INDEBTEDNESS AND (B) PERFORMANCE OF ANY AND ALL OBLIGATIONS UNDER THE NOTE,
THE RELATED DOCUMENTS, AND THIS MORTGAGE. THIS MORTGAGE, INCLUDING THE

DEFAULT UNDER THIS MORTGAGE. THIS MORTGAGE IS GIVEN AND ACCEPTED ON THE
FOLLOWING TERMS:

 

MORTGAGE
TERM AND LIEN. This Mortgage shall, notwithstanding the fact
that from time to time during the term hereof no Indebtedness may be due from
Grantor to Lender, constitute a continuing lien against the Property for the
amount stated in this document. If at any time the Indebtedness due Lender is
zero dollars ($0.00), Lender shall, within ten (10) days after receipt of
written demand for satisfaction of this Mortgage by Grantor, execute and record

Mortgage is five (5) years from the date of filing unless such term is
extended by the filing of an Addendum to this Mortgage. Any Addendum
to this Mortgage need be signed only by Lender. Upon the timely filing of such
an Addendum to this Mortgage, the effectiveness of this Mortgage shall be
continued for five (5) years after the date of filing. This Mortgage shall
lapse after the additional five (5) year period unless another Addendum to

MORTGAGE

this Mortgage is filed
continuing the effectiveness of this Mortgage prior to such lapse. Succeeding
Addendums to this Mortgage may be filed in the same manner to continue the
effectiveness of the lien of this Mortgage.

 

PAYMENT

Mortgage, Grantor shall pay to Lender all amounts secured by this Mortgage as
they become due and shall strictly perform all of Grantor’s obligations under
this Mortgage.

 

POSSESSION

possession and use of the Property shall be governed by the following
provisions:

 

Possession
and Use. Until the occurrence of an Event of Default, Grantor
may (1) remain in possession and control of the Property; (2) use, operate
or manage the Property; and (3) collect the Rents from the Property.

 

Duty to
Maintain. Grantor shall maintain the Property in tenantable
condition and promptly perform all repairs, replacements, and maintenance

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, defend, and hold harmless Lender against any and all claims, losses,

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 and defend, shall survive the payment of the
Indebtedness and the satisfaction and

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

Property are reasonably necessary to protect and preserve the Property.

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

MORTGAGE 

(Continued)

 

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.

authorize the appropriate governmental official to deliver to Lender at any
time a written statement of the taxes and assessments against the Property.

 

Notice

(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 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

 

5

 

MORTGAGE 

(Continued)

 

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.

 

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, 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 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
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 any title insurance policy, title report, or final
title opinion issued in favor of, and accepted by, Lender in connection with
this Mortgage, and (b) Grantor has the full right, power, and authority to
execute and deliver this Mortgage to Lender.

 

Defense
of Title. Subject to the exception in the paragraph above, Grantor
warrants and will

MORTGAGE 

(Continued)

 

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.

 

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.

 

IMPOSITION
OF TAXES, FEES AND CHARGES BY GOVERNMENTAL AUTHORITIES. The
following provisions relating to governmental taxes, fees and charges are a
part of this Mortgage:

 

Current
Taxes, Fees and Charges. Upon request by Lender, Grantor
shall execute such documents in addition to this Mortgage and take whatever
other action is requested by Lender to perfect and continue Lender’s lien on
the Real Property. Grantor shall reimburse Lender for all taxes, as described
below, together with all expenses incurred in recording, perfecting or
continuing this Mortgage, including without limitation all taxes, fees, documentary
stamps, and other charges for recording or registering this Mortgage.

Subsequent
Taxes. If any
tax to which this section applies is enacted 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 available remedies for an Event of
Default as provided below unless Grantor either (1) pays the tax before it
becomes delinquent, or (2) contests the tax as provided above in the Taxes
and Liens section and deposits with Lender cash or a sufficient corporate
surety bond or other security satisfactory to Lender.

