 NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and
agreements hereinafter set forth, the parties hereto agree as follows: 
 1. Certain Definitions. As used
in this Agreement, the following terms shall have the following respective meanings: 
 “Approved Piggyback
Shares” shall mean, in the case of the registration of shares of capital stock by the Company in connection with the initial public offering of the Company’s Common Stock, that number of Registrable Securities that the underwriter(s)
determines may be included as part of such registered offering. 
 “Commission” shall mean the United States
Securities and Exchange Commission or any other federal agency at the time administering the Securities Act and the Exchange Act. 
 “Common Stock” shall mean (i) the Company’s common stock, $0.001 par value per share, and (ii) any other securities into which or for which any of the securities described in clause (i) above may be
converted or exchanged pursuant to a plan of recapitalization, reorganization, merger, sale of assets or otherwise. 
 “Exchange Act” shall mean the Securities Exchange Act of 1934, as amended, or any similar successor federal statute, and the rules and regulations of the Commission thereunder, all as the same shall be in effect at the
time. 
 “Holder” shall mean any person owning or having the right to acquire Registrable Securities or any
transferees thereof in accordance with Section 7 hereof; provided, however, that the Series 1 Holders and the MBI Group Holders shall not be deemed to be Holders for

  

 2 








 
purposes of Section 3(a) or 3(b) hereof and the LRG Holders and the Strategic Investor shall not be deemed to be Holders for the purposes of Section 3(a) hereof. 
 “LRG Piggyback Shares” shall mean the lesser of (i) that number of shares of the Company’s Registrable Securities
held by the LRG Holders or (ii) a percentage of the Approved Piggyback Shares equal to (x) 1.54 multipled by (y) the net amount advanced to the Company under the Loan Agreement (rounded down to the nearest million) divided by
(z) 1,000,000. By way of example with respect to clause (ii), if the Company had received $8,345,231 in net funds from the LRG Holders, the percentage under clause (ii) would be 12.32% and, assuming the Approved Piggyback Shares equal to
500,000, the LRG Piggyback Shares would be 61,600 (provided that the number of shares under clause (i) is greater than 61,600). 
 “Person” shall mean an individual, a corporation, a partnership, a joint venture, a trust, an estate, an unincorporated organization, a limited liability company, a government and any agency or political subdivision
thereof, including, without limitation, any partner, officer, director, member or employee of such Person and any venture capital fund now or hereafter existing which is controlled by or under common control with one or more general partners of such
Person and, with respect to a trust, any beneficiary of such trust. 
 “Preferred Stock” shall mean the Series
A Preferred Stock, the Series B Preferred Stock, the Series C Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock and the Series 1 Preferred Stock. 
 “Registrable Securities” shall mean (i) any shares of Common Stock now held or hereafter acquired by the Investors or
the Series 1 Holders (including, in the case of Series 1 Holders, by the exercise of options), (ii) any shares of Common Stock now held or hereafter acquired by LCP IV or LCP V resulting from the exercise of warrants held by such entities,
(iii) any shares of Common Stock issued to the MBI Group Holders pursuant to the Share Purchase Agreements (whether such shares of Common Stock are issued under the Share Purchase Agreements directly to the MBI Group Holders or to the Escrow
Agent, as such term is defined in each Share Purchase Agreement), (iv) the shares of Common Stock or shares of any other securities issued and issuable upon conversion of the Preferred Stock, (v) any shares of Common Stock issued to the
LRG Holders resulting from the exercise of warrants held by such entities or the conversion of debt owed to such entities, (vi) any shares of Common Stock issued to the Strategic Investor resulting from the exercise of warrants held by the
Strategic Investor, the conversion of debt owed to the Strategic Investor and any other securities issued pursuant to the Purchase Agreement (vii) any other securities issued and issuable with respect to any such shares described in clauses
(i), (ii), (iii), (iv), (v) and (vi) above by way of a stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization (it being understood that for purposes of
this Agreement, a Person will be deemed to be a holder of Registrable Securities whenever such Person has the right to then acquire or obtain from the Company any Registrable Securities, whether or not such acquisition has actually been effected);
provided, however, that notwithstanding anything to the contrary contained herein, “Registrable Securities” shall not at any time include any securities previously sold pursuant to a registered public offering or sold
pursuant to an exemption from the registration requirements of the Securities Act. 
  

