Re: Employment Agreement with Dynatronics Corporation

 

Dear Chris,

 

This letter (this “Agreement”)
sets forth the terms of your employment as Chief Executive Officer
of Dynatronics Corporation, a Utah corporation (the
“Company”).
Your employment under this Agreement is conditioned on your
satisfactory completion of certain requirements, as more fully
explained below.

 

Agreement:

 

Subject to the following terms and conditions, it is agreed as
follows:

 

	

Duties

 

	
 

	

In your capacity as Chief Executive Officer,
you will perform duties and responsibilities that are commensurate
with this position as the Company’s principal executive
officer, as well as such other duties as may be assigned to you
from time to time. You will report directly to the Chairman of the
Board of Directors of the Company (the “Board”). You
will also serve as a member of the Board, for no additional
compensation. You will have direct supervisory responsibility for
and receive reports from the heads of the Company’s operating
divisions and executive officers. You agree to devote your full
business time, attention and best efforts to the performance of
your duties and to the furtherance of the Company’s
interests. Notwithstanding the foregoing, nothing in this letter
shall preclude you, from devoting reasonable periods of time to
charitable and community activities, and managing personal
investment assets, provided that none of these activities
interferes with the performance of your duties hereunder or creates
a conflict of interest in the judgment of the Board. The policy of
the Company is that all outside board of director service,
including charitable and community activities, be pre-approved by
the Board. As we have discussed, the Board’s approval of this
Agreement will include its consent for your service on the boards
of directors of the corporations indicated in the attached
Schedule I, “Approved
Directorships”.

 

	

Location

 

	
 

	

The Company’s principal executive offices are currently
located in Cottonwood Heights, Utah and Eagan, Minnesota. Your
duties will require you to be onsite regularly at our principal
offices and divisional facilities a minimum of two weeks each
month, which will require you to travel as needed to properly
fulfill your employment duties and responsibilities. While you may
otherwise work from home so long as the Board determines that this
arrangement continues to meet the needs of the Company, you
understand that your direct reports and any administrative staff
reporting to you will work out of one of our existing locations.
The Company will not provide for an office or administrative staff
except at one of its existing locations.

 

	

Start Date

 

	
 

	

Subject to satisfaction of all of the
conditions described in this Agreement, your employment by the
Company will commence on a mutually acceptable start date to be
determined, but projected to be not later than June 27, 2018
(“Start
Date”).

 

 

 

 

 

 

	

Base Salary

 

	
 

	

In consideration of your services, you will be paid an annual base
salary of $275,000 per year, payable in accordance with the
standard payroll practices of the Company and subject to all
withholdings and deductions as required by law.

 

	

Annual Bonus

 

	
 

	

During your employment, you will be eligible
to receive an annual bonus, payable at such times and in such
amounts, as determined by the Compensation Committee of the Board
(“Compensation
Committee”), with a maximum payout opportunity of 30%
of base salary. Actual payments will be determined based on a
combination of Company results and individual performance against
the applicable quantitative and qualitative performance goals
established by the Compensation Committee. Any annual bonus with
respect to a particular fiscal year will be paid within three (3)
months following the end of the year. You must remain continuously
employed through the bonus payment date to be eligible to receive
an annual bonus payment for a particular fiscal year. Your first
annual bonus will be payable after the completion of the 2019
fiscal year (which ends on June 30th).

 

	

Equity Grants

 

	
 

	

For each full fiscal year of employment, you
will be eligible to receive an annual equity award, which may be in
the form of restricted stock units, stock options or a combination
of such awards of between $150,000 and $200,000, as determined by
the Compensation Committee. At the next regularly scheduled meeting
of the Compensation Committee following your Start Date, the
Company will recommend to the Compensation Committee that it grant
you, the initial such annual equity award in the form of a
restricted stock award of 50,000 shares and a stock option for the
purchase of 50,000 shares of common stock; the estimated aggregate
grant date fair value of this award is approximately $200,000. The
actual number of shares of restricted stock and stock options
included in any future equity awards hereunder will be determined
by the Compensation Committee. The value of restricted stock awards
will be based on the market price of the Company’s common
stock on the date of grant. The value of stock options will be
based on a grant date fair value generally estimated using a
Black-Scholes or similar model. Equity awards will be subject to
the terms and conditions of the Company’s 2015 Equity
Incentive Award Plan or a successor plan adopted by the Company
(“Plan”) and an applicable
award agreement (“Award Agreement”). The
initial equity award above will vest in four equal amounts annually
commencing 25% with the first anniversary of the Start Date and 25%
each year thereafter until fully vested, subject to the conditions
and terms of the Plan and the Award Agreement.

 

	

Benefits and Perquisites

	
 

	

You will be eligible to participate in the
employee benefit plans and programs generally available to the
Company’s senior executives, as outlined in the enclosed
“Dynatronics Benefits Guide 2018” which is attached
as Exhibit A and incorporated herein by reference,
subject to the terms and conditions of such plans and programs. You
will also be entitled to the fringe benefits and perquisites that
may be made available from time to time to other top executives of
the Company at the discretion of the Compensation Committee, in
accordance with and subject to the eligibility and provisions of
such plans and programs. The Company reserves the right to amend,
modify or terminate any of its benefit plans or programs at any
time and for any reason.

 

	

Withholding

	
 

	

All forms of compensation paid to you as an employee of the Company
shall be less all applicable withholdings.

Expenses

	
 

	

You will be entitled to reimbursement for reasonable and necessary
out-of-pocket business and travel expenses (including economy
airfare, and reasonable hotel accommodations while travelling away
from your home) incurred by you in connection with the performance
of your duties in accordance with the Company's expense
reimbursement policies and procedures.

 

	

At-will Employment

	
 

	

Your employment will be for no specific period of time.
Rather, your employment will be
at-will, meaning that you or the Company may terminate the
employment relationship at any time, with or without cause, and
with or without notice and for any reason or no particular
reason. Although your
compensation and benefits may change from time to time, the at-will
nature of your employment may only be changed by an express written
agreement signed by an authorized officer of the
Company.

 

	

Indemnification

	
 

	

You will be covered under the Company’s Directors and
Officers Liability policy. In addition, Utah corporation law and
the Company’s articles of incorporation and bylaws, each as
amended, provide certain indemnification rights and limitation of
liability for officers and directors of the Company performing
their duties in good faith. In addition, the Company has
entered into indemnification agreements with its Board and certain
of its executive officers.

 

	

Securities and Exchange Commission Regulations

	
 

	

As an executive officer of a public company, you will be subject to
rules and regulations of the Securities and Exchange Commission
(“SEC”)
and the Nasdaq Stock Exchange (“NASDAQ”), including
requirements that you report your beneficial ownership of and
trading activity involving the Company’s equity securities
and file reports with the SEC. We will provide training on these
requirements and assist you in complying with all regulations.
These regulations limit when you may trade our securities. In
addition, we are required to include information regarding you and
your education and professional background to the SEC and NASDAQ.
You will be required to comply with these regulations. A copy of
the Company’s Insider Trading Policy is attached hereto
as Exhibit B. This Agreement,
and your employment hereunder, are conditioned, among other things,
upon your representation and warranty that you are not under any
disciplinary bar or restriction from the SEC, NASDAQ or any other
regulatory agency from serving as an executive officer of a public
company.

 

	

Representations; Prior Restrictions and Covenants

	
 

	

Upon execution of this Agreement you represent that you have read
and understood, and that you accept all of the terms of employment
as provided in this Agreement, that you have not relied on any
agreements or representations, express or implied, that are not set
forth expressly in this Agreement, and that this Agreement
supersedes all prior and contemporaneous understandings,
agreements, representations and warranties, both written and oral,
with respect to the subject matter of this Agreement. Furthermore,
by executing this Agreement, you represent that you are able to
accept this position and carry out the work that it would involve
without breaching any legal restrictions on your activities, such
as non-competition, non-solicitation or other work-related
restrictions imposed by a current or former employer. You and the
Company agree that we have no interest in any information you may
have that is deemed proprietary or confidential under any
restrictive covenants with any prior employer or other third party.
You represent that you will inform the Company about any such
restrictions and provide the Company with as much information about
them as possible, including any agreements between you and your
current or former employer describing such restrictions on your
activities. You further confirm that you will not remove or take
any documents or proprietary data or materials of any kind,
electronic or otherwise, with you from your current or former
employer without written authorization from your current or former
employer, nor will you use or disclose to the Company, directly or
indirectly, any such confidential information during the course and
scope of your employment with the Company. If you have any
questions about the ownership of particular documents or other
information, you should discuss such questions with your former
employer before removing or copying the documents or
information.

Employee Non-Solicitation Covenants and Acknowledgment of At-Will
Employment” (“Confidentiality

any reason other than for Cause, 50% of the initial equity grant
made to you will vest immediately upon your termination, subject to

BACKSTOP AND SUBSCRIPTION AGREEMENT

 

This BACKSTOP AND SUBSCRIPTION AGREEMENT
(this “Subscription Agreement”) is entered into this 25th day of June, 2018, by and between Hennessy Capital
Acquisition Corp. III, a Delaware corporation (the “Issuer”), and Nomura Securities International, Inc., a corporation
formed under the laws of the State of New York (“Subscriber”).

 

WHEREAS, the Issuer has entered into that
certain Purchase Agreement, dated as of June 25, 2018 (as may be amended or supplemented from time to time, the “Purchase
Agreement”), by and between the Issuer and JFL-NRC-SES Partners, LLC, a Delaware limited liability company (“NRC
Seller”), pursuant to which NRC will sell to the Issuer, and the Issuer will acquire from NRC Seller, all of the issued
and outstanding membership interests of NRC Group Holdings, LLC, a Delaware limited liability company (“NRC”),
on the terms and subject to the conditions set forth therein (the “Acquisition,” and the consummation of the
Acquisition in accordance with the Purchase Agreement, the “Acquisition Closing”);

 

WHEREAS, in connection with, and subject
to completion of, the closing of the Acquisition, Subscriber desires to subscribe for, and purchase from, the Issuer shares of
the Issuer’s 7.00 % Series A Convertible Cumulative Preferred Stock, par value $0.0001 per share, having terms substantially
consistent with those set forth in the form of certificate of designations attached as Exhibit A hereto (the “Certificate
of Designations” and, such shares, the “Preferred Shares”), for a cash purchase price of $100.00 per
Preferred Share, and the Issuer desires to issue and sell to Subscriber that number of Preferred Shares as set forth in Section
1 hereof in consideration of payment of the cash purchase price therefor by or on behalf of Subscriber to the Issuer on or
prior to the Closing (as defined below); and

 

WHEREAS, in connection with, and subject
to completion of, the Acquisition, Subscriber also desires to acquire, at any one time or from time to time, commencing on the
date hereof and through the Purchase Deadline (as defined below) and the Acquisition Closing (if required pursuant to Section
2(a)(iv) below), shares of the Issuer’s common stock, par value $0.0001 per share (the “Common Shares”),
for aggregate cash consideration of up to $25.0 million (the “Backstop Commitment”), in consideration of the
payment of the cash fees by or on behalf of the Issuer to Subscriber as set forth in Section 2(b) hereof.

