CLASS A COMMON STOCK PURCHASE WARRANT (Void after December 20, 1999) Cryenco Sciences, Inc. (the "Company"), for value received, hereby certifies that International Capital Partners, Inc., or his, her or its registered assigns (the "Holder"), is entitled, subject to the terms set forth below, to purchase from the Company, at any time or from time to time on or after April 20, 1995 and on or before December 20, 1999 (the "Exercise Period") at not later than 5:00 p.m. (New York City time), 116,000 shares of Class A Common Stock, $0.01 par value per share, of the Company ("Common Stock") (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such Common Stock), at a purchase price per share of $4.00. The number of shares purchasable upon exercise of this Warrant, and the purchase price per share, each as adjusted from time to time pursuant to the provisions of this Warrant, are hereinafter referred to as the "Warrant Stock" and the "Purchase Price," respectively. 1. EXERCISE. (a) The purchase right represented by this Warrant may be exercised by the Holder hereof, in whole or in part, by the surrender of this Warrant (with the purchase form attached hereto as EXHIBIT 1 duly executed) at the principal office of the Company and by the payment to the Company, by certified or official bank check drawn on a major money market bank with offices in New York City or wire transfer, of an amount equal to the then applicable Purchase Price multiplied by the number of shares then being purchased. The Company agrees that the shares so purchased shall be deemed to be issued to the Holder hereof as the record owner of such shares as of the close of business on 2 the date on which this Warrant shall have been surrendered and payment made for such shares as aforesaid. In the event of any exercise of this Warrant, certificates for the shares of stock so purchased shall be delivered to the Holder hereof within 15 days thereafter and, unless this Warrant has been fully exercised or expired, a new warrant representing the portion of the shares, if any, with respect to which this Warrant shall not then have been exercised, shall also be issued to the Holder hereof within such 15 day period. (b) CONVERSION. The Holder may convert this Warrant (the "Conversion Right"), in whole or in part, into the number of shares of Common Stock of the Company calculated pursuant to the following formula by surrendering this Warrant at the principal office of the Company (together with a demand for conversion in the form attached hereto as EXHIBIT 2 duly executed) ("Conversion Demand") specifying the number of shares of Common Stock of the Company, the rights to purchase which the Holder desires to convert: Y (A-B) ------- X= A where: X = the number of shares of Common Stock to be issued to the Holder Y = the number of shares of Common Stock subject to this Warrant for which the Conversion Right is being exercised; A = the fair market value of one share of Common Stock; B = the Purchase Price As used herein, the fair market value of a share of Common Stock shall mean with respect to each share of Common Stock the closing price per share of the Company's Common Stock on the principal national securities exchange on which the Common Stock is then listed or admitted to trading or, if not then listed or admitted to trading on any such exchange, on the NASDAQ National Market System, or if not then listed or traded on any such exchange or system, the bid price per share on the NASDAQ Small-Cap Market, averaged over the 10 trading days consisting of the day as of which the current fair market value of Common Stock is being determined (which day shall be the date two (2) days prior to which the Conversion Demand is, as applicable, delivered by hand, telecopied, placed in the mails or delivered to a private courier) and the nine consecutive business days prior to such day. If at any time such quotations are not available, the current fair market value of a share of Common Stock shall be the 2 3 highest price per share which the Company could obtain from a willing buyer (not a current employee or director) for shares of Common Stock sold by the Company, from authorized but unissued shares, as determined in good faith by the Board of Directors of the Company, unless the Company shall become subject to a merger, acquisition or other consolidation pursuant to which the Company is not the surviving party, in which case the current fair market value of a share of Common Stock shall be deemed to be the value received by the holders of the Company's Common Stock for each share of Common Stock pursuant to the Company's acquisition. The Company agrees that the shares so converted shall be deemed to be issued to the Holder hereof as the record owner of such shares as of the close of business on the date on which this Warrant shall have been surrendered as