      (3) No federal or state agency has made any finding or determination as to
the accuracy or adequacy of the Disclosure Materials or as to the fairness of
the terms of this Offering for investment nor any recommendation or endorsement
of the Securities.

      (4) The Offering is intended to be exempt from registration under the
Securities Act by virtue of Section 4(2) of the Securities Act and the
provisions of Regulation D thereunder, which is in part dependent upon the
truth, completeness, and accuracy of the statements made by the undersigned
herein and in the Questionnaire.

      (5) It is understood that in order not to jeopardize the Offering's exempt
status under Section 4(2) of the Securities Act and Regulation D, any transferee
will, at a minimum, be required to fulfill the investor suitability requirements
thereunder.

      (6) The Placement Agent will receive compensation in connection with the
Offering, but is not guaranteeing or assuming responsibility for the operation

readily accessible by publication (except as a result of a breach of this

purchase of the Securities.

      (9) Insofar as indemnification for liabilities under the Securities Act
may be permitted to directors, officers, or controlling persons of the Company,
the Company has been informed that, in the opinion of the Securities and
Exchange Commission, such indemnification is against public policy as expressed
in the Securities Act and is therefore unenforceable to such extent.

order to determine whether the undersigned PARTNERSHIP's subscription to
purchase the Securities described in the Subscription Booklet may be accepted.

      ALL INFORMATION CONTAINED IN THIS QUESTIONNAIRE WILL BE TREATED

Company may present this Questionnaire to such parties as it deems appropriate
if called upon to establish that the proposed offer and sale of the Securities
is exempt from registration under the Securities Act of 1933, as amended, or
meets the requirements of applicable state securities or "blue sky" laws.
Further, the undersigned PARTNERSHIP understands that the offering is required
to be reported to the Securities and Exchange Commission and to various state
securities and "blue sky" regulators.

I.    PLEASE CHECK ANY OF STATEMENTS 1-3 BELOW THAT APPLIES TO THE PARTNERSHIP.

      |_|   1.    The undersigned PARTNERSHIP: (a) has total assets in excess of

      IRA or Keogh retirement plan, alimony payments, and any amount by which
      income from long-term capital gains has been reduced in arriving at
      adjusted gross income.
