None of the Company or its Subsidiaries, nor, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or its Subsidiaries, are currently subject to or the target of any sanctions administered or enforced by the Office of Foreign Assets Control of the U.S. Treasury Department, the U.S. Department of State, the United Nations Security Council, the European Union, Her Majesty’s Treasury, or other relevant sanctions authority (collectively, “Sanctions”); and (i) the Company and its Subsidiaries are not located, organized or resident in a country that is the subject of Sanctions (including, without limitation, Cuba, Iran, North Korea, Sudan, and Syria); and (ii) the Company will not directly or indirectly use the proceeds of the offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person, or in any country or territory, that currently is the subject or target of Sanctions or in any other manner that will result in a violation by any person (including any person participating in the transaction whether as an underwriter, advisor, investor or otherwise) of Sanctions. The Company and its Subsidiaries have not knowingly engaged in for the past three years, are not now knowingly engaged in, and will not knowingly engage in, any dealings or transactions with any individual or entity, or in any country or territory, that at the time of the dealing or transaction is or was the subject or target of Sanctions.

3. Purchase, Sale and Delivery of Offered Securities. On the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein, the Company agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Company, at a purchase price of $[•] per share, that number of Firm Securities (rounded up or down, as determined by the Representatives in their discretion, in order to avoid fractions) obtained by multiplying the number of Firm Securities by a fraction the numerator of which is the number of Firm Securities set forth opposite the name of such Underwriter in Schedule A hereto and the denominator of which is the total number of Firm Securities.

The Company will deliver the Firm Securities to or as instructed by the Representatives for the accounts of the several Underwriters in a form reasonably acceptable to the Representatives against payment of the purchase price in Federal (same day) funds by official bank check or checks or wire transfer to an account at a bank acceptable to the Representatives drawn to the order of the Company, at the office of Goodwin Procter LLP, The New York Times Building, 620 Eighth Avenue, New York, New York 10018, at [•] A.M. (Eastern Time), on [•], 2018, or at such other time not later than seven full business days thereafter as the Representatives and the Company determine, such time being herein referred to as the “First Closing Date.” For purposes of Rule 15c6-1 under the Exchange Act, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering. Delivery of the Firm Securities will be made through the facilities of the Depositary Trust Company (the “DTC”) unless the Representatives shall otherwise instruct.

In addition, upon written notice from the Representatives given to the Company from time to time not more than 30 days subsequent to the date of the Final Prospectus (any such notice being an “Option Notice” and such 30 day period being the “Option Period”), the Underwriters may purchase all or less than all of the Optional Securities at the purchase price per share to be paid for the Firm Securities. Such notice shall set forth (i) the aggregate number of shares of Optional Securities to be sold by the Company as to which the Underwriters are exercising the option and (ii) the time, date and place at which the Optional Securities will be delivered (each time for the delivery of and payment for the Optional Securities being herein referred to as an “Optional Closing Date,” which may be the First Closing Date) (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a “Closing Date”). The Company agrees to sell to the Underwriters the number of Optional Securities specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Securities. Such Optional Securities shall be purchased for the account of each Underwriter in the same proportion as the number of Firm Securities set forth opposite such Underwriter’s name bears to the total number of Firm Securities (subject to adjustment by the Representatives to eliminate fractions) and may be purchased by the Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Securities. No Optional Securities shall be sold or delivered

unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised pursuant to an Option Notice from time to time, but only within the Option Period, and to the extent not previously exercised may be surrendered and terminated at any time upon notice by the Representatives to the Company.

Each Optional Closing Date shall be determined by the Representatives but shall be not later than five full business days after an Option Notice is given. The Company will deliver the Optional Securities being purchased on each Optional Closing Date to or as instructed by the Representatives for the accounts of the several Underwriters in a form reasonably acceptable to the Representatives, against payment of the purchase price therefor in Federal (same day) funds by official bank check or checks or wire transfer to an account at a bank specified by the Company drawn to the order of the Company. The delivery of any Optional Securities will be made through the facilities of the DTC unless the Representatives shall otherwise instruct.

4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Offered Securities for sale to the public as set forth in the Final Prospectus.

5. Certain Agreements of the Company. The Company agrees with the several Underwriters that:

(a) Additional Filings. The Company will file the Final Prospectus, in a form approved by the Representatives, with the Commission pursuant to and in accordance with subparagraph (1) (or, if applicable and if consented to by the Representatives, subparagraph (4)) of Rule 424(b) not later than the earlier of (A) the second business day following the execution and delivery of this Agreement or (B) the fifteenth business day after the Effective Time of the Initial Registration Statement. The Company will advise the Representatives promptly of any such filing pursuant to Rule 424(b) and provide to the Representatives copies of such timely filing. If an Additional Registration Statement is necessary to register a portion of the Offered Securities under the Act but the Effective Time thereof has not occurred as of the execution and delivery of this Agreement, the Company will file the additional registration statement or, if filed, will file a post-effective amendment thereto with the Commission pursuant to and in accordance with Rule 462(b) on or prior to 10:00 P.M., New York time, on the date of this Agreement or, if earlier, on or prior to the time the Final Prospectus is finalized and distributed to any Underwriter, or will make such filing at such later date as shall have been consented to by the Representatives.

(b) Filing of Amendments: Response to Commission Requests. The Company will promptly advise the Representatives of any proposal to amend or supplement at any time the Initial Registration Statement, any Additional Registration Statement or any Statutory Prospectus and will not effect such amendment or supplementation to which the Representatives reasonably object; and the Company will also advise the Representatives promptly of (i) the effectiveness of any Additional Registration Statement (if its Effective Time is subsequent to the execution and delivery of this Agreement), (ii) any amendment or supplementation of a Registration Statement or any Statutory Prospectus, (iii) any request by the Commission or its staff for any amendment to any Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iv) the institution by the Commission of any stop order proceedings in respect of a Registration Statement or the threatening of any proceeding for that purpose, and (v) the receipt by

the Company of any notification with respect to the suspension of the qualification of the Offered Securities in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Company will use its reasonable best efforts to promptly obtain the withdrawal of any such stop order or the suspension of any such qualification.

(c) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by any Underwriter or dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Company will notify the Representatives of such event and, upon their reasonable request, will prepare and file with the Commission and furnish, at its own expense, to the Underwriters, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Representatives’ consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

(d) Rule 158. As soon as practicable, but not later than the Availability Date (as defined below), the Company will make generally available to its security holders an earnings statement covering a period of at least 12 months beginning after the Effective Date of the Initial Registration Statement (or, if later, the Effective Time of the Additional Registration Statement), which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act. For the purpose of the preceding sentence, “Availability Date” means the day after the end of the fourth fiscal quarter following the fiscal quarter that includes such Effective Time on which the Company is required to file its Form 10-Q for such fiscal quarter except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” means the day after the end of such fourth fiscal quarter on which the Company is required to file its Form 10-K.

(e) Furnishing of Prospectuses. The Company will furnish, upon request of the Representatives, to the Representatives copies of each Registration Statement (three of which will be signed and will include all exhibits), each related Statutory Prospectus, and, so long as a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act, the Final Prospectus and all amendments and supplements to such documents, in each case in such quantities as the Representatives request. The Final Prospectus shall be so furnished within two business days following the execution and delivery of this agreement, unless otherwise agreed by the Company and the Representatives. All other such documents shall be so furnished as soon as available, unless otherwise agreed by the Company and the Representatives.

(f) Blue Sky Qualifications. The Company shall reasonably cooperate with the Underwriters and counsel for the Underwriters to qualify or register the Offered Securities for resale under (or obtain exemptions from the application of) the state securities or Blue Sky laws of those jurisdictions designated by the Underwriters, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Offered Securities. Notwithstanding the foregoing, the Company shall not be required to qualify as a foreign corporation or to take any action that would subject it to general service of process or taxation in any such jurisdiction in which it would not otherwise be subject to qualification or taxation.

(g) Reporting Requirements. During the period of five years hereafter, the Company will furnish to the Representatives and, upon request of the Representatives, to each of the other Underwriters, as soon as practicable after the end of each fiscal year, a copy of its annual report to stockholders for such year; and the Company will furnish to the Representatives (i) as soon as available, upon request, a copy of each report and any definitive proxy statement of the Company filed with the Commission under the Exchange Act or mailed to stockholders, and (ii) from time to time, such other information concerning the Company as the Representatives may reasonably request. However, so long as the Company is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”), it is not required to furnish such reports or statements to the Underwriters.

