the granting of certain registration rights to the Holders (as defined below) relating to the Common Stock held and the Common Stock issuable upon conversion or exercise of the Securities, as applicable, by such Holders. 

NOW, THEREFORE, the parties hereby agree as follows: 
 AGREEMENT: 
 The parties hereto agree as follows: 

1. Certain Definitions. As used in this Agreement, the following terms shall have the following respective meanings: 

“Commission” shall mean the U.S. Securities and Exchange Commission. 

“Exchange Act” shall mean the U.S. Securities Exchange Act of 1934, as amended, and the rules and regulations of the
Commission promulgated thereunder, all as the same shall be in effect from time to time. 

  
 1. 









 “Holders” or “Holders of Registrable Securities” shall
mean EIS, EPIL and any Person who shall have acquired Registrable Securities from EIS or EPIL as permitted herein, either individually or jointly, as the case may be, in a transaction pursuant to which registration rights are transferred pursuant to
Section 10 hereof. 
 “Person” shall mean an individual, a partnership, a corporation, a limited liability
company, an association, a joint stock company, a trust, a joint venture, an unincorporated organization or a governmental or quasi-governmental entity, or any department, agency or political subdivision thereof or any other entity of any kind.

 “Registrable Securities” means (i) any shares of Common Stock subscribed for pursuant to the Purchase
Agreement; (ii) any shares of Common Stock issued or issuable upon conversion or exercise of the Securities, as the case may be; and (iii) any shares of Common Stock issued or issuable in respect of the securities referred to in clauses
(i) and (ii) above, whether to satisfy interest or dividend payments or upon any stock split, dividend, recapitalization or otherwise, until, in the case of any such security, it is (A) sold pursuant to an effective registration
statement under the Securities Act; (B) eligible to be sold into the public market without regard to volume limitations under Rule 144(k) promulgated under the Securities Act (or any successor rule); (C) sold pursuant to Rule 144 under the
Securities Act (or any successor rule); or (D) sold by a Person in a transaction in which registration rights are not transferred pursuant to Section 10 hereof. Whenever a number or percentage of Registrable Securities is to be determined
pursuant to this Agreement, each then outstanding Security that is convertible into or exercisable for shares of Common Stock will be deemed to be equal to the number of shares of Common Stock for which such Security is then so convertible or
exercisable. 
 The terms “register,” “registered” and “registration” refer
to a registration effected by preparing, filing and having declared effective a registration statement in compliance with the Securities Act. 
 “Registration Expenses” shall mean (i) all expenses, other than Selling Expenses (defined below), incurred by the Company in complying with Sections 2 or 3 hereof, including without
limitation, all registration, qualification and filing fees, exchange or quotation medium listing fees, printing and delivery expenses, escrow and custodian fees, fees and disbursements of counsel for the Company, blue sky fees and expenses and the
expenses of accountants for the Company including the expenses of any special audits incident to or required by any such registration and (ii) the reasonable fees and disbursements of one counsel chosen by the holders of a majority of the
Registrable Securities included in such registration for the purpose of rendering a legal opinion on behalf of such holders in connection with any Demand Registration or Piggyback Registration, provided however, that if the aggregate expense of such
counsel exceeds U.S. $25,000 such excess expense shall be borne by such holders. 
 “Securities Act” shall mean
the U.S. Securities Act of 1933, as amended, and the rules and regulations of the Commission promulgated thereunder, all as the same shall be in effect from time to time. 

  
 2. 









 “Selling Expenses” shall mean all underwriting discounts, selling
commissions and stock transfer taxes and the costs, fees and expenses of any accountants, attorneys (other than the cost, fees and expenses of attorneys which are Registration Expenses) or other experts retained by the Holders. 