 

SECURITY
AGREEMENT; FINANCING STATEMENTS. The following provisions
relating to this Mortgage as a security agreement are a part of this Mortgage:

Code as amended from time to time.

action is requested by Lender to perfect and continue Lender’s security
interest in the Rents and Personal Property. In addition to recording this
Mortgage in the real property records, Lender may, at any time and without
further authorization from Grantor, file executed counterparts, copies or

reimburse Lender for all expenses incurred in perfecting or continuing this
security interest. Upon default, Grantor shall not remove, sever or detach the
Personal Property from the Property. Upon default, Grantor shall assemble any

times and in such offices and places as Lender may deem appropriate, any and
all such mortgages, deeds of trust, security deeds, security agreements, financing
statements, continuation statements, instruments of further assurance, certificates,
and other documents as may, in the sole opinion of Lender, be necessary or
desirable in order to effectuate, complete, perfect, continue, or preserve
(1) Grantor’s obligations under the Note, this Mortgage, and the Related
Documents, and (2) the liens and security interests created by this
Mortgage as first and prior liens on the Property, whether now owned or
hereafter acquired by Grantor. Unless prohibited by law or Lender agrees to the
contrary in writing, Grantor shall reimburse Lender for all costs and expenses
incurred in connection with the matters referred to in this paragraph.

preceding

MORTGAGE 

(Continued)

 

paragraph, Lender may do

hereby irrevocably appoints Lender as Grantor’s attorney-in-fact for the
purpose of making, executing, delivering, filing, recording, and doing all
other things as may be necessary or desirable, in Lender’s sole opinion, to
accomplish the matters referred to in the preceding paragraph.

grace period provided therein, including without limitation any agreement

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

Right

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

Property, Lender shall have all the rights and remedies of a secured party
under the Uniform Commercial Code.

 

Collect
Rents. Grantor shall have the right, prior to default or
abandonment of the Property, to collect and retain the Rents as they become due

effective until the payment of all Indebtedness secured by this Mortgage, or in
the event of foreclosure, until the period of redemption expires. Regardless of
the extinguishment of the Indebtedness by a foreclosure sale, this benefit
shall continue for the benefit of the purchaser at the foreclosure sale.

 

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
Sale. If permitted by applicable law, Lender may foreclose
Grantor’s interest in

all or in any part of the
Personal Property or the Real Property by non-judicial sale.

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.

 

Redemption.
THE PARTIES AGREE THAT THE PROVISIONS OF THE 180-DAY REDEMPTION MORTGAGE ACT
GOVERN THIS MORTGAGE. THIS SHALL CONSTITUTE AND AUTHORIZE A POWER OF SALE UNDER
THE PROVISIONS OF SUCH ACT. Grantor agrees that, in the event of a foreclosure of this
Mortgage by action, the holder of the certificate of sale conducted as a result
of the foreclosure may apply to the appropriate court for a reduction of the
redemption period if Grantor has abandoned the Property. Grantor agrees that if,
after notice to the parties as the court may direct, the court finds that the
Property has been abandoned, then the redemption period may be reduced to a
period of not less than sixty (60) days from the date of recording of the
certificate of sale issued as a result of the foreclosure of this Mortgage.

 

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.

 

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

 

11

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.

Lender to any Grantor is deemed to be notice given to all Grantors.

not prejudice or constitute a waiver of Lender’s right otherwise to demand

Grantor, shall constitute a waiver of any of Lender’s rights or of any of

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.

in the Property at any time held by or for the benefit of Lender in any

to any limitations stated in this Mortgage on transfer of Grantor’s interest,

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

of this Mortgage or liability under the Indebtedness.

THIS ASSIGNMENT OF DEPOSIT ACCOUNT dated April 28, 2009,
is made and executed between TOWER TECH SYSTEMS INC (“Grantor”) and GREAT
WESTERN BANK (“Lender”).

 

ASSIGNMENT. For valuable consideration,
Grantor assigns and grants to Lender a security interest in the Collateral, including
without limitation the deposit accounts described below, to secure the
Indebtedness and agrees that Lender shall have the rights stated in this
Agreement with respect to the Collateral, in addition to all other rights which
Lender may have by law.

 

COLLATERAL DESCRIPTION. The word “Collateral” means
the following described deposit account (“Account”):

 

Savings Account Number 1347401 with
Lender

 

together
with (A) all interest, whether now accrued or hereafter accruing; (B) all
additional deposits hereafter made to the Account; (C) any and all
proceeds from the Account; and (D) all renewals, replacements and
substitutions for any of the foregoing.

