                                 Schedule 13D of
                             Michael E. Heisley, Sr.
                          and The Heico Companies, LLC
          with respect to the Common Stock, par value $0.0001 per share
                        of WorldPort Communications, Inc.


ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATIONS.

                  On January 25, 1999,  Heico (and Heisley,  indirectly  through
Heico)  acquired  securities  convertible  into  10,000,354  shares of WorldPort
Common Stock. The $32,500,000 purchase price for such securities was obtained by
Heico under its  existing  credit  facilities,  which are provided by a group of
banks for which  Bank of  America  serves as agent.  Heico  intends to fund such
purchases with funds obtained through its existing credit facilities.

ITEM 4.  PURPOSE OF TRANSACTION.

                  Heico  acquired the  securities  described in Item 2 above for
investment  purposes  and in  order to  provide  WorldPort  with  the  financing
necessary to satisfy certain obligations.

                  In connection with the transactions described in the preceding
paragraph,  Heico and WorldPort  entered into an agreement (the "Stock  Purchase
Agreement"),  pursuant to which WorldPort took all necessary actions to increase
the size of its  Board  of  Directors  to  eight  members  and to  appoint  four
individuals designated by Heico to serve as directors. WorldPort has also agreed
to cause  Heico's  designees  to  comprise  at least  one-half  of the boards of
directors of each of its subsidiaries. In addition, WorldPort amended its Bylaws
to provide  that at least one of Heico's  designees  and  (except in the limited
situation  regarding  certain proposed  refinancings of WorldPort's  outstanding
credit  facility)  one of the directors  who was not  designated by Heico,  must
approve any  proposed  action in order for such to be  properly  approved by the
Board of Directors.

                  In addition to the Stock Purchase Agreement,  Heico, WorldPort
and certain  stockholders  of  WorldPort  entered into a  Shareholder  Agreement
pursuant to which those  stockholders (i) agreed to not to vote certain of their
shares of capital stock of WorldPort in favor of certain financing  proposals or
other  items  without  Heico's  consent  and (ii)  granted to Heico a proxy with
respect to such capital  stock for Heico's use in limited  matters.  Pursuant to
the  Shareholder  Agreement,  Heico and the  stockholders  have  also  agreed to
certain  restrictions  on the  transfer of certain of their  shares of WorldPort
capital stock.

                  Neither Heisley nor Heico  presently has any definitive  plans
or proposals regarding an extraordinary corporate transaction, such as a merger,
reorganization or liquidation, involving WorldPort or its subsidiaries or a sale
or  transfer  of a  material  amount  of  assets  of  WorldPort  or  any  of its
subsidiaries.

                  Heisley  and Heico  reserve  the right to  acquire  additional
shares of WorldPort Common Stock, to dispose of shares of WorldPort Common Stock
or to formulate other purposes,  plans or proposals deemed  advisable  regarding
WorldPort.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

                  In addition to the securities described in Item 2 above, Heico
(and Heisley,  indirectly through his control of Heico) also owns 300,000 shares
of WorldPort  Common Stock.  Set forth below is a  description  of the WorldPort
Common  Stock  beneficially  owned by  Heisley,  Heico and each Heico  Reporting
Person.

matters as to which class voting rights exist) and (b) any corporation (or other
entity) which owns all the outstanding  Equity  Interests of the Company if such
entity  acquires such  ownership in a transaction  in which the former owners of
all the Equity Interests of the Company acquire  proportionate  ownership of the
Equity Interests (or similar equity  ownership  interest) of such entity (or any

similar equity ownership interest) of such entity).

average  life as of the date of  incurrence  thereof  which is  longer  than the

                                       13


<PAGE>



taxes  (including  quarterly  estimated  Federal  and state  income  taxes) with
respect to the Company's Taxable Income allocated,  or to be allocated,  to such
Members  ("Allocable  Taxable  Income").  The amount  payable as  Permitted  Tax
Distributions  in any applicable  Fiscal Year will be determined  separately for
ordinary  income  and  capital  gain,  and will  equal  the  product  of (i) the
Allocable  Taxable  Income  during  such Fiscal Year and (ii) a rate equal to 6%
plus the highest  marginal  Federal tax rate applicable to individuals from time
to time with  respect  to an amount of  Taxable  Income  equal to the  Allocable
Taxable  Income  during such Fiscal Year,  taking into account the  character of
such Taxable Income.  The Permitted Tax  Distributions for each Fiscal Year will
be adjusted to reflect any tax losses of the Company arising in any prior Fiscal
Year (assuming  that any such losses are carried  forward and used to offset the
Company's  Taxable  Income in the  applicable  Fiscal  Year) and to reflect  the
Company's  payment of any withholding  taxes that would give rise to a credit or
other tax benefit to the Company (or its direct or indirect Members).

         Permitted Tax Distributions  will be payable in quarterly  installments
during the applicable  Fiscal Year, in each case no more than five days prior to
the dates upon which  individuals  are legally  required to file their quarterly
estimated Federal income tax returns. Such quarterly payments will be based upon
the Company's then good faith estimate of its Allocable  Taxable Income for such
Fiscal Year.

         Upon  the  earlier  of  (i)  the  April  15  following  the  end of the
applicable  Fiscal  Year and (ii) the  filing  of a report on Form 10-K for such
Fiscal Year, the Company will make a  determination  of the aggregate  amount of
Permitted Tax  Distributions  for such Fiscal Year. Such  determination  will be
based upon the Allocable  Taxable Income during such Fiscal Year as reflected on
such  Federal  income  tax  return,  or if such  return is not  filed  when such
financial  statements  are filed  with the SEC,  the  Company's  then good faith
estimate of the amount of its Taxable Income for such Fiscal Year.

         If the aggregate  amount of Permitted Tax  Distributions  in any Fiscal
Year exceeds the amount determined by the Company,  each Member will be required
to promptly repay any such excess to the Company,  and no further  Permitted Tax
Distributions  will be paid to such  Member  until such  Member has repaid  such
excess to the  Company.  If the amount  determined  by the  Company  exceeds the
aggregate amount of Permitted Tax  Distributions in any Fiscal Year, the Company
will promptly pay that difference to the Members as a Permitted Tax Distribution
for such Fiscal  Year.  In  addition,  the  aggregate  amount of  Permitted  Tax
Distributions  will  be  adjusted  appropriately  under  certain  circumstances,
including in the event that the Company files an amended Federal


                                       14


<PAGE>



income tax return (or the Company files its original  return for the  applicable
Fiscal  Year if the  determination  of the  aggregate  amount of  Permitted  Tax
Distributions  for such  Fiscal  Year was based  upon the  Company's  good faith
estimate of its Taxable Income) or the Internal Revenue Service  determines that
information  reflected in the Company's Federal income tax return for a relevant
Fiscal Year is inaccurate or incomplete.

Agreement, each Bank, severally and for itself alone, agrees as follows:

         (a) Each Bank  agrees to make loans to either  Borrower  on a revolving
basis  ("Loans")  from time to time before the  Termination  Date in such Bank's
Percentage of such aggregate amounts as such Borrower may request from all Banks
hereunder; provided that the Total Outstandings shall not at any time exceed the

reasonably  satisfactory  to the  Issuing  Bank  (collectively  the  "Letters of
Credit" and individually  each a "Letter of Credit"),  at the request of and for

                                       18

or a Eurodollar Loan (each a "Type" of Loan),  as the applicable  Borrower shall
specify in the related notice of borrowing or conversion pursuant to Section 2.3

shall at all times be $1,000,000 or a higher integral multiple of $100,000.  All
borrowings, conversions, continuations and repayments of Loans shall be effected
so that each Bank will have a pro rata share  (according to its  Percentage)  of
all Types and Groups of Loans.

         2.3 Borrowing Procedures. The applicable Borrower shall give written or
telephonic notice to the Agent of each proposed  borrowing not later than (a) in
the case of a Base Rate  borrowing,  11:00 A.M.,  Chicago  time, on the proposed
date of such  borrowing,  and (b) in the case of a Eurodollar  borrowing,  11:00
A.M.,  Chicago  time,  at least two Business  Days prior to the proposed date of
such  borrowing.  Each such notice shall be effective upon receipt by the Agent,
shall be irrevocable,  and shall specify the date,  amount and Type of borrowing
and,  in the  case  of a  Eurodollar  borrowing,  the  initial  Interest  Period
therefor. Promptly upon receipt of such notice, the Agent shall advise each Bank
thereof.  Not later  than 2:00  p.m.,  Chicago  time,  on the date of a proposed
borrowing,  each Bank shall  provide  the Agent at the  principal  office of the
Agent  in  Chicago  with  immediately   available  funds  covering  such  Bank's
Percentage of such borrowing and,  subject to the satisfaction of the conditions
precedent  set forth in Section 11 with  respect  to such  borrowing,  the Agent
shall pay over the requested amount to the applicable  Borrower on the requested
borrowing  date.  Each  borrowing  shall be on a Business Day and shall be in an
aggregate amount of $1,000,000 or a higher integral multiple of $100,000. Unless
the applicable  Borrower shall otherwise direct in writing,  the proceeds of all
borrowings  shall be  deposited  to a demand  deposit  account of such  Borrower

         2.4      Procedures for Continuation or Conversion of Loan.

         (a) Subject to the provisions of Section 2.2, either Borrower may, upon
irrevocable  written  or  telephonic  notice  to the  Agent in  accordance  with
subsection (b) below,

                  (i) elect,  as of any  Business  Day,  to convert any Loans to
         such Borrower (or any part thereof in an aggregate amount of $1,000,000
         or a higher  integral  multiple  of  $100,000)  into Loans of the other
         Type; or

                  (ii)  elect,  as of the  last day of the  applicable  Interest
         Period,  to  continue  any  Eurodollar  Loans to such  Borrower  having
         Interest  Periods  expiring  on such  day (or any  part  thereof  in an
         aggregate  amount  of  $1,000,000  or a  higher  integral  multiple  of
         $100,000);

provided  that if at any time the  aggregate  amount of any Group of  Eurodollar
Loans is reduced,  by payment,  prepayment or conversion of part thereof,  to be
less than  $1,000,000,  such Eurodollar Loans shall  automatically  convert into
Base Rate Loans.

         (b) The applicable  Borrower shall give written or telephonic notice to
the Agent of each proposed  conversion or continuation  not later than (i) 11:00
A.M.,  Chicago  time,  at least  two  Business  Days in  advance  of the date of
conversion or  continuation,  if the Loans are to be converted into or continued
as  Eurodollar  Loans;  and  (ii)  11:00  A.M.,  Chicago  time,  on the  date of
conversion, if the Loans are to be converted into Base Rate Loans, specifying:

                  (A)      the proposed date of conversion or continuation
         (which shall be a Business Day);

                  (B)      the aggregate amount of Loans to be converted or
         continued;

                  (C) the Type of Loans  resulting from the proposed  conversion
         or continuation; and

                  (D) in the case of a  continuation  of,  or  conversion  into,
         Eurodollar Loans, the duration of the requested Interest Period.

