         4. REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS.

              (a) INVESTOR REPRESENTATIONS, WARRANTIES AND COVENANTS. The
Investor represents, warrants and agrees as follows:

                   (1) The Investor has received and reviewed a copy of the
         Memorandum, and all appendices and supplements (if any) thereto,
         relating to the Shares and understands that no Person has been
         authorized to give any information or to make any representations that
         were not contained in the Memorandum, and the Investor has not relied
         on any such other information or representations in making a decision
         to purchase the Investor Shares. The Investor has had access to such
         financial and other information and has had the opportunity to ask
         questions and receive answers as deemed necessary in respect of the
         decision to purchase the Investor Shares, and has consulted with its
         advisors concerning the proposed investment in the Company. The
         Investor understands


                                       2



         that an investment in the Company involves a high degree of risk for
         the reasons, among others, set forth under the caption "Risk Factors"
         in the Memorandum.

                   (2) The Investor has decided to invest in the Shares and, in
         making the decision to so invest, is not in any way relying on the fact
         that any other Person has decided to invest in the Shares.

                   (3) The Investor represents that the Investor (or, if
         applicable, each managed account on whose behalf the Investor Shares
         are being purchased by such Investor) is an "accredited investor" as
         defined in Rule 501 under the Securities Act of 1933, as amended (the
         "SECURITIES ACT"), as certified by the Investor in the Investor
         Questionnaire attached hereto as ANNEX I. The Investor further
         represents that the Investor (or, if applicable, each managed account
         on whose behalf the Investor Shares are being purchased) has such
         knowledge and experience in financial and business matters as to be
         capable of evaluating the merits and risk of an investment in the
         Shares and can bear the economic risk of loss of the entire investment
         in the Shares being purchased.

                   (4) The Investor understands and expressly acknowledges and
         agrees that none of the Shares has been, or will be, registered or
         qualified under the Securities Act, or under any applicable securities
         laws of any State of the United States ("APPLICABLE STATE LAW") and
         therefore may not be offered, sold, transferred, assigned, pledged,
         hypothecated or otherwise disposed of, directly or indirectly, unless
         subsequently registered or qualified under the Securities Act and under
         Applicable State Law or unless an exemption from the registration
         requirements of the Securities Act and Applicable State Law is
         available, in each case to the extent permitted by the terms of this
         Agreement.

                   (5) The Investor understands and agrees that all certificates
         representing the Investor Shares shall bear a legend which will be
         substantially in the form of the following:

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN
                  ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE
                  SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY
                  APPLICABLE STATE SECURITIES OR "BLUE SKY" LAWS ("APPLICABLE
                  STATE LAW"). THESE SECURITIES MAY NOT BE OFFERED, SOLD,
                  PLEDGED, TRANSFERRED OR HYPOTHECATED OR OTHERWISE ASSIGNED IN
                  THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION FROM
                  REGISTRATION UNDER THE ACT OR APPLICABLE STATE LAW RELATING TO
                  DISPOSITION OF SECURITIES."


                                       3



                   (6) The Investor (or, if applicable, each managed account on
         whose behalf the Investor Shares are being purchased by the Investor)
         will acquire the Investor Shares pursuant to this Agreement for its own
         account for investment and not with a view to, or in connection with,
         the resale or distribution thereof or in any arrangement or
         understanding with any other persons regarding the distribution of such
         Investor Shares. The Investor hereby covenants and agrees that, during
         the six month period following the Closing, the Investor shall execute
         a lockup agreement, containing a restriction on the sale of Investor
         Shares for a period terminating on the earlier of the ninetieth day
         following closing of a primary offering by the Company or the six month
         anniversary of the Closing, and other standard terms and conditions,
         with any requesting underwriter participating in a primary offering (as
         defined in Section 5(a)(1) below).

