 This
SUPPORT AGREEMENT (this “Agreement”) is made as of November 21, 2022, by and between GRAYBUG VISION, INC., a Delaware corporation (“Parent”),
and the Person set forth on Schedule A hereto (the “Stockholder”). 

WHEREAS, as of the date hereof, the Stockholder is the holder of the number of shares, $0.001 par value per share (“Company
Shares”), of CALCIMEDICA, INC., INC., a Delaware corporation (“Company”), set forth opposite the Stockholder’s name
on Schedule A (all Company Shares owned by the Stockholder, or hereafter issued to or otherwise acquired, whether beneficially or of record, prior to the termination of this Agreement, as well as shares set forth
on Schedule A, being referred to herein as the “Subject Shares”); 
 WHEREAS,
concurrently herewith, the Company, Parent and CAMARO MERGER SUB, INC., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”), have
entered into an Agreement and Plan of Merger and Reorganization, dated as of the date hereof (the “Merger Agreement”), which provides, among other things, for the merger of Merger Sub with and into the Company, with the
Company continuing as the surviving company (the “Merger”), upon the terms and subject to the conditions set forth in the Merger Agreement (capitalized terms used but not otherwise defined herein shall have the respective
meanings ascribed to such terms in the Merger Agreement); and 
 WHEREAS, as a condition to its willingness to enter into the Merger
Agreement, Parent has required that the Stockholder, and as an inducement and in consideration therefor, the Stockholder (in the Stockholder’s capacity as a holder of the Subject Shares) has agreed to, enter into this Agreement. 

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth
below and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, do hereby agree as follows: 

ARTICLE I 
 VOTING
AGREEMENT 
 The Stockholder hereby covenants and agrees that: 

1.1 Voting of Subject Shares. From and after the date hereof, at every meeting of the holders of Company Shares (the
“Company Stockholders”), however called, and at every adjournment or postponement thereof (or pursuant to a written consent if the Company Stockholders act by written consent in lieu of a meeting), the Stockholder shall, or
shall cause the holder of record on any applicable record date to, be present (in person or by proxy) and to vote the Subject Shares (a) in favor of adopting the Merger Agreement and approving the Merger, the other Contemplated Transactions,
the Company Stockholder Matters, and the other actions contemplated by the Merger Agreement, (b) against approval of any proposal made in opposition to, or in competition with, the Merger Agreement or the consummation of the Merger, and
(c) against any Acquisition Proposal with respect to the Company. The Stockholder (or in the event of a Transfer of Subject Shares permitted under clauses (A) through (K) of Section 1.2 below, the transferee of
such Transferred Subject Shares) shall retain at all times the right to vote the Subject Shares in the Stockholder’s sole discretion and without any other limitation on those matters other than those set forth in this
Section 1.1 that are at any time or from time to time presented for consideration to the Company Stockholders. 

 1.2 No Inconsistent Arrangements. Except as provided hereunder or under
the Merger Agreement, prior to the Effective Time, the Stockholder shall not, directly or indirectly, (a) create any Encumbrance other than restrictions imposed by Law or pursuant to this Agreement on any Subject Shares; (b) transfer,
sell, assign, gift or otherwise dispose of (collectively, “Transfer”), or enter into any contract with respect to any Transfer of, the Subject Shares or any interest therein; (c) grant or permit the grant of
any proxy, power of attorney or other authorization in or with respect to the Subject Shares; (d) deposit or permit the deposit of the Subject Shares into a voting trust or enter into a voting agreement or arrangement with respect to the
Subject Shares; or (e) take any action that, to the knowledge of the Stockholder, would have the effect of preventing the Stockholder from performing the Stockholder’s obligations hereunder. Any action taken in violation of the foregoing
sentence shall be null and void ab initio. Notwithstanding the foregoing, the Stockholder may (A) Transfer Subject Shares as a bona fide charitable contribution, gift or donation; (B) Transfer the
Subject Shares to any trust for the direct or indirect benefit of the Stockholder or the immediate family of the Stockholder; (C) Transfer the Subject Shares by will, other testamentary document or intestate succession to the legal
representative, heir, beneficiary or a member of the immediate family of the Stockholder, (D) Transfer the Subject Shares to stockholders, direct or indirect affiliates (within the meaning set forth in Rule 405 under the Securities Act),
current or former partners (general or limited), members or managers of the Stockholder, as applicable, or to the estates of any such stockholders, affiliates, partners, members or managers, or to another corporation, partnership, limited liability
company or other business entity that controls, is controlled by or is under common control with the Stockholder; (E) make Transfers that occur by operation of law pursuant to a qualified domestic relations order or in connection with a divorce
settlement; (F) make Transfers not involving a change in beneficial ownership; (G) if the Stockholder is a trust, Transfer the Subject Shares to any beneficiary of the Stockholder or the estate of any such beneficiary; (H) exercise an
option or warrant to purchase Company Shares or settle a restricted stock unit or other equity award (including a net or cashless exercise of such option or warrant); (I) Transfer Company Shares to Company to cover tax withholding obligations of the
Stockholder in connection with the vesting, settlement or exercise of any options, warrants, restricted stock units or other equity awards, as applicable, provided that the underlying Company Shares shall continue to be subject
to the restrictions on transfer set forth in this Agreement; and (J) Transfer Company Shares to the Company pursuant to arrangements under which the Company has the option to repurchase such Company
Shares; provided that, with respect to clauses (A) through (G) above, the transferee agrees in writing to be bound by the terms and conditions of this Agreement and either the Stockholder or the transferee provides
Parent with a copy of such agreement promptly upon consummation of any such Transfer; provided, further that no filing under the Exchange Act or other public announcement shall be required or shall be made
voluntarily in connection with such Transfer (other than filings made in respect of involuntary Transfers); provided that reasonable notice shall be provided to Parent prior to any such filing and that that the underlying
Company Shares shall continue to be subject to the restrictions on Transfer set forth in this Agreement. For purposes of this Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than
first cousin. 
 1.3 Documentation and Information. The Stockholder shall permit and hereby authorizes the Company and
Parent to publish and disclose in all documents and schedules filed with the SEC, and any press release or other disclosure document that the Company or Parent reasonably determines to be necessary in connection with the Merger and any of the
Contemplated Transactions, the Stockholder’s identity and ownership of the Subject Shares and the nature of the Stockholder’s commitments and obligations under this Agreement. The Company is an intended third-party beneficiary of
this Section 1.3. 
 1.4 Irrevocable Proxy. The Stockholder hereby revokes (or
agrees to cause to be revoked) any proxies that the Stockholder has heretofore granted with respect to the Subject Shares. In the event and to the extent that the Stockholder fails to vote the Subject Shares in accordance with Section 1.1, the
Stockholder shall be deemed to have irrevocably granted to, and appointed, Parent as attorney-in-fact and proxy for and on behalf of the Stockholder, for and in the
name, place and stead of the Stockholder, to: (a) 

  
 2 

 
attend any and all meetings of Company Stockholders, with respect to any of the matters specified in Section 1.1, (b) vote, express consent or dissent or issue instructions to the record
holder to vote the Subject Shares in accordance with the provisions of Section 1.1 at any and all meetings of Company Stockholders or in connection with any action sought to be taken by written consent of Company Stockholders without a meeting
and (c) grant or withhold, or issue instructions to the record holder to grant or withhold, consistent with the provisions of Section 1.1, all written consents with respect to the Subject Shares at any and all meetings of Company
Stockholders or in connection with any action sought to be taken by written consent of Company Stockholders without a meeting. Parent agrees not to exercise the proxy granted herein for any purpose other than the purposes described in this
Agreement. The foregoing proxy shall be deemed to be a proxy coupled with an interest, is irrevocable (and as such shall survive and not be affected by the death, incapacity, mental illness or insanity of the Stockholder, as applicable) until the
termination of this Agreement and shall not be terminated by operation of law or upon the occurrence of any other event other than the termination of this Agreement pursuant to Section 4.2. The Stockholder authorizes such attorney and proxy to
substitute any other Person to act hereunder, to revoke any substitution and to file this proxy and any substitution or revocation with the Secretary of Company. The Stockholder hereby affirms that the proxy set forth in this Section 1.4 is
given in connection with and granted in consideration of and as an inducement to Parent, Merger Sub and the Company to enter into the Merger Agreement and that such proxy is given to secure the obligations of the Stockholder under Section 1.1.
The proxy set forth in this Section 1.4 is executed and intended to be irrevocable, subject, however, to its automatic termination upon the termination of this Agreement pursuant to Section 4.2. With respect to any Subject Shares that are
owned beneficially by the Stockholder but are not held of record by the Stockholder (other than shares beneficially owned by the Stockholder that are held in the name of a bank, broker or nominee), the Stockholder shall take all action necessary to
cause the record holder of such Subject Shares to grant the irrevocable proxy and take all other actions provided for in this Section 1.4 with respect to such Subject Shares. 