 3 








 “Securities Act” shall mean the Securities Act of 1933, as amended, or any
similar successor federal statute, and the rules and regulations of the Commission thereunder, all as the same shall be in effect at the time. 
 2. Piggyback Registrations. If at any time or times after the date hereof the Company shall seek to register any shares of its Common Stock under the Securities Act for sale to the
public for its own account or on the account of others (except with respect to registration statements on Form S-4, S-8 or another form not available for registering the Registrable Securities for sale to the public), the Company will promptly give
written notice thereof to all Holders. If within twenty (20) days after their receipt of such notice one or more Holders request the inclusion of some or all of the Registrable Securities owned by them in such registration, the Company will use
its best efforts to effect the registration under the Securities Act of such Registrable Securities. In the case of the registration of shares of capital stock by the Company in connection with any underwritten public offering, if the underwriter(s)
determines that marketing factors require a limitation on the number of Registrable Securities to be offered, subject to the following sentence, the Company shall not be required to register Registrable Securities of the Holders in excess of the
amount, if any, of shares of the capital stock which the principal underwriter of such underwritten offering shall in good faith agree to include in such offering in addition to any amount to be registered for the account of the Company. In the case
of the Company’s initial public offering of Common Stock, if any limitation of the number of shares of Registrable Securities to be registered by the Holders is required pursuant to this Section 2, the number of shares to be excluded shall
be determined in the following sequence: (i) first, securities held by any Persons not having any contractual, incidental “piggyback” registration rights, (ii) second, securities held by any Persons (other than the Holders)
having contractual, incidental “piggyback” rights pursuant to an agreement which is not this Agreement, (iii) third, Registrable Securities (other than the LRG Piggyback Shares) sought to be included by the Holders (other than the LRG
Holders) as determined on a pro rata basis (based upon the respective holdings of Registrable Securities by such Holders) and (iv) fourth, the LRG Piggyback Shares. In the case of any registered offering other than the Company’s initial
public offering of Common Stock, if any limitation of the number of shares of Registrable Securities to be registered by the Holders is required pursuant to this Section 2, the number of shares to be excluded shall be determined in the
following sequence: (i) first, securities held by any Persons not having any contractual, incidental “piggyback” registration rights, (ii) second, securities held by any Persons (other than the Holders) having contractual,
incidental “piggyback” rights pursuant to an agreement which is not this Agreement and (iii) third, Registrable Securities sought to be included by the Holders as determined on a pro rata basis (based upon the respective holdings of
Registrable Securities by such Holders). 
 3. Required Registrations. 
 (a) Demand Registration. Upon the earlier of (i) July 10, 2006 or (ii) the date that is six
(6) months after the initial public offering of Common Stock by the Company pursuant to an effective registration statement under the Securities Act, on not more than two (2) occasions, the Holders of at least fifty percent (50%) of
the Registrable Securities may request that the Company register under the Securities Act all or a portion of the Registrable Securities held by such requesting Holders having an aggregate value of at least $5,000,000 (based on the then current
market price). A registration will not count as a requested registration under this

  

