Note 1:

Summary of Accounting Policies:

The financial information enclosed herewith as at March 31, 1998
and for the three months ended March 31, 1997 is unaudited, and, in
the opinion of the Company, reflects all adjustments (which
included only normal recurring accruals) necessary for a fair
presentation of the financial position as of March 31, 1998, the
changes in cash flow for the three months ended March 31, 1998 and
1997 and the results of operation for these periods.

This quarterly report should be read in conjunction with the
Company's 1997 Annual Report and the March 31, 1998 Management's
Discussion and Analysis of Financial Condition and Results of
Operations.
 

Note 2: 

Results of Operations:

The results of operations for the three months ended March 31, 1998
are not necessarily indicative of the results to be expected for
the full year.

 
Note 3:

Financial Condition and Results of Operation:

As shown in the accompanying consolidated financial statements, the
Company has earned net income for the quarters March 31, 1998 and
1997, respectively, from operations. 

On September 12, 1996, the Company and Summit Bank, (the "Bank")
entered into a Loan and Security Agreement ("Term Note") for a
$300,000 renewable working capital line of credit expiring May 31,
1997. At April 23, 1997 the Term Note was renewed until May 31,
1998, and increased to the amount of $750,000. The Bank was granted
a security interest in substantially all the Company's assets. As
at December 31, 1997, the Company had borrowed $750,000 under the
Term Note. On November 5, 1997 the Bank notified the Company that
covenants under the Credit Agreement to maintain certain levels of
debt to tangible net worth and current assets to current
liabilities were not met on the Company's financial statements.
Payments of interest are being met in accordance with the terms of
the Note. The Bank has not made a demand for the principal amount
of the Term Note. The Bank has made it known that it will not renew
the Term Note on May 31, 1998. The Company is actively pursuing
available alternate financing sources; however, there is no
assurance that alternate sources can be found. If the Term Note is
not replaced, this would have a material adverse effect that may
cause insolvency proceedings.

On September 12, 1996, the Company and Summit Bank, (the "Bank")
entered into a Loan and Security Agreement ("Term Note") for a
$300,000 renewable working capital line of credit expiring May 31,
1997. At April 23, 1997 the Term Note was renewed until May 31,
1998, and increased to the amount of $750,000. The Bank was granted
a security interest in substantially all the Company's assets. As
at December 31, 1997, the Company had borrowed $750,000 under the
Term Note. On November 5, 1997 the Bank notified the Company that
covenants under the Credit Agreement to maintain certain levels of
debt to tangible net worth and current assets to current
liabilities were not met on the Company's financial statements.
Payments of interest are being met in accordance with the terms of
the Note. The Bank has not made a demand for the principal amount
of the Term Note. The Bank has made it known that it will not renew
the Term Note on May 31, 1998. The Company is actively pursuing
available alternate financing sources; however, there is no
assurance that alternate sources can be found. If the Term Note is
not replaced, this would have a material adverse effect that may
cause insolvency proceedings.

Long-term debt consists of the following at March 31,

No new capital leases were entered into for equipment during the
first quarter of 1998.

The Company formerly had employees who were members of a union and
contributed to multi-employer pension plan for such employees in
accordance with a collective bargaining agreement based on monthly
hours worked. Due to the cessation of manufacturing operations at
the Company's Union Facility, the Company ceased being a
participant in the multi-employer pension plan in February 1993. 
Under the Multi-Employer Pension Plan Amendments Act of 1980, the
Company may, under certain circumstances, become subject to
liabilities in excess of contributions made under its collective
bargaining agreement.

The Company received a demand from the Sheet Metal Workers'
National Pension Fund (the "Fund") for payment of a withdrawal
liability in quarterly installments of $502,665 plus interest on
overdue installments, statutory liquidated damages, attorneys' fees
and injunctive relief.

The Company negotiated with the Fund the amount of the liability
and an installment payment schedule.  

On September 6, 1996, the Company agreed to a settlement of the
matter proposed by the Fund and it executed a Settlement
Agreement(the "Agreement"). Among other matters, the Agreement
provides that the Company shall pay the Fund $720,090 (the "Settled
Amount") on account of the withdrawal liability, statutory interest
and counsel fees; provided, however, that if the Company pays to
the Fund the amount of $397,330 principal, plus interest of
$74,455, totaling $471,785 -- $75,000 upon signing and sixty (60)
monthly payments of $6,613.09 commencing October 1, 1996 -- the
Fund would accept the total of $471,785 in satisfaction of the
total withdrawal liability.  

