ARTICLE VII

The private property of the stockholders of the Corporation shall not be subject to the payment of corporate debts to any extent whatever.

ARTICLE VIII

(1) Power of the Board of Directors. The business and affairs of the Corporation shall be managed under the direction of its Board of Directors. In furtherance, and not in limitation, of the powers conferred by the laws of the State of Delaware, the Board of Directors is expressly authorized:

(a) to make, alter, amend or repeal the By-Laws of the Corporation; provided, however, that no By-Laws hereafter adopted shall invalidate any prior act of the Board Directors that would have been valid if such By-Laws had not been adopted;

(b) to determine the rights, powers, duties, rules and procedures that affect the power of the Board of Directors to direct the business and affairs of the Corporation, including the power to designate and empower committees of the Board of Directors, to elect, appoint and empower the officers and other agents of the Corporation, and to determine the time and place of, and the notice requirements for, meetings of the Board

of Directors, as well as quorum and voting requirements (except as otherwise provided in this Certificate of Incorporation) for, and the manner of taking, action of the Board of Directors; and

(c) to exercise all such powers and do all such acts as may be exercised by the Corporation, subject to the provisions of the laws of the State of Delaware, this Certificate of Incorporation, and any By-Laws of the Corporation.

(2) Number of Directors. The number of Directors constituting the entire Board of Directors shall be not less than 5 nor more than 13. Subject to the rights of holders of capital stock of the Corporation (other than the Common Stock) then outstanding, the specific number of Directors constituting the entire Board of Directors shall be as authorized from time to time exclusively by the affirmative vote of a majority of the entire Board of Directors. As used in this Certificate of Incorporation, the term “entire Board of Directors” means the total authorized number of Directors that the Corporation would have if there were no vacancies.

(3) Classified Board. Subject to the rights of holders of capital stock of the Corporation (other than the Common Stock) then outstanding, the Directors shall be divided into three classes, with respect to the time that they severally hold office, as nearly equal in number as possible, with the initial term of office of the first class of Directors to expire at the 2005 Annual Meeting of Stockholders, the initial term of office of the second class of Directors to expire at the 2006 Annual Meeting of Stockholders and the initial term of office of the third class of Directors to expire at the 2007 Annual Meeting of Stockholders. Commencing with the 2005 Annual Meeting of Stockholders, Directors elected to succeed those Directors whose terms have thereupon expired shall be elected for a term of office to expire at the third succeeding Annual Meeting of Stockholders after their election, and upon the election and qualification of their successors. A person elected as a Director shall be deemed a Director as of the time of such election. Subject to the rights of holders of capital stock of the Corporation (other than the Common Stock) then outstanding, if the number of Directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain or attain, if possible, an equal number of Directors in each class, but in no case will a decrease in the number of Directors shorten the term of any incumbent Director. If such equality is not possible, the increase or decrease shall be apportioned among the classes in such a way that the difference in the number of Directors in any two classes shall not exceed one.

(4) Vacancies. Subject to the rights of the holders of capital stock of the Corporation (other than the Common Stock) then outstanding, any vacancies in the Board of Directors for any reason and any newly created Directorships resulting by reason of any increase in the number of Directors shall, if occurring prior to the expiration of the term of office of the class in which such vacancy or increase occurs, be filled only by the Board of Directors, acting by the affirmative vote of a majority of the remaining Directors then in office, although less than a quorum and any Directors so elected shall hold office until the next election of the class for which such Directors have been elected and until their successors are elected and qualified.

(5) Removal of Directors. Subject to the rights of the holders of capital stock of the Corporation (other than the Common Stock) then outstanding, any Director, or the entire Board of Directors, may be removed from office at any time prior to the expiration of his or their term

of office, but only for cause and only by the affirmative vote of the holders of record of outstanding shares representing at least eighty percent (80%) of the voting power of all of the shares of capital stock of the Corporation then entitled to vote generally in the election of Directors, voting together as a single class.

ARTICLE IX

Whenever a compromise or arrangement is proposed between this Corporation and its creditors or any class of them and or between this Corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of this Corporation or of any creditor or stockholder thereof, or on the application of any receiver or receivers appointed for this Corporation under the provisions of section 291 of Title 8 of the Delaware Code or on the application of trustees in dissolution or of any receiver or receivers appointed for this Corporation under the provisions of section 279 of Title 8 of the Delaware Code order a meeting of the creditors or class of creditors, and/or of the stockholders or class of stockholders of this Corporation, as the case may be, to be summoned in such manner as the said Court directs. If a majority in number representing three-fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of this Corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of this Corporation as a consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the Court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of this Corporation, as the case may be, and also on this Corporation.