         (c) If  upon  the  expiration  of any  Interest  Period  applicable  to
Eurodollar  Loans,  the  applicable  Borrower has failed to select  timely a new
Interest Period to be applicable to such Eurodollar  Loans,  such Borrower shall
be deemed to have elected to convert such Eurodollar  Loans into Base Rate Loans
effective as of the expiration date of such Interest Period.


                                       20


<PAGE>



         (d) The Agent will promptly notify each Bank of its receipt of a notice
of  conversion  or  continuation  pursuant to this Section 2.4, or, if no timely
notice is provided by the applicable  Borrower,  the Agent will promptly  notify
each Bank of the details of any automatic conversion.

         2.5 Letter of Credit Procedures. (a) The applicable Borrower shall give
notice to the Agent and the Issuing Bank of the proposed issuance of each Letter
of Credit for the account of such  Borrower on a Business  Day which is at least
two Business  Days (or such lesser  period as the Agent and the Issuing Bank may
agree)  prior to the  proposed  date of issuance of such Letter of Credit.  Each
such  notice  shall be  accompanied  by a Letter  of  Credit  Application,  duly
executed by the applicable Borrower and in all respects reasonably  satisfactory
to the Issuing Bank,  together with such other documentation as the Issuing Bank
may reasonably request in support thereof,  it being understood that each Letter
of Credit  Application shall specify,  among other things, the date on which the
proposed Letter of Credit is to be issued, the expiration date of such Letter of
Credit (which shall not be later than the then-scheduled Termination Date unless
the applicable Borrower shall have pledged cash collateral to the Agent therefor
in an amount,  and pursuant to  documentation,  reasonably  satisfactory  to the
Required  Banks  and the  Agent)  and  whether  such  Letter  of Credit is to be
transferable in whole or in part.  Subject to the satisfaction of the conditions
precedent set forth in Section 11 with respect to the issuance of such Letter of
Credit,  the Issuing  Bank shall  issue such  Letter of Credit on the  requested
issuance date.

         (b) The Borrower, the Banks, the Issuing Bank and the Agent agree that,
on the Effective  Date,  each Existing  Letter of Credit shall be deemed to have
been  issued for the  account of the  Company (or jointly for the account of the
Company and any applicable  Subsidiary) hereunder and to be subject to the terms
and provisions hereof.

         2.6 Participations in Letters of Credit. Concurrently with the issuance
of each Letter of Credit (or, with respect to each Existing Letter of Credit, on
the  Effective  Date),  the  Issuing  Bank  shall  be  deemed  to have  sold and
transferred to each other Bank, and each other Bank shall be deemed  irrevocably
and  unconditionally  to have  purchased  and  received  from the Issuing  Bank,
without recourse or warranty,  an undivided interest and  participation,  to the
extent of such  other  Bank's  Percentage,  in such  Letter  of  Credit  and the
applicable  Borrower's  reimbursement  obligations with respect thereto. For the
purposes of this Agreement,  the unparticipated portion of each Letter of Credit
shall be deemed to be the Issuing Bank's  "participation"  therein.  The Issuing
Bank hereby agrees,  upon request of any Bank, to deliver to such Bank a list of
all outstanding Letters of Credit,


                                       21


<PAGE>



together with such information related thereto as such other Bank may reasonably
request.

         2.7 Reimbursement Obligations. Each Borrower hereby unconditionally and
irrevocably   agrees  to  reimburse   the  Issuing  Bank  for  each  payment  or
disbursement  made by the Issuing Bank under any Letter of Credit issued for the
account of such Borrower honoring any demand for payment made by the beneficiary
thereunder,  in each case on the date that such payment or disbursement is made.
Any amount not reimbursed on the date of such payment or distribution shall bear
interest  from the date of such  payment  or  disbursement  to the date that the
Issuing Bank is  reimbursed  by the  applicable  Borrower  therefor,  payable on
demand,  at a rate per annum equal to the sum of the Base Rate from time to time
in effect  plus the Margin  plus,  beginning  on the second  Business  Day after
demand by the Issuing  Bank,  2%. The  Issuing  Bank shall  promptly  notify the
applicable  Borrower whenever any demand for payment is made under any Letter of
Credit  issued for the account of such Borrower by the  beneficiary  thereunder;
provided that the failure of the Issuing Bank to so notify such  Borrower  shall
not affect the rights of the Issuing Bank or the Banks in any manner whatsoever.

         2.8  Limitation  on the  Issuing  Bank's  Obligations.  In  determining
whether  to pay under any  Letter of  Credit,  the  Issuing  Bank  shall have no
obligation  to  either  Borrower  or any Bank  other  than to  confirm  that any
documents  required to be delivered  under such Letter of Credit  appear to have
been delivered and appear to comply on their face with the  requirements of such
Letter of Credit.  Any action  taken or omitted to be taken by the Issuing  Bank
under or in  connection  with any Letter of  Credit,  if taken or omitted in the
absence of gross  negligence and willful  misconduct,  shall not impose upon the
Issuing Bank any  liability to either  Borrower or any Bank and shall not reduce
or impair  the  applicable  Borrower's  reimbursement  obligations  set forth in
Section 2.7 or the obligations of the Banks pursuant to Section 2.9.

         2.9 Funding by Banks to the Issuing Bank. If the Issuing Bank makes any
payment or disbursement  under any Letter of Credit and the applicable  Borrower
has not reimbursed the Issuing Bank in full for such payment or  disbursement by
11:00 A.M., Chicago time, on the date of such payment or disbursement, or if any
reimbursement received by the Issuing Bank from or on behalf of a Borrower is or
must be returned or rescinded upon or during any bankruptcy or reorganization of
such  Borrower or  otherwise,  each other Bank shall be  obligated to pay to the
Issuing  Bank,  in  full  or  partial  payment  of  the  purchase  price  of its
participation  in such Letter of Credit,  its pro rata share  (according  to its
Percentage) of such payment or disbursement  (but no such payment shall diminish
the obligations of the applicable Borrower under


                                       22


<PAGE>



Section 2.7), and the Agent shall promptly notify each other Bank thereof.  Each
other Bank  irrevocably  and  unconditionally  agrees,  severally and for itself
alone, to so pay to the Agent in immediately  available funds for the account of
the Issuing Bank the amount of such other Bank's  Percentage  of such payment or
disbursement.  If and to the  extent  any Bank  shall not have made such  amount
available to the Agent by 2:00 P.M.,  Chicago time, on the Business Day on which
such Bank receives notice from the Agent of such payment or disbursement or such
return or rescission of reimbursement  (it being understood that any such notice
received  after noon,  Chicago time, on any Business Day shall be deemed to have
been  received  on the next  following  Business  Day),  such Bank agrees to pay
interest  on such  amount to the  Agent  for the  account  of the  Issuing  Bank
forthwith  on  demand  for each day from the date such  amount  was to have been
delivered  to the  Agent to the date such  amount  is paid,  at a rate per annum
equal to (a) for the first three days after demand,  the Federal Funds Rate from
time to time in effect  and (b)  thereafter,  the Base Rate from time to time in
effect.  Any Bank's failure to make available to the Agent its Percentage of any
such payment or disbursement or such return or rescission of reimbursement shall
not relieve any other Bank of its obligation  hereunder to make available to the
Agent  such  other  Bank's  Percentage  of such  amount,  but no Bank  shall  be
responsible  for the  failure of any other Bank to make  available  to the Agent
such other Bank's  Percentage of any such payment or disbursement or such return
or rescission of reimbursement.

         2.10  Warranty.  Each notice of borrowing,  continuation  or conversion
pursuant  to  Section  2.3 or 2.4 and the  delivery  of each  Letter  of  Credit
Application pursuant to Section 2.5 shall automatically constitute a warranty by
the  Borrowers to the Agent and each Bank to the effect that on the date of such
requested borrowing, continuation or conversion or the issuance of the requested
Letter  of  Credit,  as the case may be,  (a) the  warranties  of the  Borrowers
contained in Section 9 (excluding  Sections 9.5, 9.6 and 9.8) of this  Agreement
shall be true and correct as of such  requested  date as though made on the date
thereof  and (b) no Event of Default or  Unmatured  Event of Default  shall have
then occurred and be continuing or will result therefrom.

         2.11 Conditions. Notwithstanding any other provision of this Agreement,
(a) no Bank shall be obligated to make any Loan,  (b) no Bank shall be obligated
to convert into or permit the continuation at the end of the applicable Interest
Period of any Eurodollar Loan and (c) the Issuing Bank shall not be obligated to
issue  any  Letter  of  Credit  if, in any such  case,  an Event of  Default  or
Unmatured Event of Default exists or would result therefrom.

<PAGE>



         2.12 Commitments  Several.  The failure of any Bank to make a requested
Loan on any date shall not  relieve any other Bank of its  obligation  to make a
Loan on such date, but no Bank shall be responsible for the failure of any other
Bank to make any Loan to be made by such other Bank.

         SECTION 3  NOTES EVIDENCING LOANS.

         3.1 Notes.  The Loans of each Bank to each Borrower  shall be evidenced
by a promissory note  (individually each a "Note" and collectively for all Banks
the  "Notes")  of such  Borrower  substantially  in the form of  Exhibit A, with
appropriate insertions,  dated the Effective Date (or such earlier date as shall
be  satisfactory  to the Agent),  payable to the order of such Bank in an amount
equal to such Bank's  Commitment (or, if less, in the aggregate unpaid principal
amount of all of such Bank's Loans) on the Termination Date.

         3.2  Recordkeeping.  Each Bank shall record in its records the date and
amount of each Loan made by such Bank, each repayment or conversion thereof and,
in the case of each Eurodollar Loan, the dates on which each Interest Period for
such Loan shall begin and end. The aggregate unpaid principal amount so recorded
shall be  rebuttable  presumptive  evidence of the  principal  amount  owing and
unpaid on the  applicable  Note of such Bank.  The failure to so record any such
amount or any error in so recording any such amount shall not, however, limit or
otherwise affect the obligations of the applicable  Borrower  hereunder or under
any Note to repay  the  principal  amount of the  Loans  evidenced  by such Note
together with all interest accruing thereon.

         SECTION 4  INTEREST.

         4.1  Interest  Rates.  Each  Borrower  promises to pay  interest on the
unpaid  principal  amount of each Loan to such  Borrower for the period from the
date of such Loan to the date such Loan is paid in full, as follows:

                  (a) at all times  while  such Loan is a Base Rate  Loan,  at a
         rate per annum equal to the Base Rate from time to time in effect; and

                  (b) at all times while such Loan is a  Eurodollar  Loan,  at a
         rate  per  annum  equal  to the  sum of the  Eurodollar  Rate  (Reserve
         Adjusted)  applicable  to each  Interest  Period for such Loan plus the
         Margin from time to time in effect;

provided,  however,  that at any time an Event of Default  exists,  the interest
rate applicable to each Loan shall be increased by 2%.


