This

assignee or transferee of this Warrant or of any shares issued upon exercise hereof, “Holder”) is entitled
to purchase the number of fully paid and non-assessable shares (the “Shares”) of the above-stated class, series
and type of stock (the “Class”) of the above-named company (the “Company”) at the above-stated

Section
1. EXERCISE.

 

1.1 Method
of Exercise. Subject to Section 5.1(a), Holder may at any time and from time to time exercise this Warrant, in whole or in
part, by delivering to the Company the original of this Warrant together with a duly executed Notice of Exercise in substantially
the form attached hereto as Appendix 1 and, unless Holder is exercising this Warrant pursuant to a cashless exercise set
forth in Section 1.2, a check, wire transfer of same-day funds (to an account designated by the Company), or other form
of payment acceptable to the Company for the aggregate Warrant Price for the Shares being purchased.

 

    	 

     

    

 

1.2 Cashless
Exercise. On any exercise of this Warrant, in lieu of payment of the aggregate Warrant Price in the manner as specified in
Section 1.1 above, but otherwise in accordance with the requirements of Section 1.1, Holder may elect to receive
Shares equal to the value of this Warrant, or portion hereof as to which this Warrant is being exercised. Thereupon, the Company
shall issue to Holder such number of fully paid and non-assessable Shares as are computed using the following formula:

 

X
= Y(A-B)/A

 

where:

 

		X
                                         =	the
                                         number of Shares to be issued to Holder;

 

		Y
                                         =	the
                                         number of Shares with respect to which this Warrant is being exercised (inclusive of
                                         the Shares surrendered to the Company in payment of the aggregate Warrant Price);

 

		A
                                         =	the
                                         Fair Market Value (as determined pursuant to Section 1.3 below) of one Share;
                                         and

 

		B
                                         =	the
                                         Warrant Price.

 

1.3 Fair
Market Value. For purposes of this Warrant, the “Fair Market Value” shall mean the following: If the Company’s
common stock is then traded or quoted on a nationally recognized securities exchange, inter-dealer quotation system or over-the-counter
market (a “Trading Market”), the Fair Market Value of a Share shall be the closing price or last sale price
of a share of the Company’s common stock reported for the Business Day immediately before the date on which Holder delivers
this Warrant together with its Notice of Exercise to the Company. If the Company’s common stock is not traded in a Trading
Market, the Board of Directors of the Company shall determine the Fair Market Value of a Share in its reasonable good faith judgment.

 

1.4 Delivery
of Certificate and New Warrant. Within a reasonable time after Holder exercises this Warrant in the manner set forth in Section
1.1 or 1.2 above, the Company shall deliver to Holder a certificate representing the Shares issued to Holder upon such exercise
and, if this Warrant has not been fully exercised and has not expired, a new warrant of like tenor representing the Shares not
so acquired.

 

1.5 Replacement
of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in
form, substance and amount to the Company or, in the case of mutilation, on surrender of this Warrant to the Company for cancellation,
the Company shall, within a reasonable time, execute and deliver to Holder, in lieu of this Warrant, a new warrant of like tenor
and amount.

 

1.6 Treatment
of Warrant at Acquisition.

 

(a) In
the event of an Acquisition (as defined below) in which the consideration to be received by the Company’s stockholders consists
solely of cash, solely of Marketable Securities or a combination of cash and Marketable Securities (a “Cash/Public Acquisition”),
and the Fair Market Value of one Share as determined in accordance with Section 1.3 above as of the Business Day immediately
prior to the closing date for such Cash/Public Acquisition would be greater than the Warrant Price in effect on such date, and
Holder has not exercised this Warrant pursuant to Section 1.1 above as to all Shares, then this Warrant shall automatically
be deemed to be cashless exercised pursuant to Section 1.2 above as to all Shares effective immediately prior to and contingent
upon the consummation of such Cash/Public Acquisition. In connection with such cashless exercise, Holder shall be deemed to have
restated each of the representations and warranties in Section 4 of the Warrant as the date thereof and the Company shall
promptly notify the Holder of the number of Shares (or such other securities) issued upon exercise.

 

(b) Upon
the closing of any Acquisition other than as described in subsection (a) above, the acquiring, surviving or successor entity
shall assume the obligations of this Warrant, and this Warrant shall thereafter be exercisable solely for the same securities,
cash and/or other property as would have been paid for the Shares issuable upon exercise of the unexercised portion of this Warrant
as if such Shares were outstanding on and as of the closing of such Acquisition, subject to further adjustment from time to time
in accordance with the provisions of this Warrant.

 

    	2

     

    

 

(c) (i)
“Acquisition” means a transaction or series of related transactions involving (A) the sale, lease, exclusive
license or other disposition of all or substantially all assets of the Company, or (B) any merger or consolidation of the Company
into or with another person or entity, or any other corporate reorganization, as a result of which the stockholders of the Company
immediately prior to such transaction own less than a majority of the Company’s (or the surviving or successor entity’s)
outstanding voting power immediately after such transaction, or (C) any sale or other transfer that results in any “person”
or “group” (within the meaning of Section 13(d) and 14(d)(2) of the Exchange Act) becoming the “beneficial owner”
(as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of a sufficient number of Equity Interests of the Company
ordinarily entitled to vote in the election of directors, empowering such “person” or “group” to elect
a majority of the members of the Board of the Company, who did not have such power before such transaction, and (ii) “Marketable
Securities” means securities meeting all of the following requirements: (i) the issuer thereof is then subject to the
reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”), and is then current in its filing of all required reports and other information under the Act and the Exchange
Act; (ii) the class and series of shares or other security of the issuer that would be received by Holder in connection with the
Acquisition were Holder to exercise this Warrant on or prior to the closing thereof is then traded in a Trading Market, and (iii)
following the closing of such Acquisition, Holder would not be restricted from publicly re-selling all of the issuer’s shares
and/or other securities that would be received by Holder in such Acquisition were Holder to exercise or convert this Warrant in
full on or prior to the closing of such Acquisition, except to the extent that any such restriction (x) arises solely under federal
or state securities laws, rules or regulations, or (y) does not extend beyond six (6) months from the closing of such Acquisition.

 

1.7 Beneficial
Ownership. Notwithstanding anything herein to the contrary, the Company shall not be required to issue a number of Shares
upon exercise of this Warrant to the extent that, upon such issuance, the number of Shares of the Class then beneficially owned
by Holder and its Affiliates and any group of other persons or entities whose beneficial ownership of the Class would be aggregated
with Holder’s for purposes of Section 13(d) of the Exchange Act would exceed 9.985% of the total number of Shares of the
Class 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. For purposes of this Section 1.7, “group” has the meaning set forth in Section 13(d) of the
Exchange Act and applicable regulations of the Securities and Exchange Commission (the “Commission”), and the
percentage held by Holder shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act.
Upon the written request of Holder, the Company shall, within two (2) trading days, confirm to the Holder the number of shares
of the Class then outstanding. As used herein, beneficial ownership shall be determined in accordance with Section 13(d) of the
Exchange Act.

 

Section
2. ADJUSTMENTS TO THE SHARES AND WARRANT PRICE.

 

2.1 Stock
Dividends, Splits, Etc. If the Company declares or pays a dividend or distribution on the outstanding shares of the Class
payable in common stock or other securities or property (other than cash), then upon exercise of this Warrant, for each Share
acquired, Holder shall receive, without additional cost to Holder, the total number and kind of securities and property which
Holder would have received had Holder owned the Shares of record as of the date the dividend or distribution occurred. If the
Company subdivides the outstanding shares of the Class by reclassification or otherwise into a greater number of shares, the number
of Shares purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased. If
the outstanding shares of the Class are combined or consolidated, by reclassification or otherwise, into a lesser number of shares,
the Warrant Price shall be proportionately increased and the number of Shares shall be proportionately decreased.

 

2.2 Reclassification,
Exchange, Combinations or Substitution. Upon any event whereby all of the outstanding shares of the Class are reclassified,
converted, exchanged, combined, substituted, or replaced for, into, with or by Company securities of a different class and/or
series, then from and after the consummation of such event, this Warrant will be exercisable for the number, class and series
of Company securities that Holder would have received had the Shares been outstanding on and as of the consummation of such event,
and subject to further adjustment thereafter from time to time in accordance with the provisions of this Warrant. The provisions
of this Section 2.2 shall similarly apply to successive reclassifications, exchanges, combinations, substitutions, replacements
or other similar events.

 

2.3 No
Fractional Share. No fractional Share shall be issuable upon exercise of this Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share. If a fractional Share interest arises upon any exercise of the Warrant, the
Company shall eliminate such fractional Share interest by paying Holder in cash the amount computed by multiplying the fractional
interest by (i) the Fair Market Value (as determined in accordance with Section 1.3 above) of a full Share, less (ii) the
then-effective Warrant Price.

 

    	3

     

    

 

2.4 Notice/Certificate
as to Adjustments. Upon each adjustment of the Warrant Price, Class and/or number of Shares, the Company, at the Company’s
expense, shall notify Holder in writing within a reasonable time setting forth the adjustments to the Warrant Price, class and/or
number of Shares and facts upon which such adjustment is based. The Company shall, upon written request from Holder, furnish Holder
with a certificate of its Chief Financial Officer, including computations of such adjustment and the Warrant Price, class and
number of Shares in effect upon the date of such adjustment.

