To: __________________________ (“Participant”)

I am pleased to advise you that you have been awarded the number of shares of Restricted Stock set forth above under VF Corporation’s 1996 Stock Compensation Plan, as amended (the “1996 Plan”), subject to the terms and conditions set forth in the 1996 Plan and the attached Appendix.  
[If you have not previously accepted and agreed to a Protective Covenants Agreement with VF (or if VF is presenting you a new Protective Covenants Agreement with this Award Certificate), the grant of this Award of Restricted Stock is conditioned upon, and constitutes consideration for, your acceptance of the Protective Covenants Agreement, the form of which has been provided to you together with this Award Certificate.  To meet this condition, you must accept and agree to the Protective Covenants Agreement through the electronic acceptance process for VF employees on Fidelity.com not later than 30 days from the grant communication date.  This electronic acceptance will constitute your signature on the Protective Covenants Agreement. If you choose not to accept the Protective Covenants Agreement by such deadline, this Award will be canceled (however, you will continue to be bound by the most recent Protective Covenants Agreement you accepted and to which you agreed (if any), as neither VF’s presentation nor your rejection of the Protective Covenants Agreement provided with this Award in any way impacts the validity and binding nature of the most recent Protective Covenants Agreement you accepted and to which you agreed-only your acceptance of and agreement to a new Protective Covenants Agreement will modify your existing obligations).
If you have previously accepted and agreed to a Protective Covenants Agreement with VF (and VF is not presenting you with a new Protective Covenants Agreement with this Award Certificate), your acceptance of this Award constitutes your acknowledgment of your obligations under the Protective Covenants Agreement; however, neither VF’s presentation nor your rejection of this Award in any way impacts the validity and binding nature of the most recent Protective Covenants Agreement into which you have entered-only your acceptance of and agreement to a new Protective Covenants Agreement will modify your existing obligations.]

APPENDIX TO

AWARD CERTIFICATE

Terms and Conditions Relating to
Restricted Stock
1. Grant of Restricted Stock.

		
	(a)
	Grant of Restricted Stock under 1996 Plan. Participant has been granted the shares of restricted common stock (the “Restricted Stock”) specified in the Award Certificate under VF Corporation’s (the “Company’s”) 1996 Plan, copies of which have been provided to Participant.  All of the terms, conditions, and other provisions of the 1996 Plan are hereby incorporated by reference into this document.  Capitalized terms used in this document but not defined herein shall have the same meanings as in the 1996 Plan.  If there is any conflict between the provisions of this document and the mandatory provisions of the 1996 Plan, the provisions of the 1996 Plan shall govern.  By accepting the grant of the Restricted Stock, Participant agrees to be bound by all of the terms and provisions of the 1996 Plan (as presently in effect or later amended), the rules and regula-tions under the 1996 Plan adopted from time to time, and the decisions and determinations of the Committee made from time to time.  The Restricted Stock shall be issued promptly hereafter in Participant’s name (and in any event within 30 days after the date of grant) but shall be subject to all provisions of this Award Certificate.

		
	(b)
	Certain Restrictions. One or more stock certificates evidencing the Restricted Stock shall be issued in the name of Participant but shall be held and retained by the Company until the restrictions set forth herein shall have lapsed.  All such stock certificates shall bear the following legend:

“The shares of Common Stock evidenced by this Certificate are subject to the terms and conditions of a Restricted Stock Award Certificate between the registered owner and VF Corporation; such shares are subject to forfeiture under the terms of said Award Certificate; and such shares shall not be sold, transferred, assigned, pledged, encumbered or otherwise alienated or hypothecated except pursuant to the provisions of said Agreement, a copy of which is available from VF Corporation upon request.”
Until the shares of Restricted Stock have become vested in accordance with Paragraph 1(e), the Restricted Stock shall be subject to a risk of forfeiture as provided in the 1996 Plan and this document.  Until vested, such Restricted Stock will be nontransferable, as provided in the 1996 Plan and Paragraph 1(d), and Participant agrees that, upon request of the Company, he or she will deliver to the Company stock powers or other instruments of transfer or assignment, duly endorsed in blank with signature guaranteed, corresponding to each certificate for Restricted Stock or distributions thereon.  If Participant shall fail to provide the Company with any such stock power or other instrument of transfer or assignment, Participant hereby irrevocably appoints the Secretary of the Company as his or her attorney-in-fact to execute and deliver any such power or other instrument which may be necessary to effectuate the transfer of the Restricted Stock (or assignment of distributions thereon) on the books and records of the Company. Participant is subject to the VF Code of Business Conduct and related policies on insider trading.

		
	(c)
	Dividends and Adjustments.   Participant shall be entitled to receive with respect to the Restricted Stock all dividends and distributions payable on Common Stock (including for this purpose any forward stock split) if and to the extent that he is the record owner of such Restricted Stock on any record date for such a dividend or distribution and he has not forfeited such Restricted Stock on or before the payment date for such dividend or distribution, subject to the following terms and conditions:

2

		
	(i)
	Regular Cash Dividends. All cash dividends and distributions payable with respect to the Restricted Stock shall be retained by the Company and reinvested in additional shares of Common Stock to be issued in the name of Participant. Such reinvestment shall occur on the dividend payment date or under a procedure that matches reinvestment of dividends under a dividend reinvestment plan maintained by the Company and open to the participation of shareholders generally.

		
	(ii)
	Common Stock Dividends and Splits.  If the Company declares and pays a dividend or distribution on Common Stock in the form of additional shares of Common Stock, or there occurs a forward split of Common Stock, then the Common Stock issued or delivered as such dividend or distribution or resulting from such stock split will be deemed to be additional Restricted Stock.

		
	(iii)
	Adjustments.  If the Company declares and pays a dividend or distribution on Common Stock that is not a regular cash dividend and not in the form of additional shares of Common Stock, or if there occurs any other event referred to in Article XI of the 1996 Plan, the Company shall retain any such dividend or distribution and the Committee shall adjust the number of shares of Restricted Stock in a manner that will prevent dilution or enlargement of Participant’s rights with respect to the Restricted Stock, in an equitable manner determined by the Committee.  In addition, the Committee may vary the treatment of any dividend or distribution as specified under Section 1(c) (i), (ii) or (iii), in its discretion.

		
	(iv)
	Risk of Forfeiture of Restricted Stock Resulting from Dividends and Adjustments.   Shares of Restricted Stock or other property that directly or indirectly result from dividends or distributions on or adjustments to a share of Restricted Stock shall be subject to the same risk of forfeiture as applies to the granted Restricted Stock.

		
	(v)
	Fractional Shares.  No fractional shares shall be issued under this Agreement.  The Company will determine how to treat any fractional share or amounts that would be deemed invested in a fractional share hereunder.

		
	(d)
	Non-Transferability.  Until the Restricted Stock has become vested, neither Participant nor any beneficiary shall have the right to, directly or indirectly, donate, sell, alienate, assign, transfer, pledge, anticipate, or encumber (except by reason of death) any shares of Restricted Stock, nor shall any such shares of Restricted Stock be subject to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, or garnishment by creditors of Participant or any beneficiary, or to the debts, contracts, liabilities, engagements, or torts of Participant or any beneficiary or transfer by operation of law in the event of bankruptcy or insolvency of Participant or any beneficiary, or any legal process.

		
	(e)
	Vesting and Forfeiture.  The Restricted Stock will vest as follows: 50% of the Restricted Stock will vest on the second anniversary of the Grant Date, and 50% of the Restricted Stock will vest on the fourth anniversary of the Grant Date (each such vesting date being a “Stated Vesting Date”), except as otherwise provided herein, if the Participant continues to be an employee of the Company or any of its subsidiaries or affiliates through the applicable Stated Vesting Date.  If the foregoing condition is met and shares of Restricted Stock become vested, all restrictions on such vested Restricted Stock shall lapse and all shares of Common Stock representing the vested Restricted Stock shall be delivered to Participant free of restrictions.  Except to the extent set forth in this Paragraph 1(e), upon Participant's Termination of Employment prior to an applicable Stated Vesting Date, all unvested Restricted Stock shall be canceled and forfeited and Participant shall have no further rights hereunder. 

		
	(i)
	If Termination of Employment is an involuntary separation by the Company not for Cause, a Pro Rata Portion (as defined below) of the Restricted Stock, less any previously vested shares, shall vest immediately (but will not include any time during which Participant receives Severance Pay), with any unvested Restricted Stock in excess of such Pro Rata Portion canceled and forfeited.

3

		
	(ii)
	 If Termination of Employment is due to a Participant’s death or Disability (as defined below), a Pro Rata Portion (as defined below) of Participant’s Restricted Stock shall vest immediately, with any shares of unvested Restricted Stock in excess of such Pro Rata Portion canceled and forfeited.  

In addition, and notwithstanding anything in this Certificate to the contrary, the Restricted Stock shall be forfeited and shall terminate immediately on the Participant’s date of Termination of Employment for involuntary separation (the date of termination of employment will be determined without giving effect to any period during which severance payments may be made to a Participant) if termination is prior to one year from the grant date.

		
	(f)
	Certain Definitions.  The following definitions apply for purposes of this Agreement:

		
	(i)
	"Cause" means (i), if the Participant has an Employment Agreement defining "Cause," the definition under such Employment Agreement, or (ii), if the Participant has no Employment Agreement defining "Cause," the Participant's gross misconduct, meaning (A) the Participant's willful and continued refusal substantially to perform his or her duties with the Company (other than any such refusal resulting from his or her incapacity due to physical or mental illness), after a demand for substantial performance is delivered to the Participant by the Board of Directors which specifically identifies the manner in which the Board believes that the Participant has refused to perform his or her duties, or (B) the willful engaging by the Participant in gross misconduct materially and demonstrably injurious to the Company.  For purposes of this definition, no act or failure to act on the Participant's part shall be considered "willful" unless done, or omitted to be done, by the Participant not in good faith and without reasonable belief that his or her action or omission was in the best interest of the Company.

		
	(ii)
	"Disability" means (A), if Participant has an Employment Agreement defining "Disability," the definition under such Employment Agreement, or (B), if Participant has no Employment Agreement defining "Disability," Participant's incapacity due to physical or mental illness resulting in Participant's absence from his or her duties with the Company on a full-time basis for 26 consecutive weeks, and, within 30 days after written notice of termination has been given by the Company, Participant has not returned to the full-time performance of his or her duties.

		
	(iii)
	"Pro Rata Portion" means a fraction the numerator of which is the number of days that have elapsed from the Grant Date to the date of Participant's Termination of Employment, not including any severance payment period for involuntary separation, and the denominator of which is the number of days from the Grant Date to the final Stated Vesting Date. 

		
	(iv)
	"Termination of Employment" means termination of Participant's employment with the Company or any of its subsidiaries or affiliates in circumstances in which, immediately thereafter, Participant is not employed by the Company or any of its subsidiaries or affiliates.  Service as a non-employee director shall not be treated as employment for purposes of this Agreement.

		
	(g)
	Compliance with Code Section 409A.  The Restricted Stock is intended to be exempt from Section 409A of the Internal Revenue Code.  The Participant will be subject to federal income taxation no later than the Stated Vesting Date, regardless of any delay in delivery of the share certificate thereafter.

2. Taxes.

		
	(a)
	If Participant properly elects, within 30 days after the Grant Date, to include in gross income for federal income tax purposes an amount equal to the fair market value (as of the Grant Date) of the Restricted Stock, Participant shall make arrangements at the time of such election satisfactory to the Committee to pay to the Company on a timely basis any federal, state or local income taxes required to be withheld with respect to such shares.  If Participant shall fail to make such tax payments as are required, the Company shall, to the extent permitted by law, have the right to deduct from any payment of any kind otherwise due to Participant any federal, state or local taxes of any kind required by law to be withheld with respect to the Restricted Stock.

4

		
	(b)
	If Participant does not make the election described in Paragraph 2(a) above, Participant shall, no later than the date as of which the restrictions referred to in Paragraph 1(e) hereof shall lapse, pay to the Company, or make arrangements satisfactory to the Company for payment of, any federal, state or local taxes of any kind required by law to be withheld with respect to the Restricted Stock, and the Company shall, to the extent permitted by law, have the right to deduct from any payment of any kind otherwise due to Participant any federal, state, or local taxes of any kind required by law to be withheld with respect to the Restricted Stock.   Unless, at least 90 days before the applicable Stated Vesting Date or any earlier applicable vesting date, Participant has made separate arrangements satisfactory to the Company for the payment such mandatory withholding taxes, the Company will withhold from the shares to be delivered upon vesting the number of whole shares having a Fair Market Value equal to the amount of such mandatory withholding taxes, rounded to the nearest whole share.

3. Miscellaneous.

		
	(a)
	Binding Effect; Written Amendments.  The terms and conditions set forth in this document shall be binding upon the heirs, executors, administrators and successors of the parties. The Award Certificate and this document constitute the entire agreement between the parties with respect to the Restricted Stock and supersede any prior agreements or documents with respect thereto.  No amendment, alteration, suspension, discontinuation or termination of this document which may impose any additional obligation upon the Company or materially impair the rights of Participant with respect to the Restricted Stock shall be valid unless in each instance such amendment, alteration, suspension, discontinuation or termination is expressed in a written instrument duly executed in the name and on behalf of the Company and, if Participant’s rights are materially impaired thereby, by Participant.

		
	(b)
	No Promise of Employment.  The Restricted Stock and the granting thereof shall not constitute or be evidence of any agreement or understanding, express or implied, that Participant has a right to continue as an officer, employee or director of the Company or its subsidiaries for any period of time, or at any particular rate of compensation.

		
	(c)
	Governing Law.  The validity, interpretation, construction and performance of this Agreement shall be governed by the laws (but not the law of conflicts of laws) of the State of North Carolina, and applicable federal law.

		
	(d)
	Notices.  Any notice to be given the Company under this Agreement shall be addressed to the Company at its principal executive offices, in care of the Vice President -- Human Resources, and any notice to Participant shall be addressed to Participant at Participant’s address as then appearing in the records of the Company.

		
	(e)
	Shareholder Rights.  Except as otherwise provided in this Agreement, Participant shall have, with respect to all shares of Restricted Stock, all the rights of a shareholder of the Company, including the right to vote the Restricted Stock.

		
	(f)
	Voluntary Participation. Participant’s participation in the Plan is voluntary.  The value of the Restricted Stock is an extraordinary item of compensation.  As such, the Restricted Stock is not part of normal or expected compensation for purposes of calculating any severance, change in control payments, resignation, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments.

4. Restricted Stock subject to Forfeiture Policy for Equity and Incentive Awards in the Event of Restatement of Financial Results.

The Restricted Stock subject to this Award Certificate is subject to the Company’s Forfeiture Policy for Equity and Incentive Awards in the Event of Restatement of Financial Results as in effect at the date of this Award Certificate.  Such Policy imposes

5

conditions that may result in forfeiture of such Restricted Stock or the proceeds to you resulting from such Restricted Stock (a so-called “clawback”) in certain circumstances if the Company’s financial statements are required to be restated as a result of misconduct.

(a)
Availability.

 

(i)
Subject to the terms and conditions of this Agreement, each Lender agrees, severally and not jointly, to make to Borrowers an
advance on the Closing Date in principal amount equal to its First Tranche Term Loan Commitment (the “First Tranche Term

For
the avoidance of doubt, other than the incurrence of the First Tranche Term Loan on the Closing Date, Borrowers are not under
any obligation to request or borrow any other Term Loan from Lenders.

 

(b)
Repayment. Commencing on the Amortization Date, and continuing thereafter on the each Payment Date through the Term Loan
Maturity Date, Borrowers shall make consecutive monthly payments of equal principal and interest, which would fully amortize the
principal amount of the Term Loans and accrued interest thereon by the Term Loan Maturity Date, provided that if the Applicable
Rate is adjusted or the Amortization Date is extended, in each case in accordance with its respective terms, the amortization
schedule and the required monthly installment shall be recalculated based on the adjusted Applicable Rate or, if applicable, the
adjusted number of Payment Dates from the adjusted Amortization Date through the Term Loan Maturity Date, as applicable. Any and
all unpaid Obligations, including principal and accrued and unpaid interest in respect of the Term Loans, the fees pursuant to
the Fee Letter and any other fees and other sums due hereunder, if any, shall be due and payable in full on the Term Loan Maturity
Date. The Term Loans may only be prepaid in accordance with Sections 2.2(c) or (d).

 

(c)
Mandatory Prepayment Upon an Acceleration. If the Loans are accelerated following the occurrence and during the continuance
of an Event of Default, Borrowers shall immediately pay to Lenders, an amount equal to the sum of:

 

(i)
all outstanding principal plus accrued and unpaid interest thereon, plus

 

(ii)
all amounts then due in accordance with the Fee Letter, plus

 

(iii)
all other sums, if any, that shall have become due and payable, including interest at the Default Rate with respect to any past
due amounts.

 

(d)
Permitted Prepayment of Loans. Borrowers shall have the option to prepay all, but not less than all, of the Loans, provided
Borrowers provide written notice to Administrative Agent of its election to prepay the Loans at least thirty (30) days prior to
such prepayment, and pay, on the date of such prepayment, to Lenders, ratably, an amount equal to the sum of:

 

(i)
all outstanding principal plus accrued and unpaid interest thereon, plus

 

(ii)
all amounts then due in accordance with the Fee Letter, plus

 

(iii)
all other sums, if any, that shall have become due and payable, including interest at the Default Rate with respect to any past
due amounts.

 

    	 	2	 

     

    

 

(e)
Conversion at Lenders’ Election.

 

(i)
Conversion Election. Lenders may jointly elect at any time and from time to time after the Closing Date prior to the payment
in full of the Loans to convert any portion of the principal amount of the Loans then outstanding (the “Conversion Amount”)
into shares of Common Stock (“Conversion Shares”) at the Conversion Price pursuant to a Conversion Election
Notice, to be delivered at the direction of Lenders by the Administrative Agent to Parent, provided that the aggregate principal
amount converted to Common Stock in accordance with this Section 2.2(e) shall not exceed $4,000,000. A Conversion Election
Notice, once delivered, shall be irrevocable unless otherwise agreed in writing by Parent. On the third trading day after a Conversion
Election Notice has been duly delivered in accordance with the foregoing, Parent shall credit to each Designated Holder a number
of Conversion Shares equal to (x) the Conversion Amount indicated in the applicable Conversion Election Notice divided by (y)
Conversion Price. For the avoidance of doubt, no premium or penalty shall apply to principal amounts converted pursuant to this
Section 2.2(e).

 

(ii)
Reservation of Shares. Parent shall reserve from its duly authorized capital stock not less than the number of shares of
Common Stock that may be issuable pursuant to this Section 2.2(e). Upon issuance of Conversion Shares pursuant to this
Section 2.2(e), such shares shall be validly issued, fully paid and non-assessable and free from all preemptive or similar
rights, taxes, liens and charges with respect to the issue thereof, and, following the Effective Time, shall be free of any restrictions
on transfer (including any volume limitation) under Federal or state securities laws, pursuant to Rule 144 under the Securities
Act or an effective registration statement and will not contain or be subject to a legend or stop transfer order restricting the
resale or transferability of thereof.

 

(iii)
Rule 144. With a view to making available to Designated Holders the benefits of Rule 144 (or its successor rule) and any
other rule or regulation of the Securities and Exchange Commission (the “SEC”) that may at any time permit
Designated Holders to sell shares of Common Stock issued pursuant to a Conversion Election Notice to the public without registration,
Parent covenants and agrees to: (i) make and keep public information available, as those terms are understood and defined in Rule
144, until six (6) months after such date as all of Conversion Shares issued may be sold without restriction by Designated Holders
pursuant to Rule 144 or any other rule of similar effect; (ii) file with the SEC in a timely manner (or obtain extensions in respect
thereof and file within the applicable grace period) all reports and other documents required of Parent under the 1934 Act; and
(iii) furnish to Designated Holders, upon request, as long as Designated Holders own any shares of Common Stock issued pursuant
to a Conversion Election Notice, such information as may be reasonably requested in order to avail Designated Holders of any rule
or regulation of the SEC that permits the selling of any Conversion Shares issued without registration.

 

(iv)
Registration Rights. In connection with the option to convert in accordance with this Section 2.2(e), Parent hereby
grants to each Designated Holder registration rights on the terms set forth on Schedule 4.

 

(v)
Authorization. For so long as Designated Holders hold any shares of Common Stock issued pursuant to this Section 2.2(e),
Parent shall maintain the Common Stock’s authorization for listing on the NASDAQ Global Select Market, the NASDAQ Global
Market or the NASDAQ Capital Market (or on another national securities exchange) and Parent shall not take any action which could
reasonably be expected to result in the delisting or suspension of the Common Stock on such national securities exchange on which
the Common Stock is listed. Notwithstanding the foregoing, but without limiting Section 7.2, the Parent may enter into
a Change in Control transaction that results in the delisting of the Common Stock from any such national securities exchange,
so long as the consideration received by the holders of the Common Stock in connection therewith is in the form of cash or marketable
securities.

 

(vi)
Limitations on Conversion.

 

(1)
Beneficial Ownership. Notwithstanding anything herein to the contrary, Parent shall not issue a number of Conversion Shares
pursuant to this Section 2.2(e) to the extent that, upon such issuance, the number of shares of Common Stock then beneficially
owned by each Designated Holder and its Affiliates and any group of other persons or entities whose beneficial ownership of Common
Stock would be aggregated with such Designated Holder’s for purposes of Section 13(d) of the Exchange Act would exceed 9.985%
of the total number of shares of Common Stock then issued and outstanding (the “9.985% Cap”); provided that
the 9.985% Cap shall only apply to the extent that the Common Stock is deemed to constitute an “equity security” pursuant
to Rule 13d-1(i) promulgated under the Exchange Act, provided further that Lenders shall have the right, upon 61 days’ prior
written notice to Parent, to waive the 9.985% Cap.

 

    	 	3	 

     

    

 

(2)
Principal Market Regulation. Parent shall not issue a number of Conversion Shares pursuant to this Section 2.2(e),
if the issuance of such shares together with any previously issued Conversion Shares, would result in (A) the issuance of more
than 19.99% of the Common Stock outstanding as of the date of this Agreement or (B) Lenders, together with their Affiliates and
any group of other Persons or entities whose beneficial ownership of Common Stock would be aggregated with such Designated Holder’s
for purposes of Section 13(d) of the Exchange Act, beneficially owning in excess of 19.99% of the then outstanding Common Stock.

 

(3)
Beneficial Ownership Determination. For purposes of this Section 2.2(e), “group” has the meaning set
forth in Section 13(d) of the Exchange Act and applicable regulations of the SEC, and the percentage held by each Designated Holder
shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act. Upon the written request
of Administrative Agent, Parent shall, within two (2) trading days, confirm to the Administrative Agent the number of Shares then
outstanding. As used herein, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act.

 

2.3
Payment of Interest.

 

(a)
Interest Rate. Subject to Section 2.3(b), the outstanding principal amount of the Loans shall accrue interest from
and after its Funding Date, at the Applicable Rate, and Borrowers shall pay such interest monthly in arrears on each Payment Date
commencing on July 1, 2020.

 

(b)
Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, the Applicable Rate shall
be increased by five percentage points (5.0%) above the rate that is otherwise applicable thereto (the “Default Rate”).
Fees and expenses which are required to be paid by Borrowers pursuant to the Loan Documents (including, without limitation, Lender
Expenses) but are not paid when due shall bear interest until paid at a rate equal to the highest rate applicable at such time
to any of the Loans. Payment or acceptance of the increased interest rate provided in this Section 2.3(b) is not a permitted alternative
to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies
pursuant to the Loan Documents. Each Borrower agrees that interest at the Default Rate is a reasonable calculation of Lenders’
lost profits in view of the difficulties and impracticality of determining actual damages resulting from an Event of Default.

 

(c)
Payment; Interest Computation. Interest is payable monthly in arrears on the Payment Date of the following month and shall
be computed on the basis of a 360-day year for the actual number of days elapsed. In computing interest, (i) all payments received
after 4:00 p.m. Eastern Time on any day shall be deemed received at the opening of business on the next Business Day, and (ii)
the date of the making of any Loan shall be included and the date of payment shall be excluded. Changes to the Applicable Rate
based on changes to the Prime Rate, shall be effective as of the date, and to the extent, of such change.

 

(d)
Maximum Interest. Notwithstanding any provision in this Agreement or any other Loan Document, it is the parties’
intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate permissible by law that
a court of competent jurisdiction shall deem applicable hereto (the “Maximum Rate”). If a court of competent
jurisdiction shall finally determine that a Borrower has actually paid to or for the benefit of Lenders an amount of interest
in excess of the amount that would have been payable if all of the Obligations had at all times borne interest at the Maximum
Rate, then such excess interest actually paid by Borrowers shall be applied as follows: first, to the payment of principal outstanding
in respect of the Loans; second, after all principal is repaid, to the payment of accrued interest, third, to the payment of Lender
Expenses and any other Obligations; and fourth, after all Obligations are repaid, the excess (if any) shall be refunded to Borrowers
or paid to whomsoever may be legally entitled thereto, provided that amounts payable to Lenders, shall be paid ratably.

 

(e)
Interest Act (Canada). For the purpose of the Interest Act (Canada), where
in this Agreement a rate of interest is to be calculated on the basis of a year of 360, 365 or 366 days, the yearly rate of interest
to which the rate is equivalent is the rate multiplied by the number of days in the year for which the calculation is made and
divided by 360, 365 or 366, as applicable. Further, in this Agreement all interest shall be calculated using the nominal rate
method and not the effective rate method and the “deemed re investment principle” shall not apply to such calculations.

