      2.    Exercise of Warrant.

            (a)    This Warrant may be exercised during the Exercise Period in
      accordance with the vesting schedule set forth on Schedule A attached
      hereto, by the Holder by the surrender of this Warrant (with the
      subscription duly executed) at the address set forth in paragraph 11(a)
      hereof, together with proper payment of the Exercise Price.
      Notwithstanding the foregoing, this Warrant shall become fully vested and
      immediately exercisable in the event of: (i) a Merger Triggering Event; or
      (ii) upon the breach of any covenant or obligation in this Warrant, the
      Stock Purchase Agreement or the Registration Rights Agreement if such
      breach is not cured within 30 days of notice of such breach delivered to
      the Company. Payment for the Warrant Shares to be purchased shall be made
      by wire transfer or certified or official bank check payable to the order
      of the Company. If this Warrant is exercised in part, this Warrant must be
      exercised for a whole number of shares of Common Stock, and the Holder is
      entitled to receive a new Warrant covering the number of Warrant Shares in
      respect of which this Warrant has not been exercised. Upon such surrender
      of this Warrant, the Company will issue a certificate or certificates in
      the name of the Holder for the number of shares of Common Stock to which
      the Holder shall be entitled. The Company shall not be required to issue a
      fractional share of Common Stock upon any exercise of this Warrant, but
      the Company shall pay an amount in cash equal to the Current Market Price
      for one Warrant Share on the date the Warrant is exercised, multiplied by
      the fraction of a Warrant Share that would be issuable on the exercise of
      this Warrant.

            (b)    In the event any Holder elects upon exercise to surrender
      this Warrant for payment of the applicable Exercise Price for the shares
      being purchased, this Warrant shall be surrendered and canceled. To the
      extent any Holder elects to pay all or part of the Exercise Price by
      surrendering this Warrant to the Company, the number of purchasable shares
      under this Warrant required to be surrendered as payment for the Exercise
      Price (the "Warrant Consideration Amount") shall be equal to that number
      obtained by dividing (i) that amount of the aggregate Exercise Price that
      any Holder elects by written notice to the Company to pay by the
      application of this Warrant (such notice setting forth, in addition, the
      required reduction in the number of shares purchasable by this Warrant as
      calculated and shown in sufficient detail in accordance with the
      immediately succeeding clause), by (ii) the Exercise Price per share on
      the date of exercise.

            (c)    In the event of any exercise of the rights represented by
      this Warrant, (i) certificates for the shares of Warrant Shares so
      purchased shall be dated the date of such exercise and delivered to the
      Holder hereof within a reasonable time, not exceeding five Business Days
      after such exercise, and the Holder hereof shall be deemed for all


                                     - 4 -
<PAGE>   5

      purposes to be the Holder of the shares of Warrant Shares so purchased as
      of the date of such exercise, and (ii) unless this Warrant has expired, a
      new Warrant representing the number of shares equal to (A) the number of
      shares purchasable under this Warrant less (B) the sum of (1) the number
      of shares of Warrant Shares purchased upon exercise and (2) the Warrant
      Consideration Amount, if any, shall be issued to the Holder hereof within
      such time.

      3.    Certain Adjustments. The Exercise Price and the kind and number of
shares of Common Stock issuable upon exercise of this Warrant shall be subject
to adjustment as set forth below in this paragraph 3. The Company shall give the
registered Holder notice of any event described below which requires an
adjustment pursuant to this paragraph 3 in accordance with the provisions of
paragraph 4.