 

NOW, THEREFORE, in consideration of the
foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending
to be legally bound hereby, the parties hereto hereby agree as follows:

 

1.       Preferred
Share Subscription.

 

(a)       Subject
to the terms and conditions hereof and the substantially concurrent Acquisition Closing, Subscriber hereby agrees to subscribe
for and purchase, and the Issuer hereby agrees to issue and sell to Subscriber, upon payment of the aggregate cash purchase price
of $75.0 million, 750,000 Preferred Shares (such subscription and issuance, the “Base Subscription”). In addition,
to the extent the Issuer is unable to enter into one or more backstop and/or subscription agreements with other “accredited
investor(s)” (as such term is defined in Rule 501 under the Securities Act of 1933, as amended (the “Securities
Act”)) with respect to the purchase, prior to or concurrent with the Acquisition Closing, of $25.0 million of additional
Preferred Shares and/or $25.0 million of Common Shares in the aggregate, the Issuer may deliver a written notice to Subscriber,
not less than two (2) business days prior to the scheduled Acquisition Closing date, setting forth the number of additional Preferred
Shares (not to exceed 250,000 Preferred Shares in the aggregate) (the “Additional Preferred Shares”) to be issued
and sold by the Issuer to Subscriber for a cash purchase price of $100.00 per Preferred Share, and Subscriber hereby agrees to
so subscribe for and purchase such number of Additional Preferred Shares in such circumstances. The subscription for, and issuance
of, any Additional Preferred Shares pursuant to the immediately preceding sentence (such subscription and issuance (if any), together
with the Base Subscription, the “Preferred Subscription”) shall be consummated concurrently with the Closing
of the Base Subscription. Notwithstanding the foregoing, and for the avoidance of doubt, if the Purchase Agreement is terminated
in accordance with its terms prior to the Acquisition Closing, then Subscriber’s obligations to proceed with the Preferred
Subscription under this Section 1(a) shall immediately terminate and be extinguished.

 

     

     

    

 

(b)       Notwithstanding
anything herein to the contrary, (i) Subscriber shall use its reasonable best efforts to exercise its right to the Preferred Subscription
by having one or more U.S. citizens (within the meaning of the Jones Act (as defined below)) (the “Direct Purchasers”),
prior to the Closing, enter into subscription agreements acceptable to the Issuer (with substantially similar closing conditions
and representations and warranties as those contained in this Subscription Agreement) with the Issuer for the direct purchase from
the Issuer of the Preferred Shares (the “Direct Subscription Agreements”) (such that Subscriber does not take
title to such Preferred Shares) for the Issuer at all times (including from and after the Closing) to the extent necessary to satisfy
the U.S. citizenship requirements set forth in the Jones Act, and otherwise to the extent necessary to comply with the Issuer’s
amended and restated certificate of incorporation (including the Certificate of Designations) and bylaws in effect as of the Acquisition
Closing, and (ii) if prior to the Closing an insufficient amount of Direct Subscription Agreements of the Preferred Subscription
as required by the immediately preceding clause (i) have been executed, then in lieu of purchasing the Preferred Shares pursuant
to the portion of the Preferred Subscription retained by the Subscriber, the Subscriber shall acquire such alternative securities
or other contractual obligations of the Issuer as the Issuer shall structure such that the Issuer at all times (including from
and after the Closing) to the extent required satisfies the U.S. citizenship requirements set forth in the Jones Act, provided
that such alternative securities or other contractual obligations have substantially similar economic terms as the Preferred Shares,
including economic terms based on a theoretical conversion into (or exercise for) Preferred Shares or Common Shares. For the avoidance
of doubt, any subsequent purchaser or transferee who acquires such alternative securities or other contractual obligations of the
Issuer from the Subscriber (as described in clause (ii) of the immediately preceding sentence), including from and after the Closing,
shall be entitled to convert (or exercise for) such alternative securities into Preferred Shares or Common Shares, to the extent
such conversion or exercise will permit the Issuer at all times (including from and after the Closing) to satisfy the U.S. citizenship
requirements set forth in the Jones Act and complies with the Issuer’s amended and restated certificate of incorporation
(including the Certificate of Designations) and bylaws in effect as of the Acquisition Closing. Neither Subscriber’s payment
obligations under this Subscription Agreement nor the aggregate amount of the Preferred Subscription shall at any time be reduced
or otherwise affected as a result of its purchase of any such alternative securities or contractual obligations in lieu of the
Preferred Shares contemplated by the immediately preceding clause (ii), and no Direct Subscription Agreements shall relieve Subscriber
of an obligation to effect such Preferred Subscription pursuant to the terms of this Subscription Agreement in the event any such
Direct Purchaser fails to so subscribe for and purchase Preferred Shares pursuant to the terms of any Direct Subscription Agreement
as contemplated by the immediately preceding clause (i). “Jones Act” means, collectively, the U.S. citizenship
and cabotage laws principally contained in 46 U.S.C. § 50501 and 46 U.S.C. Chapters 121 and 551 and any successor statutes
thereto, together with the rules and regulations promulgated thereunder by the U.S. Coast Guard and the U.S. Maritime Administration
enforcing, administering and interpreting such laws, statutes, rules and regulations, in each case as amended or supplemented from
time to time, relating to the ownership and operation of U.S.-flag vessels in the carriage or transport of merchandise and/or other
materials and/or passengers in the coastwise trade of the United States of America within the meaning of 46 U.S.C. Chapter 551
and any successor statutes thereto, as amended or supplemented from time to time.

 

2.       Common
Share Backstop and Subscription; Commitment Fees.

 

(a)(i)       Subscriber
covenants and agrees that until the earlier of the (A) closing date of the Acquisition or (B) Termination Date (as defined
in the Purchase Agreement), it shall not, and shall ensure that each of its Affiliates does not, Transfer any Common Shares. For
purposes hereof, “Affiliate” shall mean affiliate as such term is defined in Rule 12b-2 of the Securities
Exchange Act of 1934, as amended (the “Exchange Act”), including, without limitation,
any entity for which Subscriber directly or indirectly serves as investment adviser or manager; and “Transfer”
shall mean any direct or indirect transfer, redemption, disposition or monetization in any manner whatsoever, including, without
limitation, through redemption election or any derivative transactions.

 

      (ii)       Subscriber
covenants and agrees that it shall, and shall cause each of its Affiliates to, (A) vote its Common Shares that it owns as
of the record date for the Special Meeting (as defined below) in favor of the Acquisition and the other proposals of the Issuer
set forth in its proxy statement (the “Proxy Statement”) to be filed with the Securities and Exchange Commission
(the “SEC”) in connection with a special meeting of Issuer stockholders (the “Special Meeting”)
to be held to approve, among other things, the Acquisition, and (B) not exercise its redemption rights with respect to any
Common Shares in connection with the Special Meeting.

 

    	 	2	 

     

    

 

(iii)       Commencing
on the date hereof and through the close of business on the third Trading Day (as defined below) prior to the Special Meeting (the
“Purchase Deadline”), Subscriber shall (provided it is lawful to do so and to the extent requested by the Issuer)
use reasonable best efforts to purchase Common Shares, at any one time or from time to time and in such amount or amounts as directed
by the Issuer, for an aggregate purchase price up to (but not exceeding) the Backstop Commitment. All such purchases under this
Section 2(a)(iii) shall be made by Subscriber via one or more open market purchases or in one or more privately negotiated
transactions with one or more third parties, including through forward contracts, provided that: (a) any such privately negotiated
transactions settle no later than, and are conditioned upon, the substantially concurrent Acquisition Closing, and (b) Subscriber
shall not be required to purchase any Common Shares at a price in excess of $10.25 per share. On the date immediately following
the Purchase Deadline, and at such other times as may be requested by the Issuer, Subscriber shall (x) notify the Issuer in
writing of the number of Common Shares so purchased pursuant to this Section 2(a)(iii) (the “Market Shares”)
and the aggregate purchase price paid therefor by Subscriber and (y) in the case of any Market Shares acquired in privately
negotiated transactions with one or more third parties, provide the Issuer with all documentation reasonably requested by the Issuer
and its advisors (including without limitation, its legal counsel) and its transfer agent and proxy solicitor to confirm that:
(A) Subscriber purchased, or has contracted to purchase, such Market Shares, and (B) the seller of such Market Shares
has provided to Subscriber a representation that (I) the seller voted such Market Shares in favor of the Acquisition and the
other proposals of the Issuer set forth in the Proxy Statement and (II) the seller of such Market Shares did not exercise
its redemption rights with respect to such Market Shares in connection with the Special Meeting. Notwithstanding the foregoing,
and for the avoidance of doubt, if the Purchase Agreement is terminated in accordance with its terms prior to the Acquisition Closing,
then Subscriber’s obligations to purchase Common Shares under this Section 2(a)(iii) shall immediately terminate and
be extinguished. For purposes hereof, “Trading Day” shall mean a day during which trading in the Common Shares
generally occurs on the NYSE American or, if the Common Shares are not then listed on the NYSE American, on the principal other
national or regional securities exchange on which the Common Shares are then listed or, if the Common Shares are not listed on
a national or regional securities exchange, on the principal other market on which the Common Shares are then listed or admitted
for trading.