 

Section
3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

and non-assessable, and free of any liens and encumbrances except for restrictions on transfer provided for herein or under applicable
federal and state securities laws. The Company covenants that it shall at all times cause to be reserved and kept available out
of its authorized and unissued capital stock such number of shares of the Class, as will be sufficient to permit the exercise

(b) The
issuance of this Warrant and the issuance of the Shares issuable upon exercise hereof, does not entitle any other party to exercise
preemptive rights, except to the extent waived prior to the Issue Date.

(a) declare
any dividend or distribution upon the outstanding shares of the Class, whether in cash, property, stock, or other securities and

(b) offer
for subscription or sale pro rata to the holders of the outstanding shares of the Class any additional shares of any class or
series of the Company’s stock (other than pursuant to contractual pre-emptive rights);

 

(c) effect
any reclassification, exchange, combination, substitution, reorganization or recapitalization of the outstanding shares of the
Class; or

 

(d)

      then,
in connection with each such event, the Company shall give Holder:

 

(1) in
the case of the matters referred to in (a) and (b) above, at least five (5) Business Days prior written notice of the earlier

rights to vote, if any; and

 

(2) in
the case of the matters referred to in (c) and (d) above at least twenty (20) days prior written notice of the date when the same

be entered into in connection with such transaction to effect the exchange and the treatment of this Warrant in connection with
such event giving rise to the notice).

 

    	4

     

    

 

If
at any time Company is not required to file financial statements and reporting with the Securities and Exchange Commission (the
‘Commission”), Company will also provide information requested by Holder that is reasonably necessary to enable
Holder to comply with Holder’s accounting or reporting requirements, including without limitation, quarterly financial statements
no later than 45 days of the end of each fiscal quarter of the Company and annual financial statements no later than 90 days of
the end of each fiscal year of Company, in each case, in the form as and when delivered to Company’s stockholders.

the meaning of the Act. Holder also represents that it has not been formed for the specific purpose of acquiring this Warrant
or the Shares.

 

4.2 Disclosure
of Information. Holder is aware of the Company’s business affairs and financial condition and has received or has had
full access to all the information it considers necessary or appropriate to make an informed investment decision with respect
to the acquisition of this Warrant and its underlying securities. Holder further has had an opportunity to ask questions and receive

effort or expense) necessary to verify any information furnished to Holder or to which Holder has access.

in financial or business matters that Holder is capable of evaluating the merits and risks of its investment in this Warrant and

4.5 The
Act. Holder understands that this Warrant and the Shares issuable upon exercise hereof have not been registered under the

Holder’s investment intent as expressed herein. Holder understands that this Warrant and the Shares issued upon any exercise
hereof must be held indefinitely unless subsequently registered under the Act and qualified under applicable state securities
laws, or unless exemption from such registration and qualification are otherwise available. Holder is aware of the provisions
of Rule 144 promulgated under the Act.

 

4.6 No
Voting Rights. Holder, as a Holder of this Warrant, will not have any voting rights with respect to the Shares until the issuance

(b) Automatic
Cashless Exercise upon Expiration. In the event that, upon the Expiration Date, the Fair Market Value of one Share (or other
security issuable upon the exercise hereof) as determined in accordance with Section 1.3 above is greater than the Warrant
Price in effect on such date, then this Warrant shall automatically be deemed on and as of such date to be exercised pursuant
to Section 1.2 above as to all Shares (or such other securities) for which it shall not previously have been exercised,
and the Company shall, within a reasonable time, deliver a certificate representing the Shares (or such other securities) issued
upon such exercise to Holder.

The Shares shall be imprinted with a legend in substantially the following form:

or assigned in whole or in part except in compliance with applicable federal and state securities laws by the transferor and the
transferee (including, without limitation, the delivery of investment representation letters and legal opinions reasonably satisfactory
to the Company, as reasonably requested by the Company). The Company shall not require Holder to provide an opinion of counsel
if the transfer is to any affiliate of Holder, provided that any such transferee is an “accredited investor” as defined

registration
rights addendum

 

(a)
For purposes of this Addendum, the following terms shall have the meanings set forth below:

 

“Prospectus”
means the prospectus or prospectuses included in any Registration Statement, as amended or supplemented by any prospectus supplement
with respect to the terms of the offering of any portion of the Registrable Securities covered by such Registration Statement
and by all other amendments and supplements to the prospectus, including post- effective amendments and all material incorporated
by reference in such prospectus or prospectuses.

 

“Registrable
Securities” means (x) any shares of Common Stock held by any Person or issuable upon conversion, exercise or exchange
of any securities owned by any Person at any time (including the Shares exercisable upon exercise of this Warrant), and (y) any
shares of Common Stock issued or issuable with respect to any shares described in subsection (x) above by way of a stock dividend
or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization
(it being understood that for purposes of this Warrant, a Person shall be deemed to be a holder of Registrable Securities whenever
such Person has the right to then acquire or obtain from the Company any Registrable Securities, whether or not such acquisition
has actually been effected). As to any particular Registrable Securities, such securities shall cease to be Registrable Securities
when (i) a Registration Statement covering such securities has been declared effective by the Commission and such securities have
been disposed of pursuant to such effective Registration Statement, (ii) such securities are sold under circumstances in which
all of the applicable conditions of Rule 144 (or any similar provisions then in force) under the Securities Act are met, (iii)
such securities are otherwise transferred and such securities may be resold without subsequent registration under the Securities
Act, or (iv) such securities shall have ceased to be outstanding.

 

“Registration
Statement” means any registration statement of the Company which covers any of the Registrable Securities pursuant to
the provisions of this Agreement, including the Prospectus, amendments and supplements to such Registration Statement, including
post- effective amendments, all exhibits and all materials incorporated by reference in such Registration Statement.

 

(b) Whenever
the Company proposes to register any shares of its Common Stock under the Act (other than (i) a registration effected solely to
implement an employee benefit plan or a transaction to which Rule 145 of the Act is applicable, or (ii) a Registration Statement
on Form S-4, S-8 or any successor form thereto or another form not available for registering the Registrable Securities for sale
to the public) whether for its own account or for the account of one or more stockholders of the Company and the form of Registration
Statement to be used may be used for any registration of Shares (a “Piggyback Registration”), the Company shall
give prompt written notice (in any event no later than twenty (20) days prior to the filing of such Registration Statement) to
the Holder of its intention to effect such a registration and shall include in such registration all Shares with respect to which
the Company has received written requests for inclusion from the Holder within ten days after the Company’s notice has been
given to the Holder.

 

(c) If
the managing underwriter advises the Company and the Holder (if the Holder has elected to include Shares in such Piggyback Registration)
in writing that in its opinion the number of shares of Common Stock proposed to be included in such registration, including all
Registrable Securities and all other shares of Common Stock proposed to be included in such underwritten offering, exceeds the
number of shares of Common Stock which can be sold in such offering and/or that the number of shares of Common Stock proposed
to be included in any such registration would adversely affect the price per share of the Common Stock to be sold in such offering,
the Company shall include in such registration (A) first, the number of shares of Common Stock that the Company proposes to sell
(if any); (B) second, the number of shares of Common Stock requested to be included therein by the Holder; and (C) third, the
number of shares of Common Stock requested to be included therein by holders of Common Stock (other than Shares held by the Holder).

 

    	 

     

    

 

(d) If
and whenever the Holder requests that any Shares be included in a Registration Statement in accordance with subsection (a)
or (b), the Company shall use its best efforts to include the Shares in such registration in accordance with the intended
method of disposition thereof, and pursuant thereto the Company shall as soon as practicable:

 

(i) at
least five (5) Business Days before filing such Registration Statement, Prospectus or amendments or supplements thereto, furnish
to counsel of the Holder copies of such documents proposed to be filed;

 

(ii) notify
the Holder, promptly after the Company receives notice thereof, of the time when such Registration Statement has been declared
effective or a supplement to any Prospectus forming a part of such Registration Statement has been filed;

 

(iii) furnish
to the Holder such number of copies of the Prospectus included in such Registration Statement (including each preliminary Prospectus)
and any supplement thereto (in each case including all exhibits and documents incorporated by reference therein) and such other
documents as the Holder may request in order to facilitate the disposition of the Shares;

 

(iv) notify
the Holder, at any time when a Prospectus relating thereto is required to be delivered under the Act, of the happening of any
event as a result of which the Prospectus included in such Registration Statement contains an untrue statement of a material fact
or omits any fact necessary to make the statements therein not misleading, and, at the request of any such holder, the Company
shall prepare a supplement or amendment to such Prospectus so that, as thereafter delivered to the purchasers of such Shares,
such Prospectus shall not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements
therein not misleading;

 

(v) use
its commercially reasonable efforts to cause such Shares to be listed on each securities exchange on which the Common Stock is
then listed;

 

(vi) in
connection with an underwritten offering, enter into such customary agreements (including underwriting and lock-up agreements
in customary form) and take all such other customary actions as the Holder or the managing underwriter of such offering request
in order to expedite or facilitate the disposition of such Shares (including, without limitation, making appropriate officers
of the Company available to participate in “road show” and other customary marketing activities, including one-on-one
meetings with prospective purchasers of the Shares);

 

(vii) otherwise
use its reasonable best efforts to comply with all applicable rules and regulations of the Commission and make available to its
stockholders an earnings statement (in a form that satisfies the provisions of Section 11(a) of the Act and Rule 158 thereunder)
no later than thirty (30) days after the end of the 12-month period beginning with the first day of the Company’s first
full fiscal quarter after the effective date of such Registration Statement, which earnings statement shall cover said 12-month
period, and which requirement will be deemed to be satisfied if the Company timely files complete and accurate information on
Forms 10-Q, 10-K and 8-K under the Exchange Act and otherwise complies with Rule 158 under the Act;

 

(viii) furnish
to the Holder and each underwriter, if any, with (i) a legal opinion of the Company’s outside counsel, dated the effective
date of such Registration Statement (and, if such registration includes an underwritten public offering, dated the date of the
closing under the underwriting agreement), in form and substance as is customarily given in opinions of the Company’s counsel
to underwriters in underwritten public offerings; and (ii) a “comfort” letter signed by the Company’s independent
certified public accountants in form and substance as is customarily given in accountants’ letters to underwriters in underwritten
public offerings;

 

(ix) without
limiting Section 5.2(f) above, use its best efforts to cause such Shares to be registered with or approved by such other
governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the
Holder to consummate the disposition of such Shares in accordance with their intended method of distribution thereof;

 

(x) notify
the Holder promptly of any request by the Commission for the amending or supplementing of such Registration Statement or Prospectus
or for additional information; and

 

(xi) advise
the Holder, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission
suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose
and promptly use its best efforts to prevent the issuance of any stop order or to obtain its withdrawal at the earliest possible
moment if such stop order should be issued.

