         experiencing any Year 2000 Problem that could reasonably be expected to
         cause a Material  Adverse  Effect.  The Borrower will provide the Agent
         with a quarterly  certificate within 60 days of the end of each quarter
         commencing  with  such  quarter  ending at March  31,  1999  containing

         Material Adverse Effect."

                           "8.03.  Judgment Currency. If any Lender or the Agent
         obtains a judgment  against  the  Borrower  in an Other  Currency,  the
         obligations of the Borrower in respect of any sum adjudged to be due to
         such Lender or the Agent hereunder or under the Revolving  Credit Notes
         (the "Judgment Amount") shall be discharged only to the extent that, on
         the Business Day  following  receipt by such Lender or the Agent of the
         Judgment  Amount in such  Other  Currency,  such  Lender  or Agent,  in
         accordance with normal banking  procedures,  purchases Dollars with the
         Judgment  Amount in such  Other  Currency.  If the amount of Dollars so
         purchased  is less than the  amount of  Dollars  that  could  have been
         purchased  with the  Judgment  Amount on the date or dates the Judgment
         Amount  was  originally  due and  owing  to the  Lenders  or the  Agent
         hereunder or under the Revolving Credit Notes (the "Original Due Date")
         (excluding  the portion of the  Judgment  Amount which has accrued as a
         result of the  failure of the  Borrower to pay the sum  originally  due
         hereunder or under the  Revolving  Credit Notes when it was  originally
         due  hereunder or under the Revolving  Credit Notes) (the "Loss"),  the
         Borrower agrees, to indemnify such Lender or the Agent, as the case may
         be, against the Loss, and if the amount of Dollars so purchased exceeds
         the amount of Dollars that could have been  purchased with the Judgment
         Amount on the  Original  Due Date,  such Lender or the Agent  agrees to
         remit such excess to the Borrower."

subject to the accuracy as of the date hereof of the representations and
warranties herein contained, to the performance by the Borrower of its

                                    ANNEX A

                                   ARTICLE II
                                   THE CREDITS

                  2.01.  Revolving Credit Loans.

                  (a)  Revolving  Credit  Commitments.  Subject to the terms and
conditions and relying upon the representations and warranties herein set forth,
each Lender,  severally  and not jointly,  agrees (such  agreement  being herein
called such Lender's  "Revolving Credit  Commitment") to make loans in either US
Currency or in an Other Currency (the "Revolving  Credit Loans") to the Borrower
at any time or from  time to time on or after  the  date  hereof  and to but not
including the Revolving Credit Maturity Date.

                  Subject to the terms and conditions herein, each Lender agrees
to make Loans to any Subsidiary  Borrower at any time or from time to time on or
after the date hereof and to but not  including the  Revolving  Credit  Maturity
Date. The Loans shall be made to such Subsidiary Borrower upon the completion of
the following conditions:  (i) submit Standard Notice under Section 2.03 hereof,
(ii)  Curtiss-Wright  Corporation  executes and delivers to the Agent a Guaranty
and Suretyship  Agreement in favor of Lenders in the form as attached  hereto as
Exhibit B (the "Guaranty"), and (iii) the obligation of such Subsidiary Borrower
to repay the unpaid principal amount of the Revolving Credit Loans made to it by
each Lender and to pay interest thereon shall be evidenced in part by promissory
notes from such  Subsidiary  Borrower to each Lender in  substantially  the form
attached hereto as Exhibit C (the  "Subsidiary  Borrower  Notes").  In the event
that a Subsidiary  Borrower becomes a Borrower under this Section  2.01(a),  all
references  to "Borrower" in Articles I, II, IV, VI, VII, VIII and X and Section
5.02 shall be deemed to include such Subsidiary Borrower.

                  A Lender shall have no obligation to make any Revolving Credit
Loan to the extent that the aggregate principal amount of such Lender's Pro Rata
share of the total Revolving Credit Extensions of Credit at any time outstanding
would exceed such Lender's  Revolving Credit Committed Amount at such time. Each
Lender's  "Revolving  Credit Committed Amount" at any time shall be equal to the
amount set forth as its "Initial  Revolving Credit  Committed  Amount" below its
name on the signature pages hereof,  as either such amount may have been reduced
under  Section  2.02  hereof at such time,  and  subject to  transfer to another
Lender as provided in Section 10.14 hereof.

                  (b) Nature of Credit. Within the limits of time and amount set
forth in this Section 2.01, and subject to the provisions of this Agreement, the
Borrower may borrow, repay and reborrow Revolving Credit Loans hereunder.

                  (c) Revolving  Credit Notes. The obligation of the Borrower to
repay the unpaid  principal  amount of the Revolving  Credit Loans made to it by
each  Lender  and to pay  interest  thereon  shall be  evidenced  in part by (i)
promissory  notes of the  Borrower,  one to each Lender,  dated the Closing Date
(the "Borrower  Notes") in substantially  the form attached hereto as Exhibit A,
with the blanks appropriately  filled,  payable to the order of such Lender in a
face amount equal to such Lender's Initial Revolving Credit Committed Amount and
(ii) the  Subsidiary  Notes (the  Borrower  Notes and the  Subsidiary  Notes are
collectively the "Revolving Credit Notes").

                  (d) Maturity.  To the extent not due and payable earlier,  the
Revolving Credit Loans shall be due and payable on the Revolving Credit Maturity
Date.

                  (e) Extension of Revolving Credit Maturity Date. The Revolving
Credit  Maturity  Date may be extended  for  successive  one year periods at the
request of the  Borrower  with the  express  consent of each  Lender as provided
below.  Not later  than the date 90 days  prior to each  Anniversary  Date,  the
Borrower  shall,  at its option,  in a written  notice to the Agent  request (an
"Extension  Request") that the Revolving  Credit Maturity Date be extended for a
period  of one  year.  The Agent  shall  promptly  inform  the  Lenders  of such
Extension  Request.  Each Lender that agrees with such  Extension  Request shall
deliver to the Agent its express  written  consent thereto no later than 60 days
prior to such Anniversary  Date. If (i) any Lender notifies the Agent in writing
on or  before  the 60th  day  prior to such  Anniversary  Date  that it will not
consent to such Extension Request or (ii) all of the Lenders have not in writing
expressly  consented to any such Extension  Request as provided in the preceding
sentence,  then the Agent shall so notify the Borrower and the Borrower,  at its
option,  may replace each Lender which has not agreed to such Extension  Request
(a "Nonextending Lender") with another commercial lending institution reasonably
satisfactory to the Agent (a  "Replacement  Lender") by giving notice (not later
than  the  date 30 days  prior  to such  Anniversary  Date)  of the name of such
Replacement  Lender to the Agent.  Unless the Agent shall object to the identity
of such  proposed  Replacement  Lender  prior to the date 20 days  prior to such
Anniversary  Date, upon notice from the Agent,  each  Nonextending  Lender shall
promptly  (but in no event later than such  Anniversary  Date) assign all of its
interests hereunder to such Replacement Lender in accordance with the provisions
of Section  10.14(c)  hereof.  If, prior to such  Anniversary Date some, but not
all, of the Lenders have agreed to such Extension Request, and each Nonextending
Lender has not been  replaced by the  Borrower in  accordance  with the terms of
this Section  2.01(e),  the Revolving  Credit Maturity Date shall be extended in
accordance with such Extension Request; provided,  however, that on the original
Revolving Credit Maturity Date (as such date may have been previously extended),
the Commitment of each  Nonextending  Lender shall be  terminated,  the Borrower
shall  pay to the  Agent  for the  account  of  such  Nonextending  Lender  such
Nonextending  Lender's  Pro Rata share of the  principal  of and interest on all
outstanding   Revolving   Credit  Loans  and  Letter  of  Credit   Reimbursement
Obligations,  and the total  Revolving  Credit  Commitment  shall be irrevocably
reduced by an amount  equal to the  aggregate  Commitments  of all  Nonextending
Lenders.  If all  Lenders  consent to any such  Extension  Request  (or,  if any
Nonextending  Lenders are replaced in accordance with this Section),  then as of
5:00 p.m.  Pittsburgh time on the Anniversary Date the Revolving Credit Maturity
Date shall be deemed to have been extended for, and shall be the date,  one year
after the then effective  Revolving  Credit Maturity Date (as such date may have
been previously extended pursuant to this Section).

                  2.02.  Revolving  Credit  Commitment  Fee;  Reduction  of  the
Revolving Credit Committed Amounts.

                  (a) Revolving Credit Commitment Fee. The Borrower shall pay to
the Agent for the account of each Lender a commitment fee (the "Revolving Credit
Commitment  Fee") equal to 0.25% per annum  (based on a year of 365 or 366 days,
as the case may be, and actual days  elapsed),  for each day from and  including
the date hereof to but not including the Revolving  Credit Maturity Date, on the
amount  (not  less  than  zero)  equal to (i)  such  Lender's  Revolving  Credit
Committed Amount on such day, minus (ii) the Dollar  Equivalent Amount aggregate
principal  amount  of  such  Lender's  Revolving  Credit  Extensions  of  Credit
outstanding on such day. Such Revolving  Credit  Commitment Fee shall be due and
payable  for the  preceding  period  for which such fee has not been paid (x) on
each Regular  Payment Date,  (y) on the date of each  reduction of the Revolving
Credit Committed Amount (whether optional or mandatory) on the amount so reduced
and (z) on the Revolving Credit Maturity Date.

                  (b) Reduction of the Revolving Credit Committed  Amounts.  The
Borrower  may at any time or from  time to time  reduce  Pro Rata the  Revolving
Credit  Committed  Amounts of the Lenders to an aggregate  amount  (which may be
zero) not less than the Dollar  Equivalent  Amount  sum of the unpaid  principal
amount of the Revolving  Credit Loans then outstanding plus the principal amount
of all Revolving  Credit Loans not yet made as to which notice has been given by
the Borrower  under Section 2.03 hereof.  Any reduction of the Revolving  Credit
Committed  Amounts shall be in an aggregate  amount which is a minimum amount of
$5,000,000  and  integral  multiples  of  $500,000  thereof.  Reduction  of  the
Revolving Credit  Committed  Amounts shall be made by providing not less than 30
days' notice  (which notice shall be  irrevocable)  to such effect to the Agent.
After the date  specified in such notice the  Revolving  Credit  Commitment  Fee
shall be calculated upon the Revolving Credit  Committed  Amounts as so reduced.
Upon reduction of the Revolving  Credit  Committed  Amounts to zero,  payment in
full of all Obligations and expiration or termination of all outstanding Letters
of Credit, this Agreement shall be terminated.

                  2.03. Making of Loans.  Whenever the Borrower desires that the
Lenders make Revolving  Credit Loans, the Borrower shall provide Standard Notice
to the Agent setting forth the following information:

                  (a) The  currency,  which  shall be either US  Currency  or an
         Other Currency, in which such Revolving Credit Loans are to be made;

                  (b)      The party making the borrowing thereunder;

                  (c)      The date, which shall be a Business Day, on which 
         such proposed Loans are to be made;

                  (d) The aggregate  principal  amount of such  proposed  Loans,
         which shall be the sum of the principal  amounts  selected  pursuant to
         clause (e) of this Section 2.03;

                  (e) The interest rate Option or Options selected in accordance
         with  Section  2.04(a)  hereof and the  principal  amounts  selected in
         accordance  with  Section  2.04(d)  hereof of the Base Rate Portion and
         each Funding Segment of the CD Rate Portion and the Euro-Rate  Portion,
         as the case may be, of such proposed Loans; and

                  (f) With respect to each such Funding Segment of such proposed
         Loans, the Funding Period to apply to such Funding Segment, selected in
         accordance with Section 2.04(c) hereof.

Standard  Notice having been so provided,  the Agent shall promptly  notify each
Lender of the information  contained  therein and of the amount of such Lender's
Loan. Unless any applicable condition specified in Article V hereof has not been
satisfied,  on the date specified in such Standard Notice each Lender shall make
the  proceeds  of its Loan  available  to the Agent (a) with  respect  to a Loan
denominated in US Currency,  at the Agent's Office,  no later than 12:00 o'clock
Noon,  Pittsburgh time, in funds immediately  available at such Office,  and (b)
with respect to a Loan  denominated in an Other Currency,  at the Agent's London
Office,  no later than 12:00  o'clock Noon,  London time,  in funds  immediately
available  at such  London  Office.  The Agent  will make the funds so  received
available to the Borrower in funds  immediately  available at the Agent's Office
or London Office, as the case may be.

                  2.04.  Interest Rates.

                  (a) Optional Bases of Borrowing.  The unpaid  principal amount
of the Loans  shall  bear  interest  for each day until due on one or more bases
selected by the Borrower  from among the interest  rate Options set forth below.
Subject to the  provisions of this  Agreement the Borrower may select  different
options  to apply  simultaneously  to  different  Portions  of the Loans and may
select different Funding Segments to apply  simultaneously to different parts of
the CD Rate Portion or the Euro-Rate  Portion of the Loans. The aggregate number
of Funding Segments  applicable to the CD Rate Portion and the Euro-Rate Portion
of the Revolving Credit Loans at any time shall not exceed five.

                  (i) Base Rate Option:  A rate per annum (computed on the basis
         of a year of 365 or 366  days,  as the case  may be,  and  actual  days
         elapsed)  for  each day  equal  to the Base  Rate for such day plus the
         Applicable  Margin for such day. The "Base Rate" for any day shall mean
         the  greater of (A) the Prime Rate for such day or (B) 0.625%  plus the
         Federal Funds Effective Rate for such day, such interest rate to change
         automatically  from time to time  effective as of the effective date of
         each change in the Prime Rate or the Federal Funds Effective Rate.

                  (ii) CD Rate Option:  A rate per annum (based on a year of 360
         days and  actual  days  elapsed)  for each day equal to the CD Rate for
         such day plus the Applicable Margin for such day. "CD Rate" for any day
         shall  mean  for  each   Funding   Segment  of  the  CD  Rate   Portion
         corresponding to a proposed or existing CD Rate Funding Period the rate
         per annum determined by the Agent by adding:

                           (A) the rate per  annum  obtained  by  dividing  (the
                  resulting  quotient to be rounded  upward to the nearest 1/100
                  of 1%) (1) the rate of interest  (which  shall be the same for
                  each day in such CD Rate Funding  Period)  determined  in good
                  faith by the Agent in  accordance  with its  usual  procedures
                  (which  determination  shall  be  conclusive  absent  manifest
                  error) to be the average of the secondary  market bid rates at
                  or about 11:00 a.m., Eastern time, on the first day of such CD
                  Rate  Funding  Period by dealers  of  recognized  standing  in
                  negotiable  certificates  of deposit for the  purchase at face
                  value of  negotiable  certificates  of deposit of major  money
                  center banks for delivery on such day in amounts comparable to
                  such Funding Segment and having maturities  comparable to such
                  CD Rate Funding Period by (2) a number equal to 1.00 minus the
                  CD Rate Reserve  Percentage  for such CD Rate  Funding  Period
                  plus

                           (B) the Assessment Rate.

                  The "CD Rate" may also be expressed by the following formula:

                  [average of the secondary market   ]
                  [bid rates determined by the Agent ]
CD Rate =         [per subsection (A)(1)             ] + Assessment Rate
                  [1.00 - CD Rate Reserve Percentage]

                  "CD Rate Reserve  Percentage"  for any day and for any CD Rate
         Funding  Period  shall  mean the  percentage  (expressed  as a decimal,
         rounded upward to the nearest 1/100 of 1%), as determined in good faith
         by the Agent (which  determination  shall be conclusive absent manifest
         error),  which is in effect on such day as  prescribed  by the Board of
         Governors of the Federal Reserve System (or any successor) representing
         the  maximum  reserve   requirement   (including   without   limitation
         supplemental, marginal and emergency reserve requirements) for a member
         bank of such System in respect of nonpersonal  time deposits in Dollars
         in the  United  States  having a  maturity  comparable  to such CD Rate
         Funding Period.  The CD Rate shall be adjusted  automatically as of the
         effective date of each change in the CD Rate Reserve Percentage. The CD
         Rate  Option  shall be  calculated  in  accordance  with the  foregoing
         whether or not any Lender is actually required to hold such reserves in
         connection  with its  funding  hereof  or,  if  required  to hold  such
         reserves,  is  required  to  hold  reserves  at the  "CD  Rate  Reserve
         Percentage" as herein defined.

