                                   The Credits

               SECTION 2.01. Commitments. (a) Subject to the terms and
conditions set forth herein, each Facility A Lender agrees to make Loans in US
Dollars from time to time during the Availability Period to MTS in an aggregate
principal amount that will not result in (i) such Lender's Facility A Exposure

<PAGE>   35

exceeding such Lender's Facility A Commitment or (ii) the sum of the total
Facility A Exposures exceeding the total Facility A Commitments.

               (b) Subject to the terms and conditions set forth herein, each
Facility B Lender agrees to make Loans from time to time during the Availability
Period to TRKK in Yen, in an aggregate principal amount that will not result in
such Lender's Facility B Exposure exceeding such Lender's Facility B Commitment
or the sum of the total Facility B Exposures exceeding the total Facility B
Commitments.

               (c) Within the foregoing limits and subject to the terms and
conditions set forth herein, the Borrowers may borrow, prepay and reborrow
Loans.

               (d) In the event that any Facility B Lenders have not made Loans
under the Existing Credit Agreement to repay Facility B Swingline Loans (as
defined under the Existing Credit Agreement) outstanding on the Effective Date,
such Facility B Lenders will make Loans under Facility B in an amount equal to
such outstanding Facility B Swingline Loans, the proceeds of which shall be
applied to repay the Facility B Swingline Loans. The application of such
proceeds shall be deemed to satisfy the obligations of such Facility B Lenders
under Sections 2.05B(c) and 9.03(c) of the Existing Credit Agreement, which
obligations shall continue in effect until such time as the Facility B Swingline
Loans have been paid in full.

               SECTION 2.02. Loans and Borrowings. (a) Each Loan shall be made
as part of a Borrowing consisting of Loans made by the Lenders ratably in
accordance with their respective Facility A or Facility B Commitments, as the
case may be. The failure of any Lender to make any Loan required to be made by
it shall not relieve any other Lender of its obligations hereunder; provided
that the Commitments of the Lenders are several and no Lender shall be
responsible for any other Lender's failure to make Loans as required.

               (b) Subject to Section 2.12, (i) each Borrowing denominated in US
Dollars shall be comprised entirely of ABR Loans or Eurocurrency Loans as MTS
may request in accordance herewith, and (ii) each Borrowing denominated in Yen
shall be comprised entirely of Yen Base Rate Loans or Eurocurrency Loans as TRKK
may request in accordance herewith. Each Lender at its option may make any
Eurocurrency Loan by causing any domestic or foreign branch or a Lending
Affiliate to make such Loan; provided that (x) any exercise of such option shall
not affect the obligation of the Applicable Borrower to repay such Loan in
accordance with the terms of this Agreement and (y) any such branch or Lending
Affiliate of a Facility B Lender shall be a resident of (or have its applicable
lending office in), and will

<PAGE>   36

Borrowings from such branch or Lending Affiliate if payments thereunder are made
by TRKK from a location in Japan.

               (c) At the commencement of each Interest Period for any
Eurocurrency Borrowing, such Borrowing shall be in an aggregate amount that is
an integral multiple of US$100,000 and not less than US$5,000,000 (for such
Borrowing denominated in US Dollars) or an integral multiple of Yen10,000,000
and not less than Yen500,000,000 (for such Borrowing denominated in Yen). At the
time that each ABR Borrowing or Yen Base Rate Borrowing is made, such Borrowing
shall be in an aggregate amount that is an integral multiple of US$100,000 and
not less than US$1,000,000 (for such Borrowing denominated in US Dollars) or an
integral multiple of Yen10,000,000 and not less than Yen100,000,000 (for such
Borrowing denominated in Yen); provided that an ABR Borrowing may be in an
aggregate amount that is equal to the entire unused balance of the Facility A
Commitments if such balance is less then US$1,000,000 and a Yen Base Rate
Borrowing may be in an aggregate amount that is equal to the entire unused
balance of the Facility B Commitments if such balance is less then
Yen100,000,000. Borrowings of more than one Type may be outstanding at the same
time; provided that there shall not at any time be more than a total of five
Eurocurrency Borrowings outstanding under each of Facility A and Facility B.

               (d) Notwithstanding any other provision of this Agreement, a
Borrower shall not be entitled to request, or to elect to convert or continue,
any Borrowing if the Interest Period requested with respect thereto would end
after the Maturity Date.

               SECTION 2.03. Requests for Borrowings. To request a Borrowing,
the Applicable Borrower shall notify the Applicable Agent of such request by
telephone (a) in the case of a Facility A Eurocurrency Borrowing, not later than
1:30 p.m., Local Time, three Business Days before the date of the proposed
Borrowing, (b) in the case of a Facility B Eurocurrency Borrowing, not later
than 11:00 a.m., Local Time, three Business Days before the date of the proposed
Borrowing, (c) in the case of an ABR Borrowing, not later than 1:30 p.m., Local
Time, one Business Day before the date of the proposed Borrowing and (d) in the
case of a Yen Base Rate Borrowing, not later than 11:00 a.m., Local Time, two
Business Days before the date of the proposed Borrowing; provided that the
initial Borrowing under Facility B may be requested at such time, not later than
one Business Day prior to such Borrowing, as the Applicable Borrower and the
Applicable Agent may agree upon (and such request, if the Applicable Agent shall
so agree, may be submitted prior to the Effective Date). Each such telephonic
Borrowing Request shall be irrevocable and shall

<PAGE>   37

be confirmed promptly by hand delivery or telecopy to the Applicable Agent of a
written Borrowing Request in a form approved by the Applicable Agent and signed
by the Applicable Borrower. Each such telephonic and written Borrowing Request
shall specify the following information in compliance with Section 2.02:

               (i) the aggregate amount of the requested Borrowing;

               (ii) the date of such Borrowing, which shall be a Business Day;

               (iii) if such Borrowing is a Facility A Borrowing, whether such
        Borrowing is to be an ABR Borrowing or a Eurocurrency Borrowing, and if
        such Borrowing is a Facility B Borrowing, whether such Borrowing is to
        be a Yen Base Rate Borrowing or a Eurocurrency Borrowing; and

               (iv) the location and number of the Applicable Borrower's account
        to which funds are to be disbursed, which shall comply with the
        requirements of Section 2.04.

If no election as to the Type of a Facility A Borrowing is specified, then the
requested Borrowing shall be an ABR Borrowing. If no election as to the Type of
a Facility B Borrowing is specified, then the requested Borrowing shall be a Yen
Base Rate Borrowing. If no Interest Period is specified with respect to any
Eurocurrency Borrowing requested or deemed to have been requested, then the
Applicable Borrower shall be deemed to have selected an Interest Period of one
month's duration. Promptly following receipt of a Borrowing Request in
accordance with this Section, the Applicable Agent shall advise each Facility A
or Facility B Lender, as the case may be, of the details thereof and of the
amount of such Lender's Loan to be made as part of the requested Borrowing.

               SECTION 2.04. Funding of Borrowings. (a) Each Lender shall make
each Loan to be made by it hereunder on the proposed date thereof by wire
transfer of immediately available funds by (a) in the case of a Facility A
Borrowing, not later than 1:30 p.m., Local Time, and (b) in the case of a
Facility B Borrowing, not later than 12:00 noon, Local Time, to the account of
the Applicable Agent most recently designated by it for such purpose by notice
to the Lenders. The Applicable Agent will make such Loans available to the
Applicable Borrower by promptly crediting the amounts so received, in like
funds, to an account of the Applicable Borrower maintained with the Applicable
Agent and designated by the Applicable Borrower in the applicable Borrowing
Request.

<PAGE>   38

               (b) Unless the Applicable Agent shall have received notice from a
Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Applicable Agent such Lender's share of such Borrowing,
the Applicable Agent may assume that such Lender has made such share available
on such date in accordance with paragraph (a) of this Section and may, in
reliance upon such assumption, make available to the Applicable Borrower a
corresponding amount. In such event, if a Lender has not in fact made its share
of the applicable Borrowing available to the Applicable Agent, then the
applicable Lender and the Applicable Borrower severally agree to pay to the
Applicable Agent forthwith on demand such corresponding amount with interest
thereon (the Applicable Agent hereby agreeing that it will first make such
demand on the applicable Lender), for each day from and including the date such
amount is made available to the Applicable Borrower to but excluding the date of
payment to the Applicable Agent, at (i) in the case of such Lender, the greater
of the Federal Funds Effective Rate (in the case of Borrowings denominated in US
Dollars) and a rate determined by the Applicable Agent in accordance with
banking industry rules on interbank compensation or (ii) in the case of the
Applicable Borrower, the interest rate applicable to ABR Loans (in the case of
Borrowings denominated in US Dollars) or the Yen Base Rate plus 2.5% per annum
(in the case of Borrowings denominated in Yen). If such Lender pays such amount
to the Applicable Agent, then such amount shall constitute such Lender's Loan
included in such Borrowing.

               SECTION 2.05. Interest Elections. (a) Each Borrowing initially
shall be of the Type specified in the applicable Borrowing Request. Each
Eurocurrency Borrowing shall have an initial Interest Period as specified in the
applicable Borrowing Request. Thereafter, the Applicable Borrower may elect to
convert any Borrowing to a Borrowing of a different permitted Type or to
continue any Borrowing, all as provided in this Section. The Applicable Borrower
may elect different options with respect to different portions of the affected
Borrowing, in which case each such portion shall be allocated ratably among the
applicable Lenders holding the Loans comprising such Borrowing, and the Loans
comprising each such portion shall be considered a separate Borrowing.

               (b) To make an election pursuant to this Section, the Applicable
Borrower shall notify the Administrative Agent of such election by telephone by
the time that a Borrowing Request would be required under Section 2.03 if the
Applicable Borrower were requesting a Borrowing of the Type resulting from such
election to be made on the effective date of such election. Each such telephonic
Interest Election Request shall be irrevocable and shall be confirmed promptly
by hand delivery or telecopy to the Administrative Agent of a written Interest
Election Request in a

<PAGE>   39

form approved by the Administrative Agent and signed by the Applicable Borrower.

               (c) Each telephonic and written Interest Election Request shall
specify the following information in compliance with Section 2.02:

               (i) the Borrowing to which such Interest Election Request applies
        and, if different options are being elected with respect to different
        portions thereof, the portions thereof to be allocated to each resulting
        Borrowing (in which case the information to be specified pursuant to
        clauses (iii) and (iv) below shall be specified for each resulting
        Borrowing);

               (ii) the effective date of the election made pursuant to such
        Interest Election Request, which shall be a Business Day; and

               (iii) in the case of a Facility A Borrowing, whether the
        resulting Borrowing is to be an ABR Borrowing or a Eurocurrency
        Borrowing, and in the case of a Facility B Borrowing, whether the
        resulting Borrowing is to be a Yen Base Rate Borrowing or a Eurocurrency
        Borrowing.

               (d) Promptly following receipt of an Interest Election Request,
the Applicable Agent shall advise each applicable Lender of the details thereof
and of such Lender's portion of each resulting Borrowing.

               (e) If the Applicable Borrower fails to either to deliver a
timely Interest Election Request with respect to a Eurocurrency Borrowing or to
notify the Applicable Agent that it will repay such Borrowing at the end of the
interest Period applicable thereto, in either case prior to the third Business
Day before the end of such Interest Period, then at the end of such Interest
Period such Borrowing shall be continued as a Eurocurrency Borrowing with an
Interest Period of one month. Notwithstanding any contrary provision hereof, if
an Event of Default has occurred and is continuing and the Administrative Agent,
at the request of the Required Lenders, so notifies the Applicable Borrower or
Borrowers, then, so long as an Event of Default is continuing (i) no outstanding
Borrowing may be converted to or continued as a Eurocurrency Borrowing and (ii)
unless repaid, each Eurocurrency Borrowing denominated in US Dollars shall be
converted to an ABR Borrowing at the end of the Interest Period applicable
thereto and each Eurocurrency Borrowing denominated in Yen shall be converted to
a Yen Base Rate Borrowing at the end of the Interest Period applicable thereto.

               SECTION 2.06. Optional Termination and Reduction of Commitments.
(a) The Borrowers may at any time terminate, or from time to time reduce, the
Facility A and Facility B Commitments, pro rata as between Facility A and
Facility B; provided that (i) each reduction of the Commitments shall be in an
amount that is an integral multiple of US$100,000 (including the US Dollar
Equivalent of the relevant Yen denominated amount with respect to Facility B)
and not less than US$5,000,000 (including the US Dollar Equivalent of the
relevant Yen denominated amount with respect to Facility B) and (ii) the
Borrowers shall not terminate or reduce the Commitments if, after giving effect
to any concurrent prepayment of the Loans in accordance with Section 2.08 and
2.09, (x) the sum of the Facility A Exposures would exceed the total Facility A
Commitments or (y) the sum of the Facility B Exposures would exceed the total
Facility B Commitments.

               (b) The Borrowers shall notify the Administrative Agent of any
election to terminate or reduce the Facility A and Facility B Commitments under
paragraph (a) of this Section at least three Business Days prior to the
effective date of such termination or reduction, specifying such election and
the effective date thereof. Promptly following receipt of any notice, the
Administrative Agent shall advise the Lenders of the contents thereof. Each
notice delivered by the Borrowers pursuant to this Section shall be irrevocable;
provided that a notice of termination of the Commitments delivered by the
Borrowers may state that such notice is conditioned upon the effectiveness of
other credit facilities, in which case such notice may be revoked by the
Borrowers (by notice to the Administrative Agent on or prior to the specified
effective date) if such condition is not satisfied. Any termination or reduction
of the Commitments shall be permanent. Each reduction of the Facility A or
Facility B Commitments shall be made ratably among the Facility A and Facility B
Lenders respectively in accordance with their respective Commitments.