2.
LOAN AND TERMS OF PAYMENT

 

2.1
Promise to Pay. Each Borrower hereby unconditionally promises to pay Administrative Agent, for the ratable benefit of Lenders,
the outstanding principal amount of all Loans, accrued and unpaid interest, fees and charges thereon and to pay all Obligations
as and when due in accordance with this Agreement.

 

2.2
Availability and Repayment or Conversion of the Loans.

 

(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 a principal amount equal to its First Tranche Term Loan Commitment (the “First Tranche
Term Loans”). Lenders’ commitments to make the First Tranche Term Loans shall terminate upon the funding of the
First Tranche Term Loans on the Closing Date.

 

(ii)
Subject to achievement of the Lenabasum Phase 3 Milestone and the terms and conditions of this Agreement, each Lender agrees,
severally and not jointly, to make to Borrowers an additional advance during the Second Tranche Availability Period in a principal
amount equal to its Second Tranche Term Loan Commitment (the “Second Tranche Term Loans”). Lenders’ commitments
to make the Second Tranche Term Loans shall terminate upon the earlier of (i) the end of the Second Tranche Availability Period,
and (ii) the date the Second Tranche Term Loans have been funded.

 

    	 	 	 

     

    

 

(iii)
Subject to achievement of the Lenabasum Approval Milestone and the terms and conditions of this Agreement, each Lender agrees,
severally and not jointly, to make to Borrowers an additional advance during the Third Tranche Availability Period in a principal
amount equal to its Third Tranche Term Loan Commitment (the “Third Tranche Term Loans”, and together with the
First Tranche Term Loan, and the Second Tranche Term Loan, collectively, the “Term Loans”, and each, a “Term
Loan”). Lenders’ commitment to make the Third Tranche Term Loans shall terminate upon the earlier of (i) the end
of the Third Tranche Availability Period, and (ii) the date that Third Tranche Term Loans have been funded.

 

Borrowers
shall use the proceeds of the Term Loans for working capital. Once repaid, the Term Loans may not be reborrowed. For the avoidance
of doubt, other than the incurrence of the First Tranche Term Loans on the Closing Date, Borrowers are not under any obligation
to request or borrow any other Term Loans from Lenders.

 

(b)
Repayment. Commencing on the Amortization Date, and continuing thereafter on 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 accordance with its terms, the amortization schedule and the required monthly
installment shall be recalculated based on the adjusted Applicable Rate and/or the adjusted number of Payment Dates from the adjusted
Amortization Date through the Term Loan Maturity Date. 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 or Change of Control. If the Loans are accelerated in accordance with the terms
hereof following the occurrence and during the continuance of an Event of Default or a Change of Control occurs, Borrowers shall
immediately pay to Administrative Agent, for the ratable benefit of Lenders, an amount equal to the sum of:

 

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

 

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

 

(iii)
all other sums, if any, that shall have become due and payable, including, if applicable, 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 Administrative Agent, for the ratable benefit of the 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.

 

    	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 in a minimum amount of $500,000
(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 Borrower
Representative, provided that (1) the aggregate principal amount converted to Common Stock in accordance with this Section
2.2(e) shall not exceed $5,000,000 and (2) each converting Lender has completed and delivered to Parent an accredited investor
questionnaire in the form attached hereto as Annex B to Schedule 4. A Conversion Election Notice, once delivered,
shall be irrevocable unless otherwise agreed in writing by Borrower Representative. 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, subject to Suspension Periods (as defined on Schedule 4), 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) to sell
shares of Common Stock issued pursuant to a Conversion Election Notice to the public without registration, Borrower Representative
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; and (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 Borrower Representative
under Section 13 or 15(d) of the 1934 Act.

 

(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 would
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, Parent and Borrower Representative and any of their Subsidiaries may
enter into any Change of Control transaction that results in the delisting of the Common Stock from any such national securities
exchange, subject to mandatory prepayment in accordance with Section 2.2(c).

 

(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.

 

(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 and shares of Common Stock pursuant to exercise
of the Warrant, would result in the issuance of more than 19.99% of the Common Stock outstanding as of the date of this Agreement.

 

    	3

     

    

 

(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 of
Common Stock 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 September 1, 2020.

 

(b)
Default Rate. Upon the occurrence and during the continuance of an Event of Default, at the option of Administrative Agent
following notice thereof to Borrower Representative, (i) Obligations shall bear interest at a rate per annum which is five percentage
points (5.0%) above the rate that is otherwise applicable thereto (the “Default Rate”) and (ii) 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 to the Obligations. 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 3:00 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.

 

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)
Lender Expenses. All Lender Expenses (including reasonable and documented out-of-pocket 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 three (3) Business Days after demand by Administrative Agent); and subject to offset
of the deposit paid prior to the Closing Date and certain limitations, in each case, as set forth in the Fee Letter.

 

    	4

     

    

 

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

 

(a)
All payments to be made by Borrowers 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 3:00 p.m. Eastern Time on the date when due. Payments of principal and/or interest received after 3:00
p.m. Eastern Time shall be 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 Borrower 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 Borrower 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; provided, however, that so
long as no Event of Default has occurred and is continuing, Administrative Agent shall provide Borrower Representative with prior
written notice before debiting Borrowers’ deposit accounts for amounts other than principal, interest and payments of regularly
scheduled fees. These debits shall not constitute a set-off. If the ACH payment arrangement is terminated for any reason, Borrowers
shall make all payments due hereunder at the applicable address specified in Section 10, or as otherwise notified by Administrative
Agent in writing.

 

(d)
Borrowers, Administrative Agent, Collateral Trustee and each Lender hereby agree to the terms and conditions set forth on Schedule
3 hereto.

 

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, or to be made by, 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 G,
and (b) upon any Lender’s written request, and in any event within three (3) Business Days of any such request, 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 Borrowers promptly following such 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.

CREATION OF SECURITY INTEREST

 

4.1
Grant of Security Interest. Each Loan Party hereby grants to Collateral Trustee, for the ratable benefit of Lenders, to secure
the payment and performance in full of all of the Obligations, a continuing security interest in, and pledges to Collateral Trustee,
the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. If
this Agreement is terminated, Collateral Trustee’s Lien in the Collateral shall continue until the Obligations (other than
contingent indemnification obligations as to which no claim has been asserted or is known to exist) are repaid in full in cash.

 

4.2
Priority of Security Interest. Each Loan Party represents, warrants, and covenants that the security interest granted herein
is and shall at all times continue to be a first priority perfected security interest in the Collateral (subject only to Permitted
Liens). If a Loan Party shall acquire a commercial tort claim with a potential recovery in excess of $500,000, such Loan Party
shall promptly notify Administrative Agent in writing and deliver such other information and documents as Administrative Agent
may reasonably require to take any further action necessary or advisable to perfect Collateral Trustee’s Lien in such commercial
tort claim. If a Loan Party shall acquire any instrument with a value in excess of $500,000, such Loan Party shall promptly notify
Administrative Agent and deliver the same in original to the Collateral Trustee together with an allonge or other appropriate
instrument of transfer and any necessary endorsement, all in form reasonably satisfactory to Administrative Agent.

 

4.3
Authorization to File Financing Statements. Each Loan Party hereby authorizes Collateral Trustee or its designee (or the Administrative
Agent, on behalf of the Collateral Trustee) to file at any time financing statements, continuation statements and amendments thereto
with all appropriate jurisdictions to perfect or protect Collateral Trustee’s interest or rights hereunder.

 

4.4
Pledge of Collateral. Each Loan Party hereby pledges, assigns as collateral and grants to Collateral Trustee a security interest
in the Shares, together with all proceeds and substitutions thereof, all cash, stock and other moneys and property paid thereon,
all rights to subscribe for securities declared or granted in connection therewith, and all other cash and noncash proceeds of
the foregoing, as security for the performance of the Obligations. On the Closing Date or to the extent any Shares pledged hereunder
from time to time are or become certificated and either (i) represent Equity Interests of a Subsidiary or (ii) have a value in
excess of $500,000, such certificate or certificates shall be delivered to Collateral Trustee, accompanied by a stock power or
other appropriate instrument of assignment duly executed in blank. To the extent required by the terms and conditions governing
the Equity Interests in which a Loan Party has an interest, such Loan Party shall cause the books of each Person whose Equity
Interests are part of the Collateral and any transfer agent to reflect the pledge of the Equity Interests. Upon the occurrence
and during the continuation of an Event of Default hereunder, Collateral Trustee may effect the transfer of any securities included
in the Collateral (including but not limited to the Equity Interests) into the name of Collateral Trustee and cause new certificates
representing such securities to be issued in the name of Collateral Trustee or its transferee. Each Loan Party will execute and
deliver such documents, and take or cause to be taken such actions, as Administrative Agent may reasonably request to perfect
or continue the perfection of Collateral Trustee’s security interest in the Equity Interests. Each Loan Party shall be entitled
to exercise any voting rights with respect to the Equity Interests in which it has an interest and to give consents, waivers and
ratifications in respect thereof, unless following an Event of Default, Collateral Trustee shall have given notice to Borrower
Representative suspending such rights, provided that: no such notice shall be required if a Loan Party has commenced an Insolvency
Proceeding and, in any event, no vote shall be cast or consent, waiver or ratification given or action taken which would be inconsistent
with any of the terms of this Agreement or which would constitute or create any violation of any of such terms. All such rights
to vote and give consents, waivers and ratifications shall terminate upon the occurrence and during the continuation of an Event
of Default.

jurisdictions of formation and are qualified and licensed to do business and are in good standing in any other jurisdiction in
which the conduct of their respective business or ownership of property require that they be qualified except where the failure
to do so would not reasonably be expected to have a Material Adverse Effect. In connection with this Agreement, Borrower Representative
has delivered to Administrative Agent a completed certificate signed by Borrower Representative entitled “Perfection

with Section 7.2, (i) each Loan Party’s exact legal name is that indicated on the Perfection Certificate and

mailing address (if different than its chief executive office); (v) except as set forth in the Perfection Certificate, each
Loan Party (and each of its predecessors) has not, in the past five (5) years, changed its jurisdiction of formation, organizational
structure or type, or any organizational number assigned by its jurisdiction; and (vi) as of the date hereof, all other information
set forth on the Perfection Certificate pertaining to each Loan Party and each of its Subsidiaries is accurate and complete in
all material respects (it being understood and agreed that each Loan Party may from time to time update certain information in
the Perfection Certificate after the Closing Date to the extent the change does not arise from an action, event or circumstance
restricted by one or more specific provisions in this Agreement).

 

(b)
The execution, delivery and performance by each Loan Party of the Loan Documents to which it is a party have been duly authorized,
and do not (i) conflict with such Loan Party’s Operating Documents or other organizational documents, (ii) contravene,
conflict with, constitute a default under or violate any material Requirement of Law, (iii) contravene, conflict or violate

Governmental Approvals which have already been obtained and are in full force and effect), or (v) conflict with, contravene,

such Loan Party is bound. No Loan Party is in default under any agreement to which it is a party or by which it is bound in which
the default would reasonably be expected to have a Material Adverse Effect.

 

5.2
Collateral.

 

(a)
Each Loan Party has good title to or a valid leasehold interest in, rights in, and the power to transfer each item of the Collateral
upon which it purports to grant a Lien hereunder, free and clear of any and all Liens except Permitted Liens.

Except for the Collateral Accounts described in the Perfection Certificate or in a notice timely delivered pursuant to Section
6.6, no Loan Party has any Collateral Accounts at or with any bank, broker or other financial institution, and each Loan Party
has taken such actions as are necessary to give Collateral Trustee a perfected security interest therein as required pursuant
to the terms of Section 6.6(b). To the knowledge of Borrower, the Accounts, if any, are bona fide, existing obligations
of the Account Debtors.

The Collateral is located only at the locations identified in the Perfection Certificate and other Permitted Locations. The Collateral

Parties, valid and enforceable, and no part of the Intellectual Property which a Loan Party owns or purports to own and which
is material to the Loan Parties’ business has, to the knowledge of the Loan Parties, been judged invalid or unenforceable,
in whole or in part. To the knowledge of the Loan Parties, no claim has been made that any part of the Intellectual Property violates
the rights of any third party except to the extent such claim would not reasonably be expected to have a Material Adverse Effect.
Except as noted on the Perfection Certificate or as disclosed pursuant to Section 6.7(b), no Loan Party is a party to,
nor is it bound by, any Restricted License. No Subsidiary which is not a Loan Party owns any Intellectual Property, which, if
not owned by Loan Parties and their Subsidiaries would reasonably be expected to have a Material Adverse Effect.

 

5.3
Accounts; Material Agreements. To the knowledge of Borrower, the Accounts, if any, are bona fide existing obligations. The
property or services giving rise to such Accounts have been delivered or rendered. The licenses and agreements to which any Loan
Party or any of its Subsidiaries is a party are in full force and effect and no Loan Party is in material breach with respect
thereto, except to the extent of any such licenses and agreements, the failure of which to maintain would not reasonably be expected
to result in a Material Adverse Effect.

 

5.4
Litigation and Proceedings. Except as set forth in the Perfection Certificate or as disclosed in writing pursuant to Section
6.2, there are no actions, suits, litigations or proceedings, at law or in equity, pending, or, to the knowledge of any Responsible
Officer, threatened in writing, by or against any Loan Party or any of its Subsidiaries, officers or directors involving more
than, individually or in the aggregate for all related proceedings, $500,000 or in which any adverse decision has had or would
reasonably be expected to have a Material Adverse Effect.

 

5.5
Financial Statements; Financial Condition. All consolidated and consolidating (if any) 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 (if any) 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 in accordance with GAAP, and there are no material liabilities
(including any contingent liabilities) which are not reflected in such financial statements. There has not been any material deterioration
in the consolidated and consolidating financial condition of the Loan Parties and each of its Subsidiaries or the Collateral since
the date of the most recent financial statements submitted to Administrative Agent.

 

5.6
Solvency. The fair salable value of the assets (including goodwill minus disposition costs) of the Loan Parties and each of
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 the Loan Parties and their Subsidiaries, on a consolidated basis, are able to pay their debts (including trade debts) as they
mature.

 

5.7
Consents; Approvals. Each Loan Party and each of its Subsidiaries have obtained all third party consents, approvals, waivers,
made all declarations or filings with, given all notices to, and obtained all consents, licenses, permits or other approvals from
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 would 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
to Administrative Agent pursuant to Section 6.11 below. No Loan Party owns any stock, partnership, or other ownership interest

federal income tax returns and material foreign, state and local tax returns and reports (or appropriate extensions therefor),
and such Loan Party and each of its Subsidiaries has timely paid or caused to be paid all foreign, federal, state and local taxes,
assessments, deposits and contributions owed by such Loan Party or such Subsidiary, as applicable, except (a) to the extent
such taxes are being contested in good faith by appropriate proceedings promptly instituted and diligently conducted, so long
as such reserve or other appropriate provision, if any, as shall be required in conformity with GAAP shall have been made therefor,
or (b) if such taxes, assessments, deposits and contributions do not, individually or in the aggregate, exceed $25,000. No
Loan Party is aware of any claims or adjustments proposed for any prior tax years of such Loan Party or any of its Subsidiaries
which would reasonably be expected to result in a material amount of additional taxes becoming due and payable by such Loan Party
or Subsidiary.

 

5.10

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

in the Investment Company Act of 1940 as amended.

 

(b)
No Loan Party or Subsidiary of a Loan Party is engaged, nor will it engage, principally or as one of its important activities,
in the business of extending credit for the purpose of “purchasing” or “carrying” any “margin security”
as such terms are defined in Regulation U of the Federal Reserve Board as now and from time to time hereafter in effect (such
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.

 

(c)
No Loan Party has taken or permitted to be taken any action which might cause any Loan Document to which it is a party to violate
any regulation of the Federal Reserve Board. Neither the making of the Loans hereunder nor Borrowers’ use of the proceeds
thereof will violate the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United
States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating
thereto. No Loan Party, nor any of its Subsidiaries, nor any Affiliate of any Loan Party or of any Subsidiary, nor any controlling
holder of Equity Interests of any of the foregoing (i) is a Person described or designated in the Specially Designated Nationals
and Blocked Persons List of the Office of Foreign Assets Control of the United States Department of Treasury (“OFAC”)
or in Section 1 of the Anti-Terrorism Order or similar sanctions laws of any other Governmental Authority including of any other
applicable jurisdiction, (ii) is a citizen or resident of any country that is subject to embargo or trade sanctions enforced by
OFAC, (iii) is, or will become, a Person whose property or interest in property is blocked or subject to blocking pursuant to
Section 1 of the Anti-Terrorism Order, or (iv) engages in any dealings or transactions, or is otherwise associated, with any such
Person.

 

(d)
Each Loan Party and its Subsidiaries are in compliance, in all material respects, with the USA Patriot Act. 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 States Foreign
Corrupt Practices Act of 1977, as amended.

 

(e)
No Reportable Event 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 a hazardous materials disposal site, or has received any notice, summons, citation or directive from the
Environmental Protection Agency or any other similar Governmental Authority.

Governmental Approvals required for the testing, manufacturing, marketing or sale of the Products, a list of which is set forth

are no proceedings in progress, pending or, to such Loan Party’s knowledge,
threatened, that may result in revocation, cancellation, suspension, rescission or any adverse modification of any such material
Governmental Approval which would reasonably be expected to result in a Material Adverse Effect, nor, to the best of the knowledge,
information and belief of such Loan Party, after due inquiry, are there any facts
upon which proceedings would reasonably be based. Without limitation of the foregoing:

 

(a)
With respect to any Product being tested or manufactured, each Loan Party and each of its Subsidiary has received, and such Product
is the subject of, all material Governmental Approvals needed in connection with the testing or manufacture of such Product as
such testing is currently being conducted by or on behalf of a Loan Party or any of its Subsidiaries, and neither any Loan Party
nor any of its Subsidiaries has received any notice from any applicable Governmental Authority, that such Governmental Authority
is conducting an investigation or review of (i) any Loan Party’s or any of its Subsidiary’s manufacturing facilities
and processes for such Product which have disclosed any material deficiencies or violations of any Requirement of Law or the Governmental
Approvals related to the manufacture of such Product, or (ii) any such Governmental Approval or that any such Governmental Approval
has been revoked or withdrawn, nor has any such Governmental Authority issued any order or recommendation stating that the development,
testing and/or manufacturing of such Product should cease, in each case, which would reasonably be expected to result in a Material
Adverse Effect.

 

(b)
With respect to any Product marketed or sold by a Loan Party or any of its Subsidiaries,
such Loan Party or such Subsidiary, as applicable, has received, and such Product
is the subject of, all material Governmental Approvals needed in connection with the marketing and sales of such Product as currently

or review of any such Governmental Approval or approval or that any such Governmental Approval has been revoked or withdrawn,

cease or that such Product be withdrawn from the marketplace, in each case, which would reasonably be expected to have a Material
Adverse Effect;

a Material Adverse Effect; and

 

(d)
There have been no Product recalls or voluntary Product withdrawals from any market, in each case, which would reasonably be expected
to have a Material Adverse Effect.

 

5.13
Royalty and Milestone Payments. As of the date of this Agreement, except as set forth on Schedule 5, no Loan Party
is obligated to make Royalty and Milestone Payments in excess of $250,000 in the aggregate per fiscal year.

 

5.14
Full Disclosure. No written representation, warranty or other statement of a Loan Party or any of its Subsidiaries in any
certificate or written statement delivered by or on behalf of a Loan Party or any of its Subsidiaries to Administrative Agent
or any Lender in connection with this Agreement, as of the date such representation, warranty, or other statement was made, taken
together with all such written certificates and written statements given, contains any untrue statement of a material fact or
omits to state a material fact necessary to make the statements contained in the certificates or written statements not materially
misleading in light of the circumstances under which they were made (it being recognized that the projections and forecasts provided
by any Loan Party in good faith and based upon reasonable assumptions are not viewed as facts and that actual results during the
period or periods covered by such projections and forecasts may differ from the projected or forecasted results).

to which it is subject except where a failure to do so would not reasonably be expected to have a Material Adverse Effect; obtain
all of the material Governmental Approvals required in connection with such Loan Party’s business (in each case, the failure

as the replaced or repaired Collateral and (ii) shall be Collateral in which Collateral Trustee has been granted a first
priority security interest and (b) after the occurrence and during the continuation of an Event of Default, all such net cash

Trustee thirty (30) days prior written notice before any such policy or policies shall be canceled (or ten (10) days’
notice for cancellation for non-payment of premiums).

 

(e)
If any Loan Party fails to obtain insurance as required under this Section 6.5 or to pay any amount or furnish any
required proof of payment upon Administrative Agent’s request, Collateral Trustee may make all or part of such payment or

material to its business; not suffer any material claim of infringement by another Person that would reasonably be expected to
have a Material Adverse Effect unless such claim is dismissed within thirty (30) days from initiation thereof or Borrower Representative
has demonstrated to Administrative Agent’s satisfaction that such proceedings are without merit and adequate reserves have
been taken; and, except for Permitted Transfers, not allow any Intellectual Property material to the Loan Parties’ business

extent that Administrative Agent, Collateral Trustee or such Lender may deem them reasonably necessary to prosecute or defend
any third-party suit or proceeding instituted by or against Administrative Agent, Collateral Trustee or such Lender with respect
to any Collateral or relating to such Loan Party.

 

6.9

prior to each third party inspection and audit, Administrative Agent shall, at the request of Borrower Representative, notify
Borrower Representative of the estimated costs to be incurred in connection therewith.

 

6.10
Financial Covenants.

 

(a)
Minimum Liquidity:

 

(i)
If the Liquidity Covenant Trigger has occurred, then thereafter, Loan Parties shall maintain at all times Unrestricted Cash in
an amount of at least $10,000,000; provided, however, that notwithstanding the foregoing, the foregoing covenant shall

    	15

     

    

 

(ii)
If the Second Tranche Term Loan is made hereunder, the covenant in this subsection (ii) shall apply: If the Lenabasum Approval
Milestone is not met on or prior to March 31, 2022, or if prior to such date any event occurs, or circumstance or condition exists,
as a result of which it is inevitable that the Lenabasum Approval Milestone will not be achieved on or prior to March 31, 2022,
then at all times thereafter, Loan Parties shall maintain Unrestricted Cash in an amount of at least the aggregate principal amount
of all Term Loans outstanding as of any date of determination; provided, however, that notwithstanding the foregoing, the
foregoing covenant shall not apply during any period in which Parent’s Market Capitalization remains above $500,000,000
or during any period for which compliance with the foregoing is waived by Administrative Agent in its sole and absolute discretion.

 

(iii)
Notwithstanding anything to the contrary in this Agreement, with respect to any failure to maintain Unrestricted Cash as required
in accordance with subsections (i) or (ii) above, but only to the extent the shortfall in Unrestricted Cash is not greater
than $3,000,000 (an “Eligible Liquidity Covenant Default”):

 

(1)
Borrower Representative may deliver a written notice no later than three (3) days following the date the Eligible Liquidity Covenant
Default occurred indicating that Borrowers have elected to cure such Eligible Liquidity Covenant Default in accordance with this
Section 6.10(a);

 

(2)
No later than the date that is ten (10) Business Days after the date the Eligible Liquidity Covenant Default occurred, Borrower
Representative shall deliver evidence satisfactory to Administrative Agent that Borrowers have received Unrestricted Cash in an
amount not less than the amount of the shortfall of Unrestricted Cash relative to the amount required pursuant to subsection
(i) or (ii) above, as applicable (the “Cure Amount”);

 

(3)
Until the Cure Amount is received, Borrower Representative shall not enter into any transactions permitted pursuant to this Agreement
subject to a condition that no Event of Default exists;

 

(4)
During the period commencing on (and including) the date the Eligible Liquidity Covenant Default occurred and ending on the date

Period”), subject to compliance with the foregoing terms, no Event of Default shall be deemed to have occurred, provided
that any Loans requested during the Cure Period shall be made at the sole discretion of Administrative Agent. After an Eligible
Liquidity Covenant Default has been cured in accordance with the foregoing three times during the term of this Agreement, Borrowers
shall cease to have any right to cure any subsequent breaches of Section 6.10(a), and any such breach shall result in an
immediate Event of Default.

 

(b)
Financing Proceeds. If the Second Tranche
Term Loan is made hereunder, the covenants in this subsection (b) shall apply. Borrower Representative shall deliver evidence
satisfactory to Administrative Agent that Loan Parties have received Qualified Financing

[*] during the period commencing on the Closing Date to and including [*];

 

(ii)
[*] (inclusive of any amounts counted for purposes of compliance with clause (i) above) during the period commencing

requirement may be waived by Administrative Agent in writing in its sole and absolute discretion, provided further, that
for purposes of determining compliance with this clause (ii), the amount of Qualified Financing Proceeds received shall
be deemed reduced by an amount equal to (i) the aggregate amount of all Royalty and Milestone Payments (including without limitation
those due to the Cystic Fibrosis Foundation) which are paid, coming due or scheduled or otherwise reasonably expected to come
due by Loan Parties, less projected positive cash flow received Borrowers or their Subsidiaries, on a consolidated basis, received
by a Borrower or such Subsidiary pursuant to any research and development, licensing, collaboration and/or development agreements
giving rise to such Royalty and Milestone Payments, in each case, prior to achievement of the Lenabasum Approval Milestone, which
amount shall be determined based on projections which shall subject to Administrative Agent’s reasonable review and approval
with respect to this clause of Section 6.10(b), provided further that the foregoing shall not require deducting Royalty
and Milestone Payments set forth on Schedule 5 unless the terms of related agreements giving rise to such payments are
modified so as to accelerate the due date of such payments.

a first priority Lien, subject to Permitted Liens in and to the assets of such Subsidiary), and (ii) to pledge all of the direct
or beneficial Equity Interests in such Subsidiary. Any document, agreement, or instrument executed or issued pursuant to this
Section 6.11 shall be a Loan Document.

exercise all rights and remedies available to Collateral Trustee under the Loan Documents or at law or equity, including all remedies
provided under the Code (including disposal of the Collateral pursuant to the terms thereof).

 

Loan
Parties shall assemble the Collateral if Collateral Trustee requests and make it available as Collateral Trustee reasonably designates.
Collateral Trustee may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral,
and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all
expenses incurred. Each Loan Party grants Collateral Trustee a license to enter and occupy any of its premises, without charge,
to exercise any of Collateral Trustee’s rights or remedies. Collateral Trustee is hereby granted a non-exclusive, royalty-free
license or other right to use, without charge, a Loan Party’s labels, Patents, Copyrights, mask works, rights of use of
any name, trade secrets, trade names, Trademarks, and advertising matter, or any similar property as it pertains to the Collateral,
in completing production of, advertising for sale, and selling any Collateral and, in connection with Collateral Trustee’s
exercise of its rights under this Section, a Loan Party’s rights under all licenses and all franchise agreements inure to
Collateral Trustee’s benefit. If, after the acceleration of the Obligations, a Loan Party receives proceeds of Collateral,
such Loan Party shall to deliver such proceeds to Collateral Trustee, for the ratable benefit of Lenders, to be applied to the
Obligations.

