Tech-Sym Corporation

Notes to Consolidated Financial Statements

     1.  The accompanying unaudited consolidated financial statements of
     Tech-Sym Corporation and its subsidiaries (the "Company") have been
     prepared in accordance with the instructions to Form 10-Q.  Accordingly,
     they do not include all of the information and footnotes required by
     generally accepted accounting principles for complete financial
     statements and should be read in conjunction with the financial
     statements and notes thereto appearing in the Company's Annual Report
     for the year ended December 31, 1996.

     In the opinion of the Company's management ("Management"), all
     adjustments necessary for a fair presentation of the results of
     operations for all periods reported have been included.  Such
     adjustments consist only of normal recurring items.

     The consolidated statements of income for the three and six months ended
     June 30, 1997, are not necessarily indicative of the results to be
     expected for the full year ending December 31, 1997.

     The consolidated financial statements have been restated to reflect the
     geoscientific software subsidiary of the Company's majority owned
     subsidiary, GeoScience Corporation ("GeoScience"), as a discontinued
     operation in accordance with Accounting Principles Board Opinion No. 30
     (see Note 2).

     The accompanying consolidated financial statements for the quarter and
     six months ended June 30, 1997, have been restated.  The restatement
     reflects the higher cost of revenue for certain engineering and
     manufacturing costs which were erroneously capitalized at the Company's
     majority-owned GeoScience subsidiary.  The restatement also corrects an
     overstatement in sales and earnings at the Company's TRAK Microwave
     subsidiary that resulted from errors associated with manual inputs made
     into a new management information system.  The restated consolidated
     statement of income and accumulated earnings for the quarter and six
     months ended June 30, 1997, are summarized as follows (in thousands,
     except per share amounts):

2.   Effective June 30, 1997 (the "measurement date"), GeoScience adopted a plan
     to sell its geoscientific software subsidiary, CogniSeis Development, Inc.
     ("CogniSeis"). Accordingly, CogniSeis is reported as a discontinued
     operation for the periods presented. Management anticipates CogniSeis will
     incur operating losses approximating $500,000 from the measurement date
     through the disposal date. Such losses have been deferred due to the fact
     that Management expects a gain on the sale of CogniSeis.

     On July 15, 1997, GeoScience signed a letter of intent to sell CogniSeis
     for cash and guaranteed future royalties with a combined estimated value
     between $19.5 and $23 million. The proposed sale is subject to the terms of
     a negotiated

     definitive agreement which could vary from the letter of intent, and no
     assurances can be made that this transaction will be completed.
     Management's current estimate indicates that the total sale proceeds
     from the disposal of CogniSeis will result in a gain on the
     transaction.  However, the ultimate financial impact of the negotiated
     definitive agreement could differ from Management's current estimate.

     The operating results (unaudited) of the discontinued operation are

     EARNINGS PER SHARE was issued. FAS 128 is effective for earnings per share
     calculations for periods ending after December 15, 1997. At that time, the
     Company will be required to change the method currently used to compute
     earnings per share and to restate all prior periods. Adoption of FAS 128 is
     not expected to have a material effect on the Company's financial position
     or operational results.

Item 2. Management's Discussion and Analysis of Financial
Condition and Results of Operations


RESULTS OF OPERATIONS

In June 1997, the Company's majority owned subsidiary, GeoScience Corporation
("GeoScience") adopted a plan to sell its geoscientific software subsidiary,
CogniSeis Development, Inc. ("CogniSeis").  CogniSeis is accounted for as a
discontinued operation.  Accordingly, the consolidated financial statements
have been presented to report separately the operating results of the

ENDED JUNE 30, 1996

Revenue increased $6,445,000 or 10% to $72,225,000 for the quarter ended June
30, 1997.  The increase in revenue resulted primarily from increased
shipments in the communications and geoscientific business which increased
from the same quarter in the prior year $7,096,000 and $3,326,000,
respectively.  Within the communications business, shipments of broadcast
equipment, microwave products and weather radar systems demonstrated revenue
growth over the second quarter of 1996.  In the geoscientific business, the
increase primarily resulted from increased shipments of land and ocean bottom
cables.  The increases in the communications and geoscientific business more
than offset the $3,199,000 decrease in revenue in the defense systems
business which was a result of delayed bookings of government and foreign
orders.

The consolidated gross profit margin decreased from 35% to 31% of revenue for
the quarter ended June 30, 1997, compared to the same quarter in the prior
year.  The majority of the decrease in gross profit margin was attributed to
the communications business.  Within the broadcast area of the communications
business, the gross profit margin was negatively impacted by cost over-runs
on several long-term projects and initial start-up costs on a number of new
products.  The gross profit margin of the microwave products' portion of the
communications business suffered due to production labor costs increasing at
a greater rate than the increase in product shipments and due to
inefficiencies and input errors relating to a new management information
system.  Increased material costs on several contracts within the defense
systems business due to supplier problems also contributed to a lower than
customary gross profit margin.  The gross profit margin of the geoscientific
business improved over the second quarter of 1996 primarily as a result of
reduced costs derived from improved manufacturing efficiencies and decreased
electronic

component prices related to the 24-bit seismic data acquisition module that
offset the increased engineering and manufacturing costs associated with
design changes to the 24-bit module and increased manufacturing costs within
the domestic seismic cable manufacturing facility.

