ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS
         ------------------------------------

         Pursuant to an agreement among (i) Refrigeration Technology Inc.
("RefTech"), a newly-formed Delaware corporation wholly-owned by RTI Inc. (the
"Company"), (ii) Quality Air, Inc., a New Mexico corporation ("QAI"), (iii) Rick
E. Bacchus, Rockney D. Bacchus and Ron Bacchus, the principal officers of QAI
(the "Officers"), and (iv) Margie J. Bacchus, Philis Bacchus and Opal Simmons,
the principal owners of QAI ( the "Owners"), dated February 24, 1997 (the
"Acquisition Agreement"), among other things, QAI sold its business and
substantially all of its assets to RefTech (the "Transaction"). Prior to the
Transaction, QAI was a manufacturer of high-efficiency residential air coolers
and central air conditioners, manufactured in Sunland Park, New Mexico and,
through an affiliated Mexican company, Industrias QAI, S.A. de C.V. ("Industrias
QAI"), in Ciudad Juarez, Mexico. The Company, through RefTech, intends to
continue the acquired business.

         In accordance with the Transaction, which was consummated on February
24, 1997 (the "Closing"), RefTech delivered to QAI 235,000 shares of the
Company's common stock, par value $.08 per share ("Common Stock"), 50,000 shares
of which are being held in escrow for purposes of covering claims of RefTech
which may arise under the indemnification provisions of the Acquisition
Agreement. In addition, RefTech agreed to deliver to QAI (i) an additional
100,000 shares of Common Stock, if and when the Company's pre-tax fiscal year
earnings from operations exceed $800,000, and (ii) an additional 125,000 shares
of Common Stock, if and when such earnings exceed $1,200,000; provided, however,
that such events occur prior to January 1, 2002.

         As part of the Transaction, RefTech acquired substantially all of the
assets of QAI, the tangible assets of which, as of January 31, 1997 (unaudited),
consisted primarily of approximately (i) $302,000 of inventory (a portion of
which was at Industrias QAI), (ii) $159,000 (net of accumulated depreciation and
amortization) of furniture, equipment and vehicles, (iii) $223,000 of loans to,
and receivables from, Industrias QAI, (iv) $268,000 of third party receivables,
and (v) $45,000 of cash. In addition, RefTech acquired all of the intangible
assets of QAI, including a patent application of one


                                        2

<PAGE>



of the  Officers  which had been  assigned to QAI. In the  Transaction,  RefTech
assumed  certain  specified   liabilities  of  QAI,   consisting  of  QAI's  (i)
indebtedness to the Company  aggregating  $670,000 plus accrued interest,  which
was  incurred  by QAI prior to its  December  1996  letter  of  intent  with the
Company,  (ii)  indebtedness  to Theo W.  Muller,  chief  executive  officer and
Chairman of the Company, and his affiliated companies  aggregating $830,000 plus
accrued  interest,  $780,000  of which was  incurred  by QAI  subsequent  to its
December 1996 letter of intent with the Company,  (iii) QAI purchase commitments
incurred in the ordinary course of QAI's business for inventories,  supplies and
services  aggregating  approximately  $1,300,000,  and (iv) other QAI  scheduled
liabilities  incurred  in the  ordinary  course  of QAI's  business  aggregating
approximately $45,000.

         It is anticipated that QAI will promptly liquidate and distribute its
remaining assets (including its shares of Common Stock and its contingent rights
to receive additional shares of Common Stock) to the shareholders of QAI.

         The Acquisition Agreement provides that, during the period through
December 31, 2001, the Officers, as a group, are to have the non-assignable
right to nominate three of the seven directors constituting the Company's Board
of Directors.

         Prior to the Closing, the Company amended its By-Laws to provide that
the Company's Chairman (currently Theo W. Muller) is to be the Company's Chief
Executive Officer. Effective at the Closing, (i) the Company elected Rick E.
Bacchus as President of the Company and Rockney D. Bacchus and Ron Bacchus as
Vice Presidents of the Company, and (ii) each of the Officers entered into
five-year employment agreements with RefTech (the "Employment Agreements"),
pursuant to which Rick E. Bacchus was appointed President of RefTech (reporting
to RefTech's Chairman and Chief Executive Officer, currently Theo W. Muller),
Rockney D. Bacchus was appointed Vice President - Development of RefTech and Ron
Bacchus was appointed Vice President - Manufacturing of RefTech. The Employment
Agreements each provide that the employee is to receive annual base compensation
of $80,000 and may be terminated without cause upon payment of two months'
salary.


                                        3

         RefTech has agreed to lend up to an aggregate of $240,000 to the
Officers, repayable with interest at 1% over prime during the period ending
December 31, 2001. RefTech (i) has the right to purchase from Bacchus
Industries, an affiliate of the Owners and the Officers, equipment and vehicles
which had been leased to QAI, for an amount equal to their fair market value,
and (ii) has agreed to lease from Bacchus Industries the factory building in
Sunland Park, New Mexico, which had been occupied by QAI, for a three-year
period at a net rental of the lesser of (a) $6,500 per month, or (b) the
payments due the Small Business Administration (the "SBA") under a loan between
the SBA and the landlord.

         In contemplation of, as an integral part of, the Transaction, on
February 19, 1997, RefTech entered into a sale and purchase agreement with
Industrias QAI and its two shareholders, Opal Simmons and Robert Given (the
"Industrias QAI Agreement"), pursuant to which RefTech was given the right to
acquire either the capital stock of Industrias QAI or the business and assets of
Industrias QAI, at its election at any time within sixty days after February 19,
1997. RefTech paid no additional consideration for its rights under the
Industrias QAI Agreement. The purchase price to be paid upon closing of the
Industrias QAI Agreement will be the higher of the book value of the capital
stock of Industrias QAI (which had a deficit book value (unaudited) of
approximately $12,000 as of January 31, 1997) or 1,000 Mexican pesos. RefTech
has been granted the sole authority to manage Industrias QAI, whose only
customer has been QAI, until such closing.

         The foregoing information with respect to the Transaction is qualified
in its entirety by the complete text of the Acquisition Agreement and the other
agreements referred to therein, copies of which are filed as exhibits hereto and
are incorporated herein by reference.

Shares,  if and when the pre-tax earnings of RTI for any subsequent  fiscal year

accountants delivered to RefTech, RTI and the Principals, and (b) shall be final
and binding on all parties.  Certificates  evidencing any Earn-Out  Shares to be

receipt of the accountants' determination that Earn-Out Shares have been earned.
Such  certificates  shall be  delivered to the Escrow  Agent,  unless the Escrow
Agreement has been terminated.

power and authority (when  authorized by requisite  corporate  actions) to sell,
transfer, assign, convey and liquidate all of its assets and properties, without

submission  thereof  to a vote  of such  shareholders;  thereafter,  (i)  notice
thereof was given to each  shareholder of record of QAI, (ii) such  transactions
were duly authorized by the  shareholders of QAI, and (iii) neither at nor prior
to the time of such due authorization did any shareholder of QAI file with QAI a
written  objection  to  the  proposed  corporate  action.  In  addition  to  the
foregoing,  QAI has taken all other necessary  corporate action to authorize the
execution,  delivery and  performance of this Agreement and the  consummation of

performance of this Agreement by QAI and the Principals, and the consummation of
the transactions contemplated hereby shall not, with or without the giving

Exchange  provided  for in this  Agreement,  and the issuance of the RTI Shares,
will be exempt from  registration  under the Securities Act, pursuant to Section

that it considers  necessary or appropriate  for deciding  whether to effect the

pursuant to an applicable  exemption from registration under the Securities Act.
QAI and the Principals  acknowledge that, pursuant to Rule 144 promulgated under

               9.3 POST  CLOSING  MANAGEMENT  OF  REFTECH.  During the  Earn-Out
Period,  Rick E. Bacchus,  Rockney D. Bacchus and Ron Bacchus, as a group, shall
have  the  non-assignable  right  to  nominate  three  of  the  seven  directors
constituting RTI's Board of Directors. RTI covenants and agrees that, subject to
its fiduciary duties, as the sole stockholder of RefTech,  it will encourage the
directors of RefTech to elect Rick E. Bacchus as its  President,  and to elect a
chief financial officer who shall be recommended by Theo W. Muller as long as he
is the chief executive officer of RTI.

               9.4  REORGANIZATION  TREATMENT.  RefTech  and QAI shall  take all
actions necessary to cause the Exchange and the other transactions  contemplated
by this Agreement to be treated for tax purposes as a reorganization  under Code
Section  368(a)(1)(C),  including  all  actions  necessary  to  comply  with the
"continuity of business  enterprise" and  "continuity of interest"  requirements
with respect thereto.

         X.    INDEMNIFICATION
               ---------------

               10.1 BY QAI AND THE  PRINCIPALS.  After the Closing,  QAI and the
Principals  agree to jointly and  severally  indemnify  and hold RefTech and RTI
harmless  against  and in  respect  of any and all  loss,  liability  or  damage
incurred or sustained by RefTech or RTI in connection with any breach by (i) the
Company or the Principals of any provision of this Agreement, including, without
limitation, any breach of any representations,  warranties and covenants made by
any of them herein,  and (ii) by the Affiliate or any of its stockholders of any
provision of the Affiliate Documents,  including, without limitation, any breach
of any representations, warranties and covenants made by any of them therein, in
each case  including,  subject to the provisions of Section 10.3, all reasonable
costs and expenses  (including  reasonable  attorneys' fees) incurred by RefTech
and RTI in connection with any action, suit, proceeding,  demand,  assessment or
judgment incident to any such matter.

