<PAGE>

      COMPLIANCE WITH ENVIRONMENTAL LAWS. Grantor represents and warrants to
      Lender that: (1) During the period of Grantor's ownership of the Property,
      there has been no use, generation, manufacture, storage, treatment,
      disposal, release or threatened release of any Hazardous Substance by any
      person on, under, about or from the Property; (2) Grantor has no knowledge
      of, or reason to believe that there has been, except as previously
      disclosed to and acknowledged by Lender in writing, (a) any breach or
      violation of any Environmental Laws, (b) any use, generation, manufacture,
      storage, treatment, disposal, release or threatened release of any
      Hazardous Substance on, under, about or from the Property by any prior
      owners or occupants of the Property, or (c) any actual or threatened
      litigation or claims of any kind by any person relating to such matters;
      and (3) Except as previously disclosed to and acknowledged by Lender in
      writing, (a) neither Grantor nor any tenant, contractor, agent or other
      authorized user of the Property shall use, generate, manufacture, store,
      treat, dispose of or release any Hazardous Substance on, under, about or
      from the Property; and (b) any such activity shall be conducted in
      compliance with all applicable federal, state, and local laws, regulations
      and ordinances, including without limitation all Environmental Laws.
      Grantor authorizes Lender and its agents to enter upon the Property to
      make such inspections and tests, at Grantor's expense, as Lender may deem
      appropriate to determine compliance of the Property with this section of
      the Mortgage. Any inspections or tests made by Lender shall be for
      Lender's purposes only and shall not be construed to create any
      responsibility or liability on the part of Lender to Grantor or to any
      other person. The representations and warranties contained herein are
      based on Grantor's due diligence in investigating the Property for
      Hazardous Substances. Grantor hereby (1) releases and waives any future
      claims against Lender for indemnity or contribution in the event Grantor
      becomes liable for cleanup or other costs under any such laws; and (2)
      agrees to indemnify and hold harmless Lender against any and all claims,
      losses, liabilities, damages, penalties, and expenses which Lender may
      directly or indirectly sustain or suffer resulting from a breach of this
      section of the Mortgage or as a consequence of any use, generation,
      manufacture, storage, disposal, release or threatened release occurring
      prior to Grantor's ownership or interest in the Property, whether or not
      the same was or should have been known to Grantor. The provisions of this
      section of the Mortgage, including the obligation to indemnify, shall
      survive the payment of the Indebtedness and the satisfaction and
      reconveyance of the lien of this Mortgage and shall not be affected by
      Lender's acquisition of any interest in the Property, whether by
      foreclosure or otherwise.

      NUISANCE, WASTE. Grantor shall not cause, conduct or permit any nuisance
      nor commit, permit, or suffer any stripping of or waste on or to the
      Property or any portion of the Property. Without limiting the generality
      of the foregoing, Grantor will not remove, or grant to any other party the
      right to remove, any timber, minerals (including oil and gas), coal, clay,
      scoria, soil, gravel or rock products without Lender's prior written
      consent.

      REMOVAL OF IMPROVEMENTS. Grantor shall not demolish or remove any
      Improvements from the Real Property without Lender's prior written
      consent. As a condition to the removal of any Improvements, Lender may
      require Grantor to make arrangements satisfactory to Lender to replace
      such Improvements with Improvements of at least equal value.

      LENDER'S RIGHT TO ENTER. Lender and Lender's agents and representatives
      may enter upon the Real Property at all reasonable times to attend to
      Lender's interests and to inspect the Real Property for purposes of
      Grantor's compliance with the terms and conditions of this Mortgage.

      COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS. Grantor shall promptly comply
      with all laws, ordinances, and regulations, now or hereafter in effect, of
      all governmental authorities applicable to the use or occupancy of the
      Property, including without limitation, the Americans With Disabilities
      Act. Grantor may contest in good faith any such law, ordinance, or
      regulation and withhold compliance during any proceeding, including
      appropriate appeals, so long as Grantor has notified Lender in writing
      prior to doing so and so long as, in Lender's sole opinion, Lender's
      interests in the Property are not jeopardized. Lender may require Grantor
      to post adequate security or a surety bond, reasonably satisfactory to
      Lender, to protect Lender's interest.

