On the stock exchange in Frankfurt, Pfeiffer Vacuum share performance virtually kept pace with the TecDAX development during the first six months of 2006. While the TecDAX advanced by 8.5% from 601 to 652 points, Pfeiffer Vacuum share prices increased by 5.8%. On January 2, 2006, the shares opened at € 46.76 and closed at € 49.47 on June 30, 2006. They reached their low for the period of € 44.45 on January 17, 2006. The high for the period of € 58.00 on May 12, 2006 was also the highest stock price ever recorded for Pfeiffer Vacuum shares.

The prices of Pfeiffer Vacuum ADRs on the NYSE, which are traded in U.S. dollars, reflect changes in the share price and changes in the exchange rate parity between the euro and the U.S. dollar over the course of the year 2006. The ADRs opened on January 3, 2006, at a price of US$54.82 and closed on June 30, 2006, at US$63.50. The highest price in the first six months was US$73.95 on May 10, 2006. The ADRs’ low for the period was US$53.81 on January 17, 2006.

As one of the highest dividend issuers in the TecDAX, Pfeiffer Vacuum distributed a dividend to its shareholders for the eighth year in a row in 2006 (€ 1.35 per share for fiscal year 2005). Following a proposal of Management Board and Supervisory Board the Shareholders’ Meeting agreed to a total dividend of € 11.7 million on May 31, 2006, up 50% from total prior year dividend of € 7.8 million.

The Pfeiffer Vacuum Group’s Business and Position

In the first six months of 2006, Pfeiffer Vacuum again increased its sales by 10.5% and its operating profit by 22.0% compared to the first half-year of 2005. Year on year, in fact, the second quarter of 2006 saw a sales rise by € 2.1 million or 5.2%.

Overall Economic Environment and Industry Situation

Overall, the growth rate of world economy in 2006 is expected to be flat compared to the year 2005, but resulting from a very heterogeneous development in the continents. The growth rate in the Asian region (without Japan) will slightly decrease but still remain on a high level. The development in Europe is expected to be significantly higher than in the year before, especially caused by satisfactory growth rates in Italy, France and Germany. The growth rate in the United States is estimated to be down from the year 2005 but still exceed the development in Europe. Political situations in the near and middle east and potential impacts from rising world energy prices complicate the forecast for the 2006 development.

The competitive situation in the vacuum industry, coupled with heightened competitive pressure in the vacuum market remained on the level of 2005. Due to permanent enhancements and new developments of our products we were able to hold our technological leading, resulting in an increase of our business in 2006.

Business

Our business operations include the development, manufacture, sale and service of vacuum pumps, vacuum measurement, components and analysis equipment and instruments, as well as vacuum systems.

Sales

Presented below are net sales by segment, by region and by product for the periods ended June 30, 2006 and 2005. It should be noted with respect to net sales by segment that the sales shown in this presentation were allocated on the basis of the location that invoiced the sales. The segment-based presentation thus shows net sales by subsidiaries. Net sales by region, on the other hand, include all sales in a given region, regardless of which subsidiary within the Pfeiffer Vacuum Group actually invoiced the sales. Net sales by segment and by region can thus differ from one another to a greater or lesser extent. Net sales in the Asian segment, for example, differ from those shown for the Asian region, as the Asian segment includes only the sales of our two Asian subsidiaries in India and Korea. The presentation for the Asian region, on the other hand, additionally includes sales generated directly with Asian customers by the German company.

The Pfeiffer Vacuum Group’s Business and Position

In net sales by segment, the sales of the German company generated through direct shipments to agents and/or customers outside Germany are significantly higher than German sales by region. Net sales in the U.S. region and the U.S. segment, on the other hand, are nearly identical, because virtually all sales in this region are handled by our American subsidiary.

Sales by Segment (Companies)

Pfeiffer Vacuum’s subsidiaries in the individual countries are independent legal entities with their own management which distribute the products and provide services. Accordingly, we identify our operating segments geographically. Due to the similarity of their economic characteristics, including nature of products sold, type of customers, method of product distribution and economic environment, we aggregate our European subsidiaries outside Germany into one reportable segment, “Europe (excluding Germany).”