1.5 No Ownership Interest. Nothing contained in this Agreement will be deemed to vest in Parent any direct or indirect
ownership or incidents of ownership of or with respect to the Subject Shares. All rights, ownership and economic benefits of and relating to the Subject Shares will remain and belong to the Stockholder, and Parent will have no authority to manage,
direct, superintend, restrict, regulate, govern or administer any of the policies or operations of the Company or exercise any power or authority to direct the Stockholder in the voting of any of the Subject Shares, except as otherwise expressly
provided herein with respect to the Subject Shares and except as otherwise expressly provided in the Merger Agreement. 
 1.6
No Exercise of Appraisal Rights; Waivers. In connection with the Contemplated Transactions, the Stockholder hereby expressly (a) waives, to the extent permitted under applicable Law, any and all rights under Section 262 of
the Delaware General Corporation Law, a copy of which is attached hereto as Appendix I, and Chapter 13 of the California Corporations Code, as amended, a copy of which is attached hereto as Appendix II, with respect to any Subject Shares and any and
all rights under any other applicable Law granting the Stockholder the right to have any Subject Shares appraised in connection with the Contemplated Transactions or to otherwise dissent from the Contemplated Transactions, (b) agrees that the
Stockholder will not, under any circumstances in connection with the Contemplated Transactions, exercise any dissenters’ or appraisal rights in respect of any Subject Shares, and (c) agrees that the Stockholder will not bring, commence,
institute, maintain, prosecute, participate in or voluntarily aid any action, claim, suit or cause of action, in law or in equity, in any court or before any Governmental Body, which (i) challenges the validity of or seeks to enjoin the
operation of any provision of this Agreement or (ii) alleges that the execution and delivery of this Agreement by the Stockholder, or the approval of the Merger Agreement by the board of directors of the Company (the “Company
Board”), breaches any fiduciary duty of the Company Board or any member thereof; provided that the Stockholder may defend against, contest or settle any such action, claim, suit or cause of action brought
against the Stockholder that relates solely to the Stockholder’s capacity as a director, officer or securityholder of the Company. 

  
 3 

 1.7 No Solicitation of Transactions. The Stockholder hereby agrees that
the Stockholder shall not, directly or indirectly: (a) solicit, initiate or knowingly encourage, induce or facilitate the communication, making, submission or announcement of any Acquisition Proposal or Acquisition Inquiry or take any
action that could reasonably be expected to lead to an Acquisition Proposal or Acquisition Inquiry; (b) furnish any non-public information regarding the Company to any Person in connection with
or in response to an Acquisition Proposal or Acquisition Inquiry; (c) engage in discussions (other than to inform any Person of the existence of the provisions in this Section 1.7) or negotiations with any Person with
respect to any Acquisition Proposal or Acquisition Inquiry; (d) approve, endorse or recommend any Acquisition Proposal; (e) execute or enter into any letter of intent or any Contract contemplating or otherwise relating to any Acquisition
Transaction; or (f) publicly propose to do any of the foregoing. The Stockholder hereby represents and warrants that the Stockholder has read Section 4.5 (Company Non-Solicitation) of the Merger
Agreement and agrees not to engage in any actions prohibited thereby. 
 ARTICLE II 

REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDER 

The Stockholder represents and warrants to Parent that: 

2.1 Organization; Authorization; Binding Agreement. The Stockholder, if not a natural person, is duly incorporated or
organized, as applicable, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization. The Stockholder has full legal capacity and power, right and authority to execute and deliver this Agreement and to
perform the Stockholder’s obligations hereunder and to consummate the transactions contemplated hereby. This Agreement has been duly and validly executed and delivered by the Stockholder, and constitutes a legal, valid and binding obligation of
the Stockholder enforceable against the Stockholder in accordance with its terms, subject to the Enforceability Exceptions. 
 2.2
Ownership of Subject Shares; Total Shares. The Stockholder is the record or beneficial owner of the Subject Shares and has good and marketable title to the Subject Shares free and clear of any Encumbrances (including any restriction on
the right to vote or otherwise transfer the Subject Shares), except (a) as provided hereunder or in any lock-up agreement entered into by the Stockholder in connection with the transactions
contemplated by the Merger Agreement, (b) pursuant to any applicable restrictions on transfer under the Securities Act, (c) subject to any risk of forfeiture or repurchase rights of the Company with respect to any Company Shares granted to
the Stockholder under any Company Benefit Plan or Company Plan, (d) as provided in the Investor Agreements, (e) as provided in the Company Plan or stock option agreement evidencing Company Options and (f) as provided in the
Organizational Documents of the Company. The Subject Shares listed on Schedule A opposite the Stockholder’s name constitute all of the Company Shares owned by the Stockholder as of the date hereof. Except
pursuant to the Company’s Organizational Documents and the right of the Company to purchase or acquire any Company Shares pursuant to a Company Benefit Plan or Company Plan, including any option agreement evidencing Company Options, no Person
has any contractual or other right or obligation to purchase or otherwise acquire any of the Subject Shares. For purposes of this Agreement “Beneficial Ownership” shall be interpreted as defined
in Rule 13d-3 under the Exchange Act; provided that for purposes of determining Beneficial Ownership, a Person shall be deemed to be the Beneficial Owner of any securities
that may be acquired by such Person pursuant to any Contract or upon the exercise of conversion rights, exchange rights, warrants or options, or otherwise (irrespective of whether the right to acquire such securities is exercisable immediately or
only after the passage of time, including the passage of time in excess of 60 days, the satisfaction of any conditions, the occurrence of any event or any combination of the foregoing). 

  
 4 

 2.3 Voting Power. The Stockholder has full voting power with respect to
the Subject Shares, and full power of disposition, full power to issue instructions with respect to the matters set forth herein and full power to agree to all of the matters set forth herein, in each case, with respect to all of the Subject Shares.
None of the Subject Shares are subject to any proxy, voting trust or other agreement or arrangement with respect to the voting of the Subject Shares, except as provided hereunder or in the Investor Agreements. 

2.4 Reliance. The Stockholder has had the opportunity to review the Merger Agreement, including the provisions relating
to the payment and allocation of the consideration to be paid to the equityholders of the Company, and this Agreement with counsel of the Stockholder’s own choosing. The Stockholder has had an opportunity to review with its own tax advisors the
tax consequences of the Merger and the transactions contemplated by the Merger Agreement. The Stockholder understands that it must rely solely on its advisors and not on any statements or representations made by Parent, the Company or any of their
respective agents or representatives. The Stockholder understands that such Stockholder (and not Parent, the Company or the Surviving Corporation) shall be responsible for such Stockholder’s tax liability that may arise as a result of the
Merger or the transactions contemplated by the Merger Agreement. The Stockholder understands and acknowledges that the Company, Parent and Merger Sub are entering into the Merger Agreement in reliance upon the Stockholder’s execution, delivery
and performance of this Agreement. 
 2.5 Absence of Litigation. With respect to the Stockholder, as of the date
hereof, there is no action, suit, investigation or proceeding pending against, or, to the knowledge of the Stockholder, threatened in writing against, the Stockholder or any of the Stockholder’s properties or assets (including the Subject
Shares) that could reasonably be expected to prevent, delay or impair the ability of the Stockholder to perform the Stockholder’s obligations hereunder or to consummate the transactions contemplated hereby. 

