected to recognize compensation cost based on the fair
     value of the options at the date of grant as prescribed by Statement of
     Financial Accounting Standards No. 123, "Accounting for Stock-Based
     Compensation," net loss in 1998, 1997 and 1996 would have been $3,199,000,
     $3,593,000 and $3,195,000 or $.35, $.46 and $.46 per share, respectively.
 
NOTE H -- INCOME TAXES
 
     At December 31, 1998, the Company had approximately $16,700,000 of net
operating loss carryforwards for federal income tax purposes which expire
through 2018.
 
     At December 31, 1998, the Company has a deferred tax asset of approximately
$5,900,000 representing the benefits of its net operating loss carryforward and
certain expenses not currently deductible. The Company's deferred tax asset has
been fully reserved by a valuation allowance since realization of its benefit is
uncertain. The difference between the statutory tax rate of 34% and the
Company's effective tax rate of 0% is due to the increase in the valuation
allowance of $1,000,000 (1998), $1,000,000 (1997) and $1,000,000 (1996). The
Company's ability to utilize its net operating loss carryforwards may be subject
to an annual limitation in future periods pursuant to Section 382 of the
Internal Revenue Code of 1986, as amended.
 
NOTE I -- COMMITMENTS AND OTHER MATTERS
 
[1]  LEASES:
 
     The Company occupies office and laboratory space under two leases expiring

royalties on net sublicense fees received from sublicensing the technology. The
Company also agreed to reimburse the employee for certain expenses and to assume
liability for certain payments upon the realization of profit from the
technology.
 
[3]  CONSULTING AGREEMENTS:
 
     During 1996, the Company entered into an agreement with a consulting firm
whereby the Company has agreed to pay a fee of $3,000 per month, until the
agreement is terminated by either party and to grant warrants to purchase 75,000
shares of common stock at $4.25 per share in return for financial advisory
services. The warrants will be granted and become exercisable in the event a
transaction introduced to the Company by the consulting firm is consummated, at
which time the Company will record a noncash charge representing the fair value
of the warrants.
 
     In August 1998, the Company entered into an agreement with a consulting
firm whereby the Company has agreed to pay a fee of $35,000 in return for
financial advisory services. In connection with the agreement, the Company
issued five-year warrants to purchase 75,000 shares of common stock. Warrants
for 50,000 shares vest on December 31, 1998 of which 37,500 have an exercise
price of $7.00 per share and 12,500 have an exercise price of $8.00 per share.
The Company determined the fair value of these warrants to be approximately
$181,000 which was charged to operations. The remaining 25,000 warrants have an
exercise price of $9.00 per share and vest only if a transaction introduced to
the Company by the consulting firm is consummated, at which time the Company
will record a noncash charge representing the fair value of the warrants.

     (a) Agreements With Research and Development Institute, Inc. ("RDI"):
 
          During June 1993, the Company entered into a research and license
     agreement with RDI of Montana State University pursuant to which the
     Company finances and RDI conducts research and development at Montana State
     University in the field of taxol producing organisms. In connection with
     the agreement, RDI has granted the Company an exclusive license and
     licensing rights to its patents and know-how throughout the world to
     develop and market products relating to the technology.
 
          The Company has agreed to finance research to be conducted under the
     agreement and paid RDI an aggregate fixed fee of $250,000 per annum for
     four years commencing in 1993. In July 1998, the Company agreed to finance
     research for an additional year for $250,000. In addition, the Company has
     agreed to pay RDI royalties of up to 6% of net sales of products derived
     under the agreement with minimum royalty payments as follows: $25,000 in
     June 1994, $50,000 in June 1995, $75,000 in June 1996 and $100,000 in June
     1997 and annually thereafter. The agreement was amended during May 1998 to
     require the Company to pay a percentage of royalties received with respect
     to the manufacture, use or sale of the inventions by sublicensees and a
     percentage of all up-front, milestone, and royalty payments which may be
     received under the agreement with Bristol-Myers Squibb (see Note D). Under
     the agreement, the minimum royalties shall be credited against royalties
     paid in connection with the amendment.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                           DECEMBER 31, 1998 AND 1997
 
          During August 1998, the Company entered into an additional license
     agreement with RDI whereby RDI has granted the Company an exclusive license
     and licensing rights to its patents and know-how throughout the world to
     research, develop and market products developed with or from the
     pestalotiopsis microspora organism. The Company paid a license fee of
     $10,000 and agreed to pay sales-based royalties.
 