2. Demand Registrations. 
 (a) Requests for Registration. At any time after the six-month anniversary of the earlier of (i) the date of effectiveness of a registration statement filed under the Securities Act in respect
of an initial public offering of shares of Common Stock of the Company and (ii) the date the Company or a successor corporation is first obligated to file reports with the Commission pursuant to Section 12 or Section 15(d) of the
Exchange Act, any Holder or Holders who collectively hold Registrable Securities representing at least 5% of the Registrable Securities then outstanding shall have the right (subject to the limitations set forth below), exercisable by written notice
to the Company (each a “Registration Request”), to have the Company prepare and file with the Commission a registration statement under the Securities Act covering the Registrable Securities that are the subject of such request
(each, a “Demand Registration”). A request for a Demand Registration shall specify the approximate number of the Registrable Securities to be registered, which, in the case of a registration on Form S-1 or any successor form, must
have a minimum expected aggregate offering price to the public of at least U.S. $2,500,000, or, in the case of a registration on Form S-3 or any successor form, must have a minimum expected aggregate offering price to the public of at least U.S.
$1,000,000. Within 10 days after receipt of any such request, the Company will give written notice of such requested registration to all other Holders of Registrable Securities. The Company shall include such other Holders’ Registrable
Securities in such offering if they have responded affirmatively within 10 days after the receipt of the Company’s notice. The Investors shall be permitted one Demand Registration hereunder. Notwithstanding the foregoing, so long as the Company
is entitled to use Form S-3 under the Securities Act, the Holders, collectively, shall be permitted unlimited Demand Registrations hereunder on Form S-3, or any similar short-form registration (a “Short-Form Registration”), if
available; provided that the Holders, collectively, will be entitled to request only one Short-Form Registration in any 12-month period. For purposes of this Section 2, the term Registrable Securities, notwithstanding its definition in
Section 1 of this Agreement, shall not include shares of the Common Stock issuable upon conversion of shares of the Series A Preferred Stock.1 
 A request
for registration under this Section 2(a) will not count as a Demand Registration until the registration statement has become effective and remained effective until the earlier of 30 days and the sale of all securities registered thereunder
(unless such registration statement has not become effective due solely to the actions or failure to act with respect to such registration of the Holders requesting such registration, including a request by such Holders that such registration be
withdrawn). 
  

	1 	The last two sentences of this section 2(a) were added to this agreement pursuant to that certain Termination Agreement, dated December 23, 2003, by and among the
Company, EIS, EPIL, Elan Corporation, Plc., and LC Ventures, Ltd. 


  
 3. 









 (b) Priority on Demand Registrations. If a Demand Registration is an underwritten
offering and the managing underwriters advise the Company in writing that in their opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such offering, exceeds the number of
Registrable Securities and other securities, if any, which can be sold in such offering without adversely affecting the marketability of the offering, the Company will include in such registration: 

(i) first, the Registrable Securities requested to be included in such registration by the Holders (or, if necessary, such
Registrable Securities pro rata among the Holders thereof based upon the number of Registrable Securities owned by each such Holder or such other arrangement agreed to among the Holders); and 

(ii) thereafter, other securities requested to be included in such registration, as determined by the Company. 

The Holders of any Registrable Securities to be included in such an underwritten offering shall enter into an underwriting agreement (which shall be in
customary form, may include agreements as to indemnification and contribution and shall provide that the representations and warranties by the Company to and for the benefit of such underwriters, shall also be made to and for the benefit of such
Holders) and in form and substance satisfactory to the managing underwriters and Holders. If any Holder does not agree to the terms of any such underwriting agreement, which agreement shall be in reasonable and customary form, such Holder shall be
excluded from the underwriting upon written notice thereof from the Company or the underwriter. 
 (c) Restrictions on Demand
Registration. The Company may postpone or suspend, for up to 90 days in any 12-month period, the filing or the effectiveness of a registration statement for a Demand Registration if the Company’s board of directors determined in good faith
and notifies the Holders in writing that such Demand Registration (i) would reasonably be expected to have a material adverse effect on (x) any proposal or plan by the Company to engage in any financing, acquisition or disposition of
assets (other than in the ordinary course of business) or (y) any merger, consolidation, tender offer or similar transaction or (ii) would require disclosure of any information that the board of directors of the Company determines in good
faith the disclosure of which would be detrimental to the Company; provided, however, that in such event, the Holders initially requesting such Demand Registration (the “Initiating Holders”) shall be entitled to
withdraw such request and, if such request is withdrawn, such Demand Registration will not count as a permitted Demand Registration hereunder and the Company will pay any Registration Expenses in connection with such registration. 

(d) Selection of Underwriter. The underwriter will be selected by the Company and shall be reasonably acceptable to a majority in
interest of the Initiating Holders. 
 (e) The Company represents and warrants that it is not a party to, or otherwise
subject to, any agreement, other than this Agreement, granting registration rights to any other Person with respect to any securities of the Company. 

  
 4. 









