VOID AFTER 5:00 P.M. JULY 31, 1999 Warrants CLASS B WARRANT NO. FIELD(8) [REXEX CORP. LOGO] CLASS B WARRANT CERTIFICATE THIS CERTIFIES THAT, for value received, FIELD(3), or any registered assigns (the "Holder"), is the owner of the number of warrants (the "Warrants") specified above of RENEX CORP., a Florida corporation (the "Company"). Each Warrant entitles the holder hereof to purchase, subject to the terms and conditions set forth in this certificate one fully paid and non-assessable share of the Company's Common Stock, $.001 par value (the "Shares") commencing on the date hereof and continuing through July 31, 1999 (the "Exercise Period") upon the presentation and surrender of this Warrant Certificate, with the form of election to purchase attached hereto, duly executed, to the Company at its principal office, accompanied by payment of $2.00 for every share of Common Stock so purchased hereunder (the "Exercise Price"). Each Warrant represented hereby is exercisable at the option of the registered Holder, but no fractional shares of Common Stock will be issued and the Holder may exercise only a whole number of Warrants. In lieu of fractional shares of Common Stock, the Company shall pay to the holder hereof an amount equal to the current value of such fraction computed (a) if the Shares shall then be listed or admitted to trading on any national securities exchange, on the basis of the last reported sale price of the Shares on such exchange prior to the date of exercise, (b) if the Shares shall not then be so listed or admitted, on the basis of the average of the high and low bid prices of the shares in the over-the-counter market, as reported by NASDAQ or any successor thereto, on the last business day prior to the date of exercise, or (c) if there is no market for the Shares, the fair market value as determined in good faith by the Company's Board of Directors. In the cash of the exercise of less than all of the Warrants represented by this Warrant Certificate, the Company will cancel this Certificate upon surrender thereof and shall execute and deliver a new Warrant Certificate for the balance of such Warrants. The term "Expiration Date" shall mean 5:00 P.M. Eastern Standard Time on July 25, 1999. If such date shall be a holiday or a day in which banks are authorized to close, then the Expiration Date shall mean 5:00 P.M. Eastern Standard Time, on the next following day which is not a holiday or a day on which banks are authorized to close. Prior to due presentment for transfer of this Warrant Certificate, the Company may deem and treat the person in whose name this Warrant Certificate is registered on the books of the Company as the absolute owner hereof for all purposes and that the Company shall not be affected by any notice to the contrary. ADDITIONAL PROVISIONS OF THIS WARRANT FOLLOW DATED this 31st day of July, 1996. RENEX CORP., a Florida corporation Attest: By: ----------------------------- ------------------------------- BRYAN W. BAUMAN, JAMES P. SHEA, President Assistant Secretary 2 1. ANTI-DILUTION ADJUSTMENTS. (a) In case the Company shall at any time prior to the Exercise of the Warrants declare a dividend or any distribution payable in any class of the Company's Shares now outstanding or to be outstanding to which the Exercise of the Warrants pertains, then the holder hereof, upon the Exercise of the Warrants after the record date for the determination of holders of Shares entitled to receive such dividend or distribution, shall be entitled to receive upon Exercise of the Warrants, in addition to the number of Shares as to which this Warrant Certificate is exercised, such additional Shares as such holder would have received had the Warrants been exercised immediately prior to such record date. (b) In case the Company shall at any time prior to the Exercise of the Warrants effect a recapitalization or reclassification of such character that the Shares shall be changed into or become exchangeable for a larger or smaller number of Shares, then upon the effective date thereof, the number of Shares which the holder hereof shall be entitled to purchase upon Exercise of the Warrants shall be increased or decreased, as the case may be, in direct proportion to the increase or decrease in the number of Shares by reason of such recapitalization or reclassification, and the Purchase Price Per Share of such recapitalized or reclassified Shares be proportionately decreased and in the case of a decrease in the number of Shares, be proportionately increased. (c) Subject to the provisions contained in Paragraph 1(g) herein, in case the Company shall at any time prior to the Exercise of the Warrants issue or sell any Shares or any other securities convertible into Shares or any options or warrants to purchase Shares (except as provided in subsection (a) of this Paragraph 1, pursuant to incentive compensation plans, pursuant to options to officers or employees or issuance of any shares upon the conversion of warrants, or other rights or options now outstanding for a consideration per Share less than $1.00, then forthwith upon such issue or sale the Purchase Price Per Share (until another such issue or sale) shall be reduced to a price (calculated to the nearest full cent) determined by dividing (i) an amount equal to the sum of (A) the product obtained by multiplying (x) the total number of Shares outstanding immediately prior to such issue or sale, by (y) the Purchase Price Per Share in effect immediately prior to such issue or sale plus (B) the aggregate amount of any consideration in connection with such issue or sale, by (ii) the total number of Shares outstanding immediately after such issue or sale. Simultaneously with such reduction in the Purchase Price Per Share, the number of Shares issuable upon Exercise of the Warrants shall be increased (to the nearest full Share) to the number obtained by multiplying the Purchase Price Per Share in effective immediately prior to such reduction by the number of Shares then issuable upon Exercise of the Warrants and dividing the product so obtained by the reduced Purchase Price Per Share. For purposes of this subsection 1(c) the consideration in connection with any such issue or sale shall be the initial offering price for the sale of such shares or other securities, options or warrants before deducting therefrom any commissions or other expenses paid or incurred by the Company in connection with the issue or sale of such securities, options or warrants plus any additional cash receivable by the Company upon conversion or exercise of such other securities, options or warrants, except that in the event that any portion of such consideration is a consideration other than cash, the amount of such consideration other than cash shall be the value thereof as determined in good faith by the Board of Directors of the Company. In the event that the conversion price or exercise price of any securities convertible into Shares or options or warrants to purchase Shares is not specified at the time of the issue or sale of such securities, options or warrants, the amount thereof, for purposes only of this subsection 1(c), shall be as determined in good faith by the Board of Directors of the Company. In the event of the issuance or sale by the Company of any securities convertible into Shares or any options or warrants to purchase Shares (except as provided in subsection (a) of this Paragraph 1 or pursuant to incentive compensation plans or options to officers or employees) the Company shall be deemed to have issued the maximum number of Shares into which such convertible securities may be converted or the maximum number of Shares deliverable upon the exercise of such options or warrants, as the case may be. On the expiration of such options or warrants or the termination of such right to convert, the Purchase Price Per Share shall be readjusted based upon the number of Shares actually delivered upon the exercise of such options or warrants or upon the conversion of such securities. Except as provided in the preceding sentence, no further adjustment of the Purchase Price Per Share shall be made as a result of the actual issuance of Shares upon the exercise of such options or warrants or the conversion of such securities. -2- 3 (d) In case the Company shall at any time prior to the Exercise of the Warrants consolidate or merge with any other corporation or transfer all or substantially all of its assets to any other corporation preparatory to a dissolution, then the Company shall, as a condition precedent to such transaction, cause effective provision to be made so that the holder hereof upon the Exercise of the Warrants after the effective date of such transaction shall be entitled to receive the kind and amount of shares, evidences of indebtedness and/or other securities or property receivable on such transaction by a holder of the number of Shares as to which this Warrant were exercisable immediately prior to such transaction (without giving effect to any restriction upon such exercise); and, in any such case, appropriate provision shall be made with respect to the rights and interests of the holder hereof to the end that the provisions of this Warrant shall thereafter be applicable (as nearly as may be practicable) with respect to any Shares, evidences of indebtedness or other securities or assets thereafter deliverable upon Exercise of the Warrants. (e) The term "Purchase Price Per Share" as used in this Paragraph 1 shall mean the exercise price specified in this Warrant Certificate until the occurrence of an event stated in subsection (b) or (c) of this Paragraph 3 and thereafter shall mean said price as adjusted from time to time in accordance with the provisions of said subsections. No such adjustment shall be made unless such adjustment would change the then Purchase Price Per Share by $.01 or more; provided, however, that all adjustments not so made shall be deferred and made when the aggregate thereof would change the then Purchase Price Per Share by $.01 or more. No adjustment made pursuant to any provision of this Paragraph 3 shall have the effect of increasing the total consideration payable upon Exercise of the Warrants in respect of all the Shares purchasable hereunder. (f) In the event that at any time, as a result of an adjustment made pursuant to this Paragraph 3, the holder of this Warrant Certificate shall become entitled to purchase upon Exercise of the Warrants, shares, evidences of indebtedness or other securities or assets (other than Shares) then, wherever appropriate, all references herein to Shares shall be deemed to refer to and include such shares, evidences of indebtedness or other securities or assets; and thereafter the number of such shares, evidences of indebtedness or other securities or assets shall be subject to adjustment from time to time in a manner and upon terms as nearly equivalent as practicable to the provisions of this Paragraph 3. (g) Notwithstanding anything herein to the contrary, no adjustment shall be made to the Purchase Price Per Share or the number of shares issuable upon exercise of this Warrant upon the issuance of any securities issued in connection with any of the following (i) incentive compensation plans, (ii) upon grant of options under any stock option plans approved by the corporation's shareholders or the exercise and issuance of Common Stock thereunder, (iii) upon conversion of any shares of Series A Preferred Stock and the issuance of Common Stock pursuant thereto, (iv) exercise of any warrants, rights or options now outstanding (v) the sale and issuance of common stock for a purchase price of $1.00 or more or (vi) the sale of securities convertible or exercisable into common stock which securities conversion or exercise price is $1.00 or greater. 2. NOTICES TO WARRANT HOLDER. If, at any time prior to the expiration or Exercise of the Warrants, any of the following events shall occur: (a) the Company shall declare any dividend payable in securities upon its Shares or make any distribution (other than a cash dividend payable out of earned surplus to the holders of its Shares; or (b) the Company shall offer to the holders of its Shares any additional shares of the Company or securities convertible into shares of the Company or any right to subscribe therefor; or (c) a dissolution, liquidation or winding-up of the Company (other than in connection with a consolidation or merger) or a transfer of all or substantially all of its assets shall be proposed; then in any one or more of said events, the Company shall give to the holder of this Warrant, by first-class mail, postage prepaid, at the address of such holder as shown on the books of the Company, not less than twenty (20) days' prior notice of the date on which: (i) The books of the Company shall be closed or a record taken for determination of the shareholders entitled to such dividend, distribution or subscription rights; or (ii) the books of the Company shall be closed or record taken for determination of the shareholders entitled to vote on such proposed dissolution, liquidation, winding-up or transfer. -3- 4 3.

BENEFITS OF THIS WARRANT. Nothing in this Warrant Certificate shall be construed to confer upon any person other than the Company and the holder of this Warrant Certificate any legal or equitable right, remedy or claim under this Warrant Certificate and this Warrant Certificate shall be for the sole and exclusive benefit of the Company and the holder of this Warrant Certificate. 5. UNREGISTERED SECURITIES. The Holder of this Warrant may not exercise the Warrant if such exercise would be in violation of the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the "Act"). Any subsequent resale of the Shares may be made only upon proof by the Holder to the satisfaction of counsel for the Company that the resale will not result in a violation of the Act. The Holder shall make such representations and supply such information as may, in the opinion of counsel for the Company, be appropriate or advisable in view of the then existence or nonexistence of an effective registration statement under the Act covering the issuance of the Shares of the Company. The Holder hereby agrees that the Company may place a stop order covering the transfer of any Shares issued pursuant to the exercise of the Warrant with the Transfer Agent of such shares and may place upon the certificates representing such shares a legend indicating such restrictions. 6. PIGGY-BACK REGISTRATION RIGHTS. If the Company shall at any time file a new registration statement under the Securities Act relating to shares of its Common Stock (other than on Forms S-4 or S-8), then it shall give thirty days' prior written notice of its intention to do so to the Holder and, if requested in writing by the Holder hereof not more than twenty days after his receipt of such notice, the Company shall include in said registration statement the Shares issuable or theretofore issued upon exercise of the Warrant as the Holder hereof shall request; provided, however, that if there is an underwriter selected by the Company for such offering and sale, and it advises that, in its professional opinion the number of shares of Common Stock proposed to be sold by the Company and the holder of the Warrant is greater than the number of shares of Common Stock which it believes may be sold, then the number of shares of Common Stock to be sold shall first be allocated to the Company and any balance thereafter shall be allocated to the Holder. If the Company includes the Shares in such registration statement, and if the Company shall so request, the Holder shall agree in writing not to sell any other shares of Common Stock owned by the Holder for a period specified by the Company, but not exceeding 180 days from the effective date of such registration statement if the underwriter of the Shares then being registered so requests. The Company shall bear all costs and expenses of the registration statement (and all amendments and supplements thereto) relating to the registration of the Shares, including printing, legal and accounting expenses, and SEC filing fees, expenses and transfer agency fees, but the Company shall have no obligation to pay or otherwise bear (i) any portion of the fees or disbursements of any counsel which any Holder may retain in connection with the registration of the Shares, (ii) any portion of the underwriter's commission, discounts and expenses attributable to such Shares being offered and sold by the Warrant Holder or (iii) any applicable stock transfer taxes. Prior to the effective date of any registration statement filed hereunder, the Company and the persons requesting the registration will execute an agreement providing for indemnification of each other in form satisfactory to the Company. 7. LOSS OR DESTRUCTION OF WARRANT CERTIFICATE. If this Warrant Certificate shall be surrendered mutilated to the Company, or if the Company shall have received evidence to its satisfaction of its destruction, loss or theft, and there be delivered to the Company such security or indemnity as may be reasonably required by it to hold it harmless, then the Company shall execute and deliver in lieu of this Warrant Certificate, or in substitution for the mutilated Warrant Certificate (upon surrender of such Warrant Certificate) a new Warrant Certificate. 8. MODIFICATIONS.
