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 Common Stock. 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 our 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 and breast cancers. In addition, Paclitaxel has
shown potential in treating refractory non-small cell lung cancer and certain
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 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. We are also focusing on possible Paclitaxel treatment of
Polycystic Kidney Disease, our gene discovery program for the early diagnosis
and treatment of lung cancer and our vaccine program. 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 License Agreements

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

3


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 them 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(TM). 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 the Research & Development Institute, Inc. at Montana State University
("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 Notice of Allowance of patent claims was
received in June 1998. 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") allowed such patent in August 1997. 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. For the six month period ended June 30, 1998, we, for the first
time, generated $789,000 in revenues from the $1,250,000 we had received from
Bristol-Myers Squibb with the remaining $461,000 of the $1,250,000 to be applied
to the third and fourth quarters of 1998. We, however, have experienced
operating losses of $2,319,000 for the fiscal year ended December 31, 1995;
$3,106,000 for the fiscal year ended December 31, 1996; and $3,357,000 for the
fiscal year ended December 31, 1997. We have also experienced operating losses
of $1,575,000 for the six month period ended June 30, 1997 and $1,044,000 for
the six month period ended June 30, 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."

RISK FACTORS

You should carefully consider the following factors and other information
in this prospectus before deciding to invest in shares of the Company's Common
Stock being offered by the Selling Stockholders.

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 $16,063,000 as of the quarter ended June 30, 1998 (which
has not been audited by our auditors). 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
six month period ended June 30, 1998 (which has not been audited by our
auditors) shows net losses of $959,000, which means a loss of $.11 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.

From our formation in 1991 until the six month period ended June 30, 1998,
we were considered to be a "development stage" company, which is what they call
companies which have not yet generated any sales revenues. However, because we
had revenues of $789,000 in the six month period ended June 30, 1998 from 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 the third
quarter of 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 and our agreement with RDI. We cannot
say with any certainty that required financing will be available to us on terms
favorable, 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. If we enter into additional agreements, we will rely upon the
other parties to honor their responsibilities and perform their obligations
under the agreements. In March 1992, we entered into a collaborative research,
development and license agreement (the "Enzon Agreement") with Enzon, Inc., a
research, development and manufacturing company which had developed certain
pharmaceutical products and technology relating to polypeptides and antigen
binding protein products ("Enzon"). Pursuant to the Enzon Agreement, we granted
Enzon a license to develop certain protein strains using certain of our


7


technology until March 2005. Besides the Enzon Agreement and our agreement with
RDI, we have entered into several other research and license agreements, and we
are continually seeking to enter into additional arrangements with other
companies and institutions. However, 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 Competition; and -Our
Uncertain Ability to Protect Our Technology."

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. 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.

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."


8


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 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 $231,563 of the $285,240 which we owe them as of June 30, 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


9


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 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


10


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 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 receptive
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


11


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 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. If we develop fungal Paclitaxel and
obtain regulatory approval of it, we intend to contract outside parties to
manufacture it for us. We cannot say with any certainty whether we will be able
to enter into any arrangements with 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."

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, as well as
our senior scientists, Susan L. Berent, Ph.D., Hakim Labidi, Ph.D., Rajinder S.
Sidhu, Ph.D. and Richard M. Torczynski, Ph.D. As of October 6, 1998, we had 16
full-time employees, 13 of whom are engaged directly in research and development
activities and 3 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


12


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.

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.

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 49.5% of our
outstanding shares of Common Stock, which represents approximately 46.7% 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 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,


13


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 10.2%, respectively, of the outstanding
shares of Common Stock, which represents approximately 10.9% and 9.6%,
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
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


14


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 11,491,316 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 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)


15


764,003 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 and the 520,588 shares of Common Stock
issuable upon the exercise of such warrants; (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 873,700 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) 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 (v) granted the holders of options and
warrants to purchase a total of 175,000 shares of Common Stock certain
"piggyback" 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


16


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. 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 1,663,143 shares of Series A Preferred Stock,
of which 916,279 have been converted into Common Stock as of October 21, 1998,
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. Payment-in-kind
dividends are when you give the stockholder who is entitled to receive a
dividend of more stock instead of cash. 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."

USE OF PROCEEDS

We will not receive any of the proceeds from the Selling Stockholders' sale
of their Common Stock. However, certain of the Selling Stockholders hold
warrants exercisable for Common Stock. We will receive the proceeds when those
Selling Stockholders exercise their warrants. We will use the proceeds we
receive when the Selling Stockholders exercise their warrants for research and
development and general corporate purposes.

DESCRIPTION OF SECURITIES

Besides the shares held by JMA and Synergy, the shares of Common Stock
being offered pursuant to this prospectus were purchased by the Selling
Stockholders in a private placement of 56.3 Units we completed in April 1998
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 Selling Stockholder 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 Selling Stockholder purchased was equal to one-half the number of
shares of Common Stock each stockholder 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). See "Risk Factors--Possible
Restriction on 'Market Making' Activities in the Company's Securities;
Illiquidity; and Selling Stockholders."

The 201,300 shares of Common Stock being offered by this prospectus by JMA
are issuable pursuant to a unit purchase option we granted to 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 75,000 shares of Common Stock being offered by this prospectus by
Synergy are issuable pursuant to warrants we issued to Synergy for its financial
and advisory services under a consulting agreement, dated August 7, 1998, we
have with Synergy. Of the warrants issuable for 75,000 shares of Common Stock,
(i) 50,000 shall vest on December 31, 1998 or upon our retention of an
investment banking firm introduced to us by Synergy (an "Introduced Firm"),
whichever is sooner, and (ii) 25,000 shall vest only upon our retention of an
Introduced Firm. 37,500 of the warrants have an exercise price equal to $7.00
per share of Common Stock. 12,500 of the warrants have an exercise price
equal to $8.00 per share; and the remaining 25,000 warrants have an exercise
price equal to $9.00 per share.

PLAN OF DISTRIBUTION

This prospectus may be used from time to time by the Selling Stockholders
to sell their shares of Common Stock registered in this prospectus in
transactions in which they are or may be deemed to be underwriters within the
meaning of the Securities Act. The Selling Stockholders may also sell their
shares of Common Stock being registered in this prospectus to or through brokers
or dealers who may act solely as agent, or may acquire shares as principal. The
distribution of the shares of Common Stock may be effected in one or more
transactions that may take place on the Nasdaq SmallCap Market System, ordinary
broker's transactions, privately negotiated transactions or through sales to one
or more broker-dealers for resale of such securities as principals, at market
prices prevailing at the time of sale, at prices related to such prevailing
market prices or at negotiated prices. Usual and customary or specifically
negotiated brokerage fees or commissions may be paid by these holders in
connection with such sales. In connection with such sales, the Selling
Stockholders and any participating brokers or dealers may be deemed
"underwriters" as such term is defined in the Securities Act. See "Risk
Factors-Current Prospectus and State Registration Required to Resell Common
Stock."

JMA is a Selling Stockholder and beneficially owns 201,300 of the shares of
Common Stock included in this offering. JMA is also a market-maker in our

Placement, JMA received a commission of 10% of the gross proceeds, as well as 3%
non-accountable expense allowance and reimbursement for other costs, including
legal expenses relating to the 1998 Private Placement. Also, for its services,
we issued JMA five-year warrants to acquire 20% of the number of securities
bought in the 1998 Private Placement which equals 201,300 of the shares of
Common Stock being registered in this Prospectus. See "Risk Factors--Current

Item 15. 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).
