Nebraska, has power to enter into this Agreement, the Remarketing Agreement and
the Reimbursement Agreement and to use the Project for the purpose set forth in

this Agreement, the Remarketing Agreement and the Reimbursement Agreement, and
has approved the Indenture;

      (2) The execution and delivery of this Agreement, the Remarketing
Agreement and the Reimbursement Agreement, the consummation of the transactions
contemplated thereby, and the fulfillment of the terms and conditions thereof do
not and will not conflict with or result in a breach of any of the terms or
conditions of the Company's articles of incorporation, any restriction or any
agreement or instrument to which the Company is now a party or by which it is
bound or to which any property of the Company is subject, and do not and will
not constitute a default under any of the foregoing, or be in violation of any
order, decree, statute, rule or regulation of any court or any state or federal
regulatory body having jurisdiction over the Company or its properties,
including the Project, and do not and will not result in the creation or
imposition of any lien, charge or encumbrance of any nature upon any of the
property or assets of the Company contrary to the terms of any instrument or
agreement to which the Company is a party or by which it is bound;

      (3) The design and plan of the Project comprises a project as contemplated

      (4) To the best of the Company's knowledge, as of the date hereof, the use

allowance for depreciation for a Manufacturing Facility within the meaning of
Sections 144(a)(1) and (12) of the Code;

      (7) A major inducement to the Company to acquire and construct the Project
was the source of financing provided under the Act and the assurance the Company
received from the Issuer that such financing would be made available to the
Company; and any Project Costs heretofore incurred by the Company for which the
Company will hereafter seek reimbursement as provided in Section 3.5, were
incurred in anticipation of reimbursement from the proceeds of revenue bonds of
the Issuer; and the Company investigated the possibility of such financing prior
to incurring such Project Costs; and the Company did not commence acquisition of
any portion of the Project for which it shall seek reimbursement from the
proceeds of the Bonds hereunder prior to June 28, 1996;

no intention now or in the foreseeable future to voluntarily sell, surrender or
otherwise transfer, in whole or part, its interest in the Project;

      (9) The Cost of the Project is estimated to be at least equal to the face

warranty or representation, either express or implied, that the amount in the
Construction Fund will be sufficient to pay such Costs or that the Project will
be suitable to the Company's needs;

      (10) Neither the Company nor any other Principal User of the Project nor
any Related Person to the Company or such other

of the Issuer, other than the Project, financed in whole or in part by an issue
of outstanding Private Activity Bonds of a political subdivision, except as
described in Exhibit B;

      (11) There are no actions, suits, or proceedings pending or, to the
knowledge of the Company, threatened against the Company or any property of the
Company in any court or before any federal, state, municipal or other

material adverse effect upon the Company or upon the business or properties of
the Company; and the Company is not in default with respect to any order of any
court or governmental agency;

                        Bondholders.

            The Company recognizes the authority of the Issuer to assign its
interest in and pledge monies receivable under this Agreement (other than
certain payments required to be made to the Issuer corresponding to its Reserved
Rights) to the Trustee as security for the payment of the principal of and
interest and redemption premiums, if any, on the Bonds, and the payment of all
fees and expenses of the Trustee; and hereby agrees to be bound by, and joins
with the Issuer in the grant of a security interest to the Trustee in any rights
and interest the Company may have in sums held in the Funds described in Article
VI pursuant to the terms and conditions of the Indenture to secure payment of
the Bonds. Each of the terms and provisions of this Agreement is a covenant for
the use and benefit of the Trustee and the Holders of the Bonds, so long as any
thereof shall remain Outstanding; but upon payment in full of the Bonds in
accordance with Article IX of the Indenture and of all fees and charges of the
Trustee and Paying Agent, all references in this Agreement to the Bonds, the
Holders thereof and the Trustee shall be ineffective, and neither the Trustee
nor the Holders of any of the Bonds shall thereafter have any rights hereunder,
save and except those that shall have theretofore vested or that arise from
provisions hereunder which survive termination of this Agreement.

            Section 7.2 Inspection and Access.

            The Company agrees that the Trustee and Issuer and their duly
authorized agents shall have the right at all reasonable times to examine and
inspect the Project and all books and records of the Company and for that
purpose to enter upon the Project Premises, and shall also have such right of
access thereto as may be reasonably necessary to cause the Project to be
properly maintained in accordance with Article V.

including any statement or information in any offering document or materials
regarding the Bonds, the Project or the Company or any certificate executed by
the Company on or as of the date of issuance of the Bonds which, at the time
made, is misleading, untrue or incorrect in any material respect and any untrue
statement or alleged untrue statement of a material fact contained in any
offering material relating to the sale of the Bonds, as from time to time
amended or supplemented, or arising out of or based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary in order to make the statements therein not misleading, or failure to
properly register or otherwise qualify the sale of the Bonds or failure to
comply with any licensing or other law or regulation which would affect the
manner whereby or to whom the Bonds could be sold and the carrying out by the
Company claims arising in connection with the interpretation, performance,

or in connection with any federal or state tax audit, or any questions or other
matters arising under such documents;