 

(iv)        In
the event Subscriber has not acquired a sufficient number of Market Shares pursuant to Section 2(a)(iii) hereof to satisfy
in full its Backstop Commitment, Subscriber hereby irrevocably subscribes for and agrees, subject to the substantially concurrent
Acquisition Closing and the other terms and conditions set forth herein, and to the extent requested by the Issuer, to purchase
from the Issuer that number of Common Shares equivalent to its Private Placement Remainder (as defined below) (or such lesser
number of Common Shares as the Issuer may direct) at a purchase price of $10.25 per share, and the Issuer agrees to sell such
Common Shares to Subscriber at such price per share, subject to the Issuer’s right to sell to Subscriber such lesser number
of Common Shares as the Issuer may deem necessary or desirable (the Common Shares to be sold being referred to hereafter as the
“Private Placement Shares” and, together with the total number of Preferred Shares (or alternative securities
of the Issuer with substantially similar economic terms, if required under Section 1(b)) being sold pursuant to Section
1 hereof, the “Acquired Shares”). For the avoidance of doubt, if the Purchase Agreement is terminated in
accordance with its terms prior to the Acquisition Closing, then Subscriber’s obligations to purchase Common Shares under
this Section 2(a)(iv) shall immediately terminate and be extinguished. The subscription for, and issuance of, any Private
Placement Shares pursuant to this Section 2(a)(iv) (such subscription and issuance (if any), together with the Preferred
Subscription, the “Subscriptions”) shall be consummated concurrently with the Closing of the Preferred Subscription.
For purposes hereof, Subscriber’s “Private Placement Remainder” shall mean that number of Common Shares
that is equal to (A) the Backstop Commitment, divided by $10.25, less (B) the number of Market Shares (if any) acquired
or to be acquired pursuant to Section 2(a)(iii) hereof. For the avoidance of doubt, in the event that no Market Shares are
acquired by Subscriber pursuant to Section 2(a)(iii), Subscriber’s obligations under this Section 2(a)(iv)
shall nevertheless continue to apply.

 

(b)       In
consideration for Subscriber’s obligations described in Sections 1 and 2(a) hereof, Subscriber shall be
paid, in immediately available funds, a commitment fee of $2.5 million in cash (the “Commitment Fee”), promptly
following the execution of this Subscription Agreement. Subscriber and the Issuer acknowledge that the Commitment Fee is being
paid by and on behalf of the Issuer by JFL or one of its Affiliates and that in the event that pursuant to the terms of Section
9 hereof, the Commitment Fee less Carrying Costs (as defined below) is required to be paid pursuant to Section 9 hereof,

Issuer shall deliver or shall cause to be delivered to Subscriber and its counsel, on or prior to the Acquisition Closing, such
closing certificates and customary opinion of counsel (which, for the sake of clarity, would exclude any negative assurances),
in each case to the extent reasonably requested by Subscriber, in form and substance reasonably satisfactory to Subscriber and
of the type and form customarily prepared and delivered in a Rule 144A offering for securities substantially similar to the Acquired
Shares;

 

(e)       Each
of the Issuer and Subscriber shall cooperate with the other in connection with the monitoring of and analysis of compliance by
the Issuer and by the Direct Purchasers with the U.S. citizenship requirements set forth in the Jones Act and provide such other
assistance and cooperation as the other may reasonably request to ensure continued compliance by the Issuer and by the Direct Purchasers
with the U.S. citizenship requirements set forth in the Jones Act.

 

The fees and expenses to be incurred by the
Issuer in connection with this Section 7 shall be borne solely by the Issuer. The provisions of this Section 7 shall
at all times be effective and will survive the termination of this Subscription Agreement.

 

8.       Indemnification
of Subscriber.

 

The Issuer shall indemnify and hold harmless
the Subscriber, its affiliates, the directors, officers, employees and agents of the Subscriber and each person, if any, who controls
Subscriber within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all
losses, claims, liabilities, expenses and damages (including any and all investigative, legal and other expenses reasonably incurred
in connection with, and any amount paid in settlement of, any claim, suit, action, proceeding, investigation or inquiry (collectively,
a “Proceeding”) between any of the indemnified parties and any indemnifying parties or between any indemnified party
and any third party, or otherwise, or any claim asserted), to which they, or any of them, may become subject under the Securities
Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses,
claims, liabilities, expenses or damages arise out of or are based on any untrue statement or alleged untrue statement of a material
fact contained in, or the omission or alleged omission of a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances in which such statements were made, not misleading, the Offering Memorandum (to
the extent such statement was derived from the Proxy Statement or SEC Documents); provided, however, that the Issuer
shall not be liable to the extent that such loss, claim, liability, expense or damage is based on any untrue statement or omission
or alleged untrue statement or omission made in reliance on and in conformity with information provided by Subscriber.

 

In addition, in the event that the Subscriber
becomes involved in any capacity in any Proceeding in connection with any matter in any way relating to or referred to in this
Subscription Agreement or arising out of the matters contemplated by this Subscription Agreement, the Issuer will reimburse the
Subscriber for its reasonably incurred and documented legal and other expenses (including the reasonably incurred and documented
costs of any investigation and preparation) as such expenses are incurred by the Subscriber and promptly following request to the
Issuer for reimbursement therefor in connection therewith.

 

    	 	11	 

     

    

 

If indemnification under this Section 8 is
unavailable or insufficient for any reason, the Issuer agrees to contribute to the losses, claims, damages, liabilities and expenses
involved (i) in the proportion appropriate to reflect the relative benefits received by the Issuer , on the one hand, and the Subscriber,
on the other hand, in connection with the matters contemplated by this Subscription Agreement or (ii) if (but only if and to the
extent) the allocation provided for in clause (i) is for any reason held unenforceable, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Issuer, on the one hand, and
the party entitled to contribution, on the other hand, as well as any other relevant equitable considerations. The Issuer agrees
that for the purposes of this paragraph the relative benefits received by the Issuer, on the one hand, and the party entitled to
contribution, on the other hand, in connection with the matters contemplated by this Subscription Agreement shall be deemed to
be in the same proportion that the total value received by the Issuer as a result of or in connection with the matters (whether
or not consummated) bears to the total consideration received by Nomura under the Subscription Agreement. Relative fault shall
be determined by reference to, among other things, whether any alleged untrue statement or omission or any other alleged conduct
relates to information provided by the Issuer or other conduct by the Issuer (or its employees or other agents), on the one hand,
or by the Subscriber, on the other hand.

 

The indemnity and contribution rights hereunder
shall be in addition to any rights that any indemnified party may have at common law or otherwise.

 

9.       Termination.

 

Except for the provisions of Sections 7 through
11, which shall survive any termination hereunder, this Subscription Agreement shall terminate and be void and of no further force
and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of
any party in respect thereof, upon the earlier to occur of (a) such date and time as the Purchase Agreement is terminated
in accordance with its terms, (b) upon the mutual written agreement of each of the parties hereto to terminate this Subscription
Agreement, (c) if any of the conditions to Closing set forth in Section ‎3
of this Subscription Agreement are not satisfied on or prior to the Closing and, as a result thereof, the transactions contemplated
by this Subscription Agreement are not consummated at the Closing or (d) the Termination Date (as defined in the Purchase
Agreement); provided, that nothing herein shall relieve any party from liability for any willful breach hereof prior to
the time of termination, and each party shall be entitled to any remedies at law or in equity to recover losses, liabilities or
damages arising from such breach; provided, further, that upon any termination of this Subscription Agreement pursuant to
this Section 9 arising out of or relating to the failure of Subscriber to perform its obligations under this Subscription
Agreement, then in addition to and without limiting any such rights or remedies of the Issuer or JFL under this Subscription Agreement,
Subscriber shall promptly repay the Commitment Fee less Carrying Costs in cash in immediately available funds to JFL. The Issuer
shall promptly notify Subscriber of the termination of the Purchase Agreement promptly after the termination thereof. For purposes
of this Subscription Agreement, “Carrying Costs” means Subscriber’s documented out-of-pocket costs of carrying
its investment obligations under this Subscription Agreement, which costs are its unsecured funding costs for investment banking
and global markets activities and are used generally and not specific to the investments contemplated hereunder. The Carrying Costs
will be determined in a manner consistent with the practices described and specified by Subscriber to the Issuer and JFL in a written
document or correspondence that specifically references this Section 9 and is delivered by Subscriber to the Issuer and JFL on
the date hereof.

 

Notwithstanding anything herein to the contrary,
the Subscriber may terminate this Subscription Agreement at any time at or prior to the Acquisition Closing, by notice to the Issuer
if since the time of execution of this Subscription Agreement, there shall have occurred and be continuing at the time of
Closing: (A) a long-term suspension or material limitation in trading in securities generally on the NYSE, the NYSE American
or Nasdaq; or (B) a general moratorium on commercial banking activities declared by either federal or New York State authorities
or a material disruption in commercial banking or securities settlement or clearance services in the United States; provided,
that prior to or concurrently with any termination by Subscriber pursuant to clause (A) or (B) above, Subscriber shall have repaid
the Commitment Fee less Carrying Costs in cash in immediately available funds to JFL.

10.       Waiver
of Claims Against Trust. Reference is made to the final prospectus of the Issuer, filed with the SEC (File No. 333-218341)
(the “Prospectus”), and dated as of June 22, 2017. The Subscriber hereby represents and warrants that it understands
that the Issuer has established a trust account (the “Trust Account”) containing the proceeds of its initial
public offering (“IPO”) and from certain private placements occurring simultaneously with the IPO (including
interest accrued from time to time thereon) for the benefit of the Issuer’s public stockholders (including overallotment
shares acquired by the Issuer’s underwriters, the “Public Stockholders”), and has read the provisions
of the Prospectus relating thereto, and that, except as otherwise described in the Prospectus, the Issuer may disburse monies from
the Trust Account only: (a) to the Public Stockholders in the event they elect to redeem their Common Shares in connection with
the consummation of the Issuer’s initial business combination (as such term is used in the Prospectus) (the “Business
Combination”) or in connection with an extension of the deadline to consummate a Business Combination, (b) to the Public
Stockholders if the Issuer fails to consummate a Business Combination within eighteen (18) months after the closing of the IPO,
(c) with respect to any interest earned on the amounts held in the Trust Account, as necessary to pay any taxes or (d) to the Issuer
after or concurrently with the consummation of a Business Combination. For and in consideration of the Issuer’s entering
into discussions with Subscriber regarding the Acquired Shares, and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, Subscriber hereby agrees that it does not now and shall not at any time hereafter
have any right, title, interest or claim of any kind in or to any monies in the Trust Account or distributions therefrom, or make
any claim against, the Trust Account (including any distributions therefrom), regardless of whether such claim arises as a result
of, in connection with or relating in any way to any proposed or actual business relationship between Subscriber and the Issuer,
this Subscription Agreement or any other matter, and regardless of whether such claim arises based on contract, tort, equity or
any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”).
The Subscriber on behalf of itself and its affiliates hereby irrevocably waives any Released Claims that Subscriber or its affiliates
may have against the Trust Account (including any distributions therefrom) now or in the future as a result of, or arising out
of, any negotiations, contracts or agreements with the Issuer (including this Subscription Agreement) or its representatives and
will not seek recourse against the Trust Account (including any distributions therefrom) for any reason whatsoever (including for
an alleged breach of any agreement with the Issuer or its affiliates). The Subscriber agrees and acknowledges that such irrevocable
waiver is material to this Subscription Agreement and specifically relied upon by the Issuer and its affiliates to induce the Issuer
to enter into this Subscription Agreement, and the Subscriber further intends and understands such waiver to be valid, binding
and enforceable under applicable law. To the extent the Subscriber or any of its affiliates commences any action or proceeding
based upon, in connection with, relating to or arising out of any matter relating to the Issuer or its representatives, which proceeding
seeks, in whole or in part, monetary relief against the Issuer or its representatives, the Subscriber hereby acknowledges and agrees
that the Subscriber’s and its affiliates’ sole remedy shall be against funds held outside of the Trust Account and
that such claim shall not permit the Subscriber or its affiliates (or any person claiming on any of their behalves or in lieu of
any of them) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein.
In the event the Subscriber or any of its affiliates commences any action or proceeding based upon, in connection with, relating
to or arising out of any matter relating to the Issuer or its representatives, which proceeding seeks, in whole or in part, relief
against the Trust Account (including any distributions therefrom) or the Public Stockholders, whether in the form of money damages
or injunctive relief, the Issuer and its representatives, as applicable, shall be entitled to recover from the Subscriber and its
affiliates the associated legal fees and costs in connection with any such action, in the event the Issuer or its representatives,
as applicable, prevails in such action or proceeding. This Section 10 will survive any termination or expiration of this Subscription
Agreement and will continue with respect to claims against funds contained in the Trust Account (other than those set aside or
otherwise attributable to distributions made to Public Stockholders) until such time as immediately after a Business Combination
has been consummated; provided that with respect to claims involving distributions made to Public Stockholders and for transaction
expenses paid (including deferred IPO underwriting discount and expenses payable to the Issuer’s underwriters in connection
with the IPO), this Section 10 will survive indefinitely.

of this Subscription Agreement to the same extent as if it were a party hereto, and in no event will the terms of such provisions
be modified, waived or terminated in any manner adverse to JFL or any of its affiliates without the prior written consent of JFL.

 

(h)       This
Subscription Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations

(i)       Except
as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto
and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations,
warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors,
administrators, successors, legal representatives and permitted assigns.

 

(j)       If
any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability
of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue
in full force and effect.

 

(k)       This
Subscription Agreement may be executed in two (2) or more counterparts (including by electronic means), all of which shall be considered
one and the same agreement and shall become effective when signed by each of the parties and delivered to the other parties, it

of (x) the Liquidation Preference, divided by (y) the greater of (1) the applicable Holder Stock Price

this Section 5(b) the Closing Sale Price shall be adjusted proportionally in the event of any stock split, stock dividend,
issuance of rights, options or warrants or other event that would result in an adjustment to the Conversion Rate pursuant to Section 8(e))
plus (ii) the number of shares of the Common Stock that would be issued if any and all accumulated and unpaid dividends were

case of a Fundamental Change in which the Holders of Common Stock will receive only cash consideration, the price to be paid (or
deemed paid) per share of Common Stock in such Fundamental Change transaction and (ii) in all other cases, the average Closing
Sale Price of the Common Stock on the 10 consecutive Trading Days immediately preceding the Effective Date of the Fundamental Change.

 

(c)       The
Fundamental Change Notice shall be given by first-class mail to each record holder of shares of Preferred Stock, at such Holder’s
address as the same appears on the books of the Corporation. Each such notice shall state (i) the anticipated Effective Date
and (ii) that dividends on the Preferred Stock to be converted will cease to accrue on the date immediately preceding the
Effective Date of the Fundamental Change.

 

(d)       Whenever
any provision of this Certificate of Designations requires the Corporation to calculate the Weighted Average Price or Closing Sale
Price for purposes of a Fundamental Change over a span of multiple days, the Board shall make appropriate adjustments to account
for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where
the Record Date of the event occurs, at any time during the period when such Weighted Average Prices or Closing Sale Prices are
to be calculated.

 

6)       Voting.
The shares of Preferred Stock shall have no voting rights except as set forth in this Section 6 or otherwise required by Delaware
law. So long as any shares of Preferred Stock remain Outstanding, unless a greater percentage shall then be required by law, the
Corporation shall not, without the affirmative vote or consent of (a) the Holders of at least 50.1% of the shares of Preferred
Stock Outstanding at the time, voting together as a single class with all series of Parity Stock upon which similar voting rights
have been conferred and are exercisable, given in person or by proxy, either in writing or at a meeting, amend, alter or repeal
the provisions of the Certificate of Incorporation, whether by merger, consolidation or otherwise, so as to materially and adversely
affect any right, preference, privilege or voting powers of the shares of Preferred Stock; provided, however, that
so long as any shares of Preferred Stock remain Outstanding with the terms thereof materially unchanged, such amendment, alteration
or repeal shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers of Holders
of the shares of Preferred Stock and, provided further, that any increase in the amount of authorized preferred stock (including,
without limitation, additional Preferred Stock) or the creation or issuance of any additional shares of Preferred Stock or other
series of preferred stock, or any increase in the amount of authorized shares of such series, in each case of Parity Stock or Junior
Stock, shall not be deemed to materially and adversely affect the rights, preferences, privileges or voting powers of Holders of
shares of Preferred Stock specified herein and (b) for so long as there is any Required Holder, the Required Holder(s), given
in person or by proxy, either in writing or at a meeting, amend, alter or repeal the provisions of the Certificate of Incorporation,
whether by merger, consolidation or otherwise, so as to effect a Material Change.

 

    A-9 

     

    

 

7)       Liquidation
Rights.

 

(a)       In
the event of any liquidation, winding-up or dissolution of the Corporation, whether voluntary or involuntary, each Holder of shares
of Preferred Stock shall be entitled to receive and to be paid out of the assets of the Corporation available for distribution
to its stockholders the Liquidation Preference plus all accumulated and unpaid dividends in respect of the Preferred Stock (whether
or not declared) to the date fixed for liquidation, winding-up or dissolution in preference to the holders of, and before any payment
or distribution is made on, any Junior Stock, including, without limitation, the Common Stock.

 

(b)       Neither
the sale (for cash, shares of stock, securities or other consideration) of all or substantially all the assets or business of the
Corporation (other than in connection with the liquidation, winding-up or dissolution of the Corporation) nor the merger or consolidation
of the Corporation into or with any other Person shall be deemed to be a liquidation, winding-up or dissolution, voluntary or involuntary,
for the purposes of this Section 7.

 

(c)       After
the payment to the Holders of the shares of Preferred Stock of full preferential amounts provided for in this Section 7, the
Holders of Preferred Stock as such shall have no right or claim to any of the remaining assets of the Corporation.

 

(d)       In
the event the assets of the Corporation available for distribution to the Holders of shares of Preferred Stock and holders of shares
of Parity Stock upon any liquidation, winding-up or dissolution of the Corporation, whether voluntary or involuntary, shall be
insufficient to pay in full all amounts to which such Holders are entitled pursuant to this Section 7, no such distribution
shall be made on account of any shares of Parity Stock upon such liquidation, dissolution or winding-up unless proportionate distributable
amounts shall be paid on account of the shares of Preferred Stock, equally and ratably, in proportion to the full distributable
amounts for which holders of all Preferred Stock and of any Parity Stock are entitled upon such liquidation, winding-up or dissolution.

 

8)       Conversion.

 

(a)       Each
Holder of Preferred Stock shall have the right at any time, at its option, to convert, subject to the terms and provisions of this
Section 8 and subject to the limitations set forth in Section 11, any or all of such Holder’s shares of Preferred Stock
into Common Stock at a conversion rate equal to the quotient of (i) the Liquidation Preference; divided by (ii) the
Base Conversion Price (subject to adjustment as provided in this Section 8, the “Conversion Rate”) per
share of Preferred Stock. Notwithstanding the foregoing, but subject to the Conversion Cap, each Holder of Preferred Stock shall
have the right (the “Seven-Year Holder Conversion Right”) at any time after the seven-year anniversary of the
Issue Date, if the then-current Conversion Price exceeds the Weighted Average Price for the Common Stock during any 10 consecutive
Trading Days, at its option by delivery of a Notice of Conversion in accordance with Section 8(b) below no later than 5 Business
Days following such 10th consecutive Trading Day, to convert any or all of such Holder’s shares of Preferred Stock
into, at the Corporation’s sole discretion, either Common Stock, cash or a combination of Common Stock and cash; provided,
that the Corporation shall provide such converting Holder notice of its election within 2 Trading Days of receipt of the Notice
of Conversion; provided further, that in the event the Corporation elects to issue Common Stock for all or a portion of
such conversion, the “Conversion Rate” for such conversion (subject to the limitations set forth in Section 11)
shall mean the quotient of the Liquidation Preference divided by the average Weighted Average Price for the Common Stock
during the 20 consecutive Trading Days commencing on the Trading Day immediately following the Trading Day on which the Corporation
provided such notice. If the Corporation does not elect a settlement method prior to the deadline set forth, the Corporation shall
be deemed to have elected to settle the conversion entirely in Common Stock. Notwithstanding anything to the contrary herein, prior
to the receipt of Shareholder Approval, shares of Preferred Stock shall not be converted pursuant to this Section 8 in the
aggregate into more than 19.99% of the shares of Common Stock outstanding on the Issue Date (subject to appropriate adjustment
in the event of a stock split, stock dividend, combination or other similar recapitalization) (such limitation, the “Conversion
Cap”). Upon conversion of any share of Preferred Stock, the Corporation shall deliver to the converting Holder, in respect
of each share of Preferred Stock being converted, a number of shares of Common Stock equal to the Conversion Rate, together with
a cash payment in lieu of any fractional share of Common Stock in accordance with Section 10, on the second Business Day immediately
following the relevant Conversion Date; provided, that upon any Holder’s election to convert any share or shares of
Preferred Stock pursuant to the second sentence of this Section 8(a) the Corporation shall have the option to deliver the
applicable conversion value (or any portion thereof) in cash in lieu of shares of Common Stock, after providing such Holder at
least 2 Business Days’ prior written notice of its election pursuant to this proviso; provided further, that any such
payment in cash in lieu of shares of Common Stock shall be made in an amount equal to the Liquidation Preference for every whole
share of Preferred Stock so converted; provided further, that if the conversion value consists (x) solely of cash,
then the Corporation shall deliver such cash payment to the Holder no later than 2 Trading Days from the receipt of the Notice
of Conversion or (y) partially of cash, then the Corporation shall deliver such cash payment to the Holder simultaneously
with the delivery of the Common Stock included in the conversion value.

