is  at  least one (1) Business Day prior to the Business Day on which MSI wishes

to  be  paid  as  interest  hereunder,  or  as  fees or other charges under this
Agreement  or  any  other  agreement  with  Agent,  or with respect to any other
Obligation,  become  due, same shall be deemed a request for a Revolving Advance
as  of  the date such payment is due, in the amount required to pay in full such
interest,  fee, charge or Obligation under this Agreement or any other agreement
with  Agent  or  any  of  the  Lenders,  and  such request shall be irrevocable.
Revolving  Advances which are Domestic Rate Loans shall be in minimum amounts of
$500,000  and  additional  increments  of  $100,000.

          (b)  In the event MSI or MSUK desires to obtain a Revolving Advance as
a  LIBOR Rate Loan, MSI or MSUK, as applicable, shall give Agent (at its Summit,

written  notice,  specifying (i) the date of the proposed borrowing (which shall

Rate  Loans  shall be for one or three months and Interest Periods for Revolving
Advances  to  MSUK  shall  be  for three months; provided, if an Interest Period
would  end  on  a  day  that  is  not  a  Business Day, it shall end on the next
succeeding  Business  Day  unless such day falls in the next succeeding calendar
month in which case the Interest Period shall end on the next preceding Business
Day.  No  such LIBOR Rate Loan shall be made available to MSI or MSUK during the
continuance of a Default or an Event of Default. No more than five (5) Revolving
Advances  as  LIBOR  Rate  Loans  may  be  outstanding  at  any  one  time.

          (c)  Each  Interest  Period  of any Revolving Advance which is a LIBOR
Rate  Loan shall commence on the date such LIBOR Rate Loan is made and shall end
on  such  date  as MSI or MSUK may elect as set forth in (b)(iii) above provided
that  the exact length of each Interest Period shall be determined in accordance
with  the  practice  of  the  London  interbank  market for the currency of such
Revolving  Advance  and  no  Interest Period shall end after the last day of the
Expiration  Date  or  the  Term  as  the  case  may  be.

          (d)  MSI  and  MSUK  shall  each  elect  the  initial Interest Periods
applicable to each Revolving Advance which is a LIBOR Rate Loan by its notice of
borrowing given to Agent pursuant to Section 2.2(b) or in the case of MSI by its
notice  of conversion given to Agent pursuant to Section 2.2(e), as the case may
be.  MSI and MSUK shall elect the duration of each succeeding Interest Period by
giving  irrevocable written notice to Agent of such duration not less than three
(3)  Business  Days  prior  to  the last day of the then current Interest Period
applicable  to  such LIBOR Rate Loan. If Agent does not receive timely notice of
the  Interest  Period  elected  by  MSI or MSUK, as applicable: (i) MSI shall be
deemed  to  have  elected  to convert to a Domestic Rate Loan subject to Section
2.2(e)  hereof;  and  (ii)  MSUK shall be deemed to have elected to continue the
LIBOR  Rate  Loan  for  a  similar  Interest  Period.

          (e)  Provided  that  no  Event  of  Default shall have occurred and be
continuing,  MSI  may,  on  the  last  Business Day of the then current Interest
Period  applicable  to  any  outstanding Revolving Advance which is a LIBOR Rate
Loan,  or  on  any Business Day with respect to Domestic Rate Loans, convert any
such  loan  into  a  loan of another type in the same aggregate principal amount
provided that any conversion of a LIBOR Rate Loan shall be made only on the last
Business  Day  of the then current Interest Period applicable to such LIBOR Rate
Loan. If MSI desires to convert a loan, MSI shall give Agent not less than three
(3)  Business Days' prior written notice to convert from a Domestic Rate Loan to
a LIBOR Rate Loan or one (1) Business Day's prior written notice to convert from
a  LIBOR  Rate  Loan  to  a  Domestic  Rate  Loan,  specifying  the date of such
conversion,  the  loans to be converted and if the conversion is from a Domestic
Rate  Loan  to any other type of loan, the duration of the first Interest Period
therefor.  After  giving  effect  to  each  such  conversion, there shall not be
outstanding  more  than five (5) LIBOR Rate Loans or Domestic Rate Loans, in the
aggregate.  No  such  conversion  option  shall exist for any Revolving Advances
under  the  MSUK  Sublimit.

          (f)  At  its  option  and  upon three (3) Business Days' prior written
notice,  MSI  or MSUK may prepay the LIBOR Rate Loans in whole at any time or in
part  from  time  to  time,  without  premium  or penalty (except as hereinafter
provided),  but with accrued interest on the principal being prepaid to the date
of  such  repayment.  MSI  or  MSUK,  as  applicable,  shall specify the date of
prepayment  of  Advances  which  are  LIBOR  Rate  Loans  and the amount of such
prepayment.  In  the event that any prepayment of a LIBOR Rate Loan is made on a

                                       23
<PAGE>
date  other  than the last Business Day of the then current Interest Period with
respect  thereto,  MSI  or  MSUK,  as  applicable,  shall  indemnify each Lender
therefor  in  accordance  with  Section  2.2(g)  hereof.

          (g)  MSI  or MSUK, as applicable, shall indemnify each Lender and hold
each  Lender  harmless from and against any and all losses or expenses that such
Lender may sustain or incur as a consequence of any prepayment, conversion of or
any default by MSI or MSUK in the payment of the principal of or interest on any
LIBOR  Rate  Loan  or  failure  by  MSI  or  MSUK  to complete a borrowing of, a
prepayment  of or conversion of or to a LIBOR Rate Loan after notice thereof has
been  given, including, but not limited to, any interest payable by such Lenders
to  lenders  of funds obtained by it in order to make or maintain its LIBOR Rate
Loans  hereunder. A certificate as to any additional amounts payable pursuant to
the  foregoing  sentence  submitted  by  such  Lender  to  MSI  or MSUK shall be
conclusive  absent  manifest  error.

          (h) Notwithstanding any other provision hereof, if any applicable law,
treaty,  regulation or directive, or any change therein or in the interpretation
or  application  thereof, shall make it unlawful for any Lender (for purposes of
this  subsection  (g), the term "Lender" shall include any Lender and the office
or  branch  where  any Lender or any corporation or bank controlling such Lender
makes  or  maintains  any  LIBOR  Rate Loans) to make or maintain its LIBOR Rate
Loans,  the  obligation of such Lender to make LIBOR Rate Loans hereunder, shall
forthwith  be  canceled  and MSI or MSUK shall, if any affected LIBOR Rate Loans
are  then  outstanding,  promptly  upon request from such Lender, either pay all
such affected LIBOR Rate Loans or in the case of MSI convert such affected LIBOR
Rate  Loans into loans of another type. If any such payment or conversion of any
LIBOR Rate Loan is made on a day that is not the last day of the Interest Period
applicable  to  such  LIBOR  Rate  Loan, MSI or MSUK shall pay such Lender, upon
Lender's  request, such amount or amounts as may be necessary to compensate such
Lender  for  any loss or expense sustained or incurred by such Lender in respect
of  such  LIBOR  Rate  Loan as a result of such payment or conversion, including
(but  not  limited  to)  any interest or other amounts payable by such Lender to
lenders of funds obtained by such Lender in order to make or maintain such LIBOR
Rate  Loan.  A  certificate as to any additional amounts payable pursuant to the
foregoing  sentence  submitted by such Lender to MSI or MSUK shall be conclusive
absent  manifest  error.

          (i)  Each request by MSI or MSUK for a Revolving Advance shall specify
whether  such  Revolving  Advance  is  for  general corporate or working capital
purposes.  If  the purpose of the Revolving Advance shall be to finance in whole
or  in  part  an acquisition by MSI of stock or assets or a merger or other such
transaction  (an "Acquisition Transaction") which is otherwise permitted hereby,
MSI  shall  (i)  provide  to  Agent  copies of all documentation relating to the
Acquisition  Transaction,  (ii)  execute  and  deliver  such  security and other
documentation  as Agent requires so as to create and perfect a security interest
in  the  acquired assets or stock/equity interests, (iii) if the acquired entity
becomes  a  direct  or indirect Subsidiary of MSI, cause such entity to become a
co-borrower  hereunder  or  to  execute  and  deliver  a  Guaranty  and security
agreement  as  required by Agent and (iv) provide such other documents, opinions
and  other  matters  as  Agent  reasonably  requests.

          (j)  All  Revolving  Advances  shall be subject to compliance with the
provisions  of  Section  2.11(c)  hereof at the time of such Revolving Advances.

                                       24
<PAGE>
          (k)  The  provisions of subsections (e), (f), (g) and (h) hereof shall
be  applicable  to Revolving Advances which are LIBOR Rate Loans and to the Term
Loan.

     2.3. DISBURSEMENT  OF  ADVANCE  PROCEEDS.

          All  Advances  shall be disbursed from whichever office or other place
Agent  may  designate  from  time  to  time  (including  the London Branch as to
Revolving  Advances to MSUK) and, together with any and all other Obligations of
MSI  and  MSUK  to Agent and Lenders, shall be charged to Borrowers' Accounts on
Agent's  books. Prior to the Expiration Date, MSI and MSUK may use the Revolving
Advances  by  borrowing,  prepaying  and reborrowing, all in accordance with the
terms and conditions hereof. The proceeds of each Revolving Advance requested by
MSI or MSUK or deemed to have been requested by MSI or MSUK under Section 2.2(a)
hereof shall, with respect to requested Revolving Advances to the extent Lenders
make  such  Revolving  Advances,  be made available to MSI or MSUK on the day so
requested  by way of credit to MSI's or MSUK's, as applicable, operating account
at  the  Agent,  in  immediately  available  federal  funds or other immediately
available  funds  or,  with  respect  to  Revolving Advances deemed to have been
requested  by MSI or MSUK, as applicable, be disbursed to Agent to be applied to
the  outstanding  Obligations  giving  rise  to  such  deemed  request.

     2.4. MAKING  REVOLVING  ADVANCES.

          The  Agent  shall,  promptly  after  receipt  by it of a request for a
Revolving  Advance pursuant to Section 2.2, notify the Lenders of its receipt of
such request specifying: (i) the date of the proposed borrowing and the time and
method  of  disbursement  of  the  Revolving Advance requested thereby; (ii) the
amount  and  type  of  each  such  Revolving Advance and the applicable Interest
Period (if any); and (iii) the apportionment among the Lenders of such Revolving
Advance  as  determined by the Agent in accordance with Section 2.1(c), and (iv)
whether  the  requested Revolving Advance is to be disbursed in Dollars (to MSI)
or  Pounds  Sterling (to MSUK). Each Lender shall remit its Ratable Share of the
principal  amount  of each Revolving Advance to the Agent such that the Agent is
able to, and Agent shall, to the extent the Lenders have made funds available to
it  for  such  purpose,  fund such Revolving Advances to MSI in U.S. Dollars and
immediately  available  funds  and  to  MSUK  in Pounds Sterling and immediately
available  funds  at  the  applicable  Payment Office prior to 2:00 p.m., on the
applicable  borrowing date provided that if any Lender fails to remit such funds
to  the  Agent in a timely manner, the Agent may elect in its sole discretion to
fund  with its own funds the Revolving Advances of such Lender on such borrowing
date,  and  such  Lender shall be subject to the repayment obligation in Section
13.16.  If  any  Lender so notified fails to make available to the Agent for the
account  of  the  Agent  the  amount  of  such Lender's portion of the Revolving
Advance no later than 2:00 p.m., on the applicable borrowing date, then interest
shall  accrue  on  such  Lender's  obligation  to  make  such  payment, from the
applicable  borrowing  date  to the date on which such Lender makes such payment
(1)  with respect to Revolving Advances to MSI: (i) at a rate per annum equal to
the  Federal Funds Rate during the first three (3) days following the applicable
borrowing  date;  and  (ii)  at a rate per annum equal to the rate applicable to
Revolving  Advances  which  are  Domestic Rate Loans on and after the fourth day
following  the  applicable  borrowing  date;  and  (2) with respect to Revolving
Advances  to  MSUK,  at the applicable Revolving Interest Rate, in each case for
such  period(s)  as  selected  by  the  Agent.

                                       25

     2.5. TERM  LOAN.

          Subject to the terms and conditions of the Existing Loan Agreement and
this Agreement, each Lender, severally on a ratable basis in accordance with its
Ratable  Share made a term loan to MSI which when aggregated with the term loans
made  by the other Lenders totals $25,000,000. The Term Loan was advanced by the
Lenders  in  their Ratable Share on the Existing Loan Agreement Closing Date and
is,  with respect to principal, payable as follows, subject to acceleration upon
the  occurrence  of  an  Event of Default under this Agreement or termination of
this  Agreement:

          (a)  Quarterly payments of principal of the Term Loan in the amount of
$1,000,000  each  plus  interest  is  payable  on the first Business Day of each
calendar quarter, commencing on September 1, 2000, and each December 1, March 1,
June  1  and  September  1  thereafter,  provided,  however  that  the last such
installment  shall  be  in  the  amount  necessary  to  repay in full the unpaid
principal  amount  of the Term Loan. All remaining principal amounts outstanding
under  the Term Loan together with all accrued interest thereon shall be due and
payable  in  full  on  the  Term  Loan  Maturity  Date.

          (b) In addition to the Term Loan payment set forth in Section 2.4 (a),
MSI shall pay, as additional principal payments on the Term Loan an amount equal
to  the net proceeds of any sale or issuance of equity of MSI in an amount equal
to  the  greater  of $5,000,000 or 33% of such net proceeds realized from equity
sales  or  issuances  by  MSI.  Amounts  prepaid in accordance with this Section
2.5(b)  shall  be  applied  against  principal  installments of the Term Loan in
inverse  order  of  maturity.  The  Term Loan is evidenced by secured promissory
notes  dated  August 7, 2000 from MSI to each of the Lenders (the "Term Notes").

          (c)  The obligations of each Lender to make the Term Loan to MSI shall
be  in  the proportion that such Lender's Term Loan Commitment bears to the Term
Loan Commitments of all Lenders to MSI, but each Lender's Term Loan to MSI shall
never  exceed its Term Loan Commitment. The failure of any Lender to make a Term
Loan  shall  not relieve any other Lender of its obligations to make a Term Loan
nor  shall it impose any additional liability on any other Lender hereunder. The
Term  Loan  Commitments  are  not revolving credit commitments and MSI shall not
have  the  right  to  borrow,  repay  and  reborrow  under  this  Section  2.5.

          (d)  Interest  Periods  for  the  Term Loan shall be for three months;
provided, if such Interest Period would end on a day that is not a Business Day,
it  shall  end  on the next succeeding Business Day unless such day falls in the
next  succeeding  calendar  month in which case the Interest Period shall end on
the  next  preceding  Business  Day.

     2.6. MAXIMUM  ADVANCES.

          The  aggregate  balance  of Revolving Advances outstanding at any time
shall  not  exceed the lesser of (a) the Maximum Revolving Advance Amount or (b)
the  Formula  Amount.

     2.7. REPAYMENT  OF  ADVANCES.

          (a) The Revolving Advances shall be due and payable by MSI or MSUK, as
the case may be, in full on the Expiration Date subject to earlier prepayment as
herein  provided.  The Term Loan shall be due and payable as provided in Section
2.5  hereof  and  in  the  Term  Note.

                                       26
<PAGE>
          (b)  All  payments  of  principal,  interest and other amounts payable
hereunder,  or  under  any  of the Other Documents shall be made to Agent at the
applicable  Payment Office not later than 2:00 p.m. (New York or London time, as
applicable)  on  the  due  date  therefor  in  Dollars  (as to MSI) or in Pounds
Sterling  (as to MSUK), in each case in federal funds or other funds immediately
available  to Agent. Agent shall have the right to effectuate payment on any and
all  Obligations  due  and owing hereunder by charging Borrowers' Accounts or by
making  Advances  as  provided  in  Section  2.2  hereof.

          (c)  MSI and MSUK shall pay principal, interest, and all other amounts
payable  hereunder,  or  under  any  Other  Documents,  without  any  deduction
whatsoever,  including,  but  not  limited  to,  any deduction for any setoff or
counterclaim.

     2.8. REPAYMENT  OF  EXCESS  ADVANCES.

          The aggregate balance of Advances outstanding at any time in excess of
the  Maximum  Revolving  Advance  Amount  shall  be  immediately due and payable
without  the  necessity  of  any demand, at the Payment Office, whether or not a
Default  or  Event  of  Default  has  occurred.

     2.9. STATEMENT  OF  ACCOUNT.

          Agent  shall  maintain,  in  accordance with its customary procedures,
loan accounts in the name of MSI and MSUK ("Borrowers' Accounts") in which shall
be  recorded  the  date, currency and amount of each Advance made by each Lender
and  the date, currency and amount of each payment in respect thereof; provided,
however,  the  failure  by  Agent  to record the date, currency or amount of any
Advance  shall  not  adversely affect Agent or any Lenders. The records of Agent
with  respect  to  the loan account shall be conclusive evidence absent manifest
error  of  the  amounts  of  Advances  and other charges thereto and of payments
applicable  thereto.

     2.10.  ADDITIONAL  PAYMENTS.

          Any  sums  expended  by  Agent  or  any Lender due to MSI's, MSUK's or
Sensors'  failure to perform or comply with its obligations under this Agreement
or  any  Other  Document  including,  without  limitation,  MSI's  and  MSUK's
obligations  under  Sections  4.2,  4.4, 4.12, 4.13, 4.14 and 6.1 hereof, may be
charged  to  Borrowers'  Accounts  as  Revolving  Advances  and  added  to  the
Obligations.

     2.11.  MANDATORY  PREPAYMENTS.

          (a)  When MSI, MSUK, Sensors or any other Guarantor sells or otherwise
disposes  of  any Collateral or Subsidiary Collateral, as the case may be, other
than  Inventory or collection of Receivables in the ordinary course of business,
MSI  or  MSUK, as applicable, shall, except as otherwise permitted under Section
4.3,  repay  the  Advances  in  an amount equal to the net proceeds of such sale
(i.e.,  gross  proceeds  less  the  reasonable  costs  of  such  sales  or other
dispositions), such repayments to be made promptly but in no event more than one
(1)  Business  Day following receipt of such net proceeds, and until the date of
payment,  such  proceeds  shall  be  held  in  trust  for Agent and Lenders. The
foregoing  shall  not be deemed to be implied consent to any such sale otherwise

                                       27
<PAGE>
prohibited  by the terms and conditions hereof. Such repayments shall be applied
first, ratably to the outstanding principal installments on the Term Loan in the
inverse  order  of the maturities thereof and, second, to the remaining Advances
in  such  order  as  Agent  may determine, subject to MSI's or MSUK's ability to
reborrow  Revolving  Advances  in  accordance  with  the  terms  hereof.

