e.“Registration Statement” means one or more registration statements of the Company covering only the resale of the Registrable Securities.

 

2.REGISTRATION.

 

a.Mandatory Registration.  The Company shall use reasonable best efforts to file with the SEC, within twenty (20) Business Days after the date hereof, an initial Registration Statement covering the maximum number of Registrable Securities as shall be permitted to be included thereon in accordance with applicable SEC rules, regulations and interpretations so as to permit the resale of such Registrable Securities by the Investor under Rule 415 under the Securities Act at then prevailing market prices (and not fixed prices), as mutually determined by both the Company and the Investor in consultation with their respective legal counsel, subject to the aggregate number of authorized shares of the Company’s Common Stock then available for issuance in its Certificate of Incorporation. The initial Registration Statement shall register only the Registrable Securities. The Investor and its counsel shall have a reasonable opportunity to review and comment upon such Registration Statement and any amendment or supplement to such Registration Statement and any related prospectus prior to its filing with the SEC, and the Company shall give due consideration to all such comments.  The Investor acknowledges that it will be identified in the initial Registration Statement as an underwriter within the meaning of Section 2(a)(11) of the Securities Act and shall furnish all information reasonably requested by the Company for inclusion therein. The Company shall use its reasonable best efforts to have the Registration Statement and any amendment declared effective by the SEC at the earliest possible date. The Company shall use reasonable best efforts to keep the Registration Statement effective pursuant to Rule 415 promulgated under the Securities Act and available for the resale by the Investor of all of the Registrable Securities covered thereby at all times until the date on which the Investor shall have resold all the Registrable Securities covered thereby and no Available Amount remains under the Purchase Agreement (the “Registration Period”). The Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any 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, in light of the circumstances in which they were made, not misleading.

 

b.Rule 424 Prospectus.  The Company shall, as required by applicable securities regulations, from time to time file with the SEC, pursuant to Rule 424 promulgated under the Securities Act, the prospectus and prospectus supplements, if any, to be used in connection with sales of the Registrable Securities under the Registration Statement.  The Investor and its counsel shall have a reasonable opportunity to review and comment upon such prospectus prior to its filing with the SEC, and the Company shall give due consideration to all such comments.  The Investor shall use its reasonable best efforts to comment upon such prospectus within one (1) Business Day from the date the Investor receives the final pre-filing version of such prospectus. 

 

c.Sufficient Number of Shares Registered.  In the event the number of shares available under the Registration Statement is insufficient to cover all of the Registrable Securities, the Company shall amend the Registration Statement or file a new Registration Statement (a “New Registration Statement”), so as to cover all of such Registrable Securities (subject to the limitations set forth in Section 2(a)) as soon as reasonably practicable, but in any event not later than ten (10) Business Days after the necessity therefor arises, subject to any limits that may be imposed by the SEC pursuant to Rule 415 under the Securities Act.  The Company shall use its reasonable best efforts to cause such amendment and/or New Registration Statement to become effective as soon as reasonably practicable following the filing thereof.

  d.           Offering.  If the staff of the SEC (the “Staff”) or the SEC seeks to characterize any offering pursuant to a Registration Statement filed pursuant to this Agreement as constituting an offering of securities that does not permit such Registration Statement to become effective and be used for resales by the Investor under Rule 415 at then-prevailing market prices (and not fixed prices), or if after the filing of the initial Registration Statement with the SEC pursuant to Section 2(a), the Company is otherwise required by the Staff or the SEC to reduce the number of Registrable Securities included in such initial Registration Statement, then the Company shall reduce the number of Registrable Securities to be included in such initial Registration Statement (with the prior consent, which shall not be unreasonably withheld, of the Investor and its legal counsel as to the specific Registrable Securities to be removed therefrom) until such time as the Staff and the SEC shall so permit such Registration Statement to become effective and be used as aforesaid.  In the event of any reduction in Registrable Securities pursuant to this paragraph, the Company shall file one or more New Registration Statements in accordance with Section 2(c) until such time as all Registrable Securities have been included in Registration Statements that have been declared effective and the prospectuses contained therein is available for use by the Investor.  Notwithstanding any provision herein or in the Purchase Agreement to the contrary, the Company’s obligations to register Registrable Securities (and any related conditions to the Investor’s obligations) shall be qualified as necessary to comport with any requirement of the SEC or the Staff as addressed in this Section 2(d).

k.The Company shall use its reasonable best efforts to cause the Registrable Securities covered by any Registration Statement to be registered with or approved by such other governmental agencies or authorities in the United States as may be necessary to consummate the disposition of such Registrable Securities.

