 2. REGISTRATION UNDER THE SECURITIES
ACT. 
  
 2.1. Demand Registration. 
  
 (a) Right to Demand Registration. Subject to Section 2.1(c), at any
time after May 17,2004 or from time to time thereafter the Majority Holders shall have the right to request in writing that the Company register all or part of such Holders’ Registrable Securities (a “Request”) (which Request shall
specify the amount of Registrable Securities intended to be disposed of by such requesting Holders and the intended method of disposition thereof) by filing with the SEC a Demand Registration Statement. As promptly as practicable, but no later than
15 days after receipt of a Request, the Company shall give written notice of such requested registration to all other Holders of Registrable Securities. Subject to Section 2.1(b), the Company shall include in a Demand Registration (i) the
Registrable Securities intended to be disposed of by the Initiating Holders and (ii) the Registrable Securities intended to be disposed of by any other Holder which shall have made a written request (which request shall specify the amount of
Registrable Securities to be registered and the intended method of disposition thereof) to the Company for inclusion thereof in such registration within 20 days after the receipt of such written notice from the Company. The Company shall, as
expeditiously as possible, following a Request, use its reasonable best efforts to cause to be filed with the SEC a Demand Registration Statement providing for the registration under the Securities Act of the Registrable Securities which the Company
has been so requested to register by all such Holders, to the extent necessary to permit the disposition of such Registrable Securities to be registered in accordance with the intended methods of disposition thereof specified in such Request or
further requests (including, without limitation, by means of a shelf registration pursuant to Rule 415 under the Securities Act (a “Shelf Registration”) if so requested and if the Company is then eligible to use such a registration). The
Company shall use its reasonable best efforts to have such Demand Registration Statement declared effective by the SEC as soon as practicable thereafter and to keep such Demand Registration Statement continuously effective for the period specified
in Section 4.1(b). 
  
 A Request may be withdrawn prior to the
filing of the Demand Registration Statement by the Majority Holders of the Registration (a “Withdrawn Request”) and a Demand Registration Statement may be withdrawn prior to the effectiveness thereof by the Majority Holders of the
Registration (a “Withdrawn Demand Registration”), and such withdrawals shall be treated as a Demand Registration which shall have been effected pursuant to this Section 2.1, 

  

 -5- 







 
unless the Holders of Registrable Securities to be included in such Registration Statement reimburse the Company for its reasonable out-of-pocket
Registration Expenses relating to the preparation and filing of such Demand Registration Statement (to the extent actually incurred), in which case such withdrawal shall not be treated as a Demand Registration effected pursuant to this Section 2.1
(and shall not be counted toward the number of Demand Registrations); provided, however, that if a Withdrawn Request or Withdrawn Registration Statement is made (A) because of a material adverse change in the business, financial
condition or prospects of the Company, or (B) because the sole or lead managing Underwriter advises that the amount of Registrable Securities to be sold in such offering be reduced pursuant to Section 2.1(b) by more than 15% of the Registrable
Securities to be included in such Registration Statement, then such withdrawal shall not be treated as a Demand Registration effected pursuant to this Section 2.1 (and shall not be counted toward the number of Demand Registrations), and the Company
shall pay all Registration Expenses in connection therewith. Any Holder requesting inclusion in a Demand Registration may, at any time prior to the effective date of the Demand Registration Statement (and for any reason) revoke such request by
delivering written notice to the Company revoking such requested inclusion. 
  
 The registration rights granted pursuant to the provisions of this Section 2.1 shall be in addition to the registration rights granted pursuant to the other provisions of Section 2 hereof. 
  
 (b) Priority in Demand Registrations. If a Demand Registration
involves an Underwritten Offering, and the sole or lead managing Underwriter, as the case may be, of such Underwritten Offering shall advise the Company in writing (with a copy to each Holder requesting registration) on or before the date five days
prior to the date then scheduled for such offering that, in its opinion, the amount of Registrable Securities requested to be included in such Demand Registration exceeds the number which can be sold in such offering within a price range acceptable
to the Majority Holders of the Registration (such writing to state the basis of such opinion and the approximate number of Registrable Securities which may be included in such offering), and the Request is not thereafter withdrawn, the Company shall
include in such Demand Registration, to the extent of the number which the Company is so advised may be included in such offering, the Registrable Securities requested to be included in the Demand Registration by the Holders allocated pro
rata in proportion to the number of Registrable Securities requested to be included in such Demand Registration by each of them. In the event the Company shall not, by virtue of this Section 2.1(b), include in any Demand Registration all of
the Registrable Securities of any Holder requested to be included in such Demand Registration, such Holder may, upon written notice to the Company given within five days of the time such Holder first is notified of such matter, further reduce the
amount of Registrable Securities it desires to have included in such Demand Registration, whereupon only the Registrable Securities, if any, that it desires to have included will be so included and the Holders not so reducing shall be entitled to a
corresponding pro rata increase in the amount of Registrable Securities to be included in such Demand Registration. 
  
 (c) Limitations on Registrations. The rights of Holders of Registrable Securities to request Demand Registrations pursuant to Section 2.1(a) are
subject to the following limitations: (i) in no event shall the Company be required to effect a Demand Registration after February 16, 2009 and (ii) in no event shall the Company be required to effect, 

  

 -6- 







 
in the aggregate, more than 3 Demand Registrations pursuant to this Section 2.1, provided, however, that such number shall be increased to the
extent the Company (x) does not include in what would otherwise be the final registration for which the Company is required to pay Registration Expenses the number of Registrable Securities requested to be registered by the Holders by reason of
Section 2.1(b) or (y) terminates a Shelf Registration pursuant to Section 2.3 prior to the time that all Registrable Securities covered by such Shelf Registration have been sold. 
  
 (d) Underwriting; Selection of Underwriters. Notwithstanding anything to the contrary contained in Section 2.1(a), if
the Initiating Holders holding a majority of the Registrable Securities for which registration was requested in the Request so elect, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of a firm
commitment Underwritten Offering and such Initiating Holders may require that all Persons (including other Holders) participating in such registration sell their Registrable Securities to the Underwriters at the same price and on the same terms of
underwriting applicable to the Initiating Holders. If any Demand Registration involves an Underwritten Offering, the sole or managing Underwriters and any additional investment bankers and managers to be used in connection with such registration
shall be selected by the Company subject to the approval of the Initiating Holders holding a majority of the Registrable Securities for which registration was requested in the Request (such approval not to be unreasonably withheld or delayed).

