          (a) Termination and Expiration.  If not earlier exercised, the Warrant
              --------------------------                                        
              shall expire on the date (the "Expiration Date") that is the
              earlier of (i) eighteen (18) months after the consummation of a
              firmly underwritten public offering pursuant to the Securities Act
              of 1933, as amended (the "Securities Act"), by the Company of its

              "Qualified IPO") and (ii) 60 months after the date first set forth
              above.

          (b) Exceptions.  Notwithstanding the foregoing, in the event the
              ----------                                                  
              Company is proposed to be acquired in a bona fide transaction
              (i.e., not a mere recapitalization, reincorporation for the
              purpose of changing corporate domicile, 

 
              or similar transaction) (the "Acquisition"), regardless of the
              form of the transaction (e.g., merger, consolidation, exclusive
              license, sale or lease of assets or sale of stock), the Company
              shall give the Holder not less than fifteen (15) business days
              notice of the record date for determining the shareholders of the
              Company entitled to vote on (or otherwise approve) the
              Acquisition; the Company shall provide the Holder with all
              information with respect to the Acquisition that is otherwise
              provided to shareholders of the Company at such time and from time
              to time during the pendency of the Acquisition, including (but not
              limited to) the proposed price to be paid in the proposed
              Acquisition; the Holder shall have the right to exercise same on
              or prior to the record date of shareholders eligible to vote (or
              otherwise approve) with respect to the proposed Acquisition; if
              the Warrant is not exercised on or prior to such record date, the
              Warrant shall expire upon the occurrence of the consummation of
              the Acquisition, provided that if the Acquisition is not
              consummated, then the Holder shall be entitled to revoke the
              exercise of this Warrant pursuant to the operation of this Section
              1(a).

     2.  EXERCISE OF WARRANT

     The purchase rights represented by this Warrant are exercisable by the
registered holder hereof, in whole or in part, at any time and from time to time
at or prior to the Expiration Time by the surrender of this Warrant and the
Notice of Exercise form attached hereto duly executed to the principal executive
office of the Company at the address set forth on the signature page hereof (or
such other office or agency of the Company as it may designate by notice in
writing to the registered holder hereof at the address of such holder appearing
on the books of the Company), and upon payment of the Exercise Price for the
shares thereby purchased by cash, check or wire transfer or, at the election of
the Warrantholder, may be made on a "net exercise" basis, in which event the
Company shall issue the Warrantholder a number of shares of Common Stock
computed using the following formula:
 
                                 Y = X(A-B)/A

Where:
 
     X  =  the number of equal shares of Common Stock for which this Warrant is
           exercisable;
 
     Y  =  the number of shares of Common Stock to be issued to the Holder;
 
     A  =  the Fair Market Value (as defined below) of one share of the
           Company's Common Stock on the date of conversion of this Warrant; and
           
     B  =  the Exercise Price for one share of the Company's Common Stock under
           this Warrant.

                                      -2-

 
     If the above calculation results in a negative number, then no shares of
Warrant Stock shall be issued or issuable upon conversion of this Warrant.

     "Fair Market Value" of a share of Common Stock shall mean:

     (a)  if this Warrant is exercised (i) immediately prior to a Qualified IPO,
          and (ii) if the Company's Registration Statement on Form S-1 or SB-2
          (or successor or equivalent forms) relating to such public offering
          has been declared effective by the Securities and Exchange Commission,
          then the Fair Market Value per share shall be the price per share to
          the public as specified in the final prospectus with respect to the
          offering;

     (b)  if this Warrant is exercised after the consummation of a Qualified
          IPO, then:

          (i)  if traded on a securities exchange, the Fair Market Value per
               share of Common Stock shall be deemed to be the average of the
               closing sales prices of the Company's Common Stock over a ten
               (10) day trading period (or for such shorter period as the
               Company's Common Stock may have been trading) ending three (3)
               days before the Exercise Date, or

          (ii) if traded over-the-counter, the Fair Market Value per share of
               Common Stock shall be deemed to be the average of the prices of
               the Company's Common Stock quoted on The Nasdaq Stock Market,
               Inc. (or NASD bulletin board or any similar system) over the ten
               (10) day trading period (or for such shorter period as the
               Company's Common Stock has been trading) ending three (3) days
               before the Exercise Date; or

     (c)  if this Warrant is exercised prior to a Qualified IPO (except as
          provided in clause (a) above), the Fair Market Value per share of
          Common Stock shall be equal to an amount determined in good faith by
          the Company's Board of Directors, but shall in no event be less than
          the actual sale price per share in the Company's latest financing.

