                          MATTERS TO COME BEFORE THE MEETING

PROPOSAL 1:  ELECTION OF DIRECTORS

     At the meeting two directors are to be elected, constituting all of the 
Class I directors.  The Company's Restated Certificate of Incorporation 
provides for the classification of the Board of Directors into three classes 
of directors (Class I, Class II and Class III), with the term of each class 
expiring at successive annual stockholders' meetings.  At and after this 1997 
Annual Meeting of Stockholders, all nominees will be elected for three-year 
terms. Each director will serve until the annual meeting of stockholders at 
which his term expires, or until his respective successor is duly elected and 
qualified or his earlier resignation or removal.  The terms of office of 
Herbert J. Conrad and Louis M. Sherwood, M.D. expire at the meeting, and they 
are both proposed as nominees for terms expiring at the 2000 Annual Meeting 
of Stockholders.  It is the intention of the persons named in the proxies for 
the holders of the Common Stock to vote the proxies for the election of the 
nominees named below, unless otherwise specified in any particular proxy.  
The management of the Company does not contemplate that any of the nominees 
will become unavailable for any reason, but if that should occur before the 
Meeting, proxies will be voted for another nominee, or other nominees, to be 
selected by the Board of Directors.  Any vacancies that may occur during the 
year may be filled by an individual appointed by the Board of Directors to 
serve for the remainder of the term of such director position.  Two Class II 
director positions currently are vacant as a result of director resignations 
earlier in 1997.  The Board of Directors is actively reviewing candidates, 
and, in the event that qualified individuals are identified, the Board of 
Directors plans to appoint directors to these vacant positions, the terms of 
which will expire at the 1998 Annual Meeting of Stockholders.  In accordance 
with the Company's by-laws and Delaware law, a stockholder entitled to vote 
for the election of directors may withhold authority to vote for certain 
nominees for director or may withhold authority to vote for all nominees for 
director.  Each director nominee receiving a plurality of the votes cast in 
person or by proxy at the meeting will be elected director. Abstentions and 
broker non-votes will not be treated as a vote for or against any particular 
director nominee, and will not affect the outcome of the election.

     The following table sets forth certain information with respect to the 
persons who have been nominated to serve three-year terms as director and for 
the Company's other directors:

                                                                        DIRECTOR

PROPOSAL 2:  APPROVAL OF THE AMENDED AND RESTATED STOCK OPTION PLAN

GENERAL

     At the meeting, the stockholders of the Company will be asked to vote 
upon a proposal to approve the Amended and Restated Stock Option Plan.  
Approval of the Amended and Restated Stock Option Plan requires the 
affirmative vote of the holders of a majority of the votes of the shares of 
Common Stock that are outstanding as of the Record Date. The text of the 
proposed Amended and Restated Stock Option Plan is set forth in full in ANNEX 
A to this proxy statement.  The Amended and Restated Stock Option Plan amends 
the UroCor, Inc. Amended and Restated 1992 Stock Option Plan (the "1992 Stock 
Option Plan") to (i) increase the aggregate number of shares of Common Stock 
for which options may be granted under the plan from 1,400,000 to 1,700,000 
and (ii) amend certain provisions of the plan to bring the plan into 
compliance with recently amended federal securities and tax laws.

REASONS FOR THE AMENDED AND RESTATED STOCK OPTION PLAN

     The Board of Directors believes that it is in the best interest of the 
Company to encourage ownership of the Company's stock by its employees, 
directors and consultants.  Providing an opportunity to hold an equity 
interest in the Company assists the Company in attracting and retaining key 
management and consulting personnel, which is critical to the Company's 
long-term success. The number of shares of Common Stock available under the 
1992 Stock Option Plan will be depleted by December 1997, and the Board of 
Directors of the Company has determined that, to continue to provide 
performance-based incentive to the Company's management and key employees, it 
is in the best interest of the Company to increase the number of shares of 
Common Stock available for grant of options under the 1992 Stock Option Plan.

     To provide additional shares of Common Stock for which options may be 
granted under the 1992 Stock Option Plan and to amend certain provisions of 
the plan to bring the plan into compliance with recently amended federal 
securities and tax laws, the Board of Directors has approved the Amended and 
Restated Stock Option Plan and has directed that the same be presented to the 
stockholders for their approval.

CERTAIN CONSIDERATIONS

     Stockholders should note that certain disadvantages may result from 
approval of the Amended and Restated Stock Option Plan, including a reduction 
in their interest of the Company with respect to earnings per share, voting, 
liquidation value and book and market value per share if options to acquire 
shares of Common Stock are granted and subsequently exercised.

                                       -6-

<PAGE>

     THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" APPROVAL OF THE AMENDED 
AND RESTATED STOCK OPTION PLAN.  Approval of the Amended and Restated Stock 
Option Plan requires the affirmative vote of the holders of a majority of the 
votes of the shares of Common Stock that are outstanding as of the Record 
Date.  If not otherwise provided, proxies will be voted "FOR" approval of the 
Amended and Restated Stock Option Plan.  Abstentions and broker non-votes 
will be counted as shares entitled to vote on the proposal, but will not be 
treated as either a vote for or against the proposal.  Therefore, an 
abstention or broker non-vote will have the same effect as a vote against the 
proposal.

PROPOSAL 3:  APPROVAL OF THE DIRECTOR STOCK OPTION PLAN

GENERAL

     At the meeting, the stockholders of the Company will be asked to vote 
upon a proposal to approve the Director Stock Option Plan .  Approval of the 
Director Stock Option Plan requires the affirmative vote of the holders of a 
majority of the shares of Common Stock that are outstanding as of the Record 
Date and entitled to vote thereon.  The text of the proposed Director Stock 
Option Plan is set forth in full in ANNEX B to this proxy statement.  The 
Director Stock Option Plan will (i) provide for the grant of options to 
purchase 10,000 shares of Common Stock to each existing non-employee director 
who has served since January 1, 1989, (ii) provide for the grant of options 
to purchase 7,500 shares of Common Stock to each existing non-employee 
director who has served only since January 1, 1994, (iii) provide for the 
grant of options to purchase 5,000 shares of Common Stock to each existing 
non-employee director who has served only since January 1, 1995, (iv) provide 
for the grant of options to purchase 10,000 shares of Common Stock to any new 
non-employee director on the date of his or her election and (v) provide for 
the grant of options annually to purchase 5,000 shares of Common Stock to 
each non-employee director on July 1 of each year, beginning July 1, 1998.

REASONS FOR THE DIRECTOR STOCK OPTION PLAN

     The Board of Directors believes that it is in the best interest of the 
Company to attract and retain the services of experienced and knowledgeable 
non-employee directors of the Company and to provide an incentive for such 
directors to increase their proprietary interests in the Company's long-term 
success and progress.  In furtherance thereof, the Board of Directors has 
adopted the Director Stock Option Plan and has directed that the same be 
presented to the stockholders for their approval.

CERTAIN CONSIDERATIONS

     Stockholders should note that certain disadvantages may result from the 
adoption of the Director Stock Option Plan, including a reduction in their 
interest of the Company with respect to earnings per share, voting, 
liquidation value and book and market value per share if options to acquire 
shares of Common Stock are granted and subsequently exercised.

     THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" APPROVAL OF THE DIRECTOR 
STOCK OPTION PLAN.  Approval of the Director Stock Option Plan requires the 
affirmative vote of the holders of a majority of the shares of Common Stock 
that are outstanding as of the Record Date.  If not otherwise provided, 
proxies will be voted "FOR" approval of the Director Stock Option Plan.  
Abstentions and broker non-votes will be counted as shares entitled to vote 
on the proposal, but will not be treated as either a vote for or against the

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Compensation Committee of The Board of Directors (the "Committee"), 
which is composed of non-employee Directors and performs the duties described 
on page 6 of this Proxy Statement, has furnished the following report on 
executive compensation.

OVERALL OBJECTIVES AND PHILOSOPHY OF EXECUTIVE COMPENSATION PROGRAM

     The Committee's philosophy is to ensure that the compensation of senior 
management and executive officers is linked directly to improvements in 
financial performance and an increase in stockholder value.  To effect this 
philosophy, the Committee follows the objectives of (i) providing a 
competitive total compensation package that allows the Company to attract, 
retain and motivate key executives, (ii) providing compensation opportunities 
that are linked directly to the financial performance of the Company and that 
align executive remuneration with the interest of the stockholders and (iii) 
integrating executive compensation with the Company's annual and long-term 
business objectives and performance goals.

