                         TEXAS BIOTECHNOLOGY CORPORATION
                         7000 FANNIN STREET, 20TH FLOOR
                              HOUSTON, TEXAS 77030

                                 PROXY STATEMENT

         Our Board of Directors is soliciting proxies for the annual meeting of
our stockholders to be held in Houston, Texas on May 30, 2001, and at any
adjournment thereof, for the purposes set forth in the accompanying notice. This
proxy statement and the accompanying proxy card are first being mailed to
stockholders on or about April 24, 2001. Because many stockholders are unable to
attend the meeting, the board of directors solicits proxies to ensure that each
stockholder has an opportunity to vote on all matters scheduled to come before
the meeting. Stockholders are urged to read carefully the material in this proxy
statement.

                              QUESTIONS AND ANSWERS

Q:       Who can attend and vote at the meeting?

A:       You can attend and vote at the meeting if you were a stockholder at the
         close of business on the record date, April 16, 2001. On that date,
         there were 43,771,186 shares of common stock outstanding and entitled
         to vote at the meeting.

Q:       What am I voting on?

A:       You are voting on:

         -        The election of directors; and

         -        The approval of an amendment to the 1999 Stock Incentive Plan.

Q:       How do I cast my vote?

A:       If you hold your shares as a stockholder of record, you can vote in
         person at the annual meeting or you can vote by mail. The enclosed
         proxy card contains instructions for voting by mail. If you are a
         street-name stockholder, you will receive instructions from your bank,
         broker or other nominee describing how to vote your shares. If you do
         not instruct your broker or nominee how to vote such shares, they may
         vote your shares as they decide as to matters for which they have
         discretionary authority under American Stock Exchange rules.

         The proxies identified on the back of the proxy card, Messrs.
         McWilliams and Mueller and Dr. Dixon, will vote the shares of which you
         are the stockholder of record in


                                       1


   4


         accordance with your instructions. If you submit a proxy card without
         giving specific voting instructions, the proxies will vote those shares
         as recommended by the board of directors.

Q:       How does the board recommend I vote on the proposals?

A:       The board recommends you vote "FOR" each of the nominees to the board
         of directors and "FOR" the amendment to the 1999 Stock Incentive Plan.

Q:       Can I revoke my proxy?

A:       Yes. You can revoke your proxy at any time before it is exercised by:

         -        submitting a properly signed proxy card with a more recent
                  date;

         -        giving written notice of your revocation before the meeting to
                  our Secretary, Mr. Mueller, at our offices, 7000 Fannin
                  Street, 20th Floor, Houston, Texas 77030; or

         -        attending the meeting and voting your shares in person.

Q:       Who will count the vote?

A:       A representative of our transfer agent, Bank of New York, will act as
         the inspector of the election and will count the vote.

Q:       What is a "quorum?"

A:       A quorum is the presence at the meeting, in person or by proxy, of the
         holders of a majority of the outstanding shares as of the record date.
         There must be a quorum for the meeting to be held. If you submit a
         valid proxy card or attend the meeting, your shares will be counted to
         determine whether there is a quorum. Abstentions and broker non-votes
         will be counted toward the quorum. "Broker non-votes" occur when
         nominees (such as banks and brokers) that hold shares on behalf of
         beneficial owners do not receive voting instructions from the
         beneficial owners before the meeting and do not have discretionary
         voting authority to vote those shares.

Q:       What vote is required to approve each item?

A:       The nominees for election as directors at the annual meeting who
         receive the greatest number of votes cast by the stockholders, a
         plurality, will be elected as directors. In the election of directors,
         you may vote "FOR" all nominees, "AGAINST" all nominees or withhold
         your vote for any one or more of the nominees. The approval of the
         amendment to the 1999 Stock Incentive Plan, commonly referred to as the
         1999 Plan, and all other matters to be considered at the meeting
         require the affirmative vote of a majority of the shares entitled to
         vote and present in person or by proxy at the meeting. For the approval
         of the amendment to the 1999 Plan, you may vote "FOR" or "AGAINST" or
         abstain from voting. In a plurality vote, abstentions are not
         considered a vote cast and will not affect the outcome. In a majority
         vote, however, express abstentions have the effect of a vote against a
         particular proposal. Broker non-votes will not affect the outcome of
         any vote on the proposals presented at the annual meeting because the
         broker or nominee lacks the authority to vote on these matters.

