YOUR VOTE IS IMPORTANT

TWO-THIRDS VOTE REQUIRED

PLEASE VOTE YOUR PROXY TODAY!

September 9, 2004

Dear Stockholder:

The Special Meeting of Stockholders of The First Years Inc. to be held on September 14, 2004, is only a few days away.

Time is short and your vote is important. The proposed merger agreement of RC2 Corporation and The First Years requires the approval of two-thirds of the outstanding shares of The First Years common stock. By not voting, it has the same affect as voting “Against” the merger agreement.

Please submit your vote in this important matter regarding the future of your investment – by voting by telephone, via the Internet, or by marking, signing, dating and returning the enclosed proxy in the postage-paid return envelope provided. Telephone and Internet voting may be used until 11:59 p.m., Eastern Daylight Time, on Monday, September 13, 2004.

If you hold your shares in street name at a custodian bank or broker, please call the person responsible for your account and instruct him or her to vote your shares in support of the merger agreement.

The Board of Directors and the Special Committee of The First Years recommend that stockholders vote “FOR” the adoption and approval of the merger agreement.

For more information or for assistance voting your shares, please call D. F. King & Co., Inc., who is assisting us, toll-free at 1-800-859-8508.

Thank you for your continued support.

Sincerely,

/s/ Ronald J. Sidman
