IT IS IMPORTANT THAT YOUR SHARES BE REPRESENTED AT THE MEETING. THEREFORE, WHETHER OR NOT YOU PLAN TO ATTEND THE MEETING, PLEASE COMPLETE YOUR PROXY CARD AND RETURN IT IN THE ENCLOSED ENVELOPE, WHICH REQUIRES NO POSTAGE IF MAILED IN THE UNITED STATES. IF YOU ATTEND THE MEETING AND WISH TO VOTE IN PERSON, YOUR PROXY WILL NOT BE USED. By order of the Board of Directors, Lynnette C. Fallon SECRETARY Dated: May 14, 2001 PROXY STATEMENT The board of directors of Axcelis Technologies, Inc. ("Axcelis" or the "Company") is soliciting your proxy for use at the 2001 annual meeting of stockholders to be held on Thursday, June 28, 2001 and at any adjournment of the meeting. This proxy statement and the accompanying proxy card are first being sent or given to stockholders of Axcelis on or about May 14, 2001. GENERAL INFORMATION ABOUT VOTING WHO CAN VOTE. You may vote your shares of Axcelis common stock at the annual meeting if you were a stockholder of record at the close of business on April 30, 2001. On that date, there were 97,073,127 shares of common stock outstanding. You are entitled to one vote for each share of common stock that you held on the record date. HOW TO VOTE YOUR SHARES. You may vote your shares either by proxy or by attending the meeting and voting in person. If you choose to vote by proxy, please complete, date, sign and return the proxy card in the enclosed postage prepaid envelope. The proxies named in the proxy card will vote your shares as you have instructed. If you sign and return the proxy card without indicating how your votes should be cast, the proxies will vote your shares in favor of each of the proposals contained in this proxy statement, as recommended by our board of directors. Even if you plan to attend the meeting, please complete and mail your proxy card to ensure that your shares are represented at the meeting. If you attend the meeting, you can still revoke your proxy by voting in person. If your shares are held in a brokerage or bank account, you must make arrangements with your broker or bank to vote your shares in person. PROPOSALS TO BE CONSIDERED AT THE ANNUAL MEETING. The principal business expected to be transacted at the meeting, as more fully described below, will be the election of two directors and the ratification of the selection of independent auditors of the Company. QUORUM. A quorum of stockholders is required to transact business at the meeting. A majority of the outstanding shares of common stock entitled to vote, represented at the meeting in person or by proxy, constitutes a quorum for the transaction of business. NUMBER OF VOTES REQUIRED. The number of votes required to approve the proposals that are scheduled to be presented at the meeting is as follows: PROPOSAL REQUIRED VOTE -------- ------------- o Election of two nominees as directors. Each nominee must receive a plurality of the votes cast. o Ratification of auditors. This requires the affirmative vote of a majority of the shares present or represented at the meeting. ABSTENTIONS AND BROKER NON-VOTES. Abstentions and broker non-votes will be counted in determining whether a quorum exists. A broker non-vote occurs when a broker cannot vote a customer's shares registered in the broker's name because the customer did not send the broker instructions on how to vote on the matter and the broker is barred by law or Nasdaq regulations from exercising its discretionary voting authority in the particular matter. In voting on the proposal to ratify the appointment of our auditors, abstentions and broker non-votes will be counted as votes against the proposal. DISCRETIONARY VOTING BY PROXIES ON OTHER MATTERS. Aside from the proposals for the election of directors and the ratification of our selection of auditors, we do not know of any other proposals that may be presented at the 2001 annual meeting. If another matter is properly presented for consideration at the meeting, the persons named in the accompanying proxy card will exercise their discretion in voting on the matter.

HOW YOU MAY REVOKE YOUR PROXY. You may revoke the authority granted by your executed proxy card at any time before we exercise it by filing with our Corporate Secretary, Lynnette C. Fallon, a written revocation or a duly executed proxy card bearing a later date, or voting in person at the meeting. If your shares are held in a brokerage or bank account, you must make arrangements with your broker or bank to revoke your proxy. EXPENSES OF SOLICITATION. We will bear all costs of soliciting proxies. We will upon request reimburse brokers, custodians and fiduciaries for out-of-pocket expenses incurred in forwarding proxy solicitation materials to the beneficial owners of stock held in their names. In addition to solicitations by mail, our directors, officers and employees may solicit proxies from stockholders in person or by other means of communication, including telephone, facsimile and e-mail, without additional remuneration. 2

BOARD OF DIRECTORS AND COMMITTEE MEETINGS Our board of directors held seven meetings during 2000. Our board has standing Audit and Compensation Committees but does not have a Nominating Committee. AUDIT COMMITTEE. The Audit Committee selects and evaluates the Company's independent auditors, reviews the audited financial statements and discusses the adequacy of the Company's internal controls with management and the auditors. The Audit Committee, which met one time during 2000, consists of Messrs. Paul (Chairman), Lautenbach and Tooker. For information about the Audit Committee, see the "Audit Committee Report" below. COMPENSATION COMMITTEE. The Compensation Committee determines the compensation to be paid to our executive officers and also administers our 2000 Stock Plan (the "Stock Plan"). Additionally, the Compensation Committee reviews the management succession plan for the organization. The members of the Compensation Committee are each of the directors other than Mr. Bachman and Ms. Puma. The Compensation Committee and its subcommittee held five meetings in 2000. For information about the Compensation Committee, see the "Compensation Committee Report on Executive Compensation" below. DIRECTOR COMPENSATION DIRECTOR FEES. Other than the Chairman of the Board, our directors do not receive any cash fees. Mr. Hardis, the Chairman of the Board, receives an annual retainer of $200,000, payable quarterly. AUTOMATIC OPTION GRANTS. All non-employee directors of Axcelis are eligible to receive automatic initial and annual grants under our 2000 Stock Plan, provided that while Eaton Corporation was our controlling stockholder, employees of Eaton were ineligible. Under the Stock Plan, at the time of our initial public offering all eligible 6

directors received an initial grant of an option to purchase 24,000 shares. Any director becoming eligible thereafter receives an initial grant of an option for 24,000 shares. In addition, eligible directors will receive options for 12,000 shares once a year, at the meeting of the Board of Directors after July 1 of each year, beginning in 2001. Options are fully exercisable on the 181st day after the date the option is granted, provided the optionee is still a director on that date. The options have a term of ten years and an exercise price equal to the closing price of our common stock on the business day immediately preceding the grant date. The directors who are currently eligible to receive these automatic grants are Messrs. Hardis, Cutler, Lautenbach, Tooker, Paul and Takahashi. At our initial public offering in July 2000, each of Mr. Lautenbach, Mr. Tooker, Mr. Paul and Mr. Takahashi received an option for 24,000 shares with an exercise price of $22.00. Mr. Hardis became eligible to receive an option upon his retirement from Eaton Corporation, and received an option for 24,000 shares with an exercise price of $16.625 in August 2000. Mr. Cutler did not become eligible to receive an automatic grant until January 2001. AUDIT COMMITTEE REPORT An Audit Committee of the Board was formed prior to our initial public offering, composed entirely of non-management directors. The members of the Audit Committee meet the independence and financial sophistication requirements of the Nasdaq Stock Market Rules. Our Board of Directors adopted a charter for the Audit Committee that establishes the responsibilities of the Committee. A copy of this charter is attached as Appendix A to this proxy statement. The Committee schedules four of its meetings to occur after the preparation of quarterly and annual financial statements but prior to the public release of financial results for the period. Two additional meetings are also planned during the year to discuss the Company's internal control systems with the independent auditors and to review the scope and results of the Company's internal audit plans. In 2000, the first quarterly period ending after our initial public offering was the quarter ended September 30, 2000, and therefore only one meeting was held during 2000. The Committee met in January 2001 prior to the release of the 2000 annual financial results and in April 2001 prior to