not be less than $100,000) and (d) in the case of a Fixed Rate Advance or a Fixed Eurodollar
Rate Advance, the Interest Period therefor, and shall promptly confirm any such request by
delivering to the Agent a duly completed and executed Confirmation of Borrowing/Paydown.

The Agent shall notify each Bank by not later than 1:00 p.m. (Denver time) on the date it
receives such request of each request for Warehousing Loans received from the Company, of
the type and amount of Warehousing Loans to be made by such Bank and, in the case of Fixed
Rate Advances and Fixed Eurodollar Rate Advances, the applicable Interest Period. Each Bank
shall deposit into the Settlement Account in Immediately Available Funds by not later than
3:00 p.m. (Denver time) on the Loan Date the total amount of the Warehousing Loans to be
made by such Bank. On the Loan Date of requested Swingline Loans, USBNA may deposit into
the Funding Account in Immediately Available Funds by not later than 4:00 p.m. (Denver time)
on the requested Loan Date the amount of the requested Swingline Loans. Unless the Agent
shall have received notice from a Bank prior to 2:00 p.m. (Denver time) on any Loan Date
that such Bank will not make available to the Agent the Warehousing Loans to be made by such
Bank on such date, the Agent may assume that such Bank has made such Warehousing Loan
available to the Agent on such date and the Agent in its sole discretion may, in reliance
upon such assumption, make available to the Company on such date a corresponding amount on
behalf of such Bank. If a Bank shall not have timely given such a notice, and to the extent
such Bank shall not have so made available to the Agent the Warehousing Loans to be made by
such Bank on such date and the Agent shall have
so made available to the Company a corresponding amount on behalf of such Bank, such Bank
shall, on demand, pay to the Agent such corresponding amount together with interest thereon,
at the Federal Funds Effective Rate, for each day from the date such amount shall have been
so made available by the Agent to the Company until the date such amount shall have been
repaid to the Agent. If such Bank does not pay such corresponding amount promptly upon the
Agent’s demand therefor, the Agent shall promptly notify the Company and the Company shall
immediately repay such corresponding amount to the Agent together with accrued interest
thereon at the applicable rate or rates provided in Section 2.08. Each request for
Warehousing Loans or Swingline Loans shall be deemed to be a representation by the Company
that (i) no Event of Default or Unmatured Event of Default has occurred or will exist upon
the making of the requested Warehousing Loans and (ii) the representations and warranties
contained in Section 3 hereof and in Section 5 of the Pledge and Security Agreement are true
and correct with the same force and effect as if made on and as of the date of such request.

     2.03 Refinancing of Swingline Loans.

     (a) Permitted Refinancings of Swingline Loans. USBNA, at any time in its sole
and absolute discretion, may, upon notice given to each other Bank by not later than 1:00
p.m. (Denver time) on any Business Day, request that each Bank
(including USBNA) make a
Warehousing Loan in an amount equal to its pro rata share of a portion of the aggregate
unpaid principal amount of any outstanding Swingline Loans for the purpose of refinancing
such Swingline Loans. Such Warehousing Loans shall be made as Floating Eurodollar Rate
Advances, unless the Company specifies otherwise.

13

 

     (b) Mandatory Refinancings of Swingline Loans. Not later than 1:00 p.m.
(Denver time) at least on a weekly basis, USBNA will notify each other Bank of the aggregate
amount of Swingline Loans which are then outstanding and the amount of Warehousing Loans
required to be made by each Bank (including USBNA) to refinance such outstanding Swingline
Loans (which shall be in the amount of each Bank’s pro rata share of such outstanding
Swingline Loans). Such Warehousing Loans shall be made as Floating Eurodollar Rate
Advances, unless the Company specifies otherwise.

     (c) Banks’ Obligation to Fund Refinancings of Swingline Loans. Upon the giving
of notice by USBNA under Section 2.03(a) or 2.03(b), each Bank (including USBNA) shall make
a Warehousing Loan in an amount equal to its pro rata share of the aggregate principal
amount of Swingline Loans to be refinanced, and provide proceeds of such Warehousing Loans,
in Immediately Available Funds, by not later than 3:00 p.m. (Denver time) on the date such
notice was received; provided, however, that a Bank shall not be obligated to make any such
Warehousing Loan unless (A) USBNA believed in good faith that all conditions to making the
subject Swingline Loan were satisfied at the time such Swingline Loan was made, or (B) if
the conditions to such Swingline Loan were not satisfied, such Bank had actual knowledge, by
receipt of the statements furnished to it pursuant to Section 4.01 or otherwise, that any
such condition had not been satisfied and failed to notify USBNA in a writing received by
USBNA prior to the time it
made such Swingline Loan that USBNA was not authorized to make a Swingline Loan until
such condition had been satisfied, or USBNA was obligated to give notice of the occurrence
of an Event of Default or an Unmatured Event of Default to the Banks pursuant to Section
6.01 and failed to do so, or (C) any conditions to the making of such Swingline Loan that
were not satisfied had been waived in writing by the Required Banks prior to or at the time
such Swingline Loan was made. The proceeds of Warehousing Loans made pursuant to the
preceding sentence shall be paid to USBNA (and not to the Company) and applied to the
payment of principal of the outstanding Swingline Loans, and the Company authorizes the
Agent to charge the Settlement Account or any other account (other than escrow or custodial
accounts) maintained by the Company with the Agent (up to the amount available therein) in
order to immediately pay USBNA the principal amount of such Swingline Loans to the extent
Warehousing Loans made by the Banks are not sufficient to repay in full the principal of the
outstanding Swingline Loans requested or required to be refinanced. Upon the making of a
Warehousing Loan by a Bank pursuant to this Section 2.03(c), the amount so funded shall
become due under such Bank’s Note and the outstanding principal amount of the Swingline
Loans shall be correspondingly reduced. If any portion of any Warehousing Loan made by the
Banks pursuant to this Section 2.03(c) should be recovered by or on behalf of the Company
from USBNA in bankruptcy or otherwise, the loss of the amount so recovered shall be ratably
shared among all the Banks in the manner contemplated by Section 7.11. Each Bank’s
obligation to make Warehousing Loans referred to in this Section 2.03(c) shall, subject to
the proviso to the first sentence of this Section 2.03(c), be
absolute and unconditional and
shall not be affected by any circumstance, including, without limitation, (1) any setoff,
counterclaim, recoupment, defense or other right which such Bank may have against USBNA, the
Company or anyone else for any reason whatsoever; (2) the occurrence or continuance of a
Default or an Event of Default; (3) any adverse change in the condition (financial or
otherwise) of the Company; (4) any breach of this

14

 

Agreement by the Company, the Agent or any
Bank; or (5) any other circumstance, happening or event whatsoever, whether or not similar
to any of the foregoing; provided, that in no event shall a Bank be obligated to make a
Warehousing Loan if, after giving effect thereto, the outstanding principal balance of such
Bank’s Note would exceed its Commitment Amount.

     2.04 Notes. Warehousing Loans made by each Bank shall be evidenced by the Company’s
promissory note substantially in the form of Schedule 2.04 (each, together with any promissory note
subsequently executed and delivered by the Company to evidence any Bank’s Loans, a “Note”), which
shall be made payable to the order of such Bank in an amount equal to such Bank’s Commitment
Amount, shall be dated the Effective Date and shall mature on the Termination Date. USBNA’s Note
shall also evidence the Swingline Loans made by it hereunder. The aggregate amount of the
Warehousing Loans made by a Bank and, in the case of USBNA, Swingline Loans, less all repayments of
principal thereof shall be the principal amount owing and unpaid on such Bank’s Note. The
principal amount of each Loan made by a Bank and all principal payments and prepayments thereof may
be noted by such Bank on a schedule attached to its Note and shall be entered by such Bank on its
ledgers and computer records. The failure of any Bank to make such notations or entries shall not
affect the principal amount owing
and unpaid on its Note. The entries made by a Bank on its ledgers and computer records and
any notations made by a Bank on any such schedule annexed to its Note shall be presumed to be
accurate until the contrary is established.

     2.05 Payment and Prepayment of Warehousing Loans and Swingline Loans. The Company
shall pay the principal of the Warehousing Loans and Swingline Loans as follows:

     (a) Mandatory Payments. The entire unpaid principal balance of each Bank’s
Note shall be due and payable on the Termination Date.

     (b) Mandatory Prepayments. If, at any time, the aggregate principal amount of
all Loans outstanding exceeds the Borrowing Base, the Company shall immediately either (A)
pledge additional Mortgage Loans with a Collateral Value not less than the amount of such
excess to the Agent for the benefit of the Banks pursuant to the Pledge and Security
Agreement, or (B) make principal prepayments of the Notes in an aggregate amount equal to
the amount of such excess, which amount shall be paid to the Agent and distributed (y)
first, to USBNA as a prepayment on the outstanding principal balance of any Swingline Loans
and (z) after repayment in full of any Swingline Loans, to the Banks ratably on the basis of
each Bank’s pro rata share. In addition, all Swingline Loans shall also be prepayable on
demand therefor by USBNA as provided pursuant to Section 2.03(c).

     (c) Optional Prepayments. The Company shall have the right to prepay, without
penalty (but subject to the provisions of Section 2.19 hereof),
the outstanding principal balance of the Notes in whole or in part at any time and from time to time, each such
principal prepayment to be paid to the Agent and distributed (A) first, to USBNA as a
prepayment on the outstanding principal balance of any Swingline Loans and (B) after
repayment in full of any Swingline Loans, to the Banks ratably on the basis of each Bank’s
pro rata share.

15

 

     (d) Confirmation. The Company shall promptly send the Agent a Confirmation of
Borrowing/Paydown confirming any payment or prepayment of principal made on the Notes.

     2.06 Use of Proceeds. Except as otherwise provided in Section 2.03(c) with respect to
refinancing Swingline Loans, the proceeds of the Swingline Loans and the Warehousing Loans shall be
used to make, originate or acquire Mortgage Loans, to finance Mortgage Loans previously made,
originated or acquired or, in the case of Warehousing Loans made on the Effective Date, to repay in
full the Existing Warehousing Loans.

     2.07 Conversions and Continuations. On the terms and subject to the limitations
hereof, the Company shall have the option at any time and from time to time to convert all or any
portion of the Warehousing Loans or
Swingline Loans into Prime Rate Advances, Fixed Rate Advances (subject, however, to Section
2.08(b)), Fixed Eurodollar Rate Advances or Floating Eurodollar Rate Advances , or to continue a
Fixed Rate Advance or a Fixed Eurodollar Rate Advance as such; provided, however that a Fixed Rate
Advance or a Fixed Eurodollar Rate Advance may be converted or continued only on the last day of
the Interest Period applicable thereto and no Advance may be converted or continued as a Fixed
Eurodollar Rate Advance if an Event of Default or Unmatured Event of Default has occurred and is
continuing on the proposed date of continuation or conversion; and provided, further, that no more
than three (3) Fixed Eurodollar Rate Advances shall be outstanding under any Bank’s Note at any
time. Advances may be converted or continued only in amounts of $100,000 or more. The Company
shall give the Agent and the Banks written notice of any continuation or conversion of any Advance
and such notice must be given so as to be received by the Agent and the Banks not later than 11:00
a.m. (Denver time) two Eurodollar Business Days prior to the date of such continuation or
conversion, in the case of continuation of, or conversion to, a Fixed Eurodollar Rate Advance, and
not later than 11:00 a.m. (Denver time) on the date of such continuation or conversion, in the
case of continuation of, or conversion to, any other type of Advance. Each such notice shall
specify (a) the amount to be continued or converted, (b) the date for the continuation or
conversion (which must be (i) the last day of the preceding Interest Period for any continuation or
conversion of Fixed Rate Advances or Fixed Eurodollar Rate Advances and (ii) a Business Day, in the
case of Fixed Rate Advances, and a Eurodollar Business Day, in the case of Fixed Eurodollar Rate
Advances), and (c) in the case of conversions to or continuations as Fixed Rate Advances or Fixed
Eurodollar Rate Advances, the Interest Period applicable thereto. Any notice given by the Company
under this Section shall be irrevocable. If the Company shall fail to notify the Agent and the
Banks of the continuation of any Fixed Rate Advance or Fixed Eurodollar Rate Advance or of the
conversion of a Fixed Rate Advance to a Eurodollar Rate Advance or vice versa within the time
required by this Section, such Advance shall, on the last day of the Interest Period applicable
thereto, automatically be converted into a Prime Rate Advance of the same principal amount.

     2.08 Interest Rates; Default Interest; Interest Payment Dates. Interest shall accrue
and be payable as follows:

     (a) Each Prime Rate Advance shall bear interest on the unpaid principal amount thereof
at a floating rate per annum equal to the Prime Rate.

16

 

     (b) Each Fixed Rate Advance shall bear interest on the unpaid principal amount thereof
at a rate per annum equal to the Fixed Rate; provided, however, that Fixed Rate Advances
shall not be made by a Bank unless the Company and such Bank shall have entered into a
written agreement (“Side Letter”) which provides for the making of Fixed Rate Advances,
which Side Letter may contain provisions relating to the maintenance of compensating
balances and/or the effect of failure to maintain such compensating balances (including the
payment of additional interest or deficiency fees).

     (c) Each Fixed Eurodollar Rate Advance shall bear interest on the unpaid principal
amount thereof during the Interest Period applicable thereto at a rate per annum equal to
the sum of (i) the Fixed Adjusted Eurodollar Rate for such Interest Period, plus (ii) the
Applicable Margin

     (d) Each Floating Eurodollar Rate Advance shall bear interest on the unpaid principal
amount thereof at a floating rate per annum equal to the sum of (i) the Floating Adjusted
Eurodollar Rate, plus (ii) the Applicable Margin.

     (e) Effective upon notice from the Agent, at the direction of the Required Banks,
whenever any Event of Default shall have occurred and be continuing (whether or not the
maturity of the Notes shall have been accelerated), interest shall accrue on each Advance
until such Event of Default shall have been cured to the written satisfaction of the
Required Banks or, if such Event of Default consists of the Company’s failure to pay the
Agent or any Bank any amount owing under any Loan Document, until such amount shall have
been paid in full, (i) with respect to any Fixed Rate Advance or Fixed Eurodollar Rate
Advance, during the balance of any Interest Period applicable to such Advance, at a rate per
annum equal to the sum of the rate applicable to such Advance during such Interest Period
plus 2.0% per annum, (ii) with respect to any Floating Eurodollar Rate Advance, at a rate
per annum equal to the sum of (A) the Floating Adjusted Eurodollar Rate applicable to such
Advance, plus (B) the Applicable Margin, plus (C) 2% per annum, and (iii) otherwise, at a
rate per annum equal to the sum of the Prime Rate, plus 2.0% per annum.

     (f) Interest shall be payable in arrears on the fifth Business Day of each month and on
the Termination Date; provided that interest under Section 2.08(e) shall be payable on
demand.

     2.09 Facility Fees. The Company shall pay each Bank a facility fee for the period
beginning on the Signing Date and ending on the Termination Date at a per annum rate of one-eighth
of one percent (0.125%) on such Bank’s Commitment Amount, payable for each month in arrears on the
first Business Day of the following month and on the Termination Date.

     2.10 Agent’s Fees. The Company shall pay to the Agent, agent’s fees at such times and
in such amounts as may be agreed upon from time to time in a written agreement (“Side Letter”)
between the Company and the Agent.

     2.11 Payments and Computations.

17

 

     (a) Payment of Principal, Fees and Expenses. All payments and prepayments by
the Company of principal on the Notes and all fees, expenses and other obligations payable
to the Banks under this Agreement (other than interest and fees payable on the Notes and
additional interest or deficiency fees payable under any Side Letter entered into pursuant
to Section 2.08(b), which shall be payable in accordance with Section 2.11(b)) shall be paid
in Immediately Available Funds not later than 12:00 noon (Denver time) on the dates called
for under this Agreement at the main office of the Agent in Minneapolis, Minnesota. Funds
received after such hour shall be deemed to
have been received by the Banks on the next Business Day. The Company irrevocably
authorizes the Agent to charge the Operating Account in an amount equal to any such payment
or permitted prepayment of principal or any such fees, expenses or other obligations, as the
case may be, which are due and payable.

     (b) Payment of Interest and Deficiency Fees. All payments of interest on the
Notes and all additional interest or deficiency fees payable to a Bank under any Side Letter
entered into pursuant to Section 2.08(b) shall be billed to the Company by each Bank with
respect to its Notes and shall be paid by the Company, (i) prior to the occurrence of an
Event of Default, directly to each such Bank, and (ii) upon and during the continuance of an
Event of Default, to the Agent, in either case by not later than 1:00 p.m. (Denver time) on
the dates called for under this Agreement at the respective offices of the Banks or the
Agent, as the case may be, designated on the signature pages of this Agreement. The Company
irrevocably authorizes the Agent and each Bank to charge the Operating Account or any other
demand account of the Company maintained with the Agent or such Bank (other than an account
of the Company with such Bank which the Company holds in escrow or in trust for the benefit
of other Persons) in an amount equal to any such payment of interest, additional interest or
deficiency fees, as the case may be, which are due and payable.

     (c) Computations. Fees and interest on the Notes shall be computed on the
basis of actual days elapsed and a year of 360 days.

     2.12 Setoff. Whenever an Event of Default shall have occurred and be continuing, the
Company hereby irrevocably authorizes each Bank to set off the Indebtedness of the Company to such
Bank under this Agreement (including any Indebtedness owing under any Side Letter), the Notes and
the other Loan Documents against all deposits and credits of the Company with, and any and all
claims of the Company against, such Bank (excluding deposits of the Company with such Bank which
the Company holds in escrow or in trust for the benefit of other Persons), whether or not said
Indebtedness of the Company to such Bank, or any part thereof, shall be then due.

     2.13 Collateral. To secure the payment of Aggregate Outstandings and all other
liabilities of the Company under any Loan Document, the Company from time to time shall grant to
the Agent and the Banks a Security Interest in such of its Mortgage Loans, Mortgage-backed
Securities, Loan Specific Take-Out Commitments, Hedges and other assets as the Company shall
select. All Collateral shall be subject to, and be governed by, the terms and conditions of the
Pledge and Security Agreement.

18

 

     If no Event of Default or Unmatured Event of Default has occurred and is continuing, the Agent
and the Banks, at the request of the Company, shall release their Security Interest in any item of
Collateral; provided, that after giving effect to any such requested release, the Borrowing Base
(including that attributable to any Collateral given in substitution of the Collateral requested to
be released) shall not be less than the Total Outstandings.

     2.14 Termination of Commitments; Reduction of Commitment Amounts.

     (a) Termination. The Company and each Bank shall have the right, prior to any
termination of the Commitments pursuant to Section 6.02, to terminate, with respect to the
Company, any Commitment, and with respect to a Bank, its Commitment, by giving the Agent
notice in writing, specifying the date on which the applicable Commitment is to terminate
(as to such Commitment, the “Commitment Ending Date”), which Commitment Ending Date shall be
no less than 120 days after the Agent gives notice as set forth in the following sentence.
The Agent shall give telephonic notice (confirmed in writing) to each Bank of the Agent’s
receipt of a notice of termination of a Commitment or Commitments given by the Company by
not later than the Agent’s close of business on the third Business Day following the date of
receipt of such notice by the Agent and shall give telephonic notice (confirmed in writing)
to the Company and each other Bank of the Agent’s receipt of a notice of termination by a
Bank of its Commitment by not later than the Agent’s close of business on the third Business
Day following the date of receipt of such notice by the Agent. After receipt from the Agent
of a party’s termination of a Commitment or Commitments, each other party hereto who has not
initially given notice of termination may, in the case of a Bank, terminate its Commitment,
and, in the case of the Company, terminate a Commitment or Commitments, by giving the Agent
telephonic notice (promptly confirmed in writing) of such termination, specifying the
applicable Commitment Ending Date (which may be any date on or after the Commitment Ending
Date specified by the party which gave the initial notice of termination pursuant to the
preceding sentence), within four Business Days after receipt by such party of notice from
the Agent of the Agent’s receipt of the initial notice of termination pursuant to the
preceding sentence. Notwithstanding the foregoing, any termination of the Commitments
pursuant to Section 6.02 hereof shall supersede any notice of termination under this Section
2.14(a).

     (b) Reduction. The Company shall have the right at any time upon at least
seven days prior written notice to the Agent and the Banks to reduce the Commitment Amounts;
provided, that the aggregate amount of each such reduction in the Commitment Amounts shall
be in a minimum amount of $1,000,000 or an integral multiple in excess thereof for each
Bank’s Commitment and shall be apportioned among the Bank’s Commitments in accordance with
their respective Percentage of the Aggregate Commitment Amounts; and provided, further, that
no such reduction shall reduce the Aggregate Commitment Amount to less than Aggregate
Outstandings.

     (c) Effect. Once the Commitments have been terminated pursuant to Section 6.02
or the Commitment Amounts have been reduced, they may not be reinstated.

19

 

     2.15 Interest Rate Not Ascertainable, Etc. If, on or prior to the date for
determining the Fixed Adjusted Eurodollar Rate in respect of the Interest Period for any requested
Fixed Eurodollar Rate Advance, a Bank determines (which determination shall be conclusive and
binding, absent manifest error) that:

     (a) deposits in dollars (in the applicable amount) are not being made available to such
Bank in the relevant market for such Interest Period, or

     (b) the Fixed Adjusted Eurodollar Rate, as the case may be, will not adequately and
fairly reflect the cost to such Bank of funding or maintaining Fixed Eurodollar Rate
Advances, as the case may be, for such Interest Period,

such Bank shall forthwith give notice to the Company and the Agent of such determination, whereupon
the obligation of such Bank to make or continue, or to convert any Advances to, Fixed Eurodollar
Rate Advances, as the case may be, shall be suspended until such Bank notifies the Company and the
Agent that the circumstances giving rise to such suspension no longer exist. No such suspension
shall affect the interest rate then in effect during the applicable Interest Period for any Fixed
Eurodollar Rate Advance outstanding at the time such suspension is imposed.

     2.16 Increased Cost. If any Regulatory Change:

     (a) shall subject a Bank to any tax, duty or other charge with respect to Fixed
Eurodollar Rate Advances, the Note payable to such Bank to the extent it evidences Fixed
Eurodollar Rate Advances, or its obligation to make Fixed Eurodollar Rate Advances, or shall
change the basis of taxation of payment to such Bank of the principal of or interest on
Fixed Eurodollar Rate Advances or any other amounts due under this Agreement in respect of
Fixed Eurodollar Rate Advances or its obligation to make Fixed Eurodollar Rate Advances
(except for changes in the rate of tax on the overall net income of such Bank imposed by the
laws of the United States or any jurisdiction in which such Bank’s principal office is
located); or

     (b) shall impose, modify or deem applicable any reserve, special deposit, capital
requirement or similar requirement (including any such requirement imposed by the Board of
Governors of the Federal Reserve System, but excluding with respect to any Fixed Eurodollar
Rate Advance any such requirement to the extent included in calculating the applicable Fixed
Adjusted Eurodollar Rate, as the case may be) against assets of, deposits with or for the
account of, or credit extended by, such Bank or shall impose on such Bank or on the United
States market for certificates of deposit any other condition affecting Fixed Eurodollar
Rate Advances, its Note or its obligation to make Fixed Eurodollar Rate Advances;

and the result of any of the foregoing is to increase the cost to such Bank of making or
maintaining any Fixed Eurodollar Rate Advance, or to reduce the amount of any sum received
or receivable by such Bank under this Agreement or under its Note, then, within 30 days
after demand by such Bank, the Company shall pay to such Bank such additional amount or
amounts as will compensate such Bank for such increased cost or reduction.

20

 

Such Bank will
promptly notify the Company of any event of which it has knowledge, occurring after the date
hereof, which will entitle such Bank to compensation pursuant to this Section. A
certificate of such Bank claiming compensation under this Section,
setting forth the additional amount or amounts to be paid to it hereunder and stating in
reasonable detail the basis for the charge and the method of computation, shall be
conclusive in the absence of manifest error. In determining such amount, such Bank may use
any reasonable averaging and attribution methods. Failure on the part of such Bank to
demand compensation for any increased costs or reduction in amounts received or receivable
with respect to any Interest Period shall not constitute a waiver of such Bank’s rights to
demand compensation for any increased costs or reduction in amounts received or receivable
in any subsequent Interest Period.

     2.17 Illegality. If any Regulatory Change shall make it unlawful or impossible for a
Bank to make, maintain or fund Fixed Eurodollar Rate Advances, such Bank shall notify the Company,
whereupon the obligation of such Bank to make Fixed Eurodollar Rate Advances, as the case may be,
shall be suspended until such Bank notifies the Company that the circumstances giving rise to such
suspension no longer exist. If such Bank determines that it may not lawfully continue to maintain
any outstanding Fixed Eurodollar Rate Advances to the end of the applicable Interest Periods, all
of the affected Advances shall be automatically converted to Prime Rate Advances as of the date of
such Bank’s notice, and upon such conversion the Company shall indemnify such Bank in accordance
with Section 2.19.

     2.18 Capital Adequacy. In the event that any Regulatory Change reduces or shall have
the effect of reducing the rate of return (by an amount such Bank deems material) on the capital of
a Bank or on the capital of such Bank’s parent corporation as a consequence of such Bank’s
Commitment and/or the Loans made by such Bank to a level below that which the Bank or its parent
could have achieved but for such Regulatory Change (taking into account the policies of such Bank
and its parent corporation with respect to capital adequacy), then the Company shall, within 30
days after written notice and demand from such Bank, pay to such Bank additional amounts sufficient
to compensate such Bank or its parent corporation for such reduction; provided, however, that the
Company shall not be obligated to pay any such amount or amounts (i) unless such Bank shall have
first notified the Company in writing that it intends to seek compensation from the Company
pursuant to this sentence, and (ii) which are attributable to periods exceeding 180 days prior to
the date of receipt by the Company of such notice. A certificate as to the amount of any such
reduction (including calculations in reasonable detail showing how such Bank computed such
reduction and a statement that the Bank has not allocated to its Commitment or its outstanding
Advances a proportionately greater amount of such reduction than is attributable to each of its
other commitments to lend or to each of its other outstanding credit extensions that are affected
similarly by such compliance by such Bank, whether or not such Bank allocates any portion of such
reduction to such other commitments or credit extensions) shall be furnished promptly by such Bank
to the Company. Any determination by a Bank under this Section and any certificate as to the
amount of such reduction given to the Company by such Bank shall be final, conclusive and binding
for all purposes, absent manifest error.

     2.19 Funding Losses. Upon the written request of a Bank, the Company shall compensate such Bank for all losses,
expenses and liabilities (including any interest paid by such

21

 

Bank to lenders of funds borrowed by
it to make or carry Fixed Eurodollar Rate Advances to the extent not recovered by such Bank in
connection with the re-employment of such funds and including loss of anticipated profits) which
such Bank may sustain: (a) if for any reason, other than a default by such Bank, a funding of a
Fixed Eurodollar Rate Advance does not occur on the date specified therefor in the Company’s
request or notice as to such Advance under Section 2.02, or (b) if, for whatever reason (including
acceleration of the maturity of such Bank’s Note following an Event of Default), any repayment of a
Fixed Eurodollar Rate Advance pursuant to Section 2.05 or otherwise, or a conversion pursuant to
Section 2.07, occurs on any day other than the last day of the Interest Period applicable thereto.
The Bank’s request for compensation shall set forth the basis for the amount requested and shall be
final, conclusive and binding, absent manifest error.

     2.20 Discretion of Banks as to Manner of Funding. Each Bank shall be entitled to fund
and maintain its funding of Fixed Eurodollar Rate Advances in any manner it may elect, it being
understood, however, that for the purposes of this Agreement all determinations hereunder
(including determinations under Section 2.19) shall be made as if the Bank had actually funded and
maintained each Fixed Eurodollar Rate Advance during the Interest Period for such Advance through
the issuance of its certificates of deposit, or the purchase of deposits, having a maturity
corresponding to the last day of the Interest Period.

     Section 3 REPRESENTATIONS AND WARRANTIES.

     To induce the Banks to grant the Commitments, the Company represents and warrants that:

occur, the Commitments shall immediately terminate and the principal of and accrued interest on the
Notes shall become immediately due and payable all without further notice of any kind. If any
other Event of Default shall occur, the Agent, at the direction of the Required Banks, shall
terminate the Commitments and shall declare the principal of and accrued interest on the Notes

33

 

to
be immediately due and payable, whereupon the Commitments shall terminate immediately and the Notes
shall become immediately due and payable, all without further notice of any kind.

     Section 7 THE AGENT.

     7.01 Appointment and Authorization. Each Bank appoints and authorizes the Agent to
take such action as agent on its behalf and to exercise such powers under this Agreement and the
other Loan Documents as are delegated to the Agent by the terms thereof, together with such powers
as are reasonably incidental thereto. Each Bank also appoints the Agent to act as Collateral Agent
under the Pledge and Security Agreement and to take such action as Collateral Agent thereunder and
to exercise such powers under the Pledge and Security Agreement as are reasonably incidental
thereto. Neither the Agent (acting as Agent or Collateral Agent) nor any of its directors,
officers or employees shall be liable for any action taken or omitted to be taken by it or them
under or in connection with this Agreement or the other Loan Documents, except for its or their own
gross negligence or willful misconduct. The Agent shall act as an independent contractor in
performing its obligations as Agent hereunder and under the other Loan Documents (including,
without limitation, the Pledge and Security Agreement) and nothing herein contained shall be deemed
to create a fiduciary relationship among or between the Agent, the Company or the Banks.

     7.02 Note Holders. The Agent may treat the payee of any Note as the holder thereof
until written notice of transfer shall have been filed with it signed by such payee and in form
satisfactory to the Agent.

     7.03 Consultation With Counsel. The Agent may consult with legal counsel selected by
it and shall not be liable for any action taken or suffered in good faith by it in accordance with
the advice of such counsel.

     7.04 Documents. The Agent shall not be under a duty to examine into or pass upon the
validity, effectiveness, genuineness or value of the Notes, the Loan Documents or any other
instrument or document furnished pursuant thereto or thereunder, and the Agent shall be entitled to
assume that the same are valid, effective and genuine and what they purport to be.

     7.05 Agent and Affiliates. With respect to its Commitment and the Loans and Advances
made by it in its capacity as a Bank, the Agent shall have the same rights and powers under this
Agreement and the other Loan Documents as any other Bank and may exercise the same as though it
were not the Agent consistent with the terms thereof, and the Agent and its affiliates may accept
deposits from, lend money to and generally engage in any kind of business with the Company or any
Subsidiary as if it were not the Agent.

     7.06 Action by Agent. The Agent shall be entitled to use its discretion with respect
to exercising or refraining from exercising any rights which may be vested in it by, or with
respect to taking or refraining from taking any action or actions which it may be able to take
under or in respect of, this Agreement and the Loan Documents. The Agent shall incur no liability
under or in respect of this Agreement or any of the Loan Documents by acting upon any notice,
consent, certificate, warranty or other paper or instrument believed by it to be genuine or
authentic or to be signed by the proper party or parties, or with respect to anything which it may
do or refrain

34

 

from doing in the reasonable exercise of its judgment, or which may seem to it to be
necessary or desirable in the premises.

     7.07 Credit Analysis. Each Bank has made, and shall continue to make, its own
independent investigation or evaluation of the operations, business, property and condition,
financial and otherwise, of the
Company, in connection with the making of its Commitment and has made its own appraisal of the
creditworthiness of the Company. Except as explicitly provided herein, the Agent has no duty or
responsibility, either initially or on a continuing basis, to provide any Bank with any credit or
other information with respect to such operations, business, property, condition or
creditworthiness, whether such information comes into its possession on or before the Effective
Date or at any time thereafter.

     7.08 Notices of Event of Default, etc. In the event that any Bank shall have acquired
actual knowledge of any Event of Default or Unmatured Event of Default, such Bank shall promptly
give notice thereof to the Agent and the other Banks. Upon receipt from any Bank of a request that
the Agent give notice to the Company of the occurrence of an Event of Default or Unmatured Event of
Default under Section 6, the Agent shall promptly forward such request to the other Banks and will
take such action and assert such rights under this Agreement and the other Loan Documents as the
Required Banks shall direct in writing.

     7.09 Indemnification. Each Bank agrees to indemnify the Agent (to the extent not
reimbursed by the Company), ratably according to its Percentage of the Aggregate Commitment Amount,
from and against any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against the Agent in any way relating to or arising out of this
Agreement or the Loan Documents or any action taken or omitted by the Agent under this Agreement or
the Loan Documents provided that no Bank shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the Agent’s gross negligence or willful misconduct.

     7.10 Payments. All payments of principal of the Notes and all other funds received by
the Agent in respect of any payments made by the Company pursuant to this Agreement, the Notes or
the other Loan Documents (other than payments of interest payable on the Banks’ Notes, payments of
agent fees made to the Agent under its Side Letter, payments of additional interest or deficiency
fees made to the Banks pursuant to Section 2.08(b) and the provisions of any Side Letter) shall be
distributed forthwith by the Agent (in like currency and funds and on the same day received,
provided that any such payment is received by the Agent prior to 12:00 noon (Denver time) on such
day) to the Banks ratably in accordance with each Bank’s Percentage of the Aggregate Outstandings
and in like currency and funds and on the same day as received.

     7.11 Sharing of Payments. If any Bank shall receive and retain any payment during the
persistence of an Event of Default or Unmatured Event of Default, whether by setoff, application of
deposit balance or security, or otherwise, in respect of indebtedness under this Agreement or the
Notes in excess of such Bank’s share based on its Percentage of the Aggregate Outstandings, then
such Bank shall purchase from the other Banks for cash and at face value and without recourse, such
participation
in the Notes held by them as shall be necessary to cause such excess payment to be shared
ratably as aforesaid with each of them; provided, that if such

35

 

excess payment or part thereof is
thereafter recovered from such purchasing Bank, the related purchases from the other Bank shall be
rescinded ratably and the purchase price restored as to the portion of such excess payment so
recovered, but without interest. Each Bank agrees to exercise any and all rights of setoff,
counterclaim or bankers’ lien first fully against any such Notes and participations therein held by
such Bank, and only then to any other indebtedness of the Company to such Bank.

     7.12 Advice to Banks. The Agent shall forward to the Banks copies of all notices,
financial reports and other communications received from the Company hereunder. In addition, the
Agent will provide monthly collateral and collateral aging reports to each of the Banks.

     7.13 Resignation and Removal.

     (a) The Agent may resign at any time by giving 30 days written notice thereof to the
Banks and the Company. Upon any such resignation, the Required Banks shall have the right
to appoint a successor Agent, which successor Agent shall (unless an Event of Default has
then occurred and is continuing) be reasonably acceptable to the Company. If no successor
Agent shall have been so appointed and shall have accepted such appointment within 30 days
after the retiring Agent’s giving of notice of its resignation, then the retiring Agent may,
on behalf of the Banks, appoint an Agent or custodian which shall be a Bank or a commercial
bank organized under the laws of the United States of America or of any State thereof and
having a combined capital and surplus of at least $100,000,000 and which shall be reasonably
acceptable to the Company (unless an Event of Default has occurred and is continuing). Any
such resignation shall be effective upon the appointment of a successor Agent. Upon the
acceptance of any appointment as the Agent hereunder by a successor Agent, such successor
Agent shall thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties
and obligations, under this Agreement and the other Loan Documents. After any retiring
Agent’s resignation or removal hereunder as the Agent, the provisions of this Section 7
shall inure to its benefit as to any actions taken or omitted to be taken by it while it was
acting as the Agent under this Agreement and any other Loan Document.

     (b) If the Agent is placed in receivership or conservatorship or ceases to be eligible
to serve as depository or document custodian on behalf of FNMA, FHLMC or GNMA, the Required
Banks (excluding the Agent in its capacity as a Bank) shall have the right to remove the
Agent upon written notice to the Agent. Upon submission of such notice, such Required Banks
may designate a successor agent.

     Section 8 MISCELLANEOUS.

     8.01 Non-Waiver. No failure on the part of the Agent or the Banks to exercise and no
delay in exercising, and no course of dealing with respect to, any right, power or privilege under
this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any
right, power or privilege under this Agreement preclude any other or
further exercise thereof or the exercise of any other right, power or privilege. The remedies provided herein are cumulative
and not exclusive of any remedies provided by law.

