News Regarding Your Long-Term Incentives

You are receiving this message because you are a current participant in the Gerdau Long-Term Incentive Program.

As part of the continuous review and improvement process, Gerdau is modifying the Long-Term Incentive (LTI) program to better align with the program objectives which are attraction, retention, motivation, and alignment with shareholders and market trends.

In 2014, LTI awards will be granted as Restricted Stock Units (RSUs) and Performance Share Units (PSUs).  Over the next few months, in preparation for this transition, you will be given an opportunity to make a one-time election to convert your outstanding Stock Appreciation Rights (SARs) or stock options to an equivalently-valued number of RSUs.

During the next week you will receive information about the new 2014 program and the exchange offer.  Please be on the lookout for an invite to webinars or local onsite meetings.

In addition, next week you will receive an email with links to the exchange offer, your personalized exchange statement, as well as links to other documents that will be provided to help you make an informed decision about your awards.

These materials will be sent to you in an email from Gerdau with links to the appropriate documents.  Following the presentations, please direct your questions to aneta.booth@gerdau.com.