the release of the financial results for the first quarter of 2001. At these meetings, Axcelis' Chief Financial Officer was present, as was our General Counsel and our independent auditors. The Committee's agenda is established by the Committee's chairman, with input from the Company's Chief Financial Officer. Depending on the content of the meeting, the Committee holds private sessions with the Company's independent auditors and, separately, with the Chief Financial Officer, at which candid discussions of financial management, accounting and internal control issues can take place. The Board of Directors engaged Ernst & Young LLP as our independent auditors for 2000. We have discussed with our independent auditors and the Company's Chief Financial Officer overall audit scopes and plans, the results of external audit examinations, evaluations by the auditors of the Company's internal controls and the quality of the Company's financial reporting. Management has reviewed with the Audit Committee the audited 2000 consolidated financial statements in our Form 10-K Annual Report filed with the Securities and Exchange Commission and included in the Annual Report to Stockholders which accompanies this proxy statement. The review included a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements. In its meetings with representatives of the independent auditors, the Committee asks them to address, and discusses their response to, several questions that the Committee believes are particularly relevant to its oversight. These questions include: o Are there any significant accounting judgments made by management in preparing the financial statements that would have been made differently had the auditors themselves prepared and been responsible for the financial statements? 7

o Based on the auditors' experience and their knowledge of the Company, do the Company's financial statements fairly present to investors, with clarity and completeness, the Company's financial position and performance for the reporting period in accordance with generally accepted accounting principles and SEC disclosure requirements? o Based on the auditors' experience and their knowledge of the Company, has the Company implemented internal controls and internal audit procedures that are appropriate for the Company? The Committee believes that, by focusing its discussions with the independent auditors, it can promote a meaningful dialogue that provides a basis for its oversight judgements. The Committee received from the independent auditors their annual written reports covering (1) matters required to be discussed by the auditors with the Committee under Statement on Auditing Standards No. 61, COMMUNICATION WITH AUDIT COMMITTEES and (2) their independence from the Company and its management, which report is made under Independence Standards Board Standard No. 1, INDEPENDENCE DISCUSSIONS WITH AUDIT COMMITTEES. Both reports were discussed with the auditors and management at an Audit Committee meeting, including a discussion of any relationship that may impact the objectivity and independence of our auditors and whether the provision of any non-audit services by the auditors is compatible with maintaining their independence. In performing all of these functions, the Audit Committee acts only in an oversight capacity. Necessarily, in its oversight role, the Committee relies on the work and assurances of the Company's management, which has the primary responsibility for financial statements and reports, and of the independent auditors, who in their report on the audited annual financial statements express an opinion on the conformity of the Company's annual financial statements to generally accepted accounting principles. In reliance on these reviews and discussions and the report of the independent auditors, the Audit Committee has recommended to the Board of Directors, and the Board of Directors has approved, that the audited financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2000, for filing with the Securities and Exchange Commission. The Committee and the Board have also recommended, subject to reconsideration in the absence of shareholder ratification, the selection of the Company's independent auditors for the current year. By the Audit Committee, Philip S. Paul Ned C. Lautenbach Gary L. Tooker 8

EXECUTIVE COMPENSATION COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Compensation Committee of the Board of Directors administers our executive compensation program. Mr. Hardis chairs the Committee, and membership includes Mr. Cutler, Mr. Tooker, Mr. Takahashi, Mr. Paul, and Mr. Lautenbach. In addition, during 2000, we had a subcommittee of the Compensation Committee, the Executive Equity Compensation Committee (the "EECC"), which was composed of all members of the Compensation Committee except Mr. Cutler. The EECC addressed all equity grants to executive officers under the 2000 Stock Plan in order to maintain qualification of such compensation under Internal Revenue Code Section 162(m). This report is submitted by the Committee and addresses the