                                Re: Forbearance Letter

      Gentlemen:

                       This letter is  delivered  pursuant to that  certain Loan
      and Security Agreement dated as of December 22, 1998 (as from time to time
      amended,   restated,   supplemented  or  otherwise  modified,   the  "Loan
      Agreement")  by and among  Hawker  Pacific  Aerospace  ("U.S.  Borrower"),
      Hawker Pacific Aerospace Limited ("U.K.  Borrower" and,  collectively with
      U.S. Borrower, the "Borrowers"), Heller Financial, Inc., as Agent and as a
      Lender (the "Agent"),  NMB-Heller Limited, as Funding Agent and Collateral
      Agent,  and  the  other  Lenders  from  time to time  party  thereto.  All
      capitalized  terms used but not  otherwise  defined  herein shall have the
      respective meanings ascribed thereto in the Loan Agreement.

               Pursuant to paragraph (A) of the Financial Covenants Rider to the
      Loan Agreement,  the minimum  Tangible Net Worth required to be maintained
      as of December 31, 1998 was $21,500,000.  Pursuant to paragraph (B) of the
      Financial  Covenants  Rider  to the Loan  Agreement,  the  minimum  EBITDA
      required for the Fiscal Year ended as of December 31, 1998 was $7,000,000.
      Pursuant to paragraph (D) of the Financial  Covenants  Rider,  the minimum
      Fixed Charge  Coverage  permitted  for the twelve month period ended as of
      December  31,  1998 was  1.00:1.00.  Based  upon  your  monthly  financial
      statements  for the month ended  December 31, 1998 and for the Fiscal Year
      ended  as of such  date and the  Compliance  Certificate  for such  period
      delivered  in  connection  therewith,  actual  Tangible  Net  Worth  as of
      December 31, 1998 was $20,601,394, actual EBITDA for the Fiscal Year ended
      as of December 31, 1998 was  $4,808,129  and actual Fixed Charge  Coverage
      for the twelve  months  ended as of  December  31, 1998 was  .45:1:00.  In
      addition, pursuant to paragraph (L) of the Reporting Rider, Borrowers were
      required  to deliver,  no later than  January 31,  1999,  Projections  for
      Fiscal Year 1999,  prepared on a month-by-month  basis,  which Projections
      have not  delivered as of the date hereof;  this letter  hereby  serves as
      notice to you of such Default. Pursuant to subsection 8.1(C) of the Loan

Agreement,  such breaches of the covenants set forth in paragraphs  (A), (B) and
(D) of the Financial  Covenants  Rider  constitute  immediate  Events of Default
under  the  Loan  Agreement  and,  pursuant  to  subsection  8.1(E)  of the Loan
Agreement,  the  breach  of the  covenant  set  forth  in  paragraph  (L) of the
Reporting  Rider will  constitute an Event of Default if not remedied within ten
days after the date of this  letter.  Such  Events of Default  and such  Default
shall be collectively referred to herein as the "Existing Events of Default".

         Borrowers  hereby recognize and acknowledge that the Existing Events of
Default have occurred and are continuing. Borrowers hereby further recognize and
acknowledge  that,  absent the  effectiveness of this letter  agreement,  Agent,
Funding Agent,  Collateral  Agent and Lenders have the right, in accordance with
the  provisions  of the Loan  Agreement  and the other  Loan  Documents,  to (i)
immediately  cease making  additional Loans and issuing Lender Letters of Credit
and to cause their  obligation to lend their  respective  Pro Rata Shares of the
Commitments  to be  suspended;  (ii) declare all or any portion of the Loans and
all or some of the other  Obligations to be immediately due and payable together
with accrued  interest  thereon,  and to  terminate  the  obligations  of Agent,
Funding  Agent,  Collateral  Agent and  Lenders to make  Loans and issue  Lender
Letters of Credit; (iii) demand that Borrowers immediately deposit with Agent an
amount equal to 105% of the aggregate  outstanding  Letter of Credit  Reserve to
enable Agent or any Lender to make payments  under the Lender  Letters of Credit
when  required;  and (iv) exercise  such other rights and remedies  available to
Agent,  Funding Agent,  Collateral Agent and Lenders under the Loan Documents or
at law or in  equity,  including  without  limitation  the right to  immediately
enforce their Liens on the Collateral.