               10.2 BY REFTECH.  After the Closing,  RefTech agrees to indemnify
and hold QAI and the Principals  harmless  against and in respect of any and all
loss,  liability or damage  incurred or sustained by QAI in connection  with any
breach  by  RefTech  of any  provision  of this  Agreement,  including,  without
limitation, any breach of any representations,  warranties and covenants made by
RefTech  herein,  including,  subject to the  provisions  of Section  10.3,  all
reasonable costs and expenses (including reasonable attorneys' fees) incurred by
QAI or the Principals in connection with any action, suit,  proceeding,  demand,
assessment or judgment incident to any such matter.

               10.3  NOTICES,   DEFENSE,   ETC.  Promptly  upon  receipt  by  an
indemnified  party of notice of any claim or the  commencement of any action for
which indemnity may be sought hereunder, the indemnified party (i) if RefTech or
RTI,  shall  notify  Rick E.  Bacchus  or his  nominee,  and  (ii) if QAI or the
Principals,  shall  notify RTI, in writing of the claim or the  commencement  of
such action,  attaching to such notice a copy of the claim or judicial  pleading
received. The indemnifying party shall be entitled to participate in the defense
of any such claim or action that may be brought  against an  indemnified  party,
and may elect,  by notice to the  indemnified  party  within a  reasonable  time
following  notification by the indemnified  party, to assume the defense thereof
with counsel reasonably satisfactory to the indemnified party, and to settle and
compromise any such claim or action; provided,  however, that if the indemnified
party has elected to be represented by separate  counsel pursuant to the proviso
to the following sentence,  such settlement or compromise shall be effected only
with  the  consent  of  the  indemnified  party,  which  consent  shall  not  be
unreasonably   withheld,   delayed  or   conditioned.   After  notice  from  the
indemnifying  party to the  indemnified  party of its  election  to  assume  the
defense of such claim or action,  the indemnifying  party shall not be liable to
the indemnified party for any legal or other expenses  subsequently  incurred by
the  indemnified  party  in  connection  with the  defense  thereof  other  than
reasonable costs of investigation; provided, however, that the indemnified party
shall have the right to employ  counsel to represent  it if, in the  indemnified
party's sole reasonable  judgment,  it is advisable for the indemnified party to
be  represented  by separate  counsel due to a conflict of interest and, in that
event,  the  reasonable  fees  and  expenses  of  such  separate  counsel  shall
thereafter  be paid by the  indemnifying  party.  The parties agree to render to
each other such assistance as may reasonably be requested in order to insure the
proper and adequate defense of any such claim or action.

               10.4 RECOURSE  AGAINST QAI AND THE PRINCIPALS.  In the event that
RefTech or RTI shall be entitled to indemnification as provided in this Article,
upon the determination thereof it shall give Rick E. Bacchus or his


                                      -18-

<PAGE>



nominee notice thereof.  Unless RefTech shall have received  payment in the full
amount of the indemnified claim within thirty days of its giving such notice, it
shall give notice to the Escrow Agent that it is entitled to indemnification, in
which event the Escrow Agent shall cause to be redelivered to RefTech or to RTI,
out of the RTI Shares  held in escrow  pursuant  to the Escrow  Agreement,  such
number of RTI shares as when  multiplied  by their  market  value per share,  as
herein determined,  equals the amount of the unreimbursed indemnified claim. For
the purposes of this Section,  "market value" means the average closing price of
the Common  Stock as quoted on NASDAQ or any  national  securities  exchange  on
which  the  Common  Stock  may then be  traded  during  the  thirty  day  period
immediately prior to delivery of such notice to the Escrow Agent, and if at such
time the  Common  Stock is not so traded  then at the most  recent  ask price as
quoted by the National  Quotation  Bureau,  Inc. (or any successor  organization
performing a similar reporting  function).  If the RTI Shares held by the Escrow
Agent shall be insufficient to reimburse RefTech in full, QAI and the Principals
shall be jointly and severally responsible for the balance.

         XI.   TERMINATION
               -----------

               11.1   TERMINATION.   This   Agreement   and   the   transactions
contemplated  herein may be  terminated at or prior to the Closing (i) by mutual
consent of RefTech and QAI, or (ii) by RefTech  pursuant to notice  delivered at
or prior to the Closing if the Company or the  Principals  fail in any  material
respect to satisfy all of the conditions to the Closing to be satisfied by them.

         XII.  Miscellaneous
               -------------

               12.1  FURTHER  ASSURANCES.  The  parties  shall do and perform or

and  accomplish  the  purposes of this  Agreement  and the  consummation  of the

               12.2  FINDERS'  FEES.  Each of the  parties  (i)  represents  and
warrants that,  except as set forth on Schedule 12.2, it has not taken and shall
not take any action which would cause the other  parties to have any  obligation
or  liability  to  any  person  for  finders'  fees,   brokerage  fees,  agents'
commissions  or like payments in  connection  with the execution and delivery of
this Agreement or the consummation of the transactions  contemplated hereby, and
(ii)  agrees to  indemnify  and hold the other  parties  harmless  for any loss,
liability,  cost or expense  (including,  without  limitation,  legal  expenses)
arising out of the breach or  inaccuracy  of the  foregoing  representation  and
warranty.

               12.3 EXPENSES.  Whether or not the  transactions  contemplated by
this Agreement are  consummated,  the parties shall pay the fees and expenses of
their respective counsel,  accountants and other experts, and all other expenses
incurred by such party  incident  to the  negotiation,  preparation,  execution,
delivery and  performance  of this Agreement and the  transactions  contemplated
hereby;  provided,  however, that if this Agreement is terminated because of any
party's breach of this  Agreement,  such party shall remain liable in damages to
the other party to this Agreement.

               12.4   SURVIVAL   OF   REPRESENTATIONS   AND   WARRANTIES.    The
representations,   warranties,   covenants  and  agreements  contained  in  this
Agreement or in any instrument or document delivered or to be delivered pursuant
to  this  Agreement  shall  survive  the  Closing  and the  consummation  of the
transactions contemplated hereby,  notwithstanding any investigation at any time
made by or on behalf of any party or parties hereto.

               12.5  ARBITRATION.  Any  controversy  or claim  arising out of or
relating to this Agreement or the breach of any term or provision  thereof shall
be  settled  by  arbitration  in  accordance  with  the  Rules  of the  American
Arbitration  Association  and judgment upon the award rendered by the Arbitrator
or  Arbitrators  may be entered in any Court having  jurisdiction.  In the event
that the parties to the  controversy  or claim can not agree on the  location of
the arbitration, the arbitration shall be conducted in New York City, New York.

                                                                       EXHIBIT 2

                  ESCROW AGREEMENT (this  "Agreement")  dated as of February --,
1997,  by and  among  Refrigeration  Technology  Inc.,  a  Delaware  corporation
("RefTech"),  Quality Air,  Inc., a New Mexico  corporation  ("QAI"),  Margie J.
Bacchus,  Philis Bacchus,  Rick E. Bacchus,  Rockney D. Bacchus, Ron Bacchus and
Opal Simmons (each a "Principal" and collectively,  the  "Principals"),  and the
Escrow Agent named herein.

                                    Recitals
                                    --------

                  RefTech,   QAI  and  the  Principals   have  entered  into  an
         Acquisition  Agreement,  dated as of the date hereof (the  "Acquisition
         Agreement"),  which  provides  for the  acquisition  by  RefTech of the
         business and substantially all of the assets of QAI.  Capitalized terms
         used in this  Agreement,  and not otherwise  defined  herein,  have the
         meanings defined in the Acquisition  Agreement.  It is the intention of
         the parties  that if the Closing does not take place,  this  Agreement,
         and  all  obligations  and  rights  of  each  party  hereunder,   shall
         immediately terminate as if this Agreement had never been entered into.

                  The Acquisition  Agreement  provides that (i) 50,000 shares of
         Common  Stock,  which  are  part  of  the  Exchange  Consideration,  be
         deposited in escrow at the Closing under this  Agreement,  and (ii) any
         Earn-Out Shares subsequently delivered by RefTech after the Closing, if
         delivered  prior to the time that this Agreement has been terminated in
         accordance  with its terms,  likewise be deposited in escrow under this
         Agreement (all such shares so deposited being the "Escrow Shares"),  to
         secure  certain  obligations  of  QAI  and  the  Principals  under  the
         Acquisition  Agreement,  on the terms and  conditions set forth therein
         and herein.  The Escrow Shares,  together with all stock powers related
         thereto, are collectively the "Escrow Deposit".

                  The   Acquisition   Agreement   provides   for  the   complete
         liquidation of QAI and the  distribution  of its assets,  including its
         interest in the Escrow Shares, to certain or all of the Principals (the
         "Liquidation").

                  The  parties  desire to  establish  the  terms and  conditions
         pursuant to which the Escrow  Deposit will be held and disbursed by the
         Escrow Agent.

                  NOW,  THEREFORE,  in  consideration  of  the  premises  and in
reliance upon the mutual representations,  warranties,  covenants and agreements
hereinafter set forth, the parties agree as follows:

                  1.  ADMINISTRATION.  For the purposes of this  Agreement,  the
Principals  have agreed that the Notice Agent shall  represent them and QAI, and
that they and QAI shall be  irrevocably  bound by any action of, or notice given
by, the Notice Agent. QAI and the Principals hereby initially  designate Rick E.
Bacchus as the "Notice Agent".  The Notice Agent shall have the right to appoint
a  substitute  Notice  Agent,  on notice to each of the  other  parties  to this
Agreement.  The  Principals  shall have the right to replace the Notice Agent by
giving like notice signed by all of the Principals.