     Upon exercise of this Warrant in accordance with this Section 2, the holder
of this Warrant shall be entitled to receive from the Company a stock
certificate in proper form representing the number of shares of Warrant Stock so
purchased, and a new Warrant in substantially identical form and dated as of
such exercise for the purchase of that number of shares of Warrant Stock equal
to the difference, if any, between the number of shares of Warrant Stock subject
hereto and the number of shares of Warrant Stock as to which this Warrant is so
exercised.

     3.  CONVERSION OF WARRANT

     The Holder shall have the right to convert this Warrant, in whole or in
part, at any time (including, but not limited to, the occurrence of an
Acquisition of the Company) and from time to time at or prior to the Expiration
Time by the payment of the Exercise Price (as hereinafter defined), and
surrender of this Warrant and the Notice of Conversion form attached hereto duly
executed to the principal executive office of the Company at the address set
forth on the signature page hereof (or such other office or agency of the
Company as it may designate by notice in writing to the Holder at the address of
such Holder appearing on the books of the Company), into shares of Warrant Stock
as 

                                      -3-

 
provided in this Section 3. Payment of the Exercise Price may be made by cash,
check or wire transfer or, at the election of the Warrantholder, may be made on
a "net exercise" basis, in which event the Company shall issue the Warrantholder
a number of shares of Common Stock computed using the formula set forth in
Section 2.

     Upon conversion of this Warrant in accordance with this Section 3, the
Holder hereof shall be entitled to receive a certificate for the number of
shares of Warrant Stock determined in accordance with the foregoing, and a new
Warrant in substantially identical form and dated as of such conversion for the
purchase of that number of shares of Warrant Stock equal to the difference, if
any, between the number of shares of Warrant Stock subject hereto and the number
of shares of Warrant Stock as to which this Warrant is so converted.

     4.  ISSUANCE OF SHARES; NO FRACTIONAL SHARES OR SCRIP

     Certificates for shares purchased hereunder or issuable upon conversion
hereof shall be delivered to the Holder promptly after the date on which this
Warrant shall have been exercised or converted in accordance with the terms
hereof.  The Company hereby represents and warrants that all shares of Warrant
Stock which may be issued upon the exercise or conversion of this Warrant will,
upon such exercise or conversion, be duly and validly authorized and issued,
fully paid and nonassessable and free from all liens and encumbrances in respect
of the issuance thereof (other than liens or encumbrances created by or imposed
upon the Holder of the Warrant Stock).  The Company agrees that the shares so
issued shall be and shall for all purposes be deemed to have been issued to such
Holder as the record owner of such shares as of the close of business on the
date on which this Warrant shall have been exercised or converted in accordance
with the terms hereof.  No fractional shares or scrip representing fractional
shares shall be issued upon the exercise or conversion of this Warrant.  With
respect to any fraction of a share called for upon the exercise or conversion of
this Warrant, an amount equal to such fraction multiplied by the Fair Market
Value of a share of Warrant Stock on the date of exercise or conversion shall be
paid in cash or check to the Holder.

     5.  CHARGES, TAXES AND EXPENSES

     Issuance of certificates for shares of Warrant Stock upon the exercise or
conversion of this Warrant shall be made without charge to the Holder for any
issue or transfer tax or other incidental expense in respect of the issuance of
such certificate, all of which taxes and expenses shall be paid by the Company,
and such certificates shall be issued in the name of the Holder or in such name
or names as may be directed by the Holder provided, however, that in the event
certificates for shares of Warrant Stock are to be issued in a name other than
the name of the Holder, this Warrant when surrendered for exercise or conversion
shall be accompanied by the Assignment Form attached hereto duly executed by the
Holder.

     6.   RIGHTS AS SHAREHOLDERS

     No Holder of this Warrant, as such, shall be entitled to vote upon any
matter submitted to shareholders at any meeting thereof, or to receive notice of
meetings, or be deemed the holder of 

                                      -4-

 
Common Stock until this Warrant shall have been exercised or converted in whole
or in part and the Warrant Stock purchasable upon such exercise shall have
become deliverable, as provided herein.

     7.  COMPANY'S RIGHT OF FIRST REFUSAL PRIOR TO WARRANT EXERCISE

     Before the Warrant may be sold or otherwise transferred by the Holder or
any transferee (including transfer by gift or operation of law), the Company or
its assignee(s) shall have a right of first refusal to purchase the Warrant on

Refusal").

          (a) Notice of Proposed Transfer.  The Holder shall deliver to the

              bona fide intention to sell or otherwise transfer the Warrant;
              (ii) the name of the proposed purchaser or other transferee
              ("Proposed Transferee"); and (iii) the bona fide cash price or
              other consideration for which the Holder proposes to transfer the
              Warrant (the "Offered Price"), and the Holder shall offer the
              Warrant at the Offered Price to the Company or its assignee(s),
              provided that any such assignee is a securityholder of the
              Company.

          (b) Exercise of Right of First Refusal.  At any time within 20 days

              the purchase price determined in accordance with subsection (c)
              below.

          (c) Purchase Price.  The purchase price ("Purchase Price") for the
              --------------                                                
              Warrant purchased by the Company or its assignee(s) under this
              Section shall be the Offered Price. If the Offered Price includes

              Board of Directors of the Company.

          (d) Payment.  Payment of the Purchase Price shall be made in cash (by

              check) within 15 days of the Company's written notice to the
              Holder pursuant to Section 7(b).

          (e) Holder's Right to Transfer.  If the Warrant proposed in the Notice
              --------------------------

              price, provided that such sale or other transfer is consummated
              within 90 days after the date of the Notice and provided further
              that any such sale or other transfer is effected in accordance
              with any applicable securities laws and the Proposed Transferee

              continue to apply to the Warrant in the hands of such Proposed
              Transferee. If the Warrant described in the Notice is not

              without the Company being offered the Right of First Refusal in
              the following transactions; provided that any Transferee shall
              agree to the terms of this Section 7 as to the Warrant:

              (1) A Holder's transfer of the Warrant in whole or in part to the
                  Company or to any shareholder of the Company.

                  employees are the beneficiaries) of such partnership.

              (5) A transfer by a Holder which is a corporation to any parent
                  company of the Holder, or any majority-owned subsidiary of
                  such parent company, provided that any such transferee does
                  not derive a majority of its revenues from products or
                  services that compete directly with products or services from
                  which the Company derives a majority of its revenues.

                  to any or all of its members or former members or any
                  professional employee (or entity of which such employees are
                  the beneficiaries) of such limited liability company.

     Any such transfer shall be made upon surrender of this Warrant together
with the Assignment Form attached hereto properly endorsed.

          (g) Termination of Right of First Refusal.  The Right of First Refusal
              -------------------------------------                             
              shall terminate (i) as to any Warrant Stock acquired upon the

              effective date of such exercise or conversion and (ii) as to any
              portion of the Warrant not previously exercised or converted, on

Company or the underwriters managing any underwritten offering of the Company's
securities, not to sell, make any short sale of, loan, pledge (or otherwise
encumber or hypothecate), grant any option for the purchase of, or otherwise

consent of the Company and such managing underwriters for such period of time,
not to exceed 180 days following the date of the Final Prospectus, as the Board
of Directors establishes pursuant to its good faith negotiations with such
managing underwriters; provided, however, that the Holder shall not be subject
to such market stand-off unless the officers and directors of the Company who
own stock of the Company shall also be bound by such restrictions. The Company
may impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such 180-day period.

     9.  EXCHANGE AND REGISTRY OF WARRANT

its terms, at such office or agency of the Company, and the Company shall be

     12.  ADJUSTMENTS

     The type and number of securities of the Company issuable upon exercise of
this Warrant and the Exercise Price are subject to adjustment as set forth
below:

          (a) If the Company shall at any time declare a dividend payable in
              shares of Common Stock, then the Warrantholder, upon exercise of
              this Warrant after the record date for the determination of
              holders of Common Stock entitled to receive such dividend, shall
              be entitled to receive upon exercise of this Warrant, in addition
              to the number of shares of Common Stock as to which this Warrant
              is exercised, such additional shares of Common Stock as such
              holder would have received had this Warrant been exercised
              immediately prior to such record date.

          (b) If the Company shall at any time effect a recapitalization or
              reclassification of such character that the shares of Common Stock
              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 of Common Stock which the Warrantholder shall be
              entitled to purchase upon exercise of this Warrant shall be
              increased or decreased, as the case may be, in direct proportion
              to the increase or decrease in the number of shares of Common
              Stock by reason of such recapitalization or reclassification, and
              the Exercise Price shall be, in the case of an increase in the
              number of shares, proportionately decreased and, in the case of a
              decrease in the number of shares, proportionately increased.

          (c) If the Company shall at any time distribute to holders of Common
              Stock cash, evidences of indebtedness or other securities or
              assets (other than cash dividends or distributions payable out of
              earned surplus) then, in any such case, the Warrantholder shall be
              entitled to receive, upon exercise of this Warrant, with respect
              to each share of Common Stock issuable upon such exercise, the
              amount of cash or evidences of indebtedness or other securities or
              assets which such holder would have been entitled to receive with
              respect to each such share of Common Stock as a result of the
              happening of such event had this Warrant been exercised
              immediately prior to the record date or other date fixing
              stockholders to be affected by such event.

          (d) If at any time on or after the date hereof the Company shall
              subdivide its outstanding shares of Common Stock into a greater
              number of shares, the Warrant Price in effect immediately prior to
              such subdivision shall thereby be proportionately reduced and the
              number of shares receivable upon exercise of the Warrant shall
              thereby be proportionately increased; and, conversely, if at any
              time on or after the date hereof the outstanding number of shares
              of Common Stock shall be combined into a smaller number of shares,
              the Warrant Price in effect immediately prior to such combination
              shall thereby be proportionately increased 

                                      -8-

 
              and the number of shares receivable upon exercise of the Warrant
              shall thereby be proportionately decreased.

          (e) As used in this Warrant the term "Exercise Price" shall mean the
              purchase price per share specified in this Warrant until the
              occurrence of an event stated in subsections (b) or (d) of this
              Section 12 and thereafter shall mean said price as adjusted from
              time to time in accordance with the provisions of said
              subsections. No adjustment made pursuant to any provision of this
              Section 12 shall have the effect of increasing the total
              consideration payable upon exercise of this Warrant in respect of
              all the Common Stock as to which this Warrant may be exercised.

          (f) In the event that at any time, as a result of an adjustment made
              pursuant to this Section 12, the Warrantholder shall, upon
              exercise of this Warrant, become entitled to receive shares and/or
              other securities or assets (other than Common Stock) then,
              wherever appropriate, all references herein to shares of Common
              Stock shall be deemed to refer to and include such shares and/or
              other securities or assets; and thereafter the number of such
              shares and/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 Section 12.

          (g) In case of any adjustment in the Exercise Price or number and type
              of securities issuable on the exercise of this Warrant, the
              Company will promptly give written notice thereof to the Holder in
              the form of a certificate, confirmed by an officer of the Company,
              setting forth such adjustment and showing in reasonable detail the
              facts upon which adjustment is based.

     13.  NOTICES OF RECORD DATE, ETC.

     In the event of:

          (a) any taking by the Company of a record of the holders of Warrant
              Stock or securities into which the Warrant Stock is convertible
              for the purpose of determining the holders thereof who are
              entitled to receive any dividend or other distribution,

          (b) any capital reorganization of the Company, any reclassification or
              recapitalization of the capital stock of the Company, or any
              transfer of all or substantially all the assets of the Company to,
              or consolidation or merger of, the Company with or into any
              person,

          (c) any voluntary or involuntary dissolution, liquidation or winding-
              up of the Company,

                                      -9-

 
          (d) a sale of substantially all of the outstanding capital stock of
              the Company or the issuance of new shares representing the
              majority of the Company's right to vote, or

          (e) the consummation of any Qualified IPO of the Company's Common
              Stock,

then and in each such event the Company will mail to the Holder a notice
specifying the record date for voting or the date of closing , as applicable, of
any event (a)-(e) above.  Such notice shall be delivered to the Holder at least
fifteen (15) days prior to the actual or proposed date of consummation of the
relevant event.
