                           ADDITIONAL INVESTMENT RIGHT

                 TO PURCHASE 3,529,412 SHARES OF COMMON STOCK OF

                               WAVE SYSTEMS CORP.

         THIS ADDITIONAL INVESTMENT RIGHT (the "Additional Investment Right")
certifies that, for value received, Capital Ventures International (the
"Holder"), is entitled, upon the terms and subject to the limitations on
exercise and the conditions hereinafter set forth, at any time beginning 5
trading days prior to and ending on the 90-day anniversary of the Closing Date
(the "Termination Date") but not thereafter, to subscribe for and purchase from
Wave Systems Corp., a Delaware corporation (the "Company"), up to 3,529,412
shares (the "Additional Investment Right Shares") of Class A Common Stock, par
value $0.01 per share, of the Company (the "Common Stock"). The purchase price
of one share of Common Stock (the "Exercise Price") under this Additional
Investment Right shall be $1.00 (100% of Market Price), subject to adjustment
hereunder.

         Section 1.    Definitions. Capitalized terms used and not otherwise
defined herein shall have the meanings set forth in that certain Securities
Purchase Agreement (the "Purchase Agreement"), dated July 30, 2004, among the
Company and the purchasers signatory thereto.

         Section 2.    Exercise.

                 (a)   EXERCISE OF THE ADDITIONAL INVESTMENT RIGHT. Exercise of
         the purchase rights represented by this Additional Investment Right may
         be made at any time or times beginning 5 trading days prior to and
         ending on the Termination Date by delivery to the Company of a duly
         executed facsimile copy of the Notice of Exercise Form annexed hereto
         (or such other office or agency of the Company as it may designate by
         notice in writing to the registered Holder at the address of such
         Holder appearing on the books of the Company); provided, however,
         within 5 Trading Days after the date said Notice of Exercise is
         delivered to the Company, the Holder shall have surrendered this
         Additional Investment Right to the Company and the Company shall have
         received payment of the aggregate Exercise Price of the shares thereby
         purchased by wire transfer or cashier's check drawn on a United States
         bank.

                 (b)   EXERCISE LIMITATIONS.

                       (i)     HOLDER'S RESTRICTIONS. The Holder shall not have
                 the right to exercise any portion of this Additional Investment
                 Right, pursuant to Section 2(c) or otherwise, to the extent
                 that after giving effect to such issuance after exercise, the
                 Holder (together with the Holder's affiliates), as set forth on
                 the applicable Notice of Exercise, would beneficially own in
                 excess of 9.99% of the number of shares of the Common Stock
                 outstanding immediately after giving effect to such issuance.
                 For purposes of the foregoing sentence, the number of shares of
                 Common Stock beneficially owned by the Holder and its
                 affiliates shall include the number of shares of Common Stock
                 issuable upon exercise of this Additional