                  2.   ESCROW.

                  2.1  ESCROW.  The  Escrow  Deposit  will be held in  escrow by
Warshaw  Burstein  Cohen  Schlesinger & Kuh, LLP (the "Escrow  Agent"),  with an
office at 555 Fifth Avenue,  New York,  New York 10017,  as  collateral  for the
obligations  of QAI  and  the  Principals  under  Article  X of the  Acquisition
Agreement,  subject only to release pursuant to the terms of this Agreement. The
Escrow



<PAGE>

Agent agrees to accept  delivery of the Escrow  Deposit,  and to hold the Escrow
Deposit in escrow subject to the terms and conditions of this Agreement.

                  2.2 DELIVERY AT THE CLOSING. At the Closing, the Escrow Shares
being  delivered at the Closing  will be  delivered by QAI to the Escrow  Agent,
together with a stock power duly executed in blank by QAI, sufficient in form to
permit the transfer of the Escrow Shares upon delivery.

                  2.3  LIQUIDATION  OF QAI.  The Notice  Agent shall give prompt
notice of the  Liquidation  to RefTech and the Escrow Agent,  as provided for in
Section 4.6 of the Acquisition Agreement (the "Liquidation Notice"). The copy of
the Liquidation Notice sent to the Escrow Agent shall be accompanied by separate
stock powers,  duly executed in blank by each Principal being distributed Escrow
Shares by QAI,  sufficient  in form to permit the transfer of the Escrow  Shares
upon  delivery.  Such stock  powers  shall be part of the Escrow  Deposit.  Upon
receipt of the  Liquidation  Notice,  the Escrow  Agent shall  deliver the stock
certificate  evidencing  the Escrow  Shares  deposited  under this  Agreement to
RefTech,  for the sole purpose of reflecting  the change in record  ownership of
such Escrow  Shares.  RTI, by its execution of this  Agreement,  agrees to issue
certificates to each of the Principals as provided in the Liquidation Notice and
to deliver such reissued certificates to the Escrow Agent.

                  2.4 CLAIMS.  In the event that RefTech or RTI believes that it
may be entitled to  indemnification  as provided in Article X of the Acquisition
Agreement,  notice  thereof may be given to the Escrow  Agent (a "Pending  Claim
Notice",  provided evidence is delivered to the Escrow Agent that a copy thereof
has been  delivered  to the  Notice  Agent).  In the event  that  RefTech or RTI
becomes  entitled to  indemnification  as provided in such  Article X, then upon
determination thereof (a "Claim Amount"),  RefTech and/or RTI, as is applicable,
shall give the Notice Agent and the Escrow  Agent  notice  thereof (a "Notice of
Claim").  Unless RefTech or RTI, as the case may be, shall have received payment
in the full  amount of the Claim  Amount  within  thirty (30) days of its giving
such Notice of Claim,  it shall give  further  notice to the Escrow  Agent (with
evidence  that such notice has been  delivered  to the Notice  Agent) that it is
entitled to  indemnification,  in which event fifteen (15) days  thereafter  the
Escrow Agent shall cause to be delivered to RefTech or to RTI, out of the Escrow
Deposit,  such number of Escrow Shares as when  multiplied by their market value
per share, as herein  determined,  equals the Claim Amount.  For the purposes of
this Section, "market value" means the average closing price of the Common Stock
as quoted on NASDAQ or any  national  securities  exchange  on which the  Common
Stock may then be traded during the thirty (30) day period  immediately prior to
delivery  of such Notice of Claim to the Escrow  Agent,  and if at such time the
Common Stock is not so traded then at the most recent ask price as quoted by the
National Quotation Bureau, Inc., (or successor organization performing a similar
reporting function).

                  2.5 PENDING  CLAIM  NOTICE.  Each  Pending  Claim Notice shall
contain the following  information,  to the extent it is reasonably available to
RefTech or RTI:  (i)  RefTech's or RTI's good faith  estimate of the  reasonably
foreseeable  maximum amount of the Claim Amount; and (ii) a brief description in
reasonable detail of the facts, circumstances or events giving rise to the Claim
Amount.

                  2.6 NOTICE OF CLAIM.  Each Notice of Claim  shall  contain the
following information: (i) the Claim Amount; and (ii) a brief description of the
facts, circumstances or events giving rise to the Claim Amount.

                  2.7  TERMINATION  OF  ESCROW.  Within  thirty  (30) days after
receiving  notice from the Notice Agent (with  evidence  that a copy thereof has
been delivered to RefTech and RTI), given on or after the second  anniversary of
the date hereof,  the Escrow Agent shall  deliver to the Notice Agent any Escrow
Shares then held by it (other than any Escrow Shares the Escrow Agent reasonably


                                        2

<PAGE>

believes  [which belief may be based solely upon a written  statement of RefTech
or RTI, a copy of which has been delivered to the Notice Agent] may be needed to
satisfy a then  outstanding  Claim Amount which has not yet been fully satisfied
and any pending  Claim Amount  referred to in a then  outstanding  Pending Claim
Notice);  provided  that the Escrow  Agent shall  deliver any  remaining  Escrow
Shares then held by it six (6) months  thereafter,  unless there is then pending
an  arbitration  with respect  thereto  under  Section  12.5 of the  Acquisition
Agreement,  or a dispute  under  Section 3, in which event the Escrow  Agent may
continue to hold such Escrow Shares until conclusion of such arbitration. In all
other  cases,  the  Escrow  Agent  shall  deliver  to  RefTech,  QAI  and/or the
Principals, as the case may be, the certificates (and the related executed stock
powers)  representing the Escrow Deposit as set forth in joint instructions,  or
separate  instructions  of like effect,  signed and delivered by RefTech and the
Notice Agent.

                  2.8 DIVIDENDS AND VOTING.  Until  termination  of escrow,  all
dividends on the Escrow  Shares shall be retained by the Escrow Agent as part of
the Escrow Deposit.  Until the Escrow Deposit is released from escrow,  QAI, and
upon the  Liquidation  the  Principals,  shall be  entitled  to vote the  Escrow
Shares.

                  2.9 STOCK POWERS.  QAI and each of the Principals  shall, from
time to time,  at the  request of RefTech,  furnish the Escrow  Agent with stock
powers in blank  that will allow the Escrow  Agent to  perform  its  obligations
hereunder.  QAI and  each  of the  Principals  hereby  appoints  RefTech  as its
attorney-in-fact  to execute appropriate stock powers on its behalf in the event
that they, or any one of them, does not comply with RefTech's reasonable request
to furnish stock powers to the Escrow  Agent.  Such power of attorney may not be
revoked as long as this Agreement remains in effect. All such stock powers shall
be part of the Escrow Deposit.

                  2.10 NO ENCUMBRANCE. No interest in the Escrow Deposit, or any
beneficial  interest  therein,  may be pledged,  sold,  assigned or transferred,
other  than by  operation  of law,  by any  party  hereto  or  their  respective
successors  and  permitted  assigns,  or be taken  or  reached  by any  legal or
equitable  process in  satisfaction  of any debt or other  liability of any such
person, as long as this Agreement remains in effect.

                  3.  RESOLUTION  OF  DISPUTES.  In the  event  of  any  dispute
concerning  or arising  out of this  Agreement,  the parties in good faith shall
attempt to resolve the same.  In the event that the parties,  despite their good
faith efforts  cannot  resolve the dispute,  then any of such parties may demand
arbitration  of the  dispute  as  provided  in Section  12.5 of the  Acquisition
Agreement,  unless  the  Claim  Amount  is at issue  in  pending  or  threatened
litigation with a third party, in which event  arbitration  with respect thereto
may not be commenced  until such amount is  ascertained  or both RefTech and the
Notice Agent agree to arbitration.  The non-prevailing parties to an arbitration
hereunder  shall  pay  their  own  expenses,  the fees of each  arbitrator,  the
administrative  fee of the  American  Arbitration  Association  and the expenses
(including, without limitation, attorneys' fees and costs) incurred by the other
parties to the arbitration. Unless the Escrow Agent is determined to be at fault
by the  arbitration,  the Escrow  Agent  shall have a claim  against  the Escrow
Deposit for all of its expenses therein or arising in connection therewith.

                  4.  LIMITATION OF ESCROW AGENT'S LIABILITY.

                  4.1 LIMITATION.  The Escrow Agent will incur no liability with
respect to any action  taken or  suffered  by it in  reliance  upon any  notice,
direction,  instruction,  consent, statement or other document believed by it to
be genuine and duly authorized, nor for any other action or inaction, except its
own  willful  misconduct  or gross  negligence.  The  Escrow  Agent  will not be
responsible  for the validity or  sufficiency of this Agreement or any agreement
amendatory  or  supplemental   hereto.  In  all  questions  arising  under  this
Agreement,  the Escrow Agent may rely on the advice or opinion of legal counsel,
and for anything done, omitted or suffered in good faith by the


                                        3

<PAGE>



Escrow  Agent  based on such  advice or  opinion,  the Escrow  Agent will not be
liable to anyone.  The  Escrow  Agent  will not be  required  to take any action
hereunder  involving  any expense  unless the payment of such expense is made or
provided for in a manner satisfactory to it.

