6

opinion of the Company’s counsel, such offer, sale or other disposition is exempt from registration or qualification thereunder.  You agree that you shall not offer, sell or otherwise dispose of any Option Shares in any manner which would: (a) require the Company to file any registration statement with the Securities and Exchange Commission (or any similar filing under state law) or to amend or supplement any such filing or (b) violate or cause the Company to violate the Securities Act, the rules and regulations promulgated thereunder or any other state or federal law.  You further understand that the certificates for any Option Shares you purchase shall bear such legends as the Company deems necessary or desirable in connection with the Securities Act or other rules, regulations or laws.

7.             Non-Transferability of Option.  Your Option is personal to you and is not transferable by you other than by will or the laws of descent and distribution.  During your lifetime only you (or your guardian or legal representative) may exercise your Option.  In the event of your death, your Option may be exercised only (a) by the executor or administrator of your estate or the person or persons to whom your rights under the Option shall pass by will or the laws of descent and distribution and (b) to the extent that you were entitled hereunder at the date of your death.

9.             Rights of Participants.  Nothing in this Agreement shall interfere with or limit in any way the right of the Company to terminate your employment at any time (with or without Cause), nor confer upon you any right to continue in the employ of the Company for any period of time or to continue your present (or any other) rate of compensation, and in the event of your termination of employment (including, but not limited to, termination by the Company without Cause), any portion of your Option that was not previously vested and exercisable shall expire and be forfeited, except as otherwise provided herein.  Nothing in this Agreement shall confer upon you any right to be selected again as a Plan participant, and nothing in the Plan or this Agreement shall provide for any adjustment to the number of Option Shares subject to your Option upon the occurrence of subsequent events except as provided in Section 11 below.

10.           Withholding of Taxes.  The Company shall be entitled, if necessary or desirable, to withhold from you from any amounts due and payable by the Company to you (or secure payment from you in lieu of withholding) the amount of any withholding or other tax due from the Company with respect to any Option Shares issuable under this Plan, and the Company may defer such issuance unless indemnified by you to its satisfaction.

7

11.           Adjustments.  In the event of a reorganization, recapitalization, stock dividend or stock split, or combination or other change in the shares of Common Stock, the Board or the Committee shall make such adjustments in the number and type of shares authorized by the Plan, the number and type of shares covered by your Option and the Exercise Price specified herein as may be determined to be appropriate and equitable.  The issuance by the Company of shares of stock of any class, or options or securities exercisable or convertible into shares of stock of any class, for cash or property, or for labor or services either upon direct sale, or upon the exercise of rights or warrants to subscribe therefor, or upon exercise or conversion of other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock then subject to any Options.

12.           Right to Purchase Option Shares Upon Your Termination of Employment.

(a)           Repurchase of Option Shares.  If your employment with the Company shall terminate, including upon your death, Disability, resignation or termination with or without Cause (the date on which such termination occurs being referred to as the “Termination Date”), then the Company shall have the option to repurchase all or any part of the Option Shares issued or issuable upon exercise of your Option, whether held by you or by one or more of your transferees, at the price determined in accordance with the provisions of this Section 12 and Section 13 hereof (the “Repurchase Option”).

(b)           Repurchase by Company.  The Company may elect to purchase all or any portion of the Option Shares by delivery of written notice (the “Repurchase Notice”) to you or any other holders of the Option Shares within 13 months after the Termination Date.  The Repurchase Notice shall set forth the number of Option Shares to be acquired from you and such other holder(s), the aggregate consideration to be paid for such shares and the time and place for the closing of the transaction.  The number of Option Shares to be repurchased by the Company shall first be satisfied to the extent possible from the Option Shares held by you at the time of delivery of the Repurchase Notice.  If the number of Option Shares then held by you is less than the total number of Option Shares the Company has elected to purchase, then the Company shall purchase the remaining shares elected to be purchased from the other holders thereof, pro rata according to the number of shares held by each such holder at the time of delivery of such Repurchase Notice (determined as close as practical to the nearest whole share).