 (f) Limitations on Registration. The Company shall not be obligated to effect, or
take any action to effect, any registration pursuant to this Section 2: 
 (i) in any jurisdiction in which the
Company would be required to execute a general consent to service of process in effecting such registration, qualification or compliance, unless the Company is already subject to service of process in such jurisdiction and except as may be required
by the Securities Act; 
 (ii) after the Company has initiated one such registration pursuant to this Section 2;
and 
 (iii) during the period commencing on the filing of a registration statement (provided that the Company complied
with the provisions in Section 3a hereof with respect to such registration) and ending on a date 90 days after the effective date of a Company initiated registration; provided that the Company is actively employing reasonable efforts to cause
such registration statement to become effective. 
 3. Piggyback Registrations. 

(a) Right to Piggyback. If at any time the Company shall propose to register shares of Common Stock under the Securities Act (other
than the Company’s initial public offering and in a registration statement relating to solely to sales of securities to participants in a Company dividend reinvestment plan, or Form S-4 or S-8 or any successor form or in connection with an
acquisition or exchange offer or an offering of securities solely to the existing shareholders or employees of the Company), the Company (i) will give prompt written notice to all Holders of Registrable Securities of its intention to effect
such a registration and (ii) subject to Section 3(b) and the other terms of this Agreement, will include in such registration all Registrable Securities which are permitted under applicable securities laws to be included in the form of
registration statement selected by the Company and with respect to which the Company has received written requests for inclusion therein within 30 days after the receipt of the Company’s notice (each, a “Piggyback
Registration”). The Holders will be permitted to withdraw all or any part of the Registrable Securities from a Piggyback Registration at any time prior to the effective date of such Piggyback Registration. 

(b) Priority on Piggyback Registrations. If a Piggyback Registration is to be an underwritten offering, and the underwriter
advises the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability of the offering, the
Company will include in such registration: 
 (i) first, the securities the Company proposes to sell for its own account;

 (ii) second, the Registrable Securities requested .to be included in such registration by the Holders and any
securities requested to be included in such registration by any other Person pursuant to a demand registration request, other than Persons having a lower priority of registration than the Holders, pro rata among the Holders of such Registrable
Securities and such other Persons, on the basis of the number of securities requested to be included in such registration by each of such Holders and such other Persons; and 

  
 5. 









 (iii) thereafter, other securities requested to be included in such registration, as
determined by the Company. 
 The Holders of any Registrable Securities to be included in an underwritten offering shall enter into an
underwriting agreement (which shall be in customary form, may include agreements as to indemnification and contribution, and shall provide that the representations and warranties by the Company to and for the benefit of such underwriters, shall also
be made to and for the benefit of such Holders). If any Holder does not agree to the terms of any such underwriting agreement, which agreement shall be in reasonable and customary form, such Holder shall be excluded from the underwriting upon
written notice thereof from the Company or the underwriter. 
 (c) Right to Terminate Registration. If at any time after
giving written notice of its intention to register any of its securities as set forth in Section 3(a) and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any
reason not to register such securities, the Company may, at its election, give written notice of such determination to each Holder of Registrable Securities and thereupon 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 in connection therewith as provided herein). 
 (d) Selection of Underwriters/Placement Agents. The Company will have the right in its sole discretion, to select the underwriter for a Piggyback Registration. 

4. Expenses of Registration. 
 Except as otherwise provided herein or as may otherwise be prohibited by applicable law, all Registration Expenses incurred in connection with all registrations pursuant to Sections 2 and 3 hereof shall
be borne by the Company provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Sections 2 unless (a) the withdrawal is based upon material adverse information
concerning the market for the Company’s securities or the Company of which the Holders were not aware or which did not exist at the time of such request or (b) the Holders of a majority of Registrable Securities agree to forfeit their
right to one requested registration pursuant to Section 2, in which event such right shall be forfeited by all Holders. If the Holders are required to pay the Registration Expenses, such expenses shall be borne by the holders of the securities
(including Registrable Securities) requesting such registration in proportion to the number of shares for which registration was requested. If the Company is required to pay the Registration Expenses of a withdrawn offering pursuant to clause
(a) above, then the Holders shall not forfeit their rights pursuant to Section 2 to a demand registration. All Selling Expenses relating to securities registered on behalf of the Holders of Registrable Securities shall be borne by such
Holders. 

  
 6. 









 5. Holdback Agreements. 

(a) The Company agrees (i) not to effect any public sale or distribution of its equity securities, or any securities
convertible into or exchangeable or exercisable for such securities, during the 10-day period prior to, and during the 90-day period following, the effective date of any underwritten Demand Registration or any underwritten Piggyback Registration
(except as part of such underwritten registration or pursuant to registration statements on Form S-4 or Form S-8 or any successor form), unless the underwriters managing the offering otherwise agree, and (ii) to use its best efforts to cause
its officers and directors and each holder of at least 1% (on a fully-diluted basis) of its outstanding shares of Common Stock, or any securities convertible into or exchangeable or exercisable for shares of Common Stock, purchased from the Company
at any time after the date of this Agreement (other than in a registered public offering) to agree not to effect any public sale or distribution (including sales pursuant to Rule 144) of any such securities during such periods (except as part of
such underwritten registration, if otherwise permitted), unless the underwriters managing the registered public offering otherwise agree. 
 (b) If requested by the managing underwriter(s) in an underwritten offering of Common Stock or securities convertible for Common Stock of the Company (including without limitation the
Company’s initial public offering of Common Stock), each Holder agrees, unless such holder is a participant in such offering, not to sell, make any short sale of, loan, hypothecate, pledge, grant any option for the purchase of, including a sale
pursuant to Rule 144 (or any similar provision then in effect) under the Securities Act (except as part of such underwritten, registration) or otherwise dispose or transfer for value or otherwise agree to engage in any of the foregoing transactions
with respect to any securities of the Company held by such party without the prior written consent of the Company and its managing underwriters, during the 10-day period prior to, and during the 180-day period after in the case of the Company’s
initial public offering, if applicable, or the 90-day period in the case of any other public offering of Common Stock (or, in each case, such shorter period as may be agreed to in writing by the Company and the Holders of at least 50% of the
Registrable Securities) following, the effective date of such Registration Statement; provided, however, that (i) no Holder shall be required to enter into more than one such agreement in any 12-month period unless the offering
pursuant to which such agreement is requested is determined by the Holders to be a good faith offering and not for the purpose of restricting or prohibiting the exercise of the Holders rights hereunder, and (ii) no Holder shall be required to
enter into such an agreement unless all Persons entitled to registration rights who are not parties to this Agreement, all other Persons selling shares in such offering, all Persons holding at least I% (on a fully diluted basis) of the
Company’s outstanding shares of Common Stock (other than that purchased in a registered public offering) and all executive officers and directors of the Company shall also have agreed not to offer, sell, distribute a transfer under the
circumstances and pursuant to the terms set forth in this Section 5(b). 
 6. Registration Procedures. 

Whenever the Holders of Registrable Securities have requested that any Registrable Securities be registered pursuant to this Agreement,
the Company will use its best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method or methods of distribution thereof, and pursuant thereto the Company will under the time frames
provided herein, or if not so provided, as expeditiously as possible: 

  
 7. 









 (a) prepare and file with the Commission a registration statement on any appropriate
form for which the Company qualifies with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective (provided that before filing a registration statement or prospectus or any
amendments or supplements thereto, the Company will (i) furnish to the counsel selected by the Holders copies of all such documents proposed to be filed, which documents will be subject to the review of such counsel and the review and approval
of such counsel only with respect to the portions of the documents which refer to the Holders or the method of distribution of the Registrable Securities, and (ii) notify each Holder of Registrable Securities covered by such registration of any
stop order issued or threatened by the Commission); 
 (b) prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection therewith as may be reasonably necessary to keep such registration statement effective for a period equal to the shorter of (i) six months and (ii) the time
by which all securities covered by such registration statement have been sold, and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during such period in
accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement; 
 (c)
furnish to each seller of Registrable Securities such number of copies of such registration statement, each amendment and supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus) and such
other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller; 
 (d) use all reasonable efforts to register or qualify such Registrable Securities under the securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all
other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller (provided that the Company will not be required
to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 6(d), (ii) subject itself to taxation in any jurisdiction or (iii) take any action that would
subject it to general service of process in any such jurisdiction); 
 (e) promptly notify each seller of such
Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue
statement of a material fact or omits any material fact necessary to make the statements therein not misleading, and, the Company will prepare and deliver to each Holder a supplement or amendment to such prospectus so that, as thereafter delivered
to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading; provided, however,
that the Company shall be required to notify the Holders, but shall not be required to amend the registration statement or supplement the Prospectus for a period of up to three months if the board of directors determines in good faith that to do so
would reasonably be expected to have a material adverse effect on any proposal or plan by the 

  
 8. 









 
Company to engage in any financing, acquisition or disposition of assets (other than in the ordinary course of business) or any merger, consolidation, tender offer or similar transaction or would
require the disclosure of any information that the board of directors determines in good faith the disclosure of which would be materially detrimental to the Company, it being understood that the period for which the Company is obligated to keep the
Registration Statement effective shall be extended for a number of days equal to the number of days the Company delays amendments or supplements pursuant to this provision. Upon receipt of any notice pursuant to this Section 6(e), the Holders
shall suspend all offers and sales of securities of the Company and all use of any prospectus until advised by the Company that offers and sales may resume, and shall keep confidential the fact and content of any notice given by the Company pursuant
to this Section 6(e); 
 (f) cause all such Registrable Securities to be listed on each securities exchange or
quoted on Nasdaq or other quotation medium, if any, on which similar securities issued by the Company are then listed or quoted; 
 (g) provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of such registration statement; 

(h) enter into such customary agreements (including underwriting agreements in customary form) and take all such other actions as
the Holders of a majority of the Registrable Securities being sold or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities (including effecting a stock split or a combination
of shares); 
 (i) make available for inspection by the Holders of Registrable Securities included in the registration
statement, any underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other agent retained by any such seller or underwriter, all pertinent financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent
in connection with such registration statement and (ii) to participate in presentations to prospective purchasers as reasonably requested by any underwriter or placement agent; 

(j) otherwise use its best efforts to comply with all applicable rules and regulations of the Commission, and make available to
its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the
registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder; 
 (k) in the event of the issuance of any stop order suspending the effectiveness of a registration statement, or of any order suspending or preventing the use of any related prospectus or suspending
the qualification of any shares of Common Stock included in such registration statement for sale in any jurisdiction, use its best efforts promptly to obtain the withdrawal of such order; 

  
 9. 









 (l) if the registration statement is an underwritten offering, use all reasonable
efforts to obtain a so-called “cold comfort” letter from the Company’s independent public accountants in customary form and covering such matters of the type customarily covered by cold comfort letters; 

(m) use its best efforts to cause such Registrable Securities covered by such registration statement to be registered with or
approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Registrable Securities; and 
 (n) If any such registration or comparable statement refers to any Holder by name or otherwise as the holder of any securities of the Company and if in its sole and exclusive judgment, such Holder
is or might be deemed to be an underwriter or a controlling person of the Company, such Holder shall have the right to require (i) the insertion therein of language, in form and substance satisfactory to such Holder and presented to the Company
in writing, 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 shall assist in meeting any future financial requirements of the Company, or (ii) in the event that such reference to such Holder by name or otherwise is not required by the Securities Act or any similar Federal statute then in
force, the deletion of the reference to such Holder; provided that with respect to this clause (ii) such Holder shall (a) furnish to the Company an opinion of counsel to such effect, which opinion and counsel shall be reasonably
satisfactory to he Company and (b) indemnify the Company against any loss or liability imposed upon and any reasonable expenses incurred by the Company as a result of such deletion. 

7. Obligations of Holders. 
 Whenever the Holders of Registrable Securities sell any Registrable Securities pursuant to a Demand Registration or a Piggyback Registration, such Holders shall be obligated to comply with the applicable
provisions of the Securities Act, including the prospectus delivery requirements thereunder, and any applicable state securities or blue sky laws. In addition, each Holder of Registrable Securities will be deemed to have agreed by virtue of its
acquisition of such Registrable Securities that, upon receipt of any notice described in Section 6(e), such Holder will forthwith discontinue disposition of such Registrable Securities covered by such registration statement or prospectus until
such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 6(e), or until it is advised in writing by the Company that the use of the applicable prospectus may be resumed, and has received copies
of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such prospectus. 