Q:       What shares are included on my proxy card?

A:       Your proxy card represents all shares registered to your account in the
         same social security number and address.

Q:       What does it mean if I get more than one proxy card?

A:       Your shares are probably registered in more than one account. You
         should vote each proxy card you receive. We encourage you to
         consolidate all your accounts by registering them in the same name,
         social security number and address.

Q:       How many votes can I cast?

A:       On all matters you are entitled to one vote per share of common stock.

Q:       When are stockholder proposals due for the 2002 Annual Meeting of
         Stockholders?

A:       If you want to present a proposal from the floor at the 2002 Annual
         Meeting, you must give us written notice of your proposal no later than
         March 10, 2002. If instead of presenting your proposal at the meeting
         you want your proposal to be considered for inclusion in next year's
         proxy statement, you must submit the proposal in writing to the
         Secretary so that it is received at the above address by December 25,
         2001. Your notice


                                       3

   6

         should be sent to the Secretary, Texas Biotechnology Corporation,
         7000 Fannin, 20th Floor, Houston, Texas 77030.

Q:       Where can I find the voting results of the meeting?

A:       The preliminary voting results will be announced at the meeting. The
         final results will be published in our quarterly report on Form 10-Q
         for the second quarter of fiscal 2001.

                              ELECTION OF DIRECTORS

         At the annual meeting, nine directors are to be elected. Each director
is to hold office until the next annual meeting of stockholders or until his
successor is elected and qualified. The persons designated as proxies on the
accompanying proxy card intend, unless authority is withheld, to vote for the
election of the nominees named below to the board of directors. All of the
nominees have previously been elected by our stockholders. If any nominee should
become unavailable for election, the proxy may be voted for a substitute nominee
selected by the persons named in the proxy or the board of directors may be
reduced accordingly; however, we are not aware of any circumstances likely to
render any nominee unavailable.

VOTE REQUIRED FOR ELECTION

         The nine nominees for election as directors at the annual meeting who
receive the greatest number of votes cast for election by the stockholders will
be elected as our directors.

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR EACH NOMINEE TO OUR BOARD
OF DIRECTORS.

DIRECTOR COMPENSATION AND BOARD COMMITTEES

         During 2000, the board of directors held nine meetings. All directors,
except for Dr. Ron Anderson, attended at least 75% of the total meetings of the
board and the committees on which they serve. We believe that attendance at
meetings of the board is only one criterion for judging the contribution of
individual directors, and that all directors have made substantial and valuable
contributions.

         Director Compensation. During the year ended December 31, 2000, each
non-employee director received a retainer of $2,000 per quarter, fees of $1,000
for each meeting of the board of directors attended in person and $150 for each
meeting conducted by telephone. Non-employee directors received a fee of $200
for each committee meeting attended in person and a fee of $100 for each
committee meeting conducted by telephone. Dr. Willerson, however, has declined
all retainer or meeting fees. In addition, directors are reimbursed for expenses
incurred in attending meetings of the board and its committees. Non-employee
directors may elect to receive part or all of the quarterly retainer and fees in
common stock. Each non-employee director also receives options to purchase
15,000 shares of common stock on their initial election to the board and options
to purchase 7,500 shares of common stock on each subsequent election to the
board.

Under the rules of the American Stock Exchange, all of the members of the Audit
Committee are independent. The Audit Committee operates under a written charter
adopted by the Board of Directors on June 6, 2000. The audit committee met twice
during 2000. The audit committee assists the board in fulfilling its oversight
responsibilities to stockholders and other matters relating to our corporate
accounting and reporting practices and the quality and integrity of our
financial reports. The audit committee recommends the selection of independent
accountants, reviews the independent accountants' report on our internal control
systems and reviews the scope and results of the external audit process.

         Compensation and Personnel Committee. The current members of the
compensation and personnel committee are John M. Pietruski (Chair), Frank C.
Carlucci and James A. Thomson. The compensation and personnel committee met five
times during 2000. The compensation and personnel committee reviews and
recommends to the board of directors the compensation and employee benefits for
our elected officers, and the key officers and employees who participate in
various incentive compensation plans. This committee approves the grant of
employee stock awards in accordance with our various incentive stock plans and
administers any incentive plans and bonus plans. The compensation and personnel
committee is also responsible for reviewing our significant personnel
compensation policies and benefit programs and major changes thereto, and our
management's long-range planning for executive development and succession. This
committee establishes policies on management perquisites, and also monitors our
non-discrimination polices and practices. Following the compensation and
personnel committee's review and approval, all issues pertaining to officer
compensation, other than employee stock awards, are submitted to the full board
of directors for approval.

