Not later than the Registration Filing Date, the Company shall file with the Commission a Registration Statement on Form S -1, or any other similar long-form registration, relating to the resale by the Holders of all of the Registrable Securities, and the Company shall use its best efforts to cause such Registration Statement to be declared effective prior to the Registration Default Date. Notwithstanding the foregoing, in the event the Company signs a letter of intent or comparable agreement with an underwriter(s) which contemplates an Initial Public Offering (the “IPO Engagement”), then the Company shall have the right to extend the Registration Filing Date to the earlier of (i) such date that is acceptable to such underwriter(s); provided that such date may be no later than six months following the effective date of the Registration Statement filed in connection with such IPO Engagement, or (ii) 45 days from effective date of any termination or abandonment of such IPO Engagement.

(b) Piggyback Registration. Following the Initial Public Offering, if the Company shall determine to register for sale for cash any of its Common Stock, for its own account or for the account of others (other than the Holders), other than (i) the Initial Public Offering, (ii) a registration relating solely to employee benefit plans or securities issued or issuable to employees, consultants (to the extent the securities owned or to be owned by such consultants could be registered on Form S-8) or any of their Family Members (including a registration on Form S-8) or (iii) a registration relating to a Securities Act Rule 145 transaction or a registration on Form S-4 in connection with a merger, acquisition, divestiture, reorganization or similar event, the Company shall promptly give to the Holders written notice thereof (and in no event shall such notice be given less than twenty (20) calendar days prior to the public filing of such registration statement (the “Piggyback Registration Statement”)), and shall, subject to Section 3(c), include as a Piggyback Registration all of the Registrable Securities specified in a written request delivered by the Holder thereof within ten (10) calendar days after receipt of such written notice from the Company. However, the Company may, without the consent of the Holders, withdraw such Piggyback Registration Statement prior to its becoming effective if the Company or such other stockholders have elected to abandon the proposal to register the securities proposed to be registered thereby.

(c) Underwriting. If a Piggyback Registration is for a registered public offering that is to be made by an underwriting other than an IPO Engagement, the Company shall so advise the Holders of the Registrable Securities eligible for inclusion in such Registration Statement pursuant to Sections 3(b). In that event, the right of any Holder to Piggyback Registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to sell any of their Registrable Securities through such underwriting shall (together with the Company and any other stockholders of the Company selling their securities through such underwriting) enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting by the Company or the selling stockholders, as applicable. Notwithstanding any other provision of this Section 3, if the managing underwriter(s) or the Company determines that marketing factors require a limitation on the number of shares of Common Stock or the amount of other securities to be underwritten, the managing underwriter(s), at its sole discretion, may exclude some or all Registrable Securities from such registration and underwriting. The Company shall so advise all Holders (except those Holders who failed to timely elect to include their Registrable Securities through such underwriting or have indicated to the Company their decision not to do so), and indicate to each such Holder the number of shares of Registrable Securities that may be included in the registration and underwriting, if any. The number of shares of Registrable Securities to be included in such registration and underwriting shall be allocated among such Holders as follows:

(i) If the Piggyback Registration was initiated by the Company, the number of shares that may be included in the registration and underwriting shall be allocated first to the Company and then, subject to obligations and commitments existing as of the date hereof, to all selling stockholders, including the Holders, who have requested to sell in the registration on a pro rata basis according to the number of shares requested to be included therein; or

(ii) If the Piggyback Registration was initiated by the exercise of demand registration rights by a stockholder or stockholders of the Company (other than the Holders), then the number of shares that may be included in the registration and underwriting shall be allocated first to such selling stockholders who exercised such demand and then, subject to obligations and commitments existing as of the date hereof, to all other selling stockholders, including the Holders, who have requested to sell in the registration on a pro rata basis according to the number of shares requested to be included therein.

No Registrable Securities excluded from the underwriting by reason of the managing underwriter’s marketing limitation shall be included in such registration and no liquidated damages as set forth in Section 3(d) shall accrue with respect to such excluded securities. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw such Holder’s Registrable Securities therefrom by delivering a written notice to the Company and the managing underwriter(s). The Registrable Securities so withdrawn from such underwriting shall also be withdrawn from such registration; provided, however, that, if by the withdrawal of such Registrable Securities, a greater number of Registrable Securities held by other Holders may be included in such registration (up to the maximum of any limitation imposed by the managing underwriter(s)), then the Company shall offer to all Holders who have included Registrable Securities in the registration the right to include additional Registrable Securities pursuant to the terms and limitations set forth herein in the same proportion used above in determining the underwriter limitation.

(d) Liquidated Damages Following a Registration Event. If a Registration Event occurs, then the Company will make payments to each Holder of Registrable Securities (each, a “Qualified Purchaser”), as liquidated damages for the amount of damages to the Qualified Purchaser by reason thereof, at a rate equal to 0.50% of the purchase price per Unit paid by such Qualified Purchaser in the 2018 PPO for the Registrable Securities then held by such Qualified Purchaser for each full period of 30 days of the Registration Default Period (which shall be pro-rated for any period less than 30 days). Notwithstanding the foregoing, the maximum amount of liquidated damages that may be paid to any Qualified Purchaser pursuant to this Section 3(d) shall be an amount equal to 6% of the aggregate purchase price paid by such Qualified Purchaser in the 2018 PPO for the Registrable Securities held by such Qualified Purchaser at the time of the first occurrence of a Registration Event. Each such payment shall be due and payable within five Business Days after the end of each full 30-day period of the Registration Default Period until the termination of the Registration Default Period and within five (5) Business Days after such termination. Such payments shall constitute the Qualified Purchaser’s exclusive remedy for any damages resulting from a Registration Event. If the Company fails to pay any partial liquidated damages pursuant to this Section 3(d) in full within seven (7) Business Days after the date payable, the Company will pay interest thereon at a rate of 5% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the Qualified Purchaser, accruing daily from the date such partial liquidated damages are due until such amounts, plus all such interest thereon, are paid in full. The Registration Default Period shall terminate upon the earlier of (i) the filing of the Registration Statement (if the Registration Event was triggered by clause (a) of the definition thereof), (ii) the SEC Effective Date (if the Registration Event was triggered by clause (b) of the definition thereof), (iii) the ability of the Qualified Purchaser to effect sales pursuant to the Registration Statement (if the Registration Event was triggered by clause (c) of the definition thereof and not excused pursuant to Section 3(e)), and (iv) the listing or inclusion and/or trading of the Common Stock on an Approved Market, as the case may be (if the Registration Event was triggered by clause (d) of the definition thereof). The amounts payable as liquidated damages pursuant to this Section 3(d) shall be payable in lawful money of the United States.

(e) Notwithstanding the provisions of Section 3(d) above:

(1)(a) if the Commission does not declare the Registration Statement effective on or before the Registration Default Date, or (b) if the Commission allows the Registration Statement to be declared effective at any time before or after the Registration Default Date, subject to the withdrawal of certain Registrable Securities from the Registration Statement, and the reason for (a) or (b) is the Commission’s determination that (x) the offering of any of the Registrable Securities constitutes a primary offering of securities by the Company, (y) Rule 415 may not be relied upon for the registration of the resale of any or all of the Registrable Securities, and/or (z) a Holder of any Registrable Securities must be named as an underwriter, the Holders understand and agree that in the case of (b) the Company may reduce, on a pro rata basis, the total number of Registrable Securities to be registered on behalf of each such Holder, and, in the case of (a) or (b), that a Holder shall not be entitled to any liquidated damages under Section 3(d) with respect to the Registrable Securities not registered for the reason set forth in (a), or so reduced on a pro rata basis as set forth in (b). In any such pro rata reduction, the number of Registrable Securities to be registered on such Registration Statement will be reduced (i) first, by the Registrable Securities represented by the Registrable Warrant Shares (applied, in the case that some Registrable Warrant Shares may be registered, to the Holders on a pro rata basis based on the total number of unregistered Registrable Warrant Shares held by such Holders on a fully diluted basis), and (ii) second, by the Registrable Securities represented by Investor Shares (applied, in the case that some Investor Shares may be registered, to the Holders on a pro rata basis based on the total number of unregistered Investor Shares). In addition, any such affected Holder shall be entitled to Piggyback Registration rights after the Registration Statement is declared effective by the Commission until such time as: (AA) all Registrable Securities have been registered pursuant to an effective Registration Statement, (BB) the Registrable Securities may be resold without restriction pursuant to SEC Rule 144 of the Securities Act or (CC) the Holder agrees to be named as an underwriter in any such registration statement. The Holders acknowledge and agree the provisions of this paragraph may apply to more than one Registration Statement; and

(2) For not more than thirty (30) consecutive days or for a total of not more than sixty (60) days in any twelve (12) month period, the Company may suspend the use of any prospectus included in any Registration Statement contemplated by this Section in the event that the Company determines in good faith that such suspension is necessary to (A) delay the disclosure of MNPI concerning the Company, the disclosure of which at the time is not, in the good faith opinion of the Company, in the best interests of the Company or (B) amend or supplement the affected Registration Statement or the related prospectus so that (i) such Registration Statement shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein or (ii) such prospectus shall not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading, including in connection with the filing of a post-effective amendment to such Registration Statement in connection with the Company’s filing of an Annual Report on Form 10-K for any fiscal year (an “Allowed Delay”); provided, that the Company shall promptly (a) notify each Holder in writing of the commencement of an Allowed Delay, but shall not (without the prior written consent of an Holder) disclose to such Holder any MNPI giving rise to an Allowed Delay, (b) advise the Holders in writing to cease all sales under the Registration Statement until the end of the Allowed Delay and (c) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable.

In the event of an Allowed Delay, the liquidated damages set forth in Section 3(d) shall not accrue during such Allowed Delay.

(f) Holdback Agreements. (A) Subject to paragraphs (B), (C) and (D) below, from and after the SEC Effective Date, each Holder understands that (i) it shall not sell, offer, pledge, contract to sell, grant any option or contract to purchase, purchase any option or contract to sell, grant any right or warrant to purchase, lend or otherwise transfer or encumber, directly or indirectly, any shares of the Registrable Securities, nor shall such Holder enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any shares of the Registrable Securities (any of the foregoing under (i), a “Transfer”) until the Release Date (as defined below); provided, however, that such Holder shall be permitted to Transfer up to 50% of such Holder’s Registrable Securities held by it at any time on or after the SEC Effective Date, and (ii) following the Release Date, it shall be entitled to Transfer all remaining Registrable Securities held by such Holder. Each Holder hereby covenants and agrees that (x) it shall abide by the restrictions set forth above and (y) the Company shall be entitled to place “stop transfer” instructions with the Company’s transfer agent in compliance with the above restrictions. For purposes of this clause (f), the term “Release Date” shall mean the date that is 90 days after the SEC Effective Date; provided, that in the event the Company delivers a notice of redemption to the Holders of the Investor Warrants (pursuant to the terms of such warrants) (the “Redemption Notice”), the restrictions set forth above shall terminate effective on the date of delivery of the Redemption Notice.

(B) Notwithstanding Section 3(f)(A) above, but subject to paragraph (C) below, in the event the Closing Price is $10.00 or above (as adjusted for any stock split, share dividends, share combinations, or the like) for 20 consecutive trading days, all Registrable Securities shall be released from the holdback agreements of paragraph (A) above. The “Closing Price” means, for any date, the closing price per share of the Common Stock for such date (or the nearest preceding date) on the primary eligible market or exchange on which the Common Stock is then listed or quoted.

In furtherance of the foregoing, the Holder agrees, upon request of the Company, to enter into a lock-up agreement consistent with the foregoing as may be required by any underwriter engaged by the Company in connection with such IPO Engagement.

(D) Notwithstanding anything to the contrary, Section 3(f) shall not apply to Transfers to Permitted Assignees.

(E) Subject to the Company’s other obligations in this Agreement, the Company shall have the right to terminate or withdraw any registration initiated by it under Section 3(b) whether or not any Holder has elected to include securities in such registration. The expenses of such withdrawn registration shall be borne by the Company in accordance with Section 6.

(f) notify each Holder of Registrable Securities, the disposition of which requires delivery of a prospectus relating thereto under the Securities Act, of the happening of any event (as promptly as practicable after becoming aware of such event), which comes to the Company’s attention, that will after the occurrence of such event cause the prospectus included in such Registration Statement, if not amended or supplemented, to contain an untrue statement of a material fact or an omission 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, and the Company shall promptly thereafter prepare and furnish to such Holder a supplement or amendment to such prospectus (or prepare and file appropriate reports under the Exchange Act) so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, unless suspension of the use of such prospectus otherwise is authorized herein or in the event of a Blackout Period, in which case no supplement or amendment need be furnished (or Exchange Act filing made) until the termination of such suspension or Blackout Period;

(l) during the Effectiveness Period, refrain from bidding for or purchasing any Common Stock or any right to purchase Common Stock or attempting to induce any person to purchase any such security or right if such bid, purchase or attempt would in any way limit the right of the Holders to sell Registrable Securities by reason of the limitations set forth in Regulation M of the Exchange Act; and

(m) take all other reasonable actions necessary to expedite and facilitate the disposition by the Holders of the Registrable Securities pursuant to the Registration Statement.

5. Suspension of Offers and Sales.

6. Registration Expenses. The Company shall pay all expenses in connection with any registration obligation provided herein, including, without limitation, all registration, filing, stock exchange fees, printing expenses, all fees and expenses of complying with applicable securities laws, and the fees and disbursements of counsel for the Company and of its independent accountants; provided, that, in any registration, each party shall pay for its own underwriting discounts and commissions and transfer taxes. Except as provided in this Section 6 and Section 9, the Company shall not be responsible for the expenses of any attorney or other advisor employed by a Holder.

7. Assignment of Rights. No Holder may assign its rights under this Agreement to any party without the prior written consent of the Company; provided, however, that any Holder may assign its rights under this Agreement without such consent to a Permitted Assignee as long as (a) such transfer or assignment is effected in accordance with applicable securities laws; (b) such transferee or assignee agrees in writing to become subject to the terms of this Agreement; and (c) such Holder notifies the Company in writing of such transfer or assignment, stating the name and address of the transferee or assignee and identifying the Registrable Securities with respect to which such rights are being transferred or assigned.

8. Information by Holder. A Holder with Registrable Securities included in any registration shall furnish to the Company (and any managing underwriter(s), where applicable) such information regarding itself, the Registrable Securities held by it, the intended method of disposition of such securities, and such other information as shall be required in order to comply with any applicable law or regulation in connection with the registration of such Holder’s Registrable Securities or any qualification or compliance with respect to such Holder’s Registrable Securities and referred to in this Agreement. A form of Selling Stockholder Questionnaire is attached as Exhibit A hereto for such purposes.

9. Indemnification.

(a) In the event of the offer and sale of Registrable Securities under the Securities Act, the Company shall, and hereby does, indemnify and hold harmless, to the fullest extent permitted by law, each Holder, its directors, officers, partners, each other person who participates as an underwriter in the offering or sale of such securities, and each other person, if any, who controls or is under common control with such Holder or any such underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several, and expenses to which the Holder or any such director, officer, partner or underwriter or controlling person may become subject under the Securities Act, the Exchange Act, or any other federal or state law, insofar as such losses, claims, damages, liabilities or expenses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (1), in the case of any registration statement prepared and filed by the Company under which Registrable Securities were registered under the Securities Act, if such registration statement contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (2) in the case of any preliminary prospectus, final prospectus or summary prospectus contained in such registration statement, or any amendment or supplement thereto, if such preliminary prospectus, final prospectus or summary prospectus includes an untrue statement of a material fact or omits to state a material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading, or any violation or alleged violation of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law in connection with this Agreement; and the Company shall reimburse the Holder, and each such director, officer, partner, underwriter and controlling person for any legal or any other expenses reasonably incurred by them in connection with investigating, defending or settling any such loss, claim, damage, liability, action or proceeding; provided, that such indemnity agreement found in this Section 9(a) shall in no event exceed the net proceeds from the 2018 PPO received by the Company; and provided further, that the Company shall not be liable in any such case (i) to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement in or omission from such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Company by the Holder specifically for use in the preparation thereof or (ii) if the person asserting any such loss, claim, damage, liability (or action or proceeding in respect thereof) who purchased the Registrable Securities that are the subject thereof did not receive a copy of the preliminary prospectus or the final prospectus (or the final prospectus as amended or supplemented) at or prior to the written confirmation of the sale of such Registrable Securities to such person because of the failure of such Holder or underwriter to so provide such preliminary or final prospectus and the untrue statement or omission of a material fact made in such preliminary prospectus was corrected in the amended preliminary or final prospectus (or the final prospectus as amended or supplemented). Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Holders, or any such director, officer, partner, underwriter or controlling person and shall survive the transfer of such shares by the Holder.

(b) As a condition to including Registrable Securities in any registration statement filed pursuant to this Agreement, each Holder agrees to be bound by the terms of this Section 9 and to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and officers, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which the Company or any such director or officer or controlling person may become subject under the Securities Act, the Exchange Act, or any other federal or state law, to the extent arising out of or based solely upon: (x) such Holder’s failure to comply with the prospectus delivery requirements of the Securities Act or (y)(1), in the case of any registration statement prepared and filed by the Company under which Registrable Securities were registered under the Securities Act, if such registration statement contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (2) in the case of any preliminary prospectus, final prospectus or summary prospectus contained in such registration statement, or any amendment or supplement thereto, such preliminary prospectus, final prospectus or summary prospectus includes an untrue statement of a material fact or omits to state a material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading, (i) to the extent, but only to the extent, that such untrue statement or omission referred to in (y)(1) or (y)(2) above is contained in any information so furnished in writing by such Holder to the Company specifically for inclusion in the registration statement or such prospectus or (ii) to the extent that (1) such untrue statements or omissions referred to in (y)(1) or (y)(2) above are based solely upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in the Registration Statement, such prospectus or such form of prospectus or in any amendment or supplement thereto or (2) in the case of an occurrence of an event of the type specified in Section 4(f) hereof, the use by such Holder of an outdated or defective prospectus after the Company has notified such Holder in writing that the prospectus is outdated or defective and prior to the receipt by such Holder of the advice contemplated in Section 4(f). Each Holder’s obligation to indemnify shall be individual, not joint and several, and in no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c) Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in this Section (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the indemnifying party of the commencement of such action; provided, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Section, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, the indemnifying party shall be entitled to participate in and to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof, unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties arises in respect of such claim after the assumption of the defenses thereof or the indemnifying party fails to defend such claim in a diligent manner. If, in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties arises in respect of such claim after the assumption of the defenses thereof, the indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the reasonable fees and expenses to be paid by the indemnifying party. No indemnifying party shall be liable for any settlement of any action or proceeding effected without its consent. No indemnifying party shall, without the consent of the indemnified party (which consent shall not be unreasonably withheld, conditioned or delayed), consent to entry of any judgment or enter into any settlement, unless such consent to entry of judgment or settlement includes as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. Notwithstanding anything to the contrary set forth herein, and without limiting any of the rights set forth above, in any event any party shall have the right to retain, at its own expense, counsel with respect to the defense of a claim.

(d) If an indemnifying party does or is not permitted to assume the defense of an action pursuant to Sections 9(c) or in the case of the expense reimbursement obligation set forth in Sections 9(a) and (b), the indemnification required by Sections 9(a) and 9(b) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills received or expenses, losses, damages, or liabilities are incurred provided that the indemnifying party is provided appropriate documentation.

(e) If the indemnification provided for in Section 9(a) or 9(b) is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall (i) contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense as is appropriate to reflect the proportionate relative fault of the indemnifying party on the one hand and the indemnified party on the other (determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission relates to information supplied by the indemnifying party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission), or (ii) if the allocation provided by clause (i) above is not permitted by applicable law or provides a lesser sum to the indemnified party than the amount hereinafter calculated, not only the proportionate relative fault of the indemnifying party and the indemnified party, but also the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other, as well as any other relevant equitable considerations. No indemnified party guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any indemnifying party who was not guilty of such fraudulent misrepresentation.

(f) Other Indemnification. Indemnification similar to that specified in this Section (with appropriate modifications) shall be given by the Company and each Holder of Registrable Securities with respect to any required registration or other qualification of securities under any federal or state law or regulation or governmental authority other than the Securities Act, provided, however, to the extent the provisions included in an underwriting agreement entered in connection therewith are in conflict with any provisions in this Section, the provisions in the underwriting agreement shall control.

10. Rule 144. With a view to making available to the Holders the benefits of SEC Rule 144 and any other rule or regulation of the SEC that may at any time permit the Holders to sell the Registrable Securities to the public without registration, the Company agrees to use commercially reasonable efforts to: (i) to make and keep public information available as those terms are understood in SEC Rule 144, (ii) to file with the SEC in a timely manner all reports and other documents required to be filed by an issuer of securities registered under the Securities Act or the Exchange Act pursuant to SEC Rule 144, (iii) as long as any Holder owns any Registrable Securities, to furnish in writing upon such Holder’s request a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 and of the Securities Act and the Exchange Act, and to furnish to such Holder a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as may be reasonably requested in availing such Holder of any rule or regulation of the SEC permitting the selling of any such Registrable Securities without registration, (iv) with respect to the sale of any Registrable Securities by a Holder pursuant to SEC Rule 144 and subject to Holder providing necessary documentation to meet the requirements of such rule, to promptly furnish, without any charge to such Holder, a written legal opinion of its counsel to facilitate such sale and, if necessary, instruct its transfer agent in writing that it may rely on said written legal opinion of counsel with respect to said sale and (v) undertake any additional actions commercially necessary to maintain the availability of Rule 144.

11. Independent Nature of Each Purchaser’s Obligations and Rights. The obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser, and each Purchaser shall not be responsible in any way for the performance of the obligations of any other Purchaser under this Agreement. Nothing contained herein and no action taken by any Purchaser pursuant hereto, shall be deemed to constitute such Purchasers as a partnership, an association, a joint venture, or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

12. Miscellaneous.

(a) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the United States of America and the State of Delaware, both substantive and remedial, without regard to Delaware conflicts of law principles.

The foregoing consent to jurisdiction shall not be deemed to confer rights on any person other than the parties to this Agreement.

(b) Remedies. In the event of a breach by the Company or by a Holder of any of their respective obligations under this Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages (subject to the provisions of Section 3(d)), shall be entitled to specific performance of its rights under this Agreement. The Company and each Holder agree, except with respect to the provisions of Section 3(d), that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance in respect of such breach, it shall not assert or shall waive the defense that a remedy at law would be adequate.

(c) Successors and Assigns. Except as otherwise provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the successors, Permitted Assignees, executors and administrators of the parties hereto.

(d) No Inconsistent Agreements. The Company has not entered, as of the date hereof, and shall not enter, on or after the date of this Agreement, into any agreement with respect to its securities that would have the effect of impairing the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof.

Any waiver, permit, consent or approval of any kind or character on the part of any Holder of any breach or default under this Agreement, or any waiver on the part of any Holder of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing.

STOCKHOLDERS’ QUESTIONNAIRE

The following information is requested from you in connection with the preparation and filing by Hydrofarm Holdings Group, Inc. (the “Company”) of a Registration Statement on Form S-1 or other appropriate form (the “Registration Statement”) with the Securities and Exchange Commission (the “SEC”) for the registration and resale under the Securities Act of 1933, as amended (the “Securities Act”), of the Company’s common stock, including shares of common stock underlying certain Warrants (the “Registrable Securities”) acquired pursuant to a private placement by the Company.

Certain legal consequences arise from being named as a selling stockholder in the Registration Statement and the related prospectus. Accordingly, holders and beneficial owners of Registrable Securities are advised to consult their own securities law counsel regarding the consequences of being named or not being named as a selling stockholder in the Registration Statement and the related prospectus or supplements thereto.

We would appreciate your answering all of the questions included in this questionnaire, even though your answers may be in the negative, so that the Company will have a record of your responses for use in connection with the preparation of the Registration Statement. It is requested that you give careful attention to each question and that you complete this questionnaire personally.

In order to assist you in completing this questionnaire, certain terms used herein are defined in the appendix which is attached to this questionnaire. Each of such defined terms has been bolded and italicized for identification. The term “person,” as used in this questionnaire, means any natural person, company, government or political subdivision, agency or instrumentality of a government.

After you have completed the following questionnaire, please send the completed questionnaire by e-mail at _______________ or overnight courier as soon as possible to the attention of ______________.

SECURITIES HOLDINGS

Existing Holders:

Please fill in all blanks in the following questions related to your beneficial ownership of the Company’s common stock.

Generally, a beneficial owner of a security is a person who, directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise has or shares either:

(i) voting power, which includes the power to vote, or to direct the voting of such security; and/or

(ii) investment power, which includes the power to dispose, or to direct the disposition of, such security, even though he or she may not be the holder of record of the securities.

Thus, securities held in “street name” over which you exercise voting or investment power would be considered beneficially owned by you. Other examples of indirect ownership include ownership by a partnership in which you are a partner or by an estate or trust of which you or any member of your immediate family is a beneficiary. Ownership of securities held in the names of your spouse, minor children or other relatives who live in the same household may be attributed to you.

If you have any reason to believe that any interest in securities of the Company which you may have, however remote, is a beneficial interest, please describe such interest. For purposes of responding to this questionnaire, it is preferable to err on the side of inclusion rather than exclusion.

Where the SEC’s interpretation of beneficial ownership would require disclosure of your interest or possible interest in certain securities of the Company, and you believe that you do not actually possess the attributes of beneficial ownership, an appropriate response is to disclose the interest and at the same time disclaim beneficial ownership of the securities.

Please indicate the amount of common stock of the Company or any of its subsidiaries which you beneficially owned as of the date hereof.

Number of	Registered in	Beneficially	Shares to be	Remarks
Shares	the Name of	Owned by	Sold

For each holding:

•

State the nature of the holding (i.e., held in your own name, jointly, as a trustee or beneficiary of a trust, as a custodian, as an executor, in discretionary accounts, by your spouse or minor children, by a partnership of which you are a partner, etc.), and

•

State whether you are the beneficial owner by reason of (i) sole voting power, (ii) shared voting power, (iii) sole investment power, (iv) shared investment power, (v) the right to acquire stock within 60 days of the end of the calendar year, (vi) the right to acquire stock with the purpose of changing or influencing control; and/or (vii) a security-based swap that you hold that gives you voting or investment power over the underlying Company stock (even though you may not directly hold the underlying Company stock).

•

Indicate in the Remarks column below whether you have sole or shared voting or investment power with respect to any such securities, and in what capacity (i.e., individual, general partner, trustee) you have such power or powers.

•