 

    A-10 

     

    

 

(b)       Before
any Holder shall be entitled to convert a share of Preferred Stock as set forth above, such Holder who:

 

(i)       holds
a beneficial interest in a Global Preferred Share must deliver to DTC the appropriate instruction form for conversion pursuant
to DTC’s conversion program (a “Conversion Instruction”) and, if required, pay all transfer or similar
taxes or duties, if any; or

 

(ii)       holds
Preferred Stock in definitive, certificated form must:

 

(A)       manually
sign and deliver an irrevocable notice to the office of the Conversion Agent as set forth in the Form of Certificated Notice of
Conversion (or a facsimile thereof) in the form included in Exhibit A hereto (a “Certificated Notice of Conversion”)
and state in writing therein the number of shares of Preferred Stock to be converted and the name or names (with addresses) in
which such Holder wishes the certificate or certificates for any shares of Common Stock, if any, to be delivered and registered;

 

(B)       surrender
such shares of Preferred Stock, at the office of the Conversion Agent;

 

(C)       if
required, furnish appropriate endorsements and transfer documents; and

 

(D)       if
required, pay all transfer or similar taxes or duties, if any.

 

The Conversion Agent shall notify the Corporation of any pending
conversion pursuant to this Section 8 on the Conversion Date for such conversion. The date on which a Holder complies with
the procedures in this clause (b) is the “Conversion Date.” If more than one share of Preferred Stock shall
be surrendered for conversion at one time by the same Holder, the number of shares of Common Stock to be delivered upon conversion
of such shares of Preferred Stock shall be computed on the basis of the aggregate number of shares of Preferred Stock so surrendered.

 

(c)       With
respect to any conversion of shares of Preferred Stock:

 

(i)       if
there shall have been surrendered certificate or certificates, as the case may be, representing a greater number of shares of Preferred
Stock than the number of shares of Preferred Stock to be converted, the Corporation shall execute and the Registrar shall countersign
and deliver to such Holder or such Holder’s designee, at the expense of the Corporation, a new certificate or certificates,
as the case may be, representing the number of shares of Preferred Stock that shall not have been converted; and

 

(ii)       if
the shares of Preferred Stock converted are held in book-entry form through the facilities of the Depositary, promptly following
the relevant Conversion Date, the Corporation shall cause the Transfer Agent and Registrar to reduce the number of shares of Preferred
Stock represented by the global certificate by making a notation on Schedule I attached to the relevant Global Preferred Share.

 

    A-11 

     

    

 

(d)       Immediately
prior to the close of business on the Conversion Date with respect to a conversion, a converting Holder of Preferred Stock shall
be deemed to be the holder of record of the Common Stock issuable upon conversion of such Holder’s Preferred Stock notwithstanding
that the share register of the Corporation shall then be closed or that certificates representing such Common Stock, if any, shall
not then be actually delivered to such Holder. On the date of any conversion, all rights with respect to the shares of Preferred
Stock so converted, including the rights, if any, to receive notices, shall terminate, excepting only the rights of holders thereof
(i) pursuant to Section 3(f) and (ii) to (A) receive certificates for the number of whole shares of Common
Stock, if any, into which such shares of Preferred Stock have been converted (with a cash payment in lieu of any fractional share
of Common Stock in accordance with Section 10) and (B) exercise the rights to which they are thereafter entitled as holders
of Common Stock, if any.

 

(e)       The
Conversion Rate shall be adjusted, without duplication, upon the occurrence of any of the following events:

 

(i)       If
the Corporation exclusively issues shares of Common Stock as a dividend or distribution on all shares of its Common Stock, or if
the Corporation effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula:

 

 

where,

 

	 	
        CR0
	=	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share combination, as the case may be;
	 	CR1	=	the Conversion Rate in effect immediately after the close of business on the Record Date for such dividend or distribution, or immediately after the open of business on the Effective Date of such share split or share combination, as the case may be;
	 	OS0	=	the number of shares of Common Stock outstanding immediately prior to the close of business on the Record Date for such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share combination, as the case may be; and
	 	OS1	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend or distribution, or such share split or share combination, as the case may be.

 

Any adjustment made under this Section 8(e)(i)
shall become effective immediately after the close of business on the Record Date for such dividend or distribution, or immediately
after the open of business on the Effective Date for such share split or share combination, as the case may be. If any dividend
or distribution of the type described in this Section 8(e)(i) is declared but not so paid or made, the Conversion Rate shall
be immediately readjusted, effective as of the date the Board determines not to pay such dividend or distribution, to the Conversion
Rate that would then be in effect if such dividend or distribution had not been declared.

 

    A-12 

     

    

 

(ii)       If
the Corporation distributes to all or substantially all holders of its Common Stock any rights, options or warrants entitling them,
for a period expiring not more than 60 days immediately following the announcement date of such distribution, to purchase
or subscribe for shares of its Common Stock at a price per share that is less than the average of the Closing Sale Prices of the
Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Date
of such distribution, the Conversion Rate shall be increased based on the following formula:

 

 

where,

 

	 	
        CR0
	=	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such distribution;
	 	CR1	=	the Conversion Rate in effect immediately after the close of business on the Record Date for such distribution;
	 	OS 0	=	the number of shares of Common Stock outstanding immediately prior to the close of business on the Record Date for such distribution;
	 	X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
	 	Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Date of such distribution.

 

Any increase made under this Section 8(e)(ii)
shall be made successively whenever any such rights, options or warrants are distributed and shall become effective immediately
after the close of business on the Record Date for such distribution. To the extent that shares of Common Stock are not delivered
after the expiration of such rights, options or warrants, the Conversion Rate shall be readjusted, effective as of the date of
such expiration, to the Conversion Rate that would then be in effect had the increase with respect to the distribution of such
rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered.
If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased, effective as of the date the
Board determines not to make such distribution, to be the Conversion Rate that would then be in effect if such Record Date for
such distribution had not occurred. If such rights, options or warrants are only exercisable upon the occurrence of certain triggering
events, then the Conversion Rate shall not be adjusted until the triggering events occur.

 

For purposes of this Section 8(e)(ii) in determining
whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such
average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the
Trading Day immediately preceding the Ex-Date of such distribution, and in determining the aggregate offering price of such shares
of Common Stock, there shall be taken into account any consideration received by the Corporation for such rights, options or warrants
and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined
by the Board.

 

    A-13 

     

    

 

(iii)       If
the Corporation distributes shares of its Capital Stock, evidences of its indebtedness or other assets, securities or property
of the Corporation or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all
holders of Common Stock, excluding (a) dividends, distributions or issuances as to which an adjustment was effected pursuant
to Section 8(e)(i) or Section 8(e)(ii), (b) dividends or distributions paid exclusively in cash as to which an adjustment
was effected pursuant to (or a cash amount paid pursuant to the last paragraph of) Section 8(e)(iv) and (c) Spin-Offs
as to which the provisions set forth below in this Section 8(e)(iii) shall apply (any of such shares of Capital Stock, evidences
of indebtedness, other assets, securities or property or rights, options or warrants to acquire Capital Stock or other securities,
the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:

 

 

where,

 

	 	
        CR0
	=	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such distribution;
	 	CR1	=	the Conversion Rate in effect immediately after the close of business on the Record Date for such distribution;
	 	SP0	=	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Date for such distribution; and
	 	FMV	=	the fair market value as of the Record Date for such distribution (as determined by the Board) of the Distributed Property with respect to each outstanding share of the Common Stock.

 

Any increase made under the portion of this Section 8(e)(iii)
above shall become effective immediately after the close of business on the Record Date for such distribution. If such distribution
is not so paid or made, the Conversion Rate shall be decreased, effective as of the date the Board determines not to pay the distribution,
to be the Conversion Rate that would then be in effect if such distribution had not been declared.

 

Notwithstanding the foregoing (but subject to the
limitations set forth in Section 11), if “FMV” (as defined above) is equal to or greater than “SP0”
(as defined above), in lieu of the foregoing increase, each Holder of Preferred Stock shall receive, for each share of Preferred
Stock, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of Distributed Property that
such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate (determined
without regard to the Conversion Cap, Beneficial Ownership Limitation or the Permitted Percentage Limitation) in effect on the
Record Date for the distribution.

 

    A-14 

     

    

 

With respect to an adjustment pursuant to this Section 8(e)(iii)
where there has been a payment of a dividend or other distribution on the Common Stock consisting solely of shares of Capital Stock
of any class or series, or similar equity interests, of or relating to a Subsidiary or other business unit of the Corporation where
such Capital Stock or similar equity interest is, or will be when issued, listed or admitted for trading on a U.S. national
securities exchange (a “Spin-Off”), the Conversion Rate will be increased based on the following formula:

 

 

 

where,

 

	 	
        

        CR0
	=	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Ex-Date for the Spin-Off;
	 	CR1	=	 the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Ex-Date for the Spin-Off;
	 	FMV	=	the average of the Closing Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of Common Stock over the 10 consecutive Trading Day period immediately following, and including, the Ex-Date for the Spin-Off; and
	 	MP0	=	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period immediately following, and including, the Ex-Date for the Spin-Off.

 

The adjustment to the Conversion Rate under the preceding
paragraph shall become effective at the close of business on the 10th Trading Day immediately following, and including,
the Ex-Date for the Spin-Off; provided that, for purposes of determining the Conversion Rate, in respect of any conversion during
the 10 Trading Days following, and including, the Ex-Date of any Spin-Off, references within the portion of this Section 8(e)(iii)
related to Spin-Offs to 10 consecutive Trading Days shall be deemed to be replaced with such lesser number of consecutive Trading
Days as have elapsed between the Ex-Date of such Spin-Off and the relevant Conversion Date.

