2. Acceptance and Purchase. The offer of Securities to Selected Dealers will be made on the basis of a reservation of Securities and an allotment against subscriptions. Any application for additional Securities will be subject to rejection in whole or in part. Subscription books may be closed by the Manager at any time in its discretion without notice and the right is reserved to reject any subscription in whole or in part. We agree to purchase as principal the amount of Securities allotted to us by the Manager.

3. Offering Materials. (a) We understand and acknowledge that if registration of the offer and sale of the Securities as contemplated by the Underwriting Agreement is required under the 1933 Act, the Manager will, at our request, furnish to us, as soon as practicable after sufficient quantities thereof are made available to the Manager by the Issuer, copies of the Prospectus (as defined below) (excluding any documents incorporated by reference therein) to be used in connection with the offering of the Securities in such number of copies as we may reasonably request. As used herein, “Prospectus” means the form of prospectus (including any supplements and any documents incorporated by reference therein) authorized for use in connection with the offering of such Securities.

(b) We understand and acknowledge that, if the offer and sale of the Securities are exempt from the registration requirements of the 1933 Act, no registration statement will be filed with the Securities and Exchange Commission (the “Commission”). In such case, the Manager will, at our request, furnish to us, as soon as practicable after sufficient quantities thereof are made available to the Manager by the Issuer, copies, in such number as we may reasonably request of any Offering Circular (as defined below) (excluding any documents incorporated by reference therein) or other offering materials to be used in connection with the offering of the Securities. As used herein, “Offering Circular” means the form of offering circular, offering memorandum or other offering materials (including any supplements and any documents incorporated by reference therein) authorized for use in connection with the offering of such Securities. The Prospectus or Offering Circular, as the case may be, relating to an offering of Securities is herein referred to as the “Offering Document.”

(c) We acknowledge and agree that in purchasing Securities we will rely upon no statement whatsoever, written or oral, other than the statements in the Offering Document delivered to us by the Manager, including any documents incorporated by reference therein. We understand and acknowledge that we are not authorized to give any information or make any representation not contained in the Offering Document, including in any document incorporated by reference therein, in connection with the offering of the Securities. Our purchase of Securities shall constitute our agreement that, if requested by the Manager, we will furnish a copy of any amendment or supplement to any preliminary or final Offering Document to each person to whom we have furnished a previous preliminary or final Offering Document. Our purchase of Securities registered under the 1933 Act or in any other offering to which the provisions of Rule

15c2-8 (or any successor provision) under the Securities Act of 1934, as amended (the “1934 Act”), are made applicable by notice from the Manager to us or otherwise, shall constitute our confirmation that we have delivered, and our agreement that we will deliver, all preliminary and final Prospectuses required for compliance with Rule 15c2-8 (or any successor provision) under the 1934 Act. Our purchase of Securities exempt from registration under the 1933 Act shall constitute our confirmation that we have delivered, and our agreement that we will deliver, all preliminary and final Offering Circulars required for compliance with the applicable Federal and state laws and the applicable rules and regulations of any regulatory body promulgated thereunder governing the use and distribution of offering circulars by underwriters or initial purchasers.

4. Offering of the Securities. (a) The offering of the Securities is made subject to the conditions referred to in the Offering Document and to the terms and conditions set forth in this Agreement. After the public offering of the Securities has commenced, the Manager may change the public offering price, public offering size, the selling concession and the reallowance. Any of the Securities purchased by us pursuant to this Agreement are to be reoffered by us, subject to their receipt and acceptance by the Manager, to investors at the initial public offering price, subject to the terms of this Agreement and the Offering Document. Except as otherwise provided herein, the Securities shall not be offered or sold by us below the initial public offering price before the termination of the effectiveness of this Agreement with respect to the offering of the Securities, except that a reallowance from the initial public offering price of not in excess of the amount set forth in the invitation wire, telex, facsimile or electronic data transmission or other written communication (the “Invitation”) from the Manager inviting us to participate as a Selected Dealer in an offering of Securities pursuant to this Agreement may be allowed to any Selected Dealer that (i) agrees that such amount is to be retained and not reallowed in whole or in part, (ii) makes the representations contained in Section 13, and (iii) unless the Securities are “exempted securities” as defined in Section 3(a)(12) of the 1934 Act or are such other securities as may be sold from time to time by a “bank” as defined in Section 3(a)(6) of the 1934 Act (a “Bank”), is not a Bank.

(b) The Manager as such and, with the Manager’s consent, any Underwriter may purchase Securities from, or sell Securities to, any of the Selected Dealers or any of the Underwriters, and any Selected Dealer may buy Securities from, or sell Securities to, any other Selected Dealer or any Underwriter, at the initial public offering price less all or any part of the concession to Selected Dealers.

(c) If we have received or been credited with the Selected Dealers’ concession as to any Securities purchased by us pursuant to this Agreement which, prior to the later of (i) the termination of the effectiveness of this Agreement with respect to the offering of such Securities and (ii) the covering by the Manager of any short position created by the Manager in connection with the offering of such Securities, the Manager may have purchased or contracted to purchase for the account of any Underwriter (whether such Securities have been sold or loaned by us), then we agree to pay the Manager on demand for the accounts of the several Underwriters an amount equal to the Selected Dealers’ concession and, in addition, the Manager may charge us with any broker’s commission and transfer tax paid in connection with such purchase or contract to purchase. Securities delivered on such repurchases need not be represented by the identical certificates originally purchased. With respect to any such repurchased Securities as to which we

have not yet received or been credited with the Selected Dealers’ concession, we shall be responsible for any such broker’s commission and transfer tax and the Manager shall not be obligated to pay any Selected Dealers’ concession as to such Securities.

(d) No expenses shall be charged to Selected Dealers. A single transfer tax upon the sale of the Securities by the respective Underwriters to us will be paid by such Underwriters when such Securities are delivered to us. However, we shall pay any transfer tax on sales of Securities by us and shall pay our proportionate share of any transfer tax or other tax (other than the single transfer tax described above) in the event that any such tax shall from time to time be assessed against us and other Selected Dealers as a group or otherwise.

5. Stabilization and Over-Allotment. The Manager may, with respect to the offering of the Securities, over-allot, purchase and sell Securities or any other securities that may, in whole or in significant part, determine the value of the Securities for long or short account, on such terms as the Manager may deem advisable, and stabilize or maintain the market price of the Securities. We agree that upon the Manager’s request at any time and from time to time prior to the termination of the effectiveness of this Agreement with respect to an offering of Securities, we will report the amount of Securities purchased by us pursuant to such offering which then remain unsold by us and will, upon the Manager’s request at any such time, sell to the Manager for the account of one or more Underwriters such amount of such unsold Securities as the Manager may designate at the initial public offering price less an amount to be determined by the Manager not in excess of the Selected Dealers’ concession.

6. Compliance with Regulation M.

Unless the Securities are “exempted securities” as defined in Section 3(a)(12) of the 1934 Act, we represent that, at all times since we were invited to participate in the offering of the Securities, we have complied with the provisions of Regulation M applicable to such offering, in each case as interpreted by the Commission and after giving effect to any applicable exemptions. If we have been notified by the Manager that the Underwriters may conduct passive market making in compliance with Rule 103 of Regulation M in connection with the offering of the Securities, we represent that, at all times since our receipt of such notice, we have complied with the provisions of such Rule applicable to such offering, as interpreted by the Commission and after giving effect to any applicable exemptions.

If the Securities are convertible into or exchangeable or exercisable for shares of common stock and such common stock is subject to options traded on a securities exchange, we represent and warrant that we have not, since the day following the date of the Invitation, entered into a discount or parity opening uncovered writing transaction in options to acquire shares of such common stock for our account or for the account of any customer and we agree that we will not enter into any such transaction prior to the termination of the provisions of this Agreement with respect to such offering of Securities. The term “discount or parity opening uncovered writing transaction” means an opening sale transaction where the seller is the writer of an option to purchase shares of such common stock which he does not then own or have the right to acquire upon exercise of conversion option rights, which option is sold at a price (exclusive of commissions) per optioned share which, when added to the amount per share payable upon exercise of the option, shall be equal to or less than the last reported sales price (exclusive of commissions) per share immediately prior to the time such option is sold.

7. Net Capital. We represent and warrant that the incurrence by us of our obligations hereunder in connection with the offering of the Securities will not place us in violation of Rule 15c3-1 under the 1934 Act, if such requirements are applicable to us, or, if we are a financial institution subject to regulation by the Board of Governors of the Federal Reserve System, the Comptroller of the Currency or the Federal Deposit Insurance Corporation, will not place us in violation of the capital requirements of such regulator or any other regulator to which we are subject.

(New York City time) on the date on which the Underwriters are required to purchase the Securities, by delivery to the Manager, at its office, of payment in the manner and type of funds and currency specified in the payment instructions of the Manager given to us, payable to the order of “▇▇▇▇▇ Fargo Securities, LLC” If payment is made for Securities purchased by us at the initial public offering price, the Selected Dealers’ concession to which we may be entitled will be paid to us upon termination of the effectiveness of this Agreement with respect to the offering of such Securities.