                  4.2 CONFLICTING DEMANDS. In the event that conflicting demands
are made upon, or  conflicting  notices are received by, the Escrow  Agent,  the
Escrow Agent will have the absolute right, at the Escrow Agent's election, to do
either or both of the following: (i) resign so that a successor can be appointed
pursuant to Section 8, or (ii) file a suit in  interpleader  and obtain an order
from a court of competent  jurisdiction  requiring the parties to interplead and
litigate  their several  claims and rights among  themselves.  In the event that
such an  interpleader  suit is brought,  the Escrow  Agent will thereby be fully
released and discharged from all further  obligations imposed upon it under this
Agreement,  the  Escrow  Agent  will have a priority  claim  against  the Escrow
Deposit for all costs,  expenses  and  reasonable  attorneys'  fees and expenses
expended or incurred by the Escrow  Agent under this  Agreement  and pursuant to
the  exercise of the Escrow  Agent's  rights under this  Section,  and the other
parties  to  this  Agreement,   jointly  and  severally,   shall  be  personally
responsible for payment of all such costs, expenses and fees.

                  4.3 INDEMNIFICATION IN FAVOR OF ESCROW AGENT. In consideration
of the Escrow Agent's  acceptance of its appointment as escrow agent  hereunder,
the other  parties  hereto,  jointly and  severally,  agree to (i) indemnify the
Escrow Agent, and hold the Escrow Agent harmless from, any liability incurred by
it to any  person,  firm or  corporation  by reason of its having  accepted  its
appointment  and in carrying  out any of the terms of this  Agreement,  and (ii)
reimburse  the Escrow Agent for all its costs and expenses,  including,  but not
limited to, reasonable  attorneys' fees and expenses,  incurred by reason of any
matter as to which an indemnity  is paid;  provided  that no indemnity  shall be
paid by reason of the Escrow Agent's gross negligence or willful misconduct.

                  4.4    ESCROW AGENT'S RESPONSIBILITIES

                         4.4.1 The Escrow Agent shall be under no  obligation to
deliver any  instrument  or  documents to a court or  arbitrator  or to take any
legal action in connection with this Agreement or towards its enforcement, or to
appear in,  prosecute or defend any action or  proceeding  which,  in the Escrow
Agent's  opinion,  would or  might  involve  it in any  cost,  expense,  loss or
liability unless, as often as the Escrow Agent may require,  the Escrow Agent is
furnished with security and indemnity reasonably  satisfactory to it against all
such costs, expenses, losses or liability.

                         4.4.2 The Escrow Agent's obligations hereunder shall be

any manner whatever for the sufficiency, correctness, genuineness or validity of
any  notice,  written  instructions  or  other  instrument  furnished  to  it or
deposited  with it,  or for the form of  execution  of any  thereof,  or for the
identity, authority or rights of any person executing,  furnishing or depositing
the same, except to the extent of its gross negligence or willful misconduct.

                         4.4.3 The  Escrow  Agent  shall not have any  duties or
responsibilities  except those set forth in this Agreement,  and shall not incur
any liability in acting upon any signature,  notice,  request,  waiver, consent,
receipt or other paper or document reasonably believed by it to be genuine,  and
the Escrow  Agent may presume that any person  purporting  to give any notice or
advice on behalf of any party in accordance with the provisions  hereof has been
duly authorized to do so.

                         4.4.4 The Escrow  Agent  shall be  entitled  to consult
with counsel in connection with its duties hereunder.

                         4.4.5 The  Escrow  Agent has  executed  this  Agreement

improvements  to the demised  premises  without the prior written consent of the
Lessor.  All fixtures  (including floor coverings),  alterations,  additions and
improvements  (except trade fixtures) put in at the expense of the Lessee, shall
be the property of the Lessor and shall remain upon and be surrendered  with the
demised premises as a part thereof at the termination of this Lease.

ENTRY:  The  Lessor  or his  representatives  shall  have the right to enter the
demised premises at all reasonable times to inspect and examine demised premises
and to make  alterations,  changes,  or repairs to the  demised  premises as are
herein  required or as Lessor may deem  necessary  for the  preservation  of the
demised premises.  Lessee shall not be entitled to any abatement or reduction of
rent by reason  thereof.  During the last  thirty  (30) days of the term of this
Lease or any  extension  thereof,  the Lessor  shall have the right to post "For
Lease"  and/or "For Sale" signs on the demised  premises  and during said period
the  Lessor or his  representatives  shall  have the  right to show the  demised
premises to prospective tenants or purchaser at all reasonable times.

SIGNS:  Lessee  shall not place any signs or  objects on the roof or any part of
the exterior of the building  (except on the plate glass  windows) nor place any
signs, show cases,  displays or fences on the sidewalks,  parking lot, driveways
or exterior of any  building on the demised  premises  except as and where first
approved in writing by Lessor.  Lessee shall remove all signs at the termination
of this Lease. Such installation and removals shall be made in such manner as to
avoid injury, defacement or overloading of the building or other improvements.

CONDEMNATION:  If the whole of the demised premises,  or such portion thereof as
will make premises  unusable for the purposes herein leased, be condemned by any
legally constituted  authority for any public use or purpose,  then in either of
said events the term hereby  granted  shall cease from the time when  possession
thereof is taken by public  authorities,  and rental shall be  accounted  for as
between Lessor and Lessee as of that date. Such termination,  however,  shall be
without   prejudice  to  the  right  of  either  Lessor  or  Lessee  to  recover
compensation and damage caused by condemnation from the condemnor. It is further
understood  and agreed that  neither the Lessee nor Lessor shall have any rights
in any award made to the other by any condemnation authority.

NOTICE:  Any demand to be made or notice to be given hereunder shall be made on,
or given to the Lessee either personally, or, at the Lessor's option, by sending
a copy of such demand or notice by mail  addressed  to the Lessee at the demised
premises.

WAIVER:  No waiver at any time of the right to terminate this Lease shall impair
the  right of the  Lessor  to  insist  upon  such  termination  in the  event of
subsequent breach or default by Lessee,  nor shall the acceptance of rent at any
time constitute such waiver of default or waiver of damages,  and in addition to
any other  remedies  which the  Lessor  may have,  the  Lessor may apply for and
obtain an  injunction  or use any other legal  process to enforce  the  Lessor's
rights.

MORTGAGES:  This Lease is and shall  always be  subordinate  to any  mortgage or
mortgages which now or shall at any time be placed upon the demised  premises or
any part thereof,  and the Lessee agrees to execute and deliver any  instrument,
without cost, which may be deemed necessary to further effect the  subordination
of this Lease to any such mortgage or mortgages.

LIEN: ALL PROPERTY OF THE LESSEE NOW OR HEREAFTER  PLACED IN OR UPON THE DEMISED
PREMISES  (EXCEPT SUCH PART OF THE  MERCHANDISE  THAT IS TO BE SOLD FROM TIME TO
TIME IN THE ORDINARY COURSE OF TRADE) IS HEREBY  SUBJECTED TO A LIEN IN FAVOR OF
THE LESSOR  AND SHALL BE AND  REMAIN  SUBJECT TO SUCH LIEN OF THE LESSOR FOR THE
PAYMENT OF ALL RENTS AND OTHER SUMS AGREED TO BE PAID BY THE LESSEE HEREIN. SAID
LIEN TO BE IN ADDITION TO ANY CUMULATIVE OF THE LANDLORD'S LIEN PROVIDED BY LAW.

POSSESSION:  If, for any reason,  the premises herein demised shall not be ready
for occupancy by the Lessee at the time of the commencement of this Lease,  this
Lease shall not be affected thereby, nor shall the Lessee have any claim against
the Lessor by reason thereof, but no rent shall be payable for the period during
which the premises shall not be ready for occupancy;  and all claims for damages
arising out of such delay are waived and  released  by the Lessee.  Rent for any
fractional  month  at the  beginning  or the  end of the  Lease  term  shall  be
prorated.

FIRE CLAUSE:  In the event that the premises hereby demised,  or the building of
which the same is a part,  shall be  partially  damaged by fire,  the  elements,
civil  disorder,  or other  casualty,  the Lessee  shall give  immediate  notice
thereof  to the  Lessor and the same  shall be  repaired  at the  expense of the
Lessor  without  unreasonable  delay.  Lessee shall receive an abatement of rent
proportionate to the damage to the demised  premises;  and in the event that the
damage  should be so extensive as to render the demised  premises  untenantable,
the rent shall cease until


                                      - 2 -

<PAGE>


such time as the premises  shall again be put into  repair,  but in the event of
the building  being  damaged by fire or otherwise to such an extent as to render
it  necessary in the judgment of the Lessor not to rebuild the same (and whether
or not the demised premises be affected), then, at the option of the Lessor, and
upon notice to Lessee,  and from  thenceforth this Lease shall cease and come to
an end, and the rent shall be apportioned and paid up to date of such damage. If
Lessor  elects to rebuild the  premises and  continue  this Lease,  Lessor shall
notify  Lessee  of such  intention  within  thirty  (30) days of the date of the
damage;  otherwise,  this Lease shall be deemed canceled and of no further force
and effect.

