THE CREDITS

2.1 Commitments

2.1.1 Loan Commitment. From and including the Effective Date and prior to the
Facility Termination Date, each Lender severally agrees, on the terms and conditions set
forth in this Agreement, to (i) make Loans to the Borrower and (ii) participate in Facility
LCs issued upon the request of the Borrower, provided that, after giving effect to the
making of each such Loan and the issuance of each such Facility LC, (A) such Lender’s
Outstanding Credit Exposure shall not exceed its Commitment; (B) the sum of the aggregate
outstanding principal amount of the Revolving Credit Loans plus the Financial LC
Obligations shall not exceed the Aggregate Revolving Credit and Financial LC Commitment at
any time, (C) the total Revolving Credit Loans outstanding shall not exceed the Aggregate
Revolving Credit Commitment; (D) the Aggregate Outstanding Credit Exposure shall not exceed
the Aggregate Commitment at any time during any Unrestricted Period; and (E) the Aggregate
Outstanding Credit Exposure shall not exceed the lesser of (1) the Aggregate Commitment and
(2) the Borrowing Base at any time during any Restricted Period (subject to Section
2.2(c)). Subject to the terms of this Agreement, the Borrower may borrow, repay and
reborrow at any time prior to the Business Day prior to the Facility Termination Date. All
Commitments shall expire on the Facility Termination Date. An Issuer will issue Facility
LCs hereunder on the terms and conditions set forth in Section 2.19.

2.1.2 Swing Line Commitment

(a) Subject to the terms and conditions hereof, the Swing Line Lender agrees at
any time and from time to time on and after the Effective Date and prior to the
Facility Termination Date, to make Swing Line loans (each, a “Swing Line
Loan” and collectively, the “Swing Line Loans”) to the Borrower in an
aggregate principal amount at any one time outstanding not to exceed $25,000,000,
which Swing Line Loans (i) shall be made and maintained pursuant to one or more
Advances comprised of Floating Rate Advances and which shall not be entitled to be
converted into Eurodollar Advances, (ii) shall be made in the minimum amount of
$1,000,000 (or if less, in the aggregate amount of the remaining unused portion of
the Aggregate Revolving Credit Commitment), and (iii) may be repaid and, so long as
no Default or Unmatured Default exists hereunder, reborrowed, at the option of the
Borrower, in accordance with the provisions hereof. Swing Line Loans shall
constitute “Loans” for all purposes hereunder, except they shall be held by
the Swing Line Lender (subject to Section 2.1.2(b) below) and, only for
purposes of calculating the commitment fee under Section 2.5, shall not be
considered a utilization of the Commitment of any Lender hereunder. Notwithstanding
the foregoing, the Aggregate Outstanding Credit Exposure shall not exceed the
Aggregate Commitment at any time during any Unrestricted Period and the Aggregate
Outstanding Credit Exposure shall not exceed the lesser of (A) the Aggregate
Commitment and (B) the Borrowing Base at any time during a Restricted Period
(subject to Section 2.2(c)).

(b) If any Swing Line Loan is not repaid when due, the Swing Line Lender shall
give notice to the Agent to request each Lender, including the Swing Line Lender, to
make a Loan as a Floating Rate Advance in an amount equal to the product of such
Lender’s Pro Rata Share times the outstanding principal balance of such Swing Line
Loan (the “Refunded Swing Line Loan”) outstanding on the date such notice is
given; provided that the provision of this subsection shall not affect the
obligation of the Borrower to prepay Swing Line Loans in accordance with Section
2.2. Each Lender shall make the proceeds of such Loan available to the Agent
for the account of the Swing Line Lender on the next Business Day following such
request, in immediately available funds. The proceeds of such Loans shall be
immediately applied to repay the Refunded Swing Line Loan.

(c) At any time before or after a Default or Unmatured Default, if the
Commitments shall have expired or be terminated while any Swing Line Loan is
outstanding, each Lender, at the sole option of the Swing Line Lender, shall either
(A) notwithstanding the expiration or termination of the Commitments, make a Loan as
a Floating Rate Advance, which such Loan shall be deemed a “Loan” for all
purposes of this Agreement and the other Loan Documents, or (B) be deemed, without
further action by any Person, to have purchased from the Swing Line Lender a
participation in such Swing Line Loan, in either case in an amount equal to the
product of such Lender’s Pro Rata Share times the outstanding principal balance of
such Swing Line Loan. The Agent shall notify each such Lender of the amount of such
Loan or participation, and such Lender will transfer to the Agent for the account of
the Swing Line Lender on the next Business Day following such notice, in immediately
available funds, the amount of such Loan or participation.

(d) If any such Lender shall not have so made its Loan or its percentage
participation available to the Agent pursuant to this Section 2.1.2, such
Lender agrees to pay interest thereon for each day from such date until the date
such amount is paid at the lesser of (i) the Federal Funds Effective Rate for such
day for the first three days and thereafter the interest rate applicable to the
Loan, and (ii) the Highest Lawful Rate. Whenever, at any time after the Agent has
received from any Lender such Lender’s Loan or participating interest in a Swing
Line Loan, the Agent receives any payment on account thereof, the Agent will pay to
such Lender its participating interest in such amount (appropriately adjusted, in
the case of interest payments, to reflect the period of time during which such
Lender’s Loan or participating interest was outstanding and funded), which payment
shall be subject to repayment by such Lender if such payment received by the Agent
is required to be returned. Each Revolving Credit Lender’s obligation to make the
Loans or purchase such participating interests pursuant to this Section
2.1.2 shall be absolute and unconditional and shall not be affected by any
circumstance, including, without limitation, (A) any set-off, counterclaim,
recoupment, defense or other right which such Lender or any other Person may have
against the Swing Line Lender, the Agent or any other Person for any reason
whatsoever; (B) the occurrence or continuance of a Default or an Unmatured Default
or the termination of the Commitments; (C) the occurrence of any Material Adverse
Effect; (D) any breach of this Agreement by the Borrower or any other Lender; or (E)
any other circumstance, happening or event whatsoever, whether or not similar to any
of the foregoing. Each Swing Line Loan, once so participated by any Lender, shall
cease to be a Swing Line Loan with respect to that amount for purposes of this
Agreement, but shall continue to be a Loan.

2.2 Required Payments, Termination. The Borrower shall make the following mandatory
payments:

(a) The Aggregate Outstanding Credit Exposure and all other unpaid Obligations
shall be paid in full by the Borrower on the Facility Termination Date;

(b) Each Swing Line Loan shall be paid in full on the fifth Business Day from
the date such Swing Line Loan was made by the Swing Line Lender;

(c) Notwithstanding anything to the contrary contained in this Agreement or in
any other Loan Document, the Aggregate Outstanding Credit Exposure shall not exceed
the lesser of (i) the Aggregate Commitment and (ii) the Borrowing Base at any time
during the Restricted Period. The Lenders shall never be required to make any
Advance or issue or participate in any Facility LC, and the Swing Line Lender shall
never be required to make any Swing Line Loan, that would cause the Aggregate
Outstanding Credit Exposure to exceed the lesser of (A) the Aggregate Commitment and
(B) the Borrowing Base at any time during the Restricted Period, and no Lender shall
be required to make any Advance or issue or participate in any Facility LC that
would cause such Lender’s Outstanding Credit Exposure to exceed its individual,
total Commitment. If the Aggregate Outstanding Credit Exposure exceeds the lesser
of (1) the Aggregate Commitment and (2) the Borrowing Base at any time during the
Restricted Period, the Borrower shall, within 60 days after the earlier of (x)
receiving written notice thereof from the Agent or (y) actual knowledge of such
deficiency by an officer of the Borrower, repay the principal of the Revolving
Credit Loans in an amount equal to such excess. If after giving effect to any such
principal repayment there shall be in existence a Collateral Shortfall Amount,
Borrower shall immediately pay to the Agent such Collateral Shortfall Amount in
immediately available funds, which funds shall be held in the Facility LC Collateral
Account.

(d) The Borrower shall prepay the Swing Line Loans, or if the Swing Line Loans
have been repaid in full, prepay the Revolving Credit Loans, by an amount equal to:

(i) 100% of the Debt Incurrence Proceeds that the Borrower or any of
its Subsidiaries receives from each Debt Incurrence after the Effective Date
upon receipt of such Debt Incurrence Proceeds;

(ii) the total amount of any insurance proceeds or condemnation award
received by the Borrower or any of its Subsidiaries in excess of $5,000,000
by reason of theft, loss, physical destruction or damage, condemnation or
any other similar event with respect to any property or assets of the
Borrower or any of its Subsidiaries if such insurance proceeds are not
applied or contractually committed to rebuild, restore or replace the
damaged or destroyed property within 90 days of the receipt thereof;

(iii) upon the sale of either (x) any asset other than Permitted Asset
Sales or (y) any stock in any of the Borrower’s Subsidiaries allowed under
Section 6.13(e), in each case for $5,000,000 or more in cash
proceeds, the entire amount of the Net Cash Proceeds resulting therefrom,
provided that, notwithstanding the foregoing, the Borrower shall not be
required to make a prepayment under this clause (iii) to the extent
that (A) the Borrower advises the Agent at the time of the relevant sale
that it intends to use such cash proceeds to finance one or more
Acquisitions permitted under Section 6.24 or otherwise to reinvest
the proceeds thereof into the business of the Borrower and its Subsidiaries
within one year of receipt of such proceeds and (B) such cash proceeds are
in fact so applied to such Acquisitions permitted under Section 6.24
or reinvested within one year of such sale. Any non-cash proceeds received
from such sale shall be pledged as additional Collateral.

consist of Loans made from the several Lenders ratably according to their Pro Rata Shares.

2.4 Types of Advances. The Advances (other than Advances made in respect of a Swing Line
Loan which must be Floating Rate Advances) may be Floating Rate Advances or Eurodollar Advances, or
a combination thereof, selected by the Borrower in accordance with Section 2.8 and Section 2.9.

2.5 Commitment Fee, Reductions in Aggregate Commitment.

(a) The Borrower agrees to pay to the Agent for the account of each Lender
according to its Pro Rata Share a commitment fee at a per annum rate equal to the
Applicable Fee Rate on the average daily unused portion of Aggregate Commitment from
the date hereof to and including the Facility Termination Date, payable quarterly in
arrears on each Payment Date hereafter and on the Facility Termination Date.

(b) The Borrower may permanently reduce the Aggregate Commitment in whole, or
in part by reducing each of the Aggregate Revolving Credit Commitment and the
Aggregate Facility LC Commitment ratably among the Lenders in integral multiples of
$5,000,000, upon at least three Business Day’s written notice to the Agent, which
notice shall specify the amount of any such reduction, provided, however, that (i)
the amount of the Aggregate Commitment may not be reduced below the Aggregate
Outstanding Credit Exposure; (ii) the amount of the Aggregate Revolving Credit
Commitment shall not be reduced below the amount of outstanding Revolving Credit
Loans, and, (iii) the Aggregate Facility LC Commitment shall not be reduced below
the amount of the LC Obligations. All accrued commitment fees shall be payable on
the effective date of any termination of the obligations of the Lenders to make
Credit Extensions hereunder.

2.6 Minimum Amount of Each Advance. Each Eurodollar Advance shall be in the minimum amount
of $2,500,000 (and in multiples of $500,000 if in excess thereof), and each Floating Rate Advance
other than those constituting Swing Line Loans, shall be in the minimum amount of $2,500,000 (and
in multiples of $500,000 if in excess thereof), provided, however, that any Floating Rate Advance
may be in the amount of the remaining unused portion of the Aggregate Revolving Credit Commitment.

2.7 Optional Principal Payments. The Borrower may from time to time pay or prepay, without
penalty or premium, all outstanding Floating Rate Advances, or, in a minimum aggregate amount of
$2,500,000 or any integral multiple of $500,000 in excess thereof, any portion of the outstanding
Floating Rate Advances after giving notice to the Agent of such prepayment no later than 1:00 p.m.
New York time one Business Day prior to such prepayment. The Borrower may from time to time pay or
prepay, subject to the payment of any funding indemnification amounts required by Section 3.4 but
without penalty or premium, all outstanding Eurodollar Advances, or, in a minimum aggregate amount

outstanding Eurodollar Advances after giving notice to the Agent of such prepayment no later than
1:00 p.m. New York time three Business Days prior to such prepayment.

2.8 Method of Selecting Types and Interest Periods for New Advances.

2.8.1 Loans. The Borrower shall select the Type of Advance and, in the case of
each Eurodollar Advance, the Interest Period applicable thereto from time to time. The
Borrower shall give the Agent irrevocable notice (a “Borrowing Notice”) not later

Loans, it shall give written notice thereof (or telephonic notice promptly confirmed in writing) to

continue as Floating Rate Advances unless and until such Floating Rate Advances are converted into
Eurodollar Advances pursuant to this Section 2.9 or are repaid in accordance with Section 2.2 or

then applicable Interest Period therefor, at which time such Eurodollar Advance shall be
automatically converted into a Floating Rate Advance unless (a) such Eurodollar Advance is or was
repaid in accordance with Section 2.7 or (b) the Borrower shall have given the Agent a
Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest

converted into Eurodollar Advances.

2.10 Change in Interest Rate, etc. Each Floating Rate Advance shall bear interest on the
outstanding principal amount thereof, for each day from and including the date such Advance is made
or is automatically converted from a Eurodollar Advance into a Floating Rate Advance pursuant to
Section 2.9, to but excluding the date it is paid or is converted into a Eurodollar Advance (and on
which date, if a conversion has occurred, the Eurodollar Rate is charged), at a rate per annum
equal to the Floating Rate for such day. Changes in the rate of interest on that portion of any
Advance maintained as a Floating Rate Advance will take effect simultaneously with each change in
the Alternate Base Rate or Applicable Margin, as applicable. Each Eurodollar Advance shall bear
interest on the outstanding principal amount thereof from and including the first day of the
Interest Period applicable thereto to the last day of such Interest Period at the interest rate
determined by the Agent as applicable to such Eurodollar Advance based upon the Borrower’s
selections under Section 2.8 and Section 2.9 and otherwise in accordance with the terms hereof.

the Lenders to changes in interest rates), declare that no Advance may be made as, converted into
or continued as a Eurodollar Advance. Upon the occurrence and during the continuance of a Default
the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked
at the option of the Required Lenders notwithstanding any provision of Section 8.2 requiring
unanimous consent of the Lenders to changes in interest rates), declare that (i) each Eurodollar
Advance shall bear interest, after as well as before judgment, for the remainder of the applicable
Interest Period at the lesser of (x) the Eurodollar Rate calculated by adding the Applicable Margin
for Level V (as set forth on the Pricing Schedule) plus 2% per annum and (y) the Highest Lawful
Rate, (ii) each Floating Rate Advance shall bear interest, after as well as before judgment, at a
rate per annum equal to the lesser of (x) the Floating Rate calculated by adding the Applicable
Margin for Level V plus 2% per annum and (y) the Highest Lawful Rate and (iii) the LC Fee shall be
calculated by using the Applicable Margin for Level V increased by 2% per annum, provided that,
during the continuance of a Default under Section 7.6 or Section 7.7, the interest rates set forth
in clauses (i) and (ii) above and the increase in the LC Fee set forth in clause (iii) above shall
be applicable to all Credit Extensions without any election or action on the part of the Agent or
any Lender. Default interest shall be payable on demand.

equally, to an Issuer, in the case of payments required to be made by the Borrower to an Issuer
pursuant to Section 2.19.6.

2.13 Noteless Agreement, Evidence of Indebtedness.

(a) Each Lender shall maintain in accordance with its usual practice an account

amount of each Loan made hereunder, the Type thereof and the Interest Period with
respect thereto, (ii) the amount of any principal or interest due and payable or to
become due and payable from the Borrower to each Lender hereunder, (iii) the

existence and amounts of the Obligations therein recorded, provided, however, that
the failure of the Agent or any Lender to maintain such accounts or any error

“Note”). In such event, the Borrower shall prepare, execute and deliver to
such Lender a Note payable to the order of such Lender in the form of Exhibit
2.13(d) attached hereto. Thereafter, the Loans evidenced by such Note and
interest thereon shall at all times (including after any assignment pursuant to
Section 12.3) be represented by one or more Notes payable to the order of
the payee named therein or any assignee pursuant to Section 12.3, except to
the extent that any such Lender or assignee subsequently returns any such Note for
cancellation and requests that such Loans once again be evidenced as described in

2.14 Telephonic Notices. The Borrower hereby authorizes the Lenders and the Agent to
extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds
based on telephonic notices made by any person or persons the Agent or any Lender in good faith
believes to be acting on behalf of the Borrower, it being understood that the foregoing
authorization is specifically intended to allow Borrowing Notices and Conversion/Continuation
Notices to be given telephonically. The Borrower agrees to deliver promptly to the Agent a written
confirmation of each telephonic notice signed by an Authorized Officer of the Borrower. If the
written confirmation differs in any material respect from the action taken by the Agent and the
Lenders, the records of the Agent and the Lenders shall govern absent manifest error.

2.15 Interest Payment Dates, Interest and Fee Basis. Interest accrued on each Floating
Rate Advance shall be payable on each Payment Date, commencing with the first such date to occur
after the Effective Date, on any date on which the Floating Rate Advance is prepaid, whether due to
acceleration or otherwise, and at maturity. Interest accrued on that portion of the outstanding
principal amount of any Floating Rate Advance converted into a Eurodollar Advance on a day other
than a Payment Date shall be payable on the date of conversion. Interest accrued on each
Eurodollar Advance shall be payable in arrears on the last day of its applicable Interest Period,
on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and
at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than
three months shall also be payable on the last day of each three-month interval during such
Interest Period, and upon any prepayment. Interest on Floating Rate Advances shall be calculated
for actual days elapsed on the basis of a 365/366-day year. Interest on Eurodollar Advances,
commitment fees and LC Fees shall be calculated for actual days elapsed on the basis of a 360-day
year. Interest shall be payable for the day an Advance is made but not for the day of any payment
on the amount paid if payment is received prior to noon (local time) at the place of payment. If
any payment of principal of or interest on an Advance shall become due on a day which is not a
Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a
principal payment, such extension of time shall be included in computing interest in connection
with such payment. Notwithstanding the foregoing, the Borrower will pay to the Agent, for the
account of each Lender, interest at the applicable rate in accordance with Section 2.11.

2.16 Notification of Advances, Interest Rates, Prepayments and Commitment Reductions.
Promptly after receipt thereof, the Agent will notify each Lender of the contents of each Aggregate
Commitment reduction notice, Commitment increase notice, Borrowing Notice, Conversion/Continuation
Notice, and repayment notice received by it hereunder. Promptly after notice from an Issuer, the
Agent will notify each Lender of the contents of each request for issuance of a Facility LC
hereunder. The Agent will notify each Lender of the interest rate applicable to each Eurodollar
Advance promptly upon determination of such interest rate and will give each Lender prompt notice
of each change in the Alternate Base Rate.

2.17 Lending Installations. Each Lender may book its Loans and its participation in any LC
Obligations and an Issuer may book the Facility LCs at any Lending Installation selected by such
Lender or such Issuer, as the case may be, and may change its Lending Installation from time to
time. All terms of this Agreement shall apply to any such Lending Installation and the Loans,
Facility LCs, participations in LC Obligations and any Notes issued hereunder shall be deemed held
by each Lender or each Issuer, as the case may be, for the benefit of any such Lending
Installation. Each Lender and each Issuer may, by written notice to the Agent and the Borrower in
accordance with Article XIII, designate replacement or additional Lending Installations through
which Loans will be made by it or Facility LCs will be issued by it and for whose account Loan
payments or payments with respect to Facility LCs are to be made.

