II.

 

All rents, issues,
profits, condemnation awards, insurance proceeds, revenues and income arising from the ownership or operation of the Land and
the Improvements and all proceeds and products thereof (herein collectively called “Revenues and Income”). 

 

To Have and To Hold
the Lands and Improvements (together the “Mortgaged Property”), and the Revenues and Income therefrom, together with
all privileges, hereditaments and appurtenances thereunto now or hereafter belonging or in anywise appertaining, and the proceeds
thereof unto Mortgagee forever: provided, nevertheless, that this Mortgage is upon the express condition that if Mortgagor shall
cause to be paid to Mortgagee as and when due and payable the principal of, premium, if any, and interest on the Note, and all
other Indebtedness, and if Mortgagor shall also keep and perform each and every covenant and agreement of Mortgagor herein contained,
then, this Mortgage and the estate hereby granted shall cease and be and

 

    	-2-

    	 

    

 

become
void and shall be released of record at the expense of Mortgagor; otherwise this Mortgage shall be and remain in full force and
effect. 

 

Mortgagor represents,
warrants and covenants to and with Mortgagee that it is lawfully seized of the Land in fee simple and has good right and full
power and authority to execute this Mortgage and to mortgage the Mortgaged Property: that Mortgagor owns the Mortgaged Property
free from all liens, security interests and encumbrances with the exception of those permitted encumbrances set forth in Exhibit
B attached hereto (the “Prior Permitted Encumbrances”); that Mortgagor will warrant and defend its title to the
Mortgaged Property and the lien and priority of this Mortgage against all claims and demands of all persons whomsoever, whether
now existing or hereafter arising, with the exception of the Prior Permitted Encumbrances; and that all buildings and improvements
now or hereafter located on the Land are, or will be, located entirely within the boundaries of the Land. The covenants and warranties
of this paragraph shall survive foreclosure of this Mortgage and shall run with the Land. 

 

Mortgagor further
covenants and agrees as follows:

 

1.          Payment
of the Note. Mortgagor shall duly and punctually pay the principal of and interest on the Note, together with any prepayment
charges and late charges provided for in the Note, in accordance with the terms of the Note, and pay all other Indebtedness, when
and as due and payable. The provisions of the Note are hereby incorporated by reference into this Mortgage as fully as if set
forth at length herein. 

 

2.          Status
of Mortgagor. The Mortgagor’s exact legal name is correctly set forth at the end of this Mortgage Instrument. The Mortgagor,
if applicable, is an organization of the type specified in the first paragraph of this Mortgage. The Mortgagor is incorporated
in or organized under the laws of the state specified in the first paragraph of this Mortgage. The Mortgagor will not cause or
permit any change to be made in its name, identity or corporate or partnership structure, including, any transfer, assignment,
sale or encumbrance with respect to any partnership interest or corporate shares of Mortgagor whether by Mortgagor or any of its
partners or shareholders unless the Mortgagor shall have first notified the Mortgagee in writing of such change at least 30 days
prior to the effective date of such change, and shall have first taken all action required by the Mortgagee for the purpose of
perfecting or protecting the lien and security interest of the Mortgagee. The Mortgagor’s principal place of business and chief
executive office, and the place where Mortgagor keeps its books and records, including recorded data of any kind or nature, regardless
of the medium or recording, including software, writings, plans, specifications and schematics, has been for the preceding four
months (or, if less, the entire period of the existence of the Mortgagor) and will continue to be the address of the Mortgagor
set forth at the end of the Mortgage (unless the Mortgagor notifies the Mortgagee in writing at least 30 days prior to the date
of such change). The Mortgagor’s organizational identification number, if any, assigned by the state of incorporation or organization
is correctly set forth in paragraph 30 of this Mortgage. The Mortgagor shall promptly notify the Mortgagee of any change in its
organizational identification number. If the Mortgagor does not now have an

 

    	-3-

    	 

    

 

organizational identification
number and later obtains one, the Mortgagor promptly shall notify the Mortgagee of such organizational identification number. 