            (a)    Stock Dividends, Subdivisions and Combinations. If at any
      time the Company shall:

                   (i)    fix a record date for the purpose of determining the
            holders of its Common Stock entitled to receive a dividend payable
            in, or other distribution of, additional shares of Common Stock;

                   (ii)   subdivide its outstanding shares of Common Stock into
            a larger number of shares of Common Stock;

                   (iii)  combine its outstanding shares of Common Stock into a
            smaller number of shares of Common Stock; or

                   (iv)   issue any shares of its capital stock or other
            securities by reclassification of the Common Stock (other than
            pursuant to paragraph 3(c) below); then the Exercise Price shall be
            proportionately decreased in the case of such a dividend or
            distribution of additional shares of Common Stock or such a
            subdivision, or proportionately increased in the case of such a
            combination, or the kind of capital stock or other securities of the
            Company which may be purchased shall be adjusted in the case of such
            a reclassification of the Common Stock, each on the record date for
            such dividend or distribution or effective date of such subdivision,
            combination or reclassification, as the case may be, such that the
            Holder shall be entitled to receive, upon exercise of this Warrant,
            the aggregate number and kind of shares of Common Stock which, if
            this Warrant had been fully exercised immediately prior to such
            date, it would have owned upon such exercise and been entitled to
            receive by virtue of such dividend, distribution, subdivision,
            combination or reclassification.

            (b)    Certain Other Dividends and Distributions. If at any time the
      Company shall fix a record date for the purpose of determining the holders
      of its Common Stock entitled to receive any dividend or other distribution
      (including any such distribution made in connection with a consolidation
      or merger, but excluding any distribution referred to in subparagraph (a)
      above) of:



                                     - 5 -
<PAGE>   6

                  (i)    any evidences of indebtedness, any shares of its
            capital stock (including Convertible Securities but excluding Common
            Stock) or any other securities or property of any nature whatsoever
            (including cash but excluding normal cash dividends or cash
            distributions permitted under applicable law so long as in each case
            such cash is payable solely out of earnings or earned surplus of the
            Company); or

                  (ii)   any warrants or other rights to subscribe for or
            purchase any evidences of its indebtedness, any shares of its
            capital stock (including Convertible Securities) or any other of its
            securities or its property of any nature whatsoever;

            then the Exercise Price shall be adjusted to equal the Exercise
            Price in effect prior to such distribution or dividend multiplied by
            a fraction, (A) the numerator of which shall be (1) the Current
            Market Price per share of the Common Stock on such record date minus
            (2) the amount allocable to one share of Common Stock of the fair
            value of any and all such evidences of indebtedness, shares of
            stock, other securities or property or warrants or other
            subscription or purchase rights so distributable (as determined in
            good faith by the Board of Directors of the Company and, unless
            waived by the Holder, supported by an opinion from an investment
            banking firm of nationally recognized standing approved by the
            Holder, which approval shall not be unreasonably withheld), and (B)
            the denominator of which shall be such Current Market Price per
            share of Common Stock on such record date. Such adjustments shall be
            made whenever such a record date is fixed. A reclassification of the
            Common Stock (other than a change in par value, or from par value to
            no par value or from no par value to par value) into shares of
            Common Stock and shares of any other class of stock shall be deemed
            a distribution by the Company to the holders of its Common Stock of
            such shares of such other class of stock within the meaning of this
            subparagraph (b) and, if the outstanding shares of Common Stock
            shall be changed into a larger or smaller number of shares of Common
            Stock as a part of such reclassification, such change shall be
            deemed a subdivision or combination, as the case may be, of the
            outstanding shares of Common Stock within the meaning of
            subparagraph (a). The Company shall give to the Holder of this
            Warrant not less than twenty (20) days' prior notice of any record
            date referred to in this subparagraph (b) in accordance with the
            provisions of paragraph 4.

            (c)    Adjustments for Consolidation, Merger, Sale of Assets,
      Reorganization, etc.