          (b)  Upon  any  issuance of additional equity by MSI, MSI shall prepay
the  outstanding  amount  of the Term Loan in an amount equal to net proceeds of
any  sale  or  issuance  of  equity  of MSI in an amount equal to the greater of
$5,000,000  or  33%  of  such net proceeds of such equity issuance, which amount
shall be applied first, ratably to the outstanding principal installments of the
Term  Loan  in  the  inverse order of the maturities thereof and, second, to the
remaining Advances in such order as Agent determines subject to MSI's and MSUK's
ability  to  reborrow  Revolving  Advances  in accordance with the terms hereof.

          (c)  If  at  the  end  of any Interest Period the sum of the principal
amount  of  Revolving  Advances  outstanding  to  MSI plus all Letters of Credit
Outstanding  plus the principal amount of Revolving Advances outstanding to MSUK
under  the  MSUK  Sublimit  exceeds  the Borrowing Base or the Maximum Revolving
Advance  Amount,  such  excess shall be immediately repaid by MSI and/or MSUK to
Agent. If at the time of any extension of any Revolving Advance, the issuance of
any  Letter  of Credit or at the end of any Interest Period the principal amount
of  Revolving  Advances  outstanding  to MSUK under the MSUK Sublimit (including
Letters  of  Credit  Outstanding  for  the  account  of MSUK) exceeds the Pounds
Sterling  equivalent  of  $3,500,000, such excess shall be immediately repaid by
MSI  and/or  MSUK  to  Agent  and/or  the  amount of any Revolving Advance to be
extended  shall  be  reduced  accordingly.

     2.12.  OPTIONAL  PREPAYMENT.

          MSI  shall have the right, upon three (3) days prior written notice to
the  Agent,  to  prepay  the  Term  Loan,  in  compliance with the terms of this
Agreement, in whole or in part, plus accrued interest to the date of prepayment.
Any  such  prepayment  shall  be  applied  ratably  to the outstanding principal
installments  of  the  Term  Loan in inverse order of maturities thereof. In the
event  that any prepayment of portion of the Term Loan that is a LIBOR Rate Loan
is  required  or  permitted under Sections 2.11 or 2.12 on a date other than the
last Business Day of then current Interest Period with respect hereto, MSI shall
indemnify  each  Lender  therefor  in  accordance  with  Section  2.2(g) hereof.

     2.13.  USE  OF  PROCEEDS.

          MSI  shall  apply  (or  has  applied)  the proceeds of Advances (i) to
restructure  and  continue  its  debt  to  the  Lenders  under the Existing Loan
Agreement,  (ii) to provide for its working capital needs, and (iii) for general
corporate purposes. MSUK shall use the proceeds of the initial Revolving Advance
under  the  MSUK  Sublimit  to  repay  to  MSI the Pounds Sterling equivalent of
$2,500,000,  which  amount shall be applied by MSI against the Intercompany Loan
and  which  amount  shall  then  be repaid by MSI to Agent as a reduction of the
Revolving  Advances.  All  subsequent Revolving Advances under the MSUK Sublimit
shall  be  for  general working capital purposes of MSUK or for the repayment of
all  or  part  of  the  Intercompany  Loan.

     2.14.  LETTER  OF  CREDIT  SUBLIMIT.

          (a)  MSI  or  MSUK may request the issuance of a documentary letter of
credit  or a standby letter of credit (each, a "Letter of Credit") by delivering
to  the  Agent  at its Summit, New Jersey Payment Office a completed application

                                       28
<PAGE>
and  agreement  for letters of credit in such form as the Agent may specify from
time  to  time  by no later than 10:00 a.m., New York time, and in the case of a
Letter  of Credit denominated in Pounds Sterling, by also notifying the Agent at
the  London  Branch  by  no  later than 10:00 a.m., London time, in each case at
least three (3) Business Days, or such shorter period as may be agreed to by the
Agent, in advance of the proposed date of issuance. A Letter of Credit requested
by  MSI shall be in Dollars and a Letter of Credit requested by MSUK shall be in
Pounds  Sterling.  Subject to the terms and conditions hereof and in reliance on
the  agreements  of the Lenders set forth in this Section 2.14, First Union will
issue  a  Letter  of Credit provided that each Letter of Credit shall (A) have a
maximum  maturity of twelve (12) months from the date of issuance, and (B) in no
event  expire later than ten (10) Business Days prior to the Expiration Date and
providing  that  in  no  event  shall  (i)  the face amount of Letters of Credit
Outstanding  exceed, at any one time, $1,000,000, or (ii) the sum of the Letters
of Credit Outstanding plus the outstanding Revolving Advances exceed the Formula
Amount.

          (b)  MSI or MSUK, as applicable, shall pay to the Agent quarterly fees
(the  "Letter  of  Credit Fees") on (i) the average aggregate face amount of all
documentary  Letters  of Credit outstanding during the prior fiscal quarter at a
per  annum rate equal to 1.0%; and (ii) the average aggregate face amount of all
standby  Letters  of Credit outstanding during the prior fiscal quarter at a per
annum  rate  equal  to  2.0%, which fees shall be payable in arrears on the last
Business  Day of each fiscal quarter and on the Expiration Date. One-half of the
Letter of Credit Fees shall be shared by the Lenders (other than First Union) in
accordance  with  their Ratable Share and the other half of the Letter of Credit
Fees  shall  be paid to First Union. MSI or MSUK shall also pay to the Agent for
First  Union's  sole  account  First  Union's  then in effect customary fees and
administrative  expenses  payable  with respect to the Letter of Credit as First
Union  may  generally  charge  or incur from time to time in connection with the
issuance,  maintenance,  modification (if any), assignment or transfer (if any),
negotiation,  and administration of Letters of Credit. The Letter of Credit Fees
and any other fees and expenses described in this subsection shall be payable in
the  currency  in  which  the  applicable  Letter  of  Credit  is  issued.

     2.15.  DISBURSEMENTS,  REIMBURSEMENT.

          (a)  Immediately  upon  the  issuance  of  each Letter of Credit, each
Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to,
purchase  from  First  Union  a  participation in such Letter of Credit and each
drawing  thereunder  in  an  amount  equal to such Lender's Ratable Share of the
maximum  amount available to be drawn under such Letter of Credit and the amount
of  such  drawing,  respectively.

          (b) In the event of any request for a drawing under a Letter of Credit
by  the beneficiary or transferee thereof, the Agent will promptly notify MSI or
MSUK.  Upon  receiving  such notice, MSI or MSUK, as applicable, shall reimburse
(such  obligation  to  reimburse  the  Agent shall sometimes be referred to as a
"Reimbursement  Obligation") the Agent prior to 12:00 noon, New York time in the
case  of  any  payment  denominated in Dollars and 12:00 noon London time in the
case  of  any payment denominated in Pounds Sterling on each date that an amount
is  paid  by  the  Agent  under any Letter of Credit (each such date, a "Drawing
Date")  in  an  amount  equal to the amount so paid by the Agent and in the same
currency  in  which  the  Letter  of Credit was issued. In the event MSI or MSUK
fails to reimburse the Agent for the full amount of any drawing under any Letter
of  Credit,  by 12:00 noon (New York time or London time, as applicable), on the
Drawing  Date,  the  Agent  will promptly notify each Lender thereof, and MSI or

                                       29
<PAGE>
MSUK  shall be deemed to have requested that Revolving Advances of Domestic Rate
Loans  (as  to  MSI)  or  LIBOR  Rate  Loans  (as to MSUK) for such period(s) as
selected by the Agent be made by the Lenders to be disbursed on the Drawing Date
under  such Letter of Credit, subject to the amount of the unutilized portion of
the  Revolving  Credit  Commitment  and  subject  to the conditions set forth in
Section  8.2  other  than any notice requirements. Any notice given by the Agent
pursuant  to  this  Section  2.15(b)  may  be  oral  if immediately confirmed in
writing;  provided  that  the  lack  of such an immediate confirmation shall not
affect  the  conclusiveness  or  binding  effect  of  such  notice.

          (c) Each Lender shall upon any notice pursuant to Section 2.15(b) make
available  to  the  Agent  an amount in immediately available funds equal to its
Domestic  Rate  Loan  or  LIBOR  Rate Loan for such period(s) as selected by the
Agent,  as applicable, its Ratable Share of the amount of the drawing, whereupon
the  participating Lenders shall (subject to Section 2.15 (d)) each be deemed to
have  made  a  Revolving  Advance of a Domestic Rate Loan to MSI or a LIBOR Rate
Loan  to  MSUK,  as applicable, in that amount and in the same currency in which
the  Letter  of  Credit  was  issued.  If  any  Lender so notified fails to make
available  to  the  Agent  for  the  account  of  First Union the amount of such
Lender's  Ratable Share of such amount by no later than 2:00 p.m. on the Drawing
Date,  then  interest  shall  accrue  on  such  Lender's obligation to make such
payment  from  the  Drawing  Date  to  the  date on which such Lender makes such
payment  (1)  with respect to Revolving Advances to MSI: (i) at a rate per annum
equal  to  the  Federal Funds Rate during the first three (3) days following the
Drawing  Date;  and  (ii)  at  a  rate per annum equal to the rate applicable to
Advances  of  a  Domestic  Rate  Loan, on and after the fourth day following the
Drawing  Date;  and  (2)  with  respect  to  Revolving  Advances to MSUK, at the
applicable  Revolving Interest Rate, in each case for such period(s) as selected
by  the  Agent.  The  Agent  will  promptly give notice of the occurrence of the
Drawing  Date,  but  failure of the Agent to give any such notice on the Drawing
Date  or  in sufficient time to enable any Lender to effect such payment on such
date  shall  not  relieve  such  Lender  from  its obligation under this Section
2.15(c).

          (d)  With  respect  to  any unreimbursed drawing that is not converted
into  Revolving  Advances  of  Domestic Rate Loans to MSI or a continuation of a
LIBOR  Rate  Loan to MSUK, as applicable, in whole or in part as contemplated by
Section  2.15(b),  because  of MSI's or MSUK's failure to satisfy the conditions
set  forth in this Agreement other than any notice requirements or for any other
reason,  MSI  or  MSUK, as applicable, shall be deemed to have incurred from the
Agent a Letter of Credit Borrowing in the amount of such drawing and in the same
currency  in  which  the  Letter  of  Credit  was  issued. Such Letter of Credit
Borrowing  shall be due and payable on demand (together with interest) and shall
bear  interest  at  the  rate  per annum applicable to the Revolving Advances of
Domestic  Rate  Loans  or LIBOR Rate Loans, as applicable, in each case for such
period(s)  as selected by the Agent. Each Lender's payment to the Agent pursuant
to  Section  2.15(c)  shall  be  deemed  to  be  a  payment  in  respect  of its
participation  in  such  Letter  of  Credit  Borrowing  and  shall  constitute a
Participation  Advance  in  the  same currency in which the Letter of Credit was
issued  from  such  Lender in satisfaction of its participation obligation under
this  Section  2.15.

     2.16.  REPAYMENT  OF  PARTICIPATION  ADVANCES.

          (a)  Upon  (and  only  upon)  receipt  by the Agent for its account of
immediately available funds from MSI or MSUK, as applicable (i) in reimbursement
of  any  payment  made  by  the Agent under any Letter of Credit with respect to
which  any  Lender  has  made  a  Participation Advance to the Agent, or (ii) in

                                       30
<PAGE>
payment  of  interest on such a payment made by the Agent under such a Letter of
Credit,  the  Agent will pay to each Lender, in the same funds as those received
by  the  Agent,  the amount of such Lender's Ratable Share of such funds, except
the  Agent  shall  retain  the  amount of the Ratable Share of such funds of any
Lender  that  did not make a Participation Advance in respect of such payment by
Agent.

          (b)  If the Agent is required at any time to return to MSI, MSUK or to
a  trustee,  receiver,  liquidator, custodian, or any official in any Insolvency
Proceeding,  any  portion  of  the payments made by any MSI or MSUK to the Agent
pursuant  to Section 2.16(a) in reimbursement of a payment made under the Letter
of Credit or interest or fee thereon, each Lender shall, on demand of the Agent,
forthwith  return to the Agent the amount of its Ratable Share of any amounts so
returned by the Agent plus interest thereon from the date such demand is made to
the  date  such  amounts are returned by such Lender to the Agent, at a rate per
annum  equal  to  the  Federal  Funds  Rate  (for  amounts  in  Dollars) and the
applicable  Revolving  Interest  Rate (for amounts in Pounds Sterling) in effect
from  time  to  time,  in each case for such period(s) as selected by the Agent.

     2.17.  DOCUMENTATION.

          MSI  and  MSUK  agree  to  be  bound  by  the  terms  of First Union's
application  and  agreement  for  letters of credit executed by MSI and MSUK and
First  Union's  written  regulations and general customary practices relating to
letters  of  credit.  In  the  event  of  a conflict between such application or
agreement  and this Agreement, this Agreement shall govern. It is understood and
agreed that, except in the case of gross negligence or willful misconduct, First
Union  shall not be liable for any error, negligence and/or mistakes, whether of
omission  or  commission, in following any MSI's or MSUK's instructions or those
contained  in  the  Letters  of  Credit  or  any  modifications,  amendments  or
supplements  thereto.

     2.18.  DETERMINATIONS  TO  HONOR  DRAWING  REQUESTS.

          In  determining  whether  to  honor  any request for drawing under any
Letter  of  Credit  by the beneficiary thereof, First Union shall be responsible

under  such  Letter  of Credit have been delivered and that they comply on their
face  with  the  requirements  of  such  Letter  of  Credit.

     2.19.  NATURE  OF  PARTICIPATION  AND  REIMBURSEMENT  OBLIGATIONS.

          Each Lender's obligation in accordance with this Agreement to make the
Revolving  Credit Advances or Participation Advances, as contemplated by Section
2.15,  as a result of a drawing under a Letter of Credit, and the Obligations of
MSI  and MSUK to reimburse the Agent upon a draw under a Letter of Credit, shall
be  absolute,  unconditional and irrevocable, and shall be performed strictly in
accordance  with  the  terms  of  this  Section  2.19  under  all circumstances,
including  the  following  circumstances:

               (i) any set-off, counterclaim, recoupment, defense or other right
which  such Lender may have against the Agent, MSI, MSUK or any other Person for

               (ii)  the  failure of MSI, MSUK or any other Person to comply, in
connection  with  a Letter of Credit Borrowing, with the conditions set forth in

                                       31
<PAGE>
Sections  2.1,  2.2, 2.3, 2.4 or 8.2 or as otherwise set forth in this Agreement
for  the  making  of a Revolving Credit Advance, it being acknowledged that such
conditions  are  not required for the making of a Letter of Credit Borrowing and
the obligation of the Lenders to make Participation Advances under Section 2.15;

               (iii)  any  lack  of  validity or enforceability of any Letter of
Credit;

               (iv)  the existence of any claim, set-off, defense or other right
which  MSI, MSUK or any Lender may have at any time against a beneficiary or any
transferee  of any Letter of Credit (or any Persons for whom any such transferee
may  be  acting),  the  Agent  or  any Lender or any other Person or, whether in
connection  with  this  Agreement,  the  transactions contemplated herein or any
unrelated  transaction  (including  any underlying transaction between Lender or
Subsidiaries  of  MSI  and  the  beneficiary  for which any Letter of Credit was
procured);

               (v)  any  draft,  demand, certificate or other document presented
under  any  Letter  of Credit proving to be forged, fraudulent or invalid in any
respect  or any statement therein being untrue or inaccurate in any respect even
if  First  Union  has  been  notified  thereof;

               (vi)  any adverse change in the business, operations, properties,
assets,  condition  (financial or otherwise) or prospects of MSI, MSUK, Sensors,
Subsidiaries  of  MSI  or  any  other  Obligor;

               (vii)  any  breach of this Agreement or any Other Document by any
party  thereto;

               (viii)  the occurrence or continuance of an Insolvency Proceeding
with  respect  to  MSI,  MSUK  or  any  other  Obligor;

               (ix) the fact that an Event of Default shall have occurred and be
continuing;

               (x) the fact that the Term shall have passed or this Agreement or
the  Commitments  hereunder  shall  have  been  terminated;  and

               (xi)  any  other circumstance or happening whatsoever, whether or
not  similar  to  any  of  the  foregoing.

     2.20.  INDEMNITY.

          In  addition  to  amounts payable as provided in Section 13.5, MSI and
MSUK  hereby agree to protect, indemnify, pay and save harmless First Union from
and  against  any  and all claims, demands, liabilities, damages, losses, costs,
charges  and  expenses (including reasonable fees, expenses and disbursements of
counsel  and allocated costs of internal counsel) which First Union may incur or
be  subject  to as a consequence, direct or indirect, of (i) the issuance of any
Letter  of  Credit  for their respective accounts, other than as a result of (A)
the  gross  negligence  or  willful misconduct of First Union as determined by a
final  judgment  of  a  court  of  competent  jurisdiction or (B) subject to the
following  clause  (ii), the wrongful dishonor by First Union of a proper demand
for  payment  made  under any Letter of Credit for their respective accounts, or
(ii)  the  failure  of  First  Union to honor a drawing under any such Letter of
Credit  as a result of any act or omission, whether rightful or wrongful, of any
present  or future de jure or de facto government or governmental authority (all
such  acts  or  omissions  herein  called  "Governmental  Acts").

                                       32
<PAGE>
     2.21.  LIABILITY  FOR  ACTS  AND  OMISSIONS.

