                                                                  EXECUTION COPY

                      STANDBY SECURITIES PURCHASE AGREEMENT

            THIS STANDBY SECURITIES PURCHASE AGREEMENT (this "AGREEMENT"), dated
as of June 2, 2005, is made by and between DDi Corp., a Delaware corporation
(the "COMPANY"), and, separately, each of the purchasers set forth on Exhibit A
attached hereto (each, a "PURCHASER" and collectively, the "PURCHASERS"). The
Company and each Purchaser are sometimes referred to individually as a "PARTY"
and, collectively, as the "PARTIES."

                              W I T N E S S E T H:

      WHEREAS, the Company intends to undertake a rights offering (the "RIGHTS
OFFERING") pursuant to which the Company will offer to the Company's common
stockholders (the "STOCKHOLDERS") rights (the "RIGHTS") to purchase shares (the
"OFFERED SHARES") of the Company's common stock, par value $0.001 per share (the
"COMMON STOCK");

      WHEREAS, pursuant to the terms of the Rights Offering, each of the
Stockholders will have the right to purchase its pro rata share of the Offered
Shares;

      WHEREAS, the Company has filed a registration statement on Form S-3 (the
"REGISTRATION STATEMENT") with the Securities and Exchange Commission (the
"SEC") covering the offering and sale of the Offered Shares to the Stockholders;
and

      WHEREAS, the Company wishes to provide for the purchase and sale of the
Unsubscribed Shares (as defined below) and to establish certain rights and
obligations in connection therewith.

      NOW, THEREFORE, in consideration of the premises and the mutual
representations, warranties, covenants and agreements set forth in this
Agreement, and for good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged, the Company and each of the Purchasers, acting
separately, agree as follows:

                                   ARTICLE I

                           ISSUANCE AND SALE OF SHARES

      1.1 Issuance, Purchase and Sale. Subject to the terms and conditions and
in reliance upon the representations and warranties herein set forth, the
Company agrees to sell to each of the Purchasers, and each of the Purchasers
separately agrees to purchase from the Company, severally and not jointly, at a
purchase price per share equal to the subscription price per share specified on
the cover page of the prospectus (the "PROSPECTUS") included in the Registration
Statement at the time it is declared effective by the SEC or on the cover page
to the prospectus relating to the Registration Statement that is filed with the
SEC pursuant to Rule 424(b) under the Securities Act (the "PER SHARE
SUBSCRIPTION PRICE"), a specified portion, as set forth in Exhibit A hereto
under the column titled "Proportionate Share" of the number of Offered Shares
equal to the Shortfall (as defined below) divided by the Per Share Subscription
Price (all such Offered Shares not subscribed for and purchased by the
Stockholders in the Rights Offering being referred to herein as the
"UNSUBSCRIBED SHARES"). The Parties agree that the Per Share

                                       1
<PAGE>

Subscription Price will equal fifty percent (50%) of the Average Share Price on
the second Business Day immediately prior to the date on which the Rights
Offering is commenced. In no event shall the number of Unsubscribed Shares
multiplied by the Per Share Subscription Price result in an amount in excess of
Seventy Five Million Dollars ($75,000,000). The "SHORTFALL" shall be equal to
the amount by which $75,000,000 (the "OFFERING PRICE") exceeds the aggregate
subscription price to be paid by the Stockholders (other than the Purchasers
pursuant to this Agreement) who subscribe for and purchase shares of Common
Stock offered in the Rights Offering on or before the expiration date thereof.
Notwithstanding anything in the foregoing to the contrary, in no event shall any
Purchaser be obligated to purchase a number of Unsubscribed Shares in excess of
the product of such Purchaser's "Proportionate Share" specified on Exhibit A and
the aggregate number of Unsubscribed Shares, and no Purchaser shall be obligated
to purchase any Unsubscribed Shares that any other Purchaser is obligated to
purchase pursuant to this Agreement.

      1.2 Closing. Upon the terms and subject to the satisfaction of the
conditions contained in Article VI of this Agreement, the closing of the
purchase and sale of the Unsubscribed Shares (the "CLOSING") shall take place at
the offices of Paul, Hastings, Janofsky & Walker LLP, 695 Town Center Drive,
Seventeenth Floor, Costa Mesa, California 92626, at 9:00 a.m., local time, on
the third Business Day following the expiration of the Rights Offering, provided
that the Closing may take place at such other place, time or date as shall be
mutually agreed upon by the Company and the Required Purchasers (the date of the
Closing, the "CLOSING DATE") it being understood, however, that each Purchaser's
right and obligation to purchase its Proportionate Share of the Unsubscribed
Shares shall be fixed, subject to the conditions contained in Article VI, as of
the time of the expiration of the Rights Offering.

      1.3 Deliveries. At the Closing (i) the Company shall deliver to the
Purchasers stock certificates registered in the name of the Purchasers,
representing the Unsubscribed Shares purchased by the Purchasers hereunder and
(ii) each Purchaser shall deliver to the Company the aggregate purchase price
for the Unsubscribed Shares equal to the product of (A) the number of
Unsubscribed Shares to be acquired by such Purchaser and (B) the Per Share
Subscription Price, which shall be paid by such Purchaser to the Company via
wire transfer of immediately available funds to an account designated in writing
by the Company at least two Business Days prior to the Closing Date.
Certificates for the Unsubscribed Shares shall be registered in such names and
in such denominations as each Purchaser may request not less than two Business
Days prior to the Closing Date.

      1.4 Standby Commitment Fee. As compensation to the Purchasers for
satisfying their commitments, the Company agrees to issue to each of the
Purchasers that has fulfilled its obligation to purchase Unsubscribed Shares
pursuant to this Agreement warrants to purchase shares of the Company's Common
Stock (the "STANDBY COMMITMENT FEE WARRANTS"). The number of Standby Commitment
Fee Warrants issuable to each Purchaser shall be determined in accordance with
the following formula:

                                       2
<PAGE>

            N = P x 10.7% x O

where

            N = the number of Standby Commitment Fee Warrants issuable to a
                Purchaser;

            P = the Proportionate Share of such Purchaser; and

            O = the total number of shares of Common Stock outstanding on a
fully diluted basis (without giving effect to issuances of Common Stock and
securities exercisable for Common Stock to the Company's management under the
proposed 2005 Incentive Plan and assuming that two-thirds of the Company's
Series B Preferred Stock outstanding on the date of this Agreement has been
repurchased or redeemed) following consummation of the Rights Offering and the
purchase of the Unsubscribed Shares pursuant to this Agreement.

The Standby Commitment Fee Warrants shall be in the form attached hereto as
Exhibit B, with each such warrant having an initial exercise price equal to the
Per Share Subscription Price and an expiration date of July 31, 2006. Such
Standby Commitment Fee Warrants shall be delivered to the Purchasers on the
Closing Date, but each Purchaser shall be deemed to have earned its Standby
Commitment Fee Warrants effective as of the time its right and obligation to
purchase its Proportionate Share of the Unsubscribed Shares shall become fixed,
as provided in Section 1.2.

      1.5 Capitalized Terms. Capitalized terms not otherwise defined in this
Agreement shall have the meanings ascribed to such terms in Section 9.1 hereof.

      1.6 Reallocation of Unsubscribed Shares. Notwithstanding anything in this
Agreement to the contrary, each Purchaser agrees that it will not purchase
shares of Common Stock pursuant to the Rights Offering and/or this Agreement if
such purchases would cause such Purchaser and its Affiliates to beneficially own
40% or more of the shares of outstanding voting stock of the Company, determined
in accordance with Rule 13d-3 promulgated under the Exchange Act. In connection
therewith, the Company shall have the right, in its sole discretion, to reduce
the amount of Unsubscribed Shares that any Purchaser acquires, and to reallocate
such Unsubscribed Shares to another Purchaser who agrees to take such additional
Unsubscribed Shares, such that after giving effect to the Rights Offering and
the issuance of Common Stock under this Agreement, no Purchaser and/or its
affiliates will beneficially own more than 39.9% of the shares of outstanding
voting stock of the Company, determined in accordance with Rule 13d-3
promulgated under the Exchange Act. If any reallocation is made pursuant to this
Section 1.6, the Proportionate Share of the affected Purchasers shall be
modified accordingly for purposes of issuance of the Standby Commitment Fee
Warrants pursuant to Section 1.3 and the Break-up Warrants pursuant to Section
7.3.

                                   ARTICLE II

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

      The Company represents and warrants to each of the Purchasers, that the
statements contained in this Article II are true and correct as of the date
hereof and will be true and correct as of the Closing as though made as of the
Closing.

the requisite corporate power

                                       3
<PAGE>

and authority to own, lease and operate its properties and assets and to carry
on its business as it is now being conducted. The Company is duly qualified to
conduct business and is in good standing as a foreign corporation in each
jurisdiction in which the nature of the business conducted or property owned,
operated or leased by it makes such qualification necessary, except where the
failure to be so qualified or in good standing, as the case may be, would not,
individually or in the aggregate, have a Material Adverse Effect.

      2.2 Due Authorization. The Company has the requisite corporate power and
authority to enter into this Agreement and the Registration Rights Agreement (as
defined below) and to consummate the transactions contemplated hereby and
thereby. The execution and delivery by the Company of this Agreement and the
Registration Rights Agreement, the issuance, sale and delivery of the
Unsubscribed Shares, the issuance of the Standby Commitment Fee Warrants and the
consummation by the Company of the transactions contemplated hereby and thereby
(a) are within the corporate power and authority of the Company and (b) have
been duly authorized by all necessary corporate action of the Company; provided
that the transactions contemplated by this Agreement, the Registration Rights
Agreement and the Warrants (collectively, the "TRANSACTION DOCUMENTS") and the
issuance of the Common Stock in the Rights Offering, the issuance of the
Unsubscribed Shares pursuant to this Agreement and the issuance of Common Stock
upon exercise of the Standby Commitment Fee Warrants is subject to the approval
thereof by the stockholders of the Company, including approval for increasing
the Company's authorized shares of Common Stock. This Agreement has been duly
and validly executed and delivered by the Company. Assuming the due
authorization, execution and delivery by each of the Purchasers of this
Agreement, this Agreement and the Registration Rights Agreement constitute valid
and binding obligations of the Company enforceable against it in accordance with
their respective terms, except (x) as enforcement hereof may be limited by
bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium, or
other laws affecting the enforcement of creditors' rights in general, and except
that the enforceability of this Agreement is subject to general principles of
equity (regardless of whether such enforceability is considered in a proceeding
in equity or at law), and (y) as rights to indemnity and contribution hereunder
may be limited by Federal or state securities law and/or public policy.
Following approval by the stockholders of the Company of an increase in the
Company's authorized shares of Common Stock, (i) the shares issuable in the
Rights Offering shall be validly reserved for issuance and, when issued and
delivered in accordance with the terms of the Rights Offering, shall be validly
issued, fully paid and non-assessable; (ii) the Unsubscribed Shares shall be
validly reserved for issuance and, when issued and delivered in accordance with
the terms of this Agreement, shall be validly issued, fully paid and

of the Standby Commitment Fee Warrants or the Break-up Warrants (as defined
below) (such shares, the "WARRANT SHARES") shall be validly reserved for
issuance and, when issued and delivered in accordance with the terms of this
Agreement and the terms of the Standby Commitment Fee Warrants or the Break-up
Warrants, shall be validly issued, fully paid and non-assessable. Prior to the
consummation of the Rights Offering, the Company shall take all necessary
corporate action to convene a meeting of the Company's stockholders to vote to

authorization of a sufficient number of additional shares of Common Stock for
issuance in the Rights Offering, for issuance as Unsubscribed Shares pursuant to
this Agreement and for issuance upon exercise of the Standby Commitment Fee
Warrants or the Break-up Warrants and to approve the issuance of such shares
(such approvals being referred to herein as the "STOCKHOLDER APPROVALS").

of incorporation or by-laws or other organizational documents of the Company or
any of its subsidiaries, and do not and will not conflict with, or result in a

(ii) if any condition to the Company's obligations to close at the Closing set

Agreement), and, in each case, the Required Purchasers have not waived such
breach or condition.

Purchaser shall be entitled to receive warrants to purchase shares of Common
Stock (the "BREAK-UP WARRANTS") in the form attached as Exhibit E. The number of
Break-up Warrants issuable to each Purchaser shall be determined in accordance
with the following formula:

                                       17
<PAGE>

            N = P x 10.7% x O x d

            P = the Proportionate Share of such Purchaser;

            O = the total number of shares of Common Stock outstanding on a
fully diluted basis (without giving effect to issuances of Common Stock and
securities exercisable for Common Stock to the Company's management under the
proposed 2005 Incentive Plan and assuming that two-thirds of the Company's
Series B Preferred Stock outstanding on the date of this Agreement has been
repurchased or redeemed) as of the date of the termination of this Agreement;
and

            d = 50%, if termination occurs prior to the effectiveness of the
Registration Statement and 100% if termination occurs following effectiveness of
the Registration Statement.

Each Break-up Warrant shall have an initial exercise price equal to 50% of the
Average Share Price on the date of the termination of this Agreement. Except as
set forth in or contemplated by Section 4.7(b)(ii), Section 7.2, Section 7.4 or
Article VIII hereof, the Purchasers' receipt of the Break-up Warrants pursuant

provisions of Section 7.1, this Agreement shall forthwith become void and there
shall be no further obligations on the part of the Company or any Purchaser or
their respective directors, officers, employees, agents or representatives,
except for the provisions of Section 8.1(a) (but only with respect to third
party claims or any claim for a breach of Section 4.7(b)(ii) hereof) and
Sections 7.2, 7.3, 8.2, 8.3, 8.4, 9.1, 9.2, 9.4, 9.5, 9.7, 9.8 and 9.10, which
shall survive any termination of this Agreement; provided, that nothing in this
Section 7.4 shall relieve any Party from liability for any willful breach of
this Agreement.

furnished by the Company to a Purchaser pursuant to this Agreement or (ii) third
party claims or demands relating to the fact that a Purchaser is a party to this
Agreement; provided that the Company shall not be required to indemnify a
Purchaser to the extent that the Losses arise from the gross negligence or
willful misconduct of such Purchaser or any of its affiliates.

            (b) Each Purchaser shall indemnify and hold harmless the Company and
its directors, officers, employees, agents, representatives, affiliates and
controlling Persons (within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act) against any and all Losses incurred or suffered
by such party arising out of or based upon any breach of a representation or
warranty or breach of or failure to perform any covenant or agreement on the
part of such Purchaser contained in this Agreement; provided that the Purchasers
shall not be required to indemnify the Company to the extent the Losses arise
from the gross negligence or willful misconduct of the Company or any of its
affiliates.

      8.2 Indemnification Procedures. All claims or demands for indemnification
under this Article VIII shall be asserted and resolved as follows:

            (a) In the event that any claim or demand for which a Party (the
"INDEMNIFYING PARTY") would be liable to the other Party (the "INDEMNIFIED
PARTY") hereunder is asserted against an Indemnified Party by a third party, the
Indemnified Party shall with reasonable promptness notify the Indemnifying Party
of such claim or demand (the "CLAIM NOTICE"), specifying the nature of such
claim or demand and the amount or the estimated amount thereof to the extent
then feasible (which estimate shall not be conclusive of the final amount of
such claim or demand). The Indemnifying Party shall have fifteen (15) days from
the receipt of the Claim Notice (the "NOTICE PERIOD") to notify the Indemnified
Party (i) whether or not the Indemnifying Party disputes the Indemnifying
Party's liability to the Indemnified Party hereunder with respect to such claim
or demand and (ii) if the Indemnifying Party does not dispute such liability,
whether or not the Indemnifying Party desires, at the sole cost and expense of
the Indemnifying Party, to defend against such claim or demand, provided that
the Indemnified Party is hereby authorized (but not obligated) prior to and
during the Notice Period to file any motion, answer or other pleading and to
take such action which the Indemnified Party shall reasonably deem necessary or
appropriate to protect the Indemnified Party's interests. In the event that the
Indemnifying Party notifies the Indemnified Party within the Notice Period that
the Indemnifying Party does not dispute the Indemnifying Party's obligation to
indemnify hereunder and desires to defend the Indemnified Party against such
claim or demand and except as hereinafter provided, the Indemnifying Party shall
have the right to defend (with counsel reasonably satisfactory to the
Indemnified Party) by appropriate proceedings.

            (b) An Indemnified Party shall have the right to employ separate
counsel in any such proceeding and to participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in
writing to pay such fees and expenses; (2) the Indemnifying Party shall have
failed promptly to assume the defense of such proceeding and to employ counsel
reasonably satisfactory to the Indemnified Party in any such proceeding; or (3)
the named parties to any such proceeding (including any impleaded parties)
include both such Indemnified Party and the

                                       19
<PAGE>

Indemnifying Party, and such Indemnified Party shall have been advised by
counsel that a conflict of interest is likely to exist if the same counsel were
to represent such Indemnified Party and the Indemnifying Party (in which case,
if such Indemnified Party notifies the Indemnifying Party in writing that it
elects to employ separate counsel at the expense of the Indemnifying Party, the
Indemnifying Party shall not have the right to assume the defense thereof and
the reasonable fees and expenses of one separate counsel, and one local counsel
in each applicable jurisdiction, shall be at the expense of the Indemnifying
Party).

            (c) All Losses (including any fees and expenses incurred in
connection with investigating or preparing to defend such action or proceeding)
will be paid to the Indemnified Party, as incurred, within ten (10) Business
Days of written notice thereof to the Indemnifying Party upon receipt of an
undertaking to repay such amount if it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder. The Indemnifying
Party will not consent to entry of any judgment or enter into any settlement or
otherwise seek to terminate any action or proceeding in which any Indemnified
Party is or could be a party and as to which indemnification or contribution
could be sought by such Indemnified Party under this Section 8.2, unless such
judgment, settlement or other termination includes, as an unconditional term
thereof, the giving by the claimant or plaintiff to such Indemnified Party of a
release, in form and substance reasonably satisfactory to the Indemnified Party,
from all liability in respect of such claim or litigation for which such
Indemnified Party would be entitled to indemnification hereunder and such
judgment or consent does not include a statement as to the admission of fault or
culpability on behalf of any Indemnified Party.

            (d) In the event the Indemnified Party has a claim against the
Indemnifying Party hereunder which does not involve a claim or demand being
asserted against or sought to be collected by a third party, the Indemnified
Party shall with reasonable promptness send a Claim Notice with respect to such
claim to the Indemnifying Party. If the Indemnifying Party does not notify the
Indemnified Party within the Notice Period that the Indemnifying Party disputes
such claim, the amount of such claim shall be conclusively deemed a liability of
the Indemnifying Party hereunder.

            (e) The Indemnified Party's failure to give reasonably prompt notice
to the Indemnifying Party of any actual, threatened or possible claim or demand
which may give rise to a right of indemnification hereunder shall not relieve
the Indemnifying Party of any liability which the Indemnifying Party may have to
the Indemnified Party unless the failure to give such notice materially and
adversely prejudices the Indemnifying Party.

      8.3 Survival of Representations, Warranties, etc. The respective
representations, warranties, and agreements made herein by or on behalf of the
Parties hereto shall remain in full force and effect, regardless of any
investigation made by or on behalf of any other Party to this Agreement or any
officer, director or employee of, or Person controlling or under common control
with, such Party and will survive delivery of and payment for any Restricted
Securities.

      8.4 Other.

            (a) Neither the Company nor any Purchaser shall have any obligation
under this Article VIII to indemnify any Person for lost profits or for
consequential, incidental, punitive or exemplary damages.

            (b) Any and all remedies set forth in this Agreement: (i) shall be
in addition to any and all other remedies the Purchasers or the Company may have
at law or in equity, (ii) shall be cumulative, and (iii) may be pursued
successively or concurrently as each of the Purchasers and the Company may
elect. The exercise of any remedy by any Purchaser or the Company shall not be
deemed an election of remedies or preclude any Purchaser or the Company,
respectively, from exercising any other remedies in the future.

respect to such obligations or the transactions contemplated by this Agreement.
Each Purchaser shall be entitled to protect and enforce its rights, including,

      SECTION 2. EXERCISE OF WARRANT.

            2.1 Procedure for Exercise of Warrant. To exercise this Warrant in
whole or in part (but not as to any fractional share of Common Stock), the
Holder shall deliver to the Company at its office referred to in Section 10
hereof at any time and from time to time during the Term of this Warrant: (i)
the Notice of Exercise in the form of Exhibit A attached hereto, (ii) cash, a
certified or official bank check payable to the order of the Company, or a wire
transfer of funds to the Company's account, in each case in the amount of the
Warrant Price for each share being purchased and any amount required to be paid
by the Holder on account of a transfer of a Warrant or Warrant Shares pursuant
to Section 3 hereof, and (iii) this Warrant.

            In the event of any exercise of the rights represented by this
Warrant, a certificate or certificates for the shares of Common Stock so
purchased, registered in the name of the Holder or, subject to compliance with
Section 6.2, such other name or names as may be designated by the Holder, shall
be delivered to the Holder hereof within a reasonable time, not exceeding three
Business Days, after the rights represented by this Warrant shall have been so

----------

      Price (as defined in the Standby Securities Purchase Agreement).

                                        2

<PAGE>

exercised; and, unless this Warrant has expired, a new Warrant representing the
number of shares with respect to which this Warrant shall not then have been
exercised shall also be issued to the Holder hereof within such time. The person
in whose name any certificate for shares of Common Stock is issued upon exercise
of this Warrant shall for all purposes be deemed to have become the holder of
record of such shares on the date on which the Holder shall have complied with
the conditions for exercise of this Warrant set forth above, irrespective of the
date of delivery of such certificate, except that, if the date of such
compliance is a date when the stock transfer books of the Company are closed,
such person shall be deemed to have become the holder of such shares at the
close of business on the next succeeding date on which the stock transfer books
are open.

            2.2 Transfer Restriction Legend. Each certificate for Warrant Shares
shall bear the following legend (and any additional legend required by (i) any
applicable state securities laws and (ii) any securities exchange upon which
such Warrant Shares may, at the time of such exercise, be listed) on the face
thereof unless at the time of exercise such Warrant Shares shall be registered
under the Securities Act:

            "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
            UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT")
            AND/OR QUALIFIED UNDER ANY STATE SECURITIES LAWS. SUCH SHARES MAY
            NOT be OFFERED OR sold or transferred EXCEPT (A) PURSUANT TO AN
            EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND
            REGISTRATION AND/OR QUALIFICATION UNDER APPLICABLE STATE SECURITIES
            LAWS, (B) IN A TRANSACTION WHICH IS EXEMPT FROM REGISTRATION UNDER
            THE SECURITIES ACT AND REGISTRATION AND/OR QUALIFICATION UNDER
            APPLICABLE STATE SECURITIES LAWS PROVIDED THAT AT THE ISSUER'S
            REQUEST, THE TRANSFEROR THEREOF SHALL HAVE DELIVERED TO THE ISSUER
            AN OPINION OF COUNSEL (WHICH OPINION SHALL BE IN FORM, SUBSTANCE AND
            SCOPE REASONABLY SATISFACTORY TO THE ISSUER FROM COUNSEL REASONABLY
            SATISFACTORY TO THE ISSUER) TO THE EFFECT THAT SUCH SECURITIES MAY
            BE SOLD OR TRANSFERRED PURSUANT TO AN EXEMPTION FROM SUCH
            REGISTRATION, OR (C) SUCH SECURITIES MAY BE SOLD PURSUANT TO RULE
            144 PROMULGATED UNDER THE SECURITIES ACT."

            Any certificate issued at any time in exchange or substitution for
any certificate bearing such legend shall also bear such legend unless, in the
opinion of counsel for the Holder thereof (which counsel shall be satisfactory
to the Company) the securities represented thereby are not, at such time,
required by law to bear such legend. The foregoing legend shall be removed from
the certificates representing any Warrant Shares, at the request of the Holder

                                       3

<PAGE>

thereof, at such time as they become eligible for resale pursuant to Rule
144(k) under the Securities Act or as they have been sold pursuant to a
registration statement declared effective by the Securities and Exchange
Commission or pursuant to Rule 144 under the Securities Act. At the request of
the Company, the Company shall have the right to receive an opinion of counsel
for the Holder, reasonably satisfactory to the Company, to the effect that the
transfer of the Warrant Shares is exempt from the registration requirements of
the Securities Act, prior to the removal of the legend if the request for
removal is being made pursuant to Rule 144 or Rule 144(k) under the Securities
Act.

      SECTION 3. COVENANTS AS TO COMMON STOCK. The Company shall at all times
reserve and keep available out of its authorized but unissued Common Stock (or
out of shares of Common Stock held in its treasury) solely for the purpose of
issuance upon the exercise of this Warrant, the maximum number of Warrant Shares
issuable upon the exercise of this Warrant. The Company covenants and agrees
that all shares of Common Stock that may be issued upon the exercise of the
rights represented by this Warrant shall, upon issuance, be validly issued,
fully paid and nonassessable, and free from all taxes, liens, preemptive rights
and charges with respect to the issue thereof. The Company shall take all such
actions as may be necessary to ensure that all such Warrant Shares may be so
issued without violation by the Company of any applicable law or governmental
regulation or any requirements of any domestic securities exchange or quotation
system upon which shares of Common Stock or other securities constituting
Warrant Shares may be listed or quoted (except for official notice of issuance
which shall be immediately delivered by the Company upon each such issuance).
The Company further covenants and agrees that it shall pay when due and payable
any and all federal and state documentary or stamp taxes (other than federal or
state income taxes) which may be payable in respect of the issue of this Warrant
or any Common Stock or certificates therefor issuable upon the exercise of this
Warrant, except that, if Warrant Shares or new Warrants shall be registered in a
name or names other than the name of the Holder, funds sufficient to pay all
transfer taxes payable as a result of such transfer shall be paid by the Holder
at the time of delivery of the Notice of Exercise.

      SECTION 4. ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment of the
Warrant Price as provided in Section 5(a), Section 5(b), Section 5(c) or Section
5(f), the number of Warrant Shares shall be changed to the number determined by
multiplying the Warrant Price in effect immediately prior to such adjustment by
the number of Warrant Shares purchasable immediately prior to such adjustment
and dividing the product thereof by the Warrant Price resulting from such
adjustment.

      SECTION 5. ADJUSTMENT. The Warrant Price and terms of the Warrant shall be
subject to adjustment from time to time as follows:

            (a) If, at any time during the Term of this Warrant, the Company
   shall make or issue, a dividend or other distribution payable in additional
   shares of Common Stock, then and in each such event the Warrant Price then in
   effect immediately before such event shall be decreased as of the time of
   such issuance by multiplying the Warrant Price then in effect by a fraction:

                                        4

<PAGE>

                        (1) the numerator of which shall be the total number of
shares of Common Stock issued and outstanding immediately prior to the time of
such issuance, and

                        (2) the denominator of which shall be the total number
of shares of Common Stock issued and outstanding immediately prior to the time
of such issuance plus the number of shares of Common Stock issuable in payment
of such dividend or distribution.

            (b) If, at any time during the Term of this Warrant, the number of
   shares of Common Stock outstanding is increased by a subdivision or split-up
   of shares of Common Stock, then, immediately after the date fixed for the
   determination of holders of Common Stock entitled to receive shares in such
   subdivision or split-up, the Warrant Price in effect immediately before the
   subdivision or split-up shall be appropriately decreased so that the number
   of shares of Common Stock issuable upon the exercise hereof shall be
   increased in proportion to such increase in outstanding shares.

            (c) If, at any time during the Term of this Warrant, the number of
   shares of Common Stock outstanding is decreased by a combination of the
   outstanding shares of Common Stock or reverse stock split, then, immediately
   after the effective date for such combination, the Warrant Price in effect
   immediately prior to such combination or reverse stock split shall be
   appropriately increased so that the number of shares of Common Stock issuable
   upon the exercise hereof shall be decreased in proportion to such decrease in
   outstanding shares.

            (d) If, at any time during the Term of this Warrant, the Company
   shall make or issue, or fix a record date for the determination of holders of
   Common Stock entitled to receive, a dividend or other distribution payable in
   securities of the Company (other than shares of Common Stock) or in cash or
   other property (other than dividends or distributions for which an adjustment
   is made pursuant to other provisions of this Section 5 or regular cash
   dividends paid out of earnings or earned surplus, determined in accordance
   with generally accepted accounting principles), then and in each such event
   provision shall be made so that the Holder shall receive upon the exercise
   hereof, in addition to the number of shares of Common Stock issuable
   hereunder, the kind and amount of securities of the Company, cash or other
   property which the Holder would have been entitled to receive had this
   Warrant been exercised on the effective date fixed for the determination of
   holders of Common Stock entitled to receive a dividend or distribution in
   such event and had the Holder thereafter, during the period from such date to
   and including the exercise date, retained any such securities receivable
   during such period, giving application to all adjustments called for during
   such period under this Section 5 with respect to the rights of the Holder.

            (e) In the case of any proposed consolidation or merger of the
   Company with another entity, or the proposed sale of all or substantially all
   of its assets to another person or entity, or any proposed consolidation,
   reorganization, recapitalization, or reclassification of the capital stock of
   the Company or other transaction, then, as a condition of such consolidation,
   merger, sale, consolidation, reorganization, recapitalization,
   reclassification or other transaction, the Company shall give 30 days' prior
   written notice thereof to the Holder

                                        5

<PAGE>

   hereof and lawful and adequate provision shall be made whereby the Holder
   shall thereafter have the right to receive upon the basis and upon the terms
   and conditions specified herein, in lieu of the Warrant Shares immediately
   theretofore purchasable hereunder, such shares of stock, securities, cash or
   assets as may (by virtue of such consolidation, merger, sale, consolidation,
   reorganization, recapitalization, reclassification or other transaction) be
   issued or payable with respect to or in exchange for the number of Warrant
   Shares purchasable hereunder immediately before such consolidation, merger,
   sale, reorganization, recapitalization, reclassification or other
   transaction. In any such case appropriate provision shall be made with
   respect to the rights and interests of the Holder to the end that the
   provisions hereof shall thereafter be applicable as nearly as may be
   practicable, in relation to any shares of stock, securities, cash or assets
   thereafter deliverable upon the exercise of this Warrant. Notwithstanding the
   foregoing sentences, if (x) there shall occur any consolidation, merger,
   sale, consolidation, reorganization, recapitalization or other transaction in
   which the Common Stock is converted into or exchanged for anything other than
   solely equity securities, and (y) the common stock of the acquiring or
   surviving company (which shall be understood to mean the ultimate parent of
   such company, if such company is not publicly traded and its ultimate parent
   is publicly traded) is publicly traded, then, as part of such consolidation,
   merger, sale, consolidation, reorganization, recapitalization,
   reclassification or other transaction, (i) the Holder shall have the right
   thereafter to receive upon the exercise hereof such number of shares of
   common stock of the acquiring or surviving company as is determined by
   multiplying (A) the number of shares of Common Stock subject to this Warrant
   immediately prior to such consolidation, merger, sale, consolidation,
   reorganization, recapitalization, reclassification or other transaction by
   (B) a fraction, the numerator of which is the Fair Market Value (as defined
   below) per share of Common Stock as of the effective date of such
   consolidation, merger, sale, consolidation, reorganization, recapitalization,
   reclassification or other transaction, as determined pursuant to Section 7,
   and the denominator of which is the fair market value per share of common
   stock of the acquiring or surviving company as of the effective date of such
   transaction, as determined in good faith by the Board of Directors of the
   Company (using the principles set forth in Section 7 to the extent
   applicable), and (ii) the exercise price per share of common stock of the
   acquiring or surviving company shall be the Warrant Price divided by the
   fraction referred to in clause (B) above. The Company shall not effect any
   such consolidation, merger, sale, reorganization, recapitalization,
   reclassification or other transaction unless, prior to the consummation
   thereof, the successor entity (if other than the Company) resulting from such
   consolidation, merger, sale, reorganization, recapitalization,
   reclassification or other transaction (including a purchaser of all or
   substantially all the Company's assets) assumes by written instrument the
   obligation to deliver to each Holder of Warrants such shares of stock,
   securities, cash or assets as, in accordance with the foregoing provisions,
   such Holder may be entitled to acquire upon exercise of Warrants.

            (f) If at any time the Company shall issue or sell any Common Stock
   (other than Common Stock issued (a) pursuant to the Company's existing or
   future stock option plans or pursuant to any other existing or future Common
   Stock related director or employee compensation plan of the Company approved
   by the board of directors of the Company (the "BOARD OF DIRECTORS"), (b) as
   consideration for the acquisition of a business or of assets, (c) to the
   Company's joint venture partners in exchange for interests in the relevant
   joint venture, (d) upon conversion of any shares of any series of preferred
   stock or as the payment

                                        6

<PAGE>

   of a dividend with respect to any series of preferred stock outstanding on
   the date hereof or the issuance of which caused an adjustment under the other
   provisions of this Section 5 or (e) upon the exercise or conversion of any
   security the issuance of which caused an adjustment under the other
   provisions of this Section 5 for a consideration per share less than the
   Warrant Price then in effect, or shall issue any options, rights, warrants or
   other securities convertible into or exercisable or exchangeable for Common
   Stock (other than such securities paid as dividends on any class of preferred
   stock outstanding on the date hereof or the issuance of which caused an
   adjustment under the other provisions of this Section 5) having a conversion,
   exercise or exchange price, together with the issue price of such securities,
   per share of Common Stock less than the Warrant Price then in effect, the
   Warrant Price to be in effect after such issuance or sale shall be determined
   by multiplying the Warrant Price in effect immediately prior to such issuance
   or sale by a fraction, (i) the denominator of which shall be the sum of (w)
   the number of shares of Common Stock outstanding immediately prior to such
   issuance or sale plus (x) the number of additional shares of Common Stock to
   be issued or sold (or, in the case of any options, rights, warrants or other
   convertible, exercisable or exchangeable securities, issued on conversion,
   exercise or exchange), and (ii) the numerator of which shall be the sum of
   (y) the number of shares of Common Stock outstanding immediately prior to
   such issuance and sale plus (z) the number of shares of Common Stock which
   the aggregate consideration received by the Company for the total number of
   additional shares of Common Stock so issued or sold (or issuable on
   conversion, exercise or exchange) would purchase at the Warrant Price in
   effect on the date of such issuance or sale. In case any portion of the
   consideration to be received by the Company shall be in a form other than
   cash, the fair market value (determined in accordance with the principles set
   forth in Section 7 to the extent applicable) of such non-cash consideration
   shall be utilized in the foregoing computation. Such adjustment shall be made
   successively whenever any such issuance or sale is made, and shall become
   effective immediately after such issuance or sale. If all the Common Stock
   deliverable upon exercise, conversion or exchange of securities convertible
   into Common Stock have not been issued when such securities are no longer
   outstanding, then the Warrant Price shall promptly be readjusted to the
   Warrant Price which would then be in effect had the adjustment upon the
   issuance of such securities been made on the basis of the actual number of
   Common Stock issued upon conversion, exercise or exchange of such securities.

            (g) Whenever the Warrant Price shall be adjusted as provided in this
   Section 5, the Company shall promptly prepare a statement showing the facts
   requiring such adjustment and the Warrant Price and number of Warrant Shares
   that shall be in effect after such adjustment, setting forth in reasonable
   detail and certifying the calculation of such adjustment. The Company shall
   cause a copy of such statement to be sent by mail, first class postage
   prepaid, to each Holder at its, his or her address appearing on the Company's
   records. The Company shall, as promptly as reasonably practicable after the
   written request at any time of the Holder (but in any event not later than 10
   days thereafter), furnish or cause to be furnished to the Holder a
   certificate setting forth (i) the Warrant Price then in effect and (ii) the
   number of shares of Common Stock and the amount, if any, of other securities,
   cash or property which then would be received upon the exercise of this
   Warrant.