     (b) Agreements With Pestka Biomedical Laboratories, Inc. ("Pestka"):
 
          In September 1992, the Company formed a corporate joint venture with
     Pestka for the purpose of developing, manufacturing and marketing a
     therapeutic drug for blood related cancers such as leukemia and lymphomas.
     The agreement provides for the Company to contribute $233,000, which was
     paid during 1992, and certain technology and for Pestka to grant the joint
     venture an exclusive, worldwide license to certain patents and proprietary
     rights. Under a related agreement, Pestka agreed to perform certain
     research and development, as defined, for the joint venture, for $233,000.
     The stockholders of Pestka purchased 20,000 shares of the Company's common
     stock for a price of $1.65 per share. The investment in the joint venture
     is accounted for on the equity method. As of December 31, 1997, the
     Company's share of cumulative losses from the venture equaled its
     investment and accordingly, the investment has no carrying amount in the
     accompanying balance sheets. The equity in loss of joint venture, included
     in research and development costs, was $0 for the year ended December 31,
     1998, $16,000 for the year ended December 31, 1997 and $23,000 for the year
     ended December 31, 1996. The venture is presently inactive, and the Company
     has no further obligation to fund the venture.
 
     (c) Agreements with Washington State University Research Foundation
("WSURF"):
 
          In July 1996, the Company entered into an agreement with WSURF whereby
     the Company received an exclusive, world-wide license to use and/or
     sublicense patented technology or prospective patented technology (the
     "WSURF Technology"). In June 1998, the agreement was amended to cover
     additional patents. The Company was required to pay WSURF license fees of
     $7,500 per year commencing on July 1, 1997. The agreement was amended
     during May 1998 to require the Company to pay a percentage of royalties
     received with respect to the manufacture, use or sale of the inventions by
     sublicensees and a percentage of all up-front, milestone and royalty
     payments which may be received under the agreement with Bristol Myers
     Squibb (see Note D). In addition, the Company agreed to pay minimum
     royalties of $50,000 per year payable on July 1, 1999, $75,000 payable on
     July 1, 2000, and $100,000 payable on July 1, 2001 and annually thereafter.
     This agreement will remain in effect until the last to expire of the
     patents licensed under the WSURF Technology, subject to termination by
     either party. In conjunction with this agreement, the Company granted WSURF
     warrants to purchase 36,000 shares of common stock at $4.25 per share. An
     aggregate of 12,000 warrants per annum are exercisable commencing July 1999
     and expire July 2002. The Company determined the fair value of these
     warrants to be approximately $42,000 which was charged to research and
     development in 1996.
 
          In July 1996, the Company entered into a research agreement with WSURF
     for research to be conducted on behalf of the Company. In August 1998, the
     agreement was extended through July 2000 providing for additional funding
     of $500,000. As of December 31, 1998, the Company has incurred
     approximately $104,000 of research costs under the agreement.
 
     (d) Agreements with Regents of the University of California:
 
          In February 1996, the Company entered into two license agreements
     ("Agreements") with the Regents of the University of California, granting
     to the Company exclusive rights to certain technology and patent rights.
     Pursuant to the Agreements, the Company paid license fees of $10,000 and
     $15,000 upon issuance of the patents. In addition, the Company must pay a
     yearly license maintenance fee of $8,000, increasing by $4,000 per year

                                     PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The Certificate of Incorporation and By-Laws of the Registrant provides
that the Company shall indemnify any person to the full extent permitted by the
Delaware General Corporation Law (the "GCL"). Section 145 of the GCL, relating
to indemnification, is hereby incorporated herein by reference.

          Insofar as indemnification for liabilities under the Securities Act
may be permitted to Directors, officers or controlling persons of the Company
pursuant to the Company's By-Laws and the Delaware General Corporation Law, the
Company has been informed 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.

