all Depositary Shares not owned by UAL, upon the terms and subject to the
conditions contained in a Prospectus dated November 20, 1996 and the
accompanying Letter of Transmittal (which together constitute the "Exchange
Offer") for its 13 1/4% Trust Originated Preferred Securities ("TOPrS").

and consulting services in connection with the Exchange Offer and requests and
authorizes Georgeson to contact, and to provide information with respect to the
Exchange Offer to, holders of the Depositary Shares. For this purpose,

additional services, the Trust agrees to pay Georgeson reasonable and customary
compensation, in an amount, if any, to be mutually agreed upon. The Trust
further agrees to reimburse Georgeson for, or pay directly where requested by
Georgeson, all reasonable and documented out-of-pocket expenses (including
counsel's fees and disbursements) incurred by Georgeson in retention hereunder,
provided that the travel expenses will not be reimbursed when travelling on an
air carrier other than United Airlines. The Trust agrees and acknowledges that

Offer.

approve any and all references to Georgeson in the Exchange Offer Materials.

respects, with the Securities Exchange Act of 1934, as amended, and the rules
and regulations of the Commission thereunder, and none of the Exchange Offer

including the applicable rules or regulations of any governmental or regulatory
authority or body, and no material consent or approval of, or filing with, any
government or regulatory authority or body is required in connection with the
making or consummation of the Exchange Offer (or, if any such material

by which the Trust is bound.

5. The Trust will advise Georgeson promptly of the occurrence of any
event which would cause it not to proceed with, or to withdraw or abandon the
Exchange Offer. The Trust will also advise Georgeson promptly of any proposal
or requirement to amend or supplement any of the Exchange Offer Materials.

6. The Trust hereby agrees to indemnify and hold harmless Georgeson,
Georgeson's controlling persons, officers, directors, employees, agents and
representatives (collectively, the "Indemnified Persons") from and against any
and all losses, claims, damages, liabilities and expenses whatsoever (including
but not limited to, all counsel fees, disbursements and other out-of-pocket
expenses) incurred by such Indemnified Persons in investigating, preparing to
defend or defending (or appearing or preparing for appearance as a witness in
connection with) any claim, litigation, proceeding, investigation, or
governmental or stock exchange inquiry, commenced or threatened or any claim
whatsoever; (i) arising out of or based upon any facts or circumstances
constituting a violation of, or in conflict with, any of the representations
and warranties set forth in Paragraph 4 above; or (ii) arising out of, relating
to or in connection with the Exchange Offer except for the Indemnified Person's
misconduct or negligence. The Trust shall reimburse such Indemnified Persons

foregoing indemnity shall be in addition to any liability which the Trust might
otherwise have to the Indemnified Persons.

7. Georgeson agrees to notify the Trust promptly of the assertion of any
claim against any of the Indemnified Persons in connection with the Exchange
Offer; and the Trust agrees to notify Georgeson promptly of the assertion of
any claim against the Trust or any of its officers, directors, employees or
agents in connection with the Exchange Offer. At the Trust's election, unless
there is a conflict of interest, the defense of the Indemnified Persons shall
be conducted by the Trust's counsel who shall be satisfactory to Georgeson and
the Indemnified Persons who are defendants in the action or proceeding.
Notwithstanding the Trust's election to assume the defense of such action or
proceeding, an Indemnified Person may employ separate counsel to represent it
or defend it in such action or proceeding and the Trust will pay the reasonable
fees and expenses of such counsel as set forth above if such Indemnified Person
reasonably determines that there are defenses available to such Indemnified
Person which are different from, or in addition to, those available to the
Trust, or if a conflict of interest exists which makes representation by
counsel chosen by the Trust not advisable; provided however, unless there are
actual or potential conflicts of interest among the Indemnified Persons, the
Trust will not be required to pay the fees and expenses of more than one
separate counsel for all Indemnified Persons in any jurisdiction in any single
action or proceeding. In any action or proceeding the defense of which the
Trust assumes, the Indemnified Persons shall nevertheless be entitled to
participate in such action or proceeding and retain its own counsel at such
Indemnified Person's own expense. The Trust shall not settle or compromise any
such consent, unless the terms of the settlement or compromise include an
unconditional release of any such Indemnified Person from all liability or loss
arising out os such action or proceeding.

8. The representations and warranties contained in paragraph 4 above and
the indemnity agreement contained in paragraphs 6 and 7 above shall remain
operative and in full force and effect regardless of: (i) the termination or
consummation of the Exchange Offer; and (ii) any investigation made by or on
behalf of any party.

9. This agreement shall be construed and enforced in accordance with the
laws of the State of New York. It is agreed that any action, suit or
proceeding arising out of or based upon this agreement shall be brought in the
United States District Court for the Southern District of New York or any court
of the State of New York of competent jurisdiction located in such District,
and the parties hereto hereby consent to the in personam jurisdiction

not been contained herein and shall be deemed an agreement between the parties
hereto to the fullest extent permitted by law.

If the foregoing correctly sets forth the understanding between the Trust
and Georgeson, please indicate acceptance thereof in the space provided below
