                                  INTRODUCTION

                  This Amendment No. 4 further amends and supplements the Rule
13E-3 Transaction Statement of Orion Capital Corporation, a Delaware corporation
("Orion"), and Guaranty National Corporation, a Colorado corporation, filed by
Orion on November 5, 1997, as previously amended and supplemented by Amendment
No. 1 dated November 25, 1997, and Amendment No. 2 dated December 1, 1997 and
Amendment No. 3 dated December 8, 1997 (together, the "Schedule 13E-3").

                  The Schedule 13E-3 relates to the tender offer by Orion to
purchase all outstanding shares of common stock, par value $1.00 per share
(including any associated stock purchase rights) (the "Shares"), of Guaranty for
$36.00 per Share, net to the seller in cash, upon the terms and subject to the
conditions set forth in Orion's Offer to Purchase dated November 5, 1997 (the
"Original Offer to Purchase") as supplemented by the Supplement to the Offer to
Purchase dated December 1, 1997 (together referred to as the "Offer to
Purchase") and the related Letter of Transmittal, which, together with
amendments and supplements thereto, constitute the "Offer." The Offer terminated
by its terms on the Expiration Date, Friday, December 5, 1997, at 12:00
midnight, New York City time.

                  The Offer was made pursuant to the Agreement and Plan of
Merger dated October 31, 1997 between Orion and Guaranty, which provides for the
merger (the "Merger") of a wholly-owned subsidiary of Orion with and into
Guaranty. If the Merger is consummated, each Share outstanding immediately prior
to the time when the Merger becomes effective, other than Shares as to which
dissenter's rights of appraisal shall have been duly asserted and perfected
under the Colorado Business Corporation Act and Shares held by Orion, its
wholly-owned subsidiaries and Guaranty, will be converted into the right to
receive $36.00 in cash per Share, without interest, all as more fully described
in the Offer to Purchase referred to herein.

                  This Amendment No. 4 to the Transaction Statement is being
filed jointly by Orion and Guaranty. By filing this Schedule 13E-3, neither of
the joint signatories concedes that Rule 13e-3 under the Securities Exchange Act
of 1934, as amended, is applicable to the Offer or the Merger or the other
transactions contemplated by the Agreement and Plan of Merger.