Consolidated selling, general and administrative expenses increased 10% to
$16,155,000 during the second quarter of 1997.  These expenses as a
percentage of revenue decreased slightly in comparison to the same quarter a
year ago.  The majority of the $1,432,000 increase occurred within the
geoscientific business.  The increase primarily resulted from additional
costs for support personnel and royalties associated with the overall growth
in the business and additional commissions associated with increased
international sales.  Furthermore, expenses related to managing the
consolidated business and being a publicly traded company were added.  The
Company-sponsored product development expenses were $3,394,000 for the
quarter ended June 30, 1997, compared to $3,561,000 for the quarter ended
June 30, 1996.  The decrease was primarily in the communications business as
a result of the completion of several projects relating to broadcast and
antenna equipment that were under development in the second quarter of 1996.
The overall decreases exceeded the increases incurred within the
geoscientific business due to design changes to the 24-bit seismic data
acquisition module.

Interest expense increased to $1,081,000 during the second quarter of 1997
from $706,000 during the second quarter of 1996 as a result of the increase
in interest bearing debt incurred primarily to support the growth of the
business and, to a lesser extent, to fund the Company's stock buy-back
program.  Other income increased to $1,824,000 from $1,103,000 primarily due
to foreign currency translation gains within the communications business.

The effective tax rate for the quarter ended June 30, 1997 was 30% compared
to 35% for the same period in the prior year.  The Company's effective tax
rate is lower than statutory United States rate due principally to benefits
generated from foreign sales.

Minority interest expense from continuing operations for the quarter ended
June 30, 1997, was $242,000 compared to $246,000 for the quarter ended June
30, 1996.  Minority interest expense reflects the portion of GeoScience
Corporation's net income from continuing operations of $1,111,000 and
$1,365,000 for the quarter ended June 30, 1997 and 1996, respectively, which
is attributable to minority shareholders.

Condition and Results of Operations - Continued

Income from continuing operations before extraordinary item for the second
quarter of 1997 was $2,183,000 compared to $16,983,000 for the corresponding
quarter a year ago.  The results of the second quarter of 1996 included a net
gain of $13,700,000 related to the sale to the public of common shares of
24.7% of GeoScience Corporation.  The lower gross profit margin and higher
operating expenses as discussed above caused the income of continuing
operations for the current quarter to be less than that of the 1996 quarter
without the gain on the sale of GeoScience stock.

Loss from the discontinued operation for the quarter ended June 30, 1997,
decreased $192,000 or $.02 per share from the same quarter in the prior year
as a result of an increase in interest income recognized on contract
installment sales.

Net income for the quarter ended June 30, 1997, decreased 90% to $1,443,000
or $.24 per share compared to net income of $15,016,000 or $2.28 per share
for the same quarter in the prior year.  The 1996 second quarter net income
included a net gain of $13,700,000 resulting from the sale of common shares
of GeoScience Corporation to the public and a net loss of $1,035,000 for the
premium paid on early extinguishment of debt.

RESULTS OF OPERATIONS - SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO JUNE 30,
1996

Revenue increased 10% to $145,123,000 for the six months ended June 30, 1997,
from $131,588,000 for the same period in the prior year.  The increase in
revenue resulted from increased shipments in the communications and
geoscientific business of $10,737,000 and $7,783,000, respectively.  Revenue
relating to the defense systems business decreased $4,032,000 from the same
period in the prior year due to continued delays in the receipt of new
government and foreign orders.  Within the communications business, shipments
in all major product areas (broadcast equipment, microwave products and
weather radar systems) increased over the six months ended June 30, 1996.
Increased shipments of land, ocean bottom and marine seismic cables and
revenue relating to the technical data services provided to oil exploration
and production customers resulted in a 20% growth in the revenue of the
geoscientific business over the same period in the prior year.

The consolidated gross profit margin decreased from 35% to 30% of revenue for
the six months ended June 30, 1997.  The overall decrease is primarily
related to the communications business.

Item 2. Management's Discussion and Analysis of Financial
Condition and Results of Operations - Continued

The reasons for the decrease within the communications business
are essentially the same as those discussed for the quarter, along with a
change in the product mix within the broadcast area.  The gross profit margin
for the geoscientific business decreased from 41% to 39% of revenue for the
six months ended June 30, 1997, compared to the six months ended June 30,
1996.  The decrease was a result of (i) larger shipments of marine seismic
cables, which have higher production costs in relationship to selling price
as compared to the electronics portion of the seismic data acquisition
systems, (ii) increased engineering and manufacturing costs associated with
design changes to the 24-bit seismic data acquisition module and (iii)
increased manufacturing costs within the domestic seismic cable manufacturing
facility.  The gross profit margin as a percent of revenue for the defense
systems business improved from 22% to 24% over the same period in the prior
year.

Consolidated selling, general and administrative expenses increased to
$31,594,000 for the period ended June 30, 1997, from $28,704,000.  These
expenses as a percentage of revenue decreased slightly in comparison to the
same quarter in the prior year.  The increase occurred in the geoscientific
business.  The increase in the geoscientific business resulted from (i) the
growth in support personnel associated with the growth in the business, (ii)
additional royalty costs associated with the overall increase in revenue,
(iii) additional commissions associated with the increased international
sales and (iv) the added costs of managing the consolidated geoscientific
business as a publicly traded company.  Company-sponsored product development
expenses were $6,549,000 for the period ended June 30, 1997 compared to
$7,382,000 for the period ended June 30, 1996.  The decrease occurred
primarily within the broadcast area of the communications business.  The
reasons for the decrease are as discussed in the results for the quarter
ended June 30, 1997.

Interest expense was $1,761,000 for the six month period ended June 30, 1997,
as compared to $2,075,000 for the six month period ended June 30, 1996.  The
decrease was derived from the first three months of the year due to a
reduction in interest bearing debt that occurred in the second quarter of
1996 as a result of proceeds generated from the sale of stock of GeoScience.
Other income increased to $2,133,000 from $1,934,000 primarily due to foreign
currency transaction gains within the communications business that more than
offset the decrease in interest income on interest bearing receivables within
the geoscientific business.

The effective tax rate for the six months ended June 30, 1997 was

31% compared to 34% for the same period in the prior year.  The
Company's effective tax rate is lower than the statutory United States rate
due principally to tax benefits generated from foreign sales.

Minority interest expense from continuing operations for the six months ended
June 30, 1997, was $338,000 compared to $246,000 for the six months ended
June 30, 1996.  Minority interest expense reflects the portion of GeoScience
Corporation's net income from continuing operations of $1,535,000 and
$2,370,000 for the six months ended June 30, 1997 and 1996, respectively,
which is attributable to minority shareholders.

Income from continuing operations before extraordinary item for the six month
period of 1997 was $4,225,000 compared to $19,893,000 for the corresponding
period a year ago.  The six months ended June 30, 1996 included a net gain of
$13,700,000 as discussed in the results for the quarter ended June 30, 1997.
The lower gross profit margin and higher operating expenses as discussed
above caused the income of continuing operations for the current six month
period to be less than that of the comparable 1996 period without the gain on
the sale of GeoScience stock.

Loss from the discontinued operation for the six months ended June 30, 1997
decreased $327,000 from the same period in the prior year as a result of an
increase in interest income recognized on contract installment sales and the
change in minority ownership interest between the two periods.

Net income for the six months ended June 30, 1997, decreased 83% to
$2,989,000 or $.50 per share compared to net income of $17,295,000 or $2.63
per share for the same period in the prior year.  The 1996 results included a
net gain of $13,700,000 on the sale of common shares of GeoScience
Corporation to the public and a net loss of $1,035,000 for the premium paid
on early extinguishment of debt.

Backlog at June 30, 1997 was $122,000,000 compared to $147,000,000 at June
30, 1996.  The decrease occurred primarily in the defense systems business
and the broadcast area within the communications business.  The decrease in
backlog may unfavorably affect the Company's operating results for the third
and fourth quarter if orders are not received in time to ship during the
respective periods.

LIQUIDITY AND CAPITAL RESOURCES

The Company is currently satisfying its working capital and capital
expenditure requirements through internally generated cash from operations
and bank borrowings.  At June 30, 1997, the Company's working capital balance
was $137,095,000 compared to $135,735,000 at December 31, 1996.  The increase
in working capital is a result of a decrease in liabilities which resulted
from segregating the net assets of the discontinued operation as a
non-current asset at June 30, 1997 and an increase in inventory levels.  Cash
used for operations was $15,699,000 for the six months ended June 30, 1997,
compared to cash provided by operations of $7,779,000 for the same period in
the prior year.

As of June 30, 1997, the Company had uncommitted bank lines of credit
aggregating approximately $84,295,000.  Borrowings under these lines were
$38,798,000, including the discontinued operation.  The Company had a working
capital ratio of 2.47 to 1.0 and debt to total capitalization of 29%.  The
Company believes that its current financial position and available lines of
credit will provide ample sources of funds to meet foreseeable requirements.

Purchases of property, plant and equipment totaled $5,965,000 for the six
months ended June 30, 1997, compared to $8,411,000 for the corresponding
prior year period.  The Company estimates that capital expenditures for
property, plant and equipment during the remainder of 1997 will be
approximately $9,830,000.  Most of the anticipated capital expenditures are
not subject to firm commitments and the Company may modify its plans
depending on future results of operations or other factors.