  
 (e) Effective Registration Statement; Suspension. A
Demand Registration Statement shall not be deemed to have become effective (and the related registration will not be deemed to have been effected) (i) unless it has been declared effective by the SEC and remains effective in compliance with the
provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Demand Registration Statement for the time period specified in Section 4.1(b), (ii) if the offering of any Registrable Securities pursuant
to such Demand Registration Statement is unable to proceed as a result of any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court, or (iii) if, in the case of an Underwritten Offering, the
conditions to closing specified in an underwriting agreement to which the Company is a party are not satisfied (other than by the sole reason of any breach or failure by the Holders of Registrable Securities) and are not otherwise waived.

  
 (f) Registration of Other Securities. Whenever the
Company shall effect a Demand Registration, no securities other than the Registrable Securities shall be covered by such registration unless the Majority Holders of the Registration shall have consented in writing to the inclusion of such other
securities (which consent shall not be unreasonably withheld). 
  
 (g) Registration Statement Form. Registrations under this Section 2.1 shall be on such appropriate registration form of the SEC (i) as shall be reasonably selected by the Company, and (ii) which shall be available for the sale of
Registrable Securities in accordance with the intended method or methods of disposition specified in the requests for registration. The Company agrees to include in any such Registration Statement all information which any selling Holder, upon
advice of counsel, shall reasonably request. 
  
 (h) Other
Registrations. During the period (i) beginning on the date of a Request and (ii) ending on the date that is 90 days after the date that a Demand Registration 

  

 -7- 







 
Statement filed pursuant to such Request has been declared effective by the SEC or, if the Holders shall withdraw such Request or such Demand Registration
Statement, on the date of such Withdrawn Request or such Withdrawn Registration Statement, the Company shall not, without the consent of the Majority Holders of the Registration, file a registration statement pertaining to any other securities of
the Company. 
  
 2.2. Incidental Registration. 
  
 (a) Right to Include Registrable Securities. If the Company at any
time after May 17, 2004 or from time to time thereafter proposes to register any of its securities under the Securities Act (other than in a registration on Form S-4 or S-8 or any successor form to such forms and other than pursuant to Section 2.1
or 2.3) whether or not pursuant to registration rights granted to other holders of its securities and whether or not for sale for its own account, the Company shall deliver prompt written notice (which notice shall be given at least 15 days prior to
such proposed registration) to all Holders of Registrable Securities of its intention to undertake such registration, describing in reasonable detail the proposed registration and distribution (including the anticipated range of the proposed
offering price, the class and number of securities proposed to be registered and the distribution arrangements) and of such Holders’ right to participate in such registration under this Section 2.2 as hereinafter provided. Subject to the other
provisions of this paragraph (a) and Section 2.2(b), upon the written request of any Holder made within 15 days after the receipt of such written notice (which request shall specify the amount of Registrable Securities to be registered and the
intended method of disposition thereof), the Company shall effect the registration under the Securities Act of all Registrable Securities requested by Holders to be so registered (an “Incidental Registration”), to the extent required to
permit the disposition (in accordance with the intended methods thereof as aforesaid) of the Registrable Securities so to be registered, by inclusion of such Registrable Securities in the Registration Statement which covers the securities which the
Company proposes to register and shall cause such Registration Statement to become and remain effective with respect to such Registrable Securities in accordance with the registration procedures set forth in Section 4. If an Incidental Registration
involves an Underwritten Offering, promptly after notification to the Company from the Underwriter of the price at which such securities are to be sold, the Company shall so advise each participating Holder. The Holders requesting inclusion in an
Incidental Registration may, at any time prior to the effective date of the Incidental Registration Statement (and for any reason), revoke such request by delivering written notice to the Company revoking such requested inclusion. 
  
 If at any time after giving written notice of its intention to register any
securities and prior to the effective date of the Incidental Registration Statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration of such securities, the Company may,
at its election, give written notice of such determination to each Holder of Registrable Securities and, thereupon, (A) in the case of a determination not to register, the Company shall be relieved of its obligation to register any Registrable
Securities in connection with such registration (but not from its obligation to pay the Registration Expenses incurred in connection therewith), without prejudice, however, to the rights of Holders to cause such registration to be effected as a
registration under Section 2.1 or 2.3(a) and (B) in the case of a determination to delay such registration, the Company shall be permitted to delay the registration of such Registrable Securities for the same period as the delay 

  

 -8- 







 
in registering such other securities; provided, however, that if such delay shall extend beyond 120 days from the date the Company received a
request to include Registrable Securities in such Incidental Registration, then the Company shall again give all Holders the opportunity to participate therein and shall follow the notification procedures set forth in the preceding paragraph. There
is no limitation on the number of such Incidental Registrations pursuant to this Section 2.2 which the Company is obligated to effect. 
  
 The registration rights granted pursuant to the provisions of this Section 2.2 shall be in addition to the registration rights granted pursuant to the
other provisions of Section 2 hereof. 
  
 (b) Priority in
Incidental Registration. If an Incidental Registration involves an Underwritten Offering (on a firm commitment basis), and the sole or the lead managing Underwriter, as the case may be, of such Underwritten Offering shall advise the Company in
writing (with a copy to each Holder requesting registration) on or before the date five days prior to the date then scheduled for such offering that, in its opinion, the amount of securities (including Registrable Securities) requested to be
included in such registration exceeds the amount which can be sold in such offering without materially interfering with the successful marketing of the securities being offered (such writing to state the basis of such opinion and the approximate
number of such securities which may be included in such offering without such effect), the Company shall include in such registration, to the extent of the number which the Company is so advised may be included in such offering without such effect,
(i) in the case of a registration initiated by the Company, (A) first, the securities that the Company proposes to register for its own account (but solely to the extent that the proceeds thereof shall not be used to purchase shares of common stock
of the Company or other securities of the Company), (B) second, the Registrable Securities requested to be included in such registration by the Holders, allocated pro rata in proportion to the number of Registrable Securities requested
to be included in such registration by each of them, and (C) third, other securities of the Company to be registered on behalf of any other Person, and (ii) in the case of a registration initiated by a Person other than the Company, (A) first, the
Registrable Securities requested to be included in such registration by any Persons initiating such registration requested to be included in such registration by any Persons initiating such registration, (B) second, the Registrable Securities
requested to be included in such registration by the Holders and any other Persons (not including Affiliates of the Company), allocated pro rata in proportion to the number of securities requested to be included in such registration by
each of them, and (C) third, the securities that the Company proposes to register for the account of it and its Affiliates, provided, however, that in the event the Company will not, by virtue of this Section 2.2(b), include in any
such registration all of the Registrable Securities of any Holder requested to be included in such registration, such Holder may, upon written notice to the Company given within three days of the time such Holder first is notified of such matter,
reduce the amount of Registrable Securities it desires to have included in such registration, whereupon only the Registrable Securities, if any, it desires to have included will be so included and the Holders not so reducing shall be entitled to a
corresponding pro rata increase in the amount of Registrable Securities to be included in such registration.

 2.3. S-3 Registration; Shelf Registration. 
  
 S-3 Registration. If at any time after May 17, 2004 (i) the Majority Holder(s) request that the Company file a
registration statement on S-3 or any successor form thereto for a public offering of all of the Registrable Securities, and (ii) the Company is a registrant entitled to use S-3 or any successor form thereto to register such securities, then the
Company shall, as expeditiously as possible following such Request, use its reasonable best efforts to register under the Securities Act on S-3 or any successor form thereto, for public sale in accordance with the intended methods of disposition
specified in such Request or any subsequent requests (including, without limitation, by means of a Shelf Registration) all of the Registrable Securities; provided, that if such registration is for an Underwritten Offering, the terms of Sections
2.1(b) and 2.1(d) shall apply (and any reference to “Demand Registration” therein shall, for purposes of this Section 2.3, instead be deemed a reference to “S-3 Registration”). Whenever the Company is required by this Section 2.3
to use its reasonable best efforts to effect the registration of Registrable Securities, each of the procedures and requirements of Section 2.1(a) and 2.1(e) (including but not limited to the requirements that the Company (A) notify all Holders of
Registrable Securities from whom such Request for registration has not been received and provide them with the opportunity to participate in the offering and (B) use its reasonable best efforts to have such S-3 Registration Statement declared and
remain effective for the time period specified herein) shall apply to such registration (and any reference in such Sections 2.1(a) and 2.1(e) to “Demand Registration” shall, for purposes of this Section 2.3, instead be deemed a reference
to “S-3 Registration”). Notwithstanding anything to the contrary contained herein, no Request may be made under this Section 2.3 within 90 days after the effective date of a Registration Statement filed by the Company covering a firm
commitment Underwritten Offering in which the Holders of Registrable Securities shall have been entitled to join pursuant to this Agreement in which there shall have been effectively registered all shares or units of Registrable Securities as to
which registration shall have been requested. There is no limitation on the number of S-3 Registrations that the Company is obligated to effect. 
  
 The Company shall include as selling securityholders under the S-3 Registration Statement all Holders of Registrable Securities who request in accordance
with the procedures herein to be so included, and (by filing a prospectus supplement or supplements, if required by law or SEC rules) such other Holders of Registrable Securities that so request from time to time after the effectiveness of such S-3
Registration Statement, in each case after such Holder provides to the Company such information as the Company shall request in accordance with Section 4.2. 
  
 The registration rights granted pursuant to the provisions of this Section 2.3(a) shall be in addition to the registration rights granted pursuant to the
other provisions of this Section 2; provided, however, that if a S-3 Registration Statement has been filed and is effective with respect to any Registrable Securities, the Company may satisfy its obligations with respect to a demand
registration with respect to such Registrable Securities by utilizing such S-3 Registration Statement if the offer and sale of such Registrable Securities can be accomplished thereunder. 
  
 (a) Shelf Registration. If a request made pursuant to Section 2.1 or 2.3(a) is for a Shelf Registration, the Company
shall use its reasonable best efforts to keep the Shelf Registration continuously effective through the date on which all of the Registrable Securities covered by such Shelf Registration may be sold pursuant to Rule 144(k) under the Securities Act


  

 -10- 







 
(or any successor provision having similar effect); provided, however, that prior to the termination of such Shelf Registration, the Company
shall first furnish to each Holder of Registrable Securities participating in such Shelf Registration (i) an opinion, in form and substance satisfactory to the Majority Holders of the Registration, of counsel for the Company satisfactory to the
Majority Holders of the Registration stating that such Registrable Securities are freely saleable pursuant to Rule 144(k) under the Securities Act (or any successor provision having similar effect) or (ii) a “No-Action Letter” from the
staff of the SEC stating that the SEC would not recommend enforcement action if the Registrable Securities included in such Shelf Registration were sold in a public sale other than pursuant to an effective registration statement. 
  
 2.4. Underwritten Offerings . 
  
 (a) Demand Underwritten Offerings. If requested by the sole or lead
managing Underwriter for any Underwritten Offering effected pursuant to a Demand Registration or an F-3 or S-3 Registration, the Company shall enter into a customary underwriting agreement with the Underwriters for such offering, such agreement to
be reasonably satisfactory in substance and form to the Company and each Holder of Registrable Securities participating in such offering and to contain such representations and warranties by the Company and such other terms as are generally
prevailing in agreements of that type, including, without limitation, indemnification and contribution to the effect and to the extent provided in Section 5. 
  
 (b) Holders of Registrable Securities to be Parties to Underwriting Agreement. The Holders of Registrable Securities to be distributed by
Underwriters in an Underwritten Offering contemplated by Section 2 shall be parties to the underwriting agreement between the Company and such Underwriters and may, at such Holders’ option, require that any or all of the representations and
warranties by, and the other agreements on the part of, the Company to and for the benefit of such Underwriters shall also be made to and for the benefit of such Holders of Registrable Securities and that any or all of the conditions precedent to
the obligations of such Underwriters under such underwriting agreement be conditions precedent to the obligations of such Holders of Registrable Securities; provided, however, that the Company shall not be required to make any
representations or warranties with respect to written information specifically provided by a selling Holder for inclusion in the Registration Statement. No Holder shall be required to make any representations or warranties to, or agreements with,
the Company or (in the case of an Incidental Registration) the Underwriters other than representations, warranties or agreements regarding such Holder, such Holder’s Registrable Securities and such Holder’s intended method of disposition.

  
 (c) Participation in Underwritten Registration.
Notwithstanding anything herein to the contrary, no Person may participate in any underwritten registration hereunder unless such Person (i) agrees to sell its securities on the same terms and conditions provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangement and (ii) accurately completes and executes in a timely manner all questionnaires, powers of attorney, indemnities, custody agreements, underwriting agreements and other documents
reasonably required under the terms of such underwriting arrangements. 
  
