                            CARRIZO OIL & GAS, INC.
                        14701 ST. MARY'S LANE, SUITE 800
                              HOUSTON, TEXAS 77079

                                PROXY STATEMENT

     This Proxy Statement is furnished in connection with the solicitation of
proxies by the Board of Directors of Carrizo Oil & Gas, Inc., a Texas
corporation (the "Company"), to be voted at the 2003 Annual Meeting of
Shareholders (the "Annual Meeting") to be held at the Omni Houston Hotel
Westside, 13210 Katy Freeway, Houston, Texas on Friday, May 23, 2003, at 10:00
a.m., and any and all adjournments thereof.

     This statement and the accompanying form of proxy are first being mailed to
shareholders on or about the week of April 22, 2003. In addition to the
solicitation of proxies by mail, regular officers and employees of the Company
may, without additional compensation, solicit the return of proxies by mail,
telephone, telegram or personal contact. The Company will pay the cost of
soliciting proxies in the accompanying form. The Company will reimburse brokers
or other persons holding stock in their names or in the names of their nominees
for their reasonable expenses in forwarding proxy material to beneficial owners
of stock.

VOTING SECURITIES

     Shareholders of record as of April 11, 2003, the record date for
determining persons entitled to notice of, and to vote at, the Annual Meeting,
are entitled to vote on all matters at the Annual Meeting and at any
adjournments thereof. On that date, the issued and outstanding capital stock of
the Company consisted of 14,200,716 shares of Common Stock, par value $0.01 per
share (the "Common Stock") and approximately 65,294 shares of Series B
Convertible Participating Preferred Stock, par value $0.01 per share (the
"Series B Preferred Stock"). No other class of stock is outstanding. Each share
of Common Stock is entitled to one vote on each matter submitted to a vote of
shareholders. The Series B Preferred Stock will not be entitled to vote at the
Annual Meeting and generally has no right to vote for directors or on other
matters except in certain specified circumstances or as required by law.
Cumulative voting is not allowed. The holders of a majority of the shares
entitled to vote at the Annual Meeting, represented in person or by proxy,
constitute a quorum for the transaction of business at the Annual Meeting.

     All duly executed proxies received prior to the Annual Meeting will be
voted in accordance with the choices specified thereon and, in connection with
any other business that may properly come before the meeting, in the discretion
of the persons named in the proxy. As to any matter for which no choice has been
specified in the proxy, the shares represented thereby will be voted by the
persons named in the proxy, to the extent applicable, (1) for the election as a
director of each nominee listed herein; (2) for the approval of an amendment to
the Incentive Plan to provide for additional stock option grants to the chairman
and members of certain committees of the Board of Directors; (3) for the
appointment of Ernst & Young LLP as independent public accountants of the
Company for the fiscal year ending December 31, 2003; and (4) in the discretion
of the persons named in the proxy in connection with any other business that may
properly come before the meeting. A shareholder giving a proxy may revoke it at
any time before it is voted at the Annual Meeting by delivering written notice
to the Secretary of the Company or by delivering a properly executed proxy
bearing a later date. A shareholder who attends the Annual Meeting may, if he or
she wishes, vote by ballot at the Annual Meeting and that vote will cancel any
proxy previously given. Attendance at the Annual Meeting will not in itself,
however, constitute the revocation of a proxy.

     Proxies indicating shareholder abstentions will be counted for purposes of
determining whether there is a quorum at the Annual Meeting, but will not be
voted on any matter and therefore will have the same effect as a vote against a
matter, except in the case of director elections, which are determined by a
plurality of votes cast, as to which those abstentions will have no effect.
Shares represented by "broker nonvotes" (i.e., shares held by brokers or
nominees for which instructions have not been received from the beneficial
owners or persons entitled to vote and for which the broker or nominee does not
have discretionary power to vote on a particular matter) will be counted for
purposes of determining whether there is a quorum at the Annual Meeting, but
will not be voted on any matter, and thus will be disregarded in the calculation
of "votes cast"


with respect to that matter (even though those shares may be considered as
entitled to vote or be voted on other matters). Votes cast by proxy or in person
at the Annual Meeting will be counted by the persons appointed as election
inspectors for the Annual Meeting.

SECURITY OWNERSHIP OF MANAGEMENT AND CERTAIN BENEFICIAL OWNERS

     The table below sets forth information concerning (i) the only persons
known by the Company, based on statements filed by such persons pursuant to
Section 13(d) or 13(g) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), to own beneficially in excess of 5% of the Common Stock as of
March 15, 2003, and (ii) the shares of Common Stock beneficially owned, as of

                             ELECTION OF DIRECTORS

     The persons designated as proxies in the enclosed proxy card intend, unless
the proxy is marked with contrary instructions, to vote for the following
nominees as directors to serve until the 2004 Annual Meeting of Shareholders and

Paul B. Loyd, Jr.; Mr. Bryan R. Martin; Mr. Christopher C. Behrens and Mr. F.
Gardner Parker. The Board of Directors has no reason to believe that any nominee
for election as a director will not be a candidate or will be unable to serve,
but if for any reason one or more of these nominees is unavailable as a
candidate or unable to serve when election occurs, the persons designated as
proxies in the enclosed proxy card, in the absence of contrary instructions,
will in their discretion vote the proxies for the election of any of the other
nominees or for a substitute nominee or nominees, if any, selected by the Board
of Directors. The affirmative vote of a plurality of the votes cast by holders
entitled to vote in the election of directors at the Annual Meeting is required
for the election of each nominee for director.

COMPENSATION OF NON-EMPLOYEE DIRECTORS

     Directors not employed by the Company or any of its subsidiaries ("Outside
Directors") received an annual retainer of $7,500 through December 31, 1998.
Effective January 1, 1999, the Board of Directors suspended the payment of the
retainer. Effective January 1, 2001, the Compensation Committee proposed and the
Board of Directors approved a $1,000 per year annual retainer to be paid to each
Outside Director plus compensation of $3,000 per Board of Directors' meeting
attended ($1,000 if attended via telephone) and $500 per committee meeting
attended ($250 if attended via telephone). In April 2003, the Board of
Directors, effective for the 2002-2003 director term, approved an additional
retainer of $5,000 per annual director term for the Chairman of the Compensation
Committee and an additional retainer of $10,000 per annual director term for the
Chairman of the Audit Committee. On February 19, 2003, the Company's Incentive
Plan (the "Incentive Plan") was amended to provide for a one-time grant of
options to purchase 25,000 shares of
                                        5


Common Stock to Mr. Parker at a price of $4.65 per share, the fair market value
at the date of grant, as compensation for serving as the Chairman of the Audit
Committee. Directors who are also employees of the Company receive no payment
for serving as directors. All directors are reimbursed for travel and lodging
expenses of attending meetings. Under the Incentive Plan, Messrs. Webster,
Hamilton and Loyd, the then-current Outside Directors, were granted options to
purchase 10,000 shares of Common Stock at an exercise price per share of $11.00
in connection with the Company's initial public offering in August 1997 (the
"IPO"). Thereafter, each additional Outside Director was automatically granted
nonqualified options to purchase 10,000 shares of Common Stock on the date that
person first became an Outside Director of the Company. On March 27, 2002
options to purchase 10,000 shares were granted to Mr. Martin at a price of
$5.3650 per share, the fair market value on the date of grant. In addition, each
Outside Director serving on the day after the date of the annual meeting of
shareholders will automatically be granted options to purchase an additional
2,500 shares of Common Stock, subject to the availability for issuance of those
shares under the Incentive Plan. During the fiscal year ended December 31, 2002,
options to purchase 2,500 shares were granted to each of Messrs. Hamilton, Loyd,
Parker, Martin and Behrens at an exercise price per share of $4.78. Each option
granted to an Outside Director will (i) have a ten-year term, (ii) have an
exercise price equal to the fair market value of a share of Common Stock on the
date of grant and (iii) become exercisable in cumulative annual increments of
one-third of the total number of shares of Common Stock subject thereto,
beginning on the first anniversary of the date of grant.

     The Board of Directors has recommended the following changes to the
Incentive Plan, subject to shareholder approval:

     - the Chairman of the Audit Committee and the Chairman of the Compensation
       Committee will automatically be granted additional options to purchase
       3,000 and 2,000 shares of Common Stock, respectively, on the first
       business day following the date on which each annual meeting of the
       Company's shareholders is held; and

     - the Board of Directors may, in its discretion, grant options to purchase
       of up to 3,000 shares and up to 2,000 shares, respectively, on the date
       specified above to non-chairmen members of the audit and compensation
       committees who are deemed by the Committee to be "independent" for
       purposes of the rules of the Nasdaq Stock Market.

     If approved by shareholders, these grants could be made to the chairman or
a member of the Audit Committee or Compensation Committee, respectively,
notwithstanding that the same person may also receive grants as a chairman or
member of the Compensation Committee or Audit Committee, respectively. See
"Proposal 2 -- Proposal to Amend Incentive Plan to Provide Additional Stock
Option Grants to the Chairman and Members of Certain Committees of the Board of
Directors."

BOARD OF DIRECTORS AND COMMITTEES OF THE BOARD

     The Board of Directors of the Company held four meetings during the fiscal
year ended December 31, 2002, and transacted business on 10 occasions during the
fiscal year by unanimous written consent.

     The Board of Directors has an Audit Committee which, during the fiscal year
ended December 31, 2002, consisted of Messrs. Loyd, Parker and Martin. The
function of the Audit Committee is to meet with the internal financial staff of
the Company and the independent public accountants engaged by the Company to
review (i) the scope and findings of the annual audit, (ii) quarterly financial
statements, (iii) accounting policies and procedures and the Company's financial
reporting, and (iv) the internal controls employed by the Company. The Audit
Committee also recommends to the Board of Directors the independent public
accountants to be selected to audit the Company's annual financial statements,
and reviews the fees charged for audits and for any nonaudit engagements. The
Committee's findings and recommendations are reported to management and the
Board of Directors for appropriate action. The Audit Committee met five times
during fiscal 2002.

     The rules of the Nasdaq Stock Market restrict directors who have
relationships with the Company that may interfere with the exercise of their
independence from management and the Company from serving on the

                                        6


audit committee. We believe that the members of the Audit Committee, other than
possibly Mr. Martin, have no such relationships and are therefore independent
for purposes of current Nasdaq Stock Market rules. The applications of the
Nasdaq Stock Market rules to Mr. Martin is not clear, but it is possible that he
would be deemed not independent because he is a principal of JPMorgan Partners,
an entity which could be deemed to be an affiliate of the Company. The Board of
Directors appointed Mr. Martin to the audit committee because of his experience
in the field of finance and because the Company is contractually obligated to
appoint a nominee of JPMorgan Partners to the audit committee under the terms of
the 1999 Shareholders Agreement. The Board of Directors believes that the
appointment of Mr. Martin is required by the best interests of the Company and
its shareholders.

     The Board of Directors has a Compensation Committee which, during the
fiscal year ended December 31, 2002, consisted of Messrs. Parker, Hamilton and
Behrens. The function of the Compensation Committee is to consider and act upon
management's recommendations to the Board of Directors on salaries, bonuses and
other forms of compensation for the Company's executive officers and certain
other key employees. The Compensation Committee has been appointed by the Board
of Directors to administer the Company's stock option plans (subject in some
cases to action by the full Board). The Compensation Committee held one meeting
during fiscal 2002.

