segregate such assets and hold them as a separate trust fund. The Issuer at any
time may require a Paying Agent to distribute all assets held by it to the
Trustee and account for any assets disbursed and the Trustee may at any time
during the continuance of any payment Default or payment Event of Default, upon
written request to a Paying Agent, require such Paying Agent to distribute all
assets held by it to the Trustee and to account for any assets distributed. Upon
distribution to the Trustee of all assets that shall have been delivered by the
Issuer to the Paying Agent, the Paying Agent shall have no further liability for
such assets.

2.5  HOLDER LISTS.

     The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders. If the Trustee is not the Registrar, the Issuer shall furnish to the
Trustee on or before each Interest Payment Date and at such other times as the
Trustee may request in writing a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Holders, which list
may be conclusively relied upon by the Trustee.

2.6  TRANSFER AND EXCHANGE.

     (a) Subject to the provisions of Sections 2.15 and 2.16, when Securities
are presented to the Registrar or a co-Registrar with a request to register the
transfer of such Securities or to exchange such Securities for an equal
principal amount of Securities of other authorized denominations, the Registrar
or co-Registrar shall register the transfer or make the exchange as requested if
its requirements for such transaction are met; provided, however, that the
Securities surrendered for registration of transfer or exchange shall be duly
endorsed or accompanied by a written instrument of transfer in form satisfactory
to the Issuer and the Registrar or co-Registrar, duly executed by the Holder
thereof or his attorney duly authorized in writing. To permit registrations of
transfers and exchanges, the Issuer shall execute and the Trustee shall
authenticate Securities at the Registrar's or co-Registrar's request. No service
charge shall be made for any registration of transfer or exchange, but the
Issuer may require payment of a sum sufficient to cover any transfer tax or
similar governmental charge payable in connection therewith (other than any such
transfer taxes or similar governmental charge payable upon exchanges or
transfers pursuant to Section 2.2, 2.10, 3.6, 3.7, 4.16, 4.17, 4.20, 4.21 or
9.6). The


                                       33

<PAGE>

Registrar or co-Registrar shall not be required to register the transfer of or
exchange of any Security (i) during a period beginning at the opening of
business 15 days before the mailing of a notice of redemption of Securities and
ending at the close of business on the day of such mailing, (ii) selected for
redemption in whole or in part pursuant to Article III, except the unredeemed
portion of any Security being redeemed in part, and (iii) during an Offer to
Purchase made pursuant to Section 4.16, 4.17, 4.20 or 4.21 if such Security is
tendered pursuant to such Offer to Purchase and not withdrawn. A Global Security
may be transferred, in whole but not in part, in the manner provided in this
Section 2.6(a), only to a nominee of the Depository for such Global Security, or
to the Depository, or a successor Depository for such Global Security selected
or approved by the Issuer, or to a nominee of such successor Depository.

     (b) If at any time the Depository for the Global Security or Securities
notifies the Issuer that it is unwilling or unable to continue as Depository for
such Global Security or Securities or the Issuer become aware that the
Depository has ceased to be a clearing agency registered under the Exchange Act,
the Issuer shall appoint a successor Depository with respect to such Global
Security or Securities. If a successor Depository for such Global Security or
Securities has not been appointed within 90 days after the Issuer receives such
notice or becomes aware of such ineligibility, the Issuer shall execute, and the
Trustee, upon receipt of an Officers' Certificate for the authentication and
delivery of Physical Securities, shall authenticate and deliver, Physical
Securities, in an aggregate principal amount at maturity equal to the principal
amount at maturity of the Global Security representing such Securities, in
exchange for such Global Security. The Issuer shall reimburse the Registrar, the
Depository and the Trustee for expenses they incur in documenting such exchanges
and issuances of Securities.

     The Issuer may at any time and in its sole discretion determine that the
Securities shall no longer be represented by such Global Security or Securities.
In such event the Issuer shall execute, and the Trustee, upon receipt of a
written order for the authentication and delivery of Physical Securities in
exchange in whole or in part for such Global Security or Securities accompanied
by an Officers' Certificate, shall authenticate and deliver Physical Securities
in an aggregate principal amount equal to the principal amount of such Global
Security or Securities in exchange for such Global Security or Securities.

     In any exchange provided for in any of the preceding two paragraphs, the
Issuer shall execute and the Trustee shall authenticate and deliver Physical
Securities in authorized denominations. Upon the exchange of a Global Security
for Physical Securities, such Global Security shall be cancelled by the Trustee.
Physical Securities issued in exchange for a Global Security pursuant to this
Section 2.6(b) shall be registered in such names and in such authorized
denominations as the Depository for such Global Security, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Securities to the Persons
in whose names such Securities are so registered in the manner and to the
addresses specified by the Depository.

     None of the Issuer, the Trustee, any Paying Agent or the Registrar shall
have any responsibility or liability for any aspect of the records relating to
or payments made on account of beneficial ownership interests in a Global
Security or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

2.7  REPLACEMENT SECURITIES.

     If a mutilated Security is surrendered to the Trustee or if the Holder of a
Security claims that the Security has been lost, destroyed or wrongfully taken,
the Issuer shall issue and the Trustee shall authenticate a replacement Security
if the Trustee's and Issuer's requirements are met. If required by the Trustee
or the Issuer, such Holder must provide an indemnity bond or other indemnity,
sufficient in the judgment of both the Issuer and the Trustee, to protect the
Issuer, the Trustee or any Agent from any loss which any of them may suffer if a
Security is replaced. The Issuer may charge such Holder for its reasonable
out-of-pocket expenses in replacing a Security pursuant to this Section 2.7,
including reasonable fees and expenses of counsel.

     Every replacement Security is an additional obligation of the Issuer.

2.8  OUTSTANDING SECURITIES.

     Securities outstanding at any time are all the Securities that have been
authenticated by the Trustee except those cancelled by it, those delivered to it
for cancellation and those described in this Section as not outstanding. A
Security does not cease to be outstanding because either of the Issuer, any
Subsidiary Guarantor or any of their respective Subsidiaries or Affiliates holds
the Security.

     If a Security is replaced pursuant to Section 2.7 (other than a mutilated
Security surrendered for replacement), it ceases to be outstanding unless the
Trustee receives proof satisfactory to it that the replaced Security is held by
a bona fide purchaser or a protected purchaser. A mutilated Security ceases to
be outstanding upon surrender of such Security and replacement thereof pursuant
to Section 2.7. If the principal amount of any Security is considered paid under
Section 4.1, it ceases to be outstanding and interest ceases to accrue.

     If on a Redemption Date or the Maturity Date the Paying Agent (other than
either of the Issuer or a Subsidiary) holds U.S. Legal Tender sufficient to pay
all of the principal, premium, if any, and interest due on the Securities
payable on that date, then on and after that date such Securities cease to be
outstanding and interest on them ceases to accrue.

2.9  TREASURY SECURITIES.

     In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, waiver or consent, Securities owned
by the Issuer, any of its Subsidiaries or any of their respective Affiliates
shall be disregarded, except that, for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Securities that a Responsible Officer of the Trustee has Actual Knowledge
are so owned shall be disregarded.

2.10 TEMPORARY SECURITIES.

     Until definitive Securities are ready for delivery, the Issuer may prepare
and the Trustee shall authenticate temporary Securities. Temporary Securities
shall be substantially in the form of definitive Securities but may have
variations that the Issuer considers appropriate for


                                       35

<PAGE>

temporary Securities, as evidenced by execution of such temporary Securities by
the Issuer. Without unreasonable delay, the Issuer shall prepare and the Trustee
shall authenticate definitive Securities in exchange for temporary Securities.
Until such exchange, temporary Securities shall be entitled to the same rights,
benefits and privileges as definitive Securities. Notwithstanding the foregoing,
so long as the Securities are represented by a Global Security, such Global
Security may be in typewritten form.

2.11 CANCELLATION.

     The Issuer at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for registration of transfer, exchange or
payment. The Trustee, or at the direction of the Trustee, the Registrar or the
Paying Agent (other than either of the Issuer or a Subsidiary), and no one else,
shall cancel and shall dispose of all Securities surrendered for registration of
transfer, exchange, payment or cancellation. Subject to Section 2.7, the Issuer
may not issue new Securities to replace Securities that it has paid or delivered
to the Trustee for cancellation. If the Issuer or any Subsidiary Guarantor shall
acquire any of the Securities, such acquisition shall not operate as a
redemption or satisfaction of the Indebtedness represented by such Securities
unless and until the same are surrendered to the Trustee for cancellation
pursuant to this Section 2.11.

2.12 DEFAULTED INTEREST.

     If the Issuer defaults in a payment of interest on the Securities, it
shall, unless the Trustee fixes another record date pursuant to Section 6.10,
pay the defaulted interest, plus (to the extent lawful) any interest payable on
the defaulted interest, in any lawful manner. The Issuer may pay the defaulted
interest to the Persons who are Holders on a subsequent special record date,
which date shall be the fifteenth day next preceding the date fixed by the
Issuer for the payment of defaulted interest or the next succeeding Business Day
if such date is not a Business Day. At least 15 days before any such subsequent
special record date, the Issuer shall mail to each Holder, with a copy to the
Trustee, a notice that states the subsequent special record date, the payment
date and the amount of defaulted interest, and interest payable on such
defaulted interest, if any, to be paid.

2.13 CUSIP AND ISIN NUMBERS.

     The Issuer in issuing the Securities may use "CUSIP" and "ISIN" numbers,
and if so, the Trustee shall use the CUSIP and ISIN numbers in notices of
redemption or exchange as a convenience to Holders; provided, however, that any
such notice may state that no representation is made as to the correctness or
accuracy of the CUSIP and ISIN numbers printed in the notice or on the
Securities, and that reliance may be placed only on the other identification
numbers printed on the Securities and that any such redemption or exchange shall
not be affected by any defect or omission of such CUSIP and ISIN numbers. The
Issuer shall promptly notify the Trustee of any change in CUSIP or ISIN number.

2.14 RESTRICTIVE LEGENDS.

     Unless and until a Security is exchanged for an Exchange Note or sold in
connection with an effective registration statement under the Securities Act
pursuant to the Registration Rights


                                       36

     Global Securities in an amount equal to the principal amount of the U.S.
     Physical Securities or the U.S. Global Securities, as the case may be, to
     be transferred, and the Trustee shall cancel the U.S. Physical Security, if
     any, so transferred or decrease the amount of the U.S. Global Security.

     (f) Private Placement Legend. Upon the registration of transfer, exchange
or replacement of Securities not bearing the Private Placement Legend, the
Registrar shall deliver Securities that do not bear the Private Placement
Legend. Upon the registration of transfer, exchange or replacement of Securities
bearing the Private Placement Legend, the Registrar shall deliver only
Securities that bear the Private Placement Legend unless (i) the transferee
certifies that it is not an Affiliate of the Issuer and the requested transfer
is after the second anniversary of the later of (a) the date on which such
Securities are originally issued and (b) the last date on which the Issuer or an
Affiliate of the Issuer was the owner of such Securities (or any predecessor
Securities) or such shorter period of time as permitted by Rule 144(k) under the
Securities Act or any successor provision thereunder or (ii) the circumstance
contemplated by clause (d) or (e)(ii) of this Section 2.16 exists or (iii) there
is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to
the Issuer and the Trustee to the effect that neither such legend nor the
related restrictions on transfer are required in order to maintain compliance
with the provisions of the Securities Act.

     (g) General. By its acceptance of any Security bearing the Private
Placement Legend, each Holder of such Security acknowledges the restrictions on
transfer of such Security set forth in this Indenture and in the Private
Placement Legend and agrees that it shall transfer such Security only as
provided in this Indenture.

     The Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 2.15 or this Section 2.16 in
accordance with its customary procedures. The Issuer shall have the right to
inspect and make copies of all such letters, notices or other written
communications at any reasonable time upon the giving of reasonable written
notice to the Registrar.

                          REDEMPTION; OFFER TO PURCHASE

3.1  NOTICES TO TRUSTEE.

     If the Issuer elects to redeem Securities pursuant to Section 5 or 6 of the
Securities, it shall notify the Trustee in writing of the Redemption Date, the
Redemption Price and the principal amount of the applicable Securities to be
redeemed. The Issuer shall give such notice of redemption to the Paying Agent
and Trustee at least 30 days but not more than 60 days before the Redemption
Date, together with an Officers' Certificate stating that such redemption shall
comply with the conditions contained herein and provide the information
specified in Section 3.3.

3.2  SELECTION OF SECURITIES TO BE REDEEMED.

     In the event that less than all of the Securities are to be redeemed at any
time, selection of such Securities for redemption shall be made (subject to the
procedures of the Depository) by the Trustee in compliance with the requirements
of the principal national securities exchange, if any, on which such Securities
are listed or, if such Securities are not then listed on a national securities
exchange, by lot or by such method as the Trustee in its sole discretion shall
deem fair and appropriate; provided, however, that no Securities of a principal
amount of $2,000 or less shall be redeemed in part.

3.3  NOTICE OF REDEMPTION.

     At least 30 days but not more than 60 days before a Redemption Date, the
Issuer shall mail a notice of redemption by first class mail, postage prepaid,
to each Holder whose Securities are to be redeemed at its registered address. At
the Issuer's request at least 30 days before a Redemption Date (unless a shorter
period shall be acceptable to the Trustee), the Trustee shall give the notice of
redemption in the Issuer's name and at the Issuer's expense. Each notice of
redemption shall identify the Securities to be redeemed and shall state:

     (a) the Redemption Date;

     (b) the Redemption Price and the amount of accrued interest, if any, to be
paid;

     (c) the name and address of the Paying Agent;

     (d) that Securities called for redemption must be surrendered to the Paying
Agent to collect the Redemption Price plus accrued interest, if any;

     (e) that, unless the Issuer defaults in making the redemption payment,
interest on Securities called for redemption ceases to accrue on and after the
Redemption Date, and the only remaining right of the Holders of such Securities
is to receive payment of the Redemption Price and accrued interest, if any, upon
surrender to the Paying Agent of the Securities redeemed;


                                       43

<PAGE>

     (f) if any Security is being redeemed in part, the portion of the principal
amount of such Security to be redeemed and that, after the Redemption Date, and
upon surrender of such Security, a new Security or Securities in aggregate
principal amount equal to the unredeemed portion thereof shall be issued;

     (g) if fewer than all the Securities are to be redeemed, the identification
of the particular Securities (or portion thereof) to be redeemed, as well as the
aggregate principal amount of Securities to be redeemed and the aggregate
principal amount of Securities to be outstanding after such partial redemption;

     (h) the section of the Securities pursuant to which the Securities are to
be redeemed; and

     (i) the CUSIP or ISIN number, if any, printed on the Securities being
redeemed and a statement that no representation is made as to the correctness or
accuracy of the CUSIP or ISIN number, if any, listed in such notice or printed
on the Securities.

     In addition, if such redemption is subject to satisfaction of one or more
conditions precedent, such notice of redemption shall describe each such
condition and shall state that such redemption may not occur and such notice may
be rescinded in the event that any or all such conditions shall not have been
satisfied by the Redemption Date as stated in such notice.

     The notice, if mailed in a manner herein provided, shall be conclusively
presumed to have been given, whether or not the Holder receives such notice. In
any case, failure to give such notice by mail or any defect in the notice to the
Holder of any Security designated for redemption in whole or in part shall not
affect the validity of the proceedings for the redemption of any other Security.

3.4  EFFECT OF NOTICE OF REDEMPTION.

     Once notice of redemption is mailed in accordance with Section 3.3,
Securities called for redemption become due and payable on the Redemption Date
and at the Redemption Price plus accrued interest, if any, subject to the
satisfaction of any conditions precedent provided in such notice. Upon surrender
to the Trustee or Paying Agent, such Securities called for redemption shall be
paid at the Redemption Price (which shall include accrued interest thereon to
the Redemption Date), but installments of interest, the maturity of which is on
or prior to the Redemption Date, shall be payable to Holders of record at the
close of business on the relevant Record Dates.

3.5  DEPOSIT OF REDEMPTION PRICE.

     On or before 11:00 a.m. New York time on the Redemption Date, the Issuer
shall deposit with the Paying Agent U.S. Legal Tender in immediately available
funds sufficient to pay the Redemption Price plus accrued interest, if any, of
all Securities to be redeemed on that date.

     If the Issuer complies with the preceding paragraph, then, unless the
Issuer defaults in the payment of such Redemption Price plus accrued interest,
if any, interest on the Securities to be


                                       44

<PAGE>

redeemed shall cease to accrue on and after the applicable Redemption Date,
whether or not such Securities are presented for payment.

3.6  SECURITIES REDEEMED IN PART.

     Upon surrender of a Security that is to be redeemed in part only, the
Trustee shall upon written instruction from the Issuer accompanied by an
Officers' Certificate authenticate for the Holder a new Security or Securities
in a principal amount equal to the unredeemed portion of the Security
surrendered.

3.7  OFFER TO PURCHASE.

     In the event that, pursuant to Section 4.16, 4.17, 4.20 or 4.21, the Issuer
shall be required to commence an offer to purchase Securities from the Holders
in accordance with the procedures specified in the following provisions of this
Section 3.7 (an "Offer to Purchase"), the Issuer shall commence an Offer to
Purchase by mailing a notice to the Trustee, each Holder and, in the event of a
Special Offer to Purchase, the Escrow Agent stating:

pro rata basis;

     (2) the purchase price and the date of purchase, which shall be a Business

Offer to Purchase, in either which case the date of purchase shall be a Business
Day no later than five Business Days from such mailing date) (the "Payment
Date");

     (3) that any Security not tendered shall continue to accrue interest
pursuant to its terms;

     (4) that, unless the Issuer defaults in the payment of the purchase price,
any Security accepted for payment pursuant to the Offer to Purchase shall cease
to accrue interest on and after the Payment Date;

     (5) that Holders electing to have a Security purchased pursuant to the
Offer to Purchase shall be required to surrender the Security, together with the
form entitled "Option of the Holder to Elect Purchase" on the reverse side of
the Security completed, to the Paying Agent at the address specified in the
notice prior to the close of business on the Business Day immediately preceding
the Payment Date;

     (6) that Holders shall be entitled to withdraw their election if the Paying
Agent receives, not later than the close of business on the third Business Day
immediately preceding the Payment Date, a telegram, facsimile transmission or
letter setting forth the name of such Holder, the principal amount of Securities
delivered for purchase and a statement that such Holder is withdrawing his
election to have such Securities purchased; and

     (7) that Holders whose Securities are being purchased only in part shall be
issued new Securities equal in principal amount to the unpurchased portion of
the Securities


                                       45

<PAGE>

surrendered; provided that each Security purchased and each new Security issued
shall be in a principal amount of $2,000 or integral multiples of $1,000 in
excess thereof.

     On the Payment Date, the Issuer shall (a) accept for payment on a pro rata
basis Securities and Parity Lien Indebtedness, if applicable (other than with
respect to a Special Offer to Purchase, in which case only Securities shall be
purchased) or portions thereof tendered pursuant to an Offer to Purchase; (b)
deposit, or cause to be deposited, with the Paying Agent money sufficient to pay
the purchase price of all Securities and with the Parity Lien Representative
money sufficient to pay all Parity Lien Indebtedness, if applicable, or portions
thereof so accepted; and (c) deliver, or cause to be delivered, to the Trustee
all Securities or portions thereof so accepted together with an Officers'
Certificate specifying the Securities or portions thereof accepted for payment
by the Issuer. The Paying Agent shall promptly mail to the Holders so accepted
payment in an amount equal to the purchase price, and the Trustee shall promptly
authenticate and mail to such Holders a new Security equal in principal amount
to any unpurchased portion of the Security surrendered; provided that each
Security purchased and each new Security issued shall be in a principal amount
of $2,000 or integral multiples of $1,000 in excess thereof. The Issuer shall
publicly announce the results of an Offer to Purchase as soon as practicable
after the Payment Date. The Trustee shall act as the Paying Agent for an Offer
to Purchase. The Issuer shall comply with Rule 14e-l under the Exchange Act and
any other securities laws and regulations thereunder, to the extent such laws
and regulations are applicable, in the event that the Issuer is required to
repurchase Securities pursuant to an Offer to Purchase. To the extent that the
provisions of any securities laws or regulations conflict with the provisions of
this Indenture relating to an Offer to Purchase, the Issuer shall comply with
the applicable securities laws and regulations and shall not be deemed to have
breached its obligations under such provisions of this Indenture by virtue of
such conflict.

Tender in immediately available funds designated for and sufficient to pay the
installment. If the Issuer or any Subsidiary acts as Paying Agent, an
installment of principal, premium, if any, or interest shall be considered paid

     The Issuer may also from time to time designate one or more other offices
or agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations. The Issuer
shall give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or agency.

     The Issuer hereby initially designates the Trustee at its Corporate Trust

4.3, the Issuer, in its sole discretion, may divide and classify, and from time
to time may classify, re-divide or reclassify, such Restricted Payment if it
would have been permitted at the time such Restricted Payment was made and at
the time of such reclassification.

     Not later than the date of making any Restricted Payment, the Issuer shall
deliver to the Trustee an Officers' Certificate stating that such Restricted
Payment complies with this Indenture and setting forth in reasonable detail the
basis upon which the required calculations were computed, which calculations may

     (a) The Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, Incur any Indebtedness (other than the Initial Notes, the Note

however, that the Issuer may Incur Indebtedness (including, without limitation,
Acquired Indebtedness) and any Subsidiary Guarantor may Incur Indebtedness
(including, without limitation, Acquired Indebtedness) if, after giving effect
to the Incurrence of such Indebtedness and the receipt and application of the

     Subsidiary; provided that (x) any event which results in any such
     Restricted Subsidiary ceasing to be a Restricted Subsidiary or any
     subsequent transfer of such Indebtedness (other than to the Issuer or
     another Restricted Subsidiary) shall be deemed, in each case, to constitute
     an Incurrence of such Indebtedness not permitted by this clause (2) and (y)
     if the Issuer or any Subsidiary Guarantor is the obligor on such
     Indebtedness, such Indebtedness must be expressly subordinated in right of
     payment to the Securities, in the case of the Issuer, or the Note
     Guarantee, in the case of a Subsidiary Guarantor;

          (3) Indebtedness issued in exchange for, or the net proceeds of which
     are used to refinance or refund, then outstanding Indebtedness (other than
     Indebtedness outstanding under clause (1), (2) or (10) of this Section
     4.4(a) and under this clause (3)) in an amount not to exceed the amount so

     expenses); provided that (a) Indebtedness the proceeds of which are used to
     refinance or refund the Securities or Indebtedness that is pari passu with,
     or subordinated in right of payment to, the Securities or a Note Guarantee
     shall only be permitted under this clause (3) if (x) in case the Securities
     are refinanced in part or the Indebtedness to be refinanced is pari passu
     with the Securities or a Note Guarantee, such new Indebtedness, by its
     terms or by the terms of any agreement or instrument pursuant to which such
     new Indebtedness is outstanding, is expressly made pari passu with, or
     subordinate in right of payment to, the remaining Securities or the Note
     Guarantee, or (y) in case the Indebtedness to be refinanced is subordinated
     in right of payment to the Securities or a Note Guarantee, such new
     Indebtedness, by its terms or by the terms of any agreement or instrument
     pursuant to which such new Indebtedness is issued or remains outstanding,
     is expressly made subordinate in right of payment to the Securities or the
     Note Guarantee at least to the extent that the Indebtedness to be
     refinanced is subordinated to the Securities or the Note Guarantee, (b)
     such new Indebtedness, determined as of the date of Incurrence of such new
     Indebtedness, does not mature prior to the Stated Maturity of the
     Indebtedness to be refinanced or refunded, and the Average Life of such new
     Indebtedness is at least equal to the remaining Average Life of the

     (b) The accrual of interest or dividends, the accretion or amortization of

complies with this covenant.

     (e) The Obligors shall not Incur any Indebtedness if such Indebtedness is
subordinate in right of payment to any other Indebtedness unless such
Indebtedness is also subordinate in right of payment to the Securities (in the
case of the Issuer) or the Note Guarantees (in the case of any Subsidiary
Guarantor), in each case, to the same extent.

corporate existence and the corporate, partnership or other existence of each of
its Restricted Subsidiaries in accordance with the respective organizational
documents of each such Restricted Subsidiary and the rights (charter and
statutory) and material franchises of the Issuer and each of its Restricted
Subsidiaries; provided, however, that neither the Issuer nor any Restricted
Subsidiary shall be required to preserve any such right or franchise or in the

cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, (i) the applicability or validity is being contested in good faith by

material respect to the Holders.

so that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that, subject to
Section 4.19 nothing in this Section 4.7 shall prevent the Issuer or any of its
Restricted Subsidiaries from discontinuing the use, operation or maintenance of
any of such properties, or disposing of any of them, if such discontinuance or
disposal is, in the judgment of the Board of Directors of the Issuer or any such
Restricted Subsidiary desirable in the conduct of the business of the Issuer or
any such Restricted Subsidiary, and if such discontinuance or disposal is not
adverse in any material respect to the


                                       53

Subsidiaries elect to change the manner in which it fixes its fiscal year end.

     (b) The Issuer shall deliver promptly to the Trustee, in the event that any
Officer becomes aware of any Default or Event of Default in the performance of

     Equally and Ratably secured by all Liens, guarantees, supporting
     obligations and loss sharing rights at any time granted by the Issuer or

outstanding, at a purchase price equal to 101% of their principal amount, plus
accrued interest (if any) to, but not including, the Payment Date.

     (b) Notwithstanding the provisions of clause (a) above, the Issuer shall
not be required to make an Offer to Purchase upon the occurrence of a Change of
Control if a third party makes an offer to purchase the Securities in the
manner, at the times and price and otherwise in compliance with the requirements
of this Indenture applicable to an Offer to Purchase for a Change of Control and
purchases all Securities validly tendered and not withdrawn in such Offer to
Purchase.

     (c) Any Offer to Purchase required pursuant to this Section 4.16, may be
made in advance of a Change of Control, and conditioned upon the occurrence of
such Change of Control, if a definitive agreement is in place for the Change of
Control at the time of making the Offer to Purchase. Securities repurchased by
the Issuer pursuant to an Offer to Purchase shall have the status of Securities
issued but not outstanding or shall be retired and canceled, at the option of
the Issuer. Securities purchased by a third party pursuant to clause (b) above
shall have the status of Securities issued and outstanding.

4.17 LIMITATION ON ASSET SALES.

     (a) The Issuer shall not, and shall not permit any Restricted Subsidiary
to, consummate any Asset Sale, unless (1) the consideration received by the
Issuer or such Restricted Subsidiary is at least equal to the fair market value
of the assets sold or disposed of, (2) at least 75% of the consideration
received consists of (a) cash or Temporary Cash Investments, (b) the assumption
of unsubordinated Indebtedness of the Issuer or any Subsidiary Guarantor or
Indebtedness of any other Restricted Subsidiary (in each case, other than
Indebtedness owed to the Issuer or any Affiliate of the Issuer) by a transferee,
provided that the Issuer, such Subsidiary Guarantor or such other Restricted
Subsidiary is irrevocably and unconditionally released from all liability under
such Indebtedness, or (c) Replacement Assets, and (3) in the event of a
Collateral Asset Sale, the Net Cash Proceeds corresponding to the Collateral
sold shall be paid directly to the Joint Collateral Agent for deposit into the
Collateral Account which shall become part of the Collateral and be subject to
the Note Lien in favor of the Holders and, to the extent applicable, the Parity
Lien in favor of the holders of any Parity Lien Indebtedness.

     For the purposes of this provision, any securities, notes or other
obligations received by the Issuer or any of its Restricted Subsidiaries from
the transferee that are converted by the Issuer or any of its Restricted
Subsidiaries into cash or Temporary Cash Investments within 180 days of their
receipt by the Issuer or any of its Restricted Subsidiaries shall be deemed to
be cash, but only to the extent of the cash or Temporary Cash Investments
received.

     (b) The Issuer shall, or shall cause the relevant Restricted Subsidiary to,
within twelve months after the date of receipt of any Net Cash Proceeds from an
Asset Sale,

          (i) solely in the case of Net Cash Proceeds from any Asset Sale other
     than a Collateral Asset Sale, apply an amount equal to such Net Cash
     Proceeds to repay or reduce outstanding (1) Securities, Parity Lien
     Indebtedness or other Indebtedness of the Issuer that is pari passu in
     right of payment with the Securities, provided that any repayment of the
     Securities or Parity Lien Indebtedness shall be applied as set forth in
     clause (c) of this Section 4.17, (2) Indebtedness of any Subsidiary
     Guarantor that is pari passu in right of payment with the relevant Note
     Guarantee or (3) Indebtedness of any other Restricted Subsidiary, or

          (ii) invest an equal amount, or the amount not so applied pursuant to
     clause (a)(1) above (or enter into a definitive agreement committing to so
     invest within 12 months after the date of such agreement), in Replacement
     Assets.

     The amount of such excess Net Cash Proceeds required to be applied (or to
be committed to be applied) during such 12-month period as set forth in the
preceding sentence and not applied as so required by the end of such period
shall constitute "Excess Proceeds."

     (c) If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
Section 4.17 totals at least $15,000,000, the Issuer shall commence, not later
than the last Business Day of such month, and consummate an Offer to Purchase
from the Holders and, if required by the terms of any


                                       61

<PAGE>

Parity Lien Indebtedness, from the holders of such Parity Lien Indebtedness, on
a pro rata basis an aggregate principal amount of Securities (and Parity Lien
Indebtedness) equal to the Excess Proceeds on such date, at a purchase price
equal to 100% of their principal amount, plus, in each case, accrued interest
(if any) to, but not including, the Payment Date. To the extent that any Excess
Proceeds remain after consummation of an Offer to Purchase pursuant to this
Section 4.17, the Issuer may use those Excess Proceeds for any purpose not
otherwise prohibited by this Indenture and the amount of Excess Proceeds shall
be reset to zero.

4.18 LIMITATION ON BUSINESS ACTIVITIES.

     The Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, engage in any business other than a Permitted Business.

4.19 LIMITATION ON IMPAIRMENT OF SECURITY INTEREST.

     Neither the Issuer nor any of its Subsidiaries shall take or omit to take
any action which action or omission could reasonably be expected to have the
result of adversely affecting or impairing the Note Liens, other than as
expressly contemplated by this Indenture or the Security Documents; provided,
however, that the taking of any action with respect to the Collateral that is
required by the terms of this Indenture shall be deemed not to impair such
security interest.

4.20 EVENTS OF LOSS.

     (a) In the event of an Event of Loss with respect to any Collateral, the
Issuer shall apply the Net Loss Proceeds from such Event of Loss, at its option,
to (1) the rebuilding, repair, replacement or construction of improvements to
the affected property within two years after receipt of such Net Loss Proceeds,
(2) the acquisition of or investment in Replacement Assets within one year after
receipt of such Net Loss Proceeds or (3) a redemption of the Securities and any
Parity Lien Indebtedness on a pro rata basis pursuant to an Offer to Purchase on
the terms described in clause (b) below. Pending the final application of any
Net Loss Proceeds, the Issuer shall deposit such Net Loss Proceeds in the
Collateral Account.

     (b) Any Net Loss Proceeds from an Event of Loss that are not applied or
invested as provided in clause (a) above shall be deemed to constitute "Excess
Loss Proceeds." If, as of the first day of any calendar month, the aggregate
amount of Excess Loss Proceeds not theretofore subject to an Offer to Purchase
pursuant to this Section 4.20 totals at least $15,000,000, the Issuer shall
commence, not later than the last Business Day of such month, and consummate an
Offer to Purchase from the Holders and holders of any Parity Lien Indebtedness
outstanding at such time, on a pro rata basis an aggregate principal amount of
Securities and Parity Lien Indebtedness outstanding at such time, equal to the
Excess Loss Proceeds on such date, at a purchase price equal to 100% of the
principal amount thereof plus accrued interest thereon (if any) to, but not
including, the Payment Date. Any Offer to Purchase commenced pursuant to this
Section 4.20 shall be referred to as an "Event of Loss Offer to Purchase." To
the extent that any Excess Loss Proceeds remain after consummation of an Event
of Loss Offer to Purchase, the Issuer may use those Excess Loss Proceeds for any
purpose not otherwise prohibited by this Indenture and the amount of Excess Loss
Proceeds shall be reset to zero.

Person to merge with or into it unless:

          (i) it shall be the continuing Person, or the Person (if other than
     it) formed by such consolidation or into which it is merged or that
     acquired or leased such property and assets (the "Surviving Person") shall

     Rights Agreement and the Security Documents;

          (ii) each of the conditions specified in clause (c) below is

<PAGE>

     amendment to its Note Guarantee confirmed that its Note Guarantee shall
     apply to the obligations of the Issuer or the Surviving Person in
     accordance with the Securities and this Indenture.

     (b) No Subsidiary Guarantor shall consolidate with or merge with or into
any Person or permit any Person to merge with or into it unless:

          (i) it shall be the continuing Person, or the Person (if other than

any other Subsidiary Guarantor, so long as the Issuer or such Subsidiary
Guarantor survives such consolidation or merger or (y) a sale or other
disposition of all of the assets of a Subsidiary Guarantor, by way of merger,
consolidation or otherwise, if the Issuer or a Restricted Subsidiary applies the
Net Cash Proceeds of that sale or other disposition in accordance with Section

     Event of Default shall have occurred and be continuing;

          (ii) immediately after giving effect to such transaction on a pro
     forma basis the Issuer (or the Surviving Person, if applicable) (x) could
     Incur at least $1.00 of Indebtedness under the first sentence of clause (a)
     of Section 4.4 or (y) would, together with its Restricted Subsidiaries,
     have a greater Fixed Charge Coverage Ratio immediately after that
     transaction (after giving pro forma effect thereto as if that transaction
     had occurred at the beginning of the applicable four-quarter period) than
     the Fixed Charge Coverage Ratio of the Issuer and its Restricted
     Subsidiaries immediately prior to that transaction;

          (iii) the Issuer or such Subsidiary Guarantor or the relevant
     surviving entity, as applicable, shall cause such amendments, supplements
     or other instruments to be filed, executed and/or recorded in such

     by or sold, conveyed, transferred, leased or otherwise disposed of to such
     Person, together with such financing statements as may be required to
     perfect any security interests in such Collateral which may be perfected by
     the filing of a financing statement under the UCC of the relevant states;

          (iv) the Collateral owned by or sold, conveyed, transferred, leased or
     otherwise disposed of to the Issuer or such Subsidiary Guarantor or the
     relevant surviving entity, as applicable, shall (a) continue to constitute
     Collateral under this Indenture and the Security Documents, and (b) be
     subject to the Note Liens, as applicable, in favor of the Joint Collateral
     Agent for the benefit of the Trustee and the Holders, subject to Liens in

     and the Parity Lien Representative;

          (v) the assets of the Person which is merged or consolidated with or
     into the relevant surviving entity, to the extent that they are assets of
     the types which would constitute Collateral under this Indenture and the
     Security Documents, shall be treated as after acquired property and such
     surviving entity shall take such action as may be reasonably necessary to
     cause such assets to be made subject to the Note Liens and, if applicable,
     the Parity Liens and to perfect such Liens in respect of such assets, in
     each case, in the manner and to the extent required under the Security
     Documents; and

          (vi) the Issuer shall have delivered to the Trustee an Officers'

     and, if a supplemental indenture or supplemental Security Documents are
     required in connection with such transaction, such supplemental indenture
     and Security Documents comply with the applicable provisions of this
     Indenture, that all conditions precedent in this Indenture relating to such
     transaction have been satisfied and that supplemental indenture and
     Security Documents are enforceable;

provided, however, that clause (c)(ii) above does not apply if, in the good
faith determination of the Board of Directors, whose determination shall be
evidenced by a Board Resolution, the principal purpose of such transaction is to
change the state of incorporation of the Issuer and any such transaction shall
not have as one of its purposes the evasion of the foregoing limitations.

5.2  SUCCESSOR CORPORATION SUBSTITUTED.

     Upon any consolidation, combination or merger or any transfer of all or
substantially all of the assets of the Issuer or any Subsidiary Guarantor in
accordance with Section 5.1 in which the Issuer or such Subsidiary Guarantor, as
applicable, is not the continuing corporation, the successor Person formed by
such consolidation or into which the Issuer or such Subsidiary Guarantor is
merged or to which such conveyance, lease or transfer is made shall succeed to,
and be substituted for, and may exercise every right and power of, the Issuer or
such Subsidiary Guarantor under this Indenture and the Securities or any Note
Guarantee, as applicable, with the same effect as if such Surviving Entity had
been named as such.

6.2  ACCELERATION.

     If an Event of Default (other than an Event of Default specified in clause
(7) or (8) of Section 6.1 that occurs with respect to the Issuer) shall occur
and be continuing under this Indenture, the Trustee or the Holders of at least
25% in aggregate principal amount of the Securities then outstanding, by written
notice to the Issuer (and to the Trustee if such notice is given by the
Holders), may, and the Trustee at the request of such Holders shall, declare the
principal of, premium, if any, and accrued interest on the Securities to be
immediately due and payable. Upon a declaration of acceleration, such principal
of, premium, if any, and accrued interest shall be immediately due and payable.

     In the event of a declaration of acceleration because an Event of Default
set forth in clause (5) of Section 6.1 has occurred and is continuing, such
declaration of acceleration shall be automatically rescinded and annulled if the
event of default triggering such Event of Default pursuant to clause (5) of
Section 6.1 shall be remedied or cured by the Issuer, the relevant Subsidiary
Guarantor or the relevant Restricted Subsidiary or waived by the holders of the
relevant Indebtedness within 60 days after the declaration of acceleration with
respect thereto. If an Event of Default specified in clause (7) or (8) of
Section 6.1 shall occur with respect to the Issuer, any Subsidiary Guarantor or
any group of Subsidiaries that taken together would constitute a Significant
Subsidiary, the principal of, premium, if any, and accrued interest on the
Securities then outstanding shall automatically become and be immediately due
and payable without any declaration or other act on the part of the Trustee or
any Holder. In addition to acceleration of maturity of the Securities, if an
Event of Default occurs and is continuing, the holders of a majority of the
aggregate outstanding principal amount of the Securities and the Parity Lien
Indebtedness voting as a single class shall have the right to direct the Joint
Collateral Agent to exercise remedies with respect to the Collateral.

6.3  OTHER REMEDIES.

     If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy by proceeding at law or in equity to collect the payment of
principal of, premium, if any, and interest on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default. No remedy is exclusive of any
other remedy. All available remedies are cumulative to the extent permitted by
law.

6.4  WAIVER OF PAST DEFAULTS; RESCISSION OF ACCELERATION.

     Subject to Sections 2.9, 6.2, 6.7 and 9.2, the Holders of at least a
majority in principal amount of the outstanding Securities by written notice to
the Issuer and to the Trustee, may waive all past defaults and rescind and annul
a declaration of acceleration and its consequences if (x) all existing Events of
Default, other than the nonpayment of the principal of, premium, if any,


                                       68

<PAGE>

and accrued interest on the Securities that have become due solely by such
declaration of acceleration, have been cured or waived and (y) the rescission
would not conflict with any judgment or decree of a court of competent
jurisdiction.

6.5  CONTROL BY MAJORITY.

     The Holders of at least a majority in aggregate principal amount of the
outstanding Securities may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture, that may involve the
Trustee in personal liability, or that the Trustee determines in good faith may
be unduly prejudicial to the rights of Holders not joining in the giving of such
direction and may take any other action it deems proper that is not inconsistent
with any such direction received from Holders.

6.6  LIMITATION ON SUITS.

     A Holder may not pursue any remedy with respect to this Indenture or the
Securities unless:

     (1) the Holder gives the Trustee written notice of a continuing Event of
Default;

     (2) the Holder or Holders of at least 25% in aggregate principal amount of
outstanding Securities make a written request to the Trustee to pursue the
remedy;

     (3) such Holder or Holders offer the Trustee indemnity satisfactory to the
Trustee against any costs, liability or expense;

     (4) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer of indemnity; and

     (5) during such 60-day period, the Holders of at least a majority in
aggregate principal amount of the outstanding Securities do not give the Trustee
a direction that is inconsistent with the request.

     A Holder may not use this Indenture to prejudice the rights of another
Holder or to obtain a preference or priority over such other Holder.

6.7  RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

     Notwithstanding any other provision of this Indenture, the right of any
Holder to receive payment of the principal of or premium, if any, or interest on
a Security or to bring suit for the enforcement of any such payment, on or after
the due date expressed in the Securities, shall not be impaired or affected
without the consent of the Holder.

6.8  COLLECTION SUIT BY TRUSTEE.

     If an Event of Default in payment of principal, premium, if any, or
interest specified in clause (1) or (2) of Section 6.1 occurs and is continuing,
the Trustee may recover judgment in its own name and as trustee of an express
trust against the Issuer or any other obligor on the Securities for the whole
amount of principal, premium, if any, and accrued interest and fees remaining
unpaid, together with interest on overdue principal and premium, if any, and, to
the extent that payment of such interest is lawful, interest on overdue
installments of interest, in each case at the rate per annum borne by the
Securities and such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due to the Trustee under Section 7.7.

6.9  TRUSTEE MAY FILE PROOFS OF CLAIM.

     The Trustee may file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
to the Trustee under Section 7.7) and the Holders allowed in any judicial
proceedings relating to the Issuer, its creditors or its property and shall be
entitled and empowered to participate as a member, voting or otherwise, of any
official committee appointed for such matter, to collect and receive any monies
or other securities or property payable or deliverable upon the conversion or
exchange of the Securities or upon any such claims and to distribute the same,
and any Custodian in any such judicial proceedings is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agent and counsel, and any other
amounts due the Trustee under Section 7.7. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

6.10 PRIORITIES.

     Subject to Section 10.3 hereof and Section 5.2 of the Security Agreement,
if the Trustee collects any money or property pursuant to this Article VI, it
shall pay out the money or property in the following order:

          First: to the Trustee for amounts due under Section 7.7;

          Second: to Holders for interest accrued on the Securities, ratably,
     without preference or priority of any kind, according to the amounts due
     and payable on the Securities for interest;

          Third: to Holders for principal amounts and premium, if any, due and
     unpaid on the Securities, ratably, without preference or priority of any
     kind, according to the amounts due and payable on the Securities for
     principal; and


                                       70

<PAGE>

          Fourth: to the Issuer or, if applicable, the Subsidiary Guarantors as
     their respective interests may appear.

     The Trustee, upon prior notice to the Issuer, may fix a record date and
payment date for any payment to Holders pursuant to this Section 6.10.

6.11 UNDERTAKING FOR COSTS.

     In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant. This Section 6.11
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section
6.7, or a suit by a Holder or Holders of more than 10% in principal amount of
the outstanding Securities.

6.12 RESTORATION OF RIGHTS AND REMEDIES.

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then, and in every such case, subject to any determination in
such proceeding, the Issuer, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Issuer, Trustee and the Holders shall continue as
though no such proceeding had been instituted.

6.13 RIGHTS AND REMEDIES CUMULATIVE.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or wrongfully taken Securities in Section 2.7, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

                                   ARTICLE VII

                                     TRUSTEE

     Trustee and conforming to the requirements of this Indenture. However, the
     Trustee shall examine the certificates and opinions to determine whether or
     not they conform to the requirements of this Indenture, but need not verify
     the contents thereof.

     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.5.

risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder or to take or omit to take any action under this
Indenture or take any action at the request or direction of Holders if it shall
have reasonable grounds for believing that repayment of such funds is not
assured to it.

     (e) Every provision of this Indenture that in any way relates to the
Trustee is subject to this Section 7.1.

     (f) The Trustee shall not be liable for interest on any money received by

sole discretion may determine what action, if any, shall be taken,
notwithstanding any other provision of this Indenture.

          (k) Delivery of reports, information and documents to the Trustee
     under Section 4.10 is for informational purposes only and the Trustee's

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities and may otherwise deal with the Issuer, its Subsidiaries
(including any Subsidiary Guarantors) or their respective Affiliates with the

like rights. However, the Trustee shall comply with Sections 7.10 and 7.11.

     The Trustee shall not be responsible for and makes no representation as to
the validity or adequacy of this Indenture, any Note Guarantee, the Security
Documents, the Collateral, or the Securities, it shall not be accountable for

makes no representations with respect to the effectiveness or adequacy of this
Indenture.

7.5  NOTICE OF DEFAULT.

     If a Default or an Event of Default occurs and is continuing and the

Default or Event of Default, the Trustee shall mail to each Holder notice of the
uncured Default or Event of Default within 90


                                       74

<PAGE>

days after such Default or Event of Default occurs. Except in the case of a
Default or an Event of Default in payment of principal of, premium, if any, or
interest on, any Security including an accelerated payment and the failure to
make payment on the relevant Payment Date pursuant to an Offer to Purchase
resulting from a Change of Control, a Special Offer to Purchase or an Event of
Loss Offer to Purchase, the Trustee may withhold the notice if and so long as
the Board of Directors, the executive committee, or a trust committee of
directors and/or Responsible Officers, of the Trustee in good faith determines
that withholding the notice is in the interest of the Holders.

7.6  REPORTS BY TRUSTEE TO HOLDERS.

     Within 60 days after each January 1, beginning with January 1, 2006, the
Trustee shall, to the extent that any of the events described in TIA Section
313(a) occurred within the previous twelve months, but not otherwise, mail to
each Holder a brief report dated as of such date that complies with TIA Section
313(a). The Trustee also shall comply with TIA Sections 313(b), 313(c) and
313(d).

     A copy of each report at the time of its mailing to Holders shall be mailed
to the Issuer and filed with the Commission and each securities exchange, if
any, on which the Securities are listed.

     The Issuer shall notify the Trustee if the Securities become listed on any
securities exchange or of any delisting thereof and the Trustee shall comply
with TIA Section 313(d).

7.7  COMPENSATION AND INDEMNITY.

     The Issuer shall pay to the Trustee, from time to time, reasonable
compensation for its services hereunder. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Issuer
shall reimburse the Trustee upon request for all reasonable disbursements,
expenses and advances (including reasonable fees and expenses of counsel)
incurred or made by it in addition to the compensation for its services, except
any such disbursements, expenses and advances as may be attributable to the
Trustee's negligence, bad faith or willful misconduct. Such expenses shall
include the reasonable fees and expenses of the Trustee's agents and counsel.

     The Issuer and each of the Subsidiary Guarantors, jointly and severally,
shall indemnify the Trustee and its agents, employees, officers, stockholders
and directors for, and hold them harmless against, any loss, liability or
expense (including reasonable attorneys' fees and expenses) incurred by them
except for such losses, liabilities and expenses to the extent caused by any
negligence, bad faith or willful misconduct on their part, arising out of or in
connection with the acceptance or administration of this trust including the
cost and expense of enforcing this Indenture and the Securities against the
Issuer or the Holders (including this Section 7.7) including the reasonable
costs and expenses of defending themselves against or investigating any claim or
liability in connection with the exercise or performance of any of the Trustee's
rights, powers or duties hereunder. The Trustee shall notify the Issuer and the
Subsidiary Guarantors promptly of any claim asserted against the Trustee or any
of its agents, employees, officers, stockholders and directors for which it may
seek indemnity, provided that any failure to so notify the Issuer or any of the
Subsidiary Guarantors shall not relieve the Issuer of its indemnity


                                       75

<PAGE>

obligations hereunder. The Issuer and the Subsidiary Guarantors may, subject to
the approval of the Trustee, defend the claim and the Trustee shall cooperate in
the defense. The Trustee and its agents, employees, officers, stockholders and
directors subject to the claim may have separate counsel and the Issuer and the
Subsidiary Guarantors shall pay the reasonable fees and expenses of such
counsel; provided, however, that neither the Issuer nor any the Subsidiary
Guarantors shall be required to pay such fees and expenses if, subject to the
approval of the Trustee, they assume the Trustee's defense and there is no
conflict of interest between the Issuer, the Subsidiary Guarantors and the
Trustee and its agents, employees, officers, stockholders and directors subject
to the claim in connection with such defense as reasonably determined by the
Trustee. The Issuer and the Subsidiary Guarantors need not pay for any
settlement made without its written consent, which consent shall not be
unreasonably withheld, delayed or conditioned. The Issuer and the Subsidiary
Guarantors need not reimburse any expense or indemnify against any loss or
liability to the extent incurred by the Trustee through its negligence, bad
faith or willful misconduct.

     To secure the Issuer's and the Subsidiary Guarantors' payment obligations
in this Section 7.7, the Trustee shall have a senior claim and Lien prior to the
Securities and any other Obligations under the Security Documents against all
money or property held or collected by the Trustee, in its capacity as Trustee.

     When the Trustee incurs expenses or renders services after an Event of
Default specified in clause (7) or (8) of Section 6.1 occurs, such expenses and
the compensation for such services are intended to constitute expenses of
administration under any Bankruptcy Law and shall be paid to the extent allowed
under any Bankruptcy Law.

     Notwithstanding any other provision in this Indenture, the foregoing
provisions of this Section 7.7 shall survive the satisfaction and discharge of
this Indenture or the appointment of a successor Trustee.

7.8  REPLACEMENT OF TRUSTEE.

     The Trustee may resign at any time by so notifying the Issuer in writing.
The Holders of at least a majority in principal amount of the outstanding
Securities may remove the Trustee by so notifying the Issuer and the Trustee and
may appoint a successor Trustee. The Issuer may remove the Trustee if:

          (i) the Trustee fails to comply with Section 7.10;

          (ii) the Trustee is adjudged bankrupt or insolvent;

          (iii) a receiver or other public officer takes charge of the Trustee
     or its property; or

          (iv) the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Issuer shall notify each Holder of such event and
shall promptly appoint a successor Trustee. Within one year after the successor
Trustee takes office, the Holders of a majority in


                                       76

<PAGE>

principal amount of the Securities may appoint a successor Trustee to replace
the successor Trustee appointed by the Issuer.

     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Issuer. Immediately after that, the retiring
Trustee shall transfer, after payment of all sums then owing to the Trustee
pursuant to Section 7.7, all property held by it as Trustee to the successor
Trustee, subject to the Lien provided in Section 7.7, the resignation or removal
of the retiring Trustee shall become effective, and the successor Trustee shall
have all the rights, powers and duties of the Trustee under this Indenture. A
successor Trustee shall mail notice of its succession to each Holder.

     If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the
Holders of at least 10% in principal amount of the outstanding Securities may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

     If the Trustee fails to comply with Section 7.10, any Holder may petition
any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee.

     Notwithstanding replacement of the Trustee pursuant to this Section 7.8,
the Issuer's obligations under Section 7.7 shall continue for the benefit of the
retiring Trustee.

7.9  SUCCESSOR TRUSTEE BY MERGER, ETC.

     If the Trustee consolidates with, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation,
the resulting, surviving or transferee corporation without any further act
shall, if such resulting, surviving or transferee corporation is otherwise
eligible hereunder, be the successor Trustee; provided that such corporation
shall be otherwise qualified and eligible under this Article VII.

7.10 ELIGIBILITY; DISQUALIFICATION.

     This Indenture shall always have a Trustee who satisfies the requirement of
TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition. In addition, if the Trustee is a
corporation included in a bank holding company system, the Trustee,
independently of the bank holding company, shall meet the capital requirements
of TIA Section 310(a)(2). The Trustee shall comply with TIA Section 310(b);
provided, however, that there shall be excluded from the operation of TIA
Section 310(b)(1) any indenture or indentures under which other securities, or
certificates of interest or participation in other securities, of the Issuer are
outstanding, if the requirements for such exclusion set forth in TIA Section
310(b)(1) are met. The provisions of TIA Section 310 shall apply to the Issuer
and any other obligor of the Securities.

7.11 PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE ISSUER.

     The Trustee, in its capacity as Trustee hereunder, shall comply with TIA
Section 311(a), excluding any creditor relationship listed in TIA Section
311(b). A Trustee who has resigned or been removed shall be subject to TIA
Section 311(a) to the extent indicated.

     of such interest, to pay principal of, premium, if any, and interest on any
     Securities not previously delivered to the Trustee for cancellation to
     maturity or redemption; provided that the Trustee shall have been
     irrevocably instructed to apply such U.S. Legal Tender to the payment of
     said principal, premium, if any, and interest with respect to the
     Securities;

          (iii) the Issuer shall have paid all other sums payable by it

     and a certificate of the Issuer's independent accountants (who shall be a
     firm of established national reputation) stating that the amount deposited
     with the Trustee is sufficient to pay principal of, premium, if any, and

     After such delivery or irrevocable deposit, the Trustee upon request, on
demand of and at the expense of the Issuer, shall acknowledge in writing the
discharge of the Issuer's obligations under the Securities and this Indenture
except for those surviving obligations specified above.

8.2  LEGAL DEFEASANCE AND COVENANT DEFEASANCE.

          (a) The Issuer may, at its option by Board Resolutions of the Board of
     Directors of the Issuer, at any time, elect to have either clause (b) or

     conditions set forth in this Section 8.2, be deemed to have been discharged
     from their respective Note Obligations with respect to all outstanding
     Securities and the corresponding Note Guarantees on the date that is 123
     days after the date of the deposit referred to in Section 8.3(i)
     (hereinafter, "Legal Defeasance"). For this purpose, Legal Defeasance means
     that the Issuer shall be deemed to have paid and discharged the entire
     Indebtedness represented by the outstanding Securities, which shall
     thereafter be deemed to be "outstanding" only for the purposes of Section
     8.4 and the other Sections of this Indenture referred to in (i) and (ii)
     below, and to have satisfied all its other obligations under such
     Securities and this Indenture (and the Trustee, on demand of and at the
     expense of the Issuer, shall execute proper instruments acknowledging the
     same), and Holders of the Securities and any amounts deposited under
     Section 8.3 shall cease to be subject to any obligations to, or the rights
     of, any holder of Note Lien Obligations under Article X or otherwise,
     except for the following provisions, which shall survive until otherwise
     terminated or discharged hereunder: (i) the rights of Holders of
     outstanding Securities to receive solely from the trust fund described in
     Section 8.4, and as more fully set forth in such Section, payments in
     respect of the principal of, premium, if any, and interest on such
     Securities when such payments are due, (ii) the obligations with respect to
     such Securities under Article II and Section 4.2, (iii) the rights, powers,
     trusts, duties and immunities of the Trustee hereunder and the obligations
     in connection therewith and (iv) this Article VIII. Subject to compliance
     with this Article VIII, the Issuer may exercise its option under this
     clause (b) notwithstanding the prior exercise of its option under clause
     (c) below.

          (c) Upon the Issuer's exercise under clause (a) above of the option
     applicable to this clause (c), the Issuer and each Subsidiary Guarantor
     shall, subject to the satisfaction of the conditions set forth in Section
     8.3 and the conditions set forth in this Section 8.2, be released from
     their obligations, if any, under the covenants contained in Sections 4.3
     and 4.4 and Sections 4.12 through 4.21 and clause (ii) of Section 5.1(c)
     with respect to the outstanding Securities and the corresponding Note
     Guarantee on and after


                                       79

<PAGE>

     the date the conditions set forth below are satisfied (hereinafter,
     "Covenant Defeasance"), and the Securities shall thereafter be deemed not
     "outstanding" for the purposes of any direction, waiver, consent or
     declaration or act of Holders (and the consequences of any thereof) in
     connection with such covenants, but shall continue to be deemed
     "outstanding" for all other purposes hereunder (it being understood that
     such Securities shall not be deemed outstanding for accounting purposes)
     and Holders of the Securities and any amounts deposited under Section 8.3
     shall cease to be subject to any obligations to, or the rights of, any
     holder of Note Lien Obligations under Article X or otherwise. For this
     purpose, such Covenant Defeasance means that, with respect to the
     outstanding Securities, the Issuer may omit to comply with and shall have
     no liability in respect of any term, condition or limitation set forth in
     any such covenant, whether directly or indirectly, by reason of any
     reference elsewhere herein to any such covenant or by reason of any
     reference in any such covenant to any other provision herein or in any
     other document and such omission to comply shall not constitute a Default
     or an Event of Default under Section 6.1(iii) (to the extent pertaining to
     a default under or breach of the provisions of clause (ii) of Section
     5.1(c)), 6.1(4), 6.1(5) or 6.1(6), but, except as specified above, the
     remainder of this Indenture and such Securities shall be unaffected
     thereby.

8.3  CONDITIONS TO LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

     The following shall be the conditions to the application of either Section
8.2(b) or 8.2(c) to the outstanding Securities:

     In order to exercise either Legal Defeasance or Covenant Defeasance:

          (i) the Issuer shall have

                    (A) deposited with the Trustee, in trust, money and/or U.S.
               Government Obligations that through the payment of interest and
               principal (in respect of such U.S. Government Obligations) in
               accordance with their terms will provide money in an amount
               sufficient to pay the principal of, premium, if any, and accrued
               interest on the Securities on the Stated Maturity of such
               payments in accordance with the terms of this Indenture and the
               Securities; and

                    (B) delivered to the Trustee an Officers' Certificate and an
               Opinion of Counsel, each stating that all conditions precedent
               providing for or relating to the termination of the Issuer's
               obligations under the Securities and this Indenture have been
               complied with and a certificate of the Issuer's independent
               accountants (who shall be a firm of established national
               reputation) stating that the amount deposited with the Trustee is
               sufficient to pay principal of, premium, if any, and interest on
               the outstanding Securities to maturity or redemption.

          (ii) in the case of an election under Section 8.2(b), the Issuer shall
     have delivered to the Trustee:


                                       80

<PAGE>

                    (A) either (x) an Opinion of Counsel to the effect that
               Holders will not recognize income, gain or loss for federal
               income tax purposes as a result of the Issuer's exercise of its
               option under Section 8.2(b) and will be subject to federal income
               tax on the same amount and in the same manner and at the same
               times as would have been the case if such deposit, defeasance and
               discharge had not occurred, which Opinion of Counsel must be
               based upon (and accompanied by a copy of) a ruling of the
               Internal Revenue Service to the same effect unless there has been
               a change in applicable federal income tax law after the Issue
               Date such that a ruling is no longer required or (y) a ruling
               directed to the Trustee received from the Internal Revenue
               Service to the same effect as the aforementioned Opinion of
               Counsel; and

                    (B) an Opinion of Counsel to the effect that, subject to
               customary assumptions and exclusions, the creation of the
               defeasance trust does not violate the Investment Company Act of
               1940 and after the passage of 123 days following the deposit, the
               trust fund will not be subject to the effect of Section 547 of
               the Bankruptcy Law or Section 15 of the New York Debtor and
               Creditor Law;

          (iii) in the case of an election under Section 8.2(c), the Issuer
     shall have delivered to the Trustee (A) an Opinion of Counsel to the effect
     that, subject to customary assumptions and exclusions, the creation of the
     defeasance trust does not violate the Investment Company Act of 1940 and
     after the passage of 123 days following the deposit, the trust fund will
     not be subject to the effect of Section 547 of the Bankruptcy Law or
     Section 15 of the New York Debtor and Creditor Law, and (B) an Opinion of
     Counsel to the effect that, among other things, the Holders will not
     recognize income, gain or loss for federal income tax purposes as a result
     of the Issuer's exercise of its option under Section 8.2(c) and will be
     subject to federal income tax on the same amount and in the same manner and
     at the same times as would have been the case if such deposit and
     defeasance had not occurred;

          (iv) immediately after giving effect to such deposit on a pro forma
     basis, no Event of Default, or event that after the giving of notice or
     lapse of time or both would become an Event of Default, shall have occurred
     and be continuing on the date of such deposit or during the period ending
     on the 123rd day after the date of such deposit, and such deposit shall not
     result in a breach or violation of, or constitute a default under, any
     other agreement or instrument to which the Issuer or any of its
     Subsidiaries is a party or by which the Issuer or any of its Subsidiaries
     is bound;

          (v) if at such time the Securities are listed on a national securities
     exchange, the Issuer shall have delivered to the Trustee an Opinion of
     Counsel to the effect that the Securities will not be delisted as a result
     of such deposit, defeasance and discharge;

          (vi) the Issuer shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Issuer with the
     intent of preferring the


                                       81

<PAGE>

     Holders over any other creditors of the Issuer or with the intent of
     defeating, hindering, delaying or defrauding any other creditors of the
     Issuer or others; and

          (vii) the Issuer shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent hereunder provided for or relating to the Legal Defeasance or the
     Covenant Defeasance have been complied with.

     Notwithstanding the foregoing, the Opinions of Counsel required by clause
(ii) above of this Section 8.3 need not be delivered if all Securities not
theretofore delivered to the Trustee for cancellation (i) have become due and
payable, (ii) will become due and payable on the Maturity Date within one year
or (iii) are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption by the
Trustee in the name, and at the expense, of the Issuer.

8.4  APPLICATION OF TRUST MONEY.

     The Trustee or Paying Agent shall hold in trust U.S. Legal Tender or U.S.
Government Obligations deposited with it pursuant to this Article VIII, and
shall apply the deposited U.S. Legal Tender and the money from U.S. Government
Obligations in accordance with this Indenture to the payment of principal of,
premium, if any, and interest on the Securities.

     The Issuer shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Legal Tender or U.S.
Government Obligations deposited pursuant to Section 8.3 hereof or the
principal, premium, if any, and interest received in respect thereof other than
any such tax, fee or other charge which by law is for the account of the Holders
of the outstanding Securities.

     Anything in this Article VIII to the contrary notwithstanding, the Trustee
shall deliver or pay to the Issuer from time to time upon the Issuer's request
any U.S. Legal Tender or U.S. Government Obligations held by it as provided in
Section 8.3 which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof that would then be required to be
deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

8.5  REPAYMENT TO THE ISSUER.

     The Trustee and the Paying Agent shall pay to the Issuer upon request any
money held by them for the payment of principal, premium, if any, or interest
that remains unclaimed for two years; provided that the Trustee or such Paying
Agent, before being required to make any payment, may at the expense of the
Issuer mail to each Holder entitled to such money notice that such money remains
unclaimed and that after a date specified therein which shall be at least 30
days from the date of such publication or mailing any unclaimed balance of such
money then remaining shall be repaid to the Issuer. After payment to the Issuer,
Holders entitled to such money must look to the Issuer for payment as general
creditors unless an applicable law designates another Person.


                                       82

8.6  REINSTATEMENT.

     If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or
U.S. Government Obligations in accordance with this Article VIII by reason of
any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Issuer's obligations under this Indenture and the Securities
shall be revived and reinstated as though no deposit had occurred pursuant to
this Article VIII until such time as the Trustee or Paying Agent is permitted to
apply all such U.S. Legal Tender or U.S. Government Obligations in accordance
with this Article VIII; provided that if the Issuer has made any payment of
interest on, premium, if any, or principal of any Securities because of the
reinstatement of its obligations, the Issuer shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the U.S. Legal
Tender or U.S. Government Obligations held by the Trustee or Paying Agent.

                                   ARTICLE IX

9.1  WITHOUT CONSENT OF HOLDERS.

<PAGE>

     (10) conform this Indenture or the Security Documents to the "Description
of Notes" contained in the Offering Memorandum to the extent that such provision

Documents;

provided that the Issuer has delivered to the Trustee an Opinion of Counsel and
an Officers' Certificate, each stating that such amendment or supplement
complies with the provisions of this Section 9.1.

9.2  WITH CONSENT OF HOLDERS.

of the Security Documents otherwise than in accordance with the terms of this
Indenture or the Security Documents.

     No amendment or supplement to the provisions of this Indenture or the

9.3  [INTENTIONALLY OMITTED].

9.4  COMPLIANCE WITH TIA.

     From the date on which this Indenture is qualified under the TIA, every
amendment, waiver or supplement of this Indenture or the Securities or any Note
Guarantee shall comply with the TIA as then in effect.

9.5  REVOCATION AND EFFECT OF CONSENTS.

     Until an amendment, waiver or supplement becomes effective, a consent to it
by a Holder is a continuing consent by the Holder and every subsequent Holder of
a Security or portion of a Security that evidences the same debt as the
consenting Holder's Security, even if notation of the consent is not made on any
Security. However, any such Holder or subsequent Holder may revoke the consent
as to his Security or portion of his Security by notice to the Trustee or the
Issuer received before the date on which the Trustee receives an Officers'
Certificate certifying that the Holders of the requisite principal amount of
Securities have consented (and not theretofore revoked such consent) to the
amendment, supplement or waiver.

     The Issuer may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver. If a record date is fixed, then notwithstanding the last
sentence of the immediately preceding paragraph, those Persons who were Holders
at such record date (or their duly designated proxies), and only those Persons,
shall be entitled to revoke any consent previously given, whether or not such
Persons continue to be Holders after such record date. No such consent shall be
valid or effective for more than 90 days after such record date.

     After an amendment, supplement or waiver becomes effective, it shall bind
every Holder; provided that any such waiver shall not impair or affect the right
of any Holder to receive payment of principal of, premium, if any, and interest
on a Security, on or after the respective


                                       85

<PAGE>

due dates expressed in such Security, or to bring suit for the enforcement of
any such payment on or after such respective dates without the consent of such
Holder.

9.6  NOTATION ON OR EXCHANGE OF SECURITIES.

     If an amendment, supplement or waiver changes the terms of a Security, the
Issuer may require the Holder of the Security to deliver it to the Trustee. The
Issuer may provide the Trustee with an appropriate notation on the Security
about the changed terms and cause the Trustee to return it to the Holder at the
Issuer's expense. Alternatively, if the Issuer or the Trustee so determines, the
Issuer in exchange for the Security may issue and the Trustee shall authenticate
a new Security that reflects the changed terms. Failure to make the appropriate
notation or issue a new Security shall not affect the validity and effect of
such amendment, supplement or waiver.

9.7  TRUSTEE TO SIGN AMENDMENTS, ETC.

     The Trustee shall execute any amendment, supplement or waiver authorized
pursuant to this Article IX; provided that the Trustee may, but shall not be
obligated to, execute any such amendment, supplement or waiver which affects the
Trustee's own rights, duties or immunities under this Indenture. The Trustee
shall be entitled to receive, and shall be fully protected in relying upon, an
Opinion of Counsel and an Officers' Certificate each complying with Sections
14.4 and 14.5 and stating that the execution of any amendment, supplement or
waiver authorized pursuant to this Article IX is authorized or permitted by this
Indenture and constitutes the legal, valid and binding obligations of the Issuer
and the Subsidiary Guarantors, if applicable, enforceable in accordance with its
terms. Such Opinion of Counsel shall be at the expense of the Issuer.

                                    ARTICLE X

                                   COLLATERAL

indemnities afforded the Trustee.

     (b) Neither the Trustee nor the Joint Collateral Agent nor any of their
respective officers, directors, employees, attorneys or agents shall be
responsible for the existence, genuineness, value or protection of any
Collateral, for the legality, enforceability, effectiveness or sufficiency of
the Security Documents, for the creation, perfection, priority, sufficiency or
protection of any Note Lien, or for any failure to demand, collect, foreclose or
realize upon or otherwise enforce any of the Note Liens or the Security
Documents or for any delay in doing so.

Agent as and when the successor Trustee becomes the Trustee.

10.2 COLLATERAL AND SECURITY DOCUMENTS.

     (a) In order to secure the due and punctual payment of the Securities, the
Issuer has entered into the Security Documents to create the Note Liens and, to
the extent applicable, the Parity Liens on the Collateral (other than the Escrow
Account and the escrowed funds held therein) in accordance with the terms
thereof. In the event of a conflict between the terms of this Indenture and the
Security Documents, the Security Documents shall control.

     (b) Each Holder of a Security, by accepting such Security, (i) agrees to
all of the terms and provisions of the Security Documents, (ii) acknowledges
that all Note Lien Obligations including, without limitation, any interest that
accrues after the commencement of any case, proceeding or other action relating
to the bankruptcy, insolvency, reorganization or similar proceeding of the
Issuer or any of its Subsidiaries at the contractual rate of interest provided
for in the respective documentation for such Note Lien Obligations, whether or
not a claim for such post-petition interest is allowed in any such proceeding or
under applicable law, and (iii) directs the Trustee and the Joint Collateral
Agent to enter into the Security Documents and, unless violative of the
provisions hereof and thereof, to execute any and all documents, amendments,
waivers, consents, releases or other instruments required (or authorized) to be
executed by it pursuant to the terms thereof.

     (c) In the event that the Issuer shall issue Additional Notes pursuant to
Section 2.2, the net proceeds from any such issuance shall be immediately
deposited into an escrow account (other than the Escrow Account) pending their
investment in property or assets of a nature or type or that are used in a
Permitted Business. Such escrow account (and all cash, Treasury Securities and
other Collateral Investments therein) and such property or assets (collectively,
the "Additional Notes Collateral") shall immediately become part of the
Collateral, and the Issuer shall, or shall cause the relevant Subsidiaries to,
execute such collateral documents and other instruments and take such other
measures as shall be reasonably necessary to cause such escrow account and such
property or assets to become subject to the Note Liens securing the Note
Obligations and to perfect such Liens in respect of such escrow account and
property or assets, in each case, in the manner and to the extent required under
the Security Documents.

10.3 APPLICATION OF PROCEEDS OF COLLATERAL.

     (a) Proceeds realized by the Joint Collateral Agent from the Collateral
shall be applied:

          First, to amounts owing to the Joint Collateral Agent and the Escrow
     Agent in their respective capacities as Joint Collateral Agent and Escrow
     Agent;

          Second, to amounts owing to the Trustee in its capacity as such in
     accordance with the terms of this Indenture;

          Third, to the extent escrowed funds remain in the Escrow Account, to
     the Holders ratably in accordance with the principal of, and interest and
     premium, if any, outstanding on the Securities;


                                       87

<PAGE>

          Fourth, Equally and Ratably to the Holders and any holders of Parity
     Lien Indebtedness in accordance with the terms of this Indenture; and

          Fifth, to the Issuer and/or other Persons entitled thereto.

10.4 POSSESSION, USE AND RELEASE OF COLLATERAL.

     (a) Subject to the terms of the Security Documents, the Issuer and its
Restricted Subsidiaries shall have the right to remain in possession and retain
exclusive control of the Collateral securing the Note Obligations and the Parity
Lien Obligations (other than any cash, securities, obligations, Collateral
Investments, Temporary Cash Investments and other cash equivalents constituting
part of the Collateral and deposited with the Joint Collateral Agent, the Escrow
Agent or the Trustee in accordance with the provisions of the Security Documents
or this Indenture and other than as set forth in the Security Documents) to
freely operate the Collateral and to collect, invest and dispose of any income
therefrom.

     (b) In the event of the consummation of any sale, transfer or other
disposition of any property or assets that are subject to any Note Liens or
Parity Liens, which sale, transfer or other disposition meets the requirements
of Section 4.17, the Note Liens and Parity Liens on such property or assets (but
not the Net Cash Proceeds from such sale, transfer or other disposition) shall
be released. In addition, in the event that any real or personal property
becomes subject to a Lien created in accordance with clause (vi) of the second
paragraph of Section 4.15, and the Issuer so certifies to the Trustee and the
Joint Collateral Agent, the Note Liens and the Parity Liens on such property
shall be released.

     (c) Each Holder of a Security, by accepting such Security, acknowledges
that, notwithstanding the provisions set forth in this Section 10.4, the Issuer
and its Restricted Subsidiaries may, without any release or consent by the Joint
Collateral Agent or the Trustee, perform a number of activities in the ordinary
course in respect of the Collateral to the extent permitted pursuant to the
Security Documents and this Indenture.

10.5 OPINION OF COUNSEL.

     So long as the Security Documents have not been terminated in accordance
with the terms thereof, the Issuer shall deliver to the Trustee, so long as such
delivery is required by Section 314(b) of the TIA, promptly after the Issue Date
and thereafter, at least annually, within 30 days of January 1 of each year
(commencing with January 1, 2006), an Opinion of Counsel either stating that in
the opinion of such counsel, such action has been taken with respect to the
recording, filing, recording and refiling of this Indenture or any Security
Documents as is necessary to maintain the Note Liens, and reciting the details
of such action, or stating that in the opinion of such counsel, no such action
is necessary to maintain such Note Liens.

10.6 FURTHER ASSURANCES.

     The Issuer shall, and shall cause each of its Restricted Subsidiaries to,

Joint Collateral Agent from time to time may reasonably request, to assure and
confirm that the Joint Collateral Agent holds, for the benefit of the holders of
Note Obligations and Parity Lien Obligations, duly created, enforceable


                                       88

and perfected Liens upon the Collateral as contemplated by this Indenture and
the Security Documents, so as to render the same available for the security and
benefit of this Indenture and of Note Obligations and Parity Lien Obligations,
according to the intent and purposes herein expressed.

     Upon the request of the Joint Collateral Agent at any time and from time to
time, the Issuer shall, and shall cause each of its Restricted Subsidiaries to,
promptly execute, acknowledge and deliver such security agreements, instruments,
certificates, notices and other documents and take such other actions as the
Joint Collateral Agent may reasonably request to create, perfect, protect,
assure or enforce the Liens and benefits intended to be conferred as
contemplated by this Indenture and the Security Documents for the benefit of the
holders of Note Obligations and the holders of Parity Lien Obligations. If the
Issuer or such Restricted Subsidiary fails to do so, the Joint Collateral Agent
shall, pursuant to the terms of the Security Documents, be irrevocably
authorized and empowered, with full power of substitution, to execute,
acknowledge and deliver such security agreements, instruments, certificates,
notices and other documents and, subject to the terms of this Indenture and the
Security Documents, take such other actions in the name, place and stead of the
Issuer or such Restricted Subsidiary, but the Joint Collateral Agent shall have
no obligation to do so and no liability for any action taken or omitted by it in
good faith in connection therewith.

10.7 TRUST INDENTURE ACT REQUIREMENTS.

     The release of any Collateral from the Note Liens created by any of the
Security Documents or the release of, in whole or in part, the Note Liens
created by any of the Security Documents, shall not be deemed to impair the Note
Liens in contravention of the provisions hereof if and to the extent the
Collateral or Note Liens are released pursuant to the applicable Security
Documents and pursuant to the terms hereof. Each of the Holders acknowledge that
a release of Collateral or Note Liens strictly in accordance with the terms of
the Security Documents or the terms hereof shall not be deemed for any purpose
to be an impairment of the Security Documents or otherwise contrary to the terms
of this Indenture. The Issuer and the Restricted Subsidiaries shall comply with
TIA Section 314(d) relating to the release of property or securities from the
Note Liens but only to the extent required by the TIA.

10.8 SUITS TO PROTECT THE COLLATERAL.

     Subject to the provisions of the Security Documents, the Trustee or the
Parity Lien Representative shall have the authority to direct the Joint
Collateral Agent to institute and to maintain such suits and proceedings as the
Trustee or the Parity Lien Representative may deem expedient to prevent any
impairment of the Collateral by any acts which may be unlawful or in violation
of any of the Security Documents or this Indenture, and such suits and
proceedings as the Trustee or the Parity Lien Representative may deem expedient
to preserve or protect its interests and the interests of any holder of Note
Obligations and Parity Lien Obligations in the Collateral (including suits or
proceedings to restrain the enforcement of or compliance with any legislative or
other governmental enactment, rule or order that may be unconstitutional or
otherwise invalid if the enforcement of, or compliance with, such enactment,
rule or order would impair the Note Liens or be prejudicial to the interests of
the Holders).

10.9 PURCHASER PROTECTED.

     In no event shall any purchaser in good faith or other transferee of any
property purported to be released hereunder be bound to ascertain the authority
of the Trustee or the Parity Lien Representative to direct the Joint Collateral
Agent to execute the release or to inquire as to the satisfaction of any
conditions required by the provisions hereof for the exercise of such authority
or to see to the application of any consideration given by such purchaser or
other transferee; nor shall any purchaser or other transferee of any property or
rights permitted to be sold by this Article X, be under obligation to ascertain

applicable, to make any such sale or other transfer.

10.10 POWERS EXERCISABLE BY RECEIVER OR TRUSTEE.

     In case the Collateral shall be in the possession of a receiver or trustee,
lawfully appointed, the powers conferred in this Article X upon the Issuer or
any Restricted Subsidiary, as applicable, with respect to the release, sale or
other disposition of such property may be exercised by such receiver or trustee,
and an instrument signed by such receiver or trustee shall be deemed the
equivalent of any similar instrument of the Issuer or any Restricted Subsidiary,
as applicable, or of any Officer or Officers thereof required by the provisions
of this Article X.

     Collateral (other than the


                                       91

<PAGE>

     Escrow Account and the escrowed funds held therein) to the Joint Collateral
     Agent as security for all present and future Note Obligations and Parity
     Lien Obligations, and shall take such action to perfect such security
     interest such that after giving effect thereto the Joint Collateral Agent
     shall hold as security for all present and future Note Obligations and
     Parity Lien Obligations, a valid and perfected security interest upon all
     or substantially all of the Collateral (other than the Escrow Account and

     holders of at least 66 2/3% in principal amount of all Parity Lien

provided that the Trustee and the Joint Collateral Agent shall be permitted and

                                   ARTICLE XII

                             GUARANTEE OF SECURITIES

12.1 UNCONDITIONAL NOTE GUARANTEE.

     Subject to the provisions of this Article XII, each of the Subsidiary
Guarantors shall hereby, jointly and severally, unconditionally and irrevocably
guarantee, on an unsubordinated basis to each Holder of a Security authenticated
and delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the
Securities or the Note Obligations of the Issuer or any other Subsidiary
Guarantors to the Holders or the Trustee hereunder or thereunder, that: (a) the
principal of, premium, if any, and interest on the Securities shall be duly and
punctually paid in full when due, whether at maturity, upon redemption at the
option of Holders pursuant to the provisions of the Securities relating thereto,
by acceleration or otherwise, and interest on the overdue principal and (to the
extent permitted by law) interest, if any, on the Securities and all other Note
Obligations of the Issuer or


                                       94

<PAGE>

the Subsidiary Guarantors to the Holders or the Trustee hereunder or thereunder
(including amounts due the Trustee under Section 7.7) and all other Note
Obligations shall be promptly paid in full or performed, all in accordance with
the terms hereof and thereof; and (b) in case of any extension of time of
payment or renewal of any Securities or any of such other Note Obligations, the
same shall be promptly paid in full when due or performed in accordance with the
terms of the extension or renewal, whether at maturity, by acceleration or
otherwise. Failing payment when due of any amount so guaranteed, or failing
performance of any other Note Obligation of the Issuer to the Holders under this
Indenture or under the Securities, for whatever reason, each Subsidiary
Guarantor shall be obligated to pay, or to perform or cause the performance of,
the same immediately. An Event of Default under this Indenture or the Securities
shall constitute an event of default under the Note Guarantees, and shall
entitle the Holders, or the Trustee on behalf of the Holders, to accelerate the
Note Obligations of the Subsidiary Guarantors hereunder in the same manner and
to the same extent as the Note Obligations of the Issuer.

     Each of the Subsidiary Guarantors shall hereby agree that its Note
Obligations hereunder shall be unconditional, irrespective of the validity,
regularity or enforceability of the Securities or this Indenture, the absence of
any action to enforce the same, any waiver or consent by any Holder of the
Securities with respect to any provisions hereof or thereof, any release of any
other Subsidiary Guarantor, the recovery of any judgment against the Issuer, any
action to enforce the same, whether or not a Note Guarantee is affixed to any
particular Security, or any other circumstance which might otherwise constitute
a legal or equitable discharge or defense of a Subsidiary Guarantor. Each of the
Subsidiary Guarantors shall hereby waive the benefit of diligence, presentment,
demand of payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Issuer, any right to require a proceeding first against the
Issuer, protest, notice and all demands whatsoever and covenants that, except as
provided in this Indenture, the Securities or its Note Guarantee, its Note
Guarantee shall not be discharged except by complete performance of the
obligations contained in the Securities, this Indenture and the Note Guarantees.
Each Note Guarantee is a guarantee of payment and not of collection. If any
Holder or the Trustee is required by any court or otherwise to return to the
Issuer or to any Subsidiary Guarantor, or any custodian, trustee, liquidator or
other similar official acting in relation to the Issuer or such Subsidiary
Guarantor, any amount paid by the Issuer or such Subsidiary Guarantor to the
Trustee or such Holder, each Note Guarantee, to the extent theretofore
discharged, shall be reinstated in full force and effect. Each Subsidiary
Guarantor shall hereby further agree that, as between it, on the one hand, and
the Holders of Securities and the Trustee, on the other hand, (a) subject to
this Article XII, the maturity of the Note Obligations guaranteed hereby may be
accelerated as provided in Article VI for the purposes of the Note Guarantees,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Note Obligations guaranteed hereby, and (b) in
the event of any acceleration of such Note Obligations as provided in Article
VI, such Note Obligations (whether or not due and payable) shall forthwith
become due and payable by the Subsidiary Guarantors for the purpose of the Note
Guarantees.

     No Affiliate, stockholder, officer, director, limited liability company
member or employee, past, present or future, of any Subsidiary Guarantor, as
such, shall have any personal liability under such Subsidiary Guarantor's Note
Guarantee by reason of his, her or its status as such Affiliate, stockholder,
officer, director, limited liability company member or employee.


                                       95

<PAGE>

12.2 LIMITATIONS ON NOTE GUARANTEES.

     The Note Obligations of any Subsidiary Guarantor under its Note Guarantee
shall be limited to the maximum amount which, after giving effect to all other
contingent and fixed liabilities of such Subsidiary Guarantor (including all
Note Lien Obligations of such Subsidiary Guarantor) and after giving effect to
any collections from or payments made by or on behalf of any other Subsidiary
Guarantor in respect of the Note Obligations of such other Subsidiary Guarantor
under its Note Guarantee or pursuant to its contribution obligations under this
Indenture, shall result in the obligations of such Subsidiary Guarantor under
the Note Guarantee not constituting a fraudulent conveyance or fraudulent
transfer under federal or state law. Each Subsidiary Guarantor that makes a
payment or distribution under a Note Guarantee shall be entitled to a
contribution from each other Subsidiary Guarantor in an amount pro rata, based
on the net assets of each Subsidiary Guarantor, determined in accordance with
GAAP.

12.3 EXECUTION AND DELIVERY OF NOTE GUARANTEE.

     To further evidence the Note Guarantees set forth in Section 12.1, each
Subsidiary Guarantor hereby agrees that a notation of its Note Guarantee,
substantially in the form of Exhibit E hereto, shall be endorsed on each
Security authenticated and delivered by the Trustee. The Note Guarantee of any
Subsidiary Guarantor shall be executed on behalf of such Subsidiary Guarantor by
either manual or facsimile signature of two Officers of such Subsidiary
Guarantor, each of whom, in each case, shall have been duly authorized to so
execute by all requisite corporate action. The validity and enforceability of
any Note Guarantee shall not be affected by the fact that it is not affixed to
any particular Security.

     Each of the Subsidiary Guarantors hereby agrees that its Note Guarantee set
forth in Section 12.1 shall remain in full force and effect notwithstanding any
failure to endorse on each Security a notation of such Note Guarantee.

     If an Officer of a Subsidiary Guarantor whose signature is on this
Indenture or a Note Guarantee no longer holds that office at the time the
Trustee authenticates the Security on which such Note Guarantee is endorsed or
at any time thereafter, such Subsidiary Guarantor's Note Guarantee of such
Security shall nevertheless be valid.

     The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Note Guarantee set forth
in this Indenture on behalf of each Subsidiary Guarantor.

12.4 RELEASE OF A SUBSIDIARY GUARANTOR.

     (a) Upon (i) the sale, exchange or transfer to any Person (other than an
Affiliate of the Issuer) of all of the Capital Stock of a Subsidiary Guarantor
owned directly or indirectly by the Issuer or any Restricted Subsidiary of the
Issuer, (ii) the designation of a Subsidiary Guarantor as an Unrestricted
Subsidiary in accordance with the terms of this Indenture or (iii) the
defeasance or discharge of the Securities in accordance with the terms of this
Indenture, such Subsidiary Guarantor's (or, in the case of clause (iii), each
Subsidiary Guarantor's) Note Guarantee shall be automatically and
unconditionally discharged and such Subsidiary Guarantor shall be released from
all obligations under this Article XII without any further action required on
the part of the


                                       96

<PAGE>

Subsidiary Guarantor, the Issuer, the Trustee or any Holder. Any Subsidiary
Guarantor not so released or the entity surviving such Subsidiary Guarantor, as
applicable, shall remain or be liable under its Note Guarantee as provided in
this Article XII.

     (b) The Trustee shall deliver an appropriate instrument evidencing the
release of a Subsidiary Guarantor upon receipt of a request by the Issuer or
such Subsidiary Guarantor accompanied by an Officers' Certificate and an Opinion
of Counsel certifying as to the compliance with this Section 12.4; provided,
however, that the legal counsel delivering such Opinion of Counsel may rely as
to matters of fact on one or more Officers' Certificates of the Issuer.

     The Trustee shall execute any documents reasonably requested by the Issuer
or a Subsidiary Guarantor in order to evidence the release of such Subsidiary
Guarantor from its obligations under its Note Guarantee endorsed on the
Securities and under this Article XII.

12.5 WAIVER OF SUBROGATION.

     Until this Indenture is discharged and all of the Securities are discharged
and paid in full, each Subsidiary Guarantor shall hereby irrevocably waive and
agree not to exercise any claim or other rights which it may now or hereafter
acquire against the Issuer that arise from the existence, payment, performance
or enforcement of the Note Obligations under the Securities or this Indenture
and under its Note Guarantee, in any such instance, including, without
limitation, any right of subrogation, reimbursement, exoneration, contribution,
indemnification, and any right to participate in any claim or remedy of the
Holders against the Issuer, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from the Issuer, directly or indirectly, in cash or
other property or by set-off or in any other manner, payment or security on
account of such claim or other rights. If any amount shall be paid to any
Subsidiary Guarantor in violation of the preceding sentence and any amounts
owing to the Trustee or the Holders of Securities under the Securities, this
Indenture, or any other document or instrument delivered under or in connection
with such agreements or instruments, shall not have been paid in full, such
amount shall have been deemed to have been paid to such Subsidiary Guarantor for
the benefit of, and held in trust for the benefit of, the Trustee or the Holders
and shall forthwith be paid to the Trustee for the benefit of itself or such
Holders to be credited and applied to the obligations in favor of the Trustee or
the Holders, as the case may be, whether matured or unmatured, in accordance
with the terms of this Indenture. Each Subsidiary Guarantor acknowledges that it
will receive direct and indirect benefits from the financing arrangements
contemplated by this Indenture and that the waiver set forth in this Section
12.5 is knowingly made in contemplation of such benefits.

12.6 IMMEDIATE PAYMENT.

     Each Subsidiary Guarantor, upon the execution and delivery of a Note
Guarantee pursuant to Section 4.14, shall hereby agree to make immediate payment

12.7 NO SET-OFF.

     Each payment to be made by a Subsidiary Guarantor hereunder in respect of
the Note Obligations shall be payable in the currency or currencies in which
such Note Obligations are denominated, and shall be made without set-off,
counterclaim, reduction or diminution of any kind or nature.

12.8 NOTE OBLIGATIONS ABSOLUTE.

     The Note Obligations of each Subsidiary Guarantor hereunder are and shall
be absolute and unconditional and any monies or amounts expressed to be owing or
payable by each Subsidiary Guarantor hereunder which may not be recoverable from
such Subsidiary Guarantor on the basis of a Note Guarantee shall be recoverable
from such Subsidiary Guarantor as a primary obligor and principal debtor in
respect thereof.

12.9 NOTE OBLIGATIONS CONTINUING.

     The Note Obligations of each Subsidiary Guarantor hereunder shall be
continuing and shall remain in full force and effect until either all the
obligations have been discharged or defeased pursuant to Article VIII or

agree with the Trustee that it shall from time to time deliver to the Trustee
suitable acknowledgments of its continued liability hereunder and under any
other instrument or instruments in such form as counsel to the Trustee may
advise and as shall prevent any action brought against it in respect of any
default hereunder being barred by any statute of limitations now or hereafter in
force and, in the event of the failure of a Subsidiary Guarantor so to do, it
hereby irrevocably appoints the Trustee the attorney and agent of such
Subsidiary Guarantor to make, execute and deliver such written acknowledgment or
acknowledgments or other instruments as may from time to time become necessary
or advisable, in the judgment of the Trustee on the advice of counsel, to fully
maintain and keep in force the liability of such Subsidiary Guarantor hereunder
and under its Note Guarantee.

12.10 NOTE OBLIGATIONS NOT DISCHARGED.

     Except as provided herein, the Note Obligations of each Subsidiary
Guarantor hereunder shall not be satisfied or discharged solely by the payment

hereof be or become owing or payable under or by virtue of or otherwise in
connection with the Securities or this Indenture.

12.11 NOTE OBLIGATIONS REINSTATED.

     The Note Obligations of each Subsidiary Guarantor hereunder shall continue
to be effective or shall be reinstated, as the case may be, if at any time any
payment which would otherwise have reduced the Note Obligations of any
Subsidiary Guarantor hereunder (whether such payment shall have been made by or
on behalf of the Issuer or by or on behalf of a Subsidiary Guarantor) is
rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy,
liquidation or reorganization of the Issuer or any Subsidiary Guarantor or
otherwise, all as though such payment had not been made. If demand for, or
acceleration of the time for,

<PAGE>

payment by the Issuer is stayed upon the insolvency, bankruptcy, liquidation or
reorganization of the Issuer, all such Indebtedness otherwise subject to demand
for payment or acceleration shall nonetheless be payable by each Subsidiary
Guarantor as provided herein.

12.12 NOTE OBLIGATIONS NOT AFFECTED.

     The Note Obligations of each Subsidiary Guarantor hereunder shall, to the
extent permitted by law, not be affected, impaired or diminished in any way by
any act, omission, matter or thing whatsoever, occurring before, upon or after
any demand for payment hereunder (and whether or not known or consented to by
any Subsidiary Guarantor or any of the Holders) which, but for this provision,
might constitute a whole or partial defense to a claim against any Subsidiary
Guarantor hereunder or might operate to release or otherwise exonerate any
Subsidiary Guarantor from any of its Note Obligations hereunder or otherwise
affect such Note Obligations, whether occasioned by default of any of the
Holders or otherwise, including, without limitation:

          (i) any limitation of status or power, disability, incapacity or other
     circumstance relating to the Issuer or any other Person, including any
     insolvency, bankruptcy, liquidation, reorganization, readjustment,
     composition, dissolution, winding-up or other proceeding involving or
     affecting the Issuer or any other Person;

          (ii) any irregularity, defect, unenforceability or invalidity in
     respect of any indebtedness or other obligation of the Issuer or any other
     Person under this Indenture, the Securities or any other document or
     instrument;

          (iii) any failure of the Issuer, whether or not without fault on its
     part, to perform or comply with any of the provisions of this Indenture or
     the Securities, or to give notice thereof to a Subsidiary Guarantor;

          (iv) the taking or enforcing or exercising or the refusal or neglect
     to take or enforce or exercise any right or remedy from or against the
     Issuer or any other Person or their respective assets or the release or
     discharge of any such right or remedy;

          (v) the granting of time, renewals, extensions, compromises,

     ordinances of any jurisdiction by any present or future action of any
     governmental authority or court amending, varying, reducing or otherwise
     affecting, or purporting to amend, vary, reduce or otherwise affect, any of
     the Note Obligations or the obligations of a Subsidiary Guarantor under its
     Note Guarantee; and

          (x) any other circumstance, including release of any other Subsidiary
     Guarantor pursuant to Section 12.4 (other than by complete, irrevocable
     payment) that might otherwise constitute a legal or equitable discharge or
     defense of the Issuer under this Indenture or the Securities or of another
     Subsidiary Guarantor in respect of its Note Guarantee hereunder;

provided that the provisions of this Section 12.12 are not intended to affect in
any way any release of a Subsidiary Guarantor in accordance with the provisions
of Section 12.4.

dishonor or non-payment of any of the Note Obligations, or other notice or
formalities to the Issuer or any Subsidiary Guarantor of any kind whatsoever.

12.14 NO OBLIGATION TO TAKE ACTION AGAINST THE ISSUER.

     Neither the Trustee nor any other Person shall have any obligation to
enforce or exhaust any rights or remedies or to take any other steps under any
security for the Note Obligations or against the Issuer or any other Person or
any property of the Issuer or any other Person before the Trustee is entitled to
demand payment and performance by any or all Subsidiary Guarantors of their
liabilities and the Note Obligations under their Note Guarantees or under this
Indenture.

12.15 DEALING WITH THE ISSUER AND OTHERS.

     The Holders, without releasing, discharging, limiting or otherwise
affecting in whole or in part the Note Obligations and liabilities of any
Subsidiary Guarantor and without the consent of or notice to any Subsidiary
Guarantor, may

          (i) grant time, renewals, extensions, compromises, concessions,
     waivers, releases, discharges and other indulgences to the Issuer or any
     other Person;

          (ii) take or abstain from taking security or collateral from the
     Issuer or from perfecting security or collateral of the Issuer;

          (iii) release, discharge, compromise, realize, enforce or otherwise
     deal with or do any act or thing in respect of (with or without
     consideration) any and all collateral, mortgages or other security given by

     contemplated by this Indenture or the Securities;

     or change any such application in whole or in part from time to time as the
     Holders may see fit; and

          (vi) otherwise deal with, or waive or modify their right to deal with,
     the Issuer and all other Persons and any security as the Holders or the
     Trustee may see fit.

12.16 DEFAULT AND ENFORCEMENT.

     If any Subsidiary Guarantor fails to pay in accordance with Section 12.6,
the Trustee may proceed in its name as trustee hereunder in the enforcement of
the Note Guarantee of any such Subsidiary Guarantor and such Subsidiary

whether by legal proceedings or otherwise, and to recover from such Subsidiary
Guarantor the Note Obligations.

Guarantee.

12.20 NO MERGER OR WAIVER; CUMULATIVE REMEDIES.

     No Note Guarantee shall operate by way of merger of any of the obligations
of a Subsidiary Guarantor under any other agreement, including, without
limitation, this Indenture. No failure to exercise and no delay in exercising,
on the part of the Trustee or the Holders, any right, remedy, power or privilege
hereunder or under this Indenture or the Securities, shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder or under this Indenture or the Securities preclude any other
or further exercise thereof or the exercise of any other right, remedy, power or
privilege. The rights, remedies, powers and privileges in the Note Guarantee and
under this Indenture, the Securities and any other document or instrument
between a Subsidiary Guarantor and/or either Issuer and the Trustee are
cumulative and not exclusive of any rights, remedies, powers and privilege
provided by law.

in such case shall be enforceable against such Subsidiary Guarantor to the same
extent as prior to any such payment and without regard to and without giving
effect to any defense, right of offset or counterclaim available to or which may
be asserted by the Issuer or any Subsidiary Guarantor.

12.22 NOTE GUARANTEE IN ADDITION TO OTHER OBLIGATIONS.

                           VERASUN ENERGY CORPORATION

                       9 7/8% Senior Secured Note due 2012

1.   Interest.

     VERASUN ENERGY CORPORATION, a South Dakota corporation (the "Issuer"),
promises to pay interest on the principal amount of this Security at a rate per
annum equal to 9 7/8%. Interest on the Securities shall be payable semi-annually
in arrears on June 15 and December 15 of each year, or if any such day is not a
Business Day, on the next succeeding Business Day (each an "Interest Payment
Date"). The Issuer shall make each interest payment to the Holders of record on
the immediately preceding June 1 and December 1. Interest on the Securities
shall accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from and including the Issue Date; provided that if
there is no existing Default in the payment of interest, and if this Security is
authenticated between a Record Date referred to on the face hereof and the next
succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided, further, that the first Interest
Payment Date shall be June 15, 2006. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

     The Issuer shall pay interest ("defaulted interest") on overdue principal
and premium, if any, and interest on overdue installments of interest, to the
extent lawful, at a rate per annum that is 2.0% in excess of the rate otherwise
payable.

2.   Method of Payment.

     The Issuer shall pay interest on the Securities (except defaulted interest)
to the Persons who are the registered Holders at the close of business on the
Record Date immediately preceding the Interest Payment Date even if the
Securities are canceled on registration of transfer or registration of exchange
(including pursuant to an Exchange Offer (as defined in the Indenture)) after
such Record Date. Holders must surrender Securities to a Paying Agent to collect
principal payments. The Issuer shall pay principal, premium, if any and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts ("U.S. Legal Tender"). However, the Issuer
may pay principal, premium, if any, and interest by wire transfer of federal
funds, or interest by check payable in such U.S. Legal Tender. The Issuer may
deliver any such interest payment to the Paying Agent or to a Holder at the
Holder's registered address.

3.   Paying Agent and Registrar.

     Initially, Wells Fargo Bank, N.A. (the "Trustee") shall act as Paying Agent
and Registrar. The Issuer may change any Paying Agent, Registrar or co-Registrar
without notice to the Holders. The Issuer or any of its Subsidiaries may,
subject to certain exceptions, act as Registrar or co-Registrar.


                                       A-4

<PAGE>

4.   Indenture.

     The Issuer issued the Securities under an Indenture, dated as of December
21, 2005 (the "Indenture"), among the Issuer, the Subsidiary Guarantors and the
Trustee. This Security is one of a duly authorized issue of Securities of the
Issuer designated as its 9 7/8% Senior Secured Notes due 2012 (the "Initial
Notes"). Capitalized terms herein are used as defined in the Indenture unless
otherwise defined herein. The terms of the Securities include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the "TIA"), as in
effect on the date of the Indenture until such time as the Indenture is
qualified under the TIA, and thereafter the TIA as then in effect as amended
from time to time. Notwithstanding anything to the contrary herein, the
Securities are subject to all such terms, and Holders are referred to the
Indenture and the TIA for a statement of them. The Securities are general
obligations of the Issuer unlimited in amount, of which an aggregate principal
amount of $210,000,000 are being issued on the Issue Date. Additional Notes may
be issued pursuant to the Indenture and will be part of the same series as the
Securities; provided that any such Additional Notes, together with the Initial
Notes and the Parity Lien Indebtedness, collectively, will not exceed
$500,000,000 at any one time outstanding.

5.   Optional Redemption.

     Except as set forth in the next succeeding paragraph and Section 6 below,
the Securities shall not be redeemable at the Issuer's option prior to December
15, 2009. At any time on or after December 15, 2009, the Securities shall be
subject to redemption at the option of the Issuer, in whole or in part, upon not
less than 30 nor more than 60 days' notice, at the redemption prices (expressed
as a percentage of principal amount) set forth below, plus accrued and unpaid
interest to, but not including, the Redemption Date, if redeemed during the
12-month period commencing on December 15 of any year set forth below, subject
to the rights of Holders on the relevant Record Date to receive interest on the
relevant interest payment date:

<TABLE>
<CAPTION>
Year                  Percentage
----                  ----------
<S>                   <C>
2009                   104.938%
2010                   102.469%
2011 and thereafter    100.000%
</TABLE>

     In addition, at any time prior to December 15, 2009, the Issuer may also
redeem, in whole or in part, the Securities, upon not less than 30 nor more than
60 days prior notice, at a redemption price equal to 100% of the principal
amount of Securities to be redeemed, plus the Applicable Premium (as defined
below) as of, and accrued and unpaid interest to, but not including, the
Redemption Date, subject to the rights of the Holders on the relevant Record
Date to receive interest due on the relevant interest payment date.

     "Applicable Premium" means, with respect to any Security on any Redemption
Date, the excess of:

     (1) the present value at such Redemption Date of (i) the redemption price
of the Security on December 15, 2009 (such redemption price being set forth in
the table above), plus


                                       A-5

<PAGE>

(ii) all required interest payments due on the Security through December 15,
2009 (excluding accrued but unpaid interest to, but not including, the
Redemption Date), computed using a discount rate equal to the Treasury Rate as
of such Redemption Date plus 50 basis points; over

     (2) the principal amount of the Security.

     "Treasury Rate" means, as of any Redemption Date, the yield to maturity
(calculated on a semi-annual bond equivalent basis) as of such Redemption Date
of United States Treasury securities with a constant maturity (as compiled and
published in the most recent Federal Reserve Statistical Release H.I5 (519) (the
"Statistical Release") that has become publicly available at least two business
days prior to the Redemption Date (or, if such Statistical Release is no longer
published, any publicly available source of similar market data)) most nearly
equal to the period from the Redemption Date to December 15, 2009; provided,
however, that if the period from the Redemption Date to December 15, 2009, is
less than one year, the weekly average yield on actually traded United States
Treasury securities adjusted to a constant maturity of one year shall be used.

6    Optional Redemption with the Proceeds of Certain Equity Issuances.

     At any time prior to December 15, 2008, the Issuer may on one or more
occasions redeem up to 35% of the principal amount of the Securities then
outstanding with the Net Cash Proceeds of one or more sales of Capital Stock
(other than Disqualified Stock) of the Issuer at a redemption price of 109.875%
of the principal amount of such Securities, together with accrued and unpaid
interest to, but not including, the Redemption Date; provided that at least 65%
of the aggregate principal amount of the Securities outstanding immediately
prior to each such redemption remains outstanding immediately after each such
redemption and provided, further, that such redemption shall occur within 120
days of the date of the closing of the related sale of Capital Stock.

7.   Notice of Redemption.

     Notice of redemption shall be mailed by first-class mail at least 30 days
but not more than 60 days before the Redemption Date to each Holder to be
redeemed at such Holder's registered address. Securities in denominations of
$2,000 may be redeemed only in whole. The Trustee may select for redemption
portions (equal to $2,000 and any integral multiples of $1,000) of the principal
of Securities that have denominations larger than $1,000.

     If any Security is to be redeemed in part only, the notice of redemption
that relates to such Security shall state the portion of the principal amount
thereof to be redeemed. A new Security in a principal amount equal to the
unredeemed portion thereof shall be issued in the name of the Holder thereof
upon cancellation of the original Security. Unless the Issuer defaults in the
payment of the redemption price, on and after the Redemption Date, interest
shall cease to accrue on Securities or portions thereof called for redemption,
subject to the provisions of the Indenture.

     Any redemption and notice thereof may at the Issuer's discretion be subject
to one or more conditions precedent.

8.   Security and Lien Sharing.

     The Issuer's obligations under the Securities are secured by Note Liens on
the Collateral pursuant to the terms of the Security Documents, subject to Lien
sharing in favor of holders of future Parity Lien Indebtedness. If the Issuer
incurs any Parity Lien Indebtedness, the Note Liens (other than Liens on the
Escrow Account and the escrowed funds held therein) shall rank Equally and
Ratably with certain Parity Liens as set forth in Article XI of the Indenture.

9.   Change of Control Offer.

     Upon the occurrence of a Change of Control, the Issuer shall be required,
as and to the extent set forth in the Indenture, to Offer to Purchase all of the
outstanding Securities at a purchase price equal to 101% of the principal amount
thereof, plus accrued and unpaid interest, if any, thereon to the date of
repurchase (subject to the right of Holders of record on the relevant Record
Date to receive interest due on the relevant interest payment date).

10.  Limitation on Asset Sales.

     The Issuer is, subject to certain conditions, obligated to make an Offer to
Purchase Securities at 100% of their principal amount, plus accrued and unpaid
interest, if any, thereon to the date of repurchase with certain Net Cash
Proceeds of certain sales or other dispositions of assets in accordance with the
Indenture.

11.  Escrow of Proceeds; Special Offer to Purchase.

     The Issuer is required to make an Offer to Purchase, using funds in the
Escrow Account, up to $125,000,000 (or such lesser amount as is equal to the
amount then held in the Escrow Account) in aggregate principal amount of the
Securities on a pro rata basis if either (a) (1) the Issuer or one of its
Restricted Subsidiaries has not obtained all requisite consents, approvals,
licenses and permits required to construct the Charles City Facility in the
manner contemplated in the Offering Memorandum or (2) construction of the
Charles City Facility has not commenced, in each case, on or prior to 180 days
after the Issue Date; or (b) the Issuer shall have provided written notice to
the Trustee and the Escrow Agent at any time of its decision not to proceed with
or complete the construction of the Charles City Facility. The purchase price
shall be 100% of the principal amount of the Securities outstanding, plus
accrued and unpaid interest, if any, thereon to the date of repurchase.

12.  Events of Loss.

     The Issuer is, subject to certain conditions, obligated to make an Offer to
Purchase Securities at 100% of their principal amount, plus accrued and unpaid
interest, if any, thereon to the date of repurchase with certain Net Loss
Proceeds received by the Issuer in connection with an Event of Loss.

Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture. The Registrar need not register the transfer of or
exchange any Securities or portions thereof selected for redemption, except the
unredeemed portion of any security being redeemed in part.

15.  Persons Deemed Owners.

     The registered Holder of a Security shall be treated as the owner of it for
all purposes.

16.  Unclaimed Funds.

     If funds for the payment of principal, premium, if any, or interest remain
unclaimed for two years, the Trustee and the Paying Agent shall repay the funds
to the Issuer at its request. After that, all liability of the Trustee and such
Paying Agent with respect to such funds shall cease.

17.  Discharge Prior to Redemption or Maturity.

     The Issuer and the Subsidiary Guarantors may be discharged from their
obligations under the Indenture or the Securities and any Note Guarantee except
for certain provisions thereof, and may be discharged from obligations to comply
with certain covenants contained in the Indenture and the Securities and any
Note Guarantee, in each case upon satisfaction of certain conditions specified
in the Indenture.

18.  Amendment; Supplement; Waiver.

     Subject to certain exceptions, the Indenture, the Securities, any Note
Guarantee and the Security Documents may be amended or supplemented with the
written consent of the Holders of at least a majority in aggregate principal
amount of the Securities then outstanding, and any existing Default or Event of
Default or compliance with any provision may be waived with the consent of the
Holders of at least a majority in aggregate principal amount of the Securities

among other things, cure any ambiguity, defect or inconsistency, provide for
uncertificated Securities and any Note Guarantee in addition to or in place of
Physical Securities or comply with any requirements of the Commission in
connection with the qualification of the Indenture under the TIA, or make any
other change that does not materially and adversely affect the rights of any
Holder of a Security.

     In addition, the Trustee and the Joint Collateral Agent shall be permitted
and authorized, without the consent of any Holder, to enter into any amendments
to the Security Documents (other than the Escrow Agreement) or the Indenture to
permit, and take any other necessary action to permit, the creation and
perfection of Liens on the Collateral (other than the Escrow Account and the
escrowed funds held therein) for the benefit of holders of Parity Lien
Indebtedness to the extent such indebtedness and the Parity Liens securing such
indebtedness is permitted by the terms of the Indenture and the Security
Documents; provided, however that no amendment or supplement to the provisions
of the Indenture or the Security Documents governing the sharing of Collateral
with Parity Liens may be made unless such amendment or supplement is permitted
under Section 11.4 of the Indenture.

19.  Restrictive Covenants.

     The Indenture contains certain covenants that, among other things, limit
the ability of the Issuer and its Restricted Subsidiaries to make restricted
payments, to incur indebtedness, to create liens, to sell assets, to permit
restrictions on dividends and other payments by Restricted Subsidiaries of the
Issuer to the Issuer, to consolidate, merge or sell all or substantially all of
its assets or to engage in transactions with affiliates. The limitations are
subject to a number of important qualifications and exceptions. The Issuer must
annually report to the Trustee on compliance with such limitations.

20.  Defaults and Remedies.

     If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in aggregate principal amount of Securities then outstanding may
declare all the Securities to be due and payable immediately in the manner and
with the effect provided in the Indenture. Holders of Securities may not enforce
the Indenture, the Securities or any Note Guarantee except as provided in the
Indenture. The Trustee is not obligated to enforce the Indenture, the Securities
or the Note Guarantees, if any, unless it has received indemnity satisfactory to
it. The Indenture permits, subject to certain limitations therein provided,
Holders of at least a majority in aggregate principal amount of the Securities
then outstanding to direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders of Securities notice of certain continuing
Defaults or Events of Default if it determines that withholding notice is in
their interest.

21.  Trustee Dealings with Issuers.

     The Trustee under the Indenture, in its individual or any other capacity,
may become the owner or pledgee of Securities and may otherwise deal with the
Issuer, its Subsidiaries or their respective Affiliates as if it were not the
Trustee.

interest on any of the Securities or for any claim based thereon or otherwise in
respect thereof, and no recourse under or upon any obligation, covenant or
agreement of any Obligor in the Indenture, or in any of the Securities or Note
Guarantees or because of the creation of any Indebtedness represented thereby,
shall be had against any incorporator, stockholder, officer, director, employee
or controlling person of the Issuer or any Subsidiary Guarantor or of any
successor Person thereof. Each Holder, by accepting the Securities, waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Securities. Such waiver may not be
effective to waive liabilities under the federal securities laws.

                           VERASUN ENERGY CORPORATION

                  9 7/8% Senior Secured Exchange Note due 2012

1.   Interest.

     VERASUN ENERGY CORPORATION, a South Dakota corporation (the "Issuer"),
promises to pay interest on the principal amount of this Security at a rate per
annum equal to 9 7/8%. Interest on the Securities shall be payable semi-annually
in arrears on June 15 and December 15 of each year, or if any such day is not a
Business Day, on the next succeeding Business Day (each an "Interest Payment
Date"). The Issuer shall make each interest payment to the Holders of record on
the immediately preceding June 1 and December 1. Interest on the Securities
shall accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from and including the Issue Date; provided that if
there is no existing Default in the payment of interest, and if this Security is
authenticated between a Record Date referred to on the face hereof and the next
succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided, further, that the first Interest
Payment Date shall be June 15, 2006. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

     The Issuer shall pay interest ("defaulted interest") on overdue principal
and premium, if any, and interest on overdue installments of interest, to the
extent lawful, at a rate per annum that is 2.0% in excess of the rate otherwise
payable.

2.   Method of Payment.

     The Issuer shall pay interest on the Securities (except defaulted interest)
to the Persons who are the registered Holders at the close of business on the
Record Date immediately preceding the Interest Payment Date even if the
Securities are canceled on registration of transfer or registration of exchange
(including pursuant to an Exchange Offer (as defined in the Indenture)) after
such Record Date. Holders must surrender Securities to a Paying Agent to collect
principal payments. The Issuer shall pay principal, premium, if any and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts ("U.S. Legal Tender"). However, the Issuer
may pay principal, premium, if any, and interest by wire transfer of federal
funds, or interest by check payable in such U.S. Legal Tender. The Issuer may
deliver any such interest payment to the Paying Agent or to a Holder at the
Holder's registered address.

3.   Paying Agent and Registrar.

     Initially, Wells Fargo Bank, N.A. (the "Trustee") shall act as Paying Agent
and Registrar. The Issuer may change any Paying Agent, Registrar or co-Registrar
without notice to the Holders. The Issuer or any of its Subsidiaries may,
subject to certain exceptions, act as Registrar or co-Registrar.


                                       B-4

<PAGE>

4.   Indenture.

     The Issuer issued the Securities under an Indenture, dated as of December
21, 2005 (the "Indenture"), among the Issuer, the Subsidiary Guarantors and the
Trustee. This Security is one of a duly authorized issue of Securities of the
Issuer designated as its 9 7/8% Senior Secured Notes due 2012 (the "Initial
Notes"). Capitalized terms herein are used as defined in the Indenture unless
otherwise defined herein. The terms of the Securities include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the "TIA"), as in
effect on the date of the Indenture until such time as the Indenture is
qualified under the TIA, and thereafter the TIA as then in effect as amended
from time to time. Notwithstanding anything to the contrary herein, the
Securities are subject to all such terms, and Holders are referred to the
Indenture and the TIA for a statement of them. The Securities are general
obligations of the Issuer unlimited in amount, of which an aggregate principal
amount of $210,000,000 are being issued on the Issue Date. Additional Notes may
be issued pursuant to the Indenture and will be part of the same series as the
Initial Notes; provided that any such Additional Notes, together with the
Initial Notes and the Parity Lien Indebtedness, collectively, will not exceed
$500,000,000 at any one time outstanding.

5.   Optional Redemption.

     Except as set forth in the next succeeding paragraph and Section 6 below,
the Securities shall not be redeemable at the Issuer's option prior to December
15, 2009. At any time on or after December 15, 2009, the Securities shall be
subject to redemption at the option of the Issuer, in whole or in part, upon not
less than 30 nor more than 60 days' notice, at the redemption prices (expressed
as a percentage of principal amount) set forth below, plus accrued and unpaid
interest to, but not including, the Redemption Date, if redeemed during the
12-month period commencing on December 15 of any year set forth below, subject
to the rights of Holders on the relevant Record Date to receive interest on the
relevant interest payment date:

<TABLE>
<CAPTION>
Year                  Percentage
----                  ----------
<S>                   <C>
2009                   104.938%
2010                   102.469%
2011 and thereafter    100.000%
</TABLE>

     In addition, at any time prior to December 15, 2009, the Issuer may also
redeem, in whole or in part, the Securities, upon not less than 30 nor more than
60 days prior notice, at a redemption price equal to 100% of the principal
amount of Securities to be redeemed, plus the Applicable Premium (as defined
below) as of, and accrued and unpaid interest to, but not including, the
Redemption Date, subject to the rights of the Holders on the relevant Record
Date to receive interest due on the relevant interest payment date.

     "Applicable Premium" means, with respect to any Security on any Redemption
Date, the excess of:

     (1) the present value at such Redemption Date of (i) the redemption price
of the Security on December 15, 2009 (such redemption price being set forth in
the table above), plus


                                       B-5

<PAGE>

(ii) all required interest payments due on the Security through December 15,
2009 (excluding accrued but unpaid interest to, but not including, the
Redemption Date), computed using a discount rate equal to the Treasury Rate as
of such Redemption Date plus 50 basis points; over

     (2) the principal amount of the Security.

     "Treasury Rate" means, as of any Redemption Date, the yield to maturity
(calculated on a semi-annual bond equivalent basis) as of such Redemption Date
of United States Treasury securities with a constant maturity (as compiled and
published in the most recent Federal Reserve Statistical Release H.I5 (519) (the
"Statistical Release") that has become publicly available at least two business
days prior to the Redemption Date (or, if such Statistical Release is no longer
published, any publicly available source of similar market data)) most nearly
equal to the period from the Redemption Date to December 15, 2009; provided,
however, that if the period from the Redemption Date to December 15, 2009, is
less than one year, the weekly average yield on actually traded United States
Treasury securities adjusted to a constant maturity of one year shall be used.

6.   Optional Redemption with the Proceeds of Certain Equity Issuances.

     At any time prior to December 15, 2008, the Issuer may on one or more
occasions redeem up to 35% of the principal amount of the Securities then
outstanding with the Net Cash Proceeds of one or more sales of Capital Stock
(other than Disqualified Stock) of the Issuer at a redemption price of 109.875%
of the principal amount of such Securities, together with accrued and unpaid
interest to, but not including, the Redemption Date; provided that at least 65%
of the aggregate principal amount of the Securities outstanding immediately
prior to each such redemption remains outstanding immediately after each such
redemption and provided, further, that such redemption shall occur within 120
days of the date of the closing of the related sale of Capital Stock.

7.   Notice of Redemption.

     Notice of redemption shall be mailed by first-class mail at least 30 days
but not more than 60 days before the Redemption Date to each Holder to be
redeemed at such Holder's registered address. Securities in denominations of
$2,000 may be redeemed only in whole. The Trustee may select for redemption
portions (equal to $2,000 and any integral multiples of $1,000) of the principal
of Securities that have denominations larger than $1,000.

     If any Security is to be redeemed in part only, the notice of redemption
that relates to such Security shall state the portion of the principal amount
thereof to be redeemed. A new Security in a principal amount equal to the
unredeemed portion thereof shall be issued in the name of the Holder thereof
upon cancellation of the original Security. Unless the Issuer defaults in the
payment of the redemption price, on and after the Redemption Date, interest
shall cease to accrue on Securities or portions thereof called for redemption,
subject to the provisions of the Indenture.

     Any redemption and notice thereof may at the Issuer's discretion be subject
to one or more conditions precedent.


                                       B-6

<PAGE>

8.   Security and Lien Sharing.

     The Issuer's obligations under the Securities are secured by Note Liens on
the Collateral pursuant to the terms of the Security Documents, subject to Lien
sharing in favor of holders of future Parity Lien Indebtedness. If the Issuer
incurs any Parity Lien Indebtedness, the Note Liens (other than Liens on the
Escrow Account and any escrowed funds held therein) shall rank Equally and
Ratably with certain Parity Liens as set forth in Article XI of the Indenture.

9.   Change of Control Offer.

     Upon the occurrence of a Change of Control, the Issuer shall be required,
as and to the extent set forth in the Indenture, to Offer to Purchase all of the
outstanding Securities at a purchase price equal to 101% of the principal amount
thereof, plus accrued and unpaid interest, if any, thereon to the date of
repurchase (subject to the right of Holders of record on the relevant Record
Date to receive interest due on the relevant interest payment date).

10.  Limitation on Asset Sales.

     The Issuer is, subject to certain conditions, obligated to make an Offer to
Purchase Securities at 100% of their principal amount, plus accrued and unpaid
interest, if any, thereon to the date of repurchase with certain Net Cash
Proceeds of certain sales or other dispositions of assets in accordance with the
Indenture.

11.  Escrow of Proceeds; Special Offer to Purchase.

     The Issuer is required to make an Offer to Purchase, using funds in the
Escrow Account, up to $125,000,000 (or such lesser amount as is equal to the
amount then held in the Escrow Account) in aggregate principal amount of the
Securities on a pro rata basis if either (a) (1) the Issuer or one of its
Restricted Subsidiaries has not obtained all requisite consents, approvals,
licenses and permits required to construct the Charles City Facility in the
manner contemplated in the Offering Memorandum or (2) construction of the
Charles City Facility has not commenced, in each case, on or prior to 180 days
after the Issue Date; or (b) the Issuer shall have provided written notice to
the Trustee and the Escrow Agent at any time of its decision not to proceed with
or complete the construction of the Charles City Facility. The purchase price
shall be 100% of the principal amount of the Securities outstanding, plus
accrued and unpaid interest, if any, thereon to the date of repurchase.

12.  Events of Loss.

     The Issuer is, subject to certain conditions, obligated to make an Offer to
Purchase Securities at 100% of their principal amount, plus accrued and unpaid
interest, if any, thereon to the date of repurchase with certain Net Loss
Proceeds received by the Issuer in connection with an Event of Loss.

13.  Denominations; Transfer; Exchange.

     The Securities are in registered form, without coupons, in denominations of
$2,000 of principal amount and integral multiples of $1,000. A Holder shall
register the transfer of or


                                       B-7

<PAGE>

exchange Securities in accordance with the Indenture. The Registrar may require
a Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay certain transfer taxes or similar governmental charges
payable in connection therewith as permitted by the Indenture. The Registrar
need not register the transfer of or exchange any Securities or portions thereof
selected for redemption, except the unredeemed portion of any security being
redeemed in part.

14.  Persons Deemed Owners.

     The registered Holder of a Security shall be treated as the owner of it for
all purposes.

15.  Unclaimed Funds.

     If funds for the payment of principal, premium, if any, or interest remain
unclaimed for two years, the Trustee and the Paying Agent shall repay the funds
to the Issuer at its request. After that, all liability of the Trustee and such
Paying Agent with respect to such funds shall cease.

16.  Discharge Prior to Redemption or Maturity.

     The Issuer and the Subsidiary Guarantors may be discharged from their
obligations under the Indenture or the Securities and any Note Guarantee except
for certain provisions thereof, and may be discharged from obligations to comply
with certain covenants contained in the Indenture and the Securities and any
Note Guarantee, in each case upon satisfaction of certain conditions specified
in the Indenture.

17.  Amendment; Supplement; Waiver.

     Subject to certain exceptions, the Indenture, the Securities, any Note
Guarantee and the Security Documents may be amended or supplemented with the
written consent of the Holders of at least a majority in aggregate principal
amount of the Securities then outstanding, and any existing Default or Event of
Default or compliance with any provision may be waived with the consent of the
Holders of at least a majority in aggregate principal amount of the Securities
then outstanding. Without notice to or consent of any Holder, the parties
thereto may amend or supplement the Indenture, the Securities, the Note
Guarantees and the Security Documents to, among other things, cure any
ambiguity, defect or inconsistency, provide for uncertificated Securities and
any Note Guarantee in addition to or in place of Physical Securities or comply
with any requirements of the Commission in connection with the qualification of
the Indenture under the TIA, or make any other change that does not materially
and adversely affect the rights of any Holder of a Security.

     In addition, the Trustee and the Joint Collateral Agent shall be permitted
and authorized, without the consent of any Holder, to enter into any amendments
to the Security Documents (other than the Escrow Agreement) or the Indenture to
permit, and take any other necessary action to permit, the creation and
perfection of Liens on the Collateral (other than the Escrow Account and the
escrowed funds held therein) for the benefit of holders of Parity Lien
Indebtedness to the extent such indebtedness and the Parity Liens securing such
indebtedness is permitted by the terms of the Indenture and the Security
Documents; provided, however that no


                                       B-8

<PAGE>

amendment or supplement to the provisions of the Indenture or the Security
Documents governing the sharing of Collateral with Parity Liens may be made
unless such amendment or supplement is permitted under Section 11.4 of the
Indenture.

18.  Restrictive Covenants.

     The Indenture contains certain covenants that, among other things, limit
the ability of the Issuer and its Restricted Subsidiaries to make restricted
payments, to incur indebtedness, to create liens, to sell assets, to permit
restrictions on dividends and other payments by Restricted Subsidiaries of the
Issuer to the Issuer, to consolidate, merge or sell all or substantially all of
its assets or to engage in transactions with affiliates. The limitations are
subject to a number of important qualifications and exceptions. The Issuer must
annually report to the Trustee on compliance with such limitations.

19.  Defaults and Remedies.

     If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in aggregate principal amount of Securities then outstanding may
declare all the Securities to be due and payable immediately in the manner and

          (a) Collateral held by the Securities Intermediary for the account of
     VeraSun is, and will continue to be, credited to the Escrow Account.

          (b) The Escrow Account is a "securities account" as defined in Section
     8-501 of the UCC. The Securities Intermediary is acting as a "securities
     intermediary" as defined in Section 8-102 of the UCC with respect to the
     Escrow Account. VeraSun is the entitlement holder with respect to the
     property credited from time to time to the Escrow Account.

<PAGE>

          (c) The Securities Intermediary has credited and will continue to
     credit such assets, property and items to the Escrow Account in accordance
     with instructions given in accordance with the terms and conditions of this
     Agreement.

          (d) For the purposes of Section 8-102(a)(9)(iii) of the UCC, all
     assets, property and items from time to time carried in the Escrow Account
     shall constitute "financial assets" under Article 8 of the UCC, and the
     Securities Intermediary and VeraSun agree to treat all such assets,
     property and items as financial assets.

          (e) The Securities Intermediary's jurisdiction with respect to the
     Escrow Account for purposes of Section 8-110(e) of the UCC is, and will
     continue to be for so long as the security interest hereunder shall be in
     effect, the State of Minnesota.

          (f) The Securities Intermediary will comply with all notifications it
     receives directing it to transfer or redeem any property in the Escrow
     Account (each an "ENTITLEMENT ORDER") or other directions concerning the
     Escrow Account (including, without limitation, Entitlement Orders,
     directions to distribute to the Escrow Agent proceeds of any such transfer
     or redemption or interest or dividends on property in the Escrow Account)
     originated by the Collateral Agent without further consent by VeraSun or
     any other Person. The Collateral Agent hereby instructs the Securities
     Intermediary to follow instructions of (i) the Escrow Agent pursuant to
     Section 6, and (ii) subject to Section 5(g), VeraSun pursuant to Section 4,
     until such time as the Collateral Agent has delivered a written notice of
     exclusive control (a "NOTICE OF EXCLUSIVE CONTROL") to the Securities
     Intermediary, with a copy to the Escrow Agent, at which time the Collateral
     Agent will be deemed to have the exclusive ability to direct the
     Collateral. The Collateral Agent hereby agrees with VeraSun that it will
     not deliver a Notice of Exclusive Control unless an Event of Default (as
     defined in the Indenture) has occurred and is continuing, and shall rescind
     any such notice if any such Event of Default is cured or waived.

          (g) If the Securities Intermediary receives conflicting Entitlement
     Orders or directions from the Collateral Agent and VeraSun, it will follow
     the Entitlement Orders and directions from the Collateral Agent and not
     from VeraSun.

          (h) The Securities Intermediary has not entered into and will not
     enter into any agreement with any other Person relating to the Escrow
     Account and/or any financial assets credited thereto pursuant to which it
     has agreed to comply with Entitlement Orders of such Person. The Securities
     Intermediary has not entered into any other agreement with VeraSun or any
     other Person purporting to limit or condition the obligation of the
     Securities Intermediary to comply with Entitlement Orders originated by the
     Collateral Agent as set forth in paragraph (f) above.

          (i) The Securities Intermediary hereby waives and releases any Lien,
     right of set-off or other right it may have against the Escrow Account or
     any financial asset carried in the Escrow Account or any credit balance in
     the Escrow Account and agrees that it will not assert any such Lien or
     right against the Escrow Account or any financial asset carried in the
     Escrow Account or any credit balance in the Escrow Account.

<PAGE>

          (j) Anything herein to the contrary notwithstanding, the Securities
     Intermediary will not be required to follow any instruction that would
     violate any applicable law, decree, regulation or order of any government
     or governmental body (including any court or tribunal).

          (k) The Securities Intermediary does not know of any claim to or
     interest in the Escrow Account or any property credited to the Escrow
     Account, except for claims and interests of the parties referred to in this
     Agreement.

          (l) When the Securities Intermediary has received any written notice
     of any claim or interest in the Escrow Account or any property credited to
     the Escrow Account other than the claims and interests of the parties
     referred to in this Agreement, the Securities Intermediary will promptly
     notify the Escrow Agent, the Collateral Agent, the Trustee and VeraSun of
     such claim or interest.

          SECTION 6. Disbursements. Prior to the receipt of a Notice of
Exclusive Control, the Escrow Agent shall instruct the Securities Intermediary
to hold the assets in the Escrow Account and release the same, or a portion
thereof, as follows:

          (a) If the Escrow Agent receives, prior to 12:00 p.m., New York City
     time, on any Business Day, or if after 12:00 p.m., New York City time, the
     next preceding Business Day, a resolution from the Board of Directors of
     VeraSun set forth in an Officers' Certificate substantially in the form of
     Exhibit A (a "COMPLETION CERTIFICATE") certifying that, as of the date of
     such certificate, (i) it has received a certificate from Fagen, Inc.
     stating that the Charles City Construction has been completed, (ii) such
     construction has resulted in production capacity of at least 110.0 million
     gallons of ethanol annually, (iii) all material consents, approvals,
     licenses and permits necessary for the commercial operation of the Charles
     City Facility have been obtained from the relevant governmental authorities
     and (iv) no Default or Event of Default has occurred and is continuing,
     with a copy sent to the Trustee, the Escrow Agent shall instruct the
     Securities Intermediary to use reasonable best efforts to liquidate, on
     such date (but in any event such liquidation and distribution shall occur
     not later than the following Business Day), all funds and/or Cash
     Equivalents and/or Collateral Investments from the Escrow Account and to
     cause the disbursement of such funds and/or Collateral Investments as
     directed by VeraSun.

          (b) If at any time prior to the presentation by VeraSun of a
     Completion Certificate the Escrow Agent receives, prior to 12:00 p.m., New
     York City time, on any Business Day, or if after 12:00 p.m., New York City
     time, the next preceding Business Day, a request by VeraSun for the
     disbursement of funds from the Escrow Account set forth in an Officers'
     Certificate substantially in the form of Exhibit B (a "DISBURSEMENT REQUEST
     CERTIFICATE") (i) indicating in reasonable detail the purpose or purposes
     to which such funds will be applied and (ii) certifying that (x) the funds
     will be used in connection with the Charles City Construction in a manner
     consistent with the terms hereof and of the Indenture, (y) the use of such
     funds for such purpose or purposes will not violate the terms of the
     Indenture, and (z) such funds will be applied as set forth in clause (i)
     within no more than ten Business Days after their release from the Escrow
     Account, with a copy

<PAGE>

     sent to the Trustee, the Escrow Agent shall instruct the Securities
     Intermediary to use reasonable best efforts to liquidate, on such date (but
     in any event such liquidation and distribution shall occur not later than
     the following Business Day), the funds and/or Collateral Investments from
     the Escrow Account in an amount equal to the amount specified in the
     Disbursement Request Certificate and to cause the disbursement of such
     amount of funds and/or Collateral Investments as directed by VeraSun;
     provided, however, that in the event that the amount requested by VeraSun
     under a Disbursement Request Certificate is equal to or greater than $15
     million or such requested amount is less than $15 million but, when added
     to all other amounts released pursuant to this Section 6(b) during the
     preceding 30 days, would aggregate to $35 million or more, the Escrow Agent
     shall not honor such Disbursement Request Certificate unless such
     Certificate is accompanied by a resolution of the Board of Directors of
     VeraSun approving such disbursement request.

          (c) In the event that the Escrow Agent receives a Special Offer to
     Purchase Notice, the Escrow Agent shall instruct the Securities
     Intermediary to liquidate and release to the Paying Agent (as defined in
     the Special Offer to Purchase Notice), not later than the last Business Day
     prior to the Payment Date (as set forth in the Special Offer to Purchase
     Notice), the funds and/or Collateral Investments from the Escrow Account in
     an amount equal to the lesser of (I) the amount required to pay the
     purchase price, plus accrued and unpaid interest to the date of purchase,
     for all notes tendered pursuant to a Special Offer to Purchase Notice and
     (II) the amount of funds and/or Collateral Investments then in the Escrow
     Account. Concurrently with the release of funds to the Paying Agent, the
     Escrow Agent will release any excess of escrowed funds over the purchase
     price to VeraSun, and VeraSun will be permitted to use the excess funds for
     any purpose not otherwise prohibited by the Indenture.

          (d) Upon the release of any Collateral from the Escrow Account in
     accordance with the terms of this Agreement, the security interest
     evidenced by this Agreement in such released Collateral and all Proceeds
     arising from such Collateral will automatically terminate and be of no
     further force and effect.

          (e) The Escrow Agent shall not be required to instruct the Securities
     Intermediary to liquidate any Collateral Investment in order to make any
     payment hereunder except as required under Section 6(a), (b) or (c).

          (f) VeraSun acknowledges, confirms and agrees that the Collateral
     Agent holds the Pledged Security Entitlements to the Collateral Investments
     solely as Collateral Agent for the Trustee and the Holders of the Notes and
     not as a securities intermediary or financial intermediary.

          (g) Nothing in this Section 6 shall affect the Escrow Agent's rights,
     upon instruction from the Collateral Agent, to instruct the Securities
     Intermediary to release Collateral for application thereof to payment of
     amounts due on the Notes upon acceleration thereof.

<PAGE>

          SECTION 7. Representations and Warranties. To induce the Secured
Parties to purchase the Notes and to induce the Escrow Agent and the Securities
Intermediary to enter into this Agreement, VeraSun hereby represents and
warrants that:

          (a) The execution and delivery by VeraSun and the performance by
     VeraSun of its obligations under this Agreement will not contravene (i) any
     provision of applicable law or the certificate of incorporation or by-laws
     of VeraSun, (ii) any material agreement or other material instrument
     binding upon VeraSun or any of its subsidiaries or (iii) any judgment,
     order or decree of any governmental body, agency or court having
     jurisdiction over VeraSun or any of its subsidiaries, or result in the
     creation or imposition of any Lien on any assets of VeraSun, except for the
     security interests granted under this Agreement and except, in the case of
     the foregoing clauses (ii) and (iii), such contraventions as would not,
     singly or in the aggregate, have a Material Adverse Effect.

          (b) No consent of any other Person and no approval, authorization,
     order of, declaration or qualification with, any governmental body or
     agency or other third party is required (i) for the execution, delivery or
     performance by VeraSun of its obligations under this Agreement or (ii) for
     the pledge by VeraSun of the Collateral pursuant to this Agreement or for
     the perfection and maintenance of such pledge, except for (1) those already
     obtained which are in full force and effect, (2) any such consents,
     approvals, authorizations or orders as may be required to be obtained by
     the Collateral Agent (or the Holders) for the exercise by the Collateral
     Agent of the rights provided for in this Agreement or the remedies in
     respect of the Collateral pursuant to this Agreement and (3) as would not,
     singly or in the aggregate, have a material adverse effect on the financial
     condition or results of operations of the Company and its Subsidiaries
     taken as a whole.

          (c) VeraSun is the legal and beneficial owner of the Collateral, free
     and clear of any Lien or claims of any Person (except for the security
     interests created by this Agreement). No financing statement or instrument
     similar in effect covering all or any part of VeraSun's interest in the
     Collateral is on file in any public or recording office.

          (d) This Agreement has been duly authorized, validly executed and
     delivered by VeraSun and constitutes a valid and binding agreement of
     VeraSun, enforceable against VeraSun in accordance with its terms, except
     as the enforceability hereof may be limited by (i) applicable bankruptcy,
     insolvency or similar laws affecting creditors' rights generally, or (ii)
     general principles of equity, whether considered at law or at equity,
     including, without limitation, concepts or materiality, reasonableness,
     good faith and fair dealing.

          (e) Upon the filing of all necessary Uniform Commercial Code financing
     statements in the proper filing offices and all other actions necessary or
     desirable to perfect a security interest in the Escrow Account, the
     security interests in the Escrow Account granted to the Collateral Agent,
     for the ratable benefit of the Secured Parties, will constitute a valid and
     perfected first priority security interest in the Escrow Account, securing
     the Obligations, subject only to Permitted Liens and other Liens expressly
     permitted under the Indenture. As of the Closing Date, except for the
     filing of all

<PAGE>

     necessary Uniform Commercial Code financing statements in the proper filing
     offices and the other filings and actions contemplated hereby and by the
     Indenture, all other filings and other actions necessary or desirable to
     perfect the security interest in the Escrow Account will have been duly
     made or taken and will be in full force and effect.

          (f) There are no legal or governmental proceedings pending or, to the
     best of VeraSun's knowledge, threatened to which VeraSun or any of its
     subsidiaries is a party or to which any of the properties of VeraSun or any
     such subsidiary is subject that would materially adversely affect the power
     or ability of VeraSun to perform its obligations under this Agreement or to
     consummate the transactions contemplated hereby.

          (g) The pledge of the Collateral pursuant to this Agreement is not
     prohibited by law or governmental regulation (including, without
     limitation, Regulations T, U and X of the Board of Governors of the Federal
     Reserve System) applicable to VeraSun.

          (h) No Event of Default exists.

          (i) VeraSun's exact legal name, as defined in Section 9-503(a) of the
     UCC, is "VeraSun Energy Corporation". The chief place of business and chief
     executive office of VeraSun are located at 100 22nd Avenue, Brookings,
     South Dakota 57006, and VeraSun keeps its records concerning the Collateral
     at such location.

          (j) VeraSun is the sole account holder of the Escrow Account and
     VeraSun has not consented to, and is not otherwise aware of any Person
     (other than the Collateral Agent) having "control" (within the meaning of
     Section 9-104 of the UCC) over the Escrow Account or any money or other
     property deposited therein.

          SECTION 8. Power of Attorney; Collateral Agent May Perform. Subject to
the terms of this Agreement, VeraSun hereby appoints and constitutes the
Collateral Agent as VeraSun's attorney-in-fact (with full power of
substitution), with full authority in the place and stead of VeraSun and in the
name of VeraSun or otherwise, from time to time to take any action and to
execute any instrument that is necessary or advisable or that the Collateral
Agent may deem necessary or advisable to accomplish the purposes of this
Agreement, including, without limitation:

          (a) to ask for, demand, collect, sue for, recover, compromise, receive
     and give acquittance and receipts for moneys due and to become due under or
     in respect of any of the Collateral,

          (b) to receive, indorse and collect any drafts or other instruments,
     documents and chattel paper, in connection with clause (a) above,

          (c) to file any claims or take any action or institute any proceedings
     that are necessary or desirable or that the Collateral Agent may deem
     necessary or desirable for the collection of any of the Collateral or
     otherwise to enforce the rights of the Trustee with respect to any of the
     Collateral,

<PAGE>

          (d) to pay or discharge taxes or Liens levied or placed upon the
     Collateral, the legality or validity thereof and the amounts necessary to
     discharge the same to be determined by the Collateral Agent, and such
     payments made by the Collateral Agent to become part of the Obligations of
     VeraSun to the Trustee, due and payable immediately upon demand, and

          (e) to convey any item of Collateral to any purchaser thereof and give
     any notices or recordings of any Liens under Section 11 hereof;

provided, however, that the Collateral Agent shall have no duty or obligation to
perform any of the foregoing actions. The Collateral Agent's authority under
this Section 8 shall include, without limitation, the authority to execute or
endorse (a) any checks or instruments representing proceeds of Collateral in the
name of VeraSun, (b) any receipts for any certificate of ownership or any
document constituting Collateral or transferring title to any item of
Collateral, (c) any financing statements (to the extent permitted by applicable
law) or (d) any other documents deemed necessary or appropriate by the
Collateral Agent or otherwise to preserve, protect or perfect the security
interest in the Collateral and to file the same, prepare, file and sign
VeraSun's name on any notice of Lien, and to take any other actions arising from
or incident to the powers granted to the Collateral Agent in this Agreement.
This power of attorney, which will terminate upon the termination of this
Agreement, is coupled with an interest and is irrevocable by VeraSun.

          SECTION 9. No Assumption of Duties; Reasonable Care. The rights and
powers conferred on the Collateral Agent hereunder are solely to preserve and
protect the security interest of the Secured Parties in and to the Collateral
granted hereby and shall not be interpreted to, and shall not impose any duties
or obligations on the Collateral Agent in connection therewith other than those
expressly provided herein or imposed under applicable law. Except as provided by
applicable law or by the Indenture, the Collateral Agent shall be deemed to have
exercised reasonable care in the custody and preservation of the Collateral in
its possession if the Collateral is accorded treatment substantially equal to
that which the Collateral Agent accords similar property held by the Collateral
Agent for its own account, it being understood that the Collateral Agent in its
capacity as such shall not have any responsibility for (a) ascertaining or
taking action with respect to calls, conversions, exchanges, maturities or other
matters relative to any Collateral, whether or not the Collateral Agent has or
is deemed to have knowledge of such matters, (b) taking any necessary steps to
preserve rights against any parties with respect to any Collateral or (c)
investing or reinvesting any of the Collateral or any loss on any investment.

          SECTION 10. Indemnity; Escrow Agent's Limitation of Liability to
VeraSun. (a) VeraSun shall indemnify, reimburse, hold harmless and defend the
Escrow Agent, the Collateral Agent and the Securities Intermediary and their
affiliates and their directors, officers, agents and employees, from and against
any and all claims, actions, obligations, liabilities and expenses, including
reasonable defense costs, reasonable investigative fees and costs, and
reasonable legal fees and damages arising from the Escrow Agent's or Securities
Intermediary's or Collateral Agent's performance or lack of performance as
Escrow Agent or Securities Intermediary or Collateral Agent, respectively, under
this Agreement, except to the extent that such claim, action, obligation,
liability or expense is directly caused by the bad faith, gross negligence or
willful misconduct of such indemnified person; provided, however, that the

<PAGE>

Securities Intermediary (a) shall not be excused from, and shall not be excused
from liability for, acting or refraining from acting and (b) shall not be
indemnified or held harmless under this Section 10 for the taking or the failure
to take any action, in each case, hereunder in its capacity as Securities
Intermediary to the extent the taking or the failure to take any such action
violates the duties and obligations expressly imposed upon the Securities
Intermediary under the Federal Book-Entry Regulations or Article 8, Part 5 of
the UCC. This indemnity shall be a continuing obligation of VeraSun, its
respective successors and assigns, notwithstanding the termination of this
Agreement and the resignation or removal of the Escrow Agent or the Securities
Intermediary or the Collateral Agent.

          (b) If at any time the Escrow Agent is served with any judicial or
administrative order, judgment, decree, writ or other form of judicial or
administrative process which in any way affects Collateral (including, but not
limited to, orders of attachment or garnishment or other forms of levies or
injunctions or stays relating to the transfer of Collateral), the Escrow Agent
is authorized to comply therewith in any manner as it or its legal counsel of
its own choosing deems appropriate and if the Escrow Agent complies with any
such judicial or administrative order, judgment, decree, writ or other form of
judicial or administrative process, the Escrow Agent shall not be liable to
VeraSun even though such order, judgment, decree, writ or process may be
subsequently modified or vacated or otherwise determined to have been without
legal force or effect.

          (c) Should any controversy arise involving the parties hereto or any
of them or any other person, firm or entity with respect to this Agreement or
the Collateral, or should a substitute escrow agent fail to be designated as
provided in Section 13.14 hereof, or if Escrow Agent should be in doubt as to
what action to take, Escrow Agent shall have the right, but not the obligation,
either to (a) withhold delivery of the Collateral until the controversy is
resolved, the conflicting demands are withdrawn or its doubt is resolved or (b)
institute a petition for interpleader in any court of competent jurisdiction to
determine the rights of the parties hereto. In the event Escrow Agent is a party
to any dispute, Escrow Agent shall have the additional right to refer such
controversy to binding arbitration. Should a petition for interpleader be
instituted, or should Escrow Agent be threatened with litigation or become
involved in litigation or binding arbitration in any manner whatsoever in
connection with this Escrow Agreement or the Collateral, VeraSun agrees to
reimburse Escrow Agent for its reasonable attorneys' fees and any and all other
reasonable expenses, losses, costs and damages incurred by Escrow Agent in
connection with or resulting from such threatened or actual litigation or
arbitration prior to any disbursement hereunder.

          (d) The Escrow Agent, the Securities Intermediary and the Collateral
Agent shall not incur any liability to VeraSun for not performing any act or
fulfilling any duty, obligation or responsibility hereunder by reason of any
occurrence beyond the control of the Escrow Agent or the Collateral Agent
(including, but not limited to, any act or provision or any present or future
law or regulation or governmental authority, any act of God or war, or the
unavailability of the Federal Reserve Bank wire or telex or other wire or
communication facility).

          (e) The Escrow Agent, the Securities Intermediary and the Collateral
Agent shall not be responsible in any respect for the form, execution, validity,
value or genuineness of

<PAGE>

documents or securities deposited hereunder, or for any description therein, or
for the identity, authority or rights of persons executing or delivering or
purporting to execute or deliver any such document, security or endorsement. In
no event shall the Escrow Agent, the Securities Intermediary or the Collateral
Agent be liable for special, indirect or consequential loss or damage of any
kind whatsoever (including but not limited to lost profits), even if the Escrow
Agent, the Securities Intermediary or the Collateral Agent have been advised of
the likelihood of such loss or damage and regardless of the form of action.

          SECTION 11. Remedies upon Events of Default. If any Event of Default
shall have occurred and be continuing:

          (a) The Collateral Agent may exercise, in addition to all other rights
     given by law or by this Agreement or the Indenture, all of the rights and
     remedies with respect to the Collateral of a secured party under the UCC at
     that time and also may without notice, sell the Collateral or any part
     thereof in one or more parcels at any broker's board or at public or
     private sale, in one or more sales or lots, at any of the Collateral
     Agent's offices or elsewhere, for cash, on credit or for future delivery,
     and upon such other terms as the Collateral Agent may deem commercially
     reasonable. The Collateral Agent shall not be obligated to make any sale of
     Collateral regardless of notice of sale having been given. The Collateral
     Agent may adjourn any public or private sale from time to time by
     announcement at the time and place fixed therefor, and such sale may,
     without further notice, be made at the time and place to which it was so
     adjourned. The purchaser of any or all Collateral so sold shall thereafter
     hold the same absolutely, free from any claim, encumbrance or right of any
     kind whatsoever created by or through VeraSun. Any sale of the Collateral
     conducted in conformity with reasonable commercial practices of banks,
     insurance companies, commercial finance companies, or other financial
     institutions disposing of property similar to the Collateral shall be
     deemed to be commercially reasonable. The Trustee, the Collateral Agent or
     any Holder of Notes may, in its own name or in the name of a designee or
     nominee, buy any of the Collateral at any public sale and, if permitted by
     applicable law, at any private sale. All reasonable expenses (including
     court costs and reasonable attorneys' fees, expenses and disbursements) of,
     or incident to, the enforcement of any of the provisions hereof shall be
     recoverable from the proceeds of the sale or other disposition of the
     Collateral.

          (b) All cash proceeds received by the Collateral Agent in respect of
     any sale of, collection from, or other realization upon all or any part of
     the Collateral may, in the discretion of the Collateral Agent, be held by
     the Collateral Agent as collateral for, and/or then or at any time
     thereafter applied to, all or any part of the Obligations in such order as
     the Collateral Agent shall elect consistent with Section 6.10 of the
     Indenture and the Security Agreement. Any surplus of such cash or cash
     proceeds held by the Collateral Agent and remaining after payment in full
     of all the Obligations shall be paid over to VeraSun.

          (c) VeraSun further agrees to use its reasonable best efforts to do or
     cause to be done all such other acts as may be necessary to ensure that
     such sale or sales of all or any portion of the Collateral pursuant to this
     Section 11 are valid and binding and in compliance with any and all other
     applicable requirements of law. VeraSun further

<PAGE>

     agrees that a breach of any of the covenants contained in this Section 11
     will cause irreparable injury to the Trustee and the Holders of the Notes,
     that the Trustee and the Holders of the Notes have no adequate remedy at
     law in respect of such breach and, as a consequence, that each and every
     covenant contained in this Section 11 shall be specifically enforceable
     against VeraSun, and VeraSun hereby waives and agrees not to assert any
     defenses against an action for specific performance of such covenants
     except for a defense that no Event of Default has occurred.

          (d) The Collateral Agent may but is not obligated to exercise any and
     all rights and remedies of VeraSun in respect of the Collateral.

          (e) Subject to and in accordance with the terms of this Agreement, all
     payments received by VeraSun in respect of the Collateral shall be received
     in trust for the benefit of the Collateral Agent, shall be segregated from
     other funds of VeraSun and shall be forthwith paid over to the Collateral
     Agent in the same form as so received (with any necessary endorsement).

          SECTION 12. Expenses. VeraSun agrees to pay to the Escrow Agent the
reasonable fees as may be agreed upon from time to time in accordance with the
Escrow Agent's fee schedule attached hereto as Schedule I, as such Schedule I
may be amended from time to time in the ordinary course of the Escrow Agent's

               13.2 Severability. The provisions of this Agreement are
severable, and if any clause or provision shall be held invalid, illegal or
unenforceable in whole or in part in any jurisdiction, then such invalidity or
unenforceability shall affect in that jurisdiction only such clause or
provision, or part thereof, and shall not in any manner affect such clause or
provision in any other jurisdiction or any other clause or provision of this
Agreement in any jurisdiction.

               13.3 Headings. The headings in this Agreement have been inserted
for convenience of reference only, are not to be considered a part hereof and
shall in no way modify or restrict any of the terms or provisions hereof.

               13.4 Counterpart Originals. This Agreement may be signed in
separate counterparts, each of which shall be deemed an original, but all of
which shall together constitute one and the same agreement. All signatures of
the parties to this agreement may be transmitted by facsimile, and such
facsimile will, for all purposes, be deemed to be the original signature of such
party whose signature it reproduces, and will be binding upon such party.

               13.5 Benefits of Agreement. Nothing in this Agreement, express or
implied, shall give to any person, other than the parties hereto and their
successors hereunder, and the Holders of the Notes, any benefit or any legal or
equitable right, remedy or claim under this Agreement.

               13.6 Amendments, Waivers and Consents. None of the terms or
provisions of this Agreement may be waived, amended, supplemented or otherwise
modified except in accordance with Article 9 of the Indenture and pursuant to a
written instrument executed by all the parties hereto. None of the Trustee, the
Escrow Agent, the Securities Intermediary, the Collateral Agent or any Holder of
Notes shall be deemed, by any act, delay, indulgence, omission or otherwise, to
have waived any right or remedy hereunder or to have acquiesced in any default
or Event of Default or in any breach of any of the terms and conditions hereof.
Failure of the Trustee, the Escrow Agent, the Securities Intermediary, the
Collateral Agent or any Holder of Notes to exercise, or delay in exercising, any
right, power or privilege hereunder shall not preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. A
waiver by the Trustee, the Escrow Agent, the Collateral Agent, the Securities
Intermediary or any Holder of Notes of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy that the
Trustee, the Escrow Agent, the Securities Intermediary, the Collateral Agent or
such Holder of Notes would otherwise have on any future occasion. The rights and
remedies herein provided are cumulative, may be exercised singly or concurrently
and are not exclusive of any rights or remedies provided by law.

               13.7 Continuing Security Interest; Termination. (a) This
Agreement shall create a continuing security interest in and to the Collateral
and shall, unless otherwise provided in this Agreement, remain in full force and
effect until the earlier of (i) the discharge or defeasance of all obligations
of VeraSun under the Indenture pursuant to Article 8 of the Indenture or (ii)
disbursement of all of the Collateral pursuant to Section 6. This Agreement
shall be binding upon VeraSun and its transferees, successors and assigns, and
shall inure, together with the rights and remedies of the Trustee and the
Collateral Agent hereunder, to the

<PAGE>

benefit of the Trustee, the Collateral Agent, the Holders of the Notes and their
respective successors, transferees and assigns.

               (b) This Agreement (other than VeraSun's obligations under
Sections 10 and 12) shall terminate upon the earlier of (i) the discharge or
defeasance of all obligations of VeraSun under the Indenture pursuant to Article
8 of the Indenture or (ii) disbursement of all of the Collateral pursuant to
Section 6.

               (c) At such time as set forth in (a) or (b) above, the Collateral
Agent shall, pursuant to a written order of VeraSun, reassign and redeliver to
VeraSun all of the Collateral hereunder that has not been sold, disposed of,
retained or applied by the Collateral Agent in accordance with the terms of this
Agreement and the Indenture and take all actions requested by VeraSun that are
necessary to release the security interest created by this Agreement in and to
the Collateral, including the filing of all termination statements provided to
it necessary to terminate any financing or continuation statements filed with
respect to the Collateral. Such reassignment and redelivery shall be without
warranty by or recourse to the Collateral Agent or the Trustee in its capacity
as such and shall be at the reasonable expense of VeraSun.

               13.8 Survival of Representations and Covenants. All
representations, warranties and covenants of VeraSun contained herein shall
survive the execution and delivery of this Agreement, and shall terminate only
upon the termination of this Agreement. The obligations of VeraSun under
Sections 10 and 12 hereof shall survive the termination of this Agreement.

               13.9 Waivers. VeraSun waives presentment and demand for payment
of any of the Obligations, protest and notice of dishonor or default with
respect to any of the Obligations, and all other notices to which VeraSun might
otherwise be entitled, except as otherwise expressly provided herein or in the
Indenture.

               13.10 Authority of the Collateral Agent and the Escrow Agent. The
Collateral Agent shall have and be entitled to exercise all powers hereunder
that are specifically granted to the Collateral Agent by the terms hereof,
together with such powers as are reasonably incident thereto but no duties,
obligations or powers shall be inferred or implied. The Collateral Agent may
perform any of its duties hereunder or in connection with the Collateral by or
through agents, attorneys, experts, accountants, advisors or employees and the
exculpatory provisions provided herein shall be equally applicable to such
Persons. The Collateral Agent shall be entitled to retain counsel and to act in
reliance upon the advice of counsel concerning any matters arising hereunder.
Except as otherwise expressly provided in this Agreement or the Indenture,
neither the Collateral Agent nor any director, officer, employee, attorney or
agent of the Collateral Agent shall be liable to VeraSun for any action taken or
omitted to be taken by the Collateral Agent, in its capacity as Collateral
Agent, hereunder, except for its own bad faith, gross negligence or willful
misconduct. The Collateral Agent and its directors, officers, employees,
attorneys and agents shall be entitled to conclusively rely on any
communication, instrument or document (whether in its original or facsimile
form)

<PAGE>

believed by it or them to be genuine and correct and to have been signed or sent
by the proper person or persons.

               (b) VeraSun acknowledges that the rights and responsibilities of
     the Collateral Agent under this Agreement with respect to any action taken
     by the Collateral Agent or the exercise or non-exercise by the Collateral
     Agent of any option, right, request, judgment or other right or remedy
     provided for herein or resulting or arising out of this Agreement shall, as
     between the Collateral Agent and the Holders of the Notes, be governed by
     the Indenture and by such other agreements with respect thereto as may
     exist from time to time among them, but, as between the Collateral Agent
     and VeraSun, the Collateral Agent shall be conclusively presumed to be
     acting as agent for the Secured Parties with full and valid authority so to
     act or refrain from acting, and VeraSun shall not be obligated or entitled
     to make any inquiry respecting such authority.

               (c) The Escrow Agent shall have and be entitled to exercise all
     powers hereunder that are specifically granted to the Escrow Agent by the
     terms hereof, together with such powers as are reasonably incident thereto
     but no duties, obligations or powers shall be inferred or implied. The
     Escrow Agent may perform any of its duties hereunder or in connection with
     the Collateral by or through agents, attorneys, experts, accountants,
     advisors or employees and the exculpatory provisions provided herein shall
     be equally applicable to such Persons. The Escrow Agent shall be entitled
     to retain counsel and to act in reliance upon the advice of counsel
     concerning any matters arising hereunder. Except as otherwise expressly
     provided in this Agreement or the Indenture, neither the Escrow Agent nor
     any director, officer, employee, attorney or agent of the Escrow Agent
     shall be liable to VeraSun for any action taken or omitted to be taken by
     the Escrow Agent, in its capacity as Escrow Agent, hereunder, except for
     its own bad faith, gross negligence or willful misconduct. The Escrow Agent
     and its directors, officers, employees, attorneys and agents shall be
     entitled to conclusively rely on any communication, instrument or document
     (whether in its original or facsimile form) believed by it or them to be
     genuine and correct and to have been signed or sent by the proper person or
     persons.

               (d) The Escrow Agent shall be conclusively presumed to be acting
     as agent for the Secured Parties with full and valid authority so to act or
     refrain from acting, and VeraSun shall not be obligated or entitled to make
     any inquiry respecting such authority.

               13.11 Removal of Escrow Agent and Securities Intermediary;
Successor Escrow Agent and Securities Intermediary by Merger, etc. (a) VeraSun
and the Trustee may remove both the Escrow Agent and the Securities Intermediary
at any time by giving to the Escrow Agent and the Securities Intermediary thirty
calendar days' prior notice in writing signed by both VeraSun and the Trustee.

               (b) Within twenty calendar days after giving the foregoing notice
     of removal to the Escrow Agent and the Securities Intermediary, VeraSun and
     the Trustee shall jointly agree on and appoint a successor Escrow Agent and
     Securities Intermediary. If a successor Escrow Agent has not accepted such
     appointment by the end of such

<PAGE>

     twenty-day period, the Escrow Agent and Securities Intermediary may, in
     their sole discretion, apply to a court of competent jurisdiction for the
     appointment of a successor Escrow Agent and Securities Intermediary or for
     other appropriate relief.

               (c) Upon receipt of the notice of identity of the successor
     Escrow Agent, the Escrow Agent shall deliver the Collateral then held
     hereunder to the successor Escrow Agent.

               (d) If the Escrow Agent consolidates, merges or converts into, or
     transfers all or substantially all of its corporate trust business to,
     another corporation, the successor corporation without any further act
     shall be the successor Escrow Agent.

               13.12 Resignation. The Escrow Agent may resign hereunder upon
sixty (60) days' prior notice to the VeraSun and Trustee. Upon the effective
date of such resignation, the Escrow Agent shall deliver the Collateral to any
substitute escrow agent designated by VeraSun and Trustee in writing. If VeraSun
and Trustee fail to designate a substitute escrow agent within sixty (60) days
after the giving of such notice, the Escrow Agent may institute a petition for
interpleader. The Escrow Agent's sole responsibility after such 60-day notice
period expires shall be to hold the Deposit (without any obligation to reinvest
the same) and to deliver the same to a designated substitute escrow agent, if
any, or in accordance with the directions of a final order or judgment of a
court of competent jurisdiction, at which time of delivery the Escrow Agent's
obligations hereunder shall cease and terminate.

               13.13 Tax Matters. Each of VeraSun and the Trustee and the
Collateral Agent shall provide the Escrow Agent with its taxpayer identification
number documented on the signature page hereto. Failure so to provide such forms
may prevent or delay disbursements from the Collateral and may also result in
the assessment of a penalty and Escrow Agent's being required to withhold tax on
any interest or other income earned on the Collateral. Any payments of income
shall be subject to applicable withholding regulations then in force in the
United States or any other jurisdiction, as applicable.

               13.14 Funds Transfer. (a) In the event funds transfer
instructions are given (other than in writing at the time of execution of the
Escrow Agreement), whether in writing, by telefax, or otherwise, the Escrow
Agent is authorized to seek confirmation of such instructions by telephone
call-back to the person or person designated on Schedule II hereto, and the
Escrow Agent may rely upon the confirmations of anyone purporting to be the
person or persons so designated. If the Escrow Agent is unable to contact any of
the authorized representatives identified in Schedule II, the Escrow Agent is
hereby authorized to seek confirmation of such instructions by telephone
call-back to any one or more of your Officers, as the Escrow Agent may select.
Such Officer shall deliver to the Escrow Agent a fully executed Incumbency
Certificate, and the Escrow Agent may rely upon the confirmation of anyone
purporting to be any such Officer. The persons and telephone numbers for
call-backs may be changed only in writing actually received and acknowledged by
the Escrow Agent. The parties to this Escrow Agreement acknowledge that such
security procedure is commercially reasonable.

               (b) It is understood that the Escrow Agent and the beneficiary's
     bank in any funds transfer may rely solely upon any account numbers or
     similar identifying

<PAGE>

     number provided by either of the other parties hereto to identify (i) the
     beneficiary, (ii) the beneficiary's bank, or (iii) an intermediary bank.
     The Escrow Agent may apply any of the escrowed funds for any payment order
     it executes using any such identifying number, even where its use may
     result in a person other than the beneficiary being paid, or the transfer
     of funds to a bank other than the beneficiary's bank or an intermediary
     bank, designated.

               13.15 Final Expression. This Agreement, together with the
Indenture and any other agreement executed in connection herewith, is intended
by the parties as a final expression of this Agreement and is intended as a
complete and exclusive statement of the terms and conditions thereof.

               13.16 Rights of Holders of the Notes. No Holder of Notes shall
have any independent rights hereunder other than those rights granted to
individual Holders of the Notes pursuant to Article 6 of the Indenture; provided
that nothing in this subsection shall limit any rights granted to the Trustee
under the Notes or the Indenture.

               13.17 Governing Law; Submission to Jurisdiction; Waiver of Jury
Trial; Waiver of Damages. (a) This Agreement shall be governed by and
interpreted in accordance with the laws of the State of New York, and any
dispute arising out of, connected with, related to, or incidental to the
relationship established between VeraSun, the Trustee, the Escrow Agent, the
Collateral Agent, the Securities Intermediary, and the Holders of the Notes in
connection with this Agreement, and whether arising in contract, tort, equity or
otherwise, shall be resolved in accordance with the laws of the State of New
York.

               (b) VeraSun hereby waives personal service of process in any
     suit, action or proceeding with respect to this Agreement and for actions
     brought under the U.S. Federal or state securities laws brought in any
     Federal or state court located in the City of New York (each a "NEW YORK
     COURT") and consents that all service of process in any such suit, action
     or proceeding shall be made by registered mail, return receipt requested,
     directed to VeraSun at the address indicated in Section 13.1. Each of the
     parties hereto submits to the jurisdiction of any New York Court and to the
     courts of its corporate domicile with respect to any actions brought
     against it as defendant in any suit, action or proceeding arising out of,
     connected with, related to, or incidental to the relationship established
     among VeraSun, the Trustee, the Collateral Agent, the Securities
     Intermediary, the Escrow Agent and the Holders in connection with this
     Agreement, and each of the parties hereto waives any objection that it may
     have to the laying of venue, including any pleading of forum non
     conveniens, with respect to any such action and waives any right to which
     it may be entitled on account of place of residence or domicile.

               (c) VeraSun agrees that neither any Holder of Notes nor (except
     as otherwise provided in this Agreement or the Indenture) the Escrow Agent
     in its capacity as Escrow Agent nor the Securities Intermediary nor the
     Collateral Agent shall have any liability to VeraSun (whether arising in
     tort, contract or otherwise) for losses suffered by VeraSun in connection
     with, arising out of, or in any way related to, the transactions
     contemplated and the relationship established by this Agreement, or any
     act, omission or event occurring in connection therewith, unless such
     losses were the result of acts or

<PAGE>

     omissions on the part of the Escrow Agent, the Securities Intermediary, or
     the Collateral Agent or such Holders of Notes, as the case may be,
     constituting bad faith, gross negligence or willful misconduct.

                     [REMAINDER OF PAGE INTENTIONALLY BLANK]

<PAGE>

          IN WITNESS WHEREOF, the parties hereto have each caused this Agreement
to be duly executed and delivered as of the date first above written.

          SECTION 3.04. Insurance. Grantor shall:(a) Keep, at its sole cost and
expense, the Mortgaged Property insured at all times in such amounts as shall be
customary for similar businesses as Grantor's business and maintain such other
insurance of such types, to such extent and against such risks, as is customary
with companies in the same or similar businesses as Grantor's business and
maintain such other insurance as may be required by law or the terms of the
Indenture. Without limiting the generality of the foregoing Grantor shall
maintain the following insurance coverage:

          (1) All Risk Property insurance on the Premises, including contingent
     liability from Operation of Building Laws, Demolition Costs and Increased
     Cost of Construction endorsements, in each case (i) in an amount equal to
     100% of the "Full Replacement Cost" of the Premises, which for purposes of
     this Section shall mean actual replacement value (exclusive of costs of
     excavations, foundations, underground utilities and footings) with a waiver
     of depreciation and with a Replacement Cost Endorsement, subject to
     commercially reasonable sub-limits; (ii) containing an agreed amount
     endorsement with respect to the Premises waiving all co-insurance
     provisions; (iii) providing for no deductible in excess of $1,000,000; and
     (iv) containing an "Ordinance or Law Coverage" or "Enforcement" endorsement
     if any of the Improvements or the use of the Premises shall constitute
     non-conforming structures or uses. The Full Replacement Cost shall be
     determined from time to time by an appraiser or contractor designated and
     paid by Grantor and approved by Mortgagee, which approval shall not be
     unreasonably withheld, delayed or conditioned, or by an engineer or
     appraiser in the regular employ of Grantor. Mortgagee shall not require an
     appraisal more often than once per year unless Mortgagee in its reasonable
     discretion believes that the Full Replacement Cost has increased.

          (2) Commercial General Liability insurance against claims for personal
     injury, bodily injury, death or property damage occurring upon, in or about
     the Property, such insurance (i) to be on the so-called "occurrence" form
     with each occurrence and general aggregate limits of not less than
     $50,000,000 (may be satisfied in combination with umbrella liability
     coverage); (ii) to continue at not less than this limit until required to
     be changed by Mortgagee in writing by reason of changed economic conditions
     making such protection inadequate; and (iii) to cover at least the
     following hazards: (a) premises and operations; (b) products and completed
     operations on an "if any" basis; (c) independent contractors; (d) blanket
     contractual liability for all written contracts; and (e) contractual
     liability covering the indemnities contained in this Mortgage to the extent
     available.

          (3) Workers' Compensation insurance, subject to the statutory limits
     of the State, and employer's liability insurance with a limit of at least
     $1,000,000 per accident and per disease per employee, and $1,000,000 for
     disease in the aggregate in respect of any work or operations on or about
     the Premises, or in connection with the Premises or its operations (if
     applicable).

          (4) Boiler & Machinery insurance covering the major components of the
     central heating, air conditioning and ventilating systems, boilers, other
     pressure vessels, high pressure piping and machinery, elevators and
     escalators, if any, and other similar equipment installed in the
     Improvements, in an amount equal to the lesser of (i) one hundred percent
     (100%) of the full replacement cost of all equipment installed in, on or at


                                        8

<PAGE>

     the Improvements and (ii) a minimum of $100,000,000 in coverage. These
     policies shall insure against physical damage to and loss of occupancy and
     use of the Improvements arising out of a covered accident or breakdown.

          (5) To the extent available at commercially reasonable rates,
     terrorism Insurance from and against all losses, damages, costs, expenses,
     claims and liabilities relating to or arising from acts of terrorism in an
     amount equal to the "Full Replacement Cost" of the Improvements as
     determined above.

          (6) If Mortgagee determines at any time that any part of the Premises
     is located in an area identified on a Flood Hazard Boundary Map or Flood
     Insurance Rate Map issued by the Federal Emergency Management Agency as
     having special flood hazards and flood insurance has been made available,
     Grantor will maintain a flood insurance policy meeting the requirements of
     the current guidelines of the Federal Insurance Administration with a
     generally acceptable insurance carrier, in an amount not less than the
     lesser of (i) the outstanding principal balance of the Indebtedness or (ii)
     the maximum amount of insurance which is available under the National Flood
     Insurance Act of 1968, the Flood Disaster Protection Act of 1973 or the
     National Flood Insurance Reform Act of 1994, as amended.

          (7) During the period of any construction or renovation or alteration
     of the Improvements, a so-called "Builder's All Risk" insurance policy in
     non-reporting form for any Improvements under construction, renovation or
     alteration including, without limitation, for demolition and increased cost
     of construction or renovation, in an amount approved by Mortgagee, which
     approval shall not be unreasonably withheld, delayed or conditioned,
     including an Occupancy endorsement and Worker's Compensation Insurance
     covering all Persons engaged in the construction, renovation or alteration
     in an amount at least equal to the minimum required by statutory limits of
     the State of [South Dakota][Iowa].

          (8) Such other insurance as may from time to time be reasonably
     required by Mortgagee against other insurable hazards, provided that such
     other insurance is customarily maintained by companies in the same or
     similar businesses as Grantor's business.

     (b) Cause all such property and casualty insurance policies with respect to
the Mortgaged Property to be endorsed or otherwise amended to include a
"standard" or "New York" lender's loss payable endorsement, in form and
substance reasonably satisfactory to the Mortgagee, which endorsement shall
provide that, from and after the date hereof, if the insurance carrier shall
have received written notice from the Mortgagee of the occurrence of an Event of
Default and such Event of Default should be continuing, the insurance carrier
shall pay all proceeds otherwise payable to Grantor under such policies directly
to the Mortgagee; cause all such policies to provide that neither Grantor,
Mortgagee nor any other Person shall be a coinsurer thereunder and to contain a
"Replacement Cost Endorsement," without any deduction for depreciation, and such
other provisions as the Mortgagee may reasonably require from time to time to
protect its interests; deliver original or certified copies of all such policies
or a certificate of an insurance broker to the Mortgagee; cause each such policy
to provide that it shall


                                        9

<PAGE>

not be canceled or not renewed upon less than 30 days' prior written notice
thereof by the Mortgagee; deliver to the Mortgagee, prior to the cancellation or
nonrenewal of any such policy of insurance, a copy of a renewal or replacement
policy (or other evidence of renewal of a policy previously delivered to the
Mortgagee), or insurance certificate with respect thereto, together with
evidence reasonably satisfactory to the Mortgagee of payment of the premium
therefor. Grantor's insurance shall be primary and without contribution from any
insurance procured by Mortgagee. All the insurance companies must be authorized
to do business in the State of [South Dakota][Iowa]. The primary property and
liability insurance companies must have a general policy rating of A or better
and a financial class of X or better by A.M. Best Company, Inc. and a claims
paying ability of BBB or better according to Standard & Poors.

     (c) In the event Grantor satisfies the requirements hereunder through the
use of a blanket policy covering properties in addition to the Mortgaged
Property, then (unless such policy is provided in substantially the same manner
as it is as of the date hereof), Grantor shall provide evidence satisfactory to
Mortgagee that the insurance premiums for the Mortgaged Property are separately
allocated under such policy to the Mortgaged Property and that payment of such
allocated amount (i) shall maintain the effectiveness of such policy as to the
Mortgaged Property and (ii) shall otherwise provide the same protection as would
a separate policy that complies with the terms of this Mortgage as to the
Mortgaged Property, notwithstanding the failure of payment of any other portion
of the insurance premiums. If no such allocation is available, Mortgagee may,
upon not less than 30 days' prior written notice to Grantor (unless Grantor or
the insurer furnishes to Mortgagee assurance reasonably satisfactory to
Mortgagee that the failure to have such allocation would not reasonably be
expected to have a material adverse affect on the coverage available with
respect to the Premises as required by this Mortgage or Mortgagee's ability to
provide such insurance should Grantor fail to do so), purchase a non-blanket
policy covering such Mortgaged Property from insurance companies which qualify
under this Mortgage and at Grantor's cost and Grantor shall reimburse Mortgagee
upon demand and such amount shall incur interest at the Default Rate from and
including the date paid by Mortgagee until repaid to Mortgagee in full.

          SECTION 3.05. Liens and Liabilities.

     (a) Discharge of Liens. Grantor will pay, bond or otherwise discharge, from
time to time when the same shall become due, all claims and demands of
mechanics, materialmen, laborers and others which, if unpaid, might result in,
or permit the creation of, a lien on the Premises except to the extent the same
are not yet delinquent or being contested in accordance with Section 3.13 in
good faith by appropriate legal proceedings promptly instituted and diligently
conducted and for which a reserve or other appropriate provision, if any, as
shall be required in conformity with GAAP shall have been made.

     (b) Creation of Liens. (i) Grantor will not, without Mortgagee's consent,
create, place or permit to be created or placed or allow to remain, and (subject
to the right of Mortgagee to contest the same in accordance with Section 3.13 in
good faith by appropriate legal proceedings promptly instituted and diligently
conducted and for which a reserve or other appropriate provision, if any, as
shall be required in conformity with GAAP shall have been made) shall discharge
and release (A) within sixty (60) days of the placing thereof, any deed of
trust, mortgage, trust deed, voluntary lien, security interest or other
encumbrance and (B) within


                                       10

<PAGE>

sixty (60) days after receipt of written notice thereof, any involuntary lien,
security interest or other encumbrance (and, in any event, in the case of any
such lien or encumbrance described in Clause (A) and (B) hereof, at such earlier
time as may be required to prevent (1) foreclosure of such lien or encumbrance
and (2) any liability to Mortgagee or Secured Parties in respect thereof)
against or covering the Premises, other than Permitted Encumbrances, whether or
not subordinate hereto.(ii) Grantor shall have the right to grant easements,
rights of way and similar rights ("EASEMENTS") affecting the Premises or any
part thereof for the purpose of providing water, gas, electric, power, sewer,
drainage, telephone, telecommunication and other utilities, facilities and
services to the Premises or any premises adjacent to the Premises or for the
purpose of providing access, ingress, egress, roads, railroad spurs, parking and
similar facilities and rights serving the Premises or any premises adjacent to
the Premises, provided that any such Easement does not materially adversely
affect the use of the Premises or the value of the Premises at such time. Any
such Easements granted by Grantor shall be Permitted Encumbrances. Upon the
request of Grantor, Mortgagee shall (at Grantor's sole cost and expense)
promptly execute and deliver an instrument in form and substance reasonably
satisfactory to Grantor and Mortgagee providing that this Mortgage shall be
subject and subordinate to any such Easement, provided that (x) Grantor shall
deliver to Mortgagee an Officer's Certificate that such Easement does not
materially adversely affect the use of the Premises or the value of the Premises
at the time and (y) if the Grantor receives any cash consideration for such
Easement, Grantor shall deliver to Mortgagee such cash consideration, which
Mortgagee shall deposit in the Collateral Account and hold, apply and pay the
same as provided in the Indenture. Grantor shall also have the right to release
Easements benefiting the Premises and, upon the request of Grantor, Mortgagee
shall (at Grantor's sole cost and expense) promptly execute and deliver an
instrument in form and substance reasonably satisfactory to Grantor and
Mortgagee providing that the relevant Easement shall be and thereby is released
from the lien of this Mortgage, provided that (X) Grantor shall deliver to
Mortgagee an Officer's Certificate that the release of such Easement does not
materially adversely affect the use or value of the Premises at the time and (Y)
if Grantor receives any cash consideration for such release, Grantor shall
deliver to Mortgagee such cash consideration, which Mortgagee shall deposit in
the Collateral Account and hold, apply and pay the same as provided in the
Indenture.

     (c) No Consent. Nothing in this Mortgage shall be deemed or construed in
any way as constituting the consent or request by Mortgagee, express or implied,
to any contractor, subcontractor, laborer, mechanic or materialman for the
performance of any labor or the furnishing of any material for any improvement,
construction, alteration or repair of the Premises. Grantor further agrees that
Mortgagee does not stand in any fiduciary relationship to Grantor.

          SECTION 3.06. Taxes and Other Charges.

     (a) Taxes on the Premises. Grantor will promptly pay when due and before
any penalty or interest may be added thereto, all Impositions. Grantor will also
pay any penalty, interest or cost for non-payment of Impositions which may
become due and payable except to the extent the same are not yet delinquent or
being contested in accordance with Section 3.13 in good faith by appropriate
legal proceedings promptly instituted and diligently conducted and for which a
reserve or other appropriate provision, if any, as shall be required in
conformity with GAAP shall have been made.


                                       11

<PAGE>

     Increased Costs. In the event of the enactment after the date hereof of any
law or regulation deducting from the value of the Mortgaged Property for the
purpose of taxation any lien or security interest thereon, or changing in any
way the laws for the taxation of mortgages, deeds of trust or other liens or
debts secured thereby, or the manner of collection of such taxes, so as to
adversely affect (other than to a de minimis extent with respect to non-monetary
obligations only) this Mortgage, the Secured Obligations, Mortgagee or the
Secured Parties, then, and in such event, Grantor shall, on demand, pay to
Mortgagee or such Secured Parties, or reimburse Mortgagee or such Secured
Parties for payment of, all taxes, assessments, charges or liens for which
Mortgagee or such Secured Parties are or may be liable as a result thereof,
provided that if any such payment or reimbursement shall be unlawful or would
constitute usury or render the Secured Obligations wholly or partially usurious
under applicable law, then Mortgagee may, at its option, require Grantor to pay
or reimburse Mortgagee for payment of the lawful and non-usurious portion
thereof.

          SECTION 3.07. Damage and Destruction.

          (a) Grantor's Obligations. In the event of any damage to or loss or
destruction of the Premises, Grantor shall (i) promptly notify Mortgagee of such
event, if such event would give rise to a claim under the insurance policies
required to be maintained by Grantor pursuant to Section 3.04, (ii) take such
steps as shall be reasonably necessary to preserve any undamaged portion of the
Premises and (iii) take such steps as shall be reasonable necessary to recover
and apply the Net Loss Proceeds in connection with such damage or destruction in
accordance with the terms of the Indenture, including depositing such Net Loss
Proceeds into the Collateral Account.

          (b) Mortgagee's Rights; Application of Proceeds. In the event that any
portion of the Premises is so damaged, destroyed or lost, and such damage,
destruction or loss is covered, in whole or in part, by insurance required by
Section 3.04, then (i) Mortgagee may, but shall not be obligated to, make proof
of loss if an Event of Default shall have occurred and be continuing and is
hereby authorized and empowered by Grantor to settle, adjust or compromise any
claims for damage, destruction or loss thereunder if an Event of Default shall
have occurred and be continuing and (ii) each insurance company concerned is
hereby authorized and directed to make payment therefor directly to Mortgagee if
an Event of Default shall have occurred and be continuing. Mortgagee shall
deposit in the Collateral Account any Net Loss Proceeds that it recovers for
application in accordance with the terms of the Indenture.

          (c) Repairs and Restoration. Notwithstanding anything to the contrary,
except as provided in the Indenture, Grantor shall have no obligation to restore
the Premises or, if Grantor elects to restore the Premises, to expend any sum in
excess of the Net Loss Proceeds made available to Grantor for such purpose
pursuant to the Indenture.

          (d) Effect on the Secured Obligations. Notwithstanding any loss,
damage or destruction referred to in this Section, Grantor shall continue to be
obligated on the Secured Obligations as provided herein, except to the extent
that the Net Loss Proceeds are applied to the Secured Obligations. Any reduction
in the Secured Obligations resulting from such application shall be deemed to
take effect only on the date of receipt by Mortgagee of such insurance proceeds
and application against the Secured Obligations, provided that if prior to the
receipt by


                                       12

<PAGE>

Mortgagee of such insurance proceeds the Mortgaged Property shall have been sold
on foreclosure of this Mortgage or by exercise of the power of sale hereunder,
or shall have been transferred by deed in lieu of foreclosure of this Mortgage,
Mortgagee shall have the right to receive the same to the extent of any
deficiency found to be due upon such sale, with legal interest thereon together
with attorneys' fees and disbursements incurred by Mortgagee in connection with
the collection thereof.

          SECTION 3.08. Condemnation.

          (a) Grantor's Obligations; Proceedings. Grantor, promptly upon
obtaining knowledge of any pending or threatened institution of any proceedings
for the condemnation of the Premises, or of any right of eminent domain which
would materially adversely affect the use and operation of the Premises as
required hereunder, will notify Mortgagee of the threat or pendency thereof. If
an Event of Default shall have occurred and be continuing, Mortgagee may
participate in any such proceedings, and Grantor from time to time will execute
and deliver to Mortgagee all instruments requested by Mortgagee or as may be
required to permit such participation. Grantor shall, at its expense, diligently
prosecute any such proceedings, and, if an Event of Default shall have occurred
and be continuing, (i) shall deliver to Mortgagee copies of all papers served in
connection therewith and shall consult and cooperate with Mortgagee, its
attorneys and agents, in the carrying on and defense of any such proceedings and
(ii) shall not adjust, settle or compromise any such proceedings without
Mortgagee's consent. Grantor shall recover and apply the Net Loss Proceeds in
connection with any condemnation or eminent domain or deed in lieu thereof in
accordance with the terms of the Indenture, including depositing such Net Loss
Proceeds into the Collateral Account.

          (b) Mortgagee's Rights; Application of Awards. Mortgagee may, but
shall not be obligated to, adjust, settle or compromise any claim or proceeding
in connection with a condemnation or eminent domain if an Event of Default shall
have occurred and be continuing and Mortgagee is hereby authorized and empowered
by Grantor to settle, adjust or compromise any such claim or proceeding if an
Event of Default shall have occurred and be continuing. Mortgagee shall deposit
in the Collateral Account any Net Loss Proceeds that it recovers for application
in accordance with the terms of the Indenture.

          (c) Repairs and Restoration. Notwithstanding anything to the contrary,
except as provided in the Indenture, Grantor shall have no obligation to restore
the Premises or, if Grantor elects to restore the Premises, to expend any sum in
excess of the Net Loss Proceeds made available to Grantor for such purpose
pursuant to the Indenture.

          (d) Effect on the Secured Obligations. Notwithstanding any
condemnation, taking or other proceeding referred to in this Section, Grantor
shall continue to be obligated on the Secured Obligations as provided herein,
except to the extent that the Net Loss Proceeds are applied to the Secured
Obligations. Any reduction in the Secured Obligations resulting from such
application shall be deemed to take effect only on the date of receipt by
Mortgagee of such Awards and application against the Secured Obligations,
provided that if prior to the receipt by Mortgagee of such Awards the Mortgaged
Property shall have been sold on foreclosure of this Mortgage or the exercise of
the power of sale hereunder, or shall have been transferred by deed in lieu of
foreclosure of this Mortgage, Mortgagee shall have the right to receive the same
to the


                                       13

<PAGE>

extent of any deficiency found to be due upon such sale, with legal interest
thereon together with attorneys' fees and disbursements incurred by Mortgagee in
connection with the collection thereof.

          SECTION 3.09. Notice Limiting Amount. Grantor covenants that it will
not, without the prior written consent of Mortgagee, file of record any notice
limiting the maximum principal amount secured by this Mortgage.

          SECTION 3.10. Permits. Grantor has and will maintain all required
certificates, licenses, authorizations, registrations, permits and/or approvals
for the operation, use and occupancy of the Premises, and the conduct of
Grantor's business at the Premises (except where such failure to maintain would
not reasonably be expected to have a material adverse effect on the operation of
Grantor's business or the operation, use or occupancy of the Premises) and,
promptly upon request by Mortgagee, Grantor shall deliver to Mortgagee copies of
all of the same.

          SECTION 3.11. Further Assurances. Grantor shall:

          (i) at Grantor's sole cost and expense and at the reasonable request
of Mortgagee, (A) promptly correct any defect or error which may be discovered
in the contents of this Mortgage or in its execution, acknowledgment or
recordation and (B) promptly do, execute, acknowledge and deliver any and all
such further acts, deeds, conveyances, mortgages, deeds of trust, trust deeds,
assignments, estoppel certificates, financing statements and continuations
thereof, notices of assignment, transfers, certificates, assurances and other
instruments that may be necessary or that Mortgagee may reasonably request from
time to time in order to carry out more effectively the purposes of this
Mortgage, to subject to the lien and security interest hereby created any of
Grantor's properties, rights or interests covered or now or hereafter intended
to be covered hereby, to perfect and maintain said lien and security interest,
and to better assure, convey, grant, assign, transfer and confirm unto Mortgagee
the rights granted or now or hereafter intended to be granted to Mortgagee
hereunder or under any other instrument executed in connection with this
Mortgage or which Grantor may be or become bound to convey, mortgage or assign
to Mortgagee in order to carry out the intention or facilitate the performance
of the provisions of this Mortgage; and

          (ii) at the request of Mortgagee, promptly record and re-record, file
and refile and register and re-register this Mortgage, any financing or
continuation statements and every other instrument in addition or supplemental
to any thereof that shall be required by any present or future law in order to
perfect and maintain the validity, effectiveness and priority of this Mortgage
and the lien and security interest intended to be created hereby, or to subject
after-acquired property of Grantor to such lien and security interest, in such
manner and places and within such times as may be necessary to accomplish such
purposes and to preserve and protect the rights and remedies of Mortgagee. Upon
any failure by Grantor to do so after such request by Mortgagee, Mortgagee may
make, execute, record, file, re-record or refile any and all such mortgages,
instruments, certificates and documents for and in the name of Grantor, and
Grantor hereby irrevocably appoints Mortgagee the agent and attorney-in-fact of
Grantor to do so, which appointment will terminate upon the satisfaction of
record of this Mortgage. Grantor will furnish to Mortgagee evidence reasonably
satisfactory to Mortgagee of every such


                                       14

<PAGE>

recording, filing or registration. Mortgagee may, at Grantor's sole expense,
file copies or reproductions of this instrument as financing statements at any
time and from time to time without further authorization from Grantor.

          SECTION 3.12. Leases. (a) Assignment. Grantor hereby absolutely and
presently bargains, sells, transfers, assigns and sets over to Mortgagee, as
further security for the payment of the Secured Obligations, all of its right,
title and interest in and to the Leases and the Rents payable thereunder and all
rights of Grantor thereunder and any and all deposits held as security under the
Leases, whether before or after foreclosure or during the full period of
redemption, if any, and shall, upon demand, deliver to Mortgagee an executed
counterpart of each Lease. The assignment of the Leases and Rents, and of the
aforesaid rights with respect thereto, is intended to be and is an absolute
present assignment from Grantor to Mortgagee and not merely the passing of a
security interest. Such assignment and grant shall continue in effect until the
Secured Obligations are paid, the execution of this Mortgage constituting and
evidencing the irrevocable consent of Grantor to the entry upon and taking
possession of the Premises by Mortgagee pursuant to such grant, whether
foreclosure has been instituted or not and without applying for a receiver.
Until an Event of Default shall have occurred and be continuing, Grantor shall
be entitled to collect and receive the Rents and apply the same in the conduct
of its business, provided that such right of Grantor to collect and receive said
Rents shall be revoked upon written notice by Mortgagee to Grantor that an Event
of Default has occurred and is continuing, and thereafter Mortgagee shall have
the right and authority to exercise any of the rights or remedies referred to or
set forth in Article VI. In addition, if such an Event of Default shall have
occurred and be continuing, Grantor shall promptly pay to Mortgagee (i) all rent
prepayments and security or other deposits paid to Grantor pursuant to any Lease
assigned hereunder and (ii) all charges for services or facilities or for
escalation which were paid pursuant to any such Lease to the extent allocable to
any period from and after such Event of Default. Nothing contained in this
subsection (a) shall be construed to bind Mortgagee to the performance of any of
the covenants, conditions or provisions contained in any Lease or otherwise to
impose any obligation on Mortgagee (including any liability under the covenant
of quiet enjoyment contained in any Lease or under any applicable law in the
event that any tenant shall have been joined as a party defendant in any action
to foreclose this Mortgage and shall have been barred and foreclosed thereby of
all right, title and interest and equity of redemption in the Premises), except
that Mortgagee shall be accountable for any money actually received pursuant to
such assignment. Grantor hereby further grants to Mortgagee the right to notify
the tenant under any Lease of the assignment thereof and, if an Event of Default
has occurred and is continuing (i) to demand that the tenant under any Lease pay
all amounts due thereunder directly to Mortgagee, (ii) to enter upon and take
possession of the Premises for the purpose of collecting the Rents, (iii) to
dispossess by the usual summary proceedings any tenant defaulting in the payment
thereof, (iv) to let the Premises, or any part thereof, and (v) to apply the
Rents, after payment of all necessary charges and expenses, on account of the
Secured Obligations.

          (b) Grantor's Obligation to Pay Rent. If Grantor is not required to
surrender possession of the Premises hereunder if an Event of Default has
occurred and is continuing, Grantor will pay monthly in advance to Mortgagee, on
its entry into possession pursuant to Article VI, or to any receiver appointed
to collect said Rents, the fair and reasonable rental value for the use and
occupation of the Premises or such part thereof as may be in the possession of
Grantor. Upon a default in any such payment, Grantor will vacate and surrender
such possession


                                       15

to Mortgagee or such receiver, and, in default thereof, may be evicted by
summary or any other available proceedings or actions.

          (c) Separate and Distinct Rights. The security pledged in this Section
constitutes primary collateral for the Secured Obligations on a par with all
other collateral and security provided for in this Mortgage and other agreements
executed in connection with this Mortgage. Without limiting any other provision
of this Mortgage, or other documents regarding the exercise of remedies,
Mortgagee may exercise the rights granted to it in this section separate from or
in conjunction with any other remedies provided for in this Mortgage and other
documents in any order and at such time or times as Mortgagee, at its sole and
absolute discretion, may elect.

          (d) Subordination, Nondisturbance and Attornment Agreements. Upon the
request of Grantor, Mortgagee shall (at Grantor's sole cost and expense)
promptly execute and deliver a subordination, nondisturbance and attornment
agreement in substantially the form of Exhibit B between Mortgagee and the
tenant under any Lease from Grantor of any part of the Premises, provided that
Grantor shall deliver to Mortgagee an Officer's Certificate to the effect that
that such Lease: (i) is made for a fair market rent and upon other market terms
and conditions and (ii) does not materially adversely affect the use of the
remaining Premises for Grantor's business or materially adversely affect the
value of the Premises at the time.

          SECTION 3.13. Permitted Contests by Grantor. Notwithstanding anything
to the contrary herein, Grantor may contest by appropriate legal proceedings
conducted with due diligence, the amount or validity or application, in whole or
in part, of any Impositions or Liens therefor, or any legal requirements or any
insurance requirements, or any Liens of mechanics, suppliers or materialmen or
similar Liens, or any other Liens, affecting the Premises or any part thereof;
provided that (i) no Event of Default is then continuing, (ii) in the case of
any Impositions or Liens therefor, or any Liens of mechanics, suppliers or
materialmen or similar Liens, or any other Liens, such proceedings shall suspend
the collection of any sums payable to satisfy such Impositions or Liens from the
Premises or any part thereof or any interest therein, (iii) such proceeding
shall be permitted under and be conducted in accordance with any applicable
provisions of any other applicable Loan Document to which Grantor is a party and
shall not constitute an Event of Default, (iv) neither the Premises, nor any
part thereof, nor any interest therein would be in imminent danger of being
sold, forfeited or lost by reason of such proceedings, (v) intentionally
omitted, (vi) in the case of an insurance requirement, failure by Grantor to
comply therewith shall not impair the validity of any insurance required to be
maintained by Grantor hereunder or the right to full payment of any claims
thereunder pending the conclusion of such contest, (vii) in the case of any
instrument of record affecting the Premises, the contest or failure to perform
under any such instrument shall not result in the placing of any lien on the
Premises (except if such lien would be removed upon completion of such
proceedings and is contested in accordance with this Section) and (viii)
Mortgagee would not be in danger of any criminal liability, or any civil
liability not contested in accordance with this Section, by reason of such
contest or the failure to pay such Imposition or to comply with such legal
requirement or insurance requirement pending the resolution of such contest. In
the case of any such contest, compliance with the applicable covenant under this
Mortgage shall be suspended until the conclusion of such contest and the
expiration of a reasonable time, but not less than 30 days, to pay the
applicable Imposition or Lien or comply with the applicable legal


                                       16

<PAGE>

requirement or insurance requirement; provided that, if compliance cannot be
effected within such 30-day period, such 30-day period shall be extended for
such period of time as is necessary to effect compliance, provided that Grantor,
within such 30-day period (or if stayed from doing so promptly after such stay
is removed) commences and, thereafter, diligently prosecutes such compliance to
conclusion.

                                   ARTICLE IV

                          Additional Advances; Expenses

          SECTION 4.01. Additional Advances and Disbursements. Grantor agrees
that, if an Event of Default shall have occurred and be continuing, then
Mortgagee shall have the right without notice to Grantor to advance all or any
part of amounts owing or to perform any or all required actions not paid or
performed by Grantor. No such advance or performance shall be deemed to have
cured such default. All sums advanced and all expenses incurred by Mortgagee in
connection with such advances or actions, and all other sums advanced or
expenses incurred by Mortgagee hereunder or under applicable law (whether
required or optional and whether indemnified hereunder or not) shall, subject to
Section 2.01, be part of the Secured Obligations, shall bear interest at the
Default Rate from the date advanced by Mortgagee to and including the date paid
by Grantor and shall be secured by this Mortgage. Grantor hereby appoints
Mortgagee its true and lawful attorney-in-fact to make the payments and effect
the performance contemplated by the aforesaid provisions in the name and on
behalf of Grantor. This appointment, being coupled with an interest, shall be
irrevocable until all of the Secured Obligations shall be fully satisfied, paid
and performed and Mortgagee shall have no further Secured Obligations.

          SECTION 4.02. Other Expenses. Grantor will pay or, on demand,
reimburse Mortgagee for the payment of any and all costs or expenses (including
reasonable attorneys' fees and disbursements) incurred in connection with (i)
any default or Event of Default by Grantor, (ii) the exercise or enforcement by
or on behalf of Mortgagee of any of its rights or of Grantor's obligations under
this Mortgage or (iii) the granting, administration, enforcement and closing of
the transactions contemplated under this Mortgage.

          SECTION 4.03. Interest After Default. If any payment due hereunder is
not paid in full when due, then the same shall bear interest hereunder at the
Default Rate from the date due to and including the date paid and such interest
shall be added to and become a part of the Secured Obligations and shall be
secured hereby.

                                   ARTICLE V

                            Release of Mortgage Lien

          SECTION 5.01. Release of Mortgage Lien. (a) At such time as the
obligations of VeraSun Energy and the Guarantors under the Securities and the
Indenture shall have been defeased or discharged in accordance with Article VIII
of the Indenture, the Mortgaged Property shall be released form the Liens
created by this Mortgage and all rights to the Mortgaged Property shall revert
to Grantor, all without delivery of any instrument or performance of any act


                                       17

<PAGE>

by any party. At the request and sole expense of Grantor, at and after such
termination, Mortgagee shall promptly execute and deliver to Grantor such
releases or documents as Grantor shall reasonably request to effectuate and
evidence such termination and release and shall promptly deliver to or at the
direction of Mortgagor any Mortgaged Property then held by Mortgagee hereunder.

          (b) If any Mortgaged Property shall be sold, transferred or otherwise
disposed of by Grantor in a transaction permitted under the Indenture, then at
the request and sole expense of Grantor, Mortgagee shall promptly execute and
deliver to Grantor such releases or documents as Grantor shall reasonably
request to effectuate and evidence the release of such Mortgaged Property from
the Liens created by this Mortgage and Mortgagee shall promptly deliver to or at
the direction of Grantor any such Mortgaged Property then held by Mortgagee
hereunder.

                                   ARTICLE VI

                              Defaults and Remedies

          SECTION 6.01. Events of Default. Upon acceleration of the Notes
pursuant to the Indenture, all Secured Obligations shall immediately become due
and payable without further notice to Grantor, except as provided expressly in
the Loan Documents.

          SECTION 6.02. Remedies. During the continuance of any one or more
Events of Default, Mortgagee may, in addition to any rights or remedies
available to it hereunder or under the other Loan Documents and to the extent
permitted by applicable law, take such action personally or by its agents or
attorneys, with or without entry, and without notice, demand, presentment or
protest (each and all of which are hereby waived, except as provided expressly
in this Mortgage and the other Loan Documents), as it deems necessary or
advisable to protect and enforce its rights and remedies against Grantor and in
and to the Mortgaged Property, including the following actions, each of which
may be pursued concurrently or otherwise, at such time and in such order as
Mortgagee may determine, in its sole discretion, without impairing or otherwise
affecting its other rights or remedies:

          (a) institute a proceeding or proceedings, judicial or otherwise, for
     the complete or partial foreclosure of this Mortgage under any applicable
     provision of law; or

     interest, claim and demand of Grantor therein, and all rights of redemption
     thereof, at one or more sales, as an entirety or in parcels, with such
     elements of real and/or personal property, and at such time and place and
     upon such terms as may be permitted by applicable law, and in the event of
     a sale, by foreclosure or otherwise, of less than all of the Mortgaged
     Property, this Mortgage shall continue as a lien and security interest on
     the remaining portion of the Mortgaged Property; or

          (c) institute an action, suit or proceeding in equity for the specific
     performance of any of the provisions contained in the Loan Documents; or


                                       18

     liquidator or conservator of the Mortgaged Property, to be vested with the
     fullest powers permitted under applicable law, as a matter of right and
     without regard to, or the necessity to disprove, the adequacy of the
     security for the Secured Obligations or the solvency of Grantor or Borrower
     or any other Person liable for the payment of the Secured Obligations, and
     Grantor, Borrower and each such other Person so liable waives or shall be
     deemed to have waived such necessity and consents or shall be deemed to
     have consented to such appointment; or

          (e) enter upon the Premises, and exclude Grantor and its agents and
     servants wholly therefrom, without liability for trespass, damages or
     otherwise, and take possession of all books, records and accounts relating
     thereto and all other portions of the Premises, and Grantor agrees to
     surrender possession of the Premises and of such books, records and
     accounts to Mortgagee on demand during the continuance of any Event of
     Default; and having and holding the same may use, operate, manage,
     preserve, control and otherwise deal therewith and conduct the business
     thereof, either personally or by its superintendents, managers, agents,
     servants, attorneys or receivers, without interference from Grantor
     (including, without limitation, (i) entering into such contracts and taking
     such other action as Mortgagee deems appropriate to complete any
     construction then in progress on the Land, and in connection with any such
     action Mortgagee may modify plans and specifications as Mortgagee deems
     appropriate; (ii) making, cancelling, enforcing or modifying leases; (iii)
     obtaining and evicting tenants; (iv) fixing or modifying Rents; (v)

     them, in any manner Mortgagee may determine); and upon each such entry and
     from time to time thereafter may, at the expense of Grantor and the
     Mortgaged Property, without interference by Grantor and as Mortgagee may
     deem advisable, (A) insure or reinsure the Premises, (B) make all necessary
     or proper repairs, renewals, replacements, alterations, additions,
     betterments and improvements thereto and thereon and (C) in every such case
     in connection with the foregoing have the right to exercise all rights and
     powers of Grantor with respect to the Premises, either in Grantor's name or
     otherwise; or

          (f) with or without entrance upon the Premises, collect, receive, sue
     for and recover in its own name all Rents and cash collateral derived from
     the Premises, and after deducting therefrom all costs, expenses and

     and in using, operating, managing, preserving and controlling the Premises,
     and otherwise in exercising Mortgagee's rights under subsection (e) of this
     Section, including all amounts necessary to pay Impositions, insurance
     premiums and other charges in connection with the Premises, as well as
     compensation for the services of Mortgagee and their respective attorneys,
     agents and employees, and to apply the remainder as provided in Section
     6.05; or

          (g) release any portion of the Mortgaged Property for such
     consideration as Mortgagee may require without, as to the remainder of the
     Mortgaged Property, in any


                                       19

<PAGE>

     way impairing or affecting the lien or priority of this Mortgage, or
     improving the position of any subordinate lienholder with respect thereto,
     except to the extent that the Secured Obligations shall have been reduced
     by the actual monetary consideration, if any, received by Mortgagee for
     such release and applied to the Secured Obligations, and may accept by
     assignment, pledge or otherwise any other property in place thereof as
     Mortgagee may require without being accountable for so doing to any other
     lienholder; or

          (h) take all actions permitted under the UCC; or

          (i) take any other action, or pursue any other right or remedy, as
     Mortgagee may have under applicable law, and Grantor does hereby grant the
     same to Mortgagee.

          (j) [It is the express intention of the Grantor and Mortgagee that the
     rights, remedies, powers and authorities conferred upon the Mortgagee
     pursuant to this Mortgage shall include all rights, remedies, powers and
     authorities that a mortgagor may confer upon a mortgagee under applicable
     law [South Dakota][Iowa] mortgage foreclosure law, as if they were
     expressly provided for herein. In the event that any provision in this
     Mortgage shall be inconsistent with any provision of [Iowa][South Dakota]
     mortgage foreclosure law, the provisions of [Iowa][South Dakota] mortgage
     foreclosure law 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
     [Iowa][South Dakota] mortgage foreclosure law.][LOCAL COUNSEL TO CONFIRM
     ACCURACY OF PARAGRAPH J]

          (k) Without limiting the generality of the foregoing, all expenses,
     including reasonable attorneys' fees, incurred by Mortgagee to the extent
     reimbursable under Sections [________] and [____________] of the
     [Iowa][South Dakota] mortgage foreclosure law, whether incurred before or
     after any decree or judgment of foreclosure, and whether provided for in
     this Mortgage, shall be added to the Secured Obligations or to the judgment
     of foreclosure. [LOCAL COUNSEL TO CONFIRM ACCURACY OF PARAGRAPH K]

          In the event that Mortgagee shall exercise any of the rights or
remedies set forth in subsections (e) and (f) of this Section, Mortgagee shall
not be deemed to have entered upon or taken possession of the Premises except
upon the exercise of its option to do so, evidenced by its demand or overt act
for such purpose, nor shall it be deemed a beneficiary or mortgagee in
possession by reason of such entry or taking possession absent such demand or
overt act. Mortgagee shall not be liable to account for any action taken
pursuant to any such exercise other than for Rents actually received by
Mortgagee, nor liable for any loss sustained by Grantor resulting from any
failure to let the Premises, or from any other act or omission of Mortgagee
except to the extent such loss is caused by the gross negligence, willful
misconduct or bad faith of Mortgagee.

          SECTION 6.03. Rights Pertaining to Sales. Subject to the provisions or
other requirements of law and except as otherwise provided herein, the following
provisions shall apply to any sale or sales of all or any portion of the
Mortgaged Property under or by virtue of this Article VI, whether made under the
power of sale herein granted or by virtue of judicial proceedings or of a
judgment or decree of foreclosure and sale:


                                       20

<PAGE>

          (a) Mortgagee may conduct any number of sales from time to time. The
     power of sale set forth in Section 6.02(b) hereof shall not be exhausted by
     any one or more such sales as to any part of the Mortgaged Property which
     shall not have been sold, nor by any sale which is not completed or is
     defective in Mortgagee's opinion, until the Secured Obligations shall have
     been paid in full.

          (b) Any sale may be postponed or adjourned by public announcement at
     the time and place appointed for such sale or for such postponed or
     adjourned sale without further notice. Without limiting the foregoing, in
     case Mortgagee shall have proceeded to enforce any right or remedy under
     this Mortgage by receiver, entry or otherwise, and such proceedings have
     been discontinued or abandoned for any such reason or shall have been
     determined adversely to Mortgagee, then in every such case Grantor and
     Mortgagee shall be restored to their former positions and rights hereunder,
     and all rights, powers and remedies of Mortgagee shall continue as if no
     such proceeding had been taken.

          (c) After each sale, Mortgagee or an officer of any court empowered to
     do so shall execute and deliver to the purchaser or purchasers at such sale
     a good and sufficient instrument or instruments granting, conveying,
     assigning and transferring all right, title and interest of Grantor in and
     to the property and rights sold and shall receive the proceeds of said sale
     or sales and apply the same as herein provided. Mortgagee is hereby
     appointed the true and lawful attorney-in-fact of Grantor, which
     appointment is irrevocable and shall be deemed to be coupled with an
     interest, in Grantor's name and stead, to make all necessary conveyances,
     assignments, transfers and deliveries of the property and rights so sold,
     and for that purpose Mortgagee may execute all necessary instruments of
     conveyance, assignment, transfer and delivery, and may substitute one or
     more Persons with like power, Grantor hereby ratifying and confirming all
     that said attorney or such substitute or substitutes shall lawfully do by
     virtue thereof. Nevertheless, Grantor, if requested by Mortgagee, shall
     ratify and confirm any such sale or sales by executing and delivering to
     Mortgagee or such purchaser or purchasers all such instruments as may be
     advisable, in Mortgagee's judgment, for the purposes as may be designated
     in such request.

          (d) Any and all statements of fact or other recitals made in any of
     the instruments referred to in subsection (c) of this Section given by
     Mortgagee as to nonpayment of the Secured Obligations, or as to the
     occurrence of any Event of Default, or as to Mortgagee's having declared
     all or any of the Secured Obligations to be due and payable, or as to the
     request to sell, or as to notice of time, place and terms of sale and of
     the property or rights to be sold having been duly given, or as to any
     other act or thing having been duly done by Grantor or Mortgagee, shall be
     taken as conclusive and binding against all Persons as to evidence of the
     truth of the facts so stated and recited to the extent permitted by
     applicable law. Mortgagee may appoint or delegate any one or more Persons
     as agent to perform any act or acts necessary or incident to any sale so
     held, including the posting of notices and the conduct of sale.

          (e) The receipt of Mortgagee for the purchase money paid at any such
     sale, or the receipt of any other Person authorized to receive the same,
     shall be sufficient discharge therefor to any purchaser of any property or
     rights sold as aforesaid, and no


                                       21

<PAGE>

     such purchaser, or its representatives, grantees or assigns, after paying
     such purchase price and receiving such receipt, shall be bound to see to
     the application of such purchase price or any part thereof upon or for any
     trust or purpose of this Mortgage or, in any manner whatsoever, be
     answerable for any loss, misapplication or nonapplication of any such
     purchase money, or part thereof, or be bound to inquire as to the
     authorization, necessity, expediency or regularity of any such sale.

          (f) Any such sale or sales shall operate to divest all of the estate,
     right, title, interest, claim and demand whatsoever, whether at law or in
     equity, of Grantor in and to the properties and rights so sold, and shall
     be a perpetual bar both at law and in equity against Grantor and any and
     all Persons claiming or who may claim the same, or any part thereof or any
     interest therein, by, through or under Grantor to the fullest extent
     permitted by applicable law.

          (g) Upon any such sale or sales, Mortgagee may bid for and acquire the
     Mortgaged Property so sold and, in lieu of paying cash therefor, may make
     settlement for the purchase price by crediting against payment of the
     Secured Obligations the amount of the bid made therefor, after deducting
     therefrom the expenses of the sale, the cost of any enforcement proceeding
     hereunder, and any other sums which Mortgagee is authorized to deduct under
     the terms hereof, to the extent necessary to satisfy such bid.

          (h) In the event that Grantor, or any Person claiming by, through or
     under Grantor, shall transfer or refuse or fail to surrender possession of
     the Mortgaged Property after any sale thereof, then Grantor, or such
     Person, shall be deemed a tenant at sufferance of the purchaser at such
     sale, subject to eviction by means of forcible entry and unlawful detainer
     proceedings, or subject to any other right or remedy available hereunder or
     under applicable law.

          (i) Upon any such sale, it shall not be necessary for Mortgagee or any
     public officer acting under execution or order of court to have present or
     constructive possession of any of the Mortgaged Property.

          (j) In the event a foreclosure hereunder shall be commenced by
     Mortgagee, Mortgagee may at any time before the sale of the Mortgaged
     Property abandon the sale or foreclosure, and may institute suit for the
     collection of the Secured Obligations and for the enforcement of this
     Mortgage, or in the event that Mortgagee should institute a suit for
     collection of the Secured Obligations, and for the enforcement of this
     Mortgage, Mortgagee may at any time before the entry of final judgment in
     said suit dismiss the same and sell the Mortgaged Property in accordance
     with the provisions of this Mortgage.

          SECTION 6.04. Expenses. In any proceeding, judicial or otherwise, to
foreclose this Mortgage or enforce any other remedy of Mortgagee under the Loan
Documents, at law or in equity, there shall be allowed and included as an
addition to and a part of the Secured Obligations in the decree for sale or
other judgment or decree, subject to Section 2.01, all expenditures and
expenses, including reasonable attorneys' fees, which may be paid or incurred in
connection with the exercise by Mortgagee of any of its rights and remedies
provided or


                                       22

<PAGE>

referred to in Section 6.02, or any comparable provision of any other Loan
Document, together with interest thereon at the Default Rate from the date
advanced to and including the date paid, and the same shall be part of the
Secured Obligations and shall be secured by this Mortgage.

          SECTION 6.05. Application of Proceeds. The purchase money, proceeds or
avails of any sale referred to in Section 6.02, together with any other sums
which may be held by Mortgagee hereunder, whether under the provisions of this
Article VI or otherwise, shall, except as herein expressly provided to the
contrary, to the extent permitted by applicable law, be applied as follows:

          First: To the payment of the costs and expenses of any such sale and
     of any judicial proceeding wherein the same may be made, and of all
     expenses, including reasonable attorneys' fees, liabilities and advances
     made or incurred by Mortgagee hereunder, together with interest thereon at
     the Default Rate from the date advanced to and including the date paid, and
     all Impositions and other charges, except any Impositions or other charges
     subject to which the Mortgaged Property shall have been sold.

          Second: As provided in Section 10.3 of the Indenture.

          SECTION 6.06. Additional Provisions as to Remedies. To the extent
permitted by applicable law: (a) No delay or omission by Mortgagee to exercise
any right or remedy hereunder upon any default or Event of Default shall impair
such exercise, or be construed to be a waiver of any such default or Event of
Default.

          (b) The failure, refusal or waiver (by consent, waiver or otherwise)
of Mortgagee to assert any right or remedy hereunder upon any default or Event
of Default or other occurrence shall not be construed as waiving such right or
remedy upon any other or subsequent default or Event of Default or other
occurrence.

          (c) Mortgagee shall have no obligation to pursue any rights or
remedies it may have under any other agreement prior to pursuing its rights or
remedies hereunder or under the other Loan Documents.

          (d) Acceptance of any payment after the occurrence of any default or
Event of Default shall not be deemed a waiver or a cure of such default or Event
of Default, and acceptance of any payment less than any amount then due shall be
deemed an acceptance on account only.

          (e) In the event that Mortgagee shall have proceeded to enforce any
right or remedy hereunder by foreclosure, sale, entry or otherwise, and such
proceeding shall be discontinued, abandoned or determined adversely for any
reason, then Grantor and Mortgagee shall be restored to their former positions
and rights hereunder with respect to the Mortgaged Property, subject to the lien
hereof.

          (f) Each right of Mortgagee provided for in this Mortgage shall be
cumulative and shall be in addition to every other right provided for in this
Mortgage or now or hereafter existing at law or in equity, by statute or
otherwise, and the exercise by Mortgagee of any one or


                                       23

<PAGE>

more of such rights shall not preclude the simultaneous or later exercise by
Mortgagee of any other such right.

          SECTION 6.07. Waiver of Rights and Defenses. To the full extent
Grantor may lawfully do so, Grantor agrees with Mortgagee as follows:

          (a) Grantor will not, at any time, insist on, plead, claim or take the
     benefit or advantage of any statute or rule of law now or hereafter in
     force providing for any appraisement, valuation, stay, extension,
     moratorium, redemption or reinstatement, or of any statute of limitations,
     and Grantor, for itself and its successors and assigns, and for any and all
     Persons ever claiming an interest in the Mortgaged Property (other than

          Grantor with any provision of the Loan Documents, or consent by
          Mortgagee to the performance by Borrower or Grantor of any action
          which would otherwise be prohibited thereunder, or to the failure by
          Borrower or Grantor to take any action which would otherwise be
          required thereunder; and

               (iv) any agreement or stipulation between Mortgagee and Grantor
          and/or Borrower, or, with or without Grantor's consent, between
          Mortgagee and any subsequent owner or owners of the Mortgaged Property
          or any other security for the Secured Obligations, renewing, extending
          or modifying the time of payment or the terms of the Loan Documents
          (including a modification of any interest rate), and in any such event
          Grantor and Borrower, as the case may be, shall continue to be
          obligated to pay the Secured Obligations at the time and in the manner
          provided in the Loan Documents, as so renewed, extended or modified,
          unless expressly released and discharged by Mortgagee.

          (e) Regardless of consideration, and without the necessity for any
     notice to or consent by the holder of any subordinate lien, encumbrance,
     right, title or interest in or to the Mortgaged Property, Mortgagee may
     release any Person at any time liable for the payment of the Secured
     Obligations or any portion thereof or any part of the security held for the
     Secured Obligations and may extend the time of payment or otherwise modify
     the terms of the Loan Documents, including a modification of the interest
     rates payable on the principal balance of the Indebtedness without in any
     manner impairing or affecting this Mortgage or the lien hereof or the
     priority of this Mortgage, as so extended and modified, as security for the
     Secured Obligations over any such subordinate lien, encumbrance, right,
     title or interest. Mortgagee may resort for the payment of the Secured
     Obligations to any other security held by Mortgagee in such order and
     manner as Mortgagee, in its discretion, may elect. Mortgagee may take or
     cause to be taken action to recover the Secured Obligations, or any portion
     thereof, or to enforce any provision of the Loan Documents without
     prejudice to the right of Mortgagee thereafter to foreclose or enforce or
     cause to be foreclosed or enforced this Mortgage. Mortgagee shall not be
     limited exclusively to the rights and remedies herein stated but shall be
     entitled to every additional right and remedy now or hereafter afforded by
     law or equity. The rights of Mortgagee under this Mortgage shall be
     separate, distinct and cumulative and none shall be given effect to the
     exclusion of the others. No act of Mortgagee shall be construed as an
     election to proceed under any one provision herein to the exclusion of any
     other provision.

          (f) Grantor hereby waives any defense to the recovery by Mortgagee
     hereunder against Grantor or the Mortgaged Property of any deficiency after
     a nonjudicial sale.

this Mortgage, the other Loan Documents and other evidences of the Secured
Obligations may vary from time to time. For purposes of enforcing this Mortgage,
if any of the terms or provisions of this Mortgage, any other Loan Documents or
other evidences of the Secured Obligations are susceptible of being construed as
binding or obligating Grantor or any other Persons or concerns obligated, either
primarily, secondarily or conditionally, for the payment of any debt, whether or
not secured hereby, under any circumstances or contingencies whatsoever, to pay
interest or loan charges in excess of the maximum amounts permitted by
applicable law from time to time, it is agreed that, for purposes of enforcing
this Mortgage, such terms or provisions are a mistake in calculation or wording

obligated in any manner on any such indebtedness, shall ever be required or
obligated under the terms of this Mortgage, to pay interest or loan charges in
excess of the maximum amounts permitted by applicable law from time to time, and
if, for any reason whatsoever, the interest or loan charges paid on the
indebtedness secured by this Mortgage shall exceed the maximum amounts permitted
by applicable law from time to time, then, for purposes of enforcing this
Mortgage, the holder(s) of this Mortgage receiving such excess shall either (at
the option of such holder(s)) refund to the payor or credit against the
principal of the indebtedness evidenced thereby such portion of such interest
and loan charges as may be necessary to cause the interest and loan charges paid
on the indebtedness secured hereby to equal the maximum amounts permitted by
applicable law from time to time, and no more.

          SECTION 7.19. Attorney In Fact. In any instance in which the Mortgagee
is appointed as attorney-in-fact for Grantor or is otherwise authorized to act

nonuse or condition in, on or about the Premises or any part thereof or on the
adjoining sidewalks, curbs, adjacent property or adjacent parking areas, streets
or ways; (iii) performance of any labor or services or the furnishing of any
materials or other property in respect of the Premises or any part thereof; (iv)
any failure of the Premises to be in compliance with any applicable laws; (v)
any and all claims and demands whatsoever which may be asserted against
Mortgagee by reason of any alleged obligations or undertakings on its part to
perform or discharge any of the terms, covenants, or agreements contained in any
Lease; or (f) the payment of any commission, charge or brokerage fee to anyone
which may be payable in connection with the funding of the Indebtedness secured
by this Mortgagee except in each case (x) Losses arising out of a state of facts
that first occurred or otherwise first came into existence after the applicable
Indemnified Party acquired title to the Mortgaged Property through foreclosure,
a deed in lieu thereof or otherwise and (y) Losses arising from the gross
negligence or willful misconduct of the applicable Indemnified Party. Any
amounts payable to Mortgagee by reason of the application of this Section 8.20
shall


                                       30

<PAGE>

become immediately due and payable and shall bear interest at the Default Rate
from the date same are paid by Mortgagee until repaid by Grantor. The term
"LOSSES" shall mean any and all claims, suits, liabilities (including, without
limitation, strict liabilities), actions, proceedings, obligations, debts,
damages, losses, costs, expenses, fines, penalties, charges, fees, judgments,
awards, amounts paid in settlement of whatever kind or nature (including but not
limited to reasonable legal fees and other out-of-pocket costs of defense). The
term "INDEMNIFIED PARTIES" shall mean (A) Mortgagee and (B) any other Secured
Party and (C) the successors and assigns of any and all of the foregoing in such
capacities.

          (b) Grantor shall, at its sole cost and expense, protect, defend,
indemnify, release and hold harmless the Indemnified Parties from and against
any and all Losses imposed upon or incurred by or asserted against any
Indemnified Parties and directly or indirectly arising out of or in any way
relating to any tax on the making and/or recording of any of the Loan Documents.

          (c) Grantor shall defend the Indemnified Parties by attorneys and
other professionals selected by Grantor subject to the approval of Mortgagee
(such approval not to be unreasonably withheld, delayed or conditioned). Each
Indemnified Party shall give notice to Grantor of any Loss to be indemnified by
Grantor hereunder promptly after such Indemnified Party receives notice or
becomes aware of such Loss, but a failure to do so shall not affect any
Indemnified Party's rights and benefits set forth in this Section 8.20.

stock or other securities of such Subsidiary shall automatically be deemed not
to be part of the "Collateral", but only to the extent necessary to not be
subject to such requirement.

Securities as if it were the absolute owner thereof (including, without
limitation, the right to exchange at its discretion any and all of the Pledged
Securities upon the merger, consolidation, reorganization, recapitalization or
other fundamental change in the corporate structure of any Issuer, or upon the
exercise by the applicable Grantor or the Joint Collateral Agent of any right,
privilege or option pertaining to such Pledged Securities, and in connection
therewith, the right to deposit and deliver any and all of the Pledged
Securities with any committee, depositary, transfer agent, registrar or other
designated agency upon such terms and conditions as the Joint Collateral Agent
may determine), all without liability except to account for property actually
received by it, but the Joint Collateral Agent and the other Secured Parties
shall have no duty to any Grantor to exercise any such right, privilege or
option and shall not be responsible for any failure to do so or delay in so
doing.

          (c) Each Grantor hereby authorizes and instructs each Issuer of
Pledged Securities pledged by such Grantor hereunder to (i) comply with any
instruction received by such Issuer from the Joint Collateral Agent in writing,
without any other or further instructions from such Grantor, and such Grantor
agrees that each Issuer shall be fully protected in so complying, and (ii) pay
any dividends or other payments with respect to the Pledged Securities directly
to the Joint Collateral Agent.

          (d) The Joint Collateral Agent agrees that it shall not give any
instruction described in Section 5.1(c) unless (1) an Event of Default under and
as defined in the Indenture has occurred and is continuing and (2) such
instructions are otherwise in accordance with the terms of the Indenture and
Security Agreement.

     SECTION 5.2 APPLICATION OF PROCEEDS. At any time after the occurrence and
during the continuance of an Event of Default, at the Joint Collateral Agent's
election, the Joint Collateral Agent may apply all or any part of Proceeds,
including, without limitation, any such Proceeds held in the Blocked Account as
set forth below:

          (a) first, to amounts owing to the Joint Collateral Agent and the
Escrow Agent in their respective capacities as Joint Collateral Agent and Escrow
Agent;

          (b) second, to amounts owing to the Trustee in its capacity as such in
accordance with the terms of the Indenture;

          (c) third, all escrowed funds in the Escrow Account to Holders ratably
in accordance with the principal of, and interest and premium, if any,
outstanding on the Notes;

          (d) fourth, Equally and Ratably in accordance with the terms of the
Indenture; and


                                       16

<PAGE>

          (e) fifth, to the Company and/or other persons entitled thereto.

     SECTION 5.3 UCC AND OTHER REMEDIES. If an Event of Default shall occur and
be continuing, the Joint Collateral Agent, on behalf of the Secured Parties, may
exercise, in addition to all other rights and remedies granted to them in this
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Notes, all rights and remedies of a secured party under the UCC
or any other applicable law. Without limiting the generality of the foregoing,
the Joint Collateral Agent, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind, including, without
limitation, notice of intent to accelerate or notice of acceleration, (except
any notice required by law as referred to below) to or upon the Grantor or any
other Person (all and each of which demands, defenses, advertisements and
notices are hereby waived), may in such circumstances forthwith collect,
receive, appropriate and realize upon the Collateral, or any part thereof,
and/or may forthwith sell, lease, assign, give option or options to purchase, or
otherwise dispose of and deliver the Collateral or any part thereof (or contract
to do any of the foregoing), in one or more parcels at public or private sale or
sales, at any exchange, broker's board or office of the Joint Collateral Agent
or elsewhere upon such terms and conditions as it may deem advisable and at such
prices as it may deem best, for cash or on credit or for future delivery without
assumption of any credit risk. The Joint Collateral Agent shall have the right
upon any such public sale or sales, and, to the extent permitted by law, upon
any such private sale or sales, to purchase the whole or any part of the
Collateral so sold, free of any right or equity of redemption in any Grantor,
which right or equity is hereby waived and released. Each Grantor further
agrees, at the Joint Collateral Agent's request, to assemble the Collateral and
make it available to the Joint Collateral Agent at places which the Joint
Collateral Agent shall reasonably select, whether at such Grantor's premises or
elsewhere. The Joint Collateral Agent shall apply the net proceeds of any action
taken by it pursuant to this Section 5.3, after deducting all reasonable costs
and expenses of every kind incurred in connection therewith or incidental to the
care or safekeeping of any of the Collateral or in any way relating to the
Collateral or the rights of the Joint Collateral Agent hereunder, including,
without limitation, reasonable attorneys' fees and disbursements, to the payment
in whole or in part of the Notes and to any other Person legally entitled
thereto in accordance with the terms of the Indenture. To the extent permitted
by applicable law, each Grantor waives all claims, damages and demands it may
acquire against the Joint Collateral Agent or any other Secured Party arising
out of the exercise by them of any rights hereunder. If any notice of a proposed
sale or other disposition of Collateral shall be required by law, such notice
shall be deemed reasonable and proper if given at least ten days before such
sale or other disposition.

     SECTION 5.4 REGISTRATION RIGHTS.

          (a) If the Joint Collateral Agent shall determine to exercise its
right to sell any or all of the Pledged Securities pursuant to Section 5.3
hereof, and if in the opinion of the Joint Collateral Agent it is necessary or
advisable to have the Pledged Securities, or that portion thereof to be sold,
registered under the provisions of the Securities Act, the relevant Grantor will
cause any Issuer thereof to: (i) execute and deliver, and cause the directors,
members, managers and officers of such Issuer to execute and deliver, all such
instruments and documents, and do or cause to be done all such other acts as may
be, in the opinion of the Joint Collateral Agent, necessary or advisable to
register the Pledged Securities, or that portion thereof to be sold, under


                                       17

<PAGE>

the provisions of the Securities Act, (ii) cause the registration statement
relating thereto to become effective and to remain effective for a period of one
year from the date of the first public offering of the Pledged Securities, or
that portion thereof to be sold, and (iii) make all amendments thereto and/or to
the related prospectus which, in the opinion of the Joint Collateral Agent, are
necessary or advisable, all in conformity with the requirements of the
Securities Act and the rules and regulations of the Securities and Exchange
Commission applicable thereto. Each Grantor agrees to cause any Issuer to comply
with the provisions of the securities or "Blue Sky" laws of any and all
jurisdictions which the Joint Collateral Agent shall designate and to make
available to its security holders, as soon as practicable, an earnings statement
(which need not be audited) which will satisfy the provisions of Section 11(a)
of the Securities Act.

          (b) Each Grantor recognizes that the Joint Collateral Agent may be
unable to effect a public sale of any or all the Pledged Securities, by reason
of certain prohibitions contained in the Securities Act and applicable state
securities laws or otherwise, and may be compelled to resort to one or more
private sales thereof to a restricted group of purchasers which will be obliged
to agree, among other things, to acquire such securities for their own account
for investment and not with a view to the distribution or resale thereof. Each
Grantor acknowledges and agrees that any such private sale may result in prices
and other terms less favorable than if such sale were a public sale and,
notwithstanding such circumstances, agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner. The Joint
Collateral Agent shall be under no obligation to delay a sale of any of the
Pledged Securities for the period of time necessary to permit the Issuer thereof
to register such securities for public sale under the Securities Act, or under
applicable state securities laws, even if such Issuer would agree to do so.

          (c) Each Grantor agrees to use its best efforts to do or cause to be
done all such other acts as may be necessary to make such sale or sales of all
or any portion of the Pledged Securities pursuant to this Section 5.4 valid and
binding and in compliance with any and all other applicable Governmental
Requirements. Each Grantor further agrees that a breach of any of the covenants
contained in this Section 5.4 will cause irreparable injury to the Joint
Collateral Agent and the other Secured Parties, that the Joint Collateral Agent
and the other Secured Parties have no adequate remedy at law in respect of such
breach and as a consequence, that each and every covenant contained in this
Section 5.4 shall be specifically enforceable against such Grantor, and such
Grantor hereby waives and agrees not to assert any defenses against an action
for specific performance of such covenants except for a defense that no Event of
Default has occurred under the Indenture.

     SECTION 5.5 WAIVER; DEFICIENCY. Each Grantor shall remain liable for any
deficiency if the proceeds of any sale or disposition of the Collateral are
insufficient to pay the Secured Obligations and the reasonable fees and
disbursements of any attorneys employed by the Joint Collateral Agent or any
other Secured Party to collect such deficiency.

<PAGE>

          (a) Each Grantor hereby irrevocably constitutes and appoints the Joint
Collateral Agent and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of such Grantor and in the name of
such Grantor or in its own name, for the purpose of carrying out the terms of
this Agreement, to take any and all appropriate action and to execute any and
all documents and instruments which may be necessary or desirable to accomplish
the purposes of this Agreement, and, without limiting the generality of the
foregoing, such Grantor hereby gives the Joint Collateral Agent the power and
right, on behalf of such Grantor, without notice to or assent by such Grantor,
to do any or all of the following:

     to any other Collateral and file any claim or take any other action or
     proceeding in any court of law or equity or otherwise deemed appropriate by
     the Joint Collateral Agent for the purpose of collecting any and all such
     moneys due with respect to any other Collateral whenever payable;

               (2) in the case of any Copyright, Patent or Trademark, execute,
     deliver and have recorded, any and all agreements, instruments, documents
     and papers as the Joint Collateral Agent may request to evidence the Joint
     Collateral Agent's security interest in such Copyright, Patent or Trademark
     and the goodwill and General Intangibles of such Grantor relating thereto
     or represented thereby;

               (3) pay or discharge Taxes and Liens levied or placed on or
     threatened against the Collateral, effect any repairs or any insurance

               (5) (A) direct any party liable for any payment under any of the
     Collateral to make payment of any and all moneys due or to become due
     thereunder directly to the Joint Collateral Agent or as the Joint
     Collateral Agent shall direct; (B) ask or demand for, collect, and receive
     payment of and receipt for, any and all moneys, claims and other amounts
     due or to become due at any time in respect of or arising out of any
     Collateral; (C) sign and indorse any invoices, freight or express bills,
     bills of lading, storage or warehouse receipts, drafts against debtors,

     limitation, any negotiable Documents) in connection with any of the
     Collateral; (D) commence and prosecute any suits, actions or proceedings at
     law or in equity in any court of competent jurisdiction to collect the
     Collateral or any portion thereof and to enforce any other right in respect
     of any Collateral; (E) defend any suit, action or proceeding brought
     against such Grantor with respect to any Collateral; (F) settle, compromise
     or adjust any such suit, action or proceeding and, in connection therewith,
     give such discharges or releases as the Joint Collateral Agent may deem
     appropriate; (G) assign any Copyright, Patent or Trademark (along with the
     goodwill of the business to which any such Copyright, Patent or Trademark
     pertains), throughout the


                                       19

<PAGE>

     world for such term or terms, on such conditions, and in such manner, as
     the Joint Collateral Agent shall in its sole discretion determine; and (H)
     generally, sell, transfer, pledge and make any agreement with respect to or
     otherwise deal with any of the Collateral as fully and completely as though
     the Joint Collateral Agent were the absolute owner thereof for all
     purposes, and do, at the Joint Collateral Agent's option and such Grantor's
     expense, at any time, or from time to time, all acts and things which the
     Joint Collateral Agent deems necessary to protect, preserve or realize upon
     the Collateral and the Joint Collateral Agent's security interests therein
     and to effect the intent of this Agreement, all as fully and effectively as
     such Grantor might do.

Anything in this Section 6.1(a) to the contrary notwithstanding, the Joint
Collateral Agent agrees that it will not exercise any rights under the power of
attorney provided for in this Section 6.1(a) unless an Event of Default shall
have occurred and be continuing.

          (b) The Joint Collateral Agent may (but without any obligation to do
so) (i) perform or satisfy any of the Grantor's and any other Obligated Party's
obligations under or pursuant to this Agreement, the other Indenture Documents
and any documents evidencing the Parity Lien Obligations, if any, which in each
case remain unsatisfied (after providing any notice and opportunity to cure to
which such Grantor or other Obligated Party is entitled under any other
provision of any Indenture Document or document evidencing Parity Lien
Obligations, if any), and (ii) take all other actions and pay such amounts and
claims as Joint Collateral Agent determines in its sole but reasonable
discretion, is necessary or appropriate to protect the rights and interests of
the Joint Collateral Agent and the other Secured Parties under this Agreement,
the other Indenture Documents and any documents evidencing Parity Lien
Obligations and otherwise with respect to the Notes or to preserve and protect
the Collateral or any part thereof from loss.

          (c) The expenses of the Joint Collateral Agent incurred in connection
with actions undertaken as provided in this Section 6.1, together with interest
thereon at a rate per annum equal to the rate per annum at which interest would
then be payable under the Indenture on past due amounts, from the date of
payment by the Joint Collateral Agent to the date reimbursed by any Grantor,
shall be payable by such Grantor to the Joint Collateral Agent on demand.

          (d) Each Grantor hereby ratifies all that said attorneys shall
lawfully do or cause to be done pursuant to the powers granted in this Section
6.1. All powers, authorizations and agencies contained in this Agreement are
coupled with an interest and are irrevocable until this Agreement is terminated
and the security interests created hereby are released.

     SECTION 6.2 DUTY OF THE JOINT COLLATERAL AGENT. The Joint Collateral
Agent's sole duty with respect to the custody, safekeeping and physical
preservation of the Collateral in its possession, under the UCC or otherwise,
shall be to deal with it in the same manner as the Joint Collateral Agent deals
with similar property for its own account. None of the Joint Collateral Agent,
any other Secured Party, nor any of their respective officers, directors,
employees or agents shall be liable for failure to demand, collect or realize
upon any of the Collateral or for any delay in doing so or shall be under any
obligation to sell or otherwise dispose of any Collateral upon the request of
any Grantor or any other Person or to take any other action whatsoever with
regard to the Collateral or any part thereof. The powers conferred on the Joint


                                       20

<PAGE>

Collateral Agent hereunder are solely to protect the Joint Collateral Agent's
interests in the Collateral and shall not impose any duty upon the Joint
Collateral Agent or any other Secured Party to exercise any such powers. The
Joint Collateral Agent shall be accountable only for amounts that it actually
receives as a result of the exercise of such powers, and neither it nor any of
its officers, directors, employees or agents shall be responsible to any Grantor
or any other Credit Party for any act or failure to act hereunder, except for
their own gross negligence or willful misconduct.

     SECTION 6.3 FINANCING STATEMENTS. Pursuant to the UCC and any other
applicable laws, each Grantor authorizes the Joint Collateral Agent to file or
record financing statements and other filing or recording documents or
instruments with respect to the Collateral in such form and in such offices as
the Joint Collateral Agent reasonably determines appropriate to perfect the
security interests of the Joint Collateral Agent under this Agreement. A
photographic or other reproduction of this Agreement shall be sufficient as a
financing statement or other filing or recording document or instrument for
filing or recording in any jurisdiction.

     SECTION 6.4 AUTHORITY OF THE JOINT COLLATERAL AGENT. Each Grantor
acknowledges that the rights and responsibilities of the Joint Collateral Agent
under this Agreement with respect to any action taken by the Joint Collateral
Agent or the exercise or non-exercise by the Joint Collateral Agent of any
option, voting right, request, judgment or other right or remedy provided for
herein or resulting or arising out of this Agreement shall, as between the Joint
Collateral Agent and the other Secured Parties, be governed by the Indenture,
and by such other agreements with respect thereto as may exist from time to time
among them, but, as between the Joint Collateral Agent and such Grantor, the
Joint Collateral Agent shall be conclusively presumed to be acting as Joint
Collateral Agent for the Secured Parties with full and valid authority so to act
or refrain from acting, and such Grantor shall not be under any obligation, or
entitlement, to make any inquiry respecting such authority.

     SECTION 7.2 NOTICES. All notices, requests and demands to or upon the Joint
Collateral Agent, any other Secured Party, or any Grantor hereunder shall be
effected in the manner provided for in Section 14.2 of the Indenture.

     SECTION 7.3 NO WAIVER; REMEDIES CUMULATIVE. No failure or delay on the part
of any Grantor or the Joint Collateral Agent in exercising any right or remedy
under this Agreement or any other Indenture Document and no course of dealing
between such Grantor and the Joint Collateral Agent or any Secured Party shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right or remedy under this Agreement or any other Indenture Document preclude
any other or further exercise thereof or the exercise of any other right or
remedy under this Agreement or any other Indenture Document. The rights and
remedies herein expressly


                                       21

<PAGE>

provided are cumulative and not exclusive of any rights or remedies which any
Grantor, the Joint Collateral Agent or any Secured Party would otherwise have.
No notice to or demand on any Grantor not required under this Agreement or any
other Indenture Document in any case shall entitle such Grantor or any other
Grantor to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Joint Collateral Agent
or the Secured Parties to any other or further action in any circumstances
without notice or demand.

     SECTION 7.4 ENFORCEMENT EXPENSES; INDEMNIFICATION.

          (a) Each Grantor agrees to pay or reimburse the Joint Collateral Agent
for all of its costs and expenses incurred in enforcing or preserving any rights
under this Agreement and the other Indenture Documents to which such Grantor is
a party, including, without limitation, the reasonable fees and disbursements of
counsel to the Joint Collateral Agent.

          (b) Each Grantor agrees to pay, and to save the Joint Collateral Agent
and the Secured Parties harmless from, any and all liabilities with respect to,
or resulting from any delay in paying, any and all stamp, excise, sales or other
taxes which may be payable or determined to be payable with respect to any of
the Collateral or in connection with any of the transactions contemplated by
this Agreement.

          (c) Each Grantor agrees to pay, and to save the Joint Collateral Agent
and the Secured Parties harmless from, any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever with respect to the execution,
delivery, enforcement, performance and administration of this Agreement, to the
same extent each Grantor would be required to do so pursuant to Sections 7.7 and
10.1(a) of the Indenture, as if each Parity Lien Holder were a "Holder" under
the Indenture.

          (d) The agreements in this Section 7.4 shall survive repayment of the
Notes and all other amounts payable under the Indenture, the other Indenture
Documents and any documents evidencing Parity Lien Obligations.

     SECTION 7.5 SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby, except that no Grantor may
assign or otherwise transfer any of its rights or obligations hereunder except
in accordance with the terms of the Indenture (and any attempted assignment or
transfer by such Grantor without such consent shall be null and void).

     SECTION 7.6 SET-OFF. In addition to and not in limitation of all rights of
offset that the Joint Collateral Agent, the Trustee, any Holder or any Parity
Lien Holder may have under applicable law, the Trustee, each Holder and each
Parity Lien Holder shall, upon the occurrence of any Event of Default and at any
time during the continuance thereof and whether or not such Holder, such Parity
Lien Holder or the Trustee has made any demand or the Notes are matured, have
the right at any time and from time to time, without notice to any Grantor (any
such notice being expressly waived by each Grantor) to set-off and apply any and
all deposits (general or special, time or demand, provisional or final) at any
time held and other indebtedness at any time owing by any Holder, any Parity
Lien Holder or the Trustee to or for the credit or the account of


                                       22

<PAGE>

any Grantor against any and all of the Notes owing to such Holder, such Parity
Lien Holder or the Trustee.

     SECTION 7.7 COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original but all of which
shall together constitute one and the same instrument.

     SECTION 7.8 SEVERABILITY. In the event that any one or more of the
provisions contained in this Agreement shall, for any reason, be held invalid,
illegal or unenforceable in any respect, (a) each Grantor agrees that such
invalidity, illegality or unenforceability shall not affect any other provision
of this Agreement and (b) each Grantor and the Joint Collateral Agent (acting on
behalf and at the direction of the Trustee, the Parity Lien Holders and the
Holders) will negotiate in good faith to amend such provision so as to be legal,
valid, and enforceable.

     SECTION 7.9 ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER INDENTURE
DOCUMENTS EMBODY THE ENTIRE AGREEMENT AND UNDERSTANDING BETWEEN THE JOINT
COLLATERAL AGENT, THE TRUSTEE, THE PARITY LIEN HOLDERS, THE OTHER HOLDERS, THE

required to become a party to this Agreement pursuant to Section 4.14 of the
Indenture shall become a Grantor for all purposes of this Agreement upon
execution and delivery by such Subsidiary of an Assumption Agreement in the form
of Annex I hereto.

     SECTION 7.14 RELEASES

          (a) At such time as the obligations of the Company and the Guarantors
shall have been defeased or discharged in accordance with the provisions of
Article VIII of the Indenture and the Parity Lien Obligations shall have been
paid in full, the Collateral shall be released from the Liens created hereby,
and this Agreement and all obligations (other than those expressly stated to
survive such termination) of the Joint Collateral Agent and each Grantor
hereunder shall terminate, all without delivery of any instrument or performance
of any act by any party, and all rights to the Collateral shall revert to the
applicable Grantor. At the request and joint and several expense of the Grantors
following any such termination, the Joint Collateral Agent shall promptly
deliver to the appropriate Grantor any Collateral held by the Joint Collateral
Agent hereunder, and promptly execute and deliver to such Grantor such documents
as such Grantor shall reasonably request to evidence such termination.

          (b) If any of the Collateral shall be sold, transferred or otherwise
disposed of by any Grantor in a transaction permitted by the Indenture or, if
any Pledged Securities become subject to clause (v) of the proviso at the end of
Section 2.1, then the Joint Collateral Agent, at the request and sole expense of
such Grantor, shall promptly execute and deliver to such Grantor all releases or
other documents reasonably necessary or desirable for the release of the Liens
created hereby on such Collateral.

     SECTION 7.15 REINSTATEMENT. The provisions of this Agreement shall remain
in full force and effect and continue to be effective should any petition be
filed by or against any Grantor for liquidation or reorganization, should such
Grantor become insolvent or make an assignment for the benefit of creditors or
should a receiver or trustee be appointed for all or any part of such Grantor's
assets or should any other financial impairment occur, and shall continue to be
effective or be reinstated, as the case may be, if at any time payment or
performance of the Notes, or any part thereof, is, pursuant to applicable law,
rescinded or reduced in amount, or must otherwise be restored or returned to any
obligee of the Notes, whether as a "voidable preference", "fraudulent
conveyance", or otherwise, all as though such payment or performance had not
been made. In the event that any payment, or any part thereof, is rescinded,
reduced, restored, or returned, the Notes shall be reinstated and deemed reduced
only by such amount paid and not so rescinded, reduced, restored or returned.

                             COMMERCIAL TORT CLAIMS

On October 26, 2005, VeraSun Fort Dodge, LLC (VFD) sent a letter to Fagen, Inc,
John Zink Company LLC and Industrial Air Technology notifying them of a property
loss that VFD sustained on September 10, 2005 when the induced draft fan on
thermal oxidizer #2 suffered catastrophic damage. As a result of this event, VFD
incurred damage to its structures and equipment, as well as loss of income and
other damages. VFD has not yet completed its investigation of the causes of the
event or determined the exact amount of damages it incurred. No suit has been
filed against these parties or VFD's insurers.
