Exhibit 3.1 AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF DISCOVERY THERAPEUTICS, INC. (Originally incorporated April 4, 1994) Peter G. Savas and James V. Peck hereby certify that: ONE: They are the duly elected and acting President and Secretary, respectively, of Discovery Therapeutics, Inc., a Delaware corporation (the "Corporation"). TWO: The Certificate of Incorporation of the Corporation is hereby amended and restated to read as follows: "I. The name of this Corporation is Discovery Therapeutics, Inc. II. The address, including street, number, city, and county, of the registered office of the Corporation in the State of Delaware is 2711 Centerville Road, in the City of Wilmington, 19808, County of New Castle, and the name of the registered agent of the Corporation in the State of Delaware at such address is The Prentice-Hall Corporation System, Inc. III. The purpose of this Corporation is to engage in any lawful act or activity for which a corporation may be organized under the Delaware General Corporation Law IV. 1. This Corporation is authorized to issue two classes of stock to be designated "Common Stock" and "Preferred Stock", respectively. The total number of shares which the Corporation is authorized to issue is Seventeen Million (17,000,000) shares. Ten Million (10,000,000) shares shall be Common Stock, each having a par value of One-Tenth of One Cent ($0.001). Seven Million (7,000,000) shares shall be Preferred Stock, each having a par value of One-Tenth of One Cent ($0.001). 2. The Preferred Stock may be issued from time to time in one of more series. The Board of Directors is hereby authorized, by filing a certificate pursuant to the Delaware General Corporation Law, to fix or alter from time to time the designations, powers, preferences and rights of the shares of each such series and the qualifications, limitations or restrictions thereof, including without limitation the dividend rights, dividend rate, conversion rights, voting rights, rights and terms of redemption (including sinking fund provisions), redemption price or prices, and the liquidation preferences of any wholly owned unissued series of Preferred Stock, and to establish from time to time the number of shares constituting any such series and designation thereof, of any of them (a "Preferred Stock Designation"); and to increase or decrease the number of shares of any series subsequent to the issuance of shares of that series, but not below the number of shares of such series then outstanding. In case the number of shares of any series shall be so decreased, the shares constituting such decrease shall resume the status that they had prior to the adoption of the resolution originally fixing the number of shares of such series. 3. Designation of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock. Six Hundred Sixty-Six Thousand Six Hundred Sixty-Seven (666,667) shares of Preferred Stock are designated Series A Preferred Stock ("Series A Preferred"), One Million Five Hundred Thousand (1,500,000) shares of Preferred Stock are designated "Series B Preferred Stock" ("Series B Preferred"), Five Hundred Thirty-Eight Thousand Seven Hundred Seventy Six (538,776) shares of Preferred Stock are designated "Series C Preferred Stock" ("Series C Preferred"), and Two Million Eight Hundred Thousand (2,800,000) shares of Preferred Stock are designated "Series D Preferred Stock" ("Series D Preferred"). The Series A Preferred, the Series B Preferred, the Series C Preferred and the Series D Preferred (collectively "Preferred") shall have the rights, preferences and privileges specified herein. "Original Issuance Price" shall refer to $0.75 in the case of each share of Series A Preferred, $6.00 in the case of each share of Series B Preferred, $10.21 in the case of each share of Series C Preferred, and $11.00 in the case of each share of Series D Preferred. 4. Dividend Rights of Preferred. The holders of outstanding Preferred shall be entitled to receive in any fiscal year, when and as declared by the Board of Directors, out of any assets at the time legally available therefor, dividends in cash at an annual rate of $0.06 per share of Series A Preferred, $0.48 per share of Series B Preferred, $0.82 per share of Series C Preferred, and $0.88 per share of Series D Preferred. Such dividends may be payable quarterly or otherwise as the Board of Directors may from time to time determine. The right to such dividends shall not be cumulative and no right shall accrue to holders of Preferred by reason of the fact that dividends on such shares were not declared in any prior year, nor shall any undeclared or unpaid dividends bear or accrue interest. No dividend shall be paid on or declared and set apart for the shares of any series of Preferred for any dividend period unless at the same time a like proportionate dividend for the same dividend period, ratably in proportion to the respective annual dividend rates fixed therefor, shall be paid on or declared and set apart for the shares of all other such series of Preferred. Dividends other than dividends payable solely in Common Stock may be declared or paid upon shares of Common Stock in any fiscal year of the Corporation only if dividends at the annual rates set forth above shall have been paid or declared and set apart for all shares of Preferred for such fiscal year. No dividend shall be declared or paid with respect to the Common Stock unless at the same time an equivalent dividend is declared or paid with respect to the Preferred, assuming the conversion of each series of the Preferred into Common Stock at the then applicable Conversion Price for each series, as set forth in Section 6 below. 