DEFAULT:  In the event that the Lessee  shall  default in the prompt  payment of
rent  when  the same is due,  or shall  violate  or omit to  perform  any of the
provisions of this Lease herein contained, or in the event that the Lessee shall
abandon the business or the premises or leave them vacant,  Lessor may, if he so
elects,  send  written  notice of such  default,  violation  or  omission to the
Lessee, by mail or otherwise,  at the demised premises,  and unless Lessee shall
have  completely  cured or removed said  default  within ten (10) days after the
sending of such  notice by Lessor,  Lessor may  thereupon  re-enter  the demised
premises,  by summary  proceedings or by force or otherwise without being liable
for  prosecution  therefor,  take  possession  of said  premises  and remove all
persons and  property  therefrom,  and may elect to either  cancel this Lease or
relet the  premises as agent for the Lessee or  otherwise,  and receive the rent
therefor,  applying the same first to the payment of such expenses as the Lessor
may be put to in  entering  and  letting;  and then to the  payment  of the rent
payable  under  this  Lease  and  the  fulfillment  of  the  Lessee's  covenants
hereunder; the balance (if any) to be paid to the Lessee who shall remain liable
for any deficiency.  On any sums due under the terms of this Lease placed in the
hands of an attorney after default or collected  through any judicial probate or
bankruptcy  proceedings,  Lessee  agrees  to pay a  reasonable  attorney's  fee,
together with all court costs. Past due installments of rent shall bear interest
at the rate of eight (8) per cent per annum until paid.  In the event the Lessee
shall continue to hold the demised premises, after demand therefor by Lessor, at
the termination of this Lease, or for default or breach of this Lease,  that the
Lessor shall be entitled to institute and maintain a Forcible Entry and Detainer
suit in the  Justice  Court  and  obtain a writ of  possession  for the  demised
premises.

BANKRUPTCY:  In the event that the Lessee  shall become  bankrupt,  voluntary or
involuntary,  or shall make a voluntary assignment for the benefit of creditors,
or in the event that a receiver for the Lessee shall be appointed,  then, at the
option of the  Lessor and upon ten (10) days  notice to the  Lessee or  Lessee's
representative,  of the exercise of such notice, this Lease shall cease and come
to an end.

SEVERABILITY:  In the event of litigation on this  instrument  and should one or
more clauses be found invalid all other  provisions of the lease are to stand as
written.

TAXES:  Lessor  agrees to pay before they become  delinquent  all real  property
taxes and assessments  lawfully levied or assessed  against the demised premises
or any part thereof, provided,  however, Lessor may, at his sole expense dispute
and contest  same,  and in such case,  such disputed item need not be paid until
finally  adjudged to be valid. If after one year from the  commencement  date of
this Lease,  the real estate taxes on the demised  premises are increased by any
taxing authority at any time during the remaining portion of the primary term or
any renewal or extension  thereof,  Lessee  agrees to pay to Lessor upon demand,
and as additional  rental,  an amount  monthly  equal to 1/12 of said  increase.
Lessee shall pay all taxes levied against personal property,  trade fixtures and
inventory placed by Lessee in, on or about the demised premises.

BINDING UPON PARTIES:  The Covenants and agreements herein contained shall inure
to the  benefit of and be binding  upon the  parties  hereto,  their  respective
heirs, legal representatives, successors and assigns.

         This Lease contains the entire  agreement  between the parties  hereto,
and no representations, warranties, express or implied, inducements, promises or
agreements, oral or otherwise,  between the parties not embodied herein shall be
of any force or effect.

                  EMPLOYMENT  AGREEMENT,  dated as of February 24, 1997, between
REFRIGERATION TECHNOLOGY INC., a Delaware corporation (the "Company"),  and RICK
E.  BACCHUS,  residing  at  ---------------------------------------,  New Mexico
- ----- ("Employee").

                  The Company desires to engage Employee to perform services for
the Company and its affiliates and (subject to Section 8) any successor or
assign of the Company, and Employee desires to perform such services, on the
terms and conditions hereinafter set forth.

                  1.       TERM
                           ----

                  The Company agrees to employ Employee,  and Employee agrees to
serve, on the terms and conditions of this  Agreement,  including the provisions
of Section 7 providing for early termination,  for a five year period commencing
with the date of the Closing,  as defined in that Acquisition  Agreement of even
date among the Company,  Quality Air, Inc.  ("QAI"),  Employee and others (which
provides for the  acquisition  by the Company of the business and  substantially
all of the assets of QAI).  If the Closing does not take place,  this  Agreement
and all obligations of each party hereunder  shall  immediately  terminate as if
never entered  into.  The period  during which  Employee is employed  under this
Agreement is referred to as the "Employment Period".

                  2.       DUTIES
                           ------

                           a.       During the Employment Period, Employee shall
devote his attention and energies to the business of the Company and its parent
and subsidiary companies (its "affiliates") on a full-time basis, and shall not
be engaged in any other business activity, whether or not such business activity
is pursued for gain, profit or other pecuniary advantage; but this shall not be
construed as preventing Employee from investing his assets in such manner as
will not require him to expend any material time or effort in regard thereto or
to perform any services in connection therewith.

                           b.       At all times during the Employment Period,
and thereafter if Employee continues in the employ of the Company or any of its
affiliates, Employee shall serve the Company and its affiliates faithfully,
diligently and in good faith.

                           c.       During the Employment Period, Employee shall
perform such services as may be required of him by the Company and its
affiliates, under and subject to the instructions, directions and control of the
Board of Directors of the Company and its chief executive officer (the "CEO",
which term shall mean the Company's Chairman if Employee is the chief executive
officer), to whom he shall report. Employee shall serve as President of the
Company. In addition, Employee shall serve as President of the Company's parent,
RTI Inc. ("RTI"), and in such capacity shall be under and subject to the
instructions, directions and control of the Board of Directors and of the chief
executive officer of RTI, unless Employee is chief executive officer of RTI, in
which event he also shall report to the Chairman of RTI. Employee's primary
responsibility shall be to perform those duties reasonably required of, and
related to, his position and such other duties as may be assigned to Employee
from time to time which are not inconsistent with those customarily assigned to
responsible executive employees.

                           d.       At all times during the Employment Period,
and thereafter if Employee continues in the employ of the Company or any of its
affiliates, Employee shall adhere to all rules and regulations that have been or
that hereafter may be established by the Company and its affiliates for the
conduct of their employees.

                           e.       Employee recognizes that he shall be
available to travel as the needs of the business require.


<PAGE>



                           f.       Employee represents that he is under no
contractual or other restriction or obligation which is inconsistent or in
conflict with his obligations under this Agreement or the rights of the Company
under this Agreement. Employee further represents that he is in good health,
with no chronic or recurring illness, and is insurable at normal rates. If
requested by the Company, Employee shall cooperate in applying for and
obtaining, at the Company's and RTI's expense, key-man insurance for the benefit
of the Company and RTI.

                  3.       COMPENSATION
                           ------------

                  As and for full and complete  compensation  to Employee  under
this Agreement,  the Company agrees to pay to him, and he agrees to accept,  the
following:

                           a.       The Company shall pay Employee during the
Employment Period an annual salary of no less than $80,000 (the "Base Salary")
payable in equal bi-weekly installments, or as otherwise may be the practice of
the Company in making salary payments.

                           b.       The Company, in its sole and absolute
discretion, may consider the granting of a bonus to Employee in such form and
amount, if any, as the Company may determine.

                           c.       All compensation paid to Employee shall be
subject to withholding and deductions to the extent required by applicable law.

                           d.       Employee shall be eligible to participate
in, and to be covered by, each life insurance, accident insurance, health
insurance and hospitalization, or other plan or benefit, if any, effective
generally (and not only with respect to a specific individual or individuals)
with respect to employees of the Company, if he shall be eligible under the
terms of such plan, without restriction or limitation by reason of this
Agreement. Nothing contained herein, however, shall be construed to require the
Company to establish any plans not in existence on the date hereof, to continue
any plans in existence on the date hereof, or to prevent the Company from
modifying and/or terminating any of the plans in existence on the date hereof,
and no such act or omission shall be deemed to affect this Agreement or any of
the provisions contained herein.

                           e.       During the Employment Term, Employee shall
be entitled to a vacation of three weeks, and also shall be entitled to all paid
holidays given by the Company to its employees generally. Vacation days not
taken shall not accumulate and shall not be available to Employee in subsequent
years of this Agreement. Vacations shall be coordinated with other executives of
the Company, the CEO and the Chairman or chief executive officer of RTI and
shall be scheduled by Employee with due regard to his activities with, and his
responsibilities for, the Company and its affiliates.

                           f.       Employee shall be entitled to reimbursement
for all reasonable out-of- pocket expenses incurred in performing his services
hereunder, within the limits of authority which may be established by the
Company from time to time, provided that Employee properly accounts for such
expenses in accordance with Company policy.

                  4.       NON-COMPETITION
                           ---------------

                  In view of the unique and  valuable  services  it is  expected
Employee  will render to the Company,  Employee's  knowledge  of the  customers,
trade secrets and other proprietary  information relating to the business of the
Company and its  customers and  suppliers  and similar  knowledge  regarding the
Company and its  affiliates  that it is expected  Employee  will obtain,  and in
consideration   of  the   acquisition   by  the  Company  of  the  business  and
substantially  all of the  assets  of QAI and the  compensation  to be  received
hereunder,  Employee  agrees that, for the greater of (a) five years  commencing
with the  Closing,  or (b) the period  during  which  Employee  continues  to be
employed  by the  Company  or  any  of  its  affiliates  plus  six  months  (the
"Restriction  Period"),  Employee  will not engage in, or otherwise  directly or
indirectly  be employed  by, or act as a  consultant  to, or be an owner of, any
other business or  organization  which may then be competing with the Company or
its affiliates;  provided,  however,  that if Employee's employment hereunder is
terminated by the Company without Cause, such


                                        2

<PAGE>



period of non-competition shall be limited to six months after such termination.
For  purposes  of this  Agreement,  mere  ownership  of not more  than 1% of the
outstanding  common stock of a corporation  registered  with the  Securities and
Exchange  Commission  under the  Securities  Exchange  Act of 1934  shall not be
deemed to be a violation of this Section.