                                       24


<PAGE>



         4.2 Interest  Payment  Dates.  Accrued  interest on each Base Rate Loan
shall be  payable  on the last day of each  calendar  quarter  and at  maturity.
Accrued  interest  on each  Eurodollar  Loan shall be payable on the last day of
each Interest  Period relating to such Loan (and, in the case of each Eurodollar
Loan with an  Interest  Period in excess of three  months,  on each  three-month
anniversary  of the first day of such  Interest  Period) and at maturity.  After
maturity, accrued interest on all Loans shall be payable on demand.

         4.3 Setting and Notice of Eurodollar  Rates. The applicable  Eurodollar
Rate for each  Interest  Period  shall be  determined  by the Agent,  and notice
thereof shall be given by the Agent promptly to the applicable Borrower and each
Bank. Each determination of the applicable Eurodollar Rate by the Agent shall be
conclusive and binding upon the parties  hereto,  in the absence of demonstrable
error. The Agent shall,  upon written request of the applicable  Borrower or any
Bank, deliver to such Borrower or such Bank a statement showing the computations
used by the Agent in determining any applicable Eurodollar Rate hereunder.

         4.4 Computation of Interest.  Interest on Base Rate Loans when the Base
Rate is determined by reference to BofA's  reference  rate shall be computed for
the  actual  number  of days  elapsed  on the  basis  of a year  of 365  or,  if
applicable, 366 days. All other interest shall be computed for the actual number
of days elapsed on the basis of a year of 360 days. The applicable interest rate
for each Base Rate Loan shall change simultaneously with each change in the Base
Rate.

         SECTION 5  FEES.

         5.1 Non-Use Fee. The Borrowers  jointly and  severally  agree to pay to
the Agent for the  account of each Bank a non-use  fee,  for the period from the
Effective Date to the Termination  Date at a rate per annum equal to the Non-Use
Fee Rate from  time to time in  effect,  on the  unused  amount  of such  Bank's
Commitment. Such non-use fee shall be payable in arrears on the last day of each
calendar  quarter and on the Termination  Date, in each case for the period then
ending for which such  non-use  fee shall not have been  theretofore  paid.  The
non-use fee shall be computed for the actual number of days elapsed on the basis
of a year of 365 or, if applicable, 366 days.

         5.2 Letter of Credit Fees. (a) Each Borrower agrees to pay to the Agent
for the account of the Banks pro rata according to their respective  Percentages
a letter of credit fee for each stand-by Letter of Credit issued for the account
of such  Borrower  at a rate per annum  equal to the Margin from time to time in
effect multiplied by the maximum amount available to be drawn


                                       25


<PAGE>



under such Letter of Credit from time to time, computed for the actual number of
days  elapsed  on the basis of a year of 360 days and  payable in arrears on the
last day of each calendar  quarter and on the Termination  Date (and thereafter,
if  applicable,  on demand) for the period from the date of the issuance of such
Letter of Credit to the date such  payment  is due or, if  earlier,  the date on
which such Letter of Credit expired or was terminated.

         (b) Each  Borrower  agrees to pay to the Agent for the  account  of the
Banks pro rata  according to their  respective  Percentages  an issuance fee for
each  commercial  Letter of Credit issued for the account of such Borrower in an
amount  equal to the  greater  of  0.125% of the face  amount of such  Letter of
Credit  and $75.  Such fee shall be  payable  in arrears on the last day of each
calendar  quarter  and on the  Termination  Date for all  commercial  Letters of
Credit for which such fee has not previously been paid.

         (c) In addition,  each Borrower agrees,  with respect to each Letter of
Credit issued for the account of such Borrower, to pay to the Issuing Bank (i) a
fronting fee in an amount  mutually  agreed to by such  Borrower and the Issuing
Bank and (ii) such reasonable fees and expenses as the Issuing Bank  customarily
requires  in  connection  with  the  issuance,  negotiation,  processing  and/or
administration of letters of credit in similar situations.

         (d) With  respect to the  Existing  Letters of  Credit,(i)  the Company
shall only be  responsible  for fees  pursuant to clauses (a) and (b) above with
respect to such Letters of Credit  commencing on the Effective Date and (ii) the
Company shall be responsible for fees and expenses  pursuant to clause (c) above
only to the extent not previously paid in respect of such Letters of Credit.

         5.3  Agent's  Fees.  The  Company  agrees to pay to the Agent  periodic
agent's fees at such times and in such  amounts as are  mutually  agreed upon by
the Company and the Agent.

         SECTION 6         REDUCTION OR TERMINATION OF THE COMMITMENTS;

                           PREPAYMENTS.

         6.1      Voluntary Reduction or Termination of Commitments.  The
                  -------------------------------------------------
Borrowers may from time to time on at least five Business Days'
prior written notice received by the Agent (which shall promptly
advise each Bank thereof) permanently reduce the aggregate amount
of the Commitments to an amount not less than the Total
Outstandings.  Any such reduction shall be in an aggregate amount
of $5,000,000 or a higher integral multiple of $1,000,000.  The
Borrowers may at any time on like notice terminate the
Commitments upon payment in full of all Loans and all other


                                       26


<PAGE>



obligations of the Borrowers hereunder.  All reductions of the Commitments shall
be pro rata among the Banks according to their respective Percentages.

         6.2 Prepayments.  Either Borrower may from time to time prepay Loans to
such  Borrower in whole or in part,  provided that (a) the  applicable  Borrower
shall give the Agent  (which shall  promptly  advise each Bank)  written  notice
thereof not less than one Business Day prior to such prepayment,  in the case of
Base Rate Loans,  and not less than two Business Days prior to such  prepayment,
in the case of Eurodollar Loans, in each case specifying the Loans to be prepaid
and the date and amount of prepayment,  and (b) each partial prepayment shall be
in an integral  multiple of $100,000.  Any prepayment of a Eurodollar Loan shall
include accrued interest to the date of prepayment on the principal amount being
repaid, and any prepayment of a Eurodollar Loan prior to the end of the Interest
Period therefor shall be subject to Section 8.4.

         SECTION 7  MAKING AND PRORATION OF PAYMENTS; SETOFF; TAXES.

         7.1 Making of Payments. All payments of principal of or interest on the
Loans, and of all fees, shall be made by the applicable Borrower to the Agent in
immediately  available  funds at its  office in  Chicago  not later  than  noon,
Chicago  time,  on the date due;  and funds  received  after  that hour shall be
deemed to have been  received by the Agent on the next  following  Business Day.
Each Borrower  hereby  authorizes the Agent to charge any demand deposit account
of such Borrower  maintained with BofA for the amount of any such payment on the
due date therefor, but the Agent's failure to so charge such account shall in no
way affect the  obligation of such Borrower to make any such payment.  The Agent
shall  promptly  remit to each Bank its share of all such  payments  received in
collected funds by the Agent for the account of such Bank.

         All payments under Sections 8.1 and 8.4 shall be made by the applicable
Borrower directly to the Bank or Banks entitled thereto.

         7.2 Application of Certain Payments. Each payment of principal shall be
applied to such Loans as the  applicable  Borrower  shall direct by notice to be
received  by the Agent on or before the date of such  payment or, in the absence
of such  notice,  as the Agent shall  determine  in its  reasonable  discretion.
Concurrently  with each remittance to any Bank of its share of any such payment,
the Agent shall advise such Bank as to the application of such payment.

         7.3      Due Date Extension.  If any payment of principal or
interest with respect to any of the Loans, or of any fees, falls


                                       27


<PAGE>



due on a day which is not a Business  Day,  then such due date shall be extended
to the next following  Business Day (unless,  in the case of a Eurodollar  Loan,
such next following  Business Day is the first Business Day of a calendar month,
in which case such due date shall be the  immediately  preceding  Business  Day)
and, in the case of principal,  additional  interest shall accrue and be payable
for the period of any such extension.

         7.4 Setoff.  Each Borrower agrees that the Agent and each Bank have all
rights of set-off and bankers' lien provided by applicable  law, and in addition
thereto,  each Borrower  agrees that at any time (a) any payment or other amount
owing by such Borrower under this Agreement is then due to the Agent or any Bank
or (b) any  Unmatured  Event of  Default  under  Section  12.1.4 or any Event of
Default exists, the Agent and each Bank may apply to the payment of such payment
or other  amount  (or,  in the case of  clause  (b),  to any  obligation  of the
applicable  Borrower  hereunder,  whether or not then due) any and all balances,
credits,  deposits,  accounts or moneys of such Borrower then or thereafter with
the Agent or such Bank.

         7.5  Proration  of  Payments.  If any Bank shall  obtain any payment or
other  recovery  (whether  voluntary,  involuntary,  by application of offset or
otherwise)  on account of  principal of or interest on any Loan in excess of its
pro rata share of payments and other recoveries obtained by all Banks on account
of  principal  of and interest on Loans then held by them (other than in respect
of an Affected Loan or as a result of  replacement of a Bank pursuant to Section
8.7),  such Bank shall purchase from the other Banks such  participation  in the
Loans held by them as shall be necessary to cause such  purchasing Bank to share
the  excess  payment  or other  recovery  ratably  with each of them;  provided,
however,  that if all or any portion of the excess  payment or other recovery is
thereafter  recovered from such purchasing Bank, the purchase shall be rescinded
and the purchase price restored to the extent of such recovery.

         SECTION 8         INCREASED COSTS; SPECIAL PROVISIONS FOR EURODOLLAR
                           LOANS.

         8.1 Increased Costs. (a) If, after the date hereof, the adoption of, or
any change in, any  applicable  law,  rule or  regulation,  or any change in the
interpretation or administration thereof by any governmental authority,  central
bank or comparable  agency  charged with the  interpretation  or  administration
thereof,  or compliance by any Bank (or any Eurodollar Office of such Bank) with
any  request or  directive  (whether or not having the force of law) of any such
authority, central bank or comparable agency

                  (A) shall subject any Bank (or any  Eurodollar  Office of such
         Bank) to any tax, duty or other charge with respect


                                       28


<PAGE>



         to its Eurodollar Loans, its Notes or its obligation to make Eurodollar
         Loans, or shall change the basis of taxation of payments to any Bank of
         the  principal  of or  interest  on its  Eurodollar  Loans or any other
         amounts due under this Agreement in respect of its Eurodollar  Loans or
         its obligation to make Eurodollar Loans (except for changes in the rate
         of tax on the overall net income of such Bank or its Eurodollar  Office
         imposed by the  jurisdiction in which such Bank's  principal  executive
         office or Eurodollar Office is located); or

                  (B)  shall  impose,  modify  or deem  applicable  any  reserve
         (including  any reserve  imposed by the FRB, but  excluding any reserve
         included in the determination of interest rates pursuant to Section 4),
         special deposit or similar requirement against assets of, deposits with
         or for  the  account  of,  or  credit  extended  by any  Bank  (or  any
         Eurodollar Office of such Bank); or

                  (C) shall  impose on any Bank (or its  Eurodollar  Office) any
         other  condition  affecting  its  Eurodollar  Loans,  its  Notes or its
         obligation to make Eurodollar Loans;

and the result of any of the  foregoing  is to increase  the cost to (or, in the
case of  Regulation  D of the  FRB,  to  impose  a cost  on)  such  Bank (or any
Eurodollar Office of such Bank) of making or maintaining any Eurodollar Loan, or
to reduce  the amount of any sum  received  or  receivable  by such Bank (or its
Eurodollar Office) under this Agreement or under its Notes with respect thereto,
then within 15 days after demand by such Bank (which demand shall be accompanied
by a  statement  setting  forth  in  reasonable  detail  the  basis  for  and  a
calculation of the amount of such demand,  a copy of which shall be furnished to
the  Agent),  the  applicable  Borrower  shall  pay  directly  to such Bank such
additional  amount or amounts as will  compensate  such Bank for such  increased
cost or such reduction.