(h) Payment of Expenses. The Company agrees with the several Underwriters that the Company will pay all expenses incident to the performance of the obligations of the Company under this Agreement, including but not limited to, (i) any filing fees and reasonable attorneys’ fees and expenses incurred by the Company or the Underwriters in connection with qualifying or registering (or obtaining exemptions from the qualification or registration of) all or any part of the Offered Securities for offer and sale under the state securities or Blue Sky laws of such jurisdictions as the Representatives reasonably designate and the preparation and printing of memoranda relating thereto, (ii) the filing fees incident to, and the reasonable fees and expenses of counsel for the Underwriters up to $25,000, in connection with the FINRA’s review and approval of the Underwriters’ participation in the offering and distribution of the Offered Securities, (iii) fees and expenses incident to listing the Offered Securities on the NYSE American, (iv) fees and expenses in connection with the registration of the Offered Securities under the Exchange Act, (v) expenses incurred in distributing preliminary prospectuses, the Final Prospectus (including any amendments and supplements thereto) and the Registration Statement (and exhibits thereto) to the Underwriters and expenses incurred for preparing, printing and distributing any Issuer Free Writing Prospectuses to investors or prospective investors, (vi) the reasonable, out-of-pocket fees and expenses of the QIU, acting in its capacity as such, up to $25,000 and (vii) all other fees, costs and expenses referred to in Item 13 of Part II of the Registration Statement. The Company will also pay or reimburse the Underwriters (to the extent incurred by them) for costs and expenses of the Company and its officers and employees and any other expenses of the Company and its officers and employees relating to investor presentations or any “road show” in connection with the offering and sale of the Offered Securities including, without limitation, any travel expenses of the Company’s officers and employees and any other expenses of the Company and its officers and employees, including 50% of the cost of the chartering of airplanes or other transportation. It is understood, however, that except as provided in this Section 5(h) and Sections 8 and 10 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel and any road show expenses incurred by them (other than costs and expenses incurred by the Underwriters on behalf of the Company and its officers and employees).

(i) Use of Proceeds. The Company will use the net proceeds received by it in connection with this offering in the manner described in the “Use of Proceeds” section of the General Disclosure Package and the Final Prospectus.

(j) Absence of Manipulation. The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Offered Securities.

(k) Restriction on Sale of Securities by the Company. For the period specified below (the “Lock-Up Period”), the Company will not, directly or indirectly, take any of the following actions with respect to its Common Stock or any securities convertible into or exchangeable or exercisable for any of its Common Stock (“Lock-Up Securities”): (i) offer, sell, issue, contract to sell, pledge or otherwise dispose of Lock-Up Securities (other than the Offered Securities and shares issued pursuant to employee benefit plans, qualified stock option plans or other employee compensation plans existing on the date hereof and described in the Preliminary Prospectus or the General Disclosure Package), (ii) offer, sell, issue, contract to sell, contract to purchase or grant any option, right or warrant to purchase Lock-Up Securities (other than the grant of options pursuant to employee benefit plans, option plans, qualified stock option plans or other employee compensation plans existing on the date hereof and described in the Preliminary Prospectus or the General Disclosure Package), (iii) enter into any swap, hedge or any other agreement that transfers, in whole or in part, the economic consequences of ownership of Lock-Up Securities, (iv) establish or increase a put equivalent position or liquidate or decrease a call equivalent position in Lock-Up Securities within the meaning of Section 16 of the Exchange Act or (v) file with the Commission a registration statement under the Act relating to Lock-Up Securities, or publicly disclose the intention to take any such action, without the prior written consent of the Representatives, except (i) issuances of Lock-Up Securities pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options, in each case outstanding on the date hereof, and (ii) the filing of a registration statement on Form S-8 relating to, and the issuance and sale of Lock-Up Securities pursuant to, the terms of a plan described in the General Disclosure Package and the Final Prospectus. The initial Lock-Up Period will commence on the date hereof and continue for 180 days after the date hereof or such earlier date that the Representatives consent to in writing.

If the Representatives, in their sole discretion, agree to release or waive the restrictions set forth in a lock-up letter described in Section 5(k) hereof for an officer or director of the Company and provides the Company with notice of the impending release or waiver at least three business days before the effective date of the release or waiver, the Company agrees to announce the impending release or waiver by a press release substantially in the form of Exhibit A hereto through a major news service at least two business days before the effective date of the release or waiver

6. Free Writing Prospectuses. The Company represents and agrees that, unless it obtains the prior consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representatives is hereinafter referred to as a “Permitted Free Writing

Prospectus.” The Company and the Representatives agree that any such Permitted Free Writing Prospectus is listed on Schedule B hereto. The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping. The Company represents that it has satisfied and agrees that it will satisfy the conditions in Rule 433 to avoid a requirement to file with the Commission any electronic road show. If at any time following issuance of an Issuer Free Writing Prospectus, at a time when a prospectus relating to the Offered Securities is (or but for the exemption of Rule 172 would be) required to be delivered under the Act by any Underwriter or dealer, there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information then contained in the Registration Statement or as a result of which such Issuer Free Writing Prospectus, if republished immediately following such event or development, would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

The Representatives shall have received a certificate, dated such Closing Date, of an executive officer of the Company and a principal financial or accounting officer of the Company in which such officers shall state that: the representations and warranties of the Company in this Agreement are true and correct; the Company has completed the Corporate Conversion (i) in accordance with the applicable provisions of Delaware law and (ii) as set forth in the Registration Statement, the General Disclosure Package and the Final Prospectus under the heading “Corporate Conversion”; the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to such Closing Date; no stop order suspending the effectiveness of any Registration Statement has been issued and no proceedings for that purpose have been instituted or, to their knowledge, are contemplated by the Commission; and they have examined the General Disclosure Package and the Final Prospectus, and, to their knowledge, (A) (1) the General Disclosure Package, as of the Applicable Time, and (2) the Final Prospectus, as of its date, did not and do not contain any untrue statement of a material fact and did not and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the light of the circumstances under which they were made) not misleading, and (B) since the Effective Date, no event has occurred that should have been set forth in a supplement or amendment to the Final Prospectus or any Issuer Free Writing Prospectus that has not been so set forth.

The Representatives may in their sole discretion waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder, whether in respect of an Optional Closing Date or otherwise.

8. Indemnification and Contribution.

(a) Indemnification of Underwriters by Company. The Company will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation

or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of any Registration Statement, any Statutory Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other out-of-pocket expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

(b) Indemnification of Company. Each Underwriter will severally and not jointly indemnify and hold harmless the Company, each of its directors (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and each of its officers who signs a Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Underwriter Indemnified Party”), against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, or other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement at any time, any Statutory Prospectus at any time, the Final Prospectus or any Issuer Free Writing Prospectus or in any amendment or supplement thereto or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other out-of-pocket expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information under the caption “Underwriting (Conflicts of Interest)” in the Final Prospectus furnished on behalf of each Underwriter: (i) the concession figure appearing in the third paragraph and (ii) the paragraphs under the heading “Stabilization, Short Positions and Penalty Bids.”

(c) Indemnification of the QIU. Without limitation and in addition to its obligation under the other subsections or Sections of this Section 8, the Company agrees to indemnify and hold harmless the QIU, its officers, employees and agents, and each person, if any, who controls the QIU within the meaning of Section 15 of the Act and of Section 20 of the Exchange Act (each, a “QIU Indemnified Party”), from and against any and all losses, claims, damages, liabilities and/or judgments, as incurred (or action in respect thereof) arising out of or based upon the QIU’s acting (or alleged failure to act) as a “qualified independent underwriter” (within the meaning of Rule 5121(f)(12) of FINRA) in connection with the offering contemplated by this Agreement, and the Company further agrees to reimburse each such QIU Indemnified Party for any legal or other out-of-pocket expense (including, without limitation, the fees and disbursements of special counsel to the QIU) reasonably incurred by thereby in connection with investigating, defending against, settling, compromising or paying any such loss, claim, damage, liability, action, litigation, judgment, investigation or proceeding whatsoever (or action in respect thereof, whether or not the QIU is a party thereto), and whether threatened or commenced, and in connection with the enforcement of this Section 8(c) with respect to any of the above as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability, action, litigation, judgment, investigation or proceeding (or action in respect thereof) results from the gross negligence or willful misconduct of the QIU. If the indemnification provided for in this Section 8(c) is unavailable or insufficient to hold harmless any QIU Indemnified Party in respect of losses, claims, damages, liabilities, actions, litigation, judgments, investigations and/or proceedings (or actions in respect thereof) referred to in the prior sentence, then the Company shall contribute to the amount paid or payable by such QIU Indemnified Party as a result of such losses, claims, damages, liabilities, actions, litigation, judgments, investigations and/or proceedings (or actions in respect thereof), based on the factors described in Section 8(e) of this Agreement; provided, however, that (i) the relative benefits received by the QIU in connection with the offering contemplated by this Agreement shall, for purposes of Section 8(e), be deemed to be equal to the compensation, if any, received by the QIU solely for acting in the capacity of “qualified independent underwriter,” and (ii) notwithstanding the provisions of Section 8(e), the QIU shall not be required to contribute any amount in excess of the compensation, if any, received by the QIU solely for acting in the capacity of “qualified independent underwriter.”