            (h) Adjustments made pursuant to this Section 5 shall be made on the
   date such dividend, subdivision, split-up, reverse stock split, combination,
   distribution, issuance,

                                        7

   sale, consolidation, reorganization, recapitalization, reclassification or
   other transaction, as the case may be, is made, and shall become effective at
   the close of business on the day such event becomes effective.

      SECTION 6. OWNERSHIP.

            6.1 Ownership of Warrant. The Company may deem and treat the person
   in whose name this Warrant is registered as the holder and owner hereof
   (notwithstanding any notations of ownership or writing hereon made by anyone
   other than the Company) for all purposes and shall not be affected by any
   notice to the contrary until presentation of this Warrant for registration of
   transfer as provided in this Section 6.

            6.2 Transfer and Replacement.

            (a) No Holder shall Transfer this Warrant other than (i) a Transfer
   to one or more of its Affiliates or (ii) if the Company first shall have been
   furnished with an opinion of legal counsel, reasonably satisfactory to the
   Company, to the effect that such Transfer is exempt from the registration
   requirements of the Securities Act. Notwithstanding the foregoing, no
   registration or opinion of counsel shall be required for, and a Transfer
   shall be permitted in the event of, a Transfer by a Holder which is a
   partnership to a partner of such partnership or a retired partner of such
   partnership or to the estate of any such partner or retired partner, or a
   Transfer by a Holder which is a limited liability company to a member of such
   limited liability company or a retired member or to the estate of any such
   member or retired member, provided that the transferee in each case agrees in
   writing to be subject to the terms of this Section 6. Any attempt to Transfer
   this Warrant other than in accordance with this Section 6 shall be null and
   void and no right, title or interest in or to such Warrant shall be
   Transferred to the purported transferee, buyer, donee, assignee or
   encumbrance holder. The Company will not give, and will not permit the
   Company's transfer agent to give, any effect to such attempted Transfer in
   its stock records.

            (b) Subject to Section 6.2(a), this Warrant and all rights hereunder
   are transferable in whole or in part upon the books of the Company by the
   Holder hereof in person or by duly authorized attorney, together with a
   properly executed Assignment (in the form of Exhibit B or Exhibit C hereto,
   as the case may be) and a new Warrant or Warrants, of the same tenor as this
   Warrant but registered in the name of the transferee or transferees (and in
   the name of the Holder, if a partial transfer is effected) shall be promptly
   made and delivered by the Company upon surrender of this Warrant duly
   endorsed, at the office of the Company referred to in Section 9 hereof. Upon
   receipt by the Company of evidence reasonably satisfactory to it of the loss,
   theft or destruction, and, in such case, of indemnity or security reasonably
   satisfactory to it, and upon surrender of this Warrant if mutilated, the
   Company shall promptly make and deliver a new Warrant of like tenor, in lieu
   of this Warrant. This Warrant shall be promptly cancelled by the Company upon
   the surrender hereof in connection with any transfer or replacement. Except
   as otherwise provided above, in the case of the loss, theft or destruction of
   a Warrant, the Company shall pay all expenses, taxes and other charges
   payable in connection with any transfer or replacement of this Warrant, other
   than documentary or stamp taxes (if any) payable in connection with a
   transfer of this Warrant, which shall be payable by the Holder. The Holder
   shall not transfer this Warrant and the rights hereunder except in compliance
   with federal and state securities laws.

                                        8

      SECTION 7. FRACTIONAL SHARES. Fractional shares shall not be issued upon
the exercise of this Warrant but in any case where the Holder would, except for
the provisions of this Section 7, be entitled under the terms hereof to receive
a fractional share upon the complete exercise of this Warrant, the Company
shall, upon the exercise of this Warrant for the largest number of whole shares
then called for, pay a sum in cash equal to the excess of the Fair Market Value
of such fractional share over the Warrant Price for such fractional share on the
exercise date.

            (a) The Fair Market Value per share of Common Stock shall be
   determined as follows:

                  (i) If the Common Stock is listed on a national securities
exchange, the Nasdaq National Market or another nationally recognized trading
system as of the exercise date, the Fair Market Value per share of Common Stock
shall be deemed to be the average of the high and low reported sale prices per
share of Common Stock thereon on the trading day immediately preceding the
effective date or the exercise date, as applicable (provided that if no such
price is reported on such day, the Fair Market Value per share of Common Stock
shall be determined pursuant to clause (ii)).

                  (ii) If the Common Stock is not listed on a national
securities exchange, the Nasdaq National Market or another nationally recognized
trading system as of the effective date or the exercise date, as applicable, the
Fair Market Value per share of Common Stock shall be deemed to be the amount
most recently determined by the Board to represent the fair market value per
share of the Common Stock (including without limitation a determination for
purposes of granting Common Stock options or issuing Common Stock under any
plan, agreement or arrangement with employees of the Company); and, upon request
of the Holder, the Board (or a representative thereof) shall, as promptly as
reasonably practicable but in any event not later than 3 Business Days after
such request, notify the Holder of the Fair Market Value per share of Common
Stock and furnish the Holder with reasonable documentation of the Board's
determination of such Fair Market Value. Notwithstanding the foregoing, if the
Board has not made such a determination within the three-month period prior to
the exercise date, then (A) the Board shall make, and shall provide or cause to
be provided to the Holder notice of, a determination of the Fair Market Value
per share of the Common Stock within 15 days of a request by the Holder that it
do so, and (B) payment in cash with respect to any fractional share as required
by Section 7 hereof shall be delayed until such determination is made and notice
thereof is provided to the Holder (it being understood that this shall not
prevent the Holder, at its option, from exercising the Warrant prior to such
determination).

      SECTION 8. SPECIAL ARRANGEMENTS OF THE COMPANY. The Company covenants and
agrees that during the Term of this Warrant, unless otherwise approved by the
Holder:

            8.1 Certain Actions. The Company shall not amend its charter to
eliminate as an authorized class of capital stock that class denominated as
"Common Stock" on the date hereof. The Company shall not by any action avoid or
seek to avoid the observance

                                        9

<PAGE>

or performance of any terms of this Warrant or impair or diminish its value, but
shall at all times in good faith assist in the carrying out of all such terms of
Warrant. Without limiting the generality of the foregoing, the Company shall
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.

            8.2 Shall Bind Successors. This Warrant and the rights evidenced
hereby shall be binding upon the Company and its successors and assigns and
shall inure to the benefit of the Holder and its permitted assigns to the extent
permitted by Section 6.2.

            8.3 No Exercise Interference; Par Value. Other than in accordance
with Section 6.2, the Company shall not close its books against the transfer of
this Warrant or of any Warrant Shares issued or issuable upon the exercise of
this Warrant in any manner which interferes with the timely exercise of this
Warrant. The Company shall from time to time take all such action as may be
necessary to assure that the par value per share of the unissued Warrant Shares
acquirable upon exercise of this Warrant is at all times equal to or less than
the Warrant Price then in effect.

            8.4 Notices of Certain Actions. The Company shall give written
notice to the Holder in the event (A) the Company closes its books or takes a
record (1) with respect to any dividend or distribution upon the Common Stock,
or for the purpose of entitling or enabling any stockholder to receive any other
right, or (2) with respect to any pro rata subscription offer to holders of
Common Stock, or (B) of any recapitalization, reorganization, reclassification,
consolidation, merger, dissolution, liquidation or sale of all or substantially
all of the Company's assets or other transaction which is effected in such a way
that holders of Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities, cash or assets with respect to or in
exchange for Common Stock. Such notice shall be sent at least ten days prior to
the record date or effective date for the event specified in such notice.

      SECTION 9. NOTICES. Any notice or other document required or permitted to
be given or delivered to the Holder shall be delivered at, or sent by certified
or registered mail to, the Holder at such address as shall have been furnished
to the Company in writing by the Holder. Any notice or other document required
or permitted to be given or delivered to the Company shall be delivered at, or
sent by certified or registered mail to, the Company at its address for notices
set forth on the signature page hereto or to such other address as shall have
been furnished in writing to the Holder by the Company. Any notice so addressed
and mailed by registered or certified mail shall be deemed to be given when so
mailed. Any notice so addressed and otherwise delivered shall be deemed to be
given when actually received by the addressee.

      SECTION 10. NO RIGHTS AS STOCKHOLDER; LIMITATION OF LIABILITY. This
Warrant shall not entitle the Holder to any of the rights of a stockholder of
the Company (including, without limitation, any preemption rights, voting rights
or rights to dividends) except upon exercise in accordance with the terms
hereof. Notwithstanding the foregoing, in the event (i) the Company effects a
split of the Common Stock by means of a stock dividend and the Warrant Price of
and the number of Warrant Shares are adjusted as of the date of the distribution
of the dividend (rather than as of the record date for such dividend), and (ii)
the Holder exercises this Warrant

                                       10

<PAGE>

between the record date and the distribution date for such stock dividend, the
Holder shall be entitled to receive, on the distribution date, the stock
dividend with respect to the shares of Common Stock acquired upon such exercise,
notwithstanding the fact that such shares were not outstanding as of the close
of business on the record date for such stock dividend. No provision hereof, in
the absence of affirmative action by the Holder to purchase shares of Common
Stock, and no mere enumeration herein of the rights or privileges of the Holder,
shall give rise to any liability of the Holder for the Warrant Price hereunder
or as a stockholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

      SECTION 11. GOVERNING LAW. THE VALIDITY, INTERPRETATION, AND ENFORCEMENT
OF THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF DELAWARE WITHOUT GIVING EFFECT TO THE CONFLICT OF LAW PRINCIPLES
THEREOF.

      SECTION 12. WARRANT REGISTER. The Company shall maintain at its principal
executive offices books for the registration and the registration of transfer of
Warrants. The Holder may change its address as shown on the warrant register by
written notice to the Company requesting such change.

      SECTION 13. AMENDMENTS. This Warrant and any provision hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the Holder and the Company. The headings in this Warrant are for
purposes of reference only and shall not affect the meaning or construction of
any of the provisions hereof.

2.    RESALE REGISTRATION.

            (a) Registration Requirement.

                  Subject to the last sentence of this paragraph, the Company
shall prepare promptly and file with the Commission a Resale Registration
Statement meeting the requirements of the Securities Act within five (5)
Business Days following the Closing under the Purchase Agreement, and will use
its best efforts to cause the Resale Registration Statement to be declared
effective by the Commission as soon as practicable thereafter and in any event
not later than sixty (60) days after such filing. The Company's obligations to
file a Resale Registration Statement and to have it declared effective within
the time periods set forth in the first sentence of this Section 2(a) shall be
subject to the Company's right to deliver to the Holders a Delay Notice pursuant
to Section 2(e) hereof.

                  If a Resale Registration Statement is not filed with the
Commission within five (5) Business Days following the Closing under the
Purchase Agreement (subject to any bona fide Delay Period), the Company will pay
to each Holder, as liquidated damages and not as a penalty, an amount equal to
1.0% of the aggregate purchase price for the Unsubscribed Shares paid by such
Holder pursuant to Section 1.3 of the Purchase Agreement for each month or part
thereof that such Resale Registration Statement has not been filed, payable in
monthly installments. If the Resale Registration Statement is not declared
effective by the Commission within 60 days after it is filed with the Commission
(subject to any bona fide Delay Period), the

                                       4
<PAGE>

Company will pay to each Holder, as liquidated damages and not as a penalty, an
amount equal to 1.0% of the aggregate purchase price for the Unsubscribed Shares
paid by such Holder pursuant to Section 1.3 of the Purchase Agreement for each
month or part thereof that such Resale Registration Statement has not been
declared effective, payable in monthly installments. The payment of liquidated
damages pursuant to this paragraph shall be made by the Company, at its option,
either in cash or in Liquidated Damages Warrants having a value (such value to
be determined as set forth below) equal to such liquidated damages. Such
Liquidated Damages Warrants shall contain the same terms as the Standby
Commitment Fee Warrants except that they shall have an exercise period of one
year from the date of actual issuance, and they shall have an exercise price (x)
with respect to the first installment of Liquidated Damages Warrants, equal to
the Average Share Price (as defined in the Purchase Agreement) on the date on
which the Company first becomes obligated to pay the liquidated damages and (y)
with respect to any subsequent installment of Liquidated Damages Warrants, on
the first Business Day of the month period for which such installment is
issuable. The value of such Liquidated Damages Warrants shall be equal to their
Black Scholes Warrant Value. Liquidated damages shall be deemed to commence
accruing on the day on which the event triggering such liquidated damages
occurs. The liquidated damages to be paid to the Holders pursuant to this
Section 2(a) shall cease to accrue (i) with respect to the liquidated damages
for failure to have the Resale Registration Statement filed with the Commission
on or prior to the fifth Business Day following the Closing, on the day that the
Resale Registration Statement has been filed with the Commission or (ii) with
respect to the liquidated damages for failure to have the Resale Registration
Statement declared effective on or prior to the sixtieth (60th) day after it is
filed with the Commission, on the day that the Resale Registration Statement has
been declared effective by the Commission. The parties hereto agree that the
liquidated damages provided for in this Section 2(a) constitute a reasonable
estimate of the damages that will be suffered by the Holders by reason of the
failure of the Resale Registration Statement to be filed and/or to be declared
effective, as the case may be, in accordance with this Agreement.

            (b) Effectiveness Requirement.

                  The Company agrees to use its best efforts to keep the Resale
Registration Statement continuously effective and the Prospectus usable for
resales for a period commencing on the date that such Resale Registration
Statement is initially declared effective by the Commission and terminating on
the date when all of the Registrable Securities covered by such Resale
Registration Statement have been sold pursuant to such Resale Registration
Statement or have ceased to be Registrable Securities (the "EFFECTIVENESS
PERIOD"); provided, however, the Company is permitted to suspend sales of the
Registrable Securities during any Delay Period.

                  After the Resale Registration Statement has been declared
effective by the Commission, if at any time the Resale Registration Statement or
the Prospectus thereunder cannot be used for the resale of the Registrable
Securities for any reason (including without limitation by reason of a stop
order or the Company's failure to update the Resale Registration Statement but
subject to any bona fide Delay Period), then, subject to subsection (e) below,
the Company will pay to each Holder, as liquidated damages and not as a penalty,
an amount equal to 1.0% of the aggregate purchase price for the Unsubscribed
Shares paid by such Holder pursuant to Section 1.3 of the Purchase Agreement for
each month or part thereof that such Resale Registration Statement cannot be
used for the resale of the Registrable Securities, payable

                                       5
<PAGE>

in monthly installments. The payment of liquidated damages pursuant to this
paragraph shall be made by the Company, at its option, either in cash or in
Liquidated Damages Warrants having a value (such value to be determined as set
forth below) equal to such liquidated damages. Such Liquidated Damages Warrants
shall contain the same terms as the Standby Commitment Fee Warrants except that
they shall have an exercise period of one year from the date of actual issuance,
and they shall have an exercise price (x) with respect to the first installment
of Liquidated Damages Warrants, equal to the Average Share Price (as defined in
the Purchase Agreement) on the date on which the Company first becomes obligated
to pay the liquidated damages and (y) with respect to any subsequent installment
of Liquidated Damages Warrants, on the first Business Day of the month period
for which such installment is issuable. The value of such Liquidated Damages
Warrants shall be equal to their Black Scholes Warrant Value. Liquidated damages
shall be deemed to commence accruing on the day on which the event triggering
such liquidated damages occurs. The liquidated damages to be paid to the Holders
pursuant to this Section 2(b) shall cease to accrue on the day the Holders have
received notice from the Company regarding the reinstatement of effectiveness of
the Resale Registration Statement. The parties hereto agree that the liquidated
damages provided for in this Section 2(b) constitute a reasonable estimate of
the damages that will be suffered by the Holders by reason of the failure of the
Resale Registration Statement to remain effective in accordance with this
Agreement.

            (c) Warrant Resale Registration Statement.

                  Subject to the last sentence of this paragraph, if the Company
is not able to register the resale of the Warrant Common Stock issuable upon
exercise of the Liquidated Damages Warrants (the "REGISTRABLE LIQUIDATED DAMAGES
WARRANT SECURITIES") pursuant to the Resale Registration Statement, the Company
shall prepare promptly and file with the Commission a Warrant Resale
Registration Statement meeting the requirements of the Securities Act within ten
(10) Business Days following the issuance of any such Liquidated Damages
Warrants, and will use its best efforts to cause the Warrant Resale Registration
Statement to be declared effective by the Commission as soon as practicable
thereafter and in any event not later than sixty (60) days after such filing.
The Company's obligations to file a Warrant Resale Registration Statement and to
have it declared effective within the time periods set forth in the first
sentence of this Section 2(c) shall be subject to the Company's right to deliver
to the Holders a Delay Notice pursuant to Section 2(e) hereof.

                  If a Warrant Resale Registration Statement is not filed with
the Commission within ten (10) Business Days following the issuance of any such
Liquidated Damages Warrants (subject to any bona fide Delay Period), the Company
will pay to each Holder, as liquidated damages and not as a penalty, an amount
equal to 1.0% of the liquidated damages relating to such Liquidated Damages
Warrants for each month or part thereof that such Warrant Resale Registration
Statement has not been filed, payable in monthly installments. If the Warrant
Resale Registration Statement is not declared effective by the Commission within
60 days after it is filed with the Commission (subject to any bona fide Delay
Period), the Company will pay to each Holder, as liquidated damages and not as a
penalty, an amount equal to 1.0% of the liquidated damages relating to such
Liquidated Damages Warrants for each month or part thereof that such Warrant
Resale Registration Statement has not been declared effective, payable in
monthly installments. The payment of liquidated damages pursuant to this
paragraph shall be

                                       6
<PAGE>

made by the Company, at its option, either in cash or in Liquidated Damages
Warrants having a value (such value to be determined as set forth below) equal
to such liquidated damages. Such Liquidated Damages Warrants shall contain the
same terms as the Standby Commitment Fee Warrants except that they shall have an
exercise period of one year from the date of actual issuance, and they shall
have an exercise price (x) with respect to the first installment of Liquidated
Damages Warrants, equal to the Average Share Price (as defined in the Purchase
Agreement) on the date on which the Company first becomes obligated to pay the
liquidated damages and (y) with respect to any subsequent installment of
Liquidated Damages Warrants, on the first Business Day of the month period for
which such installment is issuable. The value of such Liquidated Damages
Warrants shall be equal to their Black Scholes Warrant Value. Liquidated damages
shall be deemed to commence accruing on the day on which the event triggering
such liquidated damages occurs. The liquidated damages to be paid to the Holders
pursuant to this Section 2(c) shall cease to accrue (i) with respect to the
liquidated damages for failure to have the Warrant Resale Registration Statement
filed with the Commission on or prior to the tenth Business Day following the
Closing, on the day that the Warrant Resale Registration Statement has been
filed with the Commission or (ii) with respect to the liquidated damages for
failure to have the Warrant Resale Registration Statement declared effective on
or prior to the sixtieth (60th) day after it is filed with the Commission, on
the day that the Warrant Resale Registration Statement has been declared
effective by the Commission. The parties hereto agree that the liquidated
damages provided for in this Section 2(c) constitute a reasonable estimate of
the damages that will be suffered by the Holders by reason of the failure of the
Warrant Resale Registration Statement to be filed and/or to be declared
effective, as the case may be, in accordance with this Agreement.

