               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Board of Directors
Technical Instrument Company

      We have audited the accompanying balance sheets of Technical Instrument
Company as of December 31, 1994 and 1995, and the related statements of
operations and retained earnings, and cash flows for each of the three years in
the period ended December 31, 1995. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

      We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

      In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Technical Instrument Company
as of December 31, 1994 and 1995, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1995, in
conformity with generally accepted accounting principles.

                          NOTES TO FINANCIAL STATEMENTS

                        December 31, 1993, 1994 and 1995

NOTE A - SUMMARY OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Technical Instrument Company (the Company) designs, manufactures and distributes
microscopes and other precision optical instruments and equipment. The Company
has two divisions: a proprietary products division and a distribution division
(see Note B).

The Company's proprietary products division designs, manufactures and
distributes precision optical equipment used by manufacturers of semiconductors
and other high technology products. The proprietary products division derives
approximately 45% of its revenues from international sales. The Company's
distribution division has an exclusive license to distribute microscopes and
other precision optical instruments in Northern California.

A summary of the Company's significant accounting policies applied in the
preparation of the accompanying financial statements follows:

o     Inventories

      Inventories are stated at the lower of cost (first-in, first-out method)
      or market.

o     Property and Equipment

      Property and equipment are stated at cost and depreciated by the
      straight-line method over their estimated useful lives (3 to 10 years).

o     Goodwill

      The excess of cost over the fair value of net assets acquired of purchased
      business at the date of acquisition is amortized by the straight-line
      method over 15 years.

o     Income Taxes

      Income taxes are determined using the liability method of accounting.
      Under this method, deferred tax assets and liabilities are determined
      based on differences between the financial reporting and tax basis of
      assets and liabilities. Additionally, the deferred tax items are measured
      using current tax rates. The principal types of differences between assets
      and liabilities for financial statement and tax return purposes are
      allowances, inventory and certain accrued liabilities.

o     Use of Estimates

      In preparing financial statements in conformity with generally accepted
      accounting principles, management is required to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      the disclosure of contingent assets and liabilities at the date of the
      financial statements, as well as revenues and expenses during the period.
      Significant estimates made by management include the allowance for
      doubtful accounts and inventory obsolescence. Actual results could differ
      from those estimates.

NOTE B - DISCONTINUED OPERATIONS

In March 1996, the Company entered into discussions to sell all of its
outstanding common stock. The transaction is expected to be completed in July
1996. In connection with this transaction, the Company's shareholders will form
a new company and purchase the assets and assume liabilities of the Distribution
Division at net book value. The Distribution Division has been treated as a
discontinued operation. Net assets of the Distribution Division are summarized
as follows:

The net assets of the Distribution Division have been classified a current asset
because of the pending sale. Included in net assets of the discontinued
operations is a liability under a defined benefit pension plan (Plan) amounting
to approximately $1.0 million. Management has notified its employees of the
Company's intent to freeze the Plan as of June 30, 1996, with the intent of
liquidating the Plan. Any benefit or obligation resulting from the liquidation
of the Plan will accrue to the Distribution Division.

NOTE J - FAIR VALUE OF FINANCIAL INSTRUMENTS

The financial instruments of the Company consist mainly of current receivables,
short-term credit, accounts payable, accrued liabilities and long-term debt. In
view of their short-term nature, the fair value of the items included in current
assets and current liabilities approximates their carrying value. The fair value
of the long-term loans approximates their carrying value, since they bear
interest at rates at or close to the prevailing market rates.

                    NOTES TO FINANCIAL STATEMENTS - UNAUDITED

                             June 30, 1996 and 1995

NOTE A - SUMMARY OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Technical Instrument Company (the Company) designs, manufactures, and
distributes microscopes and other precision optical instruments and equipment.
The Company has two divisions: a proprietary products division and a
distribution division (see Note B).

The Company's proprietary products division designs, manufactures, and
distributes precision optical equipment used by manufacturers of semiconductors
and other high technology products. The proprietary products division derives
approximately 45% of its revenues from international sales. The Company's
distribution division has an exclusive license to distribute microscopes and
other precision optical instruments in Northern California.

A summary of the Company's significant accounting policies applied in the
preparation of the accompanying financial statements follows:

o    Inventories
     Inventories are stated at the lower of cost (first-in, first-out method) or
     market.

o    Property and Equipment
     Property and equipment are stated at cost and depreciated by the
     straight-line method over their estimated useful lives (3 to 10 years).

o    Goodwill
     The excess of cost over the fair value of net assets acquired of purchased
     business at the date of acquisition is amortized by the straight-line
     method over 15 years.

o    Income Taxes
     Income taxes are determined using the liability method of accounting. Under
     this method, deferred tax assets and liabilities are determined based on
     differences between the financial reporting and tax basis of assets and
     liabilities. Additionally, the deferred tax items are measured using
     current tax rates. The principal types of differences between assets and
     liabilities for financial statement and tax return purposes are allowances,
     inventory, and certain accrued liabilities.

o    Use of Estimates
     In preparing financial statements in conformity with generally accepted
     accounting principles, management is required to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     the disclosure of contingent assets and liabilities at the date of the
     financial statements, as well as revenues and expenses during the period.
     Significant estimates made by management include the allowance for doubtful
     accounts and inventory obsolescence. Actual results could differ from those
     estimates.

NOTE B - DISCONTINUED OPERATIONS

In March 1996, the Company entered into discussions to sell all of its
outstanding common stock. The transaction was completed effective August 8,
1996. In connection with this transaction, the Company's shareholders formed a
new company and purchased the assets and assumed liabilities of the Distribution
Division at net book value. Accordingly, the Distribution Division has been
treated as a discontinued operation. Net assets of the Distribution Division are
summarized as follows:

                                                                       1996

The net assets of the Distribution Division have been classified as a current
asset because of the sale of the business. Included in net assets of the
discontinued operations is a liability under a defined benefit pension plan
(Plan) amounting to approximately $1.0 million. Management notified its
employees that it has frozen the Plan as of June 30, 1996, with the intent of
liquidating the Plan. Any benefit or obligation resulting from the liquidation
of the Plan will accrue to the Distribution Division.

NOTE I - FAIR VALUE OF FINANCIAL INSTRUMENTS

The financial instruments of the Company consist mainly of current receivables,
short-term credit, accounts payable, accrued liabilities, and long-term debt. In
view of their short-term nature, the fair value of the items included in current
assets and current liabilities approximates their carrying value. The fair value
of the long-term loans approximates their carrying value, since they bear
interest at rates at or close to the prevailing market rates.

                    PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

Effective as of August 8, 1996, Zygo completed its acquisition of Technical
Instruments Company. Prior to the acquisition, Technical Instrument Company
("TIC") was engaged in two businesses: the proprietary products division which
designs, develops, manufactures, markets, and sells microscopy systems and
subsystems, or modules, and a distribution division which acts as a sales
representative for other firms' products. Prior to the completion of the
acquisition of the TIC stock by Zygo, the distribution division was spun off
into a new company, Technical Instruments--San Francisco. The consideration
given for the stock acquired was approximately $11,700,000 in cash and common
stock of Zygo valued at $3,000,000. Zygo has accounted for the acquisition of
TIC as a purchase under U.S. generally accepted accounting principles ("GAAP").

The following pro forma consolidated balance sheets and consolidated statements
of operations (collectively, the "Pro Forma Financial Statements") were prepared
by Zygo to illustrate the estimated effects of the business combination with
TIC. The pro forma consolidated financial statements do not present the net
assets or results of operations of TIC's discontinued distribution segment.
Included are Pro Forma Consolidated Balance Sheets at June 30, 1996 and Pro
Forma Consolidated Statements of Operations for the fiscal year ended June 30,
1996 for Zygo and TIC consolidated. Note: The Pro Forma Financial Statements
were compiled using the TIC historical data for the comparable period to Zygo's
fiscal year end June 30, 1996.

The Pro Forma Financial Statements give retrospective effect to material
differences between Zygo's and TIC's accounting policies which are expected to
have a material impact on the consolidated financial statements. The Pro Forma
Financial Statements also give retrospective effect for the allocation of the
TIC purchase price to the assets and intangibles of TIC. Such intangibles
include patents, licenses, drawings and technology, workforce, customer lists,
in-process research and development, and goodwill. The Pro Forma Financial
Statements do not purport to represent what the consolidated financial position
or results of operations actually would have been if the consolidation had
occurred at the beginning of the periods or to project the consolidated
financial position or results of operations for any future date or period.

The Pro Forma Financial Statements should be read in conjunction with the
historical consolidated financial statements, including the notes thereto, of
Zygo and TIC, prepared in accordance with the U.S. GAAP which are included
elsewhere in this document.

purposes of the pro forma consolidated income statements.

Note 2.

The Pro Forma Combined Statements of Income do not present the immediate
nonrecurring charge of $10.1 million relating to "in-process research and

     consideration plus related transaction costs.
