Section 2(a): Agreement to Purchase Firm Shares.

Subject to the terms and conditions and in reliance upon the representations, warranties, covenants, and agreements set forth herein, the Company agrees to issue and sell to the several Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, the respective number of Firm Shares set forth opposite such Underwriter's name in Schedule I hereto, at the Purchase Price of $18.80 per share. The total number of Firm Shares to be sold by the Company is 20,000,000. The total aggregate purchase price for the Firm Shares payable by the Underwriters to the Company shall be $376,000,000 (representing 20,000,000 Firm Shares multiplied by the Purchase Price of $18.80 per share).

The public offering price of the Firm Shares shall be $20.00 per share. The underwriting discount applicable to the Firm Shares shall be $1.20 per share, representing 6.0% of the public offering price. The total underwriting discount on the Firm Shares shall be $24,000,000 (representing 20,000,000 Firm Shares multiplied by $1.20 per share). The base gross proceeds to the Company from the sale of the Firm Shares shall be $400,000,000, and the net proceeds to the Company from the Firm Shares (before deduction of expenses payable by the Company) shall be $376,000,000.

All Shares to be sold in this offering are primary shares to be newly issued by the Company. There are no secondary sales or selling stockholders in connection with this offering.

The obligations of each Underwriter to purchase the Firm Shares shall be several and not joint. No Underwriter shall be obligated to purchase any Firm Shares that any other Underwriter has agreed but failed to purchase, except as provided in Section 10 hereof.

Section 2(b): Overallotment Option (Option Shares).

In addition to the Firm Shares, the Company hereby grants to the several Underwriters an option (the "Overallotment Option") to purchase, severally and not jointly, up to 3,000,000 Option Shares at the Purchase Price of $18.80 per share, solely for the purpose of covering overallotments, if any, made in connection with the offering of the Firm Shares. The Overallotment Option shall be exercisable at any time, and from time to time, in whole or in part, within thirty (30) days from the date of the Prospectus (i.e., on or before March 9, 2024), by written notice from the Representative to the Company setting forth the number of Option Shares as to which the Overallotment Option is being exercised and the date on which the Option Shares are to be delivered (the "Option Closing Date").

If the Overallotment Option is exercised in full, the additional gross proceeds to the Company from the sale of the Option Shares shall be $60,000,000 (representing 3,000,000 Option Shares multiplied by the public offering price of $20.00 per share), the additional underwriting discount shall be $3,600,000 (representing 3,000,000 Option Shares multiplied by $1.20 per share), and the additional net proceeds to the Company from the Option Shares (before deduction of expenses) shall be $56,400,000 (representing 3,000,000 Option Shares multiplied by the Purchase Price of $18.80 per share).

Accordingly, the maximum total gross proceeds to the Company from the offering (assuming exercise of the Overallotment Option in full) shall be $460,000,000. The maximum total underwriting discount shall be $27,600,000. The maximum total net proceeds to the Company (before deduction of expenses) shall be $432,400,000.

The Option Shares shall be allocated among the several Underwriters pro rata in proportion to their respective Firm Share commitments as set forth in Schedule I hereto. The number of Option Shares to be purchased by each Underwriter shall be determined by multiplying the total number of Option Shares to be purchased by a fraction, the numerator of which is the number of Firm Shares set forth opposite such Underwriter's name in Schedule I and the denominator of which is the total number of Firm Shares.

Section 2(c): Payment and Delivery — Firm Shares.

Delivery of the Firm Shares shall be made on the Closing Date (February 13, 2024) through the facilities of The Depository Trust Company ("DTC"), or at such other place as may be agreed upon by the Representative and the Company, against payment of the aggregate Purchase Price therefor by wire transfer of immediately available funds to the account designated in writing by the Company. The Company shall designate in writing to the Representative, no later than two (2) full business days prior to the Closing Date, the account to which such wire transfer shall be made.

The Firm Shares shall be registered in such names and in such denominations as the Representative shall request in writing at least two (2) full business days prior to the Closing Date. It is understood that the Representative may direct that certificates for the Firm Shares, if any, be issued in the names of such dealers as may have been selected by the Underwriters for selling group purposes, and that any Shares deposited with DTC shall be registered in the name of Cede & Co., as nominee of DTC.

Continental Share Services, Inc. shall act as the transfer agent and registrar for the common stock. The common stock of the Company has been made eligible for deposit and book-entry transfer through the facilities of DTC (CUSIP: 039217105). The Company shall cooperate in all respects necessary to cause the Firm Shares to be eligible for such deposit and transfer on or before the Closing Date.

Section 2(d): Payment and Delivery — Option Shares.

Delivery of the Option Shares shall be made on the applicable Option Closing Date through the facilities of DTC, or at such other place as may be agreed upon by the Representative and the Company, against payment of the aggregate purchase price for such Option Shares by wire transfer of immediately available funds to the account designated in writing by the Company. If the Overallotment Option is exercised, settlement of the Option Shares shall occur no later than three (3) business days after the date on which the Representative delivers notice of exercise to the Company, or on such later date as may be agreed upon by the Representative and the Company; provided, however, that the Option Closing Date shall not be earlier than the Closing Date.
