Item 8. Exhibits

The Exhibits accompanying this Registration Statement are listed on the accompanying Exhibit Index.

Item 9. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high and of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and

-4-

(iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

Notwithstanding the foregoing, in the event that at the time of the existence of an unfilled newly created directorship or vacancy there are unfilled newly created directorships and/or vacancies constituting more than thirty percent (30%) of the whole Board of Directors, a majority of the directors then serving on the Board of Directors shall have the authority to fill enough of such unfilled newly created directorships and/or vacancies so that, after giving effect thereto, there will be the minimum number of directors serving on the Board of Directors necessary to constitute seventy percent (70%) of the whole Board of Directors.

ARTICLE NINE

To the fullest extent permitted by the General Corporation Law of the State of Delaware as the same exists or may hereafter be amended, a director of the Corporation shall not be liable to the Corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director.

(i) any merger or consolidation of the Corporation or any direct or indirect majority-owned subsidiary of the Corporation with
(1) the interested stockholder or (2) any other person if the merger or consolidation is caused by the interested stockholder and as a result of such merger or consolidation Section 11.1 of this Article Eleven is not applicable to the surviving person;

(iii) any transaction which results in the issuance or transfer by the Corporation or by any direct or indirect majority-owned subsidiary of the Corporation of any stock of the Corporation or of such subsidiary to the interested stockholder, except (1) pursuant to the exercise, exchange or conversion of securities exercisable for, exchangeable for or convertible into stock of the Corporation or any such subsidiary which securities were outstanding prior to the time that the interested stockholder became such, (2) pursuant to a dividend or distribution paid or made, or the exercise, exchange or conversion of any security exercisable for, exchangeable for or convertible into stock of the Corporation or any such subsidiary which security is distributed, pro rata to all holders of a class or series of stock of the Corporation subsequent to the time the interested stockholder became such, (3) pursuant to an exchange offer by the Corporation to purchase stock made on the same terms to all holders of said stock, or (4) any issuance or transfer of stock by the Corporation, provided however, that in no case under (2) - (4) above shall there be an increase in the interested stockholder's proportionate share of the stock of any class or series of the Corporation or of the voting stock of the Corporation;

-9-

(iv) any transaction involving the Corporation or any direct or indirect majority-owned subsidiary of the Corporation which has the effect, directly or indirectly, of increasing the proportionate share of the stock of any class or series, or of securities exercisable for, exchangeable for or convertible into the stock of any class or series, of the Corporation or of any such subsidiary which is owned by the interested stockholder, except as a result of immaterial changes due to fractional share adjustments or as a result of any purchase or redemption of any shares of stock not caused, directly or indirectly, by the interested stockholder; or

Notwithstanding the foregoing sentence, none of the persons described in clause (i) above shall continue to be an exempt person by virtue of such clause after the earliest date after the Pfeiffer Share Exchange on which such persons are owners in the aggregate of less than 3% of the Corporation's outstanding voting stock (determined without taking into account any securities exercisable or exchangeable for, or convertible into, the Corporation's voting stock, other than any such securities owned by such persons), and none of the persons described in clause (ii) above shall continue to be an exempt person by virtue of such clause after the earliest date after the Pfeiffer Share Exchange on which such persons are owners in the aggregate of less than 3% of the Corporation's outstanding voting stock (determined without taking into account any securities exercisable or exchangeable for, or convertible into, the Corporation's voting stock, other than any such securities owned by such persons).

For the purpose of determining whether a person is an interested stockholder, the voting stock of the Corporation deemed to be outstanding shall include stock deemed to be owned by the person through application of subsection (H) of this Section 11.3 but shall not include any other unissued stock of the Corporation which may be issuable pursuant to any agreement, arrangement or understanding, or upon exercise of conversion rights, warrants or options, or otherwise.

(i) beneficially owns (as determined pursuant to Rule 13d-3 of the General Rules and Regulations under the Securities Exchange Act of 1934 or any successor provision) such stock, directly or indirectly; or

(ii) has (1) the right to acquire such stock (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding, or upon the exercise of exercise rights, conversion rights, exchange rights, warrants or options, or otherwise; provided, however, that a person shall not be deemed the owner of stock tendered pursuant to a tender or exchange offer made by such person or any of such person's affiliates or associates until such tendered stock is accepted for purchase or exchange; or (2) the right to vote such stock pursuant to any agreement, arrangement or understanding; provided, however, that a person shall not be deemed the owner of any stock because of such person's right to vote such stock if the agreement, arrangement or understanding to vote such stock arises solely from a revocable proxy or consent given in response to a proxy or consent solicitation made to 10 or more persons; or

-11-

(iii) has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting (except voting pursuant to a revocable proxy or consent as described in item (2) of clause (ii) of this subsection), or disposing of such stock with any other person that beneficially owns, or whose affiliates or associates beneficially own, directly or indirectly, such stock.

ARTICLE TWELVE

In the event that it is proposed that the Corporation enter into a merger or consolidation with any other corporation (other than a direct or indirect wholly-owned subsidiary of the Corporation), or sell or otherwise dispose of all or substantially all of its assets or business in one transaction or a series of transactions, or liquidate or dissolve, the affirmative vote of the holders of not less than eighty percent (80%) of the outstanding shares of Common Stock entitled to vote on each matter on which the holders of record of Common Stock shall be entitled to vote shall be required for the approval of such proposal; provided, however, that the foregoing shall not apply to any such merger, consolidation, sale, disposition, liquidation or dissolution which is approved by resolution of two-thirds of the whole Board of Directors, if the majority of the members of the Board of Directors adopting such resolution were members of the Board of Directors of the Corporation prior to the public announcement of the proposed merger, consolidation, sale, disposition, dissolution or liquidation and prior to the public announcement of any transaction relating to such merger, consolidation, sale, disposition, dissolution or liquidation. If such approval is granted, then such transaction shall only require the approval otherwise required under the other Articles of this Certificate of Incorporation and under law. For purposes of this Article Twelve, "whole Board of Directors" means the total number of directors which the Corporation would have on the Board of Directors if there were no vacancies. The provisions set forth in this Article Twelve may not be amended, altered, changed or repealed in any respect unless such action is approved by the affirmative vote of the holders of not less than eighty percent (80%) of the outstanding shares of Common Stock entitled to vote on each matter on which the holders of record of Common Stock shall be entitled to vote.

ARTICLE THIRTEEN

13.1 Indemnification of Officers, Directors and Others. The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including any action by or in the right of the Corporation) (a "Proceeding") by reason of the fact that he is or was a director, officer or employee of the Corporation, or is or was serving at the request of the Corporation as a director, officer or employee of another corporation, partnership, joint venture, trust or other enterprise (including service with respect to any employee benefit plan) against expenses (including attorneys' fees), judgments, fines, ERISA excise taxes, penalties and amounts paid in settlement actually and reasonably incurred by him in connection with such Proceeding to the fullest extent permitted by the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide prior to such amendment). The indemnification provided by this Article Thirteen shall not be deemed exclusive of any other rights to which any person may be entitled under any By-Law, agreement, vote of stockholders or disinterested directors, or otherwise, both as to action in his official capacity and as to action in another capacity, and shall continue as to a person who has ceased to be a director, officer or employee and shall inure to the benefit of the heirs, executors, administrators and personal representatives of such a person. It is expressly understood that, notwithstanding the foregoing, no director, officer or employee shall have any rights under this Article Thirteen if the Proceeding giving rise to the claim for indemnification hereunder arises as a result of actions or failures to act in any capacity other than those set forth in this Section 13.1, and, as such, no such person shall have any rights under this Article Thirteen if the Proceeding giving rise to the claim for indemnification arises as a result of such person's purchase and/or sale of securities of the Corporation (other than on behalf of the Corporation).

