 1. Payment of Exercise Price 
 Prior to or concurrently with the delivery of this Agreement to the Company, Purchaser has delivered the exercise price for the Shares in accordance with the terms of the Plan and the agreement evidencing
the applicable Option (the “Option Agreement”). 
 2. Securities Law Compliance 

2.1 Purchaser represents and warrants that Purchaser (a) has been furnished with a copy of the Plan and all information which
Purchaser deems necessary to evaluate the merits and risks of the purchase of the Shares, (b) has had the opportunity to ask questions and receive answers concerning the information received about the Shares and the Company, and (c) has
been given the opportunity to obtain any additional information Purchaser deems necessary to verify the accuracy of any information obtained concerning the Shares and the Company. 

 2.2 Purchaser hereby confirms that Purchaser has been informed that the Shares have
not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws pursuant to exemptions from registration. Purchaser further confirms that Purchaser understands that the
reliance by the Company on such exemptions is predicated in part on the truth and accuracy of the statements by Purchaser in this Agreement. 
 2.3 Purchaser hereby represents and warrants that Purchaser is purchasing the Shares for Purchaser’s own account, for investment purposes only, and not with a view towards the distribution or
public offering of all or any part of the Shares. 
 2.4 Purchaser hereby confirms that Purchaser understands that
because the Shares have not been registered under the Securities Act, Purchaser must continue to bear the economic risk of the investment for an indefinite period of time and the Shares cannot be sold unless the Shares are subsequently registered or
an exemption from registration is available. 
 2.5 Purchaser hereby agrees that Purchaser will in no event sell or
distribute all or any part of the Shares unless (a) there is an effective registration statement under the Securities Act and applicable state securities laws covering any such transaction involving the Shares or (b) the Company receives
an opinion of Purchaser’s legal counsel (concurred in by legal counsel for the Company) stating that such transaction is exempt from registration or the Company otherwise satisfies itself that such transaction is exempt from registration.

 2.6 Purchaser hereby consents to the placing of a legend on Purchaser’s certificate(s) as set forth in
Section 5 and to the placing of a stop-transfer order on the books of the Company and with any transfer agents against the Shares until the Shares may be legally resold or distributed. 

2.7 Purchaser hereby confirms that Purchaser understands that at the present time Rule 144 of the Securities and Exchange
Commission (the “SEC”) may not be relied on for the resale or distribution of the Shares by Purchaser. Purchaser understands that the Company has no obligation to Purchaser to register the Shares with the SEC and has not
represented to Purchaser that it will so register the Shares. 
 2.8 Purchaser confirms that Purchaser has been advised,
prior to Purchaser’s purchase of the Shares, that neither the offering of the Shares nor any offering materials have been reviewed by any administrator under the Securities Act or any other applicable securities act (the
“Acts”) and that the Shares have not been registered under any of the Acts and therefore cannot be resold unless they are registered under the Acts or unless an exemption from such registration is available. 

 2.9 Purchaser hereby agrees to indemnify the Company and hold it harmless from and
against any loss, claim or liability, including attorneys’ fees or legal expenses, incurred by the Company as a result of any breach by Purchaser of, or any inaccuracy in, any representation, warranty or statement made by Purchaser in this
Agreement or the breach by Purchaser of any terms or conditions of this Agreement. 
 3. Transfer Restrictions 

3.1 Restrictions on Transfer. Shares will not be sold, transferred, assigned, pledged, encumbered or otherwise disposed of in
contravention of the provisions of this Agreement. Except as otherwise provided in this Agreement or in the Option Agreement, such restrictions on transfer, however, will not apply to (a) a gratuitous transfer of the Shares, provided, and only
if, Purchaser obtains the Company’s prior written consent to such transfer, (b) a transfer of title to the Shares effected pursuant to Purchaser’s will or the laws of intestate succession, or (c) a transfer to the Company in
pledge as security for any purchase-money indebtedness incurred by Purchaser in connection with the acquisition of the Shares. 

3.2 Transferee Obligations. Each person (other than the Company) to whom the Shares are transferred by means of one of the
permitted transfers specified in Section 3.1 must, as a condition precedent to the validity of such transfer, acknowledge in writing to the Company that such person is bound by the provisions of this Agreement, to the same extent the Shares
would be so subject if retained by Purchaser. 
 3.3 Market Standoff. In connection with any underwritten public offering
by the Company of its equity securities pursuant to an effective registration statement filed under the Securities Act, including the Company’s initial public offering, Purchaser or any transferee (either being referred to herein as the
“Purchaser”) agrees not to sell, make any short sale of, loan, hypothecate, pledge, assign, grant any option for the purchase of, or otherwise dispose or transfer for value or agree to engage in any of the foregoing
transactions with respect to, any Shares without the prior written consent of the Company or its underwriters. Such limitations will be in effect for such period of time as may be requested by the Company or its underwriters; provided, however, that
in no event will such period exceed 180 days following the effective date of the registration statement. This market standoff provision will be in effect no longer than two years after the effective date of the Company’s initial public
offering. 
 4. Company’s Right of First Refusal 
 Before any Shares held by Purchaser may be sold or otherwise transferred (including any assignment, pledge, encumbrance or other disposition of the Shares, but not including a permitted transfer under
Section 3.1), the Company or its assignee will have an assignable right of first refusal to purchase the Shares on the terms and conditions set forth in this Section 4 (the “Right of First Refusal”). Such Right of
First Refusal shall terminate on the initial registration of the Common Stock under Section 12(b) or 12(g) of the Exchange Act. 

 4.1 In the event Purchaser desires to accept a bona fide third-party offer for the
sale or transfer of any or all of the Shares, Purchaser will promptly deliver to the Company a written notice (the “Notice”) stating the terms and conditions of any proposed sale or transfer, including
(a) Purchaser’s bona fide intention to sell or otherwise transfer such Shares, (b) the name of each proposed purchaser or other transferee (the “Proposed Transferee”), (c) the number of Shares to be
transferred to each Proposed Transferee, and (d) the bona fide cash price or other consideration for which Purchaser proposes to transfer the Shares (the “Offered Price”). Purchaser will provide satisfactory proof that
the disposition of such shares to such Proposed Transferee would not be in contravention of the provisions of Section 3 and Purchaser will offer to sell the Shares at the Offered Price to the Company. 

4.2 At any time within 30 days after receipt of the Notice, the Company or its assignee may, by giving written notice to
Purchaser, elect to purchase all or any portion of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with Section 4.3. 

4.3 The purchase price for the Shares purchased under this Section 4 will be the Offered Price. If the Offered Price includes
consideration other than cash, the cash equivalent value of the noncash consideration will be determined by the Board of Directors of the Company in good faith. 
 4.4 Payment of the purchase price will be made, in the discretion of the Plan Administrator, either (a) in cash (by check), by cancellation of all or a portion of any outstanding indebtedness
of Purchaser to the Company or such assignee, or by any combination thereof, within 30 days after receipt of the Notice or (b) in the manner and at the time(s) set forth in the Notice. 

4.5 If any of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company
and/or its assignee as provided in this Section 4, then Purchaser may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price; provided that such sale or other transfer is consummated within
60 days after the date of the Notice; and provided, further, that any such sale or other transfer is effected in accordance with any applicable securities laws and the Proposed Transferee agrees in writing that the provisions of this
Section 4 will continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, or if Purchaser proposes to change the price or
other terms to make them more favorable to the Proposed Transferee, a new Notice will be given to the Company, and the Company or its assignee will again be offered the Right of First Refusal before any Shares held by Purchaser may be sold or
otherwise transferred. 

 4.6 Notwithstanding any other provision of this Agreement, Purchaser may not deliver
a Notice and the Company may not exercise the Right of First Refusal earlier than six months and one day following the date of this Agreement (or any shorter period determined by the Company to be sufficient to avoid a charge to the Company’s
earnings for financial reporting purposes). 
 5. Legends 
 Purchaser understands and agrees that the Shares are subject to first refusal and/or repurchase rights, as set forth in this Agreement. Purchaser understands that the certificate(s) representing the
Shares will bear legends in substantially the following forms: 
 “The securities represented by this certificate are
subject to certain restrictions on public resale and transfer and first refusal and repurchase rights held by the issuer and/or its assignee(s) and may not be sold, assigned, transferred, encumbered or in any way disposed of except as set forth in a
stock purchase agreement between the issuer and the original purchaser of these shares, a copy of which may be obtained at the principal office of the issuer. Such transfer restrictions and first refusal and/or repurchase rights are binding on
transferees of these shares.” 
 “The securities represented by this certificate have not been registered under
the Securities Act of 1933, as amended (the “Act”), or under applicable state securities laws. These securities are subject to restrictions on transferability and resale and may not be transferred or resold except as permitted under the
Act and applicable state securities laws, pursuant to registration or exemption therefrom. Investors should be aware that they may be required to bear the financial risks of this investment for an indefinite period of time. The issuer of these
securities may require an opinion of counsel in form and substance satisfactory to the issuer to the effect that the proposed transfer or resale is in compliance with the Act and any applicable state securities laws.” 

6. Stop-Transfer Notices 

Purchaser understands and agrees that, in order to ensure compliance with the restrictions referred to in this Agreement, the Company may
issue appropriate “stop-transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. The Company will not be required
to (a) transfer on its books any Shares that have been sold or transferred in violation of the provisions of this Agreement or (b) treat as the owner of the Shares, or otherwise accord voting, dividend or liquidation rights to, any
transferee to whom the Shares have been transferred in contravention of this Agreement. 

 7. Independent Tax Advice 
 Purchaser acknowledges that determining the actual tax consequences to each particular Purchaser of exercising the Option or disposing of the Shares may be complicated. These tax consequences will depend,
in part, on Purchaser’s specific situation and may also depend on the resolution of currently uncertain tax law, and other variables not within the control of the Company. Purchaser is aware that Purchaser should consult a competent and
independent tax advisor for a full understanding of the specific tax consequences to Purchaser prior to exercising the Option or disposing of the Shares. Prior to exercising the Option, Purchaser either has consulted with a competent tax advisor
independent of the Company to obtain tax advice concerning the exercise of the Option in light of Purchaser’s specific situation or has had the opportunity to consult with such a tax advisor but chose not to do so. 

8. Withholding and Disposition of Shares 
 As described in the Option Agreement, Purchaser will make arrangements satisfactory to the Company for the payment of any federal, state, local or foreign withholding tax obligations that arise upon
purchase of the Shares. If Purchaser is exercising an Incentive Stock Option, Purchaser agrees to notify the Company if any Shares are disposed of within one year from the date hereof or two years from the Grant Date. 

9. General Provisions 

9.1 Assignment. The Company may assign its first refusal and/or repurchase rights at any time, whether or not such rights are then
exercisable, to any person or entity selected by the Company’s Board of Directors, including, without limitation, one or more stockholders of the Company. 
 9.2 Notices. Any notice required in connection with (a) the Company’s first refusal and/or repurchase rights or (b) the disposition of any Shares covered thereby will be given in
writing and will be deemed effective upon personal delivery or upon deposit in the U.S. mail, registered or certified, postage prepaid and addressed to the party entitled to such notice at the address indicated in this Agreement or at such
other address as such party may designate by 10 days’ advance written notice under this Section 9.2 to all other parties to this Agreement. 
 9.3 No Waiver. No waiver of any provision of this Agreement will be valid unless in writing and signed by the person against whom such waiver is sought to be enforced, nor will failure to enforce
any right hereunder constitute a continuing waiver of the same or a waiver of any other right hereunder. 

 9.4 Cancellation of Shares. If the Company or its assignees will make available, at
the time and place and in the amount and form provided in this Agreement, the consideration for the Shares to be purchased by the Company pursuant to the exercise of the Company’s first refusal and/or repurchase rights in accordance with the
provisions of this Agreement, then, from and after such time, the person from whom such Shares are to be repurchased will no longer have any rights as a Purchaser of such Shares (other than the right to receive payment of such consideration in
accordance with this Agreement). Such Shares will be deemed purchased in accordance with the applicable provisions of this Agreement and the Company or its assignees will be deemed the owner and Purchaser of such Shares, whether or not the
certificates therefor have been delivered as required by this Agreement. 
 9.5 Purchaser Undertaking. Purchaser hereby
agrees to take whatever additional action and execute whatever additional documents the Company may deem necessary or advisable in order to carry out or effect one or more of the obligations or restrictions imposed on either Purchaser or the Shares
pursuant to the express provisions of this Agreement. 
 9.6 Agreement Is Entire Contract. This Agreement constitutes the
entire contract between the parties hereto with regard to the subject matter hereof. This Agreement is made pursuant to the provisions of the Plan and will in all respects be construed in conformity with the express terms and provisions of the Plan.

 9.7 Successors and Assigns. The provisions of this Agreement will inure to the benefit of, and be binding on, the
Company and its successors and assigns and Purchaser and Purchaser’s legal representatives, heirs, legatees, distributees, assigns and transferees by operation of law, whether or not any such person will have become a party to this Agreement
and agreed in writing to join herein and be bound by the terms and conditions hereof. 
 9.8 No Employment or Service
Contract. Nothing in this Agreement will affect in any manner whatsoever the right or power of the Company, or a Related Company, to terminate Purchaser’s employment or services on behalf of the Company, for any reason, with or without
cause. 
 9.9 Stockholder of Record. Purchaser will be recorded as a stockholder of the Company and will have, subject to
the provisions of this Agreement and the Plan, all the rights of a stockholder with respect to the Shares. 
 9.10
Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original, but which, upon execution, will constitute one and the same instrument. 

9.11 Governing Law. This Agreement will be governed by and construed in accordance with the laws of the State of California.

COMMON STOCK 

UNDERWRITING AGREEMENT 
 Philadelphia, Pennsylvania 
 June 27, 2012 

JANNEY MONTGOMERY SCOTT LLC 
 As Representative
of the Several Underwriters 
     Named in Schedule I hereto 
 c/o Janney Montgomery Scott LLC 
 1801 Market Street 

Philadelphia, PA 19103 
 Ladies and Gentlemen:

 Richard M. Osborne, as Trustee of the Chowder Trust dated February 24, 2012 (the “Selling Shareholder”),
proposes, subject to the terms and conditions stated herein, to sell an aggregate of 700,000 shares (the “Shares”) of common stock, par value $0.15 per share (the “Common Stock”) of Gas Natural Inc., an Ohio corporation (the
“Company”), to the several underwriters named in Schedule I hereto (the “Underwriters”) for whom Janney Montgomery Scott LLC is serving as Representative (the “Representative”). The Common Stock to be sold to the
Underwriters by the Selling Shareholder is referred to herein as the “Firm Shares.” The respective amounts of the Firm Shares to be purchased by the several Underwriters are set forth opposite their names in Schedule I hereto. The Firm
Shares shall be offered to the public at a public offering price of $10.10 per Firm Share (the “Offering Price”). 

In order to cover over-allotments in the sale of the Firm Shares, the Underwriters may, at the Underwriters’ election and subject to
the terms and conditions stated herein, purchase for the Underwriters’ own accounts up to 100,000 additional shares of Common Stock from the Selling Shareholder. Such 100,000 additional shares of Common Stock are referred to herein as the
“Optional Shares.” If any Optional Shares are purchased, the Optional Shares shall be purchased for offering to the public at the Offering Price and in accordance with the terms and conditions set forth herein. The Firm Shares and the
Optional Shares are referred to collectively herein as the “Shares.” 

  
 1 

 In consideration of the mutual agreements contained in this Underwriting Agreement (the
“Agreement”), the Company, the Selling Shareholder and the Underwriters, intending to be legally bound, hereby confirm their agreement as follows: 
 1. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, the Underwriters that: 

(a) The Company has prepared, in accordance with the requirements of the Securities Act of 1933, as amended (the “Act”), and
the rules and regulations (the “Regulations”) of the Securities and Exchange Commission (the “SEC”) thereunder and has filed with the SEC a registration statement on Form S-3 (File No. 333-175683) and one or more amendments
thereto and a prospectus for the purpose of registering the Shares under the Act. The term “Registration Statement” as used herein means the registration statement (including all exhibits and information incorporated by reference therein)
as amended to the date of this Agreement, and includes information (if any) contained in a form of prospectus or prospectus supplement that is deemed retroactively to be part of the Registration Statement, pursuant to Rule 430B under the Act, to be
part of the registration statement as of the time specified in Rule 430B. If it is contemplated, at the time this Agreement is executed, that a post-effective amendment to the Registration Statement will be filed and must be declared effective
before the offering of the Shares may commence, the term “Registration Statement” as used herein shall mean the Registration Statement as amended by such post-effective amendment. If the Company has filed, or files on or after the date of
this Agreement, a registration statement to register Common Stock pursuant to Rule 462(b) under the Act (the “Rule 462(b) Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to
include such Rule 462(b) Registration Statement. The term “Base Prospectus” shall mean the base prospectus filed as part of the Registration Statement in the form in which it has most recently been filed with the SEC on or prior to the
date of this Agreement. The term “Preliminary Prospectus” shall mean any preliminary prospectus supplement relating to the Shares, together with the Base Prospectus, and filed with the SEC pursuant to Rule 424(a) of the Regulations. The
term “Statutory Prospectus” shall mean the Preliminary Prospectus, as amended or supplemented, immediately prior to the Initial Sale Time (as defined below), including any document incorporated by reference therein. The term
“Prospectus” shall mean the final prospectus supplement relating to the Shares, together with the Base Prospectus, including any document incorporated by reference therein, that is first filed pursuant to Rule 424(b) after the effective
time of the Registration Statement (the “Effective Time”). The term “Issuer Free Writing Prospectus” shall have the meaning ascribed to it in Rule 433 of the Regulations relating to the Shares, in the form filed or required to be
filed with the SEC or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g) of the Regulations. The term “Disclosure Package” shall mean (i) the Statutory Prospectus, (ii) the
Issuer Free Writing Prospectus, if any, identified in Schedule II hereto, and (iii) any other free writing prospectus defined in Rule 405 of the Regulations that is required to be filed by the Company with the SEC or retained by the
Company under Rule 433 of the Regulations and that all parties hereto expressly agree to treat as 

  
 2 

 
part of the Disclosure Package (the “Other Free Writing Prospectus”). For purposes of this Agreement, the “Initial Sale Time” shall mean 5:00 p.m. (Eastern Time) on the date
of this Agreement. All references in this Agreement to the Registration Statement, the Rule 462(b) Registration Statement, the Base Prospectus, a Preliminary Prospectus, the Statutory Prospectus, the Prospectus, the Issuer Free Writing Prospectus,
the Other Free Writing Prospectus or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the SEC pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”). 

(b) The Registration Statement has become effective under the Act, and the SEC has not issued any stop order suspending the effectiveness
of the Registration Statement or preventing or suspending the use of the Statutory Prospectus or the Prospectus, nor has the SEC instituted or, to the Company’s knowledge, threatened to institute proceedings with respect to such an order. No
stop order suspending the sale of the Shares in any jurisdiction in which the Underwriter may offer the Shares has been issued, and no proceedings for that purpose have been instituted or, to the Company’s knowledge, threatened. The Company has
complied in all material respects with all requests of the SEC, or requests of which the Company has been advised of any state or foreign securities commission in a state or foreign jurisdiction in which the Underwriter may offer the Shares, for
additional information to be included in the Registration Statement, the Disclosure Package, or the Prospectus. 
 (c) (i) The
Registration Statement complied at the Effective Time and, as amended or supplemented, complies on the date hereof and will comply on the Closing Date (as defined herein) and any Option Closing Date (as defined herein), in all material respects,
with the requirements of the Act and the Regulations, (ii) the Registration Statement, at the Effective Time, did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading, (iii) the Disclosure Package, at the time it was filed and as of the Initial Sale Time, complied in all material respects with the requirements of the Act and the Regulations, (iv) the Disclosure
Package at the time it was filed and as of the Initial Sale Time, did not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they
were made, not misleading, (v) the Prospectus, at the time it is filed and, as amended or supplemented, as of the Closing Date and any Option Closing Date, will comply in all material respects with the requirements of the Act and the
Regulations, (vi) the Prospectus, at the time it is filed and, as amended or supplemented, as of the Closing Date and any Option Closing Date, will not contain any untrue statement of a material fact or omit to state a material fact necessary
to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however that the representations and warranties set forth in this section do not apply to omissions from or statements in
the Registration Statement, the Disclosure Package or the Prospectus based upon and in conformity with written information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and
agreed that the only information furnished by any Underwriter for use in the Registration Statement, the Disclosure Package and the Prospectus is the information as described in Section 14 of this Agreement, and (vii) the statistical and
market related data included or incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus are based on or derived from sources that the Company believes to be reliable and accurate or represent the
Company’s good faith estimate that are made on the basis of data derived from such sources. 

  
 3 

 (d) As of the Initial Sale Time, the Disclosure Package complied in all material respects
with the Act and the Regulations and, if filed by electronic transmission pursuant to EDGAR (except as may be permitted by Regulation S-T under the Act), was identical to the copy thereof delivered to the Underwriters for use in connection with the
offer and sale of the Shares. The Disclosure Package, at the Initial Sale Time, did not, and at the Closing Date will not, contain any untrue statement of a material fact or 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. The preceding sentence does not apply to omissions from or statements in the Disclosure Package based upon and in conformity with written
information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter for use in the Disclosure Package is the
information as described in Section 14 of this Agreement. 
 (e) The Company (including its agents and representatives,
other than the Underwriters in their capacity as such) has not used, authorized, approved or referred to and will not use, authorize, approve or refer to any Issuer Free Writing Prospectus, other than the documents listed on Schedule II
hereto. Each such Issuer Free Writing Prospectus complied when issued in all material respects with the Act and the Regulations and has been filed in accordance with the Act and the Regulations (to the extent required thereby). Each Issuer Free
Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Shares or until any earlier date of which the Company notified or notifies the Representative as described in the next
sentence, did not, does not and will not include any information that, in any material respect, conflicted, conflicts or will conflict with the information contained in the Registration Statement. If at any time following issuance of an Issuer Free
Writing Prospectus, 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 included or 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 prevailing at that subsequent time, not misleading, (i) the Company
has promptly notified or will promptly notify the Representative and (ii) the Company has promptly amended or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or
omission. The foregoing sentences do not apply to conflicts with, omissions from or statements in any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Company by any Underwriter through the
Representative specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representative for use in any Issuer Free Writing Prospectus is the information as set forth in
Section 14 of this Agreement. 
 (f) The Company has not distributed and will not distribute, prior to the later of the
last Option Closing Date (as defined herein) and the completion of the Underwriters’ distribution of the Shares, any offering material in connection with the offering and sale of the Shares other than the Registration Statement, the Disclosure
Package or the Prospectus. 

  
 4 

 (g) The documents incorporated by reference into the Registration Statement, the Disclosure

 (h) There
are no legal or governmental proceedings pending or, to the knowledge of the Company, threatened to which the Company or any of its Subsidiaries (as defined herein) is a party, or to which any of their respective properties or assets are subject,
that are required to be described in the Registration Statement, the Disclosure Package or the Prospectus that are not so described, except for such proceedings that, individually or in the aggregate, would not reasonably be expected to have a
material adverse effect on the general affairs, properties, assets, operations, condition (financial or otherwise), results of operations, shareholders’ equity, or business (collectively, the “Business Conditions”) of the Company and
the Subsidiaries taken as a whole (a “Material Adverse Effect”). There are no statutes or regulations that are required to be described in the Registration Statement, the Disclosure Package or the Prospectus or to be filed as exhibits to
the Registration Statement that are not described or filed as required, except as would not reasonably be expected to have a Material Adverse Effect. References to “material” or “materiality” or “material adverse
change” as applicable to the Company or any of its Subsidiaries shall mean material to the Business Conditions of the Company and the Subsidiaries taken as a whole. 
 (i) The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Ohio, and has all necessary power and authority, to own or lease and operate its
properties and to conduct its current business as described in the Registration Statement, the Disclosure Package and the Prospectus, and to execute, deliver and perform this Agreement. Each of the entities listed on Schedule III hereto,
shall herein be referred to individually as a “Subsidiary” and collectively as the “Subsidiaries.” Each Subsidiary has been duly incorporated or formed and is a corporation or limited liability company validly existing and in
good standing under the laws of the jurisdiction of its incorporation or formation, with all necessary power and authority, corporate and otherwise, and all required licenses, permits, certifications, registrations, approvals, consents and
franchises to own or lease and operate its properties and to conduct its current business as described in the Registration Statement, the Disclosure Package and the Prospectus. The Company and its Subsidiaries are duly qualified to do business as
foreign entities, and are in good standing, in all jurisdictions in which such qualification is required, except where the failure to so qualify or to be in good standing would not have a Material Adverse Effect. 

(j) All of the outstanding shares of capital stock of each of the Subsidiaries have been duly authorized and validly issued, are fully
paid and non-assessable and are owned, directly or indirectly, by the Company, free and clear of all liens, encumbrances and security interests; and no options, warrants or other rights to purchase, agreements or other obligations to issue, or other
rights to convert any obligations into shares of capital stock or ownership interests 

  
 5 

 
in each of the Subsidiaries or securities convertible into or exchangeable for capital stock of, or other ownership interests in any of the Subsidiaries are outstanding except as disclosed in the
Registration Statement, the Disclosure Package or the Prospectus. Except for shares in the Subsidiaries, or except as described in the Registration Statement, the Disclosure Package or the Prospectus, neither the Company nor the Subsidiaries owns
any stock or other interest whatsoever, whether equity or debt, in any corporation, limited liability company, partnership or other entity. 
 (k) This Agreement has been duly authorized, executed and delivered by the Company and constitutes its legal, valid and binding obligation, enforceable against the Company in accordance with its terms,
except as enforcement may be limited by bankruptcy, insolvency or other similar laws relating to or affecting the enforcement of creditors’ rights generally and subject to applicability of general principles of equity and except, as to this
Agreement, as rights to indemnity and contribution may be limited by federal and state securities laws or principles of public policy. 
 (l) The execution, delivery and performance of this Agreement and the transactions contemplated herein, do not and will not, with or without the giving of notice or the lapse of time, or both,
(i) conflict with any term or provision of the Company’s or the Subsidiaries’ respective Certificate or Articles of Incorporation, as the case may be, Code of Regulations or Bylaws, as the case may be, or similar governing documents;
(ii) result in a breach of, constitute a default under, result in the termination or modification of, result in the creation or imposition of any lien, security interest, charge or encumbrance upon any of the properties of the Company or the
Subsidiaries or require any payment by the Company or any of the Subsidiaries or impose any liability on the Company or any of the Subsidiaries pursuant to, any contract, indenture, mortgage, deed of trust, commitment or other agreement or
instrument to which the Company or any of the Subsidiaries is a party or by which any of their respective properties are bound or affected other than this Agreement; (iii) assuming compliance with Blue Sky laws and the rules of the Financial
Industry Regulatory Authority (“FINRA”) applicable to the offer and sale of the Shares, violate any law, rule, regulation, judgment, order or decree of any government or governmental agency, instrumentality or court, domestic or foreign,
having jurisdiction over the Company or the Subsidiaries or any of their respective properties or businesses; or (iv) result in a breach, termination or lapse of the Company’s or the Subsidiaries’ corporate power and authority to own
or lease and operate their respective properties and conduct their respective businesses, except, in the cases of clauses (ii), (iii) and (iv) above, as would not reasonably be expected to have a Material Adverse Effect. 

(m) At the Effective Time and on the Closing Date and any Option Closing Date, there will be no options or warrants or other outstanding
rights to purchase, agreements or obligations to issue or agreements or other rights to convert or exchange any obligation or security into, capital stock of the Company or securities convertible into or exchangeable for capital stock of the
Company, except as disclosed in the Registration Statement, the Disclosure Package and the Prospectus or the grant of options, restricted stock or restricted stock units after the date of the Registration Statement, the Disclosure Package or the
Prospectus under stock incentive plans or other stock plans of the Company and the sale of Common Stock pursuant to the Company’s employee stock purchase plan and its common stock purchase and dividend reinvestment plan. The information in the
Registration Statement, Disclosure Package and the Prospectus insofar as it relates to all outstanding options and restricted stock units and other rights to acquire securities of the Company as of the dates referred to in the Registration
Statement, the Disclosure Package and the Prospectus, is true and correct in all material respects.

 (n) The currently outstanding shares of the Company’s capital stock have been duly
authorized and are validly issued, fully paid and non-assessable, and none of such outstanding shares of the Company’s capital stock has been issued in violation of any preemptive rights or similar rights of any security holder of the Company.
The holders of the outstanding shares of the Company’s capital stock are not subject to personal liability solely by reason of being such holders. All previous offers and sales of the outstanding shares of the Company’s capital stock,
whether described in the Registration Statement, Disclosure Package, the Prospectus or otherwise, were made in conformity with applicable federal, state and foreign securities laws. The authorized capital stock of the Company, including, without
limitation, the outstanding Common Stock and the outstanding options to purchase shares of Common Stock conform in all material respects with the descriptions thereof in the Registration Statement, the Disclosure Package and the Prospectus, and such
descriptions conform in all material respects with the instruments defining the same. The description of the Company’s stock plans, equity compensation plans and other equity arrangements, and the rights granted thereunder, set forth in the
Registration Statement, the Disclosure Package and the Prospectus accurately and fairly presents, in all material respects, the information required to be shown with respect to such plans, arrangements and rights. 

(o) There are no contracts, agreements or understandings between the Company or any of its Subsidiaries and any person granting such
person the right to require the Company to file a registration statement under the Act with respect to any securities of the Company owned or to be owned by such person or to require the Company to include such securities in the securities
registered pursuant to the Registration Statement or in any securities being registered pursuant to any other registration statement filed by the Company under the Act. 
 (p) No consent, approval, authorization, order, registration, license or permit of, or filing or registration with, any court, government, governmental agency, instrumentality or other regulatory body or
official is required for the valid and legal execution, delivery and performance by the Company of this Agreement and the consummation of the transactions contemplated hereby, except (i) such as may be required for the registration of the
Shares under the Act and the listing of the Shares on the NYSE Amex Equities, (ii) filings under the Exchange Act, or (iii) filings required for compliance with the applicable state securities or Blue Sky laws or the bylaws, rules and
other pronouncements of FINRA. 
 (q) The Common Stock is registered pursuant to Section 12(b) of the Exchange Act. The
issued and outstanding shares of Common Stock are listed on the NYSE Amex Equities. Neither the Company nor, to the Company’s knowledge, any other person has taken any action designed to cause, or likely to result in, the termination of the
registration of the Common Stock under the Exchange Act. The Company has not received any notification that the SEC, the NYSE Amex Equities or FINRA is contemplating terminating such registration or inclusion. References to “knowledge” as
applicable to the Company or any of its Subsidiaries shall mean the actual knowledge of the executive officers of the Company or its Subsidiaries who are named in the Prospectus.