 

3.          Insurance. 

 

a.          Mortgagor
shall keep the buildings, structures, fixtures, personal property and other improvements now existing or hereafter erected or
placed on the Land insured against loss by fire, perils of extended coverage, and such other hazards, casualties and contingencies,
on a “Special Forms Peril” form, for the full replacement cost, with coverage for demolition and increased costs of
construction, and Equipment Breakdown Insurance, for such periods with policies in such form as may be required by Mortgagee.
All insurance shall be carried in companies approved by Mortgagee and the policies and renewals thereof shall (i) contain a waiver
of defense based on coinsurance, (ii) be constantly assigned and pledged to and held by Mortgagee as additional security for the
Indebtedness secured by this Mortgage, (iii) contain an agreement of the insurer that it will not cancel the policy except after
thirty (30) days prior written notice to Mortgagee, (iv) contain a standard or union mortgage clause (sometimes known as the New
York Standard Mortgage Clause), creating a separate contract between the insurer and Mortgagee, in favor of and in form acceptable
to Mortgagee, (v) include effective waivers by the insurer of all claims for insurance premiums against Mortgagee, (vi) provide
that any losses shall be payable notwithstanding (1) any act of negligence of Mortgagor or Mortgagee, (2) any foreclosure or other
proceedings or notice of sale relating to the Mortgaged Property, or (3) any change in the title to or ownership of the Mortgaged
Property, and (vii) shall be reasonably satisfactory to Mortgagee in all other respects. In default thereof, Mortgagee may secure
such insurance and the amount paid therefor shall become immediately due and payable with interest at the rate provided in the
Note and shall be secured by this Mortgage. Notwithstanding anything herein to the contrary, it shall be Mortgagor’s and not Mortgagee’s
responsibility to maintain insurance coverage. In event of loss Mortgagor will give immediate notice by mail to Mortgagee, who
may make proof of loss if not made promptly by Mortgagor. Mortgagor hereby authorizes Mortgagee to settle and compromise all claims
on such policies and hereby authorizes and directs each insurance company concerned to make payment for any such loss directly
to Mortgagee instead of to Mortgagor and Mortgagee jointly. In the event that the loss exceeds $20,000.00, the insurance proceeds,
or any part thereof, may be applied by Mortgagee at its option either to the reduction of the Indebtedness hereby secured (provided
that in the event such application does not pay said Indebtedness in full, any such partial payment shall not affect or suspend
remaining installment payments of principal and interest due under the Note) or to the restoration or repair of the property damaged.
The original of all policies of insurance shall be deposited with Mortgagee. In lieu of a deposit of the original policy, Mortgagor
may provide a certificate of insurance and a certified copy of the insuring provisions of a master policy of insurance covering
the Mortgaged Property. Mortgagor shall provide Mortgagee upon request with appropriate evidence that all premiums on said policies
of insurance have been paid. In the event of foreclosure of this Mortgage, all right, title and interest of Mortgagor in and to
any insurance policies then in force and proceeds of insurance not yet paid for loss or damage shall pass to the purchaser at
the foreclosure sale.

 

    	-4-

    	 

    

  

			Notwithstanding the provisions contained in Paragraphs 3 and 13 of this Mortgage to the contrary,
if all or a portion of the Improvements is taken by eminent domain, or destroyed or damaged by fire or other casualty, Mortgagor
may elect to have the proceeds of insurance or the condemnation award, less the portion thereof applied to the costs of obtaining
such proceeds or award (the “Net Proceeds”) applied to replace, repair, rebuild, and restore the Mortgaged Property to
substantially the same condition as existed before the taking or event causing the damage or destruction, with such changes, alterations,
and modifications as may be desired by Mortgagor and approved by Mortgagee, and will be suitable for continued operation of the
Mortgaged Property for the business purposes of Mortgagor, subject to the following conditions:

 

		(i)	No uncured Event of Default shall exist hereunder on the
date any disbursement of Net Proceeds is requested by Mortgagor;

 

		(ii)	The appraised value of the Land and improvements after
such restoration or repair shall not have been reduced below the appraised value of the Mortgaged Property as of the date of this
Mortgage; and

 

		(iii)	All Net Proceeds shall be paid to Mortgagee and shall
be disbursed by an escrow agent designated by Mortgagee, in the manner consistent with disbursements of construction proceeds.
Prior to the first disbursement of Net Proceeds, Mortgagor shall provide Mortgagee with plans and specifications for the restoration
reasonably acceptable to Mortgagee, a copy of the construction contract with a contractor reasonably acceptable to Mortgagee providing
for the necessary reconstruction and repair, insurance coverage commonly required for new construction, and a sworn cost statement
itemizing all costs of the restoration and demonstrating that the Net Proceeds are sufficient to pay such costs. If the Net Proceeds
are insufficient to complete restoration, Mortgagor shall deposit the difference with the escrow agent prior to the first disbursement
of Net Proceeds.

  

b.          Mortgagor
shall also maintain public liability, including personal injury and property damage, insurance applicable to the Mortgaged Property
in such amounts as are usually carried by persons operating similar properties in the same general locality but in any event with
limits of liability not less than $1,000,000.00 combined single limit, naming Mortgagee as an additional insured, and containing
an agreement of the insurer that it will not cancel the policy except after thirty (30) days prior written notice to Mortgagee. 

 

c.          If
the Land or any part thereof is located in a designated official flood-hazard area, Mortgagor shall also maintain flood insurance
insuring the Mortgaged Property now existing or hereafter erected on the Land in an amount equal to the actual replacement cost
thereof or to the maximum limit of coverage made available with respect to the Mortgaged

 

    	-5-

    	 

    

 

Property under the Federal
Flood Disaster Protection Act of 1973 (P.L. 93-234), as amended, whichever is less. 

 

4.          Payment
of Taxes, Assessments and Other Charges. Subject to required payments under paragraph 5 hereof and to paragraph 8 relating
to contests, Mortgagor shall pay before a penalty might attach for nonpayment thereof, all taxes and assessments and all other
charges whatsoever levied upon or assessed or placed against the Mortgaged Property, except that assessments may be paid in installments
so long as no fine or penalty is added to any installment for the nonpayment thereof. Mortgagor shall likewise pay all taxes,
assessments and other charges, levied upon or assessed, placed or made against, or measured by, this Mortgage, or the recordation
hereof, or the Indebtedness secured hereby, provided that Mortgagor shall not be obliged to pay such tax, assessment or charge
if such payment would be contrary to law or would result in the payment of an unlawful rate of interest on the Indebtedness secured
hereby; and provided further that nothing herein contained shall be construed as requiring Mortgagor to pay any net income, profits
or revenue taxes of Mortgagee. Mortgagor shall promptly furnish to Mortgagee all notices received by Mortgagor of amounts due
under this paragraph and in the event Mortgagor shall make payment directly, Mortgagor shall promptly furnish to Mortgagee receipts
evidencing such payments.

 

5.          Fund
for Taxes, Assessments and Insurance.

 

a.          Unless
waived in writing by Mortgagee, Mortgagor shall pay to Mortgagee on the day installments of principal and interest are payable
under the Note, or on such other day of the month Mortgagee may direct until the Indebtedness is paid in full, a sum equal to
one-twelfth of the yearly taxes and assessments levied against the Mortgaged Property, plus one-twelfth of the annual premiums
for the insurance required by paragraph 3 hereof, all as estimated initially and from time to time by Mortgagee, to be applied
by Mortgagee to pay said taxes, assessments and insurance premiums (such amounts being hereafter referred to as the “Funds”).
Mortgagee shall apply the Funds to pay said taxes, assessments and insurance premiums so long as the amount of Funds held by Mortgagee
is sufficient to make such payments. No earnings or interest shall be payable to Mortgagor on the Funds. Such Funds shall not
be, nor be deemed to be, trust funds, and Mortgagee shall have the right to hold the Funds in any manner Mortgagee elects and
may commingle the Funds with other monies held by Mortgagee. 

 

b.          If the amount of the Funds held
by Mortgagee shall exceed at any time the amount deemed necessary by Mortgagee to provide for the payment of taxes, assessments
and insurance premiums, such excess shall, at the option of Mortgagee, either be promptly repaid to Mortgagor or be credited to
Mortgagor on the next monthly installments of Funds due. If at any time the amount of the Funds held by Mortgagee shall be less
than the amount deemed necessary by Mortgagee to pay taxes, assessments and insurance premiums as they fall due, Mortgagor shall
promptly pay to Mortgagee any amount necessary to make up the deficiency upon notice from Mortgagee to Mortgagor requesting payment
thereof. The Funds are pledged as additional security for the Indebtedness.

 

    	-6-

    	 

    

  

c.          Upon
the occurrence of any Event of Default (as defined in Paragraph 21 hereof), Mortgagee may apply in any order as Mortgagee shall
determine in its sole discretion, any Funds held by Mortgagee at the time of application to pay taxes, assessments and insurance
premiums which are then or will thereafter become due or as a credit against the Indebtedness. Upon payment in full of all Indebtedness,
Mortgagee shall promptly refund any Funds held by Mortgagee.

 

d.          Any
waiver by Mortgagee of the requirements of this paragraph 5 may be revoked without prior notice by Mortgagee at any time for any
reason. 