<Page>

                 Investment Right with respect to which the determination of
                 such sentence is being made, but shall exclude the number of
                 shares of Common Stock which would be issuable upon (A)
                 exercise of the remaining, nonexercised portion of this
                 Additional Investment Right beneficially owned by the Holder or
                 any of its affiliates and (B) exercise or conversion of the
                 unexercised or nonconverted portion of any other securities of
                 the Company (including, without limitation, any other Warrants
                 or Additional Investment Rights) subject to a limitation on
                 conversion or exercise analogous to the limitation contained
                 herein beneficially owned by the Holder or any of its
                 affiliates. Except as set forth in the preceding sentence, for
                 purposes of this Section 2(b), beneficial ownership shall be
                 calculated in accordance with Section 13(d) of the Exchange
                 Act, it being acknowledged by Holder that the Company is not
                 representing to Holder that such calculation is in compliance
                 with Section 13(d) of the Exchange Act and Holder is solely
                 responsible for any schedules required to be filed in
                 accordance therewith. To the extent that the limitation
                 contained in this Section 2(b) applies, the determination of
                 whether this Additional Investment Right is exercisable (in
                 relation to other securities owned by the Holder) and of which
                 a portion of this Additional Investment Right is exercisable
                 shall be in the sole discretion of such Holder, and the
                 submission of a Notice of Exercise shall be deemed to be such
                 Holder's determination of whether this Additional Investment
                 Right is exercisable (in relation to other securities owned by
                 such Holder) and of which portion of this Additional Investment
                 Right is exercisable, in each case subject to such aggregate
                 percentage limitation, and the Company shall have no obligation
                 to verify or confirm the accuracy of such determination. For
                 purposes of this Section 2(b), in determining the number of
                 outstanding shares of Common Stock, the Holder may rely on the
                 number of outstanding shares of Common Stock as reflected in
                 (x) the Company's most recent Form 10-Q or Form 10-K, as the
                 case may be, (y) a more recent public announcement by the
                 Company or (z) any other notice by the Company or the Company's
                 Transfer Agent setting forth the number of shares of Common
                 Stock outstanding. Upon the written or oral request of the
                 Holder, the Company shall within two Trading Days confirm
                 orally and in writing to the Holder the number of shares of
                 Common Stock then outstanding. In any case, the number of
                 outstanding shares of Common Stock shall be determined after
                 giving effect to the conversion or exercise of securities of
                 the Company, including this Additional Investment Right, by the
                 Holder or its affiliates since the date as of which such number
                 of outstanding shares of Common Stock was reported.

                       (ii)    TRADING MARKET RESTRICTIONS. If the Company has
                 not obtained Shareholder Approval (as defined below), if
                 required, then the Company may not issue upon exercise of this
                 Additional Investment Right in the aggregate, in excess of
                 19.999% of the number of shares of Common Stock outstanding on
                 the Trading Day immediately preceding the Closing Date, less
                 any shares of Common Stock issued upon the Closing Date or upon
                 prior exercise of this or any other Additional Investment Right
                 or Warrant issued pursuant to the Purchase Agreement (such
                 number of shares, the "Issuable Maximum"). If on any attempted
                 exercise of this Additional Investment Right, the issuance of
                 Additional

2
<Page>

                 Investment Right Shares would exceed the Issuable Maximum and
                 the Company shall not have previously obtained the vote of
                 shareholders (the "Shareholder Approval"), if any, as may be
                 required by the applicable rules and regulations of the
                 Principal Market (or any successor entity) to approve the
                 issuance of shares of Common Stock in excess of the Issuable
                 Maximum pursuant to the terms hereof, then the Company shall
                 issue to the Holder requesting an Additional Investment Right
                 exercise such number of Additional Investment Right Shares as
                 may be issued below the Issuable Maximum and, with respect to
                 the remainder of the aggregate number of Additional Investment
                 Right Shares, this Additional Investment Right shall not be
                 exercisable until and unless Shareholder Approval has been
                 obtained.

                 (c)   MECHANICS OF EXERCISE.

                       (i)     AUTHORIZATION OF ADDITIONAL INVESTMENT RIGHT
                 SHARES. The Company covenants that all Additional Investment
                 Right Shares which may be issued upon the exercise of the
                 purchase rights represented by this Additional Investment Right
                 will, upon exercise of the purchase rights represented by this
                 Additional Investment Right, be duly authorized, validly
                 issued, fully paid and nonassessable and free from all taxes,
                 liens and charges in respect of the issue thereof (other than
                 taxes in respect of any transfer occurring contemporaneously
                 with such issue). The Company covenants that during the period
                 the Additional Investment Right is outstanding, it will reserve
                 from its authorized and unissued Common Stock a sufficient
                 number of shares to provide for the issuance of the Additional
                 Investment Right Shares upon the exercise of any purchase
                 rights under this Additional Investment Right. The Company
                 further covenants that its issuance of this Additional
                 Investment Right shall constitute full authority to its
                 officers who are charged with the duty of executing stock
                 certificates to execute and issue the necessary certificates
                 (or to authorize an uncertificated issuance to the Holder via
                 the DTC DWAC system) for the Additional Investment Right Shares
                 upon the exercise of the purchase rights under this Additional
                 Investment Right. The Company will take all such reasonable
                 action as may be necessary to assure that such Additional
                 Investment Right Shares may be issued as provided herein
                 without violation of any applicable law or regulation, or of
                 any requirements of the Trading Market upon which the Common
                 Stock may be listed.

