  Initial Exercise Date: October 27, 2009

    

     

    THIS
COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies
that, for value received, _____________ (the “Holder”) is entitled,
upon the terms and subject to the limitations on exercise and the conditions
hereinafter set forth, at any time on or after the date hereof (the “Initial Exercise
Date”) and on or prior to the close of business on the five year
anniversary of the Initial Exercise Date (the “Termination Date”)
but not thereafter, to subscribe for and purchase from Evergreen Energy Inc., a
Delaware corporation (the “Company”), up to
______ shares (the “Warrant Shares”) of
Common Stock.  The purchase price of one share of Common Stock under
this Warrant shall be equal to the Exercise Price, as defined in Section
2(b).

     

    Section
1.          Definitions.  Capitalized
terms used and not otherwise defined herein shall have the meanings set forth in
that certain Securities Purchase Agreement (the “Purchase Agreement”),
dated October 21, 2009, among the Company and the purchasers signatory
thereto.

     

    Section
2.           Exercise.

     

    a)           Exercise of
Warrant.  Exercise of the purchase rights represented by this
Warrant may be made, in whole or in part, at any time or times on or after the
Initial Exercise Date and on or before the Termination Date by delivery to the
Company (or such other office or agency of the Company as it may designate by
notice in writing to

    the
registered Holder at the address of the Holder appearing on the books of the
Company) of a duly executed facsimile copy of the Notice of Exercise Form
annexed hereto; and, within five (5) Trading Days of the date said Notice of
Exercise is delivered to the Company, the Company shall have
received  payment of the aggregate Exercise Price of the shares
thereby purchased by wire transfer or cashier’s check drawn on a United States
bank or, if available, pursuant to the cashless exercise procedure specified in
Section 2(c) below.  Notwithstanding anything herein to the contrary,
the Holder shall not be required to physically surrender this Warrant to the
Company until the Holder has purchased all of the Warrant Shares available
hereunder and the Warrant has been exercised in full, in which case, the Holder
shall surrender this Warrant to the Company for cancellation within five (5)
Trading Days of the date the final Notice of Exercise is delivered to the
Company.  Partial exercises of this Warrant resulting in purchases of
a portion of the total number of Warrant Shares available hereunder shall have
the effect of lowering the outstanding number of Warrant Shares purchasable
hereunder in an amount equal to the applicable number of Warrant Shares
purchased.  The Holder and the Company shall maintain records showing
the number of Warrant Shares purchased and the date of such
purchases.  The Company shall deliver any objection to any Notice of
Exercise Form within 1 Business Day of receipt of such notice.  The Holder and any assignee, by
acceptance of this Warrant, acknowledge and agree that, by reason of the
provisions of this paragraph, following the purchase of a portion of the Warrant
Shares hereunder, the number of Warrant Shares available for purchase hereunder
at any given time may be less than the amount stated on the face
hereof.

     

    b)           Exercise
Price.  The exercise price per share of the Common Stock under
this Warrant shall be $0.6480, subject to adjustment
hereunder (the “Exercise
Price”).

     

    c)           Cashless
Exercise.  If at any time after the earlier of (i) the one year
anniversary of the date of the Purchase Agreement and (ii) the completion of the
then-applicable holding period required by Rule 144, or any successor provision
then in effect, there is no effective Registration Statement registering, or no
current prospectus available for, the resale of the Warrant Shares by the
Holder, then this Warrant may also be exercised, in whole or in part, at such
time by means of a “cashless exercise” in which the Holder shall be entitled to
receive a certificate for the number of Warrant Shares equal to the quotient
obtained by dividing [(A-B) (X)] by (A), where:

     

    
      	
               
      

            	
              (A)
      = the VWAP on the Trading Day immediately preceding the date on which
      Holder elects to exercise this Warrant by means of a “cashless exercise,”
      as set forth in the applicable Notice of
  Exercise;

            

    

    

    
      	
               
      

            	
              (B)
      = the Exercise Price of this Warrant, as adjusted hereunder;
      and

            

    

     

    
      

      
        	
                 
      

              	
                      
                  (X)
      = the number of Warrant Shares that would be issuable upon exercise of
      this Warrant in accordance with the terms of this Warrant if such exercise
      were by means of a cash exercise rather than a cashless exercise, or if
      only a portion of this Warrant is being exercised, the portion of the
      Warrant being exercised (at the date of such
      calculation).

              Mechanics of
      Exercise.

      i.          Delivery of Certificates
Upon Exercise.  Certificates for shares purchased hereunder
shall be transmitted by the Transfer Agent to the Holder by crediting the
account of the Holder’s prime broker with the Depository Trust Company through
its Deposit Withdrawal Agent Commission (“DWAC”) system if the
Company is then a participant in such system and either (A) there is an
effective Registration Statement permitting the issuance of the Warrant Shares
to or resale of the Warrant Shares by the Holder or (B) the shares are eligible
for resale by the Holder without volume or manner-of-sale limitations pursuant
to Rule 144, and otherwise by physical delivery to the address specified by the
Holder in the Notice of Exercise by the date that is three (3) Trading Days
after the latest of (A) the delivery to the Company of the Notice of Exercise
Form, (B) surrender of this Warrant (if required), and (C) payment of the
aggregate Exercise Price as set forth above (including by cashless exercise, if
permitted) (such date, the “Warrant Share Delivery
Date”).  This Warrant shall be deemed to have been exercised on
the first date on which all of the foregoing have been delivered to the
Company.  The Warrant Shares shall be deemed to have been issued, and
Holder or any other person so designated to be named therein shall be deemed to
have become a holder of record of such shares for all purposes, as of the date
the Warrant has been exercised, with payment to the Company of the Exercise
Price (or by cashless exercise, if permitted) and all taxes required to be paid
by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of
such shares, having been paid.  If the Company fails for any reason to
deliver to the Holder certificates evidencing the Warrant Shares subject to a
Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to
the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000
of Warrant Shares subject to such exercise (based on the VWAP of the Common
Stock on the date of the applicable Notice of Exercise), $10 per Trading Day
(increasing to $20 per Trading Day on the fifth Trading Day after such
liquidated damages begin to accrue) for each Trading Day after such Warrant
Share Delivery Date until such certificates are delivered or Holder rescinds
such exercise.

       

    

    ii.          Delivery of New Warrants
Upon Exercise.  If this Warrant shall have been exercised in
part, the Company shall, at the request of a Holder and upon surrender of this
Warrant certificate, at the time of delivery of the certificate or certificates
representing Warrant Shares, deliver to Holder a new Warrant evidencing the
rights of Holder to purchase the unpurchased Warrant Shares called for by this
Warrant, which new Warrant shall in all other respects be identical with this
Warrant.

     

    iii.          Rescission
Rights.  If the Company fails to cause the Transfer Agent to
transmit to the Holder a certificate or the certificates representing the
Warrant Shares pursuant to Section 2(d)(i) by the 

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

    Warrant
Share Delivery Date, then, the Holder will have the right to rescind such
exercise.

     

    iv.         Compensation for Buy-In on
Failure to Timely Deliver Certificates Upon Exercise.  In
addition to any other rights available to the Holder, if the Company fails to
cause the Transfer Agent to transmit to the Holder a certificate or the
certificates representing the Warrant Shares pursuant to an exercise on or
before the Warrant Share Delivery Date, and if after such date the Holder is
required by its broker to purchase (in an open market transaction or otherwise)
or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to
deliver in satisfaction of a sale by the Holder of the Warrant Shares which the
Holder anticipated receiving upon such exercise (a “Buy-In”), then the
Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the
Holder’s total purchase price (including brokerage commissions, if any) for the
shares of Common Stock so purchased exceeds (y) the amount obtained by
multiplying (1) the number of Warrant Shares that the Company was required to
deliver to the Holder in connection with the exercise at issue times (2) the
price at which the sell order giving rise to such purchase obligation was
executed, and (B) at the option of the Holder, either reinstate the portion of
the Warrant and equivalent number of Warrant Shares for which such exercise was
not honored (in which case such exercise shall be deemed rescinded) or deliver
to the Holder the number of shares of Common Stock that would have been issued
had the Company timely complied with its exercise and delivery obligations
hereunder.  For example, if the Holder purchases Common Stock having a
total purchase price of $11,000 to cover a Buy-In with respect to an attempted
exercise of shares of Common Stock with an aggregate sale price giving rise to
such purchase obligation of $10,000, under clause (A) of the immediately
preceding sentence the Company shall be required to pay the Holder $1,000. The
Holder shall provide the Company written notice indicating the amounts payable
to the Holder in respect of the Buy-In and, upon request of the Company,
evidence of the amount of such loss.  Nothing herein shall limit a
Holder’s right to pursue any other remedies available to it hereunder, at law or
in equity including, without limitation, a decree of specific performance and/or
injunctive relief with respect to the Company’s failure to timely deliver
certificates representing shares of Common Stock upon exercise of the Warrant as
required pursuant to the terms hereof.

     

    v.         No Fractional Shares or
Scrip.  No fractional shares or scrip representing fractional
shares shall be issued upon the exercise of this Warrant.  As to any
fraction of a share which the Holder would otherwise be entitled to purchase
upon such exercise, the Company shall, at its election, either pay a cash
adjustment in respect of such final 

     

    
      
         

      

      
        4

        
          

        

      

      
         

      

    

    fraction
in an amount equal to such fraction multiplied by the Exercise Price or round up
to the next whole share.

     

    vi.         Charges, Taxes and
Expenses.  Issuance of certificates for Warrant Shares shall be
made without charge to the Holder for any issue or transfer tax or other
incidental expense in respect of the issuance of such certificate, all of which
taxes and expenses shall be paid by the Company, and such certificates shall be
issued in the name of the Holder or in such name or names as may be directed by
the Holder; provided, however, that in the
event certificates for Warrant Shares are to be issued in a name other than the
name of the Holder, this Warrant when surrendered for exercise shall be
accompanied by the Assignment Form attached hereto duly executed by the Holder
and the Company may require, as a condition thereto, the payment of a sum
sufficient to reimburse it for any transfer tax incidental thereto.

     

    vii.         Closing of
Books.  The Company will not close its stockholder books or
records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

     

    e)           Holder’s Exercise
Limitations.  The Company shall not effect any exercise of this
Warrant, and a Holder shall not have the right to exercise any portion of this
Warrant, pursuant to Section 2 or otherwise, to the extent that after giving
effect to such issuance after exercise as set forth on the applicable Notice of
Exercise, the Holder (together with the Holder’s Affiliates, and any other
Persons acting as a group together with the Holder or any of the Holder’s
Affiliates), would beneficially own in excess of the Beneficial Ownership
Limitation (as defined below).  For purposes of the foregoing sentence, the
number of shares of Common Stock beneficially owned by the Holder and its
Affiliates shall include the number of shares of Common Stock issuable upon
exercise of this Warrant with respect to which such determination is being made,
but shall exclude the number of shares of Common Stock which would be issuable
upon (i) exercise of the remaining, nonexercised portion of this Warrant
beneficially owned by the Holder or any of its Affiliates and (ii) exercise or
conversion of the unexercised or nonconverted portion of any other securities of
the Company (including, without limitation, any other  Common Stock
Equivalents) subject to a limitation on conversion or exercise analogous to the
limitation contained herein beneficially owned by the Holder or any of its
Affiliates.  Except as set forth in the preceding sentence, for purposes of
this Section 2(e), beneficial ownership shall be calculated in accordance with
Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder, it being acknowledged by the Holder that the Company is not
representing to the Holder that such calculation is in compliance with Section
13(d) of the Exchange Act and the Holder is solely responsible for any schedules
required to be filed in accordance therewith.   To the extent
that the limitation contained in this Section 2(e) applies, the determination of
whether this Warrant is exercisable (in relation to other securities owned by
the Holder together with any Affiliates) and of which

     

    
      
         

      

      
        5

        
          

        

      

      
         

      

    

    portion
of this Warrant is exercisable shall be in the sole discretion of the Holder,
and the submission of a Notice of Exercise shall be deemed to be the Holder’s
determination of whether this Warrant is exercisable (in relation to other
securities owned by the Holder together with any Affiliates) and of which
portion of this Warrant is exercisable, in each case subject to the Beneficial
Ownership Limitation, and the Company shall have no obligation to verify or
confirm the accuracy of such determination.   In addition, a
determination as to any group status as contemplated above shall be determined
in accordance with Section 13(d) of the Exchange Act and the rules and
regulations promulgated thereunder.  For purposes of this Section
2(e), in determining the number of outstanding shares of Common Stock, a Holder
may rely on the number of outstanding shares of Common Stock as reflected in (A)
the Company’s most recent periodic or annual report filed with the Commission,
as the case may be, (B) a more recent public announcement by the Company or (C)
a more recent written notice by the Company or the Transfer Agent setting forth
the number of shares of Common Stock outstanding.  Upon the written or oral
request of a Holder, the Company shall within two Trading Days confirm orally
and in writing to the Holder the number of shares of Common Stock then
outstanding.  In any case, the number of outstanding shares of Common Stock
shall be determined after giving effect to the conversion or exercise of
securities of the Company, including this Warrant, by the Holder or its
Affiliates since the date as of which such number of outstanding shares of
Common Stock was reported.  The “Beneficial Ownership
Limitation” shall be 9.99% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of shares of Common
Stock issuable upon exercise of this Warrant.  The Holder, upon not
less than 61 days’ prior notice to the Company, may increase or decrease the
Beneficial Ownership Limitation provisions of this Section 2(e), provided that
the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of
shares of the Common Stock outstanding immediately after giving effect to the
issuance of shares of Common Stock upon exercise of this Warrant held by the
Holder and the provisions of this Section 2(e) shall continue to
apply.  Any such increase or decrease will not be effective until the
61st day
after such notice is delivered to the Company.  The provisions of this
paragraph shall be construed and implemented in a manner otherwise than in
strict conformity with the terms of this Section 2(e) to correct this paragraph
(or any portion hereof) which may be defective or inconsistent with the intended
Beneficial Ownership Limitation herein contained or to make changes or
supplements necessary or desirable to properly give effect to such limitation.
The limitations contained in this paragraph shall apply to a successor holder of
this Warrant.

     

    Section
3.           Certain
Adjustments.

     

    a)           Stock Dividends and
Splits. If the Company, at any time while this Warrant is outstanding,
except for dividends payable pursuant to the Preferred Shares: (i) pays a stock
dividend or otherwise makes a distribution or distributions on shares of its
Common Stock or any other equity or equity equivalent securities payable in
shares of Common Stock (which, for avoidance of doubt, shall not include any
shares of Common

     

    
      
         

      

      
        6

        
          

        

      

      
         

      

    

    Stock
issued by the Company upon exercise of this Warrant), (ii) subdivides
outstanding shares of Common Stock into a larger number of shares, (iii)
combines (including by way of reverse stock split) outstanding shares of Common
Stock into a smaller number of shares or (iv) issues by reclassification of
shares of the Common Stock any shares of capital stock of the Company, then in
each case the Exercise Price shall be multiplied by a fraction of which the
numerator shall be the number of shares of Common Stock (excluding treasury
shares, if any) outstanding immediately before such event and of which the
denominator shall be the number of shares of Common Stock outstanding
immediately after such event, and the number of shares issuable upon exercise of
this Warrant shall be proportionately adjusted such that the aggregate Exercise
Price of this Warrant shall remain unchanged.  Any adjustment made
pursuant to this Section 3(a) shall become effective immediately after the
record date for the determination of stockholders entitled to receive such
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision, combination or
re-classification.

     

    b)           RESERVED.

     

    c)           Subsequent Rights
Offerings.  If the Company, at any time while the Warrant is
outstanding, shall issue rights, options or warrants to all holders of Common
Stock (and not to the Holders) entitling them to subscribe for or purchase
shares of Common Stock at a price per share less than the VWAP on the record
date mentioned below, then, the Exercise Price shall be multiplied by a
fraction, of which the denominator shall be the number of shares of the Common
Stock outstanding on the date of issuance of such rights, options or warrants
plus the number of additional shares of Common Stock offered for subscription or
purchase, and of which the numerator shall be the number of shares of the Common
Stock outstanding on the date of issuance of such rights, options or warrants
plus the number of shares which the aggregate offering price of the total number
of shares so offered (assuming receipt by the Company in full of all
consideration payable upon exercise of such rights, options or warrants) would
purchase at such VWAP.  Such adjustment shall be made whenever such
rights, options or warrants are issued, and shall become effective immediately
after the record date for the determination of stockholders entitled to receive
such rights, options or warrants.

     

    d)           Pro Rata
Distributions.  If the Company, at any time while this Warrant
is outstanding, shall distribute to all holders of Common Stock (and not to the
Holders) evidences of its indebtedness or assets (including cash and cash
dividends) or rights or warrants to subscribe for or purchase any security other
than the Common Stock), then in each such case the Exercise Price shall be
adjusted by multiplying the Exercise Price in effect immediately prior to the
record date fixed for determination of stockholders entitled to receive such
distribution by a fraction of which the denominator shall be the VWAP determined
as of the record date mentioned above, and of which the numerator shall be such
VWAP on such record date less the then per share fair market value at such
record date of the portion of such assets or evidence of indebtedness or rights
or warrants so distributed applicable to one outstanding share of the Common
Stock as determined by the Board of Directors in good faith.  In
either case the adjustments shall be described in a statement provided to the
Holder of the portion of assets or evidences of indebtedness 

     

    
      
         

      

      
        7

        
          

        

      

      
         

      

    

    so
distributed or such subscription rights applicable to one share of Common
Stock.  Such adjustment shall be made whenever any such distribution
is made and shall become effective immediately after the record date mentioned
above.

     

    e)           Fundamental
Transaction. If, at any time while this Warrant is outstanding, (i) the
Company, directly or indirectly, in one or more related transactions effects any
merger or consolidation of the Company with or into another Person, (ii) the
Company, directly or indirectly, effects any sale, lease, license, assignment,
transfer, conveyance or other disposition of all or substantially all of its
assets in one or a series of related transactions, (iii) any, direct or
indirect, purchase offer, tender offer or exchange offer (whether by the Company
or another Person) is completed pursuant to which holders of Common Stock are
permitted to sell, tender or exchange their shares for other securities, cash or
property and has been accepted by the holders of 50% or more of the outstanding
Common Stock, (iv) the Company, directly or indirectly, in one or more related
transactions effects any reclassification, reorganization or recapitalization of
the Common Stock or any compulsory share exchange pursuant to which the Common
Stock is effectively converted into or exchanged for other securities, cash or
property, (v) the Company, directly or indirectly, in one or more related
transactions consummates a stock or share purchase agreement or other business
combination (including, without limitation, a reorganization, recapitalization,
spin-off or scheme of arrangement) with another Person whereby such other Person
acquires more than 50% of the outstanding shares of Common Stock (not including
any shares of Common Stock held by the other Person or other Persons making or
party to, or associated or affiliated with the other Persons making or party to,
such stock or share purchase agreement or other business combination) (each a
“Fundamental
Transaction”), then, upon any subsequent exercise of this Warrant, the
Holder shall have the right to receive, for each Warrant Share that would have
been issuable upon such exercise immediately prior to the occurrence of such
Fundamental Transaction, at the option of the Holder (without regard to any
limitation in Section 2(e) on the exercise of this Warrant), the number of
shares of Common Stock of the successor or acquiring corporation or of the
Company, if it is the surviving corporation, and any additional consideration
(the “Alternate
Consideration”) receivable as a result of such Fundamental Transaction by
a holder of the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to such Fundamental Transaction (without regard to
any limitation in Section 2(e) on the exercise of this Warrant).  For
purposes of any such exercise, the determination of the Exercise Price shall be
appropriately adjusted to apply to such Alternate Consideration based on the
amount of Alternate Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the
Exercise Price among the Alternate Consideration in a reasonable manner
reflecting the relative value of any different components of the Alternate
Consideration.  If holders of Common Stock are given any choice as to
the securities, cash or property to be received in a Fundamental Transaction,
then the Holder shall be given the same choice as to the Alternate Consideration
it receives upon any exercise of this Warrant following such Fundamental
Transaction.  Notwithstanding anything to the contrary, in the event
of a Fundamental Transaction that is (1) an all cash transaction, (2) a “Rule
13e-3 transaction” as defined in Rule 13e-3 under the Exchange Act, or (3) a
Fundamental Transaction involving a person or entity not traded on a national
securities exchange, the Company or any Successor

    Entity
(as defined below) shall, at the Holder’s option, exercisable at any time
concurrently with, or within 30 days after, the consummation of the Fundamental
Transaction, purchase this Warrant from the Holder by paying to the Holder an
amount of cash equal to the Black Scholes Value of the remaining unexercised
portion of this Warrant on the date of the consummation of such Fundamental
Transaction, provided that the foregoing right shall not be exercisable by the
Holder with respect to a Fundamental Transaction (I) under clause (ii) above in
this paragraph that results solely from the Company selling all or substantially
all of the assets of Buckeye Industrial Mining Co. to an unaffiliated and
unrelated Person so long as the Company together with its Subsidiaries continues
to have bona fide, substantial and continuing business operations and activities
at all times after such sale is consummated (it being understood and agreed that
(1) the foregoing right shall become immediately exercisable by the Holder with
respect to such Fundamental Transaction for a period of 30 days commencing on
the date that the Company together with its Subsidiaries ceases to have bona
fide, substantial and continuing business operations and activities at any time
after such sale is consummated, (2) the Company shall provide the Holder with
prompt written notice of such cessation and (3) Black Scholes Value with respect
to such Fundamental Transaction shall always be determined as of the day of
consummation of such Fundamental Transaction but (A) the remaining option time
shall be equal to (W) the time between the date of the public announcement of
such Fundamental Transaction and the Termination Date if such cessation occurs
on or prior to the one (1) year anniversary of the consummation of such
Fundamental Transaction or (X) the time between the date of such cessation and
the Termination Date if such cessation occurs after the one (1) year anniversary
of the consummation of such Fundamental Transaction (as applicable) and (B) the
risk-free interest rate shall be equal to (Y) a risk-free interest rate
corresponding to the U.S. Treasury rate for a period equal to the time between
the date of the public announcement of such Fundamental Transaction and the
Termination Date if such cessation occurs on or prior to the one (1) year
anniversary of the consummation of such Fundamental Transaction or (Z) a
risk-free interest rate corresponding to the U.S. Treasury rate for a period
equal to the time between the date of such cessation and the Termination Date if
such cessation occurs after the one (1) year anniversary of the consummation of
such Fundamental Transaction (as applicable)) or (II) resulting solely from the
Company’s contemplated offering pursuant to a universal shelf registration
statement for $50,000,000.   “Black Scholes Value”
means the value of this Warrant based on the Black and Scholes Option Pricing
Model obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”)
determined as of the day of consummation of the applicable Fundamental
Transaction for pricing purposes and reflecting (A) a risk-free interest rate
corresponding to the U.S. Treasury rate for a period equal to the time between
the date of the public announcement of the applicable Fundamental Transaction
and the Termination Date, (B) an expected volatility equal to the greater of
100% and the 100 day volatility obtained from the HVT function on Bloomberg as
of the Trading Day immediately following the public announcement of the
applicable Fundamental Transaction, (C) if applicable, the underlying price per
share used in such calculation shall be the sum of the price per share being
offered in cash, if any, plus the value of any non-cash consideration, if any,
being offered in such Fundamental Transaction and (D) a remaining option time
equal to the time between the date of the public announcement of 

     

    
      
         

      

      
        9

        
          

        

      

      
         

      

    

    the
applicable Fundamental Transaction and the Termination Date.  The
Company shall cause any successor entity in a Fundamental Transaction in which
the Company is not the survivor (the “Successor Entity”) to
assume in writing all of the obligations of the Company under this Warrant and
the other Transaction Documents in accordance with the provisions of this
Section 3(e) pursuant to written agreements in form and substance reasonably
satisfactory to the Holder and approved by the Holder (without unreasonable
delay) prior to such Fundamental Transaction and shall, at the option of the
holder of this Warrant, deliver to the Holder in exchange for this Warrant a
security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Warrant which is exercisable for a
corresponding number of shares of capital stock of such Successor Entity (or its
parent entity) equivalent to the shares of Common Stock acquirable and
receivable upon exercise of this Warrant (without regard to any limitations on
the exercise of this Warrant) prior to such Fundamental Transaction, and with an
exercise price which applies the exercise price hereunder to such shares of
capital stock (but taking into account the relative value of the shares of
Common Stock pursuant to such Fundamental Transaction and the value of such
shares of capital stock, such number of shares of capital stock and such
exercise price being for the purpose of protecting the economic value of this
Warrant immediately prior to the consummation of such Fundamental Transaction),
and which is reasonably satisfactory in form and substance to the Holder. Upon
the occurrence of any such Fundamental Transaction, the Successor Entity shall
succeed to, and be substituted for (so that from and after the date of such
Fundamental Transaction, the provisions of this Warrant and the other
Transaction Documents referring to the “Company” shall refer instead to the
Successor Entity), and may exercise every right and power of the Company and
shall assume all of the obligations of the Company under this Warrant and the
other Transaction Documents with the same effect as if such Successor Entity had
been named as the Company herein.  The provisions of this paragraph
shall apply similarly and equally to successive Fundamental Transactions and
shall be applied as if this Warrant (and any such subsequent warrants) were
fully exercisable and without regard to any limitations on the exercise of this
Warrant (provided that the Holder shall continue to be entitled to the benefit
of the Beneficial Ownership Limitation, applied however with respect to shares
of capital stock registered under the Exchange Act and thereafter receivable
upon exercise of this Warrant (or any such other warrant)).

     

    f)           Voluntary Adjustment by the
Company.  The Company may, at any time during the term of this
Warrant, reduce the then current exercise price to any amount and for any period
of time deemed appropriate by the Board of Directors

     

    g)           Calculations. All
calculations under this Section 3 shall be made to the nearest cent or the
nearest 1/100th of a share, as the case may be. For purposes of this Section 3,
the number of shares of Common Stock deemed to be issued and outstanding as of a
given date shall be the sum of the number of shares of Common Stock (excluding
treasury shares, if any) issued and outstanding.

     

    h)           Notice to
Holder.

    i.           Adjustment to Exercise
Price. Whenever the Exercise Price is adjusted pursuant to any provision
of this Section 3, the Company shall promptly mail to the Holder a notice
setting forth the Exercise Price after such adjustment and setting forth a brief
statement of the facts requiring such adjustment. If the Company enters into a
Variable Rate Transaction, despite the prohibition thereon in the Purchase
Agreement, the Company shall be deemed to have issued Common Stock or Common
Stock Equivalents at the lowest possible conversion or exercise price at which
such securities may be converted or exercised.

     

    ii.      Notice to Allow Exercise by
Holder. If (A) the Company shall declare a dividend (or any other
distribution in whatever form) on the Common Stock, (B) the Company shall
declare a special nonrecurring cash dividend on or a redemption of the Common
Stock, (C) the Company shall authorize the granting to all holders of the Common
Stock rights or warrants to subscribe for or purchase any shares of capital
stock of any class or of any rights, (D) the approval of any stockholders of the
Company shall be required in connection with any reclassification of the Common
Stock, any consolidation or merger to which the Company is a party, any sale or
transfer of all or substantially all of the assets of the Company, or any
compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property, or (E) the Company shall authorize the voluntary
or involuntary dissolution, liquidation or winding up of the affairs of the
Company, then, in each case, the Company shall cause to be mailed to the Holder
at its last address as it shall appear upon the Warrant Register of the Company,
at least 20 calendar days prior to the applicable record or effective date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution, redemption, rights or
warrants, or if a record is not to be taken, the date as of which the holders of
the Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which
such reclassification, consolidation, merger, sale, transfer or share exchange
is expected to become effective or close, and the date as of which it is
expected that holders of the Common Stock of record shall be entitled to
exchange their shares of the Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer or
share exchange; provided that the failure to mail such notice or any defect
therein or in the mailing thereof shall not affect the validity of the corporate
action required to be specified in such notice.  To the extent that
any notice provided hereunder constitutes, or contains, material, non-public
information regarding the Company or any of the Subsidiaries, the Company shall
simultaneously file such notice with the Commission pursuant to a Current Report
on Form 8-K.  The Holder shall remain entitled to exercise this
Warrant during the period commencing on the date of such notice to the effective
date of the event triggering such notice  except as may otherwise be
expressly set forth herein.

    Section
4.           Transfer of
Warrant.

     

    a)           Transferability.  Subject
to compliance with any applicable securities laws and the conditions set forth
in Section 4(d) hereof and to the provisions of Section 4.1 of the Purchase
Agreement, this Warrant and all rights hereunder (including, without limitation,
any registration rights) are transferable, in whole or in part, upon surrender
of this Warrant at the principal office of the Company or its designated agent,
together with a written assignment of this Warrant substantially in the form
attached hereto duly executed by the Holder or its agent or attorney and funds
sufficient to pay any transfer taxes payable upon the making of such
transfer.  Upon such surrender and, if required, such payment, the
Company shall execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees, as applicable, and in the denomination or denominations
specified in such instrument of assignment, and shall issue to the assignor a
new Warrant evidencing the portion of this Warrant not so assigned, and this
Warrant shall promptly be cancelled.  The Warrant, if properly
assigned in accordance herewith, may be exercised by a new holder for the
purchase of Warrant Shares without having a new Warrant issued.

     

    b)           New Warrants. This
Warrant may be divided or combined with other Warrants upon presentation hereof
at the aforesaid office of the Company, together with a written notice
specifying the names and denominations in which new Warrants are to be issued,
signed by the Holder or its agent or attorney.  Subject to compliance
with Section 4(a), as to any transfer which may be involved in such division or
combination, the Company shall execute and deliver a new Warrant or Warrants in
exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice. All Warrants issued on transfers or exchanges shall be dated
the Initial Exercise Date and shall be identical with this Warrant except as to
the number of Warrant Shares issuable pursuant thereto.

     

    c)           Warrant Register. The
Company shall register this Warrant, upon records to be maintained by the
Company for that purpose (the “Warrant Register”),
in the name of the record Holder hereof from time to time.  The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, absent actual notice to the
contrary.

     

    d)           Transfer
Restrictions. If, at the time of the surrender of this Warrant in
connection with any transfer of this Warrant, the transfer of this Warrant shall
not be either (i) registered pursuant to an effective registration statement
under the Securities Act and under applicable state securities or blue sky laws
or (ii) eligible for resale without volume or manner-of-sale restrictions or
current public information requirements pursuant to Rule 144, the Company may
require, as a condition of allowing such transfer, that the Holder or transferee
of this Warrant, as the case may be, comply with the provisions of Section 5.7
of the Purchase Agreement.

     

    e)           Representation by the
Holder.  The Holder, by the acceptance hereof, represents and
warrants that it is acquiring this Warrant and, upon any exercise
hereof,

     

    
      
         

      

      
        12

        
          

        

      

      
         

      

    

    will
acquire the Warrant Shares issuable upon such exercise, for its own account and
not with a view to or for distributing or reselling such Warrant Shares or any
part thereof in violation of the Securities Act or any applicable state
securities law, except pursuant to sales registered or exempted under the
Securities Act.

     

    Section
5.           Miscellaneous.

     

    a)           No Rights as Stockholder
Until Exercise.  This Warrant does not entitle the Holder to
any voting rights, dividends or other rights as a stockholder of the Company
prior to the exercise hereof as set forth in Section 2(d)(i).

     

    b)           Loss, Theft, Destruction or
Mutilation of Warrant. The Company covenants that upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant or any stock certificate relating to
the Warrant Shares, and in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it (which, in the case of the Warrant, shall
not include the posting of any bond), and upon surrender and cancellation of
such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

     

    c)           Saturdays, Sundays,
Holidays, etc.  If the last or appointed day for the taking of
any action or the expiration of any right required or granted herein shall not
be a Business Day, then, such action may be taken or such right may be exercised
on the next succeeding Business Day.

     

    d)           Authorized
Shares.

     

    The
Company covenants that, during the period the Warrant is outstanding, it will
reserve from its authorized and unissued Common Stock a sufficient number of
shares to provide for the issuance of the Warrant Shares upon the exercise of
any purchase rights under this Warrant.  The Company further covenants
that its issuance of this Warrant shall constitute full authority to its
officers who are charged with the duty of executing stock certificates to
execute and issue the necessary certificates for the Warrant Shares upon the
exercise of the purchase rights under this Warrant.  The Company will
take all such reasonable action as may be necessary to assure that such Warrant
Shares may be issued as provided herein without violation of any applicable law
or regulation, or of any requirements of the Trading Market upon which the
Common Stock may be listed.  The Company covenants that all Warrant
Shares which may be issued upon the exercise of the purchase rights represented
by this Warrant will, upon exercise of the purchase rights represented by this
Warrant and payment for such Warrant Shares in accordance herewith, be duly
authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges created by the Company in respect of the issue thereof
(other than taxes in respect of any transfer occurring contemporaneously with
such issue).

     

    
      
         

      

      
        13

        
          

        

      

      
         

      

    

    Except
and to the extent as waived or consented to by the Holder, the Company shall not
by any action, including, without limitation, amending its certificate of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such actions as may be necessary or
appropriate to protect the rights of Holder as set forth in this Warrant against
impairment.  Without limiting the generality of the foregoing, the
Company will (i) not increase the par value of any Warrant Shares above the
amount payable therefor upon such exercise immediately prior to such increase in
par value, (ii) take all such action as may be necessary or appropriate in order
that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares upon the exercise of this Warrant and (iii) use commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof, as may be,
necessary to enable the Company to perform its obligations under this
Warrant.

     

    Before
taking any action which would result in an adjustment in the number of Warrant
Shares for which this Warrant is exercisable or in the Exercise Price, the
Company shall obtain all such authorizations or exemptions thereof, or consents
thereto, as may be necessary from any public regulatory body or bodies having
jurisdiction thereof.

     

    e)           Jurisdiction. All
questions concerning the construction, validity, enforcement and interpretation
of this Warrant shall be determined in accordance with the provisions of the
Purchase Agreement.

     

    f)           Restrictions.  The
Holder acknowledges that the Warrant Shares acquired upon the exercise of this
Warrant, if not registered and the Holder does not utilize cashless exercise,
will have restrictions upon resale imposed by state and federal securities
laws.

     

    g)           Nonwaiver and
Expenses.  No course of dealing or any delay or failure to
exercise any right hereunder on the part of Holder shall operate as a waiver of
such right or otherwise prejudice Holder’s rights, powers or remedies. Without
limiting any other provision of this Warrant or the Purchase Agreement, if the
Company willfully and knowingly fails to comply with any provision of this
Warrant, which results in any material damages to the Holder, the Company shall
pay to Holder such amounts as shall be sufficient to cover any costs and
expenses including, but not limited to, reasonable attorneys’ fees, including
those of appellate proceedings, incurred by Holder in collecting any amounts due
pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.

     

    h)           Notices.  Any
notice, request or other document required or permitted to be given or delivered
to the Holder by the Company shall be delivered in accordance with the notice
provisions of the Purchase Agreement.

     

    
      
         

      

      
        14

        
          

        

      

      
         

      

    

    i)           Limitation of
Liability.  No provision hereof, in the absence of any
affirmative action by Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of Holder, shall
give rise to any liability of Holder for the purchase price of any Common Stock
or as a stockholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

     

    j)           Remedies.  The
Holder, in addition to being entitled to exercise all rights granted by law,
including recovery of damages, will be entitled to specific performance of its
rights under this Warrant.  The Company agrees that monetary damages
would not be adequate compensation for any loss incurred by reason of a breach
by it of the provisions of this Warrant and hereby agrees to waive and not to
assert the defense in any action for specific performance that a remedy at law
would be adequate.

     

    k)           Successors and
Assigns.  Subject to applicable securities laws, this Warrant
and the rights and obligations evidenced hereby shall inure to the benefit of
and be binding upon the successors and permitted assigns of the Company and the
successors and permitted assigns of Holder.  The provisions of this
Warrant are intended to be for the benefit of any Holder from time to time of
this Warrant and shall be enforceable by the Holder or holder of Warrant
Shares.

     

    l)           Amendment.  This
Warrant may be modified or amended or the provisions hereof waived with the
written consent of the Company and the Holder.

     

    m)           Severability.  Wherever
possible, each provision of this Warrant shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this
Warrant shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provisions or the remaining provisions of
this Warrant.

     

    n)           Headings.  The
headings used in this Warrant are for the convenience of reference only and
shall not, for any purpose, be deemed a part of this Warrant.

                    This
Amended and Restated CREDIT AGREEMENT, dated as of April 20, 2005, is entered
into by and among QUIXOTE CORPORATION, a Delaware corporation, as Borrower (the
“Borrower”), and LASALLE BANK NATIONAL ASSOCIATION, a national banking association,
as Lender (the “Lender”). The parties hereto agree as follows:

RECITALS:

                    A.     The
Borrower, the Lender and certain other banks, (“Existing Lenders”) entered into
that certain Credit Agreement, dated as of May 16, 2003, as amended by a First
Amendment, dated as of December 9, 2003; by a Second Amendment, dated as of
June 30, 2004; by a Third Amendment, dated as of September 10, 2004; and by a
Fourth Amendment dated as of February 9, 2005 (“Existing Credit Agreement”),
pursuant to which Existing Credit Agreement the Existing Lenders have made, (i)
Revolving Loans to the Borrower evidenced by certain Revolving Notes, dated as
of September 10, 2004, in the maximum aggregate principal amount of Thirty
Eight Million Dollars and 00/100 ($38,000,000), executed by the Borrower and
made payable pro rata to the order of the Existing Lenders (the “Revolving
Notes”) and (ii) Term Loans to the Borrower evidenced by certain Term Notes,
dated as of May 16, 2003, in the aggregate original principal amount of Twenty
Million Dollars and 00/100 ($20,000,000), executed by the Borrower and made
payable pro rata to the order of the Existing Lenders (the “Term Notes”).

                    B.     The
Borrower, as of February 9, 2005, issued $40,000,000 in aggregate principal
amount of 7% Convertible Senior Subordinated Notes, due February 15, 2025 (the
“New Subordinated Notes”), the proceeds of which New Subordinated Notes (i)
repaid in full Borrower’s obligations on the Term Loans and Notes and terminated
the Existing Lender Term Loan Commitment as defined in the Existing Credit
Agreement and (ii) repaid a portion of the outstanding Revolving Loans. 

                    C.     The
Lender and Borrower have agreed to amend and restate the terms of the Existing
Credit Agreement, and the Borrower has requested and the Lender has agreed that
Lender, individually on its own, continue the Revolving Loan Commitment under
the Existing Credit Agreement consisting of a Revolving Credit Commitment in
the amount of $30,000,000 (with a sublimit for the issuance of Letters of
Credit in the amount of $10,000,000).

                    D.     The
Existing Lenders (other than Lender) have agreed to sell to Lender their
outstanding pro rata share of the Revolving Loans and to assign their rights
and obligations to the Lender. 

                    E.     Nothing
in this Agreement or in any of the other Loan Documents shall be deemed to
constitute a novation or to have extinguished or discharged the indebtedness
and obligations under the Existing Credit Agreement and the documents executed
and delivered in connection therewith all of which, except as provided herein,
continue under and shall be governed by this Agreement and the other Loan
Documents.

all present and future rights of the Borrower or such Subsidiary to payment for

performance, and all rights in any merchandise or goods which any of the same
may represent, and all rights, title, security and guarantees with respect to
each of the foregoing, including, without limitation, any right of stoppage in
transit.

                    “Acquisition”

the assets of any firm, corporation or division thereof, whether through
purchase of assets, merger or otherwise or (ii) directly or indirectly acquires

                     (i)     If
 at any time and for any reason the Revolving Credit Obligations are greater
 than the Revolving Loan Availability the Borrower shall immediately make a
 mandatory prepayment of the respective Obligations in an amount equal to such
 excess.

 
	
  

 	
  

 
	
  

 	
                     (ii)     In
 addition to any other mandatory repayments pursuant to this Section 2.3, on
 each date after the date of this Agreement on which borrower or any
 Subsidiary receives proceeds from the following transactions, Borrower shall
 make the following mandatory prepayments, except as otherwise provided below
 to repay the outstanding principal amount of Revolving Loans (with no

                     (w)     an
 amount equal to 80% of the Net Sale Proceeds of any Asset Sale shall be
 applied to repayment of the outstanding principal amount of the Revolving
 Loans subject to an allowance for like-kind exchanges in an aggregate amount
 not to exceed $1,000,000 in any fiscal year;

 
	
  

 	
  

 
	
  

 	
                     (x)     an
 amount equal to 100% of Net Recovery Event Proceeds received from any
 Recovery Event, provided that so long as no Event of Default then exists,
 such Net Recovery Event Proceeds shall not be required to be so applied on
 such date to the extent that Borrower has delivered a certificate to the
 Lender on or prior to such date stating that such proceeds shall be used (or
 contractually committed to be used) within 180 days following the date of
 receipt of such Net Recovery Event Proceeds from such Recovery Event to
 replace or restore any properties or assets in respect of which such Net
 Recovery Event Proceeds were paid (which certificate shall set forth the
 estimates of the proceeds to be so expended), and provided further, that if
 all or any portion of such Net Recovery Event Proceeds are not so used (or
 contractually committed to be used) within such 180-day period, such remaining
 portion shall be applied as a mandatory repayment as provided above (without
 giving effect to the immediately preceding proviso); 

 
	
  

 	
  

 
	
  

 	
                     (y)     an
 amount equal to 60% of the net proceeds received from any issuance of capital
 stock or any equity interests by Borrower; and

 
	
  

 	
  

 
	
  

 	
                     (z)     an
 amount equal to 100% of the net proceeds received from the incurrence of
 Indebtedness (other than Indebtedness permitted to be incurred pursuant to
 Section 7.3(A) of this Agreement.

 

                    2.4     Reduction
of Commitments. The Borrower may permanently reduce the Revolving Loan
Commitment in whole, or in part an aggregate minimum amount of $5,000,000 with
respect thereto and integral multiples of $1,000,000 in excess of that amount
with respect thereto (unless the Revolving Loan Commitment is reduced in
whole), upon at least three (3) Business Day’s prior written notice to the
Lender, which notice shall specify the amount of any such reduction; provided,
however, that the amount of the Revolving Loan Commitment may not be
reduced below the aggregate principal Dollar Amount of the outstanding
Revolving Credit Obligations. All accrued facility fees shall be payable on the
effective date of any termination of the obligations of the Lender to make
Loans hereunder.

                    2.5     Method
of Borrowing. Not later than 3:00 p.m. (Chicago time) on each Borrowing
Date, Lender shall make available its Revolving Loan in immediately available
funds in Dollars to the Borrower at the Lender’s address or its Eurodollar
Payment Office.

                    2.6     Method of Selecting Types and
Interest Periods for Advances. The Borrower shall select the Type of
Advance and, in the case of each Eurodollar Rate Advance, the Interest Period
applicable to each Advance from time to time. The Borrower shall give the
Lender irrevocable notice in substantially the form of Exhibit A
hereto (a “Borrowing Election Notice”) not later than 12:00 noon
(Chicago time) (a) on the Borrowing Date of each Floating Rate Advance,
and (b) three (3) Business Days before the Borrowing Date for each
Eurodollar

Rate Advance specifying: (i) the Borrowing Date (which shall be a
Business Day) of such Advance; (ii) the aggregate amount of such Advance;
(iii) the Type of Advance selected; and (iv) in the case of each
Eurodollar Rate Advance, the Interest Period applicable thereto. Each Floating
Rate Advance and all Obligations other than Loans shall bear interest from and
including the date of the making of such Advance, in the case of Loans, and the
date such Obligation is due and owing in the case of such other Obligations, to
(but not including) the date of repayment thereof at the Floating Rate changing
when and as such Floating Rate changes. Changes in the rate of interest on that
portion of any Advance maintained as a Floating Rate Loan will take effect
simultaneously with each change in the Alternate Base Rate. Each Eurodollar
Rate Advance shall bear interest from and including the first day of the
Interest Period applicable thereto to (but not including) the last day of such
Interest Period at the interest rate determined as applicable to such
Eurodollar Rate Advance. 

                    2.7     Minimum
Amount of Each Advance. Each Advance (other than an Advance to repay a
Reimbursement Obligation) shall be in the minimum amount of $250,000 and in
multiples of $100,000 if in excess thereof; provided, however,
that any Floating Rate Advance may be in the amount of the unused Revolving
Loan Availability.

                    2.8     Method
of Selecting Types, and Interest Periods for Conversion and Continuation of
Advances.

                    (A)     Right
to Convert. The Borrower may elect from time to time. subject to the
provisions of Section 2.3 and this Section 2.9, to
convert all or any part of a Loan of any Type into any other Type or Types of
Loan; provided that any conversion of any Eurodollar Rate Advance shall be made
on, and only on, the last day of the Interest Period applicable thereto.

                    (B)     Automatic
Conversion and Continuation. Floating Rate Loans shall continue as Floating
Rate Loans unless and until such Floating Rate Loans are converted into
Eurodollar Rate Loans. Eurodollar Rate Loans shall continue as Eurodollar Rate
Loans until the end of the then applicable Interest Period therefor, at which
time such Eurodollar Rate Loans shall be automatically converted into Floating
Rate Loans unless the Borrower shall have given the Lender notice in accordance
with Section 2.9(D) requesting that, at the end of such Interest
Period, such Eurodollar Rate Loans continue as a Eurodollar Rate Loan. 

                    (C)     No
Conversion Post-Default; Limited Conversion Post-Unmatured Default.
Notwithstanding anything to the contrary contained in Section 2.9(A)
or Section 2.9(B), (x) no Loan may be converted into or
continued as a Eurodollar Rate Loan (except with the consent of the Lender)
when any Default has occurred and is continuing and (y) no Loan may be
converted into or continued as a Eurodollar Rate Loan with an Interest Period
greater than one month (except with the consent of the Lender) when any
Unmatured Default has occurred and is continuing.

                    (D)     Borrowing/Election
Notice. The Borrower shall give the Lender an irrevocable
Borrowing/Election Notice of each conversion of a Floating Rate Loan into a
Eurodollar Rate Loan or continuation of a Eurodollar Rate Loan not later than
12:00 noon (Chicago time) three (3) Business Days prior to the date
of the requested conversion or

continuation, with respect to any Loan to be converted or continued as
a Eurodollar Rate Loan specifying: (i) the requested date (which shall be
a Business Day) of such conversion or continuation; (ii) the amount and
Type of the Loan to be converted or continued; and (iii) the amount of
Eurodollar Rate Loan(s) into which such Loan is to be converted or continued,
and the duration of the Interest Period applicable thereto.

                    2.9     Default
Rate. After the occurrence and during the continuance of a Default, at the
option of the Lender, the interest rate(s) applicable to the Obligations shall
be equal to the Floating Rate hereunder plus two percent (2.0%) per
annum, and the Letter of Credit fee described in Section 3.8(A)
shall be equal to the then Applicable LC Fee Percentage plus two
percent (2.0%) per annum.

                    2.10     Method
of Payment. (a) All payments of principal, interest, fees, commissions and
L/C Obligations hereunder shall be made, without setoff, deduction or
counterclaim (unless indicated otherwise in Section 2.14(E)), in
immediately available funds to the Lender (i) at the Lender’s address
specified pursuant to Article XIV with respect to Advances or other
Obligations at any other Lending Installation of the Lender specified in
writing by the Lender to the Borrower, by 12:00 p.m. (Chicago time) on the date
when due. Each Advance shall be repaid or prepaid in the Dollar Amount borrowed
and interest payable thereon shall also be paid in such currency. Any payment
owing by the Borrower to Lender shall be deemed to have been paid to Lender by
the Borrower upon the Lender’s receipt of such payment from the Borrower. The
Borrower authorizes the Lender to charge the account of the Borrower maintained
with Lender for each payment of principal, interest, fees, commissions and L/C
Obligations as it becomes due hereunder. 

                    2.11     Evidence
of Debt.

                    (A)     Notes.
All Loans by Lender shall be evidenced by a single promissory note of the
Borrower. On the Closing Date, the Borrower shall deliver to the Lender a
Revolving Note, dated such date (together with all other promissory notes
accepted in substitution, renewal, or replacement therefor (including pursuant
to Section 2.13), a “Note” ), in the form of Exhibit G hereto,
with appropriate insertions and payable on its face to the order of such Lender
on the Revolving Loan Termination Date in the principal sum of the Revolving
Loan Commitment, subject, however, to the limitation that the principal amount
payable thereunder shall not at any time exceed the then unpaid principal
amount of all Loans made by such Lender. The Borrower hereby irrevocably
authorizes Lender to make or cause to be made, at or about the time of each
Revolving Loan made by it, an appropriate notation on the grid attached to the
Revolving Note payable to the order of Lender, reflecting the unpaid principal
amount of all Loans made by Lender. Lender agrees to make or cause to be made,
at or about the time of receipt of any payment of any principal of a Note
payable to its order, an appropriate notation on the grid attached to such
Revolving Note reflecting such payment. The aggregate unpaid amount of Loans
set forth on the grid attached to the Note shall be conclusive evidence (absent
manifest error) of the principal amount owing and unpaid on such Note. The
failure so to record any such Loan or payment, or any error in so recording any
such Loan or repayment, shall not, however, limit or otherwise affect the
obligations of the Borrower hereunder or under the Note to repay the principal
amount of the Loans together with all interest accruing thereon.

The Register maintained by the Lender pursuant to Section 13.3(D)
shall include a control account in which account shall be recorded (i) the
date and the amount of each Loan made hereunder, the Type thereof and the
Interest Period, if any, applicable thereto, (ii) the amount of any
principal or interest due and payable or to become due and payable from the
Borrower to Lender hereunder, (iii) the amount of any sum received by the
Lender hereunder and (iv) all other appropriate debits and credits as
provided in this Agreement, including, without limitation, all fees, charges,
expenses and interest.

                    (C)     Entries
in Register. The entries made in the Register maintained pursuant to
subsections (B) of this Section shall be conclusive and binding for all
purposes, absent manifest error, gross negligence or willful misconduct, unless
the Borrower objects to information contained in the Loan Accounts or the
Register within forty-five (45) days of the Borrower’s receipt of such
information; provided that the failure of Lender to maintain such accounts or
any error therein shall not in any manner affect the obligation of the Borrower
to repay the Loans in accordance with the terms of this Agreement.

                    2.12     Telephonic
Notices. The Borrower authorizes the Lender to extend Advances, effect
selections of Types of Advances and to transfer funds based on telephonic
notices made by any person or persons the Lender in good faith believes to be
acting on behalf of the Borrower. The Borrower agrees to deliver promptly to
the Lender a written confirmation, signed by an Authorized Officer (or such
other officer designated in writing to the Lender by an Authorized Officer so
long as such other officer is also permitted to make such delivery under the
Borrower’s organizational documents), if such confirmation is requested by the
Lender of each telephonic notice. If the written confirmation differs in any
material respect from the action taken by the Lender, the records of the Lender
shall govern absent manifest error, gross negligence or willful misconduct. In
case of disagreement concerning such notices, if the Lender has recorded
telephonic borrowing notices, such recordings will be made available to the
Borrower upon the Borrower’s request therefor.

                    2.13     Promise
to Pay; Interest and Facility Fees; Interest Payment Dates; Interest and Fee
Basis; Taxes.

                    (A)     Promise
to Pay. The Borrower unconditionally promises to pay when due the principal
amount of each Loan incurred by it and all other Obligations incurred by it,
and to pay all unpaid interest accrued thereon, in accordance with the terms of
this Agreement and the other Loan Documents.

                    (B)     Interest
Payment Dates. Interest accrued on each Floating Rate Loan shall be payable
on each Payment Date, commencing with the first such date to occur after the
date hereof, upon any prepayment whether by acceleration or otherwise, and at
the Revolving Loan Termination Date (whether by acceleration or otherwise).
Interest accrued on each Fixed-Rate Loan shall be payable on the last day of
its applicable Interest Period, on any date on which such Fixed-Rate Loan is
prepaid, whether by acceleration or otherwise, and at maturity. Interest
accrued on each Fixed-Rate Loan having an Interest Period longer than three
months shall also be payable on the last day of each three-month interval during
such Interest Period. Interest accrued on the principal balance of all other
Obligations shall be payable in arrears (i) on each

Payment Date, commencing on the first such Payment Date following the
incurrence of such Obligations, (ii) upon repayment thereof in full or in
part, and (iii) if not theretofore paid in full, at the time such other
Obligations become due and payable (whether by acceleration or otherwise).

                     (i)     The
 Borrower shall pay to the Lender from and after the date of this Agreement
 until the date on which the Revolving Loan Commitment shall be terminated in
 whole, a commitment fee accruing at the rate of the then Applicable
 Commitment Fee Percentage, on the amount of the unused Revolving Loan
 Commitment in effect on the date of such payment. All such commitment fees
 payable under this clause (C)(i) shall be payable quarterly in arrears
 on each Payment Date occurring after the date of this Agreement, and, in
 addition, on the date on which the Revolving Loan Commitment shall be
 terminated in whole.

 
	
  

 	
  

 	
  

 
	
  

 	
                     (ii)     The
 Borrower agrees to pay, on the Closing Date, to the Lender an upfront closing
 fee pursuant to the terms of the Lender’s Commitment Letter, dated March 16,
 2005.

                     (i)     Interest
 on all Eurodollar Rate Loans and on all fees shall be calculated for actual
 days elapsed on the basis of a 360-day year. Interest on all Floating Rate
 Loans shall be calculated for actual days elapsed on the basis of a 365-day
 year, or when appropriate 366-day year. Interest shall be payable for the day
 an Obligation is incurred but not for the day of any payment on the amount
 paid if payment is received prior to 2:00 p.m. (local time) at the place
 of payment. If any payment of principal of or interest on a Loan or any
 payment of any other Obligations shall become due on a day which is not a Business
 Day, such payment shall be made on the next succeeding Business Day and, in
 the case of a principal payment, such extension of time shall be included in
 computing interest, fees and commissions in connection with such payment.

 
	
  

 	
  

 
	
  

 	
                     (ii)     The
 Applicable Eurodollar Margin, Applicable ABR Margin, Applicable Commitment
 Fee Percentage and Applicable L/C Fee Percentage shall be determined on the
 basis of the then applicable Senior Leverage Ratio as described in this Section 2.13(D)(ii),
 from time to time by reference to the following table:

 Upon receipt of the financial statements delivered pursuant to Sections 7.1(A)(i)
 and (ii), as applicable, the Applicable Eurodollar Margin, the
 Applicable ABR Margin, the Applicable Commitment Fee Percentage and
 Applicable L/C Fee Percentage shall be adjusted, such adjustment being
 effective five (5) Business Days following the day such financial
 statements and compliance certificates are delivered pursuant to Section 7.1(A);
 provided, that if the Borrower shall not have timely delivered its
 financial statements and compliance certificates in accordance with the
 applicable provisions of Section 7.1(A), and such failure
 continues for five (5) days after notice from the Lender to the
 Borrower, then, at the discretion of the Lender, commencing on the date upon
 which such financial statements and compliance certificates should have been
 delivered and continuing until five (5) days after such financial
 statements and compliance certificates are actually delivered, it shall be
 assumed for purposes of determining the Applicable Eurodollar Margin, the
 Applicable ABR Margin, Applicable L/C Fee Percentage and Applicable
 Commitment Fee Percentage that the Senior Leverage Ratio was greater than 3.0
 to 1.0 and Level V pricing shall be applicable.

 
	
  

 	
  

 
	
  

 	
                     (iii)   Notwithstanding
 anything herein to the contrary, from the Closing Date through the
 fifth (5th) Business Day following the day financial statements are
 delivered pursuant to Section 7.1(A) for the fiscal year ending
 June 30, 2006, the Applicable Eurodollar Margin, the Applicable ABR Margin,
 the Applicable L/C Percentage and the Applicable Commitment Fee Percentage
 shall be determined based upon a Senior Leverage Ratio equal to Level IV

 and all payments by the Borrower hereunder (whether in respect of principal,
 interest, fees or otherwise) shall be made free and clear of and without
 deduction for any and all present or future taxes, levies, imposts,
 deductions, charges or withholdings or any interest, penalties or liabilities
 with respect thereto imposed by any Governmental Authority including those
 arising after the date hereof as a

 result of the adoption of or any change in any law, treaty, rule,
 regulation, guideline or determination of a Governmental Authority or any
 change in the interpretation or application thereof by a Governmental
 Authority but excluding, in the case of each Lender and the Lender, such
 taxes (including income taxes, franchise taxes and branch profit taxes) as
 are imposed on or measured by Lender’s net income or similar taxes imposed by
 the United States of America or any Governmental Authority of the
 jurisdiction under the laws of which Lender is organized or maintains a
 Lending Installation (all such non-excluded taxes, levies, imposts,
 deductions, charges, withholdings, and liabilities which the Lender or a
 Lender determines to be applicable to this Agreement, the other Loan
 Documents, the Revolving Loan Commitments, the Loans or the Letters of Credit
 being hereinafter referred to as “Taxes”). If the Borrower or the
 Lender shall be required by law to deduct or withhold any Taxes from or in
 respect of any sum payable hereunder or under the other Loan Documents to
 Lender (i) the sum payable shall be increased as may be necessary so
 that after making all required deductions or withholdings (including
 deductions or withholdings applicable to additional sums payable under this Section 2.14(E))
 Lender receives an amount equal to the sum it would have received had no such
 deductions or withholdings been made, (ii) the Borrower shall make such
 deductions or withholdings, and (iii) the Borrower shall pay the full
 amount deducted or withheld to the relevant taxation authority or other
 authority in accordance with applicable law. If any Tax, including, without
 limitation, any withholding tax, of the United States of America or any other
 Governmental Authority shall be or become applicable (y) after the date
 of this Agreement, to such payments by the Borrower made to the Lending Installation
 or any other office that Lender may claim as its Lending Installation, or
 (z) after Lender’s selection and designation of any other Lending
 Installation, such payments made to such other Lending Installation, Lender
 shall use reasonable efforts to make, fund and maintain its Loans through
 another Lending Installation of Lender in another jurisdiction so as to
 reduce the Borrower’s liability hereunder, if the making, tending or
 maintenance of such Loans through such other Lending Installation of Lender
 does not, in the reasonable judgment of such Lender, otherwise adversely and
 materially affect such Loans, or obligations under the Revolving Loan
 Commitments of such Lender.

 
	
  

 	
  

 
	
  

 	
                     (ii)     In
 addition, the Borrower agrees to pay any present or future stamp or
 documentary taxes or any other excise or property taxes, charges, or similar
 levies which arise from any payment made hereunder, from the issuance of
 Letters of Credit hereunder, or from the execution, delivery or registration of,
 or otherwise with respect to, this Agreement, the other Loan Documents, the
 Revolving Loan Commitments, the Loans or the Letters of Credit (hereinafter
 referred to as “Other Taxes”).

 
	
  

 	
  

 
	
  

 	
                     (iii)    The
 Borrower indemnifies Lender for the full amount of Taxes and Other Taxes
 (including, without limitation, any Taxes or Other Taxes imposed by any
 Governmental Authority on amounts payable under this Section 2.14(E))
 paid by Lender or the Lender and any liability (including penalties, interest,
 and expenses) arising therefrom or with respect thereto, whether or not such
 Taxes or Other Taxes were correctly or legally asserted. This indemnification
 shall be made within thirty (30) days

 after the date Lender makes written demand therefor. A certificate as
 to any additional amount payable to Lender under this Section 2.14(E)
 submitted to the Borrower by Lender shall show in reasonable detail the
 amount payable and the calculations used to determine such amount and shall,
 absent manifest error, be final, conclusive and binding upon all parties
 hereto. With respect to such deduction or withholding for or on account of
 any Taxes and to confirm that all such Taxes have been paid to the
 appropriate Governmental Authorities, the Borrower shall promptly (and in any
 event not later than thirty (30) days after receipt) furnish to Lender
 certificates, receipts and other documents as may be required (in the
 judgment of Lender to establish any tax credit to which Lender may be
 entitled. In the event Lender receives any such tax credit, Lender shall pay
 to the Borrower such amount (if any) not exceeding the increased amount paid
 by the Borrower to, or on behalf of, Lender that is allocable to such
 increased amount. Lender requesting compensation under this Section 2.14(E)
 shall use its reasonable efforts to notify the Borrower in writing of the
 event giving rise to such demand for compensation not more than
 ninety (90) days following the date upon which the responsible account
 officer for the Lender knows of such event. Such written demand shall be
 rebuttably presumed correct for all purposes. If Lender demands compensation
 under this Section 2.14(E) more than ninety (90) days
 following the date upon which a responsible account officer for Lender knows
 that Taxes or Other Taxes have begun to accrue with respect to which Lender
 is entitled to compensation under this Section 2.14(E), then any
 Taxes or Other Taxes attributable to the period prior to the ninety (90)
 day period immediately preceding the date on which Lender provided such
 notice and demand for compensation shall be excluded from the indemnity
 obligations of the Borrower under this Section 2.14(E).

 
	
  

 	
  

 
	
  

 	
                     (iv)     Within
 thirty (30) days after the date of any payment of Taxes or Other Taxes
 by the Borrower, the Borrower shall furnish to the Lender the original or a
 certified copy of a receipt evidencing payment thereof.

 
	
  

 	
  

 
	
  

 	
                     (v)      Without
 prejudice to the survival of any other agreement of the Borrower hereunder,
 the agreements and obligations of the Borrower contained in this Section 2.14(E)
 shall survive the payment in full of all Obligations hereunder, the
 termination of the Letters of Credit and the termination of this Agreement
 for a period of one year.

 
	
  

 	
  

 
	
  

 	
                     (vi)     Upon
 the request, and at the expense of the Borrower, the Lender to which the
 Borrower is required to pay any additional amount pursuant to this Section 2.14(E),
 shall reasonably afford the Borrower the opportunity to contest, and shall
 reasonably cooperate with the Borrower in contesting, the imposition of any
 Tax giving rise to such payment; provided, that (i) Lender shall
 not be required to afford the Borrower the opportunity to so contest unless
 the Borrower shall have confirmed in writing to Lender its obligation to pay
 such amounts pursuant to this Agreement; and (ii) the Borrower shall
 reimburse Lender for its attorneys’ and accountants’ fees and disbursements
 incurred in so cooperating with the Borrower in contesting the imposition of
 such Tax; provided, however, that notwithstanding the
 foregoing, Lender shall not be

 required to afford the Borrower the opportunity to contest, or
 cooperate with the Borrower in contesting, the imposition of any Taxes, if
 Lender in good faith determines that to do so would have an adverse effect on
 it.

 

                    2.14     Lending Installations.
Lender may book its Loans or Letters of Credit at any Lending Installation
selected by Lender and may change its Lending Installation from time to time
upon reasonable written notice thereof to the Borrower. All terms of this
Agreement shall apply to any such Lending Installation. Lender may, by written
or facsimile notice to the Borrower, designate a Lending Installation through
which Loans will be made by it and for whose account Loan payments and/or
payments of L/C Obligations are to be made.

                    2.15     Termination Date.
This Agreement shall be effective until the Termination Date. Notwithstanding
the termination of this Agreement, until (A) all of the Obligations (other
than contingent indemnity obligations) shall have been fully paid and satisfied
in cash, (B) all financing arrangements among the Borrower and the Lender
pursuant to this Agreement shall have been terminated and (C) all of the
Letters of Credit shall have expired, been canceled, terminated or cash
collateralized in accordance with Section 3.11, all of the rights
and remedies under this Agreement and the other Loan Documents shall survive.

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

                    2.17     Security of Obligations.
As security for the payment of the Obligations, and each Guarantor’s Obligation
under its Subsidiary Guaranty, the Borrower and each Guarantor, pursuant to the
terms of the Security Agreement, Collateral Assignment, Alabama Leasehold
Mortgage, the Subsidiary Stock Pledge Agreements, Trademark Security Agreement,
Patent Security Agreement, Indiana Mortgage, Pennsylvania Mortgage and
California Deed of Trust, as applicable, do hereby reaffirm its pledge,
assignment, transfer and delivery to the Lender and grant to the Lender a
continuing and unconditional security interest in and to the Collateral as
defined herein. The Lender and the Borrower agree that the Lender shall release
its security interest and liens in the Collateral upon Borrower’s delivery and
Lender’s

acceptance, of Borrower’s notice of its satisfaction of and compliance
with the Release Covenants, in the form required by Section 7.1(J).

Lender shall have no obligation to and shall not:

                    (A)     issue
(or amend) any Letter of Credit if on the date of issuance (or amendment),
before or after giving effect to the Letter of Credit requested hereunder,
(i) the Dollar Amount of the Revolving Credit Obligations at such time
would exceed the Revolving Loan Commitment at such time, or (ii) the
aggregate outstanding Dollar Amount of the L/C Obligations would exceed the
maximum Letter of Credit Obligation; or

                    (B)     issue
(or amend) any Letter of Credit which has an expiration date later than the
date which is the earlier of (x) one (1) year after the date of
issuance thereof or (y) five (5) Business Days immediately preceding

subject to the satisfaction in full of the following conditions:

                    (A)     the
Borrower shall have delivered to the Lender at such times and in such manner as
Lender may reasonably prescribe, a request for issuance of such Letter of
Credit in substantially the form of Exhibit B hereto (each such
request a “Request For Letter of Credit”), duly executed applications for
such Letter of Credit and such letter of credit agreement as required by
Lender, and such other documents, instructions and agreements as may be
required pursuant to the terms thereof (all such applications, documents,

any conflict in terms between this Agreement and the L/C 

38

LaSalle Bank

April 20, 2005 

Page 39

Documents, this Agreement’s terms shall govern) and the proposed Letter
of Credit shall be reasonably satisfactory to Lender as to form and content;
and

                    (B)     as
of the date of issuance no order, judgment or decree of any court, arbitrator
or Governmental Authority shall purport by its terms to enjoin or restrain the
applicable Lender from issuing such Letter of Credit and no law, rule or
regulation applicable to such Lender and no request or directive (whether or
not having the force of law) from a Governmental Authority with jurisdiction
over Lender shall prohibit or request that Lender refrain from the issuance of
Letters of Credit generally or the issuance of that Letter of Credit.

                    (C)     In
the event of any conflict between the terms of this Agreement and the terms of
any application for a Letter of Credit, the terms of this Agreement shall
control.

                    3.5     Procedure for Issuance of
Letters of Credit.

                    (A)     Subject
to the terms and conditions of this Article III and provided that
the applicable conditions set forth in Sections 5.1 and 5.2
hereof have been satisfied, the Lender shall, on the requested date, issue a
Letter of Credit on behalf of the Borrower in accordance with Lender’s usual
and customary business practices and, in this connection, Lender may, assume
that the applicable conditions set forth in Section 5.2 hereof have
been satisfied unless Lender has knowledge that the applicable conditions have
not been met.

                    (B)     Lender
shall not extend or amend any Letter of Credit unless the requirements of this Section 3.5
are met as though a new Letter of Credit was being requested and issued.

                    3.6     Reimbursement Obligation.
The Borrower agrees unconditionally, irrevocably and absolutely to pay
immediately to the Lender, the amount of each advance drawn under or pursuant
to a Letter of Credit or an L/C Draft related thereto (such obligation of the
Borrower to reimburse the Lender for an advance made under a Letter of Credit
or L/C Draft being hereinafter referred to as a “Reimbursement Obligation”
with respect to such Letter of Credit or L/C Draft), each such reimbursement to
be made by the Borrower no later than the Business Day on which the Lender
makes payment of each such L/C Draft or, if the Borrower shall have received
notice of a Reimbursement Obligation later than 11:00 a.m. (Chicago time),
on any Business Day or on a day which is not a Business Day, no later than
11:00 a.m. (Chicago time), on the immediately following Business Day or,
in the case of any other draw on a Letter of Credit, the date specified in the
demand of Lender. If the Borrower at any time fails to repay a Reimbursement
Obligation pursuant to this Section 3.7, the Borrower shall be
deemed to have elected to borrow a Revolving Loan from the Lender, as of the
date of the advance giving rise to the Reimbursement Obligation, equal in
amount to the Dollar Amount of the unpaid Reimbursement Obligation. Such
Revolving Loan shall be made as of the date of the payment giving rise to such
Reimbursement Obligation, automatically, without notice and without any
requirement to satisfy the conditions precedent otherwise applicable to an
Advance of Revolving Loans. Such Revolving Loans shall constitute a Floating
Rate Advance, the proceeds of which Advance shall be used to repay such
Reimbursement Obligation. If, for any reason, the Borrower fails to repay a
Reimbursement Obligation on the day such 

39

LaSalle Bank
National Association 

April 20, 2005 

Page 40

Reimbursement Obligation arises and, for any reason, the Lender is
unable to make or has no obligation to make Revolving Loan, then such
Reimbursement Obligation shall bear interest from and after such day, until
paid in full, at the interest rate applicable to a Floating Rate Advance plus
two percent (2.0%) per annum.

                    3.7     Letter of Credit Fees.
The Borrower agrees to pay:

                    (A)     quarterly,
in arrears, to the Lender a letter of credit fee at a rate per annum equal to
the Applicable Eurodollar Margin in effect on the average daily outstanding
Dollar Amount available for drawing under each standby Letter of Credit;

                    (B)     quarterly,
in arrears, to the Lender, a letter of credit fronting fee equal to 0.125% per
annum on the average daily outstanding face amount available for drawing under
each standby Letter of Credit issued by Lender; and

                    (C)     to
the Lender, all customary fees and other issuance, amendment. cancellation,
document examination, negotiation, transfer and presentment expenses and
related charges in connection with the issuance, amendment, cancellation,
presentation of L/C Drafts, negotiation, transfer and the like customarily
charged by such Lender with respect to standby Letters of Credit, payable at
the time of invoice of such amounts.

                    3.8     Indemnification;
Exoneration.

                    (A)     In
addition to amounts payable as elsewhere provided in this Article III,
the Borrower hereby agrees to protect, indemnify, pay and save harmless the
Lender from and against any and all liabilities and costs which the Lender may
incur or be subject to as a consequence, direct or indirect, of (i) the
issuance of any Letter of Credit other than to the extent resulting from its
gross negligence or willful misconduct, as determined by the final judgment of
a court of competent jurisdiction, or (ii) the failure of the Lender to
honor a drawing under a Letter of Credit as a result of any act or omission,
whether rightful or wrongful, of any present or future de jure or de facto
Governmental Authority (all such acts or omissions herein called “Governmental
Acts”).

                    (B)     As
among the Borrower and the Lender, the Borrower assumes all risks of the acts
and omissions of, or misuse of such Letter of Credit by, the beneficiary of any
Letter of Credit. In furtherance and not in limitation of the foregoing,
subject to the provisions of the Letter of Credit applications and Letter of
Credit reimbursement agreements executed by the Borrower at the time of request
for any Letter of Credit, the Lender shall not be responsible (in the absence
of gross negligence or willful misconduct in connection therewith, as determined
by the final judgment of a court of competent jurisdiction): (i) for the
form, validity, sufficiency, accuracy, genuineness or legal effect of any
document submitted by any party in connection with the application for and
issuance of a Letter of Credit, even if it should in fact prove to be in any or
all respects invalid, insufficient, inaccurate, fraudulent or forged;
(ii) for the validity or sufficiency of any instrument transferring or
assigning or purporting to transfer or assign a Letter of Credit or the rights
or benefits thereunder or proceeds thereof, in whole or in part, which may
prove to be invalid or ineffective for any reason; (iii) for failure of
the beneficiary of a Letter of 

40

LaSalle Bank
National Association 

April 20, 2005 

Page 41

Credit to comply duly with conditions required in order to draw upon
such Letter of Credit; (iv) for errors, omissions, interruptions or delays
in transmission or delivery of any messages, by mail, cable, telegraph, telex,
or other similar form of teletransmission or otherwise; (v) for errors in
interpretation of technical trade terms; (vi) for any loss or delay in the
transmission or otherwise of any document required in order to make a drawing
under any Letter of Credit or of the proceeds thereof; (vii) for the
misapplication by the beneficiary of a Letter of Credit of the proceeds of any
drawing under such Letter of Credit; and (viii) for any consequences
arising from causes beyond the control of the Lender, including, without
limitation, any Governmental Acts. None of the above shall affect, impair, or
prevent the vesting of any Lender’s rights or powers under this Section 3.9.

                    (C)     In
furtherance and extension and not in limitation of the specific provisions
hereinabove set forth, any action taken or omitted by Lender under or in
connection with the Letters of Credit or any related certificates shall not, in
the absence of gross negligence or willful misconduct, as determined by the
final judgment of a court of competent jurisdiction, put the Lender under any
resulting liability to the Borrower or relieve the Borrower of any of its
obligations hereunder to any such Person.

                    (D)     Without
prejudice to the survival of any other agreement of the Borrower hereunder, the
agreements and obligations of the Borrower contained in this Section 3.9
shall survive the payment in full of principal and interest hereunder, the
termination of the Letters of Credit and the termination of this Agreement.

                    (E)     Cash
Collateral. Notwithstanding anything to the contrary herein or in any
application for a Letter of Credit, following the occurrence and during the
continuance of a Default or upon payout or termination of this Agreement in
full in cash, the Borrower shall, on the Business Day that it receives Lender’s
demand, deliver to the Lender, cash, or other collateral of a type satisfactory
to the Lender, having a value, as determined by Lender, equal to one hundred
five percent (105%) of the aggregate Dollar Amount of the outstanding L/C
Obligations. Any such collateral shall be held by the Lender in a separate
account appropriately designated as a cash collateral account in relation to
this Agreement and the Letters of Credit and retained by the Lender as collateral
security for the Borrower’s obligations in respect of this Agreement and each
of the Letters of Credit. Such amounts shall be applied to reimburse the Lender
for drawings or payments under or pursuant to Letters of Credit, or if no such
reimbursement is required, to payment of such of the other Obligations as the
Lender shall determine. Amounts remaining in any cash collateral account
established pursuant to this Section 3.9 which are not to be
applied to reimburse Lender for amounts actually paid or to be paid by Lender
in respect of a Letter of Credit. shall be returned to the Borrower within
one (1) Business Day (after deduction of the Lender’s expenses incurred in
connection with such cash collateral account).

     ARTICLE IV: CHANGE
IN CIRCUMSTANCES

                    4.1     Yield Protection. If
any law or any governmental or quasi-governmental rule, regulation, policy,
guideline or directive (whether or not having the force of law) adopted after
the date the Lender became a party to this Agreement and having general
applicability to all banks within the jurisdiction in which Lender operates
(excluding, for the avoidance of 

41

LaSalle Bank
National Association 

April 20, 2005 

Page 42

doubt, the effect of and phasing in of capital requirements or other
regulations or guidelines passed prior to the date of this Agreement), or any
interpretation or application thereof by any Governmental Authority charged
with the interpretation or application thereof, or the compliance of any Lender
therewith,

	
  

 	
  

 
	
  

 	
           (A)     subjects
 Lender or any applicable Lending Installation to any tax, duty, charge or
 withholding on or from payments due from the Borrower (excluding taxation of
 the overall net income of Lender or taxation of a similar basis, which are
 governed by Section 2.13(E), and excluding any other taxes for
 which Lender has been reimbursed by the Borrower), or changes the basis of
 taxation of payments to Lender in respect of its Revolving Loan Commitment,
 Loans, the Letters of Credit or other amounts due it hereunder, or

 
	
  

 	
  

 
	
  

 	
           (B)     imposes
 or increases or deems applicable any reserve, assessment, insurance charge,
 special deposit or similar requirement against assets of, deposits with or for
 the account of, or credit extended by, Lender or any applicable Lending
 Installation (other than reserves and assessments taken into account in
 determining the interest rate applicable to Eurodollar Rate Loans) with
 respect to its Revolving Loan Commitment, the Loans, or the Letters of
 Credit, or

 
	
  

 	
  

 
	
  

 	
           (C)     imposes
 any other condition the result of which is to increase the cost to Lender or
 any applicable Lending Installation of making, funding or maintaining its
 Revolving Loan Commitment, the Loans, or the Letters of Credit or reduces any
 amount receivable by Lender or any applicable Lending Installation in
 connection with Loans or Letters of Credit, or requires Lender or any
 applicable Lending Installation to make any payment calculated by reference
 to the amount of its Revolving Loan Commitment, the Loans or the L/C
 Interests held or interest received by it or by reference to the Letters of
 Credit, by an amount deemed material by Lender;

 

and the result of any of the foregoing is to increase the cost to
Lender of making, renewing or maintaining its Revolving Loan Commitment, Loans,
L/C Interests, or Letters of Credit or to reduce any amount received under this
Agreement, then, within fifteen (15) days after receipt by the Borrower of
written demand by Lender pursuant to Section 4.5, the Borrower
shall pay Lender that portion of such increased expense incurred or reduction
in an amount received which such Lender determines is attributable to making,
funding and maintaining its Loans, L/C Interests, Letters of Credit, and its
Revolving Loan Commitment; provided, however, that the Borrower
shall not be required to pay any additional amounts pursuant to this Section 4.1
incurred more than 90 days prior to the date of the relevant Lender’s
demand therefor.

                    4.2     Changes in Capital
Adequacy Regulations. If Lender determines (i) the amount of capital
required to be maintained by Lender, any Lending Installation of such Lender or
any corporation controlling such Lender is increased as a result of a “Change”
(as defined below), and (ii) such increase in capital will result in an
increase in the cost to Lender of maintaining its Revolving Loan Commitment,
the Loans, L/C Interests, the Letters of Credit or its obligation to make Loans
hereunder, then, within fifteen (15) days after receipt by the Borrower of
written demand by Lender pursuant to Section 4.5, the Borrower
shall pay Lender 

42

LaSalle Bank
National Association 

April 20, 2005 

Page 43

the amount necessary to compensate for any shortfall in the rate of
return on the portion of such increased capital which Lender determines is
attributable to this Agreement, its Loans, its L/C Interests, the Letters of
Credit or its obligation to make Loans hereunder (after taking into account
such Lender’s policies as to capital adequacy); provided, however,
that the Borrower shall not be required to pay any additional amounts pursuant
to this Section 4.2 incurred more than 90 days prior to the
date of Lender’s demand therefor. “Change” means (i) any change
after the date the Lender became a party to this Agreement in the “Risk-Based
Capital Guidelines” (as defined below) excluding, for the avoidance of doubt,
the effect of any phasing in of such Risk-Based Capital Guidelines or any other
capital requirements passed prior to the date hereof, or (ii) any adoption
of or change in any other law, governmental or quasi- governmental rule,
regulation, policy, guideline, interpretation, or directive (whether or not
having the force of law) after the date the Lender became a party to this Agreement
and having general applicability to all banks and financial institutions within
the jurisdiction in which Lender operates which affects the amount of capital
required or expected to be maintained by Lender or any Lending Installation or
any corporation controlling any Lender. “Risk- Based Capital Guidelines”
means (i) the risk-based capital guidelines in effect in the United States
on the date the Lender became a party to this Agreement, including transition
rules, and (ii) the corresponding capital regulations promulgated by
regulatory authorities outside the United States implementing the July 1988
report of the Basle Committee on Banking Regulation and Supervisory Practices
Entitled “International Convergence of Capital Measurements and Capital
Standards,” including transition rules, and any amendments to such regulations
adopted prior to the date the Lender became a party to this Agreement.

                    4.3     Availability of Types of
Advances. If (i) Lender determines, in the exercise of its business
judgment, that maintenance of its Fixed-Rate Rate Loans at a suitable Lending
Installation would violate any applicable law, rule, regulation or directive,
whether or not having the force of law, or (ii) the Lender determines that
(x) deposits of a type, currency or maturity appropriate to match fund
Fixed-Rate Loans are not available or (y) the interest rate applicable to
Fixed-Rate Loans does not accurately reflect the cost of making or maintaining
such an Advance, then the Lender shall suspend the availability of the affected
Type of Advance and, in the case of any occurrence set forth in clause (i),
require any Advances of the affected Type to be repaid or converted into
another Type.

                    4.4     Funding Indemnification.
Subject to Section 2.3(B), if any payment of a Fixed-Rate Loan
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment, or otherwise, or a Fixed-Rate Loan
is not made on the date specified by the Borrower for any reason other than
default by the Lender, the Borrower shall indemnify Lender for any loss or cost
incurred by it resulting therefrom, including, without limitation, any loss or
cost in liquidating or employing deposits acquired to fund or maintain the
Fixed-Rate Loan.

                    4.5     Lender Statements;
Survival of Indemnity. If reasonably possible, Lender shall designate an
alternate Lending Installation with respect to its Fixed-Rate Loans to reduce
any liability of the Borrower to Lender under Section 2.14(E) or Sections 4.1
and 4.2 or to avoid the unavailability of a Type of Advance under Section 4.3,
so long as such designation is not 

43

LaSalle Bank
National Association 

April 20, 2005 

Page 44

materially disadvantageous, in the judgment of the Lender, to such
Lender. Any demand for compensation pursuant to Section 2.14(E) or
this Article IV shall be in writing and shall state the amount due,
if any, under Section 2.14(E), 4.1, 4.2, or 4.4
and shall set forth in reasonable detail the calculations upon which Lender
determined such amount and shall be final, conclusive, and binding on the
Borrower in the absence of manifest error. Determination of amounts payable
under such Sections in connection with a Fixed-Rate Loan shall be calculated as
though Lender funded its Fixed-Rate Loan through the purchase of a deposit of
the type, currency and maturity corresponding to the deposit used as a
reference in determining the Eurodollar Rate applicable to such Loan, whether
in fact that is the case or not. The obligations of the Borrower under Sections 2.14(E),
4.1, 4.2, or 4.4 shall survive payment of the Obligations
and termination of this Agreement. 

     ARTICLE V:
CONDITIONS PRECEDENT

                    5.1     Initial Advances and
Letters of Credit. The Lender shall not be required to make the Loans as of
the Closing Date or issue any Letters of Credit unless the Borrower has
furnished to the Lender each of the following, all in form and substance
satisfactory to the Lender:

	
  

 	
  

 
	
  

 	
                     (1)     The
 Amended and Restated Credit Agreement, duly executed by Borrower, each
 Subsidiary Guarantor and Lender;

 
	
  

 	
  

 
	
  

 	
                     (2)     Revolving
 Loan Note, payable to Lender’s order in the amount of the Revolving Loan
 Commitment;

 
	
  

 	
  

 
	
  

 	
                     (3)     Secretary’s

                    5.2     Each Advance and Letter

exists no Default or Unmatured Default;

                    (B)     The

date); and

                    (C)     The

contained in Sections 5.2(A), (B) and (C) have been
satisfied.

     ARTICLE VI: REPRESENTATIONS AND WARRANTIES

                    In
order to induce the Lender to enter into this Agreement and to make the Loans

thereafter on each date as required by Section 5.2:

                    6.1     Organization; Corporate
Powers. The Borrower (i) is a corporation duly organized, validly existing
and in good standing under the laws of the jurisdiction of its organization,
(ii) is duly qualified to do business as a foreign entity and is in good
standing under the laws of each jurisdiction in which failure to be so
qualified and in good standing would reasonably be expected to have a Material
Adverse Effect, and (iii) has all requisite power and authority to own,
operate and encumber its property and to conduct its business as presently
conducted and as proposed to be conducted.

                    6.2     Authority;

otherwise to which the Borrower or any of its Subsidiaries is party, and the
consummation of the transactions contemplated thereby, have been duly
authorized by all requisite corporate, acts (including any required shareholder

                    (C)     Each

and delivered by it and constitutes its legal, valid and binding obligation, enforceable

creditors’ rights generally and general equitable principles).

                    6.3     No Conflict;

result in a breach of or constitute (with or without notice or lapse of time or
both) a default under any Requirement of Law (including, without limitation,
any Environmental Property Transfer Act) or Contractual Obligation of the
Borrower, or require termination of any Contractual Obligation, except such
breach, default or termination which individually or in the aggregate could not

property or assets of the Borrower, other than Liens permitted or created by
the Loan Documents. Except as set forth on Schedule 6.3 to this
Agreement, the execution, delivery and performance of each of the Loan
Documents to which the Borrower is a party do not and will not require any
registration with, consent or approval of or notice to, or other action to,
with or by any Governmental Authority, including under any Environmental Property
Transfer Act, except filings, consents or notices which have been made,
obtained or given, or which, if not made, obtained or given, individually or in

Effect.

date such statements were prepared and fairly present the consolidated
financial condition and operation of the Borrower and its Subsidiaries at June
30, 2004 or for the applicable date or period and the consolidated results of
their operations for the period then ended.

                    6.5     No Material Adverse

confidential offering memorandum delivered by the Borrower to the Lender prior

                    6.6     Taxes. Each of the
Borrower and its Subsidiaries has filed or caused to be filed all federal,
state and local tax returns which are required to be filed by it and, except
for taxes and assessments being contested in good faith and reserved for in
accordance with generally accepted accounting principles as in effect from time
to time (if and to the extent so required), have paid or caused to be paid all
taxes as shown on said returns on any assessment received by it, to the extent
that such taxes have become due. The Borrower has no knowledge of any proposed
tax assessment against the Borrower or any of its Subsidiaries that will have
or could reasonably be expected to have a Material Adverse Effect.

                    6.7     Litigation; Loss
Contingencies and Violations. Except as disclosed on Schedule 6.7, there is
no action, suit, proceeding, arbitration or, to the Borrower’s knowledge,
investigation before or by any Governmental Authority or private arbitrator
pending or, to the Borrower’s knowledge, threatened in writing against the
Borrower, any of its Subsidiaries or any property of any of them which could
reasonably be expected to have a Material Adverse Effect.

                    6.8     Subsidiaries. Schedule 6.8
to this Agreement (as updated from time to time by the Borrower after the
formation, acquisition or dissolution of any Subsidiary (i) contains a
description of the corporate structure of the Borrower, its Subsidiaries and
any other Person in which the Borrower or any of its Subsidiaries holds an
Equity Interest; and (ii) accurately sets forth (A) the correct legal
name and the jurisdiction of organization, (B) a listing of all of the
Borrower’s or any Domestic Incorporated Subsidiary’s Significant Domestic
Incorporated Subsidiaries, (C) the authorized, issued and outstanding
shares of each class of Capital Stock of each of the Borrower’s Subsidiaries
and the owners of such shares, and (D) a summary of the direct and indirect
partnership, joint venture, or other Equity Interests, if any, which the
Borrower and each Subsidiary of the Borrower holds in any Person that is not a
corporation. Except as disclosed on Schedule 6.8, none of the
issued and outstanding Capital Stock of the Borrower or any of the Borrower’s
Subsidiaries is subject to any vesting, redemption, or repurchase agreement,
and there are no warrants or options outstanding with respect to such Capital
Stock. The outstanding Capital Stock of each of the Borrower’s Subsidiaries is
duly authorized, validly issued, fully paid and nonassessable and is not Margin
Stock.

                    6.9     ERISA. Except as
disclosed on Schedule 6.9, no Benefit Plan has incurred any
material accumulated funding deficiency (as defined in Sections 302(a)(2)
of ERISA and 412(a) of the Code) whether or not waived. Neither the Borrower
nor any member of the Controlled Group has incurred any material liability to
the PBGC which remains outstanding other than the payment of premiums. As of
the last day of the most recent prior plan year, the market value of assets
under each Benefit Plan, other than any Multiemployer Plan, was not by a
material amount less than the present value of benefit liabilities thereunder
(determined in accordance with the actuarial valuation assumptions described
therein). Neither the Borrower nor any member of the Controlled Group has
(i) failed to make a required contribution or payment to a Multiemployer
Plan of a material amount or (ii) incurred a material complete or partial
withdrawal under Section 4203 or Section 4205 of ERISA from a
Multiemployer Plan. Neither the Borrower nor any member of the Controlled Group
has failed 

50

LaSalle Bank
National Association 

April 20, 2005 

Page 51

to make an installment or any other payment of a material amount
required under Section 412 of the Code on or before the due date for such
installment or other payment. There have been no and there is no prohibited
transaction described in Sections 406 of ERISA or 4975 of the Code with
respect to any Plan for which a statutory or administrative exemption does not
exist which could reasonably be expected to subject the Borrower or any of is
Subsidiaries to material liability. Neither the Borrower nor any member of the
Controlled Group has taken or failed to take any action which would constitute
or result in a Termination Event, which action or inaction could reasonably be
expected to subject the Borrower or any of its Subsidiaries to material
liability. Neither the Borrower nor any member of the Controlled Group is
subject to any material liability under, or has any potential material
liability under, Section 4063, 4064, 4069, 4204 or 4212(c) of ERISA. For
purposes of this Section 6.9, “material” means any amount,
noncompliance or other basis for liability which could reasonably be expected
to subject the Borrower or any of its Subsidiaries to liability, individually
or in the aggregate with each other basis for liability under this Section 6.9,
in excess of $3,000,000.

                    6.10     Accuracy of Information.
The information, exhibits and reports furnished by the Borrower and any of its
Subsidiaries, or by the Borrower on behalf of any of its Subsidiaries, to the
Lender in connection with the negotiation of, or compliance with, the Loan
Documents, the representations and warranties of the Borrower and its
Subsidiaries contained in the Loan Documents, and all certificates and
documents delivered to the Lender pursuant to the terms thereof (excluding any
forecasts and projections of financial information and results submitted to
Lender as works in process or as materials not otherwise required to be
submitted to the Commission), taken as a whole, do not contain as of the date
thereof any untrue statement of a material fact or omit to state a material
fact necessary in order to make the statements contained herein or therein, in
light of the circumstances under which they were made, not misleading in any
material respect.

                    6.11     Securities Activities.
Neither the Borrower nor any of its Subsidiaries is engaged in the business of
extending credit for the purpose of purchasing or carrying Margin Stock.

                    6.12     Material Agreements.

                    (a)        Neither
the Borrower nor any Subsidiary is a party to or subject to any Contractual
Obligation, which, as of such date, individually or in the aggregate could
reasonably be expected to have a Material Adverse Effect.

                    (b)        No
member of the senior management of either the Borrower or any of its
Subsidiaries has received written notice that (i) it is in default in the
performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in any Contractual Obligation to which it is a party, or
(ii) any condition exists which, with the giving of notice or the lapse of
time or both, would constitute a default with respect to any such Contractual
Obligation, in each case, which default has, or if not remedied within any
applicable grace period could reasonably be likely to have, a Material Adverse
Effect.

                    6.13     Compliance with Laws.
The Borrower and its Subsidiaries are in compliance with all Requirements of
Law applicable to them and their respective businesses, in each case where the
failure to so comply individually or in the aggregate would reasonably be
expected to have a Material Adverse Effect.

                    6.14     Assets and Properties.
Each of the Borrower and its Subsidiaries has good and sufficient title to all
of its material real and personal properties owned by it or a valid leasehold
interest in all of its leased assets (except insofar as marketability may be
limited by any laws or regulations of any Governmental Authority affecting such
assets), and all such assets and property are free and clear of all Liens,
except Liens permitted under Section 7.3(C), and except for those
defects in title and Liens that, individually or in the aggregate, would not
have a Material Adverse Effect.

                    6.15     Statutory Indebtedness
Restrictions. Neither the Borrower nor any of its Subsidiaries is subject
to regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, or the Investment Company Act of 1940, or any other foreign, federal
or state statute or regulation which limits its ability to incur indebtedness
or its ability to consummate the transactions contemplated hereby.

                    6.16     Labor Matters. To
the knowledge of the Borrower, no attempt to organize the employees of the
Borrower or any of its Subsidiaries, and no labor disputes, strikes or walkouts
affecting the operations of the Borrower or any of its Subsidiaries, is
pending, or, to the Borrower’s or such Subsidiaries’ knowledge, threatened,
planned or contemplated which would reasonably be expected to have a Material
Adverse Effect.

                    6.17     Environmental Matters.

                    (A)       Except
as disclosed on Schedule 6.17 to this Agreement:

	
  

 	
  

 
	
  

 	
                       (i)     the
 operations of the Borrower and its Subsidiaries comply in all material
 respects with Environmental, Health or Safety Requirements of Law;

 
	
  

 	
  

 
	
  

 	
                     
 (ii)     the Borrower and its Subsidiaries have all

other applicable laws, and the regulations and interpretations thereunder and
the respective requirements of the governing documents for such Plans and
Non-ERISA Commitments, unless the failure to maintain, operate and comply with
the foregoing, as applicable, would not reasonably be expected to subject
Borrower or its Subsidiaries to a liability in excess of $3,000,000. 

                    (H)     Maintenance
of Property. The Borrower shall cause all material property used in the

shall cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Borrower
may be necessary so that the business carried on in connection therewith may be
properly conducted at all times; provided, however, that nothing in this Section
7.2(H) shall prevent the Borrower from discontinuing the operation or
maintenance of any of such property if such discontinuance is, in the judgment
of the Borrower, desirable in the conduct of its business or the business of
any Subsidiary. 

                    (I)     Environmental
Compliance. The Borrower and its Subsidiaries shall comply with all Environmental,
Health or Safety Requirements of Law, except where noncompliance will not have
or is not reasonably likely to subject the Borrower or any of its Subsidiaries
to liability, individually or in the aggregate, in excess of $3,000,000. 

                    (J)     Use

or carry any Margin Stock.

Guarantees. The Borrower will, including in connection with a Permitted
Acquisition, (a) cause each Significant Domestic Incorporated Subsidiary or
Significant Foreign Incorporated Subsidiary to execute the Subsidiary Guaranty
(and from and after the Closing Date cause each Significant Domestic
Incorporated Subsidiary or Significant Foreign Incorporated Subsidiary or any
other Subsidiary designated a Subsidiary Guarantor by Borrower, to execute and
deliver to the Lender, as promptly as possible, but in any event within sixty
(60) days after becoming a Significant Domestic Incorporated Subsidiary or
Significant Foreign Incorporated Subsidiary of the Borrower or being designated
a Subsidiary Guarantor by Borrower, as applicable, an executed Supplement to
become a Subsidiary Guarantor under the Subsidiary Guaranty in the form of
Annex I to Exhibit Z attached hereto (whereupon such Subsidiary shall
become a “Subsidiary Guarantor” under this Agreement)), and (b) deliver and
cause each such Subsidiary to deliver corporate resolutions, opinions of
counsel, and such other corporate documentation as the Lender may reasonably
request, all in form and substance reasonably satisfactory to the Lender; provided,
however, that upon the Borrower’s written request of and certification
to the Lender that a Domestic Incorporated Subsidiary or Significant Foreign
Incorporated Subsidiary is no longer a Significant Domestic Incorporated
Subsidiary or Significant Foreign Incorporated Subsidiary or that a designated
Subsidiary Guarantor is no longer designated as a Subsidiary Guarantor, the
Lender shall release such Domestic Incorporated Subsidiary, Significant Foreign
Incorporated Subsidiary or designated Subsidiary from its duties and
obligations under the Subsidiary Guaranty; provided, further,
that if such Domestic Incorporated Subsidiary or Significant Foreign
Incorporated Subsidiary subsequently qualifies as a Significant Domestic
Incorporated Subsidiary or Significant Foreign Incorporated Subsidiary, it
shall be required to re-execute the Subsidiary Guaranty. Notwithstanding the
above to the contrary, with respect to a Significant Foreign Incorporated
Subsidiary (or a Subsidiary that is not a Domestic Incorporated Subsidiary but
is designated as a Subsidiary Guarantor), Borrower may deliver, in lieu of a
Subsidiary Guaranty, a pledge agreement, in form and substance acceptable to
the Lender, pledging no more than sixty-five percent (65%) of the voting stock
of such Subsidiary to the Lender.

 proceeds resulting from an Asset Sale are used by the Borrower or the
applicable Subsidiary within 180 days of the date on which such proceeds

 Officers, demonstrating to the reasonable satisfaction of the Lender that
 after giving effect to such Acquisition and the incurrence of any Indebtedness

 basis using, for any Acquisition, historical financial statements, as if the
 Acquisition and such incurrence of Indebtedness had occurred on the first day
 of the twelve-month period ending on the last day of the Borrower’s most
 recently completed fiscal quarter, the Borrower would have been in compliance
 with the financial covenants in Section 7.4 applicable on such date
 and not otherwise in Default;

 
	
  

 	
  

 
	
  

 	
                     (iv)     after
 giving effect to such Acquisition, Borrower must demonstrate pro forma

property or the rendering of any service) with any Affiliate of the Borrower,
on terms that are (a) not authorized by the Board of Directors or (b) less

Borrower into the Borrower or another Subsidiary of the Borrower, as
applicable.

                    (J)     Margin
Regulations. Neither the Borrower nor any of its Subsidiaries, shall use

 waived;

 
	
  

 	
  

 
	
  

 	
                     (ii)      terminate,
 or permit any Controlled Group member to terminate, any Benefit Plan which

                     (iii)     fail,
 or permit any Controlled Group member to fail, to pay any required
 installment or any other payment required under Section 412 of the Code on or
 before the due date for such installment or other payment;

not, individually or in the aggregate, reasonably expected to result in
liability individually or in the aggregate in excess of $3,000,000.

                    (L)     Domestic
Incorporated Subsidiary Covenants. The Borrower will not, and will not
permit any Domestic Incorporated Subsidiary to, create or otherwise cause to
become effective any consensual encumbrance or restriction of any kind on the
ability of any Domestic

Incorporated Subsidiary to pay dividends or make any other distribution
on its stock, or make any other Restricted Payment, pay any Indebtedness or
other Obligation owed to the Borrower or any other Domestic Incorporated

Subsidiaries to enter into any interest rate, commodity or foreign currency
exchange, swap, collar, cap or similar agreements evidencing Hedging
Obligations, other than interest rate, foreign currency or commodity exchange,
swap, collar, cap or similar agreements entered into by the Borrower or such
Subsidiary pursuant to which the Borrower or such Subsidiary has hedged its
reasonably estimated interest rate, foreign currency or commodity exposure,
which are non-speculative in nature. Such permitted hedging agreements shall be
entered into by the Borrower only with Lender or any affiliate of the Lender
and are herein referred to as “Hedging Agreements.”

                    10.13     Subordination of Intercompany Indebtedness. The Borrower
agrees that any and all claims of the Borrower against any of its Subsidiary
Guarantors with respect to any indebtedness of any Subsidiary Guarantor to the
Borrower (“Intercompany Indebtedness”), any endorser, obligor or any
other Subsidiary Guarantor of all or any part of the Obligations, or against
any of its properties, including, without limitation, claims arising from liens
or security interests upon property, shall be subordinate and subject in right
of payment to the prior payment, in full and in cash, of all Obligations: provided
that, and not in contravention of the foregoing, so long as no Default has
occurred and is continuing the Borrower may make loans to and receive payments
in the ordinary course with respect to such Intercompany Indebtedness from each
such Subsidiary Guarantor to the extent permitted by the terms of this
Agreement and the other Loan Documents. Should any payment, distribution,
security or instrument or proceeds thereof be received by the Borrower upon or
with respect to the Intercompany Indebtedness in contravention of this
Agreement or the Loan Documents or after the occurrence of a Default,
including, without limitation, an event described in Section 8.1(F) or (G)
prior to the satisfaction of all of the Obligations (other than contingent
indemnity obligations) and the termination of all financing arrangements
pursuant to any Loan Document or Hedging Agreement among the Borrower and the
Lender (and its Affiliates), the Borrower shall receive and hold the same in
trust, as trustee, for the benefit of the holders of the Obligations and shall
forthwith deliver the same to the Lender, for the benefit of such Persons, in
precisely the form received (except for the endorsement or assignment of the
Borrower where necessary), for application to any of the Obligations, due or
not due, and, until so delivered, the same shall be held in trust by the
Borrower as the property of the holders of the Obligations. If the Borrower fails
to make any such endorsement or assignment to the Lender, the Lender or any of
its officers or employees are irrevocably authorized to make the same. The
Borrower agrees that until the Obligations involving the payment of monies
(other than the contingent indemnity obligations) have been paid in full (in
cash) and satisfied and all financing arrangements pursuant to any Loan
Document or Hedging Agreement among the Borrower and the Lenders (and its
Affiliates) have been terminated, the Borrower will not assign or transfer to
any Person (other than the Lender) any claim the Borrower has or may have
against any Subsidiary Guarantor.

                    10.14     Assignability. The Lender may at any time assign the
Lender rights in this Agreement, the Note, the Obligations, or any part thereof
and transfer the Lender’s rights in any or all of the Collateral, and the
Lender thereafter shall be relieved from all liability with respect to such
Collateral. In addition, the Lender may at any time sell one or more
participations in the Loans. The Borrower may not sell or assign this
Agreement, or any other agreement with the Lender or any portion thereof,
either voluntarily or by operation of law, without the prior written consent of
the Lender. This Agreement shall be binding upon the Lender and the Borrower
and their respective legal representatives and successors. All references
herein to the Borrower shall be deemed to include any successors, whether
immediate or remote.

                    10.15     Customer Identification-USA Patriot Act Notice. The
Lender hereby notifies the Borrower that pursuant to the requirements of the
USA Patriot Act (Title III of Pub. L. 107-56, signed into law October 26, 2001)
(the “Act”), and the Lender’s policies and practices, the Lender is required to
obtain, verify and record certain information and documentation that identifies
the Borrower, which information includes the name and address of the Borrower
and 

77

LaSalle Bank

Page 78

such other information that will allow the Lender to identify the
Borrower in accordance with the Act. 

     ARTICLE XI: SETOFF, RATABLE PAYMENTS

                    11.1    Setoff. In addition to, and without limitation of, any
rights of the Lender under applicable law, if any Default occurs and is
continuing, any Indebtedness from Lender to the Borrower (including all account
balances, whether provisional or final and whether or not collected or
available) may be offset and applied toward the payment of the Obligations
owing to Lender, whether or not the Obligations, or any part hereof, shall then
be due. Notwithstanding the foregoing, at any time that any Obligations are
secured by real property located in California, Lender shall not exercise a
right of setoff, banker’s lien or counterclaim or take any court or
administrative action or institute any proceeding to enforce any provision of
this Agreement or any Obligation that is not taken by the Lender if such setoff
or action or proceeding would or might (pursuant to the Collateral Documents or
the enforceability of the Obligations, and any attempted exercise by any Lender
of any such right shall be null and void. This Section shall be solely for the
benefit of each of the Lender hereunder.

                    11.2    Application of Payments. If the Borrower, prior to the
occurrence of a Default, has remitted a payment to the Lender without
indicating the Obligation to be reduced thereby, or at any time after the
occurrence of a Default, subject to the provisions of Section 9.2, the
Lender shall apply all payments and prepayments in respect of any Obligations
in the following order:

                    (A)     first,
to pay Obligations in respect of any fees, expenses, reimbursements or
indemnities then due to the Lender;

                    (B)     second,
to pay interest due in respect of Revolving Loans and L/C Obligations;

                    (C)     third,
to the payment or prepayment of principal outstanding on Revolving Loans and
Reimbursement Obligations in such order as the Lender may determine in its sole
discretion;

                    (D)     fourth,
to provide required cash collateral, if required pursuant to Section 3.11;
and

                    (E)     fifth,
to the payment of all other Obligations.

Unless otherwise designated (which designation shall only be applicable prior to the
occurrence of a Default) by the Borrower, all principal payments in respect of
Loans shall be applied first, to repay outstanding Floating Rate Loans, and then
to repay outstanding Eurodollar Rate Loans with those Eurodollar Rate Loans
which have earlier expiring Interest Periods being repaid prior to those which
have later expiring Interest Periods.

Attention: Stephanie Kline, Vice President

                              Re:     Quixote
Corporation

Ladies and
Gentlemen:

                    I
am counsel for Quixote Corporation, a Delaware corporation (the “Borrower”) and
each of those subsidiaries of the Borrower identified on Schedule 1 to
this opinion (each individually, a “Subsidiary Guarantor”, and collectively,
the “Subsidiary Guarantors”), in connection with the transactions contemplated
by that certain Amended and Restated Credit Agreement dated as of April 20,
2005 (as amended, modified or supplemented, the “Credit Agreement”), among
Borrower and LaSalle Bank National Association, as Lender (“Lender”). Unless
otherwise indicated, capitalized terms used herein without definition shall
have the respective meanings set forth in the Credit Agreement.

                    In
writing this opinion and delivering it to you, I am acting in my capacity as
Vice President and General Counsel of Borrower. In so acting, I have
participated in the negotiation of, and have examined the Credit Agreement and
the other documents identified on Schedule 2 to this Opinion (the
“Opinion Documents”).

                    I
have also examined the originals, or copies certified or otherwise identified
to my satisfaction, of such records, documents, certificates and other
instruments as in my judgment are necessary or appropriate to enable me to render
the opinion expressed below. I have relied, to the extent that I deem such
reliance appropriate, upon certificates and other statements of officers and
employed counsel of Borrower, and of public officials issued with respect to
Borrower and the Subsidiary Guarantors, as well as upon searches of public
records provided to me, as specifically described below. 

                    I
have assumed the genuineness of all signatures. I have also assumed the
authority and legal capacity of all persons executing documents on behalf of
persons other than the Borrower or the Subsidiary Guarantors, and the
authenticity of all documents submitted to me as originals, and the conformity
to original documents of all documents submitted to me as certified or
photostatic copies.

85

LaSalle Bank
National Association

April 20, 2005

Page 86

                    Based
upon the foregoing, I am of the opinion that:

                    1.          Borrower
is a corporation duly organized and existing and in good standing under the
laws of the State of Delaware and has the corporate power to own its properties
and to carry on its business as presently conducted by it, and is in good
standing as a foreign corporation in each jurisdiction where the failure to be
so qualified would have a material adverse effect on Borrower.

                    2.          Borrower
has the requisite corporate power and authority to execute and deliver the
Credit Agreement, the Revolving Note and the Security Document Assignments and
Security Document Reaffirmations and Amendments (as defined on Schedule 2)
to which it is a party, and to perform the obligations set forth in the Credit
Agreement, the Revolving Note and each of the Security Document Assignments and
Security Document Reaffirmations and Amendments executed by it, each of which
has been duly authorized by all necessary corporate action. The execution and
performance by Borrower of the Credit Agreement, the Revolving Note and each of
the Security Document Assignments and Security Document Reaffirmations and
Amendments to which it is a party will not violate Borrower’s Certificate of
Incorporation or Bylaws, or result in a material violation of any of the terms,
conditions or provisions of any applicable law or regulation or, to the best of
my knowledge and belief, any order, writ, injunction or decree of any court or
governmental authority, or result in a breach of any of the terms, conditions
or provisions of any material contract to which Borrower is a party or by which
Borrower is bound.

                    3.          Each
Subsidiary Guarantor is a corporation duly organized and existing and in good
standing under the laws of its jurisdiction of organization identified in Schedule
1 to this opinion letter and has the corporate power to own its properties
and to carry on its business as presently conducted by it, and is in good
standing as a foreign corporation in each jurisdiction where the failure to be
so qualified would have a material adverse effect on that Subsidiary Guarantor.

                    4.          Each
Subsidiary Guarantor has the requisite corporate power and authority to execute
and deliver the Credit Agreement and each of the Security Document Assignments
and Security Document Amendments to which it is a party and to perform the
obligations set forth in the Credit Agreement and each of the Security Document
Assignments and Security Document Reaffirmations and Amendments to which it is
a party, which has been duly authorized by all necessary corporate action. The
execution and performance of the Credit Agreement and each of the Security
Document Assignments and Security Document Reaffirmations and Amendments to
which it is a party by each Subsidiary Guarantor will not violate the
respective Subsidiary Guarantor’s certificate of incorporation or bylaws (or
other equivalent organizational documents) or result in a material violation of
any of the terms, conditions or provisions of any applicable law or regulation
or, to the best of my knowledge and belief, any order, writ, injunction or
decree of any court or governmental authority, or result in a breach of any of
the terms, conditions or provisions of any material contract to which the
Subsidiary Guarantor is a party or by which the Subsidiary Guarantor is bound.

                    5.          Spin-Cast
Plastics, Inc. has the requisite corporate power and authority to execute and
deliver the Indiana Mortgage and to perform the obligations set forth in the
Indiana 

86

LaSalle Bank
National Association

April 20, 2005

Page 87

Mortgage, which has been duly authorized by all necessary corporate
action. The execution and performance of the Indiana Mortgage by Spin-Cast
Plastics, Inc. will not violate Spin-Cast Plastics, Inc.’s certificate of
incorporation or bylaws (or other equivalent organizational documents) or
result in a material violation of any of the terms, conditions or provisions of
any applicable law or regulation or, to the best of my knowledge and belief, no
order, writ, injunction or decree of any court or governmental authority, or
result in a material breach of any of the terms, conditions or provisions of
any material contract to which Spin-Cast Plastics, Inc. is a party or by which
Spin-Cast Plastics, Inc. is bound.

                    6.          Based
solely on: (i) a review of my litigation files, (ii) a review of the litigation
docket for the Borrower and its Subsidiary Guarantors, and (iii) a docket
search of the United States District Court for the Northern District of
Illinois, there are no judgments outstanding against Borrower or any Subsidiary
Guarantor nor is there now pending or, to my knowledge, threatened, any
material action, suit or proceeding before any court of any governmental or
regulatory authority, by, against or involving Borrower or any Subsidiary
Guarantor, except as disclosed in Schedule 6.7 to the Credit Agreement, in each
case as amended by the information provided in any report or notice delivered
by Borrower to the Lender pursuant to Section 7.1 of the Credit Agreement. None
of the Borrower or the Subsidiary Guarantors is in violation of any order,
writ, injunction or decree of any court, or in violation in any material
respect of any applicable law, order, regulation or demand or any governmental
agency or instrumentality, a default under which would substantially and
materially adversely affect the condition (financial or otherwise) of Borrower,
or its ability to perform its obligations under the Credit Agreement, the
Revolving Note and each of the Security Document Assignments and Security
Document Reaffirmations and Amendments to which it is a party; or the condition
(financial or otherwise) of any Subsidiary Guarantor or its ability to perform
its obligations under each of the Credit Agreement and the Security Document
Assignments and Security Document Reaffirmations and Amendments to which it is
a party; or the ability of Spin-Cast Plastics, Inc. to perform its obligations
under the Indiana Mortgage.

                    7.          There
is no default by Borrower under any material contract to which the Borrower is
a party, which has, or would have, a material and adverse effect upon the
financial condition of Borrower. There is no default by a Subsidiary Guarantor
under any material contract to which that Subsidiary Guarantor is a party,
which has, or would have, a material and adverse effect upon the financial
condition of that Subsidiary Guarantor.

                    8.          The
Credit Agreement, the Revolving Note and each of the Security Document
Assignments and Security Document Reaffirmations and Amendments to which it is
a party have been duly executed and delivered by a duly authorized officer of
Borrower and constitute the valid and binding obligations of Borrower,
enforceable in accordance with their respective terms, except as enforceability
may be limited by bankruptcy, insolvency, reorganization, moratorium or other
similar laws relating to or effecting the enforcement of creditors’ rights,
generally, and general principles of equity, as applicable. The Credit
Agreement and each of the Security Document Assignments and Security Document
Reaffirmations and Amendments have been duly executed and delivered by a duly
authorized officer of each Subsidiary Guarantor which is a party to that

obligations of each such Subsidiary Guarantor, enforceable in
accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws relating
to or effecting the enforcement of creditors’ rights generally, and general
principles of equity, as applicable. The Indiana Mortgage has been duly
executed and delivered by a duly authorized officer of Spin-Cast Plastics, Inc.
and it constitutes the valid and binding obligations of Spin-Cast Plastics,
Inc. enforceable in accordance with its terms, except as enforceability may be
limited by bankruptcy, insolvency, reorganization, moratorium or other similar
laws relating to or effecting the enforcement of creditors’ rights generally,
and general principles of equity, as applicable. 

                    9.          No
consent or approval of or, other action by, any United States federal or state
regulatory authority or other person or entity, which has not been obtained or
taken, is required for the execution, delivery or performance of the Credit
Agreement, the Revolving Note and each of the Security Document Assignments and
Security Document Reaffirmations and Amendments by Borrower or any Subsidiary Guarantor,
as applicable.

                    10.          Under
choice of law principles applicable under Illinois law, the provisions of the
Credit Agreement (i) stating that Illinois law shall govern the enforcement of
the Credit Agreement, and (ii) stating that the loans and advances made under
the Credit Agreement, together with the interest on such loans and advances,
will be governed by the internal laws of the State of Illinois, are each enforceable so
long as the court finds that (i) Illinois bears a reasonable relationship to
the transaction contemplated by the Credit Agreement, and (ii) the enforcement
of the Credit Agreement in accordance with Illinois law is not dangerous,
inconvenient, immoral or contrary to public policy. 

                    I
am a member of the bar of the State of Illinois and therefore express no
opinion with respect to any matter (and except as expressly provided in
Paragraph 10 above, including conflict of laws and choice of law issues) which
may be governed by the laws of any jurisdiction other than the State of
Illinois, the corporation laws of the State of Delaware and applicable laws of
the United States of America.

                    I
have not reviewed and do not opine as to: (i) compliance with applicable
zoning, health, safety, building, environmental, land use or subdivision laws,
ordinances, codes, rules or regulations, (ii) ERISA laws, rules and
regulations, (iii) Federal or state taxation, banking, securities or “blue sky”
laws, rules or regulations, or (iv) local law, ordinances or regulations.

                    This
opinion letter is being furnished to the Lender for its use and the use of its
counsel in connection with the transactions contemplated by the Credit
Agreement. I understand and acknowledge that you are relying on the opinion set
forth herein in entering into the

EXHIBIT L

MORTGAGE AND SECURITY AGREEMENT

                    THIS
MORTGAGE AND SECURITY AGREEMENT (“Mortgage”),
made as of April 20, 2005, is made and executed by Spin-Cast Plastics, Inc., an
Indiana corporation, having its principal offices at 3300 North Kenmore Street,
South Bend, Indiana 46628 (“Mortgagor”),
in favor of LASALLE BANK NATIONAL ASSOCIATION, a national banking association
having an office at 135 South LaSalle Street, Chicago, Illinois 60603 (“Lender”).

RECITALS

                              I.     Lender
has agreed to make loans to Quixote Corporation, a Delaware corporation (“Borrower”) and extend other financial
accommodations to Borrower in an aggregate principal amount of $30,000,000
(collectively, the “Loans”). The
Loans consist of one or more revolving loans (the “Revolving Loan”), the outstanding principal balance of which
may increase or decrease from time to time, but at no time shall the
outstanding principal balance of such Revolving Loan exceed $30,000,000. Certain repayment obligations of Borrower
with respect to the Revolving Loan are evidenced by a certain Revolving Note,
in the principal amount of $30,000,000 (said note, together with all allonges,
amendments, supplements, modifications and replacements thereof, being referred
to in this Mortgage as the “Revolving Note”).
The Revolving Note is sometimes referred to herein as the “Note.” The terms of the Loans are governed
by a certain Amended and Restated Credit and Security Agreement, of even date herewith (amending and restating the
terms of the Credit Agreement dated, as of May 16, 2003, as amended)
by and between Borrower and Lender (said Credit Agreement, together with all
amendments, supplements, modifications and replacements thereof, being referred
to in this Mortgage as the “Loan Agreement”).
The terms and provisions of the Note and the Loan Agreement are hereby
incorporated by reference in this Mortgage. Capitalized terms not otherwise
defined in this Mortgage shall have the meaning ascribed to them in the Loan
Agreement. As an inducement to Lender to make the Loan, Mortgagor has executed
and delivered to Lender the Loan 

37

LaSalle Bank National Association

April 20, 2005

Page 38

Agreement, as a Subsidiary Guarantor thereunder, to evidence its
becoming a Subsidiary Guarantor, as defined in the Loan Agreement, under that
certain Subsidiary Guaranty (the “Guaranty”)
of even date herewith, pursuant to which Mortgagor has agreed to guaranty all
of the indebtedness and obligations of Borrower owed to Lender, including
without limitation the obligations of Borrower with respect to the Loan.

                              II.     This
Mortgage is given to secure a guaranty of one or more revolving loans and
secures not only present indebtedness but also future advances, whether such
future advances are obligatory or are to be made at the option of Lender, or
otherwise as are to be made within five (5)
years of the date hereof. The amount of indebtedness secured hereby
may increase or decrease from time to time; however the principal amount of
such indebtedness shall not at one time exceed the amount of $30,000,000 plus
interest thereon, and other costs, amounts and disbursements as provided
herein and in the other Loan Instruments (hereinafter defined).

GRANTING CLAUSES

hereafter executed and delivered in connection with the Loan, and any and all

ARTICLE ONE

COVENANTS OF MORTGAGOR

                    Mortgagor
covenants and agrees with Lender as follows:

                    1.1.     Performance
under Guaranty, Mortgage and Other Loan Instruments. Mortgagor shall perform, observe and comply
with or cause to be performed, observed and complied with in a complete and
timely manner all provisions hereof and of the Guaranty, every other Loan

                    1.2.     General
Covenants and Representations. Mortgagor covenants, represents and warrants that as of the date
hereof and at all times thereafter during the term hereof: (a) Mortgagor is a
corporation, duly organized, validly existing and in good standing under the
laws of the State of Indiana [and is in good standing under the laws of the
State of Illinois;] (b) Mortgagor is seized of an indefeasible estate in fee
simple in that portion of the Mortgaged Property which is real property, and
has good and absolute title to it and the balance of the Mortgaged Property
free and clear of all liens, security interests, charges and encumbrances
whatsoever except those expressly permitted in writing by Lender, if any (such
liens, security interests, charges and encumbrances expressly permitted in
writing being hereinafter referred to as the “Permitted
Encumbrances”); (c) Mortgagor has good right, full power and lawful
authority to mortgage and pledge the Mortgaged Property as provided herein; (d)
upon the occurrence of an Event of Default, Lender may at all times peaceably
and quietly enter upon, hold, occupy and enjoy the Mortgaged Property in
accordance with the terms hereof; and (e) Mortgagor will maintain and preserve
the lien of this Mortgage as a first and paramount lien on the Mortgaged
Property subject only to the Permitted Encumbrances until Mortgagor’s
Liabilities have been paid in full.

environmental laws and regulations and all other applicable laws, ordinances,
rules and regulations. If any federal, state or other governmental body or any
court issues any notice or order to the effect that the Mortgaged Property or
any part thereof is not in compliance with any such covenant, ordinance, code,
law or regulation, Mortgagor will promptly provide Lender with a copy of such
notice or order and will immediately commence and diligently perform all such
actions as are necessary to comply therewith or otherwise correct such
non-compliance. Mortgagor shall not, without the prior written consent of
Lender, petition for or otherwise seek any change in the zoning ordinances or

                    1.4.     Taxes
and Other Charges.

                    1.4.1. 
Taxes and Assessments. Mortgagor shall pay promptly
when due all taxes, assessments, rates, dues, charges, fees, levies, fines,
impositions, liabilities, obligations, liens and encumbrances of every kind and
nature whatsoever now or hereafter imposed, levied or assessed upon or against
the Mortgaged Property or any part thereof, or upon or against this Mortgage or
Mortgagor’s Liabilities or upon or against the interest of Lender in the
Mortgaged Property, as well as all taxes, assessments and other governmental
charges levied and imposed by the United States of America or any state,
county, municipality or other taxing authority upon or in respect of the
Mortgaged Property or any part thereof; provided, however, that unless
compliance with applicable laws requires that taxes, assessments or other
charges must be paid as a condition to protesting or contesting the amount
thereof, Mortgagor may in good faith, by appropriate proceedings commenced
within ninety (90) days of the due date of such amounts and thereafter
diligently pursued, contest the validity, applicability or amount of any
asserted tax, assessment or other charge and pending such contest Mortgagor
shall not be deemed in default hereunder if on or before the due date of the
asserted tax or assessment, Mortgagor shall first either (i) deposit with
Lender a bond or other security satisfactory to Lender in the amount of 150% of
the amount of such tax or assessment or (ii) obtain an endorsement, in form and
substance satisfactory to Lender, to the loan policy of title insurance issued
to Lender insuring the lien of this Mortgage, insuring over such tax or
assessment. Mortgagor shall pay the disputed or contested tax, assessment or
other charge and all interest and penalties due in respect thereof on or before
the date any adjudication of the validity or amount thereof becomes final and
in any event no less than thirty (30) days prior to any forfeiture or sale of
the Mortgaged Property by reason of such non-payment. Upon Lender’s request,
Mortgagor will promptly file, if it has not theretofore filed, such petition,
application or other instrument as is necessary to cause the Land and Improvements
to be taxed as a separate parcel or parcels which include no property not a
part of the Mortgaged Property.

                    1.4.2. 
Taxes Affecting Lender’s Interest. If any state,
federal, municipal or other governmental law, order, rule or regulation, which
becomes effective subsequent to the date hereof, in any manner changes or
modifies existing laws governing the taxation of mortgages or debts secured by
mortgages, or the manner of collecting taxes, so as to impose on Lender a tax
by reason of its ownership of any or all of the Loan Instruments or measured by
the principal amount of the Notes, requires or has the practical effect of
requiring Lender to pay any portion of the real estate taxes levied in respect
of the Mortgaged Property to pay any tax levied in whole or in part in
substitution for real estate taxes or otherwise affects materially and
adversely the rights of Lender in respect of the Notes, this Mortgage or the
other Loan Instruments, Mortgagor’s Liabilities and all interest accrued
thereon shall, upon thirty (30) days’ notice, become due and payable forthwith
at the option of Lender, whether 

42

LaSalle Bank National Association

April 20, 2005

Page 43

or not there shall have occurred an Event of Default, provided,
however, that, if Mortgagor may, without violating or causing a violation of
such law, order, rule or regulation, pay such taxes or other sums as are
necessary to eliminate such adverse effect upon the rights of Lender and does
pay such taxes or other sums when due, Lender may not elect to declare due
Mortgagor’s Liabilities by reason of the provisions of this Section 1.4.2.

                    1.4.3. 
Tax Escrow. If directed by Lender in writing,
Mortgagor shall, in order to secure the performance and discharge of
Mortgagor’s obligations under this Section 1.4, but not in lieu of such
obligations, deposit with Lender on the first day of each calendar month
throughout the term of the Loan, deposits, in amounts set by Lender from time
to time by written notice to Mortgagor, in order to accumulate funds sufficient
to permit Lender to pay all annual ad valorem taxes, assessments and charges of
the nature described in Section 1.4.1 at least thirty (30) days prior to the
date or dates on which they shall become delinquent. Mortgagor hereby pledges
to Lender, and grants to Lender a security interest in, any and all such
deposits as security for the Loan. The taxes, assessments and charges for
purposes of this Section 1.4.3 shall, if Lender so elects, include, without
limitation, water and sewer rents. Mortgagor shall procure and deliver to
Lender when issued all statements or bills for such obligations. Upon demand by
Lender, Mortgagor shall deliver to Lender such additional monies as are
required to satisfy any deficiencies in the amounts necessary to enable Lender
to pay such taxes, assessments and similar charges thirty (30) days prior to
the date they become delinquent. Lender shall pay such taxes, assessments and
other charges as they become due to the extent of the funds on deposit with
Lender from time to time and provided Mortgagor has delivered to Lender the
statements or bills therefor. In making any such payments, Lender shall be
entitled to rely on any bill issued in respect of any such taxes, assessments
or charges without inquiry into the validity, propriety or amount thereof and
whether delivered to Lender by Mortgagor or otherwise obtained by Lender. Any
deposits received pursuant to this Section 1.4.3 shall not be, nor be deemed to
be, trust funds, but may be commingled with the general funds of Lender and
Lender shall have no obligation to pay interest on amounts deposited with
Lender pursuant to this Section 1.4.3. If any Event of Default occurs, any part
or all of the amounts then on deposit or thereafter deposited with Lender under
this Section 1.4.3 may at Lender’s option be applied to payment of Mortgagor’s
Liabilities in such order as Lender may determine.

                    1.4.4. 
No Credit Against the Indebtedness Secured Hereby.
Mortgagor shall not claim, demand or be entitled to receive any credit against
the amounts payable under the terms of the Guaranty or on any of Mortgagor’s
Liabilities for any of the taxes, assessments or similar impositions assessed
against the Mortgaged Property or any part thereof or that are applicable to
Mortgagor’s Liabilities or to Lender’s interest in the Mortgaged Property.

                    1.5      Mechanic’s
and Other Liens. Mortgagor shall not permit or suffer any mechanic’s, laborer’s, materialman’s,
statutory or other lien or encumbrance (other than any lien for taxes and
assessments not yet due) to be created upon or against the Mortgaged Property,
provided, however, that Mortgagor may in good faith, by appropriate proceeding,
contest the validity, applicability or amount of any asserted lien and, pending
such contest, Mortgagor shall not be deemed to be in default hereunder if
Mortgagor shall first obtain an endorsement, in form and substance satisfactory
to Lender, to the loan policy of title insurance issued to Lender insuring over
such lien, or, if no such loan policy shall have been issued, then Mortgagor
shall deposit with Lender a bond or other security satisfactory to Lender in
the amount of 150% of the amount of such lien. Mortgagor shall pay the disputed
amount and all interest and penalties due in respect thereof on or before the
date any adjudication of the validity or amount thereof becomes final and, in
any event, no less than thirty (30) days prior to any foreclosure sale of the
Mortgaged Property or the exercise of any other remedy by such claimant against
the Mortgaged Property.

                    1.6      Insurance
and Condemnation.

                    1.6.1. 
Hazard Insurance. Mortgagor shall, at its sole cost
and expense, obtain for, deliver to, assign to and maintain for the benefit of
Lender, until Mortgagor’s Liabilities are paid in full, policies of hazard
insurance, in an amount which shall be not less than 100% of the full insurable
replacement cost of the Mortgaged Property (except the Land), insuring on a
replacement cost basis the Mortgaged Property with “causes of loss-special
form” coverage and insuring against such other hazards, casualties and
contingencies as Lender may require, including without limitation, if requested
by Lender, earthquake, and, if all or any part of the Mortgaged Property shall
at any time be located within an area identified by the government of the
United States or any agency thereof as having special flood hazards and for
which flood insurance is available, flood. If any such policy shall contain a
co-insurance clause it shall also contain an agreed amount or stipulated value
endorsement. All policies of hazard insurance shall contain a “lender’s loss
payable” endorsement and shall provide that no losses shall be payable to any
other parties without Lender’s prior written consent. The form of such
policies, the amounts and the companies issuing them shall be acceptable to
Lender. Originals or certified copies of all policies shall be delivered to and
retained by Lender. Mortgagor shall pay on or before the due dates thereof
premiums on all insurance policies and on any renewals thereof. In the event of
loss, Mortgagor will give immediate written notice to Lender and Lender may
make proof of loss if not made promptly by Mortgagor (for which purpose
Mortgagor hereby irrevocably appoints Lender as its attorney-in-fact). In the
event of the foreclosure of this Mortgage or any other transfer of title to the
Mortgaged Property in full or partial satisfaction of Mortgagor’s Liabilities,
all right, title and interest of Mortgagor in and to all insurance policies and
renewals thereof then in force shall pass to the purchaser

or grantee. All such policies shall provide that they shall not be
modified, cancelled or terminated without at least thirty (30) days’ prior
written notice to Lender from the insurer.

                    1.6.2.   Other
Insurance. Mortgagor shall, at its sole cost and
expense, obtain for, deliver to, assign to and maintain for the benefit of,
Lender, until Mortgagor’s Liabilities are paid for in full, (i) commercial
general liability insurance in such amounts as Lender may specify, together
with workers compensation and employer’s liability insurance, naming Lender as
additional insured, [(ii) a business interruption insurance policy covering
loss of rents [loss of income] at
a limit of 100%, in an amount not less than all rent and other charges payable
by the tenants of the Mortgaged Property [gross
income] (based on a fully leased [fully
operational] building) for a period of one (1) year, together with
such assignments of the proceeds of such policy as Lender may require,] (iii)
boiler and machinery insurance, if requested by Lender, and (iv) such other
policies of insurance relating to the Mortgaged Property and the use and
operation thereof as Lender may require, including dramshop, all in form and
amounts, and issued by such companies as are acceptable to Lender.

                    1.6.3.   Adjustment
of Loss. Lender is hereby authorized and empowered, at
its option, to adjust or compromise any loss of more than $250,000 under any
insurance policies covering or relating to the Mortgaged Property and to
collect and receive the proceeds from any such policy or policies (and deposit
such proceeds as provided in Section 1.6.5). Mortgagor hereby irrevocably appoints
Lender as its attorney-in-fact for the purposes set forth in the preceding
sentence. Each insurance company is hereby authorized and directed to make
payment (i) of 100% of all such losses of more than said amount directly to
Lender alone and (ii) of 100% of all such losses of said amount or less
directly to Mortgagor alone, and in no case to Mortgagor and Lender jointly.
After deducting from such insurance proceeds any expenses incurred by Lender in
the collection and settlement thereof, including without limitation attorneys’
and adjusters’ fees and charges, Lender shall apply the net proceeds as
provided in Section 1.6.5. Lender shall not be responsible for any failure to
collect any insurance proceeds due under the terms of any policy regardless of
the cause of such failure.

                    1.6.4.   Condemnation
Awards. Lender shall be entitled to all compensation,
awards, damages, claims, rights of action and proceeds of, or on account of,
(i) any damage or taking, pursuant to the power of eminent domain, of the
Mortgaged Property or any part thereof, (ii) damage to the Mortgaged Property
by reason of the taking, pursuant to the power of eminent domain, of other
property, or (iii) the alteration of the grade of any street or highway on or
about the Mortgaged Property. Lender is hereby authorized, at its option, to
commence, appear in and prosecute in its own or Mortgagor’s name any action or
proceeding relating to any such compensation, awards, damages, claims, rights
of action and proceeds and to settle or compromise any claim in connection
therewith. Mortgagor hereby irrevocably appoints Lender as its attorney-in-fact
for the purposes set forth in the preceding sentence. Lender after deducting
from such compensation, awards, damages, claims, 

45

LaSalle Bank National Association

rights of action and proceeds all its expenses, including attorneys’
fees, may apply such net proceeds (except as otherwise provided in Section
1.6.5 of this Mortgage) to payment of Mortgagor’s Liabilities in such order and
manner as Lender may elect. Mortgagor agrees to execute such further
assignments of any compensation awards, damages, claims, rights of action and
proceeds as Lender may require.

                    1.6.5.   Repair;
Proceeds of Casualty Insurance and Eminent Domain. If
all or any part of the Mortgaged Property shall be damaged or destroyed by fire
or other casualty or shall be damaged or taken through the exercise of the
power of eminent domain or other cause described in Section 1.6.4, Mortgagor
shall promptly and with all due diligence restore and repair the Mortgaged
Property whether or not the proceeds, award or other compensation are
sufficient to pay the cost of such restoration or repair. At Lender’s election,
to be exercised by written notice to Mortgagor within thirty (30) days following
Lender’s unrestricted receipt in cash or the equivalent thereof of said
proceeds, award or other compensation, the entire amount of said proceeds,
award or compensation shall either (i) be applied to Mortgagor’s Liabilities in
such order and manner as Lender may elect or (ii) be made available to
Mortgagor on such terms and conditions as Lender may impose, including without
limitation the terms and conditions set forth in this Section 1.6.5, for the
purpose of financing the cost of restoration or repair with any excess to be
applied to Mortgagor’s Liabilities. Notwithstanding any other provision of this
Section 1.6.5, if an Event of Default shall be existing at the time of such
casualty, taking or other event or if an Event of Default occurs thereafter,
Lender shall have the right to immediately apply all insurance proceeds, awards
or compensation to the payment of Mortgagor’s Liabilities in such order and
manner as Lender may determine. Lender shall have the right at all times to
apply such net proceeds to the cure of any Event of Default or the performance
of any obligations of Mortgagor under the Loan Instruments.