Sales by Segment

		Three Months Ended								Six Months Ended
		June 30,								June 30,
K €		2006				2005				2006				2005
Net sales
Germany			18,110				17,645				37,319				33,527
Europe (excluding Germany)			12,373				12,277				24,922				25,541
United States			10,475				9,130				21,344				16,845
Asia			1,069				879				2,104				1,606
Total			42,027				39,931				85,689				77,519

Analysis of these numbers shows that we were essentially able to increase sales in all geographical segments. Only in the segment Europe (excluding Germany) our sales decreased slightly in the first quarter of 2006 compared to 2005, but in the second quarter we were able to reach a small increase. During the first six months of 2006, the strongest growth was recorded in the segment United States, where sales totaled € 21.3 million, up € 4.5 million, or 26.7%, from the comparable period the year before. This sales increase was enhanced by approximately € 0.9 million foreign exchange gains due to the strengthened U.S. dollar against the Euro. Expressed in U.S. dollars, the sales of our U.S. subsidiary rose by 21.1% to US$26.2 million.

In Germany, sales advanced by € 3.8 million, or 11.3%, to a total of € 37.3 million in the first six months 2006 compared to 2005. Germany thus continued to be the segment that accounted for the highest share of total sales (43.5%). Rigorous efforts aimed at winning new customers and expanding business with existing customers and new products enabled Pfeiffer Vacuum to go against the general economic trend in growing sales.

Sales by Region

To provide additional information, we are also presenting sales by region in the following table. It includes all sales in a given region, regardless of which company in the Pfeiffer Vacuum Group actually generated these sales.

Rest of world			747				471				946				853
Total			42,027				39,931				85,689				77,519

In the six month period ended June 30, 2006, our sales to the United States increased by € 4.5 million or 26.8% to € 21.2 million. Sales to the Asian region increased by € 3.2 million or 24.0% to € 16.5 million, primarily due to sales increases in Japan and India. Additionally, we gain ground in China on a small level. Accounting for 29.5% of total sales, Europe (excluding Germany) continues to be our largest market. While in Europe (excluding Germany) in the first half-year a decrease by 3.2% to € 25.3 million was recorded, in Germany the sales increased by 5.9% to € 21.7 million and offset this adverse effect.

Turbopumps have an overriding importance to us. During the first six months of 2006, this product line generated total sales of € 38.2 million,

The Pfeiffer Vacuum Group’s Business and Position

representing an increase by € 6.6 million, or 21.0%, over the prior year. Turbopumps generated 44.5% of our total sales (2005: 40.7%). Sales of measurement/analysis equipment, components also developed positively, rising by € 1.2 million, or 5.6%, to € 21.9 million as per end of June 2006. Backing pump sales and service sales recorded a moderate increase by € 0.6 million and € 0.4 million, respectively. On the other hand, there was a small decline by € 0.7 million in system sales.

Order Intake and Order Backlog

Our order intake increased from € 83.0 million in the first six months of 2005 by € 3.8 million to € 86.8 million in 2006. Generally, the first quarter of 2006 developed extremely positive compared to 2005, while the second quarter of 2006 was flat to the previous years period. In the six month period ended June 30, 2006, new orders in turbopumps increased by
€ 1.3 million, in backing pumps by € 1.3 million and in service by € 0.2 million, offset by € 0.8 million decrease in system orders. At June 30, 2006, the book-to- bill ratio, the quotient of new orders and sales amounted to 101.3%.

Our order backlog decreased by € 0.8 million, from € 31.4 million at June 30, 2005 to € 30.6 million at June 30, 2006. One reason is decreased order intake in systems within the second quarter and on the other hand fulfilled orders in turbo pumps.

Contracts are only recorded as orders when they are based upon binding contracts. The value of orders on hand should not be used to predict future sales and order volumes.