 4 








 
Section 3(a) until the registration statement relating to such registration has been declared effective by the Commission at the request of the requesting Holders and unless the requesting
Holders are able to register and sell at least 66 2/3rds of the Registrable Securities requested by them to be included in such registration. 
 (b) Form S-3. After the Company’s initial public offering of Common Stock registered under the Securities Act, the Company shall use its best efforts to qualify and remain
qualified to register securities on Form S-3 (or any successor form) under the Securities Act. So long as the Company is qualified to register securities on Form S-3 (or any successor form), the Holders shall have the right to request registration
on Form S-3 (or any successor form) for the Registrable Securities held by such requesting Holders having an aggregate value of at least $500,000 (based on the then current market price), including registrations for the sale of such Registrable
Securities on a delayed or continuous basis pursuant to Rule 415 under the Securities Act. Such requests shall be in writing and shall state the number of shares of Registrable Securities to be disposed of and the intended method of disposition of
such shares by such requesting Holders. Upon receipt of a request for registration under this Section 3(b), the Company shall use all commercially reasonable efforts to effect a registration statement pursuant to this Section 3(b) as soon
as practicable, but in any event no longer than thirty (30) days following receipt of such request. 
 (c)
Registration Requirements. Following a request pursuant to Section 3(a) or (b) above, the Company will notify all of the other Holders and such Holders shall then have twenty (20) days to notify the Company of their
desire to participate in the registration. Thereupon, the Company will use its best efforts to cause such of the Registrable Securities as may be requested by such Holders to be registered under the Securities Act in accordance with the terms of
this Section 3. If the request for registration contemplates an underwritten public offering, the Company shall state such in the written notice and in such event the right of any Person to participate in such registration shall be conditioned
upon their participation in such underwritten public offering and the inclusion of their securities in the underwritten public offering to the extent provided herein. 
 (d) Underwritten Offering. If a requested registration under this Section 3 involves an underwritten public offering and the managing underwriter of such offering determines in
good faith that the number of securities sought to be offered should be limited due to market conditions, then the number of securities to be included in such underwritten public offering shall be reduced to a number deemed satisfactory by such
managing underwriter, provided that the shares to be excluded shall be determined in the following sequence: (i) first, securities held by any Persons not having any contractual, incidental “piggyback” registration rights to
include such securities in the registration statement, (ii) second, securities held by any other Persons (other than the Holders) having contractual, incidental “piggyback” rights to include such securities in the registration
statement and (iii) third, Registrable Securities sought to be included in such registration. If there is a reduction of the number of Registrable Securities pursuant to clause (iii), such reduction shall be made on a pro rata basis (based upon
the respective holdings of Registrable Securities held by such Holders). With respect to a request for registration pursuant to Section 3(a) or (b) which is for an underwritten public offering, the managing underwriter shall be chosen by a
majority-in-interest of the Holders requesting such registration subject to the approval of the Company, which approval will not be unreasonably

  

 5 








 
withheld. If the managing underwriter has not limited the number of Registrable Securities or other securities to be underwritten, the Company may include securities for its own account in such
registration if the managing underwriter so agrees and if the number of Registrable Securities and other securities which would otherwise have been included in such registration and underwriting will not thereby be limited. 
 (e) Postponement. The Company may postpone the filing of any registration statement required hereunder for a reasonable
period of time, not to exceed ninety (90) days in the aggregate during any twelve-month period, if the Company’s Board of Directors determines reasonably and in good faith it would be materially detrimental to the Company and its
stockholders for such registration to be effected at such time. The Company shall not be required to cause a registration statement requested pursuant to this Section 3 to become effective prior to one hundred eighty (180) days following
the effective date of the registration statement filed in connection with the initial public offering of the Company’s equity securities and ninety (90) days following the effective date of any other registration statement initiated by the
Company, if the request for registration has been received by the Company subsequent to the giving of written notice by the Company, made in good faith, to Holders entitled to request demand registrations under this Section 3 that the Company
is commencing to prepare a Company-initiated registration statement (other than a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145, or any other similar rule under the Securities Act, is
applicable); provided, however, that the Company shall use its best efforts to achieve such effectiveness promptly following such period. The Company shall provide written notice to the Holders of Registrable Securities proposed to be
included in such registration of (A) any postponement or withdrawal of the filing pursuant to this subsection (iii), (B) the Company’s decision to file such registration statement following such withdrawal or postponement and
(C) the effectiveness of such registration statement. 
 4. Further Obligations of the Company.
Whenever the Company is required hereunder to register any Registrable Securities, it agrees that it shall also do the following: 
 (a) Pay all expenses of such registrations and offerings (exclusive of underwriting discounts and commissions) and the reasonable fees and expenses of not more than one independent counsel for the Holders in connection with any
registrations pursuant to Sections 2 or 3 hereof; 
 (b) Use its best efforts to diligently prepare and file with the
Commission a registration statement and use its best efforts to cause such registration statement to become effective and prepare and file such amendments and supplements to such registration statement and the prospectus used in connection therewith
as may be necessary to keep such registration statement effective until the earlier of (i) the date which is ninety (90) days following the effectiveness of such registration statement and (ii) the date on which the Holder or Holders
have completed the distribution described in the registration statement relating thereto, and to comply with the provisions of the Securities Act with respect to the sale of securities covered by such registration statement for such period;

 (c) Furnish to each selling Holder such copies of each preliminary and final prospectus and such other documents as
such Holder may reasonably request to facilitate the

  

 6 








 
public offering of its Registrable Securities; 
 (d) Enter into
and perform its obligations under any reasonable underwriting agreement required by the proposed underwriter, if any, in such form and containing such terms as are customary; provided, however, that no Holder shall be required to make
any representations or warranties other than with respect to its title to the Registrable Securities and with respect to any written information provided by the Holder to the Company; 
 (e) Use its best efforts to register or qualify the securities covered by such registration statement under the securities or
“blue sky” laws of such jurisdictions as any selling Holder may reasonably request; provided, that, the Company shall not for any such purpose be required to qualify to do business as a foreign corporation in any jurisdiction
wherein it is not so qualified; 
 (f) Immediately notify each selling Holder, at any time when a prospectus relating to
his, her or its Registrable Securities is required to be delivered under the Securities Act, of the happening of any event as a result of which such prospectus contains an untrue statement of a material fact or omits any material fact necessary to
make the statements therein not misleading, and at the request of any such selling Holder, prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will
not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading; 
 (g) Cause all such Registrable Securities to be listed on each securities exchange or quotation system on which similar securities issued by the Company are then listed or quoted (or if similar
securities issued by the Company are not yet listed or quoted, then on such exchange or quotation system as the Company shall determine); 
 (h) Make available to each selling Holder, any underwriter participating in any disposition pursuant to a registration statement and any attorney, accountant or other agent or representative
retained by any such selling Holder or underwriter (collectively, the “Inspectors”), all financial and other records, pertinent corporate documents and properties of the Company, as shall be reasonably necessary to enable them to
exercise their due diligence responsibility, and cause the Company’s officers, directors and employees to supply all information requested by any such Inspector in connection with such registration statement; provided, however,
that such Inspector shall agree to hold in confidence and trust all information so provided;. 
 (i) Otherwise use its
best efforts to comply with the securities laws of the United States and other applicable jurisdictions and all applicable rules and regulations of the Commission and comparable governmental agencies in other applicable jurisdictions and make
generally available to its stockholders, in each case as soon as practicable, but not later than 45 days after the close of the period covered thereby, an earnings statement of the Company which will satisfy the provisions of Section 11(a) of
the Securities Act; 
 (j) In the case of an underwritten public offering, furnish to each prospective selling Holder a
signed counterpart, addressed to the prospective selling Holder, of (A) an opinion of counsel for the Company dated the effective date of the registration statement, and (B)

  

 7 








 
provided such perspective selling Holder complies with the requests of the Company’s independent public accountants under the Statement on Auditing Standards No. 72, “Letters for
Underwriters and Certain Other Requesting Parties” or any other successor or applicable accounting literature, a “comfort” letter signed by the independent public accountants who have certified the Company’s financial statements
included in the registration statement, covering substantially the same matters with respect to the registration statement (and the prospectus included therein) and (in the case of the accountants’ letter) with respect to events subsequent to
the date of the financial statements, as customarily covered (at the time of such registration) in opinions of counsel and in accountants’ letters delivered to underwriters in underwritten public offerings of securities; and 
 (k) Otherwise cooperate with the underwriter or underwriters, the Commission and other regulatory agencies and take all actions and
execute and deliver or cause to be executed and delivered all documents necessary to effect the registration of any Registrable Securities hereunder. 
 5. Indemnification; Contribution. 
 (a) Incident to any
registration of any Registrable Securities under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless to the fullest extent permitted by law each underwriter, each Holder who offers or sells any such
Registrable Securities in connection with such registration statement (including its partners (including partners of partners and stockholders of any such partners) and directors, officers, employees, representatives, members and agents of any of
them (a “Selling Holder”), and each Person who controls any of them within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (a “Controlling Person”), from and
against any and all losses, claims, damages, expenses and liabilities, joint or several (including any investigation, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or
proceeding or any claim asserted, as the same are incurred), to which they, or any of them, may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as
such losses, claims, damages or liabilities arise out of or are based on (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement (including any related preliminary or definitive
prospectus, or any amendment or supplement to such registration statement or prospectus), (ii) any omission or alleged omission to state in such document a material fact required to be stated in it or necessary to make the statements in it not
misleading or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities laws or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities
laws; provided, however, that the Company will not be liable to the extent that such loss, claim, damage, expense or liability arises from and is based on an untrue statement or omission or alleged untrue statement or omission made in
reliance on and in conformity with information furnished in writing to the Company by such underwriter, Selling Holder or Controlling Person expressly for use in such registration statement. With respect to such untrue statement or omission or
alleged untrue statement or omission in the information furnished in writing to the Company by such Selling Holder expressly for use in such registration statement, such Selling Holder will indemnify and hold harmless each underwriter, the Company
(including its directors, officers, employees, representatives, members and agents), each other Holder

