                        TERM LOAN AND SECURITY AGREEMENT

     This TERM LOAN AND SECURITY AGREEMENT (the "Agreement") dated June 14, 2005
by and among SILICON VALLEY BANK, a California-chartered bank, with its
principal place of business at 3003 Tasman Drive, Santa Clara, California 95054
("SVB"), as agent (the "Agent"), and the Lenders listed on Schedule 1.1 and
otherwise party hereto, including without limitation, SVB and Gold Hill Venture
Lending 03, L.P. ("Gold Hill") and NETEZZA CORPORATION, a Delaware corporation,
whose address is 200 Crossing Boulevard, Framingham, Massachusetts 01702
("Borrower") provides the terms on which Lenders shall extend credit to Borrower
and Borrower shall repay Lenders. The parties agree as follows:

1 ACCOUNTING AND OTHER TERMS

     Accounting terms not defined in this Agreement shall be construed following
GAAP. Calculations and determinations must be made following GAAP. The term
"financial statements" includes the notes and schedules attached hereto. The
terms "including" and "includes" always mean "including (or includes) without
limitation," in this or any Loan Document. Capitalized terms in this Agreement
shall have the meanings set forth in Article 13. All other terms contained in
this Agreement, unless otherwise indicated, shall have the meaning provided by
the Code, to the extent such terms are defined therein.

2 LOAN AND TERMS OF PAYMENT

     2.1 PROMISE TO PAY.

     Borrower hereby unconditionally promises to pay Lenders the unpaid
principal amount of all Credit Extensions and interest on the unpaid principal
amount of the Credit Extensions as and when due in accordance with this
Agreement.

          2.1.1 TERM LOAN FACILITY.

          (a) Availability. Subject to the terms and conditions of this
Agreement, Lenders agree, severally and not jointly, to lend to Borrower from
time to time prior to the Commitment Termination Date, advances (each an
"Advance" and collectively the "Advances") in an aggregate amount not to exceed
the Term Loan, according to each Lender's pro rata share of the Term Loan (based
upon the respective Commitment Percentage of each Lender). Notwithstanding the
foregoing, if Borrower does not request Advances in accordance with the
timetable set forth in the definition of Term Loan, the undrawn amounts shall
not be available for subsequent draw periods. When repaid, the Advances may not
be re-borrowed. Lenders' obligation to lend hereunder shall terminate on the
earlier of (i) the occurrence and continuance of an Event of Default, or (ii)
the Commitment Termination Date. For purposes of this Section, the minimum
amount of each Advance is Five Hundred Thousand Dollars ($500,000.00).

          (b) Borrowing Procedure. To obtain an Advance, Borrower must notify
Agent by facsimile or telephone by 12:00 p.m. Pacific time five (5) Business
Days prior to the date the Advance is to be made. If such notification is by
telephone, Borrower must promptly confirm the notification by delivering to
Agent a completed Payment/Advance Form in the form

<PAGE>

attached as EXHIBIT B (the Payment Advance Form). On the Funding Date, each
Lender shall credit and/or transfer (as applicable) to Borrower's deposit
account, an amount equal to its Commitment Percentage multiplied by the amount
of the Advance. Each Lender may make Advances under this Agreement based on
instructions from a Responsible Officer or his or her designee or without
instructions if the Advances are necessary to meet Obligations which have become
due. Each Lender may rely on any telephone notice given by a person whom such
Lender reasonably believes is a Responsible Officer or designee. Borrower shall
indemnify each Lender for any loss Lender suffers due to such reliance.

     2.2 TERMINATION OF COMMITMENT TO LEND.

     Each Lender's obligation to lend the undisbursed portion of the Obligations
may terminate in the discretion of such Lender if a Key Person departs from the
Borrower and a replacement acceptable to Borrower's Board of Directors is not
named within ninety (90) days of such departure.

     2.3 INTEREST RATE, PAYMENTS.

          (a) Interest Payments. Commencing on the first Payment Date of the
month following the month in which the Funding Date occurs (or commencing on the
Funding Date if the Funding Date is the first calendar day of the month),
Borrower shall make monthly payments of interest at the rate set forth in
Section 2.3(c).

