 THIS SEPARATION AGREEMENT (the “Agreement”) is entered into between Sharon Ellis (“Ellis”) and Oxis International, Inc. (the
“Company”) on the dates acknowledged below in order to provide for an orderly and mutually satisfactory transfer of responsibilities, for internal and external communications, and for separation from employment. This is a negotiated
agreement establishing the terms and conditions of Ellis’ separation from employment with the Company and describes and establishes the benefits, terms and conditions of employment between Ellis and the Company except to the extent otherwise
expressly governed by law. 
  

	1.	Meaning of Terms. 

  

	(a)	As used in this Agreement, the “Company” shall mean Oxis International, Inc. and any successor corporation or entity. 

  

	(b)	As used in this Agreement, “Ellis” shall mean Sharon Ellis. 

  

	(c)	As used in this Agreement, “ Resignation Date” shall mean the date on which the Company’s Report on Form 10-QSB for the period ending June 30, 2004 is filed with, and

 The parties acknowledge that this Agreement is entered into in consideration of the mutual promises and covenants herein. 
  

	3.	Resignation as Officer. 

  
 Effective upon the Resignation Date, Ellis will resign as an employee and officer of the Company and its subsidiaries, including without limitation, her position of Chief
Financial Officer. For public knowledge and for purposes of future references, Ellis is resigning both positions, Chief Operating Officer and Chief Financial Officer, effective with the Resignation Date. However, Ellis’s Chief Operating Officer
position officially terminated at the Annual Meeting, June 22, 2004. Ellis acknowledges that she has been and is subject to certain laws governing trading by corporate insiders, and will engage in no trading activities in violation of those laws.
Nothing herein shall limit any right Ellis may have to indemnification for acts as an officer or employee of the Company or for acts done following her resignation as a consultant to the Company, available to her under federal law or the laws of any
state, the Company’s bylaws, and/or Company acquired liability coverage. 

	4.	Resignation. 

  
 Ellis will be employed by the Company until the Resignation Date. Ellis shall thereafter remain entitled to any employment related benefits as granted by the terms of this Agreement and the applicable plans for
post-employment benefits which are vested or to which Ellis is entitled by virtue of this Agreement and the Employment Agreement (defined below).

 Ellis will return any Company property she may have in her possession as soon as possible. Ellis acknowledges that she continues to be bound by Sections 7 of the Employment Agreement (except for Section 7.a (iii) from
which she is released) and agrees to abide by the terms and conditions of such Section. 
  

	6.	Separation Compensation. 

  
 Notwithstanding anything herein to the contrary, and notwithstanding any external or internal statements to the contrary, Ellis’ separation from employment shall be
considered a “Termination by Company not for Cause” under the Employment Agreement dated June 1, 2003 (the “Employment Agreement”) with payments to be made in accordance with the Company’s usual and customary payroll
practices. Ellis shall be entitled to severance at her current annual base salary of $145,000 as stipulated in Section 9a of her Employment Agreement and related post-employment compensation and all other provisions of the Employment Agreement as
applicable to a “Termination by Company not for Cause” (Section 8a). 
  

	7.	Stock. 

  
 Ellis has been the recipient from time to time of grants of stock options. Nothing in this Agreement is intended to affect any rights she may have, or in any way alter the rights and obligations specified in the
option agreements and plan, except that in accordance with the Employment Agreement all unvested options shall vest upon the Resignation Date and she shall thereafter have two years from the Resignation Date to exercise her vested options.

  

	8.	Benefit Plans. 

  
 Except as otherwise provided herein, Ellis’s entitlement to any other benefits afforded by any Company benefit plans are governed solely by their applicable plans and policies and by the provisions of law.

Company on the terms of this Section 9 if she can arrange her time to be available. For such services, Ellis shall be paid a consulting fee of $750 per day or $100 per hour or portion of an hour, in addition to any pay or benefits provided under
this Agreement and she shall be promptly paid upon presentation of her invoice and promptly reimbursed for her reasonable expenses in providing such services. The Company shall hold Ellis harmless and indemnify her for any acts done on the
Company’s behalf during the Consulting Period to the same degree as if she were acting as an executive employee of the Company. 
  

	10.	Non-disparagement and Public Communication. 

  

	(a)	Ellis will not make statements that disparage or malign the reputation or abilities of the Company as it is defined in this Agreement. 

  

	(b)	The Company will not make statements that disparage or malign the reputation or abilities of Ellis. 

  

	(c)	Neither party shall be in breach of this provision as a result of giving truthful testimony in a matter in which the Company is a party or related to a party.

  

	(a)	The parties agree that in publicly discussing Ellis’s separation they will state generally that Ellis has devoted her attentions to advancing the Company through very difficult
times, and that she has decided to turn her attention to other opportunities. 

  

	11.	Releases. 

  
 The parties shall sign such a waiver of claims in connection with the provision of the Employment Agreement in the event of a “Termination by Company not for Cause” which is attached hereto as Exhibit A (the
“Waiver of Claims”). The execution and delivery of the Waiver of Claims (and Ellis not revoking such Waiver of Claims) is an express condition to Ellis receiving any separation compensation referred to herein or the Employment Agreement.

other party concerning such effects.

that this Agreement (together with the documents incorporated by reference or otherwise identified, including the provisions of the Employment Agreement which by their terms continue in effect) states the entire agreement of the Parties and
supersedes all prior and contemporaneous negotiations and agreements, oral or written. 
  

	14.	Severability and Governing Law. 

  
 The Parties agree that any provision of this Agreement that is held to be illegal, invalid, or unenforceable under present or future laws shall be fully severable. The
Parties further agree that this Agreement shall be construed and enforced as if the illegal, invalid, or unenforceable provision had never been a part of this Agreement and the remaining provisions of this Agreement shall remain in full force and
effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance from this Agreement. Furthermore, a provision as similar to the illegal, invalid, or unenforceable provision as is possible and legal, valid,
and enforceable shall be automatically added to this Agreement in lieu of the illegal, invalid, or unenforceable provision. The Parties also agree that Oregon law shall govern the validity and enforceability of this Agreement, and that venue shall
be in the state of Oregon, County of Multnomah. 
  

	15.	Resolution of disputes.

 4Amended and Restated Employment Agreement

 EXHIBIT 10.1 
  
 AMENDED AND RESTATED EMPLOYMENT AGREEMENT 
  
 THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT (this “Agreement”), effective as of the 25th day of May 2004, by
and between CHICAGO MERCANTILE EXCHANGE INC. (“Employer” or “CME”), a Delaware Business Corporation, having its principal place of business at 20 South Wacker Drive, Chicago, Illinois, and David G. Gomach (“Employee”).

  
 R E C I T A L S: 
  
 WHEREAS, Employer wishes to retain the services of Employee in the capacity
of Managing Director, Chief Financial Officer, upon the terms and conditions hereinafter set forth and Employee wishes to accept such employment; 
  
 NOW, THEREFORE, in consideration of the mutual promises contained herein, the parties mutually agree as follows: 
  

	1.	Employment. Subject to the terms of the Agreement, Employer hereby agrees to employ Employee during the Agreement Term (as defined in Section 2 below) as Managing Director,
Chief Financial Officer, and Employee hereby accepts such employment. Employee shall report to Employer’s Chief Executive Officer. The duties of Employee shall include, but not be limited to, the performance of all duties associated with
executive oversight and management of Employer’s Finance Division. 

  
 On Tuesdays, Wednesdays and Thursdays of each work week during the Agreement Term, Employee shall perform his duties hereunder at Employer’s principal place of business in Chicago, Illinois or at such other place
as business travel dictates; provided, however, that Employee may work from his home (or other suitable locations) on such days in the event he cannot travel to Chicago due to inclement weather or personal issues that make travel
impracticable. On Mondays and Fridays of each work week during the Agreement Term, Employee shall perform his duties hereunder at mutually convenient times from his home (or other suitable locations) as necessary to fulfill his duties as Chief
Financial Officer. Subject to the foregoing, Employee shall devote his business time, ability and attention to the business of Employer during the Agreement Term, as directed by the Chief Executive Officer. 
  
 Notwithstanding anything to the contrary contained herein, nothing in the
Agreement shall preclude Employee from participating in the affairs of any governmental, educational or other charitable institution, engaging in professional speaking and writing activities, and serving as a member of the board of directors of a
publicly held corporation (except for a competitor of Employer), provided Employee notifies Employer’s Board of Directors (“Board”) prior to his participating in any such activities and as long as the Board does not determine that any
such activities interfere with or diminish Employee’s obligations under the Agreement. Employee shall be entitled to retain all fees, royalties and other 

 compensation derived from such activities, in addition to the compensation and other benefits payable to
him under the Agreement, but shall disclose such fees to Employer. 
  

	2.	Agreement Term. Employee shall be employed hereunder for a term commencing on May 24, 2004 and ending on December 31, 2005, unless sooner terminated in accordance with
Section 6 below (“Agreement Term”). 

  

	3.	Compensation. 

  

	 	(a)	Base Salary. During the Agreement Term, Employer shall pay to Employee a base salary at a rate of not less than $320,000 per annum (“Base Salary”) payable in
accordance with Employer’s normal payment schedule. 

  

	 	(b)	Bonuses. Subject to this Section 3(b) and Section 6, Employee shall be entitled to receive an annual bonus for 2004 (the “2004 Annual Bonus”). Employee shall be
paid the 2004 Annual Bonus so long as he is employed by Employer on November 1, 2004; provided, however, that Employee shall nonetheless be entitled to receive the 2004 Annual Bonus if at anytime (x) Employee’s employment is
terminated by Employer without Cause or (y) Employee terminates his employment for Good Reason (each as defined in Section 6 below). If Employee is employed on the date Employer customarily pays 2004 bonuses, he shall receive the 2004 Annual Bonus
at such time. The amount of the 2004 Annual Bonus for which the Employee is eligible shall be determined by multiplying $370,673 by a fraction, where the numerator is the number of days elapsed from January 1, 2004 to the last day of the
Employee’s employment with Employer (the “Termination Date”) and the denominator is 365 (in no case shall the fraction exceed 1). The 2004 Annual Bonus shall in no case be paid to Employee later than 30 days following the
Termination Date and shall in all cases be paid in a single lump sum in cash. For 2005 and years thereafter, Employee shall be eligible to receive bonuses at the sole discretion of Employer. 