  

 8 








 
(including its partners (including partners of partners and stockholders of such partners) and directors, officers, employees, representatives and agents of any of them, and each Person who
controls any of them within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), from and against any and all losses, claims, damages, expenses and liabilities, joint or several, to which they, or any of
them, may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise to the same extent provided in the immediately preceding sentence. In no event, however, shall the
liability of a Selling Holder for indemnification under this Section 5(a) exceed the net proceeds received by such Selling Holder from its sale of Registrable Securities under such registration statement. 
 (b) If the indemnification provided for in Section 5(a) above for any reason is held by a court of competent jurisdiction to be
unavailable to an indemnified party in respect of any losses, claims, damages, expenses or liabilities referred to therein, then each indemnifying party under this Section 5, in lieu of indemnifying such indemnified party thereunder, shall
contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, expenses or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, the
Selling Holders and the underwriters from the offering of the Registrable Securities and (ii) the relative fault of the Company, the Selling Holders and the underwriters in connection with the statements or omissions which resulted in such
losses, claims, damages, expenses or liabilities, as well as any other relevant equitable considerations; provided, however, that in the event of a registration statement filed in response to a demand under Section 3(a) and in
which the Company does not register any shares of capital stock, the proportion of contribution by the Company, the Selling Holders and the underwriters shall in all cases be governed solely by clause (ii) above. The relative benefits received
by the Company, the Selling Holders and the underwriters shall be deemed to be in the same respective proportions that the net proceeds from the offering (before deducting expenses) received by the Company and the Selling Holders and the
underwriting discount received by the underwriters, in each case as set forth in the table on the cover page of the applicable prospectus, bear to the aggregate public offering price of the securities covered by such registration statement. The
relative fault of the Company, the Selling Holders and the underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company, the Selling Holders or the underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

 The Company and the Selling Holders agree that it would not be just and equitable if contribution pursuant to this
Section 5(b) were determined by pro rata or per capita allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. In no event, however, shall a
Selling Holder be required to contribute any amount under this Section 5(b) in excess of the net proceeds received by such Selling Holder from its sale of Registrable Securities under such registration statement. No person found guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not found guilty of such fraudulent misrepresentation. 
 (c) The amount paid by an indemnifying party or payable to an indemnified party

  

 9 








 
as a result of the losses, claims, damages and liabilities referred to in this Section 5 shall be deemed to include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim, payable as the same are incurred. The indemnification and contribution provided for in this Section 5 will remain in full
force and effect regardless of any investigation made by or on behalf of the indemnified parties or any officer, director, employee, agent or controlling person of the indemnified parties. No indemnifying party, in the defense of any such claim or
litigation, shall enter into a consent of entry of any judgment or enter into a settlement without the consent of the indemnified party, which consent will not be unreasonably withheld. 
 6. Rule 144 and Rule 144A Requirement. In the event that the Company becomes subject to Section 13 or Section 15(d)
of the Exchange Act, the Company shall use its best efforts to take all action as may be required as a condition to the availability of Rule 144 or Rule 144A under the Securities Act (or any successor or similar exemptive rules hereafter in effect).
The Company shall furnish to any Holder, within 15 days of a written request, a written statement executed by the Company as to the steps it has taken to comply with the current public information requirement of Rule 144 or Rule 144A or such
successor rules. 
 7. Transferability of Registration Rights. The registration rights set forth in this Agreement
are transferable to any transferee of Registrable Securities who receives any shares of Registrable Securities. Each subsequent holder of Registrable Securities must consent in writing to be bound by the terms and conditions of this Agreement in
order to acquire the rights granted pursuant to this Agreement. 
 8. Rights Which May Be Granted to
Subsequent Investors. Other than transferees of Registrable Securities under Section 7 hereof, the Company shall not, without the prior written consent of the Investors holding at least sixty-six and two-thirds percent (66 2/3%) of the outstanding Series A Preferred Stock, Series
B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred Stock (voting together as a single class and on an as-converted basis), grant any other registration rights to any third parties. 
 9. Miscellaneous. 
 (a) Amendments. For the purposes of this Agreement and all agreements executed pursuant hereto, no course of dealing between or among any of the parties hereto and no delay on the part of
any party hereto in exercising any rights hereunder or thereunder shall operate as a waiver of the rights hereof and thereof. This Agreement may not be amended or modified or any provision hereof waived without the joint written consent of the
Company and the Investors holding at least sixty-six and two-thirds percent (66 2/3%) of the Registrable Securities attributable to the conversion of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred Stock;
provided, however, that (i) in the event that any amendment, modification or waiver under this Agreement treats the Series 1 Holders in an adverse manner that is different from the Investors vis a vis their rights hereunder, such
amendment, modification or waiver shall also require the written consent of Series 1 Holders holding at least a majority of the Registrable Securities attributable to the conversion of the Series 1 Preferred Stock, (ii) in the event that any
amendment, modification or waiver under this Agreement treats the MBI Group Holders in an

  

 10 








 
adverse manner that is different from the Investors vis a vis their rights hereunder, such amendment, modification or waiver shall also require the written consent of the MBI Group Holders
holding at least a majority of the Registrable Securities held by the MBI Group Holders, (iii) in the event that any amendment, modification or waiver under this Agreement treats the LRG Holders in an adverse manner that is different from the
Investors vis a vis their rights hereunder, such amendment, modification or waiver shall also require the written consent of the LRG Holders holding at least a majority of the Registrable Securities held by the LRG Holders, (iv) in the event
that any amendment, modification or waiver under this Agreement treats the Strategic Investor in an adverse manner that is different from the Investors vis a vis their rights hereunder, such amendment, modification or waiver shall also require the
written consent of the Strategic Investor and (v) notice of any amendment, modification or waiver under this Agreement shall be delivered to the Series 1 Representatives and the MBI Group Holder Representative (each in the manner set forth
below). 
 (b) Notices and Demands. Any notice or demand which, by any provision of this Agreement or any
agreement, document or instrument executed pursuant hereto or thereto, except as otherwise provided therein, is required or provided to be given shall be deemed to have been sufficiently given or served and received for all purposes when delivered

 (c) Dispute
Resolution. 
 (i) All disputes, claims or controversies arising out of or relating to this Agreement or any
other agreement executed and delivered pursuant to this Agreement or the negotiation, validity or performance hereof and thereof or the transactions contemplated hereby and thereby that are not resolved by mutual agreement shall be resolved solely
and exclusively by binding arbitration to be conducted before the American Arbitration Association (“AAA”). If AAA ceases operation, then the parties shall select a comparable organization that provides qualified arbitration
services. The arbitration shall be held in Boston, Massachusetts before a single arbitrator and shall be conducted in accordance with the rules and regulations promulgated by AAA unless specifically modified herein. 
 The parties covenant and agree that the arbitration hearing shall commence within ninety (90) days of the date on which a written
demand for arbitration is filed by any party hereto. In connection with the arbitration proceeding, the arbitrator shall have the power to order the production of documents by each party and any third-party witnesses. In addition, each party may
take up to three depositions as of right, and the arbitrator may in his or her discretion allow additional depositions upon good cause shown by the moving party. However, the arbitrator shall not have the power to order the answering of
interrogatories or the response to requests for admission. In connection with any arbitration, each party shall provide to the other, no later than seven (7) business days before the date of the arbitration hearing, the identity of all persons
that may testify at the arbitration and a copy of all documents that may be introduced at the arbitration hearing or considered or used by a party’s witness or expert. The arbitrator’s decision and award shall be made and delivered within
three (3) months of the selection of the arbitrator.

