2.      DEMAND REGISTRATION

(a)     REQUEST FOR REGISTRATION. At any time after the earlier of (i) the one
        (1) year anniversary of date hereof or (ii) such time as the closing bid
        price for the Common Stock equals at least five (5) times the closing
        bid price of the Common Stock on the date hereof, a Holder may make a
        written request to the Company (a "DEMAND REQUEST"), for the
        registration under the Securities Act of all or part of such Holder's
        Registrable Shares (a "DEMAND REGISTRATION") so as to permit a public
        offering and sale of such Registrable Shares for up to twelve (12)
        consecutive months in accordance with the manner specified in such
        notice; provided, however, that the Company shall not be obligated to
        register Registrable Securities pursuant to such request: (i) in any
        particular jurisdiction in which the Company would be required to
        qualify to do business or to execute a general consent to service of
        process in effecting such registration when it was not then so qualified
        and had not filed such a consent; (ii) if the Company determines upon
        advice of counsel to the Company that the filing of such a registration
        statement would require the disclosure of material non-public
        information about the Company, the disclosure of which could have a
        material adverse effect on the business or financial condition of the
        Company and provides written notice of such determination to the
        requesting Holders, in which event no such registration statement shall
        be filed until the earlier of the lapse of ninety (90) days from the
        date of delivery of such notice or the Company's determination that such
        information is no longer required to be disclosed, is not material or
        non-public or its disclosure would not have a material adverse effect on
        the business or financial condition of the Company; provided, however,
        that (A) the Company shall evaluate all relevant facts and circumstances
        no less often than once every thirty (30) days in order to determine
        whether such information is no longer required to be disclosed, is not
        material or non-public or its disclosure would not have a material
        adverse effect on the business or financial condition of the Company and
        shall promptly notify the requesting Holders of such determination; and
        (B) the Company may not exercise its right under this clause (ii) and
        clause (iii) below more than once in any 12-month period and the
        aggregate number of days of any such deferral shall not exceed 90; or
        (iii) if the Company is in the process of consummating an underwritten
        primary registration at the time that a Demand Request


                                      -2-
<PAGE>

        is made, and the managing underwriters advise the Company in writing
        that in their reasonable opinion based upon market conditions such
        Demand Registration would have a Material Adverse Effect on the
        Company's underwritten primary registration; provided, however, that (A)
        a copy of such written opinion shall be promptly provided to each
        Requesting Holder; (B) within twenty (20) days after receiving such
        written opinion, the Holders of a majority of the Registrable Shares
        held by the Requesting Holders and for which registration was previously
        requested may withdraw such request by giving notice to the Company and,
        if so withdrawn, the Demand Request shall be deemed not to have been
        made for all purposes of this Agreement; and (C) a deferral of the
        filing of a registration statement pursuant to this clause (iii) shall
        be lifted, and the requested registration statement shall be filed
        forthwith upon the effectiveness of the Company's underwritten primary
        registration. Notwithstanding anything to the contrary contained herein,
        no request may be made under this Section 2(a) within 180 days after the
        effective date of a registration statement filed by the Company covering
        a firm commitment underwritten public offering in which the Holders of
        Registrable Securities shall have been entitled to join pursuant to this
        Section 2 or Section 3 hereof and in which there shall have been
        effectively registered all shares of Registrable Securities as to which
        registration shall have been so requested. Such request shall specify
        the number of Registrable Shares proposed to be sold and the intended
        method of disposition thereof. Upon receipt of such request, the Company
        shall promptly (but in any event within ten (10) days after receipt)
        give written notice of such registration request to all Holders. Such
        Holders shall have the right, by giving written notice to the Company
        within ten (10) days after the receipt of notice from the Company, to
        elect to have included in such registration all or part of their
        Registrable Shares as such Holders may request in such notice of
        election. Each such request will also specify the number of Registrable
        Shares to be registered and the intended method of disposition thereof.
        The Company shall file the Demand Registration within (i) forty-five
        (45) days if the Company is eligible to use Form S-3 or any substitute
        form adopted by the Commission ("SHORT-FORM REGISTRATION") or (ii) sixty
        (60) days if the Company is not eligible to use such Short-Term
        Registration, after receiving a Demand Request (the "REQUIRED FILING
        DATE") and shall use its best efforts to cause the same to be declared
        effective by the Commission as promptly as practicable after such
        filing. Notwithstanding the foregoing, in no event shall the Company be
        required to effect more than two (2) Demand Registrations pursuant to
        this Section 2(a); provided, however, that if a Holder elects to include
        all or part of such Holder's Registrable Shares in a Demand
        Registration, such registration shall not be counted as one of the
        registrations permitted hereunder unless such Holder is permitted to
        include in the Demand Registration all of the Registrable Shares that it
        desires to sell due to the limitations contained in Section 2(d) hereof.