          The Company's Certificate of Incorporation includes certain
provisions permitted pursuant to Delaware law whereby officers and Directors of
the Company are to be indemnified against certain liabilities. The Company's
Restated Certificate of Incorporation also limits, to the fullest extent
permitted by Delaware law, a director's liability for monetary damages for
breach of fiduciary duty, including gross negligence, except liability for (i)
breach of the director's duty of loyalty, (ii) acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of the
law, (iii) the unlawful payment of a dividend or unlawful stock purchase or
redemption and (iv) any transaction from which the director derives an improper
personal benefit. Delaware law does not eliminate a director's duty of care and
this provision has no effect on the availability of equitable remedies such as
injunction or rescission based upon a director's breach of the duty of care. In
addition, the Company has obtained an insurance policy providing coverage for
certain liabilities of its officers and Directors.

          In accordance with Section 102(a)(7) of the GCL, the Certificate of
Incorporation of the Registrant eliminates the personal liability of directors
to the Company or its stockholders for monetary damages for breach of fiduciary
duty as a director with certain limited exceptions set forth in Section
102(a)(7).



ITEM 25.  OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

ITEM 26. RECENT SALES OF UNREGISTERED SECURITIES

         In the three years preceding the filing of this Registration Statement,
the Company has issued the following unregistered securities.

   
         In July 1996, the Company issued WSURF a six year warrant in connection
with the execution of the Company's license agreement with WSURF. Such warrant
entitles WSURF to acquire an aggregate of 36,000 shares of the Company's Common
Stock at an exercise price of $4.25 per share. One third of the warrants may be
exercised after each of July 7, 1999, July 7, 2000 and July 2, 2001. The warrant
was issued pursuant to the exemption afforded by Section 4(2) promulgated under
the Securities Act based on the fact that the issuance was to a single entity
not involving a public offering.
    

         In January 1997, the Company issued 122,788 shares of Series A
Preferred Stock as full payment of the dividend due on the Series A Preferred
Stock for the year ended December 31, 1996 to the holders of such preferred
stock. Such issuance was pursuant to Section 3(a)(9) promulgated under the
Securities Act based on the fact that it involved an exchange by the issuer
exclusively with its existing security-holders and no commission or other
remuneration was paid or given directly or indirectly for soliciting such
exchange.

         In February and September 1997, the Company granted options to purchase
10,000 and 40,000 shares of Common Stock at exercise prices of $4.38 and $4.31
per share, respectively, as compensation for professional services. The options
were granted pursuant to the exemption afforded by Section 4(2) promulgated
under the Securities Act based on the fact that the issuance was to a single
entity not involving a public offering.

         In January and March 1998, the Company issued an aggregate of 94,680
shares of Series A Preferred Stock as full payment of the dividend due on the
Series A Preferred Stock for the year ended December 31, 1997 to the holders of
such preferred stock. Such issuance was pursuant to Section 3(a)(9) promulgated
under the Securities Act based on the fact that it involved an exchange by the
issuer exclusively with its existing security-holders and no commission or other
remuneration was paid or given directly or indirectly for soliciting such
exchange.

   
         In April 1998, the Company completed a private placement of 671,026
shares of Common Stock and 335,540 Common Stock Purchase Class E Warrants to
purchase an equal amount of shares of Common Stock pursuant to Section 4(2) and
the provisions of Regulation D promulgated under the Securities Act. In
connection with such private placement, the Company issued to an option to the
placement agent to purchase 134,207 shares of Common Stock and warrants to
purchase 67,108 shares of Common Stock pursuant to Section 4(2) and the
provisions of Regulation D promulgated under the Securities Act.


         In January 1999, the Company granted 25,000 shares of Common Stock
pursuant to a three-year employment agreement between the Company and its Vice
President of Drug Design in consideration for such individual's assignment of
technology to the Company. The shares of Common Stock were granted pursuant to
the exemption afforded by Section 4(2) promulgated under the Securities Act
based on the fact that the issuance was to a single individual non involving a
public offering.

         On October 8, 1998, the Company granted options under the Company's
1996 Stock Option Plan, as amended, to purchase 265,000 shares of Common Stock
at an exercise price equal to $4.75 per share, the fair market value of the
Company's Common Stock on such date, to certain of its executive officers,
directors and employees and counsel in consideration for professional services
rendered The Company granted such options pursuant to the exemption afforded by
Section 4(2) promulgated under the Securities Act based on the fact that the
grant didn't not involve a public offering.

