 RECITALS 

WHEREAS, this Agreement is made in connection with (1) the closing of the transactions contemplated by the Agreement and Plan of Merger
(the “Merger Agreement”), dated as of September 2, 2016, by and among Parent, ERI Holdings III, Inc., a New Mexico corporation and wholly owned subsidiary of Parent (“Merger Sub”), and MYCO

WHEREAS, Parent has agreed to provide the registration and other rights set forth in this Agreement for the benefit of the Company
Stockholders who will receive Subject Common Stock on the Closing Date as the Merger Consideration. 
 NOW, THEREFORE, in consideration of

ARTICLE I 

REGISTRATION RIGHTS 

Section 1.01 Shelf Registration. 

(a) Shelf Registration. Parent shall (i) prepare and file a registration statement under the Securities Act to
permit the public resale of the Registrable Securities from time to time, including as permitted by Rule 415 under the Securities Act (or any similar provision then in force), with respect to all of the Registrable Securities (the
“Shelf Registration Statement”) and (ii) cause such Shelf Registration Statement to become effective as soon as reasonably practicable thereafter but in no event later than 60 days after the Closing (the
“Effectiveness Deadline”). The Shelf Registration Statement filed pursuant to this Section 1.01(a) shall be on Form S-3 of the SEC if Parent is eligible to use Form S-3 or Form S-1 of the SEC if
Parent is not eligible to use Form S-3. Subject to Section 1.01(b), Parent will cause the Shelf Registration Statement filed pursuant to this Section 1.01(a) to be continuously effective under the Securities Act from and
after the date it is first declared or becomes effective until all Registrable Securities covered by the Shelf Registration Statement have been distributed in the manner set forth and as contemplated in the Shelf Registration Statement or there are
no longer any Registrable Securities outstanding (the “Effectiveness Period”). The Shelf Registration Statement when declared effective (including the documents incorporated therein by reference) shall comply as to form with
all applicable requirements of the Securities Act and the Exchange Act and shall not contain 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 not
misleading. As soon as practicable following the beginning of the Effectiveness Period, but in any event within three Business Days of such date, Parent will notify the Selling Holders of the effectiveness of such Shelf Registration Statement. 







 (b) Delay Rights. Notwithstanding anything to the contrary contained
herein, Parent may, upon written notice to any Selling Holder whose Registrable Securities are included in the Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Shelf Registration
Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Shelf Registration Statement but such Selling Holder may settle any contracted sales of Registrable Securities) if Parent
(i) is pursuing an acquisition, merger, reorganization, disposition or other similar transaction that Parent reasonably believes would be required by applicable law to be disclosed in the Shelf Registration Statement and the Parent Board
determines in good faith that its ability to pursue or consummate such a transaction would be materially and adversely affected by any required disclosure of such transaction in the Shelf Registration Statement or (ii) has experienced some
other material non-public event the disclosure of which at such time, in the good faith judgment of the Parent Board would materially and adversely affect Parent; provided, however, in no event shall such Selling Holders be
suspended under clauses (i) or (ii) of this Section 1.01(b) from selling Registrable Securities pursuant to the Shelf Registration Statement for a period that exceeds 30 consecutive days or 45 days in the
aggregate. Upon disclosure of such information or the termination of the condition described above, Parent shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Shelf Registration Statement, and shall
promptly terminate any suspension of sales it has put into effect and shall take such other actions to permit registered sales of Registrable Securities as contemplated in this Agreement. 

Section 1.02 Registration Procedures. 

(a) In connection with its obligations under this Article I, Parent will, as expeditiously as possible: 

(i) prepare and file with the SEC such amendments and supplements to the Shelf Registration Statement and the prospectus used
in connection therewith as may be necessary to cause the Shelf Registration Statement to be effective and to keep the Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by the Shelf Registration Statement; 
 (ii) furnish
to each Selling Holder and each Selling Holder’s representatives and counsel designated in writing by such Selling Holder to Parent (A) as far in advance as reasonably practicable before filing the Shelf Registration Statement or any
amendment or supplement thereto a copy of a reasonably complete draft of such Shelf Registration Statement or any amendment or supplement thereto, and provide each such Selling Holder the opportunity to object to any information pertaining to such
Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Shelf Registration Statement or any amendment or
supplement thereto, and (B) a copy of the filed Shelf Registration Statement or any amendment or supplement thereto; 

(iii) promptly notify each Selling Holder, at any time when (A) a prospectus relating thereto is required to be delivered
under the Securities Act, of the filing of the Shelf Registration Statement or any amendment or supplement thereto, and, when the same has become effective, (B) the receipt of any written comments from the SEC with respect to any filings
referred to in clause (A) and any written request by the SEC for amendments or supplements to a Shelf Registration Statement, or (C) copies of any and 

  
 2 








 
all transmittal letters or other correspondence filed via EDGAR with the SEC or any other Governmental Authority relating to a Shelf Registration Statement (it being understood that each Selling
Holder receiving any materials from Parent contemplated herein shall (and shall cause its representatives and counsel to) keep such materials confidential); 

(iv) immediately notify each Selling Holder, each Selling Holder’s representatives and counsel, and each underwriter of
Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (A) the happening of any event as a result of which the prospectus or prospectus supplement contained in the Shelf
Registration Statement or any other registration statement contemplated by this Agreement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the
statements therein not misleading, in the light of the circumstances then existing; (B) the issuance or threat of issuance by the SEC of any stop order suspending the effectiveness of the Shelf Registration Statement or any other registration
statement contemplated by this Agreement, or the initiation of any Proceedings for that purpose; or (C) the receipt by Parent of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under
the applicable securities or “Blue Sky” laws of any jurisdiction. Following the provision of such notice, Parent agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate
action so that the prospectus or prospectus supplement does 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 not misleading, in the light of
the circumstances then existing, and to take such other action as is necessary to remove a stop order, suspension, threat thereof or Proceedings related thereto; 

(b) Each Selling Holder, upon receipt of notice from Parent of the happening of any event of the kind described in
Section 1.02(a)(iv), shall forthwith discontinue disposition of the Registrable Securities until it is advised in writing by Parent that the use of the prospectus may be resumed. Parent shall extend the period of time during which Parent
is required to maintain the Shelf Registration Statement effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of notice from Parent pursuant to Section 1.02(a)(iv) to and
including the date the Selling Holder is advised in writing by Parent that the use of the prospectus may be resumed. 
 Section 1.03
Registrable Securities. Any Registrable Security will cease to be a Registrable Security when (a) a registration statement covering such Registrable Security is effective and such Registrable Security has been sold or disposed of
pursuant to such effective registration statement; (b) such Registrable Security has been disposed of pursuant to any section of Rule 144; or (c) such security becomes eligible for sale pursuant to Rule 144 without volume or
manner-of-sale restrictions and without the requirement for Parent to be in compliance with the current public information requirement under Rule 144(c)(1). 

Section 1.04 Lack of Required Information. Parent shall have no obligation to include in the Shelf Registration Statement any
shares of Subject Common Stock of a Holder who has failed to timely furnish such information which, in the opinion of counsel to Parent, is reasonably required to be furnished or confirmed in order for the registration statement or prospectus
supplement thereto, as applicable, to comply with the Securities Act. 