(b)     EFFECTIVE REGISTRATION AND EXPENSES. A registration will not count as a
        Demand Registration until it has become effective (unless all Holders
        making or joining such request pursuant to Section 2(a) above (the
        "REQUESTING HOLDERS") withdraw all their Registrable Shares, in which
        case such demand will count as a Demand Registration unless the
        Requesting Holders pay all expenses in connection with such withdrawn
        registration); provided that if, after it has become effective, an
        offering of Registrable Shares pursuant to a registration is interfered
        with by any stop order, injunction, or other


                                      -3-
<PAGE>

        order or requirement of the Commission or other governmental agency or
        court, such registration will be deemed not to have been effected.

(c)     SELECTION OF UNDERWRITERS. If the Holders of a majority of the
        Registrable Shares to be registered in a Demand Registration so elect,
        the offering of Registrable Shares pursuant to a Demand Registration
        shall be in the form of an underwritten public offering. The Requesting
        Holders who hold a majority of the Registrable Shares to be registered
        in the Demand Registration shall be entitled to select the investment
        banking firm or firms to manage the underwritten offering, subject to
        the approval of the Company (not to be unreasonably withheld).

(d)     PRIORITY ON DEMAND REGISTRATIONS. No securities to be sold for the
        account of any Person (including the Company and including any other
        holder of capital stock of the Company) other than Requesting Holders
        shall be included in a Demand Registration that is an underwritten
        public offering unless (i) the managing underwriter or underwriters
        shall advise the Company or the Requesting Holders in writing that the
        inclusion of such securities will not materially and adversely affect
        the price or success of the offering (a "MATERIAL ADVERSE EFFECT") and
        (ii) the Holders of not less than a majority of the Registrable Shares
        to be covered by such registration (calculated by using numbers of
        shares of Common Stock of the Company represented by such Registrable
        Shares on an as-if-converted basis) shall have consented in writing to
        the inclusion of such other securities. Furthermore, and subject to the
        immediately following sentence, in the event the managing underwriter or
        underwriters shall advise the Company or the Requesting Holders that
        even after exclusion of all securities of other Persons pursuant to the
        immediately preceding sentence, the amount of Registrable Shares
        proposed to be included in such Demand Registration by Requesting
        Holders is sufficiently large to cause a Material Adverse Effect, the
        Registrable Shares of Requesting Holders to be included in such Demand
        Registration shall be allocated pro rata among the Requesting Holders on
        the basis of the number of Registrable Shares requested to be included
        in such Demand Registration by each such Requesting Holder.

3.      PIGGYBACK REGISTRATION

(a)     RIGHT TO PIGGYBACK. If the Company proposes to file a registration
        statement under the Securities Act with respect to an equity security of
        the Company for its own account or for the account of any of its
        securityholders (other than pursuant to Section 2 and other than a
        registration statement on Form S-4 or S-8 (or any substitute forms
        adopted by the Commission)), then the Company shall give prompt written
        notice to the Holders of its intention to effect such a registration
        (which notice shall be given not less than thirty (30) days prior to the
        anticipated filing date of such registration statement) and such notice
        shall offer the Holders who are holders of Registrable Shares the
        opportunity to have any or all of their Registrable Shares included in
        such registration statement, subject to the limitations contained in
        Section 3(b) hereof. The Holders shall advise the Company in writing
        within twenty (20) days after the date of receipt of such notice from
        the Company of such Holder's desire to have their Registrable Shares
        registered under this Section 3. Subject to Section 3(b) below, the
        Company shall include in such registration statement all such
        Registrable Shares so requested to be included therein pursuant to the
        piggyback


                                      -4-
<PAGE>

        rights granted under this Section 3(a); provided, however, that the
        Company may at any time withdraw or cease proceeding with any such
        registration if it shall at the same time withdraw or cease proceeding
        with the registration of all other equity securities originally proposed
        to be registered without any obligation to the Holders of any
        Registrable Securities. The Company (or such other Holders, as the case
        may be,) shall be entitled to select the investment banking firm or
        firms to manage any underwritten offering contemplated by this Section
        3(a).

