        unlisted trading privileges, the fair market value shall be the average
        of the means of the last bid and asked prices reported on the last ten
        (10) trading days (or all such trading days such Preferred Stock has
        been traded if fewer than 10 trading days) before the date of the
        election (1) by the Nasdaq Stock Market or (2) if reports are
        unavailable under clause (1) above, by the National Quotation Bureau
        Incorporated; and

                (C) If the Preferred Stock is not so listed or admitted to
        unlisted trading privileges and bid and ask prices are not reported, the
        fair market value shall be the price per share which the Company could
        obtain from a willing buyer for shares sold by the

written notice shall specify the amount and character of any such dividend,
distribution or right(s), and shall set forth, in reasonable detail, the matter
requiring any such vote of the shareholders.

        6. Fractional Shares. No fractional shares of Preferred Stock will be
issued in connection with any exercise hereunder, but in lieu of such fractional
shares the Company shall make a cash payment therefor based upon the per share

           Preferred Stock.

                (a) Compliance with Securities Act. The holder of this Warrant,

each subsequent holder of this Warrant agrees to give written notice to the
Company prior thereto, describing briefly the manner thereof, together with a

under the Securities Act certificates for this Warrant or such Shares or Common
Stock to be sold or otherwise disposed of require any restrictive legend as to

transferability in order to insure compliance with the Securities Act unless, in
the aforesaid opinion of counsel for the holder, such legend is not required in
order to insure compliance with the Securities Act. Nothing herein shall
restrict the transfer of this Warrant or any portion hereof by the initial
holder hereof to any partnership affiliated with the initial holder, or to any
partner of any such partnership provided such transfer may be made in compliance
with applicable federal and state securities laws. The Company may issue stop
transfer instructions to its transfer agent in connection with the foregoing
restrictions.

obligation to the holder hereof in respect of any rights (including, without
limitation, any right to registration of the Shares in accordance with Section
9) to which the holder hereof shall continue to be entitled after such exercise
in accordance with this Warrant; provided, that the failure of the holder hereof
to make any such request shall not affect the continuing obligation of the
Company to the holder hereof in respect of such rights.

        16. Lost Warrants or Stock Certificates. The Company covenants to the
holder hereof that upon receipt of evidence reasonably satisfactory to the
Company of the loss, theft, destruction, or mutilation of this Warrant or any

deliver a new Warrant or stock certificate, or like tenor, in lieu of the lost,
stolen, destroyed or mutilated Warrant or stock certificate.

through any reorganization, recapitalization, 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 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 be necessary or appropriate in order to

                              ADJUSTMENT PROVISIONS

        1. Capitalized Terms. Capitalized terms used in this Appendix I that are
not otherwise defined herein shall have the respective meanings assigned to them
in the Warrant, dated as of January 28, 1999, to which this Appendix I is
attached, if therein defined.

        2. [Intentionally Deleted]

        3. Reclassification or Merger. In case of any reclassification, change
or conversion of securities of the class issuable upon exercise of this Warrant
(other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination), or in
case of any merger of the Company with or into another corporation or entity
(other than a merger with another corporation in which the Company is a
continuing corporation and which does not result in any reclassification or
change of outstanding securities issuable upon exercise of this Warrant), or in
case of any sale of all or substantially all of the assets of the Company, the
Company, or such successor or purchasing corporation or entity, as the case may
be, shall execute a new Warrant (in form and substance satisfactory to the
holder of this Warrant) providing that the holder of this Warrant shall have the
right to exercise such new Warrant and upon such exercise to receive, in lieu of
each share of Preferred Stock theretofore issuable upon exercise of this
Warrant, the kind and amount of shares of stock, other securities, money and
property receivable upon such reclassification, change or merger by a holder of
one share of Preferred Stock. Such new Warrant shall provide for adjustments
that shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Appendix I. The provisions of this Section 3 shall
similarly apply to successive reclassifications, changes, mergers and transfers.

        4. Subdivision or Combination of Shares. If the Company at any time
while this Warrant remains outstanding and unexpired shall subdivide or combine
its Preferred Stock, the Exercise Price and the number of Shares issuable upon
exercise hereof shall be proportionately adjusted.