 (r) The statements in the Registration Statement, the Disclosure Package and the Prospectus,
insofar as they are descriptions of or references to contracts, agreements or other documents, are accurate in all material respects and present or summarize fairly, in all material respects, the information required to be disclosed under the Act or
the Regulations, and there are no contracts, agreements or other documents, instruments or transactions of any character required to be described or referred to in the Registration Statement, the Disclosure Package or the Prospectus or to be filed
as exhibits to the Registration Statement that have not been so described, referred to or filed, as required.

the business of the Company or the Subsidiaries, has been duly and validly executed by the Company or the Subsidiaries, as applicable and, to the knowledge of the Company, by the other parties thereto. Each such contract or other instrument is in
full force and effect and is enforceable against the parties thereto in accordance with its terms, except (i) as enforcement may be limited by bankruptcy, insolvency or other similar laws affecting the enforcement of creditors’ rights
generally and subject to applicability of general principles of equity or (ii) where such unenforceability or effectiveness would not have a Material Adverse Effect. Neither the Company nor any of the Subsidiaries is, and to the knowledge of
the Company, no other party thereto is, in default under any such contract or other instrument, and no event has occurred that, with the lapse of time or the giving of notice, or both, would constitute a default under any such contract or other
instrument, except where such event or default would not have a Material Adverse Effect. All necessary consents under such contracts or other instruments to the disclosure in the Registration Statement, Disclosure Package and the Prospectus with
respect thereto have been obtained. 
 (t) The consolidated financial statements of the Company (including the notes thereto)
filed as part of, or incorporated by reference in, the Prospectus and the Registration Statement, the Disclosure Package and the Prospectus present fairly, in all material respects, the financial position of the Company as of the respective dates
thereof, and the results of operations and cash flows of the Company for the periods indicated therein, and have been prepared in conformity with generally accepted accounting principles of the United States. The supporting notes included in the

Company’s employee stock option or equity compensation plans or purchases by the Company’s dividend reinvestment plan; or (vii) any change in the indebtedness of the Company or any of the Subsidiaries that is material to the Company
or any Subsidiary. Neither the Company nor any of the Subsidiaries has any contingent liabilities or obligations that are material and that are not expressly disclosed in the Registration Statement, the Disclosure Package and the Prospectus.

 (v) Neither the Company nor, to the Company’s knowledge, any of its officers, directors or affiliates has
(i) taken, nor shall the Company or such persons take, directly or indirectly, any action designed to, or that might be reasonably expected to, cause or result in stabilization or manipulation of the price of Common Stock, or (ii) since

time for the filing thereof and have paid all material taxes shown on such returns or otherwise due and all material assessments received by them to the extent that the same have become due. Neither the Company nor any of the Subsidiaries has
executed or filed with any taxing authority, foreign or domestic, any agreement extending the period for assessment or collection of any income or other tax and none of them is a party to any pending action or proceeding by any foreign or domestic
governmental agency for the assessment or collection of taxes, and no claims for assessment or collection of taxes have been asserted against the Company or any of the Subsidiaries that would have a Material Adverse Effect. 

(x) Each of ParenteBeard LLC and Hein & Associates LLP (i) has given its report on certain financial statements included as
part of or incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus, and (ii) is an independent registered public accounting firm. 

(y) Neither the Company nor any of the Subsidiaries is in violation of, or in default under, any of the terms or provisions of
(i) its Certificate or Articles of Incorporation, as the case may be, or Code of Regulations or Bylaws, as the case may be, or similar governing instruments, (ii) any indenture, mortgage, deed of trust, contract, commitment or other
agreement or instrument to which it is a party or by which it or any of its assets or properties is bound or affected, (iii) any law, rule, regulation, judgment, order or decree of any government or governmental agency, instrumentality or
court, domestic or foreign, having jurisdiction over it or any of its properties or business, or (iv) any license, permit, certification, registration, approval, consent or franchise, except, with respect to clause (ii), (iii) or

 (z) Except as expressly disclosed in the Registration Statement, the Disclosure Package and
the Prospectus, there are no claims, actions, suits, protests, proceedings, arbitrations, investigations or inquiries pending before, or, to the Company’s knowledge, threatened or contemplated by, any governmental agency, instrumentality, court
or tribunal, domestic or foreign, or before any private arbitration tribunal to which the Company or any of the Subsidiaries is or may be made a party that could reasonably be expected to affect the validity of any of the outstanding Common Stock,
or that, if determined adversely to the Company or any of the Subsidiaries would result in a Material Adverse Effect, nor to the Company’s knowledge is there any reasonable basis for any such claim, action, suit, protest, proceeding,
arbitration, investigation or inquiry. There are no outstanding orders, judgments or decrees of any court, governmental agency, instrumentality or other tribunal enjoining the Company or any of the Subsidiaries from, or requiring the Company or any
of the Subsidiaries to take or refrain from taking, any action, or to which the Company or any of the Subsidiaries or their properties, assets or businesses are bound or subject. 

(aa) Each of the Company and the Subsidiaries owns, or possesses adequate rights to use, or can acquire on reasonable terms, all patents,
patent applications, trademarks, trademark registrations, applications for trademark registration, trade names, service marks, licenses, inventions, copyrights, know-how (including any unpatented and/or unpatentable proprietary or confidential

proprietary information necessary for, used in, or proposed to be used in, the conduct of the business of the Company and the Subsidiaries as described in the Registration Statement, the Disclosure Package and the Prospectus (collectively, the
“Intellectual Property”). Except with respect to that certain coexistence agreement previously provided to the Representative, to the Company’s knowledge, neither the Company nor any of the Subsidiaries has infringed, is infringing or
has received any notice of conflict with, the asserted rights of others with respect to the Intellectual Property that if the subject of an unfavorable decision, ruling or finding, could have a Material Adverse Effect, and the Company knows of no
reasonable basis therefor. To the knowledge of the Company, no other parties have infringed upon or are in conflict with any Intellectual Property owned by the Company or its Subsidiaries. Neither the Company nor any of the Subsidiaries is a party
to, or bound by, any agreement pursuant to which royalties, honorariums or fees are payable by the Company or any of the Subsidiaries to any person by reason of the ownership or use of any Intellectual Property, except for software and computer
applications used in the ordinary course of business. 
 (bb) Each of the Company and the Subsidiaries has good and marketable
title to all property described in the Registration Statement, the Disclosure Package and the Prospectus as being owned by it, free and clear of all liens, security interests, charges or encumbrances and the like, except such as are expressly
described or referred to in the Registration Statement, the Disclosure Package and the Prospectus or such that do not have a Material Adverse Effect. Except as otherwise disclosed in the Registration Statement, the Disclosure Package and the
Prospectus, all real and personal property owned and leased by the Company and the Subsidiaries, as described or referred to in the Registration Statement, the Disclosure Package and the Prospectus is held by the Company or the Subsidiaries, as
applicable, under valid and enforceable leases.

 Except as disclosed in the Registration Statement, the Disclosure Package and the
Prospectus, the executive offices and facilities of the Company and the Subsidiaries (the “Premises”), and all operations presently or formerly conducted thereon by the Company or the Subsidiaries or any predecessors thereof, are now and,
since the Company or the Subsidiaries began to use such Premises, always have been and, to the knowledge of the Company prior to when the Company or the Subsidiaries began to use such Premises, always had been, in compliance with all federal, state
and local statutes, ordinances, regulations, rules, standards and requirements of common law concerning or relating to industrial hygiene and the protection of health and the environment (collectively, the “Environmental Laws”), except to
the extent that any failure in such compliance would not have a Material Adverse Effect. To the Company’s knowledge, there are no conditions on, about, beneath or arising from the Premises or in close proximity to the Premises or at any other
location that (i) might give rise to liability, the imposition of a statutory lien upon the Company or any of the Subsidiaries, (ii) require a “Response,” “Removal” or “Remedial Action,” as defined herein,
under any of the Environmental Laws by the Company or any of the Subsidiaries, or (iii) affect the quality of the groundwater withdrawn by the Company, and that would have a Material Adverse Effect, except as described in the Registration
Statement, the Disclosure Package and the Prospectus. Except as expressly described in the Registration Statement, the Disclosure Package and the Prospectus, and except as will not have a Material Adverse Effect, (i) neither the Company nor any
of the Subsidiaries has received notice or has knowledge of any claim, demand, investigation, regulatory action, suit or other action instituted or threatened against the Company or any of the Subsidiaries or any portion of the Premises or any
parcel in close proximity to the Premises relating to any of the Environmental Laws and (ii) neither the Company nor any of the Subsidiaries has received any notice of material violation, citation, complaint, order, directive, request for
information or response thereto, notice letter, demand letter or compliance schedule to or from any governmental or regulatory agency arising out of or in connection with “hazardous substances” (as defined by applicable Environmental Laws)
on, about, beneath, arising from or generated at the Premises, near the Premises or at any other location. As used in this subsection, the terms “Response,” “Removal,” and “Remedial Action” shall have the respective
meanings assigned to such terms under Sections 101(23)-101(25) of the Comprehensive Environmental Response, Compensation and Liability Act, as amended by the Superfund Amendments and Reauthorization Act, 42 U.S.C. 9601(23)-9601(25). 

(cc) Each of the Company and the Subsidiaries believes they are insured with policies in such amounts and with such deductibles and
covering such risks as are generally deemed adequate and customary for their businesses, including, but not limited to, insurance against accidents, third-party injury or general liability and insurance covering certain real and personal property
owned or leased by the Company and each of the Subsidiaries against theft, damage, destruction, acts of vandalism and all other risks customarily insured against. All policies of insurance insuring the Company or any of the Subsidiaries or their
respective businesses, assets, employees, officers and directors are in full force and effect; the Company and the Subsidiaries are in compliance with the terms of such policies and instruments in all material respects; and there are no claims by
the Company or any of the Subsidiaries under any such policy or instrument as to which any insurance company is denying liability or defending under a reservation of rights clause; and, except as set forth in the Registration Statement, the
Disclosure Package and the Prospectus, neither the Company nor any of the Subsidiaries has been refused any insurance coverage sought or applied for. The Company has no reason to 

  
 11 

 
believe that it or any of the Subsidiaries will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from
similar institutions as may be necessary or appropriate to conduct its business as now conducted and at no cost that would not result in a Material Adverse Effect. 
 (dd) Each of the Company and the Subsidiaries maintain effective internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act. 

(ee) Each of the Company and the Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable
assurances that: (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary in order to permit preparation of financial statements in accordance with
the generally accepted accounting principles of the United States and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the
recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. 
 (ff) Except as disclosed in the Registration Statement, the Disclosure Package and the Prospectus or in any document incorporated by reference therein, since the end of the Company’s most recent
audited fiscal year, there has been (i) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and (ii) no change in the Company’s internal control over financial reporting
that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. 
 (gg) The Company is in compliance in all material respects with all currently effective provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated thereunder that are
applicable, or will be applicable as of the Closing Date (as defined herein) and any Option Closing Date (as defined herein), to the Company. 
 (hh) The Company, the Subsidiaries and any Related Employer (which for purposes of this subsection means any entity that, with respect to the Company or any of the Subsidiaries, is a member of a
controlled group of corporations within the meaning of Section 414(b) of the Internal Revenue Code of 1986, as amended (the “Code”), is, individually or collectively, a trade or business under common control within the meaning of

certain pension, retirement, profit-sharing plans, deferred compensation, bonus, or other incentive plans, or medical, vision, dental, or other health plans, or life insurance or disability plans, or any other employee benefit plans, programs,
arrangements, agreements, or understandings (“Plans”), some of which are subject to the Employee Retirement Income Security Act of 1974, as amended and the rules and regulations thereunder (“ERISA”). Any disclosure regarding the
Plans required under the Act or the Exchange Act has been made in the Registration Statement, the Disclosure Package and the Prospectus and the documents incorporated therein. All Plans that are subject to ERISA are in compliance with ERISA, in all
material respects, and, to the extent a Plan is treated by the Company (or, if applicable, by any Subsidiary or Related Employer) as satisfying the 

  
 12 

 
qualification requirements of Section 401(a) of the Code, such Plan is in compliance with the Code in all material respects and is the subject of a current favorable determination letter
from the Internal Revenue Service as to its tax qualification, or such Plan has been submitted to the Internal Revenue Service for an updated determination letter and the Company expects that the Internal Revenue Service will issue a favorable
determination letter with respect to the Plan. Except as disclosed in the Notes to the Consolidated Financial Statements included in the Prospectus, no Plan is an employee pension benefit plan that is subject to Part 3 of Subtitle B of Title I of
ERISA, a defined benefit plan subject to Title IV of ERISA, or a multiemployer plan. Except as disclosed in the Notes to the Consolidated Financial Statements included in the Prospectus, none of the Company, the Subsidiaries or any Related Employer

termination of employment, except as required by Section 4980B of the Code or comparable state law, and except as disclosed in the Registration Statement, the Disclosure Package and the Prospectus. No fiduciary or other party in interest with
respect to any of the Plans has caused any of such Plans to engage in a prohibited transaction as defined in Section 406 of ERISA and Section 4975 of the Code. As used in this subsection, the terms “defined benefit plan,”
“employee benefit plan,” “employee pension benefit plan,” “employee welfare benefit plan,” “fiduciary,” “multiemployer plan” and “party in interest” shall have the respective meanings
assigned to such terms in Section 3 of ERISA. 
 (ii) No labor dispute exists with the Company’s or the
Subsidiaries’ employees, and to the Company’s knowledge, no such labor dispute is threatened. The Company currently has no knowledge of any existing or threatened labor disturbance by the employees of any of the principal suppliers,
contractors or customers of the Company or any of the Subsidiaries that would have a Material Adverse Effect. 
 (jj) Except as
disclosed in the Registration Statement, the Disclosure Package and the Prospectus, there are no contracts, agreements or understandings between the Company and/or any person that would give rise to a valid claim against the Company and/or the
Underwriter for a brokerage commission, finder’s fee or other like payment in connection with the transactions contemplated herein, or in any contracts, agreements, understandings, payments, arrangements or issuances with respect to the Company
or any of its officers, directors, shareholders, employees or affiliates that may affect the Underwriter’s compensation as determined by FINRA. 
 (kk) The Company is not, and after giving effect to the offering and sale of the Shares and the application of the proceeds therefor described in the Registration Statement, the Disclosure Package and the
Prospectus will not be, an “investment company” or an entity “controlled” by an “investment company,” as such terms are defined in the Investment Company Act of 1940, as amended. None of the Subsidiaries is an
“investment company” as defined in the Investment Company Act of 1940, as amended. 
 (ll) (i) The Company and the
Subsidiaries have received all permits, licenses, franchises, authorizations, registrations, qualifications and approvals (collectively, “Permits”) of governmental or regulatory authorities as may be required to own their properties and
conduct their businesses in the manner described in the Registration Statement, the Disclosure Package 

  
 13 

 
and the Prospectus subject to such qualifications as may be set forth in the Registration Statement, the Disclosure Package and the Prospectus, except for failure to so possess would not have a
Material Adverse Effect; (ii) the Company and the Subsidiaries have fulfilled and performed all of their material obligations with respect to such Permits, and no event has occurred which allows or, after notice or lapse of time or both, would
allow revocation or termination thereof or result in any other material impairment of the rights of the holder of any such Permit, subject in each case to such qualifications as may be set forth in the Registration Statement, the Disclosure Package
and the Prospectus and except where such non performance or noncompliance would not have a Material Adverse Effect; and (iii) except as described in the Registration Statement, the Disclosure Package and the Prospectus, such Permits contain no
restrictions that materially affect the ability of the Company or the Subsidiaries to conduct their businesses. 
 (mm) No
statement, representation, warranty or covenant made by the Company or any of the Subsidiaries in this Agreement or in any certificate or document required by this Agreement to be delivered to the Underwriters is, or as of the Closing Date or any
Option Closing Date will be, inaccurate, untrue or incorrect in any material respect. No transaction has occurred or is proposed between or among the Company or any of the Subsidiaries and any of their respective officers, directors or shareholders
or any affiliate of the foregoing that is required to be described in and is not described in the Registration Statement, the Disclosure Package and the Prospectus. 
 (nn) None of the Company, the Subsidiaries, or, to the Company’s knowledge, any officer, director, employee, partner, agent or other person acting on behalf of the Company or the Subsidiaries has,
directly or indirectly, given or agreed to give any money, property or similar benefit or consideration to any customer or supplier (including any employee or agent of any customer or supplier) or official or employee of any agency or
instrumentality of any government (foreign or domestic) or political party or candidate for office (foreign or domestic) or any other person who was, is or in the future may be in a position to affect the Business Conditions of the Company or any of
the Subsidiaries or any actual or proposed business transaction of the Company or any of the Subsidiaries that (i) could subject the Company or any of the Subsidiaries to any liability (including, but not limited to, the payment of monetary
damages) or penalty in any civil, criminal or governmental action or proceeding that would have a Material Adverse Effect or (ii) with respect to the Company, the Subsidiaries or any officer or director thereof, violates any law, rule or
regulation to which the Company or any of the Subsidiaries is subject. 
 (oo) The Company’s board of directors has validly
appointed an audit committee whose composition satisfies the requirements of the Exchange Act, and the rules and regulations of the SEC adopted thereunder as of the Closing Date. The Company’s audit committee has adopted a charter that

and delivery of this Agreement (with such date being used as the determination date for purposes hereof), the Company was not and is not an Ineligible Issuer (as defined in Rule 405 of the Act), without taking into account any determination by the
SEC pursuant to Rule 405 of the Act that it is not necessary that the Company be considered an Ineligible Issuer. 
 (qq) Any
certificate signed by any officer of the Company or any of the Subsidiaries in such capacity and delivered to the Representative or to counsel for the Underwriters pursuant to this Agreement shall be deemed a representation and warranty by the

pending or threatened against or directly affecting the Company or any of the Subsidiaries before or by any federal, state or other commission, board or administrative agency wherein an unfavorable decision, ruling or finding would have a Material
Adverse Effect. 
 (h) The Representative shall have received at the Closing Date and any Option Closing Date certificates of
the Chief Executive Officer and the Chief Financial Officer of the Company dated, as of the date of the Closing Date or Option Closing Date, as the case may be, and addressed to the Representative individually and as representative of the
Underwriters to the effect that (i) the representations and warranties of the Company in this Agreement are true and correct, as if made at and as of the Closing Date or the Option Closing Date, as the case may be, and that the Company has

 (i) At the time this Agreement is executed and at the Closing Date and any Option Closing Date, as the case may be, each of
ParenteBeard LLC and Hein & Associates LLP shall have furnished to the Representative on behalf of the Underwriters, at the request of the Company, letters, dated the respective dates of delivery thereof, and addressed to the Representative
on behalf of the Underwriters, in form and substance reasonably satisfactory to the Representative in all respects (including, without limitation, the non-material nature of the changes or decreases, if any, referred to in clause (iii) below):

  
 26 

 (i) confirming it is an independent certified public accounting firm within the meaning of
the Act and the Regulations, and stating that the section of the Registration Statement under the caption “Experts” is correct insofar as it relates to it; 
 (ii) stating that, in its opinion, the consolidated financial statements, schedules and notes of the Company audited by it and included in the Registration Statement comply as to form in all material
respects with the applicable accounting requirements of the Act and the Regulations; 
 (iii) for ParenteBeard LLC only, stating
that, on the basis of specified procedures, which included a reading of the latest available unaudited interim consolidated financial statements of the Company (with an indication of the date of the latest available unaudited interim financial
statements), a reading of the minutes of the meetings of the shareholders and the Boards of Directors of the Company and the Subsidiaries and the Audit, Corporate Governance and Nominating, and Compensation Committees of such Boards and inquiries to
certain officers and other employees of the Company and the Subsidiaries responsible for operational, financial and accounting matters and other specified procedures and inquiries, nothing has come to their attention that, except as specified in
their letter, would cause them to believe (x) that at a specified date not more than five business days prior to the date of such letter, there was any change in the capital stock or increase in long-term debt of the Company (other than
increases that the Registration Statement disclosed have occurred or may occur), in each case, as compared with the amounts shown in the Company’s December 31, 2011 audited balance sheets or any later dated Company balance sheet included
in the Registration Statement or (y) that for the periods from and including January 1, 2012 to the date of the latest available unaudited financial statements of the Company, if any, there were any decreases, as compared to the
corresponding periods in the prior year, in operating income or total or per share amounts of net income, except in all instances for changes, decreases or increases that the Registration Statement discloses have occurred or may occur. 

(iv) stating that they have compared specific dollar amounts (or percentages derived from such dollar amounts), numbers of shares and
other numerical data and financial information set forth in the Registration Statement that have been reasonably specified by the Representative prior to the date of this Agreement (in each case to the extent that such dollar amounts, percentages
and other information is derived from the general accounting records subject to the internal controls of the Company’s or the Subsidiaries’ accounting systems, or has been derived directly from such accounting records by analysis or
comparison or has been derived from other records and analyses maintained or prepared by the Company or the Subsidiaries) with the results obtained from the application of readings, inquiries and other appropriate procedures set forth in the letter,
and found them to be in agreement. All financial statements and schedules included in material incorporated by reference into the Prospectus shall be deemed included in the Registration Statement for purposes of this subsection. 

(v) provided, that the letter delivered on the Closing Date or the Option Closing Date, as the case may be, shall use a
“cut-off” date no more than five business days prior to such Closing Date or such Option Closing Date, as the case may be. 