 

(iv)       If
any cash dividend or distribution is made to all or substantially all holders of the Common Stock, excluding any consideration
payable in connection with a tender or exchange offer made by the Corporation or any of its Subsidiaries, the Conversion Rate shall
be increased based on the following formula:

 

 

where,

 

	 	
        CR0
	=	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such dividend or distribution;
	 	CR1	=	the Conversion Rate in effect immediately after the close of business on the Record Date for such dividend or distribution;
	 	SP0	=	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Date for such dividend or distribution; and
	 	C	=	the amount in cash per share of Common Stock the Corporation distributes to all or substantially all holders of its Common Stock.

 

Any increase pursuant to this Section 8(e)(iv)
shall become effective immediately after the close of business on the Record Date for such dividend or distribution. If such dividend
or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board determines not to pay
or make such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution
had not been declared.

 

Notwithstanding the foregoing, if “C”
(as defined above) is equal to or greater than “SP0“ (as defined above), in lieu of the foregoing increase,
each Holder of Preferred Stock shall receive, for each share of Preferred Stock, at the same time and upon the same terms as holders
of the Common Stock, the amount of cash that such Holder would have received as if such Holder owned a number of shares of Common
Stock equal to the Conversion Rate on the Record Date for such cash dividend or distribution (determined without regard to the
Conversion Cap, Beneficial Ownership Limitation or the Permitted Percentage Limitation).

 

    A-15 

     

    

 

(v)       If
the Corporation or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock
and the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of
the Closing Sale Price of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading
Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion
Rate shall be increased based on the following formula:

 

where,

 

 

	 	
        CR0
	=	the Conversion Rate in effect immediately prior to the close of business on the last Trading Day of the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
	 	CR1	=	the Conversion Rate in effect immediately after the close of business on the last Trading Day of the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
	 	AC	=	the aggregate value of all cash and any other consideration (as determined by the Board) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
	 	OS0	=	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);
	 	OS1	=	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and
	 	SP1	=	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

 

The increase to the Conversion Rate under this Section 8(e)(v)
shall occur at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding
the date such tender or exchange offer expires; provided that, for purposes of determining the Conversion Rate, in respect
of any conversion during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the date that
any such tender or exchange offer expires, references within this Section 8(e)(v) to 10 consecutive Trading Days shall be
deemed to be replaced with such lesser number of consecutive Trading Days as have elapsed between the date such tender or exchange
offer expires and the relevant Conversion Date.

 

In the event that the Corporation or one of its Subsidiaries
is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Corporation or such
Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then
the Conversion Rate shall be readjusted to be such Conversion Rate that would then be in effect if such tender offer or exchange
offer had not been made.

 

    A-16 

     

    

 

(vi)       All
calculations and other determinations under this Section 8(e) shall be made by the Corporation and shall be made to the nearest
one-ten thousandth (1/10,000th) of a share. Notwithstanding anything herein to the contrary, no adjustment under this
Section 8(e) shall be made to the Conversion Rate unless such adjustment would result in a change of at least 1% in the Conversion
Rate then in effect. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next
subsequent adjustment, if any, which, together with any adjustment or adjustments so carried forward, shall amount to a change
of at least 1% in such Conversion Rate; provided, however, that the Corporation shall make such carried-forward adjustments,
regardless of whether the aggregate adjustment is less than 1%, (a) on December 31 of each calendar year, (b) on
the Conversion Date for any conversions of Preferred Stock, (c) upon the occurrence of a Fundamental Change and (d) in
the event that the Corporation exercises its mandatory conversion right pursuant to Section 9. No adjustment to the Conversion
Rate shall be made if it results in a Conversion Price that is less than the par value (if any) of the Common Stock.

 

(vii)       In
addition to those adjustments required by clauses (i), (ii), (iii), (iv) and (v) of this Section 8(e) and to the extent
permitted by applicable law and subject to the applicable rules of the NYSE American, the Corporation may from time to time increase
the Conversion Rate by any amount for a period of at least 20 Business Days or any longer period permitted or required by law if
the increase is irrevocable during that period and the Board determines that such increase would be in the Corporation’s
best interest. In addition, the Corporation may (but is not required to) increase the Conversion Rate to avoid or diminish any
income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares
(or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to any of the preceding two
sentences, the Corporation shall mail to the Holder of each share of Preferred Stock at its last address appearing on the stock
register of the Corporation a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes
effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

 

(viii)       For
purposes of this Section 8(e) the number of shares of Common Stock at any time outstanding shall not include shares held in
the treasury of the Corporation so long as the Corporation does not pay any dividend or make any distribution on shares of Common
Stock held in the treasury of the Corporation, but shall include shares issuable in respect of scrip certificates issued in lieu
of fractions of shares of Common Stock.

 

(f)       Notwithstanding
anything to the contrary in Section 8(e), no adjustment to the Conversion Rate shall be made with respect to any transaction
described in Section 8(e)(i) through Section 8(e)(iv) if the Corporation makes provision for each Holder of the Preferred
Stock to participate in such transaction, at the same time as holders of the Common Stock, without conversion, as if such Holder
held a number of shares of Common Stock equal to the Conversion Rate in effect on the Record Date or Effective Date, as the case
may be, for such transaction, multiplied by the number of shares of Preferred Stock held by such Holder (determined without regard
to the Conversion Cap, the Beneficial Ownership Limitation or the Permitted Percentage Limitation). No adjustment to the Conversion
Rate shall be made with respect to any transaction described in Section 8(e)(v) if the Corporation makes provision for each
Holder of the Preferred Stock to participate in such transaction, at the same time as holders of the Common Stock as if such Holder
held a number of shares of Common Stock equal to the Conversion Rate in effect on the Record Date or Effective Date, as the case
may be, for such transaction, multiplied by the number of shares of Preferred Stock held by such Holder (determined without regard
to the Conversion Cap, the Beneficial Ownership Limitation or the Permitted Percentage Limitation).

 

(g)       Notwithstanding
anything to the contrary herein, no adjustment to the Conversion Rate shall be made pursuant to this Section 8 in respect
of the issuance of any Excluded Securities.

 

(h)       If
the Corporation shall take a record of the holders of its Common Stock for the purpose of entitling them to receive an extraordinary
dividend or other distribution, and shall thereafter (and before the extraordinary dividend or distribution has been paid or delivered
to stockholders) legally abandon its plan to pay or deliver such extraordinary dividend or distribution, then thereafter no adjustment
in the Conversion Rate then in effect shall be required by reason of the taking of such record.

 

    A-17 

     

    

 

(i)       Upon
any increase in the Conversion Rate, the Corporation shall deliver to each Holder, as promptly as practicable, a certificate signed
by an authorized officer of the Corporation, setting forth in reasonable detail the event requiring the adjustment and the method
by which such adjustment was calculated and specifying the increased Conversion Rate then in effect following such adjustment.

 

(j)       In
the case of:

 

(i)       any
recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination),

 

(ii)       any
consolidation, merger or combination involving the Corporation,

 

(iii)       any
sale, lease or other transfer to a third party of the consolidated assets of the Corporation and the Corporation’s Subsidiaries
substantially as an entirety, or

 

(iv)       any
statutory share exchange,

 

as a result of which the Common Stock is converted into, or
exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such transaction
or event, a “Reorganization Event”), then, at and after the effective time of such Reorganization Event, the
right to convert each share of Preferred Stock shall be changed into a right to convert such share into the kind and amount of
shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number
of shares of Common Stock equal to the Conversion Rate immediately prior to such Reorganization Event would have owned or been
entitled to receive upon such Reorganization Event (such stock, securities or other property or assets, the “Reference
Property”). If the Reorganization Event causes the Common Stock to be converted into, or exchanged for, the right to
receive more than a single type of consideration (determined based in part upon any form of stockholder election), then the Reference
Property into which the Preferred Stock will be convertible shall be deemed to be the weighted average of the types and amounts
of consideration received by the holders of Common Stock that affirmatively make such an election. The Corporation shall notify
Holders of such weighted average as soon as practicable after such determination is made. None of the foregoing provisions shall
affect the right of a Holder of Preferred Stock to convert its Preferred Stock into shares of Common Stock as set forth in Section 8(a)
prior to the effective time of such Reorganization Event. Notwithstanding Section 8(e) no adjustment to the Conversion Rate
shall be made for any Reorganization Event to the extent stock, securities or other property or assets become the Reference Property
receivable upon conversion of Preferred Stock.

 

The Corporation shall provide, by amendment hereto effective
upon any such Reorganization Event, for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to
the adjustments provided for in this Section 8. The provisions of this Section 8 shall apply to successive Reorganization
Events.

 

In this Certificate of Designations, if the Common Stock has
been replaced by Reference Property as a result of any such Reorganization Event, references to the Common Stock are intended to
refer to such Reference Property.

 

(k)       The
Corporation shall at all times reserve and keep available for issuance upon the conversion of the Preferred Stock a number of its
authorized but unissued shares of Common Stock equal to the aggregate Liquidation Preference divided by the Conversion Price on
the Issue Date, and shall take all action required to increase the authorized number of shares of Common Stock if at any time there
shall be insufficient unissued shares of Common Stock to permit such reservation or to permit the conversion of all Outstanding
shares of Preferred Stock or the payment or partial payment of dividends declared on Preferred Stock that are payable in Common
Stock.

 

    A-18 

     

    

 

(l)       For
the avoidance of doubt, the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of any such certificate in a name other than that of the holder of the shares of the relevant Preferred
Stock and the Corporation shall not be required to issue or deliver such certificate unless or until the Person or Persons requesting
the issuance or delivery thereof shall have paid to the Corporation the amount of such tax or shall have established to the reasonable
satisfaction of the Corporation that such tax has been paid.

 

(m)       Shares
of Preferred Stock shall immediately and permanently cease to be subject to the Conversion Cap for purposes of this Section 8
and Sections 5 and 9 upon the receipt of Shareholder Approval. For the avoidance of doubt and notwithstanding anything in this
Certificate of Designations to the contrary, the Conversion Cap shall not in any way limit the amounts to accrue or be paid as
dividends. Shares of Preferred Stock not convertible as a result of the Conversion Cap shall remain Outstanding and shall become
convertible by such Holder or another Holder to the extent the Conversion Cap no longer applies. Notwithstanding the foregoing,
the Conversion Cap shall have no effect on any adjustment to the Conversion Rate pursuant to this Section 8.

