PROSPECTUS
TEXAS BIOTECHNOLOGY CORPORATION
150,035 Shares
Common Stock
This Prospectus relates to 150,035 shares (the "Shares") of Common Stock, par
value $.005 per share (the "Common Stock"), of Texas Biotechnology Corporation,
a Delaware corporation (the "Company"), which Shares will be offered for resale
from time to time by certain stockholders of the Company (the "Selling
Stockholders"). The Shares include: (i) 36,399 shares of Common Stock
underlying warrants issued in connection with the Company's private placement
of Common Stock completed in October, 1991, exercisable at $3.50 per share and
expiring on August 1, 1998 (the "1991 Warrants"); and (ii) 113,636 shares of
Common Stock underlying warrants issued in connection with the Company's
private placement of Common Stock completed in October 1996, exercisable at
$4.40 per share and expiring on October 10, 2001 (the "1996 Warrants"; the 1991
Warrants and the 1996 Warrants are herein referred to collectively as the
"Warrants").
Pursuant to this Prospectus, the Shares may be offered by the Selling
Stockholders, or by certain pledgees, donees, transferees or other successors
in interest, from time to time in transactions on the American Stock Exchange,
Inc. ("AMEX"), in privately negotiated transactions, or by a combination of
such methods of sale, at fixed prices that may be changed, at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices or at negotiated prices. The Selling Stockholders may effect such
transactions by selling the Shares to or through broker-dealers, and such
broker-dealers may receive compensation in the form of discounts, concessions
or commissions from the Selling Stockholders or the purchasers of the Shares
for whom such broker-dealers may act as agent or to whom they sell as principal
or both (which compensation to a particular broker-dealer might be in excess of
customary commissions). See "Selling Stockholders" and "Plan of Distribution."
Other methods by which the Shares may be sold include, without
limitation: (i) transactions which involve cross or block trades or any other
transaction permitted by the AMEX, (ii) "at the market" to or through market
makers or into an existing market for the Common Stock, (iii) in other ways not
involving market makers or established trading markets, including direct sales
to purchasers or sales effected through agents, (iv) through transactions in
options or swaps or other derivatives (whether exchange-listed or otherwise),
or (v) any combination of any such methods of sale. The Selling Stockholders
may also enter into option or other transactions with broker-dealers which
require the delivery to such broker dealers of the Common Stock offered hereby,
which Common Stock such broker-dealers may resell pursuant to this Prospectus.
None of the proceeds from the sale of the Shares by the Selling
Stockholders will be received by the Company. However, the Company will
receive an aggregate of $627,394.90 upon exercise of all of the Warrants. The
Company has agreed to bear certain expenses (other than any underwriting
discounts and selling commissions and any fees and disbursements of counsel for
the selling stockholders not specifically provided for by the parties),
estimated to be approximately $12,000, in connection with the registration and
sale of the Shares being offered by the Selling Stockholders. Pursuant to a
Registration Rights Agreement with certain Selling Stockholders, the Company
has agreed to indemnify certain of the Selling Stockholders and each
underwriter against certain liabilities, including certain liabilities under
the Securities Act of 1933, as amended, or will contribute to payments such
Selling Stockholders or underwriters may be required to make in respect of
certain losses, claims, damages or liabilities.
The shares of Common Stock are quoted on the AMEX under the symbol
"TXB." On April 15, 1998, the last reported sale price of the Common Stock was
$6.75 per share.
See "Risk Factors" on pages 3-9 for a discussion of certain factors
that should be considered by prospective investors.