2.6 Non-Contravention. The execution and delivery of this Agreement by the
Stockholder and the performance of the transactions contemplated by this Agreement by the Stockholder do not and will not violate, conflict with, or result in a breach of: (a) the organizational documents of such Stockholder, (b) any
applicable Law or any injunction, judgment, order, decree, ruling, charge, or other restriction of any Governmental Body to which the Stockholder is subject, or (c) any Contract to which the Stockholder is a party or is bound or to which the
Subject Shares are subject, such that it could reasonably be expected to prevent, delay or impair the ability of the Stockholder to perform the Stockholder’s obligations hereunder or to consummate the transactions contemplated hereby.

 4.2 Termination. This Agreement shall terminate automatically, without any notice or other action by any Person,
upon the earliest of (a) the termination of the Merger Agreement in accordance with its terms, (b) the date upon which the Company Board makes a Company Board Adverse Recommendation Change, and (c) the Effective Time. Upon termination

this Agreement. 
 4.3 Confidentiality. Except to the extent required by applicable Law, the Stockholder shall hold any non-public information regarding this Agreement, the Merger Agreement and the Merger in strict confidence and shall not divulge any such information to any third person until Parent has
publicly disclosed its entry into the Merger Agreement and this Agreement; provided, however, that the Stockholder may disclose such information (a) to its attorneys, accountants, consultants,
trustees, beneficiaries and other representatives and (b) to any Affiliate, partner, member, stockholder, parent or subsidiary of Stockholder, provided in each case that the Stockholder informs the Person
receiving the information that such information is confidential and such Person is subject to confidentiality obligations at least as restrictive as those contained herein. Neither the Stockholder nor any of its Affiliates (other than the Company,
whose actions shall be governed by the Merger Agreement) shall issue or cause the publication of any press release or other public announcement with respect to this Agreement, the Merger, the Merger Agreement or the other transactions contemplated
hereby or thereby without the prior written consent of the Company and Parent, except as may be required by applicable Law in which circumstance such announcing party shall make reasonable efforts to consult with the Company and Parent to the extent
practicable. The Company is an intended third-party beneficiary of this Section 4.3. 
 4.4
Amendments and Waivers. Any provision of this Agreement may be amended or waived if such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement, or in the case of a waiver, by the
party against whom the waiver is to be effective. No failure or delay by either party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right, power or privilege. 
 4.5 Binding Effect; Benefit;
Assignment. The provisions of this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. Except as set forth
in Section 1.3 and Section 4.3, no provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person other than
the parties hereto and their respective successors and assigns. Neither party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of the other party hereto, except that Parent may
transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to one or more of its Affiliates at any time; provided that such transfer or assignment shall not relieve Parent of
any of its obligations hereunder. 
 4.6 Governing Law; Jurisdiction. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws. In any action or proceeding between any of the parties hereto arising out of or
relating to this Agreement, each party hereto: (a) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of 

  
 6 

 
Delaware or, to the extent such court does not have subject matter jurisdiction, the United States District Court for the District of Delaware or, to the extent that neither of the foregoing
courts has jurisdiction, the Superior Court of the State of Delaware (the “Delaware Courts”); (b) agrees that all claims in respect of such action or proceeding shall be heard and determined exclusively in accordance with
clause (a) of this Section 4.6; (c) waives any objection to laying venue in any such action or proceeding in such courts; (d) waives any objection that such courts are an inconvenient forum or do not have
jurisdiction over any party hereto; (e) agrees that service of process upon such party in any such action or proceeding shall be effective if notice is given in accordance with Section 4.1 of this Agreement; and
(f) irrevocably and unconditionally waives the right to trial by jury. 
 4.7 Counterparts. This Agreement may be
executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by all parties by facsimile or
electronic transmission in .PDF format shall be sufficient to bind the parties to the terms and conditions of this Agreement. 
 4.8
Entire Agreement. This Agreement constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, among or between any of the parties with respect to the subject matter hereof and thereof.

 4.9 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any
jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final
judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the parties hereto agree that the court making such determination will have the power to limit such term or provision,
to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement
shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and
enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision. 

4.10 Specific Performance. Any and all remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would
occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to
prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any Delaware Court, this being in addition to any other remedy to which they are entitled at law or in equity, and each of the parties hereto waives
any bond, surety or other security that might be required of any other party with respect thereto. 
 4.11
Construction. 
 (a) For purposes of this Agreement, whenever the context requires: the singular number shall include the
plural, and vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include masculine and feminine genders. 

  
 7 

 (b) The parties hereto agree that any rule of construction to the effect that ambiguities
are to be resolved against the drafting party shall not be applied in the construction or interpretation of this Agreement. 
 (c) As used
in this Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.” 

(d) Except as otherwise indicated, all references in this Agreement to “Sections,” “Articles,” and “Schedules”
are intended to refer to Sections or Articles of this Agreement and Schedules to this Agreement, respectively. 
 (e) The bold-faced
headings contained in this Agreement are for convenience of reference only, shall not be deemed to be a part of this Agreement and shall not be referred to in connection with the construction or interpretation of this Agreement. 

4.12 Further Assurances. Each of the parties hereto will execute and deliver, or cause to be executed and delivered, all
further documents and instruments and use their respective reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary under applicable Law to perform their respective obligations as
expressly set forth under this Agreement. 
 4.13 Capacity as Stockholder. The Stockholder signs this Agreement solely
in the Stockholder’s capacity as a holder of Company Shares, and not in the Stockholder’s capacity as a director, officer or employee of Company or in the Stockholder’s capacity as a trustee or fiduciary of any employee benefit plan
or trust. Notwithstanding anything herein to the contrary, nothing herein shall in any way restrict a director or officer of Company in the exercise of his or her fiduciary duties as a director or officer of Company or in his or her capacity as a
trustee or fiduciary of any employee benefit plan or trust or prevent or be construed to create any obligation on the part of any director or officer of Company or any trustee or fiduciary of any employee benefit plan or trust from taking any action
in his or her capacity as such director, officer, trustee or fiduciary. 
 4.14 No Agreement Until Executed.
Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement shall not constitute or be deemed to evidence a contract, agreement, arrangement or understanding between the parties hereto unless and
until (a) the Company Board has approved, for purposes of any applicable anti-takeover laws and regulations, and any applicable provision of the Company’s Organizational Documents, the Merger, (b) the Merger Agreement is executed by
all parties thereto, and (c) this Agreement is executed by all parties hereto.

§ 262. Appraisal rights [For application of this section, see § 17; 82 Del. Laws, c. 45, § 23; 82 Del. Laws, c. 256, § 24; and 83 Del.
Laws, c. 377, § 22]. 
 (a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making
of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger, consolidation, or conversion, who has otherwise complied with subsection
(d) of this section and who has neither voted in favor of the merger, consolidation or conversion nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value
of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a corporation; the words
“stock” and “share” mean and include what is ordinarily meant by those words; the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in 1 or more shares, or
fractions thereof, solely of stock of a corporation, which stock is deposited with the depository; the words “beneficial owner” mean a person who is the beneficial owner of shares of stock held either in voting trust or by a nominee on
behalf of such person; and the word “person” means any individual, corporation, partnership, unincorporated association or other entity. 

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent or converting corporation in a merger,
consolidation or conversion to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 255, § 256, § 257, § 258, § 263, § 264 or § 266 of
this title (other than, in each case and solely with respect to a domesticated corporation, a merger, consolidation or conversion authorized pursuant to and in accordance with the provisions of § 388 of this title): 

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which
stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders, or at the record date fixed to determine the stockholders entitled to consent
pursuant to § 228 of this title, to act upon the agreement of merger or consolidation or the resolution providing for conversion (or, in the case of a merger pursuant to § 251(h) of this title, as of immediately prior to the execution of
the agreement of merger), were either: (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the
constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title. 

(2) Notwithstanding paragraph (b)(1) of this section, appraisal rights under this section shall be available for the shares of any class or
series of stock of a constituent or converting corporation if the holders thereof are required by the terms of an agreement of merger or consolidation, or by the terms of a resolution providing for conversion, pursuant to § 251,
§ 252, § 254, § 255, § 256, § 257, § 258, § 263, § 264 or § 266 of this title to accept for such stock anything except: 

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or of the converted entity if such entity is a
corporation as a result of the conversion, or depository receipts in respect thereof; 
 b. Shares of stock of any other corporation, or
depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger, consolidation or conversion will be either listed on a national securities exchange
or held of record by more than 2,000 holders; 

 c. Cash in lieu of fractional shares or fractional depository receipts described in the
foregoing paragraphs (b)(2)a. and b. of this section; or 
 d. Any combination of the shares of stock, depository receipts and cash in lieu
of fractional shares or fractional depository receipts described in the foregoing paragraphs (b)(2)a., b. and c. of this section. 
 (3) In
the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 or § 267 of this title is not owned by the parent immediately prior to the merger, appraisal rights shall be available for the shares of
the subsidiary Delaware corporation. 
 (4) [Repealed.] 