 

CROSS-COLLATERALIZATION. In addition to the Note, this
Agreement secures all obligations, debts and liabilities, plus interest
thereon, of Grantor to Lender, or any one or more of them, as well as all
claims by Lender against Grantor or any one or more of them, whether now
existing or hereafter arising, whether related or unrelated to the purpose of
the Note, whether voluntary or otherwise, whether due or not due, direct or
indirect, determined or undetermined, absolute or contingent, liquidated or
unliquidated, whether Grantor may be liable individually or jointly with
others, whether obligated as guarantor, surety, accommodation party or
otherwise, and whether recovery upon such amounts may be or hereafter may
become barred by any statute of limitations, and whether the obligation to
repay such amounts may be or hereafter may become otherwise unenforceable.

 

RIGHT OF SETOFF. To the extent permitted by
applicable law, Lender reserves a right of setoff in all Grantor’s accounts
with Lender (whether checking, savings, or some other account). This includes
all accounts Grantor holds jointly with someone else and all accounts Grantor
may open in the future. However, this does not include any IRA or Keogh
accounts, or any trust accounts for which setoff would be prohibited by law. Grantor
authorizes Lender, to the extent permitted by applicable law, to charge or
setoff all sums owing on the Indebtedness against any and all such accounts.

 

GRANTOR’S REPRESENTATIONS AND WARRANTIES WITH RESPECT TO THE
COLLATERAL. With respect to the Collateral, Grantor represents
and promises to Lender that:

 

Ownership. Grantor is the lawful owner
of the Collateral free and clear of all loans, liens, encumbrances, and claims
except as disclosed to and accepted by Lender in writing.

 

Right to Grant Security Interest. Grantor has the
full right, power, and authority to enter into this Agreement and to assign the
Collateral to Lender.

 

No Prior Assignment. Grantor has not
previously granted a security interest in the Collateral to any other creditor.

 

No Further Transfer. Grantor shall
not sell, assign, encumber, or otherwise dispose of any of Grantor’s rights in
the Collateral except as provided in this Agreement.

 

No Defaults. There are no
defaults relating to the Collateral, and there are no offsets or counterclaims
to the same. Grantor will strictly and promptly do everything required of
Grantor under the terms, conditions, promises, and agreements contained in or
relating to the Collateral.

 

Proceeds. Any and all
replacement or renewal certificates, instruments, or other benefits or proceeds
related to the Collateral that are received by Grantor shall be held by Grantor
in trust for Lender and immediately shall be delivered by Grantor to Lender to
be held as part of the Collateral.

 

Validity; Binding Effect. This Agreement
is binding upon Grantor and Grantor’s successors and assigns and is legally
enforceable in accordance with its terms.

 

Financing Statements. Grantor
authorizes Lender to file a UCC financing statement, or alternatively, a copy
of this Agreement to perfect Lender’s security interest. At Lender’s request,
Grantor additionally agrees to sign all other documents that are necessary to
perfect, protect, and continue: Lender’s
security interest in the Property. This includes making sure Lender is shown as
the first and only security interest holder on the title covering the Property.
Grantor will pay all filing fees, title transfer fees, and other fees and costs
involved unless prohibited by law or unless Lender is required by law to pay
such fees and costs. Grantor irrevocably appoints Lender to execute documents
necessary to transfer title if there is a default. Lender may file a copy of
this Agreement as a financing statement. If Grantor changes Grantor’s name or
address, or the name or address of any person granting a security interest
under this Agreement changes, Grantor will promptly notify the Lender of such
change.

 

LENDER’S RIGHTS AND OBLIGATIONS WITH RESPECT TO THE
COLLATERAL. While this Agreement is in effect, Lender may retain
the rights to possession of the Collateral, together with any and all evidence
of the Collateral, such as certificates or passbooks. This Agreement will
remain in effect until (a) there no longer is any Indebtedness owing to
Lender; (b) all other obligations secured by this Agreement have been
fulfilled; and (c) Grantor, in writing, has requested from Lender a
release of this Agreement.

 

LENDER’S EXPENDITURES. If any action or proceeding
is commenced that would materially affect Lender’s interest in the Collateral
or if Grantor fails to comply with any provision of this Agreement or any
Related Documents, including but not limited to Grantor’s failure to discharge
or pay when due any amounts Grantor is required to discharge or pay under this
Agreement 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 Collateral
and paying all costs for insuring, maintaining and preserving the Collateral.
All such expenditures incurred or paid by Lender for such purposes will then
bear interest at the rate charged under the Note 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 Agreement 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.