(b)     PRIORITY ON REGISTRATIONS. If any managing underwriter advises the
        Company in writing that including all the shares of Common Stock
        requested to be included in the registration by all Persons (including
        the Company) would have a Material Adverse Effect, subject to the
        immediately following sentence, the Company will be obligated to include
        in such registration only Common Shares in the following priority: (i)
        first, if the registration statement has been proposed to be filed by
        the Company for its own account, any Common Stock for sale by the
        Company, and (ii) second, (x) if the registration statement has been
        proposed to be filed by the Company for its own account, pro rata among
        the Holders of the Registrable Shares requesting to be included in the
        registration based on the number of Registrable Shares, on an
        as-if-converted basis, requested to be included in such registration by
        each such Holder, or (y) if the registration statement has been proposed
        to be filed at the request and for the account of any of the Company's
        securityholders, pro rata among such requesting securityholders and the
        Holders of the Registrable Shares requesting to be included in the
        registration based on the number of shares of Common Stock, on an
        as-if-converted basis, requested to be included in such registration by
        each such Holder and each such securityholder, and (iii) third, in the
        event that all Common Stock for sale by the Company and all Registrable
        Shares requested to be included in such registration statement by the
        Holders of Registrable Shares and, if applicable, all Common Stock for
        sale by the requesting securityholders have been included in such
        registration, any other Common Stock requested to be included pursuant
        to any other registration rights that may hereafter be and to the extent
        granted by the Company (pro rata on the basis of the total number of
        shares of Common Stock that each holder of such shares has requested to
        be registered).

4.      MISCELLANEOUS REGISTRATION RIGHTS PROVISIONS

(a)     HOLDBACK AGREEMENT. If the Company previously shall have received a
        request for registration pursuant to Section 2 hereof or any Holder
        shall have requested to have such Holder's Registrable Shares registered
        pursuant to Section 3 hereof, and if such previous registration shall
        not have been withdrawn or abandoned, the Company agrees (A) not to
        effect any public sale or distribution of its equity securities, or any
        securities convertible into or exchangeable or exercisable for such
        securities, during the seven days prior to and during the 180-day period
        beginning on the effective date of such previous registration, and (B)
        to use its best efforts to cause each officer and director of the
        Company or any of its subsidiaries and each other holder of 5% or more
        of its equity securities (or any securities convertible into or
        exchangeable for such securities), on a fully diluted basis purchased
        from the Company at any time (other than in a registered public
        offering), to agree not to effect any public sale or distribution
        (including sales pursuant to Rule 144) of any such securities during
        such period (except as part of such registration, if otherwise


                                      -5-
<PAGE>

        permitted), unless the Holders of a majority of the Registrable Shares
        to be registered in such registration agree. Additionally, each Holder
        of Registrable Securities agrees, if so required by the managing
        underwriter of the public offering, not to effect any public sale or
        distribution of securities of the Company of the same class as the
        securities included in such registration statement, during the seven (7)
        days prior to the date on which any underwritten registration pursuant
        to Section 2 or 3 has become effective and the ninety (90) days (or such
        longer period as shall have been agreed to by all of the holders of
        securities included in such registration statement other than the
        Holders of Registrable Securities) thereafter, except as part of such
        underwritten registration or to the extent that such Holder is
        prohibited by applicable law from agreeing to withhold Registrable
        Securities from sale or is acting in its capacity as a fiduciary or an
        investment adviser. The Company agrees not to effect any public sale or
        distribution of its equity securities or securities convertible into or
        exchangeable or exercisable for any of such securities during the seven
        (7) days prior to and the ninety (90) days after any underwritten
        registration pursuant to Section 2 or 3 has become effective, except as
        part of such underwritten registration.

(b)     REGISTRATION PROCEDURES. Whenever the Holders have requested that any
        Registrable Shares be registered pursuant to this Agreement, the Company
        will use its best efforts to effect the registration and the sale of
        such Registrable Shares in accordance with the intended method of
        disposition thereof, and pursuant thereto the Company will as
        expeditiously as possible:

        (i)    prepare and, subject to Section 2(e), file with the Commission a
               registration statement on any appropriate form under the
               Securities Act, with respect to such Registrable Shares and use
               its best efforts to cause such registration statement to become
               effective at the earliest possible time (provided that before
               filing a registration statement or prospectus or any amendments
               or supplements thereto, the Company will furnish to the counsel
               selected by the Holders of a majority of the Registrable Shares
               covered by such registration statement copies of all such
               documents proposed to be filed);

