June 16, 1998 AN IMPORTANT REMINDER --------------------- Dear Unitholders: Consent Solicitation materials were sent to you recently. The consent relates to several amendments to the Buckeye Partnership Agreement that will eliminate restrictions on management's ability to issue additional LP Units, incur debt and spend capital. These amendments will provide the Partnership with the financial flexibility to pursue growth and expansion opportunities in a timely and cost-effective manner. According to our records, your consent, which will expire on July 17, 1998 has not yet been received. Regardless of the number of units you own, it is important that they be represented. YOUR VOTE IS EXTREMELY IMPORTANT Since the time remaining is short, we urge you to sign, date and mail the enclosed consent promptly. We must receive the affirmative consent of at least two-thirds of the unitholders for the amendments to be approved. Failure to consent will have the same effect as a vote against the amendments. Your interest and participation in the affairs of your company are sincerely appreciated. If you have questions or need additional consent materials, please call D. F. King & Co., Inc. at (800) 628-8509. Sincerely, /s/ A. W. Martinelli ------------------------------------ A. W.