               SECTION 2.07. Repayment of Loans; Evidence of Debt. (a) Each
Borrower hereby unconditionally promises to pay to the Applicable Agent for the
account of each applicable Lender the then unpaid principal amount of each Loan
on the Maturity Date.

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

               (c) The Applicable Agents shall maintain accounts in which they
shall record (i) in the case of the Administrative Agent, the amount of each
Loan made to MTS, and in the case of

<PAGE>   41

the Japanese Agent, the amount of each Loan made to TRKK, (ii) the Type of each
such Loan and the Interest Period applicable thereto, (iii) the amount and
currency of any principal or interest due and payable or to become due and
payable from the Applicable Borrower to each Lender hereunder and (iv) the
amount of any sum received by such Agent hereunder for the account of the
Lenders and each Lender's share thereof.

               (d) The entries made in the accounts maintained pursuant to
paragraph (b) or (c) of this Section shall be prima facie evidence of the
existence and amounts of the obligations recorded therein; provided that the
failure of any Lender or the Applicable Agents to maintain such accounts or any
error therein shall not in any manner affect the obligation of the Borrowers to
repay the Loans in accordance with the terms of this Agreement.

               (e) Any Lender may request that all Loans made by it to any
Borrower be evidenced by a single promissory note. In such event, the Applicable
Borrower shall promptly prepare, execute and deliver to such Lender a promissory
note payable to the order of such Lender (or, if requested by such Lender, to
such Lender and its registered assigns) and in a form approved by the
Administrative Agent. Thereafter, the Loans evidenced by such promissory note
and interest thereon shall at all times (including after assignment pursuant to
Section 9.04) be represented by one or more promissory notes in such form
payable to the order of the payee named therein (or, if such promissory note is
a registered note, to such payee and its registered assigns).

               SECTION 2.08. Optional Prepayment of Loans. (a) The Applicable
Borrower shall have the right at any time and from time to time to prepay any
Borrowing in whole or in part, subject to prior notice in accordance with
paragraph (b) of this Section.

               (b) The Applicable Borrower shall notify the Applicable Agent by
telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of
prepayment of a Eurocurrency Borrowing, not later than (a) in the case of a
Facility A Eurocurrency Borrowing, not later than 1:30 p.m., Local Time, three
Business Days before the date of prepayment, (b) in the case of a Facility B
Eurocurrency Borrowing, not later than 11:00 a.m., Local Time, three Business
Days before the date of prepayment, (c) in the case of an ABR Borrowing, not
later than 1:30 p.m., Local Time, one Business Day before the date of
prepayment, and (d) in the case of a Yen Base Rate Borrowing, not later than
11:00 a.m., Local Time, two Business Days before the date of prepayment. Each
such notice shall be irrevocable and shall specify the prepayment date and the
principal amount of each Borrowing or portion thereof to be prepaid; provided
that, if a notice of prepayment is given in connection with a conditional notice
of termination of the Commitments as

<PAGE>   42

contemplated by Section 2.06, then such notice of prepayment may be revoked if
such notice of termination is revoked in accordance with Section 2.06. Promptly
following receipt of any such notice relating to a Borrowing, the Applicable
Agent shall advise the Lenders of the contents thereof. Each partial prepayment
of any Borrowing shall be in an amount that would be permitted in the case of an
advance of a Borrowing of the same Type as provided in Section 2.02. Each
prepayment of a Borrowing shall be applied ratably to the Loans included in the
prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the
extent required by Section 2.11.

               SECTION 2.09. Mandatory Commitment Reductions and Prepayments.
(a) Unless previously terminated, the Commitments shall terminate on the
Maturity Date.

               (b) The Commitments will be automatically reduced, pro rata as
between Facility A and Facility B (based on the respective aggregate amounts of
the Facility A Commitments and the Facility B Commitments and on Exchange Rates
prevailing on the dates of such Commitment reductions), (i) on July 31, 2001, by
US$15,000,000, and (ii) on October 1, 2001, by an additional US$15,000,000, in
each case in addition to any reductions made pursuant to paragraph (d) below
(other than any such reductions resulting from the receipt of net cash proceeds
from the monetization of the cash surrender value of life insurance maintained
by the Parent, MTS or any Subsidiary, which shall be credited against the
reductions required to be made under this paragraph), and the Facility A
Borrowings and Facility B Borrowings will be prepaid to the extent required
under paragraph (c) below after giving effect to such reductions. On or before
December 31, 2001, the aggregate Commitments shall be reduced to an amount not
greater than US$100,000,000.

               (c) If on any date the total Facility A Exposures shall be
greater than the total Facility A Commitments, the Administrative Agent shall so
notify MTS and MTS shall prepay Loans on such date in such amounts as shall be
necessary to eliminate such excess. If on any date the total Facility B
Exposures shall be greater than the total Facility B Commitments, the
Administrative Agent shall so notify the Borrowers' Agent and TRKK shall prepay
Loans on such date in such amounts as shall be necessary to eliminate such
excess.

               (d) In the event and on each occasion that any Net Cash Proceeds
are received by or on behalf of the Parent, MTS or any Subsidiary in respect of
any Prepayment Event, the Commitments shall automatically be reduced, pro rata
as between Facility A and Facility B (based on the respective aggregate amounts
of the Facility A Commitments and the Facility B Commitments and on Exchange
Rates prevailing on the dates of such Commitment reductions), by an amount equal
to such Net Cash

<PAGE>   43
Proceeds and the Loans will be prepaid in an amount equal to such Net Cash
Proceeds, pro rata as between Facility A and Facility B based on the respective
aggregate amounts of the Loans outstanding under Facility A and Facility B.
Notwithstanding the foregoing provisions of this paragraph, if the
Administrative Agent, with the consent of each Lender, shall so notify the
Borrowers' Agent, the Net Cash Proceeds of any Prepayment Event will be applied
as between Facility A and Facility B in such other manner as the Lenders shall
direct with a view to minimizing withholding taxes referred to in clause (iv) of
the definition of "Net Cash Proceeds".

               (e) All prepayments under this Section 2.09 shall be subject to
Section 2.14, but shall otherwise be without premium or penalty.

               SECTION 2.10. Fees. (a) MTS agrees to pay and/or cause TRKK to
pay for the account of each applicable Lender a commitment fee of 0.50% per
annum on the amount of such Lender's unused Commitments under the Credit
Facilities. Commitment fees shall be computed on the basis of a year of 360 days
and shall accrue on the daily amount of the unused Commitment under the Credit
Facilities of such Lender during the period from and including the date hereof
to but excluding the date on which such Commitment terminates. Accrued
commitment fees shall be payable in arrears on the last day of each month of
each year and on the date on which the Commitments terminate in US Dollars with
respect to Facility A Commitments and in Yen with respect to Facility B
Commitments. Payments of commitment fees by MTS will be made to the
Administrative Agent and payments of commitment fees by TRKK will be made to the
Japanese Agent.

               (b) MTS agrees to pay, and/or cause TRKK to pay, for the account
of each Lender an extension fee of 0.75% on the amount of such Lender's
aggregate Commitments under the Facilities on the Effective Date. Payments of
extension fees in respect of the Facilities will be made in US Dollars to the
Administrative Agent.

               (c) MTS agrees to pay to the Administrative Agent, for its own
account, fees in the amounts and at the times separately agreed upon between MTS
and the Administrative Agent.

               (d) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Applicable Agent for distribution (in the
case of extension fees, commitment fees and participation fees) to the
applicable Lenders. Fees paid shall not be refundable under any circumstances.

               SECTION 2.11. Interest. (a) The Loans comprising each ABR
Borrowing shall bear interest at the Alternate Base Rate plus 2.50% per annum.

<PAGE>   44

               (b) The Loans comprising each Yen Base Rate Borrowing shall bear
interest at the Yen Base Rate plus 2.50% per annum.

               (c) The Loans comprising each Eurocurrency Borrowing shall bear
interest (i) (x) in the case of a Eurocurrency Loan denominated in US Dollars,
at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing
plus 3.50% per annum and (y) in the case of a Eurocurrency Loan denominated in
Yen, at the TIBO Rate for the Interest Period in effect for such Borrowing plus
3.50% per annum.

               (d) Notwithstanding the foregoing, if any principal of or
interest on any Loan or any fee or other amount payable by a Borrower hereunder
is not paid when due, whether at stated maturity, upon acceleration or
otherwise, such overdue amount shall bear interest, after as well as before
judgment, at a rate per annum equal to (i) in the case of overdue principal of
any Loan, 2% per annum plus the rate otherwise applicable to such Loan as
provided in the preceding paragraphs of this Section, (ii) in the case of any
other amount payable in US Dollars, 2% per annum plus the rate applicable to ABR
Loans as provided in paragraph (a) of this Section or (iii) in the case of any
other amount payable in Yen, 2% per annum plus the rate applicable to Yen Base
Rate Loans as provided in paragraph (b) of this Section.

               (e) Accrued interest on each Loan shall be payable in arrears on
each Interest Payment Date for such Loan and, in the case of Facility A or
Facility B Loans, upon termination of the Facility A or Facility B Commitments,
respectively; provided that (i) interest accrued pursuant to paragraph (d) of
this Section shall be payable on demand, (ii) in the event of any repayment or
prepayment of any Loan (other than a prepayment of an ABR Loan prior to the end
of the Availability Period), accrued interest on the principal amount repaid or
prepaid shall be payable on the date of such repayment or prepayment and (iii)
in the event of any conversion of Eurocurrency Loan prior to the end of the
current Interest Period therefor, accrued interest on such Loan shall be payable
on the effective date of such conversion. All interest that accrues under a Loan
shall be payable in the currency of such Loan.

               (f) All interest hereunder shall be computed on the basis of a
year of 360 days, except that interest computed by reference to the Alternate
Base Rate at times when the Alternate Base Rate is based on the Prime Rate and
interest computed by reference to the Yen Base Rate shall be computed on the
basis of a year of 365 days (or 366 days in a leap year), and in each case shall
be payable for the actual number of days elapsed (including the first day but
excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate,
Yen Base Rate and TIBO

<PAGE>   45

Rate shall be determined by the Applicable Agent, and such determination shall
be conclusive absent manifest error.

               (g) The Administrative Agent will furnish to the Applicable
Borrower an invoice setting forth the amount of interest to become due on each
Interest Payment Date.

               SECTION 2.12. Alternate Rate of Interest. If prior to the
commencement of any Interest Period for a Eurocurrency Borrowing:

               (a) the Administrative Agent determines or is advised by the
        Applicable Agent (which determination shall be conclusive absent
        manifest error) that adequate and reasonable means do not exist for
        ascertaining the Adjusted LIBO Rate or the TIBO Rate, as applicable, for
        such Interest Period; or

               (b) the Administrative Agent is advised by the Lenders holding
        Commitments that represent at least 66-2/3% of the total Facility A or
        Facility B Commitments, as the case may be, that the Adjusted LIBO Rate
        or the TIBO Rate, as applicable, for such Interest Period will not
        adequately and fairly reflect the cost to such Lenders (or Lender) of
        making or maintaining their Loans (or its Loan) included in such
        Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrowers' Agent
and the Lenders by telephone or telecopy as promptly as practicable thereafter
and, until the Administrative Agent notifies the Borrowers and the Lenders that
the circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurocurrency Borrowing shall be ineffective
and (A) any such Facility A Borrowing that is requested to be continued shall be
converted on the last day of the then current Interest Period applicable thereto
to an ABR Borrowing, and (B) any such Facility B Borrowing that is requested to
be continued shall be converted on the last day of the then current Interest
Period applicable thereto to a Yen Base Rate Borrowing, and (ii) if any
Borrowing Request requests a Eurocurrency Borrowing, then (A) in the case of a
Facility A Borrowing, such Borrowing shall be made as an ABR Borrowing and (B)
in the case of a Facility B Borrowing, such Borrowing Request shall be made as a
Yen Base Rate Borrowing.

               SECTION 2.13. Increased Costs. (a) If any Change in Law shall:

               (i) impose, modify or deem applicable any reserve, special
        deposit or similar requirement against assets of, deposits with or for
        the account of, or credit extended by,

<PAGE>   46

        any Lender (except any such reserve requirement reflected in the
        Adjusted LIBO Rate); or

               (ii) impose on any Lender or the London interbank market any
        other condition affecting this Agreement, Eurocurrency Loans made by
        such Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurocurrency Loan (or of maintaining its
obligation to make any such Loan) or to reduce the amount of any sum received or
receivable by such Lender hereunder (whether of principal, interest or
otherwise), then MTS will pay to such Lender, without duplication, such
additional amount or amounts as will compensate such Lender for such additional
costs incurred or reduction suffered.

               (b) If any Lender determines that any Change in Law regarding
capital requirements has or would have the effect of reducing the rate of return
on such Lender's capital or on the capital of such Lender's holding company, if
any, as a consequence of this Agreement or the Loans made by such Lender to a
level below that which such Lender or such Lender's holding company could have
achieved but for such Change in Law (taking into consideration such Lender's
policies and the policies of such Lender's holding company with respect to
capital adequacy), then from time to time MTS will pay to such Lender, without
duplication, such additional amount or amounts as will compensate such Lender or
such Lender's holding company for any such reduction suffered.

               (c) A certificate of a Lender setting forth the amount or amounts
necessary to compensate such Lender or its holding company, as the case may be,
as specified in paragraph (a) or (b) of this Section shall be delivered to the
Applicable Borrower and shall be conclusive absent manifest error. The
Applicable Borrower shall pay such Lender, as the case may be, the amount shown
as due on any such certificate within 10 Business Days after receipt thereof.
Such amount shall be payable in the currency in which the corresponding Loan is
denominated.

               (d) Failure or delay on the part of any Lender to demand
compensation pursuant to this Section shall not constitute a waiver of such
Lender's right to demand such compensation; provided that the Applicable
Borrower shall not be required to compensate a Lender pursuant to this Section
for any increased costs or reductions incurred more than 120 days prior to the
date that such Lender notifies the Applicable Borrower of the Change in Law
giving rise to such increased costs or reductions and of such Lender's intention
to claim compensation therefor; provided further that, if the Change in Law
giving rise to such increased

<PAGE>   47
costs or reductions is retroactive, then the 120-day period referred to above
shall be extended to include the period of retroactive effect thereof.

               (e) Notwithstanding the foregoing provisions of this Section, in
determining the amount of any compensation to which it is entitled under this
Section, a Lender shall exclude the effects of any Change in Law regarding
capital requirements to the extent such Change in Law is applicable to such
Lender as a result of a material deterioration in the creditworthiness of such
Lender after the date of this Agreement.

               SECTION 2.14. Break Funding Payments. In the event of (a) the
payment of any principal of any Eurocurrency Loan other than on the last day of
an Interest Period applicable thereto (including as a result of an Event of
Default), (b) the conversion of any Eurocurrency Loan other than on the last day
of the Interest Period applicable thereto, (c) the failure to borrow, convert,
continue or prepay any Loan on the date specified in any notice delivered
pursuant hereto (regardless of whether such notice may be revoked under Section
2.08(b) and is revoked in accordance therewith), or (d) the assignment of any
Eurocurrency Loan other than on the last day of the Interest Period applicable
thereto as a result of a request by the Applicable Borrower pursuant to Section
2.17, or any deemed assignment of any such Loan pursuant to Section 7.02, then,
in any such event, the Applicable Borrower shall compensate each applicable
Lender for the loss, cost and expense attributable to such event. In the case of
a Eurocurrency Loan, such loss, cost or expense to any Lender shall (except in
the case of a deemed assignment of any such Loan pursuant to Section 7.02) be
deemed to equal an amount determined by such Lender to be the excess, if any, of
(i) the amount of interest which would have accrued on the principal amount of
such Loan had such event not occurred, at the Adjusted LIBO Rate or the TIBO
Rate, as the case may be, that would have been applicable to such Loan, for the
period from the date of such event to the last day of the then current Interest
Period therefor (or, in the case of a failure to borrow, convert or continue,
for the period that would have been the Interest Period for such Loan), over
(ii) the amount of interest which would accrue on such principal amount for such
period at the interest rate which such Lender would bid were it to bid, at the
commencement of such period, for US Dollar or Yen deposits, as the case may be,
of a comparable amount and period from other banks in the Eurocurrency market. A
certificate of any Lender setting forth any amount or amounts that such Lender
is entitled to receive pursuant to this Section shall be delivered to the
Applicable Borrower and shall be conclusive absent manifest error. The
Applicable Borrower shall pay such Lender the amount shown as due on any such
certificate within 10 Business Days after receipt thereof in the currency in
which the corresponding Loan is denominated.

<PAGE>   48

               SECTION 2.15. Taxes. (a) Any and all payments by or on account of
any obligation of each Borrower hereunder shall be made free and clear of and
without deduction for any Indemnified Taxes or Other Taxes; provided that if any
Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from
such payments, then (i) the sum payable shall be increased as necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section) the Applicable Agent or Lender (as
the case may be) receives an amount equal to the sum it would have received had
no such deductions been made, (ii) the Applicable Borrower shall make such
deductions and (iii) the Applicable Borrower shall pay the full amount deducted
to the relevant Governmental Authority in accordance with applicable law. Each
Facility B Lender will make any Loans from a lending office that is able under
laws, regulations and treaties in effect on the date hereof to receive payments
of interest from borrowers in Japan free of Japanese withholding tax.

               (b) In addition, but without duplication, each Borrower shall pay
any Other Taxes to the relevant Governmental Authority in accordance with
applicable law.

               (c) Each Borrower shall indemnify the Applicable Agents and each
Lender, within 10 Business Days after written demand therefor, for the full
amount of any Indemnified Taxes or Other Taxes paid by the Applicable Agent or
such Lender, as the case may be, on or with respect to any payment by or on
account of any obligation of each such Borrower hereunder (including Indemnified
Taxes or Other Taxes imposed or asserted on or attributable to amounts payable
under this Section) and any penalties, interest and reasonable expenses arising
therefrom or with respect thereto, whether or not such Indemnified Taxes or
Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or
liability delivered to any Borrower by a Lender, or by an Applicable Agent on
its own behalf or on behalf of a Lender, shall be conclusive absent manifest
error.

               (d) As soon as practicable after any payment of Indemnified Taxes
or Other Taxes by any Borrower to a Governmental Authority, such Borrower shall
deliver to the Applicable Agent the original or a certified copy of a receipt
issued by such Governmental Authority evidencing such payment, a copy of the
return reporting such payment or other evidence of such payment reasonably
satisfactory to the Applicable Agent.

               (e) Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the
Applicable Borrower is located, or any treaty to which such jurisdiction is a
party, with respect to payments under this Agreement shall deliver to such
Borrower

<PAGE>   49

(with a copy to the Applicable Agent), at the time or times prescribed by
applicable law, such properly completed and executed documentation prescribed by
applicable law or reasonably requested by the Applicable Borrower or the
Applicable Agent as will permit such payments to be made without withholding or
at a reduced rate.

               SECTION 2.16. Payments Generally; Pro Rata Treatment; Sharing of
Set-offs. (a) Each Borrower shall make each payment required to be made by it
hereunder (whether of principal, interest or fees, or of amounts payable under
Section 2.13, 2.14 or 2.15, or otherwise), prior to (i) in the case of a
Facility A Borrowing, 1:30 p.m., Local Time, and (ii) in the case of a Facility
B Borrowing, 12:00 noon, Local Time, on the date when due, in immediately
available funds, without set-off or counterclaim. Any amounts received after
such time on any date may, in the discretion of the Applicable Agent, be deemed
to have been received on the next succeeding Business Day for purposes of
calculating interest thereon. All such payments shall be made to (i) the
Administrative Agent at its offices at 270 Park Avenue, New York, New York or
(ii) the Japanese Agent at its offices at Akasaka Park Building, 9th Floor, 2-20
Akasaka 5-chome, Minato-ku, Tokyo 107, Japan, as the case may be. The Applicable
Agent shall distribute any such payments received by it for the account of any
other Person to the appropriate recipient promptly following receipt thereof. If
any payment hereunder shall be due on a day that is not a Business Day, the date
for payment shall be extended to the next succeeding Business Day, and, in the
case of any payment accruing interest, interest thereon shall be payable for the
period of such extension. All payments hereunder for which no currency has been
specified shall be made in US Dollars.

               (b) If at any time insufficient funds are received by and
available to the Applicable Agent to pay fully all amounts of principal,
interest and fees then due hereunder, such funds shall be applied (i) first,
towards payment of interest and fees then due hereunder, ratably among the
parties entitled thereto in accordance with the amounts of interest and fees
then due to such parties, and (ii) second, towards payment of principal then due
hereunder, ratably among the parties entitled thereto in accordance with the
amounts of principal then due to such parties.

               (c) If any Facility A or Facility B Lender shall, by exercising
any right of set-off or counterclaim or otherwise, obtain payment in respect of
any principal of or interest on any of its applicable Loans resulting in such
Lender receiving payment of a greater proportion of the aggregate amount of its
applicable Loans and accrued interest thereon than the proportion received by
any other Facility A or Facility B Lender, then the Lender receiving such
greater proportion shall purchase (for cash

<PAGE>   50

at face value) participations in the Facility A or Facility B Loans of other
Lenders to the extent necessary so that the benefit of all such payments shall
be shared by the applicable Lenders ratably in accordance with the aggregate
amount of principal of and accrued interest on their respective applicable
Loans; provided that (i) if any such participations are purchased and all or any
portion of the payment giving rise thereto is recovered, such participations
shall be rescinded and the purchase price restored to the extent of such
recovery, without interest, and (ii) the provisions of this paragraph shall not
be construed to apply to any payment made by the Applicable Borrower pursuant to
and in accordance with the express terms of this Agreement or any payment
obtained by a Lender as consideration for the assignment of or sale of a
participation in any of its Loans to any assignee or participant, other than to
a Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of
this paragraph shall apply). Each Borrower consents to the foregoing and agrees,
to the extent it may effectively do so under applicable law, that any Lender
acquiring a participation pursuant to the foregoing arrangements may exercise
against any Borrower rights of set-off and counterclaim with respect to such
participation as fully as if such Lender were a direct creditor of such Borrower
in the amount of such participation.

               (d) Unless the Applicable Agent shall have received notice from
the Applicable Borrower prior to the date on which any payment is due to the
Applicable Agent for the account of the Lenders hereunder that the Applicable
Borrower will not make such payment, the Applicable Agent may assume that the
Applicable Borrower has made such payment on such date in accordance herewith
and may, in reliance upon such assumption, distribute to the applicable Lenders
the amount due. In such event, if the Applicable Borrower has not in fact made
such payment, then each of the applicable Lenders severally agrees to repay to
the Applicable Agent forthwith on demand the amount so distributed to such
Lender with interest thereon, for each day from and including the date such
amount is distributed to it to but excluding the date of payment to the
Applicable Agent, at the greater of (i) the Federal Funds Effective Rate (in the
case of payments to be made in US Dollars) and (ii) a rate determined by the
Applicable Agent to reflect such Applicable Agent's cost of funds for overnight
borrowings in Yen (in the case of payments to be made in Yen) and a rate
determined by the Applicable Agent in accordance with banking industry rules on
interbank compensation.

               (e) If any Lender shall fail to make any payment required to be
made by it pursuant to Section 2.04(b) or 2.16(d), then the Applicable Agent
may, in its discretion (notwithstanding any contrary provision hereof), apply
any amounts thereafter received by the Applicable Agent for the account of such
Lender to satisfy such Lender's obligations under such Sections until all such
unsatisfied obligations are fully paid.

<PAGE>   51

               SECTION 2.17. Mitigation Obligations; Replacement of Lenders. (a)
If any Lender requests compensation under Section 2.13, or if any Borrower is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.15, then such
Lender shall use reasonable efforts to designate a different lending office for
funding or booking its Loans hereunder or to assign its rights and obligations
hereunder to another of its offices, branches or affiliates, if, in the judgment
of such Lender, such designation or assignment (i) would eliminate or reduce
amounts payable pursuant to Section 2.13 or 2.15, as the case may be, in the
future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender. The
Borrowers' Agent hereby agrees to pay all reasonable costs and expenses incurred
by any Lender in connection with any such designation or assignment.

               (b) If any Lender requests compensation under Section 2.13, or if
the Applicable Borrower is required to pay any additional amount to any Lender
or any Governmental Authority for the account of any Lender pursuant to Section
2.15, or if any Lender defaults in its obligation to fund Loans hereunder, then
MTS may, at no expense to any such Lender (other than a Lender that has
defaulted in its obligation to fund Loans), upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in
Section 9.04), all its interests, rights and obligations under this Agreement to
an assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) MTS shall have
received the prior written consent of the Administrative Agent, which consent
shall not unreasonably be withheld, (ii) such Lender shall have received payment
of an amount equal to the outstanding principal of its Loans, accrued interest
thereon, accrued fees and all other amounts payable to it hereunder, from the
assignee (to the extent of such outstanding principal and accrued interest and
fees) or the Applicable Borrower (in the case of all other amounts) and (iii) in
the case of any such assignment resulting from a claim for compensation under
Section 2.13 or payments required to be made pursuant to Section 2.15, such
assignment will result in a reduction in such compensation or payments. A Lender
shall not be required to make any such assignment and delegation if, prior
thereto, as a result of a waiver by such Lender or otherwise, the circumstances
entitling MTS to require such assignment and delegation cease to apply.

                                   ARTICLE III

                         Representations and Warranties

               Each Borrower represents and warrants to the Lenders that:

               SECTION 3.01. Organization; Powers. Each of the Parent, the
Borrowers and the Subsidiaries is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, has all
requisite power and authority to carry on its business as now conducted and,
except where the failure to do so, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect, is qualified to
do business in, and is in good standing in, every jurisdiction where such
qualification is required.

               SECTION 3.02. Authorization; Enforceability. The Transactions to
be entered into by each Loan Party are within such Loan Party's corporate or
other powers and have been and will be duly authorized by all necessary
corporate or other action and, if required, stockholder action. This Agreement
has been duly executed and delivered by each Borrower and constitutes, and each
other Loan Document to which any Loan Party is to be a party, when executed and
delivered by such Loan Party, will constitute, a legal, valid and binding
obligation of each Borrower or such Loan Party (as the case may be), enforceable
in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting creditors' rights generally
and subject to general principles of equity, regardless of whether considered in
a proceeding in equity or at law.