         (b) If any Bank shall reasonably determine that, after the date of this
Agreement,  the adoption or phase-in of, or any change in, any  applicable  law,
rule  or  regulation   regarding  capital   adequacy,   or  any  change  in  the
interpretation or administration thereof by any governmental authority,  central
bank or comparable  agency  charged with the  interpretation  or  administration
thereof,  or  compliance  by any Bank (or its  Eurodollar  Office) or any Person
controlling such Bank with any request or directive  regarding  capital adequacy
(whether or not having the force of law) of any such authority,  central bank or
comparable  agency,  has or would have the effect of reducing the rate of return
on such Bank's or such  controlling  Person's  capital as a consequence  of such
Bank's  obligations  hereunder  to a level  below  that  which such Bank or such
controlling Person


                                       29


<PAGE>



could have achieved but for such  adoption,  change or  compliance  (taking into
consideration such Bank's or such controlling  Person's policies with respect to
capital adequacy) by an amount deemed by such Bank or such controlling Person to
be  material,  then from time to time,  within 15 days after demand by such Bank
(which demand shall be  accompanied  by a statement  setting forth in reasonable
detail the basis for and a calculation  of the amount of such demand,  a copy of
which shall be  furnished to the Agent),  the  Borrowers  jointly and  severally
agree to pay to such Bank such  additional  amount or amounts as will compensate
such Bank or such controlling Person for such reduction.

         8.2      Basis for Determining Interest Rate Inadequate or
Unfair.  If with respect to any Interest Period:

                  (a)  deposits in Dollars (in the  applicable  amounts) are not
         being offered to the Agent in the interbank  Eurodollar market for such
         Interest Period,  or the Agent otherwise  reasonably  determines (which
         determination   shall,   absent  demonstrable  error,  be  binding  and
         conclusive on the Borrowers) that by reason of circumstances  affecting
         the interbank  Eurodollar  market adequate and reasonable  means do not
         exist for ascertaining the applicable Eurodollar Rate;

                  (b) Banks having an aggregate Percentage of 30% or more advise
         the Agent that the Eurodollar Rate (Reserve  Adjusted) as determined by
         the Agent will not adequately and fairly reflect the cost to such Banks
         of maintaining  or funding such Loans for such Interest  Period (taking
         into  account  any  amount to which such  Banks may be  entitled  under
         Section  8.1),  or that the making or funding of  Eurodollar  Loans has
         become  impracticable  as a result of an event occurring after the date
         of this Agreement which in the opinion of such Banks materially affects
         such Loans,

then the Agent shall promptly  notify the other parties  thereof and, so long as
such circumstances shall continue,  (i) no Bank shall be under any obligation to
make or convert  into  Eurodollar  Loans and (ii) on the last day of the current
Interest Period for each Eurodollar Loan, such Loan shall, unless then repaid in
full, automatically convert to a Base Rate Loan.

         8.3 Changes in Law Rendering  Eurodollar Loans Unlawful.  If, after the
date of this  Agreement,  any  change in  (including  the  adoption  of any new)
applicable  laws  or  regulations,  or  any  change  in  the  interpretation  of
applicable  laws or regulations by any  governmental  or other  regulatory  body
charged with the  administration  thereof,  should make it (or in the good faith
judgment of any Bank cause a substantial  question as to whether it is) unlawful
for any Bank to make,  maintain or fund Eurodollar  Loans,  then such Bank shall
promptly notify each of the other


                                       30


<PAGE>



parties hereto and, so long as such circumstances shall continue,  (a) such Bank
shall have no  obligation  to make or convert into  Eurodollar  Loans (but shall
make  Base  Rate  Loans  concurrently  with the  making  of or  conversion  into
Eurodollar  Loans by the  Banks  which are not so  affected,  in each case in an
amount equal to such Bank's  Percentage of all  Eurodollar  Loans which would be
made or converted  into at such time in the absence of such  circumstances)  and
(b) on the last day of the current  Interest  Period for each Eurodollar Loan of
such Bank (or,  in any event,  on such  earlier  date as may be  required by the
relevant law, regulation or interpretation),  such Eurodollar Loan shall, unless
then repaid in full,  automatically  convert to a Base Rate Loan. Each Base Rate
Loan made by a Bank which, but for the circumstances  described in the foregoing
sentence,  would  be  a  Eurodollar  Loan  (an  "Affected  Loan")  shall  remain
outstanding  for the same period as the Group of Eurodollar  Loans of which such
Affected Loan would be a part absent such circumstances.

         8.4 Funding Losses. Each Borrower hereby agrees that upon demand by any
Bank (which demand shall be accompanied  by a statement  setting forth the basis
for the  calculations  of the amount  being  claimed,  a copy of which  shall be
furnished to the Agent),  such Borrower will indemnify such Bank against any net
loss or expense which such Bank may sustain or incur  (including any net loss or
expense  incurred by reason of the  liquidation or  reemployment  of deposits or
other funds acquired by such Bank to fund or maintain any Eurodollar  Loan),  as
reasonably determined by such Bank, as a result of (a) any payment or prepayment
or  conversion by such  Borrower of any  Eurodollar  Loan of such Bank on a date
other  than the last day of an  Interest  Period  for such Loan  (including  any
conversion  pursuant  to Section  8.3) or (b) any  failure by such  Borrower  to
borrow  or  convert  any  Loans on a date  specified  therefor  in a  notice  of
borrowing  or  conversion  pursuant to this  Agreement.  For this  purpose,  all
notices  to  the  Agent  pursuant  to  this  Agreement  shall  be  deemed  to be
irrevocable.

         8.5 Right of Banks to Fund through Other Offices.  Each Bank may, if it
so elects, fulfill its commitment as to any Eurodollar Loan by causing a foreign
branch or affiliate of such Bank to make such Loan,  provided that in such event
for the purposes of this  Agreement  such Loan shall be deemed to have been made
by such Bank and the  obligation of the  applicable  Borrower to repay such Loan
shall nevertheless be to such Bank and shall be deemed held by it, to the extent
of such Loan, for the account of such branch or affiliate.

         8.6  Discretion of Banks as to Manner of Funding.  Notwithstanding  any
provision of this Agreement to the contrary, each Bank shall be entitled to fund
and  maintain  its funding of all or any part of its Loans in any manner it sees
fit, it being


                                       31


<PAGE>



understood,  however, that for the purposes of this Agreement all determinations
hereunder  shall be made as if such Bank had actually funded and maintained each
Eurodollar  Loan during each Interest  Period for such Loan through the purchase
of deposits having a maturity  corresponding to such Interest Period and bearing
an interest rate equal to the Eurodollar Rate for such Interest Period.

         8.7 Mitigation of Circumstances; Replacement of Affected Bank. (a) Each
Bank shall promptly  notify the Borrowers and the Agent of any event of which it
has knowledge which will result in, and will use reasonable  commercial  efforts
available  to it (and  not,  in  such  Bank's  good  faith  judgment,  otherwise
disadvantageous to such Bank) to mitigate or avoid, (i) any obligation by either
Borrower to pay any amount pursuant to Section 8.1 or (ii) the occurrence of any
circumstances  of the nature  described in Section 8.2 or 8.3 (and,  if any Bank
has given  notice of any such  event  described  in clause (i) or (ii) above and
thereafter  such event ceases to exist,  such Bank shall  promptly so notify the
Borrowers  and the  Agent).  Without  limiting  the  foregoing,  each  Bank will
designate a different  funding office if such  designation will avoid (or reduce
the cost to the Borrowers  of) any event  described in clause (i) or (ii) of the
preceding  sentence  and such  designation  will not,  in such Bank's good faith
judgment, be otherwise disadvantageous to such Bank.

         (b) At any time any Bank is an Affected  Bank,  the Company may replace
such Affected Bank as a party to this  Agreement  with one or more other bank(s)
or financial  institution(s)  reasonably satisfactory to the Agent, such bank(s)
or  financial  institution(s)  to have  Commitments  in such amounts as shall be
reasonably  satisfactory  to the Agent (and upon notice  from the  Company  such
Affected  Bank shall assign  pursuant to an  Assignment  Agreement,  and without
recourse or warranty, its Commitment, its Loans, its Notes, its participation in
Letters of Credit and all of its other rights and obligations  hereunder to such
replacement bank(s) or other financial institution(s) for a purchase price equal
to the sum of the  principal  amount of the Loans so  assigned,  all accrued and
unpaid  interest  thereon,  its ratable share of all accrued and unpaid  non-use
fees and Letter of Credit  fees,  any  amounts  payable  under  Section 8.4 as a
result of such Bank receiving payment of any Eurodollar Loan prior to the end of
an Interest Period therefor and all other obligations owed to such Affected Bank
hereunder).

         8.8    Conclusiveness   of   Statements;    Survival   of   Provisions.
Determinations  and  statements of any Bank pursuant to Section 8.1, 8.2, 8.3 or

and for which  adequate  reserves  in  accordance  with GAAP shall have been set

Hazardous  Material  to be  released  or  disposed  of on,  under or at any real
property owned, leased or operated by the Company or any Subsidiary, (b) no such

to, treated,  or stored at any locations other than those identified pursuant to

or are reviewing the areas within their business and  operations  which could be
adversely affected by, and have developed or are developing a program to address
on a timely  basis,  the "Year 2000  Problem"  (that is, the risk that  computer
applications used by the Company and its Subsidiaries may be unable to recognize
and perform properly  date-sensitive  functions involving certain dates prior to
and any date after  December 31,  1999).  Based on such review and program,  the
Company  reasonably  believes  that  the  "Year  2000  Problem"  will not have a
Material Adverse Effect.

date of the financial statements described in Section 9.4 or, if later, the date
of the most  recent  financial  statements  delivered  to the Banks  pursuant to
Section  10.1.1 or 10.1.2,  no event has occurred or  condition  exists that has
resulted or is reasonably expected to result in a Material Adverse Effect.