                  5.       PATENTS, ETC.
                           ------------

                  Any  interest in  patents,  patent  applications,  inventions,
technological  innovations,   copyrights,   copyrightable  works,  developments,
discoveries,  designs,  and processes  (collectively,  the  "Inventions")  which
Employee now or hereafter during the Restriction  Period may own, conceive of or
develop,  and which  either  relate to the fields in which the Company or any of
its  affiliates  may then be  engaged  or  contemplates  being  engaged,  or are
conceived of or developed utilizing the time, assets,  facilities or information
of the Company or any of its affiliates, shall belong to the Company. As soon as
Employee owns, conceives of, or develops any Invention, he agrees immediately to
communicate such fact in writing to the CEO and the Chairman of RTI and, without
further compensation,  but at the Company's expense, forthwith shall execute all
such  assignments  and other  documents  (including  applications  for  patents,
copyrights,  trademarks, and assignments thereof) and take all such other action
as the Company may reasonably request in order (a) to vest in the Company, or as
the Company may direct,  all of Employee's  right,  title and interest in and to
the Inventions, free and clear of liens, mortgages, security interests, pledges,
charges and  encumbrances,  and (b) if  patentable or  copyrightable,  to obtain
patents or copyrights  (including  extensions and renewals)  therefor in any and
all countries and in such name as the Company may direct.

                  6.       CONFIDENTIAL INFORMATION
                           ------------------------

                  All confidential information which Employee may possess or may
obtain during the Restriction  Period relating to the business of the Company or
any of its affiliates or of any customer or supplier of any of them shall not be
published,  disclosed,  or made  accessible by him to any other person or entity
either during or after the  termination of his employment or used by him, except
during the Employment Period in the business and for the benefit of the Company,
without  prior  written  permission  of the Company.  Employee  shall return all
tangible evidence of such confidential information to the Company prior to or at
the termination of his employment. For purposes of this Agreement,  confidential
information does not include (a) information  which at the time of disclosure to
Employee is generally available to the public, (b) information which, subsequent
to disclosure to Employee,  becomes  generally  available to the public  without
fault  on  Employee's  part,  (c)  information  which is  known  in  general  to
Employee's profession or to the industry in which the Company is engaged, or (d)
knowledge of skills which are known in general to Employee's profession.

                  7.       TERMINATION.

                           a.       DEATH. In the event that Employee shall die
during the Employment Period, then, notwithstanding any other provisions hereof,
Employee's employment hereunder shall terminate forthwith. In addition to any
unpaid compensation then accrued, Employee's estate shall be entitled to receive
the proceeds of any life insurance on Employee's life if and to the extent then
maintained by the Company for Employee's sole benefit.

                           b.       DISABILITY. If Employee shall become
incapacitated during the Employment Period to such an extent that he shall be
unable to perform his duties hereunder, and such incapacity shall continue for
at least four consecutive weeks or for at least 45 days in any twelve-month
period, the Company may, at or at any time thereafter during the continuance of
such incapacity, give


                                        3

<PAGE>



notice to Employee of the  termination  of his  employment  hereunder  on a date
stated in such notice, and, in such event, Employee's employment hereunder shall
terminate  on such  date.  Such  termination  shall not  affect  any  disability
payments otherwise due hereunder to the Employee.

                           c.       FOR CAUSE. If, during the Employment Period,
the employment of Employee by the Company should terminate by reason of
Employee's voluntary action, or by the Company for "Cause", then the Company's
obligations for payment or delivery of salary, bonus, if any, and other
entitlements under this Agreement with respect to any future period shall
thereupon terminate. Written notice of termination for Cause shall be given by
the Company to Employee and shall be effective upon receipt. For purposes of
this Agreement, Cause consists of (1) Employee's (A) refusal to carry out
specific lawful directions of the Company's Board of Directors or of the CEO, or
the Board of Directors, Chairman or chief executive officer of RTI, which
directions shall not be inconsistent with the provisions of this Agreement, or
(B) refusal or failure to properly, adequately and fully perform part of his
duties or achieve the goals assigned to him (including among other things
achieving minimum levels of profitability as determined by the Company's Board
of Directors and/or RTI's Board of Directors) which are not in violation of this
Agreement, which refusal or failure is not remedied promptly, but in no event
later than five days after notice thereof to Employee, (2) Employee's commission
of an act of fraud, misappropriation or dishonesty (including falsification of
information given to the Company in connection with Employee's hire) to the
Company or any of its affiliates or falsification of a written document
delivered to the Company or any of its affiliates or on the Company's or such
affiliate's behalf, and (3) Employee's commission of a crime with respect to
which, in the reasonable judgment of the Company, Employee is likely to be
incarcerated or as result of which the Company, in its reasonable judgement,
determines it would be inappropriate for Employee to continue as an employee of
the Company.

                           d.       WITHOUT CAUSE. If, during the Employment
Period, the employment of Employee by the Company is terminated by the Company
without Cause, then the Company shall continue to pay Employee his salary for a
period of two months thereafter, and all other obligations of the Company for
payment or delivery of salary, bonus, if any, and other entitlements under this
Agreement with respect to any future period shall thereupon terminate.

                  8.       MISCELLANEOUS PROVISIONS.
                           ------------------------

                           a.       ENTIRE AGREEMENT. This Agreement sets forth
the entire agreement and understanding between the parties with respect to the
employment of Employee by the Company and supersedes all prior agreements,
arrangements and understandings between the parties with respect thereto.

                           b.       MODIFICATION AND WAIVER. This Agreement may
be amended, modified, superseded, canceled, renewed or extended, and the terms
or covenants hereof may be waived, only by an instrument executed by the party
to be charged or, in the case of a waiver, by the party waiving compliance. The
failure of either party at any time or times to require


                                        4

<PAGE>


performance  of any  provision  of this  Agreement in no manner shall affect the
right at a later time to enforce the same. No waiver by either party of a breach
of any term or  covenant  contained  in this  Agreement,  whether  by conduct or
otherwise, in any one or more instances, shall be deemed to be or construed as a
further or continuing  waiver of any such breach,  or a waiver of any other term
or covenant contained in this Agreement.

                           c.       NOTICES. All notices, demands, consents,
waivers and other communications ("Communications") given under this Agreement
may be in writing and shall be given (and shall be deemed to have been duly
given and received) upon the earlier of actual receipt, one business day after
being sent by overnight courier service or telecopier or three business days
after being sent by certified mail to the Company (to the attention of the CEO
and with a second copy to the Chairman of RTI) and to Employee, each at their
respective home addresses or to such other address as either party may hereafter
specify by notice to the other party. Simultaneously with sending a
Communication to the Company, a copy of the Communication shall be sent to RTI's
counsel (currently Warshaw Burstein Cohen Schlesinger & Kuh, LLP, 555 Fifth
Avenue, New York, New York 10017, Attention: Arthur Katz, Esq.). Irrespective of
the foregoing, notice of change of address shall be effective only upon receipt.

                           d.       GOVERNING LAW. This Agreement shall be

                                                                       EXHIBIT 5

                  EMPLOYMENT  AGREEMENT,  dated as of February 24, 1997, between
REFRIGERATION  TECHNOLOGY  INC., a Delaware  corporation  (the  "Company"),  and
ROCKNEY D.  BACCHUS,  residing at  ---------------------------------------,  New
Mexico ----- ("Employee").

                  The Company desires to engage Employee to perform services for
the Company and its affiliates and (subject to Section 8) any successor or
assign of the Company, and Employee desires to perform such services, on the
terms and conditions hereinafter set forth.

                  1.       TERM
                           ----

                  The Company agrees to employ Employee, and Employee agrees to
serve, on the terms and conditions of this Agreement, including the provisions
of Section 7 providing for early termination, for a five year period commencing
with the date of the Closing, as defined in that Acquisition Agreement of even
date among the Company, Quality Air, Inc. ("QAI"), Employee and others (which
provides for the acquisition by the Company of the business and substantially
all of the assets of QAI). If the Closing does not take place, this Agreement
and all obligations of each party hereunder shall immediately terminate as if
never entered into. The period during which Employee is employed under this
Agreement is referred to as the "Employment Period".

                  2.       DUTIES
                           ------

                           a.       During the Employment Period, Employee shall
devote his attention and energies to the business of the Company and its parent
and subsidiary companies (its "affiliates") on a full-time basis, and shall not
be engaged in any other business activity, whether or not such business activity
is pursued for gain, profit or other pecuniary advantage; but this shall not be
construed as preventing Employee from investing his assets in such manner as
will not require him to expend any material time or effort in regard thereto or
to perform any services in connection therewith.

                           b.       At all times during the Employment Period,
and thereafter if Employee continues in the employ of the Company or any of its
affiliates, Employee shall serve the Company and its affiliates faithfully,
diligently and in good faith.

                           c.       During the Employment Period, Employee shall
perform such services as may be required of him by the Company and its
affiliates, under and subject to the instructions, directions and control of the
Board of Directors of the Company and its President (the "President"), to whom
he shall report. Employee shall serve as Vice President - Development of the
Company. Employee's primary responsibility shall be to perform those duties
reasonably required of, and related to, his position and such other duties as
may be assigned to Employee from time to time which are not inconsistent with
those customarily assigned to responsible executive employees.

