AMERICAN TECHNICAL CERAMICS CORP.

PROXY STATEMENT

This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of American Technical Ceramics Corp., a Delaware corporation (the "Company"), to be voted at the Annual Meeting of Stockholders and any adjournment or postponement thereof (the "Annual Meeting"). The Annual Meeting will be held at 1:00 p.m., Eastern Standard Time, on Wednesday, November 17, 2004, at the Company's facility at 2201 Corporate Square Boulevard, Jacksonville, Florida 32216. The principal executive offices of the Company are located at 17 Stepar Place, Huntington Station, New York 11746. It is expected that this Proxy Statement and the accompanying proxy card will first be mailed or delivered to stockholders entitled to notice of, and to vote at, the Annual Meeting on or about October 22, 2004.

VOTING SECURITIES AND VOTING RIGHTS

Only holders of record of the Company's Common Stock, par value $0.01 per share (the "Common Stock"), at the close of business on October 8, 2004, will be entitled to notice of, and to vote at, the Annual Meeting. As of October 8, 2004, there were 8,315,918 shares of Common Stock issued and outstanding. A majority of the outstanding shares of Common Stock present in person or by proxy shall constitute a quorum at the Annual Meeting. Each outstanding share of Common Stock is entitled to one vote on all matters, which vote may be given in person or by proxy duly authorized in writing. There are no cumulative voting rights.

All proxies received pursuant to this solicitation will be voted, and, where a choice is specified as to the proposals described in the foregoing Notice of Annual Meeting of Stockholders, they will be voted in accordance with that specification. If no specific instructions are given with respect to the matters to be acted upon, the shares of Common Stock represented by a signed proxy will be voted FOR all of the Board's nominees for director, FOR the proposal to ratify the appointment of KPMG LLP as the independent public accountants to audit the Company's consolidated financial statements for the fiscal year ending June 30, 2005, and in accordance with the proxy holders' best judgment as to any other matters as may properly come before the Annual Meeting. Stockholders who have executed proxies may revoke them at any time before they are voted by submitting a later dated proxy or by written notice delivered to the Secretary of the Company. Personal attendance at the Annual Meeting without submitting a later dated proxy or a written notice of revocation to the Secretary shall not serve to revoke any proxy.

The affirmative vote of the holders of a majority of the shares of Common Stock present at the Annual Meeting in person or by proxy and entitled to vote is necessary for the election of directors and the ratification of KPMG LLP as the Company's independent public accountants to audit the Company's consolidated financial statements for the fiscal year ending June 30, 2005. Accordingly, an abstention is treated as a share present or represented and entitled to vote and is the equivalent of a vote against the election of any nominee for election to the Board of Directors of the Company or the proposal to ratify the appointment of KPMG LLP. If stockholders hold their shares of Common Stock through a broker, bank or representative, generally the broker or representative may only vote the Common Stock that it holds in accordance with the stockholder's instructions. However, if it has not timely received such instructions, the broker or representative may vote on certain matters for which it has discretionary voting authority. If the broker or representative cannot vote on a particular matter because it does not have discretionary voting authority, this is a "broker non-vote" on that matter. For purposes of voting, broker non-votes will not be considered present at the Annual Meeting and, therefore, will not be considered in determining the presence of a quorum. Broker non-votes will have no effect on the outcome of the vote for the election of directors or the ratification of KPMG LLP as the Company's independent accountants.

As of October 8, 2004, Victor Insetta, the President, Chief Executive Officer and a director of the Company, owned 4,449,130 shares of Common Stock, representing approximately 53.5% of the issued and outstanding shares of Common Stock. His shareholdings are sufficient to assure election of the nominees for election as directors as set forth herein, to ratify the appointment of KPMG LLP as the independent public accountants to audit the Company's consolidated financial statements for the fiscal year ending June 30, 2005 and to take action on any other matters that may properly come before the Annual Meeting.

