(c) Notwithstanding paragraphs (a) and (b) of this Section 3.2, the Warrantholder may require the Company to issue to the Warrantholder a Warrant or a stock certificate for Warrant Shares, in each case without a legend, if either (i) the resale of such Warrant or such Warrant Shares, as the case may be, has been registered under the Securities Act or (ii) the Warrantholder has delivered to the Company an opinion of legal counsel, which opinion shall be addressed to the Company and be reasonably satisfactory in form and substance to the Company, to the effect that such registration is not required with respect to the resale of such Warrant or such Warrant Shares, as the case may be. 4. Reservation and Registration of Shares, Etc. The Company covenants and agrees as follows: (a) all Warrant Shares which are issued upon the exercise of this Warrant will, upon issuance, be validly issued, fully paid, and nonassessable, not subject to any preemptive rights, and free from all taxes, liens, security interests, charges, and other encumbrances with respect to the issue thereof; (b) at its next shareholders meeting, the Company will seek shareholder approval to amend the Certificate of Incorporation to increase the number of shares of authorized Common Stock by a number sufficient for it to reserve, and the Company covenants that it will, immediately following receipt of such shareholder approval, reserve and keep available out of its authorized Common Stock, a sufficient number of shares for the purposes of issuance upon exercise of this Warrant; and 5 (c) the Company will, from time to time, take all such action as may be required to assure that the par value per share of the Warrant Shares is at all times equal to or less than the then effective Exercise Price. 5. Loss or Destruction of Warrant. Subject to the terms and conditions hereof, upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, of such bond or indemnification as the Company may reasonably require, and, in the case of such mutilation, upon surrender and cancellation of this Warrant, the Company will execute and deliver a new Warrant of like tenor. 6. Ownership of Warrant. The Company may deem and treat the Person in whose name this Warrant is registered as the holder and owner hereof (notwithstanding any notations of ownership or writing hereon made by anyone other than the Company) for all purposes and shall not be affected by any notice to the contrary, until presentation of this Warrant for registration of transfer in accordance with the restrictions on transfer set forth herein. 7. Certain Adjustments 7.1 The number of Warrant Shares purchasable upon the exercise of this Warrant and the Exercise Price shall be subject to adjustment as follows: (a) Stock Dividends. If at any time after the date of the issuance of this Warrant (i) the Company shall fix a record date for the issuance of any stock dividend payable in shares of Common Stock; or (ii) the number of shares of Common Stock shall have been increased by a subdivision or split-up of shares of Common Stock, then, on the record date fixed for the determination of holders of Common Stock entitled to receive such dividend or immediately after the effective date of such subdivision or split-up, as the case may be, the number of shares to be delivered upon exercise of this Warrant will be increased so that the Warrantholder will be entitled to receive the number of shares of Common Stock that the Warrantholder would have owned immediately following such action had this Warrant been exercised immediately prior thereto, and the Exercise Price will be adjusted as provided below in paragraph (g). 6 (b) Combination of Stock. If the number of shares of Common Stock outstanding at any time after the date of the issuance of this Warrant shall have been decreased by a combination of the outstanding shares of Common Stock, then, immediately after the effective date of such combination, the number of shares of Common Stock to be delivered upon exercise of this Warrant will be decreased so that the Warrantholder thereafter will be entitled to receive the number of shares of Common Stock that the Warrantholder would have owned immediately following such action had this Warrant been exercised immediately prior thereto, and the Exercise Price will be adjusted as provided below in paragraph (g). (c) Reorganization, etc. If any capital reorganization of the Company, any reclassification of the Common Stock, any consolidation of the Company with or merger of the Company with or into any other Person, or any sale or lease or other transfer of all or substantially all of the assets of the Company to any other Person, shall be effected in such a way that the holders of Common Stock shall be entitled to receive stock, other securities or assets (whether such stock, other securities or assets are issued or distributed by the Company or another Person) with respect to or in exchange for Common Stock, then, upon exercise of this Warrant, the Warrantholder shall have the right to receive the kind and amount of stock, other securities or assets receivable upon such reorganization, reclassification, consolidation, merger or sale, lease or other transfer by a holder of the number of shares of Common Stock that the Warrantholder would have been entitled to receive upon exercise of this Warrant had this Warrant been exercised immediately before such reorganization, reclassification, consolidation, merger or sale, lease or other transfer, subject to adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 7. If the Company effects any such consolidation, merger or sale, lease or other transfer, the Company shall ensure that prior to, or simultaneously with, the consummation thereof, the successor Person (if other than the Company) resulting from such consolidation or merger, or such Person purchasing, leasing or otherwise acquiring such assets, shall assume, by written instrument, the obligation to deliver to the Warrantholder the shares of stock, securities or assets to which, in accordance with the foregoing provisions, the Warrantholder may be entitled and all other obligations of the Company under this Warrant. The provisions of this paragraph (c) shall apply to successive 7 reorganizations, reclassifications, consolidations, mergers, sales, leasing transactions and other transfers. (d) Distributions to all holders of Common Stock. If the Company shall, at any time after the date of issuance of this Warrant, fix a record date to distribute to all holders of its Common Stock any shares of capital stock of the Company (other than Common Stock) or evidences of its indebtedness or assets (not including regular cash dividends and distributions paid from retained earnings of the Company) or rights or warrants to subscribe for or purchase any of its securities, then the Warrantholder shall be entitled to receive, upon exercise of this Warrant, that portion of such distribution to which it would have been entitled had the Warrantholder