      (6) any and all claims arising in connection with the operations of the

      (7) any and all claims arising out of or connected with the Trustee's
acceptance or administration of the trusts created by the Indenture and the
exercise of its powers or duties thereunder or under this Loan Agreement or any
other agreements in connection therewith to which it is a party;

      (8) any statement or information relating to the expenditure of the

      (9) any untrue statement or alleged untrue statement of a material fact
contained in any offering material relating to the sale of the Bonds (as from
time to time amended or supplemented) or arising out of or based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary in order to make the statements therein not
misleading, or failure to properly register or otherwise qualify the sale of the
Bonds or failure to comply with any licensing or other law or regulation which
would affect the manner whereby or to whom the Bonds could be sold.

            Promptly after receipt by any indemnified party of notice of the
commencement of any action with respect to which indemnity may be sought against
the Company under this Section , such person will notify the Company in writing
of the commencement thereof, and, subject to the provisions hereinafter stated,
the Company shall assume the defense of such action (including the employment of
counsel, who shall be counsel reasonably satisfactory to such indemnified party)
and shall assume the payment of all related expenses. Insofar as such action
shall relate to any alleged liability with respect to which indemnity may be
sought against the Company, the Issuer or any such other indemnified person
shall have the right to employ separate counsel in any such action and to
participate in the defense thereof, but the fees and expenses of such counsel
shall not be at the expense of the Company unless the employment of such Counsel
has been specifically authorized by the Company. The Company shall not be liable
to indemnify any person for any settlement of any such action effected without
its consent.

            The provisions of this Section 7.4 shall survive the payment and
discharge of the Bonds. Notwithstanding any transfer of the Project to another
owner, the Company shall remain obligated to indemnify each indemnified party
pursuant to this Section if


                                       28
<PAGE>   33
such subsequent owner fails to indemnify any party entitled to be indemnified
hereunder, unless such indemnified party has consented to such transfer and to
the assignment of the rights and obligations of the Company hereunder.

            Section 7.5 Status of Company.

            The Company may sell or otherwise transfer to another entity all or
substantially all of its assets as an entirety and thereafter dissolve if (i)
the transfer does not cause the interest on the Bonds to become includable in
gross income for purposes of federal income taxation and the Company shall have
provided the Trustee an opinion of Bond Counsel to the Trustee to such effect,
(ii) the Reimbursement Bank has given its written consent to such transfer, and
(iii) the transferee shall assume the obligations of the Company hereunder.

            If a transfer is made as provided in this Section, the provisions of
this Section shall continue in full force and effect and no further
consolidation, merger, sale, or other transfer shall be made except in
compliance with the provisions of this Section .

            Section 7.6 Filing of Financing Statements.

            The Company agrees that it will, at its sole expense, file or cause
to be filed any financing statements and continuation statements to perfect the
security interest granted to the Trustee under the Indenture in this Agreement
and the payments to be made hereunder granted.

            Section 7.7 Assurance of Tax Exemption.

            In order to assure that the interest on the Bonds shall at all times
be free from federal income taxation, the Company represents and covenants with
the Issuer, Trustee and all Holders of the Bonds that it will comply with the
applicable provisions of Sections 103 and 141 through 150 of the Code as
follows:

      (1) the Company will fulfill all conditions specified in Section 144(a)(4)
of the Code, to qualify the Bonds as a $10,000,000 "small issue" thereunder;

      (2) the Company represents that the aggregate amount of any Other Private
Activity Bonds under Section 144(a) of the Code used to finance facilities used
by the Company or a Principal User, or


                                       29
<PAGE>   34
any Related Person, and located in Lincoln, Nebraska, when added to the
principal amount of the Bonds, does not cause the aggregate principal amount of
the Bonds to exceed $10,000,000, and the Company hereby covenants that it will
not take any action with respect to its use of other facilities located within
the jurisdiction of the Issuer which would cause the aggregate principal amount
of the Bonds, together with any Other Private Activity Bonds to exceed the
$10,000,000 limitation imposed by Section 144(a) of the Code;

      (3) the Company will not use (or permit to be used) the Project or use or
invest (or permit to be used or invested) the proceeds of the Bonds or any other
sums treated as "bond proceeds" under Section 148 of the Code, including
"investment proceeds," "invested sinking funds" and "replacement proceeds," in
such a manner as to cause the Bonds to be classified "arbitrage bonds" under
Section 148 of the Code;

