The Shareholder Option Agreement is described in Section 11 of the Offer to Purchase dated as of October 21, 1999 filed as Exhibit (a)(1) to this Schedule 14D-1. Because Parent owns all of the capital stock of Purchaser, Parent may be deemed to beneficially own the Shares subject to the Shareholder Option Agreement.

This Amendment No. 2 amends and supplements the joint Tender Offer Statement on Schedule 14D-1 (as amended and supplemented, the "Schedule 14D-1") filed with the Securities and Exchange Commission on October 21, 1999 as previously amended by Amendment No. 1 on November 4, 1999 by United Technologies Corporation, a Delaware corporation ("Parent") and by Sphere Corporation, a Wisconsin corporation ("Purchaser") and a wholly owned subsidiary of Parent, to purchase all of the outstanding shares of common stock, par value $.001 per share (the "Common Stock"), of Cade Industries, Inc., a Wisconsin corporation (the "Company"), including the associated common stock purchase rights (the "Rights") issued pursuant to the Rights Agreement (the "Rights Agreement") dated as of August 4, 1998, as amended as of October 21, 1999, between the Company and Firstar Bank Milwaukee, N.A. (formerly named Firstar Trust Company), as Rights Agent (the Common Stock and the Rights together, the "Shares") at $5.05 per Share, net to the seller in cash, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated as of October 21, 1999, and the related Letter of Transmittal (which together constitute the "Offer"). Capitalized terms used and not defined herein shall have the meanings assigned to such terms in the Offer to Purchase and the Schedule 14D-1. This Amendment also constitutes an amendment to the Statement on Schedule 13D with respect to the beneficial ownership of Shares which has previously been filed by Parent and Purchaser. Item 10.