The Company will bear the entire cost of the solicitation of proxies by the Board of Directors. Proxies will be solicited by mail, and may be solicited personally by telephone or facsimile or electronic transmission, by directors, officers and regular employees of the Company, without additional remuneration.

There are no family relationships between or among any directors or executive officers of the Company. See footnotes (2) and (3) to the table under the caption "Security Ownership of Certain Beneficial Owners and Management" for information concerning agreements among certain stockholders as to the election of directors. See also "Certain Relationships and Related Transactions" for information concerning the lease of certain real property owned by entities in which Mr. Insetta has an interest.

Board Meetings; Committees of the Board of Directors

Meeting Attendance.    During the fiscal year ended June 30, 2004, the Board of Directors held six meetings. All of the meetings were attended by all of the directors, with the exception of Mr. Litt who was unable to attend one meeting.

Audit Committee.    The Board of Directors has a separately-designated standing Audit Committee established in accordance with section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The Audit Committee, which held nine formal meetings and communicated informally several times during the fiscal year ended June 30, 2004, currently consists of Messrs. Garrard, Spence, Volpe and Bacharach. All of the members of the Audit Committee are independent as defined in Section 121(A) of the American Stock Exchange's listing standards. The authority of the Audit Committee is set forth in more detail in its Charter, which was adopted by the Board of Directors in fiscal year 2003. The Audit Committee's primary function is to assist the Board of Directors in fulfilling its oversight responsibilities by reviewing the financial information which will be provided to stockholders and others, the systems of internal controls which management and the Board of Directors have established, and the audit process. In addition, the Audit Committee provides an open avenue of communication between the independent registered public accountants, financial management and the Board of Directors. Messrs. Garrard and Volpe attended all of the meetings held by the Audit Committee during the fiscal year ended June 30, 2004. Messrs. Spence and Bacharach each were unable to attend one meeting held during the fiscal year. Please see the Report of the Audit Committee set forth elsewhere in this Proxy Statement.

The Board of Directors has determined that Messrs. Garrard and Volpe are "audit committee financial experts" as defined in Item 401(h) of Regulation S-K under the Exchange Act and are also "independent" as that term is used in Item 7(d)(3)(iv) of Schedule 14A under the Exchange Act.

Compensation Committee.    The Compensation Committee, which currently consists of Messrs. Garrard, Spence, Volpe and Bacharach, is authorized, subject to the Certificate of Incorporation and By-Laws of the Company and the Delaware General Corporation Law, to exercise all power and authority of the Board of Directors with respect to the compensation of employees of the Company. The authority of the Compensation Committee is set forth in more detail in a written Charter adopted by the Company's Board of Directors. The Compensation Committee held three formal meetings during the fiscal year ended June 30, 2004, which all of the members attended.

Nominating Committee.    Because more than 50% of the voting power of the Company is owned by Victor Insetta, the Company qualifies as, and has elected to be treated as, a "controlled company" under the rules of the American Stock Exchange. A controlled company is exempt from several of the American Stock Exchange listing requirements, including, among others, the requirements that (i) the Board of Directors be comprised of a majority of independent directors, (ii) the compensation of executive officers be determined, or recommended to the Board of Directors for determination, by a compensation committee comprised entirely of independent directors or by a majority of the independent directors on the Board of Directors, and (iii) nominees for membership on the Board of Directors be selected, or recommended for selection by the Board of Directors, by a nominating committee comprised entirely of independent directors or by a majority of the independent directors on the Board of Directors. Notwithstanding this exemption, a majority of the members of the Company's Board of Directors satisfy the American Stock Exchange's standards for independence. Moreover, the Board has established a Compensation Committee which is comprised entirely of independent directors.

---

The Board does not have a separate Nominating Committee. The Board is currently comprised of a majority of independent directors. Two of the members of the Board qualify as financial experts, two are industry experts and two (including one of the industry experts) are former employees of the Company and, accordingly, are familiar with its operations. The Board believes that, in light of the size of the Company and the qualifications and complementary strengths of the members of the Board, the current size of the Board is appropriate. If the Board determines that it is in the Company's best interest to expand the Board, the entire Board would oversee the identification and consideration of candidates for membership.

Communications with the Board of Directors

The Board of Directors recommends that stockholders initiate any communications with the Board in writing and send them in care of the Secretary of the Company. Stockholders can send communications by e-mail to kkelly@atceramics.com, by fax to (631) 622-4610 or by mail to Kathleen M. Kelly, Secretary, American Technical Ceramics Corp., 17 Stepar Place, Huntington Station, New York 11746. This centralized process will assist the Board of Directors in reviewing and responding to stockholder communications in an appropriate manner. The name of any specific intended Board recipient should be noted in the communication. The Board has instructed the Secretary to forward such correspondence only to the intended recipients; however, the Board has also instructed the Secretary, prior to forwarding any correspondence, to review such correspondence and, in her discretion, not to forward certain items if they are deemed of a commercial or frivolous nature or otherwise inappropriate for the Board's consideration. In such cases, some of that correspondence may be forwarded elsewhere in the Company for review and possible response.

Compensation of Directors

Each non-employee director of the Company receives an annual retainer of $10,000 plus a fee of $1,000 plus expenses for each meeting, excluding teleconference meetings, of the Board of Directors and, if a member of a Committee, each Committee meeting not held on the same day that a meeting of the Board of Directors or another Committee of the Board is held, that he attends. In addition, provided he is serving as a director of the Company on June 30th of the applicable year, each non-employee director is granted options under the Company's stock option plans to purchase 5,000 shares of Common Stock at an exercise price equal to the closing sale price of the Company's Common Stock on the American Stock Exchange on such June 30th. The term of each option is ten years from the date of grant. The options vest in four equal installments over the first four years of their term.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act, requires the Company's officers, directors and persons who own beneficially more than ten percent of the Company's Common Stock to file with the Securities and Exchange Commission initial reports of beneficial ownership and reports of changes in their beneficial ownership of Common Stock. Officers, directors and persons owning more than ten percent of the Common Stock are required to furnish the Company with copies of all such reports. Based solely on a review of copies of such reports furnished to the Company, the Company believes that, during the fiscal year ended June 30, 2004, the only deviations from the Section 16(a) filing requirements applicable to its officers, directors and persons owning beneficially more than ten percent of the Common Stock were that, Messrs. Monsorno and Volpe inadvertently failed to timely file Statements of Change in Beneficial Ownership on Form 4 or an Annual Statement of Beneficial Ownership on Form 5 with respect to gifts of stock to family members. Each of them has since filed an Annual Statement of Beneficial Ownership on Form 5 reflecting these gifts.

Pursuant to its terms, the agreement is automatically renewed for successive one-year periods beginning on March 1 of each year unless either party gives written notice of his or its election to terminate the agreement at least 120 days prior to such date.

Pursuant to the agreement, Mr. Insetta was paid base compensation for the fiscal year ended June 30, 2004 of $350,000. The agreement provides for further increases in Mr. Insetta's base salary by the Board of Directors from time to time in its sole discretion. (Mr. Insetta's base salary was increased by the Compensation Committee of the Board of Directors, effective June 1, 2003, from $323,000 per annum to $350,000 per annum.) The agreement also provides that, as additional annual compensation, Mr. Insetta is entitled to an amount equal to 2.5% of the Company's net income (before such incentive compensation and before income taxes). The Company, at its option, may pay the additional annual compensation in stock, cash or a combination thereof, subject to certain limitations. No additional compensation was paid to Mr. Insetta for fiscal years 2002 and 2003. For the fiscal year ended June 30, 2004, the Company elected to pay all of Mr. Insetta's additional compensation in cash. See "Executive Compensation — Summary Compensation Table."

