investment purposes and reserves the right, in light of its ongoing evaluation
of the Issuer's financial condition, business, operations and prospects, the
market price of the Common Stock, conditions in the securities markets
generally, general economic and industry conditions, the Reporting Person's and
Issuer's respective business objectives, and other relevant factors, at any time
and as it deems appropriate, to change its plans and intentions, to increase or
decrease its investment in the Issuer, or to engage in discussions with the
Issuer and third parties or facilitate discussions between the Issuer and third
parties exploring such actions. In particular, any one or more of the Reporting
Persons may (i) purchase additional shares of Common Stock, (ii) sell or

continue to make such sales, in amounts that it may in its sole discretion
determine, which amounts, individually or in the aggregate, may be material, or
it may elect to discontinue or suspend such sales, without, in any case,
limiting the rights reserved in the immediately preceding paragraph or any other
rights of Starr International.

Stock, subject to rounding.

Trust Company (the "MRG/CPG Volaris Trustee").

         Under the MRG/CPG Trust Agreement, Mr. and Mrs. Greenberg agree to
transfer the MRG/CPG Trust Shares to the MRG/CPG Volaris Trustee, which is an
independent trustee that is unaffiliated with the Issuer, Mr. Greenberg or Mrs.
Greenberg. The MRG/CPG Volaris Trustee has sole power to vote and dispose of the
MRG/CPG Trust Shares. The MRG/CPG Trust Agreement instructs the MRG/CPG Volaris
Trustee to enter into an investment management agreement (the "MRG/CPG
Investment Management Agreement") with Credit Suisse Securities (USA) LLC as
investment manager for the trust whereby such investment manager will engage in

Trust is revocable, with respect to Mr. and Mrs. Greenberg's portion of this
Trust, upon written notice to the MRG/CPG Volaris Trustee by either Mr. or Mrs.
Greenberg, or completely revocable upon joint written notice to the MRG/CPG

or an agent under a power of attorney executed by such incapacitated person; or
if deceased, to the duly qualified legal representative of such deceased
person's estate, including the executors and/or administrators of such person's
estate.
