REGISTRATIONS 
 2.01
Demand Registration. Subject to the restrictions set forth below, if at any time after the date that is six (6) months after the consummation of the IPO the Company shall receive from the Holders (the “Requesting
Holders”) owning as of the date of such request at least twenty percent (20%) of the then outstanding shares of Registrable Securities a written request to 

  
 - 3 - 








 
register at least fifty percent (50%) of the aggregate number of Registrable Securities owned by all of the Requesting Holders as of the date of such request, then the Company will give notice of
such request to all Holders within ten (10) days of receiving such request and shall effect as soon thereafter as practicable, and in any event within forty-five (45) days of the receipt of such request, the Registration under the
Securities Act of all Registrable Securities which any Holder requests to be registered. The Company shall not be obligated to effect, or to take any action to effect, any such registration pursuant to this Section 2.01:

 (a) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the
date of filing of, and ending on a date one hundred eighty (180) days after the effective date of, a Company-initiated Registration; provided that the Company has delivered notice of such Registration to the Holders prior to its receipt of the
Holders’ written request for a demand Registration, and it continues to actively employ in good faith all reasonable efforts to cause such Registration Statement to become effective; or 

(b) if the Holders have requested an Underwritten Registration, the Company and the Holders are unable to obtain the commitment
of underwriters to firmly underwrite the offer; or 
 (c) if the managing underwriter or other investment banker advising the
Company provides the Board of Directors with a good faith estimate that the gross proceeds of the sale of such Registrable Securities is not likely to exceed Five Million Dollars ($5,000,000); or 

(d) if in the good faith judgment of the Board of Directors of the Company, such registration would be seriously detrimental to
the Company and the Board of Directors of the Company concludes, as a result, that it is essential to defer the filing of such Registration Statement at such time, and the Company shall furnish to such Holders a certificate signed by the President
of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is, therefore, essential to
defer the filing of such Registration Statement. In such event, the Company shall have the right to defer such filing (except as provided in subparagraph (a) above) for a period of not more than one hundred eighty (180) days after receipt
of the request of the Holders; provided, however, that the Company shall not defer its obligation in this manner more than once in any 12-month period. 

Furthermore, the Company shall not be required to effect more than two (2) Long-Form Registrations under this Section 2.01 on
behalf of the Holders; provided, however, that a Registration shall not be counted for such purposes unless such Long-Form Registration has become effective and all of the Registrable Securities requested by the Requesting Holders to be
registered on behalf of the Requesting Holders in such Long-Form Registration have been sold, in accordance with Section 3.01(a) of this Agreement. The
Company shall be required to effect an unlimited number of Short-Form Registrations under this Section 2.01 on behalf of the Holders; provided, however, that the Company will not be obligated to effect any such
Short-Form Registration: 

  
 - 4 - 








 (a) if Form S-3 is not available for such
offering; 
 (b) if in the good faith judgment of the Board of Directors of the Company, such registration would be seriously
detrimental to the Company and the Board of Directors of the Company concludes, as a result, that it is essential to defer the filing of such Registration Statement at such time, and the Company shall furnish to such Holders a certificate signed by
the President of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is, therefore,
essential to defer the filing of such Registration Statement. In such event, the Company shall have the right to defer such filing (except as provided in subparagraph (a) above) for a period of not more than one hundred eighty (180) days
after receipt of the request of the Holders; provided, however, that the Company shall not defer its obligation in this manner more than once in any 12-month period; 

