March, June, September and December, on the Maturity Date for the calendar
quarter of the Borrower, or portion thereof, then ended.

     Section 2.3. REDUCTION OF COMMITMENT. The Borrower shall have the right at
any time and from time to time upon five (5) Business Days' written notice to
the Administrative Agent to reduce by $5,000,000 or an integral multiple of
$1,000,000 in excess thereof or terminate entirely the unborrowed portion of the
Total Commitment, whereupon the Commitments of the Banks shall be reduced PRO
RATA in accordance with their respective Commitment Percentages of the amount
specified in such notice or, as the case may be, terminated. Promptly after
receiving any notice of the Borrower delivered pursuant to this Section 2.3, the
Administrative Agent will notify the Banks of the substance thereof. No
reduction of the Commitments of the Banks may be reinstated. Notwithstanding the
provisions of Section 2.2(a), upon the effective date of any such termination,
the Borrower shall pay to the Administrative Agent for the respective accounts
of the Banks the full amount of any Facility Fee then accrued and unpaid with
respect to the portion of the Total Commitment so reduced; PROVIDED THAT an
invoice is provided to the Borrower by the Administrative Agent with respect to
such Facility Fee.

     Section 2.4. THE NOTES FOR THE LOANS. The Loans shall be evidenced by
separate promissory notes of the Borrower in substantially the form of EXHIBIT A
hereto (each a "NOTE"), dated the Closing Date and completed with appropriate
insertions. One Note shall be payable to the order of each Bank in a principal
amount equal to such Bank's Commitment or, if less, the outstanding amount of
all Loans made by such Bank, plus interest accrued thereon, as set forth below.
The Borrower irrevocably authorizes each Bank to make or cause to be made, at or
about the time of receipt of any payment of principal on such Bank's Note, an
appropriate notation reflecting such payment on the Note Record attached to such
Bank's Note. The outstanding amount of the Loans set forth on such Note Record
shall be PRIMA FACIE evidence of the principal amount thereof owing and unpaid
to such Bank, but the failure to record, or any error in so recording, any such
amount on such Note Record shall not limit or otherwise affect the obligations
of the Borrower hereunder or under any Note to make payments of principal of or
interest on any Note when due. Upon receipt of any affidavit of any officer of a
Bank as to the loss, theft, destruction or mutilation of its Note and, in the
case of any such loss, theft, destruction or mutilation, upon

<Page>

                                      -15-

cancellation of such Note, the Borrower will issue, in lieu thereof, a
replacement Note in the same principal amount thereof and otherwise of like
tenor.

     Section 2.5. NOTICE AND MATTER OF BORROWING OR CONVERSION OF LOANS; SWING
LINE.

     (a) Whenever the Borrower desires to obtain a Loan hereunder or to convert
an outstanding Loan into a Loan of another type provided for in this Credit
Agreement, the Borrower shall give to the Administrative Agent written notice in
the form of EXHIBIT B hereto (or telephonic notice confirmed in a writing in the
form of EXHIBIT B hereto), which written notice must be received by the
Administrative Agent no later than (i) 11:00 a.m., Boston time, on the day on
which the requested Loan is to be made or converted to a Base Rate Loan, and
(ii) 11:00 a.m., Boston time, on the date two (2) Business Days before the day
on which the requested Loan is to be made or converted to a Eurocurrency Rate
Loan, provided, that any notice requesting a Loan be made or converted to Euros
must comply with the requirements of this Section 2.5(a) and the requirements of
a Euro Notice pursuant to Section 2.7. Each such notice (a "LOAN REQUEST") shall
specify the type of Loan (i.e., Base Rate Loan or Eurocurrency Rate Loan), the
Drawdown Date, or (as the case may be) the date of conversion, and principal
amount of each Loan, stated either in Dollars, or, subject to Section 2.7
hereof, in Euros, or the principal portion thereof to be converted, the interest
rate option to be applicable thereto, and the duration of the applicable
Interest Period, if any (subject in any case to the provisions of the definition
of the term "INTEREST PERIOD") and shall be substantially in the form of EXHIBIT
B; PROVIDED, HOWEVER, that when any Default or Event of Default is continuing,
no Base Rate Loan may be converted into a Eurocurrency Rate Loan.

     (b) Promptly upon receipt of any such Loan Request, the Administrative
Agent shall notify each of the Banks of the substance thereof. Each Loan Request
shall be irrevocable and binding on the Borrower, and shall obligate the
Borrower to accept the Loan of the type requested from the Banks on the proposed
Drawdown Date or (as the case may be) to convert the Loan or a portion thereof
as requested. Each Loan Request shall be in a minimum amount of $3,000,000 (or
the Dollar Equivalent thereof if requested in Euros) or an integral multiple of
$250,000 (or the Dollar Equivalent thereof if requested in Euros) in excess
thereof.

     (c) Notwithstanding the notice and minimum amount requirements set forth in
Section 2.5(a) and (b) but otherwise in accordance with the terms and conditions
of this Credit Agreement, the Administrative Agent may, in its sole discretion
and without conferring with the Banks, make Loans to the Borrower in an
aggregate principal amount not to exceed $20,000,000. The Borrower acknowledges
and agrees that the making of such Loans shall, in each case, be subject in all
respects to the provisions of this Credit Agreement as if they were Loans
covered by a Loan Request including, without limitation, the limitations set
forth in Section 2.1 and the requirements that the applicable provisions of
Section 8 (in the case of Loans made on the Closing Date) and Section 9 be
satisfied. All actions taken by the Administrative Agent pursuant to the
provisions of this Section 2.5(c) shall be conclusive and binding on the
Borrower and the Banks absent the Administrative Agent's gross negligence or
willful misconduct. Loans made pursuant to this Section 2.5(c) shall be Base
Rate Loans until converted in accordance with the provisions of the Credit
Agreement and, prior to a Settlement, such interest shall be for the account of
the Administrative Agent.

     Section 2.6. FUNDS FOR LOANS.

     (a) Not later than 11:00 a.m. (Boston time) on the proposed Drawdown Date
of any Loans, each of the Banks, severally, will make available to the
Administrative Agent, at its head office, or, in the case of Loans in Euros,
such other location as the Administrative Agent may designate from time to time,
in Same Day Funds, the amount of such Bank's Commitment Percentage of the amount
of the requested Loans. Upon receipt from each Bank of such amount, and upon
receipt of the documents required by Section 8 and 9 and the satisfaction of the
other conditions set forth therein, to the extent applicable, the Administrative
Agent will make the aggregate amount of such Loans available to the Borrower.
The failure or refusal of any Bank to make available to the Administrative Agent
at the aforesaid time on any Drawdown Date the amount of its Commitment
Percentage of the requested Loans shall not relieve any other Bank from its
several obligation hereunder to make available to the Administrative Agent the
amount of such Bank's Commitment Percentage of the amount of the requested
Loans.

     (b) The Administrative Agent may (unless notified to the contrary by any
Bank prior to a Drawdown Date) assume that each Bank has made available to the
Administrative Agent on such Drawdown Date the amount of such Bank's Commitment
Percentage of the amount of the requested Loans to be made on such Drawdown
Date, and the Administrative Agent may (but it shall not be required to), in
reliance upon such assumption, make available to the Borrower a corresponding
amount. If any Bank makes available to the Administrative Agent such amount
advanced by the Administrative Agent on a date after such Drawdown Date, such
Bank shall pay to the Administrative Agent on demand an amount equal to the
product of (i) the average computed for the period referred to in clause (iii)
below, of the Overnight Rate for each day included in such period, TIMES (ii)
the amount of such Bank's Commitment Percentage of the amount of such Loans,
TIMES (iii) a fraction, the numerator of which is the number of days that elapse
from and including such Drawdown Date to the date on which the amount of such
Bank's Commitment Percentage of the amount of such Loans shall become
immediately available to the Administrative Agent, and the denominator of which
is 360. If the amount of such Bank's Commitment Percentage of the amount of such
Loans is not made available to the Administrative Agent by such Bank within
three (3) Business Days of such Drawdown Date, the Administrative Agent shall be
entitled to recover such amount from the Borrower on demand, with interest
thereon at the rate per annum applicable to the Loans made on such Drawdown
Date. A statement of the Administrative Agent submitted to any Bank with respect
to any amounts owing under this paragraph shall be PRIMA FACIE evidence of the
amount due and owing to the Administrative Agent by such Bank.

     Section 2.7. EUROS.

     (a) REQUEST FOR EUROS. Subject to the limitations set forth in Section 2.1,
the Borrower may, upon at least four (4) Business Days' notice to the
Administrative Agent on the proposed Drawdown Date thereof) (a "EURO NOTICE"),
request that one or more Loans be made as Eurocurrency Rate Loans in Euros,
PROVIDED that any Loan proposed to be made under this Section 2.7(a) shall be in
an amount not less than the equivalent of $3,000,000 or a greater amount which
is an integral multiple of the equivalent of $250,000 in excess thereof. Each
Euro Notice requesting a Loan in Euros shall be by a Loan Request stating (a)
that the Loan is to be made in Euros and (b) the Borrower's account with the
Administrative Agent to which payment of the

<Page>

                                      -17-

proceeds of such Loan is to be made. If any Bank, on or prior to the second
Business Day preceding the first day of any Interest Period for which a Euro
Notice has been delivered or on any funding date, determines (which
determination shall be conclusive) that the Euro is not freely transferable and
convertible into Dollars or that it will be impracticable for such Bank to fund
the Loan in Euros, then such Bank shall so notify Administrative Agent, which
notification shall be given immediately by the Administrative Agent to the
Borrower, and such Bank's portion of the requested Loan shall, notwithstanding
any contrary election by the Borrower or any other provisions hereof, be
denominated in Dollars as a Eurocurrency Rate Loan with a one month Interest
Period. In the event that the Borrower repays such portion of a Loan denominated
in Dollars as a Eurocurrency Rate Loan, in accordance with Section 2.9 hereof
and such repayment results in Loans outstanding that are not PRO RATA in
accordance with the Commitment Percentages, then all subsequent principal
repayments denominated in Euros which the applicable Bank did not advance shall
be made by the Borrower to the Administrative Agent for the respective accounts
of such Banks other than such Bank on a PRO RATA basis until such time as the
Loans are outstanding on a PRO RATA basis. Subject to the foregoing and to the
satisfaction of the terms and conditions of Sections 8 and 9, each Loan
requested to be made in Euros will be made on the date specified therefor in the
Euro Notice, in Euros and, upon being so made, will have the Interest Period
requested in the Euro Notice.

     (b) EXCHANGE RATE. For purposes of this Credit Agreement the amount in one
currency which shall be equivalent on any particular date to a specified amount
in another currency shall be that amount (as conclusively ascertained by the
Administrative Agent by its normal banking practices, absent manifest error) in
the first currency which is or could be purchased by the Administrative Agent
(in accordance with normal banking practices) with such specified amount in the
second currency in any recognized Eurocurrency Interbank Market selected by the
Administrative Agent in good faith for delivery on such date at the spot rate of
exchange prevailing at 11:00 a.m. (Boston time) (or as soon thereafter as
practicable) on such date (such amount described in this Section 2.7(b), the
"RATE OF EXCHANGE").

     (c) DENOMINATIONS. In the event that any portion of the funds available
under the terms of this Credit Agreement is denominated in Euros, the Dollar
Equivalent of such portion of the funds shall be calculated pursuant to Section
2.7(b) above. The amount so determined shall then be added to the amount already
outstanding in Dollars for the purpose of determining the remaining availability
of funds under Section 2.1 and Section 2.7(a) hereof and any required repayments
under the following Section 2.9(d).

     (d) REPAYMENT. If at any time prior to the Maturity Date, the Dollar
Equivalent of the aggregate principal amount outstanding of all Loans, Unpaid
Reimbursement Obligations and the Maximum Drawing Amount hereunder on the last
day of any calendar quarter shall exceed the Total Commitment as a result of
fluctuations in respective conversion rates, the Borrower shall pay or cause to
be paid immediately, upon demand made by the Administrative Agent, such amounts
as are sufficient to eliminate such excess and to reduce the Dollar Equivalent
of such aggregate principal amount outstanding to the Total Commitment. In the
event there are any Loans outstanding which are denominated in Euros, the
Administrative Agent shall provide the Banks and the Borrower with calculations
on the last day of each calendar quarter that such Loans are outstanding as to
the Dollar Equivalents of such Loans.

<Page>

                                      -18-

     (e) FUNDING. Each Bank may make any Eurocurrency Rate Loan denominated in
Euros by causing any of its domestic or foreign branches or foreign affiliates
to make such Eurocurrency Rate Loan (whether or not such branch or affiliate is
named as a lending office on the signature pages hereof); PROVIDED that in such
event the obligation of the Borrower to repay such Eurocurrency Rate Loan shall
nevertheless be to such Bank and shall, for all purposes of this Credit
Agreement (including without limitation for purposes of the definition of the
term "MAJORITY BANKS") be deemed made by such Bank, to the extent of such
Eurocurrency Rate Loan, for the account of such branch or affiliate.

     Section 2.8. MANDATORY REPAYMENTS OF LOANS. The Borrower promises to pay
the outstanding amount of all Loans on the earlier to occur of a Change in
Control or the Maturity Date. In addition, if at any time the outstanding amount
of the Loans, the Maximum Drawing Amount and all Unpaid Reimbursement
Obligations exceeds the Total Commitment at such time, then the Borrower shall
immediately pay the amount of such excess to the Administrative Agent for
application: first, to any Unpaid Reimbursement Obligations; second, to the
Loans; and third, to provide to the Administrative Agent cash collateral for
Reimbursement Obligations as contemplated by Section 2A.2(b) and (c). Each
payment of any Unpaid Reimbursement Obligations or prepayment of Loans shall be
allocated among the Banks, in proportion, as nearly as practicable, to each
Reimbursement Obligation or (as the case may be) the respective unpaid principal
amount of each Banks' Note, with adjustments to the extent practicable to
equalize any prior payments or repayments not exactly in proportion.

     Section 2.9. OPTIONAL REPAYMENTS OF LOANS. The Borrower shall have the
right, at its election, to repay the outstanding amount of any Loans, as a whole
or in part, at any time without penalty or premium; PROVIDED that in the case of
any full or partial prepayment of the outstanding amount of any Loans prior to
the end of the Interest Period applicable thereto, the Borrower shall be
obligated to reimburse the Banks in respect thereof pursuant to Section 3.3. The
Borrower shall give the Administrative Agent, no later than 11:00 a.m. (Boston
time), at least two (2) Business Days' notice of any proposed repayment of Loans
denominated in Dollars or three (3) Business Days' notice of any proposed
repayment of Loans denominated in Euros, in each case specifying the proposed
date of repayment and the principal amount to be paid, which notice, if not in
writing, shall be promptly confirmed in writing. Each such partial payment of
Loans shall be in a minimum amount of $5,000,000 (or the Dollar Equivalent
thereof if in Euros) or an integral multiple of $1,000,000 (or the Dollar
Equivalent thereof if in Euros) in excess thereof. Each repayment pursuant to
this Section 2.9 shall be accompanied by the payment of accrued interest on the
principal repaid to the date of payment. Each such partial repayment of Loans
shall be allocated among the Banks, in proportion, as nearly as practicable, to
the respective unpaid principal amount of each Bank's Note, with adjustments to
the extent practicable to equalize any prior repayments not exactly in
proportion.

     Section 2.10. SETTLEMENTS.

     (a) GENERAL. On each Settlement Date, the Administrative Agent shall, not
later than 11:00 a.m. (Boston time), give telephonic or facsimile notice (a) to
the Banks and the Borrower of the respective outstanding amount of Loans made by
the Administrative Agent on behalf of the Banks from the immediately preceding
Settlement Date through the close of business on the prior day and the amount of
any Eurocurrency Rate Loans to be made (following the giving of

<Page>

                                      -19-

notice pursuant to Section 2.5(a)(ii)) on such date pursuant to a Loan Request
and (b) to the Banks of the amount (a "SETTLEMENT AMOUNT") that each Bank (a
"SETTLING BANK") shall pay to effect a Settlement of any Loan. A statement of
the Administrative Agent submitted to the Banks and the Borrower or to the Banks
with respect to any amounts owing under this Section 2.10 shall be PRIMA FACIE
evidence of the amount due and owing. Each Settling Bank shall, not later than
3:00 p.m. (Boston time) on such Settlement Date, effect a wire transfer of Same
Day Funds to the Administrative Agent in the amount of the Settlement Amount for
such Settling Bank. All funds advanced by any Bank as a Settling Bank pursuant
to this Section 2.10 shall for all purposes be treated as a Loan made by such
Settling Bank to the Borrower and all funds received by any Bank pursuant to
this Section 2.10 shall for all purposes be treated as repayment of amounts owed
with respect to Loans made by such Bank. In the event that any bankruptcy,
reorganization, liquidation, receivership or similar cases or proceedings in
which the Borrower is a debtor prevents a Settling Bank from making any Loan to
effect a Settlement as contemplated hereby, such Settling Bank will make such
dispositions and arrangements with the other Banks with respect to such Loans,
either by way of purchase of participations, distribution, PRO TANTO assignment
of claims, subrogation or otherwise as shall result in each Bank's share of the
outstanding Loans being equal, as nearly as may be, to such Bank's Commitment
Percentage of the outstanding amount of the Loans.

     (b) FAILURE TO MAKE FUNDS AVAILABLE. The Administrative Agent may, unless
notified to the contrary by any Settling Bank prior to a Settlement Date, assume
that such Settling Bank has made or will make available to the Administrative
Agent on such Settlement Date the amount of such Settling Bank's Settlement
Amount, and the Administrative Agent may (but it shall not be required to), in
reliance upon such assumption, make available to the Borrower a corresponding
amount. If any Settling Bank makes available to the Administrative Agent such
amount on a date after such Settlement Date, such Settling Bank shall pay to the
Administrative Agent on demand an amount equal to the product of (i) the average
computed for the period referred to in clause (iii) below, of the Overnight Rate
for each day included in such period, TIMES (ii) the amount of such Settlement
Amount, TIMES (iii) a fraction, the numerator of which is the number of days
that elapse from and including such Settlement Date to the date on which the
amount of such Settlement Amount shall become immediately available to the
Administrative Agent, and the denominator of which is 360. A statement of the
Administrative Agent submitted to such Settling Bank with respect to any amounts
owing under this Section 2.10(b) shall be prima facie evidence of the amount due
and owing to the Administrative Agent by such Settling Bank. If such Settling
Bank's Settlement Amount is not made available to the Administrative Agent by
such Settling Bank within three (3) Business Days following such Settlement
Date, the Administrative Agent shall be entitled to recover such amount from the
Borrower on demand, with interest thereon at the rate per annum applicable to
the Loans as of such Settlement Date.

     (c) NO EFFECT ON OTHER BANKS. The failure or refusal of any Settling Bank
to make available to the Administrative Agent at the aforesaid time and place on
any Settlement Date the amount of such Settling Bank's Settlement Amount shall
not (a) relieve any other Settling Bank from its several obligations hereunder
to make available to the Administrative Agent the amount of such other Settling
Bank's Settlement Amount or (b) impose upon any Bank, other than the Settling
Bank so failing or refusing, any liability with respect to such failure or
refusal or otherwise increase the Commitment of such other Bank.

     Section 2A.1. LETTER OF CREDIT COMMITMENTS.

     (a) COMMITMENT TO ISSUE LETTERS OF CREDIT. Subject to the terms and
conditions hereof and the execution and delivery by the Borrower of a letter of
credit application on the Administrative Agent's customary form (a "LETTER OF
CREDIT APPLICATION"), the Administrative Agent on behalf of the Banks and in
reliance upon the agreement of the Banks set forth in Section 2A.1(d) and upon
the representations and warranties of the Borrower contained herein, agrees, in
its individual capacity, to issue, extend and renew for the account of the
Borrower one or more standby or documentary letters of credit (individually, a
"LETTER OF CREDIT"), in such form as may be requested from time to time by the
Borrower and agreed to by the Administrative Agent; PROVIDED, HOWEVER, that,
after giving effect to such request, (i) the sum of the aggregate Maximum
Drawing Amount and all Unpaid Reimbursement Obligations shall not exceed
$50,000,000 at any one time and (ii) the sum of (A) the Maximum Drawing Amount
on all Letters of Credit, (B) all Unpaid Reimbursement Obligations, and (C) the
Dollar Equivalent of the amount of all Loans outstanding shall not exceed the
Total Commitment at such time.

     (b) LETTER OF CREDIT APPLICATIONS. Each Letter of Credit Application shall
be completed to the satisfaction of the Administrative Agent. In the event that
any provision of any Letter of Credit Application shall be inconsistent with any
provision of this Credit Agreement, then the provisions of this Credit Agreement
shall, to the extent of any such inconsistency, govern.

     (c) TERMS OF LETTERS OF CREDIT. Each Letter of Credit issued, extended or
renewed hereunder shall, among other things, (i) provide for the payment of
sight drafts for honor thereunder when presented in accordance with the terms
thereof and when accompanied by the documents described therein, and (ii) have
an expiry date no later than the date which is fourteen (14) days (or, if the
Letter of Credit is confirmed by a confirmer or otherwise provides for one or
more nominated persons, forty-five (45) days) prior to the Maturity Date. Each
Letter of Credit so issued, extended or renewed shall be subject to the Uniform
Customs and Practice for Documentary Credits (1993 Revision), International
Chamber of Commerce Publication No. 500 or any successor version thereto adopted
by the Administrative Agent in the ordinary course of its business as a letter
of credit issuer and in effect at the time of issuance of such Letter of Credit
(the "UNIFORM CUSTOMS") or, in the case of a standby Letter of Credit, either
the Uniform Customs or the International Standby Practices (ISP98),
International Chamber of Commerce Publication No. 590, or any successor code of
standby letter of credit practices among banks adopted by the Administrative
Agent in the ordinary course of its business as a standby letter of credit
issuer and in effect at the time of issuance of such Letter of Credit.

     (d) REIMBURSEMENT OBLIGATIONS OF BANKS. Each Bank severally agrees that it
shall be absolutely liable, without regard to the occurrence of any Default or
Event of Default or any other condition precedent whatsoever, to the extent of
such Bank's Commitment Percentage, to reimburse the Administrative Agent on
demand for the amount of each draft paid by the Administrative Agent under each
Letter of Credit to the extent that such amount is not reimbursed by the
Borrower pursuant to Section 2A.2 (such agreement for a Bank being called herein
the "LETTER OF CREDIT PARTICIPATION" of such Bank).

<Page>

                                      -21-

     (e) PARTICIPATIONS OF BANKS. Each such payment made by a Bank shall be
treated as the purchase by such Bank of a participating interest in the
Borrower's Reimbursement Obligation under Section 2A.2 in an amount equal to
such payment. Each Bank shall share in accordance with its participating
interest in any interest which accrues pursuant to Section 2A.2.

     Section 2A.2. REIMBURSEMENT OBLIGATIONS OF THE BORROWER. In order to induce
the Administrative Agent to issue, extend and renew each Letter of Credit and
the Banks to participate therein, the Borrower hereby agrees to reimburse or pay
to the Administrative Agent, for the account of the Administrative Agent or (as
the case may be) the Banks, with respect to each Letter of Credit issued,
extended or renewed by the Administrative Agent hereunder,

     (a) except as otherwise expressly provided in Section 2A.2(b) and (c), on
each date that any draft presented under such Letter of Credit is honored by the
Administrative Agent, or the Administrative Agent otherwise makes a payment with
respect thereto, (i) the amount paid by the Administrative Agent under or with
respect to such Letter of Credit, and (ii) the amount of any taxes, fees,
charges or other costs and expenses whatsoever incurred by the Administrative
Agent or any Bank in connection with any payment made by the Administrative
Agent or any Bank under, or with respect to, such Letter of Credit,

     (b) upon the reduction (but not termination) of the Total Commitment to an
amount less than the Maximum Drawing Amount, an amount equal to such difference,
which amount shall be held by the Administrative Agent for the benefit of the
Banks and the Administrative Agent as cash collateral for all Reimbursement
Obligations, and

     (c) upon the termination of the Total Commitment, or the acceleration of
the Reimbursement Obligations with respect to all Letters of Credit in
accordance with Section 10, an amount equal to the then Maximum Drawing Amount
on all Letters of Credit, which amount shall be held by the Administrative Agent
for the benefit of the Banks and the Administrative Agent as cash collateral for
all Reimbursement Obligations.

     Each such payment shall be made to the Administrative Agent at the
Administrative Agent's Office in immediately available funds. Interest on any
and all amounts remaining unpaid by the Borrower under this Section 2A.2 at any
time from the date such amounts become due and payable (whether as stated in
this Section 2A.2, by acceleration or otherwise) until payment in full (whether
before or after judgment) shall be payable to the Administrative Agent on demand
at the rate specified in Section 3.11 for overdue principal on the Loans.

     Section 2A.3. LETTER OF CREDIT PAYMENTS. If any draft shall be presented or
other demand for payment shall be made under any Letter of Credit, the
Administrative Agent shall notify the Borrower of the date and amount of the
draft presented or demand for payment and of the date and time when it expects
to pay such draft or honor such demand for payment. If the Borrower fails to
reimburse the Administrative Agent as provided in Section 2A.2 on or before the
date that such draft is paid or other payment is made by the Administrative
Agent, the Administrative Agent may at any time thereafter notify the Banks of
the amount of any such Unpaid Reimbursement Obligation. No later than 3:00 p.m.
(Boston time) on the Business Day next following the receipt of such notice,
each Bank shall make available to the Administrative Agent, at the
Administrative Agent's Office, in immediately available funds, such Bank's
Commitment

<Page>

                                      -22-

Percentage of such Unpaid Reimbursement Obligation, together with an amount
equal to the product of (a) the average, computed for the period referred to in
clause (c) below, of the Overnight Rate for each day included in such period,
TIMES (b) the amount equal to such Bank's Commitment Percentage of such Unpaid
Reimbursement Obligation, TIMES (c) a fraction, the numerator of which is the
number of days that elapse from and including the date the Administrative Agent
paid the draft presented for honor or otherwise made payment to the date on
which such Bank's Commitment Percentage of such Unpaid Reimbursement Obligation
shall become immediately available to the Administrative Agent, and the
denominator of which is 360. The responsibility of the Administrative Agent to
the Borrower and the Banks shall be only to exercise reasonable care and to
determine that the documents (including each draft) delivered under each Letter
of Credit in connection with such presentment shall be in conformity in all
material respects with such Letter of Credit.

     Section 2A.4. OBLIGATIONS ABSOLUTE. The Borrower's obligations under this
Section 2A shall be absolute and unconditional under any and all circumstances
and irrespective of the occurrence of any Default or Event of Default or any
condition precedent whatsoever or any setoff, counterclaim or defense to payment
which the Borrower may have or have had against the Administrative Agent, any
Bank or any beneficiary of a Letter of Credit. The Borrower further agrees with
the Administrative Agent and the Banks that the Administrative Agent and the
Banks shall not be responsible for, and the Borrower's Reimbursement Obligations
under Section 2A.2 shall not be affected by, among other things, the validity or
genuineness of documents or of any endorsements thereon, even if such documents
should in fact prove to be in any or all respects invalid, fraudulent or forged,
or any dispute between or among the Borrower, the beneficiary of any Letter of
Credit or any financing institution or other party to which any Letter of Credit
may be transferred or any claims or defenses whatsoever of the Borrower against
the beneficiary of any Letter of Credit or any such transferee. The
Administrative Agent and the Banks shall not be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Letter of Credit. The
Borrower agrees that any action taken or omitted by the Administrative Agent or
any Bank under or in connection with each Letter of Credit and the related
drafts and documents, if done in good faith, shall be binding upon the Borrower
and shall not result in any liability on the part of the Administrative Agent or
any Bank to the Borrower.

     Section 2A.5. RELIANCE BY ISSUER. To the extent not inconsistent with
Section 2A.4, the Administrative Agent shall be entitled to rely, and shall be
fully protected in relying upon, any Letter of Credit, draft, writing,
resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex or teletype message, statement, order or other
document believed by it to be genuine and correct and to have been signed, sent
or made by the proper Person or Persons and upon advice and statements of legal
counsel, independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Credit Agreement unless it
shall first have received such advice or concurrence of the Majority Banks as it
reasonably deems appropriate or it shall first be indemnified to its reasonable
satisfaction by the Banks against any and all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action. The
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Credit Agreement in accordance with a request
of the Majority Banks, and

<Page>

                                      -23-

such request and any action taken or failure to act pursuant thereto shall be
binding upon the Banks and all future holders of the Notes or of a Letter of
Credit Participation.

     Section 2A.6. LETTER OF CREDIT FEE. The Borrower shall pay a fee (in each
case, a "LETTER OF CREDIT FEE") to the Administrative Agent in respect of each
Letter of Credit in (a) an amount equal to the per annum rate set forth on
Schedule 1.2 in the applicable row headed Margin Percentage beneath the column
for the Debt Rating in effect for such date on the undrawn face amount of such
Letter of Credit for the accounts of the Banks in accordance with their
respective Commitment Percentages and (b) an amount equal to one-tenth of one
percent (0.10%) per annum on the undrawn face amount of such Letter of Credit
for the account of the Administrative Agent as a fronting fee. The accrued
Letter of Credit Fee shall be payable, quarterly in arrears, on the last day of
each March, June, September and December and on the Maturity Date for the
calendar quarter, or portion thereof, then ended. In respect of each Letter of
Credit, the Borrower shall also pay to the Administrative Agent for the
Administrative Agent's own account, at such other time or times as such charges
are customarily made by the Administrative Agent, the Administrative Agent's
customary issuance, amendment, negotiation or document examination and other
administrative fees as in effect from time to time.

     Section 3. INTEREST; CERTAIN GENERAL PROVISIONS.

     Section 3.1. INTEREST ON LOANS; PAYMENTS OF INTEREST.

     (a) Except as otherwise provided by Section 3.11 hereof, each Base Rate
Loan shall bear interest on the outstanding principal amount thereof at a rate
per annum equal to the Base Rate in effect from time to time, which rate shall
change contemporaneously with any change in the Base Rate.

     (b) Except as otherwise provided by Section 3.11 hereof, each Eurocurrency
Rate Loan shall bear interest on the outstanding principal amount thereof, for
each Interest Period applicable thereto, at a rate per annum equal to the
Eurocurrency Rate determined for such Interest Period, PLUS the applicable
Margin Percentage as in effect on the first day of such Interest Period.

     (c) The Borrower absolutely and unconditionally promises to pay all
interest accrued on each Loan in arrears on each Interest Payment Date with
respect thereto. Interest on Loans made in Dollars shall be paid in Dollars and
interest on Loans made in Euros shall be paid in Euros.

     Section 3.2. INTEREST PERIOD OPTIONS. Upon notice (a "CONTINUATION
REQUEST") given to the Administrative Agent no later than 11:00 a.m. (Boston
time) at least two (2) Business Days', or in the case of Eurocurrency Rate Loans
in Euros, four (4) Business Days', prior to the expiration of an Interest Period
applicable to any Eurocurrency Rate Loan, the Borrower may elect to continue
such Eurocurrency Rate Loan upon the expiration of the then applicable Interest
Period for another Interest Period of the duration specified in such notice;
PROVIDED, HOWEVER, that no Eurocurrency Rate Loan may be continued for an
Interest Period in excess of seven (7) days when any Default or Event of Default
is continuing; and PROVIDED FURTHER that the Eurocurrency Rate Loans to which a
particular Interest Period applies shall be in an aggregate principal amount of
$3,000,000 (or the equivalent thereof if requested in Euros) or an integral
multiple of

<Page>

                                      -24-

$250,000 (or the equivalent thereof if requested in Euros) in excess thereof.
Each continuation of a Eurocurrency Rate Loan hereunder shall be allocated
between the Banks in proportion, as nearly as practicable, to such Bank's
Commitment Percentage or Commitment Percentage (as the case may be), with
adjustments to the extent practicable to equalize any prior continuations not
exactly in proportion.

     Section 3.3. INDEMNITY. The Borrower agrees to indemnify each Bank and to
hold each Bank harmless from any loss or expense that such Bank may sustain or
incur as a consequence of (a) default by the Borrower in payment of the
principal amount of or interest on any Loans, including any such loss or expense
arising from interest or fees payable by such Bank to lenders of funds obtained
by it in order to maintain its Loans, (b) default by the Borrower in making a
borrowing after the Borrower has given (or is deemed to have given) a Loan
Request or a Continuation Request in accordance with Sections 2.5 or 3.2 other
than as a result of a default by any Bank, (c) the making of any payment of a
Loan on a day that is not the last day of the applicable Interest Period with
respect thereto, including interest or fees payable by any Bank to lenders of
funds obtained by it in order to maintain any such Loan, to the extent not
off-set by income derived from the redeployment of such funds or (d) default by
the Borrower in making any repayment of a Loan after the Borrower has given a
notice in accordance with Section 2.9. This covenant shall survive the
termination of this Credit Agreement and payment of the Notes.

     Section 3.4. FUNDS FOR PAYMENTS. All payments of principal, interest on
Loans made to the Borrower which are denominated in Dollars, and all
Reimbursement Obligations, Facility Fees, Utilization Fees, Letter of Credit
Fees and any other amounts due hereunder or under any of the other Loan
Documents shall be made on the due date thereof by the Borrower to the
Administrative Agent at the Administrative Agent's office at 100 Federal Street,
Boston, Massachusetts 02110 or at such other location in the Boston,
Massachusetts area that the Administrative Agent may from time to time designate
in writing (the "ADMINISTRATIVE AGENT'S OFFICE"), in each case in Dollars in
Same Day Funds. All payments of principal and interest on Loans made to the
Borrower which are denominated in Euros shall be made by the Borrower at a
depository designated by the Administrative Agent in a country in which Euros
are legal tender, in each case in Euros and in Same Day Funds. Each payment in
respect of any Loan made by the Borrower shall be made in the same currency in
which such Loan was made unless otherwise agreed by the Banks. All payments by
the Borrower hereunder and under any of the other Loan Documents shall be made
without setoff or counterclaim and free and clear of and without deduction for
any taxes, levies, imposts, duties, charges, fees, deductions, withholdings,
compulsory loans, restrictions or conditions of any nature now or hereafter
imposed or levied by any jurisdiction or any political subdivision thereof or
taxing or other authority therein unless the Borrower is compelled by law to
make such deduction or withholding. If any such obligation is imposed upon the
Borrower with respect to any amount payable by it hereunder or under any of the
other Loan Documents, the Borrower will pay to the Administrative Agent, for the
account of the Banks or (as the case may be) the Administrative Agent, on the
date on which such amount is due and payable hereunder or under such other Loan
Document, such additional amount in Dollars as shall be necessary to enable the
Banks or the Administrative Agent to receive the same net amount which the Banks
or the Administrative Agent would have received on such due date had no such
obligation been imposed upon the Borrower. The Borrower will deliver promptly to
the Administrative Agent certificates or other valid vouchers for all taxes or
other charges deducted from or paid with respect to payments made by the
Borrower hereunder or

<Page>

                                      -25-

under such other Loan Document. The Borrower may, within 90 days of the
imposition of any such obligation by any Bank, by notice in writing to the
Administrative Agent and such Bank, (a) require such Bank that imposed such
obligation to cooperate with the Borrower in obtaining an Eligible Assignee
satisfactory to the Administrative Agent as a replacement bank for such Bank and
in assigning such Bank's interest hereunder and under its Note to such Eligible
Assignee subject to the terms, conditions, and procedures of Section 15, or (b)
repay all amounts owed to such Bank, terminate such Bank's Commitments and
reduce the aggregate of the Commitments under the Credit Agreement by a
corresponding amount. Each Bank that is not incorporated or organized under the
laws of the United States of America or a state thereof or the District of
Columbia agrees that, on an annual basis, it will deliver to the Borrower and
the Administrative Agent two duly completed copies of United States Internal
Revenue Service Form W-8BEN or W-8ECI or successor applicable form, as the case
may be, certifying in each case that such Bank is entitled to receive payments
under this Credit Agreement and the Note payable to it, without deduction or
withholding of any United States federal income taxes.

     Section 3.5. COMPUTATIONS. All computations of interest on Eurocurrency
Rate Loans, the Facility Fee, the Letter of Credit Fees and the Utilization Fee
shall be based on a 360 day year and paid for the actual number of days elapsed.
All computations of interest on Base Rate Loans shall be based on a 365 day year
and paid for the actual number of days elapsed. Except as otherwise specifically
provided herein, whenever a payment hereunder or under any of the other Loan
Documents becomes due on a day that is not a Business Day, the due date for such
payment shall be extended to the next succeeding Business Day, and interest
shall accrue during such extension. The outstanding amount of the Loans as
reflected on the Note Records from time to time shall be considered conclusive
and binding absent manifest mathematical error on the Borrower unless within
thirty (30) Business Days after receipt of any notice by the Administrative
Agent or any of the Banks of such outstanding amount, the Borrower shall notify
the Administrative Agent or such Bank to the contrary.

     Section 3.6. INABILITY TO DETERMINE EUROCURRENCY RATE. In the event the
Administrative Agent shall determine that adequate and reasonable methods do not
exist for ascertaining the Eurocurrency Rate that would otherwise determine the
rate of interest to be applicable during any Interest Period, the Administrative
Agent shall forthwith give telex notice of such determination (which shall be
conclusive and binding on the Borrower) to the Borrower at least one (1)
Business Day before the first day of such Interest Period. In such event, (a)
any Loan Request or Continuation Request with respect to Loans shall be
automatically withdrawn, (b) the Borrowers and the Banks shall negotiate in good
faith to agree on an alternative interest rate which is reasonably equivalent to
the Eurocurrency Rate; PROVIDED that if the Borrowers and the Banks are unable
to agree on such alternative interest rate prior to the last day of the then
current Interest Period, each Loan, if denominated in Dollars, then outstanding
will as of the last day of the then current Interest Period bear interest at a
per annum rate equal to the Base Rate in effect from time to time payable in
arrears on the last day of each fiscal quarter of the Borrower, and, if
denominated in Euros, will automatically, on the last day of the then current
Interest Period, be repaid, and (c) the obligations of the Banks to make
additional Loans shall be suspended until the Administrative Agent determines
that the circumstances giving rise to such suspension no longer exist, whereupon
the Administrative Agent shall so notify the Borrower and the Banks.

                                      -26-

     Section 3.7. ILLEGALITY. Notwithstanding any other provisions herein, if
any introduction of or change in any law, regulation, treaty or directive or in
the interpretation or application thereof shall make it unlawful, or any central
bank or other governmental authority having jurisdiction over any Bank or its
Eurocurrency Lending Office shall assert that it is unlawful, for such Bank or
its Eurocurrency Lending Office to make or maintain Loans that bear interest
calculated by reference to the Eurocurrency Rate, (a) such Bank shall forthwith
give notice by telefax of such circumstances, confirmed in a writing delivered
to the Borrower by courier or postal service (which notice shall be withdrawn by
such Bank when such Bank shall reasonably determine that it shall no longer be
illegal for such Bank or its Eurocurrency Lending Office to make or maintain
such Loans), (b) the commitment of such Bank to make or maintain Loans shall
forthwith be cancelled and (c) such Bank's Loans then outstanding, if any, shall
be converted automatically on the next succeeding last day of each Interest
Period applicable to such Loans or within such earlier period as may be required
by law to Loans which bear interest at a per annum rate equal to an alternative
interest rate which is reasonably equivalent to the Eurocurrency Rate upon which
the Administrative Agent and the Banks may in good faith agree; PROVIDED that if
the Borrower and the Banks are unable to agree on such alternative interest
rate, such Loans, if denominated in Dollars, shall bear interest at a per annum
rate equal to the Base Rate in effect from time to time payable in arrears on
the last day of each fiscal quarter of the Borrower, and, if denominated in
Euros, will automatically, on the last day of the then current Interest Period,
be repaid. The Borrower agrees promptly to pay the Administrative Agent for the
account of each Bank, upon demand by the Administrative Agent, any additional
amounts necessary to compensate the Banks for any costs incurred by the Banks in
making any conversion in accordance with this Section 3.7, including any
interest or fees payable by the Banks to lenders of funds obtained by them in
order to make or maintain their Loans (the Administrative Agent's written notice
of such costs, as certified to the Borrower, to be conclusive absent manifest
error).

     Section 3.8. ADDITIONAL COSTS, ETC. If any present or future, or any change
in any present or future, applicable law, which expression, as used herein,
includes statutes, rules and regulations thereunder and interpretations thereof
by any competent court or by any governmental or other regulatory body or
official charged with the administration or the interpretation thereof and
requests, directives, instructions and notices at any time or from time to time
hereafter made upon or otherwise issued to any Bank by any central bank or other
fiscal, monetary or other authority (whether or not having the force of law),
shall:

     (a) subject any Bank to any tax, levy, impost, duty, charge, fee, deduction
or withholding of any nature with respect to this Credit Agreement, the other
Loan Documents, any Letters of Credit, such Bank's Commitment or the Loans
advanced by such Bank (other than taxes based upon or measured by the income or
profits of such Bank), or

     (b) materially change the basis of taxation (except for changes in taxes on
income or profits) of payments to any Bank of the principal of or the interest
on any Loans or any other amounts payable to such Bank under this Credit
Agreement or the other Loan Documents, or

     (c) impose or increase or render applicable (other than to the extent
specifically provided for elsewhere in this Credit Agreement) any special
deposit, reserve, assessment, liquidity, or other similar requirements against
assets held by, or deposits in or for the account of, or loans by, or
commitments of, or letters of credit issued by, an office of any Bank, or

<Page>

                                      -27-

     (d) impose on any Bank any other conditions or requirements with respect to
this Credit Agreement, the other Loan Documents, any Letters of Credit, the
Loans, such Bank's Commitment or any class of loans or commitments of which any
of the Loans or such Bank's Commitment forms a part;

and the result of any of the foregoing is

         (i) to increase the cost to any Bank of making, funding, issuing,
     renewing, extending or maintaining the Loans, any Letter of Credit or such
     Bank's Commitment, or

         (ii) to reduce the amount of principal, interest or other amounts
     payable to such Bank hereunder on account of such Bank's Commitment, the
     Loans or any Letter of Credit, or

         (iii) to require such Bank to make any payment or to forego any
     interest or Reimbursement Obligation or other sum payable hereunder, the
     amount of which payment or foregone interest or Reimbursement Obligation or
     other sum is calculated by reference to the gross amount of any sum
     receivable or deemed received by such Bank from the Borrower hereunder,

then, and in each such case, the Borrower will, upon written demand made by such
Bank at any time and from time to time and as often as the occasion therefor may
arise, pay to such Bank such additional amounts as will be sufficient to
compensate such Bank for such additional cost, reduction, payment or foregone
interest or Reimbursement Obligation or other sum (after such Bank shall have
allocated the same fairly and equitably among all customers of any class
generally affected thereby); PROVIDED that in the event that such additional
cost, reduction, payment, or foregone interest or Reimbursement Obligations or
other sum which was incurred by such Bank is subsequently returned or reimbursed
to such Bank, such Bank shall return or reimburse to the Borrower any additional
amount paid pursuant to this Section 3.8 by the Borrower to such Bank with
respect thereto. In the event that any of the foregoing events occur, each Bank
will use its reasonable efforts to take such actions as are reasonably feasible
and available to such Bank to decrease the additional costs payable hereunder;
PROVIDED that no Bank shall be required to transfer any activities related to
this Agreement to any jurisdiction in which such Bank does not at such time
regularly conduct ordinary banking operations or to a jurisdiction which
otherwise will be disadvantageous to such Bank. Such Bank shall give the
Borrower written notice of any event causing such additional cost, reduction,
payment or foregone interest or Reimbursement Obligation or other sum within 90
days of the occurrence thereof and the Borrower shall not be liable for any such
costs incurred prior to the date which is 90 days prior to the date of such
notice.

     Section 3.9. CERTIFICATE. A certificate setting forth any additional
amounts payable pursuant to Sections 3.7 and 3.8 and the changes as a result of
which such amounts are due and the computations in reasonable detail pursuant to
which such amounts were calculated, submitted by any Bank to the Borrower, shall
be conclusive absent manifest error. Upon delivery of a notice to such Bank no
more than thirty (30) Business Days after receipt of such certificate, the
Borrower shall have reasonable opportunity to review and discuss such
computations with a responsible officer at such Bank.

                                      -28-

     Section 3.10. CAPITAL ADEQUACY. If any present or future, or any change in
any present or future, law, governmental rule, regulation, policy, guideline or
directive (whether or not having the force of law) or the interpretation thereof
by a court or governmental authority with appropriate jurisdiction affects the
amount of capital required or expected to be maintained by any Bank or any
corporation controlling such Bank and such Bank determines that the amount of
capital required to be maintained by it or such corporation is increased by or
based upon the existence of its Commitment or the Loans made pursuant hereto,
then such Bank may notify the Borrower of such fact. To the extent that the
costs of such increased capital requirements are not reflected in the rates of
interest payable hereunder, the Borrower and such Bank shall thereafter attempt
to negotiate in good faith, within thirty (30) days of the day on which the
Borrower receives such notice, an adjustment payable hereunder that will
adequately compensate such Bank in light of these circumstances. If the Borrower
and such Bank are unable to agree to such adjustment within thirty (30) days of
the date on which the Borrower receives such notice, then commencing on the date
of such notice (but not earlier than the effective date of any such increased
capital requirement), the fees payable hereunder shall increase by an amount
that will, in such Bank's reasonable determination, provide adequate
compensation to such Bank, such amount to be conclusive and binding on the
Borrower, absent manifest error. Each Bank shall allocate such cost increases
among its customers in good faith and on an equitable basis.

     Section 3.11. INTEREST ON OVERDUE AMOUNTS. Overdue principal and (to the
extent permitted by applicable law) interest on the Loans and all other overdue
amounts payable hereunder or under any of the other Loan Documents shall bear
interest compounded daily and payable on demand at a rate per annum which is two
percent (2%) above the per annum interest rate otherwise applicable thereto,
until such amount shall be paid in full (after as well as before judgment).

     Section 3.12. PAYMENT DATE ADJUSTMENT FOR NON-BUSINESS DAYS. Unless
otherwise explicitly set forth herein, if any payment hereunder becomes due on a
day which is not a Business Day, the due date of such payment shall be extended
to the next succeeding Business Day, and such extension of time shall be
included in computing interest and fees in connection with such payment.

     Section 3.13. CURRENCY MATTERS. Dollars are the currency of account and
payment for each and every sum at any time due from the Borrower hereunder;
provided that:

     (a) except as expressly provided in this Credit Agreement, each repayment
of a Loan or a part thereof shall be made in the currency in which such Loan is
denominated at the time of that repayment;

     (b) each payment of interest shall be made in the currency in which such
principal or other sum in respect of which such interest is payable, is
denominated;

     (c) each payment of Letter of Credit Fees, the Facility Fees and the
Utilization Fees shall be in Dollars;

     (d) each payment in respect of costs, expenses and indemnities shall be
made in the currency in which the same were incurred; and

     (e) any amount expressed to be payable in Euros shall be paid in Euros.

<Page>

                                  -29-

     No payment to the Administrative Agent or any Bank (whether under any
judgment or court order or otherwise) shall discharge the obligation or
liability in respect of which it was made unless and until the Administrative
Agent or such Bank shall have received payment in full in the currency in which
such obligation or liability was incurred, and to the extent that the amount of
any such payment shall, on actual conversion into such currency, fall short of
such obligation or liability expressed in that currency, the Borrower shall
indemnify and hold harmless the Administrative Agent or such Bank, as the case
may be, with respect to the amount of the shortfall, with such indemnity
surviving the termination of this Credit Agreement and any legal proceeding,
judgment or court order pursuant to which the original payment was made which
resulted in the shortfall.

     Section 4. REPRESENTATIONS AND WARRANTIES. The Borrower represents and
warrants to the Banks and the Administrative Agent as follows:

     Section 4.1. CORPORATE AUTHORITY.

     (a) INCORPORATION; GOOD STANDING. Each of the Borrower and its Material
Subsidiaries (i) is a corporation duly organized, validly existing and in good
standing under the laws of its state of incorporation, (ii) has all requisite
corporate power and authority and legal right to own and operate its property,
to lease the property it operates as lessee and to conduct its business as now
conducted and as presently contemplated, and (iii) is in good standing as a
foreign corporation and is duly authorized to do business in each jurisdiction
where such qualification is necessary except where (x) a failure to be so
qualified would not have a materially adverse effect on the business, assets or
financial condition of the Borrower or the Borrower and its Material
Subsidiaries, taken as a whole or the Borrower's ability to perform the
Obligations or (y) the Borrower or such Subsidiary has applied for qualification
to do business in such jurisdiction and such application is pending.

     (b) AUTHORIZATION. The execution, delivery and performance of this Credit
Agreement and the other Loan Documents to which the Borrower is or is to become
a party and the transactions contemplated hereby and thereby (i) are within the
corporate authority and legal right of the Borrower, (ii) have been duly
authorized by all necessary corporate proceedings, (iii) do not conflict with or
result in any breach or contravention of any provision of law, statute, rule or
regulation to which the Borrower is subject or any judgment, order, writ,
injunction, license or permit applicable to the Borrower which would have a
materially adverse effect on the business, assets or financial condition of the
Borrower or the Borrower and its Material Subsidiaries, taken as a whole and
(iv) do not conflict with any provision of the corporate charter or bylaws of,
or any agreement or other instrument binding upon, the Borrower.

     (c) ENFORCEABILITY. The execution and delivery of this Credit Agreement and
the other Loan Documents to which the Borrower is or is to become a party will
result in valid and legally binding obligations of the Borrower enforceable
against it in accordance with the respective terms and provisions hereof and
thereof, except as enforceability is limited by bankruptcy, insolvency,
reorganization, moratorium or other laws relating to or affecting generally the
enforcement of creditors' rights and except to the extent that availability of
the remedy of specific performance or injunctive relief is subject to the
discretion of the court before which any proceeding therefor may be brought.

<Page>

                                       30

     Section 4.2. GOVERNMENTAL APPROVALS. The execution, delivery and
performance by the Borrower of this Credit Agreement and the other Loan
Documents to which the Borrower is or is to become a party and the transactions
contemplated hereby and thereby do not require the Borrower to obtain the
approval or consent of, to make a filing with, or to perform or obtain the
performance of any other act by or in respect of any governmental agency or
authority other than those already obtained or performed.

     Section 4.3. TITLE TO PROPERTIES; LEASES. Other than as noted on the
audited consolidated financial statements of the Borrower and its Subsidiaries
as at the Balance Sheet Date, the Borrower and its Subsidiaries own all of the
assets reflected in the consolidated balance sheet of the Borrower and its
Subsidiaries as at the Balance Sheet Date or acquired since that date (except
property and assets sold or otherwise disposed of in the ordinary course of
business since that date and except for defects of title to certain real
property which do not materially impair the value or usefulness thereof),
subject to no rights of others, including any mortgages, leases, conditional
sales agreements, title retention agreements, liens or other encumbrances,
except for liens permitted pursuant to Section 6.2. The Borrower and its
Material Subsidiaries enjoy peaceful and undisturbed possession under all leases
under which they are operating, and all said leases are valid and subsisting and
in full force and effect except to the extent that the failure to enjoy peaceful
and undisturbed possession of such lease or the failure of such lease to be
valid, subsisting and in full force and effect does not have a material adverse
effect on the assets, financial condition or business of the Borrower and its
Material Subsidiaries, taken as a whole.

     Section 4.4. FINANCIAL STATEMENTS. There has been furnished to each of the
Banks a consolidated balance sheet of the Borrower and its Subsidiaries as at
the Balance Sheet Date, and related consolidated statements of income, retained
earnings and cash flow for the fiscal year then ended, certified by Arthur
Andersen and Company, the Borrower's independent certified public accountants.
There has also been furnished to each of the Banks an unaudited consolidated
balance sheet of the Borrower and its Subsidiaries as at the end of fiscal
quarter ending September 30, 2001, and the related consolidated statement of
income and consolidated statement of cash flow for the portion of the Borrower's
fiscal year then elapsed, all in reasonable detail. Such balance sheets and
statements of income, retained earnings and cash flow have been prepared in
accordance with Generally Accepted Accounting Principles consistently applied
and are correct and complete and fairly present the financial condition of the
Borrower and its Material Subsidiaries as at the close of business on the date
thereof and the consolidated results of operations for the fiscal period then
ended. There are no contingent liabilities of the Borrower or any of its
Subsidiaries as of each such date involving material amounts, known to the
officers of the Borrower and not disclosed in said balance sheet and the related
notes thereto.

     Section 4.5. NO MATERIAL CHANGES, ETC. Since the Balance Sheet Date there
has occurred no Material Adverse Change.

     Section 4.6. FRANCHISES, PATENTS, COPYRIGHTS, ETC. Each of the Borrower and
its Subsidiaries, respectively, possesses or has a valid right to use all
material franchises, patents, copyrights, inventions, technology, trademark
registrations, trademarks, trade names, trade secrets, service marks, FCC
Licenses, other licenses and permits, and rights in respect of the foregoing
and, to the best of its knowledge, patent and trademark applications and rights
in respect thereto

                                      -31-

(collectively, the "PROPRIETARY RIGHTS"), adequate for the conduct of its
business substantially as now conducted without known conflict with any rights
of others which could affect or impair in a material manner the business or
assets of the Borrower and its Material Subsidiaries, taken as a whole. Except
as disclosed in the financial statements referred to in Section 4.4 hereof, the
Borrower is not aware of any existing or threatened infringement or
misappropriation of (a) any Proprietary Rights of others by the Borrower or any
of its Subsidiaries or (b) any Proprietary Rights of the Borrower or any of its
Subsidiaries by others, in any way which might materially adversely affect the
business, assets or condition, financial or otherwise, of the Borrower and its
Material Subsidiaries, taken as a whole.

     Section 4.7. NO LITIGATION. There are no actions, suits, proceedings or
investigations of any kind pending or, to the Borrower's knowledge, threatened
against the Borrower or any of its Subsidiaries before any court, tribunal or
administrative agency or board that, if adversely determined are reasonably
likely to in the aggregate, materially adversely affect the properties, assets,
financial condition or business of the Borrower and its Material Subsidiaries,
taken as a whole or materially impair the right of the Borrower and its Material
Subsidiaries, taken as a whole, to carry on business substantially as now
conducted by them, or result in any substantial liability not adequately covered
by insurance, or for which adequate reserves are not maintained on the
consolidated balance sheet of the Borrower, or which question the validity of
this Credit Agreement or any of the other Loan Documents, or any action taken or
to be taken pursuant hereto or thereto. There are no final judgments against the
Borrower or any of its Subsidiaries that, with other outstanding final
judgments, undischarged and not covered by insurance, exceeds in the aggregate
five percent (5%) of the Consolidated Net Worth of the Borrower.

     Section 4.8. NO MATERIALLY ADVERSE CONTRACTS, ETC. Neither the Borrower nor
any of its Subsidiaries is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation that has or, to
the Borrower's knowledge, is expected in the future to have a materially adverse
effect on the business, assets or financial condition of the Borrower and its
Material Subsidiaries, taken as a whole. Neither the Borrower nor any of its
Subsidiaries is a party to any contract or agreement that has or, to the best of
the Borrower's knowledge, is expected, in the judgment of the Borrower's
officers, to have any materially adverse effect on the business of the Borrower
and its Material Subsidiaries, taken as a whole.

     Section 4.9. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. Neither the
Borrower nor any of its Subsidiaries is in violation of any provision of its
charter documents, bylaws, or any agreement or instrument to which it is subject
or by which it or any of its properties are bound or any decree, order,
judgment, statute, license, rule or regulation, in any of the foregoing cases in
a manner that are reasonably likely to result in the imposition of substantial
penalties or materially and adversely affect the financial condition, properties
or business of the Borrower and its Material Subsidiaries, taken as a whole or
the Borrower's ability to perform the Obligations.

     Section 4.10. TAX STATUS. The Borrower and, to the best of the Borrower's
knowledge, its Subsidiaries have (a) made or filed all federal and state income
and all other material tax returns, reports and declarations required by any
jurisdiction to which any of them is subject or properly filed for and received
extensions with respect thereto which are still in full force and effect and
which have been fully complied with in all material respects, (b) paid all taxes

such returns, reports

                                      -32-

and declarations, except those being contested in good faith by appropriate
proceedings and for which adequate reserves, to the extent required by Generally
Accepted Accounting Principles, have been established and (c) set aside on their
books provisions reasonably adequate for the payment of all estimated taxes for
periods subsequent to the periods to which such returns, reports or declarations
apply. There are no unpaid taxes in any material amount claimed to be due by the
taxing authority of any jurisdiction, and the officers of the Borrower know of
no basis for any such claim.

     Section 4.11. NO EVENT OF DEFAULT. No Default or Event of Default has
occurred and is continuing.

     Section 4.12. HOLDING COMPANY AND INVESTMENT COMPANY ACTS. Neither the
Borrower nor any of its Subsidiaries is a "HOLDING COMPANY", or a "SUBSIDIARY
COMPANY" of a "HOLDING COMPANY", or an "AFFILIATE" of a "HOLDING COMPANY", as
such terms are defined in the Public Utility Holding Company Act of 1935; nor is
it a "REGISTERED INVESTMENT COMPANY", or an "AFFILIATED COMPANY" or a "PRINCIPAL
UNDERWRITER" of a "REGISTERED INVESTMENT COMPANY", as such terms are defined in
the Investment Company Act of 1940.

     Section 4.13. CERTAIN TRANSACTIONS. Except for arm's length transactions
pursuant to which the Borrower makes payments in the ordinary course of business
upon terms no less favorable than the Borrower could obtain from third parties
and transactions disclosed in the Borrower's Form 10-K filed with the Securities
and Exchange Commission for its fiscal year ending December 31, 2000, none of
the officers, directors or other key employees of the Borrower or any of its
Material Subsidiaries is presently a party to any transaction with the Borrower
or any of its Material Subsidiaries (other than for services as employees,
officers and directors), including any contract, agreement or other arrangement
providing for the furnishing of services to or by, providing for rental of real
or personal property to or from, or otherwise requiring payments to or from any
officer, director or such key employee or, to the knowledge of the Borrower, any
corporation, partnership, trust or other entity in which any officer, director,
or any such key employee has a substantial interest or is an officer, director,
trustee or partner.

     Section 4.14. ERISA COMPLIANCE.

     (a) IN GENERAL. To the best of the Borrower's knowledge, the Borrower and
its Subsidiaries have complied in all material respects with provisions of the
Code, to the extent applicable, and of ERISA relevant to the Borrower's Pension
Plans (as defined in Section 3(2) of ERISA), including the provisions thereof
respecting funding requirements for, and the termination of, such plans and
respecting prohibited transactions thereunder, and the funding of any Guaranteed
Pension Plan complies with the minimum funding standards of Section 412 of the
Code.

     (b) GUARANTEED PENSION PLANS. Each contribution required to be made to a
Guaranteed Pension Plan, whether required to be made to avoid the incurrence of
an accumulated funding deficiency, the notice or lien provisions of Section
302(f) of ERISA, or otherwise, has been timely made. No waiver of an accumulated
funding deficiency or extension of amortization periods has been received with
respect to any Guaranteed Pension Plan. No liability to the PBGC (other than
required insurance premiums, all of which have been paid) has

<Page>

                                      -33-

been incurred by the Borrowers or any ERISA Affiliate with respect to any
Guaranteed Pension Plan and there has not been any ERISA Reportable Event, or
any other event or condition which presents a material risk of termination of
any Guaranteed Pension Plan by the PBGC. Based on the latest valuation of each
Guaranteed Pension Plan (which in each case occurred within twelve months of the
date of this representation), and except as disclosed on SCHEDULE 4.14 attached
hereto, the current value of all accrued benefits under each of such plans did
not, as of the latest valuation date, exceed the then current value of the
assets of such plans allocable to such accrued benefits based upon the actuarial
methods and assumptions used for such plans.

     (c) MULTIEMPLOYER PLANS. Neither the Borrower nor any ERISA Affiliate has
incurred any material liability (including secondary liability) to any
Multiemployer Plan as a result of a complete or partial withdrawal from such
Multiemployer Plan under Section 4201 of ERISA or as a result of a sale of
assets described in Section 4204 of ERISA. Neither the Borrower nor any ERISA
Affiliate has been notified that any Multiemployer Plan is in reorganization or
insolvent under and within the meaning of Section 4241 or Section 4245 of ERISA
or that any Multiemployer Plan intends to terminate or has been terminated under
Section 4041A of ERISA.

     Section 4.15. PURPOSE CREDIT.

     (a) The Borrower has not engaged principally or as one of its important

System.

     (b) The Borrower shall not, directly or indirectly, apply any part of the
proceeds of the Notes for the purpose of or in connection with the Borrower's
broker-dealer activities, if any, within the meaning of Regulation T of the
Federal Reserve Board (Title 12, Part 220, Code of Federal Regulations, as
amended) or any published regulations, interpretations or rulings thereunder.

     (c) The issuance of the Notes and the application of the proceeds thereof
by the Borrower will not contravene Regulation X of the Federal Reserve Board
(Title 12, Part 224, Code of Federal Regulations, as amended) or any published
regulations, interpretations or rulings thereunder.

     Section 4.16. ENVIRONMENTAL COMPLIANCE.

     (a) The Borrower has no actual knowledge that any operator of the Real
Estate, has violated, or is alleged to have violated, any judgment, decree,
order, law, license, rule or regulation pertaining to environmental matters
(hereinafter "ENVIRONMENTAL LAWS"), which violation would have a material
adverse effect on the environment or the business, assets or financial condition
of the Borrower or any of its Material Subsidiaries, taken as a whole.

     (b) Neither the Borrower nor any of its Material Subsidiaries has received
notice from any third party including, without limitation, any federal, state or
local governmental authority, (i) that any one of them has been identified by
the United States Environmental Protection Agency ("EPA") as a potentially
responsible party under the Comprehensive Environmental Response, Compensation
and Liability Act of 1980 with respect to a site listed on the National

disposed of has been found at any site at which a federal, state or local agency
or other third party has conducted or has ordered that the Borrower or any of
its Material Subsidiaries conduct a remedial investigation, removal or other
response action pursuant to any Environmental Law; or (iii) that it is or shall
be a named party to any claim, action, cause of action, complaint, or legal or
administrative proceeding (in each case, contingent or otherwise) arising out of
any third party's incurrence of costs, expenses, losses or damages of any kind
whatsoever in connection with the release of Hazardous Substances.

     (c) Neither the Borrower nor any of its Material Subsidiaries are subject
to any applicable environmental law requiring the performance of Hazardous
Substances site assessments, or the removal or remediation of Hazardous
Substances, or the giving of notice to any governmental agency or the recording
or delivery to other Persons of an environmental disclosure document or

compliance with all applicable provisions of the Fair Labor Standards Act of
1938 (29 U.S.C. Sections 106 And 207) except to the extent that the Borrower's
failure to comply therewith would not have a material adverse affect on the
business, assets or condition, financial or otherwise, of the Borrower and its
Material Subsidiaries, taken as a whole. To the best of the Borrower's
knowledge, none of the Borrower's inventory has been produced by employees who
are or were employed in violation of the minimum wage or maximum hour provisions
of such Act or any regulations thereunder.

will do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate existence, material rights, franchises and

Subsidiaries if such discontinuance is, in the sole judgment of the Borrower,
desirable in the conduct of its or their business and that do not in the
aggregate materially adversely affect the business of the Borrower and its
Material Subsidiaries on a consolidated basis.

     Section 5.6. INSURANCE. The Borrower will, and will cause each of its
Subsidiaries to, maintain with financially sound and reputable insurers

areas and in amounts, containing such terms, in such forms and for such periods
as may be reasonably satisfactory to the Administrative Agent; PROVIDED,
HOWEVER, that the Borrower and any Subsidiary may self-insure for physical
damage to automobiles, welfare benefits and against liability to workers in any
state or jurisdiction, or may effect worker's compensation insurance therein
through an insurance fund operated by such state or jurisdiction; and PROVIDED,
FURTHER, that notwithstanding anything to the contrary contained herein, the

Borrower nor any of its Subsidiaries conducts a material portion of its
business, that in the aggregate are not material to the business or assets of
the Borrower on an individual basis or of the Borrower and its Subsidiaries on a
consolidated basis) imposed upon it and its real properties, sales and
activities, or any part thereof, or upon the income or profits therefrom, as
well as all claims for labor, materials, or supplies that if unpaid might by law
become a lien or charge upon any of its property; PROVIDED that any such tax,
assessment, charge, levy or claim need not be paid if the validity or amount
thereof shall currently be contested in good faith by appropriate proceedings
and if the Borrower or such Subsidiary shall have set aside on its books
adequate reserves with respect thereto; and PROVIDED FURTHER that the Borrower
and each Subsidiary of the Borrower will pay all such taxes, assessments,
charges, levies or claims forthwith upon the commencement of proceedings to
foreclose any lien that may have attached as security therefor.

     Section 5.8. INSPECTION OF PROPERTIES AND BOOKS. The Borrower shall permit
the Banks, through the Administrative Agent or any of the Banks' other

Borrower or any of its Subsidiaries, to examine the books of

<Page>

                                      -38-

account of the Borrower and its Subsidiaries (and to make copies thereof and
extracts therefrom), and to discuss the affairs, finances and accounts of the
Borrower and its Subsidiaries with, and to be advised as to the same by, its and
their officers, employees and independent public accountants (such accountants
being hereby authorized by the Borrower to so discuss and advise) all at such
reasonable times and intervals as the Administrative Agent or any Bank may
reasonably request. In connection with any such inspections or discussions, each
Bank, on behalf of itself and any representative authorized by it, agrees to
treat all non-public information as confidential information pursuant to Section
25 and to take all reasonable precautions to prevent such confidential
information from being exposed to third parties and to those of its employees
and representatives who do not need to know such confidential information;
PROVIDED that this Section 5.8 shall not affect the disclosure by any Bank of
information required to be disclosed to its auditors, regulatory agencies or

instruments by which it or any of its properties or business may be bound and
(d) all applicable decrees, orders, and judgments; if in each such case failure
to comply would have a materially adverse effect on the Borrower and its
Material Subsidiaries, taken as a whole. If at any time any authorization,
consent, approval, permit or license from any officer, agency or instrumentality
of any government shall become necessary or required in order that the Borrower
may fulfill any of the Obligations, the Borrower will promptly take or cause to
be taken all reasonable steps within the power of the Borrower to obtain such
authorization, consent, approval, permit or license and furnish the Banks with
evidence thereof.

     Section 5.10. PENSION PLANS. The Borrower and any ERISA Affiliate shall:

indenture or other obligation to which or with respect to which the Borrower or
any of its Subsidiaries is a party or obligor, whether as principal or surety,

forthwith terminate and each of the Banks shall be relieved of all obligations
to make Loans hereunder and the Administrative Agent shall be relieved of all
further obligations to issue, extend or renew Letters of Credit. If any other
Event of Default shall have occurred and be continuing, the Administrative
Agent, upon the request of the Majority Banks, shall, by notice to the Borrower,
terminate the unused portion of the credit hereunder, and upon such notice being
given such unused portion of the credit hereunder shall terminate immediately
and each of the Banks shall be relieved of all further obligations to make Loans
and the Administrative Agent shall be relieved of all further obligations to
issue, extend or renew Letters of Credit. If any such notice is given to the
Borrower, the Administrative Agent will forthwith furnish a copy thereof to each
of the Banks. No termination of the credit hereunder shall relieve the Borrower
of any of the Obligations or any of its existing obligations to the Banks
arising under other agreements or instruments.

     Section 11. THE AGENTS.

     Section 11.1. AUTHORIZATION. The Administrative Agent is authorized to take
such action on behalf of each of the Banks and to exercise all such powers as
are hereunder and in related documents delegated to the Administrative Agent,
together with such powers as are reasonably incident thereto; PROVIDED that no
duties or responsibilities not expressly assumed herein or therein shall be
implied to have been assumed by the Administrative Agent. The relationship among
the Agents, on the one hand, and the Banks, on the other hand, shall be that of
agent and principal only and nothing contained in this Credit Agreement or any
of the related documents shall be construed to constitute the Agents as trustees
of the Banks.

     Section 11.2. EMPLOYEES AND AGENTS. The Administrative Agent may exercise
its powers and execute its duties by or through employees or agents and shall be
entitled to take, and to rely on, advice of counsel concerning all matters
pertaining to its rights and duties under this Credit Agreement and the other
Loan Documents. The Administrative Agent may utilize the services of such
Persons as the Administrative Agent in its sole discretion may reasonably
determine, and upon the occurrence and during the continuation of a Default or
an Event of Default, all reasonable fees and expenses of any such Persons shall
be paid by the Borrower.

     Section 11.3. NO LIABILITY. None of the Agents nor any of their respective
shareholders, directors, officers or employees nor any other Person assisting
them in their duties nor any agent or employee thereof, shall be liable for any
waiver, consent or approval given or any action taken, or omitted to be taken,
in good faith by it or them hereunder or under any of the other Loan Documents,
or in connection herewith or therewith, or be responsible for the consequences
of any oversight or error of judgment whatsoever, except that the Agents or such
other Person, as the case may be, may be liable for losses due to its own
willful misconduct or gross negligence.

     Section 11.4. NO REPRESENTATIONS. The Agents shall not be responsible for
the execution or validity or enforceability of this Credit Agreement, the Notes,
the Letters of Credit or any instrument at any time constituting, or intended to
constitute, collateral security for the Notes, or for the value of any such
collateral security or for the validity, enforceability or collectability of any
such amounts owing with respect to the Notes, or for any recitals or statements,
warranties or representations made herein or in any of the other Loan Documents
or in any certificate or instrument hereafter furnished to it by or on behalf of
the Borrower, or be bound to ascertain or inquire as to the performance or
observance of any of the terms, conditions, covenants or agreements herein or in
any instrument at any time constituting, or intended to constitute, collateral
security for the Notes. The Agents shall not be bound to ascertain whether any
notice, consent, waiver or request delivered to them by the Borrower or any
holder of any of the Notes shall have been duly authorized or is true, accurate
and complete. The Agents have not made nor do they now make any representations
or warranties, express or implied, nor do they assume any liability to the
Banks, with respect to the credit worthiness or financial conditions of the
Borrower or any of its Subsidiaries. Each Bank acknowledges that it has,
independently and without reliance upon the Agents or the other Banks, and based
upon such information and documents as it has deemed appropriate, made its own
credit analysis and decision to enter into this Credit Agreement.

     Section 11.5. PAYMENTS. If in the opinion of the Administrative Agent the
distribution of any amount received by it in such capacity hereunder or under
the Notes might involve it in liability, it may refrain from making distribution
until its right to make distribution shall have been adjudicated by a court of
competent jurisdiction. If a court of competent jurisdiction shall adjudge that
any amount received and distributed by the Administrative Agent is to be repaid,
each Person to whom any such distribution shall have been made shall either
repay to the Administrative Agent its proportionate share of the amount so
adjudged to be repaid or shall pay over the same in such manner and to such
Persons as shall be determined by such court. With respect to Obligations, a
payment to the Administrative Agent shall be deemed to be a payment to each Bank
of its PRO RATA share of such payment.

     Section 11.6. HOLDERS OF NOTES. The Administrative Agent may deem and treat
the payee of any Note or the purchaser of any Letter of Credit Participation as
the absolute owner thereof for all purposes hereof until it shall have been
furnished in writing with a different name by such payee or by a subsequent
holder.

     Section 11.7. INDEMNITY. The Banks jointly and severally agree hereby to
indemnify and hold harmless the Agents from and against any and all claims,
actions and suits (whether groundless or otherwise), losses, damages, costs,
expenses (including any expenses for which the Agents have not been reimbursed
by the Borrower as required by Section 12 or Section 13), and liabilities of
every

<Page>

                                      -52-

nature and character arising out of or related to this Credit Agreement or the
Notes or the transactions contemplated or evidenced hereby or thereby, or the
Agents' actions taken hereunder or thereunder, except to the extent that any of
the same shall be directly caused by such Agent's own willful misconduct or
gross negligence.

     Section 11.8. AGENTS AS BANKS. In their individual capacities, Fleet,
LaSalle Bank National Association, Wachovia Bank, N.A., The Bank of
Tokyo-Mitsubishi, Ltd., Chicago Branch, and Toronto Dominion (Texas), Inc. shall
have the same obligations and the same rights, powers and privileges in respect
to its Commitments and the Loans made by it, and as the holder of any of the
Notes and as the purchaser of any Letter of Credit Participations, as Fleet
would have were it not also an Agent or an Affiliate of an Agent.

     Section 11.9. RESIGNATION. Any Agent may resign at any time by giving
ninety (90) days' prior written notice thereof to the Banks and the Borrower.
Upon any such resignation, the Majority Banks shall have the right to appoint
another Bank or any other financial institution as the successor Agent. Unless a
Default or Event of Default shall have occurred and be continuing, such
successor, if other than a Bank, shall be reasonably acceptable to the Borrower.
If no successor Agent shall have been so appointed by the Majority Banks and
shall have accepted such appointment within thirty (30) days after the retiring
Agent's giving of notice of resignation, then the retiring Agent may, on behalf
of the Banks, appoint a successor Agent, as the case may be. Upon the acceptance
of any appointment as Agent hereunder by a successor Agent, such successor Agent
shall thereupon 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. After any retiring Agent's
resignation, the provisions of this Credit Agreement shall continue in effect
for its benefit in respect of any actions taken or omitted to be taken by it
while it was acting as Agent.

     Section 11.10. DOCUMENTATION AGENTS AND SYNDICATION AGENT. Neither the
Documentation Agents nor the Syndication Agent shall have any right, power,
obligation, liability, responsibility or duty under this Credit Agreement other
than those applicable to all Banks as such.

     Section 12. EXPENSES. The Borrower agrees to pay (a) the reasonable cost of
producing and reproducing this Credit Agreement, the other Loan Documents and
the other agreements and instruments mentioned herein, (b) any taxes (including
any interest and penalties in respect thereto) payable by the Administrative
Agent or the Banks (other than taxes based upon the Administrative Agent's or
any Bank's net income) on or with respect to the transactions contemplated by
this Credit Agreement (the Borrower hereby agreeing to indemnify the Banks with
respect thereto), (c) the reasonable fees, expenses and disbursements of the
Administrative Agent's Special Counsel or any local counsel to the
Administrative Agent incurred in connection with the preparation, syndication,
administration or interpretation of the Loan Documents and other instruments
mentioned herein, each closing hereunder, and amendments, modifications,
approvals, consents or waivers hereto or hereunder regardless of whether any
such transaction is consummated, (d) the fees, expenses and disbursements of the
Administrative Agent incurred by the Administrative Agent in connection with the
preparation, syndication, administration or interpretation of the Loan Documents
and other instruments mentioned herein, each closing hereunder and amendments,
modifications, approvals, consents or waivers hereto or hereunder, regardless of
whether any such transaction is consummated, and (e) all reasonable
out-of-pocket

<Page>

                                      -53-

expenses (including reasonable attorneys' (which attorneys may be, but shall not
be required to be, employees of any Bank or the Administrative Agent) fees and
costs) incurred by any Bank or the Administrative Agent in connection with (i)
the enforcement of any of the Loan Documents against the Borrower or any of its
Subsidiaries or the administration thereof after the occurrence of a Default or
Event of Default, (ii) any so-called "WORK-OUT" of the Obligations and (iii) any
litigation, proceeding or dispute whether arising hereunder or otherwise in
connection with the transactions contemplated hereby or under the other Loan
Documents, in any way related to any Bank's or the Administrative Agent's
relationship with the Borrower or any of its Subsidiaries. The covenants of this
Section 12 shall survive payment or satisfaction of payment of amounts owing
under or with respect to the Loan Documents.

     Section 13. INDEMNIFICATION. The Borrower agrees to indemnify and hold
harmless the Administrative Agent and the Banks from and against any and all
claims, actions and suits whether groundless or otherwise, and from and against
any and all liabilities, losses, damages and expenses of every nature and
character arising out of this Credit Agreement or any of the other Loan
Documents or the transactions evidenced hereby unless any such claims, actions
or suits arise out of the Administrative Agent's or the Banks' intentional
misconduct or gross negligence. In litigation, or the preparation therefor, the
Banks and the Administrative Agent shall be entitled to select their own counsel
and, in addition to the foregoing indemnity, the Borrower agrees to pay promptly
the reasonable fees and expenses of such counsel. If, and to the extent that the
obligations of the Borrower under this Section 13 are unenforceable for any
reason, the Borrower hereby agrees to make the maximum contribution to the
payment in satisfaction of such obligations which is permissible under
applicable law. The covenants of this Section 13 shall survive payment or
satisfaction of payment of amounts owing under or with respect to the Loan
Documents.

     Section 14. SURVIVAL OF COVENANTS, ETC. All covenants, agreements,
representations and warranties made herein, in the Notes, in any of the other
Loan Documents or in any documents or other papers delivered by or on behalf of
the Borrower pursuant hereto shall be deemed to have been relied upon by the
Banks and the Administrative Agent, notwithstanding any investigation heretofore
or hereafter made by any of them, and shall survive the making by the Banks of
the Loans and the issuance, extension or renewal of any Letters of Credit, as
herein contemplated, and shall continue in full force and effect so long as any
Obligation remains outstanding or any Bank has any obligation to make any Loans
or the Administrative Agent has any obligation to issue, extend or renew any
Letter of Credit. All statements contained in any certificate or other paper
delivered to any Bank or the Administrative Agent at any time by or on behalf of
the Borrower pursuant hereto or in connection with the transactions contemplated
hereby shall constitute representations and warranties by the Borrower
hereunder.

     Section 15. ASSIGNMENT AND PARTICIPATION. Section 15.1. CONDITIONS TO
ASSIGNMENT BY BANKS. Except as provided herein, each Bank may assign to one or
more Eligible Assignees all or a portion of its interests, rights and

assignee Bank is an Affiliate of the Borrower, then any such assignee Bank shall
have no right to vote as a Bank hereunder or under any of the other Loan
Documents for purposes of granting consents or waivers or for purposes of
agreeing to amendments or other modifications to any of the Loan Documents or
for purposes of making requests to the Administrative Agent pursuant to Section
10, and the determination of the Majority Banks shall for all purposes of this
Agreement and the other Loan Documents be made without regard to such assignee
Bank's interest in any of the Loans or Reimbursement Obligations. If any Bank
sells a participating interest in any of the Loans or Reimbursement Obligations
to a participant, and such participant is the Borrower or an Affiliate of the
Borrower, then such transferor Bank shall promptly notify the Administrative
Agent of the sale of such participation. A transferor Bank shall have no right

purposes of granting consents or waivers or for purposes of agreeing to
amendments or modifications to any of the Loan Documents or for purposes of
making requests to the Administrative Agent pursuant to Section 10 to the extent

Obligations to the extent of such participation.

     Section 15.8. MISCELLANEOUS ASSIGNMENT PROVISIONS. Any assigning Bank shall
retain its rights to be indemnified pursuant to Section 12 and Section 13 with

any interest or fees are payable hereunder or under any of the other Loan
Documents for its account, deliver to the Borrower and the Administrative Agent
two duly completed copies of United States Internal Revenue Service Form W-8BEN

case that such Bank is entitled to receive payments under this Credit Agreement
or any of the other Loan Documents payable to it, without deduction or
withholding of any United States federal income taxes. Anything contained in
this Section 15 to the contrary notwithstanding, any Bank may at any time pledge
all or any portion of its interest and rights under this Credit Agreement
(including all or any portion of its Notes) to any of the twelve Federal Reserve
Banks organized under Section 4 of the Federal Reserve Act, 12 U.S.C. Section
341. No such pledge or the enforcement thereof shall release the pledgor Bank
from its obligations hereunder or under any of the other Loan Documents.

impair any right consequent thereon. No course of dealing or delay or omission
on the part of any Bank or the Administrative Agent in exercising any right
shall operate as a waiver thereof or otherwise be prejudicial thereto. No notice
to or demand upon the Borrower shall entitle the Borrower to other or further
notice or demand in similar or other circumstances.

     Section 23. FCC APPROVAL. Notwithstanding anything to the contrary
contained in this Credit Agreement or in the other Loan Documents, neither the
Administrative Agent nor any Bank will take any action pursuant to this
Agreement or any of the other Loan Documents, which would constitute or result
in a change in control of the Borrower or any of its Subsidiaries requiring the
prior approval of the FCC without first obtaining such prior approval of the
FCC. After the occurrence of an Event of Default, the Borrower shall take or
cause to be taken any action which the Agents may reasonably request in order to
obtain from the FCC such approval as may be necessary to enable the Agents to
exercise and enjoy the full rights and benefits granted to the Administrative
Agent, for the benefit of the Banks by this Credit Agreement or any of the other
Loan Documents, including, at the Borrower's cost and expense, the use of the
Borrower's best efforts to assist in obtaining such approval for any action or
transaction contemplated by this Credit Agreement or any of the other Loan
Documents for which such approval is required by law.

     Section 24. SEVERABILITY. The provisions of this Credit Agreement are
severable and if any one clause or provision hereof shall be held invalid or
unenforceable in whole or in part in any jurisdiction, then such invalidity or
unenforceability shall affect only such clause or provision, or part thereof, in
such jurisdiction, and shall not in any manner affect such clause or provision
in any other jurisdiction, or any other clause or provision of this Credit
Agreement in any jurisdiction.

     Section 25. CONFIDENTIALITY. Each of the Banks and the Administrative Agent
agrees to keep any non-public information delivered or made available to it
pursuant to this Credit Agreement or any other Loan Document confidential from
any Person other than officers, employees, agents, accountants, professional
advisors, counsel, designees or representatives of such Bank or the
Administrative Agent who are or are expected to become engaged in evaluating,
approving, structuring or administering this Credit Agreement or any of the
other Loan Documents; PROVIDED, THAT, nothing herein shall prevent the
Administrative Agent or any Bank from disclosing such information (i) to any
assignee or participant that has agreed in writing to comply with the
confidentiality provision of this Section 25 in connection with the contemplated
assignment or participation, (ii) to any of its Affiliates to the extent any
such Affiliates require such information in the ordinary course of the
Administrative Agent's or such

non-exclusive, perpetual license in such intellectual property to Cygnus, however Sankyo shall bear the cost and responsibility of filing, prosecuting and maintaining such intellectual
property rights. 

        9.5    Claim of Infringement.    If Sankyo or Cygnus ("Receiving Party") receives a claim that any of the Product
infringe upon a patent or copyright, or that any Cygnus Trademarks employed with a Product infringe upon a registered trademark, service mark, logo or protectable trade-dress of a third party in the
U.S., the Receiving Party will notify the other party promptly in writing to ensure that Cygnus has all necessary information and assistance and the authority to evaluate and defend such claim.
Cygnus, at its sole and absolute discretion, shall determine what course of action it wishes to take in defending such a claim including but not limited to litigation, license and the like. Cygnus
warrants and represents that it shall use its commercially reasonable efforts to secure a right to continue using the Product free of liability for infringement of any third party patent, copyright,
trademark or any other intellectual property right. Royalties and other payments associated with such right shall be borne by Cygnus. Cygnus shall indemnify, defend and hold harmless Sankyo, and its
officers, directors, employees and agents with respect to such claims in accordance with the terms and conditions of Article 12. 

        9.6    Infringement by Third Parties.    Each party shall notify the other party in writing promptly upon its becoming
aware of any infringement by a third party of Cygnus Intellectual Property Rights 

13

 

utilized in manufacturing, using, developing, supplying, importing, exporting, marketing, distributing, co-promoting, offering for sale or selling the Product. Cygnus shall have the
right, but not the
obligation, to file and maintain lawsuits in its own name for infringement by third parties of any Cygnus Intellectual Property Rights related to any Product. Sankyo shall cooperate as reasonably
requested by Cygnus, at Cygnus' expense, in any investigation or action taken by Cygnus in respect of such infringement. All sums obtained as a result of such suit or proceeding, whether by judgment,
award, decree or settlement, shall be the property of Cygnus except, however, Cygnus shall pay to Sankyo [CONFIDENTIAL TREATMENT REQUESTED BY CYGNUS, INC.] of all sums
obtained after such sums are first applied to reimburse Cygnus for its out-of-pocket costs incurred in connection therewith. In the event that Cygnus chooses not to pursue
legal action against such infringing third party and the infringing product or products subsequently obtains at least [CONFIDENTIAL TREATMENT REQUESTED BY CYGNUS, INC.]
of the market share for the Product, wherein the market is defined as the Cygnus Product and the infringing reverse iontophoresis glucose monitoring product or products, then Cygnus shall treat the
volume of the infringing reverse iontophoresis glucose monitoring product or products as Net Sales during the period of infringement. In the case there is a dispute between the parties as to whether a
third party infringes Cygnus Intellectual Property Rights, the parties shall request the opinion of a mutually agreed upon third party patent expert and shall equally bear the cost of such expert. 

        9.7    No Other Licenses.    Cygnus agrees it will not assert against Sankyo any claim of infringement under Cygnus
Patent Rights based on Sankyo's activities under this Agreement during the Term. No other rights or licenses, whether express or implied, in Cygnus' intellectual property are granted by Cygnus to
Sankyo. 

10.  CONFIDENTIALITY  

        10.1    Confidentiality.    Each party agrees that any Proprietary Information it obtains from the other party is the
confidential property of the disclosing party, and may not be used by the receiving party other than in connection with the activities contemplated under this Agreement. Except as expressly permitted
in this Agreement, the receiving party will hold in confidence and not use or disclose any Proprietary Information of the disclosing party and shall obtain the prior written permission of the other
party before releasing such Proprietary Information to a third party. If such permission is granted, the releasing party shall ensure that the third party is bound to the same obligations of
confidentiality. The restrictions on use and disclosure of Proprietary Information imposed upon a receiving party under this Section 10.1 shall continue in full force and effect during the Term
and for a period of five (5) years thereafter.

of this Agreement, redacted to the extent permissible, with the U.S. Securities and Exchange Commission. Both parties will consult with each other prior to issuing any future press release relating to
this Agreement. 

        14.10    Force Majeure.    No liability or loss of rights hereunder shall result to either party from delay or failure
in performance (other than payment of money) caused by governmental actions or restrictions (provided that any such governmental action or restriction was not the result of actions of a party to this
Agreement), war, terrorist activities, civil commotion, riots, strikes, power outages, lock outs and acts of God such as fire, flood, earthquakes, lightning, drought or other similar or dissimilar
causes that are beyond the control of the parties (each, a "Force Majeure Act").

        14.11    Remedies.    Except as otherwise expressly stated in this Agreement including but not limited to Sections
11.2, 11.3, 11.4 and 11.5, the rights and remedies of a party set forth herein with respect to failure of the other to comply with the terms and conditions of this Agreement (including, without
limitation, rights of full termination of this Agreement) are not exclusive, the exercise thereof shall not constitute an election of remedies, and the aggrieved party shall in all events be entitled
to seek whatever additional remedies may be available in law or in equity. 

        14.12    Nonemployment.    During the Term and for a period [CONFIDENTIAL TREATMENT REQUESTED BY
CYGNUS, INC.] thereafter, neither party will employ any current employee of the other party unless agreed to in writing by the parties. 

        14.13    Counterparts.    This Agreement may be executed in two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument. 

        14.14    Interpretation.    The parties agree that the rule of construction to the effect that any ambiguities are
resolved against the drafting party shall not be employed in the interpretation of this Agreement and that the terms and conditions of this Agreement shall be construed fairly with respect to the
parties hereto and shall not be construed in favor or against any one party, regardless of which party was generally responsible for the preparation of this Agreement. 

IN WITNESS WHEREOF, the undersigned have caused this Agreement to be executed by their duly authorized officers as of the date first written above.
