                               required to permit sale or disposition as set
                               forth in the written request.

                     (e)        Notwithstanding the foregoing, if the managing
                                underwriter of an underwritten public offering
                                determines and advises in writing that the
                                inclusion of all Registrable Securities proposed
                                to be included in the underwritten public
                                offering, together with any shares proposed to
                                be sold by the Company for its own account and
                                any other issued and outstanding shares of
                                Common Stock proposed to be included therein by
                                holders other than the holders of Registrable
                                Securities (such other holders' shares
                                hereinafter collectively referred to as the
                                "Other Shares"), would interfere with the
                                successful marketing of the securities proposed
                                to be included in the underwritten public
                                offering, including the price at which such
                                securities can be sold, then the number of such
                                shares of persons other than the Company that
                                otherwise would be included in such underwritten
                                public offering shall be excluded from such
                                underwritten public offering in a number deemed
                                necessary by such managing underwriter, first by
                                excluding, to the extent necessary, other shares
                                held by persons who have not exercised
                                contractual rights to include such Shares in the
                                offering pursuant to the Prior Registration
                                Rights Agreements (as hereinafter defined), and
                                then, to the extent necessary, by excluding
                                Registrable Securities participating in such
                                underwritten public offering, pro rata, based on
                                the number of shares of Registrable Securities
                                each holder proposes to include; and, then,
                                excluding to the extent necessary, other Shares
                                proposed to be included by the holders of other
                                Shares who have exercised registration rights
                                granted to them under registration rights
                                agreements of the Company in effect on the date
                                hereof or any other registration rights in
                                effect on the date hereof (collectively, the
                                "Prior Registration Rights Agreements").

                     (f)       All Shares and Warrant Shares that are not
                               included in an underwritten public offering
                               pursuant to Section 2.3 shall be withheld from
                               the market by the holders thereof for a period,
                               not to exceed 12 months following a public
                               offering, that the managing underwriter
                               reasonably determines is necessary in order to
                               effect the underwritten public offering. The
                               holders of such Shares and the Warrant Shares
                               shall execute such documentation as the managing
                               underwriter reasonably requests to evidence this
                               lock-up.






                     (g)       The registration rights provided by this
                               Agreement shall expire with respect to any

                               Stockholder, such Registrable Security; (ii) the
                               date on which such Registrable Security is
                               eligible for resale under Rule 144 without regard
                               to the volume limitations thereof; and (iii) five
                               years from the date hereof.

                               therewith as may be necessary to keep such
                               Registration Statement effective for, in the case
                               of a Required Registration under Section 2.2, the
                               period set forth in Section 2.2(b) and, in the
                               case of a Piggyback Registration under Section
                               2.3, six months, and to comply with the
                               provisions of the Securities Act with respect to
                               the sale or other disposition of all Registrable
                               Securities covered by such Registration
                               Statement;

                     (c)        furnish to each Selling Stockholder such number
                                of copies of any summary prospectus or other
                                prospectus, including a preliminary prospectus
                                and all amendments and supplements thereto, in
                                conformity with the requirements of the
                                Securities Act, and such other documents as such
                                Selling Stockholder may reasonably request in
                                order to facilitate the public sale or other
                                disposition of such Registrable Securities;
                                provided, however, that no such prospectus need
                                be furnished more than, in the case of a
                                Required Registration under Section 2.2, six
                                months after the conclusion of the period set
                                forth in Section 2.2(b) and, in the case of a

                                months after the effective date of the
                                Registration Statement related thereto;






                        (d)     use its best  efforts to register or qualify the
                                Registrable    Securities    covered   by   such
                                Registration  Statement  under the securities or
                                blue  sky  laws  of such  jurisdictions  as each
                                Selling Stockholder shall reasonably request and
                                do any and all other acts or things which may be
                                reasonably necessary or advisable to enable such
                                holder to  consummate  the public  sale or other
                                disposition  in  such   jurisdictions   of  such
                                Registrable Securities;  provided, however, that
                                the Company  shall not be required to consent to
                                general  service  of  process,   qualify  to  do
                                business as a foreign corporation where it would
                                not be  otherwise  required to qualify or submit
                                to  liability  for state or local taxes where it
                                is not  liable  for such  taxes or  provide  any
                                undertaking   or   make   any   change   in  its
                                Certificate of Incorporation; and

                     (e)        at any time when a prospectus covered by such
                                Registration Statement is required to be
                                delivered under the Securities Act within the
                                appropriate period mentioned in Section 2.2(b)
                                or Section 2.3(b) hereof, as the case may be,
                                notify each Selling Stockholder of 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 a material fact
                                required to be stated therein or necessary to
                                make the statements therein not misleading in
                                the light of the circumstances then existing
                                and, at the request of such seller, prepare,
                                file and furnish to 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 shares, such prospectus shall
                                not include an untrue statement of a material
                                fact or omit to state a material fact required
                                to be stated therein or necessary to make the
                                statement therein not misleading in the light of
                                the circumstances then existing. The Company may
                                delay amending or supplementing the prospectus
                                for a period of up to 90 days if the Company is
                                then engaged in negotiations regarding a
                                material transaction that has not been publicly
                                disclosed, and the Selling Stockholders shall
                                suspend their sale of Shares until an
                                appropriate supplement or prospectus has been
                                forwarded to them or the proposed transaction is
                                abandoned.

           Notwithstanding the foregoing, with respect to the proposed
           Registration of Registrable Securities pursuant to Section 2.3
           hereof, the Company may withdraw or cease proceeding with any
           proposed Registration of Registrable Securities if it has withdrawn
           or ceased proceeding with the proposed Registration of Common Stock
           of the Company with which the Registration of such Registrable
           Securities was to be included.

           2.5       Expenses. The Company shall pay all Registration Expenses
                     incurred by the Company in complying with this Section 2.

           2.6       Information Furnished by Purchaser. It shall be a condition
                     precedent to the Company's obligations under this Agreement
                     as to any Selling Stockholder that each Selling Stockholder
                     furnish to the Company in writing such information
                     regarding such Selling Stockholder and the distribution
                     proposed by such Selling Stockholder as the Company may
                     reasonably request.






           2.7       Indemnification.

                2.7.1   Company's Indemnification of Purchasers. The Company
                        shall indemnify each Selling Stockholder, each of its
                        officers, directors and constituent partners, and each
                        person controlling (within the meaning of the Securities
                        Act) such Selling Stockholder, against all claims,
                        losses, damages or liabilities (or actions in respect
                        thereof) suffered or incurred by any of them, to the
                        extent such claims, losses, damages or liabilities arise
                        out of or are based upon any untrue statement (or
                        alleged untrue statement) of a material fact contained
                        in any prospectus or any related Registration Statement
                        incident to any such Registration, or 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, or any violation by
                        the Company of any rule or regulation promulgated under
                        the Securities Act applicable to the Company and
                        relating to actions or inaction required of the Company
                        in connection with any such Registration; and the
                        Company will reimburse each such Selling Stockholder,
                        each of its officers, directors and constituent partners
                        and each person who controls any such Selling
                        Stockholder, for any reasonable, documented legal and
                        other expenses incurred in connection with investigating
                        or defending any such claim, loss, damage, liability or
                        action; provided, however, that the indemnity contained
                        in this Section 2.7.1 shall not apply to amounts paid in
                        settlement of any such claim, loss, damage, liability or
                        action if settlement is effected without the consent of
                        the Company (which consent shall not unreasonably be
                        withheld); and provided, further, that the Company will
                        not be liable in any such case to the extent that any
                        such claim, loss, damage, liability or expense arises
                        out of or is based upon any untrue (or alleged untrue)
                        statement or omission based upon written information
                        furnished to the Company by such Selling Stockholder,
                        underwriter, controlling person or other indemnified
                        person and stated to be for use in connection with the
                        offering of securities of the Company.






                2.7.2   Selling Stockholder's Indemnification of Company. Each
                        Selling Stockholder shall indemnify the Company, each of
                        its directors and officers, each underwriter, if any, of
                        the Company's securities covered by a Registration
                        Statement, each person who controls the Company or such
                        underwriter within the meaning of the Securities Act,
                        and each other Selling Stockholder, each of its
                        officers, directors and constituent partners and each
                        person controlling such other Selling Stockholder,
                        against all claims, losses, damages and liabilities (or
                        actions in respect thereof) suffered or incurred by any
                        of them and arising out of or based upon any untrue
                        statement (or alleged untrue statement) of a material
                        fact contained in such Registration Statement or related
                        prospectus, or 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, or any violation by such Selling Stockholder
                        of any rule or regulation promulgated under the
                        Securities Act applicable to such Selling Stockholder
                        and relating to actions or inaction required of such
                        Selling Stockholder in connection with the Registration
                        of the Registrable Securities pursuant to such
                        Registration Statement; and will reimburse the Company,
                        such other Selling Stockholders, such directors,
                        officers, partners, persons, underwriters and
                        controlling persons for any reasonable, documented legal
                        and other expenses incurred in connection with
                        investigating or defending any such claim, loss, damage,
                        liability or action; provided, however, that such
                        indemnification and reimbursement shall be to the
                        extent, but only to the extent, that such untrue
                        statement (or alleged untrue statement) or omission (or
                        alleged omission) is made in such Registration Statement
                        or prospectus in reliance upon and in conformity with
                        written information furnished to the Company by such
                        Selling Stockholder and stated to be for use in
                        connection with the offering of Registrable Securities.






                2.7.3   Indemnification Procedure. Promptly after receipt by an
                        indemnified party under this Section 2.7 of notice of
                        the commencement of any action which may give rise to a
                        claim for indemnification hereunder, such indemnified
                        party will, if a claim in respect thereof is to be made
                        against an indemnifying party under this Section 2.7,
                        notify the indemnifying party in writing of the
                        commencement thereof and generally summarize such
                        action. The indemnifying party shall have the right to
                        participate in and to assume the defense of such claim,
                        and shall be entitled to select counsel for the defense
                        of such claim with the approval of any parties entitled
                        to indemnification, which approval shall not be
                        unreasonably withheld. Notwithstanding the foregoing,
                        the parties entitled to indemnification shall have the
                        right to employ separate counsel (reasonably
                        satisfactory to the indemnifying party) to participate
                        in the defense thereof, but the fees and expenses of
                        such separate counsel shall be at the expense of such
                        indemnified parties unless the named parties to such
                        action or proceedings include both the indemnifying
                        party and the indemnified parties and the indemnifying
                        party or such indemnified parties shall have been
                        advised by counsel that there are one or more legal
                        defenses available to the indemnified parties which are
                        different from or additional to those available to the
                        indemnifying party (in which case, if the indemnified
                        parties notify the indemnifying party in writing that
                        they elect to employ separate counsel at the reasonable
                        expense of the indemnifying party, the indemnifying
                        party shall not have the right to assume the defense of
                        such action or proceeding on behalf of the indemnified
                        parties, it being understood, however, that the
                        indemnifying party shall not, in connection with any
                        such action or proceeding or separate or substantially
                        similar or related action or proceeding in the same
                        jurisdiction arising out of the same general allegations
                        or circumstances, be liable for the reasonable,
                        documented fees and expenses of more than one separate
                        counsel at any time for all indemnified parties, which
                        counsel shall be designated in writing by the Purchasers
                        of a majority of the Registrable Securities).

                2.7.4   Contribution. If the indemnification provided for in
                        this Section 2.7 from an indemnifying party is
                        unavailable to an indemnified party hereunder in respect
                        to any losses, claims, damages, liabilities or expenses
                        referred to herein, then the indemnifying party, in lieu
                        of indemnifying such indemnified party, shall contribute
                        to the amount paid or payable by such indemnified party
                        as a result of such losses, claims, damages, liabilities
                        or expenses in such proportion as is appropriate to
                        reflect the relative fault of the indemnifying party and
                        indemnified party in connection with the statements or
                        omissions which result in such losses, claims, damages,
                        liabilities or expenses, 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 the omission or alleged omission to state a
                        material fact relates to information supplied by such
                        indemnifying party or indemnified party and the parties'
                        relative intent, knowledge, access to information
                        supplied by such indemnifying party or indemnified party
                        and opportunity to correct or prevent such statement or
                        omission. The amount paid or payable by a party as a
                        result of the losses, claims, damages, liabilities and
                        expenses referred to above shall be deemed to include
                        any documented legal or other fees or expenses
                        reasonably incurred by such party in connection with
                        investigating or defending any action, suit, proceeding
                        or claim, or in collecting such indemnity or
                        reimbursement from the indemnifying party.