      DUTY TO PROTECT. Grantor agrees neither to abandon or leave unattended the
      Property. Grantor shall do all other acts, in addition to those acts set
      forth above in this section, which from the character and use of the
      Property are reasonably necessary to protect and preserve the Property.

DUE ON SALE - CONSENT BY LENDER. Lender may, at Lender's option, declare
immediately due and payable all sums secured by this Mortgage upon the sale or
transfer, without Lender's prior written consent, of all or any part of the Real
Property, or any interest in the Real Property. A "sale or transfer" means the
conveyance of Real

                                       2
<PAGE>

Property or any right, title or interest in the Real Property; whether legal,
beneficial or equitable; whether voluntary or involuntary; whether by outright
sale, deed, installment sale contract, land contract, contract for deed,
leasehold interest with a term greater than three (3) years, lease-option
contract, or by sale, assignment, or transfer of any beneficial interest in or
to any land trust holding title to the Real Property, or by any other method of
conveyance of an interest in the Real Property. If any Grantor is a corporation,
partnership or limited liability company, transfer also includes any change in
ownership of more than twenty-five percent (25%) of the voting stock,
partnership interests or limited liability company interests, as the case may
be, of such Grantor. However, this option shall not be exercised by Lender if
such exercise is prohibited by federal law or by Iowa law.

TAXES AND LIENS. The following provisions relating to the taxes and liens on the
Property are part of this Mortgage:

      PAYMENT. Grantor shall pay when due (and in all events prior to
      delinquency) all taxes, payroll taxes, special taxes, assessments, water
      charges and sewer service charges levied against or on account of the
      Property, and shall pay when due all claims for work done on or for
      services rendered or material furnished to the Property. Grantor shall
      maintain the Property free of any liens having priority over or equal to
      the interest of Lender under this Mortgage, except for the Existing
      Indebtedness referred to in this Mortgage or those liens specifically
      agreed to in writing by Lender, and except for the lien of taxes and
      assessments not due as further specified in the Right to Contest
      paragraph.

      RIGHT TO CONTEST. Grantor may withhold payment of any tax, assessment, or
      claim in connection with a good faith dispute over the obligation to pay,
      so long as Lender's interest in the Property is not jeopardized. If a lien
      arises or is filed as a result of nonpayment, Grantor shall within fifteen
      (15) days after the lien arises or, if a lien is filed, within fifteen
      (15) days after Grantor has notice of the filing, secure the discharge of
      the lien, or if requested by Lender, deposit with Lender cash or a
      sufficient corporate surety bond or other security satisfactory to Lender
      in an amount sufficient to discharge the lien plus any costs and
      attorneys' fees, or other charges that could accrue as a result of a
      foreclosure or sale under the lien. In any contest, Grantor shall defend
      itself and Lender and shall satisfy any adverse judgment before
      enforcement against the Property. Grantor shall name Lender as an
      additional obligee under any surety bond furnished in the contest
      proceedings.

      EVIDENCE OF PAYMENT. Grantor shall upon demand furnish to Lender
      satisfactory evidence of payment of the taxes or assessments and shall
      authorize the appropriate governmental official to deliver to Lender at
      any time a written statement of the taxes and assessments against the
      Property.

      NOTICE OF CONSTRUCTION. Grantor shall notify Lender at least fifteen (15)
      days before any work is commenced, any services are furnished, or any
      materials are supplied to the Property, if any mechanic's lien,
      materialmen's lien, or other lien could be asserted on account of the
      work, services, or materials. Grantor will upon request of Lender furnish
      to Lender advance assurances satisfactory to Lender that Grantor can and
      will pay the cost of such Improvements.

PROPERTY DAMAGE INSURANCE. The following provisions relating to insuring the
Property are a part of this Mortgage:

      MAINTENANCE OF INSURANCE. Grantor shall procure and maintain policies of
      fire insurance with standard extended coverage endorsements on a
      replacement basis for the full insurable value covering all Improvements
      on the Real Property in an amount sufficient to avoid application of any
      coinsurance clause, and with a standard mortgagee clause in favor of
      Lender. Grantor shall also procure and maintain comprehensive general
      liability insurance in such coverage amounts as Lender may request with
      Lender being named as additional insureds in such liability Insurance
      policies. Additionally, Grantor shall maintain such other insurance,
      including but not limited to hazard, business interruption and boiler
      insurance as Lender may require. Policies shall be written by such
      insurance companies and in such form as may be reasonably acceptable to
      Lender. Grantor shall deliver to Lender certificates of coverage from each
      insurer containing a stipulation that coverage will not be cancelled or
      diminished without a minimum of ten (10) days' prior written notice to
      Lender and not containing any disclaimer of the insurer's liability for
      failure to give such notice. Each insurance policy also shall include an
      endorsement providing that coverage in favor of Lender will not be
      impaired in any way by any act, omission or default of Grantor or any
      other person. Should the Real Property be located in an area designated by
      the Director of the Federal Emergency Management Agency as a special flood
      hazard area, Grantor agrees to obtain

                                       3
<PAGE>

      and maintain Federal Flood Insurance, if available, within 45 days after
      notice is given by Lender that the Property is located in a special flood
      hazard area, for the full unpaid principal balance of the loan and any
      prior liens on the property securing the loan, up to the maximum policy
      limits set under the National Flood Insurance Program, or as otherwise
      required by Lender, and to maintain such insurance for the term of the
      loan.

      APPLICATION OF PROCEEDS. Grantor shall promptly notify Lender of any loss
      or damage to the Property. Lender may make proof of loss if Grantor fails
      to do so within fifteen (15) days of the casualty. Whether or not Lender's
      security is impaired, Lender may, at Lender's election, receive and retain
      the proceeds of any insurance and apply the proceeds to the reduction of
      the Indebtedness, payment of any lien affecting the Property, or the
      restoration and repair of the Property. If Lender elects to apply the
      proceeds to restoration and repair, Grantor shall repair or replace the
      damaged or destroyed Improvements in a manner satisfactory to Lender.
      Lender shall, upon satisfactory proof of such expenditure, pay or
      reimburse Grantor from the proceeds for the reasonable cost of repair or
      restoration if Grantor is not in default under this Mortgage. Any proceeds
      which have not been disbursed within 180 days after their receipt and
      which Lender has not committed to the repair or restoration of the
      Property shall be used first to pay any amount owing to Lender under this
      Mortgage, then to pay accrued interest, and the remainder, if any, shall
      be applied to the principal balance of the indebtedness. If Lender holds
      any proceeds after payment in full of the Indebtedness, such proceeds
      shall be paid to Grantor as Grantor's interests may appear.

      COMPLIANCE WITH EXISTING INDEBTEDNESS. During the period in which any
      Existing Indebtedness described below is in effect, compliance with the
      insurance provisions contained in the instrument evidencing such Existing
      Indebtedness shall constitute compliance with the insurance provisions
      under this Mortgage, to the extent compliance with the terms of this
      Mortgage would constitute a duplication of insurance requirement. If any
      proceeds from the insurance become payable on loss, the provisions in this
      Mortgage for division of proceeds shall apply only to that portion of the
      proceeds not payable to the holder of the Existing Indebtedness.

      GRANTOR'S REPORT ON INSURANCE. Upon request of Lender, however not more
      than once a year, Grantor shall furnish to Lender a report on each
      existing policy of insurance showing: (1) the name of the insured; (2) the
      risks insured; (3) the amount of the policy; (4) the property insured, the
      then current replacement value of such property, and the manner of
      determining that value; and (5) the expiration date of the policy. Grantor
      shall, upon request of Lender, have an independent appraiser satisfactory
      to Lender determine the cash value replacement cost of the Property.

LENDER'S EXPENDITURES. If any action or proceeding is commenced that would
materially affect Lender's interest in the Property or if Grantor fails to
comply with any provision of this Mortgage or any Related Documents, including
but not limited to Grantor's failure to comply with any obligation to maintain
Existing Indebtedness in good standing as required below, or to discharge or pay
when due any amounts Grantor is required to discharge or pay under this Mortgage
or any Related Documents, Lender on Grantor's behalf may (but shall not be
obligated to) take any action that Lender deems appropriate, including but not
limited to discharging or paying all taxes, liens, security interests,
encumbrances and other claims, at any time levied or placed on the Property and
paying all costs for insuring, maintaining and preserving the Property. All such
expenditures incurred or paid by Lender for such purposes will then bear
interest at the rate charged under the Note or at the highest rate authorized by
law, from the date incurred or paid by Lender to the date of repayment by
Grantor. All such expenses will become a part of the Indebtedness and, at
Lender's option, will (A) be payable on demand; (B) be added to the balance of
the Note and be apportioned among and be payable with any installment payments
to become due during either (1) the term of any applicable insurance policy; or
(2) the remaining term of the Note; or (C) be treated as a balloon payment which
will be due and payable at the Note's maturity. The Mortgage also will secure
payment of these amounts. Such right shall be in addition to all other rights
and remedies to which Lender may be entitled upon Default.

WARRANTY; DEFENSE OF TITLE. The following provisions relating to ownership of
the Property are a part of this Mortgage:

      TITLE. Grantor warrants that: (a) Grantor holds good and marketable title
      of record to the Property in fee simple, free and clear of all liens and
      encumbrances other than those set forth in the Real Property description
      or in the Existing Indebtedness section below or in any title insurance
      policy, title report, or final title opinion issued in favor of, and
      accepted by, Lender in connection with this Mortgage, (b) Grantor has the
      full right, power, and authority to execute and deliver this Mortgage to
      Lender, and (c) the liens granted hereby are not the type of

                                       4
<PAGE>

      lien referred to in Chapter 575 of the Iowa Code Supplement, as now
      enacted or hereafter modified, amended or replaced. Grantor, for itself
      and all persons claiming by, through or under Grantor, agrees that it
      claims no lien or right to a lien of the type contemplated by Chapter 575
      or any other chapter of the Code of Iowa and further waives all notices
      and rights pursuant to said law with respect to the liens hereby granted,
      and represents and warrants that it is the sole party entitled to do so
      and agrees to indemnify and hold harmless Lender from any loss, damage,
      and costs, including reasonable attorneys' fees, threatened or suffered by
      Lender arising either directly or indirectly as a result of any claim of
      the applicability of said law to the liens hereby granted.

      DEFENSE OF TITLE. Subject to the exception in the paragraph above, Grantor
      warrants and will forever defend the title to the Property against the
      lawful claims of all persons. In the event any action or proceeding is
      commenced that questions Grantor's title or the interest of Lender under
      this Mortgage, Grantor shall defend the action at Grantor's expense.
      Grantor may be the nominal party in such proceeding, but Lender shall be
      entitled to participate in the proceeding and to be represented in the
      proceeding by counsel of Lender's own choice, and Grantor will deliver, or
      cause to be delivered, to Lender such instruments as Lender may request
      from time to time to permit such participation.

      COMPLIANCE WITH LAWS. Grantor warrants that the Property and Grantor's use
      of the Property complies with all existing applicable laws, ordinances,
      and regulations of governmental authorities.

      SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations,
      warranties, and agreements made by Grantor in this Mortgage shall survive
      the execution and delivery of this Mortgage, shall be continuing in
      nature, and shall remain in full force and effect until such time as
      Grantor's Indebtedness shall be paid in full.

EXISTING INDEBTEDNESS. The following provisions concerning Existing Indebtedness
are a part of this Mortgage:

      EXISTING LIEN. The lien of this Mortgage securing the Indebtedness may be
      secondary and inferior to the lien securing payment of an existing
      obligation. The existing obligation has a current principal balance of
      approximately $2,319,443.00. Grantor expressly covenants and agrees to
      pay, or see to the payment of, the Existing Indebtedness and to prevent
      any default on such indebtedness, any default under the instruments
      evidencing such indebtedness, or any default under any security documents
      for such indebtedness.