         11.2.2 Confirmatory Certificate. If requested by the Agent or any Bank,
the Agent shall have received (in sufficient counterparts to provide one to each
Bank) a certificate  dated the date of such  requested  Loan or Letter of Credit
and signed by a duly authorized  representative of the Company as to the matters
set out in Section 11.2.1 (it being  understood  that each request by a Borrower
for the making of a Loan or the  issuance of a Letter of Credit  shall be deemed
to  constitute a warranty by such  Borrower  that the  conditions  precedent set
forth in Section 11.2.1 will be satisfied at the time of the making of such Loan
or the issuance of such Letter of Credit), together with such other documents as
the Agent or any Bank may reasonably request in support thereof.

         SECTION 12  EVENTS OF DEFAULT AND THEIR EFFECT.

         12.1 Events of Default. Each of the following shall constitute an Event
of Default under this Agreement:

         12.1.1  Non-Payment of the Loans,  etc. Default in the payment when due
of the principal of any Loan; default,  and continuance thereof for two Business
Days  after  demand  by  the  Issuing  Bank,  in  the  payment  when  due of any
reimbursement  obligation with respect to any Letter of Credit; or default,  and
continuance thereof for five days, in the payment when due of any interest,  fee
or other  amount  payable by either  Borrower  hereunder or under any other Loan
Document.

<PAGE>



         12.1.2  Non-Payment  of Other Debt,  etc. Any default shall occur under
the terms applicable to any Debt of the Company or any Restricted  Subsidiary in
an aggregate  amount (for all Debt so affected)  exceeding  $5,000,000  and such
default  shall (a) consist of the failure to pay such Debt when due  (subject to
any  applicable  grace period),  whether by  acceleration  or otherwise,  or (b)
accelerate the maturity of such Debt or permit the holder or holders thereof, or
any trustee or agent for such  holder or  holders,  to cause such Debt to become
due and payable prior to its expressed maturity.

         12.1.3 Other Material Obligations.  Default in the payment when due, or
in the  performance or observance  of, any material  obligation of, or condition
agreed to by,  the  Company or any  Restricted  Subsidiary  with  respect to any
material  purchase or lease of goods or services (except only to the extent that
the  existence  of any such  default is being  contested  by the Company or such
Restricted  Subsidiary  in  good  faith  and  by  appropriate   proceedings  and
appropriate  reserves  have been made in  respect  of such  default)  if, in the
reasonable  judgment  of  the  Required  Banks,  such  default  has  had,  or is
reasonably likely to have, a Material Adverse Effect.

         12.1.4  Bankruptcy,  Insolvency,  etc.  The  Company or any  Restricted
Subsidiary becomes insolvent or generally fails to pay, or admits in writing its
inability  or refusal to pay,  debts as they  become  due; or the Company or any
Restricted Subsidiary applies for, consents to, or acquiesces in the appointment
of a trustee,  receiver or other  custodian  for the Company or such  Restricted
Subsidiary  or any  property  thereof,  or makes a  general  assignment  for the
benefit  of  creditors;  or, in the  absence  of such  application,  consent  or
acquiescence,  a trustee,  receiver  or other  custodian  is  appointed  for the
Company or any Restricted  Subsidiary or for a substantial  part of the property
of  any  thereof  and is not  discharged  within  60  days;  or any  bankruptcy,
reorganization,  debt  arrangement,  or  other  case  or  proceeding  under  any
bankruptcy or  insolvency  law, or any  dissolution  or  liquidation  proceeding
(except the voluntary  dissolution,  not under any bankruptcy or insolvency law,
of any Restricted  Subsidiary other than Heico Holding), is commenced in respect
of the Company or any Restricted  Subsidiary,  and if such case or proceeding is
not commenced by the Company or such Restricted  Subsidiary,  it is consented to
or acquiesced in by the Company or such Restricted Subsidiary, or remains for 60
days undismissed;  or the Company or any Restricted  Subsidiary takes any action
to authorize, or in furtherance of, any of the foregoing.

         12.1.5 Non-Compliance with Provisions of this Agreement. Failure by the
Company to comply  with or to perform  any  covenant  set forth in Section  10.6
through 10.15,  10.17 or 10.19  (excluding  clause (c) of Section  10.19.2);  or
failure by either


                                       52


<PAGE>



Borrower to comply with or to perform any other provision of this Agreement (and
not  constituting an Event of Default under any of the other  provisions of this
Section 12) and  continuance  of such failure for 30 days after  written  notice
thereof to the Company from the Agent or any Bank.

         12.1.6  Warranties.  Any  warranty  made by either  Borrower  herein is
breached or is false or  misleading  in any material  respect,  or any schedule,
certificate,  financial statement,  report, notice or other writing furnished by
either  Borrower to the Agent or any Bank is false or misleading in any material
respect  on the date as of which the  facts  therein  set  forth  are  stated or
certified.

         12.1.7  Pension Plans.  (i)  Institution of any steps by the Company or
any other Person to terminate a Pension Plan if as a result of such  termination
the Company  could be required to make a  contribution  to such Pension Plan, or
could incur a liability or  obligation  to such Pension  Plan,  of $5,000,000 or
more,  or (ii) a  contribution  failure  occurs with respect to any Pension Plan
sufficient to give rise to a Lien under section 302(f) of ERISA.

         12.1.8  Judgments.   Final  judgments  which  exceed  an  aggregate  of
$5,000,000  (excluding any portion thereof which is covered by insurance so long
as the insurer is reasonably  likely to be able to pay and has accepted a tender
of defense and indemnification  without reservation of rights) shall be rendered
against  the  Company  or any  Restricted  Subsidiary  and  shall  not have been
discharged or vacated or had execution  thereof  stayed pending appeal within 30
days after entry or filing of such judgments.

         12.1.9 Invalidity of Guaranties, etc. Either Guaranty shall cease to be
in full force and effect with respect to any applicable  Guarantor  (except as a
result of a transaction permitted hereunder);  any Guarantor shall fail (subject
to any  applicable  grace  period) to comply with or to perform  any  applicable
provision of either Guaranty;  or any Guarantor (or any Person by, through or on
behalf of such  Guarantor)  shall  contest in any manner the  validity,  binding
nature  or  enforceability  of an  applicable  Guaranty  with  respect  to  such
Guarantor.

         12.1.10   Change  in  Control.   Heico  Holding  shall  fail  to  be  a
Wholly-Owned Restricted Subsidiary;  or Permitted Holders shall fail to directly
or indirectly own and control Equity Interests in the Company which provide such
Permitted Holders with the sole right and power (exercisable  either directly or
indirectly) to elect a majority of the Board of Directors.

         12.2 Effect of Event of Default.  If any Event of Default  described in
Section  12.1.4  shall  occur,  the  Commitments  (if they have not  theretofore
terminated) shall immediately  terminate and the Notes and all other obligations
hereunder  shall  become  immediately  due and payable and each  Borrower  shall
become  immediately  obligated  to deliver to the Agent  cash  collateral  in an
amount equal to the outstanding  face amount of all Letters of Credit issued for
the account of such Borrower, all without presentment, demand, protest or notice
of any kind; and, in the case of any other Event of Default,  the Agent may (and
upon written  request of the Required Banks shall) declare the  Commitments  (if
they have not theretofore  terminated) to be terminated and/or declare all Notes
and all other  obligations  hereunder to be due and payable  and/or  demand that
each  Borrower  immediately  deliver to the Agent cash  collateral  in an amount
equal to the  outstanding  face amount of all  Letters of Credit  issued for the
account  of  such  Borrower,   whereupon  the  Commitments  (if  they  have  not
theretofore  terminated)  shall  immediately  terminate and/or all Notes and all
other obligations hereunder shall become immediately due and payable and/or each
Borrower  shall  immediately  become  obligated  to  deliver  to the Agent  cash
collateral in an amount equal to the face amount of all Letters of Credit issued
for the account of such Borrower,  all without presentment,  demand,  protest or
notice of any kind.  The Agent shall  promptly  advise the Borrowers of any such
declaration,  but  failure  to do  so  shall  not  impair  the  effect  of  such
declaration. Notwithstanding the foregoing, the effect as an Event of Default of
any event  described  in Section  12.1.1 or Section  12.1.4 may be waived by the
written  concurrence of all of the Banks,  and the effect as an Event of Default
of any other  event  described  in this  Section 12 may be waived by the written
concurrence of the Required Banks. Any cash collateral delivered hereunder shall
be held by the Agent  (without  liability  for interest  thereon) and applied to
obligations  arising in  connection  with any drawing  under a Letter of Credit.
After  the  expiration  or  termination  of all  Letters  of  Credit,  such cash
collateral  shall be applied by the Agent to any  remaining  obligations  of the
applicable  Borrower  hereunder or under any other Loan  document and any excess
shall  be  delivered  to the  applicable  Borrower  or as a court  of  competent
jurisdiction may direct.

         SECTION 13  THE AGENT.

         13.1  Appointment  and  Authorization;  "Agent".  (a) Each Bank  hereby
irrevocably  (subject to Section 13.9)  appoints,  designates and authorizes the
Agent to take such action on its behalf under the  provisions of this  Agreement
and each other Loan Document and to exercise such powers and perform such duties
as are  expressly  delegated  to it by the terms of this  Agreement or any other
Loan Document, together with such powers as are reasonably incidental


                                       54


<PAGE>



thereto.  Notwithstanding  any provision to the contrary contained  elsewhere in
this Agreement or any other Loan  Document,  the Agent shall not have any duties
or  responsibilities,  except those  expressly set forth  herein,  nor shall the
Agent have or be deemed to have any fiduciary relationship with any Bank, and no
implied  covenants,   functions,   responsibilities,   duties,   obligations  or
liabilities  shall be read into this  Agreement  or any other Loan  Document  or
otherwise  exist  against the Agent.  Without  limiting  the  generality  of the
foregoing sentence, the use of the term "agent" in this Agreement with reference
to the Agent is not  intended  to connote  any  fiduciary  or other  implied (or
express)  obligation  arising  under  agency  doctrine  of any  applicable  law.
Instead,  such term is used merely as a matter of market custom, and is intended
to create or reflect only an  administrative  relationship  between  independent
contracting parties.

                  (b) The  Issuing  Bank  shall act on behalf of the Banks  with
respect  to the  Letters  of Credit  issued by it and the  documents  associated
therewith  until  such time and except for so long as the Agent may agree at the
request of the Required Banks to act for the Issuing Bank with respect  thereto;
provided,  however,  that the Issuing  Bank shall have all of the  benefits  and
immunities (i) provided to the Agent in this Section 13 with respect to any acts
taken or  omissions  of the Issuing  Bank in  connection  with Letters of Credit
issued  by  it  or  proposed  to be  issued  by it  and  the  Letter  of  Credit
Applications  as fully  as if the  term  "Agent",  as used in this  Section  13,
included the Issuing Bank with  respect to such acts or  omissions,  and (ii) as
additionally provided in this Agreement with respect to the Issuing Bank.

         13.2  Delegation  of Duties.  The Agent may  execute  any of its duties
under this Agreement or any other Loan Document by or through agents,  employees
or  attorneys-in-fact  and shall be entitled to advice of counsel concerning all
matters  pertaining to such duties.  The Agent shall not be responsible  for the
negligence or misconduct of any agent or  attorney-in-fact  that it selects with
reasonable care.

         13.3 Liability of Agent. None of the Agent-Related Persons shall (i) be
liable  for any  action  taken or omitted to be taken by any of them under or in
connection  with this  Agreement or any other Loan Document or the  transactions
contemplated hereby (except for its own gross negligence or willful misconduct),
or (ii) be  responsible  in any  manner  to any of the  Banks  for any  recital,
statement,  representation or warranty made by either Borrower or any Subsidiary
or  Affiliate  of either  Borrower,  or any officer  thereof,  contained in this
Agreement  or in  any  other  Loan  Document,  or in  any  certificate,  report,
statement or other  document  referred to or provided for in, or received by the
Agent under or in connection with, this Agreement or any other Loan


                                       55


<PAGE>



Document,  or  the  validity,  effectiveness,   genuineness,  enforceability  or
sufficiency of this Agreement or any other Loan Document,  or for any failure of
either  Borrower  or any  other  party  to any  Loan  Document  to  perform  its
obligations hereunder or thereunder.  No Agent-Related Person shall be under any
obligation  to any Bank to  ascertain  or to  inquire  as to the  observance  or
performance  of any of the  agreements  contained  in, or  conditions  of,  this
Agreement or any other Loan  Document,  or to inspect the  properties,  books or
records  of  either  Borrower  or  any  of  their  respective   Subsidiaries  or
Affiliates.

         13.4  Reliance by Agent.  (a) The Agent shall be entitled to rely,  and
shall be fully  protected  in relying,  upon any  writing,  resolution,  notice,
consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone
message,  statement or other document or conversation  believed in good faith by
it to be genuine and correct and to have been signed, sent or made by the proper
Person or Persons,  and upon advice and  statements of legal counsel  (including
counsel to the  Company or Heico  Holding),  independent  accountants  and other
experts  selected by the Agent. The Agent shall be fully justified in failing or
refusing  to take any action  under this  Agreement  or any other Loan  Document
unless it shall first receive such advice or  concurrence  of the Required Banks
as it deems appropriate and, if it so requests, it shall first be indemnified to
its satisfaction by the Banks (unless otherwise agreed, in accordance with their
Percentages)  against any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action. The Agent shall in
all cases be fully protected in acting, or in refraining from acting, under this
Agreement or any other Loan Document in accordance  with a request or consent of
the  Required  Banks and such  request  and any  action  taken or failure to act
pursuant thereto shall be binding upon all of the Banks.

                  (b) For purposes of determining compliance with the conditions
specified in Section 11.1,  each Bank that has executed this Agreement  shall be
deemed to have  consented to,  approved or accepted or to be satisfied with each
document  or other  matter  either  sent by the Agent to such Bank for  consent,
approval,  acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to such Bank.

         13.5 Notice of Default. The Agent shall not be deemed to have knowledge
or notice  of the  occurrence  of any Event of  Default  or  Unmatured  Event of
Default,  except with respect to defaults in the payment of principal,  interest
and fees  required to be paid to the Agent for the account of the Banks,  unless
the Agent shall have received written notice from a Bank or a Borrower referring
to this  Agreement,  describing  such  Event of Default  or  Unmatured  Event of
Default and stating that such


                                       56


<PAGE>



notice is a "notice of default". The Agent will promptly notify the Banks of its
receipt of any such  notice.  The Agent shall take such  action with  respect to
such Event of Default or  Unmatured  Event of Default as may be requested by the
Required Banks; provided,  however, that unless and until the Agent has received
any such  request,  the Agent  may (but  shall  not be  obligated  to) take such
action,  or refrain  from  taking  such  action,  with  respect to such Event of
Default or Unmatured  Event of Default as it shall deem advisable or in the best
interest of the Banks.

         13.6  Credit  Decision.   Each  Bank  acknowledges  that  none  of  the
Agent-Related Persons has made any representation or warranty to it, and that no
act by the Agent  hereinafter  taken,  including  any  review of the  affairs of
either Borrower, shall be deemed to constitute any representation or warranty by
any Agent-Related  Person to any Bank. Each Bank represents to the Agent that it
has,  independently and without reliance upon any Agent-Related Person and based
on such  documents and  information as it has deemed  appropriate,  made its own
appraisal  of  and  investigation  into  the  business,  prospects,  operations,
property,  financial and other condition and  creditworthiness  of the Borrowers
and their  respective  Subsidiaries,  and all applicable  bank  regulatory  laws
relating to the transactions  contemplated  hereby, and made its own decision to
enter into this Agreement and to extend credit to the Borrowers hereunder.  Each
Bank also represents that it will,  independently  and without reliance upon any
Agent-Related  Person and based on such  documents and  information  as it shall
deem  appropriate  at the  time,  continue  to  make  its own  credit  analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents,  and to make such investigations as it deems necessary
to inform itself as to the business, prospects,  operations, property, financial
and other condition and  creditworthiness  of the Borrowers and their respective
Subsidiaries.  Except for notices,  reports and other documents expressly herein
required to be furnished to the Banks by the Agent, the Agent shall not have any
duty or  responsibility to provide any Bank with any credit or other information
concerning the business,  prospects,  operations,  property, financial and other
condition or  creditworthiness  of the Company or any Subsidiary  which may come
into the possession of any of the Agent-Related Persons.

         13.7   Indemnification  of  Agent.  Whether  or  not  the  transactions
contemplated  hereby are consummated,  the Banks shall indemnify upon demand the
Agent-Related  Persons  (to the  extent  not  reimbursed  by or on behalf of the
Borrowers  and without  limiting the  obligation of the Borrowers to do so), pro
rata, from and against any and all Indemnified Liabilities;  provided,  however,
that no Bank shall be liable for the payment to any Agent-Related  Person of any
portion of the Indemnified


                                       57


<PAGE>



Liabilities  resulting  solely from such  Person's  gross  negligence or willful
misconduct.  Without limitation of the foregoing,  each Bank shall reimburse the
Agent upon demand for its ratable share of any costs or  out-of-pocket  expenses
(including  Attorney  Costs)  incurred  by the  Agent  in  connection  with  the
preparation,  execution, delivery,  administration,  modification,  amendment or
enforcement (whether through  negotiations,  legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities  under, this Agreement,
any other Loan Document,  or any document contemplated by or referred to herein,
to the extent that the Agent is not reimbursed for such expenses by or on behalf
of the Borrowers. The undertaking in this Section shall survive repayment of the
Loans,  cancellation  of the Notes,  the  termination  of this Agreement and the
resignation or replacement of the Agent.

         13.8 Agent in Individual  Capacity.  BofA and its  Affiliates  may make
loans to,  issue  letters of credit for the account of,  accept  deposits  from,
acquire equity interests in and generally engage in any kind of banking,  trust,
financial advisory,  underwriting or other business with the Borrowers and their
respective  Subsidiaries  and  Affiliates  as  though  BofA  were not the  Agent
hereunder and without notice to or consent of the Banks.  The Banks  acknowledge
that,  pursuant  to  such  activities,   BofA  or  its  Affiliates  may  receive
information   regarding  either  Borrower  or  its  Subsidiaries  or  Affiliates
(including  information  that may be subject to  confidentiality  obligations in
favor of the applicable entity) and acknowledge that the Agent shall be under no
obligation to provide such information to them. With respect to its Loans,  BofA
and any  Affiliate  thereof  shall have the same  rights  and powers  under this
Agreement  as any other Bank and may  exercise  the same as though BofA were not
the Agent.

         13.9 Successor Agent. The Agent may, and at the request of the Required
Banks shall,  resign as Agent upon 30 days' written  notice to the Borrowers and
the Banks. If the Agent resigns under this  Agreement,  the Required Banks shall
appoint  from among the Banks a successor  agent for the Banks.  If no successor
agent is appointed  prior to the effective date of the resignation of the Agent,
the Agent may appoint,  after  consulting  with the Banks and the  Borrowers,  a
successor agent from among the Banks.  Upon the acceptance of its appointment as
successor agent hereunder, such successor agent shall succeed to all the rights,
powers and duties of the  retiring  Agent and the term  "Agent"  shall mean such
successor agent and the retiring Agent's appointment, powers and duties as Agent
shall be terminated.  After any retiring Agent's resignation hereunder as Agent,
the provisions of this Section 13 and Sections 14.6 and 14.13 shall inure to its
benefit as to any actions  taken or omitted to be taken by it while it was Agent
under this Agreement. If no successor agent has accepted appointment as Agent by
the date which is 30 days following a


                                       58


<PAGE>



retiring Agent's notice of resignation,  the retiring Agent's  resignation shall
nevertheless  thereupon  become effective and the Banks shall perform all of the
duties of the Agent  hereunder  until such time,  if any, as the Required  Banks
appoint a successor agent as provided for above.  Notwithstanding the foregoing,
BofA shall not be  obligated  to resign as Agent at the request of the  Required
Banks  unless BofA is  replaced  as the  "Issuing  Bank"  hereunder  pursuant to
documentation in form and substance satisfactory to BofA.

         13.10  Withholding  Tax.  (a) If any  Bank is a  "foreign  corporation,
partnership  or trust"  within  the  meaning  of the Code and such  Bank  claims
exemption  from, or a reduction of, U.S.  withholding tax under Sections 1441 or
1442 of the Code,  such Bank agrees,  with and in favor of the Agent, to deliver
to the Borrowers and the Agent:

                  (i) if such Bank claims an exemption  from, or a reduction of,
         withholding  tax under a United States tax treaty,  properly  completed
         IRS Forms 1001 and W-8 before the payment of any  interest in the first
         calendar  year and before the  payment  of any  interest  in each third
         succeeding  calendar year during which  interest may be paid under this
         Agreement;

                  (ii) if  such  Bank  claims  that  interest  paid  under  this
         Agreement is exempt from United  States  withholding  tax because it is
         effectively  connected  with a United  States trade or business of such
         Bank,  two  properly  completed  and  executed  copies of IRS Form 4224
         before the payment of any interest is due in the first  taxable year of
         such Bank and in each succeeding taxable year of such Bank during which
         interest may be paid under this Agreement, and IRS Form W-9; and

                  (iii) such other  form or forms as may be  required  under the
         Code or other laws of the United  States as a  condition  to  exemption
         from, or reduction of, United States withholding tax.

