Seller’s Representations, Warranties and Covenants

As of the date hereof, Seller is not in possession of any material nonpublic information concerning the Issuer or its securities and is not subject to any legal, regulatory, or contractual restriction or undertaking that would prevent Stifel from conducting the trading plan in accordance with the Sales Plan. Seller is entering into this Sales Plan in good faith (and will act in good faith for the duration of the Sales Plan) and not as part of a plan or scheme to evade compliance with the federal securities laws, including Rule 10b5-1 of the Exchange Act.

The securities to be sold under this Sales Plan are owned free and clear by Seller (subject, in the case of shares underlying Options or Awards, only to the compliance by Seller with the exercise provisions of such Options or vesting provisions of such Awards) and are not subject to any liens, claims, charges, security interests or other encumbrances or limitations on disposition (e.g., a lock- up agreement) other than those that may be imposed by Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”).

While this Sales Plan is in effect, Seller agrees not to enter into or alter any corresponding or hedging transaction or position with respect to the securities covered by this Sales Plan and agrees not to alter or deviate from, or attempt to exercise any influence over how, when or whether transactions are executed pursuant to, the terms of this Sales Plan.

Seller agrees to:

provide Stifel prior to commencement of the Plan Sales Period (as defined below) with an executed representation letter from the Issuer substantially in the form of Exhibit A .

The Seller agrees to notify Stifel in writing if he or she becomes subject to a legal, regulatory, contractual or other restriction that would cause transactions pursuant to the Sales Plan to violate or conflict with any such law, regulation, Employee Plan, Insider Plan, policy, contract, judgment, order, decree or undertaking. The Seller further certifies that any consents required to be obtained with respect to the Sales Plan under any such law, regulation, Employee Plan, Insider Plan, policy, contract, judgment, order, decree or undertaking have been obtained and are in full force and effect and that the Seller is in full compliance with any and all such conditions and has obtained any and all such consents.

If the Stock is to be sold under Rule 144:

Seller agrees not to take, and agrees not to cause any person or entity with which Seller would be required to aggregate sales of Stock pursuant to paragraph (a)(2) or (e) of Rule 144 to take any action that would cause the sales under this Sales Plan not to meet all applicable requirements of Rule 144.

Seller agrees to complete, execute and deliver to Stifel Forms 144 for the sales to be effected under this Sales Plan at such times and in such number of copies as Stifel shall request. Seller authorizes Stifel to maintain pre-signed Forms 144 in safekeeping and to complete and file these forms as necessary on behalf of Seller to effect Sales under the Sales Plan.

Seller agrees to complete, execute and deliver to Stifel a representation letter substantially in the form of Exhibit B to this Sales Plan prior to the commencement of the Plan Sales Period (as defined below).

Implementation of the Plan

Seller hereby authorizes Stifel to execute the following transaction(s) on behalf of the Seller in accordance with the following terms set forth herein and in Schedule A:

Stifel is authorized to begin selling Stock under this Sales Plan a minimum of (Select one of the following):

Stifel shall sell the Quantity (as defined in Schedule A) for the account of Seller, subject to the restrictions and parameters set forth in Schedule A of this Sales Plan. A “Trading Day” is defined as any day during the Plan Sales Period that the Principal Market is open for business.

Subject to the restrictions and parameters set forth in Schedule A of this Sales Plan, Stifel shall sell the Quantity of Shares set forth in Schedule A under ordinary principles of best execution at the then-prevailing market price. Unless otherwise specified, Stifel will execute the Seller’s order on a “Not Held” basis. Not Held orders are market or limit orders that give the Stifel trader the right to use reasonable brokerage judgment, exercising price and time discretion, as to when to execute the order under the Sales Plan.

Seller agrees and acknowledges that Stifel may execute Seller’s order(s): (i) in a single transaction or multiple transactions during the course of one or more Trading Day(s), or (ii) by aggregating the order with other orders for other sellers of the Issuer’s securities that may or may not have been accepted pursuant to a Rule 10b5-1 plan, executing them as a block or multiple smaller transactions, and allocate an average price to each seller.

The Quantity and the Minimum Sale Price set forth in Schedule A, if applicable, shall be adjusted automatically on a proportionate basis to take into account any stock split, reverse stock split or stock dividend with respect to the Stock or any change in capitalization with respect to the Issuer that occurs during the Plan Sales Period. Stifel will not sell fractional shares under this Sales Plan. In the event that the above referenced adjustment of Quantity results in fractional shares, the Quantity will be rounded down to the nearest whole number.

Seller agrees to the following with regard to Stock:

If the Sales Plan includes Owned Shares, Seller agrees to deliver the total Stock (not to include shares that are to be acquired through the exercise of Options and/or Awards pursuant to this Sales Plan), into an account at Stifel in the name of and for the benefit of Seller (the “Plan Account”) and that Stock will be in street name, electronically transferable form, without legend or stop transfer within the Plan Account prior to the close of the Principal Market on the business day preceding the commencement of sales under this Sales Plan, and Stifel shall have the discretion to terminate this Sales Plan if any of the above requirements is not met.

If this Sales Plan includes Option Shares, Seller agrees to make appropriate arrangements with the Issuer and its transfer agent and stock plan administrator to permit Stifel to furnish notice to the Issuer of the exercise of the Options and to have the underlying Stock delivered to Stifel as necessary to settle sales under this Sales Plan. Seller hereby authorizes Stifel to serve as Seller’s agent and attorney-in-fact and, in accordance with the terms of this Sales Plan, to exercise the Options. Stock received upon exercise of Options shall be delivered to a Stifel account in the name of and for the benefit of Seller (the “Plan Account”).

Stifel shall in no event exercise any Option if at the time of exercise the exercise price of the Option is equal to or higher than the market price of the Stock.

Stifel shall, in connection with the exercise of Options; remit to the Issuer the exercise price of the Options along with such amounts as may be necessary to satisfy withholding obligations. These amounts shall be deducted from the proceeds of sale of the underlying Stock, together with interest, if applicable, and other transaction expenses thereon computed in accordance with Stifel’s customary practices.

If this Sales Plan includes Awards Shares, Seller agrees to make appropriate arrangements with the Issuer and its transfer agent and stock plan administrator to permit Stifel to furnish notice to the Issuer of the sale of Shares to finance taxes for the applicable grant and to have the underlying Stock delivered to Stifel as necessary to settle sales under this Sales Plan. Seller hereby authorizes Stifel to serve as Seller’s agent and attorney-in-fact and, in accordance with the terms of this Sales Plan, to pay for the taxes due upon the vesting of Restricted Stock Units, Restricted Stock Awards or Performance Awards. Stock received upon vesting of Awards Shares and payment of taxes shall be delivered to a Stifel account in the name of and for the benefit of Seller (the “Plan Account”)

Stifel shall, in connection with the sale of Shares to cover taxes due upon vesting of Awards Shares; remit to the Issuer the taxes due upon vesting as determined by the Issuer. These amounts shall be deducted from the proceeds of sale of the underlying Stock, together with interest, if applicable, and other transaction expenses thereon computed in accordance with Stifel’s customary practices

To the extent that any Stock from which restrictions were removed remain in the Plan Account after the end of the Plan Sales Period or upon termination of this Sales Plan, Stifel agrees that it will contact Issuer regarding the issuance of a letter instructing the transfer agent to reissue the unsold shares in the name of the Seller bearing the original restrictive legend.

Suspension.

Seller agrees that Stifel may suspend sales under this Sales Plan as soon as practicable after:

trading of the Stock on the Principal Market on which the Stock trades is suspended for any reason;

Stifel, in its sole discretion, determines that there is a legal, regulatory or contractual reason why it cannot effect a sale of Stock; or

Stifel has received written notice from Seller or Issuer that there is a legal, regulatory or contractual restriction applicable to Seller or Issuer that would prevent the sale of Stock under this Sales Plan.

Stifel will resume sales under this Sales Plan as soon as practicable after (i) Stifel has received written notice from Seller or Issuer that the restriction covered by paragraph D.1.c has been lifted or (ii) Stifel determines, in its sole discretion, that it may resume sales in accordance with this Sales Plan in the case of an occurrence of an event described in paragraph D.1.a or D.1.b

Upon the resumption of trading, as defined in Schedule A, any orders having a parameter end date scheduled to have occurred during the suspension period shall be deemed to have expired. Any orders having a parameter start date scheduled to have occurred during the suspension period shall be placed as soon as practicable for the balance of time remaining until the applicable parameter end date. All other orders shall be placed as originally indicated in this Sales Plan.

Termination

This Sales Plan shall terminate on the earliest of:

the close of business on Plan Termination Date;

the date on which all shares are sold, as applicable, pursuant to the Sales Plan;

the date on which Stifel receives notice of the death of the Seller or the commencement of any proceedings in respect of or triggered by the Seller’s bankruptcy or insolvency;

at Stifel’s discretion, the date of public announcement of merger, acquisition, reorganization, recapitalization or comparable transaction involving the Issuer;

the date of public announcement of the voluntary or involuntary liquidation, bankruptcy, insolvency or nationalization of, or any analogous proceeding affecting the Issuer;

in the event the Sales Plan consists entirely of Options Shares, the date on which all of the Options Shares have expired; and

an amendment or modification which changes the sales or purchase prices or price ranges, the amount of Stock to be sold or purchased or the timing of transactions (or a modification or change to a written formula or algorithm, or computer program that affects the amount, price, or timing of the purchase or sale of the Stock) will be deemed a termination of the Sales Plan.

Indemnification; Limitation of Liability

a. Seller agrees to indemnify and hold harmless Stifel and its directors, officers, employees, agents and affiliates from and against all claims, losses, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) arising out of or relating to the Sales Plan. This indemnification shall survive termination of this Sales Plan.

Notwithstanding any other provision of this Sales Plan, Stifel shall not be liable to Seller for:

special, indirect, punitive, exemplary or consequential damages, or incidental losses or damages of any kind, even if advised of the possibility of such losses or damages or if such losses or damages could have been reasonably foreseen, or

The ability of the parties to obtain documents, witness statements, and other discovery is generally more limited in arbitration than in court proceedings.

The arbitrators do not have to explain the reason(s) for their award unless, in an eligible case, a joint request for an explained decision has been submitted by all parties to the panel at least 20 days prior to the first scheduled hearing date.

The panel of arbitrators may include a minority of arbitrators who were or are affiliated with the securities industry.

The rules of some arbitration forums may impose time limits for bringing a claim in arbitration. In some cases, a claim that is ineligible for arbitration may be brought in court.

The rules of the arbitration forum in which the claim is filed, and any amendments thereto, are incorporated into this Agreement.

Any account maintained by you at any time with Stifel, any entity affiliated with Stifel that is a FINRA member firm, or any clearing agent of Stifel, whether maintained by you individually and for your own benefit, jointly with any other person or entity, or in any representative capacity, including, but not limited to, as a trustee or guardian;

Any account in which you claim a beneficial interest maintained by any person other than you with Stifel, any entity affiliated with Stifel that is a FINRA member firm, or any clearing agent of Stifel;

Waiver of Rights to Trial by Jury. In the unlikely event any controversy or dispute between you and Stifel is determined to be ineligible for arbitration or not required to be arbitrated, you agree as follows: THE PARTIES TO THIS AGREEMENT SHALL NOT EXERCISE ANY RIGHTS THEY MAY HAVE TO ELECT OR DEMAND A TRIAL BY JURY. YOU AND STIFEL HEREBY EXPRESSLY WAIVE ANY RIGHT TO A TRIAL BY JURY. You acknowledge and agree that this provision is a specific and material aspect of the agreement between the parties and that Stifel would not enter into this Agreement with you if this provision were not part of the agreement.

Forum Selection Clause. Without limiting in any respect the arbitration agreement above and your agreement and obligation to arbitrate all Disputes, any suit, claim, or action filed against Stifel or its present or past parents, subsidiaries, affiliates, officers, agents, or employees in court shall be brought and heard only in the State of Missouri in St. Louis County Circuit Court. Entering into the Agreement constitutes your consent to submit to the personal jurisdiction of the courts of the State of Missouri.