  

	 	(c)	Equity Awards. Subject to this Section 3(c) and Section 6, Employee shall be entitled, with respect to each equity award which has been granted to Employee prior to the date
hereof which is not fully vested upon the Termination Date, to receive pro rata vesting on the Termination Date of a portion of the shares subject to such award that is subject to vesting during the vesting period in which the Termination Date
occurs (the “Current Tranche”) so long as he is employed by Employer on November 1, 2004; provided, however, that Employee shall nonetheless be entitled to receive the pro rata vesting of each Current Tranche if
Employee’s employment is terminated at anytime (x) by Employer without Cause or (y) Employee terminates his employment for Good Reason (each as defined in Section 6 below). Subject to this Section 3(c), Employee shall be entitled to a

  

 2 

 number of shares of each Current Tranche (and no other tranche) that would have vested following the
Termination Date on the next vesting date for such tranche equal to the number of shares subject to the Current Tranche multiplied by a fraction, the numerator of which shall be the number of days elapsed to the Termination Date since the
date the previous tranche of the award vested and the denominator of which shall be 365 (e.g., certain stock options vested on May 7, 2004 and the next tranche of such award shall vest on May 7, 2005. If Employee’s Termination
Date was January 1, 2005, the numerator would be the number of days elapsed from May 7, 2004 to January 1, 2005 and the denominator would be 365). The terms and conditions of any additional equity grants made to Employee after the date
hereof shall be detailed in the applicable award agreement. For the avoidance of doubt, Exhibit A hereto lists each equity grant held by Employee which is not fully vested as of the date hereof, the vesting dates for such grants and the applicable
tranches. 
  

	 	(d)	Stock Option Exercise Period and Exercise Methods. Notwithstanding anything to the contrary in any Employer plan or any underlying stock option agreement, Employee shall have
2 years from the Termination Date to exercise any vested CME stock options he then holds (including stock options that vest pursuant to Section 3(c)); provided, however, that in no case shall such extension extend the maximum term of
any CME stock option. Employer shall permit Employee to exercise vested CME stock options by tendering previously acquired CME shares (so long as such shares have been held by Employee for at least six months if such shares were acquired from CME)
or by having Employer withhold CME shares otherwise issuable in respect of such awards. Similarly, the Employee shall be permitted to satisfy the minimum statutorily required tax withholding obligations in respect of CME stock options and CME
restricted stock by tendering previously acquired CME shares (so long as such shares have been held by Employee for at least six months if such shares were acquired from CME) or by having Employer withhold CME shares otherwise issuable in respect of
such awards. 

  

	4.	Benefits. 

  

	 	(a)	Employee shall be entitled to insurance, vacation and other employee benefits commensurate with his position in accordance with Employer’s policies for executives in effect
from time to time. 

  

	 	(b)	Between May 24, 2004 and December 31, 2004, Employee shall be entitled to four (4) work weeks (i.e., 12 days) of vacation time in addition to any otherwise accrued but unused
vacation time, three (3) weeks of which may be used during the period from June 21, 2004 to July 16, 2004; provided that Employee shall be reasonably available during those three (3) weeks to assist Employer with closing the books for the
fiscal quarter 

  

 3 

 ending June 30, 2004, releasing its earnings report, meeting with Employer’s audit committee and
preparing for Employer’s earnings conference call. 
  

	5.	Expense Reimbursement. 

  

	 	(a)	During the Agreement Term, Employer shall reimburse Employee, in accordance with Employer’s policies and procedures, for all proper expenses incurred by him in the performance
of his duties hereunder. 

  

	 	(b)	During the Agreement Term, Employer will pay directly or reimburse Employee for (i) round trip airfare between Appleton, Wisconsin and Chicago, Illinois in connection with
Employee’s weekly commute (which currently costs approximately $260.00 per roundtrip) and ground transportation costs between the airport and Employer’s Chicago office; or (ii) use of his personal car in connection with his weekly commute
from Appleton, Wisconsin to Chicago, Illinois at the Internal Revenue Service allowable rate, which is currently 37.5 cents per mile, and costs for parking at Employer’s headquarters. 

  

	 	(c)	Commencing as of July 1, 2004 and continuing until the end of the Agreement Term, Employer will pay directly or reimburse Employee, up to a total of $3000.00 per month, for the
rental of a furnished one bedroom apartment in the Chicago metropolitan area, including parking (or other similar accommodations). Prior to executing a lease for any such apartment, Employee shall provide a copy of the lease to Employer for its
consent which will not be unreasonably withheld. 

  

	 	(d)	Employer shall provide Employee with a full tax gross-up to make him whole to the extent that expenses paid to Employee pursuant to this Section 5 are taxable to him.

  

	6.	Termination. 

  

	 	(a)	Death. Upon the death of Employee, this Agreement shall automatically terminate and all rights of Employee and his heirs, executors and administrators to compensation and
other benefits under this Agreement shall cease, except for compensation which shall have accrued to the date of death, including accrued Base Salary, and other employee benefits to which Employee is entitled upon his death, in accordance with the
terms of the plans and programs of CME. In the event Employee’s employment terminates pursuant to this Section 6(a) after September 1, 2004, his estate or beneficiary shall also be entitled to the bonus and award vesting specified in Section
3(b) and 3(c) of this Agreement. 

  

 4 

	 	(b)	Disability. Employer may, at its option, terminate this Agreement upon written notice to Employee if Employee, because of physical or mental incapacity or disability, fails
to perform the essential functions of his position required of him hereunder for a continuous period of 90 days or any 120 days within any 12-month period. The date of such notice shall be the Termination Date. Upon such termination, all obligations
of Employer hereunder shall cease, except for payment of accrued Base Salary, and other employee benefits to which Employee is entitled upon his termination hereunder, in accordance with the terms of the plans and programs of CME. In the event of
any dispute regarding the existence of Employee’s disability hereunder, the matter shall be resolved as follows: (i) by the determination of a physician selected by the Chief Executive Officer of Employer; (ii) Employee shall have the right to
challenge that determination by presenting a contrary determination from a physician of his choice; (iii) in such event, a physician selected by agreement of the Employee and the Chief Executive Officer of Employer will make the final determination.
The Employee shall submit to appropriate medical examinations for purposes of making the medical determinations hereunder. In the event Employee’s employment terminates pursuant to this Section 6(b) after September 1, 2004, he shall also be
entitled to the bonus and award vesting specified in Section 3(b) and 3(c) of this Agreement. 

  

	 	(c)	Cause. Employer may, at its option, terminate Employee’s employment under this Agreement for Cause. As used in this Agreement, the term “Cause” shall mean any
one or more of the following: 

  

	 	(i)	any refusal by Employee to perform his duties and responsibilities under this Agreement, as determined after investigation by the Board. Employee, after having been given written
notice by Employer, shall have seven (7) days to cure such refusal; 

  

	 	(ii)	any intentional act of fraud, embezzlement, theft or misappropriation of Employer’s funds by Employee, as determined after investigation by the Board, or Employee’s
admission or conviction of a felony or of any crime involving moral turpitude, fraud, embezzlement, theft or misrepresentation; 

  

	 	(iii)	any gross negligence or willful misconduct of Employee resulting in a financial loss or liability to Employer or damage to the reputation of Employer, as determined after
investigation by the Board; 

  

	 	(iv)	any breach by Employee of any one or more of the covenants contained in Section 7 (including Exhibit C hereto) and 8 hereof; 

  

 5 

	 	(v)	any violation of any rule, regulation or guideline imposed by CME or a regulatory or self regulatory body having jurisdiction over Employer, as determined after investigation by the
Board. 

  
 The exercise of the right of CME to
terminate this Agreement pursuant to this Section 6(c) shall be made in writing and shall not abrogate any other rights or remedies of CME in respect of the breach giving rise to such termination. 
  
 If Employer terminates Employee’s employment for Cause, Employee shall
be entitled to accrued Base Salary through the Termination Date and other employee benefits to which Employee is then entitled, in accordance with the terms of the plans and programs of CME. The Termination Date shall be the date of the written
notice to Employee given pursuant to the preceding paragraph. Upon termination for Cause, Employee will forfeit any unvested or unearned compensation or long-term incentives, unless otherwise provided herein or specified in the terms of the plans
and programs of CME. 
  

	 	(d)	Termination Without Cause. Upon 30 days prior written notice to Employee, Employer may terminate this Agreement for any reason other than a reason set forth in sections (a),
(b) or (c) of this Section 6. If, prior to September 1, 2004, Employer terminates the employment of Employee hereunder for any reason other than a reason set forth in subsections (a), (b) or (c) of this Section 6 and provided that, subject to
subsection (g) below, Employee and Employer both execute the release agreement in the form attached hereto as Exhibit B (the “Release Agreement”): 

  

	 	(i)	Employee shall be entitled to receive (i) accrued Base Salary through the Termination Date, (ii) other employee benefits to which Employee is then entitled, in accordance with the
terms of the plans and programs of Employer; and (iii) the bonus and award vesting specified in Section 3(b) and Section 3(c) of this Agreement; and 

  

	 	(ii)	a one time cash lump sum severance payment equal to 24 months of his Base Salary, as defined herein, as of Termination Date. 