THE COMPANY
Texas Biotechnology Corporation ("TBC" or the "Company") is a
biopharmaceutical company engaged in discovering, developing and
commercializing synthetic small molecule drugs primarily for cardiovascular
indications. TBC's research philosophy is based upon combining its expertise
in vascular biology with its advanced computational chemistry capabilities to
identify and develop small molecule compounds. The Company's research and
development programs are currently focused on inhibitors (also referred to as
antagonists or blockers) of thrombosis, vasospasm/hypertension, vascular
inflammation, vascular proliferative disease, angiogenesis and apoptosis. The
Company has filed a new drug application ("NDA") with the United States
("U.S.") Food and Drug Administration (the "FDA") for its lead product
candidate, NOVASTAN(R) (argatroban) for use as an anticoagulant in patients
with heparin-induced thrombocytopenia ("HIT"). This NDA has been granted
priority review status by the FDA, and a decision on approval from the FDA is
anticipated by the end of the second quarter of 1998. The Company has begun
Phase II clinical trials for TBC 11251 (TBC's lead compound for
vasospasm/hypertension) in congestive heart failure ("CHF") and for TBC 1269
(TBC's lead compound for vascular inflammation) in allergic asthma. TBC has
licensed the U.S. and Canadian rights to NOVASTAN(R) from Mitsubishi Chemical
Corporation ("Mitsubishi"). The Company has entered into a collaboration with
SmithKline Beecham plc ("SmithKline") regarding the commercialization and
development of NOVASTAN(R) and has entered into collaborations with Synthelabo
S.A., the pharmaceutical division of L'Oreal S.A. ("Synthelabo"), and LG
Chemical, Ltd. ("LG Chemical") regarding other TBC compounds. The Company's
principal executive offices are located at 7000 Fannin Street, Suite 1920,
Houston, Texas 77030, and its telephone number is (713) 796-8822. References
to TBC or the Company include its subsidiary, IPI, unless otherwise indicated.
RISK FACTORS
In evaluating the Company and its business, prospective investors
should carefully consider all of the information set forth in this Prospectus
and the documents incorporated herein by reference and should give particular
attention to the following risk factors.
No Assurance of Regulatory Approval; Need for Extensive Clinical Trials
The production and marketing of the Company's products, as well as its
ongoing research and development activities, are subject to regulation by
governmental agencies in the United States ("U.S.") and other countries. Any
drug developed by the Company will be subject to rigorous preclinical and
clinical testing and approval pursuant to regulations administered by the FDA,
comparable agencies in other countries and, to a lesser extent, by state
regulatory authorities. This approval process is likely to take several years
and will involve significant expenditures.
For example, in August 1997, the Company filed with the FDA its NDA
regarding NOVASTAN(R) (a direct thrombin inhibitor that is being developed for
various indications as an anticoagulant alternative to heparin) for use in the
treatment of HIT. The NDA was subsequently granted priority review status. In
October 1997, the FDA accepted the filing, and commenced a further review that
was anticipated to take approximately 6 months regarding final approval of the
NDA. During January 1998, the FDA informed the Company that the review time
was being extended by 90 days and a decision on approval by the FDA's
anticipated by the end of the second quarter of 1998. The FDA's refusal to
approve the NDA on this schedule could significantly impair the Company's plans
to commence marketing of NOVASTAN(R) for use in the treatment of HIT.
The cost to the Company of conducting human clinical trials for any
potential product can vary dramatically based on a number of factors, including
the order and timing of clinical indications pursued and the extent of
development and financial support, if any, from corporate partners. Because of
the intense competition in the cardiovascular market, the Company may have
difficulty obtaining sufficient patient populations or clinician support to
conduct its clinical trials as planned and may have to expend substantial
additional funds to obtain access to such resources, or delay or modify its
plans significantly. There is no assurance that the Company will have
sufficient resources to complete the required regulatory review process or that
the Company could survive the inability to obtain, or delays in obtaining, such
approvals. There can be no assurance that clinical testing of the Company's
products will provide evidence of safety and efficacy in humans, that
regulatory approvals will be granted for any of the Company's products or that
it will be economically feasible to commercialize any products for which
regulatory approvals are granted. Approvals that may be granted will be subject
to continual review, and later discovery of previously unknown problems may
result in restrictions on a product's future use or withdrawal of the product
from the market. Substantial changes in regulatory and reimbursement policy may
affect the Company's research and development expenditures and regulatory
approval of the Company's product candidates.
3
5
Dependence on Strategic Relationships
The Company will rely on strategic relationships with corporate
partners to provide the financing, marketing and technical support and, in
certain cases, the technology necessary to develop and commercialize certain of
its product candidates. TBC has entered into an agreement with Mitsubishi to
license Mitsubishi's rights and technology relating to NOVASTAN(R) (the
"Mitsubishi Agreement") in the U.S. and Canada for specified indications.
Either party may terminate the Mitsubishi Agreement on 60 days notice if the
other party defaults in its material obligations under the agreement, declares
bankruptcy or is insolvent, or if a substantial portion of its property is
subject to levy. Unless terminated sooner pursuant to the above described
termination provisions, the Mitsubishi Agreement expires on the later of
termination of patent rights in a particular country or 20 years after the
first commercial sale of products in a particular country. Under the Mitsubishi
Agreement, TBC has access to an improved formulation patent granted in 1993
which expires in 2010 and a use patent which expires in 2009.
