hereunder require registration or qualification with any governmental authority
under any federal or state law before such shares may be so issued, the Issuer
will in good faith use its reasonable best efforts as expeditiously as possible
at its expense to cause such shares to be duly registered or qualified.&#160; If the Issuer shall list any shares of Common
Stock on any securities exchange or market it will, at its expense, list thereon,
maintain and increase when necessary such listing, of, all shares of Warrant

securities exchange rules, all unissued shares of Warrant Stock which are at

the Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this

appropriate to protect the rights of the Holder hereof against dilution (to the

foregoing, the Issuer will (i) not permit the par value, if any, of its Common
Stock to exceed the then effective Warrant Price, (ii) not amend or modify any
provision of the Certificate of Incorporation or by-laws of the Issuer in any
manner that would adversely affect the rights of the Holders of the Warrants in

reasonably necessary in order that the Issuer may validly and legally issue
fully paid and nonassessable shares of Common Stock, free and clear of any
