          may agree. If prior notification to or approval of the Federal Reserve
          Board or any other regulatory authority is required as a condition
          precedent to such purchase, then (A) Holder shall promptly file and
          process the required notice or application for approval; (B) Issuer
          shall cooperate with Holder in the filing of the required notice or
          application for approval and the obtaining of any such approval; and

          Holder to submit such filing to, and, if necessary, to obtain such
          approval from, the Federal Reserve Board or other applicable
          regulatory authority; provided, however, that the notice of Option
          exercise and such governmental filing must be made, and the Notice
          Date must be, no later than the date on which the Option would
          otherwise terminate. Any exercise of the Option shall be deemed to
          have occurred on the Notice Date.

     4.  Payment and Delivery of Certificates.
         ------------------------------------

               (a)  On each Closing Date, Holder shall (i) pay to Issuer, in
          immediately available funds by wire transfer to a bank account
          designated by Issuer, an amount equal to the Purchase Price multiplied
          by the number of Option Shares to be purchased on such Closing Date
          and (ii) present and surrender this Agreement to the Issuer at the
          address of the Issuer specified in Section 12(g) hereof.

               (b)  At each Closing, simultaneously with the delivery of

          certificate or certificates representing the Option Shares to be
          purchased at such Closing, which Option Shares shall be free and clear
          of all liens, claims, charges and encumbrances of any kind whatsoever,
          and (B) if the Option is exercised in part only, an executed new
          agreement with the same terms as this Agreement evidencing the right
          to purchase the balance of the shares of Issuer Common Stock
          purchasable hereunder; and (ii) Holder shall deliver to Issuer a
          letter agreeing that Holder shall not offer to sell or otherwise
          dispose of such Option Shares in violation of the provisions of this
          Agreement or applicable state and federal securities laws.

               (c)  Certificates for the Option Shares delivered at each Closing
          shall be endorsed with a restrictive legend which shall read
          substantially as follows:

    THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT") OR QUALIFIED OR
    REGISTERED UNDER THE SECURITIES LAWS OF ANY STATE. THEY MAY


    NOT BE SOLD OR TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
    STATEMENT UNDER THE ACT AND UNTIL THEY HAVE BEEN QUALIFIED OR REGISTERED
    UNDER APPLICABLE STATE SECURITIES LAWS, UNLESS THE ISSUER RECEIVES AN
    OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES, REASONABLY
    SATISFACTORY TO THE ISSUER, STATING THAT SUCH SALE OR TRANSFER IS EXEMPT
    FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF THE ACT AND

of substitute certificate(s) without such legend if Holder shall have delivered
to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel
in form and substance reasonably satisfactory to Issuer and its counsel, to the
effect that such legend is not required for purposes of the Securities Act or
applicable state securities laws.

securities laws.

     7.  Adjustment Upon Changes in Capitalization, etc.
         -----------------------------------------------

               (a)  In the event of any change in Issuer Common Stock by reason
            of a stock dividend, stock split, split-up, recapitalization,
            combination, exchange of shares or similar transaction, the type and
            number of shares or


            securities subject to the Option, and the Purchase Price therefor,
            shall be adjusted appropriately, and proper provision shall be made
            in the documentation pertaining to such transaction so that Holder
            shall receive, upon exercise of the Option, the number and class of
            shares or other securities or property that Holder would have
            received in respect of Issuer Common Stock if the Option had been
            exercised immediately prior to such event, or the record date
            therefor, as applicable. If any additional shares of Issuer Common
            Stock are issued after the date of this Agreement (whether upon
            exercise of stock options or otherwise but excluding any issuance
            pursuant to an event described in the first sentence of this Section
            7(a)), the number of shares of Issuer Common Stock subject to the
            Option shall be adjusted so that, after such issuance, such number
            of shares, together with any shares of Issuer Common Stock
            previously issued pursuant hereto, equals 19.9% of the number of
            shares of Issuer Common Stock then issued and outstanding, without
            giving effect to any shares subject to or issued pursuant to the
            Option (with any fractional share being rounded up to the next full
            share). Issuer agrees that in no event shall the number of shares of
            Issuer Common Stock issued after the date of this Agreement pursuant
            to the preceding sentence, together with the number of shares of
            Issuer Common Stock subject to the Option, adjusted as aforesaid,
            exceed the number of available authorized but unissued and
            unreserved shares of Issuer Common Stock. Nothing contained in this
            Section 7(a) or elsewhere in this Agreement shall be deemed to
            authorize Issuer to issue shares in breach of any provision of the
            Reorganization Agreement.

               (b)  In the event that Issuer shall, prior to the occurrence of
            an event set forth in Section 3(a) terminating the Holder's right to
            exercise the Option, enter into an agreement (i) to consolidate with
            or merge into any person, other than Grantee or one of its
            subsidiaries, and shall not be the continuing or surviving
            corporation of such consolidation or merger, (ii) to permit any
            person, other than Grantee or one of its subsidiaries, to merge into
            Issuer and Issuer shall be the continuing or surviving corporation,
            but, in connection with such merger, the then outstanding shares of
            Issuer Common Stock shall be changed into or exchanged for stock or
            other securities of Issuer or any other person or cash or any other
            property or the outstanding shares of Issuer Common Stock
            immediately prior to such merger shall after such merger represent
            less than 50% of the outstanding shares and share equivalents of the
            merged company, or (iii) to sell or otherwise transfer all or
            substantially all of its consolidated assets or deposit liabilities
            to any person other than Grantee or one of its subsidiaries, then,
            and in each such case, the agreement governing such transaction
            shall make proper provisions so that the Option shall, upon the
            consummation of any such transaction and upon the terms and
            conditions set forth herein, be converted into, or exchanged for, an
            option (the "Substitute Option"), at the, election of Grantee, of
            either (A) the Acquiring Corporation (as defined below), (B) any
            person that controls the Acquiring Corporation, (such person being
            referred to as the "Substitute Option Issuer"), or (C) in the case
            of a merger described in clause (ii), Issuer.


               (c)  The Substitute Option shall have the same terms as the
            Option, provided that if the terms of the Substitute Option cannot,
            for legal reasons, be the same as the Option, such terms shall be as
            similar as possible and in no event less advantageous to Grantee.
            The Substitute Option Issuer shall also enter into an agreement with
            the then holder or holders of the Substitute Option in substantially
            the same form as this Agreement (after giving effect for such
            purposes to the provisions of this Agreement), which shall be
            applicable to the Substitute Option.

               (d)  The Substitute Option shall be exercisable for such number
            of shares of the Substitute Common Stock (as is hereinafter defined)
            as is equal to the Assigned Value (as is hereinafter defined)
            multiplied by the number of shares of the Issuer Common Stock for
            which the Option was theretofore exercisable, divided by the Average
            Price (as is hereinafter defined). The exercise price of the
            Substitute Option per share of the Substitute Common Stock (the
            "Substitute Purchase Price") shall then be equal to the Purchase
            Price multiplied by a fraction in which the numerator is the number
            of shares of the Issuer Common Stock for which the Option was
            theretofore exercisable and the denominator is the number of shares
            of the Substitute Common Stock for which the Substitute Option is
            exercisable.

               (e)  As used herein, the following terms have the meanings
            indicated:

                    (i)    "Acquiring Corporation" shall mean (A) the continuing
            or surviving corporation of a consolidation or merger with Issuer
            (if other than Issuer), (B) Issuer in a merger in which Issuer is
            the continuing or surviving person, and (C) the transferee of all or
            any substantial part of the Issuer's assets (or the assets of its
            subsidiaries).

                    (ii)   "Substitute Common Stock" shall mean the common stock
            issued by the Substitute Option Issuer upon exercise of the
            Substitute Option.

                    (iii)  "Assigned Value" shall mean the highest of (A) the
            price per share of the Issuer Common Stock at which a Tender Offer
            or Exchange Offer therefor has been made by any person (other than
            Grantee or a subsidiary of Grantee), (B) the price per share of the
            Issuer Common Stock to be paid by any person (other than Grantee or
            a subsidiary of Grantee) pursuant to an agreement with Issuer, and
            (C) the highest closing price per share of Issuer Common Stock as
            quoted on The Nasdaq Stock Market (or if Common Stock is not quoted
            on The Nasdaq Stock Market, the highest bid price per share on any
            day as quoted on the principal trading market or securities exchange
            on which such shares are traded as reported by a recognized source
            chosen by


            Grantee and reasonably acceptable to Issuer) within the six-month
            period immediately preceding the agreement governing the transaction
            described in Section 7(b) which gave rise to the Substitute Option;
            provided, however, that in the event of a sale of less than all of
            Issuer's consolidated assets or deposit liabilities, the Assigned
            Value shall be the sum of the price paid in such sale for such
            assets or deposit liabilities and the current market value of the
            remaining consolidated net assets of Issuer as determined by a
            nationally recognized investment banking firm selected by the Holder
            (or by a majority in interest of the Holders if there shall be more
            than one Holder (a "Holder Majority")) and reasonably acceptable to
            Issuer, divided by the number of shares of the Issuer Common Stock
            outstanding at the time of such sale. In the event that an exchange
            offer is made for the Issuer Common Stock or an agreement is entered
            into for a merger or consolidation involving consideration other
            than cash, the value of the securities or other property issuable or
            deliverable in exchange for the Issuer Common Stock shall be
            determined by a nationally recognized investment banking firm
            selected by Holder (or a Holder Majority) and reasonably acceptable
            to Issuer.