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares
of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation, the sale of all or substantially all of the assets of the
corporation or a conversion effected pursuant to § 266 of this title. If the certificate of incorporation contains such a provision, the provisions of this section, including those set forth in subsections (d), (e), and (g) of this
section, shall apply as nearly as is practicable. 
 (d) Appraisal rights shall be perfected as follows: 

(1) If a proposed merger, consolidation or conversion for which appraisal rights are provided under this section is to be submitted for
approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting (or such members who received notice in accordance
with § 255(c) of this title) with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) of this section that appraisal rights are available for any or all of the shares of the constituent corporations
or the converting corporation, and shall include in such notice either a copy of this section (and, if 1 of the constituent corporations or the converting corporation is a nonstock corporation, a copy of § 114 of this title) or information
directing the stockholders to a publicly available electronic resource at which this section (and, § 114 of this title, if applicable) may be accessed without subscription or cost. Each stockholder electing to demand the appraisal of such
stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger, consolidation or conversion, a written demand for appraisal of such stockholder’s shares; provided that a demand may be delivered to the
corporation by electronic transmission if directed to an information processing system (if any) expressly designated for that purpose in such notice. Such demand will be sufficient if it reasonably informs the corporation of the identity of the
stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger, consolidation or conversion shall not constitute such a demand. A stockholder electing to take such
action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger, consolidation or conversion, the surviving, resulting or converted entity shall notify each stockholder of each constituent or
converting corporation who has complied with this subsection and has not voted in favor of or consented to the merger, consolidation or conversion, and any beneficial owner who has demanded appraisal under paragraph (d)(3) of this section, of the
date that the merger, consolidation or conversion has become effective; or 
 (2) If the merger, consolidation or conversion was approved
pursuant to § 228, § 251(h), § 253, or § 267 of this title, then either a constituent or converting corporation before the effective date of the merger, consolidation or conversion, or the surviving, resulting or converted entity
within 10 days after such effective date, shall notify each stockholder of any class or series of stock of such constituent or converting corporation who is entitled to appraisal rights of the approval of the merger,

  
 2 

 
consolidation or conversion and that appraisal rights are available for any or all shares of such class or series of stock of such constituent or converting corporation, and shall include in such
notice either a copy of this section (and, if 1 of the constituent corporations or the converting corporation is a nonstock corporation, a copy of § 114 of this title) or information directing the stockholders to a publicly available electronic
resource at which this section (and § 114 of this title, if applicable) may be accessed without subscription or cost. Such notice may, and, if given on or after the effective date of the merger, consolidation or conversion, shall, also notify
such stockholders of the effective date of the merger, consolidation or conversion. Any stockholder entitled to appraisal rights may, within 20 days after the date of giving such notice or, in the case of a merger approved pursuant to § 251(h)
of this title, within the later of the consummation of the offer contemplated by § 251(h) of this title and 20 days after the date of giving such notice, demand in writing from the surviving or resulting entity the appraisal of such
holder’s shares; provided that a demand may be delivered to such entity by electronic transmission if directed to an information processing system (if any) expressly designated for that purpose in such notice. Such demand will be sufficient if
it reasonably informs such entity of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger,
consolidation or conversion, either (i) each such constituent corporation or the converting corporation shall send a second notice before the effective date of the merger, consolidation or conversion notifying each of the holders of any class
or series of stock of such constituent or converting corporation that are entitled to appraisal rights of the effective date of the merger, consolidation or conversion or (ii) the surviving, resulting or converted entity shall send such a
second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice or, in the case of a merger approved pursuant to
§ 251(h) of this title, later than the later of the consummation of the offer contemplated by § 251(h) of this title and 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is
entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection and any beneficial owner who has demanded appraisal under paragraph (d)(3) of this section. An affidavit of the secretary or
assistant secretary or of the transfer agent of the corporation or entity that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of
determining the stockholders entitled to receive either notice, each constituent corporation or the converting corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that
if the notice is given on or after the effective date of the merger, consolidation or conversion, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be
the close of business on the day next preceding the day on which the notice is given. 
 (3) Notwithstanding subsection (a) of this
section (but subject to this paragraph (d)(3)), a beneficial owner may, in such person’s name, demand in writing an appraisal of such beneficial owner’s shares in accordance with either paragraph (d)(1) or (2) of this section, as
applicable; provided that (i) such beneficial owner continuously owns such shares through the effective date of the merger, consolidation or conversion and otherwise satisfies the requirements applicable to a stockholder under the first
sentence of subsection (a) of this section and (ii) the demand made by such beneficial owner reasonably identifies the holder of record of the shares for which the demand is made, is accompanied by documentary evidence of such beneficial
owner’s beneficial ownership of stock and a statement that such documentary evidence is a true and correct copy of what it purports to be, and provides an address at which such beneficial owner consents to receive notices given by the
surviving, resulting or converted entity hereunder and to be set forth on the verified list required by subsection (f) of this section. 

  
 3 

 (e) Within 120 days after the effective date of the merger, consolidation or conversion, the
surviving, resulting or converted entity, or any person who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the
Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger, consolidation or conversion, any person entitled to
appraisal rights who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such person’s demand for appraisal and to accept the terms offered upon the merger, consolidation or
conversion. Within 120 days after the effective date of the merger, consolidation or conversion, any person who has complied with the requirements of subsections (a) and (d) of this section hereof, upon request given in writing (or by
electronic transmission directed to an information processing system (if any) expressly designated for that purpose in the notice of appraisal), shall be entitled to receive from the surviving, resulting or converted entity a statement setting forth
the aggregate number of shares not voted in favor of the merger, consolidation or conversion (or, in the case of a merger approved pursuant to § 251(h) of this title, the aggregate number of shares (other than any excluded stock (as defined in
§ 251(h)(6)d. of this title)) that were the subject of, and were not tendered into, and accepted for purchase or exchange in, the offer referred to in § 251(h)(2) of this title)), and, in either case, with respect to which demands for
appraisal have been received and the aggregate number of stockholders or beneficial owners holding or owning such shares (provided that, where a beneficial owner makes a demand pursuant to paragraph (d)(3) of this section, the record holder of such
shares shall not be considered a separate stockholder holding such shares for purposes of such aggregate number). Such statement shall be given to the person within 10 days after such person’s request for such a statement is received by the
surviving, resulting or converted entity or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. 

(f) Upon the filing of any such petition by any person other than the surviving, resulting or converted entity, service of a copy thereof shall
be made upon such entity, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all persons who have demanded appraisal
for their shares and with whom agreements as to the value of their shares have not been reached by such entity. If the petition shall be filed by the surviving, resulting or converted entity, the petition shall be accompanied by such a duly verified
list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving, resulting or converted entity and to the persons shown on
the list at the addresses therein stated. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving, resulting or converted entity. 

(g) At the hearing on such petition, the Court shall determine the persons who have complied with this section and who have become entitled to
appraisal rights. The Court may require the persons who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency
of the appraisal proceedings; and if any person fails to comply with such direction, the Court may dismiss the proceedings as to such person. If immediately before the merger, consolidation or conversion the shares of the class or series of stock of
the constituent or converting corporation as to which appraisal rights are available were listed on a national securities exchange, the Court shall dismiss the proceedings as to all holders of such shares who are otherwise entitled to appraisal
rights unless (1) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of the class or series eligible for appraisal, (2) the value of the consideration provided in the merger, consolidation or conversion
for such total number of shares exceeds $1 million, or (3) the merger was approved pursuant to § 253 or § 267 of this title. 

  
 4 

 (h) After the Court determines the persons entitled to an appraisal, the appraisal
proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any
element of value arising from the accomplishment or expectation of the merger, consolidation or conversion, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall
take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, and except as provided in this subsection, interest from the effective date of the merger, consolidation or conversion through the
date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger,
consolidation or conversion and the date of payment of the judgment. At any time before the entry of judgment in the proceedings, the surviving, resulting or converted entity may pay to each person entitled to appraisal an amount in cash, in which
case interest shall accrue thereafter as provided herein only upon the sum of (1) the difference, if any, between the amount so paid and the fair value of the shares as determined by the Court, and (2) interest theretofore accrued, unless
paid at that time. Upon application by the surviving, resulting or converted entity or by any person entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final
determination of the persons entitled to an appraisal. Any person whose name appears on the list filed by the surviving, resulting or converted entity pursuant to subsection (f) of this section may participate fully in all proceedings until it
is finally determined that such person is not entitled to appraisal rights under this section. 
 (i) The Court shall direct the payment of
the fair value of the shares, together with interest, if any, by the surviving, resulting or converted entity to the persons entitled thereto. Payment shall be so made to each such person upon such terms and conditions as the Court may order. The
Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving, resulting or converted entity be an entity of this State or of any state. 

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances.
Upon application of a person whose name appears on the list filed by the surviving, resulting or converted entity pursuant to subsection (f) of this section who participated in the proceeding and incurred expenses in connection therewith, the
Court may order all or a portion of such expenses, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal not dismissed
pursuant to subsection (k) of this section or subject to such an award pursuant to a reservation of jurisdiction under subsection (k) of this section. 

(k) From and after the effective date of the merger, consolidation or conversion, no person who has demanded appraisal rights with respect to
some or all of such person’s shares as provided in subsection (d) of this section shall be entitled to vote such shares for any purpose or to receive payment of dividends or other distributions on such shares (except dividends or other
distributions payable to stockholders of record at a date which is prior to the effective date of the merger, consolidation or conversion); provided, however, that if no petition for an appraisal is filed within the time provided in subsection
(e) of this section, or if a person who has made a demand for an appraisal in accordance with this section shall deliver to the surviving, resulting or converted entity a written withdrawal of such person’s demand for an appraisal in
respect of some or all of such person’s shares in accordance with subsection (e) of this section, then the right of such person to an appraisal of the shares subject to the withdrawal shall cease. Notwithstanding the foregoing, no
appraisal proceeding in the Court of Chancery shall be dismissed as to any person without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just, including without limitation, a reservation of
jurisdiction for any application to the Court made under subsection (j) of this section; provided, however that this provision shall not affect the right of any person who has not commenced an appraisal proceeding or joined that proceeding as a
named party to withdraw such person’s demand for appraisal and to accept the terms offered upon the merger, consolidation or conversion within 60 days after the effective date of the merger, consolidation or conversion, as set forth in
subsection (e) of this section. 

  
 5 

 (l) The shares or other equity interests of the surviving, resulting or converted entity to
which the shares of stock subject to appraisal under this section would have otherwise converted but for an appraisal demand made in accordance with this section shall have the status of authorized but not outstanding shares of stock or other equity
interests of the surviving, resulting or converted entity, unless and until the person that has demanded appraisal is no longer entitled to appraisal pursuant to this section.

 Appendix II 

CHAPTER 13. Dissenters’ Rights [1300 - 1313] 

(Chapter 13 added by Stats. 1975, Ch. 682.) 
 1300.

 (a) If the approval of the outstanding shares (Section 152) of a corporation is required for a reorganization under subdivisions (a) and
(b) or subdivision (e) or (f) of Section 1201, each shareholder of the corporation entitled to vote on the transaction and each shareholder of a subsidiary corporation in a short-form merger may, by complying with this chapter,
require the corporation in which the shareholder holds shares to purchase for cash at their fair market value the shares owned by the shareholder which are dissenting shares as defined in subdivision (b). The fair market value shall be determined as
of the day of, and immediately prior to, the first announcement of the terms of the proposed reorganization or short-form merger, excluding any appreciation or depreciation in consequence of the proposed reorganization or short-form merger, as
adjusted for any stock split, reverse stock split, or share dividend that becomes effective thereafter. 
 (b) As used in this chapter, “dissenting
shares” means shares to which all of the following apply: 
 (1) That were not, immediately prior to the reorganization or short-form merger, listed on
any national securities exchange certified by the Commissioner of Business Oversight under subdivision (o) of Section 25100, and the notice of meeting of shareholders to act upon the reorganization summarizes this section and Sections
1301, 1302, 1303, and 1304; provided, however, that this provision does not apply to any shares with respect to which there exists any restriction on transfer imposed by the corporation or by any law or regulation; and provided, further, that this
provision does not apply to any shares where the holder of those shares is required, by the terms of the reorganization or short-form merger, to accept for the shares anything except: (A) shares of any other corporation, which shares, at the
time the reorganization or short-form merger is effective, are listed on any national securities exchange certified by the Commissioner of Business Oversight under subdivision (o) of Section 25100; (B) cash in lieu of fractional shares
described in the foregoing subparagraph (A); or (C) any combination of the shares and cash in lieu of fractional shares described in the foregoing subparagraphs (A) and (B). 

(2) That were outstanding on the date for the determination of shareholders entitled to vote on the reorganization and (A) were not voted in favor of the
reorganization or, (B) if described in paragraph (1), were voted against the reorganization, or were held of record on the effective date of a short-form merger; provided, however, that subparagraph (A) rather than subparagraph (B) of
this paragraph applies in any case where the approval required by Section 1201 is sought by written consent rather than at a meeting. 
 (3) That the
dissenting shareholder has demanded that the corporation purchase at their fair market value, in accordance with Section 1301. 
 (4) That the
dissenting shareholder has submitted for endorsement, in accordance with Section 1302. 
 (c) As used in this chapter, “dissenting
shareholder” means the recordholder of dissenting shares and includes a transferee of record. 
 (Amended by Stats. 2019, Ch. 143, Sec. 24. (SB 251)
Effective January 1, 2020.) 

 1301. 

(a) If, in the case of a reorganization, any shareholders of a corporation have a right under Section 1300, subject to compliance with paragraphs
(3) and (4) of subdivision (b) thereof, to require the corporation to purchase their shares for cash, that corporation shall mail to each of those shareholders a notice of the approval of the reorganization by its outstanding shares
(Section 152) within 10 days after the date of that approval, accompanied by a copy of Sections 1300, 1302, 1303, and 1304 and this section, a statement of the price determined by the corporation to represent the fair market value of the dissenting
shares, and a brief description of the procedure to be followed if the shareholder desires to exercise the shareholder’s right under those sections. The statement of price constitutes an offer by the corporation to purchase at the price stated
any dissenting shares as defined in subdivision (b) of Section 1300, unless they lose their status as dissenting shares under Section 1309. 

(b) Any shareholder who has a right to require the corporation to purchase the shareholder’s shares for cash under Section 1300, subject to
compliance with paragraphs (3) and (4) of subdivision (b) thereof, and who desires the corporation to purchase shares shall make written demand upon the corporation for the purchase of those shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose unless it is received by the corporation or any transfer agent thereof (1) in the case of shares described in subdivision (b) of Section 1300, not later than
the date of the shareholders’ meeting to vote upon the reorganization, or (2) in any other case, within 30 days after the date on which the notice of the approval by the outstanding shares pursuant to subdivision (a) or the notice
pursuant to subdivision (h) of Section 1110 was mailed to the shareholder. 
 (c) The demand shall state the number and class of the shares held
of record by the shareholder which the shareholder demands that the corporation purchase and shall contain a statement of what the shareholder claims to be the fair market value of those shares as determined pursuant to subdivision (a) of
Section 1300. The statement of fair market value constitutes an offer by the shareholder to sell the shares at that price. 
 (Amended by Stats.
2012, Ch. 473, Sec. 2. (AB 1680) Effective January 1, 2013.) 
 1302. 

