                                    AGREEMENT

         THIS AGREEMENT (this "Agreement") is made and entered into to be
effective as of the 12th day of August, 2002, by and between PEERLESS MFG. CO.
(the "Company"), and RICHARD L. TRAVIS, JR. ("Executive"), and amends in part
and restates and supersedes in its entirety that certain Agreement between the
Company and Executive dated February 4, 2002.

Executive has contributed substantially to the Company and wishes to offer an
inducement to Executive to remain in the employ of the Company;

         WHEREAS, the parties desire to enter into this Agreement to set forth
the benefits which the Company will pay to Executive in the event of a "Sale of
the Company" or termination of Executive's employment following a "Change in
Control" of the Company, except as a result of death, disability, voluntary
resignation or termination by the Company for Cause (in each case as such terms
or events are defined or discussed herein);

         NOW, THEREFORE, in consideration of the foregoing and of the respective
covenants and agreements of the parties herein contained the parties agree as
follows:

third anniversary of the occurrence of a Change in Control, (ii) Executive's
death, or (iii) Executive's earlier voluntary resignation (except for those
events described in Section 3(a)(2)); provided, however, that during the term of
this Agreement, on each anniversary of a Change in Control, the three year
period referenced in clause (i) above shall automatically be extended for an
additional 12 months unless, not later than 60 calendar days prior to such
anniversary date, the Company shall have given written notice to Executive that
it does not wish to have the term extended.

         (a)      Acquiring Person. An "Acquiring Person" shall mean any person
                  that, together with all Affiliates and Associates of such
                  person, is the beneficial owner of 15% or more of the

                  Common Stock of the Company for or pursuant to the terms of
                  any such plan, or Donald A. Sillers, Jr. or members of his

         (c)      Cause. For "Cause" shall mean any of the following shall have
                  occurred:

                  (i)      The conviction of Executive, by a court of competent
                           jurisdiction, of any felony;

                  (ii)     Commission by Executive of an intentional material
                           act of fraud to his pecuniary benefit in connection

                           with the Company, as reasonably determined by the

                           act, on the part of Executive shall be deemed
                           "intentional" unless done, or omitted to be done, by
                           Executive not in good faith and without reasonable
                           belief that his action or omission was in the best
                           interests of the Company.

                           under the Exchange Act) of securities which when

                  (v)      Any occurrence that would be required to be reported

                           discretion;

                  provided, however, a Change in Control of the Company shall
                  not be deemed to have occurred as the result of any

                  to Executive and the Company. Executive agrees to submit to
                  appropriate medical examinations and authorize his physicians
                  to release medical information necessary to determine whether

                  with a Sale of the Company. The value of any securities
                  (whether debt or equity) or other property shall be determined
                  as follows: (i) the value of securities that are freely
                  tradeable in an established public market will be determined
                  on the basis of the average closing market price on the last

                  closing of a Sale of the Company and (ii) the value of
                  securities that are not freely tradeable or have no
                  established public market and the

                  the Company no later than one business day prior to the
                  closing of a Sale of the Company. The Purchase Price will not

                           paid by the Company includable in gross income for
                           the five most recent full calendar years that
                           Executive has been an employee of the Company (or
                           such fewer full calendar years if Executive has been
                           an employee less than five full calendar years) prior
                           to the Change in Control; provided, however, that if
                           on the date of determination, Executive has not been
                           an employee of the Company for a full calendar year,

                           incentive compensation) annualized; and

                  (ii)     For a period of 36 months, provide Executive with

                                    thereafter significantly affecting his
                                    position, changes in the composition or
                                    policies of the Board, or of other events of

                                    of written notice from Executive of such
                                    determination;

                           (iii)    the relocation of the Company's principal
                                    executive offices, or the requirement by the
                                    Company that Executive have as his principal
                                    location of work any location not within the
                                    greater Dallas, Texas metropolitan area or
                                    that he travel away from his office in the
                                    course of discharging his duties hereunder
                                    significantly more (in terms of either
                                    consecutive days or aggregate days in any
                                    calendar year) than required of him prior to
                                    the Change in Control; or

                           (iv)     the Company commits any breach (including
                                    under Section 6 below) of this Agreement,
                                    which is not cured within ten calendar days
                                    after receipt by the Company of written
                                    notice from Executive of such breach.

         (b)      In the event that the total compensation paid to Executive as
                  severance in the event of a Change in Control, taking into
                  account all cash payments, shares of stock, accelerated
                  vesting of stock options, and bonuses, if any, is found to
                  constitute "an excess parachute payment" within the meaning of
                  Section 280G of the Code, then the Company will pay to
                  Executive, in addition to the Severance Compensation, an
                  additional amount which, after reduction for income taxes and
                  excise taxes on such additional amount, is sufficient to
                  provide for the payment of any excise tax that may be due by
                  Executive on the total compensation amount.

         (c)      Upon written notice given by Executive to the Company prior to
                  the receipt of Severance Compensation, Executive, at his sole
                  option, may elect to have all or any part of any such amount
                  paid to him, without interest, on an installment basis
                  selected by him.

         (d)      The payment of Severance Compensation by the Company to
                  Executive shall not affect any rights and benefits which
                  Executive may have pursuant to any other agreement, policy,
                  plan, program or arrangement with the Company prior to the
                  Termination Date, which rights shall be governed by the terms
                  thereof, except that payments hereunder after termination
                  shall reduce by an equal amount any sums payable after
                  termination of employment under the Employment Agreement,
                  dated February 4, 2002, by and between the Company and
                  Executive, as may be amended, restated or modified.

         (e)      The Company shall have no right of set-off or counterclaim in
                  respect of any claim, debt or obligation against any payment
                  or benefit to or for the benefit of Executive provided for in
                  this Agreement.

         (f)      Without limiting the rights of Executive at law or in equity,
                  if the Company fails to make any payment required to be made
                  hereunder on a timely basis, the Company shall pay interest on
                  the amount thereof on demand at an annualized rate of interest
                  equal to 120% of the then applicable Federal rate determined
                  under Section 1274(d) of the Code, compounded semi-annually
                  (but in no event shall such interest exceed the highest lawful
                  rate).

         (g)      If any of the events set forth in Section 3(a)(1) or 3(a)(2)
                  occurs prior to a Change in Control but following the
                  commencement of any discussion authorized by the Board with a
                  third person that ultimately results in a Change in Control
                  involving that person or a different third party, such event
                  shall be deemed to be a termination or removal of Executive
                  after a Change in Control for purposes of this Agreement and
                  shall entitle Executive to all benefits under this Agreement.

         4.       Sale Bonus.

         (a)      If a Sale of the Company occurs on or before July 1, 2003, in
                  addition to any other payments, bonuses or amounts that
                  Executive may be entitled to under any other agreements with
                  the Company, Executive will be entitled to a cash payment in
                  an amount equal to (i) the Purchase Price divided by the
                  number of issued and outstanding shares of capital stock of
                  the Company as of the closing of the Sale of the Company,
                  times (ii) 20,000, minus (iii) $260,000 (such amount being,
                  the "Sale Bonus"). The Sale Bonus will be subject to deduction
                  and withholding authorized or required by applicable law. The
                  Sale Bonus will be payable by the Company in full in cash at
                  the closing of a Sale of the Company. However, the Company
                  will have no obligation to pay Executive the Sale Bonus under
                  this Section 4 if (1) a Sale of the Company does not occur on
                  or before July 1, 2003, or (2) even though a Sale of the
                  Company occurs on or before July 1, 2003, prior to the closing
                  of the Sale of the Company, (x) Executive voluntarily
                  terminates his employment with the Company, dies or becomes
                  Disabled, (y) the Company terminates Executive for Cause, or
                  (z) Executive breaches any of the material terms of this
                  Agreement or the terms of the Employment Agreement, dated
                  February 4, 2002, by and between the Company and Executive.
                  The calculation of the Sale Bonus is based in part on the
                  number of issued and outstanding shares of the Company's
                  common stock (clause (ii)) as well as historical trading
                  prices of such shares (clause (iii)) as of the date hereof.
                  Clauses (ii) and/or (iii) of the calculation of the Sale Bonus
                  will be adjusted as is necessary to reflect the same economic
                  terms in the event of a stock dividend on, or a subdivision,
                  combination or reclassification of, the Company's common stock
                  after the date hereof, but will not be adjusted upon the
                  occurrence of any other dilutive event.

         (b)      In the event that the total compensation paid to Executive in
                  the event of a Sale of the Company, taking into account all
                  cash payments, shares of stock, accelerated vesting of stock
                  options, and bonuses, if any, is found to constitute "an
                  excess parachute payment" within the meaning of Section 280G
                  of the Code, then the Company will pay to Executive, in
                  addition to the compensation paid as the Sale Bonus, an
                  additional amount which, after reduction for income taxes and
                  excise taxes on such additional amount, is sufficient to
                  provide for the payment of any excise tax that may be due by
                  Executive on the total compensation amount received by
                  Executive.

         5. No Mitigation Required. In the event that this Agreement or the
employment of Executive hereunder is terminated, Executive shall not be
obligated to mitigate his damages nor the amount of any payment provided for in
this Agreement by seeking other employment or otherwise, and the acceptance of
employment elsewhere after termination shall in no way reduce the amount of
Severance Compensation payable hereunder.

         6. Successors; Binding Agreement.

         (a)      The Company will require any successor and any corporation or
                  other legal person which is in control of such successor (as
                  "control" is defined in Regulation 230.405 or any successor
                  rule or regulation promulgated under the Securities Act of
                  1933, as amended) to all or substantially all of the business
                  and/or assets of the Company (by purchase, merger,
                  consolidation or otherwise), by agreement in form and
                  substance reasonably satisfactory to Executive, to expressly
                  assume and agree to perform this Agreement in the same manner
                  and to the same extent that the Company would be required to
                  perform it if no such succession had taken place. Failure of
                  the Company to obtain such agreement prior to the
                  effectiveness of any such succession shall be a material
                  breach of this Agreement by the Company. Notwithstanding the
                  foregoing, any such assumption shall not, in any way, affect
                  or limit the liability of the Company under the terms of this
                  Agreement or release the Company from any obligation
                  hereunder. As used in this Agreement, "Company" shall mean the
                  Company as herein before defined and any successor to its
                  business and/or all or a substantial part of its assets as
                  aforesaid which executes and delivers the agreement provided
                  for in this Section 6 or which otherwise becomes bound by all
                  the terms and provisions of this Agreement by operation of
                  law.

         (b)      This Agreement and all rights of Executive hereunder shall
                  inure to the benefit of and be enforceable by Executive's
                  personal or legal representatives, executors, administrators,
                  successors, heirs, distributees, devisees and legatees.

         7. Notice. The Company shall give written notice to Executive within
ten days after any Change in Control. Failure to give such notice shall
constitute a material breach of this Agreement. For purposes of this Agreement,
notices and all other communications provided for in the Agreement shall be in
writing and shall be deemed to have been duly given when delivered or received
after being mailed by United States registered mail, return receipt requested,
postage prepaid, addressed as follows:

         If to Executive:

                  Dallas, Texas  75209

         If to the Company:

                  2819 Walnut Hill Lane
                  Dallas, Texas  75229
                  Attn:  Chairman of the Board

or to such other address as any party may have furnished to the other in writing
in accordance herewith, except that notices of change of address shall be
effective only upon receipt.



                                       8

         8. Miscellaneous. No provisions of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing signed by Executive and such officer as may be specifically
designated by the Board. No waiver by either party hereto of, or compliance
with, any condition or provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions
at the same or at any prior or subsequent time. No agreements or
representations, oral or otherwise, express or implied, unless specifically
referred to herein, with respect to the subject matter hereof have been made by
either party which are not set forth expressly in this Agreement.

         9. Validity. The invalidity or unenforceability of any provision or
provisions of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, which shall remain in full force and
effect.

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

         11. Employment Rights. Nothing expressed or implied in this Agreement
shall create any right or duty on the part of the Company or Executive to have
Executive remain in the employment of the Company prior to any Change in
Control.

         12. Withholding of Taxes. The Company may withhold from any amounts
payable under this Agreement all federal, state, city or other taxes as shall be
required pursuant to any law or government regulation or ruling.

         13. Enforcement Fees. All costs of litigation necessary for Executive
to defend the validity of this Agreement are to be paid by the Company or its
successors or assigns. The Company shall pay and be solely responsible for any
and all attorneys' and related fees and expenses incurred by Executive as a
result of the Company's failure to perform this Agreement or any provision
thereof or as a result of the Company or any person contesting the validity or
enforceability of this Agreement or any provision thereof as aforesaid.

         14. Rights and Remedies Cumulative. No right or remedy herein conferred
upon or reserved to Executive is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, including with
respect to Executive's rights under that certain Employment Agreement, dated
February 4, 2002, shall not prevent the concurrent assertion or employment of
any other appropriate right or remedy.

         15. Governing Law. This Agreement will be governed by and construed in
accordance with the internal laws of the State of Texas, without giving effect
to any conflicts of law rule or principle that might require the application of
the laws of another jurisdiction.



                                       9

         16. Disputes. The parties to this Agreement agree that in the event
there is a dispute or controversy between them that cannot be settled through
direct discussions, it is in the best interests of all for such dispute or
controversy to be resolved in the shortest time and with the lowest cost of
resolution as practicable. Consequently, any such dispute, controversy or claim
between the parties to this Agreement will not be litigated, but instead will be
resolved by arbitration in accordance with Title 9 of the U.S. Code (United
States Arbitration Act) and the Commercial Arbitration Rules of the American
Arbitration Association (the "Rules"), and judgment upon the award rendered by
the arbitrator may be entered in any court having jurisdiction thereof. The
arbitration will be before one neutral arbitrator and will proceed under the
Expedited Procedures of said Rules. The arbitration will be held in Dallas,
Texas, or such other place as may be selected by mutual agreement. The
arbitrator will have the discretion to order a prehearing exchange of
information by the parties, and to set limits for both the scope and time period
of such exchange. All issues regarding exchange requests will be decided by the
arbitrator. Neither party nor the arbitrator may disclose the existence, content
or results of any arbitration hereunder, unless required to do so by court or
regulatory order, without the prior written consent of both parties. Fees and
expenses of the arbitration itself will be borne by the parties equally;
provided, however, the arbitrator will also be authorized to award to the
prevailing party all or that fraction of its reasonable costs and fees as is
deemed equitable.
