(the “Company”) under the HEARTLAND FINANCIAL USA, INC. 2020 LONG-TERM INCENTIVE PLAN (the “Plan”). The restricted stock units awarded by this Award Agreement (this “Agreement”) shall be subject to the terms of the Plan and the terms set forth in this Agreement. All capitalized terms used in this Agreement and not otherwise defined have the meaning assigned to them in the Plan. Section 1. Award. The Company hereby grants to the Participant an award of restricted stock units (each such unit, an “RSU”), where each RSU represents the right of the Participant to receive one share of Company stock (“Share”) in the future, subject to the terms of this Agreement and the Plan. For all purposes of this Agreement: The “Participant” is: %%FIRST_NAME_MIDDLE_NAME_LAST_NAME%- % The “Xxxxx Date” is: %%OPTION_DATE%-% The number of RSUs is: %%TOTAL_SHARES_GRANTED%-% Section 2. Vesting of RSUs. (a) Vesting. To the extent earned in accordance with Section 2(b), and subject to forfeiture prior to vesting in accordance with Section 2(c), the RSUs shall vest on the Measurement Date (as defined in Section 2(b)) or such earlier date pursuant to Section 2(c). Shares shall be delivered based upon vesting of RSUs pursuant to and subject to Section 3 below. The price at which the RSUs shall vest is the fair market value of Company stock at closing on the business day prior to the Measurement Date. (b) Earning of RSUs. The RSUs shall be earned based upon the financial performance of the Company as set forth in Exhibit A (the “Performance Targets”) during the three fiscal years commencing with the fiscal year in which the Grant Date occurs (the “Three- Year Performance Period”). The Committee shall determine whether the RSUs have been earned based upon the Performance Targets at its first meeting (the date of such meeting, the “Measurement Date”) after measurement of performance in relation to the Performance Targets is attainable for the last fiscal year of the Three-Year Performance Period, and the Company shall advise the Participant as soon as practicable thereafter of the number of RSUs that have been earned; provided, however, that no RSUs shall become earned if there exists as of the Measurement Date, as determined by the Committee, a material weakness (a “Material Weakness”) in the safety, soundness or compliance (e.g., a regulatory memorandum of understanding, or a material weakness in internal control over financial reporting) of the Company. In determining whether the RSUs have been earned based upon the Performance Targets, the Committee shall consider the effects of the following items, to the extent identified

2 4821-9786-2960\2 in the audited financial statements of the Company as of and for the fiscal years ended during the Three-Year Performance Period, or in the Management Discussion and Analysis section of the Company’s annual reports made available to its stockholders during the Three-Year Performance Period: (i) extraordinary, unusual or nonrecurring items of gain or loss, (ii) gains or losses on the disposition of a business, (iii) changes in tax or accounting principles, regulations or laws or (iv) mergers or acquisitions. (c) Forfeiture and Special Vesting of RSUs. Notwithstanding the foregoing provisions of Section 2(b): (i) Any RSUs that have not been earned as of the Measurement Date based upon failure to meet the Performance Targets shall expire and be forfeited on, and as of, the Measurement Date. (ii) Any RSUs that have not been earned as of the Measurement Date based upon failure to remediate a Material Weakness shall expire and be forfeited on, and as of, the Measurement Date. (iii) If a Participant’s Termination of Service occurs prior to the Measurement Date due to termination of the Participant’s employment by the Participant’s employer (with or without Cause) or by the Participant voluntarily (other than due to Qualifying Retirement), any RSUs held by the Participant shall expire and shall be forfeited as of the date of employment termination. (iv) If a Participant’s Termination of Service occurs prior to the Measurement Date due to the Participant’s Disability or death, then the RSUs shall continue to remain outstanding until the Measurement Date and shall become vested, to the extent earned, as of and on the Measurement Date. (v) If the Participant’s Termination of Service occurs prior to the Measurement Date due to a Qualifying Retirement, then the RSUs shall continue to remain outstanding until the Measurement Date and shall become vested, to the extent earned, as of and on the Measurement Date. For such purposes, a “Qualifying Retirement” means a voluntary Termination of Services by the Participant on or after the date the Participant reaches the age of 62, and provided that (A) the Participant has provided at least five (5) years of full-time equivalent services to the Company or a Subsidiary through the date of such Termination of Services; (B) the Participant covenants that the Participant shall not engage in any full-time employment with any entity thereafter (although Participant shall be entitled to engage in part- time employment, including services as a member of a board of directors or similar body, with an entity that does not compete with the Company or any Subsidiary) unless such employment has been approved in writing by the Chair of the Committee; (C) the Participant executes a general release and waiver of claims against the Company at the time of such Termination of Services; and (D) the Participant executes a confidentiality, non-solicitation, and non- competition agreement with the Company at the time of such Termination of Service. Consistent with Section 5.2 of the Plan, any question regarding whether a voluntary Termination of Service constitutes a Qualifying Retirement shall be determined by the Committee and the decision of the Committee shall be final and binding upon the Participant.

3 4821-9786-2960\2 (vi) Immediately upon a Change in Control, if the obligations under this Agreement are not assumed by the Company or its successor in such Change in Control, all RSUs that have not been previously forfeited shall become vested as if the Company had achieved 100% of the Performance Targets immediately prior to the Change in Control. Otherwise, if the obligations under this Agreement are assumed by the Company or its successor in such Change in Control, and if a Participant’s employment by the Company or Bank or successor of the Company or Bank shall become subject to a Termination of Service within the period beginning six months prior to a Change in Control and ending 24 months after a Change in Control, all RSUs then held by the Participant shall become vested as if the Company had achieved 100% of the Performance Targets immediately prior to the Change in Control, upon the later to occur of the Termination of Service or Change in Control. The foregoing provisions are subject to any forfeiture and expiration provisions otherwise applicable to the RSUs. Section 3. Settlement of RSUs.

Except as may be provided otherwise by the Committee, such withholding obligations may be satisfied at the election of the Participant (a) through debit of a deposit account held by the Participant at a bank affiliated with the Company, or (b) through the surrender of Shares to which the Participant is otherwise entitled under the Plan; provided, however, that except as otherwise specifically provided by the Committee, such Shares under clause (b) may not be used to satisfy more than the Company’s minimum statutory withholding obligation. Section 5. Non-Transferability of RSUs. Neither the RSUs awarded pursuant to this Agreement, nor any portion thereof, shall be transferable, except as designated by the Participant by will or by the laws of descent and distribution or pursuant to a domestic relations order.