EXECUTIVE COMPENSATION PROGRAM COMPONENTS

     The Committee reviews on a periodic basis the Company's compensation 
program to ensure that pay levels and incentive opportunities reflect the 
performance of the Company while providing a compensation package that is 
competitive with companies of similar size as the Company.

                                                      -11-

<PAGE>

     BASE SALARY.  Each year the Committee makes a recommendation to the 
Board establishing base salaries for all senior management and executive 
officers. Base salary levels are largely determined through comparisons with 
companies of similar size and complexity as the Company.  Merit increases are 
based on individual performance over the previous year.

     The Committee evaluated the base salary of the Chairman of the Board, 
Chief Executive Officer and President of the Company in June 1996 and 
recommended that his annual compensation level be increased by 15% in order 
to maintain a level comparable with that of chief executive officers of 
companies of similar size and complexity.  In reaching this conclusion, the 
Committee reviewed multiple surveys on executive compensation levels for 
emerging growth companies in various industries.

     ANNUAL INCENTIVE COMPENSATION.  The Company's senior management and 
executive officers are eligible to receive annual cash bonus awards which are 
linked directly to the Company's revenue and operating income and achievement 
of individual goals and nonfinancial corporate goals.  The Committee's 
objective with respect to this plan is to deliver a minimum targeted annual 
incentive of 20% of base salary upon the attainment of a certain threshold 
level of revenue and operating income and achievement of other goals.  Actual 
awards are subject to decrease or increase based on level of attainment and 
are completely at the discretion of the Committee.  The Committee has made 
awards to the executive officers named in the compensation table under this 
plan during the past three years, with the exception of Ms. Ingerly who has 
only received an award for 1996, her first year with the Company.

     The Committee met in January 1997 to review the Company's 1996 
performance and to approve incentive compensation awards, contingent upon 
issuance of audited financial statements.  Based upon performance during the 
year ended December 31, 1996, the Chairman of the Board, Chief Executive 
Officer and President received a bonus representing 40% of his base salary.

     STOCK OPTION PROGRAM.  The Committee strongly believes that compensation 
in the form of stock provides incentive for management to increase 
stockholder value by closely aligning management compensation with the 
performance of the Common Stock.  The Company has adopted the Amended and 
Restated 1992 Stock Option Plan, pursuant to which the Committee may 
authorize the grants of stock options.

     The Committee has authorized grants of stock options, from time to time, 
to executive officers and management of the Company.  The only issuance 
during the year ended December 31, 1996 to executive officers named in the 
compensation table was to Ms. Ingerly, in conjunction with the start of her 
employment with the Company.  Subsequent to December 31, 1996, the Committee 
authorized the issuance of options to purchase 85,000 shares of Common Stock 
at $10.00 per share, the fair market value of the Common Stock at such date, 
to the executive officers named in the compensation table.  These options 
will vest over three years, subject to acceleration to full vesting in one 
year if certain financial goals are attained in 1997.

FUTURE CONSIDERATIONS AND CONCLUSION

     With the Company's recent entry into the public market and revenue and 
earnings growth over the past few years, the Committee is considering 
retaining an outside consultant or firm to review the Company's executive 
compensation program and make recommendations to the Committee to ensure that 
its objectives are being met.  The Committee believes that the total 
compensation program for executives of the Company is competitive with the 
compensation programs provided by other comparable companies.  The Committee 
also believes that any amounts paid under the annual incentive plan 
appropriately relate to corporate and individual performance, yielding awards 
that are directly related to the annual financial and operational results of 
the Company.  Finally, the Committee believes that the Company's stock option 
plans provide opportunities to participants that are consistent with the 
returns that are generated on behalf of the Company's stockholders.

                                       COMPENSATION COMMITTEE OF THE
                                         BOARD OF DIRECTORS

PERFORMANCE PRESENTATION

     The following performance graph compares the performance of the Common 
Stock on an indexed basis to Center for Research in Security Prices ("CRSP") 
Index for The Nasdaq Stock Market - US Companies ("Nasdaq US Companies") and 
a CRSP index of Nasdaq Stock Market health services companies for Nasdaq 
companies with SIC codes beginning with 80 ("Nasdaq Health Services 
Companies").  Information with respect to the Common Stock, the Nasdaq US 
Companies and the Nasdaq Health Services Companies is from May 16, 1996, the 
effective date of the Company's initial public offering.  The graph assumes 
that the value of the investment in the Common Stock and each index was $100 
at May 16, 1996, and that all dividends were reinvested.  The Company will 
provide the names of the companies included in the Nasdaq Health Services 
Companies upon written request to the Investor Relations Department of the 
Company.

                          DESCRIPTION OF COMPANY STOCK PLANS

     Pursuant to applicable federal securities laws, the Company is required 
to furnish to its stockholders in this proxy statement certain information 
with respect to the Amended and Restated Stock Option Plan and the Director 
Stock Option Plan.  For information concerning these plans, see "Proposal 2: 
Approval of the UroCor, Inc. Second Amended and Restated 1992 Stock Option 
Plan", "Proposal 3: Approval of the UroCor, Inc. 1997 Non-Employee Director 
Stock Option Plan" and the summaries set forth below.

     The following summaries do not purport to be complete summaries of the 
Company's stock option plans and are qualified in their entirety by reference 
to the plans.

SUMMARY OF THE AMENDED AND RESTATED STOCK OPTION PLAN

     The Board of Directors adopted the Amended and Restated Stock Option 
Plan on May 5, 1997, subject to the approval by the stockholders of the 
Company.  The Amended and Restated Stock Option Plan authorizes a committee 
of the Board of Directors to issue options intended to qualify as incentive 
stock options ("ISOs"), as defined in Section 422 of the Internal Revenue 
Code of 1986, as amended (the "Code"), and stock options that are not 
intended to conform to the requirements of the Code Section ("Non-ISOs").  
Under the terms of the Amended and Restated Stock Option Plan, the exercise 
price of each ISO cannot be less than 100% of the fair market value of the 
Common Stock at the time of grant, and, in the case of a grant to a 10% 
stockholder, the exercise price may  not be less than 110% of the fair market 
value on the date of grant.  The exercise price of each Non-ISO may not be 
less than the fair market value of the Common Stock on the date of grant.  
Options granted under the Amended and Restated Stock Option Plan may not be 
exercised after the tenth anniversary (or the fifth anniversary in the case 
of an option granted to a 10% stockholder) of their grant.  Payments by 
option holders upon exercise of an option may be made by delivering cash.  
The Amended and Restated Stock Option Plan authorizes:  (i) options to 
acquire up to an aggregate of 1,700,000 shares of Common Stock to be granted; 
(ii) grants of ISOs to eligible employees and grants of Non-ISOs to any 
individual with substantial 

                             -16-

<PAGE>

responsibility for the Company's management and growth, as determined by a 
committee of the Board of Directors; (iii) adjustments to the number and 
class of shares outstanding pursuant to granted options and reserved under 
the Amended and Restated Stock Option Plan in the event of a capital 
adjustment; (iv) an opportunity for outstanding options to be exercised 
subsequent to a merger or disposition of all of the Company's assets and for 
the optionee to receive shares to which he would have been entitled prior to 
such merger or disposition; and (v) grant of options in substitution for 
options held by employees of other corporations who are about to become 
Company employees or whose employer is about to become a parent or subsidiary 
of the Company.  The Company currently has approximately 260 full-time 
employees, including 6 executive officers, each of whom may be eligible to 
receive grants under the Amended and Restated Stock Option Plan.  Other 
persons with substantial responsibility for the Company's management and 
growth may be eligible to receive grants under the Amended and Restated Stock 
Option Plan at the discretion of a committee of the Board of Directors.  A 
complete copy of the Amended and Restated Stock Option Plan is attached to 
this proxy statement as ANNEX A.  The foregoing description of the Amended 
and Restated Stock Option Plan is qualified in its entirety by reference to 
ANNEX A, which is incorporated herein by reference as if fully set forth 
herein.

     The Amended and Restated Stock Option Plan supersedes the 1992 Stock 
Option Plan, under which an aggregate of 1,400,000 shares of Common Stock 
were reserved for issuance.

SUMMARY OF THE DIRECTOR STOCK OPTION PLAN

     The Board of Directors adopted the Director Stock Option Plan on May 5, 
1997, subject to the approval by the stockholders of the Company.  The 
Director Stock Option Plan provides for the automatic grant of stock options 
to non-employee directors.  The Company currently has four non-employee 
directors, each of whom is eligible to receive grants under the Director 
Stock Option Plan.  The purposes of the Director Stock Option Plan are to 
attract and retain the services of experienced and knowledgeable non-employee 
directors of the Company and to provide an incentive for such directors to 
increase their proprietary interests in the Company's long-term success and 
progress.  A committee designated by the Board of Directors shall be the 
administrator of the Director Stock Option Plan.  A complete copy of the 
Director Stock Option Plan is attached to this proxy statement as ANNEX B.  
The following description of the Director Stock Option Plan is qualified in 
its entirety by reference to ANNEX B, which is incorporated herein by 
reference as if fully set forth herein.

     Under the Director Stock Option Plan, an aggregate of 100,000 shares of 
Common Stock have been authorized and reserved for issuance to non-employee 
directors.  The aggregate number of shares of Common Stock for which options 
may be granted under the Director Stock Option Plan may be adjusted based on 
certain anti-dilution provisions contained in the Director Stock Option Plan. 
 On May 5, 1997, each existing non-employee director was granted an option to 
purchase shares of Common Stock based upon their period of service as 
directors at $9.25 per share, the fair market value of such stock on that 
date.  On such date, existing non-employees directors serving (i) since 
January 1, 1989 were granted an option to purchase 10,000 shares of Common 
Stock, (ii) only since January 1, 1994 were granted an option to purchase 
7,500 shares of Common Stock and (iii) only since January 1, 1995 were 
granted an option to purchase 5,000 shares of Common Stock.  On the date of 
election of any new non-employee director, such new non-employee director 
will be granted an option to purchase 10,000 shares of Common Stock at the 
fair market value of such stock on the date of the grant. Additionally, on 
July 1 of each year, beginning July 1, 1998, each non-employee director who 
is a non-employee director on such date will be granted an option to purchase 
5,000 shares of Common Stock at the fair market value of such stock on the 
date that the option is granted.  Each stock option granted to a non-employee 
director will have a ten year term and will be fully vested and exercisable 
on the first anniversary of the date of the grant, assuming continued service 
on the Board of Directors.

FEDERAL TAX CONSEQUENCES

     AMENDED AND RESTATED STOCK OPTION PLAN.  Options granted under the 
Amended and Restated Stock Option Plan may be either ISOs which satisfy the 
requirements of Section 422 of the Code or Non-ISOs which are not intended to 
meet these requirements.  The federal income tax treatment for the two types 
of options differs as follows.

     In general, no tax consequences should result from the grant to or 
exercise by an employee of an ISO under the Amended and Restated Stock Option 
Plan.  The optionee will, however, recognize taxable income in the year in 
which the purchased shares are sold or otherwise made the subject of a 
disposition.

     For federal tax purposes, dispositions are either qualifying or 
disqualifying.  An optionee makes a qualifying disposition of the purchased 
shares if he sells or otherwise disposes of the shares after holding them for 
more than two years after the date the option was granted and more than one 
year after the exercise date.  If the optionee fails to satisfy either of 
these two holding periods prior to the sale or other disposition, a 
disqualifying disposition will result.

     Upon a qualifying disposition of the shares, the optionee will recognize 
long-term capital gain in an amount equal to the excess of (i) the amount 
realized upon the sale or other disposition of the purchased shares over (ii) 
the exercise price paid for such shares.  If there is a disqualifying 
disposition of the shares, the excess of (i) the fair market value of those 
shares on the date the option was exercised over (ii) the exercise price paid 
for the shares generally will be taxable as ordinary income.  Any additional 
gain recognized upon the disposition will be a capital gain.  If, however, 
the disqualifying disposition is a sale or exchange with respect to which a 
loss (if sustained) would be recognized, the amount of ordinary income 
realized by the optionee cannot exceed the amount realized on the sale or 
exchange over the exercise price paid for the shares.

     If the optionee makes a disqualifying disposition of the purchased 
shares, the Company will be entitled to an income tax deduction for the 
taxable years in which the disposition occurs, equal to the excess of (i) the 
fair market value of such shares on the date the option was exercised over 
(ii) the exercise price paid for the shares.  In no other instance will the 
Company be allowed a deduction with respect to the optionee's disposition of 
the purchased shares.

     No taxable income is recognized by an optionee upon the grant of a 
Non-ISO. The optionee will in general recognize ordinary income, in the year 
in which the option is exercised, equal to the excess of the fair market 
value of the purchased shares on the date of exercise over the exercise price 
paid for the shares.  The Company is entitled to a deduction in the same 
amount as the income recognized by the optionee, provided that the Company 
withholds income tax with respect to that amount if the optionee is an 
employee.

     DIRECTOR STOCK OPTION PLAN.  The grant of non-qualified stock options 
under the Director Stock Option Plan will not result in the recognition of 
any taxable income by the director.  A director will recognize ordinary 
income in the year in which the option is exercised equal to the fair market 
value of the purchased shares on the date of exercise over the exercise price 
paid for the shares.  The Company is entitled to a deduction equal to the 
amount recognized as income by the director on the exercise of a 
non-qualified stock option.

                      RELATIONSHIP WITH INDEPENDENT ACCOUNTANTS

     Arthur Andersen LLP served as the Company's principal independent public 
accountants for the year ended December 31, 1996 and has been recommended by 
the Audit Committee to so serve for the current year.  Representatives of 
Arthur Andersen LLP are expected to be present at the annual meeting of 
stockholders, will have the opportunity to make a statement if they so desire 
and will be available to respond to appropriate questions.

               SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934 ("Section 16(a)") 
requires the Company's officers, directors and persons who own more than 10% 
of a registered class of the Company's equity securities to file statements 
on Form 3, Form 4 and Form 5 of ownership and change in ownership with the 
Securities and Exchange Commission.  Officers, directors and greater than 10% 
stockholders are required to furnish the Company with copies of all Section 
16(a) reports which they file.

     Based solely on a review of reports on Forms 3 and 4 and amendments 
thereto furnished to the Company during its most recent fiscal year, reports 
on Form 5 and amendments thereto furnished to the Company with respect to its 
most recent fiscal year and written representations from reporting persons 
that no report on Form 5 was required, the Company believes that, except as 
set forth below, no person who, at any time during 1996, was subject to the 
reporting requirements of Section 16(a) with respect to the Company failed to 
meet such requirements on a timely basis.  Mr. Conrad, a director of the 
Company, purchased shares of Common Stock on May 17, 1996, and was required 
to file a Form 4 on or before June 10, 1996.  The Form 4 was filed on July 
10, 1996.  Dr. O'Dowd, the Company's Medical Director, purchased shares of 
Common Stock on May 16, 1996, and was required to file a Form 4 on or before 
June 10, 1996.  A Form 4 was filed on June 5, 1996, that described other 
transactions but omitted this purchase.  An amended Form 4 was filed on 
December 10, 1996 describing this transaction.

                          PROPOSALS FOR NEXT ANNUAL MEETING

     Any proposals of holders of Common Stock intended to be presented at the 
annual meeting of stockholders of the Company to be held in 1998 must be 
received by the Company at its principal executive offices, 800 Research 
Parkway, Oklahoma City, Oklahoma 73104, no later than January 16, 1998, in 
order to be included in the proxy statement and form of proxy relating to 
that meeting.

                                    OTHER MATTERS

     The management of the Company knows of no other matters that may come 
before the meeting.  However, if any matters other than those referred to 
above should properly come before the meeting, it is the intention of the 
persons named in the enclosed proxy to vote such proxy in accordance with 
their best judgment.

          The cost of solicitation of proxies in the accompanying form will 
be paid by the Company.  In addition to solicitation by use of the mails, 
certain directors, officers or employees of the Company may solicit the 
return of proxies by telephone, telegram or personal interview.

                                     UROCOR, INC.

                  SECOND AMENDED AND RESTATED 1992 STOCK OPTION PLAN

                                     MAY 5, 1997

     1.   PURPOSE.  This Second Amended and Restated 1992 Stock Option Plan 
(the "Plan") of UroCor, Inc. (the "Company"), for certain employees, 
officers, directors and independent contractors performing services for the 
Company is intended to advance the best interest of the Company by providing 
those persons who have substantial responsibility for its management and 
growth with additional incentive and by increasing their proprietary interest 
in the success of the Company -- thereby encouraging them to continue their 
employment or affiliation.

     2.   ADMINISTRATION.  The Plan shall be administered by a committee to 
be appointed by the Board of Directors of the Company (the "Committee"), 
which Committee shall consist of not less than two members of the Board of 
Directors and shall be comprised solely of members of the Board of Directors 
who qualify as both non-employee directors as defined in Rule 16b-3(b)(3) of 
the Securities Exchange Act of 1934, as amended (the "Securities Exchange 
Act") and outside directors within the meaning of Department of Treasury 
Regulations issued under Section 162(m) of the Internal Revenue Code of 1986, 
as amended (the "Code"). The Board of Directors of the Company shall have the 
power to add or remove members of the Committee, from time to time, and to 
fill vacancies arising for any reason.  The Committee shall designate a 
chairman from among its members, who shall preside at all of its meetings, 
and shall designate a secretary, without regard to whether that person is a 
member of the Committee, who shall keep the minutes of the proceedings and 
all records, documents, and data pertaining to its administration of the 
Plan.  Meetings shall be held at any time and place as it shall choose.  A 
majority of the members of the Committee shall constitute a quorum for the 
transaction of business.  The vote of a majority of those members present at 
any meeting shall decide any question brought before that meeting.  In 
addition, the Committee may take any action otherwise proper under the Plan 
by the affirmative vote, taken without a meeting, of a majority of its 
members.  No member of the Committee shall be liable for any act or omission 
of any other member of the Committee or for any act or omission on his own 
part, including but not limited to the exercise of any power or discretion 
given to him under the Plan, except those resulting from his own gross 
negligence or willful misconduct.  All questions of interpretation and 
application of the Plan, or as to options granted under it (the "Options"), 
shall be subject to the determination of a majority of the Committee.  In 
carrying out its authority under this Plan, the Committee shall have full and 
final authority and discretion, including but not limited to the rights, 
powers and authorities, to:  (a) determine the persons to whom and the time 
or times at which Options will be made, (b) determine the number of shares 
and the purchase price of stock covered in each Option, subject to the terms 
of this Plan, (c) determine the terms, provisions and conditions of each 
Option, which need not be identical, (d) accelerate the time at which any 
outstanding Option may be exercised, (e) define the effect, if any, on an 
Option of the death, disability, retirement, or other termination of 
employment of the Optionee, (f) prescribe, amend and rescind rules and 
regulations relating to administration of this Plan, and (g) make all other 
determinations and take all other actions deemed necessary, appropriate, or 
advisable for the proper administration of this Plan. The actions of the 
Committee in exercising all of the rights, powers, and authorities set out in 
this Article and all other Articles of this Plan, when performed in good 
faith and in its sole judgment, shall be final, conclusive and binding on all 
parties. When appropriate the Plan shall be administered in order to qualify 
certain of the Options granted under it as "incentive stock options" 
described in Section 422 of the Code ("Incentive Stock Options").

     3.   DEDICATED SHARES.  The stock subject to the Options and other 
provisions of the Plan shall be shares of the Company's Common Stock, $.01 
par value (the "Stock").  The total number of shares of Stock with respect to 
which Incentive Stock Options may be granted shall be 1,700,000 shares.  The 
maximum number of shares subject to Options which may be issued to any 
Optionee under this Plan during any period of three consecutive years is 
500,000 shares.  The class and aggregate number of shares which may be 
subject to the Options granted hereunder shall be subject to adjustment in 
accordance with the provisions of Paragraph 17 hereof.

     In the event that an outstanding Option expires or is surrendered for 
any reason or terminates by reason of the death or other severance of 
employment of the Optionee, the shares of Stock allocable to the unexercised 
portion of that Option may again be subject to an Option under the Plan.

                                       A-1

<PAGE>

     4.   AUTHORITY TO GRANT OPTIONS.  The Committee may grant the following 
Options at any time during the term of this Plan to any eligible individual 
that it chooses:

     "Incentive Stock Options".  The Committee may grant to an eligible
     employee an Option, or Options, to buy a stated number of shares of Stock
     under the terms and conditions of the Plan, which Option or Options would
     be an "incentive stock option" within the meaning of Section 422 of the
     Code.

     "Nonqualified Stock Options".  The Committee may grant to an eligible
     individual an Option, or Options, to buy a stated number of shares of Stock
     under the terms and conditions of the Plan, which Option or Options would
     not constitute an "incentive stock option" within the meaning of Section
     422 of the Code.

     Each Option granted shall be approved by the Committee.  Subject only to 
any applicable limitations set forth in this Plan, the number of shares of 
Stock to be covered by an Option shall be as determined by the Committee.

     5.   ELIGIBILITY.  The individuals who shall be eligible to receive 
Incentive Stock Options shall be those full-time key employees, including 
officers and directors if they are employees, of the Company, or of any 
parent or subsidiary corporation, as the Committee shall determine during the 
term of this Plan. However, no employee who owns stock possessing more than 
10% of the total combined voting power of all classes of stock of the 
corporation employing the employee or of its parent or subsidiary corporation 
shall be eligible to receive an Incentive Stock Option unless at the time 
that the Option is granted the option price is at least 110% of the fair 
market value (as defined in this Section 5) of the Stock at the time the 
Option is granted and the Option by its own terms is not exercisable after 
the expiration of five years from the date the Option is granted.

     An employee will be considered as owning the stock owned, directly or 
indirectly, by or for his brothers and sisters (whether by the whole or half 
blood), spouse, ancestors, and lineal descendants.  Stock owned, directly or 
indirectly, by or for a corporation, partnership, estate or trust will be 
considered as being owned proportionately by or for its shareholders, 
partners or beneficiaries.  For all purposes of this Plan, a parent 
corporation is any corporation (other than the Company) in an unbroken chain 
of corporations ending with the Company if, on the date of grant of the 
Option in question, each of the corporations other than the Company owns 
stock possessing 50% or more of the total combined voting power of all 
classes of stock in one of the other corporations in that chain; and a 
subsidiary corporation is any corporation in an unbroken chain of 
corporations beginning with the Company if, on the date of grant of the 
Option in question, each of the corporations, other than the last corporation 
in the chain, owns stock possessing 50% or more of the total combined voting 
power of all classes of stock in one of the other corporations in that chain.

     The individuals who shall be eligible to receive Nonqualified Stock 
Options shall be such individuals as the Committee shall determine during the 
term of this Plan.

     No individual shall be eligible to receive an Option under the Plan 
while that individual is a member of the Committee.

     As used in this Plan, "fair market value" of the Stock as of any date 
means (a) the closing price on that date on the principal securities exchange 
on which the Stock is listed; or (b) if the Stock is not listed on a 
securities exchange, the closing price of the Stock on that date as reported 
on The National Association of Securities Dealers (the "NASD") Automated 
Quotation System ("Nasdaq") Stock Market's National Market; or (c) if the 
Stock is not listed on The Nasdaq Stock Market's National Market, the average 
of the high and low bid quotations for the Stock on that date as reported by 
the National Quotation Bureau Incorporated; or (d) if none of the foregoing 
is applicable, an amount, at the election of the Committee equal to (x) the 
average between the closing bid and ask prices per share of Stock on the last 
preceding date on which those prices were reported or (y) the value of the 
Stock as determined in good faith by the Committee in its sole discretion.

                                       A-2

<PAGE>

     6.   OPTION PRICE.  The price at which shares may be purchased pursuant 
to an Incentive Stock Option shall be not less than the fair market value of 
the shares of Stock on the date the Option is granted.  The price at which 
shares may be purchased pursuant to a Nonqualified Stock Option shall be not 
less than the fair market value of the shares of Stock on the date the Option 
is granted. The Committee in its discretion may provide that the price at 
which shares may be purchased shall be more than the minimum price required.  
If an employee owns stock possessing more than 10% of the total combined 
voting power of all classes of stock of the corporation employing the 
employee or of its parent or subsidiary corporation, the option price at 
which shares may be purchased under an Incentive Stock Option shall be not 
less than 110% of the fair market value of the Stock on the date the Option 
is granted.

     7.   DURATION OF OPTIONS.  No Incentive Stock Option shall be 
exercisable after the expiration of ten years from the date such Option is 
granted.  The Committee in its discretion may provide that the Option shall 
be exercisable throughout the ten-year period or during any lesser period of 
time commencing on or after the date of grant of the Option and ending upon 
or before the expiration of the ten-year period.  If an employee owns stock 
possessing more than 10% of the total combined voting power of all classes of 
stock of the corporation employing the employee or of its parent or 
subsidiary corporation, no Incentive Stock Option shall be exercisable after 
the expiration of five years from the date such Option is granted.  No 
Nonqualified Stock Option shall be exercisable after the expiration of ten 
years from the date such Option is granted.  The Committee in its discretion 
may provide that the Option shall be exercisable throughout the ten-year 
period or during any lesser period of time commencing on or after the date of 
grant of the Option and ending upon or before the expiration of the ten-year 
period.

     8.   $100,000 LIMITATION ON INCENTIVE STOCK OPTIONS.  To the extent that 
the aggregate fair market value (determined as of the time an Incentive 
Option is granted) of the Stock with respect to which Incentive Options first 
become exercisable by the Optionee during any calendar year (under this Plan 
and any other incentive stock option plan(s) of the Company or any parent 
corporation or subsidiary corporation) exceeds $100,000, the Incentive 
Options shall be treated as Nonqualified Options.  In making this 
determination, Incentive Options shall be taken into account in the order in 
which they were granted.

     9.   AMOUNT EXERCISABLE.  Each Option may be exercised, so long as it is 
valid and outstanding, from time to time in part or as a whole, in the manner 
and subject to the conditions that the Committee in its discretion may 
provide in the Option agreement.  However, the Committee in its absolute 
discretion may accelerate the time at which any outstanding Option may be 
exercised.  Notwithstanding any provision of this Plan or an Option agreement 
to the contrary, no Option awarded under this Plan after May 5, 1997, may be 
exercised before this amendment and restatement of this Plan is approved by 
the stockholders of the Company.

     10.  EXERCISE OF OPTIONS.  Each Option shall be exercised by the 
delivery of written notice to the Company setting forth the number of shares 
of Stock with respect to which the Option is to be exercised, together with 
cash, certified check, bank draft or postal or express money order payable to 
the order of the Company for an amount equal to the exercise price of such 
shares, and specifying the address to which the certificates for such shares 
are to be mailed.  As promptly as practicable after receipt of written 
notification and payment, the Company shall deliver to the Optionee 
certificates for the number of shares with respect to which the Option has 
been exercised, issued in the Optionee's name. Delivery of the shares shall 
be deemed effected for all purposes when a stock transfer agent of the 
Company shall have deposited the certificates in the United States mail, 
addressed to the Optionee, at the address specified by the Optionee in his 
notice of exercise.

     11.  TRANSFERABILITY OF OPTIONS.  Options shall not be transferable by 
the Optionee except by will or under the laws of descent and distribution, 
and shall be exercisable, during his lifetime, only by him.

     12.  TERMINATION OF EMPLOYMENT OR AFFILIATION OF OPTIONEE.  Except as 
otherwise expressly provided herein or in the Option agreement, Incentive 
Stock Options shall terminate at 5:00 p.m., Oklahoma City time, on the 60th 
day immediately following the date of severance of employment of the Optionee 
from the Company for any reason, with or without cause, other than death or 
retirement for age or disability under the then established rules of the 
Company, and Nonqualified Stock Options shall terminate at 5:00 p.m., 
Oklahoma City time, on the 60th day immediately following the date of the 
severance of the employment or affiliation relationship between the Company 
and the Optionee for any reason with or without cause other than death or 
retirement for age or disability under the then established rules of the 
Company.  Whether authorized leave of absence or absence on military or 
government service shall constitute severance of the employment or 
affiliation relationship between the Company and the Optionee shall be 

                                       A-3

<PAGE>

determined by the Committee at that time.  After such severance of an 
Optionee holding either an Incentive Stock Option or Nonqualified Stock 
Option, such Optionee shall have the right, at any time prior to such 
termination, to exercise the Option to the extent to which he was entitled to 
exercise it immediately prior to his severance.

     If, before the expiration of an Incentive Stock Option or a Nonqualified 
Stock Option held by an employee of the Company, the Optionee shall be 
retired from the employ of the Company because of his age or disability under 
the then established rules of the Company, such Incentive Stock Option or 
Non-incentive Stock Option, as the case may be, shall terminate on the 
earlier of such date of expiration or one day less than three months after 
his retirement.  If, before the expiration of a Nonqualified Stock Option 
held by an Optionee who is not an employee of the Company, the Optionee's 
affiliation with the Company shall be severed for age or disability under the 
then established rules of the Company, such Nonqualified Stock Option shall 
terminate on the earlier of such date of expiration or one day less than 
three months after his severance of affiliation. In the event of retirement 
for age or disability, or severance of affiliation for age or disability, as 
the case may be, the Optionee shall have the right prior to the termination 
of the Option to exercise the Option to the extent to which he was entitled 
to exercise it immediately prior to such retirement or severance of 
affiliation for age or disability, as the case may be.

     In the event of the death of a holder of an Incentive Stock Option while 
in the employ of the Company or during the period after the retirement of the 
employee for age or disability and before the date of expiration of the 
Option, such Option will terminate on the earlier of such date of expiration 
or one year following the date of his death.  In the event of the death of a 
holder of a Nonqualified Stock Option while in the employ of, or affiliated 
with, the Company or during the period after the retirement of the holder for 
age or disability or after the severance of his affiliation with the Company 
for age or disability, as the case may be, and before the date of expiration 
of the Option, the Option will terminate on the earlier of such date of 
expiration or one year following the date of his death.  After the death of 
an Optionee holding either an Incentive Stock Option or a Nonqualified Stock 
Option, his executors, administrators or any persons to whom his Option may 
be transferred by will or by the laws of descent and distribution shall have 
the right, at any time prior to such termination, to exercise the Option to 
the extent to which he was entitled to exercise it immediately prior to his 
death.

     An employment relationship between the Company and the Optionee shall be 
deemed to exist during any period in which the Optionee is employed by the 
Company, by any parent or subsidiary corporation, by a corporation issuing or 
assuming a stock option in a transaction to which Section 424(a) of the Code 
applies, or by a parent or subsidiary corporation of the corporation issuing 
or assuming a stock option.  For this purpose, the phrase "corporation 
issuing or assuming a stock option" shall be substituted for the word 
"Company" in the definitions of parent and subsidiary corporations in Section 
5 and the parent-subsidiary relationship shall be determined at the time of 
the corporate action described in Section 424(a) of the Code.

     13.  FORFEITURES.  Notwithstanding any other provision of this Plan, if 
the Committee finds by a majority vote, that the Optionee, before or after 
termination of his employment or affiliation with the Company or any parent 
or subsidiary corporation (as used in this Section, the "Employer"), 
committed fraud, embezzlement, theft, commission of felony, or proven 
dishonesty in the course of his employment by or affiliation with the 
Employer which conduct damaged the Employer, or for disclosing trade secrets 
of the Employer, then any outstanding options which have not been exercised 
by the Optionee will be forfeited.  The decision of the Committee as to the 
cause of an Optionee's discharge, the damage done to the Employer and the 
extent of the Optionee's competitive activity will be final.  No decision of 
the Committee, however, will affect the finality of the discharge of the 
Optionee by the Employer.

     14.  REQUIREMENTS OF LAW.  The Company shall not be required to sell or 
issue any shares under any Option if issuing the shares shall constitute a 
violation by the Optionee or the Company of any provisions of any law or 
regulation of any governmental authority.  Each Option granted under this 
Plan shall be subject to the requirements that, if at any time the Board of 
Directors of the Company or the Committee shall determine that the listing, 
registration or qualification of the shares upon any securities exchange or 
under any state or federal law of the United states or of any other country 
or governmental subdivision, or the consent or approval of any governmental 
regulatory body, or investment or other representations, are necessary or 
desirable in connection with the issue or purchase of shares subject to an 
Option, that Option shall not be exercised in whole or in part unless the 
listing, registration, qualification, consent, approval or representations 
shall have been effected or obtained free of any conditions not acceptable to 
the Committee.  In connection with any applicable statute or regulation 
relating to the registration of securities, upon exercise of any Option, the 
Company shall not be required to issue any Stock unless the Committee has 
received evidence satisfactory 

                                       A-4

<PAGE>

to it to the effect that the holder of that Option will not transfer the 
Stock except in accordance with applicable law, including receipt of an 
opinion of counsel satisfactory to the Company to the effect that any 
proposed transfer complies with applicable law.  Any determination by the 
Committee on these matters shall be final, binding and conclusive.  In the 
event the shares issuable on exercise of an Option are not registered under 
applicable securities laws of any country or any political subdivision the 
Company may imprint on the certificate for such shares the following legend 
or any other legend which counsel for the Company considers necessary or 
advisable to comply with applicable law:

     "The shares of stock represented by this certificate have not been
     registered under the Securities Act of 1933 or under the securities laws of
     any state and may not be sold or transferred except upon registration or
     upon receipt by the Company of an opinion of counsel satisfactory to the
     Company, in form and substance satisfactory to the Company, that
     registration is not required for a sale or transfer."

The Company may, but shall in no event be obligated to, register any 
securities covered by this Plan under applicable securities laws of any 
country or political subdivision (as now in effect or as later amended) and, 
in the event any shares are registered, the Company may remove any legend on 
certificates representing those shares.  The Company shall not be obligated 
to take any other affirmative action in order to cause the exercise of an 
Option or the issuance of shares under the Option to comply with any law or 
regulation or any governmental authority.

     15.  NO RIGHTS AS STOCKHOLDER.  No Optionee shall have rights as a 
stockholder with respect to shares covered by his Option until the date a 
stock certificate is issued for the shares.  Except as provided in Section 
17, no adjustment for dividends, or other matters shall be made if the record 
date is prior to the date the certificate is issued.

     16.  EMPLOYMENT OR AFFILIATION OBLIGATION.  The granting of any Option 
shall not impose upon the Company any obligation to employ or become 
affiliated with or continue to employ or be affiliated with any Optionee.  
The right of the Company to terminate the employment or affiliation of any 
person shall not be diminished or affected by reason of the fact that an 
Option has been granted to him.

     17.  CHANGES IN THE COMPANY'S CAPITAL STRUCTURE.  The existence of 
outstanding Options shall not affect in any way 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 Company's capital 
structure or its business, or any merger or consolidation of the Company, or 
any issue of bonds, debentures, preferred or prior preference stock ahead of 
or affecting the Stock or the rights of the 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, whether of a 
similar character or otherwise.

     If the Company shall effect a subdivision or consolidation of shares or 
other capital readjustment, the payment of a stock dividend, or other 
increase or reduction of the number of shares of the Stock outstanding, 
without receiving compensation for it in money, services or property, then 
(a) the number, class and per share price of shares of stock subject to 
outstanding Options under this Plan shall be appropriately adjusted in a 
manner as to entitle an Optionee to receive upon exercise of an Option, for 
the same aggregate cash consideration, the same total number and class or 
classes of shares as he would have received had he exercised his Option in 
full immediately prior to the event requiring the adjustment; and (b) the 
number and class of shares then reserved for issuance under the Plan shall be 
adjusted by substituting for the total number and class of shares of stock 
then reserved for the number and class or classes of shares of stock that 
would have been received by the owner of an equal number of outstanding 
shares of Stock as the result of the event requiring the adjustment.

     If the Company merges or consolidates with another corporation, whether 
or not the Company is a surviving corporation, or if the Company is 
liquidated or sells or otherwise disposes of substantially all its assets 
while unexercised Options remain outstanding under the Plan, or if any 
"person" (as that term is used in Section 13(d) and 14(d)(2) of the 
Securities Exchange Act) is or becomes the beneficial owner, directly or 
indirectly, of securities of the Company representing greater than 50% of the 
combined voting power of the Company's then outstanding securities, after the 
effective date of the merger, consolidation, liquidation, sale or other 
disposition, or change in beneficial ownership, as the case may be, each 
holder of an outstanding Option shall be entitled, upon exercise of an 
Option, to receive, in lieu of shares of Stock, the number and class or 
classes of shares of stock or other securities or property to which the 
holder would have been entitled if, immediately prior to the merger, 
consolidation, liquidation, sale or other 

                                       A-5

<PAGE>

disposition, or change in beneficial ownership, the holder had been the 
holder of record of the number of shares of Stock equal to the entire number 
of shares as to which the Option may be exercised regardless of and without 
giving effect to any limitations set out in or imposed pursuant to this Plan 
or any Option granted hereunder.

     Except as expressly provided before in this Plan, the issue by the 
Company of shares of stock of any class, or securities convertible into 
shares of stock of any class, for cash or property, or for labor or services 
either upon direct sale or upon the exercise of rights or warrants to 
subscribe for shares, or upon conversion of shares or obligations of the 
Company convertible into shares or other securities, shall not affect, and no 
adjustment by reason of it shall be made with respect to, the number or price 
of shares of Stock then subject to outstanding Options.

     18.  SUBSTITUTION OPTIONS.  Options may be granted under this Plan from 
time to time in substitution for stock options held by employees of other 
corporations who are about to become employees of the Company, or whose 
employer is about to become a parent or subsidiary corporation, conditioned 
in the case of an Incentive Stock Option upon the employee becoming an 
employee as the result of a merger or consolidation of the Company with 
another corporation, or the acquisition by the Company of substantially all 
the assets of another corporation, or the acquisition by the Company of at 
least 50% of the issued and outstanding stock of another corporation as the 
result of which it becomes a subsidiary of the Company.  The terms and 
conditions of the substitute Options granted may vary from the terms and 
conditions of this Plan to the extent the Board of Directors of the Company 
at the time of grant may deem appropriate to conform, in whole or in part, to 
the provisions of the stock options in substitution for which they are 
granted.  But with respect to Incentive Stock Options, no variation shall be 
made which will affect the status of any substitute option as an "incentive 
stock option" under Section 422 of the Code.

     19.  AMENDMENT OR TERMINATION OF PLAN.  The Board of Directors may 
modify, revise or terminate this Plan at any time and from time to time.  
However, without the further approval of the holders of at least a majority 
of the outstanding shares of voting stock, or if the provisions of the 
corporate charter, by-laws or applicable state law prescribe a greater degree 
of stockholder approval for this action, without the degree of stockholder 
approval thus required, the Board of Directors may not (a) change the 
aggregate number of shares which may be issued under Options pursuant to the 
provisions of this Plan; (b) reduce the Option price permitted for Incentive 
Stock Options; (c) extend the term during which an Incentive Stock Option may 
be exercised or the termination date of this Plan; (d) change the class of 
employees eligible to receive Incentive Stock Options; or (e) (i) materially 
increase the benefits accruing to participants under the Plan, (ii) 
materially increase the number of securities which may be issued under the 
Plan or (iii) materially modify the requirements as to eligibility for 
participation in the Plan.  The Board of Directors, however, shall have the 
power to make all changes in the Plan and in the regulations and 
administrative provisions under the Plan or in any outstanding Option as in 
the opinion of counsel for the Company may be necessary or appropriate from 
time to time to enable any Option granted pursuant to the Plan to qualify as 
an incentive stock option under Section 422 of the Code and the regulations 
which may be issued under that Section as in existence from time to time.  
All Options granted under this Plan shall be subject to the terms and 
provisions of this Plan and any amendment, modification or revision of this 
Plan shall be deemed to amend, modify or revise all Options outstanding under 
this Plan at the time of the amendment, modification or revision.  In the 
event this Plan is terminated by action of the Board of Directors, all 
Options outstanding under this Plan may be terminated.

     20.  WRITTEN AGREEMENT.  Each Option granted under this Plan shall be 
embodied in a written agreement, which shall be subject to the terms and 
conditions prescribed above, and shall be signed by the Optionee and by an 
officer of the Company on behalf of the Committee and the Company.  Each 
Option agreement shall contain any other provisions that the Committee in its 
discretion shall deem advisable which are not inconsistent with the terms of 
this Plan.