      (4) the Company will not cause any Working Capital Expenses to exceed
three percent (3%) of the Net Bond Proceeds; at least ninety-five percent (95%)
of the proceeds of the Bonds will be used for the acquisition or improvement of
land or depreciable property for a "manufacturing facility" as required under
Section 144(a) of the Code; and the proceeds of the Bonds will not be used to
finance any facility which is directly related and ancillary to a "manufacturing
facility" unless: (a) the facilities are located on the same site as the
Manufacturing Facility; (b) not more than 25% of the net proceeds of the Bonds
are used to provide such facilities; (c) manufacturing constitutes substantially
all of the on-site economic activity; and (d) the ancillary facilities are
subordinate and integral to the manufacturing activity;

      (5) in addition to the Bonds, no other obligations have been or are
expected to be issued under Section 103 of the Code for sale at substantially
the same time as the Bonds are sold pursuant to a common plan of marketing and
at substantially the same rate of interest as the Bonds and which are payable in
whole or part by the Company or otherwise have with the Bonds any common or
pooled security for the payment of debt service thereon; and the Company has not
permitted and will not permit any obligation or obligations other than the Bonds
to be issued within the meaning of Section 141 of the Code so as to cause such
obligations to otherwise become part of the same "issue of obligations" of the
Bonds as described in Treasury Regulations Section 1.150-1(c)(1), so as to
impair the


                                       30
<PAGE>   35
exclusion from gross income under Section 103 of the Code of the interest on the
Bonds;

      (6) neither the Company nor any other person who is or will be entitled to
occupy more than ten percent (10%) of the Project measured by value or who is or
will be a Principal User of the Project, has either (a) both (i) guaranteed,
arranged, participated in, or assisted with the issuance or paid any portion of
the cost of issuance of any obligations the proceeds of which are to be used to
finance or refinance any facilities (other than the Project) financed or to be
financed in whole or part from the proceeds of any Private Activity Bonds issued
or sold within three (3) years before or after issuance of, and payable by the
Company or otherwise commonly secured in whole or in part with, the Bonds (the
"Bond Financed Facilities") and (ii) provided any property, or any franchise,
trademark or tradename within the meaning of Section 1253 of the Code, which is
to be used in connection with such Bond Financed Facilities, or (b) acquired a
proprietary interest in or otherwise become entitled to occupy more than ten
percent (10%) (measured by value), or in any other way become a principal user,
of such Bond Financed Facilities; nor shall the Company, nor any other such
Principal User of the Project, or any Related Person thereto, permit such
conditions to occur in the future without first filing with the Trustee an
opinion of Bond Counsel that such conditions will not impair the exclusion from
gross income under Section 103 of the Code of the interest on the Bonds.
Accordingly, neither the Company nor any other such Principal User of the
Project nor any Related Person to the Company or such other Principal User of
the Project is or will, without such prior Bond Counsel opinion, be a Principal
User of any Bond Financed Facilities, other than the Project;

      (7) no portion of the Net Bond Proceeds will be used (i) to acquire or
otherwise provide any private or commercial golf course, country club, massage
parlor, tennis club, skating facility (including roller skating, skateboard and
ice-skating), racquet sports facility (including any handball or racquetball

percent (120%) of the average reasonably expected economic life of the Project
within the meaning of Section 149(e) of the Code;

the Bond Fund or Construction Fund (or other fund created under the Indenture)
shall be invested in investments which cause the Bonds to be federally
guaranteed within the meaning of Section 149(b) of the Code. If at any time the

amounts invested for an initial temporary period until the moneys are needed for
the purpose for which the Bonds were issued, (ii) investments of a bona fide
debt service fund, and (iii) investments of a reserve which meet the requirement
of Section 148(d) of the Code, such excess moneys shall be invested in only

      (17) the Company is the only Test-Period Beneficiary, and the face amount
of the Bonds allocated to the Company as Test-Period Beneficiary, when increased
by any Other Private Activity Bonds outstanding at the Bond Closing and also
allocated to the Company as Test-Period Beneficiary, does not and will not
exceed $40,000,000; and the Company will not permit any other person or entity
to become an owner or other Principal user of the Project if such person or

Private Activity Bonds, together with the face amount of the Bonds allocated to
such Test-Period Beneficiary, exceed $40,000,000, all within the meaning of
Section 144(a)(10) of the Code;


                                       33
<PAGE>   38
      (18) the Company has not permitted and will not permit any Other Private
Activity Bonds to be issued with respect to a single building, an enclosed
shopping mall, or a strip of offices, stores or warehouses, of which the Project
is a part and which use substantial common facilities, so as to (i) treat the
Bonds and such Other Private Activity Bonds as one (1) issue, within the meaning
of Section 144(a)(9) of the Code and (ii) thereby impair the exclusion from
gross income under Section 103 of the Code of the interest on the Bonds;

      (19) at no time during any Bond Year shall the amount invested in taxable
nonpurpose investments with a yield materially higher than the yield on the
Bonds exceed one hundred fifty percent (150%) of the debt service on the Bonds
for the Bond Year, all within the meaning of Section 148(d)(3) of the Code;
provided, however, that the Company may take advantage of exceptions to such
requirement provided for the investment of sums for temporary periods;

