       any Invoice are, or are not, EXIM Qualified, QUALCOMM may, but shall not
       be obligated to, redesignate Tranche A Loans, in whole or part, in order
       of priority according to availability, to be Tranche C Loans or Tranche B
       Loans and, upon written notice to Administrative Agent, with a copy
       thereof to Borrower, the interest accrued pursuant to each such
       redesignated Loan shall be retroactively adjusted and paid, or credited,
       as applicable, on the next succeeding Interest Payment Date; provided
       further, that with respect to Loans made under Facility-

                                       2.
<PAGE>

       2, the foregoing references to Tranche C Loans, and designation and
       redesignation of Loans as Tranche C Loans shall be ignored.

       1.2 TYPES OF LONG-TERM LOANS. Each Long-Term Loan shall, in accordance
with the terms of this Agreement, be in the form of either a Base Rate Loan or a
Eurodollar Loan; provided, however, that, notwithstanding anything to the
contrary herein, each initial borrowing of Long-Term Loans pursuant to SECTION
1.5(b) hereof shall be comprised solely of Base Rate Loans until the first
Business Day of the calendar month next succeeding the effective date of such
initial borrowing of such Loans but may as of such Business Day be converted
into Eurodollar Loans and continued as provided in SECTION 1.3 hereof. At no
time may Borrower maintain Eurodollar Loans in more than six (6) separate
Interest Periods in respect of Facility-1 Loans and six (6) separate Interest
Periods in respect of Facility-2 Loans.

       1.3 CONVERSION AND CONTINUATION ELECTIONS. Borrower may, upon irrevocable
written notice to Administrative Agent, with reference to the Long-Term Loans:

              (a) elect to convert on any Business Day, Base Rate Loans in an
amount equal to Two Million Five Hundred Thousand ($2,500,000) (or any integral
multiple of One Hundred Thousand Dollars ($100,000) in excess thereof) into
Eurodollar Loans; or

              (b) elect to convert any Eurodollar Loans into Base Rate Loans on
the last day of the Interest Period applicable to such Eurodollar Loans; or

              (c) elect to continue any Eurodollar Loans (or any part thereof in
an amount equal to Two Million Five Hundred Thousand Dollars ($2,500,000) or any
integral multiple of One Hundred Thousand Dollars ($100,000) in excess thereof)
as Eurodollar Loans on the last day of the Interest Period applicable to such
Eurodollar Loans.

       1.4 DURATION OF INTEREST PERIODS.

              (a) Subject to the provisions of the definition of Interest Period
and SECTION 1.2 and SECTION 1.3 above, the duration of each Interest Period
applicable to a Eurodollar Loan shall be as specified in the applicable Notice
of Conversion/Continuation.

              (b) If Administrative Agent does not receive a notice of election
of duration of an Interest Period with respect to a borrowing of Eurodollar
Loans pursuant to SUBSECTION (a) above within the applicable time limits
specified herein, Borrower shall be deemed to have elected to make or convert
such Loans in whole into Eurodollar Loans with an Interest Period of one month
on the last day of the then current Interest Period with respect thereto.
Notwithstanding anything to the contrary herein, any and all Eurodollar Loans
shall be converted in whole into Base Rate Loans on the last day of the then
existing Interest Period with respect thereto if Administrative Agent shall have
received notice from Borrower or a Lender that an Event of Default exists and
Administrative Agent, at the direction of Required Lenders shall have delivered
to Borrower notice that such conversion is required.

       1.5 EXISTING LOANS AND NOTICE AND MANNER OF MAKING ADDITIONAL LOANS OR
           CONVERTING/CONTINUING LONG-TERM LOANS.

              (a) EXISTING LOANS. Set forth on SCHEDULE 1.5 hereto is a schedule
of all amounts currently due or to become due under the QUALCOMM Procurement
Agreements which the parties have agreed, on the Effective Date, are to be
financed under Facility-1. Each such amount shall be deemed to be Tranche A
Loans, Tranche B Loans or Tranche C Loans thereunder, outstanding under the
Notes, if applicable, on and after the Effective Date. SCHEDULE 1.5 also sets
forth a schedule of all Pagares outstanding on the Effective Date which the
parties have agreed will be financed under the VAT Facility and shall continue
to be outstanding on the terms set forth therein and shall be treated as VAT
Loans hereunder on and after the Effective Date.

              (b) NOTICE AND MANNER OF MAKING ADDITIONAL LOANS.

                     (i) Not fewer than five (5) Business Days prior to the date
Borrower desires to borrow hereunder, Borrower shall deliver by electronic
facsimile transmission: (A) to each of Administrative Agent and QUALCOMM,
written notice specifying (1) whether the requested Loan shall be made in cash
(a "Cash Advance") or by means of a credit (a "Credit Advance") against amounts
due to the applicable Vendor under the QUALCOMM Procurement Agreements, (2) the
amount of such Borrowing which, in the case of a Cash Advance under either
Long-Term Facility shall not be less than the Minimum Borrowing Amount, (3) with
respect to requests of Cash Advances not made to Borrower, the Person to which
such Cash Advance is requested to be made on behalf of Borrower and (4) the
effective date for such Borrowing of Loans (which for Credit Advances shall be
no earlier than the date on which payment is due under the QUALCOMM Procurement
Agreements), which notice shall be in the form of EXHIBIT C to this Agreement
(an "Loan Request"); and (B) to QUALCOMM, all invoices and any other supporting
documentary information necessary to evidence the QUALCOMM Costs and VAT, if
applicable, giving rise to such Loan Request (the "Invoices). After the date on
which QUALCOMM receives each Loan Request and the accompanying Invoices,
QUALCOMM shall have four (4) Business Days (the "Loan Request Review Period")
during which to acknowledge receipt of the same and transmit such to
Administrative Agent. Provided that QUALCOMM has acknowledged receipt of such
Loan Request and such Invoices to Administrative Agent in writing or, if
QUALCOMM has not so acknowledged within the Loan Request Review Period, the
effective date for such borrowing of such Loans under Credit Advances shall be
the first (1(st)) Business Day after the final day of such Loan Request Review
Period and the applicable Invoice shall be deemed paid to the extent of such
Loan.

                     (ii) On each date prior to the end of the Facility-1
Availability Period or the Facility-2 Availability Period, as applicable, on
which payment under the QUALCOMM Procurement Agreements is due to QUALCOMM for
which Borrower has delivered an Invoice, and such payment has not been made or a
borrowing of Long-Term Loans has not been requested by Borrower pursuant to
SECTION 1.5(b)(i) hereof, QUALCOMM shall deliver to Administrative Agent by
electronic facsimile transmission written notice of such due date and the amount
of such payment due under the QUALCOMM Procurement Agreements (less any amounts
as to which QUALCOMM and the Administrative Agent have received written notice
from Borrower of any dispute with respect to such amount being due and payable),
which notice

                                       4.
<PAGE>

shall be in the form of EXHIBIT D to this Agreement (a "Notice of Deemed Loan"),
and a borrowing of Base Rate Loans (which Loans shall be Tranche A Loans,
Tranche B Loans or Tranche C Loans as shall be determined pursuant to SECTION
1.1(e)) shall be deemed to have been made as of the date on which such payment
was due pursuant to the QUALCOMM Procurement Agreements and the amount of
Long-Term Loans owing to each Lender shall automatically be increased as of such
date to add to the principal amount thereof the amount of such required payment
according to the Commitment of each Lender making such Long-Term Loan; provided,
however, that Borrower may thereafter, elect to convert such Long-Term Loans in
whole or in part to Eurodollar Loans in accordance with SECTION 1.5(c) below.

                     (iii) With regard to Long-Term Loans which are Credit
Advances: (A) to the extent that, with respect to any Lender, the amount equal
to such Lender's Percentage under the applicable Facility multiplied by the
aggregate amount required to be paid by Borrower at such time under the QUALCOMM
Procurement Agreements exceeds amounts owing to such Lender under the QUALCOMM
Procurement Agreements on such date, such Lender shall, by 12:00 noon New York
time on such date, remit by wire transfer such excess to Administrative Agent;
and (B) to the extent that, with respect to any Lender, the amount equal to such
Lender's Percentage under the applicable Facility multiplied by the aggregate
amount required to be paid by Borrower at such time under the QUALCOMM
Procurement Agreements is less than the amount reported by QUALCOMM to
Administrative Agent as amounts owing to such Lender under the QUALCOMM
Procurement Agreements on such date, Administrative Agent shall promptly remit
(from amounts received by Administrative Agent pursuant to (A) above) by wire
transfer such shortfall to such Lender.

                     (iv) With regard to Loan Requests for Cash Advances,
Administrative Agent shall promptly notify each Lender having a Commitment with
respect thereto as to the content of each Loan Request for Cash Advances and
whether or not QUALCOMM has advised Administrative Agent that the conditions set
forth in the second sentence of SECTION 1.5(b)(i) have been satisfied. Provided
that QUALCOMM has acknowledged Borrower's Loan Request to Administrative Agent
in writing, such Lenders shall disburse to Administrative Agent in immediately
available funds by 12:00 noon New York time on the requested funding date an
amount equal to their respective Percentages multiplied by the amount of the
borrowing requested in such Loan Request, and Administrative Agent shall
promptly disburse the aggregate of such amounts in immediately available funds
to Borrower or such other Person designated by Borrower in the Loan Request.

              (c) CONVERSIONS/CONTINUATIONS OF LOANS. On each date on which
Borrower desires, with respect to Long-Term Loans to (A) continue any such
Long-Term Loans that are Eurodollar Loans for another Interest Period, or (B)
convert any such outstanding Long-Term Loans into Long-Term Loans of another
type provided for in this Agreement, Borrower shall notify Administrative Agent
(which notice shall be irrevocable) in writing by electronic facsimile
transmission received no later than 1:00 p.m. New York time on the date one (1)
Business Day before the day on which such requested Long-Term Loans are to be
converted into Base Rate Loans, and received no later than 1:00 p.m. New York
time on the date three (3) Business Days before the date on which such requested
Long-Term Loans are to be continued for another Interest Period as or converted
into Eurodollar Loans. Such notice shall specify (i) the effective date and
amount of such Long-Term Loans or portion thereof to be continued or converted,

                                       5.
<PAGE>

subject to the limitations set forth in SECTION 1.3 hereof, (ii) the interest
rate option to be applicable thereto, and (iii) the duration of the applicable
Interest Period, if any (subject to the provisions of the definition of Interest
Period and SECTION 1.4) hereof. Each such notification (a "Notice of
Conversion/Continuation") shall be in the form of EXHIBIT E to this Agreement.

              (d) Administrative Agent shall promptly notify each Lender as to
the content of each Loan Request, Notice of Deemed Loan, and Notice of
Conversion/Continuation.

              (e) Unless Administrative Agent shall have been notified by any
Lender no later than the Business Day prior to the respective funding date of
any borrowing of Loans that such Lender does not intend to make available to
Administrative Agent immediately available funds equal to such Lender's
Percentage under the relevant Facility of the total principal amount of such
borrowing, Administrative Agent may (in its sole and absolute discretion) assume
that such Lender has advanced funds in the amount of such Lender's relevant
Percentage of such borrowing to Administrative Agent on the applicable funding
date and Administrative Agent may, in reliance upon such assumption, make
available to Borrower corresponding funds. Administrative Agent agrees to give
prompt notice to Borrower in the event it advances funds on behalf of a Lender
under this SECTION 1.5(e); provided that failure to give such notice shall in no
way limit, restrict or otherwise affect Borrower's obligations or Administrative
Agent's or any Lender's rights or remedies under this Agreement and the other
Credit Documents. If Administrative Agent has made funds available to Borrower
based on such assumption and such Loan is not in fact made available to
Administrative Agent by such Lender, Administrative Agent shall be entitled to
recover the corresponding amount of such Long-Term Loan on demand from such
Lender. If such Lender does not promptly pay such corresponding amount upon
Administrative Agent's demand, Administrative Agent shall notify Borrower and
Borrower shall repay such Long-Term Loan to Administrative Agent, together with
accrued interest thereon. Administrative Agent also shall be entitled to recover
from such Lender interest on such Long- Term Loan in respect of each day from
the date such Long-Term Loan was made by Administrative Agent to Borrower to the
date such corresponding amount is recovered by Administrative Agent at the
Federal Funds Effective Rate.

              (f) Nothing herein shall be deemed to relieve any Lender from its
obligation to fulfill its commitments hereunder or to prejudice any rights which
Borrower may have against any Lender as a result of any default by such Lender
hereunder.

       1.6 EVIDENCE OF DEBT.

              (a) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing indebtedness of Borrower to such
Lender resulting from each Loan made by such Lender from time to time, including
the amounts of principal and interest payable and paid to such Lender from time
to time under this Agreement.

              (b) Administrative Agent shall maintain the Lender Register
pursuant to SECTION 11.16, and a subaccount therein for each Lender, in which
shall be recorded (i) the amount of each Loan made hereunder, and each Interest
Period applicable thereto, (ii) the amount of any principal or interest due and
payable or to become due and payable from Borrower to each Lender hereunder
(including the amount of any capitalized interest under

                                       6.
<PAGE>

SECTION 1.8(e)) and (iii) both the amount of any sum received by Administrative
Agent hereunder from Borrower and each Lender's share thereof.

              (c) The entries made in the Lender Register and the accounts of
each Lender maintained pursuant to SECTION 1.6(b) shall, to the extent permitted
by applicable law, be prima facie evidence of the existence and amounts of the
obligations of Borrower therein recorded; provided, that the failure of
Administrative Agent or any Lender to maintain the Lender Register or any such
account, or any error therein, shall not in any manner affect the obligation of
Borrower to repay (with applicable interest) the Loans of each Lender in
accordance with the terms of this Agreement.

              (d) Borrower agrees that, upon the request to Administrative Agent
by any Lender under any Facility other than the VAT Facility, Borrower will
execute and deliver to such Lender a promissory note of Borrower, which shall be
jointly and severally guaranteed "avalados" by the Guarantors, dated the first
day of the Availability Period for such Facility evidencing the Loans under such
Facility of such Lender, substantially in the form of EXHIBIT A with appropriate
insertions as to date and principal amount (each, a "Note"). Thereafter, the
Loans evidenced by any such Note and interest thereon shall at all times
(including after assignment pursuant to SECTION 11.4) be represented by one or
more promissory notes in such form payable to the order of the payee named
therein.

              (e) Borrower agrees that Borrower will execute and deliver to each
Lender making a VAT Loan a Pagare, which shall be jointly and severally
guaranteed "avalados" by the Guarantors, dated the date of issuance of such
Pagare evidencing the VAT Loan made on that date. Thereafter, the VAT Loan
evidenced by such Pagare and interest thereon shall at all times (including
after assignment pursuant to SECTION 11.4) be represented by such Pagare in such
form payable to the order of the payee named therein.

       1.7 PRO RATA BORROWINGS. All Loans under this Agreement shall be made by
the Lenders pro rata on the basis of Commitments of the Lenders with a
Commitment under the Facility under which such Loan is being made. It is
understood that no Lender shall be responsible for any default by any other
Lender in its obligation to make Loans hereunder and that each Lender shall be
obligated to make the Loans provided to be made by it hereunder, regardless of
the failure of any other Lender to fulfill its commitments hereunder.

       1.8 INTEREST.

              (a) Except as provided in the next sentence with respect to VAT
Loans and as contemplated in SECTION 1.1(e), the unpaid principal amount of each
Loan shall bear interest from the date of the incurrence thereof until payment
maturity (whether by acceleration or otherwise) at a rate per annum which shall
at all times (i) in the case of Eurodollar Loans, and during each Interest
Period applicable thereto, be the Eurodollar Rate for such Interest Period plus
the relevant Applicable Margin and (ii) in the case of Base Rate Loans, be the
Base Rate plus the relevant Applicable Margin. The unpaid principal amount of
each VAT Loan shall bear interest from the date of the incurrence thereof until
payment maturity (whether by acceleration or otherwise) at a fixed rate per
annum which shall at all times be the Applicable VAT Margin

                                       7.
<PAGE>

plus the Eurodollar Rate in effect on the date of issuance of the Pagare
associated with such VAT Loan (assuming an Interest Period of six months
commencing on such date).

              (b) All overdue principal and, to the extent permitted by law,
overdue interest in respect of each Loan and any other overdue amount payable
hereunder shall bear interest at a rate per annum equal to the rate otherwise
applicable thereto plus two percent (2%) per annum.

              (c) Except as provided in the next sentence with respect to VAT
Loans, interest shall accrue from and including the date of the incurrence of
Loans to but excluding the date of any repayment thereof and shall be payable
(i) in the case of Base Rate Loans, on the last Business Day of each calendar
quarter, and (ii) in the case of each Eurodollar Loan, on the last day of each
Interest Period applicable thereto and, in the case of an Interest Period in
excess of three months, on each date occurring at three month intervals after
the first day of such Interest Period and (iii) in the case of all Loans, on any
prepayment (on the amount prepaid), at maturity (whether by acceleration or
otherwise) and, after such maturity, on demand. Interest shall accrue from and
including the date of the incurrence of each VAT Loan to but excluding the date
of any repayment thereof and shall be payable on any prepayment (on the amount
prepaid), at maturity (whether by acceleration or otherwise) and, after such
maturity, on demand.

              (d) All computations of interest hereunder shall be made in
accordance with SECTION 11.7(b).

              (e) Anything in this Agreement to the contrary notwithstanding,
and unless Borrower shall notify Administrative Agent that this SECTION 1.8(e)
shall not be applicable to any of the interest payments on the Tranche A Loans
or the Tranche C Loans otherwise covered hereby, (i) the interest that accrues
on Tranche A Loans shall not be required to be paid in cash on any Interest
Payment Date occurring prior to the Facility-1 Refinancing Date and (ii) the
interest that accrues on Tranche C Loans shall not be required to be paid in
cash on any Interest Payment Date occurring prior to the first anniversary of
the Effective Date, but, in each case, on each such Interest Payment Date such
accrued interest will be capitalized and added to the principal of the Tranche A
Loans or Tranche C Loans of each Lender as to which such interest accrued.

              (f) Administrative Agent, upon determining the interest rate for
any Borrowing of Eurodollar Loans for any Interest Period shall promptly notify
Borrower and the Lenders thereof.

       1.9 INCREASED COSTS, ILLEGALITY, ETC.

              (a) In the event that (x) in the case of clause (i) below,
Administrative Agent or (y) in the case of clauses (ii) and (iii) below, any
Lender shall have determined in good faith (which determination shall, absent
manifest error, be final and conclusive and binding upon all parties hereto):

                     (i) on any date for determining the Eurodollar Rate for any
Interest Period that, by reason of any changes arising after the date of this
Agreement affecting the interbank Eurodollar market, adequate and fair means do
not exist for ascertaining the applicable interest rate on the basis provided
for in the definition of Eurodollar Rate; or

                                       8.
<PAGE>

                     (ii) at any time, that such Lender shall incur increased
costs or reductions in the amounts received or receivable hereunder with respect
to any Eurodollar Loans (other than taxes covered by SECTION 3.4 and any
increased cost or reduction in the amount received or receivable resulting from
the imposition of or a change in the rate of taxes or similar charges) because
of (x) any change since the Effective Date in any applicable law, governmental
rule, regulation, guideline or order (or in the interpretation or administration
thereof and including the introduction of any new law or governmental rule,
regulation, guideline or order) (such as, for example, but not limited to, a
change in official reserve requirements) and/or (y) other circumstances
affecting the interbank Eurodollar market or the position of such Lender in such
market; or

                     (iii) at any time, that the making or continuance of any
Eurodollar Loan has become unlawful by compliance by such Lender in good faith
with any law, governmental rule, regulation or guideline introduced or changed
after the Effective Date;

then, and in any such event, such Lender (or Administrative Agent in the case of
clause (i) above) shall (x) on such date and (y) within ten Business Days of the
date on which such event no longer exists give notice (by telephone confirmed in
writing) to Borrower and to Administrative Agent of such determination (which
notice Administrative Agent shall promptly transmit to each of the other
Lenders). Thereafter (x) in the case of clause (i) above, until such time as
Administrative Agent notifies Borrower and the Lenders that the circumstances
giving rise to such notice by Administrative Agent no longer exist, all new
Loans, and all outstanding Loans as to which existing Interest Periods expire,
shall bear interest at a rate per annum equal to (A) the Base Rate plus (B) the
Applicable Margin, (y) in the case of clause (ii) above, Borrower shall pay to
such Lender, upon written demand therefor, such additional amounts (in the form
of an increased rate of, or a different method of calculating, interest or
otherwise as such Lender in its reasonable discretion shall determine after
consultation with Borrower) as shall be required to compensate such Lender for
such increased costs or reductions in amounts receivable hereunder (a written
notice as to the additional amounts owed to such Lender, describing the basis
for such increased costs and showing the calculation thereof, submitted to
Borrower by such Lender shall, absent manifest error, be final and conclusive
and binding upon all parties hereto) and (z) in the case of clause (iii) above,
the obligations of such Lender to make and maintain Loans hereunder under the
respective Facilities shall terminate and all of the outstanding Loans made by
it shall be repaid.

              (b) If any Lender shall have determined that the adoption or
effectiveness after the Effective Date of any applicable law, rule or regulation
regarding capital adequacy, or any change therein after the Effective Date, or
any change after the Effective Date in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by such Lender
or its parent corporation with any request or directive made after the Effective
Date regarding capital adequacy (whether or not having the force of law) of any
such authority, central bank or comparable agency, has or would have the effect
of reducing the rate of return on such Lender's or its parent corporation's
capital or assets as a consequence of its commitments or obligations hereunder
to a level below that which such Lender or its parent corporation could have
achieved but for such adoption, effectiveness, change or compliance (taking into
consideration such Lender's or its parent corporation's policies with respect to
capital adequacy),

                                       9.
<PAGE>

then from time to time, within 15 days after demand by such Lender (with a copy
to Administrative Agent), Borrower shall pay to such Lender such additional
amount or amounts as will compensate such Lender or its parent corporation for
such reduction. Each Lender, upon determining in good faith that any additional
amounts will be payable pursuant to this SECTION 1.9(b), will give prompt
written notice thereof to Borrower, which notice shall describe the basis for
such claim and set forth the calculation of such additional amounts, although
the failure to give any such notice shall not release or diminish any of
Borrower's obligations to pay additional amounts pursuant to this SECTION 1.9(b)
upon the subsequent receipt of such notice;

              (c) Notwithstanding the foregoing, a Lender shall not be entitled
to receive reimbursement for claimed costs pursuant to this SECTION 1.9 incurred
more than 15 months prior to the date Lender provides notice of a claim for
reimbursement.

       1.10 COMPENSATION. Borrower shall compensate each Lender, upon its
written request (which request shall set forth the basis for requesting such
compensation), for all losses, expenses and liabilities (including, without
limitation, any loss, expense or liability incurred by reason of the liquidation
or reemployment of deposits or other funds required by such Lender to fund its
Eurodollar Loans but excluding in any event the loss of anticipated profits)
which such Lender may sustain: (i) if for any reason (other than a default by
such Lender or Administrative Agent) Eurodollar Loans are not incurred on a date
specified therefor in a Borrowing Notice (whether or not withdrawn by Borrower);
(ii) if any prepayment or repayment of any of its Eurodollar Loans (other than
VAT Loans) occurs on a date which is not the last day of an Interest Period
applicable thereto; (iii) if any prepayment of any of its Eurodollar Loans
(other than VAT Loans) is not made on any date specified in a notice of
prepayment given by Borrower; or (iv) as a consequence of any other default by
Borrower to repay its Eurodollar Loans when required by the terms of this
Agreement.

       1.11 CHANGE OF LENDING OFFICE. Each Lender agrees that, upon the
occurrence of any event giving rise to the operation of SECTION 1.9(a)(ii) or
(iii), 1.9(b) or 3.4 with respect to such Lender, it will, if requested by
Borrower, use reasonable efforts (subject to overall policy considerations of
such Lender) to designate another lending office for any Loans affected by such
event, provided that such designation is made on such terms that such Lender and
its lending office suffer no material economic, legal or regulatory
disadvantage, with the object of avoiding the consequence of the event giving
rise to the operation of any such Section. Nothing in this SECTION 1.11 shall
affect or postpone any of the obligations of Borrower or the right of any Lender
provided in SECTION 1.9, 1.10 or 3.

       1.12 EXIM FINANCING, ETC. QUALCOMM shall have the right to (i) attempt to
arrange and arrange at any time one or more EXIM Financings for each or both
Long-Term Facilities, with the entering into of such EXIM Financings to reduce
the respective Facility-1 Commitments and Facility-2 Commitments, as the case
may be, as provided for in SECTION 2.3; and/or (ii) attempt to arrange and
arrange for the Loans to be refinanced by other means, including a
subparticipation of the Commitments or a debt issue in the public markets (each
refinancing described in clause (i) or (ii), a "Refinancing") provided, however,
that Borrower shall not be obliged to agree to any Refinancing if the structure,
costs, and other terms and conditions and other relevant factors concerning the
financing provided under any such Refinancing are not in the best commercial
interests of Borrower as compared to the structure,

                                      10.
<PAGE>

costs, and other terms and conditions and other relevant factors concerning the
financing provided under this Agreement as they relate to the Loans and/or
Commitments to be refinanced, provided, further, that if Borrower and QUALCOMM
disagree as to whether the terms of any proposed Refinancing are in the best
commercial interests of Borrower, the parties shall submit the matter to an
independent, third party and internationally recognized investment banking firm
mutually agreeable to the parties for its determination, which determination
shall be binding on the parties hereto; and/or (iii) attempt to arrange and
arrange for a syndication that complies with the requirements of SECTION 11.4 of
the Commitments and Loans (a "Syndication"), it being agreed that Borrower and
each Credit Party will cooperate with QUALCOMM to negotiate in good faith any
such Refinancing and facilitate any such Syndication, provided, however, that
QUALCOMM shall not within the 18 month period following the Effective Date, (x)
the Borrower shall not be obligated to, and QUALCOMM shall not attempt to
arrange, any refinancing of the type referred to in clause (ii) above and (y)
QUALCOMM shall not solicit any potential Lender in connection with such
Syndication which potential Lender is actively participating in the market for
transactions similar to the Senior Bank Financing or the High Yield Debt
financing; provided, further, that Borrower shall not be obligated to cooperate
in any such attempted Syndication by QUALCOMM more than three (3) times. In
connection with any such Refinancing or Syndication, Borrower may request that
proposed participants therein shall enter into a Common Terms Agreement and if
so requested, it shall also be a condition of such Refinancing or Syndication
that such proposed participants enter the Common Terms Agreement.

       1.13 COMMON TERMS AGREEMENT; CONFORMANCE TO PARI PASSU DEBT.

              (a) A Borrower expects that it will desire to enter into an
agreement (the "Common Terms Agreement") with all holders from time to time of
Pari Passu Debt setting forth the intercreditor arrangements among all such
holders and creating certain common terms. Each Lender hereto hereby agrees that
they will become party to the Common Terms Agreement to the extent reasonably
satisfactory to QUALCOMM and such Lender. Notwithstanding anything in this
Agreement to the contrary, neither Administrative Agent, Collateral Agent nor
any Lender shall be obligated to enter into any agreement whereby it is required
to waive or modify the conditions precedent set forth in SECTION 4, or any
obligation relating to the Collateral or Borrower's obligation to satisfy such
conditions as required under SECTION 6.17.

              (b) SENIOR BANK FINANCING COMMON TERMS. Borrower and each Lender
hereby agree that in connection with Borrower's negotiation of the Senior Bank
Financing they shall negotiate with each other in good faith to promptly amend
and restate this Agreement, and enter into a Common Terms Agreement with the
holders of Pari Passu Debt, as necessary and appropriate to conform covenants
and events of defaults in this Agreement with those applicable to the Senior
Bank Financing to the extent such terms of the Alcatel Credit Agreement are
conformed to such terms governing the Pari Passu Debt.

              (c) ALCATEL COMMON TERMS. Borrower and each Lender hereby agree
that upon completion of the Alcatel Credit Agreement they shall negotiate with
each other in good faith to promptly amend and restate this Agreement, and enter
into a Common Terms Agreement with Alcatel Lender, as necessary and appropriate
to make any inconsistencies between the terms of this Agreement which relate to
interest rate, amortization, fees, representations and warranties,

                                      11.
<PAGE>

covenants, conforming changes, and events of default and the comparable terms in
the Alcatel Credit Agreement conform to the Alcatel Credit Agreement; provided,
however, that no such amendment shall have the effect of changing the terms of
this Agreement retroactively to apply to any period prior to the date of the
Alcatel Credit Agreement.

              (d) ADDITIONAL CREDIT SUPPORT. To the extent that Alcatel Lender
or any other provider of vendor financing to the Borrower Group shall, during
any period from the date hereof through that date eighteen (18) months following
the Effective Date, enjoy any credit support or security therefor from any
shareholder of Holdings or their Affiliates, then such credit support and any
security therefor, shall be immediately provided to Administrative Agent and
Lenders hereunder on a pari passu basis.

       1.14 NO NET PAYMENTS. Borrower's obligation to make payments and perform
all other obligations hereunder, and the rights of Administrative Agent and
Lenders in and to such payments and performance, shall be absolute and
unconditional and shall not be subject to any abatement, reduction, set-off,
defense, counterclaim or recoupment for any reason whatsoever, including,
without limitation, abatements or reductions due to any present or future claims
of any Credit Party or their respective Affiliates against Administrative Agent,
Collateral Agent or any Lender under this Agreement, the QUALCOMM Procurement
Agreements or otherwise, against any vendor of equipment or services used or
planned to be used as part of the System, or against any other Person for
whatever reason. Except as otherwise expressly provided herein, this Agreement
shall not terminate, nor shall the obligations of Borrower be affected, by
reason of (a) any defect in or damage to, or any loss or destruction of, any of
the equipment or services provided pursuant to the QUALCOMM Procurement
Agreements or otherwise becoming part of the System from any cause whatsoever,
(b) the interference with the use of the System by Administrative Agent,
Collateral Agent, any Lender or any other Person, (c) any defect in title to the
System or any part thereof or any Lien on such title, or (d) any bankruptcy,
insolvency, reorganization or other proceeding relating to, or any action taken
by any trustee or receiver of, Administrative Agent, any Lender or any other
Person, or (e) for any other cause, whether similar or dissimilar to the
foregoing, any present or future law or regulation to the contrary
notwithstanding, whether or not such cause shall give rise to a claim by any
Credit Party or their respective Affiliates against any Lender under the
QUALCOMM Procurement Agreements or otherwise, it being the express intention of
the parties hereto that all amounts payable by Borrower hereunder shall be, and
continue to be, payable in all events unless the obligation to pay shall be
terminated pursuant to the express provisions of this Agreement. All payments
made by Borrower hereunder as required hereby shall be final, and Borrower shall
not seek to recover any such payment or any part thereof for any reason
whatsoever. Nothing in this Agreement shall, however, release or waive any claim
Borrower may have against Administrative Agent, any Lender or any other Person,
whether in connection with the QUALCOMM Procurement Agreements or otherwise. If
for any reason whatsoever this Agreement shall be terminated in whole or in part
by operation of law or otherwise, Borrower shall nonetheless, to the extent
permitted by applicable law, pay to Administrative Agent, on behalf of Lenders,
an amount equal to each payment payable hereunder at the time and in the manner
that such payment would have become due and payable under the terms of this
Agreement if it had not been terminated in whole or in part.

                                      12.

       1.15 REPLACEMENT OF LENDERS Upon the occurrence of any event giving rise
to the operation of SECTION 1.9(b) or SECTION 3.04 with respect to any Lender

of those being charged generally by the Lenders or if a Lender has defaulted on
its obligation to make Loans hereunder, Borrower shall have the right, if no
Default or Event of Default then exists, to replace such Lender (the "Replaced
Lender") with one or more other Eligible Transferee (collectively, the

to such Replaced Lender concurrently with such replacement. Upon the execution
of the respective Assignment Agreement, the payment of amounts referred to in

withholding, social security, sales, use, service, leasing excise, franchise,
value added, estimated, occupation, real and personal property, stamp, transfer,
workers' compensation, severance or other taxes, levies, imposts, duties, fees,
assessments or other charges of whatever nature now or hereafter imposed by any
jurisdiction or by any political subdivision or taxing authority thereof or
therein with respect to such payments (but excluding, except as provided in the
third succeeding sentence, any tax imposed on or measured by the net income or
net profits of a Lender pursuant to the laws of the jurisdiction in which it is
organized or any jurisdiction in which such Lender maintains a place of business
or any subdivision thereof or therein) and all interest, penalties addition
thereto or similar liabilities with respect to such nonexcluded taxes, levies,
imposts, duties, fees, assessments or other charges (all such nonexcluded taxes,
levies, imposts, duties, fees, assessments or other charges being referred to
collectively as "Taxes"). In addition, Borrower shall pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other Credit Documents (hereinafter referred to as "Other
Taxes"). If any Taxes or Other Taxes are so levied or imposed, Borrower agrees
to pay the full amount of such Taxes or Other Taxes, and such additional amounts
as may be necessary so that every payment of all amounts due under this
Agreement or under any Note or Pagare, after withholding or deduction for or on
account of any Taxes or Other Taxes, will not be less than the amount provided
for herein or in such Note or Pagare. If any amounts are payable in respect of
Taxes or Other Taxes pursuant to the foregoing, Borrower agrees to reimburse
such amounts to each Lender, upon the written request of such Lender, such Taxes
or Other Taxes as are imposed on or measured by the net income or net profits of
such Lender pursuant to the laws of the jurisdiction in which the principal
office or applicable lending office of such Lender is located or under the laws
of any political subdivision or taxing authority of any such jurisdiction

                                      16.
<PAGE>

in which the principal office or applicable lending office of such Lender is
located and for any withholding of taxes as such Lender shall determine are
payable by, or withheld from, such Lender, in each case in respect of such
amounts so paid to or on behalf of such Lender pursuant to the foregoing and in
respect of any amounts paid to or on behalf of such Lender pursuant to this
sentence. Borrower will furnish to Administrative Agent within 45 days (or as
soon thereafter as available) after the date the payment of any Taxes or Other
Taxes is due pursuant to applicable law certified copies of receipts evidencing
such payment by Borrower. Borrower agrees to indemnify and hold harmless each
Lender, and immediately reimburse such Lender upon its written request, for the
amount of any Taxes or Other Taxes so levied or imposed and paid by such Lender.

              (b) If Borrower pays any additional amount under this SECTION 3.4
to a Lender and such Lender, in such Lender's sole and absolute determination,
has received or realized in connection therewith any refund or any reduction of,
or credit against, its tax liabilities in or with respect to the taxable year in
which the additional amount is paid, such Lender shall pay to Borrower an amount
equal to the net benefit, after tax, which was obtained by the Lender in such
year as a consequence of such refund, reduction or credit. Such amount shall be
paid as soon as practicable after receipt or realization by such Lender of such
refund, reduction or credit.

              (c) Each Lender shall use reasonable efforts (consistent with
legal and regulatory restrictions and subject to overall policy considerations
of such Lender) to file any certificate or document or to furnish any
information as reasonably requested by Borrower pursuant to any applicable
treaty, law or regulation, if the making of such filing or the furnishing of
such information would avoid the need for or reduce the amount of any amounts
payable by Borrower under SECTION 3.4(a); provided, however, that the failure of
any Lender to use such efforts shall not in any way diminish the obligations of
Borrower under this SECTION 3.4 or otherwise under this Agreement.

              (d) Notwithstanding anything in this SECTION 3.4 to the contrary,
Borrower shall have no obligation to make any payment of Taxes pursuant to this
SECTION 3.4 to any Lender, other than QUALCOMM, in excess of such Gross Up
Amounts which would be applicable in the case of payments to a Registered
Financial Institution.

stated, and all Liens of any nature given or agreed to be given as security
therefor are correctly described or indicated in such Schedule.

with the transactions contemplated hereby or by the other Credit Documents taken

made, not misleading. As of the Effective Date, there is no fact known to

ordinances or rules applicable to them, violation of which would be reasonably
likely to have a Material Adverse Effect.

              (a) EMPLOYEE BENEFITS:

                     (i) Each employee benefit plan, if any, has been
maintained, operated and administered in accordance with its terms and with
applicable law, and all notices, filings and disclosures required by terms or
law have been timely made as of the date hereof, except when the failure to
maintain, operate, or administer, or to notify, file or disclose, could not
reasonably be expected to have a Material Adverse Effect. No proceeding with
respect to the administration or the investment of the assets of any employee
benefit plan (other than routine claims for benefits) that could reasonably be
expected to have a Material Adverse Effect or create any material Lien is
pending or threatened.

                     (ii) All obligations of the Borrower Group for payments
with respect to any and all mandatory and additional employee benefit plans
including, but not limited to, all IMSS, INFONAVIT, accrued payroll and payroll
taxes payments for their respective employees have been timely paid and properly
reported in the financial statements required to be delivered under SECTION
6.1(a) AND (b) in accordance with GAAP except where the failure to make such
payments could not reasonably be expected to have a Material Adverse Effect or
create any material Lien.

                     (iii) The Borrower Group has no liability for retiree
benefits.

              (b) EMPLOYMENT PRACTICES:

rules and regulations with respect to employment practices including, but not
limited to, applicable health and safety regulations and there is no charge or
complaint alleging such a violation against the Borrower pending or threatened,
or before any federal or local labor board, tribunal or CONSAR; and

<PAGE>

              (c) there is no labor strike, request for representation, slowdown
or stoppage actually pending or, to the knowledge of the Borrower Group,

reports, statements, provider agreements, benefit plan descriptions, payor
agreements, beneficiary materials and other documents (including, without
limitation, those related to employee benefit plans) required to be filed by it
with any Governmental Entities, including without limitation state and federal
insurance and health regulatory authorities except where the failure to file
could not reasonably be expected to have a Material Adverse Effect or create a
material Lien.

       5.22 SOVEREIGN IMMUNITY. This Agreement, the other Credit Documents and
the Loans are of a commercial rather than the public or governmental nature and
Borrower is not entitled to claim immunity from legal proceedings with respect
to itself or any of its properties or assets on any grounds of sovereignty or
otherwise under any Mexican law. To the extent that Borrower or any of its
properties or assets has or hereafter may acquire any rights to immunity from
setoff, legal proceedings, attachment prior to judgment, other attachment or
execution of judgment of any grounds of sovereignty or otherwise (whether under
the laws of Mexico or any other jurisdiction), to the extent permitted by
applicable law Borrower hereby irrevocably waives such right to immunity for
itself and its properties and assets in respect of its obligations arising under
or relating to this Agreement or any other Credit Document.

              (c) The words "hereof," "herein" and "hereunder" and words of
similar import when used in this Agreement shall refer to this Agreement as a
whole and not to any particular provision of this Agreement. Section,
subsection, schedule and exhibit references are to this Agreement unless
otherwise specified. The term "including" is not limiting and means "including,
without limitation," and "including, but not limited to."

              (d) Whenever, from the context it appears appropriate, each term
stated in either the singular or the plural shall include the singular or the
plural, and pronouns stated in the masculine, feminine or neuter gender shall
include the masculine, feminine and neuter.

              (e) Unless otherwise specified herein, all accounting terms used
herein shall be interpreted, and all Financial Statements required to be
delivered hereunder shall be prepared

in accordance with GAAP. If any changes in GAAP from those used in the
preparation of the financial statements referred to in SECTION 5.8 hereof ("GAAP
Changes") hereafter occasioned by the promulgation of rules, regulations,
pronouncements and opinions by or required by the Financial Accounting Standards
Board of the American Institute of Certified Public Accountants or Mexico or
international equivalent thereof (or successors thereto or agencies with similar
functions) result in a change in the method of calculation of any of the
financial covenants, standards or other terms or conditions found in this
Agreement, the parties hereto agree to enter into negotiations to amend such
provisions so as to reflect equitably such GAAP Changes with the desired result
that the criteria for evaluating the financial condition and performance of any
Guarantor or Borrower and their Subsidiaries shall be the same after such GAAP
Changes as if such GAAP Changes had not been made.

SECTION 10. ADMINISTRATIVE AGENT.

       10.1 APPOINTMENT OF QUALCOMM AS ADMINISTRATIVE AGENT. Lenders hereby
designate and appoint QUALCOMM. as Administrative Agent to act in an
administrative function as specified under this Agreement and the other Credit
Documents and irrevocably authorizes Administrative Agent to take such action on
its behalf under and subject to the provisions of this Agreement and each other
Credit Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Credit
Document, together with such other powers, in the judgment of Administrative
Agent, as are reasonably incidental thereto. Notwithstanding any provision to
the contrary elsewhere in this Agreement or any other Credit Document,
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein or therein, or any fiduciary relationship with any
Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Credit
Document or otherwise exist against Administrative Agent.

       10.2 DELEGATION OF DUTIES BY ADMINISTRATIVE AGENT. Administrative Agent
may execute any of its duties under this Agreement by or through the
Administrative Agents, employees or attorneys-in-fact and shall be entitled to
advice of counsel concerning all matters pertaining to such duties.
Administrative Agent shall not be responsible for the negligence or misconduct
of any Administrative Agent or attorney-in-fact that it selects with reasonable
care.

       10.3 LIABILITY OF ADMINISTRATIVE AGENT. None of Administrative
Agent-Related Persons (defined below) shall (a) be liable for any action taken
or omitted to be taken by any of them under or in connection with this Agreement
or any other Credit Document (except for its own gross negligence or willful
misconduct), or (b) be responsible in any manner to any of the Lenders for any
recital, statement, representation or warranty made by Borrower or any Affiliate
of Borrower, or any officer thereof, contained in this Agreement or in any other
Credit Document, or in any certificate, report, statement or other document
referred to or provided for in, or received by Administrative Agent under or in
connection with, this Agreement or any other Credit Document, or for the value
of any Collateral or the validity, priority, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any Credit Document, or for
any failure of Borrower or any other party to any Credit Document to perform its
obligations hereunder or thereunder. No Administrative Agent-Related Person
shall be under any obligation to any Lender to ascertain or to inquire as to the
observance or performance of any of the

                                      59.
<PAGE>

agreements contained in, or conditions of, this Agreement or any other Credit
Document, or to inspect the Properties, books or records of Borrower or any of
Borrower's Affiliates. "Administrative Agent-Related Persons" shall mean
Administrative Agent and any successor Administrative Agent, together with their
respective Affiliates, and the employees, agents and attorneys-in-fact of such
persons.

       10.4 RELIANCE BY ADMINISTRATIVE AGENT.

              (a) Administrative Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to Borrower),
independent accountants and other experts selected by Administrative Agent.
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Credit Document unless it shall first
receive such advice or concurrence of Requisite Lenders as it deems appropriate
and indemnification for all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action, provided, however, that
Administrative Agent shall be justified in refusing to take action if such
action is in violation of law or the terms of this Agreement or any other Credit
Document, based on the advise of Administrative Agent's legal counsel.
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement or any other Credit Document in
accordance with a request or consent of Requisite Lenders and such request and
any action taken or failure to act pursuant thereto shall be binding upon all of
Lenders.

              (b) For purposes of determining compliance with the conditions
precedent specified in SECTION 4, each Lender that has executed this Agreement
or shall hereafter execute and deliver an Assignment Agreement shall be deemed
to have consented to, approved or accepted or to be satisfied with each document
or other matter either sent by Administrative Agent to such Lender for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to such Lender, unless an officer
of Administrative Agent responsible for the transactions contemplated by the
Credit Documents shall have received notice from such Lender prior to the
initial borrowing specifying its objection thereto and either such objection
shall not have been withdrawn by notice to Administrative Agent to that effect
or such Lender shall not have made available to Administrative Agent its ratable
portion of such borrowing.

       10.5 NOTICE OF DEFAULT. Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default, except
with respect to defaults in the payment of principal, interest and fees required
to be paid to Administrative Agent on behalf and for the benefit of Lenders,
unless Administrative Agent shall have received written notice from a Lender or
Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default." In the event that
Administrative Agent receives such a notice, Administrative Agent shall give
notice thereof to each Lender. Administrative Agent shall take such action with
respect to such Default or Event of Default as shall be requested by Requisite
Lenders in accordance with SECTION 8; provided, however, that unless and until
Administrative Agent shall have received any such request, Administrative

                                      60.
<PAGE>

Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem in the best interest of Lenders.

       10.6 NON-RELIANCE BY LENDERS. Each Lender expressly acknowledges that
none of Administrative Agent-Related Persons has made any representation or
warranty to it and that no act by Administrative Agent hereafter taken,
including any review of the affairs of Borrower, shall be deemed to constitute
any representation or warranty by Administrative Agent to such Lender. Each
Lender confirms to Administrative Agent that it has not relied, and will not
rely hereafter, on Administrative Agent to check or inquire on such Lender's
behalf into the adequacy, accuracy or completeness of any information provided
by Borrower or any other Person under or in connection with the Credit Documents
or the transactions herein contemplated (whether or not the information has been
or is hereafter distributed to such Lender by Administrative Agent). Each Lender
represents to Administrative Agent that it has, independently and without
reliance upon Administrative Agent and based on such documents and information
as it has deemed appropriate, made its own appraisal of and investigation into
the business, prospects, operations, property, financial and other condition and
creditworthiness of Borrower, and all applicable regulatory laws relating to the
transactions contemplated thereby, and made its own decision to enter into this
Agreement and the other Credit Documents and extend credit to Borrower under and
pursuant to this Agreement. Each Lender also represents that it will,
independently and without reliance upon Administrative Agent and based on such
documents and appraisals and decisions in taking or not taking action under this
Agreement and the other Credit Documents, and to make such investigations as it
deems necessary to inform itself as to the business, prospects, operations,
property, financial and other condition and creditworthiness of Borrower. Except
for notices, reports and other documents expressly herein required to be
furnished to Lenders by Administrative Agent, Administrative Agent shall not
have any duty or responsibility to provide to any Lender any credit or other
information concerning the business, prospects, operations, Property, financial
and other condition or creditworthiness of Borrower which may come into the
possession of any Administrative Agent-Related Persons. Administrative Agent
shall not be responsible to any Lender for the execution, effectiveness,
priority, genuineness, validity, enforceability, collectability or sufficiency
of this Agreement the Credit Documents or for any representations or warranties,
recitals or statements made herein or therein or made in any written or oral
statements, or in any financial or other statements, instruments, reports or
certificates or any other documents furnished or made available by
Administrative Agent to Lenders or by or on behalf of Borrower to Administrative
Agent or any Lender in connection with the Credit Documents or the transactions
contemplated thereby or for the financial condition or business affairs of
Borrower or any Person liable for payment of the Obligations, nor shall
Administrative Agent be required to ascertain or inquire as to the performance
or observance of any of the terms, conditions, provisions, covenants or
agreements contained in any of the Credit Documents or as to the use of proceeds
of the Loans or as to the existence or possible existence of any Default or
Event of Default.

       10.7 INDEMNIFICATION. Whether or not the transactions contemplated hereby
are consummated, Lenders shall indemnify upon demand Administrative
Agent-Related Persons (to the extent not reimbursed by or on behalf of Borrower
and without limiting the obligation of Borrower to do so) ratably from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses and disbursements of any kind
whatsoever which may at any time (including at any time following the repayment
of the Loans or the

                                      61.
<PAGE>

termination or the resignation of the related Administrative Agent) be imposed
on, incurred by or asserted against any such Person in any way relating to or
arising out of this Agreement or any of the other Credit Documents or the
transactions contemplated hereby or thereby or any action taken or omitted by
any such Person under or in connection with any of the foregoing; provided,
however, that no Lender shall be liable for the payment to Administrative
Agent-Related Persons of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from such Person's gross negligence or willful misconduct. Without
limitation of the foregoing, each Lender shall reimburse Administrative Agent
upon demand for its ratable share of any costs or other out-of-pocket expenses
(including reasonable attorneys' expenses and disbursements) incurred by
Administrative Agent in connection with the preparation, execution,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement or any other Credit Document to
the extent that Administrative Agent has not previously been reimbursed for such
expenses by or on behalf of Borrower. Without limiting the generality of the
foregoing, if any Governmental Entity or any Administrative Agent did not
properly withhold tax from amounts paid to or for the account of any Lender
(because the appropriate form was not delivered, was not properly executed, or
because such Lender failed to notify Administrative Agent of a change in
circumstances which rendered the exemption from, or reduction of, withholding
tax ineffective, or for any other reason), such Lender shall indemnify
Administrative Agent fully for all amounts paid, directly or indirectly, by
Administrative Agent as tax or otherwise, including penalties and interest, and
including any taxes imposed by any jurisdiction on the amounts payable to
Administrative Agent under this SECTION 10.7, together with all costs and
expenses (including reasonable attorneys' expenses and disbursements). The
obligations of Lenders in this SECTION 10.7 shall survive the repayment of all
Obligations and the termination of the Credit Documents.

       10.8 SUCCESSOR ADMINISTRATIVE AGENT. Administrative Agent may, and at the
request of Requisite Lenders shall, resign as Administrative Agent upon 30 days'
notice to Lenders. If Administrative Agent shall resign as Administrative Agent
under this Agreement and the other Credit Documents, then Requisite Lenders
shall appoint from among Lenders a successor Administrative Agent for Lenders.
If no successor Administrative Agent is appointed prior to the effective date of
the resignation of Administrative Agent, Administrative Agent may appoint, after
consulting with Lenders and Borrower, a successor Administrative Agent from
among Lenders. Upon the acceptance of its appointment as successor
Administrative Agent hereunder and under the other Credit Documents, such
successor Administrative Agent shall succeed to the rights, powers and duties of
Administrative Agent, the term "Administrative Agent" shall mean such successor
Administrative Agent effective upon its appointment, and the former
Administrative Agent's appointment, rights, powers and duties as Administrative
Agent shall be terminated. After any retiring Administrative Agent's resignation
as Administrative Agent, the provisions of this SECTION 10 and SECTION 11.1
shall continue to inure to its benefit as to actions taken or omitted to be
taken by it while it was Administrative Agent under this Agreement and the other
Credit Documents.

                                      62.
<PAGE>

              (a) Borrower agrees to: (i) pay the costs and expense of
Administrative Agent and each Lender in connection with the enforcement of the
Credit Documents; and (ii) pay and hold each of the Lenders harmless from and
against any and all present and future stamp and other similar taxes with
respect to the foregoing matters and save each of the Lenders harmless from and
against any and all liabilities with respect to or resulting from any delay or
omission (other than to the extent attributable to such Lender) to pay such
taxes.

              (b) Borrower agrees to indemnify, save, and hold harmless
Administrative Agent, Lenders and their directors, officers, agents, attorneys
and employees (collectively, the "indemnitees") from and against: (i) any and
all claims, demands, actions, or causes of action that are asserted against any
indemnitee by any Person if the claim, demand, action, or cause of action arises
out of or relates to a claim, demand, action, or cause of action that the Person
asserts or may assert against Borrower, or any officer, director or shareholder
of Borrower in their capacity as such, (ii) any and all claims, demands, actions
or causes of action that are asserted against any indemnitee (other than by
Borrower or by another indemnitee) if the claim, demand, action or cause of
action arises out of or relates to the Loans, the use of proceeds of any Loans,
or the relationship of Borrower and Lenders under this Agreement or any
transaction contemplated pursuant to this Agreement, (iii) any administrative or
investigative proceeding by any governmental agency arising out of or related to
a claim, demand, action or cause of action described in clauses (i) or (ii)
above; and (iv) any and all liabilities, losses, costs, or expenses (including
outside attorneys' fees, in-house counsel fees and disbursements) that any
indemnitee suffers or incurs as a result of any of the foregoing; provided, that
Borrower shall have no obligation under this SECTION 11.1 to any Lender or
Administrative Agent with respect to any of the foregoing arising out of the
gross negligence or willful misconduct of such Lender or Administrative Agent.

       11.2 RIGHT OF SETOFF. In addition to any rights now or hereafter granted
under applicable law or otherwise, and not by way of limitation of any such
rights, if an Event of Default then exists, each Lender is hereby authorized at
any time or from time to time, without presentment, demand, protest or other
notice of any kind to any Credit Party or to any other Person, any such notice
being hereby expressly waived, to set off and to appropriate and apply any and
all deposits (general or special but other than payroll accounts) and any other
Indebtedness at any time held or owing by such Lender (including, without
limitation, by branches and agencies of such Lender wherever located) to or for
the credit or the account of any Credit Party against and on account of the
Obligations and liabilities of such Credit Party to such Lender under this
Agreement or under any of the other Credit Documents, including, without
limitation, all interests in Obligations of such Credit Party purchased by such
Lender pursuant to SECTION 11.6(b), irrespective of whether or not such Lender
shall have made any demand hereunder and although said Obligations, liabilities
or claims, or any of them, shall be contingent or unmatured.

       11.3 NOTICES. Except as otherwise expressly provided herein, all notices
and other communications provided for hereunder shall be in writing (including
telex, telecopier, facsimile

                                      63.
<PAGE>

or electronic mail) and mailed, telexed, telecopied, faxed, electronic mailed or
delivered, if to a Credit Party, at the address specified opposite its signature
below or in the other relevant Credit Documents, as the case may be; if to any
Lender, at its address specified for such Lender on the signature pages hereto;
or, at such other address as shall be designated by any party in a written
notice to the other parties hereto. All such notices and communications shall be
mailed, telexed, telecopied, or electronic mailed or sent by overnight courier,
and shall be effective when received.

       11.4 BENEFIT OF AGREEMENT.

              (a) This Agreement shall be binding upon and inure to the benefit
of and be enforceable by the respective successors and assigns of the parties
hereto, provided that Borrower may not assign or transfer any of its rights or
obligations hereunder without the prior written consent of the Lenders. Each
Lender may at any time grant participations in any of its rights hereunder or
under any of the Notes or Pagares to an Eligible Transferee, provided that in
the case of any such participation, the participant shall not have any rights
under this Agreement or any of the other Credit Documents (the participant's
rights against such Lender in respect of such participation to be those set
forth in the agreement executed by such Lender in favor of the participant
relating thereto) and all amounts payable by Borrower hereunder shall be
determined as if such Lender had not sold such participation, except that the
participant shall be entitled to the benefits of SECTIONS 1.9 and 3.4 of this
Agreement to the extent that such Lender would be entitled to such benefits if
the participation had not been entered into or sold, and, provided further that
no Lender shall transfer, grant or assign any participation under which the
participant shall have rights to approve any amendment to or waiver of this
Agreement or any other Credit Document except to the extent such amendment or
waiver would (i) extend the final scheduled maturity of any Loan in which such
participant is participating (it being understood that any waiver of the
application of any prepayment or the method of any application of any prepayment
to, the amortization of the Loans shall not constitute an extension of the final
maturity date), or reduce the rate or extend the time of payment of interest or
Fees thereon (except in connection with a waiver of the applicability of any
post-default increase in interest rates), or reduce the principal amount
thereof, or increase such participant's participating interest in any Commitment
over the amount thereof then in effect (it being understood that a waiver of any
Default or Event of Default or of a mandatory reduction in the Commitments, or a
mandatory prepayment, shall not constitute a change in the terms of any
Commitment), (ii) release all or substantially all of the Collateral or (iii)
consent to the assignment or transfer by Borrower of any of its rights and
obligations under this Agreement.

              (b) Notwithstanding the foregoing and subject to the limitations
on Syndications set forth in SECTION 1.12, (x) any Lender may assign all or a
portion of its outstanding Loans and/or Commitments and its rights and
obligations hereunder to one or more other Lenders, and (y) with the consent of
QUALCOMM, Administrative Agent and Borrower (which consents shall not be
unreasonably withheld) any Lender may assign all or a portion of its outstanding
Loans and/or Commitments and its rights and obligations hereunder to one or more
Eligible Transferees. No assignment pursuant to the immediately preceding
sentence shall to the extent such assignment represents an assignment to an
institution other than one or more Lenders hereunder, be in an aggregate amount
less than $5,000,000 (unless such assignee has agreed to purchase assignments of
interests under this Agreement is a series of transactions which, in the

                                      64.
<PAGE>

aggregate, will total an original amount not less than $5,000,000. If any Lender
so sells or assigns all or a part of its rights hereunder, any reference in this
Agreement to such assigning Lender shall thereafter refer to such Lender and to
the respective assignee to the extent of their respective interests and the
respective assignee shall have, to the extent of such assignment (unless
otherwise provided therein), the same rights and benefits as it would if it were
such assigning Lender. Each assignment pursuant to this SECTION 11.4(b) shall be
effected by the assigning Lender and the assignee Lender executing an Assignment
Agreement and giving Administrative Agent written notice thereof. At the time of
any such assignment, (i) either the assigning or the assignee Lender shall pay
to Administrative Agent a nonrefundable assignment fee of $1,500, (ii) SCHEDULE
1.0 shall be deemed to be amended to reflect the Commitments of the respective
assignee (which shall result in a direct reduction to the Commitments of the
assigning Lender) and of the other Lenders, and (iii) Borrower will, if
requested, issue new Notes or Pagares to the respective assignee and to the
assigning Lender. To the extent that an assignment pursuant to this SECTION
11.4(b) would, at the time of such assignment, result in increased costs under
SECTION 1.9 or 3.4 from those being charged by the respective assigning Lender
prior to such assignment, then Borrower shall not be obligated to pay such
increased costs (although Borrower shall be obligated to pay any other increased
costs of the type described above resulting from changes after the date of the
respective assignment). Each Lender and Borrower agree to execute such documents
(including without limitation amendments to this Agreement and the other Credit
Documents) as shall be necessary to effect the foregoing. Nothing in this clause
(b) shall prevent or prohibit any Lender from pledging its Notes or Pagares or
Loans to a Federal Reserve Bank in support of borrowings made by such Lender
from such Federal Reserve Bank.

              (c) Notwithstanding any other provisions of this SECTION 11.4, no
transfer or assignment of the interests or obligations of any Lender hereunder
or any grant of participation therein shall be permitted if such transfer,
assignment or grant would require Borrower to file a registration statement with
the SEC or to qualify the Loans under the "Blue Sky" laws of any State.

              (d) Each Lender initially party to this Agreement hereby
represents, and each Person that became a Lender pursuant to an assignment
permitted by this SECTION 11.4 will, upon its becoming party to this Agreement,
represent that it is an Eligible Transferee which makes loans in the ordinary
course of its business and that it will make or acquire Loans for its own
account in the ordinary course of such business, provided that subject to the
preceding clauses (a) and (b), the disposition of any promissory notes or other
evidences of or interests in Indebtedness held by such Lender shall at all times
be within its exclusive control.

       11.5 NO WAIVER; REMEDIES CUMULATIVE. No failure or delay on the part of
Administrative Agent or any Lender in exercising any right, power or privilege
hereunder or under any other Credit Document and no course of dealing between
any Credit Party and Administrative Agent or any Lender shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder or under any other Credit Document preclude any other or
further exercise thereof or the exercise of any other right, power or privilege
hereunder or thereunder. The rights and remedies herein expressly provided are
cumulative and not exclusive of any rights or remedies which Administrative
Agent or any Lender would otherwise have. No notice to or demand on any Credit
Party in any case shall

                                      65.
<PAGE>

entitle any Credit Party to any other or further notice or demand in similar or
other circumstances or constitute a waiver of the rights of Administrative Agent
or the Lenders to any other or further action in any circumstances without
notice or demand.

       11.6 PAYMENTS PRO RATA.

              (a) Administrative Agent agrees that promptly after its receipt of
each payment from or on behalf of any Credit Party in respect of any Obligations
of such Credit Party, it shall distribute such payment to the Lenders (other
than any Lender that has expressly waived its right to receive its pro rata
share thereof) pro rata based upon their respective shares, if any, of the
Obligations with respect to which such payment was received.

              (b) Each of the Lenders agrees that, if it should receive any
amount hereunder (whether by voluntary payment, by realization upon security, by
the exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Credit Documents, or
otherwise) which is applicable to the payment of the principal of, or interest
on, the Loans or Fees, of a sum which with respect to the related sum or sums
received by other Lenders is in a greater proportion than the total of such
Obligation then owed and due to such Lender bears to the total of such
Obligation then owed and due to all of the Lenders immediately prior to such
receipt, then such Lender receiving such excess payment shall purchase for cash
without recourse or warranty from the other Lenders an interest in the
Obligations of the respective Credit Party to such Lenders in such amount as
shall result in a proportional participation by all of the Lenders in such
amount, provided that if all or any portion of such excess amount is thereafter
recovered from such Lender, such purchase shall be rescinded and the purchase
price restored to the extent of such recovery, but without interest.

       11.7 CALCULATIONS; COMPUTATIONS.

              (a) The financial statements to be furnished to the Lenders
pursuant hereto shall be made and prepared in accordance with GAAP consistently
applied throughout the periods involved (except as set forth in the notes
thereto or as otherwise disclosed in writing by Borrower to the Lenders),
provided that if at any time such computations utilize accounting principles
different from those utilized in the financial statements furnished to the
Lenders, such financial statements shall be accompanied by reconciliation
worksheets.

              (b) All computations of interest and Fees hereunder shall be made
on the actual number of days elapsed over a year of 360 days (365 or 366 days,
as the case may be, in the case of Fees and Base Rate Loans).

       11.8 GOVERNING LAW; SUBMISSION TO JURISDICTION; VENUE; WAIVER OF JURY
TRIAL.

              (a) This Agreement shall be governed by, and construed in
accordance with, the law of the State of New York, United States, without
reference to principles of conflicts of law (other than Section 5-1401 of the
General Obligations Laws of the State of New York); provided, however, that in
connection with any legal action or proceeding (other than an action to enforce
a judgment obtained in another jurisdiction) brought in respect to this
Agreement in the courts of Mexico or any political subdivision thereof, this
Agreement shall be deemed to be

                                      66.
<PAGE>

an instrument made under the laws of Mexico and for such purposes shall be
governed by, and construed in accordance with, the laws of the Federal District
of Mexico.

              (b) Each party hereto hereby agrees that any suit, action or
proceeding with respect to this Agreement or any judgment entered by any court
in respect thereof may be brought in the United States of America District Court
for the Southern District of New York, in the Supreme Court of the State of New
York sitting in New York County (including its Appellate Division), or in any
other appellate court in the State of New York or the competent courts of the
Federal District of Mexico, as the party commencing such suit, action or
proceeding may elect in its sole discretion; and each party hereto hereby
irrevocably submits to the jurisdiction of such courts for the purpose of any
such suit, action, proceeding or judgment. Each party hereto further submits,
for the purpose of any such suit, action, proceeding or judgment brought or
rendered against it, to the appropriate courts of the jurisdiction of its
domicile. Borrower hereby waives any rights to a specific jurisdiction it may
have by virtue of its present or any future domicile, or otherwise.

              (c) The Borrower hereby agrees that service of all writs, process
and summonses in any such suit, action or proceeding brought in the State of New
York may be made upon CT Corporation System, presently located at 1633 Broadway,
New York, New York 10019, U.S.A. (the "Process Agent"), and the Borrower hereby
confirms and agrees that the Process Agent has been duly and irrevocably
appointed as its agent and true and lawful attorney-in-fact in its name, place
and stead to accept such service of any and all such writs, process and
summonses, and agrees that the failure of the Process Agent to give any notice
of any such service of process to the Borrower shall not impair or affect the
validity of such service or of any judgment based thereon. The Borrower hereby
further irrevocably consents to the service of process in any suit, action or
proceeding in said courts by the mailing thereof by the Lender by registered or
certified mail, postage prepaid, at its address set forth beneath its signature
hereto.

              (d) Nothing herein shall in any way be deemed to limit the ability
of the Lenders to serve any such writs, process or summonses in any other manner
permitted by applicable law or to obtain jurisdiction over Borrower in such
other jurisdictions, and in such manner, as may be permitted by applicable law.

              (e) Borrower hereby irrevocably waives any objection that it may
now or hereafter have to the laying of the venue of any suit, action or
proceeding arising out of or relating to this Agreement or any other Credit
Document brought in the Supreme Court of the State of New York, County of New
York, or in the United States of America District Court for the Southern
District of New York or the competent courts of the Federal District of Mexico,
and hereby further irrevocably waives any claim that any such suit, action or
proceeding brought in any such court has been brought in an inconvenient forum.

              (f) The Borrower hereby agrees to cause the Process Agent to
execute and deliver to the Lender a letter from the Process Agent to the Lender
confirming Process Agent's acceptance of the appointment by Borrower prescribed
in SECTION 11.8(c).

       11.9 COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and

                                      67.
<PAGE>

delivered shall be an original, but all of which shall together constitute one
and the same instrument. A set of counterparts executed by all the parties
hereto shall be lodged with Borrower and Administrative Agent.

       11.10 EFFECTIVENESS. This Agreement shall become effective on the date
(the "Effective Date") on which Borrower and each of the Lenders shall have
signed a copy hereof (whether the same or different copies) and shall have
delivered the same to Administrative Agent at its Notice Office or, in the case
of the Lenders, shall have given to Administrative Agent telephonic (confirmed
in writing), written telex or facsimile transmission notice (actually received)
at such office that the same has been signed and sent to it.

       11.11 HEADINGS DESCRIPTIVE. The headings of the several sections and
subsections of this Agreement are inserted for convenience only and shall not in
any way affect the meaning or construction of any provision of this Agreement.

       11.12 AMENDMENT OR WAIVER. Neither this Agreement nor any other Credit
Document nor any terms hereof or thereof may be changed, waived, discharged or
terminated unless such change, waiver, discharge or termination is in writing
signed by the respective Credit Parties party thereto and Required Lenders,
provided that no such change, waiver, discharge or termination shall, without
the consent of each Lender directly affected thereby, (i) extend the final
scheduled maturity date of any Facility or any Note or Pagare, it being
understood that any waiver of any prepayment of, or the method of application of
any prepayment to the amortization of, the Loans shall not constitute any such
extension, or reduce the rate or extend the time of payment of interest (other
than as a result of waiving the applicability of any post-default increase in
interest rates) or Fees, or reduce the principal amount thereof, or increase the
Commitment of any Lender over the amount thereof then in effect (it being
understood that a waiver of any Default or Event of Default or of a mandatory
reduction in the Commitments shall not constitute a change in the terms of any
Commitment of any Lender), (ii) amend, modify or waive any provision of this
SECTION 11.12, (iii) reduce the percentage specified in, or (except to give
effect to any additional facilities hereunder) otherwise modify, the definition
of Required Lenders, (iv) consent to the assignment or transfer by Borrower of
any of its rights and obligations under this Agreement, (v) establish any new
obligations for any Lender or (vi) release all or substantially all of the
Collateral; provided that no such change, waiver, discharge or termination
shall, without the consent of Administrative Agent, amend any provision of
SECTION 10.

       11.13 SURVIVAL. All indemnities set forth herein including, without
limitation, in SECTION 1.9, 1.10, 3.4, 10.6 or 11.1 shall survive the execution
and delivery of this Agreement and the making and repayment of the Loans.

       11.14 DOMICILE OF LOANS. Each Lender may transfer and carry its Loans at,
to or for the account of any branch office, subsidiary or affiliate of such
Lender, provided that Borrower shall not be responsible for costs arising or
reimbursable under SECTION 1.9 or 3.4 resulting from any such transfer (other
than a transfer pursuant to SECTION 1.11) to the extent not otherwise applicable
to such Lender prior to such transfer.

                                      68.

       11.15 CONFIDENTIALITY. Subject to SECTION 11.4, the Lenders shall hold
all nonpublic information obtained pursuant to the requirements of this
Agreement which has been identified as such by Borrower in accordance with its
customary procedure for handling confidential information of this nature and in
accordance with safe and sound banking practices and in any event may make
disclosure to its Affiliates, employees, auditors, advisors, or counsel or as
reasonably required by any bona fide transferee or participant in connection
with the contemplated transfer of any Loans or participation therein (so long as
such transferee or participant agrees to be bound by the provisions of this
SECTION 11.15) or as required or requested by any governmental agency or
representative thereof or pursuant to legal process, provided that, unless
specifically prohibited by applicable law or court order, each Lender shall
notify Borrower of any request by any governmental agency or representative
thereof (other than any such request in connection with an examination of the
financial condition of such Lender by such governmental agency) for disclosure
of any such nonpublic information prior to disclosure of such information, and
provided further that in no event shall any Lender be obligated or required to
return any materials furnished by any Credit Party.

       11.16 LENDER REGISTER. Borrower hereby designates Administrative Agent to
serve as its agent, solely for purposes of this SECTION 11.16, to maintain a
register (the "Lender Register") on which it will record the Commitments from
time to time of each of the Lenders, the Loans made by each of the Lenders and
each repayment in respect of the principal amount of the Loans of each Lender.
Failure to make any such recordation, or any error in such recordation, shall
not affect Borrower's obligations in respect of such Loans. With respect to any
Lender, the transfer of the Commitments of such Lender and the rights to the
principal of, and interest on, any Loan made pursuant to such Commitments shall
not be effective until such transfer is recorded on the Lender Register
maintained by Administrative Agent and prior to such recordation all amounts
owing to the transferor with respect to such Commitments and Loans shall remain
owing to the transferor. The registration of assignment or transfer of all or
part of any Commitments and Loans shall be recorded by Administrative Agent on
the Lender Register only upon the acceptance by Administrative Agent of a
properly executed and delivered Agreement pursuant to SECTION 11.4(b). Borrower
agrees to indemnify Administrative Agent from and against any and all losses,
claims, damages and liabilities of whatsoever nature which may be imposed on,
asserted against or incurred by Administrative Agent in performing its duties
under this SECTION 11.16 other than those resulting from Administrative Agent's
willful misconduct or gross negligence.

       11.17 JUDGMENT CURRENCY. Borrower agrees to indemnify QUALCOMM against
any loss incurred by it as a result of any judgment or order being given or made
for the payment of any amount due under any Pagare which is expressed and paid
in a currency (the "Judgment Currency") other than the currency in which such
amount was to be paid (the "Obligation Currency") and as a result of any
variation between (i) the rate of exchange at which the Obligation Currency
amount is converted into Judgment Currency for the purposes of such judgment or
order, and (ii) the rate of exchange at which QUALCOMM is able to purchase the
Obligation Currency with the amount of judgment currency actually received by
QUALCOMM. The foregoing indemnity shall constitute a separate and independent
obligation of Borrower and shall continue in full force and effect
notwithstanding any such judgment or order as aforesaid. The term "rate of
exchange" shall include any premiums and costs of exchange payable in connection
with the purchase of, or conversions into, the relevant currency.

herewith;

        NOW, THEREFORE, IT IS AGREED:

SECTION 1. AMOUNT AND TERMS OF CREDIT.

        1.1 COMMITMENT. Subject to and upon the terms and conditions, and
subject to the limitations, herein set forth, each Lender severally agrees to
make Loans to Borrower, which Loans shall be drawn, to the extent such Lender
has a commitment under such Facility, under Facility-1, Facility-2 and the VAT
Facility, as set forth below:

                (a) Loans under Facility-1 (each, together with Facility-1 Loans
deemed made pursuant to SECTION 1.5(b), a "Facility-1 Loan" and, collectively,
the "Facility-1 Loans") shall (i) be made from time to time on a Business Day
during the Facility-1 Availability Period, (ii) constitute Tranche A Loans if

constitute Tranche B Loans if such Loans are not Tranche A Loans or Tranche C
Loans, (v) not exceed in aggregate principal amount for any Lender with respect
to any incurrence thereof the Facility-1 Commitment of such Lender as in effect
on the date of such incurrence and (vi) to the extent made in any calendar year,
not exceed in the aggregate the sum of the Base Financing Percentage plus the
Contingent Financing Percentage, if any, for such calendar year of QUALCOMM
Costs required to be paid in such calendar year; provided that, with respect to
all of the foregoing, no Loans that are EXIM Qualified will be made under
Facility-1 after the Facility-1 EXIM Loans Closing Date. Once repaid, Facility-1
Loans may not be reborrowed.

                (b) Loans under Facility-2 (each a "Facility-2 Loan" and,
collectively, the "Facility-2 Loans") shall (i) be made from time to time on a
Business Day during the Facility-2 Availability Period, (ii) constitute (x)
Tranche A Loans if such Loans are EXIM Qualified and are made prior to the
Facility-2 Refinancing Date or (y) Tranche B if such Loans are not EXIM
Qualified or are made on and after the Facility-2 Refinancing Date, (iii) not
exceed in aggregate principal amount with respect to any incurrence thereof the
Facility-2 Commitment of such Lender as in effect on the date of such incurrence
and (iv) to the extent made in any calendar year, not exceed in the aggregate
the sum of the Base Financing Percentage plus the Contingent Financing
Percentage, if any, for such calendar year of QUALCOMM Costs required to be paid
in such calendar year; provided that, with respect to all of the foregoing, no
Loans that are EXIM Qualified will be made under Facility-2 after the Facility-2
EXIM Loans Closing Date. Once repaid, Facility-2 Loans may not be reborrowed.

                (c) Loans under the VAT Facility (each, a "VAT Loan" and,
collectively, the "VAT Loans") (i) shall, except for the Existing VAT Loans, be
made at any time and from time to time on a Business Day during the VAT Facility
Availability Period, (ii) may be repaid and reborrowed in accordance with the
provisions hereof and (iii) shall not exceed (inclusive of the

                                       2.
<PAGE>

Existing VAT Loans and giving effect to any incurrence) for any Lender in
aggregate principal amount at the time of the incurrence thereof the VAT Loan
Commitment of such Lender at such time.

                (d) Notwithstanding anything in this Agreement to the contrary,
no Lender shall be obligated to make any Loan, to the extent that the initial
aggregate principal amount of all Loans (other than Loans representing the
capitalization of interest pursuant to SECTION 1.8) made hereunder shall exceed
the Total Commitment.

                (e) Long-Term Loans which are incurred on or after the Original
Effective Date shall be allocated among Tranche A, Tranche B and Tranche C Loans
in the following priority:

        First, to Tranche A Loans to the extent of 85% of each Invoice for
        QUALCOMM Costs allocable to the sale of equipment and to the provision
        of services in the U.S.;

        Second, to Tranche C Loans to the extent of the availability thereof;
        and

        Third, to Tranche B Loans to the extent of the availability thereof;

        provided, however, that upon receiving confirmation satisfactory to
        QUALCOMM from the Export Import Bank of the U.S. that costs reflected in
        any Invoice are, or are not, EXIM Qualified, QUALCOMM may, but shall not
        be obligated to, redesignate Tranche A Loans, in whole or part, in order
        of priority according to availability, to be Tranche C Loans or Tranche
        B Loans and, upon written notice to Administrative Agent, with a copy
        thereof to Borrower, the interest accrued pursuant to each such
        redesignated Loan shall be retroactively adjusted from the date such
        redesignated Tranche A Loan was originally made and paid, or credited,
        as applicable, on the next succeeding Interest Payment Date; provided
        further, that if QUALCOMM shall arrange one or more EXIM Financings
        which are in the "best commercial interests" of Borrower as contemplated
        in SECTION 1.12 and Borrower shall not agree to such Refinancing, all
        Tranche A Loans shall be thereupon redesignated, in whole or part, in
        order of priority according to availability, to be Tranche C Loans or
        Tranche B Loans and, upon written notice to Administrative Agent, with a
        copy thereof to Borrower, the interest accrued pursuant to each such
        redesignated Loan shall be retroactively adjusted from the date such
        redesignated Tranche A Loan was originally made and paid, or credited,
        as applicable, on the next succeeding Interest Payment Date; provided,
        further, that if QUALCOMM provides notice that QUALCOMM has been advised
        by the Export Import Bank of the U.S. that EXIM Financings will for any
        reason not be available or, if available, are not available on terms
        determined in QUALCOMM's reasonable judgement to be commercially
        reasonable, in respect of any or all of the Tranche A Loans either
        outstanding or as permitted herein, together with such materials as
        shall reasonably evidence such position of the EXIM Bank of the U.S,
        then, for such period as EXIM Financings will be unavailable or are not
        available on commercially reasonable terms, all existing Tranche A Loans
        shall be redesignated, in whole or part, in order of priority according
        to availability, to be Tranche C Loans or Tranche B Loans, no further
        Tranche A Loans shall be made and, upon written notice to Administrative
        Agent, with a copy thereof to

                                       3.
<PAGE>

        Borrower, the interest accrued pursuant to each such redesignated Loan
        shall be retroactively adjusted from the date of such notice and paid,
        or credited, as applicable, on the next succeeding Interest Payment
        Date; provided, further, that with respect to Loans made under
        Facility-2, the foregoing references to Tranche C Loans, and designation
        and redesignation of Loans as Tranche C Loans shall be ignored.

        1.2 TYPES OF LONG-TERM LOANS. Each Long-Term Loan shall, in accordance
with the terms of this Agreement, be in the form of either a Base Rate Loan or a
Eurodollar Loan; provided, however, that, notwithstanding anything to the
contrary herein, each initial Borrowing of Long-Term Loans pursuant to SECTION
1.5(b) hereof shall be comprised solely of Base Rate Loans until the first
Business Day of the calendar month next succeeding the effective date of such
initial Borrowing of such Loans but may as of such Business Day be converted
into Eurodollar Loans and continued as provided in SECTION 1.3 hereof. At no
time may Borrower maintain Eurodollar Loans in more than six (6) separate
Interest Periods in respect of Facility-1 Loans and six (6) separate Interest
Periods in respect of Facility-2 Loans.

        1.3 CONVERSION AND CONTINUATION ELECTIONS. Borrower may, upon
irrevocable written notice to Administrative Agent, with reference to the
Long-Term Loans:

                (a) elect to convert on any Business Day, Base Rate Loans in an
amount equal to Two Million Five Hundred Thousand ($2,500,000) (or any integral
multiple of One Hundred Thousand Dollars ($100,000) in excess thereof) into
Eurodollar Loans; or

                (b) elect to convert any Eurodollar Loans into Base Rate Loans
on the last day of the Interest Period applicable to such Eurodollar Loans; or

                (c) elect to continue any Eurodollar Loans (or any part thereof
in an amount equal to Two Million Five Hundred Thousand Dollars ($2,500,000) or
any integral multiple of One Hundred Thousand Dollars ($100,000) in excess
thereof) as Eurodollar Loans on the last day of the Interest Period applicable
to such Eurodollar Loans.

        1.4 DURATION OF INTEREST PERIODS.

                (a) Subject to the provisions of the definition of Interest
Period and SECTION 1.2 and SECTION 1.3 above, the duration of each Interest
Period applicable to a Eurodollar Loan shall be as specified in the applicable
Notice of Conversion/Continuation.

                (b) If Administrative Agent does not receive a Notice of
Conversion/Continuation with respect to a Borrowing of Eurodollar Loans pursuant
to SUBSECTION (a) above within the applicable time limits specified herein,
Borrower shall be deemed to have elected to make or convert such Loans in whole
into Eurodollar Loans with an Interest Period of one month on the last day of
the then current Interest Period with respect thereto. Notwithstanding anything
to the contrary herein, any and all Eurodollar Loans shall be converted in whole
into Base Rate Loans on the last day of the then existing Interest Period with
respect thereto if Administrative Agent shall have received notice from Borrower
or a Lender that an Event of Default exists and Administrative Agent, at the
direction of Required Lenders, shall have delivered to Borrower notice that such
conversion is required.

                                       4.
<PAGE>

        1.5 EXISTING LOANS AND NOTICE AND MANNER OF MAKING ADDITIONAL LOANS OR
CONVERTING/CONTINUING LONG-TERM LOANS.

                (a) EXISTING LOANS. Set forth on SCHEDULE 1.5 hereto is a
schedule of all amounts invoiced under the QUALCOMM Procurement Agreements
through and including the Amendment Effective Date, which amounts have been
financed under Facility-1. Each such amount shall be deemed to be Tranche A
Loans, Tranche B Loans or Tranche C Loans thereunder pursuant to SECTION 1.1(e),
and the principal amount of each tranche shall be evidenced by a Term Pagares as
set forth in SECTION 1.6(d). SCHEDULE 1.5 also sets forth a schedule of all VAT
Loans outstanding on the Amendment Effective Date which the parties have agreed
will be financed under the VAT Facility and shall continue to be outstanding on
the terms set forth therein and shall be treated as VAT Loans hereunder on and
after the Amendment Effective Date.

                (b) NOTICE AND MANNER OF MAKING ADDITIONAL LOANS.

                        (i) Not fewer than five (5) Business Days prior to the
date Borrower desires to borrow hereunder, Borrower shall deliver by electronic
facsimile transmission: (A) to each of Administrative Agent and the applicable
Vendor, written notice specifying (1) whether proceeds of the requested Loan
shall be paid directly to a party not a Lender on behalf of Borrower, or paid to
Borrower as reimbursement for a certain amount of QUALCOMM Costs paid
out-of-pocket by Borrower to a third party; provided that, with respect to such
reimbursement, Borrower shall have delivered to Administrative Agent and the
applicable Vendor such notice, together with the applicable receipt or other
evidence of payment by Borrower, within 30 calendar days of such payment by
Borrower (in each case, a "Cash Advance"), or paid to a Lender (that is a
vendor) (a "Credit Advance"), (2) the amount of such Borrowing which, in the
case of a Cash Advance under either Long-Term Facility shall not be less than
the Minimum Borrowing Amount, (3) with respect to requests of Cash Advances, the
Person to which such Cash Advance is requested to be made on behalf of Borrower,
together with the contact and wire transfer information for such Person and (4)
the effective date for such Borrowing of Loans (which for Credit Advances shall
be no earlier than the date on which payment is due under the applicable
QUALCOMM Procurement Agreement), which notice shall be substantially in the form
of EXHIBIT C to this Agreement (a "Loan Request"); and (B) to the applicable
Vendor, all invoices and any other supporting documentary information necessary
to evidence the QUALCOMM Costs and VAT, if applicable, giving rise to such Loan
Request (the "Invoices). After the date on which the applicable Vendor receives
each Loan Request and the accompanying Invoices, the applicable Vendor shall
have four (4) Business Days (the "Loan Request Review Period") during which to
acknowledge receipt of the same and transmit such to Administrative Agent.
Provided that the applicable Vendor has acknowledged receipt of such Loan
Request and such Invoices to Administrative Agent in writing or, if the
applicable Vendor has not so acknowledged within the Loan Request Review Period,
the effective date for such Borrowing of such Loans under Credit Advances shall
be the first (1st) Business Day after the final day of such Loan Request Review
Period and the applicable Invoice shall be deemed paid to the extent of such
Loan.

                        (ii) On each date prior to the end of the Facility-1
Availability Period or the Facility-2 Availability Period, as applicable, on
which payment under any QUALCOMM

                                       5.
<PAGE>

Procurement Agreement is due for which Borrower has received an Invoice, and
such payment has not been made or a Borrowing of Long-Term Loans has not been
requested by Borrower pursuant to SECTION 1.5(b)(i) hereof, either Vendor may
deliver to Administrative Agent by electronic facsimile transmission written
notice of such due date and the amount of such payment due under the applicable
QUALCOMM Procurement Agreement (less any amounts as to which the applicable
Vendor and the Administrative Agent have received written notice from Borrower
of any dispute with respect to such amount being due and payable), which notice
shall be substantially in the form of EXHIBIT D to this Agreement (a "Notice of
Deemed Loan"), and a Borrowing of Base Rate Loans (which Loans shall be Tranche
A Loans, Tranche B Loans or Tranche C Loans as shall be determined pursuant to
SECTION 1.1(e)) shall be deemed to have been made as of the date on which such
payment was due pursuant to the applicable QUALCOMM Procurement Agreement and
the amount of Long-Term Loans owing to each Lender shall automatically be
increased to add to the principal amount thereof the amount of such required
payment according to the Commitment of each Lender making such Long-Term Loan as
of such date as to the applicable Vendor which is a Lender and as of the date,
as to any other Lender, that such Lender remits funds in respect of such Loan to
the Administrative Agent; provided, however, that Borrower may thereafter elect
to convert such Long-Term Loans in whole or in part to Eurodollar Loans in
accordance with SECTION 1.5(c) below.

                        (iii) With regard to Long-Term Loans which are Credit
Advances: (A) to the extent that, with respect to any Lender, the amount equal
to such Lender's Percentage under the applicable Facility multiplied by the
aggregate amount required to be paid by Borrower at such time under the QUALCOMM
Procurement Agreements exceeds amounts owing to such Lender under the QUALCOMM
Procurement Agreements on such date, such Lender shall, by 12:00 noon New York
time on the effective date of any Loan Request or within 2 Business Days after
receiving a Notice of a Deemed Loan, remit by wire transfer such excess to
Administrative Agent; and (B) to the extent that, with respect to any Lender,
the amount equal to such Lender's Percentage under the applicable Facility
multiplied by the aggregate amount required to be paid by Borrower at such time
under the QUALCOMM Procurement Agreements is less than the amount reported by
the applicable Vendor to Administrative Agent as amounts owing to such Lender
under the QUALCOMM Procurement Agreements, Administrative Agent shall promptly
remit (from amounts received by Administrative Agent pursuant to (A) above) by
wire transfer such shortfall to such Lender.

                        (iv) With regard to Loans that are Cash Advances,
Administrative Agent shall promptly notify each Lender having a Commitment with
respect thereto as to the content of each Loan Request or Notice of Deemed Loan.
Provided that with respect to Loan Requests that the applicable Vendor has
acknowledged Borrower's Loan Request to Administrative Agent in writing, such
Lenders shall disburse to Administrative Agent in immediately available funds by
12:00 noon New York time on the effective date of any Loan Request or within 2
Business Days of receiving a Notice of Deemed Loan an amount equal to their
respective Percentages multiplied by the amount of the Borrowing requested in
such Loan Request, and Administrative Agent shall promptly disburse the
aggregate of such amounts in immediately available funds to the applicable
Vendor or, if not payable to a Vendor, such other Person designated by the
Borrower in the Loan Request.

                                       6.
<PAGE>

                        (v) Nothing herein shall limit the ability of a Vendor
to deliver a Notice of Deemed Loan after an Event of Default or otherwise;
provided, that if a Notice of Deemed Loan is delivered after an Event of Default
and any Lender elects, based on the existence of such Event of Default, not to
remit funds in respect of such Loan as provided above, then such Loan shall be
deemed to be a Loan hereunder in favor of such Vendor and, if at such time such
Vendor shall not otherwise be a Lender hereunder, such Vendor shall upon the
giving of such Notice of Deemed Loan become a Lender hereunder to the extent of
such Loan.

        (c) CONVERSIONS/CONTINUATIONS OF LOANS. On each date on which Borrower
desires, with respect to Long-Term Loans to (A) continue any such Long-Term
Loans that are Eurodollar Loans for another Interest Period, or (B) convert any
such outstanding Long-Term Loans into Long-Term Loans of another type provided
for in this Agreement, Borrower shall notify Administrative Agent (which notice
shall be irrevocable) in writing by electronic facsimile transmission received
no later than 1:00 p.m. New York time on the date one (1) Business Day before
the day on which such requested Long-Term Loans are to be converted into Base
Rate Loans, and received no later than 1:00 p.m. New York time on the date three
(3) Business Days before the date on which such requested Long-Term Loans are to
be continued for another Interest Period as or converted into Eurodollar Loans.
Such notice shall specify (i) the effective date and amount of such Long-Term
Loans or portion thereof to be continued or converted, subject to the
limitations set forth in SECTION 1.3 hereof, (ii) the interest rate option to be
applicable thereto, and (iii) the duration of the applicable Interest Period, if
any (subject to the provisions of the definition of Interest Period and SECTION
1.4) hereof. Each such notification (a "Notice of Conversion/Continuation")
shall be in the form of EXHIBIT E to this Agreement. The Borrower shall execute
and deliver to the Administrative Agent for the account of each Lender a Notice
of Conversion/Continuation and each such notice shall specify the amount of the
Long-Term Loans or portion thereof payable to the respective Lender to be
continued or converted, which notice shall evidence the joint and several
guarantee "avalado" by the Guarantors and shall be attached to the Term Pagare
which evidences such Loans by the Administrative Agent (if it holds possession
of the Term Pagare) and otherwise by the Lender.

        (d) Administrative Agent shall promptly notify each Lender as to the
content of each Loan Request, Notice of Deemed Loan, and Notice of
Conversion/Continuation.

        (e) Unless Administrative Agent shall have been notified by any Lender
no later than the Business Day prior to the respective funding date of any
Borrowing of Loans that such Lender does not intend to make available to
Administrative Agent immediately available funds equal to such Lender's
Percentage under the relevant Facility of the total principal amount of such
Borrowing, Administrative Agent may (in its sole and absolute discretion) assume
that such Lender has advanced funds in the amount of such Lender's relevant
Percentage of such Borrowing to Administrative Agent on the applicable funding
date and Administrative Agent may, in reliance upon such assumption, make
available to Borrower corresponding funds. Administrative Agent agrees to give
prompt notice to Borrower in the event it advances funds on behalf of a Lender
under this SECTION 1.5(e); provided that failure to give such notice shall in no
way limit, restrict or otherwise affect Borrower's obligations or Administrative
Agent's or any Lender's rights or remedies under this Agreement and the other
Financing Agreements. If Administrative Agent has made funds available to
Borrower based on such assumption and such Loan is not in fact made available to
Administrative Agent by such Lender, Administrative

                                       7.

Agent shall be entitled to recover the corresponding amount of such Loan on
demand from such Lender. If such Lender does not promptly pay such corresponding
amount upon Administrative Agent's demand, Administrative Agent shall notify
Borrower and Borrower shall repay such Loan to Administrative Agent, together
with accrued interest thereon. Administrative Agent also shall be entitled to
recover from such Lender interest on such Loan in respect of each day from the
date such Loan was made by Administrative Agent to Borrower to the date such
corresponding amount is recovered by Administrative Agent at the Federal Funds
Effective Rate.

                (f) Nothing herein shall be deemed to relieve any Lender from
its obligation to fulfill its commitments hereunder or to prejudice any rights
which Borrower may have against any Lender as a result of any default by such
Lender hereunder.

        1.6 EVIDENCE OF DEBT.

                (a) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing indebtedness of Borrower to such
Lender resulting from each Loan made by such Lender from time to time, including
the amounts of principal and interest payable and paid to such Lender from time
to time under this Agreement.

                (b) Administrative Agent shall maintain the Lender Register
pursuant to SECTION 11.16, and a subaccount therein for each Lender, in which
shall be recorded (i) the amount of each Loan made hereunder, and each Interest
Period applicable thereto, (ii) the amount of any principal or interest due and
payable or to become due and payable from Borrower to each Lender hereunder
(including the amount of any capitalized interest under SECTION 1.8(e)) and
(iii) both the amount of any sum received by Administrative Agent hereunder from
Borrower and each Lender's share thereof.

                (c) The entries made in the Lender Register and the accounts of
each Lender maintained pursuant to SECTION 1.6(b) shall, to the extent permitted
by applicable law, be prima facie evidence of the existence and amounts of the
obligations of Borrower therein recorded; provided, that the failure of
Administrative Agent or any Lender to maintain the Lender Register or any such
account, or any error therein, shall not in any manner affect the obligation of
Borrower to repay (with applicable interest) the Loans of each Lender in
accordance with the terms of this Agreement.

                (d) With respect to each tranche of the Long-Term Loans made by
each Lender prior to the Amendment Effective Date, Borrower shall, as provided
in the Post-Closing Agreement, execute and deliver to Administrative Agent to
hold on behalf of such Lender a promissory note of Borrower payable to such
Lender substantially in the form of EXHIBIT A with appropriate insertions as to
issue date, principal repayment dates, principal amount, and Applicable Margin
(each, a "Term Pagare"), which promissory note shall be jointly and severally
guaranteed "avalado" by the Guarantors and shall be dated the date such
Long-Term Loan was made or deemed made. In addition, with respect to each
tranche of each Long-Term Loan made by a Lender on or after the Amendment
Effective Date, Borrower shall, within 5 Business Days of the day on which such
Loan is made or deemed made, execute and deliver to Administrative Agent to hold
on behalf of such Lender a Term Pagare for each tranche of such Long-Term Loan,
which promissory note shall be jointly and severally guaranteed "avalado" by

                                       8.
<PAGE>

the Guarantors and shall be dated the date such Loan is made or deemed made.
Notwithstanding anything to the contrary contained herein, upon the request of
the Administrative Agent at any time, Borrower shall promptly execute and
deliver to Administrative Agent to hold on behalf of such Lender a replacement
Term Pagare with respect to any Term Pagare theretofore issued in order to
conform the terms thereof to the terms of this Agreement, which replacement Term
Pagare shall be jointly and severally guaranteed "avalado" by the Guarantors and
shall be dated the date on which the replacement is to be effective.
Concurrently therewith, Administrative Agent or Lender, as the case may be,
shall return the replaced Term Pagare to Borrower.

                (e) With respect to VAT Loans (including any VAT Loans made
prior to the Amendment Effective Date not yet evidenced by a VAT Pagare),
Borrower agrees that Borrower will execute and deliver to each Lender making a
VAT Loan a VAT Pagare, which shall be jointly and severally guaranteed "avalado"
by the Guarantors, dated the date of issuance of such VAT Pagare evidencing the
VAT Loan made on that date. Thereafter, the VAT Loan evidenced by such VAT
Pagare and interest thereon shall at all times (including after assignment
pursuant to SECTION 11.4) be represented by such VAT Pagare in such form payable
to the order of the payee named therein. Borrower acknowledges that any VAT
Pagares issued prior to the Amendment Effective Date shall be treated as "VAT
Pagares" hereunder on and after such date.

                (f) Upon the written request of any Lender, Administrative Agent
shall forward to such Lender (i) all Pagares payable to such Lender received by
Administrative Agent on or prior to such date (the "Request Date") within ten
Business Days of receipt by Administrative Agent of such request, and (ii) all
Pagares payable to such Lender received by Administrative Agent after the
Request Date within ten Business Days of the receipt by Administrative Agent
thereof; provided, that any Lender requesting such delivery of its Pagares shall
reimburse Administrative Agent for all costs and expenses incurred by
Administrative Agent in the distribution thereof.

                (g) In the case of any conflict between the terms of this
Agreement and any Pagare, the terms of this Agreement shall control. Without
limiting the generality of the foregoing, all Loans made hereunder shall accrue
interest from the date such Loan is made and, to the extent not evidenced by a
Term Pagare, shall otherwise be treated as a Loan hereunder prior to Borrower's
execution of a Term Pagare evidencing such Loan.

        1.7 PRO RATA BORROWINGS. All Loans under this Agreement shall be made by
the Lenders pro rata on the basis of Commitments of the Lenders with a
Commitment under the Facility under which such Loan is being made. It is
understood that no Lender shall be responsible for any default by any other
Lender in its obligation to make Loans hereunder and that each Lender shall be
obligated to make the Loans provided to be made by it hereunder, regardless of
the failure of any other Lender to fulfill its commitments hereunder.

        1.8 INTEREST.

                (a) Except as provided in the next sentence with respect to VAT
Loans and as contemplated in SECTION 1.1(e), the outstanding principal amount of
each Loan shall bear interest from the date of the incurrence thereof until
payment maturity (whether by acceleration or otherwise) at a rate per annum
which shall at all times (i) in the case of Eurodollar Loans, and

                                       9.
<PAGE>

during each Interest Period applicable thereto, be the Eurodollar Rate for such
Interest Period plus the relevant Applicable Margin and (ii) in the case of Base
Rate Loans, be the Base Rate plus the relevant Applicable Margin. The
outstanding principal amount of each VAT Loan shall bear interest from the date
of the incurrence thereof until payment maturity (whether by acceleration or
otherwise) at a fixed rate per annum which shall at all times be the Applicable
VAT Margin plus the Eurodollar Rate in effect on the date of issuance of the VAT
Pagare associated with such VAT Loan (assuming an Interest Period of six months
commencing on such date).

                (b) All overdue principal and, to the extent permitted by law,
overdue interest in respect of each Loan and any other overdue amount payable
hereunder shall bear interest at a rate per annum equal to the rate otherwise
applicable thereto plus two percent (2%) per annum.

                (c) Except as provided in the next sentence with respect to VAT
Loans, interest shall accrue from and including the date of the incurrence of
Loans to but excluding the date of any repayment thereof and shall be payable
(i) in the case of Base Rate Loans, on the last Business Day of each calendar
quarter, and (ii) in the case of each Eurodollar Loan, on the last day of each
Interest Period applicable thereto and, in the case of an Interest Period in
excess of three months, on each date occurring at three month intervals after
the first day of such Interest Period and (iii) in the case of all Loans, on any
prepayment (on the amount prepaid), at maturity (whether by acceleration or
otherwise) and, after such maturity, on demand. Interest shall accrue from and
including the date of the incurrence of each VAT Loan to but excluding the date
of any repayment thereof and shall be payable on any prepayment (on the amount
prepaid), at maturity (whether by acceleration or otherwise) and, after such
maturity, on demand.

                (d) All computations of interest hereunder shall be made in
accordance with SECTION 11.7(b).

                (e) Anything in this Agreement to the contrary notwithstanding,
and unless Borrower shall notify Administrative Agent that this SECTION 1.8(e)
shall not be applicable to any of the interest payments on the Tranche A Loans
or the Tranche C Loans otherwise covered hereby, (i) the interest that accrues
on Tranche A Loans shall not be required to be paid in cash on any Interest
Payment Date occurring prior to the Facility-1 Refinancing Date and (ii) the
interest that accrues on Tranche C Loans shall not be required to be paid in
cash on any Interest Payment Date occurring prior to the first anniversary of
the Original Effective Date, but, in each case, on each such Interest Payment
Date such accrued interest will be capitalized and added to the principal of the
Tranche A Loans or Tranche C Loans of each Lender as to which such interest
accrued.

                (f) Administrative Agent, upon determining the interest rate for
any Borrowing of Eurodollar Loans for any Interest Period shall promptly notify
Borrower and the Lenders thereof.

                (g) So long as no Default or Event of Default shall have
occurred and be continuing on such date on which Borrower executes and delivers
the first agreement following the Amendment Effective Date which agreement
evidences Additional Senior Indebtedness and if the Alternative Margin in
connection therewith is less than the Applicable Margin applicable

                                      10.
<PAGE>

to the Tranche B Loans, the Applicable Margin in respect of the Tranche B Loans
shall be adjusted (once and only once) based on the Alternative Margin as
follows: (i) the Applicable Margin for Eurodollar Loans shall become the
Alternative Margin and (ii) the Applicable Margin for Base Rate Loans shall be
reduced by the same amount as the Applicable Margin for Eurodollar Loans was
reduced by the Alternative Margin. In the event that the Alternative Margin is
to be utilized, Borrower shall furnish to the Administrative Agent all
appropriate documentation relating to the Alternative Facility at least ten (10)
Business Days prior to the date it becomes effective. With respect to Eurodollar
Loans under Tranche B, the Alternative Margin shall become effective for the
first Interest Period (and all subsequent Interest Periods) immediately
following the execution and delivery of agreements evidencing such Alternative
Facility, and with respect to Base Rate Loans under Tranche B, the Alternative
Margin shall become effective on the Business Day immediately following the
execution and delivery of the agreements evidencing such Alternative Facility.

        1.9 INCREASED COSTS, ILLEGALITY, ETC.

                (a) In the event that (x) in the case of clause (i) below,
Administrative Agent or (y) in the case of clauses (ii) and (iii) below, any
Lender shall have determined in good faith (which determination shall, absent
manifest error, be final and conclusive and binding upon all parties hereto):

                        (i) on any date for determining the Eurodollar Rate for
any Interest Period that, by reason of any changes arising after the Original
Effective Date affecting the interbank Eurodollar market, adequate and fair
means do not exist for ascertaining the applicable interest rate on the basis
provided for in the definition of Eurodollar Rate; or

                        (ii) at any time, that such Lender shall incur increased
costs or reductions in the amounts received or receivable hereunder with respect
to any Eurodollar Loans (other than taxes covered by SECTION 3.4 and any
increased cost or reduction in the amount received or receivable resulting from
the imposition of or a change in the rate of taxes or similar charges) because
of (x) any change since the Original Effective Date in any applicable law,
governmental rule, regulation, guideline or order (or in the interpretation or
administration thereof and including the introduction of any new law or
governmental rule, regulation, guideline or order) (such as, for example, but
not limited to, a change in official reserve requirements) and/or (y) other
circumstances affecting the interbank Eurodollar market or the position of such
Lender in such market; or

                        (iii) at any time, that the making or continuance of any
Eurodollar Loan has become unlawful by compliance by such Lender in good faith
with any law, governmental rule, regulation or guideline introduced or changed
after the Original Effective Date;

then, and in any such event, such Lender (or Administrative Agent in the case of
clause (i) above) shall (x) on such date and (y) within ten Business Days of the
date on which such event no longer exists give notice (by telephone confirmed in
writing) to Borrower and to Administrative Agent of such determination (which
notice Administrative Agent shall promptly transmit to each of the other
Lenders). Thereafter (x) in the case of clause (i) above, until such time as
Administrative Agent notifies Borrower and the Lenders that the circumstances
giving

                                      11.
<PAGE>

rise to such notice by Administrative Agent no longer exist, all new Loans, and
all outstanding Loans as to which existing Interest Periods expire, shall bear
interest at a rate per annum equal to (A) the Base Rate plus (B) the Applicable
Margin, (y) in the case of clause (ii) above, Borrower shall pay to such Lender,
upon written demand therefor, such additional amounts (in the form of an
increased rate of, or a different method of calculating, interest or otherwise
as such Lender in its reasonable discretion shall determine after consultation
with Borrower) as shall be required to compensate such Lender for such increased
costs or reductions in amounts receivable hereunder (a written notice as to the
additional amounts owed to such Lender, describing the basis for such increased
costs and showing the calculation thereof, submitted to Borrower by such Lender
shall, absent manifest error, be final and conclusive and binding upon all
parties hereto) and (z) in the case of clause (iii) above, the obligations of
such Lender to make and maintain Loans hereunder under the respective Facilities
shall terminate and all of the outstanding Loans made by it shall be repaid.

                (b) If any Lender shall have determined that the adoption or
effectiveness after the Original Effective Date of any applicable law, rule or
regulation regarding capital adequacy, or any change therein after the Original
Effective Date, or any change after the Original Effective Date in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by such Lender or its parent corporation with any request
or directive made after the Original Effective Date regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on such Lender's or its parent corporation's capital or assets as a consequence
of its commitments or obligations hereunder to a level below that which such
Lender or its parent corporation could have achieved but for such adoption,
effectiveness, change or compliance (taking into consideration such Lender's or
its parent corporation's policies with respect to capital adequacy), then from
time to time, within 15 days after demand by such Lender (with a copy to
Administrative Agent), Borrower shall pay to such Lender such additional amount
or amounts as will compensate such Lender or its parent corporation for such
reduction. Each Lender, upon determining in good faith that any additional
amounts will be payable pursuant to this SECTION 1.9(b), will give prompt
written notice thereof to Borrower, which notice shall describe the basis for
such claim and set forth the calculation of such additional amounts, although
the failure to give any such notice shall not release or diminish any of
Borrower's obligations to pay additional amounts pursuant to this SECTION 1.9(b)
upon the subsequent receipt of such notice;

                (c) Notwithstanding the foregoing, a Lender shall not be
entitled to receive reimbursement for claimed costs pursuant to this SECTION 1.9
incurred more than 15 months prior to the date Lender provides notice of a claim
for reimbursement.

        1.10 COMPENSATION. Borrower shall compensate each Lender, upon its
written request (which request shall set forth the basis for requesting such
compensation), for all losses, expenses and liabilities (including, without
limitation, any loss, expense or liability incurred by reason of the liquidation
or reemployment of deposits or other funds required by such Lender to fund its
Eurodollar Loans but excluding in any event the loss of anticipated profits)
which such Lender may sustain: (i) if for any reason (other than a default by
such Lender or Administrative Agent) Eurodollar Loans are not incurred on a date
specified therefor in a Loan Request

                                      12.
<PAGE>

(whether or not withdrawn by Borrower); (ii) if any prepayment or repayment of
any of its Eurodollar Loans (other than VAT Loans) occurs on a date which is not
the last day of an Interest Period applicable thereto; (iii) if any prepayment
of any of its Eurodollar Loans (other than VAT Loans) is not made on any date
specified in a notice of prepayment given by Borrower; or (iv) as a consequence
of any other default by Borrower to repay its Eurodollar Loans when required by
the terms of this Agreement.

        1.11 CHANGE OF LENDING OFFICE. Each Lender agrees that, upon the
occurrence of any event giving rise to the operation of SECTION 1.9(a)(ii) OR
(iii), 1.9(b) OR 3.4 with respect to such Lender, it will, if requested by
Borrower, use reasonable efforts (subject to overall policy considerations of
such Lender) to designate another lending office for any Loans affected by such
event, provided that such designation is made on such terms that such Lender and
its lending office suffer no material economic, legal or regulatory
disadvantage, with the object of avoiding the consequence of the event giving
rise to the operation of any such Section. Nothing in this SECTION 1.11 shall
affect or postpone any of the obligations of Borrower or the right of any Lender
provided in SECTION 1.9, 1.10 or 3.

        1.12 EXIM FINANCING, ETC. QUALCOMM shall have the right to (i) attempt
to arrange and arrange at any time one or more EXIM Financings for each or both
Long-Term Facilities, with the entering into of such EXIM Financings to reduce
the respective Facility-1 Commitments and Facility-2 Commitments, as the case
may be, as provided for in SECTION 2.3; and/or (ii) attempt to arrange and
arrange for the Loans to be refinanced by other means, including a
subparticipation of the Commitments or a debt issue in the public markets (each
refinancing described in clause (i) or (ii), a "Refinancing"); provided,
however, that Borrower shall not be obligated to agree to any Refinancing if the
structure, costs, and other terms and conditions and other relevant factors
concerning the financing provided under any such Refinancing are not in the best
commercial interests of Borrower as compared to the structure, costs, and other
terms and conditions and other relevant factors concerning the financing
provided under this Agreement as they relate to the Loans and/or Commitments to
be refinanced; provided, further, that if Borrower and QUALCOMM disagree as to
whether the terms of any proposed Refinancing are in the best commercial
interests of Borrower, the parties shall submit the matter to an independent,
third party and internationally recognized investment banking firm mutually
agreeable to the parties for its determination, which determination shall be
binding on the parties hereto; and/or (iii) attempt to arrange and arrange for a
syndication that complies with the requirements of SECTION 11.4 of the
Commitments and Loans (a "Syndication"), it being agreed that Borrower and each
Credit Party will cooperate with QUALCOMM to negotiate in good faith any such
Refinancing and facilitate, as more fully described below, any such Syndication;
provided, however, that, within the 18 month period following the Original
Effective Date, (x) the Borrower shall not be obligated to, and QUALCOMM shall
not attempt to arrange, any refinancing of the type referred to in clause (ii)
above and (y) QUALCOMM shall not solicit any potential Lender in connection with
such Syndication which potential Lender is actively participating in the market
for transactions similar to the Senior Bank Financing or the High Yield Debt
financing; provided, further, that Borrower shall not be obligated to cooperate
in any such attempted Syndication by QUALCOMM more than three (3) times. Subject
to the terms of this SECTION 1.12, upon any Syndication attempt by QUALCOMM,
Borrower shall, at its expense, execute and deliver such documents, furnish such
information, attend such meetings, assist QUALCOMM and/or the Administrative
Agent, as the case may be, and take any and all

                                      13.
<PAGE>

actions as may be reasonably requested by QUALCOMM and/or the Administrative
Agent in connection with any such Syndication, and Borrower shall cause senior
management of Borrower to be available to assist with and accomplish any of the
foregoing. In connection with any such Refinancing or Syndication, Borrower may
request that proposed participants therein shall enter into the Common Agreement
and if so requested, it shall also be a condition of such Refinancing or
Syndication that such proposed participants enter Common Agreement.

        1.13 COMMON AGREEMENT. Concurrently herewith, each of the Agents and
each member of the Borrower Group shall enter into the Common Agreement.

        1.14 NO NET PAYMENTS. Borrower's obligation to make payments and perform
all other obligations hereunder, and the rights of Administrative Agent and
Lenders in and to such payments and performance, shall be absolute and
unconditional and shall not be subject to any abatement, reduction, set-off,
defense, counterclaim or recoupment for any reason whatsoever, including,
without limitation, abatements or reductions due to any present or future claims
of any Credit Party or their respective Affiliates against Administrative Agent,
any Lender, or any other Secured Party under this Agreement, the Common
Agreement, the QUALCOMM Procurement Agreements, the Alcatel Procurement
Agreement or any other Transaction Document or otherwise, against any vendor of
equipment or services used or planned to be used as part of the System, or
against any other Person for whatever reason. Except as otherwise expressly
provided herein, this Agreement shall not terminate, nor shall the obligations
of Borrower be affected, by reason of (a) any defect in or damage to, or any
loss or destruction of, any of the equipment or services provided pursuant to
the QUALCOMM Procurement Agreements or the Alcatel Procurement Agreement or
otherwise becoming part of the System from any cause whatsoever, (b) the
interference with the use of the System by Administrative Agent, any Lender, any
other Secured Party or any other Person, (c) any defect in title to the System
or any part thereof or any Lien on such title, or (d) any bankruptcy,
insolvency, reorganization or other proceeding relating to, or any action taken
by any trustee or receiver of, Administrative Agent, any Lender, any other
Secured Party or any other Person, or (e) for any other cause, whether similar
or dissimilar to the foregoing, any present or future law or regulation to the
contrary notwithstanding, whether or not such cause shall give rise to a claim
by any Credit Party or their respective Affiliates against any Lender under the
QUALCOMM Procurement Agreements or against Alcatel or any Alcatel Lender under
the Alcatel Credit Agreement or otherwise, it being the express intention of the
parties hereto that all amounts payable by Borrower hereunder shall be, and
continue to be, payable in all events unless the obligation to pay shall be
terminated pursuant to the express provisions of this Agreement. All payments
made by Borrower hereunder as required hereby shall be final, and Borrower shall
not seek to recover any such payment or any part thereof for any reason
whatsoever. Nothing in this Agreement shall, however, release or waive any claim
Borrower may have against Administrative Agent, any Lender or any other Person,
whether in connection with the QUALCOMM Procurement Agreements, this Agreement
or otherwise. If for any reason whatsoever this Agreement shall be terminated in
whole or in part by operation of law or otherwise, Borrower shall nonetheless,
to the extent permitted by applicable law, pay to Administrative Agent, on
behalf of Lenders, an amount equal to each payment payable hereunder at the time
and in the manner that such payment would have become due and payable under the
terms of this Agreement if it had not been terminated in whole or in part.

                                      14.

        1.15 REPLACEMENT OF LENDERS Upon the occurrence of any event giving rise
to the operation of SECTION 1.9(b) or SECTION 3.4 with respect to any Lender
which results in such Lender charging to the Borrower increased costs in excess
of those being charged generally by the Lenders or if a Lender has defaulted on
its obligation to make Loans hereunder, Borrower shall have the right, if no
Default or Event of Default then exists, to replace such Lender (the "Replaced
Lender") with one or more replacement lenders (collectively, the "Replacement
Lender") reasonably acceptable to Administrative Agent, provided that (i) at the
time of any replacement pursuant to this SECTION 1.15, the Replacement Lender
shall enter into one or more Assignment Agreements pursuant TO SECTION 11.4(b)
(and with all fees payable pursuant to said SECTION 11.4(b) to be paid by the
Replacement Lender) pursuant to which the Replacement Lender shall acquire all
of the Commitments and outstanding Loans of the Replaced Lender and, in
connection therewith, shall pay to the Replaced Lender in respect thereof an
amount equal to the sum of (A) an amount equal to the principal of, and all
accrued but unpaid interest on, all outstanding Loans of the Replaced Lender and
(B) an amount equal to all accrued, but unpaid, Commitment Fees owing to the
Replaced Lender pursuant to SECTION 2.1, and (ii) all obligations of the
Borrower owing to the Replaced Lender (other than those specifically described
in clause (i) above in respect of which the assignment purchase price has been,
or is concurrently being, paid) shall be paid in full to such Replaced Lender
concurrently with such replacement. Upon the execution of the respective
Assignment Agreement, the payment of amounts referred to in clauses (i) and (ii)
above and, if so requested by the Replacement Lender, delivery to the
Replacement Lender of the appropriate Pagares executed by the Borrower, the
Replacement Lender shall become a Lender hereunder and the Replaced Lender shall
cease to constitute a Lender hereunder, except with respect to indemnification
provisions applicable to the Replaced Lender under this Agreement, which shall
survive as to such Replaced Lender.

SECTION 2. FEES; COMMITMENTS.

        2.1 FEES.

                (a) Borrower agrees to pay to Administrative Agent a commitment
fee ("Commitment Fee") (x) for the account of each Lender with a Facility-1
Commitment, for each day during the Facility-1 Availability Period computed at
the rate of .50% per annum on the average daily Facility-1 Commitment of such
Lender, (y) for the account of each Lender with a Facility-2 Commitment, for
each day during each of the Facility-1 Availability Period and the Facility-2
Availability Period computed at the rate of (i) .25% per annum during the
Facility-1 Availability Period on the daily average Facility-2 Commitment of
such Lender and (ii) .50% per annum during the Facility-2 Availability Period on
the daily average Facility-2 Commitment of such Lender, and (z) for the account
of each Lender with a VAT Loan Commitment, for each day during the VAT Facility
Availability Period, computed at the rate of .50% per annum on the daily average
unutilized VAT Loan Commitment of such Lender. All such Commitment Fees shall be

September and December.

                (b) Borrower shall pay to QUALCOMM, for its own account, such

<PAGE>

                (c) All computations of Fees shall be made in accordance with
SECTION 11.7(b).

        2.2 VOLUNTARY REDUCTION OF COMMITMENTS. Upon at least five (5) Business
Days' prior written notice (or telephonic notice confirmed in writing) to
Administrative Agent (which notice shall be deemed to be given on a certain day
only if given before 1:00 p.m. (New York time) on such day and shall be promptly
transmitted by Administrative Agent to each of the Lenders), Borrower shall have
the right, without premium or penalty, to terminate or partially reduce (x) the
Total Facility-1 Commitment and/or the Total Facility-2 Commitment, provided
that any such partial reduction shall apply to proportionately and permanently
reduce the Commitments of each Lender under the affected Facility and/or (y) the
unutilized Total VAT Loan Commitment. Any partial reduction pursuant to this
Section 2.2 shall be in the amount of at least $1,000,000.

        2.3 MANDATORY ADJUSTMENTS OF COMMITMENTS, ETC.

present or future federal, state, or local income, payroll, withholding, social
security, sales, use, service, leasing excise, franchise, value added,
estimated, occupation, real and personal property, stamp, transfer, workers'
compensation, severance or other taxes, levies, imposts, duties, fees,
assessments or other charges of whatever nature now or hereafter imposed by any
jurisdiction or by any political subdivision or taxing authority thereof or
therein with respect to such payments (but excluding, except as provided in the
third succeeding sentence, any tax imposed on or measured by the net income or
net profits of a Lender pursuant to the laws of the jurisdiction in which it is
organized or any jurisdiction in which such Lender maintains a place of business
or any subdivision thereof or therein) and all interest, penalties addition
thereto or similar liabilities with respect to such nonexcluded taxes, levies,
imposts, duties, fees, assessments or other charges (all such nonexcluded taxes,
levies, imposts, duties, fees, assessments or other charges being referred to
collectively as "Taxes"). In addition, Borrower shall pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other Financing Agreement (hereinafter referred to as "Other
Taxes"). If any Taxes or Other Taxes are so levied or imposed, Borrower agrees
to pay the full amount of such Taxes or Other Taxes, and such additional amounts
as may be necessary so that every payment of all amounts due under this
Agreement or under any Pagare, after withholding or deduction for or on account
of any Taxes or Other Taxes, will not be less than the amount provided for
herein or in such Pagare. If any amounts are payable in respect of Taxes or
Other Taxes pursuant to the foregoing, Borrower agrees to reimburse such amounts
to each Lender, upon the written request of such Lender, such Taxes or Other
Taxes as are imposed on or measured by the net income or net profits of such
Lender pursuant to the laws of the jurisdiction in which the principal office or
applicable lending office of such Lender is located or under the laws of any
political subdivision or taxing authority of any such jurisdiction

                                      18.
<PAGE>

in which the principal office or applicable lending office of such Lender is
located and for any withholding of taxes as such Lender shall determine are
payable by, or withheld from, such Lender, in each case in respect of such
amounts so paid to or on behalf of such Lender pursuant to the foregoing and in
respect of any amounts paid to or on behalf of such Lender pursuant to this
sentence. Borrower will furnish to Administrative Agent within 45 days (or as
soon thereafter as available) after the date the payment of any Taxes or Other
Taxes is due pursuant to applicable law certified copies of receipts evidencing
such payment by Borrower. Borrower agrees to indemnify and hold harmless each
Lender, and immediately reimburse such Lender upon its written request, for the
amount of any Taxes or Other Taxes so levied or imposed and paid by such Lender.

                (b) If Borrower pays any additional amount under this SECTION
3.4 to a Lender and such Lender, in such Lender's sole and absolute
determination, has received or realized in connection therewith any refund or
any reduction of, or credit against, its tax liabilities in or with respect to
the taxable year in which the additional amount is paid, such Lender shall pay
to Borrower an amount equal to the net benefit, after tax, which was obtained by
the Lender in such year as a consequence of such refund, reduction or credit.
Such amount shall be paid as soon as practicable after receipt or realization by
such Lender of such refund, reduction or credit.

                (c) Each Lender shall use reasonable efforts (consistent with
legal and regulatory restrictions and subject to overall policy considerations
of such Lender) to file any certificate or document or to furnish any
information as reasonably requested by Borrower pursuant to any applicable
treaty, law or regulation, if the making of such filing or the furnishing of
such information would avoid the need for or reduce the amount of any amounts
payable by Borrower under SECTION 3.4(a); provided, however, that the failure of
any Lender to use such efforts shall not in any way diminish the obligations of
Borrower under this SECTION 3.4 or otherwise under this Agreement.

                (d) Notwithstanding anything in this SECTION 3.4 to the
contrary, Borrower shall have no obligation to make any payment of Taxes
pursuant to this SECTION 3.4 to any Lender, other than QUALCOMM, in excess of
such Gross Up Amounts which would be applicable in the case of payments to a
Registered Financial Institution.

statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to Borrower),
independent accountants and other experts selected by Administrative Agent.
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Financing Agreement unless it shall
first receive such advice or concurrence of Requisite Lenders as it deems
appropriate and indemnification for all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action,
provided, however, that Administrative Agent shall be justified in refusing to
take action if such action is in violation of law or the terms of this Agreement
or any other Financing Agreement, based on the advise of Administrative Agent's
legal counsel. Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement or any other
Financing Agreement in accordance with a request or consent of Requisite Lenders
and such request and any action taken or failure to act pursuant thereto shall
be binding upon all of Lenders.

                (b) For purposes of determining compliance with the conditions
precedent specified in SECTION 4 of this Agreement and Section 3 of the Common

to, approved or accepted or to be satisfied with each document or other matter
either sent by Administrative Agent to such Lender for consent, approval,
acceptance or satisfaction, or required thereunder to be consented to or
approved by or acceptable or satisfactory to such Lender, unless an officer of
Administrative Agent responsible for the transactions contemplated by the
Financing Agreements shall have received written notice from such Lender prior

objection shall not have been withdrawn by notice to Administrative Agent to
that effect or such Lender shall not have made available to Administrative Agent

                                      32.

Lenders in accordance with SECTION 8; provided, however, that unless and until

rely hereafter, on Administrative Agent to check or inquire on such Lender's
behalf into the adequacy, accuracy or completeness of any information provided
by Borrower or any other Person under or in connection with the Financing
Agreements or the transactions herein contemplated (whether or not the
information has been or is hereafter distributed to such Lender by
Administrative Agent). Each Lender represents to Administrative Agent that it
has, independently and without reliance upon Administrative Agent and based on
such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, prospects, operations,
property, financial and other condition and creditworthiness of Borrower, and
all applicable regulatory laws relating to the transactions contemplated
thereby, and made its own decision to enter into this Agreement and the other
Financing Agreements and extend credit to Borrower under and pursuant to this
Agreement. Each Lender also represents that it will, independently and without
reliance upon Administrative Agent and based on such documents and appraisals
and decisions in taking or not taking action under this Agreement and the other
Financing Agreements, and to make such investigations as it deems necessary to
inform itself as to the business, prospects, operations, property, financial and
other condition and creditworthiness of Borrower. Except for notices, reports
and other documents expressly herein required to be furnished to Lenders by
Administrative Agent, Administrative Agent shall not have any duty or
responsibility to provide to any Lender any credit or other information
concerning the business, prospects, operations, property, financial and other
condition or creditworthiness of Borrower which may come into the possession of
any Administrative Agent-Related Persons. Administrative Agent shall not be
responsible to any Lender for the execution, effectiveness, priority,
genuineness, validity, enforceability, collectability or sufficiency of this
Agreement, the Financing Agreements or for any representations or warranties,
recitals or statements made herein or therein or made in any written or oral
statements, or in any financial or other statements, instruments, reports or
certificates or any other documents furnished or made available by
Administrative Agent to Lenders or by or on behalf of Borrower to Administrative
Agent or any Lender in connection with the Financing Agreements or the
transactions contemplated thereby or for the financial condition or business
affairs of Borrower or any Person liable for payment of the Obligations, nor
shall Administrative Agent be required to ascertain or inquire as to the
performance or observance of any of the terms, conditions, provisions, covenants
or agreements contained in any of the Financing Agreements or as to the use of
proceeds of the Loans or as to the existence or possible existence of any
Default or Event of Default.

        10.7 INDEMNIFICATION. Whether or not the transactions contemplated
hereby are consummated, Lenders shall indemnify upon demand Administrative
Agent-Related Persons (to the extent not reimbursed by or on behalf of Borrower
and without limiting the obligation of Borrower to do so) ratably from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses and disbursements of any kind
whatsoever which may at any time (including at any time following the repayment
of the Loans or the termination or the resignation of the related Administrative
Agent) be imposed on, incurred by or asserted against any such Person in any way
relating to or arising out of this Agreement or any of the other Transaction
Documents or the transactions contemplated hereby or thereby or any action taken
or omitted by any such Person under or in connection with any of the foregoing;
provided, however, that no Lender shall be liable for the payment to
Administrative Agent-Related Persons of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from such Person's gross negligence or
willful misconduct. Without limitation of the foregoing, each Lender shall
reimburse Administrative Agent upon demand for its ratable share of any costs or
other out-of-pocket expenses (including reasonable attorneys' expenses and
disbursements) incurred by Administrative Agent in connection with the
preparation, execution, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal
advice in respect of rights or responsibilities under, this Agreement or any
other Transaction Document to the extent that Administrative Agent has not
previously been reimbursed for such expenses by or on behalf of Borrower.
Without limiting the generality of the foregoing, if any Governmental Authority
or any Administrative Agent did not properly withhold tax from amounts paid to
or for the account of any Lender (because the appropriate form was not
delivered, was not properly executed, or because such Lender failed to notify
Administrative Agent of a change in circumstances which rendered the exemption
from, or reduction of, withholding tax ineffective, or for any other reason),
such Lender shall indemnify Administrative Agent fully for all amounts paid,
directly or indirectly, by Administrative Agent as tax or otherwise, including
penalties and interest, and including any taxes imposed by any jurisdiction on
the amounts payable to Administrative Agent under this SECTION 10.7, together
with all costs and expenses (including reasonable attorneys' expenses and
disbursements). The obligations of Lenders in this SECTION 10.7 shall survive
the repayment of all Obligations and the termination of the Transaction
Documents.

        10.8 SUCCESSOR ADMINISTRATIVE AGENT. Administrative Agent may, and at
the request of Requisite Lenders shall, resign as Administrative Agent upon 30
days' notice to Lenders. If Administrative Agent shall resign as Administrative
Agent under this Agreement and the other Financing Agreements, then Requisite
Lenders shall appoint from among Lenders a successor Administrative Agent for
Lenders. If no successor Administrative Agent is appointed prior to the
effective date of the resignation of Administrative Agent, Administrative Agent
may appoint, after consulting with Lenders and Borrower, a successor
Administrative Agent from among Lenders. Upon the acceptance of its appointment
as successor Administrative Agent hereunder and under the other Financing
Agreements, such successor Administrative Agent shall succeed to the rights,
powers and duties of Administrative Agent, the term "Administrative Agent" shall
mean such successor Administrative Agent effective upon its appointment, and the
former Administrative Agent's appointment, rights, powers and duties as
Administrative Agent shall be terminated. After any retiring Administrative
Agent's resignation as Administrative Agent, the provisions of this SECTION 10
and SECTION 11.1 shall continue to inure to its benefit as to actions

                                      34.

taken or omitted to be taken by it while it was Administrative Agent under this
Agreement and the other Financing Agreements.

SECTION 11. MISCELLANEOUS.

        11.1 PAYMENT OF EXPENSES, INDEMNIFICATION, ETC.

               (a) (i) Borrower agrees to pay, or cause to be paid, to the

expenses (including, without limitation, the reasonable fees and expenses of one
common New York counsel and one common Mexican counsel to the Senior Lenders
(including the Lenders) and counsel for the Administrative Agent), in connection
with any amendment, modification, supplement or waiver of any other terms of the
Common Agreement, the Security Documents, this Agreement, the Pagares or the
other documents contemplated hereby and thereby; and (B) all reasonable costs
and expenses (including, without limitation, the reasonable fees and expenses of
one common New York and one common Mexican counsel to the Senior Lenders
(including the Lenders) and counsel for the Administrative Agent) in connection
with (X) any Default or Event of Default and any enforcement or collection
proceedings resulting therefrom or in connection with the negotiation of any
restructuring or "work-out" (whether or not consummated ) of the obligations of
Borrower hereunder and under the Pagares and (Y) the enforcement of this Section
11.1, in each case as evidenced in reasonable detail to the satisfaction of
Borrower, and (iii) pay and hold each of the Lenders harmless from and against
any and all present and future stamp and other similar taxes with respect to the
foregoing matters and save each of the Lenders harmless from and against any and
all liabilities with respect to or resulting from any delay or omission (other
than to the extent attributable to such Lender) to pay such taxes.

               (b) Borrower agrees to indemnify, save, and hold harmless
Administrative Agent, Lenders and their directors, officers, agents, attorneys
and employees (collectively, the "indemnitees") from and against: (i) any and
all claims, demands, actions, or causes of action that are asserted against any
indemnitee by any Person if the claim, demand, action, or cause of action arises
out of or relates to a claim, demand, action, or cause of action that the Person
asserts or may assert against Borrower, or any officer, director or shareholder
of Borrower in their capacity as such, (ii) any and all claims, demands, actions
or causes of action that are asserted against any indemnitee (other than by
Borrower or by another indemnitee) if the claim, demand, action or cause of
action arises out of or relates to the Loans, the use of proceeds of any Loans,
or the relationship of Borrower and Lenders under this Agreement or any
transaction contemplated pursuant to this Agreement, (iii) any administrative or
investigative proceeding by any governmental agency arising out of or related to
a claim, demand, action or cause of action described in clauses (i) or (ii)
above; and (iv) any and all liabilities, losses, costs, or expenses (including

indemnitee suffers or incurs as a result of any of the foregoing; provided, that
Borrower shall have no obligation under this SECTION 11.1 to any Lender or
Administrative Agent with respect to any of the foregoing arising out of the
gross negligence or willful misconduct of such Lender or Administrative Agent.

        11.2 RIGHT OF SETOFF. In addition to any rights now or hereafter granted
under applicable law or otherwise, and not by way of limitation of any such
rights, if an Event of

                                      35.
<PAGE>

Default then exists, each Lender is hereby authorized at any time or from time
to time, without presentment, demand, protest or other notice of any kind to any
Credit Party or to any other Person, any such notice being hereby expressly
waived, to set off and to appropriate and apply any and all deposits (general or
special but other than payroll accounts) and any other Indebtedness at any time
held or owing by such Lender (including, without limitation, by branches and
agencies of such Lender wherever located) to or for the credit or the account of
any Credit Party against and on account of the Obligations and liabilities of
such Credit Party to such Lender under this Agreement or under any of the other
Financing Agreements, including, without limitation, all interests in
Obligations of such Credit Party purchased by such Lender pursuant to SECTION
11.6(b), irrespective of whether or not such Lender shall have made any demand
hereunder and although said Obligations, liabilities or claims, or any of them,
shall be contingent or unmatured.

        11.3 NOTICES. Except as otherwise expressly provided herein, all notices
and other communications provided for hereunder shall be in writing (including
telex, telecopier, facsimile or electronic mail) and mailed, telexed,
telecopied, faxed, electronic mailed or delivered, if to a Credit Party, at the
address specified opposite its signature below or in the other relevant
Financing Agreements, as the case may be; if to any Lender, at its address
specified for such Lender on the signature pages hereto; or, at such other
address as shall be designated by any party in a written notice to the other
parties hereto. All such notices and communications shall be mailed, telexed,
telecopied, or electronic mailed or sent by overnight courier, and shall be
effective when received.

        11.4 BENEFIT OF AGREEMENT.

                (a) This Agreement shall be binding upon and inure to the
benefit of and be enforceable by the respective successors and assigns of the
parties hereto, provided that Borrower may not assign or transfer any of its
rights or obligations hereunder without the prior written consent of the
Lenders. Each Lender may at any time grant participations in any of its rights
hereunder or under any of the Pagares to one or more entities or institutions,
provided that in the case of any such participation, the participant shall not
have any rights under this Agreement or any of the other Financing Agreements
(the participant's rights against such Lender in respect of such participation
to be those set forth in the agreement executed by such Lender in favor of the
participant relating thereto) and all amounts payable by Borrower hereunder
shall be determined as if such Lender had not sold such participation, except
that the participant shall be entitled to the benefits of SECTIONS 1.9 and 3.4
of this Agreement to the extent that such Lender would be entitled to such
benefits if the participation had not been entered into or sold, and, provided
further that no Lender shall transfer, grant or assign any participation under
which the participant shall have rights to approve any amendment to or waiver of
this Agreement or any other Financing Agreement except to the extent such
amendment or waiver would (i) extend the final scheduled maturity of any Loan in
which such participant is participating (it being understood that any waiver of
the application of any prepayment or the method of any application of any
prepayment to the amortization of the Loans shall not constitute an extension of
the final maturity date), or reduce the rate or extend the time of payment of
interest or Fees thereon (except in connection with a waiver of the
applicability of any post-default increase in interest rates), or reduce the
principal amount thereof, or increase such participant's participating interest
in any Commitment over the amount thereof then in

                                      36.
<PAGE>

effect (it being understood that a waiver of any Default or Event of Default or
of a mandatory reduction in the Commitments, or a mandatory prepayment, shall
not constitute a change in the terms of any Commitment), (ii) release all or
substantially all of the Collateral or (iii) consent to the assignment or
transfer by Borrower of any of its rights and obligations under this Agreement.

                (b) Notwithstanding the foregoing and subject to the limitations
on Syndications set forth in SECTION 1.12, (x) any Lender may assign all or a
portion of its outstanding Loans and/or Commitments and its rights and
obligations hereunder to one or more other Lenders, and (y) with the consent of
QUALCOMM and Borrower (which consents shall not be unreasonably withheld) any
Lender may assign all or a portion of its outstanding Loans and/or Commitments
and its rights and obligations hereunder to one or more other entities or
institutions. No assignment pursuant to the immediately preceding sentence shall
to the extent such assignment represents an assignment to an institution other
than one or more Lenders hereunder, be in an aggregate amount less than the
lesser of (A) $5,000,000 (unless such assignee has agreed to purchase
assignments of interests under this Agreement in a series of transactions which,
in the aggregate, will total an original amount not less than $5,000,000) and
(B) if the amount of any Lender's outstanding Loans or Commitment shall be less
than $5,000,000, one hundred percent (100%) of such Lender's outstanding Loans
or Commitment. If any Lender so sells or assigns all or a part of its rights
hereunder, any reference in this Agreement to such assigning Lender shall
thereafter refer to such Lender and to the respective assignee to the extent of
their respective interests and the respective assignee shall have, to the extent
of such assignment (unless otherwise provided therein), the same rights and
benefits as it would if it were such assigning Lender. Each assignment pursuant
to this SECTION 11.4(b) shall be effected by the assigning Lender and the
assignee Lender executing an Assignment Agreement and giving Administrative
Agent written notice thereof. At the time of any such assignment, (i) either the
assigning or the assignee Lender shall pay to Administrative Agent a
nonrefundable assignment fee of $3,500; provided, that if the assignee has
agreed to purchase assignments of interests in a series of transactions, such
assignment fee shall be payable upon the first assignment of such series and
payable only once with respect to such entire series of transactions and no fee
shall be due in respect of any assignment to Qualcomm or any of its Affiliates,
(ii) SCHEDULE 1.0 shall be deemed to be amended to reflect the Commitments of
the respective assignee (which shall result in a direct reduction to the
Commitments of the assigning Lender) and of the other Lenders, and (iii)
Borrower will, if requested, issue new Pagares to the respective assignee and to
the assigning Lender. To the extent that an assignment pursuant to this SECTION
11.4(b) would, at the time of such assignment, result in increased costs under
SECTION 1.9 or 3.4 from those being charged by the respective assigning Lender
prior to such assignment, then Borrower shall not be obligated to pay such
increased costs (although Borrower shall be obligated to pay any other increased
costs of the type described above resulting from changes after the date of the
respective assignment). Each Lender and Borrower agree to execute such documents
(including without limitation amendments to this Agreement and the other
Financing Agreements) as shall be necessary to effect the foregoing. Nothing in
this clause (b) shall prevent or prohibit any Lender from pledging its Pagares
or Loans to a Federal Reserve Bank in support of borrowings made by such Lender
from such Federal Reserve Bank.

                (c) Notwithstanding any other provisions of this SECTION 11.4,
no transfer or assignment of the interests or obligations of any Lender
hereunder or any grant of participation therein shall be permitted if such
transfer, assignment or grant would require Borrower to file a

                                      37.
<PAGE>

registration statement with the SEC or to qualify the Loans under the "Blue Sky"
laws of any State.

                (d) Each Lender initially party to this Agreement hereby
represents, and each Person that became a Lender pursuant to an assignment
permitted by this SECTION 11.4 will, upon its becoming party to this Agreement,
represents that it makes loans in the ordinary course of its business and that
it will make or acquire Loans for its own account in the ordinary course of such
business, provided that subject to the preceding clauses (a) and (b), the
disposition of any promissory notes or other evidences of or interests in
Indebtedness held by such Lender shall at all times be within its exclusive
control.

        11.5 NO WAIVER; REMEDIES CUMULATIVE. No failure or delay on the part of
Administrative Agent or any Lender in exercising any right, power or privilege
hereunder or under any other Financing Agreement and no course of dealing
between any Credit Party and Administrative Agent or any Lender shall operate as
a waiver thereof; nor shall any single or partial exercise of any right, power
or privilege hereunder or under any other Financing Agreement preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege hereunder or thereunder. The rights and remedies herein expressly
provided are cumulative and not exclusive of any rights or remedies which
Administrative Agent or any Lender would otherwise have. No notice to or demand
on any Credit Party in any case shall entitle any Credit Party to any other or
further notice or demand in similar or other circumstances or constitute a
waiver of the rights of Administrative Agent or the Lenders to any other or
further action in any circumstances without notice or demand.

        11.6 PAYMENTS PRO RATA.

                (a) Administrative Agent agrees that promptly after its receipt
of each payment from or on behalf of any Credit Party in respect of any
Obligations of such Credit Party, it shall distribute such payment to the
Lenders (other than any Lender that has expressly waived its right to receive
its pro rata share thereof) pro rata based upon their respective shares, if any,
of the Obligations with respect to which such payment was received.

                (b) Each of the Lenders agrees that, if it should receive any
amount hereunder (whether by voluntary payment, by realization upon security, by
the exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Financing Agreements, or
otherwise) which is applicable to the payment of the principal of, or interest
on, the Loans or Fees, of a sum which with respect to the related sum or sums
received by other Lenders is in a greater proportion than the total of such
Obligation then owed and due to such Lender bears to the total of such
Obligation then owed and due to all of the Lenders immediately prior to such
receipt, then such Lender receiving such excess payment shall purchase for cash
without recourse or warranty from the other Lenders an interest in the
Obligations of the respective Credit Party to such Lenders in such amount as
shall result in a proportional participation by all of the Lenders in such
amount, provided that if all or any portion of such excess amount is thereafter
recovered from such Lender, such purchase shall be rescinded and the purchase
price restored to the extent of such recovery, but without interest.

                                      38.
<PAGE>

        11.7 CALCULATIONS; COMPUTATIONS. All computations of interest and Fees
hereunder shall be made on the actual number of days elapsed over a year of 360
days (365 or 366 days, as the case may be, in the case of Fees and Base Rate
Loans).

        11.8 GOVERNING LAW; SUBMISSION TO JURISDICTION; VENUE; WAIVER OF JURY
TRIAL.

                (a) This Agreement shall be governed by, and construed in
accordance with, the law of the State of New York, United States, without
reference to principles of conflicts of law (other than Section 5-1401 of the
General Obligations Laws of the State of New York); provided, however, that in
connection with any legal action or proceeding (other than an action to enforce
a judgment obtained in another jurisdiction) brought in respect to this
Agreement in the courts of Mexico or any political subdivision thereof, this
Agreement shall be deemed to be an instrument made under the laws of Mexico and
for such purposes shall be governed by, and construed in accordance with, the
laws of the Federal District of Mexico.

                (b) Each party hereto hereby agrees that any suit, action or
proceeding with respect to this Agreement or any judgment entered by any court
in respect thereof may be brought in the United States of America District Court
for the Southern District of New York, in the Supreme Court of the State of New
York sitting in New York County (including its Appellate Division), or in any
other appellate court in the State of New York or the competent courts of the
Federal District of Mexico, as the party commencing such suit, action or
proceeding may elect in its sole discretion; and each party hereto hereby
irrevocably submits to the jurisdiction of such courts for the purpose of any
such suit, action, proceeding or judgment. Each party hereto further submits,
for the purpose of any such suit, action, proceeding or judgment brought or
rendered against it, to the appropriate courts of the jurisdiction of its
domicile. Borrower hereby waives any rights to a specific jurisdiction it may
have by virtue of its present or any future domicile, or otherwise.

                (c) The Borrower hereby agrees that service of all writs,
process and summonses in any such suit, action or proceeding brought in the
State of New York may be made upon CT Corporation System, presently located at
1633 Broadway, New York, New York 10019, U.S.A. (the "Process Agent"), and the
Borrower hereby confirms and agrees that the Process Agent has been duly and
irrevocably appointed as its agent and true and lawful attorney-in-fact in its
name, place and stead to accept such service of any and all such writs, process
and summonses, and agrees that the failure of the Process Agent to give any
notice of any such service of process to the Borrower shall not impair or affect
the validity of such service or of any judgment based thereon. The Borrower
hereby further irrevocably consents to the service of process in any suit,
action or proceeding in said courts by the mailing thereof by the Lender by
registered or certified mail, postage prepaid, at its address set forth beneath
its signature hereto.

                (d) Nothing herein shall in any way be deemed to limit the
ability of the Lenders to serve any such writs, process or summonses in any
other manner permitted by applicable law or to obtain jurisdiction over Borrower
in such other jurisdictions, and in such manner, as may be permitted by
applicable law.

                (e) Borrower hereby irrevocably waives any objection that it may
now or hereafter have to the laying of the venue of any suit, action or
proceeding arising out of or

                                      39.
<PAGE>

relating to this Agreement or any other Financing Agreement brought in the
Supreme Court of the State of New York, County of New York, or in the United
States of America District Court for the Southern District of New York or the
competent courts of the Federal District of Mexico, and hereby further
irrevocably waives any claim that any such suit, action or proceeding brought in
any such court has been brought in an inconvenient forum.

                (f) The Borrower hereby agrees to cause the Process Agent to
execute and deliver to the Lender a letter from the Process Agent to the Lender
confirming Process Agent's acceptance of the appointment by Borrower prescribed
in SECTION 11.8(c).

        11.9 COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument. A set of counterparts
executed by all the parties hereto shall be lodged with Borrower and
Administrative Agent.

        11.10 EFFECTIVENESS. The Original Credit Agreement became effective on
September 25, 1998 (the "Original Effective Date"). This Agreement shall become

        11.11 HEADINGS DESCRIPTIVE. The headings of the several sections and
subsections of this Agreement are inserted for convenience only and shall not in
any way affect the meaning or construction of any provision of this Agreement.

        11.12 AMENDMENT OR WAIVER. Neither this Agreement nor any other Credit
Document nor any terms hereof or thereof may be changed, waived, discharged or
terminated unless such change, waiver, discharge or termination is in writing
signed by the respective Credit Parties party thereto and Required Lenders,
provided that no such change, waiver, discharge or termination shall, without
the consent of each Lender directly affected thereby, (i) extend the final
scheduled maturity date of any Facility or any Pagare, it being understood that
any waiver of any prepayment of, or the method of application of any prepayment
to the amortization of, the Loans shall not constitute any such extension, or
reduce the rate or extend the time of payment of interest (other than as a
result of waiving the applicability of any post-default increase in interest
rates) or Fees, or reduce the principal amount thereof, or increase the
Commitment of any Lender over the amount thereof then in effect (it being
understood that a waiver of any Default or Event of Default or of a mandatory
reduction in the Commitments shall not constitute a change in the terms of any
Commitment of any Lender), (ii) amend, modify or waive any provision of this
SECTION 11.12, (iii) reduce the percentage specified in, or (except to give
effect to any additional facilities hereunder) otherwise modify, the definition

                                      40.
<PAGE>

assignment or transfer by Borrower of any of its rights and obligations under
this Agreement, (v) establish any new obligations for any Lender or (vi) release
all or substantially all of the Collateral; provided that no such change,
waiver, discharge or termination shall, without the consent of Administrative
Agent, amend any provision of SECTION 10.

        11.13 SURVIVAL. All indemnities set forth herein including, without
limitation, in SECTION 1.9, 1.10, 3.4, 10.6 or 11.1 shall survive the execution
and delivery of this Agreement and the making and repayment of the Loans.

        11.14 DOMICILE OF LOANS. Each Lender may transfer and carry its Loans
at, to or for the account of any branch office, subsidiary or affiliate of such
Lender, provided that Borrower shall not be responsible for costs arising or
reimbursable under SECTION 1.9 or 3.4 resulting from any such transfer (other
than a transfer pursuant to SECTION 1.11) to the extent not otherwise applicable
to such Lender prior to such transfer.

        11.15 CONFIDENTIALITY. Subject to SECTION 11.4, the Lenders shall hold
all nonpublic information obtained pursuant to the requirements of this
Agreement which has been identified as such by Borrower in accordance with its
customary procedure for handling confidential information of this nature and in
accordance with safe and sound banking practices and in any event may make
disclosure to its Affiliates, employees, auditors, advisors, or counsel or as
reasonably required by any bona fide transferee or participant in connection
with the contemplated transfer of any Loans or participation therein (so long as
such transferee or participant agrees to be bound by the provisions of this
SECTION 11.15) or as required or requested by any governmental agency or
representative thereof or pursuant to legal process, provided that, unless
specifically prohibited by applicable law or court order, each Lender shall
notify Borrower of any request by any governmental agency or representative
thereof (other than any such request in connection with an examination of the
financial condition of such Lender by such governmental agency) for disclosure
of any such nonpublic information prior to disclosure of such information, and
provided further that in no event shall any Lender be obligated or required to
return any materials furnished by any Credit Party.

        11.16 LENDER REGISTER. Borrower hereby designates Administrative Agent
to serve as its agent, solely for purposes of this SECTION 11.16, to maintain a
register (the "Lender Register") on which it will record the Commitments from
time to time of each of the Lenders, the Loans made by each of the Lenders and
each repayment in respect of the principal amount of the Loans of each Lender.
Failure to make any such recordation, or any error in such recordation, shall
not affect Borrower's obligations in respect of such Loans. With respect to any
Lender, the transfer of the Commitments of such Lender and the rights to the
principal of, and interest on, any Loan made pursuant to such Commitments shall
not be effective until such transfer is recorded on the Lender Register
maintained by Administrative Agent and prior to such recordation all amounts
owing to the transferor with respect to such Commitments and Loans shall remain
owing to the transferor. The registration of assignment or transfer of all or
part of any Commitments and Loans shall be recorded by Administrative Agent on
the Lender Register only upon the acceptance by Administrative Agent of a
properly executed and delivered Agreement pursuant to SECTION 11.4(b). Borrower
agrees to indemnify Administrative Agent from and against any and all losses,
claims, damages and liabilities of whatsoever nature which may be imposed on,
asserted against or incurred by Administrative Agent in performing its duties
under this SECTION

                                      41.
<PAGE>
11.16 other than those resulting from Administrative Agent's willful misconduct
or gross negligence.

        11.17 JUDGMENT CURRENCY. Borrower agrees to indemnify QUALCOMM against
any loss incurred by it as a result of any judgment or order being given or made
for the payment of any amount due under any Pagare which is expressed and paid
in a currency (the "Judgment Currency") other than the currency in which such
amount was to be paid (the "Obligation Currency") and as a result of any
variation between (i) the rate of exchange at which the Obligation Currency
amount is converted into Judgment Currency for the purposes of such judgment or
order, and (ii) the rate of exchange at which QUALCOMM is able to purchase the
Obligation Currency with the amount of judgment currency actually received by
QUALCOMM. The foregoing indemnity shall constitute a separate and independent
obligation of Borrower and shall continue in full force and effect
notwithstanding any such judgment or order as aforesaid. The term "rate of
exchange" shall include any premiums and costs of exchange payable in connection
with the purchase of, or conversions into, the relevant currency.

        11.18 ENTIRE AGREEMENT; CONSTRUCTION.

                (a) This Agreement, the Pagares and the other Financing
Agreements, taken together, constitute and contain the entire agreement among
Borrower, the Lenders, and Administrative Agent and supersede any and all prior
agreements, negotiations, correspondence, understandings and communications
among the parties, whether written or oral, respecting the subject matter
hereof.

                (b) To the extent of any inconsistency between this Agreement
and any Pagare, the terms and conditions contained in this Agreement shall
govern.

                                      42.

       SECTION 4. REAFFIRMATION OF TERMS. This Amendment shall be construed in

implied agreement, obligation or understanding with Administrative Agent or any
Lender or any of Secured Parties' Agents, whether known or unknown, arising

different from or in addition to the express terms of any of the other Financing
Agreements; and (4) all other claims, causes of action or defenses of any kind
whatsoever (if any), whether known or unknown, which any member of the Borrower
Group might otherwise have against Administrative Agent or any Lender or any of
Secured Parties' Agents, on account of any Claims.

                     (c) EACH MEMBER OF THE BORROWER GROUP AGREES TO ASSUME THE
RISK OF ANY AND ALL UNKNOWN, UNANTICIPATED OR MISUNDERSTOOD DEFENSES, CLAIMS,
CAUSES OF ACTION, CONTRACTS, LIABILITIES, INDEBTEDNESS AND OBLIGATIONS WHICH ARE
RELEASED BY THIS AMENDMENT IN FAVOR OF ADMINISTRATIVE AGENT AND EACH LENDER AND
SECURED PARTIES' AGENTS, AND EACH MEMBER OF THE BORROWER GROUP HEREBY WAIVES AND

          "Facility-2 Availability Period" shall mean the period commencing on

     SECTION 3. REFERENCE TO AND EFFECT ON CREDIT AGREEMENT AND OTHER FINANCING
AGREEMENTS.

                                       1.
<PAGE>
          (a)  Upon the effectiveness of this Amendment, on and after the date
hereof, each reference in the Credit Agreement to "this Agreement,"
"hereunder," "hereof," "herein" or words of like import shall mean and be a
reference to the Credit Agreement as amended by this Amendment and each
reference in the Financing Agreements to the Credit Agreement shall also mean
and be a reference to the Credit Agreement as amended by this Amendment.

          (b)  The execution, delivery and effectiveness of this Amendment
shall not, except as expressly provided herein, operate as a waiver of any
right, power or remedy of the Administrative Agent or the Lenders under the
Credit Agreement or any of the Financing Agreements, nor constitute a waiver of
any provision of the Credit Agreement or any of the Financing Agreements.

     SECTION 4. REAFFIRMATION OF TERMS. This Amendment shall be construed in
connection with and as part of the Financing Agreements and all terms,
conditions, representations, warranties, covenants and agreements set forth in
the Financing Agreements, except as herein waived or amended, are hereby
ratified and confirmed and shall remain in full force and effect.

     SECTION 5. ACKNOWLEDGMENTS AND WAIVERS. Borrower hereby ratified and
reaffirms the validity and enforceability of all of the Liens and security
interests heretofore granted pursuant to the Common Agreement and the Security
Documents referred to therein, for the benefit of the Lenders, as collateral
security for the Senior Indebtedness, and acknowledges that all of such Liens
and security interests, and all collateral pledged as security for the Senior
Indebtedness, continues to be and remain collateral for the Senior Indebtedness
from and after the date hereof.

     SECTION 6. RELEASE AND WAIVER.

          (a)  Borrower hereby acknowledges and agrees that: (i) it has no
claim or cause of action against any Lender or the Administrative Agent, or any
of their officers, directors, employees, attorneys or other representatives or
agents under the Financing Agreements with respect to any condition, act,
omission, event, contract, liability, obligation, indebtedness, claim, cause of
action, defense, circumstance or matter of any kind whatsoever which existed,
arose or occurred at any time prior to the execution and delivery of this
Amendment or which could arise concurrently with the effectiveness of this
Amendment ("CLAIMS"); (ii) it has no offset or defense against any of its
respective obligations, indebtedness or contracts in favor of any Lender or the
Administrative Agent on account of any Claims; and (iii) it recognizes that
each Lender and the Administrative Agent has heretofore properly performed and
satisfied in a timely manner all of its obligations to and contracts with the
Borrower relating to the Financing Agreements.

          (b)  Although the Administrative Agent and Lenders regard their
conduct as proper and do not believe the Borrower to have any claim, cause of
action, offset or defense against any Lender or the Administrative Agent in
connection with the Financing Agreements, Lenders and the Administrative Agent
wish, and the Borrower agrees, to eliminate any possibility that any past
conditions, acts, omissions, events, circumstances or matters could impair or
otherwise affect any rights, interests, contracts or remedies of any Lender or
the Administrative Agent. Therefore, the Borrower unconditionally releases and
waives as to all

                                       2.

<PAGE>
Lenders and the Administrative Agent (1) any and all liabilities, indebtedness
and obligations, whether known or unknown, of any kind of any Lender or the
Administrative Agent to the Borrower arising under the Financing Agreements and
which exist on the date hereof, except the obligations remaining to be performed
by the Lenders as expressly stated in the Financing Agreements; (2) any legal,
equitable or other obligations or duties, whether known or unknown, of the
Lenders or of the Administrative Agent to the Borrower (and any rights of the
Borrower against any Lender or the Administrative Agent) arising under the
Financing Agreements and which exist on the date hereof besides those expressly
stated in the Financing Agreements; (3) any and all claims under any oral or
implied agreement, obligation or understanding with any Lender or the
Administrative Agent, whether known or unknown, arising under the Financing
Agreements and which exist on the date hereof; and (4) all other claims, causes
of action or defenses of any kind whatsoever (if any), whether known or unknown,
which the Borrower might otherwise have against any Lender or the Administrative
Agent, on account of any Claims.

          (c)  THE BORROWER AGREES TO ASSUME THE RISK OF ANY AND ALL UNKNOWN,
UNANTICIPATED OR MISUNDERSTOOD DEFENSES, CLAIMS, CAUSES OF ACTION, CONTRACTS,
LIABILITIES, INDEBTEDNESS AND OBLIGATIONS WHICH ARE RELEASED BY THIS AMENDMENT
IN FAVOR OF ANY LENDER OR THE ADMINISTRATIVE AGENT, AND THE BORROWER HEREBY
WAIVES AND RELEASES ALL RIGHTS AND BENEFITS WHICH IT MIGHT OTHERWISE HAVE UNDER
THE LAW OF THE STATE OF NEW YORK AND THE LAW OF THE FEDERAL DISTRICT OF MEXICO
WITH REGARD TO THE RELEASE OF SUCH UNKNOWN, UNANTICIPATED OR MISUNDERSTOOD
DEFENSES, CLAIMS, CAUSES OF ACTION, CONTRACTS, LIABILITIES, INDEBTEDNESS AND
OBLIGATIONS. TO THE EXTENT (IF ANY) WHICH ANY SUCH LAWS MAY BE APPLICABLE, THE
BORROWER WAIVES AND RELEASES (TO THE MAXIMUM EXTENT PERMITTED BY LAW) ANY RIGHT
OR DEFENSE WHICH IT MIGHT OTHERWISE HAVE UNDER ANY OTHER LAW OF ANY APPLICABLE
JURISDICTION WHICH MIGHT LIMIT OR RESTRICT THE EFFECTIVENESS OR SCOPE OF ANY OF
ITS WAIVERS OR RELEASES UNDER THIS AMENDMENT.

     SECTION 7. REPRESENTATIONS AND WARRANTIES. In order to induce the Lenders
and the Administrative Agent to enter into this Amendment, the Borrower hereby
represents, warrants and covenants to the Lenders and the Administrative Agent

                     (a) Each member of the Borrower Group hereby acknowledges
and agrees that: (i) it has no claim or cause of action against any Lender or
the Administrative Agent, or any of their officers, directors, employees,
attorneys or other representatives or agents under the Financing Agreements with
respect to any condition, act, omission, event, contract, liability, obligation,
indebtedness, claim, cause of action, defense, circumstance or matter of any

their conduct as proper and do not believe any member of the Borrower Group to
have any claim, cause of action, offset or defense against any Lender or the

contracts or remedies of any Lender or the Administrative Agent. Therefore, each
member of the Borrower Group unconditionally releases and waives as to all
Lenders and the Administrative Agent (1) any and all liabilities, indebtedness
and obligations, whether known or unknown, of any kind of any Lender or the
Administrative Agent to any member of the Borrower Group arising under the

and which exist on the date hereof besides those expressly stated in the
Financing Agreements; (3) any and all claims under any oral or implied
agreement, obligation or understanding with any Lender or the Administrative
Agent, whether known or unknown, arising

under the Financing Agreements and which exist on the date hereof; and (4) all
other claims, causes of action or defenses of any kind whatsoever (if any),
whether known or unknown, which any member of the Borrower Group might otherwise
have against any Lender or the Administrative Agent on account of any Claims.

                     (c) EACH MEMBER OF THE BORROWER GROUP AGREES TO ASSUME THE
RISK OF ANY AND ALL UNKNOWN, UNANTICIPATED OR MISUNDERSTOOD DEFENSES, CLAIMS,
CAUSES OF ACTION, CONTRACTS, LIABILITIES, INDEBTEDNESS AND OBLIGATIONS WHICH ARE
RELEASED BY THIS AMENDMENT IN FAVOR OF ANY LENDER OR THE ADMINISTRATIVE AGENT,

UNKNOWN, UNANTICIPATED OR MISUNDERSTOOD DEFENSES, CLAIMS, CAUSES OF ACTION,
CONTRACTS, LIABILITIES, INDEBTEDNESS AND OBLIGATIONS, TO THE EXTENT (IF ANY)
WHICH ANY SUCH LAWS MAY BE APPLICABLE, EACH MEMBER OF THE BORROWER GROUP WAIVES

MIGHT LIMIT OR RESTRICT THE EFFECTIVENESS OR SCOPE OF ANY OF ITS WAIVERS OR

3.    COMPENSATION AND BENEFITS

      (A)  Base Salary. The Executive will be paid an annual base salary
of $450,000., subject to adjustment as provided below (the "Salary"),
which will be payable in equal periodic installments according to the
Employer's customary payroll practices, but no less frequently than
monthly. The Salary will be reviewed by the Board of Directors not
less frequently than annually and may be adjusted upward or downward
in the sole discretion of the Boards of Directors, but in no event
will the Salary be less than $450,000. per year.

      (B)  Benefits. The Executive will, during the Employment Period,
be permitted to participate in such pension, profit sharing, bonus,
life insurance, hospitalization, major medical, and other employee
benefit plans of the Employer that may be in effect from time to time,
to the extent the Executive is eligible under the terms of those plans
(collectively, the "Benefits").  As  additionals Benefits, the
Executive shall be entitled to (i) an annual allowance toward the
maintenance of an automobile, which allowance shall be approximately
$10,000. annually; and (ii) an annual allowance of $50,000. toward the
payment of premiums on a policy or policies of life insurance on the
life of the Executive, the ownership and beneficiaries of which shall
be designated by the Executive.

      The Executive agrees to submit to any medical examination(s) and
provide any information and documents reasonably necessary for the
Employer to obtain any insurance required by this Agreement and "Key
Man" life insurance on the Executive's life.

      (C)   Annual Retirement Contribution. Commencing on the Effective
Date and during the Employment Period, the Executive will be entitled
to receive a Retirement Contribution in the amount of $150,000. per

<PAGE>   Exhibit 10.46 - Pg. 4

annum, to be paid periodically with the Executive's Salary
("Retirement Contribution").

      (D)   Annual Basic Bonus. During the Employment Period, the
Executive shall be paid a Basic Bonus (the "Basic Bonus") equal to
thirty-five (35%) percent of the total of his Salary plus Retirement
Contribution in the event that the defined EBIT (earnings before
interest expense, taxes and intercompany fees, charges and expenses,
all as defined in a certain Executive Compensation Recommendations
Report by CFS Consulting, Inc. dated September 20, 2001) (the "defined
EBIT") of ESG's operating subsidiaries (excluding extraordinary items)
reaches $6.5 million for each fiscal year.  The aforesaid Executive
Compensation Recommendations Report of CFS Consulting, Inc. excludes
amortization of goodwill and financing charges in arriving at the
defined EBIT and both of such items are also to be excluded in making
the computation required by this subparagraph.  The bonus required by
this subparagraph shall be paid not later than ninety (90) days after
the annual financial statements of ESG are completed.

      (E)   Annual Performance Bonus. During the Employment Period, the
Executive shall be paid a Performance Bonus (the "Performance Bonus")
equal to eight and one-third (8 1/3 %) percent of the defined EBIT of
ESG's operating subsidiaries (excluding extraordinary items) in excess
of $6.5 million for each fiscal year.  The aforesaid Executive
Compensation Recommendations Report of CFS Consulting, Inc. excludes
amortization of goodwill and financing charges in arriving at the
defined EBIT and both of such items are also to be excluded in making
the computation required by this subparagraph.  The bonus required by
this subparagraph shall be paid not later than ninety (90) days after
the annual financial statements of ESG are completed.

      (F)   Limitations on Compensation. In no event shall annual cash
compensation payable with respect to any single fiscal year during the
Employment Period, consisting of the total of Salary, Retirement
Contribution, Basic Bonus and Performance Bonus, exceed $875,000.  In
the event, however, that application of the formulae for computation
of Basic Bonus and Performance Bonus would result in annual
compensation in excess of $875,000., then cash compensation shall be
limited to $875,000., but all amounts earned in excess thereof shall
be credited to a non-qualified deferred compensation account and be
paid, without interest or other earnings thereon, at the Executive's
retirement, death, disability or upon a sale of all or substantially
all of ESG's assets or stock, provided further that the total of all
such compensation consisting of Salary, Retirement Contribution, Basic
Bonus and Performance Bonus, including amounts required to be credited
toward the above mentioned deferred compensation account shall not
exceed $1,250,000. for any fiscal year during the Employment Period.
The payment of any deferred compensation required by this subparagraph
shall be paid not later than ninety (90) days after the earliest date
on which the event occurs which requires the payment of the deferred
compensation account to the Executive.

<PAGE>   Exhibit 10.46 - Pg. 5

      (G)   Necessity to be Employed at End of Fiscal Year. In order to
be entitled to any payment of Basic Bonus and/or Performance Bonus for
any given fiscal year, the Executive shall be required to be employed
by the Employer at the end of each such fiscal year and, if not, there
shall be no pro rating of any such payment for any such fiscal year at
the end of which the Executive is not employed by the Employer.

      (H)   Auditors' Computations Binding. The computations of the
regular auditors of ESG shall be deemed accurate and binding, creating
a presumption of accuracy and regularity, which presumption may be
overcome only by a showing of fraud, impropriety, arithemetical error
or obvious irregularity. The defined EBIT is to be determined for each
fiscal year in a manner consistent with the illustrations set forth
and the method utilized in the aforesaid Executive Compensation
Recommendations Report of CFS Consulting, Inc. dated September 20,
2001, which illustrations and method are hereby incorporated herien by
reference as if fully set forth at length hereat.

4.    FACILITIES AND EXPENSES

      The Employer will furnish the Executive with office space,
equipment, supplies, and such other facilities and personnel as the
Employer deems necessary or appropriate for the performance of the

6.    TERMINATION

6.1   EVENTS OF TERMINATION

      The Employment Period, the Executive's Compensation, and any and
all other rights of the Executive under this Agreement or otherwise as

6.2   DEFINITION OF DISABILITY

      For purposes of Section 6.1, the Executive will be deemed to have
a "disability" if, for physical or mental reasons, the Executive is
unable to perform the essential functions of the Executive's duties
under this Agreement for 120 consecutive days, or 180 days during any
twelve month period, as determined in accordance with this Section
6.2. The disability of the Executive will be determined by a medical
doctor selected by written agreement of the Employer and the Executive
upon the request of either party by notice to the other. If the
Employer and the Executive cannot agree on the selection of a medical
doctor, each of them will select a medical doctor and the two medical
doctors will select a third medical doctor who will determine whether
the Executive has a disability. The determination of the medical
doctor selected under this Section 6.2 will be binding on both
parties. The Executive must submit to a reasonable number of
examinations by the medical doctor making the determination of
disability under this Section 6.2, and the Executive hereby authorizes
the disclosure and release to the Employer of such determination and
all supporting medical records. If the Executive is not legally
competent, the Executive's legal guardian or duly authorized attorney-
in-fact will act in the Executive's stead, under this Section 6.2, for
the purposes of submitting the Executive to the examinations, and
providing the authorization of disclosure, required under this Section
6.2.

6.3   DEFINITION OF "FOR CAUSE"

      For purposes of Section 6.1, the phrase "for cause" means: (a)
the Executive's material breach of this Agreement which breach
continues for more than thirty (30) days after notice thereof has been
received by the Executive; (b) the Executive's failure to adhere to
any written Employer policy if the Executive has been given a
reasonable opportunity to comply with such policy or cure his failure
to comply (which reasonable opportunity shall not exceed thirty (30)
days); (c) the appropriation (or attempted appropriation) of a
material business opportunity of the Employer, including attempting to
secure or securing any personal profit in connection with any
transaction entered into on behalf of the Employer; (d) the
misappropriation (or attempted misappropriation) of any of the
Employer's funds or property; or (e) the conviction of, the indictment

or plea of no contest with respect to, a felony, the equivalent
thereof, or any other crime with respect to which imprisonment for
more than six (6) months is a possible punishment.

      The Executive and the Employer acknowledge that the purchase
price paid for the Acquired Business, as set forth in the Asset
Purchase Agreement, was based in part on the Executive's commitment to
continue to serve as Chief Executive Officer of the Acquired Business.
Accordingly, if the Executive commits an act described in Sections 6.3
(a), (b), (c), (d) or (e) and the Employer elects to terminate the
Executive's employment, Employer shall be relieved of its obligation
to make any of the contingent payments required by Sections 2.4 (a),
(b) or (c) of the Asset Purchase Agreement subsequent to the date of
such termination.

breach of the Asset Purchase Agreement which breach continues for more
than thirty (30) days after notice has been received by the Employer.

6.5   TERMINATION PAY

      Effective upon the termination of this Agreement, the Employer
will be obligated to pay the Executive (or, in the event of his death,
his designated beneficiary as defined below) only such compensation as
is provided in this Section 6.5 and in lieu of all other amounts and
in settlement and complete release of all claims the Executive may
have against the Employer. For purposes of this Section 6.5, the
Executive's designated beneficiary will be such individual beneficiary
or trust, located at such address, as the Executive may designate by
notice to the Employer from time to time or, if the Executive fails to
give notice to the Employer of such a beneficiary, the Executive's
estate. Notwithstanding the preceding sentence, the Employer will have
no duty, in any circumstances, to attempt to open an estate on behalf
of the Executive, to determine whether any beneficiary designated by
the Executive is alive or to ascertain the address of any such
beneficiary, to determine the existence of any trust, to determine
whether any person or entity purporting to act as the Executive's
personal representative (or the trustee of a trust established by the
Executive) is duly authorized to act in that capacity, or to locate or
attempt to locate any beneficiary, personal representative, or
trustee.

      (A)   Termination by the Executive for Good Reason. If the

by either party as a result of the Executive's disability, as
determined under Section 6.2, the Employer will pay the Executive his
Salary and normal disability and medical insurance benefits for a
period of one (1) year after the date of termination for disability.

      (D)   Termination upon Death. If this Agreement is terminated
because of the Executive's death, the Executive or his beneficiaries
or, in the absence of any designated beneficiaries, his estate, will
be entitled to receive his Salary for a period of one (1) year after
the date of death.

      (E)   Sale. If this Agreement is terminated as a result of a sale
as provided hereinabove in Section 6.1(e), the Executive will be
entitled to receive his Salary and Retirement Contribution for a
period of six (6) months after the closing of such sale and the amount
credited to the Executive's non-qualified, non-interest bearing and
non-income earning deferred compensation account, as set forth in
Section 3(F) hereof.

      (F)   Benefits. The Executive's accrual of, or participation in
plans providing for, the Benefits will cease at the effective date of
the termination of this Agreement, and the Executive will be entitled
to accrued Benefits pursuant to such plans only as provided in such
plans; provided, however, that upon the expiration of the term of the
Executive's employment, and provided that the Executive is in
compliance with all Post-Employment Period obligations, the Employer
shall endeavor to continue the Executive's participation in the
Employer's health insurance plan until such time as the Executive
reaches age 65. The Employer shall not be required to pay any premiums
on behalf of the Executive in excess of those paid during the
Executive's last year of employment with the Employer.

      (G)   In addition to the foregoing, within ninety (90) days from
the date of termination, for any reason whatsoever, all amounts, if
any, standing to the credit of the Executive in his non-qualified
deferred compensation account as set forth in Section 3(F) shall be
paid to the Executive or his representative.

7.    NON-DISCLOSURE COVENANT; EMPLOYEE INVENTIONS

7.1   ACKNOWLEDGMENTS BY THE EXECUTIVE

      The Executive acknowledges that (a) during the Employment Period
and as a part of his employment, the Executive will be afforded access
to Confidential Information; (b) public disclosure of such
Confidential Information could have an adverse effect on the Employer
and its business; (c) because the Executive possesses substantial
technical expertise and skill with respect to the Employer's business,

<PAGE>   Exhibit 10.46 - Pg. 9

the Employer desires to obtain exclusive ownership of each Employee
Invention, and the Employer will be at a substantial competitive
disadvantage if it fails to acquire exclusive ownership of each
Employee Invention; (d) the Buyer has required that the Executive make
the covenants in this Section 7 as a condition to its purchase of the
Acquired Business; and (e) the provisions of this Section 7 are
reasonable and necessary to prevent the improper use or disclosure of
Confidential Information and to provide the Employer with exclusive
ownership of all Employee Inventions.

7.2   AGREEMENTS OF THE EXECUTIVE

      In consideration of the compensation and benefits to be paid or
provided to the Executive by the Employer under this Agreement, the
Executive covenants as follows:

(A)   Confidentiality.

      (i)   During and following the Employment Period, the Executive
      will hold in confidence the Confidential Information and will not
      disclose it to any person except with the specific prior written
      consent of the Employer or except as otherwise expressly
      permitted by the terms of this Agreement.

      (ii)  Any trade secrets of the Employer will be entitled to all of
      the protections and benefits under New York and any other
      applicable law. If any information that the Employer deems to be
      a trade secret is found by a court of competent jurisdiction not
      to be a trade secret for purposes of this Agreement, such
      information will, nevertheless, be considered Confidential
      Information for purposes of this Agreement. The Executive hereby
      waives any requirement that the Employer submit proof of the
      economic value of any trade secret or post a bond or other
      security.

      (iii) None of the foregoing obligations and restrictions applies
      to any part of the Confidential Information that the Executive
      demonstrates was or became generally available to the public
      other than as a result of a disclosure by the Executive.

      (iv)  The Executive will not remove from the Employer's premises
      (except to the extent such removal is for purposes of the
      performance of the Executive's duties at home or while traveling,
      or except as otherwise specifically authorized by the Employer)
      any document, record, notebook, plan, model, component, device,
      or computer software or code, whether embodied in a disk or in
      any other form (collectively, the "Proprietary Items"). The
      Executive recognizes that, as between the Employer and the
      Executive, all of the Proprietary Items, whether or not developed
      by the Executive, are the exclusive property of the Employer.
      Upon termination of this Agreement by either party, or upon the
      request of the Employer during the Employment Period, the
      Executive will return to the Employer all of the Proprietary
      Items in the Executive's possession or subject to the Executive's

<PAGE>   Exhibit 10.46 - Pg. 10

      control, and the Executive shall not retain any copies,
      abstracts, sketches, or other physical embodiment of any of the
      Proprietary Items.

(B)   Employee Inventions. Each Employee Invention will belong
exclusively to the Employer. The Executive acknowledges that all of
the Executive's writing, works of authorship, specially commissioned
works, and other Employee Inventions are works made for hire and the
property of the Employer, including any copyrights, patents, or other
intellectual property rights pertaining thereto. If it is determined
that any such works are not works made for hire, the Executive hereby
assigns to the Employer all of the Executive's right, title, and
interest, including all rights of copyright, patent, and other
intellectual property rights, to or in such Employee Inventions. The
Executive covenants that he will promptly:

      (i)   disclose to the Employer in writing any Employee Invention;

      (ii)  assign to the Employer or to a party designated by the
      Employer, at the Employer's request and without additional
      compensation, all of the Executive's right to the Employee
      Invention for the United States and all foreign jurisdictions;

      (iii) execute and deliver to the Employer such applications,
      assignments, and other documents as the Employer may request in
      order to apply for and obtain patents or other registrations with
      respect to any Employee Invention in the United States and any
      foreign jurisdictions;

      (iv)  sign all other papers necessary to carry out the above
      obligations; and

      (v)   give testimony and render any other assistance in support of
      the Employer's rights to any Employee Invention.

7.3   DISPUTES OR CONTROVERSIES

The Executive recognizes that should a dispute or controversy
arising from or relating to this Agreement be submitted for
adjudication to any court, arbitration panel, or other third party,
the preservation of the secrecy of Confidential Information may be
jeopardized. All pleadings, documents, testimony, and records relating
to any such adjudication will be maintained in secrecy and will be
available for inspection by the Employer, the Executive, and their
respective attorneys and experts, who will agree, in advance and in
writing, to receive and maintain all such information in secrecy,
except as may be limited by them in writing.

8.    NON-COMPETITION AND NON-INTERFERENCE

8.1   ACKNOWLEDGMENTS BY THE EXECUTIVE

      The Executive acknowledges that: (a) the services to be performed
by him under this Agreement are of a special, unique, unusual,
extraordinary, and intellectual character; (b) the Employer's business

<PAGE>   Exhibit 10.46 - Pg. 11

is currently regional in scope but may become national in scope and
its products are currently marketed in five or more regions but may in
the future be marketed throughout the United States; (c) the Employer
competes with other businesses that are or could be located in any
part of the United States; (d) the Buyer has required that the
Executive make the covenants set forth in this Section 8 as a
condition to the Buyer's purchase of the Acquired Business; and (e)
the provisions of this Section 8 are reasonable and necessary to
protect the Employer's business.

8.2   COVENANTS OF THE EXECUTIVE

      In consideration of the acknowledgments by the Executive, and in
consideration of the compensation and benefits to be paid or provided
to the Executive by the Employer, the Executive covenants that he will
not, directly or indirectly:

      (a)  during the Employment Period, except in the course of his
employment hereunder, and during the Post-Employment Period, engage or
invest in, own, manage, operate, finance, control, or participate in
the ownership, management, operation, financing, or control of, be
employed by, associated with, or in any manner connected with, lend
the Executive's name or any similar name to, lend Executive's credit
to or render services or advice to, any business whose products or
activities compete in whole or in part with the products or activities
of the Employer; provided, however, that the Executive may purchase or
otherwise acquire up to (but not more than) one percent of any class
of securities of any enterprise (but without otherwise participating
in the activities of such enterprise) if such securities are listed on
any national or regional securities exchange or have been registered
under Section 12(g) of the Securities Exchange Act of 1934;

      (b)  whether for the Executive's own account or for the account
of any other person, at any time during the Employment Period and the
Post-Employment Period, solicit business of the same or similar type
being carried on by the Employer, from any person known by the
Executive to be a customer of the Employer, whether or not the
Executive had personal contact with such person during and by reason
of the Executive's employment with the Employer;

      (c)  whether for the Executive's own account or the account of any
other person (i) at any time during the Employment Period or the Post-
Employment Period, solicit, employ, or otherwise engage as an
employee, independent contractor, or otherwise, any person who is or
was an employee of the Employer at any time during the Employment
Period or in any manner induce or attempt to induce any employee of
the Employer to terminate his employment with the Employer; or (ii) at
any time during the Employment Period or the Post Employment Period,
interfere with the Employer's relationship with any person, including
any person who at any time during the Employment Period was an
employee, contractor, supplier, or customer of the Employer; or

<PAGE>   Exhibit 10.46 - Pg. 12

      (d)  at any time during or after the Employment Period, disparage
the Employer or any of its shareholders, directors, officers,
employees, or agents.

For purposes of this Section 8.2, the term "Post-Employment Period"
means the two year period beginning on the date of termination of the
Executive's employment with the Employer.

      If any covenant in this Section 8.2 is held to be unreasonable,
arbitrary, or against public policy, such covenant will be considered
to be divisible with respect to scope, time, and geographic area, and
such lesser scope, time, or geographic area, or all of them, as a
court of competent jurisdiction may determine to be reasonable, not
arbitrary, and not against public policy, will be effective, binding,
and enforceable against the Executive.

      The period of time applicable to any covenant in this Section 8.2
will be extended by the duration of any violation by the Executive of
such covenant.

      The Executive will, while the covenant under this Section 8.2 is
in effect, give notice to the Employer, within ten days after
accepting any other employment, of the identity of the Executive's
employer. The Employer may notify such employer that the Executive is
bound by this Agreement and, at the Employer's election, furnish such
employer with a copy of this Agreement or relevant portions thereof.

9.    GENERAL PROVISIONS

9.1   INJUNCTIVE RELIEF AND ADDITIONAL REMEDY

      The Executive acknowledges that the injury that would be suffered
by the Employer as a result of a breach of the provisions of this
Agreement (including any provision of Sections 7 and 8) would be
irreparable and that an award of monetary damages to the Employer for
such a breach would be an inadequate remedy. Consequently, the
Employer will have the right, in addition to any other rights it may
have, to obtain injunctive relief to restrain any breach or threatened
breach or otherwise to specifically enforce any provision of this
Agreement, and the Employer will not be obligated to post bond or
other security in seeking such relief. Without limiting the Employer's
rights under this Section 9 or any other remedies of the Employer, if
the Executive breaches any of the provisions of Section 7 or 8, the
Employer will have the right to cease making any payments otherwise
due to the Executive under this Agreement.

9.2   COVENANTS OF SECTIONS 7 AND 8 ARE ESSENTIAL AND INDEPENDENT
      COVENANTS

      The covenants by the Executive in Sections 7 and 8 are essential
elements of this Agreement and the Asset Purchase Agreement, and
without the Executive's agreement to comply with such covenants, the
Buyer would not have purchased the Acquired Business under the Asset

<PAGE>   Exhibit 10.46 - Pg. 13

Purchase Agreement and the Employer would not have entered into this
Agreement or employed the Executive. The Employer and the Executive
have independently consulted their respective counsel and have been
advised in all respects concerning the reasonableness and propriety of
such covenants, with specific regard to the nature of the business
conducted by the Employer.

      The Executive's covenants in Sections 7 and 8 are independent
covenants and the existence of any claim by the Executive against the
Employer under this Agreement or otherwise, or against the Buyer, will
not excuse the Executive's breach of any covenant in Section 7 or 8.

      If the Executive's employment hereunder expires or is terminated,
this Agreement will continue in full force and effect as is necessary
or appropriate to enforce the covenants and agreements of the
Executive in Sections 7 and 8.

9.4   REPRESENTATIONS AND WARRANTIES BY THE EXECUTIVE

      The Executive represents and warrants to the Employer that the
execution and delivery by the Executive of this Agreement do not, and
the performance by the Executive of the Executive's obligations
hereunder will not, with or without the giving of notice or the
passage of time, or both: (a) violate any judgment, writ, injunction,
or order of any court, arbitrator, or governmental agency applicable
to the Executive; or (b) conflict with, result in the breach of any
provisions of or the termination of, or constitute a default under,
any agreement to which the Executive is a party or by which the
Executive is or may be bound.

9.5   OBLIGATIONS CONTINGENT ON PERFORMANCE

      The obligations of the Employer hereunder, including its
obligation to pay the compensation provided for herein, are contingent
upon the Executive's substantial performance of the Executive's
obligations hereunder.

9.6   WAIVER

      The rights and remedies of the parties to this Agreement are
cumulative and not alternative. Neither the failure nor any delay by
either party in exercising any right, power, or privilege under this
Agreement will operate as a waiver of such right, power, or privilege,
and no single or partial exercise of any such right, power, or
privilege will preclude any other or further exercise of such right,
power, or privilege or the exercise of any other right, power, or
privilege. To the maximum extent permitted by applicable law: (a) no
claim or right arising out of this Agreement can be discharged by one
party, in whole or in part, by a waiver or renunciation of the claim
or right unless in writing signed by the other party; (b) no waiver
that may be given by a party will be applicable except in the specific
instance for which it is given; and (c) no notice to or demand on one
party will be deemed to be a waiver of any obligation of such party or

<PAGE>   Exhibit 10.46 - Pg. 14

of the right of the party giving such notice or demand to take further
action without notice or demand as provided in this Agreement.

9.7   BINDING EFFECT; DELEGATION OF DUTIES PROHIBITED

      This Agreement shall inure to the benefit of, and shall be
binding upon, the parties hereto and their respective successors,
assigns, heirs, and legal representatives, including any entity with
which the Employer may merge or consolidate or to which all or