8. Indemnification. 
 (a) The Company agrees to indemnify, to the fullest extent permitted by applicable law, each Holder of Registrable Securities, its officers and directors and each Person who controls such Holder
(within the meaning of the Securities Act) against all losses, claims, damages, liabilities, expenses or any amounts paid in settlement of any litigation, investigation or 

  
 10.









 
proceeding commenced or threatened (collectively, “Claims”) to which each such indemnified party may become subject under the Securities Act insofar as such Claim arose out of
(i) any untrue or alleged untrue statement of material fact contained, in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or (ii) 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, ((i) and (ii) collectively, a “Violation”), provided however, that the indemnity agreement contained in this
Section 8 shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld or delayed), nor
shall the Company be liable in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a Violation which occurs solely in reliance upon and in conformity with any information
furnished in writing to the Company by such Holder expressly for use therein, or by such Holder’s failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished
such Holder with a sufficient number of copies of the same. In connection with an underwritten offering, the Company will indemnify the underwriters, their officers and directors and each Person who controls the underwriters (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. 
 (b) In connection with any registration statements in which a Holder of Registrable Securities is participating, each such Holder will, to the fullest extent permitted by applicable law, indemnify
the Company, its directors and officers and each Person who controls the Company (within the meaning of the Securities Act) against any and all Claims to which each such indemnified party may become subject under the Securities Act insofar as such
Claim arose out of (i) any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto, (ii) 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; provided that with respect to a Claim arising pursuant to clause (i) or (ii) above, the material
misstatement or omission is contained in the information such Holder provided to the Company pursuant to Section 11 hereof; provided, further, that the obligation to indemnify will be individual to each Holder and will be limited to the amount
of proceeds received by such Holder from the sale of Registrable Securities pursuant to such registration statement. In connection with an underwritten offering, each Holder will indemnify the underwriters (within the meaning of the Securities Act)
to the same extent as provided above with respect to the indemnification of the Company hereunder. 
 (c) Any Person
entitled to indemnification hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (but the failure to provide such notice shall not release the indemnifying party of
its obligation under paragraphs (a) and (b), unless and then only to the extent that, the indemnifying party has been prejudiced by such failure to provide such notice) and (ii) unless in such indemnified party’s reasonable judgment,
based on written advice of counsel, a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. An indemnifying party who is not entitled to, or elects not 

  
 11.









 
to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim,
unless in the reasonable judgment of any indemnified party, based on written advice of counsel, a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. 

(d) The indemnifying party shall not be liable to indemnify an indemnified party for any settlement, or consent to judgment of any
such action effected without the indemnifying party’s written consent (but such consent will not be unreasonably withheld, delayed or conditioned). Furthermore, the indemnifying party shall not, except with the prior written approval of each
indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to each indemnified party of a release from all liability in respect of
such claim or litigation without any payment or consideration provided by each such indemnified party. 
 (e) If the
indemnification provided for in this Section 8 is unavailable to an indemnified party under clauses (a) and (b) above in respect of any losses, claims, damages or liabilities referred to therein, then each 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 losses, claims, damages or liabilities in such proportion as is appropriate to reflect not only the relative
benefits received by the Company, the underwriters, the sellers of Registrable Securities and any other sellers participating in the registration statement from the sale of shares pursuant to the registered offering of securities for which indemnity
is sought but also the relative fault of the Company, the underwriters, the sellers of Registrable Securities and any other sellers participating in the registration statement in connection with the misstatement or omission which resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, the underwriters, the sellers of Registrable Securities and any other sellers participating in the
registration statement shall be deemed to be based on the relative relationship of the total net proceeds from the offering (before deducting expenses) to the Company, the total underwriting commissions and fees from the offering (before deducting
expenses) to the underwriters and the total net proceeds from the offering (before deducting expenses) to the sellers of Registrable Securities and any other sellers participating in the registration statement. The relative fault of the Company, the
underwriters, the sellers of Registrable Securities and any other sellers participating in the registration statement 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 or by the sellers of Registrable Securities and the parties’ relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission; provided that in no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the proceeds received by such Holder upon the sale of the Registrable Securities
giving rise to such indemnification obligation. 
 (f) The indemnification provided for wider this Agreement will remain
in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and will survive the transfer of the Registrable Securities.