The agreement further provides, among other things, that if there is a change of control of the Company or if Mr. Insetta's employment is terminated prior to the scheduled expiration date other than for cause (as defined in the agreement), death, disability, or voluntary termination apart from a change of control, the Company is required to pay to Mr. Insetta, in a lump sum, an amount equal to the greater of (i) all of the compensation due to Mr. Insetta under the agreement through the end of the then existing term of the agreement, or (ii) three times Mr. Insetta's average annual compensation under the agreement during the five most recent fiscal years prior to the fiscal year in which the termination took place as calculated in accordance with the Section 280G of the Internal Revenue Code of 1986, as amended (the "Code"). In addition, if Mr. Insetta voluntarily terminates his employment with the Company, for a period equal to the lesser of the remaining term of the agreement or one year, Mr. Insetta has agreed that he will not, directly or indirectly, solicit those persons or entities who are customers of the Company on the effective date of his termination of employment for the purpose of purchasing multi-layer capacitors; provided, however, that the foregoing restriction shall not apply if Mr. Insetta terminates his employment because of a change of control of the Company. In addition, Mr. Insetta has agreed that, for a period of one year following the termination of his employment (other than termination by the Company without cause), he will not divulge to any person any information which is actually held in confidence by the Company, subject, however, to certain conditions, including the Company having performed, and continuing to perform, its obligations under the agreement.

The Company presently maintains a term life insurance policy in the aggregate amount of $4,000,000 on the life of Mr. Insetta. The Company is named as the beneficiary of this policy.

Stephen Beyel

In April 2003, the Company entered into a three-year employment agreement with Stephen Beyel, the Company's Senior Vice President — Sales. The agreement provides for base compensation of $160,000, plus additional compensation based upon specific performance measures (as defined in the agreement). See "Executive Compensation — Bonus Programs."

Mr. Beyel's employment with the Company was terminated in September 2004. Pursuant to the agreement, provided he continues to abide by certain obligations contained in the agreement, Mr. Beyel is entitled to receive his base salary for a period of one year from the date of termination.

Richard Monsorno

In October 2003, the Company entered into a three-year employment agreement with Richard Monsorno, the Company's Senior Vice President — Technology. The agreement provides for base compensation of $208,428, subject to increase in the discretion of the Board Directors. In addition, Mr. Monsorno is entitled to participate in the Company's Officers' Bonus Plan. See "Executive Compensation — Bonus Programs."

The agreement may be terminated by the Company at any time. If the agreement is terminated by the Company for reasons other than cause, or if Mr. Monsorno terminated his employment (provided he continues to abide by certain obligations contained in the agreement), Mr. Monsorno would be entitled to receive his base salary for 15 months from the date of termination, the Company would continue to provide medical coverage for Mr. Monsorno and his family for a period of 18 months and Mr. Monsorno would be entitled to exercise all vested stock options for a period of one year following termination.

Judah Wolf

In March 2002, the Company entered into a new employment agreement with Judah Wolf, the Company's Senior Vice President — Thin Film Products, effective January 1, 2002. The agreement will expire December 31, 2005, and will automatically renew for successive one year periods unless either party gives written notice of his or its election to terminate the agreement at least 60 days prior to the date the agreement is scheduled to expire.

10

---

The agreement provides for annual base compensation of $125,000, increasing by 8% in each successive year of the agreement. In addition, Mr. Wolf receives a quarterly incentive bonus equal to 3% of the Thin Film Profit Contribution (as defined in the agreement). Mr. Wolf is also entitled to participate in the Company's Officers' Bonus Plan. Any amount to which he would be entitled under such plan shall be reduced by an amount equal to one half of one percent of the Thin Film Profit Contribution. See "Executive Compensation — Bonus Programs."

The agreement may be terminated by the Company at any time. If the agreement is terminated for reasons other than disability or cause, provided he continues to abide by certain obligations contained in the agreement, Mr. Wolf is entitled to receive his base salary for the remainder of term of the agreement and to exercise all vested stock options for a period of one year following termination.

David Ott

In January 2004, the Company entered into a two-year employment agreement with David Ott, the Company's Senior Vice President — New York Operations. The agreement provides for base compensation of $165,500, subject to increase in the discretion of the Board of Directors. In April 2004, the annual compensation was increased to $200,000 in connection with a promotion. In addition, Mr. Ott is entitled to participate in the Company's Officers' Bonus Plan. See "Executive Compensation — Bonus Programs."

The agreement may be terminated by the Company at any time. If the agreement is terminated for reasons other than disability or cause, provided he continues to abide by certain obligations contained in the agreement, Mr. Ott is entitled to receive his base salary for a period of one year from the date of termination.

Severance Agreements

In November 2003, the Company entered into three separate severance agreements with three executive officers. If the officer is terminated by the Company during the term of the agreement other than for cause (as defined in the agreement), (i) the officer will be entitled to receive his or her base salary for a period of months equal to the number of years the employee has been an executive officer plus three months up to a maximum of 15 months, (ii) the Company shall continue to provide family medical coverage for the severance period, and (iii) all exercisable options may be exercised during the lesser of the severance period or the expiration of the options.

Consulting Agreement

Stuart Litt

In October 2000, upon his retirement as Senior Vice President — Operations of the Company, the Company entered into a consulting agreement with Stuart P. Litt. Mr. Litt remains on the Board of Directors of the Company. The agreement commenced January 1, 2001 and expired on December 31, 2003.

In January 2004, the Company entered into a new consulting agreement with Mr. Litt. Under the agreement, Mr. Litt provides advisory and consulting services to the Company for a maximum of fifteen full days in each calendar quarter. The Company pays Mr. Litt the sum of $2,000 for each full day he provides services to the Company. The Company is also required to reimburse Mr. Litt for reasonable and necessary expenses incurred in providing his consulting services.

Bonus Programs

The Company has a bonus program for eligible executive officers pursuant to which each such officer is eligible to receive quarterly cash bonuses equal to a percentage of the Company's net income (before such bonuses and before income tax) as determined by the Board. In the fiscal year ended June 30, 2004, the percentages ranged from one half of one percent to three quarters of one percent. In the event of a net loss in any quarter, the amount of such net loss is applied to reduce the bonus payable in future quarters in that fiscal year. In the fiscal year ended June 30, 2004, the Company paid bonuses aggregating $59,517 under this program, including bonus awards of $14,935 and $11,146 to Messrs. Monsorno and Ott, respectively. See "Executive Compensation — Summary Compensation Table."

Mr. Beyel was eligible to receive a quarterly cash bonus based upon achievement of certain quotas for order bookings and profit. In the fiscal year ended June 30, 2004, the Company paid Mr. Beyel bonuses aggregating $123,996. See "Executive Compensation — Summary Compensation Table."

Mr. Wolf participates in a modified version of this bonus program as stated in his employment agreement. In the fiscal year ended June 30, 2004, the Company paid Mr. Wolf bonuses aggregating $56,774. See "Employment Agreements — Judah Wolf" and "Executive Compensation — Summary Compensation Table."

Compensation Committee Interlocks and Insider Participation

On November 21, 2002, the Board of Directors voted to reestablish the Compensation Committee which had been disbanded on November 15, 2000. The Board of Directors as a whole had deliberated on matters of compensation between the time the Committee was disbanded and the time it was reestablished. No officer who serves as a director of the Company participated in matters involving the evaluation of his own performance or the setting of his own compensation. See "Executive Compensation — Report on Executive Compensation." No officer who serves as a director of the Company served on the board of directors of any other company.

Report on Executive Compensation

Notwithstanding anything to the contrary in any of the Company's previous or future filings under the Securities Act of 1933, as amended, (the "Securities Act"), or the Exchange Act that might incorporate this Proxy Statement by reference into future filings with the Securities and Exchange Commission ("SEC"), in whole or in part, the following report shall not be incorporated by reference into any such filing.

For many years, the full Board of Directors has been responsible for making decisions with respect to employee compensation issues. In November 2002, the Board of Directors reestablished the Compensation Committee. See "Executive Compensation — Compensation Committee Interlocks and Insider Participation." No officer who serves as a director of the Company participated in matters involving the evaluation of his own performance or the setting of his own compensation.

The Company seeks to establish compensation plans and policies which are designed to (i) attract and retain highly qualified employees at all levels, (ii) provide rewards that are closely linked to the Company's performance, and (iii) align the interests of the Company's employees with those of its stockholders through stock ownership. The Company monitors the compensation paid to various levels of employees on both a geographic and industry basis. Moreover, the Company has established bonus compensation programs for virtually all levels of employees pursuant to which they are rewarded based upon the overall profitability of the Company. Finally, the Company has over the past several years awarded stock bonuses and stock options to several executive officers and supervisory employees in order to reward them for their efforts on behalf of the Company and to provide them with a direct stake in the Company's future. In April 1997, the Board adopted the 1997 Stock Option Plan in order to expand the universe of individuals who are important to the Company's success who may be eligible for stock-based compensation. Having granted options for all of the shares authorized for issuance under such plan, in April 2000, the Board adopted the 2000 Incentive Stock Plan in order to enable the Company to continue to utilize stock awards and options as a means of attracting and retaining employees important to the Company's success.

The base salary of Victor Insetta, the Company's President and Chief Executive Officer, for fiscal year 2004 was based principally upon his rights under his employment agreement. The agreement, which was entered into in 1985 and has been amended several times, provided for a minimum base salary at the rate of $323,162 from March 1, 2000 until June 1, 2003, when Mr. Insetta's minimum base salary was increased to $350,000 per annum. The Compensation Committee believed that this increase was warranted in light of Mr. Insetta's important contributions to the Company over the past several years (including managing the Company well in a challenging business environment and furthering the Company's progress toward its long-term objectives) and because Mr. Insetta's salary had not been reviewed in over three years. More over, this increase is consistent with cost of living increases granted to virtually all employees of the Company over the period since Mr. Insetta's salary was last reviewed.

Mr. Insetta's employment agreement also entitles him to annual incentive compensation of two and a half percent of the Company's net income (before such incentive compensation and before income taxes). The Compensation Committee believes that it is appropriate for the compensation of the Chief Executive Officer of the Company to be based, in substantial part, on the Company's overall performance. Mr. Insetta's employment agreement allows the Company to pay Mr. Insetta's annual incentive compensation in cash, Common Stock or a combination thereof. The determination of the manner of payment is made each year by the Board of Directors, in its sole discretion, subject to certain limitations.

13

---

Mr. Insetta's received no incentive compensation in respect of fiscal years 2002 and 2003. For the fiscal year ended 2004, 100% of Mr. Insetta's annual incentive compensation was paid in cash. The Board believed this was appropriate in light of the Company's cash position and the current level of Mr. Insetta's stock ownership in the Company.

Notwithstanding anything to the contrary in any of the Company's previous or future filings under the Securities Act or the Exchange Act that might incorporate this Proxy Statement by reference into future filings with the SEC, in whole or in part, the following report shall not be deemed to be incorporated by reference into any such filing.

In accordance with its written Charter, the Audit Committee assists the Board in fulfilling its oversight responsibilities with respect to the accounting, auditing, financial reporting and internal control functions of the Company and its subsidiaries.

Management of the Company is responsible for the preparation, presentation and integrity of the Company's financial statements, and for maintaining appropriate accounting and financial reporting principles and policies and internal controls and procedures designed to provide reasonable assurance of compliance with accounting standards and applicable laws and regulations. The independent accountants are responsible for planning and carrying out an audit in accordance with generally accepted auditing standards and expressing an opinion as to the conformity of the financial statements with generally accepted accounting principles.

In the performance of its oversight function, the Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended June 30, 2004 with management and with KPMG LLP, the Company's independent public accountants. The Audit Committee has also received from KPMG LLP a report pursuant to Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended, and has discussed the matters referred to in such report with KPMG LLP.

The Audit Committee has further discussed with KPMG LLP its independence.

The Audit Committee's considerations and discussions referred to above do not assure that the audit of the Company's financial statements for the fiscal year ended June 30, 2004 has been carried out in accordance with generally accepted auditing standards, that the financial statements are presented in accordance with generally accepted accounting principles or that the Company's accountants are in fact "independent".

Based upon the review and discussions described above, and subject to the limitations on the role and responsibilities of the Audit Committee referred to above and in its Charter, the Audit Committee has recommended to the Board that the audited financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2004 for filing with the SEC.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Related Party Leases

The Company presently leases certain real property from entities controlled by its President, Chief Executive Officer and principal stockholder, Victor Insetta. In the case of each such lease, the Company has periodically obtained appraisal letters indicating that the fixed rentals in effect did not exceed fair market rentals in the area. The Company does not intend to lease any additional real property from Mr. Insetta or entities controlled by him other than renewals of existing leases and improvements and new construction that may be made to existing leased properties.

Florida Facility

The Company, through its wholly-owned subsidiary, American Technical Ceramics (Florida), Inc. ("ATC-Florida"), leases an administrative office, manufacturing and research and development complex located in Jacksonville, Florida (the "Jacksonville Facility") from V.P.I. Properties Associates, a partnership controlled by Mr. Insetta ("VPI"), under a capital lease. At June 30, 2004, the Jacksonville Facility had an aggregate cost of $5,104,000 and a net book value of $2,332,000. The lease is for a period of 30 years, was capitalized using an interest rate of 10.5% and expires on September 30, 2010. The lease currently provides for base rent of approximately $756,000 per annum (approximately $63,000 per month). The fixed rental is adjusted upward (but not downward) annually based upon the increase, if any, in the Consumer Price Index for all Urban Consumers for the last reported month available on August 1^st of each year during the lease compared to such index for the same month in the previous calendar year. In no event may the monthly payments in respect of fixed rent under the lease be less than the monthly payments of principal and interest due and payable by VPI in connection with the financing for the Jacksonville Facility. ATC-Florida is also obligated to pay all expenses arising in connection with the Jacksonville Facility, including all real estate taxes, assessments, insurance, utilities and repairs. The lease also provides for increases to the base rent in connection with any new construction at the Jacksonville Facility. Under the lease, upon any new construction being placed into use, the base rental is subject to increase to the fair market rental of the Jacksonville Facility, including the new construction.

The Company, through ATC-Florida, has the right at the end of the lease term to purchase the Jacksonville Facility at its fair market value and has a right of first offer to purchase the Jacksonville Facility if VPI elects to sell it in the interim.

In the fiscal year ended June 30, 2004, the aggregate rental paid by ATC-Florida under this lease was $781,592. In addition, ATC-Florida incurred expenses of $340,219 for real estate taxes, $370,828 for utilities and $49,654 for leasehold improvements.

New York Property

Since July 1976, the Company has leased from Mr. Insetta the land and building at 15 Stepar Place, Huntington Station, New York (the "New York Property"). The lease for the New York Property, which was amended and restated as of September 25, 1998, expired December 31, 2001. The Company continued to lease the New York Property on a month-to-month basis under the terms in effect when the lease expired until September 1, 2002 when the Company entered into a new lease for the New York Property with Stepar Leasing LLC, a limited liability company owned by Mr. Insetta to which he had transferred ownership of the New York Property ("Stepar Leasing"). Under the new lease, the Company currently pays annual base rent of $416,000, subject to annual increases based upon increases in the consumer price index. The lease expires in September 2007, subject to four five-year renewal options.

17

---

The Company is also responsible for payment of all real estate taxes and all utilities and repairs relating to the property. During the fiscal year ended June 30, 2004, the total amount of rent paid by the Company for this facility was $413,157. In addition, the Company incurred expenses of $75,361 for real estate taxes, $266,041 for utilities and $55,050 for leasehold improvements.

The Company has the option to purchase the New York Property at any time during the lease at its fair market value and a right of first offer if Stepar Leasing elects to sell it in the interim.

