Ave., P.O. Box 888, Ames, Iowa 50010 (the “Borrower”) and AGSTAR FINANCIAL
SERVICES, PCA, a United States instrumentality, (the “Lender”). The parties
hereto enter into this Agreement with reference to the following facts:

A. The Lender has agreed to make certain loans to the Borrower, in the original
principal amount of Twenty Five Million Nine Hundred Sixty Thousand Seven
Hundred Thirty One Dollars and 50/cents ($25,960,731.50) (the “Loan”). The Loan
is evidenced by that certain Master Loan Agreement, First Supplement to the
Master Loan Agreement (Term Loan), Term Note, Second Supplement to the Master
Loan Agreement (Revolving Line of Credit Loan), and Revolving Line of Credit
Note, all of even date herewith, (as, amended, modified, extended, or restated,
from time to time, collectively, the “Loan Agreement”), and which Loan Agreement
is to be secured by, among other things, a Mortgage (Open End) of even date
herewith, as amended, modified, extended, or restated from time to time (the
“Mortgage”) creating a lien on certain real property located in Jasper County,
Iowa, more particularly described on Exhibit A attached hereto, together with
the improvements and personal property located thereon (collectively, the
“Premises”).

B. The making of the Loan is subject to the condition precedent, among others,
that Borrower makes and delivers this Agreement to the Lender. Borrower
acknowledges that the Borrower is entering into this Agreement for the purpose
of inducing the Lender to make the Loan to it, and further acknowledges that the
Lender would not make the Loan in the absence of this Agreement, notwithstanding
any contrary provision in the Loan Agreement, the Notes, the Mortgage or any
other document given in connection with the Loan (such other documents together
with the Mortgage and the Loan Agreement being collectively referred to herein
as the “Collateral Loan Documents”).

C. Borrower acknowledges that the Lender may sustain Losses (as defined in
Section 4(a)) both prior to and following a foreclosure of the Lender’s security
interest in the Premises pursuant to the Mortgage or the Collateral Loan
Documents or conveyance in lieu thereof, as well as after the Notes are paid in
accordance with its terms.

items are included under or regulated by any federal, state or local law, rule
or regulation pertaining to environmental matters, as now or hereafter enacted

--------------------------------------------------------------------------------

any agreement or other instrument to which the Borrower may be a party or by
which the Borrower or any of its assets are bound.

3. Covenants.

(a) Compliance with Laws. Borrower shall comply strictly and in all material
respects with the requirements of the Environmental Laws.

(b) Remedial Work. If any investigation, site monitoring, abatement,
containment, clean-up, removal or other remedial work of any kind or nature (the
“Remedial Work”) is necessary or advisable because of, or in connection with,
the current or future presence, suspected presence, release or suspected release
of a Hazardous Substance in, on, from or with respect to the Premises (or any
portion thereof), Borrower shall promptly (and in all events within the time
required under any applicable Environmental Law, order or agreement) commence
and thereafter diligently prosecute to completion, all such Remedial Work;
provided however, the Lender may require that Borrower commence such Remedial
Work no later than thirty (30) days after written demand for performance from
the Lender. Such Remedial Work shall be completed in accordance with all
applicable Environmental Laws (and in all events in a manner reasonably
satisfactory to the Lender). The Lender shall have the right to approve any
contractors performing Remedial Work in advance (which approval will not be
unreasonably withheld) and to require that the Remedial Work be performed under
the supervision of a consulting engineer approved by the Lender (which approval
will not be unreasonably withheld). All costs and expenses in connection with
such Remedial Work shall be paid by Borrower, including without limitation, the
Lender’ fees and costs incurred with monitoring and reviewing the Remedial Work.

(c) No Unauthorized Substances. Borrower hereby covenants and agrees not to take
or fail to take any action that will result in the unauthorized presence, use,
storage, disposal, processing, generation, transportation, treatment, discharge
or release of any Hazardous Substances in, on, from or with respect to the
Premises.

(d) Obligation to Notify Lender. Borrower shall immediately notify the Lender
should Borrower become aware of (i) any Hazardous Substance problem or liability
with respect to the Premises; (ii) any unauthorized release or discovery of any
Hazardous Substance or other contamination, liability or problem respecting the
Premises; or (iii) any litigation or threat of litigation relating to any
alleged unauthorized release of any Hazardous Substance or discovery of any
Hazardous Substance or other contamination, liability or problem respecting the
Premises. Borrower shall promptly forward to the Lender copies of all orders,
notices, permits and applications or other communications and reports in
connection with any unauthorized release or discovery of any Hazardous Substance
or other contamination, or any other environmental matters affecting the
Premises.

(e) Environmental Audit. Promptly upon the written and good faith request of the
Lender from time to time, and for the reasons recited therein, Borrower shall
provide the Lender, at Borrower’s expense, with an environmental site assessment
or environmental audit report in form and content acceptable to the Lender
regarding the Premises (an “Environmental Audit”). The Environmental Audit shall
be prepared by an environmental engineering firm reasonably acceptable to
Lender, shall assess with a reasonable degree of certainty the presence or
absence of any Hazardous Substances and shall indicate the potential costs in
connection with any site monitoring, abatement, containment, clean-up, removal
or other remedial work of any

--------------------------------------------------------------------------------

kind or nature relating to Hazardous Substances found in, on, under, at, within
or emanating from the Premises.

4. Indemnity.

(a) Scope of Indemnity. Borrower hereby agrees to indemnify, save, defend (at
Borrower’s sole cost and expense) and hold harmless Lender and the officers,
directors, shareholders, agents, attorneys and employees of Lender, and the
successors and assigns of each of the foregoing (all of such persons or entities
being collectively referred to herein as “Indemnified Parties” and each such
reference shall refer jointly and severally to each such persons) from and
against the full amount of any and all Losses (as hereinafter defined),
regardless of the acts or omissions of Indemnified Parties except as hereinafter
specifically excepted. “Losses” shall mean any and all liabilities, obligations,
losses, damages, penalties, claims, actions, suits and costs and expenses
(including but not limited to all costs and expenses associated with court or
administrative proceedings (through the appellate level)) such as condemnation,
bankruptcy and other administrative proceedings, as well as any other of the
foregoing where a proof of claim is by law required to be filed, or in which it
becomes necessary to defend or uphold the terms of this Agreement, together with
reasonable attorneys’ fees and other professional and consultant’s expenses
incurred in investigating, preparing for, serving as a witness in or defending
against any action or proceeding whether actually commenced or threatened),
arising from, in respect of, as a consequence of, or in connection with, the
ownership, operation or use of the Premises by the Borrower, its employees,
representatives and agents, and all other persons acting on behalf of, or at the
direction of, the Borrower, including, but not limited to, any of the following:
(i) the presence, use, storage, disposal, processing, generation,
transportation, treatment, discharge or release of any Hazardous Substances in,
on, from or with respect to the Premises, regardless of whether the same is
caused or permitted by Borrower or any other person or entity; (ii) the removal
of any Hazardous Substances on, from or with respect to the Premises, regardless
of whether the same is performed by Borrower or any other person or entity and
regardless of whether or not such removal is rendered voluntarily or pursuant to
a court order or the order of an administrative agency; (iii) claims asserted by
any person or entity (including, without limitation, any governmental or
quasi-governmental agency, authority, board, bureau, commission, department,
instrumentality, public body, court or administrative tribunal (a “Governmental
Agency”)), in connection with or in any way arising out of the presence, use,
storage, disposal, processing, generation, transportation, treatment, discharge
or release of any Hazardous Substances in, on, from or with respect to the
Premises, either prior to or after the date of this Agreement and either prior
to or after the time that Borrower became the owner of the Premises; (iv) the
violation or claimed violation of any Environmental Laws in regard to the
Premises, whether such violation or claimed violation occurred prior to or after
the date of this Agreement and regardless of whether such violation occurred
prior to or after the time that Borrower became the owner of the Premises;
(v) the preparation of an Environmental Audit on the Premises, whether conducted
or authorized by Borrower or any other person or entity and the implementation
of any Environmental Audit’s recommendations; (vi) the cost of enforcing this
Agreement; and (vii) any other environmental matter respecting the Premises.
Lender may employ the attorneys and/or consultants of its choice. The foregoing
shall not apply to Losses resulting from Hazardous Substances brought on to the
Premises by any Indemnified Party.

--------------------------------------------------------------------------------

(b) Effect. Borrower’s obligations under this Agreement shall arise upon the
discovery of the presence, use, storage, disposal, processing, generation,
transportation, treatment, discharge or release of any Hazardous Substances in,
on, from or with respect to the Premises, whether or not a Governmental Agency
has taken or threatened any action in connection therewith.

(c) Lender’s Self-Help Rights. If Borrower fails to comply with the requirements
of any Environmental Law, to perform any Remedial Work as required herein, or to
perform any other obligation of Borrower hereunder, Lender may at its election,
but without any obligation to do so, take any and all actions as Lender shall
deem necessary or advisable in order to cure Borrower’s failure, in which event
Borrower shall reimburse Lender for all costs and expenses thereof or incurred
in connection therewith, as provided in Section 5.

(d) Claim Settlement. So long as Lender is the holder of the Loan Agreement, the
Notes or a mortgagee or assignee under the Mortgage or any of the Collateral
Loan Documents or if Lender at any time shall have become a mortgagee in
possession or a successor in interest to Borrower by foreclosure or deed in lieu
of foreclosure with respect to all or part of the Premises, Borrower shall not
settle any claim relating to the Premises under or on account of any
Environmental Law without Lender’s prior written consent, which consent may be
withheld in Lender’s sole and absolute discretion.

5. Payments. Payments due Lender and other Indemnified Parties under this
Agreement shall be due and payable as the same are incurred, without the
requirement that such party wait for the ultimate outcome of any litigation,
claim or other proceeding. Within a reasonable time after any sums are expended
or any Losses are incurred, the Lender or other Indemnified Party (as
applicable) shall notify Borrower thereof; provided, however, that failure to
give such notice shall not relieve Borrower from any liability, duty or
obligation hereunder. Borrower will pay sums due within thirty (30) days after
receipt of notice itemizing the amounts incurred to the effective date of such
notice. Borrower shall pay interest on any amount not paid when due at an
interest rate equal to the Default Rate (as defined in the Loan Agreement and
the Notes), but in no event to exceed the maximum interest rate allowed by law.

6. Obligation to Defend.

(a) Assumption of Defense. Upon request of any Indemnified Party, Borrower shall
be bound to defend any and all actions or proceedings that may be brought
against such Indemnified Party in connection with or arising out of the matters
covered by this Agreement. In the event that Borrower is defending an
Indemnified Party, Borrower may settle a claim against the Indemnified Party
only with the Indemnified Party’s prior written consent, which consent may be
withheld in the Indemnified Party’s sole and absolute discretion.

(b) Conduct of Defense; Participation by Indemnified Party. In the event an
Indemnified Party has required Borrower to defend it, such defense shall be
conducted by reputable attorneys retained by Borrower, satisfactory to the
Indemnified Party in its sole and absolute discretion, at Borrower’s sole cost
and expense. In addition, the Indemnified Party shall have the right to
participate in such proceedings and to be represented by attorneys of its own
choosing. In such case, the Indemnified Party shall be responsible for the cost
of such participation unless the Indemnified Party shall have concluded, based
on the advice of counsel, that the interests of the Indemnified Party and of
Borrower in the action conflict in such a manner and to such an extent as to
require, consistent with applicable standards of professional

 

6

--------------------------------------------------------------------------------

responsibility, the retention of separate counsel for the Indemnified Party, in
which event Borrower shall pay for separate counsel chosen by the Indemnified
Party.

(c) Defense by Indemnified Party. Notwithstanding the foregoing, an Indemnified
Party may elect in its sole and absolute discretion at any time to conduct its
own defense of any action or proceeding that may be brought against it or to
which it may be a party. In such event, Borrower shall be conclusively liable
for the results obtained by the Indemnified Party, including without limitation
the amount of any judgment or good faith, out-of-court settlement or compromise.
In addition, Borrower shall be liable for any and all costs and expenses,
including, but not limited to, all reasonable attorney’s fees, that the
Indemnified Party incurs.

7. Default. Time is of the essence hereof. The term “Default,” as used in this
Agreement, shall mean the occurrence of any one or more of the following events:

(a) The failure of Borrower punctually and properly to perform any covenant,
condition or agreement contained in this Agreement;

(b) The filing of a proceeding in bankruptcy or arrangement or reorganization by
or against Borrower pursuant to the United States Bankruptcy Code or any similar
law, federal or state, including but not limited to:

(i) Borrower shall file a voluntary petition in bankruptcy or shall be
adjudicated bankrupt or insolvent, or shall file any petition or answer seeking
or acquiescing in any reorganization, arrangement, composition, readjustment,
liquidation, dissolution or similar relief for itself under any present or
future federal, state, or other statute, law or regulation relating to
bankruptcy, insolvency or other relief for debtors, or shall seek or consent to
or acquiesce in the appointment of any trustee, receiver or liquidator of
Borrower, or shall make any general assignment for the benefit of creditors, or
shall admit in writing its inability to pay or shall fail to pay its debts
generally as they become due;

(ii) A court of competent jurisdiction shall enter an order, judgment or decree
approving a petition filed against Borrower seeking any reorganization,
dissolution or similar relief under any present or future federal, state, or
other statute, law or regulation relating to bankruptcy, insolvency or other
relief for debtors, or Borrower shall be the subject of an order for relief
entered by such a court, and such order, judgment or decree shall remain
unvacated and unstayed for an aggregate of sixty (60) days (whether or not
consecutive) from the first date of entry thereof, or any trustee, receiver,
custodian or liquidator of Borrower shall be appointed without the consent or
acquiescence of Borrower and such appointment shall remain unvacated and
unstayed for an aggregate of sixty (60) days (whether or not consecutive);

(c) The determination by Lender that any representation or warranty of Borrower
set forth in this Agreement or delivered in connection herewith or as required
from time to time hereby is false, misleading or erroneous in any material
respect as of the date thereof; or

(d) The occurrence of a Default under the Loan Agreement, Notes, the Mortgage,
or any of the Collateral Loan Documents.

8. Remedies. If any Default shall have occurred, then Lender shall have the
right to enforce any legal or equitable remedy against the Borrower and to sue
for any sums whether damages, interest or any other sums required to be paid
under the terms of this Agreement and

 

7

--------------------------------------------------------------------------------

without prejudice to the right of Lender thereafter to enforce any appropriate
remedy against Borrower. The rights of the Lender arising under the clauses and
covenants contained in this Agreement shall be separate, distinct and cumulative
and none of them shall be construed as an election to proceed under any one
provision herein to the exclusion of any other provision, anything herein or
otherwise to the contrary notwithstanding.

9. Invalidity. If any term or provision of this Agreement shall be invalid,
illegal or unenforceable, such term or provision shall be severable from the
rest of this Agreement and the validity, legality or enforceability of the
remaining terms and provisions shall not in any way be affected or impaired
thereby.

10. Separate Obligations. The purpose of this Agreement is to protect Lender
against liability, loss, damage, cost or expense with respect to Hazardous
Substances and Environmental Laws relating to the Premises as provided in this
Agreement, and not as security for payment of the indebtedness evidenced by the
Loan Agreement, Notes or performance of the obligations under the Mortgage and
the Collateral Loan Documents. The obligations of Borrower under this Agreement
are separate from, independent of and in addition to the indebtedness and
obligations under the Loan Agreement, Notes, the Mortgage, and the Collateral
Loan Documents. The liability of Borrower under this Agreement shall not be
limited to or measured by the amount of the indebtedness owed under the Loan
Agreement, the Notes or the Mortgage or the value of the Premises. This
Agreement is not secured by the Mortgage, the obligations hereunder are separate
and independent, and shall not be extinguished by the release or foreclosure of
the Mortgage. Borrower shall be fully and personally liable for all obligations
of Borrower under this Agreement and a separate action may be brought and
prosecuted against any or all of the Borrowers on this Agreement. The liability
of Borrower under this Agreement shall not be subject to any limitation set
forth in the Loan Agreement, the Notes, the Mortgage, or any of the Collateral
Loan Documents, on personal liability for the payment of the indebtedness
evidenced by the Loan Agreement, the Notes, or the remedies of Lender for
enforcement of the obligations under the Loan Agreement, the Notes, the
Mortgage, or the Collateral Loan Documents or the recourse of Lender for
satisfaction of such obligations. This Agreement and the obligations of Borrower
hereunder shall survive, and remain in full force and effect after any
reconveyance of the Mortgage or any foreclosure of the Mortgage (whether by
judicial action, exercise of the power of sale, deed in lieu of foreclosure, or
otherwise) with respect to any release or threatened release of any Hazardous
Substances in, on or under the Premises or any past, present or future violation
of any Environmental Laws at the Premises which occurred, or the onset of which
occurred, before such reconveyance or foreclosure, and Lender shall have the
right to enforce this Agreement after any such reconveyance or foreclosure. To
the extent permitted by applicable law, Borrower waives the right to assert any
statute of limitations as a bar to the enforcement of this Agreement or to any
action brought to enforce this Agreement. This Agreement shall not affect,
impair or waive any rights or remedies of Lender or any obligations of Borrower
with respect to Hazardous Substances created or imposed by Environmental Laws
(including Lender’s rights of reimbursement or contribution under Environmental
Laws). The remedies in this Agreement are cumulative and in addition to all
remedies provided by law.

11. Notice. Any notice that Borrower or Lender may be required or entitled to
give to the other party hereunder shall be in writing and shall be deemed given
when the same is (a) delivered by personal service, (b) delivered by nationwide
overnight delivery service (with