      (20) it will not use the proceeds of the Bonds in such a manner as to
cause the Bonds to be "arbitrage bonds" within the meaning of Section 148 of the
Code and applicable Treasury Regulations; and to this end, the Company on behalf
of the Issuer shall pay to the United States, as a rebate, an amount equal to
the sum of (i) the excess of (I) the aggregate amount earned on all nonpurpose
obligations (other than investments attributable to an excess described in this
clause), over (II) the amount which would have been earned if all nonpurpose
obligations were invested at a rate equal to the yield on the Bond plus (ii) any
income attributable to the excess described in clause (i), at the times and in
the amounts required by Section 148 of the Code, all within the meaning of
Section 148 of the Code. The Company and Trustee shall maintain records of the
interest rate borne by the Bonds and the investments of the Construction Fund
and Bond Fund and any cash collateral account created under the Reimbursement
Agreement and earnings thereon in adequate detail to enable the Borrower to
calculate the amount of any rebate required to be made to the United States. The
Company shall pay the rebate to the United States at times and in installments
which satisfy Section 148 of the Code and the regulations, at least once every
five years and within sixty (60) days after the day on which the last of the
Bonds is redeemed. The Company shall retain a Rebate Expert to make calculations
of the amount to be rebated at least every five years, as required by the Code
and the regulations, and the Issuer and Trustee shall be furnished with such
calculations within sixty (60) days of the time they are made. Such calculations
shall be


                                       34
<PAGE>   39
retained until six (6) years after the retirement of the Bonds. The rebate shall
be calculated as provided in the applicable Treasury Regulations, including
taking into account the gain or loss on the disposition of nonpurpose
investments. The Company shall acquire nonpurpose obligations at their fair
market value;

      (21) it is reasonably expected that at least 85% of the spendable proceeds
of the Bonds will be used to carry out the governmental purpose of the Bonds
within the 3-year period beginning on the date of issuance of the Bonds and that
not more than 50% of the proceeds of the Bonds will be invested in nonpurpose
investments (as defined in Section 148(f)(6)(A) of the Code) having a
substantially guaranteed yield for 4 years or more, and therefore the Bonds are
not "hedge bonds" within the meaning of Section 149(g) of the Code; and

      (22) the Company will not otherwise use Bond proceeds, including earnings
thereon, or take, or permit or cause to be taken, any action that would
adversely affect the exemption from federal income taxation of the interest on
the Bonds, nor otherwise omit to take or cause to be taken any action necessary
to maintain such tax exempt status; and, if it should take or permit, or omit to
take or cause to be taken, as appropriate, any such action, the Company shall
take all lawful actions necessary to rescind or correct such actions or
omissions promptly upon having knowledge thereof.

            Section 7.8 Determination of Taxability.

      (1) Promptly after the occurrence of a Determination of Taxability, the
Company shall give written notice to the Issuer and Trustee of the Determination
of Taxability and so long as the Letter of Credit is outstanding, a draw shall
be made under the Letter of Credit as provided in Section 7.2 of the Indenture,
or if no Letter of Credit is outstanding, the Company shall provide to the
Trustee in immediately available funds, an amount which when added to the
amounts on deposit in the Funds, will equal 103 percent of the principal amount
of all the Unpaid Bonds plus accrued interest thereon to the redemption date and
the Bonds shall be redeemed pursuant to Article III of the Indenture.

      (2) Upon a Determination of Taxability the Company shall also pay to the
Trustee an amount equal to the Paying Agent's and Trustee's fees, accrued and to
accrue until final payment and redemption of the Bonds, and all other advances,
fees, costs and


                                       35
<PAGE>   40
expenses reasonably incurred by the Trustee, the Issuer and the Paying Agent,
including Bond Counsel fees and expenses and any other legal fees and expenses.

      (3) If this Agreement has not been terminated under Section 8.4 prior to
the redemption date for the Bonds, this Agreement shall be terminated on said
redemption date and the closing for the termination of this Agreement shall be
completed otherwise as provided for termination of this Agreement upon exercise
of the Company's options under Section 8.4.

      (4) Neither the Company nor any Holder shall be required to contest or
appeal any notice of deficiency, ruling, decision or legislative enactment which
may give rise to a Determination of Taxability; and the expenses of any such
contest or appeal shall be paid by the party initiating the contest or appeal.

their principal amount plus accrued interest, plus premium if any, as set forth

redemption in whole or in part, the Trustee shall draw upon the Letter of Credit
as provided in Section 7.2(1) of the Indenture and if necessary, a Basic Payment
shall be made by the Company as provided in Section 4.2 hereof on said

instruments as the Company reasonably determines are necessary to terminate this
Agreement. All further obligations of the Company hereunder, except as set forth
in Section 10.10, shall thereupon terminate.

            Section 8.3 Direction of Investments.

subject, however, to the further conditions of Article VIII of the Indenture.