          (b) Repayment. Commencing on July 1, 2006, and continuing on the
Payment Date of each month thereafter, for each Advance, Borrower shall make
consecutive equal monthly payments of principal and interest, in advance,
calculated by Agent based upon: (1) the amount of the Advance, (2) the effective
interest rate calculated as set forth in Section 2.3(c), and (3) an amortization
schedule equal to thirty-six (36) months (individually, the "Scheduled Payment",
and collectively, "Scheduled Payments"). All unpaid principal and accrued
interest is due and payable in full on the Maturity Date. Payments received
after 12:00 p.m. Pacific time are considered received at the opening of business
on the next Business Day. An Advance may only be prepaid in accordance with
Sections 2.3(d) and 2.3(e).

          (c) Interest Rate. Borrower shall pay interest on each Payment Date on
the unpaid principal amount of each Advance until such Advance bas been paid in
full. Interest shall accrue at the per annum rate of interest equal to the Basic
Rate determined by Agent as of the Funding Date for such Advance. Interest is
computed on the basis of a three hundred sixty (360) day year for the actual
number of days elapsed. Any principal outstanding during the continuance of an
Event of Default shall bear interest at a per annum rate equal to the Basic Rate
plus four percent (4%)(the "Default Rate").

          (d) Mandatory Prepayment Upon an Acceleration. If the Advances are
accelerated following the occurrence of an Event of Default or otherwise,
Borrower shall immediately pay to Lenders an amount equal to the sum of: (i) all
outstanding principal plus accrued interest, plus (ii) all other sums, including
the Prepayment Fee, if any, that shall have become due and payable, including
interest at the Default Rate with respect to any past due principal.


                                       -2-

<PAGE>

          (e) Permitted Prepayment of Loans. Borrower shall have the option to
prepay any Advance advanced by Lenders under this Agreement, provided Borrower
(i) provides written notice to Agent of its election to prepay such Advance at
least one (1) day prior to such prepayment, and (ii) pays, on the date of such
prepayment (A) all outstanding principal plus accrued interest with regard to
such Advance, plus (B) all other sums, including the Prepayment Fee, if any,
that shall have become due and payable, including interest at the Default Rate
with respect to any past due principal with regard to such Advance.

          (f) Debit of Accounts. Agent may debit any of Borrower's deposit or
operating accounts including Account Number _________ for principal and interest
payments when due or any amounts Borrower owes Lenders, when due. Agent shall
promptly notify Borrower after it debits Borrower's accounts. These debits shall
not constitute a set-off.

     2.4 FEES.

     Borrower shall pay to Agent:

          (a) Commitment Fee. A fully earned, non-refundable commitment fee of
Twenty Thousand Dollars ($20,000.00) (to be shared between the Lenders pursuant
to their respective Commitment Percentages), due and payable on the Closing
Date;

          (b) Prepayment Fee. The Prepayment Fee, as defined herein, if and when
applicable; and

          (c) Lenders' Expenses. All Lenders' Expenses (including reasonable
attorneys' fees and expenses not exceeding Twenty-Five Thousand Dollars
($25,000.00), plus expenses, for documentation and negotiation of this
Agreement) incurred through and after the Closing Date, when due.

     2.5 ADDITIONAL COSTS. If any law or regulation increases any Lender's costs
or reduces its income for any loan, Borrower shall pay the increase in cost or
reduction in income or additional expense; provided, however, that Borrower
shall not be liable for any amount attributable to any period before 180 days
prior to the date Agent notifies Borrower of such increased costs. Each Lender
agrees that it shall allocate any increased costs among its customers similarly
affected in good faith and in a manner consistent with such Lender's customary
practice.

4 CREATION OF SECURITY INTEREST

     4.1 GRANT OF SECURITY INTEREST. Borrower hereby grants Agent, for the
ratable benefit of the Lenders, to secure the payment and performance in full of
all of the Obligations and the performance of each of Borrower's duties under
the Loan Documents, a continuing security interest in, and pledges and assigns
to Agent, for the ratable benefit of the Lenders, and to each Lender, the
Collateral, wherever located, whether now owned or hereafter acquired or
arising, and all proceeds and products thereof. Subject to Section 5.2, Borrower
warrants and represents that the security interest granted herein shall be a
first priority security interest in the Collateral.

Except as noted on the Perfection Certificate as of the date hereof; Borrower is
not a party to, nor is bound by, any material license (other than over the
counter software that is commercially available to the public) or other material
agreement with respect to which Borrower is the licensee that prohibits or
otherwise restricts Borrower from granting a security interest in Borrower's
interest in such license or agreement or any other property. Borrower shall
provide written notice to Agent within ten (10) days of entering or becoming
bound by, any such license or agreement which is reasonably likely to have a
material impact on Borrower's business or financial condition. Borrower shall
take such steps as Agent reasonably requests to obtain the consent of,
authorization by or waiver by, any person whose consent or waiver is necessary
for all such licenses or contract rights to be deemed "Collateral" and for
Lenders to have a security interest in it that might otherwise be restricted or
prohibited by law or by the terms of any such license or agreement, whether now
existing or entered into in the future.

If Borrower shall, at any time, acquire a commercial tort claim in an amount in
excess of Two Hundred Thousand Dollars ($200,000.00), Borrower shall promptly
notify Agent in a writing signed by Borrower of the brief details thereof and,
upon request of Agent, grant to Agent in writing a security interest therein and
in the proceeds thereof, all upon the terms of this Agreement, with such writing
to be in form and substance satisfactory to Agent.

     4.2 TERMINATION BY BORROWER.

     Borrower may terminate this agreement by sending written notice to Agent
and paying in full all Obligations. If this Agreement is terminated, Lenders'
and Agent's lien and security interest in the Collateral shall continue until
Borrower fully satisfies the Obligations.

     4.3 AUTHORIZATION TO FILE FINANCING STATEMENTS.

     Borrower hereby authorizes Agent to file UCC financing statements, without
notice to Borrower, with all appropriate jurisdictions, in order to perfect or
protect Agent's and Lenders' interest or rights hereunder, including a notice
that any disposition of the Collateral by either Borrower or any other Person,
shall be deemed to violate the rights of the Lenders under the Code.

5 REPRESENTATIONS AND WARRANTIES

     Borrower represents and warrants to Agent and each Lender as follows:

     5.1 DUE ORGANIZATION AND AUTHORIZATION.

     Borrower and each Subsidiary is duly existing and in good standing in its
state of formation and qualified and licensed to do business in, and in good
standing in, any state in which the conduct of its business or its ownership of
property requires that it be qualified, except where the failure to do so would
reasonably be expected to have a material adverse effect on Borrower's business
or operations. In connection with this Agreement, Borrower delivered to Agent
and Lenders a perfection certificate signed by Borrower and entitled "Perfection
Certificate". Borrower represents and warrants to Agent and each Lender that, as
of the date hereof: (a) Borrower's exact legal name is that indicated on the
Perfection Certificate and on the signature page hereof; and (b) Borrower is an
organization of the type, and is organized in the jurisdiction, set forth in the
Perfection Certificate; and (c) the Perfection Certificate accurately sets forth
Borrower's organizational identification number or accurately states that
Borrower has none; and (d) the Perfection Certificate accurately sets forth
Borrower's place of business, or, if more than one, its chief executive office
as well as Borrower's mailing address if different, and (e) all other
information set forth on the Perfection Certificate pertaining to Borrower is
accurate and complete in all material respects. If Borrower does not now have an
organizational identification number, but later obtains one, Borrower shall
forthwith notify Agent of such organizational identification number.

     The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with Borrower's organizational documents,
nor shall they constitute an event of default under any material agreement by
which Borrower is bound. Borrower is not in default under any agreement to which
or by which it is bound in which the default would reasonably be expected to
have a material adverse effect on Borrower's business or operations.

     5.2 COLLATERAL.

     Borrower has good title to the Collateral, free of Liens except Permitted
Liens. As of the date hereof, Borrower has no deposit account, other than the
deposit accounts with Lenders and deposit accounts described in the Perfection
Certificate delivered to Agent and Lenders in connection herewith. Except as
disclosed in the Perfection Certificate, except for co-location arrangements and
except for equipment at prospective customer or customer sites, no portion of
the Collateral with a value in excess of Two Hundred Thousand Dollars
($200,000.00) is in the possession of any third party bailee (such as a
warehouse). Except as hereafter disclosed to the Lenders in writing by Borrower,
none of the components of the Collateral with a value in excess of Two Hundred
Thousand Dollars ($200,000.00) in the aggregate shall be maintained at locations
other than as provided in the Perfection Certificate or at co-locations or at
prospective customer or customer sites. In the event that Borrower, after the
date hereof, intends to store or otherwise deliver any portion of the Collateral
with a value in excess of Two Hundred Thousand Dollars ($200,000.00) in the
aggregate to a bailee (other than co-locations and equipment at customer and
prospective customer sites), then Borrower will first receive the written
consent of


                                       -6-

<PAGE>

Lenders and such bailee must acknowledge in writing that the bailee is holding
such Collateral for the benefit of Agent and Lenders.

     5.3 LITIGATION.

     Except as shown in the Perfection Certificate, there are no actions or
proceedings pending or, to the knowledge of Borrower's Responsible Officers,
threatened against Borrower or any Subsidiary which would reasonably be expected
to have a material adverse effect on Borrower's business or operations.

     5.4 NO MATERIAL DETERIORATION IN FINANCIAL STATEMENTS.

     All consolidated financial statements for Borrower, and any Subsidiary,
delivered to Agent, fairly present in all material respects Borrower's
consolidated financial condition and Borrower's consolidated results of
operations, subject to year end adjustments and the absence of footnotes. As of
the date hereof, there has not been any material deterioration in Borrower's
consolidated financial condition since the date of the most recent financial
statements submitted to Agent.

     5.5 SOLVENCY.

     The fair salable value of Borrower's assets (including goodwill minus
disposition costs) exceeds the fair value of its liabilities; Borrower is not
left with unreasonably small capital after the transactions in this Agreement;
and Borrower is able to pay its debts (including trade debts) as they mature.

     5.6 REGULATORY COMPLIANCE.

     Borrower is not an "investment company" or a company "controlled" by an
"investment company" under the Investment Company Act of 1940. Borrower is not
engaged as one of its important activities in extending credit for margin stock
(under Regulations X, T and U of the Federal Reserve Board of Governors).
Borrower has complied in all material respects with the Federal Fair Labor
Standards Act. Borrower has not violated any laws, ordinances or rules, the
violation of which would reasonably be expected to have a material adverse
effect on Borrower's business or operations. None of Borrower's or any
Subsidiary's properties or assets has been used by Borrower or any Subsidiary
or, to the best of Borrower's knowledge, by previous Persons, in disposing,
producing, storing, treating, or transporting any hazardous substance other than
legally. Borrower and each Subsidiary has timely filed all required tax returns
(or extensions thereof) and paid, or made adequate provision to pay, all
material taxes, except those being contested in good faith with adequate
reserves under GAAP. Borrower and each Subsidiary has obtained all consents,
approvals and authorizations of, made all declarations or filings with, and
given all notices to, all government authorities that are necessary to continue
its business as currently conducted, except where the failure to obtain or make
such consents, declarations, notices or filings would not reasonably be expected
to have a material adverse effect on Borrower's business or operations.

     5.7 SUBSIDIARIES.

     As of the date hereof, Borrower does not own any stock, partnership
interest or other equity securities except for Permitted Investments.

     5.8 FULL DISCLOSURE.

     No written representation, warranty or other statement of Borrower in any
certificate or instrument delivered to Agent or Lenders in connection with this
Agreement (taken together with all such written certificates and written
instruments given to Agent or any Lender) contains any untrue statement of a
material fact or omits to state a material fact necessary to make the statements
contained in the certificates or instruments not misleading, it being recognized
by Agent that the projections and forecasts provided by Borrower in good faith
and based upon reasonable assumptions are not to be viewed as facts and that
actual results during the period or periods covered by such projections and
forecasts may differ from the projected or forecasted results.

     6.5 INSURANCE.

     Borrower shall keep its business and the Collateral insured for risks and

an additional loss payee and all liability policies shall show the Lenders and
Agent as an additional insured and all policies shall provide that the insurer
must give Agent on behalf of Lenders at least twenty (20) days notice before

reasonable time period the failure to have cured such default shall not be
deemed an Event of Default (provided that no Credit Extensions will be made
during such cure period). Grace periods provided under this section shall not
apply, among, other things, to any covenants that are required to be satisfied,
completed or tested by a date certain.

     During the continuance of an Event of Default, Agent may, without notice or
demand, do any or all of the following :

          (a) Declare all Obligations immediately due and payable (but if an
Event of Default described in Section 8.5 occurs all Obligations are immediately
due and payable without any action by Agent and/or Lenders);

          (b) Stop advancing money or extending credit for Borrower's benefit
under this Agreement or under any other agreement between Borrower and Agent
and/or Lenders;

          (c) Settle or adjust disputes and claims directly with account debtors
for amounts, on terms and in any order that Agent considers advisable, and
notify any Person owing Borrower money of Agent's, and Lenders' security
interest in such funds and verify and/or collect the amounts owed by such
account debtor. After the occurrence of an Event of Default, any amounts
received by Borrower shall be held in trust by Borrower for Agent, and, if
requested by Agent, Borrower shall immediately deliver such receipts to Agent in
the form received from the account debtor, with proper endorsements for deposit;

          (d) Make any payments and do any acts it considers necessary or
reasonable to protect its security interest in the Collateral. Borrower shall
assemble the Collateral if Agent requests and make it available as Agent
designates, subject to the rights of third parties. Agent may enter premises
where the Collateral is located, take and maintain possession of any part of the
Collateral, and pay, purchase, contest, or compromise any Lien which appears to
be prior or superior to its security interest and pay all expenses incurred,
subject to the rights of third parties.


                                      -14-

Borrower grants Agent for the benefit of Lenders a license to enter and occupy
any of its premises, without charge, to exercise any of Agent's rights or
remedies;

          (e) Apply to the Obligations any (i) balances and deposits of Borrower
it holds, or (ii) any amount held by Agent or Lenders owing to or for the credit
or the account of Borrower;

          (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare
for sale, advertise for sale, and sell the Collateral, subject to the rights of
third parties. Agent is hereby granted a non-exclusive, royalty-free license or
other right to use, without charge, Borrower's labels, Patents, Copyrights, Mask
Works, rights of use of any name, trade secrets, trade names, Trademarks,
service marks, and advertising matter, or any similar property as it pertains to
the Collateral, in completing production of, advertising for sale, and selling
any Collateral and, in connection with Agent's exercise of its rights under this
Section, Borrower's rights under all licenses and all franchise agreements inure

according to the Code.

     9.2 POWER OF ATTORNEY.

     Borrower hereby irrevocably appoints Agent as its lawful attorney-in-fact,
to be effective upon the occurrence and during the continuance of an Event of
Default, to: (a) endorse Borrower's name on any checks or other forms of payment
or security; (b) sign Borrower's name on any invoice or bill of lading for any
Account or drafts against account debtors; (c) settle and adjust disputes and
claims about the Accounts directly with account debtors, for amounts and on
terms Agent determines reasonable; (d) make, settle, and adjust all claims under
Borrower's insurance policies; and (e) transfer the Collateral into the name of
Agent for the benefit of Lenders or a third party as the Code permits. Borrower
hereby appoints Agent as its lawful attorney-in-fact to sign Borrower's name on
any documents necessary to perfect or continue the perfection of any security
interest regardless of whether an Event of Default has occurred until all
Obligations have been satisfied in full and Agent and Lenders are under no
further obligation to make Credit Extensions hereunder. Agent's foregoing
appointment as Borrower's attorney in fact, and all of Agent's rights and
powers, coupled with an interest, are irrevocable until all Obligations have
been fully repaid and performed and Lenders' and Agent's obligation to provide
Credit Extensions terminates.

     9.3 LENDERS' EXPENSES

     Any amounts paid by Lenders as provided herein shall constitute Lenders'
Expenses and are immediately due and payable, and shall bear interest at the
then applicable rate hereunder and be secured by the Collateral. No payments by
Lenders shall be deemed an agreement to make similar payments in the future or
Agent's and Lenders' waiver of any Event of Default.

<PAGE>

     9.4 AGENT'S AND LENDERS' LIABILITY FOR COLLATERAL.

     So long as Agent and Lenders comply with reasonable banking practices
regarding the safekeeping of Collateral and Section 9-207 of the Code, Agent and
Lenders shall not be liable or responsible for: (a) the safekeeping of the
Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the
value of the Collateral; or (d) any act or default of any carrier, warehouseman,
bailee, or other person. Borrower bears all risk of loss, damage or destruction
of the Collateral.

     9.5 REMEDIES CUMULATIVE.

     Agent's rights and remedies under this Agreement, the Loan Documents, and
all other agreements are cumulative. Agent has all rights and remedies provided
under the Code, by law, or in equity. Agent's exercise of one right or remedy is
not an election, and Agent's waiver of any Event of Default is not a continuing
waiver. Agent's delay is not a waiver, election, or acquiescence. No waiver
hereunder shall be effective unless signed by Agent and each Lender and then is
only effective for the specific instance and purpose for which it was given.

     9.6 DEMAND WAIVER.

     Borrower waives demand, notice of default or dishonor, notice of payment
and nonpayment, notice of any default, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guarantees held by Agent on which Borrower is
liable.

