            the course of his employment with the Company (and, if applicable,
            its predecessors), he has been allowed to become, and will continue
            to be allowed to become, acquainted with the business affairs,
            information, trade secrets, and other matters of the Company and its
            subsidiaries which are of a proprietary or confidential nature,

            is required by order of a court of competent jurisdiction (by
            subpoena or similar process) to disclose or discuss any Confidential
            Information, provided that in such case, Executive shall promptly

            becomes generally known to and available for use by the hotel and

            information. Executive further agrees that he will not during
            employment and/or at any time thereafter use such Confidential
            Information in competing, directly or indirectly, with the Company
            or any of its subsidiaries. At such time as Executive shall cease to
            be employed by the Company, he will immediately turn over to the
            Company all Confidential Information, including papers, documents,
            writings, electronically stored information, other property, and all
            copies of them provided to or created by him during the course of
            his employment with the Company.

                  (b) Heirs, successors, and legal representatives. The
                      --------------------------------------------
            foregoing provisions of this Paragraph 4 shall be binding upon
            Executive's heirs, successors, and legal representatives. The
            provisions of this Paragraph 4 shall survive the termination of this
            Agreement for any reason.

                  (c) Definition of Subsidiary. For purposes of this Paragraph 4
                      ------------------------
            and for purposes of Paragraph 5 (Covenant Not to Compete) below,

            promise to provide Confidential Information as set forth in
            Paragraph 4 above (including the Confidential Information provided
            by the Company to Executive concurrently with the execution of the
            Addendum, which Executive acknowledges has not been previously
            provided to Executive), and for Executive's employment by the
            Company under the terms provided in this Agreement, and as a means
            to aid in the performance and enforcement of the terms of and
            preserve the rights of the Company

            pursuant to the Unauthorized Disclosure provisions of Paragraph 4,
            Executive agrees as follows:

                        (a) during the term of Executive's employment with the
                  Company and for a period of twenty-four (24) months
                  thereafter, regardless of the reason for termination of
                  employment, Executive will not, directly or indirectly, as an
                  owner, director, principal, agent, officer, employee, partner,
                  consultant, servant, or otherwise, carry on, operate, manage,
                  control, or become involved in any manner with any business,
                  operation, corporation, partnership, association, agency, or
                  other person or entity which is in the business of owning,
                  operating, managing or granting franchise rights with respect
                  to hotels, motels or other lodging facilities in any area or
                  territory in which the Company or any of its subsidiaries
                  conducts operations; provided, however, that the foregoing
                  shall not prohibit Executive from owning up to one percent
                  (1%) of the outstanding stock of a publicly held company
                  engaged in the hospitality business. Notwithstanding the
                  foregoing, after Executive's employment with the Company has
                  terminated, upon receiving written permission by the Board,
                  Executive shall be permitted to engage in such activities with
                  respect to any other hotel, motel or lodging facility that
                  would be immaterial to the operations of the Company and its
                  subsidiaries in the area or territory in question.
                  Immateriality, for purposes of the foregoing sentence, shall
                  be determined in the sole discretion of the Board in good
                  faith.

                        (b) during the term of Executive's employment with the
                  Company and for a period of twenty-four (24) months
                  thereafter, regardless of the reason for termination of
                  employment, Executive will not, directly or indirectly, either
                  for himself or for any other business, operation, corporation,
                  partnership, association, agency, or other person or entity,
                  call upon, compete for, solicit, divert, or take away, or
                  attempt to divert or take away any of the customers
                  (including, without limitation, any hotel owner, lessor or
                  lessee, asset manager, trustee or consumer with whom the
                  Company or any of its subsidiaries from time to time (i) has
                  an existing agreement or business relationship; (ii) has had
                  an agreement or business relationship within the two-year
                  period preceding the Executive's last day of employment with
                  the Company; or (iii) has included as a prospect in its
                  applicable pipeline) or vendors of the Company or any of its
                  subsidiaries in any of the areas or territories in which the
                  Company or any of its subsidiaries conducts operations if such
                  action has the intent or effect of interfering with the
                  Company's or any of its subsidiaries' relationship with the
                  vendor or customer.

                        (c) during the term of Executive's employment with the
                  Company and for a period of twenty-four (24) months
                  thereafter, regardless of the reason for termination of
                  employment, Executive will not directly or indirectly solicit
                  or induce any current or prospective employee of the Company
                  or any of its subsidiaries (including, without limitation, any
                  current or prospective employee of the Company or any of its
                  subsidiaries within the six-month period preceding Executive's
                  last day of employment with the Company or within the 24-month
                  period of this covenant) to accept employment with Executive
                  or with any business, operation, corporation, partnership,
                  association, agency, or other person or entity with which
                  Executive may be associated, and Executive will not employ or
                  cause any business, operation, corporation, partnership,
                  association, agency, or other person or entity with which
                  Executive may be associated to employ any current or
                  prospective employee of the Company or any of its subsidiaries
                  without providing the Company with ten (10) days' prior
                  written notice of such proposed employment.

                        (d) Executive agrees and acknowledges that the
                  restrictions contained in this noncompetition covenant are
                  reasonable in scope of activity, duration and geographical
                  area and are necessary to protect the Company's business
                  interests and Confidential Information after the Effective
                  Date of this Agreement. If any provision of this
                  noncompetition covenant as applied to any party or to any
                  circumstance is adjudged by a court to be invalid or
                  unenforceable, the same will in no way affect any other
                  circumstance or the validity or enforceability of this
                  Agreement. If any such provision, or any part thereof, is held
                  to be unenforceable because of the duration of such provision
                  or the scope of activity or area covered thereby, the parties
                  agree that the court making such determination shall have the
                  power to reduce the duration and/or area and/or scope of
                  activity of such provision, and/or to delete specific words or
                  phrases, and in its reduced form, such provision shall then be
                  enforceable and shall be enforced. The parties agree and
                  acknowledge that the breach of this noncompetition covenant
                  will cause irreparable damage to the Company, and upon breach
                  of any provision of this noncompetition covenant, the Company
                  shall be entitled to injunctive relief, specific performance,
                  or other equitable relief; provided, however, that this shall
                  in no way limit any other remedies which the Company may have
                  (including, without limitation, the right to seek monetary
                  damages).

<PAGE>

                        (e) Should Executive violate the provisions of this
                  Paragraph, then in addition to all other rights and remedies
                  available to the Company at law or in equity, the duration of
                  this covenant shall automatically be extended for the period
                  of time from which Executive began such violation until he
                  permanently ceases such violation.

      4. Amendment to Subparagraph (6)(e). Termination by Executive. The last
         ----------------------------------------------------------
two sentences of Subparagraph 6(e) of the Employment Agreement are hereby
deleted in their entirety and replaced with the following:

                  "Good Reason Process" shall mean that (i) the Executive
            reasonably determines in good faith that a "Good Reason" event has
            occurred; (ii) Executive notifies the Company in writing (the "Good
            Reason Notice") of the occurrence of the Good Reason event; (iii)
            for a period (the "Good Reason Process Period") consisting of not
            less than thirty (30) days if the Good Reason Notice is delivered to
            the Company within 18 months after the occurrence of the first event
            constituting a Change in Control (as defined in Subparagraph 8(c))
            and not less than ninety (90) days in all other instances, Executive
            cooperates in good faith with the Company's efforts to modify
            Executive's employment situation in a manner acceptable to Executive
            and the Company; and (iv) notwithstanding such efforts, one or more
            of the Good Reason events continues to exist and has not been
            modified in a manner acceptable to Executive. If the Company cures
            the Good Reason event during the applicable Good Reason Process
            Period, Good Reason shall be deemed not to have occurred.

      5. Amendment to Subparagraph 7(d)(i). The last sentence of Subparagraph
         ---------------------------------
7(d)(i) of the Employment Agreement is hereby deleted in its entirety and
replaced with the following:

            Notwithstanding the foregoing, in the event Executive terminates his
            employment for Good Reason as provided in Subparagraph 6(e), he
            shall be entitled to the Severance Amount only if he provides the
            Good Reason Notice provided for in Subparagraph 6(e) within thirty
            (30) days after the occurrence of the event or events which
            constitute Good Reason as specified in clauses (A), (B), (C), (D),
            (E) and (F) of Subparagraph 6(e) and he provides the Notice of
            Termination provided for in Subparagraph 6(f) within five (5) days
            after the expiration of the Good Reason Process Period;

      6. Amendment to Paragraph 8. Change in Control Payment. In the last
         ----------------------------------------------------
sentence of the first paragraph of Paragraph 8 of the Employment Agreement, the
words "These provisions" are hereby deleted and replaced with "The provisions of
Subparagraph 8(a)".

      7. Amendments to Subparagraph 8(a). Change in Control. The first sentence
         --------------------------------------------------
of Subparagraph 8(a)(i) of the Employment Agreement is hereby deleted in its
entirety and replaced with the following:

            If within eighteen (18) months after the occurrence of the first
            event constituting a Change in Control, Executive's employment is
            terminated by the Company without Cause as provided in Subparagraph
            6(d) or Executive terminates his employment for Good Reason as
            provided in Subparagraph 6(e), then the Company shall pay Executive
            the Severance Amount as provided in Subparagraph 7(d)(i) in
            substantially equal bi-weekly installments, in arrears, over
            twenty-four (24) months; provided, however, that in the event
            Executive commences any employment with an employer other than the
            Company during such twenty-four (24) month period, the Company shall
            not be entitled to any right of set-off against the Severance Amount
            for any cash compensation received by the Executive from the new
            employer during such period.

            Subparagraph 8(a)(iii) is hereby deleted in its entirety and
replaced with the following:

                  (iii) Notwithstanding anything to the contrary in any
            applicable option agreement or stock-based award agreement, in the
            event of a Change in Control during the Period of Employment, any
            unvested portions of any stock option or other stock-based award
            shall fully vest and become exercisable one hundred eighty (180)
            days after the date of the Change in Control (provided Executive is
            employed by the Company on such 180th day) or, if earlier, on the
            date following the Change in Control that the Executive's employment
            with the Company is terminated by the Company without Cause or by
            the Executive for Good Reason. In the event of such termination,
            Executive shall have three hundred sixty (360) days following the
            Date of Termination to exercise all his stock options; provided,
            however, in no event may Executive exercise any stock option on or
            after the Expiration Date of such option (as defined in the
            applicable option agreement). With respect to a Change in Control
            occurring after the date of the Addendum, the foregoing provisions
            of this Subparagraph 8(a)(iii) are hereby substituted for and
            replace any provisions in any applicable option agreement relating
            to vesting in connection with a Change in Control or exercisability
            if Executive's employment is terminated without Cause or for Good
            Reason within 180 days after a Change in Control. Notwithstanding
            the first sentence of this Subparagraph 8(a)(iii), the Restricted
            Unit Award granted to Executive on April 12, 2001 shall not vest as
            provided in such first sentence and shall instead vest in accordance
            with the terms of such Restricted Unit Award. Executive shall also
            be entitled to any other rights and benefits with respect to
            stock-related awards, to the extent and upon the terms provided in
            the employee stock option or incentive plan or any agreement or
            other

            instrument attendant thereto (as amended hereby) pursuant to which
            such options or awards were granted; and

      8. Amendments to Subparagraph 8(b). Gross Up Payment. Subparagraph 8(b)(i)
         -------------------------------------------------
of the Employment Agreement is hereby deleted in its entirety and replaced with
the following:

                  (i) Excess Parachute Payment. If Executive incurs the tax (the
            "Excise Tax") imposed by Section 4999 of the Internal Revenue Code
            of 1986 (the "Code") on "excess parachute payments" within the
            meaning of Section 280G(b)(1) of the Code (whether such excess
            parachute payments arise out of this Agreement or otherwise), the
            Company will pay to Executive an amount such that the net amount
            retained by Executive, after deduction of any Excise Tax on the
            excess parachute payment and any federal, state and local income
            taxes and employment taxes (together with penalties and interest)
            and Excise Tax upon the payment provided for by this sentence, will
            be equal to the Severance Amount. In addition, if pursuant to the
            immediately preceding sentence a full gross up payment is not made
            to Executive for the entire amount of Excise Tax (and any federal,
            state and local income taxes and employment taxes (together with
            penalties and interest) and Excise Tax on the payment provided for
            in the immediately preceding sentence) incurred by Executive in
            connection with the first event constituting a Change in Control,
            then the Company will pay to Executive an additional amount that,
            after taking into account the amount payable pursuant to the
            immediately preceding sentence, will completely gross up the
            Executive for the entire amount of Excise Tax (and for any federal,
            state and local income taxes and employment taxes (together with
            penalties and interest) and Excise Tax on the payments provided for
            by this Subparagraph 8(b)(i)); provided, however, that any payment
            made pursuant to this sentence will not exceed an amount equal to
            twice the Executive's Base Salary or Adjusted Base Salary, as
            applicable, in effect immediately prior to the date of the Change in
            Control. The payments made pursuant to this Subparagraph 8(b)(i) are
            collectively referred to herein as the "Gross Up Payments". It is
            the intent that the Gross Up Payments provided for by this
            Subparagraph 8(b)(i) place Executive in the same position Executive
            would have been in had no Excise Tax been imposed, subject to the
            limitation on the Gross Up Payment provided for in the second
            sentence of this Subparagraph 8(b)(i) by the proviso of such
            sentence.

            Subparagraph 8(b)(ii) is hereby deleted in its entirety and replaced
with the following:

                  (ii) Applicable Rates. For purposes of determining the amount
            of the Gross Up Payments, Executive will be deemed to pay federal
            income taxes at the highest marginal rate of federal income taxation
            in the calendar year in which the Gross Up Payments are to be made
            and state and local income taxes at the highest marginal rates of
            taxation in the state and locality of Executive's primary


                                       7

            residence for the calendar year in which the Gross Up Payments are
            to be made, net of the maximum reduction in federal income taxes
            that could be obtained from deduction of such state and local taxes.

            Subparagraphs 8(b)(iii) and 8(b)(iv) are hereby deleted in their
entirety and are replaced with the following:

                  (iii) Time for Payment. The Company will pay the estimated
            amount of the Gross Up Payments in cash to Executive at such time or
            times when the Excise Tax is due. Executive and the Company and
            their respective tax advisors agree to confer and reasonably
            cooperate in the determination of the actual amount of the Gross Up
            Payments. Without limiting the foregoing, Executive shall, if
            requested by the Company, cooperate in a valuation of Executive's
            obligations under paragraph 5 of this Agreement by a valuation firm
            selected and paid for by the Company. Further, Executive and the
            Company agree to make such adjustments to the estimated amount of
            the Gross Up Payments as may be necessary to equal the actual amount
            of the Gross Up Payments, which in the case of Executive will refer
            to refunds of prior overpayments and in the case of the Company will
            refer to makeup of prior underpayments.

      9. Amendment to Subparagraph 8(c). Definitions. The penultimate sentence
         -------------------------------------------
of Subparagraph 8(c) is hereby deleted in its entirety and replaced with the
following:

            All defined terms used in the definition of "Change in Control"
            shall have the same meaning as set forth in the Certificate of
            Designation of Series B Convertible Preferred Stock of Wyndham
            International, Inc. as in effect on the Effective Date of this
            Agreement.

      10. Amendment to Paragraph 13. Arbitration; Other Disputes. Paragraph 13
          ------------------------------------------------------
of the Employment Agreement is hereby deleted in its entirety and replaced with
the following:

            13. Mediation and/or Arbitration; Other Disputes.
                --------------------------------------------

                  (a) General Procedures. In the event of any dispute or
                      ------------------
            controversy arising under or in connection with the terms of this
            Agreement, the parties shall first promptly try in good faith to
            settle such dispute or controversy by mediation under the Commercial
            Mediation Rules of the American Arbitration Association ("AAA")
            before resorting to arbitration, provided, however, that if the
            dispute or controversy concerns whether Executive is entitled to a
            payment under subparagraph 8(a) or 8(b) or the amount of any payment
            to which the Executive is entitled under subparagraph 8(a) or 8(b),
            the expedited procedures in subparagraph 13(b) will apply. In the
            event such dispute or controversy remains unresolved in whole or in
            part for a period of thirty (30) days after it is submitted to
            mediation, the parties will settle any remaining dispute or
            controversy exclusively by arbitration in Dallas, Texas in
            accordance with


                                       8

<PAGE>

            the Commercial Arbitration Rules of the AAA then in effect. The
            parties hereto agree that any dispute relating to the terms of this
            Agreement or the performance by the parties of their respective
            obligations under the terms of this Agreement shall not in any event
            be subject to the AAA's National Rules for the Resolution of
            Employment Disputes. Judgment may be entered on the arbitrator's
            award in any court having jurisdiction. With respect to a dispute or
            other controversy arising under or in connection with the terms of
            this Agreement after a Change in Control, all administration fees
            and arbitration fees shall be paid solely by the Company. Each party
            agrees to pay its own legal fees and expenses incurred in connection
            with mediation and/or arbitration.

                        Notwithstanding the above, the Company shall be entitled
            to seek a restraining order or injunction in any court of competent
            jurisdiction to prevent any continuation of any violation of
            paragraph 4 or 5 hereof. Should a dispute occur concerning
            Executive's mental or physical capacity as described in
            subparagraphs 6(b), 6(c) or 7(b), a doctor selected by Executive and
            a doctor selected by the Company shall be entitled to examine
            Executive. If the opinion of the Company's doctor and Executive's
            doctor conflict, the Company's doctor and Executive's doctor shall
            together agree upon a third doctor, whose opinion shall be binding.

                        Any amount to which Executive is entitled under this
            Agreement (including any disputed amount) which is not paid when due
            shall bear interest from the date due until paid at a rate equal to
            the lesser of eighteen percent (18%) per annum or the maximum lawful
            rate.

                  (b) Expedited Procedures. The following expedited procedures
                      --------------------
            apply in the event of any dispute or controversy concerning whether
            Executive is entitled to a payment under subparagraph 8(a) or 8(b)
            or the amount of any payment to which Executive is entitled under
            subparagraph 8(a) or (b), and are intended to supplement the general
            procedures detailed above. The parties shall first promptly try in
            good faith to settle such dispute or controversy by expedited
            mediation under the Commercial Mediation Rules of the AAA, as
            modified by this Agreement, before resorting to arbitration. In the
            event that such dispute or controversy remains unresolved in whole
            or in part for a period of fifteen (15) days after either party
            files a request for expedited mediation with the AAA, the parties
            will settle any remaining dispute or controversy exclusively by
            expedited arbitration in Dallas, Texas in accordance with the
            Expedited Procedures of the Commercial Arbitration Rules of the AAA
            then in effect, as modified by this Agreement. The parties agree
            that the arbitration hearing will be held sixty (60) days after the
            filing of a demand for expedited arbitration. The parties further
            agree that the following deadlines shall apply: (1) a party has
            fifteen (15) days following the


                                       9

<PAGE>

            conclusion of the mediation period to file an arbitration demand;
            (2) the opposing party then has seven (7) days to file an answering
            statement; (3) thereafter, the parties have thirty-five (35) days to
            conduct discovery, and (4) the parties have seven (7) days following
            the close of discovery to exchange copies of all exhibits that they
            intend to submit at the hearing. During the first five (5) days of
            the discovery period, and prior to either party starting discovery,
            the parties must agree upon the type of discovery that will be
            conducted and upon a discovery schedule. Any dispute regarding the
            type of discovery or the discovery schedule must be resolved by the
            arbitrator during a discovery conference conducted in person or on
            the telephone within the first five (5) days of the discovery
            period. The parties agree that the arbitrator shall have fifteen
            (15) days after the arbitration hearing to issue an award. The award
            shall be written and reasoned, if requested by one of the parties.

      11. Governing Law. The validity, interpretation, construction, and
          -------------
performance of this Addendum shall be governed by the laws of the State of Texas
(without regard to principles of conflicts of laws).

      12. Counterparts. This Addendum may be executed in several counterparts,
          ------------
each of which shall be deemed an original but all of which together will
constitute one and the same instrument.