            Section 8.4 Termination of Loan Agreement.

            Except during the continuance of an Event of Default, the Company
shall have the option of terminating this Agreement subject to the following
conditions:

      (1) such option may be exercised only with the prior written consent of
the Reimbursement Bank and only if one of the following events shall have
occurred:

            (A) if all Bonds shall have matured or will mature or be subject to
redemption in accordance with their terms on the next succeeding Interest
Payment Date or if provision is otherwise made for payment of all Bonds in such
manner that the Indenture will be discharged under Article IX thereof on or
before the date of termination; or

            (B) if the Project shall have been damaged or destroyed to such
extent that in the reasonable judgment of the Company the Project (i) cannot
reasonably be restored within six (6) months to substantially its condition
immediately preceding such damage or destruction, or (ii) cannot reasonably be
used to carry on the normal operations of the Company for six (6) months, or
(iii) the reasonably estimated cost of restoration exceeds twenty percent (20%)
of the original face amount of the Bonds and is also reasonably estimated to
exceed the proceeds of property insurance payable therefor plus any deductible
amount for which the Company is self-insured, provided that such estimates shall
be approved by the Reimbursement Bank; or

            (C) if by reason of Condemnation, title shall have been taken to all
or substantially all of the Project or the Project Premises, or so much thereof
that in the reasonable judgment of the Company, (i) the Company will be
prevented from carrying on its normal operations for six (6) months, or (ii) the
reasonably estimated cost of restoration of the Project exceeds twenty percent
(20%) of the original face amount of the Bonds and is also reasonably estimated
to exceed the proceeds of the Condemnation award provided that such estimates
shall be approved by the Reimbursement Bank; or

<PAGE>   43
            (D) if as a result of any changes in the Constitution of the State
of Nebraska or the Constitution of the United States of America, or of any
legislative or administrative action, whether state or federal, or of any final
decree, judgment or order of any court or administrative body, whether state or
federal, entered after the contest thereof by the Company in good faith, the
agreements contained in this Agreement shall have become impossible of
performance in accordance with the intent and purposes of the parties as
expressed herein.

      (2) in any of the events stated in subsection (1), clauses (B) through (D)
above, if the Company determines to exercise its option to terminate this
Agreement it must give written notice to the Trustee of its decision to exercise
its option within one hundred twenty (120) days after such event;

      (3) the Company shall give written notice to the Issuer and to the Trustee
of its intention to exercise the option, stating therein a termination date not
less than forty-five (45) nor more than ninety (90) days after the date the
notice is mailed, but in no event prior to date on which all Outstanding Bonds
shall be deemed discharged under Article IX of the Indenture; and the Company
shall make arrangements satisfactory to the Trustee for the giving of any notice
required for redemption of all of the Outstanding Bonds on the date on which the
Bonds are to be redeemed;

      (4) the Trustee shall draw upon the Letter of Credit as provided in
Section 7.2(1) of the Indenture and, if necessary, a Basic Payment shall be made
by the Company as provided in Section 4.2 hereof on the Redemption Date;

      (5) the Company shall pay to the Trustee at least five days prior to the
Discharge Date, an amount equal to the Trustee's and Paying Agent's fees and
expenses under the Indenture, accrued and to accrue until final payment and
redemption of the Bonds and all other advances, fees, costs and expenses,
including but not limited to legal fees, costs and expenses, reasonably incurred
and to be incurred on or before the termination date by the Trustee and Paying
Agent under the Indenture and by the Issuer under this Agreement;

      (6) on the termination date, a closing shall be held at the principal
office of the Trustee, or any other office mutually agreed upon.

            At the closing the Issuer and Trustee shall, upon receipt of the sum
set forth in subsections (4) and (5) above, execute and deliver to the Company
such release and other instruments as the Company reasonably determines is
necessary to terminate this Agreement. All further obligations of the Company
hereunder, except under Section 7.4, 7.7, 7.8, 10.8 and 10.11 shall thereupon
terminate, provided, however, that the Company shall also remain obligated to
pay or reimburse the Issuer and Trustee for the payment of all other fees, costs
and expenses unaccounted for in the sum paid in accordance with subsection (5)
above and reasonably incurred before or subsequent to such closing in connection
with the Bonds.

                         EVENTS OF DEFAULT AND REMEDIES


            Section 9.1 Events of Default.

            Any one or more of the following events is an Event of Default under
this Agreement, and the term "Event of Default," wherever used herein, means any
one of the following events, whatever the reason for such default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body:

      (1) if the Company shall fail to pay any Basic Payments due under this
Agreement;

      (2) if an Act of Bankruptcy occurs;

      (3) if the Company shall fail to pay any Additional Charges on or before
the date that the payment is due, and shall continue to be in arrears for thirty
(30) days after mailing of a notice to it and the Reimbursement Bank by the
Issuer or the Trustee that said Additional Charges have not been received on the
due date;

      (4) if the Company shall fail to observe and perform or shall breach any
other covenant, condition or agreement on its part under this Agreement for a
period of sixty (60) days after mailing of a notice to it by the Issuer or the
Trustee, specifying such default or breach and requesting that it be remedied;
provided that such default may be waived by the Holders of not less than 75% of
the principal amount of the Outstanding Bonds;

      (5) if the Company shall be dissolved or liquidated (other than when a new
entity assumes the obligations of the Company under the conditions permitting
such action contained in Section 7.5); or

      (6) if any representation or warranty made by the Company herein, or by an
officer or representative of the Company in any document or certificate
furnished the Trustee, the Issuer or any Original Purchaser in connection
herewith or therewith or pursuant hereto or thereto, shall prove at any time to
be, in any material respect, incorrect or misleading as of the date made.


                                       41
<PAGE>   46
            Section 9.2 Remedies.

      (1) Whenever any Event of Default specified in Section 9.1(1) hereof shall
have happened and be subsisting the Trustee shall declare all the Basic Payments
payable for the remainder of the Term of this Agreement (an amount equal to that
necessary to pay in full all Outstanding Bonds and the interest thereon upon
acceleration of the Bonds under the Indenture and to pay all other indebtedness
thereunder) to be immediately due and payable whereupon the same shall become
immediately due and payable by the Company; and, so long as the Letter of Credit
is outstanding, under no other circumstances may payment of the Loan be
accelerated on account of an Event of Default unless payment of the Bonds has
also been accelerated under the Indenture;

      (2) Whenever any Event of Default shall have happened and be subsisting,
any one or more of the following remedial steps may also be taken to the extent
permitted by law:

            (A) the Trustee may take whatever action at law or in equity may
appear necessary or appropriate to collect all sums then due and thereafter to
become due, or to enforce performance and observance of any obligation,
agreement, covenant, representation or warranty of the Company, under this
Agreement, or any related instrument; or to otherwise compensate the Issuer,
Trustee or Bondholders for any damages on account of such Event of Default; and

            (B) the Issuer (without the prior written consent of the Trustee if
the Trustee is not enforcing the Issuer's right in a manner to protect the
Issuer or is otherwise taking action that brings adverse consequences to the
Issuer) may take whatever action at law or in equity may appear necessary or
appropriate to enforce its rights of indemnification under Section 7.4 and to
collect all sums then due and thereafter to become due to the Issuer with
respect to its Reserved Rights. Notwithstanding the foregoing, the Issuer is not
precluded from exercising any of its Reserved Rights, even if the Trustee is
exercising the assigned rights of the Issuer hereunder.

            The Reimbursement Bank shall have the right, but not the obligation
to cure any Event of Default on the part of the Company hereunder.


                                       42
<PAGE>   47
            Section 9.3 Disposition of Funds.

            Any amounts collected pursuant to action taken under Section 9.2
(other than sums collected for the Issuer with respect to its Reserved Rights)
shall be applied in accordance with the provisions of the Indenture.

            Section 9.4 Nonexclusive Remedies.

            No remedy herein conferred upon or reserved to the Issuer or Trustee
is intended to be exclusive of any other available remedy or remedies, but each
and every such remedy shall be cumulative and shall be in addition to every
other remedy given under this Agreement or now or hereafter existing at law or
in equity or by statute. No delay or omission to exercise any right or power
accruing upon any Event of Default shall impair any such right or power or shall
be construed to be a waiver thereof, but any such right and power may be
exercised from time to time and as often as may be deemed expedient. In order to
entitle the Issuer (or the Trustee) to exercise any remedy reserved to it in
this Article, it shall not be necessary to give any notice, other than such
notice as may be herein expressly required or be required by law.

            Section 9.5 Attorneys' Fees and Expenses.

            If an Event of Default shall exist under this Agreement and the
Issuer or the Trustee should employ attorneys or incur other expenses for the
collection of any amounts due hereunder, or the enforcement of performance of
any obligation or agreement on the part of the Company, the Company will upon
demand pay to the Issuer or the Trustee the reasonable fees and expenses of such
attorneys and such other expenses so incurred.

            Section 9.6 Effect of Waiver.

            In the event any agreement contained in this Agreement should be
breached by either party and thereafter waived by the other party, such waiver
shall be limited to the particular breach so waived and shall not be deemed to
waive any other breach hereunder.

<PAGE>   48
            Section 9.7 Waiver of Stay or Extension.

            The Company covenants (to the extent that it may lawfully do so)
that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any appraisement, valuation, stay, or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Agreement; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and covenants that it will not hinder, delay or
impede the execution of any power herein granted to the Issuer or the Trustee,
but will suffer and permit the execution of every such power as though no such
law had been enacted.

            Section 9.8 Issuer May File Proofs of Claim.

