     pursuant to Section 2.14 hereof may request that the Company file a
     registration statement on Form S-3 (or any successor form to Form S-3) for

     exceed $1,000,000, and provided further that the Company is a registrant
     entitled to use Form S-3 to register the Registrable Securities for such an
     offering. If TVG makes such a request, the Company shall use diligent
     efforts to cause such Registrable Securities to be registered for such
     offering on such form within sixty (60) days of TVG's request and to cause
     such Registrable Securities to be qualified in such jurisdictions as TVG
     may reasonably request; provided, however, that the Company shall not be
     required to effect more than one registration under this Section 2.6B. The
     substantive provisions of Section 2.4(b) shall be applicable to any
     registration initiated under this Section 2.6A.

          (b)  Notwithstanding the foregoing, the Company shall not be obligated
     to take any action pursuant to this Section 2.6B: (i) in any particular
     jurisdiction in which the Company would be required to execute a general
     consent to service of process in effecting such registration, qualification
     or compliance unless the Company is already subject to service in such
     jurisdiction and except as may be required by the Securities Act; (ii) if
     the Company, within ten (10) days of the receipt of TVG's request, gives
     notice of its bona fide intention to effect the filing of a registration
     statement with the Commission within ninety (90) days of receipt of such
     request (other than with respect to a registration statement relating to a
     Rule 145 transaction, an offering solely to employees or any other
     registration which is not appropriate for the registration of Registrable
     Securities); (iii) during the period starting with the date sixty (60) days
     prior to the Company's estimated date of filing of, and ending on the date
     six (6) months immediately following, the effective date of any
     registration statement pertaining to securities of the Company (other than
     a registration of securities in a Rule 145 transaction or with respect to
     an employee benefit plan), provided that the Company is actively employing
     in good faith all reasonable efforts to cause such registration statement
     to become effective; or (iv) if the Company shall furnish to TVG a
     certificate signed by the President of the Company stating that in the good
     faith judgment of the Board of Directors it would be seriously detrimental
     to the Company or its shareholders for registration statements to be filed
     in the near future, in which case the Company's obligation to file a
     registration

                                      -4-
<PAGE>

     statement shall be deferred for a period not to exceed one hundred twenty
     (120) days from the receipt of the request to file such registration by

     or amendment that affects a Purchaser in a manner or to an extent more
     adverse than any other Purchaser shall require the prior written consent of