11   CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER

     Massachusetts law governs the Loan Documents without regard to principles
of conflicts of law. Borrower and Lenders, and Agent each submit to the
exclusive jurisdiction of the State and Federal courts in Massachusetts;
provided, however, that if for any reason Lenders cannot avail themselves of
such courts in the Commonwealth of Massachusetts, Borrower accepts jurisdiction
of the courts and venue in Santa Clara County, California. NOTWITHSTANDING THE
FOREGOING, AGENT SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST
BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH AGENT
DEEMS NECESSARY OR APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO
OTHERWISE ENFORCE THE LENDERS' OR AGENT'S RIGHTS AGAINST BORROWER OR ITS
PROPERTY.

     BORROWER, AGENT, AND LENDERS EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY
CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN
DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF
DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES
TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS
COUNSEL.

12   GENERAL PROVISIONS

     12.1 SUCCESSORS AND ASSIGNS.

     This Agreement binds and is for the benefit of the successors and permitted
assigns of each party. Borrower may not assign this Agreement or any rights or
Obligations under it without Agent's prior written consent which may be granted
or withheld in Agent's reasonable discretion. Lenders and Agent have the right,
without the consent of or notice to Borrower, to sell, transfer, assign,
negotiate, or grant participation in all or any part of, or any interest in,
Lenders' obligations, rights and benefits under this Agreement, the Loan
Documents or any


                                      -17-

<PAGE>

related agreement, including, without limitation, an assignment to any Affiliate
or any related party.

     12.2 INDEMNIFICATION.

     Borrower hereby indemnifies, defends and holds Agent and the Lenders and
their respective directors, officers, employees, and agents harmless against:
(a) all obligations, demands, claims, and liabilities asserted by any other
party or Person in connection with the transactions contemplated by the Loan
Documents; and (b) all losses, or Lenders' Expenses incurred, or paid by Lenders
and/or Agent from, following, or consequential to transactions between Lenders
and Borrower (including reasonable attorneys' fees and expenses), except for
losses caused by Lenders' or Agent's gross negligence or willful misconduct.

     12.3 ATTORNEYS' FEES, COSTS AND EXPENSES.

     In any action or proceeding between Borrower and Agent arising out of the
Loan Documents the prevailing party will be entitled to recover its reasonable

     12.4 RIGHT OF SET OFF.

     Borrower hereby grants to Agent for the ratable benefit of Lenders, and to
each Lender, a lien, security interest and right of set off as security for all
Obligations to Agent and each Lender, hereunder, whether now existing or
hereafter arising upon and against all deposits, credits, collateral and
property, now or hereafter in the possession, custody, safekeeping or control of
Agent or any entity under the control of Agent (including an Agent subsidiary)
or in transit to any of them. At any time after the occurrence and during the
continuance of an Event of Default, without demand or notice, Agent or Lenders,
as appropriate, may set-off the same or any part thereof and apply the same to
any liability or obligation of Borrower even though unmatured and regardless of
the adequacy of any other collateral securing the Obligations. ANY AND ALL
RIGHTS TO REQUIRE AGENT TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY
OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF
SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER, ARE
HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

     12.5 TIME OF ESSENCE.

     Time is of the essence for the performance of all Obligations in this
Agreement.

     12.6 SEVERABILITY OF PROVISION.

determining the enforceability of any provision.

and the Loan Documents merge into this Agreement and the Loan Documents.

     12.8 COUNTERPARTS.

continue in full force until this Agreement has terminated pursuant to its
terms, and all Obligations have been satisfied. The obligation of Borrower in
Section 12.2 to indemnify each Lender and Agent shall survive until the statute
of limitations with respect to such claim or cause of action shall have run.

     12.10 CONFIDENTIALITY.

     In handling any confidential information, Lenders and Agent shall exercise
the same degree of care that it exercises for its own proprietary information,
but disclosure of information may be made: (a) to Lenders' and Agent's
subsidiaries or affiliates in connection with their business with Borrower
(provided, however, Lenders and Agent shall use commercially reasonable efforts
in obtaining such subsidiary's or affiliate's agreement to the terms of this
provision); (b) to prospective transferees or purchasers of any interest in the
Credit Extensions (provided, however, Lenders and Agent shall use commercially

agreement to the terms of this provision); (c) as required by law, regulation,
subpoena, or other order; (d) as required in connection with Lenders' and

disclosed to Lenders and/or Agent by a third party, if Lenders and/or Agent does
not know that the third party is prohibited from disclosing the information.
