     We are opining herein as to the effect on the subject transaction only of
the internal laws of the State of Nevada and we express no opinion with respect
to the applicability thereto, or the effect thereon, of the laws of any other
jurisdiction.

     Subject to the foregoing and the other matters set forth herein, it is our
opinion that as of the date hereof each of the Guarantees to be executed and
delivered by each of the Covered Guarantors has been duly authorized by all
necessary corporate action of the respective Covered Guarantor, and when
executed and delivered in accordance with the terms of the Indenture and upon
due execution, authentication and delivery of the Securities and upon payment
therefor, each of the Guarantees will be the legally valid and binding
obligation of the respective Covered Guarantor, enforceable against the
respective Covered Guarantor in accordance with its terms.

     The opinions rendered in the foregoing paragraphs relating to the
enforceability of the Guarantees are subject to the following exceptions,
limitations and qualifications: (i) the effect of bankruptcy, insolvency,
reorganization, moratorium, fraudulent transfers, or other similar laws now or
hereafter in effect relating to or affecting the rights and remedies of
creditors; and (ii) the effect of general principles of equity, whether
enforcement is considered in a proceeding in equity or law, and the discretion
of the court before which any proceeding therefor may be brought.

     We express no opinion as to:

     (a) the unenforceability under certain circumstances under law or court
decisions of provisions for the indemnification of or contribution to a party
with respect to a liability where such indemnification or contribution is
contrary to public policy;

     (b) the enforceability of any provision requiring the payment of attorney's
fees, except to the extent that a court determines such fees to be reasonable;

     (c) the enforceability of provisions in the Operative Documents designating
New York as the governing law thereof;

     (d) the enforceability of any provision of the Operative Documents which
states that they (or any of them) may be modified or discharged only by a
subsequent agreement in writing;

     (e) the enforceability of, under certain circumstances, provisions in the
Operative Documents to the effect that failure to exercise, or delay in
exercising, rights or remedies will not operate as a waiver of such right or
remedy;

     (f) the enforceability of provisions of the Operative Documents requiring
that waivers must be in writing may not be enforceable if a non-executory oral
agreement has been created modifying any such provision or an implied agreement
by trade practice or course of conduct has given rise to a waiver; and

     (g) the securities or "blue sky" laws of the State of Nevada.

     We have not been requested to express, and with your knowledge and consent,
do not render any opinion as to the applicability to the obligations of the
Company under the Indenture and the Securities or the Guarantors under the
Indenture and the Guarantees of Section 548 of the United States Bankruptcy
Code.

     To the extent that the obligations of the Covered Guarantors under the
Guarantees may be dependent upon such matters, we assume for purposes of this
opinion that: (i) the Trustee and each Guarantor that is not a Covered Guarantor
(a) are duly organized, validly existing and in good standing under the laws of
its jurisdiction of organization; (b) have the requisite organizational and
legal power and authority to perform its obligations under each of the Operative
Documents to which it is a party; (c) are duly qualified to engage in the
activities contemplated by each such Operative Document; (d) have duly executed
and delivered each such Operative Document; and (e) have duly authorized each
such Operative Document; (ii) with respect to the Trustee and each Guarantor
that is not a Covered Guarantor, each Operative Document to which Trustee or any
such Guarantor is a party constitutes its legally valid and binding agreement,
enforceable against it in accordance with its terms; and (iii) the Trustee is in
compliance, generally and with respect to acting as a trustee under the
Indenture, with all applicable laws and regulations.

     This opinion is rendered only to you and the Security Holders and is solely
for your benefit and the benefit of the Security Holders in connection with the
transactions covered hereby. This opinion may not be relied upon by you or the
Security Holders for any other purpose, or furnished to, quoted to or relied
upon by any other person, firm or corporation for any purpose, without our prior
written consent. We have no responsibility or obligation to update this opinion,
to consider its applicability or correctness to any Person other than its
addressees, or to take into account changes in law, facts or any other
development of which we may later become aware.

     We consent to your filing this opinion as an exhibit to the Registration
Statement.



                                Very truly yours,

                                /s/ Hale Lane Peek Dennison and Howard