 

(n)       Notwithstanding
Sections 8(e)(ii) and 8(e)(iii), if the Corporation has a rights plan (including, without limitation, the distribution of
rights pursuant thereto to all holders of the Common Stock) in effect while any shares of Preferred Stock remain Outstanding, Holders
of Preferred Stock will receive, upon conversion of Preferred Stock, in addition to the Common Stock to which a Holder is entitled
(subject to the limitations set forth in Section 11), a corresponding number of rights in accordance with the rights plan. If,
prior to any conversion, such rights have separated from the shares of Common Stock in accordance with the provisions of the applicable
rights plan so that Holders of Preferred Stock would not be entitled to receive any rights in respect of the Common Stock delivered
upon conversion of Preferred Stock, the Conversion Rate will be adjusted at the time of separation, as if the Corporation had distributed
to all holders of its Common Stock, shares of Capital Stock, evidences of indebtedness, assets, securities, property, rights, options
or warrants as described in Section 8(e)(iii) above, subject to readjustment in the event of the expiration, termination or
redemption of such rights.

 

9)       Mandatory
Conversion.

 

(a)       During
the period on or after the 3-year anniversary of the Issue Date but prior to the 5-year anniversary of the Issue Date (the “First
Mandatory Conversion Period”), the Corporation shall have the right, at its option, to give notice of its election to
cause all Outstanding shares of Preferred Stock to be automatically converted into that number of whole shares of Common Stock
for each share of Preferred Stock equal to the Conversion Rate in effect on the Mandatory Conversion Date (subject to the limitations
set forth in Section 11), with cash in lieu of any fractional share pursuant to Section 10. The Corporation may exercise
its right to cause a mandatory conversion pursuant to this Section 9(a) only if the Weighted Average Price of the Common Stock
equals or exceeds 140% (such percentage, the “First Mandatory Conversion Premium”) of the then-current Conversion
Price for at least 20 Trading Days (whether or not consecutive) in a period of 30 consecutive Trading Days, including the last
Trading Day of such 30 Trading Day period, ending on, and including, the Trading Day immediately preceding the Business Day on
which the Corporation issues a press release announcing the mandatory conversion as described in Section 9(d).

 

(b)       During
the period on or after the 5-year anniversary of the Issue Date but prior to the 7-year anniversary of the Issue Date (the “Second
Mandatory Conversion Period”), the Corporation shall have the right, at its option, to give notice of its election to
cause all Outstanding shares of Preferred Stock to be automatically converted into that number of whole shares of Common Stock
for each share of Preferred Stock equal to the Conversion Rate in effect on the Mandatory Conversion Date (subject to the limitations
set forth in Section 11), with cash in lieu of any fractional share pursuant to Section 10. The Corporation may exercise
its right to cause a mandatory conversion pursuant to this Section 9 only if the Weighted Average Price of the Common Stock
equals or exceeds 115% (such percentage, the “Second Mandatory Conversion Premium”) of the then-current Conversion
Price for at least 20 Trading Days (whether or not consecutive) in a period of 30 consecutive Trading Days, including the last
Trading Day of such 30 Trading Day period, ending on, and including, the Trading Day immediately preceding the Business Day on
which the Corporation issues a press release announcing the mandatory conversion as described in Section 9(d).

 

    A-19 

     

    

 

(c)       On
or after the 7-year anniversary of the Issue Date (the “Final Mandatory Conversion Period”), the Corporation
shall have the right, at its option, to give notice of its election to cause all Outstanding shares of Preferred Stock to be automatically
converted into that number of whole shares of Common Stock for each share of Preferred Stock equal to the Conversion Rate in effect
on the Mandatory Conversion Date (subject to the limitations set forth in Section 11), with cash in lieu of any fractional
share pursuant to Section 10. The Corporation may exercise its right to cause a mandatory conversion pursuant to this Section 9(c)
only if the Weighted Average Price of the Common Stock equals or exceeds the Conversion Price for at least 10 consecutive Trading
Days, ending on, and including, the Trading Day immediately preceding the Business Day on which the Corporation issues a press
release announcing the mandatory conversion as described in Section 9(d).

 

(d)       To
exercise any mandatory conversion right described in Sections 9(a) through 9(c), the Corporation must issue a press release
for publication on the Dow Jones News Service or Bloomberg Business News (or if either such service is not available, another broadly
disseminated news or press release service selected by the Corporation) prior to the open of business on the first Trading Day
following any date on which the condition described in any of Sections 9(a) through 9(c) is met, announcing such a mandatory
conversion. The Corporation shall also give notice by mail or by publication (with subsequent prompt notice by mail) to the Holders
of the Preferred Stock (not later than 3 Business Days after the date of the press release) of the mandatory conversion announcing
the Corporation’s intention to convert the Preferred Stock. The conversion date shall be a date selected by the Corporation
(the “Mandatory Conversion Date”) and shall be no fewer than 15 Trading Days, nor more than 20 Trading Days,
after the date on which the Corporation issues the press release described in this Section 9(d). Upon conversion of any Preferred
Stock pursuant to this Section 9, the Corporation shall deliver to the applicable Holder the applicable number of shares of
Common Stock, together with any applicable cash payment in lieu of any fractional share of Common Stock, on the 3rd
Business Day immediately following the relevant Mandatory Conversion Date.

 

(e)       In
addition to any information required by applicable law or regulation, the press release and notice of a mandatory conversion described
in Section 9 shall state, as appropriate: (i) the Mandatory Conversion Date; (ii) the number of shares of Common
Stock to be issued upon conversion of each share of Preferred Stock; and (iii) that dividends on the Preferred Stock to be
converted will cease to accrue on the Mandatory Conversion Date.

 

(f)       On
and after the Mandatory Conversion Date, dividends shall cease to accrue on the Preferred Stock called for a mandatory conversion
pursuant to Section 9 and all rights of Holders of such Preferred Stock shall terminate except for the right to receive the
whole shares of Common Stock issuable upon conversion thereof with a cash payment in lieu of any fractional share of Common Stock
in accordance with Section 10. The full amount of any dividend payment with respect to the Preferred Stock called for a mandatory
conversion pursuant to Section 9 on a date during the period beginning at the close of business on any Dividend Record Date
and ending on the close of business on the corresponding Dividend Payment Date shall be payable on such Dividend Payment Date to
the record holder of such share at the close of business on such Dividend Record Date if such share has been converted after such
Dividend Record Date and prior to such Dividend Payment Date. Except as provided in the immediately preceding sentence with respect
to a mandatory conversion pursuant to Section 9, no payment or adjustment shall be made upon conversion of Preferred Stock
for dividends with respect to the Common Stock issued upon such conversion thereof.

 

(g)       Notwithstanding
anything to the contrary in this Section 9, prior to the receipt of Shareholder Approval, shares of Preferred Stock shall
not be convertible pursuant to Sections 9(a), 9(b) or 9(c) in the aggregate into more than the Conversion Cap.

 

10)       No
Fractional Shares. No fractional shares of Common Stock or securities representing fractional shares of Common Stock shall
be delivered upon conversion, whether voluntary or mandatory, of the Preferred Stock. Instead, the Corporation will make a cash
payment to each Holder that would otherwise be entitled to a fractional share based on the Closing Sale Price of the Common Stock
on the relevant Conversion Date; provided, however, that the Corporation may round such fractional share up to the
next highest whole number of shares in lieu of making such cash payment.

 

    A-20 

     

    

 

11)       Beneficial
Ownership Limitation; Permitted Percentage Limitation; Certain Other Transfer Restrictions.

 

(a)       Notwithstanding
anything herein to the contrary, the Corporation shall not effect any conversion of the Preferred Stock, and a Holder shall not
have the right to convert any portion of the Preferred Stock, in each case to the extent that, after giving effect to such conversion,
such Holder would beneficially own in excess of the Beneficial Ownership Limitation. For purposes of this Section 11(a), beneficial
ownership of a Holder shall be calculated in accordance with Section 16(a) and 16(b) of the Exchange Act and the rules and
regulations promulgated thereunder for purposes of determining whether such Holder is subject to the reporting and liability provisions
of Section 16(a) and 16(b) of the Exchange Act. For purposes of complying with this Section 11(a), the Corporation shall
be entitled to conclusively rely on the information set forth in any Holder’s Notice of Conversion, and each Holder delivering
a Notice of Conversion shall be deemed to represent to the Corporation that such Notice of Conversion does not violate the restrictions
set forth in this paragraph, and the Corporation shall have no obligation to verify or confirm the accuracy of such representation.
Upon the written or oral request of a Holder, the Corporation shall, within 2 Trading Days, confirm orally and in writing to such
Holder the number of shares of Common Stock then outstanding. By written notice to the Corporation, a Holder may from time to time
increase or decrease the Beneficial Ownership Limitation applicable solely to such Holder to any other percentage; provided
that any such increase or decrease will not be effective until the 65th day after such notice is delivered to the
Corporation. The express purpose of this Section 11 is to preclude any Holder’s ownership of any shares of Preferred
Stock from causing such Holder to become subject to the reporting and liability provisions of Section 16(a) and 16(b) of the
Exchange Act, including pursuant to Rule 16a-2 promulgated by the Commission, and this Section 11 shall be interpreted
according to such express purpose. Solely for purposes of this Section 11(a) the term “Holder” shall include all
persons whose beneficial ownership of the Common Stock is aggregated pursuant to Section 13(d)(3) of the Exchange Act or Rule 13d-5
thereunder.

 

(b)       Notwithstanding
anything herein to the contrary, (i) the Corporation shall not effect any conversion of the Preferred Stock, and a Holder shall
not have the right to convert any portion of the Preferred Stock, in each case to the extent that, after giving effect to such
conversion, the number of shares of Common Stock (or any other class or series of the Corporation’s capital stock) beneficially
owned by Non-U.S. Citizens (as defined in the Certificate of Incorporation) in the aggregate would exceed the Permitted Percentage
Limitation, and (ii) the Preferred Stock shall be subject to the limitations on Non-U.S. Citizen (as defined in the Certificate
of Incorporation) ownership set forth in the U.S. Maritime Laws (as defined in the Certificate of Incorporation), and Article V
(Compliance with U.S. Maritime Laws) of the Certificate of Incorporation shall be incorporated by reference herein, mutatis
mutandis, and shall apply as if fully set forth herein, mutatis mutandis, to the ownership
and transfer of Preferred Stock.

 

(c)       
Notwithstanding anything herein to the contrary, no Preferred Stock may be owned by or transferred to any Holder or beneficial
owner that is not a “United States person” within the meaning of Section 7701(a) (30) of the Internal Revenue
Code of 1986, as amended, and the rules and regulations promulgated thereunder, and any transfer made or effected in violation
of this Section 11(c) shall be void ab initio.