            (d) Warrant Resale Registration Statement Effectiveness Requirement.

                  The Company agrees to use its best efforts to keep the Warrant
Resale Registration Statement continuously effective and the Prospectus usable
for resales for a period commencing on the date that such Warrant Resale
Registration Statement is initially declared effective by the Commission and
terminating on the date when all of the Registrable Liquidated Damages Warrant
Securities covered by such Warrant Resale Registration Statement have been sold
pursuant to such Warrant Resale Registration Statement or have ceased to be
Registrable Liquidated Damages Warrant Securities; provided, however, the
Company is permitted to suspend sales of the Registrable Liquidated Damages
Warrant Securities during any Delay Period.

                  After the Warrant Resale Registration Statement has been
declared effective by the Commission, if at any time the Warrant Resale
Registration Statement or the Prospectus thereunder cannot be used for the
resale of the Registrable Liquidated Damages Warrant Securities for any reason
(including without limitation by reason of a stop order or the Company's failure
to update the Warrant Resale Registration Statement but subject to any bona fide
Delay Period), then, subject to subsection (e) below, the Company will pay to
each Holder, as liquidated damages and not as a penalty, an amount equal to 1.0%
of the liquidated damages relating to the related Liquidated Damages Warrants
for each month or part thereof that such Warrant Resale Registration Statement
cannot be used for the resale of the Registrable Liquidated Damages Warrant
Securities, payable in monthly installments. The payment of liquidated damages
pursuant to this paragraph shall be made by the Company, at its option,

                                       7
<PAGE>

either in cash or in Liquidated Damages Warrants having a value (such value to
be determined as set forth below) equal to such liquidated damages. Such
Liquidated Damages Warrants shall contain the same terms as the Standby
Commitment Fee Warrants except that they shall have an exercise period of one
year from the date of actual issuance, and they shall have an exercise price (x)
with respect to the first installment of Liquidated Damages Warrants, equal to
the Average Share Price (as defined in the Purchase Agreement) on the date on
which the Company first becomes obligated to pay the liquidated damages and (y)
with respect to any subsequent installment of Liquidated Damages Warrants, on
the first Business Day of the month period for which such installment is
issuable. The value of such Liquidated Damages Warrants shall be equal to their
Black Scholes Warrant Value. Liquidated damages shall be deemed to commence
accruing on the day on which the event triggering such liquidated damages
occurs. The liquidated damages to be paid to the Holders pursuant to this
Section 2(d) shall cease to accrue on the day the Holders have received notice
from the Company regarding the reinstatement of effectiveness of the Warrant
Resale Registration Statement. The parties hereto agree that the liquidated
damages provided for in this Section 2(d) constitute a reasonable estimate of
the damages that will be suffered by the Holders by reason of the failure of the
Warrant Resale Registration Statement to remain effective in accordance with
this Agreement.

            (e) Delay Period.

                  The term "DELAY PERIOD" means, with respect to any obligation
to file any Resale Registration Statement or any Warrant Resale Registration
Statement or to keep any Resale Registration Statement, Warrant Resale
Registration Statement or Prospectus usable for resales pursuant to this Section
2, the shortest period of time determined in good faith by the Company's Board
of Directors to be necessary when there exist circumstances relating to a
material pending development, including, but not limited to, a pending or
contemplated material acquisition or merger or other material transaction or
event, which would require additional disclosure by the Company in such Resale
Registration Statement, Warrant Resale Registration Statement or Prospectus of
previously non-public material information which the Company determines in good
faith upon the advice of counsel that it has a bona fide business purpose for
keeping confidential and non-public and the non-disclosure of which in such
Resale Registration Statement, Warrant Resale Registration Statement or
Prospectus might cause such Resale Registration Statement, Warrant Resale
Registration Statement or Prospectus to fail to comply with applicable
disclosure requirements or if the Company becomes ineligible to use the
registration form on which the Resale Registration Statement or Warrant Resale
Registration Statement is filed and declared effective (such circumstances,
"DELAY CIRCUMSTANCES"). A Delay Period shall commence on and include the date
that the Company gives written notice (a "DELAY NOTICE") to the Holders that the
Prospectus is no longer usable as a result of such Delay Circumstances and shall
end on the date when the Holders are advised in writing by the Company that the
current Delay Period has terminated (it being understood that the Company shall
give such notice to all Holders promptly upon making the determination that the
Delay Period has ended). If as a result of the circumstances giving rise to the
Delay Period the Prospectus included in the Resale Registration Statement or the
Warrant Resale Registration Statement has been amended to comply with the
requirements of the Securities Act, the Company shall enclose such revised
Prospectus with the notice to the Holders advising them that the Delay Period
has terminated. Notwithstanding anything herein to the contrary the Company is
only entitled to three (3) Delay Periods having durations of not more than
thirty (30) days each

                                       8
<PAGE>

during any consecutive 12 month period, and not to exceed more than ninety (90)
days in the aggregate in any consecutive 12 month period. A Delay Period may not
commence if a prior Delay Period has terminated within the previous 30 days or
if three Delay Periods have occurred during the consecutive 12 month period
ending on the date that the Company gives notice that a Delay Period has
commenced. The Company covenants and agrees that it will not deliver a Delay
Notice with respect to a Delay Period unless the Company's employees, officers
and directors and their affiliates are also prohibited by the Company for the
duration of the Delay Period from effecting any public sales of shares of Common
Stock beneficially owned by them.

                  If at any time the Company breaches the terms of this Section
2(e) with respect to the number of Delay Periods in any 12 month period or if
the duration of any Delay Period exceeds 30 days, then, the Company will pay to
each Holder, as liquidated damages and not as a penalty, an amount equal to 1.0%
of the aggregate purchase price for the Unsubscribed Shares paid by such Holder
pursuant to Section 1.3 of the Purchase Agreement for each month or part thereof
that the Company is in violation of this Section 2(e), payable in monthly
installments. The payment of liquidated damages pursuant to this paragraph shall
be made by the Company, at its option, either in cash or in Liquidated Damages
Warrants having a value (such value to be determined as set forth below) equal
to such liquidated damages. Such Liquidated Damages Warrants shall contain the
same terms as the Standby Commitment Fee Warrants except that they shall have an
exercise period of one year from the date of actual issuance, and they shall
have an exercise price (x) with respect to the first installment of Liquidated
Damages Warrants, equal to the Average Share Price (as defined in the Purchase
Agreement) on the date on which the Company first becomes obligated to pay the
liquidated damages and (y) with respect to any subsequent installment of
Liquidated Damages Warrants, on the first Business Day of the month period for
which such installment is issuable. The value of such Liquidated Damages
Warrants shall be equal to their Black Scholes Warrant Value. Liquidated damages
shall be deemed to commence accruing on the day on which the event triggering
such liquidated damages occurs. The liquidated damages to be paid to the Holders
pursuant to this Section 2(e) shall cease to accrue on the day such Delay Period
that causes the Company to breach the terms of this Section 2(e) terminates. The
parties hereto agree that the liquidated damages provided for in this Section
2(e) constitute a reasonable estimate of the damages that will be suffered by
the Holders by reason of the breach by the Company of the terms of this Section
2(e).

            (f) Notice.

                  The Company will, in the event a Registration Statement is
declared effective, notify each such Holder as promptly as practicable, and in
any event no later than the next Business Day, when such Registration Statement
has become effective and take such other actions as are required to permit
unrestricted resales of the Registrable Securities or Registrable Liquidated
Damages Warrant Securities, including providing to each Holder a reasonable
number of copies of the Prospectus which is a part of such Registration
Statement as is requested by such Holder. The Company further agrees to
supplement or amend each Registration Statement if and as required by the rules,
regulations or instructions applicable to the registration form used by the
Company for such Registration Statement or by the Securities Act or by any other
rules and regulations thereunder for registrations, and the Company agrees to
notify the Holders of Registrable Securities or Registrable Liquidated Damages
Warrant Securities of any such supplement or amendment promptly after its being
used or filed with the Commission.

                        2(b) or Section 2(d), as applicable; provided, however,
                        that, no fewer than five (5) calendar days before filing

                        facts, during the Effectiveness Period, which makes any
                        statement made in such Registration Statement or the
                        related Prospectus untrue in any material respect or
                        which causes such Registration Statement or Prospectus

                        make the statements therein, in the light of the
                        circumstances under which they were made, not misleading

                        suspension of the qualification (or exemption from
                        qualification) of any of the Registrable Securities or
                        Registrable Liquidated Damages Warrant Securities for
                        sale in any jurisdiction at the earliest possible

                        each preliminary Prospectus) as such Holder from time to
                        time may reasonably request (it being understood that
                        the Company consents to the use of the Prospectus by
                        each of the selling Holders in connection with the

                        Liquidated Damages Warrant Securities by such Holder;

                         document, and provide revised or supplemented
                         Prospectuses to the Holders so that, as thereafter
                         delivered to the purchasers of the Registrable
                         Securities or Registrable Liquidated Damages Warrant
                         Securities, such Prospectus will not include any untrue
                         statement of a material fact or omit to state a
                         material fact necessary in order to make the statements
                         therein, in the light of the circumstances under which
                         they were made, not misleading;

                         which is to be incorporated by reference into a
                         Registration Statement or a Prospectus after the
                         initial filing of such Registration Statement, provide
                         a reasonable number of copies of such document to the

                         the NASD;

                  (xi)   take all other steps reasonably necessary to effect the

                         Registrable Liquidated Damages Warrant Securities
                         covered by a Registration Statement contemplated
                         hereby;

                  (xii)  use its best efforts to cause all Registrable
                         Securities or Registrable Liquidated Damages Warrant
                         Securities registered pursuant to this Agreement to be
                         listed on each securities exchange, interdealer

                         securities issued by the Company are then listed;

                  (xiii) cooperate with the Holders to facilitate the timely
                         preparation and delivery of certificates representing
                         Registrable Securities or Registrable Liquidated
                         Damages Warrant Securities to be delivered to a
                         transferee pursuant to the Registration Statement,
                         which certificates shall be free, to the extent
                         permitted by the Purchase Agreement, of all restrictive
                         legends, and to enable such Registrable Securities or
                         Registrable Liquidated Damages Warrant Securities to be
                         in such denominations and registered in such names as
                         any such Holders may request;

                        any amendment or supplement thereto without the consent
                        of the holders of a majority in interest of the
                        Registrable Securities or Registrable Liquidated Damages
                        Warrant Securities, as the case may be; and

                  (xv)  notwithstanding any other provision of this Section
                        3(a), if the Company becomes ineligible to use the
                        registration form on which the Registration Statement is
                        filed and declared effective pursuant to Section 2(a) or
                        Section 2(c), thereby precluding any Holder from using
                        the related Prospectus, the Company shall use its best
                        efforts to prepare and file either a post effective
                        amendment to the Registration Statement to convert such
                        registration statement to, or a new Registration
                        Statement on, another registration form which the
                        Company is eligible to use within thirty (30) days after
                        the date that the Company becomes ineligible, provided
                        such other registration form shall be available for the
                        sale of the Registrable Securities or Registrable
                        Liquidated Damages Warrant Securities by the selling
                        Holders thereof and such amended or new Registration
                        Statement shall remain subject in all respects to the
                        provisions of this Section 3(a).

            (b) Holders' Obligations.

                  (i)   Each Holder agrees that, upon receipt of any notice from
                        the Company of the occurrence of any event specified in
                        Sections 3(a)(iv)(B), 3(a)(iv)(C), 3(a)(iv)(E),
                        3(a)(iv)(F) or any Delay Notice, such Holder will
                        forthwith discontinue disposition of Registrable
                        Securities or Registrable Liquidated Damages Warrant
                        Securities pursuant to the Registration Statement at
                        issue until such Holder's receipt of the copies of the
                        supplemented or amended Prospectus contemplated by
                        Section 3(a)(viii) or until it is advised in writing
                        (the "ADVICE") by the Company that the use of the
                        applicable Prospectus may be resumed, and, if so
                        directed by the Company, such Holder will deliver to the
                        Company (at the Company's expense) all copies in such
                        Holder's possession, other than permanent file copies
                        then in such Holder's possession, of the Prospectus
                        covering such Registrable Securities or Registrable
                        Liquidated Damages Warrant Securities current at the
                        time of receipt of such notice.

                  (ii)  Each Holder agrees that the Company may require each
                        seller of Registrable Securities or Registrable
                        Liquidated Damages Warrant Securities as to which any
                        registration is being effected to furnish to it such
                        information regarding such seller as may be required by
                        the staff of the Commission to be included in the
                        applicable Registration Statement, the Company may
                        exclude from such registration the Registrable
                        Securities or Registrable Liquidated Damages Warrant
                        Securities of any seller who fails to furnish such
                        information which is not otherwise readily available to
                        the Company within ten (10) Business Days after
                        receiving such request, and the Company shall have no
                        obligation to register under the Securities Act the
                        Registrable Securities or Registrable Liquidated

                        Damages Warrant Securities of a seller who so fails to
                        furnish such information; provided that upon being
                        furnished with such information by a Holder, including
                        by any permitted transferee of Registrable Securities or
                        Registrable Liquidated Damages Warrant Securities,
                        whether before or after the Registration Statement is
                        declared effective, the Company shall as promptly as
                        reasonably practicable file a post-effective amendment
                        to the Registration Statement, or a supplement to the
                        Prospectus, for purposes of including such Holder as a
                        selling Holder under the Registration Statement.

4.    REGISTRATION EXPENSES.

      All Registration Expenses will be borne by the Company whether or not the
Registration Statement becomes effective. "REGISTRATION EXPENSES" means all fees
and expenses incident to the performance of, or compliance with, this Agreement
by the Company, including, without limitation, (i) all registration and filing
fees (including, without limitation, fees and expenses of compliance with
securities or "blue sky" laws (including, without limitation, fees and

qualifications of the Registrable Securities or Registrable Liquidated Damages
Warrant Securities and determination of the eligibility of the Registrable
Securities or Registrable Liquidated Damages Warrant Securities for investment
under the laws of such jurisdictions as the Holders of a majority of the
Registrable Securities or Registrable Liquidated Damages Warrant Securities
being sold may designate)), (ii) printing expenses (including, without
limitation, expenses of printing certificates for Registrable Securities or
Registrable Liquidated Damages Warrant Securities in a form eligible for deposit

shall it include underwriting fees, discounts or commissions relating to the
offer and sale of Registrable Securities or Registrable Liquidated Damages
Warrant Securities, which shall be borne by the Holders included in such

5.    INDEMNIFICATION.

            (a) Indemnification by the Company.

                  The Company will indemnify and hold harmless, to the fullest
extent permitted by law, each Holder whose Registrable Securities or Registrable
Liquidated Damages Warrant Securities are registered pursuant to this Agreement,
the officers, directors, agents, members, partners, limited partners and
employees of each of them, each Person who controls such Holder (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act)
and the officers, directors, agents, members, partners, limited partners and
employees of any such controlling Person, from and against any and all losses,
claims, damages, liabilities, costs (including, without limitation, the costs of
investigation and attorneys' fees) and expenses (collectively, "LOSSES"), as
incurred, arising out of or based upon any untrue or alleged untrue statement of
a material fact contained in any Registration Statement, preliminary Prospectus
or Prospectus or in any amendment or supplement thereto, or arising out of or
based upon any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as the same are based upon information furnished in
writing to the Company by such Holder expressly for use therein; provided,
however, that the Company will not be liable to any Holder to the extent that
any such Losses arise out of or are based upon an untrue statement or alleged
untrue statement or omission or alleged omission made in any preliminary
Prospectus if either (A) (i) after receiving copies thereof from the Company,
such Holder failed to send or deliver a copy of the Prospectus with or prior to
the delivery of written confirmation of the sale by such Holder to the Person
asserting the claim from which such Losses arise and (ii) the Prospectus would
have corrected in all material respects such untrue statement or alleged untrue
statement or such omission or alleged omission; or (B) such untrue statement or
alleged untrue statement, omission or alleged omission is corrected in all
material respects in an amendment or supplement to the Prospectus previously
furnished by or on behalf of the Company with copies of the Prospectus as so
amended or supplemented, and, after receiving copies thereof from the Company,
such Holder thereafter fails to deliver such Prospectus as so amended or
supplemented prior to or concurrently with the sale of a Registrable Security or
Registrable Liquidated Damages Warrant Security to the Person asserting the
claim from which such Losses arise. Such indemnity shall remain in full force
and effect regardless of any investigation made by or on behalf of any Holder or
any officer, director, agent or employee of such Holder.

            (b) Indemnification by Holders of Registrable Securities or
      Registrable Liquidated Damages Warrant Securities.

