FORWARD LOOKING STATEMENTS

All statements other than statements of historical fact included in this Form 10-Q Quarterly Report regarding our financial position, business strategy, plans, anticipated growth rates, and objectives of management for
future operations (as well as these factors as they may apply to our customers, suppliers, and others with whom we have critical business relationships) are forward-looking statements. Forward-looking statements are intended to provide
managements current expectations or plans for the future operating and financial performance based upon information currently available and assumptions currently believed to be valid. Forward-looking statements can be identified by the use of
words such as anticipate, believe, estimate, expect, intend, plans, strategy, project, and other words of similar meaning in connection with a discussion
of future operating or financial performance. Actual results could differ materially from those contemplated by the forward-looking statements as a result of certain factors. Among the important factors that could cause actual events to differ
materially from those in the forward-looking statements are fluctuations in capital spending of our customers, fluctuations in net sales to our major customer, manufacturing and supplier risks, dependence on and timing of new product development,
rapid technological and market change, risks in international operations, dependence on proprietary technology and key personnel, length of the sales cycle, environmental regulations, and stock price fluctuations. Any forward-looking statements
included in this Quarterly Report speak only as of the date of this document. ZYGO undertakes no obligation to publicly update or revise forward-looking statements to reflect events or circumstances occurring after the date of this Form 10-Q.
Further information on potential factors that could affect our business is described in our reports on file with the Securities and Exchange Commission, including our Form 10-K for the fiscal year ended June 30, 2006.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS(Dollars in thousands, except for per share amounts)

Note 1: Principles of Consolidation and PresentationZygo
Corporation is a worldwide supplier of optical metrology instruments, precision
optics, and electro-optical design and manufacturing services, serving customers
in the semiconductor capital equipment and industrial markets. The accompanying
condensed consolidated financial statements include the accounts of Zygo Corporation
and its subsidiaries (ZYGO, we, us, our or Company).
All material transactions and accounts with the subsidiaries have been eliminated
from the condensed consolidated financial statements. The results of operations
for the three and six months ended December 31, 2006 are not necessarily indicative
of the results to be expected for the full fiscal year.

The Condensed Consolidated Balance Sheet at December 31, 2006, the Condensed Consolidated Statements of Operations for the three and six months ended December 31, 2006 and 2005, and the Condensed Consolidated Statements of
Cash Flows for the six months ended December 31, 2006 and 2005 are unaudited but, in managements opinion, include all adjustments, consisting only of normal recurring accruals, necessary for a fair presentation of the results of the interim
periods. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended June 30, 2006, including items
incorporated by reference therein.

Note 2: Earnings Per ShareBasic
and diluted earnings per share are calculated in accordance with Statement of
Financial Accounting Standards (SFAS) No. 128, Earnings Per Share. For the second quarter of fiscal 2007, 837,612
of the Companys outstanding stock options and restricted stock awards (Stock Grants) (899,412 for the first six months of fiscal 2007) were excluded from the calculation of diluted earnings per share. For the second quarter of
fiscal 2006, 749,890 of the Companys outstanding Stock Grants (1,133,190
for the first six months of fiscal 2006) were excluded from the calculation of
diluted earnings per share. These Stock Grants could be included in the calculation
in the future if the average market value of the common shares increases.

The following table sets forth the reconciliation of basic weighted average shares outstanding and diluted weighted average shares outstanding:

|                                 |  | Three Months Ended December 31, |  | Six Months Ended December 31,

Note 3: Recent Accounting PronouncementsIn
June 2006, the Financial Accounting Standards Board ("FASB") issued FASB Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 clarifies the accounting for uncertainty in income taxes
recognized in the Company's financial statements in accordance with FASB Statement No. 109, "Accounting for Income Taxes." The
provisions of FIN 48 are effective for our fiscal year beginning July 1, 2007.
We are currently evaluating the impact of the provisions of FIN 48 on our company.

In September 2006, the SEC issued Staff Accounting Bulletin 108 (SAB 108) to address diversity in practice in quantifying financial statement misstatements. SAB 108 requires that we quantify misstatements based
on their impact on each of our financial statements and related disclosures. SAB 108 is effective as of the end of our 2007 fiscal year, allowing a one-time transitional cumulative effect adjustment to retained earnings as of June 30, 2007 for
errors that were not previously deemed material, but are material under the guidance in SAB 108. We do not expect the adoption of SAB 108 to have a material effect on our financial statements.

In September 2006, the FASB issued Statement of Financial Accounting Standard ("SFAS") No. 157, "Fair Value Measurements" ("FAS 157"). FAS 157 defines fair value, establishes a framework for measuring fair value in
accordance with generally accepted accounting principles, and expands disclosures about fair value measurements. The provisions of FAS 157 are effective for our fiscal year beginning July 1, 2008. We are currently evaluating the impact of the
provisions of FAS 157 on our company.

In September 2006, the FASB issued SFAS No. 158, "Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans" ("FAS 158"). FAS 158 requires employers to fully recognize the obligations associated with
single-employer defined benefit pension, retiree healthcare, and other postretirement plans in their financial statements. The provisions of FAS 158 are effective as of the end of our fiscal year ending June 30, 2007. We are currently evaluating the
impact of the provisions of FAS 158 on our company.

Note 4: Share-Based PaymentsWe recorded share-based compensation expense for the three months ended December 31, 2006 and 2005 of $508 and $816, respectively, with a related tax benefit of $183 and $292, respectively. Shared-based
compensation for the six months ended December 31, 2006 and 2005 was $1,109 and $1,190, respectively, with a related tax benefit of $399 and $426, respectively. Beginning after July 1, 2005, we made changes to our employee stock
purchase plan which rendered the plan non-compensatory in accordance with SFAS No. 123(R), Share-Based Payment.

Stock-OptionsAn independent third party assisted the Company in determining the Black-Scholes weighted average assumptions utilized in both fiscal 2007 and 2006 stock option valuations. The key assumptions for this valuation method
include the expected term of the option, stock price volatility, risk-free interest rate, dividend yield, exercise price, and forfeiture rate. Many of these assumptions are judgmental and highly sensitive in the determination of compensation
expense. Under the assumptions indicated below, the weighted-average fair value of stock option grants for the three and six months ended December 31, 2006 were $6.62 and $6.15, respectively. The weighted-average fair value of stock option
grants for the three and six months ended December 31, 2005 were $6.79 and $5.41, respectively. The table below indicates the key assumptions used in the option valuation calculations for options granted in the three and six months ended
December 31, 2006 and 2005, and a discussion of our methodology for developing each of the assumptions used in the valuation model:

|                        |  | Three Months Ended December 31, |  | Six Months Ended December 31,
|----------------------- |  | ------------------------------- |  | -----------------------------
|                        |  | 2006                            |  | 2005                         
|Term                    |  | 4.1 Years                       |  | 4.1 Years                    
|Volatility              |  | 52.1%                           |  | 52.9%                        
|Dividend yield          |  | 0.0%                            |  | 0.0%                         
|Risk-free interest rate |  | 4.7%-4.8%                       |  | 4.4%                         
|Forfeiture rate         |  | 10.7%                           |  | 10.6%                        

Term This is generally the period of time over which the options granted are expected to remain outstanding. Options granted have a maximum term of ten years. An increase in
the expected term will increase compensation expense.

Volatility This is a measure of the amount by which a price has fluctuated or is expected to fluctuate. Volatilities are based on implied volatilities from traded options of
ZYGOs shares, historical volatility of ZYGOs shares, and other factors, such as expected changes in volatility arising from planned changes in ZYGOs business operations. An increase in the expected volatility will increase
compensation expense.

Dividend Yield We did not make any dividend payments during the last five fiscal years and we have no plans to pay dividends in the foreseeable future. An increase in the
dividend yield will decrease compensation expense.

Risk-Free Interest Rate This is the U.S. Treasury rate for the week of the grant having a term equal to the expected term of the option. An increase in the risk-free interest
rate will increase compensation expense.

Forfeiture Rate This is the estimated percentage of options granted that are expected to be forfeited or canceled before becoming fully vested. An increase in the forfeiture
rate will decrease compensation expense.

Restricted StockOur share-based compensation expense also includes the effects of restricted stock grants. The compensation expense related to restricted stock grants is determined based on the market price of our stock at the date of
grant applied to the total number of shares that are anticipated to fully vest, which is then amortized over the expected term.

Note 7: Property, Plant, and Equipment
Property, plant, and equipment are stated at cost. Maintenance and repairs are charged to expense as incurred. Management evaluates, on an ongoing basis, the carrying value of our property, plant, and equipment and makes
adjustments when impairments are identified. Depreciation is based on the estimated useful lives of the various classes of assets and is computed using the straight-line method. At December 31, 2006 and June 30, 2006, property, plant, and equipment
were as follows:

Note 8: Intangible AssetsIntangible assets include patents, trademarks, and license agreements. The cost of intangible assets is amortized on a straight-line basis over estimated useful lives ranging from 5-17 years. Intangible assets, at cost, at
December 31, 2006 and June 30, 2006 were as follows:

|                         |  | December 31, |        | June 30,
|------------------------ |  | ------------ | ------ | --------
|                         |  | 2006         |        | 2006    
|Patents and trademarks   |  | $            | 7,265  |         
|License agreements       |  |              | -      |         
|                         |  |              | 7,265  |         
|Accumulated amortization |  |              | (1,249 | )       
|Total                    |  | $            | 6,016  |         

Intangible amortization expense was $81 and $61 for the three months ended December 31, 2006 and 2005, respectively, and $155 and $168 for the six months ended December 31, 2006 and 2005, respectively.
Amortization expense related to certain intangible assets is included in cost of goods sold in the Condensed Consolidated Statements of Operations.

Note 9: WarrantyA
limited warranty is provided on our products for periods ranging from 3 to 18
months and allowances for estimated warranty costs are recorded during the period
of sale. The determination of such allowances requires management to make estimates
of product return rates and expected costs to repair or replace products under
warranty. If actual return rates or repair and replacement costs, or both, differ
significantly from managements estimates, adjustments
to the expense will be required.

The following is a reconciliation of the accrued warranty liability, which is included in the other accrued liabilities in the Condensed Consolidated Balance Sheets:

Note 10: Segment Information

During the second quarter of fiscal 2007, we reorganized the business into two operating divisions  Metrology and Optics. Beginning with this fiscal quarter, we have begun reporting our segments as Metrology and
Optics. Prior to this quarter, our segments were reported as Semiconductor and Industrial. Prior year segment information has been restated in a manner consistent with our new reporting segments.

ZYGOs Metrology segment consists of OEM and in-line products primarily for the semiconductor and industrial markets. The Optics segment consists of components and opto-mechanical assemblies primarily for the medical,
defense, and aerospace markets. For the three and six months ended December 31, 2006 and 2005, segment sales and gross profit are as follows:

Note 11: Transactions with Stockholder

Sales to Canon Inc., a stockholder, and Canon Sales Co., Inc., a distributor of certain of our products in Japan and a subsidiary of Canon Inc. (Canon), amounted to $13,026 (29% of net sales) and $25,643
(30% of net sales) for the three and six months ended December 31, 2006 as compared with $15,628 (36% of net sales) and $27,981 (36% of net sales) for the comparable prior year periods, respectively. Included in these aggregate sales to
Canon are sales related to development services of certain interferometers of $1,594 and $3,880 for the three and six months ended December 31, 2006, respectively, as compared with $5,611 and $9,572 for the three and six months ended
December 31, 2005, respectively. Selling prices of products sold to Canon are based, generally, on the terms customarily given to distributors. Revenues generated from the development agreements are recorded on a cost-plus basis.

At December 31, 2006 and June 30, 2006, there were, in the aggregate, $5,596 and $5,966, respectively, of trade accounts receivable from Canon. In addition, Canon Inc. paid us progress payments related to the
development services of certain interferometers. The total progress payments related to the development services remaining at December 31, 2006 was $91.

Note 12: Hedging Activities

We enter into foreign currency forward contracts to reduce the impact of adverse fluctuations on earnings associated with foreign currency exchange rate changes. We do not enter into any derivative transactions for
speculative purposes. These contracts are not designated as cash flow, fair value, or net investment hedges under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended, and therefore, are marked-to-market
with changes in fair value recorded in the Condensed Consolidated Statement of Operations. These contracts are entered into for periods consistent with the expected currency transaction exposures, generally three to six months. Any gains and losses
on the fair value of these contracts should largely offset corresponding losses and gains on the underlying transactions.

As of December 31, 2006, we had five currency contracts outstanding involving our Japanese and European operations aggregating $4,600. For the three months ended December 31, 2006 and 2005, we recognized losses from
foreign currency forward contracts of $88 and $23, respectively. For the six months ended December 31, 2006 and 2005, we recognized gains from foreign currency forward contracts of $71 and $59, respectively. These gains and losses
are substantially offset by foreign exchange losses and gains on intercompany balances recorded by our subsidiaries. These net gains and losses are included in other income in the Condensed Consolidated Statements of Operations.

Note 13: Income Taxes

The income tax rate for the three and six months ended December 31, 2006 was 35%. The income tax rate for the three and six months ended December 31, 2005 was 34% and 35%, respectively. The tax rate for the three month
period ended December 31, 2005 was favorably impacted by the release of a foreign tax reserve. For the six month periods, fiscal 2006 included the release of a foreign tax reserve and fiscal 2007 included a decrease in earnings in higher tax foreign
jurisdictions and a decrease in monies repatriated from foreign jurisdictions.

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

OVERVIEW

Zygo Corporation is a worldwide supplier of optical metrology instruments, precision optics, and electro-optical design and manufacturing services, serving customers in the semiconductor capital equipment and industrial
markets. Optical metrology instruments encompass non-contact optical measurement instruments. Precision optics products consist of high performance macro-optics components, optical coatings, and optical system assemblies. We conduct the majority of
our manufacturing in our 153,500 square foot facility in Middlefield, Connecticut and our 22,560 square foot facility in Tucson, Arizona.

During the second quarter of fiscal 2007, we reorganized our business into two operating divisions  Metrology and Optics. Consistent with this reorganization, beginning with this fiscal quarter, we have begun
reporting our operating segments as Metrology and Optics. Operating segments are components of our company about which separate financial information is available that is evaluated regularly by the chief operating decision maker, who is our chief
executive officer, in deciding how to allocate resources and in assessing performance. The Metrology segment consists of OEM and in-line products. The Optics segment consists of components and opto-mechanical assemblies primarily for the medical,
defense, and aerospace markets. These two business segments continue to serve two global markets: semiconductor and industrial. Our semiconductor market product offerings include OEM solutions for the semiconductor capital equipment industry and
direct supplied in-line automated process metrology and inspection systems for both flat panel display and chip manufacturing. Our industrial market products serve the automotive, consumer electronics, defense, aerospace, and medical markets, as
well as any other markets other than semiconductor. Industrial market products include optical components, optical systems and measurement-based process control systems for defense, aerospace, and medical device customers and measurement-based
process control and yield-enhancement systems for automotive and consumer electronics customers.

We also perform development services, which have accounted for a significant amount of our revenue over the past several years. These development services contracts with Canon Inc. have been substantially completed as of
December 31, 2006. In fiscal 2006, we recognized $20.0 million on these development services contracts and have recognized a total of $3.9 million during the first six months of fiscal 2007. Currently, we do not expect comparable total sales
to be adversely affected year over year due to the completion of the development services contracts. Increases in overall sales, including new product sales in the current quarter, coupled with strong orders and commitments, are expected to more
than offset the decrease in the development services revenue in the current year.

We achieved an order level for the second quarter of fiscal 2007 of $49.7 million as compared with $47.8 million for the first quarter of fiscal 2007 and $50.1 million for the second quarter of fiscal 2006. This
order flow increased backlog at December 31, 2006 to $92.4 million. Orders in the second quarter of fiscal 2007 for the Metrology and Optics segments were $37.0 million and $12.7 million, respectively. Stage metrology lithography orders,
which were significantly higher in the first two quarters of fiscal 2007 as compared with the first two quarters of fiscal 2006, contributed to the backlog. For fiscal 2007, the Company expects these lithography orders to be $45-$50 million,
similar to the stage metrology lithography orders in fiscal 2006. Orders are included in our backlog to the extent they are expected to be delivered within a twelve month period. Backlog does not include commitments from customers with expected
delivery dates beyond twelve months.

Research, development, and engineering (R,D&E) expenses increased by $3.6 million to $10.6 million, which represents 12% of net sales for the first six months of fiscal 2007 as compared with 9% of
net sales for the first six months of fiscal 2006. We anticipate continued higher R,D&E expenses for the remainder of the fiscal year as compared with the prior fiscal year. We continue to devote resources to our semiconductor initiatives and
the development of other new products and technologies, as well as to enhancing our existing core technology products.

CRITICAL ACCOUNTING POLICIES, SIGNIFICANT JUDGMENTS, AND ESTIMATES

The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally
accepted in the United States of America. The preparation of these condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses, and related
disclosures at the date of our condensed consolidated financial statements. On an on-going basis, management evaluates its estimates and judgments, including those related to bad debts, inventories, marketable securities, warranty obligations,
income taxes, long-lived assets, and share-based payments. Management bases its estimates and judgments on historical experience and current market conditions and on various other factors that are believed to be reasonable under the circumstances,
the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from

these estimates under different assumptions or conditions. As discussed in Item 7, Managements Discussion and Analysis of Financial Condition and Results of Operations of the Companys Annual Report
on Form 10-K for the fiscal year ended June 30, 2006, management considers the Companys policies on Revenue Recognition and Allowance for Doubtful Accounts; Inventory Valuation; Other than Temporary Impairment of Marketable Securities;
Share-Based Compensation; Warranty Costs; Accounting for Income Taxes; Valuation of Long-Lived Assets; and accruals for Health Insurance to be critical accounting policies due to the estimates, assumptions, and application of judgment involved in
each.

Overall, net sales increased 3% in the second quarter of fiscal 2007 as compared with the prior year. Net sales of products, which do not include development services, increased 13% in the second quarter of fiscal 2007 as
compared with the prior year period. Metrology sales decreased by 8% in the second quarter of fiscal 2007 as compared with the prior year, primarily due to the anticipated decline in development service revenues of $4.0 million. Excluding
development services, metrology sales increased 5% as compared with the prior year period. This increase in product sales was primarily due to volume increases in lithography sales of $2.6 million. Optics sales increased by 41% the second
quarter of fiscal 2007 as compared with the prior year period. This increase was across all product categories with the largest revenue increase of $1.9 million occurring in Optical Systems Solutions, which includes sales of optical assemblies
for the National Ignition Facility and medical device equipment.

Net sales increased 10% for the six months ended December 31, 2006 as compared with the prior year. Metrology sales increased 7% in the first six months of fiscal 2007 as compared with the prior year. This increase was due
primarily to volume increases in lithography sales of $6.3 million, display solutions of $2.8 million, and semiconductor solutions of $0.9 million, partially offset by the anticipated decline in development services of $5.7 million.
Optics sales increased by 19% for the six months ended December 31, 2006 as compared with the prior year period. This increase occurred across all product categories with Optical Systems Solutions contributing $2.0 million of the
increase.

Sales in U.S. dollars for the three and six months of fiscal 2007 were approximately 80% of total net sales for the periods. For our sales which are based in foreign currency, we are exposed to foreign exchange fluctuations
from the time customers are invoiced in foreign currency until collection occurs. Significant changes in the values of foreign currencies relative to the value of the U.S. dollar can impact the sales of our products in export markets, as would
changes in the general economic conditions in those markets. In the absence of a substantial increase in sales orders in currencies other than U.S. dollars, we believe a 10% appreciation or depreciation of the U.S. dollar against the Euro and Yen
would have an immaterial impact on our condensed consolidated financial position and results of operations.

Gross profit as a percentage of sales for the second quarter and first six months of fiscal 2007 was 44%, an increase of 5 percentage points as compared with prior year periods. Improved factory performance and material
cost reductions across both segments, as well as product mix, contributed to the overall increase of the gross profit as a percentage of sales in the fiscal 2007 over the prior year periods. We are continuing to implement lean manufacturing
initiatives which have contributed to improved utilization of our manufacturing resources. In addition, certain products in the Optics division had improved margins as we increased production levels. Development services, which have historically
carried a lower gross profit as a percentage of sales, were less than 5% of net sales in fiscal 2007 periods as compared with over 10% in the comparable prior periods.

The second quarter increase in SG&A was primarily due to increased selling expenses related to personnel costs, including commissions, and increased marketing activity. For the six months ended December 31, 2006, the
increase in SG&A was due primarily to new marketing initiatives of $0.4 million, foreign office expense of $0.4 million as we continue to expand our presence internationally, and selling expenses related to personnel costs of $0.4
million. We continue to increase our presence in the Asia territories with increased technical sales and support staff.

The increase in RD&E for the quarter ended December 31, 2006 as compared with the prior year period was primarily due to continued development efforts on our semiconductor initiatives of $0.6 million and development
efforts on new technologies for our display solutions of $0.4 million. We also continued ongoing development of our core technologies. The prior year period expenses include a reduction of $0.7 million for a customer reimbursement of
RD&E. The increase in RD&E for the six months ended December 31, 2006 was primarily driven by development efforts on semiconductor initiatives of $1.8 million, continued efforts on display solutions of $0.6 million, and continued
development of the helmet mounted display for defense applications of $0.3 million in the first half of fiscal 2007, and customer reimbursement of $0.7 million of RD&E efforts in the prior year period.

Other income for the three and six months ended December 31, 2006 increased by $0.2 and $0.5 million, respectively, over the prior year periods. This increase was primarily attributable to the cumulative year over
year effect of increases in yields on bond investments and money market investments.

The income tax rate for the three and six months ended December 31, 2006 was 35%. The income tax rate for the three and six months ended December 31, 2005 was 34% and 35%, respectively. The tax rate for the three month
period ended December 31, 2005 was favorably impacted by the release of a foreign tax reserve. For the six month periods, fiscal 2006 included the release of a foreign tax reserve and fiscal 2007 included a decrease in earnings in higher tax foreign
jurisdictions and a decrease in monies repatriated from foreign jurisdictions.

TRANSACTIONS WITH STOCKHOLDER

Sales to Canon Inc., a stockholder, and Canon Sales Co., Inc., a distributor of certain of our products in Japan and a subsidiary of Canon Inc., amounted to $13.0 million (29% of net sales) and $25.6 million (30% of
net sales) for the three and six months ended December 31, 2006, as compared with $15.6 million (36% of net sales) and $28.0 million (36% of net sales) for the comparable prior year periods, respectively. Included in these aggregate sales to
Canon are sales related to development services of certain interferometers of $1.6 million and $3.9 million for the three and six months ended December 31, 2006, respectively, as compared with $5.6 million and $9.6 million for the
three and six months ended December 31, 2005, respectively. Selling prices of products sold to Canon are based, generally, on the terms customarily given to distributors. Revenues generated from the development agreements are recorded on a cost-plus
basis.

At December 31, 2006 and June 30, 2006, there were, in the aggregate, $5.6 million and $6.0 million, respectively, of trade accounts receivable from Canon. In addition, Canon Inc. paid us progress payments related
to the development services of certain interferometers. The total progress payments related to the development services remaining at December 31, 2006 was $0.1 million.

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 2006, cash and marketable securities were $65.9 million, an increase of $0.4 million from $65.5 million at June 30, 2006. Cash flows from operating activities were $5.2 million for the first
six months of fiscal 2007 as compared with cash flows of $4.2 million for the comparable period in the prior year. The increase in operating cash flows for the six months of fiscal 2007 as compared with the prior year was primarily due to an
increase in accounts receivables collections of $6.1 million, and an increase in net income of $1.5 million, partially offset by an increase in inventory of $7.1 million to support the backlog.

Acquisitions of property, plant, and equipment totaled $4.8 million during the six months ended December 31, 2006.

There were no borrowings outstanding under our $3.0 million bank line of credit agreement at December 31, 2006 and June 30, 2006. The agreement contains certain financial covenants which, among others, relate to debt
service and consolidated debt ratios. The agreement expires in November 2007. Although cash requirements will fluctuate based on the timing and extent of various factors, management believes that cash generated from operations, together with the
liquidity provided by existing cash and marketable securities balances and borrowing capability, will be sufficient to satisfy our liquidity requirements for the next 12 months.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There have been no material changes that have occurred in our quantitative and qualitative market risk disclosures during the first six months of fiscal 2007. For discussion of our exposure to market risk, refer to Item
7a., Quantitative and Qualitative Disclosures about Market Risk, presented in our Annual Report on Form 10-K for the year ended June 30, 2006 filed with the Securities and Exchange Commission.

Item 4. Controls and Procedures

The effectiveness of our or any system of disclosure controls and procedures is subject to certain limitations, including the exercise of judgment in designing, implementing, and evaluating the controls and procedures, the
assumptions used in identifying the likelihood of future events, and the inability to eliminate misconduct completely. In designing, implementing, and evaluating the disclosure controls and procedures, our management recognized that any controls and
procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of
possible controls and procedures.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, carried out an evaluation, as of the end of the period covered by this report, of the effectiveness of our disclosure
controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based upon their evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the end of such period, our
disclosure controls and procedures were effective in recording, processing, summarizing and reporting on a timely basis information required to be disclosed by ZYGO in the reports that it files or submits under the Exchange Act and were effective in
ensuring that information required to be disclosed by ZYGO in the reports that it files or submits under the Exchange Act is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as
appropriate to allow timely decisions regarding required disclosure.

There were no changes in our internal control over financial reporting that occurred in our most recent fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over
financial reporting.
