NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

~~March~~June 3130, 2005

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.

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.

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.

~~Reclassifications~~Components of operating expenses

~~Certain~~Cost ~~prior-year~~of ~~amounts~~sales ~~have~~include ~~been~~all ~~reclassified~~expenses tothat ~~provide~~are ~~comparability~~related ~~with~~to the sold product or service in a direct ~~presentation~~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 ~~the~~sales ~~current~~as ~~year~~well ~~financial~~as ~~statements~~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 (e.g., IT consulting).

PFEIFFER VACUUM TECHNOLOGY AG NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

~~NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS~~Reclassifications ~~(UNAUDITED)~~

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.

~~On December 16, 2004, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No~~4. ~~123 (revised 2004), “Share-Based Payment,” which is a~~ Restructuring revision of SFAS No. 123, “Accounting for Stock-Based Compensation.” SFAS No. 123® supersedes Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees” and amends SFAS No. 95, “Statement of Cash Flows.” Generally, the approach in SFAS No. 123® is similar to the approach described in SFAS No. 123. However, SFAS No. 123® requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Pro forma disclosure is no longer an alternative. SFAS No. 123® must be adopted in the first interim or annual period beginning after January 1, 2006. Early adoption will be permitted in periods in which financial statements have not yet been issued. The Company plans to adopt SFAS No. 123® on January 1, 2006.

4 In July 2002, the FASB issued SFAS No. 146, ~~Inventories~~“Accounting for Costs Associated with Exit or Disposal Activities.” This Standard requires that a liability for costs associated with exit or disposal activities be recognized in the period in which the costs are incurred if a reasonable estimate of fair value can be made.

~~Inventories~~During ~~are~~the ~~stated~~third atquarter of 2004 and after other cost reduction measures proved ineffective, the Company ~~lower~~entered into a plan of ~~cost~~termination orwhich ~~market~~impacted employees in the DVD business. ~~Cost~~This business isdeals ~~determined~~with ~~using~~development and production of manufacturing lines for digital versatile discs and falls within the ~~first~~operating segment Germany. Due to the German Works Council Constitution Act (Betriebsverfassungsgesetz) the Company must reach and reached an agreement with its workers council regarding the provisions of the one-intime termination benefits for 51 employees. This agreement included the date of termination of each employment contract, amounts of termination ~~first-out~~payments ~~method~~and the payment date. The accrued amount includes only the severance payment and not regular salaries which are paid out during the minimum retention period and reflected as period costs. An employee will receive severance regardless of whether such employee remains with the Company for the minimum retention period.

~~Inventories~~The ~~consist~~redundancy ofplan was approved by the ~~following:~~management, having the corresponding authority to do so, the employees to be terminated, their function and their location were identified in this plan, each dismissed employee was able to calculate their individual indemnity by using the formula set up in the plan (depending on age, seniority and salary) and it was and is still unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

The total amount expensed in the third quarter of 2004 regarding this redundancy plan was approximately € 1.2 million. The accrued restructuring costs due to the redundancy program amounted to € 0.9 million at December 31, 2004 and decreased to approximately € 0.1 million at June 30, 2005, as payments were made. The remaining payment will be in the third quarter 2005.

5. Investment Securities

In the first quarter 2005, the Company purchased investment securities amounting to € 3.0 million, which will be held until final maturity and are consequently valued at carrying cost of acquisition.

The conversion feature entitles the bearer to convert each bond with a par value of € 128 into 50 non-par value shares of the Company, upon payment of a conversion price.

Shares exercisable at March 31, 2005 totaled 174,000.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions used for grants in 2002 and 2000: Risk-free interest rates ranging from 4% to 5%; expected lives ranging from 4.5 to 6 years; expected dividend yield of 1% to 2%; and expected volatility ranging from 30% to 40%.

SFAS 123 requires disclosure of pro forma information regarding net income and earnings per share as if the Company had accounted for its stock-based compensation to employees using the fair value method. For pro forma purposes, using the fair value method the Company’s net income would have been K€ 4,820 and earnings per share would have been € 0.55.

~~Total~~Discontinued ~~net sales amounted to € 37.6 million in the first quarter of 2005 and decreased by € 1.4~~operations: million or 3.6% from € 39.0 million in the previous year’s period. The major part of the sales decrease amounting to approximately € 2.6 million (thereof € 1.6 million due to the withdrawal of the DVD business in 2005) was recorded in Germany, partly offset by an increase in Europe (excluding Germany) of € 2.1 million. The Company’s net sales revenue in the U.S. increased in U.S. dollar by 2.8%. Due to the weakness of the U.S. dollar against the euro, the sales in the U.S. were adversely impacted by the effect of exchange rate differences amounting to approximately € 0.4 million. Sales in Asia reached in the first quarter of 2004 a higher-than-average level and amounted to € 7.0 million.