(c)           Repurchase by Investors.  If for any reason the Company does not elect to purchase all of the Option Shares pursuant to the Repurchase Option, then the Investors shall be entitled to exercise the Company’s Repurchase Option in the manner set forth in this Section 12 for all or any portion of the number of Option Shares the Company has not elected to purchase (the “Available Shares”).  As soon as practicable after the Company has determined that there shall be Available Shares, but in any event within 13 months after the Termination Date, the Company shall deliver written notice (the “Option Notice”) to the Investors setting forth the number of Available Shares and the price for each Available Share.  The Investors may elect to purchase any number of Available Shares by delivering written notice to the Company within 20

8

days after receipt of the Option Notice from the Company.  As soon as practicable, and in any event within five days after the expiration of such 20-day period, the Company shall notify you and any other holder(s) of Option Shares as to the number of Option Shares being purchased from you by the Investors (the “Supplemental Repurchase Notice”).  At the time the Company delivers the Supplemental Repurchase Notice to you and such other holder(s) of Option Shares, the Investors shall also receive written notice from the Company setting forth the number of shares they are entitled to purchase, the aggregate purchase price and the time and place of the closing of the transaction.

(d)           Closing of Repurchase of Option Shares.  The purchase of Option Shares pursuant to this Section 12 shall be closed at the Company’s executive offices within 60 days after the expiration of the 13 months period referred to in Section 12(b).  At the closing, the purchaser or purchasers shall pay the purchase price in the manner specified in Section 13(b) and you and any other holders of Option Shares being purchased shall deliver the certificate or certificates representing such shares to the purchaser or purchasers or their nominees, accompanied by duly executed stock powers.  Any purchaser of Option Shares under this Section 12 shall be entitled to receive customary representations and warranties from you and any other selling holders of Option Shares regarding the sale of such shares (including representations and warranties regarding good title to such shares, free and clear of any liens or encumbrances) and to require all sellers’ signatures to be guaranteed by a national bank or reputable securities broker.

13.           Purchase Price for Option Shares.

(a)           Purchase Price.  The purchase price per share to be paid for the Option Shares purchased by the Company and the Investors pursuant to Section 12 shall be equal to the Fair Market Value of such Option Shares as of the Termination Date; provided that if your employment with the Company terminates due to a resignation by you without Good Reason or your discharge by the Company for Cause, then the purchase price per share to be paid for the Option Shares purchased by the Company and the Investors pursuant to Section 12 shall be equal to the lower of (i) the Exercise Price of such Option Shares or (ii) the Fair Market Value of such Option Shares as of the Termination Date.

(b)           Manner of Payment.  If the Company purchases all or any portion of such Option Shares, including Option Shares held by one or more transferees, then the Company shall pay for such Option Shares by check or wire transfer of funds; provided that, if such cash payment would (i) cause the Company to violate state or federal securities laws, or the General Corporation Law of the State of Delaware, or (ii) cause the Company to breach any agreement to which it is a party relating to the indebtedness for borrowed money or any other material agreement ((i) and (ii) are collectively referred to as the “Reasons for Deferral”), then the Company shall have the right to pay such amount within 30 days after no Reason for Deferral exists so long as the Company also pays interest at the “prime rate” as listed in The Wall Street Journal in its “Money Rates” section on the Date of Termination (or if no such rate is published

9

on such date, on the latest preceding date on which such rate is published) for the deferral period at the time when such payment is made.  Alternatively, if and to the extent any such laws or restrictions prohibit the repurchase of Option Shares hereunder for cash, the Company may, at its sole option, repurchase such Option Shares, in which case the amount of the purchase price which is not able to be paid in cash shall be paid for by the issuance of a subordinated promissory note, which, subject to the approval of the senior lender(s) of the Company, shall be payable as soon as the Company is permitted to pay such note under such laws or restrictions and shall bear interest (payable annually) at a rate per annum equal to the “prime rate” as listed in The Wall Street Journal in its “Money Rates” section on the date such note is issued.  If the Investors elect to purchase all or any portion of the Available Shares, the Investors shall pay for such Option Shares by certified check or wire transfer of funds.

14.           Restrictions on Transfer.

(a)           Transfer of Option Shares. The holders of Option Shares shall not sell, transfer, assign, pledge, or otherwise dispose of (whether with or without consideration and whether voluntarily or involuntarily or by operation of law) (a “Transfer”) any interest in any Option Shares without the prior written consent of the Company, except pursuant to (i) a Sale of the Company, (ii) a repurchase pursuant to Sections 12 and 13 above or (iii) the provisions of Section 14(b) hereof.

(b)           Certain Permitted Transfers.  The restrictions set forth in this Section 14 shall not apply with respect to any Transfer of Option Shares made (i) pursuant to applicable laws of descent and distribution or to such person’s legal guardian in case of any mental incapacity or among such person’s Family Group, or (ii) at such time as the Investors sell Common Shares in a Public Sale, but in the case of this clause (ii) only to extent of the number of Option Shares held by you multiplied by a fraction, the numerator of which is the number of Common Shares sold by the Investors in such Public Sale and the denominator of which is the total number of Common Shares held by the Investors prior to the Public Sale; provided, that the restrictions contained in this Section 14 will continue to be applicable to the Option Shares after any Transfer of the type referred to in clause (i) and the transferees of such Option Shares will agree in writing to be bound by the provisions of this Agreement. Any transferee of Option Shares pursuant to a transfer in accordance with the provisions of this Section 14(b) is herein referred to as a “Permitted Transferee.” Upon the transfer of Option Shares pursuant to this Section 14(b), you will deliver a written notice (a “Transfer Notice”) to the Company. In the case of a Transfer pursuant to clause (i) hereof, the Transfer Notice will disclose in reasonable detail the identity of the Permitted Transferee(s).

(c)           Termination of Restrictions. The restrictions set forth in this Section 14 will continue with respect to each Option Share until the earlier of (i) the date on which such Option Share has been transferred in a Public Sale in compliance with the terms hereof, (ii) the date on which such Option Share is repurchased pursuant to Section 12 and 13 above and (iii) the consummation of a Sale of the Company.

10

15.           Sale of the Company.

(a)           If the Board and the holders of a majority of the shares of Common Stock then outstanding approve a Sale of the Company to an Independent Third Party (an “Approved Sale”), each holder of Option Shares entitled to vote thereon shall vote for, consent to and raise no objections against such Approved Sale.  If the Approved Sale is structured as a (i) merger or consolidation, each holder of Option Shares shall waive any dissenters’ rights, appraisal rights or similar rights in connection with such merger or consolidation or (ii) sale of stock, each holder of Option Shares shall agree to sell all of his Option Shares and rights to acquire equity securities of the Company on the terms and conditions approved by the Board and the holders of a majority of the Common Stock then outstanding; provided that such terms and conditions are no less favorable to the Minority Stockholders than the terms and conditions applicable to CHS and its Affiliates and; provided further that CHS may require you to sell the same percentage of your securities as CHS is selling of its securities, on the same terms as CHS and its Affiliates.  Each holder of Option Shares shall take all necessary or desirable actions in connection with the consummation of the Approved Sale as reasonably requested by the Company.

(b)           The obligations of the holders of Option Shares with respect to the Approved Sale of the Company are subject to the satisfaction of the following conditions: (i) upon the consummation of the Approved Sale, each holder of Option Shares (in his, her or its capacity as such) shall have the right to receive the same form of consideration and the same amount of consideration per share for each class of Option Shares held by such holder applicable to each class; (ii) if any holders of a class of Option Shares are given an option as to the form and amount of consideration to be received or any other right or benefit with respect to the Approved Sale, each holder of such class of Option Shares shall be given the same option, right or benefit (other, in the case of clause (i) or this clause (ii), than any option, right or benefit to be received by a stockholder on account of such person’s employment relationship with the Company (e.g., stay bonus, noncompetition agreement, right to reinvest or roll over equity, etc.)); and (iii) each holder of then currently exercisable rights to acquire shares of a class of Option Shares shall be given an opportunity to either (A) exercise such rights prior to the consummation of the Approved Sale and participate in such sale as holders of such class of Option Shares or (B) upon the consummation of the Approved Sale, receive in exchange for such rights consideration equal to the amount determined by multiplying (1) the same amount of consideration per share of a class of Option Shares received by holders of such class of Option Shares in connection with the Approved Sale less the exercise price per share of such class of Option Shares of such rights to acquire such class of Option Shares by (2) the number of shares of such class of Option Shares represented by such rights.