                   (7) The Investor hereby covenants and agrees with the Company
         not to, directly or indirectly, sell, offer, contract or grant any
         option to sell (including without limitation any short sale), pledge,
         transfer, establish a "put equivalent position" as such term is defined
         by Rule 16a-1(h) under the Securities Exchange Act of 1934, as amended
         (the "EXCHANGE ACT"), or otherwise dispose of any Investor Shares,
         options or warrants to acquire Investor Shares, or securities
         exchangeable or exercisable for or convertible into Investor Shares
         owned either of record or beneficially (as defined in Rule 13d-3 under
         the Exchange Act) by the Investor or publicly announce the Investor's
         intention to do any of the foregoing or enter into any swap or other
         arrangement that transfers to another, in whole or in part, any of the
         economic benefits or risks of ownership of the Investor Shares, prior
         to the date on which the Registration Statement (as defined in Section
         5(a)(2)) is declared effective (other than in connection with a sale
         pursuant to a registration statement effected under Section 5(a)(1)
         hereof).

                   (8) The Investor hereby covenants and agrees with the Company
         not to make any sale of the Investor Shares without causing the
         prospectus delivery requirement under the Securities Act to be
         satisfied or otherwise complying with the Securities Act, and the
         Investor acknowledges and agrees that the Investor Shares are not
         transferable on the books of the Company unless the certificate
         submitted to the transfer agent evidencing the Investor Shares is
         accompanied by (a) a separate certificate (i) in the form of ANNEX V
         hereto, (ii) executed by an officer of, or other authorized person
         designated by, the Investor, and (iii) to the effect that (A) the
         Investor Shares have been sold in accordance with a registration
         statement pursuant to Section 5 hereof and (B) the requirement of
         delivering a current prospectus has been satisfied; or (b) an opinion
         of counsel reasonably satisfactory to the Company stating that an
         exemption from registration is available under the Securities Act. The
         Investor acknowledges that there may be times when the Company may
         suspend the use of the prospectus forming a part of a registration
         statement in the event that, and during such period as, pending
         negotiations relating to, or consummation of, a transaction, or the
         occurrence of any other event, would require additional disclosure of
         material information by the Company in the registration statement and
         the Company determines that disclosing such information would (x)
         adversely affect the Company, (y) make it impractical or inadvisable to
         cause


                                       4



         the registration statement to be filed or to become effective or
         to amend or supplement the registration statement or (z) otherwise
         render the Company unable to comply with the requirements of the
         Securities and Exchange Commission (the "COMMISSION"). In such event,
         subject to the last sentence of this Section 4(a)(8), the Company may
         suspend the use of such prospectus until such time as an amendment to
         such registration statement has been filed by the Company and declared
         effective by the Commission, or until such time as the Company has
         filed an appropriate report with the Commission pursuant to the
         Exchange Act. The Investor hereby covenants and agrees that it will not
         sell any Investor Shares pursuant to said prospectus during the period
         commencing at the time at which the Company gives the Investor written
         notice of the suspension of the use of said prospectus and ending the
         date on which the Company gives the Investor written notice that the
         Investor may thereafter effect sales pursuant to said prospectus.
         Anything herein to the contrary notwithstanding, the Company does not
         have the right to suspend the use of such prospectus for a period of
         more than forty-five (45) business days per suspension and the Company
         may not exercise this right to suspend the use of such prospectus more
         than twice in any twelve month period.

                   (9) The execution and delivery of this Agreement by the
         Investor and the performance of this Agreement and the consummation by
         the Investor or the Investor's advisory clients, as the case may be, of
         the transactions contemplated hereby have been duly authorized by all
         necessary (corporate, in the case of a corporation) action of the
         Investor and, if applicable, the Investor's advisory clients; and this
         Agreement, when duly executed and delivered by the Investor, will
         constitute a valid and legally binding instrument, enforceable in
         accordance with its terms against the Investor or any of the Investor's
         advisory clients, as the case may be.

                   (10) The Investor represents that:

                        (A) If the Investor is a corporation, it is a
              corporation duly incorporated, validly existing and in good
              standing under the laws of the jurisdiction of its incorporation,
              with full power and authority (corporate and other) to perform its
              obligations under this Agreement. If the Investor is a limited
              liability company, it is a limited liability company duly
              organized, validly existing and in good standing under the laws of
              the jurisdiction of its incorporation, with full power and
              authority (limited liability company and other) to perform its
              obligations under this Agreement. The execution and delivery of
              this Agreement and the performance by the Investor of the
              transactions contemplated hereby have been duly authorized by all
              necessary corporate or other action of the Investor.

                        (B) If the Investor is a corporation acting in an
              advisory capacity, it is a corporation duly organized, validly
              existing and in good standing under the laws of the jurisdiction
              of its incorporation, with full power and authority (corporate and
              other) to act on behalf of its advisory clients under this
              Agreement. If the Investor is a limited liability company acting
              in an advisory capacity, it is a limited liability company duly
              organized, validly existing and in good


                                       5



              standing under the laws of the jurisdiction of its incorporation,
              with full power and authority (corporate and other) to act on
              behalf of its advisory clients under this Agreement.

                        (C) If the Investor is a trust, the trustee thereunder
              has been duly appointed as trustee of such Investor with full
              power and authority to act on behalf of such Investor and to
              perform the obligations of such Investor under this Agreement.
              Furthermore, the trustee under such trust has independently
              determined that the purchase of the Investor Shares is a suitable
              investment for such trust as authorized by the terms thereof and
              applicable laws and regulations.

                        (D) If the Investor is a limited partnership, it is a
              limited partnership duly organized, validly existing and in good
              standing under the laws of the jurisdiction of its organization,
              with full power and authority to perform its obligations under
              this Agreement.

                        (E) If the Investor is a limited partnership acting in
              an advisory capacity, it is a limited partnership duly organized,
              validly existing and in good standing under the laws of the
              jurisdiction of its organization, with full power and authority to
              act on behalf of its advisory clients under this Agreement.

                        (F) If the Investor is a corporation, limited liability
              company, partnership, trust or other form of business entity, the
              execution and delivery of this Agreement will not contravene or
              result in a default under any provision of existing law or
              regulations to which the Investor is subject, the provisions of
              its trust instrument, charter, by-laws or other governing
              documents or any indenture, mortgage or other agreement or
              instrument to which it is a party or by which it is bound and does
              not require on its part any approval, authorization, license or
              filing from or with any foreign, federal, state or municipal board
              or agency which has not been obtained or duly made.

                        (G) If the Investor is an individual, the Investor has
              full power and authority to perform its obligations under this
              Agreement.

                   (11) The Investor agrees to complete and execute and return
         to the Company (a) the Investor Questionnaire attached as ANNEX I to
         this Agreement representing that the Investor is investing in Shares as
         an "accredited investor;" (b) if the Investor is acting on behalf of a
         managed account in the purchase of any Investor Shares, the Managed
         Accounts Representation Letter attached as ANNEX II to this Agreement;
         and (c) the Registration Statement Questionnaire attached as ANNEX III,
         in each case together with an executed signature page to this
         Agreement. The Investor represents and warrants that the answers
         thereto are true and correct as of the date hereof and will be true and
         correct as of the effective date of the Registration Statement (as
         defined in Section 5). If any of the answers provided by the Investor
         in the questionnaires change prior to the effective date of the
         Registration Statement, the Investor will provide the Company with


                                       6



         prompt written notice of such changes. The Investor further represents
         and warrants that it is not purchasing the Investor Shares on behalf of
         any managed account other than as listed in the Managed Account
         Representation Letter.

                   (12) The Investor has not entered into any contracts,
         arrangements, understandings or relationships (written or otherwise)
         with any other Person or Persons (other than the Company or a limited
         partner/member or affiliate of Investor, which in any case shall not
         violate any securities laws) with respect to any securities of the
         Company (including but not limited to transfer or voting of any of the
         securities, finder's fees, joint ventures, loan or option arrangements,
         puts or calls, guarantees of profits, division of profits or loss, or
         the giving or withholding of proxies) or the operations, management or
         control of the Company; the Investor is not bound together, under
         common control with, in a common enterprise with, or otherwise acting
         in concert with, any other Person or Persons (other than a limited
         partner/member or affiliate of Investor, which in any case shall not
         violate any securities laws) in connection with the transactions
         contemplated by this Agreement; and the Investor does not own any
         securities of the Company which are pledged or otherwise subject to a
         contingency the occurrence of which would give another Person voting
         power or investment power over such securities.

                   (13) Except as otherwise set forth in ANNEX III, as of the
         date hereof, the Investor does not beneficially own any shares of
         Common Stock.

                   (14) No state, federal or foreign regulatory approvals,
         permits, licenses or consents or other contractual or legal obligations
         are required for the Investor to enter into this Agreement or otherwise
         purchase the Investor Shares.

                   (15) The Investor hereby covenants and agrees not to disclose
         any confidential information provided to the Investor by the Company in
         the Memorandum or otherwise in connection with the Private Placement
         with respect to the Company, except as otherwise required by law.

         (b) COMPANY REPRESENTATIONS, WARRANTIES AND COVENANTS. The Company
hereby represents, warrants and agrees as follows:

                   (1) The Company has been duly incorporated and is validly
         existing in good standing under the laws of the jurisdiction of its

         contemplated hereby have been duly authorized by all necessary action
         of the Company and the Agreement has been duly executed and delivered
         by the Company; and this Agreement,


                                       7



         when duly executed and delivered by the Investor, will constitute a
         valid and legally binding instrument of the Company enforceable in
         accordance with its terms.

                   (3) The Investor Shares have been duly authorized by the

         result in a breach or violation of any of the terms or provisions of,

         rule or regulation of any court or governmental agency or body having
         jurisdiction over the Company or any of its subsidiaries or any of
         their properties or assets other than a breach or violation that could
         reasonably be expected to have a material adverse effect on the
         condition (financial or otherwise), business, assets or results of
         operations of the Company (a "MATERIAL ADVERSE EFFECT"); and no
         consent, approval, authorization, order, registration or qualification
         of or with any such court or governmental agency or body is required
         for the valid authorization, execution, delivery and performance by the
         Company of this Agreement, the issue of the Investor Shares or the
         consummation by the Company of the other transactions contemplated by
         this Agreement, except for such consents, approvals, authorizations,
         registrations or qualifications as may be required under Federal or
         state securities or "blue sky" laws or, with respect to requirements
         applicable to the Investor and except where the failure to obtain such
         consents, approvals, authorizations, registrations or qualifications
         that could not reasonably be expected to have a Material Adverse
         Effect.

                   (5) The information contained in the following documents,
         which the Company has furnished to the Investor does not contain any
         untrue statement of material fact or omit to state any material fact
         necessary in order to make the statements therein in light of the
         circumstances in which they were made not misleading as of the
         respective final dates of the documents. Each of the documents listed
         in (A), (B) and (C) below complied as to form in all material respects

         5. REGISTRATION OF THE SHARES; COMPLIANCE WITH THE SECURITIES ACT.

              (a) REGISTRATION RIGHTS; REGISTRATION PROCEDURES AND EXPENSES.

                   (1) If at any time or times after the date hereof, the
         Company shall determine or be required to register any shares of its
         Common Stock or other equity securities for sale under the Securities
         Act in exchange for cash (whether in connection with a public offering
         of securities by the Company (a "PRIMARY OFFERING"), a public offering
         of securities by stockholders of the Company (a "SECONDARY OFFERING")
         or both), but not in connection with a registration effected solely to
         implement an employee benefit plan or a transaction to which Rule 145
         or any other similar rule of the Commission under the Securities Act is
         applicable, the Company shall:

                        (A) Promptly give written notice thereof to each of the
              Investors.

                        (B) Use commercially reasonable efforts to effect the
              registration under the Securities Act of all Investor Shares (but
              not any other shares) which such Investors request to be
              registered in a writing delivered to the Company within 10 days
              after such Investors' receipt of the notice referred to above,
              subject to subparagraph (iii) below.


                                        9



                        (C) In the case of the registration of shares of Common
              Stock by the Company in connection with an underwritten public
              offering, (a) the Company shall not be required to include any
              Investor Shares in such underwriting unless the Investors thereof
              accept the terms of the underwriting as agreed upon between the
              Company and the underwriter or underwriters selected by it, and
              (b) if the underwriter(s) determines that marketing factors
              require a limitation on the number of Investor Shares to be
              offered, the Company shall not be required to register Investor
              Shares of the Investors in excess of the amount, if any, of shares
              of the capital stock which the principal underwriter of such
              underwritten offering shall reasonably and in good faith agree to
              include in such offering in excess of any amount to be registered
              for the Company, and in the event of any such limitation, the
              number of Investor Shares of any Investor requesting inclusion in
              such registration shall be based upon the relative holdings of
              Common Stock of all Investors requesting such registration (and if
              any Investor would thus be entitled to include more Investor
              Shares than such Investor requested to be registered, the excess
              shall be allocated among other requesting Investors PRO RATA based
              upon their relative holdings of Common Stock). All expenses
              relating to the registration and offering of Investor
              Shares pursuant to this Section 5(a)(1) and pursuant to Section
              5(a)(2) below shall be borne by the Company, except that the
              Investors shall bear underwriting and selling commissions
              attributable to their Investor Shares being registered, any
              transfer taxes on shares being sold by such Investors and the
              costs of any counsel or other professional advisors engaged by the
              Investors.

Notwithstanding the foregoing, the Company's obligations pursuant to this
Section 5(a)(1) shall be suspended for so long as the Registration Statement
filed pursuant to Section 5(a)(2) is effective.

                   (2) The Company shall:

                        (A) Subject to the provisions of subparagraph (B) of
              this Section 5(a)(2) and Sections 5(c) and 5(d) below, use
              commercially reasonable efforts to prepare and file with the
              Commission within 30 days of the Closing a registration statement
              under Rule 415 under the Securities Act (the "REGISTRATION
              STATEMENT") to enable the public offering and sale of the Investor
              Shares by the Investor from time to time through the Nasdaq
              National Market, the over-the-counter market or in
              privately-negotiated transactions or otherwise.

                        (B) The Company shall use commercially reasonable
              efforts, subject to receipt of necessary information from the
              Investor, to cause the Registration Statement to become effective
              within 90 days after the Closing.

                        (C) Promptly prepare and file with the Commission such
              amendments and supplements to the Registration Statement and the
              prospectus used in connection therewith as may be necessary to
              keep the Registration Statement


                                       10



              effective for a period not exceeding the second anniversary of the
              Closing, or such shorter period which will terminate on the
              earlier of the date when (i) the Shares held by the Investor may
              be sold without registration under the Securities Act or (ii) all
              of the Shares covered by such Registration Statement have been
              sold pursuant to such Registration Statement or otherwise.

                        (D) Promptly furnish to the Investor with respect to the
              Investor Shares registered under the Registration Statement (and
              to each underwriter, if any, of such Investor Shares) such number
              of copies of the Registration Statement and any amendment or
              supplement thereto and of prospectuses and preliminary
              prospectuses in conformity with the requirements of the Securities
              Act as the Investor shall reasonably request.

                        (E) Promptly file documents required of the Company for
              customary "blue sky" clearance in states specified in writing by
              the Investor and reasonably required by the Investor in order to
              resell its Investor Shares; PROVIDED, HOWEVER, that the Company
              shall not be required to qualify to do business or consent to
              service of process in any jurisdiction in which it is not now so
              qualified or has not so consented.

                        (F) Promptly inform the Investor when any stop order by
              the Commission has been issued with respect to the Investor Shares
              and use commercially reasonable efforts to promptly cause such
              stop order to be withdrawn.

                        (G) Take such other actions as may reasonably be
              necessary to effect the registration of the resale of the Investor
              Shares in accordance with the terms of this Agreement and to allow
              such Investor Shares to trade in the same market system or
              exchange where the Company's Common Stock then trades.

                        (H) File the reports required to be filed by it under
              the Securities Act and the Exchange Act (or, if the Company is not
              required to file such reports, it will, upon the request of any
              holder of Investor Shares, make publicly available other
              information so long as necessary to permit sales under Rule 144
              under the Securities Act), all to the extent required from time to
              time to enable the Investor to sell Investor Shares without
              registration under the Securities Act within the limitations
              provided by (i) Rule 144 under the Securities Act, as such Rule
              may be amended from time to time, or (ii) any similar rule or
              regulation hereafter adopted by the Commission; PROVIDED,
              HOWEVER, that, except as otherwise expressly provided in this
              Section 5(a)(2)(H), nothing in this Agreement shall
              require the Company to file reports under the Securities Act or
              the Exchange Act, to register any of its securities under the
              Exchange Act, or to make publicly available any information
              concerning the Company at any time when it is not required by law
              or by any agreement by which it is bound to do any of the
              foregoing.


                                       11



A questionnaire related to the Registration Statement to be completed by the
Investor is attached hereto as ANNEX IV.

         (b) TRANSFER OF SHARES. The Investor agrees not to effect any
disposition of the Investor Shares or the right to purchase the Investor Shares
that would constitute a sale within the meaning of the Securities Act except as
contemplated in Sections 5(a)(1) and (2) or pursuant to an exemption from
registration under the Securities Act. The Investor agrees to promptly notify
the Company of any changes in the information set forth in any registration
statement regarding the Investor Shares or the Investor.

         (c) The Investor hereby acknowledges and agrees that in the event that
the Company makes any filing with the SEC in connection with a primary
underwritten offering within 30 days following the Closing Date, the time period
for preparing and filing a Registration Statement as contemplated by Section
5(a)(2) above shall be extended until May 31, 2002 and the Company shall use
commercially reasonable efforts, subject to the receipt of necessary information
from the Investor, to cause the Registration Statement to become effective as
promptly thereafter as practicable.

         (d) POSTPONEMENT. The Company may postpone the filing or effectiveness
of any registration statement to be filed pursuant to this Section 5 for a
reasonable period of time if (i) the Company is engaged in confidential
negotiations or other confidential business activities, disclosure of which
would be required in such registration statement and (ii) the Board of Directors
of the Company determines in good faith that such disclosure would have a
material adverse effect on any such confidential negotiations or other
confidential business activities or would be materially detrimental to the
Company.

         (e) INDEMNIFICATION AND CONTRIBUTION.

                   (1) For the purpose of this Section 5(e):

                        (A) The term "SELLING SHAREHOLDER" shall include the
              Investor, officers, directors, trustees, or any affiliate of such
              Investor and each person, if any, who controls the Selling
              Shareholder within the meaning of the Securities Act and

                        (B) The term "REGISTRATION STATEMENT" shall include (i)
              the Registration Statement and any final prospectus, exhibit,
              supplement or amendment included in or relating to the
              Registration Statement and (ii) any registration statement filed
              in connection with Section 5(a)(1) and any final prospectus,
              exhibit, supplement or amendment included in or relating to such
              registration statement; and

                   (2) The Company agrees to indemnify and hold harmless each
         Selling Shareholder from and against any losses, claims, damages or
         liabilities to which such Selling Shareholder may become subject (under
         the Securities Act or otherwise) insofar


                                       12



         as such losses, claims, damages or liabilities (or actions or
         proceedings in respect thereof) arise out of, or are based upon any
         untrue statement or alleged untrue statement of a material fact
         contained in the Registration Statement or the 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 arise out
         of any failure by the Company to fulfill any undertaking included in
         the Registration Statement and the Company will reimburse such Selling
         Shareholder for any reasonable legal or other expenses reasonably
         incurred in investigating, defending or preparing to defend any such
         action, proceeding or claim, PROVIDED, HOWEVER, that the Company shall
         not be liable in any such case to the extent that such loss, claim,
         damage or liability arises out of, or is based upon, any such untrue
         statement or omission made in such Registration Statement in reliance
         upon written information furnished to the Company by or on behalf of
         such Selling Shareholder for use in preparation of the Registration
         Statement, or the failure of such Selling Shareholder to comply with
         the covenants and agreements contained in Sections 4(a)(7) and 5(b)
         hereof respecting sale of the Shares or any statement or omission in
         any prospectus that is corrected or made not misleading in any
         subsequent prospectus that was delivered to the Investor prior to the
         pertinent sale or sales by the Investor. The Company will reimburse
         such Selling Shareholder, as the case may be, for any legal or other
         expenses reasonably incurred in investigating, defending or preparing
         to defend any such action, proceeding or claim.

                   (3) The Investor agrees to indemnify and hold harmless the
         Company (and each person, if any, who controls the Company within the
         meaning of Section 15 of the Securities Act, each officer of the
         Company who signs the Registration Statement and each director of the
         Company) from and against any losses, claims, damages or liabilities to
         which the Company (or any such officer, director or controlling person)
         may become subject (under the Securities Act or otherwise), insofar as
         such losses, claims, damages or liabilities (or actions or proceedings
         in respect thereof) arise out of, or are based upon, any failure to
         comply with the covenants and agreements contained in Sections 4(a)(7)
         and 5(b) hereof respecting sale of the Shares, or any untrue statement
         of a material fact contained in the Registration Statement on the
         effective date thereof if such untrue statement was made in reliance
         upon written information furnished by or on behalf of the Investor for
         use in preparation of the Registration Statement, PROVIDED, HOWEVER,
         that such Investor shall not be liable in any such case to the extent
         that the Investor has furnished in writing to the Company information
         expressly for use in such Registration Statement or any amendment
         thereof or supplement thereto which corrected or made not misleading
         information previously furnished to the Company prior to the filing of
         the Registration Statement, and if furnished to the Company after the
         filing of the Registration Statement, has notified the Company of such
         information immediately upon its occurrence or the Investor's knowledge
         of its occurrence. The Investor will reimburse the Company (or such
         officer, director or controlling person), as the case may be, for any
         legal or other expenses reasonably incurred in investigating, defending
         or preparing to defend any such action, proceeding or claim. In no
         event shall the liability of the Investor hereunder be greater in
         amount than the dollar amount of the proceeds received by such


                                       13



         Investor (net of any underwriting discount) upon the sale of the Shares
         giving rise to such indemnification obligation.

                   (4) Promptly after receipt by any indemnified person of a
         notice of a claim or the beginning of any action in respect of which
         indemnity is to be sought against an indemnifying person pursuant to
         this Section 5(e), such indemnified person shall notify the
         indemnifying person in writing of such claim or of the commencement of
         such action, and, subject to the provisions hereinafter stated, in case
         any such action shall be brought against an indemnified person and such
         indemnifying person shall be entitled to participate therein, and, to
         the extent it shall wish, to assume the defense thereof, with counsel
         reasonably satisfactory to such indemnified person. After notice from
         the indemnifying person to such indemnified person of its election to
         assume the defense thereof, such indemnifying person shall not be
         liable to such indemnified person for any legal expenses subsequently
         incurred by such indemnified person in connection with the defense
         thereof, PROVIDED, HOWEVER, that if there exists or shall exist a
         conflict of interest that would make it inappropriate, in the opinion
         of counsel to the indemnified person, for the same counsel to represent
         both the indemnified person and such indemnifying person or any
         affiliate or associate thereof, the indemnified person shall be
         entitled to retain its own counsel at the expense of such indemnifying
         person; PROVIDED, HOWEVER, that no indemnifying person shall be
         responsible for the fees and expenses of more than one separate counsel
         for all indemnified parties. The indemnifying party shall not be liable
         for any settlement of any proceeding effected without its written
         consent, but, if settled with such consent or if there be a final
         judgment for the plaintiff, the indemnifying party agrees to indemnify
         the indemnified party or parties in accordance with the provisions of
         this Section 5(e).

                   (5) If the indemnification provided for in this Section 5(e)
         from the indemnifying person is determined by a court of competent
         jurisdiction to be unavailable to an indemnified person hereunder in
         respect of any losses, claims, damages, liabilities or expenses
         referred to herein, then the indemnifying person, in lieu of
         indemnifying such indemnified person, shall contribute to the amount
         paid or payable by such indemnified person 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 person
         and indemnified persons in connection with the actions which resulted
         in such losses, claims, damages, liabilities or expenses, as well as
         any other relevant equitable considerations. The relative fault of such
         indemnifying person and indemnified persons shall be determined by
         reference to, among other things, whether any action in question,
         including any untrue or alleged untrue statement of a material fact,
         has been made by, or relates to information supplied by, such
         indemnifying person or indemnified persons, and the parties' relative
         intent, knowledge, access to information and opportunity to correct or
         prevent such action. 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, subject to the limitations set forth
         in this Section 5(e), any reasonable legal or other fees


                                       14



         or expenses reasonably incurred by such party in connection with any
         investigation or proceeding.

         The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(e) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(e), no Investor shall be
required to contribute any amount in excess of the dollar amount of the proceeds
received by such Investor (net of any underwriting discount) upon the sale of
the Shares giving rise to such contribution obligation. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
