                                 (UNAUDITED)


(1)  GENERAL

     The consolidated financial statements included herein have been prepared 
by the Company, without audit, pursuant to the rules and regulations of the 
Securities and Exchange Commission. The financial statements reflect all 
adjustments (consisting of normal recurring accruals) which are, in the 
opinion of management, necessary to fairly present such information. Although 
the Company believes that the disclosures are adequate to make the 
information presented not misleading, certain information and footnote 
disclosures, including significant accounting policies, normally included in 
financial statements prepared in accordance with generally accepted 
accounting principles have been omitted pursuant to such rules and 
regulations. It is suggested that these financial statements be read in 
conjunction with the consolidated financial statements and the notes thereto, 
as well as Item 7. - "Management's Discussion and Analysis of Results of 
Operations and Financial Condition," included in the Company's annual report 
on Form 10-K filed for the year ended May 31, 1996.

(2)  INVENTORIES

(3)  STATEMENTS OF CASH FLOWS

     The Company considers all highly liquid investments purchased with an 
original maturity of three months or less to be cash equivalents.  The 
Company does not invest or intend to invest in derivative securities.  
Similar investments with original maturities beyond three months are 
considered short-term investments available for sale or carried at market. 
Exchange rate fluctuations have not had a material effect on the Company's 
Statements of Cash Flows.

     Supplemental disclosures of cash flow information for the three months

(4)  LONG TERM DEBT

     In August 1996, the Company, through one of its wholly-owned 
subsidiaries, obtained a $12.6 million, ten-year term loan secured by certain 
of its land and buildings located in Stafford, Texas which includes the 
Company's executive offices, research and development headquarters, and 
newly-constructed electronics manufacturing building.  The term loan, which 
the Company has guaranteed under a Limited Guaranty, bears interest at a 
fixed rate of 7.875% per annum.  The Company leases all of the property from 
its subsidiary under a master lease, which lease has been collaterally 
assigned to the lender as security for the term loan.  The term loan provides 
for penalties for prepayment prior to maturity.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS 
          AND FINANCIAL CONDITION

RESULTS OF OPERATIONS

     NET SALES AND OTHER REVENUES.  The Company's first quarter net sales and 
other revenues increased by $18.2 million, or 33.3%, to $73.0 million 
compared to the prior year's first quarter. The increase in sales revenue was 
primarily due to the sale of six I/O SYSTEM TWO MRX and three RSR systems to 
geophysical contractors in Canada, Russia, Ukraine, Venezuela and the United 
States. In addition, there were sales of over 400 marine I/O SYSTEM TWO MSX 
streamers and energy sources during the first quarter. The prior year's first 
quarter net sales and other revenues principally consisted of six system 
sales to geophysical contractors in Russia and the first I/O SYSTEM TWO RSR 
system, as well as the contribution of $20.1 million in sales of products 
from the Western Exploration Products Group (WGEP) product lines acquired by 
the Company in June 1995 from Western Atlas, Inc. (the "WGEP Acquisition"). 
The Company's results for the three-month period ended August 31, 1996 
reflect a full quarter's operations giving effect to the WGEP Acquisition, 
while the results for the quarter ended August 31, 1995 reflect only two 
months of such combined operations.

     GROSS PROFIT MARGIN.  The Company's first quarter gross profit margins 
were adversely affected by changes in the sales mix and sales of lower margin 
products from product lines acquired in the WGEP Acquisition. First quarter 
profit margins declined from 40.0% for the prior fiscal year's first quarter 
to 39.2%.

     OPERATING EXPENSES.  Operating expenses increased $3.6 million or 29.2%, 
for the first quarter over the prior year's first quarter operating expenses. 
Research and development expenses increased $1.3 million, or 29.0%, primarily 
due to increased personnel and related costs resulting from the WGEP 
Acquisition. Marketing and sales expenses increased $205,000, or 6.6% 
primarily due to increased personnel and related costs resulting from the 
WGEP Acquisition, and increased advertising expenses offset by decreased 
third party commissions. General and administrative expenses increased $1.7 
million, or 41.2%, primarily due to increased non-recurring professional 
fees, increases in state and local taxes derived from increased levels of 
property and assets resulting from the WGEP Acquisition, increased data 
processing expenses, and increased depreciation expense. Amortization of 
identified intangibles increased $414,000 or 59.7%, primarily due to goodwill 
resulting from the WGEP Acquisition.

     INTEREST EXPENSE.  Interest expense for the first quarter of fiscal 1997 
was nil and $868,000 for the first quarter of fiscal 1996 primarily due to 
interest on the $70 million term indebtedness incurred in June 1995 in 
connection with the WGEP Acquisition.  These borrowings were repaid in 
November 1995.

     INCOME TAX EXPENSE.  The Company's effective income tax rate was 
approximately 32%, both for the first quarter of fiscal 1997 and the first 
quarter of fiscal 1996.










                                      8 


LIQUIDITY AND CAPITAL RESOURCES

     The Company has financed its operations from internally generated cash 
flow, its credit facilities, and funds from equity financings. Cash flows 
from operating activities before changes in working capital items were a 
positive $13.6 million for the three months ended August 31, 1996. However, 
cash flows from operating activities after changes in working capital items 
were a negative $26.0 million for the three months ended August 31, 1996 
primarily due to increases in trade accounts, notes receivable and inventory 
required to support increased sales levels, along with a decrease in accounts 
payable. The Company believes that it has sufficient credit facilities in 
place to finance these increases in its working capital requirements.  As of 
August 31, 1996 the Company has no borrowings outstanding under its revolving 
line of credit.

     As of August 31, 1996, total trade notes receivable had increased $22.8 
million over the corresponding amount outstanding at May 31, 1996, reflecting 
the increased levels of Company-financed sales during the first three months 
of fiscal 1997. The Company expects that these increased levels of 
Company-financed sales will continue for the foreseeable future.  For 
information concerning the Company's sales finance activities, see "Item 1. - 
Business-Markets and Customers" of the Company's Annual Report on Form 10-K 
for the year ended May 31, 1996.

     In August 1996, a subsidiary of the Company borrowed $12,550,000 in 
long-term financing secured by the land, buildings and improvements housing 
the Company's executive offices, research and development headquarters and 
new manufacturing facility in Stafford, Texas.  The loan bears interest at 
the rate of 7.875% per annum and is repayable in equal monthly installments 
of principal and interest of $151,439.  The promissory note, which matures on 
September 1, 2006, contains prepayment penalties.  See Note (4) - Long-Term 
Debt of the Notes to Consolidated Financial Statements.

     The Company anticipates expenditures for the current fiscal year for 
exploration and development of oil and gas properties to be approximately $6 
million and expects to fund this level of expenditures through cash flows 
from operations. Actual levels of exploration and development expenditures 
may vary significantly due to many factors, including oil and gas prices, 
industry conditions, and the success of the Company's exploration and 
development projects. The Company's exploration and development projects are 
operated by third parties which control the timing and amount of expenditures 
required to exploit the participant's interests in these prospects. The 
Company expects to participate in the drilling and completion of six wells in 
fiscal 1997. The Company's participation in oil and gas activities is 
accounted for on a full cost basis.

     Capital expenditures for property, plant, and equipment totaled $10.2 
million for fiscal 1996 and $6.4 million for the first three months of fiscal 
1997, and are expected to aggregate $26.5 million for fiscal 1997. As noted 
above, the Company concluded in August 1996 a long-term credit facility of 
$12.6 million to assist in financing the costs of land and improvements in 
Stafford, Texas. The Company believes that the combination of its existing 
working capital, unused credit available under its working capital credit 
facility, internally generated cash flow and access to other financing 
sources will be adequate to meet its anticipated capital and liquidity 
requirements for the foreseeable future.
