                  NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements contained herein, and intending to be legally
bound hereby, the parties hereby agree, severally and not jointly, as follows:

                  Section 1.  Voting of Shares. Until the termination of
this Agreement in accordance with the terms hereof, each Stockholder hereby
agrees that, at the Doubletree Stockholders' Meeting or any other meeting of the
stockholders of Doubletree, however called, and in any action by written consent
of the stockholders of Doubletree, such Stockholder will vote all of its
respective Shares (a) in favor of adoption of the Merger Agreement and approval
of the Doubletree Merger and the other transactions contemplated by the Merger
Agreement, and (b) in favor of any other matter necessary to the consummation of
the transactions contemplated by the Merger Agreement and considered and voted
upon by the stockholders of Doubletree (or any class thereof). In addition, each
Stockholder agrees that it will, upon request by Promus, furnish written
confirmation, in form and substance reasonably satisfactory to Promus, of such
Stockholder's support for the Merger Agreement and the Doubletree Merger. Each
Stockholder acknowledges receipt and review of a copy of the Merger Agreement.

                  Section 2.  Transfer of Shares. Each Stockholder
represents and warrants that it has no present intention of taking any action,
prior to the termination of this Agreement in accordance with the terms hereof,
to, directly or indirectly, (a) sell, assign, transfer (including by merger,
testamentary disposition, interspousal disposition pursuant to a domestic
relations proceeding or otherwise by operation of law), pledge, encumber or
otherwise dispose of any of its respective Shares, (b) deposit any of its
respective Shares into a voting trust or enter into a voting agreement or
arrangement with respect to any such Shares or grant any proxy or power of
attorney with respect thereto which is inconsistent with this Agreement or (c)
enter into any contract, option or other arrangement or undertaking with respect
to the direct or indirect sale, assignment, transfer (including by merger,
testamentary disposition, interspousal disposition pursuant to a domestic
relations proceeding or otherwise by operation of law) or other disposition of
any Shares.

                  Section 3. No Solicitation. Prior to the termination of
this Agreement in accordance with its terms, each Stockholder agrees (a) that it
will not, nor will it authorize or


                                       2
   3
permit any of its officers, directors, employees, agents and representatives to,
directly or indirectly, initiate or solicit any inquiries or the making of any
Acquisition Proposal and (b) that it will notify Promus as soon as possible (and
in any event within 48 hours) if any such inquiries or proposals are received
by, any information or documents is requested from, or any negotiations or
discussions are sought to be initiated or continued with, it or any of its
affiliates.

                  Section 4. Termination. This Agreement shall terminate
upon the earliest to occur of (i) the Effective Time or (ii) any termination of
the Merger Agreement in accordance with the terms thereof; provided that the
provisions of Section 7 shall survive any termination of this Agreement, and
provided further that no such termination shall relieve any party of liability
for a breach hereof prior to termination.

                  Section 5.  Registration Rights. Until the termination
of this Agreement in accordance with the terms hereof, no Stockholder will
exercise any of its rights to request or require registration of any securities
under the Incorporation and Registration Rights Agreement dated as of December
16, 1993, as amended on June 30, 1994, February 27, 1996 and November 8, 1996,
by and among Doubletree and certain stockholders of Doubletree (the
"Registration Rights Agreement).

                  Section 6. Specific Performance. The parties hereto
agree that irreparable damage would occur in the event any provision of this
Agreement was not performed in accordance with the terms hereof and that the
parties shall be entitled to specific performance of the terms hereof, in
addition to any other remedy at law or in equity.

                  Section 7. Miscellaneous.

                         (a) This Agreement constitutes the entire agreement
between the parties hereto with respect to the subject matter hereof and
supersedes all prior agreements and understandings, both written and oral,
between the parties with respect thereto. This Agreement may not be amended,
modified or rescinded except by an instrument in writing signed by each of the
parties hereto.

                         (b) If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any rule of law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible to the fullest extent
permitted by applicable law in a mutually acceptable manner in order that the
terms of this Agreement remain as originally contemplated to the fullest extent
possible.

                         (c) This Agreement shall be governed by and construed
in accordance with the laws of the State of Delaware without regard to the
principles of conflicts of law thereof.

                         (d) Notwithstanding anything herein to the contrary,
the covenants and agreements set forth herein shall not prevent any of the
Stockholders' designees, partners or

                                       3
   4
affiliates serving on the Board of Directors of Doubletree from taking any
action, subject to the applicable provisions of the Merger Agreement, while
acting in such capacity as a director of Doubletree.

                         (e). Notwithstanding any provisions hereof, none of the
obligations of any Stockholder under or contemplated by this Agreement shall be
an obligation of (i) any officer, director, stockholder, limited partner,
general partner or owner of such Stockholder, or any of their respective
officers, directors, stockholders, limited partners, general partners or owners,
or successors or assigns or (ii) any other Stockholder. Each Stockholder shall
be the only person or entity liable with respect to its obligations. Any
monetary liability of a Stockholder under this Agreement shall be satisfied
solely out of the assets of such Stockholder. Each Stockholder hereby
irrevocably waives any right it may have against any such officer, director,
stockholder, limited partner, general partner, owner, successor or assign
identified above as a result of the performance of the provisions under or
contemplated by this Agreement. Nothing in this Section 7(e) shall prevent
Promus from obtaining specific enforcement of the obligations of any Stockholder
under this Agreement.

                         (f) This Agreement may be executed in counterparts,
each of which shall be deemed an original and all of which together shall
constitute one and the same instrument.