                  (i)    In case the Company after the date hereof (A) shall
            consolidate with or merge into any other Person and shall not be the
            continuing or surviving corporation of such consolidation or merger,
            or (B) shall permit any other Person to consolidate with or merge
            into the Company and the Company shall be the continuing or
            surviving Person but, in connection with such consolidation or



                                     - 6 -
<PAGE>   7
            merger, the Common Stock shall be changed into or exchanged for
            stock or other securities of any other Person or cash or any other
            property, or (C) shall transfer all or substantially all of its
            properties or assets to any other Person or (D) shall effect a
            capital reorganization or reclassification of the Common Stock
            (other than a capital reorganization or reclassification for which
            adjustment in the Exercise Price is provided in subparagraph 3(a) or
            subparagraph 3(b)), then, and in the case of each such transaction,
            proper provision shall be made so that, upon the basis and the terms
            and in the manner provided in this Warrant, the Holder of this
            Warrant shall be entitled (x) upon the exercise hereof at any time
            after the consummation of such transaction, to the extent this
            Warrant is not exercised prior to such transaction, or is redeemed
            in connection with such transaction, to receive at the Exercise
            Price in effect at the time immediately prior to the consummation of
            such transaction in lieu of the Common Stock issuable upon such
            exercise of this Warrant prior to such transaction the stock and
            other securities, cash and property to which such Holder would have
            been entitled upon the consummation of such transaction if such
            Holder had exercised the rights represented by this Warrant
            immediately prior thereto, subject to adjustments (subsequent to
            such corporate action) as nearly equivalent as possible to the
            adjustments provided for in this paragraph 3 or (y) to sell this
            Warrant (or, at such Holder's election, a portion thereof) to the
            Person continuing after or surviving such event specified in clauses
            (A) through (D) above, or to the Company (if the Company is the
            continuing or surviving Person) at a sales price equal to the amount
            of cash, property and/or the number of shares of Common Stock or
            other securities to which a holder of the number of shares of Common
            Stock which would otherwise have been delivered upon the exercise of
            this Warrant or the portion hereof redeemed would have been entitled
            upon the effective date or closing of any such event specified in
            clauses (A) through (D) above (the "Event Consideration"), less the
            amount or portion of such Event Consideration having a fair value
            equal to the aggregate Exercise Price applicable to this Warrant or
            the portion hereof so sold.

                  (ii)    Notwithstanding anything contained in this Warrant to
            the contrary, the Company will not effect any of the transactions
            described in clauses (A) through (D) of the above subparagraph (i)
            unless, prior to the consummation thereof, the surviving Person (if
            other than the Company) in any merger or consolidation described in
            such clauses, each Person which is to acquire the Company's assets
            in any transaction described in clause (c) above, and each Person
            (other than the Company) which may be required to deliver any stock,
            securities, cash or property upon the exercise of this Warrant as
            provided herein, shall assume, by written instrument delivered to,
            and reasonably satisfactory to, the Holder of this Warrant, (A) the
            obligations of the Company under this Warrant (and if the Company
            shall survive the consummation of such transaction, such assumption
            shall be in addition to, and, if requested by the Holder, shall not
            release the Company from, any continuing obligations of the Company
            under this Warrant) and (B) the obligation to deliver to such Holder
            such shares of stock, securities, cash or, property as, in
            accordance with the foregoing provisions of this paragraph (c), such




                                     - 7 -
<PAGE>   8
            Holder shall be entitled to receive, and such Person shall have
            similarly delivered to such Holder an opinion of counsel for such
            Person, which counsel shall be reasonably satisfactory to such
            Holder, stating that this Warrant shall thereafter continue in full
            force and effect and the terms hereof (including, without
            limitation, all of the provisions of this paragraph 3) shall be
            applicable to the stock, securities, cash or property which such
            Person may be required to deliver upon any exercise of this Warrant
            or the exercise of any rights pursuant hereto.