compensation policies for fiscal year 2000 as they affected Mr. Bachman, as Chief Executive Officer, and the top four executive officers other than Mr. Bachman each of whose salary and bonus combined for fiscal year 2000 exceeded $100,000, and who are named in the Summary Compensation Table. This report also covers compensation policies for Cornelius F. Moses, III, who joined the Company in October 2000, but who has been included in the Summary Compensation Table. COMPENSATION PHILOSOPHY During 2000, the Committee was responsible for recommending the compensation package of each existing and newly recruited executive officer. In making decisions regarding executive compensation, the Committee retained the services of PricewaterhouseCoopers, LLP, an independent compensation consulting firm. Additionally, the Committee reviewed benchmarking data obtained from other compensation consultants, including Iquantic, Executive Alliance, and Watson Wyatt Worldwide, to assess the Company's compensation programs. In order to attract, retain and motivate the talented personnel it needs to meet corporate objectives, Axcelis has structured its executive compensation program to provide its employees with total cash compensation (base compensation plus incentive compensation) at the 50th percentile of the compensation paid by other similar sized technology companies if our corporate objectives are achieved. If such objectives are exceeded, Axcelis' compensation program will deliver total compensation at or above the 75th percentile for total compensation paid by our peer group. Bonuses are primarily based on corporate performance, and actual awards will vary year to year according to the Company's overall performance and the individual's impact on that performance. The Company's executive compensation program consists of base salary, cash bonuses and stock option awards. All three components are intended to attract and retain executives and motivate management to meet and exceed Company growth and profitability goals and align management interests with those of our stockholders. In determining the total amount and mix of the compensation package for each executive officer, the Committee members subjectively consider the overall value to the Company of the executive in light of numerous factors such as contributions to the Company's competitive position in the marketplace, individual performance, and the past and expected contribution by the executive toward the achievement of the Company's performance objectives. BASE SALARY The Company's base salaries are structured to be within the median range of salaries paid by similar companies for comparable positions. The Committee believes that the Company's most direct competitors for executive positions are not necessarily the same as the peer companies in the Philadelphia Semiconductor Index, but, depending upon the position, may represent a broader group of similar sized technology companies. The Company actively participates in survey groups facilitated by Iquantic and Executive Alliance. While data from these surveys is categorized by industry type, revenue, and/or geographic locale, the Committee emphasizes the survey cut representing companies with revenues between $300 million and $1 billion, as this most accurately represents companies in a similar position to Axcelis. In establishing the management team in 2000 to prepare for our initial public offering, officer salaries were reviewed and adjusted accordingly based upon survey data provided by PricewaterhouseCoopers. Adjustments were made ranging from 1.1% to 17%. 9

CASH BONUSES Cash bonus targets are set based upon a variety of factors, including market data and anticipated impact of the individual. For the elected officers these targets range from 30% up to 50% in the case of the Chief Executive Officer. For 2000, the Company implemented a cash bonus plan with two components. Because Axcelis was a wholly owned subsidiary of Eaton Corporation until July 2000, the first half of the year was based upon Eaton's earnings per share and a "Balanced Scorecard" for Axcelis divisional performance, including cash flow return on gross capital and several other factors. The second half of the year 2000 was based upon Axcelis's earnings per share and specific "Balanced Scorecard" performance designed to drive longer term, more subjective goals. The Company's performance during 2000 resulted in a 111% average weighted score for the first half of the year and a 200% score for the second half of the year. Individual performance factors may also modify a particular executive's bonus. STOCK OPTIONS The Committee believes it is in the best interests of the Company and its shareholders to grant stock options as the long-term component of executive and key employee compensation. Stock option grants to executive officers and other key employees are intended to bring employee financial interest in line with long-term shareholder value. Stock option awards are at the discretion of the Committee, taking into account the individual's performance and contribution