      A “quorum” is the presence at the meeting, in person or by proxy, of the holders of a majority of the outstanding shares of AptarGroup’s common stock on March 10, 2005. There must be a quorum for the meeting to be held. Proxies received but marked as abstentions and broker non-votes will be included in the calculation of the number of shares considered to be present at the meeting.

      If you hold shares of AptarGroup through your 401(k) plan, you will be instructing the trustee how to vote your shares by completing and returning your proxy card, voting by phone or by the internet. If you do not return your proxy card, or if you return it with unclear voting instructions, or if you do not vote by phone or the internet, the trustee will vote the shares in your 401(k) account in the same proportion as the 401(k) shares for which voting instructions are received.

      If you own shares through a broker, you should be contacted by your broker regarding a proxy card and whether telephone or internet voting options are available. If you do not instruct your broker on how to vote your shares, your broker, as the registered holder of your shares, may represent your shares at the annual meeting for purposes of determining a quorum. Any unvoted shares, called “broker non-votes,” will not affect the outcome of the matter put to a vote.

      The three persons receiving the greatest number of votes will be elected to serve as directors. As a result, withholding authority to vote for a director nominee and non-votes with respect to the election of directors will not affect the outcome of the election.

      Our agent, ADP Investor Communication Services, will count the votes cast by proxy or in person at the annual meeting.

The Board of Directors proposes the following nominees, each of whom is currently serving as a director, to be elected for a new term expiring at the 2008 annual meeting.

      If any of the director nominees is unable or fails to stand for election, the persons named in the proxy presently intend to vote for a substitute nominee nominated by the Corporate Governance Committee of the Board of Directors. The following sets forth information as to each nominee for election at this meeting and each director continuing in office.

Table of Contents

        The Board of Directors has four committees: the Corporate Governance, Audit, Compensation and Executive Committees. Each committee is governed by a charter approved by the Board of Directors. The Board has made these charters available through the Corporate Governance link on the Investor Relations page of the AptarGroup website at the following address: http://www.aptargroup.com. Each member of the Corporate Governance, Audit and Compensation Committees meets the independence requirements of the New York Stock Exchange. Committees report their actions to the full Board at its next regular meeting. An affirmative vote of at least 70% of the Board is required to change the size, membership or powers of these committees, to fill vacancies in them, or to dissolve them. A description of the duties of each committee follows the table below.

      The Board met 7 times in 2004. No current director attended fewer than 75% of the aggregate number of meetings of the Board of Directors and the committees on which each director served. AptarGroup does not have a formal policy regarding director attendance at the annual meeting of stockholders. Messrs. Siebel and Hagge attended the 2004 annual meeting.

        Employees of AptarGroup do not receive any additional compensation for serving as members of the Board or any of its committees. Compensation of non-employee directors consists of the following:

      Each director is reimbursed for out-of-pocket expenses incurred in attending Board and committee meetings.

      Pursuant to the 2000 Director Stock Option Plan, on May 14, 2001, each non-employee director, except for Rodney L. Goldstein who was not yet a member of the Board at that time, was granted a non-qualified option to purchase 8,000 shares of common stock at a price of $34.40 per share. On May 12, 2003, Mr. Goldstein was granted a non-qualified option to purchase 4,000 shares of common stock at a price of $35.02 per share. Each option granted to the directors became exercisable as to 2,000 shares six months after the date of grant and an additional 2,000 shares became exercisable on the earlier of each anniversary of the date of grant or the day before each annual meeting of stockholders. Under the 2000 Director Stock Option Plan, each non-employee director is only eligible for one grant under the Plan.

      Pursuant to the 2004 Director Stock Option Plan, on the third trading date following the date of the 2005 annual meeting, each non-employee director (currently seven persons) will receive a non-qualified option to purchase 8,000 shares of common stock at a purchase price equal to the fair market value of the common stock on the date of grant. Each option will become exercisable as to 2,000 shares on the date which is six months after the date of grant and an additional 2,000 shares will become exercisable on the earlier of each anniversary of the date of grant or the day before each annual meeting of stockholders. Under the 2004 Director Stock Option Plan, a non-employee director is only eligible for one grant under the Plan.

        AptarGroup’s corporate governance documents, including our Corporate Governance Principles, Code of Business Conduct and Ethics, and Board Committee Charters, are available through the Corporate Governance link on the Investor Relations page of the AptarGroup web site at the following

Table of Contents

Corporate Governance Principles

      The Board of Directors has adopted a set of Corporate Governance Principles to provide guidelines for AptarGroup and the Board of Directors to ensure effective corporate governance. The Corporate Governance Principles cover topics including, but not limited to, director qualification standards, Board and committee composition, director responsibilities, director compensation, director access to management and independent advisors, director orientation and continuing education, succession planning and the annual evaluations of the Board and its committees. The Corporate Governance Committee is responsible for overseeing and reviewing the Corporate Governance Principles and recommending to the Board any changes to the principles.

Code of Business Conduct and Ethics

      Ethical business conduct is a shared value of our Board of Directors, management and employees. AptarGroup’s Code of Business Conduct and Ethics applies to our Board of Directors as well as our employees and officers, including our principal executive officer and our principal financial and accounting officer.

      The Code of Business Conduct and Ethics covers all areas of professional conduct, including, but not limited to, conflicts of interest, disclosure obligations, insider trading, confidential information, as well as compliance with all laws, rules and regulations applicable to AptarGroup’s business. AptarGroup encourages all employees, officers and directors to promptly report any violations of the Code to the appropriate persons identified in the Code. In the event that an amendment to, or a waiver from, a provision of the Code of Business Conduct and Ethics that applies to any of our directors or executive officers is necessary, AptarGroup intends to post such information on its web site.

Independence of Directors

      Our Corporate Governance Guidelines provide that the Board must be composed of a majority of independent directors. No director qualifies as independent unless the Board affirmatively determines that the director has no material relationship with AptarGroup either directly or as a partner, stockholder or officer of an organization that has a relationship with AptarGroup. Our Board of Directors has determined that all non-management directors (seven out of ten directors) are independent in accordance with the New York Stock Exchange listing standards. The Board has made this determination based on the following categorical standards, in addition to any other relevant facts and circumstances. These standards provide that a director generally will not be independent if:

Table of Contents

Executive Sessions

      Non-management directors meet regularly in executive sessions without management. “Non-management” directors are all those who are not company officers. Executive sessions are led by a “Presiding Director.” An executive session is held in conjunction with each regularly scheduled Board meeting and other sessions may be called by the Presiding Director in his or her own discretion or at the request of the Board. Mr. Harris has been designated as the Presiding Director.

10

Table of Contents

Nomination of Directors

      It is the policy of the Corporate Governance Committee to consider candidates for director recommended by stockholders. In order to recommend a candidate, stockholders must submit the individual’s name and qualifications in writing to the Committee (in care of the Secretary at AptarGroup’s principal executive office at 475 West Terra Cotta Avenue, Suite E, Crystal Lake, Illinois 60014) and otherwise in accordance with all of the procedures outlined under “Other Matters — Stockholder Proposals” for a director nomination.

      In identifying and evaluating nominees for Director, the Committee takes into account the applicable requirements for directors under the Securities Exchange Act of 1934, as amended, and the listing standards of the New York Stock Exchange. In addition, the Committee may take into consideration such factors and criteria as it deems appropriate, including the nominee’s character, judgment, business experience and acumen. In addition to nominees recommended by stockholders, the Committee also considers candidates recommended by management or other members of the Board. The Committee evaluates candidates recommended for Director by stockholders in the same way that it evaluates any other nominee.

Communications with the Board of Directors

      The Board has established a process for stockholders and other interested parties to communicate with the Board or an individual director, including the Presiding Director or the non-management directors as a group. A stockholder may contact the Board of Directors or an individual director by writing to their attention at AptarGroup’s principal executive offices at 475 West Terra Cotta Avenue, Suite E, Crystal Lake, Illinois 60014. Communications received in writing are distributed to the Board or to individual directors as appropriate in accordance with procedures approved by AptarGroup’s independent directors.

      The compensation policy is designed to support AptarGroup’s overall objective of increasing stockholder value by:

       4Attracting, motivating and retaining key executives who are critical to the long-term success of AptarGroup.

       4Awarding short-term incentives based upon respective unit performance and overall AptarGroup performance.

       4Aligning executive and stockholder interests through a stock-based long-term incentive program which will reward executives for increased stockholder value.

      Section 162(m) of the U.S. Internal Revenue Code generally disallows a tax deduction for compensation in excess of $1 million paid to AptarGroup’s Chief Executive Officer and the four other most highly compensated executive officers. Certain compensation is specifically exempt from the deduction limit to the extent that it does not exceed $1 million during any fiscal year, or is “performance based”, as defined in Section 162(m). The Compensation Committee’s general policy is to qualify U.S. incentive compensation of executives for deductibility under Section 162(m).

      The total compensation program consists of three components:

      Management performance and accomplishment of goals and objectives are important factors in determining base salary increases. In addition, the salary ranges of executive officers are established in relation to competitive market data provided by outside executive compensation consultants and review of proxy statements of similar publicly-held companies in the packaging industry. Comparisons are made to positions with similar job responsibilities in companies with comparable revenue to that of AptarGroup. Four of the companies used in establishing salary ranges are included in the Value Line Packaging & Container Industry Group used in the performance graph below. Generally, salaries are established between the 50th and 75th percentiles of market rates. Salaries are reviewed annually and compared to market rates every two years.

      Executives are eligible for annual bonuses based upon:

       4Profit growth

       4Return on capital

14

Table of Contents

       4Achievement of other goals and objectives

       4General management performance

      Profit growth and return on capital are weighted most important in determining annual bonuses. The bonuses of Messrs. Siebel, Pfeiffer and Hagge are discretionary as determined by the Committee after reviewing AptarGroup’s overall performance, strategic actions implemented and individual leadership achievements. Based upon an evaluation of these criteria, including, in particular, the strong financial performance of AptarGroup during 2004 in which AptarGroup reported record net sales and earnings per share and achieved its 39th consecutive year of sales growth, the total 2004 bonuses for Messrs. Siebel, Pfeiffer and Hagge were increased over the prior year. When compared to the prior year, the bonuses for Messrs. Siebel, Pfeiffer and Hagge increased approximately 15%, 14% and 30%, respectively. For 2004, the bonuses of Messrs. Doherty and Blanié were determined by a formula that takes into consideration, among other criteria, profit growth and return on capital of their respective operating group and AptarGroup’s earnings per share growth.

      Executives are eligible for awards of stock options and restricted stock under AptarGroup’s Stock Awards Plans. The awards to executives are made to provide an incentive for future performance to increase stockholder value and the awards generally vest ratably over a three year period. The members of the Compensation Committee administer this Plan. In 2004, the total amount of options granted was approximately 1.6% of the total stock outstanding. As reflected in the table of option grants, stock options were granted on June 3, 2004 to all of the named executive officers. Awards were determined in relation to the individual’s position and responsibility. The exercise price of the options equaled the market price of AptarGroup’s common stock on the date of the grants.

      To further encourage executive officer share ownership, executive officers may defer up to 50% of their annual cash bonus and receive, in lieu of cash, a grant of restricted stock units equal to the deferred amount plus an additional 20%. The value of each restricted stock unit is determined by the closing share price on the New York Stock Exchange on the day of grant. All of the restricted stock units vest ratably over three years from the date of grant and dividends are paid on vested units only.

      Mr. Siebel’s salary was increased by approximately 6% to $700,000 in January 2004, as compensation for his performance. The Committee typically sets the CEO’s compensation slightly above the 50th percentile of the salary range for comparable companies. His 2004 bonus of $575,000 was established based upon AptarGroup’s overall performance, strategic actions implemented and leadership achievements. During 2004, Mr. Siebel was awarded an option to purchase 90,000 shares of common stock.

Table of Contents

      The following table provides information as to options exercised and the value of options held by the named executive officers at year-end measured in terms of the closing price of the common stock on December 31, 2004. AptarGroup has not granted any SARs.

      Mr. Siebel’s employment agreement provides for employment through December 31, 2005 at a minimum salary of $700,000 per year, which amount may be increased (but not decreased) over the remaining term of the agreement and provides for a payment of three months’ salary to his survivors in the event of his death while employed. The agreement provides for an automatic extension for a period of one year, unless it is terminated by AptarGroup or Mr. Siebel by written notice seven months before the end of the then current contract period. A separate pension agreement provides Mr. Siebel with annual pension compensation, subject to cost of living adjustments, of 60% of his Euro denominated 2000 salary for life, and in the event of his death, provides his surviving widow with annual payments of 60% of his then pension for life. Mr. Siebel began receiving payments from this pension in February 2000, and pension payments for the year 2004, which are denominated in Euros, were equivalent to approximately $472,000. Benefits are not subject to reduction for Social Security benefits or other offset items.

      Mr. Pfeiffer’s employment agreement provides for employment through April 21, 2008 at a minimum salary of $465,000 per year, which amount may be increased (but not decreased) over the remaining term of the agreement and provides for a payment of three months’ salary to his survivors in the event of his death while employed. The agreement provides for an automatic extension for a period of five years, unless it is terminated by AptarGroup or Mr. Pfeiffer by written notice one year before the end of the then current contract period; however, the agreement automatically terminates on June 28,

18

Table of Contents

      Mr. Hagge’s employment agreement expires December 1, 2007. The agreement is automatically extended for one additional year each December 1. AptarGroup or Mr. Hagge may terminate the automatic extension provision by written notice to the other party at least 30 days prior to the automatic extension date. The agreement provides that Mr. Hagge will receive a minimum salary of $355,000 per year, which amount may be increased (but not decreased) over the remaining term of the agreement. In addition to participation in executive benefit programs on the same basis as other executives, Mr. Hagge is entitled to additional term life and supplementary long-term disability insurance coverage. If employment ends on account of death, Mr. Hagge’s estate will receive one-half of the annual salary that Mr. Hagge would have received until the second anniversary of his death. If employment ends due to the expiration of the agreement, Mr. Hagge is entitled to receive an amount equal to one year’s salary (based on the salary then in effect) and medical and life insurance benefits he would have otherwise received for a period of one year following the expiration date. If Mr. Hagge terminates the agreement without “good reason” (as defined in the agreement) or he retires, he is not entitled to payments or benefits under the employment agreement (other than certain accrued amounts and plan benefits which by their terms extend beyond termination of employment). If Mr. Hagge is terminated without “cause” (as defined in the agreement), he is entitled to receive his base salary then in effect (at the times it would have been paid) until the date on which the agreement was scheduled to expire.

      After a change in control of AptarGroup, if Mr. Hagge’s employment is terminated without “cause” or if he terminates his employment for “good reason”, in each case within two years following the change in control, Mr. Hagge is entitled to receive (i) a lump-sum payment equal to two times his annual salary and bonus amounts, based on the highest annualized amounts received in the 12 month period preceding the termination, (ii) a prorated annual bonus and (iii) all medical, disability and life insurance coverage then in effect for a period of two years following termination. In the event that such payments and benefits subject Mr. Hagge to any excise tax, Mr. Hagge would generally be entitled to receive a “gross-up” payment to reimburse him for such excise tax. The agreement contains certain noncompetition and nonsolicitation covenants prohibiting Mr. Hagge from, among other things, becoming employed by a competitor of AptarGroup for a period of one or two years following termination (depending on the nature of the termination).

      Mr. Doherty’s employment agreement contains terms that are substantially identical to Mr. Hagge’s agreement, except that Mr. Doherty’s agreement provides that Mr. Doherty will receive a minimum salary of $280,000 per year, which amount may be increased (but not decreased) over the remaining term of the agreement.

Table of Contents

      Mr. Blanié has employment agreements with SeaquistPerfect Dispensing SAS (“French Agreement”) and SeaquistPerfect Dispensing GmbH (“German Agreement”), both subsidiaries of AptarGroup. The agreements provide that Mr. Blanié will receive an aggregate minimum annual salary (which is denominated in Euros) of approximately $266,000 and will be entitled to receive an annual bonus. The French Agreement is governed by the French Collective Bargaining Agreement of the Plastics Industry. The French Agreement does not have a specific term, but may be terminated by either party as provided for under French law. The German Agreement, which outlines certain management responsibilities, may be terminated by either party with 12 months written notice and expires when Mr. Blanié reaches the age of 65. The agreements contain certain noncompetition and nonsolicitation covenants prohibiting Mr. Blanié from engaging in competitive activities with AptarGroup in the European Union for a period of two years following any termination of the agreements. In consideration for these covenants, Mr. Blanié is entitled during that two-year period to compensation equivalent to one year of salary based upon his most recent annual salary prior to termination.

      Substantially all of the U.S. employees of AptarGroup and its subsidiaries are eligible to participate in the AptarGroup Pension Plan. Employees are eligible to participate after six months of credited service and become fully vested after five years of credited service. The annual benefit payable to an employee under the Pension Plan upon retirement computed as a straight life annuity equals the sum of the separate amounts the employee accrues for each of his years of credited service under the Plan. Such separate amounts are determined as follows: for each year of credited service through 1988, 1.2% of such year’s compensation up to the Social Security wage base for such year and 1.8% (2% for years after 1986) of such year’s compensation above such wage base, plus certain increases put into effect prior to 1987; for each year after 1988 through the year in which the employee reaches 35 years of service, 1.2% of such year’s “Covered Compensation” and 1.85% of such year’s compensation above such “Covered Compensation;” and for each year thereafter, 1.2% of such year’s compensation. The employee’s compensation under the Pension Plan for any year includes all salary, commissions and overtime pay and, beginning in 1989, bonuses, subject to such year’s limit applicable to tax-qualified retirement plans. The employee’s “Covered Compensation” under the Pension Plan for any year is generally the average of the Social Security wage base for each of the 35 years preceding the employee’s Social Security retirement age, assuming that such year’s Social Security wage base will not change in the future. Normal retirement under the Pension Plan is age 65 and reduced benefits are available as early as age 55. Benefits are not subject to reduction for Social Security benefits or other offset items.

      U.S. employees of AptarGroup and its subsidiaries participating in the Pension Plan are also eligible for AptarGroup’s non-qualified supplemental retirement plan (“SERP”). The benefits payable under the SERP will generally be in the form of a single sum and will be computed as a single life annuity equal to the sum of the separate amounts the participant accrues for each year of credited service. Such separate amounts are determined as follows: for each year of credited service through the year in which the participant reaches 35 years of service, 1.85% of the participant’s “Supplemental Earnings;” and for each year after 35 years of credited service, 1.2% of such year’s “Supplemental Earnings.” “Supplemental Earnings” is generally the difference between (i) the participant’s earnings calculated as if the limitation of Section 401(a)(17) of the Internal Revenue Code were not in effect and (ii) the

20

Table of Contents

      Estimated annual benefits payable under the Pension Plan and the SERP upon retirement at normal retirement age for Messrs. Hagge and Doherty are approximately $242,000 and $186,000, respectively.

      Messrs. Siebel, Pfeiffer and Blanié are not eligible to receive benefits under the Pension Plan but, as described above under “Employment Agreements”, Messrs. Siebel and Pfeiffer are entitled to certain pension benefits pursuant to their respective employment agreements. Mr. Blanié is eligible for benefits pursuant to a supplemental pension plan available to certain European executives. This plan provides participants with an annual pension compensation for life, subject to cost of living adjustments, of up to 10% of the average annual salary and bonus paid to a participant in the five years preceding retirement. In the event of a participant’s death after retirement, the plan provides a surviving spouse with annual payments of 60% of the participant’s pension for life. Pension benefits would normally commence at age 65, but reduced benefits are available after age 55. Estimated annual pension benefits for Mr. Blanié upon retirement at age 65 (assuming reasonable increases in compensation) are equivalent to approximately $48,000. Benefits under this plan will be reduced to the extent that aggregate pension benefits from all sources exceed 55% of the average salary and bonus paid to the participant in the five years preceding retirement.

        In 1999, AptarGroup acquired companies that were owned by Mr. Emil Meshberg and certain members of his family. Mr. Meshberg became an executive officer of AptarGroup immediately following the acquisitions and he continues to serve in such capacity. AptarGroup currently leases real estate from, makes license royalty payments to and sells products to entities related to Mr. Meshberg or certain members of his family. The transactions between AptarGroup and these entities were at arms-length and, in 2004, amounted to lease payments of approximately $184,000, license royalty payments of approximately $65,000 and sales of approximately $212,000.

        Based solely upon a review of reports and written representations furnished to it, AptarGroup believes that during 2004 all filings with the Securities and Exchange Commission by its executive officers and directors complied with requirements for reporting ownership and changes in ownership of AptarGroup’s common stock pursuant to Section 16(a) of the Securities Exchange Act of 1934, except that Mr. Olivier Fourment filed one report on May 24, 2004, which included one transaction that had not been reported on a timely basis, and Mr. Francois Boutan filed one report on June 2, 2004, which included one transaction that had not been reported on a timely basis.

        The Board of Directors has determined that each member of the Audit Committee is financially literate and independent in accordance with the requirements of the New York Stock Exchange. The Board of Directors has also determined that Rodney L. Goldstein and Dr. Leo A. Guthart qualify as “audit committee financial experts” as that term is defined in rules of the Securities and Exchange Commission implementing requirements of the Sarbanes-Oxley Act of 2002. In reaching this determination, the Board of Directors considered, among other things, the relevant experience of Mr. Goldstein and Dr. Guthart as described under “Election of Directors.” The Audit Committee operates under a written charter adopted by the Board, a copy of which is attached as Appendix A to this Proxy Statement. The charter complies with all current regulatory requirements.

      Management is responsible for AptarGroup’s internal controls and the financial reporting process. The independent accountants are responsible for performing an independent audit of AptarGroup’s consolidated financial statements in accordance with generally accepted auditing standards and issuing a report thereon. The Committee’s responsibility is to assist the Board in fulfilling its responsibility for overseeing the quality and integrity of the accounting, auditing and financial reporting practices of AptarGroup.

      During the course of the fiscal year ended December 31, 2004, management completed the documentation, testing and evaluation of the Company’s system of internal control over financial reporting in response to the requirements set forth in Section 404 of the Sarbanes-Oxley Act of 2002 and related regulations. Management and the independent accountants kept the Committee apprised of the

      The Committee has reviewed and discussed the consolidated financial statements with management and the independent accountants. Management has represented to the Committee that the consolidated financial statements were prepared in accordance with generally accepted accounting principles. Also, the Committee has discussed with the independent accountants the matters required to be discussed by Statement on Auditing Standards No. 61 (Communication with Audit Committees), as amended.

      In addition, the Committee discussed with the independent accountants the accountants’ independence from AptarGroup and its management, and the independent accountants provided the Committee the written disclosures and letter required by the Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees). In considering the independence of AptarGroup’s independent accountants, the Committee took into consideration the amount and nature of the fees paid to the independent accountants for non-audit services as described under “Other Matters — Independent Auditor Fees” in this Proxy Statement.

      Based on the review and discussions referred to above, the Committee recommended to the Board of Directors, and the Board has approved, that the audited consolidated financial statements be included in AptarGroup’s Annual Report on Form 10-K for the year ended December 31, 2004, for filing with the Securities and Exchange Commission.

      PricewaterhouseCoopers LLP served as independent auditors for the year ended December 31, 2004. The Audit Committee’s decision regarding the selection of the independent auditors to audit AptarGroup’s consolidated financial statements for the year ending December 31, 2005 has not yet been made. It is expected that a representative of PricewaterhouseCoopers LLP will attend the annual meeting, with the opportunity to make a statement if he or she should so desire, and will be available to respond to appropriate questions.

      The following table sets forth the aggregate fees charged to AptarGroup by PricewaterhouseCoopers LLP for audit services rendered in connection with the audited consolidated financial statements and reports for the 2004 and 2003 fiscal years and for other services rendered during the 2004 and 2003 fiscal years to AptarGroup and its subsidiaries, as well as all out-of-pocket costs incurred in connection with these services:

      Audit Fees primarily represent amounts billed for the audit of AptarGroup’s annual financial statements, reviews of SEC Forms 10-Q and 10-K, statutory audit requirements at certain non-U.S. locations, and for the first time in 2004, approximately $1,700,000 for work related to the attestation of management’s report on the effectiveness of internal controls over financial reporting according to the requirements of Section 404 of the Sarbanes-Oxley Act of 2002.

      Audit-Related Fees include approximately $420,000 for services related to AptarGroup’s preparation to meet the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, and other amounts related to the audits of benefit plans and consultations concerning financial accounting and reporting standards and new regulations.

      Tax Fees primarily represent amounts billed for tax compliance and preparation services including federal, state and international tax compliance, assistance with tax audits and appeals, and tax work related to foreign entity statutory audits.

      Other Fees in 2003 consisted of amounts billed for permissible non-audit services other than those included above.

Table of Contents

      The Audit Committee’s policies and procedures require pre-approval for all audit and permissible non-audit service to be performed by AptarGroup’s independent auditors. These services are generally pre-approved by the entire Audit Committee.

      AptarGroup will pay the cost of soliciting proxies for the annual meeting. Although AptarGroup has not engaged a proxy solicitor in connection with the 2005 annual meeting, AptarGroup may elect to do so and, in such case, would pay a customary fee for these services. AptarGroup also reimburses banks, brokerage firms and other institutions, nominees, custodians and fiduciaries for their reasonable expenses for sending proxy materials to beneficial owners and obtaining their voting instructions. Certain directors, officers and employees of AptarGroup and its subsidiaries may solicit proxies personally or by telephone, facsimile or electronic means without additional compensation.

      AptarGroup’s Annual Report/ Form 10-K for the year ended December 31, 2004 is being distributed with this proxy statement. Stockholders can refer to the report for financial and other information about AptarGroup, but such report is not incorporated in this proxy statement and is not deemed a part of the proxy soliciting material.