 

l.On or before the date the Registration Statement is declared effective by the SEC, the Company shall issue to the Transfer Agent the Commencement Irrevocable Transfer Agent Instructions in the form attached hereto as Exhibit A, and on the date any Registration Statement which includes the Registrable Securities is ordered effective by the SEC, the Company shall deliver, and agrees to cause its legal counsel for the Company to deliver, to the Transfer Agent for such Registrable Securities (with copies to the Investor) confirmation that such registration statement has been declared effective by the SEC substantially in the form attached as an exhibit to the Commencement Irrevocable Transfer Agent Instructions.  Thereafter, if requested by the Buyer at any time, the Company agrees to cause its legal counsel to deliver to the Buyer a written confirmation whether or not the effectiveness of such Registration Statement has lapsed at any time for any reason (including, without limitation, the issuance of a stop order) and whether or not the Registration Statement is current and available to the Buyer for sale of all of the Registrable Securities.

 

m.The Company agrees to take all other reasonable actions as necessary and reasonably requested in writing by the Investor to expedite and facilitate disposition by the Investor of the  Registrable Securities pursuant to any Registration Statement.

Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Investor pursuant to Section 9.

7

 

 

 



 

connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution contained in Section 7 shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Investor, which consent shall not be unreasonably withheld, delayed or conditioned; provided, further, however, that the Investor shall be liable under this Section 6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net proceeds to the Investor as a result of the sale of Registrable Securities pursuant to such Registration Statement.  Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Investor pursuant to Section 9. 

 

c.Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the reasonable fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding.  The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or claim.  The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto.  No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its written consent, provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent.  No indemnifying party shall, without the consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified Person of a release from all liability in respect to such claim or litigation.  Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made.  The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

 

d.The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages are incurred.  Any Person receiving a payment pursuant to this Section 6 that is later determined not to be entitled to such payment shall return such payment to the person making it.

 

8

 

 

 



 

e.The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to applicable law.

 

7.CONTRIBUTION.

 

To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; provided, however, that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities.

 

8.REPORTS AND DISCLOSURE UNDER THE SECURITIES ACT.

 

With a view to making available to the Investor the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the SEC that may at any time permit the Investor to sell securities of the Company to the public without registration (“Rule 144”), the Company agrees, at the Company’s sole expense, to:

 

a.make and keep public information available, as those terms are understood and defined in Rule 144;

 

b.file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144;

 

c.furnish to the Investor so long as the Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company that it has complied with the reporting and or disclosure provisions of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Investor to sell such securities pursuant to Rule 144 without registration; and

 

d.take such additional action as is reasonably requested by the Investor to enable the Investor to sell the Registrable Securities pursuant to Rule 144, including, without limitation, delivering all such legal opinions, consents, certificates, resolutions and instructions to the Company’s Transfer Agent as may be reasonably requested from time to time by the Investor and otherwise fully cooperate with Investor and Investor’s broker to effect such sale of securities pursuant to Rule 144.

 

The Company agrees that damages may be an inadequate remedy for any breach of the terms and provisions of this Section 8 and that Investor shall, whether or not it is pursuing any remedies at law, be entitled to seek equitable relief in the form of a preliminary or permanent injunction, without having to post any bond or other security, upon any breach or threatened breach of any such terms or provisions.

In connection with the transactions contemplated by the Purchase Agreement, the Company has filed a registration statement on Form S-1 (File no. 333-[__________]) (the “Registration Statement”) (with the U.S. Securities & Exchange Commission (the “SEC”)) to register for resale under the Securities Act of 1933, as amended, the following shares of Common Stock:

We have delivered to you herewith a true and correct copy of resolutions adopted by the Company’s Board of Directors authorizing the issuances of Common Stock described herein.  No further consent or authorization is required by the Company, its Board of Directors or its stockholders in connection with the transactions contemplated by the Purchase Agreement. 

 

Promptly after the SEC declares effective the Registration Statement, the Company’s counsel shall deliver to you a notice that the Registration Statement has been declared effective by the SEC in the form of Exhibit I hereto (the “Notice of Effectiveness”).  Provided that the Company’s counsel has delivered to you the Notice of Effectiveness set forth in Exhibit I attached hereto, this letter shall serve as our irrevocable authorization and direction to:

 



 

 


	
 
	
(1)
	
remove any restricted stock transfer legend on the Commitment Shares and credit via the Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, 148,148 shares of Common Stock as Commitment Shares to the Investor’s balance account with DTC through its Deposit Withdrawal At Custodian (“DWAC”)




 

The information that shall be used for the transfer of shares is as follows:

Specifically, upon receipt by the Company of a copy of a Purchase Confirmation, the Company shall as soon as practicable, but in no event later than one (1) Business Day (as defined below) after receipt of such Purchase Confirmation, send, via facsimile, a copy of the Purchase Confirmation to you, which Purchase Confirmation shall constitute an irrevocable instruction to you to process such Purchase Confirmation in accordance with the terms of these instructions and the Purchase Confirmation.  Upon your receipt of a copy of the executed Purchase Confirmation, you shall use your best efforts to, within one (1) Business Day following the date of your receipt of the Purchase Confirmation, credit via the DTC Fast Automated Securities Transfer Program, upon the request of the Investor, such aggregate number of shares of Common Stock to which the Investor shall be entitled to the Investor’s balance account with DTC through its DWAC system for the number of shares of Common Stock to which the Investor shall be entitled as set forth in the Purchase Confirmation provided the Investor causes its bank or broker to initiate the DWAC transaction.  (“Business Day” shall mean any day on which the Company’s principle trading market is open for customary trading.) 

 

Provided that the Company’s counsel has delivered to you the Notice of Effectiveness set forth in Exhibit I attached hereto, the Company hereby confirms to you and the Investor that the Purchase Shares and the Commitment Shares shall not bear any legend restricting transfer of the Purchase Shares and Commitment Shares thereby and should not be subject to any stop-transfer restrictions and shall otherwise be freely transferable on the books and records of the Company; provided however, that if for any reason the Company is required to issue Purchase Shares and Commitment Shares which have not been registered under the Securities Act of 1933, as amended, then the certificates for such Purchase Shares and Commitment Shares shall bear the following legend and no other legend whatsoever:

The Company hereby confirms to you and the Investor that no instructions other than as contemplated herein will be given to you by the Company with respect to the Purchase Shares and the Commitment Shares.

 

Please be advised that the Investor is relying upon this letter as an inducement to purchase shares of Common Stock under the Purchase Agreement and, accordingly, the Investor is a party to the agreements set forth in this letter.

Pursuant to the Purchase Agreement, the Company also has entered into a Registration Rights Agreement, dated as of April 30, 2020, with the Investor (the “Registration Rights Agreement”) pursuant to which the Company agreed, among other things, to register with the U.S. Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Securities Act”)  the shares of Common Stock described below.

 

On [_______], 2020, the Company filed a Registration Statement (File No. 333-[_______]) (the “Registration Statement”) with the SEC to register for resale the following securities:

(2)
	
148,148 shares of Common Stock which have been issued to the Investor as a commitment fee (the “Commitment Shares”).




In connection with the foregoing, we advise you that a member of the SEC’s staff has advised us by telephone that the SEC has entered an order declaring the Registration Statement effective under the Securities Act at [_____] [A.M./P.M.] on [__________], 2020 and we have no knowledge, based solely on our review of the Commission’s “Stop Orders” web  page  (http://sec.gov/litigation/stoporders.shtml), that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are pending before, or threatened by, the SEC and the Purchase Shares and the Commitment Shares are 

 



 

available for resale under the Securities Act pursuant to the Registration Statement and may be issued without any restrictive legend.

 

Very truly yours,
