Borrower hereby requests, and Lender hereby agrees to restructure the indebtedness represented by the Secured Demand Notes by having $11,522,000.000 representing the aggregate principal amount of the Secured Demand Notes converted into a Revolving Loan. Each other Revolving Loan under this Section 2.01(a) shall be for an aggregate principal amount of at least $500,000 or any larger multiple of $25,000. The aggregate principal amount of Revolving Loans which Lender may have outstanding under this Agreement as of any date shall not exceed the amount of Lender’s Revolving Credit Commitment as of such date. In no event shall the aggregate principal amount of all Revolving Loans outstanding as of any date exceed the amount of Lender’s Revolving Credit Commitment as of such date. Within the foregoing limits and in Lender’s sole and absolute discretion, Borrower may borrow under this Section 2.01(a), prepay under Section 2.04(f) and reborrow at any time during the Revolving Credit Period under this Section 2.01(a), subject to the limitations and procedures contained in this Section 2.01.

request from time to time.

You may later cancel any insurance purchased by us, but only after providing us with evidence that you have obtained insurance as required by our agreement. If we purchase insurance for the collateral, you will be responsible for the costs of that insurance, including interest and any other charges we may impose in connection with the placement of the insurance, until the effective date of the cancellation or expiration of the insurance.

SECTION 8 — GENERAL

8.01 No Waiver. No failure or delay by Lender or the holder of the Notes in exercising any right, remedy, power or privilege hereunder or under any other Transaction Document shall operate as a waiver thereof; nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The remedies provided herein and in the other Transaction Documents are cumulative and not

exclusive of any remedies provided by law. Nothing herein contained shall in any way affect the right of Lender to exercise any statutory or common law right of banker’s lien or set-off.

8.02 Right of Set-Off. Upon the occurrence and during the continuance of any Event of Default under this Agreement, Lender is hereby authorized at any time and from time to time to set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and any and all other indebtedness at any time owing by Lender to or for the credit or the account of Borrower, any Subsidiary Holding Company or any Subsidiary Bank against any and all of the Obligations irrespective of whether or not Lender shall have made any demand hereunder or thereunder. Lender agrees promptly to notify Borrower after any such set-off and application made by Lender, provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of Lender under this Section 8.02 are in addition to any other rights and remedies (including, without limitation, other rights of set-off) which Lender may have. Nothing contained in this Agreement or any other Transaction Document shall impair the right of Lender to exercise any right of set-off or counterclaim it may have against Borrower, any Subsidiary Holding Company or any Subsidiary Bank and to apply the amount subject to such exercise to the payment of indebtedness of Borrower unrelated to this Agreement or the other Transaction Documents.

8.03 Cost and Expenses.

Borrower hereby agrees to indemnify Lender and hold Lender harmless from and against any and all losses, liabilities, damages, injuries, costs, expenses and claims of any and every kind whatsoever (including, without limitation, court costs and Attorneys’ Fees) which at any time or from time to time may be paid, incurred or suffered by, or asserted against, Lender for, with respect to or as a direct or indirect result of the violation by Borrower, any Subsidiary Holding Company or any Subsidiary Bank of any Federal, state or local laws, rules, regulations or ordinances relating to the environment, health or safety, including laws, rules, regulations or ordinances relating to solid waste and/or hazardous waste treatment, storage, disposal, generation and transportation, air, water and/or noise pollution, soil or ground or water contamination, the handling, storage or release into the environment of hazardous materials or hazardous substances, and the transportation of hazardous materials (“Environmental Laws”); or with respect to, or as a direct or indirect result of the presence on or under, or the escape, seepage, leakage, spillage, discharge, emission or release from, properties utilized by Borrower, any Subsidiary Holding Company or any Subsidiary Bank, in the conduct of their respective businesses into or upon any land, the atmosphere or any watercourse, body of

water or wetland, of any hazardous material or substances (including, without limitation, any losses, liabilities, damages, injuries, costs, expenses or claims asserted or arising under the Environmental Laws); and the provisions of and undertakings and indemnification set out in this Section 8.04 shall survive the satisfaction and payment of the Obligations and termination of this Agreement.

8.05 General Indemnity. In addition to the payment of expenses pursuant to Section 8.03, whether or not the transactions contemplated hereby shall be consummated, Borrower hereby agrees to indemnify, pay and hold Lender and any holder of any of the Notes, and the officers, directors, employees, agents and affiliates of Lender and such holder(s) (collectively called the “Indemnitees”) harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and disbursements of any kind or nature whatsoever (including, without limitation, the reasonable fees and disbursements of counsel for such indemnities in connection with any investigative, administrative or judicial proceeding commenced or threatened, whether or not such Indemnitees shall be designated a party thereto), that may be imposed on, incurred by or asserted against the Indemnitees, in any manner relating to or arising out of this Agreement, the other Transaction Documents, or other agreements executed and delivered by Borrower, any Subsidiary Holding Company, any Subsidiary Bank or any other Obligor in connection herewith, the statements contained in any commitment letters delivered by Lender, Lender’s agreement to make the Loan hereunder or the use or intended use of the proceeds of the Loan hereunder (the “Indemnified Liabilities”); that Borrower shall have no obligation to the Indemnitees with respect to Indemnified Liabilities arising from the negligence or willful misconduct of the Indemnitees as determined by a court of competent jurisdiction. To the extent that the undertaking to indemnify, pay and hold harmless set forth in the preceding sentence may be unenforceable because it is violative of any law or public policy, Borrower shall contribute the maximum portion that it is permitted to pay and satisfy under applicable law to the payment and satisfaction of all Indemnified Liabilities incurred by the Indemnitees or any of them. The provisions of the undertakings and indemnification set out in this Section 8.05 shall survive satisfaction and payment of the Obligations and termination of this Agreement.

8.06 Authority to Act. Lender shall be entitled to act on any notices and instructions (telephonic or written) reasonably believed by Lender to have been delivered by any Person authorized to act on behalf of Borrower pursuant hereto, regardless of whether such notice or instruction was in fact delivered by a Person authorized to act on behalf of Borrower, and Borrower hereby agrees to indemnify Lender and hold Lender harmless from and against any and all losses and expenses, if any, ensuing from any such action.

Debtor acknowledges and agrees that it shall be reasonable for Secured Party to sell the Collateral on credit for present or future delivery without any assumption of any credit risk. In case of a public sale, notice published by Secured Party for ten (10) days in a newspaper of general circulation in the City or County where the sale is to be held shall be sufficient.

If any deficiency arises upon any such sale or sales Debtor agrees to pay the amount of such deficiency promptly upon demand with interest. Notwithstanding that Secured Party may continue to hold the Collateral and regardless of the value thereof, Debtor shall be and remain liable for the payment in full of the principal of and interest on any balance of the Liabilities and expenses at any time unpaid.

SECTION 15 — Secured Party shall have no duties or obligations with respect to the Collateral except that while the Collateral is in Secured Party’s possession, Secured Party’s obligation with respect to the same shall be limited to using reasonable care to preserve the physical condition of the same.

SECTION 16 — At any time, whether prior to or after the occurrence of an Event of Default under this Agreement, Secured Party may, at its option, but shall not be obligated to, surrender or deliver, without further liability on the part of Secured Party to account therefor, all or any part of the Collateral to or upon the written order of Debtor, permit substitutions therefor or additions thereto, and accept the receipt of Debtor for any Collateral, or proceeds thereof, which receipt shall be a full and complete discharge of Secured Party with respect to the Collateral so delivered and proceeds so paid.

THIS GUARANTY AGREEMENT (“Guaranty”) is made as of , 2009 by and between (“Guarantor”), and Great River Bancshares, Inc., a Nevada corporation (together with its successors and assigns, “Lender”).

RECITALS

The following recitals of fact are a material part of this Agreement:

SECTION 26 — Mercantile Bancorp, Inc., a Delaware corporation (“Borrower”), and U.S. Bank National Association, a national banking association (“US Bank”), previously entered into that certain Third Amended and Restated Term Loan Agreement, dated as of November 10, 2006, as subsequently amended from time to time (the “Original Loan Agreement”), and Borrower previously executed a Revolving Credit Note, dated as of November 10, 2006, in the principal amount of $15,000,000 in favor of US Bank, a Term Loan Promissory Note, dated as of November 10, 2006, in the principal amount of $15,000,000 in favor of US Bank, a Term Loan B Promissory Note, dated as of September 7, 2007, in the principal amount of $5,000,000, in favor of US Bank, and a Term Loan C Promissory Note, dated as of September 7, 2007, in the principal amount of $5,000,000, in favor of US Bank (collectively, the “US Bank Notes”).

SECTION 27 — Pursuant to an Assignment Agreement entered into among Borrower, US Bank and Lender, Lender has acquired and assumed from US Bank all of US Bank’s right, title and interest in and to the US Bank Notes and all of US Bank’s rights and obligations under the Original Loan Agreement and all documents and agreements related thereto.

SECTION 28 — On December 31, 2008, Lender made an additional loan to Borrower, and Borrower executed a Secured Demand Promissory Note, dated December 31, 2008, in the principal amount of $7,552,000 in favor of Lender (the “First Secured Demand Note”).

SECTION 29 — On February 5, 2009, Lender made an additional loan to Borrower, and Borrower executed a $4,000,000 Secured Demand Note, dated February 5, 2009, in the principal amount of $4,000,000 in favor of Lender (the “Second Secured Demand Note,” and together with the First Secured Demand Note, the “Secured Demand Notes”).

SECTION 30 — In connection with the acquisition and assumption of the US Bank Notes and US Bank’s rights and obligations under the Original Loan Agreement, Lender has agreed to enter into a Fourth Amended and Restated Loan Agreement (the “Loan Agreement”) with Borrower, which Loan Agreement restructures the Original Loan Agreement and the Secured Demand Notes. Capitalized terms used in this Guaranty but not otherwise defined herein shall have the meanings ascribed to them in the Loan Agreement.

SECTION 31 — In connection with the execution of the Loan Agreement, Lender has agreed to cancel the US Bank Notes and the Secured Demand Notes and re-issue a Revolving Note in the principal amount of $15,000,000, a Term Loan A Promissory Note in the principal

amount of $15,109,112.50, a Term Loan B Promissory Note in the principal amount of $5,036,609.72, and a Term Loan C Promissory Note in the principal amount of $2,014,978.34 (collectively, the “Lender Notes”).

SECTION 32 — Guarantor’s execution and delivery of this Guaranty is an important part of the consideration for Lender’s restructuring of the Original Loan Agreement and the Secured Demand Notes and the issuance of the Lender Notes, and Lender is not willing to take such actions unless this Guaranty is executed and delivered.

AGREEMENT

NOW, THEREFORE, to induce Lender to enter into the Loan Agreement, and in recognition that Lender would not enter into the Loan Agreement but for Guarantor’s promises and agreements hereunder, and for other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged by the parties, Guarantor hereby agrees as follows:

32.01 GUARANTY.

(a) Guarantor hereby unconditionally and irrevocably guarantees, as primary obligor and not merely as a surety, (i) the prompt and unconditional payment of all sums which may become payable by Borrower under the Lender Notes in full and when due in accordance with the provisions thereof, (ii) the prompt and unconditional payment and performance of any and all other Obligations of each Obligor under the Transaction Documents, and (iii) the prompt and unconditional payment and performance of any and all other indebtedness, claims or obligations of every kind and character owed by Borrower or any other Obligor to Lender now existing or hereafter created (collectively, the “Guaranteed Liabilities”). This Guaranty is irrevocable, unconditional and absolute.

(b) Any amount received by Lender from whatever source and applied by it toward the payment of the Guaranteed Liabilities shall be applied in such order of application as Lender may from time to time elect, in Lender’s sole discretion.

(c) Notwithstanding anything to the contrary herein, the liability of the Guarantor hereunder is limited to the lesser of (a) the Guaranteed Liabilities, and (b) the lowest amount that would render this Guaranty void against creditors or creditors’ representatives under any fraudulent conveyance or similar act or under Sections 544 or 548 of the United States Bankruptcy Code, as from time to time amended, minus One Dollar ($1.00).

32.02 GUARANTY TO CONTINUE. This Guaranty is a continuing promise and agreement and shall apply to and cover any and all Guaranteed Liabilities. Guarantor shall have no right to terminate this Guaranty. Termination by Lender (other than upon full and complete payment and satisfaction of all Guaranteed Liabilities) hereof shall have no effect upon, and this Guaranty shall remain in full force and effect with respect to, any Guaranteed Liability (irrespective of whether contingent, not yet mature or otherwise) existing before Guarantor’s receipt of written notice of termination from Lender.

32.03 EXTENT OF GUARANTOR’S OBLIGATION: UNLIMITED AND UNCONDITIONAL. This Guaranty is a guaranty of payment, and not of collection. If for any

reason any Guaranteed Liability shall not be paid by the Borrower or any other Obligor promptly when due (whether at maturity or acceleration) or any agreement, covenant, term or condition constituting a Guaranteed Liability is not performed or observed by Borrower or any other Obligor in accordance with their terms, Guarantor will, upon demand, pay the same promptly and/or promptly perform and observe the same or cause the same promptly to be performed or observed, regardless of (i) any defenses or rights of set-off or counterclaims that Borrower or any other Obligor may have or assert, or (ii) any limitations on the liability of Borrower or any other Obligor contained in the Transaction Documents or otherwise. The Guaranteed Liabilities are independent liabilities of Borrower and each other Obligor. To the extent Guarantor makes payment to Lender on behalf of Borrower or any other Obligor for any of the Guaranteed Liabilities, then once Lender has been paid in full Lender agrees to assign without recourse all of its debt instruments, security interests, collateral and other rights against Borrower or any other Obligor with respect to the Guaranteed Liabilities to Guarantor.

32.04 GUARANTOR’S OBLIGATIONS NOT AFFECTED. Guarantor’s liability under this Guaranty shall not be affected, modified or impaired upon the happening of any of the following at any time or from time to time, irrespective of whether Guarantor has not received notice thereof or consented therein:

(a) Changes in Guaranteed Liabilities. Any renewal, collection, settlement, release, modification, waiver, acceleration, extension or other changes in any of the Guaranteed Liabilities or any terms thereof (including, without limitation, any change in the rate of interest);

(b) Changes in Documents. Any change (whether material or otherwise) in any provisions of any Transaction Document or other documents representing the Guaranteed Liabilities, or the acceptance of amendments or substitute or additional documents, instruments or agreements relative to the Guaranteed Liabilities;

(c) Changes Regarding Collateral. Any disposition, impairment, acceptance, substitution, release (by operation of law or otherwise), transfer or waiver of, or any other action relating to, any collateral security for the Guaranteed Liabilities or any guaranty thereof; any termination, release, modification, subordination or change of rights to or liens in such collateral security or failures to obtain or perfect (or continue to obtain and perfect) any liens or rights to such collateral security; any sale, foreclosure or other action taken with respect to any such collateral security, including any use, transfer or release of any proceeds thereof, except to the extent that the proceeds are applied to, and reduce, the Guaranteed Liabilities; any consent to the transfer of any such collateral security to any person or entity whomsoever or any sale or disposition of such collateral security; or any other action which affects, alters or impairs any of Lender’s, Guarantor’s, Borrower’s, any other Obligor’s or any other party’s rights in and to such collateral security or any proceeds;

(d) Payments or Default. The acceptance of partial payments with respect to the Guaranteed Liabilities; any direction of application of payment by Borrower, any other Obligor or any other party; or the taking of or the failure to take any actions referred to in this Guaranty, any of the Transaction Documents or any other documents representing the Guaranteed Liabilities;

(e) Failure to First Collect From Others. Lender’s failure to have first initiated reasonable collection action following maturity or acceleration of the Guaranteed Liabilities with respect to any collateral security securing the Guaranteed Liabilities or following maturity or acceleration of the Guaranteed Liabilities to have first proceeded against Borrower, any other Obligor or any other guarantor for the Guaranteed Liabilities; and

(f) Changes in Rights. Any enforcement, amendment, release, waiver, variation or impairment of any of Lender’s rights against Borrower, Guarantor, any other Obligor or any other person liable for the Guaranteed Liabilities or having an interest in any collateral; anything done or omitted or neglected to be done by Lender in exercising any of its rights and remedies; the granting of time, credit or any other indulgence or concession or any power, discretion, option or right whatsoever (whether or not exercised) to Borrower, Guarantor, any other Obligor or any other person liable for the Guaranteed Liabilities; the lack of genuineness, validity or enforceability of any document evidencing or relating to the Guaranteed Liabilities; the failure by Lender to give any notice to Guarantor, any other Obligor or any other person or entity whatsoever; any change in relationship among Borrower, Guarantor or any other Obligor or any termination of such relationship; or any of any Lender’s other dealings or any other matter or thing.

32.05 OTHER WAIVERS, CONSENTS AND AGREEMENTS OF GUARANTOR. Guarantor hereby waives and agrees not to claim, assert or take advantage of (i) the incapacity or lack of authority of Borrower, Guarantor, any other Obligor or any other person, (ii) any defense arising from the failure of Lender to file or enforce a claim against Borrower, Guarantor, any other Obligor or any other person (whether in bankruptcy or otherwise) or from any election of remedies; (iii) notice of creation, renewal, extension or accrual of any of the Guaranteed Liabilities; or (iv) the lack of presentment, demand for payment, protest for non-payment, notice of discharge, dishonor, protest, notice of non-payment or other default of the Guaranteed Liabilities, notice of acceptance of this Guaranty or any document evidencing or relating to the Guaranteed Liabilities. Except as otherwise expressly provided herein, it is the intent hereof that Guarantor shall remain liable until the payment and satisfaction of all Guaranteed Liabilities notwithstanding any liquidation or insolvency or bankruptcy proceeding filed by or against Borrower, Guarantor, any other Obligor or any other person. If all or any part of any payment at any time made by Borrower, Guarantor, any other Obligor or any other person to apply to any of the Guaranteed Liabilities is or must be rescinded or returned by Lender for any reason (including, without limitation, the bankruptcy of Borrower or Guarantor), Guarantor will (notwithstanding the revocation or termination of this Guaranty or any document evidencing or relating to the Guaranteed Liabilities), remain liable for the full amount so rescinded or returned as if such amount had never been received by Lender.

32.06 INFORMATION REGARDING BORROWER AND OTHERS. Guarantor represents and warrants to Lender that this Guaranty is executed at Borrower’s request, that Guarantor has determined it to be in its best interest to issue this Guaranty, and that Guarantor has received adequate consideration therefor. Guarantor further represents and warrants (i) that Guarantor has established adequate means of obtaining from Borrower, on a continuing basis, information pertaining to the Guaranteed Liabilities, including, without limitation, a copy of each of the Transaction Documents and all other matters relating to Borrower and each other Obligor that are relevant to Guarantor’s obligations hereunder; (ii) that Guarantor is now and will

continue to be familiar with the operations of the Borrower; (iii) that Guarantor is not relying upon Lender to supply, now or in the future, any such information or any other information bearing on the risk of nonpayment of any of the Guaranteed Liabilities or of any guaranty thereof or otherwise relating to Borrower, any other Obligor or the Guaranteed Liabilities; (iv) that Guarantor will receive valuable direct or indirect benefits as a result of the transactions representing the Guaranteed Liabilities, and that such benefits will constitute reasonably equivalent value and/or fair consideration; and (v) that Borrower and each Obligor has acted in good faith in connection with the guaranty given by Guarantor pursuant to this Guaranty and the transactions contemplated by the Transaction Documents and each other document representing a Guaranteed Liability. Guarantor hereby waives and relinquishes any duty on the part of Lender to disclose to Guarantor, any matter, fact or thing now or hereafter known to Lender relating to the business, operation, condition or assets of, or otherwise pertaining to, Borrower, any other Obligor or any other person or entity. Lender need not inquire into the powers of Borrower, any other Obligor or their respective officers, employees, representatives, shareholders, partners, agents or other persons acting or purporting to act on their behalf, and any Guaranteed Liabilities made or created in reliance upon the professed exercise of such power shall be guaranteed hereunder. Guarantor hereby consents and approves of the Transaction Documents and all terms and agreements previously or hereafter made by Lender with Borrower or any other person liable for the payment of any of the Guaranteed Liabilities.

32.07 COLLATERAL. Lender shall not be liable for any failure to collect or, realize upon any Guaranteed Liabilities or any collateral which is security therefor or any guaranty thereof or collateral which is security for such guaranty, or for any delay in so doing; nor shall Lender be under any obligation to take any action with regard thereto unless otherwise expressly provided herein.

32.08 SECURITY. The Guaranteed Liabilities under this Guaranty are secured by the terms of that certain Amended and Restated Stock Pledge Agreement (Subsidiary) dated as of even date hereof by and between Guarantor and Lender.

32.09 SUBORDINATION. Guarantor acknowledges that it may advance funds to Borrower or any other Obligor or have subrogation, contribution or other rights against Borrower or any other Obligor now or in the future (the “Guarantor Claims”). Guarantor hereby subordinates any and all rights to the repayment or reimbursement of Guarantor Claims to the Guaranteed Liabilities. Guarantor agrees that so long as the Guaranteed Liabilities shall remain outstanding, it will not request or accept any repayment or reimbursement of any portion of Guarantor Claims or enforce any rights relating thereto, and that any such repayment or reimbursement received by it will be promptly paid to Lender, to be applied to the Guaranteed Liabilities in accordance with the Transaction Documents or any other documents representing the Guaranteed Liabilities.

This Agreement shall be governed by and construed in accordance with the internal laws of the State of Illinois, and this Agreement may not be changed, nor may any term or condition be waived, modified or discharged orally but only by an agreement in writing, signed by the party against whom enforcement of any waiver, change, modification or discharge is sought.
