5. Registration Rights.

(a) The Company agrees that, within thirty (30) days after the Closing Date it will file a shelf registration statement with the Commission to register the resale of the Acquired Shares under the Securities Act and the rules and regulations promulgated thereunder and applicable state securities law (the “Registration Statement”), and the Company shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) sixty (60) days after the Closing Date (or ninety (90) days after the Closing Date if the Commission notifies the Company that it will “review” the Registration Statement) and (ii) the third (3rd) business day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Date”). The Company agrees to cause such Registration Statement, or another shelf registration statement that includes the Acquired Shares to be sold pursuant to this Subscription Agreement, to remain effective until the earliest of (i) the third anniversary of the Closing, (ii) the date on which the Subscriber ceases to hold any Acquired Shares issued pursuant to this Subscription Agreement, or (iii) the first date on which the Subscriber is able to sell all of its Acquired Shares issued pursuant to this Subscription Agreement (or shares received in exchange therefor) under Rule 144 without volume or manner of sale restrictions (the earliest of (i)-(iii) being the “Expiration”). The Subscriber agrees to disclose its ownership to the Company upon request to assist it in making the determination described above. The Company may amend the Registration Statement so as to convert the Registration Statement to a Registration Statement on Form S-3 at such time after the Company becomes eligible to use such From S-3. The Company may delay filing or suspend the use of any such registration statement if it determines, after consultation with counsel to the Company, that in order for the registration statement to not contain a material misstatement or omission, an amendment thereto would be needed, or if such filing or use could materially affect a bona fide business or financing transaction of the Company or would require premature disclosure of information that could materially adversely affect the Company (each, a “Suspension Event”); provided, that, (i) the Company may not delay or suspend the Registration Statement on more than two occasions or for more than sixty (60) consecutive calendar days, or more than one hundred twenty (120) total calendar days, in each case during any twelve-month period and (ii) the Company shall use commercially reasonable efforts to make such registration statement available for the sale by the undersigned of such securities as soon as practicable thereafter. Upon receipt of any written notice from the Company (which notice shall not contain any material non-public information regarding the Company) of the happening of any such Suspension Event during the period that the Registration Statement is effective or if as a result of such Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, Subscriber agrees that (i) it will immediately discontinue offers and sales under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Subscriber receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law or subpoena. If so directed by the Company, Subscriber will deliver to the Company or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the resale of securities in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Acquired Shares shall not apply (i) to the extent Subscriber is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up. The Company’s obligations to include the Acquired Shares issued pursuant to this Subscription Agreement (or shares issued in exchange therefor) for resale in the Registration Statement are contingent upon the Subscriber furnishing in writing to the Company such information regarding the Subscriber, the securities of the Company held by the Subscriber and the intended method of disposition of such Acquired Shares, which shall be limited to non-underwritten public offerings, as shall be reasonably requested by the Company to effect the registration of such Acquired Shares, and shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations, provided, however, that the Subscriber shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Acquired Shares.

| -8- |

(b) The Company shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless each Subscriber (to the extent a seller under the Registration Statement), the officers, directors, employees and agents of each of them, and each person who controls such Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the fullest extent permitted by applicable law, from and against any and all out-of-pocket losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or (ii) any violation or alleged violation by the Company of the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 5, except to the extent that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding such Subscriber furnished to the Company by such Subscriber expressly for use therein or such Subscriber has omitted a material fact from such information or otherwise violated the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder; provided, however, that the indemnification contained in this Section 5(c) shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld, conditioned or delayed), nor shall the Company be liable for any Losses to the extent they arise out of or are based upon a violation which occurs (A) in reliance upon and in conformity with information furnished by a Subscriber, (B) in connection with any failure of such person to deliver or cause to be delivered a prospectus made available by the Company in a timely manner, or (C) as a result of offers or sales effected by or on behalf of any person by means of a freewriting prospectus (as defined in Rule 405) that was not authorized in writing by the Company. The Company shall notify such Subscriber promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 5 of which the Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Acquired Shares by such Subscriber.

(c) Each Subscriber shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents 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), to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent that such untrue statements or omissions are based upon information regarding such Subscriber furnished to the Company by such Subscriber for use therein; provided, however, that the indemnification contained in this Section 5(d) shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of such Subscriber (which consent shall not be unreasonably withheld, conditioned or delayed). In no event shall the liability of any Subscriber be greater in amount than the dollar amount of the net proceeds received by such Subscriber upon the sale of the Acquired Shares giving rise to such indemnification obligation. Each Subscriber shall notify the Company promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 5(d) of which such Subscriber is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Acquired Shares by such Subscriber.

6. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to occur of (a) such date and time as the Transaction Agreement is terminated in accordance with its terms, (b) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, (c) if any of the conditions to Closing set forth in Section 3 of this Subscription Agreement are not satisfied on or prior to the Closing and, as a result thereof, the transactions contemplated by this Subscription Agreement are not or will not be consummated at the Closing, or (d) if the Closing has not occurred on or before February 11, 2021; provided that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach. The Company shall notify the undersigned of the termination of the Transaction Agreement promptly after the termination of such agreement.

7. Trust Account Waiver. Notwithstanding anything else in this Subscription Agreement, the Subscriber acknowledges that he has read the prospectus dated February 6, 2019 (the “Prospectus”) and understands that Monocle has established a trust account (the “Trust Account”) for the benefit of the stockholders of Monocle (the “Monocle Stockholders”) and that Monocle may disburse monies from the Trust Account only (a) to Monocle in limited amounts from time to time in order to permit Monocle to pay its operating expenses, (b) if Monocle completes the transactions which constitute its initial business combination, then to those persons and in such amounts as described in the Prospectus, and (c) if Monocle fails to complete its initial business combination within the allotted time period and liquidates to Monocle in limited amounts to permit Monocle to pay the costs and expenses of its liquidation and dissolution, and then to the Monocle Stockholders. All liabilities and obligations of Monocle due and owing or incurred at or prior to the closing of its initial business combination shall be paid as and when due, including all amounts payable (x) to the Monocle Stockholders in the event they elect to have their shares redeemed in accordance with Monocle’s certificate of incorporation (the “Monocle Charter”) and/or the liquidation of Monocle, (y) to Monocle after, or concurrently with, the consummation of its initial business combination, and (z) to Monocle in limited amounts for its operating expenses and tax obligations incurred in the ordinary course of business consistent with past practice. Subscriber further acknowledge that, if the transactions contemplated by the Transaction Agreement (or, upon termination of the Transaction Agreement, another business combination) are not consummated by February 11, 2021, or such date as determined by amending the Monocle Charter, Monocle will be obligated to return to the Monocle Stockholders the amounts being held in the Trust Account, unless such date is otherwise extended. Upon the Transaction Closing, Monocle shall cause the Trust Account to be disbursed to the Company and as otherwise contemplated by the Transaction Agreement. Accordingly, the Subscriber, for himself and his representatives, advisors and all other associates and affiliates (each a “Subscriber Related Party”), hereby waive all rights, title, interest or claim of any kind to collect from the Trust Account any monies that may be owed to them by Monocle or the Company for any reason whatsoever arising out of this Subscription Agreement, including for a breach of this Subscription Agreement by Monocle or the Company or any negotiations, agreements or understandings with Monocle or the Company (whether in the past, present or future) in connection with this Subscription Agreement (each a “Claim”), and will not seek recourse against the Trust Account in connection with such Claims at any time for any reason whatsoever; provided, that (i) nothing herein shall serve to limit or prohibit a Subscriber Related Party’s right to pursue a Claim against Monocle or the Company for legal relief against assets held outside the Trust Account, for specific performance or other equitable relief, and (ii) nothing herein shall serve to limit or prohibit any Claims that a Subscriber Related Party may have in the future against Monocle or the Company’s assets or funds that are not held in the Trust Account (including any funds that have been released from the Trust Account and any assets that have been purchased or acquired with any such funds), or otherwise by virtue of such Subscriber Related Party’s record or beneficial ownership of securities of the Company acquired by any means other than pursuant to this Subscription Agreement, including, but not limited to, any redemption right with respect to any such securities of the Company. This paragraph will survive the termination of this Subscription Agreement for any reason.