Cost of Sales and Gross Profit

The cost of sales incurred in the six months ended June 30, 2006, totaled € 43.1 million. This represents an increase of € 1.6 million over the € 41.5 million for the comparable period the year before. In the second quarter our cost of sales increased slightly from € 21.4 million in 2005 to € 21.5 million in 2006. The increase in both periods is predominantly attributable to our significantly raised sales. Our gross profit improved from € 36.1 million to € 42.6 million in the first six months of 2006 and from € 18.6 million to € 20.5 million in the second quarter of 2006 compared to the prior year, respectively. Our gross margin (gross profit as percentage of sales) increased from 46.5% in the first half-year 2005 to 49.7% in the current year’s period. In the second quarter of 2006 we recorded an increase to 48.8% from 46.5% in 2005.

A favorable product mix, the economies of scale and our permanent cost management in the production aligned with keeping our commodity prices for e.g. cast iron, stainless steel and aluminum at a virtually constant level, enables us to leverage our cost of sales.

The Pfeiffer Vacuum Group’s Business and Position

Selling and Marketing Expenses

Selling and marketing expenses totaled € 11.5 million as of June 30, 2006 as opposed to € 9.6 million for the corresponding period in the year before. Selling and marketing expenses increased by € 1.9 million primarily as a result of various marketing measures, e. g. corporate image campaign, trade fair participations, advertisements and print of new brochures. Our goal is still to expand our market share and to withdraw the competitive price pressure. Relative to sales, the ratio increased from 12.4% in the first six months of 2005 to 13.4% in 2006.

General and Administrative Expenses

In the six month period ended June 30, 2006, general and administrative expenses totaled € 6.9 million, up € 0.8 million from the comparable prior year’s period (€ 6.1 million). In the second quarter 2006 the general and administrative expenses turned back to normal level (€ 3.1 million), while the first quarter of 2006 was burdened with expenses related to the adoption of SOA 404 at end of fiscal year 2006 and additional personnel cost. Relative to sales, the ratio for the first six months 2006 increased from 7.8% in 2005 to 8.1%.

Research and Development Expenses

Research and development expenses amounted to € 3.4 million in both, the first half-year of 2006 and the first half-year of 2005. As a result of higher sales, however, the expense ratio declined in the same periods from 4.4% (2005) to 4.0% (2006). The research and development expenses increased in the second quarter of 2006 by € 0.1 million compared to the same period in 2005. The ratio was 4.1% in both quarters.

We will maintain the percentage of expenses allocated for research and development at a high level. We are dependent upon maintaining our technological edge in designing and manufacturing vacuum pumps, and invest in order to be able to continue to sustain our position on the world market, to expand our market shares and to open up new markets. All expenditures for research and development are expensed as they are incurred.

Operating Profit

During the first six months of 2006, operating profit rose sharply from € 17.0 million to € 20.7 million, representing growth of € 3.7 million or 22.0%. At € 10.2 million, the Company’s operating profit in the second quarter of 2006 was also up sharply from 2005 (€ 8.8 million).

The Pfeiffer Vacuum Group’s Business and Position

The ratio between operating profit and sales totaled 24.2% for the first six months of the year 2006, up 2.3 percentage points year on year.

Financial Income

Financial income comprises interest expense, interest income and exchange rate gains or losses. As of June 30, 2006, financial income totaled € 0.3 million, as opposed to € 1.5 million for the comparable period in 2005. This decrease is primarily due to foreign exchange rate changes; in 2006 we recorded a loss of € 0.4 million compared to a gain in 2005 of € 1.0 million.

Income Taxes

The Company’s effective tax rate of its continuing operations was 39.0% for the first six months of 2006 and 39.8% for the first six months of 2005. The effective tax rate for the second quarter 2006 was 39.0% (2005: 39.8%).

The tax rate used for calculation of the income tax benefit from discontinued operations in 2005 was 37.9%.