          As  between  MSI and MSUK on the one hand and First Union on the other
hand,  MSI  and MSUK assume all risks of the acts and omissions of, or misuse of
the  Letters  of  Credit  by,  the  respective  beneficiaries of such Letters of
Credit. In furtherance and not in limitation of the foregoing, First Union shall
not  be responsible for: (i) the validity, accuracy, genuineness or legal effect
of any document submitted by any party in connection with the application for an
issuance  of any such Letter of Credit, even if it should in fact prove to be in
any  or  all  respects  invalid,  insufficient, inaccurate, fraudulent or forged
(even  if  the  Agent  shall  have  been notified thereof); (ii) the validity or
sufficiency  of  any  instrument  transferring  or  assigning  or  purporting to
transfer  or  assign  any  such  Letter  of  Credit  or  the  rights or benefits
thereunder  or  proceeds  thereof,  in  whole  or in part, which may prove to be
invalid  or  ineffective for any reason; (iii) the failure of the beneficiary of
any  Letter  of  Credit, or any other party to which any Letter of Credit may be
transferred,  to comply fully with any conditions required in order to draw upon
such Letter of Credit, or any other claim of MSI or MSUK against any beneficiary
of any Letter of Credit, or any such transferee, or any dispute between or among
MSI  or MSUK and any beneficiary of any Letter of Credit or any such transferee;
(iv)  errors,  omissions, interruptions or delays in transmission or delivery of
any messages, by mail, cable, telegraph, telex or otherwise, whether or not they
be  in cipher; (v) errors in interpretation of technical terms; (vi) any loss or
delay in the transmission or otherwise of any document required in order to make
a  drawing under any such Letter of Credit or of the proceeds thereof; (vii) the
misapplication  by  the beneficiary of any such Letter of Credit of the proceeds
of  any  drawing under such Letter of Credit; or (viii) any consequences arising
from  causes beyond the control of First Union, including any Governmental Acts,
and  none of the above shall affect or impair, or prevent the vesting of, any of
First  Union's  rights  or  powers  hereunder. Nothing in the preceding sentence
shall  relieve  the  Agent  from liability for First Union's gross negligence or
willful  misconduct  in  connection  with actions or omissions described in such
clauses(i) through (viii) of such sentence. In furtherance and extension and not
in  limitation  of  the specific provisions set forth above, any action taken or
omitted  by First Union under or in connection with the Letters of Credit issued
by  it  or  any  documents  and  certificates  delivered thereunder, if taken or
omitted  in  good faith, shall not put First Union under any resulting liability
to  MSI,  MSUK  or  any  Lender.

     2.22.  PRO  RATA  TREATMENT  OF  LENDERS.

          Each  borrowing  shall  be  allocated  to each Lender according to its
Ratable  Share,  and each selection of, conversion to or renewal of any interest
rate  and  each  payment or prepayment by MSI or MSUK with respect to principal,
interest,  commitment  fees, facility fees, or other fees (except for the Letter
of  Credit  Fees and other fees payable only to First Union) or amounts due from
MSI or MSUK hereunder to the Lenders with respect to the Advances, shall (except
in  the  case  of  an  event  specified  in Section 2.16, 3.6 or 3.7) be made in
proportion  to  the  applicable Advances outstanding from each Lender and, if no
such  Advances  are then outstanding, in proportion to the Ratable Share of each
Lender.

     2.23.  REPLACEMENT  OF  A  LENDER.

          In  the event any Lender (i) gives notice under Section 3.5 or Section
3.6,  (ii)  does not fund Revolving Advances because the making of such Advances
would  contravene any Law applicable to such Lender, or (iii) becomes subject to
the  control  of an Official Body (other than normal and customary supervision),
then  MSI and MSUK shall have the right at their option, with the consent of the
Agent,  which shall not be unreasonably withheld, to prepay the Advances of such
Lender  in whole, together with all interest accrued thereon, and terminate such
Lender's  Commitment  within ninety (90) days after (w) receipt of such Lender's

                                       33
<PAGE>
notice  under  Section  3.5  or 3.6, (x) the date such Lender has failed to fund
Revolving  Advances  because  the  making  of such Advances would contravene Law
applicable  to  such  Lender  or  (y) the date such Lender became subject to the
control  of  an  Official  Body, as applicable; provided that MSI and MSUK shall
also  pay  to  such  Lender  at the time of such prepayment any amounts required
under  Sections  2.2(g)  and 3.5 and any accrued interest due on such amount and
any  related  fees;  provided, however, that the Commitment and any Term Loan of
such  Lender shall be provided by one or more of the remaining Lenders (at their
option)  or  a  replacement bank acceptable to the Agent; provided, further, the
remaining  Lenders  shall  have  no  obligation  hereunder  to  increase  their
Commitments.  Notwithstanding  the  foregoing,  the  Agent  may only be replaced
subject  to  the  requirements of Section 13.14 and provided that all Letters of
Credit  have  expired  or  been  terminated  or  replaced.

     2.24.  LETTERS  OF  CREDIT  OUTSTANDING.

          Upon  an  Event  of  Default, the full amount of all Letters of Credit
Outstanding  shall be deemed to increase the principal amount outstanding of the
Revolving  Advances  (and  any  unpaid  interest thereon and on unpaid letter of
credit  fees shall be deemed principal on such Revolving Advances, provided that
                                                                   -------- ----
no  interest  shall be charged on the amount of the Letters of Credit unless and
until such Letters of Credit are drawn upon) for purposes of (x) distribution of
payments  hereunder  and  (y) application of proceeds; provided, however, if any
such  Letter  of  Credit thereafter expires without being drawn upon, the amount
thereof  shall  reduce  the  principal  amount  of  the  Revolving  Advances (as
previously  increased  pursuant  to  this section 2.24) and the distributions of
payments  and  proceeds  to the Agent and Lenders shall be adjusted accordingly.

     2.25.  CURRENCY  CONVERSION.

          In  calculating  the  maximum  Dollar  amounts  referenced in Sections
2.1(a)(ii),  2.1(a)(iv),  2.6,  2.8, 2.11(c) and 2.14(a) hereof, the Agent shall
convert  Pounds Sterling or Canadian dollars, as applicable, into Dollars at the
closing  spot  exchange  rate  of  the  Agent  then  prevailing (as conclusively
determined  by  the  Agent) for purchasing Dollars with such other currency. All
moneys  received  or held by the Agent or any of the Lenders hereunder may, from
time  to time, after demand has been made, be converted into such other currency
as  the  Agent  or  such  Lender  considers  necessary or desirable to cover the
Obligations of the applicable Obligor in that other currency at the closing spot
exchange  rate  of the Agent or such Lender, as the case may be, then prevailing
(as  conclusively  determined  by  the Agent or such Lender) for purchasing that
other  currency  with  the  existing  currency.  If  and  to the extent that the
applicable  Obligor fails to pay any amount due on demand, the Agent may, in its
absolute  discretion  and  without  notice  to the Obligor, purchase at any time
thereafter so much of any currency as the Agent considers necessary or desirable
to  cover  the  Obligations  of  the  applicable Obligor in such currency hereby
secured  at  the  closing  spot  exchange  rate of the Agent then prevailing (as
conclusively determined by the Agent) for purchasing such currency with Dollars,
and  the  Obligor  shall indemnify the Agent and the Lenders and each of them in
respect  of  the  amount of Dollars used by the Agent for such purchase together
with  any  related  costs  or  expenses  necessary to effect such conversion. No

                                       34
<PAGE>
payment  to the Agent or any of the Lenders (whether under any judgment or court
order or otherwise) shall discharge the Obligations of any Obligor in respect of
which it was made unless and until the Agent and the Lenders shall have received
payment  in  full in the currency in which such Obligations were incurred and to
the  extent  that the amount of any such payment shall on actual conversion into
such  currency  fall  short  of such Obligations expressed in that currency, the
Agent  and the Lenders shall have a further separate cause of action against the
applicable  Obligor and shall be entitled to enforce the Liens hereby created to
recover  the  amount  of  the  shortfall.

3.   INTEREST  AND  FEES.
     -------------------

     3.1. INTEREST.

          Interest  on Advances shall be payable by MSI or MSUK, as the case may
be,  in  arrears  on  the  first day of each month with respect to Domestic Rate
Loans and, with respect to LIBOR Rate Loans, at the end of each Interest Period.
Interest  charges  shall  be computed on the actual principal amount of Advances
outstanding  during the month (the "Monthly Advances") at a rate per annum equal
to  (i)  with  respect  to Revolving Advances, the applicable Revolving Interest
Rate  and  (ii) with respect to the Term Loan, the Term Loan Rate (collectively,
as  applicable,  the  "Contract  Rate").  All  Revolving Advances under the MSUK
Sublimit  shall  be  LIBOR  Rate Loans. Whenever, subsequent to the date of this
Agreement,  the  Prime  Rate  is increased or decreased, the applicable Contract
Rate for Domestic Rate Loans shall be similarly changed without notice or demand
of  any  kind  by an amount equal to the amount of such change in the Prime Rate
during  the  time  such  change  or  changes  remain  in  effect. The LIBOR Rate
(Dollars)  and  LIBOR  Rate  (Pounds Sterling) shall be adjusted with respect to
LIBOR  Rate  Loans without notice or demand of any kind on the effective date of
any  change  in the Reserve Percentage as of such effective date. Upon and after
the  occurrence of an Event of Default, and during the continuation thereof, the
Obligations shall bear interest at the applicable Contract Rate plus two percent
(2%)  per  annum  (the  "Default  Rate").

     3.2. COMMITMENT  FEE.

          If, for any month during the Term, the average daily unused balance of
the  Revolving  Advances  for  each day of such month does not equal the Maximum
Revolving  Advance  Amount, then MSI shall pay to Agent, for the ratable benefit
of  Lenders,  a fee at a rate equal to (i) three-eighths of one percent (0.375%)
per  annum  if  the  ratio of Consolidated Funded Indebtedness to EBITDA is less
than  2.25  to  1.00  and,  (ii) one half of one percent (0.5%) per annum if the
ratio  of Consolidated Funded Indebtedness to EBITDA is equal to or greater than
2.25  to  1.00,  in  either  case  on  the amount by which the Maximum Revolving
Advance  Amount  exceeds  such  average  daily unused balance. Such fee shall be
payable  to  Agent  in  arrears  on  the  last day of each calendar quarter. The
calculation  of  the  above  ratio  (and  any  adjustment  in fee) shall be made
quarterly  based  upon MSI's consolidated financial statements provided to Agent
and  shall  become  effective  five (5) days after Agent receives such financial
statements  as  same  are  provided  as  required  by  Section  9.8  hereof.

     3.3. COMPUTATION  OF  INTEREST  AND  FEES.

          Interest  and  fees hereunder shall be computed on the basis of a year
of  360 days (with respect to Advances in Dollars) and 365 days (with respect to
Advances  in  Pounds Sterling) and for the actual number of days elapsed. If any

                                       35
<PAGE>
payment  to  be  made  hereunder  becomes  due and payable on a day other than a
Business  Day,  the  due  date  thereof shall be extended to the next succeeding
Business  Day  and interest thereon shall accrue at the applicable Contract Rate
during  such  extension  and  be  payable  with  such  payment.

     3.4. MAXIMUM  CHARGES.

          In  no  event  whatsoever  shall  interest  and  other charges charged
hereunder  exceed  the highest rate permissible under law. In the event interest
and  other charges as computed hereunder would otherwise exceed the highest rate
permitted  under  law,  such  excess amount shall be first applied to any unpaid
principal  balance owed by MSI and MSUK, and if the then remaining excess amount
is  greater  than the previously unpaid principal balance, Lender shall promptly
refund  such  excess  amount  to MSI and MSUK and the provisions hereof shall be
deemed  amended  to  provide  for  such  permissible  rate.

     3.5. INCREASED  COSTS.

          (a)  In  the  event  that subsequent to the date hereof any applicable
law,  treaty  or  governmental  regulation,  or  any  change  therein  or in the
interpretation  or  application  thereof,  or  compliance  by any Lender and the
office  or  branch  where  Agent or any Lender makes or maintains any LIBOR Rate
Loans  with  any  request  or directive (whether or not having the force of law)
from  any  central  bank or other financial, monetary or other authority, shall:

               (1)  subject  Agent  or  such  Lender  to  any  tax  of  any kind
whatsoever  with  respect  to this Agreement or any Other Document or change the
basis  of  taxation  of  payments  to  Agent  or such Lender of principal, fees,
interest  or  any  other  amount  payable hereunder or under any Other Documents
(except  for  changes  in  the rate of tax on the overall net income of Agent or
such  Lender  by  the  jurisdiction in which it maintains its principal office);

               (2)  impose,  modify  or  hold  applicable  any  reserve, special
deposit,  assessment  or similar requirement against assets held by, or deposits
in or for the account of, advances or loans by, or other credit extended by, any
office  of  Agent  or  such  Lender,  including (without limitation) pursuant to
Regulation  D  of  the  Board  of  Governors  of  the Federal Reserve System; or

               (3) impose on Agent or such Lender or the London interbank market
any  other  condition  with  respect  to  this  Agreement or any Other Document;

and  the result of any of the foregoing is to increase the cost to Agent or such
Lender  of  making,  renewing or maintaining its Advances hereunder by an amount
that  Agent  or  such Lender deems to be material or to reduce the amount of any
payment  (whether  of principal, interest or otherwise) in respect of any of the
Advances  by  an amount that Agent or such Lender deems to be material, then, in
any such case, MSI or MSUK, as the case may be, shall promptly pay Agent or such
Lender,  within  ten  (10)  days following its demand, such additional amount as
will compensate Agent or such Lender for such additional cost or such reduction,
as  the case may be.  Lender shall certify the amount of such additional cost or
reduced amount to MSI or MSUK, and such certification shall be conclusive absent
manifest  error.

     (b) In the event that any Revolving Advances (or any part thereof) are made
to  MSUK  or  MSI  from a London branch of the Lenders, then MSUK or MSI, as the
case  may  be,  shall  promptly  pay  Agent,  within ten (10) days following its
demand,  the  amounts  calculated  in accordance with Section 15.23 hereof if so

                                       36
<PAGE>
required by the Agent. Agent shall certify the amount of such additional cost to
MSUK  or  MSI,  as  the  case may be, and such certification shall be conclusive
absent  manifest  error.

     3.6. BASIS  FOR  DETERMINING  INTEREST  RATE  INADEQUATE  OR  UNFAIR.

          (a)  In  the event that Agent or any Lender shall have determined that
(i)  reasonable  means  do  not  exist for ascertaining the LIBOR Rate (Dollars)
applicable  pursuant  to  Section  2.2  hereof  for any Interest Period; or (ii)
Dollar  deposits  in  the  relevant amount and for the relevant maturity are not
available  in  the London interbank market, with respect to an outstanding LIBOR
Rate  Loan,  a  proposed LIBOR Rate Loan, or a proposed conversion of a Domestic
Rate  Loan  into  a LIBOR Rate Loan, then each affected Lender shall give Agent,
and  Agent  shall  give MSI, prompt written, telephonic or telegraphic notice of
such  determination.  If such notice is given, (i) any such requested LIBOR Rate
Loan  shall  be  made  as a Domestic Rate Loan, unless MSI shall notify Agent no
later than 10:00 a.m. (New York time) two (2) Business Days prior to the date of
such  proposed  borrowing, that its request for such borrowing shall be canceled
or made as an unaffected type of LIBOR Rate Loan, (ii) any Domestic Rate Loan or
LIBOR  Rate  Loan  which was to have been converted to an affected type of LIBOR
Rate  Loan  shall be continued as or converted into a Domestic Rate Loan, or, if
MSI  shall  notify  Agent,  no  later  than  10:00  a.m. (New York time) two (2)
Business  Days  prior  to  the  proposed  conversion,  shall be maintained as an
unaffected  type  of  LIBOR  Rate Loan, and (iii) any outstanding affected LIBOR
Rate Loans shall be converted into a Domestic Rate Loan, or, if MSI shall notify
Agent,  no  later than 10:00 a.m. (New York time) two (2) Business Days prior to
the  last  Business  Day  of the then current Interest Period applicable to such
affected  LIBOR  Rate  Loan, shall be converted into an unaffected type of LIBOR
Rate Loan, on the last Business Day of the then current Interest Period for such
affected  LIBOR  Rate Loans. Until such notice has been withdrawn, Lenders shall
have  no  obligation  to  make  an  affected type of LIBOR Rate Loan or maintain
outstanding  affected  LIBOR  Rate  Loans  and  MSI  shall not have the right to
convert  a  Domestic  Rate Loan or an unaffected type of LIBOR Rate Loan into an
affected  type  of  LIBOR  Rate  Loan.

          (b)  In  the event that Agent or any Lender shall have determined that
for  any  Interest Period (i) reasonable means do not exist for ascertaining the
LIBOR  Rate (Pounds Sterling) applicable pursuant to Section 2.2 hereof, or (ii)
Pounds  Sterling  is  unavailable to a Lender at a rate equivalent to the screen
rate  quoted  by  the  British  Bankers'  Association  as set forth on Dow Jones
Markets  Service  (formerly known as Telerate) display page 3750 (or appropriate
successor  or  if  the  British  Bankers' Association or its successor ceases to
provide  such  quotes,  a  comparable replacement determined by the Agent), then
each affected Lender shall give Agent, and Agent shall give MSI, prompt written,
telephonic or telegraphic notice of such determination. If such notice is given,
then  no  Revolving  Advances  shall  be  made  to  MSUK  during  such  period.

     3.7. CAPITAL  ADEQUACY.

          (a)  In  the  event  that  subsequent  to the date hereof Agent or any
Lender  shall  have  determined  that  any  applicable  law, rule, regulation or
guideline  regarding  capital  adequacy, or any change therein, 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  Agent  or Lender and the office or
branch  where  such Agent or Lender makes or maintains any LIBOR Rate Loans with

                                       37
<PAGE>
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 Agent's or such Lender's
capital  as  a  consequence  of  its obligations hereunder to a level below that
which  Agent or such Lender could have achieved but for such adoption, change or
compliance  (taking  into  consideration  Agent's or such Lender's policies with
respect  to  capital adequacy) by an amount deemed by Agent or such Lender to be
material,  then,  from  time to time, MSI or MSUK, as the case may be, shall pay
within  ten  (10)  days following demand to Agent or such Lender such additional
amount or amounts as will compensate Agent or such Lender for such reduction. In
determining  such  amount or amounts, Lender may use any reasonable averaging or
attribution  methods.  The  protection of this Section 3.7 shall be available to
Agent  and  Lenders  regardless  of  any  possible  contention  of invalidity or
inapplicability  with  respect  to  the applicable law, regulation or condition.