        (ii)   prepare and file with the Commission and notify each seller of
               such Registrable Shares immediately after the filing of such
               amendments, post-effective amendments, and supplements to such
               registration statement and the prospectus used in connection
               therewith as may be necessary to keep such registration statement
               effective for a period of not less than 180 days, in the case of
               a piggyback registration, or 360 days in the case of a Demand
               Registration (or such lesser periods as is necessary for the
               underwriters in an underwritten offering to sell unsold
               allotments) and comply with the provisions of the Securities Act
               with respect to the disposition of all securities covered by such
               registration statement during such period in accordance with the
               intended methods of disposition by the sellers thereof set forth
               in such registration statement;

        (iii)  furnish to each seller of Registrable Shares and the underwriters
               of the securities being registered such number of copies of such
               registration statement, each amendment and supplement thereto (in
               each case including all exhibits), the


                                      -6-
<PAGE>

               prospectus included in such registration statement (including
               each preliminary and summary prospectus) and any other prospectus
               filed under Rule 424 or Rule 430-A under the Securities Act, and
               such other documents as such seller or underwriters may
               reasonably request in order to facilitate the disposition of the
               Registrable Shares owned by such seller or the sale of such
               securities by such underwriters;

        (iv)   use its best efforts to register or qualify such Registrable
               Shares under such other securities or blue sky laws of such
               jurisdictions as the managing underwriter and each seller
               reasonably requests, to keep such registration or qualification
               in effect for so long as such registration statement remains in
               effect, and do any and all other acts and things which may be
               reasonably necessary or advisable to enable such seller to
               consummate the disposition of the Registrable Shares owned by
               such seller in such jurisdictions (provided, however, that the
               Company will not be required to (A) qualify generally to do
               business in any jurisdiction where it would not otherwise be
               required to qualify but for this subparagraph, (B) consent to
               general service of process in any such jurisdiction or (C)
               subject itself to any taxation (other than stamp taxes) in any
               such jurisdiction);

        (v)    notify each seller of Registrable Shares promptly after it shall
               receive notice thereof, of the time when such registration
               statement has become effective;

        (vi)   notify each seller of Registrable Shares promptly of any request
               by the Commission for the amending or supplementing of such
               registration statement or prospectus or for additional
               information;

        (vii)  provide a transfer agent and registrar for all Registrable Shares
               sold under the registration not later than the effective date of
               the registration statement;

        (viii) furnish to each Holder participating in the registration a signed
               counterpart, addressed to such Holder (a) of an opinion of
               counsel as to such matters that are customarily covered in an
               opinion of counsel delivered to an underwriter, including that
               the registration is valid and effective and such other matters as
               such Holder may reasonably request and (b) of a "cold comfort"
               letter signed by the independent public accountants who have
               issued a report on the Company's financial statements included in
               the registration statement, covering substantially the same
               matters with respect to such registration statement (and the
               prospectus included therein) and, in the case of such
               accountant's letter, with respect to events subsequent to the
               date of such financial statements, as are customarily delivered
               to underwriters in underwritten public offerings of securities
               and such other financial matters as such Holder may reasonably
               request;

        (ix)   advise each seller of such Registrable Shares, promptly after it
               shall receive notice or obtain knowledge thereof, of the issuance
               of any stop order by the Commission suspending the effectiveness
               of such registration statement or of any order suspending or
               preventing the use of any related prospectus or suspending the
               qualification of any common stock included in such registration
               statement for sale


                                      -7-

               in any jurisdiction or the initiation or threatening of any
               proceeding for such purpose and promptly use reasonable best
               efforts to prevent the issuance of any stop order or to obtain
               its withdrawal if such stop order should be issued;

        (x)    notify each seller of Registrable Shares covered by such
               registration statement at any time when a prospectus relating
               thereto is required to be delivered under the Securities Act,
               upon discovery that, or upon the happening of any event as a
               result of which, the prospectus included in such registration
               statement, as then in effect, includes an untrue statement of a
               material fact or omits to state any material fact required to be
               stated therein or necessary to make the statements therein not
               misleading in the light of the circumstances under which they
               were made, and at the request of any such seller promptly
               prepare, file with the Commission and to furnish such seller a
               reasonable number of copies of a supplement to or an amendment of
               such prospectus as may be necessary so that, as thereafter
               delivered to the purchasers of such securities, such prospectus
               shall not include an untrue statement of a material fact required
               to be stated therein or necessary to make the statements therein
               not misleading in the light of the circumstances under which they
               were made;

        (xi)   otherwise use its reasonable efforts to comply with all
               applicable rules and regulations of the Commission, and make
               available to its securityholders, as required, as soon as
               reasonably practicable, an earnings statement covering the period
               of at least twelve months, but not more than eighteen months,
               beginning with the first full calendar month after the effective
               date of such registration statement, which earnings statement
               shall satisfy the provisions of Section 11(a) of the Securities
               Act, and Rule 158 promulgated thereunder and will furnish to each
               such seller at least two business days prior to the filing
               thereof a copy of any amendment or supplement to such
               registration statement or prospectus and shall not file any
               thereof to which any such seller shall have reasonably objected
               on the grounds that such amendment or supplement does not comply
               in all material respects with the requirements of the Securities
               Act or of the rules or regulations thereunder;