in meeting the goals of the Company. Beginning with our initial public offering in July 2000, stock options were granted to the executive officers and other key employees. The options granted in July 2000 have an exercise price of $22.00, which equals the price to the public in the initial public offering. Subsequent grants to newly hired employees (which includes Mr. Moses) or bonus grants have an exercise price equal to the closing price of the Company's common stock on the day preceding the date of grant. All options granted to executive officers provide for vesting over a period of four years, except in the case of Mr. Bachman, who has a three year vesting schedule, and Ms. Puma, who has a five year vesting schedule. In accordance with an agreement between Eaton and Axcelis, on December 29, 2000, Axcelis employees holding terminating Eaton stock options were provided with replacement options for Axcelis common stock to recognize their past and future contributions. The exercise price of these options was fixed at a price having the same relationship to the closing price of Axcelis common stock on December 29, 2000 as the exercise price of the Eaton option being replaced had to the Eaton market price on that date. The exercisability terms of these grants were carried over from the Eaton options. Mr. Bachman and Ms. Puma voluntarily forfeited their rights to 444,675 replacement stock options in order to reduce the total number of shares granted upon such conversion. Without this forfeiture, the conversion formula in the agreement with Eaton would have resulted in the grant of significantly higher numbers of options than originally contemplated due to an increase in the spread between the Eaton stock price and Axcelis stock price. COMPENSATION OF CHIEF EXECUTIVE OFFICER AND CHIEF OPERATING OFFICER Mr. Bachman was appointed Chief Executive Officer in May 2000. Pursuant to an employment agreement negotiated with the Company, his base salary for this position was established at $600,000 with a target bonus for 2000 equal to 50% of his base salary. As a result of Company performance under the cash bonus plan and individual performance factors, Mr. Bachman's actual bonus for 2000 was $415,830. Ms. Puma was appointed President and Chief Operating Officer in May 2000. Pursuant to an employment agreement negotiated with the Company, her base salary for this position was established at $380,000 with a target bonus for 2000 equal to 45% of her base salary. As a result of Company performance under the cash bonus plan and individual performance factors, Ms. Puma's actual bonus for 2000 was $312,391. 10

As a result of the separation from Eaton Corporation, Ms. Puma and Mr. Bachman lost a number of executive perquisites provided by Eaton. In exchange for these forfeitures, Mr. Bachman and Ms. Puma received one-time payments of $99,999 and $70,000, respectively, less applicable deductions and taxes. Additionally, Eaton assigned to Axcelis a note payable by Ms. Puma of $175,000. Assuming Ms. Puma continues her employment with Axcelis, one third of this obligation will be forgiven annually through 2003. In addition to the cash compensation described above, Mr. Bachman was granted 909,100 non-qualified stock options with an exercise price of $22.00 per share in July 2000. These options will vest 15% in each of July 2001 and 2002 and 70% in July 2003. At December 29, 2000, Mr. Bachman was granted options for an aggregate of 1,011,315 shares at exercise prices from $6.26 to $8.48, reflecting the terms of the Eaton Corporation options being replaced. In July 2000, Ms. Puma was granted 606,100 non-qualified stock options at an exercise price of $22.00 per share. These options will vest 16.5% in each of July 2001 and 2002, 17% in July 2003, 30% in July 2004 and 20% in July 2005. Ms. Puma also received options for an aggregate of 343,033 shares on December 29, 2000 with exercise prices from $7.17 to $10.44, reflecting the terms of Eaton Corporation options being replaced. Ms. Puma also received a restricted stock grant of 47,522 shares of our common stock in December 2000 which replaced a grant of restricted stock from Eaton Corporation which Ms. Puma forfeited as a result of the separation. The forfeiture provision lapses as to 23,761 shares on each of December 31, 2003 and 2004, assuming Ms. Puma's employment continues until those dates. COMPENSATION DEDUCTIBILITY Section 162(m) of the Internal Revenue Code denies a tax deduction to a public corporation for annual compensation in excess of one million dollars paid to its Chief Executive Officer and its four other highest compensated officers. This provision excludes certain types of "performance based compensation" from the compensation subject to the limitation on deductibility. The 2000 Stock Plan contains an individual annual limit on the number of stock options that may be granted under the plan so that the awards will qualify for the exclusion from the limitation on deductibility for performance-based compensation. The Committee will continue to assess the impact of Section 162(m) on its compensation practices and determine what further action, if any, is appropriate. By the Compensation Committee, Stephen R. Hardis, Chairman Alexander M. Cutler Philip S. Paul Ned C. Lautenbach Gary L. Tooker Naoki Takahashi 11