2.18 Non-Receipt of Funds by the Agent. Unless the Borrower or a Lender, as the case may
be, notifies the Agent prior to the time and date on which it is scheduled to make payment to the
Agent of (a) in the case of a Lender, the proceeds of a Loan or (b) in the case of the Borrower, a
payment of principal, interest or fees to the Agent for the account of the Lenders, that it does
not intend to make such payment, the Agent may assume that such payment has been made. The Agent
may, but shall not be obligated to, make the amount of such payment available to the intended
recipient in reliance upon such assumption. If such Lender or the Borrower, as the case may be,
has not in fact made such payment to the Agent, the recipient of such payment shall, on demand by
the Agent, repay to the Agent the amount so made available together with interest thereon in
respect of each day during the period commencing on the date such amount was so made available by
the Agent until the date the Agent recovers such amount at a rate per annum equal to (x) in the
case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days
and, thereafter, the interest rate applicable to the relevant Loan or (y) in the case of payment by
the Borrower, the interest rate applicable to the relevant Loan.

2.19 Facility LCs.

2.19.1 Issuance. The parties hereto acknowledge that on and after the
Effective Date the Existing Facility LCs shall be Facility LCs issued by an Issuer pursuant
to this Agreement. Facility LCs issued hereunder may be issued in any Agreed Currency.
Each Issuer hereby agrees, on the terms and conditions set forth in this Agreement, to issue
Financial Letters of Credit and Performance Letters of Credit (each, a “Facility
LC”) and to renew, extend, increase, decrease or otherwise modify each Facility LC
(“Modify” and each such action, a “Modification”), from time to time from
and including the Effective Date and prior to the fifteenth Business Day prior to the
Facility Termination Date upon the request of the Borrower; provided that immediately after
each such Facility LC is issued or Modified, (i) the aggregate outstanding principal amount
of the Loans plus the aggregate Dollar Amount of the outstanding Financial LC
Obligations shall not exceed the Aggregate Revolving Credit and Financial LC Commitment and
(ii) (1) the Aggregate Outstanding Credit Exposure shall not exceed the Aggregate Commitment
during any Unrestricted Period and (2) the Aggregate Outstanding Credit Exposure shall not
exceed the lesser of (A) the Aggregate Commitment and (B) the Borrowing Base at any time
during any Restricted Period (subject to Section 2.2(c)). No Facility LC issued on
or after the Effective Date shall have an expiry date later than the earlier of (x) the
fifth Business Day prior to the Facility Termination Date and (y) one year after its
issuance; provided that any Facility LC may provide for the renewal thereof for additional
one-year periods (which shall in no event extend beyond the fifth Business Day prior to the
Facility Termination Date).

2.19.2 Participations. Immediately upon the issuance or Modification by an Issuer of a
Facility LC in accordance with this Section 2.19, such Issuer shall be deemed, without
further action by any party hereto, to have unconditionally and irrevocably sold to each Lender,
and each Lender shall be deemed, without further action by any party hereto, to have
unconditionally and irrevocably purchased from such Issuer, an undivided interest and participation
in such Facility LC (and each Modification thereof and the related LC Obligations in proportion to
its Pro Rata Share), the Obligations of the Borrower in respect thereof, and the liability of such
Issuer thereunder, in an amount equal to such Lender’s Pro Rata Share of the full amount of such
Facility LC.

2.19.3 Notice. Subject to Section 2.19.1, the Borrower shall give the applicable
Issuer and the Agent, notice prior to 10:00 a.m. New York, New York time at least five Business
Days prior to the proposed date of issuance or Modification of each Facility LC, specifying the
beneficiary, the proposed date of issuance (or Modification) and the expiry date of such Facility
LC, and describing the proposed terms of such Facility LC and the nature of the transactions
proposed to be supported thereby. Upon receipt of such notice, such Issuer shall promptly notify
the Agent, and the Agent shall promptly notify each Lender, of the contents thereof and of the
amount of such Lender’s participation in such proposed Facility LC. The issuance or Modification
by such Issuer of any Facility LC shall, in addition to the conditions precedent set forth in
Article IV (the satisfaction of which such Issuer shall have no duty to ascertain), be
subject to the conditions precedent that such Facility LC shall be satisfactory to such Issuer and
that the Borrower shall have executed and delivered such application agreement and/or such other
instruments and agreements relating to such Facility LC as such Issuer shall have reasonably
requested (each, a “Facility LC Application”). In the event of any conflict between the
terms of this Agreement and the terms of any Facility LC Application, the terms of this Agreement
shall control.

2.19.4 LC Fees. The Borrower shall pay to the Agent, for the account of the Lenders
ratably in accordance with their respective Pro Rata Shares, a fee on the amount of each Facility
LC available for drawing at a per annum rate equal to the Applicable LC Fee Rate, such fee to be
payable in quarterly arrears to the Agent for the ratable benefit of the Lenders (including each
Issuer), plus (without duplication of the fees provided for in connection with the Fronting Fee (as
defined below)), documentation and processing charges and other standard costs of issuance (such
fee an “LC Fee”). The Borrower shall also pay to each Issuer for its own account (a)
quarterly in arrears, a fronting fee (the “Fronting Fee”) at a rate per annum equal to
        .125% per annum on the amount of each Facility LC issued by such Issuer available for drawing, and
(b) documentary and processing charges in connection with the issuance or Modification of and draws
under Facility LCs in accordance with such Issuer’s standard schedule for such charges as in effect
from time to time with respect to the issuance, amendment, cancellation, negotiation or transfer of
each Letter of Credit and each drawing made thereunder. For purposes of calculating the LC Fee and
Fronting Fees hereunder, the face amount of each Facility LC made in an Agreed Currency other than
Dollars shall be at any time the Dollar Amount of such Facility LC as determined on the most recent
Computation Date with respect to such Facility LC.

2.19.5 Administration, Reimbursement by Lenders. Upon receipt from the beneficiary of any
Facility LC of any demand for payment under such Facility LC, the applicable Issuer shall notify
the Agent and the Agent shall promptly notify the Borrower and each other Lender as to the amount
to be paid by such Issuer as a result of such demand and the proposed payment date (the “LC
Payment Date”). The responsibility of each Issuer to the Borrower and each Lender shall be
only to determine that the documents (including each demand for payment) delivered under each
Facility LC issued by such Issuer in connection with such presentment shall be in conformity in all
material respects with such Facility LC. Each Issuer shall endeavor to exercise the same care in
the issuance and administration of the Facility LCs issued by it as it does with respect to letters
of credit in which no participations are granted, it being understood that in the absence of any
gross negligence or willful misconduct by such Issuer, each Lender shall be unconditionally and
irrevocably liable without regard to the occurrence of any Default or any condition precedent
whatsoever, to reimburse such Issuer on demand for (a) such Lender’s Pro Rata Share of the Dollar
Amount of each payment made by such Issuer under each Facility LC (such Dollar Amount to be
determined at the time of such payment by such Issuer) to the extent such amount is not reimbursed
by the Borrower pursuant to Section 2.19.6 below, plus (b) interest on the
foregoing amount to be reimbursed by such Lender, for each day from the date of such Issuer’s
demand for such reimbursement (or, if such demand is made after 10:00 a.m. New York, New York time
on such date, from the next succeeding Business Day) to the date on which such Lender pays the
amount to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Effective
Rate for the first three days and, thereafter, at a rate of interest equal to the rate applicable
to Floating Rate Advances.

2.19.6 Reimbursement by Borrower. The Borrower shall be irrevocably and unconditionally
obligated to reimburse each Issuer on or before the applicable LC Payment Date for the Dollar
Amount to be paid by such Issuer upon any drawing under any Facility LC such Dollar Amount to be
determined at the time of such payment by such Issuer, without presentment, demand, protest or
other formalities of any kind, in the currency in which such Facility LC was issued; provided that
neither the Borrower nor any Lender shall hereby be precluded from asserting any claim for direct
(but not consequential) damages suffered by the Borrower or such Lender to the extent, but only to
the extent, caused by (a) the willful misconduct or gross negligence of such Issuer in determining
whether a request presented under any Facility LC issued by it complied with the terms of such
Facility LC or (b) such Issuer’s failure to pay under any Facility LC issued by it after the
presentation to it of a request strictly complying with the terms and conditions of such Facility
LC. All Reimbursement Obligations shall bear interest, payable on demand, for each day until paid
at a rate per annum equal to (i) the rate applicable to Floating Rate Advances for such day if such
day falls on or before the applicable LC Payment Date and (ii) the sum of 2% plus the rate
applicable to Floating Rate Advances for such day if such day falls after such LC Payment Date.
Each Issuer will pay to each Lender ratably in accordance with its Pro Rata Share the Dollar Amount
of all amounts received by it from the Borrower for application in payment, in whole or in part, of
the Reimbursement Obligation in respect of any Facility LC issued by such Issuer, but only to the
extent such Lender has made payment to such Issuer in respect of such Facility LC pursuant to
Section 2.19.5. Subject to the terms and conditions of this Agreement (including without
limitation the submission of a Borrowing Notice in compliance with Section 2.8 and the
satisfaction of the applicable conditions precedent set forth in Article IV), the Borrower
may request an Advance hereunder for the purpose of satisfying any Reimbursement Obligation.

2.19.7 Obligations Absolute. The Borrower’s obligations under this Section 2.19
shall be absolute and unconditional under any and all circumstances and irrespective of any setoff,
counterclaim or defense to payment that the Borrower may have or have had against any Issuer, any
Lender or any beneficiary of a Facility LC. The Borrower further agrees with each Issuer and each
Lender that the Issuers and the Lenders shall not be responsible for, and the Borrower’s
Reimbursement Obligation in respect of any Facility LC 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, any of its Affiliates, the beneficiary of any Facility LC or
any financing institution or other party to whom any Facility LC may be transferred or any claims
or defenses whatsoever of the Borrower or of any of its Affiliates against the beneficiary of any
Facility LC or any such transferee. No Issuer shall 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 Facility LC. The Borrower agrees that any action taken or
omitted by any Issuer or any Lender under or in connection with each Facility LC and the related
drafts and documents, if done without gross negligence or willful misconduct, shall be binding upon
the Borrower and shall not put any Issuer or any Lender under any liability to the Borrower.
Nothing in this Section 2.19.7 is intended to limit the right of the Borrower to make a
claim against any Issuer for damages as contemplated by the proviso to the first sentence of
Section 2.19.6.

2.19.8 Actions of Issuer. Each Issuer shall be entitled to rely, and shall be fully
protected in relying, upon any Facility LC, 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 such Issuer. Each Issuer shall be
fully justified in failing or refusing to take any action under this Agreement unless it shall
first have received such advice or concurrence of the Required Lenders as it reasonably deems
appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against
any and all liability and expense which may be incurred by it by reason of taking or continuing to
take any such action. Notwithstanding any other provision of this Section 2.19, each
Issuer shall in all cases be fully protected in acting, or in refraining from acting, under this
Agreement in accordance with a request of the Required Lenders, and such request and any action
taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holders
of a participation in any Facility LC.

2.19.9 Indemnification. The Borrower hereby agrees to indemnify and hold harmless each
Lender, each Issuer and the Agent, and their respective directors, officers, agents and employees
from and against any and all claims and damages, losses, liabilities, costs or expenses which such
Lender, such Issuer or the Agent may incur (or which may be claimed against such Lender, such
Issuer or the Agent by any Person whatsoever) by reason of or in connection with the issuance,
execution and delivery or transfer of or payment or failure to pay under any Facility LC or any
actual or proposed use of any Facility LC, including, without limitation, any claims, damages,
losses, liabilities, costs or expenses which such Issuer may incur by reason of or in connection
with (a) the failure of any other Lender to fulfill or comply with its obligations to such Issuer
hereunder (but nothing herein contained shall affect any rights the Borrower may have against any
defaulting Lender) or (b) by reason of or on account of such Issuer issuing any Facility LC which
specifies that the term “Beneficiary” included therein includes any successor by operation
of law of the named Beneficiary, but which Facility LC does not require that any drawing by any
such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to such
Issuer, evidencing the appointment of such successor Beneficiary, provided that the Borrower shall
not be required to indemnify any Lender, any Issuer or the Agent for any claims, damages, losses,
liabilities, costs or expenses to the extent, but only to the extent, caused by (i) the willful
misconduct or gross negligence of any Issuer or (ii) any Issuer’s failure to pay under any Facility
LC after the presentation to it of a request strictly complying with the terms and conditions of
such Facility LC. Nothing in this Section 2.19.9 is intended to limit the obligations of
the Borrower under any other provision of this Agreement.

2.19.10 Lenders’ Indemnification. Each Lender shall, ratably in accordance with its Pro
Rata Share (determined at the time such indemnity is sought), indemnify each Issuer, its affiliates
and their respective directors, officers, agents and employees (to the extent not reimbursed by the
Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim,
demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or
willful misconduct or such Issuer’s failure to pay under any Facility LC after the presentation to
it of a request strictly complying with the terms and conditions of the Facility LC) that such
indemnitees may suffer or incur in connection with this Section 2.19 or any action taken or
omitted by such indemnitees hereunder.

2.19.11 Facility LC Collateral Account. The Borrower agrees that it will, upon the request
of the Agent or the Required Lenders and until the final expiration date of any Facility LC and
thereafter as long as any amount is payable to any Issuer or the Lenders in respect of any Facility
LC, maintain a special interest bearing collateral account pursuant to arrangements satisfactory to
the Agent (the “Facility LC Collateral Account”) at the Agent’s office at the address
specified pursuant to Article III, in the name of the Borrower but under the sole dominion
and control of the Agent, for the benefit of the Lenders and in which such Borrower shall have no
interest other than as set forth in Section 8.1. The Borrower hereby pledges, assigns and
grants to the Agent, on behalf of and for the ratable benefit of the Lenders and the Issuers, a
security interest in all of the Borrower’s right, title and interest in and to all funds which may
from time to time be on deposit in the Facility LC Collateral Account to secure the prompt and
complete payment and performance of the Obligations. Nothing in this Section 2.19.11 shall
either obligate the Agent to require the Borrower to deposit any funds in the Facility LC
Collateral Account or limit the right of the Agent to release any funds held in the Facility LC
Collateral Account in each case other than as required by Section 8.1.

2.19.12 Rights as a Lender. In its capacity as a Lender, an Issuer shall have
the same rights and obligations as any other Lender.

2.19.13 Agreed Currency Provisions. The Agent will determine the Dollar Amount
of the LC Obligations as of (a) the date five Business Days prior to the proposed date of
issuance or Modification and (b) on and as of the last Business Day of each fiscal quarter
of the Borrower and on any other Business Day at the Agent’s reasonable discretion or upon
instruction by the Required Lenders. Each day upon or as of which the Agent determines
Dollar Amounts as described in the preceding clauses (a) and (b) is herein described as a
“Computation Date”. If at any time the Dollar Amount of the sum of the aggregate principal
amount of all outstanding LC Obligations (calculated, with respect to those LC Obligations
denominated in Agreed Currencies other than Dollars, as of the most recent Computation Date)
exceeds (i) the Aggregate Facility LC Commitment during any Unrestricted Period or (ii) the
lesser of (1) the Aggregate Facility LC Commitment or (2) the Borrowing Base at any time
during any Restricted Period (subject to Section 2.2(c)), the Borrower shall
immediately make deposits to the Facility LC Collateral Account to the extent of the
Collateral Shortfall Amount.

2.20 Replacement of Lender. If the Borrower is required pursuant to Section 3.1, Section
3.2 or Section 3.5 to make any additional payment to any Lender or if any Lender’s obligation to
make or continue, or to convert Floating Rate Advances into, Eurodollar Advances shall be suspended
pursuant to Section 3.3 (any Lender so affected an “Affected Lender”), the Borrower may elect, with
the consent of the Issuers and the Swing Line Lender (each consent not to be unreasonably
withheld), if such amounts continue to be charged or such suspension is still effective, to replace
such Affected Lender as a Lender party to this Agreement, provided that no Default or Unmatured
Default shall have occurred and be continuing at the time of such replacement, and provided further
that, concurrently with such replacement, (a) another bank or other entity which is reasonably
satisfactory to the Borrower and the Agent shall agree, as of such date, to purchase for cash the
Advances and other Obligations due to the Affected Lender pursuant to an assignment substantially
in the form of Exhibit 12.3.1 and to become a Lender for all purposes under this Agreement and to
assume all obligations of the Affected Lender which as to the Affected Lender shall be terminated
as of such date and to comply with the requirements of Section 12.3 applicable to assignments, and
(b) the Borrower shall pay to such Affected Lender in same day funds on the day of such replacement
all interest, fees and other amounts then accrued but unpaid to such Affected Lender by the
Borrower hereunder to and including the date of termination, including without limitation payments
due to such Affected Lender under Section 3.1, Section 3.2 and Section 3.5.

ARTICLE III

YIELD PROTECTION; TAXES

3.1 Yield Protection.

(a) If any law or any governmental or quasi-governmental rule, regulation, policy,
guideline or directive (whether or not having the force of law), or any interpretation or
administration thereof by any governmental or quasi-governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or compliance
by any Lender or applicable Lending Installation with any request or directive (whether or
not having the force of law) of any such authority, central bank or comparable agency:

(i) subjects any Lender or any applicable Lending Installation or any Issuer to
any Taxes, or changes the basis of taxation of payments (other than with respect to
Excluded Taxes) to any Lender or any Issuer in respect of its Eurodollar Loans,
Facility LCs or participations therein, or

(ii) imposes or increases or deems applicable any reserve, assessment,
insurance charge, special deposit or similar requirement against assets of, deposits
with or for the account of, or credit extended by, any Lender or any applicable
Lending Installation or any Issuer (other than reserves and assessments taken into
account in determining the interest rate applicable to Eurodollar Advances), or

(iii) imposes any other condition the result of which is to increase the cost
to any Lender or any applicable Lending Installation or any Issuer of making,
funding or maintaining its Eurodollar Loans, or of issuing or participating in
Facility LCs, or reduces any amount receivable by any Lender or any applicable
Lending Installation or any Issuer in connection with its Eurodollar Loans, Facility
LCs or participations therein, or requires any Lender or any applicable Lending
Installation or any Issuer to make any payment calculated by reference to the amount
of Eurodollar Loans, Facility LCs or participations therein held or interest or LC
Fees received by it, by an amount deemed material by such Lender or any Issuer as
the case may be,

and the result of any of the foregoing is to increase the cost to such Lender or applicable
Lending Installation or such Issuer, as the case may be, of making or maintaining its
Eurodollar Loans, Commitment, or of issuing or participating in Facility LCs or to reduce
the return received by such Lender or applicable Lending Installation or such Issuer, as the
case may be, in connection with such Eurodollar Loans, Commitment, Facility LCs or
participations therein, then, within 3 days of demand by such Lender or such Issuer, as the
case may be, the Borrower shall pay such Lender or such Issuer, as the case may be, such
additional amount or amounts as will compensate such Lender or such Issuer, as the case may
be, for such increased cost or reduction in amount received. A Lender claiming compensation
under this section shall notify the Borrower in writing of such claim, and shall only be
entitled to compensation under this Section 3.1 for increased costs occurring (A)
from and after the date of such notice until the events giving rise to such claim have
ceased to exist, and (B) during the one hundred twenty (120) day period preceding the date
the Borrower receives notice from Agent or such Lender setting forth the described claim for
compensation.

(b) Borrower may, if obligated to make a payment under this Section 3.1,
require the Lender(s) collecting such payment to (i) to the extent reasonably possible,
change its Lending Installation to a different location so as to minimize such payment
obligation, so long as such designation would not, in the judgment of such Lender, result in
an increase in costs to such Lender or would otherwise be disadvantageous to such Lender, or
(ii) sell its interests herein to a Lender or other Person reasonably satisfactory to Agent
in accordance with Section 12.3.