-13-

13.2 Procedure for Indemnification of Directors, Officers and Employees. Any indemnification of a director, officer or employee of the Corporation or advance of expenses under this Article Thirteen shall be made promptly upon the written request of the director, officer or employee, and in any event within 30 days after such request (or, if a determination as described below is required, within 30 days after such determination has been made or deemed made). If a determination by the Corporation that the director, officer or employee is entitled to indemnification pursuant to this Article Thirteen is required, and the Corporation fails to respond within sixty days to a written request for indemnity, the Corporation shall be deemed to have approved the request. If the Corporation denies a written request for indemnification or advancing of expenses, in whole or in part, or if payment in full pursuant to such request is not made within 30 days after such request (or, if a determination as described above is required, within 30 days after such determination has been made or deemed made), the right to indemnification or advances as granted by this Article Thirteen shall be enforceable by the director, officer or employee in any court of competent jurisdiction. Such person's costs and expenses incurred in connection with successfully establishing his right to indemnification, in whole or in part, in any such action shall also be indemnified by the Corporation. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any Proceeding in advance of its final disposition where the required undertaking has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the General Corporation Law of the State of Delaware for the Corporation to indemnify the claimant for the amount claimed, but the burden of such defense shall be on the Corporation. Neither the failure of the Corporation (including its board of directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he has met the applicable standard of conduct set forth in the General Corporation Law of the State of Delaware, nor an actual determination by the Corporation (including its board of directors, independent legal counsel, or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

-14-

13.3 Insurance. The Corporation may purchase and maintain insurance on its own behalf and on behalf of any person who is or was a director, officer or employee of the Corporation or was serving at the request of the Corporation as a director, officer or employee of another corporation, partnership, joint venture, trust or other enterprise (including service with respect to any employee benefit plan) against any liability asserted against him and incurred by him in any such capacity, whether or not the Corporation would have the power to indemnify such person against such liability under this Article Thirteen.

13.4 Expenses. Expenses incurred by any person described in this Article Thirteen in defending a Proceeding shall be paid by the Corporation in advance of such Proceeding's final disposition upon receipt of an undertaking by or on behalf of the director, officer or employee to repay such amount without interest if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation.

13.5 Contract Rights. The provisions of this Article Thirteen shall be deemed to be a contract between the Corporation and each director, officer or employee who serves in any such capacity at any time, and any repeal or modification of this Article Thirteen or of any relevant provisions of the General Corporation Law of the State of Delaware or other applicable law shall not affect any rights or obligations then existing with respect to any state of facts or Proceeding then existing.

13.6 Merger or Consolidation. For purposes of this Article Thirteen, references to "the Corporation" shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers and employees, so that any person who is or was a director, officer or employee of such a constituent corporation, or is or was serving at the request of such a constituent corporation as a director, officer or employee of another corporation, partnership, joint venture, trust or other enterprise (including service with respect to any employee benefit plan), shall stand in the same position under this Article Thirteen with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued.

13.7 Indemnification of Agents. The Corporation may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification and to the advancement of expenses to any agent of the Corporation to the fullest extent of the provisions of this Article Thirteen with respect to the indemnification and advancement of expenses of directors, officers and employees of the Corporation.

13.8 Amendment. The provisions set forth in this Article Thirteen may not be amended, altered, changed or repealed in any respect unless such actions approved by the affirmative vote of the holders of not less than eighty percent (80%) of the outstanding shares of Common Stock entitled to vote on each matter on which the holders of record of Common Stock shall be entitled to vote.

-15-

ARTICLE FOURTEEN

The Corporation is to have perpetual existence.

ARTICLE FIFTEEN

The Corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation in the manner now or hereafter prescribed herein and by the laws of the State of Delaware, and all rights conferred upon stockholders herein are granted subject to this reservation.

Ladies and Gentlemen:

We refer to the Registration Statement on Form S-8 (the "Registration Statement") being filed by AptarGroup, Inc., a Delaware corporation (the "Company"), with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Securities Act"), relating to the registration of 4,300,000 shares of common stock, par value $.01 per share (the "Shares"), of the Company, together with 4,300,000 preferred stock purchase rights (the "Rights") associated therewith, to be issued under the Company's 2008 Stock Option Plan and 2008 Director Stock Option Plan (collectively, the "Plans"). The terms of the Rights are set forth in the Rights Agreement dated as of April 7, 2003 (the "Rights Agreement") between the Company and National City Bank, as Rights Agent.

We are familiar with the Amended and Restated Certificate of Incorporation of the Company, as amended, the Amended and Restated By-laws of the Company and the resolutions of the Board of Directors of the Company relating to the Plans and the Registration Statement.

In this connection, we have examined such records, documents and questions of law, and have satisfied ourselves as to such matters of fact, as we have considered relevant and necessary as a basis for the opinions set forth herein. We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of all natural persons and the conformity with the original documents of any copies thereof submitted to us for our examination.

Based upon the foregoing, we are of the opinion that:
