The Firm Shares and the Option Shares (to the extent the aforementioned option is exercised) are herein collectively called the “Shares”.

In consideration of the mutual agreements contained herein and of the interests of the parties in the transactions contemplated hereby, the parties hereto agree as follows:

1. Representations and Warranties of the Company.

The Company represents and warrants to each of the Underwriters as follows:

(a) The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (File No. 333-253139) covering the public offering and sale of certain securities (the “Shelf Securities”) under the Securities Act of 1933, as amended (the “Act”), and the rules and regulations (the “Rules and Regulations”) of the Commission thereunder, including the Shares, to be issued from time to time by the Company or sold by any selling stockholders, which automatic shelf registration statement became effective under Rule 462(e) under the Rules and Regulations. The registration statement as amended to the date of this equity underwriting agreement (this “Agreement”), including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430B under the Act, is hereinafter referred to as the “Registration Statement”, and the related prospectus covering the Shelf Securities dated February 16, 2021 in the form first used to confirm sales of the Shares (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Act) is hereinafter referred to as the “Basic Prospectus.” The Basic Prospectus, as supplemented by the prospectus supplement specifically relating to the Shares in the form first used to confirm sales of the Shares (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Act) is hereinafter referred to as the “Prospectus,” and the term “Preliminary Prospectus” means any preliminary form of the Prospectus.

(b) As of the Applicable Time (as defined below) and as of the Closing Date or the Option Closing Date, as the case may be, neither (i) the General Use Free Writing Prospectus (as defined below) issued at or prior to the Applicable Time, the Statutory Prospectus (as defined below) and the information included on Schedule II hereto, all considered together (collectively, the “General Disclosure Package”), nor (ii) any individual Limited Use Free Writing Prospectus (as defined below), when considered together with the General Disclosure Package, included or will include any untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to information contained in or omitted from any Issuer Free Writing Prospectus, in reliance upon, and in conformity with, written information furnished to the Company by or on behalf of any Underwriter through the Representatives, specifically for use therein, it being understood and agreed that the only such information is that described in Section 14 hereof.

(h) If the General Disclosure Package is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event or development shall occur or condition shall exist as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement the General Disclosure Package in order to make the statements therein, in the light of the circumstances, not misleading, or to make the statements therein not conflict with the information contained in the Registration Statement then on file, or if it is necessary at any time to amend or supplement the General Disclosure Package to comply with any law, the Company promptly will prepare, file with the Commission (if required) and furnish to the Underwriters and any dealers an appropriate amendment or supplement to the General Disclosure Package.

(i) The Company will make generally available to its security holders, as soon as it is practicable to do so, but in any event not later than 15 months after the date hereof, an earnings statement (which need not be audited) in reasonable detail, covering a period of at least 12 consecutive months beginning after the date hereof, which earnings statement shall satisfy the requirements of Section 11(a) of the Act and Rule 158 under the Act and will advise you in writing when such statement has been so made available, which requirements may be satisfied by filing on the Commission’s Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”).

(m) The Company shall apply the net proceeds of its sale of the Shares as set forth in the Registration Statement, the General Disclosure Package and the Prospectus and shall file with the Commission such information as may be required by Rule 463 under the Act.

(n) The Company shall not invest, or otherwise use the proceeds received by the Company from its sale of the Shares in such a manner as would require the Company or any of the Subsidiaries to register as an investment company under the 1940 Act.

(o) The Company will maintain a transfer agent and, if necessary under the jurisdiction of incorporation of the Company, a registrar for the Common Stock.

(p) The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

7. Costs and Expenses.

Except as otherwise provided in this Agreement, the Company and MegaChips will pay, on the pro rata basis set forth below, all costs, expenses and fees incident to the performance of the obligations of the Sellers under this Agreement, including, without limiting the generality of the foregoing, the following: (i) accounting fees of the Company; (ii) the fees and disbursements of counsel for the Company; (iii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriters, including any transfer or other taxes payable thereon; (iv) any roadshow expenses; provided, however, that, in connection with meetings with prospective purchasers and any roadshow undertaken in connection with the marketing of the Shares, (A) the Company and the Underwriters will each bear 50% of the costs associated with any chartered aircraft used, and (B) the Company and the Underwriters will each pay their own lodging and other costs associated with the roadshow; (v) the cost of printing and delivering to, or as requested by, the Underwriters copies of the Registration Statement, Preliminary Prospectuses, the Issuer Free Writing Prospectuses, the Prospectus, this Agreement, the listing application, any Blue Sky survey, in each case, any supplements or amendments thereto; (vi) the filing fees of the Commission; (vii) the filing fees and expenses (including reasonable and documented legal fees and disbursements) incident to securing any required review by FINRA of the terms of the sale of the Shares; (viii) all expenses and application fees related to the listing of the Shares on of the Exchange; (ix) the cost of printing certificates, if any, representing the Shares; (x) the costs and charges of any transfer agent, registrar or depositary; and (xi) the expenses, including the reasonable and documented fees and disbursements of counsel for the Underwriters, incurred in connection with the qualification of the Shares under foreign or state securities or Blue Sky laws and the preparation, printing and distribution of a Blue Sky memorandum (including the related fees and expenses of counsel for the Underwriters); provided, however, that the aggregate amount of legal fees and disbursements of counsel for the Underwriters incurred pursuant to subclauses (vii) and (xi) shall not exceed $15,000. Neither the Company nor the Selling Stockholder shall, however, be required to pay for any of the Underwriters’ expenses (other than those related to qualification under FINRA regulation and state securities or Blue Sky laws) except that, if this Agreement shall not be consummated because the conditions in Section 8 hereof are not satisfied, or because this Agreement is terminated by the Representatives pursuant to Section 12 hereof, or by reason of any failure, refusal or inability on the part of the Company or the Selling Stockholder to perform any undertaking or satisfy any condition of this Agreement or to comply with any of the terms hereof on their part to be performed,

-21-

unless such failure, refusal or inability is due primarily to the default or omission of any Underwriter, the Company and the Selling Stockholder shall reimburse the several Underwriters, on the pro rata basis set forth below, for reasonable out-of-pocket expenses, including reasonable and documented fees and disbursements of counsel, reasonably incurred in connection with investigating, marketing and proposing to market the Shares or in contemplation of performing their obligations hereunder; but the Company and the Selling Stockholder shall not in any event be liable to any of the several Underwriters for damages on account of loss of anticipated profits from the sale by them of the Shares. Except as otherwise provided in this Agreement, the Company will pay the costs and expenses (including without limitation any damages or other amounts payable in connection with legal or contractual liability) associated with the reforming of any contracts for sale of the Shares made by the Underwriters caused by a breach of the representation in Section 1(b) hereof) (the “Company Fees”). Notwithstanding anything to the contrary in this Agreement, the Selling Stockholder shall be solely responsible for payment of all costs, expenses, fees, and disbursements of counsel to the Selling Stockholder and all underwriting discounts and commissions in connection with the sale of shares by the Selling Stockholder pursuant to this Agreement (the “Selling Stockholder Sale Expenses”), and the Company shall be solely responsible for payment of all underwriting discounts and commissions in connection with the sale of shares by the Company pursuant to this Agreement (the “Company Sale Expenses”).

Except as set forth above with respect to the Selling Stockholder Sale Expenses, the Company Sale Expenses and the Company Fees, each of the Company and the Selling Stockholder shall be responsible for its respective pro rata portion of the costs, expenses, and fees set forth above, including those incurred by the Company, in connection with the transactions contemplated by this Agreement (collectively, the “Transaction Expenses”), based on the number of shares sold by the Selling Stockholder and the Company, respectively, on the Closing Date (which, for the avoidance of doubt, includes any Option Shares sold on the Closing Date). Notwithstanding anything to the contrary in this Agreement: (i) the Selling Stockholder, and the Company agree to inform the Underwriters prior to the Closing Date the amount of the Selling Stockholder’s pro rata portion of the Transaction Expenses, which amount shall have been mutually agreed upon by the Selling Stockholder and the Company (the “Selling Stockholder Pro Rata Expenses”), and (ii) the Selling Stockholder Pro Rata Expenses shall be deducted from the proceeds otherwise payable to the Selling Stockholder pursuant to the transactions contemplated by this Agreement and shall be transmitted by the Underwriters, along with the proceeds payable to the Company pursuant to the transactions contemplated by this Agreement, on the Closing Date via federal (same day) funds to an account designated by the Company. Notwithstanding anything to the contrary in this Agreement, if the Company sells any Option Shares after the Closing Date, (x) the Company shall be solely responsible for any additional costs, expenses, and fees incurred by the Company in connection with the sale of such Option Shares, and (y) the Selling Stockholder Pro Rata Expenses shall not be increased.

(g) The Representatives shall have received on the Closing Date a certificate of the Selling Stockholder to the effect that, as of the Closing Date:

(h) On or prior to the date hereof, the Selling Stockholder shall have furnished for review by the Representatives executed copies of the Power of Attorney and Custody Agreement.

(j) The Firm Shares and Option Shares, if any, have been duly listed, subject to notice of issuance, on the Exchange.

(k) The Lockup Agreements and Selling Stockholder Lockup Agreement described in Sections 5(l) and 6(a) hereof are in full force and effect.

-25-

9. Indemnification.

(a) The Company agrees:

(i) to indemnify and hold harmless each Underwriter, the directors and officers of each Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, with respect to the Registration Statement or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or with respect to any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto (including any information deemed to be part thereof pursuant to Rule 430B), the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus, or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 14 hereof; and

(ii) to reimburse each Underwriter, each Underwriters’ directors and officers, and each such controlling person upon demand for any legal or other out-of-pocket expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares, whether or not such Underwriter or controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriters were not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriters will promptly return all sums that had been advanced pursuant hereto.

(b) The Selling Stockholder agrees to indemnify the Underwriters, each Underwriters’ directors and officers and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which such Underwriter or controlling person may become subject under the Act or otherwise to the same extent as indemnity is provided by the Company pursuant to Section 9(a) hereof; provided, however, that such Selling Stockholder shall be liable only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, in reliance upon, and in conformity with the Selling Stockholder Information; and provided, further, that the aggregate liability of the Selling Stockholder pursuant to this subsection (b) shall be limited to an amount equal to the aggregate public offering price, less underwriting discounts and commissions

-26-

(but before payment of expenses), of the Firm Shares sold by the Selling Stockholder under this Agreement (the “Selling Stockholder Proceeds”). This indemnity obligation will be in addition to any liability which the Company may otherwise have.

(c) Each Underwriter severally and not jointly will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the Registration Statement, the Selling Stockholder and each person, if any, who controls the Company or the Selling Stockholder within the meaning of the Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer, Selling Stockholder or controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, with respect to the Registration Statement or any amendment or supplement thereto (including any information deemed to be part thereof pursuant to Rule 430B), the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or with respect to any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, Selling Stockholder or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 14 hereof. This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have.

(d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 9, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 9(a) or (b) hereof shall be available to any party who shall fail to give notice as provided in this Section 9(d) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 9(a) or (b) hereof. In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified

-27-

party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action. Such firm shall be designated in writing by you in the case of parties indemnified pursuant to either Section 9(a) or Section 9(b) hereof and by the Company and the Selling Stockholder in the case of parties indemnified pursuant to Section 9(c) hereof. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(e) To the extent the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under Section 9(a), (b) or (c) hereof in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Stockholder on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault 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 Company or the Selling Stockholder on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) The Company, the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 9(f) were determined by pro rata allocation

-28-

(even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 9(f). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 9(f) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.