3.2 Changes in Capital Adequacy Regulations.

(a) If a Lender or an Issuer determines the amount of capital required or expected to
be maintained by such Lender or such Issuer, any Lending Installation of such Lender or such
Issuer, or any corporation controlling such Lender or such Issuer is increased as a result
of a Change, then, within 3 days of demand by such Lender or such Issuer, the Borrower shall
pay such Lender or such Issuer the amount necessary to compensate for any shortfall in the
rate of return on the portion of such increased capital which such Lender or such Issuer
determines is attributable to this Agreement, its Outstanding Credit Exposure or its
Commitment to make Loans and issue or participate in Facility LCs, as the case may be,
hereunder (after taking into account such Lender’s or such Issuer’s policies as to capital
adequacy). “Change” means (i) any change after the Effective Date of this Agreement
in the Risk-Based Capital Guidelines or (ii) any adoption of or change in any other law,
governmental or quasi-governmental rule, regulation, policy, guideline, interpretation, or
directive (whether or not having the force of law) after the Effective Date which affects
the amount of capital required or expected to be maintained by any Lender or any Issuer or
any Lending Installation or any corporation controlling any Lender or any Issuer.
“Risk-Based Capital Guidelines” means (i) the risk-based capital guidelines in
effect in the United States on the Effective Date, including transition rules, and (ii) the
corresponding capital regulations promulgated by regulatory authorities outside the United
States implementing the July 1988 report of the Basle Committee on Banking Regulation and
Supervisory Practices Entitled “International Convergence of Capital Measurements and
Capital Standards,” including transition rules, and any amendments to such regulations
adopted prior to the Effective Date. A Lender claiming compensation under this section
shall notify the Borrower in writing of such claim, and shall only be entitled to
compensation under this Section 3.2 for increased costs as a result of a Change
occurring (A) from and after the date of such notice until the events giving rise to such
claim have ceased to exist, and (B) during the one hundred twenty (120) day period preceding
the date the Borrower receives notice from Agent or such Lender setting forth the described
claim for compensation resulting from such Change.

(b) Borrower may, if obligated to make a payment under this Section 3.2,
require the Lender(s) collecting such payment to (i) to the extent reasonably possible,
change its Lending Installation to a different location so as to minimize such payment
obligation, so long as such designation is not, in the judgment of such Lender,
disadvantageous to such Lender, or (ii) sell its interests herein to a Lender or other
Person reasonably satisfactory to Agent in accordance with Section 12.3.

3.3 Availability of Types of Advances. If any Lender determines that maintenance of its
Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule,
regulation, or directive, whether or not having the force of law, or if the Required Lenders
determine that (a) deposits of a type and maturity appropriate to match fund Eurodollar Advances
are not available or (b) the interest rate applicable to Eurodollar Advances does not accurately
reflect the cost of making or maintaining Eurodollar Advances, then the Agent shall suspend the
availability of Eurodollar Advances and require any affected Eurodollar Advances to be repaid or
converted to Floating Rate Advances, subject to the payment of any funding indemnification amounts
required by Section 3.4.

3.4 Funding Indemnification. If (i) any payment, conversion or (pursuant to Section 2.20)
assignment of a Eurodollar Advance occurs on a date which is not the last day of the applicable
Interest Period, whether because of acceleration, prepayment or otherwise or (ii) any Loan is not
made, prepaid or continued on the date specified by the Borrower for any reason other than default
by the Lenders, then the Borrower will indemnify each Lender for any loss or cost incurred by it
resulting therefrom, including, without limitation, any loss or cost in liquidating or employing
deposits acquired to fund or maintain such Eurodollar Advance.

3.5 Taxes.

(a) All payments by the Borrower to or for the account of any Lender, any Issuer or the
Agent hereunder or under any Note or Facility LC Application shall be made free and clear of
and without deduction for any and all Taxes. If the Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable hereunder to any Lender, any Issuer
or the Agent, (i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable under this
Section 3.5) such Lender, any Issuer or the Agent (as the case may be) receives an
amount equal to the sum it would have received had no such deductions been made, (ii) the
Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted
to the relevant authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Agent the original copy of a receipt evidencing payment thereof within 30
days after such payment is made.

(b) In addition, the Borrower hereby agrees to pay any present or future stamp or
documentary taxes and any other excise or property taxes, charges or similar levies which
arise from any payment made hereunder or under any Note or Facility LC Application or from
the execution or delivery of, or otherwise with respect to, this Agreement or any Note or
Facility LC Application (“Other Taxes”).

(c) The Borrower hereby agrees to indemnify the Agent, each Issuer and each Lender for
the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other
Taxes imposed on amounts payable under this Section 3.5) paid by the Agent, each
Issuer or such Lender and any liability (including penalties, interest and expenses) arising
therefrom or with respect thereto. Payments due under this indemnification shall be made
within 30 days of the date the Agent or such Lender makes demand therefor pursuant to
Section 3.6.

(d) Each Lender that is not incorporated under the laws of the United States of America
or a state thereof (each, a “Non-U.S. Lender”) agrees that it will, not less than
ten Business Days after the date it becomes a Lender, (i) deliver to each of the Borrower
and the Agent two duly completed copies of United States Internal Revenue Service Form
W-8BEN or W-8ECI or replacement or successor forms as the case may be, certifying in either
case that such Lender is entitled to receive payments under this Agreement without deduction
or withholding of any United States federal income taxes, and (ii) deliver to each of the
Borrower and the Agent a United States Internal Revenue Form W-8 or W-9 when it becomes a
Lender, as the case may be, and certify that it is entitled to an exemption from United
States backup withholding tax. Each Non-U.S. Lender further undertakes to deliver to each
of the Borrower and the Agent (A) renewals or additional copies of such form (or any
successor form) on or before the date that such form expires or becomes obsolete, and (B)
after the occurrence of any event requiring a change in the most recent forms so delivered
by it, such additional forms or amendments thereto as may be reasonably requested by the
Borrower or the Agent. All forms or amendments described in the preceding sentence shall
certify that such Lender is entitled to receive payments under this Agreement without
deduction or withholding of any United States federal income taxes, unless an event
(including without limitation any change in treaty, law or regulation) has occurred prior to
the date on which any such delivery would otherwise be required which renders all such forms
inapplicable or which would prevent such Lender from duly completing and delivering any such
form or amendment with respect to it and such Lender advises the Borrower and the Agent that
it is not capable of receiving payments without any deduction or withholding of United
States federal income tax.

(e) For any period during which a Non-U.S. Lender has failed to provide the Borrower
with an appropriate form pursuant to Section 3.5(c) above (unless such failure is
due to a change in treaty, law or regulation, or any change in the interpretation or
administration thereof by any governmental authority, occurring subsequent to the date on
which a form originally was required to be provided), such Non-U.S. Lender shall not be
entitled to indemnification under this Section 3.5 with respect to Taxes imposed by
the United States; provided that, should a Non-U.S. Lender which is otherwise exempt from or
subject to a reduced rate of withholding tax become subject to Taxes because of its failure
to deliver a form required under Section 3.5(c) above, the Borrower shall take such
steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S. Lender to
recover such Taxes.

(f) Any Lender that is entitled to an exemption from or reduction of withholding tax
with respect to payments under this Agreement or any Note pursuant to the law of any
relevant jurisdiction or any treaty shall deliver to the Borrower (with a copy to the
Agent), at the time or times prescribed by applicable law, such properly completed and
executed documentation prescribed by applicable law as will permit such payments to be made
without withholding or at a reduced rate.

(g) If the U.S. Internal Revenue Service or any other governmental authority of the
United States or any other country or any political subdivision thereof asserts a claim that
the Agent did not properly withhold tax from amounts paid to or for the account of any
Lender (because the appropriate form was not delivered or properly completed, because such
Lender failed to notify the Agent of a change in circumstances which rendered its exemption
from withholding ineffective, or for any other reason), such Lender shall indemnify the
Agent fully for all amounts paid, directly or indirectly, by the Agent as tax, withholding
therefor, or otherwise, including penalties and interest, and including taxes imposed by any
jurisdiction on amounts payable to the Agent under this subsection, together with all costs
and expenses related thereto (including attorneys fees and time charges of attorneys for the
Agent, which attorneys may be employees of the Agent). The obligations of the Lenders under
this Section 3.5(g) shall survive the payment of the Obligations and termination of
this Agreement.

(h) In the event that Borrower reimburses any Lender or the Agent for any Taxes or pays
any Taxes on any Lender’s or the Agent’s behalf pursuant to this Section 3.5 and
such Lender or Agent thereafter receives any refund or credit of such Taxes, such Lender or
Agent shall promptly pay Borrower the amount, as determined by such Lender in good faith, of
any such refund or credit that was actually received by such Lender as a consequence of such
refund; provided that the Lender shall not be required to make available its tax returns or
any other information relating to its taxes that it deems to be confidential.

3.6 Lender Statements; Survival of Indemnity. To the extent reasonably possible, each
Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to
reduce any liability of the Borrower to such Lender under Section 3.1, Section 3.2 and Section 3.5
or to avoid the unavailability of Eurodollar Advances under Section 3.3, so long as such
designation is not, in the judgment of such Lender, disadvantageous to such Lender. Each Lender
shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as to
the amount due, if any, under Section 3.1, Section 3.2, Section 3.4 or Section 3.5. Such written
statement shall set forth in reasonable detail the calculations upon which such Lender determined
such amount and shall be presumed correct in the absence of manifest error. Determination of
amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as
though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and
maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate
applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided
herein, the amount specified in the written statement of any Lender shall be payable on demand
after receipt by the Borrower of such written statement. The obligations of the Borrower under
Section 3.1, Section 3.2, Section 3.4 and Section 3.5 shall survive payment of the Obligations and
termination of this Agreement.

3.7 Effect of Yield Protection. The provisions of Section 3.1, Section 3.2, Section 3.3,
Section 3.4, Section 3.5 and Section 3.6 shall be interpreted in the broadest possible terms to
include any increased costs, payments or reduced income for any reason, including but specifically
not by way of limitation, due to taxes, capital adequacy provisions, reserve requirements,
withholding obligations, costs due to the payment of any sums on a date other than the regularly
scheduled date or for any other reason. The Borrower does hereby indemnify and hold harmless the
Agent and each Lender for all such costs and does hereby agree to pay same or cover the Agent’s or
any Lender’s expenses or losses in regard to same. The Borrower shall pay such sums to the Agent
or to any Lender as are necessary to mitigate all such items. This obligation is in addition to
all other Obligations of the Borrower hereunder.

ARTICLE V

REPRESENTATIONS AND WARRANTIES

The Borrower for itself and each of its Domestic Subsidiaries represents and warrants to the
Lenders that:

5.1 Existence and Standing. Each of the Borrower and its Subsidiaries is a corporation,
partnership (in the case of Subsidiaries only) or limited liability company duly and properly
incorporated or organized, as the case may be, validly existing and (to the extent such concept
applies to such entity) in good standing under the laws of its jurisdiction of incorporation or
organization and has all requisite authority to conduct its business in each jurisdiction in which
its business is conducted, except where the failure to so qualify would not have a Material Adverse
Effect.

5.2 Authorization and Validity. The Borrower and each of its Subsidiaries has the
requisite power and authority and legal right to execute and deliver the Loan Documents to which it
is a party and to perform its obligations thereunder. The execution and delivery by the Borrower
and each of its Subsidiaries of the Loan Documents to which it is a party and the performance of
its respective obligations thereunder have been duly authorized by proper corporate proceedings,
and the Loan Documents to which the Borrower and each of its Subsidiaries is a party constitute
legal, valid and binding obligations of such Person enforceable against such Person in accordance
with their terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws
affecting the enforcement of creditors’ rights generally.

5.3 No Conflict; Government Consent. Neither the execution and delivery by the Borrower or
any of its Domestic Subsidiaries of any of the Loan Documents to which it is a party, nor the
consummation of the transactions therein contemplated, nor compliance with the provisions thereof
will violate (a) any law, rule, regulation, order, writ, judgment, injunction, decree or award
binding on the Borrower or any of its Material Subsidiaries, except for such violations or defaults
as would not have a Material Adverse Effect or (b) the Borrower’s or any Subsidiary’s articles or
certificate of incorporation, partnership agreement, certificate of partnership, articles or
certificate of organization, by-laws, or operating or other management agreement, as the case may
be, or (c) the provisions of any indenture, instrument or agreement to which the Borrower or any of
its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or conflict
with or constitute a default thereunder, or result in, or require, the creation or imposition of
any Lien in, of or on the Property of the Borrower or any Subsidiary pursuant to the terms of any
such indenture, instrument or agreement, except for such conflicts, violations or defaults as would
not have a Material Adverse Effect. No order, consent, adjudication, approval, license,
authorization, or validation of, or filing, recording or registration with, or exemption by, or
other action in respect of any governmental or public body or authority, or any subdivision
thereof, which has not been obtained by the Borrower or any of its Domestic Subsidiaries, is
required to be obtained by the Borrower or any of its Subsidiaries in connection with the execution
and delivery of the Loan Documents, the borrowings under this Agreement, the payment and
performance by the Borrower of the Obligations, the performance by any Material Subsidiary of its
obligations under its Guaranty or the legality, validity, binding effect or enforceability of any
of the Loan Documents.

5.4 Financial Statements. (a) The audited consolidated balance sheets of the Borrower and
its Subsidiaries as at August 31, 2003 and August 31, 2004 and the related consolidated statements
of income, cash flow, and retained earnings of the Borrower and its Subsidiaries for each of the
fiscal years then ended, copies of which have been furnished to the Agent, and (b) the consolidated
balance sheets of the Borrower and its Subsidiaries as of and for each fiscal quarter in and the
portion of the fiscal year ending February 28, 2005 and the related consolidated statements of
income, cash flow, and retained earnings of the Borrower and its Subsidiaries, certified by the
chief financial officer of the Borrower, for each of such fiscal quarters, copies of which have
been furnished to the Agent, were prepared in accordance with generally accepted accounting
principles in effect on the date such statements were prepared and fairly present, in all material
respects, the consolidated financial condition and operations of the Borrower and its Subsidiaries
at such date and the consolidated results of their operations for the period then ended. The
Projections were prepared by the Borrower in good faith, based on assumptions that the Borrower
believes are reasonable as of the Effective Date.

5.5 Material Adverse Change. Since August 31, 2004, and except for matters disclosed by
the Borrower in writing in filings with the United States Securities and Exchange Commission
between August 31, 2004 and the date hereof, there has been no change in the business, Property,
condition (financial or otherwise) or prospects of the Borrower and its Subsidiaries taken as a
whole which could reasonably be expected to have a Material Adverse Effect.

5.6 Taxes. The Borrower and each of its Domestic Subsidiaries have filed all United States
federal tax returns and all other tax returns which are required to be filed and have paid all
taxes due pursuant to said returns or pursuant to any assessment received by the Borrower or any of
its Subsidiaries, except (a) such taxes, if any, as are being contested in good faith and as to
which adequate reserves have been provided in accordance with Agreement Accounting Principles and
as to which no Lien exists, and (b) for such failures to file or failures to pay as could not have
a Material Adverse Effect. No tax liens have been filed with respect to any such taxes. The
charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of any
taxes or other governmental charges are adequate in all material respects in accordance with
Agreement Accounting Principles.

5.7 Litigation and Contingent Obligations. Except as disclosed on Schedule 5.7, there is
no litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the
knowledge of any of their executive officers, threatened against or affecting the Borrower or any
of its Subsidiaries which could reasonably be expected to have a Material Adverse Effect that is
not covered by insurance or which seeks to prevent, enjoin or delay the making of any Credit
Extensions. Except as disclosed on Schedule 5.7, other than any liability incident to any
litigation, arbitration or proceeding which could not reasonably be expected to have a Material
Adverse Effect, the Borrower has no material contingent obligations not provided for or disclosed
in the financial statements referred to in Section 5.4 which should be disclosed under Agreement
Accounting Principles.

5.8 Subsidiaries. Schedule 5.8 contains an accurate list of all Subsidiaries of the
Borrower as of the date of this Agreement, setting forth for each Subsidiary (a) such Subsidiary’s

outstanding shares of Capital Stock or other ownership interests of such Subsidiaries have been (to
the extent such concepts are relevant with respect to such ownership interests) duly authorized and
issued and are fully paid and non-assessable.

5.9 ERISA. The Unfunded Liabilities of all Single Employer Plans do not in the aggregate
exceed $2,000,000. Neither the Borrower nor any other member of the Controlled Group has incurred,
or is reasonably expected to incur, any withdrawal liability to Multiemployer Plans in excess of
$2,000,000 in the aggregate. Each Plan complies in all material respects with all applicable
requirements of law and regulations, no Reportable Event has occurred with respect to any Plan that
could have a Material Adverse Effect, neither the Borrower nor any other member of the Controlled
Group has withdrawn from any Multiemployer Plan or initiated steps to do so, and no steps have been
taken to reorganize or terminate any Plan.

5.10 Accuracy of Information. No information, exhibit or report furnished by the Borrower
or any of its Subsidiaries to the Agent or to any Lender in connection with the negotiation of, or
compliance with, the Loan Documents contained any material misstatement of fact or omitted to state
a material fact or any fact necessary to make the statements contained therein not misleading.

5.11 Regulation T, U and X. The Loans and other transactions contemplated hereunder will
not violate the provisions of Regulations T, U or X.

5.12 Material Agreements. Except as disclosed on Schedule 5.12, neither the Borrower nor
any Subsidiary is a party to any loan transaction or guaranty of the Indebtedness of another Person
as of the Effective Date. Neither the Borrower nor any Subsidiary is a party to any agreement or
instrument or subject to any charter or other corporate restriction which could reasonably be
expected to have a Material Adverse Effect. Neither the Borrower nor any Subsidiary is in default
in the performance, observance or fulfillment of any of the obligations, covenants or conditions
contained in (a) any agreement to which it is a party, which default could reasonably be expected
to have a Material Adverse Effect or (b) any agreement or instrument evidencing or governing
Indebtedness in excess of $2,000,000.

5.13 Compliance With Laws. The Borrower and its Subsidiaries have complied with all
applicable statutes, rules, regulations, orders and restrictions of any domestic or foreign
government or any instrumentality or agency thereof having jurisdiction over the conduct of their
respective businesses or the ownership of their respective Property except where the failure to so
comply could not have a Material Adverse Effect.

5.14 Ownership of Properties. Except as set forth on Schedule 5.14, on the Effective Date,
the Borrower and its Subsidiaries will have good title, free of all Liens other than those
permitted by Section 6.15, to all of the Property and assets reflected in the Borrower’s most
recent consolidated financial statements provided to the Agent as owned by the Borrower and its
Subsidiaries.

“plan assets” within the meaning of 29 C.F.R. § 2510.3-101 of an employee benefit plan (as defined
in Section 3(3) of ERISA) which is subject to Title I of ERISA or any plan (within the meaning of
Section 4975 of the Code), and neither the execution of this Agreement nor the making of Credit
Extensions hereunder gives rise to a prohibited transaction that could have a Material Adverse
Effect within the meaning of Section 406 of ERISA or Section 4975 of the Code.

5.16 Environmental Matters. In the ordinary course of its business, the officers of the
Borrower consider the effect of Environmental Laws on the business of the Borrower and its
Subsidiaries, in the course of which they identify and evaluate potential risks and liabilities
accruing to the Borrower due to Environmental Laws. On the basis of this consideration, the
Borrower has concluded that any noncompliance, if any, of Borrower or any of its Subsidiaries with
Environmental Laws could not reasonably be expected to have a Material Adverse Effect. Neither the
Borrower nor any Subsidiary has received any notice to the effect that its operations are not in
material compliance with any of the requirements of applicable Environmental Laws or are the
subject of any federal or state investigation evaluating whether any remedial action is needed to
respond to a release of any toxic or hazardous waste or substance into the environment, which
non-compliance or remedial action could reasonably be expected to have a Material Adverse Effect.

company” or of a “subsidiary company” of a “holding company,” within the meaning of the Public
Utility Holding Company Act of 1935, as amended.

5.19 No Default. On the Effective Date, no Default or Unmatured Default will have occurred
or be continuing.

5.20 Post-Retirement Benefits. The present value of the expected cost of post-retirement
medical and insurance benefits payable by the Borrower and its Subsidiaries to its employees and
former employees, as estimated by the Borrower in accordance with procedures and assumptions deemed
reasonable by the Required Lenders, does not exceed $2,000,000.

5.21 Insurance. The certificate signed by the President or Chief Financial Officer of the
Borrower, that attests to the existence and adequacy of, and summarizes, the property and casualty
insurance program carried by the Borrower with respect to itself and its Subsidiaries and that has
been furnished by the Borrower to the Agent and the Lenders, is complete and accurate in all
material respects. This summary includes the insurer’s or insurers’ name(s), policy number(s),

This summary also includes similar information, and describes any reserves, relating to any

(a) After giving effect to the application of the proceeds of the Credit Extension on
the Effective Date, (i) the fair value of the assets of the Borrower and its Subsidiaries on
a consolidated basis, at a fair valuation, will exceed the debts and liabilities,
subordinated, contingent or otherwise, of the Borrower and its Subsidiaries on a
consolidated basis; (ii) the present fair saleable value of the Property of the Borrower and
its Subsidiaries on a consolidated basis will be greater than the amount that will be
required to pay the probable liability of the Borrower and its Subsidiaries on a
consolidated basis on their debts and other liabilities, subordinated, contingent or
otherwise, as such debts and other liabilities become absolute and matured; (iii) the
Borrower and its Subsidiaries on a consolidated basis will be able to pay their debts and
liabilities, subordinated, contingent or otherwise, as such debts and liabilities become
absolute and matured; and (iv) the Borrower and its Subsidiaries on a consolidated basis
will not have unreasonably small capital with which to conduct the businesses in which they
are engaged as such businesses are now conducted and are proposed to be conducted after the
Effective Date and as of the Effective Date.

(b) The Borrower does not intend to, or to permit any of its Subsidiaries to, and does
not believe that it or any of its Subsidiaries will, incur debts beyond its ability to pay
such debts as they mature, taking into account the timing of and amounts of cash to be
received by it or any such Subsidiary and the timing of the amounts of cash to be payable on
or in respect of its Indebtedness or the Indebtedness of any such Subsidiary.

5.23 Bond Obligations. As of the date set forth on Schedule 5.23, neither the Borrower nor
any of its Domestic Subsidiaries have any reimbursement or guaranty obligations owing to bonding
companies except as described on Schedule 5.23.

5.24 Intellectual Property. The Borrower and each of its Subsidiaries has obtained rights
to use all patents, trademarks, service marks, trade names, copyrights, licenses and other
intellectual property rights, except for such rights the failure to obtain any of which would not
reasonably be expected to have a Material Adverse Effect.

5.25 Revisions or Updates to the Schedules. Should any of the information or disclosures
provided on any of the schedules originally attached hereto become outdated or incorrect in any
material respect, the Borrower from time to time shall deliver to the Agent and the Lenders such
revisions or updates to such schedule(s) whereupon such schedules shall be deemed to be amended by
such revisions or updates, as may be necessary or appropriate to update or correct such
schedule(s), provided that, notwithstanding the foregoing, no such revisions or updates shall be
deemed to have amended, modified, or superseded any such schedules as originally attached hereto,
or to have cured any breach of warranty or representation resulting from the inaccuracy or
incompleteness of any such schedules, unless and until the Agent and the Required Lenders shall
have accepted in writing such revisions or updates to any such schedules.

5.26 Commercial Activity; Absence of Immunity. The Borrower and its Subsidiaries are
subject to civil and commercial law with respect to their respective obligations under the Loan
Documents and the making and performance of the Loan Documents by them constitute private and
commercial acts rather than public or governmental acts. None of the Borrower, its Subsidiaries or
any of their respective properties or revenues, is entitled to any immunity on the ground of
sovereignty or the like from the jurisdiction of any court or from any action, suit or proceeding,
or the service of process in connection therewith, arising under the Loan Documents.

each Mortgaged Property granting a Lien to the Agent in the Mortgaged Property identified in
Part A of Schedule 6.28 to secure the Obligations, together with any other
documents, agreements or instruments necessary to create an Acceptable Security Interest in
such Mortgaged Property; (ii) favorable opinions from local counsel located in the
jurisdiction of each Mortgaged Property covering such matters as the Agent may reasonably
request, in form and substance reasonably satisfactory to the Agent; (iii) ALTA lender’s
title insurance policies, or comparable policies if an ALTA policy is not available in a
particular state, issued by title insurers reasonably satisfactory to the Agent (the
“Mortgage Policies”) in form and substance and in amounts reasonably satisfactory to
the Agent assuring the Agent that the Mortgages are valid and enforceable first priority
mortgage liens on the respective Mortgaged Property, free and clear of all defects and
encumbrances except Permitted Liens; and (iv) surveys, certified by a licensed surveyor
in a form acceptable by the title company issuing the Mortgage Policies in order to
issue such Mortgage Policies in the form agreed to in clause (iii) of this
Section 6.28, for the real property listed on Part A of Schedule 6.28;
provided, however, that the Agent, shall at the request of the Borrower, grant a one-time
thirty day extension for the delivery of any of the items required by (i) through (iv)
above.

(b) Other Post-Closing Requirements. Within ninety days after the Effective
Date, the Borrower shall deliver to the Agent the documents identified in Part B and C of
Schedule 6.28, each in form and substance satisfactory to the Agent and with
sufficient copies for the Lenders, where appropriate, executed by the relevant Person;
provided that (i) with respect to the landlord’s agreements, the Borrower shall not be
required to deliver such agreements for locations that individually hold less than $500,000
of Inventory so long as the aggregate amount of Inventory held at such locations does not
exceed $5,000,000 at any time, and (ii) with respect to the account control agreements, the
Borrower shall not be required to deliver such agreements for bank accounts that
individually have an end-of-day balance of less than $100,000 so long as the aggregate
end-of-day balance of such bank accounts does not exceed $3,000,000 at any time.
Notwithstanding anything contained herein to the contrary, (x) the Borrower shall, at all
times, cause the value of Inventory held at locations not covered by landlord’s agreements
satisfactory to the Agent to be less than $500,000 at any one location and less than
$5,000,000 in the aggregate for all such locations, (y) the Borrower shall, at all times,
cause the deposits held in bank accounts not covered by bank account control agreements
satisfactory to the Agent to be less than $100,000 in any one bank account and less than
$3,000,000 in the aggregate for all such bank accounts, and (z) the Borrower hereby
acknowledges and agrees that neither the Agent nor any Lender waives or relinquishes any of
its respective rights or interests arising under the Loan Documents, including without
limitation, any security interest granted therein, by permitting the Borrower or any
Subsidiary to hold Inventory at a location that is not covered by landlord’s agreement or to
maintain a bank account that is not covered by a bank account control agreement. If any
Receivable is subject to the Assignment of Claims Act of 1940, as amended from time to time,
or any applicable law now or hereafter existing similar in effect thereto, or to any
provision prohibiting the assignment or requiring notice of or consent to such assignment
with respect to any Receivable, the Borrower shall, upon the request of either the Agent or
the Required Lenders, have such Receivables duly assigned to the Agent in compliance with
all applicable governmental requirements so that the Agent is recognized by the applicable
account debtor to have all of the rights of an assignee of such Receivable.

that is the subject of the Mortgage Policies for which a Mortgage Policy is issued.

ARTICLE VIII

ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

8.1 Acceleration; Facility LC Collateral Account.

(a) If any Default described in Section 7.6 or Section 7.7 occurs and
is continuing, the obligations of the Lenders to make Credit Extensions hereunder and the
obligation and power of each Issuer to issue Facility LCs shall automatically terminate and
the Obligations shall immediately become due and payable without any election or action on
the part of the Agent, any Issuer or any Lender and the Borrower will be and become thereby
unconditionally obligated, without any further notice, act or demand, to pay to the Agent an
amount in immediately available funds, which funds shall be held in the Facility LC
Collateral Account, equal to the difference of (i) the amount of LC Obligations at such
time, less (ii) the amount on deposit in the Facility LC Collateral Account at such time
which is free and clear of all rights and claims of third parties and has not been applied
against the Obligations (such difference, the “Collateral Shortfall Amount”). If
any other Default occurs and is continuing, the Required Lenders (or the Agent with the
consent of the Required Lenders) may (A) terminate or suspend the obligations of the Lenders
to make Credit Extensions hereunder and the obligation and power of each Issuer to issue
Facility LCs, or declare the Obligations and any affected Lender may declare the Rate
Hedging Obligations to be due and payable, or both, whereupon the Obligations shall become
immediately due and payable, without presentment, demand, protest or notice of any kind, all
of which the Borrower hereby expressly waives, and (B) upon notice to the Borrower and in
addition to the continuing right to demand payment of all amounts payable under this
Agreement, make demand on the Borrower to pay, and the Borrower will, forthwith upon such
demand and without any further notice or act, pay to the Agent the Collateral Shortfall
Amount, which funds shall be deposited in the Facility LC Collateral Account.

(b) If at any time while any Default has occurred and is continuing, the Agent
determines that the Collateral Shortfall Amount at such time is greater than zero, the Agent
may make demand on the Borrower to pay, and the Borrower will, forthwith upon such demand
and without any further notice or act, pay to the Agent the Collateral Shortfall Amount,
which funds shall be deposited in the Facility LC Collateral Account.

(c) The Agent may at any time or from time to time after funds are deposited in the
Facility LC Collateral Account, apply such funds to the payment of the Obligations and any
other amounts as shall from time to time have become due and payable by the Borrower to the
Lenders or the Issuers under the Loan Documents.

(d) At any time while any Default has occurred and is continuing, neither the Borrower
nor any Person claiming on behalf of or through the Borrower shall have any right to
withdraw any of the funds held in the Facility LC Collateral Account. After all of the
Obligations have been indefeasibly paid in full and the Aggregate Commitment has been
terminated, any funds remaining, in the Facility LC Collateral Account shall be returned by
the Agent to the Borrower or paid to whomever may be legally entitled thereto at such time.

(e) If, within 30 days after acceleration of the maturity of the Obligations or
termination of the obligations of the Lenders to make Credit Extensions and the obligation
and power of the Issuers to issue Facility LCs hereunder as a result of any Default (other
than any Default as described in Section 7.6 or Section 7.7 with respect to
the Borrower) and before any judgment or decree for the payment of the Obligations due shall
have been obtained or entered, the Required Lenders (in their sole discretion) shall so
direct, the Agent shall, by notice to the Borrower, rescind and annul such acceleration
and/or termination.

8.2 Amendments. Subject to the provisions of this Article VIII, the Required Lenders (or
the Agent with the consent in writing of the Required Lenders) and the Borrower may enter into
agreements supplemental hereto for the purpose of adding or modifying any provisions to the Loan
Documents or changing in any manner the rights of the Lenders or the Borrower hereunder or waiving
any Default hereunder; provided, however, that:

(a) no such supplemental agreement shall, without the consent of each Lender directly
affected thereby:

(i) reduce the amount or postpone or extend the mandatory payments required
under Section 2.2 or any other regularly scheduled payment of principal of
any Loan or any payment date for, or forgive all or any portion of the principal
amount thereof or any Reimbursement Obligation related thereto, or reduce the rate
or extend the time of payment of interest or fees on any Loan or any Reimbursement
Obligations related thereto;

(ii) increase the amount of such Lender’s Revolving Credit Commitment or the
Facility LC Commitment;

(iii) reduce the amount of such Lender’s Revolving Credit Commitment or the
Facility LC Commitment, except as otherwise provided in Section 2.5(b);

(iv) extend the termination date of any Revolving Credit Commitment or Facility
LC Commitment or the expiry date of any Facility LC beyond a date that is later than
the fifth Business Day prior to the Facility Termination Date; or

(v) amend Section 11.2 or alter the manner in which payments or
prepayments or principal, interest or other amounts shall be applied as among the
Lenders or Types of Loan;

(b) no such supplemental agreement shall, without the consent of all of the Lenders:

(i) reduce the percentage specified in the definition of “Required Lenders”;

(ii) amend this Section 8.2; and

(iii) release all or substantially all of the Guarantors of any Credit
Extension or, except as provided in the Collateral Documents, release substantially
all of the Collateral; provided, however, that any Guarantor or Collateral may be
released if such Guarantor or such Collateral is sold or transferred as permitted
under this Agreement or any other Loan Document. For purposes of this subsection,
“substantial” means any Collateral, the aggregate book value of which is worth an
amount equal to or greater than ten percent (10%) of the tangible net worth of
Borrower calculated pursuant to Agreement Accounting Principles and as of the
immediately preceding fiscal quarter end;

(c) No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent; and

(d) No amendment of any provision relating to any Issuer shall be effective without the
written consent of such Issuer.

Notwithstanding the foregoing, the Agent may waive payment of the fee required under
Section 12.3.2 without obtaining the consent of any other party to this Agreement.

8.3 Preservation of Rights. No delay or omission of the Lenders, the Issuers or the Agent
to exercise any right under the Loan Documents shall impair such right or be construed to be a
waiver of any Default or an acquiescence therein, and the making of a Credit Extension
notwithstanding the existence of a Default or the inability of the Borrower to satisfy the
conditions precedent to such Credit Extension shall not constitute any waiver or acquiescence. Any
single or partial exercise of any such right shall not preclude other or further exercise thereof
or the exercise of any other right, and no waiver, amendment or other variation of the terms,
conditions or provisions of the Loan Documents whatsoever shall be valid unless in writing signed
by the Lenders required pursuant to Section 8.2, and then only to the extent in such writing
specifically set forth. All remedies contained in the Loan Documents or by law afforded shall be
cumulative and all shall be available to the Agent, the Issuers and the Lenders until the
Obligations have been paid in full.

ARTICLE IX

GENERAL PROVISIONS

9.1 Survival of Representations. All representations and warranties of the Borrower
contained in this Agreement shall survive the making of the Credit Extensions herein contemplated.

9.2 Governmental Regulation. Anything contained in this Agreement to the contrary
notwithstanding, neither any Issuer nor any Lender shall be obligated to extend credit to the
Borrower in violation of any limitation or prohibition provided by any applicable statute or
regulation.

9.3 Headings. Section headings in the Loan Documents are for convenience of reference
only, and shall not govern the interpretation of any of the provisions of the Loan Documents.

9.4 Entire Agreement. The Loan Documents embody the entire agreement and understanding
among the Borrower, the Agent, the Issuers and the Lenders and supersede all prior agreements and
understandings among the Borrower, the Agent, the Issuers and the Lenders relating to the subject
matter thereof other than the Fee Letter. In the event of any conflict between the terms of this
Agreement and those of any other Loan Document, the terms of this Agreement shall control, subject
to the provisions of Section 9.15.

9.5 Several Obligations; Benefits of this Agreement. The respective obligations of the
Lenders hereunder are several and not joint and no Lender shall be the partner or agent of any
other (except to the extent to which the Agent is authorized to act as such) or shall be
responsible for any other Lender’s failure to make Loans as required hereby. The failure of any
Lender to perform any of its obligations hereunder shall not relieve any other Lender from any of
its obligations hereunder. This Agreement shall not be construed so as to confer any right or
benefit upon any Person other than the parties to this Agreement and their respective successors
and assigns, provided, however, that the parties hereto expressly agree that BNPPSC shall enjoy the
benefits of the provisions of Section 9.6, Section 9.9 and Section 10.11 to the extent specifically
set forth therein and shall have the right to enforce such provisions on its own behalf and in its
own name to the same extent as if it were a party to this Agreement.

9.6 Expenses; Indemnification.

(a) The Borrower shall reimburse the Agent and BNPPSC for any costs, internal charges
and reasonable out-of-pocket expenses (including attorneys’ and accountants’ fees and time
charges of attorneys and accountants for the Agent, which attorneys may be employees of the
Agent) paid or incurred by the Agent or BNPPSC in connection with the preparation,
negotiation, execution, delivery, syndication, review, amendment, modification, and
administration of the Loan Documents. The Borrower also agrees to reimburse the Agent,
BNPPSC, the Issuers and the Lenders for any costs, internal charges and out-of-pocket
expenses (including attorneys’ fees and time charges of attorneys for the Agent, BNPPSC, the
Issuers and the Lenders, which attorneys may be employees of the Agent, BNPPSC, the Issuers
or the Lenders) paid or incurred by the Agent, BNPPSC, the Issuers or any Lender in
connection with the collection and enforcement of the Loan Documents. Notwithstanding the
foregoing sentence, the Lenders shall only be reimbursed for the attorneys’ fees and time
charges of attorneys of one counsel that will represent all the Lenders unless (i) a
conflict arises such that the Lenders divergent interest can not be represented by one
counsel or (ii) it has been determined that special local counsel is necessary in connection
with the collection and enforcement of the Loan Documents. Expenses being reimbursed by the
Borrower under this Section include, without limitation, the cost and expense of an annual
on site inspection and audit of Borrower’s Inventory (or any other collateral the subject of
the Collateral Documents) and costs and expenses incurred in connection with the Reports
described in the following sentence. The Borrower acknowledges that from time to time the
Agent may prepare and may distribute to the Lenders (but shall have no obligation or duty to
prepare or to distribute to the Lenders) certain audit reports (the “Reports”)
pertaining to the Borrower’s assets for internal use by the Agent from information furnished
to it by or on behalf of the Borrower, after the Agent has exercised its rights of
inspection pursuant to this Agreement.

(b) The Borrower hereby further agrees to indemnify the Agent, BNPPSC, the Issuers,
each Lender, the Affiliates of each of the foregoing and their respective directors,
officers, employees, advisors and agents (collectively, the “Indemnitees”) against
all losses, claims, damages, penalties, judgments, liabilities and expenses (including,
without limitation, all expenses of litigation or preparation therefor whether or not the
Indemnitee is a party thereto) which any of them may pay or incur arising out of or relating
to this Agreement, the other Loan Documents, the transactions contemplated hereby or the
direct or indirect application or proposed application of the proceeds of any Credit
Extension hereunder, including any of such arising from any of said Indemnitees own
negligence or under any doctrine of strict liability, except to the extent that they are
determined in a final non-appealable judgment by a court of competent jurisdiction to have
resulted from the gross negligence or willful misconduct of Indemnitee seeking
indemnification. The obligations of the Borrower under this Section 9.6 shall
survive the termination of this Agreement.

(c) Numbers of Documents. All statements, notices, closing documents, and
requests hereunder shall be furnished to the Agent with sufficient counterparts so that the
Agent may furnish one to each of the Lenders.

9.7 Accounting. Except as provided to the contrary herein, all accounting terms used
herein shall be interpreted and all accounting determinations hereunder shall be made in accordance
with Agreement Accounting Principles, except that any calculation or determination which is to be
made on a consolidated basis shall be made for the Borrower and all its Subsidiaries, including
those Subsidiaries, if any, which are unconsolidated on the Borrower’s audited financial
statements. Notwithstanding anything in this Agreement to the contrary, for purposes of
calculating the net income, net worth, indebtedness, Receivables, Inventory, PPE and all other
amounts included in any financial ratio or test under this Agreement in each case of any Person in
the Consolidated Group other than the Borrower or its Subsidiaries (each such Person, a “FIN 46
Entity”), the portion of such FIN 46 Entity’s net income, net worth, indebtedness, Receivables,
Inventory, PPE or other such amount that shall be included in such calculation under this Agreement
for purposes of the Consolidated Group shall equal (a) the total amount of such FIN 46 Entity’s net
income, net worth, indebtedness or other such amount multiplied by (b) the percentage of such FIN
46 Entity’s voting Capital Stock (or, if no such Capital Stock exists, such FIN 46 Entity’s
ownership interest) that is directly or (through one or more Subsidiaries) indirectly held by the
Borrower.

9.8 Severability of Provisions. Any provision in any Loan Document that is held to be
inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be
inoperative, unenforceable, or invalid without affecting the remaining provisions in that
jurisdiction or the operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable.

9.9 Nonliability of Lenders. The relationship between the Borrower on the one hand and the
Lenders, the Issuers and the Agent on the other hand shall be solely that of borrower and lender.
Neither the Agent, BNPPSC, any Issuer nor any Lender shall have any fiduciary responsibilities to
the Borrower. Neither the Agent, BNPPSC, any Issuer nor any Lender undertakes any responsibility
to the Borrower to review or inform the Borrower of any matter in connection with any phase of the
Borrower’s business or operations. The Borrower agrees that neither the Agent, BNPPSC, any Issuer
nor any Lender shall have liability to the Borrower (whether sounding in tort, contract or
otherwise) for losses suffered by the Borrower in connection with, arising out of, or in any way
related to, the transactions contemplated and the relationship established by the Loan Documents,
or any act, omission or event occurring in connection therewith, unless it is determined in a final
non-appealable judgment by a court of competent jurisdiction that such losses resulted from the
gross negligence or willful misconduct of the party from which recovery is sought. Neither the
Agent, BNPPSC, any Issuer nor any Lender shall have any liability with respect to, and the Borrower
hereby waives, releases and agrees not to sue for, any special, indirect or consequential damages
suffered by the Borrower in connection with, arising out of, or in any way related to the Loan
Documents or the transactions contemplated thereby.

9.10 Confidentiality. Each Lender agrees to hold any confidential information which it may
receive from the Borrower pursuant to this Agreement in confidence, except for disclosure (a) to
its Affiliates and to other Lenders and their respective Affiliates, (b) to legal counsel,
accountants, and other professional advisors to such Lender or to a Transferee, (c) to regulatory
officials, (d) to any Person as required by law, regulation, or legal process, (e) to any Person in
connection with any legal proceeding to which such Lender is a party, (f) to such Lender’s direct
or indirect contractual counterparties in swap agreements or to legal counsel, accountants and
other professional advisors to such counterparties, and (g) permitted by Section 12.4.

9.11 Nonreliance. Each Lender hereby represents that it is not relying on or looking to
any margin stock (as defined in Regulation U of the Board of Governors of the Federal Reserve
System) for the repayment of the Credit Extensions provided for herein.

9.12 Disclosure. Each party hereto (a) acknowledges and agrees that the Agent, BNPPSC, any
Issuer or any Lender and/or their respective Affiliates from time to time may hold other
investments in, make other loans to or have other relationships with the Borrower and its
Subsidiaries, and (b) waives any liability of any such party to any other party hereto,
respectively, arising out of or resulting from such investments, loans or relationships other than
liabilities arising out of the gross negligence or willful misconduct of the party holding such
investment, making such other loan or having such other relationship with the Borrower and its
Subsidiaries.

9.13 Interest. Each provision in this Agreement and each other Loan Document is expressly
limited so that in no event whatsoever shall the amount paid, or otherwise agreed to be paid, to
the Agent or any Lender, or charged, contracted for, reserved, taken or received by the Agent or
any Lender, for the use, forbearance or detention of the money to be loaned under this Agreement or
any Loan Document or otherwise (including any sums paid as required by any covenant or obligation
contained herein or in any other Loan Document which is for the use, forbearance or detention of
such money), exceed that amount of money which would cause the effective rate of interest to exceed
the Highest Lawful Rate, and all amounts owed under this Agreement and each other Loan Document
shall be held to be subject to reduction to the effect that such amounts so paid or agreed to be
paid, charged, contracted for, reserved, taken or received which are for the use, forbearance or
detention of money under this Agreement or such Loan Document shall in no event exceed that amount
of money which would cause the effective rate of interest to exceed the Highest Lawful Rate.
Anything herein or in any Note or any other Loan Document to the contrary notwithstanding, the
Borrower shall not be required to pay unearned interest and the Borrower shall not be required to
pay interest on the Obligations at a rate in excess of the Highest Lawful Rate, and if the
effective rate of interest which would otherwise be payable hereunder, under such Note or such Loan
Documents would exceed the Highest Lawful Rate, or if any Lender or the holder of such Note shall
receive any unearned interest or shall receive monies that are deemed to constitute interest which
would increase the effective rate of interest payable by the Borrower hereunder or under such Note
or other Loan Documents to a rate in excess of the Highest Lawful Rate, then (a) the amount of
interest which would otherwise be payable by the Borrower shall be reduced to the amount allowed
under applicable law and (b) any unearned interest paid by the Borrower or any interest paid by the
Borrower in excess of the Highest Lawful Rate shall in the first instance be credited on the
principal of the Obligations of the Borrower (or if all such Obligations shall have been paid in
full, refunded to the Borrower). It is further agreed that, without limitation of the foregoing,
all calculations of the rate of interest contracted for, reserved, taken, charged or received by
any Lender under the Notes and the Obligations and under the other Loan Documents are made for the
purpose of determining whether such rate exceeds the Highest Lawful Rate, and shall be made, to the
extent permitted by usury laws applicable to such Lender, by amortizing, prorating and spreading in
equal parts during the period of the full stated term of the Notes and this Agreement all interest
at any time contracted for, charged or received by such Lender in connection therewith.
Furthermore, in the event that the maturity of any Obligation is accelerated or in the event of any
required or permitted prepayment, then such consideration that constitutes interest under
applicable law may never include more than the maximum amount allowed by applicable law and excess
interest, if any, provided for in this Agreement, any Note or otherwise shall be canceled
automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be
refunded to the Borrower.

9.14 Excess Share Certificates. The Agent and the Lenders acknowledge that circumstances
have required that the Borrower deliver to the Agent such stock certificates of Foreign
Subsidiaries, and in some cases, while the Borrower has agreed to pledge to the Agent and the
Lenders only 66% of the Capital Stock of first tier Foreign Subsidiaries, the Borrower has in fact
delivered to the Agent stock certificates representing, in some cases, 100% of the Capital Stock of
certain Foreign Subsidiaries. Each Lender and the Agent acknowledge and agree that in no event
shall the Agent or any Lender be deemed to have (and they each hereby disclaim and deny) any Lien
upon, security interest in or claim upon any shares of Capital Stock in excess of 66% thereof, and
the Agent and the Lenders agree to surrender such stock certificates as may evidence more than 66%
of the Capital Stock of any Foreign Subsidiary to the Borrower upon request of Borrower, in
exchange for a stock certificate representing 66% of the Capital Stock of any such Foreign
Subsidiary.

9.15 Survival of Prior Agreements. The rights and privileges afforded the Agent and BNPPSC
in the Fee Letter and in that letter agreement dated March 14, 2005 among BNPPSC, the Agent and the
Borrower, shall survive the execution of this Agreement and the Effective Date and Agent and BNPPSC
shall continue to be entitled to the benefits thereof.

ARTICLE X

THE AGENT

10.1 Appointment; Nature of Relationship. BNPP is hereby appointed by each of the Lenders
as its contractual representative (herein referred to as the “Agent”) hereunder and under each
other Loan Document, and each of the Lenders irrevocably authorizes the Agent to act as the
contractual representative of such Lender with the rights and duties expressly set forth herein and
in the other Loan Documents. The Agent agrees to act as such contractual representative upon the
express conditions contained in this Article X. Notwithstanding the use of the defined term
“Agent”, it is expressly understood and agreed that the Agent shall not have any fiduciary
responsibilities to any Lender by reason of this Agreement or any other Loan Document and that the
Agent is merely acting as the contractual representative of the Lenders with only those duties as
are expressly set forth in this Agreement and the other Loan Documents. In its capacity as the
Lenders’ contractual representative, the Agent (a) does not hereby assume any fiduciary duties to
any of the Lenders, (b) is a “representative” of the Lenders within the meaning of Section 9-105 of
the Uniform Commercial Code and (c) is acting as an independent contractor, the rights and duties
of which are limited to those expressly set forth in this Agreement and the other Loan Documents.
Each of the Lenders hereby agrees to assert no claim against the Agent on any agency theory or any
other theory of liability for breach of fiduciary duty, all of which claims each Lender hereby
waives.

10.2 Powers. The Agent shall have and may exercise such powers under the Loan Documents as
are specifically delegated to the Agent by the terms of each thereof, together with such powers as
are reasonably incidental thereto. The Agent shall have no implied duties to the Lenders, or any
obligation to the Lenders to take any action thereunder except any action specifically provided by
the Loan Documents to be taken by the Agent.

10.3 General Immunity. Neither the Agent nor any of its directors, officers, agents or
employees shall be liable to the Borrower, any Lenders or any Issuer for any action taken or
omitted to be taken by it or them hereunder or under any other Loan Document or in connection
herewith or therewith except to the extent such action or inaction is determined in a final
non-appealable judgment by a court of competent jurisdiction to have arisen from the gross
negligence or willful misconduct of such Person.

10.4 No Responsibility for Loans, Recitals, etc. Neither the Agent nor any of its
directors, officers, agents or employees shall be responsible for or have any duty to ascertain,
inquire into, or verify (a) any statement, warranty or representation made in connection with any
Loan Document or any borrowing hereunder; (b) the performance or observance of any of the covenants
or agreements of any obligor under any Loan Document, including, without limitation, any agreement
by an obligor to furnish information directly to each Lender; (c) the satisfaction of any condition
specified in Article IV, except receipt of items required to be delivered solely to the Agent; (d)
the existence or possible existence of any Default or Unmatured Default; (e) the validity,
enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any other
instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation,
perfection or priority of any Lien in any collateral security; or (g) the financial condition of
the Borrower or any guarantor of any of the Obligations or of any of the Borrower’s or any such
guarantor’s respective Subsidiaries. The Agent shall have no duty to disclose to the Lenders
information that is not required to be furnished by the Borrower to the Agent at such time, but is
voluntarily furnished by the Borrower to the Agent (either in its capacity as Agent or in its
individual capacity).

10.5 Action on Instructions of Lenders. The Agent shall in all cases be fully protected in
acting, or in refraining from acting, hereunder and under any other Loan Document in accordance
with written instructions signed by the Required Lenders or 100% of the Lenders where required
hereunder, and such instructions and any action taken or failure to act pursuant thereto shall be
binding on all of the Lenders. The Lenders hereby acknowledge that the Agent shall be under no
duty to take any discretionary action permitted to be taken by it pursuant to the provisions of
this Agreement or any other Loan Document unless it shall be requested in writing to do so by the
Required Lenders. The Agent shall be fully justified in failing or refusing to take any action
hereunder and under any other Loan Document unless it shall first be indemnified to its
satisfaction by the Lenders pro rata against any and all liability, cost and expense that it may
incur by reason of taking or continuing to take any such action.

10.6 Employment of Agents and Counsel. The Agent may execute any of its duties as Agent
hereunder and under any other Loan Document by or through employees, agents, and attorneys-in-fact
and shall not be answerable to the Lenders, except as to money or securities received by it or its
authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected
by it with reasonable care. The Agent shall be entitled to advice of counsel concerning the
contractual arrangement between the Agent and the Lenders and all matters pertaining to the Agent’s
duties hereunder and under any other Loan Document.

10.7 Reliance on Documents; Counsel. The Agent shall be entitled to rely upon any Note,
notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by
it to be genuine and correct and to have been signed or sent by the proper person or persons, and,
in respect to legal matters, upon the opinion of counsel selected by the Agent, which counsel may
be employees of the Agent.

10.8 Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and
indemnify the Agent ratably in proportion to their respective Commitments (or, if the Commitments
have been terminated, in proportion to their Commitments immediately prior to such termination)
(determined at the time such indemnity is sought) (a) for any amounts not reimbursed by the
Borrower for which the Agent is entitled to reimbursement by the Borrower under the Loan Documents,
(b) for any other expenses incurred by the Agent on behalf of the Lenders, in connection with the
preparation, execution, delivery, administration and enforcement of the Loan Documents (including,
without limitation, for any expenses incurred by the Agent in connection with any dispute between
the Agent and any Lender or between two or more of the Lenders) and (c) for any liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted
against the Agent in any way relating to or arising out of the Loan Documents or any other document
delivered in connection therewith or the transactions contemplated thereby (including, without
limitation, for any such amounts incurred by or asserted against the Agent in connection with any
dispute between the Agent and any Lender or between two or more of the Lenders), or the enforcement
of any of the terms of the Loan Documents or of any such other documents, including any of such
arising from the Agent’s own negligence or under any doctrine of strict liability, in each case in
the Agent’s capacity as such, provided that (i) no Lender shall be liable for any of the foregoing
to the extent any of the foregoing is found in a final non-appealable judgment by a court of
competent jurisdiction to have resulted from the gross negligence or willful misconduct of the
Agent and (ii) any indemnification required pursuant to Section 3.5(f) shall, notwithstanding the
provisions of this Section 10.8, be paid by the relevant Lender in accordance with the provisions
thereof. The obligations of the Lenders under this Section 10.8 shall survive payment of the
Obligations and termination of this Agreement.

10.9 Notice of Default. The Agent shall not be deemed to have knowledge or notice of the
occurrence of any Default or Unmatured Default hereunder unless the Agent has received written
notice from a Lender or the Borrower referring to this Agreement describing such Default or
Unmatured Default and stating that such notice is a “notice of default.” In the event that the
Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders. Receipt
by Agent of a notice of termination from any of the Guarantors under the “Termination” Section of
the Guaranty shall be a notice of default.

10.10 Rights as a Lender. In the event the Agent is a Lender, the Agent shall have the
same rights and powers hereunder and under any other Loan Document with respect to its Commitment
and its Credit Extensions as any Lender and may exercise the same as though it were not the Agent,
and the term “Lender” or “Lenders” shall, at any time when the Agent is a Lender, unless the
context otherwise indicates, include the Agent in its individual capacity. The Agent and its
Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust,
debt, equity or other transaction, in addition to those contemplated by this Agreement or any other
Loan Document, with the Borrower or any of its Subsidiaries in which the Borrower or such
Subsidiary is not restricted hereby from engaging with any other Person. The Agent, in its
individual capacity, is not obligated to remain a Lender.

10.11 Lender Credit Decision. Each Lender acknowledges that it has, independently and
without reliance upon the Agent, BNPPSC or any other Lender and based on the financial statements
prepared by the Borrower and such other documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement and the other Loan
Documents. Each Lender also acknowledges that it will, independently and without reliance upon the
Agent, BNPPSC or any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or not taking action
under this Agreement and the other Loan Documents.

10.12 Successor Agent. The Agent may resign at any time by giving written notice thereof
to the Lenders and the Borrower, such resignation to be effective upon the appointment of a
successor Agent or, if no successor Agent has been appointed, forty-five days after the retiring
Agent gives notice of its intention to resign. The Agent may be removed at any time with or
without cause by written notice received by the Agent from the Required Lenders, such removal to be
effective on the date specified by the Required Lenders. Upon any such resignation or removal, the
Required Lenders shall have the right to appoint, on behalf of the Borrower and the Lenders, a
successor Agent. If no successor Agent shall have been so appointed by the Required Lenders within
thirty days after the resigning Agent’s giving notice of its intention to resign, then the
resigning Agent may appoint, on behalf of the Borrower and the Lenders, a successor Agent.
Notwithstanding the previous sentence, the Agent may at any time without the consent of the
Borrower or any Lender, appoint any of its Affiliates which is a commercial bank as a successor
Agent hereunder. If the Agent has resigned or been removed and no successor Agent has been
appointed, the Lenders may perform all the duties of the Agent hereunder and the Borrower shall
make all payments in respect of the Obligations to the applicable Lender and for all other purposes
shall deal directly with the Lenders. No successor Agent shall be deemed to be appointed hereunder
until such successor Agent has accepted the appointment. Any such successor Agent shall be a
commercial bank having capital and retained earnings of at least $100,000,000. 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 resigning or
removed Agent. Upon the effectiveness of the resignation or removal of the Agent, the resigning or
removed Agent shall be discharged from its duties and obligations hereunder and under the Loan
Documents. After the effectiveness of the resignation or removal of an Agent, the provisions of
this Article X shall continue in effect for the benefit of such Agent in respect of any actions
taken or omitted to be taken by it while it was acting as the Agent hereunder and under the other
Loan Documents. In the event that there is a successor to the Agent by merger, or the Agent
assigns its duties and obligations to an Affiliate pursuant to this Section 10.12, then the term
“Corporate Base Rate” as used in this Agreement shall mean the prime rate, base rate or other
analogous rate of the new Agent.

10.13 Agent’s Fee. The Borrower agrees to pay to the Agent, for its own account, the fees
agreed to by the Borrower and the Agent pursuant to the Fee Letter, or as otherwise agreed from
time to time.

10.14 Delegation to Affiliates. The Borrower and the Lenders agree that the Agent may
delegate any of its duties under this Agreement to any of its Affiliates. Any such Affiliate (and
such Affiliate’s directors, officers, agents and employees) which performs duties in connection
with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other
protective provisions to which the Agent is entitled under Article IX and Article X.

10.15 Execution of Collateral Documents. The Lenders hereby empower and authorize the
Agent to execute and deliver to the Borrower on their behalf the Collateral Documents and all
related financing statements and any financing statements, agreements, documents or instruments as
shall be necessary or appropriate to effect the purposes of the Collateral Documents.

10.16 Collateral Releases. The Lenders hereby empower and authorize the Agent to execute
and deliver to the Borrower on their behalf any agreements, documents or instruments as shall be
necessary or appropriate to effect any releases of Collateral which shall be permitted by the terms
hereof or of any other Loan Document or which shall otherwise have been approved by the Required
Lenders (or, if required by the terms of Section 8.2, all of the Lenders) in writing.

ARTICLE XI

SETOFF; RATABLE PAYMENTS

11.1 Setoff. In addition to, and without limitation of, any rights of the Lenders under
applicable law, if the Borrower becomes insolvent, however evidenced, or any Default occurs, any
and all deposits (including all account balances, whether provisional or final and whether or not
collected or available) and any other Indebtedness at any time held or owing by any Lender or any
Affiliate of any Lender to or for the credit or account of the Borrower may be offset and applied
toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any
part hereof, shall then be due.

11.2 Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to
it upon its Outstanding Credit Exposure (other than payments received pursuant to Section 3.1,
Section 3.2, Section 3.4 or Section 3.5) in a greater proportion than that received by any other
Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Aggregate
Outstanding Credit Exposure held by the other Lenders so that after such purchase each Lender will
hold its Pro Rata Share of the Aggregate Outstanding Credit Exposure. If any Lender, whether in
connection with setoff or amounts which might be subject to setoff or otherwise, receives
collateral or other protection for its Obligations or such amounts which may be subject to setoff,
such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share
in the benefits of such collateral ratably in proportion to their respective Pro Rata Shares of the
Aggregate Outstanding Credit Exposure. In case any such payment is disturbed by legal process, or
otherwise, appropriate further adjustments shall be made.

