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

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

Application of Proceeds. Grantor shall promptly notify Lender of any loss or damage to the Property if the estimated cost of repair or replacement exceeds $50,000.00. Lender may make proof of loss if Grantor falls 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 insurer; (2) the risks insured; (3) the amount of the policy; (4) the property Insured, the then current replacement value of such property,

insurance premiums to be paid. The reserve funds shall be held by Lender as a general deposit from Grantor, which Lender may satisfy by payment of the taxes, assessments, and insurance premiums required to be paid by Grantor as they become due.
Lender shall have the right to draw upon the reserve funds to pay such items, and Lender shall not be required to determine the validity or accuracy of any item before paying it. Nothing in the Mortgage shall be construed as requiring Lender to
advance other monies for such purposes, and Lender shall not incur any liability for anything it may do or omit to do with respect to the reserve account. Subject to any limitations set by applicable law, if the reserve funds disclose a shortage or
deficiency, Grantor shall pay such shortage or deficiency as required by Lender. All amounts in the reserve account are hereby pledged to further secure the indebtedness, and Lender is hereby authorized to withdraw and apply such amounts on the
indebtedness upon the occurrence of an Event of Default. Lender shall not be required to pay any interest or earnings on the reserve funds unless required by law or agreed to by Lender in writing. Lender does not hold the reserve funds in trust for
Grantor, and Lender is not Grantors agent for payment of the taxes and assessments required to be paid by Grantor.

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

Breach of Other Agreement. Any breach by Grantor
under the terms of any other agreement between Grantor and Lender that is not

remedied within any grace period provided therein, including without limitation any agreement concerning any indebtedness or other obligation of Grantor to
Lender, whether existing now or later.

Events Affecting Guarantor. Any of the preceding events occurs with respect to any
guarantor, endorser, surety, or accommodation party of any of the indebtedness or any guarantor, endorser, surety, or accommodation party dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any Guaranty of the
indebtedness. In the event of a death, Lender, at its option, may, but shall not be required to, permit the guarantors estate to assume unconditionally the obligations arising under the guaranty in a manner satisfactory to Lender, and, in
doing so, cure any Event of Default.

Adverse Change. A material adverse change occurs in Grantors financial condition,
or Lender believes the prospect of payment or performance of the Indebtedness is impaired.

Insecurity. Lender in good faith
believes itself insecure.

Right to Cure. If any default, other than a default in payment is curable and if Grantor has not
been given a notice of a breach of the same provision of this Mortgage within the preceding twelve (12) months, it may be cured if Grantor, after receiving written notice from Lender demanding cure of such default: (1) cures the default within
fifteen (15) days; or (2) If the cure requires more than fifteen (15) days, immediately initiates steps which Lender deems in Lenders solo discretion to be sufficient to cure the default and thereafter continues and completes all
reasonable and necessary steps sufficient to produce compliance as soon as reasonably practical.

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 without notice to Grantor to declare the entire Indebtedness immediately
due and payable, including any prepayment penalty which Grantor would be required to pay.

UCC Remedies. With respect to all
or any part of the Personal Property, Lender shall have all the rights end 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.

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.

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.

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.

Attorneys 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