      NO MODIFICATION. Grantor shall not enter into any agreement with the
      holder of any mortgage, deed of trust, or other security agreement which
      has priority over this Mortgage by which that agreement is modified,
      amended, extended, or renewed without the prior written consent of Lender.
      Grantor shall neither request nor accept any future advances under any
      such security agreement without the prior written consent of Lender.

CONDEMNATION. The following provisions relating to condemnation proceedings are
a part of this Mortgage:

      PROCEEDINGS. If any proceeding in condemnation is filed, Grantor shall
      promptly notify Lender in writing, and Grantor shall promptly take such
      steps as may be necessary to defend the action and obtain the award.
      Grantor may be the nominal party in such proceeding, but Lender shall be
      entitled to participate in the proceeding and to be represented in the
      proceeding by counsel of its own choice, and Grantor will deliver or cause
      to be delivered to Lender such instruments and documentation as may be
      requested by Lender from time to time to permit such participation.

      APPLICATION OF NET PROCEEDS. If all or any part of the Property is
      condemned by eminent domain proceedings or by any proceeding or purchase
      in lieu of condemnation, Lender may at its election require that all or
      any portion of the net proceeds of the award be applied to the
      Indebtedness or the repair or restoration of the Property. The net
      proceeds of the award shall mean the award after payment of all reasonable
      costs, expenses, and attorneys' fees incurred by Lender in connection with
      the condemnation.

provisions relating to governmental taxes, fees and charges are a part of this

      subsequent to the date of this Mortgage, this event shall have the same
      effect as an Event of Default, and Lender may exercise any or all of its

      matters referred to in the preceding paragraph.

FULL PERFORMANCE. If Grantor pays all the Indebtedness when due, and otherwise
performs all the obligations imposed upon Grantor under this Mortgage, Lender
shall execute and deliver to Grantor a suitable satisfaction of this Mortgage

evidencing Lender's security interest in the Rents and the Personal Property.
Grantor will pay, if permitted by applicable law, any reasonable termination fee
as determined by Lender from time to time.

EVENTS OF DEFAULT. Each of the following, at Lender's option, shall constitute

      obligation, covenant or condition contained in this Mortgage or in any of
      the Related Documents or to comply with or to perform any term,

      Lender and Grantor.

      FALSE STATEMENTS. Any warranty, representation or statement made or
      furnished to Lender by Grantor or on Grantor's behalf under this Mortgage
      or the Related Documents is false or misleading in any material respect,
      either now or at the time made or furnished or becomes false or misleading
      at any time thereafter.

      DEFECTIVE COLLATERALIZATION. This Mortgage or any of the Related Documents
      ceases to be in full force and effect (including failure of any collateral
      document to create a valid and perfected security interest or lien) at any
      time and for any reason.

      DEATH OR INSOLVENCY. The dissolution of Grantor's (regardless of whether

      includes a garnishment of any of Grantor's accounts, including deposit
      accounts, with Lender. However, this Event of Default shall not apply if
      there is a good faith dispute by Grantor as to the validity or
      reasonableness of the claim which is the basis of the creditor or
      forfeiture proceeding and if Grantor gives Lender written notice of the
      creditor or forfeiture proceeding and deposits with Lender monies or a
      surety bond for the creditor or forfeiture proceeding, in an amount
      determined by Lender, in its sole discretion, as being an adequate reserve
      or bond for the dispute.

      interest on the Existing Indebtedness is not made within the time required

      whether existing now or later.

      or liability under, any Guaranty of the Indebtedness.

      INSECURITY. Lender in good faith believes itself insecure.

RIGHTS AND REMEDIES ON DEFAULT. Upon the occurrence of an Event of Default and
at any time thereafter, Lender, at Lender's option, may exercise any one or more
of the following rights and remedies, in addition to any other rights or
remedies provided by law:

      ACCELERATE INDEBTEDNESS. Lender shall have the right at its option to
      declare the entire Indebtedness immediately due and payable, including any
      prepayment penalty which Grantor would be required to pay without notice,
      except as may be expressly required by applicable law.

      UCC REMEDIES. With respect to all or any part of the Personal Property,
      Lender shall have all the rights and remedies of a secured party under the
      Uniform Commercial Code.

      COLLECT RENTS. Lender shall have the right, without notice to Grantor, to
      take possession of the Property and collect the Rents, including amounts
      past due and unpaid, and apply the net proceeds, over and above Lender's
      costs, against the Indebtedness. In furtherance of this right, Lender may
      require any tenant or other user of the Property to make payments of rent
      or use fees directly to Lender. If the Rents are collected by Lender, then
      Grantor irrevocably designates Lender as Grantor's attorney-in-fact to
      endorse instruments received in payment thereof in the name of Grantor and
      to negotiate the same and collect the proceeds. Payments by tenants or
      other users to Lender in response to Lender's demand shall satisfy the
      obligations for which the payments are made, whether or not any proper
      grounds for the demand existed. Lender may exercise its rights under this
      subparagraph either in person, by agent, or through a receiver.

      APPOINT RECEIVER. Lender shall have the right to have a receiver appointed
      to take possession of all or any part of the Property, with the power to
      protect and preserve the Property, to operate the Property preceding
      foreclosure or sale, and to collect the Rents from the Property and apply
      the proceeds, over and above the cost of the receivership, against the
      Indebtedness. The receiver may serve without bond if permitted by law.
      Lender's right to the appointment of a receiver shall exist whether or not
      the apparent value of the Property exceeds the Indebtedness by a
      substantial amount. Employment by Lender shall not disqualify a person
      from serving as a receiver.

      JUDICIAL FORECLOSURE. Lender may obtain a judicial decree foreclosing
      Grantor's interest in all or any part of the Property.

      NONJUDICIAL FORECLOSURE. Lender may exercise the right to non-judicial
      foreclosure pursuant to Iowa Code Section 654.18 and Chapter 655A as now
      enacted or hereafter modified, amended or replaced.

      DEFICIENCY JUDGMENT. If permitted by applicable law, Lender may obtain a
      judgment for any deficiency remaining in the Indebtedness due to Lender
      after application of all amounts received from the exercise of the rights
      provided in this section.

      TENANCY AT SUFFERANCE. If Grantor remains in possession of the Property
      after the Property is sold as provided above or Lender otherwise becomes
      entitled to possession of the Property upon default of Grantor, Grantor
      shall become a tenant at sufferance of Lender or the purchaser of the
      Property and shall, at Lender's option, either (1) pay a reasonable rental
      for the use of the Property, or (2) vacate the Property immediately upon
      the demand of Lender. This paragraph is subject to any rights of Grantor,
      under Iowa law, to remain in possession of the Property during a
      redemption period.

                                       8
<PAGE>

      OTHER REMEDIES. Lender shall have all other rights and remedies provided
      in this Mortgage or the Note or available at law or in equity.

      SALE OF THE PROPERTY. To the extent permitted by applicable law, Grantor
      hereby waives any and all right to have the Property marshalled. In
      exercising its rights and remedies, Lender shall be free to sell all or
      any part of the Property together or separately, in one sale or by
      separate sales. Lender shall be entitled to bid at any public sale on all
      or any portion of the Property.

      NOTICE OF SALE. Lender shall give Grantor reasonable notice of the time
      and place of any public sale of the Personal Property or of the time after
      which any private sale or other intended disposition of the Personal
      Property is to be made. Reasonable notice shall mean notice given at least
      ten (10) days before the time of the sale or disposition. Any sale of the
      Personal Property may be made in conjunction with any sale of the Real
      Property.

      SHORTENED REDEMPTION. Grantor hereby agrees that, in the event of
      foreclosure of this Mortgage, Lender may, at Lender's sole option, elect
      to reduce the period of redemption pursuant to Iowa Code Sections 628.26,
      628.27, or 628.28, or any other Iowa Code Section, to such time as may be
      then applicable and provided by law.

      ELECTION OF REMEDIES. Election by Lender to pursue any remedy shall not
      exclude pursuit of any other remedy, and an election to make expenditures
      or to take action to perform an obligation of Grantor under this Mortgage,
      after Grantor's failure to perform, shall not affect Lender's right to
      declare a default and exercise its remedies. Nothing under this Mortgage
      or otherwise shall be construed so as to limit or restrict the rights and
      remedies available to Lender following an Event of Default, or in any way
      to limit or restrict the rights and ability of Lender to proceed directly
      against Grantor and/or against any other co-maker, guarantor, surety or
      endorser and/or to proceed against any other collateral directly or
      indirectly securing the Indebtedness.

      ATTORNEYS' FEES; EXPENSES. If Lender institutes any suit or action to
      enforce any of the terms of this Mortgage, Lender shall be entitled to
      recover such sum as the court may adjudge reasonable as attorneys' fees at
      trial and upon any appeal. Whether or not any court action is involved,
      and to the extent not prohibited by law, all reasonable expenses Lender
      incurs that in Lender's opinion are necessary at any time for the
      protection of its interest or the enforcement of its rights shall become a
      part of the Indebtedness payable on demand and shall bear interest at the
      Note rate from the date of the expenditure until repaid. Expenses covered
      by this paragraph include, without limitation, however subject to any
      limits under applicable law, Lender's attorneys' fees and Lender's legal
      expenses, whether or not there is a lawsuit, including attorneys' fees and
      expenses for bankruptcy proceedings (including efforts to modify or vacate
      any automatic stay or injunction), appeals, and any anticipated post
      judgment collection services, the cost of searching records, obtaining
      title reports (including foreclosure reports), surveyors' reports, and
      appraisal fees and title insurance, to the extent permitted by applicable
      law. Grantor also will pay any court costs, in addition to all other sums
      provided by law.

limitation any notice of default and any notice of sale shall be given in

beginning of this Mortgage. Any party may change its address for notices under
this Mortgage by giving formal written notice to the other parties, specifying
that the purpose of the notice is to change the party's address. For notice
purposes, Grantor agrees to keep Lender informed at all times of Grantor's
current address. Unless otherwise provided or required by law, if there is more
than one Grantor, any notice given by Lender to any Grantor is deemed to be
notice given to all Grantors.

      TO LENDER AND, TO THE EXTENT NOT PREEMPTED BY FEDERAL LAW, THE LAWS OF THE
      STATE OF OKLAHOMA WITHOUT REGARD TO ITS CONFLICTS OF LAW PROVISIONS.
      HOWEVER, IF THERE EVER IS A QUESTION ABOUT WHETHER ANY PROVISION OF THIS

      NO WAIVER BY LENDER. Lender shall not be deemed to have waived any rights
      under this Mortgage unless such waiver is given in writing and signed by
      Lender. No delay or omission on the part of Lender in exercising any right
      shall operate as a waiver of such right or any other right. A waiver by

      SEVERABILITY. If a court of competent jurisdiction finds any provision of
      this Mortgage to be illegal, invalid, or unenforceable as to any
      circumstance, that finding shall not make the offending provision illegal,
      invalid, or unenforceable as to any other circumstance. If feasible, the
      offending provision shall be considered modified so that it becomes legal,
      valid and enforceable. If the offending provision cannot be so modified,
      it shall be considered deleted from this Mortgage. Unless otherwise
      required by law, the illegality, invalidity, or unenforceability of any
      provision of this Mortgage shall not affect the legality, validity or
      enforceability of any other provision of this Mortgage.

      MERGER. There shall be no merger of the interest or estate created by this
      Mortgage with any other interest or estate in the Property at any time
      held by or for the benefit of Lender in any capacity, without the written
      consent of Lender.

      SUCCESSORS AND ASSIGNS. Subject to any limitations stated in this Mortgage
      on transfer of Grantor's interest, this Mortgage shall be binding upon and
      inure to the benefit of the parties, their successors and assigns. If
      ownership of the Property becomes vested in a person other than Grantor,
      Lender, without notice to Grantor, may deal with Grantor's successors with
      reference to this Mortgage and the Indebtedness by way of forbearance or
      extension without releasing Grantor from the obligations of this Mortgage
      or liability under the Indebtedness.

      TIME IS OF THE ESSENCE. Time is of the essence in the performance of this
      Mortgage.

      WAIVE JURY. ALL PARTIES TO THIS MORTGAGE HEREBY WAIVE THE RIGHT TO ANY