                  "Assessment  Rate" for any day  shall  mean the rate per annum
         (rounded upward to the nearest 1/100 of 1%) determined in good faith by
         the Agent in accordance with its usual procedures (which  determination
         shall be conclusive  absent  manifest error) to be the maximum rate per
         annum  payable  by a  depository  institution  insured  by the  Federal
         Deposit  Insurance  Corporation  (or any  successor) for such day as an
         assessment  for  insurance  on Dollar time  deposits,  exclusive of any
         credit that is or may be allowed  against such assessment on account of
         assessment payments made or to be made by such depository  institution.
         The CD Rate shall be adjusted automatically as of the effective date of
         each  change  in the  Assessment  Rate.  The CD Rate  Option  shall  be
         calculated in accordance  with the foregoing  whether or not any Lender
         is  actually  required  to pay Federal  Deposit  Insurance  Corporation
         assessments or, if required to pay such assessments, is required to pay
         such assessments at the "Assessment Rate" as herein defined.

                  The Agent shall give prompt  notice to the Borrower and to the
         Lenders of the CD Rate  determined or adjusted in  accordance  with the
         definition  of CD Rate,  which  determination  or  adjustment  shall be
         conclusive absent manifest error.

                  (iii) Euro-Rate  Option:  A rate per annum (based on a year of
         365 days and actual days  elapsed) for each day equal to the  Euro-Rate
         for such day plus the Applicable  Margin for such day.  "Euro-Rate" for
         any day, as used  herein,  shall mean for each  Funding  Segment of the
         Euro-Rate  Portion  corresponding  to a proposed or existing  Euro-Rate
         Funding  Period the rate per annum  determined by the Agent by dividing
         (the  resulting  quotient to be rounded  upward to the nearest 1/100 of
         1%) (A) the rate of interest  (which  shall be the same for each day in
         such Euro-Rate Funding Period) determined in good faith by the Agent in
         accordance  with its usual  procedures  (which  determination  shall be
         conclusive  absent  manifest  error) to be the average of the rates per
         annum for deposits in US Currency or any Other Currency, as applicable,
         offered to major money center banks in the London  interbank  market at
         approximately  11:00 a.m.,  London time, two London Business Days prior
         to the first day of such  Euro-Rate  Funding Period for delivery on the
         first day of such  Euro-Rate  Funding  Period in amounts  comparable to
         such Funding Segment and having  maturities  comparable to such Funding
         Period by (B) a number equal to

                  1.00     minus the Euro-Rate Reserve Percentage.

                  The  "Euro-Rate"  may  also  be  expressed  by  the  following
formula:

                      [average of the rates offered to major money ]
                      [center banks in the London interbank market]
Euro-Rate =           [determined by the Agent per subsection (A)  ]
                      [1.00 - Euro-Rate Reserve Percentage       ]

                  "Euro-Rate  Reserve  Percentage"  for any day  shall  mean the
         percentage (expressed as a decimal, rounded upward to the nearest 1/100
         of 1%), as determined  in good faith by the Agent (which  determination
         shall be conclusive absent manifest error),  which is in effect on such
         day as  prescribed  by the Board of  Governors  of the Federal  Reserve
         System (or any successor)  representing the maximum reserve requirement
         (including,  without limitation,  supplemental,  marginal and emergency
         reserve  requirements) with respect to eurocurrency  funding (currently
         referred  to as  "Eurocurrency  liabilities")  of a member bank in such
         System.  The  Euro-Rate  shall  be  adjusted  automatically  as of  the
         effective date of each change in the Euro-Rate Reserve Percentage.  The
         Euro-Rate  Option shall be calculated in accordance  with the foregoing
         whether or not any Lender is  actually  required  to hold  reserves  in
         connection with its  eurocurrency  funding or, if required to hold such
         reserves,  is  required  to hold  reserves  at the  "Euro-Rate  Reserve
         Percentage" as herein defined.

                  The Agent shall give prompt  notice to the Borrower and to the
         Lenders of the Euro-Rate  determined or adjusted in accordance with the
         definition of the Euro-Rate, which determination or adjustment shall be
         conclusive absent manifest error.

                  (iv) As-Offered Rate Option. A rate per annum (computed on the
         basis of a year of 360 days and actual days elapsed) for each day equal
         to the "As-Offered  Rate" for such day. The  "As-Offered  Rate" for any
         day shall mean such rate per annum as may be offered by the  Lenders in
         their  sole  discretion  to the  Borrower  from  December  30,  1998 to
         December 31, 1998 (the  "As-Offered  Funding  Period") for such Funding
         Segment as Lenders  shall  offer in their sole  discretion,  which rate
         shall  remain fixed for the  duration of such  As-Offered  Rate Funding
         Period.  Without limiting the discretion of Lender or the generality of
         the foregoing,  the As-Offered Rate (if offered) shall reflect Lender's
         fully  reserved  cost of funds and  shall  include a margin of at least
         0.625%.

                  (b)  Applicable  Margin.  The  "Applicable  Margin"  for  each
interest rate Option for any day shall mean the percentage set forth below:

                    Interest Rate Option          Applicable Margin
                    Base Rate Option              0
                    CD Rate Option                0.625%
                    Euro Rate Option              0.625%
                    As-Offered                    0

                  (c)  Funding  Periods.  At any time  when the  Borrower  shall
select,  convert to or renew the CD Rate Option or the Euro-Rate Option to apply
to any part of the Loans,  the Borrower  shall  specify one or more periods (the
"Funding  Periods")  during  which each such Option  shall  apply,  such Funding
Periods being as set forth below:

                   Interest Rate Option           Available Funding Periods
                   CD Rate Option 
                                                  30,  60,  90, 180 days or such
                                                  longer   period   as   may  be
                                                  offered by all of the  Lenders
                                                  in their sole  discretion ("CD
                                                  Rate Funding Period"); and
                   Euro-Rate Option 
                                                  One, two, three, six months or
                                                  one year or such longer period
                                                  as  may be  offered  by all of
                                                  the   Lenders  in  their  sole
                                                  discretion ("Euro-Rate Funding
                                                  Period");
                    As-Offered
                                                  December  30, 1998 to December
                                                  31, 1998 ("As-Offered  Funding
                                                  Period");
provided, that:

                  (i) Each CD Rate Funding Period which would otherwise end on a
         day  which  is not a  Business  Day  shall  be  extended  to  the  next
         succeeding Business Day;

                  (ii) Each  Euro-Rate  Funding  Period  shall begin on a London
         Business  Day, and the term  "month",  when used in  connection  with a
         Euro-Rate  Funding  Period,  shall  be  construed  in  accordance  with
         prevailing   practices  in  the  interbank  eurodollar  market  at  the
         commencement of such Euro-Rate  Funding  Period,  as determined in good
         faith by the Agent (which determination shall be conclusive);

                  (iii)  The Borrower may not select a Funding Period that would
         end after the Revolving Credit Maturity Date; and

                  (iv) The  Borrower  shall,  in selecting  any Funding  Period,
         allow  for  scheduled  mandatory  payments  and  foreseeable  mandatory
         prepayments of the Loans.

                  (d)  Transactional  Amounts.  Every  selection of,  conversion
from,  conversion  to or renewal of an interest rate Option and every payment or
prepayment  of any Loans shall be in a principal  amount such that after  giving
effect  thereto the aggregate  principal  amount of the Base Rate Portion of the
Revolving  Credit  Loans,  or the  aggregate  principal  amount of each  Funding
Segment of the CD Rate Portion or the Euro-Rate  Portion of the Revolving Credit
Loans, shall be as set forth below:

- --------------------------------- ---------------------------------------------
Portion or Funding Segment        Allowable Aggregate Principal Amounts
- --------------------------------- --------------- -----------------------------
- --------------------------------- ---------------------------------------------
Base Rate Portion                 an integral multiple of 500,000 of US Currency

                                  Borrower
- --------------------------------- ---------------------------------------------

                  (e)    CD Rate or Euro-Rate Unascertainable; Impracticability.
If

                  (i) on any  date  on  which a CD  Rate  or a  Euro-Rate  would
         otherwise be set the Agent (in the case of clauses (A) or (B) below) or
         any Lender (in the case of clause (C) below) shall have  determined  in
         good faith (which  determination  shall be conclusive  absent  manifest
         error) that:

                           (A) adequate and reasonable means do not exist for 
                  ascertaining such CD Rate or Euro-Rate,

                           (B) a contingency  has occurred which  materially and
                  adversely   affects  the  secondary   market  for   negotiable
                  certificates  of deposit  maintained  by dealers of recognized
                  standing or the interbank  eurodollar  market, as the case may
                  be, or

                           (C) the  effective  cost to such  Lender of funding a
                  proposed  Funding  Segment  of  the  CD  Rate  Portion  or the
                  Euro-Rate  Portion from a Corresponding  Source of Funds shall
                  exceed  the CD  Rate or the  Euro-Rate,  as the  case  may be,
                  applicable to such Funding Segment, or

                  (ii) at any time any  Lender  shall  have  determined  in good
         faith (which  determination  shall be conclusive absent manifest error)
         that the  making,  maintenance  or  funding  of any part of the CD Rate
         Portion  or the  Euro-Rate  Portion  has  been  made  impracticable  or
         unlawful by compliance by such Lender or a Notional  Euro-Rate  Funding
         Office in good faith with any Law or  guideline  or  interpretation  or
         administration  thereof by any Governmental  Authority charged with the
         interpretation  or  administration  thereof  or  with  any  request  or
         directive of any such Governmental Authority (whether or not having the
         force of law);

then, and in any such event,  the Agent or such Lender,  as the case may be, may
notify the  Borrower of such  determination  (and any Lender  giving such notice
shall  notify the Agent).  Upon such date as shall be  specified  in such notice
(which shall not be earlier than the date such notice is given),  the obligation
of each of the Lenders to allow the Borrower to select,  convert to or renew the
CD Rate Option or Euro-Rate Option, as the case may be, shall be suspended until
the Agent or such  Lender,  as the case may be,  shall have later  notified  the
Borrower  (and any Lender  giving  such  notice  shall  notify the Agent) of the
Agent's or such Lender's  determination in good faith (which determination shall
be conclusive  absent manifest error) that the circumstance  giving rise to such
previous determination no longer exist.

                  If any Lender notifies the Borrower of a  determination  under
subsection  (ii) of this Section  2.04(e),  the CD Rate Portion or the Euro-Rate
Portion, as the case may be, of the Loans of such Lender (the "Affected Lender")
shall  automatically  be  converted  to the  Base  Rate  Option  as of the  date
specified in such notice (and accrued  interest thereon shall be due and payable
on such date).

                  If at the time the  Agent  or a Lender  makes a  determination
under subsection (i) or (ii) of this Section 2.04(e) the Borrower previously has
notified  the Agent  that it wishes to  select,  convert to or renew the CD Rate
Option or the Euro-Rate Option, as the case may be, with respect to any proposed
Loans but such Loans have not yet been made, such  notification  shall be deemed
to provide for  selection  of,  conversion to or renewal of the Base Rate Option
instead of the CD Rate Option or the Euro-Rate  Option, as the case may be, with
respect to such Loans or, in the case of a determination by a Lender, such Loans
of such Lender.

                  2.05.  Conversion or Renewal of Interest Rate Options.

                  (a)  Conversion  or  Renewal.  Subject  to the  provisions  of
Sections  2.09(c)  and  2.10(b)  hereof,  unless an Event of Default  shall have
occurred and be continuing,  the Borrower may convert any part of its Loans from
any  interest  rate  Option or Options to one or more  different  interest  rate
Options  and may renew  the CD Rate  Option  or the  Euro-Rate  Option as to any
Funding Segment of the CD Rate Portion or the Euro-Rate Portion:

                  (i)  At any time with respect to conversion from the Base Rate
         Option; or

                  (ii) At the  expiration of any Funding  Period with respect to
         conversions  from the  As-Offered  Rate Option or  conversions  from or
         renewals of the CD Rate Option or the Euro-Rate Option, as the case may
         be, as to the Funding Segment  corresponding  to such expiring  Funding
         Period.

Whenever  the Borrower  desires to convert or renew any interest  rate Option or
Options,  the Borrower shall provide to the Agent Standard  Notice setting forth
the following information:

                  (w) The date, which shall be a Business Day, on which the 
         proposed conversion or renewal is to be made;

                  (x) The principal  amounts selected in accordance with Section
         2.04(d) hereof of the Base Rate Portion and each Funding Segment of the
         As-Offered Rate Option,  the CD Rate Portion and the Euro-Rate Portion,
         as the case may be, to be converted from or renewed;

                  (y) The interest rate Option or Options selected in accordance
         with  Section  2.04(a)  hereof and the  principal  amounts  selected in
         accordance  with  Section  2.04(d)  hereof of the Base Rate Portion and
         each Funding Segment of the As-Offered Rate Option, the CD Rate Portion
         and the Euro-Rate Portion, as the case may be, to be converted; and

                  (z) With respect to each Funding Segment to be converted to or
         renewed, the Funding Period selected in accordance with Section 2.04(c)
         hereof to apply to such Funding Segment.

Standard  Notice  having  been so  provided,  after the date  specified  in such
Standard  Notice,  interest shall be calculated upon the principal amount of the
Loans as so converted or renewed.  Interest on the principal  amount of any part
of the Loans converted or renewed  (automatically or otherwise) shall be due and
payable on the conversion or renewal date.

                  (b)  Failure to Convert or Renew.  Absent due notice  from the
Borrower of  conversion  or renewal in the  circumstances  described  in Section
2.05(a)(ii) hereof, any part of the As-Offered Rate Portion, the CD Rate Portion
or Euro-Rate  Portion for which such notice is not  received  shall be converted
automatically  to the Base Rate Option on the last day of the  expiring  Funding
Period;  provided,  however,  that  if  any  Euro-Rate  Portion  is in an  Other
Currency,  such portion shall be renewed automatically for one month on the last
day of the expiring Funding Period.

                  2.06. Prepayments Generally.  Whenever the Borrower desires or
is required to prepay any part of its Loans, it shall provide Standard Notice to
the Agent setting forth the following information:

                  (a) The  currency,  which  shall be either US  Currency  or an
         Other Currency, in which such prepayment is to be made;

                  (b) The date, which shall be a Business Day, on which the 
         proposed prepayment is to be made;

                  (c) The total principal amount of such prepayment, which shall
         be the sum of the principal  amounts selected pursuant to clause (c) of
         this Section 2.06; and

                  (d) The principal  amounts selected in accordance with Section
         2.04(d)  hereof of the Base Rate  Portion and each part of each Funding
         Segment of the  As-Offered  Rate  Portion,  the CD Rate Portion and the
         Euro-Rate Portion, as the case may be, to be prepaid.

Standard Notice having been so provided,  on the date specified in such Standard
Notice,  the principal amounts of the Base Rate Portion and each Funding Segment
of the  As-Offered  Rate Option,  the CD Rate Portion and the Euro-Rate  Portion
specified in such notice,  together with interest on each such principal  amount
to such date, shall be due and payable.

                  2.07. Optional Prepayments.  The Borrower shall have the right
at its  option  from time to time to prepay  its Loans in whole or part  without
premium or penalty (subject, however, to Section 2.10(b) hereof):

                  (a) At any time with respect to any part of the Base Rate 
         Portion; or

                  (b) At the  expiration  of any Funding  Period with respect to
         prepayment of the As-Offered  Rate Portion,  the CD Rate Portion or the
         Euro-Rate Portion,  as the case may be, with respect to any part of the
         Funding Segment corresponding to such expiring Funding Period.

Any such prepayment shall be made in accordance with Section 2.06 hereof.

                  2.08.  Interest  Payment  Dates.  Interest  on the  Base  Rate
Portion shall be due and payable on each Regular Payment Date.  Interest on each
Funding  Segment of the As-Offered  Portion shall be due and payable on the last
day of the  corresponding  As-Offered  Funding Period.  Interest on each Funding
Segment of the CD Rate  Portion  shall be due and payable on the last day of the
corresponding  CD Rate  Funding  Period and, if such CD Rate  Funding  Period is
longer  than 90 days,  also every 90th day during such CD Rate  Funding  Period.
Interest  on each  Funding  Segment of the  Euro-Rate  Portion  shall be due and
payable on the last day of the  corresponding  Euro-Rate  Funding Period and, if
such  Euro-Rate  Funding  Period is longer than three  months,  also every third
month during such Funding  Period.  After  maturity of any part of the Loans (by
acceleration or otherwise),  interest on such part of the Loans shall be due and
payable on demand.

                  2.09.  Pro Rata Treatment; Payments Generally.

                  (a) Pro Rata  Treatment.  Each  borrowing and  conversion  and
renewal of interest rate Options  hereunder shall be made, and all payments made
in respect of principal,  interest and Revolving Credit Commitment Fees due from
the Borrower hereunder or under the Notes shall be applied, Pro Rata from and to
each  Lender,  except for payments of interest  involving an Affected  Lender as
provided in Section  2.04(e)  hereof,  payments to a Lender under Sections 2.10,
2.12 or 3.07 hereof and payments to any Issuing Bank pursuant to Section 3.02(b)
hereof.  The  failure of any Lender to make a Loan shall not  relieve  any other
Lender of its obligation to lend hereunder, but neither the Agent nor any Lender
shall be responsible for the failure of any other Lender to make a Loan.

                  (b)  Payments  Generally.  The  parties  agree  that  (i)  all
payments and prepayments of principal,  interest and other amounts in connection
with Loans  denominated in US Currency and all fees shall be made in US Currency
and (ii) all payments of principal, interest and other amounts (other than fees)
in connection  with  Revolving  Credit Loans  denominated  in any Other Currency
shall be made in such Other Currency. All payments and prepayments to be made in
respect of principal,  interest,  fees or other amounts due from the Borrower in
US Currency shall be payable by 12:00 o'clock noon,  Pittsburgh time, on the day
when due  without  presentment,  demand,  protest or notice of any kind,  all of
which are hereby  expressly  waived,  and an action  therefor shall  immediately
accrue.  Except for payments under Sections 2.10 and 10.06,  such payments shall
be made to the Agent at its Office in US Currency in funds immediately available
at such Office without  setoff,  counterclaim  or other deduction of any nature.
All payments and  prepayments to be made in respect of principal,  interest fees
or other amounts due from the Borrower in any Other Currency shall be payable by
12:00  o'clock  noon,  London  time,  on the day when due  without  presentment,
demand, protest or notice of any kind, all of which are hereby expressly waived,
and an action  therefor  shall  immediately  accrue.  Except for payments  under
Sections 2.10 and 10.06,  such payments shall be made to the Agent at its London
Office in such Other  Currency  in funds  immediately  available  at such Office
without setoff,  counterclaim  or other deduction of any nature.  Any payment or
prepayment  received  (i) in US Currency by the Agent or such Lender after 12:00
o'clock Noon,  Pittsburgh time, on any day shall be deemed to have been received
on the next succeeding  Business Day and (ii) in any Other Currency by the agent
or such Lender after 12:00 o'clock noon, London time, on any day shall be deemed
to have been  received  on the next  succeeding  Business  Day.  The Agent shall
distribute to the Lenders all such payments  received by it from the Borrower as
promptly as practicable after receipt by the Agent.

                  (c) Default Interest. To the extent permitted by law, from and
after the date on which an Event of Default shall have occurred  hereunder,  and
so long as such Event of Default continues to exist, principal,  interest, fees,
indemnity,  expenses or any other  amounts due from the  Borrower  hereunder  or
under any other Loan  Document,  shall bear  interest  for each day  (before and
after judgment), payable on demand, at a rate per annum (in each case based on a
year of 360 days and actual days  elapsed)  which for each day shall be equal to
the following:

                  (i) In the case of any part of the  As-Offered  Rate  Portion,
         the CD Rate  Portion or Euro-Rate  Portion of any Loans,  (A) until the
         end of the applicable  then-current  Funding Period at a rate per annum
         2% above the rate otherwise applicable to such part, and (B) thereafter
         in accordance with the following clause (ii); and

                  (ii) In the case of any  other  amount  due from the  Borrower
         hereunder or under any Loan Document,  2% above the  then-current  Base
         Rate Option.

To the extent permitted by law,  interest accrued under this Section 2.09 on any
amount shall compound on a day-by-day  basis,  and hence shall be added daily to
the overdue amount to which such interest relates.

                  2.10.  Additional Compensation in Certain Circumstances.

                  (a) Increased  Costs or Reduced  Return  Resulting From Taxes,
Reserves, Capital Adequacy Requirements,  Expenses, Etc. If any Law or guideline
or interpretation or application  thereof by any Governmental  Authority charged
with the interpretation or administration thereof or compliance with any request
or directive of any Governmental  Authority  (whether or not having the force of
law) now existing or hereafter adopted:

                  (i)  subjects  any Lender or any  Notional  Euro-Rate  Funding
         Office to any tax or changes the basis of taxation with respect to this
         Agreement,  the  Notes,  the  Loans  or  payments  by the  Borrower  of
         principal,  interest,  commitment  fees or other  amounts  due from the
         Borrower  hereunder or under the Notes (except for taxes on the overall
         net income or overall  gross  receipts of such Lender or such  Notional
         Euro-Rate Funding Office imposed by the jurisdictions  (federal,  state
         and local) in which the Lender's principal office or Notional Euro-Rate
         Funding Office is located),

                  (ii)  imposes,  modifies  or  deems  applicable  any  reserve,
         special deposit or similar  requirement  against credits or commitments
         to extend  credit  extended  by,  assets  (funded  or  contingent)  of,
         deposits  with or for the account of, other  acquisitions  of funds by,
         such  Lender or any  Notional  Euro-Rate  Funding  Office  (other  than
         requirements  expressly  included herein in the determination of the CD
         Rate or the Euro-Rate, as the case may be, hereunder),

                  (iii)  imposes,  modifies  or  deems  applicable  any  capital
         adequacy  or  similar   requirement   (A)  against  assets  (funded  or
         contingent) of, or credits or commitments to extend credit extended by,
         any Lender or any Notional  Euro-Rate  Funding Office, or (B) otherwise
         applicable to the  obligations of any Lender or any Notional  Euro-Rate
         Funding Office under this Agreement, or

                  (iv) imposes upon any Lender or any Notional Euro-Rate Funding
         Office any other  condition or expense with respect to this  Agreement,
         the Notes or its  making,  maintenance  or  funding  of any Loan or any
         security therefor,

and the result of any of the  foregoing is to increase  the cost to,  reduce the
income receivable by, or impose any expense  (including loss of margin) upon any
Lender,  any Notional  Euro-Rate  Funding office or, in the case of clause (iii)
hereof,  any Person  controlling a Lender,  with respect to this Agreement,  the
Notes or the making,  maintenance or funding of any Loan (or, in the case of any
capital adequacy or similar requirement, to have the effect of reducing the rate
of  return  on such  Lender's  or  controlling  Person's  capital,  taking  into
consideration  such Lender's or  controlling  Person's  policies with respect to
capital  adequacy)  by an amount  which such Lender  deems to be material  (such
Lender  being deemed for this  purpose to have made,  maintained  or funded each
Funding  Segment  of the CD  Rate  Portion  and  the  Euro-Rate  Portion  from a
Corresponding  Source of Funds),  such  Lender may from time to time  notify the
Borrower  of the amount  determined  in good  faith  (using  any  averaging  and
attribution methods) by such Lender (which determination shall be conclusive) to
be necessary to compensate such Lender or such Notional Euro-Rate Funding Office
for such increase, reduction or imposition. Such amount shall be due and payable
by the  Borrower to such Lender five  Business  Days after such notice is given,
together  with an amount  equal to  interest  on such  amount  from the date two
Business  Days  after  the date  demanded  until  such due date at the Base Rate
Option. A certificate by such Lender as to the amount due and payable under this
Section  2.10(a)  from time to time and the method of  calculating  such  amount
shall be conclusive absent manifest error.

                  (b) Funding Breakage. In addition to all other amounts payable
hereunder,  if and to the extent for any reason any part of any Funding  Segment
of any  As-Offered  Rate  Portion,  CD Rate Portion or Euro-Rate  Portion of the
Loans  becomes  due (by  acceleration  or  otherwise),  or is paid,  prepaid  or
converted  to  another  interest  rate  Option  (whether  or not  such  payment,
prepayment  or  conversion  is mandatory  or  automatic  and whether or not such
payment  or  prepayment  is then  due),  on a day other than the last day of the
corresponding  Funding  Period  (the date such  amount so becomes  due, or is so
paid,  prepaid or converted,  being referred to as the "Funding Breakage Date"),
the  Borrower  shall pay each Lender an amount  ("Funding  Breakage  Indemnity")
determined by such Lender as follows:

                  (i) first,  calculate the following amount:  (A) the principal
         amount of such Funding  Segment of the Loans owing to such Lender which
         so became due, or which was so paid,  prepaid or  converted,  times (B)
         the greater of (x) zero or (y) the rate of interest  applicable to such
         principal  amount on the  Funding  Breakage  Date minus the  Applicable
         Funding Rate as of the Funding  Breakage Date,  times (C) the number of
         days from and including the Funding  Breakage Date to but not including
         the last day of such Funding Period, times (D) 1/360;

                  (ii) the Funding Breakage Indemnity to be paid by the Borrower
         to such Lender shall be the amount equal to the present value as of the
         Funding Breakage Date (discounted at the Applicable  Funding Rate as of
         such Funding  Breakage  Date,  and calculated on the basis of a year of
         365 or 366 days,  as the case may be, and actual  days  elapsed) of the
         amount described in the preceding clause (i) (which amount described in
         the preceding  clause (i) is assumed for purposes of such present value
         calculation to be payable on the last day of the corresponding  Funding
         Period).

For purposes of this Section,  the term "Applicable Funding Rate" shall mean (i)
in the case of any  calculation  of a Funding  Breakage  Indemnity  payment with
respect to a  particular  Funding  Segment for which the  corresponding  Funding
Period was  originally  one year or longer,  the Treasury  Rate, and (ii) in the
case of any calculation of a Funding Breakage  Indemnity payment with respect to
a Funding Segment for which the corresponding Funding Period was originally less
than one year, the Euro-Rate.

                  Such Funding  Breakage  Indemnity  shall be due and payable on
demand, and each Lender shall, upon making such demand,  notify the Agent of the
amount so demanded. In addition, the Borrower shall, on the due date for payment
of any Funding Breakage Indemnity, pay to such Lender an additional amount equal
to interest on such Funding Breakage Indemnity from the Funding Breakage Date to
but not including such due date at the Base Rate Option  applicable to the Loans
(calculated  on the basis of a year of 360 days and actual  days  elapsed).  The
amount payable to each Lender under this Section  2.10(b) shall be determined in
good faith by such Lender,  and such  determination  shall be conclusive  absent
manifest error.

                  2.11.  HLT  Classification.  In the event  that after the date
hereof the Loans  hereunder are classified as a "highly  leveraged  transaction"
(an "HLT Classification") by any Governmental Authority having jurisdiction over
any Lender,  such Lender may in its  discretion  from time to time so notify the
Agent,  and upon  receiving  such notice the Agent shall promptly give notice of
such event to the Borrower, the Issuing Banks and the Lenders. In such event the
parties hereto shall commence  negotiations to agree on revised Revolving Credit
Commitment Fees, interest rates and Applicable Margins hereunder. If the parties
hereto fail to agree on such  matters in their  respective  absolute  discretion
within 60 days of the  notice  given by the Agent  referred  to above,  then the
Required  Lenders  may at any time or from time to time  thereafter  direct  the
Agent  to (a) by ten  Business  Days'  notice  to the  Borrower,  terminate  the
Revolving  Credit  Commitments,  and  the  Revolving  Credit  Commitments  shall
thereupon  terminate,  or (b) by ten  Business  Days'  notice  to the  Borrower,
declare the Obligations,  together with (without  duplication)  accrued interest
thereon, to be, and the Obligations shall thereupon become,  immediately due and
payable without presentment, demand, protest or other notice of any kind, all of
which are hereby waived,  and an action therefor shall immediately  accrue.  The
Lenders  acknowledge  that an HLT  Classification  is not an Event of Default or
Potential Default hereunder.

                  2.12.  Taxes.

                  (a) Payments Net of Taxes.  All payments  made by the Borrower
under this Agreement or any other Loan Document shall be made free and clear of,
and without reduction or withholding for or on account of, any present or future
income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions
or  withholdings,  now or  hereafter  imposed,  levied,  collected,  withheld or
assessed  by any  Governmental  Authority,  and  all  liabilities  with  respect
thereto, excluding

                  (i) in the  case of the  Agent  and  each  Lender,  income  or
         franchise taxes imposed on the Agent or such Lender by the jurisdiction
         under the laws of which the Agent or such  Lender is  organized  or any
         political  subdivision or taxing  authority  thereof or therein or as a
         result of a connection  between such Lender and any jurisdiction  other
         than  a  connection  resulting  solely  from  this  Agreement  and  the
         transactions contemplated hereby, and

                  (ii) in the case of each  Lender,  income or  franchise  taxes
         imposed by any  jurisdiction  in which such  Lender's  lending  offices
         which make or book Loans are located or any  political  subdivision  or
         taxing authority thereof or therein

(all  such  non-excluded  taxes,  levies,   imposts,   deductions,   charges  or
withholdings being hereinafter called "Taxes").  If any Taxes are required to be
withheld or deducted  from any amounts  payable to the Agent or any Lender under
this Agreement or any other Loan  Document,  the Borrower shall pay the relevant
amount of such Taxes and the  amounts  so  payable  to the Agent or such  Lender
shall be increased to the extent  necessary to yield to the Agent or such Lender
(after  payment  of all  Taxes)  interest  or any  such  other  amounts  payable
hereunder  at the rates or in the amounts  specified in this  Agreement  and the
other Loan  Documents.  Whenever any Taxes are paid by the Borrower with respect
to payments made in connection  with this  Agreement or any other Loan Document,
as promptly as possible thereafter, the Borrower shall send to the Agent for its
own account or for the account of such  Lender,  as the case may be, a certified
copy of an original  official  receipt  received by the Borrower showing payment
thereof.

                  (b) Indemnity.  The Borrower hereby  indemnifies the Agent and
each of the  Lenders for the full amount of such Taxes and any present or future
claims,  liabilities or losses with respect to or resulting from any omission to
pay or delay in paying such Taxes (including any incremental Taxes,  interest or
penalties that may become payable by the Agent or such Lender as a result of any
failure to pay such Taxes but excluding any claims,  liabilities  or losses with
respect to or arising from omissions to pay or delays in payment attributable to
the act or omission of the Agent or any Lender),  whether or not such Taxes were
correctly or legally asserted. Such indemnification shall be made within 30 days
from the date such Lender or the Agent, as the case may be, makes written demand
therefor.

                  (c)  Withholding and Backup  Withholding.  Each Lender that is
incorporated  or  organized  under the laws of any  jurisdiction  other than the
United  States or any state  thereof  agrees  that,  on or prior to the date any
payment is due to be made to it hereunder or under any other Loan  Document,  it
will furnish to the Borrower and the Agent

                  (i) two valid, duly completed copies of United States Internal
         Revenue Service Form 4224 or United States  Internal  Revenue Form 1001
         or successor  applicable  form, as the case may be,  certifying in each
         case that such  Lender is  entitled  to  receive  payments  under  this
         Agreement and the other Loan Documents without deduction or withholding
         of any United States federal income taxes and

                  (ii) a valid, duly completed Internal Revenue Service Form W-8
         or W-9 or successor  applicable  form, as the case may be, to establish
         an exemption from United States backup withholding tax.

Each Lender  which so delivers to the Borrower and the Agent a Form 1001 or 4224
and Form W-8 or W-9,  or  successor  applicable  forms  agrees to deliver to the
Borrower and the Agent two further copies of the said Form 1001 or 4224 and Form
W-8 or W-9, or successor applicable forms, or other manner of certification,  as
the case may be, on or before  the date that any such form  expires  or  becomes
obsolete or otherwise is required to be  resubmitted as a condition to obtaining
an  exemption  from  withholding  tax,  or after  the  occurrence  of any  event
requiring a change in the most recent form previously  delivered by it, and such
extensions  or renewals  thereof as may  reasonably be requested by the Borrower
and the  Agent,  certifying  in the case of a Form  1001 or Form  4224 that such
Lender is entitled to receive  payments  under this  Agreement or any other Loan
Document  without  deduction or  withholding of any United States federal income
taxes,  unless in any such  cases an event  (including  any  changes in Law) has
occurred  prior to the  date on  which  any such  delivery  would  otherwise  be
required which renders all such forms  inapplicable  or which would prevent such
Lender from duly  completing and delivering any such letter or form with respect
to it and such Lender  advises the Borrower and the Agent that it is not capable
of receiving  payments  without any  deduction or  withholding  of United States
federal  income  tax,  and in the  case of a Form  W-8 or W-9,  establishing  an
exemption from United States backup withholding tax.

                  2.13.  Funding by Branch, Subsidiary or Affiliate.

                  (a)  Notional  Funding.  Each Lender shall have the right from
time to time, prospectively or retrospectively,  without notice to the Borrower,
to deem any  branch,  subsidiary  or  affiliate  of such  Lender  to have  made,
maintained or funded any part of the Euro-Rate  Portion at any time. Any branch,
subsidiary  or  affiliate  so  deemed  shall be known as a  "Notional  Euro-Rate
Funding office." Such Lender shall deem any part of the Euro-Rate Portion of the
Loans or the funding therefor to have been  transferred to a different  Notional
Euro-Rate  Funding  Office  if such  transfer  would  avoid  or cure an event or
condition  described in Section  2.04(e)(ii) hereof or would lessen compensation
payable  by the  Borrower  under  Section  2.10(a)  hereof,  and if such  Lender
determines in its sole  discretion  that such transfer would be practicable  and
would not have a Material Adverse Effect on such part of the Loans,  such Lender
or any Notional  Euro-Rate Funding office (it being assumed for purposes of such
determination  that each  part of the  Euro-Rate  Portion  is  actually  made or
maintained by or funded through the  corresponding  Notional  Euro-Rate  Funding
Office).  Notional  Euro-Rate  Funding  Offices  may be  selected by such Lender
without regard to such Lender's actual methods of making, maintaining or funding
Loans or any sources of funding actually used by or available to such Lender.

                  (b) Actual Funding. Each Lender shall have the right from time
to time to make or maintain any part of the Euro-Rate Portion by arranging for a
branch,  subsidiary or affiliate of such Lender to make or maintain such part of
the  Euro-Rate  Portion.  Such  Lender  shall  have  the  right  to (i) hold any
applicable Note payable to its order for the benefit and account of such branch,
subsidiary  or  affiliate  or (ii)  request  the  Borrower  to issue one or more
substitute  promissory notes in the principal amount of such Euro-Rate  Portion,
in  substantially  the form  attached  hereto  as  Exhibit  A,  with the  blanks
appropriately filled,  payable to such branch,  subsidiary or affiliate and with
appropriate  changes reflecting that the holder thereof is not obligated to make
any additional  Loans to the Borrower;  provided,  that if a Lender requests the
Borrower to issue one or more  substitute  promissory  notes in accordance  with
clause  (ii)  above,  the  amount  of the  Note  payable  to such  Lender  shall
automatically  be reduced  accordingly.  The Borrower  agrees to comply promptly
with any request under  subsection (ii) of this Section  2.13(b).  If any Lender
causes a branch,  subsidiary  or  affiliate  to make or maintain any part of the
Euro-Rate Portion  hereunder,  all terms and conditions of this Agreement shall,
except where the context clearly requires otherwise,  be applicable to such part
of the  Euro-Rate  Portion and to any note  payable to the order of such branch,
subsidiary  or  affiliate  to the same  extent as if such part of the  Euro-Rate
Portion  were made or  maintained  and such note were a  Revolving  Credit  Note
payable to such Lender's order.

                  2.14. Closing Fee. The Borrower shall pay to the Agent for the
account  of each  Lender  on the  Closing  Date a fee equal to .10 of 1% of each
Lender's Revolving Credit Commitment.

                  2.15.  Multicurrency Payments.

                  (a)      Dollar Equivalent Amounts.

                  (i) Calculation of Dollar Equivalent Amounts. Upon each making
and upon  each  payment  of a  Revolving  Credit  Loan  denominated  in an Other
Currency,  the  Agent  shall  calculate  the  Dollar  Equivalent  Amount of such
Revolving   Credit  Loan,  as  the  case  may  be,  and  shall  provide  written
confirmation to the Lenders.

                  (ii)   Recalculation   of  Dollar   Equivalent   Amounts.   In
determining  the Dollar  Equivalent  Amount of the  aggregate  Revolving  Credit
Extensions  of Credit of the Lenders,  the Agent may use the  respective  Dollar
Equivalent  Amounts for the Revolving  Credit Loans pursuant to paragraph (i) of
this subsection (a), unless such Dollar Equivalent Amount so calculated  exceeds
90% of the Revolving  Credit  Commitment  Amount,  in which case the Agent shall
recalculate  the  Dollar   Equivalent  Amount  of  the  Revolving  Credit  Loans
outstanding no less  frequently  than once each week. The Agent may  recalculate
the  Dollar  Equivalent  Amounts  of  each  of the  Revolving  Credit  Loans  as
frequently  as it  determines to do so in its  discretion,  provided,  that such
recalculation  shall  be made  for all of the  Revolving  Credit  Loans  no less
frequently  than once each week  during any  period  when the  aggregate  Dollar
Equivalent Amount of the aggregate Credit Exposure of the Lenders exceeds 90% of
the Revolving Credit Commitment Amount.

                  (b)  Unavailability.

                  (i) General. Subject to paragraph (ii) of this subsection (b),
if, in the reasonable  judgment of the Agent,  any Other  Currency  ceases to be
available and freely tradable in the London foreign exchange market,  such Other
Currency shall cease to be an Other Currency. The Agent shall give prompt notice
to the Borrower  and the Lenders of such event.  In the event that (A) the Agent
has  determined  that an Other  Currency has ceased to be  available  and freely
tradable in the London foreign  exchange market and (B) the Agent has determined
in good  faith  that such  Other  Currency  is not  otherwise  available  to the
Borrower,  then, on the date any Revolving Credit Loan denominated in such Other
Currency  would  become due under the terms of this  Agreement  (other than as a
result of an optional  prepayment  under Section 2.07 or of the  acceleration of
such Revolving  Credit Loans under Section 8.02),  the Borrower shall repay such
Revolving  Credit  Loans by paying to each Lender an amount in Dollars  equal to
the amount determined in good faith by such Lender (which determination shall be
conclusive  absent manifest  error)  necessary to compensate such Lender for the
principal  of and  accrued  interest  on such  Revolving  Credit  Loans  and any
additional  cost,  expense or loss  incurred  by such Lender as a result of such
Revolving  Credit Loans being repaid in Dollars  (rather than in the denominated
Other Currency).

                  (ii)  European Monetary Union.

                           A.  Definitions.  In this Section 2.15 and Article II

                  which  circumstances  arise  which  (in  the  opinion  of  the
                  Administrative  Agent) have  substantially the same effect and
                  result in substantially  the same consequences as commencement
                  of the third  stage of EMU as  contemplated  by the  Treaty on

                  European  Council for the  introduction  of,  changeover to or
                  operation of a single or unified  European  currency  (whether
                  known   as  the  euro  or   otherwise),   being  in  part  the
                  implementation of the third stage of EMU;

                           "participating member state" means each state so 
                 described in any EMU legislation; and

                           "Treaty on European  Union"  means the Treaty of Rome
                  of March 25, 1957, as amended by the Single  European Act 1986

                  amended from time to time.

                           B.  Effectiveness of Provisions.  The provisions of 
paragraphs  C to G  below  (inclusive)  shall  be  effective  at  and  from  the
commencement of the third stage of EMU, provided, that if and to the extent that
any such provision  relates to any state (or the currency of such state) that is
not a participating  member state on the commencement of the third stage of EMU,
such  provision  shall  become  effective  in  relation  to such  state (and the
currency  of such  state)  at and from the date on which  such  state  becomes a
participating member state.

                           C.       Redenomination and Alternative Currencies.  
Each obligation under this Agreement of a party to this Agreement which has been
denominated in the national currency unit of a participating  member state shall
be  redenominated  into  the  euro  unit in  accordance  with  EMU  legislation,
provided,  that if and to the  extent  that any EMU  legislation  provides  that
following  the  commencement  of the third  stage of EMU an  amount  denominated
either in the euro or in the national  currency unit of a  participating  member
state and payable within that participating member state by crediting an account
of the  creditor  can be paid by the  debtor  either in the euro unit or in that
national currency unit, each party to this Agreement shall be entitled to pay or
repay any such amount either in the euro unit or such national currency unit.

                           D.  Business Days.  With respect to any amount 
denominated or to be  denominated  in the euro or a national  currency unit, any
reference to a "Business  Day" shall be construed as a reference to a day (other
than a Saturday or Sunday) on which  banks are  generally  open for  business in
London and Pittsburgh,  Pennsylvania  and/or such principal  financial center or
centers in such participating  member state or states as the Agent may from time
to time denominate for this purpose.

                           E.  Payments by the Agent Generally.  With respect to
the  payment of any  amount  denominated  in the euro or in a national  currency
unit, the Agent shall not be liable to the Borrower or any of the Lenders in any
way whatsoever for any delay, or the consequences of any delay, in the crediting
to any account of any amount  required by this Agreement to be paid by the Agent
if the  Agent  shall  have  taken all  relevant  steps to  achieve,  on the date
required by this Agreement, the payment of such amount in immediately available,
freely transferable,  cleared funds (in the euro unit or, as the case may be, in
a  national  currency  unit)  to the  account  with  the  bank in the  principal
financial center in the participating member state which the Borrower shall have
specified for such purpose.  In this paragraph E, "all relevant steps" means all
such  steps  as may be  prescribed  from  time  to time  by the  regulations  or
operating procedures of such clearing or settlement system as the Agent may from
time to time determine for the purpose of clearing or settling payments of euro.

                           F.  Rounding and Other Consequential Changes. Without
prejudice and in addition to any method of conversion or rounding  prescribed by
any EMU  legislation  and without  prejudice to the respective  liabilities  for
indebtedness  of the  Borrower to the  Lenders  and the Lenders to the  Borrower
under or pursuant to this Agreement:

                           (i) each  reference  in this  Agreement  to a minimum
         amount (or an integral multiple thereof) in a national currency unit to
         be paid to or by the Agent shall be  replaced  by a  reference  to such
         reasonably  comparable and convenient  amount (or an integral  multiple
         thereof)  in the euro unit as the Agent may from time to time  specify;
         and

                           (ii) except as  expressly  provided  in this  Section
         2.15,  each  provision  of this  Agreement  shall  be  subject  to such
         reasonable  changes of  construction as the Agent may from time to time
         specify to be necessary or appropriate to reflect the  introduction  of
         or changeover to the euro in participating member states.

                           G.  Increased Costs.  The Borrower shall from time to
time,  at the  request  of the Agent,  pay to the Agent for the  account of each
Lender the amount of any cost or increased cost incurred by, or of any reduction
in any amount  payable to or in the  effective  return on its  capital to, or of
interest or other return foregone by, such Lender or any holding company of such
Lender as a result of the  introduction  of,  changeover  to or operation of the
euro in any participating member state.






                 EIGHTH AMENDMENT TO CREDIT AGREEMENT AND WAIVER

                  THIS EIGHTH AMENDMENT TO CREDIT AGREEMENT AND WAIVER, dated as
of  January  26,  1999  (this  "Amendment"),   by  and  between   CURTISS-WRIGHT
CORPORATION, a Delaware corporation (the "Borrower"), the lenders parties hereto
from time to time (the "Lenders",  as defined further below),  the Issuing Banks
referred  to herein (the  "Issuing  Banks") and MELLON  BANK,  N.A.,  a national
banking  association,  as agent for the Lenders and the Issuing Banks  hereunder
(in such capacity, together with its successors in such capacity, the "Agent").

                              W I T N E S S E T H:

                  WHEREAS, the Borrower,  the Lenders, the Issuing Banks and the
Agent are  parties  to a Credit  Agreement,  dated as of  October  29,  1991 (as
amended, the "Credit Agreement"),  pursuant to which the Lenders have made Loans
to the  Borrower  and certain  Issuing  Banks have  issued  Letters of Credit on
behalf of the Borrower and its Subsidiaries; and

                  WHEREAS,  the Borrower,  the Lenders and the Agent are parties
to a Short Term Credit Agreement,  dated as of October 29, 1994 (as amended, the
"Short Term Credit Agreement"), pursuant to which the Lenders have made Loans to
the Borrower; and

                  WHEREAS,  the  Borrower  has  requested  the  Lenders to amend
certain  provisions of the Credit Agreement and to waive certain terms under the
Credit Agreement and the Short Term Credit Agreement; and

                  WHEREAS, the Lenders are willing to amend the Credit Agreement
and to waive certain terms under the Credit  Agreement and the Short Term Credit
Agreement upon the terms and conditions hereinafter set forth; and

                  WHEREAS,  capitalized  terms  used  herein  and not  otherwise
defined shall have the meanings assigned to them in the Credit Agreement;

                  NOW,  THEREFORE,  in  consideration of the premises and of the
mutual covenants herein contained, and intending to be legally bound hereby, the
parties hereto agree as follows:

                  1. Amendments to Credit Agreement.  Section 7.03 of the Credit
Agreement is hereby  amended to  substitute in the fifth line thereof the amount
"$25,000,000" for the amount "$15,250,000".

                  2.  Waiver.  The  Lenders  hereby  consent  to the  Borrower's
deviation  from  compliance  with the  provisions  of Section 7.03 of the Credit
Agreement to the extent,  but only to the extent,  that such deviation  occurred
prior to the date hereof and resulted from the Borrower  permitting its domestic
Subsidiaries  to  create,  incur,  assume,  suffer to exist or have  outstanding
Funded  Indebtedness  which  in the  aggregate  for  all  domestic  Subsidiaries
exceeded   $15,250,000;   provided,   however,  that  at  no  time  such  Funded
Indebtedness  exceeded  $25,000,000.  Any  Event of  Default  under  the  Credit
Agreement  or the Short Term  Credit  Agreement  arising  out of the  Borrower's
deviation  from  Section 7.03 for the reason  described  above prior to the date
hereof is hereby waived.

                  3. Conditions  Precedent.  The effectiveness of this Amendment
is subject to the  accuracy  as of the date  hereof of the  representations  and
warranties  herein  contained,  to  the  performance  by  the  Borrower  of  its
obligations  to be  performed  hereunder on or before the date hereof and to the
satisfaction, on or before January 26, 1999 (the date of such satisfaction being
referred to herein as the "Effective Date"), of the following further conditions
precedent:

                           (a)  Amendment.  Each  Lender  shall have  received a
                  counterpart of this Amendment, duly executed by the Borrower.

                           (b) Representations and Warranties; Events of Default
                  and Potential  Defaults.  The  representations  and warranties
                  contained in Section 4 hereof shall be true and correct on and
                  as of the  Effective  Date with the same effect as though made
                  on and as of such date.  On the  Effective  Date,  no Event of
                  Default and no Potential  Default  shall have  occurred and be
                  continuing or shall exist or shall occur or exist after giving
                  effect to this  Amendment  and the  transactions  contemplated
                  hereby. By execution of this Amendment, the Borrower certifies
                  to  the  Lenders  that  as  of  the  Effective  Date  (a)  the
                  representations  and  warranties set forth in Section 4 hereof
                  are true and  correct  on and as of such  date and (b) on such
                  date no Event of Default or Potential Default has occurred and
                  is  continuing  or exists or will occur or exist after  giving
                  effect to this  Amendment  and the  transactions  contemplated
                  hereby.

                           (c) Opinions of Counsel. On the Effective Date, there
                  shall have been delivered to the Agent written opinions, dated
                  the Effective  Date, of the General Counsel to the Borrower in
                  form and  substance  satisfactory  to the Agent and as to such
                  matters  incident to the transactions  contemplated  hereby as
                  the Agent may reasonably request.

                  4.   Representations  and  Warranties.   The  Borrower  hereby
represents  and warrants to the Agent and the Lenders  that the  representations
and warranties set forth in the Credit Agreement,  as amended by this Amendment,
are true and  correct  on and as of the date  hereof as if made on and as of the
date hereof,  and that no Event of Default or Potential Default has occurred and
is continuing or exists on and as of the date hereof;  provided,  however, that,
for purposes of the foregoing,  all references in the Credit  Agreement to "this
Agreement"  shall be deemed to be  references  to this  Amendment and the Credit
Agreement as amended by this  Amendment.  In addition,  the reference in Section
4.05 of the Credit Agreement to the financial statements of the Borrower and its
consolidated Subsidiaries as of December 31, 1989 and December 31, 1990 shall be
deemed to be a reference  to the  financial  statements  of the Borrower and its
consolidated  Subsidiaries  as of  December  31,  1997 and  December  31,  1998,
respectively, the reference in such Section to the parallel interim consolidated
financial statements for and as of the end of the six months ended June 30, 1991
shall be deemed to be a reference to the parallel interim consolidated financial
statements for and as of the end of the second fiscal quarter of the fiscal year
beginning  January 1, 1998,  and the  references in the last sentence of Section
4.05 of the Credit  Agreement  to June 30, 1991 and  December  31, 1990 shall be

contract  under the laws of the State of New York and for all purposes  shall be
governed by,  construed and enforced in accordance with the laws of the State of
New York, without regard to principles of conflicts of law.

                  8. Counterparts.  This Amendment may be executed in any number
of counterparts  and by the different  parties hereto on separate  counterparts,
each of which,  when so  executed,  shall be deemed  an  original,  but all such
