Item 1.01 Entry into a Material Definitive Agreement.

The information provided under Item 3.02 of this
Current Report on Form 8-K with respect to the execution of the Transaction Agreement (as defined in Item 3.02 hereof), including the
issuance by Clean Energy Fuels Corp. (the “Company”) to Amazon.com NV Investment Holdings LLC (“Amazon Holdings”),
a subsidiary of Amazon.com, Inc. (“Amazon”), of the Warrant (as defined in Item 3.02 hereof), is incorporated by reference
into this Item 1.01.

 

Item 3.02 Unregistered Sales of Equity Securities.

On April 16, 2021, in connection with
execution of a Project Addendum to Fuel Pricing Agreement with Amazon Logistics, Inc., a subsidiary of Amazon (“Fuel
Agreement”), the Company entered into a Transaction Agreement with Amazon (the “Transaction
Agreement”), pursuant to which, among other things, the Company issued to Amazon Holdings a warrant (the
“Warrant”) to purchase up to an aggregate of 53,141,755 shares (the “Warrant Shares”) of common stock, par
value $0.0001 per share, of the Company (the “Common Stock”) subject to adjustment and vesting in accordance with the
terms and conditions set forth in the Warrant.

Pursuant to the terms of the Warrant, the Warrant
Shares vest in multiple tranches. The first tranche of 13,283,445 Warrant Shares vested in connection with the execution of the Fuel Agreement.
Subsequent tranches will vest over time based on discretionary fuel purchases by Amazon and its affiliates, up to a total of $500 million,
pursuant to the Fuel Agreement. In addition, in the event of certain acquisition transactions involving the Company under conditions as
set forth in the Warrant, all unvested Warrant Shares will automatically vest and become exercisable. Subject to vesting and certain conditions
set forth therein, the Warrant may be exercised, in whole or in part, at any time before April 16, 2031 at an exercise price of $13.49
per share, which was determined based on the 30-day volume-weighted average price for the Common Stock as of April 15, 2021. Both the exercise
price and the number of Warrant Shares subject to purchase pursuant to the Warrant are subject to customary anti-dilution adjustments,
including a requirement that in the event the Company issues, or commits to issue, any equity securities in a financing to raise capital
within six (6) months after the issuance of the Warrant, the number of Warrant Shares will be increased to a number of shares that would
represent 19.999% of the outstanding Common Stock on a fully diluted basis after giving effect to such financing.

Pursuant to the terms of the Transaction Agreement,
the Company is required to use its commercially reasonable efforts to obtain the approval of its stockholders with respect to the issuance
of Warrant Shares in excess of 50,595,531 shares of Common Stock (such number of shares, the “Share Cap”), as may be required
pursuant to the Nasdaq Global Select Market’s (“Nasdaq”) Listing Rule 5635(b) (the “Stockholder Approval”). Until
the Stockholder Approval is obtained, Nasdaq Listing Rule 5635(b) may restrict the issuance of shares of Common Stock exceeding
the Share Cap pursuant to, and upon the exercise of, the Warrant. In connection with obtaining the Stockholder Approval and pursuant to
the Transaction Agreement, the Company agreed to file a proxy statement and hold a meeting of the Company’s stockholders as promptly
as practicable to obtain the Stockholder Approval. To the extent the Stockholder Approval is not obtained at such stockholder meeting,
at Amazon’s request, the Company is required to cause another stockholder meeting to be held every twelve (12) months until either
the Stockholder Approval is obtained, or the term of the Warrant expires. The Company intends to seek the Stockholder Approval at its
2021 annual meeting of stockholders, which is scheduled to be held in June 2021.

Amazon Holdings may not exercise the Warrant to
the extent such exercise would cause Amazon Holdings to beneficially own more than 4.999% of the number of shares of Common Stock outstanding
immediately after giving effect to such exercise (excluding any unvested portion of the Warrant) (the “Beneficial Ownership Limitation”).
Amazon Holdings may, however, waive or modify the Beneficial Ownership Limitation by providing written notice to the Company sixty-one
(61) days before such waiver or modification becomes effective (or immediately upon written notice to the Company to the extent the Company
is subject to certain acquisition transactions pursuant to a tender or exchange offer).

Under the Transaction Agreement, the Company also
granted Amazon customary registration rights with respect to the Warrant Shares. The Transaction Agreement also limits Amazon’s
ability to transfer the Warrant to certain unaffiliated third parties and imposes customary standstill limitations on Amazon if, and so
long as, Amazon and its subsidiaries beneficially own at least 5% of the outstanding Common Stock.

The Warrant and the Warrant Shares have not been
registered under the Securities Act of 1933 (as amended, the “Securities Act”) or under any state securities law and were
offered and issued, as applicable, in reliance upon the exemption from registration requirements of the Securities Act set forth in Section
4(a)(2) of the Securities Act. The Company did not engage in a general solicitation or advertising regarding the issuance of the Warrant. Amazon
has represented to the Company its intention to acquire the Warrant and Warrant Shares for investment purposes only and not with a view
toward their resale, distribution or other disposition in violation of the Securities Act or any applicable state securities laws, and
appropriate legends will be affixed to the Warrant and the Warrant Shares.

This Item 3.02 contains only a brief description
of the material terms of the Transaction Agreement and the Warrant and does not purport to be a complete description of the rights and
obligations of the parties thereunder, and such descriptions are qualified in their entirety by reference to the full text of the
Transaction Agreement and Warrant, which are attached hereto as Exhibit 10.27 and Exhibit 4.4, respectively.

 

Item 7.01 Regulation FD Disclosure.

On April 19, 2021, the Company issued a press release
announcing the execution of the Fuel Agreement and the Transaction Agreement and issuance of the Warrant. A copy of such press release
is attached hereto as Exhibit 99.1

As provided in General Instruction B.2 of Form
8-K, the information in this Item 7.01 of this Current Report on Form 8-K shall not be deemed “filed” for purposes of Section
18 of the Securities Exchange Act of 1934 (as amended, the “Exchange Act”), or otherwise subject to the liabilities of that
section, nor shall it be incorporated by reference into any registration statement or other document filed under the Securities Act or
the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

 

Item 8.01 Other Events.

 

A significant portion of the outstanding
Common Stock is Beneficially Owned by two equityholders, each of which may have interests that differ from the Company’s other stockholders
and which now or in the future may be able to influence the Company’s corporate decisions, including a change of control.

 

After giving effect to the
issuance of the Warrant, Total Marketing Services, S.E. (“TMS”), a wholly owned subsidiary of Total, beneficially owns 20.1%
of the outstanding Common Stock (excluding 7,898,021 shares of Common Stock that are the subject of a voting agreement, dated May 9,
2018, among TMS, the Company and all of the Company’s then-directors and officers), and the Warrant is currently exercisable by
Amazon Holdings for Warrant Shares representing 4.999% of the outstanding Common Stock. Subject to vesting of the Warrant and receipt
of the Stockholder Approval, the Warrant will be exercisable for up to 19.999% of the outstanding Common Stock on a fully diluted basis
(determined at the time of issuance of the Warrant), subject to certain anti-dilution provisions, and Amazon Holding’s beneficial
ownership will initially be contractually limited to the Beneficial Ownership Limitation unless Amazon Holdings gives the Company sixty
one (61) days’ notice that it is waiving such limitation.

Total or other large stockholders
may be able to influence or control matters requiring approval by our stockholders, including the election of directors and mergers, acquisitions,
or other extraordinary transactions. Amazon, through ownership by Amazon Holdings, could become a large stockholder if the Warrant were
to vest further through additional fuel purchases from the Company pursuant to the Fuel Agreement, and Amazon Holdings were to exercise
the Warrant to purchase vested Warrant Shares and waive the Beneficial Ownership Limitation. Large stockholders may have interests that
differ from other stockholders and may vote or otherwise act in ways with which the Company or other stockholders disagree or that may
be adverse to other stockholders’ interests. A concentration of stock ownership may also have the effect of delaying, preventing
or deterring a change of control of the Company, which could deprive the Company’s stockholders of an opportunity to receive a premium
for their shares of Common Stock as part of a sale of the Company and could affect the market price of Common Stock. Conversely, such
a concentration of stock ownership may facilitate a change of control under terms other stockholders may not find favorable or at a time
when other stockholders may prefer not to sell.

2

Sales of large amounts of
Common Stock by large stockholders, or the perception that such sales may occur, could cause the market price of the Common Stock to decline,
regardless of the state of the Company’s business. The Common Stock held by TMS and the Common Stock underlying the Warrants held
by Amazon may be sold in the public market under Rule 144 or in registered sales or offerings pursuant to registration rights held by
each stockholder.

Expected Impact on
Financial Results
.

The issuance of the Warrant
described in this Current Report on Form 8-K is expected to result in non-cash contra revenue charges of approximately $76 million, which
will impact the Company’s operating income for the year ended December 31, 2021. As a result, the Company plans to revise its previously
published guidance regarding GAAP net income (loss) attributable to the Company for 2021 and expects to publish updated guidance for
2021, together with its announcement of financial results for the first quarter of 2021, in May 2021.

Capital Expenditures.

We expect to deploy $45 million to $60 million in capital expenditures to build fueling stations that will support RNG fueling volume
contracted to Amazon during the year ended December 31, 2021.

and until the approvals required pursuant to the applicable Nasdaq Listing Rules, including but not limited to Nasdaq Listing Rule 5635(b),
are obtained. The Warrant Shares and Exercise Price are subject to adjustment and/or may be supplemented by or converted into other Equity
Securities as provided herein, and all references to “Common Stock,” “Warrant Shares,” and “Exercise Price”
herein shall be deemed to include any such adjustment, supplement, and/or conversion or series of adjustments, supplements, or conversions.

(i)
Promptly following the occurrence of a Vesting Event, the Company shall deliver to the Warrantholder a Notice of Vesting Event
in the form attached as Annex A hereto; provided that neither the delivery, nor the failure of the Company to deliver, such
Notice of Vesting Event shall affect or impair the Warrantholder’s rights or the Company’s obligations hereunder.

(ii)
Subject to (A) Section 2, Section 11(v), and Section 12, (B) the approvals required pursuant to the applicable
Nasdaq Listing Rules, including but not limited to Nasdaq Listing Rule 5635(b), and (C) compliance with the Antitrust Laws (including

the right to purchase Warrant Shares represented by this Warrant is exercisable, in whole or in part by the Warrantholder, at any time
or from time to time, from and after the applicable Vesting Event, but in no event later than 5:00 p.m., Seattle time, on April 16, 2031
(subject to extension pursuant to Section 3(iii), such time as extended if applicable, the “Expiration Time
and such period from and after the applicable Vesting Event through the Expiration Time, the “Exercise Period”), by
(a) the surrender of this Warrant and the Notice of Exercise attached as Annex B hereto, duly completed and executed on behalf
of the Warrantholder, to the Company in accordance with Section 16 (or such other office or agency of the Company in the United
States as it may designate by notice to the Warrantholder in accordance with Section 16 hereof (the “Designated Company
Office
”)), and (b) payment of the Exercise Price for the Warrant Shares thereby purchased by, at the sole election of the Warrantholder,
either: (i) tendering in cash, by certified or cashier’s check payable to the order of the Company, or by wire transfer of immediately
available funds to an account designated by the Company (such manner of exercise, a “Cash Exercise”) or (ii) without
payment of cash, by reducing the number of Warrant Shares obtainable upon the exercise of this Warrant (either in full or in part, as
applicable) and payment of the Exercise Price in cash so as to yield a number of Warrant Shares obtainable upon the exercise of this Warrant
(either in full or in two or more parts, as applicable) equal to the product of (x) the number of Warrant Shares issuable upon the exercise
of this Warrant (either in full or in two or more parts, as applicable) (if payment of the Exercise Price were being made in cash) and
(y) the Cashless Exercise Ratio (such manner of exercise, a “Cashless Exercise”); provided that such product
shall be rounded to the nearest whole Warrant Share.

Portions of this Warrant identified by [*] have been omitted pursuant
to a request for confidential treatment and have been separately filed with the SEC.

(iii)
Notwithstanding the foregoing, if at any time during the Exercise Period the Warrantholder has not exercised this Warrant in full
as a result of there being insufficient Warrant Shares available for issuance or the lack of any required regulatory, corporate or other
approval (including, for the avoidance of doubt, any Requisite Stockholder Approval and approval required under the Antitrust Laws (including
the Initial Antitrust Clearance), if so applicable) (collectively, the “Exercise Conditions”), the Expiration Time
shall be extended until sixty (60) days after such date as the Warrantholder is able to acquire all of the vested Warrant Shares without
violating any Exercise Conditions.

(iv)
If the Warrantholder does not exercise this Warrant in its entirety, the Warrantholder shall be entitled to receive from the Company,
upon request, a new warrant of like tenor in substantially identical form for the purchase of that number of Warrant Shares equal to the
difference between the number of Warrant Shares and the number of Warrant Shares as to which this Warrant is so exercised.

(v)
The Company shall either (a) maintain itself or (b) cause its transfer agent to maintain, in each case, books for the original
issuance and the transfer and exercises of the Warrant issuable in connection therewith, in each case in accordance with the terms hereof
in book-entry form. If the Company maintains books for the Warrant, then (I) the Company agrees that it will accept instructions from
the Warrantholder for the transfer and exercise of the Warrants, to the extent permitted in accordance with the terms of the Warrant and
the Transaction Agreement, and (II) the Company shall not require the delivery of the original Warrant or any copy thereof, in each case
in certificated form, in connection with the transfer or exercise thereof. The Company shall be responsible for all fees and expenses
with respect to maintaining the Warrant in book-entry form.

(vi)
This Warrant, including with respect to its cancelation, is subject to the terms and conditions of the Transaction Agreement. Without
affecting in any manner any prior exercise of this Warrant (or any Warrant Shares previously issued hereunder), if (a) the Transaction
Agreement is terminated in accordance with Section 8.1 thereof or (b) the Warrantholder delivers to the Company a written, irrevocable
commitment not to exercise this Warrant, then the Company shall have no obligation to issue, and the Warrantholder shall have no right
to acquire, the unvested portion of any Warrant Shares under this Warrant.

4.
Issuance of Warrant Shares; Authorization; Listing; Cash Settlement.

(i)
The Company shall issue a certificate or certificates or book-entry or book-entries for the Warrant Shares issued upon exercise
of this Warrant on or before the second (2nd) Business Day following the date of exercise of this Warrant (the “Share Delivery
Date
”) in accordance with its terms in the name of the Warrantholder and shall deliver such certificate or certificates to the
Warrantholder. If the Warrant Shares issued upon any exercise are registered under the Securities Act, in lieu of issuing a physical share
certificate or book-entry, the Company’s transfer agent shall use the DTC Fast Automated Securities Transfer Program to credit such
aggregate number of Warrant Shares to which the Warrantholder is entitled pursuant to such exercise to the Warrantholder’s or its
designee’s balance account with DTC through its DWAC system. The Company shall be responsible for all fees and expenses of its transfer
agent and all fees and expenses with respect to the issuance of Warrant Shares via DTC, if any, including without limitation for same
day processing.

(ii)
The Company’s obligations to issue and deliver Warrant Shares in accordance with the terms and subject to the conditions
hereof are absolute and unconditional, irrespective of any action or inaction by the Warrantholder to enforce the same, any waiver or
consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any
setoff, counterclaim, recoupment, limitation, or termination; provided, however, that the Company shall not be required
to deliver Warrant Shares with respect to an exercise prior to the Warrantholder’s delivery of the associated exercise price (or
notice of cashless exercise).

(iii)
The Company hereby represents and warrants that any Warrant Shares issued upon the exercise of this Warrant in accordance with
the provisions of Section 3 will be validly issued, fully paid and nonassessable and free of any liens or encumbrances (other than
liens or encumbrances created by the Transaction Documents, transfer restrictions arising as a matter of U.S. federal securities laws
or created by or at the direction of the Warrantholder or any of its Affiliates). Following the issuance of any Warrant Shares, the Company
shall register such issuance in book-entry form in the name of the Warrantholder. The Warrant Shares so issued shall be deemed for all
purposes to have been issued to the Warrantholder as of the close of business on the date on which this Warrant and payment of the Exercise
Price are delivered to the Company in accordance with the terms of this Warrant, notwithstanding that the stock transfer books of the
Company may then be closed or certificates representing such Warrant Shares may not be actually delivered on such date or credited to
the Warrantholder’s DTC account, as the case may be. The Company shall use commercially reasonable efforts to obtain the Requisite
Stockholder Approval and at all times reserve and keep available, out of its authorized but unissued Warrant Shares, solely for the purpose
of providing for the exercise of this Warrant, the aggregate Warrant Shares then issuable upon exercise of this Warrant in full (disregarding
whether or not this Warrant is exercisable by its terms at any such time).

(iv)
The Company shall, at its sole expense, procure, subject to issuance or notice of issuance, the listing of any Warrant Shares issuable
upon exercise of this Warrant on the Principal Trading Market on which such same class of Equity Securities are then listed or traded,
promptly after such Warrant Shares are eligible for listing thereon.

5.
No Fractional Shares or Scrip. No fractional Warrant Shares or other Equity Securities or scrip representing fractional
Warrant Shares or other Equity Securities shall be issued upon any exercise of this Warrant. In lieu of any fractional share to which
a Warrantholder would otherwise be entitled, the fractional Warrant Shares or other Equity Securities shall be rounded up to the next
whole Warrant Share or other Equity Securities, and the Warrantholder shall be entitled to receive such rounded up number of Warrant Shares
or other Equity Securities.

6.
No Rights as Shareholders; Transfer Books. Without limiting in any respect the provisions of the Transaction Agreement and
except as otherwise provided by the terms of this Warrant, this Warrant does not entitle the Warrantholder to (i) consent to any action
of the shareholders of the Company, (ii) receive notice of or vote at any meeting of the shareholders, (iii) receive notice of any other
proceedings of the Company, (iv) subject to Section 11(iii) below, receive cash dividends or similar distributions, and (v) exercise
any other rights whatsoever, in any such case, as a stockholder of the Company prior to the date of exercise of this Warrant.

7.
Charges, Taxes, and Expenses. Issuance of this Warrant and issuance of certificates for Warrant Shares to the Warrantholder
upon the exercise of this Warrant shall be made without charge to the Warrantholder for any issue, registration or transfer tax, assessment
or similar governmental charge (other than any such taxes, assessments or charges in respect of any transfer occurring contemporaneously
therewith) or other incidental expense in respect of the issuance of such certificates, all of which taxes, assessments, charges and expenses
shall be paid by the Company.

8.
Transfer/Assignment.

(i)
This Warrant may be transferred only in accordance with the terms of the Transaction Agreement. Subject to compliance with the
first sentence of this Section 8(i) and the legend as set forth on the cover page of this Warrant and the terms of the Transaction
Agreement, this Warrant and all rights hereunder are transferable, in whole or in part, upon the books of the Company by the registered
holder hereof in person or by duly authorized attorney, and a new Warrant shall be made and delivered by the Company, of the same tenor
and date as this Warrant but registered in the name of one or more transferees, upon surrender of this Warrant, duly endorsed, to the
Designated Company Office. If the transferring holder does not transfer the entirety of its rights to purchase all Warrant Shares hereunder,
such holder shall be entitled to receive from the Company a new Warrant in substantially identical form for the purchase of that number
of Warrant Shares as to which the right to purchase was not transferred. All expenses (other than stock transfer taxes) and other charges
payable in connection with the preparation, execution and delivery of the new Warrant pursuant to this Section 8 shall be paid
by the Company.

10

Portions of this Warrant identified by [*] have
been omitted pursuant to a request for confidential treatment and have been separately filed with the SEC.

(ii)
If and for so long as required by the Transaction Agreement, any Warrant certificate or book-entry issued hereunder shall contain
a legend as set forth in Section 4.2 of the Transaction Agreement.

9.
Exchange and Registry of Warrant. This Warrant is exchangeable, subject to applicable securities laws, upon the surrender
hereof by the Warrantholder to the Company, for a new warrant or warrants of like tenor and representing the right to purchase the same
aggregate number of Warrant Shares. The Company shall maintain, or cause its transfer agent to maintain, a registry showing the name and
address of the Warrantholder as the registered holder of this Warrant. This Warrant may be surrendered for exchange or exercise, in accordance
with its terms, at the Designated Company Office, and the Company shall be entitled to rely in all respects, prior to written notice to
the contrary, upon such registry.

10.
Non-Business Day Extension. If the last or appointed day for the taking of any action or the expiration of any right required
or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding day
that is a Business Day.

11.
Adjustments and Other Rights. The Exercise Price and Warrant Shares issuable upon exercise of this Warrant shall be subject
to adjustment from time to time as follows; provided that if more than one subsection of this Section 11 is applicable to
a single event, the subsection shall be applied that produces the largest adjustment and no single event shall cause an adjustment under
more than one subsection of this Section 11 so as to result in duplication.

(i)
Stock Splits, Subdivisions, Reclassifications, or Combinations. If the Company shall at any time or from time to time (a)
declare, order, pay, or make a dividend or make a distribution on its Common Stock in additional shares of Common Stock, (b) split, subdivide,
or reclassify the outstanding shares of Common Stock into a greater number of shares, or (c) combine or reclassify the outstanding shares
of Common Stock into a smaller number of shares, the number of Warrant Shares issuable upon exercise of this Warrant at the time of the
record date for such dividend or distribution or the effective date of such split, subdivision, combination, or reclassification shall
be proportionately adjusted so that the Warrantholder immediately after such record date or effective date, as the case may be, shall
be entitled to purchase the number of shares of Common Stock which such holder would have owned or been entitled to receive in respect
of the shares of Common Stock subject to this Warrant after such date had this Warrant been exercised in full immediately prior to such
record date or effective date, as the case may be (disregarding whether or not this Warrant had been exercisable by its terms at such
time). In the event of such adjustment, the Exercise Price in effect at the time of the record date for such dividend or distribution
or the effective date of such split, subdivision, combination, or reclassification shall be immediately adjusted to the number obtained
by dividing (x) the product of (1) the number of Warrant Shares issuable upon the exercise of this Warrant in full before the adjustment
determined pursuant to the immediately preceding sentence (disregarding whether or not this Warrant was exercisable by its terms at such
time) and (2) the Exercise Price in effect immediately prior to the record or effective date, as the case may be, for the dividend, distribution,
split, subdivision, combination, or reclassification giving rise to such adjustment by (y) the new number of Warrant Shares issuable upon
exercise of the Warrant in full determined pursuant to the immediately preceding sentence (disregarding whether or not this Warrant is
exercisable by its terms at such time).

11

Portions of this Warrant identified by [*] have
been omitted pursuant to a request for confidential treatment and have been separately filed with the SEC.

(ii)
Financing. If the Company shall at any time or from time to time after the Issue Date but on or prior to the six month anniversary
of the Issue Date issue or commit pursuant to a definitive agreement to issue its Equity Securities in a financing for capital raising
purposes (“Financing”), then the number of Warrant Shares issuable upon the exercise of this Warrant held by the Warrantholder
shall be increased to a number equal to 19.999% of the outstanding shares of Common Stock on a fully diluted basis after giving effect
to such Financing, including for avoidance of doubt, any Equity Securities that may be purchased upon exercise of any Person’s option
to purchase additional Equity Securities in connection with such Financing. Any adjustment made pursuant to this Section 11(ii)
shall become effective immediately after the later to occur of (1) consummation of the Financing or (2) the six month anniversary of the
Issue Date. For the avoidance of doubt, no increase to the Exercise Price or decrease in the number of Warrant Shares issuable upon exercise
of this Warrant shall be made pursuant to this Section 11(ii).

(iii)
Distributions. If the Company, at any time while this Warrant is outstanding, declares or makes any dividend or distributes
to holders of shares of Common Stock (and not to the Warrantholder) evidences of its indebtedness or assets (including cash and cash dividends
or property) or rights or warrants to subscribe for or purchase any security (including, without limitation, any distribution of cash,
stock, or other securities, property, or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of
arrangement, or other similar transaction other than dividends or distributions pursuant to Section 11(i)) (collectively, a “Distribution”),
then the Warrantholder will be entitled to participate in such Distribution and be deemed to have exercised, and be the holder of, Warrant
Shares that are vested as of immediately before the record date of such Distribution. For clarity, Warrantholder will not be entitled
to participate in any Distribution in connection with any Warrant Shares that are not vested as of immediately before the record date
of such Distribution.

(iv)
Repurchases. If the Company shall at any time or from time to time effect Repurchases, then the Exercise Price shall be
reduced to the price determined by multiplying the Exercise Price in effect immediately prior to the date of first purchase of Equity
Securities comprising such Repurchases by a fraction of which the numerator shall be (a) the product of (1) the number of shares of Common
Stock outstanding immediately prior to the first purchase of Equity Securities comprising such Repurchases and (2) the Market Price per
share of Common Stock on the Trading Day immediately preceding the first public announcement by the Company of the intent to effect such
Repurchases, minus (b) the Assumed Payment Amount, and of which the denominator shall be the product of (X) the number of shares of Common
Stock outstanding immediately prior to the first purchase of Equity Securities comprising such Repurchases minus the number of shares
of Common Stock so repurchased and (Y) the Market Price per share of Common Stock on the Trading Day immediately preceding the first public
announcement by the Company of the intent to effect such Repurchases. In such event, the number of Warrant Shares issuable upon the exercise
of this Warrant shall be increased to the number obtained by multiplying such number of Warrant Shares by the quotient of (A) the Exercise
Price in effect immediately prior to the first purchase of Equity Securities comprising such Repurchases divided by (B) the new Exercise
Price determined in accordance with the immediately preceding sentence. For the avoidance of doubt, no increase to the Exercise Price
or decrease in the number of Warrant Shares issuable upon exercise of this Warrant shall be made pursuant to this Section 11(iv).
For purposes of the foregoing, the “Assumed Payment Amount” with respect to any Repurchases shall mean the aggregate
Market Price (in the case of securities) and/or Fair Market Value (in the case of cash and/or any other property), as applicable, as of
such Repurchases, of the aggregate consideration paid to effect such Repurchases.

12

Portions of this Warrant identified by [*] have
been omitted pursuant to a request for confidential treatment and have been separately filed with the SEC.

(v)
Acquisition Transactions. In case of any Acquisition Transaction or reclassification of Common Stock (other than a reclassification
of Common Stock subject to adjustment pursuant to Section 11(i)), notwithstanding anything to the contrary contained herein, (a)
the Company shall notify the Warrantholder in writing of such Acquisition Transaction or reclassification as promptly as practicable (but
in no event later than ten Business Days prior to the effectiveness thereof), (b) the Warrant Shares shall immediately vest fully and
become nonforfeitable, and subject to clause (c) below, become immediately exercisable upon consummation of such Acquisition Transaction
or reclassification, and (c) solely in the event of an Acquisition Transaction that is a Business Combination or a reclassification, the
Warrantholder’s right to receive Warrant Shares upon exercise of this Warrant shall be converted, effective upon the occurrence
of such Business Combination or reclassification, into the right to exercise this Warrant to acquire the number of shares of stock or
other securities or property (including cash) that the shares of Common Stock issuable (at the time of such Business Combination or reclassification)
upon exercise of this Warrant immediately prior to such Business Combination or reclassification would have been entitled to receive upon
consummation of such Business Combination or reclassification. In determining the kind and amount of stock, securities, or the property
receivable upon exercise of this Warrant upon and following adjustment pursuant to this paragraph, if the holders of Common Stock have
the right to elect the kind or amount of consideration receivable upon consummation of such Business Combination, then the Warrantholder
shall have the right to make the same election upon exercise of this Warrant with respect to the number of shares of stock or other securities
or property which the Warrantholder shall receive upon exercise of this Warrant. The Company, or the Person or Persons formed by the applicable
Business Combination or reclassification, or that acquire(s) the applicable shares of Common Stock, as the case may be, shall make lawful
provisions to establish such rights and to provide for such adjustments that, for events from and after such Business Combination or reclassification,
shall be as nearly equivalent as possible to the rights and adjustments provided for herein, and the Company shall not be a party to or
permit any such Business Combination or reclassification to occur unless such provisions are made as a part of the terms thereof.

(vi)
Rounding of Calculations; Minimum Adjustments. All calculations under this Section 11 shall be made to the nearest
one-tenth (1/10th) of a cent or to the nearest one-hundredth (1/100th) of a share, as the case may be. Any provision of this Section
11
to the contrary notwithstanding, no adjustment in the Exercise Price or the number of Warrant Shares into which this Warrant is
exercisable shall be made if the amount of such adjustment would be less than $0.01 or one-tenth (1/10th) of a share of Common Stock,
but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any
subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate $0.01 or one-tenth
(1/10th) of a share of Common Stock, or more.

13

Portions of this Warrant identified by [*] have
been omitted pursuant to a request for confidential treatment and have been separately filed with the SEC.

(vii)
Timing of Issuance of Additional Securities Upon Certain Adjustments. In any event in which (a) the provisions of this Section
11
shall require that an adjustment (the “Subject Adjustment”) shall become effective immediately after a record
date (the “Subject Record Date”) for an event and (b) the Warrantholder exercises this Warrant after the Subject Record
Date and before the consummation of such event, the Company may defer until the consummation of such event issuing to such Warrantholder
the incrementally additional shares of Common Stock or other property issuable upon such exercise by reason of the Subject Adjustment;
provided, however, that the Company upon request shall promptly deliver to such Warrantholder a due bill or other appropriate
instrument evidencing such Warrantholder’s right to receive such additional shares (or other property, as applicable) upon the consummation
of such event.

