                              THE CREDIT FACILITIES

Section 2.1 The Revolving Credit Facility.

            2.1.1 Revolving Credit Facility.

            Subject  to and  upon  the  provisions  of  this  Agreement,  Lender
establishes a revolving  credit facility in favor of Borrower.  The aggregate of
all advances  under the Revolving  Credit  Facility is sometimes  referred to in

            The principal amount of Twenty Five Million Dollars ($25,000,000) is
the "Revolving Credit Committed Amount".


            During the Revolving Credit Commitment Period, Lender agrees to make
advances under the Revolving  Credit  Facility in accordance with the provisions
of this Agreement;  provided that after giving effect to Borrower's request, the
outstanding  principal  balance of the  Revolving  Loan and all Letter of Credit



Obligations  would not exceed the lesser of (a) the Revolving  Credit  Committed
Amount or (b) the then most current Borrowing Base.


            Unless  sooner  paid,  the  unpaid  Revolving  Loan,  together  with
interest accrued and unpaid thereon,  and all other Obligations shall be due and
payable in full on the Revolving Credit Expiration Date.

            2.1.2 Procedure for Making Advances Under the Revolving Loan; Lender
Protection Loans.

            Borrower  may borrow  under the  Revolving  Credit  Facility  on any
Business Day.  Advances  under the Revolving Loan shall be deposited to a demand
deposit  account of Borrower with Lender (or an Affiliate of Lender) or shall be
otherwise applied as directed by Borrower, which direction Lender may require to
be in  writing.  No later  than  12:00  p.m.  (Eastern  Time) on the date of the
requested borrowing,  Borrower shall give Lender oral or written notice (a "Loan
Notice") of the amount and (if requested by Lender) the purpose of the requested
borrowing. Any oral Loan Notice shall be confirmed in writing by Borrower within
three (3)  Business  Days after the making of the  requested  advance  under the
Revolving Loan. Each Loan Notice shall be irrevocable.


            In addition,  Borrower hereby  irrevocably  authorizes Lender at any
time and from time to time,  without further request from or notice to Borrower,
to  make  advances  under  the  Revolving   Loan,  and  to  establish,   without
duplication,  reserves against the Borrowing Base, which Lender, in its sole and
absolute discretion,  deems necessary or appropriate to protect the interests of
Lender, including, without limitation, advances and reserves under the Revolving
Loan made to cover debit balances in the Revolving  Loan Account,  principal of,
and/or  interest on, the Revolving  Loan, the  Obligations  (including,  without
limitation,  any Letter of Credit Obligations),  and/or Enforcement Costs, prior
to,  on,  or after the  termination  of other  advances  under  this  Agreement,
regardless of whether the  outstanding  principal  amount of the Revolving  Loan
that  Lender may  advance or reserve  hereunder  exceeds  the  Revolving  Credit
Committed  Amount or the Borrowing  Base.  Lender shall  communicate to Borrower
from time to time any action  taken  under this  paragraph  either  orally or in
writing.

            2.1.3 Borrowing Base.

            As used in this Agreement,  the term  "Borrowing  Base" means at any
time, an amount equal to the aggregate of (a) eighty percent (80%) of the amount
of Eligible  Receivables  of Borrower,  (b) eighty  percent  (80%) of Borrower's
Unbilled  Receivables  and (c) eighty  percent  (80%) of the amount of  Eligible
Receivables of MXL.


            The Borrowing  Base shall be computed  based on the  Borrowing  Base
Report  most  recently  delivered  to and  accepted  by  Lender  in its sole and
absolute  discretion.  In the event Borrower or MXL fails to furnish a Borrowing
Base Report required by Section 2.1.4  (Borrowing Base Report),  or in the event
Lender believes that a Borrowing Base Report is no longer accurate,  Lender may,
in its sole and  absolute  discretion  exercised  from time to time and  without
limiting its other rights and remedies under this Agreement,  suspend the making
of or limit advances under the Revolving Loan.



            If at any time the total of the  aggregate  principal  amount of the
Revolving  Loan  and  Outstanding  Letter  of  Credit  Obligations  exceeds  the
Borrowing Base, a borrowing base deficiency  ("Borrowing Base Deficiency") shall
exist. Each time a Borrowing Base Deficiency exists,  Borrower,  at the sole and
absolute  discretion  of  Lender  exercised  from  time to time,  shall  pay the
Borrowing Base Deficiency ON DEMAND to Lender.


            Without implying any limitation on Lender's  discretion with respect
to the Borrowing  Base, the criteria for Eligible  Receivables  contained in the
respective  definitions  of  Eligible  Receivables  are in part  based  upon the
business  operations  of Borrower  and MXL existing on or about the Closing Date
and upon information and records  furnished to Lender by Borrower and MXL. If at
any time or from time to time hereafter,  the business operations of Borrower or
MXL change or such  information and records  furnished to Lender is incorrect or
misleading,  Lender  in its  discretion,  may at any time and from  time to time
during the duration of this Agreement  change such criteria or add new criteria.
Lender shall  communicate  such changed or additional  criteria to Borrower from
time to time either orally or in writing.

            2.1.4 Borrowing Base Report.

            Borrower will furnish to Lender no less  frequently than monthly and
at such other times as may be requested by Lender a report of the Borrowing Base
(each a "Borrowing Base Report";  collectively, the "Borrowing Base Reports") in
the form required from time to time by Lender,  appropriately completed and duly
signed.  The Borrowing  Base Report shall contain the amount and payments on the
Receivables,  both billed and unbilled,  and the  calculations  of the Borrowing
Base,  all in  such  detail,  and  accompanied  by  such  supporting  and  other
information,  as Lender may from time to time  request.  Upon  Lender's  request
Borrower and MXL will provide Lender with (a) confirmatory assignment schedules;
(b) copies of Account Debtor invoices; (c) evidence of shipment or delivery; and
(d)  such  further  schedules,   documents  and/or  information   regarding  the
Receivables,  both billed and unbilled,  as Lender may reasonably  require.  The
items to be provided  under this  subsection  shall be in form  satisfactory  to
Lender,  and certified as true and correct by a  Responsible  Officer (or by any
other  officers or employees of Borrower or MXL whom a Responsible  Officer from
time to time  authorizes in writing to do so), and delivered to Lender from time
to  time  solely  for  Lender's   convenience  in  maintaining  records  of  the
Collateral.  The  failure of  Borrower  or MXL to  deliver  any of such items to
Lender shall not affect,  terminate,  modify,  or  otherwise  limit the Liens of
Lender on the Collateral.

            2.1.5 Revolving Credit Note.

            The obligation of Borrower to pay the Revolving Loan, with interest,
shall be evidenced by a promissory note (as from time to time extended, amended,
restated,  supplemented  or otherwise  modified,  the  "Revolving  Credit Note")
substantially  in the form of EXHIBIT B attached  hereto and made a part hereof,
with appropriate insertions.  The Revolving Credit Note shall be dated as of the
Closing Date,  shall be payable to the order of Lender at the times  provided in
the Revolving Credit Note, and shall be in the principal amount of the Revolving
Credit  Committed  Amount.   Borrower  acknowledges  and  agrees  that,  if  the
outstanding  principal  balance of the Revolving Loan  outstanding  from time to



time exceeds the face amount of the Revolving Credit Note, the excess shall bear
interest at the  Post-Default  Rate for the Revolving Loan and shall be payable,
with accrued interest, ON DEMAND. The Revolving Credit Note shall not operate as
a novation of any of the Obligations or nullify,  discharge, or release any such
Obligations or the continuing contractual  relationship of the parties hereto in
accordance with the provisions of this Agreement.

            2.1.6 Mandatory Prepayments of Revolving Loan.

            Borrower  shall make the  mandatory  prepayments  (each a "Revolving
Loan Mandatory  Prepayment"  and  collectively,  the  "Revolving  Loan Mandatory
Prepayments")  of the  Revolving  Loan at any time and from time to time in such
amounts as is required  pursuant to Section 2.1.3  (Borrowing  Base) in order to
cover any Borrowing Base Deficiency.

            2.1.7 Optional Prepayments of Revolving Loan.

            Borrower  shall have the option,  at any time and from time to time,
to prepay (each a "Revolving  Loan Optional  Prepayment"  and  collectively  the
"Revolving Loan Optional  Prepayments")  the Revolving Loan, in whole or in part
without premium or penalty.

            2.1.8 The Collateral Account.

            Borrower  will  deposit,  or cause  to be  deposited,  all  Items of
Payment to a bank account or bank  accounts  designated by Lender and from which
Lender alone has power of access and withdrawal  (collectively,  the "Collateral
Account").  In the case of any deposit that is made by Borrower  manually (i.e.,
the payment is  received by the  Borrower  rather  than being  delivered  to the
Lockbox or wired to the  Collateral  Account),  such  deposit  shall be made not
later  than the next  Business  Day  after the date of  receipt  of the Items of
Payment. The Items of Payment shall be deposited in precisely the form received,
except for the endorsements of Borrower where necessary to permit the collection
of any such Items of Payment, Borrower hereby agreeing to make such endorsement.
In the event  Borrower  shall  fail to do so,  Lender is  hereby  authorized  by
Borrower  to make  the  endorsement  in the  name of  Borrower.  Prior to such a
deposit,  Borrower will not commingle any Items of Payment with any of the other
funds or property of  Borrower,  but will hold them  separate and apart in trust
and for the account of Lender.


            Borrower shall direct its Account  Debtors that all Items of Payment
are to be either  (a) wired to the  Collateral  Account  or (b) mailed to one or
more  post-office  boxes  designated by Lender,  or to such other  additional or
replacement  post-office  boxes  pursuant  to the request of Lender from time to
time (collectively, the "Lockbox"). Lender shall have unrestricted and exclusive
access to the Lockbox.


            Borrower hereby  authorizes  Lender to inspect all Items of Payment,
endorse all Items of Payment in the name of Borrower,  and deposit such Items of
Payment in the Collateral Account.  Lender reserves the right,  exercised in its
sole and absolute  discretion  from time to time,  to provide to the  Collateral
Account  credit prior to final  collection of an Item of Payment and to disallow
credit for any Item of Payment which is  unsatisfactory  to Lender. In the event
Items of Payment are returned to Lender for any reason  whatsoever,  Lender may,
in the  exercise  of its  discretion  from time to time,  forward  such Items of
Payment a second time.  Any returned  Items of Payment  shall be charged back to
the  Collateral  Account,  the Revolving  Loan  Account,  or other  account,  as
appropriate.



            Lender  will  apply  the  whole or any part of the  collected  funds
credited to the Collateral  Account  (including  funds received from the Blocked
Account)  against the  Revolving  Loan (or with respect to Items of Payment that
are not proceeds of Accounts or after the occurrence and during the  continuance
of an Event of Default, against any of the Obligations) or credit such collected
funds to a  depository  account of  Borrower  with  Lender (or an  Affiliate  of
Lender),  the order and method of such  application to be in the sole discretion
of Lender.