The Agreement contains various representations and warranties by
the Company.  In the event that timely payments are not made or the
Company otherwise defaults under the Agreement, the Settled Amount
will be due the Fund, less any payments received. The Company has
made all payments to the Fund when they are due, and continues to
do so.  

The Company had reserved on its balance sheet as at December 31,
1995, the sum of $581,835 for the withdrawal liability to the Fund.
The Company will charge all the payments made to the Fund to this
reserve account; and if all payments are made in accordance with
the provisions of the Agreement, any balance in the reserve will be
recognized as forgiveness of indebtedness when payments are
complete. At March 31, 1998, the reserve approximated $347,000.


Note 8:

Net Revenue:

Product and product-related net revenue includes revenue from the
Company's manufacturing operation, sales of reconditioned equipment
and rental income. Service revenue includes revenue from the
servicing and installation of equipment. Parts revenue includes
revenue from the sale of replacement and spare parts for equipment
previously manufactured by the Company, as well as equipment
currently being manufactured under the "Tenney" name and
competitors' equipment.
  

Note 9:

Income taxes:
     
The Company accounts for income taxes in accordance with the
Statement of Financial Accounting Standards ("SFAS No. 109"),
"Accounting for Income Taxes," which requires an asset and
liability approach to financial accounting and reporting for income
taxes. Deferred income tax assets and liabilities are computed
annually for differences between the financial statement and income
tax bases of assets and liabilities that will result in taxable or
deductible amounts in the future based on enacted tax laws and
rates applicable to the periods in which the differences are
expected to affect taxable income. Valuation allowances are
established when necessary to reduce deferred tax assets to the
amount expected to be realized. Income tax expense is the tax
payable or refundable for the period plus or minus the change
during the period in deferred tax assets and liabilities. 

A reconciliation of the Company's income tax provision that would
be provided based on a statutory federal income tax rate of 34% to
the Company's effective rate is as follows:

          Net income tax (benefit)       $   0        $ ( 3)


     Deferred income taxes are provided for temporary differences
between the financial reporting and income tax basis of the
Company's assets and liabilities. Temporary differences, net
operating loss carryforwards and valuation allowances comprising
the net deferred taxes on the balance sheet at March 31, 1998, are
as follows:

                                             (In Thousands
                                               of Dollars)

             Deferred tax assets:
               Inventory reserve                $    52 
               Accounts receivable reserve           10
               Deferred revenue                      75
               Deferred compensation                 24
               Deferred pension obligation           12
               Tax loss carryforward              1,557 

                 Total deferred tax assets        1,730

             Deferred tax liabilities:
               Depreciation                         (10)

               Valuation allowance               (1,440)

             Total net deferred tax assets      $   280

     The ultimate realization of the deferred tax asset depends on
the Company's ability to generate sufficient taxable income in the
future.

     At March 31, 1998, the Company has available income tax net
operating loss carryforwards of approximately $4,570,000, which
expire through 2009.

Note 10:

Common stock:

On March 11, 1997 the Board of Directors resolved to amend the
Certificate of Incorporation to provide that Common Stock, $0.01
par value, be issued in two series, denominated Series A and Series
B, both series having the same rights, powers and privileges,
except that Series A has ten (10) votes per share.

The Board also resolved that all issued shares of Common Stock on
April 10, 1997 be classified as Series B Common Stock, $0.01 par
value.

In addition the Board resolved that a stock distribution of one (1)
share of Series A Common Stock, $0.01 par value, be distributed for
each share of Series B Common Stock owned by shareholders of record
on April 10, 1997. The distribution was paid on May 27, 1997.  

This transaction was accounted for as a stock split.

Outstanding options were adjusted effective the close of business
April 10, 1997, so that Optionees have the right to buy a unit
consisting of one share of Series A Common Stock and one share of
Series B Common Stock for each share of Common Stock to which the
option relates at a price per unit equal to the price per share of
Common Stock specified in the outstanding option. The 1995
Incentive Stock Option Plan was amended to relate to an additional
330,000 shares of Series A Common Stock.

On May 26, 1995, at the annual meeting, a new ten-year incentive
stock option plan for officers and key employees was approved and
adopted relating to 400,000 share of Common Stock. The plan
provided that options could be granted from time to time at a price
of not less than 100% of the fair market value of the Common Stock
as of the date of grant for officers and employees who own less
than 10% of the voting stock of the Company and 110% of fair market
value for those officers and employees who own more than 10% of the
voting stock (affiliate employees). Options granted are exercisable
immediately and terminate no later than ten years from date of
grant (five years from date of grant for affiliate employees). 

The fair value of each option granted is estimated on the grant
date using the Black-Scholes model. The following assumptions were
made in estimating fair value:

          Assumption                    1995 Plan
          Dividend Yield                      0%
          Risk-free Interest Rate          7.50%
          Expected Life                  3 Years
          Expected Volatility             24.89%

The Company applies APB Option 25 in accounting for its stock
compensation plan. Accordingly, no compensation cost has been
recognized for the 1995 Plan in 1998 or 1997. Had compensation cost
been determined on the basis of fair value pursuant to FASB
Statement No. 123, net income and earnings per share would have
been reduced as follows:

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

As shown in the accompanying consolidated financial statements, the
Company has earned net income for the quarters March 31, 1998 and
1997, respectively, from operations. 

On September 12, 1996, the Company and Summit Bank, (the "Bank")
entered into a Loan and Security Agreement ("Term Note") for a
$300,000 renewable working capital line of credit expiring May 31,
1997. At April 23, 1997 the Term Note was renewed until May 31,
1998, and increased to the amount of $750,000. The Bank was granted
a security interest in substantially all the Company's assets. As
at December 31, 1997, the Company had borrowed $750,000 under the
Term Note. On November 5, 1997 the Bank notified the Company that
covenants under the Credit Agreement to maintain certain levels of
debt to tangible net worth and current assets to current
liabilities were not met on the Company's financial statements.
Payments of interest are being met in accordance with the terms of
the Note. The Bank has not made a demand for the principal amount
of the Term Note. The Bank has made it known that it will not renew
the Term Note on May 31, 1998. The Company is actively pursuing
available alternate financing sources; however, there is no
assurance that alternate sources can be found. If the Term Note is
not replaced, this would have a material adverse effect that may
cause insolvency proceedings.

At March 31, 1998, the Company's cash and cash equivalents totaled
$80,000, an addition of $33,000 from the balance of $47,000 as at
December 31, 1997. Net cash provided by operations  totaled
$74,000. Cash was provided primarily by the increased collection
effort reducing the amount of outstanding receivables of $157,000.
The primary use of cash amounting to $212,000 was due to the
reduction of billings in excess of estimated revenue.

The Company is engaged in one industry segment: the engineering,
marketing and manufacturing of diversified high-technology vacuum
systems for space simulation, optic coating and sputtering; and
provides service, refurbishing, upgrading, installation and sale or
rental of reconditioned test equipment. 


RESULTS OF OPERATIONS

Total net revenue for the three months ended March 31, 1998, of 
$2,153,000 compares to net revenue of $2,321,000 in the
corresponding 1997 period.

Product and product-related net revenue for 1998 and 1997 was
$1,731,000 and $1,983,000, respectively. The decrease was due to
lower sales in the DynaVac subsidiary. 

Service-related revenue of $293,000 for the three months ended
March 31, 1998, compares to the first quarter 1997 revenue of
$213,000, an increase of 38%. The increase is due primarily to
larger numbers of upgrades and retrofits of Tenney equipment.

Revenue related to the sale of parts totaled $129,000 and $125,000
for the quarters ended March 31, 1998 and 1997, respectively.

The Company's order backlog at March 31, 1998, December 31, 1997,
and March 31, 1997 was approximately $1,800,000, $2,200,000 and
$888,000, respectively. The increase is due primarily to an
increase in receiving large contract sales at the Company's DynaVac
subsidiary.

The total cost of sales as a percentage of net revenue was 77% for
the quarter ended March 31, 1998, and compares to 75% for the
corresponding 1997 period. 

The first quarter 1998 cost of sales percentage of product and
product-related sales was 82% and compares to a cost of sales of 
77% during 1997. The increase is due to a higher amount of labor
costs in January and February at the DynaVac subsidiary. 

Service cost of sales as a percentage of sales was 46% and 70% for
the 1998 and 1997 quarters, respectively. The decrease is due to
lower overhead costs and more favorable product mix.

Cost of sales as a percentage of sales during 1998 for parts was
74% and compares to 54% for the 1997 corresponding period. The
increase was due to the sales mix of parts.

Selling and administrative expenses for the first quarter of 1998
was $444,000 and compares to expenses of $526,000 in the 1997
period. The decrease is due to cost containment reductions made in

$4,000 in the 1997 period.