                  (iii)    In case any of the transactions described in clauses
            (A) through (D) of subparagraph (i) shall be proposed to be effected
            (any such transaction a "Merger Triggering Event"), the Holder of
            this Warrant may, and the Company agrees that as a condition to the
            consummation of any such Merger Triggering Event, the Company shall
            secure the right of such Holder to, sell this Warrant (or, at such
            Holder's election, a portion thereof) to the Person continuing after
            or surviving such Merger Triggering Event, or the Company (if the
            Company is the continuing or surviving Person), simultaneously with,
            the effective date or closing of such Merger Triggering Event, at a
            sale price equal to the amount of cash, property and/or the number
            of shares of Common Stock or other securities to which a holder of
            the number of shares of Common Stock which would otherwise have been
            deliverable upon the exercise of this Warrant or the portion hereof
            redeemed would have been entitled upon the effective date or closing
            of such Merger Triggering Event (the "Transaction Consideration"),
            less the amount or portion of such Transaction Consideration having
            a fair value equal to the aggregate Exercise Price applicable to
            this Warrant or the portion hereof so sold. In the event that the
            Holder of this Warrant exercises its rights under this subparagraph
            (iii) to sell this Warrant (or a portion thereof) simultaneously
            with the effective date or closing of any such Merger Triggering
            Event, the Company shall not effect any such Merger Triggering Event
            unless upon or prior to the consummation thereof such amounts of
            cash, property, Common Stock, or other securities are delivered to
            the Holder of this Warrant. Not less than twenty (20) days' prior
            notice of any Merger Triggering Event shall be given to the Holder
            of this Warrant in accordance with paragraph 4.

            (d)    Adjustment of Number of Warrant Shares. Upon each adjustment
      of the Exercise Price, as the case may be, pursuant to subparagraph (a) or
      (b) of this paragraph 3, this Warrant shall be deemed to evidence the
      right to purchase, at the adjusted Exercise Price, that number of shares
      of Common Stock obtained by multiplying the number of shares of Common
      Stock covered by this Warrant immediately prior to such adjustment by the
      Exercise Price in effect prior to such adjustment and dividing the product
      so obtained by the Exercise Price in effect after such adjustment. If the
      Company shall be in default under any provision of this Warrant so that
      shares issued at the Exercise Price adjusted in accordance with the terms
      of this Warrant would not be validly issued, the adjustment of number of
      shares provided for in the foregoing sentence shall nonetheless be made,
      and the Holder of this Warrant shall be entitled to purchase such greater
      number of shares at the lowest price at which such shares may then be
      validly issued under



                                     - 8 -
<PAGE>   9

      applicable law. Such exercise shall not constitute a waiver of any claim
      arising against the Company by reason of its default under this Warrant.

            (e)   When Adjustments to Be Made. No adjustment in the Exercise
      Price shall be required by this paragraph 3 if such adjustment either by
      itself or with other adjustments not previously made would require an
      increase or decrease of less than 1% in such price. Any adjustment
      representing a change of less than such minimum amount which is postponed
      shall be carried forward and made as soon as such adjustment, together
      with other adjustments required by this paragraph 3 and not previously
      made, would result in a minimum adjustment. Notwithstanding the foregoing,
      any adjustment carried forward shall be made no later than ten Business
      Days prior to the Termination Date. All calculations under this
      subparagraph (e) shall be made to the nearest cent. For the purpose of any
      adjustment, any specified event shall be deemed to have occurred at the
      close of business on the date of its occurrence.

            (f)    Fractional Interests. In computing adjustments under this
      paragraph 3, fractional interests in Common Stock shall be taken into
      account to the nearest whole share.

            (g)    When Adjustments Not Required. If the Company shall fix a
      record date for the purpose of determining the holders of its Common Stock
      entitled to receive a dividend or distribution and shall, thereafter and
      before the distribution to stockholders thereof, legally abandon its plan
      to pay or deliver such dividend or distribution, then thereafter no
      adjustment shall be required by reason of the taking of such record and
      any such adjustment previously made in respect thereof shall be rescinded
      and annulled.

            (h)    Certain Limitations. Subject to the provisions of paragraph
      6, there shall be no adjustment of the Exercise Price hereunder to the
      extent that such adjustment would cause the Exercise Price to be less than
      the par value per share of the Common Stock, which par value shall not at
      any time while this Warrant is outstanding exceed $.01.

            (i)    Other Action Affecting Common Stock. In case after the date
      hereof the Company shall take any action affecting its Common Stock, other
      than an action described in any of the foregoing subparagraphs (a) through
      (h) of this paragraph 3, inclusive, and the failure to make any adjustment
      would not fairly protect the purchase rights represented by this Warrant
      in accordance with the essential intent and principle of this paragraph 3,
      then the Exercise Price and/or the number of Warrant Shares shall be
      adjusted in such manner and at such time as the Board of Directors of the
      Company may in good faith determine to be equitable in the circumstances.

      4.    Notices.

            (a)    Notices of Adjustments. Whenever the Exercise Price or the
      number of Warrant Shares shall be adjusted pursuant to paragraph 3, the
      Company shall forthwith deliver to the Holder a certificate prepared by
      the Company, setting forth, in reasonable detail, the event requiring the
      adjustment and the method by which such adjustment was



                                     - 9 -
<PAGE>   10

      calculated (including a description of the basis on which the Board of
      Directors of the Company determined the fair value of any evidences of
      indebtedness, shares of stock, other securities or property or warrants or
      other subscription or purchase rights), specifying the number of Warrant
      Shares then issuable hereunder, the Exercise Price after giving effect to
      such adjustment and (to the extent applicable) describing the number and
      kind of any other shares of stock for which the Warrant is exercisable. In
      the event that the Holder shall disagree with any such adjustment or with
      the terms of any new agreement to be entered into pursuant to paragraph
      3(c), it shall notify the Company thereof and any disagreement shall be
      resolved by an investment banking firm of nationally recognized standing
      mutually agreeable to the Company and the Holder, or if the Company and
      the Holder are unable to agree upon an investment banking firm, an
      investment banking firm selected by an investment banking firm chosen by
      the Company and an investment banking firm chosen by the Holder.

            (b)    Notices of Corporate Action. In the event of any of the
      following:

                   (i)    any taking by the Company of a record of the holders
            of any class of securities for the purpose of determining the
            holders thereof who are entitled to receive any dividend or other
            distribution, or any right to subscribe for, purchase or otherwise
            acquire any shares of stock of any class or any other securities or
            property, or to receive any other right, which dividend,
            distribution or other right affects the rights of the Holder, or

                   (ii)   any capital reorganization of the Company, any
            reclassification or recapitalization of the capital stock of the
            Company or any consolidation or merger involving the Company and any
            other party or any transfer of all or substantially all the assets
            of the Company to any other party, or

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

The Company will mail to the Holder a notice specifying (A) the date or expected
date on which any such record is to be taken for the purpose of such dividend,
distribution or right and the amount and character of any such dividend,
distribution or right and (B) the date or expected date on which any such
reorganization, reclassification, recapitalization, consolidation, merger,
transfer, dissolution, liquidation or winding-up is to take place and the time,
if any such time is to be fixed, as of which the holders of record of Common
Stock (or other securities) shall be entitled to exchange their shares of Common
Stock (or other securities) for the securities or other property deliverable
upon such reorganization, reclassification, recapitalization, consolidation,
merger, transfer, dissolution, liquidation or winding-up. Such notice shall be
mailed at least twenty (20) days prior to the date herein specified, in the case
of any date referred to in the foregoing subdivision (A), and at least twenty
(20) days prior to the date therein specified, in the case of the date referred
to in the foregoing subdivision (B).

      5.    Reservation of Warrant Shares. The Company agrees that, upon
commencement of the Exercise Period and at all times prior to the Termination
Date, the Company will at all



                                     - 10 -
<PAGE>   11

times have authorized and in reserve, and will keep available, solely for
issuance or delivery upon the exercise of this Warrant, the shares of the Common
Stock and other securities and properties as from time to time shall be
receivable upon the exercise of this Warrant, free and clear of all restrictions
on sale or transfer and free and clear of all preemptive rights. The Company
shall not by any action, including, without limitation, amending its certificate
of incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities 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 actions as may be
necessary or appropriate to protect the rights of the Holders hereof against
impairment. Without limiting the generality of the foregoing, the Company will
(a) not increase the par value of any shares of Common Stock receivable upon the
exercise of this Warrant above the amount payable therefor upon such exercise
immediately prior to such increase in par value, (b) take all such action as may
be necessary or appropriate in order that the Company may validly and legally
issue fully paid and nonassessable shares of Common Stock, free and clear of any
liens, claims, encumbrances and restrictions (other than as provided herein)
upon the exercise of this Warrant, and (c) use its best efforts to obtain all
such authorizations, exemptions or consents from any public regulatory body
having jurisdiction thereof as may be necessary to enable the Company to perform
its obligations under this Warrant.

      6.    Fully Paid Stock; Taxes. The shares of Common Stock represented by
each and every certificate for Warrant Shares delivered on the exercise of this
Warrant and the payment of the Exercise Price set forth herein shall, at the
time of such delivery, be validly issued and outstanding, fully paid and
nonassessable, and not subject to preemptive rights, and the Company will take
all such actions as may be necessary to assure that the par value or stated
value, if any, per share of the Common Stock is at all times equal to or less
than the then Exercise Price. If the Exercise Price is at any time less than the
par value of the Warrant Shares or if the Warrant at any time is exercisable by
its delivery alone and without payment of any additional consideration, the
Company also covenants and agrees to cause to be taken such action (whether by
decreasing the par value of the Warrant Shares, the conversion of the Warrant
Shares from par value to no par value, or otherwise) as will permit the exercise
of this Warrant without any additional payment by the Holder hereof (other than
payment of the Exercise Price, if any, and applicable transfer taxes, if any)
and the issuance of the Warrant Shares, which Warrant Shares, upon such
issuance, will be fully paid and non-assessable. The Company further covenants
and agrees that it will pay, when due and payable, any and all federal and state
stamp, original issue or similar taxes which may be payable in respect of the
issuance of any Warrant Shares or certificate therefor and that the Warrant
Shares will be otherwise free from all taxes, liens and charges with respect to
issuance.

      7.    Transferability. Upon execution and delivery of an assignment
instrument substantially in the form attached hereto, an assignee shall be a
party to this Agreement and shall have the rights and obligations of the Holder,
to the extent of such assignment, and the Holder shall be released from its
obligations hereunder to a corresponding extent. Upon the consummation of any
assignment permitted pursuant to this paragraph, the Holder and the Company
shall make appropriate arrangements, so that, if required, new Warrants shall be
issued



                                     - 11 -
<PAGE>   12

to the Holder and the assignee. The Holder shall give the Company prior written
notice of the date that any such assignment shall become effective, which date
shall be no less than ten days after the date such notice is given.

      8.    Loss, etc., of Warrant. Upon receipt of evidence satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant, and of
indemnity or bond reasonably satisfactory to the Company, if lost, stolen or
destroyed, and upon surrender and cancellation of this Warrant, if mutilated,
the Company shall execute and deliver to the Holder a new Warrant of the like
date, tenor and denomination.

      9.    Holder Not Shareholder. This Warrant does not confer upon the Holder
any right to vote or to consent to or receive notice as a shareholder of the
Company, as such, in respect of any matters whatsoever, or any other rights or
liabilities as a shareholder, prior to the exercise hereof.

      10.   Surrender. The Holder may at any time surrender all or a portion of
this Warrant for cancellation by transmitting same to the Company at its address
set forth herein accompanied by a written notice setting forth the Holder's
intention to surrender this Warrant (or such portion) for cancellation and upon
such transmittal by the Holder, this Warrant (or such portion) shall become null
and void and of no further force and effect.

      11.   Notices. Any notice, demand, request, consent, approval,
declaration, delivery or other communication hereunder to be made pursuant to
the provisions of this Warrant shall be sufficiently given or made if in writing

      12.   Miscellaneous.

            (a)    Remedies. The Company agrees that monetary damages would not
      be adequate compensation for any loss incurred by reason of a breach by it
      of the provisions of this Warrant and hereby agrees to waive the defense
      in any action for specific performance that a remedy at law would be
      adequate. Accordingly, it is agreed that the Holder shall be entitled to
      an injunction, restraining order or other equitable relief to prevent
      breaches of this Agreement and to enforce specifically the terms and
      provisions hereof in any court of competent jurisdiction in the United
      States or any state thereof. Such remedies shall be cumulative and
      nonexclusive and shall be in addition to any other rights and remedies the
      parties may have under this Agreement.

            (b)    No Inconsistent Agreements. The Company will not on or after
      the date of this Warrant enter into any agreement with respect to its
      securities which is inconsistent with the rights granted to the Holder in
      this Warrant, otherwise conflicts with the provisions hereof or would be
      violated by the performance of the Company's obligations hereunder. The
      Company represents and warrants that, except as set forth on Schedule B,
      the rights granted to the Holder hereunder do not in any way conflict with
      and are not inconsistent with the rights granted to the holders of the
      Company's securities under any such agreements.

<PAGE>   14

            (c)    Successors and Assigns. Subject to the provisions of
      paragraph 7 hereof, this Warrant shall inure to the benefit of and be
      binding upon the successors and assigns of each of the parties.

            (d)    Severability. In the event that any one or more of the
      provisions contained herein, or the application thereof in any
      circumstances, is held invalid, illegal or unenforceable, the validity,
      legality and enforceability of any such provision in every other respect
      and of the remaining provisions contained herein shall not be affected or
      impaired thereby.

            (e)    Amendments and Waivers. The provisions of this Warrant,
      including the provisions of this sentence, may not be amended, modified or
      supplemented, and waivers or consents to departures from the provisions
      hereof may not be given without the consent of both the Company and the
      Holder.

            (f)    Headings. The headings of this Warrant have been inserted as
      a matter of convenience and shall not affect the construction hereof.

            (g)    Applicable Law. This Warrant shall be governed by and
      construed in accordance with the laws of the Commonwealth of Pennsylvania.
      Each party hereto agrees to submit to the nonexclusive jurisdiction of the
      courts in the City of Pittsburgh in the Commonwealth of Pennsylvania in
      any action or proceeding arising out of or relating to this Agreement.

            (h)    Registration Provisions. Except as provided in the
      Registration Rights Agreement, the Company is not required under the terms
      hereof to register any securities issued pursuant hereto, and the
      subsequent transfer of any shares issued pursuant hereto may require
      registration under the Securities Act as well as under applicable state
      laws. In the event the shares issued upon the exercise of this Warrant are
      not registered, the Holder acknowledges that any stock certificate
      evidencing shares acquired on exercise of this Warrant shall contain a
      legend restricting transferability substantially as follows:

            THIS SECURITY HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE
            SECURITIES ACT OF 1933, AS AMENDED ("ACT"), OR THE SECURITIES LAWS
            OF ANY STATE AND MAY NOT BE OFFERED OR SOLD UNLESS REGISTERED AND/OR
            QUALIFIED PURSUANT TO THE RELEVANT PROVISIONS OF FEDERAL AND STATE
            SECURITIES LAWS OR AN EXEMPTION FROM SUCH REGISTRATION OR
            QUALIFICATION IS APPLICABLE. THEREFORE, NO SALE OR TRANSFER OF THIS
            SECURITY SHALL BE VALID, AND THE ISSUER SHALL NOT BE REQUIRED TO
            GIVE ANY EFFECT TO ANY SUCH TRANSACTION, UNLESS (A) SUCH TRANSACTION
            SHALL HAVE BEEN REGISTERED UNDER THE ACT AND QUALIFIED OR APPROVED
            UNDER APPROPRIATE STATE SECURITIES LAWS, OR (B) THE ISSUER SHALL
            HAVE FIRST RECEIVED AN OPINION OF COUNSEL



                                     - 14 -
<PAGE>   15

            REASONABLY SATISFACTORY TO IT THAT SUCH REGISTRATION, QUALIFICATION
            OR APPROVAL IS NOT REQUIRED.