 

9.3
Power of Attorney. Each Loan Party hereby irrevocably appoints Collateral Trustee (and any of Collateral Trustee’s partners,
managers, officers, agents or employees) as its lawful attorney-in-fact, with full power of substitution, exercisable upon the
occurrence and during the continuation of an Event of Default, to: (a) send requests for verification of Accounts or notify Account
Debtors of Collateral Trustee’s security interest and Liens in the Collateral; (b) endorse such Loan Party’s name
on any checks or other forms of payment or security; (c) sign such Loan Party’s name on any invoice or bill of lading for
any Account or drafts against Account Debtors schedules and assignments of Accounts, verifications of Accounts, and notices to
Account Debtors; (d) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts and on
terms Administrative Agent or Collateral Trustee determine reasonable; (e) make, settle, and adjust all claims under such Loan
Party’s insurance policies; (f) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim
in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; (g) transfer
the Collateral into the name of Collateral Trustee or a third party as the Code permits; and (h) dispose of the Collateral. Each
Loan Party further hereby appoints Collateral Trustee (and any of Collateral Trustee’s partners, managers, officers, agents
or employees) as its lawful attorney-in-fact, with full power of substitution, regardless of whether or not an Event of Default
has occurred or is continuing to: (i) sign such Loan Party’s name on any documents and other Security Instruments necessary
to perfect or continue the perfection of, or maintain the priority of, Collateral Trustee’s security interest in the Collateral,
(ii) take all such actions which such Loan Party is required, but fails to do under the covenants and provisions of the Loan Documents;
(iii) take any and all such actions as Collateral Trustee may reasonably determine to be necessary or advisable for the purpose
of maintaining, preserving or protecting the Collateral or any of the rights, remedies, powers or privileges of Collateral Trustee
under this Agreement or the other Loan Documents. Collateral Trustee’s foregoing appointment as each Loan Party’s
attorney in fact, and all of Collateral Trustee’s rights and powers, coupled with an interest, are irrevocable until all
Obligations (other than contingent indemnification obligations as to which no claim has been asserted or is known to exist) have
been fully repaid, in cash, and otherwise fully performed and all commitments to make Loans hereunder have been terminated.

 

9.4
Protective Payments. If a Loan Party fails to obtain the insurance called for by Section 6.5 or fails to pay any premium
thereon or fails to pay any other amount which such Loan Party is obligated to pay under this Agreement or any other Loan Document
or which may be required to preserve the Collateral, Collateral Trustee may obtain such insurance or make such payment, and all
amounts so paid by Collateral Trustee are Lender Expenses and immediately due and payable, bearing interest at the then highest
rate applicable to the Obligations, and secured by the Collateral. Collateral Trustee will make reasonable efforts to provide
Borrower Representative with notice of Collateral Trustee obtaining such insurance at the time it is obtained or within a reasonable
time thereafter. No payments by Collateral Trustee are deemed an agreement to make similar payments in the future or Collateral
Trustee’s waiver of any Event of Default.

 

    	22

     

    

 

9.5
Application of Payments and Proceeds Upon Default. If an Event of Default has occurred and is continuing, Collateral Trustee
shall have the right to apply in any order any funds in its possession, whether payments, proceeds realized as the result of any
collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations, for the ratable benefit of Lenders.
Collateral Trustee shall pay any surplus to Borrowers by credit to the Deposit Account designated by Borrowers or as directed
by a court of competent jurisdiction. Borrowers shall remain liable to Collateral Trustee and Lenders for any deficiency. If Collateral
Trustee, as directed by Administrative Agent in Administrative Agent’s good faith business judgment, directly or indirectly,
enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Collateral Trustee may,
at the direction of Administrative Agent, either reduce the Obligations by the principal amount of the purchase price or defer
the reduction of the Obligations until the actual receipt by Collateral Trustee of cash or immediately available funds therefor.

 

9.6
Collateral Trustee’s Liability for Collateral. So long as Collateral Trustee complies with reasonable secured lender
practices regarding the safekeeping of the Collateral in the possession or under the control of Collateral Trustee, Collateral
Trustee shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral;
(c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person.
Loan Parties bear all risk of loss, damage or destruction of the Collateral.

 

9.7
No Waiver; Remedies Cumulative. Any failure by Administrative Agent, Collateral Trustee or any Lender, at any time or times,
to require strict performance by each Loan Party of any provision of this Agreement or any other Loan Document shall not waive,
affect, or diminish any right of Administrative Agent, Collateral Trustee or any Lender thereafter to demand strict performance
and compliance herewith or therewith. Collateral Trustee’s rights and remedies under this Agreement and the other Loan Documents
are cumulative. Collateral Trustee has all rights and remedies provided under the Code, by law, or in equity. Collateral Trustee
or any Lender’s exercise of one right or remedy is not an election and shall not preclude Collateral Trustee or any Lender
from exercising any other remedy under this Agreement or other remedy available at law or in equity, and any waiver of any Event
of Default is not a continuing waiver. Any delay in exercising any remedy is not a waiver, election, or acquiescence.

 

9.8
Demand Waiver. Each Loan Party waives presentment, demand, notice of default or dishonor, notice of payment and nonpayment,
release, compromise, settlement, extension, or renewal of accounts, documents, instruments or chattel paper.

 

9.9
Shares. Each Loan Party recognizes that Collateral Trustee may be unable to effect a public sale of any or all the Shares,
by reason of certain prohibitions contained in federal securities laws and applicable state securities laws or otherwise, and
may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree,
among other things, to acquire such securities for their own account for investment and not with a view to the distribution or
resale thereof. Each Loan Party acknowledges and agrees that any such private sale may result in prices and other terms less favorable
than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed
to have been made in a commercially reasonable manner. Collateral Trustee shall be under no obligation to delay a sale of any
of the Shares for the period of time necessary to permit the issuer thereof to register such securities for public sale under
federal securities laws or under applicable state securities laws, even if such issuer would agree to do so.

 

10.

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 Collateral Trustee from
bringing suit or taking other legal action in any other jurisdiction to realize on the Collateral or any other security for the
Obligations, or to enforce a judgment or other court order in favor of Administrative Agent, Collateral Trustee or any 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.

 

    	24

     

    

 

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, Collateral Trustee or any 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; Release of Collateral. 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 (such date, the “Discharge Date”). So long as Borrowers
have repaid in cash in full 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 Borrowers,
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. Promptly after the
Discharge Date, Administrative Agent and Lenders shall direct Collateral Trustee to deliver evidence of the release of Collateral.

 

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 reasonable 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, provided that if no Event of Default shall have
occurred and be continuing, no Lender shall transfer or assign (other than as part of an assignment of all or a material part
of such Lender’s loan portfolio) its interest in such Lender’s obligations, rights, and benefits under this Agreement
and the other Loan Documents to a distressed debt fund. 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)
Notwithstanding the foregoing, except during the occurrence of an Event of Default or as required by applicable law or any Governmental
Authority having jurisdiction, Administrative Agent and each Lender shall not assign any interest in the Loan Documents to any
Person who in the reasonable estimation of Administrative Agent is a direct competitor of the Loan Parties, whether as an operating
company or direct or indirect parent with voting control over such operating company.

 

    	25

     

    

 

(d)
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 the 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 the 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 the Collateral Trustee 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.

 

12.3
Indemnification. Each Loan Party agrees to indemnify, defend and hold Administrative Agent, Collateral Trustee and each Lender
and their respective directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Lender
(each, an “Indemnified Person”) harmless against: (i) 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 other party in connection with the transactions contemplated by the Loan
Documents; and (ii) all reasonable and documented out-of-pocket losses or expenses (including Lender Expenses) in any way suffered,
incurred, or paid by such Indemnified Person as a result of, following from, consequential to, or arising from transactions among
Administrative Agent, Collateral Trustee, Lenders and Loan Parties (including reasonable and documented out-of-pocket attorneys’
fees and expenses), except for Claims and/or losses to the extent directly caused by such Indemnified Person’s gross negligence
or willful misconduct and Claims and/or losses to the extent arising as a result of actions among Indemnified Persons. 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. 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. If any Person is joined to this Agreement as a Borrower, the following provisions shall apply: 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 or any other applicable law, and (b) any right to require Collateral Trustee to: (i) proceed against any
Borrower or any other person; (ii) proceed against or exhaust any security; or (iii) pursue any other remedy. Collateral Trustee
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 Collateral Trustee 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 a 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 Collateral Trustee, for the ratable benefit of Lenders, for
application to the Obligations, whether matured or unmatured.

 

    	26

     

    

 

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 so long as Administrative Agent provides the Loan Parties with written notice of
such correction and allows the Loan Parties at least ten (10) Business Days to object to such correction. In the event of such
objection, such correction shall not be made except by an amendment signed by both Administrative Agent and the Loan Parties.

 

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 Borrowers, Administrative
Agent, the Required Lenders and Collateral Trustee, 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 provides that Collateral Trustee’s approval is not required. It is agreed that
any change to the definition of “Designated Holder” (and any change to this Agreement that would modify the consent
required pursuant to this sentence) shall require the consent of the Collateral Trustee. 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. 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 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 effective as delivery of an original executed counterpart of such Loan Document.

 

    	27

     

    

 

12.10
Confidentiality; Publicity.

 

(a)
In handling any confidential information, Administrative Agent, Collateral Trustee 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 so long as such parties are bound by
confidentiality terms consistent in all material respects with the terms hereof; (c) as required by law, regulation, subpoena,
or other order and in connection with reporting obligations applicable to Administrative Agent, Collateral Trustee or such Lender,
including pursuant to the Exchange Act, (d) to Administrative Agent, Collateral Trustee or such Lender’s regulators or as
otherwise required in connection with any examination or audit; (e) as Administrative Agent, Collateral Trustee or such Lender
considers reasonably appropriate in connection with the exercise of remedies with respect to the Obligations; and (f) to third-party
service providers of Administrative Agent, Collateral Trustee or such Lender so long as such service providers are bound by confidentiality
terms consistent in all material respects with the terms hereof. Confidential information does not include information that is
either: (i) in the public domain or in Administrative Agent, Collateral Trustee or any Lender’s possession when disclosed
to Administrative Agent, Collateral Trustee or such Lender, as applicable, or becomes part of the public domain (other than as
a result of its disclosure by Administrative Agent, Collateral Trustee or such Lender in violation of this Agreement) after disclosure
to Administrative Agent, Collateral Trustee or such Lender, as applicable; or (ii) disclosed to Administrative Agent, Collateral
Trustee or such Lender by a third party, if Administrative Agent, Collateral Trustee or such 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 party hereto shall publicize or use the other party’s name or logo, or hyperlink to such other parties’ website,
describe the relationship of the parties 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 prior written notice to the party 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 such subject party a reasonable opportunity to review prior to publication, and each party agrees, in connection
with any Publicity Materials proposed by such 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, Collateral Trustee and any 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). Each 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, Collateral
Trustee or any 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.

 

    	28

     

    

 

12.16
Appointment of Collateral Trustee

 

Each
Lender hereby appoints Collateral Trustee to act on behalf of Lenders as collateral agent under this Agreement and the other Loan
Documents, and to hold and enforce any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Obligations,
all in accordance with the terms of the Collateral Trust Agreement. The provisions of this Section 12.16 are solely for
the benefit of Collateral Trustee 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. The Collateral Trustee may resign or be removed or replaced, and a successor Collateral Trustee
may be appointed in accordance with the terms and subject to the conditions of the Collateral Trust Agreement.

 

12.17
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. The provisions of this Section 12.17 are solely for the benefit of Administrative 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, Administrative 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. Administrative
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 Administrative Agent shall be mechanical
and administrative in nature and Administrative Agent shall not 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 Administrative 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 Administrative 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 Administrative Agent
shall incur no liability to any Person by reason of so refraining. Administrative 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 Administrative Agent as a result of Administrative Agent’s acting or refraining
from acting hereunder or under any other Loan Document in accordance with the instructions of Lenders.

 

(c)
Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder by or through any one
or more sub-agent s appointed by Administrative Agent. Administrative 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 and their respective related parties. The exculpatory
provisions of this Section 12.17 shall apply to any such sub-agent and to the related parties of such Administrative Agent
and any such sub-agent. No Administrative 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 Administrative
Agent acted with gross negligence or willful misconduct in the selection of such sub-agents.

 

(d)
Neither Administrative 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, Administrative 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, telecopy, telegram, cable or telex) believed
by it to be genuine and signed or sent by the proper party or parties.

 

    	29

     

    

 

(e)
With respect to its Commitments and Loans hereunder, Administrative 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 Administrative Agent; and the
term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include Administrative Agent in
its individual capacity (to the extent it holds any Obligations owing to Lenders or Commitments hereunder). Administrative 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 Administrative Agent was not Administrative Agent and without any duty to account therefor to Lenders. Administrative 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 Administrative 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 Administrative 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 Administrative 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 Administrative Agent in any way relating to or arising out of this Agreement
or any other Loan Document or any action taken or omitted by Administrative 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 Administrative 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 Administrative
Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including reasonable and documented counsel fees)
incurred by Administrative 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 Administrative Agent is not reimbursed for such expenses
by the Loan Parties.

 

(h)
Administrative Agent may resign at any time by giving not less than thirty (30) days’ prior written notice thereof to Lenders,
Collateral Trustee and Borrower Representative. Upon any such resignation, Lenders shall have the right to appoint a successor
Administrative Agent. If no successor Administrative Agent shall have been so appointed by Lenders and shall have accepted such
appointment within thirty (30) days after Administrative Agent’s giving notice of resignation, then Administrative Agent
may, on behalf of Lenders, appoint a successor Administrative 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 Administrative
Agent has been appointed pursuant to the foregoing, by the 30th day after the date such notice of resignation was given by the
resigning Administrative Agent, such resignation shall become effective and Lenders shall thereafter perform all the duties of
Administrative Agent hereunder until such time, if any, as Lenders appoint a successor Administrative Agent as provided above.
Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative
Agent shall succeed to and become vested with all the rights, powers, privileges and duties of the resigning Administrative Agent.
Upon the earlier of the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent or
the effective date of the resigning Administrative Agent’s resignation, the resigning Administrative 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 Administrative Agent shall continue. After any resigning Administrative Agent’s
resignation hereunder, the provisions of this Section 12.17 shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was Administrative 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 Administrative
Agent unless a successor Administrative Agent is appointed concurrently with such resignation, which successor Administrative
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 Administrative 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 continuation of any Event of Default, with the prior written consent of Administrative 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 Administrative 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 Administrative 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, Administrative Agent shall be entitled to retain for its account all interest accrued on such advance until reimbursed by
the applicable Lender.

 

(k)
If Administrative 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 Administrative Agent from Borrowers and such related payment is not received thereby, then Administrative
Agent will be entitled to recover such amount from such Lender on demand without set-off, counterclaim or deduction of any kind.

 

(l)
If Administrative 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, Administrative Agent will not be required to distribute any portion thereof to any
Lender. In addition, each Lender will repay to Administrative Agent on demand any portion of such amount that Administrative Agent
has distributed to such Lender, together with interest at such rate, if any, as Administrative Agent is required to pay to Borrowers
or such other Person, without set-off, counterclaim or deduction of any kind.

 

(m)
Administrative Agent will use reasonable efforts to provide Lenders with any written notice of Event of Default received by Administrative
Agent from, or delivered by Administrative Agent to, any Loan Party; provided, however, that Administrative 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 Administrative
Agent’s gross negligence or willful misconduct as finally determined by a court of competent jurisdiction.

 

    	31

     

    

 

(n)
Anything in this Agreement or any other Loan Document to the contrary notwithstanding, each Lender hereby agrees with each other
Lender and with Administrative 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 Administrative Agent at the
request of Required Lenders.

 

13.
GUARANTY

 

13.1
Guaranty. Each Guarantor, including Parent, 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.

 

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.

 

    	32

     

    

 

(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 Termination Date. If any amount shall be paid to any Guarantor on account of such
subrogation rights at any time prior to the Termination Date, 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;

 

(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; and

 

(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.

 

    	33

     

    

 

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 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.

 

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 and documented
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.

such lien or would otherwise constitute a default thereunder, provided, that such property will be deemed “Collateral”
hereunder upon the termination and release of such lien;

 

(v)
property that is non-assignable by its terms without the consent of the licensor thereof or another party (but only to the extent

made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined
in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from 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
under this Section 2 or Section 4 of this Schedule 3) the applicable Recipient receives an amount equal to
the sum it would have received had no such deduction or withholding been made.

 

3. Payment
of Other Taxes by the Loan Parties. The Loan Parties shall timely pay to the relevant Governmental Authority in accordance
with applicable law, or at the option of Administrative Agent, timely reimburse it for the payment of, any Other Taxes.

 

4. Indemnification
by the Loan Parties. The Loan Parties shall indemnify each Recipient, within 10 days after demand therefor, for the full amount
of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under Section
2 of this Schedule 3 or this Section 4) payable or paid by such Recipient or required to be 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 Borrower Representative 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.

 

5. Indemnification
by the Lenders. Each Lender shall severally indemnify Administrative Agent and Collateral Trustee, within 10 days after demand
therefor, for (a) any Indemnified Taxes attributable to such Lender (but only to the extent that the Loan Parties have not already
indemnified Administrative Agent or Collateral Trustee for such Indemnified Taxes and without limiting the 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 Collateral Trustee 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 Collateral Trustee, as applicable, shall be conclusive absent manifest error. Each Lender hereby
authorizes Administrative Agent and Collateral Trustee 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 Collateral Trustee, as applicable, to the Lender from
any other source against any amount due to Administrative Agent or Collateral Trustee 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, Borrower Representative 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 Borrower Representative and Administrative Agent, at the time or times reasonably requested by Borrower Representative
or Administrative Agent, such properly completed and executed documentation reasonably requested by Borrower Representative 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 Borrower Representative or Administrative Agent, shall deliver such other documentation
prescribed by applicable law or reasonably requested by Borrower Representative 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 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 Borrower Representative 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 Borrower Representative
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 Borrower Representative 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 Borrower Representative 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 Borrower Representative 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 any Loan Party within the meaning of Section
871(h)(3)(B) of the Internal Revenue Code, or a “controlled foreign corporation” related to any 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 Borrower Representative 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 Borrower Representative 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 Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable
law to permit the applicable 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 Borrower Representative and Administrative Agent at
the time or times prescribed by law and at such time or times reasonably requested by Borrower Representative 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 Borrower Representative or Administrative Agent as may be necessary
for the applicable 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 Borrower Representative 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 Term Loan
or of maintaining its obligation to make any such Term 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 Collateral Trustee 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.

Securities as would permit or facilitate the sale and distribution of all the Registrable Securities in the manner reasonably
requested by the Administrative Agent on behalf of Holders; provided, however, that if the Filing Date falls on a day that
is not a Business Day, such deadline shall be extended to the next Business Day. The Registration Statement shall be on Form S-3

shall be on another appropriate form in accordance with the Securities Act and the rules promulgated thereunder and Parent shall
undertake to register the Registrable Securities on Form S-3 as soon as practicable following the availability of such form, provided
that Parent shall use commercially reasonable efforts to maintain the effectiveness of the Registration Statement then in
effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective
by the SEC). The Registration Statement shall contain the “Plan of Distribution” section in substantially the form
attached hereto as Annex A. Parent shall use commercially reasonable efforts to cause the Registration Statement to be
declared effective under the Securities Act as promptly as practicable after the filing thereof, and, subject to Article 2
hereof, to keep such Registration Statement continuously effective under the Securities Act until such date as is the earlier
of (x) the date when all Registrable Securities covered by such Registration Statement have been sold under such Registration
Statement; or (y) the date on which the Registrable Securities may be immediately be sold pursuant to Rule 144, without volume

Period”). By 9:30 am Eastern Time on the Business Day following the date the Registration
Statement is declared effective, Parent shall file with the SEC in accordance with Rule 424 under the Securities Act the final
prospectus to be used in connection with sales pursuant to such Registration Statement. Lenders acknowledge and agree that securities

2 Registration
Procedures.

 

In
connection with Parent’s registration obligations hereunder, Parent shall:

 

2.1 Prepare
and file with the SEC on or prior to the Filing Date, a Registration Statement on Form S-3 (or if Parent is not then eligible
to register for resale the Registrable Securities on Form S-3 such registration shall be on another appropriate form in accordance
with the Securities Act and the rules and regulations promulgated thereunder) in accordance with the method or methods of distribution
thereof as described on Annex A hereto (except if otherwise reasonably directed by Administrative Agent), and use commercially
reasonable efforts to cause the Registration Statement to become effective and remain effective as provided herein. Notwithstanding
the foregoing or anything otherwise to the contrary herein, Parent may, at any time, delay the filing or delay or suspend the
effectiveness of a Registration Statement or, without suspending such effectiveness, deliver a notice (a “Suspension Notice”)
that instructs any selling Holders not to sell any securities included in the Registration Statement or delay the filing of any
amendment or supplement pursuant to Section 2, if the board of directors of Parent has determined and promptly notifies
the selling Holders in writing that in its reasonable good faith judgment (i) a material event has occurred or is likely to occur
with respect to the Company that has not been publicly disclosed and, if disclosed, would reasonably be expected to materially
and adversely affect Parent and its ability to consummate the registration of the resale of the Registrable Securities or (ii)
such registration would reasonably be expected to materially interfere with any material financing transaction involving Parent
(a “Suspension Period”), by providing the selling Holders with written notice of such Suspension Period and the reasons
therefor. Parent will use its commercially reasonable efforts to provide such notice at least ten (10) Business Days prior to
the commencement of such a Suspension Period; provided, however, that in any event Parent will provide such notice no later than
the commencement of such Suspension Period; provided, further, that in no event will a Suspension Period exceed 60 days and in
no event shall the total number of days subject to a Suspension Period during any consecutive 12-month period exceed 90 days.
Any Suspension Period will not be deemed to end until the Holders have received a notice from Parent stating that such Suspension
Period has ended.

 

    	A-2

     

    

 

2.2 (i)
Prepare and file with the SEC such amendments, including post-effective amendments, to the Registration Statement as may be necessary
to keep the Registration Statement continuously effective (subject to Article 2 hereof) as to the applicable Registrable
Securities for the Effectiveness Period and prepare and file with the SEC such additional Registration Statements, if necessary,
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; and (iii) comply in all material respects
with the provisions of the Securities 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 Parent 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 Parent’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 Parent 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; (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 and 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; (vi) upon the occurrence
of a Suspension Period (items (ii) through and including (vi) being a “Discontinuance Notice”); and (vii) upon the
conclusion of a Suspension Period.

 

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 Parent 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
Parent 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 exhibits (excluding those
previously furnished or incorporated by reference) promptly after the filing of such documents with the SEC, except if such documents
are available on EDGAR.

 

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 Parent 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.

 

    	A-3

     

    

 

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, Parent
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 Parent.

 

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.

 

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 Parent are then listed or traded; provided, however, that nothing in the Section 2.11 shall require Parent 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. Notwithstanding
the foregoing, Parent and any of its subsidiaries may enter into any Change of Control transaction that results in the delisting
of the Common Stock from any such national securities exchange, subject to prepayment as required by the Loan Agreement.

 

2.12 Parent
may require each selling Holder to furnish to Parent information regarding such Holder and the distribution of such Registrable
Securities as is required by law to be disclosed in the Registration Statement, and Parent 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 Parent 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 Discontinuance Notice, 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 (the “Advice”) by Parent 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 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 Parent shall approve the issuance
of a certificate without such legend to the holder of such Securities if the Holder thereof provides Parent with reasonable assurances
that such securities can be sold pursuant to Rule 144. Following the receipt by Parent of such assurances, Parent will, no later
than five trading days following the delivery by a holder to Parent or Parent’s transfer agent of a legended certificate
representing such securities, deliver or cause to be delivered to such Holder a certificate representing such securities that
is free from all restrictive and other legends.

 

    	A-4

     

    

 

2.14 If
after the Filing Date, a Registration Statement is not effective with respect to all of the Registrable Securities and Parent
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 Parent 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) provided, however,
the Parent shall not be required to register any Conversion Shares pursuant to this Section 2.14 that are the subject of
a then-effective Registration Statement. This requirement does not apply to 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 a dividend or reinvestment or similar plan or rights offering,
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 Parent shall include in such registration (i) first, the securities Parent 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 Parent (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 Parent 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 Parent, (iv) Securities Act liability insurance, if Parent so desires such insurance, and (v) fees and expenses
of all other Persons retained by Parent in connection with the consummation of the transactions contemplated by this Agreement,
including, without limitation, Parent’s independent public accountants. In addition, Parent 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 Parent. Parent 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 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 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 Parent 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) the use by a Holder of an outdated or defective
Prospectus after Parent 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 Parent, which consent shall not be
unreasonably withheld. Parent shall notify such Holder promptly of the institution, threat or assertion of any Proceeding of which
Parent 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.

 

    	A-5

     

    

 

4.2 Indemnification
by Holders. Each Holder and its permitted assignees shall, severally and not jointly, indemnify and hold harmless Parent,
its directors, officers, agents and employees, each Person who controls Parent (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 Parent 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) or resulted from the use by such Holder of an outdated or defective Prospectus after Parent has notified
such Holder in writing that the Prospectus is outdated or defective and prior to the receipt by such Holder of written notice
from Parent that use of the applicable prospectus may be resumed or an amended or supplemented Prospectus, but only if and to
the extent that following the receipt of the Advice or the amended or supplemented Prospectus the misstatement or omission giving
rise to such Loss would have been corrected. 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.

 

    	A-6

     

    

 

(c) All
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 in connection with
the conversion of the Conversion Amount.

 

5 Rule
144.

 

As
long as any Holder owns any Registrable Securities, Parent 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 Parent
after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange Act (other than reports on Form 8-K).

 

6 Miscellaneous.

 

6.1 Remedies.
In the event of a breach by Parent or by a Holder, of any of their obligations under this Agreement, each Holder or Parent, 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 seek specific performance of its rights under this Agreement. Parent 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.

 

    	A-7

     

    

 

6.2 Assignment
of Registration Rights. The rights of each Holder hereunder, including the right to have Parent 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 Parent within a reasonable time after such assignment, (ii) Parent 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 Parent receives the written notice contemplated by clause (ii) of this Section,
the transferee or assignee agrees in writing with Parent 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 Parent, Parent may
deliver all notices, materials and other correspondence that is permitted or required to be delivered to all or any Holders to
Administrative Agent in accordance with Section 10 of the Agreement, and Administrative Agent shall promptly deliver the same
to Holders.

 

    	A-8

     

    

 

PLAN
OF DISTRIBUTION

 

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 SECs
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 SEC 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 SECs 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 SECs
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
SECs or discounts under the Securities Act. In no event shall any broker-dealer receive fees, SEC and markups which, in the aggregate,
would exceed eight percent (8%). Each Selling Stockholder has informed Parent that it does not have any written or oral agreement
or understanding, directly or indirectly, with any person to distribute the Common Stock.

 

    	A-9

     

    

 

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 SEC. 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
with an agreement between us and the Selling Stockholders. We may be indemnified by the Selling Stockholders against civil liabilities,
including liabilities under the Securities Act, that may arise from any written information furnished to us by the Selling Stockholders
specifically for use in this prospectus, in accordance with the related registration rights agreement, or we may be entitled to
contribution.

 ***********

 

The
undersigned agrees to promptly notify the Company of any inaccuracies or changes in the information provided herein that may occur
subsequent to the date hereof and prior to the effective date of any applicable Registration Statement filed pursuant to the Agreement.

 

By
signing below, the undersigned consents to the disclosure of the information contained herein in its answers to Items 1 through
7 and the inclusion of such information in each Registration Statement filed pursuant to the Agreement and each related Prospectus.
The undersigned understands that such information will be relied upon by the Company in connection with the preparation or amendment
of any such Registration Statement and the related Prospectus.

 

By
signing below, the undersigned acknowledges that it understands its obligation to comply, and agrees that it will comply, with
the provisions of the Exchange Act and the rules and regulations thereunder, particularly Regulation M. The undersigned also acknowledges
that it understands that the answers to this Questionnaire are furnished for use in connection with Registration Statements filed
pursuant to the Agreement and any amendments or supplements thereto filed with the SEC pursuant to the Securities Act.

 

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.