36

 

     8.02 Notices. Except as otherwise specifically provided for herein, all notices and
other communications provided for herein shall be by telex, telecopier, telegraph, cable or in
writing and telexed, telecopied, telegraphed, cabled, mailed or delivered to the intended recipient
at the address specified on the signature pages hereto; or, as to any party, at such other address
as shall be designated by such party in a notice to the other parties. All notices and other
communications hereunder shall be deemed to have been duly given when transmitted by telex or
telecopier, delivered to the telegraph or cable office or personally delivered or, in the case of a
mailed notice, upon receipt thereof as conclusively evidenced by the signed receipt therefor, in
each case given or addressed as aforesaid.

     8.03 Expenses; Indemnification.

     (a) Expenses. The Company agrees to pay: (i) the reasonable fees and expenses
of counsel for the Agent and the Banks in connection with the preparation, execution and
delivery of this Agreement, the Notes and the other Loan Documents and in connection with
the Loans hereunder, whether or not any Loan is made hereunder, (ii) the reasonable fees and
expenses of counsel for the Agent and the Banks in connection with any amendment,
modification or waiver of any of the terms of this Agreement, the Notes and the other Loan
Documents and (iii) all reasonable costs and expenses of the Agent and the Banks (including
reasonable counsels’ fees) in connection with the enforcement of this Agreement, the Notes
and the other Loan Documents. Fees and expenses of counsel for the Agent shall be
determined based upon such counsel’s generally applicable rates which may be higher than the
rates charged to the Agent in certain matters.

     (b) Indemnification.

     (i) The Company will indemnify and hold harmless the Agent and each Bank, the
Agent’s and each Bank’s directors, officers, employees, agents and attorneys and
each Person, if any, who is deemed to control the Agent or any Bank (any and all of
whom are referred to as the “Indemnified Party”) from and against any and all
losses, claims, damages and liabilities, joint or several (including all losses,
claims, damages and liabilities resulting from the negligence, but not the gross
negligence of such Indemnified Party, and including all legal fees or other expenses
reasonably incurred by any Indemnified Party in connection with the preparation for
or defense of any pending or threatened claim,
action or proceeding, whether or not resulting in any liability), to which such
Indemnified Party may become subject (whether or not such Indemnified Party is a
party thereto) under any applicable Federal, state or local law or otherwise caused
by or arising out of, or allegedly caused by or arising out of, this Agreement or
any transaction contemplated hereby, except for losses, claims, damages or
liabilities resulting from the gross negligence, willful misconduct or fraud of such
Indemnified Party or the failure of such Indemnified Party to fulfill its
obligations under this Agreement.

     (ii) Promptly after receipt by an Indemnified Party of notice of any claim,
action or proceeding with respect to which an Indemnified Party is entitled to
indemnity hereunder, such Indemnified Party will notify the Company of such

37

 

claim or
the commencement of such action or proceeding, provided that the failure of an
Indemnified Party to give notice as provided herein shall not relieve the Company of
its obligations under this Section 8.03(b) with respect to such Indemnified Party,
except to the extent that the Company is actually prejudiced by such failure. The
Company will assume the defense of such claim, action or proceeding and will employ
counsel reasonably satisfactory to the Indemnified Party and will pay the fees and
expenses of such counsel. Notwithstanding the preceding sentence, the Indemnified
Party will be entitled, at the expense of the Company, to employ counsel separate
from counsel for the Company and for any other party in such action if the
Indemnified Party reasonably determines that a conflict of interest or other
reasonable basis exists which makes representation by counsel chosen by the Company
not advisable, provided that the Company shall not be obligated to pay for the fees
and expenses of more than one counsel for all Indemnified Parties in respect of a
particular controversy. In the event an Indemnified Party appears as a witness in
any action or proceeding brought against the Company or any of its Subsidiaries (or
any of its officers, directors or employees) in which an Indemnified Party is not
named as a defendant, the Company agrees to reimburse such Indemnified Party for all
expenses incurred by it (including fees and expenses of counsel) in connection with
its appearing as a witness.

     (c) The Banks agree to the indemnification provisions set forth in Section 21.08 of the
Pledge and Security Agreement.

     8.04 Taxes. The Company agrees to pay, and save the Agent, the Collateral Agent and
the Banks harmless from all liability for, any stamp or other taxes which may be payable with
respect to the execution or delivery of this Agreement or the issuance of the Notes and the
Security Documents, which obligation of the Company shall survive the termination of this
Agreement.

     8.05 Amendments, Etc.

     (a) Except as provided in Sections 8.05(b) and 8.05(c), no amendment or waiver of any
of the provisions of this Agreement, the Notes or the Loan Documents, nor any consent to any
departure by the Company from the provisions hereof or thereof, shall be effective unless
the same shall be in writing and signed by the Required Banks, and then any such waiver or
consent shall be effective only in the specific instance and for the specific purpose for
which given; provided, however, that no such amendment, waiver or consent shall, unless in
writing and signed by all of the Banks, do any of the following: (i) waive any of the
conditions specified in Section 2, (ii) increase the Commitment Amounts of the Banks, except
as provided in Sections 8.05(b) and 8.05(c), or subject the Banks to any additional
obligations, (iii) reduce the principal of, or interest on the Notes or any fees payable to
the Banks hereunder, (iv) postpone any date fixed for any payment in respect of principal
of, or interest on, the Notes or any fees payable to the Banks hereunder, (v) change the
Percentage of the Aggregate Commitment Amount or the Percentage of the Aggregate
Outstandings as to any Bank, except as provided in Sections 8.05(b) and 8.05(c), or the
number or identity of the Banks which shall be

38

 

required for the Banks or any of them to take
any action hereunder, (vi) amend this Section 8.05, Section 2.08(b), Section 6, Section 8.06
or Exhibit A hereto, (vii) release any Collateral, except as is provided in Sections 9 and
10 of the Pledge and Security Agreement, (viii) amend the definitions of “Collateral” set
forth in the Pledge and Security Agreement, or (ix) permit the release of Collateral not
otherwise permitted to be released under the terms of the Loan Documents as constituted
prior to such amendment; and provided, further, that no such amendment, waiver or consent
shall, unless in writing and signed by the Agent, and, if applicable, the Collateral Agent,
in addition to the Banks required hereinabove to take such action, affect the rights or
duties of the Agent or the Collateral Agent under this Agreement, any Note or the other Loan
Documents.

     (b) From time to time, so long as no Event of Default is then continuing, the Company
may agree, with the prior written consent of the Agent, to add a bank chartered under the
laws of the United States or any State thereof, an insurance company, another lender or a
mutual fund (a “New Bank”) as a “Bank” under this Agreement with a Commitment, for the
purpose of increasing the aggregate amount of the Commitments; provided, however, that upon
giving effect to any such new Commitment, the Commitment Amount of the New Bank shall not be
less than $10,000,000; and provided, further, that the aggregate Commitment Amounts, after
giving effect to any such increase, shall not exceed $400,000,000 (except as otherwise
provided in (c) below). The Company, the Agent and each New Bank shall agree on the date as
of which the New Bank’s Commitment Amount shall become effective, and each New Bank shall
execute and deliver an instrument in the form prescribed by the Agent to evidence its
agreement to be bound by this Agreement and the other Loan Documents. Upon the effective
date of the inclusion of a New Bank as a lender under this Agreement, the Agent shall
deliver to the Company and each of the Banks a revised Schedule 1.01(b) reflecting the
revised aggregate Commitment Amounts and the Company shall execute and deliver to the New
Bank a Note in the amount of the New Bank’s Commitment Amount. Any reallocation of Loans
outstanding on the date that the New Bank’s Commitment Amount shall become effective
necessitated by the addition of the New Bank as a Bank under this Agreement shall be
effected on and as of such date by the purchase and sale among the Banks of the obligations
outstanding on such date.

     (c) From time to time, so long as no Event of Default is then continuing, the Company
may agree, with the prior written consent of the Agent, to permit a Bank to permanently or
temporarily increase its Commitment Amount for the purpose of increasing the aggregate
amount of the Commitments; provided, however, that the aggregate Commitment Amounts, after
giving effect to any such increase, shall not exceed $400,000,000. The Company, the Agent
and each Bank increasing its Commitment Amount shall agree on the date as of which the
increased Commitment Amount shall become effective and, if such increase is a temporary
rather than a permanent increase, the date on which that increase shall terminate (the
“Temporary Increase Termination Date”). Upon the effective date of an increase in any
Bank’s Commitment Amount under this Agreement, the Agent shall
deliver to the Company and each of the Bank’s a revised Schedule 1.01(b) reflecting the revised aggregate Commitment
Amounts and the Company shall execute and deliver to the Bank increasing its Commitment

39

 

Amount shall become
effective shall be effected on and as of such date by the purchase and sale among the Banks
of the Loans outstanding on such date. If an increase in a Bank’s Commitment Amount was a
temporary rather than a permanent increase, the Company shall, on the Temporary Increase
Termination Date, repay the Loans by the amount by which the outstanding principal balance
of all Loans on such date exceeds the sum of the Commitment Amounts, after giving effect to
the termination of such temporary increase. Notwithstanding the existence of any Event of
Default or Unmatured Event of Default or any other failure to satisfy the conditions
pursuant to Warehousing Loans under this Agreement, each of the Banks (other than the Bank
that temporarily increased its Commitment Amount) shall make Warehousing Loans on such date
in the amount, if any, required to increase its outstanding Warehousing Loans to its
Percentage of the Aggregate Commitment Amount, and shall deliver the proceeds of such
Warehousing Loans to the Agent. The Agent shall distribute to the Bank that temporarily
increased its Commitment Amount on such date, out of any payments made by the Company as set
forth above and the proceeds of Warehousing Loans made by the other Banks as set forth
above, the amount required to reduce such Bank’s outstanding Warehousing Loans to its
Percentage of the Aggregate Commitment Amount.

     8.06 Successors and Assigns; Disposition of Advances; Transferees.

     (a) This Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Company may not assign its
rights or obligations hereunder or under the Notes without the prior consent of all of the
Banks.

     (b) Any Bank may at any time sell, assign, transfer, grant participations in, or
otherwise dispose of any portion of its Notes and the Loans made by such Bank (each such
interest so disposed of being herein called a “Transferred Interest”) to banks or other
entities which meet the minimum financial rating requirements established by FNMA, FHLMC and
GNMA for custodial depositories that are FDIC-insured (“Transferees”).
Without in any way limiting the rights of Transferees hereunder, the Company agrees
that each Transferee shall be entitled to the benefits of Sections 2.16, 2.17, 2.18, 2.19
and 2.20 to the extent of its Transferred Interest as if it were the “Bank” which has made
Loans in an aggregate amount equal to such Transferred Interest. The Company agrees that
each Transferee may exercise any and all rights of banker’s lien, setoff as provided in
Section 2.12 and counterclaim available pursuant to law with respect to its Transferred
Interest as fully as if such Transferee were a direct lender to the Company.

     (c) Each Bank may pledge any portion of its Note for security purposes to any Federal
Reserve Bank.

     8.07 Confidentiality. Any information which the Agent or any Bank receives from the
Company which is designated proprietary or confidential at the time
of receipt thereof by the Agent
or such Bank shall not be disclosed by the Agent or such Bank to any other Person, if such
information is not otherwise in the public domain, other than (a) to its independent accountants
and legal counsel, (b) pursuant to statutory or regulatory requirements, (c) pursuant to any

40

 

mandatory court order or (d) to any Transferee or prospective Transferee and to the independent
accountants and legal counsel of any such Transferee or prospective Transferee.

     8.08 Survival. The obligations of the Company under Sections 2.09, 2.16, 2.18 and
8.03 shall survive the repayment of the Notes and the termination of the Commitments; provided,
however, that the obligations of the Company under Sections 2.16 and 2.18 shall survive only with
respect to the payment of compensation for increased costs, reduction in amounts received or
receivable or reduced return attributable to periods prior to the repayment of the Notes and the
termination of the Commitments.

     8.09 Counterparts. This Agreement may be executed in any number of counterparts, and
by different parties hereto in separate counterparts, each of which when so executed and delivered
shall be deemed an original, but all of which taken together shall constitute one and the same
instrument.

     8.10 GOVERNING LAW. THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE INTERNAL LAW, AND NOT THE LAW OF CONFLICTS, OF THE STATE OF MINNESOTA, BUT
GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS. Whenever possible, each provision of
this Agreement and the Notes and any other statement, instrument or transaction contemplated hereby
or thereby or relating hereto or thereto shall be interpreted in such manner as to be effective and
valid under such applicable law, but, if any provision of this Agreement or the Notes or any other
statement, instrument or transaction contemplated hereby or thereby or relating hereto or thereto
shall be held to be prohibited or invalid under such applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this Agreement and
the Notes and any other statement, instrument or transaction contemplated hereby or thereby or
relating hereto or thereto.

     8.11 WAIVER OF JURY TRIAL; JURISDICTION.

     (a) THE COMPANY, BY ITS EXECUTION AND DELIVERY HEREOF, AND EACH OF THE AGENT AND THE
BANKS, BY THEIR ACCEPTANCE HEREOF, HEREBY EXPRESSLY WAIVES ANY RIGHT TO A TRIAL BY JURY IN
ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS AGREEMENT, THE NOTES OR
THE LOAN DOCUMENTS OR UNDER ANY AMENDMENT, INSTRUMENT OR DOCUMENT DELIVERED OR WHICH MAY IN
THE FUTURE BE DELIVERED IN CONNECTION HEREWITH OR ARISING FROM ANY CREDIT RELATIONSHIP
EXISTING IN CONNECTION WITH THIS AGREEMENT, THE NOTES OR THE LOAN DOCUMENTS, AND AGREES THAT
ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

     (b) THE COMPANY HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF ANY MINNESOTA STATE
OR FEDERAL COURT SITTING IN HENNEPIN OR RAMSEY COUNTY, MINNESOTA OVER ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE

41

 

NOTES OR THE LOAN DOCUMENTS.
THE COMPANY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT IT MAY EFFECTIVELY DO SO, THE
DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING. NOTHING
IN THIS SECTION 8.11(b) SHALL AFFECT THE RIGHT OF THE AGENT AND THE BANKS TO BRING ANY
ACTION OR PROCEEDING AGAINST THE COMPANY OR ITS PROPERTY IN THE COURTS OF ANY OTHER
JURISDICTION.

     8.12 Highest Lawful Rate. Anything herein to the contrary notwithstanding, the
obligations of the Company on each Bank’s Note shall be subject to the limitation that payments of
interest shall not be required, for any period for which interest is computed hereunder, to the
extent that contracting for or receipt thereof would be contrary to provisions of any law
applicable to such Bank limiting the highest rate of interest which may be lawfully contracted for,
charged or received by such Bank.

     8.13 Section Titles. The section titles contained in this Agreement shall be without
substantive meaning or content of any kind whatsoever and shall not govern the interpretation of
any of the provisions of this Agreement.

     8.14 Reliance by the Agent and the Banks. All covenants, agreements, representations and warranties made herein by the Company shall,
notwithstanding any investigation by the Agent and the Banks, be deemed to be material to and to
have been relied upon by the Agent and the Banks and shall survive the execution and delivery of
this Agreement.

     8.15 Severability. Any provision of this Agreement which is prohibited or
unenforceable shall be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof.

     8.16 ENTIRE AGREEMENT. THIS AGREEMENT AND ALL LOAN DOCUMENTS EMBODY THE FINAL, ENTIRE
AGREEMENT AMONG THE PARTIES HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS,
REPRESENTATIONS AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF,
AND MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL
AGREEMENTS OR DISCUSSIONS OF THE PARTIES HERETO.

          The Collateral Agent shall exercise reasonable care in the custody and preservation of the
Collateral and shall keep the Collateral separate from similar collateral furnished by third
parties. As between the Pledgor and the Collateral Agent, the Collateral Agent shall be deemed to
have exercised reasonable care in the custody and preservation of any of the Collateral in its
possession if it takes such action for that purpose as Pledgor requests in writing, but failure of
the Collateral Agent to comply with any such request shall not itself be deemed a failure to
exercise reasonable care, and no failure of the Collateral Agent to preserve or protect any rights
with respect to such Collateral not so requested by Pledgor shall be deemed a failure to exercise
reasonable care in the custody or preservation of such Collateral. The Collateral Agent shall also
be deemed to have exercised reasonable care in the safekeeping of any Collateral in its possession
if such Collateral is accorded treatment substantially equal to the safekeeping which the
Collateral Agent accords to its own property of like kind.

          Section 7. COLLECTIONS ON COLLATERAL BY THE PLEDGOR; ACCOUNTING.

          Until the Agent gives notice to the Pledgor pursuant to the penultimate sentence of this
Section 7 or exercises the Agent’s rights under Sections 8 or 13, the Pledgor shall be entitled to
receive all Collections and use the same in the normal course of business. Upon notice from the
Agent to the Pledgor given after the occurrence and during the continuation of an Event of Default
or an Unmatured Event of Default, the Pledgor shall furnish to the Pledgees not later

C-10

 

than the
tenth Business Day after the end of each month a report on all Collections received during the
preceding month and provide the same accounting therefor as the Pledgor customarily furnishes the
permanent investors therein, including with respect to Collections on each Pledged Mortgage Loan:
(a) the name of the borrower, (b) Pledgor’s loan number for the Pledged Mortgage Loan, (c) current
principal balance of the Pledged Mortgage Loan, (d) current escrow balance with respect to the
Pledged Mortgage Loan, (e) number and amount of past due payments on the Pledged Mortgage Loan and
(f) the amount of the collections received during such month with respect to the Pledged Mortgage
Loan, itemized to show (i) principal portion, (ii) interest portion and (iii) portion thereof
representing amounts paid in escrow for real estate taxes and insurance.

          Upon notice from the Agent, at the direction of the Required Banks, to the Pledgor given after
the occurrence and during the continuation of an Event of Default or of an Unmatured Event of
Default, the Pledgor shall hold all Collections representing principal payments and prepayments and
escrows for real estate taxes and insurance in trust for the Pledgees and shall promptly remit the
same to the Agent or such other person as may be designated by the Required Banks. All amounts
representing the principal payments and prepayments delivered to the Agent pursuant to the
preceding sentence shall be deposited in the Settlement Account and all amounts representing real
estate taxes and insurance escrows delivered to the Agent pursuant to the
preceding sentence shall be deposited in an escrow account with any bank satisfactory to the
Pledgor and the Required Banks.

          Section 8. COLLECTIONS ON COLLATERAL BY THE AGENT.

          Upon the occurrence and during the continuation of an Event of Default or an Unmatured Event
of Default, the Collateral Agent at the direction of the Required Banks, shall be entitled, but not
obligated, at any time and from time to time, to notify and direct any or all Obligors with respect
to any of the Collateral thereafter to make all payments on such Collateral directly to the Agent
or such other person or entity designated by the Required Banks, regardless of whether the Pledgor
was previously making collections thereon. The Agent shall promptly account to the Pledgor for all
such payments received by the Agent. Each Obligor making such payment to the Agent or such other
person or entity designated by the Required Banks shall be fully protected in relying on the
written statement of the Agent that the Pledgees then hold the security interests herein granted
and assigned which entitled the Agent or such other person or entity designated by the Required
Banks to receive such payment, and the receipt of the Agent or such other person or entity
designated by the Required Banks for such payment shall be full acquittance therefor to the Obligor
making such payment.

          Section 9. DEFAULTED LOANS; COLLECTION AND FORECLOSURE PROCEEDINGS.

          If the Pledgor wishes to institute collection or foreclosure proceedings with respect to a
Pledged Mortgage Loan, it shall substitute other Collateral so that it is entitled pursuant to the
terms of the Credit Agreement to a release of such Pledged Mortgage Loan. If the Pledgor does not
own sufficient other Collateral to obtain a release of such Pledged Mortgage Loan, then so long as
an Event of Default or an Unmatured Event of Default has not occurred and is continuing, the
Collateral Agent, upon written request of the Pledgor, will deliver, upon such

C-11

 

terms and conditions
as the Collateral Agent in its sole discretion may establish, to an attorney at law, as the agent
of the Collateral Agent and the Pledgees, to the extent necessary for the purpose of enabling said
attorney to institute, in the name of the Pledgor, the Collateral Agent, the Agent or the Pledgees,
or in their names or in the names of their nominees, as the Required Banks may determine,
collection and/or foreclosure proceedings on any Pledged Mortgage Loan in default the following:
(a) the promissory note or other instrument evidencing any such Pledged Mortgage Loan in default
and (b) the mortgage or deed of trust, if any, that secures such promissory note, or other
Collateral needed by said attorney in connection with such collection and/or foreclosure
proceedings in such manner and in such form as the Collateral Agent deems necessary or desirable to
preserve the Pledgees’ security interests in such Collateral, provided such Collateral and all
proceeds of any such collection and/or foreclosure efforts shall remain subject to this Pledge and
Security Agreement and the security interests granted herein and all such proceeds shall be
delivered to the Agent as and when and in the form received to the extent required by the terms of
the Credit Agreement. The Pledgor hereby covenants and agrees that, without first obtaining the
prior written consent of the Agent, it will not request or accept any
discount on, or any conveyance, endorsement, transfer or assignment of any right, title or
interest in and to any of the real, personal or mixed properties sold, pledged, mortgaged,
hypothecated, assigned, transferred, set over or conveyed to the Pledgees as security for, any of
the promissory notes or other instruments or agreements which evidence Pledged Mortgage Loans in
lieu of foreclosure proceedings if, after giving effect to any such proposed transaction, the
Borrowing Base would be less than the Aggregate Outstandings. At such time as such delivery of the
Collateral is no longer required in connection with said collection and/or foreclosure efforts, the
same shall be reassigned and redelivered to the Collateral Agent.

          Section 10. SALES AND RELEASES OF COLLATERAL.

          10.01 Redelivery of Collateral for Correction. If no Event of Default or Unmatured Event of
Default exists, the Collateral Agent may redeliver to the Pledgor, for correction, any instrument
or document which constitutes or relates to any of the Collateral; provided, that any such
redelivery shall be made against a Trust Receipt duly completed and executed by the Pledgor
requiring, within 20 days after the redelivery thereof to the Pledgor, the return to the Collateral
Agent of each such instrument and document. The Pledgor shall deliver to the Collateral Agent each
such instrument and document as soon as it has completed the correction thereof and, in any event,
within 20 days after its receipt thereof.

          10.02 Delivery for Sale of Pledged Mortgage Loans. If no Event of Default or Unmatured
Event of Default exists, the Pledgor may direct the Collateral Agent to, and the Collateral Agent
will, transmit on behalf of the Pledgor Pledged Mortgage Loans, accompanied by a duly completed and
executed Bailee Letter, to an Approved Investor who Pledgor has represented has issued a Loan
Specific Take-Out Commitment or Hedge or to a document custodian for such documents. All sale
proceeds transferred to the Agent pursuant to such Bailee Letter and all Mortgage Notes and other
documents returned to the Collateral Agent pursuant to such Bailee Letter shall remain a part of
the Collateral unless and until released pursuant to Section 10.04 of this Agreement. All Pledged
Mortgage Loans which are so transmitted or otherwise delivered but not paid for shall constitute
Collateral and shall, subject to the conditions and limitations contained in Exhibit A to the
Credit Agreement, be included in determining the Borrowing Base. The proceeds received by the
Agent from the sale of any Pledged Mortgage

C-12

 

Loans pursuant to this Section 10.02 shall be deposited
by the Collateral Agent in the Settlement Account and shall be promptly applied to the payment of
principal of the obligations as provided in the Credit Agreement, provided, however, if an Event of
Default has occurred and is continuing, such proceeds shall be applied in accordance with Section
17 hereof.

          10.03 Formation of Pools.

          (a) With respect to each Pledged Mortgage Loan which is intended for inclusion in a
pool of Mortgage Loans backing GNMA Securities, the Pledgor shall enter into and
conform with such custody and related agreements and procedures as are reasonably
required by the Collateral Agent, with the approval of the Agent, to permit the creation,
transmittal to, maintenance and sale of GNMA Securities in both certificated and
uncertificated book-entry form. The Collateral Agent may enter into such agreements as may
be necessary or appropriate in the sole discretion of the Collateral Agent, with the
approval of the Agent, in order to effectuate the issuance, maintenance and transfer of such
GNMA Securities under any such book-entry system or program.

          (b) With respect to each Pledged Mortgage Loan which is intended for inclusion in a
FNMA or FHLMC Mortgage Loan pool to back book-entry FNMA Securities or FHLMC Securities, the
Pledgor agrees that it will enter into and conform to such agreements and procedures as are
established by the Collateral Agent in its reasonable judgment, with the approval of the
Agent, from time to time for the delivery of Pledged Mortgage Loans to a FHLMC or FNMA pool
custodian (or directly to FHLMC or FNMA, as the case may be) and the issuance, maintenance
and transfer of FHLMC Securities or FNMA Securities under such book-entry system or program.
The Collateral Agent may enter into such agreements as may be necessary or appropriate in
the reasonable judgment of the Collateral Agent, with the approval of the Agent, in order to
effectuate the issuance, maintenance and transfer of such FNMA Securities or FHLMC
Securities under such book-entry system or program. The Pledgor further agrees that the
initial certifications and the settlements in connection with FNMA, FHLMC and GNMA pools are
to be performed by the Collateral Agent or its designated agent.

          (c) The Collateral Agent or its designated agent (which designated agent must be
pre-approved by the Agent) will use its best efforts to complete documents in a timely
manner and otherwise to cooperate with the Pledgor in the issuance of Mortgage-Backed
Securities and the formation of pools of Mortgage Loans as contemplated by this Section
10.03, and will cause all Mortgage Loans delivered to a pool custodian to be accompanied by
a Bailee Letter. The Collateral Agent and such designated agent shall be entitled to rely
on the written instructions of the Pledgor and shall have no obligation to act in the
absence of such written instructions or published guidelines.

          10.04 Release of Particular Collateral. (a) If no Event of Default or Unmatured Event of
Default has occurred and is continuing, the Collateral Agent on behalf of the Pledgees shall, at
the written request of the Pledgor, release their security interest in any item of Collateral
specified by the Pledgor in such written request, provided that, after giving effect to such
requested release, the Borrowing Base (including therein the Collateral Value of any Collateral
given in substitution for the Collateral to be released) shall not be less than the aggregate

C-13

 

principal amount under the Notes outstanding. If the Pledgor requests and is entitled to a release
of a Pledged Mortgage Loan pursuant to the preceding sentence, the Collateral Agent shall promptly
redeliver to the Pledgor the Mortgage Note evidencing such Pledged Mortgage Loan, with any previous
endorsement or assignment, without recourse upon or representation or warranty by the Collateral
Agent, the Agent or the Banks, of any part of the Collateral that secures such Mortgage Note.

          (b) Whether or not the Pledgor, by terms of this Section 10.04, is entitled to a release of
the Pledgees’ security interest in the Collateral, the Collateral Agent on behalf of the Pledgees
shall release such security interest in any Pledged Mortgage Loan to the extent necessary to permit
the Pledgor to execute any full or partial release of any mortgage, deed of trust, security
agreement, financing statement or other security instrument or deed which the Pledgor is
contractually obligated to release upon payment thereof, provided the Pledgor promptly remits such
payment directly to the Agent to the Settlement Account for application upon the unpaid obligations
as provided in the Credit Agreement, unless an Event of Default has occurred and it continuing, in
which case such payment shall be applied as provided in Section 17 hereof.

          (c) Upon the Agent’s receipt of the entire proceeds from the sale of a Pledged Mortgage Loan
delivered to an Investor pursuant to Section 10.02 hereof, the security interest of the Pledgees in
such Pledged Mortgage Loan and in the Mortgage Note and other documents related thereto shall
terminate without further action by the Collateral Agent, provided that (i) the Pledgees’ security
interest in the proceeds of such Pledged Mortgage Loan, Mortgage Note and other documents shall
continue in full force and effect, and (ii) the Collateral Agent shall be authorized to execute any
release required in order to obtain such proceeds.

          (d) Upon the receipt by the Agent of the entire proceeds from the sale of a Related
Mortgage-Backed Security representing an interest in, or which is secured by, Pledged Mortgage
Loans delivered pursuant to Section 10.03 hereof, the security interest of the Pledgees in such
Pledged Mortgage Loans shall terminate without further action by the Pledgees, provided that (i)
the Pledgees’ security interest in the proceeds of such Mortgage-Backed Security shall continue in
full force and effect, and (ii) the Collateral Agent shall be authorized to execute any release
required in order to obtain such proceeds.

          Section 11. FURTHER ASSURANCES.

          The Pledgor, upon the request of the Collateral Agent, the Agent or the Required Banks, will
promptly correct any patent defect, error or omission which may be discovered in the contents of
this Pledge and Security Agreement or in the execution hereof and
will do such further acts and
things, and execute, acknowledge, endorse and deliver such further instruments, agreements,
schedules and certificates, including, but not limited to, notes, mortgages, deeds of trust,
assignments, chattel mortgages, security agreements and financing statements covering the title to
any real, personal or mixed property now owned or hereafter acquired by the Pledgor and now or
hereafter constituting Collateral, schedules and certificates respecting all or any of the
Collateral at the time subject to the security interest hereunder, the items or amounts received by
the Pledgor in full or partial payment, or otherwise as proceeds of any of the Collateral and
supplements to and amendments of this Pledge and Security Agreement, that the Collateral Agent, the
Agent or the Required Banks may at any time and from time to time reasonably

C-14

 

request in connection
with the administration or enforcement of this Pledge and Security Agreement or related to the
Collateral or any part thereof or in order to assure and confirm unto the Collateral Agent, the
Agent and the Pledgees the rights, powers and remedies hereunder or to subject all of the real,
personal or mixed properties now owned or hereafter acquired by the Pledgor and now or hereafter
constituting Collateral to, or to confirm or clearly establish that all
of said properties are subject to and encumbered by, a lien to secure the due and punctual
payment of the Secured Obligations. Any such instrument, agreement, schedule or certificate shall
be executed by a duly authorized officer of the Pledgor and shall be in such form and detail as the
Collateral Agent, the Agent or the Required Banks may reasonably specify. Promptly upon the
request of the Collateral Agent or the Agent, the Pledgor will mark, or permit the Collateral Agent
to mark in a reasonable manner, the Pledgor’s books, records and accounts showing or dealing with
the Collateral with a notation clearly setting forth that the Collateral has been assigned to the
Pledgees, which notation shall be in form and substance satisfactory to the Collateral Agent.

          The Pledgor will do all acts and things, and will execute and file or record, and hereby
authorizes the Collateral Agent to file and record, all instruments (including mortgages, pledges,
assignments, security agreements, financing statements, amendments to financing statements,
continuation statements, etc.) required, or reasonably requested by the Collateral Agent, the Agent
or the Required Banks, to establish, perfect, maintain and continue the perfection and priority of
the security interest of the Pledgees in the Collateral and will pay the costs and expenses of:
all filings and recordings, including taxes thereon; all searches necessary, or reasonably deemed
necessary by the Collateral Agent, the Agent or the Required Banks, to establish and determine the
validity and the priority of such security interest of the Pledgees; and also to satisfy all other
liens which in the reasonable opinion of the Collateral Agent, the Agent or the Required Banks
might prejudice, imperil or otherwise affect the Collateral or the existence or priority of such
security interest. A carbon, photographic or other reproduction of this Pledge and Security
Agreement or of a financing statement shall be sufficient as a financing statement and may be filed
in lieu of the original in any or all jurisdictions which accept such reproductions.

          Section 12. COVENANTS OF THE PLEDGOR.

          So long as this Pledge and Security Agreement shall remain in effect, the Pledgor will (a)
defend the right, title and interest of the Pledgees in the Collateral against the claims and
demands of all Persons; (b) not amend, modify, or waive any of the terms and conditions of, or

adversely affect the interests of the Pledgees; (c) not sell, assign, transfer, or otherwise

appraisals, computer programs,
tapes, discs, cards, accounting records and other records, information and data, relating to the
Collateral and will give the Collateral Agent, the Agent and
the Pledgees written notice of the place where such records, information and data will be

          So long as this Agreement shall remain in effect, the Pledgor will (a) be a “Member” (as
defined in the MERS Agreements) of MERSCORP, (b) maintain the Electronic Tracking Agreement in full
force and effect and timely perform all of its obligations thereunder, (c) provide the Agent and

          Section 13. COLLATERAL AGENT APPOINTED ATTORNEY-IN-FACT.

          Effective upon the occurrence and continuation of an Event of Default, the Pledgor hereby
appoints the Collateral Agent the Pledgor’s attorney-in-fact, with full power of substitution, to
submit any Pledged Mortgage Loan or Related Mortgage-backed Security which constitutes Collateral
and related documents to a purchaser under a Loan Specific Take-Out Commitment or Hedge and for the
purpose of carrying out the provisions of this Pledge and Security Agreement and taking any action
and executing in the name of the Pledgor without recourse to the Pledgor any instrument, including,
but not limited to, the instruments described in Section 2 hereof, which the Collateral Agent may
deem necessary or advisable to accomplish the purpose hereof, which appointment is irrevocable and
coupled with an interest. Without limiting the generality of the foregoing, the Collateral Agent
shall have the right and power to receive, endorse and collect checks and other orders for the
payment of money made payable to the Pledgor representing any payment or reimbursement made under,
or pursuant or with respect to, the Collateral or any part thereof and to give full discharge for
the same. Whether or not an

C-16

 

Event of Default or an Unmatured Event of Default shall have occurred or be continuing, the
Pledgor hereby authorizes the Collateral Agent in its discretion at any time and from time to time
to (i) complete or cause to be completed any assignment of real estate mortgage or deed of trust
which heretofore was, or hereafter at any time may be, executed and delivered by the Pledgor to the
Collateral Agent so that such assignment describes a real estate mortgage or deed of trust which is
security for any Pledged Mortgage Loan now or hereafter at any time constituting Collateral and
(ii) complete or cause to be completed any other assignment or endorsement that was delivered in
blank hereunder.

          Section 14. EVENTS OF DEFAULT: REMEDIES.

          If one or more Events of Default shall occur, then the Required Banks, in addition to any and
all other rights and remedies which the Collateral Agent, the Agent, the Pledgees or the Required
Banks may then have hereunder, under the Credit Agreement, under the Uniform Commercial Code of the
State of Minnesota or of any other pertinent jurisdiction (the “Code”), or under any other
instrument, or which the Collateral Agent, the Agent, the Pledgees or the Required Banks may have
at law or in equity, or otherwise, may, at their option, direct the Agent or the Collateral Agent
to (a) in the name of the Pledgor, or otherwise, demand, collect, receive and receipt for,
compound, compromise, settle and give acquittance for, and prosecute and discontinue any suits or
proceedings in respect of any or all of the Collateral; (b) take any action which the Required
Banks may deem necessary or desirable in order to realize on the Collateral, including, without
limitation, the power to perform any contract, endorse in the name of the Pledgor without recourse
to the Pledgor any checks, drafts, notes or other instruments or documents received in payment of
or on account of the Collateral; (c) enter upon the premises where any of the Collateral not in the
possession of the Agent or the Collateral Agent is located and take possession thereof and remove
the same, with or without judicial process; (d) reduce the claims of the Pledgees to judgment or
foreclosure or otherwise enforce the security interests herein granted and assigned, in whole or in
part, by any available judicial procedure; (e) after notification, if any, provided for herein,
sell, lease, or otherwise dispose of, at the office of the Agent or the Collateral Agent, on the
premises of the Pledgor, or elsewhere, all or any part of the Collateral, in its then condition or
following any commercially reasonable preparation or processing, and any such sale or other
disposition may be as a unit or in parcels, by public or private proceedings, and by way of one or
more contracts (it being agreed that the sale of any part of Collateral shall not exhaust the power
of sale granted hereby, but sales may be made from time to time, and at any time, until all the
Collateral has been sold or until all Secured Obligations have been fully paid and performed), and
at any such sale it shall not be necessary to exhibit any of the Collateral; (f) at its discretion,
surrender any policies of insurance on the Collateral consisting of real or personal property owned
by the Pledgor and receive the unearned premiums, and, in connection therewith, the Pledgor hereby
appoints the Agent as the agent and attorney-in-fact for the Pledgor to collect such premiums; (g)
at its discretion, retain the Collateral in satisfaction of the Secured Obligations whenever the
circumstances are such that the Pledgees are entitled to do so under the Code or otherwise; and (h)
exercise any and all other rights, remedies and privileges which the Collateral Agent, the Agent,
the Pledgees or the Required Banks may have under this Pledge and Security Agreement, or any of the
other promissory notes, assignments, mortgages, deeds of trust, chattel mortgages, security
agreements, transfers of lien, and any other instruments, documents, and agreements executed
and delivered pursuant to the terms hereof or pursuant to the terms of the Credit Agreement. The

C-17

 

Pledgor acknowledges and agrees that (x) a private sale of the Collateral pursuant to any Loan
Specific Take-Out Commitment or Hedge shall be deemed to be a sale of the Collateral in a
commercially reasonable manner and (y) the Collateral is intended to be sold and that none of the
Collateral is a type or kind intended by the Pledgor to be held for investment or any purpose other
than for sale.

          Section 15. WAIVERS.

          The Pledgor, for itself and all who may claim under the Pledgor, as far as the Pledgor now or
hereafter lawfully may, also waives all right to have all or any portion of the Collateral
marshalled upon any foreclosure hereof and agrees that any court having jurisdiction over this
Pledge and Security Agreement may order the sale of all or any portion of the Collateral as a
single block. Any sale of, or the grant of options to purchase (for the option period thereof or
after exercise thereof), or any other realization upon, all or any portion of the Collateral under
clause (e) of Section 14 shall operate to divest all right, title, interest, claim and demand,
either at law or in equity, of the Pledgor in and to the Collateral so sold, optioned or realized
upon, and shall be a perpetual bar both at law and in equity against the Pledgor and against any
and all persons claiming or attempting to claim the Collateral so sold, optioned or realized upon
or any part thereof, from, through and under the Pledgor. No delay on the part of the Collateral
Agent, the Agent, the Pledgees or the Required Banks in exercising any power of sale, lien, option
or other right hereunder and no notice or demand which may be given to or made upon the Pledgor
with respect to any power of sale, lien, option or right hereunder shall constitute a waiver
thereof, or limit or impair the right of the Collateral Agent, the Agent, the Pledgees or the
Required Banks to take any action or to exercise any power of sale, lien, option or any other right
under this Pledge and Security Agreement or the Credit Agreement, or otherwise, nor shall any
single or partial exercise thereof, or the exercise of any power, lien, option or other right under
this Pledge and Security Agreement or otherwise, all without notice or demand (except as otherwise
provided by the terms of this Pledge and Security Agreement), prejudice their rights against the
Pledgor in any respect. Each and every remedy given the Collateral Agent, the Agent, the Pledgees
or the Required Banks shall, to the extent permitted by law, be cumulative and shall be in addition
to any other remedy given hereunder or now or hereafter existing at law or in equity or by statute.

          Section 16. NOTICES.

          Reasonable notification of the time and place of any public sale of any Collateral, or
reasonable notification of the time after which any private sale or other intended disposition of
any of the Collateral is to be made shall be sent to the Pledgor and
to any other person entitled under the Code to notice; provided, that if any of the Collateral threatens to decline speedily in
value, or is of a type customarily sold on a recognized market, the Collateral Agent, at the
direction of the Required Banks, may sell or otherwise dispose of the Collateral without
notification, advertisement, or other notice of any kind. It is agreed that notice sent or
given not less than fifteen (15) calendar days prior to the taking of the action to which the
notice relates is reasonable notification and that such notice is sufficient if it states only the
number of Pledged Mortgage Loans to be sold and their aggregate outstanding principal balance,
together with the time and place of sale. All notices and other communications provided for in the
Pledge and Security Agreement shall be given to the parties at their respective addresses set forth
on the

C-18

 

signature pages to this Pledge and Security Agreement or, as to each such party, at such
other address as shall be designated by such party in a written notice to the other parties. All
such notices and other communications shall be given by one or more of the means specified in
Section 8.02 of the Credit Agreement and, upon being so given, shall be deemed to have been given
as of the earliest time specified in said Section 8.02 for the means so used.

          Section 17. APPLICATION OF PROCEEDS.

          Until all Secured Obligations owed to the Pledgees have been paid in full, any and all
proceeds ever received by the Agent or the Collateral Agent from any sale or other disposition of
the Collateral, or any part thereof, upon the occurrence of an Event of Default or the exercise of
any other remedy pursuant to Section 8 hereof or by virtue of Section 14 hereof, shall be applied
in accordance with following order of priority:

          First, to the payment of the out-of-pocket expenses of the Collateral Agent, the Agent and the
Pledgees and the reasonable fees and out-of-pocket expenses of counsel employed in connection
therewith, and to the payment of all costs and expenses incurred by the Collateral Agent, the Agent
and the Pledgees in connection with the administration and enforcement of this Pledge and Security
Agreement (including, without limitation, the sale or other disposition of the Collateral) and to
the payment of all advances made by the Collateral Agent, the Agent and the Pledgees for the
account of the Pledgor hereunder, to the extent that such costs and expense have not been
reimbursed to the Collateral Agent, the Agent or the Pledgees, as the case may be;

          Second: to the payment in full of the remaining Secured Obligations; and

          Third: the balance (if any) of such proceeds shall be paid to the Pledgor, its successors or
assigns, or as a court of competent jurisdiction may direct, provided, that if such proceeds are
not sufficient to satisfy the Secured Obligations in full, the Pledgor shall remain liable to the
Pledgees for any deficiency.

          Section 18. INDEMNIFICATION AND COSTS AND EXPENSES.

          The Pledgor will (a) pay all reasonable out-of-pocket expenses, including, without limitation,
any recording or filing fees, fees of title insurance companies in connection with records or
filings, costs of mortgage insurance policies and endorsements thereof and mortgage registration
taxes (or any similar fees or taxes), incurred by the Collateral Agent, the Agent and the Pledgees
in connection with the enforcement and administration of this Pledge and Security Agreement
(whether or not the transactions hereby contemplated shall be
consummated) and the Credit Agreement, the enforcement of the rights of the Collateral Agent, the Agent and the
Pledgees in connection with this Pledge and Security Agreement and the Credit Agreement and
including, without limitation, the reasonable fees and disbursements of counsel for the Collateral
Agent, the Agent and the Pledgees; (b) pay, and hold the Collateral Agent, the Agent and the
Pledgees harmless from and against, any and all present and future stamp and other similar taxes
with respect to the foregoing matters and save the Collateral Agent, the Agent and the Pledgees
harmless from and against any and all liabilities with respect to or resulting from any delay or
omission to pay such taxes; and (c) indemnify, pay and hold harmless the Collateral Agent, the
Agent and the Pledgees from and against any and all liabilities, obligations, losses, damages,

C-19

 

penalties, judgments, suits, costs, expenses and disbursements of any kind whatsoever (the
“Indemnified Liabilities”) which may be imposed on, incurred by or asserted against it in any way
relating to or arising out of this Pledge and Security Agreement or the Credit Agreement or any of
the transactions contemplated hereby or thereby, unless the same are caused by the gross negligence
or willful misconduct of the Collateral Agent, the Agent or the Pledgees, as the case may be. The
undertakings of the Pledgor set forth in this Section 18 shall survive the payment in full of the
Notes and the termination of this Pledge and Security Agreement and the Credit Agreement.

          Section 19. TERMINATION.

          This Pledge and Security Agreement shall terminate when all the Secured Obligations have been
fully paid and performed, at which time the Collateral Agent shall reassign and redeliver, without
recourse upon, or representation or warranty by, the Collateral Agent and at the expense of the
Pledgor, to the Pledgor, or to such other person or persons as the Pledgor shall designate, against
receipt, such of the Collateral (if any) as shall not have been sold or otherwise disposed of by
the Agent, the Collateral Agent or the Pledgees, pursuant to the terms hereof or the Credit
Agreement, and shall still be held by the Collateral Agent, together with appropriate instruments
of reassignment and release.

          Section 20. NON-ASSUMPTION OF LIABILITY; NO FIDUCIARY RESPONSIBILITY.

          Nothing herein contained shall relieve the Pledgor from performing any covenant, agreement or
obligation on the part of the Pledgor to be performed under or in respect of any of the Collateral
or from any liability to any party or parties having an interest therein or impose any liability on
the Collateral Agent, the Agent or the Pledgees for the acts or omissions of the Pledgor in
connection with any of the Collateral. The Collateral Agent, the Agent and the Pledgees shall not
assume or become liable for, nor shall it be deemed or construed to have assumed or become liable
for, any obligation of the Pledgor with respect to any of the Collateral, or otherwise, by reason
of the grant to the Pledgees of security interests in the Collateral. While the Collateral Agent
shall use reasonable care in the custody and preservation of the Collateral as provided in Section
6 hereof, the Collateral Agent shall not have any fiduciary responsibility to
the Pledgor with respect to the holding, maintenance or transmittal of the Collateral
delivered hereunder.

          Section 21. CONCERNING THE COLLATERAL AGENT.

          21.01 Appointment and Authorization. Each Bank has under the Credit Agreement, appointed
and authorized U.S. Bank National Association to act as Collateral Agent under this Pledge and
Security Agreement and has authorized the Collateral Agent to take such action as agent on its
behalf and to exercise such powers under this Pledge and Security Agreement as are delegated to the
Collateral Agent by the terms hereof, together with such powers as are reasonably incidental
thereto. As to any matters not expressly provided for by this Pledge and Security Agreement,
neither the Collateral Agent, its affiliates nor any of their respective directors, officers,
agents or employees shall be liable for any action taken or omitted to be taken by it or them
hereunder, except for its or their own gross negligence or willful misconduct;

C-20

 

provided, the
Collateral Agent shall be fully protected in acting or refraining from acting or refraining from
acting upon the instructions of the Required Banks; provided, further, that the Collateral Agent
shall not be required to take any action which exposes it to personal liability or is contrary to
any Loan Document or applicable law. The Collateral Agent shall act as agent for and on behalf of
the Banks in performing its obligations as Collateral Agent hereunder and nothing herein contained
shall be deemed to create a fiduciary relationship between the Collateral Agent and the Pledgor,
between the Agent and the Pledgor or between any Bank and the Pledgor.

          21.02 Duties Of The Collateral Agent. The Collateral Agent shall have the following
responsibilities with regard to the Collateral and the related Collateral Documents delivered to
the Collateral Agent by the Pledgor under Section 4 hereof: The Collateral Agent shall deliver to
the Pledgor and the Agent:

          (a) by 1:30 p.m. (Denver time) on each Business Day, a Borrowing Base report in a form
reasonably acceptable to the Agent via facsimile, which report shall reflect the status and
amount of the Eligible Mortgage Loans calculated as of 12:30 p.m. (Denver time) on the date
of preparation of such report;

          (b) on the last Business Day of each calendar week, via overnight courier or electronic
mail, (i) a report of the Pledged Mortgage Loans (noting any document exceptions) for the
week ended (a “Basic Status Report”), (ii) a report of the Pledged Mortgage Loans shipped to
Approved Investors for which the Collateral Agent has not received the full purchase price
in cash (a “Shipped Not Paid Report”), and (iii) a report of the Pledged Mortgage Loans
under Trust Receipt (a “Trust Release Report”), each such report to be in a form supplied by
the Collateral Agent;

          (c) by 10:00 a.m. (Denver time) on each Business Day, via facsimile a report of the
Eligible Mortgage Loans that will become ineligible for inclusion in the computation
of the Collateral Value of the Borrowing Base on each such Business Day (an “Ineligible
Collateral Report”) in a form reasonably acceptable to the Agent; and

          (d) from time to time, such other reports and information as the Agent may from time to
time reasonably request. In preparing any such reports the Collateral Agent shall be
entitled to rely, without independent investigation, on information supplied to the
Collateral Agent by the Pledgor and the Agent.

          21.03 Possession Of Collateral; Standard Of Care. The Collateral Agent shall maintain the
Collateral at its offices located at the address indicated on the signature page hereof. The
Collateral Agent shall segregate the Collateral from all other mortgages, mortgage notes and other
documents and instruments similar in nature to the Collateral in its possession and shall mark and
hold the Collateral in its possession so as to reflect the ownership by the Pledgor and the
security interest of the Pledgees therein. The Collateral Agent shall exercise reasonable care in
the custody and preservation of the Collateral. As among the Collateral Agent and the Banks, the
Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation
of any of the Collateral in its possession if it takes such action for that purpose as Pledgor or
the Required Banks request in writing, but failure of the Collateral Agent to comply

C-21

 

with any such
request shall not itself be deemed a failure to exercise reasonable care, and no failure of the
Collateral Agent to preserve or protect any rights with respect to such Collateral not so requested
by Pledgor or the Required Banks shall be deemed a failure to exercise reasonable care in the
custody or preservation of such Collateral. The Collateral Agent shall also be deemed to have
exercised reasonable care in the safekeeping of any Collateral in its possession if such Collateral
is accorded treatment substantially equal to the safekeeping which the Collateral Agent accords to
its own property of like kind.

          21.04 Limitations on Responsibility of Collateral Agent. The Collateral Agent shall not be
responsible in any manner whatsoever for the correctness of any recitals, statements,
representations or warranties contained herein, except for those made by it herein. The Collateral
Agent makes no representation as to the value or condition of the Collateral or any part thereof,
as to the title of the Pledgor to the Collateral, as to the security afforded by this Pledge and
Security Agreement or the related Security Documents or as to the validity, enforceability,
legality or sufficiency of this Pledge and Security Agreement or the related Security Documents,
and the Collateral Agent shall incur no liability or responsibility in respect of any such matters.
The Collateral Agent shall not be responsible for insuring the Collateral, for the payment of
taxes, charges, assessments or liens upon the Collateral or otherwise as to the maintenance of the
Collateral, except as provided in the immediately following sentence when the Collateral Agent has
possession of the Collateral. The Collateral Agent shall have no duty to the Pledgor as to any
Collateral in its possession or control or in the possession or control of any agent or nominee of
the Collateral Agent or any Collections thereon or Proceeds thereof or as to the preservation of
rights against prior parties or any other rights pertaining thereto, except the duty to accord such
of the Collateral as may be in its possession substantially the same care as it accords its own
assets and the duty to account for monies received by it and, notwithstanding the foregoing, the
duty not to engage in wilful
misconduct or gross negligence with respect to Collateral in its possession. Except as
expressly set forth herein, the Collateral Agent shall not be required to ascertain or inquire as
to the performance by the Pledgor of any of the covenants or agreements contained herein or in the
related Security Documents. Neither the Collateral Agent nor any officer, agent or representative
thereof shall be personally liable for any action taken or omitted to be taken by any such person
in connection with this Pledge and Security Agreement or any related Security Document except for
such person’s own gross negligence or wilful misconduct; provided, however, neither the Collateral
Agent nor any officer, agent or representative thereof shall be personally liable for any action
taken by any such person in accordance with any notice given by the Required Banks hereunder. The
Collateral Agent may execute any of the powers granted under this Pledge and Security Agreement or
any of the related Security Documents and perform any duty hereunder or thereunder either directly
or by or through agents or attorneys-in-fact, and shall not be responsible for the negligence or
misconduct of any agents or attorneys-in-fact selected by it without gross negligence or wilful
misconduct.

          21.05 Reliance by Collateral Agent; Indemnity Against Liabilities; etc.

          (a) Whenever in the performance of its duties under this Pledge and Security Agreement
the Collateral Agent shall deem it necessary or desirable that a matter be proved or
established with respect to the Pledgor or other person in connection with the taking,
suffering or omitting of any action hereunder by the Collateral Agent, such matter

C-22

 

may be
conclusively deemed to be proved or established by a certificate executed by an officer of
such person, and the Collateral Agent shall have no liability with respect to any action
taken, suffered or omitted in reliance thereon.

          (b) The Collateral Agent may consult with counsel and shall be fully protected in
taking any action hereunder in accordance with any advice of such counsel. The Collateral
Agent shall have the right but not the obligation at any time to seek instructions
concerning the administration of this Pledge and Security Agreement, the duties created
hereunder or the Collateral from any court of competent jurisdiction.

          (c) The Collateral Agent shall be fully protected in relying upon any resolution,
statement, certificate, instrument, opinion, report, notice, request, consent, order or
other paper or document which it reasonably believes to be genuine and to have been signed
or presented by the proper party or parties. In the absence of its gross negligence or
wilful misconduct, the Collateral Agent may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon any certificate or
opinions furnished to the Collateral Agent in connection with this Pledge and Security
Agreement.

          (d) The Collateral Agent shall not be deemed to have actual, constructive, direct or
indirect notice or knowledge of the occurrence of any Event of Default or Unmatured Event of
Default unless and until the Collateral Agent shall have received a notice of such Event of
Default or Unmatured Event of Default. The Collateral Agent shall have no obligation
whatsoever either prior to or after receiving such a notice to inquire whether an Event of
Default or Unmatured Event of Default has, in fact, occurred and
shall be entitled to rely conclusively, and shall be fully protected in so relying, on
any notice so furnished to it so long as such notice is received from the Pledgor, the Agent
or the Required Banks. The Collateral Agent may (but shall not be obligated to) take action
hereunder on the basis of an Event of Default or Unmatured Event of Default of the type
specified in Section 6.01(h) or Section 6.01(i) of the Credit Agreement whether or not the
Collateral Agent has received any notice of such Event of Default.

          (e) If the Collateral Agent has been requested to take any specific action pursuant to
any provision of this Pledge and Security Agreement, the Collateral Agent shall not be under
any obligation to exercise any of the rights or powers vested in it by this Pledge and
Security Agreement in the manner so requested unless it shall have been provided an
indemnity satisfactory to it against the costs, expenses and liabilities which may be
incurred by it in compliance with such request or direction.

          21.06 Resignation and Removal of the Collateral Agent. (a) The Collateral Agent may resign
at any time by giving 30 days written notice thereof to the Pledgor, the Agent and the Banks. Upon
any such resignation, the Required Banks shall have the right to appoint a successor Collateral
Agent, which successor Collateral Agent shall (unless an Event of Default has then occurred and is
continuing) be reasonably acceptable to the Pledgor. If no successor Collateral Agent shall have
been so appointed and shall have accepted such appointment within 30 days after the retiring
Collateral Agent’s giving notice of its resignation, then the retiring Collateral Agent may, on
behalf of the Banks, appoint a Collateral Agent, which shall be a Bank or a commercial bank
organized under the laws of the United States of America or of any State

thereof and having a
combined capital and surplus of at least $100,000,000 or an affiliate of any such bank, and which
shall be reasonably acceptable to the Pledgor (unless an Event of Default has occurred and is
continuing). Any such resignation shall be effective upon the appointment of a successor
Collateral Agent. Upon the acceptance of any appointment as the Collateral Agent hereunder by a
successor Collateral Agent, such successor Collateral Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Collateral Agent, and the
retiring Collateral Agent shall be discharged from its duties and obligations, under this Agreement
and the other Loan Documents.

          (b) The Collateral Agent may be removed at any time, with or without cause, upon written
notice from the Required Banks, and the Collateral Agent may be removed upon written notice from
any Bank (a copy of which notice shall also be provided to the Agent and each other Bank) if the
Collateral Agent is placed in receivership or conservatorship or ceases to be eligible to serve as
a depository or document custodian on behalf of FNMA, FHLMC or GNMA. Upon any such removal, the
Required Banks shall have the right to appoint a successor Collateral Agent.

          21.07 Indemnification by Pledgor. The Pledgor hereby indemnifies and holds harmless the
Collateral Agent and its directors, officers, employees and agents, on demand, from and against any
and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or
asserted against the Collateral Agent in its capacity as the Collateral Agent or any of them
in any way relating to or arising out of this Pledge and Security Agreement or any related Loan
Document or any action taken or omitted by them under this Pledge and Security Agreement or any
related Loan Document; provided, that the Pledgor shall not be liable to the Collateral Agent for
any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the gross negligence or wilful misconduct of
the Collateral Agent or any of its directors, officers, employees or agents.

          21.08 Expenses and Indemnification by the Banks. The Banks, by execution of the Credit
Agreement, have agreed (a) to reimburse the Collateral Agent, on demand, for any expenses referred
to in Section 18 hereof which shall not have been reimbursed by the Pledgor or paid from the
proceeds of Collateral as provided herein and (b) to indemnify and hold harmless the Collateral
Agent and its directors, officers, employees and agents, on demand, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements referred to in Section 18 hereof, to the extent the same shall not have been
reimbursed by the Pledgor or paid from the proceeds of Collateral as provided herein; provided,
that the Banks shall not be liable to the Collateral Agent for any
portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the gross negligence or wilful misconduct of the Collateral Agent or
any of its directors, officers, employees or agents.

          21.09 Collateral Agent Compensation. The Pledgor shall pay all fees and other amounts to be
paid as compensation to the Collateral Agent as from time to time agreed upon by the Pledgor and
the Collateral Agent; the initial schedule of compensation is as provided in the Agent’s Side
Letter.

C-24

 

          21.10 Access To Collateral Agent’s Premises and Records. At all reasonable times and as
often as the Agent or any Bank may reasonably request, the Collateral Agent shall permit the Agent
or such Bank’s duly authorized representatives, attorneys or auditors, or their designees, to (a)
have access to the Collateral and the books and records of the Collateral Agent relating to the
Collateral, (b) make copies of, or excerpts from, the Collateral or the Collateral Agent’s books
and records and (c) observe the Collateral Agent’s procedures with respect to the Collateral and to
discuss those procedures or its books and records with any of the Collateral Agent’s employees, all
as shall be relevant to the performance or observance of the terms and provisions of this Pledge
and Security Agreement. Upon reasonable notice, the Pledgor shall have access to such books and
records relating to the Collateral, and to make copies from the same, at the Pledgor’s sole cost
and expense.

          Section 22. GOVERNING LAW.

          This Pledge and Security Agreement shall be a contract made under and governed by the law of
the State of Minnesota, without giving effect to conflict of laws principles thereof.

          Section 23. AMENDMENT.

          This Pledge and Security Agreement may be amended by an instrument in writing signed by the
Pledgor, the Agent and the Collateral Agent.

          Section 24. COUNTERPARTS; EFFECTIVENESS.

          This Pledge and Security Agreement and any amendments, waivers, consents, or supplements may
be executed in any number of counterparts, and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed to be an original, but
all such counterparts together shall constitute but one and the same instrument.

          Section 25. ENTIRE AGREEMENT.

          THIS AGREEMENT AND ALL LOAN DOCUMENTS EMBODY THE FINAL, ENTIRE AGREEMENT AMONG THE PARTIES
HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS AND UNDERSTANDINGS,
WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF, AND MAY NOT BE CONTRADICTED OR
VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS OF THE
PARTIES HERETO.

EXHIBIT 10.1

DIRECTOR RETIREMENT PLAN

DISTRIBUTION ELECTION FORM

SECTION I — PERSONAL DATA

NAME__________________________________

SECTION II — DISTRIBUTION ELECTION

If I cease to be a director of ABM Industries Incorporated at or after age 72, please distribute my
Director Retirement Plan benefits according to the following option (choose one):

o      Lump sum discounted payment

o      Annual installments for 10 years

I understand that if I cease to be a director prior to age 72, my retirement plan benefits will be
paid in annual installments beginning at age 65. If I die while serving as a director or prior to
beginning payments under the Director Retirement Plan, I will receive no benefits from the Director
Retirement Plan. I further acknowledge, that if I die while receiving annual installments, my
estate and beneficiaries will receive no additional payments under the Director Retirement Plan.

SECTION III — SIGNATURE

I acknowledge that my election (or change in election) is subject to the terms and conditions of
the Director Retirement Plan. If I file a subsequent election, then I understand it will not take
effect unless I retire more than one year after making such election and if I elect a lump sum
discounted payment, the earliest that I may receive such payment is five years following the date
of the subsequent election.

IMPORTANT TAX NOTICE

It is intended that benefits from the Plan are generally taxable when you actually receive them.
You cannot “roll over” the benefits into an Individual Retirement Account (IRA) or into a qualified
pension or profit sharing plan. Please contact your tax advisor because you may need to file
estimated tax payments.