(d) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under subsection (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a), (b) or (c) above. In case any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other out-of-pocket expenses subsequently incurred by such indemnified party in connection with the defense thereof

other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(e) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters as set forth in the table on the cover page of the Final Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other out-of-pocket expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Offered Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8(e).

9. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on either the First Closing Date or any Optional Closing Date and the aggregate number of shares of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date, the Representatives may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of shares of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to the Representatives and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 10 hereof (provided that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the QIU, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 hereof or the occurrence of any event specified in Section 7(d) hereof (other than the occurrence of an event described in Section 7(d)(v)) hereof, the Company will reimburse the Underwriters for all out-of-pocket expenses (including reasonable documented fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities, and the respective obligations of the Company and the Underwriters pursuant to Section 8 hereof shall remain in effect. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 hereof and all obligations under Section 5 hereof shall also remain in effect.

11. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, hand delivered or telecopied and confirmed to the Representatives c/o SunTrust Robinson Humphrey, Inc., 3333 Peachtree Road NE, Atlanta, Georgia 30326, Attention: Equity Capital Origination, and c/o Seaport Global Securities LLC, 360 Madison Avenue, 21st Floor, New York, New York 10017, Attention: Equity Capital Markets, with copies to Goodwin Procter LLP, The New York Times Building, 620 Eighth Avenue, New York, New York 10018, Attention: Thomas S.

Reno Avenue, Suite 500 Oklahoma City, Oklahoma 73104, Attention: Chief Financial Officer, with copies to di Santo Law PLLC, 205 Hudson Street, 7th Floor, New York, New York 10013, Attention: Beth A. di Santo.

12. Parties Entitled to Benefits of Agreement. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective representatives, agents and successors and the officers and directors and controlling persons referred to in Section 7 and Section 8 hereof, and no other person will have any right or obligation hereunder.

13. Representation of Underwriters. The Representatives will act for the several Underwriters in connection with the transactions contemplated by this Agreement, and any action under this Agreement taken by the Representatives jointly will be binding upon all the Underwriters.

14. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

15. Absence of Fiduciary Relationship. The Company acknowledges and agrees that:

(a) No Other Relationship. The Representatives have been retained solely to act as underwriters in connection with the sale of the Offered Securities and that no fiduciary, advisory or agency relationship between the Company, on the one hand, and the Representatives, on the other, has been created in respect of any of the transactions contemplated by this Agreement or the Final Prospectus, irrespective of whether the Representatives have advised or are advising the Company on other matters;

(b) Arms’ Length Negotiations. The price of the Offered Securities set forth in this Agreement was established by Company following discussions and arms-length negotiations with the Representatives, and the Company is capable of evaluating and understanding and understand and accepts the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) Absence of Obligation to Disclose. The Company has been advised that the Representatives and its affiliates are engaged in a broad range of transactions, which may involve interests that differ from those of the Company and that the Representatives have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

(d) Waiver. The Company waives, to the fullest extent permitted by law, any claims they may have against the Representatives for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Representatives shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

16. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

The Company hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Company irrevocably and unconditionally waives any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in the City of New York and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

17. Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the “Representatives”), and certain other firms (the “Underwriters”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by the Underwriters of shares (the “Shares”) of common stock, par value $0.01 per share (the “Common Stock”), of Riley Exploration Permian, Inc., a Delaware corporation (including Riley Exploration—Permian, LLC, a Delaware limited liability company, its predecessor prior to the corporate conversion, the “Company”), and that the Underwriters propose to reoffer the Shares to the public (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of the Representatives, on behalf of the Underwriters, the undersigned will not, directly or indirectly, (1) offer for sale, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of), directly or indirectly, any units, membership interests or shares of Common Stock (including, without limitation, units, membership interests or shares of Common Stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities Exchange Act of 1934 (the “Exchange Act”), as amended, and units, membership interests or shares of Common Stock that may be issued upon exercise of any options or warrants) (collectively, “Company Securities”) or securities convertible into or exercisable or exchangeable for Company Securities, except as set forth in the paragraph below, (2) enter into any swap, hedge or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of Company Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Company Securities or other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any Company Securities or securities convertible into or exercisable or exchangeable for Company Securities or any other securities of the Company, except the filing of a registration statement on Form S-8

relating to, and the issuance and sale of Common Stock pursuant to, the terms of a long term incentive plan described in the Preliminary Prospectus or Final Prospectus (as defined in the Underwriting Agreement), (4) establish or increase a put equivalent position or liquidate or decrease a call equivalent position in securities of the Company or (5) publicly disclose the intention to do any of the foregoing, for a period commencing on the date of the Final Prospectus relating to the Offering and ending on the 180th day thereafter (such 180-day period, the “Lock-Up Period”).

The foregoing paragraph shall not apply to (i) the conversion of Common Units or Series A Preferred Units of the Company into Company Securities in connection with the Corporate Conversion as described in the Final Prospectus or (ii) any Company Securities and any securities convertible into, or exercisable or exchangeable for, Company Securities:

(a)

issued or to be issued pursuant to employee benefit plans, qualified stock option plans or other employee compensation plans existing on or before the date hereof or as described in the Preliminary Prospectus or Final Prospectus, provided that such Company Securities received upon exercise of options granted to the undersigned will also be subject to this Lock-Up Agreement;

(b)

acquired in the open market after the closing of the Offering;

(c)

transferred by the undersigned to the undersigned’s affiliates or any investment fund or other entity controlled or managed by the undersigned, provided that the transferee agrees to be bound in writing by the terms of this Lock-Up Agreement prior to such transfer and such transfer shall not involve a disposition for value;

(d)

transferred through a distribution to limited partners or stockholders of the undersigned, provided that the transferee agrees to be bound in writing by the terms of this Lock-Up Agreement prior to such transfer and such transfer shall not involve a disposition for value;

(e)

transferred by the undersigned for financial and estate planning purposes to family members, immediate family members or trusts, partnerships or similar entities, provided that the transferee agrees to be bound in writing by the terms of this Lock-Up Agreement prior to such transfer and such transfer shall not involve a disposition for value; and

(f)

subject to the establishment of any written contract, instruction or plan that satisfies all of the requirements of Rule 10b5-1 (a “Rule 10b5-1 Plan”) under the Exchange Act; provided, however, that no sales of Company Securities or securities convertible into, or exchangeable or exercisable for, Company Securities, shall be made pursuant to a Rule 10b5-1 Plan prior to the expiration of the Lock-Up Period; and provided further, that no party is required to publicly announce, file, or report the establishment of such Rule 10b5-1 Plan in any public report, announcement, or filing with the Commission under the Exchange Act during the Lock-Up Period and does not otherwise voluntarily effect any such public report, announcement, or filing regarding such Rule 10b5-1 Plan.

In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

If the undersigned is an officer or director of the Company, (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of Company Securities, the Representatives will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this Lock-Up Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

It is understood that (i) if the Company, in its sole and absolute discretion, notifies the Underwriters that it does not intend to proceed with the Offering at any time after the date hereof, (ii) if the Underwriting Agreement does not become effective, or (iii) if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares, the undersigned will be released from its obligations under this Lock-Up Agreement.

The undersigned understands that the Company and the Underwriters will proceed towards consummation of the Offering in reliance on this Lock-Up Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

[Signature page follows]

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

Very truly yours,