            In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or the property of the
Company, the Trustee or the Issuer with the prior consent of the Trustee shall
be entitled and empowered, by intervention in such proceeding or otherwise,

      (1) to file and prove a claim and to file such other papers or documents
as may be necessary or advisable in order to have the claims of the Issuer and
the Trustee (for itself and on behalf of Bondholders) (including any claim for
the reasonable compensation, expenses, disbursements and advances of the Issuer
and Trustee, their agents and counsel) allowed in such judicial proceeding, and

      (2) to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same.

            Section 9.9 Restoration of Positions.

            If the Issuer or the Trustee have instituted any proceeding to
enforce any right or remedy under this Agreement, and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Issuer or the Trustee, then and in every such case the Company and the
Issuer shall, subject to any determination in the proceeding, be restored to the
positions they held prior to commencement of such proceedings, and thereafter


                                       44
<PAGE>   49
all rights and remedies of the Issuer shall continue as though no such
proceeding had been instituted.

            Section 9.10 Suits to Protect the Project.

            If the Company shall fail to do so after thirty (30) days prior
written notice from the Issuer or the Trustee, the Trustee shall have power to
institute and to maintain such proceedings as it may deem expedient to prevent
any impairment of the Project or any portion thereof, by any acts which may be
unlawful or in violation of this Agreement, and such suits and proceedings as
the Trustee may deem expedient to protect its interests in the Project or any
portion thereof, including power to institute and maintain proceedings to
restrain the enforcement of or compliance with any 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 or adversely
affect the Project or be prejudicial to the interests of the Bondholders.

            Section 9.11 Performance by Third Parties.

            The Trustee may permit third parties to perform any and all acts or
take such action as may be necessary for and on behalf of the Company to cure
any Event of Default hereunder. The acceptance by the Issuer or the Trustee of
any such performance by third parties shall not in any way diminish or absolve
the Company of primary liability hereunder.

            Section 9.12 Exercise of the Issuer's Remedies by Trustee.

            Whenever any Event of Default shall have happened and be subsisting
the Trustee may, but except as otherwise provided in the Indenture shall not be
obliged to, exercise any or all of the rights of the Issuer under this Article
IX. The Issuer shall not have any obligation to exercise any rights under this
Loan Agreement.

            Section 10.4 Severability.

            In the event any provisions of this Agreement shall be held invalid
or unenforceable by any court of competent jurisdiction, such holding shall not
invalidate or render unenforceable any other provision hereof.

            Section 10.5 Amendments, Changes, and Modifications.

            Except as otherwise provided in this Agreement or in the Indenture,
subsequent to the issuance of the Bonds and before the lien of the Indenture is

effectively amended, changed, modified, altered or terminated without the
written consent of the Trustee, Company and Issuer.

            Section 10.6 Execution Counterparts.

            This Agreement may be simultaneously executed in several
counterparts, each of which shall be an original and all of which shall

            Section 10.7 Required Approvals.

            Consents and approvals required by this Agreement to be obtained
from the Company, the Issuer or the Trustee shall be in writing and shall not be
unreasonably withheld or delayed. Notwithstanding any provisions herein to the
contrary any consent or approval otherwise required by this Indenture to be
obtained from the Reimbursement Bank shall not be required, nor shall the
Trustee be obligated hereunder to comply with any request or direction of the
Reimbursement Bank, if the Letter of Credit is not in full force and effect and
no sums are outstanding under the Letter of Credit, or if the Letter of Credit
is dishonored after presentment of a draft and submission of all documentation
required under the Letter of Credit.

            Section 10.8 Limitation on Issuer Liability.

      (1) It is understood and agreed by the Company and the Holders that no
covenant, provision or agreement of the Issuer herein or in the Bonds or in any
other document executed by the Issuer in connection with the issuance, sale and
delivery of the Bonds, or any obligation herein or therein imposed upon the
Issuer or breach thereof, shall give rise to a pecuniary liability of the


                                       48
<PAGE>   53
Issuer or a charge against its general credit or taxing powers or shall obligate
the Issuer financially in any way except with respect to this Agreement and the
application of revenues therefrom and the proceeds of the Bonds. No failure of
the Issuer to comply with any term, condition, covenant or agreement therein
shall subject the Issuer to liability for any claim for damages, costs or other
financial or pecuniary charges except to the extent that the same can be paid or
recovered from this Agreement or revenues therefrom or proceeds of the Bonds. No
execution on any claim, demand, cause of action or judgment shall be levied upon
or collected from the general credit, general funds or taxing powers of the
Issuer. In making the agreements, provisions and covenants set forth herein, the
Issuer has not obligated itself except with respect to this Agreement and the
application of revenues hereunder as hereinabove provided.

      (2) All obligations of the Issuer incurred hereunder, under the Indenture
and any other document or agreement relating to the Bonds or the Project shall
be limited obligations of the Issuer from the Project and other property pledged
to the payment of the Bonds. The Bonds shall be payable solely from the revenues
and other funds and property pledged under the Indenture for payment of the
Bonds, and no owner of any Bond shall ever have the right to compel any exercise
of the taxing power of the State or any political subdivision or other public
body thereof, nor to enforce the payment hereof against any property of the
State or any such political subdivision or other public body, including the
Issuer except as provided in the Indenture.

