Such Purchaser is acquiring the Securities to be purchased by such Purchaser under this Agreement solely for his own beneficial account, for investment purposes, and not with any view to, or for resale in connection with, any distribution of any such Securities. Such Purchaser understands that the Securities have not been registered under the Securities Act of 1933, as amended (the "Act"), or any state securities laws, by reason of specific exemptions under the provisions thereof which depend in part upon the investment intent of such Purchaser and upon the accuracy of the other representations made by such Purchaser in this Agreement.

Such Purchaser is a director of the Company and an "accredited investor" as defined in Regulation D pursuant to the Act. 4. Restrictive Legends. 4.1. Each certificate or other document representing any of the Securities issued pursuant to this Agreement shall be stamped or otherwise imprinted with a restrictive legend in the form set forth on the form of the Warrant attached hereto as an exhibit (or, in the case of shares of Series E Preferred Stock or shares of common stock issuable upon conversion thereof or exercise of the Warrants, an equivalent legend appropriately modified to refer to such Securities). In the event of any transfer or reissuance of any such Security, the certificates or other instruments representing such Securities shall continue to bear such legends. 4.2. The Company hereby agrees that it will promptly deliver or cause to be delivered a new certificate or certificates or instrument or instruments for any Securities, which certificate or certificates or instrument or instruments will not bear the legends referred to above, upon determination by the Company that such Securities have been held beneficially by the holder for at least three years and that such holder is not and has not been within the preceding three months an affiliate of the Company. All determinations pursuant to the preceding sentence shall be made in accordance with Rule 144(k) under the Act or any applicable successor rule. In the event that a period shorter than specified above is permitted by reason of the amendment or replacement of such Rule 144(k), then the Company shall impose no greater restriction than the restriction imposed as the result of such amendment or replacement. 5. Conditions to the Obligations of the Purchasers. The obligations of each Purchaser to purchase the Securities to be purchased by such Purchaser under this Agreement are subject to the satisfaction or waiver by such Purchaser of the following conditions: 5.1.

The representations of each Purchaser set forth in Section 3 of this Agreement shall be true and correct in all material respects at the time of such purchase and sale of such Securities; and 6.3. The Company shall have received such consents, waivers and agreements from its secured bank lender as shall be required, in the judgment of the Company, to permit the issuance and sale of such Securities with the result that, upon consummation of such issuance and sale, the Company shall not be in default (or shall be subject to a forbearance agreement reasonably satisfactory to the Company with respect to any such default) under the provisions of any agreement or instrument governing or evidencing any obligations of the Company to its secured bank lender. 7. Registration Rights. 7.1. As used in this Section 7: (a) The terms "register," "registered" and "registration" refer to a registration effective by preparing and filing a registration statement in compliance with the Act, and the declaration or ordering of the effectiveness of such registration statement. (b) The term "Registrable Securities" means: (i) any common stock of the Company ("Common Stock") issued, or issuable, upon the conversion of any Series E Preferred Stock regardless of whether such conversion has taken place at any time; (ii) any Common Stock issued, or issuable upon the conversion or exercise of any Warrant, regardless of whether such exercise has taken place at any time, or any warrant, right or other security which is issued as a dividend or other distribution with respect to, or in exchange for or in replacement of, any Series E Preferred Stock or any Warrant; and (iii) any Common Stock issued as a dividend on any Series E Preferred Stock; excluding in all cases, however, any Registrable Securities sold by a person in a transaction in which his rights under this Section 7 are not assigned. (c) The term "Holder" means any holder of Registrable Securities who acquired such Registrable Securities in a transaction or series of transactions not involving any public offering or any sale pursuant to Rule 144 under the Act. 7.2. The Company hereby agrees that: (a) If at any time or from time to time, the Company determines to register any of its securities, either for its own account or the account of a security holder or holders, (other than a registration solely to implement an employee benefit plan or a registration on Form S-4 or a Rights Offering as such term is defined in the Certificate of Designation), the Company will: (i) promptly give to each Holder written notice thereof (which will include a list of the jurisdictions in which the Company intends to attempt to qualify such securities under the applicable blue sky law or other state securities laws); and (ii) include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in any written request or requests by any Holder received by the Company within twenty days after such written notice is given and make its best efforts to qualify all the Registrable Securities specified in such request under the blue sky or other securities laws of any jurisdiction which said Holders may reasonably request. (b) If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company will so advise the Holders as a part of the written notice given pursuant to Section 7.2(a)(i) above. In such event, the right of any Holder to registration pursuant to this Section 7.2 will be conditioned upon such Holder's participation in such underwriting and the inclusion of such Holder's Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute Registrable Securities through such underwriting (together with the Company and the other shareholders distributing their securities through such underwriting) will enter into an underwriting agreement in customary form, satisfactory to the Company, with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of this Section 7.2, if the managing underwriter determines in good faith that marketing factors require a limitation of the number of shares to be underwritten for the accounts of Holders of Registrable Securities and other securities of the Company entitled to registration pursuant to agreements with the Company, the managing underwriter may limit the number of Registrable Securities and other securities of the Company entitled to registration pursuant to agreements with the Company to be included in the registration. The Company will so advise all Holders of Registrable Securities and all shareholders owning securities of the Company entitled to registration pursuant to agreements with the Company and participating in such registration, and the number of shares of Registrable Securities and such other securities that may be included in the registration and underwriting will be allocated among all Holders and other shareholders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities and such other securities entitled to such registration held by such Holders and other shareholders at the time of filing the registration statement. No Registrable Securities excluded from the underwriting by reason of the underwriter's marketing limitation will be included in such registration. If any Holder disapproves of the terms of the underwriting, he may elect to withdraw therefrom by written notice to the Company and the managing underwriter. The Registrable Securities so withdrawn will also be withdrawn from registration; provided, however, that, if by the withdrawal of such Registrable Securities or any other securities entitled to registration pursuant to agreements with the Company a greater number of Registrable Securities held by Holders may be included in such registration (up to the maximum of any limitation imposed by the managing underwriter) then the Company will offer to all Holders and other shareholders who have included Registrable Securities and such other securities in the registration the right to include additional Registrable Securities or other securities in portion to the amounts of their Registrable Securities and such other securities so included. (c) The Company shall cooperate and communicate with all Holders wishing to participate in any registration pursuant to this Section 7.2 so as to permit them a reasonable and effective opportunity to participate, including providing prompt notice of any stop orders and copies of all registration statements and prospectuses filed with the Securities and Exchange Commission, including any amendments, and any such other materials and information that is provided to other participating securities holders. The Company will bear all expenses of any registration, including filing fees, blue sky fees and expenses, accounting and legal fees and expenses, printing and mailing costs and other similar expenses, but will not bear any expenses (including fees of legal counsel) incurred by participating Holders and will not bear any underwriting discount or concession or similar sale costs with respect to Registrable Securities offered and sold by or for participating Holders. The Company and the participating Holders will agree to indemnify each other or to contribute to one another on reasonable and customary terms. 8. Selection of Shares to be Redeemed or Converted. If less than all the Series E Preferred Stock is required to be redeemed or converted pursuant to Subsections 5(a) or 6(a) of the Certificate of Designation, the shares to be redeemed or converted shall be determined by written agreement of the Purchasers or, if the Purchasers fail to tender a written agreement to the Company prior to the time for redemption or conversion, the shares to be redeemed or converted shall be determined as follows: 8.1. The first 100,000 shares of Series E Preferred Stock redeemed pursuant to Subsection 5(a) of the Certificate of Designation shall be redeemed from those shares purchased by Barker and any remaining shares redeemed shall be redeemed ratably from the balance of the Series E Preferred Stock purchased by each Purchaser after deducting therefrom any Series E Preferred Stock tendered by the Purchaser to pay for Common Stock purchased in a Rights Offering pursuant to Subsection 5(b) of the Certificate of Designation. 8.2. Any Series E Preferred Stock converted pursuant to Subsection 6(a) of the Certification of Designation shall come ratably from the Series E Preferred Stock purchased by each Purchaser after deducting therefrom any Series E Preferred Stock tendered by the Purchaser to pay for Common Stock purchased in a Rights Offering pursuant to Subsection 5(b) of the Certificate of Designation. 8.3. Should either or both Purchasers transfer all or any part of their Series E Preferred Stock, the shares transferred shall be treated for purposes of the computations in this Section 8 as still owned by the transferring Purchaser and a pro rata portion of any shares required to be redeemed or converted from the shares originally purchased by the Purchaser shall be converted or redeemed from those transferred. The Purchasers shall notify each transferee of the restrictions in this Agreement and shall require that each transferee notify any transferee from it of such restrictions. 9. Miscellaneous. 9.1. Remedies Not Exclusive. No remedy conferred by any of the specific provisions of this Agreement is intended to be exclusive of any other remedy, and each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now or hereafter existing at law or in equity or by statute or otherwise. The election of any one or more remedies by any party hereto shall not constitute a waiver of the right to pursue other available remedies. 9.2. Parties Bound. Except to the extent otherwise expressly provided herein, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, representatives, administrators, guardians, successors and assigns; and no other person shall have any right, benefit or obligation hereunder. 9.3.

Notice shall be deemed given on the date of delivery, in the case of personal delivery or telecopy, or on the delivery or refusal date, as specified on the return receipt, in the case of overnight courier or registered or certified mail. 9.4. Choice of Law. This Agreement shall be construed, interpreted, and the rights of the parties determined in accordance with, the laws of the State of Delaware, without giving effect to any conflicts of laws principles. 9.5. Entire Agreement; Amendments and Waivers; Assignment. This Agreement, together with all exhibits and schedules hereto, constitutes the entire agreement between the parties pertaining to the subject matter hereof and supersedes all prior and contemporaneous agreements, understandings, negotiations and discussions, whether oral or written, of the parties. Except as set forth herein, there are no warranties, representations or other agreements between the parties in connection with the subject matter hereof. No supplement, modification or waiver of this Agreement shall be binding unless it shall be specifically designated to be a supplement, modification or wavier of this Agreement and shall be executed in writing by each party to be bound thereby. No wavier of any of the provisions of this Agreement shall be binding unless executed in writing by the party to be bound thereby. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided. In the event of any permitted transfer of any Securities, any rights of the holder thereof pursuant to Section 7 shall be transferred automatically. Except as set forth in the preceding sentence and except as provided in Section 8 hereof, this Agreement may not be assigned by operation of law or otherwise. 9.6. Further Assurances.

Multiple Counterparts. This Agreement may be executed in or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 9.8.

Designation. The series shall be designated as the "Series E Redeemable Convertible Preferred Stock" (the "Series E Preferred Stock"). 2. Number. The number of shares of the Series E Preferred Stock authorized to be issued is 300,000. 3. Dividends. (a) The Corporation shall pay to the holders of the Series E Preferred Stock, a mandatory quarterly dividend at an annual rate of 11.25% of the Stated Amount (as such term is defined in Section 4 below) payable solely in the form of Common Stock of the Corporation, subject only to the Corporation being able to lawfully pay such dividend in accordance with applicable law. Dividends on the Series E Preferred Stock shall commence to accrue and are cumulative (whether or not declared) from the date on which such shares shall have been issued until the date on which such shares are redeemed, converted or exchanged. Such dividends shall be mandatorily payable as stated above, in Common Stock of the Corporation at its Current Market Price (as defined below) on the date of payment, in equal quarterly payments in arrears on the last day of each fiscal quarter of the Corporation of each year or such earlier date on which a share of Series E Preferred Stock is redeemed, converted or exchanged (each such date being referred to herein as a "Dividend Payment Date"), commencing December 31, 1996, or if not paid on such Dividend Payment Date by reason of a prohibition against such payment pursuant to the first sentence of this Subsection (a) (a "Payment Prohibition"), then promptly when and to the extent no such Payment Prohibition continues to apply; provided, however, that the dividend payable in respect of the quarter ended on the first dividend payment date after the date on which such shares shall have been issued and in respect of any other quarter in which some or all of the Series E Preferred Stock was not outstanding for the entire quarter shall be reduced in proportion to the portion of such quarterly period in which such shares were not outstanding; and provided further, however, that if and to the extent that, at any dividend payment date, the Corporation shall fail to make any quarterly dividend payment on the Series E Preferred Stock (which failure shall only be permitted to the extent a Payment Prohibition applies), such unpaid dividend amount shall accumulate without interest until paid. Such dividends shall be paid to the Series E Preferred Stock stockholders of record on the last business day immediately preceding the date of payment. All partial dividends paid with respect to shares of the Series E Preferred Stock shall be paid pro rata to the holders entitled thereto in proportion to the total amount of dividends to which each is entitled. The "Current Market Price" of the Corporation's Common Stock on any given day shall be: (i) if the Common Stock is listed or admitted to unlisted trading privileges on any exchange registered with the Securities and Exchange Commission as a "national securities exchange" under the Securities Exchange Act of 1934 (a "National Securities Exchange"), the arithmetic average of the last sales price of the shares of Common Stock on the National Securities Exchange in or nearest the City of New York on which the shares of Common Stock shall be listed or admitted to unlisted trading privileges (or the quoted closing bid if there be no sales on such National Securities Exchange) on the ten most recently completed trading days prior to such day; or (ii) if the Common Stock is not so listed or admitted, the arithmetic average of the closing sales price of a share of Common Stock as quoted in The Nasdaq Stock Market on the ten most recently completed trading days prior to the day in question; or (iii) if the Common Stock is not so quoted, the arithmetic average of the mean between the high and low bid prices of a share of Common Stock in the over-the-counter market on the ten most recently completed trading days prior to the day in question as reported by National Quotation Bureau Incorporated or a similar organization. (b) So long as any shares of the Series E Preferred Stock are outstanding, unless all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series E Preferred Stock outstanding shall have been paid in full, the Corporation shall not: (i) pay or declare any dividends, or make any other distributions, on any shares of stock ranking junior to the Series E Preferred Stock in respect of dividends or distribution of assets upon any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary (a "Liquidation"); (ii) pay or declare any dividends, or make any other distributions, on any shares of stock ranking on a parity to the Series E Preferred Stock in respect of dividends or distribution of assets upon Liquidation, except dividends paid ratably on the Series E Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled; or (iii) redeem or purchase or otherwise acquire for consideration shares of any stock ranking junior to the Series E Preferred Stock in respect of dividends or distribution of assets upon Liquidation, provided that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such junior stock in exchange for shares of any stock of the Corporation raking junior to the Series E Preferred Stock in respect of dividends or distribution of assets upon Liquidation. Except as otherwise provided in this Subsection (b), the Board of Directors may declare and the Corporation may pay or set apart for payment dividends and other distributions on the common stock (the "Common Stock") and the preferred stock (the "Preferred Stock") of the Corporation ranking junior to or on a parity with the Series E Preferred Stock in respect of dividends or distributions of assets upon Liquidation, and may redeem, purchase, retire or otherwise acquire for consideration shares of Common Stock or Preferred Stock ranking junior to or on a parity with the Series E Preferred Stock in respect of dividends or distributions of assets upon Liquidation, and the holders of the Series E Preferred Stock shall not be entitled to share therein. (c) In the event the Corporation, not being in violation of the provisions of the preceding paragraph, shall distribute to all holders of its Common Stock (x) evidences of indebtedness or assets and property other than cash, (y) capital stock of the Corporation other than Common Stock, or (z) rights to purchase only (i) Common Stock (except in a Rights Offering as defined in Subsection 5(b) below) or (ii) units consisting of shares of Common Stock and warrants to purchase shares of Common Stock (all of such distributions collectively hereinafter called "Shared Distributions"), then the holders of the Series E Preferred Stock shall participate in such Shared Distributions as if immediately prior to the record date for determination of stockholders entitled to receive such Shared Distribution such holders had converted their shares of the Series E Preferred Stock in to shares of Common Stock. 4. Liquidation Rights. In the event of the Liquidation of the Corporation, the holders of the Series E Preferred Stock shall be entitled to have paid to them out of the assets of the Corporation, before any distribution is made to or set apart for the holders of Common Stock or of any other class or series of stock of the Corporation ranking junior to the Series E Preferred Stock in respect of distribution of assets upon Liquidation, an amount equal to $10. 00 per share (the " Stated Amount"), plus unpaid dividends and Shared Distributions which have accrued but have not been paid on or prior to the date of final distribution to holders of the Series E Preferred Stock, and no more. The liquidation payment with respect to each outstanding fractional share of the Series E Preferred Stock shall be equal to a ratably proportionate amount of the liquidation payment with respect to each outstanding share of the Series E Preferred Stock. If upon any Liquidation of the Corporation the assets of the Corporation or proceeds thereof distributable among the holders of shares of the Series E Preferred Stock and the holders of any stock on a parity with the Series E Preferred Stock shall be insufficient to pay in full the preferential amounts payable to such holders, then such assets or the proceeds thereof shall be distributed among such holders ratably in accordance with the respective amounts that would be payable on such shares if all amounts payable thereon were paid in full. For purposes of this Section 4, the voluntary sale, lease, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property or assets of the Corporation to, or a consolidation or merger of the Corporation with, one or more corporations shall not be deemed to be a Liquidation. 5. Redemption. (a) Shares of the Series E Preferred Stock shall be redeemed by the Corporation on the first business day (the "Redemption Date") following the issuance of Common Stock in a Rights Offering (as defined in Subsection 5(b) below) from the proceeds of such Rights Offering at the Stated Amount of such Series E Preferred Stock (in addition to the payment in Common Stock pursuant to Subsection 1 (a) above of dividends to the Redemption Date on the Series E Preferred Stock redeemed) to the extent that the purchase price of the Common Stock sold in the Rights Offering plus the Stated Amount of the Series E Preferred outstanding on the Redemption Date is in excess of $5,000,000. If less than all of the Series E Preferred Stock outstanding is redeemed, the Series E Preferred Stock to be redeemed shall be determined pursuant to the agreement for the initial purchase of the Series E Preferred Stock. Except as provided in the Subsection 5(a), the Series E Preferred Stock shall not be subject to redemption. Any Series E Preferred Stock called for redemption pursuant to this Subsection 5(a) but not tendered by the holder thereof for redemption shall be deemed cancelled and shall no longer be treated as outstanding and no dividends or Shared Distributions thereon or interest on the redemption price shall be paid in regard to the period on or after the Redemption Date. (b) The term "Rights Offering" shall refer to any offering of rights to acquire the Corporation's Common Stock made after October 31, 1996 and prior to June 30, 1997. The Corporation shall not make a Rights Offering without the consent of all the holders of the Series E Preferred Stock except on the terms set forth in this Subsection 5(b). Any Rights Offering shall be an offer, to all holders of record of the Corporation's Common Stock on or about the second business day preceding the date the registration of the Rights Offering is declared effective by the Securities and Exchange Commission, to purchase one share of Common Stock for each share of Common Stock held of record on such date at a purchase price of $1.00 per share payable, within 30 days after the effective date of such Rights Offering, either in cash or by tender of Series E Preferred Stock for exchange for such Common Stock at the Stated Amount of such Series E Preferred Stock. Any Series E Preferred Stock tendered in payment of the purchase price of Common Stock in the Rights Offering at its Stated Amount shall be cancelled but dividends in Common Stock shall be paid thereon pursuant to Section l(a) to the date of exchange. Nothing herein or in any other document shall obligate the Corporation to make any Rights Offering. Other than pursuant to a Rights Offering or to options, warrants, or other rights outstanding prior to November 1, 1996, the Corporation shall not issue any shares of Common Stock in addition to these outstanding on October 3 1, 1996 prior to July 1, 1997. 6. Conversion Rights. (a) If there is a Rights Offering and less than 5,000,000 shares of Common Stock are sold pursuant to the Rights Offering, one share of Series E Preferred Stock shall be converted into 10 shares of fully paid and nonassessable Common Stock for each 10 shares or portion thereof of Common Stock less than 5,000,000 sold in the Rights Offering. Such conversion shall occur on the first business day (the "Mandatory Conversion Date") immediately following the expiration of the Rights Offering. If less than all of the Series E Preferred Stock is required to be converted, the Series E Preferred Stock to be converted shall be determined pursuant to the agreement for the initial purchase of the Series E Preferred Stock. Any Series E Preferred Stock required to be converted pursuant to this Subsection 6(a) but not tendered for conversion shall be deemed cancelled on the Mandatory Conversion Date and shall no longer be treated as outstanding. Dividends accrued to the Mandatory Conversion Date shall be paid pursuant to Subsection l(a) on the Series E Preferred Stock converted but no dividends or Shared Distributions thereon shall be paid in regard to the period on and after the Mandatory Conversion Date. For all purposes the holders of record of the Series E Preferred Stock required to be converted on the Mandatory Conversion Date shall be deemed to have become the record holder or holders of the Common Stock in to which such Series E Preferred Stock is convertible on the Mandatory Conversion Date. (b) Subject to the provisions for adjustment hereinafter set forth, shares of Series E Preferred Stock may be converted, at the option of the holder thereof, at any time or from time to time after June 30, 1997 into fully paid and nonassessable whole shares of Common Stock at rate of 10 shares of Common Stock for each share of the Series D Preferred Stock duly surrendered for conversion. Dividends accrued to the Date of Conversion (as defined below), shall be paid pursuant to Subsection 1(a) on the Series E Preferred Stock converted but no dividends or Shared Distributions with respect to the shares of Series D Preferred Stock converted shall be paid in regard to the period on and after the Date of Conversion. (c) Each holder of the Series E Preferred Stock desiring to exercise such holder's right of conversion pursuant to Subsection 6(b) shall deliver written notice of election to convert, stating the names and addresses of the persons to whom the Common Stock is to be issued, and shall surrender the certificate or certificates for the shares of Series E Preferred Stock to be converted, duly endorsed or accompanied by proper instruments of transfer (unless such endorsement or instruments are waived by the Corporation) to the Corporation during usual business hours at the office of the transfer agent of the Corporation for the transfer of its Common Stock in Dallas, Texas (or such other place as may be designated by the Corporation upon written notice to all holders of the Series E Preferred Stock). Upon receipt by the Corporation of any such notice of election to convert shares of the Series E Preferred Stock, and upon surrender of the certificate or certificates therefor, the Corporation shall execute and deliver, as soon as practicable, to the converting holder, or to such holder's nominee or nominees, a certificate or certificates for the number of shares of Common Stock resulting from such conversion, together with any cash adjustment in lieu of fractional shares as provided in Subsection (e). For all purposes, the rights of a converting holder, as such, shall cease, and the person or persons in whose name or names the certificate or certificates for Common Stock issuable upon such conversion are to be issued shall be deemed to have become the record holder or holders of such Common Stock at the close of business on the day (the "Date of Conversion") on which delivery of such notice or the surrender of the certificate or certificates for such shares (whichever shall later occur) shall be made. (d) The Corporation shall pay all issue costs, if any, incurred in respect to the Common Stock delivered on conversion; provided, however, that the Corporation shall not be required to pay transfer or other taxes, if any, incurred by reason of the issuance or delivery of such Common Stock in names other than those in which the shares surrendered for conversion are registered, and no delivery of certificates for such Common Stock shall be made unless and until there has been paid to the Corporation the amount of any such taxes, or there shall have been established to the satisfaction of the Corporation that such taxes have been or are not required to be paid. The Corporation shall not close its books against the transfer of Series E Preferred Stock or of Common Stock issued or issuable upon conversion of Series E Preferred Stock in any manner which interferes with the timely conversion of Series E Preferred Stock. The Corporation shall assist and cooperate with any holder of shares of Series E Preferred Stock required to make any required governmental filings or obtain any governmental approval prior to or in connection with any conversion of such shares hereunder (including, without limitation, making any filings required to be made by the Corporation). All shares of Common Stock which are so issuable shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. The Corporation shall take all such actions as may be necessary to assure that all such shares of Common Stock may be so issued without violation of any applicable law or governmental regulation or any requirements of any domestic securities exchange upon which shares of Common Stock may be listed (except for official notice of issuance which shall be immediately delivered by the Corporation upon each such issuance). (e) The Corporation shall not be required to issue fractional shares of Common Stock upon conversion of shares of the Series E Preferred Stock. If more than one share of the Series E Preferred Stock shall be surrendered for conversion at one time by the same holder, the number of full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares so surrendered. If any fractional interest in a share of Common Stock would be deliverable upon the conversion of any shares, the Corporation shall, in lieu of delivering such fractional share, make a cash payment, as an adjustment in respect of such undelivered fraction of a share, in an amount equal to the same fraction of the Current Market Price of one share of the Common Stock on the last business day before the Date of Conversion. (f) The number of shares of Common Stock into which each share of the Series E Preferred Stock is convertible (the "Conversion Rate") shall be subject to adjustment from time to time as follows: (i) In case the Corporation shall (A) pay a dividend in or make a distribution of Common Stock on outstanding Common Stock, (B) subdivide outstanding Common Stock into a larger number of shares of Common Stock by reclassification or otherwise, or (C) combine outstanding Common Stock into a smaller number of shares of Common Stock by reclassification or otherwise, the Conversion Rate in effect immediately prior thereto shall be adjusted proportionately so that the holder of a share of the Series E Preferred Stock thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock that such holder would have owned after the happening of any of the events described above had such share been converted immediately prior to the happening of such event. An adjustment made pursuant to this subparagraph (i) shall become effective retroactively to immediately after the record date in the case of a share dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination. (ii) In case of any capital reorganization or reclassification of the shares of Common Stock (except as provided in subparagraph (i) above), or in case of any consolidation or merger to which the Corporation is a party (other than a merger in which the Corporation is the surviving corporation and which does not result in any capital reorganization or reclassification of Common Stock), or in case of any sale or conveyance to another corporation of all or substantially all of the property and assets of the Corporation, and if, in connection with any such consolidation, merger, sale or conveyance, shares or other securities or property shall be issuable or deliverable in exchange for shares of Common Stock, provision shall be made as part of the terms of such capital reorganization or reclassification, consolidation, merger, sale or conveyance that the holder of each share of the Series E Preferred Stock thereafter surrendered for conversion shall have the right to convert such share into the same kind and amount of stock and other securities and property as would have been receivable upon such capital reorganization or reclassification, consolidation, merger, sale or conveyance by a holder of the number of shares of Common Stock into which such share might have been converted immediately prior thereto. In any such case, appropriate provision (as determined to be equitable in the business judgment of the Board of Directors) shall be made for the application of Section 6 with respect to the rights and interest thereafter of the holders of the Series E Preferred Stock to the end that such Section (including adjustments of the Conversion Rate) shall be reflected thereafter, as nearly as reasonably practicable, in all subsequent conversions of the Series E Preferred Stock. The Corporation shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor corporation (if other than the Corporation) resulting from consolidation or merger or the corporation purchasing such assets assumes by written instrument (in a manner determined to be equitable in the business judgment of the Board of Directors to the holders of the Series E Preferred Stock then outstanding), the obligation to deliver to each such holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such holder may be entitled to acquire. (iii) In case the Corporation shall issue, other than pursuant to a Rights Offering, pro rata to the holders of shares of its Common Stock rights or warrants entitling them, during a period not exceeding 30 days after the record date mentioned below, to subscribe for or purchase only shares of its Common Stock at a price per share less than the average of the Current Market Price (as defined above) of the Common Stock determined as of such record date, the number of shares of its Common Stock into which each share of the Series E Preferred Stock shall be convertible thereafter shall be determined by multiplying the number of shares of Common Stock into which each such share was convertible theretofore by a fraction, of which the numerator shall be the number of shares of Common Stock outstanding immediately prior to such record date plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the denominator shall be the number of shares of Common Stock outstanding immediately prior to such record date plus the number of shares of Common Stock which the aggregate offering price of the total number of shares being offered would purchase at such Current Market Price. Such adjustment shall be made whenever such rights or warrants are issued and shall become retroactively effective immediately after the record date for the determination of the stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made upon the basis of delivery of only the number of shares of Common Stock actually delivered. (iv) In case the Corporation shall issue, other than pursuant to a Rights Offering, pro rata to the holders of shares of its Common Stock rights or warrants to subscribe for or purchase only (A) shares of its Common Stock except as described in subparagraph (iii) above, or (B) units consisting of shares of Common Stock and warrants to purchase shares of Common Stock, the number of shares of its Common Stock into which each share of the Series E Preferred Stock shall be convertible thereafter shall be determined by multiplying the number of shares of Common Stock into which each such share was convertible theretofore by a fraction, of which the numerator shall be the Current Market Price for a share of Common Stock determined as of the record date mentioned below, and of which the denominator shall be such Current Market Price less the fair market value (as determined in the business judgment of the Board of Directors) as of such record date of the rights or warrants distributed pro rata to one of the outstanding shares of Common Stock. Such adjustment shall be made whenever such distribution is made and shall become retroactively effective immediately after the record date for the determination of stockholders entitled to receive such rights or warrants. (v) In case the Corporation shall issue or sell any shares (including treasury shares) of Common Stock ("Additional Shares of Common Stock"), whether or not subsequently reacquired or retired by the Corporation, other than shares of Common Stock issued (A) upon exercise of warrants to purchase shares of Common Stock issued prior to or substantially simultaneously with the first issuance of shares of the Series E Preferred Stock, (B) pursuant to any stock option plan or other stock incentive or stock ownership plan for employees or management of the Corporation, (C) pursuant to a Rights Offering, or (D) in payment of dividends on the Series E Preferred Stock, for a cash purchase price per share that is less than the quotient of $10.00 divided by the number of shares of Common Stock into which each share of Series E Preferred Stock was theretofore convertible (such quotient, the "Conversion Price"), the number of shares of Common Stock into which each share of the Series E Preferred Stock shall be convertible thereafter shall be determined by multiplying the number of shares of Common Stock into which each such share was convertible theretofore by a fraction, of which the numerator shall be the number of shares of Common Stock outstanding immediately after such issuance or sale, and of which the denominator shall be the number of shares of Common Stock outstanding immediately prior to such issuance or sale plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for such Additional Shares of Common Stock so issued or sold would purchase at the Conversion Price. Such adjustment shall be made whenever any such Additional Shares of Common Stock are so issued or sold. The foregoing provisions for adjustment of the Conversion Rate shall apply in each successive instance in which an adjustment is required thereby. No adjustment in the Conversion Rate resulting from the application of the foregoing provisions is to be given effect unless, by making such adjustment, the Conversion Rate in effect immediately prior to such adjustment would be changed thereby by 1% or more, but any adjustment that would change the Conversion Rate by less than 1% is to be carried forward and given effect in making future adjustments; provided, however, that each adjustment of the conversion Rate shall in all events be made not later than three years from the date such adjustment would have been required to be made except for the provisions of this sentence. All calculations under this Section 6 shall be made to the nearest one-hundredth (1/100th) of a share. Shares of Common Stock owned by or held for the account of the Corporation shall not be deemed to be outstanding for the purposes of any computation made under this Section 6. Whenever the number of shares of Common Stock deliverable upon the conversion of shares of the Series E Preferred Stock shall be adjusted pursuant to the provisions hereof, the Corporation shall forthwith file at its principal office and with any transfer agent for the Series E Preferred Stock and for the Common Stock a statement, signed by the President or one of the Vice-Presidents of the Corporation and by its Treasurer or one of its Assistant Treasurers, stating the adjusted number of shares of Common Stock deliverable per share of the Series E Preferred Stock and setting forth in reasonable detail, the method of calculation and the facts requiring such adjustment and upon which such calculation is based, and shall mail a notice of such adjustment to each holder of record of the Series E Preferred Stock. Each adjustment shall remain in effect until a subsequent adjustment hereunder is required. In the event: (x) of the occurrence of any of the events referred to in subparagraphs (i), (ii), (iii) and (iv) above; or (y) of the Liquidation of the Corporation; then the Corporation shall cause to be mailed to any transfer agent for the Series E Preferred Stock and to the holders of record of the outstanding shares of the Series E Preferred Stock at least 20 days prior to the applicable date hereinafter specified, a notice describing the event and stating the effect, if any, that such event will have upon the Conversion Rate, and (A) the date on which a record is to be taken for the purpose of a distribution referred to in subparagraphs (i), (iii) or (iv) above, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such distribution are to be determined, or (B) the date on which any subdivision, combination or other capital reorganization or reclassification or any consolidation, merger, sale or conveyance referred to in subparagraphs (i) or (ii) above or such Liquidation is expected to become effective. The Corporation will at all times reserve and keep available for issuance upon conversion of the Series E Preferred Stock the number of shares of Common Stock that is equal to the number of shares of the Series E Preferred Stock outstanding multiplied by the Conversion Rate; provided, however, that nothing contained herein shall be construed to preclude the Corporation from satisfying its obligations in respect of the conversion of the outstanding shares of the Series E Preferred Stock by delivery of shares of Common Stock that are held in the treasury of the Corporation. The Corporation covenants that all shares of Common Stock that shall be issued upon conversion of the shares of the Series E Preferred Stock will, upon issue, be fully paid and nonassessable and not subject to any preemptive rights. The shares of Common Stock issuable upon conversion of the shares of the Series E Preferred Stock when the same shall be issued in accordance with the terms of the Series E Preferred Stock are hereby declared to be and shall be fully paid nonassessable shares of Common Stock and not liable to any calls or assessments thereon, and the holders thereof shall not be liable for any further payments in respect thereof. "Common Stock" when used in Section 6 with reference to the Common Stock into which the Series E Preferred Stock is convertible and when used in Section 8 below, shall mean only Common Stock as authorized by the Restated Certificate of Incorporation of the Corporation, as amended to the date hereof, and any shares into which such Common Stock may thereafter have been changed, and, when otherwise used in Section 6 and when used in Section 3, shall also include shares of the Corporation of any other class or series, whether now or hereafter authorized, that ranks or is entitled to participation, as to payment of assets upon Liquidation and payment of dividends, substantially on a parity with such Common Stock or other class of shares into which such Common Stock may have been changed. The Corporation will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, 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 in 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 privilege of the holders of the Series E Preferred Stock against dilution or other impairment. Without limiting the generality of the foregoing, the Corporation (1) will not increase the par value of any shares of stock receivable upon conversion of the Series E Preferred Stock above the Conversion Price then in effect, and (2) will take all such actions as may be necessary or appropriate in order that the Corporation may validly and legally issue fully paid and nonassessable shares of stock upon the conversion in full of all Series E Preferred Stock from time to time outstanding. 7. Voting Rights. Except as otherwise required by applicable law, the holders of the Series E Preferred Stock shall have no voting rights or powers. 8. Ranking. The Series E Preferred Stock shall rank senior to the Common Stock (as defined in Section 6) and to all other series of the Corporation's preferred stock as to the payment of dividends and Shared Distributions, and as to the distribution of the Corporation's assets, unless the terms and designations of any such series of preferred stock shall provide otherwise, provided, however, that in no event shall the Series E Preferred Stock rank junior to any other class or series of the Corporation's capital stock. 9. Other Rights. The holders of the Series E Preferred Stock shall not have any other preferences or special rights. 10. Registration of Transfer. The Corporation shall keep at its principal office a register for the registration of Series E Preferred Stock. Upon the surrender of any certificate representing Series E Preferred Stock at such place, the Corporation shall, at the request of the record holder of such certificate, execute and deliver (at the Corporation's expense) a new certificate or certificates in exchange therefor representing in the aggregate the number of shares of Series E Preferred Stock represented by the surrendered certificate. Each such new certificate shall be registered in such name (upon satisfactory compliance with all applicable securities laws) and shall represent such number of Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Series E Preferred Stock represented by such new certificate from the date to which dividends have been fully paid on such Series E Preferred Stock represented by the surrendered certificate. 11. Replacement. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing shares of any class of Series E Preferred Stock, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that the holder's own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such class represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on the Series E Preferred Stock represented by such new certificate from the date to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate. 12. Amendment and Waiver. Any amendment, modification or waiver shall be binding or effective with respect to any provision of Sections 1 to 12 hereof with the prior written consent of all the holders of the Series E Preferred Stock outstanding at the time such action is taken. IN WITNESS WHEREOF, the undersigned officers of the Corporation have executed and subscribed this Certificate this _____ day of November, 1996. AMERICAN ECOLOGY CORPORATION By: --- Name: ----- Title: ------ ATTEST: ----------------------------------------- Name: ----- Title: ------ Number: W --------- NEITHER THIS WARRANT NOR ANY SHARES OF COMMON STOCK ISSUABLE UPON THE EXERCISE HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR ANY OTHER SECURITIES STATUTE. NO SALE, TRANSFER OR OTHER DISPOSITION HEREOF OR THEREOF, OR OF ANY INTEREST HEREIN OR THEREIN, MAY BE MADE OR SHALL BE RECOGNIZED UNLESS IN THE OPINION OF COUNSEL TO OR REASONABLY SATISFACTORY TO THE COMPANY SUCH TRANSACTION WOULD NOT VIOLATE OR REQUIRE REGISTRATION UNDER SUCH ACT OR OTHER STATUTE. WARRANT TO PURCHASE COMMON STOCK OF AMERICAN ECOLOGY CORPORATION THIS WARRANT CERTIFIES that, for value received, ___________________, (the "Holder") is entitled to purchase from American Ecology Corporation, a Delaware corporation (the "Company"), at a price of $1.50 per share, subject to adjustment as provided in Section 4 hereof ("Purchase Price"), at any time after June 30, 1997 up to and including June 30, 2003 (such period, the "Exercise Period"), _________________ fully paid and non-assessable shares of the Company's Common Stock, par value $.Ol per share ("Common Stock"), subject, however, to the provisions and upon the terms and conditions hereinafter set forth. 1. Exercise of Warrant. The rights represented by this Warrant may be exercised by the holder hereof, at any time or from time to time during the Exercise Period, on any day that is not a Saturday, Sunday or public holiday under the laws of the State of Idaho (such day being hereinafter referred to as a "Business Day"), for all or part of the number of shares of Common Stock purchasable upon its exercise, by (i) delivery of a Subscription Notice (in the form attached to this Warrant) of such holder's election to exercise this Warrant, specifying the number of shares of Common Stock to be purchased, (ii) payment of the Purchase Price for such shares by certified check or bank draft payable to the order of the Company and (iii) surrender of this Warrant (properly endorsed if required) at the Company's principal office or such other office or agency of the Company as the Company may designate by notice in writing to the holder hereof. In the event of any exercise of the rights represented by this Warrant, certificates for the shares of Common Stock so purchased shall be delivered to the holder hereof as soon as reasonably practicable, but in any event within twenty-one days, after the rights represented by this Warrant shall have been so exercised, and unless this Warrant has expired, a new Warrant representing the number of shares of Common Stock, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the holder hereof within such time. Each person in whose name any such certificate for shares of Common Stock is issued shall for all purposes be deemed to have become the holder of record of the Common Stock represented hereby on the date on which this Warrant was surrendered and payment of the Purchase Price was made, irrespective of the date of issue or delivery of such certificate. 2. Transfer. The Company will maintain books for the registration and transfer of the Warrants, and any such transfer will be registrable thereon upon surrender of the transferred Warrant to the Company's main office, together with a duly executed assignment thereof and funds sufficient to pay any required stock transfer taxes. Upon such surrender and payment, the Company shall, subject to Section 9, execute and deliver a new Warrant or Warrants in the name of the assignees and in the number of shares of Common Stock specified in the assignment and this Warrant shall promptly be cancelled. 3. Certain Covenants of the Company. The Company covenants and agrees that all shares of Common Stock that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and non-assessable and free from all taxes, liens, charges and security interests with respect to the issue thereof. The Company further covenants and agrees that during the period within which the rights represented by the Warrant may be exercised, the Company will at all times have authorized, and reserved free of preemptive or other rights for the exclusive purpose of issue upon exercise of the rights evidenced by this Warrant, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant. The Company shall take all such actions as may be necessary to assure that all such shares of Common Stock may be issued upon the exercise of the rights represented by this Warrant without violation of any applicable law or governmental regulation or any requirements of any domestic securities exchange upon which shares of Common Stock may be listed (except for official notice of issuance which shall be immediately delivered by the Company upon each such issuance). 4. Adjustment of Purchase Price and Number of Shares. The number of shares of Common Stock with respect to which this Warrant is exercisable (the "Exercise Rate") shall be subject to adjustment from time to time as follows: a. In case the Company shall (x) pay a dividend in or make a distribution of Common Stock on outstanding Common Stock, (y) subdivide outstanding Common Stock into a larger number of shares of Common Stock by reclassification or otherwise, or (z) combine outstanding Common Stock into a smaller number of shares of Common Stock by reclassification or otherwise, the Exercise Rate in effect immediately prior thereto shall be adjusted proportionately so that the holder of this Warrant thereafter exercised shall be entitled to receive the number of shares of the Common Stock that such holder would have owned after the happening of any of the events described above had such warrant been exercised immediately prior to the happening of such event. An adjustment made pursuant to this subparagraph (a) shall become effective retroactively to immediately after the record date in the case of a share dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination. b. In case of any capital reorganization or reclassification of the shares of Common Stock (except as provided in subparagraph (a) above), or in case of any consolidation or merger to which the Company is a party (other than a merger in which the Company is the surviving corporation and which does not result in any capital reorganization or reclassification of Common Stock), or in case of any sale or conveyance to another corporation of all or substantially all of the property and assets of the Company, and if, in connection with any such consolidation, merger, sale or conveyance, shares or other securities or property shall be issuable or deliverable in exchange for shares of Common Stock, provision shall be made as part of the terms of such capital reorganization or reclassification, consolidation, merger, sale or conveyance that the holder of this Warrant thereafter exercised shall have the right upon such exercise to receive the same kind and amount of stock and other securities and property as would have been receivable upon such capital reorganization or reclassification, consolidation, merger, sale or conveyance by a holder of the number shares of Common Stock with respect to which such Warrant might have been exercised immediately prior thereto. In any such case, appropriate provision (as determined to be equitable in the business judgment of the Board of Directors) shall be made for the application of Section 4 with respect to the rights and interests thereafter of the holder of this Warrant to the end that such Section (including adjustments of the Exercised Rate) shall be reflected thereafter, as nearly as reasonably practicable, in all subsequent exercises of this Warrant. The Company shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor corporation (if other than the Company) resulting from consolidation or merger or the corporation purchasing such assets assumes by written instrument (in a manner determined to be equitable in the business judgment of the Board of Directors to the holder of this Warrant), the obligation to deliver to such holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such holder may be entitled to acquire. c. In case the Company shall issue (other than pursuant to a Rights Offering as defined in the Company's Certificate of Designation, Preferences and Rights of Series E Redeemable Convertible Preferred Stock) pro rata to the holders of shares of its Common Stock rights or warrants entitling them, during a period not exceeding 30 days after the record date mentioned below, to subscribe for or purchase only shares of its Common Stock at a price per share less than the average of the Current Market Price (as defined in Section 6) of the Common Stock for the 30 consecutive trading days commencing 45 days before such record date (the "Average Market Price"), the number of shares of its Common Stock with respect to which this Warrant is exercisable thereafter shall be determined by multiplying the number of shares of Common Stock with respect to which this Warrant was exercisable theretofore by a fraction, of which the numerator shall be the number of shares of Common Stock outstanding immediately prior to such record date plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the denominator shall be the number of shares of Common Stock outstanding immediately prior to such record date plus the number of shares of Common Stock which the aggregate offering pr ice of the total number of shares being offered would purchase at such Average Market Price. Such adjustment shall be made whenever such rights or warrants are issued and shall become retroactively effective immediately after the record date for the determination of the stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such rights or warrants, the Exercise Rate shall be readjusted to the Exercise Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made upon the basis of delivery of only the number of shares of Common Stock actually delivered. d. In case the Company shall issue (except pursuant to a Rights Offering as defined in subparagraph (c) above) pro rata to the holders of shares of its Common Stock rights or warrants to subscribe for or purchase only (x) shares of its Common Stock except as described in subparagraph (c) above, or (y) units consisting of shares of Common Stock and warrants to purchase shares of Common Stock, the number of shares of its Common Stock with respect to which this Warrant is exercisable thereafter shall be determined by multiplying the number of shares of Common Stock with respect to which this Warrant was exercisable theretofore by a fraction, of which the numerator shall be the Average Market Price for a share of Common Stock determined as of the record date mentioned below, and of which the denominator shall be such Average Market Price less the fair market value (as determined in the business judgment of the Board of Directors) as of such record date of the rights or warrants distributed pro rata to one of the outstanding shares of Common Stock. Such adjustment shall be made whenever such distribution is made and shall become retroactively effective immediately after the record date for the determination of stockholders entitled to receive such rights or warrants. The foregoing provisions for adjustment of the Exercise Rate shall apply in each successive instance in which an adjustment is required thereby. No adjustment in the Exercise Rate resulting from the application of the foregoing provisions is to be given effect unless, by making such adjustment, the Exercise Rate in effect immediately prior to such adjustment would be changed thereby by 1% or more, but any adjustment that would change the Exercise Rate by less than 1% is to be carried forward and given effect in making future adjustments; provided, however, that each adjustment of the Exercise Rate shall in all events be made no later than three years from the date such adjustment would have been required to be made except for the provisions of this sentence. All calculations under this Section 4 shall be made to the nearest one-hundredth (1/100th) of a share. Shares of Common Stock owned by or held for the account of the Company shall not be deemed to be outstanding for the purposes of any computation made under this Section 4. Whenever the number of shares of Common Stock deliverable upon the exercise of this Warrant shall be adjusted pursuant to the provisions hereof, the Company shall forthwith file at its principal office and with any transfer agent for the Common Stock a statement, signed by the President or one of the Vice-Presidents of the Company and by its Treasurer or one of its Assistant Treasurers, stating the adjusted number of shares of Common Stock deliverable with respect to this Warrant and setting forth in reasonable detail the method of calculation and the facts requiring such adjustment and upon which such calculation is based, and shall mail a notice of such adjustment to the holder of record of this Warrant. Each adjustment shall remain in effect until a subsequent adjustment hereunder is required. In the event: (x) of the occurrence of any of the events referred to in subparagraphs (a), (b), (c) and (d) above; or (y) of any liquidation, dissolution or winding up of the Company (a "Liquidation"); then the Company shall cause to be mailed to the holder of record of this Warrant at least 20 days prior to the applicable date hereinafter specified, a notice describing the event and stating the effect, if any, that such event will have upon the Exercise Rate, and (A) the date on which a record is to be taken for the purpose of a distribution referred to in subparagraphs (a), (c) or (d) above, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such distribution are to be determined, or (B) the date on which any subdivision, combination or other capital reorganization or reclassification or any consolidation, merger, sale or conveyance referred to in subparagraphs (a) or (b) above or such Liquidation is expected to become effective. The Company will at all times during the Exercise Period reserve and keep available for issuance upon exercise of this Warrant the number of shares of Common Stock that is equal to the Exercise Rate; provided, however, that nothing contained herein shall be construed to preclude the Company from satisfying its obligations in respect of the exercise of this Warrant by delivery of shares of Common Stock that are held in the treasury of the Company. The Company covenants that all shares of Common Stock that shall be issued upon exercise of this Warrant will, upon issue, be fully paid and nonassessable and not subject to any preemptive rights. The shares of Common Stock issuable upon exercise of this Warrant when the same shall be issued in accordance with the terms hereof are hereby declared to be and shall be fully paid nonassessable shares of Common Stock and not liable to any calls or assessments thereon, and the holders thereof shall not be liable for any further payments in respect thereof. "Common Stock" when used in Section 4 with reference to the Common Stock with respect to which this Warrant is exercisable, shall mean only Common Stock as authorized by the Restated Certificate of Incorporation of the Company, as amended to the date hereof, and any shares into which such Common Stock may thereafter have been changed, and, when otherwise used in Section 4, shall also include shares of the Company of any other class or series, whether now or hereafter authorized, that ranks or is entitled to participation, as to payment of assets upon Liquidation and payment of dividends, substantially on a parity with such Common Stock or other class of shares into which such Common Stock may have been changed. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the company, but will at all times in good faith assist in the carrying out of all the provisions of this Section 4 and in the taking of all such action as may be necessary or appropriate in order to protect the conversion privilege of the holders of this Warrant against dilution or other impairment. Without limiting the generality of the foregoing, the Company (1) will not increase the par value of any shares of stock receivable upon exercise of this Warrant above the Purchase Price then in effect, and (2) will take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of stock upon the exercise in full of this Warrant from time to time outstanding. 5. Fractional Interests. The Company shall not be required to issue fractional shares on the exercise of a Warrant. If any faction of a share would be issuable on the exercise of a Warrant (or specified portion thereof), the Company shall pay an amount in cash equal to the Current Market Price per share of Common Stock (as defined in Section 6) multiplied by such fraction. 6. Definition of Current Market Value. The "Current Market Price" on any given day shall be: (i) if the Common Stock is listed or admitted to unlisted trading privileges on any exchange registered with the Securities and Exchange Commission as a national securities exchange" under the Securities Exchange Act of 1934 (a "National Securities Exchange"), the last sales price of the shares of Common Stock on the National Securities Exchange in or nearest the City of New York on which the shares of Common Stock shall be listed or admitted to unlisted trading privileges (or the quoted closing bid if there be no sales on such National Securities Exchange) on the most recently completed trading day prior to such day; or (ii) if the Common Stock is not so listed or admitted, the closing sales price of a share of Common Stock as quoted in The Nasdaq Stock Market on the most recently completed trading day prior to the day in question; or (iii) if the Common Stock is not so quoted, the mean between the high and low bid prices of the shares of Common Stock in the over-the-counter market on the most recently completed trading day prior to the day in question as reported by National Quotation Bureau Incorporated or similar organization. 7. Taking of Record; Stock and Warrant Transfer Books. 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 of Section 4 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. The Company will not at any time, except upon dissolution, liquidation or winding up of the Company, close its stock transfer books or Warrant transfer books so as to result in preventing or delaying the exercise or transfer of any Warrant. 8.