  
 If, on or after September 1, 2004, Employer terminates the employment of
Employee hereunder for any reason other than a reason set forth in subsections (a), (b) or (c) of this Section 6, and provided that, subject to subsection (g) below, Employee and Employer both execute the Release Agreement, then Employee shall be
entitled to receive (i) accrued Base Salary through the Termination Date, and (ii) other employee benefits to which Employee is then entitled, in accordance with the terms of the plans and programs of Employer. If Employer terminates the employment
of Employee pursuant to this Section 6(d), Employee shall also be entitled to the bonus and award vesting specified in Section 3(b) and Section 3(c) of this Agreement. 
  

 6 

	 	(e)	Voluntary Termination. Upon 60 days prior written notice to CME (or such shorter period as may be permitted by CME) (the end of such 60-day period or such shorter period
shall be the Termination Date), Employee may voluntarily terminate his employment with CME prior to the end of the Agreement Term for any reason. If Employee voluntarily terminates his employment pursuant to this Section 6(e), and provided that,
subject to subsection (g) below, Employee and Employer both execute the Release Agreement, he shall be entitled to receive (i) accrued Base Salary through the Termination Date; (ii) other employee benefits to which Employee is then entitled, in
accordance with the terms of the plans and programs of CME and as otherwise set forth herein; and (iii) the bonus and award vesting specified in Section 3(b) and Section 3(c) of this Agreement to the extent he has satisfied the requirements
thereunder. 

  

	 	(f)	Resignation with Good Reason. Employee may, at his option, resign from his employment under this Agreement for Good Reason by written notice to the Company without providing
the 60 days prior written notice as required by Section 6(e) at the end of the cure period referred to herein. The Termination Date shall be the date of such notice. As used in this Agreement, the term “Good Reason” shall mean a breach of
this Agreement by Employer or a material and adverse change in Employee’s duties and responsibilities, in either case that is not cured by Employer within fifteen (15) days after receipt of written notice from Employee specifying the alleged
breach or change. If Employee resigns with Good Reason and provided that, subject to subsection (g) below, Employee and Employer both execute the Release Agreement, then Employee shall be entitled to receive (i) accrued Base Salary through the
Termination Date; (ii) other employee benefits to which Employee is then entitled, in accordance with the terms of the plans and programs of Employer and (iii) the bonus and award vesting specified in Section 3(b) and Section 3(c) of this Agreement.

  

	 	(g)	Release Agreement. Employer shall execute the Release Agreement unless Employer reasonably believes that executing such Release Agreement would be inconsistent with its
fiduciary duties to its stockholders under applicable law. In the event Employer executes the Release Agreement, Employee must also execute the Release Agreement as a condition to the receipt of the bonus and award vesting specified in Section 3(b)
and Section 3(c) of this Agreement and the amount set forth in Section 6(d)(ii) of this Agreement. In the event Employer elects to not execute the Release Agreement, Employee shall not be required to execute the Release Agreement and shall
nonetheless be entitled, subject to the other terms and conditions of this Agreement, to the receipt of the bonus and award vesting specified in Section 3(b) and Section 3(c) of this Agreement and the amount set forth in Section 6(d)(ii) of this
Agreement. 

  

 7 

	7.	Confidentiality, Non-Competition and Non-Solicitation. Upon execution of this Agreement, Employee shall also execute the Confidentiality, Non-Competition and Non-Solicitation
Agreement, in the form attached hereto as Exhibit C, which shall be incorporated by reference herein and be made a part hereof. 

  

	8.	Non-Disparagement. Employee will not make any comments to any third parties relating to Employer, or any of its officers or directors, that are critical, derogatory or which
may tend to injure the reputation or business of Employer or any of its officers or directors. Employer will instruct its officers and directors not to make any comments to any third parties relating to Employee that are critical, derogatory or
which may tend to injure the reputation or business of Employee. Nothing in this Agreement shall limit in any manner whatsoever the ability of Employer or Employee to provide truthful and complete information as may be required by any court or
requested by any governmental agency. 

  

	9.	Survival. To the extent necessary to effectuate the terms of this Agreement (including Exhibits hereto), terms of this Agreement which must survive the termination of the
Executive’s employment or the termination of this Agreement shall so survive. 

  

	10.	Restriction on Sale of CME Securities. Until the later of December 4, 2004 or three months following his Termination Date, Employee shall not sell, transfer, encumber, assign
or otherwise dispose of, or agree to sell, transfer, encumber, assign or otherwise dispose of, any CME equity securities or any derivative CME equity securities. Notwithstanding the foregoing, Employee shall be permitted to sell shares of CME common
stock solely to the extent necessary to enable him to (i) exercise CME stock options he holds and (ii) satisfy the statutorily required minimum withholding taxes that arise in connection with any such stock option exercise. Notwithstanding the
foregoing, after December 31, 2005, Employee shall not be subject to the restrictions imposed by the first sentence of this Section 10. 

  

	11.	Claw Back for Violation of Restrictive Covenants. If Employee breaches Section 7 (including Exhibit C hereto, but excluding the provisions thereof relating to
confidentiality) and 8 of this Agreement, Employee (or, if applicable, his beneficiaries or estate) shall promptly, at Employer’s request (i) sell back to Employer all Acquired Shares (as defined below) held by Employee (or, if applicable, his
beneficiaries or estate) as of the date of such breach, for a per share price equal to the price paid by Employee to acquire such shares, and (ii) to the extent such Acquired Shares have previously been sold or otherwise disposed of by Employee,
other than by reason of death (or, if applicable, by his beneficiaries or estate), repay to Employer the excess of (x) the aggregate fair market value of such Acquired Shares calculated based on the applicable closing share price of the

  

 8 

 Company’s common stock on the date of such sale or disposition over (y) the aggregate exercise price
of such Acquired Shares. For purposes of this Section 11, (A) the amount of the repayment described herein shall not be affected by whether Employee (or, if applicable, his beneficiaries or estate) actually received such fair market value with
respect to such sale or other disposition, and (B) repayment may, without limitation, be effected, at the discretion of Employer, by means of offset against any amount owed by Employer to Employee (or, if applicable, his beneficiaries or estate).
For purposes of this Agreement, “Acquired Shares” shall mean shares of Company common stock that were acquired upon exercise of any stock options granted to Employee by Employer that became vested as a result of Section 3(c) hereof. In
addition, if Employee breaches Section 7 (including Exhibit C hereto, but excluding the provisions thereof relating to confidentiality) and 8 of this Agreement he shall, at Employer’s request, promptly repay the 2004 Annual Bonus. 

 

	12.	Arbitration. Except with respect to Sections 7 (including Exhibit C hereto) and 8, any dispute or controversy between CME and Employee, whether arising out of or relating to
this Agreement, the breach of this Agreement, or otherwise, shall be settled by arbitration in Chicago, Illinois, in accordance with the following: 

  

	 	(a)	Arbitration hearings will be conducted by the American Arbitration Association (AAA). Except as modified herein, arbitration hearings will be conducted in accordance with AAA’s
rules. 

  

	 	(b)	State and federal laws contain statues of limitation which prescribe the time frames within which parties must file a law suit to have their disputes resolved through the court
system. These same statutes of limitation will apply in determining the time frame during which the parties must file a request for arbitration. 

  

	 	(c)	If Employee seeks arbitration, Employee shall submit a filing fee to the AAA in an amount equal to the lesser of the filing fee charged in the state or federal court in Chicago,
Illinois. The AAA will bill Employer for the balance of the filing and arbitrator’s fees. 

  

	 	(d)	The arbitrator shall have the same authority to award (and shall be limited to awarding) any remedy or relief that a court of competent jurisdiction could award, including
compensatory damages, attorney fees, punitive damages and reinstatement. Employer and Employee may be represented by legal counsel or any other individual at their own expense during an arbitration hearing. 

  

	 	(e)	Judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. 

  

 9 

	 	(f)	Except as necessary in court proceedings to enforce this arbitration provision or an award rendered hereunder, or to obtain interim relief, neither a party nor an arbitrator may
disclose the existence, content or results of any arbitration hereunder without the prior written consent of CME and Employee. 

  

	13.	Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be deemed given when (i) delivered personally or by overnight

 2. Release. 
  
 (a) The Employee, on behalf of himself, his heirs, executors,
administrators, successors and assigns, hereby irrevocably and unconditionally releases CME and its parents, subsidiaries, divisions and affiliates, together with their respective benefit plans (and their sponsors, fiduciaries and administrators),
owners, assigns, agents, directors, partners, officers, employees, attorneys and representatives and any of their predecessors and successors and each of their estates, heirs and assigns (collectively, the “CME Releasees”) from any
and all charges, complaints, claims, liabilities, obligations, promises, agreements, causes of action, rights, costs, losses, debts and expenses of any nature whatsoever, known or unknown, which the Employee or his heirs, executors, administrators,
successors or assigns ever had, now have or hereafter can, will or may have (either directly, indirectly, derivatively or in any other representative capacity) by reason of any matter, fact or cause whatsoever (i) from the beginning of time to the
date of this Agreement or (ii) relating to his employment with CME or termination thereof. This release includes, without limitation, all claims arising under any federal, state and local labor, employment and/or anti-discrimination laws including,
without limitation, the federal Age Discrimination in Employment Act, Employee Retirement Income Security Act, the Americans with Disabilities Act, Title VII of the Federal Civil Rights Act, the Family and Medical Leave Act, the Illinois Human

 EXHIBIT C 
  
 CONFIDENTIALITY, NON-COMPETITION AND NON-SOLICITATION AGREEMENT 
  
 This Confidentiality, Non-Competition and Non-Solicitation Agreement (the
“Agreement”), is made and entered into this 25th day of May 2004, by and between David G. Gomach (“Employee”) and CHICAGO MERCANTILE EXCHANGE INC. (“Employer” or “CME”), a Delaware Corporation, having its
principal place of business at 20 South Wacker Drive, Chicago, Illinois. 
  
 R E C I T A L S: 
  
 WHEREAS, Employee is
employed by CME in the capacity of Chief Financial Officer; 
  
 WHEREAS, in performing the job functions of Chief Financial Officer, and any subsequent executive or managerial position, Employee has had, and will continue to have, personal contact with CME customers, business partners, and employees,
and Employee has had, and will continue to have, access to CME confidential, proprietary and trade secret information; 
  
 WHEREAS, CME has a legitimate business interest in maintaining its customer and employee relationships and protecting its confidential, proprietary and
trade secret information from disclosure, and Employee acknowledges CME’s legitimate interests in protecting these relationships and this information; 
  
 WHEREAS, Employee is eligible to receive equity in CME pursuant to the Amended and Restated Omnibus Stock Plan and, as a condition to Employee’s
continued eligibility to receive such equity and Employee’s continued employment with CME, Employee agrees to accept certain restrictions on Employee’s activities both during and after employment with CME which protect CME’s
legitimate interests in its customer and employee relationships and confidential, proprietary and trade secret information; 
  
 NOW, THEREFORE, in consideration of such employment, the benefits pertaining thereto, and other mutual promises, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged. 
  
 1. Confidential Information. 
  
 a. Employee acknowledges that the successful development and marketing of CME’s services and products, including CME’s trading programs and systems, current and potential customer and business relationships,
and business strategies and growth and development plans requires substantial effort and expense. Such efforts generate for CME valuable and proprietary information (“Confidential Information”), which gives CME a business advantage over
others who do not have such information. Confidential Information includes, but is not limited to, trade secrets; business plans and proposals; prospect and customer lists; trading methodologies; marketing plans, systems and programs; training
materials; research data bases; computer software; and other technical, business, and financial information of CME not generally known to the public. Employee further acknowledges that during Employee’s employment by the Company, 
  

 C-1 

 Employee’s duties will expose Employee to Confidential Information, and Employee understands and acknowledges that
each and every component of the Confidential Information constitutes a protectible business interest of the Company. 
  
 b. Throughout Employee’s employment with the Company and at all times thereafter: (i) Employee will hold all Confidential Information in the
strictest confidence, take all reasonable precautions to prevent its inadvertent disclosure to any unauthorized person, and follow all CME policies protecting the Confidential Information; (ii) Employee will not, directly or indirectly, utilize,
disclose, or make available to any other person or entity, any of the Confidential Information, other than in the proper performance of Employee’s duties during Employee’s employment with CME; and (iii) if Employee learns that any person
or entity is taking or threatening to take any action which would compromise any Confidential Information, Employee will promptly advise CME of all facts concerning such action or threatened action. 
  
 c. If Employee receives any subpoena or becomes subject to any legal
obligation that might require Employee to disclose Confidential Information, Employee will provide prompt written notice of that fact to CME, enclosing a copy of the subpoena and any other documents describing the legal obligation. In the event that
CME objects to the disclosure of Confidential Information, by way of a motion to quash or otherwise, Employee agrees to not disclose any Confidential Information while any such objection is pending. If, in the absence of a protective order or other
remedy or the receipt of a waiver of compliance with this agreement by CME, Employee is nonetheless, in the written opinion of his counsel, legally compelled to disclose Confidential Information to any tribunal or else stand liable for contempt or
suffer other censure or penalty, Employee may disclose to such tribunal only that portion of the Confidential Information which such counsel advises Employee is legally required to be disclosed, provided that Employee exercises all reasonable
efforts to preserve the confidentiality of the Confidential Information, including, without limitation, by cooperating with CME to obtain an appropriate protective order or other reliable assurance that confidential treatment will be afforded the
Confidential Information by such tribunal. 
  
 d. At the request
of CME (or, without any request, upon termination of Employee’s employment with the Company for any reason), Employee will immediately deliver to CME (i) all property of the Employer that is then in Employee’s possession, custody or
control, including, without limitation, all keys, access cards, credit cards, computer hardware (including but not limited to any hard drives, diskettes, laptop computers and personal data assistants and the contents thereof, as well as any
passwords or codes needed to operate any such hardware), computer software and programs, data, materials, papers, books, files, documents, records, policies, client and customer information and lists, marketing information, design information,
specifications and plans, data base information and lists, mailing lists, notes, and any other property or information that Employee has relating to the Company (whether those materials are in paper or computer-stored form), and (ii) any and all
documents or other items containing, summarizing, or describing any Confidential Information, including all originals and copies. 
  
 2. Non-Competition. For a period of one (1) year following the termination of Employee’s employment with CME for any reason, the
Employee will not (i) be employed in an executive or managerial capacity by, or (ii) provide, whether as an employee, independent contractor, consultant, or otherwise, any services of an 
  

 C-2 

 executive or managerial nature or any services similar to those provided by the Employee to CME during Employee’s
employment with CME to, any derivatives exchange or clearing house. Employee acknowledges that the restrictions contained in this Paragraph 2 are necessary to protect CME’s legitimate interests in its Confidential Information and customer
relationships. 
  
 3. Non-Solicitation of Employees.
Employee agrees that during the term of this Agreement and for a period of one (1) year following the termination of his employment with CME for any reason, Employee shall not employ, retain, solicit, for employment or retention, knowingly assist in
the employment or retention of, or seek to influence or induce to leave CME’s employment or service, any person who is employed or otherwise engaged by CME at any time during the one-year period ending on Employee’s last day of employment
with CME. Employee acknowledges that Employer invests a substantial amount of time and money in recruiting and training, and shares Confidential Information with, its employees. Employee further acknowledges that the restrictions contained in this
Paragraph 3 are necessary to protect CME’s legitimate interests in its Confidential Information and employee relationships. 
  

 C-3 

 4. Assignment of Inventions. 
  
 a. During and after Employee’s employment with CME, Employee will promptly disclose, assign and transfer to CME any
right, title or interest in any inventions, designs, discoveries, works of authorship, creations, developments, improvements or software (collectively, “Inventions”), that Employee may have or acquire, in whole or in part, as a result of
Employee’s employment by CME. This obligation applies to any Inventions that relate to CME’s business, whether or not the Inventions are created, originated, developed or conceived of by Employee solely or jointly with others, or during
business hours or on personal time, and whether or not the Inventions are protected or protectible under applicable patent, trademark, service mark, copyright or trade secret laws. Employee will transfer such Inventions free of all encumbrances and
restrictions, and promptly take any action, including executing and delivering any documentation, deemed necessary by CME to effectuate the transfer or prosecution of ownership rights in the United States and any other country as CME may request.

  
 b. Notwithstanding anything else in this Agreement, Employee
understands that Paragraph 4.a. shall not apply to general know how or to an invention for which no equipment, supplies, facility or trade secret information of CME was used and which was developed entirely on Employee’s own time, unless the
invention (i) relates to the business of CME or CME’s actual or demonstrably anticipated research or development or (ii) results from any work Employee performs or has performed for CME. 
  
 c. Employee acknowledges that any computer programs, documentation, works of
authorship or other copyrightable works that Employee creates in whole or in part during Employee’s employment with CME shall: (i) be considered “works made for hire” under Section 101 of the U.S. Copyright Act, 17 U.S.C. § 101;
(ii) be considered part of the Confidential Information; and (iii) be covered by Paragraph 1 above. 
  
 5. Enforcement. 
  
 a. Employee agrees that given the nature of CME’s business, the scope and duration of the restrictions contained Paragraphs 1 through 5 of this
Agreement are reasonable and necessary to protect the legitimate business interests of CME and do not unduly interfere with Employee’s career or economic pursuits. Employee recognizes and agrees that any breach or threatened or anticipated
breach of any part of Paragraphs 1 through 4 of this Agreement will result in irreparable harm and continuing damage to CME, and that the remedy at law for any such breach or threatened or anticipated breach will be inadequate. Accordingly, in
addition to any other legal or equitable remedies that may be available to CME, Employee agrees that CME shall be entitled to seek and obtain an injunction or injunctions, without bond or other security, to prevent any breach or threatened or
anticipated breach of any such section. Employee agrees to reimburse CME for all costs and expenses, including reasonable attorney’s fees and costs, incurred by CME in connection with the enforcement of its rights under this Agreement.

  
 b. If any part of this Agreement is held void, illegal, or
unenforceable, or in conflict with any applicable law, every other term of this Agreement shall remain valid and fully enforceable. If any court refuses to enforce any part of this Agreement as written, the court shall modify that part to the
minimum extent necessary to make it enforceable under applicable law, and shall enforce it as so modified. CME and 
  

 C-4 

 Employee recognize and agree that this Agreement is not intended to restrict Employee’s activities in violation of
Rule 5.6 of the Illinois Rules of Professional Conduct or any similar rule of another state or court, and if any court refuses to enforce any part of this Agreement as written because that part is deemed to violate Rule 5.6 or any such similar rule,
the court shall modify that part to the minimum extent necessary to make it fully enforceable as to any and all activities not covered by such rule. 
  
 6. Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be deemed given when
(i) delivered personally or by overnight courier to the following address of the other party hereto (or such other address for such party as shall be specified by notice given pursuant to this Paragraph 6) or (ii) sent by facsimile to the following
facsimile number of the other party hereto (or such other facsimile number for such party as shall be specified by notice given pursuant to this Paragraph 6), with the confirmatory copy delivered by overnight courier to the address of such party

dated as of May 25, 2004, constitutes the entire Agreement and understanding between the parties with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or between the parties,

in writing, signed by both parties.

 10. Waivers. The failure of Employer at any time or times to
enforce this Agreement shall in no manner affect its right at a later time to enforce the same. No waiver by Employer of any provision or of any breach of any covenant in this Agreement shall be effective unless in writing signed by the Chief
Executive Officer of CME, and no waiver in any one or more instances shall be deemed to be a further or continuing waiver of any such provision or breach in other instances or a waiver of any other provision or breach of any other provision or
covenant. 
  
 11. Waiver of Jury Trial. EACH PARTY
HERETO WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY DISPUTE RELATING TO OR ARISING OUT OF THIS AGREEMENT, AND AGREES TO TAKE ANY AND ALL ACTION NECESSARY OR APPROPRIATE TO EFFECT SUCH WAIVER.