 2.5. Expenses. Except as stated herein, the Company shall pay all Registration Expenses in connection with any Demand Registration, Incidental Registration, F-3 or S-3 

  

 -11- 







 
Registration or Shelf Registration whether or not such registration shall become effective and whether or not all Registrable Securities originally requested
to be included in such registration are withdrawn or otherwise ultimately not included in such registration, except as otherwise provided with respect to a Withdrawn Request and a Withdrawn Demand Registration in Section 2.1(a). 
  
 2.6. Postponements.The Company shall be entitled to postpone a
Demand Registration and an F-3 or S-3 Registration and to require the Holders of Registrable Securities to discontinue the disposition of their securities covered by a Shelf Registration during any Blackout Period (as defined below) (i) if the Board
of Directors of the Company determines in good faith that effecting such a registration or continuing such disposition at such time would have a material adverse effect upon a proposed sale of all (or substantially all) of the assets of the Company
or a merger, reorganization, recapitalization or similar current transaction materially affecting the capital structure or equity ownership of the Company, or (ii) if the Company is in possession of material information which the Board of Directors
of the Company determines in good faith it is not in the best interests of the Company to disclose in a registration statement at such time; provided, however, that the Company may only delay a Demand Registration or an F-3 or S-3
Registration pursuant to this Section 2.6 by delivery of a Blackout Notice (as defined below) within 10 days of delivery of the request for such Registration under Section 2.1 or Section 2.3, as applicable, and may delay a Demand Registration or an
F-3 or S-3 Registration and require the Holders of Registrable Securities to discontinue the disposition of their securities covered by a Shelf Registration only for a reasonable period of time not to exceed 45 days (or such earlier time as such
transaction is consummated or no longer proposed or the material information has been made public) (the “Blackout Period”). There shall not be more than one Blackout Period in any 12 month period. The Company shall promptly notify the
Holders in writing (a “Blackout Notice”) of any decision to postpone a Demand Registration or an F-3 or S-3 Registration or to discontinue sales of Registrable Securities covered by a Shelf Registration pursuant to this Section 2.6 and
shall include a general statement of the reason for such postponement, an approximation of the anticipated delay and an undertaking by the Company promptly to notify the Holders as soon as a Demand Registration or an F-3 or S-3 Registration may be
effected or sales of Registrable Securities covered by a Shelf Registration may resume. In making any such determination to initiate or terminate a Blackout Period, the Company shall not be required to consult with or obtain the consent of any
Holder, and any such determination shall be the Company’s sole responsibility. Each Holder shall treat all notices received from the Company pursuant to this Section 2.6 in the strictest confidence and shall not disseminate such information. If
the Company shall postpone the filing of a Demand Registration Statement or an F-3 or S-3 Registration Statement, the Majority Holders who were to participate therein shall have the right to withdraw the request for registration. Any such withdrawal
shall be made by giving written notice to the Company within 10 days after receipt of the Blackout Notice. Such withdrawn registration request shall not be treated as a Demand Registration effected pursuant to Section 2.1 (and shall not be counted
towards the number of Demand Registrations effected pursuant to Section 2.1(c)), and the Company shall pay all Registration Expenses in connection therewith.

 3.1. Restrictions on Sale by Holders of Registrable Securities. Each Holder of Registrable Securities agrees, by
acquisition of such Registrable Securities, if timely requested in writing by the sole or lead managing Underwriter, not to make any short sale of, loan, grant any option for the purchase of or effect any sale or distribution, of any of the
Company’s equity securities (or any security convertible into or exchangeable or exercisable for any of the Company’s equity securities) during the nine business days (as such term is used in Regulation M under the Exchange Act) prior to,
and during the time period reasonably requested by the sole or lead managing Underwriter not to exceed 90 days, beginning on the effective date of the applicable registration statement (except as part of such underwritten registration or pursuant to
registrations on Forms S-4 or S-8 or any successor form to such forms), unless the sole or lead Managing Underwriter in such Underwritten Offering otherwise agrees.

reasonably requested by the sole or lead managing Underwriter not to exceed 90 days, beginning on the effective date of the applicable registration statement (except as part of such underwritten registration or pursuant to registrations on Forms S-4
or S-8 or any successor form to such forms), unless the sole or lead Managing Underwriter in such Underwritten Offering otherwise agrees. The Company will use its reasonable best efforts to cause each director or officer of the Company and each
holder of 5% or more of the equity securities (or any security convertible into or exchangeable or exercisable for any of its equity securities) of the Company purchased from the Company at any time after the date of this Agreement (other than in a
registered public offering or in a public sale) to so agree.

expeditiously as practicable:

SEC (promptly, and in any event within 60 days after receipt of a request to register Registrable Securities) the requisite Registration Statement to effect such registration, which Registration Statement shall comply as to form in all material
respects with the requirements of the applicable form and include all financial statements required by the SEC to be filed therewith, and the Company shall use its reasonable best efforts to cause such Registration Statement to become effective
(provided, that the Company may discontinue any registration of its securities that are not Registrable Securities, and, under the circumstances specified in Section 2.2, its securities that are Registrable Securities); provided,
however, that before filing a Registration Statement or Prospectus or any amendments or 

  

 -13- 







 
supplements thereto, or comparable statements under securities or blue sky laws of any jurisdiction, the Company shall (i) provide Holders’ Counsel and
any other Inspector (as defined below) with an adequate and appropriate opportunity to participate in the preparation of such Registration Statement and each Prospectus included therein (and each amendment or supplement thereto or comparable
statement) to be filed with the SEC, which documents shall be subject to the review and comment of Holders’ Counsel, and (ii) not file any such Registration Statement or Prospectus (or amendment or supplement thereto or comparable statement)
with the SEC to which Holder’s Counsel, any selling Holder or any other Inspector shall have reasonably objected on the grounds that such filing does not comply in all material respects with the requirements of the Securities Act or of the
rules or regulations thereunder; 
  
 (b) prepare and file with the
SEC such amendments and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary (i) to keep such Registration Statement effective during the periods required herein, and (ii) to comply with the
provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement, in each case until such time as all of such Registrable Securities have been disposed of in accordance with the
intended methods of disposition by the seller(s) thereof set forth in such Registration Statement; provided that except with respect to any Shelf Registration, such period need not extend beyond twelve months after the effective date of the
Registration Statement; and provided further, that with respect to any Shelf Registration, such period need not extend beyond the time period provided in Section 2.3, and which periods, in any event, shall terminate when all
Registrable Securities covered by such Registration Statement have been sold or have otherwise ceased to be Registrable Securities (but not before the expiration of the applicable period referred to in Section 4(3) of the Securities Act and Rule 174
thereunder, if applicable); 
  
 (c) furnish, without charge, to
each selling Holder of such Registrable Securities and each Underwriter, if any, of the securities covered by such Registration Statement, such number of copies of such Registration Statement, each amendment and supplement thereto (in each case
including all exhibits), and the Prospectus included in such Registration Statement (including each preliminary Prospectus) in conformity with the requirements of the Securities Act, and other documents, as such selling Holder and Underwriter may
reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities owned by such selling Holder (the Company hereby consenting to the use in accordance with applicable law of each such Registration Statement
(or amendment or post-effective amendment thereto) and each such Prospectus (or preliminary prospectus or supplement thereto) by each such selling Holder of Registrable Securities and the Underwriters, if any, in connection with the offering and
sale of the Registrable Securities covered by such Registration Statement or Prospectus); 
  
 (d) prior to any public offering of Registrable Securities, use its commercially reasonable efforts to register or qualify all Registrable Securities and other securities covered by such Registration Statement under
such other securities or blue sky laws of such jurisdictions as any selling Holder of Registrable Securities covered by such Registration Statement or the sole or lead managing Underwriter, if any, may reasonably request to enable such selling
Holder to consummate the disposition in such jurisdictions of the Registrable Securities owned by such selling Holder and to continue such registration or qualification in effect in each such jurisdiction for as long as such Registration Statement
remains in effect (including through new filings or 

  

 -14- 







 
amendments or renewals), and do any and all other acts and things which may be necessary or advisable to enable any such selling Holder to consummate the
disposition in such jurisdictions of the Registrable Securities owned by such selling Holder; provided, however, that the Company shall not be required to consent to general service of process in any such jurisdiction; 
  
 (e) use its commercially reasonable efforts to obtain all other approvals,
consents, exemptions or authorizations from such governmental agencies or authorities as may be necessary to enable the selling Holders of such Registrable Securities to consummate the disposition of such Registrable Securities;

covered by such Registration Statement and the sole or lead managing Underwriter, if any: (i) when the Registration Statement, any pre-effective amendment, the Prospectus or any prospectus supplement related thereto or post-effective amendment to

amendments or supplements to the Registration Statement or the Prospectus related thereto or for additional information, (iii) of the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or the initiation
or threat of any proceedings for that purpose, (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the securities or blue sky laws of any
jurisdiction or the initiation of any proceeding for such purpose, (v) of the existence of any fact of which the Company becomes aware or the happening of any event which results in (A) the Registration Statement containing an untrue statement of a
material fact or omitting to state a material fact required to be stated therein or necessary to make any statements therein not misleading, or (B) the Prospectus included in such Registration Statement containing an untrue statement of a material
fact or omitting to state a material fact required to be stated therein or necessary to make any statements therein, in the light of the circumstances under which they were made, not misleading, (vi) if at any time the representations and warranties
contained in any underwriting agreement in respect of such offering cease to be true and correct in all material respects, and (vii) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement would be
appropriate or that there exists circumstances not yet disclosed to the public which make further sales under such Registration Statement inadvisable pending such disclosure and post-effective amendment; and, if the notification relates to an event
described in any of the clauses (ii) through (vii) of this Section 4.1(f), (1) each Holder agrees that such Holder will immediately discontinue disposition of Registrable Securities pursuant to any Registration Statement(s) covering such Registrable
Securities until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated below or receipt of notice that no supplement or amendment is required; provided, that nothing herein shall prevent any Holder,

settling such sale and delivering unlegended shares, if applicable, and (2) the Company shall promptly prepare a supplement or post-effective amendment to such Registration Statement or related Prospectus or any document incorporated therein by
reference or file any other required document so that (1) such Registration Statement 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 

  

 -15- 







 
statements therein not misleading, and (2) as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, such Prospectus
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 in the light of the circumstances under which they were made not misleading (and
shall furnish to each such Holder and each Underwriter, if any, a reasonable number of copies of such Prospectus so supplemented or amended); and if the notification relates to an event described in clause (iii) of this Section 4.1(f), the Company
shall take all reasonable action required to prevent the entry of such stop order or to remove it if entered; 
  
 (g) make available for inspection by any selling Holder of Registrable Securities, any sole or lead managing Underwriter participating in any disposition
pursuant to such Registration Statement, Holders’ Counsel and any attorney, accountant or other agent retained by any such seller or any Underwriter (each, an “Inspector” and, collectively, the “Inspectors”), all financial
and other records, pertinent corporate documents and properties of the Company and any subsidiaries thereof as may be in existence at such time (collectively, the “Records”) as shall be necessary, in the opinion of such Holders’ and
such Underwriters’ respective counsel, to enable them to exercise their due diligence responsibility and to conduct a reasonable investigation within the meaning of the Securities Act, and cause the Company’s and any subsidiaries’
officers, directors and employees, and the independent public accountants of the Company, to supply all information reasonably requested by any such Inspectors in connection with such Registration Statement; 
  
 (h) if such registration involves an Underwritten Offering, obtain an opinion
from the Company’s counsel and a “cold comfort” letter from the Company’s independent public accountants who have certified the Company’s audited financial statements included or incorporated by reference in such
Registration Statement, dated the date of the closing under the underwriting agreement), in customary form and covering such matters as are customarily covered by such opinions and “cold comfort” letters delivered to underwriters in
underwritten public offerings, which opinion and letter shall be reasonably satisfactory to the sole or lead managing Underwriter, if any, and to the Majority Holders of the Registration, and furnish to each Holder participating in the offering and
to each Underwriter, if any, a copy of such opinion and letter addressed to such Holder (in the case of the opinion) and Underwriter (in the case of the opinion and the “cold comfort” letter); 
  
 (i) provide a CUSIP number for all Registrable Securities and provide and

next succeeding each sale of Registrable Securities after the effective date of a Registration Statement, which statement shall cover such 12-month periods, in a 

  

 -16- 







 
manner which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder; 
  
 (k) use its commercially reasonable efforts to cause all such Registrable
Securities to be duly included for quotation on the Nasdaq Stock Market’s National Market (the “Nasdaq National Market”) if the Company’s securities of such class are at the time included on the Nasdaq National Market or listed

Registrable Securities in any Underwritten Offering; 
  
 (n)
cooperate with the selling Holders of Registrable Securities and the sole or lead managing Underwriter, if any, to facilitate the timely preparation and delivery of certificates not bearing any restrictive legends representing the Registrable
Securities to be sold, and cause such Registrable Securities to be issued in such denominations and registered in such names in accordance with the underwriting agreement prior to any sale of Registrable Securities to the Underwriters or, if not an

(q) if requested by the sole or lead managing Underwriter or any selling Holder of Registrable Securities, promptly incorporate in a prospectus
supplement or post-effective amendment such information concerning such Holder of Registrable Securities, the Underwriters or the intended method of distribution as the sole or lead managing Underwriter or the selling Holder of Registrable
Securities reasonably requests to be included therein and as is appropriate in the reasonable judgment of the Company, including, without limitation, information with respect to the number of shares of the Registrable Securities being sold to the

 4.2. Seller Information. The Company may require each selling Holder of Registrable Securities as to which any registration is being effected to
furnish to the Company such information regarding such seller and the disposition of such securities as the Company may from time to time reasonably request in writing; provided, however, that such information shall be used only in
connection with such Registration. If any Registration Statement or comparable statement under “blue sky” laws refers to any Holder by name or otherwise as the Holder of any securities of the Company, then such Holder shall have the right
to require (i) the insertion therein of language, in form and substance satisfactory to such Holder and the Company, to the effect that the holding by such Holder of such securities is not to be construed as a recommendation by such Holder of the
investment quality of the Company’s securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of the Company, and (ii) in the event that such reference to such
Holder by name or otherwise is not in the judgment of the Company, as advised by counsel, required by the Securities Act or any similar federal statute or any state “blue sky” or securities law then in force, the deletion of the reference
to such Holder. 
  
 4.3. Notice to Discontinue. Each Holder
of Registrable Securities agrees by acquisition of such Registrable Securities that, (i) upon receipt of any notice from the Company of the happening of any event of the kind described in Section 4.1(f)(ii) through 4.1(f)(vii), such Holder shall
forthwith discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section
4.1(f) and, if so directed by the Company, such Holder shall deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in such Holder’s possession of the Prospectus covering such Registrable
Securities which is current at the time of receipt of such notice. If the Company shall give any such notice, the Company shall extend the period during which such Registration Statement shall be maintained effective pursuant to this Agreement
(including, without limitation, the period referred to in Section 4.1(b)) by the number of days during the period from and including the date of the giving of such notice pursuant to Section 4.1(f) to and including the date when the Holder shall
have received the copies of the supplemented or amended prospectus contemplated by and meeting the requirements of Section 4.1(f). 
  
 5. INDEMNIFICATION; CONTRIBUTION. 
  
 5.1. Indemnification by the Company. The Company agrees to indemnify and hold harmless, to the fullest extent permitted by law, each Holder of
Registrable Securities, its officers, directors, partners, members, shareholders, employees, Affiliates, advisers, attorneys and agents (collectively, “Agents”) and each Person who controls such Holder (within the 

  

 -18- 







 
meaning of the Securities Act) and its Agents with respect to each registration which has been effected pursuant to this Agreement, against any and all
losses, claims, damages or liabilities, joint or several, actions or proceedings (whether commenced or threatened) in respect thereof, and expenses (as incurred or suffered and including, but not limited to, any and all expenses incurred in
investigating, preparing or defending any litigation or proceeding, whether commenced or threatened, and the reasonable fees, disbursements and other charges of legal counsel) in respect thereof (collectively, “Claims”), insofar as such
Claims arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (including any preliminary, final or summary prospectus and any amendment or supplement thereto)
related to any such registration or any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or any rule
or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, or any qualification or compliance incident thereto; provided, however, that the
Company will not be liable in any such case to the extent that any such Claims arise out of or are based upon any untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact so made in reliance
upon and in conformity with written information furnished to the Company by a Holder, Underwriter or other indemnified person hereunder expressly for use therein. The Company shall also agree to indemnify any Underwriters of the Registrable
Securities, their Agents and each Person who controls any such Underwriter (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Holders of Registrable Securities. Such indemnity
shall remain in full force and effect regardless of any investigation made by or on behalf of any Person who may be entitled to indemnification pursuant to this Section 5 and shall survive the transfer of securities by such Holder or Underwriter.

  
 5.2. Indemnification by Holders. Each Holder, if
Registrable Securities held by it are included in the securities as to which a registration is being effected, agrees to, severally and not jointly, indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and
officers, each other Person who participates as an Underwriter in the offering or sale of such securities and its Agents and each Person who controls the Company against any and all Claims, insofar as such Claims arise out of or are based upon any
untrue or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (including any preliminary, final or summary prospectus and any amendment or supplement thereto) related to such registration, or any
omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, to the extent, but only to the extent, that such untrue statement or alleged untrue statement or
omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by a Holder, Underwriter or other indemnified person hereunder expressly for use therein, or any violation by such Holder of
the Securities Act or any rule or regulation thereunder applicable to such Holder and relating solely to action or inaction solely caused by such Holder as required by such Holder in connection with any such registration, or any qualification or
compliance incident thereto; provided, however, that the aggregate amount which any such Holder shall be required to pay pursuant to this Section 5.2 shall in no event be greater than the amount of the net proceeds received by such
Holder upon the sale of the Registrable Securities pursuant to the Registration Statement giving rise to such 

  

 -19- 







 
Claims less all amounts previously paid by such Holder with respect to any such Claims. Such indemnity shall remain in full force and effect regardless of
any investigation made by or on behalf of any Person who may be entitled to indemnification pursuant to this Section 5 and shall survive the transfer of securities by such Holder or Underwriter. 
  
 5.3. Conduct of Indemnification Proceedings. Promptly after receipt by
an indemnified party of notice of any Claim or the commencement of any action or proceeding involving a Claim under this Section 5, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party pursuant to
Section 5, (i) notify the indemnifying party in writing of the Claim or the commencement of such action or proceeding; provided, that the failure of any indemnified party to provide such notice shall not relieve the indemnifying party of its
obligations under this Section 5, except to the extent the indemnifying party is materially and actually prejudiced thereby and shall not relieve the indemnifying party from any liability which it may have to any indemnified party otherwise than
under this Section 5, and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, however, that any indemnified party shall have the right to
employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (A) the indemnifying party has agreed in writing to pay such fees and
expenses, (B) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such indemnified party within 20 days after receiving notice from such indemnified party that the indemnified
party believes it has failed to do so, or (C) in the reasonable judgment of any such indemnified party, based upon advice of counsel, a conflict of interest shall exist between such indemnified party and the indemnifying party with respect to such
claims; it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to no more than one firm of local counsel) at any time for all such indemnified parties. No indemnifying party shall be liable for
any settlement of any such claim or action effected without its written consent, which consent shall not be unreasonably withheld. No indemnifying party shall, without the consent of the indemnified party, which consent shall not be unreasonably
withheld, consent to entry of any judgment or enter into any settlement of any claim or action in respect of which indemnification or contribution may be sought hereunder, unless such settlement, (i) includes an unconditional release of the
indemnified party from all liability arising out of such action or claim, (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party, and (3) does not provide for any
action on the part of any party other than the payment of money damages which is to be paid in full by the indemnifying party. 
  
 5.4. Contribution. If the indemnification provided for in Section 5.1 or 5.2 from the indemnifying party for any reason is unavailable to (other
than by reason of exceptions provided therein), or is insufficient to hold harmless an indemnified party hereunder in respect of any Claim, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount
paid or payable by such indemnified party as a result of such Claim in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other hand, in connection with the
actions which resulted 

  

 -20- 







 
in such Claim, as well as any other relevant equitable considerations. The relative fault of such 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, has been made by, or relates to information
supplied by, such indemnifying party or indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. If, however, the foregoing allocation is not permitted by
applicable law, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative faults but also the relative benefits of the indemnifying
party and the indemnified party as well as any other relevant equitable considerations. 
  
 5.5. Other Indemnification. Indemnification similar to that specified in the preceding Sections 5.1 and 5.2 (with appropriate modifications) shall be given by the Company and each selling Holder of Registrable
Securities with respect to any required registration or other qualification of securities under any Federal or state law or regulation of any governmental authority, other than the Securities Act. The indemnity agreements contained herein shall be
in addition to any other rights to indemnification or contribution which any indemnified party may have pursuant to law or contract. 
  
 5.6. Indemnification Payments. The indemnification and contribution required by this Section 5 shall be made by periodic payments of the amount
thereof during the course of any investigation or defense, as and when bills are received or any expense, loss, damage or liability is incurred. 
  
 6. General. 
  
 6.1. Adjustments Affecting Registrable Securities. The Company agrees that it shall not effect or permit to occur any combination or subdivision of
shares or other securities that would adversely affect the ability of the Holder of any Registrable Securities to include such Registrable Securities in any registration contemplated by this Agreement or the marketability of such Registrable
Securities in any such registration. 
  
 6.2. Registration
Rights to Others. The Company represents and warrants that it is not currently a party to any agreement with respect to its securities granting registration rights to Persons other than the Holders. If the Company shall at any time hereafter
provide to any holder of any securities of the Company rights with respect to the registration of such securities under the Securities Act (not including any such rights which have been previously granted), without the prior written consent of the
Majority Holders, (i) such rights shall not be in conflict with or adversely affect any of the rights provided in this Agreement to the Holders and (ii) if such rights are provided on terms or conditions more favorable to such holder than the terms
and conditions provided in this Agreement, the Company shall provide (by way of amendment to this Agreement or otherwise) such more favorable terms or conditions to the Holders. 
  
 6.3. Availability of Information; Rule 144; Rule 144A; Other Exemptions. So long as the Company shall not have filed
a registration statement pursuant to Section 12 of the Exchange Act or a registration statement pursuant to the requirements of the Securities Act, the 

  

 -21- 







 
Company shall, at any time and from time to time, upon the request of any Holder of Registrable Securities and upon the request of any Person designated by
such Holder as a prospective purchaser of any Registrable Securities (provided such Person agrees to execute a customary confidentiality agreement relating to the Company’s nonpublic information), furnish in writing to such Holder or such
prospective purchaser, as the case may be, a statement as of a date not earlier than 12 months prior to the date of such request of the nature of the business of the Company and the products and services it offers and copies of the Company’s
most recent balance sheet and profit and loss and retained earnings statements, together with similar financial statements for the two preceding fiscal years, to the extent that the Company shall have been in operation for such time, all such
financial statements to be audited to the extent audited statements are reasonable available, provided that, in any event the most recent financial statements so furnished shall include a balance sheet as of a date less than 16 months prior
to the date of such request, statements of profit and loss and retained earnings for the 12 months preceding the date of such balance sheet, and, if such balance sheet is not as of a date less than 6 months prior to the date of such request,
additional statements of profit and loss and retained earnings for the period from the date of such balance sheet to a date less than 6 months prior to the date of such request. If the Company shall have filed a registration statement pursuant to
the requirements of Section 12 of the Exchange Act or a registration statement pursuant to the requirements of the Securities Act, the Company covenants that it shall timely file any reports required to be filed by it under the Securities Act or the
Exchange Act (including, but not limited to, the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c) of Rule 144 under the Securities Act), and that it shall take such further action as any Holder of Registrable
Securities may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 and
Rule 144A under the Securities Act, as such rules may be amended from time to time, or (ii) any other rule or regulation now existing or hereafter adopted by the SEC. Upon the request of any Holder of Registrable Securities, the Company shall
deliver to such Holder a written statement as to whether it has complied with such requirements. 
  
 6.4. Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified,
supplemented or terminated, and waivers or consents to departures from the provisions hereof may not be given, without the written consent of the Company and the Majority Holders; provided, however, that no such amendment,
modification, supplement, waiver or consent to departure shall reduce the aforesaid percentage of Registrable Securities without the written consent of all of the Holders of Registrable Securities; and provided further, that nothing
herein shall prohibit any amendment, modification, supplement, termination, waiver or consent to departure the effect of which is limited only to those Holders who have agreed to such amendment, modification, supplement, termination, waiver or
consent to departure.

 6.6. Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs,
successors and permitted assigns (including any permitted transferee of Warrants or Registrable Securities). At any time after May 17, 2004, any Holder may assign to any permitted (as determined under the Warrant) transferee of its Warrants or
Registrable Securities (other than a transferee that acquires such Registrable Securities in a registered public offering or pursuant to a sale under Rule 144 of the Securities Act (or any successor rule)), its rights and obligations under this
Agreement; provided, however, (x) that such transferee then holds Warrants or Registrable Securities representing at least 20% of the aggregate number of Warrant Shares issuable or issued pursuant to the Warrant and (y) such transferee
shall promptly notify the Company and by taking and holding such Registrable Securities such permitted transferee shall automatically be entitled to receive the benefits of and be conclusively deemed to have agreed to be bound by and to perform all
of the terms and provisions of this Agreement as if it were a party hereto (and shall, for all purposes, be deemed a Holder under this Agreement). If the Company shall so request any heir, successor or permitted assign (including any permitted
transferee) wishing to avail itself of the benefits of this Agreement shall agree in writing to acquire and hold the Registrable Securities subject to all of the terms hereof. For purposes of this Agreement, “successor” for any entity
other than a natural person shall mean a successor to such entity as a result of such entity’s merger, consolidation, 

  

 -24- 







 
sale of substantially all of its assets, or similar transaction. Except as provided above or otherwise permitted by this Agreement, neither this Agreement
nor any right, remedy, obligation or liability arising hereunder or by reason hereof shall be assignable by any Holder or by the Company without the prior written consent of the other parties hereto. Notwithstanding anything contained in this
Section 6.6, this Agreement shall at all times be freely assignable by any Holder to any Related Fund (as defined in the Financing Agreement) or any other affiliate of any Holder. 
  
 6.7. Counterparts. This Agreement may be executed in two or more counterparts, each of which, when so executed and
delivered, shall be deemed to be an original, but all of which counterparts, taken together, shall constitute one and the same instrument. 
  
 6.8. Descriptive Headings, Etc. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the
meaning of terms contained herein. Unless the context of this Agreement otherwise requires: (1) words of any gender shall be deemed to include each other gender; (2) words using the singular or plural number shall also include the plural or singular
number, respectively; (3) the words “hereof”, “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this
Agreement, and Section and paragraph references are to the Sections and paragraphs of this Agreement unless otherwise specified; (4) the word “including” and words of similar import when used in this Agreement shall mean “including,
without limitation,” unless otherwise specified; (5) “or” is not exclusive; and (6) provisions apply to successive events and transactions. 
  
 6.9. Severability. In the event that any one or more of the provisions, paragraphs, words, clauses, phrases or sentences contained herein, or the
application thereof in any circumstances, is held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision, paragraph, word, clause, phrase or sentence in every other respect
and of the other remaining provisions, paragraphs, words, clauses, phrases or sentences hereof shall not be in any way impaired, it being intended that all rights, powers and privileges of the parties hereto shall be enforceable to the fullest
extent permitted by law. 
  
 6.10. CHOICE OF LAW AND VENUE;
JURY TRIAL WAIVER. THE VALIDITY OF THIS AGREEMENT, THE CONSTRUCTION, INTERPRETATION, AND ENFORCEMENT HEREOF, AND THE RIGHTS OF THE PARTIES HERETO WITH RESPECT TO ALL MATTERS ARISING HEREUNDER OR RELATED HERETO SHALL BE DETERMINED UNDER,
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. 
  
 THE PARTIES AGREE THAT ALL ACTIONS OR PROCEEDINGS ARISING IN CONNECTION WITH THIS AGREEMENT SHALL BE TRIED AND LITIGATED ONLY IN THE STATE AND FEDERAL COURTS LOCATED IN THE COUNTY OF NEW YORK, STATE OF NEW YORK.
THE COMPANY AND THE INITIAL HOLDER WAIVE, TO THE EXTENT PERMITTED UNDER APPLICABLE LAW, ANY RIGHT EACH MAY HAVE TO ASSERT THE DOCTRINE OF FORUM 

  

 -25- 







 
NON CONVENIENS OR TO OBJECT TO VENUE TO THE EXTENT ANY PROCEEDING IS BROUGHT IN ACCORDANCE WITH THIS SECTION 6.10. 
  
 THE COMPANY AND THE INITIAL HOLDER HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO
A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. THE
COMPANY AND THE INITIAL HOLDER REPRESENT THAT EACH HAS REVIEWED THIS WAIVER AND EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN THE EVENT OF LITIGATION, A COPY OF THIS AGREEMENT MAY BE FILED
AS A WRITTEN CONSENT TO A TRIAL BY THE COURT. 
  
 6.11.
Remedies; Specific Performance. The parties hereto acknowledge that money damages would not be an adequate remedy at law if any party fails to perform in any material respect any of its obligations hereunder, and accordingly agree that each
party, in addition to any other remedy to which it may be entitled at law or in equity, shall be entitled to seek to compel specific performance of the obligations of any other party under this Agreement, without the posting of any bond, in
accordance with the terms and conditions of this Agreement in any court specified in Section 6.10 hereof, and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the
defense that there is an adequate remedy at law. Except as otherwise provided by law, a delay or omission by a party hereto in exercising any right or remedy accruing upon any such breach shall not impair the right or remedy or constitute a waiver
of or acquiescence in any such breach. No remedy shall be exclusive of any other remedy. All available remedies shall be cumulative. 
  
 6.12. Entire Agreement. This Agreement, the Financing Agreement, the Warrants and the other Transaction Documents (collectively, (the “Other
Agreements”)) are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein.
There are no restrictions, promises, representations, warranties, covenants or undertakings relating to such subject matter, other than those set forth or referred to herein or in the Other Agreements. This Agreement and the Other Agreements
supersede all prior agreements and understandings between the Company and the other parties to this Agreement with respect to such subject matter. 
  
 6.13. Further Assurances . Each party hereto shall do and perform or cause to be done and performed all such further acts and things and shall
execute and deliver all such other agreements, certificates, instruments and documents as any other party hereto reasonably may request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby. 
  
 6.14. Construction.
The Company and the Initial Holder acknowledge that each of them has had the benefit of legal counsel of its own choice and has been afforded an 

  

 -26- 







 
opportunity to review this Agreement with its legal counsel and that this Agreement shall be construed as if jointly drafted by the Company and the Holders.

  
 6.15. No Inconsistent Agreement. Subject to Sections
2.6 and 6.2, the Company will not hereafter enter into any agreement that restricts, limits or prohibits the exercise of the rights granted to the Holders in this Agreement or the Company’s ability to perform its obligations hereunder.

  
 6.16. Costs and Attorneys’ Fees. In the event that
any action, suit or other proceeding is instituted concerning or arising out of this Agreement, the Company and the Initial Holder agree that the prevailing party shall recover from the non-prevailing party all of such prevailing party’s costs
and reasonable attorneys’ fees incurred in each and every such action, suit or other proceeding, including any and all appeals or petitions therefrom.