Income from Continuing and Discontinued Operations and Net Income

Income from continuing operations totaled € 12.7 million for the six month period ended June 30, 2006 compared to
€ 11.1 million at June 30, 2005, representing an improvement of € 1.6 million, or 14.1%. In the second quarter of 2006 income from continuing operations amounted to € 6.3 million and increased by € 0.5 million or 7.4% from the previous year’s amount (€ 5.8 million).

In fiscal year 2005 we recorded losses from discontinued operations (see Note 9 “Discontinued operations” to the Interim Financial Statements). These discontinued operations resulted in the first six months of 2005 in a loss of € 0.8 million (second quarter 2005: € 0.5 million). The net income of 2006 was not burdened with any expenses due to these discontinued operations. Additionally, we do not expect any charges in future periods.

Net income in the six months ended June 30, 2006 was € 12.7 million (2005: € 10.3 million) and in the three month period ended June 30, 2006 € 6.3 million (2005: 5.4 million).

The Pfeiffer Vacuum Group’s Business and Position

Financial Position

The financial position of the Pfeiffer Vacuum Group continues to be characterized by cash and cash equivalents on the assets side of the balance sheet and by shareholders’ equity on the opposite side. The balance sheet total on June 30, 2006, increased by 1.5%, or € 2.1 million, compared to December 31, 2005. On the asset side, the increase in the balance sheet total was predominantly attributable to the € 2.6 million increase in inventories to € 16.4 million, as well as the € 1.8 million increase in fixed assets. The cash flow statement shows the development of liquid assets.

Total shareholders’ equity increased by € 1.3 million. One important reason is an increase in additional paid-in capital by € 2.1 million primarily due to the conversion of convertible bonds and the recording of the conversion price (€ 1.9 million), offset by share buy-back amounting to € 1.0 million. The equity ratio decreased slightly from a high level of 81.1% in 2005 to 80.8% in 2006. The development of shareholders’ equity already includes the dividend payment totaling € 11.7 million (2005: € 7.8 million). Our higher-than-average shareholders’ equity continues to enable us to finance our investments and operations without having to resort to bank debt.

Cash Flow

Further on, we are able to generate required cash from operating activities to fund our day-to-day business and investment projects.

Cash flow from operating activities totaled € 11.4 million for the first six months of 2006 and represents an increase of € 1.9 million from the € 9.5 million total for the comparable period in 2005. Compared to the first half-year 2005, our higher inventories led to an increased cash usage of approximately € 2.0 million, offset by an increase in trade payables of approximately € 0.7 million (cash provided). Additionally, the increase in net income had a positive effect of approximately € 2.4 million on the cash flow provided by operating activities.

Net cash used in investing activities totaled € 3.4 million for the period ended June 30, 2006 compared to € 4.5 million cash provided by investing activities for the prior year’s period. In 2005 we purchased investment securities amounting to € 3.0 million and received € 9.0 million repayment of investment securities. Capital expenditures totaled € 3.5 million in 2006, and included the purchase of factory halls built on our ground amounting to € 1.9 million.

The Pfeiffer Vacuum Group’s Business and Position

The cash used in financing activities was predominantly impacted by the dividend payment to our shareholders amounting to € 11.7 million in 2006 compared to € 7.8 million in 2005. A dividend of € 1.35 per share for the year 2005 was approved at the Annual Shareholders’ Meeting in May 2006.

We distributed a total amount of € 11,732,207.40 to our shareholders. Additionally, the purchase of treasury stock led to a cash usage amounting to € 1.0 million. The cash received in connection with the conversion of convertible bonds totaled only € 1.0 million because a part of the conversion price was granted as employee loans and was recorded as non-cash transaction (please refer to Note 4 “Stock-based Compensation — Adoption of FAS 123R” to Interim Financial Statements).

Workforce

As of June 30, 2006, the Company employed a workforce of 684 people, 504 of them in Germany and 180 in other countries.

