Except as provided in this Section 2(b), there shall be no limitation on the number of takedowns off the Shelf Registration Statement.

(a) Right to Request Registration. Any time following one (1) year after completion of an initial public offering of Ordinary Shares (an “IPO”) and at a time when the Company is not eligible to file a registration statement under the Securities Act on Form F-3 or Form S-3 (or any successor form thereto), the Investor may request registration for resale under the Securities Act of all or part of the Registrable Ordinary Shares pursuant to a Registration Statement separate from the Shelf Registration Statement (a “Demand Registration”).

(c) Priority on Demand Registrations. If a Demand Registration pursuant to this Section 3 involves an underwritten offering and the managing underwriter shall advise the Company that in its opinion the number of securities requested to be included in such registration exceeds the number that can be sold in such offering without having an adverse effect on such offering, including the price at which such securities can be sold, then the Company shall include in such registration the maximum number of shares that such underwriter advises can be so sold without having such effect, allocated (i) first, to Registrable Ordinary Shares requested by the Investor to be included in such registration and (ii) second, among all Ordinary Shares requested to be included in such registration by any other Persons (including securities to be sold for the account of the Company) allocated among such Persons in such manner as they may agree.

4

(d) Restrictions on Demand Registrations. The Company may postpone the filing or the effectiveness of a Demand Registration Statement if, based on the good faith judgment of the Company’s Board of Directors, such postponement is necessary in order to avoid premature disclosure of a matter the Board of Directors has determined would not be in the best interest of the Company to be disclosed at such time; provided, however, that the Investor shall be entitled, at any time after receiving notice of such postponement and before such Demand Registration Statement becomes effective, to withdraw such request and, if such request is withdrawn, such Demand Registration shall not count as one of the permitted Demand Registrations. The Company shall provide written notice to the Investor of (x) any postponement of the filing or effectiveness of a Demand Registration Statement pursuant to this Section 3(d), (y) the Company’s decision to file or seek effectiveness of such Demand Registration Statement following such postponement and (z) the effectiveness of such Demand Registration Statement. The Company may defer the filing or effectiveness of a particular Demand Registration Statement pursuant to this Section 3(d) only once during any 12-month period. Notwithstanding the provisions of this Section 3(d), the Company may not postpone the filing or effectiveness of a Demand Registration Statement past the date that is the earliest of (a) the date upon which any disclosure of a matter the Board of Directors has determined would not be in the best interest of the Company to be disclosed is disclosed to the public or ceases to be material, (b) thirty (30) days after the date upon which the Board of Directors has determined such matter should not be disclosed and (c) such date that, if such postponement continued, would result in there being more than 45 days in the aggregate in any 12 month period during which the filing or effectiveness of one or more Registration Statements has been so postponed. The period during which filing or effectiveness is so postponed hereunder is referred to as a “Delay Period.”

(e) Effective Period of Demand Registrations. After any Demand Registration filed pursuant to this Agreement has become effective, the Company shall use its commercially reasonable best efforts to keep such Demand Registration Statement effective for a period of at least 180 days from the date on which the SEC declares such Demand Registration Statement effective plus the duration of any Delay Period and any Blackout Period, or such shorter period that shall terminate when all of the Registrable Ordinary Shares covered by such Demand Registration Statement has been sold pursuant to such Demand Registration Statement in accordance with the plan of distribution set forth therein.

(a) Right to Piggyback. If at any time following the completion of an IPO, the Company proposes to publicly sell or register for sale any of its equity securities pursuant to a registration statement (a “Piggyback Registration Statement”) under the Securities Act (other than a registration statement on Form F-8 or on Form F-4 or any similar successor forms thereto), whether for its own account or for the account of one or more securityholders of the Company (a “Piggyback Registration”), the Company shall give prompt written notice to the Investor of its intention to effect such sale or registration and, subject to Sections 4(b) and 4(c), shall include in such transaction all Registrable Ordinary Shares with respect to which the Company has received a written request from the Investor for inclusion therein within 15 days after the receipt of the Company’s notice. The Company may postpone or withdraw the filing or the effectiveness of a Piggyback Registration at any time in its sole discretion, without prejudice to the Investor’s right

5

to immediately request a Demand Registration or Shelf Registration Statement hereunder. A Piggyback Registration shall not be considered (i) a Demand Registration for purposes of Section 3 of this Agreement if the Investor was unable to register and sell all of the Registrable Ordinary Shares requested to be included in such registration or (ii) a Shelf Registration Statement for purposes of Section 2 of this Agreement.

(b) Priority on Primary Registrations. If a Piggyback Registration is initiated as an underwritten primary offering on behalf of the Company where the primary use of proceeds does not include the repurchase, redemption or retirement of capital shares of the Company (a “Stock Repurchase”), and the managing underwriter advises the Company in writing that in its opinion the number of securities requested to be included in such offering exceeds the number that can be sold in such offering without having an adverse effect on such offering, including the price at which such securities can be sold, then the Company shall include in such offering the maximum number of shares that such underwriter advises can be so sold without having such effect, allocated (i) first, to the securities the Company proposes to sell, (ii) second, to the Registrable Ordinary Shares requested to be included therein by the Investor, and (iii) third, among other securities requested to be included in such registration by other security holders of the Company on such basis as such holders may agree among themselves and the Company.

(c) Priority on Secondary Registrations. If a Piggyback Registration is initiated as an underwritten offering on behalf of a holder of the Company’s securities other than Registrable Ordinary Shares or on behalf of the Company where the use of proceeds includes a Stock Repurchase, and the managing underwriter advises the Company in writing that in its opinion the number of securities requested to be included in such offering exceeds the number that can be sold in such offering without having an adverse effect on such offering, including the price at which such securities can be sold, then the Company shall include in such offering the maximum number of shares that such underwriter advises can be so sold without having such effect, allocated (i) first, to the securities requested to be included therein by the holder(s) requesting such registration and the Registrable Ordinary Shares requested to be included therein, pro rata among the holders of such securities on the basis of the number of shares requested to be included therein and (ii) second, to other securities (including Registrable Ordinary Shares) requested to be included by other security holders, the Company and the Investor, pro rata among such holder(s), the Company and the Investor on the basis of the number of shares requested to be included by them.

The Company shall not grant to any Person the right, other than as set forth herein and except to employees of the Company with respect to registrations on Form F-8 (or any successor forms thereto), to request the Company to register any securities of the Company except such rights as are not more favorable than or inconsistent with the rights granted to the Investor and that do not adversely affect the priorities set forth herein of the Investor.

6

If any of the Registrable Ordinary Shares covered by a Demand Registration Statement or a Shelf Registration Statement (but not a Piggyback Registration) are to be sold in an underwritten offering, the Investor shall have the right to select the managing underwriter(s) to administer the offering subject to the prior approval of the Company, which approval shall not be unreasonably withheld.

The Company agrees not to, and shall exercise its commercially reasonable best efforts to obtain agreements (in the underwriters’ customary form) from its directors and executive officers not to, directly or indirectly offer, sell, pledge, contract to sell, (including any short sale), grant any option to purchase or otherwise dispose of any equity securities of the Company or enter into any hedging transaction relating to any equity securities of the Company during the 90 days beginning on the effective date of any Demand Registration Statement involving an underwritten offering or any Piggyback Registration Statement involving an underwritten offering or the pricing date of any underwritten offering pursuant to any Registration Statement (except as part of such underwritten offering or pursuant to registrations on Form F-8 or F-4 or any successor forms thereto) unless the underwriter managing the offering otherwise agrees to a shorter period; provided that, any such holdback agreements may contain exceptions for existing 10b5-1 trading plans, unless the managing underwriter shall advise the Company that in its opinion such exception will have an adverse effect on the relevant offering.

(a) In connection with the registration and sale of Registrable Ordinary Shares pursuant to this Agreement, the Company shall use its commercially reasonable best efforts to effect the registration and the sale of such Registrable Ordinary Shares in accordance with the Investor’s intended methods of disposition thereof, and pursuant thereto the Company shall as expeditiously as possible:

(i) prepare and file with the SEC a Registration Statement with respect to such Registrable Ordinary Shares and use its commercially reasonable best efforts to cause such Registration Statement to become effective as soon as practicable thereafter; and before filing a Registration Statement or Prospectus or any amendments or supplements thereto (including any prospectus supplement for a shelf takedown), furnish to the Investor and the underwriter(s), if any, copies of all such documents proposed to be filed, including documents incorporated by reference in the Prospectus and, if requested by the Investor, the exhibits incorporated by reference, and the Investor (and the underwriter(s), if any) shall have the opportunity to review and comment thereon, and the Company will make such changes and additions thereto as reasonably requested by the Investor (and the underwriter(s), if any) prior to filing any Registration Statement or amendment thereto or any Prospectus or any supplement thereto;

7

(ii) prepare and file with the SEC such amendments and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement effective for a period of not less than 180 days, in the case of a Demand Registration Statement or an aggregate of three years, in the case of a Shelf Registration Statement (plus, in each case, the duration of any Delay Period and any Blackout Period), or such shorter period as is necessary to complete the distribution of the securities covered by such Registration Statement and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended methods of disposition by the Investor thereof set forth in such Registration Statement and, in the case of the Shelf Registration Statement, prepare such prospectus supplements containing such disclosures as may be reasonably requested by the Investor or any underwriter(s) in connection with each shelf takedown;

(iii) furnish to the Investor such number of copies of such Registration Statement, each amendment and supplement thereto, each Prospectus (including each preliminary Prospectus and Prospectus supplement) and such other documents as the Investor and any underwriter(s) may reasonably request in order to facilitate the disposition of the Registrable Ordinary Shares, provided, however, that the Company shall have no such obligation to furnish copies of a final prospectus if the conditions of Rule 172(c) under the Securities Act are satisfied by the Company;

(iv) use its commercially reasonable best efforts to register or qualify such Registrable Ordinary Shares under such other securities or blue sky laws of such jurisdictions (domestic or foreign) as the Investor and any underwriter(s) reasonably requests and do any and all other acts and things that may be reasonably necessary or advisable to enable the Investor and any underwriter(s) to consummate the disposition in such jurisdictions of the Registrable Ordinary Shares (provided, that the Company will not be required to (1) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph (iv), (2) subject itself to taxation in any such jurisdiction or (3) consent to general service of process in any such jurisdiction);

(v) notify the Investor and any underwriter(s), at any time when a Prospectus relating thereto is required to be delivered under the Securities Act, of the occurrence of any event as a result of which any Prospectus contains an untrue statement of a material fact or omits any material fact necessary to make the statements therein not misleading, and, at the request of the Investor or any underwriter(s), the Company shall prepare a supplement or amendment to such Prospectus so that, as thereafter supplemented and/or amended, such Prospectus shall not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading;

(vi) in the case of an underwritten offering, (i) enter into such agreements (including underwriting agreements in customary form), (ii) take all such other actions as the Investor or the underwriter(s) reasonably request in order to expedite or facilitate the disposition of such Registrable Ordinary Shares (including, without limitation, causing senior management and other Company personnel to cooperate with the Investor and the underwriter(s) in connection with performing due diligence) and (iii) cause its counsel to issue opinions of counsel and negative assurance letters in form, substance and scope as are customary in primary underwritten offerings, addressed and delivered to the underwriter(s) and the Investor;

8

(viii) make available for inspection by the Investor, any underwriter participating in any disposition pursuant to a Registration Statement, and any attorney, accountant or other agent retained by the Investor or underwriter, all financial and other records, corporate documents and properties of the Company, and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by the Investor, underwriter, attorney, accountant or agent in connection with such Registration Statement;

(ix) use its commercially reasonable best efforts to cause all such Registrable Ordinary Shares to be listed on each securities exchange on which securities of the same class issued by the Company are then listed or, if no such similar securities are then listed, on Nasdaq or the NYSE or other national securities exchange selected by the Company;

(xiii) promptly notify the Investor and the underwriter(s), if any:

10

(e) The Investor agrees that, upon notice from the Company of the happening of any event as a result of which the Prospectus included (or deemed included) in such Registration Statement contains an untrue statement of a material fact or omits any material fact necessary to make the statements therein not misleading (a “Suspension Notice”), the Investor will forthwith discontinue disposition of Registrable Ordinary Shares pursuant to such Registration Statement for a reasonable length of time not to exceed 10 days (not to exceed 30 days in the case of an event described in Section 3(d)) until the Investor is advised in writing by the Company that the use of the Prospectus may be resumed and is furnished with a supplemented or amended Prospectus as contemplated by Section 8(a) hereof; provided, however, that such postponement of sales of Registrable Ordinary Shares by the Investor shall not exceed forty-five (45) days in the aggregate in any 12 month period.

(a) All expenses incident to the Company’s performance of or compliance with this Agreement, including, without limitation, all registration and filing fees (including SEC registration fees and FINRA filing fees), fees and expenses of compliance with securities or blue sky laws, listing application fees, printing expenses, transfer agent’s and registrar’s fees, cost of distributing Prospectuses in preliminary and final form as well as any supplements thereto, and fees and disbursements of counsel for the Company and all accountants and other Persons retained by the Company (all such expenses being herein called “Registration Expenses”) (but not including any underwriting discounts or commissions or transfer taxes, if any, attributable to the resale of Registrable Ordinary Shares), shall be borne by the Company. In addition, the Company shall pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which they are to be listed.

11

(b) The Company shall pay, or shall reimburse the Investor for, the costs and expenses of any “road show” and other customary marketing activities and for the reasonable fees and disbursements of one law firm chosen by the Investor as its counsel in connection with each Registration Statement and sale of Registrable Ordinary Shares pursuant thereto.

(c) The obligation of the Company to bear the expenses described in Section 9(a) and to pay or reimburse the Investor for the expenses described in Section 9(b) shall apply irrespective of whether any sales of Registrable Ordinary Shares ultimately take place.

(a) The Company shall indemnify, to the fullest extent permitted by law, the Investor and its officers, directors, employees and Affiliates and each Person who controls the Investor (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses arising out of or based upon any untrue or alleged untrue statement of material fact contained in any Registration Statement, the IPO registration statement, Prospectus, preliminary Prospectus or any “issuer free writing prospectus” (as defined in Securities Act Rule 433) or any amendment thereof 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 not misleading or any violation or alleged violation by the Company of the Securities Act, the Exchange Act or applicable “blue sky” laws, except insofar as the same are made in reliance on and in conformity with information relating to the Investor furnished in writing to the Company by the Investor expressly for use therein. In connection with an underwritten offering, the Company shall indemnify such underwriter(s), their officers, employees and directors and each Person who controls such underwriter(s) (within the meaning of the Securities Act) at least to the same extent as provided above with respect to the indemnification of the Investor.

(b) In connection with any Registration Statement in which the Investor is participating, the Investor shall furnish to the Company in writing such information as the Company reasonably determines, based on the advice of counsel, is required to be included in any such Registration Statement or Prospectus and shall indemnify, to the fullest extent permitted by law, the Company, its officers, employees, directors, Affiliates, and each Person who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses arising out of or based upon any untrue or alleged untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof 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 not misleading, but only to the extent that the same are made in reliance on and in conformity with information relating to the Investor furnished in writing to the Company by the Investor expressly for use therein.

(c) Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying

12

party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (in addition to any local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party there may be one or more legal or equitable defenses available to such indemnified party that are in addition to or may conflict with those available to another indemnified party with respect to such claim. Failure to give prompt written notice shall not release the indemnifying party from its obligations hereunder.

(d) The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the transfer of securities.

(e) If the indemnification provided for in or pursuant to this Section 10 is due in accordance with the terms hereof, but is held by a court to be unavailable or unenforceable in respect of any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified Person as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that result in such losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of the indemnifying party on the one hand and of the indemnified Person on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party, and by such party’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. In no event shall the liability of the Investor be greater in amount than the amount of net proceeds received by the Investor upon such sale.

(a) Rule 144 Compliance. Following an IPO (or any other transaction or event as a result of which the Company becomes subject to the periodic reporting requirements of the Exchange Act), the Company covenants that it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder, and it will take such further action as the Investor may reasonably request to make available adequate current public information with respect to the Company meeting the current public information requirements of Rule 144, to the extent required to enable the Investor to sell Registrable Ordinary Shares without registration under the Securities Act in accordance with Rule 144. Upon the request of the Investor, the Company will deliver to the Investor a written statement as to whether it has complied with such information and requirements. At any time after that date hereof, to the extent that Rule 144 is available for the public resale by the Investor of Ordinary

13

Shares or other securities issued by the Company held by the Investor, the Company will cause to be removed any restrictive legends, stop transfer instructions or similar restrictions on transfer with respect to such securities (and, if required by any transfer agent or other Person, cause its counsel to deliver a letter or opinion to the effect that the same may be removed).

(b) Termination of Registration Rights. The right of the Investor to request registration or inclusion of Registrable Ordinary Shares in any registration pursuant to Sections 2 through 4 shall not apply at any time following consummation of the IPO when, in reasonable opinion of counsel to the Investor after consultation with counsel to the Company, Rule 144 or another similar exemption under the Securities Act is then available for the unlimited public sale of all of the Investors Registrable Ordinary Shares in the United States without registration under the Securities Act and without any volume or manner of sale limitations; provided that such rights shall nevertheless continue to apply if it is reasonably likely (after consultation with a U.S. nationally recognized investment banking firm) that the sale by the Investor of all of such securities in to the public market at that time in an unmanaged transaction or transactions would have a material adverse effect on the market price of the equity securities of the Company.

(a) In connection with a transfer of Registrable Ordinary Shares following the first anniversary of the listing of the Ordinary Shares on Nasdaq (the “Listing Date”), the Investor may transfer all or any portion of its then-remaining rights under this Agreement to any transferee (each, a “transferee”); provided that, prior to the Listing Date, the Investor may only transfer its rights under this Agreement to any transferee that is an Affiliate of the Investor. Any transfer of registration rights pursuant to this Section 12 shall be effective upon receipt by the Company of (x) written notice from the Investor stating the name and address of any transferee and identifying the amount of Registrable Ordinary Shares with respect to which the rights under this Agreement are being transferred and the nature of the rights so transferred and (y) a written agreement from the transferee to be bound by all of the terms of this Agreement. In connection with any such transfer, the term “Investor” as used in this Agreement shall, where appropriate to assign such rights to such transferee, be deemed to refer to the transferee holder of such Registrable Ordinary Shares. The Investor and such transferees may exercise the registration rights hereunder in such proportion (not to exceed the then-remaining rights hereunder) as they shall agree among themselves.

(b) After such transfer, the Investor shall retain its rights under this Agreement with respect to all other Registrable Ordinary Shares owned by the Investor. Upon the request of the Investor, the Company shall execute a Registration Rights Agreement with such transferee or a proposed transferee substantially similar to the applicable sections of this Agreement.

If the Investor offers Registrable Ordinary Shares by forward sale, or any options, rights, warrants or other securities issued by it, the Company or any other person that are offered with, convertible into or exercisable or exchangeable for any Registrable Ordinary Shares, the Registrable Ordinary Shares subject to such forward sale or underlying such options, rights, warrants or other securities shall be eligible for registration pursuant to Sections 2, 3 and 4 of this Agreement.

Exhibit A

PLAN OF DISTRIBUTION

The Company is registering the shares of common stock covered by this prospectus for the selling Investor. As used in this prospectus, “selling Investor” includes the donees, transferees, pledgees or others who may later hold the selling Investor’s interests. Pursuant to a registration rights agreement, dated as of June 24, 2020, the Company agreed to register the common stock owned by the selling Investor and to indemnify the selling Investor against certain liabilities related to the selling of the common stock, including liabilities arising under the Securities Act. Under the registration rights agreement, the Company also agreed to pay the costs and fees of registering the shares of common stock; however, the selling Investor will pay any brokerage commissions or underwriting discounts relating to the sale of the shares of common stock.

The selling Investor may sell the common stock being offered hereby in one or more of the following ways at various times:

The selling shareholder may offer its shares of common stock in one or more offerings pursuant to one or more prospectus supplements, if required by applicable law, and any such prospectus supplement will set forth the terms of the relevant offering to the extent required. To the extent the shares of common stock offered pursuant to a prospectus supplement remain unsold, the selling shareholder may offer those shares of common stock on different terms pursuant to another prospectus supplement.

The selling Investor will act independently of the Company in making decisions with respect to the timing, manner and size of each sale. The selling Investor may sell the common stock on the [national securities exchange] or otherwise, at market prices prevailing at the time of sale, at prices related to the prevailing market prices, or at negotiated prices. If underwriters are used in the sale, the common stock will be acquired by the underwriters for their own account and may be resold at various times in one or more transactions, including negotiated transactions, at a fixed public offering price or prices, which may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices, or at negotiated prices. A distribution of the common stock by the selling Investor may also be effected through the issuance by the selling Investor or others of derivative securities, including without limitation, warrants, exchangeable securities, forward delivery contracts and the writing of options.

In addition, the selling Investor may sell some or all of the shares of common stock covered by this prospectus through:

19

The selling Investor may also enter into hedging transactions. For example, the selling Investor may:

In addition, the selling Investor may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement. If so, the third party may use securities borrowed from the selling Investor or others to settle such sales and may use securities received from the selling Investor to close out any related short positions. The selling Investor may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement.

The applicable prospectus supplement will set forth the terms of the offering of the common stock covered by this prospectus, including:

20

Any public offering price and any discounts, commissions, concessions or other items constituting compensation allowed or reallowed or paid to underwriters, dealers or agents may be changed from time to time.

The selling Investor may negotiate and pay broker-dealers’ commissions, discounts or concessions for their services. Broker-dealers engaged by the selling Investor may allow other broker-dealers to participate in resales. The selling Investor and any broker-dealers involved in the sale or resale of the common stock may qualify as “underwriters” within the meaning of Section 2(a)(11) of the Securities Act. In addition, the broker-dealers’ commissions, discounts or concessions may qualify as underwriters’ compensation under the Securities Act. If the selling Investor qualifies as an “underwriter,” it will be subject to the prospectus delivery requirements of Section of the Securities Act.

In addition to selling its common stock under this prospectus, the selling Investor may:
