2.            Exercise.

 

2.1          Exercise
Form. In order to exercise this Purchase Warrant, the exercise form attached hereto must be duly executed and completed and
delivered to the Company, together with this Purchase Warrant and payment of the Exercise Price for the Units being purchased payable
in cash by wire transfer of immediately available funds to an account designated by the Company or by certified check or official
bank check. In the event of a partial exercise or assignment hereof, the Company shall issue and deliver to or upon the order of
the Holder a new Purchase Warrant of like tenor, in the name of the Holder or as the Holder (upon payment by the Holder of applicable
transfer taxes) may request, evidencing the right to purchase the aggregate number of Units for which such Purchase Warrant may
still be exercised. If the subscription rights represented hereby shall not be exercised at or before 5:00 p.m., Eastern time,
on the Expiration Date, this Purchase Warrant shall become and be void without further force or effect, and all rights represented
hereby shall cease and expire.

 

2.2          Cashless
Exercise.  If at any time after the Commencement Date there is no effective registration statement registering, or no
current prospectus available for, the resale of the shares of Common Stock, Warrants underlying the Purchase Warrants and shares
of Common Stock underlying the Warrants issuable hereunder by the Holder, then in lieu of exercising this Purchase Warrant by payment
of cash or check payable to the order of the Company pursuant to Section 2.1 above, Holder may elect to receive the number shares
of Common Stock and Warrants equal to the value of this Purchase Warrant (or the portion thereof being exercised), by surrender
of this Purchase Warrant to the Company, together with the exercise form attached hereto, in which event the Company shall issue
to Holder shares of Common Stock in accordance with the following formula:

 

	X	=	
          Y(A-B)  

        A
	 

 

Where,

X=The number of shares of Common Stock to be
issued to Holder;

Y=The number of Units for which the Purchase Warrant
is being exercised;

A=The fair market value of one share of Common
Stock; and

B=The Exercise Price.

 

The number Warrants
to purchase Common Stock issuable upon cashless exercise will be equal to the number of shares of Common Stock issuable in accordance
with the above formula.

 

For purposes of this
Section 2.2, the fair market value of a share of Common Stock is defined as follows:

 

	 	(i)	if the Company’s Common Stock is traded on a
    securities exchange, the value shall be deemed to be the closing price on such exchange as of the trading day immediately
    prior to the      day
    of which the exercise form     being     submitted in connection with the exercise of the Purchase Warrant;
    or

 

	 	(ii)	if the Company’s Common Stock is actively traded
    over-the-counter, the value shall be deemed to be the closing bid price as of the trading day immediately prior to the day
    of which the exercise form being submitted in connection with the exercise of the Purchase Warrant; if there is no active
    public     market,     the value shall be the fair market value thereof, as determined in good faith by the Company’s
    Board of     Directors.

 

2.3         Delivery
of Shares and Warrants. Upon exercise, the applicable number of shares of Common Stock and Warrants shall be delivered to the
Holder within three (3) business days of the Company’s receipt of the exercise form completed and payment of the applicable
Exercise Price, if paid in cash.

 

2.4          Legend.
Each certificate representing the shares of Common Stock and Warrants issued hereunder shall bear a legend as follows unless
such securities have been registered under the Securities Act of 1933, as amended (the “Act”):

 

“The securities
represented by this certificate have not been registered under the Securities Act of 1933, as amended (the “Securities
Act”), or applicable state law. Neither the securities nor any interest therein may be offered for sale, sold or otherwise
transferred except pursuant to an effective registration statement under the Securities Act, or pursuant to an exemption from registration
under the Securities Act and applicable state law which, in the opinion of counsel to the Company, is available.”

3.            Transfer.

 

3.1          General
Restrictions. The registered Holder of this Purchase Warrant agrees by his, her or its acceptance hereof, that such Holder
will not: (a) sell, transfer, assign, pledge or hypothecate this Purchase Warrant for a period of one hundred eighty (180) days
following the Effective Date to anyone other than: (i) Northland Securities, Inc. (“Northland”), Neidiger, Tucker,
Bruner, Inc. (“Neidiger”) or an underwriter or a selected dealer participating in the offering contemplated
by the Underwriting Agreement (the “Offering”), or (ii) a bona fide officer or partner of Northland, Neidiger
or of any such underwriter or selected dealer, in each case in accordance with FINRA Rules 5110(g)(1) and 5110(g)(2)(A)(ii), or
(b) cause this Purchase Warrant or the securities issuable hereunder to be the subject of any hedging, short sale, derivative,
put or call transaction that would result in the effective economic disposition of this Purchase Warrant or the securities hereunder,
except as provided for in FINRA Rule 5110(g)(2). On and after 180 days after the Effective Date, transfers to others may be made
subject to compliance with or exemptions from applicable securities laws. In order to make any permitted assignment, the Holder
must deliver to the Company the assignment form attached hereto duly executed and completed, together with the Purchase Warrant
and payment of all transfer taxes, if any, payable in connection therewith. The Company shall within three (3) business days transfer
this Purchase Warrant on the books of the Company and shall execute and deliver a new Purchase Warrant or Purchase Warrants of
like tenor to the appropriate assignee(s) expressly evidencing the right to purchase the aggregate number of shares of Common Stock
and Warrants purchasable hereunder or such portion of such number as shall be contemplated by any such assignment.

 

3.2         Restrictions
Imposed by the Securities Act. The securities evidenced by this Purchase Warrant shall not be transferred unless and until:
(i) the Company has received the opinion of counsel for the Holder that the securities may be transferred pursuant to an exemption
from registration under the Securities Act and applicable state securities laws, the availability of which is established to the
reasonable satisfaction of the Company (the Company hereby agreeing that the opinion of Mintz, Levin, Cohn, Ferris, Glovsky and
Popeo, P.C. shall be deemed satisfactory evidence of the availability of an exemption), or (ii) a registration statement or a post-effective
amendment to the Registration Statement relating to the offer and sale of such securities has been filed by the Company and declared
effective by the U.S. Securities and Exchange Commission (the “Commission”) and compliance with applicable
state securities law has been established.

 

4.            Registration
Rights.

 

4.1          Demand
Registration.

 

4.1.1       Grant
of Right. The Company, upon written demand (a “Demand Notice”) of the Holder(s) of at least 51% of the Purchase
Warrants (“Majority Holders”), agrees to register, on one occasion, all or any portion of the shares of Common
Stock, Warrants underlying the Purchase Warrants and shares of Common Stock underlying the Warrants (collectively, the “Registrable
Securities”). On such occasion, the Company will file a registration statement with the Commission covering the Registrable
Securities within sixty (60) days after receipt of a Demand Notice and use its reasonable best efforts to have the registration
statement declared effective promptly thereafter, subject to compliance with review by the Commission; provided, however,
that the Company shall not be required to comply with a Demand Notice if the Company has filed a registration statement with respect
to which the Holder is entitled to piggyback registration rights pursuant to Section 4.2 hereof and either: (i) the Holder has
elected to participate in the offering covered by such registration statement or (ii) if such registration statement relates to
an underwritten primary offering of securities of the Company, until the offering covered by such registration statement has been
withdrawn or until thirty (30) days after such offering is consummated. The demand for registration may be made at any time during
a period of four (4) years beginning on the Commencement Date. The Company covenants and agrees to give written notice of its receipt
of any Demand Notice by any Holder(s) to all other registered Holders of the Purchase Warrants and/or the Registrable Securities
within ten (10) days after the date of the receipt of any such Demand Notice.

 

    	 	3	 

     

    

 

4.1.2       Terms.
The Company shall bear all fees and expenses attendant to the registration of the Registrable Securities pursuant to Section 4.1.1,
but the Holders shall pay any and all underwriting commissions and the expenses of any legal counsel selected by the Holders to
represent them in connection with the sale of the Registrable Securities. The Company agrees to use its reasonable best efforts
to cause the filing required herein to become effective promptly and to qualify or register the Registrable Securities in such
states as are reasonably requested by the Holder(s); provided, however, that in no event shall the Company
be required to register the Registrable Securities in a state in which such registration would cause: (i) the Company to be obligated
to register or license to do business in such state or submit to general service of process in such State, or (ii) the principal
shareholders of the Company to be obligated to escrow their shares of capital stock of the Company. The Company shall cause any
registration statement filed pursuant to the demand right granted under Section 4.1.1 to remain effective for a period of at least
twelve (12) consecutive months after the date that the Holders of the Registrable Securities covered by such registration statement
are first given the opportunity to sell all of such securities. The Holders shall only use the prospectuses provided by the Company
to sell the shares covered by such registration statement, and will immediately cease to use any prospectus furnished by the Company
if the Company advises the Holder that such prospectus may no longer be used due to a material misstatement or omission. Notwithstanding
the provisions of this Section 4.1.2, the Holder shall be entitled to a demand registration under this Section 4.1.2 on only one
(1) occasion and such demand registration right shall terminate on the fifth anniversary of the effectiveness of the registration
statement in accordance with FINRA Rule 5110(f)(2)(G)(iv).

 

4.2          “Piggy-Back”
Registration.

 

4.2.1       Grant
of Right. In addition to the demand right of registration described in Section 4.1 hereof, the Holder shall have the right,
for a period of no more than seven (7) years from the date of effectiveness of the registration statement in accordance with FINRA
Rule 5110(f)(2)(G)(v), to include the Registrable Securities as part of any other registration of securities filed by the Company
(other than in connection with a transaction contemplated by Rule 145(a) promulgated under the Securities Act or pursuant to Form
S-8 or any equivalent form); provided, however, that if, solely in connection with any primary underwritten
public offering for the account of the Company, the managing underwriter(s) thereof shall, in its reasonable discretion, impose
a limitation on the number of shares of common stock which may be included in the Registration Statement because, in such underwriter(s)’
judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, then the Company shall
be obligated to include in such Registration Statement only such limited portion of the Registrable Securities with respect to
which the Holder requested inclusion hereunder as the underwriter shall reasonably permit. Any exclusion of Registrable Securities
shall be made pro rata among the Holders seeking to include Registrable Securities in proportion to the number of Registrable Securities
sought to be included by such Holders; provided, however, that the Company shall not exclude any Registrable
Securities unless the Company has first excluded all outstanding securities, the holders of which are not entitled to inclusion
of such securities in such Registration Statement or are not entitled to pro rata inclusion with the Registrable Securities.

 

4.2.2       Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities pursuant to Section
4.2.1 hereof, but the Holders shall pay any and all underwriting commissions and the expenses of any legal counsel selected by
the Holders to represent them in connection with the sale of the Registrable Securities. In the event of such a proposed registration,
the Company shall furnish the then Holders of outstanding Registrable Securities with not less than thirty (30) days written notice
prior to the proposed date of filing of such registration statement. Such notice to the Holders shall continue to be given for
each registration statement filed by the Company until such time as all of the Registrable Securities have been sold by the Holder.
The holders of the Registrable Securities shall exercise the “piggy-back” rights provided for herein by giving written
notice within ten (10) days of the receipt of the Company’s notice of its intention to file a registration statement. Except
as otherwise provided in this Purchase Warrant, there shall be no limit on the number of times the Holder may request registration
under this Section 4.2.2; provided, however, that such registration rights shall terminate on the sixth
anniversary of the Commencement Date.

 

4.3          General
Terms.

 

4.3.1       Indemnification.
The Company shall indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any registration statement hereunder
and each person, if any, who controls such Holders within the meaning of Section 15 of the Securities Act or Section 20 (a) of
the Securities Exchange Act of 1934, as amended (“Exchange Act”), against all loss, claim, damage, expense or
liability (including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or
defending against any claim whatsoever) to which any of them may become subject under the Securities Act, the Exchange Act or otherwise,
arising from such registration statement but only to the same extent and with the same effect as the provisions pursuant to which
the Company has agreed to indemnify the Underwriters contained in Section 5.1 of the Underwriting Agreement. The Holder(s) of the
Registrable Securities to be sold pursuant to such registration statement, and their successors and assigns, shall severally, and
not jointly, indemnify the Company, against all loss, claim, damage, expense or liability (including all reasonable attorneys’
fees and other expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which they
may become subject under the Securities Act, the Exchange Act or otherwise, arising from information furnished by or on behalf
of such Holders, or their successors or assigns, in writing, for specific inclusion in such registration statement to the same
extent and with the same effect as the provisions contained in Section 5.2 of the Underwriting Agreement pursuant to which the
Underwriters have agreed to indemnify the Company.

 

    	 	4	 

     

    

 

4.3.2       Exercise of Purchase Warrants. Nothing contained in this Purchase Warrant shall be construed as requiring the Holder(s)
to exercise their Purchase Warrants prior to or after the initial filing of any registration statement or the effectiveness thereof.

 

4.3.3      Documents
Delivered to Holders. The Company shall furnish to each Holder participating in any of the foregoing offerings and to each
underwriter of any such offering, if any, a signed counterpart, addressed to such Holder or underwriter, of: (i) an opinion of
counsel to the Company, dated the effective date of such registration statement (and, if such registration statement includes an
underwritten public offering, an opinion dated the date of the closing under any underwriting agreement related thereto), and (ii)
a “cold comfort” letter dated the effective date of such registration statement (and, if such registration includes
an underwritten public offering, a letter dated the date of the closing under the underwriting agreement) signed by the independent
registered public accounting firm which has issued a report on the Company’s financial statements included in such registration
statement, in each case covering substantially the same matters with respect to such registration statement (and the prospectus
included therein) and, in the case of such accountants’ letter, with respect to events subsequent to the date of such financial
statements, as are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to underwriters
in underwritten public offerings of securities. The Company shall also deliver promptly to each Holder participating in the offering
requesting the correspondence and memoranda described below and to the managing underwriter, if any, copies of all correspondence
between the Commission and the Company, its counsel or auditors and all memoranda relating to discussions with the Commission or
its staff with respect to the registration statement and permit each Holder and underwriter to do such investigation, upon reasonable
advance notice, with respect to information contained in or omitted from the registration statement as it deems reasonably necessary
to comply with applicable securities laws or rules of FINRA. Such investigation shall include access to books, records and properties
and opportunities to discuss the business of the Company with its officers and independent auditors, all to such reasonable extent
and at such reasonable times as any such Holder shall reasonably request.

 

4.3.4       Underwriting
Agreement. The Company shall enter into an underwriting agreement with the managing underwriter(s), if any, selected by any
Holders whose Registrable Securities are being registered pursuant to this Section 4, which managing underwriter shall be reasonably
satisfactory to the Company. Such agreement shall be reasonably satisfactory in form and substance to the Company, each Holder
and such managing underwriters, and shall contain such representations, warranties and covenants by the Company and such other
terms as are customarily contained in agreements of that type used by the managing underwriter. The Holders shall be parties to
any underwriting agreement relating to an underwritten sale of their Registrable Securities and may, at their option, require
that any or all the representations, warranties and covenants of the Company to or for the benefit of such underwriters shall
also be made to and for the benefit of such Holders. Such Holders shall not be required to make any representations or warranties
to or agreements with the Company or the underwriters except as they may relate to such Holders, their securities and their intended
methods of distribution.

 

4.3.5      
Documents to be Delivered by Holder(s). Each of the Holder(s) participating in any of the foregoing offerings shall furnish
to the Company a completed and executed questionnaire provided by the Company requesting information customarily sought of selling
security holders.

 

4.3.6      
Damages. Should the registration statement or the effectiveness thereof required by Sections 4.1 and 4.2 hereof be delayed
by the Company or the Company otherwise fails to comply with such provisions, the Holder(s) shall, in addition to any other legal
or other relief available to the Holder(s), be entitled to obtain specific performance or other equitable (including injunctive)
relief against the threatened breach of such provisions or the continuation of any such breach, without the necessity of proving
actual damages and without the necessity of posting bond or other security.

 

    	 	5	 

     

    

 

5.            New
Purchase Warrants to be Issued.

 

5.1          Partial
Exercise or Transfer. Subject to the restrictions in Section 3 hereof, this Purchase Warrant may be exercised or assigned in
whole or in part. In the event of the exercise or assignment hereof in part only, upon surrender of this Purchase Warrant for cancellation,
together with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price and/or transfer tax
if exercised pursuant to Section 2.1 hereto, the Company shall cause to be delivered to the Holder without charge a new Purchase
Warrant of like tenor to this Purchase Warrant in the name of the Holder evidencing the right of the Holder to purchase the number
of Units (or underlying shares of Common Stock and Warrants) purchasable hereunder as to which this Purchase Warrant has not been
exercised or assigned.

 

5.2         Lost
Certificate. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this
Purchase Warrant and of reasonably satisfactory indemnification or the posting of a bond, the Company shall execute and deliver
a new Purchase Warrant of like tenor and date. Any such new Purchase Warrant executed and delivered as a result of such loss, theft,
mutilation or destruction shall constitute a substitute contractual obligation on the part of the Company.

 

6.            Adjustments.

 

6.1          Adjustments
to Exercise Price and Number of Securities. The Exercise Price and the number of shares of Common Stock, Warrants underlying
the Purchase Warrants and shares of Common Stock underlying the Warrants, shall be subject to adjustment from time to time as hereinafter
set forth:

 

6.1.1       Share
Dividends; Split Ups. If, after the date hereof, and subject to the provisions of Section 6.3 below, the number of outstanding
shares of Common Stock is increased by a stock dividend payable in shares of Common Stock or by a split up of shares of Common
Stock or other similar event, then, on the effective day thereof, the number of shares of Common Stock, Warrants underlying the
Purchase Warrants and shares of Common Stock underlying the Warrants, purchasable hereunder shall be increased in proportion to
such increase in outstanding shares, and the Exercise Price shall be proportionately decreased.

 

6.1.2       Aggregation
of Shares. If, after the date hereof, and subject to the provisions of Section 6.3 below, the number of outstanding shares
of Common Stock is decreased by a consolidation, combination or reclassification of shares of Common Stock or other similar event,
then, on the effective date thereof, the number of shares of Common Stock, Warrants underlying the Purchase Warrants and shares
of Common Stock underlying the Warrants, purchasable hereunder shall be decreased in proportion to such decrease in outstanding
shares of Common Stock, and the Exercise Price shall be proportionately increased.

 

6.1.3       Replacement
of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common
Stock other than a change covered by Section 6.1.1 or 6.1.2 hereof or that solely affects the par value of such shares of Common
Stock, or in the case of any share reconstruction or amalgamation or consolidation of the Company with or into another corporation
(other than a consolidation or share reconstruction or amalgamation in which the Company is the continuing corporation and that
does not result in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale
or conveyance to another corporation or entity of the property of the Company as an entirety or substantially as an entirety in
connection with which the Company is dissolved, the Holder of this Purchase Warrant shall have the right thereafter (until the
expiration of the right of exercise of this Purchase Warrant) to receive upon the exercise hereof, for the same aggregate Exercise
Price payable hereunder immediately prior to such event, the kind and amount of shares of stock or other securities or property
(including cash) receivable upon such reclassification, reorganization, share reconstruction or amalgamation, or consolidation,
or upon a dissolution following any such sale or transfer, by a Holder of the number of shares of Common Stock of the Company
obtainable upon exercise of this Purchase Warrant and the underlying Warrants immediately prior to such event; and if any reclassification
also results in a change in shares of Common Stock covered by Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant
to Sections 6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall similarly apply to successive reclassifications,
reorganizations, share reconstructions or amalgamations, or consolidations, sales or other transfers.

 

    	 	6	 

     

    

 

6.1.4      Changes
in Form of Purchase Warrant. This form of Purchase Warrant need not be changed because of any change pursuant to this Section
6.1, and Purchase Warrants issued after such change may state the same Exercise Price and the same number of Units (and underlying
shares of Common Stock and Warrants) as are stated in the Purchase Warrants initially issued pursuant to the Underwriting Agreement.
The acceptance by any Holder of the issuance of new Purchase Warrants reflecting a required or permissive change shall not be
deemed to waive any rights to an adjustment occurring after the Commencement Date or the computation thereof.

 

6.2         Substitute
Purchase Warrant. In case of any consolidation of the Company with, or share reconstruction or amalgamation of the Company
with or into, another corporation (other than a consolidation or share reconstruction or amalgamation which does not result in
any reclassification or change of the outstanding shares of Common Stock), the corporation formed by such consolidation or share
reconstruction or amalgamation shall execute and deliver to the Holder a supplemental Purchase Warrant providing that the holder
of each Purchase Warrant then outstanding or to be outstanding shall have the right thereafter (until the stated expiration of
such Purchase Warrant) to receive, upon exercise of such Purchase Warrant, the kind and amount of shares of stock and other securities
and property receivable upon such consolidation or share reconstruction or amalgamation, by a holder of the number of shares of
Common Stock of the Company for which such Purchase Warrant might have been exercised immediately prior to such consolidation,
share reconstruction or amalgamation, sale or transfer. Such supplemental Purchase Warrant shall provide for adjustments which
shall be identical to the adjustments provided for in this Section 6. The above provision of this Section shall similarly apply
to successive consolidations or share reconstructions or amalgamations.

 

6.3        Elimination
of Fractional Interests. The Company shall not be required to issue certificates representing fractions of a share of Common
Stock or a Warrant upon the exercise of the Purchase Warrant, nor shall it be required to issue scrip or pay cash in lieu of any
fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction
up or down, as the case may be, to the nearest whole number of shares of Common Stock or other securities, properties or rights.

 

7.           
Reservation and Listing. The Company shall at all times reserve and keep available out of its authorized Common Stock, solely
for the purpose of issuance upon exercise of the Purchase Warrants and the shares of Common Stock, Warrants underlying the Purchase
Warrants and shares of Common Stock underlying the Warrants issuable hereunder, such number of shares of Common Stock or other
securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise
of the Purchase Warrants and payment of the Exercise Price therefor, in accordance with the terms hereby, all securities issuable
upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any
shareholder. The Company further covenants and agrees that upon exercise of the Warrants underlying the Purchase Warrants and payment
of the respective Warrant exercise price therefor, all Common Stock and other securities issuable upon such exercise shall be duly
and validly issued, fully paid and non-assessable and not subject to preemptive rights of any stockholder. As long as the Purchase
Warrants shall be outstanding, the Company shall use its commercially reasonable efforts to cause all the shares of Common Stock
and Warrants underlying the Purchase Warrants issuable hereunder and shares of Common Stock underlying the Warrants issuable upon
exercise of the Warrants to be listed (subject to official notice of issuance) on all securities exchanges (or, if applicable on
the OTC Bulletin Board or OTC Markets Group, Inc. or any successor trading market) on which the Common Stock issued to the public
in connection with the Offering may then be listed and/or quoted.

 

8.            Certain
Notice Requirements.

 

8.1          Holder’s
Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent or to
receive notice as a shareholder for the election of directors or any other matter, or as having any rights whatsoever as a shareholder
of the Company. If, however, at any time prior to the expiration of the Purchase Warrants and their exercise, any of the events
described in Section 8.2 shall occur, then, in one or more of said events, the Company shall give written notice of such event
at least fifteen days prior to the date fixed as a record date or the date of closing the transfer books for the determination
of the shareholders entitled to such dividend, distribution, conversion or exchange of securities or subscription rights, or entitled
to vote on such proposed dissolution, liquidation, winding up or sale. Such notice shall specify such record date or the date of
the closing of the transfer books, as the case may be. Notwithstanding the foregoing, the Company shall deliver to each Holder

 WHEREAS, Parent, Medina

conditions set forth in, the Merger Agreement (the “Merger”). 
 WHEREAS, the approval of the Merger and the adoption of

to the consummation of the Merger. 
 WHEREAS, as a condition to the willingness of Parent to enter into the Merger Agreement and as an
inducement and in consideration therefor, the Stockholders have agreed to enter into this Agreement. 

 NOW, THEREFORE, in consideration of the foregoing, the mutual covenants and agreements set forth
herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, intending to be legally bound, the parties hereto agree as follows: 

ARTICLE I 
 VOTING; GRANT
AND APPOINTMENT OF PROXY 
 1.1 Voting. From and after the date hereof until the earlier of (x) the consummation of
the Merger and (y) the termination of the Merger Agreement pursuant to and in compliance with the terms thereof (such earlier date, the “Expiration Date”), each Stockholder irrevocably and unconditionally hereby agrees that at
any meeting (whether annual or special and each adjourned or postponed meeting) of the stockholders of the Company, however called, or in connection with any written consent of the stockholders of the Company, each Stockholder (in such capacity and
not in any other capacity) will (i) appear at such meeting or otherwise cause all of the Securities owned by such Stockholder (whether beneficially or of record) to be counted as present thereat for purposes of calculating a quorum and
(ii) vote or cause to be voted (including by proxy or written consent, if applicable) all of the Securities owned by such Stockholder (whether beneficially or of record): 

(a) with respect to each meeting at which a vote of the Stockholders on the Merger is requested (a “Merger
Proposal”), in favor of such Merger Proposal (and, in the event that such Merger Proposal is presented as more than one proposal, in favor of each proposal that is part of such Merger Proposal), and in favor of any other matter presented or
proposed as to approval of the Merger or any part or aspect thereof or any other transactions or matters contemplated by the Merger Agreement; 

(b) against any Competing Proposal, without regard to the terms of such Competing Proposal, or any other transaction, proposal,
agreement or action made in opposition to adoption of the Merger Agreement or in competition or inconsistent with the Merger and the other transactions or matters contemplated by the Merger Agreement; 

(c) against any other action, agreement or transaction, that is intended, that would or would be reasonably expected, or the
effect of which would or would be reasonably expected, to impede, interfere with, delay, postpone, discourage or adversely affect the Merger or any of the other transactions contemplated by the Merger Agreement or the performance by such Stockholder
of its obligations under this Agreement, including: (i) any extraordinary corporate transaction, such as a merger, consolidation or other business combination involving the Company or any of its Subsidiaries; (ii) a sale, lease or transfer
of a material amount of assets of the Company or any of its Subsidiaries (other than the Merger) or a reorganization, recapitalization or liquidation of the Company or any of its Subsidiaries; (iii) an election of new members to the Company
Board; (iv) any material change in the present capitalization or dividend or distribution policy of the Company or any amendment or other change to the Organizational Documents of the Company or its Subsidiaries, except if previously approved
in writing by Parent or as otherwise expressly provided in the Merger Agreement; or (v) any other material change in the Company’s organizational structure or business, except if previously approved in writing by Parent or as otherwise
expressly provided in the Merger Agreement; 

  
 2 

 (d) against any action, proposal, transaction or agreement that would or would
reasonably be expected to result in a breach in any respect of any covenant, representation or warranty or any other obligation or agreement of the Company contained in the Merger Agreement, or of any Stockholder contained in this Agreement; and

 (e) in favor of any other matter necessary or desirable to the consummation of the transactions contemplated by the Merger
Agreement, including the Merger (clauses (a) through (e) of this Section 1.1, the “Required Votes”). 