EXECUTIVE AGREEMENTS EMPLOYMENT AGREEMENTS WITH MR. BACHMAN AND MS. PUMA. We have entered into employment agreements with Mr. Bachman and Ms. Puma which were effective as of July 10, 2000. Each agreement provides for a three-year term of employment. Mr. Bachman's agreement can be extended by mutual consent of the parties. Ms. Puma's is self-extending unless one party notifies the other that the agreement will not be extended. The agreements provide that neither employee may compete with us for a period of 12 months after termination of his or her active employment or the remaining term of his or her agreement, whichever is longer, and neither may reveal confidential information for a specified period of time. In the event the agreement and the employee's employment is terminated prior to the end of the term for reasons other than cause, death, disability or voluntary resignation, or, in the case of Mr. Bachman, his agreement is not extended, the employee is entitled to receive all compensation accrued to date, acceleration of vesting of options and other equity rights and base compensation and target bonus, for Mr. Bachman, for the greater of 12 months or the then remaining term or, for Ms. Puma, two years, in each case from the date of termination of employment. 14

Under his agreement, Mr. Bachman's minimum base salary is $600,000 per year and he will have an annual target incentive compensation of 50% of base salary. Ms. Puma's minimum base salary is $380,000 per year and her annual target incentive compensation opportunity is 45% of base salary. Actual incentive compensation for any year may be greater or less if actual performance is greater or less than the target. Base salary and incentive opportunities can be increased by our Board of Directors. The agreements provide that both executives will also participate in the Stock Plan, the defined contribution/401(k) Savings Plan and the welfare benefit plans which we sponsor. CHANGE IN CONTROL AGREEMENTS. We also have entered into change in control agreements with each of our executive officers, including Mr. Bachman and Ms. Puma. These agreements provide that in the event there is both a change in control and a termination of employment within three years of that change in control for reasons other than voluntary resignation, cause, death or disability, the senior officer would be entitled to severance compensation. Under the change in control agreement, a resignation by a senior officer for reasons of a demotion or reduction in compensation, benefits or position is a termination by us and is not a voluntary resignation. If severance compensation is payable, severance consists of (i) a cash payment equal to the sum of (a) incentive compensation for the completed portion of the incentive period and (b) the amount determined by multiplying the employee's then salary and average bonus by three, and (ii) continuation of our medical, life and other welfare benefits for three years. We will also reimburse the employee for the effects, including federal, state and local income tax consequences, of any excise tax due on severance compensation. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION During the fiscal year ended December 31, 2000, the Compensation Committee of the board of directors consisted of Mr. Hardis, Mr. Cutler, Mr. Tooker, Mr. Paul, Mr. Lautenbach and Mr. Takahashi. RELATIONSHIP WITH EATON CORPORATION On June 30, 2000 we entered into a number of agreements with Eaton Corporation, which company then owned all of our outstanding common stock. After our initial public offering in July 2000, Eaton's ownership was reduced to 82% of our outstanding common stock. At December 29, 2000, Eaton distributed to its stockholders all of the shares of common stock held by Eaton at that time. AGREEMENTS RELATED TO THE SEPARATION OF OUR BUSINESS FROM EATON CORPORATION. IN GENERAL. Under these agreements, Eaton transferred to us the assets related to our business and we assumed the actual and contingent liabilities related to our business, except as specifically excluded. The transfer of international assets and assumption of international liabilities was accomplished through agreements entered into between international subsidiaries on various dates preceding December 29, 2000. Eaton did not warrant as to the value of any asset transferred, the existence of any liens or encumbrances or the legal sufficiency of any conveyance of title. Effective as of June 30, 2000, subject to specified exceptions, we released Eaton and its affiliates, agents, successors and assigns, and Eaton released us, and our affiliates, agents, successors and assigns, from any liabilities arising from events occurring on or before June 30, 2000, including events occurring in connection with the activities to implement the separation, our initial public offering and the distribution