        5. Stock Dividends. If the Company at any time while this Warrant is
outstanding and unexpired shall pay a dividend payable in shares of Preferred
Stock, then the Exercise Price shall be adjusted, from and after the date of
determination of shareholders entitled to receive such dividend or distribution,
to that price determined by multiplying the Exercise Price in effect immediately
prior to such date of determination by a fraction (a) the numerator of which
shall be the total number of shares of Preferred Stock outstanding immediately
prior to such dividend or distribution, and (b) the denominator of which shall
be the total number of shares of Preferred Stock outstanding immediately after
such dividend or distribution and the number of Shares subject to this Warrant
shall be proportionately adjusted.

        6. Other Distributions. In the event the Company shall declare a
dividend or distribution payable in cash, securities of other persons, evidences
of indebtedness issued by the

                                       13
<PAGE>   14

Company or other persons, assets or options or rights not referred to in
Sections 3,4 or 5 of this Appendix I, then, in each such case, provision shall
be made by the Company such that the holder of this Warrant shall receive upon
exercise of this Warrant a proportionate share of any such dividend or
distribution as though it were the holder of the Shares (or Common Stock
issuable upon conversion thereof) as of the record date fixed for the
determination of the shareholders of the Company entitled to receive such
dividend or distribution.

        7. Notice of Adjustments. Whenever the Exercise Price shall be adjusted
pursuant to the provisions hereof, the Company shall within thirty (30) days of
such adjustment deliver a certificate signed by its chief financial officer to
the registered holder(s) hereof setting forth, in reasonable detail, the event
requiring the adjustment, the amount of the adjustment, the method by which such
adjustment was calculated, and the Exercise Price after giving effect to such
adjustment.

<PAGE>   17

of Exercise form attached hereto as Exhibit A-1 duly executed) at the principal
office of the Company and by the payment to the Company, by cash, check or
cancellation of indebtedness, of an amount equal to the Exercise Price per share
multiplied by the number of Shares then being purchased; or (b) if in connection
with a sale of Shares pursuant to a registered public offering of the Company's

contingent upon the close of such offering, at the principal office of the
Company together with notice of arrangements reasonably satisfactory to the
Company for payment to the Company from the proceeds of the sale of shares to be
sold by the holder in such public offering of an amount equal to the Exercise
Price per share multiplied by the number of Shares then being purchased. The
person or persons in whose name(s) any certificates representing Shares shall be
issuable upon exercise of this Warrant shall be deemed to have become the
holder(s) of record of, and shall be treated for all purposes as the record
holder(s) of, the Shares represented thereby (and such Shares shall be deemed to
have been issued immediately prior to the close of business on the date or dates
upon which this Warrant is exercised. In the event of any exercise of this
Warrant, certificates for the Shares so purchased shall be delivered to the
holder hereof as soon as possible and in any event within fifteen (15) days of
receipt of such notice (or, following, the Company's initial public offering,
within five (5) days of receipt of such notice) and, unless this Warrant has
been fully exercised or expired, a new Warrant representing the portion of the
Shares, if any, with respect to which this Warrant shall not then have been
exercised shall also be issued to the holder hereof as soon as possible
thereafter.

                2.2 Automatic Exercise. To the extent this Warrant is not
previously exercised, and if the fair market value of one share of the Company's
Preferred Stock is greater than the Exercise Price then in effect, this Warrant
shall be deemed automatically exercised pursuant to Section 2.3 below (even if
not surrendered) immediately before its expiration. For purposes of such
automatic exercise, the fair market value of one share of the Company's
Preferred Stock upon such expiration shall be determined pursuant to Section
2.3(b) below. To the extent this Warrant or any portion thereof is deemed
automatically exercised pursuant to this Section 2.2, the Company agrees to
promptly notify the holder hereof of the number of Shares, if any, the holder
hereof is to receive by reason of such automatic exercise.

the holder under the terms of this Warrant, the holder may elect to convert this
Warrant or any portion thereof (the "Conversion Right") into shares of Preferred
Stock, the aggregate value of which shares shall be equal to the value of this
Warrant or the portion thereof being converted. The Conversion Right may be
exercised by the holder by surrender of this Warrant at the principal office of
the Company together with notice of the holder's intention to exercise the
Conversion Right, in which event the Company shall issue to the holder a number
of shares of the Company's Preferred Stock computed using the following formula:

                                       2

                                        ------
                                    X =    A

Where:  X = The number of shares of Preferred Stock to be issued to the holder.

        Y = The number of shares of Preferred Stock purchasable under this
            Warrant subject to the exercise election.

        A = The fair market value of one share of the Company's Preferred
            Stock.

        B = Exercise Price (as adjusted to the date of such calculations).