aforesaid. In the event of any conversion of this Warrant, certificates for the shares of stock so converted shall be delivered to the Holder hereof within 15 days thereafter and, unless this Warrant has been fully converted or expired, a new Warrant representing the portion of the shares, if any, with respect to which this Warrant shall not then have been converted, shall also be issued to the Holder hereof within such 15 day period. Exercise of the foregoing Conversion Rights shall be deemed an exercise of this Warrant for all purposes hereunder. Any adjustments in the Purchase Price or number or type of securities or other property which the Holder is entitled to receive upon exercise of this Warrant shall also apply MUTATIS MUTANDIS to the Conversion Rights provided for herein. 2. ANTI-DILUTION PROVISIONS. (a) ADJUSTMENT FOR RECAPITALIZATION. If outstanding shares of the Company's Common Stock shall be subdivided into a greater number of shares or a dividend in Common Stock shall be paid in respect of Common Stock, the Purchase Price in effect immediately prior to such subdivision or at the record date of such dividend shall simultaneously with the effectiveness of such subdivision or immediately after the record date of such dividend be proportionately reduced. If outstanding shares of Common Stock shall be combined into a smaller number of shares, the Purchase Price in effect immediately prior to such combination shall, simultaneously with the effectiveness of such combination, be proportionately increased. When any adjustment is required to be made in the Purchase Price, the number of shares of Warrant Stock purchasable upon the exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Purchase Price in effect immediately prior to such adjustment, by (ii) the Purchase Price in effect immediately after such adjustment. 3 4 (b) ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC. If there shall occur any capital reorganization or reclassification of the Company's Common Stock (other than a change in par value or a subdivision or combination as provided for in subsection 2(a) above), or any consolidation or merger of the Company with or into another corporation, or a transfer of all or substantially all of the assets of the Company, then, as part of any such reorganization, reclassification, consolidation, merger or sale, as the case may be, lawful provision shall be made so that the Holder of this Warrant shall have the right thereafter to receive upon the exercise hereof the kind and amount of shares of stock or other securities or property which such Holder would have been entitled to receive if, immediately prior to any such reorganization, reclassification, consolidation, merger or sale, as the case may be, such Holder had held the number of shares of Common Stock which were then purchasable upon the exercise of this Warrant. In any such case, appropriate adjustment (as reasonably determined by the Board of Directors of the Company) shall be made in the application of the provisions set forth herein with respect to the rights and interests thereafter of the Holder of this Warrant such that the provisions set forth in this Section 2 (including provisions with respect to adjustment of the Purchase Price) shall thereafter be applicable, as nearly as is reasonably practicable, in relation to any shares of stock or other securities or property thereafter deliverable upon the exercise of this Warrant. (c) ADJUSTMENTS FOR SALE OF SHARES OF COMMON STOCK BELOW PURCHASE PRICE. (i) SPECIAL DEFINITIONS. For purposes of this Subsection 2(c), the following definitions shall apply: (A) "OPTION" shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire Common Stock or Convertible Securities (collectively, "Rights"), excluding (1) Rights granted by the Company prior to the Original Issue Date; (2) up to 20,000 shares of Class A Common Stock issued upon exercise of options, if any, granted after the Original Issue Date under the Company's 1986 Non-Qualified Stock Option Plan and up to 79,000 shares of Class A Common Stock issued upon exercise of options, if any, granted after the Original Issue Date under the Company's 1992 Employee Incentive and Non-Qualified Stock Option Plan and up to 36,000 shares of Class A Common Stock issued upon exercise of options, if any, granted after the Original Issue Date under the Company's 1993 Non-Employee Director Stock Option Program; (3) up to an aggregate of 65,000,000 shares of Class A Common Stock issued upon exercise of warrants to purchase such 4 5 Common Stock, if any, issued, whether before or after the Original Issue Date, to one or more of Alfred Schechter, Don M. Harwell and Mezzanine Capital Corporation Limited and warrants to purchase up to an aggregate of 25,000 shares of Class A Common Stock, if any, issued to The Edgehill Corporation on or about the Original Issue Date; and (4) Rights to acquire up to 272,267 additional shares of Class A Common Stock. (B) "ORIGINAL ISSUE DATE" shall mean December 20, 1994. (C) "CONVERTIBLE SECURITIES" shall mean any evidences of indebtedness, shares or other securities directly or indirectly convertible into or exchangeable for Common Stock. (D) "ADDITIONAL SHARES OF COMMON STOCK" shall mean all shares of Common Stock issued (or, pursuant to Subsection 2(c)(iii) below, deemed to be issued) by the Company after the Original Issue Date, other than shares of Common Stock issued or issuable: (1) by reason of a dividend, stock split, split-up or other distribution on shares of Common Stock issued (or pursuant to Subsection 2(c)(iii) below deemed to be issued) by the Company after the Original Issue Date; or (2) pursuant to or upon the exercise of Rights excluded from the definition of "Option" in Subsection 2(c) (i)(A). (E) "WARRANT HOLDERS" shall mean the Holder of this Warrant and the holders of all other Warrants, from time to time, issued in connection with the sale of the Shares and Warrants pursuant to that certain Purchase Agreement dated November 29, 1994 by and among the Company, International Capital Partners, Inc. and the Purchasers defined therein, as amended (the "Purchase Agreement") and executed and delivered simultaneously with this Warrant, for so long as such holders shall hold the Warrants issued pursuant to the Purchase Agreement. (ii) NO ADJUSTMENT OF PURCHASE PRICE. No adjustment in the number of shares of Common Stock into which the Warrant is exercisable shall be made by adjustment in the applicable Purchase Price thereof; (a) unless the consideration per share (determined 5 6 pursuant to Subsection 2(c)(v) for an Additional Share of Common Stock issued or deemed to be issued by the Company is less than the applicable Purchase Price in effect on the date of, and immediately prior to, the issue of such Additional Shares of Common Stock, or (b) if prior to such issuance, the Company receives written notice from the holders of at least a majority of the then Warrant Holders agreeing that no such adjustment shall be made as the result of the issuance of Additional Shares of Common Stock. (iii) ISSUE OF SECURITIES DEEMED ISSUE OF ADDITIONAL SHARES OF COMMON STOCK. (A) If the Company at any time or from time to time after the Original Issue Date shall issue any Options or Convertible Securities or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of shares of Common Stock (as set forth if the instrument relating thereto without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date, provided that Additional Shares of Common Stock shall not be deemed to have been issued unless the consideration per share (determined pursuant to Subsection 2(c)(v) hereof) of such Additional Shares of Common Stock would be less than the applicable Purchase Price in effect on the date of and immediately prior to such issue, or such record date, as the case may be. (B) No further adjustment in the Purchase Price shall be made upon the subsequent issue of Convertible Securities or shares of Common Stock upon the exercise of such Options or conversion or exchange of such Convertible Securities. (C) If such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any increase in the consideration payable to the Company, or decrease in the number of shares of Common Stock issuable, upon the exercise, conversion or exchange thereof, the Purchase Price computed upon the original issue thereof (or upon 6 7 the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective, be recomputed to reflect such increase or decrease insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities. (D) No readjustment pursuant to clause (C) above shall have the effect of increasing the Purchase Price to an amount which exceeds the lower of (1) the Purchase Price on the original adjustment date, or (2) the Purchase Price that resulted from any other issuance of Additional Shares of Common Stock between the original adjustment date and such readjustment date. (E) Upon the expiration or termination of any unexercised Option, the Purchase Price shall be readjusted as if the expired or terminated Options had never been issued, and the Additional Shares of Common Stock deemed issued as the result of the original issue of such Option shall not be deemed issued for the purposes of any subsequent adjustment of the Purchase Price. (F) In the event of any change in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any Option or Convertible Security, including, but not limited to, a change resulting from the anti-dilution provisions thereof, the Purchase Price then in effect shall forthwith be readjusted to such Purchase Price as would have been obtained had the adjustment which was made upon the issuance of such Option or Convertible Security not exercised or converted prior to such change been made upon the basis of such change but no further adjustment shall be made for the actual issuance of Common Stock upon the exercise or conversion of any such Option or Convertible Security. (iv) ADJUSTMENT OF PURCHASE PRICE UPON ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK. In the event the Company shall at any time after the Original Issue Date issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Subsection 2(c)(iii), but excluding shares issued upon a stock split or combination or as a dividend or distribution as provided in Subsection 2(a)) without consideration or for a consideration per share less than the applicable Purchase Price in effect 7 8 on the date of and immediately prior to such issue, then, and in such event, such Purchase Price shall be reduced, concurrently with such issue, to a price (calculated to the nearest cent) determined by multiplying such Purchase Price by a fraction, (A) the numerator of which shall be (1) the number of shares of Common Stock outstanding immediately prior to such issue plus (2) the number of shares of Common Stock which the aggregate consideration received by the Company for the total number of Additional Shares of Common Stock so issued would purchase at such Purchase Price; and (B) the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of such Additional Shares of Common Stock so issued; PROVIDED THAT, for the purpose of this Subsection 2(c)(iv), all shares of Common Stock issuable upon exercise of the Warrants outstanding immediately prior to such issue shall be deemed to be outstanding, and immediately after any Additional Shares of Common Stock are deemed issued pursuant to Subsection 2(c)(iii) (other than shares excluded from the definition of "Additional Shares of Common Stock"), such Additional Shares of Common Stock shall be deemed to be outstanding. Notwithstanding the foregoing, the applicable Purchase Price shall not be so reduced at such time if the amount of such reduction would be an amount less than $.01, but any such amount shall be carried forward and reduction with respect thereto made at the time of and together with any subsequent reduction which, together with such amount and any other amount of amounts so carried forward, shall aggregate $.01 or more. (v) DETERMINATION OF CONSIDERATION. For purposes of this Subsection 2(c), the consideration received by the Company for the issue of any Additional Shares of Common Stock shall be computed as follows: (A) CASH AND PROPERTY: Such consideration shall: (1) insofar as it consists of cash, be computed at the aggregate of cash received by the Company, excluding amounts paid or payable for accrued interest or accrued dividends; (2) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as 8 9 determined in good faith by the Board of Directors; and (3) in the event Additional Shares of Common Stock are issued together with other shares or securities or other assets of the Company for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (1) and (2) above, as determined in good faith by the Board of Directors. (B) OPTIONS AND CONVERTIBLE SECURITIES. The consideration per share received by the Company for Additional Shares of Common Stock deemed to have been issued pursuant to Subsection 2(c)(iii) relating to Options and Convertible Securities shall be determined by dividing (x) the total amount, if any, received or receivable by the Company as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Company upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Common Stock, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by (y) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities. (d) CERTIFICATES AS TO ADJUSTMENTS. When any adjustment is required to be made in the Purchase Price, the Company at its expense shall promptly compute such adjustment in accordance with the terms of the Warrant and prepare a certificate executed by two officers of the Company setting forth such adjustment and showing in detail the facts upon which such adjustment is based. The Company shall forthwith mail to each Holder a copy of such certificate. Such certificate shall also set forth the kind and amount of stock or other securities or property into which this Warrant shall be exercisable following the occurrence of any of the events specified in this Section 2. 3. FRACTIONAL SHARES. The Company shall not be required upon the exercise of this Warrant to issue any 9 10 fractional shares. In lieu of delivering such fractional interest, the Company shall pay an amount to the Holder equal to the fair market value of such fractional interest as of the date of exercise. 4. LIMITATION ON SALES, ETC. Each Holder of this Warrant acknowledges that this Warrant and the Warrant Stock have not been registered under the Securities Act of 1933, as amended (the "Act"), and agrees not to sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this Warrant or any Warrant Stock issued upon its exercise in the absence of (a) an effective registration statement under the Act as to this Warrant or such Warrant Stock, or (b) an applicable exemption from such registration under such Act. Each certificate or other instrument for Warrant Stock issued upon the exercise of this Warrant shall bear a legend substantially to the foregoing effect. Notwithstanding the foregoing, the Holder may require the Company to issue a certificate representing the Warrant Stock without a legend in substitution for a legended certificate representing the Warrant Stock if either (i) such Warrant Stock has been registered for resale under the Act or (ii) such registration is no longer required under applicable law. 5. NO IMPAIRMENT. The Company will not, by amendment of its Certificate of Incorporation or through reorganization, consolidation, merger, dissolution, sale of assets or any other voluntary 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 action as may be necessary or appropriate in order to protect the rights of the Holder of this Warrant against impairment. 6. LIQUIDATING DIVIDENDS. If the Company pays a dividend or makes a distribution on the Common Stock payable otherwise than in cash out of earnings or earned surplus (determined in accordance with generally accepted accounting principles) except for a stock dividend payable in shares of Common Stock (a "Liquidating Dividend"), then the Company will pay or distribute to the Holder of this Warrant, upon the exercise hereof, in addition to the Warrant Stock purchased upon such exercise, the Liquidating Dividend which would have been paid to such Holder if he, she or it had been the owner of record of such shares of Warrant Stock immediately prior to the date on which a record is taken for such Liquidating Dividend or, if no record is taken, the date as of which the record holders of Common Stock entitled to such dividends or distribution are to be determined. 10 11 7. NOTICES OF RECORD DATE, ETC. In case: (a) The Company shall choose a date on which a record is to be taken of the holders of its Common Stock (or other stock or securities at the time deliverable upon the exercise of this Warrant) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right, or (b) of any capital reorganization of the Company, any reclassification of the capital stock of the Company, any consolidation or merger of the Company with or into another corporation (other than a consolidation or merger in which the Company is the surviving entity), or any transfer of all or substantially all of the assets of the Company, or (c) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company, then, and in each such case, the Company will mail or cause to be mailed to the Holder of this Warrant a notice specifying, as the case may be, (i) the date on which a record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, or (ii) the effective date on which such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up is to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock (or such other stock or securities at the time deliverable upon the exercise of this Warrant) shall be entitled to exchange their shares of Common Stock (or such other stock or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up.

All such shares shall be duly authorized and, when issued upon such exercise, shall be validly issued, fully paid and nonassessable, free and clear of all liens, security interests, charges and other encumbrances or restrictions on sale (other than any restrictions on transfer which may arise under any applicable federal or state securities laws) and free and clear of all preemptive rights. 11 12 9. EXCHANGE OF WARRANTS. Upon the surrender by the Holder of any Warrant or Warrants, properly endorsed, to the Company at the principal office of the Company, the Company will, subject to the provisions of Section 4 hereof, issue and deliver to or upon the order of such Holder, at the Company's expense, a new Warrant or Warrants of like tenor, in the name of such Holder or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct, calling in the aggregate on the face or faces thereof for the number of shares of Common Stock called for on the face or faces of the Warrant or Warrants so surrendered. 10. REPLACEMENT OF WARRANTS. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and (in the case of loss, theft or destruction) upon delivery of an indemnity agreement in an amount reasonably satisfactory to the Company, or (in the case of mutilation) upon surrender and cancellation of this Warrant, the Company at its expense (other than with respect to any legal fees incurred by the Holder which shall be at the Holder's expense) will issue, in lieu thereof, a new Warrant of like tenor. 11.