  

 12 








 
The arbitrator’s decision shall set forth a reasoned basis for any finding of liability or award of damages. The arbitrator shall not have power to award damages in excess of actual
compensatory damages and shall not multiply actual damages or award punitive damages or any other damages that are specifically excluded under this Agreement, and each party hereby irrevocably waives any claim to such damages. 
 The parties covenant and agree that they will participate in the arbitration in good faith and that they will share equally its costs,
except as otherwise provided herein. The arbitrator may in his or her discretion assess costs and expenses (including the reasonable legal fees and expenses of the prevailing party) whether claimant or respondent against any party to a proceeding.
Any party failing or refusing to comply with an order of the arbitrators shall be liable for costs and expenses, including attorneys’ fees, incurred by the other party in enforcing the award. Nothing in this Section 9(c) shall prohibit any
party from proceeding in court without prior arbitration for the limited purpose of seeking a temporary or permanent injunction to avoid immediate and irreparable harm. The provisions of this Section 9(c) shall be enforceable in any court of
competent jurisdiction. 
 Unless otherwise ordered, the parties shall bear their own attorneys’ fees, costs and expenses
in connection with the arbitration. The parties will share equally in the fees and expenses charged by AAA. 
 (ii) Each
of the parties hereto irrevocably and unconditionally consents to the exclusive use of AAA to resolve all disputes, claims or controversies arising out of or relating to this Agreement or any other agreement executed and delivered pursuant to this
Agreement or the negotiation, validity or performance hereof and thereof or the transactions contemplated hereby and thereby and further consents to the jurisdiction of the courts of The Commonwealth of Massachusetts for the purposes of enforcing
the arbitration provisions of Section 9(c)(i) of this Agreement. Each party further irrevocably waives any objection to proceeding before AAA based upon lack of personal jurisdiction or to the laying of venue and further irrevocably and
unconditionally waives and agrees not to make a claim in any court that arbitration before AAA has been brought in an inconvenient forum. Each of the parties hereto hereby consents to service of process by registered mail at the address to which
notices are to be given. Each of the parties hereto agrees that its, his or her submission to jurisdiction and its, his or her consent to service of process by mail is made for the express benefit of the other parties hereto. 
 (d) Remedies; Severability. Notwithstanding Section 9(c), it is specifically understood and agreed that any breach of the
provisions of this Agreement by any Person subject hereto will result in irreparable injury to the other parties hereto, that the remedy at law alone will be an inadequate remedy for such breach, and that, in addition to any other remedies which
they may have, such other parties may enforce their respective rights by actions for specific performance (to the extent permitted by law). Whenever possible, each provision of this Agreement shall be interpreted in such a manner as to be effective
and valid under applicable law, but if any provision of this Agreement shall be deemed prohibited or invalid under such applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, and such prohibition or
invalidity shall not invalidate the remainder of such provision or the other provisions of this Agreement.

 (e) Counterparts. This Agreement may be executed in multiple
counterparts, each of which shall constitute an original but all of which shall constitute but one and the same instrument. One or more counterparts of this Agreement may be delivered via telecopier, with the intention that they shall have the same
effect as an original counterpart hereof. 
 (f) Effect of Heading. The Section headings herein are for
convenience only and shall not affect the construction hereof. 
 (g) Governing Law. This Agreement shall be
deemed a contract made under the laws of the State of Delaware and together with the rights and obligations of the parties hereunder, shall be construed under and governed by the laws of the State of Delaware, without giving effect to its conflicts
of laws principles. 
 (h) Assignment. This Agreement shall be binding upon and shall inure to the benefit of the
parties hereto and their respective heirs, executors, legal representatives, successors, permitted assigns and transferees, except as may be expressly provided otherwise herein. Notwithstanding anything to the contrary contained herein, (a) an
Investor may assign any of its rights under this Agreement to any Affiliate (as defined in that certain Series E Preferred Stock Agreement dated as of May 4, 2007) of such Investor, (b) a Series 1 Holder may assign any of its rights under
this Agreement to another person party to that certain Deed of Contribution among, inter alia, J.S. Rabbetts and others, (c) an LRG Holder may assign any of its rights under this Agreement in accordance with the Loan Agreement and (d) the
Strategic Investor may assign any of its rights under this Agreement in accordance with the Purchase Agreement. 
 (i)
Integration. This Agreement, including the exhibits, documents and instruments referred to herein or therein, constitutes the entire agreement, and supercedes all other prior agreements and understandings, both written and oral,
among the parties with respect to the subject matter hereof. In accordance with Section 9(a) of the Prior Agreement, the Company and the Investors hereby agree that this Agreement amends, restates and supercedes the Prior Agreement in its
entirety and that the Prior Agreement is hereafter null and void.
