          date hereof shall promulgate or adopt principles that are materially
          different from those in effect at December 31, 1997, the Borrower and
          the Lenders will endeavor in good faith to amend this Agreement in
          order to amend:

          (i)  the definition of GAAP to include such different principles; and

          (ii) the other provisions of this Agreement so as to reflect in
               substance the same limitations and restrictions as in effect
               prior to such amendment to the definition of GAAP.

          Prior to the effective date, if any, of any such amendment, GAAP
          shall, however, continue to include only the principles specified in
          clause (a)(i) above.

     (c)  CONTINGENT OBLIGATION: the amount of any Contingent Obligation of a
          Person shall be deemed to be an amount equal to the stated or
          determinable amount of the primary obligation in respect of which such
          Contingent Obligation is made or, if not stated or determinable, the
          maximum reasonably anticipated liability in respect thereof as
          determined by such Person in good faith.

same day funds as the Disbursement Date of the proposed Advance to such account

     (a)  The Borrower shall pay interest on the amount of any principal,
          interest, fee or other amount payable hereunder or under any Loan

          period beginning on such date or, as the case may be, the date of such
          judgment and ending on the date upon which the obligation of the
          Borrower to pay such sum (the balance thereof for the time being
          unpaid being herein referred to as an "unpaid sum") is discharged
                                                 ----------
          which period shall be divided into successive periods, each of which
          (other than the first) shall start on the last day of the preceding
          such period and the duration of each of which shall be selected by the
          Administrative Agent, at a rate per annum equal at all times to 2.00%
          per annum plus the LIBOR Rate plus the Margin.

          respect of an unpaid sum shall be due and payable and shall be paid by
          the Borrower at the end of the period by reference to which it is
          calculated or on such other dates as the Administrative Agent may
          specify by written notice to the Borrower.

SECTION 3.5   INTEREST PERIOD.

     (a)  The duration of each Interest Period shall be one, three or six months
          in each case as the Borrower may, by not less than three Business Days
          prior written notice to the Administrative Agent, select, or such
          other period as is agreed with the Lenders; provided that:
                                                      --------

          (i)  if the Borrower fails to give such notice for any Interest
               Period, the duration of that Interest Period shall, subject to
               clauses (ii)-(vi) below, be three months;

          (ii) whenever the last day of any Interest Period would otherwise
               occur on a day other than a Business Day, the last day of such
               Interest Period shall be extended to occur on the next-succeeding
               Business Day;

         (iii) if such extension referred to in clause (ii) would cause the last
               day of such Interest Period to occur in the next-following
               calendar month, the last day of such Interest Period shall occur
               on the next-preceding Business Day;

                                       35
<PAGE>

          (iv) whenever the first day of any Interest Period occurs on the last
               day of a calendar month or one for which there is no numerically
               corresponding Business Day in the later month in which such
               Interest Period ends, such Interest Period shall end on the last
               Business Day of such later month; and

          (v)  the Borrower may select an initial Interest Period for each
               Advance that permits it to comply with Section 2.6; and

          (vi) no Interest Period shall extend beyond the next date upon which a
               payment of principal is scheduled or known by the Borrower (at
               the time of selection of such Interest Period) to be due to be
               made pursuant to this Agreement.

     (b)  When two or more Advances have Interest Periods that end on the same
          day, then, on the last day of those Interest Periods, the Advances to
          which such Interest Periods relate shall be consolidated into (and
          thereafter, save as otherwise provided herein, be treated in all
          respects as) a single Advance.

SECTION 3.6   INTEREST RATE DETERMINATION.

If:

     (a)  with respect to any Advance, the Required Lenders notify the
          Administrative Agent that LIBOR for any Interest Period for such
          Advance will not adequately reflect the cost to such Required Lenders
          of making, funding or maintaining their Commitment Percentages for
          such Advance for such Interest Period, the Administrative Agent shall
          forthwith so notify the Borrower and the Lenders, whereupon:

          (i)  the interest payable on each Advance will automatically, from and
               including the last day of the then-existing Interest Period
               therefor, be calculated at the rate per annum equal to the Base
               Rate plus the Margin; and

          (ii) the obligations of the Lenders to make Advances shall be
               suspended immediately,

          until such time as the Administrative Agent shall notify the Borrower
          and the Lenders that the circumstances causing such suspension no
          longer exist; or

     (b)  the Administrative Agent cannot determine LIBOR for any Advance:

          (i)  the Administrative Agent shall forthwith notify the Borrower and
               the Lenders that the interest rate cannot be determined for such
               Advance;

          (ii) the interest payable on each such Advance will automatically,
               from and including the last day of the then-existing Interest
               Period therefor, be calculated at the rate per annum equal to the
               Base Rate; and

                                       36
<PAGE>

         (iii) the obligation of the Lenders to make Advances shall be suspended
               immediately,

          until the Administrative Agent shall notify the Borrower and the
          Lenders that the circumstances causing such suspension no longer
          exist; or

     (c)  if, as a result of any event or other circumstances, the interest
          payable hereunder on any Advance is required by this Agreement to be
          determined by reference to the Base Rate and the Administrative Agent
          is unable for any reason to determine the Base Rate (including if Bank
          of America National Trust and Savings Association does not offer or
          publicize its reference rate) then:

          (i)  the Administrative Agent shall promptly notify the Borrower and
               the Lenders that an event or circumstance has arisen, the result
               of which is that the Administrative Agent is unable to determine
               the Base Rate; and

          (ii) if the Administrative Agent or the Borrower so requires, within
               five days of such notification the Administrative Agent and the
               Borrower shall enter into negotiations with a view to agreeing
               between the Required Lenders and the Borrower a substitute basis
               (A) for determining the rates of interest from time to time
               applicable to the Advances and/or (B) upon which the Advances may
               be maintained thereafter and any such substitute basis that is
               agreed shall take effect in accordance with its terms and be
               binding on each party hereto; and

         (iii) if the Administrative Agent and the Borrower have entered into
               such negotiations and an agreement acceptable to the Required
               Lenders and the Borrower is not reached within two Business Days
               of the date of entry into such negotiations, the rate of interest
               applicable to the Advances denominated in such currency from time
               to time during an Interest Period shall be the rate per annum
               which is the sum of the Margin and the rate per annum determined
               by the Administrative Agent to be the average (rounded upwards to
               one hundredth of one percent) of the rates notified by each
               Lender to the Administrative Agent before the last day of such
               Interest Period to be those which express as a percentage rate
               per annum the cost to such Lender of funding from whatever
               sources it may reasonably select its portion of such Advance
               during such Interest Period.

SECTION 3.7   PAYMENT AND COMPUTATIONS.

     (a)  The Borrower and the Lenders shall each make each payment by it
          hereunder not later than 11:00 a.m. (New York time) on the day when
          due in Dollars to the Administrative Agent at the Administrative
          Agent's Account in same-day funds. Payment shall be deemed to have
          been made for all purposes under this Agreement when received by the
          Administrative Agent at the Administrative Agent's Account in New
          York.

                                       37

     (b)  The Administrative Agent will, promptly after its receipt thereof,
          cause to be distributed funds of the kind received relating to the
          payment of principal or interest or fees and other amounts ratably to
          the Lenders in accordance with their Commitment Percentages.