                       (ii)    DELIVERY OF CERTIFICATES UPON EXERCISE.
                 Certificates (or DWAC transfers) for shares purchased hereunder
                 shall be delivered to the Holder within 3 Trading Days from the
                 receipt by the Company of the Notice of Exercise Form,
                 surrender of this Additional Investment Right and payment of
                 the aggregate Exercise Price as set forth above ("Additional
                 Investment Right Share Delivery Date"). This Additional
                 Investment Right shall be deemed to have been exercised on the
                 date the Exercise Price is received by the Company. The
                 Additional Investment Right Shares shall be deemed to have been
                 issued, and Holder or any other person so designated to be
                 named therein shall be deemed to have become a

3
<Page>

                 holder of record of such shares for all purposes, as of the
                 date the Additional Investment Right has been exercised by
                 payment to the Company of the Exercise Price and all taxes
                 required to be paid by the Holder, if any, pursuant to Section
                 2(c)(vii) prior to the issuance of such shares, have been paid.

                       (iii)   DELIVERY OF RESIDUAL ADDITIONAL INVESTMENT RIGHTS
                 UPON PARTIAL EXERCISE. If this Additional Investment Right
                 shall have been exercised in part, the Company shall, at the
                 time of delivery of the certificate or certificates
                 representing Additional Investment Right Shares, deliver to
                 Holder a new Additional Investment Right evidencing the rights
                 of Holder to purchase the unpurchased Additional Investment
                 Right Shares called for by this Additional Investment Right,
                 which new Additional Investment Right shall in all other
                 respects be identical with this Additional Investment Right.

                       (iv)    RESCISSION RIGHTS. If the Company fails to
                 deliver to the Holder a certificate or certificates (or DWAC
                 transfer) representing the Additional Investment Right Shares
                 pursuant to this Section 2(c)(iv) by the Additional Investment
                 Right Share Delivery Date, then the Holder will have the right
                 to rescind such exercise.

                       (v)     BUY-IN COMPENSATION. In addition to any other
                 rights available to the Holder, if the Company fails to deliver
                 to the Holder a certificate or certificates (or DWAC transfer)
                 representing the Additional Investment Right Shares pursuant to
                 an exercise on or before the Additional Investment Right Share
                 Delivery Date, and if after such date the Holder is required by
                 its broker to purchase (in an open market transaction or
                 otherwise) shares of Common Stock to deliver in satisfaction of
                 a sale by the Holder of the Additional Investment Right Shares
                 which the Holder anticipated receiving upon such exercise (a
                 "Buy-In"), then the Company shall (1) pay in cash to the Holder
                 the amount by which (x) the Holder's total purchase price
                 (including brokerage commissions, if any) for the shares of
                 Common Stock so purchased exceeds (y) the amount obtained by
                 multiplying (A) the number of Additional Investment Right
                 Shares that the Company was required to deliver to the Holder
                 in connection with the exercise at issue times (B) the price at
                 which the sell order giving rise to such purchase obligation
                 was executed, and (2) at the option of the Holder, either
                 reinstate the portion of the Additional Investment Right and
                 equivalent number of Additional Investment Right Shares for
                 which such exercise was not honored or deliver to the Holder
                 the number of shares of Common Stock that would have been
                 issued had the Company timely complied with its exercise and
                 delivery obligations hereunder. For example, if the Holder
                 purchases Common Stock having a total purchase price of $11,000
                 to cover a Buy-In with respect to an attempted exercise of
                 shares of Common Stock with an aggregate sale price giving rise
                 to such purchase obligation of $10,000, under clause (1) of the
                 immediately preceding sentence the Company shall be required to
                 pay the Holder $1,000. The Holder shall provide the Company
                 written notice indicating the amounts payable to the Holder in
                 respect of the Buy-In, together with applicable confirmations
                 and other

4
<Page>

                 evidence reasonably requested by the Company. Nothing herein
                 shall limit a Holder's right to pursue any other remedies
                 available to it hereunder, at law or in equity including,
                 without limitation, a decree of specific performance and/or
                 injunctive relief with respect to the Company's failure to
                 timely deliver certificates representing shares of Common Stock
                 upon exercise of the Additional Investment Right as required
                 pursuant to the terms hereof.