     The Board of Directors has a Budget Committee, consisting of Mr. Johnson
and Mr. Wojtek, whose function is to consider matters relating to the Company's
drilling program and the Company's budget and related matters. The Budget
Committee's actions are advisory only and not binding on the Board unless the
Board decides otherwise.

     The Board of Directors does not have a standing Nominating Committee.

     On December 5, 2001, the Board of Directors established an independent
Special Financing Committee to evaluate the terms of any financing proposals
which the Company may be considering and in which other company shareholders may
participate. The Special Committee held two meetings during fiscal 2002.

     During the fiscal year ended December 31, 2002, each director attended at
least 75% of the aggregate of the total number of Board of Directors meetings
and of meetings of committees of the Board of Directors on which he served,
except Mr. Martin.

SECTION 16(a) REPORTING DELINQUENCIES

     Section 16(a) of the Exchange Act requires that the Company's executive
officers and directors, and persons who own more than 10% of a registered class
of the Company's equity securities, file reports of ownership and changes of
ownership with the Securities and Exchange Commission (the "SEC"). Officers,
directors and greater than 10% shareholders are required by SEC regulation to
furnish the Company with copies of all such forms they file.

     Based solely on its review of the copies of such forms received by the
Company, and on written representations by the Company's officers and directors
regarding their compliance with the filing requirements, the Company believes
that during the fiscal year ended December 31, 2002, all reports required by
Section 16(a) to be filed by its directors, officers and greater than 10%
beneficial owners were filed on a timely basis.

COMPENSATION OF EXECUTIVE OFFICERS

     The following table sets forth the annual, long-term and total compensation
for (i) the Company's Chief Executive Officer for the fiscal years ended
December 31, 2002, 2001 and 2000, (ii) its other four executive officers, and
(iii) one other individual who served as an executive officer in 2002, for the
fiscal years ended December 31, 2002, 2001 and 2000 (collectively, the "Named
Executives").

    the underlying security (based upon the value of the Common Stock on the
    date of grant) appreciates at annualized rates of 5% and 10% over the term
    of the award. Actual gains, if any, on stock option exercises are dependent
    on the future performance of Common Stock and overall market conditions.
    There can be no assurance that the amounts reflected on this table will be
    achieved.

(1) Value realized is calculated based on the difference between the option
    exercise price and the closing market price of the Company's Common Stock on
    the date of exercise, multiplied by the number of shares underlying the
    options.

(2) Value of unexercised in-the-money options is calculated based upon the
    difference between the option price and the closing price of the Company's
    Common Stock at fiscal year-end, multiplied by the number of shares
    underlying the options. The closing price of the Company's Common Stock, as
    reported on the Nasdaq Stock Market on December 31, 2002, was $5.27.

CERTAIN TRANSACTIONS

     On February 20, 2002, the Company consummated the transactions (the "2002
Financing") contemplated by a Securities Purchase Agreement dated February 20,
2002 (the "2002 Securities Purchase Agreement") among the Company, Mellon
Ventures, L.P. ("Mellon") and Steven A. Webster (excluding the Company, the
"2002 Investors"). Such transactions included (i) the payment by the 2002
Investors of an

                                        9


aggregate purchase price of $6,000,000, (ii) the sale of 60,000 shares of Series
B Convertible Participating Preferred Stock (the "Series B Preferred Stock") the
terms of which are set forth in the Statement of Resolution Establishing Series
of Shares designated Series B Convertible Participating Preferred Stock (the
"Statement of Resolution") and which include the right to convert such shares
into Common Stock, par value $0.01 (the "Common Stock") of the Company (the
"Underlying Shares") at a price of $5.70 per share, subject to adjustments, to
the 2002 Investors pursuant to the terms of the 2002 Securities Purchase
Agreement and (iii) the sale of warrants (the "2002 Warrants") to purchase up to
252,632 shares of the Company's Common Stock (the "2002 Warrant Shares") at the
exercise price of $5.94 per share, subject to adjustments, to the 2002 Investors
pursuant to the terms of Warrant Agreement dated February 20, 2002 (the "2002
Warrant Agreement") among the Company, Mellon and Steven A. Webster, (iv) the
execution of the Shareholders Agreement dated February 20, 2002 (the "2002
Shareholders Agreement") among the Company, Mellon, Paul B. Loyd, Jr., Douglas
A.P. Hamilton, Steven A. Webster, S.P. Johnson IV, Frank A. Wojtek and DAPHAM
Partnership, L.P., (v) the execution of the Registration Rights Agreement dated
February 20, 2002 ("2002 Registration Rights Agreement") among the Company,
Mellon and Steven A. Webster and (vi) the execution of a Compliance Sideletter
dated as of February 20, 2002 by and between the Company and Mellon (the "2002
Compliance Sideletter"). The Company sold $4.0 million and $2.0 million of
Series B Preferred Stock and 168,422 and 84,210 Warrants to Mellon and Mr.
Webster, respectively.

     The Statement of Resolution establishes a series of 150,000 shares (60,000
of which were issued to the 2002 Investors under the 2002 Securities Purchase
Agreement and approximately 65,294 of which are currently outstanding) of the
Company's preferred stock, designated as Series B Convertible Participating
Preferred Stock with designations, preferences, limitations and relative rights,
voting, redemption and other rights that include the following:

     Dividends.  Holders of Series B Preferred Stock are entitled to receive
cumulative dividends on each share of Series B Preferred Stock, payable
semi-annually. Dividends will be paid, at the option of the Company, (i) in cash
at the rate of $8.00 per year or (ii) by issuing additional shares of Series B
Preferred Stock at the annual rate of 0.10 of a share of Series B Preferred
Stock on each share of Series B Preferred Stock as converted. In addition to the
foregoing, if the Company declares a cash dividend on the Common Stock of the
Company, the holders of shares of Series B Preferred Stock shall be entitled to
receive cash dividends on an "as converted" basis. Unless all accrued dividends
on the Series B Preferred Stock shall have been paid, distributions and
redemptions on any Junior Stock (as defined below) are restricted.

     Redemption.  The Series B Preferred Stock is required to be redeemed by the
Company at any time after the third anniversary of the initial issuance of the
Series B Preferred Stock (the "Issue Date") upon 90 days prior written request
from any holder at a price per share equal to Purchase Price/Dividend Preference
(as defined below). The Company may redeem the Series B Preferred Stock at
varying prices ranging from 120% of the Purchase Price/Dividend Preference to,
in the case of redemptions after the third anniversary of the Issue Date, a
price per share equal to the Purchase Price/Dividend Preference. "Purchase
Price/Dividend Preference" is defined to mean $100 plus all cumulative and
accrued dividends (whether or not earned or declared) accumulated and unpaid on
such share of Series B Preferred Stock, through the date the Company has paid or
properly provided for the Redemption Price.

     Voting.  Holders of the Series B Preferred Stock generally have no right to
vote for directors or on other matters except in certain circumstances described
herein or as otherwise required by law.

     The holders of Series B Preferred Stock have the right to approve, by the
affirmative vote of the holders of a majority of the outstanding shares of
Series B Preferred Stock, (i) the creation, authorization or issuance, or any
corporate transaction such as a merger or consolidation that results in the
creation or issuance of, any class or series of stock ranking senior to the
Series B Preferred Stock ("Prior Stock") or ranking on a parity with the Series
B Preferred Stock ("Parity Stock"); (ii) any corporate transaction such as a
merger or consolidation, or any amendment to the Articles of Incorporation, that
would result in (A) an increase or decrease of the aggregate number of
authorized shares of Series B Preferred Stock, or (B) a change in the
designations, preferences, limitations or relative rights of the shares of
Series B Preferred Stock; (iii) any change in the Company's Articles of
Incorporation or bylaws, as then in effect, that adversely affects the

                                        10


rights, preferences or privileges of the Series B Preferred Stock; (iv) any
material change in the nature of the Company's business; or (v) certain issuance
of any shares of Series B Preferred Stock.

     Holders of Series B Preferred Stock also have the right to vote as a class
in a number of other circumstances as are required by the Texas Business
Corporation Act ("TBCA"). Under the 2002 Shareholders Agreement, the holders of
the Series B Preferred Stock have agreed to vote such shares in favor of certain
of these actions.

     The terms of the Series B Preferred Stock, including the voting rights
thereof, could have the effect of delaying, deferring or preventing a takeover
attempt of the Company.

     Liquidation.  In the event of any voluntary or involuntary dissolution,
liquidation or winding up or a Sale (as defined below) of the Company (a
"Liquidation"), before any distribution of assets is made to the holders of any
Junior Stock of the Company, the holder of each share of Series B Preferred
Stock then outstanding will be entitled to be paid out of the assets of the
Company available for distribution to its shareholders, the greater of the
following amounts per share of Series B Preferred Stock: (i) $100 in cash plus
all cumulative and accrued dividends (whether or not earned or declared)
accumulated and unpaid on such share, through the date fixed for the
distribution of assets of the Company to the holders of Series B Preferred
Stock, or (ii) the liquidation distribution, if any, payable in such Liquidation
with respect to each share of Common Stock distributed pro rata to the holders
of the Series B Preferred Stock, any Parity Stock and the Common Stock on an
as-converted basis (assuming the conversion of all Series B Preferred Stock and
Parity Stock (if convertible into Common Stock) at the time such liquidation
distribution is paid to a holder of such Common Stock). For purposes hereof,
"Sale" shall mean and shall be deemed to have occurred at such time as any of
the following occurs: (x) certain mergers that constitute a "Change of Control"
(as defined herein); or (y) the sale, transfer or other disposition by the
Company of all or substantially all of the assets of the Company to another
entity.

     Conversion.  The holders of the Series B Preferred Stock have the right, at
each holder's option, to convert all or a portion of such Series B Preferred
Stock into the number of fully paid and nonassessable shares of Common Stock
(calculated as to each conversion to the nearest 1/100th of a share) obtained by
dividing (i) the product of (A) $100 plus all cumulative and accrued dividends
(whether or not earned or declared) accumulated and unpaid on such share through
the date of surrender of such share of Series B Preferred Stock multiplied by
(B) each share of Series B Preferred Stock to be converted by (ii) the
Conversion Price (as defined below). "Conversion Price" is defined to mean the
conversion price per share of the Common Stock into which the Series B Preferred
Stock is convertible, as such Conversion Price may be adjusted pursuant to the
Statement of Resolution. The initial Conversion Price is $5.70. The Conversion
Price is subject to adjustment in certain circumstances.

     Change of Control.  Upon the occurrence of certain events constituting a
"Change of Control", the Company is required to make an offer to each holder of
Series B Preferred Stock to repurchase all or any part of such holder's Series B
Preferred Stock at an offer price per share of Series B Preferred Stock in cash
equal to 105% of the Change of Control Purchase Price (as defined below)
including (a) any persons becoming the beneficial owners of more than 50% of the
Company; (b) during any period of two consecutive years, a majority of the Board
of Directors changes; (c) the merger or consolidation of the Company except for
certain mergers or consolidations in which the shareholders of the Company prior
to the transaction retain a majority of the voting stock of the surviving
entity; and (d) the sale of all or substantially all of the assets of the
Company, subject to certain exceptions for the foregoing matters. "Change of
Control Purchase Price" is defined to mean $100 plus all cumulative and accrued
dividends (whether or not earned or declared) accumulated and unpaid on such
share of Series B Preferred Stock through the date of payment of the Change of
Control Purchase Price.

     Ranking and Certain Covenants.  The Series B Preferred Stock ranks senior
to the Common Stock and all other series of the Company's preferred stock (none
of which are issued and outstanding as of the date hereof) as to the payment of
dividends, as to payments upon redemption and as to the distribution of assets
upon liquidation, dissolution or winding up unless, after the approval of the
holders of a majority of the shares of Series B Preferred Stock, the terms of
such other series provide otherwise.
                                        11


     2002 Shareholders Agreement.  The 2002 Shareholders Agreement provides that
if the holders of at least 51% of the Common Stock then outstanding approve a
merger, Sale (as defined in the 2002 Shareholders Agreement) of the Company or
sale of all or substantially all of the assets of the Company (an "Approved
Sale"), each holder of Series B Preferred Stock will consent to, vote for and
raise no objection against the Approved Sale as a holder of Series B Preferred
Stock if the consummation of such Approved Sale will constitute a Change of
Control (as defined above) or the Approved Sale is a reincorporation merger,
subject to certain conditions.

     If S.P. Johnson IV, Frank A. Wojtek, Paul B. Loyd, Jr., Douglas A.P.
Hamilton, Steven A. Webster, DAPHAM Partnership L.P. or certain transferees
thereof (each a "Founder Shareholder") desires to make certain transfers of
shares of Common Stock that are not Public Sales (as determined in the 2002
Shareholders Agreement), such Founder Shareholder must allow Mellon "tag-along
rights" whereby Mellon has the option also to include shares in the transfer.

     Under the 2002 Shareholders Agreement, the Company has granted to Mellon
and Mr. Webster preemptive rights to purchase certain (i) equity securities,
(ii) debt securities, (iii) options, warrants and other rights to acquire each
of such securities and (iv) common stock equivalents convertible into or
exchangeable for equity securities issuable by the Company, subject to certain
exclusions.

     The preemptive rights and tag-along rights under the 2002 Shareholders
Agreement terminate upon the first to occur of (a) notice of termination by
holders of 50% of the Common Stock issuable upon conversion of the Series B
Preferred Stock and exercise of the 2002 Warrants, (b) certain sale transactions
involving the Company or (c) the time Mellon (or certain of its transferees)
owns less than 50% of the shares issuable upon conversion of the Series B
Preferred Stock and exercise of the 2002 Warrants.

     2002 Warrants.  The 2002 Warrants are exercisable at any time prior to the
expiration date on February 20, 2007 for the purchase of an aggregate of 252,632
shares of Common Stock at an exercise price of $5.94 per share, subject to
certain adjustments.

     The 2002 Registration Rights Agreement provides registration rights with
respect to the shares of Common Stock issuable upon the conversion of the Series
B Preferred Stock and the exercise of the 2002 Warrants held by Mellon and Mr.
Webster (the "2002 Investor Registrable Securities"). The Company may be
required to effect one demand registration, subject to certain conditions and
limitations. The holders of the registration rights also have limited rights to
require the Company to include their shares of Common Stock in connection with
certain other offerings registered by the Company.

  Repurchase of Preferred Stock

     On December 15, 1999, the Company consummated the transactions (the "Enron
Repurchase") contemplated by the Stock and Warrant Purchase Agreement dated
December 1, 1999 ("Enron Purchase Agreement") among the Company and Enron North
America Corp. ("ENA"), Joint Energy Development Investments II Limited
Partnership ("JEDI II") and Sundance Assets, L.P. ("Sundance") (ENA, JEDI II and
Sundance, collectively, the "Enron Parties"). Such transactions included (i) the
payment to the Enron Parties of an aggregate purchase price of $12,000,000 and
other fees, (ii) the repurchase of all the outstanding shares of the Company's
9% Series A Preferred Stock, (iii) the repurchase of 750,000 previously
outstanding warrants to purchase the Company's Common Stock held by the Enron
Parties and (iv) the amendment of the terms of 250,000 warrants (the "Retained
Enron Warrants") to purchase the Company's Common Stock retained by the Enron
Parties. The exercise price of the Retained Enron Warrants was reduced from
$11.50 per share to $4 per share as contemplated by the Enron Purchase
Agreement.

  Sale of Common Stock, Notes and Warrants

     Also on December 15, 1999, the Company consummated the transactions (the
"1999 Financing") contemplated by a Securities Purchase Agreement dated December
15, 1999 (the "1999 Securities Purchase Agreement") among the Company, CB
Capital Investors, L.P. ("Chase") (now JPMorgan Partners (23A SBIC), LLC),
Mellon Ventures, L.P. ("Mellon"), Paul B. Loyd, Jr., Douglas A.P. Hamilton and
Steven A.

                                        12


Webster (excluding the Company, the "Investors"). Such transactions included (i)
the payment by the Investors of an aggregate purchase price of $30,000,000, (ii)
the sale of an aggregate of $22,000,000 principal amount of 9% Senior
Subordinated Notes due 2007 (the "Notes") to the Investors, (iii) the sale of an
aggregate of 3,636,364 shares of the Company's Common Stock for $2.20 per share
to the Investors, (iv) the sale of warrants (the "Warrants") to purchase up to
2,760,189 shares of the Company's Common Stock (the "Warrant Shares") at the
exercise price of $2.20 per share, subject to adjustments, to the Investors, (v)
the execution of the Shareholders Agreement dated December 15, 1999 (the "1999
Shareholders Agreement") among the Company, Chase, Mellon, Paul B. Loyd, Jr.,
Douglas A.P. Hamilton, Steven A. Webster, S.P. Johnson IV, Frank A. Wojtek and
DAPHAM Partnership, L.P., (vi) the execution and delivery of the Warrant
Agreement dated December 15, 1999 (the "Warrant Agreement") among the Company,
Chase, Mellon, Paul B. Loyd, Jr., Douglas A.P. Hamilton and Steven A. Webster,
(vii) the execution of the Registration Rights Agreement dated December 15, 1999
("Chase Registration Rights Agreement") among the Company, Chase and Mellon,
(viii) the execution of the Amended and Restated Registration Rights Agreement
dated December 15, 1999 ("Amended Founders Registration Rights Agreement") among
the Company, Paul B. Loyd, Jr., Douglas A.P. Hamilton, Steven A. Webster, S.P.
Johnson IV, Frank A. Wojtek and DAPHAM Partnership, L.P., and (ix) the execution
of a Compliance Sideletter dated December 15, 1999 among the Company, Chase and
Mellon (the "1999 Compliance Sideletter"). The Company sold $17.6 million, $2.2
million, $0.8 million, $0.8 million and $0.8 million principal amount of Notes;
2,909,091, 363,636, 121,212, 121,212 and 121,212 shares of the Company's common
stock and 2,208,151, 276,019, 92,006, 92,006 and 92,006 Warrants to Chase,
Mellon, Mr. Loyd, Mr. Webster and Mr. Hamilton, respectively.

     In addition to providing for the foregoing transactions, the 1999
Securities Purchase Agreement provides that the Notes will be subordinated and
subject in right of payment to the prior payment of the senior indebtedness of
the Company, which includes but is not limited to certain indebtedness under the
Company's senior credit facility with Compass Bank, certain indebtedness
incurred pursuant to borrowing base limitations supported by the Company's oil
and gas properties, certain purchase money indebtedness issued or incurred to
finance consolidated capital expenditures, and certain indebtedness incurred
pursuant to the financing of certain acquisitions or the development of the
Company's oil and gas properties with proved reserves.

     The Warrants are exercisable at any time prior to the expiration date on
December 15, 2007 for the purchase of an aggregate of 2,760,189 shares of Common
Stock at an exercise price of $2.20 per share, subject to certain adjustments.

     Each Warrant may be exercised by cash payment or on a "cashless basis" by
utilizing the average market price during the four-day trading period preceding
the date of exercise.

     The number and kind of Warrant Shares issued and the exercise price are
subject to adjustment in certain circumstances, including (a) if the Company
pays a dividend in Common Stock or distributes shares of its Common Stock,
subdivides, splits or reclassifies its outstanding shares of Common Stock into a
larger number of shares of Common Stock, or combines its outstanding shares of
Common Stock into a smaller number of shares of Common Stock, (b) if the Company
issues shares of Common Stock or securities exercisable or exchangeable for or
convertible into shares of Common Stock for no consideration or for less than
the market value (as specified in the Warrant) of the Common Stock, subject to
certain exceptions, (c) if the Company distributes any of its equity securities
(other than Common Stock or options) to the holders of the Common Stock on a pro
rata basis, (d) if the Company engages in a consolidation, merger or business
combination, sells all of its assets to another person or entity, or enters into
certain capital reorganizations or reclassifications of the capital stock of the
Company or (e) the Company takes certain other actions affecting its Common
Stock.

     Chase required that the Company's outside directors, Messrs. Loyd, Hamilton
and Webster, invest an aggregate of at least $3,000,000 in the Financing and
each invested $1,000,000 in the 1999 Financing. As part of the Financing, an
aggregate fee of $405,000 was paid to Chase and Mellon.

     Of the approximately $29,000,000 net proceeds of the Financing, $12,060,000
was used to fund the Enron Repurchase and related expenses, $2,025,000 was used
to repay a bridge loan extended to the Company by its
                                        13


outside directors, $3,000,000 was used to repay other indebtedness, and the
Company expects the remaining proceeds to be used to fund the Company's ongoing
exploration and development program and general corporate purposes.

     Under the 1999 Shareholders Agreement each of S.P. Johnson IV, Frank A.
Wojtek, Paul B. Loyd, Jr., Douglas A.P. Hamilton, Steven A. Webster, DAPHAM
Partnership, L.P., Chase and Mellon (the "Shareholders") have agreed not to
transfer shares of the Common Stock or the Warrants to a competitor of the
Company and have agreed to cause certain transferees to be bound by the
Shareholders Agreement.

     The 1999 Shareholders Agreement provides that so long as Chase owns at
least 15% of the Common Stock of the Company (with percentage ownerships being
determined as specified in the 1999 Shareholders Agreement), the Shareholders
agree to vote their shares to cause the number of directors constituting the
Board of Directors to be seven and to cause the election of two directors to be
nominated by Chase. The Shareholders have agreed, so long as Chase owns at least
7.5% of the Common Stock (with percentage ownerships being determined as
specified in the 1999 Shareholders Agreement) of the Company but less than 15%,
to vote their shares to cause the number of directors constituting the Board of
Directors to be seven and to cause the election of one director to be nominated
by Chase. The Shareholders have also agreed if at any time after December 15,
2004, Chase then owns at least 15% of the Common Stock (with percentage
ownerships being determined as specified in the 1999 Shareholders Agreement)
that, unless there shall have occurred certain completed or proposed sale
transactions involving the Company or there has occurred a specified minimum
public float of Common Stock, then Chase has the right to designate two
additional members to the Board and the size of the Board shall be increased
accordingly. The Shareholders have agreed to vote their shares in accordance
with such arrangement. The Company, upon Board approval, was entitled to
increase the size of the Board by one additional member at any time after the
first shareholders meeting following the Financing, and, as such, approved the
addition to the Board of Mr. Parker in fiscal 2000. If the Company at any other
time increases the size of the Board of Directors, the Shareholders have agreed
to take action, including the voting of their securities, to cause to be elected
the number of directors nominated by Chase necessary to maintain the applicable
proportion of directors nominated by Chase to the Board of Directors.

     Pursuant to the 1999 Shareholders Agreement, Messrs. Christopher Behrens
and Arnold Chavkin were appointed to the Company's Board of Directors. Upon Mr.
Chavkin's resignation from the Board of Directors of the Company effective March
2002, JPMorgan Partners designated Bryan R. Martin as his replacement, and Mr.
Martin was appointed to the Board of Directors.

     For so long as Chase is entitled to designate a director, at least one such
director is required to be a member of each committee of the Company's Board of
Directors and the board of directors of any subsidiary of the Company. The
Company has, in connection with the Shareholders Agreement, established a Budget
Committee of the Board of Directors that will consider matters relating to the
Company's drilling program, the Company's budget and related matters. In certain
circumstances in which Chase is entitled to name a director and such
directorship is vacant, Chase may instead appoint one or more Board observers in
lieu of directors.

     The Company agreed in the 1999 Shareholders Agreement to limit the maximum
number of common stock equivalents issuable under the Company's equity incentive
plans to 2.5 million shares and equivalents (including any shares and
equivalents issued or issuable as of the date of the 1999 Shareholders
Agreement).

     The Shareholders have also agreed in the 1999 Shareholders Agreement to
cooperate with the Company in complying with the terms of the 1999 Compliance
Sideletter (described below), including by voting in favor of actions taken to
remedy certain regulatory problems.

     If S.P. Johnson IV, Frank A. Wojtek, Paul B. Loyd, Jr., Douglas A.P.
Hamilton, Steven A. Webster, DAPHAM Partnership L.P. or certain transferees
thereof (each a "Founder Shareholder") desires to make certain transfers of
shares of Common Stock that are not Public Sales (as determined in the 1999
Shareholders Agreement), such Founder Shareholder must allow Mellon and any
Shareholder who holds at least 10% of the Common Stock of the Company and is not
a Founder Shareholder (collectively, the "Significant

                                        14


Shareholders") the option also to include shares in the transfer. If the
prospective transferee is unwilling or unable to acquire all such shares, then
the transferring Founder Shareholder may either cancel the proposed transfer or
allocate on a proportional basis the number of shares the prospective transferee
is willing to acquire among the transferring Founder Shareholder and the
Significant Shareholders.

     Under the 1999 Shareholders Agreement, the Company has granted to the
Significant Shareholders rights to purchase certain (i) equity securities, (ii)
debt securities, (iii) options, warrants and other rights to acquire each of
such securities and (iv) common stock equivalents convertible into or
exchangeable for equity securities issuable by the Company, provided that
securities issued pursuant to equity incentive plans, securities issued in
certain public offerings, securities issued as consideration in a merger,
business combination or acquisition, certain securities issued upon conversion
of other securities, the Warrant Shares, and certain distributions of securities
are all excluded from this right.

     The 1999 Shareholders Agreement terminates upon the first to occur of (a)
notice of termination by holders of 50% of the shares held by Chase or Mellon
(and certain of their transferees), (b) certain sale transactions involving the
Company or (c) the time neither Chase nor Mellon (or certain of their
transferees) owns more than 7 1/2% of the Common Stock.

     Additional information concerning the Notes, the Warrants, the 1999
Shareholders Agreement and the transactions relating to the 1999 Securities
Purchase Agreement may be found in the Company's Current Report on Form 8-K
dated December 15, 1999, including the exhibits to that document.

     In 2000, the Company received a finder's fee valued at $1,544,180 from
affiliates of Donaldson, Lufkin & Jenrette ("DLJ") in connection with their
purchase of a significant minority shareholder interest in Michael Petroleum
Corporation ("MPC"). MPC is a privately-held exploration and production company
which focuses on the prolific gas producing Lobo Trend in South Texas. The
minority shareholder interest in MPC was purchased by entities affiliated with
DLJ. The Company elected to receive the fee in the form of 18,947 shares of
common stock, 1.9% of the outstanding common shares of MPC, which is accounted
for as a cost basis investment. Steven A. Webster, who is the Chairman of the
Board of the Company, is also the Chairman of Global Energy Partners Ltd., a
merchant banking affiliate of DLJ (now known as CSFB Private Equity) which makes
investments in energy companies, and joined the Board of Directors of MPC in
connection with the transaction. MPC could be deemed to be a competitor of the
Company.

     During the third quarter of 2001, the Company sold its interest in MPC
pursuant to an agreement between MPC and its shareholders for the sale of a
majority interest in MPC to Calpine Natural Gas Company. The Company received
total cash proceeds of $5.7 million, of which $5.5 million was paid to the
Company during the third quarter of 2001 and the balance was paid during 2002
and 2003.

     In November 1999, the Company entered into a month-to-month agreement with
San Felipe Resource Company, an entity owned by Mr. Webster, under which Mr.
Webster provides consulting services to the Company in exchange for a fee of
$9,000 per month, that was increased to $12,000 per month effective April 2003.

     On December 6, 2001 options to purchase 75,000 shares were granted under
the Incentive Plan to Mr. Webster at the price of $4.01 per share, the fair
market value on the date of the grant, for consulting services.

     In December 2001, the Company sold to Mr. Webster a 2% working interest in
certain leases in Matagorda County and the right to participate in the Staubach
#1 well located within those leases in exchange for $20,000 and the payment by
Mr. Webster of a 33% promoted interest for the drilling costs through casing
point of that well. The terms of this sale were consistent with the terms of
sales to other participants in this project.

     During the years ended December 31, 2001 and 2002, the Company participated
in the drilling of two wells and one well, respectively, that were operated by a
subsidiary of Brigham Exploration Company ("Brigham"). During the year ended
December 31, 2002, Brigham participated in the drilling of two wells operated by
the Company. Mr. Webster is a member of the Board of Directors of Brigham. Mr.
Webster is

                                        15


also a managing director of a merchant banking affiliate of the beneficial owner
of approximately 35% of the common stock of the parent company of Brigham Oil
and Gas, LP.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Company's executive compensation programs are designed to attract and
retain highly qualified executives and to motivate them to maximize shareholder
returns. The Company's executive compensation program is intended to provide
competitive compensation levels and incentive pay levels that vary based on
corporate and individual performance.

     There are three basic components to the Company's current compensation
system: base pay; annual incentive compensation in the form of a cash bonus; and
long-term equity-based incentive compensation. Each component is addressed in
the context of individual and Company performance and competitive conditions. In
determining competitive compensation levels, the Company analyzes data that
includes information regarding the general oil and natural gas exploration and
production industry.

     Actual individual awards and changes in remuneration to the individual
executives are recommended by the Compensation Committee but approved by the
Board of Directors. The Chief Executive Officer works with the Compensation
Committee in the design of the plans and makes recommendations to the Committee
regarding the salaries and bonuses of Company employees that report directly to
him. Grants or awards of stock, including stock options, are individually
determined and administered by the Compensation Committee.

     Base Pay.  Base pay is designed to be competitive with salary levels for
comparable executive positions at other oil and natural gas exploration and
production companies and the Compensation Committee reviews such comparable
salary information as one factor to be considered in determining the base pay
for the Company's executive officers. Other factors the Compensation Committee
considers in determining base pay for each of the executive officers are that
officer's responsibilities, experience, leadership, potential future
contribution, and demonstrated individual performance. The types and relative
importance of specific financial and other business objectives vary among the
Company's executives depending on their positions and the particular operations
and functions for which they are responsible. The Compensation Committee also
considers the Company's earnings levels and progress in implementing its
business strategy in establishing base salary increases for executives. The
employment contracts of the executive officers provide that base pay is to be
reviewed at least annually and will be increased at any time and from time to
time, and that any increase will be substantially consistent with increases in
base salary generally awarded in the ordinary course of business to executives
of the Company. As a result of the Company's positive financial results and
continued drilling success, each of the Named Executive's base salary was
increased by 5% effective April 1, 2003, except for Mr. Canjar, who is no longer
employed by the Company.

     Annual Bonus.  The annual bonus is determined by the Compensation
Committee. The employment contracts with the executive officers contemplate
annual bonus awards in an amount comparable to the annual bonus of other Company
executives, taking into account the individual's position and responsibilities.
The Compensation Committee chose to defer the payment of bonuses to executive
officers with respect to 2002 until 2003. Each of the Named Executives, except
Mr. Canjar, was awarded a de minimis bonus of $1,296 during 2002. As a result of
the Company's positive financial results and continued drilling success, on
April 3, 2003, bonuses in the amounts of $46,720, $8,343, $7,509, $34,000 and
$16,500 were awarded to Mr. Johnson, Mr. Wojtek, Mr. Trahan, Mr. Fisher and Mr.
Greene, respectively.

     Long-Term Equity-Based Compensation.  To date, the Company has relied
primarily upon stock option awards to provide long-term incentives for
executives. Prior to the Company's IPO, the shareholders and the Board of
Directors of the Company approved the Company's Incentive Plan. The objectives
of the Incentive Plan are to (i) attract and retain the services of key
employees, qualified independent directors and qualified consultants and other
independent contractors and (ii) encourage a sense of proprietorship in and
stimulate the active interest of those persons in the development and financial
success of the Company by making awards designed to provide participants in the
Incentive Plan with proprietary interest in the growth and performance of the
Company. Long-term equity-based compensation is tied to shareholder return.
                                        16


     Under the Company's Incentive Plan, long-term incentive compensation
consists of stock options, which generally have a ten-year term and vest in 33%
increments in each of the three years following the date of the grant. The
exercise price of stock options granted is equal to or greater than the fair
market value of the Common Stock on the date of grant; accordingly, executives
receiving stock options are rewarded only if the market price of the Common
Stock appreciates. Stock options are thus designed to align the interests of the
Company's executives with those of its shareholders by encouraging executives to
enhance the value of the Company and, hence, the price of the Common Stock and
each shareholder's return.

     On August 12, 2002, the Company granted options to purchase 25,000 shares
of Common Stock to Mr. Greene at an exercise price per share of $3.76. As a
result of the Company's positive financial results and continued drilling
success, on April 3, 2003, the Company granted options to purchase 50,000,
25,000 and 40,000 shares of Common Stock to Mr. Johnson, Mr. Fisher and Mr.
Greene, respectively, at an exercise price per share of $4.43. These options
have a ten-year term and vest in 33% increments in each of the three years
following the date of the grant.

     The Company may periodically grant new options to provide continuing
incentive for future performance. In making the decision to grant additional
options, the Compensation Committee would expect to consider factors such as the
size of previous grants and the number of options held. In determining whether
to grant executive officers stock options under the Plan, the Compensation
Committee considers factors, including that executive's current ownership stake
in the Company, the degree to which increasing that ownership stake would
provide the executive with additional incentives for future performance, the
likelihood that the grant of those options would encourage the executive to
remain with the Company and the value of the executive's service to the Company.

     Section 162(m) of the Internal Revenue Code.  Section 162(m) of the
Internal Revenue Code of 1986, as amended, generally limits (to $1 million per
covered executive) the deductibility for federal income tax purposes of annual
compensation paid to a company's chief executive officer and each of its other
four most highly compensated executive officers. The Compensation Committee and
the Board of Directors will take deductibility or nondeductibility of
compensation into account but have in the past authorized, and will retain the
discretion in the future to authorize, the payment of potentially nondeductible
amounts.

     Compensation of the Chief Executive Officer.  The Compensation Committee
based the compensation of the Company's Chief Executive Officer, Mr. Johnson, on
the same considerations described above for other executive officers. The
Compensation Committee chose to defer the payment of bonuses to executive
officers with respect to 2002 until 2003. Consistent with its decision to award
bonuses and options to acquire Company stock to the other executive officers,
the Compensation Committee awarded Mr. Johnson a de minimis bonus during 2002 of
$1,296. As a result of the Company's positive financial results and continued
drilling success, on April 3, 2003, the Company increased Mr. Johnson's salary
by 5%, awarded him a bonus of $46,720 and granted him options to purchase 50,000
shares of Common Stock.

     Executive compensation is an evolving field. The Compensation Committee
monitors trends in this area, as well as changes in law, regulation and
accounting practices, that may affect either its compensation practices or its
philosophy. Accordingly, the Committee reserves the right to alter its approach
in response to changing conditions.

S. P. Johnson IV............................................    $245,284

Frank A. Wojtek.............................................    $175,203
  Vice President and Chief Financial Officer
Jeremy T. Greene............................................    $173,250

Kendall A. Trahan...........................................    $157,683
  Vice President of Land
Brad Fisher.................................................    $178,500
  Vice President of Operations
</Table>

     Each of the employment agreements also provided for the initial grants of
stock options for Messrs. Johnson and Wojtek and revisions to previously granted
stock options for Mr. Trahan.

     Each of the employment agreements of Mr. Johnson, Mr. Wojtek, Mr. Trahan,
Mr. Greene and Mr. Fisher has an initial three-year term provided that at the
end of the second year of such initial term and on every day thereafter, the
term of each such employment agreement will automatically be extended for one
day, such that the remaining term of the agreement shall never be less than one
year. Under each agreement, both the Company and the employee may terminate the
employee's employment at any time. Upon termination of employment on account of
disability or if employment is terminated by the Company for any reason (except
under certain limited circumstances defined as "for cause" in the agreement), or
if employment is terminated either (x) by the employee subsequent to a change of
control (as defined and including certain terminations prior to a change of
control if caused by a person involved in precipitating a change of control) or
(y) by reason of death during a sixty day period following the elapse of one
year after such a change of control ("window period") or with good reason (as
defined), under the agreement the employee will generally be entitled to (i) an
immediate lump sum cash payment equal to 150% (375% if termination occurs after
a change of control) of his annual base salary that would have been payable for
the remainder of the term of the applicable agreement discounted at 6%, (ii)
continued participation in all the Company's welfare benefit plans and continued
life insurance and medical benefits coverage and (iii) the immediate vesting of
any stock options or restricted stock previously granted to such employee and
outstanding as of the time immediately prior to the date of his termination, or
a cash payment in lieu thereof (the "Cash Election"). Provided that the
Performance Shares vest only if the termination of employment is by the employee
with good reason or during a window period or is by the Company without cause,
then in the event of a Cash Election, the employee, in the case of Mr. Trahan,
will receive in exchange for any or all compensatory awards that are either
denominated in or payable in Common Stock, including options and restricted
stock, an amount in cash equal to the excess of (x) the highest price per share
(as defined below) over (y) the exercise or purchase price, if any, of such
awards. The Term "Highest Price Per Share" generally means the highest price per
share that can be determined to have been paid or agreed to be paid for any
share of Common Stock by certain classes of persons, including (1) a beneficial
owner of 10% or more of the outstanding voting stock of the Company and (2) a
person who has any material involvement in proposing or effectuating a change of
control (as defined). If employment terminates due to death of the employee and
other than in a window period, the Company will pay a sum equal to the amount of
the employee's annual base salary for the remaining term of the agreement,
reduced by the amount payable under any life insurance policies to the extent
that such amounts are attributable to premiums paid by the Company. The salaries
in each of these agreements are subject to periodic review and provide for
increases consistent with increases in base salary generally awarded to other
executives of the Company. Each agreement entitles the employee to participate
in all of the Company's incentive, savings, retirement and welfare benefit plans
in which other executive officers of the Company

                                        18


participate. The agreements each provide for an annual bonus in an amount
comparable to the annual bonus of other Company executives, taking into account
the individual's position and responsibilities.

AUDIT COMMITTEE REPORT

     The Audit Committee's purpose is to assist the Board of Directors in its
oversight of the Company's internal controls and financial statements and the
audit process. The Board of Directors, in its business judgment, has determined
that the members of the Audit Committee, other than possibly Mr. Martin, are
"independent", as required by applicable standards of the Nasdaq Stock Market.
See "Board of Directors and Committees of the Board." The Audit Committee
operates pursuant to a written charter adopted by our Board of Directors; a copy
of the current Audit Committee charter was attached to the proxy statement for
the 2001 Annual Meeting as Appendix A.

     Management is responsible for the preparation, presentation and integrity
of the Company's financial statements, accounting and financial reporting
principles and internal controls and procedures designed to assure compliance
with accounting standards and applicable laws and regulations. The independent
auditors are responsible for performing an independent audit of the consolidated
financial statements in accordance with generally accepted auditing standards.

     In performing its oversight role, the Audit Committee has reviewed and
discussed the audited financial statements with management and the independent
auditors. The Audit Committee has also discussed with the independent auditors
the matters required to be discussed by Statement on Auditing Standards No. 61,
Communication with Audit Committees, as currently in effect. The Audit Committee
has received the written disclosures and the letter from the independent
auditors required by Independence Standards Board Standard No. 1, Independence
Discussions with Audit Committees, as currently in effect.

     Based on the reports and discussions described in this report, and subject
to the limitations on the role and responsibilities of the Audit Committee
referred to below and in the Charter, the Audit Committee recommended to the
Board of Directors that the audited financial statements be included in the
Annual Report on Form 10-K for the fiscal year ended December 31, 2002.

     Members of the Audit Committee rely, without independent verification, on
the information provided to them and on the representations made by management
and the independent auditors. Accordingly, the Audit Committee's oversight does
not provide an independent basis to determine that management has maintained
appropriate accounting and financial reporting principles or appropriate
internal controls and procedures designed to assure compliance with accounting
standards and applicable laws and regulations. Furthermore, the Audit
Committee's considerations and discussions referred to above do not assure that
the audit of the Company's financial statements has been carried out in
accordance with generally accepted auditing standards, that the financial
statements are presented in accordance with generally accepted accounting
principles or that the independent auditors are in fact "independent".

                        PROPOSAL TO AMEND INCENTIVE PLAN
                 TO PROVIDE FOR ADDITIONAL STOCK OPTION GRANTS
               TO THE CHAIRMAN AND MEMBERS OF CERTAIN COMMITTEES
                           OF THE BOARD OF DIRECTORS

     At the time of its initial public offering, the Company adopted the
Incentive Plan. The objectives of the Incentive Plan are to:

     - attract and retain the services of key employees, qualified directors and
       qualified consultants and other independent contractors; and

     - encourage the sense of proprietorship in and stimulate the active
       interest of those persons in the development and financial success of the
       Company by making awards ("Awards") designed to provide participants in
       the Incentive Plan with proprietary interest in the growth and
       performance of the Company.

     The Company currently has reserved 1,850,000 shares of Common Stock for use
in connection with the Incentive Plan. Persons eligible for Awards are (i)
employees holding positions of responsibility with the Company and whose
performance can have a significant effect on the success of the Company, (ii)
Non-employee Directors and (iii) certain non-employee consultants and other
independent contractors. As described in "Certain Transactions" the Company has
agreed in the Shareholders Agreement dated December 15, 1999 to limit the
maximum number of common stock equivalents issuable under the Company's equity
incentive plans to 2.5 million shares and equivalents (including any shares and
equivalents issued or issuable as of December 15, 1999 without the consent of
certain parties to that Agreement).

     As of March 31, 2003, options under the Incentive Plan had been granted to
53 current and former employees and directors of the Company to purchase a total
of approximately 1,490,000 shares of Common Stock at an exercise price per share
not less than fair market value on the date of grant (the initial public
offering price to the public in the case of options awarded in connection with
the initial public offering). As of March 31, 2003, there were 360,000 shares
available for issuance under the Plan.

     The Compensation Committee of the Company's Board of Directors (the
"Committee") administers the Incentive Plan and has broad power to take actions
thereunder, to interpret the Incentive Plan and to adopt rules, regulations and
guidelines for carrying out its purposes. With respect to Awards to employees
and independent contractors, the Committee may, in its discretion, among other
things, extend or accelerate the exercisability of, accelerate the vesting of or
eliminate or make less restrictive any restrictions contained in any Award,
waive any restrictions or other provision of the Incentive Plan or in any Award
or otherwise amend or modify any Award in any manner that is either (i) not
adverse to that participant holding the Award or (ii) consented to by that
participant. The Committee also may delegate to the chief executive officer and
other senior officers of the Company its duties under the Incentive Plan. In
recent times, any action taken with respect to executive officers or directors
of the Company has also been approved by the entire Board.

     The Board of Directors may amend, modify, suspend or terminate the
Incentive Plan for the purpose of addressing any changes in legal requirements
or for any other lawful purpose, except that (i) no amendment or alteration that
would adversely affect the rights of any participant under any Award previously
granted to such participant shall be made without the consent of such
participant and (ii) no amendment or alteration shall be effective prior to its
approval by the shareholders of the Company to the extent such approval is then
required pursuant to Rule 16b-3 in order to preserve the applicability of any
exemption provided by such rule to any Award then outstanding (unless the holder
of such Award consents) or to the extent shareholder approval is otherwise
required by applicable legal requirements. The Board of Directors may make
certain adjustments in the event of any subdivision, split or consolidation of
outstanding shares of Common Stock, any declaration of a stock dividend payable
in shares of Common Stock, any recapitalization or capital reorganization of the
Company, any consolidation or merger of the Company with another corporation or
entity, any adoption by the Company of any plan of exchange affecting the Common
Stock or any distribution to holders of Common Stock of securities or property
(other than normal cash dividends).
                                        21


     Awards to employees and independent contractors may be in the form of (i)
rights to purchase a specified number of shares of Common Stock at a specified
price not less than that of the fair market value on the date of grant
("Options"), (ii) rights to receive a payment, in cash or Common Stock, equal to
the fair market value or other specified value of a number of shares of Common
Stock on the rights exercise date over a specified strike price, (iii) grants of
restricted or unrestricted Common Stock units denominated in Common Stock, (iv)
grants denominated in cash and (v) grants denominated in cash, Common Stock,
units denominated in Common Stock or any other property which are made subject
to the attainment of one or more performance goals ("Performance Awards").
Subject to certain limitations, the Committee has the authority to determine the
other terms, conditions and limitations of Awards under the Incentive Plan. An
Option may be either an incentive stock option ("ISO") that qualifies, or a
non-qualified stock option ("NSO") that does not qualify, with the requirements
of Sections 422 of the Code; provided, that independent contractors cannot be
awarded ISOs. The Committee will determine the employees and independent
contractors to receive Awards and the terms, conditions and limitations
applicable to each such Award, which conditions may, but need not, include
continuous service with the Company, achievement of specific business
objectives, attainment of specified growth rates, increases in specified indices
or other comparable measures of performance. Performance Awards may include more
than one performance goal, and a performance goal may be based on one or more
business criteria applicable to the grantee, the Company as a whole or one or
more of the Company's business units and may include any of the following:
increased revenue, net income, stock price, market share, earnings per share,
return on equity or assets or decrease in costs.

     On the date of his or her first appointment or election to the Board of
Directors, a non-employee director will be granted NSOs to purchase 10,000
shares of Common Stock. In addition, on the first business day following the
date on which each annual meeting of the Company's shareholders is held, each
non-employee director then serving will automatically be granted NSOs to
purchase 2,500 shares of Common Stock. Each NSO granted to non-employee
directors will (i) have a ten-year term, (ii) have an exercise price per share
equal to the fair market value of a Common Stock share on the date of grant and
(iii) become exercisable in cumulative annual increments of one-third of the
total number of shares of Common Stock subject thereto, beginning on the first
anniversary of the date of grant. If a non-employee director resigns from the
Board without the consent of a majority of the other directors, such director's
NSOs may be exercised only to the extent that they were exercisable on the
resignation date.

     On February 18, 2003, the Board of Directors amended the Incentive Plan
into order to make a special grant to Mr. Parker of NSOs to purchase 25,000
shares of Common Stock.

     If the shareholders vote in favor of the proposal set forth herein:

     - the Chairman of the Audit Committee and the Chairman of the Compensation
       Committee will automatically be granted additional NSOs to purchase 3,000
       and 2,000 shares of Common Stock, respectively, on the first business day
       following the date on which each annual meeting of the Company's
       shareholders is held; and

     - the Board of Directors may, in its discretion, grant NSOs to purchase of
       up to 3,000 shares and up to 2,000 shares, respectively, on the date
       specified to non-chairmen members of the Audit and Compensation
       Committees who are deemed by the Committee to be "independent" for
       purposes of the rules of the Nasdaq Stock Market.

     If approved by shareholders, these grants could be made to the chairman or
a member of the Audit Committee or Compensation Committee, respectively,
notwithstanding that the same person may also receive grants as a chairman or
member of the Compensation Committee or Audit Committee, respectively.

NEW PLAN BENEFITS

     The allocation of some of the proposed new benefits under the Incentive
Plan is not currently determinable as such allocation is dependent upon future
decisions to be made by the Compensation Committee or the Board of Directors in
their sole discretion, subject to applicable provisions of the Incentive

                                        22


Plan. However, Mr. Parker, the current chairman of both the Audit Committee and
the Compensation Committee, will annually receive a grant of NSOs to purchase
5,000 shares of Common Stock (in addition to his annual grant as an outside
director) if this amendment to the Incentive Plan is approved by shareholders.
No executive officers or other employees are eligible for these grants.

FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of the general rules of present federal income
tax law relating to the tax treatment of stock awards, ISOs and NSOs issued
under the Incentive Plan. The discussion is general in nature and does not take
into account a number of considerations which may apply in light of the
particular circumstances of a participant under the Incentive Plan.

STOCK AWARDS AND RELATED TAX PAYMENTS

     Under the Code, federal income tax consequences with respect to a stock
award depend on the facts and circumstances of each stock award and, in
particular, the nature of the restrictions imposed with respect to the shares
which are the subject of the stock award. In general, if shares which are the
subject of the stock award are actually issued to a participant, but are subject
to a "substantial risk of forfeiture" (for example, if rights to ownership of
the shares are conditioned upon the future performance of substantial services
by the participant), a taxable event generally occurs only when the risk of
forfeiture lapses. At such time as the substantial risk of forfeiture lapses,
the participant will realize ordinary income to the extent of the excess of the
fair market value of the shares on the date the risk of forfeiture lapses over
the participant's cost for such shares (if any), and the same amount is then
deductible by the Company as compensation expense. If the restrictions with
respect to the shares that are the subject of such stock award, by their nature,
do not subject the key employee to a "substantial risk of forfeiture" of the
shares, then the participant will realize ordinary income with respect to the
shares to the extent of the excess at the time of the grant of the fair market
value of the shares over the participant's cost; and the same amount is then
deductible by the Company. If no shares are actually issued to the participant
at the time the stock award is granted, the participant will generally realize
ordinary income at the time the participant receives shares free of any
substantial risk of forfeiture, and the amount of such income will be equal to
the fair market value of the shares at such time over the participant's cost, if
any; and the same amount is then deductible by the Company. The Company's
deductions for compensation paid under the Incentive Plan are in all cases
subject to certain applicable tax law limitations.

OPTIONS

     Some of the options issuable under the Incentive Plan may constitute ISOs
within the meaning of Section 422 of the Code, while other options granted under
the Incentive Plan may be NSOs. Grants to non-employee directors are NSOs. The
Code provides for tax treatment of stock options qualifying as ISOs that may be
more favorable to participants than the tax treatment accorded NSOs. Generally,
upon the exercise of an ISO, the optionee will recognize no income for federal
income tax purposes. The difference between the exercise price of the ISO and
the fair market value of the stock at the time of exercise is an addition to
income in determining alternative minimum taxable income and such amount may be
sufficient in amount to subject the optionee to the alternative minimum tax. On
the sale of shares acquired by exercise of an ISO (assuming that the sale does
not occur within two years of the date of grant of the option or within one year
from the date of exercise), any gain will be taxed to the optionee as long-term
capital gain. In contrast, upon the exercise of an NSO, the optionee recognizes
taxable income (subject to withholding) in an amount equal to the difference
between the then-fair market value of the shares on the date of exercise and the
exercise price. Upon any sale of such shares by the optionee, any difference
between the sale price and the fair market value of the shares on the date of
exercise of the NSO will be treated generally as capital gain or loss. No
deduction is available to the Company upon the grant or exercise of an ISO
(although a deduction may be available if the participant disposes of the shares
so purchased before the applicable holding periods expire), whereas, upon
exercise of an NSO, the Company is entitled to a deduction in an amount equal to
the income

                                        23


recognized by the participant. Except with respect to death or disability, an
optionee has three months after termination of employment in which to exercise
an ISO and retain favorable tax treatment at exercise.

OTHER

     In general, a federal income tax deduction is allowed to the Company in an
amount equal to the ordinary income recognized by a participant with respect to
awards under the Incentive Plan, provided that such amount constitutes an
ordinary and necessary business expense of the Company, that such amount is
reasonable and that the Company satisfies any withholding obligation with
respect to such income.

     A copy of the Amended and Restated Incentive Plan, the First and Second
Amendments to the Incentive Plan, and the proposed Third Amendment to the
Incentive Plan is attached as Appendix A.

BOARD RECOMMENDATION

     The Board believes that the amendment of the Incentive Plan is in the best
interest of the Company and its shareholders. The Board recognizes that
additional time and attention and new burdens are now required of directors as a
result of the Sarbanes-Oxley Act of 2002, as well as other regulations and
Nasdaq Stock Market requirements. The Board believes the additional grants of
NSOs that are either required or allowed by the amendment will help to
compensate for the additional time and attention and new burdens and help the
Company in attracting and retaining qualified board members. THE BOARD THEREFORE
RECOMMENDS A VOTE FOR APPROVAL OF THE AMENDMENT, AND IT IS INTENDED THAT THE
PROXIES NOT MARKED TO THE CONTRARY WILL BE SO VOTED. Since the amendment will
increase the number of shares available for issuance under the Incentive Plan to
certain directors of the Company, certain directors of the Company have an
interest in and may benefit from the adoption of the amendment. Approval of the
amendment to the Incentive Plan will require the affirmative vote of a majority
of the shares of Common Stock cast with respect to the consideration of the
amendment. Accordingly, abstentions and broker non-votes will not be included in
the tabulation of votes cast on this matter.

                                   PROPOSAL 3

                 APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS

     The Board of Directors has appointed, and recommends the approval of the
appointment of, Ernst & Young LLP, as independent public accountants for the
fiscal year ending December 31, 2003. Ernst & Young LLP served as independent
public accountants for the fiscal year ended December 31, 2002. Representatives
of Ernst & Young LLP are expected to be present at the Annual Meeting and will
be given the opportunity to make a statement, if they desire to do so, and to
respond to appropriate questions.

     Unless shareholders specify otherwise in the proxy, proxies solicited by
the Board of Directors will be voted by the persons named in the proxy at the
Annual Meeting to ratify the selection of Ernst & Young LLP as the Company's
auditors for 2003. The affirmative vote of a majority of the votes cast at the
Annual Meeting will be required for ratification.

PRINCIPAL AUDITOR FEES

     Ernst & Young LLP billed the Company as set forth in the table below for
professional services rendered for the audit of the Company's annual financial
statements for 2002 and the reviews of the Company's quarterly financial
statements included in the Company's Quarterly Reports on Form 10-Q for 2002. No
fees were incurred for services rendered in 2002 related to financial
information systems design and implementation or any other services.

     THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE
RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP.

INFORMATION REGARDING CHANGE OF INDEPENDENT PUBLIC ACCOUNTANTS

     The Audit Committee annually considers and recommends to the Board of
Directors the selection of the Company's independent public accountants. As
recommended by the Audit Committee, the Board of Directors on April 11, 2002
decided to no longer engage Arthur Andersen LLP as the Company's independent
public accountants and engaged Ernst & Young LLP to serve as the Company's
independent public accountants for the fiscal year ended December 31, 2002.

     Arthur Andersen's reports on the Company's consolidated financial
statements for the year ended December 31, 2001 did not contain an adverse
opinion or disclaimer of opinion, nor were they qualified or modified as to
uncertainty, audit scope or accounting principles.

     During the years ended December 31, 2000 and 2001 and through April 11,
2002 (the date of Arthur Andersen's dismissal), there were no disagreements with
Arthur Andersen on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure which, if not resolved to
Arthur Andersen's satisfaction, would have caused them to make reference to the
subject matter in connection with their report on the Company's consolidated
financial statements for such years; and there were no reportable events, as
listed in Item 304(a)(1)(v) of SEC Regulation S-K.

     During the year ended December 31, 2001 and through April 11, 2002, the
Company did not consult Ernst & Young LLP with respect to the application of
accounting principles to a specific transaction, either completed or proposed,
or the type of audit opinion that might be rendered on the Company's
consolidated

                                        25


financial statements, or any other matters or reportable events listed in Items
304(a)(2)(i) and (ii) of SEC Regulation S-K.

