FIRST BUSINESS FINANCIAL SERVICES, INC., a Wisconsin corporation (the “Issuer”), for value received, hereby promises to pay to                         , the principal sum of                          Dollars (U.S.) ($        ) plus accrued but unpaid interest on September 1, 2024 (the “Maturity Date”) and to pay interest in arrears on such principal amount: (a) through but excluding September 1, 2019, at the rate of 6.50% per annum (computed on the basis of a 360-day year of twelve 30-day months) from             , 2014, or from the most recent Fixed Interest Payment Date to which interest has been paid or duly provided, on March 1 and September 1 of each year (each, a “Fixed Interest Payment Date”), commencing March 1, 2015; and (b) beginning on September 1, 2019, at the rate per annum, reset quarterly, equal to the then-current three-month LIBOR rate plus 470 basis points (computed on the basis of a 360-day year and the number of days actually elapsed) from September 1, 2019, or from the most recent Floating Interest Payment Date to which interest has been paid or duly provided, on March 1, June 1, September 1 and December 1 of each year (each, a “Floating Interest Payment Date”), commencing December 1, 2019, until the principal hereof is paid or made available for payment. “LIBOR” means the rate as published by Bloomberg (or other commercially available source providing quotations of such rate as selected by the Paying Agent from time to time) at approximately 11:00 a.m., London time, two Business Days prior to the commencement of such interest period, as the rate for dollar deposits in the London interbank market with a three-month maturity. If such rate is not available at such time for any reason, then the rate for that interest period will be determined by such alternate method as reasonably selected by the Paying Agent. “Interest period” means each three-month period beginning on a Floating Interest Payment Date.

Any payment of principal of or interest on this Fixed-to-Floating Rate Subordinated Note (this “Note”) that would otherwise become due and payable on a day which is not a Business Day shall become due and payable on the next succeeding Business Day, with the same force and effect as if made on the date for payment of such principal or interest, and no interest shall accrue in respect of such payment for the period after such day. The term “Business Day” means any day that is not a Saturday or Sunday and that, in the City of New York, New York, Wilmington, Delaware or the State of Wisconsin, is not a day on which banking institutions are generally authorized or obligated by law to close.

Unless the certificate of authentication hereon has been executed by the Paying Agent (as defined in the Fiscal and Paying Agency Agreement) by the manual signature of one of its authorized signatories, this Note shall not be valid or obligatory for any purpose.

This Note is one of a duly authorized issue of notes of the Issuer designated as Fixed-to-Floating Rate Subordinated Notes due September 1, 2024 (herein called the “Subordinated Notes”), in an aggregate principal amount of $15,000,000. Reference is hereby made to the Purchase Agreement dated as of August 26, 2014 between the Issuer and the lenders referred to therein (the “Purchase Agreement”) (copies of which are on file and available for inspection during normal business hours at the offices of the Issuer), for a statement of the further rights of the holders from time to time of the Subordinated Notes (collectively, the “Noteholders”) and the further rights, limitations of rights, duties and indemnities thereunder of the Issuer and of the terms upon which the Subordinated Notes are, and are to be, authenticated and delivered.

The indebtedness of the Issuer evidenced by the Subordinated Notes, including the principal and interest on this Note, shall be subordinate and junior in right of payment to the following, whether now outstanding or subsequently created, assumed or incurred (collectively, “Senior Indebtedness”): (a) all indebtedness of the Issuer for money borrowed, whether or not evidenced by bonds, debentures, securities, notes or other written instruments; (b) any deferred obligations of the Issuer for the payment of the purchase price of property or assets acquired other than in the ordinary course of business; (c) all obligations, contingent or otherwise, of the Issuer in respect of any letters of credit, bankers’ acceptances, security purchase facilities and similar credit transactions; (d) any capital lease obligations of the Issuer; (e) all obligations of the Issuer in respect of interest rate swap, cap or other agreements, interest rate future or option contracts, currency swap agreements, currency future or option contacts, commodity contracts and other similar arrangements; (f) all obligations of the type referred to in clauses (a) through (e) of other persons for the payment of which the Issuer is responsible or liable as obligor, guarantor or otherwise; and (g) all obligations of the types referred to in clauses (a) through (f) of other persons secured by a lien on any property or asset of the Issuer; except “Senior Indebtedness” does not include (i) the Subordinated Notes, (ii) any obligation that by its terms is on parity with the Subordinated Notes, (iii) any indebtedness between the Issuer and any of its subsidiaries or affiliates (iv) the $7.926 million of subordinated notes originally issued by the Issuer in 2012 and 2013 (the “Existing Subordinated Indebtedness”) or (v) the Junior Subordinated Indebtedness (as defined below).

In the event of any insolvency, dissolution, assignment for the benefit of creditors, reorganization, restructuring of debt, marshaling of assets and liabilities or similar proceedings or any liquidation or winding up of or relating to the Issuer, whether voluntary or involuntary, holders of Senior Indebtedness shall be entitled to be paid in full before any payment shall be made on account of the principal of or interest on the Subordinated Notes, including this Note. In the event of any such proceeding, after payment in full of all sums owing with respect to the Senior Indebtedness, the Noteholders, together with the holders of any obligations of the Issuer ranking on a parity with the Subordinated Notes (including, without limitation, the Existing Subordinated Indebtedness), shall be entitled to be paid from the remaining assets of the Issuer the unpaid principal thereof, and the unpaid interest thereon before any payment or other distribution, whether in cash, property or otherwise, shall be made on account of any capital stock or any present or future obligations of the Issuer ranking junior to the Subordinated Notes (collectively, “Junior Subordinated Indebtedness”), which includes (i) any obligation that by its terms is subordinated to the Subordinated Notes and (ii) the $10.3 million junior subordinated notes due 2038 and guaranty issued by the Issuer in connection with the trust preferred securities of FBFS Statutory Trust II (the “Trust Preferred Securities”) and all other debt securities and guarantees in respect of similar preferred securities or other securities issued by a financing vehicle of the Issuer and guaranteed by the Issuer that rank pari passu with, or junior to, the Trust Preferred Securities.

If there shall have occurred and be continuing (a) a default in any payment with respect to any Senior Indebtedness, or (b) an event of default with respect to any Senior Indebtedness as a result of which the maturity thereof is accelerated, unless and until such payment default or event of default shall have been cured or waived or shall have ceased to exist, no payments shall be made by the Issuer with respect to the Subordinated Notes. The provisions of this paragraph shall not apply to any payment with respect to which the immediately preceding paragraph of this Section would be applicable.

Nothing herein shall impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Note in accordance with its terms. Nothing herein shall act to prohibit, limit or impede the Issuer from issuing additional debt of the Issuer having the same rank as the Subordinated Notes or which may be junior or senior in rank to the Subordinated Notes.

The Issuer shall not consolidate with or merge into another entity or convey, transfer or lease its properties and assets substantially as an entirety to any person, unless:

(a)    the continuing entity formed by such consolidation or into which the Issuer is merged or the person which acquires by conveyance or transfer or which leases the properties and assets of the Issuer substantially as an entirety shall be a corporation, association or general partnership or other legal entity organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and expressly shall assume, by a supplemental agreement executed and delivered to the Noteholders, the due and punctual payment of the principal of and any premium and interest on the Subordinated Notes according to their terms, and the due and punctual performance of all covenants and conditions hereof on the part of the Issuer to be performed or observed; and

(b)    immediately after giving effect to such transaction, no Event of Default (as defined below), and no event which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing.

Subject to the receipt of any necessary regulatory approval, the Issuer shall have the right, at its option, to redeem this Note, in whole or in part, on any Floating Interest Payment Date on or after September 1, 2019, at a price equal to 100% of the principal amount of the Subordinated Note redeemed, plus accrued but unpaid interest thereon to, but excluding, the redemption date. Any such redemption shall be pro rata among all holders of the Subordinated Notes. If the Issuer redeems less than all of the Subordinated Notes at any time, the Issuer will select the Subordinated Notes to be redeemed in minimum principal amounts of $200,000 and multiples of $1,000 in excess thereof. Notices of redemption will be mailed by first class mail, postage prepaid, or emailed (with delivery receipt requested) at least 30 but not more than 60 days before the redemption date, which notice may be conditional, to each Noteholder at such Noteholder’s registered mailing address or email address. On and after the redemption date, interest ceases to accrue on Subordinated Notes or portions of them called for redemption. This Note is not subject to redemption at the option of the Noteholder.

Additionally, subject to the receipt of any necessary regulatory approval, the Issuer shall have the right, at its option, to redeem all of the Subordinated Notes in whole if the Issuer receives an opinion of counsel experienced in such matters to the effect that as a result of any amendment to or change (including any announced prospective change) in the laws, rules or regulations of the United States or any political subdivision or taxing authority thereof or therein, or as a result of any official administrative

pronouncement or judicial action or decision interpreting or applying such laws, rules or regulations, which amendment, clarification, change, administrative action or decision is enacted, effective, promulgated or announced on or after August 26, 2014: (a) there is more than an insubstantial risk that the interest payable on the Subordinated Notes is not, or within 90 days of the date of such opinion, will not be, deductible by the Issuer, in whole or in part, for United States federal income tax purposes; (b) there is more than an insubstantial risk that the Issuer will not, within 90 days of the date of such opinion, be entitled to treat an amount equal to the aggregate liquidation amount of the Subordinated Notes as Tier 2 Capital (as defined in the Purchase Agreement); or (c) there is more than an insubstantial risk that the Issuer is or, within 90 days of the date of such opinion, will be considered, an “investment company” that is required to be registered under the Investment Company Act of 1940, as amended. Such redemption shall occur at a price equal to 100% of the principal amount of the Subordinated Note redeemed, plus accrued but unpaid interest thereon to, but excluding, the redemption date.

If any of the following events shall occur and be continuing (each an “Event of Default”):

(a)    the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or shall consent to the appointment of a receiver, liquidator, trustee or other similar official in any liquidation, insolvency or similar proceeding with respect to the Issuer or all or substantially all of its property, or shall make an assignment for the benefit of creditors; or

(b)    a court or other governmental agency or body having jurisdiction on the premises shall enter a decree or order for the appointment of a receiver, liquidator, trustee or other similar official in any liquidation, insolvency or similar proceeding with respect to the Issuer or all or substantially all of the property of the Issuer, or for the winding up of the affairs or business of the Issuer and such decree or order shall have remained in force for 60 days;

then, and in each such case, unless the principal of this Note already shall have become due and payable, the holder of this Note, by notice in writing to the Issuer and to the Paying Agent, may declare the principal amount of this Note to be due and payable immediately and, upon any such declaration the same shall become and shall be immediately due and payable. The Issuer waives demand, presentment for payment, notice of nonpayment, notice of protest, and all other notices.

The Paying Agent, within ninety (90) days after the receipt of written notice from the Issuer or from any Noteholder of the occurrence of an Event of Default with respect to this Note, shall mail to all Noteholders, at their addresses shown on the Security Register (as defined below), such written notice of Event of Default, unless such Event of Default shall have been cured or waived before the giving of such notice as certified by the Issuer in writing.

In the event of failure by the Issuer to make any required payment of principal or interest on this Note (and, in the case of payment of interest, such failure to pay shall have continued for 30 calendar days), the Issuer will, upon demand of the holder, pay to the holder the whole amount then due and payable on this Note for principal and interest (without acceleration), with interest on the overdue principal and interest at the rate borne by this Note, to the extent permitted by applicable law. If the Issuer fails to pay such amount upon such demand, the holder may, among other things, institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Issuer and collect the amounts adjudged or decreed to be payable in the manner provided by law out of the property of the Issuer.

Upon the occurrence of a failure by the Issuer to make any required payment of principal or interest on the Note, the Issuer shall not (i) declare or pay any dividends or distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Issuer’s capital stock or make any guarantee payments with respect to the foregoing or (ii) make any payment of principal or interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Issuer that rank pari passu in all respects with or junior in interest to the Subordinated Notes (other than, with respect to clauses (i) and (ii) above, (a) repurchases, redemptions or other acquisitions of shares of capital stock of the Issuer in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of one or more employees, officers, directors or consultants, in connection with a dividend reinvestment or stock purchase plan or in connection with the issuance of capital stock of the Issuer (or securities convertible into or exercisable for such capital stock) as consideration in an acquisition transaction entered into prior to the applicable failure to make a required payment, (b) as a result of any exchange or conversion of any class or series of the Issuer’s capital stock for any class or series of the Issuer’s capital stock or of any class or series of the Issuer’s indebtedness for any class or series of the Issuer’s capital stock, (c) the purchase of fractional interests in shares of the Issuer’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged, (d) any declaration of a dividend in connection with any shareholders’ rights plan, or the issuance of rights, stock or other property under any shareholders’ rights plan, or the redemption or repurchase of rights pursuant thereto or (e) any dividend in the form of stock, warrants, options or other rights in the same stock as that on which the dividend is being paid or ranks pari passu with or junior to such stock and any cash payments in lieu of fractional shares issued in connection therewith).

8.    Payment Procedures. Payment of the principal and interest payable on the Maturity Date will be made by check, or by wire transfer in immediately available funds to a bank account in the United States designated by the registered holder of this Note if such holder shall have previously provided wire instructions to the Paying Agent, upon presentation and surrender of this Note at the office of the Paying Agent in Wilmington, Delaware or at such other place or places as the Paying Agent shall designate by notice to the Noteholders, provided that this Note is presented to the Paying Agent in time for the Paying Agent to make such payments in such funds in accordance with its normal procedures.

Any such issuance shall be made pursuant to another offering document and will either be registered or issued pursuant to an exemption from registration under the Securities Act of 1933, as amended, or similar laws or regulations issued by the applicable banking agency.
