HQ Relocation - Employee Questions Master List

Decision Process

1. What criteria were used when choosing the location for the new HQ?

Both companies worked together to conduct a detailed analysis. We wanted to make sure we explored all avenues in order to come up with the best decision. We investigated such areas as:

• Space and flexibility for expansion of existing facilities

• Terms of leases

^¡   Rent and operating costs

• Airport access, number of available flights, flight costs

• Central geographic location for a national company

• Food service, hotel and conference facilities

• Parking

2. Is the choice of headquarters based on who was appointed CEO and CFO of the new company?

Not at all. The headquarters decision was made jointly by Dex One and SuperMedia leadership after a thorough evaluation of all options based on specific business criteria.

General

1. How many Cary/Morrisville employees will be laid off as a result of the new headquarters location?

No decisions about job eliminations have been made at this time. Those decisions will be made during the integration planning process over the next few months.

2. Will the new company keep a presence in Cary/Morrisville or other major locations?

We expect to maintain a presence in the area. Exact plans for Cary/Morrisville and other Dex One and SuperMedia locations will become clearer as we work through the integration planning process and evaluate the best use of all existing facilities for the combined company. Sales offices should not be affected except for the few cities where we have overlapping territories.

3. If the company is keeping a presence in Cary/Morrisville, how many employees and what job functions will remain in the area?

No decisions about specific job functions to remain in Cary/Morrisville have been made. Those decisions will be made during the integration planning process.

Relocation

1. Which employees will be asked to relocate?

There will be opportunities for some employees to relocate. However, no decisions about specific job functions or personnel to relocate have been made. Those decisions will be made during the integration planning process.

2. What are the criteria for selecting which employees will be asked to relocate?

Decisions about specific positions and relocation opportunities will be made as part of the integration planning process.

3. If we are asked to relocate what relocation services/packages will be offered?

Relocation program details will be shared with eligible employees once these decisions are made as part of the integration planning process.

4. How long will we be given to decide if we want to take the position in another office?

Our intention is to provide a reasonable amount of time for employees to decide if they wish to accept a relocation opportunity, while minimizing any potential disruption to the business.

5. If I decline a relocation opportunity, am I still eligible for severance benefits?

Generally, yes, subject to meeting certain conditions of the plan. For example, employees must remain employed by the company through the date their position is eliminated to be eligible for severance benefits.

2

6. Will Cary/Morrisville employees be allowed to apply for available positions at other Dex Media locations including the new headquarters?

Yes.

7. If I apply for a position in another location, will relocation assistance be provided?

Relocation assistance eligibility will depend upon a variety of factors, including the particular position, work location, budget, etc.

Timing

1. When will we know our individual employment status?

No decisions about job eliminations have been made. Those decisions will be made during the integration planning process, but we do not anticipate such decisions will be finalized or communicated to employees until after the transaction closes.

2. How much notice will we be given if our position is eliminated?

The company will provide as much notice as possible to employees whose positions will be impacted.

3. When will the process of transferring responsibilities begin?

We expect decisions regarding the transfer of job responsibilities will be made during the integration planning process; however, none of the actual transition work will begin until after the transaction closes.

4. By when should we expect the process to be completed?

We anticipate that through the integration planning process, various functions will adopt different transition timelines based upon the needs of their clients and function.

Human Resources

1. What kind of severance packages will be offered?

Generally, if an employee’s position is eliminated as a result of the merger, the employee will be eligible for severance benefits if he/she meets certain requirements under the severance plan, such as remaining employed through the scheduled separation date. Severance benefits vary based on job level and length of service with the company.

3

2. If I find another job and leave before the date my position is eliminated, am I still eligible to receive a severance package?

No.

3. Will Dex be offering employment transition services?

Yes. Specific services will be communicated to eligible employees in conjunction with a notification of eligibility for severance benefits.

4. For how long after I am terminated will I be able to keep my health insurance?

Under the current group benefits plan, an eligible employee’s coverage ends at the conclusion of the month in which his/her employment ends. After this point, an enrolled employee is eligible to continue coverage through COBRA.

5. How will this affect my 401(k) or pension benefits?

There is no impact on your 401(k) or pension benefits at this time. If your employment ends, you will be eligible for the various distribution options available under the applicable plan(s).

6. If I have specific questions, who should I call?

Please reach out to your HR Generalist for assistance.

1. When will the deal close?

We expect the transaction to close in the fourth quarter of 2012.
