ITEMS 1 THROUGH 9, AND ITEM 11.

      This Amendment No. 17 ("Amendment No. 17") to Tender Offer Statement on
Schedule TO (this "Schedule TO") amends and supplements the statement originally
filed on June 22, 2006, as amended, by Steel Partners II, L.P., a Delaware
limited partnership ("Steel Partners II"), and BZ Acquisition Corp. (the
"Purchaser"), a Delaware corporation and a wholly owned subsidiary of Steel
Partners II. This Schedule TO relates to the offer by the Purchaser to purchase
all outstanding shares of common stock, par value $0.01 per share (the "Common
Stock"), and the associated preferred stock purchase rights (the "Rights" and,
together with the Common Stock, the "Shares"), of Bairnco Corporation, a
Delaware corporation (the "Company"), at $13.50 per Share, net to the seller in
cash, without interest, upon the terms and subject to the conditions set forth
in the Amended and Restated Offer to Purchase, dated March 2, 2007 (as amended
or supplemented, the "Offer to Purchase"), and in the related Amended and
Restated Letter of Transmittal (the "Letter of Transmittal"), copies of which
are attached hereto as Exhibits (a)(1)(viii) and (a)(1)(ix), respectively
(which, together with any amendments or supplements thereto, collectively
constitute the "Offer"). The information set forth in the Offer to Purchase,
including the Supplement thereto dated March 30, 2007, a copy of which is
attached hereto as Exhibit (a)(1)(xiii), and the related Letter of Transmittal
is incorporated herein by reference with respect to Items 1 through 9 and 11 of
this Schedule TO. Capitalized terms used but not defined herein shall have the
meaning assigned to such terms in the Offer to Purchase.

ITEM 10.    FINANCIAL STATEMENTS.

      Not applicable.

ITEM 11.    ADDITIONAL INFORMATION.

      On March 30, 2007, Steel Partners II issued a press release announcing
that, as permitted by the Merger Agreement with the Company, it may transfer its
entire interest in the Purchaser to WHX Corporation, a Delaware corporation and
an affiliate of Steel Partners II (the "BZA Transfer"). As a result, WHX
Corporation has been included as an offeror in this Schedule TO. The BZA
Transfer will not result in the amendment or addition of any conditions to the
consummation of the Offer. If the BZA Transfer is consummated, Steel Partners II
intends to tender all Shares owned by it into the Offer, and the transaction
valuation set forth in the fee table on the cover page of this Schedule TO has
been increased accordingly. The press release issued by Steel Partners II is
attached hereto as Exhibit (a)(5)(xx).