of our shares by Eaton. We agreed to bear any liability arising from any untrue statement of a material fact or any omission of a material fact in our initial public offering prospectus. EMPLOYEE MATTERS. We entered into an employee matters agreement with Eaton to allocate assets, liabilities and responsibilities relating to our current and former employees and their participation in the benefit plans. All of our eligible employees continued to participate in Eaton benefit plans until December 29, 2000. The assets relating to Eaton's qualified employee benefit plans have been transferred to our related plans. The employee matters agreement also required us to assume all Eaton options held by our employees as of December 29, 2000. This was done in accordance with a conversion formula set forth in the agreement under which employees received Axcelis options which had the same intrinsic value as Eaton options which terminated at the end of 2000 due to the separation. 15

Both Eaton and Axcelis agreed not to directly solicit or recruit employees of the other without the other's consent until December 29, 2002, except in the case of general recruitment efforts carried out through public or general solicitation or where the solicitation is employee-initiated. TAX MATTERS. We entered into a tax sharing and indemnification agreement with Eaton that allocates responsibilities and liabilities for tax matters. The agreement requires us to pay Eaton for our allocable share of any taxes due with respect to consolidated, combined or unitary tax returns that Eaton files for all periods between December 31, 1999 and December 29, 2000. This agreement also provides that until December 29, 2002, Axcelis will not, without Eaton's prior written consent, liquidate, merge or consolidate with any other person, or enter into any transaction or make any change in our equity structure that may cause the distribution of our shares by Eaton to be treated as part of a plan pursuant to which one or more persons acquire a 50 percent or greater interest in our stock. The agreement also requires us to indemnify Eaton for certain taxes (including interest and penalties) that would not have been payable but for the breach by us of any representation, warranty or obligation. REAL ESTATE. Our real estate matters agreement describes the manner in which Eaton transferred to us, or shares with us, various leased and owned properties. Under this agreement, we acquired title to our properties in Beverly, Massachusetts, and leases to properties in other locations. We have agreed to indemnify Eaton and its affiliates, agents, successors and assigns from all liabilities arising from environmental conditions occurring, present at, caused by or related to any of our properties or operations before June 30, 2000 as to any of the facilities transferred to us, and arising from environmental conditions occurring, present at, caused by or related to any of our properties or operations on or after that date. INSURANCE MATTERS. We also have an indemnification and insurance matters agreement with Eaton, which contains provisions governing our insurance coverage from June 30, 2000 until December 29, 2000. During that time, Eaton maintained insurance coverage on our behalf. In general, we agree to reimburse Eaton for premium expenses related to insurance coverage during the period. TRADEMARK LICENSE. Eaton granted us a royalty free, worldwide license to use the name "EATON" as a trademark for photostabilizers and ion implantation equipment. The license is for a period of two years and thereafter is terminable at will by Eaton with six months prior notice to us, or immediately for cause. INFORMATION EXCHANGE. Both Eaton and we have agreed to share information relating to governmental, accounting, contractual and other similar requirements of our ongoing businesses, unless the sharing would be commercially detrimental. ACCOUNTING AND AUDITING PRACTICES. In light of the fact that Eaton will be consolidating and reporting on our results of operations and financial position through December 29, 2000, the transition agreements contain a number of covenants limiting our ability to change accounting policies or principles relating to that period and otherwise facilitating Eaton's reporting requirements. EXPENSE ALLOCATION. We agreed to bear the costs and expenses associated with the separation of businesses and with our initial public offering. Eaton agreed to bear the costs and expenses associated with their distribution of our shares. We will each bear our own internal costs incurred in consummating these transactions. Any nonrecurring costs and expenses that are not allocated in the agreement are the responsibility of the party that incurs the costs and expenses. DISPUTE RESOLUTION. We have agreed with Eaton to resolve any dispute first through good faith negotiation, then non-binding mediation, followed by binding arbitration, unless the failure to initiate litigation would cause serious and irreparable injury to one of the parties or to others. TRANSITIONAL SERVICES AGREEMENT The transitional services agreement provides for the delivery of transitional services by Eaton to us on an interim basis, generally for not longer than December 31, 2001. The agreement provides for services, systems and support for our operations, including voice and data transmissions and other data-related operations, accounts 16