                (b) For the purposes of this Section 2.3, the "fair market
value" per share of the Company's Preferred Stock shall mean:

                        (i) If the Conversion Right is exercised in connection
with and contingent upon the Company's initial public offering, and if the
Company's registration statement relating to such offering has been declared
effective by the Securities and Exchange Commission, then the initial "Price to
Public" specified in the final prospectus with respect to such offering; or

                        (ii) If the Conversion Right is not exercised in
connection with and contingent upon the Company's initial public offering, then
as follows:

                (A) If the Preferred Stock is traded on a national securities
exchange or admitted to unlisted trading privileges on such an exchange, or is
listed on the Nasdaq National Market (the "National Market System"), the fair
market value shall be the average of the last reported sale prices of the
Preferred Stock on such exchange or on the Nasdaq National Market on the last
ten (10) trading day (or all such trading days such Preferred Stock has been
traded if fewer than 10 trading days) before the effective date of exercise of
the Conversion Right or if no such sale is made on any such day, the mean of the
closing bid and asked prices for such day on such exchange or on the Nasdaq
National Market;

                (B) If the Preferred Stock is not so listed or admitted to
unlisted trading privileges, the fair market value shall be the average of the
means of the last bid and asked prices reported on the last ten (10) trading
days (or all such trading days such Preferred Stock has been traded if fewer
than 10 trading days) before the date of the election (1) by the Nasdaq Stock
Market or (2) if reports are unavailable under clause (1) above, by the National
Quotation Bureau Incorporated; and

                (C) If the Preferred Stock is not so listed or admitted to
unlisted trading privileges and bid and ask prices are not reported, the fair
market value shall be the price per share which the Company could obtain from a
willing buyer for shares sold by the Company from authorized but unissued
shares, as such price shall be determined by mutual agreement of the Company and
the holder of this Warrant.

        3. Stock Fully Paid; Reservation of Shares. All Shares that may be
issued upon the exercise of this Warrant, and all Common Stock issuable upon
conversion of the Shares shall, upon issuance, be validly issued, fully paid and
nonassessable, and free from all taxes, liens and charges with respect to the
issue thereof. During the period within which this Warrant may be exercised, the
Company will at all times have duly authorized and reserved, for the purpose of
issuance upon exercise of this Warrant, a sufficient number of shares of
Preferred Stock (and Common Stock issuable upon conversion thereof).

        4. Adjustments to Exercise Price and Number of Shares. The number and
kind of securities purchasable upon the exercise of this Warrant and the
Exercise Price shall be subject to adjustment from time to time as set forth in
Appendix I hereto upon the occurrence of certain events described therein. The
provisions of Appendix I are incorporated by reference herein with the same
effect as if set forth in full herein.

        5. Notices of Record Date. In the event of any taking by the Company of
a record of its shareholders for the purpose of determining shareholders who are
entitled to receive payment of any dividend or other distribution, any right to
subscribe for, purchase or otherwise acquire any share of any class or any other
securities or property, or to receive any other right, or for the purpose of
determining shareholders who are entitled to vote in connection with any
proposed merger or consolidation of the Company with or into any other
corporation, or any proposed sale, lease or conveyance of all or substantially
all of the assets of the Company, or any proposed liquidation, dissolution or
winding up of the Company, then, in connection with each such event, the Company
shall mail to the holder of this Warrant at least twenty (20) days prior written
notice of the date on which any such record is to be taken for the purpose of
such dividend, distribution, right(s) or vote of the shareholders. Each such
written notice shall specify the amount and character of any such dividend,
distribution or right(s), and shall set forth, in reasonable detail, the matter
requiring any such vote of the shareholders.

        6. Fractional Shares. No fractional shares of Preferred Stock will be
issued in connection with any exercise hereunder, but in lieu of such fractional
shares the Company shall make a cash payment therefor based upon the per share
fair market value of the Preferred Stock on the date of exercise.

        7. Compliance with Securities Act; Disposition of Warrant or Shares of
Preferred Stock.

                (a) Compliance with Securities Act. The holder of this Warrant,
by acceptance hereof, agrees that this Warrant, the Shares to be issued upon
exercise hereof and the Common Stock to be issued upon conversion of such Shares
are being acquired for investment purposes only and that such holder will not
offer, sell or otherwise dispose of this Warrant or any Shares to be issued upon
exercise hereof (or Common Stock issued upon conversion of such Shares) except
under circumstances which will not result in a violation of the Securities Act.
This Warrant and all Shares issued upon exercise of this Warrant (unless
registered under the Securities Act) shall be stamped or imprinted with a legend
in substantially the following form:
