suspension or termination, may be adversely impaired, the consent of such Recipient shall be required or the terms of such Recipient’s Award shall continue to be governed by the Plan and Award Document without giving effect to any such

Options. Incentive Stock Options may be granted only to Eligible Persons meeting the employment requirements of Section 422 of the IRC. 

5.2 Award Documents. Each Award shall be evidenced by an Award Document that shall be in accordance with the provisions of this Plan
setting forth such terms and conditions applicable to the Award. Award Documents may be (but need not be) identical and must comply with and be subject to the terms and conditions of this Plan, a copy of which will be provided to each Recipient and
incorporated by reference into each Award Document. In case of any conflict between this Plan and any Award Document, this Plan shall control. 

5.3 Payment For Awards. 

(a) Payment of Exercise Price. The exercise price or other payment for an Award is payable upon the exercise of a Stock Option or upon
other purchase of shares pursuant to an Award granted hereunder by delivery of legal tender of the United States or payment of such other consideration as the Award Document permits. 

(b) Cashless Exercise. If set forth in the Award Document, the exercise price for Awards may be paid by capital stock of the Company
delivered in transfer to the Company by or on behalf of the person exercising the Award and duly endorsed in blank or accompanied by stock powers duly endorsed in blank, with signatures guaranteed in accordance with the Exchange Act if required by
the Company; or retained by the Company from the stock otherwise issuable upon exercise or surrender of vested and/or exercisable Awards or other equity awards previously granted to the Recipient and being exercised (if applicable) (in either case
valued at Fair Market Value as of the exercise date). 
 5.4 No Employment Rights. Nothing contained in this Plan (or in Award
Documents or in any other documents related to this Plan or to Awards) will confer upon any Eligible Person or Recipient any right to continue in the employ of or engagement by the Company or any Affiliated Entity or constitute any contract or
agreement of employment or engagement, or interfere in any way with the right of the Company or any Affiliated Entity to reduce such person’s compensation or other benefits or to terminate the employment or engagement of such Eligible Person or
Recipient, with or without cause. 
 5.5 Restrictions Under Applicable Laws and Regulations. 

(a) Government Approvals. All Awards will be subject to all applicable registration, listing and qualification requirements. During the
term of this Plan, the Company will use its reasonable efforts to seek to obtain from the appropriate governmental and regulatory agencies any requisite qualifications, consents, approvals or authorizations in order to issue and sell such number of
shares of its Common Stock as is sufficient to satisfy the requirements of this Plan. 
 (b) Recipient Representations. Unless the
issuance of Awards and underlying securities have been registered under the Securities Act and qualified or registered under applicable state securities laws, the Company shall issue the Awards pursuant to applicable exemptions from such
registration or qualification requirements. In connection with any such exempt issuance, the Administrator may require the Recipient to provide a written representation and undertaking to the Company, satisfactory in form and scope to the Company,
that such Recipient is acquiring such Awards and underlying securities for such Recipient’s own account as an investment and not with a view to, or for sale in connection with, the distribution of any such securities, and that such person will

  
 3 

 
make no transfer of the same except in compliance with any rules and regulations in force at the time of such transfer under the Securities Act and other applicable law, and that if securities
are issued without registration, a legend to this effect may be endorsed upon the securities so issued, and to the effect of any additional representations that are appropriate in light of applicable securities laws and rules. The Company may also
order its transfer agent to stop transfers of such shares. 
 5.6 No Rights or Privileges Regarding Stock Ownership or Specific
Assets. Except as otherwise set forth herein, a Recipient or a permitted transferee of an Award will have no rights as a stockholder with respect to any shares issuable or issued in connection with the Award until the Recipient has delivered to
the Company all amounts payable and performed all obligations required to be performed in connection with exercise of the Award and the Company has issued such shares. 

5.7 Non-assignability. No Award is assignable or transferable except: (a) by will or by the laws of descent and distribution; or
(b) upon dissolution of marriage pursuant to a qualified domestic relations order or, transfers for estate planning purposes or pursuant to a nominal transfer that does not result in a change in beneficial ownership. During the lifetime of a
Recipient, an Award granted to such person will be exercisable only by the Recipient (or the Recipient’s permitted transferee) or such person’s guardian or legal representative. 

5.8 Repurchase Rights. Common Stock issued or purchased pursuant to an Award made under the Plan may be subject to such right of
repurchase upon termination of Service of the Recipient or other transfer restrictions as the Administrator may determine consistent with applicable law. Any additional restrictions shall be set forth in an Award Document. 

5.9 Withholding Taxes. Whenever the granting, vesting or exercise of any Award, or the issuance of any Common Stock or other securities
upon exercise of any Award or transfer thereof, gives rise to tax or tax withholding liabilities or obligations, the Company will have the right as a condition thereto to require the Recipient to remit to the Company an amount sufficient to satisfy
any federal, state and local withholding tax requirements arising in connection therewith. The Company may allow satisfaction of tax withholding requirements by accepting delivery of stock of the Company or by withholding a portion of the stock
otherwise issuable in connection with an Award, in each case valued at Fair Market Value as of the date of such delivery or withholding, as the case may be. 

5.10 Legends on Awards and Stock Certificates. Each Award Document and each certificate representing securities acquired upon vesting
or exercise of an Award must be endorsed with all legends, if any, required by applicable federal and state securities and other laws to be placed on the Award Document and/or the certificate. 

5.11 Effect of Termination of Service on Awards. Notwithstanding anything to the contrary herein and except as otherwise provided in an
Award Document, Awards will be exercisable by a Recipient (or the Recipient’s successor in interest) following such Recipient’s termination of Service only to the extent that installments thereof had become exercisable on or prior to the
date of such termination. 
 ARTICLE VI 

AWARDS 
 6.1 Stock
Options. 
 (a) Nature of Stock Options. Stock Options may be Incentive Stock Options or Nonqualified Stock Options. 

(b) Option Exercise Price. The exercise price for each Stock Option will be determined by the Company as of the date such Stock Option
is granted. The exercise price may be equal to or greater than the Fair Market Value of the Common Stock subject to the Stock Option as of the date of grant. 

(c) Exercise of Stock Options. The exercise price for Stock Options will be paid as set forth in Section 5.3. No Stock Option will
be exercisable except in respect of whole shares, and fractional share interests shall be disregarded. Not fewer than 100 shares of Common Stock may be purchased at one time and Stock Options must be exercised in multiples of 100 unless the number
purchased is the total number of shares for which the Stock 

  
 4 

 
Option is exercisable at the time of exercise. A Stock Option will be deemed to be exercised when the Secretary or other designated official of the Company receives written notice of such
exercise from the Recipient in the form of Exhibit A hereto or such other form as the Company may specify from time to time, together with payment of the exercise price in accordance with Section 5.3. 

(d) Special Provisions Regarding Incentive Stock Options. Notwithstanding anything herein to the contrary, 

(i) The exercise price and vesting period of any Stock Option intended to be treated as an Incentive Stock Option must comply with the
provisions of Section 422 of the IRC and the regulations thereunder. As of the Effective Date, such provisions require, among other matters, that: (A) the exercise price must not be less than the Fair Market Value of the underlying stock
as of the date the Incentive Stock Option is granted, and not less than 110% of the Fair Market Value as of such date in the case of a grant to a Significant Stockholder; and (B) that the Incentive Stock Option not be exercisable after the
expiration of ten (10) years from the date of grant or the expiration of five (5) years from the date of grant in the case of an Incentive Stock Option granted to a Significant Stockholder. 

(ii) The aggregate Fair Market Value (determined as of the respective date or dates of grant) of the Common Stock for which one or more Stock
Options granted to any Recipient under this Plan (or any other option plan of the Company or of any Parent Corporation or Subsidiary Corporation) may for the first time become exercisable as Incentive Stock Options under the federal tax laws during
any one calendar year may not exceed $100,000. 
 (iii) Any Stock Options granted as Incentive Stock Options pursuant to this Plan that for
any reason fail or cease to qualify as such will be treated as Nonqualified Stock Options. If the limit described in Section 6.1(d)(ii) is exceeded, the earliest granted Stock Options will be treated as Incentive Stock Options, up to such
limit. 
 6.2 Performance Awards. 

(a) Grant of Performance Award. The Company will determine the pre-established, objective performance goals (which need not be
identical and may be established on an individual or group basis) governing Performance Awards, the terms thereof, and the form and time of payment of Performance Awards. 

(b) Payment of Award. Upon satisfaction of the conditions applicable to a Performance Award, payment will be made to the Recipient in
cash, in shares of Common Stock valued at Fair Market Value as of the date payment is due, or in a combination of Common Stock and cash, as set forth at the time of grant. 

6.3 Restricted Stock. 

(a) Award of Restricted Stock. The Company will determine the Purchase Price (if any), the terms of payment of the Purchase Price, the
restrictions upon the Restricted Stock, and when such restrictions will lapse. 
 (b) Requirements of Restricted Stock. All shares of
Restricted Stock granted or sold pursuant to this Plan will be subject to the following conditions: 
 (i) No Transfer. The shares may not
be sold, assigned, transferred, pledged, hypothecated or otherwise disposed of, alienated or encumbered until the restrictions are removed or expire; 

(ii) Certificates. The Company may require that the certificates representing Restricted Stock granted or sold to a Recipient remain in the
physical custody of an escrow holder or the Company until all restrictions are removed or expire; 
 (iii) Restrictive Legends. Each
certificate representing Restricted Stock granted or sold to a Recipient pursuant to this Plan will bear such legend or legends making reference to the restrictions imposed upon such Restricted Stock as is appropriate to enforce such restrictions;
and 

  
 5 

 (c) Lapse of Restrictions. The restrictions imposed upon Restricted Stock will lapse in
accordance with such terms or other conditions as are set forth at the time of grant. 
 (d) Rights of Recipient. Subject to the
provisions of Section 6.3(b) and any restrictions imposed upon the Restricted Stock, the Recipient will have all rights of a stockholder with respect to the Restricted Stock granted or sold to such Recipient under this Plan, including, without
limitation, the right to vote the shares and receive all dividends and other distributions paid or made with respect thereto. Notwithstanding the foregoing, the Administrator may provide, in an Award Document or otherwise, that any dividends or
distributions paid on Restricted Stock will be subject to the same restrictions applicable to the original Award. 
 6.4 Stock
Appreciation Rights. 
 (a) Granting of Stock Appreciation Rights. The Company may at any time and from time to time approve the
grant to Eligible Persons of Stock Appreciation Rights, related or unrelated to Stock Options. 
 (b) SARs Related to Options. 

(i) A Stock Appreciation Right related to a Stock Option will entitle the holder of the related Stock Option, upon exercise of the Stock
Appreciation Right, to surrender such Stock Option, or any portion thereof to the extent previously vested but unexercised, with respect to the number of shares as to which such Stock Appreciation Right is exercised, and to receive payment of an
amount computed pursuant to Section 6.4(b)(iii). Such Stock Option will, to the extent surrendered, then cease to be exercisable. 

(ii) A Stock Appreciation Right related to a Stock Option hereunder will be exercisable at such time or times, and only to the extent that,
the related Stock Option is exercisable, and will not be transferable except to the extent that such related Stock Option may be transferable (and under the same conditions), will expire no later than the expiration of the related Stock Option, and
may be exercised only when the market price of the Common Stock subject to the related Stock Option exceeds the exercise price of the Stock Option. 

(iii) Upon the exercise of a Stock Appreciation Right related to a Stock Option, the Recipient will be entitled to receive payment of an
amount determined by multiplying: (A) the difference obtained by subtracting the exercise price of a share of Common Stock specified in the related Stock Option from the Fair Market Value of a share of Common Stock on the date of exercise of
such Stock Appreciation Right (or as of such other date or as of the occurrence of such event as may have been specified in the instrument evidencing the grant of the Stock Appreciation Right), by (B) the number of shares as to which such Stock
Appreciation Right is exercised. 
 (c) SARs Unrelated to Options. The Company may grant Stock Appreciation Rights unrelated to Stock
Options. Section 6.4(b)(iii) will govern the amount payable at exercise under such Stock Appreciation Right, except that in lieu of an option exercise price the initial base amount specified in the Award shall be used. 

(d) Payments. Payment of the amount determined under the foregoing provisions may be made solely in whole shares of Common Stock valued
at their Fair Market Value on the date of exercise of the Stock Appreciation Right or, as set forth in the Award Document in cash or in a combination of cash and shares of Common Stock. 

6.5 Stock Bonuses. The Company may issue Stock Bonuses to Eligible Persons on such terms and conditions as the Administrator may
determine. 
 6.6 Phantom Stock. The Company may grant Awards of Phantom Stock to Eligible Persons. Phantom Stock is a cash payment
measured by the Fair Market Value of a specified number of shares of Common Stock on a specified date, or measured by the excess of such Fair Market Value over a specified minimum, which may, but need not, include a provision for crediting of
dividends paid on the Common Stock. 
 6.7 Other Stock-Based Benefits. The Company may grant Other Stock-Based Benefits. Other
Stock-Based Benefits are any arrangements granted under this Plan not otherwise described above that: (a) by their terms might involve the issuance or sale of Common Stock or other securities of the Company; or (b) involve a benefit that
is measured, as a whole or in part, by the value, appreciation, dividend yield or other features attributable to a specified number of shares of Common Stock or other securities of the Company.

 ARTICLE VII 

7.1 Change in Control. As of the effective time and date of any merger or Change in Control, the Recipient will fully vest in and have
the right to exercise all of his or her outstanding Options and Stock Appreciation Rights, including shares of Common Stock as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock, Phantom Stock and
Other Stock-Based Benefits will lapse, and, with respect to Awards with performance-based vesting, all performance goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all other terms and
conditions met. The Administrator will notify the Recipient in writing or electronically that the Option or Stock Appreciation Right will be exercisable for a period of time determined by the Board in its sole discretion, and the Option or Stock
Appreciation Right will terminate upon the expiration of such period. 
 7.2 409A Compliance. Notwithstanding anything in this
Article VII to the contrary, if a payment under an Award Document is subject to Section 409A of the IRC and if the change in control definition contained in the Award Document does not comply with the definition of “change of
control” for purposes of a distribution under Section 409A of the IRC, then any payment of an amount that is otherwise accelerated under this Article will be delayed until the earliest time that such payment would be permissible under
Section 409A of the IRC without triggering any penalties applicable under Section 409A of the IRC. 
 ARTICLE VIIA 

7A.1 Registration of Plan. The Company agrees that whenever it files a registration statement under the Securities Act for an offering

 Exhibit 10.12 

STOCK OPTION AGREEMENT 

THIS STOCK OPTION AGREEMENT (the “Agreement”) is made and entered into as of
            , 2013 (the “Grant Date”), by and between ContraFect Corporation, a Delaware corporation (the “Corporation”), and
                     (the “Optionee”), with an address at
                    . 
 WHEREAS,
the Optionee is a valued [employee][director] of the Corporation; 
 WHEREAS, the Corporation considers it desirable and
in its best interests that Optionee be given an opportunity to acquire a proprietary option to purchase shares of Common Stock of the Corporation, par value $0.0001 per share (the “Shares”) pursuant to the terms and conditions of the
Corporation’s Amended and Restated 2008 Equity Incentive Plan. 
 NOW, THEREFORE, for good and valuable consideration, the
adequacy of which is hereby acknowledged, and the mutual covenants hereinafter set forth, the parties agree as follows: 
 1. Grant of
Option. The Corporation hereby grants to the Optionee the right and option (hereinafter the “Option”) to purchase up to an aggregate of             
(            ) Shares (subject to adjustment as provided in Paragraph 6 hereof), on the terms and conditions set forth herein. The Optionee acknowledges that the Option will not be an
“incentive option” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). 

2. Exercise of Options. The Option granted hereby shall become exercisable by the Optionee at a price per share of
$         (subject to adjustment as provided for herein), as follows: 
  

							
	 Number of Options
	  	Purchase Price per Share	 	  	Date First Exercisable
			
		  	$	            	  	  	
		  	$	            	  	  	
		  	$	            	  	  	

 3. Term of the Option. The Option shall be exercisable as provided in
Paragraph 2 hereof and shall expire on the ten (10) year anniversary of the Grant Date, or upon its earlier termination as provided in this Agreement.  

4. Method of Exercising Option. The Optionee may exercise the Option in whole or in part (to the extent that it is exercisable in
accordance with its terms) by giving written notice to the Corporation in the form annexed hereto as Exhibit A, together with the tender of the full purchase price of the Shares covered by the Option. The purchase price may consist of
(i) cash, (ii) certified or bank check payable to the order of the Corporation in the amount of the purchase price, (iii) a cashless exercise procedure, consisting of authorization from the Optionee to the Corporation to retain from
the total number of Shares as to which the Option is exercised that number of Shares having a Fair Market Value on the date of the exercise equal to purchase price for the total number of Shares as to which the Option is exercised, (iv) other
property or consideration if the Board determines beneficial to the Corporation or (v) any combination of the methods described in (i) through (iv) above. 

As soon as practicable after receipt by the Corporation of such notice and of payment in full of the purchase price of all the Shares with
respect to which the Option has been exercised, a certificate or certificates representing such Shares shall be issued in the name of the Optionee and shall be delivered to the Optionee. All Shares shall be issued only upon receipt by the
Corporation of the Optionee’s representation that the Shares are purchased for investment and not with a view toward distribution thereof. 

5. Availability of Shares. The Corporation, during the term of this Option, shall keep available at all times the number of Shares
required to satisfy the Option. The Corporation shall utilize its best efforts to comply with the requirements of each regulatory commission or agency having jurisdiction in order to issue and sell the Shares to satisfy the Option. 

  
 2 

 6. Adjustments. If prior to the exercise of any portion of the Option granted hereunder
the Corporation shall have effected one or more stock splits, stock dividends, or other increases or reductions of the number of its Shares outstanding without receiving compensation therefor in money, services or property, the number of Shares
subject to the Option hereby granted shall (a) if a net increase shall have been effected in the number of outstanding shares of the Corporation’s Common Stock, be proportionately increased and the purchase price of the Shares issuable
upon exercise of the Option shall be proportionately reduced; and (b) if a net reduction shall have been effected in the number of outstanding shares of the Corporation’s Common Stock, be proportionately reduced and the purchase price of
the Shares issuable upon exercise of the Option shall be proportionately increased. In the event that the Corporation shall make any distribution of its assets upon or with respect to the Shares, as a liquidating dividend, the Optionee shall be
entitled to receive an amount equal to the value thereof at the time of such distribution, less the aggregate purchase price for the Option. 

7. Restrictions. The holder of this Option, by acceptance hereof, represents and warrants as follows: 

(a) This Option and the right to purchase Shares hereunder is personal to the holder and shall not be transferred to any other person, other
than (i) by will or the laws of descent and distribution, or (ii) pursuant to a qualified domestic relations order as defined by the Code, or Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”),
or by the rules thereunder. This Option shall not be collaterally assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process. Any attempted transfer,
assignment, pledge, hypothecation or other disposition of the Option or of any rights granted hereunder contrary to the provisions of this Section 7, or the levy of any attachment or similar process upon the Option or such right, shall be null
and void. 

  
 3 

 (b) The holder hereof has been advised and understands that the Option has been issued in
reliance upon exemptions from registration under the Securities Act and applicable state statutes; the Shares have not been registered under the Securities Act or applicable state statutes and must be held and may not be sold, transferred, or
otherwise disposed of for value unless they are subsequently registered under the Securities Act or an exemption from such registration is available, except as set forth herein; the Corporation is under no obligation to register the Option or the
Shares under the Securities Act or the applicable state statutes; in the absence of such registration, the sale of the Shares may be practicably impossible; the Shares will bear on its face a legend in substantially the following form restricting
the sale of the Shares: 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”) AND ARE “RESTRICTED SECURITIES” WITHIN THE MEANING OF RULE 144 PROMULGATED UNDER THE SECURITIES ACT. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD OR TRANSFERRED WITHOUT
COMPLYING WITH RULE 144 IN THE ABSENCE OF EFFECTIVE REGISTRATION OR OTHER COMPLIANCE UNDER THE SECURITIES ACT. 
 THE SECURITIES
REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFERABILITY AS SET FORTH IN A STOCK OPTION AGREEMENT, A COPY OF WHICH IS ON FILE WITH THE RECORDS OF THE CORPORATION. 

(c) Regardless of whether the offering and sale of Shares have been registered under the Securities Act or have been registered or qualified
under the securities laws of any state, the Corporation at its discretion may impose restrictions upon the sale, pledge or other transfer of such Shares (including the placement of appropriate legends on stock certificates or the imposition of
stop-transfer instructions) if, in the judgment of the Corporation, such restrictions are necessary or desirable in order to achieve compliance with the Securities Act, the securities laws of any state or any other law.

 8. Shareholder’s Rights. This Option is non-transferable by the Optionee, except in
the event of the Optionee’s death as provided in Paragraph 7 hereof and during the Optionee’s lifetime is exercisable only by the Optionee except as provided in Paragraph 7 hereof. The Optionee shall have no rights as a
shareholder with respect to any Shares until payment of the purchase price and delivery to the Optionee of the Shares as provided herein. 

9. Termination of the Option. Upon an Optionee’s termination of Service, any portion of the Option that has not become vested as
of the date of such termination of Service shall immediately be forfeited. Upon an Optionee’s termination of Service for Cause, the entire Option, whether or not vested, shall immediately be forfeited. Upon an Optionee’s termination of
Service for any reason other than Cause, the Optionee shall have two years following such termination of Service to exercise any portion of the Option that has become vested as of the date of such termination of Service; provided, however, that if
the Grant Date of the Option and such termination of Service occurs subsequent to the effective date of the registration statement of the Company’s public offering, the Optionee shall have ninety (90) days to exercise any portion of any
such Option that has become vested as of the date of termination of Service. Notwithstanding the foregoing, each Option to the extent not heretofore exercised shall terminate on the tenth anniversary of the Grant Date. 

10. Right of Repurchase. Following an Optionee’s termination of Service for any reason, the Corporation shall have 60 days from
the date of termination (or, if later, 60 days from the date of exercise of the Option) to exercise an option to purchase all of the Shares that the Optionee has acquired or will acquire under this Option. If the Corporation exercises its right to
purchase the Shares, the Corporation will notify the Optionee of its intention to purchase such Shares, and will consummate the purchase within 60 days of the notice (or such lesser time to the extent required by applicable law). The purchase price
shall be the Fair Market Value of the shares on the date of the Optionee’s termination of Service. The Corporation’s rights of repurchase shall terminate in the event that the Shares are listed on an established national or regional stock
exchange or are publicly traded in an established securities market. 

  
 5 

 11. Lock-Up Agreements. Each Optionee agrees as a condition to receipt of an Option that
the Optionee will not offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or
indirectly, any Common Stock (or other securities) of the Corporation or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other
securities) of the Corporation held by the Optionee (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Corporation not to exceed one hundred
and eighty (180) days following the effective date of any registration statement of the Corporation filed under the Securities Act (or such other period as may be requested by the Corporation or the underwriters to accommodate regulatory
restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE
Rule 472(f)(4), or any successor provisions or amendments thereto). 
 The Optionee further agrees to execute and deliver such other
agreements as may be reasonably requested by the Corporation or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Corporation or the representative of
the underwriters of Common Stock (or other securities) of the Corporation, the Optionee will provide, within ten (10) days of such request, such information as may be required by the Corporation or such representative in connection with the
completion of any public offering of the Corporation’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in this Section 11 will not apply to a registration relating solely to
employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a 

  
 6 

 
registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Corporation may impose stop-transfer instructions
with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred and eighty (180) day (or other) period. The Optionee agrees that any transferee of an Option will be
bound by this Section 11. 
 12. Control by Plan; Validity and Construction. It is understood and agreed that, notwithstanding
anything to the contrary contained herein, in the event of a conflict between the terms of the Plan and this Agreement, the Plan shall control. Capitalized terms used, but not defined herein, shall have the meaning given such terms in the Plan. The
validity and construction of this Option shall be governed by the laws of the State of Delaware. Such construction is vested in the Board and its construction shall be final and conclusive. 

13. No Guaranty. It is understood and agreed that nothing contained in this Agreement, nor any action taken by the Board, shall confer
upon you any right with respect to the continuation of your services to the Corporation or any subsidiary, nor interfere in any way with the right of the Corporation or a subsidiary to terminate your services at any time. 

14. Headings. The headings in this Option are for the purpose of reference only and shall not limit or otherwise affect the meaning of
any provision of this Option. 
 15. Counterparts. This Option may be executed in any number of counterparts, and each such
counterpart shall, for all purposes, be deemed to be an original and all of which together shall constitute one agreement. Facsimile signatures and those transmitted by e-mail or other electronic means shall have the same effect as originals.