  
 3 








 Section 1.05 Disclosure of Information. Any Company Stockholder desiring to have its
Registrable Securities included in the Shelf Registration Statement shall provide to Parent all information required to be disclosed therein. Except to the extent such information is disclosed in the Shelf Registration Statement, Parent shall (and
shall cause its agents and representatives to) hold all such information in confidence and not make any disclosure thereof unless (a) the disclosure of such information is necessary to comply with federal or state securities laws, (b) the
disclosure of such information is necessary to avoid or correct an untrue statement of a material fact required to be stated in the Shelf Registration Statement, (c) the release of such information is ordered pursuant to a subpoena or other
final, non-appealable order from a Governmental Authority of competent jurisdiction, or (d) such information has been made generally available to the public other than by disclosure in violation of this Agreement or any other agreement. Parent
agrees that it shall, upon learning that disclosure of any such information (other than that disclosed in the Shelf Registration Statement) is sought in or by a Governmental Authority of competent jurisdiction or through other means, give prompt
written notice to such Company Stockholder and allow such Company Stockholder to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information. 

Section 1.06 Expenses. Parent will pay all expenses incident to Parent’s performance under or compliance with this Agreement
to effect the registration of Registrable Securities on the Shelf Registration Statement, including, without limitation, all registration, filing, securities exchange listing fees, all customary registration, filing, qualification and other fees and
expenses of complying with securities or “Blue Sky” laws, fees of transfer agents and registrars, all word processing, duplicating and printing expenses, and the fees and disbursements of counsel and independent public accountants and
independent reserve engineers for Parent. Notwithstanding the foregoing, “registration expenses” described in this Section 1.06 shall exclude all selling commissions and similar fees and fees of counsel incurred by any Company
Stockholder in connection with the sale of any Registrable Securities. 
 Section 1.07 Opt-Out. At least 10 Business Days before
the initial filing of the Shelf Registration Statement, Parent shall deliver notice to each Company Stockholder (the “Filing Notice”) stating the date (the “Intended Filing Date”) upon which Parent
intends to file the Shelf Registration Statement with the SEC. Notwithstanding whether such Company Stockholder has previously delivered to Parent the information contemplated by Sections 1.04 and 1.05, if a Company Stockholder
delivers a notice to Parent at least three Business Days before the Intended Filing Date stating that such Company Stockholder desires to be excluded from the Shelf Registration Statement, then Parent shall not include the Registrable Securities of
such Company Stockholder, or any information with respect to such Company Stockholder in the Shelf Registration Statement. Parent may for any reason file the Shelf Registration Statement on or after the Intended Filing Date but in no event shall
Parent file the Shelf Registration Statement before the Intended Filing Date. 
 Section 1.08 Indemnification.

 (a) By Parent. In the event of a registration of any Registrable Securities under the Securities Act
pursuant to this Agreement, Parent will indemnify and hold harmless each Selling Holder thereunder, its Affiliates that own Registrable Securities and their respective directors, officers, managers, members, partners, stockholders, Affiliates or any
other Person acting on behalf of such holder of Registrable Securities and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act and its directors, officers, managers, members, partners,
stockholders, Affiliates or any other Person acting on behalf of such holder of Registrable Securities (collectively, the “Selling Holder Indemnified Persons”), against any losses, claims, damages, expenses or liabilities
(including reasonable attorneys’, accountants’ and experts’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder or controlling Person may become subject under the
Securities Act, the 

  
 4 








 
Exchange Act or otherwise, insofar as such Losses (or Proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in the Shelf Registration Statement or any other registration statement contemplated by this Agreement, any prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading,
in connection with the registration statement in respect of any registration of Parent’s securities, and will reimburse each such Selling Holder Indemnified Person for any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such Loss or Proceedings; provided, however, that Parent will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder Indemnified Person in writing specifically for use in the Shelf Registration Statement or such other registration statement or any
prospectus (including, if applicable, any preliminary or free writing prospectus) contained therein or any amendment or supplement thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of
such Selling Holder or any such director, officer or controlling Person, and shall survive the transfer of such securities by such Selling Holder. 

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless
Parent, its directors and officers, and each Person, if any, who controls Parent within the meaning of the Securities Act or of the Exchange Act against any Losses to the same extent as the foregoing indemnity from Parent to the Selling Holders, but
only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Shelf Registration Statement or any prospectus (including, if applicable, any preliminary or
free writing prospectus) contained therein or any amendment or supplement thereof relating to the Registrable Securities; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar
amount of the proceeds received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of
Parent or any such director, officer or controlling Person, and shall survive the transfer of such securities by such Selling Holder. 

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action,
such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but such indemnified party’s failure to so notify the indemnifying party shall
not relieve the indemnifying party from any liability which it may have to any indemnified party other than under this Section 1.07. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume
and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying
party shall not be liable to such indemnified party under this Section 1.07 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of
liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense and employ counsel reasonably acceptable to the indemnified party or (ii) if the defendants in any such
action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified 

  
 5 








 
party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of
the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of one such
separate counsel (firm) and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnified party shall settle any action
brought against it with respect to which it is entitled to indemnification hereunder without the consent of the indemnifying party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional
release from all liability of, the indemnifying party. 
 (d) Contribution. If the indemnification provided for
in this Section 1.07 is held by a Governmental Authority of competent jurisdiction to be unavailable to Parent or any Selling Holder Indemnified Person or is insufficient to hold it harmless in respect of any Losses, then each such
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 as between Parent, on the one hand, and such Selling Holder Indemnified Person,
on the other hand, in such proportion as is appropriate to reflect the relative fault of Parent, on the one hand, and of such Selling Holder Indemnified Person, on the other, in connection with the statements or omissions which resulted in such
Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder Indemnified Person be required to contribute an aggregate amount in excess of the dollar amount of proceeds
received by such Selling Holder Indemnified Person from the sale of Registrable Securities giving rise to such indemnification. The relative fault of Parent, on the one hand, and each Selling Holder Indemnified Person, on the other hand, 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 has been made by, or relates to, information supplied by such party, and
the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were
to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this paragraph. The amount paid by an indemnifying party as a result of the
Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss which is the subject of this
paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation. 

(e) Other Indemnification. The provisions of this Section 1.07 shall be in addition to any other
rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise. 

Section 1.09 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC
that may permit the sale of the Registrable Securities to the public without registration, Parent agrees to use its reasonable best efforts to: 

(a) make and keep public information regarding Parent available, as those terms are understood and defined in Rule 144, at
all times from and after the Closing Date; 

  
 6 








 (b) file with the SEC in a timely manner all reports and other documents required
of Parent under the Securities Act and the Exchange Act at all times from and after the Closing Date; and 
 (c) take such
further action as any Holder may reasonably request, all to the extent required from time to time to enable the Holders to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by
Rule 144. 
 Section 1.10 Regulation M. Parent will not take any direct or indirect action prohibited by Regulation M under
the Exchange Act. 
 Section 1.11 Cooperation. Parent shall cooperate with the holders of the Registrable Securities to
facilitate the timely preparation and delivery of certificates representing the Registrable Securities to be sold pursuant to such Registration Statement or Rule 144 free of any restrictive legends and representing such number of shares of Common
Stock as the holders of the Registrable Securities may reasonably request in connection with any sales of Registrable Securities pursuant to such Registration Statement or Rule 144; provided, that Parent may satisfy its obligations hereunder
without issuing physical stock certificates. 
 Section 1.12 No Transfer or Assignment. Except with respect to a transferee
pursuant to a transfer permitted under Section 1.14(c), the rights to cause Parent to include Registrable Securities in a Shelf Registration Statement may not be transferred or assigned by any Company Stockholder. 

Section 1.13 Requested Information. Any Holder or Holders of Registrable Securities included in any registration statement shall
promptly furnish to Parent such information regarding such Holder or Holders and the distribution or transfer proposed by such Holder or Holders as Parent may reasonably request and as shall be required in connection with any registration,
qualification or compliance referred to herein. 
 Section 1.14 Graduated Lock-up. 

(a) 100% Lock-up Period (0-60 Days). Subject to Section 1.14(c), notwithstanding the filing and
effectiveness of the Shelf Registration Statement, each Holder hereby agrees that it will not (and will cause its Affiliates not to), without the prior written consent of Parent, during the period commencing on the Closing Date and ending
immediately before the commencement of trading on the 61st calendar day immediately following the Closing Date (or, if such calendar day is not a trading day, then the immediately succeeding trading day) (i) lend; offer; pledge; sell; contract
to sell; sell any option or contract to purchase; purchase any option or contract to sell; grant any option, right, or warrant to purchase; or otherwise transfer or dispose of, directly or indirectly, any shares of Subject Common Stock or any
securities convertible into or exercisable or exchangeable (directly or indirectly) for Subject Common Stock (whether such shares or any such securities are then owned by the Holder or are thereafter acquired) or (ii) enter into any swap or
other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (i) or (ii) above is to be settled by
delivery of Subject Common Stock or other securities, in cash, or otherwise. 
 (b) 50% Lock-up Period (61-120
Days). Subject to Section 1.14(c), each Holder hereby agrees that it will not (and will cause its Affiliates not to), without the prior written consent of Parent, during the period commencing at the commencement of trading on the
61st calendar day immediately following the Closing Date (or, if such calendar day is not a trading 

  
 7 








 
day, then the immediately succeeding trading day) and ending immediately before the commencement of trading on the 121st calendar day immediately following the Closing Date (or, if such calendar
day is not a trading day, then the immediately succeeding trading day), (i) lend; offer; pledge; sell; contract to sell; sell any option or contract to purchase; purchase any option or contract to sell; grant any option, right, or warrant to
purchase; or otherwise transfer or dispose of, directly or indirectly, more than 50% of the shares of Subject Common Stock received by such Holder in the Merger or (ii) enter into any swap or other arrangement that transfers to another, in
whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Subject Common Stock or other securities,
in cash, or otherwise. 
 (c) Nothing in this Section 1.14 shall prohibit or limit the ability of any Holder to
effect any transfer of shares of Subject Common Stock as a bona fide gift or gifts or any other similar transfer that does not involve a sale or other disposition for value so long as the transferee agrees in writing to be bound by all of the terms
of this Agreement. 
 Section 1.15 Investment Intent. Each Company Stockholder represents to Parent that it has acquired its
Merger Consideration for its own account and not with the intent to make a distribution within the meaning of the Securities Act or a distribution thereof in violation of any other applicable securities laws. Each Company Stockholder will hold its
Merger Consideration for its own account for investment and not with a view to, or for sale or other disposition in connection with, any distribution of all or any part thereof within the meaning of the Securities Act, except in compliance with
applicable federal and state securities laws.

separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

reference shall be to an Article of, a Section of, or an Exhibit or Schedule to, this Agreement unless otherwise indicated. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” 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. All terms defined in this
Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the
plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such
agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and

Delaware. 
 Section 2.09 WAIVER OF JURY TRIAL. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW THAT CANNOT BE WAIVED, EACH PARTY
HEREBY IRREVOCABLY WAIVES AND COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE) ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY ISSUE, CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING IN WHOLE OR IN PART
UNDER, RELATED TO, BASED ON, OR IN CONNECTION WITH, THIS AGREEMENT OR THE SUBJECT MATTER HEREOF, WHETHER NOW EXISTING OR HEREAFTER ARISING 

  
 10 








 
AND WHETHER SOUNDING IN TORT OR CONTRACT OR OTHERWISE. ANY PARTY MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 2.09 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH
SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY. 
 Section 2.10 Severability of Provisions. Any provision of this
Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting or impairing
the validity or enforceability of such provision in any other jurisdiction. 
 Section 2.11 Entire Agreement. This Agreement is
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, warranties or undertakings, other than those set forth or referred to herein with respect to the rights granted by Parent set forth herein. This Agreement and the Merger Agreement supersede all prior agreements and