 

LIMITATIONS ON OBLIGATIONS OF LENDER. Lender shall use
ordinary reasonable care in the physical preservation and custody of any
certificate or passbook for the Collateral but shall have no other obligation
to protect the Collateral or its value. In particular, but without limitation,
Lender shall have no responsibility (A) for the collection or protection
of any income on the Collateral; (B) for the preservation of rights
against issuers of the Collateral or against third persons; (C) for
ascertaining any maturities, conversions, exchanges, offers, tenders, or similar
matters relating to the Collateral; nor (D) for informing the Grantor
about any of the above, whether or not Lender has or is deemed to have
knowledge of such matters.

 

DEFAULT. Each of the following shall
constitute an Event of Default under this Agreement:

 

Payment Default. Grantor fails to
make any payment when due under the Indebtedness.

 

Other Defaults. Grantor fails to
comply with or to perform any other term, obligation, covenant or condition
contained in this Agreement or in any of the Related Documents or to comply
with or to perform any term, obligation, covenant or condition contained in any
other agreement between Lender and Grantor.

 

False Statements. Any warranty,
representation or statement made or furnished to Lender by Grantor or on
Grantor’s behalf under this Agreement 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 Agreement 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.

 

Insolvency. The dissolution
or termination of Grantor’s existence as a going business, the insolvency of
Grantor, the appointment of a receiver for any part of Grantor’s property, any
assignment for the benefit of creditors, any type of creditor workout, or the

against Grantor.

 

Creditor or Forfeiture Proceedings. Commencement of
foreclosure or forfeiture proceedings, whether by judicial proceeding,
self-help, repossession or any other method, by any creditor of Grantor or by
any governmental agency against any collateral securing the Indebtedness. This
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

 

 

ASSIGNMENT OF DEPOSIT ACCOUNT

(Continued)

 

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.

 

Events Affecting Guarantor. Any of the
preceding events occurs with respect to any Guarantor of any of the
Indebtedness or Guarantor dies or becomes incompetent or revokes or disputes
the validity of, or liability under, any Guaranty of the Indebtedness.

 

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.

 

Cure Provisions. 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 Agreement 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 sole
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, or at any time thereafter, Lender may
exercise any one or more of the following rights and remedies, in addition to
any rights or remedies that may be available at law, in equity, or otherwise:

declare all Indebtedness of Grantor to Lender immediately due and payable,
without notice of any kind to Grantor.

directly all funds in the Account and apply them to the Indebtedness. If the
Account is subject to an early withdrawal penalty, that penalty shall be
deducted from the Account before its application to the Indebtedness, whether
the Account is with Lender or some other institution. Any excess funds remaining
after application of the Account proceeds to the Indebtedness will  be paid to Grantor as the interests of
Grantor may appear. Grantor agrees, to the extent permitted by law, to pay any
deficiency after application of the proceeds of the Account to the
Indebtedness. Lender also shall have all the rights of a secured party under
the South Dakota Uniform Commercial Code, even if the Account is not otherwise
subject to such Code concerning security interests, and the parties to this
Agreement agree that the provisions of the Code giving rights to a secured
party shall nonetheless be a part of this Agreement.

 

Transfer Title. Lender may
effect transfer of title upon sale of all or part of the Collateral. For this
purpose, Grantor irrevocably appoints Lender as Grantor’s attorney-in-fact to
execute endorsements, assignments and instruments in the name of Grantor and
each of them (if more than one) as shall be necessary or reasonable.

 

Other Rights and Remedies. Lender shall
have and may exercise any or all of the rights and remedies of a secured
creditor under the provisions of the South Dakota Uniform Commercial Code, at
law, in equity, or otherwise.

 

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.

 

Election of Remedies. Except as may be
prohibited by applicable law, all of Lender’s rights and remedies, whether evidenced
by this Agreement or by any other writing, shall be cumulative and may be
exercised singularly or concurrently. 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
Agreement, after Grantor’s failure to perform, shall not affect Lender’s right
to declare a default and exercise its remedies.

 

Cumulative Remedies. All of Lender’s
rights and remedies, whether evidenced by this Agreement or by any other
writing, shall be cumulative and may be exercised singularly or concurrently. 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 Agreement, after Grantor’s failure to perform, shall not
affect Lender’s right to declare a default and to exercise its remedies.

 

MISCELLANEOUS PROVISIONS. The following miscellaneous
provisions are a part of this Agreement:

 

Amendments. This Agreement,
together with any Related Documents, constitutes the entire understanding and
agreement of the parties as to the matters set forth in this Agreement. No
alteration of or amendment to this Agreement shall be effective unless given in
writing and signed by the party or parties sought to be charged or bound by the
alteration or amendment.

 

Attorneys’
Fees; Expenses. Grantor agrees to pay upon demand all of Lender’s
costs and expenses, including Lender’s attorneys’ fees and Lender’s legal
expenses, incurred in connection with the enforcement of this Agreement. Lender
may hire or pay someone else to help enforce this Agreement, and Grantor shall
pay the costs and expenses of such enforcement. Costs and expenses include Lender’s
attorneys’ fees and legal expenses whether or not there is a lawsuit, including
attorneys’ fees and legal expenses for bankruptcy proceedings (including
efforts to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgment collection services. Grantor also shall pay all court
costs and such additional fees as may be directed by the court.

 

Caption Headings. Caption headings
in this Agreement are for convenience purposes only and are not to be used to
interpret or define the provisions of this Agreement.

 

Governing Law. This Agreement will
be governed by federal law applicable to Lender and, to the extent not
preempted by federal law, the laws of the State of South Dakota without regard
to its conflicts of law provisions. This Agreement has been accepted by Lender
in the State of South Dakota.

 

Choice of Venue. If there is a
lawsuit, Grantor agrees upon Lender’s request to submit to the jurisdiction of
the courts of Minnehaha County, State of South Dakota.

 

No Waiver by Lender. Lender shall not
be deemed to have waived any rights under this Agreement 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 Lender
of a provision of this Agreement shall not prejudice or constitute a waiver of
Lender’s right otherwise to demand strict compliance with that provision or any
other provision of this Agreement. No prior waiver by Lender, nor any course of
dealing between Lender and Grantor, shall constitute a waiver of any of Lender’s
rights or of any of Grantor’s obligations as to any future transactions. Whenever
the consent of Lender is required under this Agreement, the granting of such
consent by Lender in any instance shall not constitute continuing consent to
subsequent instances where such consent is required and in all cases such
consent may be granted or withheld in the sole discretion of Lender.

 

Notices. Any notice
required to be given under this Agreement shall be given in writing, and shall
be effective when actually delivered, when actually received by telefacsimile
(unless otherwise required by law), when deposited with a nationally recognized
overnight courier, or, if mailed, when deposited in the United States mail, as
first class, certified or registered mail postage prepaid, directed to the
addresses shown near the beginning of this Agreement. Any party may change its
address for notices under this Agreement 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.

 

Power of Attorney. Grantor hereby
appoints Lender as its true and lawful attorney-in-fact, irrevocably, with full
power of substitution to do the following: (1) to demand, collect,
receive, receipt for, sue and recover all sums of money or other property which
may now or hereafter become due, owing or payable from the Collateral; (2) to
execute, sign and endorse any and all claims, instruments, receipts, checks,
drafts or warrants issued in payment for the Collateral; (3) to settle or
compromise any and all claims arising under the Collateral, and in the place
and stead of Grantor, to execute and deliver its release and settlement for the
claim; and (4) to file any claim or claims or to take any action or
institute or take part in any proceedings, either in its own name or in the
name of Grantor, or otherwise, which in the discretion of Lender may seem to be
necessary or advisable. This power is given as security for the Indebtedness,
and the authority hereby conferred is and shall be irrevocable and shall remain
in full force and effect until renounced by Lender.

 

Severability. If a court of
competent jurisdiction finds any provision of this Agreement 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 Agreement. Unless
otherwise required by law, the illegality, invalidity, or unenforceability of any
provision of this Agreement shall not affect the legality, validity or
enforceability of any other provision of this Agreement.

 

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

 

Survival of Representations and
Warranties. All representations, warranties, and agreements made
by Grantor in this Agreement shall survive the execution and delivery of this
Agreement, 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.

 

Time is of the Essence. Time is of the
essence in the performance of this Agreement.
