Exhibit 3.7

OPTION AGREEMENT

This Option Agreement (this “Agreement”) is made and entered as of this 16^th day of March, 2016, by and among James McCarthy and Richard Nathan (each, a “Grantor” and together, the “Grantors”) and Avon Road Partners, L.P. (the “Option Holder”). Reference is made to that certain Stockholders’ Agreement among KeyStone Solutions, Inc. (hereinafter “KSS”) and the Stockholders party thereto dated March 16, 2016 (the “Stockholders’ Agreement”). Capitalized terms used herein but not otherwise defined herein shall have the respective meanings ascribed to such terms in the Stockholders’ Agreement.

WHEREAS, the Option Holder desires to have the right to purchase from each Grantor the shares of Common Stock in KSS, in whole or in part, set forth opposite such Grantor’s name on Exhibit A attached hereto and made a part hereof (with respect to each Grantor, the “Option Shares”), and each Grantor desires to grant such right to the Option Holder, pursuant to the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing and the mutual and dependent covenants hereinafter set forth, and for other due and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties agree as follows:

1. Purchase Price. In consideration for the grant of the Option Right (as defined below), on the date hereof the Option Holder shall pay $10,000 to each Grantor (for a total of $20,000) in cash by wire transfer of immediately available funds (such payments, the “Option Right Payments”).

2. Grant of Option Right.

(a) Right to Purchase. Subject to the terms and conditions of this Agreement, including the payment of the Option Right Payments in accordance with Section 1, at any time and from time to time after the Effective Date and up to and including the second anniversary of such Effective Date (the “Option Termination Date”), the Option Holder and its permitted assignees shall have the right (the “Option Right”), but not the obligation, to cause each Grantor to sell some or all of such Grantor’s Option Shares to the Option Holder and/or its permitted assignees at the Purchase Price (as defined in Section 3 of this Agreement). The Option Right must be exercised simultaneously with respect to each Grantor on a pro rata basis based on the number of Option Shares to be sold by each Grantor as set forth on Exhibit A and must be exercised with respect to at least twenty-five percent (25%) of the Option Shares to be sold by such Grantor. After the Option Termination Date, the Option Right shall expire and shall no longer be valid or exercisable.

(b) Procedures. If the Option Holder and/or its permitted assignees desire to purchase the Option Shares, and subject to the full satisfaction of the condition precedent described in Section 2(c), the Option Holder and/or its permitted assignees shall, (i) on or before the Option Termination Date and on each occasion when the Option Holder and/or its permitted assignees desire to exercise the Option Right, deliver to each Grantor a written notice (the “Option

Exercise Notice”) exercising the Option Right and specifying the number of Option Shares to be purchased from each Grantor and, (ii) pay to each Grantor the Purchase Price in cash by check or wire transfer of immediately available funds applicable to the Option Shares to be purchased from each such Grantor, to be held in escrow by each such Grantor until each Grantor shall execute and deliver to the Option Holder and/or its permitted assignees a stock power transferring to the Option Holder and/or its permitted assignees the number of Option Shares purchased from such Grantor in such exercise, free and clear of all liens, claims, pledges, hypothecations or encumbrances (including all options, rights of first refusal and similar rights) (collectively, “Liens”) except (1) as may arise under applicable securities laws or under the Stockholders Agreement and (2) for liens, claims or encumbrances arising by virtue of any action or inaction by the Option Holder and/or its permitted assignees.

(c) Condition Precedent. The right of the Option Holder and/or its permitted assignees to exercise the Option Right shall become effective on the date KSS closes on the sale of Series A Preferred Stock resulting in gross proceeds to KSS in an amount determined by the Board of Directors of the Company (the “Effective Date”).

3. Purchase Price. In the event the Option Holder and/or its permitted assignees exercise the Option Right hereunder, the purchase price at which the Grantors shall be required to sell the Option Shares (the “Purchase Price”) shall be equal to $1.00 per Option Share.

4. Shares Subject to Stockholders Agreement. The Option Holder acknowledges that the Option Right and the Option Shares are in all respects subject to the terms, conditions and obligations set forth in the Stockholders Agreement.

5. Retention of Option Shares. Prior to the earlier of the exercise of the Option Right or the Option Termination Date, each Grantor agrees to retain the Option Shares held by such Grantor free and clear of all Liens and not to enter into any agreement restricting the transfer of such Grantor’s Option Shares except in each case as may arise under applicable securities laws and/or the Stockholders’ Agreement.

6. Notices. Any notice required or permitted by this Agreement shall be in writing and shall be deemed sufficient upon receipt, when delivered personally or by courier, overnight delivery service or confirmed facsimile, or 48 hours after being deposited in the U.S. mail as certified or registered mail with postage prepaid, if such notice is addressed to the party to be notified at such party’s address or facsimile number as set forth below or as subsequently modified by written notice.

Except as otherwise set forth in this Agreement, no failure to exercise, or delay in exercising, any rights, remedy, power or privilege arising from this Agreement shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

12. Severability. If any provision of this Agreement is held invalid or unenforceable, such decision shall not affect the validity or enforceability of any other provision of this Agreement, all of which other provisions shall remain in full force and effect.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

14. Jurisdiction and Venue. Each of the Option Holder and the Grantors irrevocably consents to the exclusive jurisdiction and venue of any court within Fairfax County, Virginia, in connection with any matter based upon or arising out of this Agreement or the matters contemplated herein, and agrees that process may be served upon them in any manner authorized by the laws of the Commonwealth of Virginia for such persons.