1.2 Grant of Irrevocable Proxy; Appointment of Proxy. 

(a) From and after the date hereof until the Expiration Date, each Stockholder hereby irrevocably and unconditionally grants
to, and appoints, Parent and any designee of Parent (determined in Parent’s sole discretion) as such Stockholder’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of such Stockholder, to
vote or cause to be voted (including by proxy or written consent, if applicable) its Securities in accordance with the Required Votes. 

(b) Except for the irrevocable proxies previously granted under the Existing Voting Agreement, each Stockholder hereby
represents that any proxies heretofore given in respect of the Securities, if any, are revocable, and hereby revokes such proxies. The irrevocable proxies granted under the Existing Voting Agreement are hereby waived as and to the extent set forth
in Section 1.3. 
 (c) Each Stockholder hereby affirms that the irrevocable proxy set forth in this
Section 1.2 is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Stockholder under this Agreement. Each Stockholder hereby further
affirms that the irrevocable proxy set forth in this Section 1.2 is coupled with an interest and, except upon the occurrence of the Expiration Date, is intended to be irrevocable. Each Stockholder agrees, until the Expiration Date, to
vote its Securities in accordance with Section 1.1(a) through Section 1.1(e) above as instructed by Parent in writing. The parties agree that the foregoing is a voting agreement. 

1.3 Waiver of the Existing Voting Agreement. Pursuant to Section 6.8 of the Existing Voting Agreement, Holdco hereby waives
the provisions of the Existing Voting Agreement to the extent necessary to allow each of Graham, Bahr and WHR to enter into and comply with all of its obligations under this Agreement, including providing the Required Vote under
Section 1.1 and granting the proxies under Section 1.2; provided, however, that such waiver shall be effective only until the date that such Stockholders have no further obligations under this Agreement. For the
avoidance of doubt, except to the extent expressly set forth in the immediately preceding sentence, all of the rights of Holdco, and all of the obligations of Graham, Bahr and WHR, under the Existing Voting Agreement and all provisions of the
Existing Voting Agreement shall remain unmodified and in full force and effect, and nothing herein shall amend, modify or otherwise affect the Existing Voting Agreement or the rights or obligations thereunder of the parties thereto. For the further
avoidance of doubt, the Stockholders agree and 

  
 3 

 
acknowledge that the transfer restrictions set forth in Section 3.1 of the Existing Voting Agreement shall not prohibit, prevent, impede or delay the conversion of any Securities subject to
the Existing Voting Agreement into shares of Parent Common Stock in accordance with Article III of the Merger Agreement. 
 1.4
Restrictions on Transfers. 
 (a) Except as set forth in Section 1.4(b), each Stockholder hereby agrees that, from
the date hereof until the Expiration Date, it shall not, directly or indirectly, except in connection with the consummation of the Merger and as expressly provided for in the Merger Agreement, (i) sell, transfer, assign, tender in any tender or
exchange offer, pledge, encumber, hypothecate or similarly dispose of (by merger, by testamentary disposition, by operation of law or otherwise), either voluntarily or involuntarily, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, assignment, pledge, Encumbrance, hypothecation or other disposition of (by merger, by testamentary disposition, by operation of Law or otherwise), any Securities, (ii) deposit any Securities
into a voting trust or enter into a voting agreement or arrangement or grant any proxy, consent or power of attorney with respect thereto other than, and that is inconsistent with, this Agreement, or (iii) agree (regardless of whether in
writing) to take any of the actions referred to in the foregoing clause (i) or (ii). 
 (b) Notwithstanding the
provisions of Section 1.4(a) above, after the Company Stockholder Approval has been obtained in accordance with the Merger Agreement, (x) Holdco may distribute in accordance with its Organizational Documents any or all of its
Securities to Natural Gas Partners VIII, L.P. (“NGP VIII”), Natural Gas Partners IX, L.P. (“NGP IX”) and NGP IX Offshore Holdings, L.P. (“NGP IX Offshore” and, together with NGP VIII and NGP IX, the
“NGP Funds”) and the holders of Incentive Units (as such term is defined in Amended and Restated Limited Liability Company Agreement of Holdco dated June 4, 2014) of Holdco and (y) the NGP Funds may distribute in
accordance with their respective Organizational Documents any or all such Securities to their respective limited partners and, as applicable, to G.F.W. Energy VIII, L.P. (as general partner of NGP VIII, “GFW VIII”)) or G.F.W. Energy
IX, L.P. (as general partner of NGP IX, “GFW IX”). Upon such distribution, this Agreement shall no longer apply to any Securities distributed pursuant to this Section 1.4(b) to any Person other than Graham, Bahr, WHR and
any Person that received such distribution in its capacity as a general partner of one of the NGP Funds. Notwithstanding the foregoing, as a condition to receiving any distribution of Securities pursuant to this Section 1.4(b), each of
GFW VIII and GFW IX shall execute a joinder, in form and substance acceptable to Parent in its reasonable judgment, pursuant to which each such Person shall become a “Stockholder” for purposes of this Agreement as if an original signatory
hereto.

providing for a Competing Proposal or (e) resolve, agree or publicly propose to, or permit the Company or any of its Subsidiaries or any of its or their Representatives to agree or publicly propose to take any of the actions referred to in this

2.2 Notification. Each Stockholder shall, and shall cause its Affiliates and use reasonable best efforts to cause its
Representatives to, immediately cease, and cause to be terminated, any solicitation, encouragement, discussion or negotiation with any Person conducted heretofore with respect to a Competing Proposal or any indication of interest that would or would
reasonably be expected to lead to a Competing Proposal. From and after the date hereof until the Expiration Date, each Stockholder shall advise Parent as promptly as practicable (and in no event later than 48 hours) of the receipt by such

with respect to material oral communications, a written summary of such correspondence or communications, between: (x) on the one hand, the Company, such Stockholder or any of their Representatives or Affiliates; and (y) on the other hand,
the Person that made or submitted such Competing Proposal or any Representative of such Person. Each Stockholder agrees that neither it nor any of its Affiliates has entered into or shall enter into any agreement with any Person that prohibits the
Company or such Stockholder from either providing any information to Parent in accordance with this Section 2.2 or otherwise complying with any of its obligations pursuant to this Section 2.2. 

2.3 Exception. Notwithstanding anything in this Agreement to the contrary, each Stockholder, directly or indirectly through one

case subject to the restrictions and limitations set forth in Section 6.3 of the Merger Agreement. 

  
 5 

 2.4 Capacity. Each Stockholder is signing this Agreement solely in its capacity as
a Company stockholder, and nothing contained herein shall in any way limit or affect any actions taken by any Representative of such Stockholder in his or her capacity as a director, officer or employee of the Company, and no action taken in any
such capacity as a director, officer or employee shall be deemed to constitute a breach of this Agreement. 
 ARTICLE III 

REPRESENTATIONS, WARRANTIES AND COVENANTS 

OF THE STOCKHOLDERS

except for filings with the SEC by such Stockholder; (e) such Stockholder owns, beneficially and of record, or controls the Securities set forth opposite such Stockholder’s name on Exhibit A attached hereto; and (f) such

Parent Common Stock or such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Parent Common Stock or such other securities, in cash or otherwise. In
furtherance of the foregoing, Parent and any duly appointed transfer agent for the registration or transfer of the Restricted Parent Securities described herein are hereby authorized to decline to make any transfer of Restricted Parent Securities if
such transfer would constitute a violation or breach of this Section 3.2. 
 3.3 Standstill. No Stockholder shall,
during the period commencing on the Closing Date and continuing for 12 months after the Closing Date (such period, the “Standstill Period”), unless such action shall have been specifically invited in writing by the Parent Board (it
being understood that execution of this Agreement by Parent does not constitute such an invitation), and each Stockholder will direct its Representatives not to, directly or indirectly:

 (iii) any recapitalization, restructuring, liquidation, dissolution or other

 (f) advise, assist, or
knowingly encourage, or direct any Person to advise, assist or knowingly encourage any other persons with respect to any of the conduct prohibited by this Section 3.3. 

Notwithstanding the preceding provisions of this Section 3.3, a Stockholder and its Representatives may request any amendment,
waiver or consent described in clause (e) from, Parent’s Chief Executive Officer or Parent’s entire Board of Directors (or any committee thereof), as long as all such request is kept strictly confidential by such Stockholder
and its Representatives and would not reasonably be expected to require public disclosure by any party pursuant to any applicable laws or stock exchange regulations. 

3.4 Certain Other Agreements. Each Stockholder hereby: 

(a) irrevocably waives, and agrees not to exercise, any rights of appraisal or rights of dissent from the Merger that such
Stockholder may have with respect to the Securities; 
 (b) agrees to promptly notify Parent and the Company of the number of
any new Securities acquired by such Stockholder after the date hereof and prior to the Expiration Date, it being understood, for the avoidance of doubt, that any such Securities shall be subject to the terms of this Agreement as though owned by such

Proxy Statement such Stockholder’s identity and ownership of the Securities and the nature of such Stockholder’s commitments, arrangements and understandings under this Agreement; and 

(d) shall, and hereby does, authorize the Company or its counsel to notify the Company’s transfer agent that there is a
stop transfer order with respect to all of the Securities (and that this Agreement places limits on the voting and transfer of such Securities); provided, however, that Company or its counsel may further notify the
Company’s transfer agent to lift and vacate the stop transfer order (i) with respect to the Securities following the Expiration Date solely to the extent to effect the consummation of the Merger in accordance with the Merger Agreement and
(ii) to permit the transfers contemplated by Section 1.4(b).

5.3 Amendments; Extension; Waivers. Any provision of this Agreement may be amended or waived if, and only if, such amendment or
waiver is in writing and signed (i) in the case of an amendment, by the Company and by Parent, on the one hand, and each Stockholder, on the other hand and (ii) in the case of a waiver, by the Company and the party (or parties) against
whom the waiver is to be effective. Subject to the prior written approval of the Company, Parent may, to the extent legally allowed: (a) extend the time for the performance of any of the obligations or acts of the other parties hereunder,
(b) waive any inaccuracies in the representations and warranties of the other parties contained herein or in any document delivered pursuant hereto, or (c) waive compliance with any of the agreements or conditions of the other parties
contained herein. Notwithstanding the foregoing, no failure or delay by a party in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other
right hereunder. No agreement on the part of a party to any such extension or waiver shall be valid unless set forth in an instrument in writing signed on behalf of such party. 

5.4 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the
parties (whether by operation of law or otherwise) without the prior written consent of the other party and the Company. Subject to the preceding sentence and except as set forth to the contrary in Section 1.4(b), this Agreement will be
binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and permitted assigns. Any purported assignment in violation of this Section 5.4 shall be void. 

5.5 No Partnership, Agency, or Joint Venture. This Agreement is intended to create, and creates, a contractual relationship and
is not intended to create, and does not create, any agency, partnership, joint venture or any like relationship between the parties. 

5.6 Entire Agreement. This Agreement, together with the Merger Agreement and the Confidentiality Agreement, constitute the
entire agreement, and supersede all prior agreements and understandings, both written and oral, among the parties, with respect to the subject matter hereof. 

  
 11 

 5.7 Third-Party Beneficiaries. Nothing in this Agreement, express or implied, is
intended to or shall confer upon any Person other than the parties any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement; provided, however, that the Company is an intended third party beneficiary
of the provisions of Section 3.4 and Articles IV and V. 
 5.8 Jurisdiction; Specific Performance;
Waiver of Jury Trial. 
 (a) THE PARTIES IRREVOCABLY SUBMIT TO THE JURISDICTION OF THE COURT OF CHANCERY OF THE STATE
OF DELAWARE OR, IF THE COURT OF CHANCERY OF THE STATE OF DELAWARE OR THE DELAWARE SUPREME COURT DETERMINES THAT, NOTWITHSTANDING SECTION 111 OF THE DGCL, THE COURT OF CHANCERY DOES NOT HAVE OR SHOULD NOT EXERCISE SUBJECT MATTER JURISDICTION OVER
SUCH MATTER, THE SUPERIOR COURT OF THE STATE OF DELAWARE AND THE FEDERAL COURTS OF THE UNITED STATES OF AMERICA LOCATED IN THE STATE OF DELAWARE SOLELY IN CONNECTION WITH ANY DISPUTE THAT ARISES IN RESPECT OF THE INTERPRETATION AND ENFORCEMENT OF
THE PROVISIONS OF THIS AGREEMENT AND THE DOCUMENTS REFERRED TO IN THIS AGREEMENT OR IN RESPECT OF THE TRANSACTIONS CONTEMPLATED HEREBY, AND HEREBY WAIVE, AND AGREE NOT TO ASSERT, AS A DEFENSE IN ANY ACTION, SUIT OR PROCEEDING FOR INTERPRETATION OR
ENFORCEMENT HEREOF OR ANY SUCH DOCUMENT THAT IT IS NOT SUBJECT THERETO OR THAT SUCH ACTION, SUIT OR PROCEEDING MAY NOT BE BROUGHT OR IS NOT MAINTAINABLE IN SAID COURTS OR THAT VENUE THEREOF MAY NOT BE APPROPRIATE OR THAT THIS AGREEMENT OR ANY SUCH
DOCUMENT MAY NOT BE ENFORCED IN OR BY SUCH COURTS, AND THE PARTIES IRREVOCABLY AGREE THAT ALL CLAIMS WITH RESPECT TO SUCH ACTION, SUIT OR PROCEEDING SHALL BE HEARD AND DETERMINED EXCLUSIVELY BY SUCH A DELAWARE STATE OR FEDERAL COURT. THE PARTIES
HEREBY CONSENT TO AND GRANT ANY SUCH COURT JURISDICTION OVER THE PERSON OF SUCH PARTIES AND OVER THE SUBJECT MATTER OF SUCH DISPUTE AND AGREE THAT MAILING OF PROCESS OR OTHER PAPERS IN CONNECTION WITH SUCH ACTION, SUIT OR PROCEEDING IN THE MANNER
PROVIDED IN SECTION 5.2 OR IN SUCH OTHER MANNER AS MAY BE PERMITTED BY LAW SHALL BE VALID AND SUFFICIENT SERVICE THEREOF. 

(b) The parties agree that irreparable damage, for which monetary damages would not be an adequate remedy, would occur in the
event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached by the parties. Prior to the termination of this Agreement pursuant to Article IV, it is accordingly
agreed that the parties and the Company shall be entitled to an injunction or injunctions, or any other appropriate form of specific performance or equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and
provisions hereof in any court of competent jurisdiction, in each case in accordance with this Section 5.8(b), this being in addition to any other remedy to which 

  
 12 

 
they are entitled under the terms of this Agreement at law or in equity. Each party accordingly agrees not to raise any objections to the availability of the equitable remedy of specific
performance to prevent or restrain breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of such party under this Agreement all in accordance with the terms of this Section 5.8(b). Each party
further agrees that no other party or any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 5.8(b), and each
party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument. 

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE
COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN
THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (II) SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THE FOREGOING WAIVER; (III) SUCH PARTY MAKES THE FOREGOING WAIVER VOLUNTARILY AND (IV) SUCH PARTY HAS
BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 5.8(c). 

5.9 Governing Law. THIS AGREEMENT, AND ALL CLAIMS OR CAUSES OF ACTION (WHETHER IN CONTRACT OR TORT) THAT MAY BE BASED UPON,
ARISE OUT OF RELATE TO THIS AGREEMENT, OR THE NEGOTIATION, EXECUTION OR PERFORMANCE OF THIS AGREEMENT, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO THE PRINCIPLES OF CONFLICTS OF
LAW THEREOF.
