authority to enter into this Agreement and to perform all of its obligations
hereunder. The execution, delivery and performance of this Agreement by the
Company have been duly authorized by all necessary corporate actions, and this
Agreement constitutes a legal, valid, binding and enforceable obligation of the
Company. No consent, approval, authorization or order of any court or
governmental agency or board or any other third party, or registration,

                       (c) Investor acknowledges that it has been encouraged to
rely upon the advice of its legal counsel and accountants or other financial
advisers with respect to the financial, tax and other considerations relating to
the acquisition of the Shares and has been offered, during the course of

subject to substantial restrictions on resale or transfer.

                       (d) Investor agrees that it will not sell or otherwise
transfer or dispose of the Shares or any portion thereof unless such Shares are

offered and sold in reliance on specific exemptions or exclusions from the
registration requirements of federal and state laws and that the Company is