                       (vi)    NO FRACTIONAL SHARES OR SCRIP. No fractional
                 shares or scrip representing fractional shares shall be issued
                 upon the exercise of this Additional Investment Right. As to
                 any fraction of a share which Holder would otherwise be
                 entitled to purchase upon such exercise, the Company shall pay
                 a cash adjustment in respect of such final fraction in an
                 amount equal to such fraction multiplied by the Exercise Price.

                       (vii)   CHARGES, TAXES AND EXPENSES. Issuance of
                 certificates for Additional Investment Right Shares shall be
                 made without charge to the Holder for any issue or transfer tax
                 or other incidental expense in respect of the issuance of such
                 certificate, all of which taxes and expenses shall be paid by
                 the Company, and such certificates shall be issued in the name
                 of the Holder or in such name or names as may be directed by
                 the Holder; provided, however, that in the event certificates
                 for Additional Investment Right Shares are to be issued in a
                 name other than the name of the Holder, this Additional
                 Investment Right when surrendered for exercise shall be
                 accompanied by the Assignment Form attached hereto duly
                 executed by the Holder; and the Company may require, as a
                 condition thereto, the payment of a sum sufficient to reimburse
                 it for any transfer tax incidental thereto.

                       (viii)  CLOSING OF BOOKS. The Company will not close its
                 stockholder books or records in any manner which prevents the
                 timely exercise of this Additional Investment Right, pursuant
                 to the terms hereof.

         Section 3.    Certain Adjustments.

                 (a)   STOCK DIVIDENDS AND SPLITS. If the Company, at any time
         while this Additional Investment Right is outstanding: (A) pays a stock
         dividend or otherwise make a distribution or distributions on shares of
         its Common Stock or any other equity or equity equivalent securities
         payable in shares of Common Stock (which, for avoidance of doubt, shall
         not include any shares of Common Stock issued by the Company pursuant
         to this Additional Investment Right), (B) subdivides outstanding shares
         of Common Stock into a larger number of shares, (C) combines (including
         by way of reverse stock split) outstanding shares of Common Stock into
         a smaller number of shares, or (D) issues by reclassification of shares
         of the Common Stock any shares of capital stock of the Company, then in
         each case the Exercise Price shall be multiplied by a fraction of which
         the numerator shall be the number of shares of Common Stock (excluding
         treasury shares, if any) outstanding before such event and of which the
         denominator shall be the number of shares of Common Stock outstanding
         after such event. Any adjustment made pursuant to this Section 3(a)
         shall become effective immediately after the record date for

5
<Page>

         the determination of stockholders entitled to receive such dividend or
         distribution and shall become effective immediately after the effective
         date in the case of a subdivision, combination or re-classification.

                 (b)   CALCULATIONS. All calculations under this Section 3 shall
         be made to the nearest cent or the nearest 1/100th of a share, as the
         case may be. For purposes of this Section 3, the number of shares of
         Common Stock outstanding as of a given date shall be the sum of the
         number of shares of Common Stock (excluding treasury shares, if any)
         outstanding.

                 (c)   NOTICE TO HOLDERS.

                       (i)     ADJUSTMENT TO EXERCISE PRICE. Whenever the
                 Exercise Price is adjusted pursuant to this Section 3, the
                 Company shall promptly mail to each Holder a notice setting
                 forth the Exercise Price after such adjustment and setting
                 forth a brief statement of the facts requiring such adjustment.

                       (ii)    NOTICE TO ALLOW EXERCISE BY HOLDER. If (A) the
                 Company shall declare a dividend (or any other distribution) on
                 the Common Stock; (B) the Company shall declare a special
                 nonrecurring cash dividend on or a redemption of the Common

                 holders of the Common Stock rights or warrants to subscribe for
                 or purchase any shares of capital stock of any class or of any
                 rights; (D) the approval of any stockholders of the Company
                 shall be required in connection with any reclassification of
                 the Common Stock, any consolidation or merger to which the
                 Company is a party, any sale or transfer of all or
                 substantially all of the assets of the Company, of any
                 compulsory share exchange whereby the Common Stock is converted
                 into other securities, cash or property; (E) the Company shall
                 authorize the voluntary or involuntary dissolution, liquidation

                 last addresses as it shall appear upon the Additional
                 Investment Right Register of the Company, at least 20 calendar
                 days prior to the applicable record or effective date
                 hereinafter specified, a notice stating (x) the date on which a
                 record is to be taken for the purpose of such dividend,
                 distribution, redemption, rights or warrants, or if a record is
                 not to be taken, the date as of which the holders of the Common
                 Stock of record to be entitled to such dividend, distributions,
                 redemption, rights or warrants are to be determined or (y) the
                 date on which such reclassification, consolidation, merger,
                 sale, transfer or share exchange is expected to become
                 effective or close, and the date as of which it is expected
                 that holders of the Common Stock of record shall be entitled to
                 exchange their shares of the Common Stock for securities, cash
                 or other property deliverable upon such reclassification,
                 consolidation, merger, sale, transfer or share exchange;
                 provided, that the failure to mail such notice or any defect
                 therein or in the mailing thereof shall not affect the validity
                 of the corporate action required to be specified in such
                 notice. The Holder is entitled to exercise this Additional
                 Investment Right during

                 the 20-day period commencing the date of such notice to the
                 effective date of the event triggering such notice

         Section 4.    TRANSFER OF THIS ADDITIONAL INVESTMENT RIGHT.

                 (a)   TRANSFERABILITY. Subject to compliance with any
         applicable securities laws and the conditions set forth in Section 5(a)
         hereof, this Additional Investment Right and all rights hereunder are
         transferable, in whole or in part, upon surrender of this Additional
         Investment Right at the principal office of the Company, together with
         a written assignment of this Additional Investment Right substantially
         in the form attached hereto duly executed by the Holder or its agent or
         attorney and funds sufficient to pay any transfer taxes payable upon
         the making of such transfer. Upon such surrender and, if required, such
         payment, the Company shall execute and deliver a new Additional
         Investment Right or Additional Investment Rights in the name of the
         assignee or assignees and in the denomination or denominations
         specified in such instrument of assignment, and shall issue to the
         assignor a new Additional Investment Right evidencing the portion of
         this Additional Investment Right not so assigned, and this Additional
         Investment Right shall promptly be cancelled. An Additional Investment
         Right, if properly assigned, may be exercised by a new holder for the
         purchase of Additional Investment Right Shares without having a new
         Additional Investment Right issued, if exercised in accordance with the
         Additional Investment Right.

                 (b)   COMBINATION OR DIVISION OF ADDITIONAL INVESTMENT RIGHTS.
         This Additional Investment Right may be divided or combined with other
         Additional Investment Rights upon presentation hereof at the aforesaid
         office of the Company, together with a written notice specifying the
         names and denominations in which new Additional Investment Rights are
         to be issued, signed by the Holder or its agent or attorney. Subject to
         compliance with Section 4(a), as to any transfer which may be involved
         in such division or combination, the Company shall execute and deliver
         a new Additional Investment Right or Additional Investment Rights in
         exchange for the Additional Investment Right or Additional Investment
         Rights to be divided or combined in accordance with such notice.

                 (c)   ADDITIONAL INVESTMENT RIGHT REGISTER. The Company shall
         register this Additional Investment Right, upon records to be
         maintained by the Company for that purpose (the "Additional Investment
         Right Register"), in the name of the record Holder hereof from time to
         time. The Company may deem and treat the registered Holder of this
         Additional Investment Right as the absolute owner hereof for the
         purpose of any exercise hereof or any distribution or notice to the
         Holder, and for all other purposes, absent actual notice to the
         contrary.

         Section 5.    Miscellaneous.

                 (a)   TITLE TO THE ADDITIONAL INVESTMENT RIGHT. Prior to the
         Termination Date and subject to compliance with applicable laws and
         Section 4 of this Additional Investment Right, this Additional
         Investment Right and all rights hereunder are transferable, in whole or
         in part, at the office or agency of the Company by the Holder in

7
<Page>

         person or by duly authorized attorney, upon surrender of this
         Additional Investment Right together with the Assignment Form annexed
         hereto properly endorsed.

                 (b)   NO RIGHTS AS SHAREHOLDER UNTIL EXERCISE. This Additional
         Investment Right does not entitle the Holder to any voting rights or
         other rights as a shareholder of the Company prior to the exercise
         hereof. Upon the surrender of this Additional Investment Right and the
         payment of the aggregate Exercise Price, the Additional Investment
         Right Shares so purchased shall be and be deemed to be issued to such
         Holder as the record owner of such shares as of the close of business
         on the later of the date of such surrender or payment.

                 (c)   LOSS, THEFT, DESTRUCTION OR MUTILATION OF ADDITIONAL
         INVESTMENT RIGHT. The Company covenants that upon receipt by the
         Company of evidence reasonably satisfactory to it of the loss, theft,
         destruction or mutilation of this Additional Investment Right or any
         stock certificate relating to the Additional Investment Right Shares,
         and in case of loss, theft or destruction, of indemnity or security
         reasonably satisfactory to it (which, in the case of the Additional
         Investment Right, shall not include the posting of any bond), and upon
         surrender and cancellation of such Additional Investment Right or stock
         certificate, if mutilated, the Company will make and deliver a new
         Additional Investment Right or stock certificate of like tenor and
         dated as of such cancellation, in lieu of such Additional Investment
         Right or stock certificate.

                 (d)   SATURDAYS, SUNDAYS, HOLIDAYS, ETC. If the last or
         appointed day for the taking of any action or the expiration of any
         right required or granted herein shall be a Saturday, Sunday or a legal
         holiday, then such action may be taken or such right may be exercised
         on the next succeeding day not a Saturday, Sunday or legal holiday.

                 (e)   AUTHORIZED SHARES.

                 The Company covenants that during the period the Additional
                 Investment Right is outstanding, it will reserve from its
                 authorized and unissued Common Stock a sufficient number of
                 shares to provide for the issuance of the Additional Investment
                 Right Shares upon the exercise of any purchase rights under
                 this Additional Investment Right. The Company further covenants
                 that its issuance of this Additional Investment Right shall
                 constitute full authority to its officers who are charged with
                 the duty of executing stock certificates to execute and issue
                 the necessary certificates (or authorize an uncertificated
                 issuance to the Holder via the DTC DWAC system) for the
                 Additional Investment Right Shares upon the exercise of the
                 purchase rights under this Additional Investment Right. The
                 Company will take all such reasonable action as may be
                 necessary to assure that such Additional Investment Right
                 Shares may be issued as provided herein without violation of
                 any applicable law or regulation, or of any requirements of the
                 Trading Market upon which the Common Stock may be listed.

                 Except and to the extent as waived or consented to by the
                 Holder, the Company shall not by any action, including, without
                 limitation, amending its certificate of incorporation or
                 through any reorganization, transfer of assets, consolidation,

8
<Page>

                 merger, dissolution, issue or sale of securities or any other
                 voluntary action, avoid or seek to avoid the observance or
                 performance of any of the terms of this Additional Investment
                 Right, but will at all times in good faith assist in the
                 carrying out of all such terms and in the taking of all such
                 actions as may be necessary or appropriate to protect the
                 rights of Holder as set forth in this Additional Investment
                 Right against impairment. Without limiting the generality of
                 the foregoing, the Company will (a) not increase the par value
                 of any Additional Investment Right Shares above the amount
                 payable therefor upon such exercise immediately prior to such
                 increase in par value, (b) take all such action as may be
                 necessary or appropriate in order that the Company may validly
                 and legally issue fully paid and nonassessable Additional
                 Investment Right Shares upon the exercise of this Additional
                 Investment Right, and (c) use commercially reasonable efforts
                 to obtain all such authorizations, exemptions or consents from
                 any public regulatory body having jurisdiction thereof as may
                 be necessary to enable the Company to perform its obligations
                 under this Additional Investment Right.

                 Before taking any action which would result in an adjustment in
                 the number of Additional Investment Right Shares for which this
                 Additional Investment Right is exercisable or in the Exercise
                 Price, the Company shall obtain all such authorizations or
                 exemptions thereof, or consents thereto, as may be necessary
                 from any public regulatory body or bodies having jurisdiction
                 thereof.

                 (f)   JURISDICTION. All questions concerning the construction,
         validity, enforcement and interpretation of this Additional Investment
         Right shall be determined in accordance with the provisions of the
         Purchase Agreement.

                 (g)   NONWAIVER AND EXPENSES. No course of dealing or any delay
         or failure to exercise any right hereunder on the part of Holder shall
         operate as a waiver of such right or otherwise prejudice Holder's
         rights, powers or remedies, notwithstanding that all rights hereunder
         terminate on the Termination Date. If the Company willfully and
         knowingly fails to comply with any provision of this Additional
         Investment Right, which results in any material damages to the Holder,
         the Company shall pay to Holder such amounts as shall be sufficient to
         cover any reasonable costs and expenses including, but not limited to,
         attorneys' fees, including those of appellate proceedings, incurred by
         Holder in collecting any amounts due pursuant hereto or in otherwise
         enforcing any of its rights, powers or remedies hereunder.

                 (h)   NOTICES. Any notice, request or other document required
         or permitted to be given or delivered to the Holder by the Company
         shall be delivered in accordance with the notice provisions of the
         Purchase Agreement.

                 (i)   LIMITATION OF LIABILITY. No provision hereof, in the
         absence of any affirmative action by Holder to exercise this Additional
         Investment Right or purchase Additional Investment Right Shares, and no
         enumeration herein of the rights or privileges of Holder, shall give
         rise to any liability of Holder for the purchase price of any Common

9
<Page>

         Stock or as a stockholder of the Company, whether such liability is
         asserted by the Company or by creditors of the Company.

                 (j)   REMEDIES. 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 Additional
         Investment Right. The Company agrees that monetary damages would not be
         adequate compensation for any loss incurred by reason of a breach by it
         of the provisions of this Additional Investment Right and hereby agrees
         to waive the defense in any action for specific performance that a
         remedy at law would be adequate.

                 (k)   SUCCESSORS AND ASSIGNS. Subject to applicable securities
         laws, this Additional Investment Right and the rights and obligations
         evidenced hereby shall inure to the benefit of and be binding upon the
         successors of the Company and the successors and permitted assigns of
         Holder. The provisions of this Additional Investment Right are intended
         to be for the benefit of all Holders from time to time of this
         Additional Investment Right and shall be enforceable by any such Holder
         or holder of Additional Investment Right Shares.

                 (l)   AMENDMENT. This Additional Investment Right may be
         modified or amended or the provisions hereof waived with the written
         consent of the Company and the Holder.

                 (m)   SEVERABILITY. Wherever possible, each provision of this
         Additional Investment Right shall be interpreted in such manner as to
         be effective and valid under applicable law, but if any provision of
         this Additional Investment Right shall be prohibited by or invalid
         under applicable law, such provision shall be ineffective to the extent
         of such prohibition or invalidity, without invalidating the remainder
         of such provisions or the remaining provisions of this Additional
         Investment Right.

                 (n)   HEADINGS. The headings used in this Additional Investment
         Right are for the convenience of reference only and shall not, for any
         purpose, be deemed a part of this Additional Investment Right.

                              ********************