        (xii)  use its reasonable best efforts to list all Registrable Shares
               covered by such registration statement on any securities exchange
               on which similar securities of the Company are then listed;

        (xiii) enter into such customary agreements (including underwriting
               agreements in customary form) and take such other customary
               actions as the Holders of Registrable Shares or the underwriters,
               if any, shall reasonably request in order to expedite or
               facilitate the disposition of such Registrable Shares;

        (xiv)  make available for reasonable inspection by any seller of
               Registrable Shares, any underwriter participating in any
               disposition pursuant to such registration statement and any
               attorney, accountant or other agent retained by any such seller
               or underwriter, all financial and other records, pertinent
               corporate documents and properties of the Company, and cause the
               Company's officers, directors,


                                      -8-
<PAGE>

               employees and independent accountants to supply all information
               reasonably requested by any such sellers, underwriter, attorney,
               accountant or agent in connection with such registration
               statement;

        (xv)   deliver promptly to each Holder participating in an offering who
               so requests the file correspondence and memoranda described
               below, copies of all correspondence between the Commission and
               the Company, its counsel or auditors with respect to the
               registration statement and permit each Holder to do such
               investigation, upon reasonable advance notice, with respect to
               information contained in or omitted from the registration
               statement as it deems reasonably necessary to comply with
               applicable securities laws or the rules and regulations of the
               NASD. Such investigation shall include reasonable access to
               books, records and properties and opportunities to discuss the
               business of the Company with its officers and independent
               auditors, all to such reasonable extent and at such reasonable
               times and as often as any such Holder shall reasonably request;
               and

        (xvi)  permit any Holder of Registrable Shares, which holder, in its
               sole and exclusive judgment, might be deemed to be an underwriter
               or a controlling person of the Company, to participate in the
               preparation of such registration or comparable statement and to
               require the insertion therein of materials, furnished to the
               Company in writing, which in the reasonable judgment of such
               Holder and its counsel should be included.

        If any such registration or comparable statement refers to any Holder by
        name or otherwise as the holder of any securities of the Company and if,
        in its sole and exclusive judgment, such Holder is or might be deemed to
        be a controlling person of the Company, such Holder shall have the right
        to require (i) the insertion therein of language, in form and substance
        satisfactory to such Holder and presented to the Company in writing, to
        the effect that the holding by such Holder of such securities is not to
        be construed as a recommendation by such Holder of the investment
        quality of the Company's securities covered thereby and that such
        holding does not imply that such Holder will assist in meeting any
        future financial requirements of the Company, or (ii) in the event that
        such reference to such Holder by name or otherwise is not required by
        the Securities Act or any similar federal statute then in force, the
        deletion of the reference to such Holder; provided that with respect to
        this clause (ii) such Holder shall furnish to the Company an opinion of
        counsel to such effect, which opinion and counsel shall be reasonably
        satisfactory to the Company.

        The Company may require each Holder of Registrable Shares to be included
        in such registration statement to promptly furnish in writing to the
        Company such information regarding the distribution of the Registrable
        Shares as the Company may from time to time reasonably request and any
        such other information as may be legally required in connection with
        such registration.

(c)     SUSPENSION OF DISPOSITIONS. Each Holder agrees by acquisition of any
        Registrable Shares that, upon receipt of any notice (a "SUSPENSION
        NOTICE") from the Company of the happening of any event of the kind
        which, in the opinion of the Company, requires the


                                      -9-
<PAGE>

        amendment or supplement of any prospectus, such Holder will forthwith
        discontinue disposition of Registrable Shares until such Holder's
        receipt of the copies of the supplemented or amended prospectus (which
        the Company shall prepare and file as promptly as practicable), or until
        it is advised in writing (the "ADVICE") by the Company that the use of
        the prospectus may be resumed, and such Holder has received copies of
        any additional or supplemental filings which are incorporated by
        reference in the prospectus, and, if so directed by the Company, such
        Holder will deliver to the Company all copies, other than permanent file
        copies then in such Holder's possession, of the prospectus covering such
        Registrable Shares current at the time of receipt of such notice. In the
        event the Company shall give any such notice, the time period regarding
        the effectiveness of registration statements set forth in Section
        4(b)(ii) hereof shall be extended by the number of days during the
        period from and including the date of the giving of the Suspension
        Notice to and including the date when each seller of Registrable Shares
        covered by such registration statement shall have received the copies of
        the supplemented or amended prospectus or the Advice.

(d)     REGISTRATION EXPENSES. All expenses incident to the Company's
        performance of or compliance with this Agreement including, without
        limitation, all registration and filing fees, reasonable fees and
        expenses of one legal counsel for all Holders of Registrable Shares to
        be included in the registration statement (up to a maximum of $15,000 in
        the aggregate if such registration is on a Short-Form Registration), all
        fees and expenses associated with filings required to be made with the
        NASD (including, if applicable, the fees and expenses of any "qualified
        independent underwriter" as such term is defined in Schedule E of the
        By-Laws of the NASD, and of its counsel), as may be required by the
        rules and regulations of the NASD, fees and expenses of compliance with
        securities or "blue sky" laws (including reasonable fees and
        disbursements of counsel in connection with "blue sky" qualifications of
        the Registrable Shares), all word processing, duplicating and printing
        expenses (including expenses of printing certificates for the
        Registrable Shares and of printing prospectuses if the printing of
        prospectuses is requested by a Holder of Registrable Shares) (provided,
        however, that the manner and form of printing the registration statement
        and prospectuses shall be at the sole discretion of the Company),
        messenger and delivery expenses, fees and expenses of counsel for the
        Company and its independent certified public accountants (including the
        expenses of any special audit or "cold comfort" letters required by or
        incident to such performance), securities acts liability insurance (if
        the Company elects to obtain such insurance), the fees and expenses of
        any special experts retained by the Company in connection with such
        registration, the fees and expenses of underwriters customarily paid by
        issuers or sellers of securities (including fees paid to a qualified
        independent underwriter but excluding underwriting discounts and
        commissions), and the fees and expenses of other persons retained by the
        Company (all such expenses being herein called "REGISTRATION EXPENSES")
        will be borne by the Company whether or not any registration statement
        becomes effective; provided that in no event shall Registration Expenses
        include any underwriting discounts, commissions, or any out of pocket
        expenses of the Holders (or agents who manage their accounts) other than
        as expressly provided above.

(e)     REQUIREMENTS TO PARTICIPATE. No Holder may participate in any
        registration hereunder unless such Holder (x) agrees to sell such
        Holder's Registrable Shares on the basis


                                      -10-
<PAGE>

        provided in any underwriting arrangements approved by the Company and
        (y) completes and executes all questionnaires, powers of attorney,
        indemnities, underwriting agreements, and other documents required under
        the terms of such underwriting arrangements; provided, however, that no
        such Holder shall be required to make any representations or warranties
        in connection with any such registration other than representations and
        warranties as to (i) such Holder's ownership of such Holder's
        Registrable Shares to be sold or transferred free and clear of all
        liens, claims, and encumbrances, (ii) such Holder's power and authority
        to effect such transfer, and (iii) such matters pertaining to compliance
        with securities laws as may be reasonably requested; provided further,
        however, that the obligation of such Holder to indemnify pursuant to any
        such underwriting arrangements shall be several, not joint and several,
        among such Persons selling securities thereunder, and the liability of
        each such Holder will be in proportion to and limited to the net amount
        received by such Holder from the sale of such Holder's Registrable
        Shares pursuant to such registration.

5.      INDEMNIFICATION

(a)     The Company agrees to indemnify and hold harmless, to the fullest extent
        permitted by law, each seller of Registrable Shares, and each of its
        employees, advisors, agents, representatives, partners, officers,
        directors and affiliates and each Person who controls such seller
        (within the meaning of the Securities Act or the Exchange Act)
        (collectively, the "SELLER AFFILIATES") and each other Person who
        participated as an underwriter in the offering or sale of such
        securities and each of its employees, advisors, agents, representatives,
        partners, officers, directors and affiliates and each Person who
        controls such underwriters (within the meaning of the Securities Act or
        the Exchange Act) (i) against any and all losses, claims, damages,
        liabilities and expenses (including, without limitation, reasonable
        attorneys' fees except as limited by Section 5(c) below) arising out of
        or caused by any untrue or alleged untrue statement of a material fact
        contained in any registration statement, preliminary prospectus, final
        prospectus, summary prospectus, or any amendment thereof or supplement
        thereto if the Company shall have furnished any amendments or
        supplements, or any omission or alleged omission of a material fact
        required to be stated therein or necessary to make the statements
        therein not misleading, (ii) against any and all losses, claims,
        damages, liabilities and expenses whatsoever, as incurred, to the extent
        of the aggregate amount paid in settlement of any litigation or
        investigation or proceeding by any governmental agency or body,
        commenced or threatened, or of any claim whatsoever based upon any such
        untrue statement or omission or alleged untrue statement or omission,
        and (iii) against any and all costs and expenses (including reasonable
        fees and disbursements of counsel) as may be reasonably incurred in
        investigating, preparing, or defending against any litigation, or
        investigation or proceeding by any governmental agency or body,
        commenced or threatened, or any claim whatsoever based upon any such
        untrue statement or omission or alleged untrue statement or omission, to
        the extent that any such expense or cost is not paid under subparagraph
        (i) or (ii) above; except insofar as the same are made in reliance upon
        and in strict conformity with information furnished in writing to the
        Company by such seller or any Seller Affiliate for use therein. The
        reimbursements required by this Section 5(a) will be made by periodic
        payments during the course of the investigation or defense, as and when
        bills are received or expenses incurred.