      (3) No member, officer, agent, director, employee or attorney of the
Issuer, including any person executing this Loan Agreement on behalf of the
Issuer, shall be liable personally hereunder or for any reason relating to the
issuance of the Bonds. No recourse shall be had for the payment of the principal
of or the interest on the Bonds, or for any claim based therein, or otherwise in
respect thereof, or based on or in respect of this Loan Agreement or any
amendment hereto, against any member, officer, employee, director, agent or
attorney, as such, of the Issuer or any successor whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise, all such liability being, by the acceptance hereof and as
part of the consideration for the issue of the Bonds, expressly waived and
released.


                                       49
<PAGE>   54
      (4) It is expressly understood and agreed by the parties to this Loan
Agreement that:

            (a) The Issuer may rely conclusively on the truth and accuracy of
      any certificate, opinion, notice or other instrument furnished to the
      Issuer by the Trustee, any Bondholder or the Company as to the existence
      of a fact or state of affairs required hereunder to be noticed by the
      Issuer.

            (b) The Issuer shall not be under any obligation to perform any
      record keeping or to provide any legal service, it being understood that
      such services shall be performed or caused to be performed by the Trustee
      or the Company.

            (c) None of the provisions of this Loan Agreement shall require the
      Issuer to expend or risk its own funds (apart from the proceeds of the
      bonds issued under the Indenture) or otherwise endure financial liability
      in the performance of any of its duties or in the exercise of any of its
      rights under this Loan Agreement.

If, notwithstanding the provisions of this Section , the Issuer incurs any
expense, or suffers any losses, claims or damages or incurs any liabilities, the
Company will indemnify and hold harmless the Issuer from the same and will
reimburse the Issuer for any legal or other expenses incurred by the Issuer in

                               PENDING LITIGATION

            On May 1, 1991, the interest payment due on Issuer's $200,000,000
Agricultural Revenue Bonds, Series 1986A and 1986B (the "1986 Bonds") on such
date was not made to the owners of the 1986 Bonds. This default in payment on
the 1986 Bonds was as a result of failure by Executive Life Insurance Company
("Executive Life") to remit to the trustee for the 1986 Bonds amounts due under
the investment agreements provided by Executive Life and securing the 1986
Bonds. Certain proceeds from the 1986 Bonds remain unrepaid from Executive Life
under such investment agreements.

            On April 11, 1991, the Superior Court of the State of California for
the County of Los Angeles issued an order placing Executive Life in
conservatorship. Under the terms of that and subsequent orders, the court
appointed the Insurance Commissioner of the State of California as conservator,
imposed an immediate moratorium on the payment of any benefits or periodic
payments of any kind by Executive Life (except for certain limited hardship
cases) pending further order of the court, and enjoined the officers and
directors of Executive Life from transacting any business on behalf of Executive
Life without the consent of the conservator. That moratorium prevented payment
by Executive Life of amounts due under the investment agreements and resulted in
a failure to make interest payments due on May 1, 1991 on the 1986 Bonds.

            Norwest Bank Minnesota, N.A., the trustee for the 1986 Bonds,
appeared in the conservatorship proceedings and informed the NIFA that it would
take appropriate steps to protect the interest of the holders of the 1986 Bonds.
Among the steps taken was the filing, along with the NIFA, of a complaint for
declaratory relief against Executive Life and the Insurance Commissioner of the
State of California. This action, filed in conjunction with similar complaints
filed by other issuers and trustees with respect to similar bonds, sought a
judgment that the investment agreements issued by Executive Life as investments
of the proceeds of the 1986 Bonds are "insurance policies" and, therefore,
should be treated on a parity with all other insurance policies issued by
Executive Life in a liquidation proceeding. On November 15, 1991, the Superior
Court of California, County of Los Angeles, ruled that the investment agreements
issued by Executive Life (such as the investment agreements issued as
investments of the proceeds of the


                                       C-1

1986 Bonds) are within the class of claims identified by Subdivision (a)(5) of
California Insurance Code Section 1033, as a priority 5 (i.e., equivalent to
other insurance policies, one step above priority 6, the general creditors).
That ruling has been affirmed on appeal and is now final. After a further court
challenge, the rehabilitation plan was modified to treat the bondholders equally
with other policyholders, and, pursuant to that plan, certain payments have been
made to the trustee for the 1986 Bonds on the investment agreements. In the
interim, the trustee has distributed approximately $198.6 million to the 1986
Bondholders. Additional payments to the trustee for the 1986 Bonds may be made
under the rehabilitation plan, but the NIFA is unable to predict either the
likelihood, the amount or the timing of any such payments.