Each such Bank  agrees to  promptly  notify the  Borrowers  and the Agent of any
change  in  circumstances  which  would  modify or render  invalid  any  claimed
exemption or reduction.

         (b) If any Bank claims exemption from, or reduction of, withholding tax
under a United States tax treaty by providing IRS Form 1001 and such Bank sells,
assigns,  grants a participation  in, or otherwise  transfers all or part of the
obligations  of either  Borrower  to such Bank  hereunder,  such Bank  agrees to
notify  the  Agent  of the  percentage  amount  in  which  it is no  longer  the
beneficial owner of such obligations. To the extent


                                       59


<PAGE>



of such percentage  amount, the Agent will treat such Bank's IRS Form 1001 as no
longer valid.

         (c) If any Bank claiming  exemption from United States  withholding tax
by filing IRS Form 4224 with the Agent sells,  assigns,  grants a  participation
in, or otherwise  transfers all or part of the obligations of either Borrower to
such Bank  hereunder,  such Bank agrees to  undertake  sole  responsibility  for
complying with the  withholding  tax  requirements  imposed by Sections 1441 and
1442 of the Code.

         (d)  If  any  Bank  is  entitled  to  a  reduction  in  the  applicable
withholding  tax, the Agent may withhold from any interest  payment to such Bank
an amount equivalent to the applicable withholding tax after taking into account
such reduction.  If the forms or other documentation  required by subsection (a)
of this Section are not delivered to the Agent, then the Agent may withhold from
any  interest   payment  to  such  Bank  not  providing   such  forms  or  other
documentation an amount equivalent to the applicable withholding tax.

         (e) If the Internal Revenue Service or any other governmental authority
of the United  States or any other  jurisdiction  asserts a claim that the Agent
did not  properly  withhold  tax from  amounts paid to or for the account of any
Bank  (because  the  appropriate  form  was not  delivered  or was not  properly
executed,  or  because  such  Bank  failed  to  notify  the Agent of a change in
circumstances  which rendered the exemption  from, or reduction of,  withholding
tax ineffective,  or for any other reason),  such Bank shall indemnify the Agent
fully for all  amounts  paid,  directly  or  indirectly,  by the Agent as tax or
otherwise,  including penalties and interest, and including any taxes imposed by
any  jurisdiction  on the  amounts  payable  to the Agent  under  this  Section,
together with all costs and expenses (including Attorney Costs). The obligations
of the Banks  under  this  subsection  shall  survive  repayment  of the  Loans,
cancellation of the Notes, the termination of this Agreement and the resignation
or replacement of the Agent.

         13.11  Co-Agents.  None of the Banks  identified  on the facing page of
this  Agreement  as a  "Co-Agent"  shall  have  any  right,  power,  obligation,
liability,  responsibility  or  duty  under  this  Agreement  other  than  those
applicable to all Banks as such.  Without  limiting the  foregoing,  none of the
Banks  so  identified  as a  "Co-Agent"  shall  have or be  deemed  to have  any
fiduciary  relationship  with any Bank. Each Bank  acknowledges  that it has not
relied,  and will not rely,  on any of the Banks so  identified  in  deciding to
enter into this Agreement or in taking or not taking action hereunder.

         SECTION 14  GENERAL.

         14.1 Waiver;  Amendments. No delay on the part of the Agent or any Bank
in the exercise of any right, power or remedy shall operate as a waiver thereof,
nor shall any single or partial  exercise by any of them of any right,  power or
remedy preclude other or further exercise thereof,  or the exercise of any other
right, power or remedy. No amendment, modification or waiver of, or consent with
respect to, any  provision of this  Agreement or the Notes shall in any event be
effective  unless the same shall be in writing and signed and delivered by Banks
having  an  aggregate  Percentage  of not  less  than the  aggregate  Percentage
expressly  designated  herein  with  respect  thereto or, in the absence of such
designation as to any provision of this Agreement or the Notes,  by the Required
Banks,  and then any such  amendment,  modification,  waiver or consent shall be
effective only in the specific  instance and for the specific  purpose for which
given.  No  amendment,  modification,  waiver or  consent  shall  (i)  extend or
increase the amount of the Commitments,  (ii) extend the date for payment of any
principal  of or  interest  on the Loans or any fees  payable  hereunder,  (iii)
reduce the  principal  amount of any Loan,  the rate of interest  thereon or any
fees payable  hereunder,  (iv) subject to Section 14.7,  release any Person from
its  obligations  under either  Guaranty or (v) change the aggregate  Percentage
required to effect an amendment,  modification,  waiver or consent  without,  in
each  case,  the  consent  of all Banks.  No  provisions  of Section 13 shall be
amended,  modified or waived  without the  consent of the Agent.  No  amendment,
modification  or waiver of, or consent  with  respect to, any  provision of this
Agreement  affecting the rights or duties of the Issuing Bank shall be effective
without the consent of the Issuing Bank.

         14.2  Confirmations.  Each  Borrower  and each holder of a Note of such
Borrower agree from time to time, upon written  request  received by it from the
other, to confirm to the other in writing (with a copy of each such confirmation
to  the  Agent)  the  aggregate  unpaid  principal  amount  of  the  Loans  then
outstanding under such Note.

         14.3 Notices. Except as otherwise provided in Sections 2.3 and 2.4, all
notices  hereunder shall be in writing  (including  facsimile  transmission) and
shall be sent to the  applicable  party at its address shown below its signature
hereto or at such other address as such party may, by written notice received by
the other  parties  hereto,  have  designated  as its address for such  purpose.
Notices sent by facsimile  transmission  shall be deemed to have been given when
sent;  notices  sent by mail shall be deemed to have been given  three  Business
Days after the date when sent by registered or certified mail,  postage prepaid;
and  notices  sent by hand  delivery  shall be deemed to have  been  given  when
received. For purposes of Sections 2.3 and 2.4, the Agent


                                       61


<PAGE>



shall be entitled to rely on  telephonic  instructions  from any person that the
Agent in good faith believes is an authorized officer or employee of a Borrower,
and each  Borrower  shall hold the Agent and each Bank  harmless  from any loss,
cost or expense resulting from any such reliance.  Any notice received or deemed
received by either Borrower shall be conclusively presumed to have been received
by both Borrowers.

         14.4 Confidentiality. The Agent and the Banks shall hold all non-public
information  obtained  pursuant to the  requirements of this Agreement which has
been  identified  as such by the Borrowers in  accordance  with their  customary
procedures  for  handling  confidential   information  of  this  nature  and  in
accordance  with safe and sound banking  practices  and, in any event,  may make
disclosure  on the  same  confidential  basis as  provided  for  herein  that is
reasonably  required  by  any  actual  or  bona  fide  potential  transferee  or
participant  in  connection  with the  contemplated  transfer of any Note or any
participation  therein or in any Letter of Credit or as required or requested by
any governmental agency or representative  thereof or pursuant to legal process;
provided that, unless specifically  prohibited by applicable law or court order,
each of the Agent and each Bank shall promptly notify the applicable Borrower of
any request by any governmental agency or representative thereof (other than any
such request in connection with an examination of the financial condition of the
Agent or such  Bank by such  governmental  agency)  for  disclosure  of any such
non-public information prior to disclosure of such information.

         14.5  Regulation U. Each Bank  represents  that it in good faith is not
relying,  either  directly or  indirectly,  upon any Margin Stock as  collateral
security for the extension or  maintenance  by it of any credit  provided for in
this Agreement.

         14.6 Costs,  Expenses and Taxes.  The  Borrowers  jointly and severally
agree to pay on demand (a) all  reasonable  out-of-pocket  costs and expenses of
the  Agent  (including  Attorney  Costs)  in  connection  with the  preparation,
execution,  delivery  and  administration  of this  Agreement,  the  other  Loan
Documents  and all other  documents  provided  for herein or  delivered or to be
delivered   hereunder  or  in  connection  herewith  (including  any  amendment,
supplement or waiver to any Loan Document), and (b) all reasonable out-of-pocket
costs and expenses  (including  Attorney  Costs)  incurred by the Agent and each
Bank  after an Event of  Default  in  connection  with the  enforcement  of this
Agreement,  the other  Loan  Documents  or any such other  documents.  Each Bank
agrees to  reimburse  the Agent for such  Bank's  pro rata  share  (based on its
respective  Percentage)  of any such costs and expenses of the Agent not paid by
the Borrowers.  In addition,  the Borrowers  jointly and severally agree to pay,
and to save the Agent and the Banks  harmless from all liability  for, any stamp
or


                                       62


<PAGE>



other taxes which may be payable in  connection  with the execution and delivery
of this Agreement,  the borrowings  hereunder,  the issuance of the Notes or the
execution and delivery of any other Loan Document or any other document provided
for herein or delivered or to be delivered hereunder or in connection  herewith.
All obligations provided for in this Section 14.6 shall survive repayment of the
Loans, cancellation of the Notes and any termination of this Agreement.

         14.7  Designation  of Restricted  and  Unrestricted  Subsidiaries.  The
Company may from time to time (and shall upon the acquisition or creation of any
Subsidiary)   designate  any  Subsidiary  as  a  Restricted   Subsidiary  or  an
Unrestricted  Subsidiary;  provided that (a) no Subsidiary that is not primarily
engaged in  manufacturing,  construction  or  another  industrial  business  and
related  activities  may be  designated  as a  Restricted  Subsidiary;  (b)  any
reclassification of a Subsidiary from a Restricted Subsidiary to an Unrestricted
Subsidiary  or vice versa may be made only (i) upon five  Business  Days'  prior
written notice to the Agent and the Banks and (ii) if,  immediately after giving
pro  forma  effect to such  designation,  (x) the  Company  will be in pro forma
compliance  with each of the  financial  covenants set forth in Section 10.6 and
(y) no Event of  Default  or  Unmatured  Event of Default  would  exist;  (c) no
Subsidiary may be designated as an  Unrestricted  Subsidiary if such  Subsidiary
owns any Equity  Interests or Debt of, or owns or holds any Lien on any property
of, the Company or any Restricted Subsidiary; and (d) Heico Holding shall at all
times be a  Restricted  Subsidiary.  Upon any  reclassification  of a Restricted
Subsidiary to an Unrestricted Subsidiary, the Agent shall, upon the request (and
at the  expense) of the  Company or such  Subsidiary,  execute and deliver  such
releases and other  documents as are necessary to release such  Subsidiary  from
its obligations under the Guaranties.

         14.8  Captions.  Section  captions  used  in  this  Agreement  are  for
convenience only and shall not affect the construction of this Agreement.