INDEPENDENCE OF AUDITORS

     As indicated in the "Principal Auditor Fees" table above, Ernst & Young LLP
did not render any non-audit services to the Company in 2002. Accordingly, with
respect to 2002, the Audit Committee was not required to consider whether the
provision of any services for financial information systems design and
implementation or other non-audit services was compatible with maintaining Ernst
& Young LLP's independence.

OTHER BUSINESS

     As of the date of this proxy statement, the Board of Directors is not
informed of any other matters, other than those above, that may be brought
before the meeting. The persons named in the enclosed form of proxy or their
substitutes will vote with respect to any such matters in accordance with their
best judgment.

SHAREHOLDER PROPOSALS FOR NEXT ANNUAL MEETING

     Rule 14a-8 under the Securities Exchange Act of 1934, as amended, addresses
when a company must include a shareholder's proposal in its proxy statement and
identify the proposal in its form of proxy when the company holds an annual or
special meeting of shareholders. Under Rule 14a-8, proposals that shareholders
intend to have included in the Company's proxy statement and form of proxy for
the 2004 Annual Meeting of Shareholders must be received by the Company no later
than December 24, 2003. However, if the date of the 2004 Annual Meeting of
Shareholders changes by more than 30 days from the date of the 2004 Annual
Meeting of Shareholders, the deadline is a reasonable time before the Company
begins to print and mail its proxy materials, which deadline will be set forth
in a Quarterly Report on Form 10-Q or will otherwise be communicated to
shareholders. Shareholder proposals must also be otherwise eligible for
inclusion.

     If a shareholder desires to bring a matter before an annual or special
meeting and the proposal is submitted outside the process of Rule 14a-8, the
shareholder must follow the procedures set forth in the Company's Bylaws. The
Company's Bylaws provide generally that shareholders who wish to nominate
directors or to bring business before a shareholders' meeting must notify the
Company and provide certain pertinent information at least 80 days before the
meeting date (or within ten days after public announcement pursuant to the
Bylaws of the meeting date, if the meeting date has not been publicly announced
more than 90 days in advance). If the date of the 2004 Annual Meeting of
Shareholders is the same as the date of the 2003 Annual Meeting of Shareholders,
shareholders who wish to nominate directors or to bring business before the 2004
Annual Meeting of Shareholders must notify the Company no later than March 4,
2004.

virtue of the provisions of Rule 16b-3, (i) the Committee shall consist of at
least two members of the Board who meet the requirements of the definition of
"non-employee director" set forth in Rule 16b-3(b)(3)(i) promulgated under the
Exchange Act or (ii) Awards may be granted by, and the Plan may be administered

Employee Awards or Independent Contractor Awards, the Committee shall have full
and exclusive power and authority to administer this Plan and to take all
actions that are specifically contemplated hereby or are necessary or
appropriate in connection with the administration hereof. Insofar as this Plan
relates to Employee Awards or Independent Contractor Awards, the Committee shall
also have full and exclusive power to interpret this Plan and to adopt such
rules, regulations and guidelines for carrying out this Plan as it may deem
necessary or proper, all of which powers shall be exercised in the best
interests of the Company and in keeping with the objectives of this Plan. The
Committee may, in its discretion, provide for the extension of the
exercisability of an Employee Award or Independent Contractor Award, accelerate
the vesting or exercisability of an Employee Award or Independent Contractor
Award, eliminate or make less restrictive any restrictions contained in an
Employee Award or Independent Contractor Award, waive any restriction or other
provision of this Plan (insofar as such provision relates to Employee Awards or
to Independent Contractor Awards) or an Employee Award or Independent Contractor
Award or otherwise amend or modify an Employee Award or Independent Contractor
Award in any manner that is either (i) not adverse to the Participant to whom
such Employee Award or Independent Contractor Award was granted or (ii)
consented to by such Participant. The Committee may make an award to an
individual who it expects to become an Employee of the Company or any of its
Subsidiaries within the next six months, with such award being subject to the
individual's actually becoming an Employee within such time period, and subject
to such other terms and conditions as may be established by the Committee. The
Committee may correct any defect or supply any omission or reconcile any
inconsistency in this Plan or in any Employee Award or Independent Contractor
Award in the manner and to the extent the Committee deems necessary or desirable
to further the Plan purposes. Any decision of the Committee in the
interpretation and administration of this Plan shall lie within its sole and
absolute discretion and shall be final, conclusive and binding on all parties
concerned.

     (c) No member of the Committee or officer of the Company to whom the
Committee has delegated authority in accordance with the provisions of paragraph

connection with the performance of any duties under this Plan, except for his or
her own willful misconduct or as expressly provided by statute.

     8.  Employee and Independent Contractor Awards.

     (a) The Committee shall determine the type or types of Employee Awards to
be made under this Plan and shall designate from time to time the Employees who
are to be the recipients of such Awards. Each Employee Award may be embodied in
an Employee Award Agreement, which shall contain such terms, conditions and
limitations as shall be determined by the Committee in its sole discretion and
shall be signed by the Participant to whom the Employee Award is made and by an
Authorized Officer for and on behalf of the Company. Employee Awards may consist
of those listed in this paragraph 8(a) hereof and may be granted singly, in
combination or in tandem. Employee Awards may also be made in combination or in
tandem with, in replacement of, or as alternatives to, grants or rights under
this Plan or any other employee plan of the Company or any of its Subsidiaries,
including the plan of any acquired entity. An Employee Award may provide for the
grant or issuance of additional, replacement or alternative Employee Awards upon
the occurrence of specified events, including the exercise of the original
Employee Award granted to a Participant. All or part of an Employee Award may be
subject to conditions established by the Committee, which may include, but are
not limited to, continuous service with the Company and its Subsidiaries,
achievement of specific business objectives, increases in specified indices,
attainment of specified growth rates and other comparable measurements of
performance. Upon the termination of employment by a Participant who is an
Employee, any unexercised, deferred, unvested or unpaid Employee Awards shall be
treated as set forth in the applicable Employee Award Agreement.

          (i) Stock Option.  An Employee Award may be in the form of an Option.
     An Option awarded pursuant to this Plan may consist of an Incentive Option
     or a Nonqualified Option. The price at which shares of Common Stock may be
     purchased upon the exercise of an Incentive Option shall be not less than
     the Fair Market Value of the Common Stock on the date of grant. The price
     at which shares of Common Stock may be purchased upon the exercise of a
     Nonqualified Option shall be not less than the Fair Market Value of the
     Common Stock on the date of grant. Subject to the foregoing provisions, the
     terms, conditions and limitations applicable to any Options awarded
     pursuant to this Plan, including the term of any Options and the date or
     dates upon which they become exercisable, shall be determined by the
     Committee.

          (ii) Stock Appreciation Right.  An Employee Award may be in the form
     of an SAR. The terms, conditions and limitations applicable to any SARs
     awarded pursuant to this Plan, including the term of any SARs and the date
     or dates upon which they become exercisable, shall be determined by the
     Committee.

          (iii) Stock Award.  An Employee Award may be in the form of a Stock

     Award. The terms, conditions and limitations applicable to any Cash Awards
     granted pursuant to this Plan shall be determined by the Committee.

          (v) Performance Award.  Without limiting the type or number of
     Employee Awards that may be made under the other provisions of this Plan,
     an Employee Award may be in the form of a Performance Award. A Performance
     Award shall be paid, vested or otherwise deliverable solely on account of
     the attainment of one or more pre-established, objective Performance Goals
     established by the Committee prior to the earlier to occur of (x) 90 days
     after the commencement of the period of service to which the Performance
     Goal relates and (y) the lapse of 25% of the period of service (as
     scheduled in good faith at the time the goal is established), and in any
     event while the outcome is substantially uncertain. A Performance Goal is
     objective if a third party having knowledge of the relevant facts could
     determine whether the goal is met. Such a Performance Goal may be based on
     one or more business criteria that apply to the individual, one or more
     business units of the Company, or the Company as a whole, and may include
     one or more of the following: increased revenue, net income, stock price,
     market share, earnings per share, return on equity, return on assets or
     decrease in costs. Unless otherwise stated, such a Performance Goal need
     not be based upon an increase or positive result under a particular
     business
                                        31


     criterion and could include, for example, maintaining the status quo or
     limiting economic losses (measured, in each case, by reference to specific
     business criteria). In interpreting Plan provisions applicable to
     Performance Goals and Performance Awards, it is the intent of the Plan to
     conform with the standards of Section 162(m) of the Code and Treasury
     Regulation sec. 1.162-27(e)(2)(i), and the Committee in establishing such
     goals and interpreting the Plan shall be guided by such provisions. Prior
     to the payment of any compensation based on the achievement of Performance
     Goals, the Committee must certify in writing that applicable Performance
     Goals and any of the material terms thereof were, in fact, satisfied.
     Subject to the foregoing provisions, the terms, conditions and limitations
     applicable to any Performance Awards made pursuant to this Plan shall be
     determined by the Committee.

     (b) Notwithstanding anything to the contrary contained in this Plan, the
following limitations shall apply to any Employee Awards made hereunder:

          (i) no Participant may be granted, during any one-year period,
     Employee Awards consisting of Options or SARs that are exercisable for more
     than 250,000 shares of Common Stock;

          (ii) no Participant may be granted, during any one-year period, Stock
     Awards covering or relating to more than 50,000 shares of Common Stock (the

     the "Stock Based Awards Limitations"); and

          (iii) no Participant may be granted Employee Awards consisting of cash
     or in any other form permitted under this Plan (other than Employee Awards
     consisting of Options or SARs or otherwise consisting of shares of Common
     Stock or units denominated in such shares) in respect of any one-year
     period having a value determined on the date of grant in excess of
     $500,000.

     (c) The Committee shall have the sole responsibility and authority to
determine the type or types of Independent Contractor Awards to be made under

than Incentive Options.

     9.  Director Awards.  Each Nonemployee Director of the Company shall be
granted Director Awards in accordance with this paragraph 9 and subject to the
applicable terms, conditions and limitations set forth in this Plan and the
applicable Director Award Agreement. Notwithstanding anything to the contrary
contained herein, Director Awards shall not be made in any year in which a
sufficient number of shares of Common Stock are not available to make such
Awards under this Plan.

     (a) Initial Director Options.  On the IPO Closing Date, each Nonemployee
Director shall be automatically awarded a Director Option on 10,000 shares of

granted a Director Option that provides for the purchase of 2,500 shares of
Common Stock.

     (c) Terms.  Each Director Option shall have a term of ten years from the
date of grant, notwithstanding any earlier termination of the status of the
holder as a Nonemployee Director. The purchase price of each share of Common
Stock subject to a Director Option shall be equal to the Fair Market Value of
the Common Stock on the date of grant. All Director Options shall vest and
become exercisable in increments of one-third of the total number of shares of
Common Stock that are subject thereto (rounded up to the nearest whole number)
on the first and second anniversaries of the date of grant and of all remaining
shares of Common Stock that are subject thereto on the third anniversary of the
date of grant. All unvested Director Options shall be forfeited if the
Nonemployee Director resigns as a Director without the consent of a majority of
the other Directors.