Risk Report

During the first six months of the 2006 fiscal year, there were no changes in the risks as described in our Annual Report (Geschäftsbericht) and our Annual Report on Form 20-F for the year ended December 31, 2005. Both reports are available on our homepage at www.pfeiffer-vacuum.net.

The Pfeiffer Vacuum Group’s Business and Position

Major Events in Fiscal 2006

Since the beginning of the 2006 fiscal year, there have not been any significant changes in the Company’s position or the industry environment.

Outlook

The forecast for the world economic growth in 2006 is still very low. We estimate that sales growth in the vacuum industry in 2006 will be the same as in the past fiscal year. Given our orders on hand and rising customer demand, we anticipate that our sales will grow faster than the market in 2006.

Nevertheless, we cannot exclude negative impacts — due to the US dollar exchange rate or significant increases in commodity prices — in the next few months.

Overall, we assume that along with constantly growing sales our profitability will remain in line with the last year or slightly improve.

1. The Company and Basis of Presentation

Pfeiffer Vacuum is a full-line manufacturer in the vacuum technology business offering solutions for a variety of customer applications relating to the generation, control and measurement of vacuum. The products developed and manufactured at the production facility in Asslar, Germany, include turbomolecular pumps, a range of backing pumps, such as rotary vane, Roots and dry pumps, complete pumping stations as well as customized vacuum systems, vacuum components and instruments.

Pfeiffer Vacuum distributes its products through a network of its own sales offices and subsidiaries as well as independent marketing agents. Moreover, there are service support centers in most major industrial locations throughout the world. The Company’s primary markets are located in Europe, the United States and Asia.

The Consolidated Financial Statements of Pfeiffer Vacuum Technology AG and its subsidiaries (“the Company” or “Pfeiffer Vacuum”) have been prepared in accordance with United States Generally Accepted Accounting Principles (U.S. GAAP). The interim financial statements reflect all adjustments (consisting only of normal recurring adjustments) which are necessary for a fair presentation of the financial position, results of operations and cash flows of the Company. For further information, please refer to the consolidated financial statements and footnotes thereto included in the Pfeiffer Vacuum Technology AG Annual Report (Geschäftsbericht) and the Annual Report on Form 20-F for the year ended December 31, 2005, both available at the Company’s homepage (www.pfeiffer-vacuum.net).

Pfeiffer Vacuum presents its Consolidated Financial Statements in euros (€).

2. Summary of Significant Accounting Policies

Consolidation Principles

All companies which Pfeiffer Vacuum Technology AG directly or indirectly controls are consolidated. The Company is considered to control an entity if it either directly or indirectly holds a majority of the voting rights and can therefore exercise a controlling influence.

All material intercompany gains and losses, receivables, liabilities, revenues and expenses are eliminated as part of the consolidation process.

Notes to the Interim Financial Statements (unaudited)

Use of Estimates

The preparation of the Consolidated Financial Statements requires management to make estimates and assumptions that affect the amounts of assets and liabilities on the date of the financial statements and the reported amounts of revenues and expenses during the reporting period that are reported in the financial statements and accompanying notes. These estimates and assumptions could differ from the actual results.

Components of Operating Expenses

Cost of sales include all expenses that are related to the sold product or service in a direct or indirect manner, for example, material consumption (including inbound freight charges), production related wages and salaries, purchasing and receiving costs, inspection costs, warehousing costs and certain service costs. Inventory excess and obsolescence charges are also recorded in cost of sales as well as warranty related expenses. Selling and marketing expenses mainly include wages and salaries, costs for marketing and advertising and costs related to trade fairs and conventions as well as other merchandising costs (including catalogs, brochures, etc.). General and administrative expenses predominantly include wages and salaries, allowance for doubtful accounts, audit and other general consulting fees and other costs that relate to the company as a whole.

Reclassifications

Certain prior-year amounts have been reclassified to provide comparability with the presentation of the current year financial statements.

Foreign Currency Translation

The financial statements of the Company’s foreign subsidiaries have been translated into euros (€) in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 52, “Foreign Currency Translation”. The functional currency of all of the Company’s foreign subsidiaries is the applicable local currency in which that entity conducts its business. When translating foreign functional currency financial statements, year-end exchange rates are applied to the assets and liabilities, while average annual exchange rates are applied to income statement accounts. The resulting translation adjustments are recorded as accumulated other comprehensive income (loss).

3. New U.S. Legislation and Accounting Rules

As a result of the Company’s listing at New York Stock Exchange, it is subject not only to the provisions of German law (corporation, codetermination and capital market legislation) and of its own Articles of Association but also to the licensing requirements of the New York Stock Exchange. American capital market legislation — specifically the Sarbanes-Oxley Act and the rules and regulations of the Securities and Exchange Commission (“SEC”) — also apply to Pfeiffer Vacuum.

4. Stock-based Compensation — Adoption of SFAS 123R

The Company established a convertible bond arrangement also known as the employee participation program implemented on July 7, 2002 and running through 2007. The purpose of this employee participation program is to provide compensation and motivate the management and some key employees by providing them with an opportunity to share in the Company’s stock price development and to participate in the future growth of Pfeiffer Vacuum Technology AG and its subsidiaries.

In prior years, when stock option plans were not allowed under German law, the use of convertible bonds was common practice among German public companies. Pfeiffer Vacuum’s employee participation program utilizes convertible bonds in lieu of stock options. Under this program, the Company provides an employee a loan to purchase a Company-issued convertible bond. The loan and the nominal value of the convertible bond are equal to each other (and to what would be the exercise price in the case of a stock option), and the interest rate on the loan is equal to the interest rate on the convertible bond. Accordingly, there is no out-of-pocket cost to the Company or to the employee for either the loan or the convertible bond (as in the case of a stock option). The employee may then exercise her/his right to convert the bond to Company stock (equivalent to the exercise of a stock option) by repaying the loan to the Company for the nominal value of the convertible bond (which is equal to what would be the exercise price in the case of a stock option).

Within the scope of this employee participation program, on July 7, 2002, the Company issued 4,600 convertible bonds having an aggregate principal amount of € 0.6 million to members of management and certain salaried employees of the Company in Germany and other countries.

The conversion feature entitles the bearer to convert each bond into 50 no-par ordinary shares of Pfeiffer Vacuum. The conversion price is based upon 110% of the average closing price on the Frankfurt Stock Exchange for the last ten trading days prior to issuance and was set at € 42.86 per share and includes a nominal amount of € 2.56 and an additional payment of €40.30.

Notes to the Interim Financial Statements (unaudited)

There were 132,950 option shares, relating to the convertible bonds for the 2002 issue outstanding at June 30, 2006. Fair value at the date of grant was € 10.35 per ordinary share option. Each holder of convertible bonds could convert up to 30% of such bonds to ordinary shares subsequent to the Annual Shareholders’ Meeting in 2004, up to 60% following the Annual Shareholders’ Meeting in 2005 and up to 100% following the Annual Shareholders’ Meeting in 2006. The final conversion date is December 9, 2007. Conversion is only possible during specific periods of time.

The convertible bonds bear interest at 6% p.a. and are redeemable at their principal amount on December 10, 2007, unless previously converted or called. The bonds may be called by the Company at their principal amount upon termination of employment. Employees were given the opportunity of financing the purchase of the convertible bonds through interest-bearing employee loans. These loans bear interest at the same fixed rate as the bonds, have identical terms, are classified as other non-current assets in the balance sheet and are repayable upon conversion of the bonds or if the bonds are called by the Company upon termination of employment.

There is a right of setoff for both, principal and interest between the loan and the bond. Employee loans granted under this program amounted to K€ 301 as of June 30, 2006.

Should the conversion right be exercised, interest on the converted convertible bonds shall cease to accrue at the day on which said conversion right was exercised. The shares of stock stemming from exercise of conversion rights shall participate in earnings from the beginning of the fiscal year in which said shares of stock were created through exercise of the conversion rights.