(c) if the Company has effected one (1) Short-Form Registration within the six (6) month period prior to the current
request for Short-Form Registration; or 
 (d) if the Registrable Securities to be covered by such registration statement do
not, in the aggregate, exceed $5,000,000. 
 2.02 Piggyback Registration. Each time the Company decides to file a Registration
Statement under the Securities Act (other than on Forms S-4 or S-8 or any successor form for the registration of securities issued or to be issued in connection with a
merger or acquisition or employee benefit plan), the Company shall give written notice thereof to the Holders. The Company shall include in such Registration Statement such Registrable Securities for which it has received written requests for
registration within thirty (30) days after such written notice has been given. If in the good faith judgment of the managing underwriter in any Underwritten Offering, the inclusion of all of the Registrable Securities and any other Common Stock
(including shares of Common Stock issued or issuable upon the exercise or conversion of other securities of the Company) requested to be registered by third parties holding similar registration rights (the “Other Securities”)
would interfere with the successful marketing of a smaller number of such securities, then the number of Registrable Securities and Other Securities to be included in the offering (except for shares to be issued by the Company in an offering
initiated by the Company) shall be reduced as provided herein. The Company shall advise all holders of securities requesting registration of the underwriters’ decision, and the number of securities that are entitled to be included in the
Underwritten Registration shall be allocated first to the Company for securities being sold for its own account and thereafter as set forth in Section 2.03 below. If any Person does not agree to the terms of any such
underwriting, such Person shall be excluded therefrom by written notice from the Company or the underwriter. Any Registrable Securities or Other Securities excluded or withdrawn from such underwriting shall be withdrawn from such Registration. If
securities are so withdrawn from the Registration and if the number of Registrable Securities and Other Securities to be included in such Registration was previously reduced as a result of marketing factors, the Company shall then offer to all
persons who have retained the right to include securities in the Registration the right to include additional securities in the Registration in an aggregate amount equal to the number of securities so withdrawn, with such securities to be allocated
among the persons requesting additional inclusion in accordance with Section 2.03 below. 

  
 - 5 - 








 2.03 Registration Cutback. In any circumstance in which all of the Registrable Securities
and Other Securities requested to be included in a Registration on behalf of the Holders or other selling stockholders cannot be so included as a result of limitations of the aggregate number of Registrable Securities and Other Securities that may
be so included, the number of Registrable Securities and Other Securities that may be so included shall be allocated among the Holders and other selling stockholders requesting inclusion of Other Securities pro rata on the basis of the number of
Registrable Securities and Other Securities that would be held by such Holders and other selling stockholders, assuming conversion. If any Holder or other selling stockholder does not request inclusion of the maximum number of shares of Registrable
Securities and Other Securities allocated to such Holder or other selling stockholder pursuant to the above-described procedure, the remaining portion of such Holder’s or other selling stockholder’s allocation shall be reallocated among
those requesting Holders and other selling stockholders whose allocations did not satisfy their requests, pro rata on the basis of the number of Registrable Securities and Other Securities which would be held by such Holders and other selling
stockholders, assuming conversion, and this procedure shall be repeated until all of the shares of Registrable Securities and Other Securities which may be included in the registration on behalf of Holders and other selling stockholders have been so
allocated. 
 2.04 Cancellation of Registration. A majority of the Requesting Holders shall have the right to cancel a proposed
Registration of Registrable Securities pursuant to Section 2.01 when, (i) in their discretion, market conditions are so unfavorable as to be seriously detrimental to an offering pursuant to such Registration or
(ii) the request for cancellation is based upon material adverse information relating to the Company that is different from the information known to the Requesting Holders at the time of their written request for a Demand Registration. Such
cancellation of a Registration shall not be counted as one of the two (2) Long-Form Registrations provided for in Section 2.01 above and notwithstanding anything to the contrary in this Agreement, the Company shall be
responsible for the expenses of the Requesting Holders incurred in connection with the Registration prior to the time of such cancellation. 

ARTICLE III

3.03 Requirements for Participation in Underwritten Offerings. No person may participate in any Underwritten Offering for equity

3.05 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be

15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings. The Company further covenants that it will take such further action as any Holder may reasonably request, all to the extent required
from time to time to enable such Holder to sell shares of Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act
(“Rule 144”), including providing any legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such
requirements.

 3.06 Indemnification. 

(a) The Company agrees to indemnify, to the extent permitted by law, the Holder of Registrable Securities, its officers and
directors and each Person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material
fact contained in any Registration Statement, prospectus or preliminary prospectus 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 not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company will indemnify the underwriters, their officers and
directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Holder. 

(b) In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder
will furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or prospectus and, to the extent permitted by law, will indemnify the Company, its
directors and officers and agents and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees)
resulting from any untrue statement of material fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided,
however, that the obligation to indemnify will be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities will be in proportion to and limited to the gross
proceeds received by such Holder from the sale or Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities will indemnify the underwriters, their officers, directors and each Person who controls such
underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to indemnification of the Company. 

