Borrower from time to time on or after the applicable conditions precedent in
Section 3 have been satisfied (or waived by QUALCOMM) in an aggregate amount up
to the lesser of (i) QUALCOMM's unused Facility-2 Commitment (which is

Agreement is entered into on or before March 31, 2002, the earlier of (x) a date
(to be specified in writing by QUALCOMM) no later than 90 calendar

                                      -6-            INTERIM FUNDING AGREEMENT

days after the closing date of the Sale Transaction, on terms and conditions set
forth in the Sale Transaction Proceeds Allocation Agreement, or (y) the date ten
Business Days after such Definitive Agreement is terminated, revoked or
rescinded by any party to the Definitive Agreement (the "Special Loan Scheduled
Maturity Date").


                  (c) Interest Rate Applicable to Interim Loans. Borrower shall
pay interest on the unpaid principal amount of each Interim Loan from the date
of the funding of such Interim Loan until such Interim Loan is paid at a fixed
rate equal to twelve percent (12%) per annum; provided, however, that if (i) the
Definitive Agreement is entered into by March 31, 2002, (ii) the Sale
Transaction closes on the terms and conditions set forth in such Definitive
Agreement, and (iii) the Interim Loans are timely repaid in accordance with
Section 2.2(b)(iii)(x), then the Interim Loans will be deemed not to bear
interest. In the event that such Interim Loan is not timely repaid in accordance
with Section 2.2(b)(iii)(x), interest on such Interim Loan shall accrue at a
rate per annum equal to the Eurodollar Rate plus ten percent (10%) and the per
annum interest rate applicable to such Interim Loans shall increase by one
percent (1%) each month until such Interim Loan and all accrued interest thereon
has been paid in full; provided, however, that the interest rate on such Interim
Loans shall in no event exceed twenty-two percent (22%) per annum. All interest
under this Section 2.2(c) shall be computed on the basis of a year of 360 days
and the actual number of days elapsed.

         2.3 The Additional Interim Financing.

                  (a) Additional Interim Loan Commitment. Subject to the terms
and conditions set forth in this Agreement, QUALCOMM agrees to make Additional
Interim Loans to Borrower from time to time after the applicable conditions
precedent in Section 3 have been satisfied (or waived by QUALCOMM) in an
aggregate amount up to $100,000,000.00 (the "Additional Interim Loan
Commitment").

                  (b) Repayment of Additional Interim Loans. The Additional
Interim Loans, together with all accrued and unpaid interest (subject to the
provisions set forth in Section 2.3(c)), shall be due and payable on the Special
Loan Scheduled Maturity Date.

                  (c) Interest Rate Applicable to Additional Interim Loans.
Borrower shall pay interest on the unpaid principal amount of each Additional
Interim Loan from the date of the funding of such Additional Interim Loan until
such Additional Interim Loan is repaid at a fixed rate equal to twelve percent
(12%) per annum; provided, however, that if (i) the Sale Transaction closes on
the terms and conditions set forth in the Definitive Agreement and (ii) the
Additional Interim Loans are timely repaid in accordance with Section 2.3(b),
then the Additional Interim Loans will have been deemed to bear interest at a
rate applicable for a Eurodollar Rate with a three-month Interest Period, which
Eurodollar Rate shall have been selected on the previous Quarterly Date, or if
such Quarterly Date is not a Business Day, the immediately preceding Business
Day. In the event that such Additional Interim Loan is not timely repaid in
accordance with Section 2.3(b), interest on such Additional Interim Loan shall
accrue at a rate per annum equal to the Eurodollar Rate plus ten percent (10%)
and the per annum interest rate applicable to such Additional Interim Loans
shall increase by one percent (1%) each month until such Additional Interim Loan

conditions precedent set forth in Sections 3.1 and 3.3, QUALCOMM shall have been
deemed to have made a Facility-2 Loan in the amount of $5,000,000.00 (the
"Backstop Fee Loan") pursuant to the terms and conditions of the Credit
Agreement. Upon receipt of the duly executed Backstop Fee Loan Pagare from
Borrower, if requested from Borrower, QUALCOMM shall deliver to Borrower a
written acknowledgment that the Backstop Fee has been paid. QUALCOMM's
commitment under this Section 2.4(a) to make the Backstop Fee Loan is
duplicative of, and not in addition to, the Facility-2 Commitment, and
utilization or reduction of one shall automatically utilize or reduce the other.
The Facility-2 Commitments of QUALCOMM shall be reinstated in accordance with
their terms to the extent that such Backstop Fee Loan is repaid by Borrower
pursuant to Section 2.4(b) prior to June 30, 2002.

                  (b) Repayment of Backstop Fee Loan. The Backstop Fee Loan,
together with all accrued and unpaid interest (subject to the provisions set
forth in Section 2.4(c)), shall be due and payable on the Special Loan Scheduled
Maturity Date.

                  (c) Interest Rate Applicable to Backstop Fee Loan. Borrower
shall pay interest on the unpaid principal amount of the Backstop Fee Loan from
the date of the funding of the Backstop Fee Loan until such Backstop Fee Loan is
repaid at a fixed rate equal to twelve percent (12%) per annum; provided,
however, that if (i) the Sale Transaction closes on the terms and conditions set
forth in the Definitive Agreement and (ii) the Backstop Fee Loan is timely
repaid in accordance with Section 2.4(b), then the Backstop Fee Loan will have
been deemed to bear interest at a rate applicable for a Eurodollar Rate, with a
three-month Interest Period which Eurodollar Rate shall have been selected on
the previous Quarterly Date, or if such Quarterly Date is not a Business Day,
the immediately preceding Business Day. In the event that such Backstop Fee Loan
is not timely repaid in accordance with Section 2.4(b), interest on such
Backstop Fee Loan shall accrue at a rate per annum equal to the Eurodollar Rate
plus ten percent (10%) and the per annum interest rate applicable to such
Backstop Fee Loans shall increase by one percent (1%) each month until such
Backstop Fee Loan and all accrued interest thereon has been paid in full;
provided, however, that the interest rate on such Backstop Fee Loans shall in no
event exceed twenty-two percent (22%) per annum. All interest under this Section
2.4(c) shall be computed on the basis of a year of 360 days and the actual
number of days elapsed.

         2.5 Participations. QUALCOMM may, without the consent of Borrower, sell
participations to one or more shareholders (or their affiliates) of Holdings
(each, a "Participant") in all or a portion of QUALCOMM's rights and obligations
under this Agreement and the Pagares (including all or a portion of its Interim
Loan Commitment and its Additional Interim Loan Commitment and the Special Loans
owing to it); provided that (a) each such Participant shall participate in the
Interim Loans (and the Interim Loan Commitment) and the Additional Interim Loans
(and the Additional Interim Loan Commitment) in a minimum percentage amount
equal to its percentage ownership interest in Holdings and (b) QUALCOMM shall
enter into a Participation Agreement with each Participant. The Participation
Agreement shall provide that

                                      -8-            INTERIM FUNDING AGREEMENT
<PAGE>
QUALCOMM shall retain the sole right to enforce this Agreement and the
Credit Agreement and to approve any amendment, modification or waiver of any
provision of this Agreement and the Credit Agreement except as expressly set
forth in the Participation Agreement; provided that such agreement or instrument
may provide that QUALCOMM will not, without the consent of the Participant,
agree to a reduction of the principal of or interest rate applicable to Special
Loans in which such Participant has an interest or the extension of the Special
Loan Scheduled Maturity Date (other than as contemplated by Section 2.2(b)) of
any Special Loans in which such Participant has an interest.

         2.6 Termination of the Special Loan Commitments. The Special Loan
Commitments and QUALCOMM's obligations to make Special Loans thereunder shall
terminate upon the occurrence of any of the following:

                  (a) Event of Default. An Event of Default (other than a Known
Vendor Facilities Default) shall occur under the Financing Agreements or the

                  (c) Failure to Achieve Conditions Precedent by a Date Certain.
With respect to the Interim Loan Commitment, such Interim Loan Commitment shall
terminate without any further action on the part of QUALCOMM if the Closing Date
has not occurred on or before January 31, 2002. With respect to the Additional
Interim Loan Commitment, such Additional Interim Loan Commitment shall terminate
on the first to occur of (i) if QUALCOMM, in its sole discretion, has determined
that the Sale Transaction will not be consummated, the date, which date shall be
on or after February 15, 2002, that QUALCOMM delivers a notice to Borrower of
QUALCOMM's determination with respect to the Sale Transaction, (ii) without any
further action on the part of QUALCOMM, on March 31, 2002, if the conditions
precedent set forth in Section 3.2 have not been satisfied by such date and
(iii) termination of the Interim Loan Commitment.

                  (d) Termination of Facility-2 Commitment. If the Facility-2
Commitment under the Credit Agreement is terminated pursuant to the terms and
conditions of the Credit Agreement, the Special Loan Commitments shall terminate
without any further action on the part of QUALCOMM. A termination of the Special
Loan Commitments pursuant to Sections 2.6(a), (b) or (c) of this Agreement shall
not constitute an automatic termination of the Facility-2 Commitments under the
Credit Agreement.

that would cause the aggregate amount of Operating Costs, Working Capital,
Capital Expenditures and Financing Costs incurred by Borrower in such monthly
period to exceed by ten percent (10%) or more of the aggregate amount provided

was budgeted to have been made in any prior month (limited to the Interim

                              Regulatory Approvals



                  (a)  By January 22, 2002, delivery of evidence
satisfactory to QUALCOMM of the filing of a writ before the DGIE requesting an
official communication containing an authorization allowing the participation of
one hundred percent (100%) of foreign investment directly in Borrower or
indirectly through Holdings.

                  (b)  If, as a consequence of the filing of the writ
described in paragraph (a) above, and in order for the DGIE to authorize the
participation of one hundred percent (100%) of foreign investment as described
therein, the DGIE formally requests the divestiture of the wireless mobile
telephony business on the one hand and the wireless fixed telephony business on
the other hand in two separate titles of concession (the "Divestiture Notice"),
then, within a period of ten Business Days after Borrower and/or Holdings
receive such Divestiture Notice, Borrower or Holdings, as the case may be, shall
deliver evidence satisfactory to QUALCOMM of the filing of a writ before the SCT
requesting (i) the divestiture of the wireless mobile telephony business on the
one hand and the wireless fixed telephony business on the other hand in two
separate titles of concession, and (ii) the assignment of the wireless fixed
telephony business to Finanzas (or to any other qualified assignee member of the
Borrower Group).

                  (c)  If any of the authorizations provided in paragraphs
(a) or (b) above is granted, then Borrower or Holdings, as the case may be,
shall obtain any and all approvals necessary from any Governmental Authority to
amend its and/or their bylaws, as the case may be, in order to allow the
participation of one hundred percent (100%) of foreign investment directly in
Borrower or indirectly through Holdings.

                  All of the above in the understanding that QUALCOMM's Mexican
counsel shall be given the opportunity to (a) attend each of the meetings that
take place in order to obtain any of the authorizations described above, and (b)
comment and complement each of the writs to be filed before any Governmental
Authority, including, without limitation, the SCT and the DGIE, provided that
Borrower or Holdings, as the case may be, shall not be compelled to include such
comments in any such writs.
