AND SUMMARY PLAN DESCRIPTION

FOR

CONVERGYS CORPORATION SEVERANCE PAY PLAN

This is a combined Plan and Summary Plan Description of the Convergys Corporation Severance Pay Plan (the “Plan”) as approved by the Convergys Corporation Board of Directors on December 9, 2008. It explains if you are eligible to receive severance benefits, and if so, how benefits will be calculated and paid. The Plan becomes effective on the Effective Date, and replaces, unless specifically exempted as of that date any and all prior policies, plans or arrangements (whether written or unwritten) including, but not limited to any change of control agreements, about payments to be made after termination of employment directly by the Employer other than via an Employer retirement plan or arrangement or any individualized arrangements between the Employer and Employee.

The adoption and continuation of the Plan are voluntary on the part of the Company and the Employer and are not intended to create any contract of employment. This Plan is a welfare plan under the Employee Retirement Income Security Act of 1974 (“ERISA”). This Plan shall continue in effect until changed or terminated.

SECTION 1

PURPOSE OF THE PLAN

The purpose of this Plan is to provide financial assistance to employees whose termination is described within the terms and conditions of the Plan. The benefits of this Plan are designed to help terminated Eligible Employees economically during the period immediately following termination and while they seek alternative employment. It is not intended to imply that severance benefits will be offered to any employee whose employment is terminated by voluntary resignation, for Cause as defined by the Plan, by retirement, or for any other circumstance of termination other than as specifically described herein.

SECTION 2

2.7 “Employee” means any person who works and resides in the United States at the role/level of A or above and is classified by an Employer as an employee for tax reporting of wages (which would not include those who are classified by the Employer as independent contractors or those on the payroll of others who work for the Employer for a time), including officers, but not including (a) directors who are not otherwise employed by an Employer, (b) employees as classified on an Employer’s payroll as temporary, seasonal, student, or part time, or (c) any employee whose employment is, or becomes, the subject matter of a collective bargaining agreement between employee representatives and the Employer unless such collective bargaining agreement expressly provides that such person is eligible for participation in the Plan. Any individual not treated as an employee for tax reporting of wages by an Employer, who subsequently is reclassified as an employee for tax reporting of wages, shall nonetheless be precluded from participating in the Plan for the period in which originally not classified as an employee.

SECTION 3

PARTICIPATION

3.1 Eligibility. All Employees are eligible to participate in this Plan, if their employment is terminated in a circumstance described in Section 3.2 (an “Eligible Employee”). Benefits will be paid hereunder only if the Eligible Employee timely agrees to the waiver and release of claims and non-compete and/or non-disclosure referenced in Section 3.3.

3.2 Covered Events of Termination. An Employee who reaches a Termination Date on account of termination by the Employer (or at Employee’s election via a voluntary program for reduction in force, that specifically provides for benefits under this Plan) shall be an “Eligible Employee” provided that the Employee:

(a) Has not resigned, even if on account of death, disability, or other inability to work,

(b) Has not failed to accept new employment with the Employer which the Plan Administrator finds comparable to the Employee’s job (in pay, position, and within 50 miles of the prior location to be determined as the shortest distance between two points as measured on a map or “as the crow flies”) prior to the Termination Date,

3

Employer and its employees, including any claims arising out of employment and separation from employment. No payment of benefits under this Plan will be made until the Release has been signed, and returned by the deadline stated by the Employer and any period for its revocation has expired.

In addition to signing the Release, all Employer equipment or property in the possession of any employee, including but not limited to Employer credit cards, keys, identification badges, security cards, laptop computers, cellular telephones, parking passes and other electronic equipment, must be returned to the Employer and all personal belongings should be removed from each employee’s office or work space no later than seven days after the Employee’s Termination Date. Employees may arrange with the Human Resources Department a mutually convenient time to return Employer property and pick up personal effects.

3.4 Benefits Not Vested. Under no circumstances is any person automatically entitled to a benefit under this Plan. The Employer shall have the sole discretion to determine whether any one or more of the exclusions listed in Section 3.2 apply to an Employee’s termination of employment, and the Employer is not acting as a fiduciary when determining eligibility under the Plan.

4.2 Limitations of Benefits: This Plan is in lieu of any other plan or program and not in addition to any amounts due under any other plan, program or agreement between the Employer and an Employee providing for continuation of pay or other benefits beyond active employment. The benefits payable hereunder will be reduced dollar for dollar for any amounts payable under any other such arrangement.

Other arrangements may, however, reference this Plan with regard to the time and process for payment of severance benefits.

4.3 Payment of Benefits. Severance Pay will commence at the first regular payroll period at least seven days after the delivery of the executed Release, provided the Release has not been revoked by that date. The benefits under this Plan shall be paid in a lump sum for Eligible Employees at or below level/role D, and for those separating at or above level/role E, one half at least eight days after delivery of the Release and one half six months after the Termination Date. Any payments to an individual who is a “specified employee” (within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (Section 409A)) on his or her Termination Date and to the extent that any amounts payable or other benefits receivable pursuant to this Plan provide for a “deferral of compensation” within the meaning of Section 409A, then, notwithstanding anything to the contrary in this Plan, such payments or benefits will be provided, to the extent necessary to comply with Section 409A, no earlier than the first business day following the six-month anniversary of the Termination Date. Any payment under this Plan shall be net of (i) any outstanding loans, debts, travel advances, or charges for Company property that has not been turned in by the date payment begins (provided that this reimbursement right shall apply only to payments that are exempt or otherwise not deferred compensation subject to 409A), and (ii) by any tax withholding or other payroll deductions authorized by the Employee or required by law. Payment of benefits will continue for the scheduled period beyond death of an Eligible Employee, to the surviving spouse, if any, and if none, to the Eligible Employee’s estate. With respect to benefits that are considered deferred compensation not otherwise exempt from Section 409A, the executed Release must be received and the first benefit payment made no later than 74 days after the Termination Date, subject to the six month delay for specified employees.

If the present value of all payments, benefits, and accelerated vesting of benefits or awards that were received pursuant to this Plan or otherwise from the Company constitutes a “parachute payment” as defined in Section 280G(b)(2) of the Internal Revenue Code, and such parachute payment exceeds the limitation under Section 280G (i.e. three times the base amount, (as defined in Section 280G(b)(3)) by more than 15 percent, the Eligible Employee also will receive an amount equal to the excise tax imposed under Section 4999 of the Code, including any interest or penalties with respect to such excise tax, which amount will be grossed-up to cover the taxes applicable to such payments, excluding any income taxes and penalties imposed pursuant to Section 409A of the Code. Such amount will be paid at the same time the benefits payable in cash under this Plan are paid, but in no event later than the year next following the year in which such excise taxes are remitted to the taxing authority. Notwithstanding the previous sentence, if the present value of all payments, benefits, and accelerated vesting of benefits or awards that are received pursuant to this Plan or otherwise from the Company constitutes a “parachute payment” as defined in Section 280G(b)(2) and such parachute payment does not exceed the limitation under Section 280G by more than 15%, the amount of the cash payment entitled to be received under the terms of this Plan will be reduced to an amount that does not exceed the Section 280G limitation (but not below zero).

9

4.4 Funding. The Employer will pay benefits from its general assets. No specific amount shall be set aside in advance for this purpose. Eligible Employees shall be unsecured general creditors of the Employer for purposes of benefits due hereunder.

4.5 Termination of Benefits. Notwithstanding anything contained herein to the contrary, if an Employee is rehired by Employer in a position commensurate with Employee’s experience and training, such Employee’s benefit shall cease as of his date of rehire and no further benefits shall be owed under the Plan. If the Employer reasonably determines that an Employee is violating the terms of any confidentiality, invention assignment, or noncompete, or other obligation to which the Employee is otherwise subject, the Employer may cease future payments to be made hereunder.

10

6.2 Denial of Claim. If an Employee’s claim for benefits is wholly or partially denied by the Claims Administrator, a written or e-mail notice of such decision shall be furnished by the Claims Administrator to the claimant within 90 days of receipt of the claim unless special circumstances require an extension of time for processing the claim (but the extension may not be for more than an additional 90 days) and shall set forth:

(a) The specific reason or reasons for denial;

(b) A reference to pertinent Plan provisions on which the denial is based;

(c) A description of any additional material or information necessary for the claimant to perfect the claim and an explanation of the claims review procedure set forth in this Section; and

6.3 Claims Review Procedure. If an Employee who has been denied a claim files, within 60 days after its receipt of such denial, a written request for review, setting forth the alleged reasons why his or her claim was improperly denied, the Plan Administrator shall fully and fairly review such decision and advise the claimant in writing of its decision and the reasons therefor within 60 days after the Plan Administrator receives such request for review.

In the event of special circumstances, the time for response may be delayed for an additional period of up to 60 days, but written notice thereof must be given to the claimant within the initial 60 day period of the special circumstances and the date the claimant may expect to receive a decision on appeal. The decision on appeal will contain:

(a) Specific reasons for the denial;

(b) Specific references to the Plan provisions on which the denial is based;

(c) A statement that the claimant will be provided with, upon reasonable request, reasonable access to, and copies of, all documents, records and other information relevant to the claim; and

SECTION 8

ADDITIONAL RIGHTS UNDER THE PLAN

An Eligible Employee in the Plan is entitled to certain rights and protections under the Employee Retirement Income Security Act of 1974 (“ERISA”). ERISA provides that all Plan Eligible Employees shall be entitled to:

12

In addition to creating rights for Plan participants, ERISA imposes duties upon the people who are responsible for the operation of the employee benefit Plan. The people who operate your Plan, called “fiduciaries” of the Plan, have a duty to do so prudently and in the interest of you and other Plan participants and beneficiaries. No one, including your employer or any other person, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a welfare benefit or exercising your rights under ERISA.

If your claim for a welfare benefit is denied or ignored, in whole or in part, you have a right to know why this was done, to obtain copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules.

Under ERISA, there are steps you can take to enforce the above rights. For instance, if you request a copy of Plan documents or the latest annual report from the Plan and do not receive them within 30 days, you may file suit in a Federal court. In such a case, the court may require the Plan administrator to provide the materials and pay you up to $110 a day until you receive the materials, unless the materials were not sent because of reasons beyond the control of the administrator. If you have a claim for benefits which is denied or ignored, in whole or in part, you may file suit in a state or Federal court. If it should happen that plan fiduciaries misuse the Plan’s money or you are discriminated against for asserting your rights, you may seek assistance from the U.S. Department of Labor, or you may file suit in a Federal court. The court will decide who should pay court costs and legal fees. If you are successful the court may order the person you have sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees, for example, if it finds your claim is frivolous.

If you have any questions about your Plan, you should contact the Plan Administrator. If you have any questions about this statement or about your rights under ERISA, or if you need assistance in obtaining documents from the Plan administrator, you should contact the nearest office of the Pension and Welfare Benefits Administration, U.S. Department of Labor, listed in your telephone directory or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue N.W., Washington, D.C. 20210. You may also obtain certain publications about your rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

SECTION 9

GENERAL PROVISIONS

9.1 Not an Employment Contract. Neither this Plan nor any action taken with respect to it shall confer upon any person the right to continued employment with the Employer.

It is intended that the payments and benefits provided under the Plan will be exempt from the applications of, or comply with, the requirements of 409A.
