Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	This is a joint filing by Desert Rock Enterprises LLC, a Nevada limited liability company ("Desert Rock"), the Derek J. Stevens Trust under agreement dated July 16, 1993 (the "Derek J. Stevens Trust"), Derek J. Stevens, as trustee of the Derek J. Stevens Trust, the Gregory J. Stevens Trust under agreement dated September 20, 1995 (the "Gregory J. Stevens Trust") and Gregory J. Stevens, as trustee of the Gregory J. Stevens Trust (collectively, the "Reporting Persons").
(2)	The Derek J. Stevens Trust directly owns 167,000 shares of Common Stock (the "Derek J. Stevens Trust Shares"). By virtue of Derek J. Stevens' position as the Manager of Desert Rock, and as trustee of the Derek J. Stevens Trust (which trust is also a member of Desert Rock), Derek J. Stevens may be deemed to have beneficial ownership of the Desert Rock Shares and/or the Derek J. Stevens Trust Shares.
(3)	The Gregory J. Stevens Trust directly owns 90,000 shares of Common Stock (the "Gregory J. Stevens Trust Shares"). By virtue of Gregory J. Stevens' position as the trustee of the Gregory J. Stevens Trust (which trust is also a member of Desert Rock), Gregory J. Stevens may be deemed to have beneficial ownership of the Desert Rock Shares and/or the Gregory J. Stevens Trust Shares.
(4)	Desert Rock is the designated filer. The Reporting Persons are filing this joint Form 4 because they may be regarded as part of a group. However, each Reporting Person disclaims beneficial ownership of the shares owned by the other Reporting Persons and disclaims membership in a group, and this filing shall not constitute an acknowledgement that the Reporting Persons are part of a group.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