                           d.       At all times during the Employment Period,
and thereafter if Employee continues in the employ of the Company or any of its
affiliates, Employee shall adhere to all rules and regulations that have been or
that hereafter may be established by the Company and its affiliates for the
conduct of their employees.

                           e.       Employee recognizes that he shall be
available to travel as the needs of the business require.

                           f.       Employee represents that he is under no
contractual or other restriction or obligation which is inconsistent or in
conflict with his obligations under this Agreement or the rights of the Company
under this Agreement. Employee further represents that he is in good health,
with no chronic or recurring illness, and is insurable at normal rates. If
requested by the Company, Employee shall cooperate in applying for and
obtaining, at the Company's expense, key-man insurance for the benefit of the
Company.

                  3.       COMPENSATION
                           ------------

                  As and for full and complete compensation to Employee under
this Agreement, the Company agrees to pay to him, and he agrees to accept, the
following:

                           a.       The Company shall pay Employee during the
Employment Period an annual salary of no less than $80,000 (the "Base Salary")
payable in equal bi-weekly installments, or as otherwise may be the practice of
the Company in making salary payments.

                           b.       The Company, in its sole and absolute
discretion, may consider the granting of a bonus to Employee in such form and
amount, if any, as the Company may determine.

                           c.       All compensation paid to Employee shall be
subject to withholding and deductions to the extent required by applicable law.

                           d.       Employee shall be eligible to participate
in, and to be covered by, each life insurance, accident insurance, health
insurance and hospitalization, or other plan or benefit, if any, effective
generally (and not only with respect to a specific individual or individuals)
with respect to employees of the Company, if he shall be eligible under the
terms of such plan, without restriction or limitation by reason of this
Agreement. Nothing contained herein, however, shall be construed to require the
Company to establish any plans not in existence on the date hereof, to continue
any plans in existence on the date hereof, or to prevent the Company from
modifying and/or terminating any of the plans in existence on the date hereof,
and no such act or omission shall be deemed to affect this Agreement or any of
the provisions contained herein.

                           e.       During the Employment Term, Employee shall
be entitled to a vacation of three weeks, and also shall be entitled to all paid
holidays given by the Company to its employees generally. Vacation days not
taken shall not accumulate and shall not be available to Employee in subsequent
years of this Agreement. Vacations shall be coordinated with other Company
executives and the President and shall be scheduled by Employee with due regard
to his activities with, and his responsibilities for, the Company and its
affiliates.

                           f.       Employee shall be entitled to reimbursement
for all reasonable out-of-pocket expenses incurred in performing his services
hereunder, within the limits of authority which may be established by the
Company from time to time, provided that Employee properly accounts for such
expenses in accordance with Company policy.

                  4.       NON-COMPETITION
                           ---------------

                  In view of the unique and valuable services it is expected
Employee will render to the Company, Employee's knowledge of the customers,
trade secrets and other proprietary information relating to the business of the
Company and its customers and suppliers and similar knowledge regarding the
Company and its affiliates that it is expected Employee will obtain, and in
consideration of the acquisition by the Company of the business and
substantially all of the assets of QAI and the compensation to be received
hereunder, Employee agrees that, for the greater of (a) five years commencing
with the Closing, or (b) the period during which Employee continues to be
employed by the Company or any of its affiliates plus six months (the
"Restriction Period"), Employee will not engage in, or otherwise directly or
indirectly be employed by, or act as a consultant to, or be an owner of, any
other business or organization which may then be competing with the Company or
its affiliates; provided, however, that if Employee's employment hereunder is
terminated by the Company without Cause, such period of non-competition shall be
limited to six months after such termination. For purposes of this Agreement,
mere ownership of not more than 1% of the outstanding common stock of a
corporation registered with the Securities and Exchange Commission under the
Securities Exchange Act of 1934 shall not be deemed to be a violation of this
Section.

<PAGE>

                  5.       PATENTS, ETC.
                           ------------

                  Any interest in patents, patent applications, inventions,
technological innovations, copyrights, copyrightable works, developments,
discoveries, designs, and processes (collectively, the "Inventions") which
Employee now or hereafter during the Restriction Period may own, conceive of or
develop, and which either relate to the fields in which the Company or any of
its affiliates may then be engaged or contemplates being engaged, or are
conceived of or developed utilizing the time, assets, facilities or information
of the Company or any of its affiliates, shall belong to the Company. As soon as
Employee owns, conceives of, or develops any Invention, he agrees immediately to
communicate such fact in writing to the President and, without further
compensation, but at the Company's expense, forthwith shall execute all such
assignments and other documents (including applications for patents, copyrights,
trademarks, and assignments thereof) and take all such other action as the
Company may reasonably request in order (a) to vest in the Company, or as the
Company may direct, all of Employee's right, title and interest in and to the
Inventions, free and clear of liens, mortgages, security interests, pledges,
charges and encumbrances, and (b) if patentable or copyrightable, to obtain
patents or copyrights (including extensions and renewals) therefor in any and
all countries and in such name as the Company may direct.

                  6.       CONFIDENTIAL INFORMATION
                           ------------------------

                  All confidential information which Employee may possess or may
obtain during the Restriction Period relating to the business of the Company or
any of its affiliates or of any customer or supplier of any of them shall not be
published, disclosed, or made accessible by him to any other person or entity
either during or after the termination of his employment or used by him, except
during the Employment Period in the business and for the benefit of the Company,
without prior written permission of the Company. Employee shall return all
tangible evidence of such confidential information to the Company prior to or at
the termination of his employment. For purposes of this Agreement, confidential
information does not include (a) information which at the time of disclosure to
Employee is generally available to the public, (b) information which, subsequent
to disclosure to Employee, becomes generally available to the public without
fault on Employee's part, (c) information which is known in general to
Employee's profession or to the industry in which the Company is engaged, or (d)
knowledge of skills which are known in general to Employee's profession.

                  7.       TERMINATION.
                           -----------

                           a.       DEATH. In the event that Employee shall die
during the Employment Period, then, notwithstanding any other provisions hereof,
Employee's employment hereunder shall terminate forthwith. In addition to any
unpaid compensation then accrued, Employee's estate shall be entitled to receive
the proceeds of any life insurance on Employee's life if and to the extent then
maintained by the Company for Employee's sole benefit.

                           b.       DISABILITY. If Employee shall become
incapacitated during the Employment Period to such an extent that he shall be
unable to perform his duties hereunder, and such incapacity shall continue for
at least four consecutive weeks or for at least 45 days in any twelve-month
period, the Company may, at or at any time thereafter during the continuance of
such incapacity, give notice to Employee of the termination of his employment
hereunder on a date stated in such notice, and, in such event, Employee's
employment hereunder shall terminate on such date. Such termination shall not
affect any disability payments otherwise due hereunder to the Employee.

                           c.       FOR CAUSE. If, during the Employment Period,
the employment of Employee by the Company should terminate by reason of
Employee's voluntary action, or by the Company for "Cause", then the Company's
obligations for payment or delivery of salary, bonus, if any,

                                        3

<PAGE>

and other entitlements under this Agreement with respect to any future period
shall thereupon terminate. Written notice of termination for Cause shall be
given by the Company to Employee and shall be effective upon receipt. For
purposes of this Agreement, Cause consists of (1) Employee's (A) refusal to
carry out specific lawful directions of the Board of Directors or of the
President, which directions shall not be inconsistent with the provisions of
this Agreement, or (B) refusal or failure to properly, adequately and fully
perform part of his duties assigned to him which are not in violation of this
Agreement, which refusal or failure is not remedied promptly, but in no event
later than five days after notice thereof to Employee, (2) Employee's commission
of an act of fraud, misappropriation or dishonesty (including falsification of
information given to the Company in connection with Employee's hire) to the
Company or any of its affiliates or falsification of a written document
delivered to the Company or any of its affiliates or on the Company's or such
affiliate's behalf, and (3) Employee's commission of a crime with respect to
which, in the reasonable judgment of the Company, Employee is likely to be
incarcerated or as result of which the Company, in its reasonable judgement,
determines it would be inappropriate for Employee to continue as an employee of
the Company.

                           d.       WITHOUT CAUSE. If, during the Employment
Period, the employment of Employee by the Company is terminated by the Company
without Cause, then the Company shall continue to pay Employee his salary for a
period of two months thereafter, and all other obligations of the Company for
payment or delivery of salary, bonus, if any, and other entitlements under this
Agreement with respect to any future period shall thereupon terminate.

                  8.       MISCELLANEOUS PROVISIONS.
                           ------------------------

                           a.       ENTIRE AGREEMENT. This Agreement sets forth
the entire agreement and understanding between the parties with respect to the
employment of Employee by the Company and supersedes all prior agreements,
arrangements and understandings between the parties with respect thereto.

                           b.       MODIFICATION AND WAIVER. This Agreement may
be amended, modified, superseded, canceled, renewed or extended, and the terms
or covenants hereof may be waived, only by an instrument executed by the party
to be charged or, in the case of a waiver, by the party waiving compliance. The
failure of either party at any time or times to require performance of any
provision of this Agreement in no manner shall affect the right at a later time
to enforce the same. No waiver by either party of a breach of any term or
covenant contained in this Agreement, whether by conduct or otherwise, in any
one or more instances, shall be deemed to be or construed as a further or
continuing waiver of any such breach, or a waiver of any other term or covenant
contained in this Agreement.