(viii)
Statement Regarding Adjustments. Whenever the Exercise Price or the Warrant Shares into which this Warrant is exercisable
shall be adjusted as provided in Section 11, the Company shall promptly prepare a statement showing in reasonable detail the
facts requiring such adjustment and the Exercise Price that shall be in effect and the Warrant Shares into which this Warrant shall be
exercisable after such adjustment, and cause a copy of such statement to be delivered to the Warrantholder as promptly as practicable
after the event giving rise to the adjustment.

(ix)
Notice of Adjustment Event. In the event that the Company shall propose to take any action of the type described in this
Section 11 (but only if the action of the type described in this Section 11 would result in an adjustment in the Exercise
Price or the Warrant Shares into which this Warrant is exercisable or a change in the type of securities or property to be delivered upon
exercise of this Warrant), the Company shall provide written notice to the Warrantholder, which notice shall specify the record date,
if any, with respect to any such action and the approximate date on which such action is to take place. Such notice shall also set forth
the facts with respect thereto as shall be reasonably necessary to indicate the effect on the Exercise Price and the number, kind, or
class of shares or other securities or property which shall be deliverable upon exercise of this Warrant. In the case of any action which
would require the fixing of a record date, such notice shall be given at least ten days prior to the date so fixed. In case of all other
actions, such notice shall be given at least ten days prior to the taking of such proposed action unless the Company reasonably determines
in good faith that, given the nature of such action, the provision of such notice at least ten days in advance is not reasonably practicable
from a timing perspective, in which case such notice shall be given as far in advance prior to the taking of such proposed action as is
reasonably practicable from a timing perspective.

(x)
Adjustment Rules. Any adjustments pursuant to this Section 11 shall be made successively whenever an event referred
to herein shall occur. If an adjustment in the Exercise Price made hereunder would reduce the Exercise Price to an amount below par value
of the Common Stock, then such adjustment in the Exercise Price made hereunder shall reduce the Exercise Price to the par value of the
Common Stock.

14

Portions of this Warrant identified by [*] have
been omitted pursuant to a request for confidential treatment and have been separately filed with the SEC.

(xi)
No Impairment. The Company shall not, by amendment of its certificate of incorporation, bylaws, or any other organizational
document, or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue, or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the
Company, but shall at all times in good faith assist in the carrying out of all the provisions of this Warrant. In furtherance and not
in limitation of the foregoing, the Company shall not take or permit to be taken any action that would (a) increase the par value of any
shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect or (b) entitle the Warrantholder
to an adjustment under this Section 11 if the total number of shares of Common Stock issuable after such action upon exercise of
this Warrant in full (disregarding whether or not this Warrant is exercisable by its terms at such time), together with all shares of
Common Stock then outstanding and all shares of Common Stock then issuable upon the exercise in full of any and all outstanding Equity
Securities (disregarding whether or not any such Equity Securities are exercisable by their terms at such time) would exceed the total
number of shares of Common Stock then authorized by its certificate of incorporation.

(xii)
Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to the taking of any action which would require
an adjustment pursuant to this Section 11, the Company shall promptly take any and all action which may be necessary, including
obtaining regulatory or other governmental, The NASDAQ Global Select Market, or other applicable securities exchange, corporate, or shareholder
approvals or exemptions, in order that the Company may thereafter validly and legally issue as fully paid and nonassessable all shares
of Common Stock, or all other securities or other property, that the Warrantholder is entitled to receive upon exercise of this Warrant
pursuant to this Section 11.

(xiii)
No Adjustment for Permitted Transactions. Notwithstanding anything in this Warrant to the contrary, no adjustment shall
be made pursuant to this Section 11 in connection with any Permitted Transaction.

12.
Beneficial Ownership Limitation.

(i)
Notwithstanding anything in this Warrant to the contrary, the Company shall not honor any exercise of this Warrant, and a Warrantholder
shall not have the right to exercise any portion of this Warrant, to the extent that, after giving effect to an attempted exercise set
forth on an applicable Notice of Exercise, such Warrantholder (together with such Warrantholder’s Affiliates, and any other Person
whose beneficial ownership of Common Stock would be aggregated with the Warrantholder’s for purposes of Section 13(d) or
Section 16 of the Exchange Act, and any other applicable regulations of the Commission, including any Group of which the Warrantholder
is a member (the foregoing, “Attribution Parties”)) would beneficially own a number of shares of Common Stock in excess
of the Beneficial Ownership Limitation. For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned
by such Warrantholder and its Attribution Parties shall include the number of Warrant Shares issuable under the Notice of Exercise with
respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (a)
exercise of the remaining, unexercised portion of any Warrant beneficially owned by such Warrantholder or any of its Attribution Parties,
and (b) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company (including any warrants)
beneficially owned by such Warrantholder or any of its Attribution Parties that are subject to a limitation on conversion or exercise
similar to the limitation contained herein. For purposes of this Section 13, beneficial ownership shall be calculated in accordance
with Section 13(d) of the Exchange Act and any other applicable regulations of the Commission. For purposes of this Section
13
, in determining the number of outstanding shares of Common Stock, a Warrantholder may rely on the number of outstanding shares
of Common Stock as stated in the most recent of the following: (X) the Company’s most recent periodic or annual filing with the
Commission, as the case may be, (Y) a more recent public announcement by the Company that is filed with the Commission, or (Z) a more
recent notice by the Company or the Company’s transfer agent to the Warrantholder setting forth the number of shares of Common Stock
then outstanding. Upon the written request of a Warrantholder, the Company shall, within three Trading Days thereof, confirm in writing
to such Warrantholder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock
shall be determined after giving effect to any actual conversion or exercise of securities of the Company, including exercise of this
Warrant, by such Warrantholder or its Attribution Parties since the date as of which such number of outstanding shares of Common Stock
was last publicly reported or confirmed to the Warrantholder. The Company shall be entitled to rely on representations made to it by the
Warrantholder in any Notice of Exercise regarding its Beneficial Ownership Limitation. The Warrantholder acknowledges that the Warrantholder
is solely responsible for any schedules or statements required to be filed by it in accordance with Section 13(d) or Section 16(a)
of the Exchange Act.

15

been omitted pursuant to a request for confidential treatment and have been separately filed with the SEC.

(ii)
The “Beneficial Ownership Limitation” shall initially be 4.999% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of Warrant Shares pursuant to such Notice of Exercise (to the extent permitted
pursuant to this Section 12); provided, however, that by written notice to the Company, which will not be effective
until the 61st day after such notice is given by the Warrantholder to the Company, the Warrantholder may waive or amend the provisions
of this Section 12 to change the Beneficial Ownership Limitation to any other number, and the provisions of this Section 12
shall continue to apply. Upon any such waiver or amendment to the Beneficial Ownership Limitation, the Beneficial Ownership Limitation
may not be further waived or amended by the Warrantholder without first providing the minimum written notice required by the immediately
preceding sentence. Notwithstanding the foregoing, at any time following notice of an Acquisition Transaction under Section 11(v)
with respect to an Acquisition Transaction that is pursuant to any tender offer or exchange offer (by the Company or another Person (other
than the Warrantholder or any Affiliate of the Warrantholder)), the Warrantholder may waive or amend the Beneficial Ownership Limitation
effective immediately upon written notice to the Company and may reinstitute a Beneficial Ownership Limitation at any time thereafter
effective immediately upon written notice to the Company.

(iii)
Notwithstanding the provisions of this Section 12, none of the provisions of this Section 12 shall restrict in any
way the number of shares of Common Stock which the Warrantholder may receive or beneficially own in order to determine the amount of securities
or other consideration that the Warrantholder may receive in the event of an Acquisition Transaction as contemplated in Section 11
of this Warrant.

13.
Governing Law and Jurisdiction. This Warrant shall be governed by, and construed and enforced in accordance with, the
laws of the State of Delaware, without regard to any choice or conflict of law provision or rule (whether of the State of Delaware or

to deny or defeat such personal jurisdiction by motion or other request for leave from any such court and waives any claim of lack of
personal jurisdiction, improper venue and any claims that such courts are an inconvenient forum, and (c) agrees that it shall not bring
any claim, action, or proceeding relating to this Warrant or the transactions contemplated hereby in any court other than the Chosen Courts,
and in stipulated preference ranking, of the preceding clause (a). Each party agrees that service of process upon such party in any such

Specific Performance. The parties agree that failure of any party to perform its agreements and covenants under this Warrant,
including a party’s failure to take all actions as are necessary on such party’s part in accordance with the terms and conditions

aggregate Exercise Price if and when this Warrant is exercised in part or in whole.

this Warrant, they shall be deemed followed by the words “without limitation.” No rule of construction against the draftsperson
shall be applied in connection with the interpretation or enforcement of this Warrant, as this Warrant is the product of negotiation between
sophisticated parties advised by counsel. Any reference to a wholly owned subsidiary of a person shall mean such subsidiary is directly
or indirectly wholly owned by such person. All references to “$” or “dollars” mean the lawful currency of the
United States of America. Except as expressly stated in this Warrant, all references to any statute, rule, or regulation are to the statute,
rule or regulation as amended, modified, supplemented, or replaced from time to time (and, in the case of statutes, include any rules

Article
II

REPRESENTATIONS AND WARRANTIES

2.1            Material
Adverse Effect; Non-Reliance
.“Material Adverse Effect” means any
change, effect, event, development, circumstance, or occurrence (each, an “Effect”) that, taken individually or
when taken together with all other applicable Effects, has been, is, or would reasonably be, expected to be materially adverse to
(i) the business, assets, condition (financial or otherwise), or results of operations of the Company and its subsidiaries, taken as
a whole, or (ii) the ability of the Company to complete the transactions contemplated by the Transaction Documents or to perform its
obligations under the Transaction Documents; provided, however, that in no event shall any Effect, alone or in
combination, be deemed to constitute, or be taken into account in determining whether there has been, is, or would be, a Material
Adverse Effect to the extent resulting from: (A) any change in general economic, market, or political conditions; (B) any change in
generally accepted accounting principles in the United States (“GAAP”) or Applicable Law to the extent such
change is generally applicable and not specifically directed at the Company or its subsidiaries; (C) any act of war (whether or not
declared), armed hostilities, sabotage, or terrorism, or any material escalation or worsening of any such events, or any national
disaster or any national or international calamity; (D) any epidemic or pandemic, including COVID-19 or anything reasonably arising
therefrom, including without limitation the values of share prices traded on any stock market or exchange; (E) conditions generally
affecting the industries in which the Company operates; (F) any failure, in and of itself, to meet internal or published
projections, forecasts, targets, or revenue or earnings predictions for any period, as well as any change, in and of itself, by the
Company in any projections, forecasts, targets, or revenue or earnings predictions for any period (provided that the
underlying causes of such failures (to the extent not otherwise falling within one of the other exceptions in this proviso) may
constitute or be taken into account in determining whether there has been, is, or would be, a Material Adverse Effect); or (G) any
change in the price or trading volume of the Common Stock (provided that the underlying causes of such change (to the extent
not otherwise falling within one of the other exceptions in this proviso) may constitute or be taken into account in determining
whether there has been, is, or would be, a Material Adverse Effect); provided, further, that any Effect referred to in
clauses (A) through (E) may be taken into account in determining whether or not there has been, is, or would be, a Material Adverse
Effect if such Effect has a materially disproportionate adverse effect on the Company and its subsidiaries, taken as a whole, as
compared to other similarly situated participants in the industry in which the Company and its subsidiaries operate.

2

(b)
Each party acknowledges that it is not relying upon any representation or warranty of the other party, express or implied,
not set forth in the Transaction Documents. Amazon acknowledges that it has had an opportunity to conduct such review and analysis of
the business, assets, condition, operations, and prospects of the Company and its subsidiaries, including an opportunity to ask such questions
of management and to review such information maintained by the Company and its subsidiaries, in each case as it considers sufficient for
the purpose of consummating the transactions contemplated by the Transaction Documents. Each party further acknowledges that it has had
such an opportunity to consult with its own counsel, financial and tax advisers, and other professional advisers as it believes is sufficient
for purposes of the transactions contemplated by the other Transaction Documents.

2.2
Representations and Warranties of the Company. Except as set forth in the correspondingly numbered section of the
Disclosure Schedules or any disclosure in the SEC Reports (other than any information in the “Risk Factors” or “Forward-Looking
Statements” sections of such SEC Reports), the Company represents and warrants as of the date of this Agreement, and in the case
of the representation in the last sentence of Section 2.2(c), as of the date of each issuance of Warrant Shares, to Amazon that:

(a)              Organization
and Authority
. The Company (i) has been duly incorporated and is validly existing as a corporation in good standing under the
laws of the State of Delaware, with full corporate power and authority to own its properties and conduct its business in all
material respects as currently conducted, and except as would not constitute a Material Adverse Effect, has been and is duly
qualified as a foreign corporation for the transaction of business and is in good standing under the laws of each other jurisdiction
in which the ownership or leasing of property or the conduct of its business requires such qualification. The Company has made
available to Amazon complete and correct copies of the Company’s certificate of incorporation and bylaws, as of the date of
this Agreement, and each as so delivered is in full force and effect.

