ten percent of a registered class of the Company's equity securities, to file
reports of ownership and changes in ownership with the Securities and Exchange
Commission.  Officers, directors and greater than ten-percent stockholders are
required by the regulations promulgated under Section 16(a) to furnish the

COMPENSATION OF DIRECTORS

         Employee directors of the Company do not receive any additional
compensation for their services as a director of the Company.  The Company pays
an annual retainer of $15,000 to each non-employee director.  In addition, each
non-employee director receives $1,000 for each Board of Directors meeting
attended and $750 for each committee meeting attended.  The Company also pays
reasonable out-of-pocket expenses incurred by non-employee directors to attend
Board of Directors and committee meetings.  Non-employee directors also are
entitled to receive options pursuant to the 1996 Non-Employee Director Stock
Plan (the "1996 Director Plan").  Under the 1996 Director Plan, an aggregate of
100,000 shares of Class A Common Stock have been reserved for grant of options
to purchase Class A Common Stock.  To date, options to acquire 10,000 shares of
Class A Common Stock at an exercise price equal to the fair market value of the
Class A Common Stock on the date of grant have been granted to each of Messrs.
Duroc-Danner and Kite pursuant to the 1996 Director Plan.  In addition, under
such plan, options to acquire 10,000 shares automatically will be granted after
each annual meeting of stockholders to each non-employee director who served as
a director during the preceding six months and who will continue to serve as a
director.

         Effective April 23, 1997, the Board of Directors granted to each of
the Company's non-employee directors, Messrs. Duroc-Danner and Kite additional
options to purchase 10,000 shares of Class A Common Stock at an exercise price
equal to the fair market value on the date of grant.

1996 KEY EMPLOYEE STOCK PLAN

         The Company has established the 1996 Plan pursuant to which incentive
and non-qualified options to purchase shares of Class A Common Stock and awards
of restricted shares of Class A Common Stock will be available for future
grants.  The 1996 Plan is designed to provide certain key employees, including
officers and employee-directors of the Company, with additional incentives to
promote the success of the Company's business and to enhance the Company's
ability to attract and retain the services of qualified persons.  Under the
Plan, options to purchase Class A Common Stock and restricted stock awards up
to an aggregate of 900,000 shares of Class A Common Stock may be granted by the
Committee.  In the event options or restricted stock granted under the 1996
Plan or unvested restricted stock grants expire or terminate or are
surrendered, the unexercised portion thereof may again be available for award
under the 1996 Plan.  As of July 30, 1997, only 1,871 additional shares were
available for grant under the 1996 Plan.

401(k) PLAN

         The Company's employees are eligible to participate in a defined
contribution retirement plan that complies with Section 401(k) of the Code.
Pursuant to such plan, the Company provides matching contributions up to 50% of
the employee's contribution up to 6% of the employee's compensation.

EMPLOYMENT CONTRACTS WITH EXECUTIVE OFFICERS

         Each of the Senior Executive Officers has entered into an employment
agreement (collectively, the "Executive Employment Agreements") with the
Company.  Each of the Executive Employment Agreements has an initial term
through December 31, 1999, except the Executive Employment Agreement with Mr.
Sutton which has an initial term through April 30, 1999.  The Executive
Employment Agreements provide for a minimum annual salary during the term of
the Executive Employment Agreements of approximately $100,000, $280,000,
$228,000 and $180,000 for Messrs. Lawrence, Farr, Sutton and Tighe,
respectively.  The Executive Employment Agreements also provide for certain
automobile allowances, employee benefits, vacation and reimbursement of
expenses.

         The Executive Employment Agreements may be terminated by the Company
with or without





                                      -8-

cause (as hereinafter defined) or by the Executive Officer at any time for any
reason.

         If the Company terminates the Executive Employment Agreement for any
reason other than for "cause" and such termination is not within one year of a
change in control (as defined in the Executive Employment Agreements), the
Company is required to pay to the Executive Officer an amount equal to (i) the
greater of (x) his total base salary for the remainder of the employment period
(as defined in the Executive Employment Agreement) or (y) one month of base
salary for each full year of service completed with the Company as of the date
of termination (or in the case of Mr.  Lawrence, three months of his base
salary, if greater) and with the exception of Mr. Lawrence, (ii) to pay an
amount equal to the Senior Executive Officer's most recent annual bonus and
(iii) to cause the Senior Executive Officer to become fully vested in any stock
options and stock grants held by him.  If the Company terminates the Executive
Employment Agreement for any reason other than for "cause" and such termination
occurs within one year of a change in control, or if the Executive Officer
terminates the Agreement for good cause (as defined in the Executive Employment
Agreement) and such termination occurs within one year of a change in control,
the Company is required to pay to the Executive Officer an amount equal to the
greater of (i) his total base salary for the remainder of the employment
period; (ii) two times the greater of (a) his annualized base salary in effect
upon the occurrence of the change in control or (b) his annualized base salary
in effect on the date notice of termination is received; or (iii) one month of
base salary for each full year of service completed with the Company as of the
date of termination and with the exception of Mr. Lawrence, (A) to pay to the
Senior Executive Officer an amount equal to two times his most recent annual
bonus and (B) to cause the Senior Executive Officer to become fully vested in
any stock options and stock grants held by him.