                  As a result of the Existing Events of Default,  you are hereby
formally  notified  that,  pursuant to and in  furtherance  of the verbal notice
given to you by  Agent  on  February  19,  1999,  Agent  has,  as of such  date,
established a reserve  against the Borrowing Base of  $5,000,000,  which reserve
shall remain in effect at all times from and after  February 19, 1999 until such
time, if any, as Agent shall give Borrowers written notice to the contrary.

                  You are  hereby  advised  that from and after the date of this
letter,  and  continuing  for so long as the  Existing  Events  of  Default  are
continuing,  Agent, Funding Agent,  Collateral Agent and Lenders hereby agree to
forbear from exercising the rights and remedies afforded Agent and Lenders under
the Loan  Agreement  and the other Loan  Documents  as a result of the  Existing
Events  of  Default  (other  than the  establishment  of a reserve  against  the
Borrowing  Base as set forth above,  which reserve may be maintained or modified
at any time by Agent in its sole  discretion  notwithstanding  the terms of this
letter), but only for the period commencing on the Effective Date of this letter
through the earlier of (a) the date on which a  Forbearance  Default  shall have
occurred and be continuing,  and (b) March 30, 1999 (the "Forbearance  Period"),
and only subject to the terms and conditions set forth in paragraphs (1) through
(6) below (collectively, the "Forbearance Conditions"):

                  (1)   Notwithstanding anything contained in the Loan Documents
     to the contrary (including without limitation that certain Post Closing
     Matters and Waiver Agreement dated as of the Closing Date), Borrowers shall
     (a) as promptly as practicable following the date hereof, establish or
     cause to be established the U.S. Blocked Accounts

         as required pursuant to subsection  4.26(A) of the Loan Agreement,  and
         (b) use their best efforts to, as promptly as practicable following the
         date hereof,  establish  or cause to be  established  the U.K.  Blocked
         Accounts  as  required  pursuant  to  subsection  4.26(B)  of the  Loan
         Agreement;

                  (2)  Notwithstanding  anything contained in the Loan Documents
         to  the  contrary  (including  without  limitation  the  provisions  of
         paragraph (F) of the Reporting Rider to the Loan  Agreement),  from and
         after the Effective Date and at all times  thereafter until Agent shall
         give Borrower  Representative written notice to the contrary,  Borrower
         Representative  shall deliver to Agent and Funding Agent Borrowing Base
         Certificates  on the second  Business Day of each week (as  appropriate
         for weekly use), setting forth the calculation of the Borrowing Base as
         of the  last  Business  Day  of the  immediately  preceding  week,  and
         otherwise in the form and containing the information  required pursuant
         to paragraph (F) of the Reporting Rider;

                  (3) As promptly as practicable  and in any event no later than
         March 30,  1999,  Borrowers  shall retain the services of a third party
         turnaround  consultant  acceptable to Agent to evaluate and assist,  if
         necessary,  in the turnaround efforts for the U.K. Borrower  (including
         without   limitation   those  efforts   described  in  the   turnaround
         implementation  plan required to be delivered pursuant to paragraph (4)
         below);

                  (4) On or prior to the Effective Date (notwithstanding the ten
         day grace period which might  otherwise be available  under  subsection
         8.1(E)  of the  Loan  Agreement),  Borrowers  shall  deliver  to  Agent
         Projections   for   Borrowers'   Fiscal   Year  1999,   prepared  on  a
         month-by-month basis, which Projections shall not forecast any material
         decline in Borrowers' financial condition or financial  performance for
         such  Fiscal  Year  from  that  set  forth  in  the  quarter-by-quarter
         Projections  for such Fiscal  Year  delivered  as of the Closing  Date,
         other than any such decline  resulting from the downward  adjustment in
         Borrowers'  EBITDA of  $3,546,000  effected as of December 31, 1998. In
         addition, on or prior to the Effective Date, Borrowers shall deliver to
         Agent  a  turnaround  implementation  plan  with  respect  to the  U.K.
         Borrower,  which plan shall be satisfactory to Agent in form, scope and
         substance; and

                  (5)  On  the  Effective  Date,  and  in  consideration  of the
         execution and delivery of this letter by Agent,  Borrowers shall pay to
         Agent a forbearance fee of $75,000, and thereafter,  without limitation
         of the provisions of subsection 10.1 of the Loan  Agreement,  Borrowers
         shall pay or reimburse Agent and Funding Agent for all fees,  costs and
         expenses incurred by them in connection with this letter,  the Existing
         Events of  Default,  any  Forbearance  Default  and/or any third  party
         consultants,  accountants or other  professionals  retained by Agent or
         Funding Agent in connection with the analysis or  implementation of any
         turnaround   plans  regarding  the  U.K.   Borrower  or  the  Borrowers
         collectively.