3

(b)
Capitalization. The authorized capital stock of the Company consists of 304,000,000 shares of Common Stock of which,
immediately prior to the execution hereof, 199,835,902 shares were issued and outstanding and no shares were held in treasury, and 1,000,000
shares of preferred stock, $0.0001 par value per share of which, immediately prior to the execution hereof, no shares were issued and
outstanding. The Company has (i) 9,653,018 shares of Common Stock subject to issuance pursuant to outstanding stock options of the Company,
(ii) 1,243,946 shares of Common Stock subject to issuance pursuant to service-based restricted stock units, (iii) 1,847,440 shares of
Common Stock available for future issuance under the Company’s employee stock purchase plan, and (iv) no shares of Common Stock
subject to issuance pursuant to outstanding warrants of the Company. The outstanding shares of Common Stock have been, and the shares
of Common Stock issuable pursuant to any Company Stock Plan will be, duly authorized and validly issued, fully paid, and nonassessable,
and subject to no preemptive rights (and were not issued in violation of any preemptive rights, the Company’s certificate of incorporation,
or any Applicable Law). Except as set forth above or pursuant to the Warrant, there are no (A) shares of capital stock or other Equity
Securities or voting securities of the Company authorized, reserved for issuance, issued, or outstanding, (B) options, warrants, calls,
preemptive rights, subscription, or other rights, instruments, agreements, arrangements, or commitments of any character, obligating the
Company or any of its subsidiaries to issue, transfer, or sell or cause to be issued, transferred, or sold any shares of capital stock
or other Equity Securities or voting security in the Company or any securities or instruments convertible into or exchangeable for such
shares of capital stock or other Equity Securities or voting securities, or obligating the Company or any of its subsidiaries to grant,
extend, or enter into any such option, warrant, call, preemptive right, subscription, or other right, instrument, agreement, arrangement,
or commitment, (C) outstanding contractual obligations of the Company or any of its subsidiaries to repurchase, redeem, or otherwise acquire
any capital stock or other Equity Securities or voting securities of the Company, excluding for the purposes hereof, any purchases of
Equity Securities of the Company or any Affiliate pursuant to the $30 million share repurchase program in existence as of the date hereof
approved by the Company’s Board of Directors on March 12, 2020 pursuant to and in compliance with the requirements of Rule 10b-18
under the Exchange Act and any purchases of shares of Common Stock in connection with the net exercise of options, or the payment of tax
withholding with respect to equity incentive awards, issued under the Company’s equity incentive plans, or (D) issued or outstanding
performance awards, units, rights to receive any capital stock, or other Equity Securities or voting securities of the Company on a deferred
basis, or rights to purchase or receive any capital stock or Equity Securities or voting securities issued or granted by the Company to
any current or former director, officer, employee, or consultant of the Company. No subsidiary of the Company owns any shares of capital
stock or other Equity Securities or voting securities of the Company. There are no voting trusts or other agreements or understandings
to which the Company or any of its subsidiaries is a party with respect to the voting of the capital stock or other Equity Securities
or voting securities of the Company. All options granted and shares reserved or issued pursuant to the Company’s 2002 Stock Option
Plan, 2006 Equity Incentive Plan, Amended and Restated 2016 Performance Incentive Plan, and employee stock purchase plan (collectively,
the “Company Stock Plans”) have been granted, reserved, and issued in all material respects in full compliance with
their respective Company Stock Plan and Applicable Law. The issuance of the Warrant and the Warrant Shares will not result in any adjustment
to the conversion price or exercise price of any securities of the Company that are convertible into, or exercisable or exchangeable for,
shares of Common Stock. As of immediately prior to the execution hereof, assuming the issuance of the Warrant Shares in full, the number
of Warrant Shares equals 19.999% of the outstanding shares of Common Stock on a fully diluted basis.

4

(c)
The Warrant and Warrant Shares. The Warrant has been duly authorized by the Company and constitutes a valid, legal,
and binding obligation of the Company in accordance with its terms, except as the same may be limited by the Bankruptcy Exceptions. The
Warrant Shares have been duly authorized and reserved for issuance upon exercise of the Warrant, and when so issued, paid for, and delivered
upon due exercise of the Warrant, will be validly issued, fully paid and nonassessable, and free and clear of any liens or encumbrances,
other than liens or encumbrances created by the Transaction Documents, arising as a matter of Applicable Law or created by or at the direction
of Amazon or any of its subsidiaries.

(d)

(i)
The Company has full power and authority to execute and deliver this Agreement and the other Transaction Documents, as applicable,
to consummate the transactions contemplated hereby and thereby, and to carry out its obligations hereunder and thereunder (except with
respect to the issuance of Warrant Shares in an amount in excess of 50,595,531, for which the sole action necessary to make this representation
true is to obtain the Requisite Stockholder Approval). The execution, delivery, and performance by the Company of this Agreement and the
other Transaction Documents to which it is a party and the consummation of the transactions contemplated hereby and thereby have been
duly authorized by all necessary corporate action on the part of the Company and its stockholders, and no further approval or authorization
is required on the part of the Company or its stockholders. This Agreement and the other Transaction Documents, assuming the due authorization,
execution, and delivery by the other parties hereto and thereto, are valid and binding obligations of the Company, enforceable against
the Company and such subsidiary, respectively, in accordance with their respective terms, except as the same may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, or similar laws affecting the enforcement of creditors’ rights generally and
general equitable principles, regardless of whether such enforceability is considered in a proceeding at law or in equity (“Bankruptcy
Exceptions
”).

(ii)              The
execution, delivery and performance by the Company of this Agreement and the other Transaction Documents, as applicable, and the
consummation of the transactions contemplated hereby and thereby and compliance by the Company with any of the provisions hereof and
thereof, will not (A) violate, conflict with, or result in a breach of any provision of, or constitute a default (or an event which,
with notice or lapse of time or both, would constitute a default) under, or result in the termination of, or accelerate the
performance required by, or result in a right of termination or acceleration of, or result in the creation of, any lien, security
interest, charge, or encumbrance upon any of the properties or material assets of the Company or any of its subsidiaries under any
of the terms, conditions, or provisions of (x) its certificate of incorporation (or analogous organizational documents) or (y) any
note, bond, mortgage, indenture, deed of trust, license, lease, agreement, or other instrument or obligation to which the Company or
any of its subsidiaries is a party or by which it or any of its subsidiaries may be bound, or to which the Company or any of its
subsidiaries or any of the properties or assets of the Company or any of its subsidiaries is subject; (B) subject to compliance with
the statutes and regulations referred to in the next paragraph, violate any Applicable Law or Order applicable to the Company or any
of its subsidiaries or any of their respective properties or assets except, in the case of clauses (A)(y) and (B), for those
occurrences that would not constitute a Material Adverse Effect; (C) result in any payment (including severance, unemployment
compensation, forgiveness of indebtedness, or otherwise) becoming due to any director or any employee of the Company or any of its
subsidiaries under any employment, compensation or benefit plan, program, policy, agreement, or arrangement that is sponsored,
maintained, or contributed to by the Company or any of its subsidiaries (each, a “Company Benefit Plan”) or
otherwise; (D) increase any benefits otherwise payable under any Company Benefit Plan; (E) result in any acceleration of the time of
payment or vesting of any such benefits; (F) require the funding or acceleration of funding of any trust or other funding vehicle;
or (G) constitute a “change in control,” “change of control,” or other similar term under any Company
Benefit Plan; provided, however, that the foregoing shall not be deemed to include payments or other benefits under a
Company Benefit Plan that (a) gives effect to the Company’s performance of the Transaction Documents insofar as that
performance impacts the Company’s overall results of operations, and (b) are made to any individual whose compensation is
based in part on performance related to a specific territory that is impacted by the Company’s performance of the Transaction
Documents.

(iii)
Other than (A) such notices, filings, exemptions, reviews, authorizations, consents, or approvals as have been made or obtained
as of the date hereof, and (B) notices, filings, exemptions, reviews, authorizations, consents, or approvals as may be required under,
and other applicable requirements of (1) any Antitrust Laws, to the extent applicable, (2) the Exchange Act, (3) the Securities Act, and
(4) The NASDAQ Global Select Market, no notice to, filing with, exemption, or review by, or authorization, consent, or approval of, any
Governmental Entity is required to be made or obtained by the Company or any of its subsidiaries in connection with the consummation by
the Company or any of its subsidiaries of the Warrant Issuance and the other transactions contemplated hereby and by the other Transaction

Article
III

COVENANTS

3.1
Efforts.

(a)               Without
prejudice to the terms and conditions hereof (including the remainder of this Section 3.1) and the other Transaction
Documents, each party shall use its commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause
to be done, all things necessary, proper, or desirable under Applicable Law to carry out the provisions hereof and thereof and give
effect to the transactions contemplated hereby and thereby. In furtherance and not in limitation of the foregoing, each of the
parties shall (i) subject to the provisions of this Section 3.1, including Section 3.1(d), use its commercially
reasonable efforts to obtain as promptly as reasonably practicable and advisable (as determined in good faith by Amazon after
consultation with the Company in accordance with the first sentence of Section 3.1(d)) all exemptions, authorizations,
consents, or approvals from, and to make all filings with and to give all notices to, all third parties, including any Governmental
Entities, required in connection with the transactions contemplated by this Agreement and the other Transaction Documents (including
as may be required upon one or more exercises of Warrant Shares, and whether such approvals arise from Antitrust Laws or otherwise,
or one or more sales of Warrant Shares), which, for the avoidance of doubt, shall include providing, as promptly as reasonably
practicable and advisable, such information to any Governmental Entity as such Governmental Entity may request in connection
therewith, and (ii) cooperate fully with the other party in promptly seeking to obtain all such exemptions, authorizations,
consents, or approvals and to make all such filings and give such notices.

11

(b)
Without limiting the generality of the foregoing, as promptly as practicable after written notice from Amazon, and in any
event no later than in accordance with established regulatory time frames, the parties shall (i) file any Notification and Report Forms
required or advisable under the HSR Act with the Federal Trade Commission and the United States Department of Justice and (ii) file, make
or give, as applicable, all other filings, requests or notices required or advisable under any other Antitrust Laws, in each case with
respect to the issuance of the Warrant Shares (the “Initial Filing Transaction”) (the filings, requests and notices
described in the foregoing clauses (i) and (ii), collectively, the “Initial Antitrust Filings”). In addition, following
the receipt of the Initial Antitrust Clearance, to the extent required or advisable by Applicable Law (including, for the avoidance of
doubt, any Antitrust Law) in connection with any further issuance of Warrant Shares (in each case, whether in full or in part), the parties
shall file, make, or give, as applicable, as promptly as reasonably practicable and advisable (as determined in good faith by Amazon after
consultation with the Company in accordance with the first sentence of Section 3.1(d)), any further filings, requests or notices
required under any Antitrust Laws, including the HSR Act. Without limiting the generality of the foregoing, each party shall supply as
promptly as reasonably practicable to the appropriate Governmental Entities, and in any event no later than in accordance with established
regulatory time frames, any information and documentary material that may be required pursuant to the HSR Act or any other Antitrust Laws.
For purposes of this Agreement, the term “Initial Antitrust Clearance” as of any time means (x) prior to such time,
the expiration or termination of the waiting period under the HSR Act and the receipt of all exemptions, authorizations, consents, or
approvals, the making of all filings and the giving of all notices, and the expiration of all waiting periods, pursuant to any other Antitrust
Laws, in each case to the extent required with respect to the Initial Filing Transaction, and (y) the absence at such time of any Applicable
Law or Order issued by any court of competent jurisdiction or other legal restraint or prohibition under any Antitrust Law, in each case
that has the effect of preventing the consummation of any issuances of Warrant Shares.

(c)              Subject
to the terms and conditions hereof (including the remainder of this Section 3.1) and the other Transaction Documents, and
only to the extent required under the Antitrust Laws, each of the parties shall use its commercially reasonable efforts to avoid or
eliminate each and every impediment under any Antitrust Laws that may be asserted by any Governmental Entity, so as to enable the
parties to give effect to the transactions contemplated hereby and by the other Transaction Documents in accordance with the terms
hereof and thereof; provided, that notwithstanding anything to the contrary contained herein or in any of the other
Transaction Documents, nothing in this Section 3.1 shall require, or be construed to require, any party or any of its
Affiliates to agree to (and no party or any of its Affiliates shall agree to, without the prior written consent of the other
parties): (i) sell, hold separate, divest, discontinue, or limit (or accept any conditions relating to, or changes or restrictions
in, the operation of) any assets, businesses, or interests of it or its Affiliates (irrespective of whether or not such assets,
businesses, or interests are related to, are the subject matter of, or could be affected by the transactions contemplated by the
Transaction Documents); (ii) without limiting clause (i) in any respect, accept any conditions relating to, or changes or
restrictions in, the operations of any such assets, businesses, or interests that would reasonably be expected to adversely impact
(x) the business of, or the financial, business, or strategic benefits of the transactions contemplated hereby or by any of the
other Transaction Documents to it or its Affiliates, or (y) any other assets, businesses, or interests of it or its Affiliates;
(iii) without limiting clause (i) in any respect, accept any modification or waiver of the terms and conditions of this Agreement or
any of the other Transaction Documents that would reasonably be expected to adversely impact (x) the business of, or financial,
business, or strategic benefits of the transactions contemplated hereby or by any of the other Transaction Documents to it or its
Affiliates, or (y) any other assets, businesses, or interests of it or its Affiliates; or (iv) without limiting clause (i) in any
respect, take any action that would materially impair the value to Amazon of the transactions contemplated hereby.

12

(d)
Amazon shall have the principal responsibility for devising and implementing the strategy (including with respect to the
timing of filings) for obtaining any exemptions, authorizations, consents, or approvals required or advisable under the HSR Act or any
other Antitrust Laws in connection with the transactions contemplated hereby and by the other Transaction Documents; provided,
however, that Amazon shall consult in advance with the Company regarding the overall antitrust strategy. Each of the parties shall
promptly notify the other party of, and if in writing furnish the other with copies of (or, in the case of oral communications, advise
the other of), any substantive communication that it or any of its Affiliates receives from any Governmental Entity, whether written or
oral, relating to the matters that are the subject of this Agreement or any of the other Transaction Documents, and to the extent reasonably
practicable, permit the other party to review in advance any proposed substantive written communication by such party to any Governmental
Entity and consider in good faith the other party’s reasonable comments on any such proposed substantive written communications
prior to their submission. No party shall, and each party shall cause its Affiliates not to, participate or agree to participate in any
substantive meeting or communication with any Governmental Entity in respect of the subject matter of the Transaction Documents, including
on a “no names” or hypothetical basis, unless (to the extent practicable) it or they consult with the other party in advance,
and to the extent practicable and permitted by such Governmental Entity, give the other party the opportunity to jointly prepare for,
attend, and participate in such meeting or communication. The parties shall (and shall cause their subsidiaries and Representatives to)
to the extent not prohibited by Applicable Law coordinate and cooperate fully with each other in exchanging such information and providing
such assistance as the other party may reasonably request in connection with the matters described in this Section 3.1, including
(x) furnishing to each other all information reasonably requested to determine the jurisdictions in which a filing or submission under
any Antitrust Law is required or advisable, (y) furnishing to each other all information required for any filing or submission under any
Antitrust Law, and (z) keeping each other reasonably informed with respect to the status of each exemption, authorization, consent, approval,
filing, and notice under any Antitrust Law, in each case, in connection with the matters that are the subject of this Agreement or any
of the other Transaction Documents. The parties shall provide each other with copies of all substantive correspondence, filings, or communications
between them or any of their Affiliates or Representatives, on the one hand, and any Governmental Entity or members of its staff, on the
other hand, relating to the matters that are the subject of this Agreement or any of the other Transaction Documents; provided that
such material may be redacted as necessary to (1) comply with contractual arrangements, (2) address good faith legal privilege or confidentiality
concerns, and (3) comply with Applicable Law.

13

(e)
Subject to the other provisions of this Agreement, including in this Section 3.1, in the event that any arbitral,
administrative, judicial, or analogous action, claim, or proceeding is instituted (or threatened to be instituted) by a Governmental Entity
or any other party relating to or in connection with the transactions contemplated hereby or by any of the other Transaction Documents
(“Transaction Litigation”), neither party shall be required to contest and resist any such Transaction Litigation or
to seek to have vacated, lifted, reversed, or overturned any judgment, ruling, order, writ, injunction, or decree, whether temporary,
preliminary, or permanent, that is in effect and that prohibits, prevents, or restricts consummation or implementation of the transactions
contemplated hereby or by any of the other Transaction Documents. Each party shall keep the other party reasonably informed with respect
to any Transaction Litigation unless doing so would reasonably be likely to jeopardize any privilege of such party regarding any such
Transaction Litigation (subject to such party using commercially reasonable efforts to develop and implement, and cooperating in good
faith with the other party in developing and implementing, reasonable alternative arrangements to provide such other party with such information).
Subject to the immediately preceding sentence, each party shall promptly advise the other party orally and in writing in connection with,
and shall consult with each other with respect to, any Transaction Litigation and shall in good faith give consideration to each other’s
advice with respect to such Transaction Litigation.

