In order to

5


 

exercise this Warrant, in whole or in part, the Holder shall (i) deliver to the Company at its Designated Office a written notice of the Holder’s election to exercise this Warrant (an “Exercise Notice”) substantially in the form attached to this Warrant as Annex A, which Exercise Notice shall be irrevocable and specify the number of shares of Warrant Stock to be purchased, together with this Warrant and (ii) pay to the Company the Warrant Price in accordance with Section 2.1(c) hereof. The date on which such delivery and payment shall have taken place being hereinafter sometimes referred to as the “Exercise Date.”
          (b) Upon receipt by the Company of such Exercise Notice, surrender of this Warrant and payment of the Warrant Price (in accordance with Section 2.1(c) hereof), the Company shall, as promptly as practicable, and in any event within five (5) Business Days thereafter, execute (or cause to be executed) and deliver (or cause to be delivered) to the Holder (i) a certificate or certificates representing the shares of Warrant Stock issuable upon such exercise, together with cash in lieu of any fraction of a share, as hereafter provided, and (ii) a new Warrant, if applicable, pursuant to Section 2.1(d) hereof.

This Warrant shall be deemed to have been exercised and such certificate or certificates of Warrant Stock shall be deemed to have been issued, and the Holder or any other Person so designated to be named therein shall be deemed to have become a holder of record of such shares of Warrant Stock for all purposes, as of the Exercise Date.
          (c) Payment of the Warrant Price shall be made at the option of the Holder by one or more of the following methods: (i) by delivery of a certified or official bank check or by wire transfer of immediately available funds in the amount of such Warrant Price payable to the order of the Company, (ii) by instructing the Company to withhold a number of shares of Warrant Stock then issuable upon exercise of this Warrant with an aggregate Fair Market Value equal to such Warrant Price, (iii) by surrendering to the Company shares of Common Stock previously acquired by the Holder with an aggregate Fair Market Value equal to such Warrant Price or (iv) any combination of the foregoing. In the event of any withholding of Warrant Stock or surrender of Common Stock pursuant to clause (ii), (iii) or (iv) above where the number of shares whose Fair Market Value is equal to the Warrant Price is not a whole number, the number of shares withheld by or surrendered to the Company shall be rounded up to the nearest whole share and the Company shall make a cash payment to the Holder based on the incremental fraction of a share being so withheld by or surrendered to the Company in an amount determined in accordance with Section 2.3 hereof. Notwithstanding the foregoing, the Holder will pay an amount per share of Warrant Stock equal to the par value, or such other amount as is necessary to have fully paid and nonassessable shares of the Company, provided that any such election by a Holder shall not relieve the Company of any liability or obligation it may have under this Warrant.
          (d) If this Warrant shall have been exercised in part, the Company shall, at the time of delivery of the certificate or certificates representing the shares of Warrant Stock being issued, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the

unpurchased shares of Warrant Stock called for by this Warrant. Such new Warrant shall in all other respects be identical to this Warrant.
          (e) All Warrants delivered for exercise shall be canceled by the Company.

The Company shall pay all expenses in connection with, and all taxes and other governmental charges that may be imposed with respect to, the issue or delivery thereof.
          2.3 Fractional Shares. The Company shall not be required to issue a fractional share of Warrant Stock upon exercise of any Warrant. As to any fraction of a share that the Holder of one or more Warrants, the rights under which are exercised in the same transaction, would otherwise be entitled to purchase upon such exercise, the Company shall pay to such Holder an amount in cash equal to such fraction multiplied by the Fair Market Value of one share of Common Stock on the Exercise Date.
3. TRANSFER, DIVISION AND COMBINATION
          3.1 Compliance with Securities Act. The Holder, by acceptance hereof, agrees to comply in all respects with the provisions of this Section 3.1 and further agrees that this Warrant and the Warrant Stock to be issued upon exercise hereof are being acquired for investment for its own account and that such Holder will not offer, sell or otherwise Transfer this Warrant or any Warrant Stock to be issued upon exercise hereof, in whole or in part, except under circumstances that will not result in a violation of the Securities Act.