receivables, accounts payable, fixed assets, payroll, general accounting, financial accounting consolidations, cash management, human resources, legal and real estate. Services are generally priced at cost prior to Eaton's divestiture on December 29, 2000 and thereafter at cost plus our additional fee. We paid Eaton approximately $5.5 million for transitional services provided during 2000. RELATIONSHIP WITH SUMITOMO EATON NOVA Mr. Takahashi, one of our directors, is a Director, Senior Vice President and General Manger of the Precision Products Division of Sumitomo Heavy Industries, Ltd. We have a joint venture with Sumitomo Heavy Industries, Ltd., known as Sumitomo Eaton Nova, or SEN. SEN, of which we own 50% of the equity, provides us with additional manufacturing capacity for our ion implant products and local access to the Japanese semiconductor equipment market. Under our arrangements with Sumitomo Heavy Industries, Ltd., our ion implant products may be sold in Japan only through the joint venture. SEN may sell its products outside Japan only with our consent and through us as exclusive distributor. There are isolated sales of our equipment into Japan to our non-Japanese customers and isolated sales of SEN equipment outside of Japan primarily to its Japanese customers and their joint ventures. SEN manufactures ion implantation equipment at its Toyo, Japan location under the license from us described below. From time to time, we sell ion implantation equipment and other products to SEN. In 2000, our net sales of products to SEN amounted to $11.9 million. As part of the joint venture arrangement, we have entered into a separate license agreement with SEN, last renewed in 1996, under which we have granted SEN an exclusive license in Japan to use our current and future ion implantation technology and to manufacture, use and sell products using our current and future ion implantation patents. We have also granted SEN a non-exclusive license to sell ion implantation products outside of Japan, subject to the terms of an Export Sales Agreement under which we are exclusive marketing agent. The license agreement expires on December 31, 2004 and is automatically renewable for successive five year periods unless either party has provided one year's prior notice of termination. We also have a trademark license agreement with SEN which will terminate on December 31, 2004 and which obligates SEN to pay us a 0.5% royalty on net sales. In 2000, we recognized royalty income from SEN under these license agreements of approximately $13.5 million. 17

PROPOSAL 2: RATIFICATION OF THE APPOINTMENT OF INDEPENDENT AUDITORS Upon the recommendation of its Audit Committee, the Board of Directors has appointed the accounting firm of Ernst & Young LLP as independent auditors to conduct the annual audit of Axcelis' books and records for 2001 and is seeking stockholder ratification of the appointment. Ernst & Young LLP is an internationally recognized public accounting firm that audited the Company's books in 2000 and which the Audit Committee believes is well qualified to continue. The submission of this matter to the stockholders at the annual meeting is not required by law or by our bylaws. The Board of Directors is nevertheless submitting it to the shareholders to ascertain their views. If this proposal is not approved at the annual meeting by the affirmative vote of holders of a majority of the shares present or represented at the meeting, the Board intends to reconsider its appointment of Ernst & Young LLP as independent auditors. The Board may retain the firm for 2001 notwithstanding a negative stockholder vote. Representatives of Ernst & Young are expected to attend the annual meeting and be available to respond to appropriate questions. They will also have the opportunity to make a statement if they desire. The fees for services provided by Ernst & Young to the Company in 2000 were as follows: AUDIT FEES .............................. $250,450 AUDIT RELATED FEES ...................... $76,314 ALL OTHER FEES .......................... $83,925 The Board of Directors recommends a vote for ratification of the appointment of Ernst & Young LLP. CERTAIN TRANSACTIONS Three members of our board of directors serve as directors and/or officers of Eaton Corporation.

Approve the fees to be paid to the independent auditor for audit services. 9. Obtain annually a formal written statement from the independent auditor delineating all relationships between the auditor and the Company, consistent with Independence Standards Board Standard No. 1, and discuss such statement with the auditor and, if so determined by the Audit Committee, recommend that the Board take appropriate action to satisfy itself of the independence of the auditor. 10.