exercised its Warrant immediately prior to the date of such distribution. At the time it fixes the record date for such distribution, the Company shall allocate sufficient reserves to ensure the timely and full performance of the provisions of this Subsection. The Company shall promptly (but in any case no later than five Business Days prior to the record date of such distribution) give notice to the Warrantholder that such distribution will take place. (e) Fractional Shares. No fractional shares of Common Stock or scrip shall be issued to the Warrantholder in connection with the exercise of this Warrant. Instead of any fractional shares of Common Stock that would otherwise be issuable to the Warrantholder, the Company will pay to the Warrantholder a cash adjustment in respect of such fractional interest in an amount equal to that fractional interest of the then current Fair Market Value per share of Common Stock. (f) Carryover. Notwithstanding any other provision of this Section 7, no adjustment shall be made to the number of shares of Common Stock to be delivered to the Warrantholder (or to the Exercise Price) if such adjustment represents less than 0.10% of the number of shares to be so delivered, but any lesser adjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which together with any adjustments so carried forward shall amount to 0.10% or more of the number of shares to be so delivered. (g) Exercise Price Adjustment. Whenever the number of Warrant Shares purchasable upon the exercise of this Warrant is adjusted, as herein provided, the Exercise Price payable upon the exercise of this Warrant shall be adjusted by multiplying 8 such Exercise Price immediately prior to such adjustment by a fraction, of which the numerator shall be the number of Warrant Shares purchasable upon the exercise of the Warrant immediately prior to such adjustment, and of which the denominator shall be the number of Warrant Shares purchasable immediately thereafter. 7.2 Rights Offering. In the event the Company shall effect an offering of Common Stock pro rata among its stockholders, the Warrantholder shall be entitled to elect to participate in each and every such offering as if this Warrant had been exercised immediately prior to each such offering. The Company shall promptly (but in any case no later than five Business Days prior to such rights offering) give notice to the Warrantholder that such rights offering will take place. The Company shall not be required to make any adjustment with respect to the issuance of shares of Common Stock pursuant to a rights offering in which the holder hereof elects to participate under the provisions of this Section 7.2. 7.3 Notice of Adjustments. Whenever the number of Warrant Shares or the Exercise Price of such Warrant Shares is adjusted, as herein provided, the Company at its expense shall promptly give to the Warrantholder notice of such adjustment or adjustments and a certificate of the independent public accountants regularly employed by the Company or a firm of independent public accountants of recognized national standing selected by the Board of Directors of the Company (which shall be appointed at the Company's expense) setting forth the number of Warrant Shares and the Exercise Price of such Warrant Shares after such adjustment, a brief statement of the facts requiring such adjustment, and the computation by which such adjustment was made. 7.4 Notice of Extraordinary Corporate Events. In case the Company after the date hereof shall propose to (i) distribute any dividend (whether stock or cash or otherwise) to the holders of shares of Common Stock or to make any other distribution to the holders of shares of Common Stock, (ii) offer to the holders of shares of Common Stock rights to subscribe for or purchase any additional shares of any class of stock or any other rights or options, or (iii) effect any reclassification of the Common Stock (other than a reclassification involving merely the subdivision or combination of outstanding shares of Common Stock), any capital reorganization, any consolidation or merger (other than a merger in which no distribution of securities or other property is to be made to holders of shares of Common Stock), any sale or lease or transfer or other 9 disposition of all or substantially all of its property, assets and business, or the liquidation, dissolution or winding up of the Company, then, in each such case, the Company shall give to the Warrantholder notice of such proposed action, which notice shall specify the date on which (a) the books of the Company shall close, or (b) a record shall be taken for determining the holders of Common Stock entitled to receive such stock dividends or other distribution or such rights or options, or (c) such reclassification, reorganization, consolidation, merger, sale, transfer, other disposition, liquidation, dissolution or winding up shall take place or commence, as the case may be, and the date, if any, as of which it is expected that holders of record of Common Stock shall be entitled to receive securities or other property deliverable upon such action. Such notice shall be given in the case of any action covered by clause (i) or (ii) above at least ten days prior to the record date for determining holders of Common Stock for purposes of receiving such payment or offer, or in the case of any action covered by clause (iii) above at least 30 days prior to the date upon which such action takes place and 20 days prior to any record date to determine holders of Common Stock entitled to receive such securities or other property. 7.5 Effect of Failure to Notify. Failure to file any certificate or notice or to give any notice, or any defect in any certificate or notice pursuant to Sections 7.3 and 7.4 shall not affect the legality or validity of the adjustment to the Exercise Price, the number of shares purchasable upon exercise of this Warrant, or any transaction giving rise thereto. 8. Reports Under Securities Exchange Act of 1934. With a view to making available to the Warrantholder the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the SEC that may at any time permit the Warrantholder to sell securities of the Company to the public without registration ("Rule 144"), the Company agrees, at all times when the Warrantholder may need to rely on Rule 144 to sell such securities to the public without registration, to: (a) make and keep public information available, as those terms are understood and defined in Rule 144, at all times; (b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and (c) furnish to the Warrantholder so long as the Warrantholder owns this Warrant, promptly upon request, (i) a written statement by the Company that it has complied with the reporting 10 requirements of Rule 144 (at any time after 90 days after the effective date of the first registration statement filed by the Company), the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Warrantholder to sell such securities without registration. 9.