 

    	 	4	 

     

    

 

(f)
Criminal Code (Canada). If any provision of the Loan Documents would oblige any
Borrower or Guarantor to make any payment of interest or other amount payable to the Administrative Agent or any Lender in an
amount or calculated at a rate which would be prohibited by law or would result in a receipt by that person of “interest”
at a “criminal rate” (as such terms are construed under the Criminal Code (Canada)), then, notwithstanding
such provision, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate
of interest, as the case may be, that would not be so prohibited by applicable law or so result in a receipt by that person of
“interest” at a “criminal rate”, such adjustment to be effected, to the extent necessary (but only to
the extent necessary), as follows: (i) first by reducing the amount or rate of interest required to be paid; and (ii) thereafter,
by reducing any fees, commissions, costs, expenses, premiums and other amounts required to be paid which would constitute interest
for purposes of section 347 of the Criminal Code (Canada). Any amount or rate of interest referred to in this Section
shall be determined in accordance with generally accepted actuarial practices and principles as an effective annual rate of interest
over the term that the applicable Loan remains outstanding on the assumption that any charges, fees or expenses that fall within
the meaning of “interest” (as defined in the Criminal Code (Canada)) shall, if they relate to a specific period
of time, be pro-rated over that period of time and otherwise be pro-rated over the period from the Closing Date to the Term Loan
Maturity Date and, in the event of a dispute, a certificate of a Fellow of the Canadian Institute of Actuaries appointed by Administrative
Agent shall be conclusive for the purposes of such determination.

 

2.4
Fees and Charges. Borrowers shall pay to Administrative Agent, for the ratable benefit of Lenders:

 

(a)
Fees. The fees and charges as and when due in accordance with the Fee Letter; and

 

(b)
Expenses. All Lender Expenses (including reasonable attorneys’ fees and expenses for documentation and negotiation
of this Agreement and the other Loan Documents) incurred through and after the Closing Date, when due (or, if no stated due date,
within two (2) Business Days after demand by Administrative Agent), provided that the deposit in the amount of $50,000 previously
paid shall be applied towards Lender Expenses incurred through the Closing Date (other than legal fees and expenses).

 

2.5
Payments; Application of Payments; Automatic Payment Authorization; Withholding.

 

(a)
All payments to be made by Loan Parties under any Loan Document, including payments of principal and interest and all fees, charges,
expenses, indemnities and reimbursements, shall be made in immediately available funds in Dollars, without setoff, recoupment
or counterclaim, before 4:00 p.m. Eastern Time on the date when due. Payments of principal and/or interest received after 4:00
p.m. Eastern Time are considered received at the opening of business on the next Business Day. When a payment is due on a day
that is not a Business Day, the payment shall be due the next Business Day, and additional fees or interest, as applicable, shall
continue to accrue until paid.

 

(b)
No Loan Party shall have a right to specify the order or the loan accounts to which a Lender shall allocate or apply any payments
made by a Loan Party to or for the benefit of such Lender or otherwise received by such Lender under this Agreement when any such
allocation or application is not expressly specified elsewhere in this Agreement.

 

(c)
Administrative Agent, on behalf of Lenders, may initiate debit entries to any Deposit Accounts as authorized on the Automatic
Payment Authorization for principal and interest payments or any other Obligations when due. These debits shall not constitute
a set-off. If the ACH payment arrangement is terminated for any reason, Loan Parties shall make all payments due hereunder at
the applicable address specified in Section 10, or as otherwise notified by Administrative Agent in writing.

 

(d)
The parties hereto hereby agree to the terms and conditions set forth on Schedule 3 hereto.

 

    	 	5	 

     

    

 

2.6
Promissory Notes. Borrowers agree that: (a) upon written notice by or on behalf of any Lender to Borrowers that a promissory
note or other evidence of indebtedness is requested by such Lender to evidence the Loans and other Obligations owing or payable
to such Lender, Borrowers shall promptly (and in any event within three (3) Business Days of any such request) execute and deliver
to such Lender an appropriate promissory note, in substantially the form attached hereto as Exhibit E, and (b) upon any
Lender’s written request, and in any event within three (3) Business Days of any such request, the Borrowers shall execute
and deliver to such Lender new notes and/or divide the notes in exchange for then existing notes in such smaller amounts or denominations
as such Lender shall specify in its sole and absolute discretion; provided, that the aggregate principal amount of such
new notes shall not exceed the aggregate outstanding principal amount of the applicable Loans made by such Lender; provided,
further, that such promissory notes that are to be replaced shall then be deemed no longer outstanding hereunder and replaced
by such new notes and returned to the Borrowers promptly upon Lender’s receipt of the replacement notes. Regardless whether
or not any such promissory notes are issued, this Agreement shall evidence the Loans and other Obligations owing or payable by
Borrowers to each Lender.

    	 	7	 

     

    

 

(b)
The execution, delivery and performance by each Loan Party of the Loan Documents to which it is a party have been duly authorized,

No order, ruling or decision granted by a securities commission, court of competent jurisdiction or regulatory or administrative
body or other Governmental Authority having jurisdiction is in effect, pending or threatened that restricts any trades in any
securities of Parent including any cease trade orders and, to the knowledge of Parent, no facts or circumstances exist which would
reasonably be expected to give rise to any such order, ruling or decision or other similar claims or investigations. Parent has
authorized share capital consisting of an unlimited number of shares of Common Stock, of which, as of the date hereof, there are
230,648,396 shares of Common Stock issued and outstanding. The currently issued and outstanding shares of Common Stock are listed

date of this Agreement, on the date of such filing), did not contain an untrue statement of a material fact and did not omit to
state any material fact that was required to be stated or necessary to prevent a statement that is made from being false or misleading
in the circumstances in which it was made. Parent has not filed any confidential material change reports which remain confidential
as at the date hereof.

valid and enforceable, and no part of the Intellectual Property which a Loan Party owns, co-owns or purports to own and which
is material to the Loan Parties’ business has been judged by any court to be invalid or unenforceable, in whole or in part.

adverse decision has had or could reasonably be expected to have any Material Adverse Effect.

 

5.5
Financial Statements; Financial Condition. All consolidated and consolidating financial statements for the Loan Parties and
each of their Subsidiaries delivered to Administrative Agent fairly present in all material respects the consolidated and consolidating
financial condition and results of operations of the Loan Parties and each of their Subsidiaries as of the respective dates and
for the respective periods then ended, and there are no material liabilities (including any contingent liabilities) which are

statements submitted to Administrative Agent.

 

5.6

their Subsidiaries, on a consolidated basis, exceeds the fair value of liabilities of the Loan Parties’ and each of their
Subsidiaries, on a consolidated basis; no Loan Party is left with unreasonably small capital after the transactions in this Agreement;
and each Loan Party is able to pay its debts (including trade debts) as they mature.

all Governmental Authorities that are necessary (i) to enter into the Loan Documents and consummate the transactions contemplated
thereby, and (ii) to continue their respective businesses as currently conducted, except (with respect to this clause (ii))
where failure to do so could not reasonably be expected to result in a Material Adverse Effect.

 

5.8
Subsidiaries; Investments. No Loan Party has any Subsidiaries, except as noted on the Perfection Certificate or as disclosed

(or appropriate extensions therefor), and such Loan Party and each of its Subsidiaries has timely paid all foreign, federal, state,
provincial, territorial and local Taxes, assessments, deposits and contributions owed by such Loan Party or such Subsidiary, as

GAAP shall have been made therefor, or (b) if such Taxes, assessments, deposits and contributions do not, individually or in the
aggregate, exceed Ten Thousand Dollars ($10,000). No Loan Party is aware of any claims or adjustments proposed for any prior tax

payable by a Loan Party or any of its Subsidiaries.

 

5.10

obligation exists that would prohibit such Loan Party from pledging the Shares pursuant to this Agreement. There are no subscriptions,

The Shares have been and will be duly authorized and validly issued, and are fully paid and non-assessable. The Shares are not

of no reasonable grounds for the institution of any such proceedings.

securities being referred to herein as “Margin Stock”). None of the proceeds of the Loans or other extensions
of credit under this Agreement have been (or will be) used, directly or indirectly, for the purpose of purchasing or carrying
any Margin Stock, for the purpose of reducing or retiring any Indebtedness which was originally incurred to purchase or carry
any Margin Stock or for any other purpose which might cause any of the Loans or other extensions of credit under this Agreement
to be considered a “purpose credit” within the meaning of Regulation T, U or X of the Federal Reserve Board. Further
and for the avoidance of doubt, no Loan Party or Subsidiary of a Loan Party currently owns any Margin Stock

 

(c)
Neither the making of the Loans hereunder nor Loan Parties’ use of the proceeds thereof will violate the Trading with the

Each Loan Party and its Subsidiaries are in compliance, in all material respects, with the USA Patriot Act and CAML. No part of
the proceeds from the Loans made hereunder has been (or will be) used, directly or indirectly, for any payments to any governmental
official or employee, political party, official of a political party, candidate for political office, or anyone else acting in
an official capacity, in order to obtain, retain or direct business or obtain any improper advantage, in violation of the United

or Prohibited Transaction, as defined in ERISA has occurred or is reasonably expected to occur, and no Loan Party has failed to
meet the minimum funding requirements of ERISA. No Loan Party has violated any applicable environmental laws in any material respect,
maintains any properties or assets which have been designated in any manner pursuant to any environmental protection statute as

marketed or sold, and no Loan Party nor any of its Subsidiary has received any notice
from any applicable Governmental Authority, that such Governmental Authority is conducting an investigation or review of any such

CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER

 

Except
as otherwise expressly provided in any of the Loan Documents, this Agreement and the other Loan Documents shall be governed by,
and construed in accordance with, the laws of the State of New York without regard to principles of conflicts of law. Each Loan
Party hereby submits to the exclusive jurisdiction of the State and Federal courts in New York County, City of New York, New York;
provided, however, that nothing in this Agreement shall be deemed to operate to preclude Administrative Agent or
any Collateral Agent from enforcing a judgment or other court order in favor of Administrative Agent, or any Collateral Agent
or Lender. Each Loan Party expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any
such court, and each Loan Party hereby waives any objection that it may have based upon lack of personal jurisdiction, improper
venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate
by such court. Each Loan Party hereby waives personal service of the summons, complaints, and other process issued in such action
or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed
to such Loan Party at the address set forth in, or subsequently provided by such Loan Party in accordance with, Section 10
and that service so made shall be deemed completed upon the earlier to occur of Loan Parties’ actual receipt thereof
or three (3) Business Days after deposit in the U.S. mails, proper postage prepaid. Each Loan Party hereby expressly waives any
claim to assert that the laws of any other jurisdiction govern this Agreement.

 

TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE PARTIES HERETO EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM
OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING
CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR THE PARTIES TO ENTER INTO THIS AGREEMENT.
NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT OR ANYWHERE ELSE, EACH Loan Party AGREES THAT IT SHALL NOT
SEEK FROM Administrative Agent, or any COLLATERAL agENT OR lender UNDER ANY THEORY OF LIABILITY (INCLUDING ANY THEORY IN TORTS),
ANY SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

 

This
Section 11 shall survive the termination of this Agreement.

12.
GENERAL PROVISIONS

 

12.1
Termination Prior to Term Loan Maturity Date; Survival. All covenants, representations and warranties made in this Agreement
continue in full force until this Agreement has terminated pursuant to its terms and all Obligations (other than contingent indemnification
obligations as to which no claim has been asserted or is known to exist and any other obligations which, by their terms, are to
survive the termination of this Agreement) have been satisfied in full, in cash and all commitments to extend credit pursuant
to this Agreement have terminated. So long as Loan Parties have satisfied the Obligations (other than contingent indemnification
obligations as to which no claim has been asserted or is known to exist and any other obligations which, by their terms, are to
survive the termination of this Agreement), this Agreement and any remaining commitments to extend credit may be terminated prior
to the Term Loan Maturity Date by Loan Parties, by written notice of termination to Lenders. Those obligations that are expressly
specified in this Agreement as surviving this Agreement’s termination shall continue to survive notwithstanding this Agreement’s
termination.

 

12.2
Successors and Assigns.

 

(a)
Successors and Assigns Generally. This Agreement binds and is for the benefit of the successors and permitted assigns of
each party. No Loan Party may assign this Agreement or any rights or obligations under it without Lenders’ prior written
consent (which may be granted or withheld in each Lender’s discretion). Each Lender has the right, without the consent of
or notice to Loan Parties, to sell, transfer, assign, negotiate, or grant participation in all or any part of, or any interest
in, such Lender’s obligations, rights, and benefits under this Agreement and the other Loan Documents (other than the Warrant,
as to which assignment, transfer and other such actions are governed by the terms thereof).

 

(b)
Assignment by Lenders. Each Lender may at any time assign to one or more eligible assignees all or a portion of its rights
and obligations under this Agreement (including all or a portion of its commitment and the Loans at the time owing to it), subject
to any restrictions on such assignment set forth in the other Loan Documents. Each such Lender shall notify the Administrative
Agent of such assignment and deliver to the Administrative Agent a copy of any assignment and assumption agreement entered into
in connection thereto.