            2.1.9 Revolving Loan Account.

            Lender will  establish and maintain a loan account on its books (the
"Revolving  Loan  Account")  to which  Lender  will (a) debit (i) the  principal
amount of each advance of the Revolving Loan made by Lender  hereunder as of the
date made, (ii) the amount of any interest  accrued on the Revolving Loan as and
when due, and (iii) any other amounts due and payable by Borrower to Lender from
time to time under the  provisions  of this  Agreement  in  connection  with the
Revolving Loan,  including,  without  limitation,  Enforcement Costs, Fees, late
charges,  and service,  collection  and audit fees, as and when due and payable,
and (b)  credit  all  payments  made by  Borrower  to Lender on  account  of the
Revolving Loan as of the date made including, without limitation, funds credited
to the Revolving Loan Account from the Collateral Account.  Lender may debit the
Revolving Loan Account for the amount of any Item of Payment that is returned to
Lender unpaid.  All credit entries to the Revolving Loan Account are conditional
and shall be readjusted as of the date made if final and indefeasible payment is
not received by Lender in cash or solvent credits. Any and all periodic or other
statements or reconciliations, and the information contained in those statements
or  reconciliations,  of the Revolving Loan Account shall be final,  binding and
conclusive upon Borrower in all respects,  absent manifest error,  unless Lender
receives  specific  written  objection  thereto from Borrower within thirty (30)
Business  Days after such  statement or  reconciliation  shall have been sent by
Lender.

            2.1.10 Revolving Credit Unused Line Fee.

            Borrower  shall  pay to  Lender  a  revolving  credit  facility  fee
(collectively,  the  "Revolving  Credit  Unused Line Fees" and  individually,  a
"Revolving Credit Unused Line Fee") in an amount equal to three-eighths  percent
(3/8%) per annum of the  average  daily  unused and  undisbursed  portion of the
Revolving  Credit  Committed  Amount in effect from time to time accruing during
each quarter. The accrued and unpaid portion of the Revolving Credit Unused Line
Fee  shall be paid in  arrears  by  Borrower  to Lender on the first day of each
September, December, March and June, commencing on the first such date following
the date hereof, and on the Revolving Credit Termination Date.

Section 2.2 The Letter of Credit Facility.

            2.2.1 Letters of Credit.

            Subject to and upon the provisions of this Agreement,  and as a part
of the Revolving Credit Commitment, Borrower, upon the prior approval of Lender,
may  obtain  standby  letters  of  credit  (as the same may from time to time be
amended,  supplemented  or  otherwise  modified,  each a "Letter of Credit"  and
collectively  the  "Letters of  Credit")  from Lender from time to time from the
Closing Date until the Business Day preceding the Revolving  Credit  Termination



Date.  Borrower  will not be  entitled  to obtain a Letter  of Credit  hereunder
unless (a) after giving effect to the request, the outstanding principal balance
of the Revolving Loan and of the Letter of Credit  Obligations  would not exceed
the lesser of (i) the Revolving Credit Committed Amount or (ii) the most current
Borrowing  Base  and  (b) the  sum of the  aggregate  face  amount  of the  then
outstanding Letters of Credit (including the face amount of the requested Letter
of Credit) does not exceed One Million Dollars ($1,000,000)

            2.2.2 Letter of Credit Fees.

            Prior  to or  simultaneously  with the  opening  of each  Letter  of
Credit,  Borrower shall pay to Lender, a letter of credit fee (each a "Letter of
Credit Fee" and  collectively the "Letter of Credit Fees") in an amount equal to
the customary fee charged commercial  customers for a Letter of Credit from time
to time. The Letter of Credit Fees shall be paid upon the opening of each Letter
of Credit and upon each anniversary thereof, if any. In addition, Borrower shall
pay to  Lender  all  other  reasonable  and  customary  amendment,  negotiation,
processing, transfer or other fees to the extent and as and when required by the
provisions of any Letter of Credit Agreement.  All Letter of Credit Fees and all
such other  additional fees are included in and are a part of the "Fees" payable
by  Borrower  under  the  provisions  of  this  Agreement  and are a part of the
Obligations.

            2.2.3 Terms of Letters of Credit.

            Each  Letter of Credit  shall (a) be opened  pursuant to a Letter of
Credit  Agreement,  and (b)  expire on a date not later  than the  Business  Day
preceding the Revolving Credit Expiration Date; provided, however, if any Letter
of Credit does have an expiration date later than the Business Day preceding the
Revolving  Credit  Termination  Date  (each a  "Post-Expiration  Date  Letter of
Credit"  and  collectively,  the  "Post-Expiration  Date  Letters  of  Credit"),
effective as of the Business Day preceding the Revolving Credit Termination Date
and  without  prior  notice to or the  consent of  Borrower,  Lender  shall make
advances  under the Revolving  Loan for the account of Borrower in the aggregate
face amount of all such Letters of Credit.  Lender shall deposit the proceeds of
such advances  into one or more  non-interest  bearing  accounts with and in the
name of Lender and over which Lender alone shall have exclusive  power of access
and withdrawal  (collectively,  the "Letter of Credit Cash Collateral Account").
The  Letter  of  Credit  Cash  Collateral  Account  is to be held by  Lender  as
additional collateral and security for any Letter of Credit Obligations relating
to the Post-Expiration Date Letters of Credit. Borrower hereby assigns, pledges,
grants and sets over to Lender a first priority  security  interest in, and Lien
on, all of the funds on deposit in the Letter of Credit Cash Collateral Account,
together with any and all proceeds and products thereof as additional collateral
and   security   for  the  Letter  of  Credit   Obligations   relating   to  the
Post-Expiration  Date Letters of Credit.  Borrower  acknowledges and agrees that
Lender shall be entitled to fund any draw or draft on any  Post-Expiration  Date
Letter of  Credit  from the  monies  on  deposit  in the  Letter of Credit  Cash
Collateral Account with notice to but without the consent of Borrower.  Borrower
further acknowledges and agrees that Lender's election to fund any draw or draft
on any  Post-Expiration  Date  Letter of Credit  from the Letter of Credit  Cash
Collateral shall in no way limit, impair,  lessen,  reduce, release or otherwise
adversely affect Borrower's  obligation to pay any Letter of Credit  Obligations
under or relating to the Post-Expiration Date Letters of Credit. At such time as
all  Post-Expiration  Date Letters of Credit have expired,  all Obligations have
been paid in full, and the Commitment has been  terminated,  any remaining funds
on deposit  in the Letter of Credit  Cash  Collateral  Account  shall be paid to
Borrower.



            The  aggregate  face amount of all Letters of Credit at any one time
outstanding  and issued by Lender  pursuant to the provisions of this Agreement,
including,  without  limitation,  any and all  Post-Expiration  Date  Letters of
Credit, plus the amount of any unpaid Letter of Credit Fees accrued thereon, and
less the aggregate  amount of all drafts issued under or purporting to have been
issued  under such Letters of Credit that have been paid by Lender and for which
Lender has been  reimbursed by Borrower in full in accordance with Section 2.2.5
(Payments  of Letters of Credit)  and the Letter of Credit  Agreements,  and for
which  Lender has no further  obligation  or  commitment  to restore  all or any
portion of the amounts drawn and reimbursed,  is herein called the  "Outstanding
Letter of Credit Obligations".

            2.2.4 Procedures for Letters of Credit.

            Borrower shall give Lender written notice at least five (5) Business
Days  prior to the date on which  Borrower  desires  Lender to issue a Letter of
Credit.  Such notice shall be  accompanied  by a duly executed  Letter of Credit
Agreement  specifying,  among  other  things:  (a) the name and  address  of the
intended  beneficiary of the Letter of Credit,  (b) the requested face amount of
the Letter of Credit,  (c)  whether the Letter of Credit is to be  revocable  or
irrevocable,  (d) the Business Day on which the Letter of Credit is to be opened
and the date on which  the  Letter  of  Credit  is to  expire,  (e) the terms of
payment  of any draft or drafts  which may be drawn  under the Letter of Credit,
and (f) any other terms or  provisions  Borrower  desires to be contained in the
Letter  of  Credit.  Such  notice  shall  also  be  accompanied  by  such  other
information, certificates,  confirmations, and other items as Lender may require
to assure that the Letter of Credit is issued in accordance  with the provisions
of this Agreement and a Letter of Credit Agreement. In the event of any conflict
between the  provisions  of this  Agreement  and the  provisions  of a Letter of
Credit  Agreement,  the provisions of this  Agreement  shall prevail and control
unless otherwise expressly provided in the Letter of Credit Agreement.  Upon (x)
receipt of such  notice,  (y) payment of all Letter of Credit Fees and all other
Fees payable in connection  with the issuance of such Letter of Credit,  and (z)
receipt of a duly executed Letter of Credit Agreement, Lender shall process such
notice  and  Letter  of  Credit  Agreement  in  accordance  with  its  customary
procedures  and open such Letter of Credit on the Business Day specified in such
notice.

            2.2.5 Payments of Letters of Credit.

            Borrower hereby  promises to pay to Lender,  ON DEMAND and in United
States Dollars,  the following which are herein collectively  referred to as the
"Current Letter of Credit Obligations":

                 (a) the amount which Lender has paid or will be required to pay
        under each draft or draw on a Letter of Credit,  whether  such demand be
        in advance of Lender's payment or for reimbursement for such payment;

                 (b) any and all  reasonable  charges and expenses  which Lender
        may pay or incur  relative to the Letter of Credit  and/or such draws or
        drafts; and

                 (c)  interest on the amounts  described in (a) and (b) not paid
        by Borrower as and when due and payable under the  provisions of (a) and
        (b) above from the day the same are due and  payable  until paid in full
        at the Post-Default Rate.



            In  addition,  Borrower  hereby  promises  to pay any and all  other
Letter of Credit  Obligations as and when due and payable in accordance with the
provisions of this Agreement and the Letter of Credit Agreements. The obligation
of Borrower to pay Current Letter of Credit  Obligations and all other Letter of
Credit  Obligations  shall  be  absolute  and  unconditional  under  any and all
circumstances and irrespective of any setoff, counterclaim or defense to payment
which  Borrower  or any other  account  party may have or have had  against  the
beneficiary of such Letter of Credit,  Lender,  or any other Person,  including,
without  limitation,  any  defense  based on the failure of any draft or draw to
conform  to the terms of such  Letter  of  Credit,  any draft or other  document
proving  to be  forged,  fraudulent  or  invalid,  or  the  legality,  validity,
regularity  or  enforceability  of such  Letter  of  Credit,  any draft or other
documents  presented  with any  draft,  any  Letter  of Credit  Agreement,  this
Agreement,  or any of the other Financing  Documents,  all whether or not Lender
had  actual or  constructive  knowledge  of the same,  and  irrespective  of any
Collateral,  security or  guarantee  therefor  or right of offset  with  respect
thereto  and   irrespective  of  any  other   circumstances   whatsoever   which
constitutes,  or  might  be  construed  to  constitute,  an  equitable  or legal
discharge of Borrower for any Letter of Credit  Obligations,  in  bankruptcy  or
otherwise;  provided, however, that Borrower shall not be obligated to reimburse
Lender for any wrongful  payment under such Letter of Credit made as a result of
Lender's gross negligence or willful  misconduct.  The obligation of Borrower to
pay the Letter of Credit Obligations shall not be conditioned or contingent upon
the  pursuit  by Lender  or any other  Person at any time of any right or remedy
against any Person  which may be or become  liable in respect of all or any part
of such obligation or against any Collateral,  security or guarantee therefor or
right of offset with respect thereto.


            The Letter of Credit Obligations shall continue to be effective,  or
be reinstated,  as the case may be, if at any time payment of all or any portion
of the Letter of Credit  Obligations  is rescinded or must otherwise be restored
or returned by Lender upon the insolvency, bankruptcy, dissolution,  liquidation
or  reorganization of any Person, or upon or as a result of the appointment of a
receiver,  intervenor, or conservator of, or trustee or similar officer for, any
Person,  or any substantial part of such Person's  property,  all as though such
payments had not been made.