                  In connection with any Registration Statement in which a
Holder is participating, such Holder will furnish to the Company in writing such
information concerning the Holder as the Company reasonably requests concerning
such Holder for use in connection with any Registration Statement or Prospectus
and will severally and not jointly indemnify, to the fullest extent permitted by
law, the Company, its directors and officers, agents and employees, each Person
who controls the Company (within the meaning of Section 15 of the Securities Act
and Section 20 of the Exchange Act), and the directors, officers, agents or
employees of such controlling Persons, from and against any and all Losses
arising out of or based upon (i) any disposition of Registrable Securities or
Registrable Liquidated Damages Warrant Securities after

                                       16
<PAGE>

receiving notice of a Delay Period and prior to receiving Advice under Section
3(b)(i) that use of the Prospectus may be resumed or (ii) any untrue statement
of a material fact contained in any Registration Statement, Prospectus or
preliminary Prospectus or arising out of or based upon any omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading, to the extent, but only to the extent, that such untrue
statement or omission is finally judicially determined by a court of competent
jurisdiction to have been contained in any information so furnished in writing
by such Holder to the Company expressly for use in such Registration Statement
or Prospectus and to have been relied upon by the Company in the preparation of
such Registration Statement, Prospectus or preliminary Prospectus. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of the Company or any officer, director, agent or employee
of the Company. In no event will the liability of any selling Holder under this
Section 5(b) be greater in amount than the excess of the amount by which the
total price at which the Registrable Securities or Registrable Liquidated
Damages Warrant Securities sold by such Indemnifying Party and distributed to
the public pursuant to the applicable Registration Statement (net of all related
expenses) is over the amount of any damages which such Indemnifying Party has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.

            (c) Conduct of Indemnification Proceedings.

                  If any Person shall become entitled to indemnity hereunder (an
"INDEMNIFIED PARTY"), such Indemnified Party shall give prompt notice to the
party from which such indemnity is sought (the "INDEMNIFYING PARTY") of any
claim or of the commencement of any action or proceeding with respect to which
such Indemnified Party seeks indemnification or contribution pursuant hereto;
and the Indemnifying Party shall have the right to assume the defense thereof,
including the employment of counsel reasonably satisfactory to the Indemnified
Party and the payment of all fees and expenses incurred in connection with
defense thereof; provided, however, that the failure to so notify the
Indemnifying Party will not relieve the Indemnifying Party from any obligation
or liability except to the extent that it shall be finally determined by a court
of competent jurisdiction that the Indemnifying Party has been prejudiced
materially by such failure.

                  An Indemnified Party shall have the right to employ separate
counsel in any such proceeding and to participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in
writing to pay such fees and expenses; (2) the Indemnifying Party shall have
failed promptly to assume the defense of such proceeding and to employ counsel
reasonably satisfactory to the Indemnified Party in any such proceeding; or (3)
the named parties to any such proceeding (including any impleaded parties)
include both such Indemnified Party and the Indemnifying Party, and such
Indemnified Party shall have been advised by counsel that a conflict of interest
is likely to exist if the same counsel were to represent such Indemnified Party
and the Indemnifying Party (in which case, if such Indemnified Party notifies
the Indemnifying Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and the reasonable fees and expenses of one
separate counsel (and one local counsel in each applicable jurisdiction) shall
be at the expense of the Indemnifying Party).

                                       17
<PAGE>

                  All Losses (including any fees and expenses incurred in
connection with investigating or preparing to defend such action or proceeding)
will be paid to the Indemnified Party, as incurred, within ten (10) Business
Days of written notice thereof to the Indemnifying Party upon receipt of an
undertaking to repay such amount if it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder. The Indemnifying
Party will not consent to entry of any judgment or enter into any settlement or
otherwise seek to terminate any action or proceeding in which any Indemnified
Party is or could be a party and as to which indemnification or contribution
could be sought by such Indemnified Party under this Section 5, unless such
judgment, settlement or other termination includes, as an unconditional term
thereof, the giving by the claimant or plaintiff to such Indemnified Party of a
release, in form and substance reasonably satisfactory to the Indemnified Party,
from all liability in respect of such claim or litigation for which such
Indemnified Party would be entitled to indemnification hereunder and shall not
include a statement as to the admission of fault or culpability of the
Indemnified Party.

            (d) Contribution.

                  If the indemnification provided for in this Section 5 is
unavailable to an Indemnified Party under Section 5(a) or 5(b) hereof in respect
of any Losses or is insufficient to hold such Indemnified Party harmless, then
each applicable Indemnifying Party, in lieu of or in addition to indemnifying
such Indemnified Party, as applicable, will, jointly and severally, contribute
to the amount paid or payable by such Indemnified Party as a result of such
Losses, in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party or Indemnifying Parties, on the one hand, and such
Indemnified Party, on the other hand, in connection with the actions, statements
or omissions that resulted in such Losses as well as any other relevant
equitable considerations. The relative fault of such Indemnifying Party or
Indemnifying Parties, on the one hand, and such Indemnified Party, on the other
hand, will be determined by reference to, among other things, whether any action
in question, including any untrue or alleged untrue statement of a material fact
or omission or alleged omission of a material fact, has been taken or made by,
or related to information supplied by, such Indemnifying Party or Indemnified
Party, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such action, statement or omission. The amount
paid or payable by a party as a result of any Losses will be deemed to include,
subject to any limitations set forth in Section 5(c), any reasonable legal or
other fees or expenses incurred by such party in connection with any action or
proceeding to the extent such party would have been indemnified for such fees
and expenses if the indemnification provided for in this Section 5(d) was
available to such party in accordance with its terms.

                  The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 5(d) were determined by pro
rata allocation or by any other method of allocation that does not take into
account the equitable considerations referred to in the immediately preceding
paragraph. Notwithstanding the provisions of this Section 5(d), an Indemnifying
Party that is a selling Holder will not be required to contribute any amount in
excess of the amount by which the total price at which the Registrable
Securities or Registrable Liquidated Damages Warrant Securities sold by such
Indemnifying Party and distributed to the public pursuant to the applicable
Registration Statement (net of all related expenses) exceeds the amount of any
damages which such Indemnifying Party has otherwise been required to pay by

                                       18
<PAGE>

reason of such untrue or alleged untrue statement or omission or alleged
omission. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) will be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

                  The indemnity, contribution and expense reimbursement
obligations of a party hereunder will be in addition to any liability such party
may otherwise have hereunder or otherwise.

6.    MISCELLANEOUS.

            (a) Reporting.

                  With a view to making available to the Holders the benefits of
Rule 144 or any other similar rule or regulation of the Commission that may at
the time permit the Holders to sell securities of the Company to the public
without registration, for so long as the Holders continue to own Registrable
Securities or Registrable Liquidated Damages Warrant Securities, the Company
shall use commercially reasonable efforts to:

                  (i)   Make and keep public information available, as those
                        terms are understood and defined in Rule 144, and file
                        with the Commission in a timely manner all reports and
                        other documents required of the Company under the
                        Securities Act and the Exchange Act; and

                  (ii)  Furnish to each Holder, for so long as the Holder owns
                        Registrable Securities or Registrable Liquidated Damages
                        Warrant Securities, promptly upon request, a written
                        statement by the Company, if true, that it has complied
                        with the applicable reporting requirements of Rule 144,
                        the Securities Act and the Exchange Act, a copy of the
                        most recent annual or quarterly report of the Company,
                        and such other information as may be reasonably
                        requested to permit the Holders to sell such securities
                        pursuant to Rule 144 without registration.

            (b) Remedies.

                  In the event of a breach by the Company of its obligations
under this Agreement, each Holder, in addition to being entitled to exercise all
rights granted by law, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of any of the provisions of this Agreement and hereby
further agrees that, in the event of any action for specific performance in
respect of such breach, it will waive the defense that a remedy at law would be
adequate.

            (c) Amendments and Waivers.

                  (i)   The provisions of this Agreement may not be amended,
                        modified or supplemented, and waivers or consents to
                        departures from the provisions hereof may not be given
                        unless the Company has obtained the written

                                       19
<PAGE>

                        consent of Holders of at least 75% of the
                        then-outstanding Registrable Securities and Registrable
                        Liquidated Damages Warrant Securities.

                  (ii)  Any amendment or waiver effected in accordance with this
                        Section 6(c) shall be binding upon each holder of
                        Registrable Securities or Registrable Liquidated Damages
                        Warrant Securities at the time outstanding, each future
                        Holder of all such securities, and the Company.

                  (iii) No failure or delay by any party in exercising any
                        right, power or privilege hereunder will operate as a
                        waiver thereof, nor will any single or partial exercise
                        thereof preclude any other or further exercise thereof
                        or the exercise of any other right, power or privilege.
                        The rights and remedies herein provided will be
                        cumulative and not exclusive of any rights or remedies
                        provided by law.

may assign its rights and obligations under this Agreement to a third party in
connection with any transfer of Registrable Securities or Registrable Liquidated
Damages Warrant Securities (a "PERMITTED TRANSFEREE"). Notwithstanding the

                  This Agreement shall be governed by and construed in

EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY OR DISPUTE THAT MAY

RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I)
NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH SUCH PARTY
UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH SUCH
PARTY MAKES THIS WAIVER VOLUNTARILY, AND (IV) EACH SUCH PARTY HAS BEEN INDUCED
TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION 6(k).

            (l) Severability.

                  The holding of any provision of this Agreement to be invalid
or unenforceable by a court of competent jurisdiction shall not affect any other
provision of this Agreement, which shall remain in full force and effect. If any
provision of this Agreement shall be declared by a court of competent
jurisdiction to be invalid, illegal or incapable of being enforced in whole or
in part, such provision shall be interpreted so as to remain enforceable to the
maximum extent permissible consistent with applicable law and the remaining
conditions and provisions or

                                       22
<PAGE>

portions thereof shall nevertheless remain in full force and effect and
enforceable to the extent they are valid, legal and enforceable, and no
provisions shall be deemed dependent upon any other covenant or provision unless
so expressed herein.

            (m) Entire Agreement.

                  This Agreement constitutes the entire understanding and
agreement among the parties relating to the subject matter hereof and supersedes
any and all prior agreements, representations or understandings, both written
and oral, with respect to the subject matter hereof. Nothing in this Agreement,
express or implied, is intended to confer upon any Person, other than the
parties hereto and their respective successors and assigns, any rights,
remedies, obligations, or liabilities under or by reason of this Agreement,
except as expressly provided herein.

            (n) No Strict Construction.

                  The parties hereto have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement will be construed as
if drafted jointly by the parties hereto, and no presumption or burden of proof
will arise favoring or disfavoring any party by virtue of the authorship of any
of the provisions of this Agreement.

            (o) Third Party Beneficiaries.

                  This Agreement and all of its provisions and conditions are
for the benefit of the parties to this Agreement, any Permitted Transferee and
solely with respect to the provisions of Section 5 hereof, any Indemnified
Party.

            (p) Termination.

                  This Agreement shall terminate on the date on which there
cease to be any Registrable Securities and Registrable Liquidated Damages
Warrant Securities outstanding. The provisions of Section 5 and Section 6(o)
shall survive the termination of this Agreement.

            (q) Independent Nature of Holders' Obligations and Rights.

                  The obligations of each Holder hereunder are several and not
joint with the obligations of any other Holder hereunder, and no Holder shall be
responsible in any way for the performance of the obligations of any other
Holder hereunder. Nothing contained herein or in any other agreement or document
delivered at any closing, and no action taken by any Holder pursuant hereto or
thereto, shall be deemed to constitute the Holders as a partnership, an
association, a joint venture or any other kind of entity, or create a
presumption that the Holders are in any way acting in concert with respect to
such obligations or the transactions contemplated by this Agreement. Each Holder
shall be entitled to protect and enforce its rights, including, without
limitation, the rights arising out of this Agreement, and it shall not be
necessary for any other Holder to be joined as an additional party in any
proceeding for such purpose.

            (r) No Conflicting Agreements.

                  The Company represents, warrants and agrees that (i) it has
not entered into, and shall not, on or after the date of this Agreement, enter
into, any agreement that is inconsistent with the rights granted to the Holders
in this Agreement or otherwise conflicts with the provisions hereof, (ii) it has
not previously entered into any agreement which remains in effect granting any
registration rights with respect to any of the Company's securities to any
person and (iii) without limiting the generality of the foregoing, without the
written consent of the Holders of a majority of the Registrable Securities and
Registrable Liquidated Damages Warrant Securities, it shall not grant to any
person the right to request the Company to register any Company securities under
the Securities Act unless the rights so granted are not in conflict or
inconsistent with the provisions of this Agreement.

            (s) No Inferences.

                  Nothing in this Agreement shall create any inference that any
Purchaser is required to register any securities of the Company for resale under
the Securities Act, other than the Common Stock issuable pursuant to the
Purchase Agreement and the Warrant Common Stock.

                              PLAN OF DISTRIBUTION

      The selling Holders, or their pledgees, donees, transferees, or any of
their successors in interest selling shares received from a named selling Holder
as a gift, partnership distribution or other non-sale-related transfer after the
date of this prospectus (all of whom may be selling Holders), may offer and sell
the securities from time to time on any stock exchange or automated inter-dealer
quotation system on which the securities are listed, in the over-the-counter
market, in privately negotiated transactions or otherwise, at fixed prices that
may be changed, at market prices prevailing at the time of sale, at prices
related to prevailing market prices or at prices otherwise negotiated. The
selling Holders may sell the securities by one or more of the following methods,
without limitation:

      (a) block trades in which the broker or dealer so engaged will attempt to
sell the securities as agent but may position and resell a portion of the block
as principal to facilitate the transaction;

      (b) purchases by a broker or dealer as principal and resale by the broker
or dealer for its own account pursuant to this prospectus;

      (c) on any national securities exchange or quotation service on which the
securities are listed or quoted at the time of sale;

      (d) in the over-the-counter market;

      (e) otherwise than on such exchanges or services or in the
over-the-counter market;

      (f) ordinary brokerage transactions and transactions in which the broker
solicits purchases;

      (g) privately negotiated transactions;

      (h) short sales;

      (i) through the writing of options on the securities, whether or not the
options are listed on an options exchange;

      (j) through the distribution of the securities by any selling Holder to
its partners, members or stockholders;

      (k) one or more underwritten offerings on a firm commitment or best
efforts basis;

      (l) transactions which may involve crosses or block transactions;

                                       B-1
<PAGE>

      (m) to cover hedging transactions (other than "short sales" as defined in
Rule 3b-3 under the Exchange Act) made pursuant to this prospectus;

      (n) by pledge to secure debts or other obligations;

      (o) any combination of any of these methods of sale; and

      (p) any other method permitted pursuant to applicable law.

      The selling Holders may also transfer the securities by gift. We do not
know of any arrangements by the selling Holders for the sale of any of the
securities.

      The selling Holders may engage brokers and dealers, and any brokers or
dealers may arrange for other brokers or dealers to participate in effecting
sales of the securities. These brokers, dealers or underwriters may act as
principals, or as an agent of a selling Holder. Broker-dealers may agree with a
selling Holder to sell a specified number of the securities at a stipulated
price per security. If the broker-dealer is unable to sell securities acting as
agent for a selling Holder, it may purchase as principal any unsold securities
at the stipulated price. Broker-dealers who acquire securities as principals may
thereafter resell the securities from time to time in transactions in any stock
exchange or automated inter-dealer quotation system on which the securities are
then listed, at prices and on terms then prevailing at the time of sale, at
prices related to the then-current market price or in negotiated transactions.
Broker-dealers may use block transactions and sales to and through
broker-dealers, including transactions of the nature described above. The
selling Holders may also sell the securities in accordance with Rule 144 under
the Securities Act of 1933, as amended, rather than pursuant to this prospectus,
regardless of whether the securities are covered by this prospectus.

      From time to time, one or more of the selling Holders may pledge,
hypothecate or grant a security interest in some or all of the securities owned
by them. The pledgees, secured parties or persons to whom the securities have
been hypothecated will, upon foreclosure in the event of default, be deemed to
be selling Holders. As and when a selling Holder takes such actions, the number
of securities offered under this prospectus on behalf of such selling Holder
will decrease. The plan of distribution for that selling Holder's securities
will otherwise remain unchanged. In addition, a selling Holder may, from time to
time, sell the securities short, and, in those instances, this prospectus may be
delivered in connection with the short sales and the securities offered under
this prospectus may be used to cover short sales.

      To the extent required under the Securities Act of 1933, the aggregate
amount of selling Holders' securities being offered and the terms of the
offering, the names of any agents, brokers, dealers or underwriters and any
applicable commission with respect to a particular offer will be set forth in an
accompanying prospectus supplement. Any underwriters, dealers, brokers or agents
participating in the distribution of the securities may receive compensation in
the form of underwriting discounts, concessions, commissions or fees from a
selling Holder and/or purchasers of selling Holders' securities of securities,
for whom they may act (which compensation as to a particular broker-dealer might
be in excess of customary commissions).

      The selling Holders and any underwriters, brokers, dealers or agents that
participate in the distribution of the securities may be deemed to be
"underwriters" within the meaning of the

                                      B-2
<PAGE>

Securities Act of 1933, and any discounts, concessions, commissions or fees
received by them and any profit on the resale of the securities sold by them may
be deemed to be underwriting discounts and commissions.

      A selling Holder may enter into hedging transactions with broker-dealers
and the broker-dealers may engage in short sales of the securities in the course
of hedging the positions they assume with that selling Holder, including,
without limitation, in connection with distributions of the securities by those
broker-dealers. A selling Holder may enter into option or other transactions
with broker-dealers that involve the delivery of the securities offered hereby
to the broker-dealers, who may then resell or otherwise transfer those
securities. A selling Holder may also loan or pledge the securities offered
hereby to a broker-dealer and the broker-dealer may sell the securities offered
hereby so loaned or upon a default may sell or otherwise transfer the pledged
securities offered hereby.

      The selling Holders and other persons participating in the sale or
distribution of the securities will be subject to applicable provisions of the
Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder, including Regulation M. This regulation may limit the timing of
purchases and sales of any of the securities by the selling Holders and any
other person. The anti-manipulation rules under the Securities Exchange Act of
1934 may apply to sales of securities in the market and to the activities of the
selling Holders and their affiliates. Furthermore, Regulation M may restrict the
ability of any person engaged in the distribution of the securities to engage in
market-making activities with respect to the particular securities being
distributed for a period of up to five business days before the distribution.
These restrictions may affect the marketability of the securities and the
ability of any person or entity to engage in market-making activities with
respect to the securities.

      We have agreed to indemnify in certain circumstances the selling Holders
and any brokers, dealers and agents who may be deemed to be underwriters, if
any, of the securities covered by the registration statement, against certain
liabilities, including liabilities under the Securities Act of 1933. The selling
Holders have agreed to indemnify us in certain circumstances against certain
liabilities, including liabilities under the Securities Act of 1933, as amended.

      The securities offered hereby were originally issued to the selling
Holders pursuant to an exemption from the registration requirements of the
Securities Act of 1933, as amended. We agreed to register the securities under
the Securities Act of 1933, and to keep the registration statement of which this
prospectus is a part effective until the date on which the selling Holders have
sold all of the securities. We have agreed to pay all expenses in connection
with this offering, including the fees and expenses of counsel or other advisors
to the selling Holders, but not including underwriting discounts, concessions or
commissions of the selling Holders.

      We will not receive any proceeds from sales of any securities by the
selling Holders.

      We cannot assure you that the selling Holders will sell all or any portion
of the securities offered hereby.

                       FORM OF OPINIONS OF COMPANY COUNSEL

A.    The Company is validly existing as a corporation and in good standing
      under the laws of the State of Delaware and the Company has the corporate
      power and authority to conduct its business as it is, to our knowledge,
      currently conducted, to enter into and perform its obligations under the
      Transaction Documents, and to carry out the transactions contemplated by
      the Transaction Documents. Based solely on a review of a good standing
      certificate from the Secretary of State of the State of California, such
      counsel confirms that the Company is in good standing in the State of
      California.

B.    The Unsubscribed Shares, the Standby Commitment Fee Warrants and the
      Warrant Shares have been duly authorized or reserved for issuance by all
      necessary corporate action on the part of the Company; and the
      Unsubscribed Shares and the Standby Commitment Fee Warrants, when issued,
      sold and, in the case of the Unsubscribed Shares, delivered against
      payment therefor, in accordance with the provisions of the Purchase
      Agreement, and the Warrant Shares, when issued upon the exercise of the
      Standby Commitment Fee Warrants and the receipt of the exercise price
      provided for under the Standby Commitment Fee Warrants, will be validly
      issued, fully paid and non-assessable.

C.    The execution and delivery by the Company of the Transaction Documents,
      and the consummation by the Company of the transactions contemplated
      thereby, have been duly authorized by all necessary corporate action on
      the part of the Company, and the Transaction Documents have been duly
      executed and delivered by the Company. Each of the Transaction Documents
      (other than the Standby Commitment Fee Warrants) constitutes the valid and
      binding obligation of the Company, enforceable against the Company in
      accordance with its terms.1

D.    The execution and delivery by the Company of the Transaction Documents,
      and the consummation by the Company of the transactions contemplated
      thereby, do not (a) violate the provisions of the Delaware General
      Corporation Law or any U.S. federal or New York state law, rule or
      regulation applicable to the Company; (b) violate the provisions of the
      Company's Certificate of Incorporation or By-laws, each as amended to
      date; (c) violate any judgment, decree, order or award of any court,
      governmental body or arbitrator specifically naming the Company of which
      we are aware; or (d) constitute a breach by the Company of, or constitute
      a default by the Company under any agreement to which the Company is a
      party and is listed as a material contract (Item 10) in the exhibits to
      the Company's Form 10-K for the fiscal year ended December 31, 2004.

E.    Based in part on the representations of each of the Purchasers in Sections
      3.4, 3.5, 3.8 and 3.9 of the Purchase Agreement, the offer and sale of the
      Unsubscribed Shares and the Standby Commitment Fee Warrants pursuant to
      the Purchase Agreement, and the offer and sale of the Warrant Shares
      pursuant to the terms of the Standby Commitment Fee Warrants may be made
      without registration under the Securities Act of 1933, as amended.

      event the Company shall issue to the Holder the number of Warrant Shares
      determined as follows:

                X = Y (A-B)/A

         where:

                X = the number of Warrant Shares to be issued to the Holder.

                Y = the number of Warrant Shares with respect to which this
                Warrant is being exercised (which shall include both the
                number of Warrant Shares issued to the Holder and the number

Business Days, after the rights represented by this Warrant shall have been so
exercised; and, unless this Warrant has expired, a new Warrant representing the

exercised shall also be issued to the Holder hereof within such time. The person
in whose name any certificate for shares of Common Stock is issued upon exercise
of this Warrant shall for all purposes be deemed to have become the holder of
record of such shares on the date on which the Holder shall have complied with
the conditions for exercise of this Warrant set forth above, irrespective of the
date of delivery of such certificate, except that, if the date of such
compliance is a date when the stock transfer books of the Company are closed,
such person shall be deemed to have become the holder of such shares at the
close of business on the next succeeding date on which the stock transfer books
are open. Notwithstanding anything in the foregoing to the contrary, for
purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that Warrant Shares issued in a cashless exercise
transaction pursuant to Section 2.1(b) above shall be deemed to have been
acquired by the Holder, and the holding period for the Warrant Shares shall be
deemed to have commenced, on the issue date of this Warrant.

            2.3 Transfer Restriction Legend. Each certificate for Warrant Shares
shall bear the following legend (and any additional legend required by (i) any
applicable state securities laws and (ii) any securities exchange upon which
such Warrant Shares may, at the time of such exercise, be listed) on the face
thereof unless at the time of exercise such Warrant Shares shall be registered
under the Securities Act:

                                       3
<PAGE>

            "The shares represented by this certificate have not been registered
            under the Securities Act of 1933, as amended (the "SECURITIES ACT")
            AND/OR QUALIFIED UNDER ANY STATE SECURITIES LAWS. SUCH SHARES MAY
            NOT be OFFERED OR sold or transferred EXCEPT (A) PURSUANT TO AN
            EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND
            REGISTRATION AND/OR QUALIFICATION UNDER APPLICABLE STATE SECURITIES
            LAWS, (B) IN A TRANSACTION WHICH IS EXEMPT FROM REGISTRATION UNDER
            THE SECURITIES ACT AND REGISTRATION AND/OR QUALIFICATION UNDER
            APPLICABLE STATE SECURITIES LAWS PROVIDED THAT AT THE ISSUER'S
            REQUEST, THE TRANSFEROR THEREOF SHALL HAVE DELIVERED TO THE ISSUER
            AN OPINION OF COUNSEL (WHICH OPINION SHALL BE IN FORM, SUBSTANCE AND
            SCOPE REASONABLY SATISFACTORY TO THE ISSUER FROM COUNSEL REASONABLY
            SATISFACTORY TO THE ISSUER) TO THE EFFECT THAT SUCH SECURITIES MAY
            BE SOLD OR TRANSFERRED PURSUANT TO AN EXEMPTION FROM SUCH
            REGISTRATION, OR (C) SUCH SECURITIES MAY BE SOLD PURSUANT TO RULE
            144 PROMULGATED UNDER THE SECURITIES ACT."

            Any certificate issued at any time in exchange or substitution for
any certificate bearing such legend shall also bear such legend unless, in the
opinion of counsel for the Holder thereof (which counsel shall be satisfactory
to the Company) the securities represented thereby are not, at such time,
required by law to bear such legend. The foregoing legend shall be removed from
the certificates representing any Warrant Shares, at the request of the Holder
thereof, at such time as they become eligible for resale pursuant to Rule 144(k)
under the Securities Act or as they have been sold pursuant to a registration
statement declared effective by the Securities and Exchange Commission or
pursuant to Rule 144 under the Securities Act. At the request of the Company,
the Company shall have the right to receive an opinion of counsel for the
Holder, reasonably satisfactory to the Company, to the effect that the transfer
of the Warrant Shares is exempt from the registration requirements of the
Securities Act, prior to the removal of the legend if the request for removal is
being made pursuant to Rule 144 or Rule 144(k) under the Securities Act.

      SECTION 3. COVENANTS AS TO COMMON STOCK. The Company shall at all times
reserve and keep available out of its authorized but unissued Common Stock (or
out of shares of Common Stock held in its treasury) solely for the purpose of
issuance upon the exercise of this Warrant, the maximum number of Warrant Shares
issuable upon the exercise of this Warrant. The Company covenants and agrees
that all shares of Common Stock that may be issued upon the exercise of the
rights represented by this Warrant shall, upon issuance, be validly issued,
fully paid and nonassessable, and free from all taxes, liens, preemptive rights
and charges with respect to the issue thereof. The Company shall take all such
actions as may be necessary to

                                       4
<PAGE>

ensure that all such Warrant Shares may be so issued without violation by the
Company of any applicable law or governmental regulation or any requirements of
any domestic securities exchange or quotation system upon which shares of Common
Stock or other securities constituting Warrant Shares may be listed or quoted
(except for official notice of issuance which shall be immediately delivered by
the Company upon each such issuance). The Company further covenants and agrees
that it shall pay when due and payable any and all federal and state documentary
or stamp taxes (other than federal or state income taxes) which may be payable
in respect of the issue of this Warrant or any Common Stock or certificates
therefor issuable upon the exercise of this Warrant, except that, if Warrant
Shares or new Warrants shall be registered in a name or names other than the
name of the Holder, funds sufficient to pay all transfer taxes payable as a
result of such transfer shall be paid by the Holder at the time of delivery of
the Notice of Exercise.

      SECTION 4. ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment of the
Warrant Price as provided in Section 5(a), Section 5(b), Section 5(c) or Section
5(f), the number of Warrant Shares shall be changed to the number determined by
multiplying the Warrant Price in effect immediately prior to such adjustment by
the number of Warrant Shares purchasable immediately prior to such adjustment
and dividing the product thereof by the Warrant Price resulting from such
adjustment.

      SECTION 5. ADJUSTMENT. The Warrant Price and the terms of the Warrant
shall be subject to adjustment from time to time as follows:

                  (a) If, at any time during the Term of this Warrant, the
      Company shall make or issue, a dividend or other distribution payable in
      additional shares of Common Stock, then and in each such event the Warrant
      Price then in effect immediately before such event shall be decreased as
      of the time of such issuance by multiplying the Warrant Price then in
      effect by a fraction:

                            (1) the numerator of which shall be the total number
of shares of Common Stock issued and outstanding immediately prior to the time
of such issuance, and

                            (2) the denominator of which shall be the total
number of shares of Common Stock issued and outstanding immediately prior to the
time of such issuance plus the number of shares of Common Stock issuable in
payment of such dividend or distribution.

                  (b) If, at any time during the Term of this Warrant, the
      number of shares of Common Stock outstanding is increased by a subdivision
      or split-up of shares of Common Stock, then, immediately after the date
      fixed for the determination of holders of Common Stock entitled to receive
      shares in such subdivision or split-up, the Warrant Price in effect
      immediately before the subdivision or split-up shall be appropriately
      decreased so that the number of shares of Common Stock issuable upon the
      exercise hereof shall be increased in proportion to such increase in
      outstanding shares.

                                       5
<PAGE>

            (c) If, at any time during the Term of this Warrant, the number of
   shares of Common Stock outstanding is decreased by a combination of the
   outstanding shares of Common Stock or reverse stock split, then, immediately
   after the effective date for such combination, the Warrant Price in effect
   immediately prior to such combination or reverse stock split shall be
   appropriately increased so that the number of shares of Common Stock issuable
   upon the exercise hereof shall be decreased in proportion to such decrease in
   outstanding shares.

            (d) If, at any time during the Term of this Warrant, the Company
   shall make or issue, or fix a record date for the determination of holders of
   Common Stock entitled to receive, a dividend or other distribution payable in
   securities of the Company (other than shares of Common Stock) or in cash or
   other property (other than dividends or distributions for which an adjustment
   is made pursuant to other provisions of this Section 5 or regular cash
   dividends paid out of earnings or earned surplus, determined in accordance
   with generally accepted accounting principles), then and in each such event
   provision shall be made so that the Holder shall receive upon the exercise
   hereof, in addition to the number of shares of Common Stock issuable
   hereunder, the kind and amount of securities of the Company, cash or other
   property which the Holder would have been entitled to receive had this
   Warrant been exercised on the effective date fixed for the determination of
   holders of Common Stock entitled to receive a dividend or distribution in
   such event and had the Holder thereafter, during the period from such date to
   and including the exercise date, retained any such securities receivable
   during such period, giving application to all adjustments called for during
   such period under this Section 5 with respect to the rights of the Holder.

            (e) In the case of any proposed consolidation or merger of the
   Company with another entity, or the proposed sale of all or substantially all
   of its assets to another person or entity, or any proposed consolidation,
   reorganization, recapitalization, or reclassification of the capital stock of
   the Company or other transaction, then, as a condition of such consolidation,
   merger, sale, consolidation, reorganization, recapitalization,
   reclassification or other transaction, the Company shall give 30 days' prior
   written notice thereof to the Holder hereof and lawful and adequate provision
   shall be made whereby the Holder shall thereafter have the right to receive
   upon the basis and upon the terms and conditions specified herein, in lieu of
   the Warrant Shares immediately theretofore purchasable hereunder, such shares
   of stock, securities, cash or assets as may (by virtue of such consolidation,
   merger, sale, consolidation, reorganization, recapitalization,
   reclassification or other transaction) be issued or payable with respect to
   or in exchange for the number of Warrant Shares purchasable hereunder
   immediately before such consolidation, merger, sale, reorganization,
   recapitalization, reclassification or other transaction. In any such case
   appropriate provision shall be made with respect to the rights and interests
   of the Holder to the end that the provisions hereof shall thereafter be
   applicable as nearly as may be practicable, in relation to any shares of
   stock, securities, cash or assets thereafter deliverable upon the exercise of
   this Warrant. Notwithstanding the foregoing sentences, if (x) there shall
   occur any consolidation, merger, sale, consolidation, reorganization,
   recapitalization or other transaction in which the Common Stock is converted
   into or exchanged for anything other than solely equity securities, and (y)
   the common stock of the acquiring or surviving company (which shall be
   understood to mean the ultimate parent of such company, if such company is
   not publicly traded and its ultimate parent is publicly traded) is publicly
   traded, then, as part of such

                                       6
<PAGE>

   consolidation, merger, sale, consolidation, reorganization, recapitalization,
   reclassification or other transaction, (i) the Holder shall have the right
   thereafter to receive upon the exercise hereof such number of shares of
   common stock of the acquiring or surviving company as is determined by
   multiplying (A) the number of shares of Common Stock subject to this Warrant
   immediately prior to such consolidation, merger, sale, consolidation,
   reorganization, recapitalization, reclassification or other transaction by
   (B) a fraction, the numerator of which is the Fair Market Value (as defined
   below) per share of Common Stock as of the effective date of such
   consolidation, merger, sale, consolidation, reorganization, recapitalization,
   reclassification or other transaction, as determined pursuant to Section 7,
   and the denominator of which is the fair market value per share of common
   stock of the acquiring or surviving company as of the effective date of such
   transaction, as determined in good faith by the Board of Directors of the
   Company (using the principles set forth in Section 7 to the extent
   applicable), and (ii) the exercise price per share of common stock of the
   acquiring or surviving company shall be the Warrant Price divided by the
   fraction referred to in clause (B) above. The Company shall not effect any
   such consolidation, merger, sale, reorganization, recapitalization,
   reclassification or other transaction unless, prior to the consummation
   thereof, the successor entity (if other than the Company) resulting from such
   consolidation, merger, sale, reorganization, recapitalization,
   reclassification or other transaction (including a purchaser of all or
   substantially all the Company's assets) assumes by written instrument the
   obligation to deliver to each Holder of Warrants such shares of stock,
   securities, cash or assets as, in accordance with the foregoing provisions,
   such Holder may be entitled to acquire upon exercise of Warrants.

            (f) If at any time the Company shall issue or sell any Common Stock
   (other than Common Stock issued (a) pursuant to the Company's existing or
   future stock option plans or pursuant to any other existing or future Common
   Stock related director or employee compensation plan of the Company approved
   by the board of directors of the Company (the "BOARD OF DIRECTORS"), (b) as
   consideration for the acquisition of a business or of assets, (c) to the
   Company's joint venture partners in exchange for interests in the relevant
   joint venture, (d) upon conversion of any shares of any series of preferred
   stock or as the payment of a dividend with respect to any series of preferred
   stock outstanding on the date hereof or the issuance of which caused an
   adjustment under the other provisions of this Section 5 or (e) upon the
   exercise or conversion of any security the issuance of which caused an
   adjustment under the other provisions of this Section 5 for a consideration
   per share less than the Warrant Price then in effect, or shall issue any
   options, rights, warrants or other securities convertible into or exercisable
   or exchangeable for Common Stock (other than such securities paid as
   dividends on any class of preferred stock outstanding on the date hereof or
   the issuance of which caused an adjustment under the other provisions of this
   Section 5) having a conversion, exercise or exchange price, together with the
   issue price of such securities, per share of Common Stock less than the
   Warrant Price then in effect, the Warrant Price to be in effect after such
   issuance or sale shall be determined by multiplying the Warrant Price in
   effect immediately prior to such issuance or sale by a fraction, (i) the
   denominator of which shall be the sum of (w) the number of shares of Common
   Stock outstanding immediately prior to such issuance or sale plus (x) the
   number of additional shares of Common Stock to be issued or sold (or, in the
   case of any options, rights, warrants or other convertible, exercisable or
   exchangeable securities, issued on conversion, exercise or exchange), and
   (ii) the numerator of which shall be the sum of (y) the number of shares of

                                       7
<PAGE>

   Common Stock outstanding immediately prior to such issuance and sale plus (z)
   the number of shares of Common Stock which the aggregate consideration
   received by the Company for the total number of additional shares of Common
   Stock so issued or sold (or issuable on conversion, exercise or exchange)
   would purchase at the Warrant Price in effect on the date of such issuance or
   sale. In case any portion of the consideration to be received by the Company
   shall be in a form other than cash, the fair market value (determined in
   accordance with the principles set forth in Section 7 to the extent
   applicable) of such non-cash consideration shall be utilized in the foregoing
   computation. Such adjustment shall be made successively whenever any such
   issuance or sale is made, and shall become effective immediately after such
   issuance or sale. If all the Common Stock deliverable upon exercise,
   conversion or exchange of securities convertible into Common Stock have not
   been issued when such securities are no longer outstanding, then the Warrant
   Price shall promptly be readjusted to the Warrant Price which would then be
   in effect had the adjustment upon the issuance of such securities been made
   on the basis of the actual number of Common Stock issued upon conversion,
   exercise or exchange of such securities.

