          2.2  METHOD OF EXERCISE AND PAYMENT.

               (a) METHOD OF EXERCISE.  Subject to Section 2.1 hereof and 
          compliance with all applicable Federal and state securities laws, 
          the purchase right represented by this Warrant may be exercised, in 
          whole or in part, by the Warrant Holder by (i) surrender of this 
          Warrant and delivery of the Exercise Form attached hereto, duly 
          executed, at the principal office of the Company and (ii) payment 
          to the Company of an amount equal to the product of the then 
          applicable Exercise Price multiplied by the number of Warrant 
          Shares then being purchased.  At the election of the Warrant 
          Holder, the purchase price may be paid by surrender of this Warrant 
          for the full number of shares for which this Warrant is then 
          exercisable less that number of shares having a fair market value 
          equal to the aggregate exercise price.  For purposes of this 
          Section 2.2(a), fair market value shall be determined as follows: 
          (i) if the Company's Common Stock is publicly traded at the time of 
          exercise, fair market value shall be determined by appropriate 
          reference to the prices or quotes available for the most recent 
          purchases and sales of the Company's Common Stock as of the last 
          business day prior to the date of such exercise; and (ii) if the 
          Company's Common Stock is not publicly traded at the time of 
          exercise, fair market value shall be deemed to be the fair value of 
          the Common Stock as determined in good faith by the Company's Board 
          of Directors after taking into consideration all factors that it 
          deems appropriate, including, without limitation, recent sale and 
          offer prices of the Common Stock in private transactions negotiated 
          at arm's length.


                                      - 3 -


               (b)  METHOD OF PAYMENT.  Payment shall be made either by check 
          drawn on a United States bank and for United States funds made 
          payable to the Company, or by wire transfer of United States funds 
          for the account of the Company.

               (c) DELIVERY OF CERTIFICATE.  In the event of any exercise of 
          the purchase right represented by this Warrant, certificates for 
          the Warrant Shares so purchased shall be delivered to the Warrant 
          Holder within thirty (30) days of delivery of the Exercise Form 
          and, unless this Warrant has been fully exercised or has expired, a 
          new warrant representing the portion of the Warrant Shares with 
          respect to which this Warrant shall not then have been exercised 
          shall also be issued to the Warrant Holder within such thirty (30) 
          day period.

          2.3  SECURITIES ACT COMPLIANCE/RESTRICTIONS UPON TRANSFER.  Unless 
the issuance of the Warrant Shares shall have been registered under the 
Securities Act, as a condition of its delivery of certificates for the 
Warrant Shares, the Company may require the Warrant Holder (including the 
transferee of the Warrant Shares in whose name the Warrant Shares are to be 
registered) to deliver to the Company, in writing, representations regarding 
the Warrant Holder's sophistication, investment intent, acquisition for his 
own account and such other matters as are reasonable and customary for 
purchasers of securities in an unregistered private offering.   The Company 
may place conspicuously upon each Subsequent Warrant and upon each 
certificate representing the Warrant Shares a legend substantially in the 
following form, the terms of which are agreed to by the Warrant Holder 
(including such transferee):

          THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED SOLELY
          FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
          OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE SECURITIES LAW.  SUCH
          SHARES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN
          THE ABSENCE OF SUCH REGISTRATION OR AN OPINION OF COUNSEL SATISFACTORY
          TO THE COMPANY AND ITS COUNSEL THAT SUCH SALE, OFFER, PLEDGE OR
          HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY
          REQUIREMENTS OF THE ACT AND OF ANY APPLICABLE STATE SECURITIES LAWS
          UNLESS SOLD PURSUANT TO RULE 144 OF THE ACT.

The Company need not register a transfer of this Warrant or the Warrant 
Shares unless the conditions specified in such legend are satisfied.  Subject 
to the foregoing transfer restrictions set forth in this Section 2.3, this 
Warrant is transferable, in whole or in part, on the books of the Company, 
upon surrender of this Warrant to the Company, together with a written 
assignment duly executed by the Warrant Holder and delivery of funds 
sufficient to pay any transfer taxes payable by reason of such transfer.