     (c)  Upon the Administrative Agent's acceptance of an Assignment and
          Acceptance and recording of the information contained therein in the
          Register pursuant to Section 14.9(d), from and after the effective
          date specified in such Assignment and Acceptance, the Administrative
          Agent shall make all payments hereunder in respect of the interest
          assigned thereby to the Lender assignee thereunder, and the parties to
          such Assignment and Acceptance shall make all appropriate adjustments
          in such payments for periods prior to such effective date directly
          between themselves.

     (d)  All computations of:

          (i)  interest (except if determined by reference to the Base Rate) and
               fees shall be made by the Administrative Agent on the basis of a
               year of 360 days; and

         (ii)  interest determined by reference to the Base Rate shall be made
               by the Administrative Agent on the basis of a year of 365 days,

          for the actual number of days (including the first day but excluding
          the last day) occurring in the period for which such interest or fees
          are payable.

     (e)  Each determination by the Administrative Agent of an interest rate
          hereunder shall be conclusive and binding for all purposes, absent
          manifest error.

     (f)  Whenever any payment hereunder shall be stated to be due on a day
          other than a Business Day, such payment shall be made on the
          succeeding Business Day, unless such Business Day is in the following
          calendar month, in which case such payment shall be made on the
          preceding Business Day.

     (g)  To the extent permitted by Applicable Law, all payments by the
          Borrower hereunder and under any of the other Loan Documents shall be
          made without setoff or counterclaim.

     (a)  upon and subject to the terms of:

          (i)  the EKN General Conditions; and

          (ii) the EKN Undertaking,

          in respect of each Advance, promptly:

               (A)  on behalf of the Lenders and to the extent it is reasonably
                    able, submit the relevant application form to EKN for the
                    issuance of an EKN Guarantee in respect of such Advance; and

               (B)  effect payment of any premium payable to EKN pursuant to any
                    EKN Guarantee for such Advance, notify each Lender when such
                    payment is made and promptly provide a copy of such EKN
                    Guaranty upon receipt by the Administrative Agent; and

     (b)  promptly provide (prior to an Event of Default) to the Borrower and
          (at all times) to each Lender copies of any:

          (i)  application referred to in clause (a)(A); and

          (ii) correspondence in which EKN takes or threatens to take any action
               referred to in Section 4.2, so long as it is permitted by
               Applicable Law and not prohibited from doing so by EKN.

SECTION 4.2   INVALIDITY OR IMPAIRMENT OF EKN DOCUMENTS.

Subject to Sections 4.3, 4.4 and 4.5, if:

     (a)  EKN unequivocally repudiates the EKN Undertaking or any of the EKN
          Guarantees or does or causes to be done any act or thing evidencing in
          writing that it unequivocally intends to repudiate the EKN Undertaking
          or any of the EKN Guarantees; or

     (b)  at any time any act, condition or thing required to be done, fulfilled
          or performed in order:

                                       39
<PAGE>

          (i)  to enable EKN lawfully to enter into, exercise its rights under
               and perform the obligations expressed to be assumed by it in the
               EKN Undertaking or any of the EKN Guarantees; or

          (ii) to ensure that the obligations expressed to be assumed by EKN in
               the EKN Undertaking or any of the EKN Guarantees are legal, valid
               and binding; or

         (iii) to make any EKN Document admissible in evidence in any relevant
               jurisdiction,

          is not done, fulfilled or performed or any authorization required in
          connection therewith is withdrawn or revoked; or

     (c)  the EKN Undertaking or any of the EKN Guarantees is declared void or
          voidable or is otherwise no longer binding upon and enforceable
          against EKN; or

     (d)  at any time it is or becomes unlawful for EKN to perform or comply
          with any or all of its obligations under the EKN Undertaking or any of
          the EKN Guarantees or any of the obligations of EKN under the EKN
          Undertaking or any of the EKN Guarantees are not or cease to be legal,
          valid and binding; or

     (e)  EKN ceases to be owned by the Kingdom of Sweden or any material
          adverse change occurs in the business, financial condition or assets
          of EKN which has or might, in the reasonable opinion of the
          Administrative Agent (acting on the instructions of the Required
          Lenders) be expected to have the result that EKN may not, or will be
          unable to, perform the EKN Undertaking or any of the EKN Guarantees;
          or

     (f)  the relevant authorities in the Kingdom of Sweden take any action
          which materially restricts the ability of EKN to meet its payment
          obligations under the EKN Undertaking or any of the EKN Guarantees at
          the time and in the currency in which they are due; or

     (g)  EKN ceases to carry on the business it carries on at the date hereof
          and, as a result, its ability to perform its material obligations
          under the EKN Undertaking or any of the EKN Guarantees or the EKN
          Undertaking or any of the EKN Guarantees is reasonably likely to be
          materially adversely affected; or

     (h)  EKN fails to execute and deliver to the Administrative Agent on behalf
          of the Lenders an EKN Guarantee in favor of the Lenders for any
          Advance made; or

     (i)  any EKN Guarantee ceases for any reason to secure the obligations of
          the Borrower hereunder (including as a result of the expiry of such
          EKN Guarantee),

then the Administrative Agent may (and, if so instructed by the Required Lenders
shall) give notice of such event to the Borrower in writing and the Borrower
shall prepay the Advances in full, together with accrued and unpaid interest
thereon and all other amounts then due and payable by the Borrower

                                       40

hereunder or under any Loan Document within ninety days (in the case of an EKN
Guarantee) or 180 days (in the case of the EKN Undertaking) of the receipt of
such notice.


SECTION 4.3   PARTIAL UNAVAILABILITY OF EKN GUARANTEE

Subject to Section 4.4 if:

     (a)  any EKN Guarantee (the "Affected EKN Guarantee") is affected by any of
                                  ----------------------
          the circumstances referred to in clauses (a) through (i) of Section
          4.2; and


     (b)  the aggregate amount of Indebtedness hereunder which is (or would be
          but for any of the circumstances referred to in Section 4.2 or is
          intended to be) guaranteed by EKN pursuant to such Affected EKN
          Guarantee (individually or in aggregate with all other EKN Guarantees
          which have been affected by the circumstances referred to in Section
          4.2) is less than $16,000,000,


the Administrative Agent shall only be entitled to make demand pursuant to
Section 4.2 and the Borrower shall only be obliged to prepay an amount equal to
the Advance intended to be guaranteed by EKN pursuant to the Affected EKN
Guarantee.

SECTION 4.4   SUBSTITUTE GUARANTOR.

If any EKN Guarantee is affected by any of the circumstances referred to in
clauses (a) through (i) of Section 4.2, the Borrower may (with the consent of
the Administrative Agent, acting on the instructions of the Required Lenders,
which consent may be withheld in the absolute discretion of the Required
Lenders) procure from a guarantor of equivalent status to EKN (as at the date
hereof) to deliver to the Administrative Agent a guaranty and indemnity in form
and substance satisfactory to the Administrative Agent, which shall only be
accepted by the Lenders on terms and conditions which are satisfactory to the
Required Lenders, which guaranty and indemnity shall be accepted by the
Administrative Agent as a substitute for the relevant Affected EKN Guarantee.

SECTION 4.5   UNAVAILABILITY OF EKN UNDERTAKING.


If the EKN Undertaking is affected by any of the circumstances referred to in
clauses (a), (b), (c), (d), (e), (f) or (g) of Section 4.2, the Administrative
Agent shall only be entitled to make demand pursuant to Section 4.2 if, at the
time of the occurrence of the relevant circumstances the amount of the undrawn
Total Commitments is greater than $16,000,000 and such undrawn Commitments when
drawn will not be guaranteed by EKN as a result of such circumstances.


               ARTICLE 5.  REPAYMENT AND PREPAYMENT OF THE ADVANCES

SECTION 5.1   REPAYMENT.

     (a)  Save as otherwise provided herein, the Borrower shall repay the
          Advances such that the Advances are on the First Principal Payment
          Date and on the last day of each six



                                       41
<PAGE>


          monthly period thereafter reduced by an amount equal to 10% of the
          aggregate amount of Advances outstanding immediately after the
          Termination Date.

     (b)  On the Maturity Date, the Borrower shall repay the aggregate then-
          outstanding principal amount of the Advances, together with any and
          all accrued and unpaid interest thereon and all other amounts due and
          owing hereunder and under the other Loan Documents.

SECTION 5.2   MANDATORY PREPAYMENT OF ADVANCES.

     (a)  No later than three Business Days after its receipt of any Net Cash
          Proceeds referred to in clause (i) below, the Borrower shall (if
          required by the Administrative Agent (acting on the instructions of
          the Required Lenders)) prepay Advances in an aggregate principal
          amount equal to:

          (i)  the Net Cash Proceeds from the direct or indirect sale or
               disposition of any Property of the Borrower and/or any of its
               Subsidiaries (other than any sale of inventory and other goods in
               the ordinary course of business or any disposition by way of an
               FCC License Transfer or an FCC License Partition permitted under
               Section 9.1(f)(iii)) that is otherwise permitted under this
               Agreement during any calendar year, to the extent such aggregate
               Net Cash Proceeds received during such calendar year shall exceed
               $5,000,000 multiplied by

          (ii) a fraction, (A) the numerator of which is the aggregate principal
               amount of the Advances outstanding at the time of such sale or
               disposition, and (B) the denominator of which is such aggregate
               principal amount, plus the aggregate principal amount of all
               loans or advances outstanding at the time of such sale or
               disposition under the Ericsson Loan Agreement and any other
               Permitted Loan Agreements (the loans under which are required to
               be prepaid with such Net Cash Proceeds), to the extent the
               Intercreditor Agreement permits such prepayment.

     (b)  If:

          (i)  at any time after the occurrence of any FCC License Transfer or
               FCC License Partition any Indebtedness under any Permitted Loan
               Agreement is required to be prepaid, the Borrower wishes to make
               any Distribution (other than a Distribution permitted under
               Section 9.1(e)(iv)) in respect of its Stock or any Indebtedness
               owing to the Parent or any Affiliate thereof (other than the
               Borrower and its Subsidiaries), the Borrower will notify the
               Administrative Agent of its intention to make such Distribution
               at least 10 Business Days prior to the proposed date of such
               Distribution;

          (ii) the Required Lenders shall so require and if the Borrower shall
               make such Distribution by the proposed date of such Distribution,
               then the Borrower



                                       42
<PAGE>

               shall prepay the then-outstanding Advances within five Business
               Days after receipt of notice of such requirement from the
               Administrative Agent in an aggregate principal amount equal to
               the same proportion of the Lenders' Portion of Excess Proceeds in
               respect of such sale or assignment as such Distribution bore to
               the Parent's Portion of Excess Proceeds in respect of such sale
               or assignment, until such time as an aggregate amount equal to
               the Excess Proceeds in respect of such sale or assignment shall
               have been paid to the Lenders, other providers of vendor
               financing to the Borrower and its Subsidiaries and the Parent.

     (c)  Any prepayment pursuant to clauses (a) or (b) shall not reduce the
          principal amount of Advances required to be repaid on any date
          pursuant to Section 5.1(a), to the extent that such Advances are
          outstanding on such date.

     (d)  No prior prepayment of Advances shall reduce the principal amount of
          the Advances required to be prepaid pursuant to clauses (a) or (b).

     (e)  The Borrower shall prepay all outstanding Advances, and the Lenders'
          Commitments hereunder shall terminate, upon the termination of the
          Equipment Acquisition Agreement as a result of a default thereunder by
          the Borrower or its Subsidiaries.

     (f)  Unless the Lenders shall consent otherwise, if on any date the
          Borrower makes an optional prepayment of any loan outstanding under a
          Permitted Loan Agreement (other than the prepayment of Tranche Y of
          the Ericsson Loan Agreement in Common Stock of the Grandparent or the
          refinance of all or a portion of Tranche X of the Ericsson Loan
          Agreement pursuant to a Permitted Loan Agreement) for any reason, the
          Borrower shall prepay Advances in an aggregate principal amount equal
          to:

          (i)  such prepayment of the loan, multiplied by

          (ii) a fraction, (A) the numerator of which is the aggregate principal
               amount of the Advances outstanding at the time of such
               prepayment, and (B) the denominator of which is such aggregate
               principal amount, plus the aggregate principal amount of all
               loans outstanding under the Permitted Loan Agreements immediately
               prior to such prepayment.

     (g)  Any prepayment pursuant to this Section 5.2 shall:

          (i)  be applied to the prepayment of a ratable aggregate principal
               amount of such Advances as the Borrower shall specify, and shall
               be inversely applied to the ratable reduction of the amounts by
               which the Advances are required to be repaid on any date pursuant
               to Section 5.1(a); and

          (ii) not reduce the principal amount of the Advances required to be
               prepaid pursuant to this Section 5.2.

                                       43
<PAGE>

SECTION 5.3   OPTIONAL PREPAYMENTS OF ADVANCES.

     (a)  Subject to the terms of the Intercreditor Agreement, the Borrower may,
          except as provided below, upon at least five Business Days' notice to
          the Administrative Agent (which notice shall be irrevocable), stating
          the proposed prepayment date and the aggregate principal amount of the
          Advances to be prepaid, and if such notice is given the Borrower
          shall, except as otherwise provided in this Section 5.3, prepay such
          outstanding principal amount of the Advances so specified in whole or
          ratably in part.

     (b)  Any prepayment pursuant to clause (a):

          (i)  of less than the entire aggregate principal amount of the
               Advances then outstanding shall be applied to the prepayment of a
               ratable aggregate principal amount of Advances; and

          (ii) shall be applied in inverse order of maturity to the reduction of
               the amounts by which such Advances are required to be repaid
               pursuant to Section 5.1(a) and shall be in minimum of $5,000,000
               and integral multiples of $1,000,000 in excess thereof (or, if
               less, the remaining outstanding balance of all Advances).

SECTION 5.4   REBORROWINGS.

Any amount prepaid or repaid pursuant to this Agreement may not be reborrowed.

           ARTICLE 6.  ILLEGALITY, INCREASED COSTS AND CAPITAL ADEQUACY

SECTION 6.1   ILLEGALITY.

Notwithstanding any other provisions herein:

     (a)  if any present or future Applicable Law shall make it unlawful for any
          Lender to make or maintain its participation in an Advance, such
          Lender shall forthwith give notice of such circumstances to the
          Borrower, the Administrative Agent and the other Lenders and thereupon
          the Commitment of such Lender to participate in making any further
          Advance shall forthwith be suspended until such notifying Lender shall
          have notified the Administrative Agent and the Borrower that the
          circumstance giving rise to such determination no longer exists (and
          if such notifying Lender shall determine that such circumstance no
          longer exists it shall so notify the Administrative Agent and the
          Borrower promptly after determining the same); and

     (b)  such Lender will designate a different Lending Office if such
          designation will avoid the need for any suspension described in the
          preceding sentence and will not, in the opinion of such Lender, be
          otherwise disadvantageous to such Lender.

                                       44
<PAGE>

SECTION 6.2   ADDITIONAL COSTS AND CAPITAL ADEQUACY.

     (a)  If any Applicable Law shall:

          (i)  impose or increase or render applicable (other than to the extent
               specifically provided for elsewhere in this Agreement) any
               special-deposit, reserve (including any reserve percentage under
               the regulations issued from time to time by the Board of
               Governors of the Federal Reserve System for determining the
               maximum reserve requirement (including any emergency,
               supplemental or other marginal reserve requirement) for a member
               bank of the Federal Reserve System in New York City with respect
               to liabilities or assets consisting of or including Eurocurrency
               Liabilities (as defined in such regulations) (or, with respect to
               any other category of liabilities that includes deposits by
               reference to which the interest rate on the Advances is
               determined)), assessment, liquidity, capital adequacy or other
               similar requirements (whether or not having the force of law)
               against assets held by, or deposits in or for the account of, or
               loans by, or commitments of an office of any Lender; or

          (ii) impose on any Lender or the Administrative Agent any other
               conditions or requirements with respect to this Agreement, the
               other Loan Documents, such Lender's Commitment, or any class of
               loans, or commitments of which any of the Advances or such
               Lender's Commitment form a part,

          and the result of any of the foregoing is to increase the cost to such
          Lender or any corporation controlling such Lender of making, funding,
          issuing, renewing, extending or maintaining its participation in any
          of the Advances or such Lender's Commitment (taking into account such
          Lender's or such corporation's then-existing policies with respect to
          maintaining capital), then the Borrower shall pay to the
          Administrative Agent for the account of such Lender, within 15 days
          after demand from time to time as specified by such Lender, additional
          amounts sufficient to compensate such Lender or such corporation in
          the light of such circumstances, for such increased costs.

     (b)  If any Applicable Law, that becomes effective after the date hereof,
          affects the amount of capital required or expected to be maintained by
          any Lender or any corporation controlling such Lender and such Lender
          or such corporation determines that the amount of capital required to
          be maintained by it is increased by or based upon the existence of
          such Lender's Commitment with respect to any Advances, the Borrower
          will pay to such Lender, within 15 days after demand from time to time
          as specified by such Lender, additional amounts sufficient to
          compensate such Lender or such corporation in the light of such
          circumstances, to the extent that such Lender reasonably determines
          such increase in capital to be allocable to the existence of such
          Lender's commitment to lend hereunder.

                                       45
<PAGE>

     (c)  Each demand by a Lender pursuant to this Section 6.2 shall be
          accompanied by a statement setting forth in reasonable detail the
          basis for such demand and the computation of such amount, including
          any method by which such cost was allocated to the Borrower.  In
          determining the amount of any compensation, such Lender may use any
          reasonable averaging or attribution methods set forth in such demand,
          and any such methods so used shall be binding on the Borrower.  The
          amount specified in any such demand shall be conclusive evidence of
          the amount owing, absent manifest error.  Such Lender will designate a
          different Lending Office if such designation will avoid the need for
          or reduce the amount of any compensation under this Section 6.2 and
          will not, in the judgment of such Lender, be otherwise disadvantageous
          to such Lender.  By making any payment under this Section 6.2, the
          Borrower is not waiving its right to contest that the amounts set
          forth in the certificates are based on manifest error.

SECTION 6.3   TAXES.

The Borrower shall:

     (a)  make any and all payments hereunder and under any other Loan Document
          (which shall, for the avoidance of doubt, include the payment of fees
          referred to in Section 3.1) free and clear of and without deduction or
          withholding for any Taxes;

     (b)  if required by Applicable Law to deduct or withhold any Taxes or Other
          Taxes from or in respect of any sum payable hereunder and under any
          other Loan Document to any Lender or the Administrative Agent:

          (i)  increase the sum payable as may be necessary so that after making
               all required deductions or withholdings (including deductions or
               withholdings applicable to additional sums payable under this
               Section 6.3) such Lender or the Administrative Agent (as the case
               may be) receives an amount equal to the sum it would have
               received had no such deductions or withholdings been made;

          (ii) make such deductions and withholdings; and

         (iii) pay the full amount deducted or withheld to the relevant taxation
               authority or other authority in accordance with applicable law;

     (c)  pay any Other Taxes;

     (d)  indemnify each Lender and the Administrative Agent for the full amount
          of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by
          any jurisdiction on amounts payable under this Section 6.3) paid by
          such Lender or the Administrative Agent (as the case may be), and any
          liability (including penalties, interest and expenses) arising
          therefrom or with respect thereto, which indemnification shall be

                                       46
<PAGE>

          made within 15 days from the date such Lender or the Administrative
          Agent (as the case may be) makes written demand therefor;

     (e)  within 30 days after the date of any payment of Taxes or Other Taxes
          furnish to the Administrative Agent the original or a certified copy
          of a receipt evidencing payment thereof; and

     (f)  in the case of any payment hereunder or under any other Loan Document
          by or on behalf of the Borrower through an account or branch outside
          the United States or on behalf of the Borrower by a payor that is not
          a United States person, if the Borrower determines that no Taxes are
          payable in respect thereof, furnish, or cause such payor to furnish,
          to the Administrative Agent, at such address, an opinion of counsel
          acceptable to the Administrative Agent stating that such payment is
          exempt from Taxes.  (For purposes of this clause (f) and Section 6.4
          below, the terms "United States" and "United States person" shall have
                            -------------       --------------------
          the meanings specified in Section 7701 of the IRC.)

SECTION 6.4   TAX FORMS.

     (a)  Each Lender organized under the laws of a jurisdiction outside the
          United States, on or prior to the date of its execution and delivery
          of this Agreement in the case of each initial Lender and on the date
          of the Assignment and Acceptance pursuant to which it becomes a Lender
          in the case of each other Lender, and from time to time thereafter if
          requested in writing by the Borrower (but only so long as such Lender
          remains lawfully able to do so), shall provide the Borrower with
          Internal Revenue Service Form 1001 or 4224, as appropriate, or any
          successor or other form prescribed by the Internal Revenue Service,
          certifying that such Lender is exempt from or entitled to a reduced
          rate of United States withholding tax on payments of interest pursuant
          to this Agreement.  If the form provided by a Lender at the time such
          Lender first becomes a party to this Agreement indicates a United
          States interest withholding tax rate in excess of zero, withholding
          tax at such rate shall be considered excluded from "Taxes" as defined
          hereunder.  If any form or document referred to in this subsection (a)
          requires the disclosure of information, other than information
          necessary to compute the tax payable and information required on the
          date hereof by Internal Revenue Service form 1001 or 4224, that the
          Lender reasonably considers to be confidential, the Lender shall give
          notice thereof to the Borrower and shall not be obligated to include
          in such form or document such confidential information.

     (b)  For any period with respect to which a Lender has failed to provide
          the Borrower with the appropriate form described in Section 6.4(a)
          (other than if such failure is due to a change in law occurring
          ------ ----
          subsequent to the date on which a form originally was required to be
          provided, or if such form otherwise is not required under the first
          sentence of clause (a) above), such Lender shall not be entitled to
          indemnification under Section 6.3 with respect to Taxes imposed by the
          United States; provided that should a Lender become subject to Taxes
                         --------
          because of its failure to deliver a form required hereunder, the
          Borrower shall take such steps as such Lender shall

                                       47
<PAGE>

          reasonably request and at such Lender's expense to assist such Lender
          to recover such Taxes.

     (c)  If the Borrower is required to pay any amounts to or for the account
          of any Lender pursuant to Section 6.3, such Lender will designate a
          different Lending Office if such designation will avoid the need for
          or reduce the amount of any such payment and will not, in the judgment
          of such Lender, be otherwise disadvantageous to such Lender.

SECTION 6.5   SURVIVAL.

Without prejudice to the survival of any other agreement of the Borrower
hereunder, the agreements and obligations of the Borrower contained in this
Article 6 shall survive the payment in full of principal and interest hereunder.

     (t)  DISCLOSURE:  this Agreement and the statements and documents referred
          to herein or delivered to the Administrative Agent, the Arranger

               restriction which, in the opinion of the management of the
               Borrower, is so unusual or burdensome, in the context of its
               business, as in the foreseeable future might materially and

               such Loan Party, or the ability of such Loan Party to perform the
               obligations to be performed by it under the Loan Documents to

               meet the provisions of federal or state statutes, orders, rules
               or regulations will be so burdensome as to affect or impair, in a
               materially adverse manner, the business or condition, financial
               or otherwise, of the Borrower or any of its Subsidiaries;

               transactions.  The Borrower and each of its Subsidiaries has made
               all required contributions to each Employee Benefit Plan and each
               Multiemployer Plan.  To the extent applicable, the Borrower has

               benefit plan within the meaning of Section 3(1) or Section

               (except as required by Title I, Subtitle B, Part 6 of ERISA);

        (iii)  the Borrower, each of its Subsidiaries and each ERISA Affiliate
               may terminate each such Plan at any time (or at any time
               subsequent to the expiration of any applicable bargaining
               agreement) in the discretion of such Loan Party or such ERISA
               Affiliate without liability to any Person;

         (iv)  each contribution required to be made to a Guaranteed Pension
               Plan, whether required to be made to avoid the incurrence of an
               accumulated funding deficiency, the notice or lien provisions of
               Section 302(f) of ERISA, or otherwise, has been timely made;

          (v)  no waiver of minimum funding standards or extension of
               amortization periods has been requested or received with respect
               to any Guaranteed Pension Plan;

         (vi)  no liability to the PBGC (other than required insurance premiums,
               all of which have been paid) has been incurred by the Borrower,
               any of its Subsidiaries or any ERISA Affiliate with respect to
               any Guaranteed Pension Plan and there has not been any ERISA
               Event, or any other event or condition that presents a material
               risk of termination of any Guaranteed Pension Plan by the PBGC.
               None of the Borrower, any of its Subsidiaries or any ERISA
               Affiliate has instituted or intends to institute proceedings to
               terminate a Guaranteed Pension Plan;

        (vii)  no event requiring notice to the PBGC under Section 302(f)(4)(A)
               of ERISA has occurred with respect to any Guaranteed Pension Plan
               and no amendment with respect to which security is required under
               Section 307 of ERISA has been made or is reasonably expected to
               be made to any Guaranteed Pension Plan;

       (viii)  based on the latest valuation of each Guaranteed Pension Plan
               (which in each case occurred within 12 months prior to the date
               of this representation), and on the actuarial methods and
               assumptions employed for that valuation, the aggregate benefit
               liabilities of all such Guaranteed Pension Plans within the
               meaning of Section 4001 of ERISA did not exceed the aggregate
               value of the assets of all such Guaranteed Pension Plans,
               disregarding for this purpose the benefit liabilities and assets
               of any Guaranteed Pension Plan with assets in excess of benefit
               liabilities;

         (ix)  none of the Borrower, any of its Subsidiaries or any ERISA
               Affiliate has incurred or expects to incur any material liability
               (including secondary liability) to any Multiemployer Plan as a
               result of a complete or partial withdrawal from such
               Multiemployer Plan under Section 4201 of ERISA or as a result of
               a sale of assets described in Section 4204 of ERISA. Neither any
               Loan Party nor any ERISA Affiliate has been notified that any
               Multiemployer Plan is in reorganization or insolvent under and
               within the meaning of Section 4241 or Section 4245 of ERISA or
               that any Multiemployer Plan intends to terminate or has been
               terminated under Section 4041A of ERISA;

     (aa) REGULATIONS U AND X:  no portion of any Advance shall be used or
          obtained for the purpose of purchasing or carrying any "margin

not, or permit any of its Subsidiaries to:

     (a)  RESTRICTIONS ON INDEBTEDNESS:

          (i)  create, incur, assume, guarantee or suffer to exist, contingently
               or otherwise, any Indebtedness other than (without duplication)
               Permitted Indebtedness; and

               Subordinated Indebtedness owing to the Grandparent or any of its
               Subsidiaries) would exceed $35.00, multiplied by the aggregate
               POPs of all Permitted BTAs as of such date (excluding any POPs in
               geographic areas for which the right to provide PCS services
               shall have been sold pursuant to FCC License Partitions on or
               before such date), and


          for the purposes of determining compliance with this Section 9.1(a),
          in the event that an item of Indebtedness meets the criteria of more
          than one of the types of Permitted Indebtedness described in the

               other security interest of any kind other than Permitted Liens
               upon any of its Property or assets of any character whether now
               owned or hereafter acquired, or upon the income or profits
               therefrom;

         (ii)  other than Permitted Liens, transfer any of such Property or
               assets or the income or profits therefrom for the purpose of
               subjecting the same to the payment of Indebtedness or performance
               of any other obligation in priority to payment of its general
               creditors;

               to acquire, any property or assets upon conditional sale or other
               title-retention or purchase-money security agreement, device or

          such action from the Required Lenders.

SECTION 13.2   ADMINISTRATIVE AGENT'S RELIANCE, ETC.

Neither the Administrative Agent nor any of its directors, officers, agents or
employees shall be liable for any action taken or omitted to be taken by it or
them under or in connection with the Loan Documents, except for its or their own

          therefrom until the Administrative Agent receives and accepts an
          Assignment and Acceptance entered into by such Lender, as assignor,
          and an assignee, as provided in Section 14.9;

     (b)  may consult with legal counsel (including counsel for any Loan Party),
          independent public accountants and other experts selected by it and

          accountants or experts;

     (c)  makes no warranty or representation to any Lender and shall not be

     (d)  shall not have any duty to ascertain or to inquire as to the
          performance or observance of any of the terms, covenants or conditions
          of any Loan Document on the part of any Loan Party or to inspect the
          property (including the books and records) of any Loan Party;

     (e)  shall not be responsible to any Lender for the due execution,
          legality, validity, enforceability, genuineness, sufficiency or value
          of, or the perfection or priority of any lien or security interest
          created or purported to be created under or in connection with, any
          Loan Document or any other instrument or document furnished pursuant
          thereto;

     (f)  shall incur no liability under or in respect of any Loan Document by
          acting upon any notice, consent, certificate (including any
          Disbursement Claim) or other instrument or writing (which may be by
          telegram, telecopy, cable or telex) believed by it to be genuine and
          signed or sent by the proper party or parties;

     (g)  shall incur no liability as a result of any determination whether the
          transactions contemplated by the Loan Documents constitute a "highly
          leveraged transaction" within the meaning of the interpretations
          issued by the Comptroller of the Currency,

          (x)  assume that:

          (i)  any representation and/or warranty made by any Loan Party in

               a Lender or the Borrower clearly stating that such event exists;
               and

        (iii)  no Loan Party is in breach of or in default under its obligations
               under this Agreement or any other Loan Document, unless it has
               actual knowledge or actual notice to the contrary;

         (iv)  assume that the Lending Office of each Lender is that identified

               becomes a Lender after the date hereof, at the end of the
               Assignment and Acceptance under which it first became a Lender)
               until it has received from such Lender a notice designating some
               other office of such Lender to replace its Lending Office and act
               upon any such notice until the same is superseded by a further
               such notice; and

          (y)  rely upon

               (i) as to any matters of fact which might reasonably be expected
                   to be within the knowledge of any Loan Party, as the case may
                   be, a certificate signed by an Authorized Officer for the
                   time being on behalf of such Loan Party;

              (ii) any communication or document believed by it to be genuine
                   and correct.

SECTION 13.3   OBLIGATIONS OF ADMINISTRATIVE AGENT.

               Loan Party or Ericsson in connection with this Agreement or any
               other Loan Document or the transactions contemplated thereby
               (including in a Disbursement Claim) is true or any information

          person on behalf of either of the parties thereto; and

     (b)  any notice purporting to be duly signed by the persons giving such
          notice as having been duly signed by such persons,

and the Administrative Agent shall not be bound in any such case to ask for
further evidence of authority or otherwise or be responsible for any loss that
may be occasioned by its failing to do so.

SECTION 13.12   DELEGATION.

The Administrative Agent may, in the execution and exercise of all or any of the
powers, authorities and discretions vested in it by this Agreement or any Loan
Document act by responsible officers or a responsible officer for the time being
of the Administrative Agent and the Administrative Agent may also, whenever it
thinks fit, whether by power of attorney or otherwise, delegate to any person or
persons all or any of the powers, authorities and discretions vested in it by
this Agreement or any such delegation may be made upon such terms and conditions
and subject to such regulations (including power to sub-delegate with the
consent of the Administrative Agent) as the Administrative Agent may think fit
in the interests of the Lenders and provided that the Administrative Agent shall
have exercised reasonable care in the selection of such delegate, it shall not
in any way or to any extent be responsible for any loss incurred by any
misconduct or default on the part of such delegate or sub-

delegate.  The Administrative Agent shall give prompt notice to the Borrower and
the Lenders of the appointment of any delegate as aforesaid and shall procure
that any delegate shall also give prompt notice to the Borrower and the Lenders
of any sub-delegate.

SECTION 13.13   REPRESENTATION BY LENDER.

Each Lender represents and warrants in favor of the Administrative Agent that
either:

     (a)  it is not resident for tax purposes in the United Kingdom and is
          beneficially entitled to receive its portion of any Advance and the
          interest thereon; or

     (b)  it is a bank as defined for the purposes of Section 840A of the Income
          and Corporation Taxes Act 1988 and is beneficially entitled to receive
          its portion of any Advance and the interest thereon,

and each Lender agrees in favor of the Administrative Agent to notify the Agent
if there is any change in its position from that set out above.

SECTION 13.14   FAILURE BY LENDER TO MAKE ADVANCE.

     (a)  Unless the Administrative Agent shall have received notice from a
          Lender prior to 9.00am on the Business Day prior to any Disbursement
          Date that such Lender will not make available to the Administrative
          Agent such Lender's Commitment Percentage of the Advance to be made on
          such Disbursement Date, the Administrative Agent may assume that such
          Lender has made such Commitment Percentage of the Advance available to
          the Administrative Agent on the date of such Advance in accordance
          with Section 2.5 and the Administrative Agent may, in reliance upon
          such assumption, make available to the Borrower on such date a
          corresponding amount.

     (b)  If and to the extent that such Lender shall not have so made such
          Commitment Percentage of the Advance available to the Administrative
          Agent, such Lender and the Borrower severally agree to repay or pay to
          the Administrative Agent forthwith on demand such corresponding amount
          together with interest thereon, for each day from the date such amount
          is made available to the Borrower until the date such amount is repaid
          to the Administrative Agent, at an interest rate equal to the
          Administrative Agent's cost of funds for providing such amount to the
          Borrower from the date of making of the relevant Advance until receipt
          of such funds by the Administrative Agent.

     (c)  If such Lender shall repay to the Administrative Agent such
          corresponding amount, such amount so repaid shall constitute such
          Lender's Commitment Percentage of such Advance for the purposes of
          this Agreement.

SECTION 13.15   FAILURE OF BORROWER TO MAKE PAYMENT.

Unless the Administrative Agent shall have received notice from the Borrower
prior to the date on which any payment is due and owing to the Lenders hereunder
that the Borrower will not make such payment in full, the Administrative Agent
may assume that the Borrower has made such payment in full to the Administrative
Agent on such date and the Administrative Agent may, in reliance upon such
assumption, cause to be distributed to each Lender on such due date an amount
equal to the amount then due such Lender.  If and to the extent the Borrower
shall not have so made such payment in full to the Administrative Agent, each
Lender shall repay to the Administrative Agent forthwith on demand such amount
distributed to such Lender together with interest thereon, for each day from the
date such amount is distributed to such Lender until the date such Lender repays
such amount to the Administrative Agent, at the Federal Funds Rate.

          counsel and, with respect to the Collateral Agent, reasonable
          allocated costs and expenses of in-house counsel and legal staff) that
          may be incurred by or asserted or awarded against any Indemnified
          Party, in each case arising out of or in connection with:

               (A)  this Agreement and any other Loan Documents, any of the
                    transactions contemplated herein or therein or the actual or

          except to the extent such claim, damage, loss, liability or expense is
          found in a final, non-appealable judgment by a court of competent
          jurisdiction to have resulted from such Indemnified Party's gross
          negligence or willful misconduct.

     (b)  In the case of any investigation, litigation or other proceeding to
          which the indemnity in this Section 14.5(a) applies, the indemnity

          indirect, consequential or punitive damages arising out of or
          otherwise

                                      123
<PAGE>

          herein or the actual or proposed use of the proceeds of the Advances.

     (d)  If any payment of principal of any Advance is made by the Borrower to
          or for the account of a Lender other than on the last day of the
          Interest Period for such Advance, as a result of any repayment or,
          prepayment or acceleration of the maturity of the Advances pursuant to
          Section 12.1 or for any other reason, the Borrower shall pay to the
          Administrative Agent for the account of such Lender any loss, cost or
          expense (including loss of anticipated profit) that any Lender may
          sustain or incur as a consequence of the making of any payment of an
          Advance on a day that is not the last day of the applicable Interest
          Period with respect thereto.

     (e)  The Borrower shall indemnify each Lender against any loss, cost or
          expense incurred by any Lender as a result of any failure to fulfill

          and 11.1, including any loss (including loss of anticipated profits),

          of deposits or other funds acquired by such Lender to fund its
          participation in such requested Advance.

     (f)  Without prejudice to the survival of any other agreement of the
          Borrower hereunder, the agreements and obligations of the Borrower
          contained in this Section 14.5 shall survive the payment in full of
          principal and interest hereunder.

SECTION 14.6   RIGHT OF SET-OFF.

Upon (a) the occurrence and during the continuance of any Event of Default and
(b) the making of the request specified by Section 12.1 to authorize the
Administrative Agent to declare, or the Administrative Agent's declaration of,
the Advances to be due and payable pursuant to the provisions of Section 12.1,
each Lender and each of its Affiliates is authorized at any time and from time
to time, to the fullest extent permitted by law, to set off and otherwise apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender or such
Affiliate to or for the credit or the account of the Borrower against any and
all of the obligations of the Borrower now or hereafter existing under this
Agreement, irrespective of whether such Lender shall have made any demand under
this Agreement and although such obligations may be unmatured.  Each Lender
agrees promptly to notify the Administrative Agent and the Borrower after any
such set-off and application; provided that the failure to give such notice
                              --------
shall not affect the validity of such set-off and application.  The rights of
each Lender and its Affiliates under this Section 14.6 are in addition to other
rights and remedies (including other rights of set-off) that such Lender and its
Affiliates may have.

SECTION 14.7   SHARING OF PAYMENTS, ETC.

     (a)  Subject to clause (b), if:

                                      124
<PAGE>

          (i)  any Lender shall obtain any payment (whether voluntary,
               involuntary, through the exercise of any right of set-off, or
               otherwise) on account of the Advances owing to it (other than
               pursuant to Section 6.2, 6.3 or 14.7(b)) in excess of its ratable
               share of payments on account of the Advances obtained by all the
               Lenders, such Lender shall forthwith purchase from the other
               Lenders such participations in the Advances owing to them as
               shall be necessary to cause such purchasing Lender to share the
               excess payment ratably with each of them;

         (ii)  all or any portion of an excess payment referred to in clause (b)
               is thereafter recovered from such purchasing Lender, such
               purchase from each Lender shall be rescinded and such Lender
               shall repay to the purchasing Lender the purchase price to the
               extent of such recovery together with an amount equal to such
               Lender's ratable share (according to the proportion of (A) the
               amount of such Lender's required repayment to (B) the total
               amount so recovered from the purchasing Lender) of any interest
               or other amount paid or payable by the purchasing Lender in
               respect of the total amount so recovered.

     (b)  The Borrower agrees that any Lender purchasing a participation
          pursuant to paragraph (a) from another Lender pursuant to this Section
          14.7 may, to the fullest extent permitted by law, exercise all its
          rights of payment (including the right of set-off) with respect to
          such participation as fully as if such Lender were the direct creditor
          of the Borrower in the amount of such participation.

                        --------

          (i)  each such assignment of any Commitments shall be of a uniform,
               and not a varying, percentage of all rights and obligations under
               and in respect of all Commitments;

         (ii)  except in the case of an assignment to a Person that, immediately

        (iii)  the parties to each such assignment shall:

               (A)  execute and deliver to the Administrative Agent, for its
                    acceptance and recording in the Register, an Assignment and

                    of $2,500; and

               (B)  deliver a copy of such Assignment and Acceptance to the
                    Borrower at the time it delivers a copy to the
                    Administrative Agent; and

         (iv)  unless the Borrower shall have consented thereto, no such
               assignment of undrawn Commitments shall be made:

               (A)  except to a Person that shall have represented that it has a
                    combined capital and surplus in excess of $50,000,000; and

          after the effective date specified in such Assignment and Acceptance:

          (i)  the assignee thereunder shall be a party hereto and, to the
               extent that rights and obligations hereunder and under the
               Intercreditor Agreement have been assigned to it pursuant to such

               Lender hereunder and thereunder; and

          (ii) the Lender assignor thereunder shall, to the extent that rights

<PAGE>

               Agreement and the Intercreditor Agreement (and, in the case of an
               Assignment and Acceptance covering all or the remaining portion
               of an assigning Lender's rights and obligations under this
               Agreement, such Lender shall cease to be a party hereto).

               sufficiency or value of this Agreement or any other  instrument
               or document furnished pursuant hereto;

         (ii)  such assigning Lender makes no representation or warranty and
               assumes no responsibility with respect to the financial condition
               of the Borrower or the performance or observance by the Borrower
               of any of its obligations under this Agreement or any other
               instrument or document furnished pursuant hereto;

        (iii)  such assignee confirms that it has received a copy of this
               Agreement, the Intercreditor Agreement and each other Loan
               Document, together with copies of the financial statements
               referred to in Section 10.1(bb) and such other documents and
               information as it has deemed appropriate to make its own credit
               analysis and decision to enter into such Assignment and
               Acceptance;

         (iv)  such assignee will, independently and without reliance upon the
               Administrative Agent or the Arranger, such assigning Lender or
               any other Lender and based on such documents and information as
               it shall deem appropriate at the time, continue to make its own
               credit decisions in taking or not taking action under this
               Agreement;

          (v)  such assignee appoints and authorizes the Administrative Agent to
               take such action as agent on its behalf and to exercise such
               powers and discretion under this Agreement as are delegated to
               the Administrative Agent by the terms hereof, together with such
               powers and discretion as are reasonably incidental thereto;

         (vi)  such assignee agrees that it will perform in accordance with
               their terms all of the obligations that by the terms of this
               Agreement and the Intercreditor Agreement are required to be
               performed by it as a Lender;

                                      127
<PAGE>

        (vii)  such assignee makes the representations set forth in subsection
               (a)(iv) above and in Section 13.13; and

       (viii)  such assignee confirms that it is bound by the confidentiality
               provisions set forth in Section 14.14.

     (d)  The Administrative Agent shall maintain at its address referred to in

          accepted by it and a register for the recordation of the names and
          addresses of the Lenders and the Commitments of, and portions of the
          principal amount of the Advances owing to, each Lender from time to
          time (the "Register").  The entries in the Register shall be
                     --------
          conclusive and binding for all purposes, absent manifest error, and
          the Borrower, the Administrative Agent and the Lenders may treat each
          Person whose name is recorded in the Register as a Lender hereunder
          for all purposes of this Agreement.  The Register shall be available
          for inspection by the Borrower or any Lender at any reasonable time
          and from time to time upon reasonable prior notice.

     (e)  Upon its receipt of an Assignment and Acceptance executed by an
          assigning Lender and an assignee, the Administrative Agent shall, if
          such Assignment and Acceptance has been completed and is substantially
          in the form of Exhibit C,
                         ---------

          (i)  accept such Assignment and Acceptance;

         (ii)  record the information contained therein in the Register; and

        (iii)  give prompt notice thereof to the Borrower.

     (f)  Any Lender may, in connection with any assignment or proposed
          assignment pursuant to this Section 14.9, disclose to the assignee or
          participant or proposed assignee or participant, any information
          relating to the Borrower furnished to such Lender by or on behalf of
          the Borrower; provided that, prior to any such disclosure, the
                        --------
          assignee or participant or proposed assignee or participant shall
          agree to preserve the confidentiality of any Confidential Information
          received by it from such Lender.

     (g)  Notwithstanding any other provision set forth in this Agreement, any
          Lender may at any time create a security interest in all or any
          portion of its rights under this Agreement (including its Commitment
          Percentage in the Advances) in favor of any Federal Reserve Bank in
          accordance with Regulation A of the Board of Governors of the Federal
          Reserve System.

     (h)  Notwithstanding any other provision set forth in this Agreement, any
          Lender may at any time assign all or a portion of its rights and
          obligations hereunder to EKN in accordance with the EKN Documents.

SECTION 14.10   INDEPENDENCE OF THE AGREEMENT.