(f)
The Company shall be liable for and promptly indemnify Amazon for all Losses incurred by Amazon or its Affiliates that arise
out of or relate to any Transaction Litigation.

(g)
As promptly as practicable following the date hereof, the Company shall adopt such amendments and take such further actions
and do or cause to be done all things necessary, proper, or advisable under Applicable Law to prevent the execution and delivery of the
Transaction Documents and the consummation of the transactions contemplated thereby from constituting a “change in control,”
“change of control,” or other similar term under any Company Benefit Plan.

(h)
Notwithstanding anything herein to the contrary, from and after the earlier of (i) the exercise of the Warrant in full and
(ii) the expiration, termination, or cancellation of the Warrant without the Warrant having been exercised in full, no party shall have
any further obligations under this Section 3.1; provided, that this Section 3.1(h) shall in no way relieve any party
with respect to any breach by such party of this Section 3.1 prior to such time.

14

3.2
Public Announcements.

(a)              The
parties acknowledge that the Company’s initial announcement of the transactions contemplated by this Agreement and the other
Transaction Documents to customers, suppliers, investors, employees, and otherwise (the “Initial Announcement”)
and the timing thereof has been agreed by the parties. Other than the transmission of the Initial Announcement at the time mutually
agreed upon by the parties, except as required by Applicable Law or by the rules or requirements of any stock exchange on which the
securities of a party are listed, no party shall make, or cause to be made, or permit any of its Affiliates to make, any press
release or public announcement or other similar communications in respect of the Transaction Documents or the transactions
contemplated thereby without prior written consent (not to be unreasonably withheld, conditioned, or delayed) of the other party, to
the extent such release, announcement, or communication relates to the transactions contemplated hereby or by any of the other
Transaction Documents. Notwithstanding the foregoing, no party shall be required to receive the consent of the other party to any
release, announcement, or communication (including any filing required to be made under the Exchange Act or the Securities Act) to
the extent such release, announcement, or communication includes information (i) with respect to the transactions contemplated
hereby or by any of the other Transaction Documents that is consistent with the Initial Announcement, provided that such
release, announcement, or communication follows the Initial Announcement; (ii) that is consistent with releases, announcements, or
other communications previously consented to by the other party in accordance with this Section 3.2; (iii) that is required
to be disclosed under GAAP; (iv) that has previously been released by either of the parties hereto in respect of the transactions
contemplated hereby or the Transaction Documents without any violation of the terms of this Agreement; or (v) as may be required in
connection with any Form 4, Schedule 13D, Schedule 13G, Form 8-K, Form 10-Q, Form 10-K, Schedule 14A, or other disclosure required
by the Commission or other Governmental Entity to be made by Amazon or the Company in connection with the transactions contemplated
by the Transaction Documents. Notwithstanding the preceding sentence, to the extent any disclosure (including communications with
investors and analysts) relates to the Transaction Documents or any transaction contemplated thereby and contains any information
inconsistent with the Initial Announcement or releases, announcements or other communications previously consented to by the other
party in accordance with this Section 3.2 or that has previously been released by either of the parties hereto in respect of
the transactions contemplated hereby or the Transaction Documents without any violation of the terms of this Agreement, such
disclosure shall be subject to the prior consent of the other party (unless it is required to be in such form under Applicable Law),
which shall not be unreasonably withheld, conditioned, or delayed.

15

(b)              Without
limiting the foregoing, in recognition of the importance to the Company and Amazon of taking appropriate steps to maintain the
confidentiality of agreements between the parties from the parties’ customers, competitors, and suppliers, in the event that
the Company is requested by the Commission or any other regulatory body or stock exchange (the Commission and each such other
regulatory body or stock exchange, a “Disclosure Agency”), or legally required to file or otherwise submit any
agreement to which Amazon is a party (each a “Disclosable Agreement”) or any excerpt from, summary of, or
information relating to any Disclosable Agreement with or to a Disclosure Agency the filing or submission of which involves or could
result in public disclosure of such Disclosable Agreement or excerpt therefrom, summary thereof, or information relating thereto,
the Company will (1) promptly notify Amazon of such request or requirement to file or otherwise submit the Disclosable Agreement or
any excerpt therefrom, summary thereof, or information relating thereto and any applicable deadline for making such filing or
submission, (2) use reasonable efforts to persuade the Disclosure Agency that the Company is not required to file or otherwise
submit the Disclosable Agreement pursuant to Applicable Laws, and to the extent such efforts are not successful, (3) provide Amazon
with a reasonable opportunity to request (i) a redaction to the extent reasonably permitted by Applicable Law of any information in
the Disclosable Agreement or excerpt therefrom, summary thereof, or information relating thereto (in addition to any redactions
proposed by the Company) prior to filing or submitting such Disclosable Agreement, excerpt therefrom, summary thereof, or
information relating thereto, and (ii) if requested or required by the Disclosure Agency, the submission of a confidential treatment
request in support of such redactions with such arguments as requested by Amazon, including in response to any comments or requests
for information issued by the applicable Disclosure Agency, to which, in each case, the Company shall agree absent a reasonable
basis for objection (and shall provide Amazon prompt notice of any such objection, the basis therefor and a reasonable opportunity
to consider and discuss such objection with the Company), (4) provide Amazon (i) with copies of any comments and all other
communications received from the applicable Disclosure Agency with respect to the Disclosable Agreement or confidential treatment
thereof (including a reasonable summary of any oral communications or other comments received other than in writing) as promptly as
reasonably practicable and (ii) with the Company’s proposed response to such comments at least three Business Days before such
response is submitted to the applicable Disclosure Agency, and (5) provide Amazon with a reasonable opportunity to propose revisions
within such time period to such proposed response as requested by Amazon, and which revisions the Company shall make absent a
reasonable basis for objection (and shall provide Amazon prompt notice of any such objection, the basis therefor and a reasonable
opportunity to consider and discuss such objection with the Company), and as applicable, use its commercially reasonable efforts in
responding to any such comments in order to pursue assurance that confidential treatment will be granted. The Company will not file
this Agreement, any Disclosable Agreement, any excerpt therefrom, summary or portion thereof, or information relating thereto with
any Governmental Entity or regulatory body, including any Disclosure Agency, or disclose any other confidential and/or commercially
sensitive information in any manner, except to the extent (i) permitted above, or (ii) the Company determines in good faith based on
the advice of outside counsel that making such filing or submission without adhering to the requirements set forth above is
necessary to comply with Applicable Law. Notwithstanding anything in Section 8.1 of this Agreement to the contrary, the
provisions of this Section 3.2(b) will survive for so long as any Commercial Arrangements remain in effect.

3.3
Expenses. Unless otherwise provided in any Transaction Document, each of the parties shall bear and pay all costs
and expenses incurred by it or on its behalf in connection with the transactions contemplated under the Transaction Documents, including
fees and expenses of its own financial or other consultants, investment bankers, accountants, and counsel.

Proxy Statement.

(i)
As promptly as practicable after the date hereof, the Company shall prepare and file with the Commission a proxy statement
relating to the issuance of Warrant in respect of any Warrant Shares in excess of 50,595,531 shares of Common Stock (for the avoidance
of doubt, without giving effect to any “cashless” or “net” exercise provisions therein and with giving effect
to any adjustments set forth in Section 11 of the Warrant) for the purpose of complying with Nasdaq Listing Rule 5635(b) (the “Company
Stockholder Matters
” and such proxy statement together with any amendments thereof or supplements thereto, the “Proxy

provide Amazon with no less than two full Business Days to comment thereon, and which revisions the Company shall make absent a reasonable
basis for objection (and shall provide Amazon prompt notice of any such objection, the basis therefor and a reasonable opportunity to
consider and discuss such objection with the Company). The Company shall notify Amazon within one Business Day of the receipt of any comments
from the Commission or its staff with respect to the Proxy Statement and of any request by the Commission or its staff for amendments
or supplements to such Proxy Statement or for additional information and shall supply Amazon with copies of all correspondence between
the Company or any of its Representatives, on the one hand, and the Commission or its staff, on the other hand, with respect to such Proxy
Statement. The Company shall (A) cause the Proxy Statement to comply with the applicable rules and regulations promulgated by the Commission
and (B) respond promptly to any comments or requests of the Commission or its staff relating to the Proxy Statement.

(ii)
The Company covenants and agrees that the Proxy Statement (and the letter to stockholders, notice of meeting and form of
proxy included therewith) will (A) comply as to form in all material respects with the requirements of Applicable Law, and (B) not contain
any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make
the statements made therein, in light of the circumstances under which they were made, not misleading.

(iii)
The Company will file the definitive Proxy Statement within 1 Business Day after either (A) the Commission has indicated
that it does not intend to review the Proxy Statement or that its review of the Proxy Statement has been completed or (B) at least ten
calendar days shall have passed since the Proxy Statement was filed with the Commission without receiving any correspondence from the
Commission commenting upon, or indicating that it intends to review, the Proxy Statement, all in compliance with Applicable Law. The Company
shall commence mailing of the Proxy Statement to the Company’s stockholders within 2 Business Days after the definitive Proxy Statement
has been filed with the Commission. If the Company becomes aware of any event or information that, pursuant to Applicable Laws, should
be disclosed in an amendment or supplement to the Proxy Statement, as the case may be, then the Company shall promptly as reasonably practicable
file such amendment or supplement with the Commission and, if appropriate, mail such amendment or supplement to the Company Stockholders.

(b)              Stockholder’s
Meeting
. The Company shall take all action necessary under Applicable Law to call, give notice of and hold a meeting of the
holders of Common Stock (the “Company Stockholders”) to consider and vote to approve the Company Stockholder
Matters pursuant to the terms of this Agreement (such meeting, the “Company Stockholder Meeting” and such
approval, the “Requisite Stockholder Approval”). The Company Stockholder Meeting shall be held as promptly as
practicable after the date that the definitive Proxy Statement is filed with the Commission, and in any event no later than 45 days
after such date. The Company shall take reasonable measures to ensure that all proxies solicited in connection with the Company
Stockholder Meeting are solicited in compliance with Applicable Law. The Company shall regularly provide updates to Amazon on voting
totals with respect to the Company Stockholder Matters. The Company Stockholder Meeting will be postponed or adjourned in accordance
with the Company’s bylaws or as otherwise required by Applicable Law if the Company determines that in good faith (after
reasonable consultation with Amazon) (w) it is probable that the proposals regarding the Company Stockholder Matters will not pass,
(x) there is an insufficient number of shares of Common Stock present or represented by a proxy at the Company Stockholder Meeting
to conduct business at the Company Stockholder Meeting, (y) the Company is required to postpone or adjourn the Company Stockholder
Meeting by Applicable Law or a request from the Commission or its staff, or (z) it is necessary or appropriate to postpone or
adjourn the Company Stockholder Meeting in order to give the Company Stockholders sufficient time to evaluate any supplemental
information or disclosure that the Company has sent or otherwise made available to them; provided, however, the date
of the Company Stockholder Meeting may not be postponed or adjourned more than an aggregate of 30 days in connection with any
postponement or adjournment. If the Requisite Stockholder Approval is not obtained at or prior to the Company Stockholder Meeting,
the Company shall at Amazon’s request cause an additional Company Stockholder Meeting to be held every 12 months thereafter
until the earlier of the time such Requisite Stockholder Approval is obtained or the Expiration Time.

(c)
Board Recommendation. The Company shall use its commercially reasonable efforts to obtain the Requisite Stockholder
Approval. Without limiting the foregoing, the Board shall (x) recommend that the Company Stockholders vote in favor of the Requisite Stockholder
Approval (the “Company Board Recommendation”) and not withdraw or modify in any adverse respect such Company Board
Recommendation unless the Board determines in good faith (after determining in good faith based on the written advice of outside legal
counsel and financial advisors) that the failure to take such action would be inconsistent with its fiduciary duties to the holders of
Common Stock under Applicable Law, (y) solicit proxies in favor of the Requisite Stockholder Approval in accordance with this Section
3.4
, and (z) the Proxy Statement shall include a statement to the effect that the Board
recommends that the Company Stockholders vote to approve the Company Stockholder Matters. If the Board withdraws, changes, or qualifies
in any manner adverse to Amazon, the Company Board Recommendation or fails to include the Company Board Recommendation in the Proxy Statement
when disseminated to the Company Stockholders, Amazon shall have the right, at its option, to require the Company to negotiate in good
faith with Amazon to amend the terms of the Warrant and the other Transaction Documents in order to ensure that Amazon obtains all of
the benefits intended to be conferred in connection with this Agreement and the transactions contemplated hereby. The Company shall engage
MacKenzie Partners, Inc. to perform customary and reasonable solicitation efforts, solely at the Company’s expense, in order to
obtain the Requisite Stockholder Approval.

(d)
Cooperation. Amazon shall furnish the Company all information reasonably requested by the Company concerning itself,
its Affiliates, directors, officers, stockholders and such other matters as may be reasonably necessary or advisable in connection with
the Company Stockholder Matters set forth in the Proxy Statement.

(e)              Support
Agreements
. From and after the date of this Agreement until the date of the Requisite Stockholder Approval, the Company shall
use reasonable efforts to request all new beneficial owners of Common Stock in excess of five percent of the Common Stock
outstanding (each, a “Significant Stockholder”), within ten Business Days after such Person becoming a
Significant Stockholder, to deliver to the Company a voting agreement, if it has not already done so, in support of the Company
Stockholder Matters in substantially the form attached hereto as Annex B.

18

3.5
Tax Treatment. Amazon and the Company agree to treat the Warrant Issuance (i) as a closed, taxable transaction occurring
on the date of the Warrant Issuance, rather than as an open transaction, for U.S. tax purposes, and (ii) not as a transaction in connection
with the performance of services within the meaning of Section 83 of the Code. Amazon shall control the valuation of the Warrant for all
relevant U.S. federal, state and local tax purposes. Neither Amazon nor the Company shall take any position for tax purposes that is inconsistent
with the foregoing, unless required by a determination (within the meaning of Section 1313(a) of the Code).

transactions contemplated hereby or thereby, to be subject to any requirements imposed by any Anti-Takeover Provisions or subject in any

(although the representation and warranty in Section 2.3(a) shall be made with respect to the applicable jurisdiction of incorporation
and to the extent the concept is applicable in that jurisdiction) and Section 4.1.

a counterpart signature to such joinder agreement; and

(ii)              if
any Transferee has not either (A) entered into or is bound by a mutual nondisclosure agreement enforceable directly by the Company
on terms that are substantially similar as the Confidentiality Agreement or (B) agreed to be bound by the terms of the
Confidentiality Agreement to the same extent as if the Transferee were a party thereto, the Company shall not, notwithstanding any
provision of any Transaction Document to the contrary, be required to disclose any Confidential Information to such Transferee
unless and until such agreement has been entered into.