          (b)  A certificate of such Lender setting forth such amount or amounts
as shall be necessary to compensate Agent or such Lender with respect to Section
3.7(a) hereof when delivered to MSI and MSUK shall be conclusive absent manifest
error.

     3.8. CURRENCY  CHANGE  IN  THE  UNITED  KINGDOM.

          (a)  If  a  change  in  the  currency  of the United Kingdom occurs (a
"Currency Change"), this Agreement shall be amended to the extent that the Agent
specifies  to be necessary to reflect the Currency Change and to put the Lenders
in  the  same  position,  so  far  as possible, as they would have been in if no
Currency  Change  had  occurred.

          (b)  Without  prejudice to paragraph (a) above, any references in this
Agreement to a Business Day, day-count fraction or other convention (whether for
the  calculation of interest, determination of payment dates or otherwise) shall
be  amended,  with  effect  from  or at any time after a Currency Change, to the
extent  that  the  Agent specifies to be necessary, to comply with, or otherwise
reflect  or  accommodate, any generally accepted conventions and market practice
applicable  to  obligations  in  the  relevant  currency in the London Interbank
Market.

          (c)  The  Agent  shall  promptly  notify  the  other  parties  to this
Agreement  of  any amendment effected under subsections (a) and (b) and any such
amendment  shall  be  binding  on  all  parties  to  this  Agreement.

4.   COLLATERAL:  GENERAL  TERMS
     ---------------------------

     4.1. SECURITY  INTEREST  IN  THE  COLLATERAL  AND  SUBSIDIARY  COLLATERAL.

          (a)  Pursuant to the Existing Loan Agreement, MSI granted to the Agent

continued.  To secure the prompt payment and performance to Agent and Lenders of
the  Obligations (as such term is modified hereby), MSI hereby assigns, pledges,
charges  and  grants  to  Agent  for the ratable benefit of Lenders a continuing
security interest in and to all of the Collateral, whether now owned or existing

Agent's  security  interest  and shall cause its financial statements to reflect
such  security  interest.

          (b)  Pursuant  to  the First Mortgage Debenture, MSUK has assigned and
charged  to  Agent  for  the  ratable  benefit  of Lenders a continuing security
interest  in  and to all of the Subsidiary Collateral of MSUK, whether now owned
or  existing  or  hereafter  acquired  or  arising  and  wherever located, which
security  interest secures the obligations of MSUK hereunder and under the Notes
executed  by  MSUK and the Other Documents executed by MSUK. MSUK shall mark its
books  and  records  as may be necessary or appropriate to evidence, protect and
perfect  Agent's  security  interest and shall cause its financial statements to
reflect  such  security  interest.

          (c)  Pursuant  to  the  Security  Agreement of Sensors dated August 7,
2000,  Sensors  agreed  to  assign,  pledge  and  grant to Agent for the ratable
benefit  of  Lenders  a  continuing  security  interest  in  and  to  all of the

ratified,  confirmed and continued by Sensors in the Sensors Security Agreement.

financial  statements  to  reflect  such  security  interest.

     4.2. PERFECTION  OF  SECURITY  INTEREST.

          MSI,  MSUK  and Sensors shall take all action that may be necessary or
desirable,  or  that  Agent  may  request,  so  as  at all times to maintain the
validity,  perfection,  enforceability and priority of Agent's security interest
in  the  Collateral  and in Subsidiary Collateral or to enable Agent to protect,

maintenance  or  continuation  of  Agent's  security  interest under the Uniform
Commercial  Code  or  other applicable law. All charges, expenses and fees Agent
and/or  Lenders  may  incur  in  doing any of the foregoing, and any local taxes
relating thereto, shall be charged to Borrowers' Accounts as a Revolving Advance
of  a  Domestic  Rate  Loan and added to the Obligations, or, at Agent's or such
Lender's  option, shall be paid to Agent or such Lender immediately upon demand.

     4.3. DISPOSITION  OF  COLLATERAL.

     4.4. PRESERVATION  OF  COLLATERAL  AND  SUBSIDIARY  COLLATERAL.

          In  addition  to  the  rights  and  remedies set forth in Section 11.1
hereof,  Agent:  (a) may at any time take such steps as Agent deems necessary to
protect Agent's and each Lender's interest in and to preserve the Collateral and
the  Subsidiary  Collateral, including the hiring of such security guards or the
placing of other security protection measures as Agent may deem appropriate; (b)
may  employ and maintain at any of MSI's, MSUK's or any other Obligor's premises

Collateral;  (c)  may  lease warehouse facilities to which Agent may move all or
part  of the Collateral and the Subsidiary Collateral; (d) may use any of MSI's,

ingress  and  egress  to  the  places  where  the  Collateral and the Subsidiary
Collateral  is located, and may proceed over and through any of MSI's, MSUK's or
any  other  Obligor's owned or leased property. MSI, MSUK and the other Obligors
shall cooperate fully with all of Agent's efforts to preserve the Collateral and
the  Subsidiary Collateral and will take such actions to preserve the Collateral
and  the  Subsidiary  Collateral  as Agent may direct. All of Agent's and or any
Lender's  expenses  of  preserving the Collateral and the Subsidiary Collateral,
including  any expenses relating to the bonding of a custodian, shall be charged
to  Borrowers' Accounts as a Revolving Advance of a Domestic Rate Loan and added
to  the  Obligations.

     4.5. OWNERSHIP  OF  COLLATERAL  AND  SUBSIDIARY  COLLATERAL.

          With  respect to the Collateral and Subsidiary Collateral, at the time
the  Collateral  and  Subsidiary  Collateral becomes subject to Agent's security
interest:  (a)  MSI, MSUK and Sensors, as applicable, shall be the sole owner of
and  fully  authorized and able to sell, transfer, pledge, charge and/or grant a
first  priority  security  interest in each and every item of the Collateral and
Subsidiary  Collateral  to  Agent;  and,  except  for Permitted Encumbrances the
Collateral shall be free and clear of all Liens and encumbrances whatsoever; (b)
each document and agreement executed by MSI, MSUK and Sensors, as applicable, or
delivered  to Agent and/or any Lender in connection with this Agreement shall be

the  sale  of  Inventory in the ordinary course of business and Equipment to the
extent  permitted  in  Section  4.3  hereof.

     4.6. DEFENSE  OF  AGENT'S  AND  EACH  LENDER'S  INTERESTS.

          Until  (a)  unavoidable  payment and performance in full of all of the
Obligations  (including  cash collateralizing any Letters of Credit Outstanding)
and  (b)  termination  of  this  Agreement and all obligations of the Lenders to
extend  credit  hereunder, Agent's and each Lender's interests in the Collateral

                                       40
<PAGE>
shall  continue  in full force and effect. During such period MSI and MSUK shall
not,  without  Agent's  prior  written  consent,  pledge,  charge,  sell (except
Inventory  sold  in  the ordinary course of business and Equipment to the extent
permitted  in Section 4.3 hereof), assign, transfer, create or suffer to exist a
Lien  upon or encumber or allow or suffer to be encumbered in any way except for
Permitted Encumbrances, any part of the Collateral or the Subsidiary Collateral.
MSI,  MSUK  and  Sensors,  as applicable, shall defend Agent's and each Lender's
interests  in  the  Collateral and the Subsidiary Collateral against any and all
Persons  whatsoever. At any time following demand by Agent and/or any Lender for
payment of all Obligations, Agent shall have the right to take possession of the
indicia  of  the  Collateral  and the Subsidiary Collateral in whatever physical
form  contained,  including  without  limitation: labels, stationery, documents,
instruments  and  advertising  materials.  If Agent exercises such right to take
possession  of  the  Collateral  and/or  Subsidiary  Collateral,  MSI,  MSUK and
Sensors,  as  applicable,  shall,  upon  demand,  assemble it in the best manner
possible  and  make  it  available  to Agent at a place reasonably convenient to
Agent.  In  addition,  with  respect  to  all  Collateral  and  the  Subsidiary
Collateral,  Agent shall be entitled to all of the rights and remedies set forth
herein  and  further provided by the Uniform Commercial Code or other applicable
law.  MSI, MSUK and Sensors, as applicable, shall, and Agent may, at its option,
instruct  all suppliers, carriers, forwarders, warehouses or others receiving or
holding cash, checks, Inventory, documents or instruments in which Agent holds a
security  interest  to deliver same to Agent and/or subject to Agent's order and
if they shall come into MSI's, MSUK's and Sensor's possession, they, and each of
them, shall be held by MSI, MSUK and Sensors, as applicable, in trust as Agent's
trustee,  and MSI or MSUK will immediately deliver them to Agent Lender in their
original  form  together  with  any  necessary  endorsement.

     4.7. BOOKS  AND  RECORDS.

          MSI, MSUK and the other Obligors shall (a) keep proper books of record
and account in which full, true and correct entries will be made of all dealings
or transactions of or in relation to its business and affairs; (b) set up on its
books  accruals  with  respect  to  all  taxes, assessments, charges, levies and
claims;  and  (c)  on  a  reasonably current basis set up on its books, from its
earnings,  allowances against doubtful Receivables, advances and investments and
all  other  proper  accruals  (including  without  limitation  by  reason  of
enumeration,  accruals  for  premiums,  if  any,  due  on  required payments and
accruals  for  depreciation, obsolescence, or amortization of properties), which
should  be  set  aside  from  such earnings in connection with its business. All
determinations  pursuant to this subsection shall be made in accordance with, or
as  required  by,  GAAP  consistently applied in the opinion of such independent
public  accountant  as  shall  then  be  regularly  engaged  by MSI and/or MSUK.

     4.8. FINANCIAL  DISCLOSURE.

          MSI  and  MSUK hereby irrevocably authorize and direct all accountants
and auditors employed by MSI and MSUK at any time during the Term to exhibit and
deliver  to  Agent and Lenders copies of any of MSI's, MSUK's or other Obligor's
financial  statements, trial balances or other accounting records of any sort in
the  accountant's  or auditor's possession, and to disclose to Agent and Lenders
any  information such accountants may have concerning MSI's, MSUK's and/or other
Obligor's  financial  status  and  business  operations.  MSI  and  MSUK  hereby
authorize  all  federal, state and municipal authorities to furnish to Agent and

                                       41
<PAGE>
Lenders  copies  of reports or examinations relating to MSI, MSUK and/or another
Obligor, whether made by MSI, MSUK or otherwise; however, Agent and Lenders will
attempt  to obtain such information or materials directly from MSI or MSUK prior
to  obtaining  such  information  or  materials  from  such  accountants or such
authorities.

     4.9. COMPLIANCE  WITH  LAWS.

          MSI,  MSUK  and  the other Obligors shall comply with all acts, rules,
regulations  and  orders  of any legislative, administrative or judicial body or
official  applicable  to  the Collateral and/or the Subsidiary Collateral or any
part  thereof  or  to  the  operation  of  MSI's,  MSUK's or any other Obligor's
business  the  non-compliance  with which could reasonably be expected to have a
Material  Adverse  Effect.  The  Collateral and the Subsidiary Collateral at all
times  shall  be maintained in accordance with the requirements of all insurance
carriers  which  provide  insurance  with  respect  to the Collateral and/or the
Subsidiary  Collateral  so  that  such  insurance shall remain in full force and
effect.

     4.10.  INSPECTION  OF  PREMISES.

          At all reasonable times and upon reasonable advance notice Agent shall
have  full  access  to and the right to audit, check, inspect and make abstracts

correspondence  and  all  other  papers  relating  to  the Collateral and/or the
Subsidiary  Collateral  and  the  operation  of  MSI's,  MSUK's and/or the other
Obligors'  business.  Agent,  may  enter  upon  any  of MSI's, MSUK's and/or any
Obligor's premises at any time during business hours and at any other reasonable
time,  and  from  time to time, for the purpose of inspecting the Collateral and
any and all records pertaining thereto and the operation of MSI's, MSUK's and/or
any  other Obligor's business. So long as no Event of Default then exists and is
continuing,  Agent  may  conduct one field exam of MSI, MSUK, Sensors and of any
other  Guarantor  each  year, at the expense of MSI, MSUK, Sensors or such other
Guarantor.  Any  field  exams or other audits after an Event of Default which is
continuing  shall  be  at  the  expense  of  MSI  or  MSUK.

     4.11.  INSURANCE.

          MSI shall bear the full risk of any loss of any nature whatsoever with
respect  to  the  Collateral and MSUK and Sensors, as applicable, shall bear the
full  risk  of  any loss of any nature whatsoever with respect to the Subsidiary
Collateral.  At  MSI's,  MSUK's  and the other Obligor's own cost and expense in
amounts  and with carriers acceptable to Agent, MSI, MSUK and the other Obligors
shall: (a) keep all its insurable properties and properties in which any of them
has  an  interest insured against the hazards of fire, flood, sprinkler leakage,
those hazards covered by extended coverage insurance and such other hazards, and
for  such  amounts,  as is customary in the case of companies engaged in similar
businesses  including,  without limitation, business interruption insurance; (b)
maintain a bond in such amounts as is customary in the case of companies engaged
in  similar  businesses insuring against larceny, embezzlement or other criminal
misappropriation  of  insured's  officers and employees who may either singly or
jointly  with others at any time have access to the assets or funds of MSI, MSUK
and/or the other Obligors either directly or through authority to draw upon such
funds or to direct generally the disposition of such assets; (c) maintain public
and  product  liability  insurance  against claims for personal injury, death or
property  damage suffered by others; (d) maintain all such worker's compensation
or  similar  insurance  as  may  be  required  under  the  laws  of any state or
jurisdiction in which any of them is engaged in business; (e) furnish Agent with
(i)  copies  of all policies and evidence of the maintenance of such policies by
the  renewal  thereof  at least thirty (30) days before any expiration date, and
(ii) appropriate loss payable endorsements in form and substance satisfactory to

                                       42
<PAGE>
Agent,  naming  Agent as a co-insured and loss payee as its interests may appear
with  respect  to all insurance coverage referred to in clauses (a), and (c) and
(e)  above  with  respect to MSI, MSUK and the other Obligors, and providing (A)
that  all  proceeds  thereunder shall be payable to Agent, (B) no such insurance
shall  be affected by any act or neglect of the insured or owner of the property
described  in such policy, and (C) that such policy and loss payable clauses may
not  be  canceled, amended or terminated unless at least thirty (30) days' prior
written  notice  is  given  to  Agent.  In the event of any loss thereunder, the
carriers  named  therein  hereby  are directed by Agent, MSI, MSUK and the other
Obligors  to make payment for such loss to Agent and not to MSI, MSUK and/or the
other  Obligors  and  Agent  jointly. If any insurance losses are paid by check,
draft  or  other  instrument  payable to MSI, MSUK and/or the other Obligors and
Agent  jointly,  Agent may endorse MSI's, MSUK's and/or the other Obligors' name
thereon  and do such other things as Agent may deem advisable to reduce the same
to  cash.  Agent  is  hereby  authorized  to  adjust and compromise claims under
insurance  coverage  referred to in clauses (a), and (b) and (e) above. All loss
recoveries  received  by  Agent  upon  any  such insurance may be applied to the
Obligations,  in  such  order  as  Agent in its sole discretion shall determine,
except  as  may be required by law. Any surplus shall be paid by Agent to MSI or
MSUK  or  applied  as  may  be otherwise required by law. Any deficiency thereon
shall  be  paid  by  MSI  or  MSUK  to  Agent,  on  demand.

     4.12.  FAILURE  TO  PAY  INSURANCE.

          If  MSI  or MSUK fails to obtain insurance as hereinabove provided, or
to  keep the same in force, Agent, if Agent so elects, may obtain such insurance
and  pay  the  premium therefor on behalf of MSI, MSUK and/or any other Obligor,
and  charge  Borrowers'  Accounts  therefor as a Revolving Advance of a Domestic
Rate  Loan  and  such  expenses  so  paid  shall  be  part  of  the Obligations.

     4.13.  PAYMENT  OF  TAXES.

          MSI,  MSUK  and  the  other  Obligors  will  pay, when due, all taxes,
assessments  and  other  Charges  lawfully levied or assessed upon MSI, MSUK the
other  Obligors  or  any  of  the Collateral or Subsidiary Collateral including,
without  limitation,  real  and personal property taxes, assessments and charges
and  all  franchise,  income, employment, social security benefits, withholding,
and  sales  taxes. If any tax by any governmental authority is or may be imposed
on  or as a result of any transaction between MSI, MSUK and/or Sensors and Agent
and/or  any  Lender which Agent and/or any Lender may be required to withhold or
pay  or if any taxes, assessments, or other Charges remain unpaid after the date
fixed  for their payment, or if any claim shall be made which, in Agent's or any
Lender's  opinion, may possibly create a valid Lien on the Collateral and/or the
Subsidiary  Collateral,  Agent  may without notice to MSI or MSUK pay the taxes,
assessments  or  other  Charges and MSI and MSUK hereby indemnify and hold Agent
and  each Lender harmless in respect thereof. The amount of any payment by Agent
under  this  Section 4.13 shall be charged to Borrowers' Accounts as a Revolving
Advance  and  added  to the Obligations and, until MSI and/or MSUK shall furnish

                                       43
<PAGE>
Agent  with an indemnity therefor (or supply Agent with evidence satisfactory to
Agent  that due provision for the payment thereof has been made), Agent may hold
without  interest any balance standing to MSI's or MSUK's credit and Agent shall
retain  its  security  interest  in  any  and  all  Collateral  held  by  Agent.

     4.14.  PAYMENT  OF  LEASEHOLD  OBLIGATIONS.

          MSI,  MSUK  and the other Obligors shall at all times pay, when and as
due,  its  rental  obligations  under all leases under which it is a tenant, and
shall  otherwise  comply, in all material respects, with all other terms of such
leases  and  keep  them  in  full  force and effect and, at Agent's request will
provide  evidence  of  having  done  so.

     4.15.  RECEIVABLES.

          (a)  Nature  of  Receivables.
               -----------------------

               Each  of  the  Receivables shall be a bona fide and valid account
representing  a  bona  fide indebtedness incurred by the Customer therein named,
for  a  fixed  sum  as  set  forth  in  the  invoice  relating thereto (provided
immaterial  or  unintentional  invoice errors shall not be deemed to be a breach
hereof)  with  respect  to  an absolute sale or lease and delivery of goods upon
stated  terms of MSI or MSUK, or work, labor or services theretofore rendered by
MSI  or  MSUK  as  of the date each Receivable is created. Same shall be due and
owing in accordance with MSI's or MSUK's standard terms of sale without dispute,
setoff  or  counterclaim  except  as  may  be  stated on the accounts receivable
schedules  delivered  by  MSI  and  MSUK  to  Agent.

          (b)  Solvency  of  Customers.
               -----------------------

               Each  Customer,  to the best of MSI's and MSUK's knowledge, as of
the  date each Receivable is created, is and will be solvent and able to pay all
Receivables  on which the Customer is obligated in full when due or with respect
to such Customers of MSI and MSUK who are not solvent MSI and MSUK has set up on
its  books and in its financial records bad debt reserves adequate to cover such
Receivables.

          (c)  Locations  of  MSI  and  MSUK.
               ------------------------------

               MSI's  chief executive office is located at 80 Little Falls Road,
Fairfield,  New  Jersey  07004. Until written notice is given to Agent by MSI of
any  other  office at which MSI keeps its records pertaining to Receivables, all
such  records  shall  be  kept  at such executive office. MSUK's chief executive
office  is  located at 534/544 Ipswich Road, Slough, Berkshire SL1 4EG, England.
Until written notice is given to Agent by MSUK of any other office at which MSUK
keeps  its  records pertaining to Receivables, all such records shall be kept at
such  executive  office.

          (d)  Collection  of  Receivables.
               ---------------------------

               Until  MSI's  or MSUK's authority to do so is terminated by Agent
(which notice Agent may give at any time following the occurrence of an Event of
Default  or  a  Default  or  when Agent in its sole discretion deems it to be in
Agent's  and  each Lenders' best interest to do so), MSI and MSUK will, at MSI's
and MSUK's sole cost and expense, but on Agent's behalf and for Agent's account,
collect  as  Lender's  property and in trust for Lenders all amounts received on
Receivables, and shall not commingle such collections with MSI's or MSUK's funds
or  use  the same except to pay Obligations. MSI and MSUK shall, upon request by
Agent, deliver to Agent, or deposit in the Blocked Account, in original form and

                                       44
<PAGE>
on  the  date  of  receipt  thereof,  all  checks,  drafts, notes, money orders,
acceptances,  cash  and  other  evidences of indebtedness, the proceeds of which
shall  be  applied  to  repayment  of  the  Revolving  Advances.

          (e)  Notification  of  Assignment  of  Receivables.
               ---------------------------------------------

               At  any time following the occurrence of an Event of Default or a
Default,  Agent  shall  have  the right to send notice of the assignment of, and
Agent's  security  interest  in, the Receivables to any and all Customers or any

11.   LENDERS'  RIGHTS  AND  REMEDIES  AFTER  DEFAULT.
      -----------------------------------------------

     11.1.  RIGHTS  AND  REMEDIES.

          Upon  the  occurrence  of (i) an Event of Default pursuant to Sections
10.7  or  10.9  hereof, all Obligations shall be immediately due and payable and
the obligation of Agent and Lenders to make Advances shall be deemed terminated;
and,  (ii)  any  of the other Events of Default and at any time thereafter (such
default not having previously been cured), at the option of Required Lenders all
Obligations  shall be immediately due and payable and the Required Lenders shall
have  the  right  to terminate this Agreement and to terminate the obligation of
Agent and Lenders to make Advances and (iii) a filing of a petition against MSI,
MSUK  or  Sensors  in any involuntary case under any state or federal bankruptcy
laws  (or, as to MSUK, equivalent laws under the laws of England and Wales), the
obligation  of  Agent and Lenders to make Advances hereunder shall be terminated
other  than  as  may be required by an appropriate order of the bankruptcy court
having  jurisdiction over MSI, MSUK or Sensors. Upon the occurrence of any Event
of  Default, Agent shall have the right to exercise any and all other rights and
remedies  provided  for  herein, under the Uniform Commercial Code and at law or
equity  generally,  including,  without  limitation,  the right to foreclose the
security  interests  granted  herein  and  to realize upon any Collateral or any
Subsidiary  Collateral  by  any  available  judicial  procedure  and/or  to take
possession  of  and  sell  any or all of the Collateral or Subsidiary Collateral
with  or  without  judicial  process.  Agent  may  enter any of MSI's, MSUK's or
Sensors'  premises or other premises without legal process and without incurring
liability  to  MSI, MSUK or Sensors therefor, and Agent may thereupon, or at any
time thereafter, in its discretion without notice or demand, take the Collateral
or  Subsidiary  Collateral  and  remove the same to such place as Agent may deem
advisable  and Agent may require MSI, MSUK and Sensors to make the Collateral or
Subsidiary  Collateral available to Agent at a convenient place. With or without
having  the  Collateral  or  Subsidiary Collateral at the time or place of sale,
Agent  may sell the Collateral or Subsidiary Collateral, or any part thereof, at
public  or  private  sale,  at  any time or place, in one or more sales, at such
price  or  prices,  and  upon  such  terms,  either  for  cash, credit or future
delivery,  as  Agent  may  elect.  Except  as  to that part of the Collateral or
Subsidiary  Collateral  which  is perishable or threatens to decline speedily in

                                       72
<PAGE>
value  or is of a type customarily sold on a recognized market, Agent shall give
MSI,  MSUK  and  Sensors reasonable notification of such sale or sales, it being
agreed  that  in  all  events  written notice mailed to MSI, MSUK and Sensors at
least  ten  (10) days prior to such sale or sales is reasonable notification. At
any  public  sale  Agent  may bid for and become the purchaser, and Agent or any
other  purchaser  at  any such sale thereafter shall hold the Collateral and the
Guarantee  Collateral sold absolutely free from any claim or right of whatsoever
kind,  including  any  equity of redemption and such right and equity are hereby
expressly  waived  and  released by MSI, MSUK or Sensors, as the case may be. In
connection  with  the  exercise  of  the  foregoing  remedies,  Agent is granted
permission  to  use  all of MSI's, MSUK's and Sensors' trademarks, trade styles,
trade  names,  patents,  patent  applications,  licenses,  franchises  and other
proprietary  rights  which  are  used  in  connection with (a) Inventory for the
purpose  of  disposing  of  such  Inventory and (b) Equipment for the purpose of
completing  the  manufacture of unfinished goods. The proceeds realized from the
sale  of  any  Collateral  and  any  Subsidiary  Collateral  shall be applied as
follows:  first,  to  the  reasonable  costs,  expenses  and attorneys' fees and
expenses  incurred  by Agent and each Lender for collection and for acquisition,
completion,  protection,  removal,  storage, sale and delivery of the Collateral
and  Subsidiary  Collateral; second, to interest due upon any of the Obligations
and  any  fees payable under this Agreement; and, third, to the principal of the
Obligations.  If any deficiency shall arise, MSI and Sensors shall remain liable
to  Agent  and  Lenders  therefor.

     11.2.  AGENT'S  DISCRETION.

          Agent  shall  have the right in its sole discretion to determine which
rights,  Liens,  security  interests  or  remedies Agent may at any time pursue,
relinquish,  subordinate,  or  modify  or  to take any other action with respect
thereto  and  such  determination  will  not  in any way modify or affect any of
Agent's  or  any  Lender's  rights  hereunder.

     11.3.  SETOFF.

          In addition to any other rights which Agent and Lenders may have under
applicable  law, upon the occurrence of an Event of Default hereunder, Agent and
Lenders  shall  have a right to apply MSI's, MSUK's or Sensors' property held by
Agent  and  such  Lender  to  reduce  the  Obligations.

     11.4.  RIGHTS  AND  REMEDIES  NOT  EXCLUSIVE.

          The  enumeration  of the foregoing rights and remedies is not intended
to  be exhaustive and the exercise of any right or remedy shall not preclude the
exercise  of  any  other  right  or  remedies  provided  for herein or otherwise
provided  by  law,  all  of  which  shall  be  cumulative  and  not alternative.

                                       73

12.  WAIVERS  AND  JUDICIAL  PROCEEDINGS.
     -----------------------------------

     12.1.  WAIVER  OF  NOTICE.

          MSI,  MSUK and Sensors each hereby waives notice of non-payment of any
of the Receivables, demand, presentment, protest and notice thereof with respect
to  any  and  all  instruments,  notice of acceptance hereof, notice of loans or
advances  made, credit extended, Collateral or Subsidiary Collateral received or
delivered,  or  any other action taken in reliance hereon, and all other demands
and  notices  of  any  description,  except  such  as are expressly provided for
herein.

     12.2.  DELAY.

          No delay or omission on Agent's or any Lender's part in exercising any
right,  remedy  or  option shall operate as a waiver of such or any other right,
remedy  or  option  or  of  any  default.

     12.3.  JURY  WAIVER.

          EACH  PARTY  TO  THIS AGREEMENT AND SENSORS HEREBY EXPRESSLY WAIVE ANY
RIGHT  TO  TRIAL  BY  JURY  OF  ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A)
ARISING  UNDER  THIS  AGREEMENT  OR  ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT
EXECUTED  OR  DELIVERED IN CONNECTION HEREWITH, OR (B) IN ANY WAY CONNECTED WITH
OR  RELATED  OR  INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO AND SENSORS OR
ANY  OF THEM WITH RESPECT TO THIS AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR
AGREEMENT  EXECUTED  OR  DELIVERED  IN  CONNECTION HEREWITH, OR THE TRANSACTIONS
RELATED  HERETO  OR  THERETO  IN  EACH  CASE  WHETHER  NOW EXISTING OR HEREAFTER
ARISING,  AND  WHETHER  SOUNDING IN CONTRACT OR TORT OR OTHERWISE AND EACH PARTY
HEREBY  CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE
DECIDED  BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY
FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN
EVIDENCE  OF  THE CONSENTS OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO
TRIAL  BY  JURY.

13.  THE  AGENT.
     ----------

     13.1.  APPOINTMENT.

          Each  Lender  hereby confirms the appointment of the Agent pursuant to
the  Existing  Loan  Agreement  and  hereby irrevocably designates, appoints and
authorizes  First Union National Bank to act as Agent for such Lender under this
Agreement  and to execute and deliver or accept on behalf of each of the Lenders
the  other  Loan  Documents. Each Lender hereby irrevocably authorizes, and each
holder  of  any  Note by the acceptance of a Note shall be deemed irrevocably to
authorize,  the  Agent to take such action on its behalf under the provisions of
this  Agreement and the Other Documents and any other instruments and agreements
referred  to  herein,  and  to  exercise  such powers and to perform such duties

                                       74
<PAGE>
hereunder as are specifically delegated to or required of the Agent by the terms
hereof,  together  with  such powers as are reasonably incidental thereto. First
Union  National  Bank agrees to act as the Agent on behalf of the Lenders to the
extent  provided  in  this Agreement. For purposes of Revolving Advances to MSUK
hereunder,  each  Lender  hereby irrevocably designates, appoints and authorizes
the  London  Branch  to  act  as  sub-agent  for  the Agent. Each Lender further
authorizes  the  London  Branch  to  make  any and all necessary and appropriate
filings  with  the  applicable  office of the United Kingdom Inland Revenue with
respect  to  the  transactions  contemplated hereunder so as to ensure exemption
from  withholding  taxes.

     13.2.  DELEGATION  OF  DUTIES.

          The Agent may perform any of its duties hereunder by or through agents
or  employees  (provided such delegation does not constitute a relinquishment of
its  duties  as Agent) and, subject to Sections 13.5 and 13.6, shall be entitled
to  engage  and  pay for the advice or services of any attorneys, accountants or
other  experts  concerning all matters pertaining to its duties hereunder and to
rely  upon  any  advice  so  obtained.

     13.3.  NATURE  OF  DUTIES;  INDEPENDENT  CREDIT  INVESTIGATION.

          The  Agent  shall  have  no  duties  or  responsibilities except those
expressly  set  forth  in  this  Agreement  and no implied covenants, functions,
responsibilities,  duties,  obligations,  or liabilities shall be read into this
Agreement  or  the  Other  Documents or otherwise exist. The duties of the Agent
shall  be  mechanical  and administrative in nature; the Agent shall not have by
reason  of  this  Agreement  or  the  Other  Documents  a  fiduciary  or  trust
relationship  in  respect  of  any  Lender  (except  to  the extent specifically
required  pursuant  to  the  First  Mortgage  Debenture  and  the  Intercreditor
Agreement);  and  nothing in this Agreement or the Other Documents, expressed or
implied, is intended to or shall be so construed as to impose upon the Agent any
obligations  in  respect  of  this  Agreement  or  the Other Documents except as
expressly  set  forth herein and therein. Without limiting the generality of the
foregoing, the use of the term "agent" in this Agreement and the Other Documents
with  reference  to  the Agent is not intended to connote any fiduciary or other
implied (or express) obligations 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. Each Lender expressly acknowledges (i) that the
Agent  has  not  made any representations or warranties to it and that no act by
the  Agent hereafter taken, including any review of the affairs of MSI, MSUK and
of  Sensors, shall be deemed to constitute any representation or warranty by the
Agent  to  any  Lender; (ii) that it has made and will continue to make, without
reliance  upon  the  Agent,  its  own independent investigation of the financial
condition and affairs and its own appraisal of the creditworthiness of MSI, MSUK
or  of  Sensors in connection with this Agreement and the making and continuance
of  the  Advances hereunder; and (iii) except as expressly provided herein, that
the  Agent  shall  have  no  duty  or  responsibility,  either initially or on a
continuing  basis,  to  provide  any Lender with any credit or other information
with  respect  thereto,  whether coming into its possession before the making of
any  Advance  or  at  any  time  or  times  thereafter.

     13.4.  ACTIONS  IN  DISCRETION  OF  AGENT;  INSTRUCTIONS  FROM THE LENDERS.

          The Agent agrees, upon the written request of the Required Lenders, to
take or refrain from taking any action of the type specified as being within the
Agent's  rights,  powers or discretion herein, provided that the Agent shall not
be  required to take any action which exposes the Agent to personal liability or
which  is contrary to this Agreement or any Other Document or applicable law. In

                                       75
<PAGE>
the  absence  of  a  request  by  the  Required  Lenders,  the  Agent shall have
authority,  in  its  sole  discretion,  to  take or not to take any such action,
unless  this Agreement specifically requires the consent of the Required Lenders
or  all  of  the  Lenders.  Any  action taken or failure to act pursuant to such
instructions  or  discretion shall be binding on the Lenders, subject to Section
13.6.  Subject to the provisions of Section 13.6, no Lender shall have any right
of  action  whatsoever  against  the  Agent  as  a result of the Agent acting or
refraining  from  acting  hereunder  in  accordance with the instructions of the
Required  Lenders,  or  in  the  absence  of  such instructions, in the absolute
discretion  of  the  Agent.

     13.5.  REIMBURSEMENT  AND  INDEMNIFICATION  OF  AGENT  BY  MSI  AND  MSUK.

          MSI  and  MSUK unconditionally agree to pay or reimburse the Agent and
hold  the Agent harmless against (a) liability for the payment of all reasonable
out-of-pocket  costs, expenses and disbursements, including fees and expenses of
counsel  (including  the  allocated  costs  of  staff  counsel),  appraisers and
environmental  consultants,  incurred  by  the  Agent (i) in connection with the
development,  negotiation,  preparation,  printing,  execution,  administration,
syndication,  interpretation  and  performance  of  this Agreement and the Other
Documents,  (ii)  relating  to  any  requested  amendments,  waivers or consents
pursuant  to  the  provisions hereof or the Other Documents, (iii) in connection
with  the  enforcement  of this Agreement or any Other Document or collection of
amounts  due  hereunder or thereunder or the proof and allowability of any claim
arising  under  this  Agreement  or any Other Document, whether in bankruptcy or
receivership  proceedings or otherwise, and (iv) in any workout or restructuring
or  in  connection with the protection, preservation, exercise or enforcement of
any  of  the terms hereof or of any rights hereunder or under any Other Document
or in connection with any foreclosure, collection or bankruptcy proceedings, and
(b)  all  liabilities,  obligations,  losses,  damages,  penalties,  actions,
judgments,  suits,  costs,  expenses  or  disbursements  of  any  kind or nature
whatsoever  which  may be imposed on, incurred by or asserted against the Agent,
in its capacity as such, in any way relating to or arising out of this Agreement
or  any Other Documents or any action taken or omitted by the Agent hereunder or
thereunder,  provided  that  MSI and MSUK shall not be liable for any portion of
such  liabilities,  obligations, losses, damages, penalties, actions, judgments,
suits,  costs,  expenses  or  disbursements if the same results from the Agent's
gross  negligence  or willful misconduct, or if MSI or MSUK was not given notice
of  the subject claim and the opportunity to participate in the defense thereof,
at  its expense (except that MSI and MSUK shall remain liable to the extent such
failure to give notice does not result in a loss to MSI or MSUK), or if the same
results  from  a  compromise  or  settlement  agreement entered into without the
consent  of MSI and MSUK, which shall not be unreasonably withheld. In addition,
MSI and MSUK agree to reimburse and pay all reasonable out-of-pocket expenses of
the  Agent's regular employees and agents engaged periodically to perform audits
of  MSI's  and  MSUK's  books,  records  and  business  properties.

     13.6.  EXCULPATORY  PROVISIONS;  LIMITATION  OF  LIABILITY.

          Neither  the  Agent  nor  any  of  its directors, officers, employees,
agents, attorneys or Affiliates shall (a) be liable to any Lender for any action
taken  or omitted to be taken by it or them hereunder, or in connection herewith
including  pursuant  to  any  Other  Document, unless caused by its or their own
gross  negligence or willful misconduct, (b) be responsible in any manner to any
of  the  Lenders for the effectiveness, enforceability, genuineness, validity or
the  due  execution of this Agreement or any Other Documents or for any recital,
representation, lien warranty, document, certificate, report or statement herein
or  made  or  furnished  under or in connection with this Agreement or any Other
Documents,  or (c) be under any obligation to any of the Lenders to ascertain or

                                       76
<PAGE>
to inquire as to the performance or observance of any of the terms, covenants or
conditions  hereof  or  thereof  on  the  part  of  MSI, MSUK or Sensors, or the
financial  condition  of  MSI,  MSUK  or  Sensors,  or the existence or possible
existence  of  any  Event  of  Default.  No  claim may be made by any MSI, MSUK,
Sensors,  any  Lender, the Agent or any of their respective Subsidiaries against
the Agent, any Lender or any of their respective directors, officers, employees,
agents,  attorneys  or  Affiliates, or any of them, for any special, indirect or
consequential  damages  or,  to  the  fullest  extent  permitted by law, for any
punitive  damages  in  respect of any claim or cause of action (whether based on
contract,  tort, statutory liability, or any other ground) based on, arising out
of  or  related  to  this  Agreement  or  any Other Document or the transactions
contemplated  hereby  or  any  act,  omission  or  event occurring in connection
herewith  or therewith, including the negotiation, documentation, administration
or  collection  of  the  Advances,  and  MSI  (for itself and on behalf of MSUK,
Sensors  and  each  of  its  Subsidiaries),  the Agent and each Lender hereby or
thereby  waive,  releases  and  agree  never  to sue upon any claim for any such
damages, whether such claim now exists or hereafter arises and whether or not it
is now known or suspected to exist in its favor. Each Lender agrees that, except
for  notices,  reports and other documents expressly required to be furnished to
the  Lenders  by the Agent hereunder or given to the Agent for the account of or
with  copies  for  the  Lenders,  the Agent and each of its directors, officers,
employees,  agents,  attorneys  or  Affiliates  shall  not  have  any  duty  or
responsibility  to  provide  any  Lender  with  any  credit or other information
concerning  the  business,  operations,  property,  condition  (financial  or
otherwise), prospects or creditworthiness of MSI, MSUK or Sensors which may come
into  the  possession of the Agent or any of its directors, officers, employees,
agents,  attorneys  or  Affiliates.

     13.7.  REIMBURSEMENT  AND  INDEMNIFICATION  OF  AGENT  BY  LENDERS.

          Each Lender agrees to reimburse and indemnify the Agent (to the extent
not  reimbursed  by  MSI  or MSUK and without limiting the Obligation of MSI and
MSUK  to  do  so)  in  proportion  to  its  Ratable  Share  from and against all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs,  expenses  or  disbursements, including attorneys' fees and disbursements
(including  the  allocated  costs of staff counsel), and costs of appraisers and
environmental consultants, of any kind or nature whatsoever which may be imposed
on,  incurred  by or asserted against the Agent, in its capacity as such, in any
way  relating  to or arising out of this Agreement or any Other Documents or any
action  taken  or omitted by the Agent hereunder or thereunder, provided that no
Lender shall be liable for any portion of such liabilities, obligations, losses,
damages,  penalties, actions, judgments, suits, costs, expenses or disbursements
(a) if the same results from the Agent's gross negligence or willful misconduct,
or  (b)  if  such  Lender  was  not  given  notice  of the subject claim and the
opportunity  to  participate in the defense thereof, at its expense (except that
such  Lender  shall remain liable to the extent such failure to give notice does
not  result  in  a  loss  to  the  Lender),  or  (c)  if the same results from a
compromise  and  settlement  agreement  entered into without the consent of such
Lender,  which  shall  not  be  unreasonably  withheld. In addition, each Lender
agrees promptly upon demand to reimburse the Agent (to the extent not reimbursed
by  MSI  or  MSUK  and  without  limiting  the  Obligation  of  MSI to do so) in
proportion  to its Ratable Share for all amounts due and payable by MSI and MSUK
to  the  Agent in connection with the Agent's periodic audit of MSI's and MSUK's
books,  records  and  business  properties.

<PAGE>
     13.8.  RELIANCE  BY  AGENT.

          The  Agent shall be entitled to rely upon any writing, telegram, telex
or  teletype  message,  resolution,  notice,  consent,  certificate,  letter,
cablegram,  statement,  order  or other document or conversation by telephone or
otherwise believed by it to be genuine and correct and to have been signed, sent
or  made  by  the  proper Person or Persons, and upon the advice and opinions of
counsel  and  other professional advisers selected by the Agent. The Agent shall
be fully justified in failing or refusing to take any action hereunder unless it
shall  first  be  indemnified to its satisfaction by the Lenders against any and
all  liability  and  expense  which may be incurred by it by reason of taking or
continuing  to  take  any  such  action.

     13.9.  NOTICE  OF  DEFAULT.

          The  Agent  shall  not  be  deemed  to have knowledge or notice of the
occurrence  of  any  Default  or  Event of Default unless the Agent has received
written notice from a Lender or MSI referring to this Agreement, describing such
Default  or  Event  of  Default  and  stating  that  such notice is a "notice of
default."

     13.10.  NOTICES.

          The  Agent  shall  send  to each Lender a copy of all notices received
from  MSI  and  MSUK  pursuant  to the provisions of this Agreement or the Other
Documents  promptly  after  receipt thereof. The Agent shall promptly notify MSI
and  the  other  Lenders of each change in the Prime Rate and the effective date
thereof  but  failure to do so shall not effect any change in the interest rates
herein.

     13.11.  LENDERS  IN  THEIR  INDIVIDUAL  CAPACITIES.

          With  respect  to  its  Revolving  Credit  Commitment,  the  Revolving
Advances,  the  Term  Loan Commitment and the Term Loan made by it and any other
rights  and  powers  given to it as a Lender hereunder or under any of the Other
Documents,  the  Agent  shall  have  the same rights and powers hereunder as any
other  Lender and may exercise the same as though it were not the Agent, and the
term  "Lenders" shall, unless the context otherwise indicates, include the Agent
in  its  individual  capacity.  First Union National Bank and its Affiliates and
each  of  the  Lenders and their respective Affiliates may, without liability to
account,  except  as  prohibited  herein,  make  loans to, accept deposits from,
discount drafts for, act as trustee under indentures of, and generally engage in
any  kind of banking or trust business with, MSI and its Affiliates, in the case
of the Agent, as though it were not acting as Agent hereunder and in the case of
each  Lender,  as  though  such  Lender were not a Lender hereunder. The Lenders
acknowledge  that,  pursuant to such activities, the Agent or its Affiliates may
(i) receive information regarding MSI or MSUK (including information that may be
subject  to confidentiality obligations in favor of MSI or MSUK) and acknowledge
that the Agent shall be under no obligation to provide such information to them,
and  (ii)  accept  fees and other consideration from MSI or MSUK for services in
connection  with  this Agreement and otherwise without having to account for the
same  to  the  Lenders.

     13.12.  HOLDERS  OF  NOTES.

          The  Agent  may  deem  and  treat  any  payee of any Note as the owner
thereof  for  all  purposes  hereof  unless  and  until  written  notice  of the
assignment  or  transfer  thereof  shall  have  been  filed  with the Agent. Any

                                       78
<PAGE>
request,  authority  or  consent  of  any  Person who at the time of making such
request  or  giving such authority or consent is the holder of any Note shall be
conclusive  and binding on any subsequent holder, transferee or assignee of such
Note  or  of  any  Note  or  Notes  issued  in  exchange  therefor.

     13.13.  EQUALIZATION  OF  LENDERS.

          The  Lenders  and the holders of any participations in any Notes agree
among themselves that, with respect to all amounts received by any Lender or any
such  holder  for  application  on any Obligation hereunder or under any Note or
under  any  such  participation,  whether  received  by  voluntary  payment,  by
realization  upon  security, by the exercise of the right of set-off or banker's
lien,  by counterclaim or by any other non-pro rata source, equitable adjustment
will  be made in the manner stated in the following sentence so that, in effect,
all  such  excess  amounts  will  be  shared  ratably among the Lenders and such
holders  in proportion to their interests in payments under the Notes, except as
otherwise  provided  in Sections 2.22 or in Article III. The Lenders or any such
holder  receiving any such amount shall purchase for cash from each of the other
Lenders  an interest in such Lender's Advances in such amount as shall result in
a  ratable  participation  by  the Lenders and each such holder in the aggregate
unpaid  amount  under  the  Notes,  provided  that if all or any portion of such
excess  amount is thereafter recovered from the Lender or the holder making such
purchase,  such  purchase  shall be rescinded and the purchase price restored to
the  extent  of  such recovery, together with interest or other amounts, if any,
required  by  law (including court order) to be paid by the Lender or the holder
making  such  purchase.

     13.14.  SUCCESSOR  AGENT.

          The  Agent  (i)  may  resign  as  Agent  or  (ii) shall resign if such
resignation  for  cause  is requested by the Required Lenders (if the Agent is a
Lender,  the  Agent's  Advances  and  its  Commitment  shall  be  considered  in
determining  whether  the  Required Lenders have requested such resignation), in
either  case  of  (i)  or  (ii)  by giving not less than thirty (30) days' prior
written  notice  to  MSI.  If  the Agent shall resign under this Agreement, then
either (a) the Required Lenders shall appoint from among the Lenders a successor
agent  for  the  Lenders,  subject to the consent of MSI, such consent not to be
unreasonably withheld, or (b) if a successor agent shall not be so appointed and
approved  within  the thirty (30) day period following the Agent's notice to the
Lenders  of  its  resignation, then the Agent shall appoint, with the consent of
MSI,  such  consent not to be unreasonably withheld, a successor agent who shall
serve  as Agent until such time as the Required Lenders appoint and MSI consents
to the appointment of a successor agent. Upon its appointment pursuant to either
clause  (a)  or  (b)  above,  such  successor agent shall succeed to the rights,
powers  and  duties of the Agent, and the term "Agent" shall mean such successor
agent, effective upon its appointment, and the former Agent's rights, powers and
duties  as Agent shall be terminated without any other or further act or deed on
the part of such former Agent or any of the parties to this Agreement. After the
resignation  of  any  Agent hereunder, the provisions of this Article XIII shall
inure  to  the  benefit  of such former Agent and such former Agent shall not by
reason  of  such  resignation  be  deemed  to be released from liability for any
actions  taken  or  not  taken by it while it was an Agent under this Agreement.

<PAGE>
     13.15.  AVAILABILITY  OF  FUNDS.

          The  Agent  may  assume  that  each  Lender  has made or will make the
proceeds  of  an Advance available to the Agent unless the Agent shall have been
notified  by  such Lender on or before the later of (1) the close of business on
the Business Day preceding the date of Borrowing with respect to such Advance or
two  (2) hours before the time on which the Agent actually funds the proceeds of
such  Advance  to  MSI  or  MSUK  (whether  using its own funds pursuant to this
Section  13.15  or  using  proceeds  deposited with the Agent by the Lenders and
whether  such  funding  occurs  before  or  after  the time on which Lenders are
required to deposit the proceeds of such Advance with the Agent). The Agent may,
in  reliance upon such assumption (but shall not be required to), make available
to  MSI  or  MSUK a corresponding amount. If such corresponding amount is not in
fact  made available to the Agent by such Lender, the Agent shall be entitled to
recover  such amount on demand from such Lender (or, if such Lender fails to pay
such  amount forthwith upon such demand from MSI or MSUK) together with interest
thereon,  in  respect  of each day during the period commencing on the date such
amount  was  made  available  to  MSI  or  MSUK and ending on the date the Agent
recovers  such  amount,  at a rate per annum equal to (i) the Federal Funds Rate
during  the  first  three (3) days after such interest shall begin to accrue and
(ii)  the  applicable  interest rate in respect of such Advance after the end of
such  three-day  period.

     13.16.  CALCULATIONS.

          In  the  absence  of gross negligence or willful misconduct, the Agent
shall  not be liable for any error in computing the amount payable to any Lender
whether in respect of the Advances, fees or any other amounts due to the Lenders
under  this  Agreement or any Other Document. In the event an error in computing
any amount payable to any Lender is made, the Agent, MSI, MSUK and each affected
Lender  shall,  forthwith upon discovery of such error, make such adjustments as
shall  be  required to correct such error, and any compensation therefor will be
calculated  at  the  Federal  Funds  Rate.

     13.17.  BENEFICIARIES.

          Except  as  expressly  provided herein, the provisions of this Article
XIII  are solely for the benefit of the Agent and the Lenders, and MSI, MSUK and
Sensors  shall  not  have any rights to rely on or enforce any of the provisions
hereof.  In  performing its functions and duties under this Agreement, the Agent
shall  act  solely  as agent of the Lenders and does not assume and shall not be
deemed  to have assumed any obligation toward or relationship of agency or trust
with  or  for  MSI,  MSUK  or  Sensors.

     13.18.  NO  LIABILITY  FOR  FAILURE  TO  MAKE  FILINGS.

          The  Agent in its limited capacity as trustee as specifically required
pursuant  to  the  First  Mortgage  Debenture and the Intercreditor Agreement or
otherwise  shall not be liable for any failure, omission or defect in perfecting
the  security  granted  pursuant to the First Mortgage Debenture or any security
created  thereby including, without limitation, any failure to: (i) register the
same  in accordance with the provisions of any of the documents of title of MSUK
to  any  of the property thereby charged; or (ii) effect or procure registration
of  or  otherwise protect any floating charge or any other such security created
by  the  First  Mortgage  Debenture  under the Land Registration Act 1925 or any
other  registration  laws  in  any  jurisdiction.

                                       80
<PAGE>
     13.19.  ACCEPTANCE  OF  TITLE.

          The  Agent in its limited capacity as trustee as specifically required
pursuant  to  the  First  Mortgage  Debenture and the Intercreditor Agreement or
otherwise may accept without inquiry such title as MSUK may have to the property
secured  pursuant  to  the  First  Mortgage  Debenture.

     13.20.  NO  OBLIGATION  TO  HOLD  TITLE  DEEDS.

          The  Agent in its limited capacity as trustee as specifically required
pursuant  to  the  First  Mortgage  Debenture and the Intercreditor Agreement or
otherwise  shall  not  be  under  any  obligation  to  hold  the  First Mortgage
Debenture, the Intercreditor Agreement, any title deed or any other documents in
connection  therewith  or  any  other  documents  in  connection with the assets
charged  by  the  First Mortgage Debenture or any other such security in its own
possession  or  to take any steps to protect or preserve the same. The Agent may
permit MSUK to retain the First Mortgage Debenture, the Intercreditor Agreement,
any  title  deeds  and any other documents in its possession. The Agent will use
all  reasonable care to ensure the safe custody of the First Mortgage Debenture,
the  Intercreditor  Agreement,  any  title  deeds,  and  other  documents in its
possession  but shall not be liable for the damage or destruction of any of such
documents unless caused by the gross negligence or willful default of the Agent.

     13.21.  TRUSTEE  POWERS.

          Except as otherwise provided in this Agreement and in any of the Other
Documents,  the  Agent,  in  its  limited  capacity  as  trustee as specifically
required  pursuant  to  the  First  Mortgage  Debenture  and  the  Intercreditor
Agreement,  shall  have:  (i)  the benefit of all the provisions of this Article
XIII;  (ii) all the powers of an absolute owner of the security granted pursuant
to  the  First  Mortgage  Debenture;  (iii)  the  power of appointing new and/or
additional  trustees;  and  (iv)  all  of the powers and discretion conferred on
trustees  by  the  Trustee  Act  1925  (to the extent not inconsistent with this
Agreement  and the Other Documents) and on the Agent by this Agreement and Other
Documents (including without limitation the power to invest all monies which are
received by the Agent under the trusts contained in the First Mortgage Debenture
and  the  Intercreditor  Agreement  in  its  name  or  under  its control in any
investment  for  the  time being authorized by English law for the investment by
trustees of trust money or in any other investments which may be selected by the
Agent).  Additionally,  the  Agent  shall have the power to place such monies on
deposit  in its name or under its control at such bank or institution (including
at  the  Agent)  and  on  such  terms  as  the  Agent  may  deem  appropriate.

14.  EFFECTIVE  DATE  AND  TERMINATION.
     ---------------------------------

     14.1.  TERM.

          This  Agreement,  which  shall  inure  to  the benefit of and shall be
binding  upon  the  parties  hereto  and the respective successors and permitted
assigns  of  MSI,  MSUK,  the other Obligors, Agent and Lenders, shall be deemed

     14.2.  TERMINATION.

          The  termination  of the Agreement shall not affect MSI's, MSUK's, any
other  Obligor's,  any  of  Lender's or Agent's rights or any of the Obligations
having  their inception prior to the effective date of such termination, and the
provisions  hereof  shall  continue to be fully operative until all transactions
entered  into,  rights  or  interests  created  or  Obligations  have been fully
disposed  of,  concluded or liquidated. The security interests, Liens and rights
granted  to  Agent  and/or  Lenders hereunder and the financing statements filed

Obligations  of  MSI, MSUK and Sensors have been paid or performed in full after
the  termination of this Agreement or MSI and/or MSUK has furnished Agent and/or
Lenders  with  an  indemnification satisfactory to Lenders with respect thereto.
Accordingly,  MSI,  MSUK  and Sensors waive any rights which each may have under
Section  9-404(1)  of  the  Uniform  Commercial  Code  to  demand  the filing of
termination  statements with respect to the Collateral, and Agent and/or Lenders
shall  not  be  required  to  send  such  termination statements to MSI, MSUK or
Sensors, or to file them with any filing office, unless and until this Agreement
shall have been terminated in accordance with its terms and all Obligations paid
(or  cash  collateralized)  in  full  in  immediately  available  funds.  All
representations,  warranties, covenants, waivers and agreements contained herein
shall  survive termination hereof until all Obligations are paid or performed in
full.

Document or the rights of the Lenders or MSI or MSUK hereunder or thereunder, or
may grant written waivers or consents to a departure from the due performance of
the  Obligations  of  MSI  and MSUK hereunder or thereunder. Any such agreement,
waiver  or consent made with such written consent shall be effective to bind all
the Lenders and MSI and MSUK; provided, that, without the written consent of all
the  Lenders,  no  such  agreement,  waiver  or  consent may be made which will:

issuance  of Letters of Credit shall be effective without the written consent of
the  Agent.