  
 27 

 (j) All corporate and other proceedings and other matters incident to the authorization,
form and validity of this Agreement and the form of the Registration Statement and Prospectus and all other legal matters related to this Agreement and the transactions contemplated hereby shall be reasonably satisfactory in all respects to counsel
to the Underwriters. The Company shall have furnished to such counsel all documents and information that they shall have reasonably requested to enable them to pass upon such matters. 

(k) FINRA shall have confirmed that it has not raised any objection with respect to the fairness and reasonableness of the underwriting
terms and arrangements. 
 (l) The Shares shall have been included for listing on the NYSE Amex Equities. 

(m) At the Closing Date and any Option Closing Date, the Representative shall have been furnished such additional documents, information
and certificates as they shall have reasonably requested. 
 All such opinions, certificates, letters and documents shall be in
compliance with the provisions hereof only if they are reasonably satisfactory in form and substance to the Representative and the Underwriters’ counsel. The Company and the Selling Shareholder, respectively, shall furnish the Representative
with such conformed copies of such opinions, certificates, letters and other documents as it shall reasonably request. If any condition to the Underwriters’ obligations hereunder to be fulfilled prior to or at the Closing Date or any Option
Closing Date, as the case may be, is not fulfilled, the Representative on behalf of the Underwriters may terminate this Agreement with respect to the Closing Date or such Option Closing Date, as applicable, or, if it so elects, waive any such
conditions which have not been fulfilled or extend the time for their fulfillment. Any such termination shall be without liability of the Underwriters to the Company and Selling Shareholders. 

10. Indemnification and Contribution. 
 (a) The Company shall indemnify and hold harmless each Underwriter, and each person, if any, who controls each Underwriter within the meaning of the Act and the Exchange Act, against any and all loss,
liability, claim, damage and expense whatsoever, including, but not limited to, any and all reasonable expenses incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever or in
connection with any investigation or inquiry of, or action or proceeding that may be brought against, the respective indemnified parties, arising out of or based upon any breach of the representations and warranties of the Company made in this
Agreement or any untrue statements or alleged untrue statements of material fact contained in the Registration Statement, any Preliminary Prospectus, the Disclosure Package or the Prospectus, any application or other document filed in any
jurisdiction in order to qualify all or any part of the Shares under the securities laws thereof or filed with the SEC or FINRA (in this Section 10 collectively called “application”), or the omission or alleged omission from any of
the foregoing of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they are made, not misleading; provided, however, that the foregoing indemnity shall not apply in
respect of any statement or omission made in reliance upon and in 

  
 28 

 
conformity with written information furnished to the Company by such Underwriter expressly for use in any Preliminary Prospectus, the Registration Statement or Prospectus, or any amendment or
supplement thereto, or in any application or in any communication to the SEC, as the case may be and provided further that the foregoing indemnification with respect to any Preliminary Prospectus shall not inure to the benefit of such Underwriter if
a copy of the Prospectus (as then amended and supplemented) was not sent or given by or on behalf of such Underwriter to the person asserting any losses, claims, damages or liabilities, and if the Prospectus (as amended and supplemented) would have
cured the defect giving rise to such losses, claims, damages or liabilities. The obligations of the Company under this Section 10(a) will be in addition to any liability the Company may otherwise have. The indemnification obligations of the
Company and the Selling Shareholder shall be several and not joint. 
 (b) The Selling Shareholder shall indemnify and hold
harmless each Underwriter, and each person, if any, who controls each Underwriter within the meaning of the Act and the Exchange Act against any and all loss, liability, claim, damage and expense whatsoever, including, but not limited to, any and
all reasonable expenses incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever or in connection with any investigation or inquiry of, or action or proceeding that may be brought
against, the respective indemnified parties, arising out of or based upon any breach of the representations and warranties of the Selling Shareholder made in this Agreement or any untrue statements or alleged untrue statements of material fact
contained in the Registration Statement, any Preliminary Prospectus, the Disclosure Package or the Prospectus, any application or other document filed in any jurisdiction in order to qualify all or any part of the Shares under the securities laws
thereof or filed with the SEC or FINRA (in this Section 10 collectively called “application”), or the omission or alleged omission from any of the foregoing of a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances in which they are made, not misleading, but only with respect to any and all loss, liability, claim, damage or expense resulting from statements or omissions, or alleged statements or omissions, if
any, made in any Preliminary Prospectus, the Disclosure Package, the Registration Statement or the Prospectus or any amendment or supplement thereof or any application or in any communication to the SEC in reliance upon, and in conformity with
written information furnished to each Underwriter by such Selling Shareholder expressly for use in any Preliminary Prospectus, the Disclosure Package, the Registration Statement or the Prospectus or any amendment or supplement thereof, or any
application or in any communication to the SEC, as the case may be and provided further that the foregoing indemnification with respect to any Preliminary Prospectus shall not inure to the benefit of the Underwriter if a copy of the Prospectus (as
then amended and supplemented) was not sent or given by or on behalf of the Underwriter to the person asserting any losses, claims, damages or liabilities, and if the Prospectus (as amended and supplemented) would have cured the defect giving rise
to such losses, claims, damages or liabilities. The obligations of each Selling Shareholder under this Section 10(b) will be in addition to any liability such Selling Shareholder may otherwise have. The indemnification obligations of the
Company and the Selling Shareholder shall be several and not joint. 
 (c) Each Underwriter severally and not jointly shall
indemnify and hold harmless the Company, the Selling Shareholder, each of the directors of the Company, each of the officers of the Company who shall have signed the Registration Statement, and each other

  
 29 

 
person, if any, who controls the Company or the Selling Shareholder within the meaning of the Act and the Exchange Act, to the same extent as the foregoing indemnities from the Company and the
Selling Shareholder to the Underwriters, but only with respect to any and all loss, liability, claim, damage or expense resulting from statements or omissions, or alleged statements or omissions, if any, made in any Preliminary Prospectus, the
Disclosure Package, the Registration Statement or the Prospectus or any amendment or supplement thereof or any application or in any communication to the SEC in reliance upon, and in conformity with written information furnished to the Company and
the Selling Shareholder by any Underwriter through the Representative expressly for use in any Preliminary Prospectus, the Disclosure Package, the Registration Statement or the Prospectus or any amendment or supplement thereof, or any application or
in any communication to the SEC, as the case may be. The obligations of each Underwriter under this Section 10(c) will be in addition to any liability which such Underwriter may otherwise have. 

(d) If any action, inquiry, investigation or proceeding is brought against any person in respect of which indemnification may be sought
pursuant to Section 10(a), (b) or (c) hereof, such person (hereinafter called the “indemnified party”) shall, promptly after notification of, or receipt of service of process for, such action, inquiry, investigation or
proceeding, notify in writing the party or parties against whom indemnification is to be sought (hereinafter called the “indemnifying party”) of the institution of such action, inquiry, investigation or proceeding. The indemnifying party,
upon the request of the indemnified party, shall assume the defense of such action, inquiry, investigation or proceeding, including, without limitation, the employment of counsel (reasonably satisfactory to such indemnified party) and payment of
expenses. No indemnification provided for in this Section 10 shall be available to any indemnified party who shall fail to give such notice if the indemnifying party does not have knowledge of such action, inquiry, investigation or proceeding
to the extent that such indemnifying party has been materially prejudiced by the failure to give such notice, but the omission to so notify the indemnifying party shall not relieve the indemnifying party otherwise than under this Section 10.
Such indemnified party shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless the employment of such counsel shall have been
authorized in writing by the indemnifying party in connection with the defense of such action or if the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, employed counsel reasonably satisfactory to
the indemnified party, to have charge of the defense of such action, inquiry, investigation or proceeding or if such indemnified party or parties shall have been advised by counsel that there may be a conflict between the positions of the
indemnifying party or parties and of the indemnified party or parties or that there may be legal defenses available to such indemnified party or parties different from or in addition to those available to the indemnifying party or parties, in any of
which events the indemnified party or parties shall be entitled to select counsel to conduct the defense to the extent determined by such counsel to be necessary to protect the interests of the indemnified party or parties, and the reasonable fees
and expenses of such counsel shall be borne by the indemnifying party. The indemnifying party shall be responsible for the fees and disbursements of only one such counsel so engaged by the indemnified party or parties as a group. Expenses covered by
the indemnification in this Section 10 shall be paid by the indemnifying party promptly after written request is submitted by the indemnified party. In the event that it is determined that the indemnified party was not entitled to receive
payments for expenses pursuant to this Section 10, the indemnified party shall 

  
 30 

 
return all sums that have been paid pursuant hereto. No indemnifying party shall, without the prior written consent of the indemnified party, 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 includes an unconditional release of such indemnified party from all
liability on any claims that are the subject matter of such action. Anything in this Section 10 to the contrary notwithstanding an indemnifying party shall not be liable for any settlement of a claim affected without its written consent, which
consent shall not be unreasonably withheld. 
 (e) If the indemnification provided for in this Section 10 is unavailable or
insufficient to hold harmless an indemnified party under Section 10(a), (b) or (c) hereof in respect of any losses, liabilities, claims, damages or expenses (or actions, inquiries, investigations or proceedings in respect thereof)
referred to therein, except by reason of the failure to give notice as required in Section 10(d) hereof (provided that the indemnifying party does not have knowledge of the action, inquiry, investigation or proceeding and to the extent such
party has been materially prejudiced by the failure to give such notice), then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, liabilities, claims, damages or expenses (or
actions, inquiries, investigations or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company, the Selling Shareholder, and the Underwriters from the offering of the Shares. If,
however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of the Company, the Selling Shareholder, and the Underwriters in connection with the statements or omissions which resulted in such losses, liabilities, claims or expenses (or
actions, inquiries, investigations or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Shareholder shall be deemed to be equal to the total net
proceeds from the offering (before deducting expenses) received by them, respectively, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover
page of the 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, the Selling Shareholder, or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

The Company, the Selling Shareholder, and the Underwriters agree that it would not be just and equitable if contributions to this
Section 10(e) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 10(e). The amount paid or payable by an
indemnified party as a result of the losses, liabilities, claims, damages or expenses (or actions, inquiries, investigations or proceedings in respect thereof) referred to above in this Section 10(e) shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10(e), (i) no Underwriter shall not be required to
contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter, and (ii) 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. 

