Subject:  Hertz/Dollar Thrifty Acquisition Update

Sent on behalf of Scott Thompson…

Since our last communication, we want you to know that Dollar Thrifty and Hertz are still actively engaged in seeking the Federal Trade Commission’s approval for the merger.  I understand that during this period you may be feeling anxiety. Hertz and Dollar Thrifty hope you will recognize that until the next step of government approval is reached, neither company is able to provide specific answers to many of your questions.  If antitrust clearance is obtained and the other conditions to closing are satisfied, the parties will complete the merger, and once that is finalized, a transition period will take place to integrate the companies.

Lynne Pritchard, our Senior VP of Human Resources has been collecting your questions.  Many of these relate to paid time off, Group RSP, severance, company stock, health and wellness benefits, seniority, and processes related to the integration. Please continue to submit your questions through employee.questions@dtag.com.

Frequently Asked Questions

Will I be able to roll my current DTAG Group RSP account into the Hertz Group RSP Plan?

Yes, it is expected that current DTAG Group RSP Plan account balances will be transferred into the Hertz Group RSP Plan after the transaction closes. Specifics on this process will be provided once a transition plan is finalized. 

What is DTAG’s severance policy? 

Severance calculations are based upon various factors including length of service and grade level. Severance is comprised of continuation of base salary and health benefits at current employee pricing for the length of the severance period. Severance is provided to both full time and part time employees. More specific information will be shared with you individually as we move further into the transition.

Will I be required to join a union?

The vast majority of Hertz employees choose to be union free.  DTAG employees have the legal right to remain union free.  Hertz does not force, or encourage employees to be members of unions and there is absolutely no requirement or law mandating that any DTAG employee join a pre-existing union at Hertz. In fact, Hertz has told us that Hertz prefers to deal directly with its employees.

Will our existing seniority with DTAG align with Hertz seniority?

Yes, your DTAG date of hire will generally be honored by Hertz in determining service credits under Hertz benefit plans to the extent such service was recognized under a comparable DTAG plan.

Will our health and welfare benefits continue under Hertz?

Hertz agrees with Dollar Thrifty that nothing will change abruptly related to your benefits, and you will be provided adequate time and information to fully understand any new benefit offerings, options or changes.  Hertz has committed in the merger agreement to providing DTAG employees (excluding any employee covered by a collective bargaining agreement) substantially similar compensation and benefits overall to those provided under current DTAG plans through December 2013. Specific details and administration of benefit programs such as healthcare, Paid Time Off, tuition reimbursement, etc. will be shared by Hertz as the transition progresses. Hertz will also conduct informational meetings and in some cases on-site visits to ensure you have a full understanding of any benefit changes and the timelines.

We will continue to provide communications as we are able to deliver more details.

These statements are based on certain assumptions that each of Hertz and Dollar Thrifty have made in light of their experience in the industry as well as their perceptions of historical trends, current conditions, expected future developments and other factors that Hertz and Dollar Thrifty believe are appropriate in these circumstances. We believe these judgments are reasonable, but you should understand that these statements are not guarantees of performance or results, and our actual results could differ materially from those expressed in the forward-looking statements due to a variety of important factors, both positive and negative.