ARTICLE XII

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

12.1 Successors and Assigns. The terms and provisions of the Loan Documents shall be
binding upon and inure to the benefit of the Borrower and the Lenders and their respective
successors and assigns, except that (a) the Borrower shall not have the right to assign its rights
or obligations under the Loan Documents and (b) any assignment by any Lender must be made in
compliance with Section 12.3. Notwithstanding clause (b) of this Section, any Lender may at any
time, without the consent of the Borrower or the Agent, assign all or any portion of its rights
under this Agreement and any Note to a Federal Reserve Bank; provided, however, that no such
assignment to a Federal Reserve Bank shall release the transferor Lender from its obligations
hereunder. The Agent may treat the Person which made any Credit Extension or which holds any Note
as the owner thereof for all purposes hereof unless and until such Person complies with Section
12.3 in the case of an assignment thereof or, in the case of any other transfer, a written notice
of the transfer is filed with the Agent. Any assignee or transferee of the rights to any Credit
Extension or any Note agrees by acceptance of such transfer or assignment to be bound by all the
terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who
at the time of making such request or giving such authority or consent is the owner of the rights
to any Credit Extension (whether or not a Note has been issued in evidence thereof), shall be
conclusive and binding on any subsequent holder, transferee or assignee of the rights to such
Credit Extension.

12.2 Participations.

12.2.1 Permitted Participants; Effect. Any Lender may, in the ordinary course
of its business and in accordance with applicable law, at any time sell to one or more banks
or other entities (“Participants”) participating interests in any Outstanding Credit
Exposure of such Lender, any Note held by such Lender, any Commitment of such Lender or any
other interest of such Lender under the Loan Documents. In the event of any such sale by a
Lender of participating interests to a Participant, such Lender’s obligations under the Loan
Documents shall remain unchanged, such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, such Lender shall remain the owner
of its Outstanding Credit Exposure and the holder of any Note issued to it in evidence
thereof for all purposes under the Loan Documents, all amounts payable by the Borrower under
this Agreement shall be determined as if such Lender had not sold such participating
interests, and the Borrower and the Agent shall continue to deal solely and directly with
such Lender in connection with such Lender’s rights and obligations under the Loan
Documents.

12.2.2 Voting Rights. Each Lender shall retain the sole right to approve,
without the consent of any Participant, any amendment, modification or waiver of any
provision of the Loan Documents other than any amendment, modification or waiver with
respect to any Credit Extension or Commitment in which such Participant has an interest
which forgives principal, interest, or any Reimbursement Obligation or reduces the interest
rate or fees payable with respect to any such Credit Extension or Commitment, extends the
Facility Termination Date, postpones any date fixed for any regularly-scheduled payment of
principal of or interest on any Loan in which such Participant has an interest, or any
regularly-scheduled payment of fees on any such Credit Extension or Commitment, releases any
guarantor of any such Credit Extension or releases any Collateral held in the Facility LC
Collateral Account (except in accordance with the terms hereof) or all or substantially all
of any other Collateral, if any, securing any such Credit Extension.

12.2.3 Benefit of Setoff. The Borrower agrees that each Participant shall be
deemed to have the right of setoff provided in Section 11.1 in respect of its
participating interest in amounts owing under the Loan Documents to the same extent as if
the amount of its participating interest were owing directly to it as a Lender under the
Loan Documents, provided that each Lender shall retain the right of setoff provided in
Section 11.1 with respect to the amount of participating interests sold to each
Participant. The Lenders agree to share with each Participant, and each Participant, by
exercising the right of setoff provided in Section 11.1, agrees to share with each
Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to
be shared in accordance with Section 11.2 as if each Participant were a Lender.

12.3 Assignments.

12.3.1 Permitted Assignments. Any Lender may, in the ordinary course of its
business and in accordance with applicable law, at any time assign to one or more banks or
other entities (“Purchasers”) all or any part of its rights and obligations under
the Loan Documents, provided any such assignment must be of a Pro Rata Share of both the
Revolving Credit Commitment and the Facility LC Commitment of such assignor. Such
assignment shall be substantially in the form of Exhibit 12.3.1 or in such other
form as may be agreed to by the parties thereto. The consent of the Borrower, the Agent,
the Swing Line Lender and the Issuer shall be required prior to an assignment becoming
effective; provided if a Default has occurred and is continuing, or if the assignment is to
a Lender or an Affiliate thereof, the consent of the Borrower shall not be required. Such
consent shall not be unreasonably withheld or delayed; provided, however, that in the event
that the prospective assignee is unable or unwilling to deliver to the Borrower Forms W-8BEN
or W-8ECI (or successor forms, as applicable) demonstrating such assignee’s exemption from
United States Taxes with respect to all interest payments to be made to such assignee
hereunder, then such inability or unwillingness shall constitute a reasonable basis for
refusing to consent to such transfer. Each such assignment with respect to a Purchaser
which is not a Lender or an Affiliate thereof shall (unless each of the Borrower and the
Agent otherwise consents) be in an amount not less than the lesser of (i) $5,000,000 or (ii)
the remaining amount of the assigning Lender’s Commitment (calculated as at the date of such
assignment) or outstanding Credit Extensions (if the applicable Commitment has been
terminated), unless otherwise agreed by the Borrower and the Agent.

12.3.2 Effect; Effective Date. Upon (i) delivery to the Agent of an
assignment, together with any consents required by Section 12.3.1, and (ii) payment
of a $3,500 fee to the Agent for processing such assignment, such assignment shall become
effective on the effective date specified in such assignment. The assignment shall contain
a representation by the Purchaser to the effect that none of the consideration used to make
the purchase of the Commitment and Outstanding Credit Exposure under the applicable
assignment agreement constitutes “plan assets” as defined under ERISA and that the rights
and interests of the Purchaser in and under the Loan Documents will not be “plan assets”
under ERISA. On and after the effective date of such assignment, such Purchaser shall for
all purposes be a Lender party to this Agreement and any other Loan Document executed by or
on behalf of the Lenders and shall have all the rights and obligations of a Lender under the
Loan Documents, to the same extent as if it were an original party hereto, and no further
consent or action by the Borrower, the Lenders or the Agent shall be required to release the
transferor Lender with respect to the percentage of the Aggregate Commitment and Outstanding
Credit Exposure assigned to such Purchaser. Upon the consummation of any assignment to a
Purchaser pursuant to this Section 12.3.2, the transferor Lender, the Agent and the
Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be
evidenced by Notes, make appropriate arrangements so that new Notes or, as appropriate,
replacement Notes are issued to such transferor Lender and new Notes or, as appropriate,
replacement Notes, are issued to such Purchaser, in each case in principal amounts
reflecting their respective Commitments, as adjusted pursuant to such assignment.

12.3.3 Dissenting Lender. If any Lender shall inform the Agent that such
Lender (“Dissenting Lender”) will not consent to, or otherwise agree with, any
consent, waiver, amendment, supplement or other modification of any provisions of this
Agreement or any other Loan Document, or that such Dissenting Lender will not otherwise
agree with the decisions made by the Purchasing Lender (as defined below), the Lenders, the
Agent and the Borrower hereby agree that BNPP (or any successor Agent pursuant to the terms
hereof) in its individual capacity as a Lender (the “Purchasing Lender”) may, but
shall not be obligated to, with the Borrower’s consent, (a) purchase all of the Dissenting
Lenders’ rights and obligations under the Loan Documents pursuant to an assignment
substantially in the form of Exhibit 12.3.1 or in such other form as may be agreed
to by the parties thereto for cash consideration equal to 100% of the outstanding Advances,
interest, fees and other amounts then accrued but unpaid to such Dissenting Lender, (b)
assume all obligations of the Dissenting Lender under the Loan Documents which obligations
as to the Dissenting Lender shall be terminated as of such date, and (c) to comply with the
requirements of Section 12.3 applicable to such assignments; provided that, the
Borrower’s consent required under this Section shall not be unreasonably withheld and shall
not be required if an Event of Default has occurred and is continuing.

12.4 Dissemination of Information. The Borrower authorizes each Lender to disclose to any
Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by
operation of law (each, a “Transferee”) and any prospective Transferee any and all information in
such Lender’s possession concerning the creditworthiness of the Borrower and its Subsidiaries,
including without limitation any information contained in any Reports; provided that each
Transferee and prospective Transferee agrees to be bound by Section 9.10 of this Agreement.

12.5 Tax Treatment. If any interest in any Loan Document is transferred to any Transferee
which is organized under the laws of any jurisdiction other than the United States or any State
thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of
such transfer, to comply with the provisions of Section 3.5(c).

ARTICLE XIII

for service of notice upon it by a notice in writing to the other parties hereto.

ARTICLE XIV

COUNTERPARTS

ARTICLE XV

CHOICE OF LAW; CONSENT TO JURISDICTION;

WAIVER OF JURY TRIAL; ETC

15.1 CHOICE OF LAW THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING A CONTRARY EXPRESS
CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS (WITHOUT REGARD TO
THE CONFLICT OF LAWS PROVISIONS) OF THE STATE OF NEW YORK, BUT GIVING EFFECT TO FEDERAL LAWS
APPLICABLE TO NATIONAL BANKS. WITHOUT LIMITATION OF THE FOREGOING, NOTHING IN THIS AGREEMENT, OR
IN THE NOTES OR IN ANY OTHER LOAN DOCUMENT SHALL BE DEEMED TO CONSTITUTE A WAIVER OF ANY RIGHTS
WHICH ANY LENDER MAY HAVE UNDER APPLICABLE FEDERAL LEGISLATION RELATING TO THE AMOUNT OF INTEREST
WHICH SUCH LENDER MAY CONTRACT FOR, TAKE, RECEIVE OR CHARGE IN RESPECT OF THE LOAN AND THE LOAN
DOCUMENTS, INCLUDING ANY RIGHT TO TAKE, RECEIVE, RESERVE AND CHARGE INTEREST AT THE RATE ALLOWED BY
THE LAW OF THE STATE WHERE ANY LENDER IS LOCATED.

15.2 CONSENT TO JURISDICTION. THE BORROWER AND EACH GUARANTOR HEREBY IRREVOCABLY SUBMITS
TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR NEW YORK STATE COURT SITTING IN
NEW YORK, NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENTS AND
THE BORROWER AND EACH GUARANTOR HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION
OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT
MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A
COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE
AGENT, ANY ISSUER OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER OR ANY GUARANTOR IN THE
COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY THE BORROWER OR ANY GUARANTOR AGAINST
THE AGENT, ANY ISSUER, ANY LENDER OR ANY AFFILIATE OF THE AGENT, ANY ISSUER OR ANY LENDER

CONNECTED WITH ANY LOAN DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.

15.4 Judgment Currency. If for the purposes of obtaining judgment in any court it is
necessary to convert a sum due from the Borrower hereunder in the currency expressed to be payable
herein (the “specified currency”) into another currency, the parties hereto agree, to the fullest
extent that they may effectively do so, that the rate of exchange used shall be that at which in
accordance with normal banking procedures the Agent could purchase the specified currency with such
other currency at the Agent’s main New York office on the Business Day preceding that on which
final, non-appealable judgment is given. The obligations of the Borrower in respect of any sum due
to any Lender, any Issuer or the Agent hereunder shall, notwithstanding any judgment in a currency
other than the specified currency, be discharged only to the extent that on the Business Day
following receipt by such Lender, such Issuer or the Agent (as the case may be) of any sum adjudged
to be so due in such other currency such Lender, such Issuer or the Agent (as the case may be) may
in accordance with normal, reasonable banking procedures purchase the specified currency with such
other currency. If the amount of the specified currency so purchased is less than the sum
originally due to such Lender, such Issuer or the Agent, as the case may be, in the specified
currency, the Borrower agrees, to the fullest extent that it may effectively do so, as a separate
obligation and notwithstanding any such judgment, to indemnify such Lender, such Issuer or the
Agent, as the case may be, against such loss, and if the amount of the specified currency so
purchased exceeds (a) the sum originally due to any Lender, any Issuer or the Agent, as the case
may be, in the specified currency and (b) any amounts shared with other Lenders as a result of
allocations of such excess as a disproportionate payment to such Lender under Section 11.2, such
Lender, such Issuer or the Agent, as the case may be, agrees to remit such excess to the Borrower.

15.5 USA PATRIOT Act. Each Lender hereby notifies the Borrower that pursuant to the
requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26,
2001)), it is required to obtain, verify and record information that identifies the Borrower, which
information includes the name and address of the Borrower and other information that will allow
such Lender to identify the Borrower in accordance with said Act.

15.6 Waiver of Immunity. To the extent that the Borrower or any Guarantor may be or become
entitled to claim for itself or its Property any immunity on the ground of sovereignty or the like
from suit, court jurisdiction, attachment prior to judgment, attachment in aid of execution of a
judgment or execution of a judgment, and to the extent that in any such jurisdiction there may be
attributed such an immunity (whether or not claimed), the Borrower and each Guarantor hereby
irrevocably agrees not to claim and hereby irrevocably waives such immunity with respect to its
obligations under the Loan Documents.

PRICING SCHEDULE

The Applicable Margin and Applicable Fee Rate shall be determined in accordance with the
following table, so long as the Loans are rated by Moody’s and S&P, based upon the ratings by
Moody’s and S&P, respectively, applicable on such date to the Loans:

	 	BB-/Ba3	 		2.500	%	 		0.500	%	 		2.500	%	 		1.875	%	 		0.500	%

For purposes of the foregoing, (a) if either Moody’s or S&P (but not both) shall have in
effect a rating for the Loans, then the level shall be based upon that rating; (b) if the ratings
established or deemed to have been established by Moody’s and S&P for the Loans, as the case may
be, shall fall within different Levels, the Applicable Margin and Applicable Fee Rate shall be
based on the higher of the two ratings unless one of the two ratings is two or more Levels lower
than the other, in which case the Applicable Margin and Applicable Fee Rate shall be determined by
reference to the Level next above that of the lower of the two ratings; and (c) if the ratings
established or deemed to have been established by Moody’s or S&P for the Loans shall be changed
(other than as a result of a change in the rating system of Moody’s or S&P), such change shall be
effective as of the date on which it is first announced or published by the applicable rating
agency or, in the absence of such announcement or publication, on the effective date of such rating
as determined by the Agent. Each change in the Applicable Margin and Applicable Fee Rate shall
apply during the period commencing on the effective date of such change and ending on the date
immediately preceding the effective date of the next such change. If the rating system of Moody’s
or S&P shall change, or if both such rating agencies shall cease to be in the business of rating
corporate debt obligations, the Borrower and the Lenders shall negotiate in good faith to amend
this definition to reflect such changed rating system or the unavailability of ratings from such
rating agencies and, pending the effectiveness of any such amendment, the Applicable Margin and
Applicable Fee Rate shall be determined by reference to the rating most recently in effect prior to
such change or cessation.

If neither Moody’s nor S&P shall have in effect a rating for the Loans, the Applicable Margin
and Applicable Fee Rate shall be determined in accordance with the following table, based upon the
Leverage Ratio as of the then-most recently delivered financial statements of the Borrower and its
Subsidiaries referred to in Section 6.1:

1. PRELIMINARY STATEMENT. The Assignor is a party to a Credit Agreement (which, as it
may be amended, modified, renewed or extended from time to time is herein called the “Credit
Agreement”) described in Item 1 of Schedule 1 attached hereto (“Schedule 1”).
Capitalized terms used herein and not otherwise defined herein shall have the meanings attributed
to them in the Credit Agreement.

2. ASSIGNMENT AND ASSUMPTION. The Assignor hereby sells and assigns to the Assignee,
and the Assignee hereby purchases and assumes from the Assignor, an interest in and to the
Assignor’s rights and obligations under the Credit Agreement and the other Loan Documents, such
that after giving effect to such assignment the Assignee shall have purchased pursuant to this
Assignment Agreement the percentage interest specified in Item 3 of Schedule 1 of all
outstanding rights and obligations under the Credit Agreement and the other Loan Documents relating
to the facilities listed in Item 3 of Schedule 1. The aggregate Commitment (or Loans, if
the applicable Commitment has been terminated) purchased by the Assignee hereunder is set forth in
Item 4 of Schedule 1.

3. EFFECTIVE DATE. The effective date of this Assignment Agreement (the
“Effective Date”) shall be the later of the date specified in Item 5 of Schedule 1
or two Business Days (or such shorter period agreed to by the Agent) after this Assignment
Agreement, together with any consents required under the Credit Agreement, are delivered to the
Agent. In no event will the Effective Date occur if (i) the payments required to be made by the
Assignee to the Assignor on the Effective Date are not made on the proposed Effective Date and (ii)
the payment of the recordation fee, described in Section 5 of this Assignment Agreement, is not
made to the Agent on or before the Effective Date. If the Assignee is not incorporated under the
laws of the United States of America or a state thereof, the Effective Date will not occur unless
the Assignee delivers to the Borrower and the Agent concurrently with the Effective Date two duly
completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI (or replacement or
successor forms, as the case may be), certifying in either case that the Assignee is entitled to
receive payments under the Loan Documents without deduction or withholding of any United States
federal income taxes.

4. PAYMENT OBLIGATIONS. In consideration for the sale and assignment of Outstanding
Credit Exposure hereunder, the Assignee shall pay the Assignor, on the Effective Date, the amount
agreed to by the Assignor and the Assignee. On and after the Effective Date, the Assignee shall be
entitled to receive from the Agent all payments of principal, interest, Reimbursement Obligations
and fees with respect to the interest assigned hereby. The Assignee will promptly remit to the
Assignor any interest on Credit Extensions and fees received from the Agent which relate to the
portion of the Commitment or Outstanding Credit Exposure assigned to the Assignee hereunder for
periods prior to the Effective Date and not previously paid by the Assignee to the Assignor. In
the event that either party hereto receives any payment to which the other party hereto is entitled
under this Assignment Agreement, then the party receiving such amount shall promptly remit it to
the other party hereto.

5. RECORDATION FEE. The Assignor and Assignee each agree to pay one-half of the
recordation fee required to be paid to the Agent in connection with this Assignment Agreement
unless otherwise specified in Item 6 of Schedule 1.

6. REPRESENTATIONS OF THE ASSIGNOR; LIMITATIONS ON THE ASSIGNOR’S LIABILITY. The

CONSENT TO SUB-SUBLEASE

This Consent to Sub-Sublease (“Agreement”) is made this 31st day of March, 2005,
by and among BETHESDA PLACE II LIMITED PARTNERSHIP (“Landlord”), a Maryland limited partnership,
INFORMAX, INC. (“Informax”), a Delaware corporation, and FIRST POTOMAC REALTY TRUST (“First
Potomac”), a Maryland real estate investment trust.

RECITALS

A. Landlord and Power Services Company, formerly known as PG&E National Energy Group Company,
formerly known as PG&E Generating Company (“PGE”), as successor-in-interest to U.S. Generating
Company, entered into a certain Office Lease Agreement dated June 25, 1998, whereunder Landlord
leased unto PGE the first (1st) through eleventh (11th) floors of the
building (the “Building”) known by street address as 7600 Wisconsin Avenue, Bethesda, Maryland.

B. By Sublease dated September 21, 2000 as amended by First Amendment to Sublease dated April
29, 2003 (collectively, the “Sublease”), PGE subleased to Informax approximately 18,095 rentable
square feet of space on the eleventh floor of the Building (such 18,095 rentable square foot space
being referred to herein as the “Premises”); and

C. PGE has assigned its interest under the Sublease to Landlord.

D. Informax has requested Landlord’s consent to the sub-sub letting by Informax to First
Potomac of the Premises.

C. Landlord is willing to consent to the sub-subletting of the Premises by Informax to First
Potomac, subject to all of the terms and provisions contained in this Agreement.

ACCORDINGLY, in consideration of the mutual covenants herein contained, the parties agree as
follows:

1. Landlord hereby consents to the sub-subletting of the Premises by Informax to First
Potomac pursuant to the agreement of the Sub-Sublease (the “Sub-Sublease”) annexed hereto as
Exhibit A but subject to the terms and provisions of this Agreement.

2. This consent shall not be deemed a consent to the assignment of the Sub-Sublease, the
further sub-subletting of the Premises, or the alteration of the Premises. The Sub-Sublease may not
be assigned, modified, amended, or extended and, except as set forth in the Sub-Sublease, the
Premises may not be altered or further sub-sublet in whole or in part without the prior written
consent of Landlord in each instance. Notwithstanding the preceding, Landlord acknowledges that the
leasehold improvements described on Exhibit B attached hereto as a part hereof (‘Initial
Leasehold Improvements”) may be made to the 11th Floor Premises by First Potomac and
that neither First Potomac nor InforMax shall be required to remove such alterations at the end of
the Term. The Initial Leasehold Improvements consist of two phases: Phase 1 will be completed at
the outset of the Term and Phase II will be completed at a later

1

date. Should InforMax or Landlord elect, at the time of consenting to alterations or
additions to be made by First Potomac on the 11th Floor Premises other than the Initial
Leasehold Improvements (‘Subsequent Alterations ”), that the Subsequent Alterations be removed on
the expiration of the Term, First Potomac agrees that InforMax or Landlord shall have the right to
cause same to be removed at First Potomac’s sole cost and expense; provided, however, that so long
as the Subsequent Alterations are consistent in all material respects with the tenor, scope, and
nature of the Initial Leasehold Improvements, neither Landlord nor InforMax shall have the right
to require First Potomac to remove such Subsequent Alterations on the expiration of the Term.
First Potomac agrees to reimburse InforMax or Landlord as Additional Rent for the cost and expense
of such removal and repairing any damage resulting therefrom.

3. This consent shall not be construed to waive, modify, amend, or affect (a) any of the
terms or provisions of the Lease or Sublease, (b) any of Informax’s obligations under the
Sublease, or (c) any rights or remedies of Landlord under the Lease or Sublease. The terms and
provisions of the Lease and Sublease shall continue to apply to the Premises and their occupants,
as if the Sub-Sub lease had not been made.

4. This consent shall not be deemed to enlarge or increase any of Landlord’s obligations
under the Lease or Informax’s rights under the Sublease or to waive, release, or discharge any
existing or future breach, default, or liability of Informax under the Sublease. Informax shall
remain liable and responsible for the full performance and observance of all of the terms and
provisions of the Sublease on Informax’s part to be observed or performed. If Informax shall
default in the payment of any rent under the Sublease, Landlord may collect any rents due or
accruing from First Potomac and apply the net amounts collected to the rents reserved under the
Sublease, but the receipt by Landlord of such amount from First Potomac shall not be deemed to
release Informax from its obligations or liability under the Sublease or to constitute Landlord’s
acceptance of First Potomac as a direct sub-subtenant.

5. The Sub-Sublease is and shall be at all times subject and subordinate to the Lease and the
Sublease and to all matters to which the Lease and the Sublease is subject and subordinate. The
Sub-Sublease also is and shall be subject to all of the terms, covenants, agreements, provisions,
and conditions of the Lease and the Sublease. In any conflict between the provisions of the Lease
or Sublease and the provisions of the Sub-Sublease, the provisions of the Lease or Sublease shall
prevail. Notwithstanding the preceding, if Landlord shall fail or refuse to comply with any of the
respective provisions of the Lease or Sublease, Landlord and Informax acknowledge and agree that
First Potomac may communicate directly with Landlord and/or its management agent with respect to
day-to-day matters within the scope of services provided by Landlord to, and for use and occupancy
of, the 11th Floor Premises under the terms of the Lease. First Potomac also shall have
the right to enforce directly Landlord’s obligations under the Lease.

6. Landlord makes no representation or warranty concerning the Lease, the Sublease, the
Sub-Sublease, the Premises, the Building or any matter or thing related to them. This Agreement
shall not constitute Landlord’s approval or ratification of any of the provisions of the
Sub-Sublease and Landlord shall not be bound or estopped by any of the provisions of the
Sub-Sublease in any way. Notwithstanding the foregoing sentence, Landlord hereby agrees as

2

follows:

6.1 First Potomac shall have the right to display its name and, subject to Landlord’s
approval, the names often (10) of its officers, on the Building directory in the size and style or
lettering used by Informax First Potomac may display its name and logo on the corridor wall
adjacent to the 11th Floor Premises, subject to the approval of Landlord, which
approval shall not be unreasonably withheld or delayed and at First Potomac’s expense. At the
expiration or earlier termination of the Term, First Potomac shall remove such name and logo at
its sole cost and expense and in a good and workmanlike manner.

6.2 Should First Potomac require heating or cooling services beyond the Normal Business Hours
for the Building stipulated in Section 1B(23) of the Lease, First Potomac may request that
Landlord furnish such additional service at the then-prevailing hourly rate, by written or
telephonic notice delivered to Landlord at the office of the Building during Normal Business
Hours, at least two (2) hours in advance of the beginning of the period of time for which such
usage is requested.

7. Upon the expiration or any earlier termination of the term of the Sublease, or in case
Landlord accepts surrender of the Sublease by Informax, except as provided in the next sentence,
the Sub-Sublease and its term shall expire and come to an end as of the effective date of such
expiration, termination, or surrender and First Potomac shall vacate the Premises on or before such
date. If the Sublease shall expire or terminate during the term of the Sub-Sublease for any reason
other than condemnation or destruction by fire or other cause, or if Informax shall surrender the
Sublease to Landlord during the term of the Sub-Sublease, either Landlord or First Potomac, in its
sole discretion, upon written notice given to Informax and Landlord or First Potomac, as
applicable, on or before the effective date of such expiration, termination or surrender, without
any additional or further agreement of any kind on the part of Landlord or First Potomac, may elect
to continue the Sub-Sublease as a direct sublease between Landlord and First Potomac (provided that
the terms and provisions of the Sublease shall be deemed incorporated in the Sub-Sublease to the
same extent as if the Sublease had not expired or terminated). In that event, First Potomac shall
attorn to Landlord and Landlord and First Potomac shall have the same rights, obligations and
remedies under the Sub-Sublease as Informax and First Potomac, respectively, had thereunder prior
to such effective date, except that Landlord shall not be (1) liable for any act, omission, or
default of Informax under the Sub-Sublease or for the return of all or any part of any security
deposit not actually received by Landlord (and First Potomac shall have no claim against any
security deposited under the Sublease), or (2) subject to any offsets, claims, or defenses that
First Potomac had or might have against Informax, or (3) bound by any rent or additional rent or
other payment paid by First Potomac to Informax in advance, or (4) bound by any modification,
amendment, or abridgment of the Sub-Sublease made without Landlord’s prior written consent. Upon
expiration of the Sub-Sublease pursuant to the provisions of the first sentence of this
Paragraph 7, if First Potomac shall fail to vacate the Premises as provided in the
Sub-Sublease, Landlord shall have against First Potomac all of the rights and remedies available
against Informax under the Sublease and Lease as well as the rights and remedies available
generally to a Landlord against a tenant holding over after the expiration of a term.

3

8. Both Informax and First Potomac at all times shall be liable for all bills rendered
by Landlord pursuant to the Lease or Sublease for charges incurred by or imposed upon First
Potomac for services rendered and materials supplied to the Premises.

9. Informax represents that, as of the date hereof and to the best knowledge of Troy Gardner,
Director, Global Real Estate and Equipment, that all of the obligations of Landlord under the
Sublease have been complied with and performed by Landlord and that Landlord is not in default
under the Sublease. Mr. Gardner shall have no personal liability under this Agreement.

10. Informax and First Potomac each severally represents and warrants to Landlord that the
information supplied to Landlord by each of Informax and First Potomac in connection with
obtaining this Consent to Sub-Sublease (including, but not limited to, all summaries, financial
statements, notices, and other documents) is true and complete in all material respects and that
no consideration has been or will be paid by First Potomac for or in connection with the
Sub-Sublease or the sale of any furniture, furnishings, fixtures, or improvements in the Premises
that has not been disclosed in the Sub-Sublease. Also, Informax and First Potomac each severally
represents and warrants to Landlord that Exhibit A is a complete and correct copy of the
Sub-Sublease and that there are no other agreements between them relating to the Sub-Sublease, or
the use or occupancy of the Premises or the furniture, furnishings, fixtures, or improvements
therein. The representations and warranties contained in this Paragraph 10 shall be deemed
incorporated in the Sublease and the material inaccuracy of any of such representations and
warranties shall constitute a default under the Sublease entitling Landlord to exercise any or all
the remedies for default provided in the Sublease or otherwise available at law or in equity.

11. Any notice, demand, consent, approval, disapproval, or statement (collectively, “Notices”)
given under the Sub-Sublease or under this Agreement shall be given in accordance with the terms of
the Lease, except that such Notices, if given to Informax or First Potomac shall be addressed to
such parties at the addresses set forth in Section 17 of the Sub-Sublease. Each party to this
Agreement shall have the right to designate a different address by delivering at least ten (10)
days prior written notice to the other parties to this Agreement.

12. Informax and First Potomac agree that Landlord shall not be responsible for the
payment of any commissions or fees in connection with the Sub-Sublease and they each jointly and
severally agree to indemnify and hold Landlord harmless from and against any claims, liability,
losses or expenses, including reasonable attorneys’ fees, incurred by Landlord in connection with
any claims for commissions or fees by any broker or agent in connection with the Sub-Sublease.

4

13. This Agreement shall not be effective until executed by each of Landlord, Informax
and First Potomac. This Agreement may be executed in several counterparts, all of which shall
constitute one and the same document. This Agreement may be executed by facsimile and facsimile
signature pages will be fully binding on each of Landlord, Informax and First Potomac.

IN WITNESS WHEREOF, this Agreement has been executed as of the day and year first written
above.

10

the Term of this Sub-Sublease, assumes all of the terms, covenants, conditions and
agreements contained in the Lease and the InforMax Sublease with respect to the 11th
Floor Premises, to be performed by InforMax thereunder. The parties hereto agree that subject to
the provisions of this Sub-Sublease, wherever the words “Premises” or words of similar import
appear in the Lease and the InforMax Sublease, the same shall be deemed to mean the 11th
Floor Premises and wherever the words “Landlord” (or “Sublandlord”) and “Tenant” (or “Subtenant”)
appear in the Lease or the InforMax Sublease, the words shall be deemed to refer to InforMax and
First Potomac respectively, so that, subject to the provisions of this Sub-Sublease and with
respect only to the 11th Floor Premises, InforMax shall have the rights and powers of
the Landlord under the Lease and Sublandlord under the InforMax Sublease, and First Potomac shall
have and does hereby agree to be bound by and accept all the rights, powers, duties and obligations
of the Tenant under the Lease and Subtenant under the InforMax Sublease; provided, however, that
notwithstanding the foregoing, InforMax shall have no obligation to perform or furnish any of the
work, services, repairs, or maintenance undertaken to be made by Landlord under the Lease or
Sublandlord under the InforMax Sublease, or any other term, covenant, or condition required to be
performed by Landlord under the Lease or Sublandlord under the InforMax Sublease. First Potomac
covenants and agrees that it shall do nothing that shall have the effect of creating a breach of
any of the terms, covenants, and conditions of the Lease or the InforMax Sublease. If Landlord
shall fail or refuse to comply with any of the respective provisions of the Lease or the InforMax
Sublease (respectively), InforMax shall have no liability on account of any such failure or
refusal, but Landlord and InforMax acknowledge and agree that First Potomac shall have the right to
enforce directly Landlord’s obligations under the Lease. First Potomac may communicate directly
with Landlord and/or its management agent with respect to day-to-day matters within the scope of
services provided by Landlord to, and for use and occupancy of, the 11th Floor Premises
under the terms of the Lease. InforMax hereby agrees to cooperate with and execute, all at First
Potomac’s expense, all instruments and supply information reasonably required by First Potomac to
enforce such compliance (including the assertion of such rights against the Landlord under the
Lease). First Potomac hereby agrees to indemnify and hold InforMax harmless of and from any and all
damages, liabilities, obligations, costs, claims, losses, demands, and expenses, including
reasonable attorneys’ fees, which may be incurred by InforMax in or as a result of such cooperation
and execution, unless caused by the negligence or willful misconduct of InforMax. In amplification
and not in limitation of the foregoing and without any allowance to First Potomac or other
reduction or adjustment of Rent, InforMax shall not be responsible for furnishing electrical,
elevator, heating, air conditioning, cleaning, window washing, or other services, nor for any

Potomac agrees that InforMax shall not have any duty or responsibility with respect to obtaining
the consent or approval of Landlord when the same is required under the terms of the Lease or the
InforMax Sublease, other than the transmission by InforMax to Landlord of First Potomac’s request

without being under any obligation to do so and without thereby waiving such default, may remedy
such default for the account and at the expense of First Potomac upon prior notice. If

connection therewith, such sums paid or obligations incurred shall be deemed to be Additional Rent
hereunder and shall be paid to InforMax by First Potomac on demand.

(ii) InforMax shall not do or suffer or permit anything to be done that would cause the Lease
or InforMax Sublease to be terminated or forfeited by virtue of any rights of termination or

any applicable cure period in the performance of any of its obligations under this Sub-Sublease,
under the InforMax Sublease, or under the Lease, First Potomac without being under any obligation
to do so and without thereby waiving such default, may remedy such default for the account and at
the expense of InforMax upon at least seven (7) days’ prior written notice. If First Potomac makes
any expenditures or incurs any obligation for the payment of money in connection therewith, such
sums paid or obligations incurred (all of which sums shall be reasonable, direct out of pocket
expenses paid by First Potomac) shall be paid to First Potomac by InforMax on demand.

9. Utilities.

9.1 Overtime Heating and Air Conditioning. Should First Potomac require heating or
cooling services beyond the Normal Business Hours for the Building stipulated in Section 1B(23) of
the Lease, First Potomac may request that Landlord furnish such additional service at the
then-prevailing hourly rate, by written or telephonic notice delivered to Landlord at the office

of the period of time for which such usage is requested. InforMax shall have no liability or
responsibility for furnishing such heating or cooling services beyond the Normal Business Hours
for the Building.

Premises, and portion thereof, or any electrical equipment or machinery therein, is consuming or
will consume electricity in excess of 1.5 watts per square foot for lighting (exclusive of the
electric power needed for the Building MEP systems) and/or 5 watts per square foot for receptacles
(exclusive of the electric power needed for the Building MEP systems), or (b) that the
11th Floor Premises, and portion thereof, or any electrical equipment or machinery
therein, is consuming or will consume electricity for significantly more hours per week than is
standard for normal office use, then InforMax may require that the 11th Floor Premises
or such portion thereof or such equipment or machinery therein be separately metered or submetered
for electricity consumption. The cost of any such meters and of installation, maintenance and
repair thereof shall be paid by First Potomac as Additional Rent. First Potomac shall pay InforMax
or Landlord (or the utility company, if direct service is provided by the utility company),
promptly upon demand therefor, for all such electricity consumption as shown by such meters, at
the rates charged for such service by the local public utility company.

10. Assignment of Sub-Sublease; Sub-Sub-Subletting.

10.1 First Potomac shall not assign (except to the surviving entity of a transaction in which
First Potomac or First Potomac Realty Investment Limited Partnership is a party as long as such
transaction is for a good business purpose and not principally for the purpose of transferring this
Sub-Sublease, the net worth (as determined in accordance with generally accepted accounting
principles (“GAAP”)) of the surviving entity is not less than the net worth (as determined in
accordance with GAAP) of First Potomac as of the date of First Potomac’s most current quarterly or
annual financial statements, and such surviving entity shall agree in writing to assume all of the
terms, covenants and conditions of this Sub-Sublease arising after the effective date of the
assignment), mortgage or encumber this Sub-Sublease, nor sub-sub-sublet, nor suffer or permit the
11th Floor Premises or any part thereof to be used by others (any of which events is
hereinafter and in the Lease referred to as a “Transfer”), except with the prior written consent of
InforMax, which consent shall not be unreasonably withheld or delayed, except as otherwise set
forth in Section 10.2. Any attempted Transfer in violation of this provision shall be void. In no
event shall any Transfer relieve First Potomac of its liability and responsibility to InforMax
under this Sub-Sublease or Landlord under either the InforMax Sublease or under the Lease (as the
case may be) in the absence of any express written agreement with InforMax or Landlord, as the case
may be, to that effect.

10.2 First Potomac shall pay to InforMax monthly fifty percent (50%) of any Net Profits (as
defined below) received by First Potomac in connection with a Transfer. “Net Profits” means the
excess of the rent and/or all other sums collected by First Potomac under or in connection with
such sub-sub-sublease over and above the Rent payable by First Potomac to InforMax under this
Sub-Sublease for the space covered by such sub-sub-sublease (which shall be the pro rata portion
of the total Rent payable hereunder) and the direct, out of pocket costs incurred by First Potomac
in performing alterations or leasehold improvements for the sub-sub-subtenant and the leasing
commissions paid, and rental abatement granted, by First Potomac in connection with such
sub-sub-sublease.

11. Alterations to 11th Floor Premises. First Potomac covenants at all
times during the Term not to make any structural alterations or any material non-structural
alterations or additions to the 11th Floor Premises of any nature whatsoever without the
prior written consent of InforMax and Landlord, which consent shall not be unreasonably withheld,
conditioned, or delayed for nonstructural, interior alterations. If First Potomac obtains
InforMax’s and Landlord’s consent and all necessary governmental approvals and permits, First
Potomac shall have the right to make such alterations at First Potomac’s sole expense. All
alterations and additions made by First Potomac to the 11th Floor Premises shall remain
upon the 11th Floor Premises and be surrendered with the 11th Floor Premises
at the expiration of the Term without disturbance, molestation or injury, unless otherwise
specified by InforMax or Landlord. Landlord acknowledges that the leasehold improvements described
on Exhibit C attached hereto as a part hereof (“Initial Leasehold Improvements”) may be
made to the 11th Floor Premises by First Potomac and that neither First Potomac nor
InforMax shall be required to remove such alterations

14

at the end of the Term. The Initial Leasehold Improvements consist of two phases: Phase 1
will be completed at the outset of the Term and Phase II will be completed at a later date. Should
InforMax or Landlord elect, at the time of consenting to alterations or additions to be made by
First Potomac on the 11th Floor Premises other than the Initial Leasehold Improvements
(“Subsequent Alterations”), that the Subsequent Alterations be removed on the expiration of the
Term, First Potomac agrees that InforMax or Landlord shall have the right to cause same to be
removed at First Potomac’s sole cost and expense; provided, however, that so long as the
Subsequent Alterations are consistent in all material respects with the tenor, scope, and nature
of the Initial Leasehold Improvements, neither Landlord nor InforMax shall have the right to
require First Potomac to remove such Subsequent Alterations on the expiration of the Term. First
Potomac agrees to reimburse InforMax or Landlord as Additional Rent for the cost and expense of
such removal and repairing any damage resulting therefrom.

12. Signage.

12.1 Directory and Suite Entrance Signs. First Potomac shall have the right to
display its name and, subject to Landlord’s approval, the names often (10) of its officers, on the
Building directory in the size and style or lettering used by InforMax. First Potomac may display
its name and logo on the corridor wall adjacent to the 11th Floor Premises, subject to
the approval of Landlord, which approval shall not be unreasonably withheld or delayed and at
First Potomac’s expense. At the expiration or earlier termination of the Term, First Potomac shall
remove such name and logo at its sole cost and expense and in a good and workmanlike manner.

12.2 Consent Required. No sign, advertisement, or notice shall be inscribed, painted,
affixed, or displayed on any part of the outside or the inside of the Building, or inside of the
11th Floor Premises where it may be visible from outside or from the public areas of
the Building, except with the prior written consent of InforMax and Landlord, which consent may be
granted or withheld in their sole and absolute subjective discretion, and then only in such
location, number, size, color, and style as is authorized by InforMax and Landlord. If any such
sign, advertisement, or notice is exhibited without first obtaining written consent from InforMax
and Landlord, InforMax shall have the right to remove same, and First Potomac shall be liable for
any expenses (all of which shall be deemed Additional Rent) incurred by InforMax in connection
with such removal.

13. Indemnity. Except for the grossly negligent or willful acts or omissions of
Landlord and its and their respective members, principals, beneficiaries, partners, officers,
directors, employees, Mortgagee(s), and agents, and the respective principals and members of any
such agents (collectively, the “Landlord Related Parties"), or of InforMax, and its affiliates,
subsidiaries, members, principals, beneficiaries, partners, officers, directors, employees, and
agents, and the respective principals and members of any such agents (collectively, the “InforMax
Related Parties"), First Potomac shall indemnify, defend, and hold Landlord, the Landlord Related
Parties, InforMax and the InforMax Related Parties harmless against and from all liabilities,
obligations, damages,

limitation, reasonable attorneys’ fees and other professional fees (if and to the extent permitted
by law), which may be imposed on, incurred by, or asserted against Landlord, any of the Landlord
Related Parties, InforMax or any of the InforMax Related Parties that (a) arise from or in
connection with the possession, occupancy, management, repair, maintenance, or control of the
11th Floor Premises, or any portion thereof, by First Potomac or any party claiming by,
through or under First Potomac, or (b) arise from or in connection with any act or omission by
First Potomac or any party claiming by, through or under First Potomac in the Limited Common Areas
of the Building (defined, for purposes of this Sub-Sublease, the InforMax Sublease, and the Lease,
notwithstanding anything to the contrary in the Lease or the InforMax Sublease, as those areas of
the Building provided for the common use or benefit of InforMax, First Potomac, the other tenants
of the Building and Landlord, such as corridors, elevator foyers, restrooms, lobby areas, loading
docks and other similar facilities) including, to the extent applicable under this paragraph, all
such Claims resulting by reason of any injury or death to persons or damage to property, or (c)
arise from or in connection with any act or omission of First Potomac or any of its transferees,
agents, servants, contractors, employees, customers, licensees or invitees, or (d) result from any
failure on the part of First Potomac to perform or comply with any of the covenants, agreements,
terms, or conditions contained in the Lease, the InforMax Sublease, or this Sub-Sublease with
which First Potomac must comply or perform, or (e) arise from injury or death to persons or damage
to property sustained in the 11th Floor Premises or any other space leased to First
Potomac in the Building. In case any action or proceeding is brought against Landlord, any of the
Landlord Related Parties, InforMax or any of the InforMax Related Parties by reason of any of the
foregoing, First Potomac shall, at First Potomac’s sole cost and expense, resist and defend such
action or proceeding with counsel approved by Landlord and InforMax, or at Landlord’s and
InforMax’s option, reimburse Landlord and InforMax for the cost of any counsel directly retained
by Landlord and InforMax to defend and resist such action or proceeding.

14. First Potomac’s Insurance. At all times commencing on the date First Potomac or
its agents, employees, or contractors enter the 11th Floor Premises for any purpose,
First Potomac shall carry and maintain, at its sole cost and expense:

14.1 Commercial General Liability Insurance applicable to the 11th Floor Premises,
providing, on an occurrence basis, a minimum combined single limit of Two Million Dollars
($2,000,000), with a contractual liability endorsement covering First Potomac’s indemnity
obligations under this Sub-Sublease, the InforMax Sublease, and the Lease.

14.2 All Risk of Physical Loss Insurance written at replacement cost value and with a
replacement cost endorsement covering all of First Potomac’s property hi the 11th Floor
Premises.

16

14.3 Workers’ Compensation Insurance as required by Maryland in amounts as may be
required by applicable statute, and Employers’ Liability Coverage of One Million Dollars
($1,000,000) per occurrence.

14.4 Whenever Landlord requires InforMax to obtain additional insurance coverage or different
types of insurance pursuant to the Lease or the InforMax Sublease, First Potomac shall, on
request, obtain such insurance at First Potomac’s expense and provide InforMax with evidence
thereof.

The requirements of Section 16C of the Lease shall apply to all insurance that First Potomac is
required to maintain pursuant to the terms of this Sub-Sublease.

15. Eminent Domain, Loss by Casualty. In the event of any taking by eminent domain or
damage by fire or other casualty to the 11th Floor Premises thereby rendering the
11th Floor Premises wholly or in part untenantable, First Potomac shall acquiesce in
and be bound by any action taken by or agreement entered into between Landlord and InforMax with
respect thereto; provided, however, in the event InforMax is not required to pay all or any
portion of its Rent under the InforMax Sublease pursuant to such agreement, First Potomac shall
not be required to pay all or a proportionate amount of its Rent under this Sub-Sublease.

16. Default.

16.1 Events of Default. In addition to the events of default set forth in Section 22
of the Lease (which are hereinafter incorporated by reference), the following event shall be
deemed to be events of default (“Events of Default”) under this Sub-Sublease:

(i) A Transfer in violation of Section 10;

(ii) First Potomac’s abandonment of the 11th Floor Premises for more than thirty
(30) consecutive days; or

(iii) InforMax’s failure or refusal to comply with any of its obligations under the InforMax
Sublease or this Sub-Sublease and such failure or refusal is not cured within five (5) days with
respect to a monetary default, and ten (10) business days, with respect to a non-monetary default,
of its receipt of notice of such default from First Potomac and such failure or refusal is not
attributable, in whole or in part, to any breach or default by First Potomac of its obligations
under this Sub-Sublease; provided, however, that with respect to non-monetary defaults, if
InforMax initiates curative action within such ten (10) business day period, InforMax shall have
such additional time as may be necessary to cure such failure as long as InforMax is diligently
pursuing the cure to completion.

17

16.2 Remedies.

(i) If this Sub-Sublease or First Potomac’s right to possession of the 11th Floor
Premises is terminated by InforMax because of an event of default by First Potomac, InforMax shall
have all of the remedies set forth in Section 23 of the Lease for a defaulting tenant.

(ii) If this Sub-Sublease is terminated by First Potomac because of an Event of Default by
InforMax under Section 16.1(iii) above (which termination shall be made by First Potomac, if at
all, within ninety (90) days after the date of the Event of Default), InforMax shall immediately
return the Security Deposit to First Potomac and First Potomac shall have no further obligations
or liabilities under this Sub-Sublease.

17. Notice and Demands. All notices or demands under this Sub-Sublease shall be in

All notices hereunder shall be effective when delivered in person or by overnight courier service,
as indicated on the receipt obtained by the messenger or overnight delivery service, or three (3)
business days after mailing, as the case may be.

18. Surrender of 11th Floor Premises. On the expiration or
earlier termination of the Term, First Potomac covenants to quit and surrender to InforMax or

18

Landlord, as the case may be, the 11th Floor Premises, broom clean, in
good order and condition, ordinary wear and tear damage by fire or other casualty excepted, and at
First Potomac’s expense to remove all property of First Potomac. Any property not so removed shall
be deemed to have been abandoned by First Potomac and may be retained or disposed of at First
Potomac’s expense by InforMax or Landlord, as they may desire.

19. Parking. InforMax shall make available to First Potomac parking in the Building
parking garage in the same ratio as granted to it by Landlord under the InforMax Sublease. As of
the date of this Sub-Sublease, the parking ratio is equal to two (2) parking spaces per one
thousand (1,000) rentable square feet of floor space in the 11th Floor Premises;
provided, however, that if First Potomac does not commence using all such parking spaces within
ninety (90) days of the Rent Commencement Date, or ceases using all such parking spaces at any time
thereafter, First Potomac shall thereafter have the right to use the unused parking spaces
allocated to First Potomac only to the extent there are then unused parking spaces in the Building
parking garage. For each month during the Term, First Potomac shall pay to InforMax, as Additional
Rent for the use of such parking spaces, an amount equal to the product obtained by multiplying:
(a) the number of parking spaces utilized by First Potomac in this Section, by (b) the market rent
for each such space, as determined from time to time by Landlord, InforMax, and/or the garage
operator. No specific parking spaces shall be designated for use by First Potomac. First Potomac
acknowledges that Landlord has the right to institute either a valet or self-parking system.

20. Brokerage Fees. The parties hereto represent and warrant to each other that they
have not dealt with any broker other than Newmark of Washington, D.C. LLC (“Newmark”). InforMax
shall pay Newmark a brokerage commission pursuant to a separate agreement between InforMax and
Newmark in connection with this Sub-Sublease. Each party hereto agrees to indemnify, defend, and
hold the other party harmless against any claim, liability, or expense (including, but not limited
to, reasonable attorneys’ fees) for a commission by any broker, arising by reason of a breach by
the indemnifying party of the foregoing representation and warranty.

21. Authority to Execute Lease. Each of First Potomac and InforMax represents and
warrants that this Sub-Sublease has been duly authorized, executed, and delivered by and on behalf
of such party and constitutes the valid and binding agreement of such party in accordance with the
terms hereof.

22. Security Deposit. Simultaneously with the execution and delivery of this
Sub-Sublease, First Potomac will deposit with InforMax cash or a Letter of Credit (as defined
below) in an amount equal to Thirty-Nine Thousand Two Hundred Five and 83/100 Dollars ($39,205.83)
(“Security Deposit”) to secure, in part, First Potomac’s due performance and observance of the
obligations, conditions, or agreements of this Sub-Sublease. The Security Deposit, if in the form
of cash, will not bear interest while being held by InforMax hereunder. If an Event of Default by
First Potomac occurs under this Sub-Sublease, without prejudice to InforMax’s other remedies,
InforMax shall apply all or any portion of the Security Deposit to compensate InforMax (whether in
whole or in

19

part) for such Event of Default. If any portion of the Security Deposit is so applied and
the Event of Default is subsequently cured or waived, First Potomac will be obligated to deposit
with InforMax, within fifteen (15) days thereafter, the amount necessary to restore the balance of
the Security Deposit to its original amount. If any sale or transfer occurs of InforMax’s interest
in this Sub-Sublease, InforMax may transfer the Security Deposit to such purchaser or transferee,
in which event Tenant will look solely to the new sub-sublandlord for the return of the Security
Deposit and InforMax will thereupon be released from all liability to Tenant for the return of the
Security Deposit. The Security Deposit will not be transferable by Tenant to any assignee or
subtenant, but will be held and returned directly to Tenant.

In lieu of providing a cash Security Deposit, simultaneously with the execution and delivery
of this Sub-Sublease, First Potomac may deliver to InforMax an irrevocable and transferable letter
of credit (“Letter of Credit”) running in favor of InforMax, with the Letter of Credit securing
First Potomac’s obligations hereunder subject to the terms and conditions set forth in this
Section 22. The Letter of Credit shall be issued by a bank acceptable to InforMax in InforMax’s
sole but reasonable discretion and under the supervision of the banking commission of the State of
Maryland or the Federal Deposit Insurance Corporation. Such issuing bank shall have banking
offices at which the Letter of Credit may be drawn upon in the Washington, D.C. metropolitan area.
If the credit of the bank that originally issues the Letter of Credit becomes unacceptable to
InforMax in InforMax’s sole but reasonable discretion, First Potomac shall substitute another
Letter of Credit from a bank that is acceptable to InforMax in InforMax’s sole reasonable
discretion. The Letter of Credit shall be irrevocable for the period ending no less than one (1)
year after the date of issuance. First Potomac shall renew the Letter of Credit and maintain it
for the period ending five (5) days after the later of (a) the date of actual termination of this
Sub-Sublease, or (b) the date First Potomac shall have vacated and surrendered the entire Premises
to InforMax in accordance with the terms hereof and shall provide that it is automatically
renewable for the Term, unless released pursuant to the provisions of this Section or unless the
issuing bank delivers a notice of non-renewal no later than thirty (30) days before expiration. If
First Potomac fails to renew the Letter of Credit within ten (10) days of its expiration, InforMax
may draw on the existing Letter of Credit and maintain the funds as a non-interest-bearing deposit
to be returned to First Potomac on receipt by InforMax of a substitute Letter of Credit from First
Potomac. The form and terms of the Letter of Credit shall be reasonably acceptable to InforMax and
shall provide, among other things, in effect that:

(a) InforMax (“Beneficiary”) shall have the right to draw down an amount up to the then
current face amount of the Letter of Credit after an Event of Default by First Potomac on
presentation to the issuing bank of InforMax’s own declaration signed or purportedly signed by or
on its behalf reading as follows: (a) that the declarant is an officer (or general partner or sole
proprietor in the case of a general partnership or sole proprietorship, respectively, or member in
the case of a limited liability company) of the Beneficiary on behalf of the Beneficiary; (b) that
the declarant has authority to make the declaration on behalf of the Beneficiary; (c) that the
declaration is made pursuant to the terms of the Letter of Credit number      ; (d) that an

20

Event of Default has occurred under the terms of a sub-sublease made between Beneficiary
and First Potomac; (e) that the amount of the Event of Default is $     ; and (f) [or in
lieu of clauses (d) and (e)} that First Potomac under the terms of a sub-sublease made between
Beneficiary and First Potomac has failed to provide a substitute Letter of Credit.

(b) The Letter of Credit will be honored by the issuing bank without inquiry as to the
accuracy thereof and regardless of whether First Potomac disputes the content of such statement.

(c) In the event of a transfer of InforMax’s interest in the Premises, InforMax shall have
the right to transfer the Letter of Credit to the transferee, and it is agreed that the provisions
hereof shall apply to every transfer or assignment of the Letter of Credit to a new
sub-sublandlord. In the event of such a transfer, the provider of the Letter of Credit must be
ratified by InforMax by return of a transfer agreement.

(d) If, as a result of any such application of all or any part of the Letter of Credit, the
amount secured by the Letter of Credit shall be less than twenty-five percent (25%) of the
original amount of the Letter of Credit, First Potomac shall immediately provide InforMax with
cash or other immediately available funds, or an additional Letter of Credit that meets the
requirements of this Section, to cover the deficiency, or restore the amount available to be drawn
under the Letter of Credit to the amount required herein on written notice from InforMax to First
Potomac.

(e) First Potomac shall not assign or encumber the Letter of Credit or any part thereof and
that neither InforMax nor its successors or assigns will be bound by any such assignment,
encumbrance, attempted assignment, or attempted encumbrance.

(f) Without limiting the generality of the foregoing, if the Letter of Credit expires earlier
than as provided for herein, or the issuing bank notifies InforMax that it shall not renew the
Letter of Credit, InforMax will accept a renewal thereof or substitute Letter of Credit (such
renewal or substitute Letter of Credit to be in effect not later than thirty (30) days before the
expiration thereof), which renewal or substitute Letter of Credit shall be irrevocable and
automatically renewable, and issued by a bank meeting the requirements of this Section, for the
entire period provided for in this Section, on substantially the same terms as the expiring Letter
of Credit or such other terms as may be acceptable to InforMax. However, (i) if the Letter of
Credit is not timely renewed or a substitute Letter of Credit is not timely received, or (ii) if
First Potomac fails to maintain the Letter of Credit in the amount and terms set forth in this
Section, then, at least thirty (30) days before the expiration of the Letter of Credit, or
immediately on First Potomac’s failure to comply with every term of this Section, First Potomac
shall deposit with InforMax cash security in the amounts required by, and to be held subject to the
terms of this Section, failing which InforMax may present such Letter of Credit to the bank, in
accordance with the terms of this Section, and the entire sum secured thereby shall be paid to
InforMax as a substitute Security Deposit, to be held by InforMax in the manner provided for in
this Section.

21

23. Consent of Landlord. The written consent of Landlord to this Sub-Sublease
is required under the terms of the InforMax Sublease and the Lease, and neither party hereto shall
be bound hereby until such consent is fully executed and delivered among the parties. This
Sub-Sublease is contingent, in its entirety, upon InforMax’s obtaining Landlord’s consent to this
Sub-Sublease. If such consent has not been obtained within thirty (30) days after execution and
delivery of this Sub-Sublease by InforMax and First Potomac, then either party may terminate this
Sub-Sublease by written notice to the other given before such consent is obtained. In the event of
such termination, InforMax shall promptly return any Security Deposit and advance rental payment
theretofore paid by First Potomac, and the parties shall thereupon be relieved of any liability
hereunder. On the execution and delivery hereof, InforMax will promptly submit this Sub-Sublease
to Landlord for its consent. First Potomac shall promptly deliver to InforMax any information
reasonably requested by Landlord (in connection with its approval of this Sub-Sublease) for the
nature and operation of First Potomac’s business and/or the financial condition of First Potomac.

24. Quiet Enjoyment. So long as First Potomac shall observe and perform all of the
covenants and agreements binding on it hereunder and subject to the operation and effect of the
Informax Sublease and the Lease, First Potomac shall at all times during the Term hereof
peacefully and quietly have and enjoy possession of the 11th Floor Premises without
hindrance by InforMax and Landlord.

25. Miscellaneous.

25.1 No Offer. Submission of this instrument for examination shall not constitute a
reservation of or option for the 11th Floor Premises or in any manner bind InforMax and
no obligation on InforMax shall arise until this instrument is signed and delivered by InforMax
and First Potomac.

25.2 No Partnership. Nothing contained in this Sub-Sublease shall be deemed or
construed by the parties hereto or by any third party to create the relationship of principal and
agent, partnership, joint venturer, or any association between InforMax and First Potomac, it being
expressly understood and agreed that neither the method of computation of Base Rental nor any other
provisions contained in this Sub-Sublease nor any act of the parties hereto shall be deemed to
create any relationship between InforMax and First Potomac other than the relationship of landlord
and tenant.

25.3 Time of the Essence. Time is of the essence of this Sub-Sublease and of each
provision hereof.

25.4 Separability. The legal invalidity of any provision of this Sub-Sublease shall
not impair or affect in any manner the validity, enforceability, or effect of the rest of this
Sub-Sublease.

all of which shall constitute one and the same document.

between the parties hereto are merged in this Sub-Sublease, which alone fully and completely
expresses the agreement between InforMax and First Potomac.

25.7 Estoppel Certificate. Within fifteen (15) days after InforMax’s request, First
Potomac shall execute, acknowledge, and deliver to InforMax a written statement certifying: (a)

Sub-Sublease as requested by InforMax.

25.8 Governing Law. This Sub-Sublease and the rights and obligations of the parties
hereto shall be interpreted and enforced in accordance with Maryland law.

25.9 WAIVER OF JURY TRIAL. INFORMAX AND FIRST POTOMAC HEREBY WAIVE TRIAL BY JURY IN
ANY ACTION OR PROCEEDING TO WHICH IT MAY BE A PARTY ARISING OUT OF OR IN ANY WAY RELATED TO THIS
SUB-SUBLEASE. IT IS UNDERSTOOD THAT THIS WAIVER CONSTITUTES A WAIVER OF TRIAL BY JURY OF ALL
CLAIMS AGAINST ALL PARTIES TO SUCH ACTIONS OR PROCEEDINGS. THIS WAIVER IS KNOWINGLY, WILLINGLY,