                                      -11-
<PAGE>

(b)     In connection with any registration statement in which a seller of
        Registrable Shares is participating, each such seller will furnish to
        the Company in writing such information and affidavits as the Company
        reasonably requests for use in connection with any such registration
        statement or prospectus and, to the fullest extent permitted by law,
        each such seller will indemnify the Company, its directors, agents,
        officers and each Person who controls the Company (within the meaning of
        Section 15 of the Securities Act or Section 20 of the Exchange Act) to
        the same extent as the foregoing indemnity from the Company to such
        seller and its Seller Affiliates, but only to the extent that such
        untrue statement or alleged untrue statement or omission or alleged
        omission is contained in any information or affidavit so furnished in
        writing by such seller or any of its Seller Affiliates for specific
        inclusion in such registration statement; provided that the obligation
        to indemnify will be several, not joint and several, among such sellers
        of securities thereunder, and the liability of each such seller will be
        in proportion and limited to the net amount received by such seller from
        the sale of such seller's Registrable Securities pursuant to such
        registration statement.

(c)     Any Person entitled to indemnification hereunder will (i) give prompt
        written notice to the indemnifying party of any claim with respect to
        which it seeks indemnification (provided that the failure to give such
        notice shall not limit the rights of such Person) and (ii) unless in
        such indemnified party's reasonable judgment a conflict of interest
        between such indemnified and indemnifying parties may exist with respect
        to such claim, permit such indemnifying party to assume the defense of
        such claim with counsel reasonably satisfactory to the indemnified
        party; provided, however, that any person entitled to indemnification
        hereunder shall have the right to employ separate counsel and to
        participate in the defense of such claim, but the fees and expenses of
        such counsel shall be at the expense of such person unless (X) the
        indemnifying party has agreed to pay such fees or expenses, (Y) the
        indemnifying party shall have failed to assume the defense of such claim
        and employ counsel reasonably satisfactory to such person or (Z) in the
        reasonable judgment of any indemnified party, a conflict of interest may
        exist between such indemnified party and any other of such indemnified
        parties with respect to such claim. An indemnifying party will not be
        obligated to pay the fees and expenses of more than one counsel for all
        parties indemnified by such indemnifying party with respect to such
        claim. If such defense is assumed by the indemnified party as permitted
        hereunder, the indemnifying party will not be subject to any liability
        for any settlement made by the indemnified party without its written
        consent (which consent shall not be unreasonably withheld). If such
        defense is assumed by the indemnifying party pursuant to the provisions
        hereof, such indemnifying party shall not settle or otherwise compromise
        the applicable claim unless (1) such settlement or compromise contains a
        full and unconditional release of the indemnified party from all
        liabilities arising out of such proceeding or (2) the indemnified party
        otherwise consents in writing.

(d)     Each party hereto agrees that, if for any reason the indemnification
        provisions contemplated by Section 5(a) or Section 5(b) are unavailable
        to or insufficient to hold harmless an indemnified party in respect of
        any losses, claims, damages, liabilities or expenses (or actions in
        respect thereof) referred to therein, then each indemnifying party shall
        contribute to the amount paid or payable by such indemnified party as a
        result of such losses, claims, liabilities, or expenses (or actions in
        respect thereof) in such


                                      -12-
<PAGE>

        proportion as is appropriate to reflect the relative fault of the
        indemnifying party and the indemnified party as well as any other
        relevant equitable considerations. The relative fault of such
        indemnifying party and indemnified party shall be determined by
        reference to, among other things, whether the untrue or alleged untrue
        statement of a material fact or omission or alleged omission to state a
        material fact relates to information supplied by such indemnifying party
        or indemnified party, and the parties' relative knowledge, access to
        information and opportunity to correct or prevent such statement or
        omission. 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 (even if the Holders were treated as one entity
        for such purpose) or by any other method of allocation which does not
        take account of the equitable considerations referred to in this Section
        5(d). The amount paid or payable by an indemnified party as result of
        the losses, claims, damages, liabilities or expenses (or actions in
        respect thereof) referred to above shall be deemed to include any legal
        or other fees or expenses reasonably incurred by such indemnified party
        in connection with investigating or, except as provided in Section 5(c),
        defending any such action or claim. Notwithstanding the provisions of
        this Section 5(d), no Holder shall be required to contribute an amount
        greater than the dollar amount of the proceeds received by such Holder
        with respect to the sale of any Registrable Shares. 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. The Holders'
        obligations in this Section 5(d) to contribute shall be several in
        proportion to the amount of Registrable Shares registered by them and
        not joint.

(e)     The indemnification provided for under this Agreement will remain in
        full force and effect regardless of any investigation made by or on
        behalf of the indemnified party or any officer, director or controlling
        Person of such indemnified party and will survive the transfer of
        securities.

6.      REPRESENTATIONS AND WARRANTIES

        The Company represents and warrants to the Holders that:

(a)     The Company is a corporation duly organized and validly existing and in
        good standing under the laws of the State of Delaware, and has corporate
        power and corporate authority to own, operate, and lease its properties
        and conduct its business as now conducted. The Company is duly qualified
        to do business and is in good standing in all jurisdictions in which the
        failure to so qualify would have a material adverse effect on the
        operations, business, financial conditions, assets, or liabilities of
        the Company and its subsidiaries, taken as a whole.

(b)     The Company has the corporate power and is duly authorized and empowered
        to enter into and perform its obligations under this Agreement. This
        Agreement has been duly and validly executed, issued, and delivered and
        constitutes the legal, valid, and binding obligation of the Company.


                                      -13-
<PAGE>

(c)     The execution, delivery, and performance of this Agreement by the
        Company shall not, by the lapse of time, the giving of notice or
        otherwise, constitute a violation of any applicable statute, law, rule
        or regulation of any governmental authority, any applicable provision
        contained in the certificate of incorporation or bylaws of the Company
        or contained in any agreement, instrument, or document to which the
        Company is a party or by which it is bound, or any order, ruling,
        judgment or decree of any court, arbitral body or governmental
        authority.

7.      ARBITRATION AND DISPUTE RESOLUTION

        The parties hereto agree that any and all disputes, claims or
controversies arising out of or relating to this Agreement that are not resolved
by their mutual agreement shall be submitted to final and binding arbitration
before JAMS, or its successor, pursuant to the United States Arbitration Act, 9
U.S.C. Sec. 1, et seq. Either party may commence the arbitration process called
for in this Agreement by filing a written demand for arbitration with JAMS, with

share equally in its costs. The provisions of this paragraph may be enforced by
any court of competent jurisdiction, and the party seeking enforcement shall be
entitled to an award of all costs, fees and expenses, including attorneys fees,

agrees to:

(a)     Make and keep available adequate current public information, as those
        terms are understood and defined in Rule 144 under the Securities Act,
        at all times after it has become subject to the reporting requirements
        of the Exchange Act;

(b)     Use its best efforts to 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

(c)     Furnish to each Holder of Registrable Shares forthwith upon request a
        written statement by the Company as to its compliance with the reporting
        requirements of such Rule 144 ninety (90) days after any registration
        statement covering a public offering of securities of the Company under
        the Securities Act shall have become effective, and of the Securities
        Act and the Exchange Act, a copy of the most recent annual or quarterly
        report of the Company, and such other reports and documents so filed by
        the Company as such Holder may reasonably request availing itself of any
        rule or regulation of the Commission allowing such Holder to sell any
        Registrable Shares without registration.

14.     WAIVER

sought to be enforced.

any other right or remedy available to it, to an injunction restraining such
breach or a threatened breach and/or to specific performance of any such
provision of this Agreement, and in either case no bond or other security shall
be required in connection therewith, and the parties hereby consent to such
injunction and to the ordering of specific performance.

remaining provisions shall be severable and enforceable in accordance with their
terms.

18.     GOVERNING LAW

        This Agreement shall be governed by, interpreted under and construed in
accordance with the internal laws of the State of New York applicable to

claim that any such enforcement proceeding brought in any such court has been
brought in an inconvenient forum. Nothing herein shall affect the right of any