          (b) The Holder understands that the securities it is purchasing are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Securities Act, only in certain limited circumstances. In addition, the Holder represents that it is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.
          (c) The Holder is an investor that can bear the economic risk of its investment, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Warrant and the Warrant Stock.

Subject to compliance with the applicable provisions of this Warrant, this Warrant may be divided or combined with other Warrants upon presentation hereof at the Designated Office, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney.

          (a) the Exercise Price in effect immediately prior to the issuance of such Common Stock, options, rights or securities by
          (b) a fraction of which (x) the numerator shall be the sum of (i) the number of shares of Common Stock Outstanding immediately prior to such issuance and (ii) the number of additional shares of Common Stock which the aggregate consideration for the number of shares of Common Stock so offered would purchase at the Fair Market Value per share of Common Stock and (y) the denominator shall be the number of shares of Common Stock Outstanding immediately after such issuance.

     (i) (1) the product of (a) the number of shares of Common Stock Outstanding and (b) the Fair Market Value per share of Common Stock, in each case immediately prior to such event, minus (2) the aggregate consideration paid by the Company in such event (plus, in the case of such options, rights, or convertible or exchangeable securities, the aggregate additional consideration required to be paid to the Company upon exercise, conversion or exchange), by
     (ii) the number of shares of Common Stock Outstanding immediately after such event, and
(y) the denominator shall be the Fair Market Value per share of Common Stock immediately prior to such event.

10


 

     (ii) the aggregate maximum number of shares of Common Stock that potentially may be deliverable upon conversion of or in exchange for any such convertible or exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof at any time during the term thereof shall be deemed to have been issued at the time such securities, options or rights were issued and for a consideration equal to the consideration received by the Company for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the additional consideration, if any, to be received by the Company upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in paragraph (a) above);
     (iii) on any increase in the number of shares or decrease in the effective exercise or conversion price of Common Stock deliverable upon exercise of any such options, rights or securities or conversions of or exchanges of such securities, including any change resulting from the anti-dilution provisions thereof, the Exercise Price shall forthwith be readjusted to such Exercise Price as would have been obtained had the adjustment made upon the issuance of such options, rights or securities not converted prior to such change or options or rights related to such securities not converted prior to such change been made upon the basis of such change; and
     (iv) no further adjustment of the Exercise Price adjusted upon the issuance of any such options, rights, convertible securities or exchangeable securities shall be made as a result of the actual issuance of Common Stock on the exercise of any such rights or options or any conversion or exchange of any such securities.

If, at any time after the Original Issue Date, the number of shares of Common Stock Outstanding is increased by a stock dividend payable in shares of Common Stock or by a subdivision or split-up of shares of Common Stock, then, following the record date for the determination of holders of Common Stock entitled to receive such stock dividend, or to be affected by such subdivision or split-up, the Exercise Price shall be appropriately decreased by multiplying the Exercise Price by a fraction, the numerator of which is the number of shares of Common Stock Outstanding immediately prior to such increase and the denominator of which is the number of shares of Common Stock Outstanding immediately after such increase in Outstanding shares.
          4.5 Upon Combinations or Reverse Stock Splits. If, at any time after the Original Issue Date, the number of shares of Common Stock Outstanding is decreased by a combination or reverse stock split of the Outstanding shares of Common Stock into a smaller number of shares of Common Stock, then, following the record date to determine shares affected by such combination or reverse stock split, the Exercise Price shall be appropriately increased by multiplying the Exercise Price by a fraction, the numerator of which is the number of shares of Common Stock Outstanding immediately prior to such decrease and the denominator of which is

11


 

the number of shares of Common Stock Outstanding immediately after such decrease in Outstanding shares.