  
 31 

 11. Representations and Agreements to Survive Delivery. Except as the
context otherwise requires, all representations, warranties and agreements contained in this Agreement shall be deemed to be representations, warranties and agreements at the Closing Date and any Option Closing Date. All such representations,
warranties and agreements of the Underwriters, the Company, and the Selling Shareholder, including, without limitation, the indemnity and contribution agreements contained in Section 10 hereof and the agreements contained in Sections 8, 11
and 12 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Underwriter or any controlling person, and shall survive delivery of the Shares and termination of this Agreement, whether
before or after the Closing Date or any Option Closing Date. 
 12. Effective Date of This Agreement and
Termination Hereof. 
 (a) This Agreement shall become effective at 10:00 a.m., Cleveland, Ohio time, on the first
business day following the Effective Time or at the time of the public offering by the Underwriters of the Shares, whichever is earlier, except that the provisions of Sections 8, 10, 11 and 12 hereof shall be effective upon execution hereof. The
time of the public offering, for the purpose of this Section 12, shall mean the time when any of the Shares are first released by the Underwriters for offering by dealers. The Representative, the Company and the Selling Shareholder may prevent
the provisions of this Agreement (other than those contained in Section 8, 10, 11 and 12) from becoming effective without liability of any party to any other party, except as noted below, by giving the notice indicated in Section 12(c)
hereof before the time the other provisions of this Agreement become effective. 
 (b) The Representative shall have the right
to terminate this Agreement at any time prior to the Closing Date or any Option Closing Date as provided in Sections 9 and 13 or if any of the following have occurred: (a) since the respective dates as of which information is given in the
Registration Statement and the Prospectus, any material adverse change or any development involving a prospective material adverse change in or affecting the Business Conditions of the Company and the Subsidiaries, whether or not arising in the
ordinary course of business, that would, in the Representative’s reasonable opinion, make the offering or delivery of the Shares impracticable; (b) any outbreak or escalation of hostilities or other national or international calamity or
crisis or change in economic, political or financial market conditions if the effect on the financial markets of the United States of such outbreak, calamity, crisis or change would, in the Representative’s reasonable opinion, make the offering
or delivery of the Shares impracticable; (c) any suspension or limitation of trading generally in securities on the New York Stock Exchange, the NYSE Amex Equities exchange or the NASDAQ Global Market or the over the counter market or any
setting of minimum prices for trading or the promulgation of any federal or state statute, regulation, rule or order of any court or other governmental authority that in the Underwriter’s reasonable opinion materially and adversely affects
trading on such exchange or over the counter market; (d) the enactment, publication, decree or other promulgation of any federal or state statute, regulation, rule or order of any court or other governmental authority which in the
Underwriter’s reasonable opinion materially and adversely 

  
 32 

 
affects or will materially or adversely affect the Business Conditions of the Company and the Subsidiaries taken as a whole; (e) declaration of a banking moratorium by the United States, New
York, Ohio or Pennsylvania authorities; (f) the taking of any action by any federal, state or local government or agency in respect of its monetary or fiscal affairs that in the Representative’s reasonable opinion has a material adverse
effect on the securities markets in the United States; or (g) trading in any securities of the Company shall have been suspended or halted by FINRA or the SEC. 
 (c) If the Company, the Selling Shareholder or the Representative elects to prevent this Agreement from becoming effective or to terminate this Agreement as provided in this Section 12, the
terminating party shall notify all other parties to this Agreement promptly by telephone or facsimile, confirmed by letter or otherwise in writing. 
 13. Default by an Underwriter. 
 (a) If any Underwriter or
Underwriters shall default in its or their obligation to purchase Firm Shares or Optional Shares hereunder, and if the Firm Shares or Optional Shares with respect to which such default relates do not exceed in the aggregate 10% of the number of Firm
Shares or Optional Shares, as the case may be, that all the Underwriters have agreed to purchase on the relevant Closing Date or Option Closing Date, then the Representative may make arrangements satisfactory to the Company and each Selling
Shareholder for the purchase of such Firm Shares or Optional Shares by other persons, including any of the Underwriters, but if no such arrangements are made by the relevant Closing Date or Option Closing Date, such Firm Shares or Optional Shares to
which the default relates shall be purchased by the Representative and any non-defaulting Underwriter in proportion to their respective commitments hereunder (in addition to the number of Firm Shares and Optional Shares they are obligated to
purchase pursuant to Section 3 hereof). 
 (b) If any Underwriter or Underwriters shall default in its or their obligation
to purchase Firm Shares or Optional Shares hereunder, and if such default relates to more than 10% of the Firm Shares or Optional Shares, as the case may be, the Representative may make arrangements for another party or parties (including a
non-defaulting Underwriter) to purchase such Firm Shares or Optional Shares to which such default relates, on the terms contained herein. In the event that the Representative does not arrange for the purchase of the Firm Shares or Optional Shares to
which a default relates as provided in this Section 13, this Agreement may be terminated by the Representative or by the Company or Selling Shareholder without liability on the part of the non-defaulting Underwriters (except as provided in
Section 10 hereof) or the Company (except as provided in Sections 8 and 10 hereof) or the Selling Shareholder (except as provided in Section 10 hereof); provided that if such default occurs with respect to Optional Shares after the Closing
Date, this Agreement will not terminate as to the Firm Shares or any Optional Shares purchased prior to such termination. Nothing herein shall relieve a defaulting Underwriter of its obligations hereunder, including but not limited to its liability,
if any, to the other Underwriters and to the Company or the Selling Shareholder for damages occasioned by its default hereunder. 

  
 33 

 (c) If the Firm Shares or Optional Shares to which the default relates are to be purchased
by the non-defaulting Underwriters, or are to be purchased by another party or parties, the Representative or the Company shall have the right to postpone the Closing Date or any Option Closing Date, as the case may be, for a reasonable period but
not in any event exceeding seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus or in any other documents and arrangements, and the Company agrees to file promptly any
amendment to the Registration Statement or supplement to the Prospectus that in the opinion of counsel for the Underwriters may thereby be made necessary. The terms “Underwriters” and “Underwriter” as used in this Agreement shall
include any party substituted under this Section 13 with like effect as if it had originally been a party to this Agreement with respect to such Firm Shares and/or Optional Shares.

courts in the Borough of Manhattan in each case located in the City of New York, and the parties irrevocably submit to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court, as to
which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by certified mail to such party’s address set forth above shall be effective service of process
for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding brought in any such court that has been brought in an

 24. Sophisticated Parties; No Fiduciary Relationship. Each of the
parties hereto acknowledges that it is a sophisticated business person who was adequately represented by counsel during negotiations regarding the provisions hereof, including, without limitation, the indemnification and contribution provisions of
Section 10, and is fully informed regarding said provisions. Each of the parties hereto further acknowledges that the provisions of Section 10 hereto fairly allocate the risks in light of the ability of the parties to investigate the

Exchange Act. Each of the Company and Selling Shareholder acknowledges and agrees that in connection with all aspects of each transaction contemplated by this Agreement, the Company and the Selling Shareholders, on the one hand, and the
Underwriters, on the other hand, have an arms-length business relationship that creates no fiduciary duty on the part of the Underwriter and all of the parties expressly disclaim any fiduciary relationship.

 LOCK-UP AGREEMENT

Gas Natural Inc.

Janney Montgomery Scott LLC 
 As Representative of 
 the Underwriters to be listed in

 Schedule I to the Underwriting 

Agreement referred to below 
 1801 Market Street 
 Philadelphia, PA 19103 

Ladies and Gentlemen: 
 This Lock-Up Agreement (this “Agreement”) is being delivered to you in connection with the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by Gas
Natural Inc. (the “Company”), Richard M. Osborne, as Trustee of the Chowder Trust, (the “Selling Shareholder”) and Janney Montgomery Scott LLC as representative (the “Representative”) of the several
underwriters named in the Underwriting Agreement (the “Underwriters”) with respect to the public offering of common shares, $0.15 par value, of the Company (the “Common Stock”). The undersigned is a director or
executive officer of the Company. Capitalized terms used herein and not otherwise defined will have the meaning ascribed to them in the Underwriting Agreement. 
 As an inducement to the Underwriters to underwrite the above-mentioned public sale of Common Stock, the undersigned hereby agrees, from the date hereof and for a period of ninety (90) days (the
“Lock-Up Period”) from the date of the final prospectus filed by the Company with the SEC related to the above-mentioned public sale of Common Stock (the “Supplement Date”), not to, directly or indirectly, sell,
offer to sell, contract to sell, assign, transfer, pledge, grant any option for the sale or purchase of, agree to sell, make any short sale or otherwise dispose of (collectively, “Disposition”), any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock beneficially owned by the undersigned now or on the Supplement Date, or with respect to which the undersigned now or on the Supplement Date has the power of Disposition, or
enter into a transaction that could reasonably be expected to have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of Common Stock, whether any
such aforementioned transaction is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, or publicly disclose the intention to make any such Disposition, or to enter into any such transaction, swap, hedge or other
arrangement, without, in each case, the Representative’s prior written consent. 

  
 A-1

 In addition, the undersigned agrees that, without the Representative’s prior written
consent, he or she will not, during the Lock-Up Period, make any demand for, or exercise any right with respect to, the registration of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for shares of Common
Stock. 
 The foregoing obligations of the undersigned shall not apply to (i) bona fide gifts of securities,
(ii) transfers of securities to “affiliates” of the transferor if the transfers do not involve a public distribution or public offering, (iii) the exercise of any option or warrant to acquire Common Stock or settlement of any
restricted stock or restricted stock units, including the delivery of Common Stock to the Company in satisfaction, in whole or part, of an option exercise price, provided that any Common Stock obtained by such exercise or settlement shall remain
subject to this Agreement, (iv) any transfers of Common Stock pursuant to the terms of the Company’s 401(k) plan, or (v) the pledge of Common Stock as collateral against loans by the undersigned (including any extensions or renewals
of any such pledge), provided that in the case of clauses (i), (ii) or (v) (other than in the case of an extension or renewal), prior to the receipt of such Common Stock, the recipient of the Common Stock executes an agreement identical to
this Agreement. The term “affiliate” shall have the meaning given such term in Rule 144 under the Act. The transferor shall notify the Representative in writing prior to engaging in any transaction or taking any other action that is
subject to the terms of this Agreement during the Lock-Up Period. 
 Notwithstanding anything contained herein to the contrary,
if (i) during the last seventeen (17) days of the Lock-Up Period, the Company issues an earnings release or material news or material event relating to the Company occurs; or (ii) prior to the expiration of the Lock-Up Period, the
Company announces that it will release earnings results during the sixteen (16)-day period beginning on the last day of the Lock-Up Period, the restrictions imposed by this Agreement shall continue to apply until the expiration of the eighteen
(18)-day period beginning on the issuance of the earnings release or the occurrence of the materials news or material event. 

