NINTH: (a) The corporation shall have power to 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 (other than an action by or in the right of the corporation) by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' 4 fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful. (b) The corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjusted to be liable for negligence or misconduct in the performance of his duty to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper. (c) To the extent that a director, officer, employee or agent of the corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b), or in defense of any claim, issue or matter therein, he shall be 5 indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith. (d) Any indemnification under subsections (a) and (b) (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in subsections (a) and (b). Such determination shall be made (1) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable a quorum is disinterested directors so directs, by independent legal counsel in a written opinion, or (3) by the stockholders.

Thereafter, by-laws may be made, and shall be subject to alteration and repeal, by the stockholders of the corporation, at any annual or special meeting, and by the board of directors at any regular or special meeting; provided, however, that by-laws made or altered by the board of directors may be altered or repealed by the stockholders at any annual or special meeting.

It is hereby certified that: 1. The name of the corporation (hereinafter called the "Corporation") is Danbury Pharmacal, Inc. 2. The Certificate of Incorporation of the Corporation is hereby amended by striking out Article FOURTH thereof and by substituting in lieu of said Article the following new Article FOURTH to read as follows: "FOURTH: The total number of shares of all classes of stock which the Corporation shall have authority to issue is 1,000,000 shares, which shall be divided into two classes consisting of 500,000 shares of Preferred Stock, par value $.10 per share (hereinafter referred to as "Preferred Stock") and 500,000 shares of Common Stock, par value $.10 per share (hereinafter referred to as "Common Stock"). 1 A. PREFERRED STOCK. (1) 150,000 shares of Preferred Stock are hereby constituted as a series of Preferred Stock designated as "Preferred Stock, Series A" (hereinafter referred to as "Series A Stock") with the powers, preferences and rights hereinafter set forth. (a) The holders of the Series A Stock shall be entitled to receive, with respect to each fiscal year of the Corporation during which any of the Series A Stock is outstanding, cash dividends out of the net profits realized by the Corporation during such fiscal year, and not to exceed an annual rate of $.02 per share, payable on the first day of July in the succeeding fiscal year, if, as and when declared by the Board of Directors, out of funds at the time legally available for the payment of dividends. Dividends on the Series A Stock, to the extent equal to the net profits realized by the Corporation as aforesaid, shall be cumulative and shall accrue from and after the date of issuance thereof. No dividends shall be declared, paid or set apart for payment on any other series of Preferred Stock or on Common Stock unless and until all dividends 2 on the Series A Stock that have accrued for all past dividend periods and the annual dividend on the Series A Stock for the current dividend period to the extent accrued shall have been paid or declared and a sum sufficient for the payment thereof set apart. (b) In the event of any liquidation, dissolution or winding up of the Corporation, before any payment or distribution of the assets of the Corporation (whether capital or surplus) shall be made to or set apart for the holders of any other series of Preferred Stock or of Common Stock, the holders of Series A Stock shall be entitled to receive payment of an amount equal to $.40 per share plus an amount equal to all unpaid cumulative dividends accrued thereon, pursuant to subparagraph (1)(a) hereof to the date of final distribution to such holders, and no more. If the assets of the Corporation, or the proceeds thereof available for distribution to its shareholders shall be insufficient to pay in full all amounts to which the holders of Series A Stock are entitled, then such assets or the proceeds thereof shall be distributed among such holders ratably in accordance with the respective amounts which would be payable on such shares if all amounts payable were paid in full. For the purposes of this sub-paragraph (1)(b), the voluntary sale, lease, exchange or transfer of all or substantially all of the Corporation's assets, or the consolidation or merger of the Corporation with or into any other 3 corporation shall not be deemed to be a liquidation, dissolution or winding up of the Corporation. (c) The Corporation may, at its option, at any time or from time to time, redeem the whole or any part of the Series A Stock at a redemption price equal to $.40 per share, plus an amount equal to all unpaid cumulative dividends accrued thereon, pursuant to subparagraph (1)(a) hereof, to the date of redemption. In the event the Corporation shall determine to redeem less than all of the shares of the Series A Stock then outstanding, the Board of Directors shall determine the shares of Series A Stock so to be redeemed by lot or pro rata or by any other means which the Board of Directors deems equitable. Notice of any proposed redemption of any Series A Stock shall be given by the Corporation by mailing a copy of such notice at least thirty (30) days prior to the date fixed for such redemption to the holders of record of the Series A Stock to be redeemed, at their respective addresses appearing on the books of the Corporation. If on the redemption date specified in such notice, the funds necessary for such redemption shall have been set aside by the Corporation, separate and apart from its other funds, in trust for the pro rata benefit of the holders of the shares so called for redemption, then, notwithstanding that any certificates for shares of Series A Stock so called for redemption shall not have been surrendered for cancellation, the shares represented there- 4 by shall no longer be deemed outstanding, all dividends thereon shall cease to accrue and all rights of the holders thereof as stockholders of the Corporation (except the right to receive payment of the redemption price and accrued and unpaid cumulative dividends to the date of redemption) shall cease and determine. (d) So long as any of the Series A Stock is outstanding the Corporation will not, without the affirmative vote or consent of the holders of at least 66 2/3% of the Series A Stock at the time outstanding, given in person or by proxy, either in writing or by resolution adopted at an annual meeting or a special meeting called for the purpose, (i) create any other class or series of stock ranking prior to, or on a parity with, the Series A Stock, either as to dividends or upon liquidation, or increase the authorized number of shares of any such other class or series of stock or of the Series A Stock, or (ii) amend, alter or repeal any of the provisions hereof so as adversely to affect the preferences, rights or powers of the Series A Stock. (e) Except as specifically provided in this subparagraph (1) or as otherwise required by law, no holder of the Series A Stock shall be entitled to any voting rights 5 or to receive notice of, or participate in, any meeting of stockholders. (2) Subject to the provisions of subparagraph (1) above, the designations, powers, preferences and rights in respect of shares of Preferred Stock other than shares of Series A Stock shall be as follows: Shares of Preferred Stock may be issued from time to time in one or more series, as may from time to time de determined by the Board of Directors, each of said series to be distinctly designated. All shares of any one series of Preferred Stock shall be alike in every particular, except that there may be different dates from which dividends, if any, thereon shall be cumulative, if made cumulative. The voting powers and the preferences and relative, participating, optional and other special rights of each such series, and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series at any time outstanding; and the Board of Directors of the Corporation is hereby expressly granted authority to fix by resolution or resolutions adopted prior to the issuance of any shares of a particular series of Preferred Stock, the voting powers and the designations, preferences and relative, optional and other special rights, and the qualifications, limitations and restrictions of such series, including, but without limiting 6 the generality of the foregoing, the following: (a) The distinctive designation of, and the number of shares of Preferred Stock which shall constitute such series, which number may be increased (except where otherwise provided by the Board of Directors) or decreased (but not below the number of shares thereof then outstanding) from time to time by like action of the Board of Directors; (b) The rate and times at which, and the terms and conditions on which, dividends, if any, on Preferred Stock of such series shall be paid, the extent of the preference or relation, if any, of such dividends to the dividends payable on any other class or classes, or series of the same or other classes of stock and whether such dividends shall be cumulative or non-cumulative; (c) The right, if any, of the holders of Preferred Stock of such series to convert the same into, or exchange the same for, shares of any other class or classes or of any series of the same or any other class or classes of stock of the Corporation and the terms and conditions of such conversion or exchange; 7 (d) Whether or not Preferred Stock of such series shall be subject to redemption, and the redemption price or prices and the time or times at which, and the terms and conditions on which, Preferred Stock of such series may be redeemed; (e) The rights, if any, of the holders of Preferred Stock of such series upon the voluntary or involuntary liquidation, merger, consolidation, distribution or sale of assets, dissolution or winding-up, of the Corporation; (f) The terms of the sinking fund or redemption or purchase account, if any, to be provided for the Preferred Stock of such series; and (g) The voting powers, if any, of the holders of such series of Preferred Stock which may, without limiting the generality of the foregoing, include the right, voting as a series by itself or together with other series of Preferred Stock or all series of Preferred Stock as a class, to elect one or more directors of the Corporation if there shall have been a default in the payment of dividends on any one or more series of Preferred Stock or under such other circumstances and on such conditions as the Board of Directors may determine; provided, 8 however, that each holder of Preferred Stock shall have no more than one vote in respect of each share of Preferred Stock held by him on any matter voted upon by the stockholders. B. COMMON STOCK: (1) After the requirements with respect to preferential dividends on the Preferred Stock (fixed in accordance with the provisions of Paragraph A of this Article Fourth), if any, shall have been met and after the Corporation shall have complied with all the requirements, if any, with respect to the setting aside of sums as sinking funds or redemption or purchase accounts (fixed in accordance with the provisions of Paragraph A of this Article Fourth), and subject further to any other conditions which may be fixed in accordance with the provisions of Paragraph A of this Article Fourth, then and not otherwise the holders of Common Stock shall be entitled to receive such dividends as may be declared from time to time by the Board of Directors. (2) After distribution in full of the preferential amount, if any (fixed in accordance with the provisions of Paragraph A of this Article Fourth), to be distributed to the holders of Preferred Stock in the event of voluntary or involuntary liquidation, distribution or sale of assets, dissolution or winding-up, of the Corporation, the holders of the Common Stock shall be entitled to receive all the remaining assets of the Corporation, tangible and intangible, of whatever kind available for distribution to stockholders ratably in proportion to the number of shares of Common Stock held by them respectively. (3) Except as may otherwise be required by law or by the provisions of such resolution or resolutions as may be adopted by the Board of Directors pursuant to Paragraph A of this Article Fourth, each holder of Common Stock shall have one vote in respect of each share of Common Stock held by him on al matters voted upon by the stockholders. C. OTHER PROVISIONS: (1) Subject to the provisions of subparagraph 1 of Paragraph A of this Article Fourth, the relative powers, preferences and rights of each series of Preferred Stock in relation to the powers, preferences and rights of each other series of Preferred Stock shall, in each case, be as fixed from time to time by the Board of Directors in the resolution or resolutions adopted pursuant to authority granted in Paragraph A of this Article Fourth and the consent, by class or series vote or otherwise, of the holders of such of the series of Preferred Stock as are from time to time outstanding shall not be required for the issuance by the Board of Directors of any other series of Preferred Stock whether or not the powers, preferences and rights of such other series shall be fixed by the Board of Directors as senior to, or on a parity with, the powers, preferences and rights of such outstanding series, or any of them; provided, however, that the Board of Directors may provide in the resolution or resolutions as to any series of Preferred Stock adopted pursuant to Paragraph A of this Article Fourth that the consent of the holders of a majority (or such greater proportion as shall be therein fixed) of the outstanding shares of such series voting thereon shall be required for the issuance of any or all other series of Preferred Stock. (2) Subject to the provisions of subparagraph 1 of this Paragraph C, shares of any series of Preferred Stock may be issued form time to time as the Board of Directors of the Corporation shall determine and on such terms and for such consideration as shall be fixed by the Board of Directors. (3) Shares of Common Stock may be issued from time to time as the Board of Directors of the Corporation shall determined and on such terms and for such consideration as shall be fixed by the Board of Directors. (4) The authorized amount of shares of Common Stock and of Preferred Stock may, without a class or series vote, be increased or decreased from time to time by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote thereon." 11 3.
