(1)  The  information contained herein with respect to September 30, 1996 and
     the three and nine months ended September 30, 1996 and 1995, has not been
     audited but was prepared in conformity with the accounting principles and
     policies described in the Company's annual report (Form 10-K) for the year
     ended December 31, 1995.  Included are all adjustments which, in the
     opinion of management, are necessary for a fair presentation of the
     financial information for the three and nine months ended September 30,
     1996 and 1995.  The results of interim periods are not necessarily
     indicative of results to be expected for the year.

(2)  On September 27, 1996, the Company acquired 100% of the issued and
     outstanding capital shares of Seaboard Lloyd Limited (Seaboard), a private
     company incorporated in Scotland under the Companies Acts of the United
     Kingdom in a privately negotiated transaction.

     The business of Seaboard is the manufacture of oilfield equipment. Seaboard
     operates from a facility located in Cumbernauld, Scotland. The Company
     plans to continue to operate Seaboard in substantially the same manner as
     it was operated prior to the acquisition.

     The Company paid a purchase price of $1,580,000 cash for the issued share
     capital of Seaboard. The source of the funds for the purchase was
     approximately $1,080,000 in cash on hand and $500,000 borrowed under the
     Company's existing credit facility. The purchase price was allocated (based
     on preliminary estimates and assumptions) as follows:

(3)  At September 30, 1996, the Company had net operating loss carryforwards
     ("NOL Carryforwards") available to offset future taxable income in the
     approximate amount of $25,830,000.  These amounts expire between the years
     2001 and 2003.  Special limitations exist under the law which may restrict
     utilization of the regular tax and alternative minimum tax NOL
     Carryforwards.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                        

Results of Operations

Industry wide, the average active domestic rig count as reported by Baker Hughes
Incorporated, a leading industry observer was 757 for the nine months ended
September 30, 1996, compared with 709 for the nine months ended September 30,
1995.  The average active rig count is an indicator of the market in which the
Company operates.

The Company's revenues increased by $4,033,000 (43.5%) to $13,304,000 for the
three month period ended September 30, 1996, from $9,271,000 for the three month
period ended September 30, 1995.  In addition, the Company's nine month revenues
increased by $9,235,000 (35.9%) to $34,949,000 for the nine months ended
September 30, 1996, from $25,714,000 for the nine months ended September 30,
1995.  The increase in revenues is principally the result of (i) higher
drilling activity (ii) certain large customers increasing their levels of
activity (iii) an increase in the Company's customer base, and (iv) higher
international volume.

Gross profit for the nine months ended September 30, 1996 increased by
$2,275,000 to $8,025,000, from $5,750,000 for the nine months ended September
30, 1995.  The gross profit percentage was 23.0% for the nine months ended
September 30, 1996, compared with 22.4% for the nine months ended September 30,
1995.   This increase is the result of higher fixed cost utilization and
additional savings on outsourcing of materials.

Selling, general and administrative expenses increased by $1,074,000 to
$6,906,000 for the nine months ended September 30, 1996 from $5,832,000 for the
nine months ended September 30, 1995.  The primary reason for the increase is
due to costs associated with international marketing efforts and additional
sales personnel.  The selling, general and administrative expense, as a
percentage of sales, was 19.8% in the first nine months of 1996 compared with
22.7% for the same period in 1995.

The Company generated operating income of $663,000 and $1,119,000 for the three
and nine months ended September 30, 1996, compared with operating losses of
$144,000 and $82,000 for the three and nine months ended September 30, 1995.
The increase in operating profit is due to increased sales volume with relative
decreases in direct, indirect, selling and administrative costs.

The provision for income taxes for the nine months ended September 30, 1996 and
1995 resulted in a provision of $370,000 for 1996 and a benefit of $93,000 for
1995, respectively.

Liquidity and Capital Resources

On June 6, 1996, the Company entered into an Investment Agreement pursuant to
which John Wood Group PLC purchased and the Company sold an aggregate of
7,384,616 shares of Common Stock at a purchase price of $0.8125 (13/16) per
share (or an aggregate consideration of $6,000,000.50).

On August 6, 1996, the loan facility was amended to extend the line of
credit through June 30, 1997 and the total availability was increased to
$5,000,000.

On September 27, 1996, the Company acquired 100% of the issued and outstanding
capital shares of Seaboard Lloyd Limited ("Seaboard"), a private company
incorporated in Scotland under the Companies Acts of the United Kingdom in a
privately negotiated transaction.

The business of Seaboard is the manufacture of oilfield equipment.  Seaboard
operates from a facility located in Cumbernauld, Scotland.  The Company plans to
continue to operate Seaboard in substantially the same manner as it was operated
prior to the acquisition.

The Company paid a purchase price of $1,580,000 cash for the issued share
capital of Seaboard. The source of the funds for the purchase was approximately
$1,080,000 in cash on hand and $500,000 borrowed under the Company's existing
credit facility.

Pursuant to the Company's long-term debt agreements, approximately $293,000 in
principal payments are due over the next twelve months.  The Company believes
its line of credit facility, combined with cash generated from operations, will
be adequate to fund its operations for at least the next twelve months.

The Company currently anticipates incurring capital expenditures of
approximately $1,000,000 through 1996, principally for machine tools, vehicles
and computer purchases.  The Company expects to fund these expenditures from
cash provided by operations,  additional capital lease obligations and from the
Company's line of credit facility.