          Section 3.  VALIDITY AND RESERVATION OF WARRANT SHARES.  The 
Company represents and warrants that all Warrant Shares issued upon exercise 
of this Warrant will be validly issued, fully paid, 

                                      - 4 -


nonassessable and not subject to preemptive or similar rights.  The Company 
agrees that, as long as this Warrant may be exercised, the Company will have 
authorized and reserved for issuance upon exercise of this Warrant a 
sufficient number of shares of Common Stock to provide for exercise in full 
of this Warrant.

          Section 4.  FRACTIONAL SHARE.  No fractional Warrant Shares shall 
be issued upon the exercise of this Warrant, and the number of Warrant shares 
to be issued shall be rounded to the nearest whole number.

          Section 5.  LIMITED RIGHTS OF WARRANT HOLDER.  The Warrant Holder 
shall not, solely by virtue of being the Warrant Holder of this Warrant, have 
any of the rights of a stockholder of the Company, either at law or equity, 
until this Warrant shall have been exercised.

          Section 6.  LOSS OF WARRANT.  Upon receipt by the Company of 
satisfactory evidence of the loss, theft, destruction or mutilation of this 
Warrant and either (in the case of loss, theft or destruction) reasonable 
indemnification and a bond satisfactory to the Company if requested by the 
Company or (in the case of mutilation) the surrender of this Warrant for 
cancellation, the Company will execute and deliver to the Warrant Holder, 
without charge, a new warrant of like denomination.

          Section 7.  CERTAIN ADJUSTMENTS OF EXERCISE PRICE.

          7.1 ADJUSTMENT OF EXERCISE PRICE.  The number, class and Exercise 
Price of securities for which this Warrant may be exercised are subject to 
adjustment from time to time upon the happening of certain events as 
hereinafter provided:

               7.1.1 RECAPITALIZATION.  If the outstanding shares of the 
          Company's Common Stock are divided into a greater number of shares 
          or the Company issues a stock dividend on its outstanding Common 
          Stock, the number of shares of Common Stock purchasable upon the 
          exercise of this Warrant shall be proportionately increased and the 
          Exercise Price shall be proportionately reduced and, conversely, if 
          the outstanding shares of Common Stock are combined into a smaller 
          number of shares of Common Stock, the number of shares of Common 
          Stock purchasable upon the exercise of this Warrant shall be 
          proportionately reduced and the Exercise Price shall be 
          proportionately increased.  The increases and reductions provided 
          for in this Section 7.1.1 shall be made with the intent and, as 
          nearly as practicable, the effect that neither the percentage of 
          the total equity of the Company obtainable on exercise of this 
          Warrant nor the price payable for such percentage shall be affected 
          by any event described in this Section 7.1.1.

               7.1.2  MERGER OR REORGANIZATION, ETC.  In the event of any 
          change in the Common Stock through merger, consolidation, 
          reclassification, reorganization, partial or complete liquidation 
          or other change in the capital structure of the Company (not 
          including the issuance of additional shares of capital stock other 
          than by stock dividend or stock split), then, as a condition of 
          such change in the capital structure of the Company, appropriate 
          and adequate 

                                      - 5 -


          provision shall be made so that the Warrant Holder of this Warrant 
          will have the right thereafter to receive upon the exercise of this 
          Warrant the kind and amount of shares of stock or other securities 
          or property to which it would have been entitled if immediately 
          prior to such merger, consolidation, reclassification, 
          reorganization, recapitalization or other change in the capital 
          structure, it had held the number of shares of Common Stock then 
          obtainable upon the exercise of this Warrant.  In any such case 
          appropriate adjustment shall be made in the applications of the 
          provisions set forth herein with respect to the rights and interest 
          thereafter of the Warrant Holder, to the end that the provisions 
          set forth herein shall thereafter be applicable, as nearly as 
          reasonably may be, in relation to any shares of stock or other 
          property thereafter deliverable upon the exercise of this Warrant.  

          7.2  NOTICE OF ADJUSTMENT.  Whenever an event occurs requiring any 
adjustment to be made pursuant to Section 7.1, the Company shall promptly 
file with its Secretary or an Assistant Secretary at its principal office and 
with its stock transfer agent, if any, a certificate of its chief executive 
officer specifying such adjustment, setting forth in reasonable detail the 
acts requiring such adjustment, and stating such other facts as shall be 
necessary to show the manner and figures used to compute such adjustment.  
Such chief executive officer's certificate shall be made available at all 
reasonable times for inspection by the Warrant Holder.  Promptly (but in no 
event more than 30 days) after each such adjustment, the Company shall give a 
copy of such certificate by certified mail to the Warrant Holder.

          Section 8.  SUBDIVISION OF WARRANT.  At the request of the Warrant 
Holder in connection with a transfer of a portion of this Warrant upon 
surrender of this Warrant for such purpose to the Company at its principal 
office, the Company at its expense (except for any transfer tax payable) will 
issue and exchange therefor new Warrants of like tenor and date representing 
in the aggregate the amount of the Warrant Shares.

          Section 9.  REGISTRATION RIGHTS.

          9.1  DEFINITIONS.  For purposes of this Section 9:

               (a)  The term "register", "registered" and "registration" 
          refer to a registration effected by preparing and filing a 
          registration statement or similar document in compliance with the 
          Securities Act, and the declaration or ordering of effectiveness of 
          such registration statement or document;

               (b)  The term "Registrable Securities" means any Common Stock 
          issued or issuable upon exercise of this Warrant, excluding, 
          however, any Registrable Securities sold by a person in a 
          transaction in which his rights are not assigned under Section 9.6 
          hereof.

               (c)  The number of shares of "Registrable Securities then 
          outstanding" shall be determined by the number of shares of Common 
          Stock outstanding which are, and the number of shares of Common 
          Stock issuable pursuant to then exercisable or convertible 
          securities which are, Registrable Securities; and


                                     - 6 -


               (d)  The term "Holder" means any person owning or having the 
          right to acquire Registrable Securities or any assignee thereof in 
          accordance with Section 9.10 hereof. 

          9.2  COMPANY REGISTRATION.

               (a)  If the Company proposes to register (including for this 
          purpose a registration effected by the Company for shareholders 
          other than the Holders) any of its capital stock or other 
          securities under the Securities Act in connection with the public 
          offering of such stock or securities solely for cash (other than a 
          registration on any form which does not include substantially the 
          same information as would be required to be included in a 
          registration statement covering the sale of the Registrable 
          Securities), the Company shall, each such time, promptly give each 
          Holder written notice of such registration together with a list of 
          the jurisdictions in which the Company intends to attempt to 
          qualify such securities under the applicable blue sky or other 
          state securities laws. Upon the written request of each Holder 
          given within twenty (20) days after giving of such written notice 
          by the Company in accordance with Section 11.2, the Company shall, 
          subject to the limitations set forth in subsection 9.2(b) below, 
          cause to be registered under the Securities Act all of the 
          Registrable Securities that each such Holder has requested to be 
          registered.

               (b)  The right of any Holder to registration pursuant to this 
          Section 9.2 shall 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 their securities through such 
          underwriting shall (together with the Company and the other holders 
          distributing their securities through such underwriting) enter into 
          an underwriting agreement in customary form with the underwriter or 
          underwriters selected for underwriting by the Company.  
          Notwithstanding any other provision of this Section 9.2, if the 
          underwriter determines that marketing factors require a limitation 
          of the number of shares to be underwritten, and:  (i) if such 
          registration is the first registered offering of the sale of the 
          Company's securities to the public, then the underwriter may 
          (subject to the allocation priority set forth below) exclude some 
          or all Registrable Securities from such registration and 
          underwriting; or (ii) if such registration is other than the first 
          registered offering of the sale of the Company's securities to the 
          general public, then the underwriter may (subject to the allocation 
          priority set forth below) limit the number of Registrable 
          Securities to be included in the registration and underwriting to 
          not less than twenty-five percent (25%) of the number of securities 
          included therein.  In the event of such a limitation, the Company 
          shall so advise all Holders requesting registration, and the number 
          of shares of securities that may be included in the registration 
          and underwriting shall be allocated in the following manner:  The 
          securities of the Company held by officers and directors of the 
          Company (other than Registrable Securities and other than 
          securities held by persons who, by virtue of contracts with the 
          Company, are entitled to include their securities in such 
          registration) shall be excluded from such registration and 
          underwriting to the extent required by such limitation, and, if a 
          further limitation of the number of shares is required, the number 
          of shares that may be included in the 


                                      - 7 -


          registration and underwriting shall be allocated among all other 
          holders (including Holders of Registrable Securities) thereof in 
          proportion, as nearly as practicable, to the respective amounts of 
          securities (including Registrable Securities) which would otherwise 
          be entitled to inclusion in such registration held by such Holders 
          or holders at the time of filing the registration statement. If any 
          Holder disapproves of the terms of any such underwriting, he may 
          elect to withdraw therefrom by written notice to the Company and 
          the underwriter.  Any Registrable Securities or other securities 
          excluded or withdrawn from such underwriting shall be withdrawn 
          from such registration.

               (c)  The Company's obligations under this Section 9.2 shall 
          terminate with respect to any Holder one year after the Expiration 
          Date.

          9.3 EXPENSES OF REGISTRATION.

               (a)  As used in this Section 9.3, "Registration Expenses" 
          shall mean all expenses incurred by the Company in complying with 
          Section 9.2, hereof, including, without limitation, all 
          registration and filing fees, printing expenses, fees and 
          disbursements of counsel for the Company, fees and disbursements of 
          a single counsel for all Holders, blue sky fees and expenses, and 
          the expense of any special audits incident to or required by any 
          such registration (but excluding the compensation of regular 
          employees of the Company which would be paid in any event by the 
          Company); and "Selling Expenses" shall mean all underwriting 
          discounts and selling commissions applicable to the sale.

               (b)  All Registration Expenses incurred in connection with any 
          registration, qualification or compliance pursuant to this Section 
          9 shall be borne by the Company; and all Selling Expenses shall be 
          borne by the Holders of the securities so registered pro rata on 
          the basis of the number of shares so registered and sold.

          9.4  DELAY OF REGISTRATION.  No Holder shall have any right to 
obtain or seek an  injunction restraining or otherwise delaying any such 
registration as the result of any controversy that might arise with respect 
to the interpretation or implementation of this Section 9.

          9.5  INDEMNIFICATION.  In the event any Registrable Securities are 
included in a registration statement under this Section 9:

               (a)  To the extent permitted by law, the Company will 
          indemnify and hold harmless each Holder, the officers, directors 
          and agents of each Holder, any underwriter (as defined in the 
          Securities Act) for such Holder and each person, if any, who 
          controls such Holder or underwriter within the meaning of the 
          Securities Act or the 1934 Act, against any losses, claims, 
          damages, or liabilities (joint or several) to which they may become 
          subject under the Securities Act, the 1934 Act or other federal or 
          state law or common law doctrine related to fraud, insofar as such 
          losses, claims, damages, or liabilities (or actions in respect 
          thereof) arise out of or are based upon any of the following 
          statements, omissions or violations (collectively a 



                                      - 8 -


          "Violation"):  (i) any untrue statement or alleged untrue statement 
          of a material fact contained in such registration statement, 
          including any preliminary prospectus or final prospectus contained 
          therein or any amendments or supplements thereto, (ii) the omission 
          or alleged omission to state therein a material fact required to be 
          stated therein, or necessary to make the statements therein not 
          misleading, or (iii) any violation or alleged violation by the 
          Company of the Securities Act, the 1934 Act, any state securities 
          law or any rule or regulation promulgated under the Securities Act, 
          the 1934 Act or any state securities law; and the Company will pay 
          as incurred any legal or other expenses reasonably incurred by each 
          such Holder, officer, director, agent, underwriter, or controlling 
          person in connection with investigating or defending any such loss, 
          claim, damage, liability, or action; provided, however, that the 
          indemnity agreement contained in this subsection 9.8(a) shall not 
          apply to amounts paid in settlement of any such loss, claim, 
          damage, liability, or action if such settlement is effected without 
          the consent of the Company (which consent shall not be unreasonably 
          withheld), nor shall the Company be liable in any such case for any 
          such loss, claim, damage, liability, or action to the extent that 
          it arises out of or is based upon a Violation which occurs in 
          reliance upon and in conformity with written information furnished 
          expressly for use in connection with such registration by any such 
          Holder, officer, director, agent, underwriter or controlling 
          person; provided further, however, that the foregoing indemnity 
          agreement is subject to the condition that, insofar as it relates 
          to any such untrue statement, alleged untrue statement, omission, 
          or alleged omission made in a preliminary prospectus but eliminated 
          or remedied in the amended prospectus on file with the SEC at the 
          time the registration statement becomes effective, or in the 
          amended prospectus filed with the SEC pursuant to Rule 424(b) (the 
          "Final Prospectus"), such indemnity agreement shall not inure to 
          the benefit of any underwriter, or any Holder or any party 
          otherwise entitled to indemnification hereunder (if there is no 
          underwriter), if a copy of the Final Prospectus was not furnished 
          to the person or entity asserting the loss, liability, claim, or 
          damage at or prior to the time such action is required by the 
          Securities Act.

               (b)  Promptly after receipt by an indemnified party under this 
          Section 9.5 of notice of the commencement of any action (including 
          any governmental action), such indemnified party will, if a claim 
          in respect thereof is to be made against any indemnifying party 
          under this Section 9.5, notify the indemnifying party in writing of 
          the commencement thereof and the indemnifying party shall have the 
          right to participate in, and, to the extent the indemnifying party 
          so desires, jointly with any other indemnifying party similarly 
          noticed, to assume the defense thereof with counsel mutually 
          satisfactory to the parties; provided, however, that an indemnified 
          party shall have the right to retain its own counsel, with the fees 
          and expenses to be paid by the indemnifying party, if the 
          indemnifying party shall not have engaged counsel within a 
          reasonable period of time to assure the defense of such action, or 
          if representation of such indemnified party by the counsel retained 
          by the indemnifying party would be inappropriate due to actual or 
          potential differing interests between such indemnified party and 
          any other party represented by such counsel in such proceeding.  
          The failure to notify an indemnifying party within a reasonable 
          time of the commencement of any such action, if prejudicial to its 
          ability to defend such action, shall relieve such indemnifying 
          party of any liability to the indemnified party 


                                      - 9 -


          under this Section 9.5, but the omission so to notify the 
          indemnifying party will not relieve it of any liability that it may 
          have to any indemnified party otherwise than under this Section 9.5.

          9.6  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the 
Company to register Registrable Securities pursuant to this Section 9 may be 
assigned by a Holder to:  (a) any entity which is controlling, controlled by 
or under common control with any Warrant Holder, any member of Warrant 
Holder's immediate family (being limited to spouses and lineal ancestors and 
descendants) or any partnership composed of, or trust for the primary benefit 
of, the Warrant Holder or members of such Warrant Holder's immediate family; 
(b) a general or limited partner of the Warrant Holder; or (c) any other 
transferee or assignee of such securities upon the transfer or assignment of 
securities representing at least twenty-five percent (25%) of the total 
number of shares of Warrant Shares purchased by the Warrant Holder pursuant 
to this Warrant; provided that the Company is, within a reasonable time after 
any such transfer, furnished with written notice of the name and address of 
such transferee or assignee and the securities with respect to which such 
registration rights are being assigned and an Assumption Agreement in the 
form attached as EXHIBIT A to this Warrant executed by the party receiving 
the assignment of registration rights pursuant to this Section 9; and 
provided, further, that such assignment shall be effective only if 
immediately following such transfer the further disposition of such 
securities by the transferee or assignee is restricted under the Securities 
Act.

          9.7  "MARKET STAND-OFF AGREEMENT".  The Warrant Holder hereby 
agrees that it shall not, to the extent requested by the Company and any 
underwriter of securities of the Company in a registered offering in which 
such Warrant Holder had a right to sell Registrable Securities hereunder, 
sell or otherwise transfer or dispose of any Registrable Securities during 
the one hundred eighty (180) day period following the effective date of such 
registration statement; PROVIDED, however, that:

               (a)  Such agreement shall be applicable only to the first such 
          registration statement of the Company which covers shares (or 
          securities) to be sold on its behalf to the public in an 
          underwritten offering; and

               (b)  Such agreement is conditioned upon all employees, 
          officers and directors of the Company and all other persons with 
          contractual registration rights (whether or not pursuant to this 
          Warrant) entering into similar agreements.

          In order to enforce the foregoing covenant, the Company may impose 
stop-transfer instructions with respect to the Registrable Securities of the 
Warrant Holder (and the shares or securities of every other person subject to 
the foregoing restriction) until the end of such ninety (90) day period.

          9.8  MODIFICATION OF RIGHTS.  Any of the terms and provisions of 
this Section 9 shall be subject to modification from time to time upon 
written agreement between at least fifty-one percent (51%) in interest of the 
Holders and the Company.

          Section 10.  REPRESENTATIONS AND WARRANTIES.  


                                     - 10 -



          10.1  BY WARRANT HOLDER.  The Warrant Holder represents and 
warrants to the Company as follows:

               (a) This Warrant and the Warrant Shares issuable upon exercise 
          thereof are being acquired for its own account, for investment and 
          not with a view to, or for resale in connection with, any 
          distribution or public offering thereof within the meaning of the 
          Securities Act.  Upon exercise of this Warrant, the Warrant Holder 
          shall, if so requested by the Company, confirm in writing, in a 
          form satisfactory to the Company, that the securities issuable upon 
          exercise of this Warrant are being acquired for investment and not 
          with a view toward distribution or resale.

               (b)  The Warrant Holder understands that the Warrant and the 
          Warrant Shares have not been registered under the Securities Act by 
          reason of their issuance in a transaction exempt from the 
          registration and prospectus delivery requirements of the Act 
          pursuant to Section 4(2) or Section 4(6) thereof, and that they 
          must be held by the Warrant Holder indefinitely, and that the 
          Warrant Holder must therefore bear the economic risk of such 
          investment indefinitely, unless a subsequent disposition thereof is 
          registered under the Securities Act or is exempted from such 
          registration.

               (c) The Warrant Holder has such knowledge and experience in 
          financial and business matters that it is capable of evaluating the 
          merits and risks of the purchase of this Warrant and the Warrant 
          Shares purchasable pursuant to the terms of this Warrant and of 
          protecting its interests in connection therewith.

               (d)  The Warrant Holder is able to bear the economic risk of 
          the purchase of the Warrant Shares pursuant to the terms of this 
          Warrant.

          10.2  BY COMPANY.  The Company represents and warrants to the 
Warrant Holder those representations and warranties as set forth in Section 
3.1 of that certain Subordinated Promissory Note Purchase Agreement, of even 
date herewith, between the Company and the Purchasers named therein.

          Section 11.  MISCELLANEOUS.