     15.2.  NO  IMPLIED  WAIVERS;  CUMULATIVE  REMEDIES;  WRITING  REQUIRED.

          No  course  of  dealing  and  no  delay or failure of the Agent or any
Lender  in exercising any right, power, remedy or privilege under this Agreement
or  any  Other  Document  shall  affect  any other or future exercise thereof or
operate as a waiver thereof, nor shall any single or partial exercise thereof or
any  abandonment  or  discontinuance  of  steps  to enforce such a right, power,
remedy or privilege preclude any further exercise thereof or of any other right,
power, remedy or privilege. The rights and remedies of the Agent and the Lenders
under this Agreement and any Other Documents are cumulative and not exclusive of
any  rights  or  remedies  which  they would otherwise have. Any waiver, permit,
consent  or  approval  of any kind or character on the part of any Lender of any
breach  or  default  under this Agreement or any such waiver of any provision or
condition  of  this  Agreement must be in writing and shall be effective only to
the  extent specifically  set  forth  in  such  writing.

     15.3.  REIMBURSEMENT AND INDEMNIFICATION OF LENDERS BY MSI AND MSUK; TAXES.

          MSI  and MSUK agree unconditionally upon demand to pay or reimburse to
each  Lender (other than the Agent, as to which MSI's and MSUK's Obligations are
set  forth  in  Section  13.5)  and  to  save  such  Lender harmless against (i)
liability  for  the  payment of all reasonable out-of-pocket costs, expenses and
disbursements (including fees and expenses of counsel (including allocated costs
of  staff  counsel)  for  each Lender) except with respect to (a) and (b) below,
incurred  by  such  Lender  (a)  in  connection  with  the  administration  and
interpretation  of  this  Agreement,  and  other instruments and documents to be
delivered  hereunder,  (b)  relating  to  any  amendments,  waivers  or consents
pursuant  to  the  provisions  hereof, (c) in connection with the enforcement of
this  Agreement or any Other Document, or collection of amounts due hereunder or
thereunder  or  the  proof  and  allowability  of  any  claim arising under this
Agreement  or  any  Other  Document,  whether  in  bankruptcy  or  receivership
proceedings  or  otherwise,  and  (d)  in  any  workout  or  restructuring or in
connection  with the protection, preservation, exercise or enforcement of any of
the  terms  hereof  or of any rights hereunder or under any Other Document or in
connection  with  any foreclosure, collection or bankruptcy proceedings, or (ii)
all  liabilities,  obligations,  losses, damages, penalties, actions, judgments,
suits,  costs,  expenses or disbursements of any kind or nature whatsoever which

                                       83
<PAGE>
may  be imposed on, incurred by or asserted against such Lender, in its capacity
as  such,  in  any way relating to or arising out of this Agreement or any Other
Documents or any action taken or omitted by such Lender hereunder or thereunder,
provided  that  MSI  and  MSUK  shall  not  be  liable  for  any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs,  expenses  or  disbursements  (A)  if the same results from such Lender's
gross  negligence  or  willful misconduct, or (B) if MSI was not given notice of
the  subject claim and the opportunity to participate in the defense thereof, at
its  expense  (except  that  MSI and MSUK shall remain liable to the extent such
failure  to give notice does not result in a loss to MSI or MSUK), or (C) if the
same  results from a compromise or settlement agreement entered into without the
consent  of  MSI,  which  shall  not  be unreasonably withheld. The Lenders will
attempt to minimize the fees and expenses of legal counsel for the Lenders which
are  subject  to  reimbursement by MSI hereunder by considering the usage of one
law  firm  to  represent  the  Lenders  and  the  Agent if appropriate under the
circumstances.  MSI  and  MSUK agree unconditionally to pay all stamp, document,
transfer,  recording  or  filing  taxes  or  fees and similar impositions now or
hereafter determined by the Agent or any Lender to be payable in connection with
this  Agreement or any Other Document, and MSI and MSUK agree unconditionally to
save  the Agent and the Lenders harmless from and against any and all present or
future  claims,  liabilities  or  losses  with  respect to or resulting from any
omission  to  pay  or  delay  in  paying  any  such  taxes, fees or impositions.

     15.4.  HOLIDAYS.

          Whenever  payment of an Advance to be made or taken hereunder shall be
due  on  a day which is not a Business Day such payment shall be due on the next
Business  Day and such extension of time shall be included in computing interest
and fees, except that (a) all outstanding Revolving Advances shall be due on the
Business  Day  preceding  the  Expiration  Date  if the Expiration Date is not a
Business  Day,  and (b) the Term Loan shall be due on the Business Day preceding
the  Term  Loan  Maturity  Date if the Term Loan Maturity Date is not a Business
Day.  Whenever  any  payment or action to be made or taken hereunder (other than
payment of the Revolving Advance and the Term Loan) shall be stated to be due on
a day which is not a Business Day, such payment or action shall be made or taken
on  the next following Business Day (except as provided with respect to Interest
Periods  under  the  LIBOR  Rate Loans), and such extension of time shall not be
included  in computing interest or fees, if any, in connection with such payment
or  action.

     15.5.  FUNDING  BY  BRANCH,  SUBSIDIARY  OR  AFFILIATE.

          (a) Each Lender shall have the right from time to time, without notice
to  MSI  or  MSUK,  to  deem  any branch, Subsidiary or Affiliate (which for the
purposes of this Section 15.5 shall mean any corporation or association which is
directly  or  indirectly  controlled  by  or  is under direct or indirect common
control  with  any  corporation  or  association  which  directly  or indirectly
controls  such  Lender)  of  such  Lender to have made, maintained or funded any
LIBOR  Rate  Loan  at  any  time,  provided  that  immediately following (on the
assumption  that a payment were then due from MSI or MSUK to such other office),
and  as  a  result  of  such  change, MSI or MSUK would not be under any greater
financial obligation pursuant to Sections 2.2(g), 3.5 and 3.7 than it would have
been  in the absence of such change. Notional funding offices may be selected by
each  Lender  without  regard  to  such  Lender's  actual  methods  of  making,
maintaining  or  funding the Advances or any sources of funding actually used by
or  available  to  such  Lender.

          (b)  Each  Lender  shall  have  the right from time to time to make or
maintain  any Advance by arranging for a branch, Subsidiary or Affiliate of such
Lender  to  make  or  maintain such Advance subject to the last sentence of this
Section  15.5(b). If any Lender causes a branch, Subsidiary or Affiliate to make
or maintain any part of the Advances hereunder, all terms and conditions of this
Agreement  shall,  except  where  the  context  clearly  requires  otherwise, be

                                       84
<PAGE>
applicable  to  such part of the Advances to the same extent as if such Advances
were  made  or maintained by such Lender, but in no event shall any Lender's use
of  such  a  branch, Subsidiary or Affiliate to make or maintain any part of the
Advances  hereunder cause such Lender or such branch, Subsidiary or Affiliate to
incur  any  cost  or expenses payable by MSI or MSUK hereunder or require MSI or
MSUK  to  pay  any  other  compensation  to  any  Lender (including any expenses
incurred  or  payable  pursuant  to  Sections  2.2(g),  3.5 and 3.7) which would
otherwise  not  be  incurred.

     15.6.  GOVERNING  LAW.

          This  Agreement shall be deemed a contract under and shall be governed
by and construed in accordance with the laws of the State of New Jersey, without
giving  effect  to  the  principles of conflicts of law. Any judicial proceeding
brought  by  or  against MSI, MSUK or another Obligor with respect to any of the
Obligations, this Agreement or any Other Document may be brought in any court of
competent  jurisdiction  in  the  State of New Jersey, United States of America,
and,  by  execution  and  delivery  of  this  Agreement, MSI, MSUK and the other
Obligors  accept  for  themselves  and  in  connection  with  their  properties,
generally  and  unconditionally, the non-exclusive jurisdiction of the aforesaid
courts,  and  irrevocably agrees to be bound by any judgment rendered thereby in
connection  with  this  Agreement. MSI, MSUK and the other Obligors hereby waive
personal  service  of  any  and  all process upon them and consent that all such
service  of  process  may  be made by registered mail (return receipt requested)
directed  to  MSI,  MSUK  and  the  other Obligors at MSI's address set forth in
Schedule  15.9 and service so made shall be deemed completed five (5) days after
the  same  shall  have  been  so  deposited in the mails of the United States of
America, and MSUK hereby appoints MSI as its agent for service of process in the
United States of America. Nothing herein shall affect the right to serve process
in  any  manner permitted by law or shall limit the right of Agent or any Lender
to bring proceedings against MSI, MSUK or any other Obligor in the courts of any
other  jurisdiction.  MSI,  MSUK  and  the other Obligors waive any objection to
jurisdiction  and  venue of any action instituted hereunder and shall not assert
any  defense  based  on  lack  of  jurisdiction or venue or based upon forum non
conveniens.  Any  judicial  proceeding by MSI, MSUK or any other Obligor against
Agent  or  Lenders involving, directly or indirectly, any matter or claim in any
way  arising  out  of,  related to or connected with this Agreement or any Other
Document, shall be brought only in a federal or state court located in the State
of  New  Jersey.  Each Letter of Credit and Section 2.14 shall be subject to the
Uniform  Customs  and  Practice  for  Documentary  Credits  (1998  Revision),
International  Chamber  of  Commerce  Publication  No.  500,  as the same may be
revised  or  amended  from  time  to  time,  and  to the extent not inconsistent
therewith,  the  internal  laws of the State of New Jersey without regard to its
conflict  of  laws  principles, except that each Letter of Credit denominated in
Pounds  Sterling  shall be governed by and construed in accordance with the laws
of  England  and  Wales,  without  regard  to  its  conflict of laws principles.

     15.7.  ENTIRE  UNDERSTANDING.

          This  Agreement  and  the  documents  executed  concurrently  herewith
contain  the  entire understanding among MSI, MSUK, Sensors, the other Obligors,
Agent  and  Lenders  and  supersedes all prior agreements and understandings, if
any,  relating  to  the  subject  matter  hereof. Any promises, representations,
warranties or guarantees not herein contained and hereinafter made shall have no

                                       85
<PAGE>
force  and  effect  unless  in  writing, signed by MSI, MSUK, Sensors, Agent and
Lender's  respective  officers.  Neither  this  Agreement  nor  any  portion  or
provisions  hereof  may  be  changed,  modified,  amended, waived, supplemented,
discharged, canceled or terminated orally or by any course of dealing, or in any
manner other than by an agreement in writing, signed by the party to be charged.
MSI,  MSUK  and  Sensors  acknowledge  that  each has been advised by counsel in
connection  with  the execution of this Agreement and Other Documents and is not
relying  upon oral representations or statements inconsistent with the terms and
provisions  of  this  Agreement.

     15.8.  SUCCESSORS  AND  ASSIGNS;  PARTICIPATIONS;  NEW  LENDERS.

          (a)  This  Agreement  shall  be  binding  upon  and shall inure to the
benefit  of  the  Lenders, the Agent, MSI, MSUK, Sensors, the other Obligors and
their respective successors and assigns, except that MSI and MSUK may not assign
or  transfer  any  of  their  respective rights and Obligations hereunder or any
interest  herein.  Each Lender may, at its own cost, make assignments of or sell
participations in all or any part of its Commitments and the Advances made by it
to  one  or  more banks or other entities, subject to the consent of MSI and the
Agent  with  respect  to  any  assignee,  such  consent  not  to be unreasonably
withheld,  provided  that (1) no consent of any Obligor shall be required (A) if
an  Event  of  Default  exists  and  is  continuing,  or  (B)  in the case of an
assignment by a Lender to an Affiliate of such Lender, and (2) any assignment by
a  Lender  to a Person other than an Affiliate of such Lender may not be made in
amounts  less  than  the  lesser  of  $5,000,000  or the amount of the assigning
Lender's  Commitment. In the case of an assignment, upon receipt by the Agent of
the  Assignment and Assumption Agreement, the assignee shall have, to the extent
of  such  assignment  (unless  otherwise  provided  therein),  the  same rights,
benefits  and  obligations  as  it  would have if it had been a signatory Lender
hereunder,  the Commitments shall be adjusted accordingly, and upon surrender of
any  Revolving Credit Notes or Term Notes subject to such assignment, MSI and/or
MSUK  shall  execute and deliver new Revolving Credit Notes or Term Notes to the
assignee  in an amount equal to the amount of the Revolving Credit Commitment or
Term  Loan  assumed  by it and a new Revolving Credit Notes or Term Notes to the
assigning  Lender  in an amount equal to the Revolving Credit Commitment or Term
Loan  retained  by  it  hereunder.  Any  Lender  which assigns any or all of its
Commitment or Loans to a Person other than an Affiliate of such Lender shall pay
to  the  Agent a service fee in the amount of $3,000 for each assignment. In the
case of a participation, the participant shall only have the rights specified in
Section  11.3  (the  participant's rights against such Lender in respect of such
participation  to be those set forth in the agreement executed by such Lender in
favor  of  the participant relating thereto and not to include any voting rights
except  with  respect to changes of the type referenced in Section 15.1) and all
of  such  Lender's  obligations under this Agreement or any Other Document shall
remain  unchanged, and all amounts payable by MSI, MSUK and Sensors hereunder or
thereunder  shall  be  determined  as  if  such  Lender  had  not  sold  such
participation.

          (b)  Any  assignee  or participant which is not incorporated under the
Laws of the United States of America or a state thereof shall deliver to MSI and
MSUK  and  the Agent the form of certificate described in Section 15.18 relating
to  federal  income  tax  withholding.  Each  Lender  may  furnish  any publicly
available  information  concerning  MSI  or  its  Subsidiaries  and  any  other
information  concerning MSI or its Subsidiaries in the possession of such Lender
from time to time to assignees and participants (including prospective assignees
or  participants),  provided  that  such  assignees and participants agree to be
bound  by  the  provisions  of  Section  15.18.

                                       86
<PAGE>
          (c)  Notwithstanding any other provision in this Agreement, any Lender
may at any time pledge or grant a security interest in all or any portion of its
rights  under  this  Agreement,  its Note and the Other Documents to any Federal
Reserve  Bank  in  accordance  with  Regulation  A  of  the FRB or U.S. Treasury
Regulation  31  CFR  Section 203.14 without notice to or consent of MSI, MSUK or
the  Agent.  No  such  pledge  or grant of a security interest shall release the
transferor  Lender  of  its  obligations  hereunder or under any Other Document.

     15.9.  NOTICES.

          Any  notice,  request,  demand,  direction or other communication (for
purposes  of this Section 15.9 only, a "Notice") to be given to or made upon any
party  hereto  under  any  provision of this Agreement shall be given or made by
telephone  or  in  writing in accordance with this Section 15.9. Any such Notice
must  be delivered to the applicable parties hereto at the addresses and numbers
set  forth  under this respective names on Schedule 15.9 hereof or in accordance
with  any  subsequent  unrevoked  Notice  from  any  such party that is given in
accordance  with  this  Section  15.9.  Any  Notice  shall  be  effective:

          (a)  In  the  case  of  hand-delivery,  when  delivered;

          (b)  If  given  by mail, four days after such Notice is deposited with
the  United  States  Postal  Service,  with  first-class postage prepaid, return
receipt  requested;

          (c)  In  the case of a telephonic Notice, when a party is contacted by
telephone,  if  delivery of such telephone Notice is confirmed no later than the
next  Business  Day by hand delivery, a facsimile or electronic transmission, or
an  overnight  courier  delivery of a confirmatory Notice (received at or before
noon  on  such  next  Business  Day);

          (d)  In  the  case  of  a  facsimile  transmission,  when  sent to the
applicable  party's  facsimile  machine'  telephone number, if the party sending
such Notice receives confirmation of the delivery thereof from its own facsimile
machine;  and

          (e) If given by any other means (including by overnight courier), when
actually  received. Any Lender giving a Notice to MSI or MSUK shall concurrently
send  a copy thereof to the Agent, and the Agent shall promptly notify the other
Lenders  of  its  receipt  of  such  Notice.

     15.10.  SURVIVAL.

          The  obligations of MSI, MSUK and/or the other Obligors under Sections
2.2(f),  2.2(g),  2.12, 2.14, 2.20, 3.6, 3.7, 4.19(h), 13.5, 13.6, 13.7 and 15.3
shall  survive termination of this Agreement and the Other Documents and payment
in  full  of  the  Obligations.

     15.11.  SEVERABILITY.

          If any part of this Agreement is contrary to, prohibited by, or deemed
invalid  under  applicable  laws  or  regulations,  such  provision  shall  be
inapplicable  and  deemed  omitted  to  the  extent  so  contrary, prohibited or
invalid,  but the remainder hereof shall not be invalidated thereby and shall be
given  effect  so  far  as  possible.

     15.12.  INJUNCTIVE  RELIEF.

          MSI,  MSUK  and  the  other Obligors recognize that, in the event MSI,
MSUK  or  another  Obligor  fails  to  perform,  observe or discharge any of its
obligations  or liabilities under this Agreement, any remedy at law may prove to
be inadequate relief to Agent or Lender; therefore, Agent or Lender, if Agent or

                                       87
<PAGE>
Lender  so  requests,  shall  be  entitled to temporary and permanent injunctive
relief in any such case without the necessity of proving that actual damages are
not  an adequate  remedy.

     15.13.  CAPTIONS.

          The  captions  at  various  places  in this Agreement are intended for
convenience  only  and do not constitute and shall not be interpreted as part of
this  Agreement.

     15.14.  COUNTERPARTS;  TELECOPIED  SIGNATURES.

          This  Agreement  may  be  executed  in  any number of and by different
parties  hereto  on separate counterparts, all of which, when so executed, shall
be  deemed  an  original, but all such counterparts shall constitute one and the
same  agreement.  Any  signature  delivered by a party by facsimile transmission
shall  be  deemed  to  be  an  original  signature  hereto.

     15.15.  CONSTRUCTION.

          The  parties acknowledge that each party and its counsel have reviewed
this  Agreement  and that the normal rule of construction to the effect that any
ambiguities  are to be resolved against the drafting party shall not be employed
in the interpretation of this Agreement or any amendments, schedules or exhibits
thereto.