 

(d)       Notwithstanding
anything contained herein to the contrary, prior to receipt of Shareholder Approval conversion of the Preferred Stock shall at
all times be limited by the Conversion Cap.

 

12)       Transfer
Agent and Registrar. The duly appointed transfer agent (the “Transfer Agent”) and Registrar (the “Registrar”)
for the Preferred Stock shall be Continental Stock Transfer & Trust Company. The Corporation may, in its sole discretion, remove
the Transfer Agent in accordance with the agreement between the Corporation and the Transfer Agent; provided that the Corporation
shall appoint a successor transfer agent who shall accept such appointment prior to the effectiveness of such removal. For the
avoidance of doubt, the Corporation shall notify the Registrar in writing upon the Corporation’s or any of its Affiliates’
purchases or sales of Preferred Stock.

 

13)       Certificates;
Restrictions on Transfer.

 

(a)       If
physical certificates are issued, then the Corporation shall, upon written request of a Holder, issue certificates in definitive
form representing the shares of Preferred Stock held by such Holder. Every share of Preferred Stock that bears or is required under
this Section 13(a) to bear the legend set forth in Section 13(b) (together with any Common Stock issued upon conversion
of the Preferred Stock that is required to bear the legend set forth in Section 13(b), collectively “Restricted Securities”)
shall be subject to the restrictions on transfer set forth in Section 11 and this Section 13(a) (including the legend
set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Corporation,
and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions
on transfer. As used in this Section 13(a) and in Section 13(b) the term “transfer” encompasses any sale,
pledge, transfer or other disposition whatsoever of any Restricted Security.

 

    A-21 

     

    

 

Until the later of (i) the date on
which such shares of Preferred Stock may be transferred pursuant to a registration statement that has become or been declared effective
under the Securities Act and that continues to be effective at the time of such transfer, or sold pursuant to the exemption from
registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed
by the Corporation in writing with written notice thereof to the Transfer Agent), and (ii) such later date, if any, as may
be required by applicable law (the “Resale Restriction Termination Date”), any certificate evidencing such Preferred
Stock (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion
thereof, which shall bear the legend set forth in Section 13(b) if applicable) shall bear a legend in substantially the following
form:

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE

the checking of such box shall not substitute for satisfaction of any other applicable transfer restrictions).

 

Any share of Preferred Stock (or security
issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their
terms may, upon surrender of such Preferred Stock for exchange to the Registrar, be exchanged for a new share or shares of Preferred

and shall not be assigned a restricted CUSIP number.

 

(b)       Until

shall bear a legend in substantially the following form (unless such Common Stock has been transferred pursuant to a registration
statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of
such transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force

Any such Common Stock as to which such restrictions
on transfer shall have expired in accordance with their terms may, upon surrender of the certificates representing such shares
of Common Stock for exchange in accordance with the procedures of the Transfer Agent, be exchanged for a new certificate or certificates
for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 13(b).

of any other applicable transfer restrictions).

 

(c)       The

14)       Paying
Agent and Conversion Agent.

 

(a)       The
Corporation shall maintain in the United States (i) an office or agency where Preferred Stock may be presented for payment
(the “Paying Agent”) and (ii) an office or agency where, in accordance with the terms hereof, Preferred
Stock may be presented for conversion (the “Conversion Agent”). The Transfer Agent may act as Paying Agent and
Conversion Agent, unless another Paying Agent or Conversion Agent is appointed by the Corporation. The Corporation may appoint
the Registrar, the Paying Agent and the Conversion Agent and may appoint one or more additional paying agents and one or more additional
conversion agents in such other locations as it shall determine. The term “Paying Agent” includes any additional paying
agent and the term “Conversion Agent” includes any additional conversion agent. The Corporation may change any Paying
Agent or Conversion Agent without prior notice to any Holder. The Corporation shall notify the Registrar of the name and address
of any Paying Agent or Conversion Agent appointed by the Corporation. If the Corporation fails to appoint or maintain another entity

Agent, Registrar or Conversion Agent.

 

(b)       Payments
due on the Preferred Stock shall be payable at the office or agency of the Corporation maintained for such purpose in The City
of New York and at any other office or agency maintained by the Corporation for such purpose. Payments of cash shall be payable

by the Registrar at least 15 days prior to the applicable date of payment) to a U.S. dollar account maintained by the
Holder with, a bank located in New York City; provided that at the option of the Corporation, payment of cash dividends
may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Preferred Stock register.

 

    A-24 

     

    

 

15)       Form.

 

(a)       The
Preferred Stock shall be issued in the form of one or more permanent global shares of Preferred Stock in definitive, fully registered
form eligible for book-entry settlement with the global legend (the “Global Shares Legend”) as set forth on
the form of Preferred Stock certificate attached hereto as Exhibit C (each, a “Global Preferred Share”),
which is hereby incorporated in and expressly made part of this Certificate of Designations. The Global Preferred Shares may have
notations, legends or endorsements required by law, stock exchange rules, agreements to which the Corporation is subject, if any,
or usage (provided, that any such notation, legend or endorsement is in a form acceptable to the Corporation). The Global
Preferred Shares shall be deposited on behalf of the Holders represented thereby with the Registrar, at its New York office as
custodian for DTC (the “Depositary”), and registered in the name of the Depositary or a nominee of the Depositary,
duly executed by the Corporation and countersigned and registered by the Registrar as hereinafter provided. The aggregate number
of shares represented by each Global Preferred Share may from time to time be increased or decreased by adjustments made on the
records of the Registrar and the Depositary or its nominee as hereinafter provided.

 

This Section 15(a) shall apply only
to a Global Preferred Share deposited with or on behalf of the Depositary. The Corporation shall execute and the Registrar shall,
in accordance with this Section 15(a) countersign and deliver any Global Preferred Shares that (i) shall be registered
in the name of Cede & Co. or other nominee of the Depositary and (ii) shall be delivered by the Registrar to Cede &
Co. or pursuant to instructions received from Cede & Co. or held by the Registrar as custodian for the Depositary pursuant
to an agreement between the Depositary and the Registrar. Members of, or participants in, the Depositary (“Agent Members”)
shall have no rights under this Certificate of Designations with respect to any Global Preferred Share held on their behalf by
the Depositary or by the Registrar as the custodian of the Depositary, or under such Global Preferred Share, and the Depositary
may be treated by the Corporation, the Registrar and any agent of the Corporation or the Registrar as the absolute owner of such
Global Preferred Share for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Corporation,
the Registrar or any agent of the Corporation or the Registrar from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary
practices of the Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Preferred Share.
The Holder of the Global Preferred Shares may grant proxies or otherwise authorize any Person to take any action that a Holder
is entitled to take pursuant to the Global Preferred Shares, this Certificate of Designations or the Certificate of Incorporation.

 

Owners of beneficial interests in Global
Preferred Shares shall not be entitled to receive physical delivery of certificated shares of Preferred Stock, unless (x) the
Depositary notifies the Corporation that it is unwilling or unable to continue as Depositary for the Global Preferred Shares and
the Corporation does not appoint a qualified replacement for the Depositary within 90 days or (y) the Depositary ceases
to be a “clearing agency” registered under the Exchange Act and the Corporation does not appoint a qualified replacement
for the Depositary within 90 days. In any such case, the Global Preferred Shares shall be exchanged in whole for definitive
stock certificates that are not issued in global form, with the same terms and of an equal aggregate Liquidation Preference, and
such definitive stock certificates shall be registered in the name or names of the Person or Persons specified by the Depositary
in a written instrument to the Registrar.

 

(b)       Signature.
Two Officers permitted by applicable law shall sign each Global Preferred Share for the Corporation, in accordance with the Corporation’s
Bylaws and applicable law, by manual or facsimile signature. If an Officer whose signature is on a Global Preferred Share no longer
holds that office at the time the Registrar countersigned such Global Preferred Share, such Global Preferred Share shall be valid
nevertheless. A Global Preferred Share shall not be valid until an authorized signatory of the Registrar manually countersigns
such Global Preferred Share. Each Global Preferred Share shall be dated the date of its countersignature. The foregoing paragraph
shall likewise apply to any certificate representing shares of Preferred Stock.

 

16)       Other
Provisions.

 

(a)       With
respect to any notice to a Holder of shares of Preferred Stock required to be provided hereunder, neither failure to mail such
notice, nor any defect therein or in the mailing thereof, to any particular Holder shall affect the sufficiency of the notice or
the validity of the proceedings referred to in such notice with respect to the other Holders or affect the legality or validity
of any distribution, rights, warrant, reclassification, consolidation, merger, conveyance, transfer, dissolution, liquidation or
winding-up, or the vote upon any such action. Any notice which was mailed in the manner herein provided shall be conclusively presumed
to have been duly given whether or not the Holder receives the notice.

(b)       Shares
of Preferred Stock that have been issued and reacquired in any manner, including shares of Preferred Stock that are purchased or
exchanged or converted, shall (upon compliance with any applicable provisions of the laws of Delaware) have the status of authorized
but unissued shares of preferred stock of the Corporation undesignated as to series and may be designated or redesignated and issued
or reissued, as the case may be, as part of any series of preferred stock of the Corporation; provided that any issuance
of such shares as Preferred Stock must be in compliance with the terms hereof.

 

(c)       The
shares of Preferred Stock shall be issuable only in whole shares.

 

(d)       If
any applicable law requires the deduction or withholding of any tax from any payment or deemed dividend to a Holder on its Preferred
Stock, the Corporation or an applicable withholding agent may withhold such tax on cash dividends, shares of Preferred Stock, Common
Stock or sale proceeds paid, subsequently paid or credited with respect to such Holder or his successors and assigns.

 

(e)       All
notice periods referred to herein shall commence on the date of the mailing of the applicable notice that initiates such notice
period. Notice to any Holder shall be given to the registered address set forth in the Corporation’s records for such Holder.

 

(f)       To
the extent lawful to do so, the Corporation shall provide the Holders prior written notice of any cash dividend or distribution
to be made to the holders of Common Stock, with such notice to be made no later than the notice thereof provided to all holders
of Common Stock of the Corporation.

 

(g)       Any
payment required to be made hereunder on any day that is not a Business Day shall be made on the next succeeding Business Day and
no interest or dividends on such payment will accrue or accumulate, as the case may be, in respect of such delay.

 

(h)       Holders
of Preferred Stock shall not be entitled to any preemptive rights to acquire additional capital stock of the Corporation.
