                                  INTRODUCTION


      This Statement is filed by Orion Capital Corporation ("Orion") This
Statement relates to the tender offer of 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 National Corporation, a
Colorado corporation ("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
which is attached hereto as Exhibit (a)(10) (together referred to as the "Offer
to Purchase") and the related Letter of Transmittal which together with
amendments or supplements thereto constitute the Offer (the "Offer"). The Offer
is being made pursuant to the Agreement and Plan of Merger dated October 31,
1997 between Orion and Guaranty, which also 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 dissenters' rights
of appraisal have been duly and timely asserted and perfected under the Colorado
Business Corporation Act, and Shares held by Orion, its wholly-owned
subsidiaries or 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.




                                       2

      This Statement amends the Schedule 14D-1 of Orion dated November 5, 1997
(as hereby amended, the "Schedule 14D-1") by incorporating by reference herein
the information set forth in the press release, dated December 1, 1997 of Orion
attached hereto as Exhibit (a)(11). This Statement also amends Items 10 and 11
by adding the information set forth below. Except as otherwise indicated herein,
the Schedule 14D-1 remains unchanged in all respects. Capitalized terms not
defined herein are deemed defined as set forth in the Offer to Purchase and
Orion's Tender Offer Statement on Schedule 14D-1.
    

Item 10. Additional Information.

      The following information is hereby added to Item 10 of the Schedule
14D-1:

       (a). All conditions to the Offer, other than receipt of necessary
governmental approvals, must be satisfied or waived prior to the acceptance of
Shares for payment pursuant to the terms of the Offer. When a condition has not
been satisfied the existence of which is to be determined in the sole discretion
of Orion, Orion will exercise its reasonable good-faith judgment in determining
whether the occurrence or non-occurrence of the event giving rise to such
condition makes it inadvisable to proceed with the Offer or with acceptance for
payment for the Shares.

References in "THE OFFER -- Section 10. Certain Conditions of the Offer" of the
Original Offer to Purchase to Orion's right to terminate, amend or extend the
Offer or to delay acceptance for payment or payment if all conditions are not
satisfied or waived should not be interpreted as reserving to Orion the right to
accept Shares and subsequently to invoke the existence of a condition as a basis
on which to withhold payment for and return of the Shares tendered and accepted.
The reservation by Orion of the right to delay payment for Shares is subject to
the provisions of applicable law under Rule 14e-1 promulgated under the Exchange
Act, which require that Orion pay the consideration offered or return the Shares
deposited by or on behalf of shareholders promptly after termination or
withdrawal of the Offer.



       (f) The information set forth in the Supplement to the Offer to Purchase
dated December 1, 1997, a copy of which is attached as Exhibit (a)(10) hereto is
incorporated herein by reference.