 

6.          Payment
of Utility Charges. Subject to paragraph 8 relating to contests, Mortgagor shall pay all charges (exclusive of charges which
are the obligations of tenants to pay) made by utility companies, whether public or private, for electricity, gas, heat, water
or sewer, furnished or used in connection with the Mortgaged Property or any part thereof, and shall, upon written request of
Mortgagee, furnish proper receipts evidencing such payment. 

 

7.          Liens.
Subject to paragraph 8 hereof relating to contests, Mortgagor shall not create, incur or suffer to exist any lien, encumbrance
or charge filed of record against the Mortgaged Property or the Revenues and Income or any part thereof, other than the lien of
current real estate taxes and installments of special assessments with respect to which no penalty is yet payable and the Prior
Permitted Encumbrances. Mortgagor shall pay, when due, the claims of all persons supplying labor or materials to or in connection
with the Mortgaged Property. Mortgagor shall pay all expenses and attorney fees incurred by Mortgagee by reason of litigation
with any third party for the protection of the lien of this Mortgage or the preservation of the Mortgaged Property. 

 

8.          Permitted
Contests. Mortgagor shall not be required to (i) pay any tax, assessment or other charge referred to in paragraph 4 hereof,
(ii) pay any charge referred to in paragraph 6 hereof, (iii) discharge or remove any lien, encumbrance or charge referred to in
paragraph 7 hereof, or (iv) comply with any statute, law, rule, regulation or ordinance referred to in paragraph 9 hereof, so
long as Mortgagor shall (a) contest, in good faith, the existence, amount or the validity thereof, the amount of damages caused
thereby or the extent of Mortgagor’s liability therefor, by appropriate proceedings which shall operate during the pendency thereof
to prevent (A) the collection of, or other realization upon the tax, assessment, charge or lien, encumbrance or charge so contested,
(B) the sale, forfeiture or loss of the Mortgaged Property or any part thereof, and (C) any interference with the use or occupancy
of the Mortgaged Property or any part thereof, and (b) shall give such security to Mortgagee as may be reasonably demanded by
Mortgagee to insure compliance with the foregoing provisions of this paragraph 8. Mortgagor shall give prompt written notice to
Mortgagee of the commencement of any contest referred to in this paragraph 8. 

 

9.          Preservation and Maintenance
of Mortgaged Property. Mortgagor (i) shall keep the buildings and other Improvements now or hereafter erected on the Land in
safe and good repair and condition, ordinary depreciation excepted, (ii) shall constantly maintain the parking

 

    	-7-

    	 

    

 

and landscaped areas
of the Mortgaged Property, (iii) shall not commit waste or permit impairment or deterioration of the Mortgaged Property, (iv)
shall not alter or permit the alteration by any tenant of the design or structural character of any building now or hereafter
erected on the Land or hereafter construct, or permit any tenant to construct additions to existing buildings or additional buildings
on the Land, without the prior written consent of Mortgagee, (v) shall not remove or permit removal from the Land of any of the
fixtures or personal property included in the Mortgaged Property unless the same is immediately replaced with like property of
at least equal value and utility, and this Mortgage becomes a valid first lien on such property, and (vi) shall not remove or
permit removal from the Land of any buildings or other structures, nor do any act that would impair or lessen the value of the
Mortgaged Property without the prior written consent of Mortgagee. Mortgagor covenants, warrants and represents that Mortgagor
is in compliance with all present, and will promptly comply with all future laws, ordinances, rules and regulations of any governmental
authority affecting the Mortgaged Property. 

 

10.          Right
of Mortgagee to Enter. Mortgagor will permit Mortgagee and its agent to enter and to authorize others to enter upon any or
all of the Mortgaged Property, at any time and from time to time, to inspect the same, to perform or observe any covenant, conditions,
or terms which Mortgagor shall fail to perform, meet or comply with, or for any other purpose in connection with the protection
or preservation of Mortgagee’s security, without thereby becoming liable to Mortgagor or any person in possession under Mortgagor.
Mortgagee is under no obligation to exercise the rights permitted by this Section. If any such inspection is made during construction
of the Mortgaged Property or thereafter, said inspection shall be strictly for the benefit of Mortgagee. Mortgagor hereby assumes
all inspection responsibilities with respect to the construction, if any, of the Mortgaged Property.

 

11.     Prior
Permitted Encumbrances. Mortgagor shall keep current and free from default all Prior Permitted Encumbrances. 

 

12.     Uniform Commercial
Code Security Interest. This Mortgage shall constitute a security agreement pursuant to the Uniform Commercial Code covering
any of the items or types of property included as part of the Mortgaged Property that may be subject to a security interest pursuant
to the Uniform Commercial Code, and Mortgagor hereby grants Mortgagee a security interest in such items or types of property. This
Mortgage or a reproduction hereof, is sufficient as a financing statement and as a financing statement, it covers goods which are
or are to become fixtures on the Land. The Mortgagor hereby authorizes the Mortgagee at any time and from time to time to file
any initial financing statements, amendments thereto and continuation statements with or without the signature of the Mortgagor
as authorized by applicable law, as applicable to all or part of the Mortgaged Property and/or the Mortgaged Property. Mortgagor
shall pay all costs of filing such instruments. For purposes of such filings, the Mortgagor agrees to furnish any information requested
by the Mortgagee promptly upon request by the Mortgagee. The Mortgagor also ratifies its authorization for the Mortgagee to have
filed any like initial financing statements, amendments thereto and continuation statements, if filed prior to the date of this
security instrument. The Mortgagor hereby irrevocably constitutes and appoints the Mortgagee and any officer or agent of the Mortgagee,
with full power of substitution, as its true and lawful

 

    	-8-

    	 

    

 

attorneys-in-fact with
full irrevocable power and authority in the place and stead of the Mortgagor or in the Mortgagor’s own name to execute in the
Mortgagor’s name any documents and otherwise to carry out the purposes of this Section 12, to the extent that the Mortgagor’s
authorization above is not sufficient. To the extent not permitted by law, the Mortgagor hereby ratifies all acts said attorneys-in-fact
have lawfully done in the past or shall lawfully do or cause to be done in the future by virtue hereof. This power of attorney
is coupled with an interest and shall be irrevocable. 

 

13.     Condemnation.
If all or any part of the Mortgaged Property is damaged, taken, or acquired, either temporarily or permanently, in any condemnation
proceeding, or by exercise of the right of eminent domain, or by reason of sale under threat thereof, or in anticipation of the
exercise of the right of condemnation or other eminent domain proceedings, the amount of any award or other payment for such taking,
acquisition or damages made in consideration thereof, to the extent of the full amount of the remaining unpaid Indebtedness secured
by this Mortgage, is hereby assigned to Mortgagee, who is empowered to collect and receive the same and to give proper receipts
therefor in the name of Mortgagor and the same shall be paid forthwith to Mortgagee. Mortgagee at its option, may release any
such award or monies so received or apply same in whole or in part, after the payment of all of its expenses, including costs
and attorneys’ fees, on account of the last maturing installments of the Indebtedness, irrespective of whether such installments
are then due and payable. Mortgagor shall give written notice to Mortgagee immediately upon its receipt of notice of the institution
of any condemnation proceeding or other eminent domain proceedings or negotiations with respect thereto. 

 

14.     Subrogation.
If Mortgagee pays any prior lien from the proceeds of the loan secured by this Mortgage, it shall be subrogated to the rights
of the holder of such prior lien as fully as if such lien had been assigned to Mortgagee. 

 

15.     Protection of
Mortgagee’s Security. Subject to the rights of Mortgagor under paragraph 8 hereof, if Mortgagor fails to perform any of the
covenants and agreements contained in this Mortgage or if any action or proceeding is commenced which affects the Mortgaged Property
or the interest of Mortgagee therein, or the title thereto, then Mortgagee, at Mortgagee’s option, may perform such covenants and
agreements, defend against and/or investigate such action or proceeding, and take such other action as Mortgagee deems necessary
to protect Mortgagee’s interest. Mortgagee shall be the sole judge of the legality, validity and priority of any claim, lien, encumbrance,
tax, assessment, charge and premium paid by it and of the amount necessary to be paid in satisfaction thereof. Mortgagee is hereby
given the irrevocable power of attorney (which power is coupled with an interest and is irrevocable) to enter upon the Mortgaged
Property as Mortgagor’s agent in Mortgagor’s name to perform any and all covenants and agreements to be performed by Mortgagor
as herein provided. Any amounts or expenses disbursed or incurred by Mortgagee pursuant to this paragraph 15 with interest thereon,
shall become additional Indebtedness of Mortgagor secured by this Mortgage. Unless Mortgagor and Mortgagee agree in writing to
other terms of repayment, such amounts shall be immediately due and payable, and shall bear interest from the date of disbursement
at the annual rate stated in the Note which the Mortgage secures, unless collection from Mortgagor of interest at such rate

 

    	-9-

    	 

    

 

would
be contrary to applicable law, in which event such amounts shall bear interest at the highest rate which may be collected from
Mortgagor under applicable law. Mortgagee shall, at its option, be subrogated to the lien of any mortgage or other lien discharged
in whole or in part by Mortgagee under the provisions hereof, and any such subrogation rights shall be additional and cumulative
security for this Mortgage. Nothing contained in this paragraph 15 shall require Mortgagee to incur any expense or do any act hereunder
and Mortgagee shall not be liable to Mortgagor for any damages or claims arising out of action taken by Mortgagee pursuant to this
paragraph 15.