Within 30 days after the date on which notice of the approval by the outstanding shares or the notice pursuant to subdivision (h) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at its principal office or at the office of any transfer agent thereof, (a) if the shares are certificated securities, the shareholder’s certificates representing
any shares which the shareholder demands that the corporation purchase, to be stamped or endorsed with a statement that the shares are dissenting shares or to be exchanged for certificates of appropriate denomination so stamped or endorsed or
(b) if the shares are uncertificated securities, written notice of the number of shares which the shareholder demands that the corporation purchase. Upon subsequent transfers of the dissenting shares on the books of the corporation, the new
certificates, initial transaction statement, and other written statements issued therefor shall bear a like statement, together with the name of the original dissenting holder of the shares. 

(Amended by Stats. 2012, Ch. 473, Sec. 3. (AB 1680) Effective January 1, 2013.) 

  
 2 

 1303. 

(a) If the corporation and the shareholder agree that the shares are dissenting shares and agree upon the price of the shares, the dissenting shareholder is
entitled to the agreed price with interest thereon at the legal rate on judgments from the date of the agreement. Any agreements fixing the fair market value of any dissenting shares as between the corporation and the holders thereof shall be filed
with the secretary of the corporation. 
 (b) Subject to the provisions of Section 1306, payment of the fair market value of dissenting shares
shall be made within 30 days after the amount thereof has been agreed or within 30 days after any statutory or contractual conditions to the reorganization are satisfied, whichever is later, and in the case of certificated securities,
subject to surrender of the certificates therefor, unless provided otherwise by agreement. 
 (Amended by Stats. 1986, Ch. 766, Sec. 24.) 

1304. 
 (a) If the corporation denies that the shares are
dissenting shares, or the corporation and the shareholder fail to agree upon the fair market value of the shares, then the shareholder demanding purchase of such shares as dissenting shares or any interested corporation, within six months after the
date on which notice of the approval by the outstanding shares (Section 152) or notice pursuant to subdivision (h) of Section 1110 was mailed to the shareholder, but not thereafter, may file a complaint in the superior court of the proper
county praying the court to determine whether the shares are dissenting shares or the fair market value of the dissenting shares or both or may intervene in any action pending on such a complaint. 

(b) Two or more dissenting shareholders may join as plaintiffs or be joined as defendants in any such action and two or more such actions may be consolidated.

 (c) On the trial of the action, the court shall determine the issues. If the status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in issue, the court shall determine, or shall appoint one or more impartial appraisers to determine, the fair market value of the shares. 

(Amended by Stats. 2012, Ch. 473, Sec. 4. (AB 1680) Effective January 1, 2013.) 

1305. 
 (a) If the court appoints an appraiser or
appraisers, they shall proceed forthwith to determine the fair market value per share. Within the time fixed by the court, the appraisers, or a majority of them, shall make and file a report in the office of the clerk of the court. Thereupon, on the
motion of any party, the report shall be submitted to the court and considered on such evidence as the court considers relevant. If the court finds the report reasonable, the court may confirm it. 

(b) If a majority of the appraisers appointed fail to make and file a report within 10 days from the date of their appointment or within such further time as
may be allowed by the court or the report is not confirmed by the court, the court shall determine the fair market value of the dissenting shares. 
 (c)
Subject to the provisions of Section 1306, judgment shall be rendered against the corporation for payment of an amount equal to the fair market value of each dissenting share multiplied by the number of dissenting shares which any dissenting
shareholder who is a party, or who has intervened, is entitled to require the corporation to purchase, with interest thereon at the legal rate from the date on which judgment was entered. 

  
 3 

 (d) Any such judgment shall be payable forthwith with respect to uncertificated securities and, with respect
to certificated securities, only upon the endorsement and delivery to the corporation of the certificates for the shares described in the judgment. Any party may appeal from the judgment. 

(e) The costs of the action, including reasonable compensation to the appraisers to be fixed by the court, shall be assessed or apportioned as the court
considers equitable, but, if the appraisal exceeds the price offered by the corporation, the corporation shall pay the costs (including in the discretion of the court attorneys’ fees, fees of expert witnesses and interest at the legal rate on
judgments from the date of compliance with Sections 1300, 1301 and 1302 if the value awarded by the court for the shares is more than 125 percent of the price offered by the corporation under subdivision (a) of Section 1301). 

(Amended by Stats. 1986, Ch. 766, Sec. 25.) 
 1306.

 To the extent that the provisions of Chapter 5 prevent the payment to any holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at the legal rate on judgments until the date of payment, but subordinate to all other creditors in any liquidation proceeding, such debt to be payable when permissible under
the provisions of Chapter 5. 
 (Repealed and added by Stats. 1975, Ch. 682.) 

1307. 
 Cash dividends declared and paid by the corporation
upon the dissenting shares after the date of approval of the reorganization by the outstanding shares (Section 152) and prior to payment for the shares by the corporation shall be credited against the total amount to be paid by the corporation
therefor. 
 (Repealed and added by Stats. 1975, Ch. 682.) 

1308. 
 Except as expressly limited in this chapter,
holders of dissenting shares continue to have all the rights and privileges incident to their shares, until the fair market value of their shares is agreed upon or determined. A dissenting shareholder may not withdraw a demand for payment unless the
corporation consents thereto. 
 (Repealed and added by Stats. 1975, Ch. 682.) 

1309. 
 Dissenting shares lose their status as dissenting
shares and the holders thereof cease to be dissenting shareholders and cease to be entitled to require the corporation to purchase their shares upon the happening of any of the following: 

(a) The corporation abandons the reorganization. Upon abandonment of the reorganization, the corporation shall pay on demand to any dissenting shareholder who
has initiated proceedings in good faith under this chapter all necessary expenses incurred in such proceedings and reasonable attorneys’ fees. 

  
 4 

 (b) The shares are transferred prior to their submission for endorsement in accordance with
Section 1302 or are surrendered for conversion into shares of another class in accordance with the articles. 
 (c) The dissenting shareholder and the
corporation do not agree upon the status of the shares as dissenting shares or upon the purchase price of the shares, and neither files a complaint or intervenes in a pending action as provided in Section 1304, within six months after the date
on which notice of the approval by the outstanding shares or notice pursuant to subdivision (h) of Section 1110 was mailed to the shareholder. 

(d) The dissenting shareholder, with the consent of the corporation, withdraws the shareholder’s demand for purchase of the dissenting shares. 

(Amended by Stats. 2012, Ch. 473, Sec. 5. (AB 1680) Effective January 1, 2013.) 

1310. 
 If litigation is instituted to test the sufficiency
or regularity of the votes of the shareholders in authorizing a reorganization, any proceedings under Sections 1304 and 1305 shall be suspended until final determination of such litigation. 

(Repealed and added by Stats. 1975, Ch. 682.) 
 1311.

 This chapter, except Section 1312, does not apply to classes of shares whose terms and provisions specifically set forth the amount to be paid in
respect to such shares in the event of a reorganization or merger. 
 (Amended by Stats. 1988, Ch. 919, Sec. 8.) 

1312. 
 (a) No shareholder of a corporation who has a right
under this chapter to demand payment of cash for the shares held by the shareholder shall have any right at law or in equity to attack the validity of the reorganization or short-form merger, or to have the reorganization or short-form merger set
aside or rescinded, except in an action to test whether the number of shares required to authorize or approve the reorganization have been legally voted in favor thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of a reorganization or short-form merger is entitled to payment in accordance with those terms and provisions or, if the principal terms of the reorganization are approved
pursuant to subdivision (b) of Section 1202, is entitled to payment in accordance with the terms and provisions of the approved reorganization.

reorganization or short-form merger, subdivision (a) shall not apply to any shareholder of such party who has not demanded payment of cash for such shareholder’s shares pursuant to this chapter; but if the shareholder institutes any action
to attack the validity of the reorganization or short-form merger or to have the reorganization or short-form merger set aside or rescinded, the shareholder shall not thereafter have any right to demand payment of cash for the shareholder’s

 This
SUPPORT AGREEMENT (this “Agreement”) is made as of November 21, 2022, by and between CALCIMEDICA, INC., a Delaware
corporation (the “Company”), and the Person set forth on Schedule A hereto (the “Stockholder”). 