As of June 30, 2006, employees had forfeited 1,000 of these convertible bonds having an aggregate principal value of € 128,000 and repaid the corresponding employee loans. The Company did not recognize any compensation expense for the stock-based compensation awards in the years 2005, 2004 and 2003.

The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model, with the following assumptions being used for grants issued in 2002. The risk-free interest rate was 4.5%; expected term 4 years; expected dividend yield of 1%; and expected volatility 30%. Expected volatility was based on historical volatility. The risk-free rate is based on the average interest rate of German government bonds. Expected term represents the period of time that options are expected to be outstanding.

Notes to the Interim Financial Statements (unaudited)

A summary of option shares related to the convertible bonds of the 2002 issue is as follows:

Shares Related to the Convertible Bonds

						Weighted Average
		Number of				Exercise Price
		Shares Outstanding				€ per Share
Convertible shares outstanding January 1, 2005			190,000				42.86
Granted			—				—
Exercised			—				—
Forfeited			(10,000	)			42.86
Convertible shares outstanding December 31, 2005			180,000				42.86
Granted			—				—
Exercised			(47,050	)			42.86
Forfeited			—				—
Convertible shares outstanding June 30, 2006			132,950				42.86

132,950 option shares of this program were exercisable at June 30, 2006 and are non-vested. In December 2004 the Financial Accounting Standards Board (“FASB”) issued SFAS 123 (revised 2004), “Share-Based Payments” (“SFAS 123R”). At January 1, 2006, the Company adopted SFAS 123R, using the modified-prospective transition method. Pfeiffer Vacuum has a fixed plan (under the convertible debt arrangement) with the number of shares fixed at 230,000 and the exercise price fixed at € 42.86. The exercise price was greater than the quoted market price of the stock as it was based on 110% of the ten day average traded stock prior to the grant date plus € 2.56 (€ 128 face value of each bond divided by 50 shares).

All participants were employees within the consolidated Pfeiffer Vacuum Group as defined under common law. There have been no program modifications to date.

In the first six months of the fiscal year 2006, the Company recognized K€ 232 of total compensation costs, as the four year vesting period ends in June 2006. In the cash flow statement these expenses are disclosed in a separate line.

Under German tax law, expense related to share-based payment arrangements or specifically expense related to the intrinsic value of an instrument on a specified date is not tax deductible. Consequently, there were no deferred taxes recorded as part of SFAS 123R adoption.

In the conversion period in June 2006, the bearers of the bonds converted 941 bonds into 47,050 new no-par value ordinary shares of the Company. As a result of the conversion the share capital increased by € 120,448 and the additional paid-in capital increased by € 1,896,115.

Notes to the Interim Financial Statements (unaudited)

The employees were given the opportunity to finance the conversion of the bonds through interest bearing loans. These loans bear interest of 6% per annum and can be redeemed by the employee at any time and mature on September 30, 2006. As of June 30, 2006 these loans amounted to K€ 859; as of July 27, 2006 they were reduced to K€ 11.

Wihtin the scope of this conversion, Manfred Bender, Chief Financial Officer of Pfeiffer Vacuum, converted 100 convertible bonds into 5,000 no-par value shares of the Company and sold these shares in June 2006. He did not access any loan from the Company. The announcement required by § 15a Wertpapierhandels-gesetz (German Securities Trade Act) was duly published.

5. Supervisory Board

At June 30, 2006, treasury stock totaling approximately € 3.5 million was repurchased and consists of 122,076 ordinary shares valued at cost. Thereof 22,000 shares were repurchased within the scope of the new authorization and 100,076 shares in prior years.

9. Discontinued Operations

unrecognized net obligation			6				6				12				12
Net pension cost			548				320				1,099				639

The increase in pension expense is predominantly due to lower expected returns on assets and higher amortization for actuarial losses. Both factors are caused by the decreased interest rate level in fiscal 2005.