CODE OF CONDUCT AND ETHICS

The Company has adopted a corporate code of conduct and ethics that applies to all of its employees, including its chief executive officer and chief financial and accounting officers. The text of the corporate code of conduct and ethics is available on the Company's website at http://www.atceramics.com. Disclosure regarding any amendments to, or waivers from, provisions of the corporate code of conduct and ethics that apply to the Company's directors or principal executive and financial officers will be included in a Current Report on Form 8-K within four business days following the date of the amendment or waiver, unless website posting of such amendments or waivers is then permitted by the rules of the American Stock Exchange.

PROPOSAL 2

RATIFICATION OF INDEPENDENT PUBLIC ACCOUNTANTS

KPMG LLP, the independent public accountants who have audited the Company's financial statements for the past fifteen years, have been appointed by the Audit Committee of the Board of Directors of the Company to audit the Company's consolidated financial statements for the fiscal year ending June 30, 2005. The Audit Committee believes that the selection of an independent public accountant to audit the financial statements of the Company prepared by management is an appropriate matter for stockholder consideration. If the stockholders do not ratify the selection of KPMG LLP, the Audit Committee will consider the selection of another firm of independent certified public accountants to audit the Company's consolidated financial statements for the fiscal year ending June 30, 2005. Representatives of KPMG LLP are expected to be present at the Annual Meeting and, if present, will have an opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions.

Principal Accountant Fees and Services

The following table sets forth fees billed by KPMG LLP for the last two fiscal years ended June 30,:

				2003				2004
Audit Fees				$	292,840			$	305,140
Audit Related Fees (1)					33,350				35,500
Tax Fees (2)					108,340				77,850
All Other Fees					—				—
Total Fees				$	434,530			$	418,490

(1)	Audit related fees consists of work performed with respect to the audit of the financial statements of the Company's benefit plans.

(2)	Tax fees relate to tax compliance and consultations.

All of the services set forth in the categories above were approved in advance by the Audit Committee.

18

---

The Audit Committee considered whether the provision of such non-audit services by KPMG LLP to the Company is compatible with maintaining KPMG LLP's independence, and concluded that such services were compatible.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-audit Services of Independent Auditors

Consistent with SEC policies regarding auditor independence, the Audit Committee has responsibility for appointing, setting compensation and overseeing the work of the independent auditor. In recognition of this responsibility, the Audit Committee has established a policy to pre-approve all audit and permissible non-audit services provided by the independent auditor.

Prior to engagement of the independent auditor for the next year's audit, management will submit an aggregate of services expected to be rendered during that year for each of four categories of services to the Audit Committee for approval:

1.	Audit services include audit work performed in the preparation of financial statements, as well as work that generally only the independent auditor can reasonably be expected to provide, including comfort letters, statutory audits and attest services and consultation regarding financial accounting and/or reporting standards.

2.	Audit-Related services are for assurance and related services that are traditionally performed by the independent auditor, including due diligence related to mergers and acquisitions, employee benefit plan audits and special procedures required to meet certain regulatory requirements.

3.	Tax services include all services performed by the independent auditor's tax personnel except those services specifically related to the audit of the financial statements, and includes fees in the areas of tax compliance, tax planning, and tax advice.

4.	Other Fees are those associated with services not captured in the other categories.

Prior to engagement, the Audit Committee pre-approves these services by category of service. The fees are budgeted and the Audit Committee requires the independent auditor and management to report actual fees compared to the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage the independent auditor for additional services not contemplated in the original pre-approved services. In those instances, the Audit Committee requires specific pre-approval before engaging the independent auditor.

The Audit Committee may delegate pre-approval authority to one or more of its members. The member or members to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting.

The Board of Directors of the Company recommends a vote FOR the ratification of KPMG LLP as the independent public accountants to audit the Company's consolidated financial statements for the fiscal year ending June 30, 2005, which is designated as Proposal 2 on the enclosed proxy card.