21

4.5

anything to the contrary contained herein or in any of the other Transaction Documents, including Section 4.5(a)
hereof, Amazon shall not be prohibited or restricted from making and submitting to the Company and/or the Board, any Acquisition
Proposal that is not intended to require the Company to disclose such proposal, or any confidential request for the Company and/or
the Board to waive, amend, or provide a release of any provision of this Section 4.5 (whether
or not in connection with such Acquisition Proposal); provided that any such Acquisition Proposal and/or confidential request shall
by its terms terminate if it is publicly disclosed or announced by Amazon (except in the event that such public disclosure is
required by Applicable Law) without the prior approval of the Board. If the Company (through the Board or otherwise) shall have
commenced a process to solicit Acquisition Proposals from third parties, then the Company will promptly notify Amazon of such
determination and any information provided to Amazon in connection with such notice, including, without limitation, the fact that
the Company has provided such notice to Amazon, shall be kept confidential by Amazon, except to the extent information is permitted
to be disclosed or used by Section ‎‎5.1(c).

(c)
Notwithstanding anything to the contrary herein, the provisions of this Section 4.5
shall become void and of no further force and effect upon (i) the public announcement by the Company that it has entered into a definitive
agreement with a Person other than Amazon or any of its subsidiaries for a transaction involving a Business Combination or (ii) if any
Person other than Amazon or any of its subsidiaries commences a tender or exchange offer which, if consummated, would constitute a Business
Combination; provided, however, that with respect to clauses (i) and (ii) of this sentence, Amazon shall not have materially
breached any of the provisions of this Section 4.5.

than five percent of the outstanding shares of Common Stock; provided, however, that if the Beneficial Ownership of Amazon

following such occurrence, then the provisions of this Section 4.5 shall automatically
and immediately again become applicable to Amazon.

4.6
Right of Notice. Subject to the confidentiality obligations set forth in the Confidentiality Agreement, if at any
time the Company proposes to enter into an exclusivity agreement or other agreement that contemplates exclusivity with any Person
or Group (excluding Amazon or any of its

the Company shall promptly, and in any event no later than ten Business Days prior to entering into
such agreement,
provide written notice to Amazon, which notice shall contain all terms of such proposed Acquisition Transaction as well as all information
or draft documentation which may impact Amazon in its capacity as a holder of the Warrant.

substantially similar to this Section 5.1(c)); or

(iv)
by Amazon or any of its Representatives to the extent that Amazon or such Representative has been advised by its outside
legal counsel that such disclosure is required to be made by it under Applicable Law or by a Governmental Entity; provided, that
prior to making such disclosure, such Person uses commercially reasonable efforts to preserve the confidentiality of the Confidential
Information to the extent permitted by Applicable Law, including, to the extent practicable and permitted by Applicable Law, consulting
with the Company regarding such disclosure, and if reasonably requested by the Company, assisting the Company, at the Company’s
expense, in seeking a protective order to prevent the requested disclosure; provided, further, that Amazon or such Representative,
as the case may be, uses commercially reasonable efforts to disclose only that portion of the Confidential Information as is requested
by the applicable Governmental Entity or as is, based on the advice of its outside legal counsel, legally required or compelled; and provided,
further, that the parties hereto expressly agree that notwithstanding anything in the Confidentiality Agreement or any other confidentiality
agreement between or among the Company, Amazon, or any of their respective subsidiaries or Representatives to the contrary, any Confidential
Information that is permitted to be disclosed in any manner pursuant to this Agreement can be so disclosed in the manner provided in this
Section 5.1(c)(iv).

the Company or any of its affiliates.

that Amazon is subject to the same reporting requirements, the Company shall file on Amazon’s behalf if permitted by
applicable law. The Company shall also provide Amazon with any such filings under such sections for Amazon’s review 45 days
prior to the due date for filing (including extensions). To the extent that the Company does not have a filing requirement under
such sections, the Company shall provide such information to Amazon as may be necessary to fulfill Amazon’s obligations
thereunder as a result of the Warrant Issuance or the acquisition of Warrant Shares hereunder.

REGISTRATION

6.1
Demand Registrations.

(a)
Subject to the terms and conditions hereof, solely during any period that the Company is then ineligible under Applicable
Law to register Registrable Securities on a registration statement on Form S-3, or if the Company is so eligible but has failed to comply
with its obligations under Section 6.3, any Demand Shareholder(s) (whether singular or plural, referred to herein as “Requesting
Shareholders
”) shall be entitled to make no more than [* * *] written requests of the Company (each, a “Demand”)
for registration under the Securities Act of an amount of Registrable Securities then held by such Requesting Shareholders that equals
or is greater than the Registrable Amount (a “Demand Registration,” and such registration statement, a “Demand
Registration Statement
”). Thereupon, the Company shall, subject to the terms of this Agreement, file the Demand Registration
Statement no later than thirty (30) days after receipt of a Demand and shall use its commercially reasonable efforts to effect the registration

the Registrable Securities which the Company has been so requested to register by the Requesting Shareholders for disposition
in accordance with the intended method of disposition stated in such Demand;

(ii)
all other Registrable Securities which the Company has been requested to register pursuant to Section 6.1(b), but
subject to Section 6.1(g); and

(iii)
all shares of Common Stock which the Company may elect to register in connection with any offering of Registrable Securities
pursuant to this Section 6.1, but subject to Section 6.1(g);

all to the extent necessary to permit the disposition (in accordance
with the intended methods thereof) of the Registrable Securities and the additional shares of Common Stock, if any, to be so registered.

Demand shall specify: (i) the aggregate number of Registrable Securities requested to be registered in such Demand Registration,

Demand to all other holders of Registrable Securities. The Company shall include in the Demand Registration covered by such Demand
all Registrable Securities with respect to which the Company has received a written request for inclusion therein within five days
after the Company’s notice required by this paragraph has been given, provided that if such five-day period ends on a
day that is not a Business Day, such period shall be deemed to end on the next succeeding Business Day. Each such written request
shall comply with the requirements of a Demand as set forth in this Section 6.1(b).

26

(c)
A Demand shall not be deemed to have been made and shall not count for purposes of the limitation on Demands in Section
6.1(a)
(i) unless the Demand Registration Statement with respect thereto has become effective and has remained effective for a period
of at least 105 days or such shorter period in which all Registrable Securities included in such Demand Registration have actually been
sold or otherwise disposed of thereunder (provided, that such period shall be extended for a period of time equal to the period
the holders of Registrable Securities refrain from selling any securities included in such registration statement at the request of the
Company or the lead managing underwriter(s) pursuant to the provisions of this Agreement) or (ii) if, after it has become effective, such
Demand Registration becomes subject, prior to 105 days after effectiveness, to any stop order, injunction, or other order or requirement
of the Commission or other Governmental Entity, other than by reason of any act or omission by the applicable Selling Shareholders.

(d)
Demand Registrations shall be on such appropriate registration form of the Commission as shall be selected by the Company
and reasonably acceptable to the Requesting Shareholders.

(e)
The Company shall not be obligated to (i) subject to Section 6.1(c), maintain the effectiveness of a registration
statement under the Securities Act filed pursuant to a Demand Registration for a period longer than 105 days or (ii) effect any Demand
Registration (A) within 90 days of a “firm commitment” Underwritten Offering in which all Demand Shareholders were offered
“piggyback” rights pursuant to Section 6.2 (subject to Section 6.2(b)) and at least 50% of the number of Registrable
Securities requested by such Demand Shareholders to be included in such Demand Registration were included, (B) within 90 days of the completion
of any other Demand Registration (including, for the avoidance of doubt, any Underwritten Offering pursuant to any Shelf Registration
Statement), (C) within 90 days of the completion of any other Underwritten Offering by the Company or any shorter period during which
the Company has agreed not to effect a registration or public offering of securities (in each case only to the extent that the Company
has undertaken contractually to the underwriters of such Underwritten Offering not to effect any registration or public offering of securities),
or (D) if, in the Company’s reasonable judgment, it is not feasible for the Company to proceed with the Demand Registration because
of the unavailability of audited or other required financial statements of the Company or any other Person; provided, that the
Company shall (I) use its commercially reasonable efforts to obtain such financial statements as promptly as practicable and (II) shall
be liable for and promptly indemnify Amazon for all Losses incurred by Amazon or its Affiliates that arise out of or relate to the unavailability
of such financial statements.

27

 

(f)
The Company shall be entitled to (i) postpone (upon written notice to the Demand Shareholders) the filing or the effectiveness
of a registration statement for any Demand Registration, (ii) cause any Demand Registration Statement to be withdrawn and its effectiveness
terminated, and (iii) suspend the use of the prospectus forming part of any registration statement, in each case in the event of a Blackout
Period until the expiration of the applicable Blackout Period. In the event of a Blackout Period under clause (ii) of the definition thereof,
the Company shall deliver to the Demand Shareholders requesting registration a certificate signed by either the chief executive officer
or the chief financial officer of the Company certifying that, in the good faith judgment of the Company, the conditions described in
clause (ii) of the definition of Blackout Period are met. Such certificate shall contain an approximation of the anticipated delay. Upon
notice by the Company to the Demand Shareholders of any such determination, each Demand Shareholder covenants that, subject to Applicable
Law, it shall keep the fact of any such notice strictly confidential, and in the case of a Blackout Period pursuant to clause (ii)(y)
of the definition of Blackout Period, promptly halt any offer, sale, trading or other Transfer by it or any of its Affiliates of any Registrable
Securities for the duration of the Blackout Period set forth in such notice (or until such Blackout Period shall be earlier terminated
in writing by the Company) and promptly halt any use, publication, dissemination or distribution of the Demand Registration Statement,
each prospectus included therein, and any amendment or supplement thereto by it and any of its Affiliates for the duration of the Blackout
Period set forth in such notice (or until such Blackout Period shall be earlier terminated in writing by the Company).

(g)
If, in connection with a Demand Registration that involves an Underwritten Offering, the lead managing underwriter(s) advise(s)
the Company that, in its (their) good faith opinion, the inclusion of all of the securities sought to be registered in connection with
such Demand Registration would adversely affect the success thereof, then the Company shall include in such registration statement only
such securities as the Company is advised by such lead managing underwriter(s) can be sold without such adverse effect as follows and
in the following order of priority: (i) first, up to the number of Registrable Securities requested to be included in such Demand Registration
by the Demand Shareholders, which, in the opinion of the lead managing underwriter(s), can be sold without adversely affecting the success
thereof, pro rata among such Demand Shareholders on the basis of the number of such Registrable Securities requested to be included by
such Demand Shareholders; (ii) second, securities the Company proposes to sell; and (iii) third, all other securities of the Company duly
requested to be included in such registration statement, pro rata on the basis of the amount of such other securities requested to be
included or such other allocation method determined by the Company.

(h)
Any time that a Demand Registration involves an Underwritten Offering, the Requesting Shareholder(s) shall select the investment
banker(s) and manager(s) that will serve as managing underwriters (including which such managing underwriters will serve as lead or co-lead)
and underwriters with respect to the offering of such Registrable Securities; provided, that such investment banker(s) and manager(s)
shall be reasonably acceptable to the Company (such acceptance not to be unreasonably withheld, conditioned, or delayed).

6.2          Piggyback Registrations.

(a)               Subject
to the terms and conditions hereof, whenever the Company proposes to register any Common Stock (or any other securities that are of
the same class or series as any Registrable Securities that are not shares of Common Stock) under the Securities Act (other than a
registration by the Company (i) on Form S-4, (ii) on Form S-8, (iii) pursuant to Section 6.3, (iv) pursuant to Section
6.1
, or (v) [* * *] (a “Piggyback Registration”), whether for its own account or for the account of others,
the Company shall give all Demand Shareholders prompt written notice thereof (but not less than ten Business Days prior to the
filing by the Company with the Commission of any registration statement with respect thereto). Such notice (a “Piggyback
Notice
”) shall specify the number of shares of Common Stock (or other securities, as applicable) proposed to be
registered, the proposed date of filing of such registration statement with the Commission, the proposed means of distribution, the
proposed managing underwriter(s) (if any), and a good faith estimate by the Company of the proposed minimum offering price of such
shares of Common Stock (or other securities, as applicable), in each case to the extent then known. Subject to Section
6.2(b)
, the Company shall include in each such Piggyback Registration all Registrable Securities held by Demand Shareholders (a
Piggyback Seller”) with respect to which the Company has received written requests (which written requests shall
specify the number of Registrable Securities requested to be disposed of by such Piggyback Seller) for inclusion therein within ten
days after such Piggyback Notice is received by such Piggyback Seller.

(b)
If, in connection with a Piggyback Registration that involves an Underwritten Offering, the lead managing underwriter(s)
advise(s) the Company that, in its opinion, the inclusion of all the securities sought to be included in such Piggyback Registration by
(w) the Company, (x) other Persons who have sought to have shares of Common Stock registered in such Piggyback Registration pursuant to
rights to demand (other than pursuant to so-called “piggyback” or other incidental or participation registration rights) such
registration (such Persons being “Other Demanding Sellers”), (y) the Piggyback Sellers, and (z) any other proposed
sellers of shares of Common Stock (such Persons being “Other Proposed Sellers”), as the case may be, would materially
and adversely affect the success thereof, then the Company shall include in the registration statement applicable to such Piggyback Registration
only such securities as the Company is so advised by such lead managing underwriter(s) can be sold without such an effect, as follows
and in the following order of priority:

(i)
if the Piggyback Registration relates to an offering for the Company’s own account, then (A) first, such number of
shares of Common Stock (or other securities, as applicable) to be sold by the Company as the Company, in its reasonable judgment, shall
have determined, (B) second, Registrable Securities of Piggyback Sellers, pro rata on the basis of the number of Registrable Securities
proposed to be sold by such Piggyback Sellers, (C) third, shares of Common Stock sought to be registered by Other Demanding Sellers, pro
rata on the basis of the number of shares of Common Stock proposed to be sold by such Other Demanding Sellers, and (D) fourth, other shares
of Common Stock proposed to be sold by any Other Proposed Sellers; or

(ii)              if
the Piggyback Registration relates to an offering other than for the Company’s own account, then (A) first, such number of
shares of Common Stock (or other securities, as applicable) sought to be registered by each Other Demanding Seller pro rata in
proportion to the number of securities sought to be registered by all such Other Demanding Sellers, (B) second, Registrable
Securities of Piggyback Sellers, pro rata on the basis of the number of Registrable Securities proposed to be sold by such Piggyback
Sellers, (C) third, shares of Common Stock to be sold by the Company, and (D) fourth, other shares of Common Stock proposed to be
sold by any Other Proposed Sellers.

29

(c)
For clarity, in connection with any Underwritten Offering under this Section 6.2 for the Company’s account,
the Company shall not be required to include the Registrable Securities of a Piggyback Seller in the Underwritten Offering unless such
Piggyback Seller accepts the terms of the underwriting as agreed upon between the Company and the lead managing underwriter(s), which
shall be selected by the Company.

(d)
If, at any time after giving written notice of its intention to register any shares of Common Stock (or other securities,
as applicable) as set forth in this Section 6.2 and prior to the time the registration statement filed in connection with such
Piggyback Registration is declared effective, the Company shall determine for any reason not to register such shares of Common Stock (or
other securities, as applicable), the Company may, at its election, give written notice of such determination to the Piggyback Sellers
within five Business Days thereof and thereupon shall be relieved of its obligation to register any Registrable Securities in connection
with such particular withdrawn or abandoned Piggyback Registration; provided, that, if permitted pursuant to Section 6.1,
the Demand Shareholders may continue the registration as a Demand Registration pursuant to the terms of Section 6.1.

6.3         Shelf
Registration Statement
.

(a)
Subject to the terms and conditions hereof, and further subject to the availability of Form S-3 to the Company, any of the
Demand Shareholders may by written notice delivered to the Company (the “Shelf Notice”) require the Company to file
as soon as reasonably practicable, and to use commercially reasonable efforts to cause to be declared effective by the Commission as soon
as reasonably practicable after such filing date, a Form S-3, providing for an offering to be made on a continuous basis pursuant to Rule
415 under the Securities Act relating to the offer and sale, from time to time, of an amount of Registrable Securities then held by such
Demand Shareholders that equals or is greater than the Registrable Amount (the “Shelf Registration Statement”). To
the extent the Company is a well-known seasoned issuer (as defined in Rule 405 under the Securities Act), the Company shall file the Shelf
Registration Statement in the form of an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) or any
successor form thereto. If registering a number of Registrable Securities, the Company shall pay the registration fee for all Registrable
Securities to be registered pursuant to an automatic shelf registration statement at the time of filing of the automatic shelf registration
statement and shall not elect to pay any portion of the registration fee on a deferred basis. The Company may also amend an existing registration
statement on Form S-3, including by post-effective amendment, in order to fulfill its obligations hereunder.

(b)               Within
five days after receipt of a Shelf Notice pursuant to Section 6.3(a), the Company will deliver written notice thereof to all
other holders of Registrable Securities. Each other holder of Registrable Securities may elect to participate with respect to its
Registrable Securities in the Shelf Registration Statement in accordance with the plan and method of distribution set forth, or to
be set forth, in such Shelf Registration Statement by delivering to the Company a written request to so participate within five days
after the Shelf Notice is received by any such holder of Registrable Securities.

30

(c)
Subject to Section 6.3(d), the Company shall use its commercially reasonable efforts to keep the Shelf Registration
Statement continuously effective until the date on which all Registrable Securities covered by the Shelf Registration Statement have been
sold thereunder in accordance with the plan and method of distribution disclosed in the prospectus included in the Shelf Registration
Statement, or otherwise cease to be Registrable Securities.

(d)
Notwithstanding anything to the contrary contained in this Agreement, the Company shall be entitled, from time to time,
by providing written notice to the holders of Registrable Securities who elected to participate in the Shelf Registration Statement, to
require such holders of Registrable Securities to suspend the use of the prospectus for sales of Registrable Securities under the Shelf
Registration Statement during any Blackout Period. In the event of a Blackout Period under clause (ii) of the definition thereof, the
Company shall deliver to the Demand Shareholders requesting registration a certificate signed by either the chief executive officer or
the chief financial officer of the Company certifying that, in the good faith judgment of the Company, the conditions described in clause
(ii) of the definition of Blackout Period are met. Such certificate shall contain an approximation of the anticipated delay. Upon notice
by the Company to the Demand Shareholders of any such determination, each Demand Shareholder covenants that it shall, subject to Applicable
Law, keep the fact of any such notice strictly confidential, and in the case of a Blackout Period pursuant to clause (ii)(y) of the definition
of Blackout Period, promptly halt any offer, sale, trading or other Transfer by it or any of its Affiliates of any Registrable Securities
for the duration of the Blackout Period set forth in such notice (or until such Blackout Period shall be earlier terminated in writing
by the Company) and promptly halt any use, publication, dissemination or distribution of the Shelf Registration Statement, each prospectus
included therein, and any amendment or supplement thereto by it and any of its Affiliates for the duration of the Blackout Period set
forth in such notice (or until such Blackout Period shall be earlier terminated in writing by the Company) and, if so directed in writing
by the Company, will deliver to the Company any copies then in the Demand Shareholder’s possession of the prospectus covering such
Registrable Securities that was in effect at the time of receipt of such notice.

(e)
After the expiration of any Blackout Period and without any further request from a holder of Registrable Securities, the
Company, to the extent necessary, shall as promptly as reasonably practicable prepare a post-effective amendment or supplement to the
Shelf Registration Statement or the prospectus, or any document incorporated therein by reference, or file any other required document
so that, as thereafter delivered to purchasers of the Registrable Securities included therein, the prospectus will not include an untrue
statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

(f)                At
any time that a Shelf Registration Statement is effective, if any Demand Shareholder delivers a notice to the Company (a
Take-Down Notice”) stating that it intends to sell all or part of its Registrable Securities included by it on
the Shelf Registration Statement (a “Shelf Offering”), then the Company shall amend or supplement the Shelf
Registration Statement as may be necessary in order to enable such Registrable Securities to be distributed pursuant to the Shelf
Offering (taking into account, solely in connection with a Marketed Underwritten Shelf Offering, the inclusion of Registrable
Securities by any other holders pursuant to this Section 6.3). In connection with any Shelf Offering that is an Underwritten
Offering and where the plan of distribution set forth in the applicable Take-Down Notice includes a customary “road
show” (including an “electronic road show”) or other substantial marketing effort by the Company and the
underwriters (a “Marketed Underwritten Shelf Offering”):

31

(i)
such proposing Demand Shareholder(s) shall also deliver the Take-Down Notice to all other Demand Shareholders included on
the Shelf Registration Statement and permit each such holder to include its Registrable Securities included on the Shelf Registration
Statement in the Marketed Underwritten Shelf Offering if such holder notifies the proposing Demand Shareholder(s) and the Company within
two Business Days after delivery of the Take-Down Notice to such holder; and

(ii)
if the lead managing underwriter(s) advises the Company and the proposing Demand Shareholder(s) that, in its opinion, the
inclusion of all of the securities sought to be sold in connection with such Marketed Underwritten Shelf Offering would materially and
adversely affect the success thereof, then there shall be included in such Marketed Underwritten Shelf Offering only such securities as
the proposing Demand Shareholder(s) is advised by such lead managing underwriter(s) can be sold without such adverse effect, and such
number of Registrable Securities shall be allocated in the same manner as described in Section 6.1(g). Except as otherwise expressly
specified in this Section 6.3, any Marketed Underwritten Shelf Offering shall be subject to the same requirements, limitations,
and other provisions of this Article VI as would be applicable to a Demand Registration (i.e., as if such Marketed Underwritten
Shelf Offering were a Demand Registration), including Section 6.1(e)(ii) and Section 6.1(g).

(g)
Notwithstanding any other provision of this Agreement, if the requesting Demand Shareholder wishes to engage in a block
sale (including a block sale off of a Shelf Registration Statement or an effective automatic shelf registration statement, or in connection
with the registration of the Registrable Securities under an automatic shelf registration statement for purposes of effectuating a block
sale), then notwithstanding the foregoing or any other provisions hereunder, no Demand Shareholder shall be entitled to receive any notice
of or have its Registrable Securities included in such block sale.

(h)
Any time that a Shelf Offering involves a Marketed Underwritten Shelf Offering, the Requesting Shareholder(s) shall select
the investment banker(s) and manager(s) that will serve as managing underwriters (including which such managing underwriters will serve
as lead or co-lead) and underwriters with respect to the offering of such Registrable Securities; provided, that such investment
banker(s) and manager(s) shall be reasonably acceptable to the Company (such acceptance not to be unreasonably withheld, conditioned,
or delayed).

32

6.4         Withdrawal
Rights
. Any holder of Registrable Securities having notified or directed the Company to include any or all of its Registrable
Securities in a registration statement under the Securities Act shall have the right to withdraw any such notice or direction with
respect to any or all of the Registrable Securities designated by it for registration by giving written notice to such effect to the
Company prior to the effective date of such registration statement. In the event of any such withdrawal, the Company shall not
include such Registrable Securities in the applicable registration and such Registrable Securities shall continue to be Registrable
Securities for all purposes of this Agreement (subject to the other terms and conditions of this Agreement). No such withdrawal
shall affect the obligations of the Company with respect to the Registrable Securities not so withdrawn; provided, however,
that in the case of a Demand Registration, if such withdrawal shall reduce the number of Registrable Securities sought to be
included in such registration below the Registrable Amount, then the Company shall as promptly as practicable give each Demand
Shareholder seeking to register Registrable Securities notice to such effect, and within five days following the delivery of such
notice, such Demand Shareholder still seeking registration shall, by written notice to the Company, elect to register additional
Registrable Securities to satisfy the Registrable Amount or elect that such registration statement not be filed, or if theretofore
filed, be withdrawn. During such five-day period, the Company shall not file such registration statement if not theretofore filed,
or if such registration statement has been theretofore filed, the Company shall not seek, and shall use commercially reasonable
efforts to prevent, the effectiveness thereof. No Demand Registration withdrawn pursuant to this Section 6.4 shall count
against the number of Demands which may have been made under Section 6.1(a) hereof.

6.5          Hedging Transactions.

(a)
The provisions of this Agreement relating to the registration, offer, and sale of Registrable Securities shall apply also
to (i) any transaction which Transfers some or all of the economic risk of ownership of Registrable Securities, including any forward
contract, equity swap, put or call, put- or call-equivalent position, collar, margin loan, sale of exchangeable security, or similar transaction
(including the registration, offer, and sale under the Securities Act of Registrable Securities pledged to the counterparty to such transaction
or of securities of the same class as the underlying Registrable Securities by the counterparty to such transaction in connection therewith),
and that the counterparty to such transaction shall be selected in the sole discretion of the Demand Shareholders and (ii) any derivative
transactions in which a broker-dealer, other financial institution, or unaffiliated Person (each, a “Hedging Counterparty”)
may sell Registrable Securities covered by any prospectus and the applicable prospectus supplement including short sale transactions using
Registrable Securities pledged by a Demand Shareholder or borrowed from the Demand Shareholder or others and Registrable Securities loaned,
pledged, or hypothecated to any such party (each, a “Hedging Transaction”); provided that the Demand Shareholder’s
legal counsel has determined in its reasonable judgment (after good faith consultation with counsel of the Company) that it is reasonably
necessary to register under the Securities Act such Hedging Transaction. Any written information regarding the Hedging Transaction provided
to the Company by a Hedging Counterparty for inclusion in any registration statement, prospectus, or free writing prospectus filed pursuant
to this Section 6.5 shall, for purposes of Section 6.10(b), be deemed to be written information provided by a Selling Shareholder
for purposes of Section 6.10(b).

33

(b)               If
in connection with a Hedging Transaction, a Hedging Counterparty or any Affiliate thereof is (or may reasonably be considered) an
underwriter or selling shareholder, then such Hedging Counterparty shall be required to provide customary indemnities to the Company
regarding the plan of distribution and related matters.

(c)
Notwithstanding any other provision of this Section 6.5, in no event shall Amazon or any of its Affiliates “loan”
any Registrable Securities to “short sellers” of the Company’s securities.

6.6           Holdback
Agreements
.

(a)
Amazon shall enter into customary agreements restricting the sale or distribution of Equity Securities of the Company (including
sales pursuant to Rule 144 under the Securities Act) to the extent required by the lead managing underwriter(s) with respect to an applicable
Underwritten Offering in which Amazon participates during the period commencing on the date of the request (which shall be no earlier
than 14 days prior to the expected “pricing” of such Underwritten Offering) and continuing for not more than 90 days after
the date of the “final” prospectus (or “final” prospectus supplement if the Underwritten Offering is made pursuant
to a Shelf Registration Statement), pursuant to which such Underwritten Offering shall be made. The Company shall not include Registrable
Securities of any other Demand Shareholder in such an Underwritten Offering unless such other Demand Shareholder enters into a customary
agreement restricting the sale or distribution of Equity Securities of the Company (including sales pursuant to Rule 144 under the Securities
Act) if requested by the lead managing underwriter(s).

(b)
If any Demand Registration or Shelf Offering involves an Underwritten Offering, the Company will not effect any sale or
distribution of shares of Common Stock (or securities convertible into or exchangeable or exercisable for shares of Common Stock) (other
than a Form S-4 or Form S-8) for its own account within 60 days (plus an extension period as may be proposed by the lead managing underwriter(s)
for such Underwritten Offering to address FINRA regulations regarding the publication of research, or such shorter periods as the lead
managing underwriter(s) may agree with the Company) after the effective date of such registration except as may otherwise be agreed between
the Company and the lead managing underwriter(s) of such Underwritten Offering.