         14.9     Assignments; Participations.

         14.9.1  Assignments.  Any Bank may, with the prior written  consents of
the Company and the Agent (which consents shall not be  unreasonably  delayed or
withheld),  at any time assign and delegate to one or more  commercial  banks or
other  Persons (any Person to whom such an  assignment  and  delegation is to be
made being  herein  called an  "Assignee"),  all or any  fraction of such Bank's
Loans and Commitment  (which  assignment and delegation  shall be of a constant,
and not a varying,  percentage  of all the  assigning  Bank's  Loans and of such
Bank's  Commitment) in a minimum aggregate amount equal to the lesser of (i) the
sum of


                                       63


<PAGE>



the assigning Bank's remaining Loans and (to the extent not used) Commitment and
(ii) $5,000,000; provided, however, that (a) no assignment and delegation may be
made to any Person if, at the time of such  assignment  and  delegation,  either
Borrower  would be  obligated to pay any greater  amount under  Section 8 to the
Assignee than such Borrower is then obligated to pay to the assigning Bank under
such  Section;  and (b) the Borrower and the Agent shall be entitled to continue
to deal solely and directly with such Bank in  connection  with the interests so
assigned and  delegated to an Assignee  until the date when all of the following
conditions shall have been met:

                  (x) five  Business  Days (or such lesser period of time as the
         Agent and the  assigning  Bank shall  agree)  shall have  passed  after
         written notice of such assignment and delegation, together with payment
         instructions,  addresses and related  information  with respect to such
         Assignee,  shall have been given to the  Company  and the Agent by such
         assigning Bank and the Assignee,

                  (y) the  assigning  Bank and the Assignee  shall have executed
         and  delivered  to the  Company and the Agent an  assignment  agreement
         substantially  in the form of  Exhibit F (an  "Assignment  Agreement"),
         together with any documents required to be delivered thereunder,  which
         Assignment  Agreement  shall have been  accepted by the Company and the
         Agent, and

                  (z) the  assigning  Bank or the  Assignee  shall have paid the
         Agent a processing fee of $2,500.

From and after the date on which the conditions  described  above have been met,
(x) such Assignee  shall be deemed  automatically  to have become a party hereto
and, to the extent that rights and obligations  hereunder have been assigned and
delegated to such Assignee pursuant to such Assignment Agreement, shall have the
rights and obligations of a Bank  hereunder,  and (y) the assigning Bank, to the
extent that rights and obligations hereunder have been assigned and delegated by
it pursuant to such Assignment Agreement, shall be released from its obligations
hereunder.  Within five Business Days after the  effectiveness of any assignment
and  delegation,  the  Borrowers  shall  execute  and  deliver to the Agent (for
delivery to the Assignee and the assigning Bank, as applicable) new Notes in the
principal  amount of the  Assignee's  Commitment  and, if the assigning Bank has
retained a Commitment  hereunder,  replacement  Notes in the principal amount of
the Commitment retained by the assigning Bank (such Notes to be in exchange for,
but not in payment of, the predecessor  Notes held by such assigning Bank). Each
such Note shall be dated the effective  date of such  assignment.  The assigning
Bank shall mark the predecessor Notes "exchanged" and


                                       64


<PAGE>



deliver them to the Company.  Accrued  interest on that part of the  predecessor
Notes being  assigned  shall be paid as provided  in the  Assignment  Agreement.
Accrued  interest  and fees on that  part of the  predecessor  Notes  not  being
assigned shall be paid to the assigning Bank.  Accrued interest and accrued fees
shall be paid at the same time or times provided in the predecessor Notes and in
this Agreement.  Any attempted  assignment and delegation not made in accordance
with this Section 14.9.1 shall be null and void.

         Notwithstanding the foregoing  provisions of this Section 14.9.1 or any
other  provision of this  Agreement,  any Bank may at any time assign all or any
portion  of its  Loans  and its  Notes to a  Federal  Reserve  Bank (but no such
assignment shall release any Bank from any of its obligations hereunder).

         14.9.2  Participations.  Any Bank  may at any time  sell to one or more
commercial banks or other Persons  participating  interests in any Loan owing to
such Bank, the Notes held by such Bank, the Commitment of such Bank or any other
interest of such Bank  hereunder (any Person  purchasing any such  participating
interest being herein called a "Participant").  In the event of a sale by a Bank
of a  participating  interest to a  Participant,  (x) such Bank shall remain the
holder of its Notes for all purposes of this  Agreement,  (y) the  Borrowers and
the  Agent  shall  continue  to deal  solely  and  directly  with  such  Bank in
connection with such Bank's rights and obligations hereunder and (z) all amounts
payable by the  Borrowers  shall be determined as if such Bank had not sold such
participation and shall be paid directly to such Bank. No Participant shall have
any direct or indirect voting rights hereunder except with respect to any of the
events  described in the penultimate  sentence of Section 14.1. Each Bank agrees
to  incorporate   the   requirements   of  the  preceding   sentence  into  each
participation  agreement which such Bank enters into with any  Participant.  The
Borrowers agree that if amounts  outstanding  under this Agreement and the Notes
are due and payable (as a result of acceleration or otherwise), each Participant
shall be deemed to have the right of  setoff  in  respect  of its  participating
interest in amounts  owing under this  Agreement and any Note to the same extent
as if the amount of its  participating  interest were owing  directly to it as a
Bank under this  Agreement;  provided that such right of setoff shall be subject
to the  obligation of each  Participant  to share with the Banks,  and the Banks
agree to share with each Participant,  as provided in Section 7.5. Each Borrower
also agrees that each Participant shall be entitled to the benefits of Section 8
as if it were a Bank  (provided  that no  Participant  shall receive any greater
compensation   pursuant   to  Section  8  than  would  have  been  paid  to  the
participating Bank if no participation had been sold).

         14.10  Governing  Law. This Agreement and each Note shall be a contract
made  under and  governed  by the laws of the State of  Illinois  applicable  to
contracts made and to be fully performed in such State.  Whenever  possible each
provision  of this  Agreement  shall  be  interpreted  in such  manner  as to be
effective and valid under applicable law, but if any provision of this Agreement
shall be prohibited by or invalid under  applicable law, such provision shall be
ineffective  to  the  extent  of  such   prohibition   or  invalidity,   without
invalidating the remainder of such provision or the remaining provisions of this
Agreement.  All  obligations  of the  Borrowers  and rights of the Agent and the
Banks expressed herein or in any other Loan Document shall be in addition to and
not in limitation of those provided by applicable law.

         14.11  Counterparts.  This  Agreement  may be executed in any number of
counterparts  and by the different  parties hereto on separate  counterparts and
each  such  counterpart  shall  be  deemed  to  be an  original,  but  all  such
counterparts  shall  together  constitute but one and the same  Agreement.  When
counterparts  executed by all of the parties  hereto shall have been lodged with
the Agent (or, in the case of any Bank as to which an executed counterpart shall
not have been so lodged,  the Agent shall have received  confirmation  from such
Bank of execution of a counterpart  hereof by such Bank), the Agent shall notify
the Company and each Bank.

         14.12 Successors and Assigns.  This Agreement shall be binding upon the
Borrowers,  the Banks and the Agent and their respective successors and assigns,
and shall inure to the benefit of the Borrowers, the Banks and the Agent and the
permitted successors and assigns of the Banks and the Agent.

         14.13  Indemnification by the Borrowers.

         (a) In consideration of the execution and delivery of this Agreement by
the Agent and the Banks and the  agreement  to extend the  Commitments  provided
hereunder,  the  Borrowers  hereby  jointly and  severally  agree to  indemnify,
exonerate  and  hold  the  Agent-Related  Persons,  each  Bank and each of their
respective  officers,  directors,  employees and agents  (collectively the "Bank
Parties"  and  individually  each a "Bank  Party")  free and  harmless  from and
against any and all actions, claims, judgments, causes of action, suits, losses,
liabilities,   damages,   penalties  and  expenses,   including  Attorney  Costs
(collectively  the "Indemnified  Liabilities"),  incurred by the Bank Parties or
any of them as a result of, or  arising  out of, or  relating  to (i) any tender
offer,  merger,   purchase  of  stock,  purchase  of  assets  or  other  similar
transaction financed or proposed to be financed in whole or in part, directly or
indirectly,  with  the  proceeds  of any of the  Loans  or (ii)  the  execution,
delivery, performance or


                                       66


<PAGE>



enforcement  of this  Agreement  or any other Loan  Document  by any of the Bank
Parties,  except for any such Indemnified Liabilities arising on account of such
Bank Party's bad faith,  gross negligence or willful  misconduct.  If and to the
extent that the foregoing  undertaking may be unenforceable for any reason,  the
Borrowers hereby jointly and severally agree to make the maximum contribution to
the payment and  satisfaction  of each of the Indemnified  Liabilities  which is
permissible  under applicable law. Nothing set forth above shall be construed to
relieve any Bank Party from any obligation it may have under this Agreement.

         (b) Without  limiting the provisions of clause (a) above, the Borrowers
jointly and  severally  agree to reimburse  each Bank Party  against any and all
Indemnified Liabilities which any Bank Party may pay, incur or become subject to
arising out of or relating to the use, handling,  release, emission,  discharge,
transportation,  storage, treatment or disposal of any Hazardous Material at any
real  property  owned or leased by the Company or any  Subsidiary or used by the
Company or any  Subsidiary in its business or  operations,  except to the extent
caused by the acts or omissions of such Bank Party.

         (c) All  obligations  provided for in this Section  14.13 shall survive
repayment of the Loans,  cancellation  of the Notes and any  termination of this
Agreement.

         14.14 Forum Selection and Consent to Jurisdiction. ANY LITIGATION BASED
HEREON,  OR ARISING OUT OF, UNDER OR IN  CONNECTION  WITH THIS  AGREEMENT OR ANY
OTHER LOAN DOCUMENT,  SHALL BE BROUGHT AND MAINTAINED  EXCLUSIVELY IN THE COURTS

WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION
BROUGHT  IN ANY  SUCH  COURT  REFERRED  TO  ABOVE  AND ANY  CLAIM  THAT ANY SUCH
LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT  FORUM. TO THE EXTENT THAT EITHER
BORROWER HAS OR  HEREAFTER  MAY ACQUIRE ANY IMMUNITY  FROM  JURISDICTION  OF ANY
COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR

AGENT AND EACH BANK HEREBY  WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR
PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS  AGREEMENT,  ANY NOTE, ANY
OTHER  LOAN  DOCUMENT  AND ANY  AMENDMENT,  INSTRUMENT,  DOCUMENT  OR  AGREEMENT
DELIVERED  OR WHICH MAY IN THE FUTURE BE  DELIVERED  IN  CONNECTION  HEREWITH OR
THEREWITH OR ARISING FROM ANY BANKING  RELATIONSHIP  EXISTING IN CONNECTION WITH
ANY OF THE  FOREGOING,  AND AGREES THAT ANY SUCH ACTION OR  PROCEEDING  SHALL BE

                  (d)  Section  2(d)  is  hereby  amended  and  restated  in its
entirety to read as follows:

                  "(d) Each of the MBCP Group  shall  execute and deliver to the
