Glazer further agrees that it will not request redemption of any of the Shares (including any Additional Shares) in conjunction with GigCapital’s stockholders’ approval of the Business Combination. For purposes hereof, “Short Sales” include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Securities and Exchange Act of 1934 (the “Exchange Act”), whether or not against the box, and all types of direct and indirect stock pledges, forward sales contracts, options, puts, calls, short sales, swaps, “put equivalent positions” (as defined in Rule 16a-1(h) under the Exchange Act) and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers.

b. Option to Purchase Additional Shares. GigCapital hereby acknowledges that nothing in this Agreement shall prohibit Glazer from purchasing prior to the Business Combination Closing Date up to an additional 77,067 shares of common stock of GigCapital (the “Additional Shares”). Glazer’s Additional Shares shall be purchased by the Company in accordance with Section 1.

c. Open Market Sale. Notwithstanding anything to the contrary herein, the parties agree that Glazer shall, commencing on the day after the Business Combination Closing Date, have the right but not the obligation to sell any or all of its Shares (including any Additional Shares) in the open market if the sale price exceeds $10.50 per Share prior to payment of any commissions due by Glazer for such sale. Glazer shall give written notice to the Company of any sale of Shares (including any Additional Shares) within three (3) Business Days following the date of such sale, and such notice shall include the date of the sale, the number of Shares sold, and confirmation that the sale price per Share was greater than $10.50 per Share prior to the payment of any commissions due by Glazer for the sale.

d. Right to Purchase Warrants. Nothing in this Agreement shall prohibit Glazer from entering into a contract to purchase and/or sell or purchasing or selling GigCapital warrants.

e. Escrow. Simultaneously with the closing of the Business Combination, the Company shall deposit into an escrow account (the “Escrow”) with Continental Stock Transfer & Trust Company (the “Escrow Agent”), subject to the terms of a written escrow agreement (the “Escrow Agreement”) dated as of the date hereof in the form attached as Exhibit A hereto, an amount equal to $10,680,000 (or such lesser amount as is equal to $10.68 multiplied by the number of Shares and

4

Additional Shares held by Glazer at the Business Combination Closing Date). Concurrently with the execution of the Escrow Agreement, the Company shall provide irrevocable written instructions to wire the Share Purchase Price to the Escrow at the closing of the Business Combination. The payments to be made by the Company to Glazer in accordance with Section 1 will be made with funds from the Escrow. In the event that Glazer sells any Shares (including any Additional Shares) as provided in Section 4.c., it shall provide notice to the Company within three (3) Business Days of such sale, and Glazer shall issue instructions to the Escrow Agent to release from the Escrow for Company’s use without restriction an amount equal to the number of Shares (including any Additional Shares) sold multiplied by $10.68. In the event that Glazer elects not to sell to the Company any Shares by delivering a Share Retention Notice pursuant to Section 1.a., Glazer shall issue instructions to the Escrow Agent to release from the Escrow the remaining funds held in the Escrow for the purchase of such Shares for the Company’s use without restriction.

f. Letter of Credit. Notwithstanding Section 4.e., the Company shall use its best efforts to enter into a letter of credit agreement (the “Letter of Credit Agreement”) for the issuance of a standby letter of credit (the “Letter of Credit”) for the benefit of Glazer with Bank of America or another letter of credit provider acceptable to Glazer (the “Issuing Bank”) as soon as practicable to replace the Escrow. If the Letter of Credit Agreement is entered into prior to or simultaneously with the closing of the Business Combination, in lieu of depositing funds into the Escrow pursuant to Section 4.e., the Company shall deposit into a collateral account (the “Collateral Account”) with the Issuing Bank an amount equal to $10,680,000 (or such lesser amount as is equal to $10.68 multiplied by the number of Shares and Additional Shares held by Glazer at the Business Combination Closing Date), for purposes of securing the full and final payment and performance of the Company’s obligations under the Letter of Credit Agreement. If the Letter of Credit Agreement is entered into after the Business Combination, Glazer shall issue instructions to the Escrow Agent to deposit the funds held in Escrow into the Collateral Account with the Issuing Bank for purposes of securing the full and final payment and performance of the Company’s obligations under the Letter of Credit Agreement. Concurrently with the execution of the Letter of Credit Agreement, the Issuing Bank shall issue the Letter of Credit for the benefit of Glazer in the amount of $10,680,000 (or such lesser amount as is equal to $10.68 multiplied by the number of Shares and Additional Shares held by Glazer at the Business Combination Closing Date). Glazer shall drawdown from the Letter of Credit to satisfy the payment due to Glazer pursuant to Section 1. In the event that Glazer sells any Shares (including any Additional Shares) as provided in Section 4.c., it shall provide notice to the Company and the Issuing Bank within three (3) Business Days of such sale, and the Issuing Bank shall release from the Collateral Account an amount equal to the number of Shares (including any Additional Shares) sold multiplied by $10.68 to the Company for the Company’s use without restriction, with a corresponding reduction in the amount of the Letter of Credit. In the event that Glazer elects not to sell to the Company any Shares pursuant to Section 1.a., Glazer shall deliver a Share Retention Notice to the Company and the Issuing Bank, and the Issuing Bank shall release all funds in the Collateral Account to the Company for the Company’s use without restriction and terminate the Letter of Credit.

g. Notification. The Company shall notify Glazer of the occurrence of any event that would make any of the representations and warranties of GigCapital set forth in Section 3 untrue or incorrect at any time between the date of this Agreement and the Shares Closing Date, except where the failure of a representation and warranty to be true and correct would not have a material adverse effect on GigCapital or the Company’s ability to consummate the transactions contemplated by this Agreement.

h. Most Favored Nation. GigCapital will not to enter into an agreement (binding or otherwise) with any other holder of shares of common stock of GigCapital (including, but not limited to, an affiliate of Nomura Securities International, Inc. and Yakira Capital Management, Inc.) to grant more favorable rights to such holder of shares regarding such holder’s ability to offer, sell,

5

contract to sell, pledge, transfer, assign, or otherwise dispose of, directly or indirectly, or hedge shares of common stock of GigCapital (including engaging in any transactions involving any derivative securities of the Company and any Short Sales involving any of GigCapital and the Company’s securities), until the Shares Closing Date, than those agreed to between GigCapital and Glazer in this Agreement. If GigCapital does enter into such an agreement as described in the previous sentence, it will immediately notify Glazer and offer the same terms to Glazer.

i. Security Agreement in Escrow Account. To secure the obligations of GigCapital and the Company under this Agreement, GigCapital and the Company grant to Glazer a security interest in all right, title, and interest of GigCapital and the Company in and to the Escrow, the Escrow Agreement, all rights related thereto, and all proceeds, products, and profits of the foregoing. In the event of a default by GigCapital or the Company under this Agreement, then, in addition to any other rights Glazer may have under this Agreement, the Escrow Agreement, and applicable law, Glazer shall also have the rights and remedies of a secured party under the Uniform Commercial Code as enacted in the State of New York. GigCapital and the Company authorize Glazer to file such UCC financing statements or other documents with respect to its security interest as Glazer may deem appropriate in its discretion.