     15.16.  CONFIDENTIALITY;  SHARING  INFORMATION.

          (a)  Agent,  each  Lender and each assignee of a Lender shall hold all
non-public information obtained by Agent, such Lender, or such assignee pursuant
to  the requirements of this Agreement in accordance with Agent's, such Lender's
and  such  assignee's customary procedures for handling confidential information
of  this  nature; provided, however, Agent, Lender and each assignee of a Lender
may  disclose  such  confidential  information (a) to its examiners, affiliates,
outside  auditors,  counsel  and  other  professional advisors, (b) to Agent, to
Lender or to any prospective assignee of a Lender or participant in any Advance,
and  (c) as required or requested by any Official Body or representative thereof
or  pursuant  to  legal  process; provided, further that (i) unless specifically
prohibited  by applicable law or court order, Agent, Lender and each assignee of
a  Lender  shall use its best efforts prior to disclosure thereof, to notify MSI
or  MSUK of the applicable request for disclosure of such non-public information
(A) by a Official Body or representative thereof (other than any such request in
connection  with  an  examination  of  the  financial condition of a Lender or a
Transferee  by  such Official Body) or (B) pursuant to legal process and (ii) in
no  event  shall  Lender, any Lender or any assignee of a Lender be obligated to
return  any  materials  furnished  by MSI or MSUK other than those documents and
instruments in possession of Agent or any Lender in order to perfect its Lien on
the  Collateral  once  the Obligations have been paid in full and this Agreement
has  been  terminated.

          (b)  MSI,  MSUK  and  the other Obligors acknowledge that from time to
time financial advisory, investment banking and other services may be offered or
provided  to  MSI  or  one  or  more  of its Affiliates (in connection with this
Agreement  or  otherwise) by Agent and Lenders or by one or more Subsidiaries or
Affiliates  of  Agent  and  Lenders  and MSI, MSUK and the other Obligors hereby
authorize  Agent  and  Lenders  to  share any information delivered to Agent and

                                       88
<PAGE>
Lenders by MSI and its Subsidiaries pursuant to this Agreement, or in connection
with the decision of Lender to enter into this Agreement, to any such Subsidiary
or  Affiliate  of Agent and Lender, it being understood that any such Subsidiary
or  Affiliate  of  Agent and Lender receiving such information shall be bound by
the  provision  of  this  Section  15.16  as if it were a Lender hereunder. Such
authorization  shall  survive  the  repayment  of  the other Obligations and the
termination  of  the  Agreement.

     15.17.  PUBLICITY.

          MSI  and  MSUK  hereby  authorizes  Agent  to  make  appropriate
announcements,  with  prior  notice to MSI, of the financial arrangement entered
into  between  MSI,  MSUK,  Sensors,  Agent  and  Lenders,  including,  without
limitation,  announcements  which  are  commonly  known  as  tombstones, in such
publications  and  to  such  selected  parties  as  Agent  shall in its sole and
absolute  discretion  deem  appropriate.

     15.18.  TAX  WITHHOLDING  CLAUSE.

          Each  Lender  or  assignee  or  participant  of  a  Lender that is not
incorporated  under  the Laws of the United States of America or a state thereof
agrees  that  it  will deliver to MSI, MSUK and the Agent two (2) duly completed
copies of the following: (i) Internal Revenue Service Form W-9, 4224 or 1001, or
other  applicable  form  prescribed  by the Internal Revenue Service, certifying
that  such Lender, assignee or participant is entitled to receive payments under
this  Agreement  and the Other Documents without deduction or withholding of any
United  States federal income taxes, or is subject to such tax at a reduced rate
under  an  applicable  tax  treaty, or (ii) Internal Revenue Service Form W-8 or
other  applicable  form or a certificate of such Lender, assignee or participant
indicating that such exemption or reduced rate is allowable with respect to such
payments.  Each Lender, assignee or participant required to deliver to MSI, MSUK
and  the  Agent  a  form or certificate pursuant to the preceding sentence shall
deliver  such  form  or certificate as follows: (A) each Lender which is a party
hereto  on the Closing Date shall deliver such form or certificate at least five
(5)  Business  Days  prior  to  the first date on which any interest or fees are
payable  by  MSI  or  MSUK  hereunder  for  the account of such Lender; (B) each
assignee or participant shall deliver such form or certificate at least five (5)
Business  Days  before  the  effective  date of such assignment or participation
(unless  the  Agent  in  its  sole  discretion  shall  permit  such  assignee or
participant to deliver such form or certificate less than five (5) Business Days
before  such  date  in  which  case it shall be due on the date specified by the
Agent).  Each Lender, assignee or participant which so delivers a Form W-8, W-9,
4224  or  1001  further undertakes to deliver to each of MSI, MSUK and the Agent
two  (2)  additional  copies of such form (or a successor form) on or before the
date  that  such form expires or becomes obsolete or after the occurrence of any
event  requiring  a  change in the most recent form so delivered by it, and such
amendments  thereto  or  extensions  or  renewals  thereof  as may be reasonably
requested  by  MSI,  MSUK  or  the  Agent,  either  certifying that such Lender,
assignee or participant is entitled to receive payments under this Agreement and
the  Other  Documents  without  deduction  or  withholding  of any United States
federal  income  taxes  or  is  subject  to  such tax at a reduced rate under an
applicable  tax  treaty  or  stating  that  no such exemption or reduced rate is
allowable.  The Agent shall be entitled to withhold United States federal income
taxes  at  the  full withholding rate unless the Lender, assignee or participant
establishes  an exemption or that it is subject to a reduced rate as established
pursuant  to  the  above  provisions.

                                       89
<PAGE>
     15.19.  APPLICATION  OF  PAYMENTS.

          Agent  shall  have  the  continuing  and  exclusive  right to apply or
reverse  and  reapply any payment and any and all proceeds of Collateral and the
Subsidiary Collateral to any portion of the Obligations. To the extent that MSI,
MSUK  and/or Sensors makes a payment or Agent or any Lender receives any payment
or  proceeds of the Collateral or the Subsidiary Collateral for MSI's, MSUK's or
Sensors'  benefit, which are subsequently invalidated, declared to be fraudulent
or  preferential,  set  aside  or  required to be repaid to a trustee, debtor in
possession,  receiver,  custodian  or  any other party under any bankruptcy law,
common  law  or  equitable  cause, then, to such extent, the Obligations or part
thereof  intended  to  be  satisfied  shall  be  revived and continue as if such
payment  or  proceeds  had  not  been  received  by  Agent  or  such  Lender.

     15.20.  REAFFIRMATION  OF  OBLIGATIONS;  NO  DEFENSES.

          By  executing  this  Agreement,  MSI does hereby represent and warrant
that  as  of  the  date hereof: (i) (A) there is outstanding under the Revolving
Credit  Notes,  the  aggregate principal sum of $14,200,000.36, plus accrued and
                                                                ----
unpaid  interest thereon, (B) there are currently $5,500.00 of Letters of Credit
Outstanding and  60,000 outstanding under the Duty Deferment Bond; and (C) there
is  outstanding  under  the  Term  Notes,  the  aggregate  principal  sum  of
$23,000,000.00,  plus  accrued  and  unpaid  interest thereon; and (ii) all such
                 ----
amounts are owing to the Lenders without defense, offset or counterclaim against
the  Lenders  in  connection with any of the Obligations hereunder or any of the
Other  Documents,  as  any  of the same has been amended, restated, confirmed or
modified.

     15.21.  NET  PAYMENTS

          All  payments  made by MSI and MSUK hereunder and under the Notes will
be  made without setoff, counterclaim or other defense and will be made free and
clear of, and without deduction or withholding for, any present or future taxes,
levies,  imposts,  duties, fees, assessments or other charges of whatever nature
now  or hereafter imposed by any jurisdiction or by any political subdivision or
taxing  authority  thereof  or  therein  with  respect  to  such  payments  (but
excluding, except as provided in the second succeeding sentence, any tax imposed
on  or  measured  by the net income, net profits or gross receipts of any Lender
and  any  taxes imposed solely on deposits or net assets of any Lender), and all
interest,  penalties  or  similar  liabilities with respect to such non-excluded
taxes,  levies,  imposts,  duties,  fees, assessments or other charges (all such
non-excluded  taxes, levies, imposts, duties, fees, assessments or other charges
being  referred  to  collectively  as "Non-Excluded Taxes"). If any Non-Excluded
Taxes  are  so levied or imposed, MSI or MSUK, as applicable, shall pay the full
amount  of  such  Non-Excluded  Taxes  and  such  additional  amounts  as may be
necessary so that every payment of all amounts due under this Agreement or under
any  Note,  after withholding or deduction for or on account of any Non-Excluded
Taxes,  will not be less than the amount provided for herein or in such Note. If
any  amounts  are  payable  in  respect  of  Non-Excluded  Taxes pursuant to the
preceding  sentence, MSI or MSUK, as applicable, shall reimburse the Agent, upon
the  written  request  of the Agent, for taxes imposed on or measured by the net
income,  net  profits or gross receipts of any Lender and for any withholding of
taxes  as  such  Lender  shall  determine  is payable by, or withheld from, such

                                       90
<PAGE>
Lender,  in  respect  of  such  amounts  so  paid to or on behalf of such Lender
pursuant  to  the preceding sentence and in respect of any amounts paid to or on
behalf  of  such  Lender  pursuant to this sentence. MSI or MSUK, as applicable,
shall  furnish  to  the  Agent  within 45 days after the date the payment of any
Non-Excluded  Taxes  is  due  pursuant to applicable law certified copies of tax
receipts  evidencing such payment by MSI or MSUK, as applicable. MSI or MSUK, as
applicable, shall indemnify and hold the Lenders harmless against, and reimburse
the  Lenders  upon  written request for, the amount of any Non-Excluded Taxes so
levied  or  imposed  and paid by any Lender. The provisions hereof shall survive
the  final  payment  of the Obligations. No additional amount will be payable by
MSUK  to  a  Lender  (or  to  the Agent on a Lender's behalf) under this section
unless  it  is  a  Qualifying  Lender  (unless the reason it is not a Qualifying
Lender is by reason of change in a law, regulation, treaty or official directive
or request or a change in the interpretation or application thereof by any court
or  regulatory  authority  having  jurisdiction  over  such  Lender).

     15.22.  JUDGMENTS  AGAINST  MSUK

          In  the  event that Agent and/or the Lenders obtain a judgment against
MSUK  arising  out  of  or  in  connection  with this Agreement in Dollars, such
judgment shall be satisfied in Dollars or in Pounds Sterling in an amount which,
upon  receipt  by  the Lenders, shall be the real equivalent (after any exchange
commissions)  of  the  Dollar  amount  of  such  judgment,  as determined by the
currency  conversion  provisions  set  forth  in  Section  2.25  hereof.

     15.23.  MANDATORY  COSTS  RATE  FORMULAE

          (a)  The  Mandatory Costs Rate, to compensate the Lenders for the cost
attributable  to  the MSUK Sublimit, or other sum denominated in Pounds Sterling
(or  any other currency, where applicable) for any period for which such cost is
to  be  computed under this Agreement resulting from the imposition from time to
time  under  or  pursuant  to the Bank of England Act 1998 and/or by the Bank of
England  and/or  by the Financial Services Authority of a requirement or request
to  place  non  interest-bearing  deposits  or  Special Deposits (as hereinafter
defined),  whether  interest-bearing or not, with the Bank of England and/or pay
fees  to the Financial Services Authority calculated by reference to liabilities
used  to fund the MSUK Sublimit or other sum, will be the rate determined by the
Agent  (rounded  upwards,  if  necessary,  to  four  decimal places) as the rate
resulting  from  the  application  (as appropriate) of the following formulae by
reference  to the circumstances existing on the first day of the relevant period
and for the duration of such period (but with respect to a period of longer than
three  (3)  months,  on  a  three  (3)  monthly  basis  during  such  period):

     In relation to Pounds Sterling Advances or sums:     XL + S(L-D) + F x 0.01
                                                          ----------------------
                                                            100  -  (X  +  S)

     In  relation  to  other  Advances  or  sums:           F  x  0.01
                                                           ------------
                                                                300

Where,  in  each  case,  on  the  day  of  application  of  a  formula:

"X"  is  the amount required to be maintained by the Agent and/or the Lenders on
current  account  with the Bank of England expressed as a percentage of Eligible
Liabilities  (as  hereinafter  defined),  assuming  these to be in excess of any
stated  minimum;

                                       91
<PAGE>
"L"  is the offered quotation of the Agent for one month or, as the case may be,
two or three month Pounds Sterling deposits in the London Interbank Market at or
about  11.00  a.m.  on  the  relevant  quotation  day;

"S"  is  the  amount  of Special Deposits required to be maintained by the Agent
with  the  Bank  of  England  expressed as a percentage of Eligible Liabilities;

"D"  is  the  rate  of interest paid by the Bank of England on Special Deposits;

"F"  is  the  rate  of  charge  payable  by  the Agent and/or the Lenders to the
Financial  Services  Authority pursuant to paragraphs 2.02 or paragraph 2.03 (as
the  case may be) of the Fees Regulations (as hereinafter defined), but for this
purpose the figure at paragraph 2.02b or paragraph 2.03b (as the case may be) of
the  Fees  Regulations  shall  be  deemed  to  be  zero, and expressed in Pounds
Sterling  per  1,000,000  of  the Fee Base (as hereinafter defined) of the Agent
and/or  the  Lenders;  and

"X", "L", "S" and "D" are to be expressed in the relevant formula as numbers and
not  as percentages per annum, and any negative result obtained from subtracting
"D"  from  "L"  shall  be  counted  as  zero.

          (b)     For  the  purposes  of  this  Section:

               (i)     References to the "Bank of England" and to the "Financial
Services  Authority" include, in each case, any other governmental or regulatory
authorities or agencies for the time being serving the same or similar functions
as  the Bank of England and/or the Financial Services Authority, as the case may
be.

               (ii)     The  terms "Eligible Liabilities" and "Special Deposits"
have  the meanings ascribed to them under or pursuant to the Bank of England Act
1998  or  by  the  Bank  of  England  (as  may be appropriate) on the day of the
application  of  the  relevant  formula.

               (iii)     The  term "Fee Base" has the meaning ascribed to it for
the  purposes  of,  and  shall  be  calculated  in  accordance  with,  the  Fees
Regulations.

               (iv)     The  term  "Fees  Regulations"  means,  as  appropriate,
either:     (A)  the  Banking  Supervision  (Fees) Regulations 2000; or (B) such
other regulations as may be in force from time to time in respect of the payment
of  fees  for  banking  supervision.

          (c)     The  Agent  may  from  time  to  time determine and notify the
Borrowers  of  any amendments or variations which are required to be made to the
formulae  set  forth  above  in  order  to  comply  with  any existing or future
requirements  or  requests  from  time to time of the Bank of England and/or the
Financial  Services  Authority  in  relation  to the MSUK Sublimit or other sums
denominated  in Pounds Sterling (including, without limitation, any requirements
or  requests  relating  to  Pounds  Sterling  primary  liquidity)  or  any other
currency,  where applicable, and any such determination shall, in the absence of
manifest  error,  be  conclusive  and  binding.

          WHEREAS,  the  Borrowers,  the  Lenders  and Agent are parties to that
certain  Amended and Restated Revolving Credit, Term Loan and Security Agreement
dated  as  of  February  28, 2001(as same is being and may hereafter be amended,

          WHEREAS,  the  Borrowers have requested and the Lenders have agreed in
order  to  increase  the Revolving Credit Commitment on a temporary basis on the
terms  and  conditions  set  forth  herein.

          IN  CONSIDERATION  of  the  mutual  covenants  and undertakings herein
contained, the parties hereto hereby agree that the Loan Agreement be amended as
follows:

     1.     Article  1  of  the  Loan  Agreement  shall  be  amended so that the
following  new  or  revised  definitions  are  hereby  included  therein:

          "First  Amendment"  shall mean that certain First Amendment to Amended

     2.     The third sentence of Section 2.1(a) of the Loan Agreement is hereby
amended  to  read  as  follows:

          "The  Revolving  Advances shall be evidenced by the secured promissory
          notes  dated  the  date  hereof  from  MSUK  to  each  of  the Lenders
          substantially  in  the  form attached hereto as Exhibit 2.1(a) and the
          restated secured promissory notes dated March 2, 2001 from MSI to each
          of  the  Lenders  substantially  in  the  form  attached  to the First
          Amendment  as  Exhibit  2.1(a)  (the  "Revolving  Credit  Notes").

     3.     Section  2.8  of  the  Loan  Agreement is hereby amended so that the
following  is  added  thereto:

          "The  aggregate  balance  of Advances outstanding on April 30, 2001 in

          Payment  Office  without the necessity of any demand, whether or not a
          Default  or  Event  of  Default  has  occurred."

          4.     By  executing  this  Amendment,  each  of the Borrowers and the
other  Obligors confirms and acknowledges that, as of the date hereof, it has no
defenses, offsets or counterclaims against any of the Obligations under the Loan
Agreement  or  any  of  the Other Documents and that, as of the date hereof, all

Agreement  shall  mean  the  Loan  Agreement,  as amended and reaffirmed by this
Amendment.  All references to the "Obligations" in the Loan Agreement shall mean

and all of the Other Documents, and (iii) after giving effect to this Amendment,

time  or  both  would  constitute  an  Event  of  Default,  has  occurred and is
continuing.

     7.     By  executing this Amendment, the Guarantors confirm and acknowledge
effective  as  of  the  date  hereof,  all  of  the  terms and provisions of the
Guaranties  and  any amendments, renewals, modifications or supplements thereto,
or substitutions therefor, shall remain unchanged and continue in full force and
effect  on  the  date  hereof,  and  by executing this Amendment, the Guarantors
confirm  the  continued  validity  of  such  Guaranties.

no  longer fully accurate or needs updating, such revised or updated Schedule or
Exhibit  shall  be  delivered  to the Lenders concurrently with the execution of
this  Amendment  and  attached  hereto  and shall be deemed to replace the prior

     10.     This Amendment is incorporated by reference into the Loan Agreement
and  the  Other  Documents.  Except  as  otherwise  provided  herein,  all other
provisions  of  the  Loan Agreement and the Other Documents are hereby confirmed
and  ratified  and  shall remain in full force and effect as of the date of this
Amendment

     11.     By  executing  this Amendment, the Obligors confirm and acknowledge
that  the  liens  and  security  interests  granted to the Agent for the ratable

the parties hereto and their heirs, executors, administrators, successors and/or
assigns.

     15.     This  Amendment  shall  be governed by, and construed in accordance
with,  the  laws  of  the  State  of  New  Jersey.

of  its fees and expenses incurred in connection with this Amendment, including,
without limitation, all reasonable attorneys fees and expenses of counsel to the