In August 1997, the Company and SmithKline entered into a collaboration
regarding the commercialization and development of NOVASTAN(R) (the "SmithKline
Agreement"). Under the SmithKline Agreement the Company granted an exclusive
sublicense to SmithKline relating to the continued development and
commercialization of NOVASTAN(R). The SmithKline Agreement provides for the
payment of royalties and certain milestone payments upon the completion of
various regulatory filings and receipt of regulatory approvals. The SmithKline
Agreement generally terminates on a country by country basis upon the earlier
of the termination of TBC's rights under the Mitsubishi Agreement, the
expiration of applicable patent rights or, in the case of certain royalty
payments, the commencement of substantial third-party competition. SmithKline
also has the right to terminate the agreement on a country by country basis by
giving TBC at least three months written notice based on a reasonable
determination by SmithKline that the commercial profile of the indication in
question would not justify continued development or marketing in that country.
In addition, either party may terminate the SmithKline Agreement on 60 days
notice if the other party defaults in its obligations under the agreement,
declares bankruptcy or is insolvent.
In October 1994, the Company signed a collaborative agreement with
Synthelabo S.A., the pharmaceutical division of Synthelabo to develop and
market compounds for vascular proliferative disease derived from the Company's
research programs. Synthelabo has the right to terminate the agreement any time
on or after October 15, 1997 for any reason and either party has the right to
terminate the contract for breach of any material obligation. If Synthelabo
exercises this termination right, the license granted to Synthelabo will
terminate and TBC will pay Synthelabo a royalty on net sales of any products
sold in a certain territory (Europe, Middle East, Africa and countries of the
former Soviet Union) for a period of time. In addition, Synthelabo may, at its
option, require that the technology be transferred to and the development
program be conducted by a joint venture owned by TBC and Synthelabo should
TBC's "net worth", as defined in the agreement, be less than $5.0 million as of
the end of any calendar quarter during the term of the agreement.
In October 1996, the Company signed a strategic alliance agreement with
LG Chemical to develop and market compounds derived from the Company's
endothelin receptor and selectin antagonist programs for certain disease
indications in certain territories. LG Chemical has committed to pay $10.7
million in research payments and has the right to terminate future research
payments if TBC fails to meet certain milestones to be established by the
parties in accordance with the agreement.
The Company's success will depend on these and any future strategic
alliances. There can be no assurance that the Company will satisfy the
conditions required to obtain additional milestone payments under the existing
agreements or to prevent these agreements from being terminated, some of which
conditions will not be within the control of the Company. There can be no
assurance that the Company will be able to enter into future strategic
alliances on acceptable terms. The termination of any existing strategic
alliances or the inability to establish additional collaborative arrangements
may limit the Company's ability to develop its technology and may have a
material adverse effect on the Company's business or financial condition.
4
6
Development Stage; Technological Uncertainty
The Company is in a development stage and has not produced or marketed
any material products and, accordingly, has not begun to generate revenues from
the commercialization of its product candidates. To date, the Company's
resources have been dedicated to the research and development of small-molecule
drugs for certain vascular and other indications. The Company has developed
lead compounds in its vasospasm/hypertension, vascular inflammation and
vascular proliferative disease programs. The commercial applications of the
Company's product candidates will require further investment, research,
development, preclinical and clinical testing and regulatory approvals, both
foreign and domestic. There can be no assurance that the Company will be able
to develop, produce at reasonable cost, or market successfully, any of its
product candidates. Further, these product candidates may prove to have
undesirable and unintended side effects and, in some cases, may require complex
delivery systems that may prevent or limit their commercial use. All of the
Company's products will require regulatory approval before they may be
commercialized. Products, if any, resulting from the Company's research and
development programs are not expected to be commercially available for a number
of years, and there can be no assurance that any successfully developed
products will generate substantial revenues or that the Company will ever be
profitable.