                    (iv)   "Average Price" shall mean the average closing price
            of the Substitute Common Stock for the one year immediately
            preceding the effective date of the consolidation, merger or sale in
            question, but in no event higher than the closing price of the
            shares of the Substitute Common Stock on the day preceding such
            consolidation, merger or sale; provided that if Issuer is the issuer
            of the Substitute Option, the Average Price shall be computed with
            respect to a share of common stock issued by Issuer, the person
            merging into Issuer or by any company which controls or is
            controlled by such merging person, as Holder may elect.

               (f)  In no event, pursuant to any of the foregoing paragraphs,
          shall the Substitute Option be exercisable for more than 19.9% of the
          aggregate of the shares of the Substitute Common Stock outstanding
          prior to exercise of the Substitute Option (with any fractional share
          being rounded up to the next full share). In the event that the
          Substitute Option would be exercisable for more than 19.9% of the
          aggregate of the shares of the Substitute Common Stock but for this
          clause (f), the Substitute Option Issuer shall make a cash payment to
          Grantee equal to the excess of (i) the value of the Substitute Option
          without giving effect to the limitation in this clause (f) over (ii)
          the value of the Substitute Option after giving effect to the
          limitation in this clause (f). The difference in value shall be
          determined by a nationally recognized investment banking firm selected
          by Grantee and reasonably acceptable to the Substitute Option Issuer,
          whose determination shall be conclusive and binding on the parties.


               (g)  Issuer shall not enter into any transaction described in
          subsection (b) of this Section 7 unless the Acquiring Corporation and
          any person that controls the Acquiring Corporation assume in writing
          all the obligations of Issuer hereunder and take all other actions
          that may be necessary so that the provisions of this Section 7 are
          given full force and effect (including, without limitation, any action
          that may be necessary so that the shares of Substitute Common Stock
          are in no way distinguishable from or have lesser economic value than
          other shares of common stock issued by the Substitute Option Issuer).

               (h)  At the written request of Holder delivered to the Substitute
          Option Issuer prior to the occurrence of an event set forth in Section
          3(a) above terminating the Substitute Option, the Substitute Option
          Issuer shall repurchase from Holder (i) the Substitute Option and/or
          (ii) all Substitute Common Stock theretofore purchased by Holder
          pursuant hereto with respect to which Holder then has beneficial
          ownership. The date on which Holder exercises its rights under this
          Section 7(h) is referred to as the "Substitute Option Request Date."
          Such repurchase shall be at an aggregate price (the "Substitute Option
          Repurchase Consideration") equal to the sum of (A) the excess, if any,
          of (1) the Highest Closing Price (as defined below) for each share of
          Substitute Common Stock over (2) the Substitute Purchase Price per
          share of Substitute Common Stock, multiplied by the number of shares
          of Substitute Common Stock for which the Substitute Option may then be
          exercised and as to which Holder has exercised its repurchase right
          hereunder, plus (B) the Highest Closing Price for each share of
          Substitute Common Stock, multiplied by the number of shares of
          Substitute Common Stock previously acquired by Holder upon exercise of
          the Option or Substitute Option and as to which Holder has exercised
          its repurchase right hereunder. The term "Highest Closing Price" shall
          mean the highest closing price per share of Substitute Common Stock on
          the Nasdaq National Market (or, if Substitute Common Stock is not
          quoted on The Nasdaq Stock Market, the highest bid price per share on
          any day as quoted on the principal trading market or securities
          exchange on which such shares are traded as reported by a recognized
          source chosen by Grantee and reasonably acceptable to Issuer) or, if
          such shares are not traded in a trading market or listed on an
          exchange, as quoted by the brokerage firms acting as market makers for
          the Substitute Common Stock prior to the trading or listing of the
          Substitute Common Stock on any national securities exchange and
          thereafter as reported by the principal trading market or securities
          exchange on which such shares are traded, during the 60 business days
          preceding the Substitute Option Request Date.

               (i)  The provisions of Sections 8(b), 8(c), 11 and 12 shall
          apply, with appropriate adjustments, to any securities for which the
          Option becomes exercisable pursuant to this Section 7 and as
          applicable, references in such sections to "Issuer", "Option",
          "Purchase Price", "Issuer Common Stock", "Repurchase Consideration",
          and "Request Date" shall be deemed to be references to "Substitute
          Option Issuer", "Substitute Option", "Substitute


          Purchase Price", "Substitute Common Stock", "Substitute Option
          Repurchase Consideration", and "Substitute Option Request Date",
          respectively.