 

(c)
Register; Participant Register. Administrative Agent, acting solely for this purpose
as an agent of the Loan Parties, shall maintain at one of its offices in the United States a register for the recordation of the
names and addresses of Lenders, and the Commitments of, and principal amounts (and stated interest) of the Term Loans owing to
each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall
be conclusive absent manifest error, and the Loan Parties, Administrative Agent and Lenders shall treat each Person whose name
is recorded in the Register pursuant to the terms hereof as Lender hereunder for all purposes of this Agreement. The Register
shall be available for inspection by the Loan Parties, any Lender and Collateral Agent at any reasonable time and from time to
time upon reasonable prior notice. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary
agent of the Loan Parties, maintain a register on which it enters the name and address of each participant and the principal amounts
(and stated interest) of each participant’s interest in the Term Loans or other obligations under the Loan Documents (the
“Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of
the Participant Register (including the identity of any participant or any information relating to a participant’s interest
in any commitments, loans or its other obligations under any Loan Document) to any Person except to the extent that such disclosure
is necessary to establish that such commitment, loan or other obligation is in registered form under Section 5f.103-1(c) of the
United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such
Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes
of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, Administrative Agent (in its capacity
as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

 

    	 	21	 

     

    

 

12.3
Indemnification. Each Loan Party agrees to indemnify, defend and hold Administrative Agent, and each Collateral Agent and
Lender and their respective directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing
Lender (each, an “Indemnified Person”) harmless against all obligations, demands, claims, and liabilities (including
such claims, costs, expenses, damages and liabilities based on liability in tort, including strict liability in tort) (collectively,
“Claims”) claimed or asserted by any third party in connection with the transactions contemplated by the Loan
Documents, except for Claims and/or losses to the extent directly caused by such Indemnified Person’s gross negligence or
willful misconduct. This Section 12.3 shall survive until all statutes of limitation with respect to the Claims, losses,
and expenses for which indemnity is given shall have run and, for the avoidance of doubt, shall survive the resignation or replacement
of Administrative Agent or any Collateral Agent. This Section 12.3 shall not apply with respect to Taxes other than any
Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim.

 

12.4
Borrower Liability. Each Borrower hereunder shall be jointly and severally obligated to repay all Loans made hereunder, regardless
of which Borrower actually receives said Loan, as if each Borrower hereunder directly received all Loans. Each Borrower waives
(a) any suretyship defenses available to it under the Code, the PPSA or any other applicable law, and (b) any right to require
any applicable Collateral Agent to: (i) proceed against any Borrower or any other person; (ii) proceed against or exhaust any
security; or (iii) pursue any other remedy. Each applicable Collateral Agent may exercise or not exercise any right or remedy
it has against any Borrower or any security it holds (including the right to foreclose by judicial or non-judicial sale) without
affecting any Borrower’s liability. Notwithstanding any other provision of this Agreement or other related document, each
Borrower irrevocably waives all rights that it may have at law or in equity (including, without limitation, any law subrogating
Borrower to the rights of any Collateral Agent under this Agreement) to seek contribution, indemnification or any other form of
reimbursement from any other Borrower, or any other Person now or hereafter primarily or secondarily liable for any of the Obligations,
for any payment made by such Borrower with respect to the Obligations in connection with this Agreement or otherwise and all rights
that it might have to benefit from, or to participate in, any security for the Obligations as a result of any payment made by
such Borrower with respect to the Obligations in connection with this Agreement or otherwise. Any agreement providing for indemnification,
reimbursement or any other arrangement prohibited under this Section shall be null and void. If any payment is made to a Borrower
in contravention of this Section, such Borrower shall hold such payment in trust for Lenders and such payment shall be promptly
delivered to Administrative Agent, for the ratable benefit of Lenders, for application to the Obligations, whether matured or
unmatured.

 

12.5
Time of Essence. Time is of the essence for the performance of all Obligations in this Agreement.

 

12.6
Severability of Provisions. Each provision of this Agreement is severable from every other provision in determining the enforceability
of any provision.

 

12.7
Correction of Loan Documents. Administrative Agent may correct patent errors and fill in any blanks in the Loan Documents
consistent with the agreement of the parties with ten (10) day prior written notice to Borrower Representative, provided that
if Borrower Representative objects to such correction, such change may be made only pursuant to an Amendment in accordance with
Section 12.9.

 

    	 	22	 

     

    

 

12.8
Amendments in Writing; Waiver; Integration. No purported amendment or modification of any Loan Document, or waiver, discharge
or termination of any obligation under any Loan Document, shall be effective except, pursuant to an agreement in writing by the
parties thereto, and in case of this Agreement, pursuant to an agreement in writing entered into by Loan Parties, Administrative
Agent, the Required Lenders and if applicable, any Collateral Agent party to such Loan Document, provided that Collateral Trustee’s
approval shall not be required for any amendment or supplement that has the effect solely of (i) adding or maintaining Collateral,
securing additional Obligations that are otherwise permitted by the terms of this Agreement to be secured by the Collateral or
preserving, perfecting or establishing the priority of the Liens thereon or the rights of Collateral Trustee therein; (ii) curing
any ambiguity, defect or inconsistency; (iii) providing for the assumption of a Borrower’s or Guarantor’s Obligations
under any Loan Document in the case of a merger or consolidation or sale of all or substantially all of the assets of a Borrower
or Guarantor, as applicable; (iv) making any change that would provide any additional rights or benefits to the Administrative
Agent, any Lender or Collateral Trustee or that does not adversely affect the legal rights under this Agreement or any other Loan
Document of Collateral Trustee; or (v) to the extent the Collateral Trust Agreement does not require Collateral Trustee’s
approval to such amendment or modification. Without limiting the generality of the foregoing, no oral promise or statement, nor
any action, inaction, delay, failure to require performance or course of conduct shall operate as, or evidence, an amendment,
supplement or waiver or have any other effect on any Loan Document. Any waiver granted shall be limited to the specific circumstance
expressly described in it, and shall not apply to any subsequent or other circumstance, whether similar or dissimilar, or give
rise to, or evidence, any obligation or commitment to grant any further waiver. Notwithstanding the foregoing, it is agreed that
any change to the definition of “Designated Holder” or the rights of Designated Holder pursuant to Section 6.15
other than any change to the amount of the permitted investment by Designated Holder, the timing, or other terms and conditions
of a participation by Designated Holder in any equity offering (and any change to this Agreement that would modify the consent
required pursuant to this sentence) shall require the consent of the Collateral Trustee. The Loan Documents represent the entire
agreement about this subject matter and supersede prior negotiations or agreements. All prior agreements, understandings, representations,
warranties, and negotiations among the parties about the subject matter of the Loan Documents merge into the Loan Documents.

 

12.9
Counterparts; Electronic Execution of Documents. This Agreement and any other Loan Documents, except to the extent otherwise
required pursuant to the terms thereof, may be executed in any number of counterparts and by different parties on separate counterparts,
each of which, when executed and delivered, is of the same force and effect as an original, and all taken together, constitute
one Agreement. The words “execution,” “signed,” “signature” and words of like import in any
Loan Document shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall
be of the same legal effect, validity and enforceability as a manually executed signature or the use of a paper-based recordkeeping
systems, as the case may be, to the extent and as provided for in any applicable law, including, without limitation, any state
law based on the Uniform Electronic Transactions Act. Delivery of an executed counterpart of a signature page of any Loan Document
by electronic means including by email delivery of a “.pdf” format data file shall be as effective as delivery of
an original executed counterpart of such Loan Document.

 

12.10
Confidentiality; Publicity.

 

(a)
In handling any confidential information, Administrative Agent and each Lender agree, to exercise the same degree of care that
it exercises for its own proprietary information, but disclosure of information may be made: (a) to its Subsidiaries or Affiliates;
(b) to prospective transferees or purchasers of any interest in the Loans; (c) as required by law, regulation, subpoena, or other
order and in connection with reporting obligations applicable to Administrative Agent, any Collateral Agent or such Lender, including
pursuant to the Exchange Act, (d) to Administrative Agent, or any Collateral Agent or Lender’s regulators or as otherwise
required in connection with any examination or audit; (e) as Administrative Agent, or any Collateral Agent or Lender considers
appropriate in connection with the exercise of remedies with respect to the Obligations; and (f) to third-party service providers
of Administrative Agent, or any Collateral Agent or Lender so long as such prospective transferees or purchasers or service providers
are bound by confidentiality terms not more permissive than the terms hereof. Confidential information does not include information
that is either: (i) in the public domain or in Administrative Agent, or any Collateral Agent or Lender’s possession when
disclosed to Administrative Agent, or such Collateral Agent or Lender, as applicable, or becomes part of the public domain (other
than as a result of its disclosure by Administrative Agent, or such Collateral Agent or Lender or any of the Persons to whom confidential
information was transferred pursuant to this Section 12.10(a) in violation of this Agreement) after disclosure to Administrative
Agent or such Collateral Agent or Lender, as applicable; or (ii) disclosed to Administrative Agent, or such Collateral Agent or
Lender by a third party, if Administrative Agent, or such Collateral Agent or Lender, as applicable, does not know that the third
party is prohibited from disclosing the information. The provisions of this paragraph shall survive the termination of this Agreement.

 

(b)
Neither the Loan Parties nor the Lenders shall publicize or use the other’s name or logo, or hyperlink to the other’
website, describe the relationship of the Loan Parties to the Lenders or the transaction contemplated by this Agreement, in written
and oral presentations, advertising, promotional and marketing materials, client lists, public relations materials or on its web
site (together, the “Publicity Materials”) without such Loan Party or Lender, as applicable, providing prior
written notice to the other that is the subject of the proposed Publicity Materials, together with a draft (or, if Publicity Materials
are not proposed to be delivered in written form, an outline of the content to be included) so as to provide the recipient a reasonable
opportunity to review prior to publication, and each party agrees, in connection with any Publicity Materials proposed by a party
to reasonably consider requested changes or corrections requested by the party that is the subject of such Publicity Materials
in good faith, and upon request, to provide the final form prior to publication or other dissemination.

12.11
Borrower Representative. Each of the Borrowers hereby appoints Borrower Representative to act as its exclusive agent for all
purposes under the Loan Documents (including, without limitation, with respect to all matters related to the borrowing and repayment
of any Loan). Each of the Borrowers acknowledges and agrees that (a) Borrower Representative may execute such documents on behalf
of any Borrower as Borrower Representative deems appropriate in its sole discretion and each Borrower shall be bound by and obligated
by all of the terms of any such document executed by Borrower Representative on its behalf, (b) any notice or other communication
delivered hereunder to Borrower Representative shall be deemed to have been delivered to each Borrower and (c) Administrative
Agent, and any Collateral Agent and Lender shall accept (and shall be permitted to rely on) any document or agreement executed
by Borrower Representative on behalf of Borrowers (or any of them). Borrower must act through the Borrower Representative for
all purposes under this Agreement and the other Loan Documents. Notwithstanding anything contained herein to the contrary, to
the extent any provision in this Agreement requires any Borrower to interact in any manner with Administrative Agent, or any Collateral
Agent or Lender, such Borrower shall do so through Borrower Representative.

 

12.12
Captions. The headings used in this Agreement are for convenience only and shall not affect the interpretation of this Agreement.

 

12.13
Construction of Agreement. The parties mutually acknowledge that they and their attorneys have participated in the preparation
and negotiation of this Agreement. In cases of uncertainty this Agreement shall be construed without regard to which of the parties
caused the uncertainty to exist.

 

12.14
Relationship. The relationship of the parties to this Agreement is determined solely by the provisions of this Agreement.
The parties do not intend to create any agency, partnership, joint venture, trust, fiduciary or other relationship with duties
or incidents different from those of parties to an arm’s-length contract.

 

12.15
Third Parties. Nothing in this Agreement, whether express or implied, is intended to: (a) confer any benefits, rights or remedies
under or by reason of this Agreement on any persons other than the express parties to it and their respective permitted successors
and assigns; (b) relieve or discharge the obligation or liability of any person not an express party to this Agreement; or (c)
give any person not an express party to this Agreement any right of subrogation or action against any party to this Agreement.

 

12.16
Appointment of Administrative Agent.

 

(a)
Each Lender hereby appoints Administrative Agent to act on behalf of Lenders as administrative agent under this Agreement and
the other Loan Documents and appoints CAD Collateral Agent and ISR Collateral Agent to act on behalf of Lenders as collateral
agent pursuant to the CAD Security Documents and the ISR Security Documents, respectively, and to hold and enforce any and all
Liens on the Collateral granted pursuant thereto by the applicable Loan Parties to secure the Obligations (the Administrative
Agent, CAD Collateral Agent and ISR Collateral Agent, collectively, “K2 Agent”). The provisions of this Section
12.16 are solely for the benefit of each K2 Agent and Lenders and no Loan Party nor any other Person shall have any rights
as a third party beneficiary of any of the provisions hereof. In performing its functions and duties under this Agreement, each
K2 Agent does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with
or for any Loan Party or any other Person. Each K2 Agent shall not have any duties or responsibilities except for those expressly
set forth in this Agreement and the other Loan Documents, together with such powers as are reasonably related thereto. The duties
of each K2 Agent shall be mechanical and administrative in nature and no K2 Agent shall have, or be deemed to have, by reason
of this Agreement, any other Loan Document or otherwise a fiduciary relationship in respect of any Lender.

 

(b)
If any K2 Agent shall request instructions from Lenders with respect to any act or action (including failure to act) in connection
with this Agreement or any other Loan Document, then such K2 Agent shall be entitled to refrain from such act or taking such action
unless and until it shall have received instructions from the Required Lenders, and such K2 Agent shall incur no liability to
any Person by reason of so refraining. Each K2 Agent shall be fully justified in failing or refusing to take any action hereunder
or under any other Loan Document for any reason. Without limiting the foregoing, no Lender shall have any right of action whatsoever
against any K2 Agent as a result of such K2 Agent’s acting or refraining from acting hereunder or under any other Loan Document
in accordance with the instructions of Lenders.

 

    	 	24	 

     

    

 

(c)
Each K2 Agent may perform any and all of its duties and exercise its rights and powers hereunder by or through any one or more
sub-agents appointed by such K2 Agent. Each K2 Agent and any such sub-agent may perform any and all of its duties and exercise
its rights and powers by or through their respective related parties. The exculpatory provisions of this Section 12.16
shall apply to any such sub-agent and to the related parties of such K2 Agent and any such sub-agent. No K2 Agent shall be responsible
for the negligence or misconduct of any sub-agent except to the extent that a court of competent jurisdiction determines in a
final and non-appealable judgment that such K2 Agent acted with gross negligence or willful misconduct in the selection of such
sub-agents.

 

(d)
Neither a K2 Agent nor any of its Affiliates nor any of their respective directors, officers, agents or employees shall be liable
for any action taken or omitted to be taken by it or them under or in connection with this Agreement or the other Loan Documents,
except for damages solely caused by its or their own gross negligence or willful misconduct as finally determined by a court of
competent jurisdiction. Without limitation of the generality of the foregoing, each K2 Agent: (i) may consult with legal counsel,
independent chartered accountants and other experts and consultants selected by it and shall not be liable for any action taken
or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants, experts or consultants;
(ii) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties
or representations made in or in connection with this Agreement or the other Loan Documents; (iii) shall not have any duty to
ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or
the other Loan Documents on the part of any Loan Party or to inspect the Collateral (including the books and records) of any Loan
Party; (iv) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency
or value of this Agreement or the other Loan Documents or any other instrument or document furnished pursuant hereto or thereto;
and (v) shall incur no liability under or in respect of this Agreement or the other Loan Documents by acting upon any notice,
consent, certificate or other instrument or writing (which may be by email) believed by it to be genuine and signed or sent by
the proper party or parties.

 

(e)
With respect to its Commitments and Loans hereunder, each K2 Agent shall have the same rights and powers under this Agreement
and the other Loan Documents as any other Lender and may exercise the same as though it were not a K2 Agent; and the term “Lender”
or “Lenders” shall, unless otherwise expressly indicated, include each K2 Agent in its individual capacity (to the
extent it holds any Obligations owing to Lenders or Commitments hereunder). Each K2 Agent and each of its Affiliates may lend
money to, invest in, and generally engage in any kind of business with, any Loan Party, any of their Affiliates and any Person
who may do business with or own securities of any Loan Party or any such Affiliate, all as if such K2 Agent was not a K2 Agent
and without any duty to account therefor to Lenders. Each K2 Agent and its Affiliates may accept fees and other consideration
from any Loan Party for services in connection with this Agreement or otherwise without having to account for the same to Lenders.

 

(f)
Each Lender acknowledges that it has, independently and without reliance upon a K2 Agent or any other Lender, made its own credit
and financial analysis of the Loan Parties and its own decision to enter into this Agreement. Each Lender also acknowledges that
it will, independently and without reliance upon a K2 Agent or any other Lender and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.
Each Lender acknowledges the potential conflict of interest of each other Lender as a result of Lenders holding disproportionate
interests in the Loans, and expressly consents to, and waives any claim based upon, such conflict of interest.

 

(g)
Each Lender agrees to indemnify each K2 Agent (to the extent not reimbursed by Loan Parties and without limiting the obligations
of Loan Parties hereunder), ratably according to its respective Pro Rata Share, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which
may be imposed on, incurred by, or asserted against a K2 Agent in any way relating to or arising out of this Agreement or any
other Loan Document or any action taken or omitted by a K2 Agent in connection therewith; provided, however, that
no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting solely from a K2 Agent’s gross negligence or willful misconduct as finally determined
by a court of competent jurisdiction. Without limiting the foregoing, each Lender agrees to reimburse the applicable K2 Agent
promptly upon demand for its ratable share of any out-of-pocket expenses (including reasonable and documented counsel fees) incurred
by such K2 Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under,
this Agreement and each other Loan Document, to the extent that the applicable K2 Agent is not reimbursed for such expenses by
the Loan Parties.

 

    	 	25	 

     

    

 

(h)
Each K2 Agent may resign at any time by giving not less than thirty (30) days’ prior written notice thereof to Lenders and
Borrowers. Upon any such resignation, Lenders shall have the right to appoint a successor K2 Agent. If no successor K2 Agent shall
have been so appointed by Lenders and shall have accepted such appointment within thirty (30) days after the applicable K2 Agent’s
giving notice of resignation, then such K2 Agent may, on behalf of Lenders, appoint a successor K2 Agent, which shall be a Lender,
if a Lender is willing to accept such appointment, or otherwise shall be a commercial bank or financial institution or a subsidiary
of a commercial bank or financial institution if such commercial bank or financial institution has combined capital of at least
$300,000,000. If no successor K2 Agent has been appointed pursuant to the foregoing, by the 30th day after the date
such notice of resignation was given by the resigning K2 Agent, such resignation shall become effective and Lenders shall thereafter
perform all the duties of the applicable K2 Agent hereunder until such time, if any, as Lenders appoint a successor K2 Agent as
provided above. Upon the acceptance of any appointment as K2 Agent hereunder by a successor K2 Agent, such successor K2 Agent
shall succeed to and become vested with all the rights, powers, privileges and duties of the resigning K2 Agent. Upon the earlier
of the acceptance of any appointment as K2 Agent hereunder by a successor K2 Agent or the effective date of the resigning K2 Agent’s
resignation, the resigning K2 Agent shall be discharged from its duties and obligations under this Agreement and the other Loan
Documents, except that any indemnity, expense reimbursement or other rights in favor of such resigning K2 Agent shall continue.
After any resigning K2 Agent’s resignation hereunder, the provisions of this Section 12.16 shall inure to its benefit
as to any actions taken or omitted to be taken by it while it was K2 Agent under this Agreement and the other Loan Documents.
Notwithstanding the foregoing, as long as K2 HealthVentures LLC is a Lender pursuant to this Agreement, K2 HealthVentures LLC
shall not resign as K2 Agent unless a successor K2 Agent is appointed concurrently with such resignation, which successor K2 Agent
shall have the wherewithal to perform, and shall succeed to and become vested with all the rights, powers, privileges and duties
of the resigning K2 Agent under this Agreement and the other Loan Documents.

 

(i)
In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon
the occurrence and during the continuance of any Event of Default, with the prior written consent of any K2 Agent, each Lender
and each holder of any Obligation is hereby authorized at any time or from time to time, without notice to any Loan Party or to
any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all balances
held by it at any of its offices for the account of any Loan Party or any Subsidiary of a Loan Party (regardless of whether such
balances are then due to such Loan Party or such Subsidiary) and any other properties or assets any time held or owing by that
Lender or that holder to or for the credit or for the account of any Loan Party or any Subsidiary of a Loan Party against and
on account of any of the Obligations which are not paid when due. Any Lender or holder of any Obligation exercising a right to
set off or otherwise receiving any payment on account of the Obligations in excess of its Pro Rata Share thereof in accordance
with the terms of this Agreement relating to the priority of the repayment of the Obligations shall purchase for cash (and the
other Lenders or holders shall sell) such participations in each such other Lender’s or holder’s Pro Rata Share of
the Obligations as would be necessary to cause such Lender to share the amount so set off or otherwise received with each other
Lender or holder in accordance with their respective Pro Rata Shares and in accordance with the terms of this Agreement relating
to the priority of the repayment of the Obligations. Each Loan Party agrees, to the fullest extent permitted by law, that (i)
any Lender or holder may exercise its right to set off with respect to amounts in excess of its Pro Rata Share of the Obligations
and may sell participations in such amount so set off to other Lenders and holders and (ii) any Lender or holders so purchasing
a participation in the Loans made or other Obligations held by other Lenders or holders may exercise all rights of set-off, bankers’
Lien, counterclaim or similar rights with respect to such participation as fully as if such Lender or holder were a direct holder
of the Loans and the other Obligations in the amount of such participation. Notwithstanding the foregoing, if all or any portion
of the set-off amount or payment otherwise received is thereafter recovered from Lender that has exercised the right of set-off,
the purchase of participations by that Lender shall be rescinded and the purchase price restored without interest.

 

(j)
Nothing in this Agreement or the other Loan Documents shall be deemed to require any K2 Agent to advance funds on behalf of any
Lender or to relieve any Lender from its obligation to fulfill its Commitments hereunder or to prejudice any rights that Borrowers
may have against any Lender as a result of any default by such Lender hereunder. To the extent that a K2 Agent advances funds
to Borrowers on behalf of any Lender and is not reimbursed therefor on the same Business Day as such advance is made, such K2
Agent shall be entitled to retain for its account all interest accrued on such advance until reimbursed by the applicable Lender.

 

    	 	26	 

     

    

 

(k)
If a K2 Agent pays an amount to a Lender under this Agreement in the belief or expectation that a related payment has been or
will be received by such K2 Agent from Borrowers and such related payment is not received thereby, then such K2 Agent will be
entitled to recover such amount from such Lender on demand without set-off, counterclaim or deduction of any kind.

 

(l)
If a K2 Agent determines at any time that any amount received thereby under this Agreement shall be returned to Borrowers or paid
to any other Person pursuant to any insolvency law or otherwise, then, notwithstanding any other term or condition of this Agreement
or any other Loan Document, such K2 Agent will not be required to distribute any portion thereof to any Lender. In addition, each
Lender will repay to the applicable K2 Agent on demand any portion of such amount that such has distributed to such Lender, together
with interest at such rate, if any, as such K2 Agent is required to pay to Borrowers or such other Person, without set-off, counterclaim
or deduction of any kind.

 

(m)
Each K2 Agent will use reasonable efforts to provide Lenders with any written notice of Event of Default received by such K2 Agent
from, or delivered by such K2 Agent to, any Loan Party; provided, however, that such K2 Agent shall not be liable
to any Lender for any failure to do so, except to the extent that such failure is attributable solely to such K2 Agent’s
gross negligence or willful misconduct as finally determined by a court of competent jurisdiction.

 

(n)
Anything in this Agreement or any other Loan Document to the contrary notwithstanding, each Lender hereby agrees with each other
Lender and with each K2 Agent that no Lender shall take any action to protect or enforce its rights arising out of this Agreement
or any other Loan Document (including exercising any rights of set-off) without first obtaining the prior written consent of the
Required Lenders, it being the intent of Lenders that any such action to protect or enforce rights under this Agreement and the
other Loan Documents shall be taken in concert and at the direction or with the consent of the applicable K2 Agent at the request
of Required Lenders.

 

13.
GUARANTY

 

13.1
Guaranty. Each Guarantor, who has executed this Agreement as of the date hereof, together with each Loan Party who accedes
to this Agreement as a Guarantor after the date hereof pursuant to Section 6.11 hereby, jointly and severally, unconditionally
and irrevocably, guarantees the prompt and complete payment and performance by Borrowers and the other Loan Parties when due (whether
at the stated maturity, by acceleration or otherwise) of the Obligations. In furtherance of the foregoing, and without limiting
the generality thereof, each Guarantor agrees as follows:

 

(a)
each Guarantor’s liability hereunder shall be the immediate, direct, and primary obligation of such Guarantor and shall
not be contingent upon any exercise or enforcement of any remedy of any Secured Party or that any Secured Party may have against
a Borrower, or any other Guarantor or other Person liable in respect of the Obligations, or all or any portion of the Collateral;
and

 

(b)
Administrative Agent, on behalf of Lenders, may enforce this guaranty notwithstanding the existence of any dispute between any
Secured Party and any Loan Party with respect to the existence of any Event of Default.

 

13.2
Maximum Liability. Anything herein or in any other Loan Document to the contrary notwithstanding, the maximum liability of
each Guarantor shall in no event exceed the amount which can be guaranteed by such Guarantor under applicable federal, state,
provincial or territorial laws relating to the insolvency of debtors (after giving effect to the right of contribution established
in Section 13.5).

 

13.3
Termination. The guaranty pursuant to this Section 13 shall remain in full force and effect until the date the Obligations
have been paid in full in cash, and all commitments to extend credit have been terminated.

 

    	 	27	 

     

    

 

13.4
Unconditional Nature of Guaranty. No payment made by a Borrower, Guarantor, any other guarantor or any other Person or received
or collected by any Secured Party from a Borrower, Guarantor, any other guarantor or any other Person by virtue of any action
or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of
the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which
shall, notwithstanding any such payment (other than any payment made by such Guarantor in respect of the Obligations or any payment
received or collected from such Guarantor in respect of the Obligations), remain liable for the Obligations up to the maximum
liability of such Guarantor hereunder until the date the Obligations are paid in full in cash .