WHEREAS, as of the date hereof, the Stockholder is the holder of the number of shares of Common Stock, $0.0001 par value per share
(“Parent Shares”), of GRAYBUG VISION, INC., a Delaware corporation (“Parent”), set forth opposite the Stockholder’s name on
Schedule A (all Parent Shares owned by the Stockholder, or hereafter issued to or otherwise acquired, whether beneficially or of record, prior to the termination of this Agreement, as well as shares set forth on
Schedule A, being referred to herein as the “Subject Shares”); 
 WHEREAS,
concurrently herewith, the Company, Parent and CAMARO MERGER SUB, INC., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”), have
entered into an Agreement and Plan of Merger and Reorganization, dated as of the date hereof (the “Merger Agreement”), which provides, among other things, for the merger of Merger Sub with and into the Company, with the
Company continuing as the surviving company (the “Merger”), upon the terms and subject to the conditions set forth in the Merger Agreement (capitalized terms used but not otherwise defined herein shall have the respective
meanings ascribed to such terms in the Merger Agreement); and 
 WHEREAS, as a condition to its willingness to enter into the Merger
Agreement, the Company has required that the Stockholder, and as an inducement and in consideration therefor, the Stockholder (in the Stockholder’s capacity as a holder of the Subject Shares) has agreed to, enter into this Agreement. 

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth
below and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, do hereby agree as follows: 

ARTICLE I 
 VOTING
AGREEMENT 
 The Stockholder hereby covenants and agrees that: 

1.1. Voting of Subject Shares. From and after the date hereof, at every meeting of the holders of Parent Shares (the
“Parent Stockholders”), however called, and at every adjournment or postponement thereof, the Stockholder shall, or shall cause the holder of record on any applicable record date to, be present (in person or by proxy) and to
vote the Subject Shares (a) in favor of adopting the Merger Agreement and approving the Merger, the other Contemplated Transactions, the Parent Stockholder Matters, and the other actions contemplated by the Merger Agreement, (b) against
approval of any proposal made in opposition to, or in competition with, the Merger Agreement or the consummation of the Merger, and (c) against any Acquisition Proposal with respect to Parent or Merger Sub. The Stockholder (or in the event of a
Transfer of Subject Shares permitted under clauses (A) through (K) of Section 1.2 below, the transferee of such Transferred Subject Shares) shall retain at all times the right to vote the Subject Shares in the
Stockholder’s sole discretion and without any other limitation on those matters other than those set forth in this Section 1.1 that are at any time or from time to time presented for consideration to the Parent
Stockholders. 

 1.2. No Inconsistent Arrangements. Except as provided hereunder or
under the Merger Agreement, prior to the Effective Time, the Stockholder shall not, directly or indirectly, (a) create any Encumbrance other than restrictions imposed by Law or pursuant to this Agreement on any Subject Shares;
(b) transfer, sell, assign, gift or otherwise dispose of (collectively, “Transfer”), or enter into any contract with respect to any Transfer of, the Subject Shares or any interest therein; (c) grant or permit the
grant of any proxy, power of attorney or other authorization in or with respect to the Subject Shares; (d) deposit or permit the deposit of the Subject Shares into a voting trust or enter into a voting agreement or arrangement with respect to
the Subject Shares; or (e) take any action that, to the knowledge of the Stockholder, would have the effect of preventing the Stockholder from performing the Stockholder’s obligations hereunder. Any action taken in violation of the
foregoing sentence shall be null and void ab initio. Notwithstanding the foregoing, the Stockholder may (A) Transfer Subject Shares as a bona fide charitable contribution, gift or donation; (B) Transfer the Subject Shares to
any trust for the direct or indirect benefit of the Stockholder or the immediate family of the Stockholder; (C) Transfer the Subject Shares by will, other testamentary document or intestate succession to the legal representative, heir,
beneficiary or a member of the immediate family of the Stockholder; (D) Transfer the Subject Shares to stockholders, direct or indirect affiliates (within the meaning set forth in Rule 405 under the Securities Act), current or former
partners (general or limited), members or managers of the Stockholder, as applicable, or to the estates of any such stockholders, affiliates, partners, members or managers, or to another corporation, partnership, limited liability company or other
business entity that controls, is controlled by or is under common control with the Stockholder; (E) make Transfers that occur by operation of law pursuant to a qualified domestic relations order or in connection with a divorce settlement,
(F) make Transfers not involving a change in beneficial ownership; (G) if the Stockholder is a trust, Transfer the Subject Shares to any beneficiary of the Stockholder or the estate of any such beneficiary; (H) exercise an option or
warrant to purchase Parent Shares or settle a restricted stock unit or other equity award (including a net or cashless exercise of such option or warrant); (I) Transfer Parent Shares to Parent to cover tax withholding obligations of the
Stockholder in connection with the vesting, settlement or exercise of any options, warrants, restricted stock units or other equity awards, as applicable, provided that the underlying Parent Shares shall continue to be subject to the
restrictions on transfer set forth in this Agreement; (J) establish a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the Transfer of Parent Shares; and (K) Transfer Parent Shares to
Parent pursuant to arrangements under which Parent has the option to repurchase such Parent Shares; provided that, with respect to clauses (A) through (G) above, the transferee agrees in writing to be bound by the terms and
conditions of this Agreement and either the Stockholder or the transferee provides the Company with a copy of such agreement promptly upon consummation of any such Transfer; provided, further that no filing under the
Exchange Act or other public announcement shall be required or shall be made voluntarily in connection with such Transfer (other than filings made in respect of involuntary Transfers); provided that reasonable notice shall be provided
to Parent prior to any such filing and that that the underlying Parent Shares shall continue to be subject to the restrictions on Transfer set forth in this Agreement. For purposes of this Agreement, “immediate family” shall mean any
relationship by blood, marriage or adoption, not more remote than first cousin. 

  
 2 

 1.3. Documentation and Information. The Stockholder shall permit and
hereby authorizes the Company and Parent to publish and disclose in all documents and schedules filed with the SEC, and any press release or other disclosure document that the Company or Parent reasonably determines to be necessary in connection
with the Merger and any of the Contemplated Transactions, the Stockholder’s identity and ownership of the Subject Shares and the nature of the Stockholder’s commitments and obligations under this Agreement. Parent is an intended
third-party beneficiary of this Section 1.3. 
 1.4. Irrevocable Proxy. The Stockholder
hereby revokes (or agrees to cause to be revoked) any proxies that the Stockholder has heretofore granted with respect to the Subject Shares. In the event and to the extent that the Stockholder fails to vote the Subject Shares in accordance with
Section 1.1 at any applicable meeting of the stockholders of Parent or pursuant to any applicable written consent of the stockholders of Parent, the Stockholder shall be deemed to have irrevocably granted to, and appointed, the Company as attorney-in-fact and proxy for and on behalf of the Stockholder, for and in the name, place and stead of the Stockholder, to: (a) attend any and all meetings of Parent
Stockholders with respect to any of the matters specified in Section 1.1, (b) vote, express consent or dissent or issue instructions to the record holder to vote the Subject Shares in accordance with the provisions of Section 1.1 at any
and all meetings of Parent Stockholders or in connection with any action sought to be taken by written consent of Parent Stockholders without a meeting and (c) grant or withhold, or issue instructions to the record holder to grant or withhold,
consistent with the provisions of Section 1.1, all written consents with respect to the Subject Shares at any and all meetings of Parent Stockholders or in connection with any action sought to be taken by written consent of Parent Stockholders
without a meeting. The Company agrees not to exercise the proxy granted herein for any purpose other than the purposes described in this Agreement. The foregoing proxy shall be deemed to be a proxy coupled with an interest, is irrevocable (and as
such shall survive and not be affected by the death, incapacity, mental illness or insanity of the Stockholder, as applicable) until the termination of this Agreement and shall not be terminated by operation of law or upon the occurrence of any
other event other than the termination of this Agreement pursuant to Section 4.2. The Stockholder authorizes such attorney and proxy to substitute any other Person to act hereunder, to revoke any substitution and to file this proxy and any
substitution or revocation with the Secretary of Parent. The Stockholder hereby affirms that the proxy set forth in this Section 1.4 is given in connection with and granted in consideration of and as an inducement to the Company, Parent and
Merger Sub to enter into the Merger Agreement and that such proxy is given to secure the obligations of the Stockholder under Section 1.1. The proxy set forth in this Section 1.4 is executed and intended to be irrevocable, subject,
however, to its automatic termination upon the termination of this Agreement pursuant to Section 4.2. With respect to any Subject Shares that are owned beneficially by the Stockholder but are not held of record by the Stockholder (other than
shares beneficially owned by the Stockholder that are held in the name of a bank, broker or nominee), the Stockholder shall take all action necessary to cause the record holder of such Subject Shares to grant the irrevocable proxy and take all other
actions provided for in this Section 1.4 with respect to such Subject Shares. 
 1.5. No Ownership Interest.
Nothing contained in this Agreement will be deemed to vest in the Company any direct or indirect ownership or incidents of ownership of or with respect to the Subject Shares. All rights, ownership and economic benefits of and relating to the Subject
Shares will remain and belong to the Stockholder, and the Company will have no authority to manage, direct, superintend, restrict, regulate, govern or administer any of the policies or operations of Parent or exercise any power or authority to
direct Stockholder in the voting of any of the Subject Shares, except as otherwise expressly provided herein with respect to the Subject Shares and except as otherwise expressly provided in the Merger Agreement. 

  
 3 

 1.6. No Solicitation of Transactions. The Stockholder hereby agrees
that the Stockholder shall not, directly or indirectly: (a) solicit, initiate or knowingly encourage, induce or facilitate the communication, making, submission or announcement of any Acquisition Proposal or Acquisition Inquiry or take any
action that, to the knowledge of the Stockholder, could reasonably be expected to lead to an Acquisition Proposal or Acquisition Inquiry; (b) furnish any non-public information regarding Parent or any of
its Subsidiaries to any Person in connection with or in response to an Acquisition Proposal or Acquisition Inquiry; (c) engage in discussions (other than to inform any Person of the existence of the provisions in this
Section 1.6) or negotiations with any Person with respect to any Acquisition Proposal or Acquisition Inquiry; (d) approve, endorse or recommend any Acquisition Proposal; (e) execute or enter into any letter of
intent or any Contract contemplating or otherwise relating to any Acquisition Transaction; or (f) publicly propose to do any of the foregoing. The Stockholder hereby represents and warrants that the Stockholder has read Section 4.4 (Parent
Non-Solicitation) of the Merger Agreement and agrees not to engage in any actions prohibited thereby. 

ARTICLE II 

REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDER 

The Stockholder represents and warrants to the Company that: 

2.1. Organization; Authorization; Binding Agreement. The Stockholder, if not a natural person, is duly incorporated or
organized, as applicable, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization. The Stockholder has full legal capacity and power, right and authority to execute and deliver this Agreement and to

contractual or other right or obligation to purchase or otherwise acquire any of the Subject Shares. For purposes of this Agreement “Beneficial Ownership” shall be interpreted as defined in

Person pursuant to any Contract or upon the exercise of conversion rights, exchange rights, warrants or options, or otherwise (irrespective of whether the right to acquire such securities is exercisable immediately or only after the passage of time,
including the passage of time in excess of 60 days, the satisfaction of any conditions, the occurrence of any event or any combination of the foregoing).

2.4. Reliance. The Stockholder has had an opportunity to review with its own tax advisors the tax consequences of the
Merger and the transactions contemplated by the Merger Agreement. The Stockholder understands that it must rely solely on its advisors and not on any statements or representations made by Parent, the Company or any of their respective agents or
representatives. The Stockholder understands that such Stockholder (and not Parent, the Company or the Surviving Corporation) shall be responsible for such Stockholder’s tax liability that may arise as a result of the Merger or the transactions
contemplated by the Merger Agreement. The Stockholder understands and acknowledges that the Company, Parent and Merger Sub are entering into the Merger Agreement in reliance upon the Stockholder’s execution, delivery and performance of this
Agreement.

suit, investigation or proceeding pending against, or, to the knowledge of the Stockholder, threatened in writing against, the Stockholder or any of the Stockholder’s properties or assets (including the Subject Shares) that could reasonably be
expected to prevent, delay or impair the ability of the Stockholder to perform the Stockholder’s obligations hereunder or to consummate the transactions contemplated hereby. 

2.6. Non-Contravention. The execution and delivery of this Agreement by the
Stockholder and the performance of the transactions contemplated by this Agreement by the Stockholder do not and will not violate, conflict with, or result in a breach of: (a) the organizational documents of such Stockholder, (b) any
applicable Law or any injunction, judgment, order, decree, ruling, charge, or other restriction of any Governmental Body to which the Stockholder is subject, or (c) any Contract to which the Stockholder is a party or is bound or to which the

 6 

 
such Person is subject to confidentiality obligations at least as restrictive as those contained herein. Neither the Stockholder nor any of its Affiliates (other than Parent, whose actions shall
be governed by the Merger Agreement) shall issue or cause the publication of any press release or other public announcement with respect to this Agreement, the Merger, the Merger Agreement or the other transactions contemplated hereby or thereby

whom the waiver is to be effective. No failure or delay by either party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise

4.6. Governing Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the
State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws. In any action or proceeding between any of the parties hereto arising out of or relating to this Agreement, each party hereto:
(a) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware or, to the extent such court does not have subject matter jurisdiction, the United States
District Court for the District of Delaware or, to the extent that neither of the foregoing courts has jurisdiction, the Superior Court of the State of Delaware (the “Delaware Courts”); (b) agrees that all claims in
respect of such action or proceeding shall be heard and determined exclusively in accordance with clause (a) of this Section 4.6; (c) waives any objection to laying venue in any such action or proceeding in such

 4.7. Counterparts. This Agreement may be executed in several
counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by all parties by facsimile or electronic transmission
in .PDF format shall be sufficient to bind the parties to the terms and conditions of this Agreement. 
 4.8. Entire
Agreement. This Agreement constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, among or between any of the parties with respect to the subject matter hereof and thereof. 

4.9. Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any
jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final
judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the parties hereto agree that the court making such determination will have the power to limit such term or provision,
to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement
shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable
term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision. 

4.10. Specific Performance. Any and all remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would
occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to
prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any Delaware Court, this being in addition to any other remedy to which they are entitled at law or in equity, and each of the parties hereto waives
any bond, surety or other security that might be required of any other party with respect thereto. 
 4.11.
Construction. 
 (a) For purposes of this Agreement, whenever the context requires: the singular number shall
include the plural, and vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include masculine and feminine genders. 

(b) The parties hereto agree that any rule of construction to the effect that ambiguities are to be resolved against the drafting party
shall not be applied in the construction or interpretation of this Agreement. 
 (c) As used in this Agreement, the words
“include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.” 

  
 8 

 (d) Except as otherwise indicated, all references in this Agreement to
“Sections,” “Articles,” and “Schedules” are intended to refer to Sections or Articles of this Agreement and Schedules to this Agreement, respectively.

Agreement and shall not be referred to in connection with the construction or interpretation of this Agreement. 
 4.12. Further
Assurances. Each of the parties hereto will execute and deliver, or cause to be executed and delivered, all further documents and instruments and use their respective reasonable best efforts to take, or cause to be taken, all actions
and to do, or cause to be done, all things necessary under applicable Law to perform their respective obligations as expressly set forth under this Agreement. 

4.13. Capacity as Stockholder. The Stockholder signs this Agreement solely in the Stockholder’s capacity as a holder
of Parent Shares, and not in the Stockholder’s capacity as a director, officer or employee of Parent or any of its Subsidiaries or in the Stockholder’s capacity as a trustee or fiduciary of any employee benefit plan or trust.
Notwithstanding anything herein to the contrary, nothing herein shall in any way restrict a director or officer of Parent in the exercise of his or her fiduciary duties as a director or officer of Parent or in his or her capacity as a trustee or
fiduciary of any employee benefit plan or trust or prevent or be construed to create any obligation on the part of any director or officer of Parent or any trustee or fiduciary of any employee benefit plan or trust from taking any action in his or
her capacity as such director, officer, trustee or fiduciary. 
 4.14. No Agreement Until Executed. Irrespective of
negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement shall not constitute or be deemed to evidence a contract, agreement, arrangement or understanding between the parties hereto unless and until (a) the
Parent Board has approved, for purposes of any applicable anti-takeover laws and regulations, and any applicable provision of Parent’s Organizational Documents, the Merger, (b) the Merger Agreement is executed by all parties thereto, and
(c) this Agreement is executed by all parties hereto.