                           c.       NOTICES. All notices, demands, consents,
waivers and other communications ("Communications") given under this Agreement
may be in writing and shall be given (and shall be deemed to have been duly
given and received) upon the earlier of actual receipt, one business day after
being sent by overnight courier service or telecopier or three business days
after being sent by certified mail to the Company (to the attention of the
President and with second copies to the Chairman of the Company and of the
Company's parent, if any) and to Employee, each at their respective home
addresses or to such other address as either party may hereafter specify by
notice to the other party. Simultaneously with sending a Communication to the
Company, a copy of the Communication shall be sent to the Company's counsel
(currently Warshaw Burstein Cohen Schlesinger & Kuh, LLP, 555 Fifth Avenue, New
York, New York 10017, Attention: Arthur Katz, Esq.). Irrespective of the
foregoing, notice of change of address shall be effective only upon receipt.

                           d.       GOVERNING LAW. This Agreement shall be
construed in accordance with and governed by the laws of the State of Delaware,
without regard to its principles of conflicts of laws.

                           e.       SURVIVAL. The covenants, agreements,
representations, and warranties contained in or made pursuant to this Agreement
shall survive the execution of this Agreement and the conclusion of the
Employment Period, irrespective of any investigation made by or on behalf of any
party.

                           f.       BINDING EFFECT. This Agreement shall be
binding upon and inure to the benefit of the parties and their respective legal
representatives, heirs, successors and permitted assigns.

                           g.       INVALIDITY. The invalidity of any part of
this Agreement is not intended to render invalid the remainder of this
Agreement. If any provision of this Agreement is so broad as to be
unenforceable, such provision is intended to be interpreted to be only so broad
as is enforceable.

Agreement as of the day and year first written above.

Section.

                  5.       PATENTS, ETC
                           ------------

                  Any interest in patents, patent applications, inventions,
technological innovations, copyrights, copyrightable works, developments,
discoveries, designs, and processes (collectively, the "Inventions") which
Employee now or hereafter during the Restriction Period may own, conceive of or
develop, and which either relate to the fields in which the Company or any of
its affiliates may then be engaged or contemplates being engaged, or are
conceived of or developed utilizing the time, assets, facilities or information
of the Company or any of its affiliates, shall belong to the Company. As soon as
Employee owns, conceives of, or develops any Invention, he agrees immediately to
communicate such fact in writing to the President and, without further
compensation, but at the Company's expense, forthwith shall execute all such
assignments and other documents (including applications for patents, copyrights,
trademarks, and assignments thereof) and take all such other action as the
Company may reasonably request in order (a) to vest in the Company, or as the
Company may direct, all of Employee's right, title and interest in and to the
Inventions, free and clear of liens, mortgages, security interests, pledges,
charges and encumbrances, and (b) if patentable or copyrightable, to obtain
patents or copyrights (including extensions and renewals) therefor in any and
all countries and in such name as the Company may direct.

                  6.       CONFIDENTIAL INFORMATION
                           ------------------------

                  All confidential information which Employee may possess or may
obtain during the Restriction Period relating to the business of the Company or
any of its affiliates or of any customer or supplier of any of them shall not be
published, disclosed, or made accessible by him to any other person or entity
either during or after the termination of his employment or used by him, except
during the Employment Period in the business and for the benefit of the Company,
without prior written permission of the Company. Employee shall return all
tangible evidence of such confidential information to the Company prior to or at
the termination of his employment. For purposes of this Agreement, confidential
information does not include (a) information which at the time of disclosure to
Employee is generally available to the public, (b) information which, subsequent
to disclosure to Employee, becomes generally available to the public without
fault on Employee's part, (c) information which is known in general to
Employee's profession or to the industry in which the Company is engaged, or (d)
knowledge of skills which are known in general to Employee's profession.

                  7.       TERMINATION.
                           -----------

                           a.       DEATH. In the event that Employee shall die
during the Employment Period, then, notwithstanding any other provisions hereof,
Employee's employment hereunder shall terminate forthwith. In addition to any
unpaid compensation then accrued, Employee's estate shall be entitled to receive
the proceeds of any life insurance on Employee's life if and to the extent then
maintained by the Company for Employee's sole benefit.

                           b.       DISABILITY. If Employee shall become
incapacitated during the Employment Period to such an extent that he shall be
unable to perform his duties hereunder, and such incapacity shall continue for
at least four consecutive weeks or for at least 45 days in any twelve-month
period, the Company may, at or at any time thereafter during the continuance of
such incapacity, give notice to Employee of the termination of his employment
hereunder on a date stated in such notice, and, in such event, Employee's
employment hereunder shall terminate on such date. Such termination shall not
affect any disability payments otherwise due hereunder to the Employee.

                           c.       FOR CAUSE. If, during the Employment Period,
the employment of Employee by the Company should terminate by reason of
Employee's voluntary action, or by the Company for "Cause", then the Company's
obligations for payment or delivery of salary, bonus, if any,


                                       3
<PAGE>

and other entitlements under this Agreement with respect to any future period
shall thereupon terminate. Written notice of termination for Cause shall be
given by the Company to Employee and shall be effective upon receipt. For
purposes of this Agreement, Cause consists of (1) Employee's (A) refusal to
carry out specific lawful directions of the Board of Directors or of the
President, which directions shall not be inconsistent with the provisions of
this Agreement, or (B) refusal or failure to properly, adequately and fully
perform part of his duties assigned to him which are not in violation of this
Agreement, which refusal or failure is not remedied promptly, but in no event
later than five days after notice thereof to Employee, (2) Employee's commission
of an act of fraud, misappropriation or dishonesty (including falsification of
information given to the Company in connection with Employee's hire) to the
Company or any of its affiliates or falsification of a written document
delivered to the Company or any of its affiliates or on the Company's or such
affiliate's behalf, and (3) Employee's commission of a crime with respect to
which, in the reasonable judgment of the Company, Employee is likely to be
incarcerated or as result of which the Company, in its reasonable judgement,
determines it would be inappropriate for Employee to continue as an employee of
the Company.

                           d.       WITHOUT CAUSE. If, during the Employment
Period, the employment of Employee by the Company is terminated by the Company
without Cause, then the Company shall continue to pay Employee his salary for a
period of two months thereafter, and all other obligations of the Company for
payment or delivery of salary, bonus, if any, and other entitlements under this
Agreement with respect to any future period shall thereupon terminate.

                  8.       MISCELLANEOUS PROVISIONS.

                           a.      ENTIRE AGREEMENT. This Agreement sets forth
the entire agreement and understanding between the parties with respect to the
employment of Employee by the Company and supersedes all prior agreements,
arrangements and understandings between the parties with respect thereto.

                           b.      MODIFICATION AND WAIVER. This Agreement may
be amended, modified, superseded, canceled, renewed or extended, and the terms
or covenants hereof may be waived, only by an instrument executed by the party
to be charged or, in the case of a waiver, by the party waiving compliance. The
failure of either party at any time or times to require performance of any
provision of this Agreement in no manner shall affect the right at a later time
to enforce the same. No waiver by either party of a breach of any term or
covenant contained in this Agreement, whether by conduct or otherwise, in any
one or more instances, shall be deemed to be or construed as a further or
continuing waiver of any such breach, or a waiver of any other term or covenant
contained in this Agreement.

                           c.       NOTICES. All notices, demands, consents,
waivers and other communications ("Communications") given under this Agreement
may be in writing and shall be given (and shall be deemed to have been duly
given and received) upon the earlier of actual receipt, one business day after
being sent by overnight courier service or telecopier or three business days
after being sent by certified mail to the Company (to the attention of the
President and with second copies to the Chairman of the Company and of the
Company's parent, if any) and to Employee, each at their respective home
addresses or to such other address as either party may hereafter specify by
notice to the other party. Simultaneously with sending a Communication to the
Company, a copy of the Communication shall be sent to the Company's counsel
(currently Warshaw Burstein Cohen Schlesinger & Kuh, LLP, 555 Fifth Avenue, New
York, New York 10017, Attention: Arthur Katz, Esq.). Irrespective of the
foregoing, notice of change of address shall be effective only upon receipt.

                           d.       GOVERNING LAW. This Agreement shall be
construed in accordance with and governed by the laws of the State of Delaware,
without regard to its principles of conflicts of laws.

                           e.       SURVIVAL. The covenants, agreements,
representations, and warranties contained in or made pursuant to this Agreement
shall survive the execution of this Agreement and the conclusion of the
Employment Period, irrespective of any investigation made by or on behalf of any
party.

                           f.       BINDING EFFECT. This Agreement shall be
binding upon and inure to the benefit of the parties and their respective legal
representatives, heirs, successors and permitted assigns.

                           g.       INVALIDITY. The invalidity of any part of
this Agreement is not intended to render invalid the remainder of this
Agreement. If any provision of this Agreement is so broad as to be
unenforceable, such provision is intended to be interpreted to be only so broad
as is enforceable.

                  IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement as of the day and year first written above.

review of QAI, and being satisfied as to the operations carried out by said
company and the liabilities assumed or incurred by QAI, REF-TECH will acquire
from SELLERS the Shares, for a price equal to the book value of the Shares (net

ARTICLE 2. - TRANSFER OF OPERATIONS.-
- -----------------------------------

         In the event that after carrying a due diligence review, REF-TECH

order to transfer such operations, including but not limited to executing an
Employer Substitution Agreement with NEWCO and notifying each and everyone of