            (g) Whenever the Warrant Price shall be adjusted as provided in this
   Section 5, the Company shall promptly prepare a statement showing the facts
   requiring such adjustment and the Warrant Price and number of Warrant Shares
   that shall be in effect after such adjustment, setting forth in reasonable
   detail and certifying the calculation of such adjustment. The Company shall
   cause a copy of such statement to be sent by mail, first class postage
   prepaid, to each Holder at its, his or her address appearing on the Company's
   records. The Company shall, as promptly as reasonably practicable after the
   written request at any time of the Holder (but in any event not later than 10
   days thereafter), furnish or cause to be furnished to the Holder a
   certificate setting forth (i) the Warrant Price then in effect and (ii) the
   number of shares of Common Stock and the amount, if any, of other securities,
   cash or property which then would be received upon the exercise of this
   Warrant.

            (h) Adjustments made pursuant to this Section 5 shall be made on the
   date such dividend, subdivision, split-up, reverse stock split, combination,
   distribution, issuance, sale, consolidation, reorganization,
   recapitalization, reclassification or other transaction, as the case may be,
   is made, and shall become effective at the close of business on the day such
   event becomes effective.

      SECTION 6. OWNERSHIP.

            6.1 Ownership of Warrant. The Company may deem and treat the person
   in whose name this Warrant is registered as the holder and owner hereof
   (notwithstanding any notations of ownership or writing hereon made by anyone
   other than the Company) for all purposes and shall not be affected by any
   notice to the contrary until presentation of this Warrant for registration of
   transfer as provided in this Section 6.

            6.2 Transfer and Replacement.

            (a) No Holder shall Transfer this Warrant other than (i) a Transfer
   to one or more of its Affiliates or (ii) if the Company first shall have been
   furnished with an opinion of legal counsel, reasonably satisfactory to the
   Company, to the effect that such Transfer is

                                       8
<PAGE>

   exempt from the registration requirements of the Securities Act.
   Notwithstanding the foregoing, no registration or opinion of counsel shall be
   required for, and a Transfer shall be permitted in the event of, a Transfer
   by a Holder which is a partnership to a partner of such partnership or a
   retired partner of such partnership or to the estate of any such partner or
   retired partner, or a Transfer by a Holder which is a limited liability
   company to a member of such limited liability company or a retired member or
   to the estate of any such member or retired member, provided that the
   transferee in each case agrees in writing to be subject to the terms of this
   Section 6. Any attempt to Transfer this Warrant other than in accordance with
   this Section 6 shall be null and void and no right, title or interest in or
   to such Warrant shall be Transferred to the purported transferee, buyer,
   donee, assignee or encumbrance holder. The Company will not give, and will
   not permit the Company's transfer agent to give, any effect to such attempted
   Transfer in its stock records.

            (b) Subject to Section 6.2(a), this Warrant and all rights hereunder
   are transferable in whole or in part upon the books of the Company by the
   Holder hereof in person or by duly authorized attorney, together with a
   properly executed Assignment (in the form of Exhibit C or Exhibit D hereto,
   as the case may be) and a new Warrant or Warrants, of the same tenor as this
   Warrant but registered in the name of the transferee or transferees (and in
   the name of the Holder, if a partial transfer is effected) shall be promptly
   made and delivered by the Company upon surrender of this Warrant duly
   endorsed, at the office of the Company referred to in Section 9 hereof. Upon
   receipt by the Company of evidence reasonably satisfactory to it of the loss,
   theft or destruction, and, in such case, of indemnity or security reasonably
   satisfactory to it, and upon surrender of this Warrant if mutilated, the
   Company shall promptly make and deliver a new Warrant of like tenor, in lieu
   of this Warrant. This Warrant shall be promptly cancelled by the Company upon
   the surrender hereof in connection with any transfer or replacement. Except
   as otherwise provided above, in the case of the loss, theft or destruction of
   a Warrant, the Company shall pay all expenses, taxes and other charges
   payable in connection with any transfer or replacement of this Warrant, other
   than documentary or stamp taxes (if any) payable in connection with a
   transfer of this Warrant, which shall be payable by the Holder. The Holder
   shall not transfer this Warrant and the rights hereunder except in compliance
   with federal and state securities laws.

      SECTION 7. FRACTIONAL SHARES. Fractional shares shall not be issued upon
the exercise of this Warrant but in any case where the Holder would, except for
the provisions of this Section 7, be entitled under the terms hereof to receive
a fractional share upon the complete exercise of this Warrant, the Company
shall, upon the exercise of this Warrant for the largest number of whole shares
then called for, pay a sum in cash equal to the excess of the Fair Market Value
of such fractional share over the Warrant Price for such fractional share on the
exercise date.

            (a) The Fair Market Value per share of Common Stock shall be
   determined as follows:

                  (i) If the Common Stock is listed on a national securities
exchange, the Nasdaq National Market or another nationally recognized trading
system as of the exercise date, the Fair Market Value per share of Common Stock
shall be deemed to be the

                                       9
<PAGE>

average of the high and low reported sale prices per share of Common Stock
thereon on the trading day immediately preceding the effective date or the
exercise date, as applicable (provided that if no such price is reported on such
day, the Fair Market Value per share of Common Stock shall be determined
pursuant to clause (ii)).

                  (ii) If the Common Stock is not listed on a national
securities exchange, the Nasdaq National Market or another nationally recognized
trading system as of the effective date or the exercise date, as applicable, the
Fair Market Value per share of Common Stock shall be deemed to be the amount
most recently determined by the Board to represent the fair market value per
share of the Common Stock (including without limitation a determination for
purposes of granting Common Stock options or issuing Common Stock under any
plan, agreement or arrangement with employees of the Company); and, upon request
of the Holder, the Board (or a representative thereof) shall, as promptly as
reasonably practicable but in any event not later than 3 Business Days after
such request, notify the Holder of the Fair Market Value per share of Common
Stock and furnish the Holder with reasonable documentation of the Board's
determination of such Fair Market Value. Notwithstanding the foregoing, if the
Board has not made such a determination within the three-month period prior to
the exercise date, then (A) the Board shall make, and shall provide or cause to
be provided to the Holder notice of, a determination of the Fair Market Value
per share of the Common Stock within 15 days of a request by the Holder that it
do so, and (B) payment in cash with respect to any fractional share as required
by Section 7 hereof shall be delayed until such determination is made and notice
thereof is provided to the Holder (it being understood that this shall not
prevent the Holder, at its option, from exercising the Warrant prior to such
determination).

      SECTION 8. SPECIAL ARRANGEMENTS OF THE COMPANY. The Company covenants and
agrees that during the Term of this Warrant, unless otherwise approved by the
Holder:

            8.1 Certain Actions. The Company shall not amend its charter to
eliminate as an authorized class of capital stock that class denominated as
"Common Stock" on the date hereof. The Company shall not by any action avoid or
seek to avoid the observance or performance of any terms of this Warrant or
impair or diminish its value, but shall at all times in good faith assist in the
carrying out of all such terms of Warrant. Without limiting the generality of
the foregoing, the Company shall 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.

            8.2 Shall Bind Successors. This Warrant and the rights evidenced
hereby shall be binding upon the Company and its successors and assigns and
shall inure to the benefit of the Holder and its permitted assigns to the extent
permitted by Section 6.2.

            8.3 No Exercise Interference; Par Value. Other than in accordance
with Section 6.2, the Company shall not close its books against the transfer of
this Warrant or of any Warrant Shares issued or issuable upon the exercise of
this Warrant in any manner which interferes with the timely exercise of this
Warrant. The Company shall from time to time take all such action as may be
necessary to assure that the par value per share of the unissued Warrant Shares
acquirable upon exercise of this Warrant is at all times equal to or less than
the Warrant Price then in effect.

                                       10
<PAGE>

            8.4 Notices of Certain Actions. The Company shall give written
notice to the Holder in the event (A) the Company closes its books or takes a
record (1) with respect to any dividend or distribution upon the Common Stock,
or for the purpose of entitling or enabling any stockholder to receive any other
right, or (2) with respect to any pro rata subscription offer to holders of
Common Stock, or (B) of any recapitalization, reorganization, reclassification,
consolidation, merger, dissolution, liquidation or sale of all or substantially
all of the Company's assets or other transaction which is effected in such a way
that holders of Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities, cash or assets with respect to or in
exchange for Common Stock. Such notice shall be sent at least ten days prior to
the record date or effective date for the event specified in such notice.

            SECTION 9. NOTICES. Any notice or other document required or
permitted to be given or delivered to the Holder shall be delivered at, or sent
by certified or registered mail to, the Holder at such address as shall have
been furnished to the Company in writing by the Holder. Any notice or other
document required or permitted to be given or delivered to the Company shall be
delivered at, or sent by certified or registered mail to, the Company at its
address for notices set forth on the signature page hereto or to such other
address as shall have been furnished in writing to the Holder by the Company.
Any notice so addressed and mailed by registered or certified mail shall be
deemed to be given when so mailed. Any notice so addressed and otherwise
delivered shall be deemed to be given when actually received by the addressee.

            SECTION 10. NO RIGHTS AS STOCKHOLDER; LIMITATION OF LIABILITY. This
Warrant shall not entitle the Holder to any of the rights of a stockholder of
the Company (including, without limitation, any preemption rights, voting rights
or rights to dividends) except upon exercise in accordance with the terms
hereof. Notwithstanding the foregoing, in the event (i) the Company effects a
split of the Common Stock by means of a stock dividend and the Warrant Price of
and the number of Warrant Shares are adjusted as of the date of the distribution
of the dividend (rather than as of the record date for such dividend), and (ii)
the Holder exercises this Warrant between the record date and the distribution
date for such stock dividend, the Holder shall be entitled to receive, on the
distribution date, the stock dividend with respect to the shares of Common Stock
acquired upon such exercise, notwithstanding the fact that such shares were not
outstanding as of the close of business on the record date for such stock
dividend. No provision hereof, in the absence of affirmative action by the
Holder to purchase shares of Common Stock, and no mere enumeration herein of the
rights or privileges of the Holder, shall give rise to any liability of the
Holder for the Warrant Price hereunder or as a stockholder of the Company,
whether such liability is asserted by the Company or by creditors of the
Company.

            SECTION 11. GOVERNING LAW. THE VALIDITY, INTERPRETATION, AND
ENFORCEMENT OF THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF DELAWARE WITHOUT GIVING EFFECT TO THE CONFLICT OF
LAW PRINCIPLES THEREOF.

            SECTION 12. WARRANT REGISTER. The Company shall maintain at its
principal executive offices books for the registration and the registration of
transfer of Warrants. The Holder may change its address as shown on the warrant
register by written notice to the Company requesting such change.

                                       11
<PAGE>

            SECTION 13. AMENDMENTS. This Warrant and any provision hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the Holder and the Company. The headings in this Warrant are for
purposes of reference only and shall not affect the meaning or construction of
any of the provisions hereof.

hereof at any time and from time to time during the Term of this Warrant: (i)

            In the event of any exercise of the rights represented by this
Warrant, a certificate or certificates for the shares of Common Stock so
purchased, registered in the name of the Holder or, subject to compliance with

<PAGE>

exercised; and, unless this Warrant has expired, a new Warrant representing the
number of shares with respect to which this Warrant shall not then have been
exercised shall also be issued to the Holder hereof within such time. The person
in whose name any certificate for shares of Common Stock is issued upon exercise
of this Warrant shall for all purposes be deemed to have become the holder of
record of such shares on the date on which the Holder shall have complied with
the conditions for exercise of this Warrant set forth above, irrespective of the
date of delivery of such certificate, except that, if the date of such
compliance is a date when the stock transfer books of the Company are closed,
such person shall be deemed to have become the holder of such shares at the
close of business on the next succeeding date on which the stock transfer books
are open.

            2.2 Transfer Restriction Legend. Each certificate for Warrant Shares
shall bear the following legend (and any additional legend required by (i) any
applicable state securities laws and (ii) any securities exchange upon which
such Warrant Shares may, at the time of such exercise, be listed) on the face
thereof unless at the time of exercise such Warrant Shares shall be registered
under the Securities Act:

            "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
            UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT")
            AND/OR QUALIFIED UNDER ANY STATE SECURITIES LAWS. SUCH SHARES MAY
            NOT be OFFERED OR sold or transferred EXCEPT (A) PURSUANT TO AN
            EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND
            REGISTRATION AND/OR QUALIFICATION UNDER APPLICABLE STATE SECURITIES
            LAWS, (B) IN A TRANSACTION WHICH IS EXEMPT FROM REGISTRATION UNDER
            THE SECURITIES ACT AND REGISTRATION AND/OR QUALIFICATION UNDER
            APPLICABLE STATE SECURITIES LAWS PROVIDED THAT AT THE ISSUER'S
            REQUEST, THE TRANSFEROR THEREOF SHALL HAVE DELIVERED TO THE ISSUER
            AN OPINION OF COUNSEL (WHICH OPINION SHALL BE IN FORM, SUBSTANCE AND
            SCOPE REASONABLY SATISFACTORY TO THE ISSUER FROM COUNSEL REASONABLY
            SATISFACTORY TO THE ISSUER) TO THE EFFECT THAT SUCH SECURITIES MAY
            BE SOLD OR TRANSFERRED PURSUANT TO AN EXEMPTION FROM SUCH
            REGISTRATION, OR (C) SUCH SECURITIES MAY BE SOLD PURSUANT TO RULE
            144 PROMULGATED UNDER THE SECURITIES ACT."

            Any certificate issued at any time in exchange or substitution for
any certificate bearing such legend shall also bear such legend unless, in the
opinion of counsel for the Holder thereof (which counsel shall be satisfactory
to the Company) the securities represented thereby are not, at such time,
required by law to bear such legend. The foregoing legend shall be removed from
the certificates representing any Warrant Shares, at the request of the Holder

                                       3

<PAGE>

thereof, at such time as they become eligible for resale pursuant to Rule
144(k) under the Securities Act or as they have been sold pursuant to a
registration statement declared effective by the Securities and Exchange
Commission or pursuant to Rule 144 under the Securities Act. At the request of
the Company, the Company shall have the right to receive an opinion of counsel
for the Holder, reasonably satisfactory to the Company, to the effect that the
transfer of the Warrant Shares is exempt from the registration requirements of
the Securities Act, prior to the removal of the legend if the request for
removal is being made pursuant to Rule 144 or Rule 144(k) under the Securities
Act.

      SECTION 3. COVENANTS AS TO COMMON STOCK. The Company shall at all times
reserve and keep available out of its authorized but unissued Common Stock (or
out of shares of Common Stock held in its treasury) solely for the purpose of
issuance upon the exercise of this Warrant, the maximum number of Warrant Shares
issuable upon the exercise of this Warrant. The Company covenants and agrees
that all shares of Common Stock that may be issued upon the exercise of the
rights represented by this Warrant shall, upon issuance, be validly issued,
fully paid and nonassessable, and free from all taxes, liens, preemptive rights
and charges with respect to the issue thereof. The Company shall take all such
actions as may be necessary to ensure that all such Warrant Shares may be so
issued without violation by the Company of any applicable law or governmental
regulation or any requirements of any domestic securities exchange or quotation
system upon which shares of Common Stock or other securities constituting
Warrant Shares may be listed or quoted (except for official notice of issuance
which shall be immediately delivered by the Company upon each such issuance).
The Company further covenants and agrees that it shall pay when due and payable
any and all federal and state documentary or stamp taxes (other than federal or
state income taxes) which may be payable in respect of the issue of this Warrant
or any Common Stock or certificates therefor issuable upon the exercise of this
Warrant, except that, if Warrant Shares or new Warrants shall be registered in a
name or names other than the name of the Holder, funds sufficient to pay all
transfer taxes payable as a result of such transfer shall be paid by the Holder
at the time of delivery of the Notice of Exercise.

      SECTION 4. ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment of the
Warrant Price as provided in Section 5(a), Section 5(b), Section 5(c) or Section
5(f), the number of Warrant Shares shall be changed to the number determined by
multiplying the Warrant Price in effect immediately prior to such adjustment by
the number of Warrant Shares purchasable immediately prior to such adjustment
and dividing the product thereof by the Warrant Price resulting from such
adjustment.

      SECTION 5. ADJUSTMENT. The Warrant Price and terms of the Warrant shall be
subject to adjustment from time to time as follows:

            (a) If, at any time during the Term of this Warrant, the Company
   shall make or issue, a dividend or other distribution payable in additional
   shares of Common Stock, then and in each such event the Warrant Price then in
   effect immediately before such event shall be decreased as of the time of
   such issuance by multiplying the Warrant Price then in effect by a fraction:

                                        4

<PAGE>

                        (1) the numerator of which shall be the total number of
shares of Common Stock issued and outstanding immediately prior to the time of
such issuance, and

                        (2) the denominator of which shall be the total number
of shares of Common Stock issued and outstanding immediately prior to the time
of such issuance plus the number of shares of Common Stock issuable in payment
of such dividend or distribution.

            (b) If, at any time during the Term of this Warrant, the number of
   shares of Common Stock outstanding is increased by a subdivision or split-up
   of shares of Common Stock, then, immediately after the date fixed for the
   determination of holders of Common Stock entitled to receive shares in such
   subdivision or split-up, the Warrant Price in effect immediately before the
   subdivision or split-up shall be appropriately decreased so that the number
   of shares of Common Stock issuable upon the exercise hereof shall be
   increased in proportion to such increase in outstanding shares.

            (c) If, at any time during the Term of this Warrant, the number of
   shares of Common Stock outstanding is decreased by a combination of the
   outstanding shares of Common Stock or reverse stock split, then, immediately
   after the effective date for such combination, the Warrant Price in effect
   immediately prior to such combination or reverse stock split shall be
   appropriately increased so that the number of shares of Common Stock issuable
   upon the exercise hereof shall be decreased in proportion to such decrease in
   outstanding shares.

            (d) If, at any time during the Term of this Warrant, the Company
   shall make or issue, or fix a record date for the determination of holders of
   Common Stock entitled to receive, a dividend or other distribution payable in
   securities of the Company (other than shares of Common Stock) or in cash or
   other property (other than dividends or distributions for which an adjustment
   is made pursuant to other provisions of this Section 5 or regular cash
   dividends paid out of earnings or earned surplus, determined in accordance
   with generally accepted accounting principles), then and in each such event
   provision shall be made so that the Holder shall receive upon the exercise
   hereof, in addition to the number of shares of Common Stock issuable
   hereunder, the kind and amount of securities of the Company, cash or other
   property which the Holder would have been entitled to receive had this
   Warrant been exercised on the effective date fixed for the determination of
   holders of Common Stock entitled to receive a dividend or distribution in
   such event and had the Holder thereafter, during the period from such date to
   and including the exercise date, retained any such securities receivable
   during such period, giving application to all adjustments called for during
   such period under this Section 5 with respect to the rights of the Holder.

            (e) In the case of any proposed consolidation or merger of the
   Company with another entity, or the proposed sale of all or substantially all
   of its assets to another person or entity, or any proposed consolidation,
   reorganization, recapitalization, or reclassification of the capital stock of
   the Company or other transaction, then, as a condition of such consolidation,
   merger, sale, consolidation, reorganization, recapitalization,
   reclassification or other transaction, the Company shall give 30 days' prior
   written notice thereof to the Holder

                                        5

<PAGE>

   hereof and lawful and adequate provision shall be made whereby the Holder
   shall thereafter have the right to receive upon the basis and upon the terms
   and conditions specified herein, in lieu of the Warrant Shares immediately
   theretofore purchasable hereunder, such shares of stock, securities, cash or
   assets as may (by virtue of such consolidation, merger, sale, consolidation,
   reorganization, recapitalization, reclassification or other transaction) be
   issued or payable with respect to or in exchange for the number of Warrant
   Shares purchasable hereunder immediately before such consolidation, merger,
   sale, reorganization, recapitalization, reclassification or other
   transaction. In any such case appropriate provision shall be made with
   respect to the rights and interests of the Holder to the end that the
   provisions hereof shall thereafter be applicable as nearly as may be
   practicable, in relation to any shares of stock, securities, cash or assets
   thereafter deliverable upon the exercise of this Warrant. Notwithstanding the
   foregoing sentences, if (x) there shall occur any consolidation, merger,
   sale, consolidation, reorganization, recapitalization or other transaction in
   which the Common Stock is converted into or exchanged for anything other than
   solely equity securities, and (y) the common stock of the acquiring or
   surviving company (which shall be understood to mean the ultimate parent of
   such company, if such company is not publicly traded and its ultimate parent
   is publicly traded) is publicly traded, then, as part of such consolidation,
   merger, sale, consolidation, reorganization, recapitalization,
   reclassification or other transaction, (i) the Holder shall have the right
   thereafter to receive upon the exercise hereof such number of shares of
   common stock of the acquiring or surviving company as is determined by
   multiplying (A) the number of shares of Common Stock subject to this Warrant
   immediately prior to such consolidation, merger, sale, consolidation,
   reorganization, recapitalization, reclassification or other transaction by
   (B) a fraction, the numerator of which is the Fair Market Value (as defined
   below) per share of Common Stock as of the effective date of such
   consolidation, merger, sale, consolidation, reorganization, recapitalization,
   reclassification or other transaction, as determined pursuant to Section 7,
   and the denominator of which is the fair market value per share of common
   stock of the acquiring or surviving company as of the effective date of such
   transaction, as determined in good faith by the Board of Directors of the
   Company (using the principles set forth in Section 7 to the extent
   applicable), and (ii) the exercise price per share of common stock of the
   acquiring or surviving company shall be the Warrant Price divided by the
   fraction referred to in clause (B) above. The Company shall not effect any
   such consolidation, merger, sale, reorganization, recapitalization,
   reclassification or other transaction unless, prior to the consummation
   thereof, the successor entity (if other than the Company) resulting from such
   consolidation, merger, sale, reorganization, recapitalization,
   reclassification or other transaction (including a purchaser of all or
   substantially all the Company's assets) assumes by written instrument the
   obligation to deliver to each Holder of Warrants such shares of stock,
   securities, cash or assets as, in accordance with the foregoing provisions,
   such Holder may be entitled to acquire upon exercise of Warrants.

            (f) If at any time the Company shall issue or sell any Common Stock
   (other than Common Stock issued (a) pursuant to the Company's existing or
   future stock option plans or pursuant to any other existing or future Common
   Stock related director or employee compensation plan of the Company approved
   by the board of directors of the Company (the "BOARD OF DIRECTORS"), (b) as
   consideration for the acquisition of a business or of assets, (c) to the
   Company's joint venture partners in exchange for interests in the relevant
   joint venture, (d) upon conversion of any shares of any series of preferred
   stock or as the payment

                                        6

<PAGE>

   of a dividend with respect to any series of preferred stock outstanding on
   the date hereof or the issuance of which caused an adjustment under the other
   provisions of this Section 5 or (e) upon the exercise or conversion of any
   security the issuance of which caused an adjustment under the other
   provisions of this Section 5 for a consideration per share less than the
   Warrant Price then in effect, or shall issue any options, rights, warrants or
   other securities convertible into or exercisable or exchangeable for Common
   Stock (other than such securities paid as dividends on any class of preferred
   stock outstanding on the date hereof or the issuance of which caused an
   adjustment under the other provisions of this Section 5) having a conversion,
   exercise or exchange price, together with the issue price of such securities,
   per share of Common Stock less than the Warrant Price then in effect, the
   Warrant Price to be in effect after such issuance or sale shall be determined
   by multiplying the Warrant Price in effect immediately prior to such issuance
   or sale by a fraction, (i) the denominator of which shall be the sum of (w)
   the number of shares of Common Stock outstanding immediately prior to such
   issuance or sale plus (x) the number of additional shares of Common Stock to
   be issued or sold (or, in the case of any options, rights, warrants or other
   convertible, exercisable or exchangeable securities, issued on conversion,
   exercise or exchange), and (ii) the numerator of which shall be the sum of
   (y) the number of shares of Common Stock outstanding immediately prior to
   such issuance and sale plus (z) the number of shares of Common Stock which
   the aggregate consideration received by the Company for the total number of
   additional shares of Common Stock so issued or sold (or issuable on
   conversion, exercise or exchange) would purchase at the Warrant Price in
   effect on the date of such issuance or sale. In case any portion of the
   consideration to be received by the Company shall be in a form other than
   cash, the fair market value (determined in accordance with the principles set
   forth in Section 7 to the extent applicable) of such non-cash consideration
   shall be utilized in the foregoing computation. Such adjustment shall be made
   successively whenever any such issuance or sale is made, and shall become
   effective immediately after such issuance or sale. If all the Common Stock
   deliverable upon exercise, conversion or exchange of securities convertible
   into Common Stock have not been issued when such securities are no longer
   outstanding, then the Warrant Price shall promptly be readjusted to the
   Warrant Price which would then be in effect had the adjustment upon the
   issuance of such securities been made on the basis of the actual number of
   Common Stock issued upon conversion, exercise or exchange of such securities.

            (g) Whenever the Warrant Price shall be adjusted as provided in this
   Section 5, the Company shall promptly prepare a statement showing the facts
   requiring such adjustment and the Warrant Price and number of Warrant Shares
   that shall be in effect after such adjustment, setting forth in reasonable
   detail and certifying the calculation of such adjustment. The Company shall
   cause a copy of such statement to be sent by mail, first class postage
   prepaid, to each Holder at its, his or her address appearing on the Company's
   records. The Company shall, as promptly as reasonably practicable after the
   written request at any time of the Holder (but in any event not later than 10
   days thereafter), furnish or cause to be furnished to the Holder a
   certificate setting forth (i) the Warrant Price then in effect and (ii) the
   number of shares of Common Stock and the amount, if any, of other securities,
   cash or property which then would be received upon the exercise of this
   Warrant.

            (h) Adjustments made pursuant to this Section 5 shall be made on the
   date such dividend, subdivision, split-up, reverse stock split, combination,
   distribution, issuance,

                                        7

<PAGE>

   sale, consolidation, reorganization, recapitalization, reclassification or
   other transaction, as the case may be, is made, and shall become effective at
   the close of business on the day such event becomes effective.

      SECTION 6. OWNERSHIP.

            6.1 Ownership of Warrant. The Company may deem and treat the person
   in whose name this Warrant is registered as the holder and owner hereof
   (notwithstanding any notations of ownership or writing hereon made by anyone
   other than the Company) for all purposes and shall not be affected by any
   notice to the contrary until presentation of this Warrant for registration of
   transfer as provided in this Section 6.

            6.2 Transfer and Replacement.

            (a) No Holder shall Transfer this Warrant other than (i) a Transfer
   to one or more of its Affiliates or (ii) if the Company first shall have been
   furnished with an opinion of legal counsel, reasonably satisfactory to the
   Company, to the effect that such Transfer is exempt from the registration
   requirements of the Securities Act. Notwithstanding the foregoing, no
   registration or opinion of counsel shall be required for, and a Transfer
   shall be permitted in the event of, a Transfer by a Holder which is a
   partnership to a partner of such partnership or a retired partner of such
   partnership or to the estate of any such partner or retired partner, or a
   Transfer by a Holder which is a limited liability company to a member of such
   limited liability company or a retired member or to the estate of any such
   member or retired member, provided that the transferee in each case agrees in
   writing to be subject to the terms of this Section 6. Any attempt to Transfer
   this Warrant other than in accordance with this Section 6 shall be null and
   void and no right, title or interest in or to such Warrant shall be
   Transferred to the purported transferee, buyer, donee, assignee or
   encumbrance holder. The Company will not give, and will not permit the
   Company's transfer agent to give, any effect to such attempted Transfer in
   its stock records.

            (b) Subject to Section 6.2(a), this Warrant and all rights hereunder
   are transferable in whole or in part upon the books of the Company by the
   Holder hereof in person or by duly authorized attorney, together with a
   properly executed Assignment (in the form of Exhibit B or Exhibit C hereto,
   as the case may be) and a new Warrant or Warrants, of the same tenor as this
   Warrant but registered in the name of the transferee or transferees (and in
   the name of the Holder, if a partial transfer is effected) shall be promptly
   made and delivered by the Company upon surrender of this Warrant duly
   endorsed, at the office of the Company referred to in Section 9 hereof. Upon
   receipt by the Company of evidence reasonably satisfactory to it of the loss,
   theft or destruction, and, in such case, of indemnity or security reasonably
   satisfactory to it, and upon surrender of this Warrant if mutilated, the
   Company shall promptly make and deliver a new Warrant of like tenor, in lieu
   of this Warrant. This Warrant shall be promptly cancelled by the Company upon
   the surrender hereof in connection with any transfer or replacement. Except
   as otherwise provided above, in the case of the loss, theft or destruction of
   a Warrant, the Company shall pay all expenses, taxes and other charges
   payable in connection with any transfer or replacement of this Warrant, other
   than documentary or stamp taxes (if any) payable in connection with a
   transfer of this Warrant, which shall be payable by the Holder. The Holder
   shall not transfer this Warrant and the rights hereunder except in compliance
   with federal and state securities laws.

                                        8

      SECTION 7. FRACTIONAL SHARES. Fractional shares shall not be issued upon
the exercise of this Warrant but in any case where the Holder would, except for
the provisions of this Section 7, be entitled under the terms hereof to receive
a fractional share upon the complete exercise of this Warrant, the Company
shall, upon the exercise of this Warrant for the largest number of whole shares
then called for, pay a sum in cash equal to the excess of the Fair Market Value
of such fractional share over the Warrant Price for such fractional share on the
exercise date.

            (a) The Fair Market Value per share of Common Stock shall be
   determined as follows:

                  (i) If the Common Stock is listed on a national securities
exchange, the Nasdaq National Market or another nationally recognized trading
system as of the exercise date, the Fair Market Value per share of Common Stock
shall be deemed to be the average of the high and low reported sale prices per
share of Common Stock thereon on the trading day immediately preceding the
effective date or the exercise date, as applicable (provided that if no such
price is reported on such day, the Fair Market Value per share of Common Stock
shall be determined pursuant to clause (ii)).

                  (ii) If the Common Stock is not listed on a national
securities exchange, the Nasdaq National Market or another nationally recognized
trading system as of the effective date or the exercise date, as applicable, the
Fair Market Value per share of Common Stock shall be deemed to be the amount
most recently determined by the Board to represent the fair market value per
share of the Common Stock (including without limitation a determination for
purposes of granting Common Stock options or issuing Common Stock under any
plan, agreement or arrangement with employees of the Company); and, upon request
of the Holder, the Board (or a representative thereof) shall, as promptly as
reasonably practicable but in any event not later than 3 Business Days after
such request, notify the Holder of the Fair Market Value per share of Common
Stock and furnish the Holder with reasonable documentation of the Board's
determination of such Fair Market Value. Notwithstanding the foregoing, if the
Board has not made such a determination within the three-month period prior to
the exercise date, then (A) the Board shall make, and shall provide or cause to
be provided to the Holder notice of, a determination of the Fair Market Value
per share of the Common Stock within 15 days of a request by the Holder that it
do so, and (B) payment in cash with respect to any fractional share as required
by Section 7 hereof shall be delayed until such determination is made and notice
thereof is provided to the Holder (it being understood that this shall not
prevent the Holder, at its option, from exercising the Warrant prior to such
determination).

      SECTION 8. SPECIAL ARRANGEMENTS OF THE COMPANY. The Company covenants and
agrees that during the Term of this Warrant, unless otherwise approved by the
Holder:

            8.1 Certain Actions. The Company shall not amend its charter to
eliminate as an authorized class of capital stock that class denominated as
"Common Stock" on the date hereof. The Company shall not by any action avoid or
seek to avoid the observance

                                        9

<PAGE>

or performance of any terms of this Warrant or impair or diminish its value, but
shall at all times in good faith assist in the carrying out of all such terms of
Warrant. Without limiting the generality of the foregoing, the Company shall
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.

            8.2 Shall Bind Successors. This Warrant and the rights evidenced
hereby shall be binding upon the Company and its successors and assigns and
shall inure to the benefit of the Holder and its permitted assigns to the extent
permitted by Section 6.2.

            8.3 No Exercise Interference; Par Value. Other than in accordance
with Section 6.2, the Company shall not close its books against the transfer of
this Warrant or of any Warrant Shares issued or issuable upon the exercise of
this Warrant in any manner which interferes with the timely exercise of this
Warrant. The Company shall from time to time take all such action as may be
necessary to assure that the par value per share of the unissued Warrant Shares
acquirable upon exercise of this Warrant is at all times equal to or less than
the Warrant Price then in effect.

            8.4 Notices of Certain Actions. The Company shall give written
notice to the Holder in the event (A) the Company closes its books or takes a
record (1) with respect to any dividend or distribution upon the Common Stock,
or for the purpose of entitling or enabling any stockholder to receive any other
right, or (2) with respect to any pro rata subscription offer to holders of
Common Stock, or (B) of any recapitalization, reorganization, reclassification,
consolidation, merger, dissolution, liquidation or sale of all or substantially
all of the Company's assets or other transaction which is effected in such a way
that holders of Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities, cash or assets with respect to or in
exchange for Common Stock. Such notice shall be sent at least ten days prior to
the record date or effective date for the event specified in such notice.

      SECTION 9. NOTICES. Any notice or other document required or permitted to
be given or delivered to the Holder shall be delivered at, or sent by certified
or registered mail to, the Holder at such address as shall have been furnished
to the Company in writing by the Holder. Any notice or other document required
or permitted to be given or delivered to the Company shall be delivered at, or
sent by certified or registered mail to, the Company at its address for notices
set forth on the signature page hereto or to such other address as shall have
been furnished in writing to the Holder by the Company. Any notice so addressed
and mailed by registered or certified mail shall be deemed to be given when so
mailed. Any notice so addressed and otherwise delivered shall be deemed to be
given when actually received by the addressee.

      SECTION 10. NO RIGHTS AS STOCKHOLDER; LIMITATION OF LIABILITY. This
Warrant shall not entitle the Holder to any of the rights of a stockholder of
the Company (including, without limitation, any preemption rights, voting rights
or rights to dividends) except upon exercise in accordance with the terms
hereof. Notwithstanding the foregoing, in the event (i) the Company effects a
split of the Common Stock by means of a stock dividend and the Warrant Price of
and the number of Warrant Shares are adjusted as of the date of the distribution
of the dividend (rather than as of the record date for such dividend), and (ii)
the Holder exercises this Warrant

                                       10

<PAGE>

between the record date and the distribution date for such stock dividend, the
Holder shall be entitled to receive, on the distribution date, the stock
dividend with respect to the shares of Common Stock acquired upon such exercise,
notwithstanding the fact that such shares were not outstanding as of the close
of business on the record date for such stock dividend. No provision hereof, in
the absence of affirmative action by the Holder to purchase shares of Common
Stock, and no mere enumeration herein of the rights or privileges of the Holder,
shall give rise to any liability of the Holder for the Warrant Price hereunder
or as a stockholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

      SECTION 11. GOVERNING LAW. THE VALIDITY, INTERPRETATION, AND ENFORCEMENT
OF THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF DELAWARE WITHOUT GIVING EFFECT TO THE CONFLICT OF LAW PRINCIPLES
THEREOF.

      SECTION 12. WARRANT REGISTER. The Company shall maintain at its principal
executive offices books for the registration and the registration of transfer of
Warrants. The Holder may change its address as shown on the warrant register by
written notice to the Company requesting such change.

      SECTION 13. AMENDMENTS. This Warrant and any provision hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the Holder and the Company. The headings in this Warrant are for
purposes of reference only and shall not affect the meaning or construction of
any of the provisions hereof.