In the event of any capital reorganization of the Company, any reclassification of the stock of the Company (other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), or any consolidation or merger of the Company with or into another Person (where the Company is not the surviving Person or where there is a change in or distribution with respect to the Common Stock), each Warrant shall after such reorganization, reclassification, consolidation or merger be exercisable for the kind and number of shares of stock or other securities or property of the Company or of the successor Person resulting from such consolidation or surviving such merger, if any, to which the holder of the number of shares of Common Stock deliverable (immediately prior to the time of such reorganization, reclassification, consolidation or merger) upon exercise of such Warrant would have been entitled upon such reorganization, reclassification, consolidation or merger. The provisions of this clause shall similarly apply to successive reorganizations, reclassifications, consolidations or mergers. The Company shall not effect any such reorganization, reclassification, consolidation or merger unless, prior to the consummation thereof, the successor Person (if other than the Company) resulting from such reorganization, reclassification, consolidation or merger, shall assume, by written instrument, the obligation to deliver to the Holders of the Warrant such shares of stock, securities or assets, which, in accordance with the foregoing provisions, such Holders shall be entitled to receive upon such conversion.
          4.7 Deferral in Certain Circumstances. In any case in which the provisions of this Section 4 shall require that an adjustment shall become effective immediately after a record date of an event, the Company may defer until the occurrence of such event (a) issuing to the Holder of any Warrant exercised after such record date and before the occurrence of such event the shares of capital stock issuable upon such exercise by reason of the adjustment required by such event and issuing to such Holder only the shares of capital stock issuable upon such exercise before giving effect to such adjustments, and (b) paying to such Holder any amount in cash in lieu of a fractional share of capital stock pursuant to Section 2.3 above; provided, however, that the Company shall deliver to such Holder an appropriate instrument or due bills evidencing such Holder’s right to receive such additional shares or such cash.
          4.8 Other Anti-Dilution Provisions. If the Company has issued or issues any securities of the Company to a financial institution, lender, other credit provider, leasing company or other lessor in connection with the provisions of any financing or lending agreements, containing provisions (including, without limitation, any of the terms of pricing, exercise price, anti-dilution and registration rights) which are more favorable than those set forth herein, the Company will make such provisions (or any more favorable portion thereof) available to the Holder at no cost and will enter into amendments necessary to confer such rights on the Holder.
          4.9 Voluntary Reduction. The Company from time to time may reduce the Exercise Price by any amount for any period of time if the period is at least 20 days and if the reduction is irrevocable during the period; provided, however, that in no event may the Exercise

12


 

Price be less than the par value of a share of Common Stock. Whenever the Exercise Price is reduced, the Company shall mail to all Holders a notice of the reduction. The Company shall mail the notice at least 15 days before the date the reduced Exercise Price takes effect. The notice shall state the reduced Exercise Price and the period it will be in effect.

In any case in which the provisions of this Section 4 shall necessitate that the Appraisal Procedure be utilized for purposes of determining an adjustment to the Exercise Price, the Company may defer until the completion of the Appraisal Procedure and the determination of the adjustment (1) issuing to the Holder of any Warrant exercised after the date of the event that requires the adjustment and before completion of the Appraisal Procedure and the determination of the adjustment, the shares of capital stock issuable upon such exercise by reason of the adjustment required by such event and issuing to such Holder only the shares of capital stock issuable upon such exercise before giving effect to such adjustment and (2) paying to such Holder any amount in cash in lieu of a fractional share of capital stock pursuant to Section 2.3 above; provided, however, that the Company shall deliver to such Holder an appropriate instrument or due bills evidencing such Holder’s right to receive such additional shares or such cash.
          4.11 Adjustment of Number of Shares Purchasable. Upon any adjustment of the Exercise Price as provided in Section 4.1, 4.2, 4.4, 4.5 and 4.6, the Holders of the Warrants shall thereafter be entitled to purchase upon the exercise thereof, at the Exercise Price resulting from such adjustment, the number of shares of Warrant Stock (calculated to the nearest 1/100th of a share) obtained by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of shares of Warrant Stock issuable on the exercise hereof immediately prior to such adjustment and dividing the product thereof by the Exercise Price resulting from such adjustment.
          4.12 Form of Warrants. Irrespective of any adjustments of the number of shares purchasable or of the Exercise Price, Warrants theretofore or thereafter issued may continue to express the same price and number and kind of shares as are stated in the Warrants initially issuable pursuant to this Agreement (without impacting the effects of the provisions of this Section 4).
          4.13 Changes in Securities. Notwithstanding any provision in this Section 4 to the contrary and without limitation to any other provision contained in this Section 4, in the event any securities of the Company are amended, modified or otherwise altered by operation of its terms or otherwise in any manner whatsoever (including through the anti-dilution provisions thereof) that results in (i) the reduction of the effective exercise, conversion or exchange price of such securities payable upon the exercise for, or conversion or exchange into, Common Stock or other securities exercisable for, or convertible or exchangeable into, Common Stock and/or (ii) such securities becoming exercisable for, or convertible or exchange into (A) more shares or dollar amount of such securities which are, in turn exercisable for, or convertible or exchangeable into, Common Stock, or (B) more shares of Common Stock, then such amendment, modification or other alteration shall be treated for purposes of Section 4 as if the securities which have been amended, modified or altered have been terminated and new securities have been issued with the amended or modified terms. The Company shall make all necessary adjustments (including successive adjustments if required) to the Exercise Price in

13


 

accordance with Section 4, but in no event shall the Exercise Price be greater than it was immediately prior to the application of this Section 4.13 to the amendment, modification or alteration in question.
          4.14 Exceptions. Notwithstanding anything to the contrary, Section 4 shall not apply to (i) the shares of Common Stock, or options to purchase shares of Common Stock, issuable or issued to the Company’s officers, directors, employees, consultants, or advisors pursuant to the Amended and Restated Advancis Pharmaceutical Corporation Stock Incentive Plan, or other employee stock incentive programs, or other arrangements approved by the Company Board (together, the “Stock Incentive Plans”) for the primary purpose of soliciting or retaining such parties’ services; provided, that if such shares or options are granted after the date hereof with an exercise price less than the Fair Market Value at the time of the grant, then Section 4 shall apply with respect to such shares or options, (ii) the shares of Common Stock issuable upon the exercise of such options, or (iii) the exercise of the warrants issued prior to the effective date of the Purchase Agreement and disclosed in the SEC Documents.
          4.15 Notice of Adjustment of Exercise Price. Whenever the Exercise Price is adjusted, or required to be adjusted, as herein provided:
          (a) the Company shall compute the adjusted Exercise Price in accordance with this Section 4 and shall prepare a certificate signed by the treasurer or chief financial officer of the Company setting forth the adjusted Exercise Price and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed at the Designated Office; and
          (b) a notice stating that the Exercise Price has been adjusted and setting forth the adjusted Exercise Price shall forthwith be prepared by the Company, and as soon as practicable after it is prepared, and in no event greater than three (3) Business Days after such adjustment, such notice shall be mailed by the Company at its expense to all Holders at their last addresses as they shall appear in the warrant register.
5. NO IMPAIRMENT; NO DILUTION; OTHER AGREEMENTS
          5.1 No Impairment. The Company shall not by any action, including, without limitation, amending its charter documents or through any reorganization, reclassification, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other similar action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder against impairment. Without limiting the generality of the foregoing, the Company shall take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Warrant Stock upon the exercise of this Warrant, free and clear of all Liens, and shall use its best efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant. The Company shall not take any action, enter into any transaction or suffer to exist any event, action or state of facts that would cause the Exercise Price to be adjusted below the then existing par value of

14


 

Common Stock (unless the Common Stock is changed to capital stock with no par value); provided, however, that nothing herein will prevent the operation of any other provision of this Warrant, including the anti-dilution provisions of Section 4.
          5.2 No Dilution. If any event shall occur as to which the provisions of Section 4 are not strictly applicable but the failure to make any adjustment would adversely affect the purchase rights represented by the Warrant in accordance with the essential intent and principles of such Section, then, in each such case, the Company shall appoint an investment banking firm of recognized national standing, or any other financial expert that does not (or whose directors, officers, employees, affiliates or stockholders do not) have a direct or material indirect financial interest in the Company or any of its Subsidiaries, or Affiliates, who has not been, and, at the time it is called upon to give independent financial advice to the Company, is not (and none of its directors, officers, employees, affiliates or stockholders are) a promoter, director or officer of the Company or any of its Subsidiaries, which shall give their opinion upon the adjustment, if any, on a basis consistent with the essential intent and principles established in Section 4, necessary to preserve, without dilution, the purchase rights, represented by this Warrant. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the holders of the Warrants and shall make the adjustments described therein.
          5.3 Other Agreements. The Company is not a party to or bound in any manner under, and covenants that it will not enter into at any time after the date hereof, any agreement or contract (whether written or oral) with respect to any of its securities which prevents the Company from complying in any respect with the rights granted by the Company hereunder.
6. RESERVATION AND AUTHORIZATION OF COMMON STOCK
          6.1 Reservation. The Company shall at all times reserve and keep available for issuance upon the exercise of the Warrants such number of its authorized but unissued shares of Common Stock as will be required for issuance of the Warrant Stock. All shares of Warrant Stock issuable pursuant to the terms hereof, when issued upon exercise of this Warrant with payment therefor in accordance with the terms hereof, shall be duly and validly issued and fully paid and nonassessable, not subject to preemptive rights and free and clear of all Liens. Before taking any action that would result in an adjustment in the number of shares of Warrant Stock for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction over such action. If any shares of Warrant Stock required to be reserved for issuance upon exercise of Warrants require registration or qualification with any Government Entity under any federal or state law (other than under the Securities Act or any state securities law) before such shares may be so issued, the Company will in good faith and as expeditiously as possible and at its expense endeavor to cause such shares to be duly registered.
          6.2 Corporate Action. Before taking any action that would cause an adjustment reducing the Exercise Price below the then par value (if any) of the shares of Warrant Stock deliverable upon exercise of the Warrant or that would cause the number of shares of Warrant Stock issuable upon exercise of the Warrant to exceed (when taken together with all

15


 

other Outstanding shares of Common Stock) the number of shares of Common Stock that the Company is authorized to issue, the Company will take any corporate action that, in the opinion of its counsel, is necessary in order that the Company may validly and legally issue the full number of fully paid and nonassessable shares of Warrant Stock issuable upon exercise of the Warrant at such adjusted exercise price.

          7.2 Taking of Record. In the case of all dividends or other distributions by the Company to the holders of its Common Stock with respect to which any provision hereof refers to the taking of a record of such holders, the Company will in each such case take such a record and will take such record as of the close of business on a Business Day.
          7.3 Closing of Transfer Books. The Company shall not at any time close its stock transfer books or warrant transfer books so as to result in preventing or delaying the exercise or Transfer of any Warrant.

Such Designated Office shall initially be the office of the Company at 20425 Seneca Meadows Parkway, Germantown, Maryland, 20876.

          (a) as soon as practicable, but in any event within ninety (90) days after the end of each fiscal year of the Company, an income statement and a statement of cash flows for such fiscal year and a balance sheet of the Company as of the end of such year, such year-end financial reports to be prepared in accordance with GAAP and audited and certified by independent public accountants of nationally recognized standing selected by the Company;

10. DILUTION DISTRIBUTION
          10.1 In the event that any dividends are declared or paid or any other distribution is made on or with respect to the Common Stock, the Holder of this Warrant as of the record date established by the Company Board for such dividend or distribution on the Common Stock shall be entitled to receive a distribution (the “Dilution Distribution”) in an amount (whether in the form of cash, securities or other property) equal to the amount (and in the form) of the dividend or distribution that such Holder would have received had the Warrant been exercised as of the date immediately prior to the record date for such dividend or distribution, such Dilution Distribution to be payable on the same payment date established by the Company Board for the payment of such dividend or distribution; provided, however, that if the Company declares and pays a dividend or distribution on the Common Stock consisting in whole or in part of Common Stock, then no such Dilution Distribution shall be payable in respect of the Warrant on account of the portion of such dividend or distribution on the Common Stock payable in Common Stock and in lieu thereof the adjustment in Section 4 hereof shall apply. The record date for any such Dilution Distribution shall be the record date for the applicable dividend or distribution on the Common Stock, and any such Dilution Distribution shall be payable to the Persons in whose name the Warrant is registered at the close of business on the applicable record date.
          10.2 No dividend shall be paid or declared on any share of Common Stock (other than dividends payable in Common Stock for which an adjustment was made pursuant to Section 4 hereof) unless the Dilution Distribution, payable in the same consideration and manner, is simultaneously paid or provided for, as the case may be, in respect of this Warrant in an amount determined as set forth above. For purposes hereof, the term “dividends” shall include any pro rata distribution by the Company, out of funds of the Company legally available therefor, of cash, property, securities (including, but not limited to, rights, warrants or options) or other property or assets to the holders of the Common Stock, whether or not paid out of capital, surplus or earnings other than liquidation.
          10.3 Prior to declaring any dividend or making any distribution on or with respect to shares of Common Stock, the Company shall take all prior corporate action necessary

18


 

to authorize the issuance of any securities payable as the Dilution Distribution in respect of the Warrant.

If the Company fails to make, when due, any payments provided for in this Warrant, the Company shall pay to the Holder hereof (a) interest at the Agreed Rate on any amounts due and owing to such Holder and (b) such further amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees and expenses incurred by such Holder in collecting any amounts due hereunder. The Company shall indemnify, save and hold harmless the Holder hereof and the Holders of any Warrant Stock issued upon the exercise hereof from and against any and all liability, loss, cost, damage, reasonable attorneys’ and accountants’ fees and expenses, court costs and all other out-of-pocket expenses incurred in connection with or arising from any default hereunder by the Company or the enforcement of its rights hereunder as against the Company.

          11.4 Limitation of Liability. No provision hereof, in the absence of affirmative action by the Holder to purchase shares of Warrant Stock, and no enumeration herein of the rights or privileges of the Holder hereof, shall give rise to any liability of such Holder to pay the Exercise Price for any Warrant Stock other than pursuant to an exercise of this Warrant or any liability as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company. Except as set forth herein, the Holder shall not, by virtue hereof, be entitled to any rights of a stockholder of the Company and nothing contained in this Warrant shall be construed as conferring upon the Holder the right to vote or to consent or to receive notice as a stockholder in respect of meetings of stockholders for the election of directors of the Company or any other matters or any rights whatsoever as a stockholder of the Company.
          11.5 Remedies. Each of the parties hereto acknowledges and agrees that damages will not be an adequate remedy for any material breach or violation of this Warrant if such material breach or violation would cause immediate and irreparable harm (an “Irreparable Breach”). Accordingly, in the event of a threatened or ongoing Irreparable Breach, each party hereto shall be entitled to seek equitable relief of a kind appropriate in light of the nature of the ongoing or threatened Irreparable Breach, which relief may include, without limitation, specific performance or injunctive relief; provided, however, that if the party bringing such action is unsuccessful in obtaining the relief sought, the moving party shall pay the non-moving party’s reasonable costs, including attorney’s fees, incurred in connection with defending such action. Such remedies shall not be the parties’ exclusive remedies, but shall be in addition to all other remedies provided in this Warrant.

          11.7 Amendment. This Warrant and all other Warrants may be modified or amended or the provisions hereof waived only with the written consent of the Company and the Holder. Notwithstanding the foregoing, without a Holder’s written consent no such modification, amendment or waiver shall affect adversely such Holder’s rights hereunder in a discriminatory manner inconsistent with its adverse effects on rights of other Holders hereunder (other than as reflected by the different number of shares of Warrant Stock held by such Holders). This Warrant cannot be changed, modified, discharged or terminated by oral agreement.
          11.8 Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable Law, but if any provision of this Warrant shall be prohibited by or invalid under applicable Law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Warrant.
