COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT

         Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's officers and directors, and persons who beneficially own more than 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 shareholders are
required by the regulations promulgated under Section 16(a) to furnish the
Company with copies of all Section 16(a) forms they file.

      Based solely on its review of the copies of such forms received by it, or
written representations from certain reporting persons that no Forms 5 were
required for those persons, the Company believes that, during the period from
January 1, 1998 through December 31, 1998, all filing requirements applicable to
officers, directors and greater than ten-percent shareholders were complied
with, except that John W. Sinders reported his appointment to the Board of
Directors and the purchase of 40,000 shares of Class A Common Stock on Form 5,
rather than on Form 3 and Form 4.

         insurance. Amounts in 1998 for Mr. Farr also include severance payments

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

PRINCIPAL STOCKHOLDER

         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. In 1998, the Company incurred rent expense of $941,000
relating to such properties. 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 International Inc. (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 1996 IPO and terminates on April 30, 1999. In addition, under the
Relationship Agreement, Lawrence and the Company have agreed to reimburse each
other for the costs of certain insurance policies purchased by one party on
behalf of the other. As of December 31, 1998, Lawrence owed the Company
approximately $362,000, for products and services rendered pursuant to the
Relationship Agreement.

         Registration Rights Agreement. Pursuant to the terms of a registration
rights agreement with Mr. Lawrence (the "Lawrence Registration Rights
Agreement"), upon the request of Mr. Lawrence (or certain assignees) for a
period of ten years (beginning in 1996), the Company has agreed to register, on
up to two occasions, the sale of a minimum of 500,000 shares and up to all
5,000,000 shares of Class B Common Stock beneficially owned by Mr. Lawrence that
Mr. Lawrence (or such assignees) requests to be registered under the Securities
Act and applicable state securities laws. The Company will become obligated to
register the sale of the Class B Common Stock on one additional occasion if Mr.
Lawrence dies during the term of the Lawrence Registration Rights Agreement and
Mr. Lawrence previously has exhausted its two demand registrations. The Company
also is obligated to offer Mr. Lawrence and certain assignees the right to
include shares of the Class B Common Stock owned by it in certain registration
statements filed by the Company. The Company is obligated to pay all expenses
incidental to such registrations, excluding fees of counsel to Mr. Lawrence,
underwriters' discounts and commissions, and transfer fees.

         During 1998, the Company paid an aggregate of $167,000 to relatives of,
and entities controlled by, the company's Chairman of the Board relating to
miscellaneous goods and services.

OTHER

         In January 1997, the Company loaned Mr. Farr $250,000 pursuant to a
five-year promissory note. Interest accrues at the prime rate and is payable
monthly by Mr. Farr. The note is secured by a pledge of 36,000 shares of Class A
Common Stock held by Mr. Farr. In connection with Mr. Farr's leaving the
Company's employment, the promissory note was repaid.

         In August 1997, John W. Sinders, Jr., and Executive Vice President of
Jefferies, accepted his appointment as a non-voting advisory director of the
Board of Directors of the Company. In June 1998, Mr. Sinders became a director
of the Company. He subsequently resigned in February 1999. Jefferies has
provided investment banking services to the Company in the past, including
serving as lead underwriter in the Company's initial public offering and as the
initial purchaser in the sale and issuance of $115 million principal amount of
the Company's 9?% Senior Notes due 2007 (the "Old Notes") in August 1997, for
which Jefferies has received usual and customary fees. In February 1998,
Jefferies sold the Old Notes to the Company contemporaneously with the closing
of the issuance of the Company's 9?% Senior Notes due 2008 (the "Outstanding
Notes") at an aggregate price of 111% of their principal amount, plus accrued
and unpaid interest up to, but not including, the date of payment. Jefferies
also acted as the initial purchaser in the sale of the Outstanding Notes, for
which it received usual and customary fees. Pursuant to a letter agreement
between the Company and Jefferies, Jefferies has acted as a financial advisor to
the Company in connection with the acquisition of, merger or other combination
with certain potential acquisition targets. Except for usual and customary fees
paid in connection with the acquisitions of Directional Wireline Services, Inc.,
DAMCO Services, Inc. and DAMCO Tong Services, Inc. and $1.0 million in
connection with other financial advisory services, the Company has not paid
Jefferies and is not obligated to pay Jefferies any compensation for services
rendered under this agreement or otherwise to date.