         In January 1999, the Company issued 74,648 shares of Series A Preferred
Stock as full payment of the dividend due on the Series A Preferred Stock for
the year ended December 31, 1998 to the holders of such preferred stock. Such
issuance was pursuant to Section 3(a)(9) promulgated under the Securities Act
based on the fact that it involved an exchange by the issuer exclusively with
its existing security-holders and no commission or other remuneration was paid
or given directly or soliciting such exchange.

ITEM 28. UNDERTAKINGS

     UNDERTAKINGS REQUIRED BY REGULATION S-B, ITEM 512(A).

     The undersigned registrant hereby undertakes to:

         (1)      File, during any period in which it offers or sells
securities, a post-effective amendment to this registration statement to:

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

                  (ii)     Reflect in the prospectus any facts or events which,
                           individually or together, represent a fundamental
                           change in the information in the registration
                           statement; and

                  (iii)    Include any additional or changed material
                           information on the plan of distribution.

         (2)      For determining liability under the Securities Act, treat each
post-effective amendment as a new registration statement of the securities
offered, and the offering of the securities at that time to be the initial bona
fide offering.

         (3)      File a post-effective amendment to remove from registration
any of the securities that remain unsold at the end of the offering.

         UNDERTAKING REQUIRED BY REGULATION S-B, ITEM 512(E).

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers or controlling persons of
the registrant pursuant to any arrangement, provision 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 Securities
Act and will be governed by the final adjudication of such issue.

                        (File No. 33-91802)

Dear Sirs:

         We hereby refer to Post-Effective Amendment No. 5 to the Registration
Statement on Form SB-2 (Reg. No. 33-91802) (the "Registration Statement") filed
by you, Cytoclonal Pharmaceutics Inc., a Delaware corporation (the "Company"),
with the Securities and Exchange Commission pursuant to the Securities Act of
1933, as amended, thereby registering an aggregate amount of (i) 6,523,073
shares of common stock, $.01 par value per share (the "Common Stock"), of the
Company and (ii) 2,006,073 Redeemable Class D Warrants (the "Class D Warrants")
issued in connection with the Company's initial public offering completed in
November 1995 (the "IPO"). The 6,523,073 shares of Common Stock referenced in
item (i) above consists of (a) 2,006,073 shares of Common Stock issuable upon
the exercise of the Class C Warrants (the "Class C Warrants") at an exercise
price of $6.50 until November 2, 2000 (the "Expiration Date") issued in
connection with the IPO (the "Class C Warrant Shares"), (b) 2,006,073 shares of
Common Stock issuable upon the exercise of the Class D Warrants underlying the
Class C Warrants (the "Underlying Class D Warrants") at an exercise price of
$8.75 until the Expiration Date (the "Underlying Class D Warrants Shares") and
(c) 2,510,927 shares of Common Stock issuable upon the exercise of the Class D
Warrants at an exercise price of $8.75 until the Expiration Date (the "Class D
Warrant Shares").
    

         We have examined and are familiar with originals, or copies certified
or otherwise identified to our satisfaction, of such corporate records of the
Company, certificates of officers of the Company and of public officials and
such other documents as we have deemed appropriate as a basis for the opinions
expressed below.

         Based upon the foregoing, we are of the opinion that:

                  1.       The Underlying Class D Warrants and Class D Warrants
                           have been duly and validly authorized and when sold,
                           paid for and issued as contemplated by the
                           Registration Statement, will be duly and validly
                           issued and fully paid and nonassessable.

                  2.       The Class C Warrant Shares, Underlying Class D
                           Warrant Shares and the Class D Warrants Shares have
                           been duly and validly authorized and when sold, paid
                           for, and issued upon exercise of the respective
                           Warrants in accordance with the terms of such
                           Warrants, will be duly and validly issued and fully
                           paid and nonassessable.

         We hereby consent to the use of this opinion in the above-mentioned
Registration Statement and to the reference to our name under the heading
"Legal Matters" in the Prospectus constituting a part of such Registration
Statement.

                                   Very truly yours,