 

13.5
Right of Contribution

 

(a)
If in connection with any payment made by any Guarantor hereunder any rights of contribution arise in favor of such Guarantor
against one or more other Guarantors, such rights of contribution shall be subject to the terms and conditions of Section 13.6.
The provisions of this Section 13.5 shall in no respect limit the obligations and liabilities of any Guarantor pursuant
to the Loan Documents, and each Guarantor shall remain liable for the full amount guaranteed by such Guarantor hereunder.

 

(b)
Notwithstanding any payment made by any Guarantor hereunder or any set-off or application of funds of any Guarantor by any Secured
Party, no Guarantor shall be entitled to be subrogated to any of the rights of any Secured Party against any Loan Party or any
collateral security or guarantee or right of offset held by any Secured Party for the payment of the Obligations, nor shall any
Guarantor seek or be entitled to seek any contribution or reimbursement from any Loan Party in respect of payments made by such
Guarantor hereunder, in each case, until the Obligations are paid in full and all commitments to extend credit have been terminated.
If any amount shall be paid to any Guarantor on account of such subrogation rights at any time prior to the time that the Obligations
are paid in full and all commitments to extend credit have been terminated, such amount shall be held by such Guarantor in trust
for the ratable benefit of the Secured Parties, shall be segregated from other funds of such Guarantor, and shall, forthwith upon
receipt by such Guarantor, be turned over to Administrative Agent in the exact form received by such Guarantor (duly indorsed
by such Guarantor to Administrative Agent, if required), to be applied to the Obligations, irrespective of the occurrence or the
continuance of any Event of Default.

 

13.6
Amendments, etc. with respect to the Obligations. Each Guarantor shall remain obligated hereunder notwithstanding that, without
any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment
of any of the Obligations made by any Secured Party may be rescinded and any of the Obligations continued, and the Obligations,
or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of
offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated,
compromised, waived, surrendered or released by any Secured Party, and this Agreement, the other Loan Documents and any other
documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in
part, in accordance with their respective terms, and any collateral security, guarantee or right of offset at any time held by
any Secured Party for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. No Secured Party
shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations
or for the guarantee pursuant to this Section 13 or any property subject thereto.

 

13.7
Guarantee Absolute and Unconditional; Guarantor Waivers; Guarantor Consent. Each Guarantor waives any and all notice of the
creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by any Secured Party upon
the guaranty contained in this Section 13 or acceptance of this guaranty. The Obligations shall conclusively be deemed
to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon this guaranty. All dealings
between Borrowers, Guarantors and any Secured Party shall be conclusively presumed to have been had or consummated in reliance
upon this guaranty. Each Guarantor further waives:

 

(a)
diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon any Borrower or any of the
other Guarantors with respect to the Obligations;

 

(b)
the defense of the statute of limitations in any action hereunder or for the collection or performance of the Obligations;

 

(c)
any defense arising by reason of any lack of corporate or other authority or any other defense of any Borrower, such Guarantor
or any other Person;

 

    	 	28	 

     

    

 

(d)
any defense based upon errors or omissions by any Secured Party in the administration of the Obligations;

 

(e)
any rights to set-offs and counterclaims;

 

(f)
any defense based upon an election of remedies (including, if available, an election to proceed by nonjudicial foreclosure) which
destroys or impairs the subrogation rights of such Guarantor or the right of such Guarantor to proceed against any Borrower or
any other obligor of the Obligations for reimbursement;

 

(g)
without limiting the generality of the foregoing, to the fullest extent permitted by law, any defenses or benefits that may be
derived from or afforded by applicable law that limit the liability of or exonerate guarantors or sureties, or which may conflict
with the terms of this Agreement; and

 

(h)
without limiting the generality of the foregoing, to the fullest extent permitted by law, any Israeli Loan Party which is a Guarantor
herein, hereby further waive any right or claim under Section 8(1) of the Israeli Guaranty Law, 5727-1967.

 

Each
Guarantor understands and agrees that the guarantee contained in this Section 13 shall be construed as a continuing, absolute
and unconditional guarantee of payment without regard to (i) the validity or enforceability of this Agreement or any other Loan
Document, any of the Obligations or any other collateral security therefor or guaranty or right of offset with respect thereto
at any time or from time to time held by any Secured Party, (ii) any defense, set-off or counterclaim (other than a defense of
payment or performance) which may at any time be available to or be asserted by any Borrower or any other Person against any Secured
Party, or (iii) any other circumstance whatsoever (with or without notice to or knowledge of any Loan Party) which constitutes,
or might be construed to constitute, an equitable or legal discharge of any Borrower for the Obligations, or of such Guarantor
under this guaranty, in bankruptcy or in any other instance, (iv) any Insolvency Proceeding with respect to any Loan Party or
any other Person, (v) any amalgamation, merger, acquisition, consolidation or change in structure of any Loan Party or any other
Person, or any sale, lease, transfer or other disposition of any or all of the assets or Equity Interests of any Loan Party or
any other Person, (vi) any assignment or other transfer, in whole or in part, of Secured Parties’ interests in and rights
under this Agreement or the other Loan Documents, including the right to receive payment of the Obligations, or any assignment
or other transfer, in whole or in part, of any Secured Party’s interests in and to any of the Collateral, (vii) any Secured
Party’s vote, claim, distribution, election, acceptance, action or inaction in any Insolvency Proceeding related to any
of the Obligations, and (viii) any other guaranty, whether by such Guarantor or any other Person, of all or any part of the Obligations
or any other indebtedness, obligations or liabilities of any Guarantor to Secured Parties. When making any demand hereunder or
otherwise pursuing its rights and remedies hereunder against any Guarantor, Secured Parties may, but shall be under no obligation
to, make a similar demand on or otherwise pursue such rights and remedies as it may have against any Loan Party or any other Person
or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto. Any failure by
any Secured Party to make any such demand, to pursue such other rights or remedies or to collect any payments from any Loan Party
or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any
release of any Loan Party or any other Person or any such collateral security, guarantee or right of offset, shall not relieve
any Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express,
implied or available as a matter of law, of any Secured Party against any Guarantor. For the purposes hereof “demand”
shall include the commencement and continuance of any legal proceedings.

 

13.8
Modifications of Obligations. Each Guarantor further unconditionally consents and agrees that, without notice to or further
assent from any Guarantor: (a) the principal amount of the Obligations may be increased or decreased and additional indebtedness
or obligations of a Borrower or any other Persons under the Loan Documents may be incurred, by one or more amendments, modifications,
renewals or extensions of any Loan Document or otherwise; (b) the time, manner, place or terms of any payment under any Loan Document
may be extended or changed, including by an increase or decrease in the interest rate on any Obligation or any fee or other amount
payable under such Loan Document, by an amendment, modification or renewal of any Loan Document or otherwise; (c) the time for
a Borrower’s (or any other Loan Party’s) performance of or compliance with any term, covenant or agreement on its
part to be performed or observed under any Loan Document may be extended, or such performance or compliance waived, or failure
in or departure from such performance or compliance consented to, all in such manner and upon such terms as the applicable Secured
Party may deem proper; (d) in addition to the Collateral, Secured Parties may take and hold other security (legal or equitable)
of any kind, at any time, as collateral for the Obligations, and may, from time to time, in whole or in part, exchange, sell,
surrender, release, subordinate, modify, waive, rescind, compromise or extend such security and may permit or consent to any such
action or the result of any such action, and may apply such security and direct the order or manner of sale thereof; (e) Secured
Parties may discharge or release, in whole or in part, any other Guarantor or any other Loan Party or other Person liable for
the payment and performance of all or any part of the Obligations, and may permit or consent to any such action or any result
of such action, and shall not be obligated to demand or enforce payment upon any of the Collateral, nor shall any Secured Party
be liable to any Guarantor for any failure to collect or enforce payment or performance of the Obligations from any Person or
to realize upon the Collateral, and (f) Secured Parties may request and accept other guaranties of the Obligations and of any
other indebtedness, obligations or liabilities of a Borrower or any other Loan Party to any Secured Party and may, from time to
time, in whole or in part, surrender, release, subordinate, modify, waive, rescind, compromise or extend any such guaranty and
may permit or consent to any such action or the result of any such action; in each case (a) through (f), as the applicable Secured
Parties may deem advisable, and without impairing, abridging, releasing or affecting this Agreement.

 

    	 	29	 

     

    

 

13.9
Reinstatement. The guaranty shall continue to be effective, or be reinstated, as the case may be, if at any time payment,
or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by any Secured Party upon
the insolvency, bankruptcy, dissolution, liquidation or reorganization of a Loan Party, or upon or as a result of the appointment
of a receiver, intervenor or conservator of, or trustee or similar officer for, a Loan Party or any substantial part of its property,
or otherwise, all as though such payments had not been made.

 

13.10
No Waiver by Course of Conduct; Cumulative Remedies. No Secured Party shall by any act (except in writing in accordance with
Section 12.9), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have
acquiesced in any Default or Event of Default, as applicable. No failure to exercise, nor any delay in exercising, on the part
of any Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise
of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right,
power or privilege. A waiver by any Secured Party of any right or remedy hereunder on any one occasion shall not be construed
as a bar to any right or remedy which any Secured Party would otherwise have on any future occasion. The rights and remedies herein
provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided
by law.

 

13.11
Enforcement Expenses; Indemnification. Each Guarantor agrees to pay or reimburse Secured Parties for all its costs and expenses
incurred in collecting against such Guarantor under this guaranty or otherwise enforcing or preserving any rights under this Agreement
and the other Loan Documents to which such Guarantor is a party, including, without limitation, the reasonable fees and disbursements
of counsel provided that no Guarantor shall be liable for indemnification of any expenses under this Section 13.11 to the extent
such expenses arise as a result of the gross negligence or willful misconduct of a Secured Party.

any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding
and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable
law and, if such Tax is an Indemnified Tax, then the sum payable by the Loan Parties shall be increased as necessary so that after
such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable

withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether
or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate
as to the amount of such payment or liability delivered to the Loan Parties by a Lender (with a copy to Administrative Agent),
or by Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

obligation of the Loan Parties to do so), (b) any Taxes attributable to such Lender’s failure to comply with the provisions
of Section 12.2 of the Agreement relating to the maintenance of a Participant Register and (c) any Excluded Taxes attributable
to such Lender, in each case, that are payable or paid by Administrative Agent or any Collateral Agent in connection with any
Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly
or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability
delivered to any Lender by Administrative Agent or any Collateral Agent, as applicable, shall be conclusive absent manifest error.
Each Lender hereby authorizes Administrative Agent and any Collateral Agent to set off and apply any and all amounts at any time
owing to such Lender under any Loan Document or otherwise payable by Administrative Agent or any Collateral Agent, as applicable,
to Lenders from any other source against any amount due to Administrative Agent or any Collateral Agent under this Section
5.

 

6.
Evidence of Payments. As soon as practicable after any payment of Taxes by the Loan Parties to a Governmental Authority pursuant
to the provisions of this Schedule 3, the Loan Parties shall deliver to Administrative Agent the original or a certified
copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or
other evidence of such payment reasonably satisfactory to Administrative Agent.

 

    	 

    	 

    

 

7.
Status of Lenders.

 

(a)
Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan
Document shall deliver to the Loan Parties and Administrative Agent, at the time or times reasonably requested by the Loan Parties
or Administrative Agent, such properly completed and executed documentation reasonably requested by the Loan Parties or Administrative
Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender,
if reasonably requested by the Loan Parties or Administrative Agent, shall deliver such other documentation prescribed by applicable
law or reasonably requested by the Loan Parties or Administrative Agent as will enable the Loan Parties or Administrative Agent
to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding
anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other
than such documentation set forth in Sections 7(b)(i), 7(b)(ii) and 7(b)(iv) of this Schedule 3) shall not be required
if in the applicable Lender’s reasonable judgment such completion, execution or submission would subject such Lender to
any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

 

(b)
Without limiting the generality of the foregoing, in the event that any Loan Party is a U.S. Person,

 

(i)
any Lender that is a U.S. Person shall deliver to such Loan Party and Administrative Agent on or prior to the date on which such
Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of such Loan Party
or Administrative Agent), executed copies of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding
tax;

 

(ii)
any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to such Loan Party and Administrative Agent (in
such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender
under this Agreement (and from time to time thereafter upon the reasonable request of such Loan Party or Administrative Agent),
whichever of the following is applicable:

 

A.
in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect
to payments of interest under any Loan Document, executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E establishing an exemption
from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y)
with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN or IRS Form W-8BEN-E establishing an exemption
from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income”
article of such tax treaty;

 

B.
executed copies of IRS Form W-8ECI;

 

C.
in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Internal
Revenue Code, (x) a certificate, in form and substance reasonably acceptable to such Loan Party and Administrative Agent, to the
effect that such Foreign Lender (or other applicable Person) is not a “bank” within the meaning of Section 881(c)(3)(A)
of the Internal Revenue Code, a “10 percent shareholder” of such Loan Party within the meaning of Section 871(h)(3)(B)
of the Internal Revenue Code, or a “controlled foreign corporation” related to such Loan Party as described in Section
881(c)(3)(C) of the Internal Revenue Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of
IRS Form W-8BEN or IRS Form W-8BEN-E; or

 

D.
to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI,
IRS Form W-8BEN, IRS Form W-8BEN-E, a U.S. Tax Compliance Certificate, IRS Form W-9, and/or other certification documents from
each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect
partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance
Certificate on behalf of each such direct and indirect partner;

 

(iii)
any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to such Loan Party and Administrative Agent (in
such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender
under this Agreement (and from time to time thereafter upon the reasonable request of such Loan Party or Administrative Agent),
executed copies of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal
withholding and Canadian withholding Tax, duly completed, together with such supplementary documentation as may be prescribed
by applicable law to permit such Loan Party or Administrative Agent to determine the withholding or deduction required to be made;
and

 

    	 

    	 

    

 

(iv)
if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such
Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b)
or 1472(b) of the Internal Revenue Code, as applicable), such Lender shall deliver to such Loan Party and Administrative Agent
at the time or times prescribed by law and at such time or times reasonably requested by such Loan Party or Administrative Agent
such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code)
and such additional documentation reasonably requested by such Loan Party or Administrative Agent as may be necessary for such
Loan Party and Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied
with such Lender’s obligations under FATCA or to determine the amount, if any, to deduct and withhold from such payment.
Solely for purposes of this clause (iv), “FATCA” shall include any amendments made to FATCA after the date
of this Agreement.