(c) Any Person entitled to indemnification herein will (i) 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 (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, 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 will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent
will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified


  
 - 10 - 








 
parties with respect to such claim. No indemnifying party shall, without the 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. 
 (d) The
indemnification provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and will
survive the transfer of securities. The Company and each Holder of Registrable Securities participating in the offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the
event the Company’s or such holder’s indemnification is unavailable for any reason. 
 (e) If the indemnification
provided for in this Section 3.06 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses 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, claims, damages, liabilities and expenses 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 or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, 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; provided, however, that the liability of any Holder
under this Section 3.06(f) shall be limited to the amount of the gross proceeds received by such Holder in the offering giving rise to such liability. 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 subsections (a) through (c) above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any
investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 3.06(f) were determined by pro rata allocation or by any other method of allocation
which does not take account of the equitable considerations referred to in this Section 3.06(f). 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 3.06(f) from any Person who was not guilty of such fraudulent misrepresentation.

 3.07 Restrictions on Public Sales. In consideration of the agreements contemplated herein,
the Holders and the Company further agree to the following restrictions: 
 (a) Each Holder of Registrable Securities, if the
Company or the managing underwriters so request in connection with any Underwritten Registration of the Company’s securities, will not, without the prior written consent of the Company or such underwriters, effect any sale of the Registrable
Securities to the public pursuant to a public offering or otherwise, including any sale pursuant to Rule 144 (each of the foregoing, a “Prohibited Sale”), during the seven (7) days prior to, and during the one hundred
eighty (180) day period commencing on, the effective date of such Underwritten Registration, except in connection with such Underwritten Registration; provided, however, that the foregoing shall not apply to restrict the sale by
any Stockholder who together with any of its Affiliates, as such term is defined in the Securities Act, holds less than two percent (2%) of the Common Stock on a fully diluted basis. The restrictions of this Section 3.07(a)
shall not be waived or modified with respect to any Holder of Registrable Securities unless such restrictions are so waived or modified with respect to all of the Holders of Registrable Securities. 

(b) The Company agrees not to effect any Prohibited Sale or other distribution of its equity securities, or any securities
convertible into or exchangeable or exercisable for such equity securities, during the period commencing on the seventh (7th) day prior to, and ending on the one hundred eightieth (180th) day following, the effective date of any underwritten Demand Registration or Piggyback Registration, except in connection with any such Underwritten Registration and except for any offering
pursuant to an employee benefit plan and registered on Form S-8 (or any successor form).

or other transfer of any or all of such Holder’s Registrable Securities to such assignee (a “Permitted Assignment”), upon written notice to the remaining Holders and the Company. As a condition to the effectiveness of
any Permitted Assignment under this Agreement, the assignee shall execute an addendum to this Agreement (in form and substance satisfactory to the Company and its counsel), which evidences the assignee’s agreement to take the Registrable
Securities subject to the terms of this Agreement. With respect to any person who is subsequently issued Registrable Securities by the Company after the date of this Agreement prior to becoming a Holder hereunder, the Company shall, as a condition
to issuing such securities, cause such person to execute an addendum to this Agreement (in form and substance satisfactory to the Company and its counsel), evidencing that such person is a Holder and shall have the rights of a Holder hereunder,
subject to the terms and conditions of this Agreement. 
 4.03 Counterparts. This Agreement may be executed in multiple counterparts
(including facsimile counterparts), each of which shall be deemed an original, and all of which together shall constitute the same instrument, but only one of which need be produced. 

4.04 Governing Law; Venue. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES
EXPRESSLY AGREE THAT THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF DELAWARE AS APPLIED TO AGREEMENTS AMONG DELAWARE RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN DELAWARE, WITHOUT REGARD TO THE
CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION. 
 4.05 Amendments and Modifications. Upon the written consent of the Company and the
Holders who hold at least sixty-six and two-thirds percent (66-2/3%) of the Registrable Securities, compliance with any of the
provisions, covenants and conditions set forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment
hereto or waiver hereof that adversely affects one Holder, solely in its capacity as a holder of the shares of capital stock of the Company, in a manner that is materially different from the other Holders (in such capacity) shall require the consent
of the Holder so affected. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a
waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or
thereunder by such party. 
 4.06 Other Registration Rights. The Company will not grant to any Person the right to require the Company
to register any equity securities of the Company, or any securities convertible or exchangeable into or exercisable for such securities, which conflicts with the registration rights granted hereunder. 

4.07 Termination. This Agreement shall terminate and the registration rights granted hereunder shall expire on the date that is five
(5) years after the effective date of the IPO; provided that such termination and expiration shall not affect registration rights exercised prior to such date.