     21.  INDEMNIFICATION OF THE COMMITTEE AND THE BOARD OF DIRECTORS.  The 
Company will, to the fullest extent permitted by law, indemnify, defend and 
hold harmless any person who at any time is a party or is threatened to be 
made a party to any threatened, pending or completed action, suit or 
proceeding (whether civil, criminal, administrative or investigative) in any 
way relating to or arising out of this Plan or any Option or Options granted 
under it by reason of the fact that that person is or was at any time a 
director of the Company or a member of the Committee against judgments, 
fines, penalties, settlements and reasonable expenses (including attorneys' 
fees) actually incurred by that person in connection with the action, suit or 
proceeding.  This right of indemnification will inure to the benefit of the 
heirs, executors and administrators of each person to be protected and is in 
addition to all other rights to which that person may be entitled by virtue 
of the by-laws of the Company or as a matter of law, contract or otherwise.

                                       A-6

     22.  TAX WITHHOLDING.  The Company shall be entitled to deduct from 
other compensation payable to each employee any sums required by federal, 
state or local tax law to be withheld with respect to the grant or exercise 
of an Option. In the alternative, the Company may require the employee (or 
other individual exercising the Option) to pay the sum directly to the 
Company. If the employee (or other individual exercising the Option) is 
required to pay the sum directly, payment in cash or by check of such sums 
for taxes shall be delivered within ten days after the date of exercise. The 
Company shall have no obligation upon exercise of any Option until payment 
has been received, unless withholding (or offset against a cash payment) as 
of or prior to the date of exercise is sufficient to cover all sums due with 
respect to that exercise. The Company shall not be obligated to advise an 
employee of the existence of the tax or the amount which the employer 
corporation will be required to withhold.

     23.  GENDER.  If the context requires, words of one gender when used in 
this Plan shall include the others and words used in the singular or plural 
shall include the other.

     24.  HEADINGS.  Headings of Sections are included for convenience of 
reference only and do not constitute part of this Plan and shall not be used 
in construing the terms of this Plan.

     25.  OTHER OPTIONS.  The grant of an Option shall not confer upon an 
Optionee the right to receive any future or other Options under this Plan, 
whether or not Options may be granted to similarly situated Optionees, or the 
right to receive future Options upon the same terms or conditions as 
previously granted.

     26.  ARBITRATION OF DISPUTES.  Any controversy arising out of or 
relating to this Plan or an Option Agreement shall be resolved by arbitration 
conducted pursuant to the arbitration rules of the American Arbitration 
Association.  The arbitration shall be final and binding on the parties.

     27.  GOVERNING LAW.  The provisions of this Plan shall be construed, 
administered, and governed under the laws of the State of Delaware.

     28.  EFFECTIVE DATE OF PLAN.       This Plan restates and integrates, 
and also amends, the UroCor, Inc. 1992 Amended and Restated Stock Option Plan 
adopted effective March 15, 1996.

     The Plan shall become effective and shall be deemed to have been adopted 
on May 5, 1997, if within one year of that date it has been approved by the 
holders of at least a majority of the outstanding shares of voting stock of 
the Company voting in person or by proxy at a duly held stockholders' 
meeting, or if the provisions of the corporate charter, by-laws or applicable 
state law prescribe a greater degree of stockholder approval for this action, 
the approval by the holders of that percentage, at a duly held meeting of 
stockholders.

     No Options shall be granted pursuant to the Plan after September 24, 
2002.

                                 UROCOR, INC.
                 1997 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN
                                 MAY 5, 1997

     1.   PURPOSE.  This 1997 Non-Employee Director Stock Option Plan (this 
"Plan") of UroCor, Inc., a Delaware corporation (the "Company"), is adopted, 
subject to stockholder approval, for the benefit of the directors of the 
Company who at the time of their service are not employees of the Company or 
any of its subsidiaries ("Non-Employee Directors"), and is intended to 
advance the interests of the Company by providing the Non-Employee Directors 
with additional incentive to serve the Company by increasing their 
proprietary interest in the success of the Company.

     2.   ADMINISTRATION.  This Plan shall be administered by a committee to 
be appointed by the Board of Directors of the Company (the "Committee"), 
which Committee shall consist of not less than two members of the Board of 
Directors and shall be comprised solely of members of the Board of Directors 
who qualify as non-employee directors as defined in Rule 16b-3(b)(3) of the 
Securities Exchange Act of 1934, as amended (the "Securities Exchange Act").  
For the purposes of this Plan, a majority of the members of the Committee 
shall constitute a quorum for the transaction of business, and the vote of a 
majority of those members present at any meeting shall decide any question 
brought before that meeting.  No member of the Committee shall be liable for 
any act or omission of any other member of the Committee or for any act or 
omission on his own part, including (without limitation) the exercise of any 
power or discretion given to him under this Plan, except those resulting from 
his own gross negligence or willful misconduct.  All questions of 
interpretation and application of this Plan, or as to options granted 
hereunder (the "Options"), shall be subject to the determination, which shall 
be final and binding, of a majority of the whole Committee.  Notwithstanding 
the above, the selection of Non-Employee Directors to whom Options are to be 
granted, the number of shares subject to any Option, the exercise price of 
any Option and the term of any Option shall be as hereinafter provided and 
the Committee shall have no discretion as to such matters.

     3.   OPTION SHARES.  The stock subject to the Options and other 
provisions of this Plan shall be shares of the Company's Common Stock, $.01 
par value per share (or such other par value as may be designated by act of 
the Company's stockholders, the "Common Stock").  The total amount of Common 
Stock with respect to which Options may be granted shall not exceed 100,000 
shares in the aggregate; PROVIDED, that the class and aggregate number of 
shares which may be subject to the Options granted hereunder shall be subject 
to adjustment in accordance with the provisions of Section 12 of this Plan.  
Such shares may be treasury shares or authorized but unissued shares.

     If any outstanding Option for any reason shall expire or terminate by 
reason of the death of the optionee or the fact that the optionee ceases to 
be a director, the surrender of any such Option, or any other cause, the 
shares of Common Stock allocable to the unexercised portion of such Option 
may again be subject to an Option under this Plan.

Quotation System ("Nasdaq") Stock Market's National Market, the closing price 
on such day on the principal securities exchange or on The Nasdaq Stock

     5.   DURATION OF OPTIONS.  Each Option granted under this Plan shall be 
exercisable for a term of nine years from the date such Option first becomes 
exercisable pursuant to Section 6 hereof, subject to earlier termination as 
provided in Section 9 of this Plan.

     6.   AMOUNT EXERCISABLE.  Each Option granted under this Plan may be 
exercised in whole or in part at any time commencing one year after the grant 
thereof.

     7.   EXERCISE OF OPTIONS.  An optionee may exercise his Option by 
delivering to the Company a written notice stating (a) that such optionee 
wishes to exercise such Option on the date such notice is so delivered, (b) 
the number of shares of stock with respect to which such Option is to be 
exercised and (c) the address to which the certificate representing such 
shares of stock should be mailed.  To be effective, such written notice shall 
be accompanied by payment of the Option Price of each of such shares of 
stock.  Each such payment shall be made by cash, cashier's check or bank 
draft drawn on a national banking association or postal or express money 
order, payable to the order of the Company in United States dollars.

     As promptly as practicable after the receipt by the Company of (a) such 
written notice from the optionee and (b) payment, in the form required by the 
foregoing provisions of this Section 7, of the Option Price of the shares of 
stock with respect to which such Option is to be exercised, a certificate 
representing the number of shares of stock with respect to which such Option 
has been so exercised registered in the name of such optionee, shall be 
delivered to such optionee, provided that such delivery shall be considered 
to have been made when such certificate shall have been mailed, postage 
prepaid, to such optionee at the address specified for such purpose in such 
written notice from the optionee to the Company.

     8.   TRANSFERABILITY OF OPTIONS.  Options shall not be transferable by 
the optionee otherwise than by will or under the laws of descent and 
distribution.

     9.   TERMINATION.  Except as may be otherwise expressly provided in this 
Plan, each Option, to the extent it shall not have been exercised previously, 
shall terminate on the earlier of the following:

          (a)  At 5:00 p.m., Oklahoma City time, on the last day of the 60-day
     period commencing on the date on which the optionee ceases to be a member
     of the Company's Board of Directors, for any reason other than the death or
     permanent disability of the optionee, during which period the optionee
     shall be entitled to exercise all Options held by the optionee on the date
     on which the optionee ceased to be a member of the Company's Board of
     Directors which could have been exercised on such date;

          (b)  On the last day of the one-year period commencing on the date of
     the optionee's death while serving as a member of the Company's Board of
     Directors, during which period the executor or administrator of the
     optionee's estate or the person or persons to whom the optionee's Option
     shall have been transferred by will or the laws of descent or distribution,
     shall be entitled to exercise all Options in respect of the number of
     shares that the optionee would have been entitled to purchase had the
     optionee exercised such Options on the date of his death; or

          (c)  Ten years after the date of grant of such Option.

     10.  REQUIREMENTS OF LAW.  The Company shall not be required to sell or 
issue any shares under any Option if the issuance of such shares shall 
constitute a violation by the optionee or the Company of any provisions of 
any law or regulation of any governmental authority.  Each Option granted 
under this Plan shall be subject to the requirements that, if at any time the 
Board of Directors of the Company or the Committee shall determine that the 
listing, registration or qualification of the shares subject thereto upon any 
securities exchange or under any state or federal law of the United States or 
of any other country or governmental subdivision thereof, or the consent or 
approval of any governmental regulatory body, or investment or other 
representations, are necessary or desirable in connection with the issue or 
purchase of shares subject thereto, no such Option may be exercised in whole 
or in part unless such listing, registration, qualification, consent, 
approval or representation shall have been effected or obtained free of any 
conditions 

                                       B-3

<PAGE>

not acceptable to the Board of Directors.  Any determination in this 
connection by the Committee shall be final, binding and conclusive.  If the 
shares issuable on exercise of an Option are not registered under the 
Securities Act of 1933, as amended (the "Securities Act"), the Company may 
imprint on the certificate for such shares the following legend or any other 
legend which counsel for the Company considers necessary or advisable to 
comply with the Securities Act:

     THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933 OR UNDER THE SECURITIES LAWS OF
     ANY STATE AND MAY NOT BE SOLD OR TRANSFERRED EXCEPT UPON SUCH REGISTRATION
     OR UPON RECEIPT BY THE CORPORATION OF AN OPINION OF COUNSEL SATISFACTORY TO
     THE CORPORATION, IN FORM AND SUBSTANCE SATISFACTORY TO THE CORPORATION,
     THAT REGISTRATION IS NOT REQUIRED FOR SUCH SALE OR TRANSFER.

The Company may, but shall in no event be obligated to, register any 
securities covered hereby pursuant to the Securities Act (as now in effect or 
as hereafter amended) and, if any shares are so registered, the Company may 
remove any legend on certificates representing such shares.  The Company 
shall not be obligated to take any other affirmative action to cause the 
exercise of an Option or the issuance of shares pursuant thereto to comply 
with any law or regulation of any governmental authority.

     11.  NO RIGHTS AS STOCKHOLDER.  No optionee shall have rights as a 
stockholder with respect to shares covered by his Option until the date of 
issuance of a stock certificate for such shares; and, except as otherwise 
provided in Section 12 hereof, no adjustment for dividends, or otherwise, 
shall be made if the record date therefor is prior to the date of issuance of 
such certificate.

     12.  CHANGES IN THE COMPANY'S CAPITAL STRUCTURE.  The existence of 
outstanding Options shall not affect in any way 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 Company's capital 
structure or its business, or any merger or consolidation of the Company, or 
any issue of bonds, debentures, preferred or prior preference stock ahead of 
or affecting the Common Stock or the rights thereof, 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, whether of a 
similar character or otherwise.

     If the Company shall effect a subdivision or consolidation of shares or 
other capital readjustment, the payment of a stock dividend or other increase 
or reduction of the number of shares of Common Stock outstanding, without 
receiving compensation therefor in money, services or property, then (a) the 
number, class and per share price of shares of stock subject to outstanding 
Options hereunder shall be appropriately adjusted in such a manner as to 
entitle an optionee to receive upon exercise of an Option, for the same 
aggregate cash consideration, the same total number and class or classes of 
shares as he would have received had he exercised his Option in full 
immediately prior to the event requiring the adjustment; and (b) the number 
and class of shares then reserved for issuance under this Plan and the number 
of shares to be subject to the grants to be made pursuant to Subsections 
4(a)(ii), 4(b)(i) and 4(b)(ii) shall be adjusted by substituting for the 
total number and class of shares of stock then reserved or subject to grant 
the number and class or classes of shares of stock that would have been 
received by the owner of an equal number of outstanding shares of Common 
Stock as the result of the event requiring the adjustment, disregarding any 
fractional shares.

     If the Company merges or consolidates with another corporation, whether 
or not the Company is a surviving corporation, or if the Company is 
liquidated or sells or otherwise disposes of substantially all its assets 
while unexercised Options remain outstanding under this Plan, or if any 
"person" (as that term is used in Section 13(d) and 14(d)(2) of the 
Securities Exchange Act) is or becomes the beneficial owner, directly or 
indirectly, of securities of the Company representing greater than 50% of the 
combined voting power of the Company's then outstanding securities, after the 
effective date of such merger, consolidation, liquidation, sale or other 
disposition, as the case may be, each holder of an outstanding Option shall 
be entitled, upon exercise of such Option, to receive, in lieu of shares of 
Common Stock, the number and class or classes of shares of such stock or 
other securities or property to which such holder would have been entitled 
if, immediately prior to such merger, consolidation, liquidation, sale or 
other disposition, such holder had been the holder of record of a number of 
shares of Common Stock equal to the number of shares as to which such Option 
may be exercised.

                             B-4

     Except as otherwise expressly provided in this Plan, the issue by the 
Company of shares of stock of any class, or securities convertible into 
shares of stock of any class, for cash or property, or for labor or services 
either upon direct sale or upon the exercise of rights or warrants to 
subscribe therefor, or upon conversion of shares or obligations of the 
Company convertible into such shares or other securities, shall not affect, 
and no adjustment by reason thereof shall be made with respect to, the number 
or price of shares of Common Stock then subject to outstanding Options.

     13.  AMENDMENT OR TERMINATION OF PLAN.  The Board of Directors may 
modify, revise or terminate this Plan at any time and from time to time; 
PROVIDED, HOWEVER, that without the further approval of the holders of at 
least a majority of the outstanding shares of voting stock, or if the 
provisions of the corporate charter, bylaws or applicable state law 
prescribes a greater degree of stockholder approval for this action, without 
the degree of stockholder approval thus required, the Board of Directors may 
not (a) materially increase the benefits accruing to participants under this 
Plan; (b) materially increase the number of shares of Common Stock which may 
be issued under this Plan; or (c) materially modify the requirements as to 
eligibility for participation in this Plan, unless, in each such case, the 
Board of Directors of the Company shall have obtained an opinion of legal 
counsel to the effect that stockholder approval of the amendment is not 
required (x) by law, (y) by the rules and regulations of, or any agreement 
with, the National Association of Securities Dealers, Inc. or (z) to make 
available to the optionee with respect to any option granted under this Plan, 
the benefits of Rule 16b-3 of the Rules and Regulations under the Securities 
Exchange Act, or any similar or successor rule. In addition, the provisions 
of this Plan may not be amended more than once every six months other than to 
comport with changes in the Internal Revenue Code of 1986, as amended, the 
Employee Retirement Income Security Act of 1974, as amended, or the rules 
thereunder.  All Options granted under this Plan shall be subject to the 
terms and provisions of this Plan and any amendment, modification or revision 
of this Plan shall be deemed to amend, modify or revise all Options 
outstanding under this Plan at the time of such amendment, modification or 
revision.  If this Plan is terminated by action of the Board of Directors, 
all outstanding Options may be terminated.

     14.  WRITTEN AGREEMENT.  Each Option granted hereunder shall be embodied 
in a written option agreement, which shall be subject to the terms and 
conditions prescribed above, and shall be signed by the optionee and by the 
appropriate officer of the Company for and in the name and on behalf of the 
Company.  Such an option agreement shall contain such other provisions as the 
Committee in its discretion shall deem advisable.

     15.  INDEMNIFICATION OF COMMITTEE AND BOARD OF DIRECTORS.  The Company 
shall, to the fullest extent permitted by law, indemnify, defend and hold 
harmless any person who at any time is a party or is threatened to be made a 
party to any threatened, pending or completed action, suit or proceeding 
(whether civil, criminal, administrative or investigative) in any way 
relating to or arising out of this Plan or any Option or Options granted 
hereunder by reason of the fact that such person is or was at any time a
