The form of Warrant need not be changed because of any adjustment pursuant to this Section 6, and Warrant[s] issued after such adjustment may state the same Warrant Price and the same number of shares of Common Stock as is stated in the Warrant[s] initially issued pursuant to this Agreement; provided, however, that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

[Notwithstanding the foregoing, no assignment, transfer, pledge or disposal of any portion of a Warrant to an Affiliate of the Warrantholders shall relieve Warrantholder from any of its obligations hereunder and the Warrantholder shall cause its Affiliates receiving any portion of a Warrant to comply with the terms of this Agreement applicable to such Warrant, including, without limitation, the transfer restrictions set forth in this Section 7. Upon receipt of reasonable advance notice of a transfer to an Affiliate of the Warrantholder, the Company shall reissue and register such Warrants in the name of such Affiliate of the Warrantholder and take all other actions reasonably necessary to give effect to such transfer. Upon such transfer, such Affiliate of the Warrantholder receiving such Warrants shall have all the rights of the Warrantholder relating to such Warrants under this Agreement.]

8.2 Date Fixed for, and Notice of, Redemption. In the event that the Company elects to redeem all of the Warrant[s] pursuant to Section 8.1, the Company shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed [in place of the foregoing, certain Warrant Agreements included the following: e-mailed by the Company to the Warrantholder at [•], with a copy sent] by first class mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (such period, the “Redemption Period”) to the Warrantholder in accordance with Section 10.3. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Warrantholder received such notice.

8.3 Exercise After Notice of Redemption. The Warrant[s] may be exercised, for cash (or on a “cashless basis” in accordance with [Section 5.3.1(b)]⁷⁷ of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section 8.2 hereof and prior to the Redemption Date. In the event that the Company determines to require the Warrantholder to exercise the Warrant[s] on a “cashless basis” pursuant to [Section 5.3.1(b)]⁷⁸, the notice of redemption shall contain the information necessary to calculate the number of shares of Common Stock to be received upon exercise of the Warrant[s], including the “Fair Market Value” (as such term is defined in [Section 5.3.1(b)]⁷⁹ hereof) in such case. On and after the Redemption Date, the record holder of the Warrant[s] shall have no further rights except to receive, upon surrender of the Warrant[s], the Redemption Price.]

8. ⁸⁰Other Provisions Relating to Rights of [Holder[s] of Warrant[s]]⁸¹.

8.1 No Rights as Stockholder. [The]⁸² Warrant does not entitle [the]⁸³ Warrantholder to any of the rights of a stockholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of the Company or any other matter.

8.2 Lost, Stolen, Mutilated, or Destroyed Warrant[s]. If any Warrant is lost, stolen, mutilated, or destroyed, the Company [may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof)]⁸⁴ issue a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.

[Certain Warrant Agreements included the following:

8.4 Cashless Exercise [at Company’s Option]. [If the Warrants are held by the Warrantholder or any of its Affiliates, the Warrantholder may exercise Warrants on a “cashless basis” by surrendering the Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (i) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the excess of the Fair Market Value over the Warrant Price by (ii) the Fair Market Value. Solely for purposes of this Section 8.4, the “Fair Market Value” shall mean the average closing price of the Common Stock for the ten (10) trading days ending on the trading day prior to the date on which the notice of exercise of the Warrants is sent to the Company.] If the Common Stock is at the time of any exercise of [the]⁸⁵ Warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act (or any successor rule), the Company may, at its option, require the holder[s] of the Warrant[s] who exercise [the] Warrant[s] to exercise [the]⁸⁶ Warrant[s] on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act (or any successor rule).]

8.4 Registration Rights.

(a) The [Warrantholder[s]]⁸⁷ agree[s] that, as soon as practicable, but in no event later than thirty (30) calendar days after the first day of the Exercise Period of a Warrant (each, a “Filing Date”), the Company will file with the U.S. Securities and Exchange Commission (the “Commission”) (at the Company’s sole cost and expense) a registration statement registering the resale of the Warrant Shares issuable upon exercise of such Warrant (each, a “Registration Statement”), and the Company shall use its commercially reasonable efforts to cause such Registration Statement to be declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the ninetieth (90th) calendar day (if the Commission notifies the Company that it will “review” such Registration Statement) following the first day of the Exercise Period of such Warrant and (ii) the tenth (10th) Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that such Registration Statement will not be “reviewed” or will not be subject to further review (each, an “Effectiveness Date”); provided, however, that if the Commission is closed for operations due to a government shutdown, the applicable Effectiveness Date shall be extended by the same amount of days that the Commission remains closed for operations; provided, further, that the Company’s obligations to include the applicable Warrant Shares in the Registration Statement are contingent upon the Warrantholder[s] furnishing in writing to the Company such information regarding the Warrantholder[s], the securities of the Company held by the Warrantholder[s], the intended method of disposition of the applicable Warrant Shares (which shall be limited to non-underwritten public offerings) and such other information as shall be reasonably requested by the Company to effect the registration of such Warrant Shares, and the Warrantholder[s] 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, including providing that the Company shall be entitled to postpone and suspend the effectiveness or use of any Registration Statement during any customary blackout or similar period or as permitted hereunder. Any failure by the Company to file a Registration Statement by the applicable Filing Date or to effect such Registration Statement by the

applicable Effectiveness Date shall not otherwise relieve the Company of its obligations to file or effect the applicable Registration Statement as set forth above in this [Section 9.5[(a)]]⁸⁸. [Upon the request of the Warrantholder[s],] the Company will provide a draft of each Registration Statement to the Warrantholder[s] at least two (2) Business Days in advance of filing such Registration Statement[, and will reasonably promptly advise the Warrantholders when such Registration Statement has been declared effective by the Commission]. In no event shall the Warrantholder[s] be identified as a statutory underwriter in a Registration Statement unless requested by the Commission; provided, however, that, if the Commission requests that the Warrantholder[s] be identified as a statutory underwriter in a Registration Statement, the Warrantholder[s] will have an opportunity to withdraw the applicable Warrant Shares from such Registration Statement. Notwithstanding the foregoing, if the Commission prevents the Company from including any or all of the Warrant Shares proposed to be registered under a Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the applicable Warrant Shares by the Warrantholder[s] or otherwise, such Registration Statement shall register for resale such number of Warrant Shares which is equal to the maximum number of Warrant Shares as is permitted by the Commission. In such event, the number of shares of Common Stock to be registered for the Warrantholder[s] or other holders of shares of Common Stock named in such Registration Statement shall be reduced pro rata among all such holders. In the event the Company amends a Registration Statement in accordance with the foregoing, the Company will use its commercially reasonable efforts to promptly file with the Commission one or more registration statements to register the resale of those Registrable Securities that were not registered on such initial Registration Statement, as so amended[, and to cause such amendment or Registration Statement to become effective as promptly as reasonably practicable]. The Company will[, at its own expense,] use its commercially reasonable efforts to maintain the continuous effectiveness of each Registration Statement until all applicable securities cease to be Registrable Securities or such shorter period upon which each holder of Registrable Securities included in such Registration Statement have notified the Company that such Registrable Securities have actually been sold. The Company will provide all customary and commercially reasonable cooperation necessary to (i) enable the Warrantholder[s] to resell the applicable Warrant Shares pursuant to the applicable Registration Statement or Rule 144, as applicable, (ii) qualify the applicable Warrant Shares for listing on the primary stock exchange on which the [Company’s] Common Stock [are]⁸⁹ then listed, (iii) update or amend each Registration Statement as necessary to include applicable Registrable Securities and (iv) provide customary notice to holders of Registrable Securities. “Registrable Securities” shall mean, as of any date of determination, with respect to a Registration Statement, the Warrant Shares and any other equity security of the Company issued or issuable with respect to the Warrant Shares registered for resale under such Registration Statement by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event or otherwise. As to any particular Registrable Securities, once issued, such securities shall cease to be Registrable Securities with respect to a Registration Statement at the earliest of: (A) when the Warrantholder[s] cease[s] to hold any Registrable Securities registered for resale under such Registration Statement; (B) the date all Registrable Securities held by the Warrantholder[s] registered for resale under such Registration Statement may be sold without restriction under Rule 144, including, without limitation, any volume and manner of sale restrictions which may be applicable to Affiliates under Rule 144, and without the requirement for the Company to be in compliance with the current public information required under Rule 144, (C) when such securities shall have ceased to be outstanding or (D) [three (3) years from the date of effectiveness of the applicable Registration Statement] [in the place of the foregoing, certain Warrant Agreements included the following: two years following the expiration of the applicable Exercise Period].

(b) In the case of the registration, qualification, exemption or compliance effected by the Company pursuant to this Agreement, the Company shall, upon reasonable request, inform the Warrantholder[s] as to the status of such registration, qualification, exemption and compliance. At its expense the Company shall:

(i) except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which the Company determines to obtain, continuously effective with respect to the Warrantholder[s], and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, for as long as the Warrantholder[s] continue[s] to hold applicable Registrable Securities;

(ii) advise the Warrantholder[s], as promptly as practicable but in any event, within three (3) Business Days:

(1) when a Registration Statement or any amendment thereto has been filed with the Commission and when such Registration Statement or any post-effective amendment thereto has become effective;

(2) after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(3) of the receipt by the Company of any notification with respect to the suspension of the qualification of any Warrant Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; [and]

(4) subject to the provisions in this Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus included therein so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (and in the case of a prospectus, in the light of the circumstances under which they were made) not misleading[; and]

[(5)] Notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising the Warrantholder[s] of such events, provide the Warrantholder[s] with any material, nonpublic information regarding the Company other than to the extent that providing notice to the Warrantholder[s] of the occurrence of the events listed in (1) through (4) above may constitute material, nonpublic information regarding the Company;

(iii) use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iv) upon the occurrence of any event contemplated in [Section 9.5(b)(ii)(4)]⁹⁰, except for such times as the Company is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Company shall use its commercially reasonable efforts to, as soon as reasonably practicable, prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Warrant Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(v) use its commercially reasonable efforts to cause all applicable Warrant Shares to be listed on the primary securities exchange or market, if any, on which the Common Stock [issued by the Company have been]⁹¹ listed;

(vi) allow the Warrantholder[s] to review [and consent to (which consent shall not be unreasonably withheld, conditioned or delayed)] disclosure specifically regarding the Warrantholder[s] in any Registration Statement on reasonable advance notice [(at least two (2) Business Days in advance of filing such Registration Statement)]; and

(vii) use its commercially reasonable efforts to take all other steps reasonably necessary to effect the registration of the Warrant Shares pursuant to this [Section 9.5]⁹².

(c) Notwithstanding anything to the contrary in this Agreement, the Company shall be entitled to delay the filing or postpone the effectiveness of any Registration Statement, and from time to time to require the Warrantholder[s] not to sell under any Registration Statement or to suspend the effectiveness thereof, if it determines (1) that in order for a Registration Statement not to contain a material misstatement or omission, (x) an amendment thereto would be needed to include information that would at that time not otherwise be required in a current, quarterly, or annual report under the Exchange Act, (y) the negotiation or consummation of a transaction by the Company or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event, the Company’s board of directors reasonably believes would require additional disclosure by the Company in such Registration Statement of material information that the Company has a bona fide business purpose or legal obligations for keeping confidential and the non-disclosure of which in such Registration Statement would be expected, in the reasonable determination of the Company’s board of directors, to cause such Registration Statement to fail to comply with applicable disclosure requirements, or (z) in the good faith judgment of the majority of the members of the Company’s board of directors, [upon the advice of legal counsel,] such filing or effectiveness or use of such Registration Statement, would be seriously detrimental to the Company and the majority of the members of the Company’s board of directors concludes as a result that it is essential to defer such filing, or (2) to delay the filing or initial effectiveness of, or suspend use of, a Registration Statement and such delay or suspension arises out of, or is a result of, or is related to or is in connection with [any order, directive, guideline, comment or recommendation from the Commission or the Company’s auditor or accountant that is

applicable to the Company]⁹³ or other changes to the financial statements related to accounting matters with respect to securities issued in, or other matters related to, the Company’s initial public offering (each such circumstance, a “Suspension Event”); provided, however, that the Company may not delay or suspend a Registration Statement on more than two (2) occasions or for more than sixty (60) consecutive calendar days, or more than ninety (90) total calendar days, in each case during any twelve (12)-month period. Upon receipt of any written notice from the Company of the happening of any Suspension Event during the period that a Registration Statement is effective or if as a result of a Suspension Event a 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, the Warrantholder[s] agree[s] that (i) it will immediately discontinue offers and sales of the applicable Warrant Shares under such Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the Warrantholder[s] receive[s] 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, the Warrantholder[s] will deliver to the Company or, in the Warrantholder[s]’[s] sole discretion destroy, all copies of the prospectus covering the applicable Warrant Shares in the Warrantholder[s]’[s] possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the applicable Warrant Shares shall not apply (i) to the extent the Warrantholder[s] [is]⁹⁴ 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.

(d) The Warrantholder[s] may deliver written notice (an “Opt-Out Notice”) to the Company requesting that the Warrantholder[s] not receive notices from the Company otherwise required by this [Section 9.5]⁹⁵; provided, however, that the Warrantholder[s] may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from the Warrantholder[s] (unless subsequently revoked), (i) the Company shall not deliver any such notices to the Warrantholder[s] and the Warrantholder[s] shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to the Warrantholder[s]’[s] intended use of an effective Registration Statement, the Warrantholder[s] will notify the Company in writing at least two (2) Business Days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or would have been delivered but for the provisions of this [Section 9.5(d)]⁹⁶) and the related suspension period remains in effect, the Company will so notify the Warrantholder[s], within one (1) Business Day of the Warrantholder[s]’[s] notification to the Company, by delivering to the Warrantholder[s] a copy of such previous notice of Suspension Event, and thereafter will provide the Warrantholder[s] with the related notice of the conclusion of such Suspension Event promptly following its availability.

[(e) Indemnification.

(i) The Company shall, notwithstanding the termination of this Agreement, indemnify and hold harmless, to the extent permitted by law, [the] Warrantholder[s], [its]⁹⁷ directors, officers, employees, Affiliates, agents, and each Person who controls [the] Warrantholder[s] (within the meaning of Section 15 of the Securities Act [or the Exchange Act]) and the officers, directors and employees of each such controlling Person from and against any and all losses, claims, damages, liabilities, costs and expenses (including, without limitation, any reasonable and documented attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) (collectively, “Losses”) that arise out of, are based upon, or are caused by any [actual or alleged] untrue statement of material fact contained in any Registration Statement (or incorporated by reference therein), prospectus included in any Registration Statement [(“Prospectus”)] or preliminary [Prospectus]⁹⁸ or any amendment thereof or supplement thereto or document incorporated by reference therein or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein in light of the circumstances under which they were made, not misleading, except to the extent that such untrue statements, omissions or alleged omissions are caused by or contained in any information furnished in writing to the Company by or on behalf of such Warrantholder expressly for use therein. The Company shall notify Warrantholder[s] [in writing] promptly of the institution, threat or assertion (to the Company’s knowledge) of any proceeding arising from or in connection with the Registration Statement; provided, however, that the indemnification contained in this Section 9.5(e)[(i)] 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 connection with any failure of such Person to deliver or cause to be delivered a [Prospectus]⁹⁹ made available by the Company in a timely manner or (B) in connection with any offers or sales effected by or on behalf of Warrantholder[s] in violation of this Agreement.

(ii) In connection with any Registration Statement in which [the] Warrantholder[s] [is]¹⁰⁰ participating, Warrantholder[s] agree[s][, severally and not jointly with any other holder of Common Shares that is a party to any other subscription agreement,] to indemnify and hold harmless, to the extent permitted by law, the Company, its directors, officers, agents, employees and Affiliates and each Person or entity who controls the Company (within the meaning of Section 15 of the Securities Act) and the officers, directors and employees of each such controlling Person against any Losses, resulting from, arising out or that are based upon any [actual or alleged] untrue statement of material fact contained in the Registration Statement, [Prospectus]¹⁰¹ or preliminary [Prospectus]¹⁰² or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required

to be stated therein or necessary to make the statements therein in light of the circumstances under which they were made, not misleading, but only to the extent that such untrue statement or omission was made (or not [contained]¹⁰³ in the case of an omission) in reliance on, and in conformity with, any information or affidavit so furnished in writing by or on behalf of Warrantholder[s] expressly for use therein; provided, however, that in no event shall the liability of Warrantholder[s] be greater in amount than the dollar amount of the net proceeds received by Warrantholder[s] from the sale of Warrant Shares pursuant to such Registration Statement giving rise to such indemnification obligation and provided further that the indemnification contained in this [Section 9.5(e)]¹⁰⁴ shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of Warrantholder[s] (which consent shall not be unreasonably withheld, conditioned or delayed).

(iii) Any Person entitled to indemnification [under this Section 9.5(e)]¹⁰⁵ shall (1) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (2) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent. An indemnifying party who elects not to assume the defense of a claim shall not be obligated to pay the [reasonable and documented] fees and expenses of more than one counsel (together with one firm of local counsel (in each jurisdiction)) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the written consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(iv) The indemnification provided under this [Section 9.5(e)]¹⁰⁶ shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, employee, agent, Affiliate or controlling Person of such indemnified party and shall survive the transfer of the Warrant Shares.

(v) If the indemnification provided under this [Section 9.5(e)]¹⁰⁷ from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any Losses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party,

as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by (or not supplied by, in the case of an omission), such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in [this] [Section 9.5(e)]¹⁰⁸, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 9.5(e)(v) from any Person who was not guilty of such fraudulent misrepresentation. [Certain Warrant Agreements included the following: Any contribution pursuant to this Section 8(e)(v) by any seller of Warrant Shares shall be limited in amount to the amount of net proceeds received by such seller from the sale of such Warrant Shares pursuant to the Registration Statement.]]

(f) The Company will use its commercially reasonable efforts to (A) at the reasonable request of the Warrantholders, deliver all the necessary documentation to cause the transfer agent to the Company to remove all restrictive legends from any Registrable Securities being sold under the Registration Statement or pursuant to Rule 144 at the time of sale of such Registrable Securities, or that may be sold by the Warrantholders without restriction under Rule 144, including without limitation, any volume, information and manner of sale restrictions, and (B) deliver or cause its legal counsel to deliver to the transfer agent to the Company the necessary legal opinions or instruction letters required by the transfer agent to the Company, if any, in connection with the instruction under clause (A), in each case in the case of clauses (A) and (B), upon the receipt of the Warrantholders’ representation letters and such other customary supporting documentation as requested by (and in a form reasonably acceptable to) the Company and its counsel. The Warrantholders agree to disclose their respective beneficial ownership, as determined in accordance with Rule 13d-3 of the Exchange Act, of Registrable Securities to the Company (or its successor) upon reasonable request to assist the Company in making the determination described above.]