                                   PROPOSAL 2

           APPROVAL OF THE AMENDMENT TO THE 1999 STOCK INCENTIVE PLAN

The 1999 Plan provides for the grant of:

         -        incentive and non-qualified stock options;

         -        incentive stock options;

         -        shares of restricted stock; and

         -        stock bonuses.

         Currently, the 1999 Plan provides that the maximum amount of shares
subject to the plan is 1,000,000. As of March 31, 2001, no shares remained
available for grant under the 1999 Plan. Because of this, the board adopted this
amendment, subject to stockholder approval, to assure that adequate shares will
be available for grant pursuant to the 1999 Plan. The amendment to the 1999 Plan
is intended to (i) further our efforts in attracting, retaining and motivating
key employees, consultants, and non-employee directors and (ii) continue to
closely align the interests of participants in the 1999 Plan with those of
stockholders by encouraging stock ownership and by tying compensation to the
long term growth of our business and the performance of the Common Stock. If
this amendment is approved, the authorized shares available for use pursuant to
the 1999 Plan will be increased from 1,000,000 to 3,000,000. If approved, this
amendment will not change any other material term of the 1999 Plan.

           The 1999 Stock Incentive Plan Amendment appears as Exhibit A to this
proxy statement.

VOTE REQUIRED FOR APPROVAL

         The affirmative vote of the holders of a majority of the shares of
common stock outstanding, entitled to vote and represented at the annual
meeting, in person or by proxy, is required to approve the 1999 Plan amendment.

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE AMENDMENT
TO THE 1999 PLAN.

(1)      Potential Realizable Value is based on the assumed annual growth rates
         for each of the grants shown over their ten-year option term. Actual
         gains, if any, on option exercises are dependent on the future
         performance of the common stock. Because the exercise price of options
         granted is equal to the fair market value of the common stock a zero
         percent appreciation in stock price will result in no gain.

(2)      These are incentive stock options, to the extent allowed by law, and
         vest and become exercisable in approximately equal annual installments
         over a three-year period beginning March 6, 2001.

         Compensation Committee Interlocks and Insider Participation. In January
1992, we entered into a consulting agreement with John M. Pietruski, Chairman of
our board of directors. Under the terms of the agreement, Mr. Pietruski is
expected to devote an average of one day per week of his consulting services to
us, for which he receives an annual fee of $75,000. On January 1, 2001, the
agreement was extended for a two-year period at the same annual fee.

COMPENSATION AND PERSONNEL COMMITTEE REPORT ON EXECUTIVE COMPENSATION

         Our compensation program for officers (including the Chief Executive
Officer and the other Named Executive Officers) is administered by the
Compensation and Personnel Committee, which is composed of three non-employee
directors. The committee makes decisions regarding the reward of stock options
and stock incentives under the company's stock option plans. Following review
and approval by the Committee, all other issues pertaining to officer
compensation (other than stock options and stock incentives) are submitted to
the full board of directors for approval. The objective of our compensation
program is to provide a total compensation package that will enable us to
attract, motivate and retain outstanding individuals and align their success
with that of the stockholders.

         Base salaries for management employees are determined initially by
evaluating the responsibilities of the position held and the experience of the
individual, and by reference to the competitive marketplace for management
talent, including a comparison of base salaries for comparable positions at
comparable companies within the biotechnology industry. We entered into an
employment contract with David McWilliams, the company's President and Chief
Executive Officer, because we felt that the terms of this agreement were
necessary in order to retain a candidate of Mr. McWilliams' experience and
reputation in the biopharmaceutical industry, which in turn was deemed necessary
in order to enable us to move towards our long-range goal of developing and
marketing commercially viable biopharmaceutical products. In furtherance of
these goals, we have also entered into employment contracts with our other key
management personnel. See "Employment Agreements." The employment agreements
with key personnel establish annual base salary amounts that the board of
directors, on recommendation of the committee, may increase from time to time.
Annual salary adjustments are determined by evaluating the competitive
marketplace, our performance, the performance of the executive, and any
increased responsibilities assumed by the executive. We attained a number of
important milestones during the year 2000 including the approval and launch of
Argatroban, execution of development agreements with ICOS Corporation and
Schering-Plough, a successful equity offering, creation and funding of Revotar,
a German subsidiary, and progress in research and clinical development of
certain compounds. Based on the attainment of these significant milestones, the
committee recommended and the board of directors approved an increase in Mr.
McWilliams' compensation by 6.5% effective September 1, 2000 and 8.33% effective
March 1, 2001.

         The Revenue Reconciliation Act of 1993 restricts the ability of a
publicly held corporation to deduct compensation in excess of $1,000,000 paid to
its chief executive officer and the four most highly compensated officers. The
committee intends to maintain executive compensation packages below this
threshold, and based on its current compensation structure, the company does not
anticipate that any of its officers will reach the $1,000,000 threshold in the
near future.

         The principal methods for long-term incentive compensation are the
company's incentive stock plans. Compensation under these plans principally
takes the form of incentive and non-qualified stock options with an exercise
price of market price at time of grant and restricted stock


                                       16
   19

grants. In this manner, key individuals are rewarded commensurate with increases
in stockholder value. Moreover, the company's incentive stock plans provide a
non-cash form of compensation, which is intended to benefit the company by
enabling it to continue to attract and to retain qualified personnel. In
addition, during 1998, the board of directors instituted a bonus plan for
executive officers and certain other key personnel. Bonuses are paid based upon
attainment of annual corporate goals as approved by the board of directors.
Payments are a combination of cash and restricted common stock. The restricted
stock vests in three equal amounts over three years beginning one year from date
of grant. No bonuses were paid for years prior to 2000. During 2000, Mr.
McWilliams earned $281,246 pursuant to the bonus plan of which a cash component
in the amount of $140,625 and restricted stock valued at $140,621 was paid
during 2001 following the attainment of the goals established by the committee.

         The committee is authorized to make incentive awards under the stock
plans mentioned above to key employees, including officers of the company. In
determining incentive awards for management, the committee considers
management's ability to implement our research and clinical development
programs, successful completion of corporate partnering agreements, financing
activities, and control of expenses. The committee utilizes incentive awards as
a key element to provide incentives for employees and officers consistent with
the goal of increasing stockholder value.

         Based on these criteria, during the fiscal year ended December 31,
2000, we granted Mr. McWilliams options to purchase 22,500 shares of common
stock at an exercise price of $20.125 per share and 34,323 shares at $16.9375
per share. At December 31, 2000, Mr. McWilliams held options covering an
aggregate of 720,775 shares of common stock. Of those, options covering an
aggregate of 608,745 shares were vested and exercisable.

AUDIT COMMITTEE REPORT

         The Audit Committee of the board of directors is responsible for
monitoring the integrity of the company's consolidated financial statements, its
system of internal controls and the independence and performance of its
independent accountants. The Audit Committee also recommends to the board of
directors the retention and selection of the company's independent accountants.
A copy of the Audit Committee Charter is attached to this Proxy Statement as
Appendix B.

         The Audit Committee is also responsible for oversight of the financial
reporting process, including the system of internal control, and the preparation
of consolidated financial statements in accordance with generally accepted
accounting principles. The company's independent accountants are responsible for
auditing those financial statements. Our responsibility is to monitor and review
these processes. However, we are not professionally engaged in the practice of
accounting or auditing and are not experts in the fields of accounting or
auditing. We rely, without independent verification, on the information provided
to us and on the representations made by management and the independent
accountants.

         We have met with the company's independent accountants, KPMG LLP, and
discussed the overall scope and plans for their audit. We have also met with the
independent accountants, with and without management present, to discuss the
results of their examinations and their evaluations of the company's internal
controls. We also discussed with the independent accountants matters required to
be discussed with audit committees under generally accepted auditing standards,
including, among other things, matters related to the conduct of the audit of
the company's consolidated financial statement and the matters required to be
discussed by Statement on Auditing Standards No. 61 as amended.

         The independent accountants also provided to us the written disclosures
and the letter required by Independence Standards Board Standard No. 1, and we
discussed with the independent accountants their independence from the company.
When considering KPMG's independence, we considered the non-audit services
provided by the independent accountants and concluded that such services are
compatible with maintaining their independence.

         We have reviewed and discussed the audited consolidated financial
statements for the fiscal year ended December 31, 2000 with management and KPMG.
Based on our review of the audited consolidated financial statements and the
meetings and discussions with management and the independent accountants, and
subject to the limitations on our role and responsibilities referred to above
and in the Audit Committee Charter, we recommended to the board of directors
that the company's audited consolidated financial statements be included in the
company's Annual Report on Form 10-K filed with the Securities and Exchange
Commission.

EXECUTIVE EMPLOYMENT AND SEVERANCE AGREEMENTS

         In July 1992, we entered into a three-year employment agreement with
David B. McWilliams to serve as our President and Chief Executive Officer. Upon
the expiration of the initial term, the agreement automatically renews for
successive one-year periods unless either party provides notice at least sixty
days before scheduled expiration. Effective March 1, 2001, the compensation
committee increased Mr. McWilliams' annual salary package to $325,000. We may
terminate Mr. McWilliams' employment for any reason; however, if such
termination is not due to disability or for cause, Mr. McWilliams will be
entitled to receive his salary and benefits under the agreement for one year
following termination.

         In July 1990, we entered into a five-year employment agreement with Dr.
Richard A.F. Dixon to serve as our Scientific Director and Director of Molecular
Biology. Upon the expiration of the initial term, the agreement automatically
renews for successive one-year periods unless either party provides written
notice at least thirty days before scheduled expiration. If we terminate this
agreement with Dr. Dixon for cause, he will be entitled to one month salary,
otherwise, salary is due for the remaining contract term. Effective March 1,
2001, the compensation committee increased Dr. Dixon's annual salary to
$270,000.

         We entered into an employment agreement with Pamela M. Murphy in March
1998. Effective March 1, 2001, the compensation committee increased Ms. Murphy's
annual salary to $157,000. This agreement may be terminated at any time, with or
without cause, by either Ms. Murphy or us. However, if we terminate this
agreement with Ms. Murphy other than for cause, she will be entitled to receive
six months salary.

         We entered into an employment agreement with Joseph M. Welch in June
1993. Effective March 1, 2000, the compensation committee increased Mr. Welch's
annual salary to $171,150. This agreement may be terminated at any time, with or
without cause, by either Mr. Welch or us. However, if we terminate this
agreement with Mr. Welch other than for cause, he will be entitled to receive
six months salary.

         In addition, we signed agreements with the Named Executive Officers to
provide certain benefits in the event of a change of control. The agreements
provide for a lump-sum payment in cash ranging from 18 months to three years of
annual base salary and annual bonus if any. Presently, the base salary portion
payable under these agreements would aggregate approximately $3.1 million. In
addition, the agreements provide for gross-up for certain taxes on the lump-sum
payment, continuation of certain insurance and other benefits for periods of 18
months to three years and reimbursement of certain legal expenses in conjunction
with the agreements. These provisions are intended to replace compensation
continuation provisions of any other agreement in effect for an officer if the
specified event occurs.

AUDITORS

         KPMG LLP has served as our independent auditors for a number of years.
Although we anticipate that this relationship will continue to be maintained
during fiscal 2001, we have not proposed any formal action be taken at the
meeting concerning the continued employment of KPMG LLP, because no such action
is legally required. Representatives of KPMG LLP plan to


                                       20
   23

attend the annual meeting and will be available to answer appropriate questions.
These representatives will be able to make a statement at the meeting if they
wish, although we do not expect them to do so.

         During the calendar year 2000, we incurred professional service fees
with KPMG LLP as indicated below:

         AUDIT FEES

                  The aggregate fees billed or expected to be billed by KPMG
         related to the 2000 annual financial statement audit and reviews of
         quarterly financial statements included in our Quarterly Reports filed
         on Form 10-Q were $77,000.

         FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES

                  KPMG provided no information technology services relating to
         financial information systems design and implementation during the
         fiscal year ended December 31, 2000.

         ALL OTHER FEES

                  The aggregate fees billed or expected to be billed by KPMG for
         services rendered to us, other than the services described above under
         "Audit Fees", for the fiscal year ended December 31, 2000 are
         approximately $137,000. Of this amount, $100,000 represented fees
         associated with work performed in conjunction with the public offering
         of common stock during the year 2000 and the remainder is primarily for
         tax services.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Securities Exchange Act of 1934, as amended,
requires our directors and executive officers, and persons who own more than 10%
of our equity securities to file initial reports of ownership and reports of
changes in ownership of our common stock with the Securities and Exchange
Commission and to furnish us a copy of each filed report.

         Except for Mr. McWilliams, who filed a Form 4 regarding one late
transaction, to our knowledge, based solely on review of the copies of such
reports furnished to us and written representations that no other reports were
required, during the fiscal year ended December 31, 2000, our officers,
directors and greater than 10% beneficial owners timely filed all required
Section 16(a) reports.

                       1999 STOCK INCENTIVE PLAN AMENDMENT

         The 1999 Stock Incentive Plan (the "1999 Plan") of Texas Biotechnology
Corporation (the "Company") is hereby amended as follows effective March 13,
2001.

         1.       Section 1.4 is amended to read as follows in its entirety:

                  Subject to adjustment under Section 5.5, there shall be
         available for Incentive Awards under the Plan granted wholly or partly
         in Common Stock (including rights or Stock Options that may be
         exercised for or settled in Common Stock) Three Million (3,000,000)
         Shares of Common Stock. Three Million (3,000,000) of the Shares
         reserved under the Plan shall be available for grants of Incentive
         Stock Options. The number of Shares of Common Stock that are the
         subject of Incentive Awards under this Plan, that are forfeited or
         terminated, expire unexercised, are settled in cash in lieu of Common
         Stock or in a manner such that all or some of the Shares covered by an
         Incentive Award are not issued to a Grantee or are exchanged for
         Incentive Awards that do not involve Common Stock, shall again
         immediately become available for Incentive Awards hereunder. The
         Committee may from time to time adopt and observe such procedures
         concerning the counting of Shares against the Plan maximum as it may
         deem appropriate. The Board and the appropriate officers of the Company
         shall from time to time take whatever actions are necessary to file any
         required documents with governmental authorities, stock exchanges and
         transaction reporting systems to ensure that Shares are available for
         issuance pursuant to Incentive Awards.

                  During such period that the Company is a Publicly Held
         Corporation, then unless and until the Committee determines that a
         particular Incentive Award granted to a Covered Employee is not
         intended to comply with the Performance-Based Exception, the following
         rules shall apply to grants of Incentive Awards to Covered Employees:

                           (a)      Subject to adjustment as provided in Section
                  5.5, the maximum aggregate number of Shares of Common Stock
                  (including Stock Options, Restricted Stock, or Other
                  Stock-Based Awards paid out in Shares) that may be granted or
                  that may vest, as applicable, in any calendar year pursuant to
                  any Incentive Award held by any individual Covered Employee
                  shall be 3,000,000 Shares.

                           (b)      The maximum aggregate cash payout (including
                  Other Stock-Based Awards paid out in cash) with respect to
                  Incentive Awards granted in any calendar year which may be
                  made to any Covered Employee shall be Ten Million dollars
                  ($10,000,000).

                           (c)      With respect to any Stock Option granted to
                  a Covered Employee that is canceled or repriced, the number of
                  Shares subject to such Stock Option


                                      A-1
   26

                  shall continue to count against the maximum number of Shares
                  that may be the subject of Stock Options granted to such
                  Covered Employee hereunder and, in this regard, such maximum
                  number shall be determined in accordance with Section 162(m)
                  of the Code.

                           (d)      The limitations of subsections (a), (b) and
                  (c) above shall be construed and administered so as to comply
                  with the Performance-Based Exception.

                                     CHARTER
                                     OF THE
                                 AUDIT COMMITTEE
                                     OF THE
                               BOARD OF DIRECTORS

                       (As initially adopted June 6, 2000)

I.       PURPOSE

         The Audit Committee is a standing committee of the Board of Directors
         (the "Board") of Texas Biotechnology Corporation, a Delaware
         corporation (the "Company"). Its primary function is to assist the
         Board in fulfilling its oversight responsibilities by:

         -        Reviewing the financial reports and other financial
                  information provided by the Company to any governmental body
                  or the public;

         -        Reviewing the Company's system of internal controls regarding
                  finance, accounting, legal compliance and ethics that
                  management and the Board have established; and the Company's
                  auditing, accounting and financial reporting processes
                  generally;

         -        Reviewing the independence and performance of the Company's
                  independent auditors; and

         -        Providing an open avenue of communication among the
                  independent auditors, financial and senior management, and the
                  Board.

         The Audit Committee will primarily fulfill these responsibilities by
         carrying out the activities enumerated in Section IV of this Charter.
         The Audit Committee has direct access to the Company's independent
         auditors and anyone in the Company. The Audit Committee has authority
         to retain, at the Company's expense, special legal, accounting, or
         other consultants or experts it deems necessary in the performance of
         its duties.

II.      COMPOSITION

         The Audit Committee shall be comprised of at least three directors,
         each of whom shall be independent directors, and free from any
         relationship that, in the opinion of the Board, would interfere with
         the exercise of his or her independent judgment as a member of the


                                      B-1
   28

         Audit Committee. Directors with any of the following relationships will
         not be considered independent:

         -        a director being employed by the Company or any of its
                  affiliates for the current year or any of the past three
                  years;

         -        a director accepting any compensation from the Company or any
                  of its affiliates in excess of $60,000 during the previous
                  fiscal year, other than compensation for Board service,
                  benefits under a tax-qualified retirement plan or
                  non-discretionary compensation;

         -        a director being a member of the immediate family of an
                  individual who is, or has been in any of the past three years,
                  employed by the Company or any of its affiliates as an
                  executive officer (immediate family includes a person's
                  spouse, parents, children, siblings, mother-in-law,
                  father-in-law, brother-in-law, sister-in-law, son-in-law,
                  daughter-in-law, and anyone who resides in such person's
                  home);

         -        a director being a partner in, or a controlling stockholder or
                  an executive officer of, any for-profit business organization
                  to which the Company made, or from which the Company received,
                  payments (other than those arising solely from investments in
                  the Company's securities) that exceed 5% of the Company's or
                  the business organization's consolidated gross revenues for
                  that year, or $200,000, whichever is more, in any of the past
                  three years; or

         -        a director being employed as an executive of another entity
                  where any of the Company's executives serves on that entity's
                  compensation committee.

         One director who is not independent and is not a current employee or an
         immediate family member of such employee may be appointed to the Audit
         Committee if the Board, under exceptional and limited circumstances,
         determines that membership on the Audit Committee by the individual is
         required by the best interest of the Company and its stockholders, and
         the Company discloses, in the next annual proxy statement subsequent to
         such determination, the nature of the relationship and the reasons for
         that determination.

         All members of the Audit Committee shall be able to read and understand
         fundamental financial statements, including the Company's balance
         sheet, income statement, and cash flow statement, or will be able to do
         so within a reasonable period of time after appointment to the Audit
         Committee. Audit Committee members may enhance their familiarity with
         finance and accounting by participating in educational programs
         conducted by the Company or an outside consultant. At least one member
         of the Audit Committee shall have past employment experience in finance
         or accounting, requisite professional certification in accounting, or
         any other comparable experience or background which results in the
         individual's financial sophistication, including being or having been a
         chief executive officer, chief financial officer or other senior
         officer with financial oversight responsibilities.


                                      B-2
   29

         The members of the Audit Committee shall be appointed by the Board at
         the annual meeting of the Board, and shall serve on the Audit Committee
         for a term coinciding with their Board term. If a Chair of the Audit
         Committee is not appointed by the Board, the Audit Committee shall
         itself designate a Chair.

III.     MEETINGS

         The Audit Committee shall meet at least two times annually, or more
         frequently as circumstances dictate. The purpose of the two scheduled
         meetings of the Audit Committee is to review and approve the annual
         financial results of the Company prior to release and to review and
         approve the scope of the annual audit to be performed by the Company's
         independent auditors. As part of its job to foster open communication,
         the Audit Committee should meet at least annually with management and
         the independent auditors in separate executive sessions to discuss any
         matters that the Audit Committee and each of these groups believe
         should be discussed privately. In addition, the Audit Committee or at
         least its Chair should meet with the independent auditors and
         management quarterly to review the Company's financial statements
         consistent with IV. 4 below.

IV.      RESPONSIBILITIES AND DUTIES

         To fulfill its responsibilities and duties the Audit Committee shall:

         Documents/Reports and Review Procedures

         1.       Review and reassess the adequacy of this Charter annually and
                  report to the Board any recommended changes to this Charter.
                  The Audit Committee shall submit the Charter to the full Board
                  for approval and have the document published at least every
                  three years in accordance with the Regulations of the
                  Securities and Exchange Commission ("SEC").

         2.       Review the Company's annual audited financial statements prior
                  to filing with, or distribution to, the SEC, any governmental
                  body, or the public, including any certification, report,
                  opinion, or review rendered by the independent auditors. The
                  review should include discussion with management and
                  independent auditors of significant issues regarding
                  accounting principles, practices, estimates and judgments.

         3.       In consultation with management and the independent auditors,
                  consider the integrity of the Company's financial reporting
                  processes and controls. Discuss significant financial risk
                  exposures and the steps management has taken to monitor,
                  control and report such exposures. The Audit Committee should
                  also review significant findings prepared by the independent
                  auditors, with management's responses, the status of
                  management's responses to previous

         recommendations from the independent auditors and the status of any
         previous instructions to management from the Audit Committee.

         4.       Review the Company's quarterly financial results prior to the
                  release of results and/or the Company's quarterly financial
                  statements prior to filing with the SEC. In connection with
                  such review, discuss with financial management and the
                  independent auditors, any significant changes to the Company's
                  accounting principles and any items required to be
                  communicated by the independent auditors in accordance with
                  AICPA SAS 61 (see item 11). The Chair of the Audit Committee
                  may represent the entire Audit Committee for purposes of these
                  reviews and discussions.

         5.       Review with independent auditors the recommendations included
                  in their management letter, if any, and their informal
                  observations regarding the competence and adequacy of
                  financial and accounting procedures of the Company. On the
                  basis of this review, make recommendations to the Board for
                  any changes that seem appropriate.

         Independent auditors

         6.       Subject to any action that may be taken by the full Board,
                  have the ultimate authority and responsibility to select,
                  evaluate, and, where appropriate replace the independent
                  auditors, thus making the independent auditors ultimately
                  accountable to the Audit Committee and the Board as
                  representatives of the stockholders.

         7.       Review the performance of, and approve the fees and other
                  significant compensation to be paid to, the independent
                  auditors' firm.

         8.       On an annual basis, ensure its receipt from the independent
                  auditors of a formal written statement delineating all
                  relationships between the independent auditors and the Company
                  consistent with Independence Standards Board Standard 1, and
                  actively engage in a dialogue with the independent auditors
                  with respect to any disclosed relationships or services that
                  may impact the auditors' objectivity and independence.

         9.       Take, or recommend that the full Board take, appropriate
                  action to oversee the independence of the independent
                  auditors.

         10.      Review the independent auditors audit plan -- discuss scope,
                  staffing, locations, reliance upon management, and internal
                  audit and general audit approach.

         11.      Prior to releasing the year-end results, discuss the results
                  of the audit with the independent auditors. Discuss certain
                  matters required to be communicated to audit committees in
                  accordance with AICPA SAS 61.


                                      B-4

         12.      Consider the independent auditors' judgments about the quality
                  and appropriateness of the Company's accounting principles as
                  applied in its financial reporting.

         Legal Compliance

         13.      On at least an annual basis, review with the Company's counsel
                  any legal matters that could have a significant impact on the
                  Company's financial statements, the Company's compliance with
                  applicable laws and regulations, and inquiries received from
                  regulators or governmental agencies.

         Other Matters

         14.      Annually prepare a report to stockholders as required by the
                  SEC. The report should be included in the Company's annual
                  proxy statement.

         15.      Perform any other activities consistent with this Charter, the
                  Company's by-laws, and governing law, as the Audit Committee
                  or the Board deems necessary or appropriate.

         16.      Review financial and accounting personnel succession planning
                  with the Company.

         17.      Annually review policies and procedures as well as audit
                  results associated with directors' and officers' expense
                  accounts and perquisites. Annually review a summary of
                  directors' and officers' related party transactions and
                  potential conflicts of interest.

         18.      Annually consult with the independent auditors out of the
                  presence of management about internal controls and the
                  fullness and accuracy of the organization's financial
                  statements.

         19.      Maintain minutes of meetings and periodically report to the
                  Board on significant results of the foregoing activities.
