provisions of this Section 4 will be enforceable as so modified. You further agree that if any part of this Section 4 is held by a court or arbitrator with competent jurisdiction to be invalid, illegal or incapable of being enforced in whole or in part by reason of any rule of law or public policy, and cannot be modified in accordance with this Section, such part shall be deemed to be severed from the remainder of this Section 4 for the purpose only of the particular legal proceedings in question, and all other covenants and provisions of this Retirement Agreement shall in every other respect continue in full force and effect, and no covenant or provision shall be deemed dependent upon any other covenant or provision.

6. Injunctive Relief; Clawback. You and the Company agree that upon a final determination by a court of competent jurisdiction of a material violation of your obligations in Sections 4 and 5 of this Retirement Agreement, such violation may cause irreparable injury to the relevant DST Entity or DST Plan that is not adequately remediable in damages and may entitle the DST Entity or DST Plan to temporary, preliminary and final injunctive relief against further breach of such obligations.

Each amount to be paid or benefit to be provided under this Retirement Agreement shall be construed as a separate identified payment for purposes of Code Section 409A. Without limiting the foregoing and notwithstanding anything contained herein to the contrary, to the extent required in order to avoid an accelerated or additional tax under Code Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to this Retirement Agreement (or any plans or agreements referenced herein) during the six-month period immediately following your separation from service shall instead be paid as soon as administratively practical after the date that is six months following your separation from service (or, if earlier, your date of death). To the extent required to avoid an accelerated or additional tax under Code Section 409A, amounts reimbursable to you shall be paid to you on or before the last day of the year following the year in which the expense was incurred and the amount of expenses eligible for reimbursement (and in kind benefits provided to you) during one year may not affect amounts reimbursable or provided in any subsequent year. In no event whatsoever shall the Company be liable for any additional tax, interest or penalty that may be imposed on you by Code Section 409A or damages for failing to comply with Code Section 409A.

8. Press Release. Within four (4) business days following the date that you execute this Retirement Agreement, the Company will issue a press release substantially in the form attached hereto as Addendum A.

9. Captions and Section Headings. Captions and section headings used here are for convenience and are not a part of this Agreement and will not be used in its interpretation.

10. Response to Subpoena, Court Order or Similar Legal Process. Nothing in this Retirement Agreement shall prohibit any DST Entity, DST Plan, or any of the DST Entities’ or DST Plans’ shareholders, directors, officers, managers,

partners, employees, attorneys, advisors and agents (each, a “DST Person”) or you from responding to a subpoena, court order or similar legal process or from cooperating, as required by law, with any governmental investigation; provided, however, that prior to making any disclosures required by a subpoena or other court order, the Company or you shall provide the other party with written notice of the subpoena, court order or similar legal process sufficiently in advance of such disclosure to afford the other party a reasonable opportunity to challenge the subpoena, court order or similar legal process.

11. Successors and Assigns. This Retirement Agreement shall inure to the benefit of and be binding upon each of the DST Entities and DST Plans and any successor organization which shall succeed to any of the DST Entities or DST Plans by acquisition, merger, consolidation or operation of law, or by acquisition of assets of any of the DST Entities or DST Plans and any assigns. You may not assign any of your obligations under this Retirement Agreement.

12. Waiver. The failure of the Company or you to enforce any provision of this Retirement Agreement will not waive, in any way, that or any other provision of this Retirement Agreement in connection with any future violation, or prevent that party or any other party from thereafter enforcing every term of this Retirement Agreement.

13. Withholding; Authorized Deductions. The Company shall be entitled to withhold from amounts to be paid to you hereunder any federal, state or local withholding or other taxes which it is from time to time required by law to withhold and any deductions authorized by you.

14. Each Party the Drafter. This Retirement Agreement, and the provisions contained in it, shall not be construed or interpreted for, or against, any party to this Retirement Agreement because that party drafted or caused that party’s legal representatives to draft any of its provisions.

15. Counterparts. This Retirement Agreement may be executed simultaneously in counterparts, each of which shall be an original, but all of which shall constitute but one and the same agreement. A faxed or PDF signature shall operate the same as an original signature.

16. Governing Law. This Retirement Agreement will be governed by and construed according to the laws of the State of Missouri without regard to the application of any choice-of-law rules that would result in the application of another state’s laws.

17. Entire Agreement; No Admission of Wrongdoing. This Retirement Agreement sets forth the entire agreement between you and the Company and any DST Entity or DST Plan and replaces or supersedes any other oral or written agreement, proposals, negotiations or understandings between you and the Company and any DST Entity or DST Plan, except as otherwise provided in the Retirement Agreement with respect to continuing obligations under any existing noncompete, nonsolicitation, nondisclosure and intellectual property protection obligations under the Employment Agreement and the Award Agreements, the Recoupment Policy, obligations under the Ethics and HR Policies, and obligations under the Arbitration Policy set forth on Addendum B hereto. The Company has made no representations, agreements or promises other than the representations, agreements and promises specifically stated in this Retirement Agreement. Any disputes between you and any DST Entity or DST Plan shall be resolved in accordance with the Arbitration policy set forth on Addendum B thereto, subject to the right of either party to seek injunctions in aid of arbitration.

Arbitration Policy

For employment-related legal disputes not resolved through our Open Door Policy or Equal Employment Opportunity (EEO) Policy, the Company has implemented the following Arbitration Policy. We believe the Arbitration Policy provides a fair, efficient, private, and accessible process to resolve employment disputes relating to legal rights. If any employee, former employee, or applicant (all referred to herein as “Associate”) is not satisfied with the result of a complaint under the Open Door Policy and/or the Equal Employment Opportunity Policy, or if an Associate for any reason fails to pursue a complaint under those policies, any claim by the Associate related to legally-protected rights shall be subject to independent and neutral arbitration under the terms of this Arbitration Policy, unless the Associate has properly opted out of the policy by the deadline explained on page 5. This Policy also applies to claims by the Company against an Associate.

How Does the Arbitration Process Work?

The process will be administered by the American Arbitration Association (AAA) and conducted under AAA’s National Rules for the Resolution of Employment Related Legal Claims existing at the time proceedings are initiated, except as modified by this policy. The rules and information about AAA may be found at xxx.xxx.xxx. AAA is a not-for-profit public service organization. Over 4,000,000 workers are covered by various types of plans administered by the AAA.

The Company will pay the Arbitrator fees and the costs charged by AAA, except that the Associate must pay an initial $125.00 fee to AAA if the Associate initiates a claim. (If an Associate is indigent, he/she may file the claim without a fee, pending a decision by the Arbitrator on a request for fee waiver based on the law and applicable AAA Rules.)

The Arbitrator shall be an independent, neutral, and licensed attorney selected from a list of all attorney members of the AAA Regional Employment Dispute Resolution Roster or any successor comparable AAA Roster who are: (1) former federal court judges and magistrates or former state court judges in appellate courts or trial courts of general jurisdiction; or (2) lawyers who have practiced law and/or served as Arbitrators in the field of employment law for at least 15 years and are rated “AV” by Xxxxxxxxxx-Xxxxxxx. The AV rating is for lawyers considered to have reached the height of professional excellence and recognized for the highest levels of skill and integrity. If the AAA Regional Roster for any reason does not provide the names of at least three Arbitrators who meet the qualifications of this policy, then additional qualified Arbitrators shall be added to the list from the AAA Regional Roster for the region that is closest geographically to the Associate’s place of employment or prospective employment.

The Company first and then the Associate shall in turn alternately strike one name from the list until there is only one name remaining, who shall be the Arbitrator. On the fourth business day after the day on which the striking is completed, the Company and the Associate shall jointly inform AAA of the Arbitrator selection; however, prior to the fourth

B-1

day and based on review of the importance and complexity of the case and/or the experience of the Arbitrator, either the Company or the Associate unilaterally may expand the number of Arbitrators from one to three by sending written notice to the other party. If either party elects to expand to three the number of Arbitrators, the additional two Arbitrators shall be the last two Arbitrators who were previously struck by the parties from the list of Arbitrators. The party electing to add two Arbitrators to the case shall be solely responsible for all fees and expenses of the two additional Arbitrators. In a case with three Arbitrators, the decision of the three Arbitrators must be unanimous. If only two of the three Arbitrators agree on a decision, they shall issue a written advisory decision which, if accepted in writing by both parties within ten calendar days, shall become a final and binding decision. If there is no unanimous decision or an advisory decision accepted in writing by both the Company and the Associate, the case shall be heard again before a new Arbitrator or Arbitrators under the terms of this policy except that if either the Associate or the Company elects to use three Arbitrators at the second hearing, two Arbitrators shall have the authority to issue a decision. In any case, the Associate and the Company also may agree on a mutually acceptable Arbitrator, and bypass the AAA arbitration selection and administration process.

The Arbitrator shall have the exclusive authority to resolve all disputes relating to the facts or the law, including the authority to grant summary disposition of claims and the authority to grant all relief that a court of competent jurisdiction could grant based on the claims asserted. The Arbitrator shall decide the case in the same manner as a federal district court judge hearing the case without a jury and shall apply the federal rules of evidence. The Arbitrator shall issue a signed written decision stating the findings of all material facts and conclusions of law that provide the basis for the decision. The Federal Arbitration Act governs the enforcement of this Arbitration Policy and proceedings under the policy, other than as modified by this policy. If the Arbitration Policy is found not enforceable under the Federal Arbitration Act, applicable state law shall apply. Other than as provided in this policy, the substantive law applied to claims shall be the state or federal substantive law that would be applied by a federal district court judge sitting at the place of the Associate’s employment or prospective employment.