 9. Participation in Underwritten Registrations. 

No Person may participate in any registration hereunder which is underwritten unless such Person (a) agrees to sell such
Person’s securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney,
indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements; provided that no Holder of Registrable Securities included in any underwritten registration shall be required to
make any representations or warranties to the Company or the underwriters (other than representations and warranties regarding such Holder and such Holder’s intended method of distribution) or to undertake any indemnification obligations to the
Company or the underwriters with respect thereto, except as otherwise provided in paragraph 8 hereof. 
 10. Transfer of
Registration Rights. 
 The rights granted to any Holder under this Agreement may be assigned to any Person in connection
with any transfer or assignment of Registrable Securities by a Holder; provided, however, that: (a) such transfer is otherwise effected in accordance with applicable securities laws, (b) such transfer is not in violation of
the Purchase Agreement, (c) if not already a party hereto, the assignee or transferee agrees in writing prior to such transfer to be bound by the provisions of this Agreement and, (d) unless otherwise notified by the Holder, EIS shall act
as agent and representative for such Holder for the giving and receiving of notices hereunder. 
 11. Information by Holder.

 Each Holder shall furnish to the Company such written information regarding such Holder and any distribution proposed by
such Holder as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Agreement and shall promptly notify the Company of any changes in
such information. 
 12. Exchange Act Compliance. 

The Company shall comply with all of the reporting requirements of the Exchange Act then applicable to it, if any, and shall comply with
all other public information reporting requirements of the Commission which are conditions to the availability of Rule 144 for the sale of the Registrable Securities. The Company shall cooperate with each Holder in supplying such information as may
be necessary for such Holder to complete and file any information reporting forms presently or hereafter required by the Commission as a condition to the availability of Rule 144. 

13. Termination of Registration Rights. 
 All registration rights and obligations under this Agreement shall terminate and be of no further force and effect, as to any particular Holder, at such time as all Registrable Securities held by such
Holder are eligible to be sold without compliance with the registration rights of the Securities Act, without any volume or timing restrictions pursuant to Rule 144(k), promulgated thereunder or have been sold pursuant to a registration statement
thereunder. 

  
 13.









 14. Miscellaneous. 

(a) No Inconsistent Agreements. So long as any Holder owns any Registrable Securities, the Company will not (i) enter into any
agreement that is inconsistent with or violates the rights granted hereunder to the Holders of Registrable Securities, including, without limitation, any agreement that would require the Company to register any of its securities with priority with
respect to registration over, the rights granted to the Holders hereunder, without the prior written consent of the Holders of at least 50% of the Registrable Securities or (ii) register for sale in a public offering any shares of capital stock
of the Company other than the Common Stock. 
 (b) Remedies. Any Person having rights under any provision of this
Agreement will be entitled to enforce such rights specifically to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction (without posting any bond or other security) for
specific performance and for other injunctive relief in order to enforce or prevent violation of the provisions of this Agreement; provided, however, that in no event shall any Holder have the right to enjoin, delay or interfere with
any offering of securities by the Company. 
 (c) Amendments and Waivers. Except as otherwise provided herein, the
provisions of this Agreement may be amended or waived only with the prior written consent of the Company and Holders of at least 50% of the Registrable Securities; provided, however, that without the prior written consent of all the
Holders, no such amendment or waiver shall reduce the foregoing percentage required to amend or waive any provision of this Agreement. 
 (d) Successors and Assigns. This Agreement and all of the provisions hereof shall be binding, upon and inure to the benefit of the parties and their respective successors and permitted assigns.
Unless an express assignment has been made, the provisions of this Agreement which are for the benefit of Holders of Registrable Securities are also for the benefit of, and enforceable by, any transferee of Registrable Securities, in accordance with
Section 10 hereof. 
 (e) Severability. In case any provision of this Agreement shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not be in any way affected or impaired thereby. 
 (f) Counterparts and Facsimile. This Agreement may be executed in any number of counterparts, and each such counterpart hereof shall be deemed to be an original instrument, but all such
counterparts together shall constitute one agreement. This Agreement may be signed and delivered to the other party by facsimile transmission; such transmission shall be deemed a valid signature. 

  
 14.









 (g) Descriptive Headings. The section and paragraph headings contained in this
Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. 

(h) Governing Law; Disputes. This Agreement shall be governed by and construed in accordance with the internal laws of the State
of New York, without giving effect to conflicts of laws rules or principles. Any dispute under this Agreement that is not settled by mutual consent shall be finally adjudicated by any federal or state court sitting in the City, County and State of
New York or in the City and State of Salt Lake City, Utah, and each party consents to the non-exclusive jurisdiction of such courts (or any appellate court therefrom) over any such dispute.