 

(c)
Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any
respect, it shall update such form or certification or promptly notify the Loan Parties and Administrative Agent in writing of
its legal inability to do so.

 

8.
Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received
a refund of any Taxes as to which it has been indemnified pursuant to the provisions of this Schedule 3 (including by the
payment of additional amounts pursuant to the provisions of this Schedule 3), it shall pay to the indemnifying party an
amount equal to such refund (but only to the extent of indemnity payments made under the provisions of this Schedule 3
with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified
party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund).
Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over
pursuant to this Section 8 (plus any penalties, interest or other charges imposed by the relevant Governmental Authority)
in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything
to the contrary in this Section 8, in no event will the indemnified party be required to pay any amount to an indemnifying
party pursuant to this Section 8 the payment of which would place the indemnified party in a less favorable net after-Tax
position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had
not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax
had never been paid. This Section 8 shall not be construed to require any indemnified party to make available its Tax returns
(or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

 

9.
Increased Costs. If any change in applicable law shall subject any Recipient to any Taxes (other than (A) Indemnified Taxes,
(B) Taxes described in clauses (ii) through (iv) of the definition of Excluded Taxes and (C) Connection Income Taxes) on
its loans, loan principal, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable
thereto, and the result shall be to increase the cost to such Recipient of making, converting to, continuing or maintaining any
Loan or of maintaining its obligation to make any such Loan, or to reduce the amount of any sum received or receivable by such
Recipient (whether of principal, interest or any other amount), then, upon the request of such Recipient, the Loan Parties will
pay to such Recipient such additional amount or amounts as will compensate such Recipient for such additional costs incurred or
reduction suffered.

 

10.
Survival. Each party’s obligations under the provisions of this Schedule 3 shall survive the resignation or replacement
of Administrative Agent or any Collateral Agent or any assignment of rights by, or the replacement of, a Lender, the termination
of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus
to be amended or supplemented by any required Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; (iii) respond promptly to any comments
received from the SEC with respect to the Registration Statement or any amendment thereto and promptly provide the Holders true
and complete copies of all correspondence from and to the SEC relating to the Registration Statement; and (iv) comply in all material
respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities
covered by the Registration Statement during the applicable period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such Prospectus as so supplemented.

 

    	 

    	 

    

 

2.3
Promptly notify the Holders of Registrable Securities (i)(A) when a Prospectus or any Prospectus supplement or post-effective
amendment to the Registration Statement is filed; (B) when the SEC notifies Borrower Representative whether there will be a “review”
of such Registration Statement and whenever the SEC comments in writing on such Registration Statement, and if requested by such
Holders, furnish to them a copy of such comments and Borrower Representative’s responses thereto; and (C) with respect to
the Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request by the SEC
or any other Federal or state governmental authority for amendments or supplements to the Registration Statement or Prospectus
or for additional information; (iii) of the issuance by the SEC of any stop order suspending the effectiveness of the Registration
Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) of the
receipt by Borrower Representative of any notification with respect to the suspension of the qualification or exemption from qualification
of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (v) of the occurrence of any event that makes any statement made in the Registration Statement or Prospectus or any
document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions
to the Registration Statement, Prospectus or other documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to
be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not
misleading.

 

2.4
Use commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the withdrawal of, (i) any order suspending
the effectiveness of the Registration Statement or (ii) any suspension of the qualification (or exemption from qualification)
of any of the Registrable Securities for sale in any U.S. jurisdiction.

 

2.5
If requested by the Administrative Agent on behalf of Designated Holders, (i) promptly incorporate in a Prospectus supplement
or post-effective amendment to the Registration Statement such information as Borrower Representative reasonably agrees should
be included therein and (ii) make all required filings of such Prospectus supplement or such post-effective amendment as soon
as practicable after Borrower Representative has received notification of the matters to be incorporated in such Prospectus supplement
or post-effective amendment.

 

2.6
Furnish to each Holder, without charge and upon request, at least one conformed copy of each Registration Statement and each
amendment thereto, including financial statements and schedules, and, to the extent requested by such Person, all documents incorporated
or deemed to be incorporated therein by reference, and all exhibits (including those previously furnished or incorporated by reference)
promptly after the filing of such documents with the SEC.

 

2.7
Promptly deliver to each Holder, without charge, as many copies of the Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as such Persons may reasonably request; and Borrower Representative hereby
consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with
the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto.

 

2.8
Prior to any public offering of Registrable Securities, use commercially reasonable efforts to register or qualify or cooperate
with the selling Holders in connection with the registration or qualification (or exemption from such registration or qualification)
of such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United
States as any Holder reasonably requests in writing, to keep each such registration or qualification (or exemption therefrom)
effective during the Effectiveness Period and to do any and all other acts or things necessary or advisable to enable the disposition
in such jurisdictions of the Registrable Securities covered by a Registration Statement; provided, however, Borrower
Representative shall in no event be required to (x) qualify to do business in any state where it is not then qualified or (y)
take any action that would subject it to tax or to the general service of process in any such state where it is not then subject,
or (z) comply with state securities or “blue sky” laws of any state for which registration by coordination is unavailable
to Borrower Representative.

 

2.9
Cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities
to be sold pursuant to a Registration Statement, unless such Registrable Securities are not certificated.

 

    	 

    	 

    

 

2.10
Upon the occurrence of any event contemplated by Section 2.3(v), promptly prepare a supplement or amendment, including
a post-effective amendment, to the Registration Statement or a supplement to the related Prospectus or any document incorporated
or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither
the Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which
they were made, not misleading.

 

2.11
Use commercially reasonable efforts to cause all Registrable Securities relating to the Registration Statement to be listed
on the Nasdaq Stock Market or any subsequent securities exchange, quotation system or market, if any, on which similar securities
issued by Borrower Representative are then listed or traded; provided, however, that nothing in the Section 2.11 shall require
Borrow Representative to continue to list its Common Stock on the Nasdaq Stock Market and be a reporting company pursuant to Section
13 of the Exchange Act.

 

2.12
Borrower Representative may require each selling Holder to furnish to Borrower Representative information regarding such Holder
and the distribution of such Registrable Securities as is required by law to be disclosed in the Registration Statement, and Borrower
Representative may exclude from such registration the Registrable Securities of any such Holder who fails to furnish such information
within fifteen (15) days after receiving such request. Each Holder covenants and agrees that (i) it will not sell any Registrable
Securities under the Registration Statement until it has received copies of the Prospectus as then amended or supplemented as
contemplated in Section 2.7 and notice from Borrower Representative that such Registration Statement and any post-effective
amendments thereto have become effective as contemplated by Section 2.3 and (ii) it and its officers, directors or Affiliates,
if any, will comply with the prospectus delivery requirements of the Securities Act as applicable to them in connection with sales
of Registrable Securities pursuant to the Registration Statement. Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from Borrower Representative of the occurrence of any event of the kind described in Sections
2.3(ii), (iii), (iv), (v) or 2.13, such Holder will forthwith discontinue disposition of such Registrable Securities under
the Registration Statement until such Holder’s receipt of the copies of the supplemented Prospectus and/or amended Registration
Statement contemplated by Section 2.10, or until it is advised in writing by Borrower Representative that the use of the
applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement.

 

2.13
If (i) there is material non-public information regarding Borrower Representative which the Board reasonably determines not
to be in Borrower Representative’s best interest to disclose and which Borrower Representative is not otherwise required
to disclose, or (ii) there is a significant business opportunity (including, but not limited to, the acquisition or disposition
of assets (other than in the ordinary course of business) or any merger, consolidation, tender offer or other similar transaction)
available to Borrower Representative which the Board reasonably determines not to be in Borrower Representative’s best interest
to disclose, then Borrower Representative may postpone or suspend filing or effectiveness of a registration statement for a period
not to exceed thirty (30) consecutive days, provided that Borrower Representative may not postpone or suspend its obligation under
this Section 2.13 for more than sixty (60) days in the aggregate during any 12 month period; provided, however,
that no such postponement or suspension shall be permitted for consecutive thirty (30) day periods, arising out of the same set
of facts, circumstances or transactions.

 

2.14
Any legend indicating, directly or indirectly, that the Registrable Securities constitute “restricted securities”
(as such term is defined in Rule 144) stamped on a certificate evidencing the Registrable Securities, and the related stock transfer
instructions and record notations with respect to such Registrable Securities, shall be removed and Borrower Representative shall
approve the issuance of shares without such legend to the holder of such Securities if the Holder thereof provides Borrower Representative
with reasonable assurances that such securities can be sold pursuant to Rule 144. Following the receipt by Borrower Representative
of such assurances, Borrower Representative will, no later than five trading days following the delivery by a holder to Borrower
Representative or Borrower Representative’s transfer agent of a legended certificate representing such securities or a request
to remove the legend from such securities, deliver or cause to be delivered to such Holder shares of such securities that are
free from such restrictive legends.

 

    	 

    	 

    

 

2.15
If a Registration Statement is not effective with respect to all of the Registrable Securities and Borrower Representative
decides to register any of its securities for its own account or for the account of others (if the agreement pursuant to which
such securities are being registered for the account of others so allows), then Borrower Representative will use its commercially
reasonable efforts to include in such registration all or any part of the Registrable Securities requested by Administrative Agent
on behalf of Holders to be included therein (excluding any Registrable Securities previously included in a Registration Statement).
This requirement does not apply to Company registrations on Form S-4 or S-8 or their equivalents (relating to equity securities
to be issued in connection with an acquisition of any entity or business or equity securities issuable in connection with stock
option or other employee benefit plans) or to registration statements that would otherwise not permit the registration of re-sales
of previously issued securities, or to the extent the Conversion Shares do not constitute Registrable Securities. In that event,
if the managing underwriter(s) of the public offering impose a limitation on the number of shares of Common Stock that may be
included in the Registration Statement because, in such underwriter(s)’ judgment, such limitation would be necessary to
effect an orderly public distribution, then Borrower Representative shall include in such registration (i) first, the securities
Borrower Representative proposes to sell, and (ii) second, the Registrable Securities.

 

3
Registration Expenses.

 

All
reasonable fees and expenses incident to the performance of or compliance with this Agreement by Borrower Representative (excluding
underwriters’ discounts and commissions and all fees and expenses of legal counsel, accountants and other advisors for any
Holder except as specifically provided below), except as and to the extent specified in this Section 3, shall be borne
by Borrower Representative whether or not the Registration Statement is filed or becomes effective and whether or not any Registrable
Securities are sold pursuant to the Registration Statement. The fees and expenses referred to in the foregoing sentence shall
include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (A) with respect
to filings required to be made with the Nasdaq Stock Market and each other securities exchange or market on which Registrable
Securities are required hereunder to be listed, (B) with respect to filings required to be made with the Financial Industry Regulatory
Authority and (C) in compliance with state securities or Blue Sky laws), (ii) messenger, telephone and delivery expenses, (iii)
fees and disbursements of counsel for Borrower Representative, (iv) Securities Act liability insurance, if Borrower Representative
so desires such insurance, and (v) fees and expenses of all other Persons retained by Borrower Representative in connection with
the consummation of the transactions contemplated by this Agreement, including, without limitation, Borrower Representative’s
independent public accountants. In addition, Borrower Representative shall be responsible for all of its internal expenses incurred
in connection with the consummation of the transactions contemplated by this Agreement (including, without limitation, all salaries
and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit, the fees and
expenses incurred in connection with the listing of the Registrable Securities on any securities exchange as required hereunder.

 

4
Indemnification.

 

4.1
Indemnification by Borrower Representative. Borrower Representative shall, notwithstanding any termination of this
Agreement, indemnify and hold harmless each Holder, its directors, officers, agents and employees, each Person who controls such
Holder (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers,
agents or employees of such controlling Persons, and the respective successors, assigns, estate and personal representatives of
each of the foregoing, to the fullest extent permitted by applicable law, from and against any and all claims, losses, damages,
liabilities, penalties, judgments, costs (including, without limitation, costs of investigation) and expenses (including, without
limitation, reasonable attorneys’ fees and expenses) (collectively, “Losses”), arising out of third party
claims relating to any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Prospectus,
as supplemented or amended, if applicable, or arising out of or relating to any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus
or supplement thereto, in the light of the circumstances under which they were made) not misleading, except (i) to the extent,
but only to the extent, that such untrue statements or omissions are based upon information regarding such Holder furnished in
writing to Borrower Representative by such Holder expressly for use in the Registration Statement, such Prospectus or such form
of Prospectus or in any amendment or supplement thereto (it being understood that each Holder has approved Annex A hereto for
this purpose); (ii) as a result of the failure of such Holder to deliver a Prospectus, as amended or supplemented, to a purchaser
in connection with an offer or sale; or (iii) in the case of an occurrence of an event of the type specified in Section 2.3(ii)-(v),
the use by a Holder of an outdated or defective Prospectus after Borrower Representative has notified such Holder in writing that
the Prospectus is outdated or defective and prior to the receipt by such Holder of notice that use of the applicable prospectus
may be resumed (and, if applicable, receipt of additional or supplemental filings that are incorporated or deemed to be incorporated
by referenced in such Prospectus or Registration Statement), but only if and to the extent that following such receipt the misstatement
or omission giving rise to such Loss would have been corrected; provided, however, that the indemnity agreement contained in this
Section 4.1 shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the prior
written consent of Borrower Representative, which consent shall not be unreasonably withheld. Borrower Representative shall notify
such Holder promptly of the institution, threat or assertion of any Proceeding of which Borrower Representative is aware in connection
with the transactions contemplated by this Agreement. Such indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of an Indemnified Party (as defined in Section 4.3) and shall survive the transfer of the Registrable
Securities by the Holder.

 

    	 

    	 

    

 

4.2
Indemnification by Holders. Each Holder and its permitted assignees shall, severally and not jointly, indemnify and
hold harmless Borrower Representative, its directors, officers, agents and employees, each Person who controls Borrower Representative
(within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents
or employees of such controlling Persons, and the respective successors, assigns, estate and personal representatives of each
of the foregoing, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of
or relating to any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Prospectus,
as supplemented or amended, if applicable, or arising out of or relating to any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or supplement thereto,
in the light of the circumstances under which they were made) not misleading, to the extent, but only to the extent, that such
untrue statement or omission is contained in or omitted from any information regarding such Holder furnished in writing to Borrower
Representative by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such
Holder’s proposed method of distribution of Registrable Securities and was furnished in writing by such Holder expressly
for use therein (it being understood that each Holder has approved Annex A hereto for this purpose). Notwithstanding anything
to the contrary contained herein, in no event shall the liability of any Person under this Section 4.2 exceed the net proceeds
to such Person as a result of the sale of Registrable Securities pursuant to a Registration Statement in connection with which
the untrue or alleged untrue statement or material omission was provided.

 

4.3
Conduct of Indemnification Proceedings.

 

(a)
If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”),
such Indemnified Party promptly shall notify the Person from whom indemnity is sought (the “Indemnifying Party”)
in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory
to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that
the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities
pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction
(which determination is not subject to appeal or further review) that such failure shall have proximately and materially adversely
prejudiced the Indemnifying Party.

 

(b)
An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the
Indemnifying Party has agreed in writing to pay such fees and expenses; or (2) the Indemnifying Party shall have failed promptly
to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding;
or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the
Indemnifying Party, and such Indemnified Party shall have been advised by counsel (which shall be reasonably acceptable to the
Indemnifying Party) that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party
and the Indemnifying Party (in which case, the Indemnifying Party shall be responsible for reasonable fees and expenses of no
more than one counsel for the Indemnified Parties). The Indemnifying Party shall not be liable for any settlement of any such
Proceeding effected without its written consent, which consent shall not be unreasonably withheld or delayed. No Indemnifying
Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect
of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party
from all liability on claims that are the subject matter of such Proceeding.

 

    	 

    	 

    

 

(c)
All out-of-pocket fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in
connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be
paid to the Indemnified Party, as incurred, within twenty (20) Business Days of written notice thereof to the Indemnifying Party
(regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided,
that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent
it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder).

 

4.4
Contribution.

 

(a)
If a claim for indemnification under Section 4.1 or 4.2 is unavailable to an Indemnified Party because of a failure or
refusal of a governmental authority to enforce such indemnification in accordance with its terms (by reason of public policy or
otherwise), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid
or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in
such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified
Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged
untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates
to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access
to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party
as a result of any Losses shall be deemed to include, subject to the limitations set forth in Section 4.3, any reasonable
attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such
party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available
to such party in accordance with its terms.

 

(b)
The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.4 were determined
by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred
to in the immediately preceding paragraph. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f)
of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

 

(c)
The indemnity and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties
may have to the Indemnified Parties. Notwithstanding anything to the contrary contained herein, the Holders shall be liable under
this Section 4.4 for only that amount as does not exceed the aggregate amount invested by such Holder under the Loan Agreement.

 

5
 Rule 144.

 

As
long as any Holder owns any Registrable Securities, Borrower Representative covenants to use its commercially reasonable efforts
to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be
filed by Borrower Representative after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange Act. As long as any
Holder owns any Registrable Securities, if Borrower Representative is not required to file reports pursuant to Section 13(a) or
15(d) of the Exchange Act, it will prepare and furnish to the Holders and make publicly available in accordance with Rule 144
annual and quarterly financial statements, together with a discussion and analysis of such financial statements in form and substance
substantially similar to those that would otherwise be required to be included in reports required by Section 13(a) or 15(d) of
the Exchange Act, as well as any other information required thereby, in the time period that such filings would have been required
to have been made under the Exchange Act. Borrower Representative further covenants that it will take such further action as any
Holder may reasonably request, all to the extent required from time to time to enable such Person to sell the Shares without registration
under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including
providing any legal opinions relating to such sale pursuant to Rule 144. Upon the request of any Holder, Borrower Representative
shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

 

    	 

    	 

    

 

6
Miscellaneous.

 

6.1
Remedies. In the event of a breach by Borrower Representative or by a Holder, of any of their obligations under this
Agreement, each Holder or Borrower Representative, as the case may be, in addition to being entitled to exercise all rights granted
by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this
Agreement. Borrower Representative and each Holder agree that monetary damages would not provide adequate compensation for any
losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the
event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would
be adequate.

 

6.2
Assignment of Registration Rights. The rights of each Holder hereunder, including the right to have Borrower Representative
register for resale Registrable Securities in accordance with the terms of this Agreement, shall be assignable by each Holder
of all or a portion of the Registrable Securities if: (i) the Holder agrees in writing with the transferee or assignee to assign
such rights, and a copy of such agreement is furnished to Borrower Representative within a reasonable time after such assignment,
(ii) Borrower Representative is, within a reasonable time after such transfer or assignment, furnished with written notice of
(a) the name and address of such transferee or assignee, and (b) the securities with respect to which such registration rights
are being transferred or assigned, (iii) following such transfer or assignment the further disposition of such securities by the
transferee or assignees is restricted under the Securities Act and applicable state securities laws, and (iv) at or before the
time Borrower Representative receives the written notice contemplated by clause (ii) of this Section, the transferee or assignee
agrees in writing with Borrower Representative to be bound by all of the provisions of this Agreement. The rights to assignment
shall apply to the Holders (and to subsequent) successors and assigns.

 

6.3
Notices and Communications to Holders. Unless otherwise indicated in a written notice by Administrative Agent to Borrower
Representative, Borrower Representative may deliver all notices, materials and other correspondence that is permitted or required
to be delivered to Holders to Administrative Agent in accordance with Section 10 of the Agreement, and Administrative Agent shall
promptly deliver the same to Holders.

 

    	 

    	 

    

 

PLAN
OF DISTRIBUTION

 

The
sellers of shares pursuant to this Registration Statement (the “Selling Stockholders”) and any of their pledgees,
donees, transferees, assignees or other successors-in-interest may, from time to time, sell, transfer or otherwise dispose of
any or all of their shares of Common Stock or interests in shares of Common Stock on any stock exchange, market or trading facility
on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices
at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at
negotiated prices. The Selling Stockholders may use one or more of the following methods when disposing of the shares or interests
therein:

 

	 	●	ordinary
    brokerage transactions and transactions in which the broker-dealer solicits purchasers;
	 	 	 
	 	●	block
    trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block
    as principal to facilitate the transaction;
	 	 	 
	 	●	purchases
    by a broker-dealer as principal and resale by the broker-dealer for its account;
	 	 	 
	 	●	an
    exchange distribution in accordance with the rules of the applicable exchange;
	 	 	 
	 	●	privately
    negotiated transactions;
	 	 	 
	 	●	through
    the writing or settlement of options, swaps, derivatives or other hedging transactions, whether through an options exchange
    or otherwise;
	 	 	 
	 	●	broker-dealers
    may agree with the Selling Stockholders to sell a specified number of such shares at a stipulated price per share;
	 	 	 
	 	●	in
    the over the counter market;
	 	 	 
	 	●	a
    combination of any such methods of disposition; and
	 	 	 
	 	●	any
    other method permitted pursuant to applicable law.

 

The
Selling Stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

 

Broker-dealers
engaged by the Selling Stockholders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser)
in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction
will not be in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction
a markup or markdown in compliance with FINRA IM-2440 or the successor to such FINRA rules.

 

The
Selling Stockholders may from time to time pledge or grant a security interest in some or all of the Shares owned by them and,
if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell shares of
Common Stock from time to time under the prospectus, or under an amendment to the prospectus under Rule 424(b) or other applicable
provision of the Securities Act of 1933, as amended (the “Securities Act”), amending the list of selling stockholders
to include the pledgee, transferee or other successors in interest as selling stockholders under the prospectus. The Selling Stockholders
do not expect these commissions and discounts to exceed what is customary in the types of transactions involved.

 

There
can be no assurance that any Selling Stockholder will sell any or all of the shares of Common Stock pursuant to the registration
statement, of which this prospectus forms a part.

 

 

    	 

    	 

    

 

The
Selling Stockholders may enter into option or other transactions with broker-dealers or other financial institutions or the creation
of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares
offered by the prospectus, which shares such broker-dealer or other financial institution may resell pursuant to the prospectus
(as supplemented or amended to reflect such transaction).

 

The
Selling Stockholders and any broker-dealer or agents that are involved in selling the shares of Common Stock may be deemed to
be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissionss
received by such broker-dealers or agents and any profit on the resale of Common Stock purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act. In no event shall any broker-dealer receive fees, commissions and markups which,
in the aggregate, would exceed eight percent (8%). Each Selling Stockholder has informed Borrower Representative that it does
not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the Common Stock.

 

We
have advised each Selling Stockholder that it may not use shares registered on the registration statement of which this prospectus
is a part to cover short sales of Common Stock made prior to the date on which the registration statement shall have been declared
effective by the Securities and Exchange Commission. If a Selling Stockholder uses this prospectus for any sale of shares of our
Common Stock, it will be subject to the prospectus delivery requirements of the Securities Act. The Selling Stockholders and any
other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934,
as amended, and the rules and regulations promulgated thereunder, including, without limitation, Regulation M of the Exchange
Act, which may limit the timing of purchases and sales of any of the shares of Common Stock by the Selling Stockholders and any
other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares
of Common Stock to engage in market-making activities with respect to the shares of Common Stock. All of the foregoing may affect
the marketability of the shares of Common Stock and the ability of any person or entity to engage in market-making activities
with respect to the shares of Common Stock.

 

We
may indemnify the Selling Stockholders against certain liabilities, including some liabilities under the Securities Act, in accordance

The
undersigned hereby acknowledges and is advised of the following Interpretation A.65 of the July 1997 SEC Manual of Publicly Available
Telephone Interpretations regarding short selling:

 

“An
Issuer filed a Form S-3 registration statement for a secondary offering of common stock which is not yet effective. One of the
selling shareholders wanted to do a short sale of common stock “against the box” and cover the short sale with registered
shares after the effective date. The issuer was advised that the short sale could not be made before the registration statement
become effective, because the shares underlying the short sale are deemed to be sold at the time such sale is made. There would,
therefore, be a violation of Section 5 if the shares were effectively sold prior to the effective date.”

 

By
returning this Questionnaire, the undersigned will be deemed to be aware of the foregoing interpretation.

 

I
confirm that, to the best of my knowledge and belief, the foregoing statements (including without limitation the answers to this
Questionnaire) are correct.

 

IN
WITNESS WHEREOF the undersigned, by authority duly given, has caused this Questionnaire to be executed and delivered either in
person or by its duly authorized agent.