(c)           Each stockholder will bear his, her or its pro rata share (based upon the number of shares of Common Stock to be sold) of the reasonable out-of-pocket costs of any sale of Option Shares pursuant to an Approved Sale to the extent such costs are incurred for the benefit of all such holders of the Company’s capital stock and are not otherwise paid by the Company or the acquiring party.  Costs incurred by the holders of the Company’s capital stock

11

on their own behalf will not be considered costs of the Approved Sale.  Each person transferring Option Shares pursuant to an Approved Sale shall be obligated, severally, not jointly, to join on a pro rata basis (based on the number of shares of Common Stock to be sold) in any indemnification or other obligations that are part of the terms and conditions of the Approved Sale (other than any such obligations that relate specifically to a particular stockholder, such as indemnification with respect to representations and warranties given by a stockholder regarding such stockholder’s title to and ownership of Option Shares) (the “Company Indemnity Obligations”).  Notwithstanding the foregoing, no stockholder shall be obligated in connection with any Approved Sale to agree to indemnify or hold harmless the transferees with respect to Company Indemnity Obligations in an amount in excess of the net proceeds paid to such stockholder in connection with the Approved Sale.

(d)           In the event of a sale or exchange by the holders of the Company’s capital stock of all or substantially all of the Company’s capital stock by sale, merger, recapitalization, reorganization, consolidation, combination or otherwise, including an Approved Sale, the Company and each holder of Option Shares shall take all necessary and desirable actions in order that each holder of Option Shares shall receive in exchange for such holder’s Option Shares the same portion of the aggregate consideration from such sale or exchange that such holder would have received if such aggregate consideration had been distributed by the Company in complete liquidation pursuant to the rights and preferences set forth in the Company’s Certificate of Incorporation as in effect immediately prior to such sale or exchange.

(e)           If the Company or the holders of the Company’s securities enter into any negotiation or transaction for which Rule 506 (or any similar rule then in effect) promulgated by the Securities and Exchange Commission may be available with respect to such negotiation or transaction (including a merger, consolidation or other reorganization), you shall, at the request of the Company, appoint a purchaser representative (as such term is defined in Rule 501) reasonably acceptable to the Company.  If you appoint the purchaser representative designated by the Company, the Company shall pay the fees of such purchaser representative, but if you decline to appoint the purchaser representative designated by the Company you shall appoint another purchaser representative (reasonably acceptable to the Company), and you shall be responsible for the fees of the purchaser representative so appointed.

(f)            In order to secure each the obligation of each holder of Option Shares to vote his Option Shares entitled to vote thereon and other voting securities of the Company in accordance with the provisions of this Section 15, each holder of Option Shares who is an individual hereby appoints each CHS Director (as defined in the Stockholders Agreement, and as in effect from time to time) as his true and lawful proxy and attorney-in-fact, with full power of substitution, to vote all of his Option Shares and other voting securities of the Company for the matters expressly provided for in this Section 15.  Each CHS Director may exercise the irrevocable proxy granted to him hereunder at any time any holder of Option Shares who is an individual fails to comply with the provisions of this Section 15.  The proxies and powers granted by each holder of Option Shares who is an individual pursuant to this Section 15(f) are

12

coupled with an interest and are given to secure the performance of the obligations of such holder of Option Shares under this Section 15.  Such proxies and powers shall be irrevocable and shall survive the death, incompetency, disability or bankruptcy of such holder of Option Shares and the subsequent holders of his, her or its Option Shares.

16.           Additional Restrictions on Transfer.

(a)           Restrictive Legend.  The certificates representing the Option Shares shall bear the following legend:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY ISSUED ON                 , HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS OR AN EXEMPTION FROM REGISTRATION THEREUNDER.  THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER, CERTAIN REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH IN AN OPTION AGREEMENT BETWEEN THE COMPANY AND AND AN EXECUTIVE OF THE COMPANY, DATED AS OF               , 2009, A COPY OF WHICH MAY BE OBTAINED BY THE HOLDER HEREOF AT THE COMPANY’S PRINCIPAL PLACE OF BUSINESS WITHOUT CHARGE.”

(b)           Opinion of Counsel.  You may not sell, transfer or dispose of any Option Shares (except pursuant to an effective registration statement under the Securities Act) without first delivering to the Company an opinion of counsel reasonably acceptable in form and substance to the Company that registration under the Securities Act or any applicable state securities law is not required in connection with such transfer.

(c)           Holdback.  You agree not to offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any Option Shares or other equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of such securities, whether any such aforementioned transaction is to be settled by delivery of such securities or other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, in each case during the seven days before and the 90-day period (but in the case of the Company’s initial public offering, the 180-day period) beginning on the effective date of any underwritten public offering of the Company’s equity securities (or such longer or shorter

13

period (but not in excess of 180 days) as may be requested in writing by the managing underwriter and agreed to in writing by the Company) (the “Market Standoff Period”), except as part of such underwritten registration if otherwise permitted.  In addition, you agree to execute any further letters, agreements and/or other documents requested by the Company or its underwriters which are consistent with the terms of this Section 16(c).  The Company may impose stop transfer instructions with respect to securities subject to the foregoing restrictions until the end of such Market Standoff Period.

17.           Remedies.  The parties hereto (and the Investors as third-party beneficiaries) shall be entitled to enforce their rights under this Agreement specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor.  The parties hereto acknowledge and agree that money damages would not be an adequate remedy for any breach of the provisions of this Agreement and that any party hereto (and any Investor as a third-party beneficiary) shall be entitled to specific performance and/or injunctive relief (without posting bond or other security) from any court of law or equity of competent jurisdiction in order to enforce or prevent any violation of the provisions of this Agreement.

18.           Amendment.  Except as otherwise provided herein, any provision of this Agreement may be amended or waived only with the prior written consent of you and the Company; provided that no provision of Section 1, 12, 13, 14, 15, 16 or 17 or of this Section 18 may be amended or waived without the prior written consent of the Investors.

19.           Successors and Assigns.  Except as otherwise expressly provided herein, all covenants and agreements contained in this Agreement by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors and permitted assigns of the parties hereto whether so expressed or not.

20.           Severability.  Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement.

21.           Counterparts.  This Agreement may be executed simultaneously in any number of counterparts and may be delivered by means of facsimile or comparable electronic transmission, each of which shall constitute an original, but all of which taken together shall constitute one and the same Agreement.

22.           Descriptive Headings.  The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement.

23.           Governing Law.  The corporate law of Delaware shall govern all questions concerning the relative rights of the Company and its stockholders.  All other questions

14

concerning the construction, validity and interpretation of this Agreement shall be governed by the internal law, and not the law of conflicts, of Illinois.

24.           Notices.  All notices, demands or other communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given when delivered personally or mailed by certified or registered mail, return receipt requested and postage prepaid, to the recipient.  Such notices, demands and other communications shall be sent to you and to the Company and the Investors at the addresses indicated below:

CONSENT

The undersigned spouse of Mark C. Arnold hereby acknowledges that I have read the foregoing Stock Option Agreement and that I understand its contents.  I am aware that the Agreement provides for the repurchase of my spouse’s shares of Common Stock under certain circumstances and imposes other restrictions on the transfer of such Common Stock.  I agree that my spouse’s interest in the Common Stock is subject to this Agreement and any interest I may have in such Common Stock shall be irrevocably bound by this Agreement and further that the my community property interest, if any, shall be similarly bound by this Agreement.

I am aware that the legal, financial and other matters contained in this Agreement are complex and I am free to seek advice with respect thereto from independent counsel.  I have either sought such advice or determined after carefully reviewing this Agreement that I will waive such right.
