WHEREAS, the Company has determined to issue and deliver Series B Perpetual Warrant Certificates ("WARRANT CERTIFICATES") initially in the form of Exhibit A, representing Series B Perpetual Warrants ("WARRANTS"), to the persons and in the amounts listed on Exhibit B; WHEREAS, each Warrant represented on a Warrant Certificate entitles the holder thereof to purchase one share (as adjusted) of common stock, par value $0.01 per share ("COMMON STOCK"), of the Company for each such Warrant exercised; WHEREAS, the Company desires to provide for the form and provisions of the Warrant Certificates, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the bearers of the Warrants Certificates; and WHEREAS, all acts and things necessary to make the Warrant Certificates when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent, as provided in this agreement, the valid, binding, and legal obligations of the Company, and to authorize the execution and delivery of this Agreement, have been done and performed. NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows: ARTICLE I EXECUTION AND COUNTERSIGNATURE OF WARRANT CERTIFICATES Section 1.1. Execution and countersignature of Warrant Certificates. (a) Each Warrant Certificate, whenever issued, shall be dated August 1, 2000, shall be substantially in the form of Exhibit A and may have such legends and endorsements typed, stamped, printed, lithographed or engraved thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law or with any rule or regulation pursuant thereto or with any rule or regulation of any securities exchange on which the Warrant Certificates may be listed, or to conform to customary usage. Each Warrant Certificate shall be signed by, or bear the facsimile signature of, the President or a Vice President of the Company and shall bear a facsimile of the Company's seal. In case any officer whose facsimile signature has been placed upon any Warrant Certificate shall have ceased to hold such office before such Warrant Certificate is issued, such Warrant Certificate may be issued with the same effect as if such officer had held such office at the date of issuance. No Warrant Certificate may be exercised until it has been countersigned by the Warrant Agent as provided in Section 1.1(b). (b) The Warrant Agent shall countersign a Warrant Certificate only: (i) if the Warrant Certificate is to be issued in exchange or substitution for one or more previously countersigned Warrant Certificates, as hereinafter provided, or (ii) if the Company instructs the Warrant Agent to do so. (c) Unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant Certificate shall be invalid and of no effect. ARTICLE II WARRANT PRICE, DURATION AND EXERCISE OF WARRANT CERTIFICATES Section 2.1. Warrant Price. Each Warrant shall, when the Warrant Certificate by which such Warrant is represented is countersigned by the Warrant Agent, entitle the holder thereof, subject to the provisions thereof and of this Agreement, to purchase from the Company one share of Common Stock at the price of $4.21 per share, subject to adjustment as provided in Article III. The term "WARRANT PRICE" as used in this Agreement refers to the price per share at which Common Stock may be purchased at the time a Warrant is exercised. Section 2.2. Perpetual Duration of Warrants. The Warrants are perpetual; that is, the Warrants will not expire. Section 2.3. Exercise of Warrants. (a) A Warrant, when the Warrant Certificate by which such Warrant is represented is countersigned by the Warrant Agent, may be exercised in whole or part, at any time of from time to time, by surrendering such Warrant Certificate at the corporate trust office of the Warrant Agent in New York, with the subscription form set forth in the Warrant Certificate duly executed, and by paying in full, in lawful money of the United States, the Warrant Price for each full share of Common Stock as to which such Warrant is exercised and any applicable taxes. (b) As soon as practicable after the exercise of any Warrant, the Company shall issue to or to the order of the holder of such Warrant a certificate or certificates for the number of whole shares of Common Stock to which such holder is entitled, registered in such name or names as may be directed by such holder, and, if such Warrant shall not have been exercised in full (except with respect to a remaining fraction of a share), a new countersigned Warrant Certificate for the number of Warrants represented by such holder's previous Warrant Certificate which shall not have been exercised. In the event that the holder of one or more Warrants exercising his purchase rights thereunder has pursuant to such exercise the right to purchase a 2 fraction of a share of Common Stock, the Company shall, in lieu of issuing to such holder a fractional share, pay such holder cash in an amount equal to: (i) (x) the fraction to which such holder is entitled multiplied by (y) the closing market price of a share of Common Stock on the business day immediately following the day of exercise minus (ii) (x) the same fraction multiplied by (y) the Warrant Price on such day. If no sale takes place on such day, the closing market price for such day shall be deemed to be (i) the average of the closing bid and asked prices on such day, as officially quoted, as reported in the principal reporting system with respect to securities listed on the principal national securities exchange or market on which the Common Stock is listed or admitted to trading or, if the Common Stock is not listed or admitted to trading on any national securities exchange or market, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the- counter market, as reported by NASDAQ or such other system then in use or, if on any such date the Common Stock is not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Common Stock selected by the Board of Directors of the Company or, if on such day no such market maker is making a market in the Common Stock, the fair value of the Common Stock on such date as determined in good faith by the Board of Directors of the Company. (c) All shares of Common Stock issued upon the exercise of a Warrant shall be validly issued, and the Company shall pay all taxes in respect of the issue thereof. The Company shall not be required, however, to pay any tax imposed in connection with any transfer involved in the issue of a certificate for shares of Common Stock in any name other than that of the holder of the Warrant Certificate surrendered in connection with the purchase thereof; and in such case the Company shall not be required to issue or deliver any stock certificate until such tax shall have been paid. (d) Each person (or entity) 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 such shares on the date on which the Warrant Certificate was surrendered and payment of the Warrant Price and any applicable taxes was made, irrespective of the date of delivery of such certificate, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the Company's stock transfer books are open. (e) The Warrant Agent shall cancel any Warrant Certificate surrendered for exchange, substitution, transfer or exercise in whole or in part. ARTICLE III ADJUSTMENTS Section 3.1. Stock Dividends and Splits. If after the date hereof, and subject to the provisions of Section 3.6, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock or by a split of shares of Common Stock, then, on the date fixed for the determination of holders of Common Stock entitled to receive such 3 stock dividend or for the effectiveness of such split, the number of shares of Common Stock issuable on exercise of each Warrant shall be adjusted in proportion to such adjustment in outstanding shares and the then applicable Warrant Price shall be correspondingly adjusted. Section 3.2. Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 3.6, the number of outstanding shares of Common Stock is adjusted by a combination or reclassification (excluding any such reclassification in connection with a merger, consolidation, share exchange or similar transaction in which the Company is the continuing entity) of shares of Common Stock, then, upon the effective date of such combination or reclassification, the number of shares of Common Stock issuable on exercise of each Warrant shall be adjusted in proportion to such adjustment in outstanding shares and the then applicable Warrant Price shall be correspondingly adjusted. Section 3.3. Reorganization, Merger and Asset Sales. If after the date hereof any capital reorganization or reclassification of the Common Stock of the Company, or any consolidation, merger, share exchange or similar transaction involving the Company, or the sale of all or substantially all of the Company's assets shall be effected, then, as a condition of such reorganization, reclassification, consolidation, merger, share exchange, similar transaction or asset sale, lawful and fair provision shall be made whereby the Warrant Certificate holders shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions specified in the Warrant Certificates and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the Warrants represented thereby, such shares of stock, securities, or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such stock immediately theretofore purchasable and receivable upon the exercise of the Warrants had such reorganization, reclassification, consolidation, merger, share exchange, similar transaction or asset sale not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of the Warrant Certificate holders to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Warrant Price and of the number of shares purchasable upon the exercise of the Warrants) shall thereafter be applicable, as nearly as may be in relation to any share of stock, securities, or assets thereafter deliverable upon the exercise hereof. The Company shall not effect any such consolidation, merger, share exchange, similar transaction or sale unless prior to the consummation thereof the successor entity (if other than the Company) resulting from such transaction, or the entity purchasing such assets, shall assume by written instrument executed and delivered to the Warrant Agent the obligation to deliver to the Warrant Certificate holders such shares of stock, securities, or assets as, in accordance with the foregoing provisions, such holders may be entitled to purchase. Section 3.4. Notice of Changes in Warrants. Upon any adjustment of the Warrant Price or the number of shares issuable on exercise of a Warrant, then and in each such case the Company shall promptly give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from any such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. 4 The Company shall also mail such notice to the addresses of the Warrant Certificate holders reflected in the records of the Warrant Agent. Failure to give or publish such notice, or any defect therein, shall not affect the legality or validity of the subject adjustments. Section 3.5. Other Notices. If at any time: (a) the Company shall pay any dividends payable in stock upon its Common Stock or make any distribution (other than regular cash dividends) to the holders of its Common Stock; (b) the Company shall offer for subscription pro rata to the holders of its Common Stock any additional shares of stock of any class or other rights; (c) there shall be any capital reorganization, or reclassification of the capital stock of the Company, or consolidation, merger, share exchange or similar transaction of the Company with, or sale of all or substantially all of the Company's assets to, another entity; and (d) there shall be a voluntary or involuntary dissolution, liquidation, or winding up of the Company; then, in any one or more of such cases, the Company shall give written notice and publish the same in the manner set forth in Section 3.4, of the date on which (i) the books of the Company shall close or a record shall be taken for such dividend, distribution, or subscription rights, or (ii) such transaction shall take place, as the case may be. Such notice shall also specify the date as of which the holders of record of Common Stock shall participate in such dividend, distribution, or subscription rights, or shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation, or winding up, as the case may be. Such notice shall be given and published at least 20 days prior to the action in question and not less than 20 days prior to the record date or the date on which the Company's transfer books are closed in respect thereto. Failure to give or publish such notice, or any defect therein, shall not affect the legality or validity of any of the matters set forth in the foregoing clauses (a) to (d), both inclusive. Section 3.6. Limitation on Fractions. Notwithstanding anything to the contrary in Section 3.1 or 3.2, upon exercise of any Warrant, cumulative adjustments in the number of shares issuable upon exercise of Warrants shall be made only to the nearest multiple of one-tenth of a share, i.e., fractions of less than five-hundredths of a share shall be disregarded and fractions of five- hundredths of a share or more shall be treated as being one-tenth of a share. Section 3.7. Form of Warrant Certificate. The form of Warrant Certificate need not be changed because of any change pursuant to this Article III, and Warrant Certificates issued after such change may state the same Warrant Price and the same number of shares as is stated in the Warrant Certificates initially issued pursuant to this Agreement. The Company may at any time in its sole discretion (which shall be conclusive) make any change in the form of Warrant Certificate that the Company may deem appropriate and that does not affect the substance thereof; and any Warrant Certificate thereafter issued or countersigned, whether in exchange or 5 substitution for an outstanding Warrant Certificate or otherwise, may be in the form as so changed. ARTICLE IV OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF WARRANT CERTIFICATES Section 4.1. No Rights as Shareholder Conferred by Warrant Certificates. No Warrant Certificate holder, as such, shall be entitled to vote or to receive dividends or shall otherwise be deemed to be the holder of shares of Common Stock for any purpose, nor shall anything contained herein or in any Warrant Certificate be construed to confer upon any Warrant Certificate holder, as such, any of the rights of a stockholder of the Company or any right to vote upon or withhold consent to any action of the Company (whether upon any reorganization, issuance of securities, reclassification or conversion of Common Stock, consolidation, merger, share exchange or similar transaction, sale, lease, conveyance or otherwise), receive notice of meetings or other action affecting stockholders (except for notices expressly provided for in this Agreement) or receive dividends or subscription rights. Section 4.2. Lost, Stolen, Mutilated, or Destroyed Warrant Certificates.

Any such new Warrant Certificate shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant Certificate shall be at any time enforceable by anyone. Section 4.3. Reservation of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants.
