         5.       Adjustment of Exercise Price; Number of Shares and Nature of
Securities Issuable Upon Exercise of Warrants.

                  (a) Exercise Price: Adjustment of Number of Shares. The
Exercise Price shall be subject to adjustment from time to time as hereinafter
provided. Upon each adjustment of the Exercise Price, the Warrantholders shall
thereafter be entitled to purchase, at the Exercise Price resulting from such
adjustment, a number of shares determined by multiplying the Exercise Price in
effect immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment and dividing the product
thereof by the Exercise Price resulting from such adjustment.

                  (b) Reorganization, Reclassification, Consolidation, Merger
or Sale. If any capital reorganization or reclassification of the capital stock
of the Company, or any or any consolidation or merger of the Company with
another corporation, or the sale of all or substantially all of its assets to
another corporation shall be effected in such a way that holders of Common
Stock shall be entitled to receive cash, stock, securities or assets with
respect to or in exchange for Common Stock, then, as a condition of such
reorganization, reclassification, consolidation, merger or sale, lawful and
adequate provisions shall be made whereby the Warrantholders shall thereafter
have the right to purchase and receive upon the basis and upon the terms and
conditions specified in this Warrant upon exercise of this Warrant and in lieu
of the shares of the Common Stock of the Company immediately theretofore
purchasable and receivable upon the exercise of the rights represented hereby,
such cash, shares of stock, securities or assets as may be issued or payable
with respect to or in exchange for a number of outstanding shares of Common
Stock equal to the number of shares of such Common Stock immediately
theretofore purchasable and receivable upon the exercise of the rights
represented hereby, and in any such case appropriate provision shall be made
with respect to the rights and interests of the Warrantholders to the end that
the provisions hereof (including, without limitation, provisions for
adjustments of the Exercise Price and of the number of shares purchasable and
receivable upon the exercise of this Warrant) shall thereafter be applicable,
as nearly as may be, in relation to any shares of stock securities or assets
thereafter deliverable upon the exercise hereof.

                  (c) Stock Splits and Reverse Splits. In case at any time the
Company shall subdivide its outstanding shares of Common Stock into a greater
number of shares, the Exercise Price in effect immediately prior to such
subdivision shall be proportionately reduced and the number of shares of Common
Stock purchasable pursuant to this Warrant immediately prior to


                                       4
<PAGE>   5

such subdivision shall be proportionately increased, and conversely, in case at
any time the Company shall combine its outstanding shares of Common Stock into
a smaller number of shares, the Exercise Price in effect immediately prior to
such combination shall be proportionately increased and the number of shares of
Common Stock purchasable upon the exercise of this Warrant immediately prior
to such combination shall be proportionately reduced.

                  (d) Dissolution, Liquidation and Wind-Up. In case the Company
shall, at any time prior to the expiration of this Warrant, dissolve, liquidate
or wind up its affairs, the Warrantholders shall be entitled, upon the exercise
of this Warrant, to receive, in lieu of the shares of Common Stock of the
Company which such Warrantholders would have been entitled to receive, the same
kind and amount of assets as would have been issued, distributed or paid to
such Warrantholders upon any such dissolution, liquidation or winding up with
respect to such shares of Common Stock of the Company, had such Warrantholders
been the holders of record of the Warrant Shares receivable upon the exercise
of this Warrant on the record date for the determination of those persons
entitled to receive any such liquidating distribution. After any such
dissolution, liquidation or winding up which shall result in any cash
distribution in excess of the Exercise Price provided for by this Warrant, the
Warrantholders may, at each such Warrantholder's option, exercise the same
without making payment of the Exercise Price, and in such case the Company
shall, upon the distribution to said Warrantholders, consider that said
Exercise Price has been paid in full to it and in making settlement to said
Warrantholders, shall deduct from the amount payable to such Warrantholders an
amount equal to such Exercise Price.

                  (e) Adjustment Certificate. In each case of an adjustment in
the number of shares of Common Stock or other stock, securities or property
receivable on the exercise of the Warrants, the Company shall compute such
adjustment in accordance with the terms of this Warrant and prepare and duly
execute and deliver to the Warrantholders a certificate setting forth such
adjustment and showing in detail the facts upon which such adjustment is based.

         6.       Social Agreements of the Company.

                  (a) Reservation of Shares. The Company covenants and agrees
that all Warrant Shares will, upon issuance, be validly issued, fully paid and
nonassessable and free from all preemptive rights of any stockholder, and from
all taxes, liens and charges with respect to the issue thereof. 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, a sufficient number of shares of Common Stock to
provide for the exercise of the rights represented by this Warrant.

                  (b) Avoidance of Certain Actions. The Company will not, by
amendment of its Certificate of Incorporation or through any reorganization,
transfer of assets, consolidation, merger, issue or sale of securities or
otherwise, avoid or take any action which would have the effect of avoiding 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
carrying out all of the provisions of this Warrant and in taking all of such
actions as my be necessary or appropriate in order to protect the rights of the
Warrantholders against impairment of their rights hereunder.

will, at its expense, obtain and maintain the approval for listing upon
official notice of issuance of all Warrant Shares and maintain the listing of
Warrant Shares after their issuance; and the Company will so list on such
national securities exchange, and will maintain such listing of, any other
securities that at any time are issuable upon exercise of this Warrant if and
at the time any securities of the same class shall be listed on such national
securities exchange by the Company.

         7.       Fractional Shares. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant. With
respect to any fraction of a share called for upon exercise hereof, such
fraction shall be rounded to the nearest whole share. A fraction of one-half
shall be rounded up to the next highest integer.

         8.       Notices of Stock Dividends. Subscriptions, Reclassifications.
Consolidations, Mergers, etc., If at any time: (i) the Company shall declare a

net earnings after taxes for the prior fiscal year, or (ii) the Company shall
authorize the granting to the holders of Common Stock of rights to subscribe
for or purchase any shares of capital stock of class or of any other rights; or
(iii) there shall be any capital reorganization, or reclassification, or
redemption of the capital stock of the Company, or consolidation or merger of
the Company with, or sale of all or substantially all of its assets to, another
corporation or firm; or (iv) there shall be a voluntary or involuntary
dissolution, liquidation or winding up of the Company; or (v) the Company
proposes to effect a Public Offering, then the Company shall give to the
Warrantholders at the addresses of such Warrantholders as shown on the books of
the Company, at least forty-five (45) days prior to the applicable record date
hereinafter specified, a written notice summarizing such action or event and
stating the record date for any such dividend or rights (or, if a record date
is not to be selected, the date as of which the holders of Common Stock of
record entitled to such dividend or rights are to be determined), the date on
which any such reorganization, reclassification, consolidation, merger, sale of
assets, dissolution, liquidation or winding up or Public Offering is expected
to become effective, and the date as of which it is expected the holders of
Common Stock of record shall be entitled to effect any exchange of their shares
of Common Stock for cash (or cash equivalent), securities or other property
deliverable upon any such reorganization, reclassification, consolidation,
merger, sale of assets, dissolution, liquidation or winding up or Public
Offering.

        9.        Registered Holder, Transfer of Warrants or Warrant Shares.

                  (a) Maintenance of Registration Books; Ownership of this
Warrant. The Company shall keep at its principal office a register in which the
Company shall provide for the registration, transfer and exchange of this
Warrant. The Company shall not at any time, except upon the dissolution,
liquidation or winding-up of the Company, close such register so as to result
in preventing or delaying the exercise or transfer of this Warrant.

                  (b) Exchange and Replacement. To the extent permissible under
any applicable securities laws, this warrant is exchangeable upon surrender
hereof by the registered

Series C Preferred Stock in accordance with Section 2 of that certain Amended
and Restated Investors' Rights Agreement ("Investors' Rights Agreement"), dated

Stock, except that Holder shall be required to approve any waiver or amendment

Company is a corporation duly organized, validly existing and in good standing

Warrant has been duly executed on behalf of the Company and constitutes the
legal, valid and binding obligation of the Company enforceable in accordance

performance of this Warrant nor the issuance of the shares of Common Stock
issuable upon exercise of this Warrant


                                       7
<PAGE>   8

         12.      Representations and Warranties of the Warrantholder. This
Warrant has been issued by the Company in reliance upon the following
representations and covenants of Warrantholder.

                  (i)      Investment Purpose. This Warrant and the Warrant
Shares will be acquired for investment for the Warrantholder's own account, and
not as a nominee or agent and not with a view to the sale or distribution of
any part thereof, and the Warrantholder has no present intention of selling,
granting any participation in or otherwise distributing the same. The
Warrantholder further represents that it does not have any contract,
undertaking, agreement or arrangement with any person to sell, transfer or
grant participations to such person, or to any third person, with respect to
this Warrant.

                  (ii)     Private Issue. The Warrantholder understands (i)
that the Warrant and the Warrant Shares issuable upon exercise of this Warrant
are not registered under the Securities Act, or qualified under applicable
state securities laws on the ground that the issuance of this Warrant will be
exempt from the registration and qualifications requirements thereof, and (ii)
that the Company's reliance on such exemption is predicated on the
representations set forth in this Section 10.

