     2.  Manner of Exercise; Issuance of Certificates; Payment for Shares; No
         --------------------------------------------------------------------
Fractional Shares.  The rights represented by this Warrant may be exercised by
-----------------
the holder hereof, in whole or in part, by the surrender of this Warrant,
together with a completed Exercise Agreement in the form attached hereto
("Exercise Agreement"), during normal business hours on any business day at the
principal office of the Company (or such other office or agency of the Company
as it may designate by notice in writing to the holder hereof at the address of
such holder appearing on the books of the Company) at any time during the period
set forth in paragraph 3 hereof and upon payment to the Company by certified
check or bank draft in an amount equal to the Exercise Price for the Warrant
Shares to be purchased in connection with such exercise.  The Company agrees
that the shares so purchased shall be and are deemed to be issued to the holder
hereof or its designee (subject to the transfer restrictions applicable to this
Warrant and to shares purchased upon exercise of this Warrant) as the record
owner of such shares as of the close of business on the date on which this
Warrant shall have been surrendered and payment made for such shares as
aforesaid.

     Certificates for the Warrant Shares so purchased, representing the
aggregate number of shares specified in said Exercise Agreement, shall be
delivered to the holder hereof within a reasonable time, not exceeding five (5)
business days, after the rights represented by this Warrant shall have been so
exercised.  The stock certificate or certificates so delivered shall be in such
denominations as may be requested by the holder hereof and shall be registered
in the name of said holder or such other name as shall be designated by said
holder (subject to the transfer restrictions applicable to this Warrant and to
shares purchased upon exercise of this Warrant).  If this Warrant shall have
been exercised only in part, then, unless this Warrant has expired, the Company
shall, at its expense, at the time of delivery of said stock certificate(s),
deliver to said

                                      -2-
<PAGE>

holder a new Warrant representing the right to purchase the number of shares of
Common Stock with respect to which this Warrant shall not then have been
exercised. The Company shall pay all taxes and other expenses and charges
payable in connection with the preparation, execution and delivery of stock
certificates (and any new Warrants) pursuant to this paragraph 2 except that, in
case such stock certificates shall be registered in a name or names other than
the holder of this Warrant or such holder's nominee, funds sufficient to pay all
stock transfer taxes which shall be payable in connection with the execution and
delivery of such stock certificates shall be paid by the holder hereof to the
Company at the time of the delivery of such stock certificates by the Company as
mentioned above.

     The holder of this Warrant may exercise this Warrant by surrendering it to
the Company to purchase a number of shares of Common Stock equal to the number
of such shares then purchasable upon exercise hereof less the number of such
shares equal to the quotient of the aggregate exercise price of all such shares
underlying this Warrant divided by the Fair Market Price per Share.  Fair Market
Price per Share shall mean the average of the closing sales prices, if
available, or the average of the bid and asked prices for the Common Stock (or
its successor), on the principal market therefor for the five trading days
preceding the day which is two business days prior to the day of exercise, or if
no such price is available, as determined by the Board of Directors of the
Company.

     This Warrant shall be exercisable only for a whole number of Warrant Shares
unless this Warrant is being exercised in full.  No fractions of shares of
Common Stock, or scrip for any such fractions of shares, shall be issued upon
the exercise of this Warrant.  Instead, the Company shall pay a cash adjustment
in respect of such fractional interest in an amount equal to the fair market
value of such fractional interest as determined by the Company's Board of
Directors.

     3.  Period of Exercise.  This Warrant is exercisable at any time or from
         ------------------
time to time during the period from the date of issue hereof until the date five
years from the date hereof.

     4.  Shares to be Fully Paid; Reservation of Shares.  The Company covenants
         ----------------------------------------------
and agrees that all Warrant Shares will be duly authorized and validly issued
and, upon issuance in accordance with the terms and conditions hereof, will be
fully paid and nonassessable and free from all taxes, liens and charges with
respect to the issue thereof.  Without limiting the generality of the foregoing,
the Company covenants and agrees that it will from time to time take all such
action as may be requisite to assure that the par value per Warrant Share is at
all times equal to or less than the Exercise Price then in effect.  The Company
further covenants and agrees that, during the period within which the rights
represented by this Warrant may be exercised, the Company will at all times have
authorized, and reserved for the purpose of issue upon exercise of the
subscription rights evidenced by this Warrant, a sufficient number of shares of
Common Stock to provide for the exercise of the rights represented by this
Warrant and the other Warrants, if any.

     5.  Anti-dilution Provisions.  The number, rights and privileges of the
         ------------------------
shares of Common Stock issuable upon exercise of this Warrant shall be subject
to the following adjustments:

                                      -3-
<PAGE>

          (a) Adjustment for Change in Capital Stock.  In case the Company shall
              --------------------------------------
     at any time after the date of this Warrant (i) pay a dividend or make a
     distribution on the outstanding Common Stock payable in shares of Common
     Stock or other shares of its capital stock, (ii) subdivide the outstanding
     Common Stock into a greater number of shares, (iii) combine the outstanding
     Common Stock into a smaller number of shares, or (iv) issue any shares of
     its capital stock by reclassification of the Common Stock (including any
     such reclassification in connection with a consolidation or merger in which
     the Company is the continuing corporation), then, in each case, the
     exercise rights of the holder hereof, in effect immediately prior to such
     action shall be adjusted so that the holder of this Warrant thereafter
     converted may receive the number of shares of Common Stock of the Company
     which such holder would have owned immediately following such action if
     such holder had converted this Warrant immediately prior to such action.
     The adjustment shall become effective immediately after the record date in
     the case of a dividend or distribution and immediately after the effective
     date in the case of a subdivision, combination or reclassification.  Such
     adjustment shall be made successively whenever any event listed above shall
     occur.

          (b) Notice of Adjustment.  Whenever there shall be an adjustment as
              --------------------
     provided in this Section 5, the Company shall promptly cause written notice
     thereof to be sent by registered mail, postage prepaid, to the holder, at
     its address on the records of the Company, which notice shall be
     accompanied by an officer's certificate setting forth the nature of such
     adjustment and setting forth a brief statement of the facts requiring such
     adjustment and the computation thereof, which officer's certificate shall
     be conclusive evidence of the correctness of any such adjustment absent
     manifest error.

          (c) Consolidation; Merger; Reclassification.
              ---------------------------------------

               (i) In case of any consolidation with or merger of the Company
          with or into another corporation (other than a merger or consolidation
          in which the Company is the surviving or continuing corporation), or
          in case of any sale, lease, or conveyance to another corporation of
          the property and assets of any nature of the Company as an entirety or
          substantially as an entirety, such successor, leasing, or purchasing
          corporation, as the case may be, shall (x) execute with the holder an
          agreement providing that the holder shall have the right thereafter to
          receive upon exercise of this Warrant solely the kind and amount of
          shares of stock and other securities, property, cash, or any
          combination thereof receivable upon such consolidation, merger, sale,
          lease, or conveyance by a holder of the number of shares of Common
          Stock into which this Warrant might have been exercised immediately
          prior to such consolidation, merger, sale, lease, or conveyance and
          (y) make effective provision in its certificate of incorporation or
          otherwise, if necessary, to effect such agreement.  Such agreement
          shall provide for adjustments which shall be as nearly equivalent as
          practicable to the adjustments in this Section 5.

                                      -4-
<PAGE>

               (ii) In case of any reclassification or change of the shares of
          Common Stock issuable upon exercise of this Warrant (other than a
          change in par value or from no par value to a specified par value, or
          as a result of a subdivision or combination, but including any change
          in the shares into two or more classes or series of shares), or in
          case of any consolidation or merger of another corporation into the
          Company in which the Company is the continuing corporation and in
          which there is a reclassification or change (including a change to the
          right to receive cash or other property) of the shares of Common Stock
          (other than a change in par value, or from no par value to a specified
          par value, or as a result of a subdivision or combination, but
          including any change in the shares into two or more classes or series
          of shares), the holder shall have the right thereafter to receive upon
          exercise of this Warrant solely the kind and amount of shares of stock
          and other securities, property, cash, or any combination thereof
          receivable upon such reclassification, change, consolidation, or
          merger by a holder of the number of shares of Common Stock into which
          this Warrant might have been exercised immediately prior to such
          reclassification, change, consolidation, or merger.  Thereafter,
          appropriate provision shall be made for adjustments which shall be as
          nearly equivalent as practicable to the adjustments in Section 5(a)
          above.

               (iii)  The above provisions of this Section 5(c) shall similarly
          apply to successive reclassifications and changes of shares of Common
          Stock and to successive consolidations, mergers, sales, leases, or
          conveyances.

          (d) Notice of Certain Transactions.  In case at any time the Company
              ------------------------------
     shall propose

               (i) to pay any dividend or make any distribution on shares of
          Common Stock in shares of Common Stock or make any other distribution
          to all holders of Common Stock;

               (ii) to issue any rights, warrants, or other securities to all
          holders of Common Stock entitling them to purchase any additional
          shares of Common Stock or any other rights, warrants, or other
          securities; or

               (iii)  to effect any reclassification or change of outstanding
          shares of Common Stock, or any consolidation, merger, sale, lease, or
          conveyance of property, described in Section 5(c); or

               (iv) to effect any liquidation, dissolution, or winding-up of the
          Company; or

               (v) to take any other action which would cause an adjustment to
          the Exercise Price;

                                      -5-
<PAGE>

     then, and in any one or more of such cases, the Company shall give written
     notice thereof, by registered mail, postage prepaid, to the holder at the
     holder's address as it shall appear in the records of the Company mailed at
     least 15 days prior to (i) the date as of which the holders of record of
     shares of Common Stock to be entitled to receive any such dividend,
     distribution, rights, warrants, or other securities are to be determined,
     (ii) the date on which any such reclassification, change of outstanding
     shares of Common Stock, consolidation, merger, sale, lease, conveyance of
     property, liquidation, dissolution, or winding-up is expected to become
     effective, and the date as of which it is expected that holders of record
     of shares of Common Stock shall be entitled to exchange their shares for
     securities or other property, if any, deliverable upon such
     reclassification, change of outstanding shares, consolidation, merger,
     sale, lease, conveyance of property, liquidation, dissolution, or winding-
     up, or (iii) the date of such action which would require an adjustment to
     the Exercise Price.

     6.  Certain Agreements of the Company.  The Company covenants and agrees
         ---------------------------------
that:

          (a) Certain Actions Prohibited.  The Company will not, by amendment of
              --------------------------
     its Certificate of Incorporation or through any reorganization, transfer of

     any other voluntary action, avoid or seek to avoid the observance or
     performance of any of the terms to be observed or performed hereunder by
     the Company, but will at all times in good faith assist in the carrying out
     of all the provisions of this Warrant and in the taking of all such action
     as may reasonably be requested by the holder of any Warrant in order to
     protect the exercise privilege of the holders of the Warrants against
     dilution or other impairment, consistent with the tenor and purpose of this
     Warrant.

          (b) Successors and Assigns.  This Warrant will be binding upon any

name other than that of the holder of the Warrant exercised.

     8.  Closing of Books.  The Company will at no time close its transfer books

entitle the holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provision of this Warrant, in the absence of affirmative
action by the holder hereof to purchase Warrant Shares, and no mere enumeration

                                      -6-
<PAGE>

any liability of such holder for the Exercise Price or as a stockholder of the

     subscribe for and purchase the number of shares of Common Stock which may
     be subscribed for and purchased hereunder, each of such new Warrants to

     statement under the Securities Act, each certificate for Warrant Shares
     initially issued upon the exercise of this Warrant and each certificate for
     shares of capital stock of the Company issued to any subsequent transferee
     of any such certificate shall bear the following legend:
