        The undersigned hereby constitutes and appoints Greg Henson, Robert
Wilson, T.J. Thom and Alan Townsend, or any of them acting without the other,
with full power of substitution, as the undersigned's true and lawful
attorney-in-fact to:

        (1)     execute for and on behalf of the undersigned (a) Forms 3, 4 and

and timely file such Forms or Schedules with the Securities and Exchange
Commission ("SEC") and any stock exchange, self-regulatory association or any
other authority;

        (3)     take any necessary or appropriate action to obtain or regenerate
codes and passwords enabling the undersigned to make electronic filings with the
SEC of reports required by Section 16(a) of the Act or any rule or regulation of
the SEC; and

        (4)     take any other action of any type whatsoever in connection with
the foregoing that, in the opinion of such attorney-in-fact, may be of benefit
to, in the best interest of, or legally required of the undersigned, it being

attorney-in-fact's discretion.

        The undersigned hereby grants to the attorney-in-fact full power and
authority to do and perform each and every act and thing whatsoever requisite,
necessary or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that the attorney-in-fact substitute, shall
lawfully do or cause to be done by virtue of this Power of Attorney and the
rights and powers herein granted. The undersigned acknowledges that the
foregoing attorney-in-fact, and its substitute, in serving in such capacity at
the request of the undersigned, is not assuming (nor is ROSE assuming) any of
the undersigned's responsibilities to comply with Section 16 of the Act.

        The undersigned agrees that the attorney-in-fact may rely entirely on
information furnished orally or in writing by the undersigned to the

ROSE and the attorney-in-fact against any losses, claims, damages or liabilities
(or actions in these respects) that arise out of or are based upon any untrue
statements or omissions of necessary facts in the information provided by the
undersigned to the attorney-in-fact for purposes of executing, acknowledging,
delivering or filing Form 3, 4 or 5, Form 144 or Schedule 13D or 13G (including
amendments thereto) and agrees to reimburse ROSE and the attorney-in-fact on
demand for any legal or other expenses reasonably incurred in connection with
investigating or defending against any such loss, claim, damage, liability or
action.

        This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5, Form 144 and
Schedules 13D and 13G (including amendments thereto) with respect to the
undersigned's holdings of and transactions in securities issued by ROSE unless
earlier revoked by the undersigned in a signed writing delivered to the
foregoing attorney-in-fact. This Power of Attorney does not revoke any other
power of attorney that the undersigned has previously granted.

                            [Signature page follows.]

        IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
be executed as of the date written below.
