Stock Ownership Limitations

As a reminder to investors, Employers Holdings, Inc. (“EIG”) owns several insurance companies, domiciled in several
different states. These wholly-owned insurers are regulated by insurance commissioners and are subject to the statutes and
regulations of the various states where they are domiciled and authorized to transact insurance. As a result, EIG has the
following stock ownership limitations, which must be satisfied prior to certain stock transactions.

●For a period of five years following the effective date of the Plan of Conversion of EIG, which is February 5, 2007, no
person may directly or indirectly acquire or offer to acquire in any manner beneficial ownership of 5% or more of any class of
EIG’s voting securities without the prior approval by the Nevada Commissioner of Insurance of an application for acquisition
under Section 693A.500 of the Nevada Revised Statutes.

●Under Nevada insurance law, the Nevada Commissioner of Insurance may not approve an application for such acquisition
unless the Commissioner finds that (1) the acquisition will not frustrate the plan of conversion as approved by our members
and the Commissioner, (2) the board of directors of Employers Insurance Company of Nevada has approved the acquisition
or extraordinary circumstances not contemplated in the plan of conversion have arisen which would warrant approval of the
acquisition, and (3) the acquisition is consistent with the purpose of relevant Nevada insurance statutes to permit
conversions on terms and conditions that are fair and equitable to the members eligible to receive consideration.

●Furthermore, any person or entity who individually or together with an affiliate (as defined by applicable law) seeks to
directly or indirectly acquire in any manner, at any time, beneficial ownership of 5% or more of any class of EIG’s voting
securities, will be subject to certain requirements, including the prior approval of the proposed acquisition by certain state
insurance regulators, depending upon the circumstances involved. Any such acquisition without prior satisfaction of
applicable regulatory requirements may be deemed void under state law.