                  (iii)    Disposition of Warrantholder's Rights. In no event
will the Warrantholder make a disposition of the Warrant Shares issuable upon
exercise of this Warrant unless and until (i) it shall have notified the
Company of the proposed disposition, and (ii) if requested by the Company, it
shall have furnished the Company with an opinion of counsel satisfactory to the
Company and its counsel to the effect that (A) appropriate action necessary for
compliance with the Securities Act has been taken, or (B) an exemption from the
registration requirements of the Securities Act is available. Notwithstanding
the foregoing, the restrictions imposed upon the transferability of the Warrant
Shares shall terminate as to this Warrant and any particular share of Common
Stock when (1) such security shall have been effectively registered under the
Securities Act and sold by the Holder thereof in accordance with such
registration or (2) such security shall have been sold without registration in
compliance with Rule 144 under the Securities Act, or (3) a letter shall have
been issued to the Warrantholder at its request by the staff of the Securities
and Exchange Commission or a ruling shall have been issued to the Warrantholder
at its request by such Commission stating that no action shall be recommended
by the staff or taken by such Commission, as the case may be, if such security
is transferred without registration under the Securities Act in accordance with
the conditions set forth in such letter or



                                       8
<PAGE>   9

ruling and such letter or ruling specifies that no subsequent restrictions on
transfer are required. Whenever the restrictions imposed hereunder shall
terminate, as hereinabove provided, the Warrantholder or the Holder of a share
of Common Stock issued upon exercise of this Warrant as to which such
restrictions have terminated shall be entitled to receive from the Company,
without expense to such Holder, one or more new certificates for the Warrant or
for such shares of Common Stock not bearing any restrictive legend.

                  (iv)     Rule 144. The Warrantholder acknowledges that it has
received and reviewed a copy of Rule 144 promulgated under the Securities Act,
which permits limited public resales of securities acquired in a non-public
offering, subject to the satisfaction of certain conditions.

                  (v)      Sale of Warrant. The Warrantholder acknowledges that
in the event the applicable requirements of Rule 144 are not met, registration
under the Securities Act or compliance with another exemption from registration
will be required for any disposition of this Warrant or the Warrant Shares. The
Warrantholder understands that although Rule 144 is not exclusive, the
Securities and Exchange Commission has expressed its opinion that persons
proposing to sell restricted securities received in a private offering other
than in a registered offering or pursuant to Rule 144 will have a substantial
burden of proof in establishing that an exemption from registration is
available for such offers or sales and for such persons and the brokers who
participate in the transaction do so at their own risk. The Warrantholder also
acknowledges that it is not receiving any rights with respect to registration of
this Warrant or the Warrant Shares under the Securities Act.

                  (vi)     Financial Risk. The Warrantholder has such knowledge
and experience in financial and business matters as to be capable of evaluating
the merits and risks of its investment, and has the ability to bear the
economic risks of its investment.

                  (vii)    Accredited Investor. The Warrantholder is an
"accredited investor" within the meaning of Rule 501 of Regulation D
promulgated under the Act.

                  (viii)   No Public Market. The Warrantholder understands that
no public market now exists for any of the securities issued by the Company.

                  (ix)     Receipt of Information. The Warrantholder has
received and reviewed this Warrant; it, its attorney and its accountant have
had access to, and an opportunity to review all documents and other materials
requested of, the Company; it and they have been given an opportunity to ask
any and all questions or, and receive answers from, the Company concerning the
terms and conditions of this Warrant and to evaluate the suitability of an
investment in this Warrant; and, in evaluating the suitability of an investment
in this Warrant; it and they have not relief upon any representations or other
information (whether oral or written) other than as set forth herein.

         14.      Lock-Up-Period. Warrantholder hereby agrees that, if so
requested by the Company or any representative of the underwriters (the
"Managing Underwriter") in connection with any registration of the offering of
any securities of the Company under the Securities Act or a public offering
that is exempt from the Securities Act (e.g. Regulation A offering),
Warrantholder shall not sell or otherwise transfer any Warrant Shares or other
securities of the Company during the


                                       9

180-day period (or such other period as may be requested in writing by the
Managing Underwriter and agreed to in writing by the Company) (the "Market
Standoff Period") following the effective date of a registration statement of
the Company filed under the Securities Act or the commencement date of such an
exempt public offering. Such restriction shall apply only to the first
registration statement or exempt public offering of the Company to become
effective under the Securities Act that includes securities to be sold on
behalf of the Company to the public in an underwritten public offering. The
Company may impose stop-transfer instructions with respect to securities
subject to the foregoing restrictions until the end of such Market Standoff
Period.
