Not Applicable.

The legal opinion regarding the validity of the securities to be issued is rendered by Ryan Metz, Associate General Counsel, Elastomers & Primary Containment, of the Company.

------

**Item 6. Indemnification of Directors and Officers.** 

The Company maintains a policy of insurance under which the respective directors and officers (as defined therein) of the Company are insured subject to specified exclusions and deductibles and retention and maximum amounts against loss arising from any civil claim or claims which may be made against any director or officer (as so defined) of the Company by reason of any breach of duty, neglect, error, misstatement, misleading statement, omission or act done or wrongfully attempted or alleged to have been done while acting in their respective capacities.

Section 12 of Article II of the Amended and Restated Bylaws of the Company ("the Bylaws") provides that a director shall not be personally liable for monetary damages for any action taken on or after January 27, 1987, or for failure to take any action on or after such date unless (i) the director has breached or failed to perform the duties of his office under Section 512 of the Pennsylvania Business Corporations Law (15 Pa.C.S.A § 512), relating to standard of care and justifiable reliance, and (ii) the breach or failure to perform constitutes self-dealing, willful misconduct or recklessness. The provisions of Section 12 of Article II shall not apply to (i) any criminal statute, or (ii) the liability of a director for the payment of taxes due to local, state or federal law.

Article IV of the Bylaws provides that the Company shall indemnify any person who was or is a party or threatened to be made a party to any threatened, pending or completed action, suit or proceeding by reason of the fact that such person is or was a director, officer, employee or agent of the Company or serving at the request of the Company as a director, officer, employee or agent of another entity. Such indemnification shall be against all expenses, judgments, fines and amounts paid in settlement of such proceedings to the extent that such person has not otherwise been indemnified and the power to give such indemnification has been granted by statute. For this purpose, the Board has the power to buy and maintain insurance at the Company's expense. Payment of expenses may be made to an indemnified person prior to the final disposition of an action.

The Pennsylvania Business Corporations Law authorizes the indemnification set forth above if the actions of the person to be indemnified did not constitute willful misconduct or recklessness or, in the opinion of the Company, self-dealing. The character of the conduct of the person to be indemnified shall be determined by members of the Board not parties to such litigation, independent counsel or the shareholders of the Company. The obligation of the Company to indemnify a director, officer, employee or agent under Article IV constitutes a contract between the Registrant and such person, and no modification or repeal of any provision of Article IV will affect, to the detriment of the director, officer, employee or agent such obligations of the Company in connection with a claim based in any act or failure to act occurring before such modification or repeal.

**Item 7. Exemption from Registration Claimed.** 

Not Applicable.

**Item 9. Undertakings**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.The undersigned Registrant hereby undertakes:

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. To reflect in the prospectus any facts or events arising after the effective date of the 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 the 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 end 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 20% change in the maximum aggregate offering price set forth in the "Calculation of Filing Fee Tables" or "Calculation of Registration Fee" table, as applicable, in the effective Registration Statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the 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 reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;That, for the purpose of determining any liability under the Securities Act, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the Securities Act 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 Commission such indemnification is against public policy as expressed in the Securities Act 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 and will be governed by the final adjudication of such issue.

------

Based on and subject to the foregoing as well as the additional qualifications set forth below, I am of the opinion that the Additional Shares, when issued pursuant to and in accordance with the Plan, will be validly issued, fully paid and non-assessable.

This opinion is being furnished to you solely for submission to the Commission as an exhibit to the Registration Statement and, accordingly, may not be relied upon, quoted in any manner to, or delivered to any other person or entity, without in each instance my prior written consent. This opinion is rendered as of the date hereof, and I assume no obligation to modify, update or supplement this opinion to reflect any changes of applicable law or fact which may hereafter occur.

I hereby consent to the filing of this opinion as an exhibit to the Registration Statement and the reference to me under the heading "Interests of Named Experts and Counsel" in the Registration Statement. By providing such consent, I do not admit that I come within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations promulgated thereunder.
