HEOF (INDIVIDUALLY, AN "INVESTOR") HEREBY REPRESENTS AND WARRANTS THAT:

5B.01 AUTHORIZATION. HEOF has full power and authority to enter into this
Agreement, and this Agreement constitutes its valid and legally binding
obligation, enforceable in accordance with its terms except (i) as limited by

participation in, or otherwise distributing the same. By executing this

transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration
under the Securities Act of 1933, as amended (the "Act"), only in certain
limited circumstances. In this connection, HEOF represents that it is

disposition of all or any portion of the Securities unless and until the
transferee has agreed in writing for the benefit of the Company to be bound
by this Section provided and to the extent this Section is then applicable,
and:

         (a) There is then in effect a Registration Statement under the Act
covering such proposed disposition and such disposition is made in accordance
with such Registration Statement; or

         (b) (i) HEOF shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition, and (ii) if
reasonably requested by the Company, HEOF shall have furnished the Company
with an opinion of counsel, reasonably satisfactory to the Company, that such
disposition will not require registration of such shares under the Act. It is
agreed that the Company will not require opinions of counsel for transactions
made pursuant to Rule 144 except in unusual circumstances.

5B.08 LEGENDS. It is understood that the certificates evidencing the HEOF
Securities will bear the following restrictive legend:

         "The shares represented by this certificate have been acquired for
investment and have not been registered under the Securities Act of 1933, as
amended, or the securities laws of any state. Except upon such registration,
such shares may not be sold or transferred at any time whatsoever except upon
delivery to the Company of an opinion of counsel satisfactory to the Company
that registration is not required for such transfer and/or submission to the
Company of such other evidence as may be satisfactory to the Company to the
effect that any such transfer shall not be in violation of the Securities Act
of 1933, as amended, and/or applicable state securities laws and/or any rule
or regulation promulgated thereunder."