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 Agreement. The undersigned also agrees and consents to the entry of stock transfer instructions with the Company’s transfer agent against the transfer of Common Stock or securities
convertible into or exercisable or exchangeable for Common Stock. The undersigned understands that the Company, the Selling Shareholder and the Underwriters are relying upon this Agreement in proceeding toward consummation of the offering. The
undersigned further understands that (except as otherwise provided below) this Agreement is irrevocable and shall be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned. This Agreement shall
lapse and become null and void if the public offering is not consummated on or before December 31, 2012 or if, prior to such date, the Registration Statement is officially withdrawn by the Company or the Representative informs the Company in
writing that the Underwriters do not intend to proceed with the public offering, whichever occurs earliest. This Agreement shall be governed by, and construed in accordance with, the laws of the state of New York.

 EXHIBIT B 

Matters to be Covered in the Opinion of 
 Kohrman Jackson & Krantz PLL 
 Counsel for the Company
and the Selling Shareholder 
 1. The Company is a corporation duly incorporated and validly existing in good standing
under the laws of the State of Ohio with corporate power and authority to own its properties and conduct its business as described in the Registration Statement and Prospectus. 

2. Each of the Subsidiaries is a corporation or limited liability company in good standing under the laws of the state of its
incorporation or organization and has the corporate or limited liability company power and authority to own its properties and conduct its current business. The outstanding shares of capital stock or membership interests of each of the Subsidiaries
are owned by the Company or another Subsidiary; and to our knowledge, the outstanding shares of capital stock and membership interests of each of the Subsidiaries are owned by the Company or another Subsidiary free and clear of all liens,
encumbrances and security interests. To our knowledge, no options, warrants or other rights to purchase any shares of capital stock or membership interests of any of the Subsidiaries are outstanding. 

3. The Company has authorized and outstanding capital stock as set forth under the caption “Description of Capital Stock” in
the Prospectus. The outstanding Shares have been duly authorized and validly issued and are fully paid and non-assessable. All of the Firm Shares and the Optional Shares (together, the “Offering Shares”) conform in all material respects to
the description thereof contained in the Registration Statement, the Disclosure Package and the Prospectus. The Offering Shares have been duly authorized and, when issued and sold by the Company to, and paid for by, the Underwriters in accordance
with the terms of the Agreement, will be validly issued, fully paid and non-assessable; and no preemptive rights of shareholders, by operation of law, arising under the Company’s Articles of Incorporation or the Ohio General Corporation Law
(the “OGCL”) or, to our knowledge, by contract, exists with respect to any of the Offering Shares or the issuance and sale thereof. 
 4. On the Closing Date, the Selling Shareholder will have good and valid title to the Shares to be sold at the Closing Date by the Selling Shareholder, free and clear of all security interests, claims,
liens, equities and other encumbrances except for the rights of RBS Citizens, N.A.. pursuant to that certain Pledge Agreement dated as of June 18, 2010 between RBS Citizens, N.A. and the Selling Shareholder, and the Selling Shareholder will
have full legal right, power and authority, and all authorization and approval required by law, to enter into the Agreement, to perform his obligations thereunder and to sell, assign, transfer and deliver the Shares to be sold by the Selling
Shareholder 
 5. All Shares outstanding are free of (a) any preemptive rights arising under the Company’s Articles of
Incorporation or the OGCL, or (b) to our knowledge, similar rights that entitle or will entitle any person to acquire any Shares upon the issuance thereof by the Company. To our knowledge, neither the filing of the Registration Statement nor
the offering or sale of the Offering Shares as contemplated by the Agreement gives rise to any rights for or relating to the registration of any Shares or other securities of the Company or any of its Subsidiaries. To our knowledge, except as
disclosed in the Prospectus, there are no outstanding options, warrants or other rights to purchase shares of capital stock of the Company. 

  
 B-1

 6. The Registration Statement has become effective under the Act, and to our knowledge, no
stop order proceedings with respect thereto have been instituted or are pending or threatened under the Act. 
 7. The
descriptions in the Registration Statement, the Disclosure Package and the Prospectus of contracts and other documents are accurate in all material respects and fairly present the information required by the Act and the Regulations to be disclosed
with respect to such contracts and other documents. 
 8. The Registration Statement, the Disclosure Package, the Preliminary
Prospectus, the Prospectus and each amendment or supplement thereto and each document incorporated by reference therein, when they were filed with the SEC, complied as to form in all material respects with the requirements of the Act and the
Exchange Act, as applicable, and the applicable rules and regulations thereunder (except that we express no opinion as to the financial statements, schedules, notes, other financial, accounting or statistical data and information about internal
controls over financial reporting included or incorporated by reference therein). 
 9. The statements set forth under the
caption “Description of Capital Stock” in the Prospectus, insofar as such statements constitute a summary of documents referred to therein or matters of law, are accurate summaries in all material respects and fairly present the
information called for with respect to such documents and matters, subject to the qualifications and assumptions stated therein. 
 10. To our knowledge, there are no contracts, licenses, agreements, leases or documents of a character that are required to be filed as exhibits to the Registration Statement, or to be summarized or
described in the Prospectus, which have not been so filed, summarized, or described. 
 11. To our knowledge, there are no legal
proceedings pending or threatened against the Company or any of the Subsidiaries before or by any federal or state governmental or regulatory commission, board, body, authority or agency that are required to be described in the Prospectus and that
are not so described as required. 
 12. The Company has the corporate power and authority to enter into the Agreement and to
perform its obligations thereunder. 
 13. The Agreement has been duly authorized, executed and delivered by the Company and the
Selling Shareholder. We note that the Agreement provides that it is to be governed by and construed in accordance with the substantive law of the State of New York. However, if the Agreement were governed by the law of the State of Ohio, then,
assuming due execution and delivery by the Representative, the Agreement would be a legal, valid and binding obligation of the Company and the Selling Shareholders enforceable against the Company and the Selling Shareholder in accordance with its
terms, except as enforcement may be limited as set forth below in this opinion. The execution and delivery of the Agreement and the consummation of the transactions contemplated thereby: 

  
 B-2

 a. do not and will not or result in a breach of any of the terms or
provisions of, or constitute a default under (nor constitute any event that, with notice, lapse of time, or both, would result in any breach of or default under), the charter documents of any of the Company or the Subsidiaries; 

b. do not and will not or result in a breach of any of the terms or provisions of, or constitute a default under (nor
constitute any event that, with notice, lapse of time, or both, would result in any breach of or default under) agreement or instrument known to us to which the Company or any of the Subsidiaries is a party or by which any of them may be bound or
that is filed as an exhibit (including exhibits incorporated by reference) to the Registration Statement, except for such breaches or defaults that would not result in a Material Adverse Effect; 

c. does not and will not violate any applicable Ohio or federal law, except where such a violation would not result in a
Material Adverse Effect; and 
 d. does not and will not result in the creation or imposition of any lien, charge
or encumbrance upon any property or assets of the Company or any Subsidiary, except for such liens, charges or encumbrances that would not result in a Material Adverse Effect. 
 14. No permit, consent, authorization, approval, registration, qualification or order of or filing with any federal or state governmental or regulatory commission, board, body, authority or agency
(collectively, “Government Licenses”) is required to be obtained or made by the Company and the Selling Shareholder in connection with the issuance and sale of the Offering Shares, and the consummation by the Company and the Selling
Shareholder of the transactions contemplated by the Agreement, other than such as have previously been obtained, including, without limitation, registration of the requisite Offering Shares under the Act; provided, however, that we express no
opinion as to (a) state securities or Blue Sky laws or foreign securities laws of the various jurisdictions in which the Offering Shares are being offered by the Underwriters thereof, and (b) the approval by FINRA of the terms and
conditions of the Agreement. 
 15. The descriptions in the Registration Statement, the Disclosure Package and the Prospectus of
statutes, regulations or legal or governmental proceedings, insofar as they purport to summarize certain of the provisions thereof, are to our knowledge accurate in all material respects and fairly present the information required to be presented by
the Act and the rules and regulations thereunder; provided that we express no opinion as to (a) any statutes or regulations described or contained in the financial statements, including the notes and schedules thereto, or (b) any Blue Sky
laws. 
 16. The Company is not and, after giving effect to the offering and sale of the Offering Shares, will not be, an
“investment company” or an entity “controlled” by an “investment company,” as such terms are defined in the Investment Company Act of 1940, as amended. No Subsidiary is an “investment company,” as such term is
defined in the Investment Company Act of 1940, as amended. 

  
 B-3

 17. The eligibility requirements for the use of Form S-3 set forth in the General
Instructions thereto have been satisfied by the Company. 
 We have participated in conferences with officers and other
representatives of the Company and the Selling Shareholder, representatives of the Company’s independent accountants, representatives of the Underwriters and their counsel, at which conferences the contents of the Registration Statement, the
Disclosure Package and the Prospectus and related matters (but not all of the information incorporated by reference therein) were discussed. Although we are not passing upon and do not assume any responsibility for the accuracy, completeness or
fairness of the statements contained in the Registration Statement, the Disclosure Package or the Prospectus (except as otherwise set forth in this opinion), in the course of such review and discussion, no facts came to the attention of those
lawyers at Kohrman Jackson & Krantz P.L.L. who have participated in the preparation of the Registration Statement, the Disclosure Package and the Prospectus that would lead them to believe that: 

(i) the Registration Statement, including the information deemed to be a part of the Registration Statement as of its
effective date pursuant to Rule 430B promulgated under the Act and all documents incorporated therein by reference, or in any post-effective amendment to such documents, as of its effective date, contained any untrue statement of a material fact or
omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; 
 (ii) the Disclosure Package as of the Initial Sale Time contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading; or 
 (iii) the Prospectus, as of its date and
as of the Closing Date, contained or contains any untrue statement of material fact, or omitted or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which
they were made, not misleading; 
 except that we express no statement or belief with respect to: 

(i) the financial statements, schedules, notes, other financial, accounting or statistical data or information about
internal controls over financial reporting included in, or incorporated by reference into, the Registration Statement or the Prospectus, 
 (ii) the information and data of a financial or accounting nature and oil and gas reserve evaluation data and related data included in the Registration Statement or the Prospectus, or 

(iii) the exhibits to the Registration Statement. 

  
 B-4

 References in the foregoing opinion to our “knowledge” means the actual knowledge,
without any independent inquiry, of those lawyers at Kohrman Jackson & Krantz P.L.L. who have participated in the preparation of the Registration Statement, the Disclosure Package and the Prospectus.