The arbitration hearing shall be held in the community of the Associate’s principal place of employment or prospective employment, unless another location is agreed to by the parties. Prior to the hearing, the parties shall be entitled to reasonable discovery as determined by the Arbitrator consistent with the objective of fairness, speed and economy, including at a minimum two depositions, ten interrogatories and ten document requests by each party. Associates at their expense may be represented by an attorney. The following persons may be present at the hearing: the Arbitrator and any recorder of the hearing; the Associate and his/her spouse, attorneys, experts, and witnesses; and the Company’s attorneys, management, human resource personnel, experts, and witnesses. No one else may be present without good cause determined by the Arbitrator. The parties shall provide lists of the names and addresses of witnesses and copies of exhibits to each other at least 30 days prior to the hearing and may supplement this information up to 20 days prior to the hearing. The Arbitrator may resolve all discovery disputes, issue protective orders, and issue subpoenas pursuant to the law. Any party may arrange for a qualified court reporter to make a stenographic record of the hearing. The parties shall be entitled to file post-hearing briefs

B-2

and proposed findings of fact and conclusions of law. The Arbitrator shall set a briefing schedule under which the party with the burden of proof files first, the opposing party files next, and the burden of proof party may file a reply.

The Arbitration decision shall be binding on the Company and the Associate, and it may be enforced by a court of competent jurisdiction, subject to available legal grounds for vacating an arbitration award. However, any party also may: (1) within 30 days after the decision file a reconsideration motion or other motion with the Arbitrator or Arbitrators; or (2) within 60 days after the decision or 30 days after a decision on a reconsideration motion or other post-decision motion, serve written notice of an Arbitration Appeal. If a party serves notice of an Arbitration Appeal, the selection of an Arbitrator or Arbitrators to decide the appeal shall be under the procedure of this Arbitration Policy. In an Arbitration Appeal, the Arbitrator or Arbitrators shall apply the standard of review that a court of appeals would apply to the decision of a trial judge sitting without a jury. The Arbitrator or Arbitrators in an Arbitration Appeal shall issue a written decision after considering written briefs and oral argument. If three Arbitrators are selected for an Arbitration Appeal, two Arbitrators shall have the authority to issue a decision. The Arbitration Appeal decision shall be subject to review by a court of competent jurisdiction for error of law or any other available legal grounds for vacating an arbitration award. If the Arbitration Appeal or court review results in the direction of a new hearing or other further proceedings, any party shall have the right to require that a new Arbitrator or Arbitrators be selected under this Arbitration Policy to handle such new hearing or other further proceedings.

How to Assert a Claim

An Associate who wishes to assert a claim must submit a written request for arbitration by Certified Mail/Return Receipt Requested to the Vice President of Human Resources, 000 X. 00xx Xxxxxx, Xxxxxx Xxxx, Xxxxxxxx 00000, within 300 days, or within any longer time period established by the applicable statute of limitations under the law, from the date of the alleged act giving rise to the claim. The written request should include supporting documentation and a thorough description of the facts, the nature of the claim, and the damages and/or other remedies sought. If the Company wishes to assert a claim against an Associate, it also must submit such a written request for arbitration with supporting documentation to the Associate by Certified Mail/Return Receipt requested within 300 days, or within any longer time period established by the applicable statute of limitations under the law, from the date of the alleged act giving rise to the claim. The claim is waived if the Associate or the Company fails to submit a timely and proper written request for arbitration. After a request for arbitration, the parties shall cooperate on a joint submission of the claim to AAA, with the Company paying all fees above $125.00 and, if the Associate asserts indigent status, the Company advancing the initial $125.00 fee on behalf of the Associate. The Associate does not need to pay the $125.00 fee if only the Company asserts a claim.

All claims must be asserted, heard, and resolved on a single Associate basis, unless otherwise agreed to by all parties. All related claims by a party must be asserted in the same arbitration or the unasserted claims are waived. The Company may not assert claims against multiple Associates in the same arbitration. Claims by multiple Associates may not be joined together in the same arbitration. An Associate may not assert claims on behalf of

B-3

multiple Associates or as a class action or collective action either in court or under this Arbitration Policy, and an Associate may not have a claim asserted on his or her behalf by another person as a class representative or otherwise. However, if a final court decision holds this prohibition on class action, collective action, and multiple Associate claims is invalid, the Arbitration Policy is modified as follows for the subsequent resolution of a class or collective action claim or a multiple Associate claim. If any Associate wishes to attempt to assert such a claim after a final court decision holding the prohibition invalid, the claim must first be filed in a court of competent jurisdiction. Under all applicable laws, rules, and procedures, the court shall determine the question of whether the claim should be certified to proceed as a class or collective action or otherwise proceed on behalf of multiple Associates. After a final judicial decision on certification or on multiple Associate status, including all appeals of a trial court ruling, the court then shall refer the claim to arbitration under this policy for a decision on the merits of the claim.

Coverage of Arbitration Policy

This Arbitration Policy covers all legal claims arising out of or relating to employment, application for employment, or termination of employment, except for claims specifically excluded under the terms of the policy. The claims covered by the policy include, but are not limited to, the following types of claims: wrongful discharge under statutory law or common law; employment discrimination, retaliation and sexual or other harassment based on federal, state or local statute, ordinance or governmental regulations; retaliatory discharge or other unlawful retaliatory action; overtime or other compensation disputes; leave of absence disputes; tortuous conduct; defamation; violation of public policy; breach of contract; and other statutory or common law claims. It includes claims by an Associate against the Company and claims by an Associate against any fellow employee, supervisor, or manager based on alleged conduct within the scope of employment by the fellow employee, supervisor, or manager. It also includes claims based on events that occurred prior to the effective date of this policy or based on events that occur following the termination of employment. This Arbitration Policy also applies to any claims by the Company against an Associate.

The only claims excluded from this Arbitration Policy are claims by an Associate for workers’ compensation benefits, unemployment compensation benefits, Employee Retirement Income Security Act (ERISA) -related benefits provided under a Company sponsored benefit plan, or claims filed with the National Labor Relations Board. Additionally, either the Associate or the Company may file a court action seeking provisional equitable remedies available under the law, including but not limited to temporary or preliminary injunctive relief, either before the commencement of or during the arbitration process, to preserve the status quo or otherwise prevent damage or loss pending final resolution of the dispute pursuant to the terms of this Arbitration Policy. Also, this Arbitration Policy does not prevent or discourage an Associate from filing and pursuing an administrative proceeding before the Equal Employment Opportunity Commission or a state or local administrative agency; however, if an Associate chooses to pursue a legal claim in addition to and/or following completion of such administrative proceedings, or if there is some other legal proceeding related to the claim following completion of the administrative proceedings, the claim then shall be subject to the terms of this Arbitration Policy.

Agreeing to the Arbitration Policy

Effective March 12, 2007, the Company and each Associate who continues or starts employment after March 12, 2007 agree as a term and condition of employment, and as a binding contract, to resolve employment-related legal claims through this Arbitration Policy and not through a lawsuit with a judge or jury trial, unless the Associate timely exercises his or her right to voluntarily opt out of this Arbitration Policy by sending a letter by Certified Mail/Return Receipt Requested to the Vice President of Human Resources, DST Systems, Inc., 000 X. 00xx Xxxxxx, Xxxxxx Xxxx, Xxxxxxxx 00000, stating the desire to opt out of the policy. The letter may simply state the following: “I wish to opt out of the Company Arbitration Policy.” For any Associate employed as of March 12, 2007, the opt out letter must be received by the Vice President of Human Resources on or before April 11, 2007. For any Associate who starts employment after March 12, 2007 or who is on leave of absence on March 12, 2007, the opt out letter must be received by the Vice President of Human Resources on or before the date 30 days after the Associate’s first day of employment or 30 days after the Associate’s first day back to work following the leave of absence. There will be no retaliation against any Associate for opting out of the Policy. Associates may contact the Director of Employee Relations or the Vice President of Human Resources at (000) 000-0000 to ask any questions or seek further information regarding this Arbitration Policy. We also encourage Associates, if they desire, to secure advice from an attorney regarding the voluntary opt out option and the Arbitration Policy. Any Associate who does not provide a timely opt out letter by Certified Mail/Return Receipt Requested by the deadline established under this policy is automatically covered by this Arbitration Policy and is required to arbitrate employment-related legal claims under the terms of the Policy.

This Arbitration Policy creates a contract that binds the Company and each Associate to arbitrate employment-related legal claims, unless an Associate properly and timely opts out of the Policy . The Arbitration Policy does not in any way modify the employment-at-will status of any.

The provisions of this Arbitration Policy are severable. That means that if any provision is found invalid or unenforceable by a court, it shall not affect the application and enforcement of the rest of this Arbitration Policy. Also, whenever possible and consistent with the objective of this Arbitration Policy to arbitrate all covered claims, any otherwise invalid term should be reformed and enforced by a court.