5. Liquidation Preference. (a) In the event of any liquidation, dilution or winding up of the Corporation and until all preferential amounts owed to them under this subsection (a) have been paid, (i) the holders of the Series A Preferred, Series B Preferred, and Series D Preferred shall be entitled to receive, prior and in preference to any distribution of any asset or property of the Corporation to 2 the holders of Common Stock or of Series C Preferred by reason of their ownership thereof, the amount of $0.75 per share for each share of Series A Preferred, $6.00 per share for each share of Series B Preferred, and $11.00 per share for each share of Series D Preferred then held by them, plus an amount equal to all declared but unpaid dividends on the Series A Preferred, Series B Preferred, and Series D Preferred as of the liquidation date (each as adjusted for stock splits, combinations and similar events with respect to the Series A Preferred, Series B Preferred, and Series D Preferred): and (ii) after the payment in full of the preferred amounts pursuant to the immediately preceding clause (i), the holders of the Series C Preferred shall be entitled to receive, prior and in preference to any distribution of any asset or property of the Corporation to the holders of Common Stock by reason of their ownership thereof, the amount of $10.21 per share for each share of Series C Preferred then held by them, plus an amount equal to all the declared but unpaid dividends on the Series C Preferred as of the liquidation date (each as adjusted for stock splits, combinations and similar events with respect to the Series C Preferred). If upon any liquidation, distribution, or winding up of the Corporation, the assets of the Corporation shall be insufficient to make payment in full of such amounts to all holders of the Series A Preferred, Series B Preferred, and Series D Preferred due under clause (i), then such assets shall be distributed among such holders ratably in proportion to the full amounts to which they would otherwise be entitled. If upon any liquidation, distribution, or winding up of the Corporation, the assets of the Corporation shall be insufficient to make payment in full of such amounts to all holders of the Series C Preferred due under clause (ii), then such assets shall be distributed among such holders ratably in proportion to the full amounts to which they would otherwise be entitled. (b) After the payment of the full liquidation preference of the Series A Preferred, Series B Preferred, Series C Preferred, and Series D Preferred as set forth in Section 5(a) above, the remaining assets of the Corporation, if any, shall be distributed ratably among the holders of Common Stock and the Series A Preferred, Series B Preferred, and Series D Preferred in proportion to the number of shares held by them, assuming the conversion of each such share of Series A Preferred, Series B Preferred, and Series D Preferred into Common Stock at the then applicable Conversion Price for each such series, as set forth in Section 6 below. (c) A merger, share exchange, reorganization, acquisition or sale of voting control (in each case in which the stockholders of the Corporation do not own a majority of the outstanding shares of the surviving corporation) or sale of all or substantially all of the assets of the Corporation shall be considered a liquidation under this Section 5 (together with any liquidation, dissolution or winding up of the Corporation, a "Liquidation Event"). 6. Conversion Rights. The holders of Preferred shall have conversion rights as follows (the "Conversion Rights"): (a) Each share of Series A Preferred shall be convertible, without the payment of any additional consideration by the holder thereof and at the option of the holder thereof, at any time after the date of issuance of such share, at the office of the Corporation or any transfer agent for the Series A Preferred, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing $.75 by the Series A Conversion Price, determined as hereinafter provided and in effect at the time of the conversion. Each share of Series B 3 Preferred shall be convertible, without the payment of any additional consideration by the holder thereof and at the option of the holder thereof, at any time after the date of the issuance of such share, at the office of the Corporation or any transfer agent for the Series B Preferred, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing $6.00 by the Series B Conversion Price, determined as hereinafter provided and in effect at the time of the conversion. Each share of Series C Preferred shall be convertible, without the payment of any additional consideration by the holder thereof and at the option of the holder thereof, at any time after the date of the issuance of such share, at the office of the Corporation or any transfer agent for the Series C Preferred, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing $10.21 by the Series C Conversion Price, determined as hereinafter provided and in effect at the time of the conversion. Each share of Series D Preferred shall be convertible, without the payment of any additional consideration by the holder thereof and at the option of the holder thereof, at any time after the date of the issuance of such share, at the office of the Corporation or any transfer agent for the Series D Preferred, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing $11.00 by the Series D Conversion Price, determined as hereinafter provided and in effect at the time of the conversion. The price at which shares of Common Stock shall be deliverable upon conversion of the Series A Preferred without payment of any additional consideration by the holder thereof (the "Series A Conversion Price") shall initially be $.75 per share of Common Stock, the price at which shares of Common Stock shall be deliverable upon conversion of the Series B Preferred without the payment of any additional consideration by the holder thereof (the "Series B Conversion Price") shall initially be $6.00 per share of Common Stock, the price at which shares of Common Stock shall be deliverable upon conversion of the Series C Preferred without the payment of any additional consideration by the holder thereof (the "Series C Conversion Price") shall initially be $10.21 per share of Common Stock, and the price at which shares of Common Stock shall be deliverable upon conversion of the Series D Preferred without the payment of any additional consideration by the holder thereof (the "Series D Conversion Price") shall initially be $11.00 per share of Common Stock. The term Conversion Price as used herein shall, unless otherwise specified, refer to the respective conversion price for each share of Series A Preferred, Series B Preferred, Series C Preferred and Series D Preferred. Each such initial Conversion Price shall be subject to adjustment, as hereinafter provided, in order to adjust the number of shares of Common Stock into which Preferred is convertible. (b) Automatic Conversion. Each share of Preferred shall automatically be converted into Shares of Common Stock at the then effective Conversion Price in the event of either: (i) Upon approval by holders of more than 50% of the then outstanding shares of Preferred voting together as a single class; or (ii) The closing (the "Closing") of a firm commitment underwritten public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended (the "Securities Act"), covering the offer and sale of Common Stock for the account of the Corporation to the public at a public offering price of at least Fifteen Dollars ($15.00) per share, subject to adjustment for any subdivisions, combinations or consolidations of the Common Stock from time to time, and having an aggregate offering price greater than Twenty Five 4 Million Dollars ($25,000,000). In the event of such an offering, the person(s) entitled to receive Common Stock issuable upon such conversion of Preferred shall not be deemed to have converted their Preferred until immediately prior to the Closing. (c) Mechanics of Conversion. No fractional shares of Common Stock shall be issued upon conversion of Preferred. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the then effective Conversion Price of the appropriate series of Preferred. Before any holder of Preferred shall be entitled to convert the same into shares of Common Stock pursuant to Section 6(a) hereof, he shall surrender the certificate or certificates therefor, duly endorsed, at the office of the Corporation or of any transfer agent for Preferred, and shall give written notice to the Corporation at such office that he elects to convert the same and shall state therein his name or the name or names of his nominees in which he wishes the certificate or certificates for shares of Common Stock to be issued. The Corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Preferred, or to his nominee or nominees, a certificate or certificates for the number of shares of Common Stock to which he shall be entitled as aforesaid, together with cash in lieu of any fraction of a share. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Preferred to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock on such date. (d) Adjustments to Conversion Price for Dilutive Issues. (i) Special Definitions. For purposes of this Section 6(d), the following definitions shall apply: (1) "Option" shall mean rights, options or warrants to subscribe for, purchase, or otherwise acquire either Common Stock or Convertible Securities (as hereinafter defined). (2) "Original Issue Date" shall mean the date that the first share of Series B Preferred was issued. (3) "Convertible Securities" shall mean any evidences of indebtedness, shares (other than Common Stock and Preferred authorized herein) or other securities convertible into or exchangeable for, directly or indirectly, Common Stock. (4) "Additional Shares of Common Stock" shall mean all shares of Common Stock issued (or, pursuant to Section 6(d)(iii), deemed to be issued) by the Corporation after the Original Issue Date, other than: (A) shares of Common Stock issued or issuable upon conversion of shares of Preferred; or (B) shares of Common Stock issued or issuable to officers, directors and employees of, and consultants to, the Corporation pursuant to stock purchase or option plans or arrangements or other officer, director, employee or consultant stock 5 incentive or benefit plans or arrangements (collectively, the "Plans") approved by the Board of Directors covering an aggregate, at any time on or after the Original Issue Date, of not more than 1,000,000 shares of Common Stock, net of repurchases and option cancellations, subject to adjustment for any subdivisions, combinations or consolidations of Common Stock from time to time; or (C) shares of Common Stock issued or issuable as a dividend or distribution on Preferred; or (D) shares of Common Stock issued or issuable by way of dividend or other distribution on shares of Common Stock excluded from the definition of Additional Shares of Common Stock by the foregoing clauses(s) (A), (B), (C) or this clause (D); or (E) shares of Common stock issued or issuable upon cancellation of those certain promissory notes in the aggregate principal amount of $3,000,000 issued by the Company on July 23, 1996, August 22, 1996, November 14, 1996 and December 13, 1996. (ii) No Adjustment of Conversion Price. No adjustment in the number of shares of Common Stock into which the Series A Preferred, Series B Preferred, Series C Preferred and Series D Preferred is convertible shall be made pursuant to Section 6(d)(iv), by adjustment in the Conversion Price of such Preferred in respect of the issuance of Additional Shares of Common Stock or otherwise, unless the consideration per share for an Additional Share of Common Stock issued by the Corporation is less than the applicable Series A Conversion Price, Series B Conversion Price, Series C Conversion Price or Series D Conversion Price in effect on the date of, and immediately prior to, the issuance of such Additional Shares of Common Stock. (iii) Issue of Securities Deemed Issued of Additional Shares of Common Stock. (1) Options and Convertible Securities. In the event the Corporation at any time or from time to time after the Original Issue Date shall issue any Options or Convertible Securities or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of shares (as set forth in the instrument relating thereto without regard to any provisions contained therein for a contingent subsequent adjustment of such number) of Common Stock issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as of the time of the issuance of such Options or Convertible Securities or, in the case such a record date shall have been fixed, as of the close of business on such record date, provided that Additional Shares of Common Stock shall not be deemed to have been issued unless the consideration per share determined pursuant to Section 6(d)(v) hereof of such Additional Shares of Common Stock would be less than the applicable Conversion Price in effect on the date of and immediately prior to such issue, or such 6 record date, as the case may be, and provided further that in any such case in which Additional Shares of Common Stock are deemed to be issued: (A) no further adjustment in the Conversion Price shall be made upon the subsequent issue of Convertible Securities or shares of Common Stock upon the exercise of such Options or conversion or exchange of such Convertible Securities; (B) if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any increase in the consideration payable to the Corporation, or decrease in the number of shares of Common Stock upon the exercise, conversion or exchange thereof, the Conversion Price computed upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any increase or decrease becoming effective, be recomputed to reflect such increase or decrease insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities; (C) upon the expiration of such Options or any rights of conversion or exchange under such Convertible Securities which shall not have been exercised, the Conversion Price computed upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon such expiration, be recomputed as if: (I) in the case of Convertible Securities or Options for Common Stock, the only Additional Shares of Common Stock issued were the shares of Common Stock, if any, actually issued upon the exercise of such Options or the conversion or exchange of such Convertible Securities and the consideration received therefor was the consideration actually received by the Corporation for the issue of all such Options, whether or not exercised, plus the consideration actually received by the Corporation upon such exercise, or for the issue of all such Convertible Securities which were actually converted or exchanged, plus the additional consideration, if any, actually received by the Corporation upon such conversion