                                        32


     (d) Agreements.  Any Award of Director Options shall be embodied in a
Director Award Agreement, which shall contain the terms, conditions and
limitations set forth above and shall be signed by the Participant to whom the
Director Options are granted and by an Authorized Officer for and on behalf of
the Company.

     10.  Payment of Awards.

     (a) General.  Payment of Employee Awards or Independent Contractor Awards
may be made in the form of cash or Common Stock, or a combination thereof, and
may include such restrictions as the Committee shall determine, including, in
the case of Common Stock, restrictions on transfer and forfeiture provisions. If
payment of an Employee Award or Independent Contractor Award is made in the form
of Restricted Stock, the applicable Award Agreement relating to such shares
shall specify whether they are to be issued at the beginning or end of the
Restriction Period. In the event that shares of Restricted Stock are to be
issued at the beginning of the Restriction Period, the certificates evidencing
such shares (to the extent that such shares are so evidenced) shall contain
appropriate legends and restrictions that describe the terms and conditions of
the restrictions applicable thereto. In the event that shares of Restricted
Stock are to be issued at the end of the Restricted Period, the right to receive
such shares shall be evidenced by book entry registration or in such other
manner as the Committee may determine.

     (b) Deferral.  With the approval of the Committee, amounts payable in
respect of Employee Awards or Independent Contractor Awards may be deferred and
paid either in the form of installments or as a lump-sum payment. The Committee
may permit selected Participants to elect to defer payments of some or all types
of Employee Awards or Independent Contractor Awards in accordance with
procedures established by the Committee. Any deferred payment of an Employee
Award or Independent Contractor Award, whether elected by the Participant or
specified by the Award Agreement or by the Committee, may be forfeited if and to
the extent that the Award Agreement so provides.

     (c) Dividends and Interest.  Rights to dividends or Dividend Equivalents
may be extended to and made part of any Employee Award or Independent Contractor
Award consisting of shares of Common Stock or units denominated in shares of
Common Stock, subject to such terms, conditions and restrictions as the
Committee may establish. The Committee may also establish rules and procedures
for the crediting of interest on deferred cash payments and Dividend Equivalents
for Employee Awards or Independent Contractor Awards consisting of shares of
Common Stock or units denominated in shares of Common Stock.

     (d) Substitution of Awards.  At the discretion of the Committee, a
Participant who is an Employee or Independent Contractor may be offered an
election to substitute an Employee Award or Independent Contractor Award for
another Employee Award or Independent Contractor Award or Employee Awards or
Independent Contractor Awards of the same or different type.

     11.  Stock Option Exercise.  The price at which shares of Common Stock may
be purchased under an Option shall be paid in full at the time of exercise in
cash or, if elected by the optionee, the optionee may purchase such shares by
means of tendering Common Stock or surrendering another Award, including
Restricted Stock or Director Restricted Stock, valued at Fair Market Value on
the date of exercise, or any combination thereof. The Committee shall determine
acceptable methods for Participants who are Employees or Independent Contractors
to tender Common Stock or other Employee Awards or Independent Contractor
Awards; provided that any Common Stock that is or was the subject of an Employee
Award or Independent Contractor Award may be so tendered only if it has been
held by the Participant for six months. The Committee may provide for procedures
to permit the exercise or purchase of such Awards by use of the proceeds to be
received from the sale of Common Stock issuable pursuant to an Employee Award or
Independent Contractor Award. Unless otherwise provided in the applicable Award
Agreement, in the event shares of Restricted Stock are tendered as consideration
for the exercise of an Option, a number of the shares issued upon the exercise
of the Option, equal to the number of shares of Restricted Stock or Director
Restricted Stock used as consideration therefor, shall be subject to the same
restrictions as the Restricted Stock or Director Restricted Stock so submitted
as well as any additional restrictions that may be imposed by the Committee.

                                        33


     12.  Taxes.  The Company shall have the right to deduct applicable taxes
from any Employee Award payment and withhold, at the time of delivery or vesting
of cash or shares of Common Stock under this Plan, an appropriate amount of cash
or number of shares of Common Stock or a combination thereof for payment of
taxes required by law or to take such other action as may be necessary in the
opinion of the Company to satisfy all obligations for withholding of such taxes.
The Committee may also permit withholding to be satisfied by the transfer to the
Company of shares of Common Stock theretofore owned by the holder of the
Employee Award with respect to which withholding is required. If shares of
Common Stock are used to satisfy tax withholding, such shares shall be valued
based on the Fair Market Value when the tax withholding is required to be made.
The Committee may provide for loans, on either a short term or demand basis,
from the Company to a Participant who is an Employee or Independent Contractor
to permit the payment of taxes required by law.

     13.  Amendment, Modification, Suspension or Termination.  The Board may
amend, modify, suspend or terminate this Plan for the purpose of meeting or
addressing any changes in legal requirements or for any other purpose permitted
by law, except that (i) no amendment or alteration that would adversely affect
the rights of any Participant under any Award previously granted to such
Participant shall be made without the consent of such Participant and (ii) no
amendment or alteration shall be effective prior to its approval by the
stockholders of the Company to the extent such approval is then required
pursuant to Rule 16b-3 in order to preserve the applicability of any exemption
provided by such rule to any Award then outstanding (unless the holder of such
Award consents) or to the extent stockholder approval is otherwise required by
applicable legal requirements.

     14.  Assignability.  Unless otherwise determined by the Committee and
provided in the Award Agreement, no Award or any other benefit under this Plan
constituting a derivative security within the meaning of Rule 16a-1(c) under the
Exchange Act shall be assignable or otherwise transferable except by will or the
laws of descent and distribution or pursuant to a qualified domestic relations
order as defined by the Code or Title I of the Employee Retirement Income
Security Act, or the rules thereunder. The Committee may prescribe and include
in applicable Award Agreements other restrictions on transfer. Any attempted
assignment of an Award or any other benefit under this Plan in violation of this
paragraph 14 shall be null and void.

     15.  Adjustments.

     (a) The existence of outstanding Awards shall not affect in any manner the
right or power of the Company or its stockholders to make or authorize any or
all adjustments, recapitalizations, reorganizations or other changes in the
capital stock of the Company or its business or any merger or consolidation of
the Company, or any issue of bonds, debentures, preferred or prior preference
stock (whether or not such issue is prior to, on a parity with or junior to the
Common Stock) or the dissolution or liquidation of the Company, or any sale or
transfer of all or any part of its assets or business, or any other corporate
act or proceeding of any kind, whether or not of a character similar to that of
the acts or proceedings enumerated above.

merger of the Company with another corporation or entity, the adoption by the
Company of any plan of exchange affecting the Common Stock or any distribution
to holders of Common Stock of securities or property (other than normal cash
dividends or dividends payable in Common Stock), the Board shall make
appropriate adjustments to (i) the number of shares of Common Stock covered by
Awards in the form of Common Stock or units denominated in Common Stock, (ii)
the exercise or other price in respect of such Awards, (iii) the

                                        34


appropriate Fair Market Value and other price determinations for such Awards,
(iv) the number of shares of Common Stock covered by Director Options
automatically granted pursuant to paragraph 9 hereof and (v) the Stock Based
Awards Limitations to give effect to such transaction shall each be
proportionately adjusted by the Board to reflect such transaction; provided that
such adjustments shall only be such as are necessary to maintain the
proportionate interest of the holders of the Awards and preserve, without
exceeding, the value of such Awards. In the event of a corporate merger,
consolidation, acquisition of property or stock, separation, reorganization or
liquidation, the Board shall be authorized to issue or assume Awards by means of
substitution of new Awards, as appropriate, for previously issued Awards or to
assume previously issued Awards as part of such adjustment.

     (c) In the event of a corporate merger, consolidation, acquisition of
property or stock, separation, reorganization or liquidation, the Board may make
such adjustments to outstanding Awards or other provisions for the disposition
of outstanding Awards as it deems equitable, and shall be authorized, in its
discretion, (i) to provide for the substitution of a new Award or other
arrangement (which, if applicable, may be exercisable for such property or stock
as the Board determines) for an outstanding Award or the assumption of an
outstanding Award, regardless of whether in a transaction to which Section
424(a) of the Code applies, (ii) to provide, prior to the transaction, for the
acceleration of the vesting and exercisability of, or lapse of restrictions with
respect to, the outstanding Award and, if the transaction is a cash merger, to
provide for the termination of any portion of the Award that remains unexercised
at the time of such transaction or (iii) to provide for the acceleration of the
vesting and exercisability of an outstanding Award and the cancellation thereof
in exchange for such payment as shall be mutually agreeable to the Participant
and the Board.

     16.  Restrictions.  No Common Stock or other form of payment shall be
issued with respect to any Award unless the Company shall be satisfied based on
the advice of its counsel that such issuance will be in compliance with
applicable federal and state securities laws. It is the intent of the Company
that grants of Awards under this Plan comply with Rule 16b-3 with respect to
persons subject to Section 16 of the Exchange Act unless otherwise provided
herein or in an Award Agreement, that any ambiguities or inconsistencies in the
construction of such an Award or this Plan be interpreted to give effect to such
intention. Certificates evidencing shares of Common Stock delivered under this
Plan (to the extent that such shares are so evidenced) may be subject to such
stop transfer orders and other restrictions as the Committee may deem advisable
under the rules, regulations and other requirements of the Securities and
Exchange Commission, any securities exchange or transaction reporting system
upon which the Common Stock is then listed or to which it is admitted for
quotation and any applicable federal or state securities law. The Committee may
cause a legend or legends to be placed upon such certificates (if any) to make
appropriate reference to such restrictions.

     17.  Unfunded Plan.  Insofar as it provides for Awards of cash, Common
Stock or rights thereto, this Plan shall be unfunded. Although bookkeeping
accounts may be established with respect to Participants who are entitled to
cash, Common Stock or rights thereto under this Plan, any such accounts shall be
used merely as a bookkeeping convenience. The Company shall not be required to
segregate any assets that may at any time be represented by cash, Common Stock
or rights thereto, nor shall this Plan be construed as providing for such
segregation, nor shall the Company, the Board or the Committee be deemed to be a
trustee of any cash, Common Stock or rights thereto to be granted under this
Plan. Any liability or obligation of the Company to any Participant with respect
to an Award of cash, Common Stock or rights thereto under this Plan shall be
based solely upon any contractual obligations that may be created by this Plan
and any Award Agreement, and no such liability or obligation of the Company
shall be deemed to be secured by any pledge or other encumbrance on any property
of the Company. Neither the Company nor the Board nor the Committee shall be
required to give any security or bond for the performance of any obligation that
may be created by this Plan.

     18.  Governing Law.  This Plan and all determinations made and actions
taken pursuant hereto, to the extent not otherwise governed by mandatory
provisions of the Code or the securities laws of the United States, shall be
governed by and construed in accordance with the laws of the State of Texas.

                                        35


     19.  Effectiveness.  The Plan as hereby amended and restated shall be
effective as of February 17, 2000, except for the change to the definition of
"Independent Contractor" and to the number of authorized shares in Section 5,
which shall become effective upon shareholder approval at the 2000 Annual
Meeting of Shareholders.