The Borrower expressly acknowledges that this Agreement constitutes an
obligation on the Borrower's part that is independent and completely separate
from the Equipment Acquisition Agreement and any other supply agreement.  The
liability of the Borrower to effect payment of the principal amount and interest
on any Advance and of any other amount to be paid under this Agreement on the
due dates therefor, shall not be conditional upon performance by Ericsson or any
cooperation party of the terms of the Equipment Acquisition Agreement or any
other supply agreement or any related contract and shall not be affected in any
way by any claim which the Borrower may have or might consider that it has
against Ericsson or any cooperating party as aforesaid or by any other reason
whatsoever.

SECTION 14.11   OBLIGATIONS SEVERAL.

The obligations of the Lenders hereunder are several and not joint, and the
failure of any Lender to participate in the making of any Advance shall not
relieve any other Lender of its obligation, if any, hereunder to participate in
the making of such Advance, but no Lender shall be responsible for the failure
of any other Lender to participate in the making of any Advance to be made by
such other Lender on the date of any Advance.

SECTION 14.12   GOVERNING LAW.

This Agreement shall be governed by, and construed in accordance with, the laws
of the State of New York.

SECTION 14.13   EXECUTION IN COUNTERPARTS.

This Agreement may be executed in any number of counterparts and by different
parties hereto in separate counterparts, each of which when so executed shall be
deemed to be an original and all of which taken together shall constitute one
and the same agreement.  Delivery by a Lender, the Arranger or the
Administrative Agent of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement by a Lender, the Arranger or the Administrative
Agent.

SECTION 14.14   CONFIDENTIALITY.

Neither the Administrative Agent, the Arranger nor any Lender shall:

     (a)  disclose any Confidential Information to any Person without the
          consent of the Borrower, other than:

          (i)  to the Administrative Agent's or such Lender's Affiliates and
               their officers, directors, employees, agents, auditors and
               advisors and to actual or prospective assignees and participants,
               and then only on a confidential basis

                                      129
<PAGE>

               and if such prospective assignees and participants undertake to
               comply with this Section 14.14 as if it were a Lender;

         (ii)  as required by any law, rule or regulation or judicial process;

        (iii)  as requested or required by any state, federal or foreign
               authority or examiner regulating banks or banking (whether or not
               having force of law);

         (iv)  to EKN, Ericsson or Ericsson Radio Systems; or

          (v)  to the extent reasonably required in connection with the exercise
               of any power or remedy under a Loan Document (except, prior to a
               notice of acceleration being served on the Borrower pursuant to
               Section 12.1, in connection with a sale of any Loan Document to a
               competitor of the Grandparent or any of its Subsidiaries);

     (b)  and the Borrower shall not, and shall cause its Subsidiaries and
          Affiliates not to, disclose the terms of this Agreement, the other
          Loan Documents or the transactions contemplated hereby to any Person
          without the consent of the other parties hereto, except:

          (i)  to any other lender that is a party to a Permitted Loan Agreement
               (as defined in the Intercreditor Agreement) and that shall have
               agreed to be bound by the provisions of this paragraph;

         (ii)  to the extent that such terms or transactions become generally
               available to the public;

        (iii)  to their respective Affiliates and their officers, directors,
               employees, agents, advisors and (in the case of the Lenders) to
               actual or prospective assignees and participants, in each case to
               the extent that the Administrative Agent, any Lender or the
               Borrower deems necessary or appropriate;

         (iv)  as required by any law, rule or regulation or judicial process;
               and

          (v)  as requested by any state, federal or foreign regulatory
               authority.

A reasonable period of time prior to making any disclosure with respect to such
terms and transactions that is permitted under clause (iv) or (v) of the
preceding sentence, the party proposing, or whose Affiliate is proposing, to
make such disclosure will consult with the other party concerning the need for
and scope of any such disclosure.

     (c)  The Administrative Agent, the Arranger and each Lender:

                                      130

          (a) is entitled to give any information required by EKN and to allow
              inspection of the files of the Administrative Agent, the Arranger
              or such Lender which relate to this Agreement and the other Loan
              Documents and to make copies thereof; and

          (b) is entitled to give information to EKN in connection with the
              implementation of this Agreement.

     (d)  EKN and the Collateral Agent may disclose any Confidential Information
          as follows:

          (i)  to any Lender or to the Administrative Agent's or such Lender's
               or EKN's Affiliates and their officers, directors, employees,
               agents, auditors and advisors and to actual or prospective
               assignees and participants, but only on a confidential basis and
               if such prospective assignees and participants undertake to
               comply with this Section 14.14 as if it were a Lender;

         (ii)  as required by any law, rule or regulation or judicial process;

        (iii)  as requested or required by any state, federal or foreign
               authority or examiner regulating export credit agencies, banks or
               banking (whether or not having force of law);

         (iv)  to Ericsson or Ericsson Radio Systems; or

          (v)  to the extent reasonably required in connection with the exercise

               notice of acceleration being served on the Borrower pursuant to
               Section 12.1, in connection with a sale of any Loan Document to a
               competitor of the Grandparent or any of its Subsidiaries).

SECTION 14.15   CONSENT TO JURISDICTION.

The Borrower irrevocably:

     (a)  submits to the jurisdiction of any New York state or federal court
          sitting in New York City and any appellate court from any thereof in
          any action or proceeding arising out of or relating to any Loan
          Document;

     (b)  agrees that all claims in respect of such action or proceeding may be
          heard and determined in such New York state or in such federal court;

     (c)  waives, to the fullest extent that it may effectively do so, the
          defense of an inconvenient forum to the maintenance of such action or
          proceeding;

                                      131
<PAGE>

     (d)  consents to the service of any and all process in any such action or
          proceeding by the mailing of copies of such process to such Borrower
          at its address specified in Section 14.2; and

     (e)  agrees that a final judgment in any such action or proceeding shall be
          conclusive and may be enforced in other jurisdictions by suit on the
          judgment or in any other manner provided by law.

Nothing in this Section 14.15 shall affect the right of the Administrative Agent
or any Lender to serve legal process in any other manner permitted by law or

or proceeding against any Borrower or its property in the courts of other
jurisdictions.

modification and amendment of the Intercreditor Agreement, the Borrower Security
Agreement, the Parent Pledge Agreement, the Mortgages and/or any other Loan
Document at any time, including without limitation the reasonable fees and
expenses of counsel (including reasonable allocated costs and expenses of in-
house counsel and legal staff) and the costs and expenses incurred by the
Collateral Agent in the course of performing its duties and obligations as
Collateral Agent.

SECTION 14.17   AMENDMENTS, ETC., TO INTERCREDITOR AGREEMENT.

Neither the Administrative Agent nor the Lenders shall consent to any amendment
or modification of, supplement to, replacement of or substitution for the
Intercreditor Agreement unless either:

     (a)  the Borrower shall have consented thereto in writing, or

     (b)  at the time at which such amendment, modification or waiver is entered
          into a Potential Event of Default or Event of Default, or any event
          that, with the passage of time or giving of notice or both, would
          constitute an event of default under any other Permitted Loan
          Agreement, shall have occurred and be continuing.

SECTION 14.18   WAIVER OF JURY TRIAL.

Each of the Borrower, the Administrative Agent and the Lenders irrevocably
waives all right to trial by jury in any action, proceeding or counterclaim
(whether based on contract, tort or otherwise) arising out of or relating to any
of the Loan Documents, the Advances or the actions of the

                                      132