6.7          Registration Procedures.

(a)
If and whenever the Company is required to use commercially reasonable efforts to effect the registration of any Registrable
Securities under the Securities Act as provided in Section 6.1, Section 6.2 or Section 6.3, the Company shall as
expeditiously as reasonably practicable:

34

(i)                 prepare
and file with the Commission a registration statement to effect such registration in accordance with the intended method or methods
of distribution of such securities and thereafter use commercially reasonable efforts to cause such registration statement to become
and remain effective pursuant to the terms of this Article VI; provided, however, that the Company may
discontinue any registration of its securities which are not Registrable Securities at any time prior to the effective date of the
registration statement relating thereto; provided, further, that before filing such registration statement or any
amendments thereto, the Company will furnish to the Demand Shareholders, which are including Registrable Securities in such
registration (“Selling Shareholders”), their counsel and the lead managing underwriter(s), if any, copies of all
such documents proposed to be filed, which documents will be subject to the review and reasonable comment of such counsel, and other
documents reasonably requested by such counsel, including any comment letter from the Commission, and, if requested by such counsel,
the Company will provide such counsel reasonable opportunity to participate in the preparation of such registration statement and
each prospectus included therein and such other opportunities to conduct a reasonable investigation within the meaning of the
Securities Act, including reasonable access to the Company’s books and records, officers, accountants, and other advisors. The
Company shall not file any such registration statement or prospectus or any amendments or supplements thereto with respect to a
Demand Registration to which the holders of a majority of Registrable Securities held by the Requesting Shareholder(s), their
counsel, or the lead managing underwriter(s), if any, shall reasonably object, in writing, on a timely basis, unless, in the opinion
of the Company, such filing is necessary to comply with Applicable Law;

(ii)
except in the case of a Shelf Registration Statement, prepare and file with the Commission such amendments, including post-effective
amendments, and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep

of the Securities Act with respect to the disposition of all securities covered by such registration statement;

(iii)
in the case of a Shelf Registration Statement, prepare and file with the Commission such amendments, including post-effective
amendments, and supplements to such Shelf Registration Statement and the prospectus used in connection therewith as may be necessary to
keep such Shelf Registration Statement effective and to comply in all material respects with the provision of the Securities Act with
respect to the disposition of the Registrable Securities subject thereto for a period ending on the date on which all the Registrable
Securities held by the Demand Shareholders cease to be Registrable Securities;

(iv)
if requested by the lead managing underwriter(s), if any, or the holders of a majority of the then outstanding Registrable
Securities being sold in connection with an Underwritten Offering, promptly include in a prospectus supplement or post-effective amendment
such information as the lead managing underwriter(s), if any, and such holders may reasonably request in order to permit the intended
method of distribution of such securities and make all required filings of such prospectus supplement or such post-effective amendment
as soon as reasonably practicable after the Company has received such request; provided, however, that the Company shall
not be required to take any actions under this Section 6.7(a)(iv) that are not, in the good faith written opinion of outside counsel
for the Company, in compliance with Applicable Law;

35

(v)
furnish to the Selling Shareholders and each underwriter, if any, of the securities being sold by such Selling Shareholders
such number of conformed copies of such registration statement and of each amendment and supplement thereto, such number of copies of
the prospectus contained in such registration statement (including each preliminary prospectus and any summary prospectus) and each free
writing prospectus (as defined in Rule 405 of the Securities Act) (a “Free Writing Prospectus”) utilized in connection
therewith and any other prospectus filed under Rule 424 under the Securities Act, in conformity with the requirements of the Securities
Act, and such other documents as such Selling Shareholders and underwriter, if any, may reasonably request in order to facilitate the
public sale or other disposition of the Registrable Securities owned by such Selling Shareholders;

(vi)
use commercially reasonable efforts to (I) register or qualify or cooperate with the Selling Shareholders, the underwriters,
if any, and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification)
of such Registrable Securities covered by such registration statement under such other securities laws or “blue sky” laws
of such jurisdictions as the Selling Shareholders and any underwriter of the securities being sold by such Selling Shareholders shall
reasonably request, (II) keep each such registration or qualification (or exemption therefrom) effective during the period such registration
statement is required to be kept effective, and (III) take any other action which may be necessary or reasonably advisable to enable such
Selling Shareholders and underwriters to consummate the disposition in such jurisdictions of the Registrable Securities owned by such
Selling Shareholders, except that the Company shall not for any such purpose be required to (A) qualify generally to do business as a
foreign corporation in any jurisdiction wherein it would not but for the requirements of this clause (vi) be obligated to be so qualified,
(B) subject itself to taxation in any such jurisdiction, or (C) file a general consent to service of process in any such jurisdiction;

(vii)
use commercially reasonable efforts to cause such Registrable Securities (if such Registrable Securities are shares of Common
Stock) to be listed on each securities exchange on which shares of Common Stock are then listed;

(viii)
use commercially reasonable efforts to provide and cause to be maintained a transfer agent and registrar for all Registrable
Securities covered by such registration statement from and after a date not later than the effective date of such registration statement;

(ix)             enter
into such agreements (including an underwriting agreement) in form, scope, and substance as is customary in underwritten offerings
of shares of Common Stock by the Company and use its commercially reasonable efforts to take all such other actions reasonably
requested by the holders of a majority of the Registrable Securities being sold in connection therewith (including those reasonably
requested by the lead managing underwriter(s), if any) to expedite or facilitate the disposition of such Registrable Securities, and
in such connection, whether or not an underwriting agreement is entered into and whether or not the registration is an Underwritten
Offering, (A) the Company shall make such representations and warranties to the holders of such Registrable Securities and the
underwriters, if any, with respect to the business of the Company and its subsidiaries and the registration statement, prospectus,
and documents, if any, incorporated or deemed to be incorporated by reference therein, in each case, in form, substance, and scope
as customarily made by issuers in underwritten offerings, and, if true, confirm the same if and when requested, (B) if any
underwriting agreement has been entered into, the same shall contain customary indemnification provisions and procedures with
respect to all parties to be indemnified pursuant to Section 6.10, except as otherwise agreed by the holders of a majority of
the Registrable Securities being sold, and (C) the Company shall deliver such documents and certificates as reasonably requested by
the holders of a majority of the Registrable Securities being sold, their counsel and the lead managing underwriter(s), if any, to
evidence the continued validity of the representations and warranties made pursuant to sub-clause (A) above and to evidence
compliance with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company. The
above shall be done at each closing under such underwriting or similar agreement, or as and to the extent required thereunder;

36

(x)
in connection with an Underwritten Offering, use commercially reasonable efforts to obtain for the underwriter(s) (A) opinions
of counsel for the Company, covering the matters customarily covered in opinions requested in underwritten offerings and such other matters
as may be reasonably requested by such underwriters and (B) “comfort” letters and updates thereof (or, in the case of any
such Person which does not satisfy the conditions for receipt of a “comfort” letter specified in Statement on Auditing Standards
No. 72, an “agreed upon procedures” letter) signed by the independent public accountants who have certified the Company’s
financial statements included in such registration statement, covering the matters customarily covered in “comfort” letters
in connection with underwritten offerings;

(xi)             make
available for inspection by the Selling Shareholders any underwriter participating in any disposition pursuant to any registration
statement and any attorney, accountant, or other agent or Representative retained in connection with such offering by such Selling
Shareholders or underwriter (collectively, the “Inspectors”), financial and other records, pertinent corporate
documents and properties of the Company (collectively, the “Records”), as shall be reasonably necessary, or as
shall otherwise be reasonably requested, to enable them to exercise their due diligence responsibility, and the Company shall cause
the officers, directors, and employees of the Company and its subsidiaries to supply all information in each case reasonably
requested by any such Representative, underwriter, attorney, agent, or accountant in connection with such registration statement; provided, however,
that the Company shall not be required to provide any information under this Section 6.7(a)(xi) if (A) the Company believes,
after advice of outside counsel for the Company, that to do so would cause the Company to forfeit an attorney-client privilege that
was applicable to such information or (B) either (1) the Company has requested and been granted from the Commission confidential
treatment of such information contained in any filing with the Commission or documents provided supplementally or otherwise or (2)
the Company reasonably determines in good faith that such Records are confidential and so notifies the Inspectors in writing, unless
prior to furnishing any such information with respect to the foregoing clause (1) or (2) such Selling Shareholder requesting such
information enters into, and causes each of its Inspectors to enter into, a confidentiality agreement on terms and conditions
reasonably acceptable to the Company; provided, further, that each Selling Shareholder agrees that it will, upon
learning that disclosure of such Records is sought in a court of competent jurisdiction or by another Governmental Entity, give
written notice to the Company and allow the Company, at its expense, to undertake appropriate action seeking to prevent disclosure
of the Records deemed confidential;

37

(xii)
as promptly as practicable notify in writing the Selling Shareholders and the underwriters, if any, of the following events:
(A) the filing of the registration statement, any amendment thereto, the prospectus or any prospectus supplement related thereto or post-effective
amendment to the registration statement or any Free Writing Prospectus utilized in connection therewith, and, with respect to the registration
statement or any post-effective amendment thereto, when the same has become effective; (B) any request by the Commission or any other
Governmental Entity for amendments or supplements to the registration statement or the prospectus or for additional information; (C) the
issuance by the Commission of any stop order suspending the effectiveness of the registration statement or the initiation of any proceedings

and each Person who controls (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) such
Selling Shareholder or such other indemnified Person and the officers, directors, members, shareholders, employees, managers, and
partners of each such controlling Person, each underwriter, if any, and each Person who controls (within the meaning of Section 15

registration statement, prospectus, or preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto or
any omission (or alleged omission) of a material fact required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading and (without limitation of the preceding portions of this Section
6.10(a)
) will reimburse each such Selling Shareholder, each of its Affiliates, and each of their respective officers, directors,
members, shareholders, employees, managers, and partners and each such Person who controls each such Selling Shareholder and the
officers, directors, members, shareholders, employees, managers, partners, accountants, attorneys, and agents of each such
controlling Person, each such underwriter, and each such Person who controls any such underwriter for any reasonable, customary and
reasonably documented legal and other expenses incurred in connection with investigating and defending or settling any such claim,
Loss, damage, liability, or action, except insofar as the same are caused by any information furnished in writing to the Company by
any Selling Shareholder expressly for use therein.

41

(b)
In connection with any registration statement in which a Selling Shareholder is participating, without limitation as to
time, each such Selling Shareholder shall, severally and not jointly, indemnify the Company, its directors, officers, and employees and
each Person who controls (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) the Company from
and against all Losses, as incurred, arising out of, caused by, resulting from, or relating to any untrue statement (or alleged untrue
statement) of material fact contained in the registration statement, prospectus, or preliminary prospectus or Free Writing Prospectus
or any amendment or supplement thereto or any omission (or alleged omission) of a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they were made, not misleading and (without limitation of the
preceding portions of this Section 6.10(b)) will reimburse the Company, its directors, officers, and employees and each Person
who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) for any reasonable,
customary, and reasonably documented legal and other expenses incurred in connection with investigating and defending or settling any
such claim, Loss, damage, liability, or action, in each case solely to the extent, but only to the extent, that such untrue statement
or omission is made in such registration statement, prospectus, or preliminary prospectus or Free Writing Prospectus or any amendment
or supplement thereto in reliance upon and in conformity with written information furnished to the Company by such Selling Shareholder
for inclusion in such registration statement, prospectus, or preliminary prospectus or Free Writing Prospectus or any amendment or supplement
thereto. Notwithstanding the foregoing, no Selling Shareholder shall be liable under this Section 6.10(b) for amounts in excess
of the gross proceeds (after deducting any underwriting discount or commission) received by such holder from its sale of Registrable Securities
in connection with the offering that gave rise to such liability.

(c)
Any Person entitled to indemnification hereunder shall give prompt written notice to the indemnifying party of any claim
with respect to which it seeks indemnification; provided, however, the failure to give such notice shall not release the
indemnifying party from its obligation, except to the extent that the indemnifying party has been actually and materially prejudiced by
such failure to provide such notice on a timely basis.

42

(d)               In
any case in which any such action is brought against any indemnified party, and it notifies an indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, to assume
the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to
such indemnified party of its election so to assume the defense thereof and acknowledging the obligations of the indemnifying party
with respect to such proceeding, the indemnifying party will not (so long as it shall continue to have the right to defend, contest,
litigate, and settle the matter in question in accordance with this paragraph) be liable to such indemnified party hereunder for any
legal or other expense subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable
costs of investigation, supervision, and monitoring (unless (i) such indemnified party reasonably objects to such assumption on the
grounds that (A) there may be defenses available to it which are different from or in addition to the defenses available to such
indemnifying party or (B) such action involves, or is reasonably likely to have an effect beyond, the scope of matters that are
subject to indemnification pursuant to this Section 6.10, or (ii) the indemnifying party shall have failed within a
reasonable period of time to assume such defense and the indemnified party is or would reasonably be expected to be materially
prejudiced by such delay, and in either event the indemnified party shall be promptly reimbursed by the indemnifying party for the
expenses incurred in connection with retaining one separate legal counsel (for the avoidance of doubt, for all indemnified parties
in connection therewith)). For the avoidance of doubt, notwithstanding any such assumption by an indemnifying party, the indemnified
party shall have the right to employ separate counsel in any such matter and participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party except as provided in the previous sentence. An
indemnifying party shall not be liable for any settlement of an action or claim effected without its consent. No matter shall be
settled by an indemnifying party without the consent of the indemnified party (which consent shall not be unreasonably withheld,
conditioned, or delayed), unless such settlement (x) includes as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation, (y) does not include any
statement as to or any admission of fault, culpability, or a failure to act by or on behalf of any indemnified party, and (z) is
settled solely for cash for which the indemnified party would be entitled to indemnification hereunder.

(e)
The indemnification provided for under this Agreement shall survive the Transfer of the Registrable Securities and the termination
of this Agreement.

(f)                If
recovery is not available under the foregoing indemnification provisions for any reason or reasons other than as specified therein,
any Person who would otherwise be entitled to indemnification by the terms thereof shall nevertheless be entitled to contribution
with respect to any Losses with respect to which such Person would be entitled to such indemnification but for such reason or
reasons, in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and such
indemnified party, on the other hand, 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 the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to
state a material fact relates to information supplied by the indemnifying party or by the indemnified party, the Persons’
relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to
correct and prevent any statement or omission, and other equitable considerations appropriate under the circumstances. It is hereby
agreed that it would not necessarily be equitable if the amount of such contribution were determined by pro rata or per capita
allocation. 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 found guilty of such fraudulent misrepresentation. Notwithstanding the
foregoing, no Selling Shareholder shall be required to make a contribution in excess of the gross proceeds (after deducting any
underwriting discount or commission) received by such Selling Shareholder from its sale of Registrable Securities in connection with
the offering that gave rise to the contribution obligation.

43

Free Writing Prospectuses. No Selling Shareholder shall use any “free writing prospectus” (as defined
in Rule 405 under the Securities Act) in connection with the sale of Registrable Securities pursuant to this Article VI without
the prior written consent of the Company (which consent shall not be unreasonably withheld, conditioned, or delayed). Notwithstanding
the foregoing, a Selling Shareholder may use any free writing prospectus prepared and distributed by the Company.

6.12
Termination of Registration Rights. The rights granted pursuant to this Article VI shall terminate, as to
any holder of Registrable Securities, on the date on which all Registrable Securities held by such holder have been disposed, including
all shares issued or issuable upon exercise of the Warrant.

Clean Energy Signs Agreement with Amazon for
Low and Negative Carbon RNG

NEWPORT BEACH, Calif. – April 19, 2021 – Clean
Energy Fuels Corp. (Nasdaq: CLNE) today announced that it has signed an agreement with Amazon (Nasdaq: AMZN) to provide low and negative
carbon renewable natural gas (RNG). The fuel will be provided at 27 existing Clean Energy fueling stations and another 19 non-exclusive
new or upgraded Clean Energy-owned stations that Clean Energy expects to be constructed by the end of the year. The new and existing
stations will provide RNG in 15 different states.

“If the world is really going to tackle the issue of climate
change, all of us need to find solutions that work both environmentally and economically, and that is exactly what this agreement supports,”
said Andrew J. Littlefair, CEO and president of Clean Energy. “Clean Energy was the first to commercially make RNG available as
a vehicle fuel in 2013 and now fuels tens of thousands of vehicles across the country every day.”

In addition, the company has issued a warrant to Amazon. For more information,
refer to Clean Energy’s Form 8-K.