3. Covenants of the Company.

           The Company agrees to:

           (a)       Notify the holders of Registrable Securities included in a
                     Registration Statement (i) of the issuance by the
                     Commission of any stop order suspending the effectiveness
                     of such Registration Statement and (ii) upon learning of
                     the initiation of any proceedings for the purpose of
                     suspending such effectiveness, the existence of such
                     proceedings. The Company will make every reasonable effort
                     to prevent the issuance of any stop order and, if any stop
                     order is issued, to obtain the lifting thereof at the
                     earliest possible time.






           (b)       If the Common Stock is then listed on a national securities
                     exchange, use its best efforts to cause the Registrable
                     Securities to be listed on such exchange. If the Common
                     Stock is not then listed on a national securities exchange,
                     use its best efforts to facilitate the reporting of the
                     Registrable Securities on Nasdaq.

           (c)       Take all other reasonable actions necessary to expedite and
                     facilitate disposition of the Registrable Securities by the
                     holders thereof pursuant to the Registration Statement.

           (d)       With a view to making available to the holders of
                     Registrable Securities the benefits of Rule 144 promulgated
                     under the Securities Act and any other rule or regulation
                     of the Commission that may at any time permit the
                     Purchasers to sell securities of the Company to the public
                     without registration, the Company agrees to:

                     (i)       make and keep adequate current public information
                               with respect to the Company available, as those
                               terms are understood and defined in Rule 144, at
                               all times after 90 days after the effective date
                               of the first Registration Statement filed by the
                               Company for the offering of its securities to the
                               general public;

                     (ii)      file with the Commission in a timely manner all
                               reports and other documents required of the
                               Company under the Securities Act and the
                               Securities Exchange Act of 1934 (the "1934 Act");
                               and

                     (iii)     furnish to each holder of Shares, so long as such
                               holder of Shares owns any Shares, forthwith upon
                               written request (a) a written statement by the
                               Company as to whether it has complied with the
                               reporting requirements of Rule 144, the
                               Securities Act and the 1934 Act, (b) a copy of
                               the most recent annual or quarterly report of the

                               filed by the Company and (c) such other
                               information as may be reasonably requested and as
                               is publicly available in availing the holders of
                               Shares of any rule or regulation of the
                               Commission which permits the selling of any such
                               securities without registration.

           (e)       Prior to the filing of a Registration Statement or any
                     amendment thereto (whether pre-effective or
                     post-effective), and prior to the filing of any prospectus
                     or prospectus supplement related thereto, the Company will
                     provide each Selling Stockholder with copies of all pages
                     thereto, if any, which reference such Selling Stockholder.

           (f)       If the Registration Statement relates to an underwritten

                     including, without limitation, customary indemnification
                     and contribution obligations, with the underwriter's
                     representative.






           (g)       Make generally available to its security holders as soon as
                     practicable, but not later than forty five (45) days after
                     the close of the period covered thereby, the Company's
                     financial statements as filed with the Commission.

           (h)       At the request of the Investors who hold a majority in
                     interest of the Registrable Securities being sold,
                     furnish to the underwriters, if any, on the date that

                     Registrable Securities sold pursuant to the Registration
                     Statement and to enable such certificates to be in such
                     denominations and registered in such names as the

                     hereof and no party shall be liable or bound to any other

                     practicable, be modified so as to make it valid, legal and

                     way be affected or impaired thereby. To the extent
                     permitted by law, the parties waive the benefit of any
                     provision of law that renders any provision of the

                     particular instance, either retroactively or prospectively,
                     and either for a specified period of time or indefinitely),

                     the fifth day following mailing by registered or certified
                     mail, return receipt requested, postage prepaid, addressed
                     to the Company at its address as set forth in the Purchase
                     Agreement and to the Purchaser at its address as shown on
                     the books of the Company.

           (g)       The titles of the paragraphs and subparagraphs of this

                     provided herein, no failure or delay on the part of any
                     party in exercising any right, power or remedy hereunder
                     shall operate as a waiver thereof, nor shall any single or
                     partial exercise of any such right, power or remedy
                     preclude any other or further exercise thereof or the
                     exercise of any other right, power or remedy.

                     IN WITNESS WHEREOF, the parties have executed this
