Second Amendment to Amended and Restated Credit Agreement

The undersigned, MidWestOne Financial Group, Inc., an Iowa corporation formerly known as Mahaska Investment Company (the “Borrower”), refers to the Amended and Restated Credit Agreement dated as of June 30, 2000, as amended and currently in effect between the Borrower and you (the “Bank”) (such Amended and Restated Credit Agreement as so amended being hereinafter referred to as the “Present Credit Agreement”) pursuant to which the Bank has extended, subject to the terms and conditions thereof, a revolving credit facility available to the Borrower in a principal amount not to exceed $9,000,000 at any one time outstanding. The Borrower issued to the Bank under the Present Credit Agreement its Revolving Credit Note dated as of June 30, 2000, payable to the order of the Bank in the principal amount of $9,000,000 (the “Present Revolving Credit Note”) to evidence the indebtedness outstanding on said revolving credit. The Borrower has requested that the Bank modify the terms and conditions applicable to the indebtedness evidenced by the Present Revolving Credit Note (the indebtedness evidenced by the Present Revolving Credit Note being hereinafter referred to as the “Present Revolving Credit Loans”), extend the maturity thereof, make available to the Borrower a new term loan in the amount of $6,000,000, and thus provide to the Borrower a restructured revolving credit facility and a new term loan facility covering the Present Revolving Credit Loans, all on and subject to the terms and conditions set forth below. Accordingly, this Agreement is executed and delivered by the Borrower to the Bank to set forth and confirm the terms and conditions applicable to such credit facilities and the covenants, representations and warranties of the Borrower to be made in connection therewith.

The Borrower acknowledges that it is justly and truly indebted to the Bank on the Present Revolving Credit Loans as of November 24, 2003, in the principal amount of $8,600,000 plus accrued and unpaid interest thereon. Substantially concurrently herewith, the Borrower is executing and delivering to the Bank the Notes hereinafter identified and defined. Upon satisfaction of the conditions precedent to effectiveness set forth in Section 6 hereof, the Present Revolving Credit Loans shall automatically, and without further action on the part of either the Bank or the Borrower, become evidenced by the Revolving Credit Note referred to in Section 1.1 below and, to that extent, the Revolving Credit Note is issued in renewal of, and evidence the same indebtedness formerly evidenced by, the Present Revolving Credit Note, as well as evidencing all additional Revolving Loans to be made pursuant hereto. All of the Present Revolving Credit Loans shall, for all purposes of this Agreement, be treated as Revolving Loans under this Agreement on the date the conditions precedent to effectiveness set forth in Section 6 hereof have been satisfied or duly waived in writing by the Bank. Simultaneously with such satisfaction or waiver of such conditions precedent, the Borrower shall pay to the Bank all unpaid interest and commitment fees accrued to such date on or in connection with the Present Revolving Credit Loans, and the existing defaults by the Borrower under Section 7.6 of the Present Credit Agreement (Non-Performing Assets) for the periods ended March 31, 2003, and

June 30, 2003, and September 30, 2003, shall be deemed waived hereby. Except as specifically waived hereby, all of the terms of the Present Credit Agreement as amended and restated by this Agreement shall be and remain in full force and effect.

Section 1.1. Revolving Credit. Subject to the terms and conditions hereof, the Bank agrees to extend a revolving credit (the “Revolving Credit”) to the Borrower which may be availed of by the Borrower from time to time during the period from and including the date hereof to but not including the Revolving Credit Termination Date, at which time the commitment of the Bank to extend credit under the Revolving Credit shall expire. The Revolving Credit may be utilized by the Borrower in the form of loans (individually a “Revolving Loan” and collectively the “Revolving Loans”), provided that the aggregate principal amount of Revolving Loans outstanding at any one time shall not exceed $9,000,000 (the “Revolving Credit Commitment”, as such amount may be reduced pursuant to Section 2.4 hereof). The Revolving Loans shall be made against and evidenced by a single promissory note of the Borrower in the form (with appropriate insertions) attached hereto as Exhibit A (the “Revolving Note”). Without regard to the principal amount of the Revolving Note stated on its face, the actual principal amount at any time outstanding and owing by the Borrower on account of the Revolving Note shall be the sum of all Revolving Loans made hereunder less all payments of principal actually received by the Bank. During the period from and including the date hereof to but not including the Revolving Credit Termination Date, the Borrower may use the Revolving Credit Commitment by borrowing, repaying and reborrowing Revolving Loans in whole or in part, all in accordance with the terms and conditions of this Agreement.

Section 1.2. Term Loan. Subject to the terms and conditions hereof, the Bank agrees to make a term loan (the “Term Loan”) to the Borrower concurrently herewith in the principal amount of $6,000,000. The Term Loan shall be made against and evidenced by a promissory note of the Borrower in the form (with appropriate insertions) attached hereto as Exhibit B (the “Term Note”). The Borrower shall make semi-annual principal installment payments on the Term Loan on the last day of May and November of each year, commencing May 31, 2004, with the amount of each such principal installment to equal the amount set forth in Column B below shown opposite of the relevant due date as set forth in Column A below:

, it being agreed that the final payment of both principal and interest not sooner paid on the Term Loan shall be due and payable on November 30, 2006, the final maturity thereof.

Section 1.3. Manner and Disbursement of Loans. The Borrower shall give written or telephonic notice to the Bank (which notice shall be irrevocable once given) by no later than 11:00 a.m. (Chicago time) on the date the Borrower requests the Bank to make a Loan hereunder. Each such notice shall specify the date of the Loan requested (which must be a Business Day) and the amount of such Loan. The Borrower agrees that the Bank may rely upon any written or telephonic notice given by any person the Bank in good faith believes is an Authorized Representative without the necessity of independent investigation. Subject to the provisions of Section 6 hereof, the proceeds of each Loan shall be made available to the Borrower at the principal office of the Bank in Chicago, Illinois, in immediately available funds.

Section 2.1. Interest. The outstanding principal balance of the Loans shall bear interest (which the Borrower hereby promises to pay at the rates and at the times set forth herein) prior to maturity (whether by lapse of time, acceleration or otherwise) at the rate per annum determined by subtracting (but not below zero) 0.30% per annum from the Prime Rate as in effect from time to time and after maturity (whether by lapse of time, acceleration or otherwise), whether before or after judgment, until payment in full thereof at the rate per annum determined by adding 3% to the Prime Rate as in effect from time to time. Any change in the interest rate on the Loans resulting from a change in the Prime Rate shall be effective on the date of the relevant change in the Prime Rate. Interest on the Loans shall be computed on the basis of a year of 360 days for the actual number of days elapsed. Interest on the Loans shall be payable quarterly in arrears on the last day of each calendar quarter in each year (commencing on the first such date occurring after the date hereof) and at maturity, and interest after maturity shall be due and payable on demand.

Section 2.2. Revolving Credit Commitment Fee. For the period from and including the date hereof to but not including the Revolving Credit Termination Date, the Borrower shall pay to the Bank a commitment fee at the rate of 0.125% per annum (computed on the basis of a year of 360 days for the actual number of days elapsed) on the average daily unused portion of the Revolving Credit Commitment. Such commitment fee shall be payable quarterly in arrears on the last day of each calendar quarter in each year (commencing June 30, 2000) and on the Revolving Credit Termination Date.

Section 2.3. Prepayments. (a) Voluntary Prepayments. The Borrower shall have the privilege of prepaying without premium or penalty and in whole or in part any Note at any time upon notice to the Bank prior to 12:00 noon (Chicago time) on the date fixed for prepayment. If such prepayment prepays the Term Note (in whole or in part) or the Revolving Note in full accompanied by the termination in whole of the Revolving Credit Commitment, each such prepayment shall be made together with accrued interest thereon to the date of prepayment.

(b) Mandatory Prepayments. The Borrower shall, on each date the Revolving Credit Commitment is reduced pursuant to Section 2.4 hereof, prepay the Revolving Loans by

the amount, if any, necessary to reduce the aggregate principal amount of the Revolving Loans then outstanding to the amount to which the Revolving Credit Commitment has been so reduced.

Section 2.4. Terminations. (a) Optional Terminations. The Borrower shall have the right at any time and from time to time, upon one (1) Business Day prior notice to the Bank, to terminate without premium or penalty and in whole or in part (but if in part, then in an amount not less than $100,000) the Revolving Credit Commitment, provided that the Revolving Credit Commitment may not be so reduced to an amount less than the aggregate principal amount of the Revolving Loans then outstanding. Any termination of the Revolving Credit Commitment pursuant to this Section may not be reinstated.

(b) Mandatory Termination. After the occurrence of a Change of Control, the Bank may, by written notice to the Borrower at any time on or before the date occurring 90 days after the date the Borrower notifies the Bank of such Change of Control, terminate the Revolving Credit Commitment and all other Obligations of the Bank hereunder on the date stated in such notice (which shall in no event be sooner than 30 days after the occurrence of such Change of Control). On the date the Revolving Credit Commitment is so terminated, all Outstanding Obligations (including, without limitation, all principal of and accrued but unpaid interest on the Term Note, as well as the Revolving Note) shall forthwith be due and payable without further demand, presentment, protest, or notice of any kind.

Section 2.5. Place and Application of Payments. All payments of principal, interest, and all other Obligations payable under the Loan Documents shall be made to the Bank at its office at 111 West Monroe Street, Chicago, Illinois (or at such other place as the Bank may specify) no later than 12:00 noon (Chicago time) on the date any such payment is due and payable. Payments received by the Bank after 12:00 noon (Chicago time) shall be deemed received as of the opening of business on the next Business Day. All such payments shall be made in lawful money of the United States of America, in immediately available funds at the place of payment, without set-off or counterclaim. Any amount prepaid under the Revolving Credit may, subject to the terms and conditions hereof, be borrowed, repaid and borrowed again. No amount prepaid on the Term Note may be reborrowed, and partial prepayments of the Term Note shall be applied to the several installments thereof in the inverse order of maturity.

Section 2.6. Notations. All Loans made against a Note shall be recorded by the Bank on its books and records or, at its option in any instance, endorsed on the reverse side of such Note or on a schedule attached thereto and the unpaid principal balance so recorded or endorsed by the Bank shall be prima facie evidence in any court or other proceeding brought to enforce such Note of the principal amount remaining unpaid thereon; provided that the failure of the Bank to record any of the foregoing shall not limit or otherwise affect the obligation of the Borrower to repay the principal amount of such Note together with accrued interest thereon. Prior to any negotiation of any Note, the Bank shall record on the reverse side thereof or on a schedule thereto the status of all amounts evidenced thereby.

The payment and performance of the Obligations shall at all times be secured by all of the issued and outstanding capital stock (except for directors’ qualifying shares as required by law) of each Subsidiary of the Borrower, whether now owned or hereafter formed or acquired, pursuant to a Pledge and Security Agreement dated as of October 17, 1997, as amended, between the Borrower and the Bank (the Pledge and Security Agreement, and all other instruments and documents as shall from time to time secure the Obligations or any part thereof, being hereinafter referred to as the “Collateral Documents”).