            2.2.6 Change in Law; Increased Cost.

            If any  change  in any law or  regulation  or in the  interpretation
thereof  by  any  court  or  other  Governmental   Authority  charged  with  the
administration  thereof  occurring after the date of this Agreement shall either
(a) impose,  modify or deem  applicable any reserve,  special deposit or similar
requirement  against Letters of Credit issued by Lender, or (b) impose on Lender
any other  condition  regarding this Agreement or any Letter of Credit,  and the
result of any event referred to in clauses (a) or (b) above shall be to increase
the cost to Lender of issuing,  maintaining or extending the Letter of Credit or
the cost to Lender of funding any  obligation  under or in  connection  with the



Letter of Credit (other than a cost relating to net income, franchise or similar
taxes),  then, upon demand by Lender,  Borrower shall  immediately pay to Lender
from time to time as  specified  by Lender,  additional  amounts  which shall be
sufficient to compensate Lender for such increased cost,  together with interest
on each such amount from the date  demanded  until  payment in full thereof at a
rate per  annum  equal to the  then  highest  current  rate of  interest  on the
Revolving  Loan. A  certificate  as to such  increased  cost incurred by Lender,
submitted by Lender to Borrower, shall be conclusive, absent manifest error.

            2.2.7 General Letter of Credit Provisions.

            Borrower  consents to Lender's  payment of any draft  complying with
the terms of any Letter of Credit  irrespective of any  instructions of Borrower
to the contrary.  As between Borrower and Lender,  Borrower assumes all risks of
the acts and  omissions  of the  beneficiary  and other  users of any  Letter of
Credit.  Lender and its respective  branches,  Affiliates and/or  correspondents
shall not be responsible  for and Borrower  hereby  indemnifies and holds Lender
and its respective branches,  Affiliates and/or correspondents harmless from and
against all liability,  loss and expense (including  reasonable  attorney's fees
and  costs)   incurred  by  Lender  and/or  its  branches,   Affiliates   and/or
correspondents  relative  to  and/or  as a  consequence  of (a) any  failure  by
Borrower  to perform  the  agreements  hereunder  and under any Letter of Credit
Agreement,  (b) any Letter of Credit  Agreement,  this Agreement,  any Letter of
Credit and any draft,  draw and/or acceptance under or purported to be under any
Letter of Credit,  (c) any action  taken or omitted by Lender  and/or any of its
respective  branches,   Affiliates  and/or  correspondents  at  the  request  of
Borrower,  (d) any failure or inability to perform in accordance  with the terms
of any Letter of Credit by reason of any control or  restriction  rightfully  or
wrongfully exercised by any de facto or de jure Governmental Authority, group or
individual asserting or exercising  governmental or paramount powers, and/or (e)
any consequences  arising from causes beyond the control of Lender and/or any of
its respective branches, Affiliates and/or correspondents.


            Except for gross  negligence or willful  misconduct,  Lender and its
respective branches,  Affiliates and/or  correspondents,  shall not be liable or
responsible in any respect for any (a) error, omission, interruption or delay in
transmission,  dispatch or  delivery  of any one or more  messages or advices in
connection with any Letter of Credit,  whether transmitted by cable,  telegraph,
mail or otherwise  and despite any cipher or code which may be employed,  and/or
(b) action, inaction or omission which may be taken or suffered by it or them in
good faith or through  inadvertence  in  identifying  or failing to identify any
beneficiary or otherwise in connection with any Letter of Credit.


            Subject to the terms of the Letter of Credit, a Letter of Credit may
be amended,  modified or revoked  only upon the receipt by Lender from  Borrower
and the  beneficiary  (including any transferee  and/or assignee of the original
beneficiary), of a written consent and request therefor.


            If any  Laws,  order of court  and/or  ruling or  regulation  of any
Governmental  Authority of the United States (or any state  thereof)  and/or any
country  other than the United States  permits a  beneficiary  under a Letter of
Credit to require  Lender  and/or  any of its  respective  branches,  Affiliates
and/or  correspondents to pay drafts under or purporting to be under a Letter of
Credit  after the  expiration  date of the  Letter  of  Credit,  Borrower  shall
reimburse Lender, as appropriate, for any such payment pursuant to provisions of
Section 2.2.6 (Change in Law; Increased Cost).



            Except as may  otherwise  be  specifically  provided  in a Letter of
Credit  or Letter of  Credit  Agreement,  the laws of the State and the  Uniform
Customs and Practice  for  Documentary  Credits,  1993  Revision,  International
Chamber of Commerce  Publication No. 500 shall govern the Letters of Credit. The
Laws, rules,  provisions and regulations of the Uniform Customs and Practice for
Documentary  Credits are hereby  incorporated  by  reference.  In the event of a
conflict  between the Uniform Customs and Practice for  Documentary  Credits and
the laws of the State, the Uniform Customs and Practice for Documentary  Credits
shall prevail.

Section 2.3   Applicable Interest Rates.

              (a) Each advance of the Revolving  Loan shall bear interest  until
        maturity (whether by acceleration,  declaration, extension or otherwise)
        at the Applicable  Rate as determined in accordance  with the provisions
        of this Section.

              (b)  Notwithstanding  the foregoing,  following the occurrence and
        during the continuance of an Event of Default,  at the option of Lender,
        all advances of the Revolving Loan and all other  Obligations shall bear
        interest at the Post-Default Rate.

              (c) The  Applicable  Margin  shall be 300 basis  points  per annum
        unless  and until a change  is  required  by the  operation  of  Section
        2.3(d).

              (d)  Changes  in the  Applicable  Margin  shall  be made  not more
        frequently  than  quarterly  based on the Pricing  Ratio,  determined by
        Lender  subsequent  to its review of the quarterly  reports  required by
        Section 7.1.1(c)  (Quarterly  Statements and Certificates),  except that
        the first such  determination  shall be made based on Borrower's  annual
        financial statements required by Section 7.1.1(a) (Annual Statements and
        Certificates)  for  Borrower's  fiscal year ended  December 31, 2003 and
        shall be  effective  as of the first day of the first month after Lender
        receives and reviews such statements.  The Applicable  Margin (expressed
        as basis  points)  shall  vary  depending  upon the  Pricing  Ratio,  as
        follows:



                                    Pricing Ratio                                           Applicable Margin
             (both covenants achieved for two (2) consecutive quarters)

Total Liabilities to Net Worth                Interest Coverage Ratio
                                                                              
Equal to or less than 2.0 to 1.0              Greater than 2.5 to 1.0                        275 basis points
Equal to or less than 1.5 to 1.0              Greater than 2.5 to 1.0                        250 basis points



Section 2.4 General Financing Provisions.

            2.4.1 Borrowers' Representatives.

            Lender is hereby irrevocably authorized by Borrower to make advances
under  the  Revolving  Loan  to  Borrower  pursuant  to the  provisions  of this
Agreement upon the written,  oral or telephone request of any one or more of the
Persons who is from time to time a  Responsible  Officer of  Borrower  under the
provisions  of the most  recent  certificate  of  corporate  resolutions  and/or
incumbency of Borrower on file with Lender.

            Lender  assumes  no  responsibility  or  liability  for any  errors,
mistakes,  and/or  discrepancies  in the  oral,  telephonic,  written  or  other



transmissions of any instructions,  orders, requests and confirmations delivered
by Borrower to Lender in connection with the Credit  Facilities,  any advance of
the Revolving Loan, any Letter of Credit or any other  transaction in connection
with the provisions of this Agreement.

            2.4.2 Use of Proceeds of the Revolving Loan.

            The proceeds of each advance under the Revolving  Loan shall be used
by  Borrower  for  Permitted  Uses,  and for no  other  purposes  except  as may
otherwise be agreed by Lender in writing.

            2.4.3 Origination Fee.

            Borrower  shall pay to Lender on or before the  Closing  Date a loan
origination  fee (the  "Origination  Fee") in the  amount of Two  Hundred  Fifty
Thousand   Dollars   ($250,000),   which  fee  has  been  fully  earned  and  is
non-refundable.  Prior to the date  hereof  Borrower  has paid a portion  of the
Origination Fee in the amount of Seventy Five Thousand  Dollars  ($75,000);  the
balance due as of the date hereof is One Hundred  Seventy Five Thousand  Dollars
($175,000).

            2.4.4 Monitoring Fee.

            Borrower shall pay to Lender a monthly  monitoring fee in the amount
of $700  (collectively,  the "Monitoring Fees" and  individually,  a "Monitoring
Fee") commencing on the first such date following the date hereof and continuing
until the Revolving Credit Termination Date. Borrower authorizes Lender to debit
demand deposit  account number  _____________________  or any other account with
Lender (routing number 056-007604) designated in writing by Borrower,  beginning
as of the date hereof for any Monitoring Fee.  Borrower  further  certifies that
Borrower  holds  legitimate  ownership  of this account and  preauthorizes  this
periodic debit as part of its right under said ownership.

            2.4.5 Computation of Interest and Fees.

            All applicable Fees and interest shall be calculated on the basis of
a year of 360 days for the actual number of days elapsed.

            2.4.6 Maximum Interest Rate.

            In no event shall any interest rate  provided for  hereunder  exceed
the maximum rate  permissible for corporate  borrowers under  applicable law for
loans of the type provided for hereunder (the "Maximum Rate"). If, in any month,
any interest rate, absent such limitation, would have exceeded the Maximum Rate,
then the  interest  rate for that month  shall be the Maximum  Rate,  and, if in
future months, that interest rate would otherwise be less than the Maximum Rate,
then that  interest rate shall remain at the Maximum Rate until such time as the
amount of interest paid hereunder equals the amount of interest which would have
been paid if the same had not been  limited by the  Maximum  Rate.  In the event
that, upon payment in full of the Obligations, the total amount of interest paid
or accrued  under the terms of this  Agreement  is less than the total amount of
interest  which would,  but for this  Section,  have been paid or accrued if the
interest  rates  otherwise set forth in this  Agreement had at all times been in



effect,  then Borrower  shall,  to the extent  permitted by applicable  law, pay
Lender,  an amount  equal to the  excess of (a) the  lesser of (i) the amount of
interest  which would have been  charged if the Maximum  Rate had, at all times,
been in effect or (ii) the amount of interest  which would have  accrued had the
interest  rates  otherwise set forth in this  Agreement,  at all times,  been in
effect  over (b) the amount of  interest  actually  paid or  accrued  under this
Agreement.  In the  event  that a court  determines  that  Lender  has  received
interest and other charges  hereunder in excess of the Maximum Rate, such excess
shall be deemed  received on account of, and shall  automatically  be applied to
reduce,  the Obligations other than interest,  in the inverse order of maturity,
and if there are no  Obligations  outstanding,  Lender  shall refund to Borrower
such excess.

            2.4.7 Payments.

            All  payments of the  Obligations,  including,  without  limitation,
principal,  interest,  Prepayments,  and Fees, shall be paid by Borrower without
setoff,  recoupment or counterclaim to Lender in immediately available funds not
later  than  2:00  p.m.  (Eastern  Time)  on the due date of such  payment.  All
payments  received  by  Lender  after  such  time  shall be  deemed to have been
received by Lender for purposes of computing  interest and Fees and otherwise as
of the next Business Day.  Payments  shall not be considered  received by Lender
until  such  payments  are paid to  Lender  in  immediately  available  funds to
Lender's  principal  office in Baltimore,  Maryland or at such other location as
Lender may at any time and from time to time notify Borrower.  Alternatively, at
its sole discretion, Lender may charge any deposit account of Borrower at Lender
or any  Affiliate  of Lender  with all or any part of any  amount  due to Lender
under this Agreement or any of the other Financing  Documents to the extent that
Borrower shall have not otherwise tendered payment to Lender.

            2.4.8 Liens; Setoff.

            Borrower  hereby  grants  to  Lender as  additional  collateral  and
security for all of the  Obligations,  a continuing  Lien on any and all monies,
Investment  Property,  and other  property of Borrower  and any and all proceeds
thereof,  now or hereafter held or received by or in transit to, Lender,  and/or
any Affiliate of Lender, from or for the account of, Borrower, and also upon any
and all deposit accounts  (general or special) and credits of Borrower,  if any,
with Lender or any  Affiliate of Lender,  at any time  existing,  excluding  any
deposit accounts held by Borrower in its capacity as trustee for Persons who are
not Affiliates of Borrower.  Without implying any limitation on any other rights
Lender may have under the  Financing  Documents or applicable  Laws,  during the
continuance of an Event of Default,  Lender is hereby  authorized by Borrower at
any time and from time to time,  without notice to, or consent of, Borrower,  to
set off,  appropriate,  seize,  freeze  and apply  any or all items  hereinabove
referred to against all Obligations then outstanding  (whether or not then due),
all in such  order and manner as shall be  determined  by Lender in its sole and
absolute discretion.

            2.4.9 Requirements of Law.

            In the event that Lender  shall have  determined  in good faith that
(a) the adoption of any Capital  Adequacy  Regulation,  or (b) any change in any
Capital Adequacy  Regulation or in the interpretation or application  thereof or
(c) compliance by Lender or any corporation  controlling Lender with any request
or directive regarding capital adequacy (whether or not having the force of law)
from any central bank or Governmental  Authority,  does or shall have the effect
of  reducing  the rate of return  on the  capital  of Lender or any  corporation
controlling Lender, as a consequence of the obligations of Lender hereunder to a



level below that which Lender or any corporation  controlling  Lender would have
achieved but for such adoption,  change or compliance (taking into consideration
the policies of Lender and the corporation  controlling  Lender, with respect to
capital  adequacy)  by an amount  deemed by  Lender,  in its  discretion,  to be
material,  then from time to time,  after  submission by Lender to Borrower of a
written   request   therefor   and  a  statement   of  the  basis  for  Lender's
determination,  Borrower shall pay to Lender ON DEMAND such additional amount or
amounts in order to compensate  Lender or its  controlling  corporation  for any
such reduction.

            2.4.10 ACH Transactions and Swap Contracts.

            Borrower may request and Lender or its Affiliates may, in their sole
and absolute  discretion,  provide ACH Transactions  and Swap Contracts.  In the
event Borrower  requests Lender or its Affiliates to procure ACH Transactions or
Swap  Contracts,  then  Borrower  agrees  to  indemnify  and hold  Lender or its
Affiliates  harmless  from any and all  obligations  now or  hereafter  owing to
Lender  or its  Affiliates  in  connection  with such ACH  Transactions  or Swap
Contracts  other  than  obligations  arising  as a  result  of  Lender's  or its
Affiliates'  gross  negligence  or willful  misconduct.  Borrower  agrees to pay
Lender or its Affiliates all amounts owing to Lender or its Affiliates  pursuant
to ACH  Transactions  and Swap  Contracts.  In the event Borrower shall not have
paid to Lender or its Affiliates such amounts,  Lender may cover such amounts by
an advance under the Revolving Loan,  which advance shall be deemed to have been
requested by Borrower.  Borrower  acknowledges  and agrees that the obtaining of
ACH  Transactions and Swap Contracts from Lender or its Affiliates (a) is in the
sole and absolute  discretion of Lender or its  Affiliates and (b) is subject to
all rules and regulations of Lender or its Affiliates.

            2.4.11 Termination of Revolving Credit Facility.

            Borrower  shall have the right to terminate or reduce the  Revolving
Credit Commitment,  in whole or in part, upon at least thirty (30) Business Days
prior  written  notice to Lender,  without  any  premium or  penalty;  provided,
however,  that all Outstanding  Letter of Credit Obligations shall be secured as
provided in Section 2.2.3 (Terms of Letters of Credit).

            2.4.12 Elimination of MXL Receivables from Borrowing Base.

            Notwithstanding  anything  else  herein  or in any of the  Financing
Documents, at Borrower's option and upon written notice from Borrower to Lender,
the Borrowing  Base shall be revised to eliminate  MXL's  Eligible  Receivables;
provided,  however, Borrower shall make a Revolving Loan Mandatory Prepayment as
required pursuant to Section 2.1.6 (Mandatory  Prepayments) so that no Borrowing
Base  Deficiency  exists  as of the  date of  elimination  of the  MXL  Eligible
Receivables  from the Borrowing  Base. Upon such election and notice by Borrower
and payment of any Borrowing Base  Deficiency (a) all obligations of MXL related
to the Borrowing Base and Eligible Receivables shall immediately terminate,  (b)
this Agreement  shall be deemed  modified to eliminate all references to MXL and
any  and  all  obligations  of MXL  under  this  Agreement  or any of the  other
Financing Documents shall cease; (c) cease to require any financial reporting by
MXL or NPDC as provided in any of the Financing  Documents,  and (d) at the sole
cost of Borrower,  Lender  shall (i) void the Guaranty  executed by MXL and (ii)
terminate any Security Documents executed by MXL at the sole cost and expense of
Borrower.

the parties to this Agreement that Lender shall have a first priority, perfected
Lien, in form and substance  satisfactory  to Lender and its counsel,  on all of
the Borrower Collateral,  whether now owned or hereafter acquired,  subject only
to the Permitted Liens, if any. In furtherance of the foregoing:

                 (a) On the Closing Date and without  implying any limitation on

shall have received, in form and substance  satisfactory to Lender, such Lien or
record  searches  with  respect  to  Borrower   and/or  any  other  Person,   as
appropriate,  and the property  covered by such Financing  Document showing that
the Lien of such Financing  Document will be a perfected  first priority Lien on

        opinions required; and

                 (e) all related costs, fees and expenses.

                 Upon  the  indefeasible  repayment  in  full  in  cash  of  the
Obligations  and  performance  of all  Obligations  under this Agreement and all
other  Financing  Documents,  and  the  termination  and/or  expiration  of  the
Commitment,  all  Letters  of  Credit  and  all  Outstanding  Letter  of  Credit
Obligations,  or, in the case of Outstanding Letter of Credit  Obligations,  the
cash  collateralization  thereof  pursuant to Section 2.2.3 (Terms of Letters of
Credit), upon Borrower's request and at Borrower's sole cost and expense, Lender

directly  conflict with any provision of this Agreement,  the provisions of this
Agreement govern.

                    REPRESENTATIONS AND WARRANTIES - Borrower

Section 4.1      Representations and Warranties.

                 4.1.1 Subsidiaries.

                 Borrower  has  the   Subsidiaries   listed  on  the  Collateral
Disclosure  List and no  others.  Each of the  Subsidiaries  is a  Wholly  Owned
Subsidiary  except as shown on the Collateral  Disclosure  List, which correctly
indicates the nature and amount of Borrower's ownership interests therein.

                 4.1.2 Existence.

                 Borrower (a) is a Registered Organization under the laws of the
jurisdiction  stated in the Preamble of this Agreement,  (b) is in good standing
under the laws of the  jurisdiction in which it is organized,  (c) has the power
to own its property and to carry on its business as now being conducted, and (d)
is duly qualified to do business and is in good standing in each jurisdiction in
which  the  character  of the  properties  owned by it  therein  or in which the

organized under the laws of only one (1) jurisdiction.

                 4.1.3 Power and Authority.

                 Borrower  has full power and  authority  to execute and deliver
this Agreement and the other Financing Documents to which it is a party, to make
the borrowings  and request  Letters of Credit under this Agreement and to incur
and perform the Obligations  whether under this  Agreement,  the other Financing
Documents or otherwise, all of which have been duly authorized by all proper and
necessary action. No consent or approval of owners or any creditors of Borrower,
and  no  consent,  approval,  filing  or  registration  with  or  notice  to any
Governmental  Authority on the part of  Borrower,  is required as a condition to
the execution, delivery, validity or enforceability of this Agreement, or any of
the  other  Financing   Documents,   or  the  performance  by  Borrower  of  the
Obligations.

                 4.1.4 Binding Agreements.

                 This Agreement and the other Financing  Documents  executed and
delivered by Borrower have been properly  executed and delivered and  constitute
the valid and legally binding  obligations of Borrower and are fully enforceable
against  Borrower  in  accordance  with  their  respective  terms,   subject  to
bankruptcy,  insolvency,  reorganization,  moratorium  and other laws of general
application  affecting the rights and remedies of creditors and secured parties,
and general  principles of equity  regardless of whether applied in a proceeding
in equity or at law.




                 4.1.5 No Conflicts.

                 Neither the execution, delivery and performance of the terms of
this Agreement or of any of the other Financing Documents executed and delivered
by  Borrower  nor the  consummation  of the  transactions  contemplated  by this
Agreement  will  conflict  with,  violate  or be  prevented  by  (a)  Borrower's
organizational or governing  documents,  (b) any existing  mortgage,  indenture,
contract or agreement binding on Borrower or affecting its property,  except for
any conflict which could not have a materially  adverse  effect on Borrower,  or
(c) any applicable Laws.

                 4.1.6  No  Defaults,  Violations.  (a) No  Default  or Event of
Default has occurred and is continuing.

                 (b) Neither  Borrower nor any of its Subsidiaries is in default
under or with respect to any obligation under any existing mortgage,  indenture,
contract or  agreement  binding on it or  affecting  its property in any respect
which  could be  materially  adverse to the  business,  operations,  property or
financial condition of the Borrower,  or which could materially adversely affect
the ability of the Borrower to perform its  obligations  under this Agreement or
the other Financing Documents to which Borrower is a party.

                 4.1.7 Compliance with Laws.

                 Neither Borrower nor any of its Subsidiaries is in violation of
any  applicable  Laws  (including,  without  limitation,  any Laws  relating  to
employment  practices,  to environmental,  occupational and health standards and
controls) or order, writ, injunction, decree or demand of any court, arbitrator,
or any  Governmental  Authority  affecting  it or any  of  its  properties,  the
violation of which could materially adversely affect the business, operations or
properties of Borrower and its Subsidiaries taken as a whole.

                 4.1.8 Margin Stock.

                 None of the  proceeds  of the  Revolving  Loan  will  be  used,
directly  or  indirectly,  by  Borrower  or any  Subsidiary  for the  purpose of
purchasing  or  carrying,  or for  the  purpose  of  reducing  or  retiring  any
indebtedness  which was  originally  incurred to purchase or carry,  any "margin
stock"  within the meaning of  Regulation  U (12 CFR Part 221),  of the Board of
Governors of the Federal  Reserve  System or for any other  purpose  which might
make the  transactions  contemplated in this Agreement a "purpose credit" within
the  meaning of  Regulation  U, or cause  this  Agreement  to violate  any other
regulation  of the  Board of  Governors  of the  Federal  Reserve  System or the
Securities Exchange Act of 1934 or the Small Business Investment Act of 1958, as
amended, or any rules or regulations promulgated under any of such statutes.

                 4.1.9 Investment Company Act; Margin Stock.

                 Neither  Borrower nor any of its  Subsidiaries is an investment
company  within the meaning of the  Investment  Company Act of 1940, as amended,
nor is it,  directly  or  indirectly,  controlled  by or acting on behalf of any
Person which is an investment  company  within the meaning of said Act.  Neither
Borrower nor any of its  Subsidiaries is engaged  principally,  or as one of its



important  activities,  in the business of  extending  credit for the purpose of
purchasing or carrying "margin stock" within the meaning of Regulation U (12 CFR
Part 221), of the Board of Governors of the Federal Reserve System.

                 4.1.10 Litigation.

                 Except as  otherwise  disclosed  on  Schedule  4.1.10  attached
hereto and made a part  hereof,  there are no  proceedings,  actions  or, to the
knowledge  of  Borrower,  investigations  pending or, so far as Borrower  knows,
threatened  before or by any court,  arbitrator  or any  Governmental  Authority
which,  in any one case or in the  aggregate,  if  determined  adversely  to the
interests of Borrower or any Subsidiary, would have a material adverse effect on
the business,  properties,  condition  (financial or otherwise) or operations of
Borrower.

                 4.1.11 Financial Condition.

                 The  consolidated   financial   statements  of  Borrower  dated
December 31, 2002 and management prepared  consolidated  financial statements of
Borrower  dated June 30, 2003,  are complete and correct and fairly  present the
financial  position of Borrower  and its  Subsidiaries  and the results of their
operations and transactions in their surplus accounts as of the date and for the
period  referred to and have been prepared in accordance  with GAAP applied on a
consistent  basis  throughout  the  period  involved.   There  are  no  material
liabilities,  direct  or  indirect,  fixed or  contingent,  of  Borrower  or its
Subsidiaries as of the date of such financial  statements that are not reflected
therein  or in the  notes  thereto.  There  has been no  adverse  change  in the
financial condition or operations of Borrower or its Subsidiaries since the date
of such financial  statements and to Borrower's knowledge no such adverse change
is pending or  threatened.  Prior to the date hereof,  neither  Borrower nor any
Subsidiary  has  guaranteed  the  obligations  of, or made any  investment in or
advances to, any Person, except as disclosed in such financial statements or the
schedules hereto.

                 4.1.12 Full Disclosure.

                 The  financial   statements   referred  to  in  Section  4.1.11
(Financial Condition),  the Financing Documents (including,  without limitation,
this  Agreement),  and the  statements,  reports or  certificates  furnished  by
Borrower  in  connection  with the  Financing  Documents  (a) do not contain any
untrue statement of a material fact and (b) when taken in their entirety, do not
omit any material fact  necessary to make the statements  contained  therein not
misleading.  There is no fact known to Borrower which Borrower has not disclosed
to Lender in writing  prior to the date of this  Agreement  with  respect to the
transactions  contemplated  by  the  Financing  Documents  that  materially  and
adversely affects or in the future could, in the reasonable opinion of Borrower,
materially  adversely affect the condition,  financial or otherwise,  results of
operations,  business,  or assets of Borrower  and its  Subsidiaries  taken as a
whole.

                 4.1.13 Indebtedness for Borrowed Money.

                 Except for the  Obligations and except as set forth in Schedule
4.1.13 attached hereto and made a part hereof,  Borrower has no Indebtedness for
Borrowed  Money.  Lender  has  received  photocopies  of  all  promissory  notes
evidencing any  Indebtedness  for Borrowed  Money set forth in Schedule  4.1.13,



together with any and all subordination agreements, other agreements, documents,
or  instruments  securing,  evidencing,  guarantying  or otherwise  executed and
delivered in connection therewith.

                 4.1.14 Subordinated Debt.

                 None of the Subordinated  Debt Loan Documents has been amended,
supplemented,  restated or otherwise  modified except as otherwise  disclosed to
Lender  in  writing  on or  before  the  effective  date of any such  amendment,
supplement, restatement or other modification. In addition, there does not exist
any  default  or any event  which  upon  notice  or lapse of time or both  would
constitute  a  default  under  the  terms of any of the  Subordinated  Debt Loan
Documents.

                 4.1.15 Taxes.

                 Each of Borrower  and its  Subsidiaries  has filed all returns,
reports and forms for Taxes that, to the knowledge of Borrower,  are required to
be filed,  and has paid all Taxes as shown on such returns or on any  assessment
received by it, to the extent that such Taxes have become due, unless and to the
extent only that such Taxes,  assessments and governmental charges are currently
contested in good faith and by appropriate  proceedings by Borrower,  such Taxes
are not the  subject  of any Liens  other than  Permitted  Liens,  and  adequate
reserves  therefor  have  been  established  as  required  under  GAAP.  All tax
liabilities  of  Borrower  were as of the date of audited  financial  statements
referred to in Section 4.1.11  (Financial  Condition),  and are now,  adequately
provided for on the books of Borrower or its  Subsidiaries,  as appropriate.  No
tax liability has been asserted by the Internal  Revenue Service or any state or
local authority against Borrower for Taxes in excess of those already paid.

                 4.1.16 ERISA.

                 With  respect to any Plan,  and  except to the extent  that the
failure of any of the following  statements to be accurate would not result in a
material  liability to Borrower:  (a) no  "accumulated  funding  deficiency"  as
defined  in Code  ss.412  or ERISA  ss.302  has  occurred,  whether  or not that
accumulated  funding  deficiency  has been waived;  (b) no Reportable  Event has
occurred other than events for which reporting has been waived under  applicable
PBGC  regulations;  (c) no  termination of any plan subject to Title IV of ERISA
has  occurred;  (d) neither  Borrower  nor any  Commonly  Controlled  Entity has
incurred a "complete  withdrawal"  within the meaning of ERISA  ss.4203 from any
Multiemployer  Plan; (e) neither Borrower nor any Commonly Controlled Entity has
incurred a "partial withdrawal" within the meaning of ERISA ss.4205 with respect
to any  Multiemployer  Plan; (f) no Multiemployer  Plan to which Borrower or any
Commonly   Controlled   Entity   has  an   obligation   to   contribute   is  in
"reorganization"  within  the  meaning  of ERISA  ss.4241  nor has  notice  been

limited in any way to or by the  inclusion or exclusion  of  Receivables  within
such   assignments.   Receivables  so  assigned  shall  secure  payment  of  the

which is separate from this Agreement, is in form absolute. Borrower agrees that

affix any  Equipment to any real estate in such manner as to become a fixture or
part of such real estate,  and (c) shall hold no Equipment on a sale on approval
basis.  Borrower hereby declares its intent that,  notwithstanding  the means of
attachment,  no goods of  Borrower  hereafter  attached  to any realty  shall be
deemed a fixture,  which  declaration  shall be  irrevocable,  without  Lender's
consent,  until all of the Obligations have been paid in full and the Commitment
and all Letters of Credit have been terminated or have expired.

any of the other  Financing  Documents  and the  first  priority  of that  Lien,
subject only to the Permitted  Liens.  Borrower hereby  authorizes the filing of
any financing  statement or  continuation  statement  required under the Uniform
Commercial  Code.  Borrower  will  from  time  to time do  whatever  Lender  may
reasonably  require by way of obtaining,  executing,  delivering,  and/or filing
landlords'  waivers,  notices of assignment and other notices and amendments and
renewals  thereof  and  Borrower  will take any and all steps and  observe  such
formalities as Lender may require,  in order to create and maintain a valid Lien
upon,  pledge of, or paramount  security  interest in, the Borrower  Collateral,
subject  to the  Permitted  Liens.  Borrower  shall pay to Lender on demand  all
taxes, costs and expenses incurred by Lender in connection with the preparation,
execution,  recording  and filing of any such  document  or  instrument.  To the
extent that the proceeds of any of the Accounts or  Receivables  of Borrower are
expected to become  subject to the control of, or in the  possession of, a party
other than Borrower or Lender,  Borrower shall cause all such parties to execute
and  deliver on the  Closing  Date  security  documents  or other  documents  as
requested  by Lender and as may be  necessary  to  evidence  and/or  perfect the
security  interest  of Lender in those  proceeds.  Borrower  hereby  irrevocably

the name of  Lender or in the name of  Borrower  or  otherwise,  for the use and
benefit of Lender, but at the cost and expense of Borrower and without notice to
Borrower,  to  execute  and  deliver  any and all of the  instruments  and other

protect  the  interest of Lender in, and to preserve  the  Borrower  Collateral,
including,  the hiring of such security  guards or the placing of other security

from time to time  after  and  during  the  continuance  of an Event of  Default
hereunder,  revoke the  collection  privilege  given in this Agreement to MXL by
either giving notice of its assignment of, and lien on the MXL Collateral to the
Account  Debtors or giving notice of such  revocation  to MXL.  Lender shall not
have any duty to,  and MXL  hereby  releases  Lender  from all claims of loss or
damage  caused  by the  delay  or  failure  to  collect  or  enforce  any of the
Receivables  or to preserve any rights  against any other party with an interest
in the MXL  Collateral.  Lender  shall be  entitled at any time and from time to
time to confirm and verify Receivables.




               7.2.7 Assignments of Receivables.

               MXL will  promptly,  upon request,  execute and deliver to Lender
written  assignments,  in form and  content  acceptable  to Lender,  of specific
Receivables  or  groups  of  Receivables;  provided,  however,  the Lien  and/or
security interest granted to Lender under this Agreement shall not be limited in
any  way  to or by  the  inclusion  or  exclusion  of  Receivables  within  such
assignments. Receivables so assigned shall secure payment of the Obligations and
are not sold to Lender whether or not any assignment thereof,  which is separate
from this Agreement, is in form absolute. MXL agrees that neither any assignment
to Lender nor any other  provision  contained  in this  Agreement  or any of the
other Financing  Documents shall impose on Lender any obligation or liability of
MXL with  respect to that which is assigned  and MXL hereby  agrees to indemnify
Lender and hold Lender harmless from any and all claims, actions, suits, losses,
damages,  costs,  expenses,  fees,  obligations  and  liabilities  which  may be
incurred by or imposed  upon Lender by virtue of the  assignment  of and Lien on
MXL's rights, title and interest in, to, and under the MXL Collateral.

               7.2.8 Government Accounts.

               MXL will  immediately  notify  Lender  if any of the  Receivables
arise out of  Government  Contracts  for which,  pursuant to the  provisions  of
Section 3.2 (Grant of Liens),  MXL is  obligated to execute  documents  and take
steps  required  by Lender in order  that all moneys due and to become due under
such  contracts  shall be  assigned  to Lender and notice  thereof  given to the
Governmental Authority under the Federal Assignment of Claims Act.

               7.2.9 Notice of Returned Goods, etc.

               MXL will  promptly  notify  Lender of the  return,  rejection  or
repossession of any goods sold or delivered in respect of any  Receivables,  and
of any claims made in regard  thereto to the extent that the aggregate  purchase
price of any such goods in any given calendar month exceeds in the aggregate One
Hundred Thousand Dollars ($100,000.00) in any given calendar month.

               7.2.10 Defense of Title and Further Assurances.

               Subject to the terms of applicable  leases,  at its expense,  MXL
will defend the title to the MXL  Collateral  (and any part  thereof),  and will
immediately  execute,  acknowledge  and deliver any  renewal,  affidavit,  deed,
assignment,  security agreement,  certificate or other document which Lender may
require in order to perfect, preserve, maintain, continue, protect and/or extend
the Lien  granted  to  Lender  under  this  Agreement  or under any of the other
Financing  Documents  and the first  priority of that Lien,  subject only to the
Permitted Liens. MXL hereby authorizes the filing of any financing  statement or
continuation statement required under the Uniform Commercial Code. MXL will from
time to time do  whatever  Lender may  reasonably  require by way of  obtaining,
executing,  delivering,  and/or filing landlords' waivers, notices of assignment
and other notices and amendments and renewals  thereof and MXL will take any and
all steps and observe such formalities as Lender may require, in order to create



and maintain a valid Lien upon,  pledge of, or paramount  security  interest in,
the MXL Collateral,  subject to the Permitted  Liens. MXL shall pay to Lender on
demand all taxes,  costs and expenses  incurred by Lender in connection with the
preparation, execution, recording and filing of any such document or instrument.
To the extent that the proceeds of any of the Accounts or Receivables of MXL are
expected to become  subject to the control of, or in the  possession of, a party
other  than MXL or Lender,  MXL shall  cause all such  parties  to  execute  and
deliver on the Closing Date security  documents or other  documents as requested
by Lender and as may be  necessary  to  evidence  and/or  perfect  the  security
interest of Lender in those proceeds.  MXL hereby irrevocably appoints Lender as
MXL's attorney-in-fact,  with power of substitution, in the name of Lender or in
the name of MXL or otherwise, for the use and benefit of Lender, but at the cost
and expense of MXL and without notice to MXL, to execute and deliver any and all
of the  instruments  and other  documents  and take any action  which Lender may
require pursuant the foregoing provisions of this Section.

               7.2.11 Business Names; Locations.

               MXL will notify  Lender not less than  fifteen (15) days prior to
(a) any change in the name under which MXL conducts its business, (b) any change
of the location of the chief executive office of MXL, (c) the opening of any new
place of business or the closing of any existing place of business,  and (d) any
change in the location of the places  where the books and  records,  or any part
thereof, are kept.

               7.2.12 Protection of MXL Collateral.

               Subject to the terms of any  applicable  leases,  MXL agrees that
Lender may at any time following the occurrence and during the continuance of an
Event of Default take such steps as Lender deems reasonably necessary to protect
the interest of Lender in, and to preserve the MXL  Collateral,  including,  the
hiring of such  security  guards or the  placing  of other  security  protection
measures as Lender  deems  appropriate,  may employ and maintain at any of MXL's
premises a custodian who shall have full  authority to do all acts  necessary to
protect the interests of Lender in the MXL  Collateral  and may lease  warehouse
facilities to which Lender may move all or any part of the MXL Collateral to the
extent  commercially  reasonable.  MXL agrees to cooperate  fully with  Lender's
efforts  to  preserve  the MXL  Collateral  and,  subject  to the  terms  of any
applicable  leases,  will take such  actions to preserve the MXL  Collateral  as
Lender may  reasonably  direct.  All of Lender's  expenses of preserving the MXL
Collateral,  including any reasonable  expenses relating to the compensation and
bonding of a custodian, shall be part of the Enforcement Costs.

               Unless adequately  insured in the opinion of Lender, the entry of
a final judgment for the payment of money  involving more than $500,000  against

discharge the same, or cause it to be  discharged,  within thirty (30) days from
the date of the order,  decree or process  under which or pursuant to which such
judgment was entered,  or to secure a stay of execution  pending  appeal of such

Borrowed  Money (other than the Revolving  Loan) with an  outstanding  principal
amount of greater  than  $500,000 if the default is a failure to pay at maturity
or if the  effect  of  such  default  is to  accelerate  the  maturity  of  such
Indebtedness  for Borrowed  Money or to permit the holder or obligee  thereof or
other party thereto to cause such  Indebtedness for Borrowed Money to become due
prior to its stated maturity.

               8.1.11 Challenge to Agreements.

               Borrower  or any  Guarantor  shall  challenge  the  validity  and

any of the Collateral purported to be covered thereby.

               8.1.12 Material Adverse Change.

               Lender in its sole  discretion  determines  in good  faith that a
material  adverse change has occurred in the financial  condition of Borrower or
the value of the Collateral taken as a whole.

               8.1.13 Contract Default, Debarment or Suspension.

               Default shall be made under any Government  Contract with, or any

individual department, agency or instrumentality of the United States with which
the Borrower has  contracts in the  aggregate at that point in time with a value
in excess of  $10,000,000,  or if Borrower is  debarred  or  suspended,  whether
temporarily or permanently,  by the United States or any  department,  agency or
instrumentality of the United States.




               8.1.14 Liquidation, Termination, Dissolution, etc.

               Borrower shall liquidate,  dissolve or terminate its existence or

of Lender.

               Section 8.2 Remedies.

               Upon the  occurrence  and during the  continuance of any Event of
Default,  Lender may, in the exercise of its sole and absolute  discretion  from
time to  time,  exercise  any one or more of the  following  rights,  powers  or
remedies:

               8.2.1 Acceleration.

               Lender  may  declare  any  or  all  of  the   Obligations  to  be
immediately  due  and  payable,   notwithstanding  anything  contained  in  this
Agreement or in any of the other  Financing  Documents to the contrary,  without
presentment,  demand, protest, notice of protest or of dishonor, or other notice
of any kind, all of which Borrower hereby waives.

               8.2.2 Further Advances.

               Lender may from time to time without notice to Borrower  suspend,
terminate or limit any further  advances,  loans or other  extensions  of credit
under  the  Commitment,  under  this  Agreement  and/or  under  any of the other
Financing  Documents.  Further,  upon the  occurrence  of an Event of Default or
Default  specified in Section  8.1.6  (Receiver;  Bankruptcy)  or Section  8.1.7
(Involuntary  Bankruptcy,   etc.),  the  Revolving  Credit  Commitment  and  any
agreement in any of the Financing  Documents to provide additional credit and/or
to issue Letters of Credit shall immediately and automatically terminate and the
unpaid  principal  amount of the Notes (with accrued  interest  thereon) and all
other  Obligations then outstanding,  shall  immediately  become due and payable
without further action of any kind and without presentment,  demand,  protest or
notice of any kind, all of which are hereby expressly waived by Borrower.

               8.2.3 Uniform Commercial Code.

               Lender  shall have all of the rights  and  remedies  of a secured
party under the applicable  Uniform  Commercial Code and other  applicable Laws.
Upon  demand by Lender,  Borrower  shall  assemble  the  Collateral  and make it
available to Lender,  at a place  designated by Lender.  Subject to the terms of
any applicable leases, Lender or its agents may without notice from time to time
enter upon Borrower's or MXL's premises to take possession of the Collateral, to
remove it, to render it  unusable,  to process  it or  otherwise  prepare it for
sale, or to sell or otherwise dispose of it.


               Any written  notice of the sale,  disposition  or other  intended
action by Lender with respect to the  Collateral  which is sent by regular mail,
postage  prepaid,  to  Borrower  or MXL at the  address set forth in Section 9.1
(Notices),  or such other address of Borrower or MXL which may from time to time
be shown on  Lender's  records,  at least  ten  (10)  days  prior to such  sale,
disposition or other action, shall constitute  commercially reasonable notice to



Borrower of MXL, as applicable.  Lender may  alternatively or additionally  give
such  notice  in any  other  commercially  reasonable  manner.  Nothing  in this
Agreement  shall  require  Lender to give any notice not required by  applicable
Laws.


               If  any  consent,   approval,  or  authorization  of  any  state,
municipal  or other  Governmental  Authority  or of any  other  Person or of any
Person having any interest  therein,  should be necessary to effectuate any sale
or other  disposition of the  Collateral,  Borrower and MXL agree to execute all
such applications and other instruments, and to take all other action, as may be
required  in   connection   with   securing  any  such   consent,   approval  or
authorization.


               Borrower  and MXL each  recognizes  that  Lender may be unable to
effect a public sale of all or a part of the Collateral consisting of Investment
Property by reason of certain  prohibitions  contained in the  Securities Act of
1933,  as amended,  and other  applicable  Federal  and state Laws.  Lender may,
therefore,  in its  discretion,  take such steps as it may deem  appropriate  to
comply  with  such  Laws and may,  for  example,  at any sale of the  Collateral
consisting of securities  restrict the  prospective  bidders or purchasers as to
their number,  nature of business and investment intention,  including,  without
limitation,  a requirement that the Persons making such purchases  represent and
agree to the satisfaction of Lender that they are purchasing such securities for
their account, for investment, and not with a view to the distribution or resale
of any thereof. Borrower covenants and agrees to do or cause to be done promptly
all such acts and things as Lender may  request  from time to time and as may be
necessary  to offer and/or sell the  securities  or any part thereof in a manner
which is valid and binding and in conformance with all applicable Laws. Upon any
such sale or  disposition,  Lender  shall have the right to deliver,  assign and
transfer to the  purchaser  thereof the  Collateral  consisting of securities so
sold.

               8.2.4 Specific Rights With Regard to Collateral.

               In addition to all other rights and remedies  provided  hereunder
or as shall exist at law or in equity  from time to time,  Lender may (but shall
be under no obligation to),  without notice to Borrower or MXL, and Borrower and
MXL each hereby irrevocably appoints Lender as its attorney-in-fact,  with power
of  substitution,  in the name of Lender and/or in the name of Borrower,  MXL or
otherwise,  for the use and  benefit of Lender,  but at the cost and  expense of
Borrower and without notice to Borrower or MXL:

                    (a)  request  any  Account  Debtor  obligated  on any of the
     Accounts to make payments  thereon  directly to Lender,  with Lender taking
     control of the Proceeds thereof;

                    (b)  compromise,  extend or renew any of the  Collateral  or
     deal with the same as it may deem advisable;

                    (c) make  exchanges,  substitutions  or surrenders of all or
     any part of the Collateral;

                    (d) copy,  transcribe,  or remove from any place of business
     of Borrower,  MXL or any  Subsidiary  all books,  records,  ledger  sheets,
     correspondence,  invoices and  documents,  relating to or evidencing any of
     the  Collateral or without cost or expense to Lender,  subject to the terms
     of any  applicable  leases,  make  such  use of  Borrower's,  MXL's  or any



     Subsidiary's  place(s)  of  business  as may  be  reasonably  necessary  to
     administer, control and collect the Collateral;

                    (e) repair, alter or supply goods if necessary to fulfill in
     whole or in part the purchase order of any Account Debtor;

                    (f)  demand,   collect,   receipt  for  and  give  renewals,
     extensions, discharges and releases of any of the Collateral;

                    (g) institute and prosecute legal and equitable  proceedings
     to enforce collection of, or realize upon, any of the Collateral;

                    (h) settle, renew, extend, compromise, compound, exchange or
     adjust claims in respect of any of the Collateral or any legal  proceedings
     brought in respect thereof;

                    (i) endorse or sign the name of  Borrower  upon any Items of
     Payment,  certificates of title,  Instruments,  Investment Property,  stock
     powers, documents,  documents of title, financing statements,  assignments,
     notices,  or other writing relating to or part of the Collateral and on any
     proof of claim in bankruptcy against an Account Debtor;

                    (j) clear  Inventory  through  customs  in  Lender's  or, as
     applicable,  Borrower's  or MXL's  name and to sign and  deliver to customs
     officials powers of attorney in Borrower's or MXL's name for such purpose;

                    (k) notify the Post Office authorities to change the address
     for the  delivery of mail to Borrower to such address or Post Office Box as
     Lender may designate  and receive and open all mail  addressed to Borrower;
     and

                    (l) take any other action necessary or beneficial to realize
     upon or  dispose  of the  Collateral  or to  carry  out the  terms  of this
     Agreement.




               8.2.5 Application of Proceeds.

               Any proceeds of sale or other  disposition of the Collateral will
be applied by Lender to the payment first of any and all Enforcement  Costs, and
any balance of such  proceeds will be applied to the  Obligations  in such order
and manner as Lender shall  determine.  If the sale or other  disposition of the
Collateral fails to fully satisfy the Obligations,  Borrower shall remain liable
to Lender for any deficiency.

               8.2.6 Performance by Lender.

               Lender  without  notice to or demand  upon  Borrower  and without
waiving or releasing any of the  Obligations or any Default or Event of Default,
may (but  shall be under no  obligation  to) at any time  thereafter  make  such
payment or perform such act for the account and at the expense of Borrower,  and
may enter upon the  premises  of  Borrower  for that  purpose  and take all such



action thereon as Lender may consider necessary or appropriate for such purpose,
subject to the terms of any applicable  leases,  and Borrower hereby irrevocably
appoints Lender as its attorney-in-fact to do so, with power of substitution, in
the  name of  Lender,  in the name of  Borrower  or  otherwise,  for the use and
benefit of Lender, but at the cost and expense of Borrower and without notice to
Borrower.  All sums so paid or advanced by Lender together with interest thereon
from  the  date of  payment,  advance  or  incurring  until  paid in full at the
Post-Default  Rate and all  costs  and  expenses,  shall be  deemed  part of the
Enforcement  Costs,  shall be paid by  Borrower  to Lender on demand,  and shall
constitute and become a part of the Obligations.

               8.2.7 Other Remedies.

               Lender may from time to time  proceed  to protect or enforce  its
rights by an action or actions  at law or in equity or by any other  appropriate
proceeding,  whether  for  the  specific  performance  of any  of the  covenants
contained in this Agreement or in any of the other Financing  Documents,  or for
an injunction against the violation of any of the terms of this Agreement or any
of the other Financing Documents,  or in aid of the exercise or execution of any
right,  remedy or power  granted in this  Agreement,  the  Financing  Documents,
and/or  applicable Laws.  Lender is authorized to offset and apply to all or any
part of the  Obligations  all moneys,  credits and other  property of any nature
whatsoever  of Borrower now or at any time  hereafter in the  possession  of, in
transit to or from, under the control or custody of, or on deposit with,  Lender
or any Affiliate of Lender.

               Section 9.2 Amendments; Waivers.

               This  Agreement  and the  other  Financing  Documents  may not be
amended,  modified,  or changed in any respect except by an agreement in writing
signed by Lender,  Borrower  and,  so long as MXL is a party to this  Agreement,
MXL.  No  waiver  of any  provision  of this  Agreement  or of any of the  other
Financing Documents or consent to any departure by Borrower therefrom,  shall in
any event be effective unless the same shall be in writing signed by Lender.  No
course of dealing between  Borrower and Lender and no act or failure to act from
time to time on the part of  Lender  shall  constitute  a waiver,  amendment  or
modification  of any provision of this  Agreement or any of the other  Financing
Documents  or any right or remedy under this  Agreement,  under any of the other
Financing Documents or under applicable Laws.



Without implying any limitation on the foregoing:

                    (a) Any waiver or  consent  shall be  effective  only in the
          specific instance,  for the terms and purpose for which given, subject
          to such conditions as Lender may specify in any such instrument.

                    (b) No  waiver  of any  Default  or Event of  Default  shall
          extend to any  subsequent  or other  Default or Event of  Default,  or
          impair any right consequent thereto.

                    (c) No notice to or demand  on  Borrower  in any case  shall
          entitle Borrower to any other or further notice or demand in the same,
          similar or other circumstance.

                    (d) No failure or delay by Lender to insist  upon the strict
          performance  of any term,  condition,  covenant or  agreement  of this
          Agreement or of any of the other Financing  Documents,  or to exercise
          any right,  power or remedy  consequent upon a breach  thereof,  shall
          constitute  a waiver,  amendment  or  modification  of any such  term,
          condition,  covenant  or  agreement  or of any such breach or preclude
          Lender from exercising any such right,  power or remedy at any time or
          times.

                    (e) By  accepting  payment  after the due date of any amount
          payable  under  this  Agreement  or under any of the  other  Financing
          Documents,  Lender  shall not be  deemed to waive the right  either to
          require  prompt  payment when due of all other  amounts  payable under
          this Agreement or under any of the other  Financing  Documents,  or to
          declare a default for  failure to effect  such  prompt  payment of any
          such other amount.

               Section 9.3 Cumulative Remedies.

               The rights, powers and remedies provided in this Agreement and in
the other Financing Documents are cumulative,  may be exercised  concurrently or
separately, may be exercised from time to time and in such order as Lender shall
determine,  subject to the provisions of this Agreement, and are in addition to,
and not exclusive of, rights, powers and remedies provided by existing or future
applicable  Laws. In order to entitle Lender to exercise any remedy  reserved to
it in this Agreement,  it shall not be necessary to give any notice,  other than
such notice as may be expressly required in this Agreement. Without limiting the
generality of the foregoing and subject to the terms of this  Agreement,  Lender
may:

                    (a)  proceed  against  Borrower  with or without  proceeding
          against any other Person (including,  without  limitation,  any one or
          more of  Guarantors)  who may be  liable  (by  endorsement,  guaranty,
          indemnity or otherwise) for all or any part of the Obligations;

                    (b)  proceed  against  Borrower  with or without  proceeding
          under any of the other  Financing  Documents or against any Collateral
          or  other  collateral  and  security  for  all  or  any  part  of  the
          Obligations;




                    (c) without reducing or impairing the obligation of Borrower
          and without notice,  release or compromise with any guarantor or other
          Person  liable  for  all or any  part  of the  Obligations  under  the
          Financing Documents or otherwise;

                    (d)  without   reducing  or  impairing  the  obligations  of
          Borrower and without notice thereof:

                    (i) fail to perfect the Lien in any or all  Collateral or to
               release  any  or  all  the  Collateral  or to  accept  substitute
               Collateral;

                    (ii) approve the making of advances under the Revolving Loan
               under this Agreement;

                    (iii) waive any  provision  of this  Agreement  or the other
               Financing Documents;

                    (iv) exercise or fail to exercise rights of set-off or other
               rights; or

                    (e) accept partial  payments or extend from time to time the
            maturity of all or any part of the Obligations.

               Section 9.4 Severability.

               In case one or more  provisions,  or part  thereof,  contained in
this Agreement or in the other Financing Documents shall be invalid,  illegal or
unenforceable  in any respect  under any Law,  then without need for any further
agreement, notice or action:

                    (a)  the  validity,   legality  and  enforceability  of  the
          remaining provisions shall remain effective and binding on the parties
          thereto and shall not be affected or impaired thereby;

                    (b) the  obligation to be fulfilled  shall be reduced to the
          limit of such validity;

                    (c) if such provision or part thereof  pertains to repayment
          of the  Obligations,  then,  at the sole and  absolute  discretion  of
          Lender,  all of the  Obligations  of Borrower to Lender  shall  become
          immediately due and payable; and

                    (d) if the  affected  provision  or part  thereof  does  not
          pertain  to  repayment  of the  Obligations,  but  operates  or  would
          prospectively  operate to  invalidate  this  Agreement  in whole or in
          material part, then such provision or part thereof only shall be void,
          and the remainder of this Agreement shall remain operative and in full
          force and effect.




               Section 9.5 Assignments by Lender.

               Lender may,  without notice to or consent of Borrower,  assign to
any Person (each an  "Assignee"  and  collectively,  the  "Assignees")  all or a
portion of the Commitment;  provided, however, prior to any sale of the Loan, or
any portion  thereof,  to an institution  organized  under the laws of a foreign
jurisdiction,  so long as no Event of Default exists and is  continuing,  Lender
will provide  notice to Borrower and Borrower  will have the right to approve or
disapprove  the  sale  which  approval  shall  not  be  unreasonably   withheld,
conditioned,  or delayed,  and provided  further,  however,  that the notice and
consent right  provided to Borrower in the  foregoing  clause will only apply to
the sale of an interest in the Loan as part of a  portfolio  management  sale by
Lender, and not any sale of Lender itself.  Lender and its Assignee shall notify
Borrower in writing of the date on which the  assignment is to be effective (the
"Adjustment  Date"). On or before the Adjustment Date, Lender,  Borrower and the
Assignee  shall  execute and deliver a written  assignment  agreement  in a form
acceptable to Lender,  which shall  constitute an amendment to this Agreement to
the extent  necessary  to reflect  such  assignment.  Upon the request of Lender
following an assignment made in accordance with this Section 9.5, Borrower shall
issue  new Notes to Lender  and its  Assignee  reflecting  such  assignment,  in
exchange for the existing Notes held by Lender.

               In addition,  notwithstanding  the  foregoing,  Lender may at any
time pledge all or any  portion of Lender's  rights  under this  Agreement,  the
Commitment or the Obligations to a Federal Reserve Bank.

               Section 9.6 Participations by Lender.

               Lender may at any time sell to one or more financial institutions
participating interests in any of Lender's Obligations or Commitment;  provided,
however,   that  (a)  no  such  participation  shall  relieve  Lender  from  its
obligations  under this Agreement or under any of the other Financing  Documents
to which it is a party,  (b) Lender  shall  remain  solely  responsible  for the
performance of its  obligations  under this Agreement and under all of the other
Financing  Documents to which it is a party,  and (c) Borrower shall continue to
deal solely and directly  with Lender in  connection  with  Lender's  rights and
obligations  under  this  Agreement  and  the  other  Financing   Documents.   A
participant shall have no rights vis-a-vis the Borrower under this Agreement.

               Section 9.7 Disclosure of Information by Lender.

               Subject to the provisions of Section 9.20  (Confidentiality),  in
connection with any sale,  transfer,  assignment or  participation  by Lender in
accordance   with   Section   9.5   (Assignments   by  Lender)  or  Section  9.6
(Participations  by  Lender),  Lender  shall have the right to  disclose  to any
actual or potential purchaser, assignee, transferee or participant all financial
records,  information,  reports,  financial statements and documents obtained in
connection with this Agreement  and/or any of the other  Financing  Documents or
otherwise.

               Section 9.8 Successors and Assigns.

               This Agreement and all other Financing Documents shall be binding
upon and inure to the  benefit  of  Borrower  and  Lender  and their  respective



successors and assigns,  except that Borrower shall not have the right to assign
its rights hereunder or any interest herein without the prior written consent of
Lender.

               Section 9.9 Continuing Agreements.

               All covenants, agreements, representations and warranties made by
Borrower in this Agreement, in any of the other Financing Documents,  and in any
certificate  delivered  pursuant  hereto or thereto  shall survive the making by
Lender of the  Revolving  Loan,  the  issuance  of  Letters  of  Credit  and the
execution and delivery of the Notes,  shall be binding upon Borrower  regardless
of how long before or after the date hereof any of the  Obligations  were or are
incurred,  and shall  continue  in full  force and  effect so long as any of the
Obligations are outstanding and unpaid. From time to time upon Lender's request,
and as a condition of the release of any one or more of the Security  Documents,
Borrower  and other  Persons  obligated  with respect to the  Obligations  shall
provide Lender with such acknowledgments and agreements as Lender may require to
the  effect  that  there  exists no  defenses,  rights of setoff or  recoupment,
claims,  counterclaims,  actions  or  causes  of  action  of any kind or  nature
whatsoever in connection with the  Obligations  against Lender and/or any of its
agents and others, or to the extent there are, the same are waived and released.

               Section 9.10 Enforcement Costs.

               Borrower  shall pay to Lender on demand  all  Enforcement  Costs,
together with interest thereon from the earlier of the date incurred or advanced
until  paid in full at a per annum  rate of  interest  equal at all times to the
Post-Default  Rate.  Enforcement  Costs  shall be  payable  on  demand.  Without
implying any  limitation on the  foregoing,  Borrower  shall pay, as part of the
Enforcement  Costs,  upon  demand  any and all stamp  and  other  Taxes and fees
payable or  determined  to be  payable  in  connection  with the  execution  and
delivery of this Agreement and the other Financing  Documents and to save Lender
harmless from and against any and all  liabilities  with respect to or resulting
from any delay in paying or  omission  to pay any Taxes or fees  referred  to in
this  Section.  The  provisions  of this Section shall survive the execution and
delivery of this  Agreement,  the repayment of the other  Obligations  and shall
survive the termination of this Agreement.

               Section 9.11 Applicable Law; Jurisdiction.

               9.11.1 Applicable Law.

               Borrower  and Lender  acknowledge  and agree that this  Agreement
shall be governed by the Laws of the State.

               9.11.2 Submission to Jurisdiction.

               Borrower  irrevocably submits to the jurisdiction of any state or
federal court sitting in the State over any suit,  action or proceeding  arising
out of or relating to this  Agreement or any of the other  Financing  Documents.
Borrower  irrevocably  waives,  to the  fullest  extent  permitted  by law,  any
objection  that it may now or  hereafter  have to the laying of the venue of any
such suit, action or proceeding brought in any such court and any claim that any
such suit, action or proceeding brought in any such court has been brought in an
inconvenient  forum.  Final  judgment  in any such  suit,  action or  proceeding



brought in any such court shall be conclusive  and binding upon Borrower and may
be enforced in any court in which Borrower is subject to jurisdiction, by a suit
upon such  judgment,  provided that service of process is effected upon Borrower
in one of the manners  specified in this  Section or as  otherwise  permitted by
applicable Laws.

               9.11.3 Service of Process.

               Borrower  hereby  consents to process  being  served in any suit,
action or proceeding of the nature referred to in this Section by the mailing of
a copy thereof by registered or certified mail, postage prepaid,  return receipt
requested,  to  Borrower  at  Borrower's  address  designated  in or pursuant to
Section 9.1 (Notices).  Borrower  irrevocably agrees that such service (y) shall
be deemed in every  respect  effective  service of process upon  Borrower in any
such suit, action or proceeding,  and (z) shall, to the fullest extent permitted
by law, be taken and held to be valid personal service upon Borrower. Nothing in
this  Section  shall  affect the right of Lender to serve  process in any manner
otherwise  permitted  by law or limit  the right of  Lender  otherwise  to bring
proceedings against Borrower in the courts of any jurisdiction or jurisdictions.

               Section 9.12 Duplicate Originals and Counterparts.

               This  Agreement  may be  executed  in  any  number  of  duplicate
originals or  counterparts,  each of such  duplicate  originals or  counterparts
shall be deemed to be an original and all taken  together  shall  constitute but
one and the same instrument.

               Section 9.13 Headings.

               The  headings  in  this   Agreement   are  included   herein  for
convenience  only,  shall not  constitute a part of this Agreement for any other
purpose, and shall not be deemed to affect the meaning or construction of any of
the provisions hereof.

               Section 9.14 No Agency.

               Nothing  herein   contained  shall  be  construed  to  constitute
Borrower as Lender's agent for any purpose  whatsoever or to permit  Borrower to
pledge any of the credit of Lender.  Lender shall not be  responsible  or liable
for any shortage,  discrepancy,  damage,  loss or destruction of any part of the
Collateral wherever the same may be located and regardless of the cause thereof,
unless as a result of Lender's gross  negligence or willful  misconduct.  Lender
shall not, by anything herein or in any of the Financing Documents or otherwise,
assume any of Borrower's obligations under any contract or agreement assigned to
Lender,  and Lender shall not be responsible  in any way for the  performance by
Borrower of any of the terms and conditions thereof.

               Section 9.15 Date of Payment.

               Should the  principal  of or interest on the Notes become due and
payable on other than a Business Day, the maturity  thereof shall be extended to
the next succeeding Business Day and in the case of principal, interest shall be
payable  thereon  at the rate per  annum  specified  in the  Notes  during  such
extension.

               Section 9.16 Entire Agreement.

               This  Agreement  is  intended  by  Lender  and  Borrower  to be a
complete,  exclusive and final  expression of the agreements  contained  herein.



Neither  Lender nor  Borrower  shall  hereafter  have any rights under any prior
agreements  pertaining to the matters addressed by this Agreement but shall look
solely  to this  Agreement  for  definition  and  determination  of all of their
respective rights, liabilities and responsibilities under this Agreement.

               Section 9.17 Waiver of Trial by Jury.

               BORROWER, MXL AND LENDER HEREBY JOINTLY AND SEVERALLY WAIVE TRIAL
BY JURY IN ANY ACTION OR  PROCEEDING  TO WHICH  BORROWER,  MXL AND LENDER MAY BE
PARTIES,  ARISING OUT OF OR IN ANY WAY PERTAINING TO (A) THIS AGREEMENT, (B) ANY
OF THE FINANCING  DOCUMENTS,  OR (C) THE COLLATERAL.  THIS WAIVER  CONSTITUTES A
WAIVER OF TRIAL BY JURY OF ALL CLAIMS  AGAINST  ALL  PARTIES TO SUCH  ACTIONS OR
PROCEEDINGS,  INCLUDING  CLAIMS  AGAINST  PARTIES  WHO ARE NOT  PARTIES  TO THIS
AGREEMENT.

               This  waiver is  knowingly,  willingly  and  voluntarily  made by
Borrower,  MXL and Lender, and Borrower, MXL and Lender hereby represent that no
representations  of fact or opinion have been made by any  individual  to induce
this  waiver of trial by jury or to in any way  modify or  nullify  its  effect.
Borrower,  MXL and Lender further  represent that they have been  represented in
the signing of this  Agreement  and in the making of this waiver by  independent
legal  counsel,  selected  of their  own free  will,  and that they have had the
opportunity to discuss this waiver with counsel.

               Section 9.18 Liability of Lender.

               Borrower  and MXL each hereby  agrees  that  Lender  shall not be
chargeable  for any  negligence,  mistake,  act or omission  of any  accountant,
examiner,  agency  or  attorney  employed  by  Lender  in  making  examinations,
investigations  or  collections,   or  otherwise  in  perfecting,   maintaining,
protecting or realizing upon any lien or security interest or any other interest
in the Collateral or other security for the Obligations.

               By inspecting the Collateral or any other  properties of Borrower
or MXL or by accepting or approving anything required to be observed,  performed
or  fulfilled  by  Borrower  or MXL or to be given to  Lender  pursuant  to this
Agreement or any of the other Financing Documents, Lender shall not be deemed to
have   warranted  or   represented   the   condition,   sufficiency,   legality,
effectiveness or legal effect of the same, and such acceptance or approval shall
not constitute any warranty or representation with respect thereto by Lender.

               Section 9.19 Indemnification.

               Borrower  and MXL each  agrees to  indemnify  and hold  harmless,
Lender,  Lender's  parent and Affiliates and Lender's  parent's and  Affiliates'
officers,  directors,  shareholders,  employees and agents (each an "Indemnified
Party," and collectively,  the "Indemnified Parties"),  from and against any and
all claims,  liabilities,  losses,  damages,  costs and expenses (whether or not
such  Indemnified  Party  is a  party  to  any  litigation),  including  without
limitation,  reasonable  attorney's  fees and costs and costs of  investigation,
document production,  attendance at depositions or other discovery,  incurred by
any Indemnified Party with respect to, arising out of or as a consequence of (a)



this  Agreement  or any of the  other  Financing  Documents,  including  without
limitation,   any  failure  of  Borrower  to  pay  when  due  (at  maturity,  by
acceleration or otherwise) any principal,  interest, fee or any other amount due
under this  Agreement or the other  Financing  Documents,  or any other Event of
Default (b) the use by  Borrower of any  proceeds  advanced  hereunder;  (c) the
transactions  contemplated  hereunder; or (d) any claim, demand, action or cause
of action being asserted against (i) Borrower, MXL or any of their Affiliates by
any other Person, or (ii) any Indemnified Party by Borrower or MXL in connection
with the transactions contemplated hereunder. Notwithstanding anything herein or
elsewhere  to the  contrary,  neither  Borrower or MXL shall not be obligated to
indemnify or hold harmless any  Indemnified  Party from any  liability,  loss or
damage  resulting  from the gross  negligence,  willful  misconduct  or unlawful
actions  of such  Indemnified  Party.  Any amount  payable to Lender  under this
Section  will bear  interest  at the  Post-Default  Rate from the due date until
paid.

               Section 9.20 Confidentiality.

               Lender  understands that some of the information  furnished to it
pursuant to this Agreement and the other Financing  Documents may be received by
it prior to the time that such  information  shall  have been made  public,  and
Lender  hereby  agrees  that it will  keep,  and will  direct its  officers  and
employees to keep, all the information provided to it pursuant to this Agreement
and the other  Financing  Documents  confidential  prior to its becoming  public
subject,  however,  to  (a)  disclosure  to  officers,   directors,   employees,
representatives, agents, auditors, consultants, advisors, lawyers and Affiliates
of Lender, in the ordinary course of business,  (b) disclosure to such officers,
directors,  employees,  agents and representatives of a prospective  assignee or
participant as need to know such  information in connection  with the evaluation
of a possible  participation  in the  Commitment  (who will be  informed  of the
confidential  nature of the  material),  or (c) the  obligations  of Lender or a
participant  under  applicable  Law,  or pursuant  to  subpoenas  or other legal
process, to make information available to governmental agencies and examiners or
to others  and the right of Lender to use such  information  in  proceedings  to
enforce  their  rights  and  remedies  hereunder  or under any  other  Financing
Documents or in any proceeding  against Lender in connection with this Agreement
or under any other Financing Document or the transactions contemplated hereunder
or thereunder.


               Notwithstanding the foregoing,  each of Lender,  Borrower and any
assignee or participant  hereunder (and each employee,  representative  or other
agent of such parties) may disclose to any and all Persons,  without  limitation
of any kind,  the tax  treatment  and any facts that may be  relevant to the tax
structure  of the  transaction;  provided,  however,  that no such Person  shall
disclose any information that is not relevant to understanding the tax treatment
and structure of the  transaction  (including  the identity of any party and any
information that could lead another to determine the identity of any party),  or
any information to the extent that such  disclosure  could result in a violation
of any federal or state securities law or any stock exchange regulation.


               IN WITNESS WHEREOF,  each of the parties hereto have executed and
delivered this  Agreement  under their  respective  seals as of the day and year