                    1.6.6.   [Proceeds
of Business Interruption and Rental Insurance. The net
proceeds of business interruption and rental insurance shall be paid to Lender
for application first to Mortgagor’s Liabilities in such order and manner as
Lender may elect and then to the creation of reserves for future payments of
Mortgagor’s Liabilities in such amounts as Lender deems necessary with the
balance to be remitted to Mortgagor subject to such controls as Lender may deem
necessary to assure that said balance is used to discharge accrued and to be
accrued expenses of operation and maintenance of the Mortgaged Property.]

                    1.6.7.   Renewal
of Policies. At least thirty (30) days prior to the
expiration date of any policy evidencing insurance required under this Section
1.6.7, a renewal thereof satisfactory to Lender shall be delivered to Lender or
substitution therefor, together with receipts or other evidence of the payment
of any premiums then due on such renewal policy or substitute policy.

                    1.6.8.   Insurance
Escrow. If directed by Lender in writing, Mortgagor
shall, in order to secure the performance and discharge of Mortgagor’s
obligations under this Section 1.6, but not in lieu of such obligations,
deposit with Lender on the first day of each calendar month throughout the term
of the Loan, a sum in an amount determined by Lender from time to time by
written notice to Mortgagor, in order to accumulate funds sufficient to permit
Lender to pay all premiums payable in connection with the insurance required
hereunder at least thirty (30) days prior to the date or dates on which they
shall become due. Mortgagor hereby pledges to Lender, and grants to Lender a
security interest in, any and all such deposits as security for the Loan. Upon
demand by Lender, Mortgagor shall deliver to Lender such additional monies as
are required to satisfy any deficiencies in the amounts necessary to enable
Lender to pay such premiums thirty (30) days prior to the date they shall
become due. Any deposits received pursuant to this Section 1.6.8 shall not be,
nor be deemed to be, trust funds, but may be commingled with the general funds
of Lender and Lender shall have no obligation to pay interest on amounts
deposited with Lender pursuant to this Section 1.6.8. If any Event of Default
occurs, any part or all of the amounts then on deposit or thereafter deposited
with Lender under this Section 1.6.8 may at Lender’s option be applied to
payment of Mortgagor’s Liabilities in such order as Lender may determine.

                    1.7.     Non-Impairment
of Lender’s Rights. Nothing contained in this Mortgage shall be deemed to limit or otherwise affect
any right or remedy of Lender under any provision of this Mortgage or of any
statute or rule of law to pay and, upon Mortgagor’s failure to pay the same,
Lender may pay any amount required to be paid by Mortgagor under Sections 1.4,
1.5 and 1.6 and the amount so paid by Lender shall bear interest at the Default
Rate (as defined in the Notes), and, together with interest, shall be added to
Mortgagor’s Liabilities. Mortgagor shall pay to Lender on demand the amount so
paid by Lender, together with all accrued and unpaid interest thereon. The
provisions of Section 1.4.3 are solely for the added protection of Lender and
entail no responsibility on Lender’s part beyond the allowing of due credit as
specifically provided therein. Upon assignment of this Mortgage, any funds on
hand shall be turned over to the assignee and any responsibility of Lender with
respect to such funds shall terminate.

                    1.8.     Care
of the Mortgaged Property. Mortgagor shall preserve and maintain the Mortgaged Property in good
and first class condition and repair. Mortgagor shall not, without the prior
written consent of Lender, permit, commit or suffer any waste, impairment or
deterioration of the Mortgaged Property or of any part thereof, and will not
take any action which will increase the risk of fire or other hazard to the
Mortgaged 

47

LaSalle Bank National Association

Property or to any part thereof. Except as
otherwise provided in this Mortgage, no new improvements shall be constructed
on the Mortgaged Property and no part of the Mortgaged Property shall be
removed, demolished or altered in any material manner without the prior written
consent of Lender.

                    1.9.     Transfer
or Encumbrance of the Mortgaged Property. Mortgagor shall not permit or suffer to occur
any sale, assignment, conveyance, transfer, mortgage, lease (other than leases
made in accordance with the provisions of this Mortgage) or encumbrance of, or
any contract for any of the foregoing on an installment basis or otherwise
pertaining to, the Mortgaged Property, any part thereof, any interest therein,
the beneficial interest in Mortgagor or in any trust holding title to the
Mortgaged Property or any interest in a corporation, partnership or other
entity which owns all or part of the Mortgaged Property, whether by operation
of law or otherwise, without the prior written consent of Lender having been
obtained (i) to the sale, assignment, conveyance, mortgage, lease, option,
encumbrance or other transfer and (ii) to the form and substance of any
instrument evidencing or contracting for any such sale, assignment, conveyance,
mortgage, lease, option, encumbrance or other transfer. Mortgagor shall not,
without the prior written consent of Lender, further assign or permit to be
assigned the rents from the Mortgaged Property, and any such assignment without
the prior express written consent of Lender shall be null and void. Mortgagor
shall not permit any interest in any lease of the Mortgaged Property to be
subordinated to any encumbrance on the Mortgaged Property other than the Loan
Instruments and any such subordination shall be null and void. Mortgagor agrees
that in the event the ownership of the Mortgaged Property, any interest therein
or any part thereof becomes vested in a person other than Mortgagor, Lender may,
without notice to Mortgagor, deal in any way with such successor or successors
in interest with reference to this Mortgage, the Notes, the Loan Instruments
and Mortgagor’s Liabilities without in any way vitiating or discharging
Mortgagor’s liability hereunder or Mortgagor’s Liabilities. No sale of the
Mortgaged Property, no forbearance to any person with respect to this Mortgage,
and no extension to any person of the time for payment of the Notes or any
other Mortgagor’s Liabilities given by Lender shall operate to release,
discharge, modify, change or affect the original liability of Mortgagor, either
in whole or in part, except to the extent specifically agreed in writing by
Lender. 

                    1.10.    Further
Assurances. At any
time and from time to time, upon Lender’s request, Mortgagor shall make,
execute and deliver, or cause to be made, executed and delivered, to Lender,
and where appropriate shall cause to be recorded, registered or filed, and from
time to time thereafter to be re-recorded, re-registered and refiled at such
time and in such offices and places as shall be deemed desirable by Lender, any
and all such further mortgages, security agreements, financing statements,
instruments of further assurance, certificates and other documents as Lender
may consider necessary or desirable in order to effectuate or perfect, or to
continue and preserve the obligations under, the Guaranty, this Mortgage, any
other Loan Instrument and any instrument evidencing or securing Mortgagor’s
Liabilities, and the lien of this Mortgage as a lien upon all of the Mortgaged
Property, whether now owned or hereafter

acquired by Mortgagor, and unto all and every
person or persons deriving any estate, right, title or interest under this
Mortgage. Upon any failure by Mortgagor to do so, Lender may make, execute,
record, register, file, re-record, re-register or re-file any and all such
mortgages, instruments, certificates and documents for and in the name of
Mortgagor, and Mortgagor hereby irrevocably appoints Lender the agent and
attorney-in-fact of Mortgagor to do so.

                   1.11.  Security
Agreement and Financing Statements.

	
  

 	
  

 	
  

 
	
  

 	
 (a)       Mortgagor (as debtor) hereby grants
 to Lender (as creditor and secured party) a security interest under the Uniform
 Commercial Code in all fixtures, machinery, appliances, equipment, furniture
 and personal property of every nature whatsoever constituting part of the
 Mortgaged Property. Mortgagor shall execute any and all documents, including
 without limitation financing statements pursuant to the Uniform Commercial
 Code, as Lender may request to preserve, maintain and perfect the priority of
 the first lien and security interest created hereby on property which may be
 deemed personal property or fixtures, and shall pay to Lender on demand any
 expenses incurred by Lender in connection with the preparation, execution and
 filing of any such documents. Mortgagor hereby authorizes and empowers Lender
 and irrevocably appoints Lender the agent and attorney-in-fact of Mortgagor
 to execute and file, on Mortgagor’s behalf, all financing statements and
 refilings and continuations thereof as Lender deems necessary or advisable to
 create, preserve and protect such lien. When and if Mortgagor and Lender
 shall respectively become the debtor and secured party in any Uniform
 Commercial Code financing statement affecting the Mortgaged Property (or
 Lender takes possession of personal property delivered by Mortgagor where
 possession is the means of perfection of the security interest), then, at
 Lender’s sole election, this Mortgage shall be deemed a security agreement as
 defined in such Uniform Commercial Code, and the remedies for any violation
 of the covenants, terms and conditions of the agreements herein contained
 shall be as prescribed herein or by general law, or, as to such part of the
 security which is also reflected in such financing statement, by the specific
 statutory consequences now or hereafter enacted and specified in the Uniform
 Commercial Code.

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)       Without limitation of the foregoing,
 if an Event of Default occurs, Lender shall be entitled immediately to
 exercise all remedies available to it under the Uniform Commercial Code and
 this Section 1.11. Mortgagor shall, in such event and if Lender so requests,
 assemble the tangible personal property at Mortgagor’s

 expense, at a convenient place designated by Lender. Lender may
 publicly or privately sell or otherwise dispose of such fixtures, machinery,
 appliances, equipment, furniture and personal property upon such terms and in
 such manner as Lender may require. Mortgagor shall pay all expenses incurred
 by Lender in the collection of such indebtedness, including attorneys’ fees
 and legal expenses, and in the repair of any real estate or other property to
 which any of the tangible personal property may be affixed. If any
 notification of intended disposition of any of the personal property is
 required by law, such notification shall be deemed reasonable and proper if
 given at least ten (10) days before such disposition. Any proceeds of the
 disposition of any of the personal property may be applied by Lender to the
 payment of the reasonable expenses of retaking, holding, preparing for sale
 and selling the personal property, including attorneys’ fees and legal expenses,
 and any balance of such proceeds may be applied by Lender toward the payment
 of such of Mortgagor’s Liabilities, and in such order of application, as
 Lender may from time to time elect. If an Event of Default occurs, Lender
 shall have the right to exercise and shall automatically succeed to all
 rights of Mortgagor with respect to intangible personal property subject to
 the security interest granted herein. Any party to any contract subject to
 the security interest granted herein shall be entitled to rely on the rights
 of Lender without the necessity of any further notice or action by Mortgagor.
 Lender shall not by reason of this Mortgage or the exercise of any right
 granted hereby be obligated to perform any obligation of Mortgagor with
 respect to any portion of the personal property nor shall Lender be
 responsible for any act committed by Mortgagor, or any breach or failure to
 perform by Mortgagor with respect to any portion of the personal property.

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (c)       Mortgagor and Lender agree that the
 filing of a financing statement in the records normally having to do with
 personal property shall never be construed as in any way derogating from or
 impairing the express declaration and intention of the parties hereto,
 hereinabove stated, that everything used in connection with the production of
 income from the Mortgaged Property and/or adapted for use therein and/or
 which is described or reflected in this Mortgage is, and at all times and for
 all purposes and in all proceedings, legal or equitable, shall be regarded as
 part of the real estate encumbered by this Mortgage irrespective of whether
 (i) any such item is physically attached to the Land or Improvements, (ii)
 serial numbers are used for the better identification of certain equipment
 items capable of being thus identified in a recital

 contained herein or in any list filed with Lender, or (iii) any such
 item is referred to or reflected in any such financing statement so filed at
 any time. Similarly, the mention in any such financing statement of (1)
 rights in or to the proceeds of any fire and/or hazard insurance policy, or
 (2) any award in eminent domain proceedings for a taking or for loss of
 value, or (3) Mortgagor’s interest as lessor in any present or future lease
 or rights to income growing out of the use and/or occupancy of the Mortgaged
 Property, whether pursuant to lease or otherwise, shall never be construed as
 in any way altering any of the rights of Lender as determined by this
 instrument or adversely affecting the priority of Lender’s lien granted
 hereby or by any other recorded document. Any such mention in any such
 financing statement is declared to be for the protection of Lender in the
 event any court or judge shall at any time hold with respect to clauses (1),
 (2) or (3) above, that notice of Lender’s priority of interest, to be
 effective against a particular class of persons, including, but not limited
 to, the federal government and any subdivisions or entity of the federal
 government, must be filed in the Uniform Commercial Code records.

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 1.12.     Assignment
 of Rents.

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (a)        The assignment of rents, income and
 other benefits contained in Section (G) of the Granting Clauses of this
 Mortgage shall be fully operative without any further action on the part of
 either party, and, specifically, Lender shall be entitled, at its option,
 upon the occurrence of an Event of Default hereunder, to all rents, income
 and other benefits from the Mortgaged Property, whether or not Lender takes
 possession of such property. Mortgagor hereby further grants to Lender the
 right effective upon the occurrence of an Event of Default to do any or all
 of the following, at Lender’s option: (i) enter upon and take possession of
 the Mortgaged Property for the purpose of collecting the rents, income and
 other benefits; (ii) dispossess by the usual summary proceedings any tenant
 defaulting in the payment thereof to Lender; (iii) lease the Mortgaged
 Property or any part thereof; (iv) repair, restore and improve the Mortgaged
 Property; and (v) apply the rents, income and other benefits, after payment
 of certain expenses and capital expenditures relating to the Mortgaged
 Property, on account of Mortgagor’s Liabilities in such order and manner as
 Lender may elect. Such assignment and grant shall continue in effect until
 Mortgagor’s Liabilities are paid in full, the execution of this Mortgage
 constituting and evidencing the irrevocable consent of

 Mortgagor to the entry upon and taking possession of the Mortgaged
 Property by Lender pursuant to such grant, whether or not foreclosure
 proceedings have been instituted. Neither the exercise of any rights under
 this section by Lender nor the application of any such rents, income or other
 benefits to payment of Mortgagor’s Liabilities shall cure or waive any Event
 of Default or notice provided for hereunder, or invalidate any act done
 pursuant hereto or pursuant to any such notice, but shall be cumulative of
 all other rights and remedies. Notwithstanding the foregoing, so long as no
 Event of Default has occurred or is continuing, Mortgagor shall have the
 right and authority to continue to collect the rents, income and other
 benefits from the Mortgaged Property as they become due and payable but not
 more than thirty (30) days prior to the due date thereof. The existence or
 exercise of such right of Mortgagor to collect said rents, income and other benefits
 shall not operate to subordinate this assignment to any subsequent assignment
 of said rents, income or other benefits, in whole or in part, by Mortgagor,
 and any such subsequent assignment by Mortgagor shall be subject to the
 rights of Lender hereunder. 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)        Mortgagor shall not permit any rent
 under any lease of the Mortgaged Property to be collected more than thirty
 (30) days in advance of the due date thereof and, upon any receiver, Lender,
 anyone claiming by, through or under Lender or any purchaser at a foreclosure
 sale coming into possession of the Mortgaged Property, no tenant shall be
 given credit for any rent paid more than thirty (30) days in advance of the
 due date thereof. Mortgagor shall act promptly to enforce all available remedies
 against any delinquent lessee so as to protect the interest of the lessor
 under the leases and to preserve the value of the Mortgaged Property. 

 	
  

 

                    1.13.     After-Acquired
Property. To the extent permitted by, and subject to,
applicable law, the lien of this Mortgage, including without limitation the
security interest created under Section 1.11, shall automatically attach,
without further act, to all property hereafter acquired by Mortgagor located in
or on, or attached to, or used or intended to be used in connection with, or
with the operation of, the Mortgaged Property or any part thereof. 

                    1.14.     Leases
Affecting Mortgaged Property. 

	
  

 	
  

 	
  

 
	
  

 	
 (a)        Mortgagor shall comply with and perform in a complete and timely
 manner all of its obligations as landlord under all leases affecting the
 Mortgaged Property or any part thereof. Mortgagor shall give notice to Lender
 of any default by the landlord under any lease affecting the Mortgaged
 Property promptly upon the

 occurrence of such default, but, in any event, in such time to afford
 Lender an opportunity to cure any such default prior to the tenant having any
 right to terminate the lease. Each of the leases shall contain a provision
 requiring the tenant to notify Lender of any default by landlord and granting
 an opportunity for a reasonable time after such notice to cure such default
 prior to any right accruing to the tenant to terminate such lease. Mortgagor,
 if requested by Lender, shall furnish promptly to Lender (i) original or
 certified copies of all such leases now existing or hereafter created, as
 amended from time to time, and (ii) a current rent roll in form satisfactory
 to Lender. Lender shall have the right to notify at any time and from time to
 time any tenant of the Mortgaged Property of any provision of this Mortgage. 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)        The assignment contained in Section
 (H) of the Granting Clauses shall not be deemed to impose upon Lender any of
 the obligations or duties of the landlord or Mortgagor provided in any lease.
 

 	
  

 

                    1.15.     Management
of Mortgaged Property. Mortgagor shall cause the
Mortgaged Property to be managed at all times in accordance with sound business
practice. 

                    1.16.     Execution
of Leases. Mortgagor shall not permit any leases to be
made of the Mortgaged Property or existing leases to be modified, terminated,
extended or renewed without the prior written consent of Lender. 

                    1.17     Expenses.
Mortgagor shall pay when due and payable, and otherwise on demand made by
Lender, all appraisal fees, recording fees, taxes, brokerage fees and
commissions, abstract fees, title insurance fees, escrow fees, attorneys’ fees,
court costs, documentary and expert evidence, fees of inspecting architects and
engineers, and all other costs and expenses of every character which have been
incurred or which may hereafter be incurred by Lender in connection with any of
the following: 

	
  

 	
  

 	
  

 
	
  

 	
 (a)        Any court or administrative
 proceeding involving Mortgagor, the Mortgaged Property or the Loan
 Instruments to which Lender is made a party or is subject to subpoena by
 reason of its being a holder of any of the Loan Instruments, including without
 limitation bankruptcy, insolvency, reorganization, probate, eminent domain,
 condemnation, building code and zoning proceedings;

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)        Any court or administrative
 proceeding or other action undertaken by Lender to enforce any remedy or to
 collect any indebtedness due under this Mortgage or any of the other Loan

 Instruments following a default thereunder, including without
 limitation a foreclosure of this mortgage or a public or private sale under
 the Uniform Commercial Code;

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (c)        Any remedy exercised by Lender
 following an Event of Default including foreclosure of this Mortgage and
 actions in connection with taking possession of the Mortgaged Property or
 collecting rents assigned hereby;

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (d)        Any activity in connection with any
 request by Mortgagor or anyone acting on behalf of Mortgagor that Lender
 consent to a proposed action which, pursuant to this Mortgage or any of the
 other Loan Instruments may be undertaken or consummated only with the prior
 consent of Lender, whether or not such consent is granted; or 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (e)        Any negotiation undertaken between
 Lender and Mortgagor or anyone acting on behalf of Mortgagor pertaining to
 the existence or cure of any default under or the modification or extension
 of any of the Loan Instruments. 

 	
  

 

          If
Mortgagor fails to pay said costs and expenses as above provided, Lender may
elect, but shall not be obligated, to pay the costs and expenses described in
this Section 1.17, and if Lender does so elect, then the amounts paid by Lender
shall bear interest at the Default Rate and, together with interest, shall be
added to Mortgagor’s Liabilities. Mortgagor will, upon demand by Lender,
reimburse Lender for all such expenses, together with all accrued and unpaid
interest thereon. In the event of foreclosure hereof, Lender shall be entitled
to add to the indebtedness found to be due by the court a reasonable estimate
of such expenses to be incurred after entry of the decree of foreclosure. To
the extent permitted by law, Mortgagor agrees to hold harmless Lender against
and from, and reimburse it for, all claims, demands, liabilities, losses,
damages, judgments, penalties, costs and expenses, including without limitation
attorneys’ fees, which may be imposed upon, asserted against, or incurred or
paid by it by reason of or in connection with any bodily injury or death or
property damage occurring in or upon or in the vicinity of the Mortgaged
Property through any cause whatsoever, or asserted against it on account of any
act performed or omitted to be performed hereunder, or on account of any
transaction arising out of or in any way connected with the Mortgaged Property,
this Mortgage, the other Loan Instruments or any of Mortgagor’s Liabilities. 

	
  

 	
  

 	
  

 
	
  

 	
 1.18     Lender’s Performance of Mortgagor’s Obligations.

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (a)        If Mortgagor fails to pay any tax,
 assessment, encumbrance or other imposition, or to furnish insurance
 hereunder, or to perform any other covenant, condition or term in this
 Mortgage, the Guaranty or any other Loan Instrument, Lender may, but shall
 not

 be obligated to, pay, obtain or perform the same. All payments made,
 whether such payments are regular or accelerated payments, and costs and
 expenses incurred or paid by Lender in connection therewith shall be due and
 payable immediately. The amounts so incurred or paid by Lender shall bear
 interest at the Default Rate and, together with interest, shall be added to
 Mortgagor’s Liabilities. Lender is hereby empowered to enter and to authorize
 others to enter upon the Mortgaged Property or any part thereof for the
 purpose of performing or observing any covenant, condition or term that Mortgagor
 has failed to perform or observe, without thereby becoming liable to
 Mortgagor or any person in possession holding under Mortgagor. Performance or
 payment by Lender of any obligation of Mortgagor shall not relieve Mortgagor
 of such obligation or of the consequences of having failed to perform or pay
 the same and shall not effect the cure of any Event of Default. 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)        Without limitation of the foregoing,
 unless Mortgagor provides Lender with evidence of the insurance coverage
 required by this Mortgage, Lender may purchase insurance at Mortgagors’
 expense to protect Lender’s interests in the Mortgaged Property. This
 insurance may, but need not, protect Mortgagor’s interest. The coverage that
 Lender purchases may not pay any claim that Mortgagor may make or any claim
 that is made against Mortgagor in connection with the Mortgaged Property.
 Mortgagor may later cancel any insurance purchased by Lender, but only after
 providing Lender with evidence that Mortgagor has obtained insurance as required
 by this Mortgage. If Lender purchases insurance for the Mortgaged Property,
 Mortgagor will be responsible for the costs of such insurance, including
 interest and any other charges that may be imposed in connection with the
 placement of such insurance, until the effective date of the cancellation or
 expiration of such insurance. Without limitation of any other provision of
 this Mortgage, the cost of such insurance shall be added to the indebtedness
 secured hereby. The cost of the insurance may be more than the cost of
 insurance Mortgagor may be able to obtain on its own. 

 	
  

 

                    1.19.     Payment
of Superior Liens. To the extent that Lender, after
the date hereof, pays any sum due under any provision of law or instrument or
document creating any lien superior or equal in priority in whole or in part to
the lien of this Mortgage, Lender shall have and be entitled to a lien on the
premises equal in parity with that discharged, and Lender shall be subrogated
to and receive and enjoy all rights and liens possessed, held or enjoyed by,
the holder of such lien, which shall remain in existence and 

55

LaSalle Bank

benefit Lender to secure the Guaranty, and all obligations and
liabilities secured hereby. Lender shall be subrogated, notwithstanding their
release of record, to mortgages, trust deeds, superior titles, vendors’ liens,
mechanics’ and materialmen’s liens, charges, encumbrances, rights and equities
on the Mortgaged Property to the extent that any obligation under any thereof
is paid or discharged with proceeds of disbursements or advances subject to the
Guaranty or other indebtedness secured hereby. 

                    1.20.     Use
of the Mortgaged Property. Mortgagor shall not suffer
or permit the Mortgaged Property, or any portion thereof, to be used for any
purpose other than for the purposes for which it is currently being used and,
without limitation of the foregoing, Mortgagor shall not use or permit the use
of the Mortgaged Property or any portion thereof for any unlawful purpose. 

                    1.21.     Litigation
Involving Mortgaged Property. Mortgagor shall promptly
notify Lender of any litigation, administrative procedure or proposed
legislative action initiated against Mortgagor or the Mortgaged Property or in
which the Mortgaged Property is directly or indirectly affected including any
proceedings which seek to (i) enforce any lien against the Mortgaged Property,
(ii) correct, change or prohibit any existing condition, feature or use of the
Mortgaged Property, (iii) condemn or demolish the Mortgaged Property, (iv)
take, by the power of eminent domain, any portion of the Mortgaged Property or
any property which would damage the Mortgaged Property, (v) modify the zoning
applicable to the Mortgaged Property, or (vi) otherwise adversely affect the
Mortgaged Property. Mortgagor shall initiate or appear in any legal action or
other appropriate proceedings when necessary to protect the Mortgaged Property
from damage. Mortgagor shall, upon written request of Lender, represent and
defend the interests of Lender in any proceedings described in this Section
1.21 or, at Lender’s election, pay the fees and expenses of any counsel
retained by Lender to represent the interest of Lender in any such proceedings,
in which event such fees and expenses shall be added to Mortgagor’s Liabilities
and shall bear interest at the Default Rate. 

                    1.22.     Environmental
Matters.

	
  

 	
  

 	
  

 
	
  

 	
 (a)        Mortgagor represents and warrants that Mortgagor has not
 generated, used, stored, treated, transported, manufactured, handled,
 produced or disposed of any Hazardous Materials (as defined in the Loan
 Agreement), on or off the Mortgaged Property in any manner which at any time
 violates any Environmental Law (as defined in the Loan Agreement) or any
 license, permit, certificate, approval or similar authorization thereunder
 and the operations of the Mortgagor comply in all material respects with all
 Environmental Laws and all licenses, permits, certificates, approvals and
 similar authorizations thereunder; (ii) there has been no investigation,
 proceeding, complaint, order, directive, claim, citation or notice by any
 governmental authority or any other Person, nor is any pending or to the best
 of the Mortgagor’s knowledge threatened, and Mortgagor shall immediately
 notify

 Lender upon becoming aware of any such investigation, proceeding,
 complaint, order, directive, claim, citation or notice and take prompt and
 appropriate actions to respond thereto, with respect to any non-compliance
 with or violation of the requirements of any Environmental Law by Mortgagor
 or the release, spill or discharge, threatened or actual, of any Hazardous
 Materials or the generation, use, storage, treatment, transportation,
 manufacture, handling, production or disposal of any Hazardous Materials or
 any other environmental, health or safety matter, which affects Mortgagor or
 its business, operations or assets or any properties at which Mortgagor has
 transported, stored or disposed of any Hazardous Materials; (iii) Mortgagor
 has no material liability (contingent or otherwise) in connection with a
 release, spill or discharge, threatened or actual, of any Hazardous Materials
 or the generation, use, storage, treatment, transportation, manufacture,
 handling, production or disposal of any Hazardous Materials; and (iv) without
 limiting the generality of the foregoing, Mortgagor shall, following the
 determination by Lender that there is non-compliance, or any condition which
 requires any action by or on behalf of Mortgagor in order to avoid any
 non-compliance, with any Environmental Law, at Mortgagor’s expense, cause an
 independent environmental engineer acceptable to Lender to conduct such tests
 of the relevant site(s) as are appropriate and prepare and deliver a report
 setting forth the result of such tests, a proposed plan for remediation and
 an estimate of the costs thereof; and 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)     Mortgagor agrees to defend (with counsel satisfactory to Lender),
 protect, indemnify and hold harmless Lender, each affiliate or subsidiary of
 Lender, and each of their respective officers, directors, employees,
 attorneys and agents (each an “Indemnified Party”)
 from and against any and all liabilities, obligations, losses, damages,
 penalties, actions, judgments, suits, claims, costs, expenses and
 disbursements of any kind or nature (including, without limitation, the
 disbursements and the reasonable fees of counsel for each Indemnified Party in
 connection with any investigative, administrative or judicial proceeding,
 whether or not the Indemnified Party shall be designated a party thereto),
 which may be imposed on, incurred by, or asserted against, any Indemnified
 Party (whether direct, indirect or consequential and whether based on any
 federal, state or local laws or regulations, including, without limitation,
 securities laws and regulations, Environmental Laws and commercial laws and
 regulations, under common law or in equity, or based on contract or
 otherwise) in any manner relating to or arising out of this Mortgage or any
 other Loan

 Instrument, or any act, event or transaction related or attendant
 thereto, the making or issuance and the management of the Loans or the use or
 intended use of the proceeds of the Loans; provided, however, that Mortgagor
 shall not have any obligation hereunder to any Indemnified Party with respect
 to matters caused by or resulting from the willful misconduct or gross
 negligence of such Indemnified Party, further provided, that with respect to
 matters asserted by the Mortgagor, Mortgagor shall not have any obligations
 hereunder to any Indemnified Party in the event the Mortgagor has obtained a
 final nonappealable judgment in its favor. To the extent that the undertaking
 to indemnify set forth in the preceding sentence may be unenforceable because
 it is violative of any law or public policy, Mortgagor shall satisfy such
 undertaking to the maximum extent permitted by applicable law. Any liability,
 obligation, loss, damage, penalty, cost or expense covered by this indemnity
 shall be paid to each Indemnified Party on demand, and, failing prompt
 payment, shall, together with interest thereon at the highest rate then
 applicable to Loans hereunder from the date incurred by each Indemnified
 Party until paid by Mortgagor, be added to the Mortgagor’s Liabilities and be
 secured by the Mortgaged Property. The provisions of this paragraph shall
 survive the satisfaction and payment of the other Mortgagor’s Liabilities and
 the release of this Mortgage.

ARTICLE THREE

REMEDIES

                    3.1.     Acceleration
of Maturity. If an Event of Default shall have
occurred, Lender may declare Mortgagor’s Liabilities to be immediately due and
payable, and upon such declaration Mortgagor’s Liabilities shall immediately
become and be due and payable without further demand or notice. The foregoing
shall not be in limitation of any provision contained in any other Loan
Instrument, including without limitation any such provision pursuant to which
Mortgagor’s Liabilities become immediately due and payable without action or
election by Lender. 

                    3.2.     Lender’s
Power of Enforcement. If an Event of Default shall
have occurred, Lender may, either with or without entry or taking possession as
provided in this Mortgage or otherwise, and without regard to whether or not
Mortgagor’s Liabilities shall have been accelerated, and without prejudice to
the right of Lender thereafter to bring an action of foreclosure or any other
action for any default existing at the time such earlier action was commenced
or arising thereafter, proceed by any appropriate action or proceeding: (a) to
enforce satisfaction of the Guaranty and/or any other of Mortgagor’s
Liabilities or the performance of any term hereof or any of the other Loan
Instruments; (b) to foreclose this Mortgage and to have sold, as an entirety or
in separate lots or parcels, the Mortgaged Property; and (c) to pursue any
other remedy available to it. Lender may take action either by such proceedings
or by the exercise of its powers with respect to entry or taking possession, or
both, as Lender may determine. Without limitation of the foregoing, if an Event
of Default shall have occurred, as an alternative to the right of foreclosure
for the full indebtedness evidenced by the Guaranty and the interest accrued
thereon and any other Mortgagor’s Liabilities, after acceleration thereof,
Lender shall have the right to institute partial foreclosure proceedings with
respect to the portion of Mortgagor’s Liabilities so in default, as if under a
full foreclosure, and without declaring all of Mortgagor’s Liabilities to be
immediately due and payable (such proceedings being referred to herein as “partial foreclosure”),
and provided that, if Lender has not elected to accelerate all of Mortgagor’s
Liabilities and a foreclosure sale is made because of default in payment of
only a part of Mortgagor’s Liabilities, such sale may be made subject to the
continuing lien of this Mortgage for the unmatured part of Mortgagor’s
Liabilities. Any sale pursuant to a partial foreclosure, if so made, shall not
in any manner affect the unmatured portion of Mortgagor’s Liabilities, but as
to such unmatured portion, this Mortgage and the lien thereof shall remain in
full force and effect just as though no 

59

foreclosure sale had been made. Notwithstanding the filing of any
partial foreclosure or entry of a decree of sale therein, Lender may elect, at
any time prior to a foreclosure sale pursuant to such decree, to discontinue
such partial foreclosure and to accelerate Mortgagor’s Liabilities by reason of
any Event of Default upon which such partial foreclosure was predicated or by
reason of any other defaults, and proceed with full foreclosure proceedings.
Lender may proceed with one or more partial foreclosures without exhausting its
right to proceed with a full or partial foreclosure sale for any unmatured
portion of Mortgagor’s Liabilities, it being the purpose to permit, from time
to time a partial foreclosure sale for any matured portion of Mortgagor’s
Liabilities without exhausting the power to foreclose and to sell the Mortgaged
Property pursuant to any partial foreclosure in respect of any other portion of
Mortgagor’s Liabilities, whether matured at the time or subsequently maturing,
and without exhausting at any time the right of acceleration and the right to
proceed with a full foreclosure. 

                    3.3.      Lender’s
Right to Enter and Take Possession, Operate and Apply Income.

	
  

 	
  

 	
  

 
	
  

 	
 (a)        If an Event of Default shall have
 occurred, (i) Mortgagor, upon demand of Lender, shall forthwith surrender to
 Lender the actual possession of the Mortgaged Property, and to the extent
 permitted by law, Lender itself, or by such officers or agents as it may
 appoint, is hereby expressly authorized to enter and take possession of all
 or any portion of the Mortgaged Property and may exclude Mortgagor and the
 agents and employees of Mortgagor wholly therefrom and shall have joint
 access with Mortgagor to the books, papers and accounts of Mortgagor; and
 (ii) notwithstanding the provisions of any lease or other agreement to the
 contrary, Mortgagor shall pay monthly in advance to Lender, on Lender’s entry
 into possession, or to any receiver appointed to collect the rents, income
 and other benefits of the Mortgaged Property, the fair and reasonable rental
 value for the use and occupation of such part of the Mortgaged Property as
 may be in possession of Mortgagor, or any entity affiliated with or
 controlled by Mortgagor, and upon default in any such payment Mortgagor shall
 vacate and surrender possession of such part of the Mortgaged Property to
 Lender or to such receiver, and in default thereof Mortgagor may be evicted
 by summary proceedings or otherwise. 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)        If Mortgagor shall for any reason
 fail to surrender or deliver the Mortgaged Property or any part thereof after
 Lender’s demand, Lender may obtain a judgment or decree conferring on Lender
 the right to immediate possession or requiring Mortgagor to deliver immediate
 possession of all or part of the Mortgaged Property to Lender, to the entry
 of which judgment or decree Mortgagor hereby specifically consents. Mortgagor
 shall pay to Lender, upon

 demand, all costs and expenses of obtaining such judgment or decree
 and reasonable compensation to Lender, its attorneys and agents, and all such
 costs, expenses and compensation shall, until paid, be secured by the lien of
 this Mortgage. 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (c)     Upon every such entering upon or
 taking of possession, Lender, to the extent permitted by law, may hold,
 store, use, operate, manage and control the Mortgaged Property and conduct
 the business thereof, and, from time to time: 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (i)     perform such construction, make all
 necessary and proper maintenance, repairs, renewals, replacements, additions
 and improvements thereto and thereon, and purchase or otherwise acquire
 additional fixtures and personal property;

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (ii)     insure or keep the Mortgaged
 Property insured;

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (ii)     manage and operate the Mortgaged
 Property and exercise all the rights and powers of Mortgagor, on its behalf
 or otherwise, with respect to the same;

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (iv)     enter into agreements with others
 to exercise the powers herein granted Lender, all as Lender from time to time
 may determine; and Lender may collect and receive all the rents, income and
 other benefits of the Mortgaged Property, including those past due as well as
 those accruing thereafter; and shall apply the monies so received by Lender,
 in such order and manner as Lender may determine, to (1) the payment of
 amounts due under the Guaranty or pursuant to this Mortgage or to any other
 Mortgagor’s Liabilities, (2) deposits for taxes and assessments, (3) the
 payment or creation of reserves for payment of insurance, taxes, assessments
 and other proper charges or liens or encumbrances upon the Mortgaged Property
 or any part thereof, and (4) the compensation, expenses and disbursements of
 the agents, attorneys and other representatives of Lender; and 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (v)     exercise such remedies as are
 available to Lender under the Loan Instruments or at law or in equity. 

 	
  

 

Lender shall surrender possession of the Mortgaged Property to
Mortgagor only when all Mortgagor’s Liabilities shall have been paid in full
and all other defaults have been cured. However, the same right to take
possession shall exist if any subsequent Event of Default shall occur.

                    3.4.     Leases.
Lender is authorized to foreclose this Mortgage subject to the rights, if any,
of any or all tenants of the Mortgaged Property, even if the rights of any such
tenants are or would be subordinate to the lien of this Mortgage. Lender may
elect to foreclose the rights of some subordinate tenants while foreclosing
subject to the rights of other subordinate tenants. 

                    3.5.     Purchase
by Lender. Upon any foreclosure sale, Lender may bid
for and purchase all or any portion of the Mortgaged Property and, upon
compliance with the terms of the sale, may hold, retain and possess and dispose
of such property in its own absolute right without further accountability. 

                    3.6.     Application
of Foreclosure Sale Proceeds. The proceeds of any
foreclosure sale of the Mortgaged Property or any part thereof received by
Lender shall be applied by Lender to the indebtedness secured hereby in such
order and manner as Lender may elect. 

                    3.7.     Application
of Indebtedness Toward Purchase Price. Upon any foreclosure
sale, Lender may apply any or all of the indebtedness and other sums due to
Lender under the Guaranty, this Mortgage or any other Loan Instrument to the
price paid by Lender at the foreclosure sale. 

                    3.8.     Waiver
of Appraisement, Valuation, Stay, Extension and Redemption Laws.
Mortgagor hereby waives any and all rights of redemption. Mortgagor further
agrees, to the full extent permitted by law, that in case of an Event of
Default, neither Mortgagor nor anyone claiming through or under it will set up,
claim or seek to take advantage of any reinstatement, appraisement, valuation,
stay or extension laws now or hereafter in force, or take any other action
which would prevent or hinder the enforcement or foreclosure of this Mortgage
or the absolute sale of the Mortgaged Property or the final and absolute
putting into possession thereof, immediately after such sale, of the purchaser
thereat. Mortgagor, for itself and all who may at any time claim through or
under it, hereby waives, to the full extent that it may lawfully so do, the
benefit of all such laws, and any and all right to have the assets comprising
the Mortgaged Property marshalled upon any foreclosure of the lien hereof and
agrees that Lender or any court having jurisdiction to foreclose such lien may
sell the Mortgaged Property in part or as an entirety. 

                    3.9.     Receiver
- Lender in Possession. If an Event of Default shall
have occurred, Lender, to the extent permitted by law and without regard to the
value of the Mortgaged Property or the adequacy of the security for the
indebtedness and other sums secured hereby, shall be entitled as a matter of
right and without any additional showing or proof, at Lender’s election, to
either the appointment by the court of a receiver (without the necessity of
Lender posting a bond) to enter upon and take possession of the Mortgaged
Property and to collect all rents, income and other benefits thereof and apply
the same as the court may direct or to be placed by the court into possession
of the Mortgaged Property as mortgagee in possession with the same power herein
granted to a receiver

and with all other rights and privileges of a mortgagee in possession
under law. The right to enter and take possession of and to manage and operate
the Mortgaged Property, and to collect all rents, income and other benefits
thereof, whether by a receiver or otherwise, shall be cumulative to any other
right or remedy hereunder or afforded by law and may be exercised concurrently
therewith or independently thereof. Lender shall be liable to account only for
such rents, income and other benefits actually received by Lender, whether
received pursuant to this Section 3.9 or Section 3.3. Notwithstanding the
appointment of any receiver or other custodian, Lender shall be entitled as
pledgee to the possession and control of any cash, deposits or instruments at
the time held by, or payable or deliverable under the terms of this Mortgage to
Lender.

                    3.10.     Mortgagor
to Pay Mortgagor’s Liabilities in Event of Default; Application of Monies by
Lender.

	
  

 	
  

 	
  

 
	
  

 	
 (a)        Upon occurrence of an Event of
 Default, Lender shall be entitled to sue for and to recover judgment against
 Mortgagor for Mortgagor’s Liabilities due and unpaid together with costs and
 expenses, including, without limitation, the reasonable compensation,
 expenses and disbursements of Lender’s agents, attorneys and other
 representatives, either before, after or during the pendency of any
 proceedings for the enforcement of this Mortgage; and the right of Lender to
 recover such judgment shall not be affected by any taking of possession or
 foreclosure sale hereunder, or by the exercise of any other right, power or
 remedy for the enforcement of the terms of this Mortgage, or the foreclosure
 of the lien hereof. 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)        In case of a foreclosure sale of all
 or any part of the Mortgaged Property and of the application of the proceeds
 of sale to the payment of Mortgagor’s Liabilities, Lender shall be entitled
 to enforce all other rights and remedies under the Loan Instruments. 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (c)        Mortgagor hereby agrees, to the
 extent permitted by law, that no recovery of any judgment by Lender under any
 of the Loan Instruments, and no attachment or levy of execution upon any of
 the Mortgaged Property or any other property of Mortgagor, shall (except as
 otherwise provided by law) in any way affect the lien of this Mortgage upon
 the Mortgaged Property or any part thereof or any lien, rights, powers or
 remedies of Lender hereunder, but such lien, rights, powers and remedies

                    4.3.     Headings.
The headings of the articles, sections, paragraphs and subdivisions of this
Mortgage are for convenience only, are not to be considered a part hereof, and
shall not limit, expand or otherwise affect any of the terms hereof. 

                    4.4.     Invalid
Provisions. In the event that any of the covenants,
agreements, terms or provisions contained in the Guaranty, the Notes, this
Mortgage or in any other Loan Instrument shall be invalid, illegal or

shall be in no way affected, prejudiced or disturbed thereby. 

                    4.5.     Changes.
Neither this Mortgage nor any term hereof may be released, changed, waived,
discharged or terminated orally, or by any action or inaction, but only by an
instrument in writing signed by the party against which enforcement of the
release, change, waiver, discharge or termination is sought. To the extent
permitted by law, any agreement hereafter made by Mortgagor and Lender relating
to this Mortgage shall be superior to the rights of the holder of any
intervening lien or encumbrance. Any holder of a lien or encumbrance junior to
the lien of this Mortgage shall take its lien subject to the right of Lender to
amend, modify or supplement this Mortgage, the Guaranty or any of the other
Loan Instruments, to extend the maturity of Mortgagor’s Liabilities or any
portion thereof, to vary the rate of interest chargeable under the Notes and to
increase the amount of the indebtedness secured hereby, in each and every case
without obtaining the 

65

LaSalle Bank
National Association

Page 66 

consent of the holder of such junior lien and without the lien of this
Mortgage losing its priority over the rights of any such junior lien. 

                    4.6.     Governing
Law. This Mortgage shall be construed, interpreted,
enforced and governed by and in accordance with the laws of the State of
Illinois except
that the internal laws of the State where the Mortgaged Property is located
shall govern with respect to the validity, creation, perfection, priority and
enforcement of the liens and security interests created hereby. 

                    4.7.     Required
Notices. Mortgagor shall notify Lender promptly of the
occurrence of any of the following: (i) receipt of notice from any governmental
authority relating to the violation of any rule, regulation, law or ordinance,
the enforcement of which would materially and adversely affect the Mortgaged Property;
(ii) material default by any tenant in the performance of its obligations under
any lease of all or any portion of the Mortgaged Property or receipt of any
notice from any such tenant claiming that a default by landlord in the
performance of its obligations under any such lease has occurred; or (iii)
commencement of any judicial or administrative proceedings by or against or
otherwise adversely affecting Mortgagor or the Mortgaged Property. 

                    4.8.     Future
Advances. This Mortgage is given to secure a guaranty
of not only existing indebtedness, but also future advances (whether such
advances are obligatory or are to be made at the option of Lender, or
otherwise) made by Lender under the Notes, to the same extent as if such future
advances were made on the date of the execution of this Mortgage. The total
amount of principal indebtedness that may be so secured may decrease or
increase from time to time, but all principal indebtedness secured hereby
shall, in no event, exceed $ 30,000,000. 

                    4.9.     Release.
Upon full payment and satisfaction of Mortgagor’s Liabilities, Lender shall
issue to Mortgagor an appropriate release deed in recordable form. 

                    4.10.     Attorneys’
Fees. Whenever reference is made herein to the payment
or reimbursement of attorneys’ fees, such fees shall be deemed to include
compensation to staff counsel, if any, of Lender in addition to the fees of any
other attorneys engaged by Lender. All attorneys’ fees incurred by Lender in
connection with the foreclosure of this Mortgage shall be recoverable in
foreclosure. 

                    4.11.     Compliance
with Mortgage Foreclosure Law. In the event that any
provision in this Mortgage shall be inconsistent with any applicable statutory
provision governing the creation, perfection or enforcement of mortgages, such
provisions shall take precedence over the provisions of this Mortgage, but
shall not invalidate or render unenforceable any other provision of this
Mortgage that can be construed in a manner consistent with such provisions. If
any provision of this Mortgage shall grant to Lender any rights or remedies
upon default of Mortgagor which are more limited than the rights that would
otherwise be vested in Lender under applicable law in the absence of said 

66

LaSalle Bank
National Association

provision, Lender shall be vested with such rights applicable law to
the full extent permitted by law. 

                    4.12.     WAIVER
OF TRIAL BY JURY. TO INDUCE LENDER TO MAKE THE LOAN,
MORTGAGOR HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY AND IRREVOCABLY WAIVES
ANY AND ALL RIGHTS WHICH MORTGAGOR MAY HAVE TO TRIAL BY JURY IN RESPECT OF ANY
LEGAL PROCEEDINGS IN WHICH MORTGAGOR AND LENDER ARE ADVERSE PARTIES, IN

VOLUNTARILY, INTENTIONALLY AND IRREVOCABLY WAIVES PERSONAL SERVICE OF ANY AND
ALL PROCESS, AND CONSENTS THAT, AT LENDER’S OPTION, ALL SUCH SERVICE OF PROCESS
MAY BE MADE BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED, DIRECTED TO MORTGAGOR
AT THE ADDRESS FOR MORTGAGOR INDICATED IN SECTION 4.2 ABOVE.

 with respect to the exercise of the Purchase Option, and to perform all acts,
 and exercise all rights and remedies, which Assignor could perform and
 exercise thereunder, and hereby irrevocably appoints Assignee as Assignor’s

                 (b)     Assignor
 has not received notice of, and is not otherwise aware of, any default under

                 (c)     Except

                 (d)     The

 shall not in any way satisfy or discharge this Assignment, but this
 Assignment shall remain in full force and effect until the date upon which
 the Liabilities are paid and satisfied in full. This Assignment shall be
 binding upon Assignor and its successors and assigns and shall inure to the benefit
 of Assignee and its successors and assigns.

 
	
  

 	
  

 
	
  

 	
                     8.     Severability.

from time to time, this “ Guaranty ”), made by each of the undersigned
Subsidiary Guarantors (each, a “ Subsidiary Guarantor ” and, together
with any other entity that becomes a Subsidiary Guarantor hereunder pursuant to
Section 21 hereof, the “ Subsidiary Guarantors ” ). Except as
otherwise defined herein, capitalized terms used herein and defined in the
Credit Agreement (as defined below) shall be used herein as therein defined. 

WITNESSETH:

          WHEREAS,
Quixote Corporation (the “Borrower”), the lenders from time to time
party thereto (the “ Lenders ”), The Northern Trust Corporation, as
Administrative Agent (the “Agent”) and Lender, and LaSalle Bank National
Association, as Co-Agent, have entered into a Credit Agreement, dated as of May
16, 2003 (as amended, modified, restated and/or supplemented from time to time,
the “ Credit Agreement ”), providing for the making of Loans to, and the
issuance of, and participation in, Letters of Credit for the account of, the
Borrower, all as contemplated therein (the Lenders, each Issuing Lender, the
Agent, the Co-Agent, each other agent, herein collectively called the “
Lenders ”); 

                    WHEREAS,
each Subsidiary Guarantor is a direct or indirect Subsidiary of the Borrower; 

                    WHEREAS,
it is a condition precedent to the making of Loans to, and the issuance of, and
participation in, Letters of Credit for the account of the Borrower under the
Credit Agreement that each Subsidiary Guarantor shall have executed and
delivered this Guaranty; and 

                    WHEREAS,
each Subsidiary Guarantor will obtain benefits from the incurrence of Loans by,
and the issuance of, and participation in, Letters of Credit for the account
of, the Borrower under the Credit Agreement and, accordingly, desires to
execute this Guaranty in order to satisfy the condition described in the
preceding paragraph and to induce the Lenders to make Loans to the Borrower and
issue, and/or participate in, Letters of Credit for the account of the
Borrower; 

                    NOW,
THEREFORE, in consideration of the foregoing and other benefits accruing to
each Subsidiary Guarantor, the receipt and sufficiency of which are hereby
acknowledged, each Subsidiary Guarantor hereby makes the following
representations and warranties to the Agent and Lenders and hereby covenants
and agrees with the Agent and each Lender as follows:

                              1.          Each
Subsidiary Guarantor, jointly and severally, irrevocably, absolutely and
unconditionally guarantees: (i) to the Agent, for the benefit of the Lenders,
the full and

prompt payment
when due (whether at the stated maturity, by acceleration or otherwise) of (x)
the principal of, premium, if any, and interest on the Notes issued by, and the
Loans made to, the Borrower under the Credit Agreement, and all reimbursement
obligations and unpaid drawings with respect to Letters of Credit and (y) all
other obligations (including obligations which, but for the automatic stay
under Section 362(a) of the Bankruptcy Code or other applicable bankruptcy or
insolvency laws, would become due), liabilities and indebtedness owing by the
Borrower to the Lenders under the Credit Agreement and each other Loan Document
to which the Borrower is a party (including, without limitation, indemnities,
fees and interest thereon (including, in each case, any interest accruing after
the commencement of any bankruptcy, insolvency, receivership or similar
proceeding at the rate provided for in the Credit Agreement, whether or not
such interest is an allowed claim in any such proceeding), whether now existing
or hereafter incurred under, arising out of or in connection with the Credit
Agreement and any such other Credit Document and the due performance and
compliance by the Borrower with all of the terms, conditions and agreements
contained in all such Loan Documents (all such principal, premium, interest,
liabilities, indebtedness and obligations being herein collectively called the
“ Guaranteed Obligations ”). Each Subsidiary Guarantor understands,
agrees and confirms that the Agent, for the benefit of the Lenders, may enforce
this Guaranty up to the full amount of the Guaranteed Obligations against such
Subsidiary Guarantor without proceeding against any other Subsidiary Guarantor,
the Borrower, or under any other guaranty covering all or a portion of the
Guaranteed Obligations. This Guaranty shall constitute a guaranty of payment
and not of collection. 

                              2.          The
liability of each Subsidiary Guarantor hereunder is primary, absolute, joint
and several, and unconditional and is exclusive and independent of any security
for or other guaranty of the indebtedness of the Borrower whether executed by
such Subsidiary Guarantor, any other Subsidiary Guarantor or by any other
party, and the liability of each Subsidiary Guarantor hereunder shall not be
affected or impaired by any circumstance or occurrence whatsoever, including,
without limitation: (i) any direction as to application of payment by Borrower
or by any other party other than the Agent, (ii) any other continuing or other
guaranty, undertaking or maximum liability of a Subsidiary Guarantor or of any
other party as to the Guaranteed Obligations, (iii) any payment on or in
reduction of any such other guaranty or undertaking, (iv) any dissolution,
termination or increase, decrease or change in personnel by Borrower, (v) any
payment made to any Lender on the indebtedness which any Lender repays to the
Borrower pursuant to court order in any bankruptcy, reorganization,
arrangement, moratorium or other debtor relief proceeding, and each Subsidiary
Guarantor waives any right to the deferral or modification of its obligations
hereunder by reason of any such proceeding, (vi) any action or inaction by the
Agent or any Lender as contemplated in Section 5 hereof, (vii) any invalidity,
irregularity or unenforceability of all or any part of the Guaranteed
Obligations or of any security therefor or (viii) to the extent permitted by
applicable law, any other circumstances which might otherwise constitute a
defense available to, or a discharge of, the Borrower in respect of the
Guaranteed Obligations or of any Subsidiary Guarantor in respect of this
Guaranty.

obligations of each Subsidiary Guarantor hereunder are independent of the
obligations of any other Subsidiary Guarantor, any other Subsidiary Guarantor,
the Borrower and a separate action or actions may be brought and prosecuted
against each Subsidiary Guarantor whether or not action is brought against any

Subsidiary Guarantor, the Borrower and whether or not any other Subsidiary
Guarantor, any other Subsidiary Guarantor, the Borrower be joined in any such
action or actions. Each Subsidiary Guarantor waives, to the fullest extent
permitted by law, the benefits of any statute of limitations affecting its
liability hereunder or the enforcement thereof. Any payment by the Borrower or
other circumstance which operates to toll any statute of limitations as to the
Borrower shall operate to toll the statute of limitations as to each Subsidiary
Guarantor to the fullest extent permitted by law. 

                              4.          Each
Subsidiary Guarantor hereby waives to the fullest extent permitted by
applicable law, notice of acceptance of this Guaranty and notice of any
liability to which it may apply, and waives promptness, diligence, presentment,
demand of payment, protest, notice of dishonor or nonpayment of any such
liabilities, suit or taking of other action by the Agent or any other Lender against,
and any other notice to, any party liable thereon (including such Subsidiary
Guarantor and the Borrower). 

                              5.          The
Agent, on behalf of the Lenders, or the Lenders may at any time and from time
to time without the consent of, or notice to, any Subsidiary Guarantor, without
incurring responsibility to such Subsidiary Guarantor, without impairing or
releasing the obligations of such Subsidiary Guarantor hereunder, upon or
without any terms or conditions and in whole or in part: 

	
  

 	
  

 
	
  

 	
                                  (i)          change
 the manner, place or terms of payment of, and/or change or extend the time of
 payment of, renew, increase, accelerate or alter, any of the Guaranteed
 Obligations (including any increase or decrease in the rate of interest
 thereon), any security therefor, or any liability incurred directly or
 indirectly in respect thereof, and the guaranty herein made shall apply to
 the Guaranteed Obligations as so changed, extended, renewed, increased or altered;
 

 
	
  

 	
  

 
	
  

 	
                                  (ii)         take
 and hold security for the payment of the Guaranteed Obligations and/or sell,
 exchange, release, surrender, impair, realize upon or otherwise deal with in
 any manner and in any order any property by whomsoever at any time pledged or
 mortgaged to secure, or howsoever securing, the Guaranteed Obligations or any
 liabilities (including any of those hereunder) incurred directly or
 indirectly in respect thereof or hereof, and/or any offset thereagainst; 

 
	
  

 	
  

 
	
  

 	
                                 
 (iii)        exercise or refrain from
 exercising any rights against the Borrower or any Subsidiary thereof or
 otherwise act or refrain from acting; 

 
	
  

 	
  

 
	
  

 	
                                  (iv)        settle
 or compromise any of the Guaranteed Obligations, any security therefor or any
 liability (including any of those hereunder) incurred directly or indirectly
 in respect thereof or hereof, and may subordinate the payment of

 all or any
 part thereof to the payment of any liability (whether due or not) of the
 Borrower to creditors of Borrower other than the Lenders;

                                   (v)        apply
 any sums by whomsoever paid or howsoever realized to any liability or
 liabilities of the Borrower to the Lenders regardless of what liabilities of
 the Borrower remain unpaid; 

 
	
  

 	
  

 
	
  

 	
                                   (vi)       release
 or substitute any one or more endorsers, other Subsidiary Guarantor, the
 Borrower or other obligors;

 
	
  

 	
  

 
	
  

 	
                                   (vii)      consent
 to or waive any breach of, or any act, omission or default under, any of the
 Loan Documents or any of the instruments or agreements referred to therein,
 or otherwise amend, modify or supplement any of the Loan Documents or any of
 such other instruments or agreements;

 
	
  

 	
  

 
	
  

 	
                                   (viii)     act
 or fail to act in any manner referred to in this Guaranty which may deprive
 such Subsidiary Guarantor of its right to subrogation against the Borrower to
 recover full indemnity for any payments made pursuant to this Guaranty;
 and/or

 
	
  

 	
  

 
	
  

 	
                                   (ix)       take
 any other action which could, under otherwise applicable principles of common
 law, give rise to a legal or equitable discharge of any Subsidiary Guarantor
 from its liabilities under this Guaranty.

 

                               6.          No
invalidity, irregularity or unenforceability of all or any part of the
Guaranteed Obligations or of any security therefor shall affect, impair or be a
defense to this Guaranty, and this Guaranty shall be primary, absolute and
unconditional notwithstanding the occurrence of any event or the existence of
any other circumstances which might constitute a legal or equitable discharge
of a surety or Subsidiary Guarantor except payment in full of the Guaranteed
Obligations. 

                              7.          This
Guaranty is a continuing one and all liabilities to which it applies or may
apply under the terms hereof shall be conclusively presumed to have been
created in reliance hereon. No failure or delay on the part of the Agent, on
behalf of the Lenders, or any Lender in exercising any right, power or
privilege hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies herein expressly specified are cumulative
and not exclusive of any rights or remedies which any Lender would otherwise
have. No notice to or demand on any Subsidiary Guarantor in any case shall
entitle such Subsidiary Guarantor to any other further notice or demand in
similar or other circumstances or constitute a waiver of the rights of any
Lender to any other or further action in any circumstances without notice or
demand. It is not necessary for the Agent or any Lender to inquire into the
capacity or powers of the Borrower or the officers, directors, partners or
agents acting or purporting to act on its or their behalf, and any 

97

indebtedness
made or created in reliance upon the professed exercise of such powers shall be
guaranteed hereunder. 

                              8.          (a)
Each Subsidiary Guarantor waives any right (except as shall be required by
applicable law and cannot be waived) to require the Agent or any Lender to: (i)
proceed against the Borrower, of the Guaranteed Obligations or any other party;
(ii) proceed 

98

 against or
 exhaust any security held from the Borrower of the Guaranteed Obligations or
 any other party; or (iii) pursue any other remedy in the Agent’s or any
 Lender’s power whatsoever. Each Subsidiary Guarantor waives any defense based
 on or arising out of any defense of the Borrower of the Guaranteed
 Obligations or any other party other than payment in full of the Guaranteed
 Obligations, including, without limitation, any defense based on or arising
 out of the disability of the Borrower of the Guaranteed Obligations or any
 other party, or the unenforceability of the Guaranteed Obligations or any
 part thereof from any cause, or the cessation from any cause of the liability
 of the Borrower other than payment in full of the Guaranteed Obligations in
 cash. 

 
	
  

 	
  

 
	
  

 	
                                 (b)          Each
 Subsidiary Guarantor assumes all responsibility for being and keeping itself
 informed of the Borrower’s financial condition and assets, and of all other
 circumstances bearing upon the risk of nonpayment of the Guaranteed
 Obligations and the nature, scope and extent of the risks which such
 Subsidiary Guarantor assumes and incurs hereunder, and agrees that the Agent
 or any Lender shall have no duty to advise any Subsidiary Guarantor of
 information known to them regarding such circumstances or risks. 

 
	
  

 	
  

 
	
  

 	
                                 (c)          Until
 such time as the Guaranteed Obligations have been paid in full in cash, each
 Subsidiary Guarantor hereby waives all contractual, statutory, common law or
 other rights of reimbursement, contribution or indemnity from the Borrower,
 which it may at any time otherwise have as a result of this Guaranty. 

 
	
  

 	
  

 
	
                               9.          In
 order to induce the Lenders to make Loans to, and issue Letters of Credit for
 the account of, the Borrower pursuant to the Credit Agreement, Subsidiary
 Guarantor represents, warrants and covenants that: 

 
	
  

 	
  

 
	
  

 	
                                 (a)          such
 Subsidiary Guarantor (i) is a duly organized and validly existing
 corporation, partnership or limited liability company, as the case may be, in
 good standing under the laws of the jurisdiction of its organization, (ii)
 has the power and authority to own its property and assets and to transact
 the business in which it is engaged and presently proposes to engage and
 (iii) is duly qualified and is authorized to do business and is in good
 standing in all jurisdictions where it is required to be so qualified except
 for failures to be so qualified which, individually or in the aggregate,
 would not reasonably be expected to have a Material Adverse Effect; 

 
	
  

 	
  

 
	
  

 	
                                 (b)          such
 Subsidiary Guarantor has the power and authority to execute, deliver and
 perform this Guaranty and each other Loan Document (such term, for purposes
 of this Guaranty, to mean each Loan Document (as defined in the Credit
 Agreement) to which it is a party) and has taken all necessary action to
 authorize the execution, delivery and performance by it of each such Loan
 Document;

                                 (c)          such
 Subsidiary Guarantor has duly executed and delivered this Guaranty and each
 other Loan Document to which it is a party, and each such Loan Document
 constitutes the legal, valid and binding obligation of such Subsidiary
 Guarantor enforceable against such Subsidiary Guarantor in accordance with
 its terms,

 except to
 the extent that the enforceability hereof or thereof may be limited by
 applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
 moratorium or other similar laws generally affecting creditors’ rights and by
 equitable principles (regardless of whether enforcement is sought in equity
 or at law); 

 
	
  

 	
  

 
	
  

 	
                                 (d)          neither
 the execution, delivery or performance by such Subsidiary Guarantor of this
 Guaranty or any other Loan Document to which it is a party, nor compliance by
 it with the terms and provisions hereof and thereof nor the consummation of
 the transactions contemplated therein: (i) will contravene any material
 provision of any applicable law, statute, rule or regulation, or any
 applicable order, writ, injunction or decree of any court or governmental
 instrumentality applicable to the Subsidiary Guarantors, (ii) will conflict
 or be inconsistent with or result in any breach of, any of the terms,
 covenants, conditions or provisions of, or constitute a default under, or
 result in the creation or imposition of (or the obligation to create or
 impose) any Lien upon any of the material properties or assets of such
 Subsidiary Guarantor or any of its Subsidiaries pursuant to the terms of any
 indenture, mortgage, deed of trust, credit agreement or loan agreement or any
 other material agreement, contract or other instrument to which such
 Subsidiary Guarantor or any of its Subsidiaries is a party or by which it or
 any of its material properties or assets is bound or to which it may be
 subject except any conflict, inconsistency or breach which individually or in
 the aggregate could not reasonably be expected to have a Material Adverse
 Effect or (iii) will violate any provision of the certificate or articles of
 incorporation, by-laws, certificate of partnership, partnership agreement,
 certificate of formation or limited liability company agreement (or
 equivalent organizational documents), as the case may be, of such Subsidiary
 Guarantor or any of its Subsidiaries; 

 
	
  

 	
  

 
	
  

 	
                                 (e)          no
 order, consent, approval, license, authorization or validation of, or filing,
 recording or registration with (except as have been obtained or made prior to
 the date when required and which remain in full force and effect), or

 subdivision thereof, is required with respect to such Subsidiary Guarantor to
 authorize, or is required by such Subsidiary Guarantor in connection with,
 (i) the execution, delivery and performance of this Guaranty or any other
 Loan Document to which such Subsidiary Guarantor is a party, or (ii) the
 legality, validity, binding effect or enforceability of this Guaranty or any
 other Loan Document to which such Subsidiary Guarantor is a party; and 

 
	
  

 	
  

 
	
  

 	
                                 (f)          there
 are no actions, suits or proceedings pending or, to the knowledge of such
 Subsidiary Guarantor, threatened (i) with respect to this Guaranty or any
 other Loan Document to which such Subsidiary Guarantor is a party, or (ii)
 which is, or could reasonably be expected to have, a Material Adverse Effect.

                              10.          Each
Subsidiary Guarantor covenants and agrees that on and after the date hereof and
until the termination of the Credit Agreement, no Note or Letter of Credit
remains outstanding and all other Guaranteed Obligations have been paid in
full, such Subsidiary Guarantor shall use all reasonable efforts to take, or

to be taken or
not taken so that no violation of any provision, covenant or agreement
contained in Section VII of the Credit Agreement, and so that no Event of
Default, is caused by the actions of such Subsidiary Guarantor or any of its
Subsidiaries. 

                              11.          The
Subsidiary Guarantors hereby jointly and severally agree to pay all
out-of-pocket costs and expenses of the Agent and each Lender in connection
with the enforcement of this Guaranty and the protection of such Agent or any
Lender’s rights hereunder, and in connection with any amendment, waiver or
consent relating hereto (including, without limitation, the reasonable fees and
disbursements of counsel employed by the Agents or any of the Lenders). 

                              12.          This
Guaranty shall be binding upon each Subsidiary Guarantor and its successors and
assigns and shall inure to the benefit of the Agent and each Lender and their
successors and assigns. 

                              13.          Neither
this Guaranty nor any provision hereof may be changed, waived, discharged or
terminated in any manner whatsoever unless in writing duly signed by the Agent
(with the consent of the Required Lenders (or, to the extent required by
Section 9.3 of the Credit Agreement, all of the Lenders) at all times prior to
the time at which all Guaranteed Obligations have been paid in full, and each
Subsidiary Guarantor directly affected thereby (it being understood that the
addition or release of any Subsidiary Guarantor hereunder shall not constitute
a change, waiver, discharge or termination affecting any Subsidiary Guarantor
other than the Subsidiary Guarantors so added or released). 

                              14.          Each
Subsidiary Guarantor acknowledges that an executed (or conformed) copy of each

anything else to the contrary in this Guaranty, Agent, on behalf of the

Litigation

	
  

 	
  

 	
  

 	
  

 
	
 A.

 	
 Bedlinger v.
 The Mills Corporation, Gaylor Entertainment and Safe-Hit Corporation, State
 of Tennessee Circuit Court of Davidson County, No. 02C2832.

 
	
  

 	
  

 	
  

 
	
  

 	
  

 	
 In October
 2002, EAS was served in this matter that alleges that the plaintiff was
 injured when she tripped over a surface mount twist-lock and post in a
 parking lot. Plaintiff seeks judgment for $1,000,000 in damages. The case has
 been tendered to the Company’s insurance carrier. Discovery to date indicates
 that plaintiff is a 77 year-old woman who broke her hip and wrist after
 tripping over a Safe-Hit post.

 
	
  

 	
  

 	
  

 
	
 B.

 	
 Dunn v.
 Quixote, Energy Absorption Systems, Inc., Safe-Hit, Inc., Department of
 Transportation et al., Circuit Court of Hawaii, No. 04-1-1330-07 SSM

 
	
  

 	
  

 
	
  

 	
  

 	
 In March
 2005 and late December 2004 the Company and EAS were served in this matter
 that alleges a bicyclist hit a Safe-Hit surface mount post and suffered head
 injuries when his helmet broke. The case has been tendered to the Company’s
 insurance carrier. The amount of damages is not alleged and discovery has not
 begun so a risk assessment cannot be made at this time.

MORTGAGE AND SECURITY AGREEMENT

          THIS MORTGAGE AND SECURITY AGREEMENT (“Mortgage”), made as of April 20,
2005, is made and executed by Spin-Cast Plastics, Inc., an Indiana corporation,
having its principal offices at 3300 North Kenmore Street, South Bend, Indiana
46628 (“Mortgagor”),
in favor of LASALLE BANK NATIONAL ASSOCIATION, a national banking association
having an office at 135 South LaSalle Street, Chicago, Illinois 60603 (“Lender”).

RECITALS

                    I.     Lender
has agreed to make loans to Quixote Corporation, a Delaware corporation (“Borrower”)
and extend other financial accommodations to Borrower in an aggregate principal
amount of $30,000,000 (collectively, the “Loans”). The Loans consist of one or more
revolving loans (the “Revolving Loan”), the outstanding principal
balance of which may increase or decrease from time to time, but at no time
shall the outstanding principal balance of such Revolving Loan exceed $30,000,000.
Certain repayment obligations of Borrower with respect to the Revolving Loan
are evidenced by a certain Revolving Note, in the principal amount of
$30,000,000 (said note, together with all allonges, amendments, supplements,
modifications and replacements thereof, being referred to in this Mortgage as
the “Revolving
Note”). The Revolving Note is sometimes referred to herein as the “Note.”
The terms of the Loans are governed by a certain Amended and Restated Credit
and Security Agreement, of even date herewith (amending and restating the
terms of the Credit Agreement dated, as of May 16, 2003, as amended)
by and between Borrower and Lender (said Credit Agreement, together with all
amendments, supplements, modifications and replacements thereof, being referred
to in this Mortgage as the “Loan Agreement”). The terms and provisions
of the Note and the Loan Agreement are hereby incorporated by reference in this
Mortgage. Capitalized terms not otherwise defined in this Mortgage shall have
the meaning ascribed to them in the Loan Agreement. As an inducement to Lender
to make the Loan, Mortgagor has executed and delivered to Lender the Loan

152

Page 153

Agreement, as a Subsidiary Guarantor thereunder, to evidence its
becoming a Subsidiary Guarantor, as defined in the Loan Agreement, under that
certain Subsidiary Guaranty (the “Guaranty”) of even date herewith, pursuant
to which Mortgagor has agreed to guaranty all of the indebtedness and
obligations of Borrower owed to Lender, including without limitation the
obligations of Borrower with respect to the Loan.

                    II.     This
Mortgage is given to secure a guaranty of one or more revolving loans and
secures not only present indebtedness but also future advances, whether such
future advances are obligatory or are to be made at the option of Lender, or
otherwise as are to be made within five (5) years of the date hereof. The amount
of indebtedness secured hereby may increase or decrease from time to time;
however the principal amount of such indebtedness shall not at one time exceed
the amount of $30,000,000 plus interest thereon, and other costs, amounts and
disburse­ments as provided herein and in the other Loan Instruments
(hereinafter defined).

absolute or contingent, direct or indirect, liquidated or unliquidated, or
otherwise (all indebtedness and liabilities secured hereby being hereinafter

                    1.2.     General
Covenants and Representations. Mortgagor covenants, represents and warrants that as of the date

laws of the State of Indiana [and is in good standing under the laws of the
State of Illinois;] (b) Mortgagor is seized of an indefeasible estate in fee

has good and absolute title to it and the balance of the Mortgaged Property
free and clear of all liens, security interests, charges and encumbrances

writing being hereinafter referred to as the “Permitted
Encumbrances”); (c) Mortgagor has good right, full power and lawful

                    1.4.     Taxes
and Other Charges. 

                    1.4.1.     Taxes
and Assessments.
Mortgagor shall pay promptly when due all taxes, assessments, rates, dues,
charges, fees, levies, fines, impositions, liabilities, obligations, liens and
encumbrances of every kind and nature whatsoever now or hereafter imposed,
levied or assessed upon or against the Mortgaged Property or any part thereof,
or upon or against this Mortgage or Mortgagor’s Liabilities or upon or against
the interest of Lender in the Mortgaged Property, as well as all taxes,
assessments and other governmental charges levied and imposed by the United
States of America or any state, county, municipality or other taxing authority
upon or in respect of the Mortgaged Property or any part thereof; provided,
however, that unless compliance with applicable laws requires that taxes,
assessments or other charges must be paid as a condition to protesting or
contesting the amount thereof, Mortgagor may in good faith, by appropriate
proceedings commenced within ninety (90) days of the due date of such amounts
and thereafter diligently pursued, contest the validity, applicability or
amount of any asserted tax, assessment or other charge and pending such contest
Mortgagor shall not be deemed in default hereunder if on or before the due date
of the asserted tax or assessment, Mortgagor shall first either (i) deposit
with Lender a bond or other security satisfactory to Lender in the amount of
150% of the amount of such tax or assessment or (ii) obtain an endorsement, in
form and substance satisfactory to Lender, to the loan policy of title
insurance issued to Lender insuring the lien of this Mortgage, insuring over
such tax or assessment. Mortgagor shall pay the disputed or contested tax,
assessment or other charge and all interest and penalties due in respect
thereof on or before the date any adjudication of the validity or amount thereof
becomes final and in any event no less than thirty (30) days prior to any
forfeiture or sale of the Mortgaged Property by reason of such non-payment.
Upon Lender’s request, Mortgagor will promptly file, if it has not theretofore
filed, such petition, application or other instrument as is necessary to cause
the Land and Improvements to be taxed as a separate parcel or parcels which
include no property not a part of the Mortgaged Property. 

                    1.4.2.     Taxes
Affecting Lender’s Interest. If any state, federal, municipal or other governmental law, order,
rule or regulation, which becomes effective subsequent to the date hereof, in
any manner changes or modifies existing laws governing the taxation of
mortgages or debts secured by mortgages, or the manner of collecting taxes, so
as to impose on Lender a tax by reason of its ownership of any or all of the
Loan Instruments or measured by the principal amount of the Notes, requires or
has the practical effect of requiring Lender to pay any portion of the real
estate taxes levied in respect of the Mortgaged Property to pay any tax levied
in whole or in part in substitution for real estate taxes or otherwise affects
materially and adversely the rights of Lender in respect of the Notes, this
Mortgage or the other Loan Instruments, Mortgagor’s Liabilities and all
interest accrued thereon shall, upon thirty (30) days’ notice, become due and
payable forthwith at the option of Lender, whether 

3

or not there shall have occurred an Event of
Default, provided, however, that, if Mortgagor may, without violating or
causing a violation of such law, order, rule or regulation, pay such taxes or
other sums as are necessary to eliminate such adverse effect upon the rights of
Lender and does pay such taxes or other sums when due, Lender may not elect to
declare due Mortgagor’s Liabilities by reason of the provisions of this Section
1.4.2. 

                    1.4.3.     Tax
Escrow. If
directed by Lender in writing, Mortgagor shall, in order to secure the
performance and discharge of Mortgagor’s obligations under this Section 1.4,
but not in lieu of such obligations, deposit with Lender on the first day of
each calendar month throughout the term of the Loan, deposits, in amounts set
by Lender from time to time by written notice to Mortgagor, in order to
accumulate funds sufficient to permit Lender to pay all annual ad valorem
taxes, assessments and charges of the nature described in Section 1.4.1 at
least thirty (30) days prior to the date or dates on which they shall become
delinquent. Mortgagor hereby pledges to Lender, and grants to Lender a security
interest in, any and all such deposits as security for the Loan. The taxes,
assessments and charges for purposes of this Section 1.4.3 shall, if Lender so
elects, include, without limitation, water and sewer rents. Mortgagor shall
procure and deliver to Lender when issued all statements or bills for such
obligations. Upon demand by Lender, Mortgagor shall deliver to Lender such
additional monies as are required to satisfy any deficiencies in the amounts
necessary to enable Lender to pay such taxes, assessments and similar charges
thirty (30) days prior to the date they become delinquent. Lender shall pay
such taxes, assessments and other charges as they become due to the extent of
the funds on deposit with Lender from time to time and provided Mortgagor has
delivered to Lender the statements or bills therefor. In making any such
payments, Lender shall be entitled to rely on any bill issued in respect of any
such taxes, assessments or charges without inquiry into the validity, propriety
or amount thereof and whether delivered to Lender by Mortgagor or otherwise
obtained by Lender. Any deposits received pursuant to this Section 1.4.3 shall
not be, nor be deemed to be, trust funds, but may be commingled with the
general funds of Lender and Lender shall have no obligation to pay interest on
amounts deposited with Lender pursuant to this Section 1.4.3. If any Event of
Default occurs, any part or all of the amounts then on deposit or thereafter
deposited with Lender under this Section 1.4.3 may at Lender’s option be
applied to payment of Mortgagor’s Liabilities in such order as Lender may
determine. 

                    1.4.4.     No
Credit Against the Indebtedness Secured Hereby. Mortgagor shall not claim, demand or be
entitled to receive any credit against the amounts payable under the terms of
the Guaranty or on any of Mortgagor’s Liabilities for any of the taxes,
assessments or similar impositions assessed against the Mortgaged Property or
any part thereof or that are applicable to Mortgagor’s Liabilities or to
Lender’s interest in the Mortgaged Property.

                    1.5
       Mechanic’s and Other Liens. Mortgagor shall not permit or suffer any
mechanic’s, laborer’s, materialman’s, statutory or other lien or encumbrance
(other than any lien for taxes and assessments not yet due) to be created upon
or against the Mortgaged Property, provided, however, that Mortgagor may in
good faith, by appropriate proceeding, contest the validity, applicability or
amount of any asserted lien and, pending such contest, Mortgagor shall not be
deemed to be in default hereunder if Mortgagor shall first obtain an
endorsement, in form and substance satisfactory to Lender, to the loan policy
of title insurance issued to Lender insuring over such lien, or, if no such
loan policy shall have been issued, then Mortgagor shall deposit with Lender a
bond or other security satisfactory to Lender in the amount of 150% of the
amount of such lien. Mortgagor shall pay the disputed amount and all interest
and penalties due in respect thereof on or before the date any adjudication of
the validity or amount thereof becomes final and, in any event, no less than
thirty (30) days prior to any foreclosure sale of the Mortgaged Property or the
exercise of any other remedy by such claimant against the Mortgaged Property. 

                    1.6         Insurance
and Condemnation. 

	
  

 	
  

 
	
                     1.6.1.     Hazard
 Insurance.
 Mortgagor shall, at its sole cost and expense, obtain for, deliver to, assign
 to and maintain for the benefit of Lender, until Mortgagor’s Liabilities are
 paid in full, policies of hazard insurance, in an amount which shall be not
 less than 100% of the full insurable replacement cost of the Mortgaged
 Property (except the Land), insuring on a replacement cost basis the
 Mortgaged Property with “causes of loss-special form” coverage and insuring
 against such other hazards, casualties and contingencies as Lender may
 require, including without limitation, if requested by Lender, earthquake,
 and, if all or any part of the Mortgaged Property shall at any time be
 located within an area identified by the government of the United States or
 any agency thereof as having special flood hazards and for which flood
 insurance is available, flood. If any such policy shall contain a
 co-insurance clause it shall also contain an agreed amount or stipulated
 value endorsement. All policies of hazard insurance shall contain a “lender’s
 loss payable” endorsement and shall provide that no losses shall be payable
 to any other parties without Lender’s prior written consent. The form of such
 policies, the amounts and the companies issuing them shall be acceptable to
 Lender. Originals or certified copies of all policies shall be delivered to
 and retained by Lender. Mortgagor shall pay on or before the due dates
 thereof premiums on all insurance policies and on any renewals thereof. In
 the event of loss, Mortgagor will give immediate written notice to Lender and
 Lender may make proof of loss if not made promptly by Mortgagor (for which
 purpose Mortgagor hereby irrevocably appoints Lender as its attorney-in-fact).
 In the event of the foreclosure of this Mortgage or any other transfer of
 title to the Mortgaged Property in full or partial satisfaction of
 Mortgagor’s Liabilities, all right, title and interest of Mortgagor in and to
 all insurance policies and renewals thereof then in force shall pass to the
 purchaser

 or grantee. All such policies
 shall provide that they shall not be modified, cancelled or terminated
 without at least thirty (30) days’ prior written notice to Lender from the
 insurer. 

 	
  

 
	
  

 	
  

 
	
                     1.6.2.     Other
 Insurance.
 Mortgagor shall, at its sole cost and expense, obtain for, deliver to, assign
 to and maintain for the benefit of, Lender, until Mortgagor’s Liabilities are
 paid for in full, (i) commercial general liability insurance in such amounts
 as Lender may specify, together with workers compensation and employer’s
 liability insurance, naming Lender as additional insured, [(ii) a business
 interruption insurance policy covering loss of rents [loss of income] at a limit of 100%, in
 an amount not less than all rent and other charges payable by the tenants of
 the Mortgaged Property [gross income]
 (based on a fully leased [fully
 operational] building) for a period of one (1) year, together with
 such assignments of the proceeds of such policy as Lender may require,] (iii)
 boiler and machinery insurance, if requested by Lender, and (iv) such other
 policies of insurance relating to the Mortgaged Property and the use and operation
 thereof as Lender may require, including dramshop, all in form and amounts,

 of Loss.
 Lender is hereby authorized and empowered, at its option, to adjust or
 compromise any loss of more than $250,000 under any insurance policies
 covering or relating to the Mortgaged Property and to collect and receive the
 proceeds from any such policy or policies (and deposit such proceeds as
 provided in Section 1.6.5). Mortgagor hereby irrevocably appoints Lender as
 its attorney-in-fact for the purposes set forth in the preceding sentence.
 Each insurance company is hereby authorized and directed to make payment (i)
 of 100% of all such losses of more than said amount directly to Lender alone
 and (ii) of 100% of all such losses of said amount or less directly to
 Mortgagor alone, and in no case to Mortgagor and Lender jointly. After
 deducting from such insurance proceeds any expenses incurred by Lender in the
 collection and settlement thereof, including without limitation attorneys’
 and adjusters’ fees and charges, Lender shall apply the net proceeds as
 provided in Section 1.6.5. Lender shall not be responsible for any failure to
 collect any insurance proceeds due under the terms of any policy regardless
 of the cause of such failure. 

 	
  

 
	
  

 	
  

 
	
                     1.6.4.     Condemnation
 Awards.
 Lender shall be entitled to all compensation, awards, damages, claims, rights
 of action and proceeds of, or on account of, (i) any damage or taking,

 part thereof, (ii) damage to the Mortgaged Property by reason of the taking,
 pursuant to the power of eminent domain, of other property, or (iii) the
 alteration of the grade of any street or highway on or about the Mortgaged
 Property. Lender is hereby authorized, at its option, to commence, appear in
 and prosecute in its own or Mortgagor’s name any action or proceeding
 relating to any such compensation, awards, damages, claims,

 rights of action and proceeds
 and to settle or compromise any claim in connection therewith. Mortgagor
 hereby irrevocably appoints Lender as its attorney-in-fact for the purposes
 set forth in the preceding sentence. Lender after deducting from such
 compensation, awards, damages, claims, rights of action and proceeds all its
 expenses, including attorneys’ fees, may apply such net proceeds (except as
 otherwise provided in Section 1.6.5 of this Mortgage) to payment of
 Mortgagor’s Liabilities in such order and manner as Lender may elect.
 Mortgagor agrees to execute such further assignments of any compensation
 awards, damages, claims, rights of action and proceeds as Lender may require.
 

 	
  

 
	
  

 	
  

 
	
                     1.6.5.     Repair;
 Proceeds of Casualty Insurance and Eminent Domain. If all or any part of the Mortgaged
 Property shall be damaged or destroyed by fire or other casualty or shall be
 damaged or taken through the exercise of the power of eminent domain or other

 diligence restore and repair the Mortgaged Property whether or not the
 proceeds, award or other compensation are sufficient to pay the cost of such
 restoration or repair. At Lender’s election, to be exercised by written
 notice to Mortgagor within thirty (30) days following Lender’s unrestricted
 receipt in cash or the equivalent thereof of said proceeds, award or other
 compensation, the entire amount of said proceeds, award or compensation shall
 either (i) be applied to Mortgagor’s Liabilities in such order and manner as
 Lender may elect or (ii) be made available to Mortgagor on such terms and
 conditions as Lender may impose, including without limitation the terms and
 conditions set forth in this Section 1.6.5, for the purpose of financing the
 cost of restoration or repair with any excess to be applied to Mortgagor’s
 Liabilities. Notwithstanding any other provision of this Section 1.6.5, if an
 Event of Default shall be existing at the time of such casualty, taking or
 other event or if an Event of Default occurs thereafter, Lender shall have
 the right to immediately apply all insurance proceeds, awards or compensation
 to the payment of Mortgagor’s Liabilities in such order and manner as Lender
 may determine. Lender shall have the right at all times to apply such net
 proceeds to the cure of any Event of Default or the performance of any
 obligations of Mortgagor under the Loan Instruments. 

 	
  

 
	
  

 	
  

 
	
                     1.6.6.     [Proceeds
 of Business Interruption and Rental Insurance. The net proceeds of business
 interruption and rental insurance shall be paid to Lender for application
 first to Mortgagor’s Liabilities in such order and manner as Lender may elect
 and then to the creation of reserves for future payments of Mortgagor’s
 Liabilities in such amounts as Lender deems necessary with the balance to be
 remitted to Mortgagor subject to such controls as Lender may deem necessary
 to assure that said balance is used to discharge accrued and to be accrued
 expenses of operation and maintenance of the Mortgaged Property.]

                     1.6.7.     Renewal
 of Policies.
 At least thirty (30) days prior to the expiration date of any policy
 evidencing insurance required under this Section 1.6.7, a renewal thereof

 due on such renewal policy or substitute policy. 

 	
  

 
	
  

 	
  

 
	
                     1.6.8.     Insurance
 Escrow. If
 directed by Lender in writing, Mortgagor shall, in order to secure the
 performance and discharge of Mortgagor’s obligations under this Section 1.6,
 but not in lieu of such obligations, deposit with Lender on the first day of
 each calendar month throughout the term of the Loan, a sum in an amount
 determined by Lender from time to time by written notice to Mortgagor, in

 payable in connection with the insurance required hereunder at least thirty
 (30) days prior to the date or dates on which they shall become due.
 Mortgagor hereby pledges to Lender, and grants to Lender a security interest
 in, any and all such deposits as security for the Loan. Upon demand by
 Lender, Mortgagor shall deliver to Lender such additional monies as are
 required to satisfy any deficiencies in the amounts necessary to enable
 Lender to pay such premiums thirty (30) days prior to the date they shall
 become due. Any deposits received pursuant to this Section 1.6.8 shall not
 be, nor be deemed to be, trust funds, but may be commingled with the general
 funds of Lender and Lender shall have no obligation to pay interest on
 amounts deposited with Lender pursuant to this Section 1.6.8. If any Event of
 Default occurs, any part or all of the amounts then on deposit or thereafter
 deposited with Lender under this Section 1.6.8 may at Lender’s option be
 applied to payment of Mortgagor’s Liabilities in such order as Lender may
 determine. 

 	
  

 

                    1.7.       Non-Impairment
of Lender’s Rights. Nothing contained in this Mortgage shall be deemed to limit or
otherwise affect any right or remedy of Lender under any provision of this
Mortgage or of any statute or rule of law to pay and, upon Mortgagor’s failure
to pay the same, Lender may pay any amount required to be paid by Mortgagor
under Sections 1.4, 1.5 and 1.6 and the amount so paid by Lender shall bear
interest at the Default Rate (as defined in the Notes), and, together with
interest, shall be added to Mortgagor’s Liabilities. Mortgagor shall pay to
Lender on demand the amount so paid by Lender, together with all accrued and
unpaid interest thereon. The provisions of Section 1.4.3 are solely for the
added protection of Lender and entail no responsibility on Lender’s part beyond
the allowing of due credit as specifically provided therein. Upon assignment of
this Mortgage, any funds on hand shall be turned over to the assignee and any
responsibility of Lender with respect to such funds shall terminate. 

                    1.8.       Care
of the Mortgaged Property. Mortgagor shall preserve and maintain the Mortgaged Property in good
and first class condition and repair. Mortgagor shall not, without the prior
written consent of Lender, permit, commit or suffer any waste, impairment or
deterioration of the Mortgaged Property or of any part thereof, and will not
take any action which will increase the risk of fire or other hazard to the
Mortgaged

or Encumbrance of the Mortgaged Property. Mortgagor shall not permit or suffer to
occur any sale, assignment, conveyance, transfer, mortgage, lease (other than
leases made in accordance with the provisions of this Mortgage) or encumbrance
of, or any contract for any of the foregoing on an installment basis or
otherwise pertaining to, the Mortgaged Property, any part thereof, any interest
therein, the beneficial interest in Mortgagor or in any trust holding title to
the Mortgaged Property or any interest in a corporation, partnership or other
entity which owns all or part of the Mortgaged Property, whether by operation
of law or otherwise, without the prior written consent of Lender having been
obtained (i) to the sale, assignment, conveyance, mortgage, lease, option,
encumbrance or other transfer and (ii) to the form and substance of any
instrument evidencing or contracting for any such sale, assignment, conveyance,
mortgage, lease, option, encumbrance or other transfer. Mortgagor shall not,
without the prior written consent of Lender, further assign or permit to be
assigned the rents from the Mortgaged Property, and any such assignment without
the prior express written consent of Lender shall be null and void. Mortgagor
shall not permit any interest in any lease of the Mortgaged Property to be
subordinated to any encumbrance on the Mortgaged Property other than the Loan
Instruments and any such subordination shall be null and void. Mortgagor agrees
that in the event the ownership of the Mortgaged Property, any interest therein
or any part thereof becomes vested in a person other than Mortgagor, Lender
may, without notice to Mortgagor, deal in any way with such successor or
successors in interest with reference to this Mortgage, the Notes, the Loan
Instruments and Mortgagor’s Liabilities without in any way vitiating or
discharging Mortgagor’s liability hereunder or Mortgagor’s Liabilities. No sale
of the Mortgaged Property, no forbearance to any person with respect to this
Mortgage, and no extension to any person of the time for payment of the Notes
or any other Mortgagor’s Liabilities given by Lender shall operate to release,
discharge, modify, change or affect the original liability of Mortgagor, either
in whole or in part, except to the extent specifically agreed in writing by
Lender. 

                    1.10.     Further
Assurances. At
any time and from time to time, upon Lender’s request, Mortgagor shall make,
execute and deliver, or cause to be made, executed and delivered, to Lender,
and where appropriate shall cause to be recorded, registered or filed, and from
time to time thereafter to be re-recorded, re-registered and refiled at such
time and in such offices and places as shall be deemed desirable by Lender, any
and all such further mortgages, security agreements, financing statements,
instruments of further assurance, certificates and other documents as Lender
may consider necessary or desirable in order to effectuate or perfect, or to
continue and preserve the obligations under, the Guaranty, this Mortgage, any
other Loan Instrument and any instrument evidencing or securing Mortgagor’s
Liabilities, and the lien of this Mortgage as a lien upon all of the Mortgaged
Property, whether now owned or hereafter

acquired by Mortgagor, and unto all and every
person or persons deriving any estate, right, title or interest under this
Mortgage. Upon any failure by Mortgagor to do so, Lender may make, execute,
record, register, file, re-record, re-register or re-file any and all such
mortgages, instruments, certificates and documents for and in the name of
Mortgagor, and Mortgagor hereby irrevocably appoints Lender the agent and
attorney-in-fact of Mortgagor to do so. 

	
  

 	
  

 	
  

 
	
  

 	
 1.11.     Security
 Agreement and Financing Statements.

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (a)         Mortgagor
 (as debtor) hereby grants to Lender (as creditor and secured party) a
 security interest under the Uniform Commercial Code in all fixtures,
 machinery, appliances, equipment, furniture and personal property of every
 nature whatsoever constituting part of the Mortgaged Property. Mortgagor
 shall execute any and all documents, including without limitation financing
 statements pursuant to the Uniform Commercial Code, as Lender may request to
 preserve, maintain and perfect the priority of the first lien and security
 interest created hereby on property which may be deemed personal property or
 fixtures, and shall pay to Lender on demand any expenses incurred by Lender
 in connection with the preparation, execution and filing of any such
 documents. Mortgagor hereby authorizes and empowers Lender and irrevocably
 appoints Lender the agent and attorney-in-fact of Mortgagor to execute and
 file, on Mortgagor’s behalf, all financing statements and refilings and
 continuations thereof as Lender deems necessary or advisable to create,
 preserve and protect such lien. When and if Mortgagor and Lender shall
 respectively become the debtor and secured party in any Uniform Commercial
 Code financing statement affecting the Mortgaged Property (or Lender takes
 possession of personal property delivered by Mortgagor where possession is
 the means of perfection of the security interest), then, at Lender’s sole
 election, this Mortgage shall be deemed a security agreement as defined in
 such Uniform Commercial Code, and the remedies for any violation of the
 covenants, terms and conditions of the agreements herein contained shall be
 as prescribed herein or by general law, or, as to such part of the security
 which is also reflected in such financing statement, by the specific
 statutory consequences now or hereafter enacted and specified in the Uniform
 Commercial Code. 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)         Without
 limitation of the foregoing, if an Event of Default occurs, Lender shall be
 entitled immediately to exercise all remedies available to it under the
 Uniform Commercial Code and this Section 1.11. Mortgagor shall, in such event
 and if Lender so requests, assemble the tangible personal property at
 Mortgagor’s

 expense, at a convenient place
 designated by Lender. Lender may publicly or privately sell or otherwise
 dispose of such fixtures, machinery, appliances, equipment, furniture and
 personal property upon such terms and in such manner as Lender may require.
 Mortgagor shall pay all expenses incurred by Lender in the collection of such
 indebtedness, including attorneys’ fees and legal expenses, and in the repair
 of any real estate or other property to which any of the tangible personal
 property may be affixed. If any notification of intended disposition of any
 of the personal property is required by law, such notification shall be
 deemed reasonable and proper if given at least ten (10) days before such
 disposition. Any proceeds of the disposition of any of the personal property
 may be applied by Lender to the payment of the reasonable expenses of
 retaking, holding, preparing for sale and selling the personal property,
 including attorneys’ fees and legal expenses, and any balance of such
 proceeds may be applied by Lender toward the payment of such of Mortgagor’s
 Liabilities, and in such order of application, as Lender may from time to
 time elect. If an Event of Default occurs, Lender shall have the right to
 exercise and shall automatically succeed to all rights of Mortgagor with
 respect to intangible personal property subject to the security interest
 granted herein. Any party to any contract subject to the security interest
 granted herein shall be entitled to rely on the rights of Lender without the
 necessity of any further notice or action by Mortgagor. Lender shall not by reason
 of this Mortgage or the exercise of any right granted hereby be obligated to
 perform any obligation of Mortgagor with respect to any portion of the
 personal property nor shall Lender be responsible for any act committed by
 Mortgagor, or any breach or failure to perform by Mortgagor with respect to
 any portion of the personal property.

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (c)         Mortgagor
 and Lender agree that the filing of a financing statement in the records
 normally having to do with personal property shall never be construed as in
 any way derogating from or impairing the express declaration and intention of
 the parties hereto, hereinabove stated, that everything used in connection
 with the production of income from the Mortgaged Property and/or adapted for
 use therein and/or which is described or reflected in this Mortgage is, and
 at all times and for all purposes and in all proceedings, legal or equitable,
 shall be regarded as part of the real estate encumbered by this Mortgage
 irrespective of whether (i) any such item is physically attached to the Land
 or Improvements, (ii) serial numbers are used for the better identification
 of certain equipment items capable of being thus identified in a recital

 contained herein or in any
 list filed with Lender, or (iii) any such item is referred to or reflected in
 any such financing statement so filed at any time. Similarly, the mention in
 any such financing statement of (1) rights in or to the proceeds of any fire
 and/or hazard insurance policy, or (2) any award in eminent domain
 proceedings for a taking or for loss of value, or (3) Mortgagor’s interest as
 lessor in any present or future lease or rights to income growing out of the
 use and/or occupancy of the Mortgaged Property, whether pursuant to lease or
 otherwise, shall never be construed as in any way altering any of the rights
 of Lender as determined by this instrument or adversely affecting the
 priority of Lender’s lien granted hereby or by any other recorded document.
 Any such mention in any such financing statement is declared to be for the
 protection of Lender in the event any court or judge shall at any time hold
 with respect to clauses (1), (2) or (3) above, that notice of Lender’s
 priority of interest, to be effective against a particular class of persons,
 including, but not limited to, the federal government and any subdivisions or
 entity of the federal government, must be filed in the Uniform Commercial
 Code records.

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 1.12.     Assignment
 of Rents.

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (a)         The
 assignment of rents, income and other benefits contained in Section (G) of
 the Granting Clauses of this Mortgage shall be fully operative without any
 further action on the part of either party, and, specifically, Lender shall
 be entitled, at its option, upon the occurrence of an Event of Default
 hereunder, to all rents, income and other benefits from the Mortgaged
 Property, whether or not Lender takes possession of such property. Mortgagor
 hereby further grants to Lender the right effective upon the occurrence of an
 Event of Default to do any or all of the following, at Lender’s option: (i)
 enter upon and take possession of the Mortgaged Property for the purpose of
 collecting the rents, income and other benefits; (ii) dispossess by the usual
 summary proceedings any tenant defaulting in the payment thereof to Lender;
 (iii) lease the Mortgaged Property or any part thereof; (iv) repair, restore
 and improve the Mortgaged Property; and (v) apply the rents, income and other
 benefits, after payment of certain expenses and capital expenditures relating
 to the Mortgaged Property, on account of Mortgagor’s Liabilities in such
 order and manner as Lender may elect. Such assignment and grant shall
 continue in effect until Mortgagor’s Liabilities are paid in full, the
 execution of this Mortgage constituting and evidencing the irrevocable
 consent of 

 	
  

 

12

 Mortgagor to the entry upon
 and taking possession of the Mortgaged Property by Lender pursuant to such
 grant, whether or not foreclosure proceedings have been instituted. Neither
 the exercise of any rights under this section by Lender nor the application
 of any such rents, income or other benefits to payment of Mortgagor’s
 Liabilities shall cure or waive any Event of Default or notice provided for
 hereunder, or invalidate any act done pursuant hereto or pursuant to any such
 notice, but shall be cumulative of all other rights and remedies.
 Notwithstanding the foregoing, so long as no Event of Default has occurred or
 is continuing, Mortgagor shall have the right and authority to continue to
 collect the rents, income and other benefits from the Mortgaged Property as
 they become due and payable but not more than thirty (30) days prior to the
 due date thereof. The existence or exercise of such right of Mortgagor to
 collect said rents, income and other benefits shall not operate to
 subordinate this assignment to any subsequent assignment of said rents,
 income or other benefits, in whole or in part, by Mortgagor, and any such
 subsequent assignment by Mortgagor shall be subject to the rights of Lender
 hereunder.

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)        Mortgagor
 shall not permit any rent under any lease of the Mortgaged Property to be
 collected more than thirty (30) days in advance of the due date thereof and,
 upon any receiver, Lender, anyone claiming by, through or under Lender or any
 purchaser at a foreclosure sale coming into possession of the Mortgaged
 Property, no tenant shall be given credit for any rent paid more than thirty
 (30) days in advance of the due date thereof. Mortgagor shall act promptly to
 enforce all available remedies against any delinquent lessee so as to protect
 the interest of the lessor under the leases and to preserve the value of the
 Mortgaged Property. 

 	
  

 

                    1.13.     After-Acquired
Property. To
the extent permitted by, and subject to, applicable law, the lien of this
Mortgage, including without limitation the security interest created under
Section 1.11, shall automatically attach, without further act, to all property
hereafter acquired by Mortgagor located in or on, or attached to, or used or
intended to be used in connection with, or with the operation of, the Mortgaged
Property or any part thereof. 

                    1.14.     Leases
Affecting Mortgaged Property. 

	
  

 	
  

 	
  

 
	
  

 	
 (a)        Mortgagor
 shall comply with and perform in a complete and timely manner all of its
 obligations as landlord under all leases affecting the Mortgaged Property or
 any part thereof. Mortgagor shall give notice to Lender of any default by the
 landlord under any lease affecting the Mortgaged Property promptly upon the

 occurrence of such default,
 but, in any event, in such time to afford Lender an opportunity to cure any
 such default prior to the tenant having any right to terminate the lease.
 Each of the leases shall contain a provision requiring the tenant to notify
 Lender of any default by landlord and granting an opportunity for a reasonable
 time after such notice to cure such default prior to any right accruing to
 the tenant to terminate such lease. Mortgagor, if requested by Lender, shall
 furnish promptly to Lender (i) original or certified copies of all such
 leases now existing or hereafter created, as amended from time to time, and
 (ii) a current rent roll in form satisfactory to Lender. Lender shall have
 the right to notify at any time and from time to time any tenant of the
 Mortgaged Property of any provision of this Mortgage. 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)       The
 assignment contained in Section (H) of the Granting Clauses shall not be
 deemed to impose upon Lender any of the obligations or duties of the landlord
 or Mortgagor provided in any lease. 

 	
  

 

                    1.15.     Management
of Mortgaged Property. Mortgagor shall cause the Mortgaged Property to be managed at all
times in accordance with sound business practice. 

                    1.16.     Execution
of Leases.
Mortgagor shall not permit any leases to be made of the Mortgaged Property or
existing leases to be modified, terminated, extended or renewed without the
prior written consent of Lender. 

                    1.17      Expenses. Mortgagor shall pay when due and payable,
and otherwise on demand made by Lender, all appraisal fees, recording fees,
taxes, brokerage fees and commissions, abstract fees, title insurance fees,
escrow fees, attorneys’ fees, court costs, documentary and expert evidence,
fees of inspecting architects and engineers, and all other costs and expenses
of every character which have been incurred or which may hereafter be incurred
by Lender in connection with any of the following: 

	
  

 	
  

 	
  

 
	
  

 	
 (a)       Any
 court or administrative proceeding involving Mortgagor, the Mortgaged
 Property or the Loan Instruments to which Lender is made a party or is
 subject to subpoena by reason of its being a holder of any of the Loan
 Instruments, including without limitation bankruptcy, insolvency,
 reorganization, probate, eminent domain, condemnation, building code and
 zoning proceedings; 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)       Any
 court or administrative proceeding or other action undertaken by Lender to
 enforce any remedy or to collect any indebtedness due under this Mortgage or
 any of the other Loan

 Instruments following a
 default thereunder, including without limitation a foreclosure of this
 mortgage or a public or private sale under the Uniform Commercial Code; 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (c)     Any
 remedy exercised by Lender following an Event of Default including
 foreclosure of this Mortgage and actions in connection with taking possession
 of the Mortgaged Property or collecting rents assigned hereby; 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (d)     Any
 activity in connection with any request by Mortgagor or anyone acting on
 behalf of Mortgagor that Lender consent to a proposed action which, pursuant
 to this Mortgage or any of the other Loan Instruments may be undertaken or
 consummated only with the prior consent of Lender, whether or not such
 consent is granted; or 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (e)     Any
 negotiation undertaken between Lender and Mortgagor or anyone acting on
 behalf of Mortgagor pertaining to the existence or cure of any default under
 or the modification or extension of any of the Loan Instruments. 

 	
  

 
	
  

 	
  

 	
  

 

          If
Mortgagor fails to pay said costs and expenses as above provided, Lender may
elect, but shall not be obligated, to pay the costs and expenses described in
this Section 1.17, and if Lender does so elect, then the amounts paid by Lender
shall bear interest at the Default Rate and, together with interest, shall be
added to Mortgagor’s Liabilities. Mortgagor will, upon demand by Lender,
reimburse Lender for all such expenses, together with all accrued and unpaid
interest thereon. In the event of foreclosure hereof, Lender shall be entitled
to add to the indebtedness found to be due by the court a reasonable estimate
of such expenses to be incurred after entry of the decree of foreclosure. To
the extent permitted by law, Mortgagor agrees to hold harmless Lender against
and from, and reimburse it for, all claims, demands, liabilities, losses,
damages, judgments, penalties, costs and expenses, including without limitation
attorneys’ fees, which may be imposed upon, asserted against, or incurred or
paid by it by reason of or in connection with any bodily injury or death or
property damage occurring in or upon or in the vicinity of the Mortgaged
Property through any cause whatsoever, or asserted against it on account of any
act performed or omitted to be performed hereunder, or on account of any transaction
arising out of or in any way connected with the Mortgaged Property, this
Mortgage, the other Loan Instruments or any of Mortgagor’s Liabilities. 

                    1.18     Lender’s
Performance of Mortgagor’s Obligations. 

	
  

 	
  

 	
  

 
	
  

 	
 (a)      If
 Mortgagor fails to pay any tax, assessment, encumbrance or other imposition,
 or to furnish insurance hereunder, or to perform any other covenant,
 condition or term in this Mortgage, the Guaranty or any other Loan
 Instrument, Lender may, but shall not 

 	
  

 

15

LaSalle Bank
National Association

 be obligated to, pay, obtain
 or perform the same. All payments made, whether such payments are regular or
 accelerated payments, and costs and expenses incurred or paid by Lender in
 connection therewith shall be due and payable immediately. The amounts so
 incurred or paid by Lender shall bear interest at the Default Rate and,
 together with interest, shall be added to Mortgagor’s Liabilities. Lender is
 hereby empowered to enter and to authorize others to enter upon the Mortgaged
 Property or any part thereof for the purpose of performing or observing any
 covenant, condition or term that Mortgagor has failed to perform or observe,
 without thereby becoming liable to Mortgagor or any person in possession
 holding under Mortgagor. Performance or payment by Lender of any obligation
 of Mortgagor shall not relieve Mortgagor of such obligation or of the
 consequences of having failed to perform or pay the same and shall not effect
 the cure of any Event of Default. 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)       Without
 limitation of the foregoing, unless Mortgagor provides Lender with evidence
 of the insurance coverage required by this Mortgage, Lender may purchase
 insurance at Mortgagors’ expense to protect Lender’s interests in the Mortgaged
 Property. This insurance may, but need not, protect Mortgagor’s interest. The
 coverage that Lender purchases may not pay any claim that Mortgagor may make
 or any claim that is made against Mortgagor in connection with the Mortgaged
 Property. Mortgagor may later cancel any insurance purchased by Lender, but
 only after providing Lender with evidence that Mortgagor has obtained
 insurance as required by this Mortgage. If Lender purchases insurance for the
 Mortgaged Property, Mortgagor will be responsible for the costs of such
 insurance, including interest and any other charges that may be imposed in
 connection with the placement of such insurance, until the effective date of
 the cancellation or expiration of such insurance. Without limitation of any
 other provision of this Mortgage, the cost of such insurance shall be added
 to the indebtedness secured hereby. The cost of the insurance may be more
 than the cost of insurance Mortgagor may be able to obtain on its own. 

 	
  

 

                    1.19.     Payment
of Superior Liens. To the extent that Lender, after the date hereof, pays any sum due
under any provision of law or instrument or document creating any lien superior
or equal in priority in whole or in part to the lien of this Mortgage, Lender
shall have and be entitled to a lien on the premises equal in parity with that
discharged, and Lender shall be subrogated to and receive and enjoy all rights
and liens possessed, held or enjoyed by, the holder of such lien, which shall
remain in existence and 

16

LaSalle Bank
National Association

benefit Lender to secure the Guaranty, and
all obligations and liabilities secured hereby. Lender shall be subrogated,
notwithstanding their release of record, to mortgages, trust deeds, superior
titles, vendors’ liens, mechanics’ and materialmen’s liens, charges,
encumbrances, rights and equities on the Mortgaged Property to the extent that
any obligation under any thereof is paid or discharged with proceeds of
disbursements or advances subject to the Guaranty or other indebtedness secured
hereby. 

                    1.20.     Use
of the Mortgaged Property. Mortgagor shall not suffer or permit the Mortgaged Property, or any
portion thereof, to be used for any purpose other than for the purposes for
which it is currently being used and, without limitation of the foregoing,
Mortgagor shall not use or permit the use of the Mortgaged Property or any
portion thereof for any unlawful purpose. 

                    1.21.     Litigation
Involving Mortgaged Property. Mortgagor shall promptly notify Lender of any litigation,
administrative procedure or proposed legislative action initiated against
Mortgagor or the Mortgaged Property or in which the Mortgaged Property is
directly or indirectly affected including any proceedings which seek to (i)
enforce any lien against the Mortgaged Property, (ii) correct, change or
prohibit any existing condition, feature or use of the Mortgaged Property,
(iii) condemn or demolish the Mortgaged Property, (iv) take, by the power of eminent
domain, any portion of the Mortgaged Property or any property which would
damage the Mortgaged Property, (v) modify the zoning applicable to the
Mortgaged Property, or (vi) otherwise adversely affect the Mortgaged Property.
Mortgagor shall initiate or appear in any legal action or other appropriate
proceedings when necessary to protect the Mortgaged Property from damage.
Mortgagor shall, upon written request of Lender, represent and defend the
interests of Lender in any proceedings described in this Section 1.21 or, at
Lender’s election, pay the fees and expenses of any counsel retained by Lender
to represent the interest of Lender in any such proceedings, in which event
such fees and expenses shall be added to Mortgagor’s Liabilities and shall bear
interest at the Default Rate. 

                    1.22.     Environmental
Matters.

	
  

 	
  

 	
  

 
	
  

 	
 (a)       Mortgagor
 represents and warrants that Mortgagor has not generated, used, stored,
 treated, transported, manufactured, handled, produced or disposed of any Hazardous
 Materials (as defined in the Loan Agreement), on or off the Mortgaged
 Property in any manner which at any time violates any Environmental Law (as
 defined in the Loan Agreement) or any license, permit, certificate, approval
 or similar authorization thereunder and the operations of the Mortgagor
 comply in all material respects with all Environmental Laws and all licenses,
 permits, certificates, approvals and similar authorizations thereunder; (ii)
 there has been no investigation, proceeding, complaint, order, directive,
 claim, citation or notice by any governmental authority or any other Person,
 nor is any pending or to the best of the Mortgagor’s knowledge threatened,
 and Mortgagor shall immediately notify

 Lender upon becoming aware of
 any such investigation, proceeding, complaint, order, directive, claim,
 citation or notice and take prompt and appropriate actions to respond
 thereto, with respect to any non-compliance with or violation of the
 requirements of any Environmental Law by Mortgagor or the release, spill or
 discharge, threatened or actual, of any Hazardous Materials or the
 generation, use, storage, treatment, transportation, manufacture, handling,
 production or disposal of any Hazardous Materials or any other environmental,
 health or safety matter, which affects Mortgagor or its business, operations
 or assets or any properties at which Mortgagor has transported, stored or
 disposed of any Hazardous Materials; (iii) Mortgagor has no material
 liability (contingent or otherwise) in connection with a release, spill or
 discharge, threatened or actual, of any Hazardous Materials or the
 generation, use, storage, treatment, transportation, manufacture, handling,
 production or disposal of any Hazardous Materials; and (iv) without limiting
 the generality of the foregoing, Mortgagor shall, following the determination
 by Lender that there is non-compliance, or any condition which requires any
 action by or on behalf of Mortgagor in order to avoid any non-compliance,
 with any Environmental Law, at Mortgagor’s expense, cause an independent
 environmental engineer acceptable to Lender to conduct such tests of the
 relevant site(s) as are appropriate and prepare and deliver a report setting
 forth the result of such tests, a proposed plan for remediation and an
 estimate of the costs thereof; and 

 	
  

 
	
  

 	
  

 	
  

 
	
  

 	
 (b)       Mortgagor
 agrees to defend (with counsel satisfactory to Lender), protect, indemnify
 and hold harmless Lender, each affiliate or subsidiary of Lender, and each of
 their respective officers, directors, employees, attorneys and agents (each
 an “Indemnified Party”) from and
 against any and all liabilities, obligations, losses, damages, penalties,
 actions, judgments, suits, claims, costs, expenses and disbursements of any
 kind or nature (including, without limitation, the disbursements and the
 reasonable fees of counsel for each Indemnified Party in connection with any
 investigative, administrative or judicial proceeding, whether or not the Indemnified
 Party shall be designated a party thereto), which may be imposed on, incurred
 by, or asserted against, any Indemnified Party (whether direct, indirect or
 consequential and whether based on any federal, state or local laws or
 regulations, including, without limitation, securities laws and regulations,
 Environmental Laws and commercial laws and regulations, under common law or
 in equity, or based on contract or otherwise) in any manner relating to or
 arising out of this Mortgage or any other Loan

 Instrument, or any act, event
 or transaction related or attendant thereto, the making or issuance and the
 management of the Loans or the use or intended use of the proceeds of the
 Loans; provided, however, that Mortgagor shall not have any obligation
 hereunder to any Indemnified Party with respect to matters caused by or
 resulting from the willful misconduct or gross negligence of such Indemnified
 Party, further provided, that with respect to matters asserted by the
 Mortgagor, Mortgagor shall not have any obligations hereunder to any
 Indemnified Party in the event the Mortgagor has obtained a final
 nonappealable judgment in its favor. To the extent that the undertaking to
 indemnify set forth in the preceding sentence may be unenforceable because it
 is violative of any law or public policy, Mortgagor shall satisfy such
 undertaking to the maximum extent permitted by applicable law. Any liability,
 obligation, loss, damage, penalty, cost or expense covered by this indemnity
 shall be paid to each Indemnified Party on demand, and, failing prompt
 payment, shall, together with interest thereon at the highest rate then
 applicable to Loans hereunder from the date incurred by each Indemnified
 Party until paid by Mortgagor, be added to the Mortgagor’s Liabilities and be
 secured by the Mortgaged Property. The provisions of this paragraph shall
 survive the satisfaction and payment of the other Mortgagor’s Liabilities and
 the release of this Mortgage.

ARTICLE THREE

REMEDIES

                    3.1.     Acceleration
of Maturity.
If an Event of Default shall have occurred, Lender may declare Mortgagor’s
Liabilities to be immediately due and payable, and upon such declaration
Mortgagor’s Liabilities shall immediately become and be due and payable without
further demand or notice. The foregoing shall not be in limitation of any
provision contained in any other Loan Instrument, including without limitation
any such provision pursuant to which Mortgagor’s Liabilities become immediately
due and payable without action or election by Lender. 

                    3.2.     Lender’s
Power of Enforcement. If an Event of Default shall have occurred, Lender may, either with or
without entry or taking possession as provided in this Mortgage or otherwise,
and without regard to whether or not Mortgagor’s Liabilities shall have been
accelerated, and without prejudice to the right of Lender thereafter to bring
an action of foreclosure or any other action for any default existing at the
time such earlier action was commenced or arising thereafter, proceed by any
appropriate action or proceeding: (a) to enforce satisfaction of the Guaranty
and/or any other of Mortgagor’s Liabilities or the performance of any term
hereof or any of the other Loan Instruments; (b) to foreclose this Mortgage and
to have sold, as an entirety or in separate lots or parcels, the Mortgaged
Property; and (c) to pursue any other remedy available to it. Lender may take
action either by such proceedings or by the exercise of its powers with respect
to entry or taking possession, or both, as Lender may determine. Without
limitation of the foregoing, if an Event of Default shall have occurred, as an
alternative to the right of foreclosure for the full indebtedness evidenced by
the Guaranty and the interest accrued thereon and any other Mortgagor’s
Liabilities, after acceleration thereof, Lender shall have the right to
institute partial foreclosure proceedings with respect to the portion of
Mortgagor’s Liabilities so in default, as if under a full foreclosure, and
without declaring all of Mortgagor’s Liabilities to be immediately due and
payable (such proceedings being referred to herein as “partial foreclosure”), and provided that,
if Lender has not elected to accelerate all of Mortgagor’s Liabilities and a
foreclosure sale is made because of default in payment of only a part of
Mortgagor’s Liabilities, such sale may be made subject to the continuing lien
of this Mortgage for the unmatured part of Mortgagor’s Liabilities. Any sale
pursuant to a partial foreclosure, if so made, shall not in any manner affect
the unmatured portion of Mortgagor’s Liabilities, but as to such unmatured
portion, this Mortgage and the lien thereof shall remain in full force and
effect just as though no

foreclosure sale had been made. Notwithstanding the filing of any
partial foreclosure or entry of a decree of sale therein, Lender may elect, at
any time prior to a foreclosure sale pursuant to such decree, to discontinue
such partial foreclosure and to accelerate Mortgagor’s Liabilities by reason of
any Event of Default upon which such partial foreclosure was predicated or by
reason of any other defaults, and proceed with full foreclosure proceedings.
Lender may proceed with one or more partial foreclosures without exhausting its
right to proceed with a full or partial foreclosure sale for any unmatured
portion of Mortgagor’s Liabilities, it being the purpose to permit, from time
to time a partial foreclosure sale for any matured portion of Mortgagor’s
Liabilities without exhausting the power to foreclose and to sell the Mortgaged
Property pursuant to any partial foreclosure in respect of any other portion of
Mortgagor’s Liabilities, whether matured at the time or subsequently maturing,
and without exhausting at any time the right of acceleration and the right to
proceed with a full foreclosure.

                    3.3.     Lender’s
Right to Enter and Take Possession, Operate and Apply Income.

	
  

 	
  

 
	
  

 	
 (a)     If an Event of Default shall have
 occurred, (i) Mortgagor, upon demand of Lender, shall forthwith surrender to
 Lender the actual possession of the Mortgaged Property, and to the extent
 permitted by law, Lender itself, or by such officers or agents as it may
 appoint, is hereby expressly authorized to enter and take possession of all
 or any portion of the Mortgaged Property and may exclude Mortgagor and the
 agents and employees of Mortgagor wholly therefrom and shall have joint
 access with Mortgagor to the books, papers and accounts of Mortgagor; and
 (ii) notwithstanding the provisions of any lease or other agreement to the
 contrary, Mortgagor shall pay monthly in advance to Lender, on Lender’s entry
 into possession, or to any receiver appointed to collect the rents, income
 and other benefits of the Mortgaged Property, the fair and reasonable rental
 value for the use and occupation of such part of the Mortgaged Property as
 may be in possession of Mortgagor, or any entity affiliated with or
 controlled by Mortgagor, and upon default in any such payment Mortgagor shall
 vacate and surrender possession of such part of the Mortgaged Property to
 Lender or to such receiver, and in default thereof Mortgagor may be evicted
 by summary proceedings or otherwise.

 
	
  

 	
  

 
	
  

 	
 (b)     If Mortgagor shall for any reason
 fail to surrender or deliver the Mortgaged Property or any part thereof after
 Lender’s demand, Lender may obtain a judgment or decree conferring on Lender
 the right to immediate possession or requiring Mortgagor to deliver immediate
 possession of all or part of the Mortgaged Property to Lender, to the entry
 of which judgment or decree Mortgagor hereby specifically consents. Mortgagor
 shall pay to Lender, upon 

 

21

LaSalle Bank

 demand, all costs and expenses of obtaining such judgment or decree
 and reasonable compensation to Lender, its attorneys and agents, and all such
 costs, expenses and compensation shall, until paid, be secured by the lien of
 this Mortgage.

 
	
  

 	
  

 
	
  

 	
 (c)     Upon every such entering upon or
 taking of possession, Lender, to the extent permitted by law, may hold,
 store, use, operate, manage and control the Mortgaged Property and conduct
 the business thereof, and, from time to time:

 
	
  

 	
  

 
	
  

 	
 (i)      perform such construction,
 make all necessary and proper maintenance, repairs, renewals, replacements,
 additions and improvements thereto and thereon, and purchase or otherwise
 acquire additional fixtures and personal property;

 
	
  

 	
  

 
	
  

 	
 (ii)      insure or keep the Mortgaged
 Property insured;

 
	
  

 	
  

 
	
  

 	
 (ii)      manage and operate the
 Mortgaged Property and exercise all the rights and powers of Mortgagor, on
 its behalf or otherwise, with respect to the same;

 
	
  

 	
  

 
	
  

 	
 (iv)     enter into agreements with others
 to exercise the powers herein granted Lender, all as Lender from time to time
 may determine; and Lender may collect and receive all the rents, income and
 other benefits of the Mortgaged Property, including those past due as well as
 those accruing thereafter; and shall apply the monies so received by Lender,
 in such order and manner as Lender may determine, to (1) the payment of
 amounts due under the Guaranty or pursuant to this Mortgage or to any other
 Mortgagor’s Liabilities, (2) deposits for taxes and assessments, (3) the payment
 or creation of reserves for payment of insurance, taxes, assessments and
 other proper charges or liens or encumbrances upon the Mortgaged Property or
 any part thereof, and (4) the compensation, expenses and disbursements of the
 agents, attorneys and other representatives of Lender; and

 
	
  

 	
  

 
	
  

 	
 (v)     exercise such remedies as are
 available to Lender under the Loan Instruments or at law or in equity.

 

Lender shall surrender possession of the Mortgaged Property to
Mortgagor only when all Mortgagor’s Liabilities shall have been paid in full
and all other defaults have been cured. However, the same right to take
possession shall exist if any subsequent Event of Default shall occur.

                    3.4.     Leases.
Lender is authorized to foreclose this Mortgage subject to the rights, if any,
of any or all tenants of the Mortgaged Property, even if the rights of any such
tenants are or would be subordinate to the lien of this Mortgage. Lender may elect
to foreclose the rights of some subordinate tenants while foreclosing subject
to the rights of other subordinate tenants.

                    3.5.     Purchase
by Lender. Upon any foreclosure sale, Lender may bid
for and purchase all or any portion of the Mortgaged Property and, upon
compliance with the terms of the sale, may hold, retain and possess and dispose
of such property in its own absolute right without further accountability.

                    3.6.     Application
of Foreclosure Sale Proceeds. The proceeds of any
foreclosure sale of the Mortgaged Property or any part thereof received by
Lender shall be applied by Lender to the indebtedness secured hereby in such
order and manner as Lender may elect.

                    3.7.     Application
of Indebtedness Toward Purchase Price. Upon any
foreclosure sale, Lender may apply any or all of the indebtedness and other
sums due to Lender under the Guaranty, this Mortgage or any other Loan
Instrument to the price paid by Lender at the foreclosure sale.

                    3.8.     Waiver
of Appraisement, Valuation, Stay, Extension and Redemption Laws.
Mortgagor hereby waives any and all rights of redemption. Mortgagor further
agrees, to the full extent permitted by law, that in case of an Event of Default,
neither Mortgagor nor anyone claiming through or under it will set up, claim or
seek to take advantage of any reinstatement, appraisement, valuation, stay or
extension laws now or hereafter in force, or take any other action which would
prevent or hinder the enforcement or foreclosure of this Mortgage or the
absolute sale of the Mortgaged Property or the final and absolute putting into
possession thereof, immediately after such sale, of the purchaser thereat.
Mortgagor, for itself and all who may at any time claim through or under it,
hereby waives, to the full extent that it may lawfully so do, the benefit of
all such laws, and any and all right to have the assets comprising the
Mortgaged Property marshalled upon any foreclosure of the lien hereof and agrees
that Lender or any court having jurisdiction to foreclose such lien may sell
the Mortgaged Property in part or as an entirety. 

                    3.9.     Receiver
- Lender in Possession. If an Event of Default shall
have occurred, Lender, to the extent permitted by law and without regard to the
value of the Mortgaged Property or the adequacy of the security for the
indebtedness and other sums secured hereby, shall be entitled as a matter of
right and without any additional showing or proof, at Lender’s election, to
either the appointment by the court of a receiver (without the necessity of
Lender posting a bond) to enter upon and take possession of the Mortgaged
Property and to collect all rents, income and other benefits thereof and apply
the same as the court may direct or to be placed by the court into possession
of the Mortgaged Property as mortgagee in possession with the same power herein
granted to a receiver 

23

LaSalle Bank

and with all other rights and privileges of a mortgagee in possession
under law. The right to enter and take possession of and to manage and operate
the Mortgaged Property, and to collect all rents, income and other benefits
thereof, whether by a receiver or otherwise, shall be cumulative to any other
right or remedy hereunder or afforded by law and may be exercised concurrently
therewith or independently thereof. Lender shall be liable to account only for
such rents, income and other benefits actually received by Lender, whether
received pursuant to this Section 3.9 or Section 3.3. Notwithstanding the
appointment of any receiver or other custodian, Lender shall be entitled as
pledgee to the possession and control of any cash, deposits or instruments at
the time held by, or payable or deliverable under the terms of this Mortgage to
Lender.

                    3.10.     Mortgagor
to Pay Mortgagor’s Liabilities in Event of Default; Application of Monies by
Lender.

	
  

 	
  

 
	
  

 	
 (a)     Upon occurrence of an Event of
 Default, Lender shall be entitled to sue for and to recover judgment against
 Mortgagor for Mortgagor’s Liabilities due and unpaid together with costs and
 expenses, including, without limitation, the reasonable compensation,
 expenses and disbursements of Lender’s agents, attorneys and other
 representatives, either before, after or during the pendency of any
 proceedings for the enforcement of this Mortgage; and the right of Lender to
 recover such judgment shall not be affected by any taking of possession or
 foreclosure sale hereunder, or by the exercise of any other right, power or
 remedy for the enforcement of the terms of this Mortgage, or the foreclosure
 of the lien hereof.

 
	
  

 	
  

 
	
  

 	
 (b)     In case of a foreclosure sale of all
 or any part of the Mortgaged Property and of the application of the proceeds
 of sale to the payment of Mortgagor’s Liabilities, Lender shall be entitled
 to enforce all other rights and remedies under the Loan Instruments.

 
	
  

 	
  

 
	
  

 	
 (c)     Mortgagor hereby agrees, to the
 extent permitted by law, that no recovery of any judgment by Lender under any
 of the Loan Instruments, and no attachment or levy of execution upon any of
 the Mortgaged Property or any other property of Mortgagor, shall (except as
 otherwise provided by law) in any way affect the lien of this Mortgage upon
 the Mortgaged Property or any part thereof or any lien, rights, powers or
 remedies of Lender hereunder, but such lien, rights, powers and remedies
 shall continue unimpaired as before until Mortgagor’s Liabilities are paid in
 full.

 
	
  

 	
  

 
	
  

 	
 (d)     Any monies collected or received by
 Lender under this Section 3.12 shall be applied to the payment of
 compensation, expenses and disbursements of the agents, attorneys and other

 representatives of Lender, and the balance remaining shall be applied
 to the payment of Mortgagor’s Liabilities, in such order and manner as Lender
 may elect, and any surplus, after payment of all Mortgagor’s Liabilities,
 shall be paid to Mortgagor.

 
	
  

 	
  

 

                    3.11.     Delay
or Omission. No delay or omission of Lender in the
exercise of any right, power or remedy accruing upon any Event of Default shall
exhaust or impair any such right, power or remedy, or be construed to waive any
such Event of Default or to constitute acquiescence therein. Every right, power
and remedy given to Lender may be exercised from time to time and as often as
may be deemed expedient by Lender.

                    3.12.     Waiver
of Default. No waiver of any Event of Default
hereunder shall extend to or affect any subsequent or any other Event of
Default then existing, or impair any rights, powers or remedies in respect
thereof.

                    3.13.     Remedies
Cumulative. No right, power or remedy conferred upon
or reserved to Lender by the Guaranty, this Mortgage or any other Loan
Instrument or any instrument evidencing or securing Mortgagor’s Liabilities is
exclusive of any other right, power or remedy, but each and every such right,
power and remedy shall be cumulative and concurrent and shall be in addition to
any other right, power and remedy given hereunder or under the Guaranty or any
other Loan Instrument or any instrument evidencing or securing Mortgagor’s
Liabilities, or now or hereafter existing at law, in equity or by statute.

                    4.3.     Headings.
The headings of the articles, sections, paragraphs and subdivisions of this
Mortgage are for convenience only, are not to be considered a part hereof, and

Provisions. In the event that any of the covenants,
agreements, terms or provisions contained in the Guaranty, the Notes, this
Mortgage or in any other Loan Instrument shall be invalid, illegal or

shall be in no way affected, prejudiced or disturbed thereby.

                    4.5.     Changes.
Neither this Mortgage nor any term hereof may be released, changed, waived,
discharged or terminated orally, or by any action or inaction, but only by an
instrument in writing signed by the party against which enforcement of the
release, change, waiver, discharge or termination is sought. To the extent
permitted by law, any agreement hereafter made by Mortgagor and Lender relating
to this Mortgage shall be superior to the rights of the holder of any
intervening lien or encumbrance. Any holder of a lien or encumbrance junior to
the lien of this Mortgage shall take its lien subject to the right of Lender to
amend, modify or supplement this Mortgage, the Guaranty or any of the other
Loan Instruments, to extend the maturity of Mortgagor’s Liabilities or any
portion thereof, to vary the rate of interest chargeable under the Notes and to
increase the amount of the indebtedness secured hereby, in each and every case
without obtaining the 

26

LaSalle Bank
National Association

consent of the holder of such junior lien and without the lien of this
Mortgage losing its priority over the rights of any such junior lien.

                    4.6.       Governing
Law. This Mortgage shall be construed, interpreted,
enforced and governed by and in accordance with the laws of the State of
Illinois except
that the internal laws of the State where the Mortgaged Property is located
shall govern with respect to the validity, creation, perfection, priority and
enforcement of the liens and security interests created hereby.

                    4.7.       Required
Notices. Mortgagor shall notify Lender promptly of the
occurrence of any of the following: (i) receipt of notice from any governmental
authority relating to the violation of any rule, regulation, law or ordinance,
the enforcement of which would materially and adversely affect the Mortgaged
Property; (ii) material default by any tenant in the performance of its
obligations under any lease of all or any portion of the Mortgaged Property or
receipt of any notice from any such tenant claiming that a default by landlord
in the performance of its obligations under any such lease has occurred; or
(iii) commencement of any judicial or administrative proceedings by or against
or otherwise adversely affecting Mortgagor or the Mortgaged Property.

                    4.8.       Future
Advances. This Mortgage is given to secure a guaranty
of not only existing indebtedness, but also future advances (whether such
advances are obligatory or are to be made at the option of Lender, or
otherwise) made by Lender under the Notes, to the same extent as if such future
advances were made on the date of the execution of this Mortgage. The total
amount of principal indebtedness that may be so secured may decrease or
increase from time to time, but all principal indebtedness secured hereby
shall, in no event, exceed $ 30,000,000.

                    4.9.       Release.
Upon full payment and satisfaction of Mortgagor’s Liabilities, Lender shall
issue to Mortgagor an appropriate release deed in recordable form.

                    4.10.     Attorneys’
Fees. Whenever reference is made herein to the payment
or reimbursement of attorneys’ fees, such fees shall be deemed to include
compensation to staff counsel, if any, of Lender in addition to the fees of any
other attorneys engaged by Lender. All attorneys’ fees incurred by Lender in
connection with the foreclosure of this Mortgage shall be recoverable in
foreclosure.

                    4.11.     Compliance
with Mortgage Foreclosure Law. In the event that any
provision in this Mortgage shall be inconsistent with any applicable statutory
provision governing the creation, perfection or enforcement of mortgages, such
provisions shall take precedence over the provisions of this Mortgage, but
shall not invalidate or render unenforceable any other provision of this
Mortgage that can be construed in a manner consistent with such provisions. If
any provision of this Mortgage shall grant to Lender any rights or remedies
upon default of Mortgagor which are more limited than the rights that would
otherwise be vested in Lender under applicable law in the absence of said 

27

provision, Lender shall be vested with such rights applicable law to
the full extent permitted by law. 

                    4.12.     WAIVER
OF TRIAL BY JURY. TO INDUCE LENDER TO MAKE THE LOAN,
MORTGAGOR HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY AND IRREVOCABLY WAIVES
ANY AND ALL RIGHTS WHICH MORTGAGOR MAY HAVE TO TRIAL BY JURY IN RESPECT OF ANY
LEGAL PROCEEDINGS IN WHICH MORTGAGOR AND LENDER ARE ADVERSE PARTIES, IN
CONNECTION WITH THE NOTES, THIS MORTGAGE OR ANY OF THE OTHER LOAN INSTRUMENTS.

                    4.13.     CONSENT
TO JURISDICTION, SERVICE OF PROCESS. TO INDUCE LENDER
TO MAKE THE LOAN, MORTGAGOR HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY AND
IRREVOCABLY AGREES THAT ALL ACTIONS ARISING DIRECTLY OR INDIRECTLY AS A RESULT
OF THE NOTES, THIS MORTGAGE OR ANY OF THE OTHER LOAN INSTRUMENTS SHALL BE
INSTITUTED AND LITIGATED ONLY IN COURTS HAVING SITUS IN THE CITY OF CHICAGO,
ILLINOIS, AND MORTGAGOR HEREBY CONSENTS TO THE EXCLUSIVE JURISDICTION AND VENUE
OF ANY STATE OR FEDERAL COURT LOCATED AND HAVING SITUS IN SAID CITY OF CHICAGO,
AND WAIVES ANY OBJECTION BASED ON FORUM NON CONVENIENS. MORTGAGOR HEREBY
KNOWINGLY, VOLUNTARILY, INTENTIONALLY AND IRREVOCABLY WAIVES PERSONAL SERVICE
OF ANY AND ALL PROCESS, AND CONSENTS THAT, AT LENDER’S OPTION, ALL SUCH SERVICE
OF PROCESS MAY BE MADE BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED, DIRECTED TO
MORTGAGOR AT THE ADDRESS FOR MORTGAGOR INDICATED IN SECTION 4.2 ABOVE.

                    IN
WITNESS WHEREOF, Mortgagor has caused this instrument to be executed by its
duly authorized officers as of the day and year first above written.