               SECTION 3.03. Governmental Approvals; No Conflicts. The
Transactions (a) do not require any consent or approval of, registration or
filing with, or other action by, any Governmental Authority, except such as have
been obtained or made and are in full force and effect and except filings
necessary to perfect Liens created under the Loan Documents, (b) will not
violate any applicable law or regulation or the charter, by-laws or other
organizational documents of the Borrowers or any of the Subsidiaries or any
order of any Governmental Authority, (c) will not violate or result in a default
under any indenture or material agreement or other instrument binding upon the
Borrowers or any of the Subsidiaries or their assets, or give rise to a right
thereunder to require any payment to be made by the Borrowers or any of the
Subsidiaries, and (d) will not result in the creation or imposition of any Lien
on any asset of the Borrowers or any of the Subsidiaries (other than those
created under the Loan Documents).

<PAGE>   53

               SECTION 3.04. Financial Condition; No Material Adverse Change.
(a) (i) The audited consolidated balance sheet of MTS and the Subsidiaries as at
July 31, 2000, and the related consolidated statements of income, shareholders,
equity and cash flows for the fiscal year then ended, (ii) the unaudited
consolidated balance sheet of MTS and the Subsidiaries as at January 31, 2001,
and the related consolidated statements of income, shareholders, equity and cash
flows for the portion of the fiscal year then ended, and (iii) monthly
consolidated balance sheets and statements of income and cash flows of MTS and
the Subsidiaries for each month commencing with November 2000 and ending with
February 2001, all as heretofore delivered to the Lenders, are complete and
correct and fairly present the financial condition of MTS and the Subsidiaries
as at such dates and the results of operations of MTS and the Subsidiaries for
the periods covered by such statements, in each case on a consolidated basis in
accordance with GAAP consistently applied, subject, in the case of the financial
statements delivered pursuant to clauses (ii) and (iii) above, to normal
year-end adjustments and the absence of footnotes.

               (b) Since July 31, 2000, there has been no material adverse
change, and no event that could reasonably be expected to result in a material
adverse change, in the business, assets, operations or condition, financial or
otherwise, of MTS and the Subsidiaries, taken as a whole.

               SECTION 3.05. Properties. (a) Each of MTS and the Subsidiaries
has good title to, or valid leasehold interests in, all its real and personal
property material to its business, except for minor defects in title that do not
interfere in any material respect with its ability to conduct its business as
currently conducted or to utilize such properties for their intended purposes.

               (b) Each of MTS and the Subsidiaries (i) owns all "Tower", "Tower
Records", "Tower Books", "Tower Video" and related trademarks and tradenames,
including those listed on Schedule 11A to the Perfection Certificate, and (ii)
owns, or is licensed or otherwise has rights to use, all other trademarks and
tradenames, copyrights, patents and other intellectual property, in each case
material to its business, and the use thereof by MTS and the Subsidiaries does
not infringe upon the rights of any other Person, except for any such
infringements that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect.

               SECTION 3.06. Litigation and Environmental Matters. (a) There are
no actions, suits or proceedings by or before any arbitrator or Governmental
Authority pending against or, to the knowledge of the Borrowers, threatened
against or affecting MTS or any of the Subsidiaries (i) as to which there is a
reasonable

<PAGE>   54

possibility of an adverse determination and that, if adversely determined, could
reasonably be expected, individually or in the aggregate, to result in a
Material Adverse Effect (other than the Disclosed Matters) or (ii) that involve
this Agreement or the Transactions.

               (b) Except for the Disclosed Matters and except with respect to
any other matters that, individually or in the aggregate, could not reasonably
be expected to result in a Material Adverse Effect, neither MTS nor any of the
Subsidiaries (i) to the best of its knowledge, has failed to comply with any
Environmental Law or to obtain, maintain or comply with any permit, license or
other approval required under any Environmental Law, (ii) to the best of its
knowledge, has become subject to any Environmental Liability, (iii) has received
notice of any claim with respect to any Environmental Liability or (iv) knows of
any basis for any Environmental Liability.

               (c) Since the date of April 23, 1998, there has been no change in
the status of the Disclosed Matters that, individually or in the aggregate, has
resulted in, or materially increased the likelihood of, a Material Adverse
Effect.

               SECTION 3.07. Compliance with Laws and Agreements; Margin
Regulations. (a) Each of MTS and the Subsidiaries is in compliance with all
laws, regulations and orders of any Governmental Authority applicable to it or
its property and all indentures, agreements and other instruments binding upon
it or its property, except where the failure to do so, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse
Effect. No Default has occurred and is continuing.

               (b) The Borrowers have not, and are not presently, engaged in the
business of extending credit for the purpose of purchasing or carrying "margin
stock" (within the meaning of Regulations U of the Board). No part of the
proceeds of the Loans will be used to purchase or carry any margin stock or to
extend credit to others for the purpose of purchasing or carrying any margin
stock.

               SECTION 3.08. Investment and Holding Company Status. Neither MTS
nor any of the Subsidiaries is (a) an "investment company" as defined in, or
subject to regulation under, the Investment Company Act of 1940 or (b) a

upon assumptions believed to be reasonable at the time, after due inquiry.

               SECTION 3.12. Security Documents. (a) The Pledge Agreements are

and other intellectual property are owned by the Persons indicated in the
Perfection Certificate.

               (d) The Mortgages will, when executed and delivered, be effective
to create in favor of the Collateral Agent, legal, valid and enforceable Liens
on all right, title and interest of the grantors thereunder in and to the
Mortgaged Properties and the proceeds thereof, and when the Mortgages are filed
in the appropriate offices in the jurisdictions in which the mortgaged
Properties are located, the Mortgages will constitute perfected first priority
Liens on and security interests in all right, title and interest of such
grantors in and to the Mortgaged Properties and the proceeds thereof, subject
only to Liens existing on the date hereof and expressly permitted by Section
6.02 (subject, in the case of the Designated Mortgaged Properties, to the

otherwise transfer any property or assets to, or purchase, lease or otherwise
acquire any property, assets or services from, or otherwise engage in any other
transactions with, any of their respective Affiliates, except (a) transactions
in the ordinary course of business that are at prices and on terms and
conditions not less favorable to the relevant Borrower or such Subsidiary than
could be obtained on an arm's-length basis from unrelated third parties, (b)
transactions between or among the Borrowers and the Subsidiaries not involving
any other Affiliate and (c) any Restricted Payment permitted by Section 6.08.

               SECTION 6.10. Restrictive Agreements. The Borrowers will not, nor

any of its property or assets, or (b) the ability of any Subsidiary to pay
dividends or other distributions with respect to any shares of its capital stock

to Guarantee Indebtedness of a Borrower or any other Subsidiary; provided that
(i) the foregoing shall not apply to restrictions and conditions imposed by law
or by any Loan Document or Subordinated Debt Document, (ii) the foregoing shall
not apply to restrictions and conditions existing on April 23, 1998, identified
on Schedule 6.10 (but shall apply to any extension or renewal of, or any
amendment or modification expanding the scope of, any such restriction or
condition), (iii) the foregoing shall not apply to customary restrictions and
conditions contained in agreements relating to the sale of a Subsidiary pending

apply to customary provisions in leases and other contracts restricting the
assignment thereof.

not, nor will they permit the Parent or any Subsidiary to, (a) amend, modify or
waive any of its rights under any Senior Subordinated Debt Document if the
effect of such amendment, modification or waiver would be to change the terms on
which any Senior Subordinated Debt is subordinated to any other obligations,
shorten the maturity or weighted average life to maturity of any Senior
Subordinated Debt, require, either on one or more fixed dates or upon the
happening of one or more events, the repayment, purchase or defeasance of any
Senior Subordinated Debt, add any covenant or make more restrictive the
covenants benefitting any Senior Subordinated Debt or otherwise modify the terms
of any Senior Subordinated Debt in a manner that is adverse to the Borrowers or

               (g) any event or condition occurs that results in any Material
        Indebtedness (or obligations under leases of real property that would
        constitute Material Indebtedness but for the proviso in the definition
        of "Capital Lease Obligations") becoming due prior to the scheduled

        provided that this paragraph (g) shall not apply to secured Indebtedness
        that becomes due as a result of the voluntary sale or transfer of the

               (h) an involuntary proceeding shall be commenced or an
        involuntary petition shall be filed seeking (i) liquidation,
        reorganization or other relief in respect of the Parent, any Borrower or
        any Material Subsidiary or its debts, or of a substantial part of its
        assets, under any Federal, state or foreign bankruptcy, insolvency,
        receivership or similar law now or hereafter in effect or

<PAGE>   79

        (ii) the appointment of a receiver, trustee, custodian, sequestrator,
        conservator or similar official for the Parent, any Borrower or any
        Material Subsidiary or for a substantial part of its assets, and, in any
        such case, such proceeding or petition shall continue undismissed for 60
        days or an order or decree approving or ordering any of the foregoing
        shall be entered;

               (i) the Parent, any Borrower or any Material Subsidiary shall (i)
        voluntarily commence any proceeding or file any petition seeking
        liquidation, reorganization or other relief under any Federal, state or

        rendered against the Parent, any Borrower, any Subsidiary or any
        combination thereof and the same shall remain undischarged for a period
        of 30 consecutive days during which execution shall not be effectively
        stayed, or any action shall be legally taken by a judgment creditor to
        attach or levy upon any assets of the Parent, any Borrower or any
        Subsidiary to enforce any such judgment;

               (l) an ERISA Event shall have occurred that, in the opinion of
        the Required Lenders, when taken together with all other ERISA Events
        that have occurred, could reasonably be expected to result in a Material
        Adverse Effect;

               (m) any Lien purported to be created under the Security Documents
        shall cease to be, or shall be asserted by any Loan Party not to be, a
        valid and perfected first priority Lien on any significant portion of

<PAGE>   80

        except (i) as a result of the sale or other disposition of the
        applicable Collateral in a transaction permitted under the Loan
        Documents or (ii) as a result of the Collateral Agent's failure to
        maintain possession of any stock certificates delivered to it under a
        Pledge Agreement;

               (n) any Guarantee of any Guarantor under the Guarantee Agreement

        legal, valid and binding obligation of such Guarantor; or

               (o) a Change in Control shall occur;

then, and in every such event (other than an event with respect to a Borrower
described in paragraph (h) or (i) of this Section), and at any time thereafter
during the continuance of such event, the Administrative Agent may, and at the
request of the Required Lenders shall, by notice to the Borrower's Agent, take
either or both of the following actions, at the same or different times: (i)
terminate the Commitments, and thereupon the Commitments shall terminate
immediately, and (ii) declare the Loans then outstanding to be due and payable
in whole (or in part, in which case any principal not so declared to be due and
payable may thereafter be declared to be due and payable), and thereupon the
principal of the Loans so declared to be due and payable, together with accrued
interest thereon and all fees and other obligations of the Borrowers accrued
hereunder, shall become due and payable immediately, without presentment,
demand, protest or other notice of any kind, all of which are hereby waived by
the Borrowers; and in case of any event with respect to a Borrower described in
paragraph (h) or (i) of this Section, the Commitments shall automatically
terminate and the principal of the Loans then outstanding, together with accrued
interest thereon and all fees and other obligations of the Borrowers accrued
hereunder, shall automatically become due and payable, without presentment,

the Borrowers.

               SECTION 7.02. Implementation of CAM. On the CAM Exchange Date,
the Lenders shall automatically and without further act be deemed to have
exchanged interests in the Designated Obligations outstanding under the Credit
Facilities such that in lieu of the interest of each Lender in the Designated
Obligations outstanding under each Credit Facility in which it shall participate
as of such date, such Lender shall hold an interest in the Designated
Obligations outstanding under each of the Credit Facilities, whether or not such
Lender shall previously have participated therein, equal to such Lender's CAM
Percentage thereof. Each Participant that has acquired a participation from any
Lender as contemplated by Section 9.04(e) and each Loan Party hereby consents
and agrees to the CAM Exchange. Each Loan Party agrees from time to time to
execute

<PAGE>   81

and deliver to the Administrative Agent all such promissory notes and other
instruments and documents as the Administrative Agent shall reasonably request
to evidence and confirm the respective interests of the Lenders after giving
effect to the CAM Exchange, and each Lender agrees to surrender any promissory
notes originally received by it in connection with its Loans hereunder to the
Administrative Agent against delivery of any promissory notes so executed and
delivered; provided, however, that the failure of any Loan Party to execute or
deliver or of any Lender to accept any such promissory note, instrument or
document shall not affect the validity or effectiveness of the CAM Exchange.

                                  ARTICLE VIII

                                   The Agents

               Each of the Lenders hereby irrevocably appoints each of the
Agents as its agent and authorizes each Agent to take such actions on its behalf
and to exercise such powers as are delegated to such Agent by the terms hereof,
together with such actions and powers as are reasonably incidental thereto.

               Each bank serving as an Agent hereunder shall have the same
rights and powers in its capacity as a Lender as any other Lender and may
exercise the same as though it were not an Agent, and such bank and its
Affiliates may accept deposits from, lend money to and generally engage in any
kind of business with any Borrower or any Subsidiary or other Affiliate thereof
as if it were not an Agent hereunder.

               The Agents shall not have any duties or obligations except those
expressly set forth herein. Without limiting the generality of the foregoing,
(a) no Agent shall be subject to any fiduciary or other implied duties (other
than as expressly assumed in the Security Documents), regardless of whether a
Default has occurred and is continuing, (b) no Agent shall have any duty to take
any discretionary action or exercise any discretionary powers, except
discretionary rights and powers expressly contemplated hereby that such Agent is
required to exercise in writing by the Required Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 9.02), and (c) except as expressly set forth herein, no
Agent shall have any duty to disclose, and shall not be liable for the failure
to disclose, any information relating to any Borrower or any of its Subsidiaries
that is communicated to or obtained by the bank serving as Agent or any of its
Affiliates in any capacity. No Agent shall be liable for any action taken or not
taken by it with the consent or at the request of the Required Lenders (or

<PAGE>   82

such other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 9.02) or in the absence of its own gross
negligence or wilful misconduct. Each Agent shall be deemed not to have
knowledge of any Default unless and until written notice thereof is given to
such Agent by a Borrower or a Lender, and no Agent shall be responsible for or
have any duty to ascertain or inquire into (i) any statement, warranty or
representation made in or in connection with this Agreement or any other Loan
Document, (ii) the contents of any certificate, report or other document
delivered hereunder or under any other Loan Document or in connection herewith
or therewith, (iii) the performance or observance of any of the covenants,
agreements or other terms or conditions set forth herein, (iv) the validity,
enforceability, effectiveness or genuineness of this Agreement or any other
agreement, instrument or document, or (v) the satisfaction of any condition set
forth in Article IV or elsewhere herein, other than to confirm receipt of items
expressly required to be delivered to such Agent.

               Each Agent shall be entitled to rely upon, and shall not incur
any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. Each Agent also may rely
upon any statement made to it orally or by telephone and believed by it to be
made by the proper Person, and shall not incur any liability for relying
thereon. Each Agent may consult with legal counsel (who may be counsel for a
Borrower), independent accountants and other experts selected by it, and shall
not be liable for any action taken or not taken by it in accordance with the
advice of any such counsel, accountants or experts.

               Each Agent may perform any and all its duties and exercise its
rights and powers by or through any one or more sub-agents appointed by any
Agent. Each Agent and any such sub-agent may perform any and all its duties and
exercise its rights and powers through their respective Related Parties. The
exculpatory provisions of the preceding paragraphs shall apply to any such
sub-agent and to the Related Parties of any such Agent and any such sub-agent,
and shall apply to their respective activities in connection with the
syndication of the Credit Facilities provided for herein as well as activities
as Agent.

               Subject to the appointment and acceptance of a successor Agent as
provided in this paragraph, each Agent may resign at any time by notifying the
Lenders and the Borrowers or the Borrowers and the Required Lenders may replace
any Agent. Upon any such resignation, the Required Lenders shall have the right,
in consultation with the Borrowers' Agent (and with the Borrowers' Agent's
consent, unless an Event of Default shall have occurred and be continuing), to
appoint a successor. If no successor shall have been so appointed by the
Required Lenders

<PAGE>   83

and shall have accepted such appointment within 30 days after the retiring Agent
gives notice of its resignation, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent. Upon any such replacement, the Borrowers and
the Required Lenders shall cause the successor Agent to purchase all of the
replaced Agent's Commitments and the related Loans at the time owing to the
replaced Agent. Upon the acceptance of its appointment as Agent hereunder by a
successor, such successor shall succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. The fees
payable by the Borrowers to a successor Agent shall be the same as those payable
to its predecessor unless otherwise agreed between the Borrower and such
successor. After an Agent's resignation or replacement hereunder, the provisions
of this Article and Section 9.03 shall continue in effect for the benefit of
such retiring or replaced Agent, its sub-agents and their respective Related
Parties in respect of any actions taken or omitted to be taken by any of them
while it was acting as Agent.

               Each Lender acknowledges that it has, independently and without
reliance upon any Agent or any other Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon any Agent or any other Lender and
based on such documents and information as it shall from time to time deem
appropriate, continue to make its own decisions in taking or not taking action
under or based upon this Agreement, any related agreement or any document
furnished hereunder or thereunder.

        Manhattan Plaza, 8th Floor, New York, New York 10081, Attention of Ms.
        Janet Belden (Telecopy No. (212) 552-5658), with a copy to The Chase
        Manhattan Bank, 380 Madison Avenue, 9th Floor, New York, New York 10017,
        Attention of Susan E. Atkins, Managing Director (Telecopy No. (212)
        622-4834);

               (c) if to the Japanese Agent, to it at The Chase Manhattan Bank,
        Tokyo, Banking Services Department, Akasaka Park Building, 9th Floor,
        2-20 Akasaka 5-chome, Minato-ku, Tokyo 107, Japan, Attention of Ms.
        Naoko Morimoto (Telecopy No. 011-81-3-5570-7539); and

               (d) if to any other Lender, to it at its address (or telecopy
        number) set forth in its Administrative Questionnaire.

Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto. All notices and
other communications given to any party hereto in accordance with the provisions
of this Agreement shall be deemed to have been given on the date of receipt.

               SECTION 9.02. Waivers; Amendments. (a) No failure or delay by the
Administrative Agent or any Lender in exercising any right or power hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any abandonment or discontinuance of steps to
enforce such a right or power, preclude any other or further exercise thereof or
the exercise of any other right or power. The rights and remedies of the
Administrative Agent and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any provision of this Agreement or consent to any departure by a Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan shall not
be construed as a waiver of any Default, regardless of whether the
Administrative Agent or any Lender may have had notice or knowledge of such
Default at the time.

               (b) Neither this Agreement nor any provision hereof may be
waived, amended or modified except pursuant to an agreement or agreements in
writing entered into by the Borrowers and the Required Lenders or by the
Borrowers and the Administrative Agent with the consent of the Required Lenders;
provided that no such agreement shall (i) increase the Commitment of any Lender
as in effect at any time without the written consent of such Lender, (ii) reduce
the principal amount of any

<PAGE>   85

Loan or reduce the rate of interest thereon, or reduce any fees payable
hereunder, without the written consent of each Lender affected thereby, (iii)
postpone the date of payment of the principal amount of any Loan or any interest
thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse
any such payment, or postpone the scheduled date of expiration of any
Commitment, without the written consent of each Lender affected thereby, (iv)
change Section 2.16(b) or (c) in a manner that would alter the pro rata sharing
of payments required thereby, or change or waive any provision of Section
5.09(b) or (c), 5.11, 5.13 or 7.02, in each case without the written consent of
each Lender, (v) change any of the provisions of this Section or the definition
of "Required Lenders" or any other provision hereof specifying the number or
percentage of Lenders required to waive, amend or modify any rights hereunder or
make any determination or grant any consent hereunder, or (vi) except for
releases of Collateral required to be effected under Section 9.15, release any
Lien created by the Security Documents or any Guarantee created by the Guarantee
Agreement (other than as permitted pursuant to the terms of this Agreement or
any relevant Security Document) without the written consent of each Lender;
provided further that no such agreement shall (x) amend, modify or otherwise
affect the rights or duties of the Administrative Agent or the Japanese Agent
hereunder without the prior written consent of such Agent or (y) adversely
affect one Credit Facility to a greater extent than the other without the prior
written consent of Lenders representing at least 662/3% of the Commitments and
outstanding Loans under the adversely affected Credit Facility. Without limiting
the foregoing, if and to the extent that any transaction by any Borrower or any
Subsidiary under Section 5.13 or elsewhere in this Agreement for which the
consent of the Required Lenders is required would have any of the effects
referred to (1) in any of the clauses (i) through (vi) of the first proviso
above, then the written consent of each affected Lender shall be required for
such transaction, in addition to the consent of the Required Lenders, or (2) in
clause (x) or (y) of the second proviso, then the written consent of Lenders
representing at least 662/3% of the Commitments and outstanding Loans under the
adversely affected Credit Facility shall be required for such transaction, in
addition to the consent of the Required Lenders.

               SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a) MTS shall
pay (i) all reasonable out-of-pocket expenses incurred by the Administrative
Agent (including in its capacity as Collateral Agent) or any of its Affiliates,
including the reasonable fees, charges and disbursements of counsel for the
Administrative Agent, in connection with the preparation or administration of
this Agreement, any amendments, modifications or waivers of the provisions
hereof or any release of the Liens created by the Security Documents as
contemplated by Section 9.15 (whether or not the transactions contemplated
hereby or thereby

<PAGE>   86

shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by
any Agent or any Lender, including the fees, charges and disbursements of any
counsel for any Agent or any Lender, in connection with the enforcement or
protection of its rights in connection with this Agreement, including its rights
under this Section, or in connection with the Loans made hereunder, including
all such out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Loans and (iii) the reasonable charges and
expenses associated with the Administrative Agent's audits of Collateral, all
records related thereto and the premises upon which any of the Collateral is
located pursuant to the terms of this Agreement or the Security Agreements (it
being agreed that so long as no Event of Default has occurred and is continuing,
MTS shall be required to pay such charges and expenses in connection with not
more than one audit of the Collateral during any fiscal year of MTS) and ongoing
monitoring efforts relating to Sections 6.07, 6.12, 6.13 and 6.14.

               (b) The Borrowers shall, on a joint and several basis, indemnify
the Administrative Agent, each other Agent, and each Lender, and each Related
Party of any of the foregoing Persons (each such Person being called an
"Indemnitee") against, and hold each Indemnitee harmless from, any and all
losses, claims, damages, liabilities and related expenses, including the
reasonable fees, charges and disbursements of any counsel for any Indemnitee,
incurred by or asserted against any Indemnitee arising out of, in connection
with, or as a result of (i) the execution or delivery of this Agreement or any
agreement or instrument contemplated hereby, the performance by the parties
hereto of their respective obligations hereunder or the consummation of the
Transactions or any other transactions contemplated hereby, (ii) any Loan or the
use of the proceeds therefrom, (iii) any actual or alleged presence or release
of Hazardous Materials on or from any property owned or operated by MTS or any
Subsidiary, or any Environmental Liability related in any way to MTS or any
Subsidiary, or (iv) any actual or prospective claim, litigation, investigation
or proceeding relating to any of the foregoing, whether based on contract, tort
or any other theory and regardless of whether any Indemnitee is a party thereto;
provided that such indemnity shall not, as to any Indemnitee, be available to
the extent that such losses, claims, damages, liabilities or related expenses
shall have resulted from the gross negligence or wilful misconduct of such
Indemnitee.

               (c) To the extent that either Borrower fails to pay any amount
required to be paid by it to the Administrative Agent or any other Agent under
paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the
Administrative Agent or such Agent, as the case may be, such Lender's Applicable
Percentage (determined as of the time that the applicable unreimbursed expense
or indemnity payment is sought) of such

<PAGE>   87

unpaid amount; provided that the unreimbursed expense or indemnified loss,
claim, damage, liability or related expense, as the case may be, was incurred by
or asserted against the Administrative Agent or such Agent in its capacity as
such.

               (d) To the extent permitted by applicable law, no Borrower shall
assert, and each Borrower hereby waives, any claim against any Indemnitee, on
any theory of liability, for special, indirect, consequential or punitive
damages (as opposed to direct or actual damages) arising out of, in connection
with, or as a result of, this Agreement or any agreement or instrument
contemplated hereby, the Transactions, any Loan or the use of the proceeds
thereof.

               (e) Each Borrower hereby forever releases, discharges and holds
harmless the Administrative Agent, each other Agent, and each Lender, and each
Related Party of any of the foregoing Persons, and the financial and legal
advisors, directors, trustees, partners, members, employees, agents and advisors
of any of the foregoing (any such person, a "Releasee"), from any and all
losses, claims, damages, demands, debts, liabilities, expenses, obligations,
actions, causes of action, suits, sums of money, accounts, reckonings,
covenants, contracts, controversies, agreements, promises and rights whatsoever,
whenever arising, out of actions or omissions occurring prior to the
effectiveness of this Release, whether arising under the Credit Agreement or the
other Loan Documents, the Transactions, any Loan or Commitment or the use of the
proceeds thereof, or any other agreements, instruments, engagements,
conversations or transactions contemplated by or relating to any of the
foregoing, known or unknown, suspected or unsuspected, contingent or fixed,
liquidated or unliquidated, matured or unmatured, in law, equity or otherwise
that the Borrowers ever had, now have, or hereafter can, shall or may have
against any of the Releasees for, upon, or by reason of any matter, cause,
transaction or thing whatsoever occurring at any time prior to the effectiveness
of this release.

               (f) All amounts due under this Section shall be payable not later
than 30 days after written demand therefor.

               SECTION 9.04. Successors and Assigns. (a) The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns permitted hereby, except that no
Borrower may assign or otherwise transfer any of its rights or obligations
hereunder without the prior written consent of each Lender (and any attempted
assignment or transfer by any Borrower without such consent shall be null and
void). Nothing in this Agreement, expressed or implied, shall be construed to
confer upon any Person (other than the parties hereto, their respective
successors and assigns permitted hereby and, to the extent expressly
contemplated hereby, the Related Parties of each of the

<PAGE>   88

Administrative Agent, the other Agents and the Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

               (b) Any Lender may assign to one or more assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment, Facility A Commitment or Facility B Commitment and
the related Loans at the time owing to it); provided, that (i) except in the
case of an assignment to any Federal Reserve Bank or to a Lender or a Lending
Affiliate of a Lender, the Administrative Agent must give its prior written
consent to such assignment (which consent shall not be unreasonably withheld),
(ii) except in the case of an assignment to a Lender or a Lending Affiliate of a
Lender or an assignment of the entire remaining amount of the assigning Lender's
Facility A Commitment or Facility B Commitment, the amount of the Commitment of
the assigning Lender subject to each such assignment (determined as of the date
the Assignment and Acceptance with respect to such assignment is delivered to
the Administrative Agent) shall not be less than US$5,000,000 (or the
approximate equivalent in Yen based on the then current Exchange Rate) unless
the Administrative Agent otherwise consents, (iii) each partial assignment shall
be made as an assignment of a proportionate part of all the assigning Lender's
rights and obligations under this Agreement (or under one of the Credit
Facilities), (iv) the parties to each assignment shall execute and deliver to
the Administrative Agent an Assignment and Acceptance, together with a
processing and recordation fee of US$3,500, and (v) the assignee, if it shall
not be a Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire. Subject to acceptance and recording thereof pursuant to paragraph
(d) of this Section, from and after the effective date specified in each
Assignment and Acceptance the assignee thereunder shall be a party hereto and,
to the extent of the interest assigned by such Assignment and Acceptance, have
the rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such
Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all of the assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall continue to be entitled to the benefits of Sections
2.13, 2.14, 2.15 and 9.03). Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this paragraph shall
be treated for purposes of this Agreement as a sale by such Lender of a
participation in such rights and obligations in accordance with paragraph (e) of
this Section.

               (c) The Administrative Agent, acting for this purpose as an agent
of the Borrower, shall maintain at one of its offices in The City of New York a
copy of each Assignment and Acceptance

<PAGE>   89

delivered to it and a register for the recordation of the names and addresses of
the Lenders, and the Commitment of, and principal amount of the Loans owing to,
each Lender pursuant to the terms hereof from time to time (the "Register"). The
entries in the Register shall be conclusive absent manifest error, and the
Borrowers, the Administrative Agent and the Lenders may treat each Person whose
name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary. The Register shall be available for inspection by the Borrowers and
any Lender, at any reasonable time and from time to time upon reasonable prior
notice.

               (d) Upon its receipt of a duly completed Assignment and
Acceptance executed by an assigning Lender and an assignee, the assignee's
completed Administrative Questionnaire (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in paragraph
(b) of this Section and any written consent to such assignment required by
paragraph (b) of this Section, the Administrative Agent shall accept such
Assignment and Acceptance and record the information contained therein in the
Register. No assignment shall be effective for purposes of this Agreement unless
it has been recorded in the Register as provided in this paragraph.

               (e) Any Lender may, without the consent of the Borrowers or the
Administrative Agent, sell participations to one or more banks or other entities
(a "Participant") in all or a portion of such Lender's rights and obligations
under this Agreement (including all or a portion of its Facility A Commitment,
Facility B Commitment or Commitment and the related Loans owing to it); provided
that (i) such Lender's obligations under this Agreement shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations and (iii) the Borrowers, the Administrative
Agent and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement. Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to
enforce this Agreement and to approve any amendment, modification or waiver of
any provision of this Agreement; provided that such agreement or instrument may
provide that such Lender will not, without the consent of the Participant, agree
to any amendment, modification or waiver described in the first proviso to
Section 9.02(b) that affects such Participant. Subject to paragraph (f) of this
Section, the Borrowers agree that each Participant shall be entitled to the
benefits of Sections 2.13, 2.14 and 2.15 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to paragraph (b) of
this Section. To the extent permitted by law, each Participant also shall be
entitled to the

<PAGE>   90

benefits of Section 9.08 as though it were a Lender, provided such Participant
agrees to be subject to Section 2.16(c) as though it were a Lender.

               (f) A Participant shall not be entitled to receive any greater
payment under Section 2.13 or 2.15 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant,
unless the sale of the participation to such Participant is made with the
Borrower's Agent's prior written consent. A Participant that would be a Foreign
Lender if it were a Lender shall not be entitled to the benefits of Section 2.15
unless the Borrower's Agent is notified of the participation sold to such
Participant and such Participant agrees, for the benefit of the Borrowers, to
comply with Section 2.15(e) as though it were a Lender.

               (g) Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement to secure
obligations of such Lender, including any pledge or assignment to secure
obligations to a Federal Reserve Bank, and this Section shall not apply to any
such pledge or assignment of a security interest; provided that no such pledge
or assignment of a security interest shall release a Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender
as a party hereto.

               SECTION 9.05. Survival. All covenants, agreements,
representations and warranties made by the Borrowers herein and in the
certificates or other instruments delivered in connection with or pursuant to
this Agreement shall be considered to have been relied upon by the other parties
hereto and shall survive the execution and delivery of this Agreement and the
making of any Loans, regardless of any investigation made by any such other
party or on its behalf and notwithstanding that the Administrative Agent, any
other Agent or any Lender may have had notice or knowledge of any Default or
incorrect representation or warranty at the time any credit is extended
hereunder, and shall continue in full force and effect as long as the principal
of or any accrued interest on any Loan or any fee or any other amount payable
under this Agreement is outstanding and unpaid and so long as the Commitments
have not expired or terminated. The provisions of Sections 2.13, 2.14, 2.15,
9.03(a) and 9.03(b) and Article VIII shall survive and remain in full force and
effect regardless of the consummation of the transactions contemplated hereby,
the repayment of the Loans, the expiration or termination of the Commitments or
the termination of this Agreement or any provision hereof; provided, that
Sections 2.13, 2.14 and 9.03(a) shall so survive and remain in full force and
effect for up to 90 days after the termination of this Agreement.

               SECTION 9.06. Counterparts; Integration; Effectiveness. This
Agreement may be executed in counterparts

<PAGE>   91

(and by different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a
single contract. This Agreement and any separate letter agreements with respect
to fees payable to the Agents constitute the entire contract among the parties
relating to the subject matter hereof and supersede any and all previous
agreements and understandings, oral or written, relating to the subject matter
hereof. Except as provided in Section 4.01, this Agreement shall become
effective when it shall have been executed by the Administrative Agent and when
the Administrative Agent shall have received counterparts hereof which, when
taken together, bear the signatures of each of the other parties hereto, and
thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart
of a signature page of this Agreement by telecopy shall be effective as delivery
of a manually executed counterpart of this Agreement.

               SECTION 9.07. Severability. Any provision of this Agreement held
to be invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

               SECTION 9.08. Right of Set-off; Certain Agreements With Respect
to Deposit Accounts. (a) If an Event of Default shall have occurred and be
continuing, each Lender and each of its Affiliates is hereby authorized at any
time and from time to time, to the fullest extent permitted by law, to set off
and apply any and all deposits (general or special, time or demand, provisional
or final) at any time held and other obligations at any time owing by such
Lender or Affiliate to or for the credit or the account of any Borrower against
any of and all the obligations of the Borrowers now or hereafter existing under
this Agreement held by such Lender, irrespective of whether or not such Lender
shall have made any demand under this Agreement and although such obligations
may be unmatured. The rights of each Lender under this Section are in addition
to other rights and remedies (including other rights of setoff) which such
Lender may have.

               (b) Each Lender that maintains or at any time hereafter shall
maintain any Cash Sweep Account or any Concentration Account agrees to act as a
subagent of the Collateral Agent for purposes of perfecting the Lien of the
Collateral Agent on such account and all amounts from time to time on deposit
therein. Each such Lender is hereby notified by the Collateral Agent of the
Collateral Agent's security interest in all such accounts and amounts and hereby
acknowledges receipt

<PAGE>   92

of such notice. The Borrowers acknowledge and agree, on their own behalf and on
behalf of the Subsidiaries, that the Collateral Agent, in its own right or
acting through any applicable subagent, shall have full dominion and control
over each such account, subject to the right of each applicable Borrower or
Subsidiary to withdraw funds from such account for purposes permitted hereunder
so long as no Event of Default shall have occurred and be continuing. Each such
Lender agrees that if it shall receive a notice from the Collateral Agent
stating that an Event of Default has occurred and is continuing and directing
such Lender to remit amounts in any such account to the Collateral Agent, it
will thereafter, until such notice shall have been withdrawn, not permit
withdrawals by any Borrower or Subsidiary from such account and will remit all
collected amounts in such account to an account designated by the Collateral
Agent at the end of each Business Day. The Collateral Agent agrees, and the
Lenders acknowledge, that the Collateral Agent shall not exercise its signature
authority in respect of any Cash Sweep Account or any Concentration Account
unless an Event of Default has occurred and is continuing. The Borrowers consent
to the foregoing arrangements and agree that neither the Collateral Agent nor
any Lender shall have any liability to any Borrower or Subsidiary for acting in
accordance therewith.

               SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of
Process. (a) This Agreement shall be construed in accordance with and governed
by the law of the State of New York.

               (b) Each Borrower hereby irrevocably and unconditionally submits,
for itself and its property, to the nonexclusive jurisdiction of the Supreme
Court of the State of New York sitting in New York County and of the United
States District Court of the Southern District of New York, and any appellate
court from any thereof, in any action or proceeding arising out of or relating
to this Agreement, or for recognition or enforcement of any judgment, and each
of the parties hereto hereby irrevocably and unconditionally agrees that all
claims in respect of any such action or proceeding may be heard and determined
in such New York State or, to the extent permitted by law, in such Federal
court. Each of the parties hereto 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 Agreement shall affect any right that the Administrative Agent
or any Lender may otherwise have to bring any action or proceeding relating to
this Agreement against any Borrower or its properties in the courts of any
jurisdiction.

               (c) Each Borrower hereby irrevocably and unconditionally waives,
to the fullest extent it may legally and effectively do so, any objection which
it may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in any court

<PAGE>   93

referred to in paragraph (b) of this Section. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

               (d) Each party to this Agreement irrevocably consents to service
of process in the manner provided for notices in Section 9.01. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

               SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE
TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF
OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

               SECTION 9.11. Headings. Article and Section headings and the
Table of Contents used herein are for convenience of reference only, are not
part of this Agreement and shall not affect the construction of, or be taken
into consideration in interpreting, this Agreement.

               SECTION 9.12. Confidentiality. Each of the Administrative Agent,
the other Agents and the Lenders agrees to maintain the confidentiality of the
Information (as defined below), except that Information may be disclosed (a) to
its and its Affiliates' directors, officers, employees and agents, including
accountants, legal counsel and other advisors (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential
nature of such Information and instructed to keep such Information
confidential), (b) to the extent requested by any regulatory authority, (c) to
the extent required by applicable laws or regulations or by any subpoena or
similar legal process, (d) to any other party to this Agreement, (e) in
connection with the exercise of any remedies hereunder or any suit, action or
proceeding relating to this Agreement or the enforcement of rights hereunder,
(f) subject to an agreement containing provisions substantially the same as
those of this Section, to any assignee of or Participant in, or any prospective
assignee of or Participant in, any of its rights or obligations under this
Agreement, (g) with the written consent of the Borrower's Agent or (h) to the
extent such Information (i) becomes publicly available other than as a result of
a breach of

<PAGE>   94

this Section or (ii) becomes available to the Administrative Agent, any other
Agent or any Lender on a nonconfidential basis from a source other than a
Borrower. For the purposes of this Section, "Information" means all information
received from any Borrower relating to a Borrower or its business, other than
any such information that is available to the Administrative Agent, any other
Agent or any Lender on a nonconfidential basis prior to disclosure by a
Borrower; provided that, in the case of information received from a Borrower
after the date hereof, such information is clearly identified at the time of
delivery as confidential. Any Person required to maintain the confidentiality of
Information as provided in this Section shall be considered to have complied
with its obligation to do so if such Person has exercised the same degree of
care to maintain the confidentiality of such Information as such Person would
accord to its own confidential information.

               SECTION 9.13. Interest Rate Limitation. Notwithstanding anything
herein to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees, charges and other amounts which are treated as interest
on such Loan under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted for, charged,
taken, received or reserved by the Lender holding such Loan in accordance with
applicable law, the rate of interest payable in respect of such Loan hereunder,
together with all Charges payable in respect thereof, shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan but were not payable as a result of the
operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon at the Federal Funds Effective Rate to the date of
repayment, shall have been received by such Lender.

               SECTION 9.14. Conversion of Currencies. (a) If, for the purpose
of obtaining judgment in any court, it is necessary to convert a sum owing
hereunder in one currency into another currency, each party hereto agrees, to
the fullest extent that it may effectively do so, that the rate of exchange used
shall be that at which in accordance with normal banking procedures in the
relevant jurisdiction the first currency could be purchased with such other
currency on the Business Day immediately preceding the day on which final
judgment is given.

               (b) The obligations of each party hereto in respect of any sum
due to any other party hereto or any holder of the obligations owing hereunder
(the "Applicable Creditor") shall, notwithstanding any judgment in a currency
(the "Judgment Currency") other than the currency in which such sum is stated to
be due hereunder (the "Agreement Currency"), be discharged only

<PAGE>   95

to the extent that, on the Business Day following receipt by the Applicable
Creditor of any sum adjudged to be so due in the Judgment Currency, the
Applicable Creditor may in accordance with normal banking procedures in the
relevant jurisdiction purchase the Agreement Currency with the Judgment
Currency; if the amount of the Agreement Currency so purchased is less than the
sum originally due to the Applicable Creditor in the Agreement Currency, such
party agrees, as a separate obligation and notwithstanding any such judgment, to
indemnify the Applicable Creditor against such loss. The obligations of the
parties contained in this Section 9.14 shall survive the termination of this
Agreement and the payment of all other amounts owing hereunder.

               SECTION 9.15. Releases of Collateral. In the event that MTS or
any Subsidiary sells, transfers or otherwise disposes of, or subjects to any
Lien, any assets or property owned by it as permitted by Section 5.13 (and in
accordance with the provisions of this Agreement), or in the event MTS or any
Subsidiary otherwise sells, transfers or disposes of any assets or property
owned by it in a transaction not prohibited by this Agreement (other than to MTS
or an Affiliate of MTS), the Administrative Agent and the Collateral Agent shall
promptly (and the Lenders hereby authorize and instruct the Administrative Agent
and the Collateral Agent to) take such action and execute any such documents as
may be reasonably requested by the Borrowers' Representative to release any
Liens created by any Security Document in respect of such assets or property
and, in the case of a disposition of all or substantially all the equity
interests or assets of any Subsidiary that is a Loan Party, to terminate such
Subsidiary's obligations under the Guarantee Agreement and each other Loan
Document. In addition, the Administrative Agent and the Collateral Agent will
take such actions as are reasonably requested by the Borrower's Representative
to terminate the Liens and security interests created by the Loan Documents when
all the Obligations have been paid in full and the Commitments have been
terminated. The Borrowers agree to pay all out-of-pocket expenses of the
Administrative Agent and the Collateral Agent in connection with releases of
Liens and obligations under the Guarantee Agreement provided for in this
Section.
               SECTION 9.16. Agreement on Bank Transactions. If there is in
effect at any time an Agreement on Bank Transactions between any Lender and
TRKK, the provisions of such Agreement on Bank Transactions shall not apply to
any Loan or other transaction contemplated by this Agreement notwithstanding
anything to the contrary contained in such Agreement on Bank Transactions.

               SECTION 9.17. No Novation. This Agreement shall not extinguish
the Loans outstanding under the Existing Credit Agreement. Nothing herein
contained shall be construed as a

<PAGE>   96

substitution or novation of the Loans outstanding under the Existing Credit
Agreement, which shall remain outstanding as modified hereby. Notwithstanding
any provision of this Agreement, the provisions of Sections 2.15, 2.16, 2.17 and
9.03 of Existing Credit Agreement, each as in effect immediately prior to the
Effective Date, will continue to be effective as to all matters arising out of
or in any way related to facts or events existing or occurring prior to the
Effective Date.

                              EMPLOYMENT AGREEMENT

            THIS EMPLOYMENT AGREEMENT is made and entered into effective May 21,
2001, between SONUS CORP., a Yukon Territory  corporation  ("Corporation"),  and
DANIEL J. KOHL ("Executive").

                                    RECITALS

            A.  Executive  will be Chief  Executive  Officer  and a director  of
Corporation.

            B. Corporation recognizes that the future growth, profitability, and
success of the business of Corporation and its subsidiaries require, and will be
substantially and materially advanced by, the continued employment of Executive.
Corporation desires, therefore, to secure for Corporation and its affiliates the
continued benefit of Executive's experience,  ability, and leadership.  In order
to retain the services of Executive  and to maximize the period of his continued
availability, and in recognition of his continuing contribution to Corporation's
success, Corporation desires to offer Executive the compensation, amenities, and
other benefits that  executives of comparable  experience and ability  generally
receive.

                                    AGREEMENT

            NOW,  THEREFORE,  in  consideration  of  the  mutual  covenants  and
agreements contained herein, the parties agree as follows:

            1. DEFINITIONS.  As used in this Agreement, the following terms have
the meanings set forth in this Section 1:

            "AFFILIATE"   -  Any   person,   firm,   corporation,   association,
organization,  or  unincorporated  trade or business that,  now or  hereinafter,
directly or indirectly,  controls,  is controlled by, or is under common control
with Corporation.

            "BOARD" - The board of directors of Corporation.

            "CAUSE" - Cause for termination of employment means:

                  (i) A material act of fraud or dishonesty by Executive  within
      the course of performing his duties for Corporation or its Affiliates;

                  (ii) Gross  negligence or intentional  misconduct by Executive
      in  performing  material  duties for  Corporation  or its  Affiliates,  or
      unjustifiable  neglect by Executive of the  performance of material duties
      for Corporation or its Affiliates;

                  (iii)  Commission  of an act (or  failure  to take an  action)
      intentionally  against the interest of Corporation or its Affiliates  that
      causes Corporation or an Affiliate material injury; or

                  (iv) An act of serious moral turpitude that causes Corporation
      or an Affiliate material injury.

                                       1
<PAGE>

            Notwithstanding the foregoing,  Executive will not be deemed to have
been terminated for Cause unless and until there has been delivered to Executive
a copy of a resolution duly adopted by the  affirmative  vote of not less than a
majority  of the entire  membership  of the Board  (excluding  Executive),  at a
meeting of the Board called and held for that purpose, finding that, in the good
faith opinion of the Board,  Executive was guilty of conduct  constituting Cause
as defined in this Agreement and specifying the  particulars  thereof in detail.
Executive must have been given reasonable  notice of such meeting and Executive,
together  with his  counsel,  must have been  given an  opportunity  to be heard
before the Board at the meeting.  This  provision will not be deemed to restrict
the  authority,  discretion,  or  power of the  Board,  by any  action  taken in
compliance with  Corporation's  articles of incorporation  and bylaws, to remove
Executive  as an officer or  director  of  Corporation,  with or without  Cause.
Rather,  the foregoing  provisions  merely  define,  for purposes of Executive's
contractual rights and remedies under this Agreement, the circumstances in which
termination of Executive's employment will constitute termination for Cause.

            "CHANGE IN CONTROL" - A change in control of Corporation means:

                  (i) The  acquisition  by any  Person of  beneficial  ownership
      (within the meaning of Rule 13d-3  promulgated  under the Exchange Act) of
      50 percent or more of the combined  voting  power of the then  outstanding
      Voting Securities;  provided, however, that for purposes of this paragraph
      (i), the following  acquisitions  will not constitute a Change of Control:
      (A) any  acquisition  directly from  Corporation,  (B) any  acquisition by
      Corporation,  (C) any acquisition by any employee benefit plan (or related
      trust)   sponsored  or  maintained  by  Corporation  or  any   corporation
      controlled  by  Corporation,   (D)  any  acquisition  by  Warburg,  Pincus
      Ventures, L.P. ("WPV") or by any Person that, now or hereinafter, directly
      or indirectly controls, is controlled by, is under common control with, or
      is  otherwise  an  affiliate  of,  WPV,  or  (E)  any  acquisition  by any
      corporation  pursuant to a  transaction  which  complies with clauses (A),
      (B), and (C) of paragraph (iii) below; or

                  (ii)  individuals  who,  as of the  date  of  this  Agreement,
      constitute  the Board  (the  "Incumbent  Board")  cease for any  reason to
      constitute at least a majority of the Board;  provided,  however, that any
      individual  becoming a director  subsequent to the date of this  Agreement
      whose election, or nomination for election by Corporation's  shareholders,
      was  approved  by a vote of at  least a  majority  of the  directors  then
      comprising  the  Incumbent   Board  will  be  considered  as  though  such
      individual were a member of the Incumbent Board,  but excluding,  for this
      purpose,  any such individual whose initial assumption of office occurs as
      a result of an actual or threatened  election  contest with respect to the
      election  or  removal  of  directors   or  other   actual  or   threatened
      solicitation of proxies or consents by or on behalf of a Person other than
      the Board; or

                  (iii)   consummation   of   a   reorganization,   merger,   or
      consolidation or sale or other  disposition of all or substantially all of
      the assets of Corporation (a "Business Combination") in each case, unless,
      following such Business  Combination,  (A) all or substantially all of the
      individuals  and  entities  who were the  beneficial  owners of the Voting
      Securities  outstanding  immediately  prior to such  Business  Combination
      beneficially  own,  directly  or  indirectly,  more  than 50  percent  of,
      respectively, the then

                                       2
<PAGE>

      outstanding  shares of common stock and the  combined  voting power of the
      then  outstanding  voting  securities  entitled to vote  generally  in the
      election of directors,  as the case may be, of the  corporation  resulting
      from  such  Business  Combination   (including,   without  limitation,   a
      corporation  which as a result of such transaction owns Corporation or all
      or substantially  all of  Corporation's  assets either directly or through
      one or more  subsidiaries) in substantially  the same proportions as their
      ownership,  immediately prior to such Business Combination,  of the Voting
      Securities,  (B) no Person  (excluding WPV, any employee  benefit plan (or
      related  trust) of  Corporation  or such  corporation  resulting from such
      Business  Combination)  beneficially  owns,  directly  or  indirectly,  50
      percent or more of,  respectively,  the then outstanding  shares of common
      stock of the corporation  resulting from such Business  Combination or the
      combined voting power of the then  outstanding  voting  securities of such
      corporation  except to the extent that such ownership existed prior to the
      Business  Combination  and (C) at least a majority  of the  members of the
      board  of  directors  of the  corporation  resulting  from  such  Business
      Combination  were members of Incumbent  Board at the time of the execution
      of the initial  agreement,  or of the action of the Board,  providing  for
      such Business Combination.

            3.1.  Position and Duties.  Executive  agrees to render  services to
Corporation as Chief Executive  Officer and a member of the Board of Corporation
and as an executive  officer of such of Corporation's  Affiliates as the parties
to this Agreement  mutually  agree,  including  Affiliates that may be formed or
acquired  subsequent  to the  Effective  Date.  As Chief  Executive  Officer  of
Corporation,  Executive will have  responsibility  for policy matters  affecting

            3.2. Exclusive Employment.  Executive agrees that during the Term of
this Agreement:

                  (a)  Executive  will  devote  substantially  all  his  regular
      business time (except  during periods of vacation to which he is entitled,
      illness and  approved  leaves of absence)  solely and  exclusively  to the
      business of  Corporation,  whether such  business is operated  directly by
      Corporation or through one or more Affiliates of Corporation;

                  (b) Executive will diligently  carry out his  responsibilities
      under this Agreement;

                  (c) Executive will not,  directly or  indirectly,  without the
      prior approval of the Board, provide services on behalf of any Competitive

      proprietor,   partner,  member,  joint  venturer,  corporate  officer,  or
      director;

                  (d)  Executive  will not  acquire  by reason of  purchase  the

any person to its Board, to appoint any person as an officer of Corporation, and
to remove any officer or director,  including Executive,  in any manner and upon
the basis or bases  presently  or  subsequently  provided for by its articles of
incorporation and bylaws. Nothing in this Agreement will be deemed to constitute
any restriction on the authority,  discretion, or power of the Board, but rather
will only give Executive contractual rights and remedies.

            3.4.  Nondisclosure.  During  and after the Term of this  Agreement,
Executive  agrees not to  disclose  to any  persons  with  interests  adverse or
potentially  adverse  to  Corporation  (other  than  an  employee  or  agent  of
Corporation or any Affiliate entitled to receive such information)  confidential
information  relating  to the  business  of  Corporation  or any  Affiliate  and
obtained by Executive while  providing  services to Corporation or any Affiliate
without  the

                                       5
<PAGE>

consent  of the  Board,  or until the  information  ceases  to be  confidential.
Notwithstanding  the  foregoing,  Executive  will not be  precluded  from making
disclosures  respecting  Corporation or any Affiliate  where the disclosures are
made  pursuant to  compulsory  legal  process or when  otherwise  required by an
appropriate government agency.

            4. COMPENSATION AND BENEFITS.

            4.1. Base Salary. As compensation for the performance of Executive's

Bonus")  in an  amount  (as  determined  by  the  Board)  up to 100  percent  of
Executive's  Base Salary for such fiscal year.  The Annual Bonus for each fiscal
year will be  payable no later than 120 days  following  the end of each  fiscal
year.

            (b) As soon as practible after the Effective Date, Executive will be
paid a one-time signing bonus of $25,000.

            4.3. Stock  Options.  (a) On the Effective  Date,  Executive will be
granted options (the "Options") to purchase 850,000 shares of the  Corporation's
common  stock under the  Corporation's  Stock Award Plan (the "Plan") at a price
equal to the fair market value of the common stock on the  Effective  Date.  The
Options will vest as to 25% of the shares on May 21, 2002,  and thereafter as to
an additional 6 1/4% of the shares on each succeeding three month anniversary of
May 21, 2002 (i.e.,  July 21, 2002,  October 21, 2002,  and so on) until May 21,
2005 (each, a "Vesting Date"),  provided  Executive  continues to be employed by
the Corporation.

            (b) The Options will become immediately and fully exercisable in the
event  that,  within two years  following  a Change in  Control of  Corporation,
Executive is terminated without Cause or the Executive resigns for Good Reason.

            (c) In the event that,  prior to a Change in Control of Corporation,
or more than two years following a Change in Control,  Executive's employment is
terminated by  Corporation  without  Cause or by Executive for Good Reason,  the
Options  will  become  exercisable  as of the  date of such  termination  to the
following extent:

                  (i)   The portion of the Options that become exercisable prior
                        to the Termination Date will remain exercisable; and

                  (ii)  The Options  will  become  fully  exercisable  as of the
                        Termination  Date  as to the sum of (a)  the  number  of
                        shares  that  would  have  become  exercisable  over the
                        twelve  months   following  the  Termination   Date  had
                        Executive's  employment not  terminated,  plus (b) a pro
                        rata  portion  of the  number of shares  that would have

                                       6
<PAGE>

                        become   exercisable   as  of  the  Vesting   Date  next
                        succeeding the date which is twelve months following the
                        Termination  Date,   determined  by  multiplying  53,125
                        (i.e.,  .0625 x  850,000)  by ratio of (I) the number of
                        days elapsed between the  Termination  Date and the last
                        Vesting  Date which  occurred  prior to the  Termination
                        Date, to (II) 91.

            (d) The Options will be subject to terms of the Plan and a customary
award agreement for options granted under the Plan.

            (e)  Vested  Options  will  remain  exercisable  for 90  days  after
termination  of  employment  or,  in the  case of  termination  due to  death or
Disability, for one year.

            4.4. Other Benefits.  During the Term of this  Agreement,  Executive
will be entitled to participate in all Plans (including Plans adopted  following
the  Effective  Date)  covering   Corporation's  key  executive  and  managerial
employees as described in Corporation's employee manual, as amended from time to
time, including,  without limitation,  Plans providing medical,  disability, and
life  insurance  benefits,  and vacation pay. For purposes of the  Corporation's
paid time off policy,  Executive  will be treated as an  employee  with at least
seven years of service.

            4.5.  Expenses.  (a)  Executive is  authorized to incur on behalf of
Corporation, and Corporation will directly pay or will fully reimburse Executive
for all customary and reasonable  out-of-pocket expenses incurred for promoting,
pursuing, or otherwise furthering the business of Corporation or its affiliates.

            (b) During such period as Executive's  permanent residence is not in
the vicinity of  Corporation's  principal  offices,  Corporation  will reimburse
Executive for reasonable  apartment and car rental expenses,  up to a maximum of
$5,000 per month.

            4.6.  Supplemental  Insurance  Benefits.  Corporation will pay up to
$15,000  per  year  during  the  Term  for  premiums  on  supplemental  life and
disability insurance for Executive.

            5. TERMINATION OF AGREEMENT.

            5.1. Death. If Executive dies prior to the expiration of the Term of
this  Agreement,  Corporation  will pay to Executive's  representative  his Base
Salary through the date of death.  All benefits,  including death  benefits,  to
which Executive is then entitled under Plans in which Executive is a participant
will be payable as provided in those Plans.  This Agreement will terminate as of
the date of death and Corporation will have no further  obligations to Executive
under this Agreement.

            5.2. Disability.  In the event Executive becomes Disabled during the
Term,  the  Agreement  will remain in effect and  Executive  will be entitled to
continue to receive the compensation  and benefits  described in Section 4 until
the expiration of the Term with the following modifications:

                                       7
<PAGE>

                  (a) The Annual Bonus,  if any, that otherwise  would be earned
      by Executive for the year in which his  employment is terminated by reason
      of Disability (the "Disability Year") will be prorated based on the number
      of days before and after the Termination Date;

                  (b)  Executive  will not be entitled  to any Annual  Bonus for
      years following the Disability Year; and

                  (c) The amounts  otherwise payable to Executive as Base Salary
      following the Termination  Date will be reduced by the amount,  if any, of
      benefits paid to Executive under  Corporation's Group Long Term Disability
      Insurance  Plan. To the extent  allowable  under  applicable law and other
      Corporation Plans, Executive will be treated as an employee of Corporation
      during the period  after the  Termination  Date and through the end of the
      Term for purposes of this Agreement and the Plans in which  Executive is a
      participant.

            5.3.  Termination  for Cause or Voluntary  Termination  Without Good
Reason.  Pending the  determination by the Board whether or not Cause exists for
termination  of  Executive's  employment  pursuant to the definition of Cause in
Section 1, the Board may suspend Executive or relieve Executive of his duties as
an  officer,   but  may  not  terminate   Executive's   employment.   Upon  such
determination   that  Cause  exists,   Corporation  may  terminate   Executive's
employment.  If  Corporation  terminates  Executive's  employment  for  Cause or
Executive terminates employment other than for Good Reason, Corporation will pay
Executive his Base Salary  through the effective date of such  termination  and,
only if  Corporation  elects,  additional  compensation  equal  to  one-half  of
Executive's  Base Salary for the period during which  Executive is obligated not
to compete  pursuant  to Section  5.7 of this  Agreement.  This  Agreement  will
terminate  as of the  Termination  Date,  and  Corporation  will have no further
obligations to Executive  under this  Agreement.  All accrued  benefits to which
Executive  is then  entitled  under Plans in which he is a  participant  will be
payable as provided in those Plans.

            5.4.  Termination  Without Cause or With Good Reason. If Executive's
employment  with  Corporation  is terminated  (other than for Disability or upon
Executive's  death)  by  Corporation  without  Cause or by  Executive  with Good
Reason,  Corporation  will  pay  Executive  the  following  amounts  ("Severance
Payments"):

                  (a) Executive's Base Salary through the Termination Date; and

                  (b) In lieu of any further  salary  payments to Executive  for
      periods  subsequent  to the  Termination  Date, an amount of severance pay
      (payable in 24 substantially equal monthly installments  commencing on the
      first day of the first  calendar  month  beginning  after the  Termination
      Date) equal to two times the sum of:

                        (i)  Executive's  Base Salary,  at the rate in effect on
                  the Termination Date, and

                        (ii) The average Annual Bonus (if any) paid to Executive
                  or accrued to his benefit (the "Average  Bonus") in respect of
                  the two fiscal

                                       8
<PAGE>

                  years  last  ended  prior  to the  fiscal  year in  which  the
                  Termination   Date  occurs.   For  purposes  of  this  Section
                  5.4(b)(ii),  if the Termination Date is prior to the date that
                  Executive's  Annual  Bonus for the fiscal year ending July 31,
                  2003, has been determined by the Board, the Average Bonus will
                  be the amount of the Annual  Bonus paid to  Executive  for the
                  fiscal year ending July 31, 2002.

            5.5. Related  Benefits.  Except in connection with Executive's death
or  termination  by  Corporation   for  Cause  or  Disability  or  by  voluntary
termination by Executive  without Good Reason,  Corporation  will retain in full
force and effect for the continued  benefit of Executive for two years after the
Termination  Date all  Plans in which  Executive  was  entitled  to  participate
immediately prior to the Termination Date,  provided that Executive's  continued
participation  is possible under the general terms and provisions of such Plans;
provided,  however, that if the participation by Executive in any Plan is barred
by the provisions of such Plan,  Corporation  will arrange to provide  Executive
with benefits  substantially  similar to those to which Executive is entitled to
receive under such Plan (provided,  however, that the cost of such benefits does
not  exceed  125  percent  of the  prevailing  cost of  similar  benefits  under
Corporation's Plans).

            5.6. No  Mitigation.  Executive will not be required to mitigate the
amount of any payment provided for in this Section 5 by seeking other employment
or otherwise.  However, except in the case of a termination of Executive without
Cause or with Good  Reason  within  two years  following  a Change in Control of
Corporation,  the amount of any payment or related benefit  provided for in this
Section 5 will be reduced by any compensation earned or related benefit received
by  Executive  as  a  result  of  either   employment  by  another  employer  or
self-employment   after  the  Termination  Date.  Executive  agrees  to  provide
Corporation with any information reasonably necessary to determine the amount of
such reduction.

            5.7.  Noncompetition  Following Termination.  Executive acknowledges
that the agreements and covenants contained in this Section 5.7 are essential to
protect the value of Corporation's  business and assets and that, by his current
employment  with  Corporation and its  subsidiaries,  Executive has obtained and
will obtain such knowledge,  contacts,  know-how,  training and experience,  and
that such knowledge,  contacts,  know-how, training and experience could be used
to the  substantial  advantage  of a  Competitive  Entity  and to  Corporation's
substantial detriment. Therefore Executive agrees that:

                  (a) In the event Executive's employment is terminated (whether
      by  Corporation  or by Executive)  for any reason before the expiration of
      the  Term,  Executive  will  not,  for a  period  of two  years  from  the
      Termination Date,  participate (as an owner, employee,  officer,  partner,
      member,   shareholder,   director,   consultant,   or  otherwise)  in  any
      Competitive  Entity. The benefits payable under this Agreement,  including
      without  limitation  Corporation's  obligation to pay  Severance  Benefits
      pursuant to Section 5.4 of this Agreement,  and, if Corporation so elects,
      the additional compensation provided in Section 5.3 of this Agreement, are
      in  consideration  of  Executive's  performance  of the  covenants in this
      Section 5.7.

                                       9
<PAGE>

                  (b) Executive  acknowledges that pursuant to the terms of this
      Agreement,  he is  receiving  a "bona  fide  advancement"  in terms of his
      employment with Corporation  within the meaning of ORS 653.295.  Executive
      further  acknowledges  that  he  is  receiving  consideration  under  this
      Agreement  in  addition  to such  consideration  as to  which  he would be
      entitled in the absence of this Agreement,  and he  acknowledges  that his
      agreement to the  provisions of this Section 5.7 is a necessary  condition
      for  Corporation  to enter into this  Agreement and pay the  consideration
      provided for in this Agreement.

                  (c) Executive  acknowledges that  Corporation's  remedy at law
      for a  breach  by him of the  provisions  of  this  Section  5.7  will  be
      inadequate.  Accordingly,  in the event of the breach or threatened breach
      by Executive of any  provision  of this Section 5.7,  Corporation  will be
      entitled to injunctive relief in addition to any other remedy it may have.
      If any of the provisions  of, or covenants  contained in, this Section 5.7
      are   hereafter   construed  to  be  invalid  or   unenforceable   in  any
      jurisdiction,  the same will not affect the remainder of the provisions or
      the enforceability thereof in any other jurisdiction,  which will be given
      full effect,  without regard to the invalidity or unenforceability in such
      other  jurisdiction.  If any of the provisions of, or covenants  contained
      in, this  Section  5.7 are held to be  unenforceable  in any  jurisdiction
      because  of the  duration  or  geographical  scope  of such  provision  or
      covenant,  Executive  and  Corporation  agree that the court  making  such
      determination  will have the power to reduce the duration or  geographical
      scope of such  provision or covenant and that, in its reduced  form,  such
      provision or covenant will be  enforceable;  provided,  however,  that the
      determination  of such court will not  affect the  enforceability  of this
      Section 5.7 in any other jurisdiction.

            6. EFFECT OF CHANGE IN CONTROL. The Severance Benefits payable under
Section 5.4 of this  Agreement are not  conditioned  upon a Change in Control of
Corporation  but are payable upon any  termination  described  in that  Section,
whether or not a Change in Control has occurred. Thus, it is the parties' mutual
intention  that the  Severance  Benefits  are not to be treated as  payments  in
connection with a Change in Control.

            7. SUCCESSORS; BINDING EFFECT.

            7.1.  Corporation.  This Agreement will inure to the benefit of, and
be binding  upon,  any corporate or other  successor or assignee of  Corporation
that acquires, directly or indirectly, by merger,  consolidation or purchase, or
otherwise,  all or  substantially  all the  business  or assets of  Corporation.
Corporation  will  require  any  such  successor,  by an  agreement  in form and
substance reasonably satisfactory to Executive, expressly to assume and agree to
perform this  Agreement in the same manner and to the same extent as Corporation
would be required to perform if no such succession had taken place.

            7.2.  Executive.  This Agreement will inure to the benefit of and be
enforceable  by  Executive's  personal  or  legal  representatives,   executors,
administrators,  successors,  heirs,  distributees,  devisees,  and legatees. If
Executive  should die while any  amount  would  still be  payable  to  Executive
hereunder if Executive had continued to live, all such amounts, unless

                                       10
<PAGE>

otherwise  provided  herein,  will be paid in accordance  with the terms of this
Agreement to Executive's devisee,  legatee, or other designee or, if there is no
such designee, to Executive's estate.

            8. WAIVER AND MODIFICATION.  Any waiver, alteration, or modification
of any of the terms of this  Agreement will be valid only if made in writing and
signed by the parties to this  Agreement.  No waiver by either of the parties of
its rights  under this  Agreement  will be deemed to  constitute  a waiver  with
respect to any  subsequent  occurrences  or  transactions  hereunder  unless the
waiver specifically states that it is to be construed as a continuing waiver.

            9.  GOVERNING  LAW;  SEVERABILITY.  The  validity,   interpretation,
construction,  and  performance  of  this  Agreement  will  be  governed  by and
construed in accordance  with the laws of the state of Oregon.  Any provision of
this Agreement that is prohibited or  unenforceable  will be ineffective only to
the extent of that  prohibition or  unenforceability  without  invalidating  the
remaining provisions of this Agreement.

            10.  NOTICES.  For the purposes of this  Agreement,  notices and all
communications  provided  for in this  Agreement  must be in writing and will be

            12.  ARBITRATION.  Any  dispute or claim that  arises out of or that

this Agreement, must be resolved by mandatory arbitration in accordance with the
then effective  arbitration rules of Arbitration Service of Portland,  Inc., and

with such suit, action, arbitration, and in any appeal. The determination of who

paid to the  prevailing  party will be decided by the  arbitrator or arbitrators

any exceptions made to an arbitration  award submitted to it for confirmation as

proceedings).

            14.  EFFECT  OF  TERMINATION  OF  AGREEMENT.  If this  Agreement  is
terminated,  all rights and benefits that have become vested  hereunder prior to
termination  will remain in full force and effect,  and the  termination  of the
Agreement  will not be construed as relieving any party from the  performance of
any accrued obligation incurred to the other under this Agreement.

entire understanding and agreement of the parties hereto relating to the matters