     8.  Repurchase at the Option of Grantee.
         -----------------------------------

               (a)  At any time after the first occurrence of a Repurchase Event
          (as defined in Section 8(e) below), at the written request of Holder
          delivered to Issuer prior to the occurrence of an event set forth in
          Section 3(a) above terminating the Option, Issuer shall repurchase
          from Holder (i) the Option and (ii) all Option Shares theretofore
          purchased by Holder pursuant hereto with respect to which Holder then
          has beneficial ownership. The date on which Holder exercises its
          rights under this Section 8 is referred to as the "Request Date." Such
          repurchase shall be at an aggregate price (the "Repurchase
          Consideration") equal to the sum of:

                    (i)    the aggregate Purchase Price paid by Holder for any
            Option Shares acquired pursuant to the Option with respect to which
            Holder then has beneficial ownership;

                    (ii)   the excess, if any, of (A) the Applicable Price (as
            defined below) for each Option Share over (B) the Purchase Price per
            Option Share (subject to adjustment pursuant to Section 7(a)),
            multiplied by the number of Option Shares with respect to which the
            Option has not been exercised; and

                    (iii)  the excess, if any, of the Applicable Price over the
            Purchase Price (subject to adjustment pursuant to Section 7(a)) paid
            (or, in the case of Option Shares with respect to which the Option
            has been exercised but the Closing Date has not occurred, payable)
            by Holder for each Option Share with respect to which the Option has
            been exercised and with respect to which Holder then has beneficial
            ownership, multiplied by the number of such shares.

               (b)  If Holder exercises its rights under this Section 8, Issuer
          shall, within ten (10) business days after the Request Date, pay the
          Repurchase Consideration to Holder in immediately available funds, and
          Holder shall surrender to Issuer the Option and the certificates
          evidencing the Option Shares purchased thereunder with respect to
          which Holder then has beneficial ownership and has designated to be
          repurchased, and Holder shall warrant that it has sole record and
          beneficial ownership of such shares and that the same are then free
          and clear of all liens, claims, charges and encumbrances of any kind
          whatsoever.

               (c)  Notwithstanding the provisions hereof to the contrary, to
          the extent that Issuer is prohibited under applicable law, regulation
          or


          administrative policy from repurchasing all or any portion of the
          Option or Option Shares, then (i) Issuer shall promptly give notice of
          such fact to Holder; (ii) Issuer shall, from time to time subject to
          the last sentence of this Section 8(c), deliver to Holder that portion
          of the Repurchase Consideration that it is not then so prohibited from
          paying; (iii) at Holder's request, Issuer shall promptly file any
          required notice or application for approval and expeditiously process
          the same. After Holder's receipt of such notice from Issuer, Issuer
          shall not be in breach of its repurchase obligation hereunder to the
          extent it is or remains, despite reasonable efforts to obtain any
          required approvals, legally prohibited from repurchasing the Option or
          Option Shares. Holder shall have the right (A) to revoke its request
          for repurchase with respect to the portion of the Option or Option
          Shares that Issuer is prohibited from repurchasing, (B) to require
          Issuer to deliver to Holder the Option and/or Option Shares Issuer is
          prohibited from repurchasing, and (C) to exercise the Option as to the
          number of Option Shares for which the Option was exercisable at the
          Request Date less the number of such Option Shares in respect of which
          the Repurchase Consideration has been lawfully paid. Notwithstanding
          anything herein to the contrary, Issuer shall not be obligated to
          repurchase all or any part of the Option or Option Shares pursuant to
          more than one written request from Holder, except that Issuer shall be
          obligated to repurchase, pursuant to more than one written request,
          any Option or Option Shares in the event that Holder (1) has revoked
          its request for repurchase in accordance with the provisions of this
          Section 8 prior to the occurrence of an event set forth in Section
          3(a) terminating the Holder's right to exercise the Option and (2) has
          delivered, prior to such event, a new written notice requesting a
          repurchase. If an event set forth in Section 3(a) terminating the
          Holder's right to exercise the Option occurs prior to, or is scheduled
          to occur within, 60 days after the date of the notice by Issuer
          described in clause 8(c)(i) above, then, notwithstanding the
          occurrence of such terminating event, Holder shall have the right to
          receive the Repurchase Consideration to the extent Issuer is or
          becomes, within a 60 day period from the date of such notice by
          Issuer, legally permitted to repurchase. Except as set forth in the
          preceding sentence, Holder's repurchase rights under this Agreement
          shall terminate concurrently with the termination of Holder's right to
          exercise the Option, pursuant to Section 3(a).

               (d)  For purposes of this Agreement, the "Applicable Price" means
          the highest of (i) the highest price per share of Issuer Common Stock
          paid for any such share by the person or groups described in Section
          8(e)(i), (ii) the price per share of Issuer Common Stock received by
          holders of Issuer Common Stock in connection with any merger or other
          business combination transaction described in Section 7(b)(i),
          7(b)(ii) or 7(b)(iii), or (iii) the highest bid price per share of
          Issuer Common Stock on The Nasdaq Stock Market or other principal
          trading market or securities exchange on which such shares are traded
          as reported by a recognized source selected by Holder during the 60
          business days preceding the Request Date; provided, however, that in
          the event of a sale of less than all of Issuer's assets, the
          Applicable Price shall be


          the sum of the price paid in such sale for such assets or deposit
          liabilities and the current market value of the remaining consolidated
          net assets of Issuer as determined by a nationally recognized
          investment banking firm selected by Holder (or the Holder Majority)
          and reasonably acceptable to Issuer, divided by the number of shares
          of the Issuer Common Stock outstanding at the time of such sale. If
          the consideration to be offered, paid or received pursuant to either
          of the foregoing clauses (i) or (ii) shall be other than in cash, the
          value of such consideration shall be determined in good faith by an
          independent nationally recognized investment banking firm selected by
          Holder (or the Holder Majority) and reasonably acceptable to Issuer,
          which determination shall be conclusive for all purposes of this
          Agreement.

               (e)  As used herein, a "Repurchase Event" shall occur if (i) any
          person (other than Grantee or any subsidiary of Grantee) shall have
          acquired beneficial ownership of (as such term is defined in Rule 13d-
          3 promulgated under the Exchange Act) or the right to acquire
          beneficial ownership of, or any "group" (as such term is defined under
          the Exchange Act and the rules and regulations promulgated thereunder)
          shall have been formed which beneficially owns, or has the right to
          acquire beneficial ownership of, fifty percent (50%) or more of the
          then outstanding shares of Issuer Common Stock or (ii) any of the
          transactions described in Section 7(b)(i), 7(b)(ii) or 7(b)(iii) shall
          be consummated.

     9.  Registration Rights.
         --------------------

               (a) Demand Registration Rights. Issuer shall, subject to the
                   --------------------------
conditions of Section 9(c) below, if requested by any Holder, including Grantee
and any permitted transferee ("Selling Shareholder"), after exercise of the
Option and prior to an Expiration Date, expeditiously prepare and file, a
registration statement under the Securities Act if such registration is
necessary in order to permit the sale or other disposition of any or all shares
of Issuer Common Stock or other securities that have been acquired by or are
issuable to the Selling Shareholder upon exercise of the Option in accordance
with the intended method of sale or other disposition stated by the Selling
Shareholder in such request, including without limitation a "shelf" registration
statement under Rule 415 under the Securities Act or any successor provision,
and Issuer shall use its best efforts to qualify such shares or other securities
for sale under any applicable state securities laws. Issuer shall not be
obligated to effect more than one (1) registration pursuant to this Section
9(a).

               (b) Additional Registration Rights.  If Issuer at any time after
                   ------------------------------
the exercise of the Option proposes to register any shares of Issuer Common
Stock under the Securities Act in connection with an underwritten public
offering of such Issuer Common Stock, Issuer will promptly give written notice
to the Holders of its intention to do so and, upon the written request of any
Holder given within 30 days after receipt of any such notice (which request
shall specify the number of shares of Issuer Common Stock intended to be
included in such underwritten public offering by the Holder), Issuer will cause
all such shares for which a Holder requests participation in such registration,
to be so registered and included in such underwritten public offering; provided,
however, that Issuer may elect to not cause all of such


shares to be so registered (i) if the managing underwriter imposes a limitation
on the number of shares of Issuer Common Stock that may be included in the
registration because, in such underwriter's judgment, such limitation would be
necessary to effect an orderly public distribution, then Issuer will be
obligated to include only such limited portion, if any, of the Issuer Common
Stock with respect to which the Holders have requested inclusion hereunder, or
(ii) in the case of a registration solely to implement an employee benefit plan
or a registration filed on Form S-4 of the Securities Act or any successor form,
in which case Issuer shall not be required to include any of Holder's shares in
the registration; provided, further, however, that an election pursuant to (i)
may be only made one time. If some but not all the shares of Issuer Common
Stock, with respect to which Issuer shall have received requests for
registration pursuant to this Section 9(b), shall be excluded from such
registration, Issuer shall make appropriate allocation of shares to be
registered among the Holders desiring to register their shares pro rata in the
proportion that the number of shares requested to be registered by each such
Holder bears to the total number of shares requested to be registered by all
such Holders then desiring to have Issuer Common Stock registered for sale.
Issuer shall not be obligated to effect more than one (1) registration pursuant
to this Section 9(b).

               (c) Conditions to Required Registration. Issuer shall use all
reasonable efforts to cause each registration statement referred to in Section
9(a) above to become effective and to obtain all consents or waivers of other
parties which are required therefor and to keep such registration statement
effective; provided, however, that Issuer may delay any registration of Option
Shares required pursuant to Section 9(a) above for a period not exceeding 90
days if Issuer determines, in the good faith exercise of its reasonable business
judgment, that such registration and offering could adversely effect or
interfere with bona fide financing plans of Issuer or would require disclosure
of information, the premature disclosure of which could adversely affect Issuer
or any transaction under active consideration by Issuer. Notwithstanding
anything to the contrary stated herein, Issuer shall not be required to register
Option Shares under the Securities Act pursuant to Section 9(a) above:

                    (i)    on more than one occasion during any calendar year;

                    (ii)   within 90 days after the effective date of a
registration referred to in Section 9(b) above pursuant to which the Holders
concerned were afforded the opportunity to register or qualify such shares under
the Securities Act and such shares were registered or qualified as requested,
and

                    (iii)  unless a request therefor is made to Issuer by
Holders that hold at least 25% or more of the aggregate number of Option Shares
(including shares of Issuer Common Stock issuable upon exercise of the Option)
then outstanding.

In addition to the foregoing, Issuer shall not be required to maintain the
effectiveness of any registration statement after the expiration of nine months
from the effective date of such registration statement.   Issuer shall use all
reasonable efforts to make any filings, and take all steps, under all applicable
state securities laws to the extent necessary to permit the sale or other
disposition of the Option Shares so registered in accordance with the intended
method of distribution for such shares; provided, however, that Issuer shall not
be required to consent to the


general jurisdiction or qualify to do business in any state where it is not
otherwise required to so consent to such jurisdiction or to so qualify to do
business.

               (d) Expenses.  Except where applicable state law prohibits such
                   --------
payments, Issuer will pay the costs of such registration or qualification
expenses, including without limitation registration fees, qualification fees,
blue sky fees and expenses, Issuer's legal expenses, costs of special audits or
"cold comfort" letters, expenses of underwriters, excluding discounts and
commissions, and the reasonable fees and expenses of any necessary special
experts in connection with each registration pursuant to Section 9(a) or (b)
above (including the related offerings and sales by holders of Option Shares)
and all other qualifications, notifications, or exemptions pursuant to Section
9(a) or 9(b) above.

               (e) Indemnification.  In connection with any registration under
                   ---------------
Section 9(a) or 9(b) above, Issuer hereby indemnifies the Selling Shareholders,
and each underwriter thereof, including each person, if any, who controls such
holder or underwriter within the meaning of Section 15 of the Securities Act,
against all expenses, losses, claims, damages and liabilities caused by any
untrue, or alleged untrue, statement of a material fact contained in any
registration statement or prospectus or notification or offering circular
(including any amendments or supplements thereto) or any preliminary prospectus,
or caused by 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 such expenses, losses, claims, damages or
liabilities of such indemnified party are caused by any untrue statement or
alleged untrue statement that was included by Issuer in any such registration
statement or prospectus or notification or offering circular (including any
amendments or supplements thereto) in reliance upon, and in conformity with,
information furnished in writing to Issuer by such indemnified party or any
underwriter expressly for use therein, and Issuer and each officer, director and
controlling person of Issuer shall be indemnified by such Selling Shareholders,
or by such underwriter, as the case may be, for all such expenses, losses,
claims, damages and liabilities caused by any untrue, or alleged untrue,
statement, that was included by Issuer in any such registration statement or
prospectus or notification or offering circular (including any amendments or
supplements thereto) in reliance upon, and in conformity with, information
furnished in writing to Issuer by such holder or such underwriter, as the case
may be, expressly for such use.

     Promptly upon receipt by a party indemnified under this Section 9(e) of
notice of the commencement of any action against such indemnified party in
respect of which indemnity or reimbursement may be sought against any
indemnifying party under this Section 9(e), such indemnified party shall notify
the indemnifying party in writing of the commencement of such action, but the
failure so to notify the indemnifying party shall not relieve it of any
liability which it may otherwise have to any indemnified party under this
Section 9(e). In case notice of commencement of any such action shall be given
to the indemnifying party as above provided, the indemnifying party shall be
entitled to participate in and, to the extent it may wish, jointly with any
other indemnifying party similarly notified, to assume the defense of such
action at its own expense, with counsel chosen by it and satisfactory to such
indemnified party. The indemnified party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees
and expenses of such counsel (other than reasonable costs of investigation)
shall be paid by the indemnified party unless (i) the


indemnifying party either agrees to pay the same, (ii) the indemnifying party
fails to assume the defense of such action with counsel reasonably satisfactory
to the indemnified party, or (iii) the indemnified party has been advised by
counsel that one or more legal defenses may be available to the indemnified
party that may be contrary to the interest of the indemnifying party. No
indemnifying party shall be liable for any settlement entered into without its
consent, which consent may not be unreasonably withheld.

     If the indemnification provided for in this Section 9(e) is unavailable to
a party otherwise entitled to be indemnified in respect of any expenses, losses,
claims, damages or liabilities referred to herein, then the indemnifying party,
in lieu of indemnifying such party otherwise entitled to be indemnified, shall
contribute to the amount paid or payable by such party to be indemnified as a
result of such expenses, losses, claims, damages or liabilities in such
proportion as is appropriate to reflect the relative benefits received by
Issuer, the Selling Shareholders and the underwriters from the offering of the
securities and also the relative fault of Issuer, the Selling Shareholders and
the underwriters in connection with the statements or omissions which resulted
in such expenses, losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The amount paid or payable by a party as a
result of the expenses, losses, claims, damages and liabilities referred to
above shall be deemed to include any legal or other fees or expenses reasonably
incurred by such party in connection with investigating or defending any action
or claim, provided, however, that in no case shall any Selling Shareholder be
responsible, in the aggregate, for any amount in excess of the net offering
proceeds attributable to its Option Shares included in the offering. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. Any obligation by any holder to
indemnify shall be several and not joint with other holders.

     In connection with any registration pursuant to Section 9(a) or 9(b) above,
Issuer and each Selling Shareholder (other than Grantee) shall enter into an
agreement containing the indemnification provisions of this Section 9(e).

               (f) Miscellaneous Reporting.  Issuer shall comply with all
                   -----------------------
reporting requirements and will do all such other things as may be necessary to
permit the expeditious sale at any time of any Option Shares by the Selling
Shareholders thereof in accordance with and to the extent permitted by any rule
or regulation promulgated by the SEC from time to time. Issuer shall at its
expense provide the Selling Shareholders with any information necessary in
connection with the completion and filing of any reports or forms required to be
filed by them under the Securities Act or the Exchange Act, or required pursuant
to any state securities laws or the rules of any stock exchange.

     10.  Listing.  If Issuer Common Stock or any other securities to be
          -------
acquired upon exercise of the Option are not then authorized for quotation on
The Nasdaq Stock Market or any securities exchange, Issuer, upon the request of
Holder, will promptly file an application to authorize for quotation the shares
of Issuer Common Stock or other securities to be acquired upon exercise of the
Option on The Nasdaq Stock Market and will use its commercially reasonable
efforts to obtain approval of such listing as soon as practicable.


     11.  Division of Option.  This Agreement (and the Option granted hereby)
          ------------------
are exchangeable, without expense, at the option of Holder, upon presentation
and surrender of this Agreement at the principal office of Issuer for other
agreements providing for other options of different denominations entitling the
holder thereof to purchase in the aggregate the same number of shares of Issuer
Common Stock purchasable hereunder. The terms "other agreements" and "other
options" as used in the preceding sentence mean any other agreements and related
options for which this Agreement (and the Option granted hereby) may be
exchanged. Upon receipt by Issuer of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Agreement, and (in the case
of loss, theft or destruction) of reasonably satisfactory indemnification, and
upon surrender and cancellation of this Agreement, if mutilated, Issuer will
execute and deliver a new Agreement of like tenor and date. Any such new
Agreement executed and delivered shall constitute an additional contractual
obligation on the part of Issuer, whether or not the Agreement so lost, stolen,
destroyed or mutilated shall at any time be enforceable by anyone.

     12.  Limitation on Total Profit and Notional Total Profit.
          -----------------------------------------------------

               (a) Notwithstanding anything to the contrary contained herein, in
no event shall Grantee's Total Profit (as defined below in Section 12(c) hereof)
exceed $5,500,000 and, if it otherwise would exceed such amount, Grantee, at its
sole election, shall either (i) reduce the number of shares of Issuer common
stock subject to the Option, (ii) pay cash to Issuer, or (iii) any combination
thereof, so that Grantee's actually realized Total Profit shall not exceed
$5,500,000 after taking into account the foregoing actions.

               (b) Notwithstanding anything to the contrary contained herein,
the Option may not be exercised for a number of shares as would, as of the date
of exercise, result in a Notional Total Profit (as defined below in Section
12(d) hereof) of more than $5,500,000; provided, that nothing in this sentence
shall restrict any exercise of the Option permitted hereby on any subsequent
date on which the Notional Total Profit would be less than $5,500,000.

               (c) As used herein, the term "Total Profit" shall mean the
aggregate amount (before taxes) of the following: (i) the amount received by
Grantee pursuant to Issuer's repurchase of the Option (or any portion thereof)
pursuant to Section 8 hereof, (ii) (x) the amount received by Grantee or any
affiliate of Grantee pursuant to Issuer's repurchase of Option Shares pursuant
to Section 8 hereof, less (y) Grantee's or any affiliate of Grantee's purchase
price for such Option Shares, (iii) (x) the net cash amounts received by Grantee
or any affiliate of Grantee pursuant to the sale of Option Shares (or any other
securities into which such Option Shares shall be converted or exchanged) to any
unaffiliated party, less (y) Grantee's or any affiliate of Grantee's purchase
price of such Option Shares, and (iv) any equivalent amounts with respect to the
Substitute Option.

               (d) As used herein, the term "Notional Total Profit" with respect
to any number of shares as to which Grantee or any affiliate of Grantee may
propose to exercise the Option shall be the Total Profit determined as of the
date of such proposed exercise assuming that the Option were exercised on such
date for such number of shares and assuming that such shares, together with all
other Option Shares held by Grantee or any affiliate of Grantee as of


such date, were sold for cash at the closing market price for the Issuer Common
Stock as of the close of business on the preceding trading day (less customary
brokerage commissions).

               (e) Grantee agrees, promptly following any exercise of all or any
portion of the Option, and subject to its rights under Section 8 hereof, to use
and cause any wholly owned Subsidiary of Grantee to use commercially reasonable
efforts promptly to maximize the value of Option Shares purchased taking into
account market conditions, the number of Option Shares, the potential negative
impact of substantial sales on the market price for Issuer Common stock, and the
availability of an effective registration statement to permit public sale of
Option Shares.

     13.  Miscellaneous.
          -------------

                    (a)  Expenses.  Except as otherwise provided in Section 9,
                         --------
            each of the parties hereto and any Holder shall bear and pay all
            costs and expenses incurred by it or on its behalf in connection
            with the transactions contemplated hereunder, including, without
            limitation, fees and expenses of its own financial consultants,
            investment bankers, accountants and counsel.

                    (b)  Waiver and Amendment.  Any provision of this Agreement
                         --------------------
            may be waived at any time by the party that is entitled to the
            benefits of such provision. This Agreement may not be modified,
            amended, altered or supplemented except upon the execution and
            delivery of a written agreement executed by the parties hereto.

                    (c)  Entire Agreement; No Third-Party Beneficiary.  This
                         --------------------------------------------
            Agreement, together with the Reorganization Agreement and the other
            documents and instruments referred to herein and therein (i)
            constitutes the entire agreement and supersedes all prior agreements
            and understandings, both written and oral, between the parties with
            respect to the subject matter hereof and (ii) is not intended to
            confer upon any person other than the parties hereto, and their
            respective successors and assigns, any rights or remedies hereunder,
            except as expressly provided in this Agreement.

                    (d)  Severability.  If any term, provision, covenant or
                         ------------
            restriction of this Agreement is held by a court or a federal or
            state regulatory authority of competent jurisdiction to be invalid,
            void or unenforceable, such invalid, void or unenforceable term,
            provision, covenant or restriction shall, if it is so susceptible,
            be deemed modified to the minimum extent necessary to render the
            same valid and enforceable and, in all events, the remainder of the
            terms, provisions, covenants and restrictions of this Agreement
            shall remain in full force and effect and shall in no way be
            affected, impaired or invalidated. Without limiting the foregoing,
            if for any reason such court or regulatory authority determines that
            Holder may not legally acquire, or Issuer may not legally
            repurchase, the full number of shares of Issuer Common Stock as
            provided in Sections 3 and 8 (as adjusted pursuant to Section 7), it
            is the express intention of Issuer to allow Holder to acquire or to
            require Issuer to


            repurchase the maximum number of shares as may be legally
            permissible without any amendment or modification hereof.

                    (e)  Governing Law.  This Agreement shall be governed and
                         -------------
            construed in accordance with the laws of the State of California
            without regard to any applicable conflicts of law rules.

                    (f)  Descriptive Headings.  The descriptive headings
                         --------------------
            contained herein are for convenience of reference only and shall not
            affect in any way the meaning or interpretation of this Agreement.

                    (g)  Notices.  All notices, requests, claims, demands and
                         -------

            given) by personal delivery, by telecopy (provided that copy is

            may be executed in two counterparts, each of which shall be
            considered one and the same agreement and shall become effective
            when both counterparts have been signed, it being understood that
            both parties need not sign the same counterpart.

                    (i)  Assignment.  Neither this Agreement nor any of the
                         ----------
            rights, interests or obligations hereunder or under the Option shall
            be assigned by any of the parties hereto without the prior written
            consent of the other party, except that Grantee may assign this
            Agreement to a wholly-owned subsidiary of Grantee and at any time

            entitling the holders thereof to purchase in the aggregate the same
            number of shares of Common Stock as may be purchasable hereunder.