  

16.     No
Secondary Financing. Mortgagor shall not create or permit to be created or to remain, with the exception of the Prior Permitted
Encumbrances, any subordinate lien on the Mortgaged Property or any part thereof to secure any Indebtedness for borrowed money,
without obtaining the prior written consent of Mortgagee. 

 

17.     Change
in Tax Laws. Mortgagor will pay all taxes, assessments and other similar charges, other than Mortgagee’s income tax, which
may be assessed upon the Mortgaged Property, or upon Mortgagee’s interest therein, or upon this Mortgage or the monies secured
hereby without regard to any law heretofore enacted or hereafter to be enacted, imposing payment of the whole or any part thereof
upon Mortgagee. Upon violation of this undertaking or the passage of a law imposing payment of the whole or any portion of any
of the taxes aforesaid upon Mortgagee, or upon the rendering by any court of competent Jurisdiction of a decision that the undertaking
by Mortgagor as herein provided to pay taxes, assessments or other similar charges is legally inoperative, then and in any such
event the Indebtedness, without any deduction, shall at the option of Mortgagee become immediately due and payable, notwithstanding
anything contained in this Mortgage or any law hereafter enacted. 

 

18.     Miscellaneous
Rights of Mortgagee. Mortgagee may at any time and from time to time, without notice, release any person liable for payment
of any of the Indebtedness, extend the time or alter the terms of payment of any of the Indebtedness, accept additional security
of any kind, release any property securing the Indebtedness, consent to the making of any plat or map of the Land or the creation
of any easement thereon or any covenants restricting use or occupancy thereof, or alter or amend the terms of this Mortgage in
any way. No such release, modification, addition, or change shall affect the liability of any person other than the person so released
for payment of the Indebtedness, nor affect the priority and lien priority status of this Mortgage upon any property not so released.

  

19.     Costs
of Administration. If Mortgagor shall request any consent, agreement, modification, release or information from Mortgagee
concerning the Mortgaged Property, the Note, or any other agreement securing the Indebtedness, Mortgagor shall pay to Mortgagee
on demand a reasonable fee for considering the request along with any expenses such as appraisal fees, attorneys’ fees, or credit
report charges, whether or not the request is granted by Mortgagee. Such amounts shall become additional Indebtedness of Mortgagor
secured by this Mortgage and

 

    	-10-

    	 

    

 

shall bear interest from the date incurred or disbursed at the rate applicable to the principal provided
in the Note. 

 

20.     Event
of Default Defined. Each of the following occurrences shall constitute an Event of Default hereunder (hereinafter called “Event
of Default”): 

 

a.          Mortgagor
shall fail to duly and punctually pay any installment of interest or of principal and interest payable under the Note, or any
other payment of money to be made under the Note, or any other default or event of default occurs under the terms of the Note.

 

b.          Mortgagor
shall default in the performance of or breach of the agreement contained in paragraph 16 hereof.

 

c.          Mortgagor
shall fail to duly perform or observe any of the covenants or agreements contained in this Mortgage other than covenants, agreements
or events of default as defined in this paragraph 21 herein, after 30 days written notice to Mortgagor.

 

d.          Mortgagor

or nonaction.

 

i.          If
Mortgagor is dissolved or fails to be in good standing under the laws of the State of Delaware, after reasonable notice and opportunity

Immediately upon becoming aware of the
existence of any condition or event which constitutes, or which after notice or lapse of time, or both would constitute, an Event

Mortgagor has taken, is taking or proposes to take with respect thereto. 

 

21.     Remedies.
Upon the occurrence of any Event of Default or at any time thereafter until such Event of Default is cured to the written satisfaction
of Mortgagee, Mortgagee may, at its option, exercise one or more of the following rights and remedies (and any other rights and
remedies available to it): 

 

a.          Mortgagee
may, by written notice to Mortgagor declare immediately due and payable all unmatured Indebtedness secured by this Mortgage, and
the same shall thereupon be immediately due and payable, without further notice or demand. 

 

b.          Mortgagee
shall have and may exercise with respect to all personal property and fixtures which are part of the Mortgaged Property, and with
respect to the Revenues and Income, all the rights and remedies accorded upon default to a secured party under the Uniform Commercial
Code, as in effect in the State of Minnesota. If notice to Mortgagor of intended disposition of such property is required by law
in a particular instance, such notice shall be deemed commercially reasonable if given to Mortgagor (in the manner specified in
paragraph 28) at least 10 calendar days prior to the date of intended disposition. Mortgagor shall pay on demand all costs and
expenses incurred by Mortgagee in exercising such rights and remedies, including without limitation, reasonable attorneys’ fees
and legal expenses. 

 

c.          Mortgagee
may (and is hereby authorized and empowered to) foreclose this Mortgage by action or advertisement, pursuant to the statutes of
the State of Minnesota in such case made and provided, power being expressly granted to sell the Mortgaged Property at public
auction and convey the same to the purchaser in fee simple, and, out of the proceeds arising from such sale, to pay all Indebtedness
secured hereby with interest, and all legal costs and charges of such foreclosure and the maximum attorneys’ fees permitted by
law, which costs, charges and fees Mortgagor agrees to pay.

 

    	-12-

    	 

    

 

d.          Mortgagor
hereby waives all right of homestead exemption in the Mortgaged Property. 

 

22.     Waiver
of Rights Regarding Remedies. Mortgagor understands and agrees that if an “Event of Default” (as defined in paragraph
21) shall occur, Mortgagee has the right, among others, to foreclose this Mortgage by advertisement pursuant to Minnesota Statutes,
Chapter 580 as now in effect or as it may be hereafter amended, or pursuant to any similar or replacement statute hereafter enacted.
That under said Chapter 580 as now in effect, if Mortgagee elects to foreclose by advertisement, it may cause the Mortgaged Property,
or any part thereof, to be sold at public auction; that notice of such sale must be published for six weeks and served upon all
persons in possession of the Mortgaged Property at least four weeks before the sale; that after sale, Mortgagor will have six
or twelve months or such other period as may then be provided by law, if any, to redeem the Mortgaged Property so sold, depending
upon circumstances outlined in Minnesota Statutes, Section 580.23, by paying the sale price, any taxes, assessments and insurance
premiums paid by the purchaser at such sale and other sums permitted by law, together with interest thereon from the date of sale
at the highest rate permitted by law. 

 

Mortgagor further
understands that in the event of such default, Mortgagee may take possession of any personal property covered by this Mortgage
and dispose of the same by sale or otherwise in one or more parcels; provided that at least 10 days’ prior notice of such disposition
that must be given to Mortgagor, all as provided for by the Minnesota Uniform Commercial Code, as now in effect or as hereafter
amended, or by any similar or replacement statute hereafter enacted.

 

Mortgagor further
understands that under the Constitution of the United States and the State of Minnesota, Mortgagor may have the right to notice
and hearing before the Mortgaged Property may be sold and that the procedure for foreclosure by advertisement described above
does not insure that notice will be given to Mortgagor, and neither said procedure for foreclosure by advertisement nor the Uniform
Commercial Code requires any such hearing or other Judicial proceeding. 

 

MORTGAGOR HEREBY RELINQUISHES,
WAIVES AND GIVES UP MORTGAGOR’S CONSTITUTIONAL RIGHTS, IF ANY, TO NOTICE AND HEARING BEFORE SALE OF THE MORTGAGED PROPERTY AND
EXPRESSLY CONSENTS AND AGREES THAT THE MORTGAGED PROPERTY MAY BE FORECLOSED BY ADVERTISEMENT AND THAT PERSONAL PROPERTY COVERED
BY THIS MORTGAGE AND SECURITY AGREEMENT MAY BE DISPOSED OF PURSUANT TO THE UNIFORM COMMERCIAL CODE, ALL AS DESCRIBED ABOVE. 

 

23.     Waiver of Marshalling.
Mortgagor, any party who consents to this Mortgage and any party who now or hereafter acquires a lien on the Mortgaged Property
and who has actual or constructive notice of this Mortgage hereby waives any and all right to require the marshalling of

 

    	-13-

    	 

    

 

assets
in connection with the exercise of any of the remedies permitted by applicable law or provided herein.

 

24.     Forbearance
by Mortgagee Not a Waiver. Any delay by Mortgagee in exercising any right or remedy hereunder, or otherwise afforded by law
or equity shall not be a waiver of or preclude the exercise of such right or remedy or any other right or remedy hereunder or
at law or equity. The failure of Mortgagee to exercise any option to accelerate maturity of the Indebtedness secured by the Mortgage,
the forbearance by Mortgagee before or after the exercise of such option, or the withdrawal or abandonment of proceedings provided
for by this Mortgage shall not be a waiver of the right to exercise such option or to accelerate the maturity of such Indebtedness
by reason of any past, present or future event which would permit acceleration under paragraph 22 hereof. The procurement of insurance
or the payment of taxes or other liens or charges by Mortgagee shall not be a waiver of Mortgagee’s right to accelerate the maturity
of the Indebtedness hereby secured. 

 

25.     Mortgagee’s
Remedies Cumulative. All remedies of Mortgagee are distinct and cumulative to any other right or remedy under this Mortgage
or afforded by law or equity, and may be exercised concurrently or independently and as often as the occasion therefor arises.

 

26.     Successors and
Assigns Bound, Captions. The covenants and agreements herein contained shall bind, and the rights hereunder shall inure to,
the respective heirs, personal representatives, successors and assigns of Mortgagee and Mortgagor and shall bind persons who become
bound as a debtor to this Mortgage. The captions and headings of the paragraphs of this Mortgage are for convenience only and are

before and after commencement of any action or procedure to foreclose the Mortgage, after the foreclosure sale of the Mortgaged
Property in connection with the foreclosure of the Mortgage, and until expiration of the period of redemption from any such foreclosure
sale, whether or not any deficiency from the unpaid balance of the Obligations Secured Hereby exists after such foreclosure sale.

  

6.          No
Liability for Lender. Lender shall not be obligated to perform or discharge, nor does it hereby undertake to perform or discharge
any obligation, duty or liability under any Lease, nor shall this Assignment operate to place responsibility for the control,
care, management or repair of the Mortgaged Property upon Lender, nor for the carrying out of any of the terms and conditions
of any Lease; nor shall it operate to make Lender responsible or liable for any waste committed on the Mortgaged Property by a
Lessee or any other party, or for any dangerous or defective condition of the Mortgaged Property or for any negligence in the
management, upkeep, repair or control of the Mortgaged Property resulting in loss or injury or death to any Lessee, licensee,
employee or stranger.

 

7.          Assignor
to Hold Lender Harmless. Assignor shall and does hereby agree to indemnify and to hold Lender harmless of and from any and
all liability, loss or damage which it may or might incur under any Lease or under or by reason of this Assignment and of and
from any and all claims and demands whatsoever which may be asserted against it by reason of any alleged obligations or undertakings
on its part to perform or discharge any of the terms, covenants or agreements contained in any Lease. Should Lender incur such
liability, loss or damage under any Lease or under or by reason of this Assignment, or in the defense of any such claims or demands,
the amount thereof, including costs, expenses, and reasonable attorneys’ fees, shall be secured hereby and Assignor shall reimburse
Lender therefor immediately upon demand, and upon the failure of Assignor so to do Lender may declare all Obligations Secured
Hereby immediately due and payable.

 

8.          Specific
Assignment of Subsequent Lease. Assignor covenants, and agrees promptly upon request of Assignee, to transfer and assign to
Lender any specific Lease of all or any part of the Mortgaged Property upon the same terms and conditions as are herein contained. 

 

9.          Remedies
not Exclusive. This Assignment shall in no way operate to prevent Lender from pursuing any remedy which it now has or hereafter
may have under the terms or conditions of the Note or the Mortgage, or any other instrument securing the same, or by law, but
shall be deemed an additional remedy and shall be cumulative with the remedies granted therein.

10.          Authorization
to Lessees. Lessees are hereby irrevocably authorized and directed to recognize the claims of Lender, or its assigns, hereunder
without investigating the reason for any action taken by Lender, or the validity or the amount of indebtedness owing to Lender,
or the existence of any default in the Note, the Mortgage, or under or by reason of this Assignment, or the application of the
Rents to be made by Lender. Assignor hereby irrevocably directs and authorizes Lessees to pay to Lender all sums due under any
Lease and consents and directs that said sums shall be paid to Lender without the necessity for a Judicial determination that
a default has occurred hereunder or under the Note, or the Mortgage, or that Lender is entitled to exercise its rights hereunder,
and to the extent such sums are paid to Lender, Assignor agrees that Lessees shall have no further liability to Assignor for the
same. The sole signature of Lender shall be sufficient for the exercise of any rights under this Assignment and the sole receipt
of Lender for any sums received shall be a full discharge and release therefor to Lessees.

 

11.          Notices.