or exchange, and (II) in the case of Options for Convertible Securities, only the Convertible Securities, if any, actually issued upon the exercise thereof were issued at the time of issue of such Options and the consideration received by the Corporation for the Additional Shares of Common Stock deemed to have been then issued was the consideration actually received by the Corporation for the issue of all such Options, whether or not exercised, plus the consideration deemed to have been received by the Corporation (determined pursuant to Section 6(d)(v)) upon the issue of the Convertible Securities with respect to which such Options were actually exercised; (D) no readjustment pursuant to clause (B) or (C) above shall have the effect of increasing the Conversion Price to an amount which exceeds the lower of (i) the Conversion Price on the original adjustment date, or (ii) the Conversion Price that would have resulted from any issuance of Additional Shares of Common Stock between the original adjustment date and such readjustment date; 7 (E) in the case of any Options which expire by their terms not more than thirty (30) days after the date of issue thereof, no adjustment of the Conversion Price shall be made until the expiration or exercise of all such Options, whereupon such adjustment shall be made in the same manner provided in clause (C) above; and (F) if such record date shall have been fixed and such Options or Convertible Securities are not issued on the date fixed thereof, the adjustment previously made in the Conversion Price which became effective on such record date shall be canceled as of the close of business on such record date, and thereafter the Conversion Price shall be adjusted pursuant to this Section 6(d)(iii) as of the actual date of their issuance. (2) Stock Dividends, Stock Distributions and Subdivisions. In the event the Corporation at any time or from time to time after the Original Issue Date shall declare or pay any dividend or make any other distribution on Common Stock payable in Common Stock, or effect a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in Common Stock), then and in any such event, Additional Shares of Common Stock shall be deemed to have been issued: (A) in the case of any such dividend or distribution, immediately after the close of business on the record date for the determination of holders of any class of securities entitled to receive such dividend or distribution; or (B) in the case of any such subdivision, at the close of business on the date immediately prior to the date upon which such corporate action becomes effective. If such record date shall have been fixed and such dividend shall not have been fully paid on the date fixed therefor, the adjustment previously made in the Conversion Price which became effective on such record date shall be canceled as of the close of business on such record date, and thereafter the Conversion Price shall be adjusted pursuant to this Section 6(d)(iii) as of the time of actual payment of such dividend. (iv) Adjustment of Conversion Price Upon Issuance of Additional Shares of Common Stock. In the event the Corporation shall issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to paragraph 6(d)(iii), but excluding Additional Shares of Common Stock issued pursuant to paragraph 6(d)(iii)(2) which event is dealt with in paragraph 6(d)(vi) hereof), and if such Additional Shares of Common Stock are issued without consideration or for a consideration per share less than the Series A Conversion Price, Series B Conversion Price, Series C Conversion Price or Series D Conversion Price in effect on the date of and immediately prior to such issue, then in such event, the Series A Conversion Price, Series B Conversion Price, Series C Conversion Price and/or Series D Conversion Price, as the case may be, shall be reduced, concurrently with such issue, to a price, calculated to the nearest one-tenth of one cent, determined by multiplying such Conversion Price by a fraction: (1) the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of shares of 8 Common Stock which the aggregate consideration received by the Corporation for the total number of Additional Shares of Common Stock so issued would purchase at such Conversion Price; and (2) the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of such Additional Shares of Common Stock so issued; provided, however, that, for the purpose of this paragraph 6(d)(iv) only, all shares of Common Stock issuable upon conversion of outstanding Options and Convertible Securities (including the Series A Preferred, Series B Preferred, Series C Preferred and Series D Preferred) shall be deemed to be outstanding, and, immediately after any Additional Shares of Common Stock are deemed issued pursuant to paragraph 6(d)(iii), such Additional Shares of Common Stock shall be deemed to be outstanding. (v) Determination of Consideration. For purposes of this Section 6(d), the consideration received by the Corporation for the issue of any Additional Shares of Common Stock shall be computed as follows: (1) Cash and Property: Such consideration shall: (A) insofar as it consists of cash, be computed at the aggregate amount of cash received by the Corporation, excluding amounts paid or payable for accrued interest or accrued dividends; (B) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board of Directors; and (C) in the event Additional Shares of Common Stock are issued together with other shares or securities or other assets of the Corporation for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (A) and (B) above, as determined in good faith by the Board of Directors. (2) Options and Convertible Securities. The consideration per share received by the Corporation for Additional Shares of Common Stock deemed to have been issued pursuant to Section 6(d)(iii)(1), relating to Options and Convertible Securities, shall be determined by dividing (x) the total amount, if any, received or receivable by the Corporation as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Corporation upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such options for Convertible Securities and the conversion or exchange of such Convertible Securities, by (y) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities. 9 (vi) Adjustments for Stock Dividends, Subdivisions, Combinations or Consolidations of Common Stock. In the event the outstanding shares of Common Stock shall be subdivided (by stock split or otherwise), into a greater number of shares of Common Stock, or in the event the Corporation shall issue Additional Shares of Common Stock in a stock dividend, the Conversion Price for any series of Preferred then in effect shall, concurrently with the effectiveness of such subdivision or stock dividend, be proportionately decreased. In the event the outstanding shares of Common Stock shall be combined or consolidated, by reclassification or otherwise, into a lesser number of shares of Common Stock, the Conversion Price for any series of Preferred then in effect shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased. (vii) Adjustments for Other Distributions. In the event the Corporation at any time or from time to time makes or fixes a record date for the determination of holders of Common Stock entitled to receive any distribution payable in securities of the Corporation other than shares of Common Stock, then and in each such event provision shall be made so that the holders of Preferred shall receive upon conversion thereof, in addition to the number of shares of Common Stock receivable thereupon, the amount of securities of the Corporation which they would have received had their Preferred been converted into Common Stock on the date of such event and had they thereafter, during the period from the date of such event to and including the date of conversion, retained such securities receivable by them as aforesaid during such period, subject to all other adjustments called for during such period under this Section 6 with respect to the rights of the holders of the Preferred. (viii) Adjustment for Reclassification, Exchange and Substitution. If the Common Stock issuable upon the conversion of the Preferred is changed into the same or a different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise (other than a subdivision, combination or consolidation of shares or stock dividend or a reorganization, merger, consolidation or sale of assets provided for elsewhere in this Section 6 or in Section 5), in any such event each holder of Preferred shall have the right thereafter to convert such stock into the kind and the amount of stock and other securities and property receivable upon such recapitalization, reclassification or other change by holders of the maximum number of shares of Common Stock into which such shares of Preferred could have been converted immediately prior to such recapitalization, reclassification or change, all subject to further adjustment as provided herein or with respect to such other securities or property by the terms thereof. (ix) Reorganization, Mergers, Consolidations, Share Exchanges or Sales of Assets. If there is a capital reorganization of the Common Stock, merger, consolidation, share exchange or sale of assets of the Company ("Capital Reorganization") (other than a recapitalization, subdivision, combination, reclassification, exchange or substitution of shares provided for elsewhere in this Section 6 or in Section 5), as a part of such Capital Reorganization, provision shall be made so that the holders of Preferred shall thereafter be entitled to receive upon conversion of the Preferred the number of shares of stock or other securities or property of the Corporation (including cash) to which a holder of the number of shares of Common Stock deliverable upon conversion would have been entitled on such Capital Reorganization, subject to adjustment in respect of such stock or securities by the terms thereof. In any such case, appropriate adjustment shall be made in the application of the provisions of this 10 Section 6 with respect to the rights of the holders of Preferred after the Capital Reorganization to the end that the provisions of this Section 6 (including adjustment of the Conversion Price then in effect and the number of shares issuable upon conversion of the Preferred) shall be applicable after that event and be as nearly equivalent as practicable. (e) No Impairment. The Corporation will not, by amendment of this Amended and Restated Certificate of Incorporation or otherwise, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation but will at all times to good faith assist in the carrying out of all the provisions of this Section 6 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of Preferred against impairment: (f) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of any Conversion Price pursuant to this Section 6, the Corporation, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Preferred a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the written request at any time of any holder of Preferred, furnish or cause to be furnished to such holder a like certificate setting forth (i) such adjustments and readjustments, (ii) the Conversion Price for such series of Preferred at the time in effect and (iii) the number of shares of Common Stock and the amount, if any, of other property which at the time would be received upon the conversion of Preferred. (g) Notices of Record Date. In the event that this Corporation shall propose at any time: (i) to declare any dividend or distribution upon its Common Stock, whether in cash, property, stock or other securities, whether or not a regular cash dividend and whether or not out of earnings or earned surplus; (ii) to offer for subscription pro rata to the holders of any class or series of its stock any additional shares of stock of any class or series or other rights; (iii) to effect any reclassification or recapitalization of its outstanding Common Stock involving a change in the Common Stock; or (iv) to merge or consolidate with or into any other corporation, or sell, lease or convey all or substantially all its property or business, or to liquidate, dissolve or wind up; then, in connection with each such event, this Corporation shall send to the holders of Preferred: (1) at least 10 days' prior written notice of the date on which a record shall be taken for such dividend, distribution or subscription rights (and specifying the date an which the holders of Common Stock shall be entitled thereto) or for determining rights to vote in respect of the matters referred to in (iii) and (iv) above; and (2) in the case of matters referred to in (iii) and (iv) above, at least 10 days' prior written notice of the date when the same shall take place (and specifying, if 11 practicable, or estimating the date on which the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon the occurrence of such event). Each such written notice shall be given by first class mail, postage prepaid, addressed to the holders of Preferred at the address for each such holder as shown on the books of this Corporation. (h) Common Stock Reserved. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purposes of effecting the conversion of the shares of Preferred, such number of shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Preferred, and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of Preferred, the Corporation shall take such corporate action as may, is the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purpose. 7. Voting Rights. (a) Except as otherwise provided herein or as required by law, each share of Common Stock issued and outstanding shall have one vote, each share of Preferred issued and outstanding shall have the number of votes equal to the number of shares of Common Stock into which such share of Preferred is convertible as adjusted from time to time pursuant to Section 6 hereof, and the Common Stock and the Preferred shall vote together as a single class. Fractional votes by the holders of Preferred shall not, however, be permitted, and any fractional voting rights resulting from the above formula (after aggregating all shares into which shares of Preferred held by each holder could be converted) shall be rounded down. (b) The holders of shares of Series A Preferred, voting together as a separate class, shall be entitled to elect one director of the Corporation and to exercise any right of removal or replacement of such director, the holders of shares of Series B Preferred, voting together as a separate class, shall be entitled to elect one director of the Corporation and to exercise any right of removal or replacement of such director and the holders of shares of Preferred and Common Stock, voting together in accordance with Section 7(a) above, shall be entitled to elect any retraining directors and to exercise any right of replacement or removal of such directors.

No stockholder, however, may cumulate such stockholder's votes for one or more candidates unless (i) the names of such candidates have been properly placed in nomination, in accordance with the Bylaws of the Corporation, prior to the voting, (ii) the stockholder has given advance notice to the Corporation of the intention to cumulate votes 13 pursuant to the Bylaws, and (iii) the stockholder has given proper notice to the other stockholders at the meeting, prior to voting, of such stockholder's intention to cumulate such stockholder's votes.