ARTICLE X

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 by law, and all rights and powers conferred herein on stockholders, directors and officers are subject to this reserved power; provided, however, that, notwithstanding the fact that a lesser percentage may be specified by the General Corporation Law of Delaware, the affirmative vote of the holders of record of outstanding shares representing at least two-thirds of the voting power of all of the shares of capital stock of the Corporation then entitled to vote generally in the election of Directors, voting together as a single class, shall be required to amend, alter, change, repeal or adopt any provision or provisions inconsistent with, Section (2) of Article V, Sections (2), (3) and (4) of Article VI, and Articles VIII, X, XI and XII of this Certificate of Incorporation unless such amendment, alteration, change, repeal or adoption of any inconsistent provision or provisions is declared advisable by the Board of Directors by the affirmative vote of at least two-thirds of the entire Board of Directors.

ARTICLE XI

No Director shall be personally liable to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty by such Director as a Director. Notwithstanding the

foregoing, a Director shall be liable to the extent provided by applicable law (i) for breach of the Director’s duty of loyalty to the Corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) pursuant to Section 174 of the General Corporation Law of Delaware; or (iv) for any transaction from which the Director derived an improper personal benefit. If the General Corporation Law of Delaware is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a Director of the Corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law of Delaware, as so amended. No amendment to or repeal of these provisions shall apply to or have any effect on the liability or alleged liability of any Director of the Corporation for or with respect to any acts or omissions of such Director occurring prior to such amendment or repeal.

ARTICLE XII

(1) No contract, agreement, arrangement or transaction (or any amendment, modification or termination thereof) entered into between the Corporation or any of its Affiliated Companies, on the one hand, and Kimberly-Clark Corporation, a Delaware corporation (“K-C”), or any of its Affiliated Companies, on the other hand, before the Corporation ceased to be a wholly owned subsidiary of K-C shall be void or voidable or be considered to be unfair to the Corporation for the reason that K-C or any of its Affiliated Companies, are parties thereto, or because directors or officers of K-C or any of its Affiliated Companies were present at or participated in any meeting of the Board of Directors or committee thereof which authorized the contract, agreement, arrangement or transaction (or the amendment, modification or termination thereof), or because his, her or their votes were counted for such purpose. No such contract, agreement, arrangement or transaction (or the amendment, modification or termination thereof) or the performance thereof by the Corporation or any of its Affiliated Companies shall be considered to be contrary to any fiduciary duty owed to the Corporation or to any stockholder of the Corporation by any director or officer of the Corporation or of any of its Affiliated Companies (including directors or officers of the Corporation or its Affiliated Companies who may have been directors or officers of K-C or any of its Affiliated Companies) and such directors and officers of the Corporation or any of its Affiliated Companies shall be deemed to have acted in good faith and in a manner such persons reasonably believe to be in or not opposed to the best interests of the Corporation and shall be deemed not to have breached their fiduciary duties to the Corporation or its stockholders, and not to have derived an improper personal benefit therefrom. No director, officer or employee of the Corporation or any of its Affiliated Companies shall have or be under any fiduciary duty to the Corporation to refrain from acting on behalf of the Corporation or any of its Affiliated Companies in respect of any such contract, agreement, arrangement or transaction (or the amendment, modification or termination thereof) or to refrain from performing any such contract, agreement, arrangement or transaction (or the amendment, modification or termination thereof) in accordance with its terms.

(2) Except as otherwise agreed in writing between the Corporation and K-C or as required by law, K-C shall have no duty to refrain from (i) engaging in the same or similar activities or lines of business as the Corporation and (ii) doing business with any client, customer or vendor of the Corporation, and neither K-C nor any officer, director or employee thereof shall

be deemed to have breached its, his or her fiduciary duties, if any, to the Corporation by reason of K-C’s engaging in any such activity.

(3) For purposes of this Article XII, “Affiliated Company” shall mean in respect of K-C, any company which is controlled by K-C, controls K-C or is under common control with K-C (other than the Corporation and any company that is controlled by the Corporation), and in respect of the Corporation shall mean any company controlled by the Corporation.

(4) Notwithstanding the foregoing, the amendment or removal of this Article XII shall not terminate the effect of (i) the provisions hereof with respect to any contract, agreement, arrangement or transaction (or the amendment, modification or termination thereof) between the Corporation or any of its Affiliated Companies, on the one hand, and K-C or any of its Affiliated Companies, on the other hand, that was entered into before the Corporation ceased to be a wholly owned subsidiary of K-C or (ii) Section 2 of this Article XII.

(5) Any person purchasing or otherwise acquiring any shares of capital stock of the Corporation, or any interest therein, shall be deemed to have notice of and to have consented to the provisions of this Article XII.

IN WITNESS WHEREOF, the Corporation has caused this Amended and Restated Certificate of Incorporation to be signed as of the date first set forth above.