Need for Additional Funds; History of Operating Losses
Because the Company has been unprofitable to date and expects to incur
losses for the next several years as the Company invests in product research
and development, preclinical and clinical testing and regulatory compliance,
the Company will require substantial additional funds to complete the research
and development of its product candidates, to establish commercial scale
manufacturing facilities and to market its products. The Company has
accumulated approximately $70.1 million in net losses through December 31,
1997. Estimates of the Company's future capital requirements will depend on
many factors, including: continued scientific progress in its drug discovery
programs; the magnitude of these programs; progress with preclinical testing
and clinical trials; the time and costs involved in obtaining regulatory
approvals; the costs involved in filing, prosecuting and enforcing patent
claims; competing technological and market developments; changes in its
existing research relationships; the ability of the Company to maintain and
establish additional collaborative arrangements; and effective
commercialization activities and arrangements. Subject to these factors, the
Company anticipates that its existing capital resources and its other revenue
sources, should be sufficient to fund its cash requirements through the end of
1999. Significant expenditures may be required if unanticipated clinical
trials are required to obtain regulatory approval for NOVASTAN(R) or the
Company's other product candidates. As a result, the Company may need
additional funds before any of its product candidates achieves regulatory
approval. Notwithstanding revenues which may be produced through sales of
potential future products if approved, the Company anticipates that additional
funds will need to be secured to continue the required levels of research and
development to reach its long term goals. The Company intends to seek such
additional funding through collaborative arrangements and/or through public or
private financings. There can be no assurance that additional financing will be
available, or, if available, that it will be available on acceptable terms. If
additional funds are raised by issuing securities, further dilution of the
equity ownership of existing stockholders will result. If adequate funds are
not available, the Company may be required to delay, scale back or eliminate
one or more of its drug discovery or development programs or obtain funds
through arrangements with collaborative partners or others that may require the
Company to relinquish rights to certain of its technologies, product candidates
or products that the Company would not otherwise relinquish.
Technological Change and Competition
The biopharmaceutical industry is undergoing rapid and significant
technological change and is highly competitive. The Company's success will
depend on its ability to develop and apply its technology and on its ability to
establish and maintain a market for its products. Potential competitors in the
U.S. and other countries include major pharmaceutical and chemical companies,
specialized biotechnology firms, universities and other research institutions,
many of which have substantially greater financial, technical, manufacturing
and marketing capabilities than the Company. Competitors may develop products
or other novel technologies that are more effective than any that have been or
are being developed by the Company or may obtain FDA approval for products more
rapidly than the Company. There can be no assurance that technological
development by others will not render the Company uncompetitive or that the
Company will be successful in establishing or maintaining its technological
competitiveness.
Dependence on Qualified Personnel
The Company's success is highly dependent on its ability to attract and
retain qualified scientific and management personnel. The loss of the services
of the principal members of the Company's management and scientific staff may
impede the Company's ability to commercialize its products. In order to
commercialize its products, the Company must maintain and expand its personnel,
particularly in the areas of clinical trial management, manufacturing, sales
and marketing. The Company faces intense competition for such personnel from
other companies, academic institutions, government entities and other
organizations. There can
5
7
be no assurance that the Company will be successful in hiring or retaining
qualified personnel. Managing the integration of new personnel and company
growth in general could pose significant risks to the Company's development and
progress.
The continued employment of David B. McWilliams, president and chief
executive officer and Richard A. F. Dixon, Ph.D., vice president of research is
key to the Company's success. Each of these employees has an employment
agreement with the Company. Mr. McWilliams' and Dr. Dixon's agreements are
effective through July 15, 1998 and provide for continuing one-year extensions.
The Company relies on consultants and advisors, including its
scientific advisors, to assist the Company in formulating its research and
development strategy. All of the Company's consultants and advisors are
employed by employers other than the Company and may have commitments to or
consulting or advisory contracts with other entities that may affect their
ability to contribute to the Company.
Dependence on Supplier
At present, Mitsubishi is the only manufacturer of NOVASTAN(R). In
connection with the SmithKline Agreement, Mitsubishi entered into a Supply
Agreement ("Mitsubishi Supply Agreement") with SmithKline, whereby Mitsubishi
will manufacture and supply NOVASTAN(R) in bulk in order to meet SmithKline's
and TBC's needs under the SmithKline Agreement. Should Mitsubishi fail during
any consecutive nine-month period to supply SmithKline at least 80% of its
requirements, and such requirements cannot be satisfied by existing
inventories, the Mitsubishi Supply Agreement provides for the nonexclusive
transfer of the production technology to SmithKline. However, in the event
Mitsubishi terminates manufacturing NOVASTAN(R) or defaults in its supply
commitment, there can be no assurance that SmithKline will be able to commence
manufacturing of NOVASTAN(R) in a timely manner or that alternate sources of
bulk NOVASTAN(R) will be available at reasonable cost, or at all. If SmithKline
cannot commence manufacturing of NOVASTAN(R) or alternate sources of supply are
unavailable or uneconomic, the Company's results of operations would be
materially and adversely affected.
Uncertainty Regarding Patents and Proprietary Information
The Company actively seeks patent protection for its proprietary
technology, both in the U.S. and abroad. The Company's success will depend, in
part, on its ability to obtain patents and to operate without infringing on the
proprietary rights of others. There can be no assurance that patents issued to
or licensed by the Company will not be challenged, invalidated or circumvented,
or that the rights granted thereunder will provide competitive advantages to
the Company. There can be no assurance that the Company's pending patent
applications or patent applications in preparation presently or in the future,
if and when issued, will be valid and enforceable and withstand litigation.
There can be no assurance that others will not independently develop
substantially equivalent or superseding proprietary technology or that an
equivalent product will not be marketed in competition with the Company's
products, thereby substantially reducing the value of the Company's proprietary
rights. There is a substantial backlog of pharmaceutical and biotechnology
patent applications at the U.S. Patent and Trademark Office ("PTO"). Because
patent applications in the U.S. are maintained in secrecy until patents issue,
and because publication of discoveries in the scientific or patent literature
tends to lag behind actual discoveries by several months, there can be no
assurance that the Company will obtain patent protection for its inventions. In
addition, patent protection, even if obtained, is affected by the limited
period of time for which a patent is effective. Furthermore, patent positions
of pharmaceutical and biotechnology companies, as well as those of academic and
research institutions, are highly uncertain and involve complex legal and
factual questions. This is an uncertain and developing area of the law that is
potentially subject to significant change. Therefore, the scope or
enforceability of claims allowed in the patents on which the Company will rely
cannot be predicted with any certainty.
The Company also relies on trade secrets, know-how and continuing
technological advancement to maintain its competitive position. Although the
Company has entered into confidentiality agreements with its employees and
consultants, which contain assignment of invention provisions, no assurance can
be given that others will not gain access to these trade secrets, that such
agreements will be honored or that the Company will be able to effectively
protect its rights to its unpatented trade secrets. Moreover, no assurance can
be given that others will not independently develop substantially equivalent
proprietary information and techniques or otherwise gain access to the
Company's trade secrets.
In addition to protecting its proprietary technology and trade secrets,
the Company may be required to obtain licenses to patents or other proprietary
rights from third parties. No assurance can be given that any licenses required
under any patents or proprietary rights would be made available on acceptable
terms, if at all. If the Company does not obtain required licenses, it could
encounter delays in product introductions while it attempts to design around
blocking patents, or it could find that the development, manufacture or sale of
products requiring such licenses could be foreclosed.
6
8
The Company could incur substantial costs in defending any patent
infringement suits or in asserting any patent rights, including those granted
by third parties, in a suit with another party. The PTO could institute
interference proceedings involving the Company in connection with one or more
of the Company's patents or patent applications, and such proceedings could
result in an adverse decision as to priority of invention. TBC has one
interference proceeding pending which involves compounds not currently of
commercial interest to TBC. The PTO or a comparable agency of a foreign
jurisdiction could also institute re-examination or opposition proceedings
against the Company in connection with one or more of the Company's patents or
patent applications and such proceedings could result in an adverse decision as
to the validity or scope of the patents.
Possible Volatility of Stock Price; Trading Market for Common Stock
The stock market has from time to time experienced significant price
and volume fluctuations that may be unrelated to the operating performance of
particular companies. In particular, the market price of the Company's
securities, like that of the securities of other biopharmaceutical companies,
may be highly volatile. Factors such as announcements by the Company or its
competitors concerning technological innovations, new commercial products or
procedures by the Company or its competitors, proposed governmental regulations
and developments in both the U.S. and foreign countries, disputes relating to
patents or proprietary rights, publicity regarding actual or potential medical
results relating to products under development by the Company or its
competitors, public concern as to the safety of biotechnology products, and
economic and other external factors, as well as period-to-period fluctuations
and financial results, may have a significant effect on the market price of the
Company's securities.
From time to time, there has been limited trading volume with respect
to the Common Stock. In addition, there can be no assurance that there will
continue to be a trading market or that any analysts will continue to provide
research coverage with respect to the Common Stock. Accordingly, with respect
to the Common Stock being offered hereby, no assurances can be made that such
factors will not affect the market for the Common Stock.
No Manufacturing, Marketing or Sales Activities
The Company has no manufacturing, marketing or product sales
experience. If the Company develops any commercially marketable products, there
can be no assurance that contract manufacturing services will be available in
sufficient capacity to supply the Company's product needs on a timely basis. If
the Company decides to build or acquire commercial scale manufacturing
capabilities, the Company will require additional management and technical
personnel and additional capital. No assurance can be given that the raw
materials necessary for the manufacture of the Company's products will be
available in sufficient quantities or at a reasonable cost. Complications or
delays in obtaining raw materials or in product manufacturing could delay the
submission of products for regulatory approval and the initiation of new
development programs, each of which could materially impair the Company's
competitive position and potential profitability. There can be no assurance
that the Company will be able to enter into any other supply arrangements on
acceptable terms, if at all. If at some point in the future, the Company
decides to perform its own sales and marketing activities, the Company will
require additional management, will need to hire sales and marketing personnel
and will require additional capital. No assurance can be given that qualified
personnel will be available in adequate numbers or at a reasonable cost and
there can be no assurance that the Company's sales staff will achieve success
in its marketing efforts.
Product Liability Exposure
Product liability risk is inherent in the testing, manufacture,
marketing and sale of the Company's products, and there can be no assurance
that the Company will be able to avoid significant product liability exposure.
Product liability insurance for the pharmaceutical industry, when available, is
expensive. The Company has obtained $2.0 million of product liability insurance
to cover its clinical trial programs. Pursuant to the Mitsubishi Agreement and
the SmithKline Agreement, the Company is obligated to acquire additional
coverage as the Company develops products. Existing coverage will not be
adequate as the Company further develops products and there can be no assurance
that adequate insurance coverage will be available at a reasonable cost in the
future. A future product liability claim may have a material adverse effect on
the business or financial condition of the Company.
Uncertainty of Pharmaceutical Pricing and Related Matters; Need for
Reimbursement
The future revenues and profitability of, and availability of capital
for biotechnology companies may be affected by the continuing efforts of
governmental and third-party payers to contain or reduce the costs of health
care through various means. For example, in certain foreign markets, the
pricing and profitability of prescription pharmaceuticals is subject to
government control. There have been, and there may continue to be, a number of
federal and state proposals to implement similar government control in the U.S.
It is uncertain what form any health care reform legislation may take or what
actions the federal, state and private payers may take in response to the
suggested reforms. The Company cannot predict when any reforms will be
implemented, if ever, or the effect of any implemented reform on the Company's
business. There can be no assurance that any implemented reform will not have
7
9
a material adverse effect on the Company's future results of operations. The
Company's long-term ability to market its products successfully may depend in
part on the extent to which reimbursement for the cost of such products and
related treatment will be available from public and private health insurers and
other organizations. Third-party payers are increasingly challenging the prices
of medical products and services. The reimbursement status of newly-approved
health care products is highly uncertain, and there can be no assurance that
third-party coverage will be available or that available third-party coverage
will enable the Company to maintain price levels sufficient to realize an
appropriate return on its investment in product development.
Shares Eligible for Future Sale; Registration Rights
As of March 31, 1998, substantially all of the Company's shares of
Common Stock were eligible for immediate sale in the public market. Moreover,
the resale of approximately 3.8 million shares are covered by currently
effective Form S-3 registration statements. As part of the Company's initial
public offering of securities in 1993 (the "Initial Public Offering"), warrants
covering approximately 4.1 million shares (with an exercise price of $8.44 per
share) were issued and remain outstanding and the shares issuable upon exercise
are registered for sale. In addition, as part of the Initial Public Offering,
the underwriters were issued 355,000 options to purchase units (each unit
consisting of one share of Common Stock and one warrant to purchase Common
Stock) at an exercise price of $11.14 per share (the warrants are also
exercisable at $11.14 per share). The sale of the Common Stock underlying the
units are also registered. The resale of 36,399 shares issuable on exercise of
the 1991 Warrants and 113,636 shares issuable on exercise of the 1996 Warrants
are registered hereby. Furthermore, the resale of an aggregate of
approximately 130,000 shares issuable upon exercise of other warrants (with
exercise prices from $3.50 to $4.58 per share) are registered on currently
effective Form S-3 registration statements. Other warrants exercisable for
approximately 500,000 shares (with an exercise price of $3.66) are not
currently registered for resale, but have piggyback registration rights.
SmithKline also has piggyback registration rights on 176,992 shares issued
pursuant to the SmithKline Agreement. Approximately 2.9 million shares of
Common Stock are issuable upon exercise of outstanding employee stock options
and will become eligible for sale in the public markets at prescribed times in
the future. The Company's issuances of such 3.4 million shares are registered
on Form S-8 registration statements. As of March 31, 1998, such options were
exercisable to purchase approximately 2.1 million shares of Common Stock. TBC
has issued to Genentech, Inc. ("Genentech"), a former licensor of NOVASTAN(R),
an additional 214,286 shares of Common Stock, and has agreed to issue an
additional 71,429 shares of Common Stock within ten days after the FDA's first
approval of an NDA for NOVASTAN(R). The Company has also granted Genentech a
warrant to purchase an additional 142,858 shares of Common Stock at an exercise
price of $14.00 per share, subject to adjustment. The Company has granted
Genentech registration rights for all 714,287 shares issued or issuable to
Genentech. In total, as of March 31, 1998 the Company has reserved
approximately 8.7 million shares of Common Stock for issuance pursuant to
outstanding options, warrants, other contingent agreements. Approximately 8.1
million of these shares of reserved Common Stock are registered for sale or
resale on currently effective registration statements, and substantially all of
the remaining shares of reserved Common Stock are entitled to registration
rights under the Securities Act. The issuance of a significant number of shares
of Common Stock upon the exercise of stock options and warrants, or the sales
of a substantial number of shares of Common Stock pursuant to Rule 144 or
otherwise, could adversely affect the market price of the Common Stock.
Anti-Takeover Provisions
The Company's Certificate of Incorporation and the Delaware General
Corporation Law (the "DGCL") contain certain provisions that may delay or
prevent an attempt by a third-party to acquire control of the Company. In
addition, the severance provisions of employment agreements with certain
members of management could impede an attempted change of control of the
Company.
Legal Proceedings
The Company and certain of its officers and directors are parties to
certain litigation arising out of the Company's IPO. Given the early stage of
this case, the Company is unable to evaluate its potential outcome at this
time. The Company disputes these claims and intends to contest them vigorously.
There can be no assurance, however, that the final disposition of this case
will be favorable to the Company.
Disclosure Regarding Forward Looking Statements
All statements other than statements of historical fact included in and
incorporated by reference into this Prospectus are "forward looking
statements." Such forward looking statements include, without limitation,
statements under "Risk Factors, - Need for Additional Funds; History of
Operating Losses" regarding TBC's estimate of sufficiency of existing capital
resources and ability to raise additional capital to fund cash requirements for
future operations, and "Risk Factors - No Assurance of Regulatory Approval;
Need for Extensive Clinical Trials" regarding the uncertainties involved in the
drug development process and the timing of regulatory approvals required to
market these drugs. Although TBC believes that the expectations reflected in
such forward looking statements
8
10
are reasonable, it can give no assurance that such expectations reflected in
such forward looking statements will prove to have been correct. The ability to
achieve TBC's expectations is contingent upon a number of factors which
include, without limitation, (i) ongoing cost of research and development
activities, (ii) cost of clinical development of product candidates, (iii)
attainment of research and clinical goals of product candidates, (iv) timely
approval of TBC's product candidates by appropriate governmental and regulatory
agencies, (v) effect of any current or future competitive products, (vi)
ability to manufacture and market products commercially, (vii) retention of key
personnel and (viii) capital market conditions.

PLAN OF DISTRIBUTION
Pursuant to this Prospectus, the Selling Stockholders, or by certain
pledgees, donees, transferees or other successors in interest, may sell Shares
from time to time in transactions on AMEX, in privately-negotiated transactions
or by a combination of such methods of sale, at fixed prices which may be
changed, at market prices prevailing at the time of sale, at prices related to
such prevailing market prices or at negotiated prices. The Selling
Stockholders may effect such transactions by selling the Shares to or through
broker-dealers, and such broker-dealers may receive compensation in the form of
discounts, concessions or commissions from the Selling Stockholders or the
purchasers of the Shares for whom such broker-dealers may act as agent or to
whom they sell as principal, or both (which compensation to a particular
broker-dealer might be in excess of customary commissions).
Other methods by which the Shares may be sold include, without
limitation: (i) transactions which involve cross or block trades or any other
transaction permitted by the AMEX, (ii) "at the market" to or through market
makers or into an existing market for the Common Stock, (iii) in other ways not
involving market makers or established trading markets, including direct sales
to purchasers or sales effected through agents, (iv) through transactions in
options or swaps or other derivatives (whether exchange-listed or otherwise),
or (v) any combination of any such methods of sale. The Selling Stockholders
may also enter into option or other transactions with broker-dealers which
require the delivery to such broker dealers of the Common Stock offered hereby,
which Common Stock such broker-dealers may resell pursuant to this Prospectus.
The Selling Stockholders and any broker-dealers who act in connection with
the sale of Shares hereunder may be deemed to be "underwriters" as that term is
defined in the Securities Act, and any commissions received by them and profit
on any resale of the Shares as principal might be deemed to be underwriting
discounts and commissions under the Securities Act.
Pursuant to a Registration Rights Agreement with certain Selling
Stockholders, the Company has agreed to indemnify certain of the Selling
Stockholders and each underwriter against certain liabilities, including
certain liabilities under the Securities Act as amended, or will contribute to
payments such Selling Stockholders or underwriters may be required to make in
respect of certain losses, claims, damages or liabilities.

PART II
INFORMATION NOT REQUIRED IN PROSPECTUS
Item 14. Other Expenses of Issuance and Distribution.
The estimated expenses payable by the Company in connection with the
offering of the shares of Common Stock to be registered and offered hereby are
as follows (the Commission registration fees and AMEX listing fees of $22,619
in the aggregate were previously paid):
Legal fees and expenses . . . . . . . . . . . . . . . . . 5,000
Accounting fees and expenses . . . . . . . . . . . . . . 4,000

-------
Total . . . . . . . . . . . . . . . . . . . . . $12,000
=======
All such expenses are estimates except for the Commission registration
fee and AMEX listing fee, which were previously paid.
Item 15. Indemnification of Directors and Officers.
Section 145 of the Delaware General Corporation Law permits a
corporation to indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, by reason
of the fact that he is or was a director, officer, employee or agent of the
corporation or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action.
In an action brought to obtain a judgment in the corporation's favor,
whether by the corporation itself or derivatively by a stockholder, the
corporation may only indemnify for expenses, including attorney's fees,
actually and reasonably incurred in connection with the defense or settlement
of such action, and the corporation may not indemnify for amounts paid in
satisfaction of a judgment or in settlement of the claim. In any such action,
no indemnification may be paid in respect of any claim, issue or matter as to
which such person shall have been adjudged liable to the corporation except as
otherwise approved by the Delaware Court of Chancery or the court in which the
claim was brought. In any other type of proceeding, the indemnification may
extend to judgments, fines and amounts paid in settlement, actually and
reasonably incurred in connection with such other proceeding, as well as to
expenses (including attorneys' fees).
The statute does not permit indemnification unless the person seeking
indemnification has acted in good faith and in a manner be reasonably believed
to be in, or not opposed to, the best interests of the corporation and, in the
case of criminal actions or proceedings, the person had no reasonable cause to
believe his conduct was unlawful. There are additional limitations applicable
to criminal actions and to actions brought by or in the name of the
corporation. The determination as to whether a person seeking indemnification
has met the required standard of conduct is to be made (i) by a majority vote
of a quorum of disinterested members of the board of directors, (ii) by
independent legal counsel in a written opinion, if such a quorum does not exist
or if the disinterested directors so direct, or (iii) by the stockholders.
As permitted by the Delaware General Corporation Law ("DGCL"), the
Company's Bylaws provide that it will indemnify the directors, officers,
employees and agents of the Company against certain liabilities that they may
incur in their capacities as directors, officers, employees and agents.
Furthermore, the Company's Certificate of Incorporation, as amended,
indemnifies the directors, officers, employees, and agents of the Company to
the maximum extent permitted by the DGCL. The Company has also entered into
agreements with its officers and directors providing for indemnity to the
maximum extent permitted under the DGCL. The Company has director and officer
liability insurance policies that provide coverage of up to $10.0 million
except that no current coverage is provided for any liabilities arising from
the existing lawsuits. The existing lawsuits are covered under prior policies.