         Each of Messrs. Farr, Sutton and Tighe has agreed that for the term of
his Executive Employment Agreement and (i) perpetually after termination for
whatever reason, he will not, directly or indirectly, disclose confidential
information; (ii) for a period of two years (one year for Mr. Tighe) following
termination for whatever reason, he will not participate in any business in any
geographic region in which the Company conducts business that is in competition
with the Company or employ any of the Company's employees, induce any of the
Company's employees to leave their employment or in any way interfere with the
employee relations of the Company; and (iii) will disclose and assign to the
Company all inventions developed by him.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         Compensation levels for the Company's executive officers prior to the
IPO in August 1996 were established by the Company's Board of Directors.  The
Board of Directors at the time of the IPO also established the salary levels
set forth in the Company's employment agreements with its executive officers,
including the Company's Chief Executive Officer, as well as the restricted
stock and stock options awards granted at the time of the IPO.  Members of the
Board of Directors at such time consisted entirely of executive officers of the
Company, including the Company's Chairman of the Board, Chief Executive
Officer, General Counsel and Chief Financial Officer (collectively, the "Senior
Executive Officers").

         Following the IPO, compensation relating to the Senior Executive
Officers has been set by the Compensation Committee, except with respect to
compensation levels previously set forth in employment agreements executed in
connection with the IPO, while compensation with respect to other officers of
the Company has been set by the Company's Executive Committee, whose members
consist of Messrs. Farr, Sutton and Tighe.   The Compensation Committee also
has administered the 1996 Plan following the initial public offering.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

PRINCIPAL STOCKHOLDER

         Prior to the IPO, the Company funded certain of its working capital
requirements through advances from Lawrence, which had been evidenced by a note
to Lawrence.  The Company repaid the full amount of principal and accrued
interest on such note with $1.6 million of the net proceeds from the IPO.  In
addition, on June 27, 1996, Dailey declared and paid a dividend in the form of
a $10.0 million promissory note to Dailey's then sole stockholder, a subsidiary
of Lawrence.  On August 13, 1996, such stockholder contributed $5.0 million of
the outstanding principal amount of such note to the capital of the Company.
The remaining $5.0 million principal plus accrued interest was repaid utilizing
a portion of the net proceeds from the IPO.

         Lease Agreements.  The Company maintains executive offices in a
building located in Conroe, Texas and occupies four adjacent manufacturing and
maintenance research and development, and storage facilities, all of which are
owned by Lawrence.  During fiscal 1997, the Company incurred rent expense of
$915,000, respectively, relating to such properties.  Prior to completion of
the IPO, Dailey entered into a new lease agreement with Lawrence relating to
the executive office building and a separate lease agreement relating to the
adjacent facilities.  The rental rates under these new lease agreements were
determined by the Company and Lawrence based upon a survey of rental rates
prepared by an independent firm.  Based upon this survey, the Company believes
that the rental rates and other terms under these lease agreements are
comparable to those that would be obtained in an arm's-length transaction with
an independent third party.

         The Office Lease Agreement is for a five-year term effective as of May
1996, and covers all of the 64,368 square feet of office space in the Conroe
building, as well as the use of access roads and an adjacent outdoor parking
lot.  Rent is payable monthly at the rate of $48,276 per month for the first
two years of the lease, $51,226 per month for the third year, $52,781 per month
for the fourth year and $54,390 per month for the fifth year.

         The Service Center Lease Agreement is for a five-year term effective
as of May 1996.  This lease covers the combined square feet of the district
facility building, 31,316 square feet; the manufacturing building, 31,373
square feet; the open storage building, 17,000 square feet and the separator
building, 1,530 square feet.  The use of access roads and immediately
surrounding grounds is also included.  Rent is $28,000 per month for all four
buildings in the aggregate.

         Relationship Agreement.  Under the terms of a relationship agreement
between the Company and Lawrence (the "Relationship Agreement"), the Company
has agreed to provide to Lawrence and its affiliates, upon their request and on
an as-available basis, various administrative and management services including
cash management, accounting, tax, data processing, human resources and legal
services.  Lawrence pays for such services at rates calculated to recover the
Company's reasonable costs of providing such services.  The Relationship
Agreement also provides that Lawrence will render to the Company technical
consulting services when requested by the Company.  In return, the Company will
pay Lawrence approximately $250,000 per year for the term of the Relationship
Agreement.  The Relationship Agreement commenced upon the closing of the IPO in
August 1996 and terminates on April 30, 1999.  In addition, under the
Relationship Agreement, Lawrence and the Company have agreed to reimburse each