                   By  execution  of this  letter  agreement,  Borrowers  hereby
represent  and warrant that as of the date hereof,  no  Forbearance  Default has
occurred and is continuing. For purposes of this letter:

         (i) the term "Forbearance Default" means the occurrence and continuance
         of any Default or Event of Default  under the Loan  Agreement or any of
         the other Loan Documents other than the Existing Events of Default,  or
         the  failure  by  Borrowers  or  either  of  them  as of  any  date  of
         determination to satisfy any of the Forbearance  Conditions required to
         be satisfied as of such date; and

         (ii)  the  term  "Effective  Date"  shall  mean  the  date  on  which a
         counterpart  of  this  letter,  duly  executed  by  each  Borrower,  is
         delivered  to Agent,  together  with  payment  of the  forbearance  fee
         required pursuant to paragraph (5) of the Forbearance Conditions, which
         date  shall  occur  no later  than  March 6,  1999  (and the  foregoing
         agreement  to forbear  shall be of no force or effect if the  Effective
         Date does not occur on or prior to March 6. 1999).

                    The   foregoing   agreement  to  forbear  shall  be  limited
precisely as written and,  except as expressly  set forth in this letter,  shall
not be  deemed  to (i) be a waiver  of the  Existing  Events  of  Default  or of
Agent's,  Funding Agent's,  Collateral  Agent's or Lenders' right to exercise or
enforce any of their rights and remedies  under the Loan  Agreement or the other
Loan Documents,  as more fully described above; (ii) be a waiver or modification
of any other term or condition of the Loan Agreement or of any of the other Loan
Documents;  or (iii)  prejudice any right or rights which Agent,  Funding Agent,
Collateral  Agent or Lenders may now have or may have in the future  under or in
connection with the Loan Agreement or any of the other Loan Documents.

                  You are hereby further  advised that,  during the  Forbearance
Period,  the Agent may, in its sole discretion,  consider working with Borrowers
on a potential  restructuring of the credit  facilities  provided under the Loan
Agreement and the other Loan Documents, provided that you hereby acknowledge and
agree that (a) neither Agent,  Funding Agent,  Collateral Agent or any Lender is
obligated or in any way committed to enter into any such restructuring, (b) none
of Agent,  Funding Agent,  Collateral Agent or any Lender has sought or obtained
the approval of their  respective  internal  credit  authorities  as to any such
restructuring  or any potential  terms and conditions  thereof,  (c) this letter
shall not be deemed or  construed as  obligating  any of Agent,  Funding  Agent,
Collateral Agent or any Lender to seek or obtain any such approval,  and (d) the
terms and  conditions of any such  restructuring,  if one should occur,  are not
known at this time.  However,  you are hereby advised that in the event any such
restructuring were to be consummated,  one condition  precedent thereto would be
that, prior to or contemporaneously with any such restructuring,  the portion of
the  Subordinated  Debt of U.S.  Borrower  repaid to Unique on the Closing  Date
(which  repayment  was in the  amount of  $2,500,000)  would be  required  to be
reinvested  by Unique  in  Subordinated  Debt or other  junior  capital  of U.S.
Borrower,  in such form and on such terms and conditions as may be acceptable to
Agent at such time.

                  You are hereby further advised that,  except for the agreement
of Agent, Funding Agent, Collateral Agent and Lenders to forbear from exercising
their rights and remedies during the Forbearance

Period as set forth above,  Agent,  Funding Agent,  Collateral Agent and Lenders
expressly  reserve the right to exercise any or all of their rights and remedies
under the Loan Agreement and the other Loan Documents or otherwise now or at any
time hereafter.  None of the statements set forth in this letter, any prior oral
or written statements by Agent, Funding Agent, Collateral Agent or any Lender to
Borrowers,  the  making of further  advances  or other  extensions  of credit to
Borrowers,  or the  failure of Agent,  Funding  Agent,  Collateral  Agent or any
Lender to exercise any of its rights and remedies  against  Borrowers  now or at
any time in the  future,  shall be  deemed a waiver  of the  Existing  Events of
Default  described  herein, a waiver of any such rights and remedies or a waiver
or  modification  of any of the terms of the Loan  Agreement or any of the other
Loan Documents, all of which remain in full force and effect.

                                         Very truly yours,
